    Attityder, beteenden och interventioner för förebyggande av sexuellt överförbara infektioner bland ungdomar: En strukturerad litteraturstudie2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Sexual and reproductive health are fundamental to human well-being, both from physical, psychological, and social aspects. Research has shown that young people are one of the groups that pose the greatest risk of getting and spreading sexually transmitted infections (STI) which can lead to sexual and reproductive problems. STIs are problematic and can affect the sexual health of young people who are widely affected, even if there are increased opportunities to obtain information, available resources, and effective treatment options. This study considers it relevant to research STIs related to that group by using the salutogenic perspective.

    Purpose: The purpose of the study was to research and highlight sexual behaviors and attitudes that can lead to reduced risk of STI and to identify previous interventions or methods that have had positive effects on the prevention of STIs among young people between 15-24 years of age.

    Method: The method used was structured literature review. Qualitative and quantitative articles that had a publication date after the year 2013 were used. Thematic analysis was used to identifydifferent themes and collected data were analyzed deductively based on the salutogenic perspective.

    Conclusion: The results highlighted that specifically targeted sexual education in schools and specifically STI trained actors had positive effects on young people, which led toless risky behavior which also was STI-reducing. The results also showed that open communicationis an essential factor that contributes to young people´s attitudes about sex and the prevention of STIs.

    Att bära en osynlig börda: MRSA-bärarskap ur ett salutogent perspektiv2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Antibiotic resistance is a global problem and includes MRSA, methicillin-resistant Staphylococcus aureus. Reviews summarising important results concerning experiences of being colonised with MRSA are lacking. For efficient public health and infection prevention work, it is important to examine the experiences, resources, and strategies these individuals have regarding colonisation.

    Aim: To explore how individuals colonised with MRSA experienced this from a salutogenic perspective, based on Sense of Coherence (SOC), with respect to comprehensibility, manageability, and meaningfulness.

    Methods: A structured literary review was conducted where 10 scientific articles were analysed through thematic analysis from a salutogenic perspective.

    Results: Eleven subthemes were identified and related to three themes composed from the main components of SOC. “Comprehension” describes how the individual perceives their situation as colonised with MRSA and consists of the subthemes "Plague infected, dirty and invaded", "Shock, fear and shame", "Exclusion, loneliness and stigmatisation", "Ignorance, uncertainty and a mysterious threat" and "The present is disrupted, the future is affected". “Manageability” describes how the individual tries to manage the MRSA colonisation and consists of the subthemes "Protect others from infection", "Seek information" and "Inform and educate healthcare workers". “Meaningfulness” consists of the descriptions of what gives the commitment and motivation and consists of the subthemes "Take control over the situation", "Time, active learning and reflection" and "Good encounters and relationships".

    Conclusion: The experience of being colonised with MRSA often involves immense suffering for the affected individual. Living with MRSA is to exist on a continuum of salutogenesis/pathogenesis, where encounters and relationships with healthcare professionals play a key role in where the individual's health is positioned. There is an untapped salutogenic potential in healthcare professionals' encounters and interactions with MRSA carriers.

    Previous Experience Matters: An in-Person Investigation of Expectations in Human–Robot Interaction2024In: International Journal of Social Robotics, ISSN 1875-4791, E-ISSN 1875-4805Article in journal (Refereed)
    Abstract [en]

    The human–robot interaction (HRI) field goes beyond the mere technical aspects of developing robots, often investigating how humans perceive robots. Human perceptions and behavior are determined, in part, by expectations. Given the impact of expectations on behavior, it is important to understand what expectations individuals bring into HRI settings and how those expectations may affect their interactions with the robot over time. For many people, social robots are not a common part of their experiences, thus any expectations they have of social robots are likely shaped by other sources. As a result, individual expectations coming into HRI settings may be highly variable. Although there has been some recent interest in expectations within the field, there is an overall lack of empirical investigation into its impacts on HRI, especially in-person robot interactions. To this end, a within-subject in-person study () was performed where participants were instructed to engage in open conversation with the social robot Pepper during two 2.5 min sessions. The robot was equipped with a custom dialogue system based on the GPT-3 large language model, allowing autonomous responses to verbal input. Participants’ affective changes towards the robot were assessed using three questionnaires, NARS, RAS, commonly used in HRI studies, and Closeness, based on the IOS scale. In addition to the three standard questionnaires, a custom question was administered to capture participants’ views on robot capabilities. All measures were collected three times, before the interaction with the robot, after the first interaction with the robot, and after the second interaction with the robot. Results revealed that participants to large degrees stayed with the expectations they had coming into the study, and in contrast to our hypothesis, none of the measured scales moved towards a common mean. Moreover, previous experience with robots was revealed to be a major factor of how participants experienced the robot in the study. These results could be interpreted as implying that expectations of robots are to large degrees decided before interactions with the robot, and that these expectations do not necessarily change as a result of the interaction. Results reveal a strong connection to how expectations are studied in social psychology and human-human interaction, underpinning its relevance for HRI research.

    Multi-objective optimisation of a logistics area in the context of factory layout planning2024In: Production & Manufacturing Research, ISSN 2169-3277, Vol. 12, no 1, article id 2323484Article in journal (Refereed)
    Abstract [en]

    The manufacturing factory layout planning process is commonly supported by the use of digital tools, enabling creation and testing of potential layouts before being realised in the real world. The process relies on engineers’ experience and inputs from several cross-disciplinary functions, meaning that it is subjective, iterative and prone to errors and delays. To address this issue, new tools and methods are needed to make the planning process more objective, efficient and able to consider multiple objectives simultaneously. This work suggests and demonstrates a simulation-based multi-objective optimisation approach that assists the generation and assessment of factory layout proposals, where objectives and constraints related to safety regulations, workers’ well-being and walking distance are considered simultaneously. The paper illustrates how layout planning for a logistics area can become a cross-disciplinary and transparent activity, while being automated to a higher degree, providing objective results to facilitate informed decision-making.

    Faktorer som skapar bristande följsamhet till basal hygien: Sjuksköterskans upplevelse2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Although there is evidence for the hygiene routines that exist in Swedish hospitals, these routines are also failing. This leads, among other things, to high costs, suffering for patients and is a contributing factor to the development and spread of microorganisms with antibiotic resistance.

    Aim: The aim was to investigate which factors that nurses experienced contributed to the fact that there were deficiencies in adherence to basic hygiene.

    Method: Eight nurses who worked in inpatient care at a medium-sized Swedish hospital participated in semi-structured interviews. The empirical material was analyzed based on an interpretative phenomenological analysis (IPA), which was then supplemented with further categorization based on the Theory of Planned Behavior.

    Results: The results revealed nine factors that create a lack of compliance with basic hygiene, which were divided into four overarching themes: work environment, approach, competence and management. It emerged that the staff’s behavior regarding basic hygiene is influenced to the same extent by subjective as objective factors.

    Conclusion: Comprehensive routines and rules exist, but adherence to basic hygiene needs to be promoted. To succeed with this, interventions with greater focus on behavioral changes in staff are required. More research is needed to map how different factors influence behaviors around basic hygiene.

    Bioinformatics analysis on the drug supporting systems2023Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This research project investigates the interactions of staurosporine, a potent kinase inhibitor, with 11 ligands, highlighting its role in drug design and bioinformatics. Focusing on the selectivity and promiscuity of staurosporine in binding to protein kinases, the study employs the MANORAA database for data extraction. A Python script was developed to automate the retrieval and organisation of data, particularly targeting ligands with known affinity numbers. This method efficiently structures complex biochemical information into a comprehensible format. The research culminated in the creation of a website that presents detailed data on staurosporine’s molecular interactions and binding affinities. This website can serve as a valuable tool for researchers, offering insights into the drug's mechanism of action and its implications in therapeutic applications. The study methods included Python scripting for data handling and API integration for efficient data extraction, emphasising the importance of computational tools in bioinformatics. The findings reveal significant insights into the binding dynamics of staurosporine, identifying conserved and variable regions in kinase binding pockets that influence drug efficacy. These results contribute to a deeper understanding of staurosporine's broad spectrum of kinase inhibition and provide a model for future research in drug-protein interaction analysis. This project underscores the significance of accessible data presentation in bioinformatics, facilitating advanced research and development in drug design.

    Spelforskning i Sverige: LevelUp projektrapport2024Report (Other academic)
    Abstract [sv]

    Rapporten bygger på tre delstudier med olika datainsamlingstekniker:

    • En bibliometristudie av svensk spelforskning baserad på data från Scopus respektive SwePub.
    • En enkätstudie över svenska spelforskningsmiljöer.
    • En intervjustudie om svenska spelforskarmiljöer.

    Bibliometristudiens ansats har varit bred. Materialet inkluderar därmed även poster som endast har en perifer koppling till spel, men returnerar i fallet SwePub färre än 3000 poster. Spelforskning bedrivs på många lärosäten i Sverige och publiceras inom många ämnesområden. Totalt 95 forskare har en publicering som omfattar 10 eller fler spelpublikationer1. Det finns starka lokala kluster av forskare som sampublicerar men sampubliceringen mellan svenska och nordiska lärosäten är inte så omfattande. Jämfört med Finland har Sverige färre publikationer med ett tydligt fokus på spelforskning.

    Enkätstudien visar att spelforskarmiljöerna oftast består av ett antal forskare med olika ämnesmässig bakgrund där de själva definierar sig som spelforskare snarare än att organisationen som sådan gör det. Miljöerna har sammantaget och högt räknat runt 30 aktiva doktorander men siffran är osäker. 94% av respondenterna anger att deras forskning ligger inom ”spel för andra områden än underhållning” och endast 6% anger ”spelteknikfokus”. 44% anger ”spelbranschen”. Det är tydligt att spel för just underhållning inte ligger fokus för svensk spelforskning. Detta är remarkabelt då den svenska datorspelsindustrin är en multimiljardindustri fokuserad på just spel som underhållning. Det finns alltså en mycket stor diskrepans mellan industri och svensk spelforskning.

    Intervjustudien ger en bild av att spelforskningen bedrivs inom splittrade miljöer, av forskare med olika ämnesmässig bakgrund. Det finns en tydlig upplevd brist på forskningsfinansiering inom adekvata områden och det finns brister i de finansieringsinstrument som finns idag. Detta påverkar såväl vilken typ av forskning som kan bedrivas inom spel och rekryteringen av forskarstuderande. Respondenterna är överlag mycket positivt inställda till idén om en nationell forskarskola. Flera ser också Svenska Spelforskarrådet som en viktig aktör för att stärka svensk spelforskning både nationellt och internationellt.

    Rekommendationer:

    • Det bör finnas en tydligare egen hemvist för forskning och utbildning inom spel för att tydliggöra kärnan i området.
    • Fokus för forskningen behöver förändras så att spel för underhållning kommer mer i fokus.
    • Finansieringsinstrumenten för spelforskning behöver förändras för att möjliggöra en sådan förändring.
    • En nationell forskarskola inom spel bör inrättas.
    • Det finns anledning att lära av framgångsrika miljöer i Finland och Danmark.

    Perceiving agents: Pluralism, interaction, and existence2024Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Perception is a vast subject to study. One way to approach and study it might therefore be to break down the concept into smaller pieces. Specific modes of sensation, mechanisms, phenomena, or contexts might be selected as the proxy or starting point for addressing perception as a whole. Another approach would be to widen the concept, and attempt to study perception through the larger context of which it is a part. I have, in this thesis, attempted the latter strategy, by emphasising an existential perspective, and examine the role and nature of perception through that lens.

    The larger perspective of broadening the scope does not specifically allow for better answers, but rather different kinds of answers, providing complementary ways of exploring what it means to be an artificial or natural agent, and what consequences that can have for the access to, as well as representation, processing, and communication of information. A broader stance can also facilitate exploration of questions regarding larger perspectives, such as the relation between individual agents, as well as their place in larger structures such as societies and cyber-physical systems.

    In this thesis I use existential phenomenology to frame the concept of perception, while drawing from theories in biology and psychology. My work has a particular focus on human-robot interaction, a field of study at a fascinating intersection of humans designing, using, and communicating with something human-made, partially human-like, yet distinctly non-human. The work is also applied to some aspects of the traffic domain which, given the increasing interest in self-driving vehicles, is partially another instance of complex and naturalistic human-robot interaction.

    Ultimately, I argue for a pluralistic and pragmatic approach to the understanding of perception, and its related concepts. To understand a system of agents as they interact, it is not only necessary to acknowledge their respective circumstances, but take serious the idea that none of the agents’ constructed worlds are more or less real, they might only be more or less relevant in relation to specific contexts, perspectives, or needs. Such an approach is particularly relevant when addressing the complexities of the increasingly urgent sustainability challenges.

    Tillväxtkontroller i skolan, hur påverkas barn och ungdomar: En systematisk litteraturöversikt2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: In Sweden, health visits including height and weight measurements are one of the signature tasks for the school nurse. The school nurse as part of the school health staff aims to support children and adolescents to good health and a sense of coherence, SOC. This to offer students the best possible chances to good education in school. Height and weight measurements in schools as a screening program still lack evidence of what benefit it actually has for the individual.

    Purpose: The purpose is to describe how height and weight measurements in school affect children and adolescents.

    Results: This integrative literature review resulted in three categories; Feeling of discomfort, Focus on the body is elevated and Enhanced health awareness.

    Conclusion: Society's unattainable standards and ideals of beauty with a firm beauty culture contribute to the fact that screening our bodies become problematic. Deviating from the norm or being afraid of deviating from the norm can contribute to lowered self-esteem and self-image, which can affect the individuals’ experience of life and health in a life course perspective. It is therefore important that school health staff and school nurses work to support children and adolescents in their physical, psychological and social development. They also need to be aware of the importance to work with dismantle the dominant ideals of beauty because all children and adolescents have the right to experience good health and a sense of coherence.

    Review of Current Status and Future Directions for Collaborative and Semi-Automated Automotive Wire Harnesses Assembly2023In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 120, p. 696-701Article in journal (Refereed)
    Abstract [en]

    Wire harnesses are vital for any modern automotive vehicle. They control the basic functions in a vehicle, for example, windshield wipers and critical functions such as sensors, cameras, and autopilot functions. Thus, the quality of wire harness assembly is highly important. Today, wire harnesses are usually assembled manually, which creates unergonomic and tedious working conditions for operators. Traditional and collaborative industrial robots have been identified as possible solutions to overcome challenges faced by operators in this type of assembly. The international research community has proposed many solutions for automating the assembly of wire harnesses in automotive vehicles but despite these solutions, the industry has not been able to adopt a method to automate this assembly process fully or partially. This paper presents a review of findings on robot-assisted wire harness assembly processes based on a systematic literature review. Specifically, the assembly of wire harnesses in Electric Vehicles (EVs). The state-of-the-art review focuses on solutions to improve unergonomic work situations and ensure the quality of assembly operations. Best practices and reasons for the lack of extensive implementation in automotive final assembly systems are described. Further, the paper presents suggestions based on success stories where the automation of the wire harness assembly in automotive vehicles has been realised by leveraging human-centred automation solutions. Based on the findings, this paper identifies the research for future study. The findings also indicate that there is already technology that can support the automation of wire harness assembly processes in EVs but it is crucial to identify the human aspects and the role of humans in the assembly of wire harness assembly process.

    Viral simulations in dreams: The effect of the COVID-19 pandemic on threatening dream content in a Finnish sample of diary dreams2024In: Consciousness and Cognition, ISSN 1053-8100, E-ISSN 1090-2376, Vol. 119, article id 103651Article in journal (Refereed)
    Abstract [en]

    Previous research indicates that the COVID-19 pandemic has affected dreaming negatively. We compared 1132 dreams collected with prospective two-week dream diary during the pandemic to 166 dreams collected before the pandemic. We hypothesized that the pandemic would increase the number of threatening events, threats related to diseases, and the severity of threats. We also hypothesized that dreams that include direct references to the pandemic will include more threatening events, more disease-related threats, and more severe threats. In contradiction with our hypotheses, results showed no differences between pandemic and pre-pandemic samples in the number of threats, threats related to diseases, or severe threats. However, dreams with direct references to the pandemic had more threats, disease-related threats, and severe threats. Our results thus do not suggest a significant overall increase in nightmarish or threatening dream content during the pandemic but show a more profound effect on a minority of dreams.

    Security and Privacy of Online Record Access: A Survey of Adolescents' Views and Experiences in Sweden2024In: Journal of Adolescent Health, ISSN 1054-139X, E-ISSN 1879-1972Article in journal (Refereed)
    Abstract [en]

    Purpose: Ensuring security of online health records and patients' perceptions of security are concerns in adolescent healthcare. Little is known about adolescents' perceptions about healthcare's ability to protect online health records. This article explores adolescents' perspectives on security and privacy of their online health records, potential differences based on gender and health, attitudes to sharing information, and perceptions of what constitutes sensitive information. Methods: This study included a subset of items from a national online patient survey conducted in Sweden (January-February 2022), focusing on respondents aged 15–19 years. Gender and health status differences were calculated using the Kruskal-Wallis test. Results: Of 218 adolescent respondents (77.1% female), a minority had security and privacy concerns. A notable proportion (41.3%) wished to control who could see their records, and those who reported better perceived health were more likely to want to manage access to their electronic health record (H = 13.569, p = .009). Most had not experienced unauthorized access to their records (75.2%) and had never shared health information on other online applications (85.8%). More than half (56.0%) perceived some information as sensitive, where mental health was the most common (76.0%). Most felt that reading their notes improved their trust for their healthcare professional (65.6%) and supported better communication with healthcare professionals (66.5%). Discussion: In this national survey, adolescents generally reported few concerns about patient portals. Findings emphasize the need for security and privacy protection and to empower adolescents with greater control over access to their health information housed in electronic health record systems.

    Surface Defect Detection with Limited Training Data: A Case Study on Crown Wheel Surface Inspection2023In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 120, p. 1333-1338Article in journal (Refereed)
    Abstract [en]

    This paper presents an approach to automatic surface defect detection by a deep learning-based object detection method, particularly in challenging scenarios where defects are rare, i.e., with limited training data. We base our approach on an object detection model YOLOv8, preceded by a few steps: 1) filtering out irrelevant information, 2) enhancing the visibility of defects, namely brightness contrast, and 3) increasing the diversity of the training data through data augmentation. We evaluated the method in an industrial case study of crown wheel surface inspection in detecting Unclean Gear as well as Deburring defects, resulting in promising performances. With the combination of the three preprocessing steps, we improved the detection accuracy by 22.2% and 37.5% respectively while detecting those two defects. We believe that the proposed approach is also adaptable to various applications of surface defect detection in other industrial environments as the employed techniques, such as image segmentation, are available off the shelf.

    Augmented reality for machine monitoring in industrial manufacturing: framework and application development2023In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, p. 1327-1332Article in journal (Refereed)
    Abstract [en]

    Enhancing data visualization on the shop floor provides support for dealing with the increasing complexity of production and the need for progressing towards emerging goals like energy efficiency. It enables personnel to make informed decisions based on real-time data displayed on user-friendly interfaces. Augmented reality (AR) technology provides a promising solution to this problem by allowing for the visualization of data in a more immersive and interactive way. The aim of this study is to present a framework to visualize live and historic data about energy consumption in AR, using Power BI and Unity, and discuss the applications' capabilities. The study demonstrated that both Power BI and Unity can effectively visualize near-real-time machine data with the aid of appropriate data pipelines. While both applications have their respective strengths and limitations, they can support informed decision-making and proactive measures to improve energy utilization. Additional research is needed to examine the correlation between energy consumption and production dynamics, as well as to assess the user-friendliness of the data presentation for effective decision-making support.

    ”Man vill ju inte ha ihjäl en patient”: Vårdpersonals attityder till basala hygienrutiner vid blodkomponentframställning2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Within healthcare, there are many laws and regulations that must be followed, not least regarding work close to patients and handling of equipment to reduce the risk of healthcare-related infections. The caregiver plays a major role in following regulations and laws to provide the patient with good, safe and equal care. The consequences of not following basic hygiene routines when producing blood components can result in the patient receiving the blood product having a transfusion reaction.

    Aim: The aim of the study was to study attitudes towards basic hygiene routines in health care professionals who work with blood component production.

    Method: A qualitative semi-structured interview study was conducted. Six informants participated in the interviews and answered eleven questions. The informants worked at a blood center and participation was voluntary after the informants gave verbal consent. The content of the interviews was then analyzed using thematic content analysis with an inductive approach.

    Results: Four themes could be identified "Attitudes and awareness towards basic hygiene routines", "Value linked to compliance with basic hygiene routines", "Enforcement of adherence to basic hygiene routines within the work group" and "Prerequisites for correct compliance with basic hygiene routines". The results showed a positive attitude towards basic hygiene routines.

    Conclusion: The themes that were developed represent different aspects of basic hygiene routines; the personal attitude and awareness, the value of compliance with basic hygiene routines, what contributes to adherence to basic hygiene routines in the work group and the conditions required to be able to perform basic hygiene routines correctly.

    Sjuksköterskors attityder till patientmedverkan i att förebygga vårdrelaterade infektioner: En kvalitativ intervjustudie2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Healthcare associated infections (HAI), are a threat to public health, both nationally and globally, due to the burden of affected patients, relatives, various parts of the healthcare system and the increasing effect it has on antimicrobial resistance, as HAI often require antibiotic treatment. HAIs are prevented by infection-prevention and control on all levels of the healthcare system including participating patients and relatives. Patient-participation in the prevention of HAI is an underused and underexplored area, where registered nurses can play a vital role as an expert in nursing care in so called partnership with the patient.

    Aim: The aim was to explore attitudes among nurses towards patient-participation in the prevention of HAI.

    Methods: Data collection was made by semistructured individual interviews with eight registered nurses, working in hospital inpatient care. The method for analysis was qualitative content analysis with an inductive approach.

    Results: Eleven subcategories, three categories and one all-embracing theme emerged. The categories were ”Patient-participation is positive”, ”The healthcare-system needs to invite patients” and ”Patients needs to come onboard”. The theme was ”Important topic, depending on the partnership caregiver-patient, in need of development and to be concretizised.”

    Conclusion: The attitudes among nurses towards patient-participation in preventing HAI includes that HAI represents a serious, real and present health-threath. Patient-participation in the prevention of HAI was perceived as a positive and potentially gainful phenomenon, depending on the caregiver-patient partnership. The topic needs to be noticed, concretized and elaborated in order to become a self-evident part of a person-centered, equal healthcare.

    ”It´s like walking in a bubble”, nursing students´ perspectives on age suit simulation in a home environment – group interviews from reflection seminars2024In: BMC Nursing, E-ISSN 1472-6955, Vol. 23, no 1, article id 124Article in journal (Refereed)
    Abstract [en]

    Background

    Older persons with age-related and complex health problems will increasingly depend on care provision from nurses in their own homes. However, a barrier to quality care is ageism and nursing students´ disinterest in geriatrics. In addition, nurse education often falls short in preparing students for the complexity of geriatric care. Welfare technology (WT) is progressively implemented in home care to help older persons live at home despite their health problems. However, this process is intricate and requires acceptance and digital literacy among caregivers and older persons. Despite these challenges, nurse education can address and change negative attitudes through innovative teaching methods such as age suit simulation. Therefore, the study aims to describe nursing students´ experiences of age suit simulation in a home-like environment with WT and technical aids, and will reveal their perspective on ageing and providing care to older adults.

    Methods

    A qualitative explorative design using semi-structured group interviews (n=39) among nursing students. Data was analysed through reflexive thematic analysis.

    Results

    The analysis generated three main themes; “It’s like walking in a bubble”, “An eye opener” and “Concerns about ageing and the current structure of geriatric care”. The main themes included eight subthemes. Adapting to the sensory and physical limitations of the age suit was an immersive experience and caused feelings of frustration, loneliness and disconnection. A prominent result was a raised awareness of cognitive loss, especially impaired vision, and students felt the simulations had made them aware of the everyday challenges older persons faced. Students highlighted the importance of patience and giving enough time in care situations by being present and having a critical perspective of WT. The students were mostly negative towards their own ageing and could better relate to older persons´ vulnerability.

    Conclusions

    Age suit simulation was described as an embodied and eye-opening experience, raising nursing students´ awareness of older persons´ functional limitations and the consequences for dignity and independence. Coping with cognitive loss was especially difficult. Students were motivated to apply their new knowledge to clinical practice. Age suit simulation can complement geriatric education, preparing students for the complex care needs of older persons.

    Påverkansfaktorer för PVK-relaterade infektioner: En systematisk litteraturöversikt med kvalitativ ansats2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Healthcare-associated infections, HAI’s, are a major health problem in Sweden. By preventing the avoidable infections that affect patients in our hospitals, we could free up to 200,000 care days and 2.2 billion SEK yearly. PVC’s account for an unclear proportion of these infections.

    Aim: The aim of the study was to investigate which factors may affect the occurrence of PVC-related infections.

    Method: a systematic literature review with a qualitative approach. Original studies that responded to the purpose of the study were searched in the data-bases Cinahl and Pubmed, with criteria that they should have been published in the last 10 years. Narrative analysis in the form of concentration and categorization of the results with a compilation in text.

    Results: Twelve studies were included in the review. The main findings can be summarized as that chlorhexidine alcohol is better than povidone-iodine, injection membranes need to be disinfected to be recommended, heparin is not better than sodium chloride for preventing complications, the choice of dressing does not affect the occurrence of compli-cations and that PVC’s should be changed on clinical indication.

    Conclusion: What is consistently highlighted in the included studies is that there is a lack of evidence to determine the occurrence of PVC-related bacteraemia. This literature review shows that in order to reduce PVC-related infections, chlorhexidine alcohol should be used as a disinfectant and that PVC’s are to be changed on clinical indication. What has clearly emerged is that PVC-related infections are an understudied topic, large studies are needed that measure the occurrence of the infections in order to then be able to measure the effect of various interventions with further studies.

    Kan det oförberedda förberedas?: En kvalitativ intervjustudie av anestesisjuksköterskors upplevelser av traumalarm nivå 12023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Trauma is the leading primary cause of death for individuals up to 44 years old in Sweden, underscoring the need for advanced trauma care. Nurse anaesthetists play a crucial role in hospital trauma alerts. When trauma patients arrive, specialized teams are mobilized following specific protocols. For level 1 trauma alerts, indicating severe cases, nurse anaesthetists work with anaesthesiologists, leaving their regular operating room duties for emergency department conditions.

    Purpose: This study investigates nurse anaesthetists’ experiences with level 1 trauma alerts.

    Method: Data were gathered from qualitative semi-structured interviews with ten hospital staff members working at the same hospital. A qualitative content analysis was conducted.

    Results: The analysis yielded nine subcategories and three main categories: prerequisites for safe trauma care, stress during trauma alerts, and emotional aspects of trauma alerts. From these categories a theme emerged: can the unprepared be prepared?

    Conclusion: Effective communication is vital during trauma alerts, and successful outcomes are often aided by strong leadership. Nurse anaesthetists experience emotional responses before, during, and after trauma alerts, with notable emotional impacts following the resolution of the situation.

    Kvinnors upplevelser av att genomgå en hysterektomi: En kvalitativ litteraurstudie2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: A hysterectomy means that the woman’s uterus is surgically removed and is one of the most common gynecological surgeries. Indications for the procedure are usually benign bleeding disorders, fibroids, endometriosis, prolapse and malignant gynecological conditions. These conditions cause a great suffering for the women and the nurse need to consider both physical and psychological aspects in nursing to be able to increase the women's well-being and quality of life.

    Aim: To describe women's experiences of undergoing a hysterectomy.

    Method: Qualitative literature review based on ten scientific articles. The databases used were CINAHL, Medline and Pubmed. A thematic analysis was done in four steps.

    Findings: Five themes emerged in the results; limited by a changed body, need for support, a well-functioning care, care without person-centeredness and an affected quality of life after the operation.

    Conclusion: Before their hysterectomy, women experienced a loss of their own body as it no longer functioned as before. This led to a loss of their identity and affected their everyday lives. The women needed comprehensible information and support from both healthcare professionals and their surroundings. Specialized care was seen as well-functioning, but the women lacked person-centered care.

    Numerical and experimental study of the variation of keyhole depth with an aluminum alloy (AA1050)2024In: Journal of Advanced Joining Processes, E-ISSN 2666-3309, Vol. 9, article id 100196Article in journal (Refereed)
    Abstract [en]

    The keyhole depth is a key measurement characteristic in the laser welding of busbar to battery tabs in battery packs for electric vehicles (EV), as it directly affects the quality of the weld. In this work, experiments are carried out with controlled and adjusted laser power and feed rate parameters to investigate the influence on the keyhole width, keyhole depth and porosities. A 3D numerical model of laser keyhole welding of an aluminum alloy (A1050) has been developed to describe the porosity formation and the keyhole depth variation. A new integration model of the recoil pressure and the rate of evaporation model is implemented which is closer to the natural phenomena as compared to the conventional methods. Additionally, major physical forces are employed including plume formation, upward vapor pressure and multiple reflection in the keyhole. The results show that keyhole depth is lower at higher feed rate, while lower feed rates result in increased keyhole depth. This study reveals that low energy densities result in an unstable keyhole with high spattering, exacerbated by increased laser power. Mitigating incomplete fusion is achieved by elevating laser energy density. The findings emphasize the critical role of keyhole depth in optimizing laser welding processes for applications like busbar-to-battery tab welding.

    Mathematical modelling simulation data and artificial intelligence for the study of tumour-macrophage interaction2023Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The study explores the integration of mathematical modelling and machine learning to understand tumour-macrophage interactions in the tumour microenvironment. It details mathematical models based on biochemistry and physics for predicting tumour dynamics, highlighting the role of macrophages. Machine learning, particularly unsupervised and supervised techniques like K-means clustering, logistic regression, and support vector machines, are implemented to analyse simulation data. The thesis's integration of K-means clustering reveals distinct tumour behaviour patterns through the classification of tumour cells based on their microenvironmental interactions. This segmentation is crucial for understanding tumour heterogeneity and its implications for treatment. Additionally, the application of logistic regression provides insights into the probability of macrophage polarization states in the tumour microenvironment. This statistical model underscores the significant factors influencing macrophage behaviour and their consequent impact on tumour progression. These analytical approaches enhance the understanding of the complex dynamics within the tumour microenvironment, contributing to more effective tumour study strategies. The study presents a comprehensive analysis of tumour growth, macrophage polarization, and their impact on cancer treatment and prognosis. Ethical considerations and future directions focus on enhancing model accuracy and integrating experimental data for improved cancer diagnosis and treatment strategies. The thesis concludes with the potential of this hybrid approach in advancing cancer biology and therapeutic approaches.

    Computational detection of human papilloma virus in the cervical cancer genome2023Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Global research and development have witnessed new horizons in technological advancements, especially in the use of new-generation bioinformatic tools to solve human needs. Cervical cancer, caused by a sexually transmitted virus like human papillomavirus (HPV), is one of the most common cancers threatening women's health. The main aim of the study is to evaluate existing Next-generation pipelines for detection of HPV in cervical cancer. The method includes data retrieval, which involves careful selection and downloading of 30 metagenomic data (in FASTA-Q format) from the Human Microbiome Project database. The implementation phase of the study involved setting up and configuring the virus detection tools (HPViewer, VirusSeq and VirusFinder 2.0). All the tools were run on default settings to analyze the metagenome samples using the instructions provided by their authors. The result showed that the tools detected HPV. The HPViewer demonstrated a higher level of HPV detection, followed by VirusSeq and then VirusFinder 2. The HPViewer had the shortest run time, completing an analysis in 24.1 seconds, followed by VirusFinder 2 in 208 seconds and VirusSeq took 4200 seconds (1 hour, 10 minutes to run). HPViewer demonstrated an outstanding sensitivity of 100%, VirusFinder 2 (45.5 %) and VirusSeq (63.6%). In conclusion, the present study underscored the trade-offs between speed, accuracy, and resource consumption between bioinformatics tools for HPV detection. Each of the tools exhibited unique strengths and limitations; however, they provided valuable options for HPV detection.

    Truck-to-door sequencing in multi-door cross-docking system with dock repeat truck holding patter2020In: International Journal of Industrial Engineering Computations, ISSN 1923-2926, E-ISSN 1923-2934, Vol. 11, no 2, p. 201-220Article in journal (Refereed)
    Abstract [en]

    Cross-docking is a logistics strategy that consolidates the products of different inbound trucks according to their destinations in order to reduce the inventory, order picking, and transportation costs. It requires a high level of collaboration between inbound trucks, internal operations, and outbound trucks. This article addresses the truck-to-door sequencing problem. Truck-to-door sequencing has been studied by some researchers in different titles such as scheduling and sequencing of inbound and outbound trucks of the cross-dock center. However, previous studies have not considered repeat truck holding pattern. Therefore, it is important to determine the doors and the sequence of the inbound and outbound trucks that should be assigned in a cross-dock center. This paper focuses on optimizing truck-to-door sequencing with consideration of repeat truck holding pattern in inbound trucks in order to minimize makespan. Two methods are considered to solve this problem, including mathematical modeling and a heuristic algorithm. In the first method, a mixed integer-programming model is developed to minimize the makespan. Then, GAMS software is used to solve small-scale problems. In the second approach, a heuristic algorithm is developed to find near-optimal solutions within the shortest time possible and the algorithm is used to solve large-scale problems. The results of the mathematical model and the heuristic algorithm are slightly different and show the good quality of the presented heuristic algorithm.

    Single machine batch processing problem with release dates to minimize total completion time2018In: International Journal of Industrial Engineering Computations, ISSN 1923-2926, E-ISSN 1923-2934, Vol. 9, no 3, p. 331-348Article in journal (Refereed)
    Abstract [en]

    A single machine batch processing problem with release dates to minimize the total completion time (1|rj,batch|∑Cj ) is investigated in this research. An original mixed integer linear programming (MILP) model is proposed to optimally solve the problem. Since the research problem at hand is shown to be NP-hard, several different meta-heuristic algorithms based on tabu search (TS) and particle swarm optimization (PSO) are used to solve the problem. To find the most performing heuristic optimization technique, a set of test cases ranging in size (small, medium, and large) are randomly generated and solved by the proposed meta-heuristic algorithms. An extended comparison analysis is carried out and the outperformance of a hybrid meta-heuristic technique properly combining PSO and genetic algorithm (PSO-GA) is statistically demonstrated.

    Analys av grön infrastruktur för barrnaturskog inom projektområde för planerad vindpark vid Trollugnsberget2023Report (Other academic)
    Abstract [sv]

    Rapporten presenterar och redovisar ett kunskapsunderlag om förutsättningar för biologisk mångfald knuten till barrnaturskog inom och i närområdet av projektområde för vindkraftspark Trollugnsberget i Smedjebackens kommun. Utifrån underlaget kan OX2 prioritera markanvändning och arbeta för att bibehålla och utveckla en grön infrastruktur som bidrar till att uppfylla miljökvalitetsmålen Ett rikt växt- och djurliv samt Levande skogar.

    Kunskapsunderlaget har tagits fram med en ny metod benämnt Biotope Biodiversity Capacity Indicator (BBCI). BBCI är en indikator som uppskattar ett biotoplandskaps förmåga att hålla biologisk mångfald. Metodutveckling har finansierats av Naturvårdsverkets miljöforskningsanslag och framtagning av det specifika underlaget och analyserna i rapporten har finansierats av OX2.

    BBCI bygger på ekologisk kunskap om hur landskapets struktur påverkar arters överlevnad och biologisk mångfald. Med hjälp av indikatorn kan man undersöka om i) landskapet som helhet är hållbart ur ett biologiskt mångfaldsperspektiv, ii) hur många och vilka patcher1 som inte är hållbara i sig själva och iii) hur känsligt landskapets biologiska mångfald är för negativ påverkan på specifika patcher och var en förstärkning skulle kunna göra störst nytta.

    BBCI har beräknats för barrnaturskog som finns inom projektområdet för vindparken samt i dess närhet. Som underlag och indata till biotoplandskapens struktur användes data från genomförd naturvärdesinventering samt från skogsbolagens nyckelbiotopsklassificering. I rapporten redovisas barrnaturskogens långsiktiga hållbarhet för biologisk mångfald och dess känslighet för tidsperspektivet 100 år. Beräkningar har gjorts utifrån två olika fokusarter2 där fokusart 1 har mindre arealkrav jämfört med fokusart 2. Resultaten visar att befintliga förekomster av barrnaturskog inte är hållbara i ett 100-årsperspektiv, varken för fokusart 1 eller 2. Åtgärder som stärker barrnaturskogens förutsättningar att hålla biologisk mångfald är därför att rekommendera.

    1 Patcher kallas de fragment eller avgränsade ytor som finns i landskapet och som består av den biotop som studeras. En patch är ett avgränsat fragment av biotopen som omges av andra typer av livsmiljöer än den som biotopen består av.

    2 BBCI bygger på modellering av fokusarter. En fokusarts möjlighet att fortleva i landskapet indikerar även att många andra arter, som är en del av det ekosystem fokusarten representerar, också kan fortleva i landskapet och därmed biologisk mångfald.

    Perioperativ hypotermi: En undersökning av förekomsten hos dagkirurgiska patienter2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: There are many factors that put the patient in unintentional hypothermia during surgery. Already during the first hour, the body temperature can drop by 0.3–1°C due to anesthetic agents and conditions inside the operating room. The consequences are impaired wound healing, greater risk of wound infection, prolonged treatment time and discomfort for the patient. The anesthetic and surgical nurse have a common task to prevent and identify the onset of hypothermia.

    Aim: To investigate the occurrence, correlations and risk factors for inadvertent hypothermia perioperatively.

    Method: An empirical study with a quantitative, longitudinal, prospective approach. The number of forms that were collected on a day surgery department was 224 and these were analyzed descriptively and analytically.

    Results: The results show that hypothermia occurred on 30.4% of the patients and is most common in time of handover to the postoperative department. A quarter of the patients felt cold during the time of care and they are found to be significantly colder than those who answered no to that question. Temperature decreases significantly with increasing age. The most important riskfactor for suffering from hypothermia is low temperature on arrival.

    Conclusion: This study has provided increased knowledge about the occurrence, association and risk factors of hypothermia. A third of the patients where hypothermic, which shows that there is room for improvement. The patient's temperature on arrival was found to be of great importance for the patient's continued temperature in the perioperative course. Awareness of the results in the studies can help to improve patient comfort and reduce the risk of complications.

    From games to news: Creating an engagement model for digital local news2024Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The transition of local news from the analog, printed format to a digital format, fit for our increasingly digitized media technology society, has not been as straight-forward as was imagined at the dawning of the World Wide Web. Newspapers, in particular local newspapers, were quite fast in trying to adapt to the new technology platform and put their content on the web. User experiences of reading news have certainly evolved since 1995, with the introduction, for example, of the smartphone and proprietary news apps. However, there has been no deep or consistent commitment to understanding more specifically how the digital format can provide a means of interactivity for users and support a range of content and means to engage it. The digital news format does enable interaction between readers and news staff, and, not least, between users in real-time. However, many features for engagement are currently under-explored. Other media, for example computer games, have developed new ways to engage their audience of players both in terms of how the media is distributed and also how the content is personally adaptive, for example, to the unique skill level of players, or by offering them freedom of action to explore content, and/or by enabling increasing communication among player groups.

    The main knowledge contribution of this research is a novel model for reader engagement in digital local news. The model is constructed by transferring features for user needs satisfaction and engagement in digital games to the realm of digital local news. Self Determination Theory, which establishes ways of describing user engagement in general, and when applied to computer games specifically, forms the basis of the research. Additionally detailed knowledge about user types counters a traditional ‘one to many’ broadcast logic and supports greater understanding of heterogeneity within reader groups. The model also defines the digital maturity of the different features across a spectrum, from substitution via modification to disruption (Su-Mo-Di). For example, some digital features replicate those from the analog printed version II of the newspaper (substitution), while some are impossible to implement in a paper format (disruption).

    The aim of the research is to outline a unique model of engagement and illustrate how to apply the varied and detailed features when applied to digital local news. This usage of game engagement transferred to digital news contexts also allows alternative ways to interpret the term gamification. Classically gamification has been defined as using game design elements in non-game contexts, where typical game features like points, leaderboards, and badges have been introduced into a significant variation of media and forms, often to increase effectiveness or output from processes. This research contests that view and suggests that gamification can be used to engage mechanisms from games on a higher or more abstract level than actual game mechanics.

    The method for transferring this form of game engagement to digital local news engagement is built on a process where the more detailed strategies for making computer games engaging are abstracted and re-applied to the field of digital local news. These strategies form the basis for the unique engagement model illustrated within the thesis. These engagement aspects drawn from the model are further elaborated and used to examine specific examples and two prototypes focused on digital local news. The conclusions demonstrate that a focus on engagement through many varied applications can offer a rich method to increase and to analyze user experiences and to design novel features specific to enhancing digital local news.

    Identification of biomarker candidates for exfoliative glaucoma from autoimmunity profiling2024In: BMC Ophthalmology, E-ISSN 1471-2415, Vol. 24, no 1, article id 44Article in journal (Refereed)
    Abstract [en]

    Background: Exfoliative glaucoma (XFG) is a subtype of open-angle glaucoma characterized by distinctive extracellular fibrils and a yet unknown pathogenesis potentially involving immune-related factors. The aim of this exploratory study was to identify biomarkers for XFG using data from autoimmunity profiling performed on blood samples from a Scandinavian cohort of patients. Methods: Autoantibody screening was analyzed against 258 different protein fragments in blood samples taken from 30 patients diagnosed with XFG and 30 healthy donors. The 258 protein fragments were selected based on a preliminary study performed on 3072 randomly selected antigens and antigens associated with the eye. The “limma” package was used to perform moderated t-tests on the proteomic data to identify differentially expressed reactivity between the groups. Results: Multiple associated genes were highlighted as possible biomarker candidates including FUT2, CDH5, and the LOX family genes. Using seven variables, our binary logistic regression model was able to classify the cases from the controls with an AUC of 0.85, and our reduced model using only one variable corresponding to the FUT2 gene provided an AUC of 0.75, based on LOOCV. Furthermore, over-representation gene analysis was performed to identify pathways that were associated with antigens differentially bound to self-antibodies. This highlighted the enrichment of pathways related to collagen fibril formation and the regulatory molecules mir-3176 and mir-876-5p. Conclusions: This study suggests several potential biomarkers that may be useful in developing further models of the pathology of XFG. In particular, CDH5, FUT2, and the LOX family seem to have a relationship which merits additional exploration.

    Adolescents' and Young Adults' Experiences of Offense from Reading Their Health Records Online2024In: Studies in Health Technology and Informatics, ISSN 0926-9630, E-ISSN 1879-8365, Vol. 310, p. 1422-1423Article in journal (Refereed)
    Abstract [en]

    Patients feeling offended by reading records online is a concern among healthcare professionals, however previously published work has focused on adult patients. Here, a survey was used to explore and compare experiences of offense among adolescents (15-19 years old) and young adults (20-24 years old). Findings indicated that while the ratio of those offended did not differ between adolescents and young adults, reasons for feeling offended did.

    Intensivvårdssjuksköterskors erfarenheter av brytpunktssamtal: En kvalitativ intervjustudie2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: During 2022 circa 42 200 patients were treated in ICU’s in Sweden. Eight % of those treated deceased in ICUs. This means, ICU nurses encounter patients and relatives in a difficult time. Breakpoint conversations are guaranteed occurances for these nurses. This in turn requires the nurses to be prepared to respond appropriately to feelings of patients and relatives, when the decision to end treatment is taken. Aim: The aim of this study was to investigate nurses’ experiences of breakpoint conversations. Method: A qualitative study where nurses were interviewed in focus groups. The resulting material was analyzed with a qualitative content analysis. Results: Five categories were highlighted; ”When care changes direction”, ”To be comfortable in the profession”, ”Cooperation in the professional team”, ”The art of conveying information” and ”Allowing space for time and emotions”. For the nurses, the words breakpoint conversation, implies giving tough information to patients and relatives. Dedicating time to answering questions, cooperation between professions and lack of resources were highlighted in the results. Conclusion: Breakpoint conversations affects all who are involved, both patient, relatives and health-care professionals. Nurses have an impactful role in ho breakpoint conversations are formed and received. Understanding one’s role in breakpoint conversations is a necessity in encountering patients and relatives in a difficult situation.

    Symtomskattning i kombination med bedömningsinstrument inom palliativ vård vid kognitiv sjukdom: En kvalitativ studie inom kommunal hemsjukvård ur ett sjuksköterskeperspektiv2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Many older adults with cognitive impairment and palliative care needs either live at home or are cared for in nursing homes. In order to obtain a comprehensive understanding of the older adults symptoms, nurses can utilize various assessment tools. Several symptom assessment tools are available to evaluate symptoms, both general and specific, within palliative care. Unfortunately, many of these tools are not suitable for use with individuals with reduced cognitive abilities. Aim: The purpose of the study is to illuminate nurses' experiences of symptom assessment in combination with assessment tools in palliative care for individuals with cognitive disorders within municipal home healthcare. Method: A qualitative method with an inductive approach was employed. Data collection was conducted through qualitative surveys with open-ended questions. Findings: The results are presented in two overarching categories: Symptom Assessment and Opportunities and Challenges in Symptom Assessment. The findings indicate that symptom assessment using assessment instruments varies, and collaboration in a team with the patient, family, and other professionals is considered essential to ensure high-quality and safe palliative care for individuals with cognitive disease. Conclusion: Symptom assessment should not be regarded merely as a standardized process but rather as a complex and individualized evaluation task that requires various strategies based on the patient's needs and situation.

    Abstract [en]

    Background: Anesthesia- and operating nurses´ will encounter patients with some form of cognitive impairment during their work. Perioperative specialist nurses have a duty to provide individualized care for patients with cognitive impairment. The perioperative dialogue is a way for patients and their relatives to understand the health situation, and for specialist nurses, it serves as a tool to gather adequate information about the patient's preferences. Aim: The aim was to describe the experiences of anesthesia- and operating nurses´ in caring for patients with cognitive impairment within perioperative care. Method: A qualitative method with an inductive approach was used in the study. Six anesthesia nurses and four surgical nurses were interviewed, and the collected material was analyzed using qualitative content analysis. Results: The analysis process resulted in three categories: "team collaboration", "need for resources and aids" and "need for individualized approach and communication", along with 14 subcategories. Conclusion: The study revealed that caring for patients with cognitive impairment in the perioperative environment posed a challenge. The perioperative care can be adapted to the patient's specific needs through the involvement of close relatives, professional teamwork, and a person-centered approach.

    Examination of pathway crosstalk and functional modules in papillary thyroid cancer dedifferentiation to anaplastic thyroid cancer2023Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Thyroid cancer, comprising well-differentiated follicular and papillary types, alongside less common medullary and anaplastic subtypes with poor prognoses, exhibits specific anaplastic cases resulting from papillary dedifferentiation, lacking precise molecular evidence. Utilizing Metascape, CTpathway and PathwAX II, the study integrates functional modules and pathway crosstalk for dedifferentiation analysis, conducting a comprehensive two-dimensional assessment of toolset’s functionality, compatibility, and interoperability. Results suggest that transitions between the cancer subtypes involve pathways related to cellular processes, extracellular matrix interactions, and genetic alterations. Metascape enriched crosstalk tool findings, providing extended lists of specific pathways, while CTpathway exhibited better sensitivity and specificity, offering more result customization options and database selection than PathwAX II. PathwAX II, with unique interactive features for network display and identifying depleted pathways, emerges a valuable component in a comprehensive pipeline integrating these three tools. Additional validation against previous clinical studies affirms the reliability of the results, reinforcing PathwAX II’s role as a key reference point in the creation of such a pipeline. The study also suggests future tool development directions, highlighting strengths and limitations across the platforms. The detailed pathway and gene analysis contributes concrete knowledge to the scientific community, serving as a hallmark for future studies.

    Guld och gröna skogar: En analys av värdefull ekmiljö i Stockholms län2023Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Oak (Quercus spp.) is of great national importance for biodiversity, as central and fundamental components of local ecosystems. Stockholm County is one of Sweden's most densely populated regions where rapid urban densification and high rates of exploitation pose a real threat to valuable oak habitats. The purpose of the study is to investigate variables that define valuable oak habitats, and through GIS analysis locate their distribution in Stockholm County. Furthermore, the study examines whether there is a positive relationship between parameters associated with oak habitats, biodiversity, and the size of value areas. Through literature review, 18 parameters suitable for identifying and ranking valuable oak habitats were noted. A scoring system was developed to assess oak attributes as an indirect measure of biodiversity. The system provides a relatively accessible identification of valuable oak habitats across three scales: elements with high conservation value (Swedish: värdeelement), valuable core areas (Swedish: värdekärnor), and value areas at landscape scale (Swedish: värdetrakt). Cluster analyses based on four dispersal distances, 119, 200, 477 and 656 meters were conducted to locate valuable core areas. Moreover, a buffer analysis based on a two-kilometer dispersal distance, identified 20 value areas at landscape scale in Stockholm County. These 172 valuable core areas and 20 value areas were then ranked based on the mean scores of the oak trees. Spearman's correlation analysis was performed to examine whether there was a positive correlation between the size of the valuable core areas or value areas and biodiversity, with no positive correlation found. The findings of the study suggest that high nature values are not synonymous with large valuable core areas or value areas, and that small valuable core areas and value areas also can be of great importance.

    Breaking barriers: a statistical and machine learning-based hybrid system for predicting dementia2023In: Frontiers in Bioengineering and Biotechnology, E-ISSN 2296-4185, Vol. 11, article id 1336255Article in journal (Refereed)
    Abstract [en]

    Introduction: Dementia is a condition (a collection of related signs and symptoms) that causes a continuing deterioration in cognitive function, and millions of people are impacted by dementia every year as the world population continues to rise. Conventional approaches for determining dementia rely primarily on clinical examinations, analyzing medical records, and administering cognitive and neuropsychological testing. However, these methods are time-consuming and costly in terms of treatment. Therefore, this study aims to present a noninvasive method for the early prediction of dementia so that preventive steps should be taken to avoid dementia. Methods: We developed a hybrid diagnostic system based on statistical and machine learning (ML) methods that used patient electronic health records to predict dementia. The dataset used for this study was obtained from the Swedish National Study on Aging and Care (SNAC), with a sample size of 43040 and 75 features. The newly constructed diagnostic extracts a subset of useful features from the dataset through a statistical method (F-score). For the classification, we developed an ensemble voting classifier based on five different ML models: decision tree (DT), naive Bayes (NB), logistic regression (LR), support vector machines (SVM), and random forest (RF). To address the problem of ML model overfitting, we used a cross-validation approach to evaluate the performance of the proposed diagnostic system. Various assessment measures, such as accuracy, sensitivity, specificity, receiver operating characteristic (ROC) curve, and Matthew’s correlation coefficient (MCC), were used to thoroughly validate the devised diagnostic system’s efficiency. Results: According to the experimental results, the proposed diagnostic method achieved the best accuracy of 98.25%, as well as sensitivity of 97.44%, specificity of 95.744%, and MCC of 0.7535. Discussion: The effectiveness of the proposed diagnostic approach is compared to various cutting-edge feature selection techniques and baseline ML models. From experimental results, it is evident that the proposed diagnostic system outperformed the prior feature selection strategies and baseline ML models regarding accuracy.
