    Optimizing the yield and physico-chemical properties of pine cone cellulose nanocrystals by different hydrolysis time2018In: Cellulose (London), ISSN 0969-0239, E-ISSN 1572-882X, Vol. 25, no 5, p. 2925-2938Article in journal (Refereed)
    Abstract [en]

    Cellulose nanocrystals (CNCs) were isolated for the first time from pine cones (PC) by alkali and bleaching treatments and subsequent sulfuric acid hydrolysis (64%) at 45 degrees C. The influence of the hydrolytic reaction time (30, 45, and 90 min) on the yield, chemical composition and structure, and thermal stability of CNCs was evaluated. The removal of non-cellulosic constituents during the alkaline and bleaching treatment resulted in high pure cellulosic fibres. The isolation of CNCs from these cellulosic fibres at different reaction times was verified by the nano-dimensions of the individual crystals (< 3 and < 335 nm of average diameter and length, respectively). The highest yield (15%) and the optimum CNCs properties in terms of aspect ratio, thermal stability and crystallinity were obtained for an extraction time of 45 min. PC appeared to be a new promising source of cellulose fibres and CNCs with potential to be applied as reinforcement in composites and for food-packaging.

    Abstract [en]

    Background: Human Immunodeficiency Virus (HIV), is a virus disease which infects through blood and sexual contacts. A person with HIV can live without any physical symptoms if he or she gets the right treatments. When it first was discovered, the disease created a lot of fear and prejudices that to some extent still exists. Purpose: To describe people´s experiences of living with HIV. Method: Narrative analysis were six autobiographies written by people with HIV was analyzed. Results: From the analysis of data material two categories emerged, A changed life and valuing the experiences of having HIV with seven subcategories. Conclusion: People with HIV are experiencing a worse personal health due to feelings like loneliness and alienation. The prejudices about the disease can be reduced by increased knowledge in healthcare. A nurse can increase these persons wellbeing by having good knowledge about the disease, give a respectful treatment and inform about sexual health.

    Patienters upplevelse av ett liv med bipolär sjukdom: En självbiografistudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Bipolar disease keeps spreading across Sweden and causes great suffering. The disease alternates between recurrent manic and depressive relapses, taking its toll both physically and mentally. The disease has a high mortality and nurses need understanding and knowledge to find the right tools with which they are able to make a difference for people with bipolar disease. Aim: To describe patients experiences of the influence of bipolar disease in the daily life. Method: A qualitative content analysis with an inductive approach. The data was gathered from autobiographies written by people diagnosed with bipolar disease. Result: From the analysis of data material two themes emerged: Living between extremes and Feelings of not fitting in and being singled out. The informants experienced great contrasts in the symptoms, from complete darkness to feelings of invincibility with nine subthemes. Conclusion: Life with bipolar disease causes great suffering, both mentally and physically. Nurses have the opportunity to ease this suffering, but this will need knowledge and understanding of bipolar disease.

    Sjuksköterskors erfarenheter av att vårda personer med demens på akutvårdsavdelningar: En litteraturbaserad studie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The diagnoses of dementia increases in line with the aging population of the earth. Symptoms vary between different dementia diagnoses and for some, a diagnosis might be a relief and confirmation of what’s really going on for both the patient and their relatives. Person centered care aims to empower a person's self-esteem and involvement in their own care. It urges healthcare professionals to look beyond the diagnosis of the patient, which makes this the form of care advocated for patients with dementia. Despite the fact that long waiting times is an acknowledged problem, nurses are still obliged to pursue nursing on equal standardse. Aim: The aim was to acknowledge nurses' experiences of caring for patients with dementia in acute care settings Method: A literature-based study with nine qualitative articles were chosen. Results: The analysis identified three main categories; lack of knowledge, structural deficiencies and relatives as a co-actor of the caring process, and eight subcategories. Conclusion: Dedication and education are central aspects regarding the care of patients with dementia. It becomes apparent that regardless of context, caring for patients with dementia is often mired in complexity. Nurses claim that lack of time and education combined with structural deficiencies constitutes an obstacle for nurses providing what they would consider sufficient care. These deficiencies may also negatively affect attitudes and perceptions and consequently the care of patients with dementia can be stigmatized.

    Anorexia nervosa - unga kvinnors upplevelser av mötet med vårdpersonalen: En självbiografistudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Anorexia nervosa usually affects young women. The disease is based on askewed perception of the body, which leads to dieting to reach an ideal weight. Individualswith anorexia nervosa can have bad self-image and low self-confidence which can result intoself-destructive behavior and suffering. The nurse during the meeting needs to show trustand create safety for the patient. Professional support by communication and interaction canestablished a good care relationship. Aim: To describe how young women diagnosed withanorexia nervosa experience the meeting with health professionals. Method: The datamaterial consists of five autobiographies that have been analyzed with qualitative contentanalysis. Results: The analysis revealed four categories; feel unfairly treated, ending up indisadvantage, exposed to abuse of power and compulsion, hope and confidence. A total ofeight subcategories emerged. Conclusion: The meeting with healthcare is experienced bothnegatively and positively. It is important that healthcare professionals respect the youngwomen’s autonomy and engage them in their healthcare. That the healthcare should becharacterized by an ethical perspective and that time is given in the meeting is important.Good treatment, adequate knowledge and non-judgmental attitudes from healthprofessionals are important.

    Abstract [en]

    Background: Chronic kidney disease in later stages demands dialysis-treatment. Haemodialysis is the most common type of dialysis and is usually performed at a hospital ward. Haemodialysis brings different complications and side effects that can be perceived tough for patients. Beyond the side effects the patients also receives fluid and diet restrictions. These factors affects the patient’s everyday life. Aim: The aim is to describe patients, with chronic kidney disease, experiences of living with haemodialysis. Method: The method of choice is a literature-based study. Result: The result is presented in three main categories. Patients describes different experiences of how haemodialysis affects the body, both positive and negative. During the treatment different existential thoughts and feelings related to the own mortality appears. Patients describes that they seek support with both related and health personnel but that it can be tough to talk about existential thoughts. Conclusion: Haemodialysis treatment had a limiting effect on patient’s life, they experience an increased feeling of loneliness. A central factor for patients to be able to find support was that they feel reliance and trust in health personnel.

    A NEW STUDY OF UNBALANCED PRODUCTION LINE WITH OPTIMIZATION2018Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This project is a continuous research of a topic well-known in the literature, namely, the performance study of unbalanced unpaced production system. In the literature, there were many studies that investigated the statistical outputs of an unbalanced production line using simulation. This project focuses on researching the outputs like average buffer level and idle time that are rarely studied in previous research by using optimization tools from discrete event simulation software FACTS.The models used in the article (Shaaban & McNamara, 2009) have been used as a guideline during the development of the simulation models for this project. Two simulation models were created, each using different discrete event simulation software, namely FACTS analyzer and Plant simulation. Those simulation models fulfills its role in verification & validation stage, with their statistical outputs compared to each other and with Shaaban and McNamara’s results. After verification & validation comes optimization of those simulation models, by using optimization tools from FACTS.The research area expanded during the optimization phase. Originally Shaaban et.al analyzed unbalanced production line with one fixed value of coefficient of variation. In order to expand the view on the properties of an unbalanced production line, three more coefficient variation were added with total of four in this project. As a result, 12 optimization results were created at the end of this project. Each optimization has 30 000 iterations to ensure its convergence.The first step of analysis is done by locating all Pareto-optimal solutions with optimization tools in FACTS. The raw data of all solutions are later transferred and converted into EXCEL files. Using scatter graph and putting all outputs against each other in EXCEL, it creates visual graph that can be used to analyze and to investigate interesting behavior in an unbalanced production line.The analysis on the optimization results showed several interesting behaviors from production line with different settings. One being that if a production line possess worse coefficient of variation than its competition. By raising the inter-stage buffer level of the production line with inferior coefficient of variation, it can achieve the same level, if not greater outputs than its competitor who possess better coefficient of variation. The other interesting behavior are optimization results with highest outputs in regard of either idle time or average buffer level, with deep analyzation using optimization tools from FACTS. Certain operation time pattern and inter-stage buffer pattern could be observed from those results.

    Metamodel Based Multi-Objective Optimization with Finite-Element Applications2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    As a result of the increase in accessibility of computational resources and the increase of computer power during the last two decades, designers are able to create computer models to simulate the behavior of complex products. To address global competitiveness, companies are forced to optimize the design of their products and production processes. Optimizing the design and production very often need several runs of computationally expensive simulation models. Therefore, integrating metamodels, as an efficient and sufficiently accurate approximate of the simulation model, with optimization algorithms is necessary. Furthermore, in most of engineering problems, more than one objective function has to be optimized, leading to multi-objective optimization(MOO). However, the urge to employ metamodels in MOO, i.e., metamodel based MOO (MB-MOO), is more substantial.Radial basis functions (RBF) is one of the most popular metamodeling methods. In this thesis, a new approach to constructing RBF with the bias to beset a priori by using the normal equation is proposed. The performance of the suggested approach is compared to the classic RBF and four other well-known metamodeling methods, in terms of accuracy, efficiency and, most importantly, suitability for integration with MOO evolutionary algorithms. It has been found that the proposed approach is accurate in most of the test functions, and it was the fastest compared to other methods. Additionally, the new approach is the most suitable method for MB-MOO, when integrated with evolutionary algorithms. The proposed approach is integrated with the strength Pareto evolutionary algorithm (SPEA2) and applied to two real-world engineering problems: MB-MOO of the disk brake system of a heavy truck, and the metal cutting process in a turning operation. Thereafter, the Pareto-optimal fronts are obtained and the results are presented. The MB-MOO in both case studies has been found to be an efficient and effective method. To validate the results of the latter MB-MOO case study, a framework for automated finite element (FE) simulation based MOO (SB-MOO) of machining processes is developed and presented by applying it to the same metal cutting process in a turning operation. It has been proved that the framework is effective in achieving the MOO of machining processes based on actual FE simulations.

    A founder's heritage: the development of organizational identity2018In: Journal of Small Business and Entrepreneurship, ISSN 0827-6331, E-ISSN 2169-2610Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to understand how a former family firm strategically makes use of the founder's legacy to preserve its organizational identity. Following a single case study approach, it draws on rich empirical material from semi-structured interviews and extensive archival data. We show how central organizational activities are affected by a founder's heritage long after the formal exit has taken place, illustrating the central, enduring, and distinctive elements of organizational identity a founder has. Regardless of ownership forms, the family company founder's legacy is used to legitimize new owners and maintain the organization's identity. However, centripetal moves complicate the preservation of the organizational identity, whereas a high focus on value leveraging in another ownership form opens up for centrifugal approaches which strengthen the entrepreneurial dimension of organizational identity.

    Utgången kommer inte att förändras, men resan dit kan påverkas: Närståendes upplevelser av palliativ vård i hemmet2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Palliative home care is becoming increasingly common in Sweden. Close relatives' participation is often a prerequisite for this care to be feasible. For close relatives to be able to provide palliative care for the patient, it is important that the nurse provides support and information. Maintaining vitality and the rhythm in life is important for maintaining health. Purpose: The purpose of the study was to describe the close relatives experiences of participating in palliative care perform at home. Method: A qualitative literature review was conducted to gain a deeper understanding of the experiences described by close relatives. 12 articles were selected and the data collected was then analyzed in three steps. Outcome: The outcome described close relatives experiences of the changes in everyday life and the home environment, that care entailed a major responsibility and their own needs were set aside. There are also experiences of control verses the lack of control and the meaningfulness that can be experienced by caring. Conclusion: The importance of support and information as well as the importance of being involved and being in control of the situation was highlighted here.

    Copingstrategier hos patienter med KOL: En litteraturöversikt2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: COPD is a disease that affects the airways and the lungs. The disease is characterized by the patient having a limited airflow and the most common risk factor for COPD is tobacco smoke. COPD affects the entire lifeworld of the patient as the disease has both physical and mental impact and the patient is often in need of support. To handle stress-causing factors, people use different coping strategies, and these may vary depending on the situation, experience, and support available around the person. Aim: To describe coping strategies in patients with COPD and thereby create an understanding of these patients need for support. Method: The study is a literature review where nine articles with a qualitative approach and one article with a quantitative approach have been analyzed. Result: The result is presented with the categories Coping strategies for managing emotions and thoughts and Coping strategies that focus on change. In these categories different coping strategies of COPD patients are described in ten subcategories. Conclusion: Which coping strategies COPD-patients use depends on their lifeworld and what social and professional support is available around them. The coping strategies that focus on change are especially those who promote health, but other coping strategies are also common since the disease is associated with shame and guilt. The nurse must pay attention to the patients' coping strategies and provide them with support in implementing coping strategies that promote health.

    Sjuksköterskors erfarenheter av att bemöta existentiella frågor som kan vara svåra att besvara: En intervjustudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Patients in need of palliative care increases in home care. Existential needs are a major part of palliative care and need to be provided for the patients to feel quality of life at the end of life. Nurses have an important part in supporting and responding to patients in their existential questions.Aim: The purpose is to describe the nurses experience of responding to patients existential questions in palliative care in home care.Method: In this study a qualitative content analysis was used. Seven nurses were interviewed.Result: Two categories emerged, these were: Provide the patients rights and Adaptable attitude towards the patients. Nurses experience that patients existential questions are a difficult but a significant part of end of life care. Other experiences that nurses have is that conversations should be prioritized and to see the patients needs to respond to patients existential questions.Conclusion: This study has revealed that nurses do not need to be afraid of responding to existential questions. Collaboration with other professions can benefit both patients and nurses.

    Närståendes upplevelser efter att en anhörig har begått suicid: En litteraturstudie baserad på självbiografier2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Suicide is self-destructive act that leads to death and is usually a consequence of mental illness and disease. Suicide also leads to great suffering for the relatives left behind. The nurse’s role in cases like these is therefore to acknowledge and support relatives in their grieving process. Aim: Is to describe relatives’ lived experiences after their next of kin commits suicide in order to create an understanding on how nurses can respond to their needs. Method: The study was based on seven autobiographies. Dahborg-lyckhage’s method for analyzing narratives was used to analyze the chosen biographies. Results: The results describe the relatives’ feelings like guilt, shame, relief among others and reactions after their next of kin’s suicide. They experienced avoidance by people in their surroundings. They also lacked professional support to assist them in their bereavement and had to reach out for it themselves. Conclusion: Nurses have a role to fulfill with supporting relatives in their grieving process with aim to help on improving their wellbeing and relieve their suffering. Information about support groups and helpful organizations like SPES as a form of social support can be very helpful in achieving this.

    Mina kramar smittar inte: En analys av bloggar om hur det är att leva med HIV2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: HIV is a virus that in the long run damages the immune system. Without medicinal treatment it causes serious secondary diseases. There is a stigmatization in society about HIV and therefore it is psychologically strenuous to be a HIV carrier. Nursing care is therefore important. Nurses need to strive towards giving HIV carriers a good reception to avoid care suffering. Aim: To describe what it is like to live with HIV and thereby increase nurses’ understanding of HIV carriers’ life situation. Method: This study is an analysis of blogs based on a qualitative content analysis. Ten blogs represents the source for data. Results: The results describe HIV carriers’ feelings around and after they found out that they are HIV-positive, and the path to acceptance and manageability. The results also describe how the stigmatization around HIV is shown in society and healthcare and also how it affects HIV carriers’ health and life situation. HIV carriers consider that society’s gaps in knowledge need to be filled to decrease stigmatization. Conclusion: Nurses have a key role in supporting HIV carriers in their health process and they are responsible for ensuring that the care that HIV carriers receive is person-centered. Increased knowledge about HIV is needed both in healthcare and society. By increasing the knowledge a better understanding for these individuals’ life situation is reached.

    Sjuksköterskestudenters möte med den döende patienten: En enkätstudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Nursing students need the support to be prepared to nurture patients in apalliative stage. End-of-life care is a demanding area. The student's encounter with death anddying has been described as causing feelings of fear and anxiety. Care at the end of life hasbeen shown to have been a small part of nursing education. The author of this study,therefore, wishes to highlight the importance of nursing education putting more emphasis onteaching about palliative care. Purpose: The purpose is to describe nursing students'perception of meeting patients in a palliative stage. Methodology: The study uses aqualitative content analysis with questionnaire survey in which 75 students from the thirdterm can answer four statements in free text. Result: The results is presented with twocategories; Nursing students knowledge and experience lead to a profession and beingethically correct by showing empathy for care at the end of life. Based on the categories,subcategories were created that describe in more detail the students' perception of meetingpatients in a palliative stage. Conclusion: The experiences can be both positive and negative.Being able to care for severely ill and dying patients is something that is expected of nursesregardless of the workplace. It has been demonstrated in a number of studies that nursingstudents need support in order to care for the patients in a palliative phase as it can bringstrong feelings to the student.

    Gäst i Katas hus: En undersökning av fiktionens roll i museet2018Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This work is about fiction in the museum, and an approach towards transmedia storytelling with two different methods of mediation. With background in literature on cultural heritage, mediation in museums, mediation of history, fiction, transmedia storytelling and adaptation, visitors’ discussions about an exhibition and a fictional text was examined. In order to make the two methods of mediation converge, a number of themes from the existing exhibition were adapted and encapsulated in a fictional story.The visitors were primarily interested in a historical discussion in regards to the two methods of mediation. The message in both methods was considered to be historical, although different reasons as to why were expressed. The discussion about the fictional text emanated from a traditional view of historical fiction, i.e. was considered by the visitors to be provocative or compelling fictional prose that may guide a visitor to the exhibit. Somewhat contradictory to this expressed meaning, the visitors’ discussion about the fiction revealed a more suggestive and imaginative relationship with the subject matter, suggesting that fiction in the museum is a means to problematize meaning making in the museum, if they should promote experiences or build frameworks for learning in an authoritative method of mediation.

    Framställning av mätmetod för att upptäcka defekta luftmunstycken: Framställa en säker och tillförlitlig mätmetod för att mäta mängd vatten i 50 provrör2018Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    To detect defective air nozzles, Ecco Finishing AB in Skara has developed a new test equip-ment to replace an unreliable and uncertain existing test machine. Ecco Finishing AB wants to find a reliable and safe measurement method that will measure the amount of water in 50 test tubes. The overall goal of the thesis is to find a precise and repeatable measurement method for level measurement of fluid in the test tubes. Two measurement methods were evaluated that are most suitable for level measurement, vision systems and measurement by weighing. The reason for the choice of these two measurement methods is the test tubes of the test equipment, and that there are many measuring points and because of the small test tubes. Twenty experiments for vision systems and twenty experiments for weighing method were made to evaluate and describe pros and cons. The experiments of vision systems and weighing were first made in the laboratory phase and then tested on the company's existing test equipment. The results of measurements were saved in an Excel sheet used to evaluate collected data. The evaluations were compared to set goals, reliability, accuracy, repeatabil-ity, automatic reporting of results and time of measurement. Vision systems are recom-mended for continued work and implementation on the existing test equipment.

    Toward Predictive Maintenance in a Cloud Manufacturing Environment: A population-wide approach2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The research presented in this thesis is focused on improving industrial maintenance by using better decision support that is based on a wider range of input information. The core objective is to research how to integrate information from a population of similar monitored objects. The data to be aggregated comes from multiple disparate sources including double ball-bar circularity tests, the maintenance management system, and the machine tool’s controller. Various data processing and machine learning methods are applied and evaluated. Finally, an economic evaluation of the proposed approach is presented. The work performed is presented in five appended papers.

    Paper I presents an investigation of cloud-based predictive maintenance concepts and their potential benefits and challenges.

    Paper II presents the results of an investigation of available and potentially useful data from the perspective of predictive analytics with a focus on the linear axes of machine tools.

    Paper III proposes a semantic framework for predictive maintenance, and investigates means of acquiring relevant information from different sources (i.e., ontology-based data retrieval).

    Paper IV presents a method for data integration. The method is applied to data obtained from a real manufacturing setup. Simulation-based evaluation is used to compare results with a traditional time-based approach.

    Paper V presents the results from additional simulation-based experiments based on the method from Paper IV. The aim is to improve the method and provide additional information that can support maintenance decision-making (e.g., determining the optimal interval for inspections).

    The method developed in this thesis is applied to a population of linear axes from a set of similar multipurpose machine tools. The linear axes of machine tools are very important, as their performance directly affects machining quality. Measurements from circularity tests performed using a double ball-bar measuring device are combined with event and context information to build statistical failure and classification models. Based on those models, a decision-making process is proposed and evaluated. In the analysed case, the proposed approach leads to direct maintenance cost reduction of around 40 % compared to a time-based approach.

    TWITTERING MACHINE #3: REDUX - THE DOOMSDAY MACHINE2018Artistic output (Refereed)
    Abstract [en]

    Twittering Machine #3 is the third composition Lars Bröndum has composed which is inspired by Paul Klee’s painting Die Zwitscher-Maschine (Twittering Machine). The composition was completed in 2017 and was rearranged in 2018 for a slightly smaller orchestra (thus the added title “redux”). The piece was chosen in a call for works by a committee of representatives from Jönköping Sinfonia in conjunction with Kungliga Musikaliska Akademien (Swedish Royal Accademy) och Svensk Musik for a performance by the Jönköping Sinfonietta 27 April, 2018.

    Bröndum has written three compositions based on the Klee painting Die Zwitscher-Maschine. The three “Machines” are varied in some aspects, such as, harmony, melodies and instrumentation but are very similar in form.  It is as if the machine is cranked up and sounding slightly different several years apart. Conceptually the sound may vary slightly because the mechanics has deteriorated or maybe have been repaired or because of mechanical errors. In the third twittering machine Bröndum was imagining a giant doomsday bird machine being cranked up creating a cacophony of sound.  The first two twittering machines are free in tempo at sections, but the third twittering machine is strict in tempo like a military machine.

    Twittering Machine #3 is subtitled “Doomsday Machine” and is dedicated to Alfred Hitchcock as a reference to his classic movie Birds (1963).  The composition is similar to the movie - a menacing and foreboding piece. There is also a subtle reference to Donald Trump’s uncontrolled Tweets that very likely could cause the doomsday. It is scored for Flute, Oboe, English Horn, Clarinet in Bb, Bass Clarinet, Contrabassoon, Horn in F 1, Horn in F 2, Trumpet in C 1, Trumpet in C 2, Trombone 1, Tuba, Piano, violin I, Violin II, Viola, Cello, Contrabass.

    Musical influences and inspiration for this work can be found in Oliver Messiaen’s bird calls found in pieces like Chronochromie (1960) for orchestra and György Ligeti’s cluster techniques in works such as Athmospheres (1961) and Chamber Concerto Music for 13 Instruments (1969/70). I also use indeterminate ideas pioneered by John Cage and Pierre Boulez.

    Sjuksköterskors erfarenheter av att möta patienter med autismspektrumtillstånd: En litteraturöversikt2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Autism spectrum disorder (ASD) is a collective name for many neuropsychiatric disabilities. Understanding, routines and a lack of overall perception characterize the diagnosis. Communication and knowledge about ASD is something that fails in meeting with these patients. Therefore, knowledge of ASD and how these patients experience the meeting with care are significant in promoting nursing and their health. Aim: To describe the nurses experience of meeting patients diagnosed with ASD. Methods: A literature review with qualitative and quantitative approach based on ten scientific articles. Results: The analysis revealed two themes; adaptation and preparation in the meeting as well as the importance of knowledge and competence in the meeting, with four sub-men. Conclusion: The nurse should be engaged in the patient and it´s situation in the meeting and have a good dialogue with close associates and work in teams to find the right approaches in the meeting. It´s important that the nurse has knowledge and education about ASD and the various communication aids that are considered to be one of the promotional factors.

    Distriktssköterskors erfarenheter av att främja egenvårdsförmågan hos äldre patienter med diabetes typ 2: En kvalitativ intervjustudie2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Diabetes type 2 is a disease which is growing in the society and among elders. Many of these need care in the form of home healthcare. Home healthcare is a care form which is increasing as the hospitals have lesser hospital beds. This increases the demands of home healthcare and its resources. Self-care is a central part within the diabetes-care and when well-functioning it can reduce the risk of diabetes-related complications. Elderly though, have a more difficult time to maintain good self-care abilities due to the natural ageing and other possible diseases.Aim: The aim of this study was to illustrate district-nurses experiences of promoting self-care abilities among elderly patients with diabetes type 2 in home health-care settings. Method: Data were analyzed with an inductive approach by a qualitative content analysis. The data collection was made through interviews with ten district-nurses active in home health-careResults: From the analysis appeared a theme; the importance of enabling small diabetes-related lifestyle changes, and three categories; The elderlies limitations to self-care, Individualized self-care-guidance and Cooperation between different professions with seven subcategories.Conclusion: The study shows that the district-nurses have a supportive role in promoting patients self-care abilities. They cooperate with other professions to provide tools and measures needed for promoting their independency and opportunities for self-care.

    Sjuksköterskors erfarenheter av att använda tolk i möten med patienter2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: In encounters between nurses and patients with another language could communication problem arise. In those situations, an authorized interpreter could be needed. The need of authorized interpreters arises when the immigration increased and the society became multilingual. There could be some communication challenges during the meetings when the nurse has difficulties to understand and to pass information to a patient from a different cultural with another language background. The responsibility of the nurse and the large part of the work is to make the patient involved and agreed upon the care service that is needed. Aim: The purpose was to describe nurses’ experiences of using an interpreter in encounters with patients. Method: A literature-based study with ten qualitative articles were chosen. Result: The analysis resulted in three categories; Different opinions regarding the importance of the interpreter, unclear guidelines and that relatives should not need to act as an interpreter and eight subcategories. Conclusion: There was an obvious conclusion how important it is for nurses to make the patient involved and agreed upon in the meetings regardless from earlier background and language. The patient involvement is of great importance to nurses to secure and meet a good care. If the patient’s wishes of not using an interpreter, it could lead to a suffering for the patient.
