Ingår i: User Interfaces. ; , s. 23-

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- User profile is a popular term widely employed during product design processes by industrial companies. Such a profile is normally intended to represent real users of a product. The ultimate purpose of a user profile is actually to help designers to recognize or learn about the real user by presenting them with a description of a real user’s attributes, for instance; the user’s gender, age, educational level, attitude, technical needs and skill level. The aim of this chapter is to provide information on the current knowledge and research about user profile issues, as well as to emphasize the importance of considering these issues in interface design. In this chapter, we mainly focus on how users’ difference in expertise affects their performance or activity in various interaction contexts. Considering the complex interaction situations in practice, novice and expert users’ interactions with medical user interfaces of different technical complexity will be analyzed as examples: one focuses on novice and expert users’ difference when interacting with simple medical interfaces, and the other focuses on differences when interacting with complex medical interfaces. Four issues will be analyzed and discussed: (1) how novice and expert users differ in terms of performance during the interaction; (2) how novice and expert users differ in the perspective of cognitive mental models during the interaction; (3) how novice and expert users should be defined in practice; and (4) what are the main differences between novice and expert users’ implications for interface design. Besides describing the effect of users’ expertise difference during the interface design process, we will also pinpoint some potential problems for the research on interface design, as well as some future challenges that academic researchers and industrial engineers should face in practice.

Scientific Models
- 2016
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- A zebrafish, the hull of a miniature ship, a mathematical equation and a food chain - what do these things have in common? They are examples of models used by scientists to isolate and study particular aspects of the world around us. This book begins by introducing the concept of a scientific model from an intuitive perspective, drawing parallels to mental models and artistic representations. It then recounts the history of modelling from the 16th century up until the present day. The iterative process of model building is described and discussed in the context of complex models with high predictive accuracy versus simpler models that provide more of a conceptual understanding. To illustrate the diversity of opinions within the scientific community, we also present the results of an interview study, in which ten scientists from different disciplines describe their views on modelling and how models feature in their work. Lastly, it includes a number of worked examples that span different modelling approaches and techniques. It provides a comprehensive introduction to scientific models and shows how models are constructed and used in modern science. It also addresses the approach to, and the culture surrounding modelling in different scientific disciplines. It serves as an inspiration for model building and also facilitates interdisciplinary collaborations by showing how models are used in different scientific fields. The book is aimed primarily at students in the sciences and engineering, as well as students at teacher training colleges but will also appeal to interested readers wanting to get an overview of scientific modelling in general and different modelling approaches in particular.

- 2022
-
Ingår i: Frontiers in Human Neuroscience. - : Frontiers Media SA. - 1662-5161. ; 16

Forskningsöversikt (refereegranskat)abstract
- Background: Upper limb impairment is common after stroke, and many will not regain full upper limb function. Different technologies based on surface electromyography (sEMG) have been used in stroke rehabilitation, but there is no collated evidence on the different sEMG-driven interventions and their effect on upper limb function in people with stroke. Aim: Synthesize existing evidence and perform a meta-analysis on the effect of different types of sEMG-driven interventions on upper limb function in people with stroke. Methods: PubMed, SCOPUS, and PEDro databases were systematically searched for eligible randomized clinical trials that utilize sEMG-driven interventions to improve upper limb function assessed by Fugl-Meyer Assessment (FMA-UE) in stroke. The PEDro scale was used to evaluate the methodological quality and the risk of bias of the included studies. In addition, a meta-analysis utilizing a random effect model was performed for studies comparing sEMG interventions to non-sEMG interventions and for studies comparing different sEMG interventions protocols. Results: Twenty-four studies comprising 808 participants were included in this review. The methodological quality was good to fair. The meta-analysis showed no differences in the total effect, assessed by total FMA-UE score, comparing sEMG interventions to non-sEMG interventions (14 studies, 509 participants, SMD 0.14, P 0.37, 95% CI –0.18 to 0.46, I2 55%). Similarly, no difference in the overall effect was found for the meta-analysis comparing different types of sEMG interventions (7 studies, 213 participants, SMD 0.42, P 0.23, 95% CI –0.34 to 1.18, I2 73%). Twenty out of the twenty-four studies, including participants with varying impairment levels at all stages of stroke recovery, reported statistically significant improvements in upper limb function at post-sEMG intervention compared to baseline. Conclusion: This review and meta-analysis could not discern the effect of sEMG in comparison to a non-sEMG intervention or the most effective type of sEMG intervention for improving upper limb function in stroke populations. Current evidence suggests that sEMG is a promising tool to further improve functional recovery, but randomized clinical trials with larger sample sizes are needed to verify whether the effect on upper extremity function of a specific sEMG intervention is superior compared to other non-sEMG or other type of sEMG interventions.

Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 10:2
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The Swedish Dementia Registry (SveDem) was developed with the aim to improve the quality of diagnostic work-up, treatment and care of patients with dementia disorders in Sweden. Methods: SveDem is an internet based quality registry where several indicators can be followed over time. It includes information about the diagnostic work-up, medical treatment and community support (www.svedem.se). The patients are diagnosed and followed-up yearly in specialist units, primary care centres or in nursing homes. Results: The database was initiated in May 2007 and covers almost all of Sweden. There were 28 722 patients registered with a mean age of 79.3 years during 2007-2012. Each participating unit obtains continuous online statistics from its own registrations and they can be compared with regional and national data. A report from SveDem is published yearly to inform medical and care professionals as well as political and administrative decision-makers about the current quality of diagnostics, treatment and care of patients with dementia disorders in Sweden. Conclusion: SveDem provides knowledge about current dementia care in Sweden and serves as a framework for ensuring the quality of diagnostics, treatment and care across the country. It also reflects changes in quality dementia care over time. Data from SveDem can be used to further develop the national guidelines for dementia and to generate new research hypotheses.

Enlarged Training Dataset by Pairwise GANs for Molecular-Based Brain Tumor Classification
- 2020

Tidskriftsartikel (refereegranskat)abstract
- This paper addresses issues of brain tumor subtype classification using Magnetic Resonance Images (MRIs) from different scanner modalities like T1 weighted, T1 weighted with contrast-enhanced, T2 weighted and FLAIR images. Currently most available glioma datasets are relatively moderate in size, and often accompanied with incomplete MRIs in different modalities. To tackle the commonly encountered problems of insufficiently large brain tumor datasets and incomplete modality of image for deep learning, we propose to add augmented brain MR images to enlarge the training dataset by employing a pairwise Generative Adversarial Network (GAN) model. The pairwise GAN is able to generate synthetic MRIs across different modalities. To achieve the patient-level diagnostic result, we propose a post-processing strategy to combine the slice-level glioma subtype classification results by majority voting. A two-stage course-to-fine training strategy is proposed to learn the glioma feature using GAN-augmented MRIs followed by real MRIs. To evaluate the effectiveness of the proposed scheme, experiments have been conducted on a brain tumor dataset for classifying glioma molecular subtypes: isocitrate dehydrogenase 1 (IDH1) mutation and IDH1 wild-type. Our results on the dataset have shown good performance (with test accuracy 88.82%). Comparisons with several state-of-the-art methods are also included.

Tidskriftsartikel (refereegranskat)abstract
- PROBLEM: The current knowledge of evidence-based design for adults is not always implemented when hospital buildings are designed. Scientific data are sparse on the effects of hospital design in pediatric settings on health outcomes in children, parents, and staff. The objective of this review is to determine the evidence-based impact of the built environment in pediatric hospital facilities on health outcomes in children, parents, and staff.ELIGIBILITY CRITERIA: A systematic literature review was carried out on the electronic databases Cochrane Library, Embase, Medline and CINAHL from the period of 2008 to 2019. The review considered studies using either quantitative, qualitative, or mixed methodologies.SAMPLE: Out of 1414 reviewed articles the result is based on eight included articles.RESULTS: Two of these eight articles included health outcomes. The other six articles presented results on measures of perceptions and/or satisfaction for children, parents or staff with the built environment when transitioning to a new or renovated facility. These were generally higher for the new compared to the old facility.CONCLUSIONS: Given the small number of studies addressing the question posed in this review, no firm conclusions can be drawn.IMPLICATIONS: The review illustrates the need for more research in the pediatric setting assessing the evidence-based health outcomes of aspects of physical environmental design in pediatric hospitals or units in children, parents and staff.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To explore women’s experiences of physical features in a birthing room designed to be adaptable to personal wishes and needs during labor and birth. Background: Childbirth is a central life event influenced by numerous factors, including the healthcare environment; however, there is insufficient knowledge on how the physical design affects women during birth. Methods: This study was part of a randomized controlled trial in the Room4Birth research project, including women randomized to receive care in a new birthing room designed with physical features changeable according to personal wishes. Data consisted of responses to two questions analyzed with descriptive statistics (n = 202) and semi-structured interviews analyzed for content (n = 19). Results: A total of 93.6% (n = 189) assessed the physical features in the birthing room as meaningful to a very high or high extent. The overall impression of the room was positive and exceeded women’s expectations. They felt welcomed and strengthened by the room, which shifted the focus to a more positive emotional state. The room differed from traditional hospital birthing rooms, contained familiar features that maintained integrity, and had space for companions. The variety of physical features was appreciated. Of nine listed physical features, the bathtub was ranked most important, followed by the projection of nature scenery, and dimmable lighting, but the room as a whole appeared most important. Conclusions: When planning and designing hospital-based birthing rooms, it is crucial to offer possibilities to adapt the room and physical features according to personal wishes.

Tidskriftsartikel (refereegranskat)abstract
- Older adults have multiple medical and social care needs, requiring a shift toward an integrated person-centered model of care. Our objective was to describe and summarize Swedish experiences of integrated person-centered care by reviewing studies published between 2000 and 2023, and to identify the main challenges and scientific gaps through expert discussions. Seventy-three publications were identified by searching MEDLINE and contacting experts. Interventions were categorized using two World Health Organization frameworks: (1) Integrated Care for Older People (ICOPE), and (2) Integrated People-Centered Health Services (IPCHS). The included 73 publications were derived from 31 unique and heterogeneous interventions pertaining mainly to the micro- and meso-levels. Among publications measuring mortality, 15% were effective. Subjective health outcomes showed improvement in 24% of publications, morbidity outcomes in 42%, disability outcomes in 48%, and service utilization outcomes in 58%. Workshop discussions in Stockholm (Sweden), March 2023, were recorded, transcribed, and summarized. Experts emphasized: (1) lack of rigorous evaluation methods, (2) need for participatory designs, (3) scarcity of macro-level interventions, and (4) importance of transitioning from person- to people-centered integrated care. These challenges could explain the unexpected weak beneficial effects of the interventions on health outcomes, whereas service utilization outcomes were more positively impacted. Finally, we derived a list of recommendations, including the need to engage care organizations in interventions from their inception and to leverage researchers’ scientific expertise. Although this review provides a comprehensive snapshot of interventions in the context of Sweden, the findings offer transferable perspectives on the real-world challenges encountered in this field.
