Identifying the Barriers to Acceptance of Blockchain-Based Patient-Centric Data Management Systems in Healthcare

A number of recent studies have shown that wastage and inefficiency are a significant problem in all global healthcare systems. One initiative that could radically improve the operational efficiency of health systems is to make a paradigm shift in data ownership—that is, to transition such systems to a patient-centric model of data management by deploying blockchain technology. Such a development would not only make an economic impact, by radically cutting wastage, but would deliver significant social benefits by improving patient outcomes and satisfaction. However, a blockchain-based solution presents considerable challenges. This research seeks to understand the principal factors, which act as barriers to the acceptance of a blockchain-based patient-centric data management infrastructure, in the healthcare systems of the GCC (Gulf Cooperation Council) countries. The study represents an addition to the current literature by examining the perspectives and views of healthcare professionals and users. This approach is rare within this subject area, and is identified in existing systematic reviews as a research gap: a qualitative investigation of motivations and attitudes among these groups is a critical need. The results of the study identified 12 key barriers to the acceptance of blockchain infrastructures, thereby adding to our understanding of the challenges that need to be overcome in order to benefit from this relatively recent technology. The research is expected to be of use to healthcare authorities in planning a way forward for system improvement, particularly in terms of successfully introducing patient-centric systems.

The lived experience of withdrawal from Selective Serotonin Reuptake Inhibitor (SSRI) antidepressants: A qualitative interview study.

Our knowledge of the broader impacts of antidepressant withdrawal, beyond physical side effects, is limited. Further research is needed to investigate the lived experiences of withdrawal, to aid clinicians on how to guide patients through the process. To explore antidepressant users' experiences and views on the withdrawal process and how it affected their quality of life across multiple life domains. We conducted in-depth qualitative interviews with 20 individuals from the community who had attempted to withdraw from Serotonin Reuptake Inhibitor antidepressants in the past year. Semi-structured interviews were conducted online. A topic guide was used to ensure consistency across interviews. The interviews were audio-recorded and transcribed verbatim and analysed using inductive reflexive thematic analysis. Five themes were generated. The first highlighted the challenges of managing the release from emotional blunting and cognitive suppression following antidepressant discontinuation. The second related to the negative impact of withdrawal on close relationships and social interactions. The third showed that concurrent with negative physical symptoms, there was a positive impact on health (exercise was reported by some as a coping mechanism). The fourth theme focused on support from GPs and families, emphasising the importance of mental health literacy in others. The final theme underscored the importance of gradual and flexible tapering in enabling a manageable withdrawal experience,and the consideration of timing. The lived experience of withdrawal significantly impacts individuals' well-being. Participants emphasised that withdrawal is not just about physical side effects but also affects their emotional, cognitive, and social functioning. Eight people attended individual online meetings to share their experiences of antidepressant withdrawal to help inform the study design and recruitment strategy. Insights from these meetings informed the development of the topic guide. Questions about GP involvement, family relationships, and mood and thinking changes were included based on this PPI work. This ensured the inclusion of topics important to antidepressant users and facilitated the researcher's questioning during the interviews.

AVALIAÇÃO DOS ATRIBUTOS ESSENCIAIS NA ESTRATÉGIA SAÚDE DA FAMÍLIA: PERSPECTIVA DOS USUÁRIOS E USUÁRIAS

ABSTRACT Objective: to evaluate the presence and extent of the essential attributes of Primary Health Care from the perspective of users of the Family Health Strategy. Method: this was a cross-sectional, quantitative study of 256 users of 26 family health units in Santa Catarina, Brazil, carried out between June and December 2021. A characterization questionnaire and the Primary Care Assessment Instrument were used. Descriptive and inferential statistics analysis was carried out. Results: users evaluated the units as having a sub-optimal score for the presence and extent of the essential attributes. However, users with health problems rated the essential score (p=0.001), the longitudinality attribute (p=0.024), and the comprehensiveness attribute (p=0.001) positively.). Conclusion: periodically evaluating the presence and extent of the attributes makes it possible to guide strengthening strategies and contributes to the continuous improvement of Primary Care, based on indicators for qualified health management, with the difference of considering the views of users.

Analyzing and Detection of Human Emotion through Online Social Networks

Online social networks play an important role for sharing the emotion between users. It has become increasingly prevalent in various applications, including personalized ad services and recommendation systems. However, the traditional approach to emotion analysis has focused exclusively on sentence-level polarity, ignoring the information that multiple emotions can coexist in users' minds. In this study, it provides deals with the problem of multiple emotions from the user's view, which formulates a multi-label learning problem. Through analysis of an annotated Twitter dataset, we identify correlations between emotion labels, social correlations, and temporal correlations. Based on the findings from the state of art techniques a factor graph-based emotion recognition model that incorporates social, temporal, and social correlations with emotion labels. Our model utilizes a multi-label learning strategy and can detect multiple emotions more accurately than existing baselines. Overall, our study provides a novel approach to emotion detection in OSNs, with potential applications in personalized services and recommendation systems

Train passengers' perceptions and preferences for different platform and carriage design features

Specific design features and functions on the platform and inside of the train carriage can significantly affect how efficiently and smoothly passengers can move in and out of the train. Industry follows the design standard and guidelines to satisfy the minimum requirement. However, the views of rail users are often overlooked and not well understood. This study fills the knowledge gap by investigating different platform and train carriage design features and understanding train passengers' perceptions and preferences for the proposed design. An online passenger survey targeting Melbourne Metro train users was conducted. By analyzing 429 valid responses, we gained insights into passengers' perceptions and preferences regarding train and platform design. A novel finding is that a vertical pole is the most preferred handhold type, while a rigid handrail is the least preferred handhold type. The 2+2 seating is voted as the most preferred interior layout, which is consistent with previous studies. The ranking on 2+2 seating layout is moderately associated with travel time and travel frequency, while the ranking on 2+3 seating is strongly associated with travel time. It is also found that the preferences for boarding sign and occupancy sign design are significantly associated with gender, age group, and travel frequency. Surprisingly, no statistically significant associations were found between any of the personal or travel variables with queuing sign preference, side seating ranking, or hanging strips ranking. The findings drawn from the analysis and the recommendation of this paper can provide valuable guidance for rail manufacturers in implementing design changes, as well as for service operators in adopting new strategies and interventions to enhance service quality and customer satisfaction.

Ценностно-смысловые детерминанты профессиональной ответственности в обыденном представлении россиян

Background. The study of the value-meaning aspect of notions of professional responsibility is due to their potential impact on the efficiency of work and on psychological well-being of a specialist. The analysis of literary sources showed insufficient development of the emotional component of the studied phenomenon. Objectives. The article focuses on carrying out a structural and informative analysis of the views of Internet users on professional responsibility as well as on selecting value-meaning factors from the general context of representations. Study Participants. Users of the social network VKontakte and specialized Internet forums participated in the study. The number of author’s texts analysed was 1010. Each participant submitted one communication, i.e. the number of participants corresponds to the number of texts and amounts to 1,010 people. The total number of messages included 800 texts from the social network and 210 texts from the Internet forums. Methods. The study of ordinary representations of Internet users about professional responsibility is conducted with the help of statistical analysis of word occurrence frequency (PyMorphy2). Classification of the analyzed units (nouns, verbs, adjectives) is made on the basis of statistical processing and expert evaluation, structural elements of the phenomenon of “professional responsibility” and its value-meaning characteristics are shown. The analysis of contingency on the basis of testing with corpus of Russian language dataset RuTweetCorp, based on Bernoulli distribution, neuronetwork model of analysis of emotional background of messages (FastText), neuronetwork model Dostoevsky and dataset RuSentiment. Results. The conducted analysis allowed to present the structure of “professional responsibility”, to reveal cognitive, emotional, and behavioral components. The study identified a fourth meta-structural component, never previously identified by other authors, which is related to the “God” construct. The value-meaning patterns of professional responsibility have been identified and described. The analysis of the emotional background of the messages made it possible to highlight the trend towards negative assessments of the phenomenon of “professional responsibility” at the current stage of society development. Conclusions. The approach proposed in the study allows to reveal the psychological essence of professional responsibility, to highlight the importance of the emotional component in the strategies of acceptance/avoidance of responsibility. The equation of professional responsibility with personal responsibility of a specialist has been revealed, while the notions of national, social, and corporate responsibility are manifested insignificantly. The study of professional responsibility through the value-meaning aspect can become the basis for analysis of social behavior in a person as a whole in the future.

User experiences of an AI application for predicting risk of sexually transmitted infections.

Awareness of one's individual risk of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) is a necessary precursor to engagement with prevention strategies and sexual health care. Web-based sexual health applications may improve engagement in sexual health prevention and care by providing individualised and evidence-based sexual health information. The STARTOnline (Supporting Timely and Appropriate Review and Treatment Online) study sought the views of sexual health service users on three web-based sexual health applications to better understand their usefulness, acceptability and accessibility. This paper reports the views and experiences of users of one of the applications called MySTIRisk. MySTIRisk estimates the risk of three common STIs and HIV using data from attendees of a metropolitan sexual health service. This study used a bespoke qualitative design, informed by a developmental evaluation approach. Melbourne Sexual Health Centre clinic attendees' views were sought using semi-structured interviews conducted between October 2023 and January 2024 via videoconferencing, telephone and on site at the clinic. Data was analysed using qualitative data analysis methods. A diverse group of 14 participants described an ideal pathway to better sexual health outcomes that might be facilitated by use of the MySTIRisk application, particularly for individuals with limited sexual health knowledge, or affected by stigma and geographical barriers. This pathway was described as: 1) being concerned about my sexual health; 2) checking my STI risk easily and privately; 3) understanding and trusting the result; and 4) deciding how to look after my health. Factors that might influence this pathway were also described, including areas for improvement in accessibility and acceptability. These findings support the role of web-based sexual health applications in facilitating access to sexual health education and behavioural change and underscore the importance of codesign approaches in improving their uptake and impact.

Quantitative ethnobotany of plants used for vernacular building construction in Ghana.

Vernacular construction uses locally available materials, including plant-based materials. The sustainability of plant use raises concerns. Social evaluation using an ethnobotanical approach gives a clear overview of the sustainability of wild plant harvesting as it incorporates the views of resource users. In Ghana, plant-based materials are commonly used for vernacular housing construction, especially in rural areas. However, the cultural significance of plant species used for vernacular building construction remains unexplored. This study aimed to take an inventory of plant species and use their ethnobotanical indices to evaluate the sustainability of utilization in vernacular building construction. Ethnobotanical data on plant species used for vernacular building construction was collected from 258 respondents in the Adaklu district of the Volta region. Quantitative ethnobotanical analysis revealed that of the 26 plant species identified to be used for vernacular building construction, Bambusa vulgaris, Borassus aethiopum, Elaeis guineensis, Senna siamea, and Azadirachta indica were the most culturally significant and valuable. Bambusa vulgaris had the highest cultural importance, value, and relative importance index. Elaeis guineensis had the highest relative frequency of citations. The findings reveal a high potential for valorizing the culturally important and valuable plant species in the local construction industry. Promoting culturally significant and valuable plant species commercialization presents an opportunity for poverty alleviation at the local level, as most of the species are abundant in the natural environment and are among the commonly planted species for the afforestation program in Ghana.

Fintech innovation for financial inclusion: can India make it?

Purpose The purpose of this study is to examine the key research question, which is whether fintech innovation for financial inclusion has been successful in India? As fintech has been popular in many countries, there is very little understanding on how successful it has performed in India for financial inclusion. This research attempts to ravel important factors that may or may not have a direct or indirect impact on fintech innovation for financial inclusion, thereby dissecting the empirical data to reveal important information for the reader. Design/methodology/approach This study covers a comprehensive literature review, from which key variables are discovered, then develops hypotheses to be examined, followed by proposing a research model. The survey data examines important research instruments for fintech inclusion in India, identifying and measuring factors, leading to partial least squares (PLS) model testing. Finally, the key findings are reported. Findings The findings reveal that fintech innovation from variables such as users experience and motivation for digital payments drives usefulness and ease of use leading to financial inclusion. The security, trust, transparency and customer support when built into the fintech innovation for digital payments influences perceived ease of use (PEOU) and usefulness that mediates to uplift financial inclusion directly. Whereas perceived usefulness (PU) anchoring happens to be a precursor for the financial inclusion. On the contrary, cultural values for fintech innovation through PEOU and usefulness had no impact whatsoever on financial inclusion, thus demystifying cultural influences as non-influential factor. Research limitations/implications Research limitations are that the study was conducted in India, and may not be generalised in other countries; however, it can be modified to fit future research. Survey data captured was from a particular region of South India, which may differ from the rest of the country. The sample size and research period were adequate; however, larger data sets would be more meaningful for longitudinal studies. As India is the second most populous country in the world, a comparison with other similar countries of the same size and geographical location will be useful for future research. Practical implications This research reveals that financial inclusion is much more complex than previously known and that the penetration of fintech has the capacity to go deeper and include a large number of people into the mainstream financial system and ameliorate the inequities in urban-rural gender and caste. The user’s experience, culture and motivations positively influenced the usefulness and ease of use for driving the financial inclusion of digital payments. Further security, trust, transparency and customer support can facilitate the use of central bank digital currency (CBDC) as a tool for financial inclusion. Social implications Fintech innovation for financial inclusion is based on the successful acceptance of the digital payment system by people in the society. This research has identified that for any fintech innovation, it is essential that society needs to benefit from it. Encouraging a larger population to switch to digital payments offer challenges and opportunities. While the opportunities are enormous research suggests that early adopters of new technology go through different phases of testing, in which a society can completely accept an innovation or can completely reject an innovation if the two mediating factors such as PU and ease of use do not perform as predicted, thus having a higher failure rate. On the other side, if such an innovation as fintech becomes successful it has the capacity to bring billions of people into mainstream financial inclusion, a success story that can greatly benefit the Indian society and which can be replicated among other countries in the world. Originality/value To the best of the authors’ knowledge, this study is the first attempt in an effort to understand the influential factors from the point of view of users for the adoption of CBDC for financial inclusion. The main contribution of this paper is to examine the role of CBDC as an instrument to foster financial inclusion in India, which has not been attempted so far. The originality also lies to the heart of the research is dissecting and making meaningful sense of the empirical data, developing and measuring research instruments and hypotheses and finally adopting a PLS model to answer the key research question, which is whether fintech innovation for financial inclusion can be successful for India?

The Thursday Appetizer series: a community of practice for healthy and active aging in Barcelona. Identification of challenges to design innovative solutions that respond to the real needs of older persons.

In response to major challenges facing the aging population, we have launched the Barcelona Aging coLLaboratory (BALL), an open-innovation ecosystem focused on promoting healthy and active aging through the co-creation, development, testing and evaluation of innovative products and services in real-life settings. In line with the quadruple helix innovation framework, BALL engages all relevant stakeholders -older persons, caregivers, health and social care providers, third sector institutions, research and universities, and private companies- in this process. 
 The point of entry by which BALL gives a voice to citizens, older persons and caregivers is the “Thursday Appetizer” series, which consists of participatory sessions during which seniors and other stakeholders work together on generating ideas and defining how to implement and evaluate them. The mission of the project is to identify aging-related challenges at local and global levels and to develop potential solutions. A 3-session pilot phase is currently underway, following a waterfall methodology, with each session conditioning the following one. The first session focused on identifying general challenges related to aging. We followed a brainstorming methodology and classified all challenges identified into four categories: digital gap (connectivity and access to information), loneliness, age discrimination and the defense of the rights of older people, and planning for healthy and active aging. The second session focuses on prioritizing one of these groups and exploring possible solutions to face that specific challenge, again adopting a brainstorming methodology. The third session, then, focuses on these solutions in greater depth, comparing and contrasting them and analyzing strengths and weaknesses and commonalities and differences, with the goal of eventually co-creating a specific product or service. If needed, experts in the area of the challenge being tackled will be invited to participate in future “Thursday Appetizer” sessions.
 Once the pilot stage is finished, we will provide feedback to participants by sending them a wrap-up of the three sessions, as well as a personalized thank you letter including information regarding resources appropriate to their needs. Furthermore, we will conduct an evaluation of the impact and viability of the pilot in order to co-design a scale-up strategy for 2023, along with participants and the rest of stakeholders. Results of this initiative will be openly published on the BALL website (www.ballaginglab.org) and disseminated in order to increase the social awareness and to attract additional participants. Our long-term objective is to turn the “Thursday Appetizer” series into the breeding ground of innovative products and services co-created by BALL. This way, we will ensure that the solutions we propose adequately respond to real needs from the very beginning. 
 By including the views of end users from the very beginning, we expect to shorten the delay between the detection of needs and the social return on innovation in aging.

NGHIÊN CỨU XÂY DỰNG THIẾT BỊ HỖ TRỢ QUÁ TRÌNH LUYỆN TẬP PHỤC HỒI CHẤN THƯƠNG CỔ TAY

In this paper, we develop a supportive device to monitor the rehabilitation exercise process for people with disabilities to use their hands. The prototype is designed to include a resistance cable system to support the rehabilitation of the patient's hand motor function. During training, the patient pulls the resistance cable to exercise, and the resistance cable system applies force to the product's sensor block. The sensor block is capable of measuring parameters when force is applied, allowing the calculation of hand force during the patient's training. The hand force data obtained from the sensor block is then sent to a separate IoT-based application. This mobile-platform app is particularly developed for hosting data and providing a view for user to track his/her process of training. Additionally, the product is designed with angle measurement capabilities to track motion coordinates during the patient's hand training. The product is tailored to the physique of Vietnamese individuals. The patient's training results are stored on the Internet and displayed on a mobile application, facilitating the monitoring of training progress, comparing patient training results with standard data, and allowing remote monitoring by the patient's family members or healthcare professionals.

Online English Monolingual Learner’s Dictionaries

Due to the development of technology, well-established publishers began to provide their English Monolingual Learner's Dictionaries (MLDs) online and free of charge. Dictionaries of this type have their own history, as well as common and distinctive features. The article presents a brief outline of the subsequent stages of the development of English Monolingual Dictionaries, with special reference to MLDs available online. Also, the article includes a synthetic description of the primary and secondary components of a dictionary entry and demonstrates if these components are present or absent in three online Monolingual Learner's Dictionaries: the Cambridge Dictionary, the Longman Dictionary of Contemporary English, and the Oxford Learner’s Dictionary. The article aims to characterise, compare and contrast some of the features of a typical entry in online English MLDs. Consequently, the scientific approach adopted in the analysis is a mixture of the comparative and the empirical method. Unlike previous topic-related research, the present study shows both common and distinctive features of the mentioned dictionaries and hints at their practical advantages (from the point of view of the end user).

Acceptability and concerns about innovative wearable health sensors in persons with and without chronic disease diagnosis

Advances in biomedical engineering continue to produce innovative wearable health sensors capable of real-time ambulatory assessments (e.g., of physiology, the environment), holding great potential for advancing precision monitoring and interventions through the integration of such devices and data into eHealth systems. As with any novel device, however, user views on acceptability and concerns about the technology must be evaluated to facilitate widespread implementation and user adoption of such devices. One factor that may strongly influence user views is the potential relevance to, and need for, self-care for chronic disease management. We examined if acceptability and concerns regarding innovative wearable devices differed between individuals living with or without chronic disease. A U.S. adult sample (N = 448; 20-70 yrs.; 34 % Female; 60 % White, 35 % Hispanic) completed a web-based survey regarding their thoughts/opinions related to innovative wearable sensors. Two-thirds (67 %, N = 298) reported at least one chronic disease; one-third (33 %, N = 150) reported no chronic health conditions. Participants viewed learning modules about two innovative devices: a watch to detect environmental gases for respiratory health, and a chest-patch monitoring real-time ECG. For each device, participants rated acceptability across multiple dimensions, and then rated potential concerns (including general concerns and specific worries about negative health impacts). Respondents with and without chronic disease differed in education, race, and ethnicity. Controlling for these differences, individuals with chronic disease reported significantly higher acceptability for the watch and for the chest-patch. Healthy participants reported significantly higher general concerns about technology. However, when concern questions were asked specifically about the potential negative impacts of the two study devices on physical health and well-being, participants with chronic disease reported significantly higher concerns. Overall, results show that living with chronic disease influences acceptability and concerns associated with adoption of innovative sensors. These findings suggest it is essential to take potential users' health status into account when studying the design and implementation of innovative wearable sensors. Dissemination strategies may benefit from emphasizing the beneficial features of these devices, addressing hesitations, and customizing implementation approaches by user group.

The Role of Augmented Reality Neuronavigation in Transsphenoidal Surgery: A Systematic Review.

In the field of minimally invasive neurosurgery, microscopic transsphenoidal surgery (MTS) and endoscopic transsphenoidal surgery (ETS) have been widely accepted as a safe approach for pituitary lesions and, more recently, their indications have been extended to lesions at various skull base regions. It is mandatory during transsphenoidal surgery (TS) to identify key anatomical landmarks in the sphenoid sinus and distinguish them from the lesion. Over the years, many intraoperative tools have been introduced to improve the neuronavigation systems aiming to achieve safer and more accurate neurosurgical interventions. However, traditional neuronavigation systems may lose the accuracy of real-time location due to the discrepancy between the actual surgical field and the preoperative 2D images. To deal with this, augmented reality (AR)-a new sophisticated 3D technology that superimposes computer-generated virtual objects onto the user's view of the real world-has been considered a promising tool. Particularly, in the field of TS, AR can minimize the anatomic challenges of traditional endoscopic or microscopic surgery, aiding in surgical training, preoperative planning and intra-operative orientation. The aim of this systematic review is to analyze the potential future role of augmented reality, both in endoscopic and microscopic transsphenoidal surgeries.

Need Analysis Course Design: ESP Textbook Evaluation in The Psychology Faculty

This study aims to describe the 'need analysis' of English for Psychology courses and evaluate the ESP textbook from the point of view of the textbook users at the Faculty of Psychology. A need analysis survey in learning ESP and ESP textbook evaluation was conducted and then analyzed quantitively. The data sources of this research were students of the Faculty of Psychology who were taken by purposive sampling, which amounted to 20 people already in the 4th, 6th, and 8th semesters, the head of the Psychology department, and three lecturers in the Psychology Faculty. The data collection used was a questionnaire and documentation. The data is in the form of questionnaire results and interviews. Documentation technique is used in collecting data, while analysis technique is used in analyzing data, namely reduction, data display, and drawing conclusions and verification. The study results show that language skill materials are crucial for future Psychology students.
 Regarding speaking skills, students primarily require resources for conversing with current issues that are up-to-date. Regarding the students' need to access psychology journals and textbooks, writing and skills in composing scientific articles, reports, and lab documents are essential. However, the study reveals dissatisfaction among Psychology students with the current ESP textbook, particularly in appearance, visuals, design, layout, and writing materials. Despite some elements meeting their needs, such as layout, content, exercises, and speaking resources, improvements are needed in certain areas. Consequently, it is recommended that the ESP textbook be enhanced to better cater to these requirements, and future researchers undertaking similar studies should consider this focus on English for Specific Purposes (ESP).

Analysis of the Saliency of Color-Based Dichoptic Cues in Optical See-Through Augmented Reality.

In a future of pervasive augmented reality (AR), AR systems will need to be able to efficiently draw or guide the attention of the user to visual points of interest in their physical-virtual environment. Since AR imagery is overlaid on top of the user's view of their physical environment, these attention guidance techniques must not only compete with other virtual imagery, but also with distracting or attention-grabbing features in the user's physical environment. Because of the wide range of physical-virtual environments that pervasive AR users will find themselves in, it is difficult to design visual cues that "pop out" to the user without performing a visual analysis of the user's environment, and changing the appearance of the cue to stand out from its surroundings. In this article, we present an initial investigation into the potential uses of dichoptic visual cues for optical see-through AR displays, specifically cues that involve having a difference in hue, saturation, or value between the user's eyes. These types of cues have been shown to be preattentively processed by the user when presented on other stereoscopic displays, and may also be an effective method of drawing user attention on optical see-through AR displays. We present two user studies: one that evaluates the saliency of dichoptic visual cues on optical see-through displays, and one that evaluates their subjective qualities. Our results suggest that hue-based dichoptic cues or "Forbidden Colors" may be particularly effective for these purposes, achieving significantly lower error rates in a pop out task compared to value-based and saturation-based cues.

Representation of Chuvash ethnicity in cyberspace

The article examines the forms, methods and mechanisms of representation of Chuvash ethnicity in cyberspace, characterizes the space of ethnic history and culture of the Chuvash on the Internet, describes the forms and ways of representing the ethnic image of the Chuvash in the Internet space, analyzes the structure of Chuvash cyberspace; characterizes the degree of activity and motivation of participants in virtual communities in the process of representation of ethnicity. The research is based on the study of the content of the «Chuvash» Internet: online platforms, Internet services, resources, a virtual «field» – an online survey of users of social networks. The study showed that cyberspace reflects the real picture of ethnocultural processes in the Chuvash world, in particular in the field of communication, demonstrates the functionality of elements of ethnic culture (songs, costume, etc.). At the same time, the global network is forming its own space of Chuvash ethnicity, based on markers that are significant from the point of view of Internet users (language, songs, visual images of Chuvash culture). By broadcasting them through social networks and web services to the real world, users construct their identity and form a cyberspace with significant potential for preserving the ethnicity of the Chuvash in the real world. Thanks to the content in Russian and other languages, the Chuvash culture and language are being popularized. At the same time, the activity of Chuvash Internet users in ethnocultural topics is low, and in most cases it is expressed by passive forms of information perception, which probably indicates the limited nature of the impact of virtual ethnicity on the processes of ethnic identification of Chuvash in reality.

Usability evaluation of emergency information systems in educational hospitals in Kerman, Iran

BackgroundSmart and practical health information systems and applications with fewer errors are crucial for healthcare facilities. One method that ensures the proper design of health information systems (HIS) and applications is usability evaluation.ObjectiveThis study aimed to evaluate the usability of the emergency information systems used at the emergency departments of four educational hospitals in Kerman, Iran.MethodThis study was conducted in two phases. In the first phase, the information systems' errors and shortages were identified using a semi-structured questionnaire by users (nurses and the IT staff). In the second phase, based on the results of the first phase, two questionnaires were designed for each group of users to their opinions about the usability of the emergency information systems.ResultsThe average score of “reducing and facilitating user’s daily activities” was significantly different among hospitals (p = 0.03). Shahid Beheshti Hospital obtained the lowest usability score (17.5), and Afzalipour Hospital received the highest usability score (21.75). Moreover, the average score in “use of the HIS” for nurses and IT staff was 2.93 and 3.54 on a scale of 5, respectively.ConclusionUsability evaluation of health information systems is essential to ensure that these systems provide sufficient and accurate information and requirements for users and health care providers. Also, modifying health information systems based on the user views and expectations improves the quality of the system and user-system Interaction.
