The objective of this research is to evaluate the usability test of 'Paldokangsan3' which has been developed as a serious game for the elderly to improve their physical and mental health. This game machine has been installed in a silver house for one month that the elderly could play the game as they like in their convenient times. To promote their participations to practice the game, we set 3 contests with gifts for the high scores and collect their data through inspection, questionnaire and interviews by the researchers as well as in-game measurement for the play. Eight people volunteered to join the project. While the result analysis for the usability area of easiness of control, learnability of the game play, memorability and challenge didn't show the statistical confident t-value, most elderly players participated 2~3 times a day for a month even though most of them are suffering mild cognition impairment. They showed good subjective satisfactions in their interviews that we could go on the project further to expand its applications.
The primary aim of this study was to compare responsiveness of self-report by worker and therapist-scored functional capacity instrument. Self-report and therapist-scored interval-level person measures and item difficulties were compared at admission and discharge. Therapist and worker ratings were collected on 230 clients from 27 rehabilitation sites using the newly developed Occupational Rehabilitation Data Base (ORDB) functional capacity instrument. ORDB comprises several subscales measuring relevant variables of "a return-to-work model" in work-related rehabilitation clinics. The functional capacity scale deals with 10 DOT job factors. The rating scale categories were 1-severely impaired, 2-moderately impaired, 3-mildly impaired, and 4-not impaired. Only data from clients with low back pain (n=98) with complete data (both admission and discharge scores) were used for the present study. Therapists and workers completed the functional capacity instrument at admission and discharge. Rasch analysis [1-parameter item response theory model (IRT)] was applied to calibrate item difficulty and person ability measure of therapist and workers ratings. Effect sizes for therapist and self-report ratings were slightly different, .69 and .30, respectively. Therapist and worker ratings were more consistent at discharge (r=.54) than at admission (r=.32). Workers have a tendency to be more severe in their ratings (show higher item difficulties) than therapists at admission and discharge. Therapists and workers report similar magnitudes of improvement following treatment program. These findings challenge the belief that injured workers may unreliable source for monitoring therapeutic outcomes. Self-report measures have the advantage of conserving therapist time for treatment (versus evaluation). While the therapist and self-report ratings are comparable at discharge, there is less consistency at admission. Comparable therapist-worker ratings may be achieved by controlling for rating severity using IRT methodologies.

This paper provides theoretical background on the relationship between social worker's Job satisfaction and Self-efficacy for Empirical Search. According to previous researches, the more social workers feel self-efficacy the better they select their jobs actively and work very hard. In addition, they are more likely to challenge constantly and have more possibility to carry out their tasks successfully. However, it is assumed that there are theoretical differences in Social Welfare Area compared with other Social Science Area due to the particularity of Social Worker's Job and tasks. Therefore, the aims of this paper is to review theoretical background on the relationship between Job Satisfaction and Self-efficacy in other Social Science Area and provide the groundwork for the expansion of Social Work Practice Research Area through Empirical Analysis in the future.

In 2018, The Ministry of Health and Welfare announced its first comprehensive plan for patient safety, which included the imperative to develop a patient safety curriculum for students studying to become health professionals. The aim of this study is to assess current patient safety education and points of consideration for introducing new curriculum. An online survey was used to understand the status of patient safety education in medical schools, and key informant interviews and focus group interviews were used to collect qualitative data on the experience of patient safety education. The results of the online survey from 16 out of 40 medical schools (40% response rate) and the qualitative data analysis were integrated and analyzed. Twelve schools (75%) had established courses related to patient safety. The qualitative responses suggest that patient safety education is appropriate both before and after clinical training through a variety of educational methods, and that the topics should be linked with clinical training. The challenge of securing lecture time to address patient safety was mentioned as a realistic obstacle. When patient safety education is integrated in future curriculum, it is necessary to consider it as a priority. Moreover, in the early stages of introducing patient safety education, a step-by-step, policy-based approach is required for seamless adoption and settlement.
The use of computational fluid dynamics (CFD) is becoming an increasingly popular means to model wind flows in and around buildings. The first published application of CFD to both indoor and outdoor building airflows was in the 1970's. Since then, CFD usage has expanded to include different aspects of building design. Wind tunnel testing (WTT) on buildings for wind loads goes back as far as 1908. Gustave Eiffel built a pair of wind tunnels in 1908 and 1912. Using these he published wind loads on an aircraft hangar in 1919 as cited in Hoerner (1965 - page 74). The second of these wind tunnels is still in use today for tests including building design ($Damljanovi{\acute{c}}$, 2012). The Empire State Building was tested in 1933 in smooth flow - see Baskaran (1993). The World Trade Center Twin Towers in New York City were wind tunnel tested in the mid-sixties for both wind loads, at Colorado State University (CSU) and the [US] National Physical Laboratory (NPL), as well as pedestrian level winds (PLW) at the University of Western Ontario (UWO) - Baskaran (1993). Since then, the understanding of the planetary boundary layer, recognition of the structures of turbulent wakes, instrumentation, methodologies and analysis have been continuously refined. There is a drive to replace WTT with computational methods, with the rationale that CFD is quicker, less expensive and gives more information and control to the architects. However, there is little information available to building owners and architects on the limitations of CFD for flows around buildings and communities. Hence building owners, developers, engineers and architects are not aware of the risks they incur by using CFD for different studies, traditionally conducted using wind tunnels. This paper will explain what needs to happen for CFD to replace wind tunnels. Ultimately, we anticipate the reader will come to the same conclusion that we have drawn: both WTT and CFD will continue to play important roles in building and infrastructure design. The most pressing challenge for the design and engineering community is to understand the strengths and limitations of each tool so that they can leverage and exploit the benefits that each offers while adhering to our moral and professional obligation to hold paramount the safety, health, and welfare of the public.
Unmet healthcare is an important indicator to measure accessibility of healthcare services. To examine the latest status of unmet healthcare needs in South Korea, four different data which is composed of nationally representative sample of South Korean population were used; the Korea National Health and Nutrition Examination Survey (KNHANES, 2007-2020), the Community Health Survey (CHS, 2008-2020), the Korea Health Panel Survey (KHP, 2011-2018), and the Korean Welfare Panel Study (KOWEPS, 2006-2020). The proportion of individuals reporting unmet healthcare needs were 6.4% (KNHANES), 5.4% (CHS), and 12.2% (KHP). Annual percentage change (APC) which identifies trend for the follow-up period was -9.9%, -9.1%, and -5.5%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.0% (KNHANES), 0.4% (CHS), 2.2% (KHP), and 0.4% (KOWEPS). The APC was -11.3%, -17.0%, -12.2%, and -21.2%, respectively. Overall, the low-income and the elderly population reported a higher rate of unmet health care needs. Although the overall experience rate of unmet medical care due to cost decreased over the past decade, the disparity between the lowest and highest income groups still remained in 2020. Disparity between income levels and age groups is a challenge to address in healthcare system, and these results suggest the need for adequate health coverage for the low-income and the elderly populations.

The purpose of this study was to describe the family life and relationships of national family center users in 2023. A sample of 1,086 adults was recruited from 48 family centers across South Korea. Participants, both online and offline, reported on various aspects of family life, including satisfaction, gender equality, work-home-life balance, family leisure, and internet usage for family and household purposes. Additionally, family relationships were explored in terms of dynamics with a spouse, children, and adult children. Data were analyzed using descriptive statistics and t-tests. In the family life domain, center users reported a high level of satisfaction, with women exhibiting greater awareness of gender equality and higher engagement in household chores than men. Furthermore, although a moderate balance among work, home, and life was reported, time emerged as a significant challenge for family leisure. Regarding technology, center users frequently utilized the internet for family communication, leisure, shopping, and household management. In the family relationships domain, men were more satisfied with spousal relationships than women. Center users reported high satisfaction with parent-child relationships. Parents of school-aged children perceived economic burdens, while those with adult children frequently provided psychological and instrumental support. These findings suggest the need for program modification and the development of new initiatives within national family centers to better support the diverse needs of families in terms of life satisfaction and relationship dynamics.

This study analyzed the effects of social support on entrepreneurial opportunity competence for Baby boomer (born in 1955-1963), focusing on mediating effect of entrepreneurial self-efficacy. The governmental start-up policy and entrepreneurship education are mostly conducted for the college students and young generation mainly through such programs as the youth start-up school. In addition, studies on the effects of social support and institutional support on the entrepreneurial intention of young generation entrepreneurs are being actively pursued. Meanwhile, the study for baby boomers is on the welfare side mainly. Although they are starting to make their living-based business without prior careful preparation for their livelihood after retirement, while there is little study on the effect of social support for this baby boomer on entrepreneurial opportunity competence needed for opportunistic entrepreneurship. Therefore, in this study, in order to investigate the effect of social support on Baby boomer's entrepreneurial opportunity competence, an empirical analysis of the 387 questionnaires collected by the baby boomers living in Seoul and Gyeonggi provinces were conducted. As a result of analysis, First, Social support has a significant effect on both Opportunity recognition and Opportunity assessment of entrepreneurial opportunity competence. Second, In the effects of social support on self-efficacy were found to be significant in Emotional and Instrument support only on Self-confidence, In Emotional support and Feedback support only on Self-regulated efficacy & Emotional support and Instrument support only on Goal challenge were found to be a significant effect. Third, Self-regulated efficacy and Goal challenge in the Entrepreneurial self-efficacy on Entrepreneurial opportunity recognition were found to be a significant effect. All Self-confidence, Self-regulated efficacy & Goal challenge in the Entrepreneurial self-efficacy on Entrepreneurial opportunity assessment were found to be a significant effect. Fourth, Indirect effect of social support on entrepreneurial opportunity competence mediated by Entrepreneurial self-efficacy was found to be partially significant.

The concept of “precision agriculture” or “site-specific farming” is usually confined to the fields of soil science, crop science and agronomy. However, because plants grow in soil, animals eat plants, and humans eat animal products, it could be argued (perhaps with some poetic licence) that the fields of feed quality, animal nutrition and animal production should also be considered in this context. NIR spectroscopy has proved over the last 20 years that it can provide a firm foundation for quality measurement across all of these fields, and with the continuing developments in instrumentation, computer capacity and software, is now a major cog in the wheel of precision agriculture. There have been a few giant leaps and a lot of small steps in the impact of NIR on the animal world. These have not been confined to the amazing advances in hardware and software, although would not have occurred without them. Rapid testing of forages, grains and mixed feeds by NIR for nutritional value to livestock is now commonplace in commercial laboratories world-wide. This would never have been possible without the pioneering work done by the USDA NIR Forage Research Network in the 1980's, following the landmark paper of Norris et al. in 1976. The advent of calibration transfer between instruments, algorithms which utilize huge databases for calibration and prediction, and the ability to directly scan whole grains and fresh forages can also be considered as major steps, if not leaps. More adventurous NIR applications have emerged in animal nutrition, with emphasis on estimating the functional properties of feeds, such as in vivo digestibility, voluntary intake, protein degradability and in vitro assays to simulate starch digestion. The potential to monitor the diets of grazing animals by using faecal NIR spectra is also now being realized. NIR measurements on animal carcasses and even live animals have also been attempted, with varying degrees of success, The use of discriminant analysis in these fields is proving a useful tool. The latest giant leap is likely to be the advent of relatively low-cost, portable and ultra-fast diode array NIR instruments, which can be used “on-site” and also be fitted to forage or grain harvesters. The fodder and livestock industries are no longer satisfied with what we once thought was revolutionary: a 2-3 day laboratory turnaround for fred quality testing. This means that the instrument needs to be taken to the samples rather than vice versa. Considerable research is underway in this area, but the challenge of calibration transfer and maintenance of instrument networks of this type remains. The animal world is currently facing its biggest challenges ever; animal welfare, alleged effects of animal products on human health, environmental and economic issues are difficult enough, but the current calamities of BSE and foot and mouth disease are “the last straw” NIR will not of course solve all these problems, but is already proving useful in some of these areas and will continue to do so.

Even after Fukuyama declared "The End of History" in 1989, the challenge to liberal democracy continues. Controversy about totalitarianism is constantly being raised both internally and externally in democratic countries and leaders, as well as the US-China war of supremacy. In this paper, I explored a hypothesis about the totalitarian process, and to explain this hypothesis, I analyzed the case of Venezuela, which was once referred to as a welfare model state. This paper presupposes Fukuyama's insistence on the universality of liberal democracy but considers the last man Nietzsche argues for the last man he assumes. Accordingly, the process of totalitarianism was viewed as a process in which totalitarianism was institutionalized and spread internationally through the linkage and interaction of the last fallen humans, the masses, and totalitarians in the international and domestic environments. According to this hypothesis, the Bol?var Revolution and Chavez show the process of transformation into a typical quasi-totalism. Although the Venezuelan people preferred democracy, they remained the last man who had become a man of "rich consciousness." While investigating this hypothesis, it was confirmed that extensive and interdisciplinary studies such as digital t otalitarianism and the development of science and technology should be followed.
