Backgrounds: As the COVID-19 pandemic continues, the university students population is one of the high risk and vulnerable groups. This study analyzed the status of student's mental health, including anxiety and depression caused by COVID-19, and its related factors among a university students in Korea. Methods : Our study subjects included university students in Korea. The survey items included general characteristics, teaching methods, physical activity, eating habits (SDBQ-L), weight-related questions, general anxiety disorder-7(GAD-7), and depression symptoms checklist. Frequency analysis, chi-square test, and logistic regression analysis were performed and data was analyzed using R version 4.1.2 program. Results : The prevalence of anxiety complaints was 5.5%, while the prevalence of depression complaints was 30.8%. In the multivariable logistic regression analysis of factors influencing anxiety, anxiety occurred 19.081 times (95% confidence interval (CI): 2.352-154.807) in the group with unhealthy diet (p<0.01). While in the multivariable analysis to identify factors affecting depression, women were 2.607 times significantly higher (95% CI: 1.255-5.415) than men, 0.407 times (95% CI:0.197-0.840) for residents of the metropolitan area, 3.418 times higher (95% CI:1.633-7.198) for unhealthy dietary people, and 2.225 times higher (95% CI: 1.080-4.582) for weight gainers (p<0.05). The type of class had no effect. Conclusions: COVID-19 and its associated interventions had negative effects on the mental health status including anxiety and depression in university students in Korea.

Purpose: The purpose of this study was to describe the current status of utilization and costs of home health nursing care by the levels of medical institutes in Korea. Method: A secondary analysis of existing data was used from the national electronic data information(EDI) of 148 home health agencies for 6 months from May to Oct 2005 in total. Result: The 148 agencies had multiple services in cerebral infaction, essential hypertension, sequoia of cerebrovascular disease, type 2 diabetes mellitus, etc.. The highest 10 rankings of 76 categories of home health nursing services were composed of 96.4% of the total services, such as simple treatment, inflammatory treatment, urethra & bladder irrigation, inserting indwelling catheter etc., in that order. The highest 20 rankings of 226 categories of home examination services were composed of 77.0% of the total home examination services. In addition, the average cost of home health care per visit was 46,088 Won (${\fallingdotseq}$ 48 $, 1 $=960 Won). The costs ranged from 74,523 Won (${\fallingdotseq}$78 $, loss of chronic kidney function, N18) to 32,270 Won (${\fallingdotseq}$34 $, other cerebrovascular diseases, 167). Conclusion: Results suggest that client characteristics of hospital based HHNC are not different from community based HHNC or visiting nursing services for elderly. The national results will contribute to baseline data used to establish a policy for the home health nursing care system and education.

Network-based real-time multimedia applications require guaranteed performances of communication service. Also according to increased bandwidth and processing performance in the future high speed networks, it is possible to make multimedia real-time applications such as distributed real-time applications including video conference, medical imaging, and video education. These applications have characteristics of stringent performance requirements in terms of delay, delay jitter and maximum loss rate. This paper proposes a new delay control for Broadband networks with FCFS queueing. The delay control provides an alternative solution to a current problem in real-time communication; traffic distortion, which makes it difficult to meet such real-time requirements. In simulations, it shows that the proposed delay control can guarantee local and end-to-end delay.

유비쿼터스 사회(Ubiquitous Society)의 핵심기술인 RFID(Radio Frequency Identification)를 물류, 유통, 교통, 의료 등 다양한 분야에서 개발, 적용하는 연구가 활발하게 진행되고 있다. RFID를 이용하여 u-Campus, u-Library 등 유비쿼터스 교육환경을 마련해주는 연구들은 있으나 직접적으로 학습에 적용한 연구는 아직 미미한 실정이다. 따라서 본 연구에서는 RFID 태그와 리더의 무선통신 기술을 이용하여 학습자의 위치와 상황을 인지하고 그에 부합하는 영어 상황학습 서비스를 제공하고자 한다. RFID 시스템을 이용하기 위해 본 연구에서 제안하는 RFID 미들웨어는 기존의 범용 RFID 미들웨어와 달리 PDA 기반에서 동작하는 모바일 RFID 미들웨어로 필수 API를 중심으로 최적화하여 개발하였다.

Purpose: The purpose of this study was to identify the frequency and duration of primary health practitioners' work, and their job satisfaction, and to confirm differences in work and job satisfaction by type of primary health care post. Methods: Work frequency, duration of work, and job satisfaction were estimated by 371 primary health practitioners. Chi-square test and t-test were used to identify the differences in working patterns and job satisfaction by type of primary health care post. Results: Primary health practitioners were found to spend more time working with the elderly population than with students, pregnant women, children, people with disabilities, and multicultural families. Those in costal areas were more concerned with students than those working inland. In the latter group of practitioners, more time was spent working with patients with chronic diseases, pregnant women, women, children, multicultural families, and mental health clients. Also, the job satisfaction of inland primary health practitioners was significantly higher than that of costal practitioners. Conclusion: It is necessary to identify the characteristics of primary health practitioners' work, focusing on changes in the medical service environment. Furthermore, it is necessary to provide job training according to type of primary health care post, as practitioners' approaches should differ between posts.

Purpose: The present study was designed to understand the conceptual definition and attributes of the clinical critical thinking ability(CCTA) in nursing and to grasp the characteristics of clinical critical thinking abilities. Methods: The data were analyzed using the Hybrid model of Schwartz-Barcott and Kim(2000). Results: Having the skills and dispositions to think critically, CCTA refers to something that implies the cognizant ability to interpret contextual meanings, analyze the relationships between materials or circumstances, draw out the best conclusions, predict things using relevant information and evaluate the reliability of information and the strength of inference on the one hand and the emphatic disposition to be curious, open-minded, intellectually integral, systematic and creative and to reflect on things in contextual terms on the other. Conclusion: CCTA is characterized by clinical circumstances, such as guessing the reasons for facts, predicting things, connecting theory to practice and approaching individual situation in total terms as well as by the Korean circumstances, such as taking another person's perspective. Hence, this study proposes developing the tools to measure the clinical critical thinking ability and the strategies to improve the clinical critical thinking ability and seeking to verify their validity, on the basis of the findings.

The purpose of this study was to examine the factors influencing the attitude toward the increasing role of private health insurance(PHI). In the Korea Welfare Panel Data 2007, a sample of 1,675 (adjusted by weight value: 1,607) respondents on an opinion on promoting PHI was used in the study. With independent variables including socio-demographic characteristics, health status, health-related behavior, and opinions on welfare service, ordered-probit model was used to analyze the attitude toward PHI. Negative opinion on the increasing role of PHI were responded by 54.6%(n=877) of the respondents, whereas 22.2%(n=373) were positive and 23.2%(n=357) were neutral. Old people, the better off, those with worse self-assessed health status, and those having an experience of health examination tend to have the positive attitude toward the increasing role of PHI. Women, those with chronic diseases or disorders and those who do not agree that comprehensive welfare benefits reduce work incentive showed negative attitude toward PHI. When comparing the needs for PHI before and after medical utilization, ex-ante need tends to strengthen the tendency to support private health insurance. This study will contribute to the discussion on the optimal mix of public and private health insurance in Korea by a better recognition of attitude toward PHI and health care system.

While healthcare data sets include extensive information about patients, many researchers have limitations in analyzing them due to their intrinsic characteristics such as heterogeneity, longitudinal irregularity, and noise. In particular, since the majority of medical history information is recorded in text codes, the use of such information has been limited due to the high dimensionality of explanatory variables. To address this problem, recent studies applied word embedding techniques, originally developed for natural language processing, and derived positive results in terms of dimensional reduction and accuracy of the prediction model. This paper reviews the deep learning-based natural language processing techniques (word embedding) and summarizes research cases that have used those techniques in the health care field. Then we finally propose a research framework for applying deep learning-based natural language process in the analysis of domestic health insurance data.
