Purpose: The purpose of this study is to construct and verify a path model for the influencing factors on occupational stress of Vietnamese migrant workers in Korea. Methods: Participants were 193 Vietnamese migrant workers recruited from Foreign Workers Support Centers. Data were collected by a self-administered survey with copies of a Questionnaire written in Vietnamese. Data were analyzed with descriptive statistics, Pearson's correlation coefficients and path analysis using SPSS/WIN 23.0 and Amos 20.0 program. Results: Length of residence, homeland friends' and Korean colleagues'supports, and acculturation have been found to have significant direct effects on occupational stress of Vietnamese migrant workers. Meanwhile, Length of residence, homeland friends', Korean colleagues', and their families' supports showed indirect effects on their occupational stress. What had the greatest direct effect on occupational stress of Vietnamese migrant workers was Korean colleagues' support. Conclusion: For reducing occupational stress of Vietnamese migrant workers, it is necessary to strengthen their Korean colleagues' supports in work places. In addition, community organizations should take strategies to enhance homeland friends' supports and to improve acculturation of Vietnamese migrant workers.

Purpose: The purpose of this study is to identify the spatial distribution of hypertension prevalence and to investigate individual and regional-level factors contributing to the prevalence of hypertension in the region. Methods: This study is a cross-sectional research using the 2015 Community Health Survey. Total 64,473 people from 7 metropolitan cities were used for the final analysis. Geoda program was adopted to identify the regional distribution of hypertension prevalence and analyzed by descriptive statistics, one-way ANOVA and correlation analysis using SPSS statistics 23.0 program. Multi-level analysis was performed using SPSS (GLMM). Results: The prevalence of hypertension was related to individual level factors such as age, monthly household income, normal salt intake, walking practice days, and regional level factors including number of doctors per 10,000 population, number of parks, and fast food score. Besides, regional level factors were associated with hypertension prevalencies independently without the effects of individual level factors even though the influences of individual level factors ware larger than those of regional factors. Conclusion: Respectively, both individual and regional level factors should be considered in hypertension intervention programs. Also, a national level research is further required by exploring various environmental factors and those influences relating to the hypertension prevalence.

Purpose: The aim of this study is to identify core keyword of frailty research in the past 35 years to understand the structure of knowledge of frailty. Methods: 10,367 frailty articles published between 1981 and April 2016 were retrieved from Web of Science. Keywords from these articles were extracted using Bibexcel and social network analysis was conducted with the occurrence network using NetMiner program. Results: The top five keywords with a high frequency of occurrence include 'disability', 'nursing home', 'sarcopenia', 'exercise', and 'dementia'. Keywords were classified by subheadings of MeSH and the majority of them were included under the healthcare and physical dimensions. The degree centralities of the keywords were arranged in the order of 'long term care' (0.55), 'gait' (0.42), 'physical activity' (0.42), 'quality of life' (0.42), and 'physical performance' (0.38). The betweenness centralities of the keywords were listed in the order of depression' (0.32), 'quality of life' (0.28), 'home care' (0.28), 'geriatric assessment' (0.28), and 'fall' (0.27). The cluster analysis shows that the frailty research field is divided into seven clusters: aging, sarcopenia, inflammation, mortality, frailty index, older people, and physical activity. Conclusion: After reviewing previous research in the 35 years, it has been found that only physical frailty and frailty related to medicine have been emphasized. Further research in psychological, cognitive, social, and environmental frailty is needed to understand frailty in a multifaceted and integrative manner.

Purpose: The purpose of this study is to identify the dietary habits of Korean adolescents and to investigate their effects on sleep duration. Methods: This study is a secondary analysis drawn from the 2016 Korean Youth Risk Behavior Web-Based Survey (N=65,528). ANCOVA was used to determine the relationship between dietary habits and sleep duration. Ordinal logistic regression was used to find out the effects of dietary habits on sleep duration adjusted for general characteristics and behavioral characteristics. Results: The group that consumed no breakfast (AOR=0.89, p<.001) had less sufficient sleep duration than those who had breakfast 7 times per week. The group that had drunk no milk (AOR=0.88, p<.001) had less sufficient sleep duration than those who enjoyed it 5 times per week. On the contrary, the groups that had no soda drinks (AOR=1.18, p=.015), caffeine drinks (AOR=1.77, p<.001), and sweet drinks (AOR=1.25, p<.001) were more likely to have sufficient sleep duration than the groups that consumed those beverages 5 times per week. Conclusion: It is important to educate adolescents about healthy eating habits including drinks and optimal sufficient sleep duration through a multidisciplinary approach.

Purpose: The purpose of this study is to identify trends in research on cultural competency of nursing students and nurses in Korea and to provide suggestions for future studies. Methods: A literature search was conducted with 432 papers published between 1985 and 2016 from five electronic databases and other sources using such key words as 'cultural competency', 'cultural nursing', 'multi-cultural competency', 'nursing students', 'nurses', etc. Results: The research design of 86 nursing researches on the cultural competence of nurses and nursing students analyzed in this study was 90.7% in quantitative research, 9.3% in qualitative research, and 2.3% in mixed research. Cultural competence was the most measured concept. A total of 41 papers (47.7%) out of 86 papers were used to measure cultural competence. Ten different tools were used various instruments of cultural competency were used in 41 papers. In 11 experimental studies, new methods such as role playing, case study, four stage 3D puzzle model, newspaper reading, and writing reflection note were used other than traditional method of lecture. Conclusion: The overall findings of this study suggest that future research should include more well-designed experimental studies, qualitative studies and repeated studies to confirm the effects of findings from previous studies. Development of effective and highly diverse teaching methods is recommended to increase cultural competency. Supporting systems and funding are required to help activate research of nurses.

Purpose: The purpose of this study is to investigate adherence to the clean intermittent catheterization (CIC) and influencing factors on the adherence following a customized intensive education program (CIEP). Methods: This work is a retrospective descriptive study. The subjects were 226 emptying failure patients who learned in a CIEP from January 2012 to July 2014. The program developed in 2011 and consisted of 1) customized theoretical education; based on the results of urologic tests, underlying disease, or surgery of the patients, 2) hands-on practice until the trainees were able to master the techniques, 3) questions about the process of catheterization and what he/she needs to know. 4) at follow-up, the survey about adherence and barrier to CIC. Clinical characteristics; the level of satisfaction, understanding, and self-confidence; the barrier in medical records were reviewed. Results: The short-term adherence rate (median 22 days) is 87.6% and the long-term adherence rate (median 112 days) is 50.4%. The biggest obstacle is time management. The levels of satisfaction, understanding, and self-confidence are very high. The variable of Income is the only factor that has influence on adherence. Conclusion: Despite the CIEP, the adherence rate is relatively low. In addition to the education, emotional and psychological supports and regular follow- up are needed to improve long-term adherence.

Purpose: The present study is focused on understanding weight perception related with individual- and school-level multifactorial origins, underestimated and overestimated respectively, in normal body weight adolescents. Methods: Using the 2017 Korea Youth Risk Behavior Web-based Survey data of 45,902 students from 799 secondary schools, a multilevel multinomial logistic regression analysis was performed where adolescents (level1) were nested within schools (level 2). Results: At the school level, the average school body mass index (BMI, kg/m2) and physical education were associated with weight perception among both boys and girls. In boys, geographic areas were associated with weight underestimation. At the individual level, perceived economic status, weekly allowance, BMI (kg/m2), smartphone usage time (hrs/day) and perceived stress were associated with weight perception among both boys and girls. Age, paternal education, academic achievement and alcohol use were associated with weight perception among girls, while part-time job and physical activity were associated with weight perception among boys. Conclusion: Our findings underscore the importance of individual- and school-level environments in developing correct weight perception and have implications for school health education to establish healthy lifestyle behaviors for all adolescents.

Purpose: This study was conducted to identify the influence of trauma experiences and social adjustment on health-related quality of life in North Korean defectors. Methods: The subjects were 117 North Korean defectors living in B and Y city. The data were collected from September 1 to September 20, 2014, and analyzed by the SPSS/WIN 18.0 program. Results: Significant differences were found in the health-related quality of life with respect to the subjects' education, marriage status, types of dwelling, family types, duration of residence in South Korea, jobs in South Korea and in North Korea, families left in North Korea or other surrounding countries, and subjective health status. Health-related quality of life is negatively related to trauma experiences during escape from North Korea and during their life in South Korea. Health-related quality of life positively is related to social adjustment. The meaningful variables which influenced the subjects'health-related quality include social adjustment, job in South Korea, job in North Korea, current family structure, and trauma experiences in South Korea. Total explanatory power of these factors for health-related quality in North Korean Defectors is 43.0% and social adjustment is the most influential factor. Conclusion: Therefore, in order to enhance health-related quality of life in North Korean defectors, it is necessary for them to increase social adjustment and decrease trauma experiences. In addition, methods are needed to provide job opportunities, better education and family services for North Korean defectors.

Purpose: The purpose of this study is to identify differences in disaster awareness, disaster preparedness, and nursing knowledge and practices between Korean and Japanese nursing students. Methods: The study subjects were 4th grade nursing students who completed their nursing education in Korea or in Japan. 359 students from Korea and 135 students from Japan participated in this study. Data were analyzed using IBM SPSS 21.0. The x2 test and the t-test were used to analyze the homogeneity of subjects' general characteristics and disaster-related characteristics. The comparison between the Korean and Japanese nursing students in disaster awareness, disaster preparedness, and nursing knowledge and practices were conducted using ANCOVA. Results: The Korean nursing students' disaster awareness, disaster preparedness, and nursing knowledge and practice were different from their Japanese counterparts'. The Korean nursing students recognized that the system of disaster management in Korea was insufficient and the negligence of management was one of the causes of the disaster. They wanted to participate in activities for disaster preparedness education and management. Conclusion: A disaster nursing curriculum dealing with disaster awareness, disaster preparedness, and nursing knowledge and practices, should be developed, implemented, and evaluated particularly for Korean nursing students.
