This study investigated the effect of sleep duration on food and nutrient intake among adult Koreans. The effects of sleep duration on dietary patterns was studied in 7,370 Korean adults, aged 20 and older, who participated in the 1998 Korean National Health and Nutrition Survey in which the 24 hour recall method was used to estimate dietary intake. Sleep duration data from individual subject were collected by interview as a part of a behavior survey. Analysis of variance and Duncan's multiple range test were used to test the differences in food and nutrition intake and sleep duration. Food intakes of the male subjects were not significantly different among three groups. However, there were significant differences observed in intakes of beverage and alcohol among female subjects among the three groups. There were no significant differences observed for nutrient intake by sleep duration for either gender. Unlike the observation from European and American studies, food and nutrient intake of Korean subjects, in general, were not greatly affected by duration of sleep. This result may suggest that dietary habits of Koreans, as affected by sleep, are quite different from those of Europeans & Americans.

The impact of sound speed variability in the sea is the very important on acoustic propagation for the underwater acoustic systems. Understanding of the temporal and spatial variability of ocean sound speed in the sea around the Ieodo were obtained using oceanographic data (temperature, salinity). from the Korea Oceanographic Data Center, collected by season for 17 years. The vertical distributions of sound speed are mainly related to seasonal variations and various current such as Chinese coastal water, Yellow Sea Cold Water (YSCW), Kuroshio source water. The standard deviations show that great variations of sound speed exist in the upper layer and observation station between 16 and 18. In order to quantitatively explain the reason for sound speed variations, Empirical Orthogonal Function (EOF) analysis was performed on sound speed data at the Line 316 covering 68 cruises between 2002 and 2018. Three main modes of EOFs respectively revealed 55, 29, and 5% the total variance of sound speed. The first mode of the EOFs was associated with influence of surface heating. The second EOFs pattern shows that contributions of YSCW and surface heating. The first and second modes had seasonal and inter-annul variations.

The purpose of this study is to investigate the relationship between suicidal ideation among Korean adolescents and factors such as family conflict, cohesion, organization of family activities, expressiveness, independence, achievement orientation, depression, stress, and support of friends and teachers, according to the individual student's parental type. The study sample consisted of 1908 high school students in the 11th grade from the city of Inchon. The results showed that in both males and females, suicidal ideation was greater in students from single-parent families than two natural-parent families and greater in step-parent families than in single-parent families. As an exploratory study, the analysis of factors influencing suicidal ideation according to parental type showed that the study model accounted for 33.6% for students from two natural-parent families, 42.8% for students from single-parent families and 84.5% for students from step-parent families, of the variance in suicidal ideation. This indicates that the study model is more appropriate for application to students from single-parent and step-parent families. In addition, the study shows that the factors of influence and the way these factors make an influence tended to differ according to parental type. This indicates that in terms of predicting suicidal ideation, it is more effective to study students according to parental type than as a whole. It also indicates that it is ineffective to take the same approach in dealing with suicidal ideation for students with different parental types.

Objectives: This study investigated how income, duration of illness, social stigma, quality of sleeping, ADL and social participation related to Parkinson's disease(PD) predict depression in a conceptual model based on the International Classification of Functioning(ICF) model. Methods: The sample included 206 adults with idiopathic Parkinson's disease(IPD) attending D university hospital in B Metro-politan City. A structured questionnaire was used and conducted face-to-face interviews. The collected data were analyzed for fitness, using the AMOS 18.0 program. Results: A path analysis showed that the overall model provided empirical evidence for linkages in the ICF model. Depression was manifested by significant direct effects of social stigma(${\beta}=.20$, p<.001), quality of sleeping(${\beta}=-.40$, p<.001), ADL(${\beta}=-.20$, p<.01), and social participation(${\beta}=-.12$, p<.05), indirect effects including income(p<.05), duration of illness(p<.05). These variables explained 45.9% of variance in the prediction model. Conclusions: This model may help nurses to collect and assess information to develop intervention program for depression.

Purpose: The purpose of this study was to determine the difference in reported discharge learning needs between nurses and liver transplantation (LT) patients. Methods: The participants of this study were 40 patients discharged after LT at P University Hospital in Y City and 42 nurses in intensive care units and the ward. The data were collected for two months from December 1, 2012, to January 31, 2013, and were analyzed using descriptive statistics, Student's t-test and analysis of variance (ANOVA). Results: Patients earning a low income (p=.041), having no experience of hospitalization after LT (p=.023), and receiving information about LT from nurses (p=.003) indicated higher discharge learning needs. Among the items evaluated regarding discharge learning needs, "rejection symptoms or signs" were regarded to be more important by nurses than LT patients (p=.038). However, "management of other diseases after LT" (p=.003), "risk of recurrence" (p=.001), "food choices" (p<.001), "obesity prevention" (p=.020), "amount of exercise" (p=.007), and "ways to receive financial help"(p=.033), were thought to be more important by LT patients than nurses. Conclusion: There exist differences between LT patients and nurses with respect to their perceptions of LT discharge learning needs. Therefore, an individualized education program reflecting patients' conditions and learning needs rather than providing information uniformly needs to be developed.

Purpose: The purpose of this study was to develop a scale to assess immigrant women's needs for pregnancy and postpartum adaptation and to test the reliability and validity of the scale. Methods: To construct scale items, critical issues and difficulties associated with pregnancy and postpartum adaptation of immigrant women were identified and categorized through a literature review. Fifty-two scale items were constructed, and data for validity and reliability testing was collected with a questionnaire survey from 367 immigrant women. Data were analyzed with descriptive statistics, factor analysis, and reliability coefficients. Results: The final measurement scale to assess immigrant women's pregnancy and postpartum adaptation consisted of 48 items and 7 factors (adaptation to daily activity during pregnancy, cross-cultural understanding and personal respect, understanding of the process of pregnancy and delivery, baby rearing and family support, physical and emotional adaptation after childbirth, nutrition during pregnancy, and sexual life adaptation). The seven factors accounted for 64.26% of the variance, and Cronbach's ${\alpha}$ was .96. Conclusion: The scale developed by this study is a reliable and valid instrument and can be used to assess needs of pregnancy and postpartum adaptation and can be utilized in providing nursing interventions for immigrant women.

Purpose: The purpose of this study was to determine the effects of knowledge and attitude on self efficacy of cardiopulmonary resuscitation (CPR) in the fifth and the sixth grade of elementary school students. Methods: The participants were 242 elementary school students from A city. Data were collected from August 26 to August 27, 2013 using a questionnaire. Data analysis was performed by SPSS/WIN 19.0 using ANOVA, t-test, Pearson correlation and stepwise multiple regression. Results: Factors affecting on self efficacy to CPR were attitude (${\beta}=.54$), religion (${\beta}=-.16$), recognition (${\beta}=.15$) and knowledge (${\beta}=.13$). These factors explain 47.0% of the variance in self efficacy. Conclusion: The results of this study show that attitude to CPR has the strongest influence on efficacy. Based on the results of this study, we suggest that customized programs and further research by using 2010 guideline are needed to develop for elementary school students.

Purpose: The purpose of this descriptive study was to identify the impact of workplace bullying and LMX (Leader-Member Exchange) on turnover intention among nurses. Methods: The participants were 364 nurses from the Seoul metropolitan area who were attending a continuing education program. A structured questionnaire was used for data collection and data were analyzed using the SPSS/Window program. Hierarchical multiple regression analysis was performed to verify the effect of variables on turnover intention. Results: Higher workplace bullying was associated with higher turnover intention. Workplace bullying was negatively correlated with leader-member exchange. The most influential factors for turnover intention were LMX (${\beta}=-7.22$, p<.001), work load (${\beta}=2.96$, p=.003), and workplace bullying (${\beta}=2.64$, p=.009). These factors accounted for 28% of the variance in turnover intention. Conclusion: The study results indicate that there is need to develop strategies to prevent workplace bullying and cultivate a good relationship between nursing managers and nurses to lower nurses' turnover intention.

The purpose of this study is to investigate the level of role stress perceived by employed housewives working in sales departments, and further, to devise coping strategies that can help reduce stress resulting from their multiple roles The sample of this study consisted of married women who were working in sales departments, who have at least one child, and who live in the greater Seoul metropolitan area. A total of 343 out of 450 originally distributed questionnaires were used for the analysis in this study. The findings of the study are: 1 The housewives in sales departments felt stress most severely in their role as a mother. Next were the roles as a wife, housewife, daughter, daughter-in-law, and working woman, in that order. 2. It appeared that age and the motive for employment affected the overall level of role stress among housewives. The two variables (age and the motive for employment) explained about 23% of the variance. The younger they were the higher was the level of role stress. Also, if they were working for an economic reason (to support the family), they tended to be more stressed out. The results of this study could be utilized as baseline data for policy-making, consultation, and development of educational programs for housewives working in sales departments, an area that has hardly been explored.
