Purpose: Adolescents are vulnerable to depression; however, many health policies for adolescents tend to target students in schools. This study aims to identify factors related to depression according to gender among adolescents who have ceased attending school either temporarily or permanently. Methods: The data were generated from the 5th Dropout Youth Panel Survey (2017), and this study included 318 students in the survey that had dropped out of school. The data were analyzed using hierarchical multiple linear regression to identify related factors in depression among the participants. The analyses were performed by SPSS 25.0 program. Results: The depression scores of the students who had ceased attending school were: 20.28±5.47 for boys; 21.23±5.88 for girls. Their depression scores are significantly associated with self-esteem (p<.001 for boys; p=.001 for girls) and social stigma (p=.002 for boys; p=.002 for girls). Among those, peer attachment (p=.050), community integration (p=.004), and community disorder (p<.001) were significantly associated with depression only in boys. Conclusion: The findings of this study suggest that strategies for managing depression in adolescents who have dropped out of school should address the differences in contributing factors according to gender. This study also suggests a basis for approaching such a strategy.

Purpose: This study examined the reciprocal relationships between depression and income, and gender differences in these relationships among older adults in South Korea. Methods: Using 2015 to 2019 of the Korea Welfare Panel Study (KoWePS), we studied 6,070 older adults (2,394 men and 3,676 women) aged 60 years over in 2015. The generalized estimating equation was employed to explore the effect of an individual income on depression and the reverse causal link-that of depression on income. Results: The study found the reciprocal relationships between income and depression. Income has a significant impact on depression. Higher-income was linked to decreased risks of the Center for Epidemiologic Studies Depression (CES-D) scores among older adults (B = - 0.121, p < 0.001). Estimates of the reverse causal link show that higher CES-D scores were also linked to income reduction among Korean older adults (B = - 0.007, p < 0.001). In addition, we also observed gender differences in the impact of income on depression but not in the reverse causal link. Income has more detrimental to psychological consequence for older men (B = - 0.108, p < 0.001) than older women (B = - 0.057, p < 0.001). Conclusion: The finding implies that both psychological and social protection policies for the elderly are needed in view of gender perspective.

The purpose of this study was empirical verification of the effect of adolescents' truancy experience on the self-awareness and emotional problems. For this, using the data of 2016 in the Korean Children and Youth Panel Survey(KCYPS), we compared and analyzed using t-test and multiple regression analysis the self-awareness and emotional problems of adolescents who experienced truancy and adolescents who did not. As a result of the analysis, adolescents with truancy experience had relatively low self-awareness, and statistically significant but low scores in self-identity and career identity. However, there was a clear difference in emotional problems, and truancy adolescents scored high in attention, aggression, physical symptoms, and depression. This proved that adolescents with experience of truancy were more exposed to emotional problems, and it was necessary to develop a support system and program for this.

The purpose of this study is to analyse the longitudinal relations between creativity, academic achievements, and utilization of computer & smartphone of middle school students. For this purpose, multivariate latent growth model was verified, using three year longitudinal panel data of Seoul Educational Longitudinal Study(2013-2015). Results indicated that the more students in their first year used computer & smartphone, the better scores they obtained on the creativity and academic achievements. As their grade goes up, while the growth rates of using computer & smartphone and creativity were related positively, the growth rates of using computer & smartphone and academic achievements -even though it was not statistically significant- were related negatively. In addition, the first year students, who obtained high level of scores on the creativity, obtained high level of scores on academic achievements, but this tendency was not significant as their grade goes up.

Background: Humidifier disinfectant exposure is an ongoing issue, and there is still considerable related controversy. Various approaches are needed to secure scientific evidence on the extent of the victims' damages and for the determination of appropriate compensation. Objectives: The purpose of this study was to assess the association between humidifier disinfectant (HD) use and academic achievement in Korean children. Methods: This study used data from the 8th Panel Study on Korean Children in 2015. For the final study, 1,598 cases were used. T-tests and multiple linear regression analyses were conducted to determine whether the use of humidifier disinfectant is a factor that affects academic ability. Results: Children in groups using humidifier disinfectant showed statistically significantly lower scores in all areas of language, including reading, speaking and writing, and statistically lower scores in all areas of mathematics, including counting, addition and subtraction. In the multiple regression analysis results, which control for the effects of various demographic/social variables, the use of humidifier disinfectants showed statistically significant beta coefficients (β: -0.357, p<0.001), negatively affecting children's language ability. As for the 'math' variable, which was created by combining counting, addition, and subtraction scores, the use of humidifier disinfectants as independent variables also showed statistically significant beta coefficients (β: -0.200, p<0.001), negatively affecting children's math ability. Conclusions: The results of the study showed that depending on whether or not humidifier disinfectants were used, there are differences in children's language abilities, such as reading, speaking, and writing, as well as in their mathematical abilities, such as counting, adding, and subtracting numbers. These findings are thought to serve as a scientific basis for extending the perspective from health effects to more diverse areas of demographic and social impact related to humidifier disinfectant damage and compensation.

Purpose : To collect and interpret basic data involving the discomfort level of platelet donors and to see which nursing interventions would help make plateletpheresis more comfortable. Methods : Using "the Platelet Donor's Discomfort Scale" developed by the researcher herself and reviewed by an expert panel, the severity of discomfort as well as factors contributing to the development of this discomfort were analyzed. This scale contained 59 items and each item was scored by the 4-point Likert manner. Between March 1, 1996 and May 31, 1996, 500 platelet donors(16 years of age and older) were enrolled in this study. The Statistical methods used were factor analysis, t-test, and ANOVA. The results were as follows : 1. The mean of the platelet donor's discomfort scale was 130, range 69-207, possible score ranging from 59-236. 2. The platelet donor's discomfort scale had psychological, environmental, physical, and time-related factors. The time- related factor was the highest positive correlation with the development of the discomfort. 3. In looking at the psychological and environmental factors of the discomfort scores, the 16-20 age group had significantly higher ratings than those of the 26-30 age group. The students' group had higher scores than the soldier's group, and those who used the V-50, MCS -3P, or the PCS Plus machines had higher scores than those who used the COBE Spectra machine(P<.05, respectively), 4. In relation to the physical factor of the discomfort score, the youngest group felt significantly more discomfort, the student's group had a higher score than the soldier's group, and those who used the V-50, MCS-3P, or or the PCS Plus machines had higher scores than those who used the COBE Spectra machine(P<.05, respectively). 5. The time related factor of the discomfort score had the highest scores in every variable, however, statistically significant differences were not found between any of the variables(P>.05). Conclusion : Based on the above results, it can be oserved that the time-related factor was the most important factor influencing discomfort. The age and job of the donor, as well as the type of machine used, were significant variables in predicting the level of discomfort, regardless of psychological, environmental, and physical factors. This data could be used to determine nursing interventions that would relieve some of the discomfort of patients, as well as donors, undergoing plateletpheresis. Furthermore, consideration of the donor's time, introduction of a platelet donor pool system, publicity and education about platelet donation are required.

A study was conducted on the preparation of Ramyon using composite flours of raked barley (20 or 30%)-wheat(80 or 70%) in commercial plant scale and on the quality evaluation of Ramyon made from those flours. The naked barley(20%)-wheat(80%) flour gave acceptable Ramyon-making characteristics during the continuous Ramyon manufacturing process. The composite flours had a higher water absorption rate in kneading process and oil absorption value of the Ramyon product than those of wheat flour alone. Even though the Ramyon of composite flours showed a little inferior value compared with wheat flour alone in the cooking and texture characteristics, sensory panel scores of Ramyon indicated that the naked barley (20%)-wheat(80%) flour was acceptable in Ramyon.

Drawing from the Korean Child and Youth Panel Survey (KCYPS), this study examined the changes in romantic relationship engagement among Korean adolescents across the country over a three-year period and the effects of the individual, familial, and school characteristics on the experience. Panel logit analysis showed that Korean adolescents were more likely to be engaged in a romantic relationship as they became older. Male adolescents were more likely than their female counterparts to have a romantic partner. The higher scores of self-esteem increased the likelihood of adolescents to be in a romantic relationship. On the other hand, having an opposite-sex sibling, the level of parental warmth, and annual household income did not have a significant relationship with the chance of romantic relationship engagement. On the contrary, all school-related variables were statistically related to the odds of being in a romantic relationship. Going to a sex-mixed school increased the odds, whereas academic adjustment and conformity to school rules decreased the likelihood. In addition, the positive relationships with schoolmates and teachers were associated with a higher chance of having a romantic partner. Based on these findings, the implications, limitations, and future research directions were also suggested.
