The purpose of this study was to investigate the effects of social support on career maturity and self-reliance of inmates in a juvenile reformatory. This survey was administered to the adolescents in S juvenile reformatory, which represents juvenile reformatory across the nation. Statistical analysis were performed using SPSS 22.0 for 115 complete responses. Results are as follows: First, the effects of social support on career maturity was found to be statistically significant, $R^2=.411$, p<.001. That is, support by friends and religious program personnel remained a significant influence on career maturity, after controlling for sociodemographic variables. Second, the effects of social support on self-reliance was also found to be statistically significant, $R^2=.520$, p<.001. It was shown that the support of friends and family as dependent variables, had statistically significant effects on self-reliance. The results of this study suggest the need to expand programs that reinforce support by friends, a meaningful variable, along with the need to seek and link available resources within the local community in order to build social support systems. It is also necessary to establish education and related organizations to provide effective socail support.

This study was conducted to review the literature and examine the factors related to problem behaviors among students of multicultural families in Korea. A systematic review of the literature was conducted using domestic documents retrieved through July 4, 2018 based on online searches of domestic databases (the Research Information Sharing Service, Korean Studies Information Service System and the National Diet Library). A total of 2,084 studies were searched, and 21 studies were used for analysis. The factors related to problem behaviors were related to individual factors (gender, school record, self-esteem, etc.), family factors (family type, parent support, mothers' enculturation stress, etc.) and environmental factors (friend support, teacher support, social support). The variables measured the problem behaviors among students of multicultural families were school life adjustment (10), psychological, social adjustment or maladjustment (4), and emotional problem behavior (3). Overall, the results indicate that social and policy efforts are needed to improve individual, family, and environmental factors based on more specific and consistent theoretical definitions related to problem behaviors among students of multicultural families in Korea.

The purpose of this study is to systematically analyze through structural relationship analysis the relationship between excessive smartphone use by adolescents and school adaption. A questionnaire was administered to 866 elementary, middle and high school students who are using smartphones SEM was applied to the analysis with the following results. First, the relationship between excessive smartphone use and school adaptation was not significant. Second, the relationship between social support and excessive smartphone use had significant influence. Third, there is a significant influence in the relationship between self-control and excessive smartphone use. Fourth, social support and self-control of adolescents had a direct influence on school adaptation. Fifth, social support and self-control mediate the relationship between smartphone overuse and school adaptation. Therefore, increasing the adaptability of adolescents requires efforts to firm social support system by expanding autonomous sense or self-control personally and mutual support in the family.

The purpose of this study was to identify the convergent influence of social awareness and health status on social support in Korean echo generation by using Korea adult psycho-social anxiety survey data. Korea adult psycho-social anxiety survey data were collected from August to September 2015 and included 1,653, who responded to the question regarding social support. The data were analyzed by t-test, chi-square and hierarchial multiple regression using SPSS WIN 23.0 program. The mean score of social support was 19.60. The influencing factors on social support were neighborhood relations, perceived class, euphoria, equality in society, stability in society, self Esteem, communication, and stress, respectively. Therefore, it is necessary to establish strategies to strengthen social support of echo generation. A more careful examination may be warranted.

Recent experiments show the existence of spacer grid improves the heat removal from the fuel rods during the reflood phase of LOCA. The local heat transfer within and downstream of the grid is increased due to the earlier quenching than rod surface, shattering of the entrained droplets into smaller ones which can be more easily evaporated and enhanced turbulent effect. Therefore, the consideration of these phenomena is necessary for the DFFB regime which prevails above the water level during the reflood. In this paper, droplet breakup model at spacer grid has been developed and incorporated into RELAP5/MOD2. Verification calculations are carried out for FEBA tests which examine the thermalhydraulic performance of grid spacer during reflood.

The purposes of this study were to examine the stress, quality of sleep, Social support according to Myes-Briggs Type Indicator(MBTI) personality type in nursing students. Structured questionnaires were used for survey with a convenience sample of 290 nursing students. Data were analyzed using descriptive statistics, t-test, Pearson's correlation coefficient, and multiple regression with SPSS/WIN 18.0. Extroversion preference(${\beta}=.23$, p=.047) in quality of sleep, thinking prefernce((${\beta}=.06$, p=.025) in tangible support, judgement preference(${\beta}=.24$, p=.014) in appraisal support and perception preference(${\beta}=-.21$, p=.011) in Self-esteem maintenance were significantly associated factors with stress. Therefore, intervention programs for managements of stress should include systematic and indivisual intervention through the convergence of departments, university and specialists in nursing students.

This study was conducted with the purpose of examining the effect of material deprivation on the subjective mental health of youth and the moderating effect of social support in these relationships. For this purpose, frequency analysis, descriptive statistics, correlation analysis, and moderating effect model were analyzed using the response data of 2,041 youth who participated in the '2021 Youth Social and Economic Survey'. As a result of the analysis, first, it was found that the material deprivation of youth negatively and significantly affects subjective mental health. Second, it was found that social support moderated the effect of material deprivation on the subjective mental health of youth. The results of this study show that in order to improve the subjective mental health level of youth, it is necessary to not only strengthen public policies and systems to prevent the situation of material deprivation of youth in advance, but also to strengthen the social support system by raising the level of social support.

The wind tunnel test is one of the essential processes in the development of guided missile systems, and various wind tunnel facilities exist depending on the test requirements, various conditions, and their purposes. The Ludwieg tube is very useful in the development of guided missile systems, and we have necessitated the upgrade of the Ludwieg tube in ADD to acquire various test requirements, such as high angle of attack, repeatability, and stability. In this paper, upgrading the nozzle, vacuum tank, and model support is suggested to improve the Ludwieg tube performance, and we demonstrate a result of the solution through pressure measurement.

In bone tissue engineering, polycaprolactone (PCL) is one of the most widely used biomaterials in the manufacturing of scaffolds as a synthetic polymer having biodegradability and biocompatibility. The strut width in the fabrication of scaffolds is an important part of tissue regeneration in in-vitro and in-vivo experiments, because it affects not only the pore size but also the porosity. In this study, we used polymer deposition system (PDS) and design of experiments (DOE) to explore the optimal process conditions to achieve a systematic and efficient scaffold manufacturing process, using temperature, pressure, scan velocity, and nozzle tip height as the parameters for the experiments. The aim of this research was to fabricate a 3D PCL scaffold having a uniform strut width of $150{\mu}m$ using DOE; it was proved that the strut width was constant in all the experimental groups by fabricating the PCL scaffolds according to various pore patterns as well as one pore pattern.
