In this study, data from the 11th year of the Korean Welfare Panel Study (2016), the 12th year (2017), the 13th year (2018), and the 14th year (2019) were used to verify whether drinking problems in adults had an end-to-end effect on depression. The analysis showed that, first, the initial value of depression has a static (+) relationship with the initial value of problem drinking, and a significant relationship with the rate of change in problem drinking. Second, the supply and demand households showed a static relationship with the initial value of depression, the initial value of problem drinking. Third, in the case of people with disabilities, the relationship between the initial value of depression, the initial value of problem drinking, and the amulet (-). Therefore, it was suggested that the development of drinking problem prevention programs and education should be actively carried out in school education before adulthood.

The purpose of this study is to investigate the effects of peer attachment, self-esteem, and school life adjustment on the sense of community in the first grade of middle school adolescents. This study utilized the Korean Children and Youth Panel Survey(KCYPS) data(7th, 2016) to get more comprehensive and objective research result. A total of 2,000 subjects were included in the study. For statistics on the collected data, descriptive statistics, t-test, ANOVA, Pearsons' correlation and multiple regression analysis were performed using IBM SPSS statistics version 23.0. As a result of the study, the statistically significant variables affecting the sense of community in the first grade of middle school, were peer attachment and school life adjustment. The variable identified as having the greatest influence was school life adjustment. In order to inspire a sense of community, priority should be given to promoting school life adjustment.

This study aims to understand whether the effect of poverty is translated to adolescents' mental health though their exposure to violence, which is aggravated by the dangerous environments of the neighborhoods. For this purpose, the study analyzes whether poor adolescents tend to reside on neighborhoods with toxic environments, and whether living in the disadvantageous neighborhood causes the poor adolescents to experience greater violence victimization and fear of violence, and eventually, greater depression and anxiety. The study utilizes secondary analysis of longitudinal data of the Korea Youth Panel Survey. Structural Equation Modeling is used as an analysis method. The study results reveals that poverty has both direct and indirect effects on the level of adolescents' symptoms of depression and anxiety. Especially, poverty affects adolescents' depression and anxiety indirectly through increasing the possibility to reside in more dangerous neighborhoods. Explaining more in detail, living in dangerous neighborhoods seems to expose adolescents more to violence and fear of violence in the neighborhoods and this experience increases the level of depression and anxiety. The study argues that the negative effects of poverty on adolescents should be examined from the view of neighborhood environments. Finally, the study discusses the importance of increasing neighborhood competency as practice and policy implication.

In this paper, we examine how the market potential affects wages in the regions of Korea. Following Fallah et al.(2011), we construct a panel data set spanning from 2013 to 2020. After removing the characteristics that do not vary by region, changes in average wages were analyzed using a fixed effects model. Controlling for such region-specific characteristics as human capital, industrial structure, and population, the impact of market potential on wages was analyzed by first examining the entire group of cities in Korea, followed by just metropolitan areas and then small cities only. The regional wages are seen to increase across the board when the market potential improves. It was also found that, when the market potential increases, the resulting wage hike of small cities tends to be greater than that of large metropolitan areas.

This study aims to analyze the secondary data of disease distribution and medical service behavior according to gender and income by using the 17th wave data of the Korea Welfare Panel, which is being distributed in April 2023. Data for 7,865 people of raw data generated using the R language were collected, and among them, missing values (NA, - 2,012) were analyzed for 5,853 people. For analysis, average income by health status and gender, relationship with chronic diseases, outpatient visits to medical institutions by gender/age group, type of medical institution used by age group, and annual health checkup usage rate by gender/age group were examined. Through this, the medical utilization rate was higher in men than in women, and the utilization rate of hospitals and clinics was high.

최근 디지털 카메라의 인기가 높아지고 있다. 디지털 카메라의 경우 사진을 인화하여 보관하기보단 다른 디지털 매체에 데이터를 보관하는 방식이 더 유용하다. 최근 등장한 전자액자는 사진 데이터를 보관하고 감상하는데 매우 유용한 매체이고 LCD 패널 및 메모리의 가격 하락과 맞물려 대중화가 가능해졌다. 그리고 제조기술의 발달로 점점 많은 기능을 갖춘 전자액자가 출품되고 있다. Mark Weiser에 의해 처음 거론된 유비쿼터스는 물리 공간에 존재하는 모든 것이 컴퓨팅과 통신이 가능하도록 하여 인류의 삶을 더욱 윤택하게 하는데 목적이 있다. 본 논문에서는 사회적으로 부각되고 있는 유비쿼터스 기술과 조화를 이룰 수 있는 전자액자를 설계하고 구현하였다.

In this study, the integrated control and safety management system for a super-large LNG membrane storage tank has been presented based on the investigation and analysis of measuring equipments and safety analysis system for a conventional LNG membrane storage tank. The integrated control and safety management system, which may increase a safety and efficiency of a super-large LNG membrane storage tank, added additional pressure gauges and new displacement/force sensors at the steel anchor between an inner tank and a prestressed concrete structure. The displacement and force sensors may provide clues of a membrane panel failure and a LNG leakage from the inner tank. The conventional leak sensor may not provide proper information on the membrane panel fracture even though LNG is leaked until the leak detector, which is placed at the insulation area behind an inner tank, send a warning signal. Thus, the new integrated control and safety management system is to collect and analyze the temperature, pressure, displacement, force and LNG density, which are related to the tank system safety and leakage control from the inner tank. The digital data are also measured from measurement systems such as displacement and force of a membrane panel safety, LNG level and density, cool-down process, leakage, and pressure controls.

The purpose of this study was to raise validity of the result through using national data, to analyze the effect of children's smartphone addiction on aggression and moderating effect of parenting styles on the relationship between children's smartphone addiction and aggression. The data were obtained from 4th waves of KCYPS(Korean Children Youth Panel Study), and 1,686 4th graders in elementary schools who have smartphone were analysed. To achieve the purpose, this study executed frequency analysis, descriptive statistic, and hierarchical multiple regression analysis through SPSS 21.0. The results of this study are as follows: First, the higher children's smartphone addiction level, the higher children's aggression goes. Second, parents' supervision, affection, neglect have moderating effects on the relationship between children's smartphone addiction and aggression which means parenting styles could reduce children's aggression despite serious smartphone addiction. Based on these results, this study suggests that the combination of preventive discipline of smartphone addiction and parental education program is needed to reduce children's aggression which is main factor of bullying. In addition, this study suggests the establishment of special arrangement such as 'shut down' for smartphone addiction prevention.
