In this study, the relationship between students' out-of-school science experience and their view on the nature of science was investigated. The participants were 267 sixth graders, 281 eighth graders, and 307 tenth graders from schools in Seoul. A test of views on the nature of science which consists of five items concerning the purpose of science, the definition of scientific theory, the nature of scientific model, the tentativeness of scientific theory, and the origin of scientific theory was administered. Students' out-of-school science experiences were measured with a subscale of the modified Science Experience Survey consisting of seven items. The results indicated that no statistically significant relationship was found between students' out-of-school science experience and their view on the nature of science in sixth graders. In eighth graders, high level students in terms of out-of-school science experiences were found to possess more contemporarily epistemological view in the item concerning the nature of scientific model but more falsificationist view in the item concerning the tentativeness of scientific theory. High level tenth graders in terms of out-of-school science experiences exhibited more epistemologically sophisticated understandings of the nature of science than their counterparts in the items concerning the purpose of science, the definition of scientific theory, and the nature of scientific model.

The purpose of this study was to provide implications for social work practice by examining the influence of career barrier on smart-phone addiction through self-esteem and depression among out-of-school adolescents. Using data from the Panel Survey of School Dropouts conducted by the National Youth Policy Institute, this study examined the research questions by analyzing the direct and indirect influences of career barrier on smart-phone addiction with the PROCESS macro method. First, the results of this study showed that out-of-school adolescents' career barrier statistically significantly increased smart-phone addiction. Also, out-of-school adolescents' depression mediated the influence of career barrier on smart-phone addiction, but out-of-school adolescents' self-esteem did not mediate the influence. However, out-of-school adolescents' self-esteem and depression dual-mediated the influence of career barrier on smart-phone addiction. The level of career barrier decreased the level of self-esteem, and in turn increased the level of depression, and finally increased the level of smart-phone addiction. Based on the findings, practical strategies to address the smart-phone addiction of out-of-school adolescents were discussed.

The purpose of this study is to understand in depth the gambling experiences of delinquent juveniles who have dropped out of school and analyze the content and meaning of gambling experiences. Thus, utilized a Giorgi's phenomenological research method. Data was gathered through in-depth interviews, and the gambling experiences of six youths who are under juvenile law protective disposition were examined through a four-step analytic process. From the results, 6 parent components and 18 sub-components were derived. That is, "the temptation of close gambling", "trapped in the bridle of gambling", "deterioration of life", "damaged of non-official networks relationship", "corruption of existence" and "attempts to escape gambling" were appeared. These results are meaningful because they have allowed researchers to identify the essential meaning and experiential structure of delinquents juvenile' gambling experiences outside of school, which has not been studied thus far. Further, this study has empirical value as its framework includes a joint analysis in terms of welfare and gambling addiction and focuses on a precarious population-delinquent juveniles who have dropped out of school. The results provide a foundation from which practical implications and policy alternatives for the prevention and treatment of gambling problems in delinquent juveniles dropped out of school.

The purpose of this study is to identify the influence of problem gambling on suicidal ideation and suicidal attempts of school adolescents and out-of-school adolescents. Data were obtained from the 2018 Survey on Youth Gambling Problems and analyzed using logistic regressions. The results of this study were as follows: First, Out-of-school adolescents have more problems with the problem gambling severity, experience a decline in academic performance due to gambling, experience of borrowing money from acquaintances of lenders, suicidal ideation and suicidal attempts than school adolescents. Second, regardless of whether they attended school, experience of borrowing money from lenders was identified as significant variable of suicidal ideation and attempt. Third, problem gambling severity, experience of borrowing money from acquaintances of lenders and a decline in academic performance appeared to influence suicidal ideation and suicidal attempts of school adolescents. Based on this results, we suggested the method to decrease suicide due to problem gambling.

This study examined the mediating effects of life satisfaction on the relationship between parent attachment, peer attachment, and depression among Korean out-of-school youths. The study participants of 145 out-of-school youths derived from 5th Panel Survey of School Dropouts. To analyze the collected data, descriptive statistics, Pearson's correlation, and path analysis conducted by using SPSS 26.0 and AMOS 26.0. Parent attachment directly related to life satisfaction. Peer attachment directly related to life satisfaction and to depression. Life satisfaction had a significant negative relationship to depression. Parent attachment (𝛽=-.23, p=.006, 95% CI: -0.33~-0.12) and peer attachment (𝛽=-.18, p=.002, 95% CI: -0.31~-0.08) had indirect effects on depression through mediating life satisfaction. Results of this study indicate that we will discuss implications for possible policies and programs to help out-of-school youth successfully integrate a satisfying life and safely improve depression.

The effective utilization of an airport is considerably influenced by natural features and man-made structures inside and outside its boundary. These obstacles affect the airspace available for approaches and departures and the weather minima which dictates the necessary weather conditions for aircraft to be allowed to take-off or land. Certain areas of the airspace near airports must be regarded as the integral parts of the airport system. The availability of the required airspace is as important as are the runway and their associated strips to the safe and efficient use of the airport. For these reasons, ICAO and the member states have established the standards regarding the obstacle limitation surfaces and regulated the construction of the man-made structures in and beyond the surfaces. Existing objects that extend above a obstacle limitation surfaces should as for as practicable be removed except when, in the opinion of the appropriate authority, an objects is shielded an existing immovable objects, or after aeronautical study it is determined that the object would not adversely affect the safety or significantly affect the regularity of operations of airplanes. However, Korea's aviation law does not specified the outer horizontal surface in the obstacle limitation surfaces, while ICAO and most member states do. The absence of the outer horizontal surface regulation has created legal disputes between regulating agencies and private parties. The case study in this paper found that a skyscraper planned beyond Korea's obstacle limitation surfaces does affect the flight safety and the efficient use of an airport. Therefore, in areas beyond the obstacle limitation surfaces. those objects which extend to a height of 150m or more above ground elevation should be regarded as obstacle, unless a special aeronautical study indicates that they do not constitute a hazard to airplanes. We proposed low alternative regulatory schemes for resolving the issues raised in this paper, and we recommended to adopt ICAO's standards and recommended practices.

Recently, the number of out-of-school adolescents has been increasing, and problems associated with their careers have become an important issue. This study was conducted to identify the relationship between the career barriers and perceived social support type/support source and to examine whether a sense of alienation mediates the relationship between perceived social support and career barriers among out-of-school adolescents preparing for the qualification examination for their high school degree. To accomplish this, a survey of 207 students from the Youth Support Center for out-of-school adolescents-K-Dream-and Qualification Examination Institute located in five regions (Seoul, Busan, Jeju, Gangwon, and Jeonla province) was conducted. Correlation analysis, regression analysis and the Sobel test were used to verify the relationships between variables and mediation effects. The results showed a significant negative correlation between social support and career barriers and a significant positive correlation between alienation and career barriers. Carrier barriers and alienation were highly correlated with parent support and evaluation support. Moreover, a sense of alienation was found to fully mediate the relationship between parental support/teacher support and career barriers, as well as to partially mediate the relationship between peer support and career barriers. A sense of alienation was found to fully mediate the relationship between information support/evaluation support/emotional support/material support and career barriers. These findings imply that, in out-of-school adolescents, career barriers can be reduced through various kinds of social support provided by peers, parents and teachers as it decreases the sense of alienation.

Health inequality means health gaps that can be affected adverse effects to the vulnerable groups in a society. Many scholars argue that it is needed social interventions to reduce health gaps between the vulnerable and the privileged in a society, because social inequalities can be caused and resulted health inequality among them. In this context, this article introduces Korean out of school children health check-up as part of the policies to reduce health inequality in the society. For a long time, many out of school children have been alienated from the national health checkup systems. That means they are not only marginalized groups in Korean society, but also excluded from the benefits of health promotion and health management. Many runaway youths are struggling to live by themselves, who are escaped from their families and they don't have enough resources to keep their health. They are also young and low waged workers who are expelled to the streets, while they don't have any support and protection from the communities. Out of school children health checkup has been conducted to the adolescents who stay in the shelters or study in alternative schools. To get meaningful results as the health inequality reduction policy, it is needed to expand out of children health checkup to the runaway teenagers.

우리나라는 원전연료로 사용되는 우라늄의 부존량이 매우 적을 뿐 아니라 품위가 낮아 경제성이 없으므로 정광을 외국에서 도입할 수 밖에 없으며, 원전연료 제조과정중 가장 중요한 단계인 농축 또한 핵무기 비확산에 관한 조약 등 국내외의 정치적 여건상 기술자립에 제약을 받고 있어 외국에 의존할 수 밖에 없는 실정이다. 이에 따라, 정부는 국내 기술자립에 제약을 받지 않는 성형가공 부문의 국산화를 추진하는 한편 해외의 우라늄광산 개발참여 등을 통해 원전연료의 안정적 확보에 힘쓰고 있다. 정부는 '79년 9월 원전연료 국산화 사업추진을 결정하였으며, '80년 12월에는 세부추진계획을 확정하였는데 그 기본방침은 다음과 같다. 첫째, 경수로연료는 외국과의 합작투자 방식으로 국산화하며, 둘째, 중수로 연료는 자체기술개발에 의해 국산화를 추진한다는 것이다.
