이 연구의 목적은 우리나라 자립준비청년을 대상으로 한 정책의 현황 과 문제점을 파악하고 개선 방안을 논의하는 것이다. 자립준비청년은 원 가정에서 분리되어 국가의 보호를 받다가 성인이 되어 보호가 종료된 뒤 자립을 준비하고 실행하는 청년들을 말하며, 이들은 경제적, 교육적, 심 리적, 사회적으로 다양한 문제를 겪고 있다. 이들을 지원하기 위해 보건 복지부 중심의 자립지원정책이 2019년부터 본격화되었으나, 지금까지의 연구와 논의들은 자립지원정책을 통합적으로 살펴보지 못한 한계가 있 다. 본 연구는 정책자료와 학술자료를 바탕으로 자립지원정책의 현황과 문제를 종합적으로 분석했다. 분석 결과, 자립지원정책은 부처 간 지원 내용에서 차이가 있었고, 이는 자립준비청년 간 자립역량과 자립수준의 격차로 이어질 가능성을 확인했다. 특히, 현 정책은 청년이 된 이후의 지 원에 초점이 맞추어져 있고 청소년기부터 개인별 자립역량을 체계적으로 강화할 수 있는 로드맵이 부재했다. 이에 본 연구는 자립준비청년 지원 정책의 개선 방안으로, 자립지원 전달체계의 통합과 자립지원 방식의 다 각화를 제안하였다.

To investigate the impact of forestry projects on the carbon stocks of forests, we estimated the carbon stock change of above-ground and soil before and after forestry projects using forest type maps, forestry project information, and soil information. First, we selected six map sheet with large areas and declining age class based on forest type map information. Then, we collected data such as forest type maps, growth coefficients, soil organic matter content, and soil bulk density of the estimated areas to calculate forest carbon storage. As a result, forest carbon stocks decreased by about 34.1~70.0% after forestry projects at all sites. In addition, compared to reference studies, domestic forest soils store less carbon than the above-ground, so it is judged that domestic forest soils have great potential to store more carbon and strategies to increase carbon storage are needed. It was estimated that the amount of carbon stored before forestry projects is about 1.5 times more than after forestry projects. The study estimated that it takes about 27 years for forests to recover to their pre-thinning carbon stocks following forestry projects. Since it takes a long time for forests to recover to their original carbon stocks once their carbon stocks are reduced by physical damage, it is necessary to plan to preserve them as much as possible, especially for highly conservative forests, so that they can maintain their carbon storage function.

In the present work, ZnO nanofibers were applied to electrode materials for the detection of cholesterol. ZnO nanofibers were synthesized using the electrospinning technique with zinc acetate as a precursor. Electrospinning-synthesized ZnO nanofibers were uniformly distributed by properly controlling the electrospinning parameters. After the calcination treatment, nanofibers of pure ZnO phase were synthesized. Then, these fibers were successfully placed on Au-coated glass substrates by dispersion of ZnO nanofibers in ethanol, dropping, and drying, in sequence. Cholesterol oxidase was then immobilized onto the surface of the ZnO nanofibers. To enhance the immobilization, Nafion was additionally applied. The sensing performances of the fabricated ZnO nanofibers-based sensors were analyzed by cyclic voltammetry in terms of cholesterol concentration ranging from 100 to 400 mg/dl. In the I-V curves, measured by cyclic voltammetry, the ZnO nanofiber-based sensor showed a proportional current behavior with cholesterol concentrations in phosphate buffered saline solution. The sensitivity was measured and found to be 30.7nA/mM·cm2, which is comparable to the values reported in the literature. After not only optimizing the shape of the ZnO nanofibers but also improving the adhesion nature between the ZnO nanofibers and the Au conducting layer, these fibers can be a good candidate for electrode materials in devices used to detect low concentrations of cholesterol in blood.

The purpose of this study is to observe the influence mother's pro-environmental consumption behavior have on the adolescents' environment-friendly attitudes and adolescents' pro-environmental consumption behavior. Also by examining the variable relation, the study scopes out the effectiveness of environmental experience. For the analysis, high school students in Korea were gathered from online and multiple regression analysis, and Baron and Kenny mediation analysis were conducted among a total of 521 surveys. The main findings are as follows: First, mother's pro-environmental consumption behavior were proven to be essential factors that have influence on the adolescents’ environment-friendly attitudes. Second, mother's pro-environmental consumption behavior were proven to be essential factors that have influence on the adolescents’ pro-environmental consumption behavior. Third, mediating effect of adolescents' environment-friendly attitudes was verified in the relationship between mother's and adolescent's pro-environmental consumption behavior. The findings suggest the importance of adolescents' environment-friendly attitudes and improve adolescent's pro-environmental consumption behavior by having practice mother's pro-environmental consumption behavior.

The purpose of this study was to observe the influence adolescents’ environmental experience and environmental consciousness have on the pro-environmental consumption behavior. Also by examining the variable relation, the study scoped out the effectiveness of environmental experience. For the analysis, high school students in Korea were gathered from online and the correlation analysis, multiple regression analysis, and Baron and Kenny mediation analysis were conducted among a total of 521 surveys. The main findings are as follows: First, adolescents’ environmental experience, environmental consciousness and pro-environmental consumption behavior showed a positive relationship. In other words, the more the experience, the more sense of responsibility adolescents had towards the environment and society, leading them to have pro-environmental consumption behavior. Second, environmental experience and environmental consciousness were proven to be essential factors that have influence on the adolescents’ pro-environmental consumption behavior. Third, partial mediating effect of environmental consciousness was verified in accordance with the relationship between environmental experience and pro-environmental consumption behaviour. The findings suggest the importance of adolescents' environmental consciousness and improvement of pro-environmental consumption behavior by having students gain environmental experience.

The purpose of this study is to examine green consumer behavior (green product purchasing behavior and green consumption life) affected by demographical characteristics, and cognition degree of green life (cognition of a green indicator, a green life catalyst system, and environmental problems). It's also to promote strategy and suggest effective activation plans for the vitalization of green consumer behavior. To carry out the task, verification of credibility, multiple regression analysis, two-step cluster analysis, and multinomial logistic analysis were used. The results are as follows: First, the factors that effect green product purchasing behavior were gender, age, cognitive of a green indicator, carbon points system, electricity peak hour system, and seriousness of environmental damage due to lifestyle. Second, the factors that effect green lifestyle were gender, age, carbon grade indicator system, cognition of a green system, and the seriousness of environmental damage due to lifestyle. Third, the comparative group characteristic analysis showed low rates for careless green consumer behavior groups compared to the passive green consumer behavior groups in cognition of a green indicator, green system, and environmental problems. For active green consumer behavior groups, the analysis showed high rates in cognition of carbon grades, eco-labeling, electricity peak hour system, and environmental damage due to lifestyle. In order to encourage green consumer behavior, it's evident that cognition of a green indicator, a green life catalyst system, and environmental problems need to be improved through strategic education and continuous encouragement.
