This study was conducted to review the feasibility of establishing a joint preservation library centered on the Chungcheongbuk-do Office of Education. To achieve this, a survey and perception survey were conducted. The research results suggest the following: Firstly, the functions of the Chungcheongbuk-do Office of Education joint preservation library should focus on the preservation of valuable materials, the development of Chungcheongbuk-do educational and school-specialized materials, and prioritizing the digitalization of important transferred materials and providing services to the general public. Secondly, when determining the criteria for materials to be transferred in the future, priority should be given to materials that require preservation in their original form and those that need media conversion. Thirdly, when considering the types of materials to be transferred in the future, the operational plan should primarily focus on monographs but also consider other types of materials. Fourthly, regarding ownership rights of materials during the transfer process, it is advisable to establish detailed transfer guidelines, including ownership rights, through discussions between the Chungcheongbuk-do Office of Education and individual libraries via the Joint Preservation Library Operating Committee.

The purpose of this study is to identify determinants for preferred funeral methods depending on socio-economic characteristics. In South Korea, the Act on Funeral Services, Etc. categorizes funeral methods into burial, inurnment, and natural burial. This study empirically analyzes how and what socio-economic characteristics affect choices among these three categories. Data is collected from Social Survey 2017 and funeral facilities in the country. The data to be analyzed is developed in terms of a hierarchy which puts the burial and cremation methods in an upper class and the inurnment and natural burial methods in a lower class. Based on this data, a nested logit model is employed to conduct empirical analysis. The analysis indicates that those characteristics that have a statistically significant influence on preferred methods include gender, age, householder, marriage, satisfaction with life, class awareness, monthly income, housing type, housing tenure type, and living in city area. Each variable's modulus of calculated direct and cross elasticity need to be used to analyze the outcome of a nested logit model. In this study, the modulus of direct and cross elasticity are determined for the significant variables. The calculated direct elasticity is applied to analyze the likelihood of choosing each funeral method when there are changes in the significant variables. When a particular method has been selected, on the other hand, the cross elasticity is utilized to analyze changes to the likelihood of choosing the other methods. One of the most notable results is related to natural burial. In order to meet the demand for natural burial, it is necessary to provide more burial sites and raise awareness of natural burial. This will facilitate the efficient use of national territorial space.

Twenty years have passed since the adoption of natural recreation forests and each forest has its own characteristics. However, there is hardly any classification among the natural recreation forests. The purpose of this study is to classify the forests by considering the supplier's perspective as well as the user's perspective in order to provide fundamental materials for the operation of the natural recreation forests. A factor analysis was conducted to identify the common characteristics of the selected twelve variables by pre-selection and survey of experts. K-means cluster analysis was conducted among those factors to classify the natural recreation forests in Korea. Four factors were drawn after the factor analysis and the factors were named according to the variables and sizes as 'The use performance and visiting condition factor', 'Education and settlement factor', 'Internal activation factor' and 'Potential factor' In addition, the cluster analysis of an $85{\times}4$ matrix was conducted for the points of the drawn factors and the final classification consists of five groups. The results of this study may contribute to providing fundamental materials for the operation and management of natural recreation forests. Also, it may act as a reference when investigating the natural recreation forests of Korea. Proposing the classification natural recreation forests could be helpful in selecting the proper recreation forest in the future. Based on the established model, fundamental materials could be provided to improve the profitability of the natural recreation forests by effectively expanding the number of tourists, creating new natural recreation forests and proper maintenance and management.

Inquiry became an essential methodology in science education. Recently, argumentation becomes more important in inquiry, but inquiry-based teaching in school science would not provide enough opportunities for students to have voluntary and active interactions during inquiry activities. Informal science learning can be an alternative for authentic inquiry. Accordingly, this study aims to find interaction patterns in dialogic inquiry of junior high school students in small groups in the natural history gallery. Inquiry elements and interaction patterns are analyzed with 42 dialogues of 13 small groups. As a result, seven interaction patterns are identified. First, five major interaction patterns were drawn as follows; Sharing questions, asking questions and simple response, asking questions and simple explanation, asking questions-simple explanation-(collecting data)-data based explanation, and asking questions-collecting data-data based explanation. Second, pattern 2, 'asking questions and simple response', is subdivided into three categories; passive and/or evasive response, inaccurate response, and repeated patterns of asking questions-simple response. The results of the study provide different patterns of dialogic interactions in a small group inquiry in informal contexts from formal contexts, and provide foundations to understand middle school students' interactive dialogues of inquiry occurred in the natural history gallery.

This study is objected to demonstrate the spatial variability of the ground-water recharge by classifying the types of ground-water hydrographs and assessing the recharge ratio(the ratio of the rise of ground-water level to cumulative precipitation) of each type using the National Ground-water Monitoring network data. A total of 5 types were identified by factor analysis on the ground-water hydrographs nationwide. The recharge ratio of each type were estimated to be 6.5% (TYPE I), 4.1 % (TYPE II), 9.2%(TYPE III), 5.8 %(TYPE IV), 15.3 %(TYPE V) in the confidence level of 95.44% and 6% variation was estimated site by site even in the same type. The recharges of Han, Nakdong, Keum, Youngsan·Seomjin river basins were estimated as 10.0 %, 6.1 %, 8.3 %. and 6.6 % respectively. These results were consistent with the results of the existing baseflow method.

This study examined the acculturation strategies of immigrant women and the relationship in adolescents' career development. The data were from 2016 Multicultural Adolescents Panel Study, 1,248 cases. The highest rate was the assimilation followed by integration, separation and marginalization among immigrant women' acculturation strategies. The parenting efficacy, behaviors for career development and parents' support were related with acculturation strategies. The adolescents' career attitudes and perceived career barriers were also related with the acculturation strategies of immigrant mothers. As compared other strategies, assimilation strategy had positive relationships with parenting efficacy, behaviors for career development, parents' support, adolescents' career attitudes and perceived career barriers. This study provided some implications for immigrant families with adolescents.

본 연구에서는 1980년부터 2008년까지의 재해역학조사센터(http://www.emdat.be/)의 자료를 활용하여, 북한지역의 홍수로 인한 피해를 조사하였다. 북한의 홍수 발생 기간 중 약 70%가 주로 7월과 8월에 발생하였으며, 홍수로 인한 총 재산피해는 약 180억 달러에 달한다. 이중 1995년의 홍수는 약 150억 달러로 세계 50대 자연재해로 기록되었다. 또한, 2007년의 홍수는 북한의 자연재해 중 가장 많은 인명피해로 당시 사망자는 600명 이상이 기록되었다. 북한의 홍수 유형별 피해 규모를 분석하기 위하여 홍수 유형을 불특정 홍수, 돌발 홍수, 일반 홍수로 분류하여 분석하였다. 또한, 남북한의 차이를 분석하기 위하여 남한의 홍수 사례를 같은 유형으로 분류하여 함께 비교하였다. 유형별 빈도는 남한의 경우 3가지 유형이 비슷한 빈도로 발생된 반면, 북한의 경우 일반홍수의 빈도가 다른 홍수의 빈도 보다 조금 많이 발생하였다. 유형별 인명피해 부분에서는 남한은 전체 유형에서 돌발홍수가 52%로 가장 많은 부분을 차지했으며, 북한의 경우는 일반홍수가 42%로 가장 많이 차지하였다. 결론적으로 남한은 일반홍수와 돌발홍수의 빈도는 같았으나, 돌발홍수가 인명피해 면에서 2.3배 많이 발생하였으며, 북한의 경우 불특정 홍수와 돌발홍수의 발생 빈도는 같았으나, 돌발홍수로 인한 인명피해가 1.5배 많이 발생하였다. 경제적 피해 부분에서는 남한의 경우 돌발홍수가 약 19억 달러로 가장 많은 피해액을 발생시켰으며, 북한의 경우 일반홍수가 약 153억 달러로 가장 많은 피해액을 발생시켰다. 이는 남한의 약 7배에 해당하는 금액이다. 남북한이 경제적 피해 부분에서 큰 차이를 보이는 것은 1995년의 대홍수의 피해액이 약150억 달러로 기록되었기 때문으로 사료된다. 향후 기후변화로 인하여, 자연재해는 더욱 증가할 것으로 생각된다. 남한의 연구뿐만 아니라 한반도 전체에 대한 연구가 필요하다. 현재, 북한의 경우 기상 현상, 재해정보 등의 연구 자료는 남한 지역의 연구에 비해 상대적으로 많이 부족하며, 매우 제한적이고 단편적인 자료들만 존재하고 있다. 따라서 이에 관한 많은 연구들이 필요한 실정이다. 현재 작성되어 있는 북한의 재해 취약성 지도를 좀 더 연구하여, 한반도 전체의 재해 취약성 지도의 작성이 필요할 것으로 생각된다. 또한, 한반도 지역에서 발생하는 위험기상에 따른 사회경제적 피해를 줄이고 능동적으로 대처하기 위해 남북간 기상협력이 활성화 될 필요가 있을 것으로 생각된다.
