This study is the case of non-face-to-face teaching-learning in the subject of "Research and Guidance on Early Childhood Materials" in the pre-child teacher training program. The study conducted a non-face-to-face teaching-learning model for 18 students at B University in region C who took lectures on 'Research and Guidance on Early Childhood Materials' in the first semester of 2021. As a non-face-to-face teaching-learning model, it consisted of video lectures, real-time zoom classes, and various forms of 'communication' through frequent feedback and interaction and 'participation'. As a teaching-learning strategy for the participation of pre-service early childhood teachers, comment on questions related to early childhood materials, in-depth reflection on early childhood materials through writing reflective journals and observation reports, and step-by-step presentation of making childhood materials plans, processes, and results were carried out. As a result of exploring the experience of making early childhood materials for pre-service early childhood teachers, factors such as "growth experience through trial and error," "thinking from child's point of view", "Increase efficiency and reduce burden through communication", "Process rather than result" and "The importance of communication and interaction in non-face-to-face classes"

In this study, we revealed the location environment and community structural characteristics after extensively investigating Korea's warm-temperate island areas and categorizing vegetation through TWINSPAN analysis. Based on it, this study aims to suggest the direction of the vegetation restoration plan for warm-temperate forests by deriving a restoration strategy for each vegetation type. The vegetation types were clearly divided into eight types, and communities I through IV were good evergreen broad-leaved forests dominated by Machilus thunbergii and Castanopsis sieboldii. On the other hand, communities V through VIII were Pinus thunbergii forest, deciduous broad-leaved forest, and artificial forest, and retrogressive succession vegetation in the warm-temperate areas. The environmental factors derived from the DCA analysis were altitude (average temperature of the coldest month) and distance from the coastline (salt tolerance). The distribution pattern of warm-temperate forests has been categorized into M. thunbergii, C. sieboldii and Cyclobalanopsis spp. forest types according to the two environmental factors. It is reasonable to apply the three vegetation types as restoration target vegetation considering the location environment of the restoration target site. In communities V through VIII, P. thunbergiiand deciduous broad-leaved formed a canopy layer, and evergreen broad-leaved species with strong seed expansion frequently appeared in the ground layer, raising the possibility of vegetation succession as evergreen broad-leaved forests. The devastated land where forests have disappeared in the island areas is narrow, but vegetation such as P. thunbergii and deciduous broad-leaved forests, which have become a retrogressive succession, forms a large area. The restoration strategy of renewing this area into evergreen, broad-leaved forests should be more effective in realizing carbon neutrality and promoting biodiversity.

The purpose of this study is to investigate beginner and experienced Korean science teachers' perceptions about the science teacher preparation courses from which they graduated, and to compare them. The study was conducted as a qualitative study using in-depth interviews. For the study, interview questions were developed by the authors based on the questionnaire of 'The IMPPACT project' that was being conducted in America. The interview tool includes questions about their experience of science subject matter content knowledge, science pedagogical content knowledge, and general pedagogical content knowledge in their preparation courses. For the interview, seven beginning science teachers, less than five years of teaching experience, and five experienced science teachers, more than five years of teaching experience, were sampled from secondary schools in Korea. The research results are as follows: First, most of the beginner and experienced science teachers perceived that the teaching methods in the classes of science subject matter were not good model for teaching science in their secondary school, because they were not diverse enough and entailed mostly knowledge transfer just through lecture without teacher-student interaction. Second, most of the beginner science teachers perceived that they were affected positively by the teaching strategies and evaluation methods in the classes for science pedagogical subject matter and they could apply those strategies and methods in their current science teaching. Lastly, most of the beginner and experienced science teachers perceived that general pedagogical subject matter is important and prerequisite for science teaching in their schools, but the courses that they experienced at their university were not appropriate for their current teaching.

The interests in alternative office systems and solutions (called smart work in Korea) are growing. With the lens of boundary theory, this paper tries to understand the nature of work/nonwork boundaries which smart work will be expected to blur. Boundary theory provides permeability, boundary strength, and interference as its key concepts and an empirical study is performed about the individual perception on those concepts. The result of the survey from telecommuters and/or smart work center users at the Company K shows that they perceive work/nonwork permeability, boundary strength, and interference are asymmetric. The result suggests that asymmetric nature of the work/nonwork boundaries should be taken into account when alternative office systems are brought into use.

일반적으로 감조하천의 홍수위는 홍수량과 조위에 의해 결정된다. 그러나 하류에 하구둑이 있는 경우, 홍수위는 하구둑의 운영에 더 많은 영향을 받게 된다. 이러한 감조하천구간의 설계홍수위를 산정할 때는 하구둑의 운영과 조위 조건을 모두 고려해야한다. 본 연구에서는 하구둑의 운영을 모의할 수 있는 부정류 계산모형을 개발하고 이를 낙동강에 적용하여 하구둑과 창녕함안보 구간에 대해 100년 빈도 계획홍수위를 산정하였다. 하구둑의 수문 운영 전략은 하구둑 직상류 수위가 외조위보다 낮거나 같을 경우 수문이 폐쇄되도록, 그 외의 경우에는 수위가 상승할수록 개도를 증가시키도록 수립되었다. 조위 시나리오로 가상조위를 부산 검조수위표의 4대 분조 조화분석 자료를 활용하여 생성하였다. 대조기와 소조기를 포함한 다양한 조위 조건과 매개변수를 달리한 여러 운영방안에 대해 100년 빈도 홍수사상을 모의하였다. 수문 운영 방안에 포함된 매개변수들과 조위 조건에 대한 민감도 분석을 수행하여 매개변수들의 변화에 따른 계산결과들의 분석을 수행하고 모의 계산된 홍수위들로부터 100년 빈도 계획홍수위를 산정하였다.

본 연구에서는 실시간 통합 물관리 시스템의 일환으로 월별 일강수량 예측 시스템에 관한 연구를 실시하였다. 선행시간 2일 예측에 대해서는 기상청 생성 수치모의 RDAPS (Regional Data Assimilation and Prediction System)를 기반으로 강수진단모형인 QPM (Quantitative Precipitatiom Model)을 이용하여 지형효과를 보정하였으며, 선행시간 2일에서 8일까지의 예측에 대해서는 GDAPS (Global Data Assimilation and Prediction System) 모의결과를 QPM을 이용하여 보정하였고, 선행시간 10일 이후의 예측값은 통계적 기법을 이용한 자료를 활용하였다. 통계적 기법으로는 과거 20년간의 관측된 강수경향을 이용하여 시스템을 구축하였다. 강수진단모형 (QPM)은 Misumi et al. (2001), Bell (1978), Collier (1975)등이 제안한 바 있는 Collier-type의 모형으로서 이들 모형은 소규모 지형 효과를 고려한 강수량을 산출하는 진단 모형이다. QPM은 중규모 예측 모형으로부터 계산된 수평 바람, 고도, 기온, 강우 강도, 그리고 상대습도 등의 예측 자료를 이용하고, 중규모 예측 모형에서는 잘 표현되지 않는 소규모 지형 효과를 고려함으로써 중규모 예측 모형에서 생산된 상대적으로 성긴 격자의 강수량 예측 값을 상세 지역의 지형을 고려한 강수량 예측 값으로 재구성하게 된다. QPM은 중규모 모형으로부터 나온 자료를 초기 자료로 이용하고 3 km 간격의 상세 지형을 반영하는 모형으로 소규모 지형 효과를 표현함으로써 상세 지역에서의 강수량 산출과 지형에 따른 강수량의 분포 파악이 용이할 뿐 아니라, 계산 효율성을 개선시킬 수 있다.착능이 높은 것으로 사료되었다.X>${\mu}_{max,A}$는 최대암모니아 섭취률을 이용하여 구한 결과 $0.65d^{-1}$로 나타났다.EX>$60%{\sim}87%$가 수심 10m 이내에 분포하였고, 녹조강과 남조강이 우점하는 하절기에는 5m 이내에 주로 분포하였다. 취수탑 지점의 수심이 연중 $25{\sim}35m$를 유지하는 H호의 경우 간헐식 폭기장치를 가동하는 기간은 물론 그 외 기간에도 취수구의 심도를 표층 10m 이하로 유지 할 경우 전체 조류 유입량을 60% 이상 저감할 수 있을 것으로 조사되었다.심볼 및 색채 디자인 등의 작업이 수반되어야 하며, 이들을 고려한 인터넷용 GIS기본도를 신규 제작한다. 상습침수지구와 관련된 각종 GIS데이타와 각 기관이 보유하고 있는 공공정보 가운데 공간정보와 연계되어야 하는 자료를 인터넷 GIS를 이용하여 효율적으로 관리하기 위해서는 단계별 구축전략이 필요하다. 따라서 본 논문에서는 인터넷 GIS를 이용하여 상습침수구역관련 정보를 검색, 처리 및 분석할 수 있는 상습침수 구역 종합정보화 시스템을 구축토록 하였다.N, 항목에서 보 상류가 높게 나타났으나, 철거되지 않은 검전보나 안양대교보에 비해 그 차이가 크지 않은 것으로 나타났다.의 기상변화가 자발성 기흉 발생에 영향을 미친다고 추론할 수 있었다. 향후 본 연구에서 추론된 기상변화와 기흉 발생과의 인과관계를 확인하고 좀 더 구체화하기 위한 연구가 필요할 것이다.게 이루어질 수 있을 것으로 기대된다.는 초과수익률이 상승하지만, 이후로는 감소하므로, 반전거래전략을 활용하는 경우 주식투자기간은 24개월이하의 중단기가 적합함을 발견하였다. 이상의 행태적 측면과 투자성과측면의 실증결과를 통하여 한국주

This study aims to set up the appropriate strategies for the transboundary river between South and North Korea. We took the example of Bukhan River which penetrates both Koreas to illustrate this idea, and applied Game Theory to get the solutions. Previous studies have mainly dealt with counterplan in case of confliction. On the contrary, this study has the premise that there could be much more cooperations. The analysis shows that the best choice is to develop the basin together. For example, they can make up development plan for Imjin basin which ranges from North Korea and South. As the result, South Korea can get the stable water volume in the river and North Korea can have the chances for economic revitalization.

This study is a life history on self-realization of woman in the abstinence of alcohol process. The purpose of the study is to explore the circumstance of female alcoholism, to expand the prospect of discussion for treatment and recovery, and to suggest social welfare intervention measures. The study involved a female alcoholic who had been recovering for more than seven years, and the text for life history analysis was divided into 'dimension of life', 'turning point' and 'adaptation' based on the life history analysis framework proposed by Mandelbaum. As a result of the data analysis, 'dimension of life' was analyzed into three areas, such as the personal level of life, the family level of life, and the social dimension. 'Turning point' is to escape from a father who drinks alcohol and uses violence, to give up his job to avoid boss's abuse, and to proceed one's own way of healing. 'Adaptation' was derived into good at studying, relieving anger by drinking alcohol, and referring to AA and self-realization. Based on these findings, this study presented the social welfare practice and policy discussion focused on self-realization.

This paper proposes strategy development to improve the management of Multicultural Family Support Centers by analyzing four Multicultural Family Support Centers (MFSCs) in Chungcheongnam-do. The research was conducted from September 2012 to January 2013. Future directions for the four MFSCs are established based on a SWOT analysis on both the internal and external environments of the centers. Various strategic directions for the four MFSCs were identified based on these analyses. For center A (urban type, college contract type), the strategic directions included the specialization strategy, systemization strategy, empowerment strategy, standardization strategy, and achievement maximization strategy. The strategic directions for center B (urban-rural combined type, social welfare center contract type) included the improvement of multiculture awareness, specialization strategy, human resource development strategy, and networking strategy. For center C (farming and fishing community type, direct management type by local authority), the strategic directions included the specialization strategy, activation strategy, qualification strategy, and networking strategy. For center D (farming and fishing community type, social welfare center contract type), the strategic directions included the specialization strategy, business standardization strategy, human resource development strategy, and network expansion strategy. The suggested management strategy development for the four MFSCs can provide implications for the management of MFSCs in other areas in Korea.
