The purpose of this study was to calculate the economic effect of Women-Farmer's Center. Since 2001, The Ministry of Agriculture and Forestry has run Women-Farmer's Centers in which women-farmers can receive the care for their pre-schooling children, after-school learning service, and city-farm exchange, education, and counseling. In other words, Women Farmer's Center provides not only improvement of ease and quality of life of women-farmer's, but also spreading economic effect to community and country. By calculation based on business plan of 14 centers that run centers, total economic income effects are 2,784 million won, which consist of 1,265 million won for counseling, 146 million won for the care of infants and children, 139 million won after-school learning, 1,020 million won for education, and 214 million won for city-farm exchange program. The Women-Farmer's Center should be managed reasonably with government support so that Women-Farmer's Center will become as a base camp for young women farmers to participate in agriculture and rural community and increase its economic effect for the nation in the future.

The research aims to find implications of machine learning and urban big data as a way to construct the flexible transportation network system of smart city by responding the urban context changes. This research deals with a problem that existing a bus headway model is difficult to respond urban situations in real-time. Therefore, utilizing the urban big data and machine learning prototyping tool in weathers, traffics, and bus statues, this research presents a flexible headway model to predict bus delay and analyze the result. The prototyping model is composed by real-time data of buses. The data is gathered through public data portals and real time Application Program Interface (API) by the government. These data are fundamental resources to organize interval pattern models of bus operations as traffic environment factors (road speeds, station conditions, weathers, and bus information of operating in real-time). The prototyping model is implemented by the machine learning tool (RapidMiner Studio) and conducted several tests for bus delays prediction according to specific circumstances. As a result, possibilities of transportation system are discussed for promoting the urban efficiency and the citizens' convenience by responding to urban conditions.

4차 산업혁명으로 인공지능(AI, Artificial Intelligence) 관련 기술이 고도로 성장함에 따라 여러 분야에서 AI를 접목하는 사례가 증가하고 있다. 주요 원인은 정보통신기술이 발달됨에 따라 기하급수적으로 증가하는 데이터를 사람이 직접 처리·분석하는데 현실적인 한계가 있고, 새로운 기술을 적용하여 휴먼 에러에 대한 리스크도 감소시킬 수 있기 때문이다. 이번 연구에서는 '원격 전위 측정용터미널(T/B, Test Box)'로부터 수신된 데이터와 해당시점의 '원격 정류기' 출력을 수집 후, AI가 학습하도록 하였다. AI의 학습 데이터는 최초 수집된 데이터의 회기분석을 통한 데이터 전처리로 확보하였고, 학습모델은 심층 강화학습(DRL, Deep Reinforce-ment Learning) 알고리즘 중(中) Value기반의 Q-Learning모델이 적용하였다. 데이터 학습이 완료된 AI는 실제 도시가스 공급지역에 투입하여, 수신된 원격T/B 데이터를 기반으로 AI가 적절하게 대응하는지 검증하고, 이를 통해 향후 AI가 전기방식 관리에 적합한 수단으로 활용될 수 있는지 검증하고자 한다.

수요 반응은 전력망의 신뢰성을 높이고 비용을 최소화하기 위해 수요가 가장 많은 시간대에 고객이 소비패턴을 조정하도록 유도한다. 재생 에너지원을 스마트 그리드에 통합하는 것은 간헐적이고 예측할 수 없는 특성으로 인해 상당한 도전 과제를 안고 있다. 강화 학습 기법과 결합된 수요 대응 전략은 이러한 문제를 해결하고 기존 방식에서는 이러한 종류의 복잡한 요구 사항을 충족하지 못하는 경우 그리드 운영을 최적화할 수 있는 접근 방식으로 부상하고 있다. 본 연구는 재생 에너지 통합을 위한 수요 반응에 강화 학습 알고리즘을 적용하는 방법을 찾아 적용하는데 중점을 둔다. 연구의 핵심 목표는 수요 측 유연성을 최적화하고 재생 에너지 활용도를 개선할 뿐 아니라 그리드 안정성을 강화하고자 한다. 연구 결과는 강화 학습을 기반으로 한 수요 반응 전략이 그리드 유연성을 향상시키고 재생 에너지 통합을 촉진하는 데 효과적이라것을 보여준다.

An ideal teaching-learning method, such as the blended learning method, is to motivate interests in education and to allow active class participation of students. Students exposed to this method are hypothesized to be dedicated in learning and their school life. A research was conducted on $11^{th}$ graders in Daejeon city high school specialized in industry; the blended learning method was applied to a course, digital logic circuit and the effects on the students' learning were monitored. The result shows that compared with a common leaning method, the blended learning method is very effective in terms of increasing educational interest, class participation, the level of concentration in class and academic achievement of students. Also, it shows positive feedbacks from the students on the educational videos and the usage of the contents. Conclusively, the blended learning method effectively increases academic achievements through improved educational motivation and active class participation which positively affect the overall satisfaction of participants.

Out-door learning activity in environmental education has been emphasized as an effective method in environmental education since the aims of environmental education emphasize students'value, attitude, actions as well as knowledge. In order to implement successfully out-door learning activity in environmental education classrooms, teachers'perceptions to environmental problems and experiences at fields are essential. An environmental education network among the metropolitan city and provincial office of education, nongovernmental organization of environmental movement and education and university was established and a teachers'in-service training program of out-door learning centered environmental education was implemented. The program was developed in order to 1) connect environmental education with the regional environmental situations, 2) provide teachers with opportunities to participate in an out-door learning program, and 3) train teachers to be environmental education leaders of out-door learning. For evaluation of the program, responses of participants to questionnaire were analyzed. Most of teachers responded that their perception of environment was changed positively after the participation in the program. This study suggested that a future planning of a teachers'in-service training program of out-door learning centered environmental education should be developed in considerations of arranging enough hours for out-door learning at regional environmental sites, applying performance assessment, providing teachers with multiple opportunities with programs in different levels including enriched programs, and establishing an environmental education network among nongovernmental organization of environment movement and education, university, and local offices and department of education.

The purpose of this study was to identify the factors that affect middle-old aged housewives' participation in lifelong learning as a part of human resource development. Through purposive sampling, the study recruited 163 full-time housewives over age 40 years who live in C City. As a result, first, 87.1 percent of all respondents, or 142, said they were willing to participate in lifelong learning in the future. There was no statistically significant difference in the results of cross-checking by age, educational background and monthly household income variables. Additionally, we used cluster analysis to measure differences in participation intentions according to the perception of human resource development of middle-old aged full-time housewives. The perception variable of lifelong learning is: First, Cognitive degree, second, importance, third, activation awareness. Cluster 1(n=16) was divided into generally low-perception types, such as cognitive degree, importance, and life-long learning activation of the C city, while Cluster 2(n=61) was classified as a type of person who thinks that lifelong learning is important to life and Cluster 3(n=86) was generally classified as a type with a higher lifelong learning perception. and we found that there was no difference in the intention to participate in lifelong learning by all cluster Lastly, we found that participants who valued human resource development scored significantly higher on measures of cognition than those who did not value it. Based on these results, we advocates social change that encourages the cultivation of talent through lifelong learning programs that can positively affect one's unique identity, not just wife and mother, and provide opportunities for self-development.

본 연구에서는 초등수학영재와 일반학생의 의사소통 능력과 자기주도적 학습능력의 차이를 비교 분석하여 영재의 특성에 대해 폭넓게 이해하고 더 나아가 의사소통 능력과 자기주도적 학습능력의 상관관계를 알아보고자 한다. 이를 위해 D광역시 소재 영재교육원, 영재학급의 초등수학영재 126명과 일반학생 124명을 연구대상으로 선정하여 의사소통 및 자기주도적 학습능력에 대한 지필검사를 실시하고 그 결과를 분석하였다. 연구 결과 초등수학영재와 일반학생들 간의 의사소통 능력과 자기주도적 학습능력에는 유의미한 차이를 보였으며 초등수학영재가 일반학생보다 높은 것으로 나타났다. 또한 각 집단별 의사소통 능력과 자기주도적 학습능력의 관계에서도 두 집단 모두 정적인 상관관계를 보였으며 초등수학영재가 보다 높은 정적상관관계를 나타내었다. 따라서 수학영재 프로그램의 개발뿐만 아니라 교수 학습에 있어서 의사소통 능력과 자기주도적 학습능력간의 상호관련성을 충분히 고려하여 지도하는 것이 필요하다.
