본 연구는 노인부양에 관한 부부간 의사결정 과정에서 부양의 주체인 여성 배우자의 의사결정 파워가 실제 노인부양참여를 위한 결정에 어떤 역할을 하고 있는지 알아보기 위하여 미국내 중고령층을 대상으로 한 2002년 HRS(Health and Retirement Study) 자료를 사용하여 실증분석하였다. 또한 이 연구에서는 배우자 양쪽의 부모로부터 동시에 부양의 역할이 요구되었을 때 부부간 교섭력(Bargaining Power)을 대표할 수 있는 여성의 경제력과 교육수준이 부양결정에 어떤 영향을 미치는지를 다항 로짓 분석 (Multinomial Logit) 분석을 사용하여 검증하였다. 분석결과는 부부의 노부모 부양결정은 부부간 교섭력 보다는 양쪽 부모의 상대적 건강상태, 재정상태, 그리고 간호를 위한 대체 인적자원의 여부등에 의존하는 것으로 밝혀졌다. 또한 남성과는 다르게, 여성의 연령과 노동참여는 여성 자신의 노부모 부양결정에 결코 부적 영향을 주지 않았으며, 또한 양쪽 부모로 부터 동시에 부양참여가 요구되었을때 성인자녀가족의 부양결정은 같은 조건이라면 여성배우자쪽 부모의 부양에 보다 더 적극적으로 반응하는 것으로 밝혀졌다.

The electric power industry has played an important role in dramatic economic development in Korea and the electricity has constituted a critical factor sustaining the well-being of the Korean people. This study uses input-output analysis to investigate the role of four electric power sectors (hydroelectric, fossil-fuels, nuclear and non-utility) in the Korean national economy for the period 1985~1998, focusing on four topics: the impacts of electricity supply investments, the electricity supply shortage effects, and the impacts of the rise in electricity rates, and the inter-industry linkage effect. The overall results reveal that non-utility electric sector is superior in terms of the national economy-wide effects to other three sectors throughout the period. Finally, potential uses of the results are illustrated from the perspective of policy instruments and some policy implications are discussed.

The purpose of this research was to investigate the relations between resources and conjugal power in Korea, with the specific purpose of testing Rodman's theory that norms and resources operate in a cultural context. The subjects of this study were 268 couples with children who lived in nuclear families and resided in Seoul. Relative conjugal power, norms about role and socioeconomic resources of spouses were measured with questionnaires based on Burr's research. The data were collected from one spouse of each couple. The data were analyzed using the Pearson's Correlation and one-way ANOVA. Results of this study generally supported Rodman's theory but were not consistent with Rodman's speculation that resources are more strongly related to power when norms are more equalitarian than patriarchal.

원자력 발전소 운전원에게 발전소 상태를 정확히 알려주는 완벽한 신호가 원자력 발전소 전체의 가용도와 경제성에 얼마만한 영향을 주는가에 대한 정량적인 분석이 이 논문에서 수행되어졌다. 이 분석을 위한 기본 모델들이 개발되어졌고 이 모델들은 발전소가 정상상태에서 비정상상태로 바뀌어갈때 운전원이 발전소가 완전히 비정상상태로 가기전에 발전소를 정상상태로 회복시키는 것에 완벽한 발전소 신호가 얼마만큼 영향을 주는가를 정량화 하였다. 또한 이러한 완벽한 신호가 경제적으로 얼마만큼의 이득을 주는가도 정량화 하였다. 이 모델 적용의 대상으로는 응축 및 주급수 시스템을 선정하였다.

This paper proposes a method for real-time control of both capacitors and ULTC in a distribution system to reduce the total power loss and to improve the voltage profile over the course of a day. The multi-stage consists of the off-line stage to determine dispatch schedule based on a load forecast and the on-line stage generates the time and control sequences at each sampling time. It is then determined whether one of the control actions in the control sequence is performed at the present sampling time. The proposed method is presented for a typical radial distribution system with a single ULTC and capacitors.

The economic development of most countries in the world has negatively impacted fossil energy resources. Fossil energy sources such as petroleum and coal are increasingly depleted. When energy sources are exhausted, renewable energy sources are growing strongly. Renewable energy development can help to replace diminishing fossil fuels. Furthermore, the usage of renewable energy can contribute to a green economy and sustainable development by protecting the environment. Solar power on the roof is one of the many renewable energy sources available. But at present, the investment in roof voltage systems has not developed strongly in Vietnam. This paper uses the SEM model to evaluate the factors affecting investment in rooftop solar power in some provinces of Vietnam. The article uses the household interview method. The article has given 8 factors affecting the decision to invest in rooftop solar power for households. Research results show that most of the factor variables have a positive impact on the decision to invest in rooftop solar power. Based on assessing the factors affecting the decision to invest in rooftop solar power, the article will provide conclusions and policy suggestions to increase investment in rooftop solar power in Vietnam.

Home economics lesson plan model was developed based on cooperative learning stategy focusing on human development and family relations area. The cooperative learning is an instructional strategy that meets the challenge of helping students master home economics content objectives by acquiring and practicing the social skills that are essential in life for satisfactory relationships with peers, families, coworkers, and others in society. Through cooperative learning, students can satisfy their needs for friendship, power, belongs, and fun. Practical problems were selected in human development and family relations area for middle school students assuming that home economics is critical science. Lesson plans were developed according to the practical problems, "what should we do regarding the effective communication between family members\ulcorner".ner".uot;.
