본 연구는 유아기 자녀에 대한 어머니의 애착과 기대가 유아교육기관 교육환경 요구에 미치는 각 하위요인을 찾고 이들 변인 간 구조관계를 분석하여 유아교육기관에 대한 사회적 요구의 근본적인 동기를 파악하는 것이다. 연구대상은 3〜5세의 자녀를 유아교육기관에 취원시키고 있는 전국의 408명의 어머니이다. 자료수집은 2017년 6월 13~16일 동안 실시하고 설문자료의 분석은 SPSS 22.0과 AMOS 20.0을 사용하였다. 연구결과를 바탕으로 유아기 자녀에 대한 어머니의 애착과 기대가 유아교육기관 교육환경에 미치는 구조관계는 첫째, 유아기 자녀에 대한 어머니의 애착과 기대, 교육기관 요구는 유아의 연령과 성별에 따라 차이가 나타나므로 유아교육기관은 유아의 연령과 성별에 따라 적절한 교육환경 구성에 관심을 가져야 한다. 둘째, 유아기 자녀에 대한 어머니의 기대는 어머니의 애착과 교육기관 요구를 부분매개 한다. 자녀에 대한 애착이 기대로 기대가 우수한 유아교육기관 교육환경을 요구하는 관계도를 형성한다는 것을 알 수 있다. 따라서 유아교육기관은 유아의 발달을 고려한 교육환경구축과 함께 유아에 대한 애착을 바탕으로 이들을 충분하게 보호하고 안심할 수 있는 환경 구성에 관심을 가져야 할 것이다. This study is to find each sub-factor of the mother s attachment and expectation to the infant education institution s educational environment needs, analyze these transformative human structural relationships, and identify the fundamental motivation of the social needs of the infant education institution. The study selected 420 mothers across the country who are applying for children aged 3 to 5 years old to preschool education institutes. Data collection was conducted for 13 to 16 days of June 2017 and the analysis of the survey data was made using SPSS 22.0 and AMOS 20.0. Based on the results of the study, the structural relationship between the attachment and expectation of the mother to the educational environment of the infant education institution, firstly, the mother s attachment and expectation to the infant s child, and the demands of the institution vary depending on the age and sex of the infant, so the infant education institution should pay attention to the composition of the appropriate educational environment according to the age and gender of the infant. Second, the mother s expectations of her infant child partly reflect the mother s attachment and the educational institution s demands. You can see that attachment to children forms a elationship that calls for an educational environment for children with high expectations. Therefore, child education institutions should pay attention to the establishment of an educational environment that takes into account the development of infants and, based on their attachment to infants, fully protects them and provides a safe environment.

In this study, we assessed dependency of small hydropower potentials on the two different runoff such as the estimated runoff based on the rainfall amounts and measured runoff. The hydpropower potentials were evaluated using actural power generations taken from Deoksong, Hanseok, and Socheon small hydropower plants over Han and Nakdong river basins, respectively. As a result of comparing the actual power generation amount with the potential amount based on the rainfall amount and the estimated amount based on the observed flow amount by each small hydroelectric power plant, the degree of latent small hydro energy by the observed flow was confirmed to be high. It is confirmed that the potential hydroelectric power generation rate is estimated to be about average 30%Point higher than the actual generation amount as a result of the measured flow rate rather than using the rainfall amount. Based on this, a method for improving the degree of the actual generation amount is proposed.

본 연구는 태양에너지로부터 전기와 온수를 생산하고, 여름철에 얻어진 열을 개간 축열조인 BTES 저장하여 겨울철 지열원 히트펌프인 GSHP의 열원으로 사용하는 복합 시스템이다. 열을 생산 및 저장 그리고 소비하는 복합시스템에서의 최적운전을 위한 제어변수 추출과 유기적인 제어를 위한 전략 수립은 필수적이다. 본 연구에선 최적 운전 전략 수립을 위하여 제어변수 추출과 전략 수립 방법을 기술하고 있다. PVT, GSHP, BTES가 연동된 최적운전수립은 각 시스템의 데이터를 장기간 수집하고 종합적인 분석을 통해 시스템 사이의 상관관계를 파악하는 것이 반드시 필요하다. 본 연구는 PVT, GSHP, BTES의 데이터를 수집하기 위한 시스템 구성과 데이터 활용 방안에 대하여 연구를 수행하였다.

This study was to understand the component that affects the formative beauty and to present the direction of bridge design for improving the image of urban landscape to survey the visual effect and landscape Preference by the change of bridge type. The results of this study are as follows. In the results of image analysis by bridge types, the images of one-arch bridges are unique and interesting, whereas more than two successive arched bridge were harmonize, stable, consecutive and regular. In the case of the arch rib, braced-rib arch bridge was assessed that complicated, diverse and interesting more than solid-rib arch bridge. The results of factor analysis on the psychological factor were classified into three categories: orderliness, aesthetic and symbolism. In the results of analysis on psychological factors by bridge types, the orderliness and symbolism were different in the position of path, and the number of arches, too. In case of arch rib, symbolism was different. In the preference analysis, they showed a sensitive reaction in the background of building. In the results of the relativity preference and psychological factor, according to aesthetic, symbolism and orderliness, there was an effect on the background of building. And, there showed the high effect in order of aesthetic, orderliness and symbolism in the background of mountain and building. This study should be objective raw data of the arch bridge design for improving the urban landscape. In the future, aesthetic variables like colors or textures should be considered for more exact evaluation.

The trend of manycore hardware has recently evolved more quickly than expected. However, an operating system, which is software used for managing computer resources, is still optimized for a multicore system. To handle this issue, we started a research project called 'Research on High Performance and Scalable Manycore Operating Systems' in 2014. This article briefly examines the technology trends of manycore hardware and operating systems, and introduces the research areas and outcomes during the first stage of the project(2014-2017). The core technologies improving the performance scalability of manycore systems are publicly available, and anyone can use the source code or apply the ideas of the core technique to other research activities. In addition, the research plans of the second stage of the project(2018-2021) are also included.
