Since creativity has been emphasized and creative problem solving has also been a big topic recently, various kinds of research works have proceeded. Among them, this paper focuses on abstract thinking and growth mindset, which affect on problem solving. Also, this paper analyzes what kinds of relationships time perspectives and smart-phone addiction have with the two factors and how they influence on them. In order to do so, we survey on 441 primary, middle, high school, and college students. Our analysis results cover the relationships among the two factors, smart-phone addiction level, present-hedonic perspective, and future time perspective. In addition, we analyze the relationship among the factors with a structural equation model. By doing these, we propose educational alternatives in terms of time and plan to improve our adolescent's abstract thinking level, which helps their problem solving skills and their academic achievement.

For the most efficient operation of water mains, 124 head losses in domestic water supply steel mains were measured to provide the values of friction coefficient and the variable affecting the deterioration rate of Hazen Williams' and Darcy-Weisbach's friction coefficient. The experimental results show that pipe age is governing the friction coefficient of large mains (Diameter > 1100 mm). On the other hands, pipe age and pipe diameter are affecting the variation of carrying capacity for small mains (Diameter < 1100 mm). The friction coefficient of water mains in foreign countries is higher than that in Korea by about 5 to 10 in Hazen Williams' C value. The growing rate of roughness height of domestic water main is about 0.41 mm/year which is higher than the average of United States of America. So further study is required to find out what causes the serious deterioration rate.

This paper presents an experimental study on the discharge head of Cherepnov water lifter that was continuously operated with the aid of the siphon. The energy used by the Cherepnov water lifter is derived from the potential energy ofthe water itself. The lifter consists of three interconnected tanks and five pipes, one of which is open and two others are hermetically sealed. The effects of varying operating parameters such as the tank and pipe size, the ratio between head of discharge and drop height were analyzed. As a result, factors that can maximize the efficiency and increase the average delivery rate were indentified. When the ratio between head of discharge and drop height is about 0.5, the efficiency of Cherepnov water lifter is maximized. In order to design the efficient Cherepnov water lifter, the discharge head of the Cherepnov water lifter should be assigned to be twice as much as the drop height. The effect of tank size on the efficiency is less than 5%, while the effect of the pipe size is not negligible. The larger the pipe size is, the more the efficiency increases.

This study examined the relationships between learners' perception on parents academic involvement, academic self-efficacy, school adjustment, and career maturity, and also to analyze the hypothetical structural equation model relating three independent variables to career maturity. The participants were 443 sixth grade children(218 boys and 225 girls). The findings are as follows. career maturity positively showed the highest correlations with learners' perception on parent academic involvement, and academic self-efficacy. The findings revealed that learners' perception on parent academic involvement indirectly influenced career maturity mediated by academic self-efficacy and school adjustment. Furthermore, school adjustment displayed the highest direct effect on career maturity, whereas learners' perception on parent academic involvement showed the highest indirect effect on career maturity. It was discussed to develop and mange career program, career education, and career counseling effectively for elementary school children.

Purpose of study: The purpose of this study is to propose an education for biblical Shalom for the future of education in relation to UNESCO 2050. Research content and method: The education for Shalom is about experiencing Shalom in fellowship with God. Moreover, it expands that shalom into relationships with self, neighbors, the earth, and technology, and then helps achieving balance between Shalom and those mentioned above. In order to provide education for Shalom, this study presented five relational dimensions of experiencing Shalom. First, the joy of serving God and neighbors in a proper personal relationship with God is most important. Second, it is the joy of building a right community and living in it through harmonious relationships with neighbors. Third, it is the joy of living in a harmonious relationship with nature. Fourth, it is the joy of being respected for human rights that are dignified as the image of God and living while enjoying rights. Fifth, it is the joy of enjoying fair use and benefits from technological innovation without being alienated, excluded and treated unfairly, or receiving disadvantages. Based on that, a model of education for Shalom has been developed. Conclusions and Suggestions: The educational model for Shalom forms view of values, knowledge, and human nature through the Bible. It consists of learning strategies to maintain a balance between the form of knowledge and the five relational dimensions. This model has a structure that carries out education for Shalom while interacting with each other.

Since the phases and patterns of the climate adaptability of vegetation can greatly differ from region to region, an intensive pixel scale approach is required. In this study, Partial Least Squares (PLS) regression on satellite image-based vegetation index is conducted for to assess the effect of climate factors on vegetation productivity and to predict future productivity of forests vegetation in South Korea. The results indicate that the mean temperature of wettest quarter (Bio8), mean temperature of driest quarter (Bio9), and precipitation of driest month (Bio14) showed higher influence on vegetation productivity. The predicted 2050 EVI in future climate change scenario have declined on average, especially in high elevation zone. The results of this study can be used in productivity monitoring of climate-sensitive vegetation and estimation of changes in forest carbon storage under climate change.

The ICT convergence and intelligence information technology has many influences on the whole smart society in the $4^{th}$ industrial revolution era. However, preparations degree of our country is not high as for the intelligence information technology. It is not easy to adopt a new technology on education for cultivating the creative future human resources to match a pace with intelligent smart society. In addition, it is hard work to find and derive the appropriate technology for education because proper and effective proof includes much difficulties. Therefore, this study develop the e-learning standard technology framework through the derivation of educational standard technology element and the suggestion of medium and long term standardization framework for the intelligence information society.

최근 환경부에서 발표한 국가물관리기본계획에서 수자원 총량 중 생활·공업·농업·유지용수의 이용량은 365억m³/년으로 약 29.4%로 발표되었다. 유지용수를 제외한 농업용수 이용량의 비중은 약 60.5%이며, 이 중 약 80%가 논에서 활용되고 있다. 이러한 농업용수 이용량 중 사용되지 않고 하천으로의 방류량이 존재하는데 이를 관개회귀수량이라하며, 농업용수의 약 35%가 하천으로 회귀된다 발표하나 지역에 따른 편차가 존재하기에 정확한 회귀수량을 산정하기엔 미흡한 실정이다. 따라서 본 연구에서는 네트워크 모형을 통한 용배수로 구축 이후 회귀수 정량화를 하고자 하며, 정량화를 위한 네트워크 모형은 EPA-SWMM(Storm Water Management Model) 모형을 활용하였다. 해당 모형은 미국 환경 보호국(U.S. Environmental Protection Agency, EPA)에서 개발한 네트워크 물리모형으로 다양한 환경적 요소에 따른 수문 영향을 확인 가능한 모형이다. 해당 모형의 다양한 네트워크 기능을 통해 논배수로 네트워크를 구축하여 회귀수 정량화를 진행하고자 한다. 논배수로 네트워크를 구축하기 이전 현장조사를 진행하였다. 현장조사를 통한 용수계통도를 작성하였으며, 모형의 입력자료로 필요한 네트워크 용배수로관 표고값을 측량하였다. 이후 현장조사 및 측량 자료를 활용하여 네트워크 물리모형의 입력자료 구축을 진행하였으며, 해당 자료 구축은 지리 정보 시스템 중 ArcGIS와의 연계를 통해 구축하였다. 모형의 수리학적 입력자료는 해당지역의 계측자료를 활용하였으며, 필지 사이의 내리흐름 및 펌프를 통한 용수 또한 네트워크 물리모형의 기능을 활용하여 구축하였다. 이후 계측자료와의 비교를 통한 매개변수 보정을 진행하였으며, 전체 논배수로에 대한 농업용수의 흐름 및 회귀수량을 분석하였다. 해당 연구를 통해 농업용수의 회귀수 산정 및 지역 편차에 따른 회귀수 정량화 등의 연구에 활용될 것으로 기대한다.
