The Sihwa River was first planned to be a fresh water lake, but it failed due to serious environment pollution. During times of destruction and regeneration, changes of ecosystem of Sihwa River was visible, especially the algal ecosystem. It's because many seasonal birds pass through the place. This paper analyzes the changes of algal ecosystem of Sihwa River based on eight ecosystem indices. Moreover, using gradient descent, COD is expressed has a function of three ecosystem indices selected from above which is newly defined as SEI, Sihwa Ecosystem Index. In conclusion, we can observe the current ecosystem more easily without its actual data, but only with informations of the ecosystem.

The United States (CS2013) and Japan (J07-CS) constitute a standard informatics curriculum that reflects a changing society at the level of higher education. This study analyzed the change of standard curriculum in the United States in order to provide implications for the standard composition of higher education curriculum in Korea. The subjects were composed based on the analysis of current status of university curriculum and content knowledge in Korea. As a result of the research, the Informatics curriculum in the United States has evolved into a curriculum reflecting the changing computing environment. The information curriculum of domestic colleges included only 52% of the knowledge area of CS2013. The purpose of this study is to provide an example of the composition of subjects based on the curriculum composition policy of Japan and to provide a basis for the curriculum composition without the standard informatics education course of the college in korea.

본 논문에서는 수학교육용 소프트웨어에서 확률적 현상을 경험한 이후 과학 그래프 해석에 있어 확률론적 관점을 도입하여 해석하는 학습자의 관점의 변화를 제시한다. 이 연구에서 11명의 고등학교 1학년 학생은 수학교육용 소프트웨어인 지오지브라(GeoGebra)를 활용하여 학습자가 평면 상에서 수직선이나 반원 위에 점을 찍는 활동을 통하여 기하학적 확률을 경험하였으며 이와 같은 경험을 토대로 물의 상평형 그래프를 해석하였다. 물의 상평형 그래프에 나타나는 얼음(고체), 물(액체), 수증기(기체)의 상태 변화에 대하여 각 상태가 나타나는 온도-압력의 영역 간의 경계에 대하여 학습자는 기하학적 확률을 적용하여 해석하려고 하였으나 경계선 위의 온도-압력의 물의 미시적 구조를 표현하는 과정에서 4명의 학생만 확률론적 관점으로 해석하고 그렇지 못한 학생들은 상태의 공존을 물질적 관점이나 과정적 관점으로 이해하였다.

The purpose of this study is to develop and implement education programs for the science high school students who entered by affirmative action. The program was developed with the goal of bridging the educational gap through effective school adaptation of these students. The program was applied, and then pre-post academic self-efficacy and self-elasticity tests and interviews were conducted. 70 students participated in the before entrance program, 56 of them participated in the summer vacation program, and 36 of them participated in one-on-one interviews related to the effectiveness of the program. In the test results, there was a significant difference only in self-elasticity, and in the interview results, it was found that the program was very helpful in terms of academic and school life. Suggestions for further support and studies were provided.

The purpose of this study was to investigate the relationship between the characteristics of beauty information in the SNS environment and consumer attitudes and loyalty of high school students. The subjects of this study were high school students residing in Gwangju, and a total of 375 copies were used for the final analysis. The collected data were analyzed using SPSS V.21.0 program. Summarizing the study results, interactivity and usefulness were key factors in the relationship between beauty information characteristics and high school students' attitude and loyalty in the SNS environment, and information provision, playfulness, and vitality were derived as major factors. Based on the above result rule, it is expected that it will be used as a data for presenting the direction for collecting the correct information in the SNS use of teenage consumers and establishing marketing strategies for beauty companies.

Leading the fourth industrial revolution era requires science and technology strategies that establish original research directions at the national level. To this end, it is necessary to look at the research and development activities for the fourth industrial revolution of technology-leading countries. In this study, the research programs of the U.S. Intelligence Advanced Research Projects Activity(IARPA), an organization focusing on cutting edge research on science and technology information such as artificial intelligence, are investigated by using network analysis. The findings show that, resolving around the information identification and forecasting, decision making and cybersecurity clusters, IARPA's research programs largely focus on finding hidden information and predicting specific events, supporting decision making by considering changes in and outside organizations or establishing cybersecurity. Also, this study finds that China and Japan, representative technology-leading Asian countries, refer to the research programs of IARPA to establish their science and technology policies. The results of this study suggest implications for Korea's science and technology policies in response to the fourth industrial revolution era.
