본 연구에서는 금강 유역(대청댐~금강하구둑)을 대상으로 RUSLE (Revised Universal Soil Loss Equation)를 활용하여 하천정비사업 전(2007년)과 후(2015년)의 연간 표토 침식량을 계산하였고, 이를 5단계의 class를 구분하여 해당 구간 별 표토침식면적을 산출하고 그 결과를 환경부의 토지피복 변화와 비교·분석하였다. RUSLE을 구성하는 각 인자를 생성하기 위하여 2007년과 2015년의 토지피복도, 국가기본 공간정보, 정밀 토양도, 연평균 강수량 자료 등의 다양한 공간정보자료를 활용하였다. 연구 결과, 연구지역에서의 연간 표토 침식량은 2007년과 대비하여 2015년에 class 1의 면적은 증가하였고, class 2, 3, 5의 면적은 감소하였으며, class 4의 면적은 증가하였다. 이러한 원인으로는 연구지역의 연평균 강수량의 감소, 생태공원조성과 이로 인한 인공시설물 확대, 농경지 감소 등으로 인하여 대부분의 지역에서 연평균 표토 침식량이 감소된 것으로 사료된다.

This study extracts the plan that is suitable to open education through the assessment and analysis of the open education environment. For this, the questionnaire survey of teachers at the elementary school in Kyengsang-bukdo was used. The results of this study can be summarized as follows; 1) In the estimation of satisfaction on the classroom environment for open education, although the score of "Comfortableness" is high, the scores of "Variety", "Convenience", and "Silence" are low in satisfaction. 2) The image on the classroom environment is highly regarded in general in "Stability", "Nobleness" and "Activity". However, it is necessary to devise some methods to improve the image on "Stability", when removing the wall between classrooms and corridors. 3) To improve the satisfaction and image associated with classroom environment, it is important to maintain suitable size of school and density of classroom. 4) The factors of satisfaction and those of image are correlated each other. Thus, to enhance the total image on the open class, it is necessary to improve the whole classroom environment.

This thesis examines the shape, organization, background, and significance of the classroom space in highly appraised elementary schools since the inauguration of public education in modern times in the fields of education or architecture. This thesis acknowledges that classroom shapes comprise an auditorium-like space for a large-scale study group, a square-shaped classroom designed for simultaneous teaching for single class, and bent and L-shaped classrooms for various learning activities. Whereas the square-shaped classroom for simultaneous teaching which has lasted until now evolved around 1870, the post-1930s era witnessed the emergence of a composition in which classroom and outside space are associated, of an atypical classroom, and of Functional Unit where common space and classrooms are assembled. It is deemed that the emergence of the atypical classroom comes from the reinterpretation of learning and space pursuant to progressive pedagogical philosophy and child development theories and functional architecture theories. Thus, this thesis verifies that school construction and learning space can be newly created and the synthesis between education, child development studies, and architecture is a prerequisite to such a creation.

Recently, the Korean government announced a plan to activate renewable energies, with focus on clean energy sources such as solar and wind power as the core and the goal of achieving carbon neutrality by 2050. Unlike other photovoltaic (PV) systems, offshore PV installations are advantageous for large-scale expansion because of the ease of securing sites; they also enable lowering the power generation costs based on construction of large-scale power facilities of megawatt class or higher owing to low noise and landscape damage. However, any power generation should proceed with consideration of the special environmental conditions of the ocean. Above all, when installing large-scale facilities, it is important to reduce fluctuations of the structure and secure stability to actively respond to waves. This study is concerned with the development of a floating body technology that actively responds to waves so as to enable commercialization of offshore solar power. A unit platform for research and development on offshore PV generation was installed in the Saemangeum sea, and the structural fluctuations and stability were analyzed to ensure conformity with the major performance indicators.

This paper reviews KSG2010(Korean Industrial Standard for Student's Desk and Chair) compared to student's body size and suggests its new design guideline. It is found that the chairs are too high to sit straight up, and it is not easy to sit at student's ease because of backbone rest bar not existed in a right place. It is also found that the desks are too high to sit at desk to accept student legs under a drawer. So student's visibility range becomes decreased and it produces a harmful posture for eye protection. This paper also found that step number of student's desks and chairs needs to expand to 12 different steps inserted 5 steps between the existing 7 steps. A reason is that there is gap between the sizes of desk and chair and human height and width. Another reasons is that it is difficult to arrange desks and chairs appropriated to student body sizes in a class room.
