본 논문은 진공을 이용한 흡착방식과 바퀴형 이동방식을 이용하고 환경 탐지용 센서를 부착한 벽면 이동형 로봇의 구현에 관한 연구로서, 대형 구조물의 안전 검사 및 위험한 시설물의 보수 작업등을 보조하기 위한 목적이 있다. 로봇의 무게에 따른 중력을 견딜 수 있도록 강력한 진공흡착방식을 고안하여 다양한 벽면재질에도 견딜 수 있도록 설계하였으며, 바퀴형 이동방식을 택하여 높은 이동성과 제어 능력을 고려하였다. 또한 환경 감지를 위한 센서와 카메라를 부착하여 시각정보 등 유용한 정보를 관리자와 통신을 통해 교환할 수 있도록 하여 지능능력과 활용성을 갖추었다.

건물 및 주택의 가구배치나, 인테리어 디자인 등을 신규로 구성하거나 재배치하는 것은 고비용의 작업일 뿐만 아니라, 사용자가 정확히 판단하기 어렵다. 가상현실 시스템을 적용하면 공간적, 물리적 제약에 의해 현실 세계에서는 직접 경험하지 못하는 상황을 간접 체험할 수 있어 재배치에 대한 비용 및 시행착오의 오류를 줄일 수 있다. 따라서 본 논문에서는 EON Studio를 이용하여 건물 내부의 인테리어를 바꿔가며 디스플레이 할 수 있는 실내 인테리어 시스템 프로토타입을 제시하고자 한다. 현실 건물 내부와 가구를 EON Studio를 통해 구축한 후 회전 및 이동을 통해 재배치 도록 하였다. 구현된 시스템을 통해 제안된 인터페이스가 공간 배치 응용 분야에서 유용성 이 있음을 확인하였다.

It is well known that the low achievement students are easily affected by the ways how the materials are organized and presented. So the studies on trying to find how those students' responses are differed according to the organization or presentation of the materials are necessary. This paper was based on the results of Korean Elementary 3 Grade Students National Diagnosis Assessment on Basic Scholastic Ability in area of mathematics. We analyzed students responses through combining the percents of correct answers with the assessment items. After that, we identified the properties of low achievement students in mathematics and presented some guides which, we thought, are helpful for improvements of mathematics textbooks and teacher guide books.

Previous studies showed that many secondary school students and teachers have difficulties in distinguishing the phenomena of dissolution and diffusion, as well as the phenomena of diffusion and effusion. In this study, currently accepted term definitions of dissolution, diffusion and effusion were searched from the IUPAC Gold Book and the physical chemistry textbooks, and the points to differentiate the definitions were sought. Also, the term definitions of these three phenomena in the secondary school text books and the college general chemistry textbooks were surveyed and compared to the currently accepted definitions. It was found that dissolution is formation of one new phase from mixing two phases, while diffusion is the migration of matter down from the concentration gradient. The "concentration gradient" is considered to be a key point to distinguish diffusion from the dissolution. However, the concentration gradient was not mentioned in the definitions of diffusion in most of the secondary school textbooks and the college general chemistry textbooks. Effusion is differentiated from diffusion by the gas molecules escaping from the container through a tiny hole without collision. The definition of effusion was not found in most of the secondary school textbooks.

The purpose of this study is to suggest some activation plans of vocational home economics high school education by analyzing the actual conditions of vocational home economics high school education and surveying teachers and students' recognition and their needs toward the present vocational home economics high school education. The data were collected through reference analysis. questionnaire and interview method. They were analyzed using SPSS. The outline of this study was as follows: First. some data for examining the development trends of vocational home economics were collected especially in terms of the social and economical change related to vocational home economics education. the development of vocational home economics education based on the current curriculum. and some trends of vocational home economics education in foreign countries. Second. the real conditions of vocational home economics high school education were analyzed according to the real conditions of curriculum management in vocational home economics high schools. Based on this result. a questionnaire was designed to survey teachers and students' recognition and their needs. The items consisted mainly of the curriculum management and satisfaction of school life. Third. some activation plans of vocational home economics high school education were proposed in terms of management system(3 items). curriculum management(5 items). security of teachers and their expertise(4 items). and administration and finance(3 items).

This study is related to reinforcement of the continuity between Nuri curriculum and elementary mathematics curriculum emphasized by 2015 revised national curriculum. Considering that teachers tend to rely much more on textbooks than on curriculum, we analyzed the continuity between math-related activities of Nuri manuals for teachers and the elementary mathematics textbooks and aimed to suggest several ways for securing the continuity based on the result of analyses. To do this, we compared and analyzed Nuri manuals (for ages three to five) for teachers and the first and second grade mathematics textbooks in three aspects: mathematical contents, mathematical terms and symbols, and mathematical processes. We adopted the same analysis framework including continuity, discontinuity and reverse continuity as the study on the continuity between Nuri curriculum and elementary mathematics curriculum. As a result, the results of analyses were revealed in three aspects, respectively. We also discussed the results and suggested some implications for securing the continuity of Nuri manuals for teachers and the elementary mathematics textbooks and for revising curriculum and its materials such as textbooks, workbooks or manuals for teachers.
