권오선(Kwon Oh-Seon),임영환(Lim Yeong-Hwan) 대한건축학회 2011 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.31 No.2(계획계)
In 1970, the movement of heavy chemical industry oriented economic structure from manual industry started to change overall parts of Korea such as economic and social structures. The high growth of Korean Economy has centered on the city and has effects on overpopulation of the city. For this reason, the phenomenon of social infrastructure became unavoidable. Therefore, the demands of buildings rapidly increased and effected on overall changes of architecture. Also, it had direct influences on the current centralization, Manhattanization, and mass production of buildings in the city. Then, there has been additional investment in building constructions, and the building industry has been even more activated. In this rapidly increased building industry stated to appear functional, environmental, and aesthetic problems with the life-cycle of the buildings in 1990. Remodeling was one of the alternatives for the deterioration of buildings. Especially for the deteriorating office buildings, new working facilities and environments are required, and the remodeling is considered as one of the solutions.

이륜차 CVT(Continuously Variable transmission)의 가동플랜지는 그 내부에 롤러가 들어가 있어 이 롤러의 구동으로 벨트가 가동풀리의 형상을 따라 움직이게 된다. 롤러의 움직이는 궤적은 바로 가동플랜지 내부의 프로파일형상과 매우 밀접한 관계를 맺고 있다. 본 연구에서 현재 이륜차 CVT에 사용되고 있는 가동플랜지의 특성을 해석하였다. Driving flange used in motorcycle CVT(Continuously Variable Transmission) has a roller inside. The belt moves according to the track of driving pulley by the actuation of this roller. The orbit of this roller is closely related with the inner profile figure of the driving flange. In this study, the characteristics of driving flange used in motorcycle CVT was analyzed.

Pocket machining is metal removal operation commonly used for creating depressions in machined parts. Numerically controlled milling is the primary means for machining complex die surface. These complex surfaces are generated by a milling cutter which removes material as it traces out pre-specified tool paths. To machine a component on a CNC machine, part programs which define the cutting tool path are needed. This tool path is usually planned from CAD, and converted to a CAM machine input format. In this paper I proposed a new method for generating NC tool paths. This method generates automatically NC tool paths with dynamic elimination of machining errors in 2½ arbitrary shaped pockets. This paper generates a spiral-like tool path by dynamically computing optimal pockets of the pocket boundary contour based on the type and size of the milling cutter, the geometry of the pocket contour and surface finish tolerance requirements. This part programming system is PC based and simultaneously generates a G-code file.
現行 體育敎育課程에 對한 敎師들의 診斷 : 女子 中學敎를 中心으로 Focus mainly on girl's middle school

In this paper, I analyed the curriculum of physical education through the physical education teachers of girls' middle school in Dae-gu. From this research, the following conclusions are drawn: 1. Generally speaking, athletics, gymnastics, individual and personal games, ball games, and swimming can't be taught well because of their high hardness. Let is a phenomenon which is caused by only arrangement of learning contents without considering individual characteristic and differences of students. Therefore it is asked to evaluate the current curriculum of physical education again. 2. Table tennis and badminton can be played of a limited place. Besides, girl students can become interested in them easily. So, basic and standard teaching is needed in order to continue the games as life-time sports after graduation. 3. Swimming, skate, archery, shooting, tennis and softball are not taught well because of facilities. It is the matter solved by the authorities. 4. In the case of swimming and skate, facilities and places are limited, moreover the students don't have much opportunity to contact with them, and they are seasonal sports. Therefore concentrative teaching is asked during the weekends and vacations.

In this paper, the theoretical study is performed on the active Remote Center Compliance (RCC) mechanism of the robot manipulator. The institution method of compliance or impedance is applied for simple assembly operation such as peg insertion. It is expected that the proposed method can be used for the analysis of 6-DOF robot manipulator. The results can be summalized as follows : 1) In case of underdamping, the repulsion occurs in the process of the peg insertion. 2) To prevent peg inclination, the origin of the compliance coordinate system must be located on the contact force line. Also inertia matrix, damping matrix, and stiffness matrix must be diagonal.
