A Study on Characteristics of Landscape Color element on the Urban Waterfront
Younjoung Ji,Jungeun Lee 한국색채학회 2011 한국색채학회 학술대회 Vol.2011 No.10
According to changes in industrial structure, the advanced cities of the world are seeking new land use of the waterfront and new urban image based on it. According to this flow, starting with the Cheonggaecheon project, Korea is also making a lot of efforts to improve the amenity of the city through restoration and improvement projects of waterfront. However, unfortunately, the clear concept and improvement direction on city waterfront have not been established until now due to lack of research and history related to domestic city waterfront. Therefore, this study attempted to present the landscape color improvement direction to form eco-friendly waterfront landscape through the analysis on successful waterfront improvement cases in Nakanoshima water park of Osaka and Ashiya river of Kobe. The findings showed that basic colors of the landscape are formed according to the urban environment. And eco-friendly landscape is be formed by color elements of nature playing a role of accent colors of the landscape through restrained landscape planning of artificial color elements. Also, based on the result of analyzing chrominance of important artificial color elements , it could be seen that continuity of the landscape is formed because the average value of fixed landscape elements of city and waterfront shows about 10 chrominance around base colors. This study has the objectivity of research due to the analysis through quantitative color measurement of landscape colors on successful improvement cases of waterfront in Japan and is expected to be used as basic data on continuity of colors plan of waterfront to be progressed in the future.

경영에서 grab start와 track start의 운동학적 분석
김연정,이민형,원문학,김헌수 한국운동역학회 2000 한국운동역학회지 Vol.10 No.1
본 연구는 남녀 수영 선수 6명씩을 대상으로 grab start와 track start를 실시하여 두 집단간과 두 출발법간의 동작 특성을 운동학적으로 분석한 후 변인들을 정량화 하여 선수들에게 출발법에 대한 심층적인 이해를 제공하고 효과적인 훈련에 기여하도록 하는 것이 목적이며 실험으로 카메라 4대를 이용하였으며 분석을 위해 권(1993)이 개발한 Kwon3D 동작 분석 프로그램으로 3차원 영상 분석을 실시하였다. 결과의 통계 처리 자료로는 SPSS 프로그램을 사용하였으며 출발에 관련된 운동학적 변인을 수평방향과 수직방향에서의 인체 중심점 위치와 속도의 변화를 측정하였다. 위치 변화에서는 출발대를 떠나는 지점에서 남자 선수들은 수직 지향을 여자 선수들은 수평 지향을 함을 알 수 있었고 속도 변화에서 출발대를 떠나는 순간 track start가 속도값이 크기는 하나 두 출발법 사이에 유의한 차이는 나타나지 않았다. The research has the aim to analyze and find out kinematic features of grab start and track start between male and femail. With having selected 6 swimmers form each for this experiment four video-cameras(60 frames/sec) and control-box(length-2m, width-1m, hight-1m) to get real space coordinates were used. The DLT method was employed to obtain the 3-dimensional coordinates of the 25 body points for digitizing with Kwon3D Motion Analysis Package developed by Kwon, Young-hoo (1993). SPSS was used for statistic process. Kinematic variable were measured in start: The center of mass of body in horizontal and vertical, variation of velocity, entry distance. The following are the results. 1. In change of the body-center, the starting methods of man and women are same in horizontal directions, but in vertical directions the amount of women´s body changement is decreasing ever, while the amount of man´s body changement is increasing continuously with his foot off the start line. The change of the position and velocity in vertical directions is changing with the same tendency in case of starting ways of both man and women, but in vertical directions man´s amount of changement has steep increasing curve, and women´s one has decreasing curve. 2. Horizontal ANOVA analysis of body-center shows that starting method represent not such difference at taking-off moment but significant difference at initial moving point(F=237.016, p<.01). Vertical analysis shows significant difference in gender and starting method(for each F=31.132, p<.01, f=22.591, p<.01)

A Study on the Determinants of the Survivorship of Listed Companies in Korea
김영산,왕규호,SangGuePark,Su-YounJoung 한양대학교 경제연구소 2002 JOURNAL OF ECONOMIC RESEARCH Vol.7 No.2
Using the proportional hazard model developed by Cox (1972,1975), this paper empirically examinesthe determinants of sur-vivorship (or exit) of the listed companies in Korea Stock Ex-change. Our dataset comprises of 719 listed rms whose com-plete nancial statementsare provided by Korea InvestorsService(KIS),Inc. It coversthe period between 1980 and 1998. We ob-tain the following results. The rm size, R& D investment, thelargest shareholder's share and the time between establishmentand listing have favorable eects hasa negative eect. Surpris-ingly,the eggectsofnancial variablessuch ascapital-assetratio,operation income ratio and net income ratio turn out to be insignificant. The industry specific variables such as capital-labor ratio and concentration ratio are also insignificant.
