This study aims to clarify the preference of the hedge, on focusing the height, density, width of the hedge, which gives limited dwelling space continuity with outer space, promotes the naturality to dwelling environment, and plays an important role as green space in city. For this, it is performed statistical analysis by field survey, by classifying the hedge as planting pattern, and synthesizing the photograph. Therefore, the results of this study are as follows : 1. In the preference of height of the hedge, when only the hedge is composed, 1.5M is preferred, and when the hedge with deciduous tree, with needle-leaf tree, 1.25M is preferred. 2. In the preference of density of the hedge, which are perfect density, in case of the hedge, which are almost density, in case of the needle-leaf tree, are preferred. 3. In the preference of width of the hedge, 0.4M is preferred. 4. In the preferential factors of the hedges, the preference of the hedge is mainly influenced by density. As the result of multiple regression analysis of visual preference as the height, the density, the width, and the regression equation are as follows : Visual Preference = 0.094+0.412(density)+0.370(height)+0.177(width)

This study analyzed the effects of illumination on psychological accessibility from a view of satisfaction of night use at urban neighborhood park for actual night users. For this, we have classified the effects of illumination as five sampled independent variables from 12 effects of illumination, and tested the relationship with satisfaction of night use of a dependent variable by multiple regression analysis. The results of this study are as follows; 1) The effects of illumination for night use at urban neighborhood park were divided into five factors; (1) direct effect, (2) effect of promoting use, (3) effect of ensuring security, (4) effect of preparing landscape in the night time, and (5) psychological effect. Among independent variables indicating characteristics of effects of each illumination, uneasiness at night use was high. 2) In a multiple regression model, when other conditions were not changed, the value of security of night use (X\ulcorner) had maximumly an affect on the value of dependent. And, the value of danger to meet the depraved(X\ulcorner) had minimally an affect on the value of dependent variable. 3) For the contribution of security of nigh use(X\ulcorner) and brightness of present using space(X$_4$) to satisfaction of night use(Y) of dependent variable, they had a nearly equal effect on that, and showed about 2 times importance compared to familiarity with park(X\ulcorner) and the beauty of park(X\ulcorner). Also, they showed about 7 times contribution to satisfaction of night use compared to danger to meet the depraved(X\ulcorner), which had minimally an affect on the value of dependent variable, as the most important variables. 4) For the effects of illumination on satisfaction of night use, the effect of ensuring security - pursues security of park for the general rather than security for the specific class or subject - and direct effect to offer proper brightness in using space relatively affected on it much compared to psychological effect, effect of preparing landscape in night time, and effect of promoting use. A research on the psychological effects among the variables related to illumination as well as physical circumstances such as the height, location, direction of illumination should be studied.

The purpose of this study is to suggest basic data of environmental plans and designs for the future by analyzing patterns of behavior of day and night users in use of neighborhood parks. This study selected 3 neighborhood parks as the subjects to survey and analyze behavior patterns for neighborhood parks, and analyzed characteristics of day and night behavior patterns. The results are as follows; 1. For day and night behavior patterns, behaviors with standing(A) and behaviors with sitting(B) amounted to 70 percent or more; The purposes of using neighborhood parks are limited to movement, passage or rest. 2. The range of behavior patterns of daytime by behavior types is wide in the whole areas, and for the night they occurred in a specific space or place where lights are installed. 3. The age of day and night users was shown differently; Various ages used neighborhood parks in daytime, and teenagers and twenties used much in the night. 4. For patterns of use by follow-up survey, the movement line showed similar patterns in day and night but illumination levels influenced much night. Teenagers preferred dark places and twenties and thirties relatively light places. 5. Places of low density of pattern or use occurred a lot in night use means that necessary illumination levels are different by behavior patterns in the space. A place where suitable illumination levels are not maintained in the space may not accept the original function of the space, and it is replaced with other functions, or the using rate decreases. This study found patterns of day and night use for neighborhood parks and analyzed the characteristics by doing behavior observation and follow-up survey at the same time. But, patterns of night use may be different by the illumination level of the basic standard of lightness and psychological factor from the space, so studies on illumination levels or psychological aspects should be done in future.

한국박물관의 근현대사를통시하고있는양현미 교수의「한국뮤지엄 진흥의 정책의 성과와 과제」는 일제강점과 미 군정 그리고 전쟁과 재건 국가적 역통기를 숨 가쁘게 달려온 한국의 근 현 대사와 맞물린 한국 뮤지엄의 현황을 잘 보여주고 있다. 특히 한국 뮤지염이 지난 100년 역 사를 통해 이루어낸 양적 증대가 “문화적 수요에 부응한 것이 아니라 정치적 고려 하에서 이루 어진 하드웨어 중심의 공급지- 중심적인 정책 에 근거하였기 때문에 박물관들은 운영이 부실할 수밖에 없었다 ” 고 지적하면서도 , 국민의 정부와 참여정부에 들어서 진행된 ‘하드웨어에서 소 프트웨어로전환’ 과정을통해 자율과지원의 중요성을상기시키면서 뮤지엄에 대 한안정적 인 국가적 지원 시스템 구축이 필요함을 역설하고 있다.

항공모함은 군용함정이 항공기를 통하여 전투를 수행하기 위하여 항공기의 질서정연한 흐름유지가 필요하다. 항공기 흐름유지는 함정과 항공안전을 강화하기 위한 중요한 요소이다. 항공기 흐름유지를 위해서는 현재 운용 중인 레이더 기반의 감시정보와 CNS 통합 기술에 기반을 둔 감시 장비들에 의한 감시정보를 동시에 수용하여 보다 양질의 관제정보 를 제공하는 최첨단 항공 관제시스템을 개발이 필수적이다. 이를 위하여 본 연구는 이러한 점에 착안하여 해외 사례를 기초로 우리나라에서 경항공모함을 운영하기 위해 요구되는 항공지원시스템(Aviation Support System) 과 항공관제장비(Air Traffic Control System)의 운영에 대해 구체적인 관제 장비의 기능 및 운영 방법 관하여 기술 한다.
