Aircraft carriers need to maintain an orderly flow of aircraft in order for military ships to conduct combat through aircraft. Maintaining aircraft flow is an important factor in strengthening ship and aviation safety. In order to maintain aircraft flow, it is essential to develop a state-of-the-art air control system that provides higher quality control information by simultaneously accommodating radar-based monitoring information and monitoring information based on CNS integrated technology. Based on this point, this study describes the function and operation method of specific control equipment for the operation of the Aviation Support System and Air Traffic Control System required to operate light aircraft carriers in Korea based on overseas cases. 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.

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)

사회연결망분석을 활용한 유아 또래관계 유형 탐색

최연철 한국유아교육학회 2012 유아교육연구 Vol.32 No.2

유아또래관계 유형을 탐색하기 위하여 유치원과 어린이집 26개 학급의 유아들에게 좋아하는 유아와 싫어하는 유아 각 3명을 선정하게 하였다. 사회연결망분석의 통계치 가운데 3개의 중앙성 지표(연결정도중앙성, 인접중앙성, 사이중앙성)와 각 중앙성의 중심화 지표를 토대로 또래집단의 유형을 구분해보았다. 연구결과 각 중앙성의 평균이 높은 학급과 낮은 학급의 또래관계가 서로 다르게 나타난다는 것을 알 수 있었다. 예를 들어, 연결정도중앙성 평균이 높은 학급에서는 한 명 또는 소수의 유아가 또래관계에서 핵심적인 역할을 하고 있는 반면, 평균이 낮은 학급일 경우 또래관계에서 중요한 역할을 하는 유아의 수가 상대적으로 많다는 것을 알 수 있다. 한편 중앙성 평균이 비슷한 집단이라고 하더라도 중심화의 정도가 높은 학급은 낮은 학급에 비해 중앙 집중의 정도가 높다는 것을 알 수 있었다. This study used social network analysis (SNA) to discover peer relationship patterns. Young children in 36 classes were asked to nominate three "like the most" and three "like the least" children in their respective classes. Using Net Miner 4.0 and R program, the number and kinds of ties of connection each member of a class was ascertained. These ties, called centrality, are a measurement indicating how well connected each student is to the social network of the class. Once the many complex sub-measurements of centrality are completed, patterns begin to emerge. For example, one or a small number of children were centers of the social networks in a class with a high degree centrality whereas many children took central roles in a class with low degree centrality. The study offers a full description of the SNA process used and defines the measurements and their roles in constructing the social network structure. The implications of understanding childhood peer relationship patterns through SNA are many and all are based on the insightful knowledge that SNA provides in linking children's development to the interactive, relational influences in their social network.

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.

근린공원의 주·야간 이용행태에 관한 기초적 연구

최연철,김진선 淸州大學校 都市·地域開發硏究所 2000 都市·地域開發硏究 Vol.8 No.1

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.

도시근린공원의 야간이용행태와 조도분포

최연철,김진선 청주대학교 산업과학연구소 2001 産業科學硏究 Vol.18 No.2

This study was to analyze correlation between behaviors of night uses and distribution of illumination levels of a physical environment factor. The results of this study are as follows, 1. The distribution of illumination levels by types of behaviors of night uses was shown variously at urban neighborhood parks. The average illumination level was 7.46 lx for standing activities, 8.23 lx for sitting activities, 7.55 lx for riding activities, 5.79lx for sports and plays, and 2.50 lx for practical activities 2. When comparing average illumination levels by types of behaviors of uses with the standards of illumination levels of the Korean Industrial Standards, they coincided with minimum illumination levels of standard illumination levels for the whole parks, and were higher than the total average illumination levels of present urban neighborhood parks. 3. The distribution of illumination levels by types of behaviors of uses by spaces were shown variously. When comparing it with average illumination levels by spaces of present urban neighborhood parks, present average illumination levels by spaces do not have suitable illumination levels for functions of spaces. 4. As the result of canonical correlation analysis between night uses and distribution of illumination levels, correlation between two factors was not shown - it is judged that night uses at urban neighborhood parks are mixed irrespective of functions of parks due to unsuitable average illumination levels by spaces of present urban neighborhood parks.

The purpose of this study is to research and analyze the distribution of night illumination level at urban neighborhood parks and to show its characteristics. And this is used basic data ensuring safety and satisfying aesthetic and psychological desires of people who use urban neighborhood parks at night. To research and analyze the distribution of illumination level at urban neighborhood parks at night. To research and analyze the distribution of illumination level at urban neighborhood parks, I selected 8 urban neighborhood parks as the subject of research in this study, set the measuring standard of illumination level, and measured the illumination level by the measuring standard. The results of this study are as follows; 1. Currently, total average illumination level of urban neighborhood parks was lower than the minimum standard of illumination level I KS A 3011-1993. 2. Average illumination level of each place in urban neighborhood parks appeared variously from low level to high level. But this was lower than the minimum standard illumination level in KS A3011-1993 like total average illumination level. 3. The higher was total average illumination level of urban neighborhood parks, the more various was brightness of places. Although users' aesthetic and mental desire or behavioral aspect relate with safety cannot be found by only survey and analyses of illumination level, it is judged that first, illumination level of the standard of the lightness should be analyzed to find user's mental states and behaviors in external space at night. Therefore, it is considered that this study, which analyzed characteristics illumination level as basic data, has a significance. The study continuing for other illuminative environmental factors suitable in the place is required because the brightness of places may not be measured by only illumination level. And the proper illumination level in outdoor places should be showed in considering psychological and behavioral aspects of human as people may have their own sense of brightness.

한국의 뮤지엄 진흥정책과 박물관학의 성과와 전망

최연철 한국박물관학회 2009 博物館學報 Vol.- No.16·17

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.
