주택단지 옥외공간은 거주자들의 여가활동, 휴식공간, 야간활동 등에 사용된다. 이러한 경향에 의하여 주거단지의 옥외공간이 매우 중요한 공간으로 인식되고 있다. 그러나 옥외공간은 야간이용이 빈번함에 불구하고, 각 공간의 조명계획은 조명기구의 선택과 배치 그리고 조도계획이 부적합하다. 이러한 관점에서 본 연구는 옥외공간의 빛의 본질을 파악하고, 옥외공간별 조명환경을 측정 시뮬레이션 분석하였다. 본 논문은 이 사례를 통하여 공간별 목적에 맞는 조도기준 및 조명계획의 방향, 합리적인 유지 방안을 제시하였다. Outdoor spaces are used for recreation, rest area, and night activities of residents. By these tendency, outdoor space is recognized as a very important space in residental areas. However, outdoor space is frequently used at night but lighting plan for these spaces is not suited for the selection of luminairce, arrangement of luminaires and planing of illuminance. From this point of view, this paper investigated the essence of light in outdoor space, analyzed different outdoor luminous environment and performed simulations. This paper finally suggested recommended level of illuminance and lighting plan of such spaces.

Daylight response dimming systems are one of the control system of artificial lighting according to available daylight. Though such systems are efficient control systems on the energy and environment, these systems are not widely because of fixed shading system without variations of shading system on the available daylight quantity. Therefore the purpose of this study is to analyze influential factors such as reflected and transmitted daylight on the performance of daylight response dimming system caused by shading systems with mock-up and RADIANCE simulation data.

This study, base on the result of political consciousness among the poor in 2004 social survey, attempts to identify political attitudes and voting behaviors of the poor in Busan, Ulsan, and South Gyoungnam Province with 2004-2005 interview result. In case of the political consciousness result from 2004 social survey, the level of political interest, efficacy, and trust were comparatively low compare with that of political participation. The results of the interview indicate that why the poor has these levels of political attitudes: the poor show political distrust since they still severely suffer from economic strain in the every day life and corruption of politics negatively influences on political disbelief of the poor when current economic situation was not recover yet. The poor show not positive types of political participations such as political donation, and active involvements to political campaigns but passive types of political participations. According to voting behaviors analysis of the poor, we might say that regionalism is still important impact of voting behaviors even though we could find other major influences such as generation and ideology variables. Therefore, this study suggests that voting behaviors of the poor is mainly based on irrational and apolitical motivation. Moreover, supporting political party, candidate, and policy were not involved in cognitive or evaluative orientation but affective orientation such as distrust of current government. Finally, this study concludes that these types of political consciousness and behaviors of the poor are reponses of the their economic strain and distrusts of current politics. Therefore, in order to integrate the poor as one of social members, our society need to focus on policy that covers realistic interest for the poor and reform of current political environment.

Lighting design issues such as quality, quantity, and aiming direction should be carefully considered to select the best suitable type, size, and position of the luminaires under a given space. Lighting designers must also consider a human physiology, psychology, and aesthetic aspects. LEDs which are widely used now, among the various light sources are the best option show various colors and patterns. This paper investigated subject responses of their preferences and associated image on the primary and secondary colors of LEDs and such various patterns.

Outdoor space used for leisure life as inhabitantses" recreation and rest area, and night activity is very important space to many apartment complex. Lately, outdoor space is recognized as a very important space to many apartment complex. Especially, that outdoor space is frequently used at night despite planning of lighting of current outdoor space is unprepared for the selection of suitable luminaires, arrangement of luminaire and lighting plan. From this point of view, this paper investigated the essence of light in outdoor space and analyzed different outdoor luminous environment. This paper finally suggested recommended level of illuminance and planning of lighting.

The recognition of emotionality becomes so important that it is called "emotional consumption society" . The emotional design, which is mostly concerned about user"s consensus and experiences, is understood from a interactive point of view, human, and space. Today, the emotional design is a new paradigm. From this point of view, this paper, which presents patterns analysis of outdoor lighting by the emotional design, applies expression techniques of the emotional design in Analysis process of outdoor lighting patterns. Also, this paper shows examples at analysis process.

광센서 조광제어시스템은 주광을 이용하여 인공조명을 제어하는 대표적인 조명제어시스템이다. 그러나 실내에 설치된 고정된 쉐이딩시스템으로 인해 주광유입을 차단함으로써 광센서 조광제어시스템의 현장 적용성은 낮다. 광센서 조광제어시스템의 적용성 및 정확성의 향상을 위해 자동 롤러쉐이딩시스템과의 통합은 필수적이다. 따라서 본 연구는 롤러쉐이드의 높이에 따른 주광유입분포의 특성을 분석하기 위하여 Mock-up(1/2 스케일) 테스트를 시행하였다. Mock-up은 롤러쉐이드가 설치된 2개의 실과 쉐이딩시스템이 없는 1개의 실로 구성되었다. 롤러쉐이드가 설치된 2개의 실 중 1개소는 롤러쉐이드의 높이를 최하단으로 고정하였고 다른 1개의 실은 태양의 일영각을 기준으로 직사일광의 실내유입깊이를 정하여 산출된 롤러쉐이드의 높이로 제어하였다. Daylight responsive dimming systems are one of lighting control systems which are to control artificial lightings using available daylight for energy savings. This system is not popular because useful daylight is usually blocked by uncontrolled passive shading systems in buildings. It is necessary to integrate daylight responsive dimming systems and automated roller shading systems. In this research, mock-up test is performed to analyze the daylight distributions in three different rooms for integrated systems. Roller shades are installed in two rooms. One is fully downed and the other is controlled by sun profile angle. The other room has no shading system as a reference room.

최근 실내에 유입된 주광을 활용하여 인공조명의 에너지를 절감하는 광센서 조광제어시스템에 관한 연구는 유용한 주광의 유입을 위한 자동 차양장치와의 통합을 중심으로 이루어지고 있다. 기존의 연구는 자동 롤러쉐이딩시스템과 베니션블라이드에 관한 연구로, 이 두 시스템은 주광의 입사를 수직적으로 계산한 일영각을 기준으로 차양장치의 높이 및 각도를 계산하여 제어하고 있다. 본 연구는 광센서 조광제어시스템과 연동을 위한 새로운 차양장치로 주광의 유입을 수직?수평으로 제어하는 복층유리 격자루버시스템을 제안하고, 창면의 위치에 따른 루버의 간격을 산출하였으며, 컴퓨터 시뮬레이션을 통하여 격자루버시스템의 주광유입특성을 분석하고 평가하였다. A recent research trend on the Daylight Responsive Dimming Systems, using available daylight for energy savings, is to integrate automated roller shading systems and venetian blind systems which are vertically controlling daylight to indoor based on sun profile angle. Therefore, this paper suggests Grating Louver System into a pair glass as a new shading system, which can control daylight vertically and horizontally. The optimized spacing of louvers, which is to block direct sunlight into a space, was calculated. And then, the system was simulated for analysis and evaluation of characteristics of daylight by Desktop Radiance 2.0.
