Outdoor lighting is an important factor of the urban scape. As a night image of the city, outdoor lighting acts important roles. Cities of developed countries have already had there own night images. Regarding this, government encourages outdoor lighting of building by various ways to building owners. However, in present, owners of private buildings have not been up and coming about outdoor lighting more than those of public buildings in our country. From this point of view, this paper suggests a quantification method for economic effects of outdoor lighting and analyzes economic effects of outdoor lighting in advertising. A suggested measurement method of economic effects is difficult to measure all economic effects of outdoor lighting. Therefore, this measurement method limits the target to the private buildings.

Outdoor lighting is an important factor of urban scape. As a night image of the city, outdoor lighting acts important roles. Cities of developed countries have already had night images of their cites. About this, government is encouraging outdoor lighting of building by various ways. However, in present, outdoor lighting of headquarter buildings was not activated more than that of public buildings in our country. From this point of view, this paper presents a method to measure outdoor lighting effects as quantitative aspects for outdoor lighting activation. Presented the method of outdoor lighting effects is difficult to apply all buildings. Therefore, this paper limits the target to the headquarter buildings.

Purpose : The purpose of this study was to investigate the effects of music intervention upon lighting on stress. Method : The participants 60 college students, were divided three groups. Two groups were apply each music and bright lighting(bright lighting groups) and music and dark lighting(dark lighting groups) during 13minutes at Snozelen and the other group was control group. Each groups were assessed stress resistance, activity of parasympathetic nerve, activity of sympathetic nerve, balance of ANS, physical arousal by EKG of CANS 3000, at before and after other each intervention. The analyses were performed using version of SPSS 17. Result : The change rate of bright lighting group was showed statistically significant decrease in stress resistance compared to control group. And the change rate of dark lighting group was showed statistically significant decrease in resistance stress, activity of parasympathetic nerve, and balance of ANS compared to control group and statistically significant increase in stress resistance and activity of parasympathetic nerve compared to bright lighting group. Conclusion : The results of this study indicate that music intervention on dark lighting is more effective on decrease of stress than application of bright lighting and general lighting.

Purpose: This study was aimed at finding the effects of cycled lighting on body weight, physiological variables and the behavioral state of LBWI (low birth weight infants) in the NICU. Method: The subjects were 20 LBWI at 2 NICUs. They were assigned to an experimental or control group which consisted of 10 subjects in each. Cycled light was applied to the experimental group for 10 days. Result: It was certified that the application of cycled lighting resulted in increased body weight and O2 saturation, and decreased heart rate of the LBWI. However, there was no effect in decrease of respiration and stabilization of the behavioral state. Conclusion: The application of cycled lighting might be a nursing intervention which would in turn have positive effects on the growth of LBWI.

Stage lighting plays a significant role in drawing out the mood and images that are intended by the choreographer. It is related to the dancers' movements and affects them both directly and indirectly. This study is on a reciprocal relationship between dance choreography and stage lighting, covering a broad range of functional factors of lighting effects on the dance choreography. Also, the data on preferred lighting colours and their frequency of usage are gathered through surveys by lighting specialists. The data is used to identify the lighting colour in general dance choreography. It is collected to serve the purpose of providing opportunities to acknowledge the needs of various colour changes on the stage. It is hoped that a collaboration of studies related in this subject are continuously promoted and researched in producing high quality dance performances.

Although it has been suggested that lighting influences our moods, little is known about dimensionality of mood patterns. The knowledge of consumer's mood pattern in lighting condition may provide interior designers with a valuable information for the lighting design. This article investigates the underlying structure of moods occuring in lighting conditions. Meanwhile, this examines custom-ers' desired mood type of lighting, and explores the influ-ence of individual characteristics on selecting the preffered lighting moods. The result uncovers five discriminable patterns of mood-dynamic, intimate, delightful, elegant, and serene feeling results from well organized lighting system. Among the five moods, serene atmosphere appears to be the most preffered mood from respondants. It is also found that the perceived preference of lighting atmo-sphere varies across personal characteristics of the cus-tomers, socio-economic differences and the visiting pur-poses to the coffeeshop. These findings present interest-ing and potentially valuable implications for interior de-signers that proper planning of lights which inducemoods can achieve dramatic effects and aid in the cre-ation of the desired atmosphere.

Artificial lighting accounts for a significant portion of the energy use in office buildings. Therefore, daylighting is considered one of the fundamental design features of energy-efficient buildings. However, complex daylighting simulation tools are not suitable for most designers to help in the decision-making process. This paper provides the results of a simulation analysis to determine the potential energy savings of daylighting effects reducing electrical energy consumption for office building. A whole building simulation tool is used to determine the effects of daylighting on lighting electricity use as well as total electricity use for typical office buildings. It was determined that daylighting does not provide significant additional lighting energy savings when glass transmittance is increased over 0.7 A simplified method is developed based on the analysis results to estimate the annual electrical energy savings attributed to daylighting.

A performance delivers the contents and feeling through human bodies and stage settings in the limited space of a stage. Among the stage settings, the lighting creates overall atmospheres effectively according to the situations of the performance such as a time flow, a change of seasons, an expression of the mental state of the performer. As the LED lighting is used more widely, the number and the size of the lighting is being decreased, which makes it possible for various devices to be used. However, just as conventional lighting devices, most of them are fixed. So it is difficult to use them at a blind spot and to replace them. To solve this problem, this article suggests a system which replaces lighting automatically and moves. As it can moved to a spot we want on a rail, and the lighting system can be replaced by itself, it can have various lighting effects, increasing the effectiveness of the performance. Additionally, it can also decrease the danger of a worker operating the lighting device located at a high place. At the mock-up experiment, its mobility and stability on a rail were tested using the wheel of the Modular Robot.

The outdoor lighting is provided for a variety of purposes, for work or recreation, for safety or security, for amenity and for advertising or display. But the effects of lighting on the natural environment can be difficult to quantify. At present, in many countries, various policies to manage the light trespass from outdoor light have been planned. For example, Model Lighting Ordinance(MLO) will allow communities to drastically reduce light pollution and glare and lower excessive light levels. The recommended practices of the IES can be met using readily available, reasonably priced lighting equipment. So, it this paper, we analyze the effect of road lighting on light trespass using by RELUX program. And then we consider the possibility of practical application of BUG rating in Korea.
