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.

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.

Light has been an essential part of human life. The advancement of technology has changed cities' nightscape and night activities in a drastic way. Lighting has influenced the identity of a city while promoting a variety of civic nighttime cultural pursuits, yet lighting design has not been considered adequately in the field of landscape architecture. This study aims to analyze the current status of lighting in urban parks through interviews with professionals, literature and regulation reviews, analysis of design documents and a field survey focused on Yeouido Park in Seoul. The findings and improvement directions are as follows. First, it is necessary to develop a specific lighting design method in order to avoid a marginalized, passive approach such as light fixture installation. Second, the existing standards of illuminance by KS A 3011 regulating only horizontal illuminance has turned out not to evaluate the current nightscape of urban parks properly. Therefore the criteria and guideline for analysis and design for nightscape should be articulated. Third, there are no design or management strategies to consider the changing landscape of urban parks, which is necessary due to the changing characteristics of park ecosystems. Lastly, detailed guidelines for distinguished spaces in urban parks should be studied and suggested.

Automatic announcement systems and emergency lights are necessary to prevent urban railway vehicles from accident, according to the emergency response guideline of domestic railroad. When emergency situation occurs, safety regulations and standards for urban railway vehicles specify that the emergency lights must be turn-on over 30 minutes as well as that the announcement should be provided by an attendant. However, as the current emergency systems use different units without a standard and system maintenance and management is not well performed, it is difficult to know the operation status. In this paper, modularized structures are given to standardize the emergency systems. The modularized structures analyzed from emergency scenarios of railway can substitute the existing broadcasting and lighting system. As a result, the optimized modular system considering cost and maintenance can be proposed by comparing all modularizations.

This study aimed to analyze a driver's night visibility, according to the installation of a lighting system for driving an agricultural machine during the night time. For the night visibility analysis, a luminance measurement test on the lighting system and a gaze duration measurement test through eye movement measurement devices were carried out. In the luminance measurement test, the increase of luminance was confirmed as relative distance from an agricultural machine was closer and the conditions of the lighting equivalence are improved. Also the gaze duration measurement test, total gaze duration from an agricultural machine increased, as the conditions of the lighting equivalence are improved. In addition, it was identified that the difference in average gaze duration from an agricultural machine was statistically significant as the agricultural machine was driven in high speed. In conclusion, when the lighting system is installed on an agricultural machine, a driver's night visibility from the agricultural machine improves, which is expected to be enormously helpful to the prevention of agricultural machine accidents.

Recently, rapid development of technique and change of lifestyle during nighttime has activated the urban outdoor lighting and renovated consideration of nightscape. As the interest of nightscape increases more widely, outdoor lighting has been installed more and more in the cities. Nightscape comes in diverse forms. So, there is no absolute standard for outdoor lighting. But only bright outdoor lighting is not necessarily a good nightscape. Installation lighting without master plan or excessive outdoor lighting may cause a inharmony. This study aims to analyze the luminous characteristics of facade in shopping complexes. For the purpose, four large-scale shopping complexes located in Dongdaemun area were selected. Building facade composition, outdoor lighting composition, and lighting equipment of each shopping complexes are surveyed, and luminance of building facade were measured with Prometric 1400. The result of the study are as follows; (1) Horizontally large-scale shopping complexes emphasize the building entrance and shape of the building at night by outdoor lighting. (2) Non cut-off luminaries installed in building entrance and shop front caused the potential of light pollution.

Illuminance and luminous levels in a small office space due to daylight were calculated to analyze the impact of daylight on contrast and lighting energy savings. Computer simulations were performed for four blind conditions under a clear sky condition. The blind conditions significantly impacted the illuminance an4 luminance level. Visual performance scores were calculated according to the transfer function that uses absolute contrast between target and background surface. The blind condition that had 45 tilted angle toward ground provided good contrast and performance scores. Using a control algorithm of an automated daylight dimming control system lighting energy sayings were predicted. For all blind conditions minimum lighting energy was consumed.
