This research surveys actual conditions in order to examine the lighting environments of the elderly's residential 50 households. The results is as following. First, The elderly indicated that they felt the living room and the kitchen are usual degree, dark only in bedrooms and rest rooms of brightness. And about satisfactory degree of residential illumination is being above of usual Satisfaction. Second, Problems of lighting environments of elderly's houses were brightness and management, when lighting environmental reconstruct, considered brightness and equipment superannuation, and they want the focus on brightness in the reconstruction. Third. Operating method of lighting was used almost overall lighting in bedroom and bathroom, overall lighting and part lighting are used together in kitchens. The living room has a lot of cases which uses only a general illumination, but the cases which overall lighting and part lighting are used together has occupied 40[%]. Fourth, An average Illuminance of the bedroom is 104.17[lx], an average unifonnity ratio is 60.22[%]. The livingroom's average is 116.15[lx], 51.48[%]. The sink's average is 236.40[lx], the table average is 160.73[lx] in the kitchen. The washstand's average is 109.81[lx], the chamber's average pot is 74.33[lx] in the bathroom. These results are generally darker than the standard.

인터넷 플라자에서 있어 실내 조명은 이용자들의 시력보호측면에서 중요한 사항이나 적정 조명에 관한 제안치가 없으며 PC방은 국내의 여러 가지 여건이나 정부정책에 따라 우후죽순으로 확대 설치된 것으로 청소년의 좋지 않은 온상으로 비난받고 있는 것으로 보도되고 있다.(중략)

This paper investigates the illuminance level at the existing gas statioos and compares the results with the KS and IESNA standards. The IreaSured illuminance level in the pump island area is found to be high up to 3 tirres the recorrnrended value in KS and sorrewhat lower than one in IESNA standard. From this result we coodude that significant degree of energy saving can be possible from prwer maintenance program, and careful coosideration must be paid in the design process. And the KS standard need to be examined more thoroughly against other nation's standards.

This study investigated the actual conditions of the illumination environment from agricultural youth study room. The result, average space of the study room was 11.42[$m^2$]. The illuminant uses the fluorescent lamp mainly, Method of using illumination was only general illumination the case which uses 73.8[%]. Method of light distribution was a direct lighting mainly. The house which has a stand illumination was also 45.7[%], The percentage using the stand illumination which was a local illumination was nothing but in 20[%] of the whole subject of investigation, therefore eye work could not effective. The internal illuminance was average 131.82[lx], the desk illuminance was 253.64[lx] which was the minimum permitted limit and poor. Uniformity ratio of illuminance appeared with average 35.61[%]. The satisfaction with 3.93 points to be high for illumination environment, therefore it was thought that the recognition of illumination was very insufficient.
