Many business enterprises in domestic housing industry are focusing on the development of environment friendly apartment complex to strengthen the competitiveness by upgrading their company's image through differentiation of the qualities and satisfying the customer's needs. Many apartment complex have achieved temporary or real certification by green building certification system, but there weren't enough studies on how much residents are satisfied by their certified complex. In this study, we want to clarify the factors of resident's satisfaction level in certified environment friendly complex by comparing the social and economical characteristics of resident. For this study, we chose and compare 4 environment friendly apartment complex considered to be built by the best environmental way in metropolitan area, and 4 other apartment complex which are also considered to be similar in terms of the condition of location and period of stay.

The purposes of this study was to collect, analyze, and describe the MF exposure levels from subways in Korea and to measure and evaluate the MF levels generated from electric appliances used at general homes. The target subway lines were Seoul Metropolitan Line 1 to Line 8, Bundang Line, Incheon Line, Daegu Line, Gwangju Line, and Busan Line 1 and Line 2. We measured at each station in those subway lines and, all the train types (pantograph-equipped, motor-equipped, and common), and platform types(facing and isolating) were investigated by the distance(80, 200, 400 cm) from the train on 19 targeted subway lines using 3 magnetic field measuring devices (EMDEX Ⅱ, Enertech Co.) during the survey from January till October, 2004. On the other hand, the levels of the 60Hz magnetic fields generated from 14 items of home electric appliances such as electric blankets, hair dryers, electric razors, etc. were measured at 10 general homes using 5 EMDEX Ⅱ meters with a sampling interval of 1.5 second by the distance(surface, 30, 50, 100, 300 cm) from the target electric appliances. The survey results in the whole subway lines examined in this study were as follows; Seoul Metropolitan Line 4 using AC(alternating current) power source showed the highest mean value of 2.85 μT, followed by Seoul Metropolitan Line 1 running between Seoul and Incheon using AC(2.78 μT), Seoul Metropolitan Line 1 between Seoul and Uijongbu using AC(2.73 μT), Bundang Line using AC(1.79 μT), Seoul Metropolitan Line 1 connected from Yongsan using AC(1.67 μT), Seoul Metropolitan Line 1 between Seoul and Suwon using AC(0.79 μT), and so on. In general, the intensity of the magnetic field in the subway systems in Korea was significantly higher when using AC(2.14±0.91 μT) than when using DC(0.29±0.44 μT) power source. Among the home electric appliances examined, microwave ovens showed the highest mean value of 7.69 μT, followed by hair dryers(6.47 μT), vacuum cleaners(5.27 μT), televisions (2.26 μT), electric blankets(1.38 μT), personal computers (0.81 μT), and so on. Two items of electric appliances showed the excess value of 0.2 μT at the distance of 30cm in the MF exposure level; electric razors 1.58±2.13 μT and vacuum cleaners 0.48±0.44 μT. As a whole, this study showed a tendency that the shift of the MF levels according to the increase of distance from the electric appliances was lower than those of the results surveyed in UK and USA. As a result, this study is expected to suggest meaningful data for the future study in exposure assessment of magnetic fields and for the establishment of guidelines for subways and electric appliances in Korea. More detailed and large scaled exposure assessment studies should be performed continuously to get the various and useful information on health risk assessment of MFs in Korea.

The rapid growth of camera technology can provide various types of information which was not previously provided. Furthermore, IP camera which has rapid data transfer rate and high resolution particularly provide a lot of useful functions beyond the existing simple surveillance capabilities. We are developing Real-Time Face Recognition Access Control System based on the camera technology, and improvement of face detection and recognition algorithms are vitally needed to realize that system. In this paper, we proposes a method to improve the computing speed and detection rate by adding new features to the existing Viola-Jones detection algorithm.
