Korean representative residence type is apartment house. Due to this, civil complaint related to living noise is rapidly increasing. Here, in case when they suffer from surrounding noise in daily life, they can raise civil complaint. However, in general home, it is difficult to measure noise utilizing expert equipment, in many cases they use smart phone app. Noise measurement app that was previously released has markedly low correctness, e.g. value is differently measured in the same condition, therefore, it is difficult to be used for the actual noise measurement. Therefore, this paper suggests mobile data process system for noise measurement of living environment utilizing smart phone. The expected effect of this research can be utilized as the civil complaint material by conveniently measuring the noise and presuming the direction that the noise appeared at the home that has no equipment.

최근 우리나라에서는 대형 화재사고가 빈번히 발생함에 따라 그로 인한 재산 및 인명피해가 날로 증가하고 있는 실정이다. 따라서 건축물 내에서 화재가 발생할 경우 인명피해를 최소화하기 위하여 피난유도설비의 설치를 의무화하고 있다. 지금까지 일반적으로 가장 널리 사용되고 있는 피난유도설비로는 유도등이 있으며, 최근 들어 피난유도선의 설치도 다중이용업소를 중심으로 점차 확대되어가고 있는 추세이다. 피난유도설비는 평상시 이용되는 교류 상용전원에 의해서뿐만 아니라 비상시 이용되는 직류 비상전원에 의해서도 정상적으로 작동되어야 하기 때문에, 피난유도설비의 전원장치는 주어진 전원으로부터 주어지는 교류 또는 직류를 발광부에 맞게 일정한 전압과 주파수로 변환시켜주어야 한다. 실제로 LED(발광다이오드) 유도등은 상용전원으로부터 220V의 교류를 받아서 전원장치에서 정류변환을 통해 얻어지는 낮은 전압 24V의 직류를 이용하며, 대부분의 유도등 백라이트로 사용되고 있는 CCFL(냉음극형광램프)에는 상용전원으로부터 220V, 60Hz 교류를 인가받아 전원장치에서 정류 역변환을 통해 만들어진 100kHz의 고주파 교류가 공급된다. 더욱이 유도선의 전원장치에서는 상용전원 220V, 60Hz의 교류를 인가받아 정류 역변환 및 교류변환 과정을 차례로 거쳐 최종적으로 100V, 400Hz의 교류로 전환하여 TFEL(박막전계발광) 소자로 전송하게 된다. 한편, 상용전원이 차단된 상태에서도 전원장치는 마찬가지로 비상전원으로부터 24V의 직류를 공급받아 인버터를 통해 역변환 하여 100kHz의 고주파 교류를 만들어 주거나 추가적인 교류변환을 거쳐 100V, 400Hz의 교류로 변환시켜 내보낸다. 본 연구에서는 상대적으로 복잡한 전력변환 회로들을 포함하고 있는 유도선의 전원장치를 개선하여, 전원장치의 연결가능길이를 기존의 60m에서 최대 100m까지 연장시킴으로써, 터널이나 지하도와 같은 곳에서 특히 경쟁력을 갖게 될 것으로 기대된다.

Due to recent urban maintenance project for the aged towns, the reconstruction of apartments into super-high-rise and high-rise apartment structures has been approved for concentrated use of land, and accordingly the infringement on sunshine for nearby residential area is rising as a social issue. Especially the educational environment conditions according to infringement on sunshine in educational facilities are posing many problems. Accordingly in this study, for such sunshine analysis of educational environment, Auto $CAD^{(R)}$ software has been used to construct the 3D model for the educational facility structures. And with the simulation technique, the windows and the schoolyard of the education facility were set to be the lighting standard surface to take measurements for the sunshine environment of the educational facilities by the minute from 8:00AM until 4:00PM for the sunshine amount by true solar time according to the movement of the sun. Also, the sunshine environment of the education facility according to the damage before/after new construction of apartments was charted, and through comparison with the video produced by sun shadow projection method, the sunshine amount of the educational environment could be verified. In future, it is expected to be efficiently used in the sunshine analysis of education environment utilizing such simulation techniques.

The land use has been changed artificially and caused the result of temperature increase of city compared with the outside of city or region of park and forest. The purpose of this research is to analyze the change of the urban surface temperature with land use zoning in Jinju using Landsat TM/$ETM^+$ imagery and to provide the correlation between NDVI(Normalized Difference Vegetation Index) and urban surface temperature change. The results presented that the spatial distribution of urban surface temperature was depending on the change of NDVI values on land use zoning. Considering to the average temperature by land use zoning, industrial area was the highest temperature but green area was the lowest temperature. Also as a result of comparing the correlation between surface temperature and NDVI, the green and residential area had higher correlation values than the commercial and industrial area. These results will be played a part as one of the major factors for implementing the sustainable urban planning considering the urban heat island effect problem.
