최근, 대외적으로 기후변화협약 등 환경에 대한 관심이 높아지면서 국내에서도 온실가스 배출이 큰 에너지의 22.3%를 소비하고 있는 건축물로 인한 환경부하에 관심이 높아지며 고효율 창호의 필요성이 대두되고 있다. 기존의 Low-E (저방사) 유리는 적외선을 반사시켜 단열 유리로서 겨울철에 유리하지만, 건물 전면에 약 50~95% 창호가 사용되는 office 건물에는 여름철 냉방에너지를 많이 사용하기 때문에 단열뿐만 아니라 일사 차폐가 가능한 근적외선 차폐유리가 필요하다. 따라서 본 연구에서는 기존의 Low-E 유리의 문제점인 근적외선 투과문제를 해결하기 위한 기술로서 근적외선 영역을 선택적으로 차폐할 수 있는 박막코팅 물질(흡수체, 반사체) 및 Low-E 대체용 Themochromic 등 나노 박막을 RF magnetron sputtering으로 제조하여 복층유리 구조로 조합해 UV-visible을 측정하였으며 IR Lamp와 태양광 아래에서 온도변화 실험을 진행하였다. 그 결과, 기존 Low-E 복층유리 대비 본 실험에서 사용한 복층유리의 근적외선 차폐효율이 개선됨을 확인하였다.

The concerns on high ozone concentration phenomenon is significantly growing in Seoul metropolitan area including the industry complex area, like Shiwha Banwol area. The aims of this research is the analysis of relationship between high concentrations of $O_3$ and solar radiation parameters in atmosphere. The understanding of the effects of solar radiation intensity, humidity, high air temperature on ozone concentration in a day is very useful to provide a direction for reducing of the high ozone concentration to a local government or a metropolitan government. The correlation analysis between maximum ozone concentration and various meteorological parameters in 2009 - 2011 carried out using IBM's SPSS program. The results showed that the mean correlations coefficient (R) between daily Ozone maximum and solar radiation resulted R = 0.64 during 2011. May - September in 10 air pollution stations. In case of correlations between daily ozone maximum and relative humidity showed negative correlation R = -0.61. The correlation analysis with mean air temperature during 1-3 PM resulted R = 0.29. This low correlation coefficient could be corrected by using of categorized data of ozone concentration. The daily maximum ozone concentration is more dependent on peak solar radiation and high air temperature during 1-3 PM than its simple daily maximum values. The results of this research would be used to develop the high ozone alert system around Seoul metropolitan area. This correlation analysis could be partially integrated to prediction of ozone peak concentration in connection with other methods like classification and regression tree(CART).

A major problem of frequency analysis in the field of low-frequencies such as building or construction vibration is the way of signal processing which is appropriate to obtain included frequency content from the finite process to be measured. Therefore, it is the aim of the investigation reported herein to develop the signal processing algorithm which is analyzed without losing the reliability of the measurements in low-frequency domain. To accomplish the research objective, it was analyzed the problems on the way of signal processing in low-frequency domain, and compared the response characteristics of FFT with those of MEM (Maximum Entropy Method) about the low-frequency of vibration. This evaluation of the response characteristics is used in determining appropriate signal processing algorithm into the low-frequency domain.

Use of concrete has undoubtedly become widespread in construction and civil engineering. Sensors are used to add functional characteristics to concrete. Self-diagnosis concrete is also being developed. The thermal protector used in the study is a sensor using the linear expansion and cubical expansion of metal. The LED(Light Emitting Diode) is a phototransistor type, and to secure high-sensitivity light, the prices of these sensors are low. Rising temperatures of concrete elements can be predicted from LED of the external virtual beam due to operation of thermal protector sensors of concrete beam caused by fire load on the concrete specimen. In this study, the development of fire-diagnosis concrete using composite sensors are the fundamental study for damage detection using simply measurements.

Public environment including urban circumstances has taken on importance in that it could be nation's cultural powers latent these days. Also, today's study on the field of environment design so far has mainly focused on the fields of architecture and urban panning, while its consideration as the complex of various cultural factors is not enough yet. In addition, because study on the urban super graphic which greatly servos as communication between people and environment is not enough, super graphic has not arose enough public response in reality. The purpose of this thesis is to make super graphic revitalize as the meads of communication from the viewpoint of art, information arid aesthetics by looking into relationship between super graphic and contemporary art motivated in developing process. And This thesis is made studied relationship between super graphic and contemporary art divided into modernism art and post-modernism art.
