AZO(Aluminum-doped Zinc Oxide) films are attractive materials as transparent conductive electrode because they are inexpensive, nontoxic and abundant element compared with ITO(Indium Tin Oxide). AZO films have been deposited on glass (corning 1737) substrates by RF magnetron sputtering. The AZO film was post-annealed at $600^{\circ}C$ for 2 hr with $N_2$ atmosphere. The AZO films were used as an anode contact to fabricate OLEDs(Organic Light Emitting Diodes). OLEDs with $AZO/TPD/Alq_3/Al$ configuration were fabricated by thermal evaporation. We investigated that the electric, structural and optical properties of AZO thin films, which measured using the methods of XRD, SEM, Hall measurement and Spectrophotometer. The current density-voltage and luminescence-voltage properties of devices were studied and compared with ITO devices fabricated under the same conditions.

우리나라의 범죄발생 현황을 분석하면 생명, 재산과 관련된 흉악범죄의 증가 추이가 두드러진다. 이러한 사회 현황에 대한 경각심과 국민들의 안전욕구 강화에 따라, 정부차원의 다양한 방안이 시도되고 있다. 그러나, 세부적인 환경디자인요소에 대한 구체적인 방안은 미흡한 것이 현실이다. 따라서, 본 연구는 도시의 범죄율이 높은 공간 중 대표적인 공간유형인 폐쇄적인 골목길을 선정하여, 환경디자인 구성요소들의 효용성과 개선방향에 대하여 조사ㆍ분석하여, CPTED 기법의 개선방향을 제시하였다. 1) 문헌을 통해 CPTED의 개요 및 구성 원리에 대해 조사 분석 하고, 2) CPTED기법으로 활용되고 있는 환경요소들을 도출하였다. 3) KJ법을 활용하여, 폐쇄적 공간에서 환경 요소에 대한 CPTED기법의 적정성 여부, 문제점, 개선방향 등을 분석하였다. 4) 최종적으로는, 폐쇄적 공간에 적합한 환경요소를 파악하고, 이에 대하여 CPTED기법을 적용하기 위한 방향을 제시하였다. 분석 결과 크게 2가지로 정리하면 다음과 같다. 1) 폐쇄된 골목길에서 가장 필요로 하는 환경요소는 가로등이며, 실제 CPTED요소로서 이러한 공간에 많이 사용되는 미러거울이나 코너볼록거울은 부정적으로 생각하는 경향이 많은 것으로 나타났다. 이들은 다른 요소와 결합하여 사용하므로, 각각의 단점을 최소화하고 활용도를 높이는 방안으로 강구해야 한다. 2) 기계적 요소 중 CCTV, 위치번호판, SOS비상벨의 색상은 고채도의 색채를 사용하거나 조명과 병행하여 사용하므로 시인성과 유목성을 높이도록 계획하여야 하며, 벽화와 울타리에 대해서는 효과적인 디자인에 대한 고려가 반드시 필요하다. 향후 다양한 특성의 공간에 적합한 환경시설물에 대한 조사와 그에 따른 디자인에 대한 연구가 필요하다. According to the crime statistics in South Korea, the number of serious crime which is related to individual life and property has been increased. Due to the fact that arousing people’s attention to the security issue is not able to overlook so that there are a lot of approaches to deal with alleviating the crime rate by Korea government. However, the specific solution for environmental design factor in detail had not been presented. Accordingly, this research is working on analyzing the usefulness and improvement of the CPTED method in environmental design factor as well as the research method is going to apply to the narrow back streets which are related to the high crime rate. 1) Literature reviews account for the basic knowledge of the CPTED 2) Evaluating environmental factor based on the CPTED method. 3) Analysed possible development, problem, reasonableness of CPTED method in regards to environmental component in closed space by applying KJ method. 4) Finally, analysed appropriate environmental factor for closed space and provided guideline in order to apply the CPTED method. Result can be stated in 2 points as follows, 1) It appears that the most needed environmental factor on a closed alley is a streetlight, while mirrors or corner convex mirrors, the most commonly used CPTED factors in alleys, are perceived negatively. Since these factors are used in combination with others, the solution to diminish weaknesses and enhance efficiency must be considered. 2) Of mechanical factors, CCTV’s, location number plates, and SOS emergency bells have to be in high chroma or utilized with lightings, so they have to be planned to heighten attractiveness of colors and ability to be observed. Effective designs of installation on walls or fences must be considered. Research on environmental equipment appropriate for certain places and research on design accordingly must be accompanied.

The PV application into buildings is regarded as an important element for sustainable zero energy buildings that require energy generation through renewable energy systems such as photovoltaics. However the appearance of building-integrated PV(BIPV) is not always pleasing, as some people see them as a machinelike high-tech image. This aspect may deter architects and designers to take this relatively new technology into account when designing their projects. The aim of this study is to establish a practical guide for color design in house exterior that is applied with PV module. The parameters of this experiment were the color of PV module and the hue and the tone of exterior wall. Factor analysis and multiple-regression analysis(HAYASI I) were carried out basically for the reliability of visual effects. As a results of factor analysis, three factors were extracted. Factor Ⅰ related to 'evaluation' Factor and composed of 'Desirable', 'Comfortable', etc. Factor Ⅱ related to 'Activity' Factor and composed of 'Fresh', 'Bright', etc. Factor Ⅲ related to 'Warm' Factor and composed of 'Warm', 'Soft', etc. As a result of HAYASI I analysis, the hue of exterior was mainly effected on evaluation.

The transparent conductive oxide(TCO) has been used in necessity as front electrode for increasing efficiency of LED. In our paper, aluminium-doped zinc oxide films(AZO), which has transparent conducting were prepared with RF magnetron sputtering system on glass substrate(corning 1737) and annealed at $400^{\circ}C$ for 2 hr in vacuum ambient and $600^{\circ}C$ for 2hr with $O_2$ ambient respectively. The smooth AZO films were etched in diluted HCL(0.5 %) to examine the surface properties, which in ambient post-annealing process. We confirmed that the electric, structural and optical properties of textured AZO thin films, which implemented using the methods of XRD, FWHM, AFM and Hall measurement. The properties of textured AZO thin films especially depended on the ambient post-annealing process. We presumed that the change of transmittances as R G B LED and the ambient post-annealing process will be increasing the efficiency of LED.
