This study tried to inquire architectural tendencies in public art projects by analyzing projects and public art works designed by Korean architects. First, it described not only the background and the objectives of this study but also the scope and the methods of it. Second, it gave an overview of public art by explaining the concept, the institutions, and the history of it in Korea. Third, it investigated the contents of public art projects in Korea, in which more than two architectural teams participated, analyzing the tendencies of public art works designed by architects. In order to find the architectural tendencies of public art projects, it analyzed the intentions, the contents and the expressions of architects' art works. In conclusion, this study regarded the architectural tendencies as site-specific, space-experiencing, sheltering, multi-purposeful, contextual, recycling, and eco-friendly.

One of the big difference between Aalto and other modem architects lies in an attitude that Aalto went beyond the principle of dogmatic functionalism. As an architect of Northern Europe, Aalto made unique architecture that showed both the language of modem architecture and vernacular architecture. He presented the best example which showed modernity in architecture without losing the meaning of the context including site, region and cultural tradition. With this background, Aalto developed his own typological design approach. As Wolfsburg church was designed in his prime of time, it showed the origin and evolutionary process of religious architecture as well as general features of Aalto's design. Clustered site plan, dynamic space of interior, the adequate control of natural light are representative characteristics found in Aalto's religious architecture. Wolfsburg church also demonstrate these features in more specific way including the continuity of wall and ceiling that showed spatial dynamics, free opening of wall which reflects on functions, and careful adjust of natural light. As a result, Aalto showed his typological design strategy that added new design ideas to the accumulated design vocabularies in the design of Wolfsburg church.

On-site diagnosis of chiller performance is an essential step fur energy saving business. The main purpose of the on-site diagnosis is to predict the COP of a target chiller. Many models based on thermodynamics background have been proposed for this purpose. However, they have to be modified from chiller to chiller and require deep insight into thermodynamics that most of field engineers are often lacking in. This study focuses on developing an easy-to-use diagnostic technique that is based on adaptive neuro-fuzzy inference system (ANFIS). Quality of the training data for ANFIS, sampled over June through September, is assessed by checking COP prediction errors. The architecture of the ANFIS, its error bounds, and collection of training data are described in detail.

The background noise and transmission loss of wall were measured on site for the multiplex cinema. The results from the simulation analysis was compared with the measurements from the site for different frequencies to review the acoustical parameters, and the analysis results in the relatively small error. Therefore, it is concluded that the reliable estimation can be made once accurate data such as sound source and sound absorption coefficient of interior material is utilized during the simulation process. However, the calibration is necessary for the test room with the small room volume.

This study was purposed to explore how the information society effects on the working life of the married women. To answer the question, with theroetical background, 6 married women's cases which were selected through women's portal internet site were analysed. As results, these married women had contracting base, part-time jobs. Their jobs were chacterized by computerizing. They were different with traditional jobs in the industrial society. Internet sites were effectively used for work information network by them. So, in the future, many married women will be able to find working opportunity in a home-based part-time job through internet. And they presented aptitude for their work. Her children and husband were proud of her. They had confidence in their working ability Many women had a project publishing a book, owning a business, and making new products by her own's idea.

Gyeongbokgungdo depicts the composition and layout of Gyeongbokgung Palace before the Japanese Invasion of Korea in 1592, as well as a monument related to pro-jamrye held at the site of Gyeongbokgung Palace in Yeongjo. Based on literature such as Dongguk Yeoji Seungram, such as Gyeongbokgungdo painted major buildings, government offices, and buildings in the backyard. In addition, the literature and the foot of the mountain, waterway, and Pond, which were identified as the site identified during the reconstruction process, are reflected, and some of the Gyeongbokgungdo contain reconstruction records. As such, Gyeongbokgungdo depicts Gyeongbokgung Palace in the early Joseon Dynasty and facilities built after the Imjin War based on the literature, and seems to have been produced around the time of reconstruction as it reflects the mountain and water system. In addition, the layout of the main hall of Gyeongbokgungdo was partially reflected in the reconstructed Gyeongbokgung Palace and used as a material to understand the layout of Gyeongbokgung Palace in the early Joseon Dynasty.

Sampling of precipitation occurred at Woongchon in Choongnam from the period between May 1994 and April 1995 was made, and analysis on the data was carried out on observed pH values of the precipitations. It was found that weighted mean pH values were .sim. 4.8 and that acid rain occurred at the site of the Yellow Sea's coastal area. The results agree well with the earlier observations made at other sites of a background monitoring network. The annual values observed at the background monitoring sites were too low in comparison with the mean pH values (5.3 .sim. 5.9) obtained from urban stations of the Ministry of Environment. It was observed that values of pH in rain water often changed with time during the event of precipitation, and the low values usually depended on an airflow and a cyclone that originated in the source region.

Acoustic emission technology is applied to diagnosis the internal leak and operating conditions of the major valves at nuclear power plants. The purpose of this study is to verify availability of the acoustic emission as in-situ diagnosis method. In this study, acoustic emission tests are performed when the pressurized high temperature steam flowed through gate valve(1st stage reheater valve) and glove valve(main steam dump valve) on the normal size of 4 and 8". The valve internal leak diagnosis system for practical field was designed. The acoustic emission method was applied to the valves at the site, and the background noise was measured for the abnormal plant condition. To improve the reliability, a judgment of leak on the system was used various factors which are AE parameters, trend analysis, signal level analysis and RMS(root mean square) analysis of acoustic signal emitted from the valve operating condition internal leak.

Background: Not only regulatory framework including radiation protection quantities and regulatory standards, but also methodology for regulatory compliance may be different in each country due to inherent philosophy for radiation protection. Materials and Methods: Based on the Korean regulatory models, off-site radiological dose resulting from the routine releases of gaseous radioactive effluents was calculated by applying the parameter values and assumptions recommended in the Korean and Japanese regulations. Results and Discussion: Effective dose for adult based on the Korean recommendation were 17.5 and 1.6 times higher than those of Japanese recommendation for ¹³¹I and ¹³³I, respectively, for the same atmosphere dispersion and ground deposition factors. Conclusion: It was due to different parameter values and assumptions recommended for the purpose of evaluating compliance with dose criteria for the radiation protection of the public in each country.
