This research aimed to analize the cognitive intensity of valuation(C.I.V) on urban environment as a first stage of the works on evaluative urban image under the hypothesis that it could be interpreted with a correlation analysis between the C.I.V and attitude(Satisfaction of unsatisfaction Intensity) toward urban environment. As a method of a study, 118 cognitive elements were selected representing an urban environment, and each of elements was suggested to citizens of Kyungju with 7 point Likert Scale. The analysis of C.I.V was operated under the three criteria: The first, three of urban space scale(urban scale, neighborhood scale, and housing scale), the second, four elements of urban living environment(safety, amenity, healthfulness, and effectiveness), and the last, thirteen urban unit environment(housing, traffic, education, tourism, medical/health, culture, etc.). The results were as follows: C.I.V to each of 118 elements was cleary defined, showing the possibilities of being applied to a method for subjective, or cognitive evaluation on urban environment: It was revealed that citizens'C.I.V was rather higher in non-physical, qualitative elements than in physical and quantitative ones. This shows well the limitation of the objective method of evaluation of urban environment: The results of the others' studies on the image of Kyungju based on the cognitive approach, being focused on the analysis of the visual aspects of urban structure, cultural assets, historic site and tourism, were almost same as this study but it was quite different for this research to reveal well the citizens' cognition on their living environment of traffic, education, medical, etc..

In order to reduce seismic hazard the characteristics of strong earthquakes are required. In the region where strong earthquakes do not happen frequently the stochastic simulation of strong motion is an alternative way to predict strong motions. this simulation required input parameters such as the quality factor the corner frequency the moment magnitude the stress drop and so on which can be obtained from analyses of records of small and intermediate earthquakes. Using those parameters obtained in the previous work the strong ground motions are predicted employing the stochastic method, . The results are compared to the two observed earthquakes-the Ulsan Offshore Earthquake and the Kyungju Earthquake. Although some deviations are found the predictions are similar to the observed data. Finally we computed attenuation equations for PGA PGV and ground accelerations for some frequencies using the results of predictions. These results can be used for earthquake engineering and more reliable results will come out as earthquake observations continue.

Instrumental observation of earth quakes in KIGAM was first attempted in the earty 1980`s by using 6 portable seismographs in the vicinity of Yang-San Faults. Now twenty-four permanent stations, which are equipped with short-period or broad-band seismometer, are included in seismic research network in KIGAM, including KSRS array station in Wonju which is consisted of 26 bore-hole stations. The seismic network of KIGAM is also linked to that of KEPRI(Korea Electric Power Research Institute)which is consisted of eight stations installed within and around the nuclear power plants. Owing to real-time data acquisition by telemetry, it became feasible to automatically locate hypocenters of the local events within fifteen minutes by computer data processing system, named KEMS(Korea Earthquake Monitoring System). Results of the hypocenter determination, together with observational data, are compiled and stored in the data base system. And they are published via web site whose URL is http://quake.kigam.re.kr KIGAM is also running t재 permanent geomagnetic stations installed in Daejun and Kyungju. The observed geomagnetic data are transmitted to Earthquake Research Centre in KIGAM by seismic network and compiled for the purpose of earthquake prediction research and other basic geophysical research.

The purpose of this study is to examine how Korean changed and applied the railway official residence space constructed by the Japanese, when they occupied these railway official residence space after liberation from Japan, and specify the relationship between the life culture and residence space by analysing the differance in important life style, as well as element of change in important residence spaces according to modernization. In addition, this study was carried out by means of research on the form and pattern, visual anthropological method by photograph and direct observation.The result of this study is summarized as fellows. The residence space at Kyounaju constructed by the Japanese on the basis of the culture has been changed and applied to the life style of the Korean when the Korean occupied these Japanese style residence space.Then, it seems that the change of the Japanese style residence was caused by both differance in the life pattern between Korea and Japan, and the medernization of the life.

This paper presents a precise geoid (PNU95 Geoid) over the southern half of the Korean peninsula. The geoid using the OSU91A reference gravity model to degree and order of 167 with an integration radius of 27 km fits to the well-distributed 71 GPS data best. The RMS difference between the modeled geoid and the GPS/leveling-implied geoid is 0.15 m, and its accuracy with respect to the GPS/leveling distance is 1.1 ppm. The resulting PNU95 Geoid varies from 21.8 m at the western part of the peninsula, Kanghwa-Do, to 30.2 m at the south-eastern part. Kyungju, generally increasing eastward.

This paper presents a design of fuzzy control rules to driving automobile automatically, three types of road are considered, such types are designated as Z-course, S-course, and Hat-course. Fuzzy control rules are designed for each type by combining human experience and engineering sense. Simulation are done for a mixed road containg three types mentioned above. Simulation results show the validity of suggested algorithm.

Recently, information-oriented whole domain and scientific management method for nation-wide territory is widly being used due to the remarkable development such as GIS and RS. In addition to this, request for analyzing forest spatial information has been increasing to manage forest resources efficiently. Although forest information using satellite image and GIS has been built to analyze a large amount of forest information scientifically, there are many difficulties to gather information because normally forest area is large and difficult to access.. This research uses high resolution satellite and digital aerial photograph around Kyungju city area to classify forest area, and stratifies forest area through a spot survey and a comparison of sample area. It will be possible for us to draw a more detailed map of forest area than 1/25000 map of forest area through these works.

The Seongdeok Divine Bell(nicknamed "Emile Bell") represents the bell of the Silla dynasty. However, ringing it was stopped since 2003 for the safety of the bell. Currently, Kyungju city is performing a project casting a new great bell(tentatively named "Great Bell of Silla") that inherits the beautiful appearance and the sound of the Seongdeok Divine Bell in order to ring a new coming millenium. The new bell is designed to be almost same as the Seongdeok Divine Bell in terms of size, weight and shape as well as its sound. In this study, we investigate the problems occurring in the design of the bell structure and propose the design strategy for the reconstruction of the traditional large bells.
