The $M_w=5.8$ Kyungju (South Korea) earthquake took place on 12 September 2016. This event may cause deformation around Kyungju city, located in the southeastern part of the Korean peninsula. In this study, GPS data was collected from the 17 Korean CORS and processed to determine the deformation. Minimum constraint solutions, to avoid the network distortion, are obtained and an S-transformation is applied to the coordinate difference vector and its covariance matrix for comparisons. In the final step, a statistical test is performed to determine the deformation due to the Kyungju earthquake. Based on the results, it was found that there is no significant deformation around Kyungju city. Hence, it can be said that the re-measurement or re-establishment of the geodetic control points in South Korea is not required.

This paper discusses the change of land ownership in the urban historical core of Kyungju city in the Period of Japanese occupancy(1910-45) based on the analysis of land register records. Kyungju city was not designated for the cities controlled by urban planning law which was set up in 1912 and 1934. The major purpose of this paper is to clarify the urbanization process of a Korean local city where the formal urban planning projects were not carried out. The focus of the study is the increase of the Japanese landowners and Japanization of the landscape. In the very beginning of occupation, Japanese already owned about 8% of the total land of the city centre where the old Kyungju castle had been located. The ratio of the land owned by Japanese went up to more or less 70% at the end of World war II. The process which the urban core had been replaced for the Japanese is very clearly traced from the analysis of a land register records.

The purpose of this study is to interpret the townscape of Kyungju based on the urban images captured by citizens. 58 verval interviews and 50 sketch maps were collected and analized comparing with York which was a similar old city in England. In the verbal questions, elements like tombs, historic remains, families and historic values were frequently mentioned mainly because of their social and historic meaning. But in the sketch maps, physical elements like railroad station, city hall, roundabouts and streets were more frequently appeared probably because of their visibility. As a whole, many tombs which were built long ago in and around the city were commonly mentioned in verbal questions, sketch maps and even in nicknames. As the most dominant factors, it can be compared with York Minster in York. But whereas the shopping streets in York were very attractive to the people, many streets in Kyungju were regarded as dirty and inharmonious elements in townscape. In conclusion, we can call Kyungju 'the city of tombs', but to evoke the sense of place in the city the streets should be improved and activated as the center of city life.

A well-bucket excavated from Seobu-dong, Kyungju was characterized and conserved. The bucket was heavily degraded by a diverse set of microorganisms during its long-term storage in the burial site. The distribution of maximum saturated moisture content was in the range of 614-1050%. The identification of species using optical microscope showed that the species was Pinus densiflora. The dimensional stability of the bucket was examined using sucrose as a dimension-stabilizing agent. The concentration of sucrose was started at 10% level and raised to 30, 50, 70% for 8 weeks. The changes of weight increase were varied with concentration. When the concentration of sucrose reached to 30%, 50%, the bucket showed the significant increase of weight, especially. Epoxy adhesives was used for the joining and restoring. Dimensional change and crack were not observed afterward.

The abundance and local distribution of birds around the three atomic power plants were studied during summer in 1998 and winter 1989. It was particularly pointed out how to determine species diversity indices, rarefaction model appeared and habitat use. During the study over 2,200 birds were censused; black-tailed gull, terek sandpipper, asian wandering tattler and australian curlew accountedfor over 76% of the observed birds in summer. Black-tailed gull, black-headed gull, mallard, ancient murrelet and tree sparrow accounted for 76% of the observed birds in winter. overall, 53 species were occurred ; 23 have been observed on yonggwang-gun, 16 used on ulchin-gun, 12 used on kyungju-gun in summer. 18 on yonggwang-gun,,14 on ulchin-gun,12 on kyungju-gun in winter respectively. These three habitats in terms of their of species richness were computed as follows; yonggwang-gun has the highest richness with an expected species number of 17.5 as the same as two season. Kyungju-gun has the lowest with an expected species number of 8.2 in summer and 11.5 in winter.

Investigations were performed on the flora, community composition and ecology of the diatoms collected from the water system in the suburbs of Kyungju city from June, 1981 to May, 1982 and from August to September, 1983. Total taxa of 157 were identified as diatoms consisting of 2 orders, 5 suborders, 8 families, 12 subfamilies, 26 genera, 97 species, 54 varieties and 6 forma. Among them 69 taxa were found as unreported ones in Korea. By the creteria of adaptability of these taxa to organic pollution in water, the taxa could classified as 8 of tolerant, 34 of indifferent and 115 of intolerant taxa.

This study aimed at reconstruction the forgotten rules of Silla's. Bulguksa and Sokgulam in their conditions of location and spatial orders. So tried to find out what Korean Traditional principles in spatial art were and how they actually worked. The locations of these two temples related to their immediate environments, the geometric cityscape of the old city Kyungju. This geometric figure formed the basic of city master plan in the 8the century. And it highly effected on not these two temples but also many other significant places in locating decision making.

This study analyzed the relationship between NDVI(Normalized Difference Vegetation Index) and urban heat island in three cities: Daegu, Kyungju, and Pohang for understanding the degree of nature conservation concentrating in the transition zone of them. Daegu city is the third city in Korea which has a dense population. Kyungju is a traditional city which has good nature. Pohang is an industrial city which has those of characters of Daegu and Kyungju. Landsat 1M data in May 17, 1997 were used for the analysis of heat island. There were about four theoretical models to estimate the surface temperature from TM data: Two-point linear model, Linear regression model, Quadratic regression model, and Cubic regression model. In this study, Linear regression model had been utilized to analyze the urban heat island. On the resultant images, the transition zone of Daegu was urbanized more extremely than those of other two cities. It is thought that the analysis of relationship between NDVI and surface temperature, used in this study, is regarded as one of effective methodologies for urban-environmental detection from satellite imageries.

The mutagenicities and antimutagenicities of butanol (PL I) and water (PL II) extracts from the filtrate of the cultured broth of Phellinus linteus were examined using the Ames/Salmonella test. No mutagenic activity of PL I and PL II was found in Salmonella typhimurium strains TA98 and TA100, either with or without S9 activation. In contrast, PL I and PL II showed inhibitory effects on the mutagenic activities induced by the directly-acting mutagens, 4-nitro-o-phenylenediamine (NPD) using the tester strain TA98 and sodium azide (NaN3) using the tester strain TA 100 in the absence of S9 mix. PLI and PL II also showed inhibitory effects on the mutagenicities of the indirectly-acting mutagens, 2-aminofluorene (2-AF) using the tester strain TA98 and benzo[a]pyrene (B[a]P) using the tester strain TA 100 in the presence of S9. These results suggest that P. linteus has an antimutagenic activity and may play a role in the prevention of cancer.

This study was carried out to investigate the degree of impact from road construction and forest fragmentation after urbanization. And this study was also conducted to compare the urban forest fragmentations of four cities, Taegu, Pohang, Kyungju, and Kumi, in Kyungpook, Korea, with referring the Landsat TM remotely sensed data. Taegu metropolitan city has the largest forest volume of our surveying sites, comparing with three other cities-Kyungju Pohang Kumi city in kyungpook, Korea. The forest has been fragmented during urbanization, the number of forest patch has been increased, therefore, the patch size has been smaller. The forest in Pohang and Kyungju city represented the intermediate aspect between Taegu Metropolitan city and Kumi city, it means forest of the region has been stable condition. Road construction brings to increasing edge habitat area. However, as the core area was decreased, the habitats have been unstable. This result can be a basis on the management of the forest which is the origin of biodiversity. Hereafter, if the research, based on the multi-temporal remote sensing data, is proceeded continuously, the forest fragmentation will be able to be reduced. We will be able to settle urban forest management more practically.
