In the study of library history in our country, the history of the Koryo Dynasty is very important. The Pisosong, the first library to be operated by the government, was founded in 995 .A. D. Although research about the Pisosong indicated that it was located outside the palace the author felt that further investigation was needed. Might not the library be located inside the palace\ulcorner For this reason, this study examined 1) the historical background of the Pisosong, 2) changes in its structure and organization, 3) its organization and personnel, 4) its function and, 5) its relation to the Pigak and the Osowon. The findings of this study may be summarized as follows: 1) Pisosong was changed and reorganized 15 times by the end of the Koryo Dynasty. 2) Its functions were keeping official documents and books, buying, exchanging, publishing, editing, revising books, writing official documents for the king and, as a place to discuss ideas and sometimes to deliver lectures to the king. 3) Osowon was another institute which was equivalent in its function and role to the Pisosong. 4) The Pisosong was in all probability located inside the palace because there were very important books in it. It is assumed that its location should be a secure place. Also this would enable the library to be managed more conveniently. 5) The Pigak in the Koryo Dynasty must have been located inside the palace as the Piko in the Sung Dynasty in China was.

Traditional markets located in local small towns have effected local economies and culture for a long time, but their current situation is not so good. In this context, this paper tries to find out the physical characteristics and problems of local traditional markets and to extract some suggestions to improve them. For this, I selected three traditional markets as case study areas such as Mugeuk, Samseong, and Boeun located in local small town in Chungbuk Province. Using the diverse survey methods including theoretical review, basic data analysis, field survey, and questionnaire study, I examined physical features such as location, spatial structure, type of business, streetscape, and convenient facilities in the designated markets. Finally, based on this, I proposed some suggestions on the improvement of traditional markets located in local small towns as followings; expand and improve the convenient facilities, enforce the image of entrance, boost and form groups of specified business, reflect the local characteristics, and amend the related institution etc.

The distribution of corticolous lichens had been investigated in the suburb of Seoul in which factories are located densely and Yeosu which located near sea and very few factories are seen in the neighbour. Ten cm point frame was located at random on the trunk of Pinus densiflora, Quercus serrata and Carpinus Tschonoskii from bottom at 0.5m intervals to 8m height of each trees. The occurrence of each species was represented as a percentage of total quadrat frequency and of density. The density of the corticolous lichens was 2.8%, 6.9% and 7.6% at Dongkooneung, Kongneung and Kwangneung apart 15km, 25km and 32km from center of Seoul respectively. In Yeosu district, the occurrence is fairly different from that of Seoul: it is 34.8% and 34.9% at Odongdo and Hoamsan which located within 3km and 5km from the center of Yeosu. The greater frequency of the lichens on the trunk was found at 1~2m height of trees and they were found mostly on the trunk faced south. However, Pertusaria trochophora species occurred more often on the trunk faced east, Graphis scripta on east and north, Parmelia pertusa and Parmelia tinctorum on west side of trunk. Parmelia pertusa increased with increasing height of trees, but Calicium trabinellum and Anzia japonica decreased. Cetraria collata occurred mostly on the middle of above two species. SO2 concentration in the air of Seoul was high enough to eliminate the lichens except Pertusaria trochophora and Graphis scripta.

The purpose of this study is to investigate how a fully restrained bolted beam splice affects the connection behavior as a column-tree connection in steel special moment frames under cyclic loading when located within the plastic hinge zone. The impacts of this attachment in protected zone are observed by using nonlinear finite element analyses. This type of splice connection is designed as slip-critical connection and thereby, the possible effects of slippage of the bolts due to a possible loss of pretension in the bolts are also investigated. The 3D models with solid elements that have been developed includes three types of connections which are the connection having fully restrained beam splice located in the plastic hinge location, the connection having fully restrained beam splice located out of the plastic hinge and the connection without beam splice. All connection models satisfied the requirement for the special moment frame connections providing sufficient flexural resistance, determined at column face stated in AISC 341-16. In the connection model having fully restrained beam splice located in the plastic hinge, due to the pretension loss in the bolts, the friction force on the contact surfaces is exceeded, resulting in a relative slip. The reduction in the energy dissipation capacity of the connection is observed to be insignificant. The possibility of the crack occurrence around the bolt holes closest to the column face is found to be higher for the splice connection within the protected zone.

This is a report of 3 cases of tumors, which primarily originated from ribs and the sternum. In the first case of multiple myeloma, the patient was 67 year old male with a tumor located on the middle sternum invading the manubrium and the body of the sternum manifesting symptoms after a contusion of the anterior sternum. The sternum was entirely resected and was replaced by tantalum plate to reconstruct the defective chest wall in order to prevent the paradoxical movement during respiration. In the second case of osteogenic sarcoma, the patient was 43 year old male with a tumor located on the costochondral junction of the left 5th rib for 6 months. The left 5th rib was resected between the middle part and sternochondral junction of it including tumor and adjacent soft tissues. In the third case of chondrosarcoma, the patient was 36 year old male with a tumor located near the posterior angles of the right 7th and 8th ribs manifesting back pain on the area where the tumor was located. Resection of right lower lobe was performed since direct invasion of tumor was seen in the superior segment of right lower lobe. This was followed by the resection of both 7th and 8th ribs at the area between the costovertebral junction and the portion 10 em apart from the tumor including the tumor and intercostal soft tissues. Diagnoses of 3 cases of tumors described above were confirmed by histopathologic examination postoperatively. The postoperative courses were uneventful.

To know a degree of pollution in agricultural products cultivated around 4 unworked mines located in Chollanam-Do, we investigated a concentration of heavy metal and trace metal to provide the basic data for its residual limits. 28 samples of seven kinds of agricultural products(lettuce, onion, potato, radish, pepper, pumpkin, bean) collected from 4 unworked mines located in Chollanam-Do in 2001 were analyzed by Mercury Analyzer for mercury and Atomic Absorption spectrophotometer for Pb, As, Cd, Cu, Mn, and Zn. Hg contents were detected N.D. ∼trace level(0.01 ppm and less) and As content were detected N.D. ∼ 0.029 lpm but most of same)leE were not detected. Cd contents were detected N.D∼0.124 ppm. The results of Hg, As, Pb and Cd content showed that for all the 7 species of agricultural products studied, none have accumulated levels dangerous enough to Pose health problems. The average contents of Cu were 3.070 ∼ 7.825 ppm in bean, the Mn were 3.688 ∼23.935 ppm in lettuce ailed the Zn were 5.690 ∼21.171 ppm in bean, respectively.

The objective of this study is to analyze the utilization patterns of other region inpatients in general hospitals located in Seoul area. For the analysis, the study utilize the nationwide data on '2008 Survey of Patients' of Ministry of Health & Welfare. The statistical methodology used in the study is the logistic regression model. This study has three major findings. First, the significant affecting sociodemographic factors in selecting general hospitals located in Seoul area was sex, age, type of payment and inpatients residence region. Second, compared to other disease groups, the inpatients on both 'congenital malformation, deformity and chromosomal abnormalities' and 'neoplasm' groups are more likely to utilize general hospitals in Seoul area. Furthermore, in 'neoplasm' disease group, inpatients with 'bones and articular cartilage malignant neoplasm' are more likely to utilize general hospitals in Seoul area. Finally, hospitals with more than 1,000 beds was chief factor in selecting Seoul-based hospitals by other region inpatients. In conclusion, the study showed that other region inpatients are more likely to utilize general hospitals located in Seoul area in case of severe disease, rare case and surgical case. Therefore, central and local authority is required to monitor local hospitals on quality of the medical service as well as support them to establish specialized medical centers by providing human and physical resources.

Analysis of a structure for vertical vibration requires a lot of computational efforts because large number of degrees of freedom are generally involved in the dynamic response. Especially, when a structure is loaded with local vibration source, it may not be economical to model the whole structure to obtain the responses of specific members located near or far from the sources. In this study, substructure models have been used for analysis of local vibration An analysis of local vibration is performed for the case that the loaded point and the response point are located on the same floor. Other analysis is performed for the case that the loaded point and the response point are located on the different floor. In this case, if only the floors on which loaded and response points are located are modeled, response of substructure model is very different from that of full model. So, there should be a consideration that degrees of freedom of floors in addition to those of loaded and response floors are included to improve results of dynamic analysis. In this study, floors between loaded floor and response floor were modeled so that modeshapes which affect the response are presented well.
