The purpose of this study was to identify the species of the woods used in the main building (Daewoongjeon) of Bulgapsa temple in YeongGwang. Eighty eight woods sampled were divided into four parts; pillars(21), rafters(19), purlins(16) and other wood elements(12). Four species were identified; Pinus spp. (hard pines; diploxylon), Abies spp., Quercus spp. and Zelkova serrata Makino. Pillars and corner-angle rafters were mainly Zelkova; however, other wood elements were mostly Pinus spp. The high ratio of Zelkova in this building would be ascribed to the preference of this species to pines owing to its superior quality before the late Chosun Dynasty.

Daewungbojeon hall of Magoksa temple is a korean traditional wood building well representing Joseon Dynasty architecture in the 17th century. The purpose of this study was to identify the wood species of 42 wooden elements collected from Pillar (Gidung), Head-penetrating tie (Changbang), Pyeongbang, Angle rafter (Chunyeo), End-angle rafter (Sarae) and Hwalju. According to the microscopical investigation, Pillar, Head-penetrating tie, Pyeongbang and Hwalju were identified as domestic hard pine species. However, Chunyeo were identified as either Zelkova serrata Makino or Gingko biloba L. and Sarae as exotic hard pine species. It might be related to the high replace rate of wood elements for the roof. Especially, exotic hard pine species seem to be replaced in recent years when Daewungbojeon hall was repaired.

This thesis mainly deals with the meaning of single eaves buildings which have Chunyeo with Sarae. As a rule, building with single eaves does not construct Sarae. But we can find some special buildings using Chunyeo with Sarae in the corners of the eaves. At this time, many people say that lower part of the member so called Alchunyeo, and upper part of the member so called Chunyeo. And they also say that the using of Alchunyeo was caused by the shortage of timber which can make Chunyeo properly. As a result, single eaves buildings using Chunyeo with Sarae in the corners of the eaves were not caused by the shortage of timber. That kinds of buildings were made by the hierarchy of building. Single eaves buildings with Sarae have lower rank than double eaves buildings, and also have higher rank than those without Sarae. And we have to say that lower part of the member is Chunyeo, and upper part of the member is Sarae.

우리나라의 전력계통은 수도권 전력수요 집중과 대단위 발전단지의 증가, 고장용량의 증대에 따라 고장 발생 시 정확하고 신속하게 조치하지 않을 경우 광역고장으로 파급될 우려가 있다. 전력거래소에서는 전력계통에 고장이 발생할 경우 사전에 검토된 사례를 DB화하고 이를 기반으로 EMS 상태 추정결과에 따라 현재의 계통상황에 유사한 복구절차를 자동으로 계시하여 급전원의 정확하고 신속한 고장복구를 지원하는 시스템을 개발하고자 연구를 수행하였다. 사래기반의 고장복구절차 자동제시를 위하여 계통운영방안 및 휴전검토 시의 검토결과를 자동으로 DB화 하는 프로그램을 개발하였으며 고장발생 시 계통상황을 인식하여 적합한 복구절차를 제시하여 주는 계통감시 프로그램을 개발하였다.

As wooden construction developed, it was observed that the rafters with corners changed to angled rafters. The change from rafters to angle rafters means that the angle rafters became the most important member in supporting the roof weight as the construction scale increased and structurally developed. The specific installation methods of angle rafters were all unique in Korea, China, and Japan. In East Asia, the angle of the angle rafter gradually decreased along with the development of construction. However, in Joseon Dynasty Korea, the angle of the angle rafter was larger than that of the Gorye era because the method of fixing the corner of the roof more firmly by building the fan-shaped rafter was utilized. The changes to the angle rafter installation method is a unique characteristic of Korea, in that it was developed in a totally different way from the methods used in China and Japan.

The purpose of this study was to examine the species of 117 wooden elements which were used in the Daewungjeon Hall (National Treasure No. 805, constructed in A. D. 1659) of Bukjijangsa Temple, Daegu, Korea. Pillars were identified as 5 red pines (hard pines; most likely, Pinus densiflora S. et Z.), 2 Cerris section of subgenus Lepidobalanus (deciduous oaks) and 3 Tsuga spp. Hwalju columns were 3 Abies spp. and 1 red pine. Head-penetrating ties were 8 red pines and 1 Cerris sp.; Pyeongbang, 3 red pines and 6 Cerris spp. Purlins were identified as 17 red pines, 16 Cerris spp. and 1 Tsuga sp. Angle rafters were 3 red pines and 1 Cerris sp., and end angle rafters, 2 red pines, 1 Zelkova serrata and 1 exotic hard pine. All of brackets (31 woods), jangyeo (4) and deot-chunyeo (2) were identified as red pines. As a whole, red pines (70.1%) and Cerris (22.2%) were major species used in the Daewungjeon Hall of Bukjijangsa Temple. Tsuga, Abies and exotic hard pines seem imported woods used for recent repairs.

The purpose of this study is to grasp the present state of a outdoor space planning and to analysis plan characteristics in based on regional characteristics in Housing complex plan. The analysis result of this study is as follows : first, we know that the right of regional characteristics is appearing variously every research workers. also an analysis about regional characteristics that should be considered in housing complex plan was insufficient. Second, regional characteristics can be classified into 5 factors. These are classified as a context of location, city link, life atmosphere, needs of locals and creation of image. Third, it has originality against other housing complex to graft items connected with 'U contest' on outdoor space planning. Also, it has affirmatively effected on image of Buk-gu and recognition of Dong beyn-dong and Seo beyn-dong. It is get out of the uniform design by a planning based on land and surrounding environment in arrangement and forms. Also residents have the satisfaction and pride in arrangement considering the climate of a region and security of the green space.

This study intends to analyze the status and efficiency of education-training in Korean firm. A study on the education-training in firm is very important nowadays, but the study level on this issue in Korea is low. The study method of this paper is the case study on a high-level Korean firm in the education-training status. This study first attempted to analyze the concept and size of the education-training in firm. And then this study figured out factors that determine the efficiency of education-training. Finally, I analyzed the status and efficiency of education-training in this case firm. Unfortunately, the efficiency level of my case firm in the education-training was low, in spite of a high-level firm in the education-training status. To upgrade the efficiency level of this firm in the education-training, this firm has to resolve many tasks.

This paper offers a method to measure the distribution of niches of two types of social organizations. Internet sites and voluntary organizations. based on the socio-demographic characteristics of their members. It examines the niches of Internet sites based on age and education of site visitors and those of voluntary organizations based on age. education. and occupational prestige of their members. The method to measure organizational niches makes it possible not only to understand the niche width of organizations but also to examine the extent to which organizations .potentially compete and coexist. This leads to a method to recognize the way organizational environments influence the performance of individual organizations ecologically. To conclude, this paper shows that organizations are socially embedded through a process of pariticipation in which individual members choose their organizations not randomly. but based on their socIoifemographiccharacteristics.

In this study, Gwanghanru Pavilion (Namwon-si, Cheonbuk Province) was dated by tree rings of pines (Pinus densiflora Sieb. et Zucc., 'sonamu' in Korean). The present Gwanghanru Pavilion is composed of three parts: main, wing and entrance parts. The main part is known to have been built in 1626 and the entrance hall in 1879, but the date of construction of the wing part is still unknown. We dated a total of 55 wood samples which were replaced during the repair process in 2001~2002. Tree-ring dates indicated that both main and wing parts were built in 1626. Tree rings also revealed that the entrance hall was constructed in 1880~1881, and both main and wing parts were heavily repaired together while appending the entrance hall. In conclusion, dendrochronology, i.e., tree-ring dating, was a useful and accurate method to identify the critical dates-such as the dates of original construction, reconstruction, repairs and extensions-for the history of Korean traditional buildings.
