한국 목조 건축에서 외형의 아름다움을 결정하는 요소로 지붕의 형태는 매우 중요하다. 그 가운데에서도 처마의 곡선은 한국 목조 건축의 특징을 가장 잘 나타내는 요소이다. 이 처마의 곡선을 만들어내는 것이 바로 서까래와 부연(浮椽)이라는 부재이며, 특히 날렵한 처마곡을 만들어 육중한 지붕의 느낌을 보다 가볍고 역동적으로 보이도록 하는 것은 부연이다. 부연의 기능과 역할에 대해서는 이미 알려져 있지만 처음 사용 시기와 관련해서 명확하게 알려진 바는 아직 없다. 이에 따라 본 연구는 한국 건축에서 부연이 최초로 사용된 시기를 규명하는 것을 목적으로 한다. 이를 위하여 먼저 한국·중국·일본의 고대 건축과 관련된 기록이 남아 있는 문헌, 발굴 유구, 현존 건축물과 건축물이 표현된 회화 및 조각 등의 고찰을 차례로 진행하고 이를 종합하여 한국 고대 건축의 부연 사용 시기를 추정하고자 하였다. 그 결과를 정리하면 다음과 같다. 첫째, 중국의 경우 6세기 중반 북제에서 처음 부연 사용이 나타나지만 일반화된 것은 당대인 7세기부터로 판단된다. 둘째, 일본의 경우 수도를 비조 지역에서 나라 지역으로 이전하는 8세기 중반 이후 부연 사용을 확인할 수 있으며, 이는 중국의 당과 직접적인 문화 교류를 추진하는 시기와 겹친다. 셋째, 한국의 경우 부연 사용은 6세기 중반 중국 북제로부터 백제로 도입되었을 가능성이 있으나 일반화되지는 못하였던 것으로 보이며, 이후 신라 통일기인 7세기 중반 중국 당과의 활발한 교류가 이루어지면서 보편화되었던 것으로 판단된다.

Rafter is a member for roof and plays a role in protecting shaft members under rafter such as pillar, beam and girder from natural environment and to fix by supporting finished materials of roof. It is common in the Korean architecture that rafter cross-section is paired with circular form and Buyeon cross-section is paired with the square shape. However, while there are not many, some architectures have rafter end header in the square shape. The aim of this study is to examine the square shape cases of rafter end header with special reference to stone structure. As a result, among stone structure related to Bangyeon, the majority case is seen at Palgakwondang type Seungtap. It was shown in the Seungtap of monk of Gusanseonmun school in the later Unified Silla to the early Goryeo period that succeeded Seodang Jijang.

Economy of scale would be one of the most important issues among organizations pursuing system integration projects. Cerntainly there are other benefits than cost reduction for achieving system integration. However. these benefits could not be achieved automatically. if system integration projects were undertaken without thoughtful planning. In this paper. we propose a framework for an effective system integration by (1) defining the objects(user interface. database. application. and server) and (2) considering the level of integration(physical integration and rational integration). Therefore. 6 types of integration can be considered. Five case studies of domestic organizations were reviewed to suggest various issues and solutions. Based on our case studies. we discovered that five integration types - EIP. EAI. ERP. BPM and System Reconsolidation - were most widely used.

The purpose of this study was to evaluate the safety of the small reservoir, which is distributed in a rural area, based on systemic reliability. It has been estimated that safety of respective reservoir the calculation of failure probability for individual reservoirs can evaluate the safety of the reservoir of the study area. The change of safety for watershed could be figured out as that result. Probability of failure was increased from $3.90{\times}10^{-5}$ to $1.35{\times}10^{-4}$ in Naesu-inpyung reservoir, from $1.33{\times}10^{-5}$ to $4.77{\times}10^{-5}$ in Buyeon reservoir and from $4.24{\times}10^{-5}$ to $2.55{\times}10^{-2}$ in Dalakmal respectively. From the results, the collapse of the upper stream reservoir was analyzed qualitatively that may affect the safety of the reservoir on the downstream area.

The purpose of this study is to classify types of the eaves structure of buildings with the Jusimpo-type structure and to analyze the characteristics of each eaves structure. For this objective, forty buildings were selected and investigated. The results of analysis are summarized as follows. First, the main members of framework which handle a load burden on the long-rafter(長椽) are classified as the Jusim-dori(柱心道里) and the Oemok-dori(外目道里). Based on the method of handling a load, the eaves structure is classified into three types; the Jusim-processing-type(柱心中心形), the Oemok-processing-type(外目中 心形), and the Oemok-processing-variant-type(外目中心變異形). The Jusim-processing-type is the set where the internal length of a long-rafter is longer than the length of the eaves on the basis of the center of a column. The Oemok-processing-type is the set where the external length of a long-rafter is longer than the internal length of it. And the Oemok-processing-variant-type is the set where the internal length of a long-rafter is longer than the external length of it, but it is shorter than the length of the eaves which includes the extruded length of a Buyeon(浮椽). Second, the Jusim-processing-type had been generally adopted in the Jusimpo-type structure of the Goryeo Dynasty. But since the 17th century, the Oemok-processing-type had the highest application rate. Third, the change from the Jusimdori-processing-structure to the Oemokdori-processing-structure means that the long-rafter is moved to the direction of outside of the building, and thus the Jung-dori(中道里) is gradually moved to the column center. And, the change of the eaves with the Jusimpo-type structure was not a process for increasing the length of the eaves but a process for adopting the advantages of the Dapo-type structure by changing the arrangement of purlin. Fourth, the change from the Jusimpo-type structure to the Dapo-type structure could be understood as a process for moving the main point for handling a load from the Jusim-dori to the Oemok-dori.
