In the traditional subsistence farming era in Korea, most of small farmer's housing plots in the rural villages had their boundary barriers of which materials being the natural ones provided from nearby places. However, during the rapid industrialization period from 1960s, a traditional type of boundary barriers in the rural villages had been replaced mostly by low-cost factory-made ones, which means absolute loss of their amenity values as a linear part of villagescape. In spite of many study efforts on boundary barriers of traditional rural houses, detailed historical dating on them after 1960s have not tried up to now, which provoked to try this study. Through the direct and in-depth interviews to rural villagers sampled from 21 case villages, it was found that original boundary barriers structure in most of farm houses was made of natural materials like stone, soil, trees and bamboo, but, replaced by cement block structures mostly during Saemaeul Project period. However, although being relatively minority, traditional ones have been preserved up to now mainly in remote mountainous and seashore villages, but was in very low condition. In the overall view, for more than half a century, boundary barriers of farm houses had been left without public or private improvement efforts. In order to enhance their amenity values, more research works should be carried out on positive reassessment of the traditional ones harmonized with multifunctionalities for modern village life.

The purpose of this study is to draw safe environmental project factors for enhancing the safety of children in peripheral space around children's park and suggest environmental project measures for peripheral spaces around children's parks, based on the survey of children's park users' consciousness on peripheral spaces. Physical space range for this study was limited to low-rise housing area wihtin the radius of 250m, as peripheral spaces around children's parks in which children's playgrounds were built. In addition, the target areas for examining users' consciousness on peripheral spaces around children's parks were selected according to following criteria. 1)areas with highter portion of children; 2) those with higher portion of single-family houses/multi-housing/tenement houses, which constitute low-rise housing areas; and 3) those with higher safety accident rate of children, which was measured based on criminal and traffic accidents. The finding are as follows: first, users' consciousness on safety accidents that are likely to occur in peripheral spaces around children's parks was examined to show that there is most prominent difference between satisfaction and necessity. This result suggests that users are clearly conscious of the necessity of environmental improvement rather than the satisfaction with the current peripheral environment around children's park.; second, for the difference between satisfaction with and necessity of environmental project factors for access/boundary spaces around children's pakrs, there is most significant difference between the satisfaction with and the necessity of establishment of facilities against illegal parking for clear visibility of community roads, for access spaces, and the separate establishment of bicycle racks around main entry into parks, for boundary spaces. Users' necessity of the establishment of them is judged to be derived from the fact that the safety of children and even adults is threatened, because bicycles invaded into the deep inside of children parks. This study analyzed a correlation between satisfaction and necessity through factor and IPA analysis, and should be initially considenred if the future environmental improvement project would be conducted to promote safe environment in peripheral spaces around children's parks in the future. It will be necessary to provide practical environmental project factors through a field investigation.

During the performance of large scale tidal land reclamation project along the coast line, the construction of large scale structures such as sea-dikes, closing estuaries will induce big changes of near-shore hydraulic behavior. In this paper, its is aimed to verify the change of tide and currents after the construction of sea-dike of the Saemangeum project along the coast line. Numerical scale model "TRISULA" which development by Delft Hydraulics in the Netherlands was used. "TRISULA" is adopting the finite difference numerical scheme, and mostly using for hydro-dynamic solution along the sea and estuaries. Model boundary is covering $100{\times}170$ Km and constructed with $133{\times}337$ grids. Outer side boundary is divided 48 sections, and input 37 tidal components are gained from another big scale numerical "Yellow Sea" model. Model calibrations & verifications were performed th field tide & current datas which were measured along sea-dike alignment during Aug. $1997{\sim}Apr$. 1999. And then, numerical simulation with the tide condition dated 17 Apr. 1999 was performed with & without sea-dike construction condition for the comparison. Evaluated boundary is 20 km out-side from sea-dike alignment. Four cross lanes were set up, each of lane contains 3 points, for the comparison of sea-dike construction effects. Results showing the tidal amplitude is reducing approximately 20 cm after the construction of sea-dike during spring tide condition, amplitude 6.9m. Currents after construction of sea-dikes along the alignment, the northern part shows 50%(inner), 90%(outer) and the southern part shows 10%(inner) 50%(outer) of the currents before construction.

지적공부의 세계측지계 변환은 토지소유자의 재산권 보호와 직접적인 관련이 있기 때문에 좌표변환에 따른 공부상의 경계와 면적변화를 최소화할 수 있도록 해야 한다. 하지만 일반적으로 수학적인 변환식을 이용한 좌표변환은 지적도면의 형상을 변환 전 후에 정확하게 유지하기는 매우 어렵다. 현재 지적재조사 사업의 좌표변환 모델은 Helmert 변환방식에 의한 4개 변수를 이용하고 있으며 이중 축척계수는 동일 필지내에 경계점 간 상대적인 위치의 변화와 면적변동에 가장 민감한 영향을 미친다. 본 연구에서는 경계점 좌표등록지역 지적공부의 세계측지계 좌표변환 시 토지소유권과 관련이 있는 경계점에 대한 오차를 공차 범위 내에 유지시키면서 면적의 변화가 없도록 축척계수를 고정할 수 있도록 Helmert 변환식을 응용한 3변수변환 방법을 제시하였다.

IT project teams are composed of experts from various domains with different backgrounds, such as business and technologies. Thus, enhancing knowledge sharing and increasing team social capital are critical for the success of the project. This study examines the relationship among the team social capital, team climate and team performance. A research model and hypotheses are developed from literature review and empirically validated. The research model consists of team social capital, team climate and team performance. Specifically, team social capital, as antecedents, wasconceptualized asinternal and external differentiated by team boundary, and team climate is conceptualized as innovative climate and supportive climate. Using measures adopted from previous studies, 166 data points were collected to test the research model and related hypotheses. PLS data analysis indicated that internal and external social capitalhave positive effect on innovative climate while internal social capital has a positive effect on supportive team climate. The innovative and supportive climate has significant effect on the team performance. Based on the results, we proposed several team management skills for IT project managers. Theoretical constributions are discussed at the end with limitations and further studies.

현재 우리 나라에서 사용되는 주제도는 수십종류가 있다. 그 중 제작기관내에서만 이용되는 주제도가 있는가하면, 여러 기관에서 공통적으로 이용되는 주제도들도 있다. 이 글에서는 먼저 여러 가지 주제도 중에서 수치지도화 해야 할 공통주제도들을 분석하여 사업추진 우선순위를 제시하였다. 우선순위에서 1등급으로 분류된 공통주제도 중 토지이용현황도, 지형지번도, 행정구역도, 도시계획도, 도로망도 등 5개를 선택하여 제주도를 사례지역으로 수치지도를 실험제작하였다. 실험제작을 통해 공통주제별로 가장 합리적인 제작방법을 도출하고, 실험제작 과정에서 도출된 문제점을 분석하여 향후 국가 GIS사업에서 공통주제도 수치지도제작 결과를 바탕으로 공통주제도의 수치지도제작사업 추진방향을 제시하고, 아울러 전국적으로 확대제작하는데 소요될 예산, 인력, 기간 등에 관한 물량을 추정하고 구체적인 추진방안을 제시하였다.

In recent years, the automotive industry has known a remarkable development in order to satisfy the customer requirements. In this paper, we will study one of the components of the automotive which is the twist beam. The study is focused on the multicriteria design of the automotive twist beam undergoing linear elastic deformation (Hooke's law). Indeed, for the design of this automotive part, there are some criteria to be considered as the rigidity (stiffness) and the resistance to fatigue. Those two criteria are known to be conflicting, therefore, our aim is to identify the Pareto front of this problem. To do this, we used a Normal Boundary Intersection (NBI) algorithm coupling with a radial basis function (RBF) metamodel in order to reduce the high calculation time needed for solving the multicriteria design problem. Otherwise, we used the free form deformation (FFD) technique for the generation of the 3D shapes of the automotive part studied during the optimization process.
