Spatial Structure has suffered from a lot of damage due to the use of lightweight roofs. Among them, the damage caused by strong winds was the greatest, and the failure of the calculation of the wind load was the most frequent cause. It provides that wind tunnel test is used to calculate the wind load. However, it is often the case that the wind load is calculated based on the standard of wind load in the development design stage. Therefore based on this, the structure type and structural system and member design are often determined. Spatial structure is usually open at a certain area. The retractable roof structure should be operated with the open roof in some cases, so the wind load for the open shape should be considered, but it is not clear on the basis of the wind load standard. In this paper, the design wind pressure of a closed and retractable roof structure is calculated by KBC2016, AIJ2004, ASCE7-10, EN2005, and the applicability of wind pressure coefficient is compared with wind tunnel test.

본 연구는 2010년 3월부터 10월까지 강원도 횡성군 청일면에서 갑천군 수백리 일대의 횡성호와 횡성호 상 하류지역을 선정하여 저서성 대형무척추동물의 군집구조, 섭식기능군 및 서식기능군 분포, 생물학적 수질을 평가하였다. 조사지역은 횡성호 상류 2개지점(St. 1~2), 횡성호 2개지점(St. 3~4), 횡성호 하류 2개지점(St. 5~6)의 총 6개 조사지점을 선정하여 총 3회에 걸쳐 계류형 정량채집망(Surber sampler 30cm×30cm, 망목 0.2mm)을 사용하여 정량채집 하였고, 조사지점별 정확한 저서성 대형무척추동물상을 파악하기 위하여 각 조사지점에서 미소서식처에 따른 정성채집을 병행하였다. 조사결과 총 5문 8강 17목 43과 83종이 출현하였으며, 하천의 주요 분류군인 하루살이-강도래-날도래군(EPT-group)이 50종(60.24%)을 차지하였고, 파리목(Diptera)을 더하면 61종(73.49%)으로 전체 출현종의 대부분을 차지하였다. 정량분석시 횡성호 상류지역의 저서성 대형무척추동물은 총 4문 4강 11목 28과 54종 2,399개체, 횡성호에서 총 3문 4강 7목 12과 16종 510개체, 횡성호 하류지역에서 총 4문 6강 13목 33과 62종 626개체가 출현하였다. 군집분석 결과 우점도지수는 0.82~0.93(0.87±0.05)으로 횡성호에서 높게 분석되었고, 다양도지수는 3.04~3.16(3.10±0.06), 균등도지수는 0.79~0.85(0.82±0.03), 풍부도지수는 7.27~8.52(7.90±0.63)로 횡성호 하류지역에서 상대적으로 높게 분석되었다. 섭식기능군은 collector-gatherers와 collector-filterers가 높았으며, 횡성호에서는 predators가 상대적으로 풍부하였다. 서식기능군은 swimmers, burrowers, clingers가 대부분을 차지하였다.

It is important to evaluate energy absorption capacity of frames required during a design earthquake. An inelastic computer analysis based on mathematical modelling of energy absorbing frames and elements makes it possible to evaluate required energy absorption capacity. But such an analysis sometimes consumes much computation time particularly in case of complicated structural system. This paper presents a proposal to predict energy absorption of multi-bent steel frames by simple equivalent linear method.

This study is to analyze the spatial structure and POE of Jungja(pavilion) shelter for rural village regeneration. 14 Jungja shelter space at rural villages in Gyungbuk province, were investigated. An interview questionnaire was conducted for total 139 residents as POE. The use behavior and satisfaction for Jungja shelter space, were investigated. The statistical analysis were mean of satisfactions, reliability, factor analysis, and multiple regression analysis. The results and discussions can be objective data for rural village regeneration. In satisfaction level, ‘Continuous use intention’(3.99), ‘Well-suited approach’(3.87), and ‘Helpful in resident living’(3.84) were shown to be high points of agreement in 5 point Likert type scale. But, the mean points were low as 2.01 in ‘Surrounding landscape’, ‘Creation of green areas’(3.22), and ‘Traffic safety’(3.22), respectively. Within use satisfaction, 5 factors were categorized, ‘Use’, ‘Safety’, ‘Facility’, ‘Management’ and ‘Users’. By the result of multiple regression analysis, variables of ‘Continuous use’, ‘Convenient location’, and ‘Image improvement’, were shown to be main affecting variables to overall satisfaction. Furthermore, in spatial structure analysis, 4 types were categorized with the aspect of landform, roads, and location in village. The levels of satisfaction were shown to be high in village type of semi-open, road type of circular, and location type of center/back. Conclusively, these findings could be utilized as basic data and useful tool of space-structural satisfaction analytic method, and for each stage of planning/design and remodeling for rural village regeneration.

The purpose of this study is to show the relation of the change between spacial structure and social conditions of rural area. The spacial structure change of Asan city was analyzed using Space Syntax, and multiple regression analysis (dependent variables: connectivity, global integration, local integration / independent variables: population, household, farm population, farm population of 65years old and over, farm household, part-time farm households, cultivated land) was accomplished. As th result, that the increase of connectivity is related to the increase of population and farm population of 65years old and over and the decrease of farm population, and the increase of local integration is related to the increase of farm population of 65years old and over was showed. However, that global integration is not related to change of social conditions was proved.

Landscape structure is important to understand a complex patterns and interaction with adjacent habitat in rural area. The aim of this study is to analyze relationship between landscape structure and insect spatial distribution in rural area to suggest applicable possibility of landscape structure as biological indicator. For this purpose, first, four landscape structure criteria such as distance from the forest; density of farmland-forest ecotone; landscape continuity; and field size are selected. Secondly, these criteria are applied to Gangsang-myeon, Yangpyeong-gun where mosaic feature are conserved at various spatial scale. Thirdly, application of landscape structure criteria is verified using correlation with species number, species diversity, and species richness of insect. As a result, it could be suggested that the landscape structure criteria are useful for explaining insect spatial distribution.

In order to revitalize rural areas fundamentally through multifunctional utilization of their resources, it should be necessary to prepare the rational development plan to the areal characteristics and conditions, and the first priority of its planning works should be given to spatial planning. The space syntax method, a powerful objective and quantitative analysis tool on the relationship between social and spatial characteristics, was introduced in this study. Five Comprehensive Rural Clustered Villages Development Areas in the Jeonnam-province were selected as case study areas, of which total area's and included villages' spatial variables were measured and analyzed. Rural villages analyzed in this study have the spatial structure badly systematized and much complicated, which results from low integration and deep spatial depth of them. And, by virtue of relatively many axial lines, there should be few differences between villages in terms of local integration, connectivity and control, while being significant difference in terms of global integration showing the whole areal characteristics. Intelligibility, the correlation coefficient between connectivity(local variable) and integration(global one) is low, which means that the spatial structure of the study areas is difficult for visitors to understand the area or village well. Spatial configuration analysis results in the case study areas showed that each development area has a unique spatial structure and is differentiated in terms of not only local spatial variables but also global spatial variables. Therefore, global and local characteristics should be considered in spatial analysis of development areas.
