This research This research aims at developing systemic evaluation model in terms of biotope preservation through reports, literatures, and expert survey analysis by implementing biotope structure analysis in area level with selecting Hyunpoong and Yuga-myeon, Dalseong county, Daegu metropolitan city as a site. First of all, as a result of biotope type classification of research site, biotope type groups are classified into total 13, and its biotope types are divided into total 61. Also, as a result of literature analysis, total 18 items are drawn such as diversity of biotope typical species as a index item to assess the preservation value of biotope, and the first evaluation index are divided into 10 and the second ones are divided into 8 according to characteristic of index items. As a result of expert survey analysis, All 10 index items, first evaluation index, show high importance average (above 4.7). As a result of implementation of main cause for categorizing evaluation index by characteristic, there are 3 factors such as 'obstructive factor.' Based on above survey analysis result, as a result of estimating the weight of each item, 'restoration factor' showed the highest, 3.4541, but 'factor of habitat stability' showed 3.1468, which is the lowest The systemic value evaluation was set by comprehensively analyzing these results. As a result of biotope preservation value evaluation through applying research site, total 19 types which are abundant in vegetation are classified into I class, 12 types in II class, 5 types in III class, 10 types in IV class, and 15 types in V class respectively. Lastly, as a result of second evaluation, it is analyzed that there are 17 special meaningful space to preserve species and biotope(1a, 1b) and 61 meaningful space to preserve species (2a, 2b, 2c).

기존의 인터넷소비자의 방문행동에 관한 연구들이 대부분 전체시장 수준에서 이루어졌고, 시장세분화를 하더라도 사전적 시장세분화로서 연구자의 주관이 반영되는 경우가 많다는 문제점이 있었다. 본 연구에서는 세분시장 수준에서의 인터넷소비자 방문행동 연구가 필요하다는 점과 함께 연구자의 임의성율 배제한 사후적 시장세분화의 필요성을 제기하고 이를 믹스처모델로 실증적으로 분석하였다. 또한 기존 연구가 웹사이트 평가요인과 방문행동 간의 단편적인 인과관계를 파악한 것과는 달리, 웹 사이트 방문행동에 영향을 미치는 요인들 간의 간접효과에 따른 통합적인 인과관계를 파악하였다. 연구에서는 실제 커뮤니티 사이트를 방문한 1,765명 의 웹상의 움직임과 설문조사를 통해 세분시장별로 이질적인 navigation pattern 과 원인변수와의 관계가 존재함을 입증하였다. 마케터는 이런 세분시장멸 이질적 관계를 이용하여 eCRM을 실행함에 있어 navigation pattern의 이질성에 영향을 미치는 변수를 세분시장별로 조절함으로써 기업이 원하는 방향으로 고객의 웹사이트 방문행위를 유도할 수 있는 기회를 얻게 되었다.

This study selects 45 housing complexes in Munheung, Ilgok and Sangmu districts of housing side development zones of Gwangju Metropolitan City and conducts the experiment the visual characteristics of these housing complexes through visual-perceptive information with their residents. As a result of experiment for the evaluation and structurization by visual-perceptive information of view image, there were affirmative evaluations in the whole experimental subjects except variables as 'innovative' and 'new' According to cluster types, while simple reiterative types showed affirmative responses except such items as 'dull', 'common' and 'uniform'. Variational types were affirmative in the whole items. It extracted four evaluation factors including variety, stability, harmony and symbolism. From the above research, it is understood that since the current housing site development has been made after developing housing site by public agencies and sold them to construction companies, housing complexes of different types were built within the same district. Therefore, it cannot be connected to the view of the whole district even if it considered view in planning housing complex. then when future housing side development or housing complex are planned, it is required that view guideline in the dimension of the district should be prepared and housing site development district or housing complex must be able to contribute to urban view by introducing master architect system.

Near-field ground motions exhibit special characteristics that are different from ordinary far-field ground motions. This paper first briefly examines the characteristics of near-field ground motions associated with fault directivity and fling-step effects. Then evaluation of near-field ground motions by inelatstic response spectrum analysis is performed and analyzed. As a result, ductility demand in near-field ground motions is larger in hanging wall than in foot wall in long period regions. Also in long period regions ductility demand in soil site is larger than that in rock site.

The accurate wind speed information at the hub height of a wind turbine is very essential to the exact estimation of the wind turbine power performance testing. Several methods on the site calibration, which is a technique to estimate the wind speed at the wind turbine's hub height based on the measured wind data using a reference meteorological mast, are introduced. A site calibration result and the wind resource assessment for the Taekwanryung test site are presented using a one-month wind data from a reference meteorological mast and a temporal mast installed at the site of wind turbine. From this analysis, it turns out that the current location of the reference meteorological mast is wrongly determined, and the self-developed codes for the site calibration are working properly. Besides, an analysis on the uncertainty allocation for the wind speed correction using site calibration is performed.
