  • 본 논문의 목적은 고속철도 콘크리트 궤도 및 노반 측정 데이터(노반압력, 진동가속도, 탄성변위 등)를 이용하여 토공노반의 장기거동을 분석하고 궤도 노반의 장기성능을 평가하고자 하는데 있다. 최근 고속철도 궤도 형식이 콘크리트 슬래브로 채택되고 있다. 그러나 콘크리트 궤도는 노반 침하에 취약하다. 자갈궤도의 경우 노반이 침하되어도 유지보수로 원상복구가 용이하다. 반면에 콘크리트 궤도의 경우 노반의 과도한 침하가 발생하면 도상 및 침목에 균열이 지속적으로 발생되고 사용성이 크게 저하된다. 이와 같은 이유로 부분보수만으로 원상복구가 어렵다. 본 논문에서는 운영 중 콘크리트 궤도에 대하여 건설 초부터 매설된 센서의 측정 데이터를 개통 후 약 3년까지 모니터링하여 장기성능평가를 수행하였다. 성능평가 방법은 열차별 궤도 토공노반 및 장기 궤도 노반 성능평가, 장기침하에 따른 궤도 노반 성능 영향 분석 및 장기 침하 영향인자 분석 등이다. 열차별 궤도 노반 성능평가에서는 KTX-산천중련의 노반응답이 가장 컸다. 장기 궤도 노반 성능평가 결과는 측정항목이 기준치이내로 측정되었다. 장기침하에 따른 궤도 노반 성능영향 평가는 TCL처짐은 침하와 깊은 연관이 있는 것으로 분석되었다. 장기침하의 외부영향인자 분석을 통해 함수비와 지하수위의 영향성을 확인하였다. 이와같은 방법을 통해 궤도상 토공노반의 안정성을 확보할 수 있을 것으로 사료된다.

  • The purpose of this study was to analyze the impact on settlement consciousness from the physical change and community development accomplished by the regeneration of a park and green space in a deteriorated residential area. The case study was a park that altered the landscape of a ruined hill in Busan. Two field investigations were performed to determine the condition of before and after the making of the park. A survey was also conducted, the frequency and means were calculated, and multiple regression analysis was performed. The results show, first, the physical regeneration increased the vitality of the place and assisted in the improvement of the community, particularly in satisfaction and attachment to residence, and in the settlement consciousness. Second, the identity of the resident was improved by the regeneration, and they approved of the transformation of an abandoned space into a usable place. Third, the settlement consciousness was significantly reinforced by making the physical environment into valuable space and improving the image of the residential area.

  • 인공어초는 해양환경을 개선하고 어류와 해양생물들에게 주거지를 제공하는 인공 수중 구조물이다. 특히 인공어초가 느슨한 모래, 연약한 점성토와 같은 연약지반에 설치될 경우 인공어초의 자중에 의해 인공어초의 침하가 발생하게 된다. 본 연구에서는 관입실험을 통해 토목섬유 보강 넓이에 따른 인공어초의 지지력 보강효과를 확인하였고, 실내 대형 토조 실험을 통해 침하 저감효과를 확인하였다. 관입실험과 실내 대형 토조 실험을 통해 지오그리드와 같은 토목섬유를 인공어초 하부에 포설하게 되면 지지력이 증가하며, 침하가 감소하는 경향을 나타내었다.

  • This study was examined the level of satisfaction in rural settlement and analyzed its differences according to various demographic variables and characteristics of urban-rural migration. The analysis was conducted by considering returning farmers residing in rural areas. A statistical analysis was conducted using t-test, one-way ANOVA, and Duncan's multiple-range test with a total of 210 responses. First, satisfaction with the convenience of living facilities varied significantly according to the occupation before urban-rural migration, responses of family members and friends to urban-rural migration, and the initial capital for urban-rural migration. Second, satisfaction with the natural environment varied significantly according to age and reasons for urban-rural migration. Third, satisfaction with the transportation environment varied significantly according to gender, the period of residence after urban-rural migration, and the employment type of the returning farmer. Fourth, satisfaction with neighborliness varied significantly according to parents' occupation, agricultural experience before urban-rural migration, experience in agriculture-related social life before urban-rural migration, reasons for urban-rural migration, the type of urban-rural migration, and the employment type of the returning farmer. Fifth, satisfaction with the agricultural environment varied significantly according to responses of family members and friends to urban-rural migration, the period of residence after urban-rural migration, and reasons for urban-rural migration. Sixth, satisfaction with the housing environment varied significantly according to the residential area, the agricultural experience before urban-rural migration, and the period of residence after urban-rural migration.

  • The purpose of this research is to identify the phases of the fashion merchandising process and the range of the fashion designer's work as well as performing degree at each stage according to the brand types of domestic women's apparel. The preliminary research was conducted with the chief designers of five woman's apparel manufactures located in Seoul and the questionnaires were collected from 192 fashion designers. They were measured by the five point Likert-type scales. For a data analysis, the Pearson's Correlation, ANOVA, Sheffe Test, MANOVA were used with SPSS V. 11.0. The results are as follows; 1. The steps which fashion designers of domestic apparel brand take in fashion merchandising process have been identified in 7 stages- Environment Information, Target Market Planning, Design Planning, Design Development, Price Settlement, Presentation & Line Release, Production. 2. The task achievement level of fashion designers in fashion merchandising process differs in brand types as well as in fashion merchandising stages. In NB, the designer's work was conducted in order of Design Planning(M=4.58)$\to$Presentation & Line release(M=4.31)$\to$ Environment Information(M=3.83)$\to$Target Market Planning(M=3.13). In DB, in order of Price Settlement (M=4.80)$\to$Production(M=4.33)$\to$Design Development(M=4.27)$\to$Design Planning(M=3.77)$\to$Presentation & Line release(M=3.20)$\to$Environment Information (M2.70). In GB, in order of Production(M=4.38)$\to$Design Planning(M=4.22)$\to$Price Settlement(M4.16)$\to$Environment Information(M=3.83)$\to$Merchandising Target Market (M=3.72)$\to$Design Development(M=3.65). 3. Considering the other factors such as sales, the amount of owning shops, item amounts that are related to the company size, this study shows that only the brand type affects designer's task achievement.

  • In recent year, construction of national infrastructure, variations of agricultural environment, urbanization of rural life-style, and other things have influenced on rural area. Therefore, its landscapes have been changed rapidly. As a result of it, rural landscape should be controlled with amenity and totality. That is a rural amenity control planning. The purposes of this study is to consider characters of rural settlement area, the directions of landscape control planning as an environmental planning, the structure of rural landscape, the process of rural landscape control planning, and its frameworks. Main viewpoints of landscape control planning in rural settlement are as follows; the using of regional resources, the harmony of surrounding environments, the harmony of natural ecology, locating of facilities, the development of new landscape material, maintenance of sequencing, symbolizing, unificating, and opening, the using of natural/regional materials, the using of waterfront, the making of stories.

  • This study is about the problems found in the process of the current governments planning rural settlement area development. As a measure to solve them, It proposed the analysis method of village characteristic in terms of standard score and tried to use this method as a basic material in planning more effective rural settlement area development. On the basis of the above analysis, which is an objective basic material to solve the problems revealed in the process of the bottom-up development planning by the residents' demands, It shows the following conclusion about what method should be applied to each part according to a village's characteristics and its development level. 1. Accessibility can be a basic material for setting the local area, analyzing its settlement system, and them such development facilities as village-linking roads, rural road, or various kinds of bridges and determining the investment priority. 2. With the index of the industrial basis, we can see what village has plenty of social, economical resources including advanced industrial facilities and looking into the advance level of the industrial basis, we can get some information about determining the local area development direction such as estashing the plan to build a farm product gathering center, a collective work place, storage facilities, and special housing development. 3. Since the issue about living environment is raising it's head, compared to weakened agricultural competitive power, with the analysis of this living environment, we can get an objective basic material for solving problems caused by the local egoism and the effective investment strategy of the limited resources. Therefore, It is necessary that we should abstain from expert-centered planning and formal public opinion-collecting and on the basis of this analytic result, we should plan development. We need to continue our research about index selecting and differentiation, weight etc. and using these analysis methods, we should make up a systematic development plan by analyzing village characteristics and setting the development direction.
