도시가 이루는 자연성과 주변환경에 이반(離反)되는 개발계획은 건축 후 많은 문제를 발생시킨다. 특히 도심 아파트의 고층화, 집단화와 도시 무절제한 확산에 따른 자연경관의 훼손 및 기존거주자의 전망의 침해는 지금까지 많은 민원과 민사를 야기 시키고 있으며, 지역 외 전문가나 방문자들의 객관적 평가에서조차도 심각한 도시문제로 지적되고 있다. (중략)

More and more domestic skyscrapers have been rapidly constructed to get enough living space for people living in overcrowded cities. The purpose of skyscrapers is to provide citizens with useful facilities and to establish landmarks and also national and regional symbols. Previous studies have been conducted which focused on the structure, materials, plans, maintenance, and relevant information regarding skyscrapers. Skyscrapers, however, are different from other smaller buildings regarding the residential environment as well as in other ways. Recently, several problems have been raised in that the indiscreetness of current skyscrapers cannot guarantee residents a high quality living environment, and they might contain risks unless criteria are put forward to ensure that the design and facilities provide for this aim. It is judged that a set of performance criteria for the residential environment to ensurethe residents' quality of life could solve this problem. This study therefore aims to suggest a method for the improvement of the residential environment of skyscrapers by establishing residential environment evaluation factors. In conclusion, this study calculates the weight of each evaluation factor using AHP (an analytic hierarchy process) and suggests evaluating criteria. It is expected that this study could be used to propose guidelines for residents at the design and planning stage of building a skyscraper.

최근 일부 도심 지역에서 중산층이 특정지역으로 몰리며 원래의 거주자를 밀어내는 젠트리피케이션 현상과 주거비용 상승으로 인하여 도심에서 농촌으로 이동하는 유턴현상이 일어나고 있다. 이러한 이유로, 서울의 인구는 2016년 기준 28년 만에 천만 명이 붕괴되었다. 서울의 감소된 인구는 자연스럽게 수도권 외곽이나, 지방으로 분산되었고, 지자체의 인구가 초고령화로 나아가는 현재의 상황에서 지역사회에 도시민과 자본의 유입은 균형 있는 지방자치에 한 걸음 다가갈 수 있는 방법으로 활용 가능하다. 이와 같은 배경으로 풍부한 관광 자원과 지리적 이점 등을 이용하여 자본의 유입이 많을 것으로 예상되는 강화도 지역에 대해 강릉 카페거리 사례를 바탕으로 젠트리피케이션 모델을 검토 하고자 한다.

오프 그리드 형태의 소형풍력발전기는 도심지 또는 사람이 거주하는 지역에 설치되므로 소음, 진동, 안전성 등에 많은 문제가 야기되고 있다. 풍력발전기 내부적으로 소음 및 진동에 가장 큰 영향을 미치는 요소는 코깅토크로 발전기 회전자가 회전할 때 고정자 슬롯과 회전자 영구자석 사이 공극 릴럭턴스 변화에 의해 발생한다. 또한, 코깅토크는 풍력발전기의 초기 기동 풍속에 영향을 미치며, 토크리플 증가의 원인이 되어 코깅토크 저감 설계는 소형풍력발전기 설계에서 필수적으로 이루어져야 한다. 본 논문에서는 실험계획법을 진행하여 이중고정자 발전기의 영구자석 형상 최적화 설계를 통해 코깅토크를 저감 설계를 실시하였으며, 추가적으로 발전기 출력 전압 고조파 발생을 저감시켰다.

This study tried to explore the quantitative travel heterogeneity between elderly and non elderly people, focusing on urban and rural areas in south Chungcheong province. For the analysis, a PLS(Partial least square) model is applied with economic and traffic environment characteristics of the urban and rural areas. The characteristics of elderly and non elderly people in the urban and rural areas are derived from the 2011 person trip survey. As a result, the study found out that the key factors affect on elderly people in the urban and rural areas are bus operation interval, number of bus operation routes, number of household member, and a monthly average income of household. In case of non elderly people, areas economic factors such as GRDP, the rate of economic activity, and employment status as well as those of elderly people. Meanwhile, female elderly people in rural area have more sensitivity compared to male elderly people and the gender heterogeneity is not revealed in non elderly people.

High-rise residential complex type is getting important as new town development and urban regeneration in the downtown area. However, literature review of high-rise residential complex and research on satisfaction analysis of real residents are lack. Therefore, this paper is analyzing environmental friendly planning elements of high-rise building as housing subdivision, inside of building, facility, and maintenance by a survey on experts. The purpose of this paper is to suggest improvement method of environmental-friendly planning elements of high-rise residential complex by M-IPA. First, as a result, the part of housing subdivision has to keep complex land utilization, environmental-friendly transportation. Second, the part of inside of building shows that ecological housing subdivision, indoor air environment urgent and indoor temperature environment keeps maintaining. Finally, the part of facility/maintenance shows that material and facility, and index of energy management are urgently needed.

The purpose of this study is to analyze both residential conditions and the resident impressions of the transition zone of central Daegu. The results drawn from a questionnaire survey of the residents are summarized as follows: 1) The proportion of people over the age of 60 living on a low income is high and consists mostly of retired citizens who have lived in the transition zone, in their own homes, for an extended length of time 2) The condition of infrastructure in the transition zone is very poor, however, despite the housing deterioration, the internal repair and maintenance of houses is more satisfactory than their external appearance. 3) Residential satisfaction received high ratings in every category except pollution and housing price. This response appears to stem from the easy commute of residents as well as the ready availability of facilities in the city center. 4) In terms of residential satisfaction, the residents can be divided into two groups. The first, with a high satisfaction rate, consists mainly of senior citizens who possess both personal homes and a stable living, having resided in the city center for most of their lives. The second, with a lower satisfaction rate, is composed mostly of younger residents who have lived temporarily in inexpensive rental homes. As a results, the residential area in the transition zone of central Daegu does not appear to be a problematic area like the slum of the West, but instead a stable settlement for its residents.

The government is planning to link a small park with the soon to be ready subway line 9 as a part of Seoul's policy, "The standard or plan for making a water-friendly space by water use" (2007). However, the specified concepts and instructions of the small parks need further work. Therefore, the policy is expected to expand to neighboring small parks near the subway station, but these are not supported by research or data which suggests the needs or actual user behavior and utilization of small parks. our country added the specified concept of small parks and theme parks to the classification of urban parks in the Urban Park Act Revision (2005.3.31), but the concept of small parks is not clearly settled in the law in the scopes of its function, scale, promotion nor particularly defined plans for small park projects. This study examines as small park near a subway station. The characteristics of there region and users vary from the characteristics of the station and region. In the "directions for concrete standards under the types of urban parks and green zones" (2007.2) the types of small parks are classified by "regional characteristics" and "user characteristics". Therefore, this study classifies the subject of neighboring small parks near subway stations as the neighborhood and small urban parks according to the Urban Park Act. The study was paralleled with observation and questionnaires on the analysis of the neighborhood and small urban parks. The actual conditions of park utilization and user behavioral characteristics were deducted by observation, while the questionnaire determined actual user utilization, importance and satisfaction level as well as the small park environment. This study largely focused on three aspects: park facility, design of this sentence isn't even complete. The second aspect isn't finished and the third isn't here.

The purpose of this study is to suggest factors for village activation and maintenance of urban village community, based on the survey of residents' interaction (neighbors relationship, using community facilities, and community activities) and their community consciousness of Seongmisan village, a successful case in Seoul. 171 residents answered the questionnaire, and the data were analyzed by the SPSS program. Major findings are as follows. 1) Families got social with neighbors, caused by common use of community facilities, nearness of houses, and kids' friendship; the number of neighbors to be expected to give help was mostly under 5. 2) Facilities used by residents more than 3 times a week were cooperative association and cafe 'Little Tree'. Facilities considered to be important by residents were living cooperative association('Doore'), kids daycare center, village school, cafe, and education center. 3) 'Village News' was mostly interested community activities; 'Village Festival' and 'Village Sports Day' were also mostly participated. 4) As for the village consciousness factors, more than 3 points of 5 marked in all the 3 categories; emotional intimacy, neighbor homogeneity, and village attribution. The village consciousness, however, showed statistically meaningful difference in residents' motivation to move into village, number of family members, age, income, period of residence, neighbors relationship, whether they participate in group activities and events or not.

The light rail transit (LRT) having bus lines as subsystem is being constructed or planned in the suburban area of metropolitans and medium size cities. However, there is difficulty in establishing the service coverage (SC) of the LRT because the LRT is a completely new transit mode in Korea. The purpose of this study is to provide the basic data and techniques to be used for establishing the SC of the future LRT by understanding the SC characteristics of buses and subways and building models to estimate the walking distances of their users. Busan City is selected as the study city and the SC's of buses and subways are surveyed simultaneously. A total of 9 variables for 82 stations are collected and the cluster analysis is conducted about the variables. The station areas are divided to three types of CBD (Central Business District), sub-CBD and regional center based on the analysis. A station in each area is selected as the study station. At the walking distance (WD) analysis for each mode, the 80 percentile WD of the subway is 672 m and that of the bus is 472 m. In comparing the SC's of both modes by the type of station areas, there are not significant differences between the SC's of sub-CBD and regional center except CBD. At analysis of the relationship between the personal attributes and the WD, for subway users the WD of female is longer than that of male and apartment residents use subway more positively than single house residents do. For the models to estimate the walking distances, the simple regression models were built employing the income as independent variable by dividing the stations into CBD abd non-CBD stations.
