We investigated space establishment and land use of children's parks by studying movement of users in and out of the parks with a questionnaire survey, video and analysis, and then analyzed the characteristics of how the facilities and the space of the parte are used. The results are as follows. First, when considering the character of the facilities of children's parks, entertainment facilities should receive priority followed by those for relaxation and those for convenience. When considering the position of facilities in the parks, because activity spaces may have similar functions to multi-purpose paved spaces, common use of these two spaces should be considered. Entrances and lines of movement should be kept in mind. Second, when considering the surrounding land uses, in case a play facility at a large-sized complex or an elementary school is adjacent, the exercise facilities may be more important, followed by play and rest facilities. In case there is a broad path around the parte, the way in which movement occurs into the central axis should be considered so that the other side of the broad way is not included in the children's play space. Third, proper control of roads adjacent to the parse is needed to protect children from danger.

The purpose of this research is to help outdoor space planning reflected real needs of apartment residents in the differentiation elements of outdoor space, by using USC trade-off game in three apartment complexes in Seoul. This game method was used to evaluate their preference, reliability of preference degree, satisfaction degree, requirement elements such as improvement, sacrifice, maintenance of present condition, and payment possibility for improving and maintaining present condition, in addition to their preference and payment possibility of differentiation of outdoor space in the apartment complex in the future. From the statical analysis, we found the following results: 1. Reliability of preference degree was valid, inasmuch as the first elements they preferred were the almost same as the last things. 2. Elements of preference were pedestrian ways, pedestrian security facilities, various athletic facilities, and variety and high-class facilities in a play ground. 3. Satisfaction degree of differentiation elements of outdoor space was low not only in total complexes but also in each complex. As a result of analysis, these elements were not satisfied with residents. 4. Most of the differentiation elements of outdoor space in three apartment complexes, except planting traditional trees, were required to improve and maintain present condition. The cost to improve and maintain these elements able to pay by them was about 2.18 million won. Through this result, these elements were not options but prerequisites for planning outdoor space in apartment complexes. 5. In the future preference elements of differentiation of outdoor space in apartment complexes were pedestrian and jogging ways, places with water, various athletic places and facilities, multi-function resting places, green spaces in experiences, pedestrian security facilities, various athletic facilities, variety and high-class facilities in a play ground, and payment possibility for these elements was about 3.20 million won.

매 5년마다 시행되는 수도권가구통행실태조사결과에 대한 연구보고서가 발간되고 있지만, 아쉽게도 조사된 가구의 여러 속성들이 가구통행발생에 미치는 영향이 보다 면밀히 분석되지 못하고 있다. 본 논문은 가구 속성들이 통행발생에 미치는 영향을 비교, 분석하여 그 시사점을 제시하였다. 분석 결과는 향후 통행발생모형 등의 구축 시 중요한 기초가 자료가 될 것으로 판단된다. 먼저, 가구의 통행발생 추정 시 가구원수는 중요한 분류 기준으로 고려되어야 한다. 왜냐하면, 가구원수에 따라 승용차보유대수, 소득 등 가구속성들이 통행발생에 미치는 영향이 많은 차이가 있는 것으로 분석되었기 때문이다. 주중 통행실태 자료로는 충분하지는 않지만, 주택의 종류가 통행발생에 미치는 영향은 없는 것으로 분석되었다. 1인 가구의 경우 가구소득과 통행횟수는 관련이 없는 것으로 나타난 반면, 2인 이상 가구의 경우는 관련이 큰 것으로 분석되었다. 그러나 통행을 목적별로 더 세분화하였을 경우 가구원수에 따라 가구소득이 각 목적통행에 미치는 영향이 매우 다양함을 알 수 있었다. 특히, 향후 통행발생특성에 상대적으로 많은 차이를 보이는 1인 가구의 증가는 통행발생예측 시 간과될 수 없는 요인으로 판단된다.

The purpose of this study is to segment and examine urban farmers behavior by applying a two-step cluster analysis and multi-nominal logit model. The data were collected by a telephone survey with two-staged stratified random sampling in the cities around the country for the purpose of acquiring representative data. Respondents were asked to describe their awareness of urban agriculture, their agricultural activity, and sociodemographic characteristics. Among 2,000 cases, 381 cases(19.1%) which were of participants in urban agriculture were analysed in SPSS. From the findings, 27.3% of respondents had heard the word 'urban agriculture', and 25.5% of them regarded themselves as urban farmers. Four different clusters were derived from two-step clusters based on motive, place, companion, area and hours. They were 'Large scale hobby farming(cluster 1)', ‘Weekend farm/ hobby farming(cluster 2)', 'Land/ Self-supporting farming(cluster 3)', and 'Small scale hobby farming(cluster 4)'. The result of multinomial logistic regression showed that there were significant differences among these four segmented groups in terms of age, city size and housing type. In other words, there is quite a possibility that urbanites select different urban farming types according to their socio-demographic profiles. Therefore, the urbanite profiles can be used as the basis for promoting policy of several urban agriculture types. According to the result, policy directions for facilitating urban agriculture were presented.

This study was performed to investigate the awareness of an ecological city and its related variables and the willingness to move to an ecological city and its related variables. Data were collected through a questionnaire survey given to 491 residents in Mokpo, Kwangju and Muan in Chollanam Province. Awareness of the ecotogical city was medium level, half of the respondents were not aware of the ecological city. Multiple regression analysis was conducted to estimate the effects of the variables on the awareness of the ecological city. The most significant variable was environmental knowledge. Next, experience in environmental education and homeownership effected on the awareness of the ecological city. Those who knew about environmental pollution and environmental disruption had a self-reported higher degree of awareness of the ecological city. Those who had experience in environmental education as well as those who lived in their own house were more aware of the ecological city. Other variables were not statistically significant. Half of the respondents were willing to move to the ecological city. Seven variables were related with willingness to move to the ecological city. Those who knew about the environmental pollution and environmental disruption preferred to move to the ecological city. Those who lived in multi-housing had more of a willingness to move to the ecological city. People with a higher education as well as the younger group preferred to move to the ecological city. Those who were more aware of the ecological city and had more ecological-oriented values had more willingness to move to the ecological city. Salaried men and professionals were more willing to move to the ecological city than non-employed people. Among those variables environmental knowledge was the only influential variables on willingness to move to the city.

In this study, through the accumulated technologies such as real-time monitoring of power consumption using power line communication (PLC) method, power control, and automatic blocking of standby power, to commercialize them, we developed the hardware design, algorithm, protocol and module along with data transmission using PLC. We conducted the study to develop advanced products. We also proposed cloud-based smart outlet products with a novel type of outlet. These products can measure the internal power consumption through the H/W modules and the modules that control the power of household appliances connected to the smart outlets and smart plugs. Subsequently, they transmit the measurements to the energy saving system server via a communication module. This system can control the terminal device connected to the Gateway (G/W) server through a mobile phone. This will allow the customer to check the power consumption of the building at any given time, to turn the terminal on/off, and to maximize the energy efficiency during the construction of new apartments or multi-family housing in an area.

본 연구는 취약계층을 대상으로 건강정도를 객관적 지표인 체질량지수를 통해 비만 정도의 지역별 격차를 공간적으로 규명해보고자 한다. 따라서 체질량지수가 공간적으로 높은 값과 낮은 값을 가지는 군집패턴을 보이는 지역을 추출하고 이 지역의 특성을 분석하였다. 분석 결과, 비만인구비율의 I 통계량은 0.07, z-score은 4.39으로 나타나, 공간자기상관성을 확인하였다. z-score의 경우 최대 임계값인 2.57보다 훨씬 크게 나타났다. 이는 사회취약계층 비만율이 지역별 격차를 보이며, 이러한 격차가 공간통계적으로 유의함을 의미한다. 이러한 비만 취약지역과 양호지역에 대한 지역별 환경을 비교 분석한 결과는 취약지역의 경우 대중교통성이 좋지 않고 쉽게 이용할 수 있는 공원이 적으며 단독 다세대 주택이 밀집한 지역으로 확인되었다. 본 연구의 분석 결과는 기존 연구들이 소홀했던 사회취약계층의 건강에 대하여 공간적인 시사점을 제공한다는 점에서 의미를 지닌다.

Hospice is the wholistic caring service for terminally ill patient and his family so that he can live in dignity and maintain the quality of life until he passes away peacefully. The purpose of this study is to compare the development of hospice movement in UK, USA, Japan and Korea, to analyze space configuration characteristics of facilities built between 1980-2009 through case study. The result is as follows. First, The modern hospice started in England and it has spread around the world rapidly. In Korea, hospice service was introduced even prior to US and Japan and developed in spite of poor medical environment. The application of health insurance subsidies were late compared to other countries, but the hospice and palliative care system was quickly set on the basis of precedent cases. Second, the number of hospital beds per facility is decreasing, and it has been divided into smaller clusters for the residential atmosphere. The controversy between private rooms and multi-patient room is still ongoing, and increasing facilities without in-patient service. Rather than establishing uniform and absolute regulations, it is necessary to design a flexible space which can cope with various situations such as patients' needs, service changes, and manpower status. Third, the spaces for family members and friends to stay in both private rooms and communal spaces are increasing. Forth, Facilities for patients with different needs, such as children and adolescents and AIDS patients, have been developed in UK and USA. Further research on of patients' diverse needs and customized environmental support is necessary.

Background: This study was conducted to provide background information for the proper management of radon contamination in apartments using mechanical ventilation facilities in residential environments. Objectives: To this end, this study compared and evaluated changes in radon concentrations based on different operating intensities of mechanical ventilation with or without natural ventilation. Methods: For the continuous measurement of radon concentrations, an RAD7 instrument was installed in four apartments equipped with a ventilation system. The measurements were done for comparison of ventilation types and different ventilation intensities ("high", "middle", "low"). Results: The results confirmed that both mechanical and natural ventilation sufficiently reduced the radon concentration in the apartments. In particular, mechanical ventilation at "high" intensity was the most effective. Natural ventilation combined with mechanical ventilation and then natural ventilation alone were the second and the third most effective, respectively. Conclusions: When using ventilation to reduce indoor radon concentrations, it is most effective to operate mechanical ventilation ("high") or natural ventilation and mechanical ventilation at the same time. In cases where mechanical ventilation is available alone, it is recommended to operate it at a minimum of "middle" intensity.
