  • 재활용 제품의 사용이 증가함에 따라 이에 대한 위해성 평가가 필요한 실정이다. 본 연구에서는 재활용 제품 중 재활용 고무분말을 이용한 놀이터용 바닥재와 해당 고무분말의 중금속 함량을 비교하였다. 또한 각각의 물질이 경피로 전이되는 양을 확인하여 피부에 흡수되는 중금속 노출 특성을 살펴보았다. 아연의 경우 함량이 높은데 반해 전이량이 0.1 $mg/cm^2$으로 매우 낮았는데 이는 아연은 표면 접촉으로는 잘 묻어나지 않는다는 것을 나타낸다. 그러나 철과 알루미늄의 경우, 함량이 바닥재에서 12 배 높게 나타났고, 전이량이 아연보다 약 5 배 높게 나타났다. 이것은 철과 알루미늄이 바닥재에 사용된 안료에서 기인했다는 것을 말한다. 놀이터 6 개소를 대상으로 피부 흡수에 의한 중금속 노출량을 산정한 결과, Ba의 경우 타 중금속에 비하여 비교적 높게 산정되었다. Zn의 함량이 높음에도 불구하고 Ba의 노출량이 더 높은 것은 Ba의 피부흡수율이 Zn에 비해 약 5 배 높기 때문인 것으로 판단된다.

  • This is on-going project planned from June to August, 2003 for the development of sub-urban housing of 108 buildings on 30,000 pyung lot located in Dochuk-myun, Kwangju-si, Kyunggi-do. The Site is consist of 10 different building sizes ranging from 45pyung to 65pyung on 180 to 220pyung lot. Buyers can customize their types and functions based on given sizes. Most sub-urban housing until now was based on typical planning and had no regard for its characteristics of diverse location. To solve these problems, I designed each types according to its locational characteristics and gave each lot flexible shape to have identities. To take advantage of its undulation, I put playground and sports facilities like swimming pool and tennis court at the approach. Central square to the center and park and observatory to the top

  • The purpose of this study was to analyze the relationship between outdoor play environments and child's play behaviors. The data were collected by field measurement survey, and non-participatory observation from 9 child care centers in Daejeon. The field measurement survey were conducted from June 20 to July 20, 2004, whereas non-participatory behavior observation were conducted from September 2 to October 10, 2004. The major results showed the following. 1) The characteristics of outdoor play environment in child care centers showed that most of them were too small and did not use the adequate surfacing to play various activities. In many cases, outdoor play settings was made of play equipment setting, play props and manipulative settings, and tree/vegetation. 2) Child's play behavior has been focused on functional play activity and construction play activity. 3) The relationship between outdoor play environments and child's play behaviors showed that small outside play environment with monotonous construction and multi-complex play equipments produced functional play behaviors on children. On the other hand, where various play areas were put together, we could observe relatively diverse play behaviors. However, in some cases, despite the small and monotonous play area, diverse play behaviors were observed. These playgrounds at least differed from others in that they provided the place where multi purpose play was possible. This finding shows that multi purpose play areas can be an alternative in small playground environment.

  • The purpose of this study was to analyze the usage characteristics and the role of spatial and social psychology of open spaces in urban neighborhoods. The survey for this study was conducted on 318 residents in Gyungsan. For analysis, the frequencies and means were calculated, the chi-square test, t-test, and analysis of variance were performed. Survey results revealed that, first, not only the preferred open space type but also the usage characteristics by gender were different. The tendency for males was to visit open spaces to exercise and to stay for longer than one hour. However, the females visited open spaces to care for their children and meet friends or neighbors. They also visited more often than males but stayed for a shorter time. Second, females tended to consider the open space as a place for rest and leisure. Females valued the social psychology aspects of the open space function. Third, regarding the spacial role of open space in urban neighborhoods, study participants believed that the waterside parks improve the quality of life, but were concerned for the safety of children. Considering the social psychology role of open spaces, study participants regarded the waterside parks as improving emotional health. Particularly, they believed the waterside parks played a greater role in daily life as a place for meeting, resting, and leisure than other open space types such as playground, children's parks, and sport parks.

  • In this paper, the relationships between volumetric mixing ratio of rubber chip and physical and mechanical properties of wood/rubber composite panel was examined in order to investigate the mixture characteristics of wood and rubber chip. Because of the specific gravity of rubber differed from wood chip, physical properties of wood/rubber composite panel was shown very different values by mixing rate of chip element. Specific gravity in air-dry of composite panel was increased rapidly as volumetric percent of rubber chip was increased. Moisture content of composite panel was decreased as volumetric percent of rubber chip element was increased. This results was considered that wood weight is light and porosity material for moisture absorption. Compressive strength and modulus of rupture in bending test were decreased as volumetric percent of rubber chip increased. By mixing ratio control of chip elements, various wood/rubber composite panel can be applicable to every interior materials such as subfloor, playground, and exterior materials such as road blocks for recreational facilities in garden and forest and city parks.

  • The purpose of this study was to examine the residents' opinions on the degree of importance, and satisfaction with, the managerial service of multi-family housing. Residents' participation in managerial activities was also examined, because residents' opinions should be taken into serious consideration in order to improve the efficiency of housing management. Research methods used in this study were survey, field study, and content analysis of professionals' opinions. Survey data of 520 residents who live in multi-family housing were analyzed by means, frequencies, correlation, chi-square tests, t-tests, one-way ANOVA, post-hoc estimation (Scheffee test), and regression. The major findings of this study were as follows: First, many residents were dissatisfied with the quality of managerial service, but they thought that managerial services were very important. For example, they thought that safety inspection of the playground was very important, yet the current level of service was not satisfactory. Second, the characteristics of residents that determined the degree of residential satisfaction were income the location of the residence, and degree of participation in the community events. Third, the residents generally did not want to participate in the managerial services and community programs through such activities as participation in resident committee. In order to improve the housing management efficiency, residents' participation is critical. Some participants in this study pointed out that the details of management service and future plans need to be made public. New management models need to be developed to promote residents' participation and increase their satisfaction in the management.
