  • In this study, emission rates (ER) of biogenic volatile organic compounds (BVOCs) were measured by varying levels of photosynthetically active radiation (PAR). An appropriate plan for ozone reduction according to increasing ecology area ratio in future metropolitan areas was suggested. Several trees were selected as representative tree species in urban areas. Emission rates and composition ratios of monoterpene and isoprene emitted from these trees were estimated and compared. As a result, it was found that emission rates of BVOCs were considerably different depending on tree species. Especially, BVOCs emitted from Platanus orientalis and Quercus mongolica could significantly affect ozone increase in the metropolitan area, because the emission rates were several thousands to ten thousand times higher than those emitted from Zelkova serrata and Prunus serrulata. Furthermore, it was observed that emission rates of BVOCs by species increased maximum up to 10 times when PAR, which has close relations with temperature, rose. It was concluded that tree species such as Zelkova serrata et al., was appropriate for metropolitan areas since the species has low ozone potential and good landscape. Suppose this type of trees are planted on purpose in the urban areas, better ambient air quality will be promised in the future.

  • The purpose of this study is to give some suggestions for the legal supplement of the regulation on the balcony expansion for the optimal use of apartment balcony. For the purpose, this study focused on the characteristics of spaces expanded to the balcony, in the plans supplied after the legalization of balcony expansion, comparing them by their location; the metropolitan area of Seoul Gyeonggi and the districts of the other areas. The 168 plans of apartments in the supplied by top 10 constructors in the metropolitan areas of Seoul and Gyeonggi, together with the 92 plans in the other smaller districts in 2006 to 2007 were analyzed with the tools of frequency and chi-square analysis. The result is as follows. (1) The region showed no difference in the plans of balcony; whereas the size, the position and access of the shelter explained some differences of balcony plan. (2) In wider plans, balconies were placed in all sides of plan-front, rear and side, and were remodeled to expand facing rooms. (3) The balcony expansion tended to increase the number of bays. (4) In almost cases, the living rooms were expanded to balcony. In smaller plans, the balconies were remodeled to supply supplementary kitchen space, splitting it from laundry. (5) The shelters were placed at the rear or side of plans, but the shelter facing room could be dangerous in case of fire. The balcony expansion, despite of legalization spirit to adopt diverse use of additional spaces for residents' needs, was only a tool for the space expansion. The amendment of the regulation is needed to accommodate these findings that the balconies should be identified by their function, that the front corridor-type balcony should be limited in length and magnitude, and that the shelter should be positioned with easy access.

  • The purpose of this study was 1) to analyze the attitudes about Senior Congregate Housing(SCH) among 4 urban areas, 2) to propose the various model for SCH which should be provided to satisfy the demand. Same opinions among 4 urban areas were ; 1) Whom were willing to move into SCH for later life, most of them were in early 50s. Most of the respondents desired to be serviced community alarm system, preferred one-room style, size of 11∼15 Pyung, and preferred living at suburban area. The multi-family type was preferred when not being healthy and be singled, but if healthy, preferred the type of single detached house. And they preferred the home ownership, highly valued of heating control system, health care and leisure programs. Thus for the future SCH, it should be designed all facilities were equipped with sports facilities, sauna and leisure programs. The findings indicated that the high rates of supporting with professional management for 24 hours by turn. But different opinions among 4 urban areas were; 2) Willingness live in SCH for later life had little difference in level of income, education, property. Especially, residents of Seoul Metropolitan area and Busan did not want to open their own common facilities to the public.

  • 최근 들어, 산업뿐만이 아니라 사회 전반적으로 큰 영향을 미칠 것으로 예상되는 4차 산업 혁명에 대한 관심이 커지고 있다. 하지만 4차 산업의 공간적 분포와 관련한 연구는 제한적이었다. 이에 본 연구는 비지리적 방법인 LQ와 지리적 방법인 Getis-Ord's Gi*를 이용하여 4차 산업의 공간적 분포를 유형화하고 집적지를 도출하였다. 분석결과를 종합하면 다음과 같다. 첫째, 4차 산업의 "특화지역"은 수도권 지역의 비율이 높으나, 산업유형에 따라 비수도권 지역에서도 확인되었다. 둘째, 4차 산업의 "클러스터"와 "주변 지역"은 대부분 수도권에 군집하여 형성되어 있었다. 셋째, 수도권 지역 내에서도 4차 산업 "클러스터"는 과밀억제권역과 경기남부지역에 편중되어 나타났으며, 수도권 북부지역과 자연보전권역은 소외된 양상을 보였다. 본 논문은 4차 산업의 "클러스터" 지역이 수도권 지역에 집중되어 있으며 이러한 특징을 반영한 정책적 대안이 필요함을 보여주고 있다.

  • This study is to establish the Incheon Metropolitan City Arboretum Development Plan (IMADP) as a capacity building both for plant diversity conservation and nature friendly leisure activity areas of Incheon Metropolitan City, Korea. The arboretum planning area is located within territory of the Incheon Grand Park Based on the IMADP, the arboretum was divided into three display spaces; the Urban Greening Garden, the Rare and Endangered Plant Species Garden and the Theme Garden. Detailed planting guidelines were suggested according to the three garden areas. The Urban Greening Garden was designed to display the following three; the relevance techniques, the model, and the practical uses of plants that are regarded to an urban greening. The Rare and Endangered Plant Species Garden (REPSG) was planned for the collection and display of the rare and endangered native plants in the territories of Incheon and the island seashore. Also, the REPSG includes the education purposes of comparing and displaying taxonomically related plant species. The Theme Garden was projected for the collection and display of plant species that have long been familiar to Korean culture and which are also used in our daily life.

  • We present following research summary and implications through the analysis of the research. First, the before the opening of public cremation facilities compared to new opening of those, the number of the corpse cremation increases to annual average of 5.5% of the rate, and it has a positive effect on increasing rate of the cremation. Therefore, a policy of expanding the supply of public cremation facilities should be pursued to improve cremation rate in the area of uninstalled public cremation facilities. Second, the before the opening of public cremation facilities compared to new opening of those, the number of the corpse cremation has increased to the annual average 3,623 people(56.9%) at jurisdiction area, while it has decreased to 949 people (28.3%) at the out of the jurisdiction area. The active efforts and building the funding expansion should be made to establish public cremation facilities of the central and local governments to improve convenience of the use of public cremation facilities. Third, since the before and after opening of public cremation facilities at Jeongeup City lead to great effect on demand of jurisdiction area and out of the jurisdiction area, the cremation demand should be reduced through the supply expansion of public cremation facilities and differentiation strategy to control cremation demand at the out of the jurisdiction area, focusing on metropolitan areas with high cremation demand, such as metropolitan areas or metropolitan cities.
