본 연구에서는 고밀 시가화지역 내 녹지들의 경관생태학적 특성과 연결성을 분석함으로써 잠재적인 녹지패치들의 활용가능성을 평가하고, 이를 통해 생활권 내 녹지 네트워크를 형성하기 위한 도시정원의 도입 방안을 제시하고자 한다. 이를 위해, 서울시에서 공원 서비스 소외지역 및 중점녹화지구로 분류된 역삼동 일대를 대상지로 선정하였다. 우선, 대상지 일대 고밀 시가화지역 내 녹지의 현황을 가로녹지, 개인정원, 자투리공지, 공원, 옥상정원의 5개 항목으로 분류하여 파악하고, 녹지 네트워크 분석 및 잠재적 녹지의 가치를 평가하기 위하여 FRAGSTATS를 통한 경관지수 분석 및 다중버퍼생성분석을 통한 연결성평가를 실시하였다. 연구결과, 대상지 내 녹지면적은 가로녹지, 개인정원, 자투리공지, 공원, 옥상정원의 순으로 분포되어 있었다. 녹지의 유형별 특징으로는 가로녹지의 경우 핵심지역면적(TCA)이 $1,618m^2$로 가장 높은 값을 보여 선형 연결 녹지임에도 공원($1,128m^2$)에 상응하는 크기를 보였고, 개인정원의 경우 패치의 모양이 불규칙하면서도(ED=78.1m/ha), 최근린 평균거리가 33.9m로 낮아 사유지내에서의 자유로운 정원조성을 통해 고밀 시가화지역의 녹지군을 형성할 수 있음을 나타내었다. 자투리공지의 경우 대상지 내 가장 고루 분포하는(LPI=5.7%, SHEI=0.9) 녹지유형이나 외부교란에 노출되어 있어($TCA=66m^2$), 이를 고려한 정원으로의 활용방안을 시사하였다. 대상지 내 녹지네트워크 형성에 있어서도 50m의 버퍼 범위를 연결녹지로 상정한 경우 전체 대상지의 84%가 소규모 녹지네트워크에 의해 커버되는 것으로 나타났으며, 자투리공지의 연결만으로도(27%) 가로녹지(26%) 조성에 상응하는 네트워크 구축효과가 기대되었다. 이에, 주택지역을 중심으로 다양한 활동이 가능한 자투리 공공녹지에 지역기반의 커뮤니티 가든 등 도시정원 조성을 장려하고, 가로녹지, 개인정원, 옥상정원도 동시에 적극 활용함으로써 고밀 시가화지역 내에 녹지네트워크를 효과적으로 구축할 수 있다고 판단되었다.

The purpose of this study is to prepare a plan for improving the bird habitat environment of Linear Park. To this end, after grasping the status of bird habitats on the Gyeongchun Line Forest Road, a representative linear park in Seoul, the habitat environment was evaluated and the correlation with the bird habitat was analyzed to derive a plan to improve the habitat environment. The results for correlation between diversity of birds and habitat environment were as follows. For the habitat environment inside the park, the order of positive correlation was in the order of park area (0.92), number of insect species (0.87), green area ratio (0.77), average width of linear park (0.74), Biotope area ratio (0.73), Immigration planted species (0.57). Also, for habitat environment outside the park, the bird diversity was influenced in the order of area outside the park (0.88), green area ratio of the park (0.76). Thus, in order to enhance the diversity of birds found in the park, the bird habitat environment inside the park needs to expand the park area, secure insect diversity, enhance green area ratio and ecological area ratio, expand the width of linear park, and lower the impermeable layer. For the bird habitat environment outside the park, wider area, green area ratio, and forest area of the park influenced on better bird habitation while lower ratio of road space and building-to-land ratio influenced on higher bird diversity. It is necessary to create an environment inhabitable for various species of birds and to make a healthy and pleasant city urban system for co-existence of human and living creatures.

The impermeable area on the surface of city has been increased as buildings and artificial landcover have continually been increased. Urban development has gradually decreased the green zone in downtown and alienated the city from the natural environment on outskirt area devastating the natural eco system. There arise the environmental problems peculiar to city including urban heat island phenomenon, urban flood, air pollution and urban desertification. As one of urban plans to solve such problems, green roof system is attracting attentions. The purpose of this study was to investigate the heat reduction effect according to the development of green roof system and to quantify the heat reduction effect by analyzing through simulation the heat environment before and after green roof system. For thermal environment analysis, Thermo-Render 3.0 was used that was developed by Tokyo Industrial College to simulate. The simulation showed that the heat island index before and after the development of tree-planting on rooftop changed maximum $0.86^{\circ}C$ and the surface temperature changed about $20^{\circ}C$. Only with lawn planting, heat reduction effect was great and it means that the green roof system in low-management-light-weight type is enough to see effect. The simulation identified that only lawn planting for green rooftop brought such difference and could lower the heat island index at a narrow area. It is judged that application of green roof system to wider areas might relieve urban heat island phenomenon positively.

본 연구에서는 1973년 완공된 소양호에 처음으로 발생한 녹조현상에 대하여 위성영상을 사용하여 분석하였다. 연구자료는 2023년 7월부터 약 2개월간의 광학영상 13장을 사용하였으며, 소양호에 발생한 녹조의 면적을 산출하였다. 정확한 녹조 발생 면적을 산출하기 위하여 support vector machine 알고리즘 기반으로 영상분류를 수행하였다. 그 결과 소양호의 녹조는 녹조 발생을 유발하게 한 불순물이 유입된 지점을 중심으로 발생하였다. 2023년 8월 태풍 카눈의 효과로 일시적으로 감소하는 듯 보였으나 지속된 더위로 인해 다시 녹조가 증가하였다. 본 연구결과는 소양호는 수도권 주요 수원지 중 하나로 반복적인 녹조 발생을 대비해야 하는 점을 시사한다.

As a result, 34 species, 7 blue-green, 14 red, 6 brown and 7 green algae were identified as a summer flora from the area. Among them, Sirocoleum kurzii (blue-green alga), Ralfsia clavata (brown alga), Pseudulvella consociata and Cladophora speciosa (green algae) were known as new records to Korea.

The dependences of color gamut size and power consumption on the area ratio of the neutral and green subpixels for the RGB-LED-backlight RGBW LCD were studied, in which the red- and blue-subpixel areas are the same and represent one-quarter of the pixel aperture area. It was found that the color saturation of the RGBW LCD can be improved through the use of a smaller neutral- and green-subpixel area ratio, at the expense of higher power consumption.

Green roof in Korea has been recognized as part of landscape area and local governments enacted municipal ordinance for supporting green roof thereby assisting part of expenses spent for green roof within a range of budget for buildings which are eligible for the green roof support of existing buildings. However, it is necessary to enforce a regulation of mandatory green roof for new buildings in order to expand green roof application and provide a variety of assistances such as subsidy payment, tax relief, and mitigation of floor area ratio-related regulation as done in other advanced nations. In particular, LEED(Leadership in Environmental and Energy Design) in the USA applies additional point directly for green roof in terms of the reduction in heat island effects. For example, the following items are beneficial to have additional points: habitat preservation or restoration, external space, rainwater management, reduction in outdoor water usage, minimum energy performance, and optimum energy performance. In addition, the BREEAM(Building Research Establishment Environmental Assessment Method) in the UK specifies green roof as one of assessment items to be complied in terms of diversity of species. As such, LEED and BREEAM reflect direct and indirect effects of green roof on assessment criteria, which suggest a direction to green building certification criteria in Korea where only additional points are given for green roof according to soil depth.

In this Study, effect of core position, area ratio and orientation of building on energy load is examined using TRNSYS17. This parameters are major parameters of the conceptual design stage. Reference model is square floor plan($1,444m^2$), centered core and 29% core area ratio. As the results, without considering the building orientation, the annual heating load of central building with 1:1 area ratio is lowest ($10.33kWh/m^2yr$) and the annual cooling load of off-central building with 1:1 area ratio is lowest ($59.27kWh/m^2yr$). As area ratio is bigger, cooling load is lower and heating load is higher. But if we consider building orientation, orders of heating load and cooling load are changed for area ratio and orientation.

The purpose of this research was to elucidate the relevance of the area of home economics in practical arts (technology & home economics) curriculum to green growth education, finding applicable cases of green growth education content in the field of home economics education. Given this base, we performed a survey with people who majored in home economics education and elementary school teachers on how green growth education related to their education. We studied applied cases and performed a survey by open-ended questions that extracts the green growth education content. In synthesizing the results of these studies so far, we have concluded that home economics education is much related to green growth education, and that with a change of people's conceptions when relating school life to household life, home economics can be a very useful subject that can lead to the practice of the green growth education.
