  • In order to examine the effect of impermeable surface (rooftop, outdoor parking lot) and rainwater infiltration facilities on runoff pH, pH was measured. pH measurement spots were splash blocks accepted roof runoff of 3 sites, infiltration boxes and trenches accepted parking lot runoff and plastic rainwater harvesting facility accepted roof runoff. These measurements were operated at 3 housing complexes from 2006 to 2009. The rainwater runoff pH was influenced by the quality of the runoff surface material (concrete), the age of the building, waterproofing methods according to each housing site, antecedent rainfall conditions and others. Rain garden, infiltration boxes and trenches decreased the alkalinity of runoff by detention and infiltrating the roof and outdoor parking lot runoff. These results mean that decentralized rainwater management facilities of housing complexes can reduce effect on the outskirt aquatic ecosystem by the accumulation of substances causing pH rising in the infiltration facilities and rain garden.

  • Plants planted in the green-roofed areas in Busan and Jinju were surveyed. The woody plants investigated in this study were classified into 52 families and 156 species, and the herbaceous plants were classified into 30 families and 97 species. Woody plants mainly planted were Rhododendron yedoense var. poukhanense, R. indicum, C. kousa, P. mume, and E. alatus. However, Pinus spp. were planted in all areas. The main herbaceous species planted were Sedum kamtschaticum, S. takesimense, S. middendorffianum, T. quinquecostatus var. japonica, and A. spathulifolius Maxim. According to surveying the distribution of woody plant pests, they could be classified into six orders, 24 families, and 46 species that usually appeared from April to October but especially between June and September. We investigated 39 insect species in relation to pest damage to leaves, 21 insect species in relation to that of branches, and 39 insect species in relation to that of stems of woody plants.

  • This study was carried out to investigate the effects of soil depth and planting density on the growth of lettuce, crown daisy, and strawberry on a rooftop condition using artificial soil as a growth media. The vegetable crops showed better growth for plant height (cm), plant width (cm), plant fresh weight (g), and Fo, Fm and Fv/m on 20cm depth soil than 10cm depth soil except strawberry. Planting density of $16/m^2$ and $64/m^2$ did not show significant differences on the growth of the crops. Soil moisture content and EC were low for 10cm depth soil in lettuce plots, whereas there was no significant differences on soil moisture and EC between two soil depth in strawberry plots. Hunter's L, a, and b values showed the leaf color of lettuce dark green on 20cm depth soil and reddish on 10cm depth soil. Results showed that soil depth suitable for crop growth on rooftop conditions was 20cm rather than 10cm. Growth response of the crops showed no significant difference between $16/m^2$ and $64/m^2$, indicating that planting density of 64 $plants/m^2$ could be practiced on rooftop conditions. Lettuce growth rapidly changed in control treatment in which leaves were not pinched out, while slowly changed in plants which leaves were periodically pinched out. In the case of control plot, it was impossible to harvest because withering of lower leaves after blossom on June 22. The plant of crown daisy in which pinching was not conducted, blossomed on June 7, and the plants were removed since its aesthetical value was lost. Strawberry seemed to be a suitable vegetable crop for rooftop conditions based on its high covering rate and extended growth period until late October. The soil depth 20cm and planting density 64 $plants/m^2$ were suitable for vegetable crops on green roof system using artificial soil.

  • The purpose of this study is to understand what Le Corbuiser has intended on a panoramic landscape view through his modern architectural design. This paper is willing to improve that he considered both natural and local landscape scenery, when he designed architecture with drawing images. He designed various ways to see outside scenery and community culture through ribbon windows, piloti, architectural promenade, picture frame, and rooftop garden as the angle of view inside the building, 'designed landscape panorama' from his architecture. Therefore the contents of the study include the analysis of the local landscapes shown through his architecture by photograph, drawing of a real scenery, and his sketches with biology to find what he has intended. The following conclusions have three points. First, Le Corbuiser has a basic idea to bear a natural and local scenery from his architecture through five points of new architecture. Second, pilotis, ribbon windows, and roof garden with picture frame and architectural promenade are pathways of his architecture to see 'designed landscape panorama'. Third, it comes from his early architecture like Villa Savoye in 1920s to Couvent de Sainte Marie de la Tourette in 1950s, but Ronchamp church converts his idea on previous thoughts.

  • This study was carried out to analyze comparison of carbon storage and physicochemical properties of vegetation soil for extensive green rooftop established at Seoul National University in september 2013. For this study, 42 plots were made by 2 kinds of vegetation soil including A-type and B-type. A-type vegetation soil plots were made of 90% perlite and 10% humus and B-type vegetation soil plots were made of 60% perlite, 20% vermiculite, 10% coco peat and 10% humus. This study used 6 kinds of plants which are Aster koraiensis, Sedum takesimense, Zoysia japonica Steud, Euonymus japonica, Rhododendron indicum SWEET and Ligustrum obtusifolium. Field research was carried out in 11 months after planting. Physiochemical properties of B-type vegetation soil plots were better than A-type vegetation soil plots in every way and soil carbon content was also higher at B-type vegetation soil plots as well. B-type vegetation soil plots were maintained 10 to 20% higher soil water content than A-type vegetation soil plots of the study period. The species of herb which showed the best carbon storage was Zoysia japonica Steud at B-type vegetation soil plots. The species of shrub which showed the best carbon storage was Ligustrum obtusifolium at B-type vegetation soil plots. Plants generally showed better growth at B-type vegetation soil plots and B-type vegetation soil plots were higher than A-type vegetation soil plots in soil carbon stock.

  • This study evaluated the growth, physiological responses and productivity based on the intercropping ratio of cherry tomato (Lycopersicon esculentum L.) with basil (Ocimum basilicum L.). on the rooftops to determine out the efficient ratio in urban agriculture. From April to September 2019, an experiment was conducted on the rooftop of Konkuk University Glocal Campus. Cherry tomato and basil were selected as companion plants for eco-friendly urban agriculture on the rooftops. Each plot was created with a width of 100 cm, length of 100 cm, and height of 25 cm. After installing drainage and waterproof layers from bottom to top, substrate was laid out with a height of 20 cm. Intercropping ratio was consisted of a single tomato plant (TC), 2:1 tomato to basil (T2B1), 1:1 tomato to basil (T1B1), 1:2 tomato to basil 2 (T1B2), and a single basil plant (BC), were conducted using a randomized complete plot design with five treatments and three replication (a total 15 plots). Measurements were divided into growth, physiological responses, and productivity parameters, and detailed items were investigated and analyzed by classifying them into plant height, leaf length, leaf width, number of leaves, root length, root collar caliper, chlorophyll contents, fresh weight, dry weight, number of fruit, fruit caliper, fruit weight, and sugar content. Comparative analyses of cherry tomato with basil plants by intercropping ratio, growth, physiological, and productivity responses are determined to be efficient when the ratio of cherry tomato to basil ratio is 2:1 or 1:1.

  • This study investigates the physical characteristics of indoor rest zones using the Space Syntax Method. A conceptual framework is based on analysis of design works presented in competitions(544 rest zones of 24 buildings on 7 campuses). The analysis on the unit type of rest zones showed that they were mostly available as open type, followed by semi-open type and outdoor rest places. On the other hand, by classifying the shape of whole building into traffic lines and nodal points, it was found that the buildings with 3 or more traffic lines have lower availability than others, because the buildings required more nodal points along a little higher complexity and zoning formed at increased nodal points between building masses. The analysis on the location of rest zones on traffic lines showed that hall type was most excellent in the level of availability. Finally, the analysis on the floor height showed that hall-like open rest places and outdoor places like rooftop garden functioned as a factor to enhance the integration of different spaces. In conclusion, this research will help the follow-up studies make spatial creation planning that may enhance the spatial efficiency and availability of Indoor rest zones on the campus.

  • Recently, an increasing number of urban farmers are growing fresh vegetables and fruits themselves using urban garden or weekend farms. In other words, this is called urban agriculture. After the Industrial Revolution in the 18th century, the agricultural society changed from an agricultural society to an industrial society, and the population began to flock to the cities. With the continued increase of urban population, countries with abundant capital were able to control the distribution structure of food supplies and trade agreements among countries. Since energy consumption and carbon dioxide emissions caused by agricultural product movements have emerged as the main culprits of global warming, and our table is threatened by safety due to food supply that has no genetic modification or knowledge of the cultivation process, urban agriculture is already taking hold in the West. In other words, as agriculture met cities, its role grew. Each region actively conducts agricultural activities for raising poultry as well as growing vegetables and fruits by using flower beds of detached houses in the city center, rooftops of high and low buildings, or school playgrounds and small tributaries of land. The purpose of this study is to analyze and understand the significance and type of urban agriculture and to examine the cases of domestic and foreign urban agriculture based on this and to seek the developing direction of urban agriculture, which is gradually increasing. Tired of growing competition and rapid change, urbanites are seeking health and relaxation and are planning to present development measures for urban farming and conduct follow-up research to ensure safe food.

  • 본 연구는 전문가와 일반인 집단 사이의 정원과 공원에 대한 인식 차이를 규명하기 위해 수행되었다. 설문을 통해 정원의 영역과 규모, 예술성과 과학성, 공공성, 실용성과 심미성, 조성 및 관리 주체, 주재료 등을 조사하였으며, 아울러 수목원정원법과 도시공원법에 대한 이해도를 규명하고자 하였다. 문헌연구를 통해 정원과 공원의 속성을 도출한 후 전문가와 일반인에게 각각 설문조사를 통해 정원과 공원의 개념, 유사성, 차이점 등을 각각 분석하였다. 정원 및 공원의 범위에 대해서는 전문가 그룹이 일반인 그룹에 비해 더 넓게 인식하고 있는 것으로 나타났다. 공통적으로 정원으로 인식한 공간은 옥상녹지이며, 도시숲은 공원으로 인식하고 있었다. 또한, 일반인 그룹은 도시숲을 정원으로도 인식하고 공원으로도 인식하여 구분이 명확하지 않았다. 전문가 그룹에서 정원은 소규모이고 공원은 대규모라는 인식이 더 우세했다. 대체로 정원은 개인공간이고 공원은 공공공간이라는 인식이 많게 나타났으며, 전문가 그룹에서 정원은 개인적이고 공원은 공공성이라는 인식이 더 우세했다. 일반인 집단은 전문가 집단에 비해 정원과 공원 모두 근소하게나마 예술적 창의성보다 기능적 과학성이 더 강조된 것으로 나타났다. 또한, 일반인과 전문가 모두에게서 대체로 정원보다는 공원이 예술성과 과학성을 아우르는 복합성을 띠고 있다고 인식하고 있는 것으로 나타났다. 정원은 식물재료가 중심이 되며, 공원은 조형물 시설물이 중심이 되거나 식물재료와 조형물 시설물이 적절히 균형을 이루는 공간으로 인식하고 있었고, 전문가 집단에 비해 일반인 집단에서 정원은 식물재료 중심이며, 공원은 시설물/조형물 중심이라는 시각이 매우 높게 나타났다. 전문가 집단은 정원의 심미성을 더 강조하고 공원에 대해서는 실용성을 더 인식하고 있었으며, 일반인 집단은 정원과 공원의 실용성과 심미성에 대한 인식이 유사하게 나타났다. 또한, 일반인 집단에서 정원의 실용성이 공원의 심미성이 더 강조되어 상대적으로 공원에 대한 심미성을 더 인식하고 있는 것으로 나타났다. 조성 주체에 대해 정원은 민간부문으로, 공원은 공공부문으로 인식하고 있었으며, 그 차이는 전문가집단에서 더 크게 나타났다. 관리주체에 대해 전문가와 일반인 모두 공원이나 정원의 관리는 조성 주체가 수행해야 하는 것으로 인식하고 있어, 관리주체의 다양화에 대한 논의가 필요한 것으로 나타났다. 이와 같이 전문가 그룹과 일반인 그룹에서 정원과 공원 개념의 혼재와 더불어 일정한 인식의 차이가 있음을 알 수 있었고, 법적 제도와 인식에서도 아직은 큰 차이가 있는 것으로 나타났다.
