Urbanization has caused increase of traffic jams, food shortage, housing, and environmental pollution in the world in recent decades. Urban agriculture, such as roof garden, can relieve the phenomenon of urban heat island causing from the urbanization. The study was conducted to investigate the characteristics of rooftop garden (farm) in 40 areas in Seoul, Korea, where the 'cabbage', 'lettuce', 'pepper', and 'mini-tomatoes' were the most preferred vegetables and fruit. The problems in the rooftop garden during a cultivation was observed for drainage system, soil management, cost or quality of planting mat and diseases and insects. The image of urban agriculture showed a positive words, such as 'bright', 'clean', 'open' and 'good' according to the survey.

도시농업의 기술 중 하나인 수경재배 농법은 공간의 물리적 제약이 다른 도시농업 활동에 비해 적고 재배환경을 어디든지 쉽게 구축할 수 있다는 장점이 있어 그 활용 가치가 높지만, 기존의 연구 대부분이 기술 개발에 초점 맞추어져 있어 도시민의 여가 문화적 가치를 내포하는 도시농업의 문화적 활용성 측면에서 연구가 부족하였다. 따라서, 본 연구는 수경재배를 활용한 도시농업 활동에서 학내 구성원이 인식하는 참여제약요인을 파악하고 도시농업 여가 향유의 관점에서 참여 의사결정에 영향을 미치는 변수 간 구조적 관계를 파악하였다. 근거이론과 선행연구 고찰을 통하여 수경재배 도시농업의 참여제약요인을 3가지 측면으로 나누고, 서울대학교 구성원을 대상으로 설문 조사를 수행한 후 R software를 활용하여 요인분석 및 구조모델에 대한 평가를 시행하였다. 그 결과로 첫째, 수경재배를 활용한 도시농업 활동에서의 참여제약요인은 크게 내재적 요인, 대인적 요인, 구조적 요인으로 나뉘었다. 둘째, 가설 모형 검증 결과로 대인적 제약이 참여자의 참여의지와 기대행동에 유의한 영향을 미치는 것으로 나타났다. 본 연구는 옥상이라는 도시공간에서 행해진 수경재배 도시농업에 대한 학내 구성원의 다원적 가치 인식을 파악하였으며, 연구 결과를 활용하여 도시공간이나 옥상에서 이루어지는 수경재배 도시농업 활동에 더 적극적 참여를 유도하는 전략에 근거를 제시할 수 있다.

This study investigated the effects of various planting models on the joint cultivation of eggplant (Solanum melongena) and marigold (Tagetes erecta)to enhance sustainable rooftop urban farming. Rooftop agriculture is increasingly valued to boost the food supply and benefit the environment. Integrating such practices into urban planning is viewed as a way to sustainably manage resources and improve the food-energy-water cycle in cities. The experiment was conducted on a rooftop in Chungju, South Korea from May to August. Four different planting setups were used: central eggplant with peripheral marigold (SET), eggplant with a protective net (SIC), central marigold with peripheral eggplant (TES), and control with only eggplant (CON S). These models tested the effects of companion planting versus monoculture using a lightweight soil mix ideal for rooftops made from cocopeat and perlite and enriched with organic fertilizer. Measurements focused on soil conditions and plant health and assessed soil temperature, moisture, conductivity, plant height, width, and leaf size. The results indicated that the SET modelyielded the best growth. This setup benefited from marigold pest control properties and its ability to improve soil conditions by enhancing moisture and nutrient levels and aiding eggplant growth. These findings underscore the potential of mixed planting on rooftops and suggest that such approaches can be effectively incorporated into urban agriculture to boost yield and environmental sustainability. This study supports the idea that diverse planting methods can significantly affect plant growth and promote urban greening and food security.

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.

This study was conducted to obtain basic data on efficient and eco-friendly crop cultivation for urban residents who enjoy urban agriculture as a hobby or leisure activity. We planted strawberry(Fragaria x ananassa)(S) and kidney bean (Phaseolus vulgaris var. humilis)(K) in different ratios to analyze the differences in soil environment, growth, physiology, and productivity, and to investigate the effects. Strawberry growth was optimal with S1K2 ratio, whereas the S1K1 ratio treatment showed the highest levels of physiology and productivity. In terms of growth and physiology, kidney beans tended to perform best in S1K2 treatment. The average number of productive pods was two, with a highest average value of 2.3 being recorded in S2K1 treatment planted with a high percentage of strawberries. In terms of growth, physiology, and prodctivity our findings indicate that it would be desirable to plant starwberries and kidney bean in a 1:1 ratio. However, considering the environmental characteristics of walls and rooftops, it is necessary to effectively manage crops suitable for these conditions. Furthermore, additional studies should be conducted to analyze the quality of fruits and seeds producted, both qualitatively and quantitatively in the future.

전통적으로 전력시스템은 공급체계의 말단에 있는 소비자의 위치에서 보면 중앙집중화된 구조를 갖고 있다. 그러나 최근 수 십년간 지붕형 태양광, 영농형 태양광, 소형 풍력터빈, 배터리저장장치 및 스마트 가전품과 같은 분산에너지원의 등장을 보아왔다. 분산에너지원의 등장에 따라 배전계통 운전원의 역할도 확장된다. 확장된 분산전원의 진출은 배전망이나 송전망의 전통적인 계획과 운영에 영향을 주는 전력계통의 역조류와 예측성을 어렵게 할 수 있다. 이는 전형적인 계통계획, 정비 및 망관리, 정전할당 등 배전계통 운전원이 갖는 기능이 변경되어야 할 필요성을 증폭시킨다. 이 연구의 목적은 다중 분산전원을 갖는 미래 배전운전시스템을 설계하고 제안된 배전시스템 모델을 HILS로 구현 및 검증하는 것이다. 시험결과를 보면 제안된 배전시스템이 정상 영역에서 운전되고 배전선로 손실이 감소된다는 것을 보여준다.
