Urban agriculture, which can be defined as agriculture performed in a city, is suggested as an alternative solution to restore deserted community and expand green land in city area through cultivation activities. In Korea, 'Urban Agriculture Promotion and Support Act' was enforced from May 2012. In addition, in the same year, Seoul Metropolitan Government declared 'the beginning of urban agriculture era,' established municipal ordinance, and increased budget to actively support urban agriculture. As a result, urban agriculture practices have been increasing every year. Yet, the way of developing urban agriculture in a uniform way of expanding green land has led to difficulties of securing proper spaces. Accordingly, 'roof top' spaces have gained attention. This study analyzes rooftop garden, one of the spaces of carrying out urban agriculture, from the publicness perspective. The study selected a case study of a public rooftop garden in Mullae-dong, Yeongdeungpo-gu, investigated present conditions and usage features of the garden, and explored the conditions to be a 'public' roof top garden. Through theoretical analysis, both physical and non-physical indicators were derived for analysis framework; physical aspects- accessibility, locality, openness, comfortness, and non-physical aspects- subjectivity, cooperativeness, and a sense of community. The results of this study are as follows. First, openness and locality scores were the highest, and comfortness scored the lowest, in ensuring the publicness of Mullae roof top garden. Second, non-physical indicators had stronger effect than physical indicators on rooftop garden users' awareness on publicness and building a garden community. In conclusion, in order to vitalize roof top garden, users should be engaged from the very first planning stage of building a garden, opening hours should not be limited, and more importance should be put on users to subjectively manage the operation of rooftop garden than merely creating a physical environment.

Full-scale ferro-concrete building technology came was introduced in Japan in Meiji $35{\sim}40(1902{\sim}1907)$ and heralding the beginning of urban modernization. On the roofs of these new architectural constructions, full-scale rooftop gardens were also developed. We consider that gardens established on the roofs of hotel and department stores created a new, modernized garden culture, which greatly influenced the early modern urban culture of Japan, the drama of which it conceived based on the impression in a rooftop garden is made. In this paper, we discuss the influence of Meiji-Era cultural and technological advances on rooftop gardens constructed during the Taisho $Era(1912{\sim}1926)$, as represented by the gardens of Kobe's Oriental Hotel, Tokyo's Mitsukoshi Department Store and Shimonoseki City's Akita Company. Photographic and print sources are utilized to analyze the design features and temporal changes of these pioneering rooftop gardens, as well as their influence on urban culture.

The purpose of this study, the type of rooftop learn more about the psychological benefits to users has been carried out, and healthy college students were examined in 40 patients. Conduct research to make the rooftop of the type of lawn, trees, ecological garden, wetland biotope, flowering plant in Seoul were divided into six groups. Measurement methods based on the type designation of the Planting and landscape photography by once the participants for each 10 minutes to watch and mood state tests (POMS) and the mean fractionation (SD), based on survey information about the psychological effects were correlated. Mood States test lawn, tree-oriented type, flowering plant stability in type, kindness, openness, and the effect of raising warme there was a tension, anxiety, depression, anger inhibition was effective. In contrast, depression and fatigue are common rooftop greening, respectively. The results in terms of the psychological effects of the type of rooftop garden ecology and wetland biotope than lawn, tree-oriented type, flowering plant types of users with a positive psychological effect seemed to be better.

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.

The objective of this study is to analysis the properties for reclassifying green roofs into three types by cluster analysis after investigating the present condition in thirty green roofs which were created from 2002 to 2004 by Seoul Metropolitan Government. The previous classification was resulted in structure safety diagnosis in the type of green roofs and visible judgment by experts in sites. However, it should have been corrected. Therefore, it needed a reestablished concept and a reclassification in green roofs. The results of this study are as follows : the concept of a rooftop garden and a green roof is different from previous studies. The rooftop gardens named by intensive green roofs are closed to integrated management, whereas the green roofs are closed to low management. The reclassification of green type was also conducted to use the statistic analysis of categorical regression by previous studies, and the factors extracted by the categorical regression were influenced by greening type. The figure of R-square representing explanation in regression analysis is 95.2%. As this result was analyzed, it was proved into rooftop gardens demanded for high activity by people.

This study was carried out to investigate the growth responses of medicinal plants such as Glehnia littoralis, Cryptotaenia japonica, Angelica gigas, Reynoutria japonica, Saururus chinensis, Houttuynia cordata, Ligularia fischeri, and Aralia cordata under 70%-shading and full sunlight conditions on a rooftop condition using artificial soil as a growth media. Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordata showed better growth on plant height, leaf length, leaf width, petiole length and leaf number under full sunlight conditions on a rooftop condition. Cryptotaenia japonica and Houttuynia cordata had high value of Hunter's a (red-green) under full sunlight, while had lower value of L(lightness) and b(blue-yellow) than those of 70% shading condition. As an index of plant stress response, Glehnia littoralis, Reynoutria japonica, Houttuynia cordata, Ligularia fischeri showed Fv/Fm values 0.79~0.84 under full sunlight in August, indicating low stress on plant growth. Therefore they seemed to be suitable medicinal plats for rooftop conditions. Ligularia fischeri and Reynoutria japonica showed better growth under 70% shading treatment in August, while showed high growth response under full sunlight conditions in September. The 70% shading treatment was effective for the growth of Angelica gigas, Reynoutria japonica, and Aralia cordata. Angelica gigas and Reynoutria japonica, however, showed better plant growth under full sunlight during summer. The results showed that Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordat seemed to be suitable medicinal plants for rooftop garden where there is a full sunlight condition.

Focusing on native plants that have a high possibility of being introduced as extensive rooftop material, this study was conducted to realize extensive and easy-to-manage rooftop gardens and to raise the utilization of native plants by verifying their growing response to soil media and depth. Its result is as follows: 1) In the case of Chrysanthemum zawadskii, the top growth was better in sandy loam than in P$_1$V$_1$P$_2$, and P$_1$V$_1$P$_3$, but the mortality rate was high, making it unsuitable soil. Regarding soil depth the mortality rate was lower in 10cm than in 5cm, and it grew well in 10cm. When using it for rooftop gardens, it would be desirable to keep the minimum viable soil depth over loom. 2) In the case of Sedium middendorffianum the mortality rate was 0% regardless of soil media and depth making it very suitable material for rooftop garden. Although the flowering rate was somewhat lower in P$_1$V$_1$P$_2$, and P$_1$V$_1$P$_3$ than in sandy loam, the mortality rate was low and the root growth was good. Therefore, provided that fertilizing is managed well, it is a plant that can be highly utilized. 3) In the case of Allium senescens, the mortality rate was 0% regardless of soil or soil depth, making it a very suitable plant for extensive rooftop gardens. Although top growth was poorer in P$_1$V$_1$P$_2$, and P$_1$V$_1$P$_3$than in sandy loam the root growth was good. Therefore, provided that fertilizing is managed well, it is a plant that can be highly utilized. In conclusion the study revealed that suitable species for extensive rooftop gardens are Sedium middendorffianum and Allium senescens. However, Chrysanthemum zawadskii can be utilized greatly when fertilizing is managed regularly in artificial mixed soil over l0cm.

Roof gardens/Rooftop farm are most often found in urban environments. Plants have the ability to reduce the overall heat absorption of the building which then reduces energy consumption. Plant surfaces however, as a result of transpiration do not rise more than $4-5^{\circ}C$ above the ambient and are sometimes cooler. As Urban agriculture in an accessible rooftop farm, space becomes available for localized small-scale urban agriculture, a source of local food production. An urban garden can supplement the diets of the community it feeds with fresh produce and provide a tangible tie to food production.
