The objective of this study is to suggest basic data for establishing future urban agriculture vitalization policies, by analyzing the preference of urban agriculture types in accordance with lifestyle as the standard of living for urban residents is improved. A survey was conducted targeting residents of nine autonomous regions that have established grounds for supporting the urban agriculture vitalization by enacting an urban agriculture ordinance, among 25 autonomous regions of Seoul. It aimed to verify a causal relationship between lifestyle and preferred activity of urban agriculture. In the results of the study first, a 'Health pursuit-type' was significant within the 'urban type' urban agriculture. These urban residents, pursuing safe food and health, actively participated in urban agriculture educational programs, and also preferred urban agricultural activities such as planting plants, landscape crops for the improvement of natural scenery in the downtown, and also participating in urban agriculture fairs. Second, 'Leisure activity-type' was significant with the 'House advantage type' urban agriculture. Urban residents mostly emphasizing hobby and leisure activities preferred the 'House advantage type' urban agricultural activities such as tending a vegetable garden in indoor life or using the veranda space of an apartment. Third, 'Health pursuit-type' was significant with the 'Schooling type' urban agriculture and 'Farm and Park type' urban agriculture. Urban residents pursuing health preferred tending an educational-type vegetable garden and educational farm connected to schools, running private farms outside of the downtown, and actively participating in urban agriculture park. Fourth, 'The neighborhood type' was significant with the 'Schooling type' urban agriculture. 'The neighborhood type' urban residents preferred actively participating in diverse urban agriculture education activities. The significance of this study is to examine the tendency and preferred activities of end users of urban agriculture by suggesting the necessity of viewing urban agriculture from the aspect of a consumer, and then examining the influential relationship between lifestyle and preference of urban agriculture-types.
This study was conducted to analyze the factors influencing participation intention in urban agriculture. The theoretical foundations of the study were Theory of Planned Behavior (TPB) and Pine and Gilmore's Experiencel Economy. The type of household composition was set as the moderating variable between these independent and dependent variables. In order to test the research model, hierarchical regression analysis was conducted on 439 effective respondents. The empirical analysis results are as follows. Educational experience factors, escapist experience factors, attitudes, subjective norm, and perceived behavioral control, which were set as independent variables to positive (+) influence participation intention in urban agriculture. In addition, the impact of their influence relationship was as follows : perceived behavioral control > attitudes > escapist experience factor > subjective norm > educational experience factor. On the other hand, as a result of analyzing the moderating effect according to the household composition, there was a significant difference in the effect of educational experiences, escapist experiences, and subjective norm on participation intention in urban agriculture. Significant results were not tested on the moderating effects between attitudes, perceived behavioral control, and participation intention in urban agriculture. Based on the results of this empirical analysis, academic and practical implications were presented.

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.
The purpose of this study is to segment and examine urban farmers behavior by applying a two-step cluster analysis and multi-nominal logit model. The data were collected by a telephone survey with two-staged stratified random sampling in the cities around the country for the purpose of acquiring representative data. Respondents were asked to describe their awareness of urban agriculture, their agricultural activity, and sociodemographic characteristics. Among 2,000 cases, 381 cases(19.1%) which were of participants in urban agriculture were analysed in SPSS. From the findings, 27.3% of respondents had heard the word 'urban agriculture', and 25.5% of them regarded themselves as urban farmers. Four different clusters were derived from two-step clusters based on motive, place, companion, area and hours. They were 'Large scale hobby farming(cluster 1)', ‘Weekend farm/ hobby farming(cluster 2)', 'Land/ Self-supporting farming(cluster 3)', and 'Small scale hobby farming(cluster 4)'. The result of multinomial logistic regression showed that there were significant differences among these four segmented groups in terms of age, city size and housing type. In other words, there is quite a possibility that urbanites select different urban farming types according to their socio-demographic profiles. Therefore, the urbanite profiles can be used as the basis for promoting policy of several urban agriculture types. According to the result, policy directions for facilitating urban agriculture were presented.

This study is carried out to find the most optimal soil-plant combination in the urban agriculture by analyzing the association of soil base material which is being used in the urban agriculture with the growth of plants. 4 types of easily purchased soil (bed soil(A), animal vermicast soil(B), earth worm soil(C) and matured compost(D)) verified in aspects of effect and safety of soil in terms of growth of crop is selected as experimental soil and B, C, D type soils are mixed with granite soil at the ratio of 7 : 3. And granite soil(E) is set as a controlled soil and is compared to verify the effect of the experimental mixed soil. Herbaceous plants are classified into the fruit vegetables (Lycopersicon esculentum Mill. and Capsicum annuum L.), leafy vegetables (Brassica campestris L. ssp. Pekinensis and Lactuca sativa L.), medicinal vegetables (Chrysanthemum zawadskii var. latilobum and Liriope platyphylla F. T. Wang & T. Tang). The results of comparison of growth of herbaceous plants in different soil types showed that fruit vegetables and leafy vegetables in general had excellent growth in D type soil mixture and A type soil in general and had the poorest growth in E type (controlled) soil. 'Chrysanthemum zawadskii var. latilobum' had the excellent growth in D type, B type, C type mixed soil and A type soil and E type (controlled) soil are followed in order. In the case of 'Liriope platyphylla F. T. Wang & T. Tang', the difference in growth by each soil was shown to be insignificant. Therefore, the soil applied in the urban agriculture varies depending on each species of herbaceous plants, but it is considered effective to cultivate herbaceous plant which is economical and productive by using D type mixed soil which can be recycled and inexpensive compared with other experimental soils in the urban agriculture.

This study was conducted to find out differences in the removal efficiency of particulate matter (PM) depending on the type of plants and the morphological characteristics of leaves. A total of 12 plants were used, with three plants selected for each type of leaves (big leaf, small leaf, compound leaf, needle leaf). We measured the removed amount of PM10 and PM2.5, the structure of the abaxial leaf surface, and the weight of the wax layer of each plant. Plants with the high removal efficiency of PM included Pachira aquatica Aubl., Ardisia crenata, and Dieffenbachia 'Marianne', and plants with the low removal efficiency included Nandina domestica Thunb, Schefflera arboricola, and Quercus dentata. The abaxial leaf surface having a high removal efficiency of PM had many large wrinkles, and the abaxial leaf surface having a medium removal efficiency was flat and smooth. On the other hand, there were many fine hairs on the abaxial leaf surface with a low removal efficiency. According to the plant leaf type, the PM10 removal efficiency of plants with needle leaves was about three times higher than that of other plants. In particular, the wax layer of conifers weighed 6-24 times higher than those of other plants. The stomata of conifers were evenly distributed on the adaxial and abaxial leaf surfaces; however, the stomata of Sciadopitys verticillata appeared in the form of papillae unlike general stomata. Therefore, the removal efficiency of PM varied depending on the macro-, and micro-morphological characteristics of plant leaves such as the structure of the abaxial leaf surface, and the weight of the wax layer. Based on this research, selecting plants that are effective in reducing PM in consideration of the plant type and leaf characteristics will improve indoor air quality and decrease exposure of PM to human body.
Background and objective: Urbanization caused a reduction in urban green space and a lack of community spaces. An attempt to solve these problems, urban gardens, have become popular and are currently being implemented in various downtown areas. However, urban gardens have some inadequate aspects from a visual or landscape perspective. The goal of this study was to examine the possibility of an aesthetic and productive garden space by introducing cultivation methods through the planting system design process. Methods: The design process using plants was classified and presented to suggest the importance of the landscape and aesthetic value. An urban garden space was designed according to the perspective of 'production scenery' and 'participation aesthetics'. According to the characteristics of the plant, urban gardens were divided into vertical type (corn, millet, sorghum), climbing type (kidney bean, cucumber, bitter gourd), and runner type (melon, watermelon, peanut). After classifying plants according to the shape of the root, the structure supporting climbing was installed and the crops were cultivated in an upright form with a tunnel. Results: In the designed cultivation, each crop cooperates, without invading each other's space. Compared with the conventional cultivation, there was little difference in production, and management was made more convenient since weed outbreaks were effectively suppressed while runner type crops cover over the land's surface. Since the positions of each crop are clearly distinguished, the aesthetic value is improved by offering a sense of rhythm with a balanced design. Conclusion: The results suggest that the cultivation methods through the plant system design process have aesthetic as well as productive value, and the design using plants, an infinite living resource, could lead to an expansion of the design field. Moreover, it would enable a sustainable symbiosis between industry and environment. There is potential for the design industry to make significant progress through collaboration with agriculture, horticulture, and landscape architecture.

This study was developed to investigate the effects of privately owned public space (POPS) on urban streetscape and to find ways to prevent the discontinuation of street continuity on urban landscape when creating POPS in urban space and the surrounding streets. Several case studies and policies and laws related to POPS were reviewed to identify the practical problems as well as current state. An additional analysis was conducted on the different types of POPS to examine spatial connections between them and streetscapes and to find ways to improve POPS on urban streetscape. Our results show that POPS surrounding a building (i.e. frontage space and adjacent sidewalks) should be considered as one space in the integrated perspective. In addition, the type of facilities installed on POPS would be decided according to whether POPS is recognized as the part of public rest area or treated as the part of street. The results of the study will serve as useful data to solve the current problems with city's POPS, which destroys spatial continuity by focusing on increasing the number of POPS and creates high-rise buildings isolated from existing spaces. This study will also contribute to improve the quality of future POPS.

The characteristics of $CO_2$ exchange between plant and human modules, absorption rate of NO$_2$, and growth of lettuce were examined in an urban-type plant factory(UPF). With 150 lettuce plants, $CO_2$ concentrations of plant module were 600 ~ 700$\mu$mol mol$^{-1}$ at average leaf weight of 130g.plant$^{-1}$ and 900~1100$\mu$mol.mol$^{-1}$ at 75g.plant$^{-1}$ for one and two persons' stay in the human module, respectively. When the air of 0.13, 0.30 and 0.45 $\mu$molㆍmol$^{-1}$ NO$_2$ in a human module was circulated ON/OFF 10/20min between the human and plant modules, $NO_2$ decrement in the chamber during 10 min was 0.040, 0.109, and 0.149 $\mu$mol, respectively. The lettuces grown at 0.45 $\mu$molㆍmol$^{-1}$$NO_2$ during experimental period showed no significant differences in growth factors such as leaf width, leaf length, leaf area and fresh weigh, and in the quality between treated and control.

This study analyzed the situation of urban agriculture development through theories, paradigms, and typology to determine the application frequency and development keywords about space forming. The results showed that urban space by distance determines "Dimension of space forming" through self-production, public-production, and nation-social operation. Second, the complex space by shape determine "Identity of space forming" through "Flat Shape" for using the widespread land, "Compact Shape" for overcoming the small and poor land, and "Fusion of Flat Compact Shape" for systematic use between Flat and Compact. Third, building and interior space according to location determine the "Utility of space forming" through land, roof, wall, veranda, interior, and infrastructure space. The concepts about space forming of urban agriculture have an organic correlation and will be developed sustainably by the evolved cases from now on. In addition, space forming of urban agriculture produces new creation space by various fusion processes and will be a development trend of new urban agriculture.
