Recent urban sprawl has destroyed various kinds of green space in tile city. It has affected duality of people's life in the city, as well as urban ecosystem. Recent study shows the possibilities of roofs as green spaces in urban central site where the land costs are generally high. This research focuses on Jung-Gu district in Daegu Metropolitan city as a study area and calculates possible area of green roof using 2002 Autocad program based on aerial photographs and land registration maps. And the purpose of this research is to analyze environmental and economic effects of green roof. The environmental effects are as follows. It is expected that $91,106m^2$ green spaces, 12.13 % of study site, will be added if green roof is performed in the study site. It is assumed that the expanded areas could reduce the highest temperature to $0.5-1.0^{\circ}C$ during the summer in terms of environmental effect. And the following shows the economic effects. If green roof and greening urban central site are created as a same size of $91,106m^2$, it will be expected that the costs of green roof will be much more in-expensive than about 98 billions won. It will be also found that the expense of cooling energy can be saved out about 8 millions won per day in summer, if grass planting is accomplished on the possible areas of green roof in the study site. Therefore, it is desirable to take legal supports such as enacting regulations to activate green roof for more environmental and economic effects. For instance, green roof for public institutions, school and model area selection are desirable method to publicize the effect of greening program for citizen's participation.

Like other organic beings, modern cities change every day. Unlike in the past, changes of space which have been taking place in concentrated spaces during short periods of time have worsened the environment of cities creating environmental problems. In particular, the urban heat-island phenomenon, which is caused by changes in using the earth's surface, has emerged as a key social issue along with health problems and economic difficulties. The Green Network has been introduced as an urban planning approach to solve the urban heat-island phenomenon. This study suggests constructing a Green Network through analyzing the urban heat island phenomenon, land cover classification, and linkage possibility with the Green Network and wind corridors by researching Jung-Gu, and Nam-Gu in Daegu Metropolitan City. In conclusion, this study presented the construction of a broad and detailed Green Network of object areas by assigning Apsan to the southern area and mountain area as the core, two areas of Nam-Gu and six areas of Jung-Gu such as Duryu Park and, Dalsung Park as footholds and other school land and park facility areas as footholds-to-be areas. In particular, Camp Walker, which is connected with Apsan, is not only a foothold but connected to the core, is necessary to preserve after being transferred from the U.S. Army. In addition, assigning the Susung Bridge area of Jung-Gu and the Camp Walker area of Nam-Gu as the wind corridor areas is recommended.

This paper was to examine the existing foundation of cultural contents industry through analyzing the development process, the location pattern, and the value chain system and the management of cultural contents industry in Daegu. Most cultural contents industry in Daegu had less than ten employees: so, it was classified into the early stage of commercialization. The firms that dealt with on-line distribution were recently founded. The high portion of the finns was located in the center of city such as Jung-Gu and Nam-Gu in which the Center for Digital Industry Promotion of Daegu (DIP) is located. The value main system consisted of four nodes such as creation node, production node, marketing node and distribution node. The production node was played the most important role. Based on value chain system, the cultural contents industry firms in Daegu could be divided into four types: Type I is a contents production firm with a single value chain in the cultural contents industry. Type II is a contents production firm with two or three value chains. Type III is a contents production firm with comprehensive value chain. Type IV is a non contents production firm with multiple value chains.

The purpose of this study is to evaluate the biotope structure of the city center area of Jung-gu for nature experiences and recreation purposes. Jung-gu is the most extremely and rapidly urbanized area of Daegu. This study was conducted under the assumption that the biotope structure of a city center area would be different from the urban area. The results of this study are as follows: 1) There are 11 biotope type groups as designated as commercial and work-area biotope type group, and 41 detailed biotope types designated as commercial areas with a lack of greenspace biotope type. 2) The commercial and work area biotope type group has the largest area with 34% of the total area, and the square biotope type group has the smallest area with 34% of total area. 3) The result of primary biotope evaluation is that there are 12 biotope types that have greater than third grade, apart from the biotope type of park that includes natural vegetation. The first grade of biotope type has not appeared in this area, however, the fifth grade of biotope type has 20 biotope types with the biotope type of construction work area (JA). 4) The results of the secondary biotope evaluation are 1 biotope for la, 9 biotopes for 2a, 9 biotopes for 2b, 14 biotopes for 2c and no biotope for 2a. This study suggests that a detailed investigation and improvement plan for high-value biotope areas in the city center area must be continued.

Objectives : In Traditional Korean Medicine, Epimedium koreanum Nakai has diverse pharmacological activities to treat impotence, forgetfulness, cataract and exophthalmos. Present study investigated anti-fibrogenic effects of E. koreanum water extract (EKE) in hepatic stellate cells (HSCs). Methods : To study anti-fibrogenic effects of EKE, LX-2 cells, a human immortalized HSCs, were pre-treated with $3-300{\mu}g/mL$ of EKE, and then subsequently exposed to 5 ng/mL of transforming growth $factor-{\beta}1$ ($TGF-{\beta}1$). Expression level of ${\alpha}-smooth$ muscle actin was determined by immunoblot analysis. Phosphorylation of Smad, transactivation of Smad, and expression of plasminogen activator inhibitor-1 (PAI-1) were monitored to investigate the effect of EKE on $TGF-{\beta}1-mediated$ signaling pathway. Results : Up to $100{\mu}g/mL$, EKE did not show any cytotoxicity on LX-2 cells. Pre-treatment of EKE ($100{\mu}g/mL$) significantly inhibited ${\alpha}-smooth$ muscle actin expression induced by $TGF-{\beta}1$. In addition, EKE significantly decreased Smad2 and Smad3 phosphorylations, Smad binding element-driven luciferase activity and PAI-1 expression by $TGF-{\beta}1$. Of three flavonoid compounds found in EKE, only quercertin ($30{\mu}M$) attenuated $TGF-{\beta}1-mediated$ PAI-1 expression. Conclusion : These results suggest that EKE has an ability to suppress fibrogenic process in HSCs via inhibition of $TGF-{\beta}1/Smad$ signaling pathway.
