Difference found in the degree of activating commercial space in subway stations is getting bigger and bigger. With an assumption that commercial space in stations demands public management, this study is aimed to figure out factors that influence the activation of commercial space in stations. To address the goal, the AHP was adopted to draw the importance of activation indexes. Applying the importance of activation indexes drawn, this study analyzed 260 stations located in Seoul regarding the ranking of activation of the stations and also the characteristics of each individual region and index. According to the findings of analysis, there exists a great gap in the degree of activation by either life zones or autonomous districts, and factors having big influence over activation are found to be floating population and the number of passengers getting in or out.

The vitality of the city's commercial district, which in the base of city life and provides vitality and diversity of life, has a great impact on the vitality of the entire city and the revitalization of the local economy. The revitalization of the commercial street is related to the activation of walking, and walking is closely related to the quality of life because it involves a wide range of interactions with the surrounding environment beyond simple movement. This quality of life leads to 'Livability'. In order to revitalize pedestrians on the commercial street, the liberty factor was derived and the importance of what was the most important and effective for the activation of the commercial street was analyzed. As a result, it was found that the items representing the atmosphere and purpose, which are detailed indicators of placeness, had a high priority, and it was found that the detailed indicators belonging to accessibility came out with a lower priority. In order to increase the livability of the commercial street, the priority is to increase the spatiality of the space, and if pedestrians are activated as the number of visits and stay time of visitors increases, it can be extended to the vitality of the entire area.

The purpose of this study is examine the characteristics of public open space in the office buildings located in urban commercial strip, in terms of its relationships to street, to building, and to order surrounding facilities. Theoretical basis of this research is that public outdoor spaces are to be the intermediate territory set between streets and a buildings. 5 commercial buildings in Seoul are selected as sample cases and they were closely analyzed in a comparative manner. Based on this comparison, several planning guidelines are suggested for the activation of the space, mainly in terms of the location of public open space in relation to street, the design techniques and devises reflecting the purpose of the space, and territorial arrangement and furniture layout, and the patterns of relationship to surrounding space and facilities.

Based on the results from the already published 'A study on factors that make busy of street space' and 'A study on street the image evaluation of streetscape', this study is an attempt to explore factors, other than the structural factors, that compose the street space and affect the image of street to be more lively. First of all, this study was mainly concentrated on the structure of street space that fits the theory of the previous two theses, stating that the structural ratio ($D/H=0.5{\sim}2$) gives the street an interesting image. The next study subject was the street space that exhibits the amenity and busy of image according to the space structure ratio. I defined that exhibiting amenity and busy means the activation of the street space, and I attempted to extract the activation factors from the component elements. The street space that shows amenity and busy image after the activation was named as 'lively street space' in this study. Furthermore, I selected 20 street spaces, after classifying the whole, according to nations and local characteristics as the previous theses had done and looked for the 'lively street space', whose structural ratio was not in the range of $D/H=0.5{\sim}2$ and the factors that contributed to the Image. As the result, I founded that in case of the business areas with the ratio of $D/H=0.5{\sim}2$, street activation factors were hydroponic facilities, sidewalks, and wayside buildings and In case of the commercial areas, the factors were sidewalk, wayside buildings, hydroponic facilities, and illumination facilities. Especially, 5 commercial areas in Korea and 1 business areas in Japan did not have the structural ratio of $D/H=0.5{\sim}2$, but still exhibited lively image as streets. This was because aside from the structural element, other street activation factors such as facilities also had major contribution in these streets. In other words, in commercial areas in Korea have wayside buildings, sidewalks, and hydroponic facilities as activating factors, whereas in street spaces in business areas in Japan, hydroponic facilities, wayside buildings, and sidewalk factors are influential to the activation of street spaces.

As our lifestyles have changed due to rapid industrialization and urbanization, new social and communication problems have been caused and there have been lots of discussion on regional communication. For communities to become alternatives with realistic meanings in this changed society, considerations on social and spatial conditions are needed. Therefore, public space which works as a device of physical environment for activation of communities needs more active changes which encourages social communication. In respect to the activation of communities, the following suggestions are given: First, physical devices of a urban plaza should be arranged to support various programs presented along with consideration of human behaviors as users. Second, fundamental facilities of the plaza should accommodate various activities through connections with programs and commercial space. Third, when cultural and historical characteristics of the community are understood, the plaza can form regionality and symbolism through artistic representation. And users can form the identity of community. Fourth, transportation facilities should be separated from or coexist with areas of passengers and the plaza should have its own identity through symbolic sculptures.

In this article I discuss the main results of our research in space biology from the simple early investigations with human Iymphocytes in the early eighties until the projects in tissue engineering of the next decade on the international space station ISS. The discovery that T Iymphocyte activation is nearly totally depressed in vitro in 0g conditions showed that mammalian single cells are sensitive to the gravitational environment. Such finding had important implications in basic research, medicine and biotechnology. Low gravity can be used as a tool to investigate complicated and still obscure biological process from a new perspective not available to earth-bound laboratories. Low gravity may also favor certain bioprocesses involving the growth of tissues and thus lead to commercial and medical applications. However, shortage of crew time and of other resources, lack of sophisticated instrumentation, safety constraints pose serious limits to biological endeavors in space laboratories.

Jung-gu in Daegu is an old downtown that has led the development of Daegu as a representative center and a commercial area with historicity and placeless. However, an urban center is losing its vitality due to the transfer of city halls and the development of new towns. The downtown area that is still important in a city should lead urban development continuously so that it needs to return its vitality by rehabilitating the weakling urban center. Accordingly this study makes the school which shows drop in the number of students and classes in the school buildings located in Jung-gu, Daegu. Consequently this study figures out a cause for the occurrence of unused school facilities and find a solution as the space for local residents by investigating the facilities of schools, the surroundings, the reality, and the present condition. This study is conducted to examine actual situations of a downtown area that has gone through development and history of Daegu as a center. To this end, it aims to seek for methods to activate the city by relating the practical use of unused school facilities.

The The purpose of this study is to have a positive impact on the evaluation of the traditional market revitalization project by discussing the business details and implementation process of the commercial district revitalization project in depth. The research method uses practical methods for traditional market revitalization projects. First, the activation method of the place was examined through the concepts of Oldenburg's 'Third Place' and Carr et al.'s 'Five Demands for Public Space' and the theories related to non-face-to-face transactions were examined. The first study case was the commercial district revitalization project of the Cheongju Global Market Development Project(Seongan-gil Street Shopping Mall and Yukgeori traditional Market), which discussed revitalization of open space, revitalization through reproduction, and revitalization through festivals. The revitalization project through representation is a project to install a symbolic sculpture at the estimated location of the 'Namseokgyo' buried in Yukgeori traditional Market. The revitalization through the festival is the Korea Sale Festa, which is a vibrant business due to increased sales at traditional markets and shopping malls and floating population in open spaces. The second study case was the Cultural Tourism Promotion Project(Hanmin traditional Market), which discussed revitalization through the development of local brands and SNS content. In the conclusion, the relationship between the six projects and commercial district revitalization methods was discussed, and policy recommendations were made, mentioning the importance of reflecting regional characteristics in design planning. We hope that this study will be used to positively evaluate the traditional market revitalization project, showing that stakeholders are working hard to produce positive results within institutional limitations.

Lithium sulfur (Li-S) batteries have attracted considerable attention as a promising candidate for next-generation power sources due to their high theoretical energy density, low cost, and eco-friendliness. However, the poor electrical conductivity of sulfur and its insoluble discharging products (Li₂S₂/Li₂S), large volume changes, severe self-discharge, and dissolution of lithium polysulfide intermediates result in rapid capacity fading, low Coulombic efficiency, and safety risks, hindering Li-S battery commercial development. In this study, a three-dimensionally (3D) connected hierarchical porous carbon framework (HPCF) derived from waste sunflower seed shells was synthesized as a sulfur host for Li-S batteries via a chemical activation method. The natural 3D connected structure of the HPCF, originating from the raw material, can effectively enhance the conductivity and accessibility of the electrolyte, accelerating the Li⁺/electron transfer. Additionally, the generated micropores of the HPCF, originated from the chemical activation process, can prevent polysulfide dissolution due to the limited space, thereby improving the electrochemical performance and cycling stability. The HPCF/S cell shows a superior capacity retention of 540 mA h g^-1 after 70 cycles at 0.1 C, and an excellent cycling stability at 2 C for 700 cycles. This study provides a potential biomass-derived material for low-cost long-life Li-S batteries.

This study starts from the architectural and urban interest to integrate the daily life and behavior of residents in the city of Seongnam and to sustain the community. A fixed abode is something that can not be separated from the place and should be approached from a comprehensive perspective reflecting the physical and social conditions of the region. Although residential neighborhoods have a residential walking range, which has a steep slope, it has been formed in the suburbs of the residential area where commercial facilities are activated organically. The humanities and social organizations of the residents are integrated with the physical space and act as constituent factors of major cities. This is an attempt to suggest improvement and activation of existing cities based on their daily lives, rather than destroying cities and creating new ones. Also, it is proposed to 'Neighborhood Street' as an indicator of a uniform urban renewal plan for existing urban regeneration projects. Based on the definition of the city of living in the city, the center of the city will be located in the center of the city, and it will be the center of the city's bustling streets.
