Recently, the central and local government support various improvement projects on existing public buildings and areas. Improving public use and environment of these areas is adequate because financial condition of local city is not enough to build new infrastructures. As one of the projects, Geochang-Eup(Geochang-Gun, Gyeongnam Province) is selected as the project site since most of the public buildings and areas of the city are located close each other in downtown but not streamlined in function and use nor easily accessible. The purpose of this study is to analyze the causes of decline in local city and to present strategies to vitalize the city through improving environment of public areas. And we analyzed the problems by discussion with local officer, field investigation on the site and paper survey. The analysis shows that public infrastructures are grouped by function: administration, education, life support, culture, health, etc, but not well-connected, easily accessible, adequately located, various in use nor enough in quantity. This study summarized the problems into five categories: Access&Linkage, Safe&Comfort, Identity&Image, Usage&Activity and Ownership&Management and proposes strategy in three phases. The first phase is to improve functions and design of public places per each area: more consistent design on public buildings, better civil facilities and better accessibility to public areas. The second is to vitalize of the areas and to improve efficiency in use through linking each other physically and sharing uses. The third is to encourage citizen's participation and by developing civil programs to streamline public areas each other.

Instrumental neutron activation analysis was used to measure the concentrations of 27 elements associated with respirable particulate matter (PM10) that were collected from the Third and Fourth Industrial Complex Area of Daejeon City. The distribution patterns of elements were clearly distinguished with their concentrations varying across more than four orders of magnitude. The mean for Al were recorded to be the highest value of 1,527 $ng/m^3$, while that for In showed the lowest value of 0.1 $ng/m^3$. If compared in terms of enrichment factors, it was found that certain elements (e.g., As, Br, Cl, Cr, I, In, Sb, Se, and Zn) are enriched in PM10 samples of the study site. The results of factor analysis indicated six factors with statistical significance, which may exert dominant controls on regulating the elemental concentration levels in the study area.

The purpose of this study is to suggest an activation plan for community centers. The community centers, categorized into 3 types by the number of visitors, were comparatively analyzed by their programs, operation, and visitors' opinion. 6 community centers in Heungduk-gu, Cheongju-city, their 6 operators, and their 220 visitors were the sample. This study surveyed community centers on the spot about their space characteristics and programs, interviewed operators, and asked questionnaires to visitors. The data of the 3 categorized centers were analyzed by frequency, average, and percentage. The following is the result: 1) The number of visitors was dependent on the type of residence and age of the residents. The activated community centers were found in residence type apartment blocks, and with an age group in its 40s. 2) The space satisfaction was dependent on the year of construction; it was higher with newer buildings and wider sizes. 3) All the centers were affirmative on the communication of the participants of programs. In conclusion, the activation plan of the community center has to comprise a renovation of old buildings, public promotion, and the development of programs taking into consideration the age group of the residents.

The rapid industrialization since the 1960s has caused considerable changes in the appearance of Korean cities. The huge demand and cityward tendency derived from the increase of population with such the expansion from 9 millions in 1960 to 43 millions in 2003, have resulted in number of problems such as the falling-off in the quality of life, amenity, and safety. And above all, the urban identities is not to be found obviously in the cities. With regard to these problems, the re-creation of cities should be emphasized to make environmental, economical, and social improvements and to restore human-oriented activities. In the course of making new improvements cities need to preserve the characteristics and maintain the concordance with their environments. In other words, the restoration of cities ought to be made in the aspect of continuity, which means the accession of genetic factors inherent in cities. In this background, concerning about the system on apartment house especially relating to environmentally sound restoration and comparing with that of Japan, this study proposes the direction needed in the development of urban space.

Public transportation systems play key roles in supporting dynamic activities and interaction between urban places. Especially, high efficient public transportation systems are required in order to support large traffic demands in urban areas. In this paper, we define a new metric, structural activation level (SAL), to replace the conventional transportation share ratio (TSR) measuring efficiency of public transportation systems. First of all, we access the Korea Transport Database (KTDB) and download origin-destination data by transport types to construct traffic networks with respect to transport types for each city. Then, we calculate the QAP (Quadratic Assignment Procedure) correlation between each traffic network and the total traffic network for each city to investigate SAL by comparing cities one another. The results of our investigation reveal inconsistency between TSR and SAL. In Daegu, TSR of public transportation systems is relatively low while SAL is high. In Deajeon, however, SAL is low while TSR is high. Therefore, we suggest to take into consideration SAL as well as TSR in order to investigate the degree of activation of public transportation.

본 연구는 무연탄올 원료로 제조한 활성탄의 활성화 시간과 burn-off에 따른 세공구조의 변화를 고찰한 것으로 77K에서 질소 흡착실험에 의해 특성을 분석했다. 활성화 시간의 증가에 따라 burn-off는 거의 선형적으로 증가하며, burn-off를 증가시킴에 따라 제조된 활성탄의 총세공부피와 BET 비표면적은 증가했다. $800^{\circ}C$의 활성화는 $950^{\circ}C$의 활성화에 비해 미세세공(micropore)을 많이 생성시켰고, 동일한 burn-off에서는 저온에서 활성화시킨 활성탄에 미세세공이 발달하고 고온에서 활성화시킨 활성탄에 중간이상의 세공이 더 발달해 있었다. 수증기 활성화에 의해서는 직경 $100{\AA}$ 이하의 세공이 주로 발달되었으며 특히 $6{\sim}40{\AA}$ 범위의 세공은 burn-off의 정도에 따라 상당히 발달됨을 알 수 있었다.

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.
