Purpose: Recently, Housing area plan has tried to reflect a public space of various forms. However, most of cases are indiscriminately developments, which don't reflect the diverse needs of residents. In addition, a subject of the public space is not clear and consistently stable of the management, so the residents don't have an interest enough to take advantage of it. Method: In order to make a plan of the public space of a residential complex, an architect designer needs to take a few things into consideration. One is a physical facility in needs. And other one is a management of keeping a social place stably and consistently, which allows residents to be able to interact with each other. It should be regarded for residents to form a sense of belonging, while minimizing the interface friction. When all these problems are fulfilled, an interaction will be made to improve the quality of the living environment. Result: Therefore, in this study, it is necessary to define the meaning of territoriality of the external public space of housing complex. This study makes it possible to improve the relationship of neighborhood and the quality of the life for the residents, depending on the time. This is the first step as 'the research for the territoriality of the external public space of housing complex', in order to define about the concept, function, characteristic of territory(the base of territoriality) and to establish the territoriality that can form the physical or psychological boundary in public space.

Purpose: In this study, we investigated the better application of the law which is about the AED installation and more effective ways of emergency medical care system, to understand the law and to research the current condition of public facilities which belong to local governments, and to seize the aspect of safety guards who currently work in order to provide the installation of AED in the public facilities and to provide more efficient emergency medical service with the effectuation of the immunity law of the good intention of first-aid treatment. Methods: In Gwang-ju, 234 public facilities have been identified by 31 December, 2008. With the exception of the duplication, we researched 158 facilities and received the answers from 95 of them. Results: In the research, 53% of them have had internal emergency first-aid education, and 55% of them didn't have this education and a CPR education manual, and 30% of the facilities even didn't know how to connect with the manager of the company for the first-aid department. On the other hand, most of them were highly interested in CPR and AED education on the ratio of 91% and 93%. 88% of them have been trained about first-aid, 51% of them haven't been retrained, 17% have never been trained. so, the reality of emergency system at public facilities is serious. 78% of them knew they are working at public facilities, though 49% of them didn't know about AED installation. 57% of them didn't know the fact there is the immunity law related with good intentions for first-aid treatment. 63% of the facilities have security guards, and 30% of them didn't answer the questions. Also, many of them agreed to the opinion that all employees should have first-aid training. At representative survey report of participator of public-facility, emergency treatment is 61%, 16% of patients calling. Accordingly they importantly think better doing an on-site first-aid than evacuating the patient. And the rates show that 57% of them answerers tend to call Fire-Office(119) for evacuating the patients, and 28% of them EMIC(1339) for the first-aid. Conclusions: In this study, we are suggest to improve the details of the efficient operations and management after the grasp of the uninstallation, indifference, and unreliable conditions of AED. 1) Need a publicity of AED install cognition which is an emergency medical instrument at public facilities. 2) Arrangement of safety agents at facilities and concerns about them for good management from the parties concerned. 3) Need a designation of legal details according to the decision of the AED installation and the standard of the AED installation. 4) Training about first-aid of safety guards and the persons concerned in the facilities should be practiced participation with the positive and through this, first-aid treatment could be done by anyone who knows the immunity law related to medical emergency. 5) The brochures for the potential users and the results form practicing the instructions need to be improved in many ways through recording the emergency cases that have happened.

Concentration and identification of airborne bacteria in the regulated public facilities were examined with the six-stage cascade impactor. Geometric mean total and respirable concentrations of airborne bacteria were $404cfu/m^3$ and $194cfu/m^3$ in hospital, $931cfu/m^3$ and $358cfu/m^3$ in kindergarten, $294cfu/m^3$ and $134cfu/m^3$ in day-care center, and $586cfu/m^3$ and $254cfu/m^3$ in postpartum nurse center, respectively. As a result, culturable total and respirable concentrations of airborne bacteria were significantly highest in kindergarten and lowest in day-care center (p<0.05). The ratio of respirable to total concentration of airborne bacteria in the investigated public facilities was ranged from 30% to 40% but there was no significant difference among them (p>0.05). The mean I/O ratio of culturable total and respirable concentrations were 0.58 and 0.66 in hospital, 0.71 and 0.83 in kindergarten, 0.28 and 0.41 in day-care center, and 0.63 and 0.78 in postpartum nurse center, respectively. Day-care center showed the lowest I/O ratio of culturable total and respirable concentration of airborne bacteria (p<0.05) but a significant difference was not found among other facilities. Indoor concentration of airborne bacteria did not correlated significantly with indoor temperature and relative humidity (p>0.05) but had a significant positive correlation with $CO_2$ and surrounding condition (p<0.05). Staphylococcus spp., Micrococcus spp., Corynebacterium spp., and Bacillus spp. were dominant genera and amounted to over 95% of total airborne bacteria identified in the investigated public facilities. Size distributions of four dominant genera did not observed inconsistently regardless of type of public facility.

본 연구는 공공하수처리시설의 다양한 운영방식(직영, 공공 위탁, 민간 대행)에 따른 성과의 차이를 분석하고 연구 결과를 토대로 국민에게 가장 효율적이고 높은 수준의 하수처리 서비스를 제공할 수 있는 운영방식과 개선방안을 도출하고자 하는 목적을 가진 연구이다. 이를 위해 경제적 성과지표(하수처리 비용, 하수도 요금)와 사회적 성과지표(수질, 민원 수)를 선정하여 횡단 분석(cross-section data)과 종단 분석(longitudinal analysis)의 방법으로 세 집단 이상의 평균 차이 검증을 일원분산분석(ANOVA)을 통해 실시하였다. 분석 결과 횡단 분석에서의 경제적 성과 차원에서는 운영방식에 따라 차이가 나타나지 않았으나, 사회적 성과 차원에서는 운영방식별로 차이가 나타나는 것을 알 수 있었다. 수질 지표의 경우 공공 위탁에서, 민원 발생 건수에서는 민간 대행에서 직영 대비 우수한 성과를 보이고 있었다. 종단 분석에서는 대부분 성과지표에서 운영방식별로 유의미한 차이가 나타나지 않았다. 따라서 공공서비스의 효율성 제고와 서비스 수준 제고를 위해서는 공공 위탁이나 민간 대행 도입 논리 외에 서비스별 특성에 맞는 다양한 접근이 요구된다고 하겠다. 아울러 향후 지자체가 하수도 위탁을 추진한다면 서비스의 성격과 지자체별 특수성, 서비스 이용자의 니즈 등을 잘 파악하여 추진하는 것이 필요하다.
