Educational Facility has a specialty that similar design is repeatedly taken place so the importance of POE(Post Occupancy Evaluation) is increased for the improvement of problem appeared at the former projects. The POE could provides help to the design of next project and the direction when the need of remodeling is faced. Through the process of POE, the repeat of design mistakes could be prevented and the good information related with building efficiency and other problems could be applied to the design of next school project . In this study, the POE of Manbalro(barefoot) toilet of D Elementary school in rural area of H county is performed. The toilet is renovated as an educational environment improvement project of H county educational office in Chungcheong Namdo Province. The study is focused on the user's behavior at Manbalro toilet for carrying out indicative POE by the subjective response of user's. From the research, several being reformed items is proposed however the toilet is evaluated as a successful project that design purpose of initial stage is applied well.

In a dynamically changing environment, the manager of a maintenance and remodeling (M/R) program is confronted with an increasing complexity of coordinating and cooperating multi-resource constrained multiple projects. The root causes of the complexity, uncertainty and interdependence, cause an internal disruption of an activity and chain reactions of disturbance propagation that deteriorate the stability and manageability of the program. This paper evaluates previous endeavors to apply production control and management techniques to the construction industry, and investigates the possibility of applying other management concepts and theories to organizational program management. In particular, this paper proposes a buffer allocation model by which periodic buffers are allocated in the flows of program constraint resources to stabilize a program master schedule instead of protecting individual activities. Comparative experiments by Monte Carlo simulations illustrate improved performance of the proposed model in terms of program's goals: productivity, flexibility, and long-term stability.

Given the importance of ensuring continued residency and maintenance of the 1st Planned New Town, which is the first of more than 20 such projects, this study aims to identify the factors determining the residents' living intention. The results show that age, gender, length of stay, and occupancy type are significant factors influencing their living intention. Among the environmental factors, the educational environment and shopping environment are crucial. This means that in order to achieve the "Ageing in Place" concept, it is necessary to improve the educational environment, provide a variety of commercial facilities and expand the living facilities. While it has no direct influence on the pros and cons of building remodeling, the results showed that when the living intention is used as a parameter, the transportation, educational, and shopping environment have an indirect influence on the pros and cons of building remodeling.

The purpose of this paper was to comparatively investigate the efficient building incentives in Korea and foreign countries and to seek strategies to enhance low energy building integrated design market infrastructure in Korea. The structure of incentive policies were composed of four main component: 1) types of financial aids and beneficiaries, 2) energy performance criteria and verification methods, 3) supports for low energy building integrated design, and 4) funding sources for incentive programs. Every overseas incentive program has adopted a design team incentive along with building owners incentive and the range of target buildings have been extended from new construction to remodeling projects. The main system of the program is the performance standard through which projects were investigated and the level of incentive are decided. Initially, the integrated performance has been investigated through simulation methods, but the construction performance evaluation and energy monitoring methods are emerging. In addition, the direct support and educational support for integrated design has been provided to enhance the foundation of relative markets. Financial funding is also a key component of the program and more aggressive funding strategies have been adopted.

Vacant houses are increasing across the country, but the appropriate measures have not been set up yet. Accordingly, vacant houses are left unattended for a long time, and become deserted to degrade the residential environment. They are often used as the space for the deviation of youth or even for crimes, threatening the safety of rural society. Vacant houses are not only personal properties but also public assets that form the residential environment of a town. Therefore, the problem should be better taken care of with appropriate policies. In this study, the present situation of vacant houses in Korea, the causes of the vacant house and the limits and lessons of the improvement projects were reviewed, along with the vacant house improvement systems in the UK and Japan. The most significant difference between the cases in Korea and other countries are the method of vacant house improvement. In terms of policies and support, Korea focuses on demolition, whereas other countries focus on reuse. In addition, the vacant house improvement projects in Korea are performed mostly by government agencies, whereas local governments and private organizations in other countries cooperate to improve vacant houses and go beyond mere residential environment improvement towards the local revitalization. Based on the study results, the following are proposed to efficiently improve and use the rural vacant houses. First, the Rearrangement of Agricultural and Fishing Villages Act, which allows the vacant houses to be left unattended and not improved, should be revised. Second, the intermediate support organizations that connect the demand and supply should be fostered and supported so that the use of vacant houses can be vitalized and privately led. Third, the best practices of using the vacant houses should be found and promoted, and the vacant house remodeling technique should be developed and propagated. Fourth, a special law should be enacted to comprehensively plan, support and execute the vacant house improvement, as in Japan. Finally, the value of the vacant houses as public properties should be shared in public so that all citizens can participate in addressing the vacant house issue to derive the detailed plans to solve the problem.

Jacked pile that involves the use of hydraulic jacks to press the piles into the ground is free from noise and vibration, and is possibly installed within a limited construction area. Thus, as an alternative to conventional pile driving methods, pile jacking could become widely accepted for the construction projects in urban area (e.g., reconstruction or remodeling construction projects). Great concern has arisen over the prediction of axially loaded jacked pile behavior. Against this background, a series of pile load tests were hence conducted on a jacked steel pipe pile installed in weathered zone (i.e., weathered soil and weathered rock). From the test results, base resistance and shaft resistance for each test condition were evaluated and compared with the values predicted by the previous driven pile resistance assessment method. Test results showed that the previous driven pile resistance assessment method highly underestimated both the base and shaft resistances of a jacked pile; differences were more obviously observed with the shaft resistance. The reason for this discrepancy is that a driven pile normally experiences a larger number of loading/unloading cycles during installation, and therefore shows significantly degraded stiffness of surrounding soil. Based on the results of the pile load tests, particular attention was given to the modification of the previous driven pile resistance assessment method for investigating the axially loaded jacked pile behavior.

Recently, the remodeling projects of old low-rise buildings were launched in Korea. However, most of them were not satisfied with the value set forth by the KBC2005. Even though there are some research studies on how to improve the seismic performance of such buildings as newly constructed buildings, there is little research in measuring the actual vibrations on low old buildings to prove the effect of retrofit. There also has not been any in-depth research on the dynamic characteristics of full-scale structures using vibration measurements of the building that was damaged to failure. Using an actuator, the dynamic characteristics of reinforced three-storey concrete buildings were evaluated before and after they were damaged. After an 80-mm horizontal displacement by the actuator, frequency in the long and short directions were reduced to 20.85% and 5.77% respectively ; damping ratio was also reduced to 53.9% and 23.15% respectively.

It has been almost 20 years since Korea has started the research of school facilities, but there has not been any form of organized information or studies done about such a trend of the research. In this respect, this research places its focus on categorizing 44 policy studies initiated and proceeded by different organizations for last twenty years(1983-2004) and 186 volumes of the research about education facility plans and projects released by journal of Architectural Institute of Korea and journal of Korean Institute of Educational Facilities in 17 subjects of this study. It also concentrates on organizing data based on different levels of schools and periods of time as well as understanding the trend. The result of this research is followings. Considering every volume of the paper and the subjects that have previously been treated in those papers, the trend of this study is divided into the first stage of research period(1983-1993), the second stage of research period(1994-2001), and the third stage of research period(2002-present). Of all the papers, there has been the most number of papers objecting elementary schools(110 volumes, 56.1%), and most of them focused on space formation, size, and the present situation of utilization of each classroom in elementary schools. In the meantime, the studies about educational information, application of the media, space formation and size under teachers'consent, two-dimension types, a design of outdoor space(including gardens), the present situation of utilization, remodeling of school facilities, an evaluation of space and recognition-awareness analysis have been mainly done since 1995. Such a result mentioned above provides a sense of understanding about a level of studies about education facilities in our country, and as a basic source for future guidelines of studies and contents, in my personal opinion, it contains a high level of application.

Due to the Climate change and resource shortage by global warming, various problems are rising and getting worse around the world. Many countries are doing the considerable efforts to reduce greenhouse gas emissions. The government of South Korea also plans to decrease greenhouse gas emission, the various pilot projects are underway, which includes obligation of energy efficiency 1st rating and greenhouse gas target management system of public buildings. In particular, luxurious government office buildings and energy-wasting public building have issued and emerged as a social problem. Energy efficiency improvement of the existing public office buildings are becoming an important issue recently. This study is proposed the step-by-step energy improvement model according to the building energy efficiency rate in order to reduce the energy consumption. To attain this end, I set up a base model by analyzing the current architectural conditions of the existing public office buildings and grasped the specific properties of building energy consumption through energy simulations. Furthermore, I suggested phased reduction prototypes for the reduction target of energy consumption by applying the methods of the zero energy building plan. This study is expecting that prototypes would give directions when it comes to planning the implementation policy of phased building plan factors, according the building energy consumption reduction goal in the existing public office buildings which are the subject of building energy target management system.

The purpose of this study was to determine the incomplete aspects of the government pilot project 'Livable City Making' Also, the study was conducted to consider a plan that residents will satisfy for the realization of the project. The study used a case study and a survey method in research process. For the case study, two projects in Busan that have similar planning were chosen. The contents of the survey included the residents' interest in their housing area, their recognition and opinions of the pilot project, their satisfaction about the environmental alterations, and their thought about conditions of sustainable housing. The main results of this study were as follows. First, the residents were satisfied with the alteration of the street space and the provision of green and open spaces. Meanwhile they revealed that the preservation of the natural environment and the vitalization of community are insufficient. Second, they also believed that the construction of the pedestrian streets, the provision of parking lots, and the remodeling of the deteriorated buildings are incomplete. Third, the residents believed that the following provisions need to be made for successful sustainable housing waste discharge needs to be minimized, facilities need to be used for saving energy, opportunities for employment need to be provided within their housing areas, and safe street spaces and comfortable traffic systems need to be provided.
