The long-term repair program is significant as the execution standard for apartment in repair construction, and provides the basis for effective facility management through appropriation reserve and preventive maintenance. Considering its importance, the government legislates the items, cycle, and ratio for long-term repair. However, the frequent changes, controversies on repair, and difficulties in using appropriation reserve are caused as the items have not been revised on time reflecting up-to-date construction technologies. In order to resolve these problems, it is required to improve the standard by evaluating the appropriateness of repair items throughout the analysis of actual conditions. This study aims to suggest the revision plan for the criteria with the major items based on the status identified by the actual long-term repair programs and historical repair construction data. To do this, the adoption ratios of items to program are reviewed by collecting the real cases of the long-term repair programs. Developing improvement plan was approached in two ways such as "exclusion method" deleting minimum unnecessary items and "selection method" sorting out items with high adoption ratio and evidence of repair in a positive manner. Aa a result, the major items were identified as 118 items and 73 items by exclusion method and selection method respectively from the current 147 items. The outcomes of this study are expected to contribute enhancing the practicality of the standard in that the regulation for long-term repair program should periodically reflect the status of currently applied construction methods and materials.

The Busan New Port and its hinterland have not operated smoothly due to the complicated laws and various related organizations. Thus, many projects involving the port are not matched with its purpose of establishment. In particular, a large-scale apartment complex, which was constructed without a negotiation among the related organizations, is disturbing the port's logistics function. Also, the construction and management of every traffic facilities are conducted by various organizations due to the functions for the facilities are dispersed among them, which has given rise to chaos and responsibility-shifting. As a result, worries about the friction among the organizations and the loss of function of the port hinterland exist. This paper analyzes the problems of inter-governmental functional distributions in the construction and management of the port hinterland of the Busan New Port based on the principles (theories) of functional distribution. In addition, this paper proposes improvements for the functional distribution. The results of the analysis indicated that the functions for housing and traffic facilities were duplicated and dispersed among organizations, resulting in an unclear division of responsibilities. Finally, the paper proposed solutions for the problems: the institutionalization of an administrative conference system among related organizations, using an integrated administration for a wide area (contracting-out, association among local governments), and establishing a special-purpose local government (association among local governments, BPA).

At present, many problems in traffic operation and safety occurs since there is no clear design criteria on designating the not-permitted entrance/exit section at curb areas within complex areas. Even, there is no specific and detailed researches on the not-permitted entrance/exit section by now. This research calculated the proper length of the entrance/exit section at curb areas by dividing the access not-permitted section into the two sections. First, the calculation of the entrance section was done by considering the location of crosswalks, stop line clearance, the queue length of vehicles approaching to second lanes, and marginal distance for safety have been considered. Second, the calculation of the exit section was done by comparing and analyzing the distance between cars of the entrance section according to the investigation point and the distance considering the location of crosswalks, the behavior of exit vehicles and the length of vehicles. In conclusion, by presenting the proper length in consideration of the traffic operation and safety on the access not-permitted section within complex areas, it can be used as a traffic safety improvement alternative and will be contributed in establishing and operating the proper installation criteria for the access not-permitted section within complex areas.

It is expected that the number of apartment complexes in Korea that are over 20 years old will rapidly increase to more than 3,500,000. Consequently, the remodeling of these buildings is being revitalized throughout the country. Among the requirements for such remodeling, the expansion of parking lots has considerable weight. When enlarging a parking lot, the access route from an underground floor to the main building (i.e., the means of entry into the main building) determines the possibility of vertical enlargement for elevators, the size of the parking lot, the construction period, and construction expenses, etc. When enlarging an underground parking lot of an apartment complex, the access between the main building and the parking lot, as well as the inhabitants' requirements for entering the main building, are generally determined based on the designer's experience, rather than on the exact estimation of the peculiarity of the complex. In order to resolve such a problem, when enlarging an underground parking lot, a systematic and rational method is needed for selecting the means of entry into the main building. In this study, a selection model is derived for the method of selecting an access route into the main building when constructing an underground parking lot, in order to provide a reasonable decision-making process. A research method was investigated for determining the access route into the main building when enlarging a parking lot. On the basis of research carried out through in-depth interviews with experts, the characteristics for each means of entry into the main building were analyzed and the factors affecting the selection of the access route were deduced. The affecting factors selected were construction efficiency, convenience efficiency and economic efficiency. Weight values were then estimated for the selected affecting factors by applying the AHP method. Results showed that convenience efficiency, which gained the highest value, is the most important factor in selecting the means of entry into the main building. The most suitable means of entry into the main building was also suggested after estimating the applicability of the site by selecting complexes with remodeling possibility. This study will be applied as a reference for selecting the means of entry into the main building when constructing an underground parking lot particularly for older apartment complexes.

This study has been conducted focusing on the analysis of the turn-key proposal for Gimpo-Han River New City. The study expected that it would come up with design trends and introduction properties of each plan for the eco-friendly development of an apartment house. The concept of environment-friendly design was thought in four parts: 'Land use and transportation,' 'Ecological environment', 'Energy resource and environmental impact' and analysis factors of each part were chosen by specific items from the prospective researches and guidelines that already given on the projects. In conclusion, a proper development of the environmental-friendly apartment house will not be achieved unless the designers try to overcome their prejudice against eco-friendly planning elements applications. Along with the designers' attempt, it is also necessary to review the evaluation articles of the certification system for the existing environmental-friendly structures as well as to compensate and establish detailed evaluation standards. As the problems are being worked on, an integrated, effective evaluation standard for the eco-friendly planning elements will be determined. This way, an environmental-friendly residential development with a better quality will be eventually realized.

This paper quantitatively analyzes the investment performance of the environmental improvement fund focusing on the sales effect and the housing benefit effect. The analysis of this study focused on the effects of sales and housing benefits for completed business sites among the business sites supported by the Environmental Improvement Fund. The analysis results are as follows. First, it appears that the sales effect of the completed workplace is effective compared to the amount of investment, so it seems that the purpose of industrial integration of the environment improvement fund is being achieved. Second, it was found that there are variations by workplace and region in housing benefits. This seems to be due to the fact that profitability can be neglected by reflecting the characteristics of residential facilities built by private businesses. The Environmental Improvement Fund is a policy fund that pursues both profitability and publicity. Therefore, it is necessary to transform the structure of the fund to expand support for industrial infrastructure with high publicity. To this end, it is necessary to establish a long-term management plan that equitably considers the profitability and publicity of the environmental improvement fund.
