The study shows solutions of long-term unexecuted urban park and activation plans to facilitate the business promotion of Private Park Developers. This study conducted a feasibility analysis to determine if the business of a special case is applicable. The result of this study is as follows about three long-term unexecuted urban parks in Gwangju Metropolitan City's City Park. First, the three long-term unexecuted urban parks in Gwangju Metropolitan City's City Park are the forest type Neighborhood Parks. Businesses of a special case's park developing cost(average 0.4%) have a relatively low percentage. It is most affected by Land Compensation(average 33.8%) and building construction expenses(average 59.1%). Second, long-term unexecuted urban parks' Land Compensation and building construction expenses seed capital are excessive. The Bongsan Park balance floor space index is 179 percent; a reasonable profit floor space index is 220 percent. The Mareuk Park balance floor space index is 351 percent; a reasonable profit floor space index is 420 percent. The Jungoe Park balance floor space index is 327 percent; a reasonable profit floor space index is 400 percent. Third, to facilitate the business of special cases in deliberating, Bongsan Park should change its second class general residential area. Jungoe Park must change the quasi-residential area and semi-residential area. Mareuk Park must change the general commercial area. In this way, the feasibility of promoting private park projects will be improved.

Recently, Korean government documented the plan to cope with the situation related to rich pensioners of Basic old-age pension. The purpose of this paper is to verify that how many rich pensioners are existing and to evaluate government reform plan's validity and effect. Main results are as follows; firstly, if the definition of rich pensioners is on the top 10%, the proportion of them would form 2.9% of total. And then, an amount of expenditure for them is only 2.6% of total. Secondly, in terms of disposable income, debt, and transfer income from child, the household who would be applied by government's plan is not richer than other household who is in the same living standard. And then, if the government's plan enforced, the effect might be very small. Lastly, the plan of government will discriminate against persons who support their parent. As a result, Basic old-age pension will be worsen. This paper should underline that the government's reform is only the 'hidden' retrenchment strategy in order to introduce a standard of the obligation to support own parent in the state without scientific prediction and serious discussion of negative public opinion. That is why, this is the same as the 'Trojan Horse'.

The purpose of this paper is to analyze the relationship between the budget allocation of Busan-Gwangyang port and political variables such as general election, presidential election, local election and political regimes. To do this, this study did correlation analyses using budget data of all ports in Korea, Busan, and Gwangyang during 1985-2007. The main results of the correlation analyses are as follow: First, there was a positive correlation between budget of Busan and local election. Also, there was a positive correlation between budget of Gwangyang and presidential election. This results suggest that public choice model and political business cycle model seem to apply to the port development policy. Second, there was no correlation between the regionalism of the political regime and budget of Busan-Gwangyang ports. Third, it can be inferred that the national agenda of the hub strategy can be positively related to the implementation of port development budget. Further studies are needed to analyse the relationship between the political variables and establishment of port plan, decision making about port development and ground-breaking of port construction.

The construction of a facility is an act whereby infrastructure such as roads and railways and other facilities such as housing and office spaces are constructed, and due to the characteristics of the relevant industry where such construction is carried out in a custom order method, it requires a long period of time mostly. While the construction is carried out over a long period of time, fluctuations in the price of raw materials required for the construction occur. Therefore, the cost of the construction also fluctuates inevitably. The fluctuation of the construction cost meshes closely with the profit of a constructor and the efficiency of government spending. Therefore, it is necessary to maintain the construction cost at a reasonable level by adjusting the construction cost rationally in order to secure the required construction quality and spend the budget efficiently. The buffer system for solving such problem is the contract amount adjustment system by fluctuations in prices (Escalation/De-Escalation). In this study, the method combining the escalation method based on the item adjustment method was suggested for an efficient contract amount adjustment method. In addition, it is proposed that there be an investigation and codification of matters not applied to government acts and regulations on contracts related to the adjustment of fluctuations in prices legally.

This study analyzed appropriate equipment combination for emergency recovery after flood disasters and proposed an alternative approach for economic and rapid emergency recovery based on the utilization of human resources who have practical experience in construction business and in equipment operation. The current countermeasures and response to flood disaster including emergency procedures and methodologies are investigated and related legal framework was also analyzed. Currently, some emergency recovery works are over payed and delayed due to unclear and inefficient processes on equipment and human resources mobilization during and after flood disasters, particularly in local governments. Best practices in mobilizing equipment and human resources were compiled, theoretical foundation was investigated and analyzed, and improved emergency recovery schemes were proposed for effective flood disaster countermeasures in local government. Prioritization in equipment and human resources mobilization was also proposed considering equipment transportation distance and accessability to disaster sites. This study also proposed improved ways to utilize experts in local areas in supporting community emergency response volunteers for disaster risk management.

The maintenance expenses of public rental housing have drastically been increased as facilities become obsolete. As an effective means of managing such a situation, accurate estimating of maintenance expenses and securing financial resources are crucially important. It, therefore, is necessary to analyze major factors affecting on maintenance expenses of public rental housing's facilities, and develop an effective instrument to estimate them. On the other hand, the U.S.A, where approximately 60 percent of public rental housing's operating costs are supported by the state, has already developed an effective tool to forecast operating costs based on several years' actual data. As a result, public rental housing has been operating with a reasonable level. However, there have been no remarkable researches and studies in this field in Korea. In this context, this study attempts to examine principal determinants of maintenance expenses of public rental housing's facilities, and their influence based on the latest five years' actual operating costs. This study may contribute to develop an objective and precise tool to forecast maintenance expenses of public rental housing.

Due to structural problems in the transportation market, such as fraudulent competition and multi-level transportation transactions, tariff are not properly refIected to the final trucker even if freight tariff are increased due to diesel price hikes and transportation cost increases. By Launched "standard tariff system" in 2017 based on the trucks, government would tried to guarantee the minimum tariff such that prevents overloading, speeding, and strain for trucker. However, It is necessary to analyze in advance the issue of the system and its impact on container freight. Thus, this study analyzes the issues and countermeasures related to the tariff system that is formed when the "Truck Safety Rates" is introduced, and also analyzes the influence factors of the expenditure cost on the container freight which is applied to the "Truck Safety Rates".

Total Project Cost Management System(TPCMS) was introduced with the purpose of increasing the efficiency of cost control for public construction project in 1994. In this paper, general perception of participants of the public construction project on the TPCMS was examined, and the problems in implementing the TPCMS was figured out through expert interviews and survey. Then better ways to implement the system were drawn based on the problems. To effectively manage the cost of public construction project, basically project cost should be estimated accurately in planning stage and managed based on it to have a project complete within the budget. In addition, the cost need to be managed in more systematic ways in terms of data collection and analysis, and the autonomy in managing the project cost given to the project owner needs to be expanded. Most of all, proper budget should be provided to prevent a project from delay through setting the priority of projects and proper budget allocation based on the priority.
