Korea's RPS, which requires that power generation companies obtain a minimum percentage of their generation by using renewable energy, will take effect in 2012. Based on the first-year law enforcement, generation companies have to satisfy 2% of RPS compliance ratio in 2012. Then, the required RPS compliance ratio will increase up to 10% in 2022. Thus generation companies need to construct power plants that utilize various types of renewable energy sources such as PV and wind power. This work is aimed to analyze the cost of such a renewable power source in terms of capital cost, capacity factor, and fuel cost. We provide the analytical expectation on the renewable power generation cost of 2012 focusing on PV, onshore/offshore wind, fuel cell, and IGCC, which are focused by government policy.

Recently, the regulations from the government and the concerns of people be raised to the interest in exhaust and intake noise of passenger car as much as other vehicles. In these demands, performance prediction software was developed in this paper. In this study, Robust design was used for improving the noise reduction capacity of intake system with the performance prediction software. On the basis of the existing design, length and radius of each component that was thought to be effective to the performance of intake system was selected. At first, factors are arranged by using Ll8 table of orthogonal array and then optimum value can be obtained by modified Ll6 table of orthogonal array.

It is to show the problems of the existing techniques to estimate agricultural water demand and to suggest the new methods considering the water demand for non-irrigated area and decrease of water loss in canal. It is to suggest the methods to improve the techniques for estimating agricultural water demand and to analyze the water demand and supply according to the facilities capacity. Until now, the concept of per the unit used to estimate agriculture water demand is useful to estimate demand, but is insufficient to cope with the variations of conditions in future. And the paddy area of government is not realistic against a trend of decrease. Water demand decrease is caused by constructions of irrigation facilities as constructing of irrigation canal, but application loss ratio is fixed. Increase of the water demand owing to the increase of the yield per the unit area is also the actual condition which is not considered. The guide-line must contain these contents for a demand estimate.

The purpose of this study is to illuminate the reason why community building policies by the Government seem to fail to work properly in Korea. The existing studies focus mainly on designing community building systems, thus they cannot provide plausible explanations about the cause of the unsuccessful outcomes from the policies. To overcome the limitations of the existing studies, the authors examine the implementation factors to influence the policy instruments with the perspective of policy implementation. By performing the analysis, the results imply the implementation factors, such as executer's competence, supports by related interests, incentive systems, and legal-institutional instruments, are important to influence the implementation performance of the relevant policy instruments. To make community building successful policies, The authors therefore suggest that the capacity of local administrators and residents should be raise, and one of which the way to enhance is to support research and program development by the resident-oriented living laboratory systems in localities.

To promote the nation's exports, in Korea several government led programs are alive for procuring and manufacturing goods for export. The trade supporting programs are consisted of Trade Financing Program, Trade Tax Program, and Trade Insurance. The programs are summarized ; First, Trade Financing Program is available to exporters of procuring raw materials and finished goods for export. It is extended with exceptionally low interests from the Korean commercial banks. Second, Trade Tax Program provides whole or part of customs drawback to exporters. customs drawback is' made when exporters meet requirements of Customs for export. Third, Trade Insurance Program cover risks of uncertainty which is beyond the exporters' capacity at low insurance premium. It is suggested that the exporters have deep knowledge of these three programs to their ends. Especially Trade Financing Program and Trade Insurance Program can be a combined work for the financially weak SMEs. Further, there are rooms for these programs to develop to enhance the competitiveness of SME exporters.

According to the second plan of the Korean Government about technology development, utilization and population of new renewable energy, the continuous growth of distributed resources are expected. But if those are interconnected with distribution system, there are many problem. In this paper, it is searched the biggest capacity of distributed resources under limit of actuating current o# protection devices and scheme.

The annual expenditure on diesel oil and heavy oil in the construction sector is the second largest among all industrial sectors. To meet the government's greenhouse gas reduction targets, the construction sector has until 2020 to cut its emissions by 7.1%. Unlike other high-tech industrial sectors, the construction sector has a fairly limited scope for technological improvements, which hampers its capacity to achieve the reduction target. To reduce emissions, it is necessary to establish an energy and emissions strategy at the project planning stage, and energy use and the resulting emissions must be estimated. This research aims to establish an estimation methodology for greenhouse gas emissions at the planning stage of construction projects. To estimate the project-related emissions, this research indentified the relationship among the types of emissions in a cross-sectional matrix form, and then provided a set of calculation methods for total project related emissions.

Railway system which has latent loss of lives and property by big accident with that human error such as locomotive driver, manager, signaller, and the others involved. So human error management is needed to control this complex system and to confirm safety of it. Rail human error research for managing human resource has grown rapidly in both quantity and quality of output over the past few years. The continual influences of safety concerns, new technical system opportunities, reorganization of the business, needs to increase effective, reliable and safe use of capacity, and increased society, media and government interest have now accelerated rail human factors research programmes in several countries. The objective of this research is to improve safety and to reduce accidents in korean railway system, through the application of research results to the investigation of requirement for human error.

Algeria is a country with a high seismic activity. During the last decade, many destructive earthquakes occurred, particularly in the northern part, causing enormous losses in human lives, buildings and equipments. In order to reduce this risk in the capital and avoid serious damages to the strategic existing buildings, the government decided to invest into seismic upgrade, strengthening and retrofitting of these buildings. In doing so, seismic vulnerability study of this category of buildings has been considered. Structural analysis is performed on the basis of site investigation (inspection of the building, collecting data, materials, general conditions of the building, etc), and existing drawings (architectural plans, structural design, etc). The aim of these seismic vulnerability studies is to develop guidelines and a methodology for rehabilitation of existing buildings. This paper will provide insight to the vulnerability assessment and strengthening of the telecommunication centre, according to the new code RPA 99/version 2003. Both, static equivalent method and non linear dynamic analysis are performed in this study.

According to the second scheme of the Korean Government about technology development, utilization and popularization of new renewable energy, the continuous growth of distributed resources are expected. But there is a few paper about recloser and sectionalizer coordination and protection scheme in distribution system interconnected a number of distributed resources. In this paper, it is dealt with that recloser and sectionalizer coordination at the cases concerned with position among protection devices. Adding distributed resource, the problems of each case are investigated through simulation.
