The purpose of this study is to find out primary policies for reducing PM(particulate matter) as well as for improving the quality of life. Serious particulate matters cause to diverse healthcare and economy problems including business transactions. Unfortunately, until recently there are very few researches regarding the decision-making process for particulate matter policies. This study has applied the AHP(Analytic Hierarchy Process) method to develop cooperative policy making processes. The upper layer of this hierarchy analysis consists of four parts, i.e., transportation, production facility, living environment, and urban planning management. And each upper layer parts has their own three policies. 25 experts including policy-makers, academic researchers and industrial specialists have decided the primary policies and directions. The most significant PM policy is the mandatory reduction of air pollution and suspension of factory operation in the production industry. The results of this study can lead to guidelines for making environmental policies.

In this study, we developed evaluation indicators of dam rehabilitation considering climate change in order to prepare for safety of aging dam facilities in accordance with changes in rainfall intensity. The validity and appropriateness of each indicator, and the evaluation criteria were selected for quantitative indicators for each detail through domestic and international case studies, literature review, and expert advice. The survey was carried out to estimate the importance of each indicator for dam rehabilitation. The subjective assessment of the respondents was rearranged using pairwise comparison from the Analytic Hierarchy Process (AHP). The reliability of the survey results was evaluated through consistent verification. In addition, a comparative assessment was carried out which evaluated the reliability importance estimation result to refine the criteria to distinguish rating scales between expert and non-expert groups on dam-related fields.

Performance measurement and evaluation is a critical issue in public funded civil infrastructure projects in recent years. As a results, Korean government has introduced the related policies and regulations based on the foreign cases to evaluate public construction projects. However, construction circumstances are different from other countries and the results from adopted regulations are not satisfied. Therefore this research proposes the critical success factors(schedule, cost, productivity, change order, safety, quality) for public construction projects based on previous related research outputs to successfully implement construction performance evaluation. Then, this paper also proposes the weights for the critical success factors. The proposed weights are developed by AHP of construction experts. Furthermore, the paper shows the difference of the weights of the critical success factors by project participants (owner, constructor, engineering, and inspector). This efforts will enhance the ability to develop an effective performance evaluation process and system for public construction projects.

Shipping is a global industry, with 80% of the world's international trade of goods transported by sea. Many countries with large international trade volumes place great importance in developing their shipping industry. Recently changes in the world economy, international trade, world oil prices and other uncertainties have led to increased competition in the world shipping market. This is specially true, along the Pacific coast, where five of the world's major maritime countries, Japan, China, South Korea, Singapore and the United States are located. This paper aims to compare the international competitiveness of Japan, China, South Korea, Singapore and the United States with Port's Diamond Model and AHP analysis. The results of this research give some suggestions for international competitiveness of Chinese shipping industry, is very competitive in quantitative terms but is relatively weak in qualitative terms.
