Sometimes, there exist many alternatives for doing a SOC project. However, the limitation of the fund requires the determination of investment priority for the alternatives. This may be performed according to the degree of importance of individual alternatives. Especially, the river improvement project at the downstream of dams has complex and various values and this characteristics make it difficult decision-maker to do reasonable determination. This study aims to determine an investment priority of 33 alternatives in the river improvement project at the downstream of dams using PROMETHEE method which has advantages in determining the priority. In this study, we determined evaluation criteria and attributes by considering the functions and objectives of the river improvement project at the downstream of dams. The eigenvector method in AHP was used to estimate the relative importance of evaluation criterion. Based on the estimation, we determined investment priority of 33 alternatives by PROMETHEE method and the priority of alternatives was derived in the order of Juam regulation dam, Unmun dam, Yongdam dam and so on. The results of this study could provide a reasonable standard to the decision-maker for the determination of investment priority of alternatives.

This study is for figuring out major components of construction quality infrastructure and suggesting improvement plan by benchmarking global best practice model and analyzing gap between the model and sample practice. Based on improvement plan, researcher could derive major characters and components of construction quality infrastructure, and also about the priority among core competency components of construction quality experts. The result showed that the 'human resource' was ranked the best priority followed by 'method' 'environment', 'equipment' among major characters and components of construction quality infrastructure. Also, for core competency components of construction quality experts, 'number of years in work places' was the best priority, and the 'professional knowledge on engineering' was another priority ranked. Far from general perception on competency components, 'academic education' ranked the last. It may allude that the current education system in this country is not effective in developing competency of quality engineers. In summary, this study shows professionalism of quality engineer is the most important thing in all the components.

This study has the purpose to reveal the differences of residents' satisfaction level & demand of community environment and recognized residents' improvement priority of community environment at 3 complexes at the big city in the provinces. The 3 residential complexes had differentiated developmental concepts; the residence-oriented complex, the residence-government mixed complex with an eco-friendly concept, and the outskirt residence-industry mixed complex. Followings are the results of the study. 1) The satisfaction of residents in the community environment correlates with the increasing convenience facilities after construction. In the new outskirt complexes of smaller cities, dissatisfaction occurs more with public transportation rather than the road system, so that efficient public transportation systems, inner and neighboring areas, is requisite. 2) Even in the residence-oriented complex, the education environment does not entirely account for satisfaction level; the green environment is also second in priority after the education environment. In the residence-government mixed complex with an eco-friendly concept, a good natural environment does not entirely account for satisfaction level; education environment is also second in priority after the natural environment. The supply of sufficient schools may be fulfilled in the ways of reform of the education zone with neighboring existing residential areas. In the outskirt residence-industry mixed complex of smaller cities, priority was placed more on the location and convenience; this explains the complex's poor access to downtown.

Purpose: This study is on the priority for improving students satisfaction in university educational service. It explores the dimension of service quality and analyzes the relationship among quality elements, service satisfaction, and loyalty. Methods: This paper performs empirical studies by questionnaire survey. The Timko model is used for finding the degree of possible improvement of quality elements, and structural equation and regression models are used to analyze the effect of them on service satisfaction and loyalty. Also, explanatory factor analysis is used to investigate the quality determinants. Results: The quality dimension is composed of curriculum, employment support, interaction with outsiders, start-up support, learning support, counselling, and administration service. Curriculum, learning support, and administration service are positively correlated with service satisfaction, and service satisfaction has a positive effect on loyalty. Counselling service is an attractive element, and curriculum, start-up support, and learning support are indifferent elements. Conclusion: Comprehensive analysis shows that curriculum, academic advisor, and administration service have high priorities for improving educational service satisfaction.

The works of preparing for missile flight test are becoming more complicated. To reduce the amount of waste time along with the complexity of the task, systematic analysis of waste factors should be performed before performing process improvement. The waste factors for missile flight test are first defined using lean-based waste factors. The improvement priorities for the defined waste factors are surveyed. For reliable analysis, AHP is used in questionnaire analysis instead of the existing method with large error. Then weighting and priority for waste factors for level 1 and Level 2 are suggested. Through AHP, we could derive reliable improvement priorities for waste factors. It is analyzed that the biggest cause of waste factors is waiting time and identified as the first item to be considered when establishing improvement plan. In addition, suggestions for improvement measures of waste factors are presented through brainstorming method. Reliable results will be an important factor in process redesign for missile flight test works.

This paper proposes an application methodology of AHP(Analytic Hierarchy Process) based decision making theory for improvement priority by assessment of various risk factors affecting on deterioration of water supply systems, as major social infrastructure. AHP method is organized with three level of hierarchy which is introduced for multi-criteria decision making in this study. In the first level, assessment outputs are calculated by AHP for each affecting factor. In the second level, criteria are estimated by using assessment results with respect to structural and environmental factors. Consequently, ranking decision is performed in the third level. In order to present the effectiveness, a proposed method is compared with FCP(Fuzzy Composite Programming) for decision making. Since the results of the proposed method show better performance with consistent results, it can be applied as an efficient information for the determination for improvement priority of the study infrastructure.
