This study suggested a model that can predict a degradation condition over time of two plastic pipes, PE and PVC, which are currently used in the country. This study was analyzed physical characteristics change of plastic pipes by comparison with initial physical characteristics (on the case of new pipes). Since this is dependent on accidents that already occurred, there are limitations that it only decides a priority on improvement based on relative corrosion status rather than precautionary aspects. The comparison results between physical degradation by the deducted performance rating and a conventional numerical scoring method showed that correlation coefficient was 0.67 for PE pipes and 0.86 for PVC pipes, indicating a high correlation. According to this result, it has been decided that the performance rating suggested herein can be applied naturally to the criterion of an improvement decision, which was based on Scoring System. From results of the research, it is expected that a reliable result can be provided to an improvement decision process related to degradation of plastic pipes by comprehensively comparing and evaluating a condition of pipe materials(direct factors) and an environmental impact(indirect factors).

The procedure of present military facility remodeling has many problems at the stage of evaluating the priorities in various remodeling projects which have been caused from lots of corps. These problems have usually happened not only because of the shortage of the cooperation system in the related divisions but also because of the nonexistence of the effective process and method for evaluating the priorities. I've reviewed the study of remodeling and military facility business and applied the AHP(Analytic Hierarchy Process) method which is effective to evaluate the priorities in various groups' decision.

A virtual shopping mall is like a real-world mall, supports electronic shopping by selling products or services through Interne. Although increasing numbers of products are being marketed on the Web, little efforts has been spent on evaluating what mall is more suitable for marketing electronically and for protecting consumers. Evaluation of virtual shopping malls is regarded as a major task in business-to-consumer electronic commerce. This paper considers the Analytic Hierarchy Process(AHP) method in the evaluation of virtual shopping malls and provides its applications. The AHP is a systematic procedure for representing the elements of any problem, hierarchically. A series of pairwise comparison judgments is performed to express the relative strength or intensity of impact of the elements in the hierarchy. The AHP model hierarchy consists of the four following levels: decision maker, main criteria, sub-criteria, and virtual shopping malls. the main criteria include the state of physical firms, representation of information on the virtual shopping malls, product or service, convenience for shopping, consumer protection, and consumer service. The total number of sub-criteria in the third level is twenty-nine. All decision makers selected belong to virtual shopping mall enterprises, or universities. As a case study, we show the synthesized priority of the five virtual shopping malls that have acquired an E-Trust mark. Finally a sensitivity analysis shows how well each virtual shopping mall performs on each criterion by increasing or decreasing the importance of the main criteria.

Automated Guided Vehicles(AGVs) are widely used in computer integrated manufacturing(CIM) systems for material handling purposes. Although automated guided vehicles provide higher levels of flexibility and computer integrability, the installations are limited in number and one of the critical reasons lies in the complexity involved in the operation. The main objective of this research is to alleviate this problem by proposing efficient integrated operational control methods for AGV-based CIM systems. Particularly, this research is concerned with the mixed problem of dispatching automated guided vehicles and scheduling machines operation. The proposed dynamic heuristic algorithm uses various priority schemes and relevant information concerning the load of the system, the status of queues, and the position of AGVs in the scheduling process. The scheduling decision process is hierarchical in the sense that different decision criteria are applied sequentially to identify the most appropriate part to be served. This algorithm consists of two sections, the section of part selection by AGVs for the next service whenever an AGV completes the current assignment, and the section of part selection by machines for next service whenever a machine completes the current operation. The proposed algorithm has been compared with other scheduling schemes using the performance measure of mean flow-time and mean tardiness. Simulation results indicate that the proposed algorithm can reduce the mean flow-time and mean tardiness significantly.

Since the beginning of our military history, we are continuously interested in supplying apartment for military officers. So we possessed 72,361 households and used in 2002 however, $18\%$ of those are over 20years and need to be remodeled Department of Military has taken this fact seriously To solve the problems, they built more new buildings, rent public buildings and remodeled the old one But, The procedure of present military apartment remodeling has many problems at the stage of evaluating the priorities in various remodeling projects which have been caused from lots of corps. I've reviewed the study of military apartment business and applied the AHP(Analytic Hierarchy Process) method which is effective to evaluate the priority in various groups' decision.

Civil proceedings, surveyed results and medical expenses that are evidenced by expert witness are just one of the methods of proof. Since a judge makes decision by synthesizing all evidences on a concerned case, thus the judgement would be different from that of expert witness. It is not rational for medical institutions, of which priorities are medical treatment, to give priority to disability decision. However, despite of its importance, medical institutions less recognize about the necessity of procedural stability and predictability in expert valuation. It is necessary to identify actual problems and investigate rational alternatives to acquire fairness in valuation procedures and accuracy in calculating future medical expenses. Therefore, this research explores the problems and realities of evaluation process in medical treatments, and then discuss the alternatives of written expert opinion and estimation of future medical expenses.

Traffic control is the center of the railway traffic control system. The main objective of railway traffic control system is to minimize delays, providing the customers with on-time train operating service according to the given train schedule. Particularly, within the station control area, the departure & arrival of train. the decision on the train priority and the shunting of train are decided by the authority of the local traffic controller. Therefore, it is necessary to have a lot of information and communications between each departments. And for such decision making of the local traffic controller, not only the communication between each stations are needed, but also the communication between other stations are needed too. In this paper, we have analyzed the main work of the local traffic controller in large scale stations and have designed the station traffic control system needed to be built within the station considering the local traffic. And we have proposed not only the communication with other system within station, but also the communication methods for communications with the neighboring stations.

This study presents the Analytical Hierarchy Process (AHP) as a potential decision-making method for obtaining the relative weights of alternatives through pairwise comparison in the context of hierarchical structure. The aim of this study was to elicit prior strategies for brand communication for Korean restaurants overseas. We created a questionnaire and surveyed experts at government agencies, restaurant companies, and universities from October to November 2011. By applying the pairwise comparison matrix, relevance was perceived as a more important strategy evaluation criteria than effectiveness or urgency. The highest-ranked strategy was the 'Identification of the BI and positioning of Korean restaurants' followed by 'Development of Korean food content for overseas promotion', 'Development of locally customized Korean food recipes and new Korean menus', 'Development of marketing communication strategies for Korean restaurants by countries', and 'Development of Korean restaurant differentiation strategies'. The results of this study can be used for effective Korean food globalization by enhancing the competitiveness in the world market.

The national nuclear R&D projects have been implemented for the purpose of supply of nuclear power which was proved to be safety and stability. Evaluating the national nuclear R&D projects has critical importance in nu-clear energy management aspect. This paper employs multi-attribute utility analysis as a basis for obtaining an evaluation index to assess the national nuclear R&D projects using a specific case study of Korea. To structure and quantify basic values for the evaluation, we elicited important attributes, then refined and structured them into a hierarchy. A multi-attribute index is constructed as a multi-attribute utility function, based on value judgments provided by a group of technical experts, policy makers, and faculties. As a result, the objective of attainment of a proposed object is given the highest priority, followed by appropriateness of project and research strategy, utilization of research output, within attribute ranges defined for the attributes. We found that the work and results of this study can provide valuable insights and decision opportunities for virtually all major decision making in evaluation of the national nuclear R&D projects in Korea.

There are three things that are not known to the human being. That is when, where and how one will die. Most people live ignoring death. However, elements of death linger everywhere. The purpose of this treatise is investigates about justification Deciding for Other directions. First, I will investigate about Deciding for Other directions, when patient can not decide own, I will do investigate agent's decision's problem. Second, These four principles provide the common ground for biomedical ethics. Principlism argue that a method using four principles can resolve controversies in bioethics. The method holds that there are four principles-respect for autonomy, nonamleficence, beneficence, justice- that articulate the necessary conditions of common morality for health care and bioethics. Beauchamp and Childress respond by arguing that the two problems are nc the meaning or interpretation but the process of specification. Third, So, Supplement four principles' problem to Levinas concept of the Other theory. Levinas concept of the Other is very resemblant with 'Love your neighbour as yourself." Christians believe that Love is above all and they act accordingly. They base this faith mainly upon the motto of "love your neighbour as yourself." Fourth. difficult part of Levinas concept of the Other is that there is no human to equal infinite sense of responsibility. Can be supplemented about this through cooperation of community. Four principles can be brought to bear on moral choices. And they asserts that each principles has weigh but they do not assign a priority weighting of ranking. All the principles are equal in moral decision making.
