According to the aging, the medical device industry is focused as a future promising industry. However, Korea medical device industry is not enough market competitiveness due to a narrow domestic market and a small company structure. This study aims at evaluating medical device priorities following 3 steps. First, we classify the medical device into three hierarchy categories and AHP survey was conducted on 30 experts in order to extract medical device priorities. Second, priority scores of medical device are analysed using AHP and Fuzzy-AHP. Third, a most important medical device is selected by comparing the volume of medical device manufacture and priority scores. As a result, 'dental implant' is the most import medical device, and we suggest a strategy based on a positioning map. The proposed methodology will provide a inspiration for establish of R&D and support policy in the medical device industry.

The category for waterproofing is one of construction process most affected by falling-off in price competitiveness, construction quality, and material performance. Therefore, in order to select of waterproofing construction firms, it is necessary to consider Incorporating both price competitiveness and construction quality. In this article, I would like to analyze 10 Factors for Selecting using fuzzy-AHP model, including the survey of the waterproofing experts. This fuzzy-AHP model can be shown to calculate the fuzzy trigonometrical function to reflect weights for preference of 10 factors for the waterproofing construction firms. It was found from the result that waterproofing construction firms was searched order of priority for select by fuzzy-AHP model.

This study aims to find the main factors to influence consumers' purchase of dairy products. To do so, we examined experts' opinions to verify the priorities of the factors. The four main factors were derived from the previous studies, product factor, marketing factor, quality factor, and social factor. Using analytic hierarchy process (AHP), we empirically analyzed and tested the results from survey. Based on the AHP analysis, the expert group recommended to improve the packaging, brand, and shelf lie of dairy products for the marketing factor, for instance. The results of this study can contribute to the development of the dairy products for the future to reveal the importance of the selecting factors.

Domestic residential buidling grading is currently comprised of 5 fields; sound-proofing, structure, ambient condition, living environment and fire-proofing. However, factors the take up most of the civil complaints are related to leakage, and waterproofing is not listed as part of the grading system. In particular, the Ministry of Land and Transport claims that the most crucial problems are leakage related in residential structures. Therefore, this study proposes to provide such grading system for waterproofing by AHP methodology based on waterproofing application locations in residential structures.

The purpose of this research is to identify the major evaluation criteria of IT investment projects and establish the importance weights of criteria through AHP analysis. Seven evaluation criteria which have been drawn from prior studies and industry practices are direct costs, indirect costs, financial benefits, strategic value, risk, technical necessity, and political considerations. Data have been collected from 95 IT projects in 40 public organizations and private firms in Korea. After having applied the data reliability test, 79 projects have been selected. The results of AHP analysis show the importance weights and priorities of seven evaluation criteria as follows: financial benefits 25.2%, strategic value 22.36%, direct costs 14.34%, risk 12.10%, technical necessity 11.55%, political considerations 8.3%, and indirect costs 6.48%. And the weights of seven criteria shows considerable differences among three different IT project types such as transactional, informational, and infrastructural.

During drought, there have been a number of conflicts because of the limited and insufficient water to allocate for the numerous water users. To solve the problems, the decision on the priority of water use should be made with social rationality A rational and systematic procedure needs to be implemented in order to decide the priority of water use. First, a criteria level is made of the main and detailed drought impacts which come from the economic, environmental, and social aspects. Four alternatives are then identified for priority of water use. Second, survey to the two group(professional, residents) has been done with using pair wise comparisons. Finally, the relative weights and the priority of alternatives are determined by means of the Analytic Hierarchy Process(AHP) which is one of the Multi-Attributed Decision Method(MADM). By using AHP, it has been concluded that the water allocation during drought should be accomplished in order of domestic, irrigation, industrial, and river maintenance water. If the AHP method were improved for inconsistency which may be generated with survey analysis, a number of applications will be used for the solutions of problem in water resources systems.

To solve the problems of traffic congestion, air pollution and energy derived from increased car consumption, people are in recognition of the importance of green mode, bicycle. Bicycle use rate in Busan is lower due to the terrain and limited public transportation accessibility. Therefore, geographical conditions and use activation should be initially considered in the bicycle route planning. We calculated a weight using AHP(Analytic Hierarchy Process), make a database using GIS tool and deduced the routes applying calculated weight in this study. The result of this study, We could get reliable data as inspecting consistency of the research. Routes are deducted in the place where using demand is higher than arbitrarily chosen routes. Therefore, the route planning through AHP is expected to be utilized in area-specialty-reflected route planning or bicycle road alternatives testing.

It becomes easy to acquire operating qualification of remote control tower crane and illegal retrofits is increased, remote control tower crane models are increasingly being used in smaller construction sites. However, as the problems caused by tower crane operators who have shortages of operating experience grow, safety accidents is increasing and worker is exposed to risk of accident. In this study, the cause of the accident was derived by analyzing the cause of the remote control tower crane accident. And then, the significance of accident causes was analyzed by AHP technique. The result of this study is that tower crane operators and construction workers do not comply with work rules.

The supply of public libraries in Korea has been rapidly improving because of the recent increase for cultural demands and revitalization of the local culture. This paper aims to analyze the efficiency about 565 public libraries using Clustering DEA/AHP(CDA) model. This model is employed the efficiency analysis in order to incorporate project irreversibility and division due to the limit of resources spending. The results shows that the public libraries are divided into three groups which are large size libraries(Group 1), middle size libraries(Group 2) and small size libraries(Group 3). Their average efficiency was found as 0.89, 0.72 and 0.60 each.

The ministry of security and public administration provide the secure coding guide that can remove the vulnerability of applications and defend cyber attack from the coding step because cyber attack like the hacking about 75% abusing the vulnerability of applications. In this paper we find the oder of priority and did the criticality analysis used by AHP about 7 items in the secure coding which the ministry of security and public administration provide. The result is decided that 'exception handling' is the most important item. There is no secure coding items in software supervision currently, therefore the result of the research will make good use audit standards in the process of the software development.
