Recently policy coordination and integration have emerged as core challenges as complexity and uncertainty of policy. Especially as innovation and environment policy is expanding and its position is being further elevated within policy hierarchy, policy integration has emerged as core governance challenges for nation states. OECD countries emphasized the need of coordination and integration of policy by introducing concepts such as 'Environmental Policy Integration', 'the Third generation innovation policy', 'integrated innovation policy'. This study analysed the background, concepts, objects, mechanisms, and major issues of integrated innovation policy and various attempts for integrate innovation policy by policy level and cycle. Developing integrated innovation policies has become increasingly important for the EU and OECD countries in recent years. OECD countries including Finland have developed broader policy agendas for balancing policy objectives and aims of other policy sectors and horizontal relationships with other policy sectors. Policy integration helps to reorient policies where related policies are in conflict and to ensure coherence across different policy areas. Policy integration emphasizes long-term policy adjustment and adaptation based on social agreement and common vision.

The purpose of this study was to analyze the relationship between the locational characteristics of areas surrounding oriental medicine hospitals and the number of patients who visited study hospitals. Administrative data collected from the annual report of 5 ward offices in Daejeon used to assess the geographical attributes. Two oriental medicine hospitals operated in Daejeon provided data for the number of inpatient and outpatient. Number of patients who visited study hospitals was calculated in each Dong which is the smallest administrative district. The geographical attributes of Daejeon were evaluated by the demographic and economic factors which were assumed to influence the health care demand. Each criterion was measured from each Dong. Weights of factors was calculated by Analytic Hierarchy Process (AHP) method. Evaluation scores which representing the geographical attributes of Dong was computed by multiplying the eight factors and weights. Results showed positive correlation coefficients between the evaluation scores of Dong and the number of patients. One hospital which was more closely located to areas with high evaluation scores had higher number of patients than that of the other hospital. Buffering analysis with varying size support the analysis results. This finding proposed the importance of location for the management of oriental medicine hospitals in a metropolitan city. Applying study model to other cities will enhance the validity of study results.

By applying the AHP(Analytic Hierarchy Process), we have analyzed the importance and the order for priorities to the management risk factors of Korean SMEs & Venture companies in China. The major management risk factors of manufacturing companies were the rise in labor costs followed by fierce competition in the marketplace, problems involved with human resource management and the rise in the cost of materials. In the case of companies manufacturing electronic products, the rise of labor costs and alteration in government's tax policy were seen as the main risk factors. In the case of chemical product manufacturing companies, the reinforcement of environmental protection law and in automobile component manufacturing companies, apart from the rise in labor cost, the increase in raw materials costs were analyzed as the main risk factors. While considering the time period, the main risk factors of the companies that entered China in the 1990's were fierce competition and alteration in government's tax policy and for the companies that entered China in the 2000's, increase in raw material cost, the rise in labor cost etc were analyzed to be the main risk management factors.

Various dimensions of watershed structural/non-structural planning can be applied in comprehensive flood mitigation plan in a river basin. Especially structural counterplans have very broad and diverse nature as flood control facilities. It is not easy to find the optimum alternative to maximize the ability of a basin to reduce flood risk using a combination of structural counterplans. In addition, there is no standard for evaluating the performance of structural counterplans and for selecting optimal combination of them. This study focused on how to select the best alternative of a comprehensive watershed structural plan from various flood defense alternative candidates. By introducing an analytic hierarchy process, we would like to show how we decide the best alternative using standard worksheets developed in this study for economics and policy evaluation, and Expert Choice 11.5, which calculates weights for evaluation items. Based on the results from this study, we would like to suggest the best practice of a standardized watershed plan for flood protection.

This study is to estimate the factor weights for a successful sea-ranching project using the Analytical Hierarchy Process. Furthermore, it investigates the policy implications revealed by the differences in group opinions throughout fishermen, government officials, researchers and the scholars when the weights are assessed. The hierarchy is constructed for the 3 levels of factors which must be evaluated for a successful sea-ranching project. The top level of factors is divided by the ecological factors and the socioeconomic factors. As the middle level of factors, there are 3 factors such as the choice of fish, the habitat environment and the production technology under the ecological factors and another 3 factors such as the stability of fishery society, economic factors, and the law & system under the socio-economic factors. And then, at the bottom level of the hierarchy, the economic factors have two different sub-factors such as the fishing revenue and cost. The law & system has also 3 sub-factors such as the accessibility to sea-ranching area, fishing method, and surveillance. The fishermen and government officials show us quite opposite tendencies in assessments of the weights while both the researchers and scholars reveal almost the same opinions positioned at somewhere between first two groups. The study also reports the evaluations of efficiency measures for resource recovery methods among the sea-ranching project, artificial reef, release of fish seeds, and marine protection area. Both the sea-ranching project and marine protection area have the same efficiency in terms of resource recovery while the artificial reef and release of fish seeds are revealed as somewhat less efficient methods comparing to the former two methods.

The current exploratory study presents the Analytical Hierarchy Process (AHP) as a potential decision-making method to obtain the relative weights of alternatives through pairwise comparison in the context of hierarchical structure. The aim of this study was to elicit prior strategy to improve army military foodservice. Content analysis and seven times of in-depth interview from 13 officers of the Ministry of National Defense were conducted to develop the hierarchical structure for AHP analysis. Questionnaires were distributed to 61 foodservice managers and 39 dietitian and military foodservice officers. The highest-ranked strategy for improving military foodservice was the 'renewal of the kitchen facilities' (0.2578), followed by 'enlargement of foodservice operating staffs' (0.2345), 'specialization of sanitation & foodservice management' (0.2222), 'Practical foodservice budget control' (0.1394), and 'menu variety & standardized recipe' (0.1281). 'Enlargement of foodservice facilities' (0.3995), 'increase the no. of kitchen police' (0.3463), 'sanitary & cooking training reinforcement of kitchen police' (0.4445), 'management of foodservice budget by total amount' (0.5043), and 'standardization of mass cooking' (0.3571) were the highest overweight item in each strategy. The study also compared the relative weights of alternatives of foodservice managers with that of dietitians and military foodservice officers. Those two groups revealed some difference in their priority of important strategy regarding army military foodservice. The results of this study would provide the data for making a policy or compilation of the budget regarding army military foodservice.

A mobile device is a handheld device, typically having a display screen with touch input and/or a miniature keyboard and accessible to the Internet. Because mobile devices are innovative and rapidly changing products, consumers are confronted with a decision-making problem to select the best device. This paper proposes an Analytic Hierarchy Process method to assess mobile devices and shows a method to select best mobile devices when purchasing. For this paper, the mobile devices considered as in the AHP model included net-book, tablet PC, smart phone, and camera phone. We derived 6 main criteria and 15 sub-criteria to synthesize the overall priority of criteria and mobile devices. The criterion of convenience in carrying showed the highest rank in the criteria. Although smart phones had the highest priority, the four mobile devices did not show significant differences in consumer preference.

The current available recommendation systems for mobile games have a couple of problems. First, there is no knowing whether they make a pattern recommendation for games that actual users prefer or for games that they are simply interested in. It is also impossible to know the subjective preference of users in a direct manner. An AHP(Analytic Hierarchy Process)-based recommendation system for mobile games was thus developed to reflect the subjective preference of users directly, but it had its own problem since the degree of preference could vary among users in spite of the same scale for their preferable items. In an effort to solve those problems, this study implemented a recommendation system for mobile games by applying triangular fuzzy numbers of the Fuzzy-AHP technique and the independence of evaluation items in the Bayesian Network. The findings show that the proposed recommendation system recorded the highest accuracy of recommendation results and the highest level of user satisfaction.
