There are many positioning studies utilizing Analytic Hierarchy Process (AHP) in tourism industry. In this study, it was tried to develop new evaluation criteria for positioning and to discuss the importance of evaluation factors, as the development of tourist's spots was pursued in diversified ways. The purpose of this study was to allow the development of tourist spots more objectively and more efficiently utilizing Analytic Hierarchy Process ("AHP" hereunder) to appoint the best place for the tourism complex in Buyeo. According to AHP analysis procedures, 5 places near Baikje Cultural Block connecting with a ferry in Buyeo-gun were selected as candidates. To perform AHP analysis, evaluation criteria and a survey were used and then weight of evaluation criteria was induced. With the conditions on criteria, standard score of each criterion and candidate was calculated. By multiplying standard score and final weight and then summing up, the candidate place with the highest score shall be appointed as the most optimal place for Buyeo-gun Agricultural Tourism Complex.

Administrative Role-Based Access Control(ARBAC) is a typical model for decentralized authority management by plural security administrators. They have their work range on the role hierarchy. A problem is that legal modification of role hierarch may induce unexpected side effect. Role-Role Assignment 97(RRA97) model introduced some complex integrity principles to prevent the unexpected side effect based on geometric approach. We introduce simple and new one integrity principle based on simple set theory. It is simple and intuitive. It can substitute for all integrity principles of RRA97 model.

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 read performance of hybrid hard disk is better than the legacy hard disk and power consumption is also considerably low. As blocks with enough localities may be located in the non-volatile cache whose size is generally limited, an effective block replacement scheme is required. As this replacement is inevitably affected by various parameters, we define this issue as a kind of multiple criteria decision model. To solve this problem, this paper suggests a new block replacement algorithm based on the analytic hierarchy process. Through simulation for our model, we confirmed that the proposed model could be used as a replacement algorithm of the hybrid hard disk as it may improve boot time as well as response time of general applications.

Railway line segment deterioration can be affected by rail tracks, subgrades, bridges, tunnels, and line shapes. In this paper, an evaluation method is presented for the railway line segment deterioration using the analytic hierarchy process (AHP) and data envelopment analysis (DEA). The importance weights can be assessed systematically for component facilities from numerous experts using AHP. The importance weights provided by experts may differ according to each expert; however, the DEA enables the evaluation of railway line segment deterioration that reflects the variety of expert opinions using these importance weights.

In this study, we tried to evaluate the relative importance and find out the differences in consumer perceptions regarding service recovery strategies and the service provider in the distribution industry by using AHP (Analytic Hierarchy Process) analysis method. Therefore in this study, we tried to systematize various recovery strategies which were considered very important during service failure process in the distribution industry and analyze the relative importance for each recovery strategy. We set hierarchy composed of four items of monetary, action-oriented, psychological, and assured level as primary selection criteria and a total of 16 items(indemnity, refund, gift, gift certificate, prompt resolution, exchange, manager support, explanation, apology, empathy, acknowledge, kindness, assortment, after service, manage subcontractor, manage employee) as secondary selection criteria. We tried to take one step further from the service sector and study service recovery strategies specialized in distributor services. This study suggests various implications about service recovery strategies of distributors. First, this study can provide practical implications - e.g. service recovery efforts should be applied differently depending on service channels. There is a perceptual difference with respect to the importance of the types of service recovery strategies between service provider and final customer. Second, we can find theoretical implications in terms of identifying the priorities through hierarchy design of new recovery strategies and comparison of each element from the classifications of the current fractional recovery strategies. We hope to help service providers to build more efficient recovery strategy system based on the results of this study.

A big success of the 3D film 'Avatar' in 2009 opened a full-fledged 3D movie era. A new industrial possibility of 3D contents was predicted in Korea and then the support for 3D contents production took placed via various media platforms. Korean government also announced the new development policies with a focus on 3D content. However, the 3D content industry has not been activated. Therefore, in this study by applying AHP(Analytic Hierarchy Process) method we tried to grasp the reason of the deactivation of 3D content industry through analyzing the relative importance rate of three research factors(content aspects, technical aspects, and policy aspects) that were mainly considered to activate the industry. The results of this study showed that the relative importance rate of content aspects was higher than that of technical aspects and policy aspects. It means the lack of 3D contents is one of main reason causing the delay of 3D industrial activation. And it also showed that the relief of human factors such as visual fatigue evaluated as a sub-factors of technical aspects are challenges to be solved soon..

The advancements in technology which have lead to higher and higher levels of integration have required advancements in the methods used in designing VLSI chip. A key to enable a complicated chip design is the use of hierarchy in the design process. Hierarchy organizes the function of a large number of transistors ito a particular, easy-to-manage function. For these reasons, hierarchy has been used in the design process of digital functions for many years. However, there exists differences in a design analysis phase, especially in timing analysis, due to multiple views for the same design. In timing analysis of the hierarchical design, every path is analyzed within partitioned modules independently and the global timing analysis is applied to the whole design considering each module as a single timing component. Therefore, timing results of the hierarchical design could not be same as those of non-hierarchical flat design. In this paper, we formulate the timing problem in the hierarchical design and analyze the possible source of timing differences. We define a new terminology of "consistent result" between different views for the same design. We also propose a new partitioning algorithm to obtain the consistent results. This algorithm helps to enhance the design cycle time.
