Yangsan ICD (Inland Container Depot) has played an important role for Busan Port and Korea's port & logistics industries, increasing international logistics competitiveness and containers' transportation competitiveness in Busan region dealing with 1330 thousand TEU in 2005, since its opening in March 2000. However, it is necessary to seek new measures to revitalize Yangsan ICD, since its cargo volume decreased rapidly owing to the opening of Busan New Port and hinterland in 2006. This study constructed an evaluation model using AHP (Analytic Hierarchy Process) and conducted a survey targeting local businesses and persons concerned in Yangsan ICD to seek measures for revitalization. The results suggest that Yangsan ICD needs to switch functions to logistics centers (terminal facilities, logistics warehouse) for revitalization considering its advantage of facility location. Moreover, by extending the utilization period and securing building-to-land ratio, existing and new businesses' stable activity should be guaranteed. Furthermore, utilizing facilities such as the railway station in ICD, an active railway revitalization policy may increase cargo volume. Yangsan ICD should perform its role as an inland logistics depot through the revitalization of railway freight transportation in the national logistics system focusing on road freight transportation.

In this paper we present an integrated methodology for strategic planning in telecommunications standardization. Especially this paper focuses on the method of setting priorities for telecommunications SWAs(Standardization Work Areas) and related SWls(Standardization Work Items). To make a strategic plan for telecommunications standardization in which usually includes prioritization, resource allocation, standardization schedule for each SWA is based on prioritization of SWAs. Our methodology integrated various existing methods including the Analytic Hierarchy Process(AHP) and a modified Delphi technique. Recently, rapid technology evolution in telecommunications fields increases the necessity of developing more and more new standards. Also increased complexity of those technologies makes standards more complicated, more specified and more thick than the past ones. As a result, the number of SWAs and SWIs are being increased constantly. Furthermore, rapid telecommunication environment changes such as deregulation, liberalization, privatization, regionalization, and globalization surrounding standardization bring about new challenges and opportunities. Due to all these trends, strategic planning for telecommunications standardization grows more and more important. To cope with these challenges and also to make the more efficient use of the limited standardization resources including time, financial, human resources, we suggest more logical and rational approach that will be a backbone of strategic plan for telecommunications standardization. The telecommunications standardization planning process involves a MCDM(Multi-Criteria Decision Making) process. The Analytic Hierarchy Process(AHP) is a kind of MCDM approaches. Our method is based on a combination of a modified Delphi technique and an application of AHP(Liberator's spreadsheet model). Analyzed data from Delphi technique is used as inputs to ABP. In addition, we also focus on the technique how to combine group judgments and to handle a large number of comparisons. We present analyzed results including Pilot and Full Scale Survey according to the proposed process. The result of this study will be useful input for telecommunications standardization policy making and practical implementation.

The purpose of this study is to provide basic data for the improvement of the tournament operating environment and effective tournament operation. For the factor analysis, exploratory factor analysis was conducted. Based on this, in order to conduct hierarchical analysis, we've produced and distributed the questionnaire to expert group. And after, with collected data, AHP (Analytical Hierarchy Process) technique was used to analyze relative importance and determinants. As a result, operational factors showed the highest priority among the components of evaluation. And next prior factors are satisfaction of participants, environmental factors and etc. In order to stabilize the operation of the tournament, priority shall be securing the budget. And it is necessary to understand the desire of participants and shall consider characteristics and level of the tournament. In future studies, it will be necessary to make a comparative study through expert group in order to secure the fitness.

Purpose: As declines in the quality of residential environments occur, such as urban heat island effect, tropical night phenomenon, and violations of right to light and privacy due to urban densification and high rise building, these problems are emerging as social issues. In order to improve these issues, design factors which consider environmental aspects must be selected when planning apartment complexes, and ways to reflect them in the planning phase must be explored. Method: In this study, the analytical hierarchy process(AHP) was used to deduce design factors that considered environmental elements during the planning of apartment complexes. Furthermore, the priority and weight for each evaluation index were assessed. The objective was to propose a guideline for planning apartment complexes by finding the best solution for each evaluation index using complex weight values. Result: Floor area ratio was selected as the most important evaluation criterion in the environmentally conscious evaluation index for apartment complex planning. The shape and placement of skylights were selected as the most important evaluation criteria in the sunshine environment for a pleasant residential environment. Ground surface cover design was selected as the most important criterion in the outdoor thermal environment index for improving the microclimate within cities and apartment complexes. Thus, the results of this study can serve as an investigation guideline that concerns policy and regulations, and as reference data that can be used in planning apartment complexes.

Sea level rise due to global warming causes seawater intrusion into aquifers in coastal areas. Seawater intrusion vulnerability index was developed using PSR (Pressure, State, Response) model and analysis hierarchy process (AHP). Coastal regions in Korea, Gangwon-do Sokcho-si, Incheon-si Ganghwa-gun, Chungcheongnam-do Taean-gun, Jeollanam-do Yeosu-si, Jindo-gun were chosen and 14 indicators were selected by considering the humanities, economic, social, environmental aspects. Re-scaling method was used for the standardization of indices and questionnaire survey was performed to calculate weight values for each index. The results showed that Yeosu-si was selected as the most vulnerable region to seawater intrusion. The seawater intrusion index developed in this research can be used to analyze the vulnerable regions to seawater intrusion and to establish a policy to minimize the seawater intrusion problems in coastal regions.

To improve current transportation service, a new Seoul Metropolitan Transportation Administration (Seoul MTA), backed by Korean central government, is on the way of being established. This paper tries to answer questions such as 'What is the best type of organizational formation of the upcoming institute to deliver better, seamless transportation service?' and 'What is the most suitable scope of work of the upcoming institute to achieve the goal?' A group decision making process, a kind of AHP (Analytic Hierarchy Process) was adopted to measure the experts' preferences of alternatives in quantitative scale measurement. To evaluate the alternatives, five evaluation criteria were selected. Among them, it is revealed that 'Improvement of the transportation service' and 'Political & Administrative power to make it happen' are the two most important evaluation criteria over what types or operating costs of the administrations are. When the five evaluation criteria are applied onto the group of alternatives, it yields that a stand-alone organization, which should be independent from upper-level government body, should have an integrated and sole authority on the area-wide transportation system management.

This study analyzes the military and political factors that influenced the Participatory Government's resolution in Wartime Operational Control (OPCON) Transition. The research on key factors in OPCON transition firstly implemented literature research and then increased feasibility through additional use of AHP. The analysis results showed that there was a negative effect for Korean Peninsular Defense in the 'ROK-US Alliance Asymmetry' area, a positive effect to increase ROK-led Capability of Theater Operation in the 'ROK and U.S. Alliance Interdependence' area and a positive effect for Invocation of ROK Self-Defense Power in the 'Interests of Participatory Government's Liberal Regime' area respectively. After applying AHP, "ROK exercise of Self-defense" in the 'Interests of Participatory Government's Liberal Regime' area received the highest assessment, while the "Increasement of North Korea's Threat" in the 'ROK-US Alliance Asymmetry' area received the lowest assessment. This study is meaningful in that it analyzed the key military and political factors in the Participatory Government's resolution of Wartime OPCON Transition using AHP.

Emerging three-dimensional television (3DTV) as a new IT product shows a possibility that television is not for just watching broadcasting, but an attractive tool for applying it to our real life. Three dimensional television is generally more effective and attractive than two-dimensional television (2DTV). But it still needs continuous technological improvement to solve its inherent limitations until many customers decide to purchase 3DTVs without hesitation. Innovative products like 3DTV encounter a quality problem leading purchase decision by customers. Quality is regarded as one of the most important factors affecting customers to adopt and use the product. Furthermore, measuring quality effectively is considerable for the 3DTV research. In this paper, we suggest the Analytic Hierarchy Process(AHP) method for evaluating 3DTVs in a view of quality. We describe quality criteria affecting the 3DTV selection through a literature survey and develope an analytical method for measuring quality. We classify the quality of 3DTV into four types and suggest a concept of the quality ratio as a measurement criteria instead of the quality gap. Though a numerical example, we show how priorities of 3DTV with versatile manufacturers is computed.
