국가하천의 주변지역을 체계적이고 계획적으로 조성 이용하여 난개발을 방지하고 지속가능한 발전을 도모하며, 그에 따른 이익을 하천의 정비 및 관리 등에 활용함으로써 공공복리의 증진에 기여함을 목적으로 하는 친수구역활용에 관한 특별법이 곧 시행될 예정이다. 친수는 단순히 하천 보전과 상대되는 수변이용의 측면이 아니라 하천의 경관, 생태계, 물 등 전체적인 하천공간에서 이루어지는 인간의 활동과 심리적 만족감으로 해석할 수 있다. 이러한 친수활동 유형을 정립하기 위하여 전문가 및 실무자들의 도움으로 설문지를 작성하고, 조사하였다. 또한 평가 항목간의 중요도를 합리적으로 부여하고자 전문가 집단 활용을 통한 다기준의사결정 기법 중 계층분석과정 AHP(Analytic Hierarchy Process)와 이의 일반적인 형태인 ANP(Analytic Network Process) 기법을 이용하여 비교 분석하여 보았다. AHP는 의사결정의 목표 또는 평가기준이 다수이며 복합적인 경우, 다수의 속성들을 계층적으로 분류하여 각 속성의 중요도를 파악함으로써 최적 대안을 선정하는 기법으로 다수의 목표, 다수의 평가기준, 다수의 의사결정주체가 포함되어 있는 의사결정 문제를 계층화하여 해결한다. 그러나 의사결정 문제는 대부분 요소들 간의 수평적 상호작용과 수직종속성이 존재하기 때문에 단순히 계층적 구조만으로는 설명할 수 없는 경우가 있다. ANP는 AHP 분석을 확장한 개념으로 평가 요소가 계층구조를 가지고 있으면서 각 평가 요소간 네트워크 구조를 가지는 경우에 해당한다. 즉, 시스템 분석, 통합 및 조정을 위한 방법으로 요소들 간의 비선형 관계를 모델화하는 복잡한 의사결정에 적용이 가능하다. ANP는 AHP의 기본 공리인 독립성이 유지되지 않을 때도 적용할 수 있는 의사결정 방법이기 때문이다. AHP와 ANP 분석을 위해 평가기준은 하천특성, 생태환경특성, 인문환경특성, 경관, 유지관리 등으로 분류하였으며, 세부평가항목은 하천의 물리 생태학적 특성, 개발여건과 관련된 특성, 경관의 이용가치, 유지관리 용이성 등 20여 개로 나누었다. AHP와 ANP를 이용하여 친수공간 이용지수 가중치를 산정한 결과, 두 기법은 큰 차이를 보이지 않았다. 그러나 ANP를 이용하여 가중치를 결정하는 방법은 최종 결정의 공정성이나 신뢰성을 확보하는데 기여를 하는 것으로 나타났다.

Although the telecommunications service industry has become a basic infrastructure component of the information and communication technology (ICT) industry, it is now losing its reputation as a cash cow due to achieving a saturation of service subscribers, especially in South Korea. With the exception of improving network speeds, network operators are experiencing difficulties in creating new innovations. Therefore, new innovations for the telecommunications service industry should be identified in conjunction with government policies for industry promotion. To examine the innovative capabilities of a specific industry, innovation system theories were used as a framework for research. However, existing innovation systems are limited with regard to explaining the openness of relationships and user participation which are general properties of the ICT industry. Moreover, as sources of innovative activity, additional values such as financial support and collaboration are more appropriate. This study presents a new innovation system based on innovation values. We analyze the telecommunications service industry and prioritize the importance of telecommunication policies within South Korea. An in-depth interview with experts based on the innovation system framework is conducted first. Next, innovation factors derived from the interview are applied within an analytic hierarchy process (AHP), leading to a prioritization of innovation factors for the telecommunications service industry.

Association of South East Asian Nations(ASEAN) has recently decided to develop ASEAN Highway Network to connect member countries by road in an attempt to achieve a goal of closer economic integration in the region. This entailed the necessity to newly construct or upgrade some 5,481 km of road sections to make ASEAN Highway Network functional. This study offers haw we can prioritize development of these road sections using the Analytic Hierarchy Process. Particularly, it shows how individual road sections can be prioritized considering the importance of corridor or road group where the individual road section lies. It also develops how values of different evaluation criteria can be compared in the same scale. This new approach can be useful in prioritizing highway development in such cases where candidate road sections are widely scattered around the region, so detailed benefit and cost analysis is practically too demanding to carry out.

It is necessary to understand and apply the concept of Quality of Service(QoS) for the objective selection among the computer network equipment. Because ITU-T E.800 recommendation covers the service quality of provider's viewpoint and the satisfaction of user, it can be used to evaluate and select the product of computer network systems. This paper is concerned with the development of an evaluation model using QoS and software tool for selection of the most suitable LAN switch. We apply the Analytic Hierarchy Process(AHP) method of Saaty which has been in a multiple criteria framework for an effective group decision process to the selection of LAN switch. The sample data are collected and processed from a questionnaire of professionals in the network field. And we implement a prototype tool for the selection of LAN switch according to the suggested selection model and analyse the result. The result of our research is expected to be a useful tool for decision making to evaluate and select the LAN switch and also can be applied to the decision making of evaluation and selection related to the product of computer network with QoS.

It is an urgent problem that Korea logistics enteprises' expansion of advance into China market and the logistics network establishment between Korea and China to back up the former are to be solved. Accordingly, the purpose of this study is to deduce the subjects to establish the logistics network between Korea and China, and to evaluate the priority order. The results of this research are as follows: First, we conducted face-to-face interviews on the advisery group in China and Korean enterprises which advanced into China, and drew out 6 promoting subjects to build the logistics network between the two. Second, the AHP model was adopted, which is a multi-criteria?multi-hierarchical decision making method, to draw out the weight and priority order of the deduced 6 promoting items. Third, the resultant priority order of the promoting subjects is as follows: No.1 - to establish the distribution & logistics support center by region(0.3900); No.2 - to support various taxes in investing the logistics business abroad(0.1980) ; No.3 - to improve the management of CIQ(0.1958); No.4 - to back up the joint-venture of logistics firms(0.1169); No.5 - to enhance trade and foreign policies to deregulate the entry into logistics markets(0.0536); No.6 - to construct the logistics information system of China(Northest Ssia)(0.0458). This paper resulted in finding out Korea logistics enterprises that have not secured their own inland-transport network in China and the actual difficulties of Korean enterprises with using the inferior network that advanced into China. These problems were developed into the analysis adopting the AHP method, and the significancy of this paper is to present the priority order of promoting problems using a sophisticated technique.

The purpose of this study is to develop an evaluation system for integrative comfort values of Hanok residence. For this study, a mock-up located in Yongin, Gyeonggi province built by an ongoing governmental research project has been chosen. Then, SSN (Smart Sensor Network) has been utilized for monitoring quantitative factors in the environment and detailed face-to-face surveys have been performed for analyzing qualitative comfort indexes from residents in the experimental settings. Then, this study employs a combined evaluation system using AHP (Analytic Hierarchy Process) established for estimating overall DIC (Degree of Integrative Comfort) of the Hanok residence. As a result, the evaluation system could verify the total comfort indexes of Hanok residence and suggest converged methodologies for establishing value assessment system for traditional residential facilities. The method of DIC suggested in this paper would be examined with current residents in a built mock-up to see its applicability as a comprehensive evaluation model, and it is expected that collected year-round comfort data from the facility would provide more practical information towards future strategies for the Hanok residence.

Recently, the interoperability has become more important to enhance the net-centric capabilities of the warfighter. DITA (Defense Information Technical stAndard) is the set of IT standards for improving interoperability, scalability, effectiveness, and efficiency. In this paper, we analyzed the standardizing process to derive the selection criteria and structurized the derived selection criteria using the KJ (Kawakita Jiro) method. Finally, we developed an evaluation model for selecting a standard for DITA using AHP (Analytic Hierarchy Process). As a result, we present eight selection criteria (maintainability, trend, stability, portability, effect of other standard, constraint of the network, and applicability to the systems). We also applied some examples that several IT standards to our selection model for validating the model. We expect our model to help to decide objectively whether the new standard can be listed in DITA.
