온라인 서명검증을 위해서는 서명의 국부적인 형태가 중요한 판단 근거가 된다. 함수적 접근이나 매개변수적 접근과 같은 지금까지의 접근방법은 서명을 시간에 대한 함수로 나타내거나, 특징집합으로 표현함으로써, 서명의 국부적인 모양을 무시한 채로 서명검증에서 유용한 요소로 사용될 수 있는 국부적인 모양에서의 다양한 특징, 국부적인 모양의 변화, 형태의 복잡성 등을 사용하지 않았다. 이 논문에서는 서명을 구성 형태에 근거한 구조적인 표현 방법으로 나타내어 서명의 국부적인 모양의 분석과 중요한 부분에 대한 선택적인 사용이 가능한 새로운 접근방식의 서명 검증 기법을 제시하였다. 즉, 서명의 구조적 표현에 근거하여 국부적 가중치 적용방법과 진위판단을 위한 임계치의 개인별 차등화 방법을 고안하였고, 이에 대한 실험결과를 분석하였다.

The objectives of this research are (i) to review the functional and financial distribution of public health adminstration between central and local governments, (ii) to find out, based on economic criteria, optimal distribution required to fullfil local need for public health, and finally, (iii) to suggest policy implications in health area in face of the newly arising local autonomy system in Korea. Judging from data on government expenditures and tax revenues, public health administration in Korea is highly concentrated into central government, both functionlally and financially. High dependency of public health on central government has often been critisized that local residents can not participate in the decision making process for local health problems. This study, however, shows that localization of public health administration does not necessarily result in efficient and equitable allocation of resource to satisfy local demand for public health. From this point of view, two eccnomic criteria are suggested, i.e. external effect and economies of scle, as distributive criteria of roles in public health administration between local and central government. In addition, superiority of central concentration of public health administration to localization is emphasized in that public health in a wide sense contains the nature of public good and is part of compulsory socil security system. As a consequence, planned intervention by government is desirable.

The purpose of this study is to figure out the current condition of local governments (Si or Gun) to implement rural development policy in the face of the central government's drive for increasing devolution. Since late 1990s or early 2000s when scope of rural policy began to expand quantitatively, there has been considerable increase in rural residents' participation into community projects as a whole. Nevertheless, there exists regional differentiation in local governments' efforts to systematically support rural development projects (CRDP: Comprehensive Rural Development Programme) and community activities by setting up intermediary organizations or hiring rural development professionals in a public office. According to this survey on local government officials, regions that have made such efforts to support rural policy at a local level, show more advanced level of institutional capacity than other regions in local decision making process for CRDP, role of strategic rural developmental plans, vitality of community actors, etc. In the era of increasing devolution, these differences can be expected to result in diverging performances of each area in regionalized rural policy. The central government needs to introduce EU's LEADER-type rural development programmes to support community acitivities by various local actors and at the same time promote local governance building for rural policy, adopting institutional rewarding system such as rural planning contract.

해외직접투자는 기업의 장기적인 성장전략 차원에서 여러 가지 동기를 가진다. 본 연구는 현대자동차의 미국 앨라배마주 현지투자에 대한 사례연구를 통해 우리나라 자동차산업의 관점에서 미국에 대한 직접투자의 동기와 입지선택시의 고려요인을 분석한다. 이 논문은 미국에 대한 수출이 최근 호조세를 지속하고 있는 상황에서 생산원가 면에서 유리하지 않은 미국내 투자가 이루어진 동기는 무엇인가에 대한 문제 제기에서 출발한다. 조사결과 미국투자의 가장 강력한 동기는 대미통상마찰 완화였다. 즉, 수출의 상당부분을 미국시장에 의존하고 있는 상황에서 현지생산을 통하여 자동차부문의 심각한 한ㆍ미간 무역수지 불균형현상을 완화하여 미국과의 통상마찰을 회피하고 무역분쟁의 소지를 줄이고자 하는 방어적 차원의 전략적 동기가 현대자동차 미국 현지투자의 가장 큰 이유였다. 소비자에의 접근성 향상 등 기타 요인은 부수적인 중요성에 머물렀다. 그러나, 국가 단위의 선택이 이루어진 후 local 단위의 선택에 있어서는 여러 가지 입지적 요인들이 종합적으로 고려되었으며, 특히 지방정부의 적절한 인센티브 제공이 중요한 역할을 하는 것으로 나타났다. 이러한 연구결과는 우리나라 제조업의 선진국에 대한 해외투자는 전통적인 해외직접투자 이론으로써는 설명할 수 없는 방어적 차원의 전략적 동기가 중요하게 작용한다는 것을 시사한다. 아울러, 각급 정부단위의 적절한 유인구조 설계가 해외직접투자 유치에 중요하다는 것을 확인한다.

Since degraded region of input image can cause false minutiae which lead to decrease identification performance, use minutiae belong to only good quality to ensure true minutiae. This paper suggests image quality measuring method with respect to local and global orientation of ridges. In order to verify a suggested method, PDFs of quality indices derived by local and global feature are computed and then, classifying each image block using Bayesian decision theory.

This study was designed to examine the effect of joint participation in decision-making on the home management satisfaction of new-generation married women, which will issue basic data for improving the quality of new-generation home life. The sample was composed of 371 married women under 39years old, selected by age and the local distribution. Major findings are as follows. 1) New-generation married women’s joint participation in decision-making showed a significant difference by degree of communication, perception of the adequacy of resources, perception of the level of living. Home management satisfaction shoed a significant difference by state of employment, existence of children, sex role attitudes, degree of communication, perception of the adequacy of resources, perception of the level of living. 2) The more a couple participated in decision-making about eating and children, the higher level a new-generation married women showed in home management satisfaction. 3) The main variables predicating new-generation married women’s home management satisfaction was perception of the adequacy of resources, perception of the level of living, gender role attitudes, existence of children, joint participation in decision-making about eating and children. They accounted for 36% of the variance.

This study is to develop a Priority Decision System for Redevelopment (PDSR) which is able to decide the priority for redevelopment of agricultural reservoirs. The major scopes of this research are to make the related GIS data like hydrologic unit map and other thematic maps to determine the suggested priority index (PI), and to develop the PDSR handling the GIS data and calculating weighing factors for the PI. In order to make the weighing factor decision module, the AHP technique was adopted. The result of the weighing factor calculation was showed PC (Possibility Criteria) and RC (Restriction Criteria) were 76% and 24% respectively. Which means that most of the specialist selected PC category prior to RC because of whom to mostly of major technique. So, in order to make more objective result, the selection of specialists is important like environmental activists or local residents and so on. The product from this research can provide more scientific support to decide the priority decision.

Multi-criteria decision making (MCDM) algorithms play an important role in ensuring quality of service in an integrated HetNets (Heterogeneous Networks). The primary objective of this paper is to develop a multi-criteria vertical handoff decision algorithm (VHDA) for best access network selection in an integrated Wireless Local Area Network (WLAN)/Universal Mobile Telecommunications System (UMTS)/Worldwide Interoperability for Microwave Access (WiMAX) system. The proposed design consists of two parts, the first part is the evaluation of an Analytic Hierarchy Process (AHP) to decide the relative weights of handoff decision criteria and the second part computes the final score of the weights to rank network alternatives using Simple Additive Weighting (SAW). SAW ranks the network alternatives in a faster and simpler manner than AHP. The AHP-SAW mathematical model has been designed, evaluated and simulated for streaming video type of traffic. For other traffic type, such as conversational, background and interactive, only simulation results have been discussed and presented in brief. Simulation results reveal that the hierarchical modelling and computing provides optimum solution for access network selection in an integrated environment as obtained results prove to be an acceptable solution to what could be expected in real life scenarios.

In this paper, a procedure using a genetic algorithm (GA) and a heuristic local search (HLS) is proposed for solving facility rearrangement problem (FRP). FRP is a decision problem for stopping/running of facilities and integration of stopped facilities to running facilities to maximize the production capacity of running facilities under the cost constraint. FRP is formulated as an integer programming model for maximizing the total production capacity under the constraint of the total facility operating cost. In the cases of 90 percent of cost constraint and more than 20 facilities, the previous solving method was not effective. To find effective alternatives, this solving procedure using a GA and a HLS is developed. Stopping/running of facilities are searched by GA. The shifting the production operation of stopped facilities into running facilities is searched by HLS, and this local search is executed for one individual in this GA procedure. The effectiveness of the proposed procedure using a GA and HLS is demonstrated by numerical experiment.
