Recently, XML has been widely used as a standard for a data exchange, and there has emerged the tendency that the size of XML document becomes larger. The data transfer can cause problems due to the increase in traffic, especially when a massive data such as Data Warehouse is being collected and analyzed. Therefore, an XMDR wrapper can solve this problem since it analyzes the tree structures of XML Schema, regenerates XML Schema using the analyzed tree structures, and sends it to each station with an XMDR Query. XML documents which are returned as an outcome encode XML tags according to XML Schema, and send standardized messages. As the formalized XML documents decrease network traffic and comprise XML class information, they are efficient for extraction, conversion, and alignment of data. In addition, they are efficient for the conversion process through XSLT, too, as they have standardized forms. In this paper we profuse a method in which XML Schema and XMDR_Query sent to each station are generated through XMDR(extended Meta-Data Registry) and the generation of products and XML conversion occur in each station wrapper.

Through rail transit has many merits as a safe, environmental harmonic and scheduled transit, there are many problems to construct railroads because of the public resentment. However, there is no reasonable way to settle the conflict properly and it causes enormous social and economic losses. This paper suggests a methodology to evaluate public complaint using the AHP technique, which is generally used as the methodology to evaluate public complaint using the AHP technique, which is generally used as the Multi-Criteria Decision Making (MCDM). However, the result from the AHP has some defects to control conflicts because the interests related to railroad projects are so complex that it is hard to make people persuaded easily. Therefore, this paper suggests 'the improvement ranking method', 'the sensitive analysis', and 'the assessment of independence relationship' which can aid the basic AHP to be robust. And the AHP. modified by fuzzy method, is also suggested to apply this methodology to example rail paths in Korea.

In accordance with the increasing possibility that the new and reoccurring epidemics continuously appearing abroad flow into Korea, it is very important to evaluate the efficiency of quarantine management projects of National Quarantine Station. This study adopted the pairwise comparison approach using the analytical hierarchy process(AHP) that has been recognized with its scientific adequacy for allocating the weight, the relative importance of evaluation components. AHP technique is evaluated to be distinguished in measuring the impact by making hierarchy of, simplifying and systemizing the complicated multi-criteria decision making problems. The weights by evaluation indexes were 0.2 in the organization evaluation field and 0.8 in the service and program field. The quarantine business showed the highest value, 0.45, in the service and program field. The indexes were classified into the upper category (organization evaluation field, service and program evaluation field) and lower category (input/process/result/quarantine field, inspection field, hygiene management field, pathogenic organ investigation and monitoring field, epidemics prevention promotion/education field). The evaluation indexes that were finally selected were applied to the actual businesses in National Quarantine Station. Next, the minimum evaluation indexes were selected and so the evaluation system on the businesses in National Quarantine Station was more systemized.

The purpose of this study is to find out primary policies for reducing PM(particulate matter) as well as for improving the quality of life. Serious particulate matters cause to diverse healthcare and economy problems including business transactions. Unfortunately, until recently there are very few researches regarding the decision-making process for particulate matter policies. This study has applied the AHP(Analytic Hierarchy Process) method to develop cooperative policy making processes. The upper layer of this hierarchy analysis consists of four parts, i.e., transportation, production facility, living environment, and urban planning management. And each upper layer parts has their own three policies. 25 experts including policy-makers, academic researchers and industrial specialists have decided the primary policies and directions. The most significant PM policy is the mandatory reduction of air pollution and suspension of factory operation in the production industry. The results of this study can lead to guidelines for making environmental policies.

In this study, we have conducted a survey of AHP technique through the ocean experts to derive new items and revise assessment items and indices for risk of sunken ships based on the survey results. As a result of the survey, two new items such as accident cause and tidal current are derived. And it shows that existing items such as toxic liquid substance, remaining oil and explosive gas which were evaluated as one group are desirable to be evaluated respectively. Accordingly, we analyze the indices of the new eleven assessment items adjusted from the existing seven assessment items. As a result, the indices are ordered by toxic liquid substance, possibility of leaking, explosive gas, carrying capacity of fuel oil, sensitivity of sea environment, marine traffic environment, cause of accident, tidal current, keel clearance, ship type, and ship size. Especially, as compared with the indices of existing assessment items, the indices of sensitivity of sea environment and possibility of leaking are higher and the index of keel clearance is lower.

예술작품은 의상디자인에 영감 혹은 영향을 줌으로써 상업적 의상으로 재생산된다. 오늘날까지도 60년대의 많은 팝 아티스트 작품들이 그대로 T셔츠 등에 프린트되는 것을 쉽게 볼 수 있다. 이러한 직접적 영향에는 자주 맹목적 표절이라는 논란을 불러 일으켰으나 긍정적이든 부정적이든 예술작품과 의상 디자인은 20세기초부터 밀접한 관계를 가져왔다. Sonia Delaunay는 예술을 대중과 결합시키는 가장 좋은 방법은 의상을 통해서라고 생각하였다. 그녀는 "만일 예술작품을 생활 속에 들어가게 하려면 그건 여성들 자신이 입고 다니는 방법뿐이다". 라고 말하였다. 결국 이러한 예술의 대중화에 대한 이론은 60년대에 와서 팝 아트 패션의 출현으로 그 결실을 보게 된다. 상류층을 대상으로 한 의상이 대중화되는 과정에서 60년대 경제호황으로 인한 젊은이들의 소비자층 형성과 미술양식에서의 팝아트의 출현은 자연스러운 시대적 조류로 나타났다. 이러한 상황은 팝 아트가 이 시대의 미술 양식에 혁신적일 뿐 아니라, 사회 전반에 팝 아트의 특성(소비 문화적, 대중 문화적, 재현적, 통속적, 기계적, 획일적)을 유행시키고, 대중에게 순수 예술과 복식에 참여 할 수 있는 기회를 부여했다고 볼 수 있다. 따라서 본 연구에서는 가장 혁명적이고도 대중적이라고 할 수 있는 팝 아트 이미지의 작품 제작과 분석을 통하여 현재 논의되고 있는 전시회나 패션쇼에서만 볼 수 있다는 다소 아방가르드 적인 의상 작품들의 대중화 방안에 대한 해결책을 모색하고자 하였다. 실제 의상 디자인 창작에 초점을 맞추었으며, 제작을 위해서 팝 아트에서 주요 소재로 삼았고 대중적 이미지의 심볼이라고도 할 수 있는 Coca Cola label을 표현 모티브로 삼아 개성적이고도 독창적인 의상 디자인을 한 후 분석하였다. 또한 독특한 의상 표현의 개발을 위하여 표현 기법으로는 현대 미술에서 새로운 재료와 여러 가지 재료를 화면에 도입시키는 표현 방법으로서 사용된 콜라주 기법을 사용하였다. 본 연구를 통하여 의상 창작에 있어 조형예술과 연결하여 대중적인 이미지를 도입함으로써 착용자가 예술에 대한 친근하고 익숙한 느낌을 갖게 하며, 예술과 상품 그 자체에 대한 상업적 홍보 목적으로도 사용할 수 있으며, 대중적인 이미지를 표현함에 있어 콜라주 기법은 염색 기법을 사용하지 않고서도 작가가 원하는 표현 효과를 낼 수 있다는 측면을 발견할 수 있었다. 즉 사용된 대중적 상표 이미지는 주인에서 흔히 볼 수 있는 현대 도시의 인공적 환경들로, 의상을 독특하고 개성 있게 표현할 수 있는 모티브의 역할을 하면서 또한 그 예가 무한하여 다양한 디자인 창출의 가능성을 갖고 있으며, 의상을 통해 예술과 대중을 융합시켰다는 예술의 대중화, 민주화라는 중요한 역할을 하였다. 전시회나 패션쇼에서 만 볼 수 있는 예술적 성격을 띠는 아방가르드 작품의 대중 확산 방법으로 제시될 수 있는 이상적인 방법으로는 예술성이 짙은 도저히 입을 수 없다고 생각되어지는 아방가르드한 의상을 일반 대중 브랜드들이 단순한 모방이 아닌 새로운 패러디 작업으로 일반화시켜 상업성을 띤 의상으로 재조정되어 여성들의 몸에 걸치게 하는 것이다. 이와 같은 순환으로써, 조형예술 작품은 의상 디자인 참작에 영향, 영감을 주면서 여러 번의 형태 변화를 거치는 패러디를 통해 각 계층의 누구나가 좋아하고 접할 수 있는 또 다른 창조를 맞아 대중의 손까지 갈 수 있는 것이다.

This study aims to find out the key factors that could influence on regional development strategy to use cultural resources. The methods employed are Meta-analysis with 61 case studies in order to draw related factors and Analytic Hierarchy Process with 68 experts in order to analyze the relative importance of important factors. The main findings are as follows: 26 critical factors are drawn from the case studies and they could be classified into four categories, named as 'the capacity building to excavate and utilize cultural resources which are having potential power', 'the establishment of institutional basis for making projects good progress', 'the boosting of internal capability of locals in the process of project', and 'the preparation of cultural governance and multidirectional networking strategies among persons concerned or stakeholder'. The analysis of relative importance of factors shows that among others, 'the capacity building to excavate and utilize cultural resources which are having potential power' is the most fundamental factors to achieve policy goals. There are few studies that have drawn factors from multi-case studies. In this respect, it is far from being complete but meaningful to a little more enhance the generalization of research findings.

FTA (fault tree analysis), an analytical method for system failure management, was employed in the management of faults in running PCR analysis. PCR is executed through several processes, in which the process of PCR machine operation was selected for the analysis by FTA. The reason for choosing the simplest process in the PCR analysis was to adopt it as a first trial to test a feasibility of the FTA approach. First, fault events-top event, intermediate event, basic events-were identified by survey on expert knowledge of PCR. Then those events were correlated deductively to build a fault tree in hierarchical structure. The fault tree was evaluated qualitatively and quantitatively, yielding minimal cut sets, structural importance, common cause vulnerability, simulation of probability of occurrence of top event, cut set importance, item importance and sensitivity. The top event was 'errors in the step of PCR machine operation in running PCR analysis'. The major intermediate events were 'failures in instrument' and 'errors in actions in experiment'. The basic events were four events, one event and one event based on human errors, instrument failure and energy source failure, respectively. Those events were combined with Boolean logic gates-AND or OR, constructing a fault tree. In the qualitative evaluation of the tree, the basic events-'errors in preparing the reaction mixture', 'errors in setting temperature and time of PCR machine', 'failure of electrical power during running PCR machine', 'errors in selecting adequate PCR machine'-proved the most critical in the occurrence of the fault of the top event. In the quantitative evaluation, the list of the critical events were not the same as that from the qualitative evaluation. It was because the probability value of PCR machine failure, not on the list above though, increased with used time, and the probability of the events of electricity failure and defective of PCR machine were given zero due to rare likelihood of the events in general. It was concluded that this feasibility study is worth being a means to introduce the novel technique, FTA, to the management of faults in running PCR analysis.
