마이크로어레이 실험은 수 천에서 수 만개의 유전자 발현 결과를 동시에 측정할 수 있어 질병의 발현 형질 분류 등에 유용하게 이용되고 있다. 그러나 마이크로어레이 실험은 동일한 플랫폼의 실험이라 할지라도 환경 등에 따라 그 실험 결과에 차이가 나는 등 오차를 항상 포함하고 있다. 또한 마이크로어레이 실험은 아직 고가의 실험으로 분류되어 다수의 샘플에 대한 반복 실험 결과를 얻기 어려운 상황이다. 따라서 이종의 플랫폼, 데이터 포맷, 정규화 기법 등이 서로 다른 데이터를 효율적으로 통합하여 유용한 정보를 추출하는 새로운 방식의 개발이 필요하다. 본 논문은 이와 같은 문제를 해결하기 위한 기초 단계 연구 결과이다. 마이크로어레이 실험 데이터로부터 통계적 방법을 이용하여 유의(informative) 유전자를 추출하고 유전자 온톨로지(Gene Ontology : GO)와의 연계를 통하여 유전자 정보의 기능적 분류 결과를 사용자에게 제공하는 유전자 기능 분석 시스템의 설계 및 구현 방안을 보인다. 본 시스템의 실험방법에서는 3-Fold Filtering 기법을 통하여 발현 차가 큰 유전자를 추출하고, t-검정 기법에 의하여 이들 유전자를 순위화 하였으며, 이 중 상위 100개의 유전자를 유의 유전자로 추출하였다. 다음, 이 들 유의 유전자의 t-검정 값을 GO의 유전자 기능을 나타내는 해당 텀 (term)에 가중치로 부과하여 각 유전자들과 기능적으로 연관성이 높은 텀들을 추출한다. 또한 본 연구의 유효성을 검증하기 위하여 본 시스템에 의한 마이크로어레이 데이터 분석 결과를 전문가에 의한 유전자 기능 분석 결과와 비교한다.투명성 있는 서비스를 제공하고 높은 신뢰성과 안정성이 확보될 수 있도록 구성하고자 한다.

Nowadays the information exchange based on XML such as B2B electronic commerce is spreading. Therefore a systematic and stable management mechanism for storing the exchanged information is needed. For this goal there are many research activities for centering on relational databases the connection between XML application and databases. But when XML data which has hierarchical structure is stored as relational databases which are expressed as relational information, a set of 2-dimensional table, there is a limitation essentially. Accordingly the modeling methodology for storing such structured information in the form of object-relational databases is needed. In order to build good quality application systems, modeling is an important first step. In 1997, the OMG adopted the UML as its standard modeling language. Since industry has warmly embraced UML, its popularity should become more important in the future. So a design methodology based on UML is needed to develop efficient XML applications. In this paper, we propose a unified design methodology for XML applications based on object-relational database using UML. To reach these goals, first we propose a systematic three step methodology to extract UML, second we introduce a XML modeling methodology to design W3C XML schema using UML and third we propose a data modeling methodology for object-relational database schema to store exchanging XML data efficiently.

Korea has won 3 times in a row in the evaluation of e-government services in 2014. And the last year, the government-EA has been awarded the UN Public Service Award. Because of the development and execution of personalized integrated services based on the government-EA, Korea has won the two award from the UN. EA has been selected and proceeded as one of the 31 e-Government projects in early period, in 2005 the law which public sector must adopt the EA for efficient informatization had been enacted. Many public agencies in which actively utilized to derive such as internal and external performance through the EA. On the other hand, in the last 10 years, some public agencies have still been as recognized level of management in the EA. In this study, the main purpose is that to find out what is a major factor for successful use and result of EA, what is the EA success Model and how to examine it. To do that, this study will study the related prior research such as EA services, information systems success factors, performance measures, and develop the success model for EA and then examine the model. This study will contribute great implications in practical and theoretical in EA success model because this is the nation's first research that SERVQUAL model and the IS Success Model(DeLone & McLean 2003) has been combined and examined.

Financial industries have operated internal and external network with an unified system for continual business process of customers and other organizations in the past. The financial supervising authority requires more technical and managerial protecting policy to financial industries related to the exposure as danger of external attacks or information leakage. Financial industries performed network separation into internal business and external internet networks for protecting IT assets from malware infection accessing internet or hacking attacks and prohibiting leakage of customers' personal and financial information following financial supervising authority and redefine security policy to fit on network separated-condition. In this study, effectiveness for network separation policy was examined on malware inflow and verified that malware inflow in all routes can be blocked by the policy with analyzing operration data of a financial company, estimating network separation. Result of this study proves that malware infection route by portable storages was not completely blocked even on adapting network-separated condition. As a solution for this, efficient security policy would be suggested in this paper as controlling portable storages for maximizing effectiveness of network separation.

The National Education Information System (NEIS), one of ERP systems developed by Ministry of Education & Human Resources Development, has been utilized in primary and secondary schools. In this paper, we considered the NEIS should be used not only for educational administration affairs, but also for a lifelong management of National Human Resource. The current School Information Management System (SIMS) is unsatisfactory due to the insufficiency of actual field suitability and user's conveniency. For solving such problems, the system rebuilding or revision should be accompanied by. As a guideline of revision and supplement of the SIMS, we suggest an application useful in both schools and clinics by the integrating healthcare management information of people. For this, we propose a lifelong healthcare information management by integrating Student Health Records of the NEIS with Electronic Medical Records of doctors' offices. The healthcare information is designed and represented in XML. We applied different XSL style-sheets to XML documents in order to offer a view suitable for demands of schools and clinics. The healthcare information can be managed and utilized efficiently by using the view. We ascertained that the lifelong Healthcare Information Management System is an improvement to overcome the inefficiency of healthcare information management and the connection inadequacy between schools and medical institutions, and is desirable for a lifelong management of the National Human Resource.

The rural area of S. Korea has been excluded from the process of industrialization and urbanization, and is to be faced with a serious crisis in the context of recent globalization/localization with a rapid economic and political change. And hence it is required to give a active attention to community-based welfare for rural areas. The status of welfare of Koryung-gun as such a rural area adjacent to Daegu city is still low, even though recently it has been improved dramatically, and the welfare policy seems not to reflect the rapidly changing conditions of reality, though it has been institutionalized systematically. What is more, the number of dwellers who demand basic welfare has been increased, as welfare services seem not to delivered to them. In order to improve this totally low level of social welfare, major tasks should be pursued to formulate as basic principles an integral approach for community-based welfare and ultimately a restoration of rural community; to construct a mobilization system of diverse resources within community, to develop connections between welfare demanders and providers, and networks of institutes and facilities for community welfare; and to find out and to extend financial sources for welfare policies.

This paper attempts to evaluate the local economy and the local economic development policy in Goryeong County and to propose some policy alternatives for local economic development. Goryeong County has a locational advantage, which is not just geographically proximate to Daegu, a large metropolis, but also connected directly to the national highway networks. This region can also be regarded as a rural area, in a sense that the primary industry still plays a more important role for the local economy than the secondary industry and the tertiary industry. However, it is problematic that the local economic development strategies of Goryeong are universal rather than strategic and systematic. In order to design an effective regional economic development policy, the policy makers are necessary to deliberately consider regional specificity and geo-political and geo-economic situations around the region. In addition, it is important to say that policy makers, particularly in rural regions, need to break from the fantasy of high-tech industries. In this context, I propose some region-specific and context-specific policy ideas, including the promotion of the agro-food cluster and the build-up of the em-industrial complexes specialized in mechatronics and transportation equipment manufacturing.

As part of preparing for future earthquakes near three LNG receiving terminals located in coastal regions of Korea, acceleration monitoring systems were installed at four free field sites and on a pile foundation beneath a storage tank in a receiving terminal. Several equipments and accessories were devised to successfully install and operate the monitoring system at LNG receiving terminals. Synthetic earthquake-alarming software systems designed for decisionmaking, based on peak ground acceleration computed using the measured data, were developed for rapid response during earthquakes, not only in each local terminal area but also in the central control division. In addition, a framework software linking nationwide data on peak ground accelerations was included in the integrated earthquake alarming system in the central division, for various future applications. The earthquake alarming systems developed in this research for LNG receiving terminals, based on acceleration monitoring, represent a useful framework for industrial facilities located in coastal regions, where geotechnical conditions may show marked spatial variations.

This study analyzes the influence of the construction of a high-speed railroad on territorial organization in France. After development of a new transportation network, the French territorial organization has been largely modified. Many economic urban areas are modified by their position in the territorial hierarchy according to their condition of connection with the TGV network. At first, spatial convergence is the most important effect of the TGV network construction. Second, the development of a transportation network concentrated in the Paris area has influence as an intensified factor on metropolitan areas and as a weakening factor on middle- and small-sized cities. Thus, this system has risk in increasing territorial imbalance in France. Third, to implant an economic activity zone around new TGV stations, a new town or a new economic center starts to develop. This is going to grow into a second core outside of the old city center so that regional spatial organization is transformed from a mono-polarized(mono-centric) organization to a multi-polarized(polycentric) one. Lastly, the integration of the EU railroad system enhances the concentration of economic activity in European metropolitan areas as each metropolitan area tries to develop more competitive space for its rising position in the global urban hierarchical system.

Regional learning in social studies has an important educational meaning in that it is a tabloid edition of social studies and it also satisfies the regionalization of national curriculum. Social studies in Korea have mainly been led by the social study curriculum of elementary school. But the local textbook which was currently used in elementary school is structured in a negative meaning of regionalization rather than positive one. It is suggested in this study that the regional learning of social studies in middle school should be pursued by the co-work of teachers and students. For this purpose, the theoretical and practical processes to develop the local textbook are compared between two distinctive localities such as Sancheong and Seosan. At first, the relative ratio among the six strands is decided to develop several themes for regional learning, considering the landscape, region-related discourses and ecological environments in each region. Secondly, several themes are extracted to organize the contents of local textbook in each region. Lastly, examples of content-organization are suggested in each region. The processes above are just an example of content-organization, not a fixed one. The process, themes extracted, and the content-organization for each region may be changed according to the school location, local situation, and the quality of classroom.
