This study is conducted to achieve following two purposes. First, this study investigates domestic conditions and problems of data broadcasting industry. Second, this study suggests the improving way of the legal and administrative systems in order to promote domestic data broadcasting industry. Survey was conducted with 16 companies and a few business men for gaining data of general condition and analyzing problems about domestic data broadcasting industry. The results are as follow: first, domestic industry was suffering from the lack of man power, finance, and the delay of data broadcasting service schedule. Second, respondents argued there was no the legal basis and the systematic regulation under the current digital broadcasting policy of government. To resolve those problems, this paper proposed the making laws preparing for the fusion service of communication and broadcasting, systematic assistance of government, the way of technology development and technical standardization, and the way of constructing infrastructure and cultivating man power.

The selection of the reasonable project delivery system (PDS) is crucial for a successful performance of a project, which means to achieve project objectives. Furthermore, the project performance has been tightly related to the selection of PDS appropriate to pertinent project characteristics. In this context, the ministry of finance and economy of Korea launched two new project delivery systems called "Best Value Contract (Design-Bid-Build)" and "Bridging Contract (Design-Build)" in October of 2007 by revising enforcement ordinances of "Act on Contracts to Which the State is a Party". For efficient operation of the new project delivery systems, this paper suggested a PDS selection model which supports decision making of the reasonable PDS for a pertinent project by assessing characteristics of the public construction projects, both quantitatively and qualitatively. In addition, a PDS performance evaluation model was proposed in order to get feedback on the result of the PDS selection and the operation for the succeeding project. The standard models suggested in this paper might be used as a tool to support the decision making of the public organizations.

Nowdays, with the explosive growth of the web information, web users Increase requests of systems which collect and analyze web pages that are relevant. The systems which were develop to solve the request were used clustering methods to improve the duality of information. Clustering is defining inter relationship of unordered data and grouping data systematically. The systems using clustering provide the grouped information to the users. So, they understand the information efficiently. We proposed a hybrid clustering method to cluster a large quantity of data efficiently. By that method, We generate initial clusters using COBWEB Algorithm and refine them using Ezioni Algorithm. This paper adds two ideas in prior hybrid clustering method to increment accuracy and efficiency of clusters. Firstly, we propose the clustering method considering weight of attributes of data. Second, we redefine evaluation functions which generate initial clusters to increase efficiency in clustering. Clustering method proposed in this paper processes a large quantity of data and diminish of dependancy on sequence of input of data. So the clusters are useful to make user profiles in high quality. Ultimately, we will show that the proposed clustering method outperforms the pervious clustering method in the aspect of precision and execution speed.

Women engineering education programs in the United States, Europe and Australia were analyzed. From 1970s, these countries focused on the low representation of women in engineering, and carried out extensive research and programs. Numerous studies identified the causes of low representation as low interests in mathematics and science during K-12 years, classroom environments which treat women differently (often referred as chilly climate), and the masculine culture in engineering. Comprehensive approaches were taken in the development of the programs: the programs utilized the schools and universities as well as various local institutes, and the programs were designed not only for female students from elementary to graduate levels, but also for parents, teachers, professors, and school administrators. In order to adopt these programs in Korea, the problems that Korean female engineering students are facing in the education environment must be investigated first. Then, unified efforts to change the educational system, environments and culture are needed by all in engineering fields, along with nation-wide policies and funding.

The popularity of the web based education has come the need for variety learning methods and for business to exploit the web not only for interoperability but also standardization. This way of standardization has come to researched for environments, contents and practical uses in ISO. The IEEE has special]y established five technical classes for LTSA which provide advanced e-learning environments. Feedback functions would not be supported and specified in standardization for Query Answer on LTSA. In this paper, we describe the query and answer model which we have developed on layer three of LTSA. We develop the redefined model for transforming data flow oriented into object or component based model. We have developed the Query Answer Metadata (QAM) based on Learning Object Metadata (LOM). We design and showed thing a prototyping implementation the Query Answer Learning Tool (QALT). We have used the QALT to address the problem of efficiency of web based education. We also used it to develop the related tools with quality and productivity.

The allotment rate for railway transportation keeps an yearly 6% in Korea. However, the railway logistics will cause the opposite result according to the continuous investment and logistics rationalization. The study on railway logistics as well as inter-Korean railway that might highly contribute to the development of railway logistics is not enough at all. The purpose of this paper is to study the revitalization strategy for inter-Korean railway by forecasting the demand and the scale of railway logistics depot. The revitalization strategies for inter-Korean railway through railway logistics depot are as followings. First, it is necessary to strengthen the partnership with coal user in the logistics depot. Second, it is encouraged to provide the financial assistance that are needed in the maintenance of the decrepit North Korea's track as well as the establishment of Donghae northern line that is from Gangneung to Jejin. Third, the railway cost on long/short transportation and large sized shipper is needed to apply in a flexible way. Fourth, it is necessary to obtain the railway traffic right by involving the foreign mining development. Fifth, it is encouraged to constantly find the small sized shipper like cement company.

This study examines internationalization index of higher education to draw implications for South Korea. To this end, this study first introduces the concept of internationalization of higher education, followed by the background of the development of internationalization index. Then examined are two internationalization index of higher education: one developed by American Council Education (ACE) and the other developed by OECD, which is known as IQRP (International Quality Review Process). ACE's international index of higher education is useful to governments when they assess the process of internationalization of universities. IQRP, on the other hand, is useful to universities and colleges when they evaluate their status of internationalization. Drawn implications are (1) it is important for universities to build a clear goal and implement appropriate strategies of internationalization, (2) policies on internationalization of higher education should concentrate on contents rather than forms, and (3) the efforts for internationalizing higher education should be made along with the efforts for improving the quality of education.

전세계적으로 집중호우, 홍수, 가뭄 등 기상이변이 빈번히 발생하고 있으며, 홍수기와 갈수기가 뚜렷해지고, 이에 따라 수자원 확보에 애로사항이 발생하고 있다. 이를 해결하기 위하여 정부는 "물의 재이용촉진 및 지원에 관한 법률"을 재정하여 효율적인 빗물 관리에 주력을 하고 있으나, 체계적인 빗물관리는 미흡한 실정이다. 즉 수자원을 효율적으로 보관하고 관리할 시스템 구축이 필요하다. 본 연구에서는 재배 작물에 대한 농업용수 확보를 위한 빗물저류조를 시공 및 모니터링을 하기 위하여 먼저 보은군 회인면 오동리의 기상 및 수문특성 조사를 실시하였고, 확률강우량을 산정하기 위해 보은기상관측소의 지속기간별 강우 자료를 수집하여 확률분포를 선정하고 매개변수를 산정하였다. 이에 따른 적합도 검정 결과 최적 확률분포형을 산정하였다. 분석한 결과를 통해 대상지역의 집수되는 면적에 내리는 유출량을 산정하였으며, 집수되는 유형은 지붕으로서 그에 대한 면적은 $120.0m^2$로 측정되었고, 지붕에 대한 유출계수로서 0.9의 값을 적용하였다. 지붕에서 집수되는 유출량의 값을 산정하였으며, 6월의 50년 빈도에서 부족한 9.4톤은 집수된 유출량으로 보충할 수 있는 것으로 판단된다. 따라서 50년 빈도의 10톤을 저류할 빗물은 저류조에서 30%의 여유율을 두어 13톤으로 저류조를 설계하는 것이 적정할 것으로 판단된다. 현재 빗물자원의 대부분은 바다로 유입되어 소모되거나, 하수로 유입되어 불필요한 고도처리공정이 진행되고, 하수처리장 용량에 과부하를 발생시키는 등 막대한 예산이 투입되고 있다. 갈수기시 농가에서 용수를 확보하기 위한 용수 운반장치 등 기반구축과 인력 부족으로 정상적인 용수공급의 어려움을 해결하기 위해서는 빗물자원을 용수로서 효율적으로 활용하기 위한 시스템의 구축이 필요할 것으로 사료된다.

There has been constant attempts for integration of public welfare delivery system which lead to integrated case management, then this become more significant issue regarding 'community care' recently in Korea. However, most of them was limited to fractional organization rearrangement or more use of private resources rather than realising user-centred approach. Therefore, in this research, we would like to do a couple of case studies in Britain which has rich experience of reforms for integrated approaches between health and social services and Troubled Family programme resembles the integrated case management in Korea by visiting a London Borough and a local council respectively. In conclusion, we found three conditions are required to establish successful integrated delivery system: elimination of institutional barriers relating to workforce, organization, and finance; shared objectives and partnership among the professional groups and agencies; and information sharing system with technical support regarding individual cases.

The result of this study was to measure the relative efficiency of 133 colleges in south korea and to investigate the differences in the results of college basic competency evaluation. As a result of the study showed that the average difference of efficiency according to the background variables was no significant according to the scale, location, and college evaluation. but differences in the type of establishment were found to vary significantly in S.E model. In addition, it was analyzed that the efficiency of the college with limited funding for the efficiency distribution is highly distributed, which indicates that it is necessary to continuously improve the existing university methods and to assess whether they are being managed effectively. Finally, the limitations of this study are that it used only quantitative data and that additional indicators could result in different outcomes from the results of this study.
