인터넷의 발달로 디지털콘텐츠의 생성과 활용이 급격히 증가하면서 디지털콘텐츠에 대한 서비스 방식이 URL 방식에서 URN 방식으로 변화하고 있다. 한국과학기술정보연구원의 KOI나 한국전산원의 UCI가 그 예라고 할 수 있다. 그러나 식별체계 간의 등록$\cdot$변환서비스가 호환되지 않기 때문에 식별체계를 활용하여 디지털콘텐츠를 서비스하기 위해서는 커널메타데이터를 각각 등록하여야 하며, 디지털콘텐츠 변환서비스도 서로 연계가 이루어 지지 않기 때문에 개별적으로 서비스 되고 있다. 디지털콘텐츠를 보다 효율적으로 생성$\cdot$활용하기 위하여 식별체계간의 등록$\cdot$변환서비스 연계가 가능한 식별체계 간 연계시스템 구축 방안을 제시하고자 한다.

For scalable multicast transport, one of the promising approaches is to employ a control tree known as acknowledgement (ACK) tree which can be used to convey information on reliability and session status from receivers to a root sender. The existing tree configuration has focused on a 'bottom-up' scheme in which ACK trees grow from leaf receivers toward a root sender. This paper proposes an alternative 'top-down' configuration where an ACK tree begins at the root sender and gradually expands by including non-tree nodes into the tree in a stepwise manner. The proposed scheme is simple and practical to implement along with multicast transport protocols. It is also employed as a tree configuration in the Enhanced Communications Transport Protocol, which has been standardized in the ITU-T and ISO/IEC JTC1. From experimental simulations, we see that the top-down scheme provides advantages over the existing bottom-up one in terms of the number of control messages required for tree configuration and the number of tree levels.

In this paper, we propose a direction for improving 'Geospatial information open platform' service to support the converged and integrated geospatial information. Since there can be a number of issues relating to the support for geospatial information convergence industry, two qualitative surveys were performed to collect opinions comprehensively and specifically. The responses from 165 experts from 5 areas that use geospatial information were used, and the requirements of demanders were divided into the aspect of policy, aspect of data development and distribution, and aspect of data utilization support in order to effectively analyze the survey results. As a result, a total of 26 major issues were derived and it was deemed that it is necessary to find a way to expand the role of 'Geospatial information open platform' from "Open-API Oriented Passive Spatial Information Open Platform" to "Platform that Comprehensively Provides Active Convergence Support Information" order to resolve the issues derived.

SME's(Small and Medium-sized Enterprises) have limited resources to build information systems on their own. They do not have effective information systems and not utilize e-business technology enough. The government thus have provided various supports for SME's IT developments. However, those supports do not seem so effective that SME's can operate appropriate information systems and do e-business well. The objective of this study is to develop conceptual policies for the government. We suggest an integrated government support which consists of three core stratigies: one-stop service center, outsourcing of public service, and triggering strategy. In order for the government support to be effective, the government should serve SME's needs continuously and professionally.

정보기술을 통한 건설산업의 관리 체계화와 생산성 증대 및 경쟁력 제고를 위해서는 우선적으로 건설업체에서 구축 $\cdot$ 활용하고 있는 정보시스템의 활용특성에 대한 체계적인 정리가 필요하다. 특히, 건설의사결정측면에서 건설데이터를 활용한 고급분석기술인 의시결정지원기술에 대한 전략적이며 체계적인 적용모델을 적립할 필요성이 대두되고 있다. 즉, 건설업체의 정보시스템에 대한 구축 수준을 파악하고 건설의사결정지원과 관련된 문제점을 도출해 낼 수 있는 합리적인 분석틀을 통해 건설정보시스템의 전략적 활용 방안에 대한 기초적인 연구가 필요하다. 이를 위하여 기존 연구들을 바탕으로 푹적된 데이터의 부가가치를 높일 수 있는 대안으로서 의사결정을 지원하기 위한 정보시스템 활용특성 모델을 제안하고 사례연구를 통하여 그 타당성을 검증하였다. 본 연구를 통하여 건설업계의 의사결정지원기술에 대한 인식제고와 건설조직에서 활용하고 있는 정보시스템의 적극적 활용의 대안의 기초를 마련하고자 한다.

The market for commercial open source software (OSS) has been rapidly growing with the proliferation of OSS. One way to commercialize OSS is the support model, which has been adopted by leading OSS firms such as Red Hat and JBoss. Despite the growing interest in OSS commercialization, little research has provided OSS support providers with a pricing guideline. In this paper, we examine the optimal pricing strategies for OSS support providers. Our benchmark is a monopoly case in which we investigate a startup software vendor's incentive to choose the OSS support regime over the proprietary one. Then we extend the model to a duopoly case in which OSS under the support regime competes against proprietary software. We characterize the conditions under which the OSS support model is viable under competition. We believe that our results offer insights to the OSS vendors who consider commercializing their OSS with a support model.

This study is to test moderating effects of North Korean Refugees' coping styles in the causal relation between social support and psychological wellbeing and suggest policy implications for helping social adjustment of North Korean Refugees. For this study, 100 North Korean Refugees were sampled and surveyed. The analytical result of this study showed that the degree of psychological wellbeing was highest among the refugees of the entire families migration. Also, this study showed that the causal relationship between social support and psychological wellbeing was not significant, and moderating effects of emotional support and appraisal support were significant, while moderating effects of material support and informative support were not significant. In this study, we suggested some policy implications basing on this analytical results.

This paper discusses the characteristics and effects of dielectric inner-supports on discone antenna for broadband RF test chamber, and the verification has been performed by simulation. Several design parameters such as the thickness of the gap support, the position of the side support, and the thickness of the side support has been analyzed. The thickness of the gap support affected the reflection coefficient. An effect of the offset of the side support from the center was slight below 3 GHz and significant above 3 GHz. The thickness of the side support did not affect the reflection coefficient or the gain much. The performance of the fabricated discone antenna was in good agreement with the simulated results. This investigation of a dielectric support effects could be used to design a commercial discone antenna for broadband RF test chamber, focusing on electrical performance and mechanical stability.

The purpose of this study was to find the effects and problems in the support projects in multicultural family support centers and to present suggestions for its improvement. For this purpose, 10 specialists in 3 multicultural family support centers in Daegu, who organize and operate projects for female immigrants and their families, were interviewed via focus groups and then interviewed in-depth. The major findings were as follows: 1) the effect of the support projects was an increase in participation and concern of female immigrants and their families; 2)problems of the support projects included lack of flexibility of the projects, and overlap of projects among centers. 3)The results of the study suggest improved operation by extending the support networks to other support centers and facilities within the community, increasing the individualized programs based on their specialties, and promoting integrated projects (such as combining language courses and cultural programs, family-support programs and cultural events). Further studies will be extend to find out model cases from support projects of several centers, expand them to other centers, and verify its effects on operating projects.
