현대인들의 인터넷 사용률이 지속적으로 증가함에 따라 소비자들은 오프라인 매장에서 의류를 구매하기보다 인터넷 쇼핑을 통한 구매를 선호하게 되었다. 그러나 온라인 구매로 인해 정확한 스타일 확인 불가 및 확신할 수 없는 사이즈로 큰 불편함을 겪고 있다. 따라서 최근 가장 떠오르는 기술 중 하나인 AR을 실생활에 적용하여 사용자가 매장에 가지 않고 집에서도 편하게 자신의 스타일링을 확인할 수 있도록 하는 AR 피팅룸을 구현하여 솔루션을 제안하고자 한다. 본 프로젝트에서는 3D 표현을 위해 Kinect Xbox 카메라를 사용하여 사용자의 신체정보를 추출한 후 unity와의 연동을 통해 사용자에게 편리함을 제공할 수 있는 AR-fitting 시스템을 설계하였다. 선택한 옷을 가상으로 입어 볼 수 있는 쇼룸 형태의 서비스를 제공하며 제스처 인식을 통해 보다 편리한 의류 선택 및 사이즈 조절 등을 가능하게 하였다. 또한, 사용자의 입력 정보에 따른 사이즈 측정 결과를 제공함으로써 사용자의 의류 구매를 보다 효과적으로 만들어 줄 수 있을 것이다.

Nowadays, data-based scientific research is a trend, and the transmission of large amounts of data has a great influence on research productivity. To solve this problem, a separate network structure for transmitting large-scale scientific big data is required. ScienceDMZ is a network structure designed to transmit such scientific big data. In such a network configuration, it is essential to establish an access control list(ACL) for users and resources. In this paper, we describe the R&E Together project and the network structure implemented in the actual ScienceDMZ network structure, and define users and services to which access control policies are applied for safe data transmission and service provision. In addition, it presents a method for the network administrator to apply the access control policy to all network resources and users collectively, and through this, it was possible to achieve automation of the application of the access control policy.

To satisfy the requirements for QoS and acceptance ratio of the users using multimedia content service, it is required to control mechanism for QoS assurance and allocation of the stream server' resources based on CoS(Class of Service). To compare performance of the algorithm, we have classified the user by two classes (super class, base class) and control the acceptance ratio of user's requests by user's class information. We have experimented the test of network resources and test of processing time under server/client environment and agent environment. MA-URFA based on agent increases the acceptance ratio of super class and utilization ratio of network resources.

이 연구는 국제항법서비스(IGS)에서 진행 중인 실시간 IGS 산출물 서비스 구축을 위한 실시간 파일럿 프로젝트(Real-Time Pilot Project; RTPP)의 진행 현황의 파악을 위한 것이다. 본 동향조사에서는 RTPP의 구성요소 별 진행현황과 현재 기술 수준 및 해결해야 할 이슈 등에 대해 분석하였다. 조사결과 현재 4개의 분석센터의 실시간 산출물이 예비 서비스를 하고 있으며, 이를 활용한 연구도 활발히 진행되고 있는 현황이다. 하지만, 실시간 자료 전송을 위한 자료형식과 전송방식의 표준이 정해지지 않았고, 이온층과 대류층 정보의 경우도 아직 논의가 진행 중이다. IGS가 목표로 하는 실시간 서비스는 고정밀 위치결정, 우주환경, 자연재해 감시, 기상 및 기후 연구 등의 분야에 매우 활용도가 높은 서비스로 본 동향 조사를 통해 이를 활용하기 위한 관련 연구와 기술 개발에 있어 참고자료가 될 것으로 기대된다.

A reference linking service that is connection of each other different information resource need to setup the reference database and to match identifier. CrossRef, PubMed and Web Of Science etc. the many overseas agencies developed reference linking service, that they used the automatic tools of Inera eXstyles, Parity Computings Reference Extractor etc. and setup in base DOI and PMID etc. Domestic the various agencies of KISTI(Korea Institute Science and Technology of Information), KRF(Korea Research Foundation) etc are construction reference database. But each research communities adopts a various reference bibliography writing format. As, the data base construction which is collect is confronting is many to being difficult. In this paper, We developed the Citation Matcher System. This system is automatic parsing the reference string to metadata and matching DOI, PMID and KOI as Identifier. It is improved the effectiveness of reference database setup.

This study examines the way of making use of the science journals sharing with many users, who even do not work for the same institute. It may help to make the information as much as available with minimum financial burden to users. This is needed expecially when we recognize the fact that the amount of information supply is being increased rapidly while the financial environments around us are becoming aggravated.

In this paper, our goal is to examine the factors of user's satisfaction and information sharing in Social Network Services(SNS). Based on the theoretical framework like attachment theory and self-presentation theory, we develop and test a theoretical model, propose hypotheses and analyze the effects of emotional attachment and self-presentation on the satisfaction and information sharing of SNS users. For this research, questionnaire survey was conducted with literature study and the PLS(Partial Least Square) was used to analyze the measurement model and hypotheses testing. The PLS analysis results indicate that emotional attachment affects SNS users' satisfaction and information sharing. Further, information sharing is influenced by self-presentation of SNS users. Practical implications of these findings and future research implications are also discussed.

In Korea, there is a high demand for the operation of differentiated programs in basic research considering the characteristics of academic fields. The results of this study shows that the higher the level of research competence, the higher the quality of research outputs. The results also tell us that the quality level of the research outputs is different according to the field of study. Based on the results, we propose a method to differentiate the selection rate of each discipline in the system that operates the individual basic research projects by the level of research capacity.

The purpose of this study is to review and analyze the overlapping functions and activities of the nationwide scientific and technical information network system This study is helpful for users to gather information and for librarians and nations to reduce wastage of budgets through discarding the duplicated expenses of performing activities of the network systems. The research targets are KISTI and KERIS, which are functioning as the information network systems in the fields of science and technology. The research methods are literary reviews for theory background and analysis of their activities from internet homepages. As a result of the research, it is found and confirmed that there are some overlapping and duplicating functions and activities in the network systems.

본 연구에서는 CDMA 기술에 기반한 IMT2000 시스템을 연구중인 cdmaOne 3세대 CDMA MAC을 이용한 무선 패킷 음성 서비스 프로토콜(WPVCP : Wireless Packet Voice Convergence Protocol)을 설계하고 성능을 평가하였다. 설계한 WPVCP 프로토콜은 회선형 서비스 중심인 이동 통신의 음성 서비스 구조를 패킷형 서비스 개념에서 지원하도록 하였으며, 이를 통하여 제한된 무선자원의 활용을 극대화하였다. 아울러, 묵음 구간으로 인한 기존 회선형 방안의 음성 서비스와 제안한 패킷형 음성 서비스를 비교 분석한 결과 제안한 방안의 성능이 end-to-end 의 음성 품질을 지원하는 구조에서 최대 250% ~280% 수준의 가입자 증대효과를 나타내는 것으로 확인하였다.
