This study is about the factors required to be considered in the aspects of policy and operation before introducing the real-time reference service and about the way to use the real-time reference service effectively, The real-time reference service should not be accepted and applied just based on the case of advanced nations without deciding how to apply and use through enough advanced investigation and example analysis. Working out in service policies, selecting appropriate programs. securing service manpower, devising privacy policies, groping the ways of cooperation between libraries, and operating the adequate evaluation system are the factors which should be considered in the policy aspect. Preparation of proper ways of application. operation time, and promotion are the factors which should be considered and reviewed in the operative aspect.

This paper outlines the concept of real time reference service(RTRS). Then, it analyzes real time reference service in the 13 libraries for effective reference service. As a result, the most used software was AOL instant Messenger, followed by Conference Room from WebMaster, and LivePerson. Hours of service was generally same as reference desk hours. The users were Students. faculty, staff, and alumni, This study also demonstrated how the RTRS in LC works. The results showed that real time reference was able to response to patrons quickly for reference questions with interactive method.

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.

This study examines basic concepts and characteristics of QuestionPoint, the typical model of Collaborative Digital Reference Service and Global Reference Network, and analyzes the case of Question포인트 service at Korea Institute of Science and Technology Information where the service is initiated first time in Korea by developing Korean interface. 114 reference questions were analyzed, and questionnaires were sent to 63 service users to find out their overall attitudes and degree of satisfaction. Some suggestions were made by discussing the necessity of the enhancement of CDRS and mutual cooperation among Korean libraries.

본 논문에서는 최근 인터넷 상에서 표준 공통 포맷으로 대두되고 있는 XML을 이용하여 웹 기반 원격 교육 시스템에서 강의 내용에 참조도리 참고문헌 지원 시스템을 설계하고 구현하였다. Three-tier 환경에서 구현한 이 시스템은 middle-tier인 웹 서버에서 데이터베이스에 저장된 참고문헌을 XML 데이터로 변환하여 효과적으로 처리함으로써 서버의 부하를 감소시키며 이것은 성능 향상으로 이어져 학습자에게 더 나은 속도로 원격 교육의 참고문헌 정보서비스를 제공할 수 있다. 또한 동적으로 서버와 상호작용 가능하도록 학습자가 c마고 문헌의 유익함 정도를 매긴 등급 점수 계산에 직접 참여시켜 그 결과를 볼 수 있도록 하여 학습 의욕을 더욱 고취시킬 수 있다. 앞으로 웹기반 원격교육의 참고문헌 지원 시스템은 세계 각 대학이나 연구소에 분산되어 있는 여러 데이터 소스로부터 필요한 정보만을 실시간으로 추출하여 수집, 통합, 통계 처리할 수 있도록 확장될 수 있을 것이다.

EPLA 패킷 스케줄링 알고리즘은 IEEE 802.22 WRAN 시스템의 실시간 트래픽 전송 지원을 위한 패킷 스케줄링 알고리즘으로 참고문헌[4]으로 제안되었다. 패킷 기반 무선 전송 시스템에서 실시간 트래픽의 경우 짧은 데이터 유효 시간을 가지며, 만약 데이터 유효 시간이 초과할 경우 실시간 트래픽 데이터로써의 가치를 상실하기 때문에 시스템에서는 해당패킷을 전송하지 않고 제거해 버린다. 그러므로 실시간 트래픽의 중요한 서비스 품질(QoS) 인자인 요구된 패킷 손실율을 보장하기 위해서는 실시간 트래픽의 데이터 유효 시간을 고려하여 자원을 할당하여야 한다. 기존의 패킷 스케쥴링 알고리즘들은 많은 경우 큐의 맨 앞에 위치한 패킷의 지연 시간을 고려하지만 EPLA는 패킷이 저장되는 큐 내의 다음 프레임에서 제거 될 것으로 예상되는패킷의 손실양을 고려하여 자인을 할당함으로 기존의 실시간 패킷 스케줄링 알고리즘에 비해 훨씬 좋은 성능을 보인다. 하지만 EPLA는 예상되는 패킷 손실양을 계간하기 위해서 모든 사용자의 큐에 저장된 패킷들을 확인해야하므로 높은 복잡도를 가지는 문제점이 있다. 본 논문에서는 각 사용자로부터 피드백 받은 부채널의 상태 정보를 기반으로 사용자 큐를 확인하여 횟수를 제한함으로써 패킷 손실을 성능의 손실 없이 복잡도를 줄이는 간단한 방법을 제안하고, 실시간 트래픽인 음성 트래픽과 비디오 트래픽에 대한 시뮬레이션 결과를 통해 이를 확인한다.

The social curation service that selectively provides information generated by individuals or groups with the same interests can have a synergistic effect when combined with the recently used SNS-based chatting function. If these kinds of chatting-based curation technologies are applied to the Internet shopping malls, particularly, buyers can obtain more reliable information in real time basis, and sellers can provide them with more differentiated and rich information in a continuous manner. This research suggests a chatting-based commerce platform that provides the social curation service based on chats among sellers, existing buyers, and potential buyers. The proposed commerce platform can organize a chat channel for each store and product not only to immediately respond to new and existing customer inquiries about stores, brands, and detailed products, but also to continuously activate differentiated sales strategies to customers subscribed to the channel. In particular, MongoDB is used to permanently save and archive the information and chatting history of each channel, so that the buyer can search and refer to them recorded in the corresponding channel at any time.

A log file in web server stores various information of web server. The web server information is good reference information to improve web service quality. Also if web server occurs any fault, log file information is important information to find out occurred error. Currently, many of web server manager that they have wire have disadvantages in mobility. In order to solve above problem, this paper represent web server manager based mobile. Incase web server manager based mobile, it can immediately know recent log information accessing real-rime as also anytime, anywhere

This research dealt with the methodological procedures of ubiquitous sensor networks, applying to urban ground facilities. Recently Korean government established a guide, "u-City IT Infra guide v1.0" when promoting u-City implement projects. This guide conceptually included general processes about u-City mainframe in overall, but its guidance could not lead the detailed procedures and methods for specific ground facility. Therefore, this research proposed the details of the procedure for the intelligence of facilities after reviewing the existing procedures for ubiquitous city. Newly proposed procedure for the intelligence of facilities was consisted of selection of facility and sensors for intelligence, setting a level for intelligence, and suggestion of service model for the selected facility.

Demands for tangible contents using VR/AR technologies are much bigger as contactless services such as sports, physical activity, and fitness are expanded after COVID-19. A variety of technologies such as an offer and analysis of tangible data through a sensor technology, users' physical movement sensing through a motion recognition sensor, a real-time measurement of a physical skeleton point a multiple access to a real-time video, and AI training are being utilized as main technologies. This case study utilized motion recognition technologies as the study on tangible contents necessary for indoor-based physical education, sports, and fitness in the contactless environment and suggested cases to develop the physical measurement contents by design approach for the measurement assessment necessary for the development in tangible contents. The research established lists of the measurement assessment based on professionals' consultations within the measurement assessment function through the test to plan tangible contents and developed tangible contents by reflecting them as assessment measurement elements of tangible contents. The research can be utilized as the design approach of industrial companies which intend to develop tangible contents as well as reference cases of the research on contactless tangible contents for the sports and physical education.
