최근 클라우드 컴퓨팅 기술의 발전은 기존에 어려웠던 응용연구 분야의 실험 환경 구축을 용이하게 함으로써 새로운 협업연구 패러다임을 가져오고 있다. 본 논문에서는 고성능 연구망 기반의 협업연구 환경을 구축하기 위해 필요한 데이터 공유 및 전송에 관한 서비스 제공 방안을 제안한다. 이러한 서비스 모델은 연구망의 특성을 반영하고, 접근 패턴이 다른 사용자들을 동시에 수용할 수 있도록 구성된다. 이를 토대로, 최근 오픈소스 소프트웨어로 활발히 이용되는 서비스 구성 요소들을 분류 및 선택하여 실험 테스트베드를 구성하고, 활용 시나리오별 데이터 전송 실험을 수행함으로써 제안 서비스의 활용 가능성을 확인하였다.

In this paper, we suggest the GUI Management Tool, named K-Manager, for management and service of science and technology information that stored in distributed retrieval databases. Generally, it must be adapted retrieval database system for web based S&T contents service. But, It is inconvenient contents manager or the system administrator controls information easily, because it does not support the S&T information management process like TOAD, which can use for the relation database, in information retrieval database system. Using K-Manager, content manager can process the S&T content and system manager can manage the databases easily. The proposed tool active controls information effectively which is stored in the distributed retrieval database which guarantee the safety management of the contents stored in database and operate retrieval with efficient performances. Our tool consists of two sub systems, one is content manager, the other is database manager for YESKISTI based on KRISTAL-IRMS.

Information Technology Service Management (ITSM) System has been adopted and operated by many governments and public institutions to intensify their global competitiveness. Recently these organizations are facing many problems because of the increased demands and complexity of Information Technology (IT) service. Especially, difficulty with ITSM gets bigger and bigger because of increasing IT outsourcing. An expectation regarding ITSM is grown up when facing to solve problems. Therefore, this study suggests effective alternatives about ITSM organization structure for public sectors. The ITSM organization structures changes from traditional structures based on functions to new structures based on its goal, customer, and its process. In other words, ITSM organizational structure can be composed of Service Strategy directorate, Service Design directorate, Service Transition directorate, Service Operation directorate, and Service Improvement directorate. To ensure the effectiveness and the professionalism of ITSM in an organization, this paper specifies the roles of participants and the responsibilities for each unit. The proposed ITSM organization structures will be useful for public sectors.

Information on and knowledge of science and technology in the knowledge-based society can be a valuable natural resource and a source of competitive advantage for a country. In addition, in conducting research and developing technologies, information on and knowledge of science and technology is becoming increasingly important and customer's needs are becoming more diverse. This study thus aims to propose appropriate strategies for effectively coping with needs of those customers who use such knowledge and information by actively reflecting a broad diversity of customer' needs and comments. Using such strategies, we developed a standardized and integrated helpdesk system to enhance the quality of customer support and other services, customer monitoring service, and customer satisfaction.

Web Map Service on mobile environment, provided with cost effective mobile GIS contents and user preferred POIs(Points of interests), is strongly required at this moment when mobile and portable Internet is rapidly spreaded on mobile user community as information technology and mobile HW are evolved in its speed, bandwidth and features. As the mobile and portable Internet becomes popular in mobile services, LBS(Location Based Service) is positioned on a mobile client as one of the best information infra services. Recently mobile GIS (Geographic Information System) comes in service to support LBS, but it is constrained and limited on its system configuration and its presentation methodology of a map, and also it depends on its run time environment. In this paper, we made an effort to design and implement a GIS computing platform with server based thin client for mobile WMS(Web Map Service). For its cost effective Platform which could be easily building up POIs and GIS contents, we're not using commercial GIS solution but NGII's (National Geographic Information Institute's) DXF numerical map, and representing the maps, GIS contents and POIs by SVG(Scalable Vector Graphics) recommended by OGC(OpenGis Consortium). We're also adapting de facto standard of XML web service technology such as WSDL, SOAP to provide real time mobile GIS service on PDA as well as mobile terminal by applying a GPS receiver for a user's location information on mobile environment.

위성통신의 이용과 기술발전 추세를 살펴보면, 1950/60년대에는 미국, 프랑스 소련 및 영국을 중심으로 국방 및 과학기술측면에서 위성을 보유운용 하였으나, 1970/80년대에는 브라질, 호주, 중국, 인도 및 인도네시아와 같이 국토면적이 넓거나 섬이 많은 국가에서 위성의 특징을 활용하였다. 그리고 1990년대 이후에는 새로운 정보통신 및 방송서비스 영역을 확장하기 위해 개발도상국에 이르기까지 위성의 이용은 상당히 증대될 것으로 기대된다. 또한 선진각국들은 최근 급속한 발전을 이룩한 디지틀 신호처리기술, 부품 및 소자기술 등을 이용하여 다기능 및 고효율성을 갖는 위성시스팀 개발을 진행해오고 있다.

오늘날 도메인 네임 시스템(DNS) 서비스는 단순히 IP 주소를 .com, .net 등의 도메인으로 변환해주는 기능을 넘어 컨텐츠 가속(CDN) 서비스, 고가용성(HA) 서비스, 분산 서비스 거부공격(DDoS) 방어 서비스, 통신 구간 암호화 서비스로서 그 용도를 넓혀가고 있다. 이용자들은 이러한 업체가 외부 기관에 정보를 넘기지 않고, 모든 통신 구간은 서비스 업체도 그 내용을 들여다보지 못할 정도로 철저히 암호화한다는 도덕적인 영업과 운영을 할 것으로 기대하지만, 실제 사례를 살펴보면 그렇지 못하다는 점이 드러난다. 본 논문에서는 2021년 기준으로 최소 7년간 이어져온 것으로 추정되는 유명 DNS 서비스 업체의 보안접속 악용 사례를 중심으로 이러한 악용이 어떻게 이루어지고 이것에 대응하기 위해 사용할 수 있는 표준화 기술은 이 문제에 효용성이 있는지를 DNS 업체와 동일한 실제 환경 구성을 통해 검증하였다.

Hyperlink is a directly followable reference within a hypertext document. With a help of it, we can get information conveniently and save the cost for obtaining content in internet. KISTI(Korea Institute of Science and Technology Information) applied the hyperlink to GTB(Global Trends Brief service). GTB gatehers quickly the latest information of science, technology and market which is necessary to policy maker, businessman and researcher. This report explained the method how applied hyperlink to GTB and showed the examples.
