한국데이터베이스진흥센터가 운영하는 데이터베이스 가이드 네트워크 DB가이드넷(Guide.net)이 지난 10월 22일 정보서비스 이용활성화 를 목표로 새롭게 오픈했다. DB가이드넷은 데이터베이스 산업에 종사하고 있는 실무자들에게 데이터베이스 관련 정보 및 지식을 제공하는 사이트로 지난해 10월 한국데이터베이스진흥센터에서 정보통신부가 추진하는 국책사업의 일환으로 서비스를 시작했다. 그동안 DB가이드넷 은 데이터베이스 관련 종사자들에게 데이터베이스 관련 기술자료, 전문가 칼럼, 시장동향, 사례연구, DB Q&A 및 산출물 등의 자료를 제공 했으며, 온라인 교육을 통해 연간 4억5,000만원 가량의 교육비 절감이라는 성과를 내기도 했다. 하지만 기존의 DB가이드넷은 사용자들의 적극적인 참여 기능 및 지식 공유 기능이 부족한 상태였기 때문에 1차 리뉴얼을 통해 여러 가지 기능을 보강하게 됐다.

본 연구는 1982년부터 2002년까지 우리나라 15개 산업부분의 패널자료를 이용하여 지식생산함수추정을 시도하였다. 해당 산업부문의 지식생산활동에서 서로 다른 산업부문간에 산호작용영향이 중요하다는 관점을 고려하여 Mark et al. (2005)이 제시한 DSUR(Dynamic Seemingly Unrelated Regression)추정량을 이용하여 관련된 지식생산함수의 모수를 추정하였다. 본 연구의 추정결과를 살펴보면, 우리나라 지식생산함수에서 연구원 규모가 지식생산에 기여하는 탄력성정도는 0.25이며, 기존 지식축적량이 기여하는 탄력성정도는 0.353으로 나타났다. 이러한 실증분석 결과는 우리나라의 경우에 기존 지식축적량이 새로운 지식생산에 기여하는 탄력성정도가 1보다 작음을 보여준다. 지식생산함수의 관하여 추정된 계수의 크기가 시사하는 바는 우리나라의 장기적 경제성장률은 제품 및 서비스생산함수에 관련된 탄력성과 인구성장증가율에 따라서 결정되기 때문에 정부의 직접적인 R&D정책개입보다는 지식관리 및 보급 그리고 공유체계정비라는 간접적 R&D정잭개입을 통하여 지속적인 경제성장전략을 추진해야한다는 주장을 뒷받침한다고 볼 수 있다.

Open science policies are spreading that disclose, share, and utilize research results produced through government public funds. As a policy to revitalize open science, interest in research support services that allow easy search, access, and reuse of results is increasing. To support services to provide researchers with various information, we propose a research resource knowledge graph model to meaningfully express the relationship between the scattered various outcome data. In this paper, it contributes to the improvement of the service of the national research data platform DataON by meaningfully connecting national R&D task information, researcher information, performance information, and research data information.

Social network services whose users increase rapidly is the online services that reflect social network. They are used for various purposes such as strategy of election, commercial advertisement and marketing, educational information sharing and exchange of medical knowledge and opinions. These services make users form social networks with other users who have common interests and expand their relationships by releasing their personal information and utilizing other users' social networks. However, the social network services based on open and sharing of information raise various security threats such as violation of privacy and phishing. In this paper, we propose a group key management scheme and protocols using key rings to protect communication of small groups in social network services.

Despite rapid changes in the structure of industry, manufacturing remains a key industry for economic progress, promotion of trade, increased employment, and the creation of new industries. Production technologies are essential for strengthening the competitiveness of small- and medium-sized manufacturing industries. However, it is very difficult to standardize and systematically propagate production technology from an experienced worker to an inexperienced worker because these technologies are generally improved by the skilled people in a workshop. In this study, we introduce a Web-based platform system consisting of a knowledge authoring tool, technology database, semantic database, and Web portal service for sharing production technologies for the exterior housing parts of mobile products. By investigating various cellular phone designs, reference form factors for three types of mobile phone housings were designed based on the standard features. In addition, several manufacturing technologies and considerable information such as reference mold designs and molding conditions optimized using CAE and recent R&D outputs are stored in this system.

Motivated by the open access movement, research institutions are building Institutional repositories for a nation-wide knowledge distribution infrastructure. IKIS (Institute Knowledge Inventory System) was proposed to integrate materials produced by government-sponsored 23 institutions of the economic, social and human fields, to contribute for policy-making in national agenda and to proffer services to a people. As IKIS project goes on. the project turns out to be slower than planned especially In terms of building up content and improving system functions. This study aims to investigate the methods for promoting the system in terms of management and system developments using multiple research methods such as surveys and interviews. Five issues including budgets and marketing are proposed for the management strategies, whereas three ones Including content and system performance improvements are suggested for the system development. The study results can be utilized as guidelines for managing university and school repositories as well as IKIS.

기존의 교차 도메인 추천은 일반적으로 서로 다른 도메인 데이터의 지식 결합이나 지식 공유를 바탕으로 진행된다. 이러한 방식들은 최소 한 개 이상의 도메인 데이터가 필요해서 모든 도메인의 피드백 데이터가 없는 실제 서비스 초기 상황에는 적합하지 않을 수 있다. 따라서 본 논문에서는 서비스 초반 모든 도메인의 피드백 데이터가 없고 콘텐츠 데이터만 존재하는 상황에서 교차 도메인 추천 시스템을 효과적으로 시작하기 위해 텍스트 임베딩, 클러스터링, 프로파일링 및 콘텐츠 기반 필터링을 활용한 추천 시스템 구성을 제안하고자 한다. 평가를 위해 여행지, 지역 축제, 공연을 포함하는 문화 관광 데이터와, 이에 대한 사용자 프로파일링 결과를 바탕으로 추천을 진행하였다. 그 결과, 콘텐츠 임베딩에 대한 유사도를 시각화하여 교차 도메인 아이템 간 유사성을 확인할 수 있었고, 사용자별 추천 결과를 통해 제안한 교차 도메인 추천 시스템이 유의미하게 동작함을 보였다.

Consumer health information is receiving more attention than ever before. This growing attention can be linked to the Internet and to people seeking more information on health topics. The purpose of this study is to suggest a design of the Knowledge management system for medical information services in a public library. As theoretical backgrounds, it discusses the issues regarding to the medical information services in a public library, knowledge management and knowledge management system. After that, 12 medical information sites are analyzed then the planning and the main menu of a medical information site for a public library are described. Finally, the model of the knowledge management system for a public library with 5 sub-systems are suggested: 1) knowledge creation system, 2) technology support system, 3) training system, 4) community service system, 5) knowledge sharing and network system. This system based on knowledge management will help provide the users high quality of medical information.

The purpose of this study is to find the beneficial plan for business success by the advantage of social media service in the business organization. There is few research for applying social media on a variety of fields in business organization although many companies are trying to find the way for its application. Hence, this study identifies the possibility for the utilization of social media services, and it also finds the plan for their effective application. The social relationship is created by increasing communications between users of social media service. The research model is established on the basis of the hypothesis that the social relationship affects knowledge share, pursuit of ego, social participation, amusement. To maximize the impact of results, the research was conducted on the basis of the target on two groups including the business men and non-business men who use social media services. As results of the research, the business men tend to appeal their impression based on sharing knowledge with anonymous people. Also, it is necessary to make a social participation to a management participation, and to utilize the social media in the organization by including amusement to its function. This research is expected to have significant implication to companies which wants to apply social media services in the future.
