In this paper, we present a framework which enables users to interact naturally with hand gestures on a digital table. In general tabletop applications, one gesture is mapped to one function or command. Therefore, users should know these relations, and make predefined gestures as input. In contrast, users can make input gesture without cognitive load in our system. Instead of burdening users, the system possesses knowledge about gesture interaction, and infers proactively users' gestures and intentions. When users make a gesture on the digital surface, the system begins to analyze the gestures and designs the response according to users' intention.

Nowadays research collaboration between the business, academic and governmental community is high on the policy agenda in all over the world, especially with regard to science-based technological innovation. The aim of this paper is to explore some of the changing spatial patterns of research collaboration by carrying out bibliometric analysis of co-authorship publications in major international and scientific journals that are jointly realized by Korean scientists and researchers in the seven science-based technologies for the period 2002~2012. Using the co-authored papers as an indicator of research collaboration with the institutional address of each co-authoring researcher and the geographic location of their affiliation, this paper describes some trends and patterns of domestic and international research collaborations. Identifying a rapid increase in the volume of co-authored papers and the trend towards multiple authorships over the last decade, the paper finds collaborative scientific research to be geographically dispersed at the different spatial scales. Despite the rising geographic dispersion of research collaboration within the nation, this paper finds that there were empirical evidences for the presence of localized knowledge production processes at regional level, and biased knowledge flows towards core areas with advanced research resources.

Knowledge network is considered to be an important factor in securing regional economic performance and competitiveness. In addition, research institutes that are capable of absorbing knowledge tend to form a global knowledge network regardless of geographical factors, and those that are not, are heavily influenced by regional factors. In this study, we examined how much influence of geographical factors of knowledge network is influenced by lower knowledge absorptive capacity in Korea. As a result, it was shown that the higher institutes of knowledge absorption, the more international collaborative research is being carried out. In other words, a region where science and technology has developed means that regional factors are no longer important factors. The results of this study correspond with the discussion of the preceding theories. In addition, it is worthy of study in that the precedent study was carried out in the case study in Korea.

월드와이드웹(World Wide Web)의 발전과 더불어 지리정보시스템(GIS)은 웹사이트를 통한 공간 데이터의 접근에 대해 많은 관심을 가지게 되었다. 이러한 진보는 지리정보 산업이 단순한 공간자료 전달이 아닌 지식과 정보를 전달하는 새로운 단계로 성장한 것을 의미하며, 또한 공공의 목적뿐만 아니라 민간분야의 사업에 활용되어 부가가치를 높이는 계기가 되었다. 웹을 이용한 지리정보 유통에 대한 관심의 증가로 등장한 geoportal은 유럽의 여러 선진국과 미국 등에서 지역적 국가적 세계적인 범위의 공간정보 관리를 위하여 연구되고 있다. 본 연구는 유럽과 미국 등 기존의 통합유통체계에 대한 사례조사를 통해 우리의 geoportal 아키텍처를 제시하였다. 아키텍처는 Web portal, Web service, Data management를 구성요소로 하여 상호운용을 위한 미들웨어에 대해 논의한다.

문자 정보 및 X-Ray, MRI, CT등과 같은 의료영상 정보를 취급하는 의료정보 시스템에서의 유사객체 검색을 지원하는 협력 의료정보 시스템의 설계에 대하여 논한다. 이를 위해 객체간 의미적 관련성을 기반으로 한 유사도 자동 추출 방식 및 지식베이스 구성 방식을 제안하고 이를 활용한 유사객체 검색에 대하여 논한다. 특히 의료영상을 객체 값으로 갖는 경우 객체간 유사도는 영상처리의 특징추출 방식에 의해 추출된 영상내에 출현하는 공간 객체의 위치, 면적, 둘레, 공간 객체간의 위상 관계 등의 공간 속성을 이용한다. 여기서 공간적 위치에 근거한 유사도는 공간 위치를 대표하는 Hilbert값의 분포와 빈도를 토대로 계산한다.

Asbestos is a toxic material that can lead to lung cancer and other diseases. There is no information regarding areas in Korea that contain asbestos in nature; consequently we need to manage such areas with care. The purpose of this study was to construct a local graded map of asbestos exposure risk based on the natural occurrence of asbestos in rocks. We first developed a means of evaluating the asbestos exposure risk and produced thematic maps based on a field survey. In addition, we constructed a knowledge base for asbestos through analysis, representation and processes about asbestos data and prepare for the development of an evaluation model for asbestos exposure risk. The spatial analysis of asbestos exposure risk is based on a weighted-overlay analysis using expert opinion and the literature, and a fuzzy-overlay analysis using the uncertainty in the data. The map of asbestos exposure risk, compiled according to the weighted and fuzzy operations, is expected to be used to ensure safety and to reduce the risk of exposure to asbestos.

The purpose of this study is to propose a method to construct the information space of library with the resilient space and community base to cope with social changes in response to various contents of library functions. As an institution that provides the places and contents necessary for education and research, it aims to expand and change from the collection center to the user center, from the specific user center to the library that shares resources with the community, And to find ways to contribute to the revitalization of education. A library plan for communities that can increase the value of local libraries and expand user-centered space utilization is as follows; First, in terms of communities in space and programs, the program will be supplemented through the activation of cultural, entertainment, and collaborative programs and the creation of communities. Second, in terms of smart support for operational and environmental issues, the establishment of information technology and smart management operating system to expand the research productivity by efficiently utilizing mutually available data with the local community.

Knowledge management is a core factor to achieve competitive advantage and improve the business performance. New information technology is also a core factor enabling the innovation of knowledge management. Semantic Web of which the goal is to realize machine-processable Web can't help affecting the knowledge management. Therefore, we empirically analyze the relationship between user's dissatisfaction and barriers or limitations of knowledge management and present methods allowing Semantic Web to overcome the limitations and to support knowledge management processes. Based on a questionnaire survey of 222 respondents, we found that the limitations of system qualities such as user inconvenience of knowledge management systems, search and integration limitations, and the limitations of knowledge qualities such as inappropriateness and untrust significantly affected the user dissatisfaction of knowledge management systems. Finally, we suggest a conceptual model of knowledge management systems of which components are resources, metadata, ontologies, and user & query layers.

In most countries, public libraries have played a role as a hub of knowledge and information, complex culture of local communities, and a third place for meeting and communication. And recent public libraries are focusing on enhancing their core competencies and expanding services using digital technologies to meet the era of digital transformation and the 4th industrial revolution. However, after the COVID-19 pandemic occurred, all public libraries are repeatedly closed, reopened, and partially closed, and all resources are devoted to providing non-contact, digital and online alternative services, and are expected to continue in the future. As a result, future public libraries are bound to face a trilemma in which digital expandability, complex cultural space, and importance as a place of knowledge and information service are conflicting. This study discoursed on the public library trilemma in the post-COVID-19 era and suggested ways to overcome it. The orientation of the future public library is the fusion and harmony of multiplicity and multipurpose, place and space, knowledge & information and complex culture, face-to-face service and remote service. The main body of a public library is not the finger (digital and non-contact), but the moon (knowledge information center).
