As modern science and technology and warfare become to be advanced and precise, the weapon systems becomes more complex based on state-of-the-art technology. Therefore, firms in the defense industry continue to accelerate research and development for up-to-date weapon systems with high complexity which urge the firms to collaborate with the external organizations to obtain the knowledge required and eventually to reduce costs and risk. This study tries an empirical study about the effect of collaboration on the innovation performances from the network analysis perspective. By surveying collaboration relationships among 530 firms in the Korean defense industry, we analyzed the alliance network of the defense industry. Network centrality including degree, closeness, and betweenness centralities is investigated and then the relationship among the network centrality property, internal R&D capabilities and innovation is analysed. The results show that firms with high internal R&D capabilities place the firm at center of the network. On the other hand, except for the firms with highly connected centrality, no relationship was found between the internal R&D capabilities and its performance and in turn. these capabilities had both direct and indirect effects on innovation performances through mediated collaboration among firms. This study implied that Korean firms with a high internal R&D capabilities in the defense industry which utilize knowledge, information and resources within the network more frequently show more innovative performance. This result claims the policy makers to participate more firms in fostering open innovation for the defense industry.

Recently, self-adaptive system researches have been done to solve the problems occurred in the dynamic environment. Designing requirement in the self-adaptive system is necessary to recognize and solve the problem for the system, and if a developer reuses existing adaptation strategy to design the requirement, the designing time and cost would be reduced. Therefore, this paper proposes the system which extracts reusable adaptation strategy from the existing self-adaptive system. For the proposal, this paper conceptualizes the self-adaptation elements, defines the adaptation strategy ontology and target system ontology, and presents the process of extracting reusable strategy. This paper also implements proposed system and evaluates the reuse rate of the extracted strategy. As a result, the adaptation strategies extracted by proposed system are exactly operated, and the extraction method of proposed system shows higher reuse rate than a previous method.

In this knowledge-based society of this age, librarianship takes a professional position and requires essential principles of ethics that has to be observed. Therefore, library associations and professional communities all over the world have released criteria and code of ethics to make their professional positions to keep. This research investigated and analyzed the codes of ethics for librarians in United States, Great Britain, Japan, and South Korea which are based on the mission of each library of each country. Based on these analysis and comparison, this research proposed more advanced codes of ethics for South Korea. The proposed model of codes of ethics consists of two parts: ethics for information and ethics for professional positions. The ethics for information contains six essential elements: equal access and services for information, denial of inspection, protection of privacy, neutralization of librarian, and security of intellectual freedom. The ethics for professional positions consists of 8 essential aspects: exclusion of personal benefit, continuous efforts for developing knowledge, keep the professional position, conflicts between professional task and organization, relationship with co-workers, ensure the conditions of rights and welfare for employees, cooperations among libraries, and contribution for creation of new culture.

When people who are not expert need remodeling or interior construction in their houses or buildings, there might be several problems. A lack of knowledge and unforeseen can lead expressing wrong design or construction that they did not want. The aim on this thesis is to develop virtual construction designing experience web-site in order to help non-professional to predict the actual construction working result by self-construction design, provided by virtual reality program, sharing knowledge of architectural design and materials on internet to solve certain problems. The way of study is using case of virtual reality technology which is practically using in architecture era recently; in construction design, deducting realizable virtual reality technology of limitation and its solution; analyze case of construction designing program which is currently used by professionals; constitute required essential functions as UI when constructing. Followed by result of study, as a proposal, in service, technical, and UI sectors are the way to construct its objectives for internet based virtual construction experience web-site.

The development of Semantic Web basically requires knowledge induced from the formalization and semantization of information, and thus ontology should be introduced as a knowledgization tool. URI(Universal Resource Identifier) is an indispensible scheme to uniquely indicate individuals on ontology. However, it is difficult to find the use cases of URI in real data including science & technology publications. This paper describes the method to construct human resources based on URI which are the critical components on national R&D reference information ontology. We use co-authors, e-mails, publication date, and affiliation for discriminating authors with the same strings. HRST is referred to acquire human resource URIs. We expect the human resources would be adopted to outcome analysis applications such as researcher network analysis and outcome statistics.

The research analysis will be proceeded with a specific question: The kind of endeavors the ICT providers must focus on within the ICT industry's Schumpeterian pattern of using barriers of knowledge during the rapid technological transformation and pursuing appropriability of guaranteed opportunities. The study was carried out by targeting and conducting empirical observations on the proliferation of technological patent applications made by ICT companies among approximately 5,700 listed North American corporations. The risk of arising cases, in which late-coming non-ICT companies adopt and participate in the technical pertinence and concept derived from the technological advent, will be treated as an independent variable in a survival analysis. Through this analysis, innovative technological attempts and absorption capabilities indicate significance.

The future society requires not only knowledge but also various competencies, including creativity, cooperative spirit and integrated thinking. This research develops a program for integrating mathematics and information science to enhance important mathematical competencies such as problem-solving and communication. This program does not require much prior knowledge, can be motivated using everyday language and easy-to-access tools, and is based on creative problem-solving activities with multilateral cooperation. The usefulness and rigor of mathematics are emphasized as the number of participants increases in the activities, and theoretical principles stem from the matrix theory over finite fields. Moreover, the activity highlights a connection with error-correcting codes, an important topic in information science. We expect that the real-world contexts of this program contribute to enhancing mathematical communication competence and providing an opportunity to experience the values of mathematics and that this program to be accessible to teachers since coding is not included.
