In recent, library is considered as an integrated knowledge convergence center that can respond to various requests about information service of users. Therefor it is necessary to establish a novel information system based on information communications technologies of the era. In other words, it is currently required to develop mobile information service available in portable devices such as smart phones or tablet PCs, and to establish information system reflecting cloud computing, SaaS, Annotation, and Library 2.0 etc. In this paper we design and implement a library information system using collective intelligence and cloud computing. This information system can be adapted for the varieties of mobile service paradigm and abruptly increasing amount of electronic materials. Advantages of this concept model are resource sharing, multi-tenant supporting, configuration, and meta-data supporting etc. In addition it can offer software on-demand type user services. In order to test the performance of our system, we perform an effectiveness analysis and TTA authentication test. The average response time corresponding to variance of data reveals 0.692 seconds which is very good performance in timing effectiveness point of view. And we detect maturity level-3 or 4 authentication in TTA tests such as SaaS maturity, performance, and application programs.

Recently, construction industry has won an increasing number of orders for overseas construction projects, thereby achieving an external growth, but its competiveness is concentrated on the construction execution field. In particular, the plant field occupies most of the entire orders, which are concentrated regionally in the Middle East and Asia. In addition, low-cost orders are frequently caused by excessive competition. But its high value-added construction engineering(Below, CE) field's overseas market share and technological capacity are very low. Also, technological competiveness, in terms of order amount and other factors, is deepening in polarization between large CE companies and small and medium-sized CE firms. It is noted that the existing CE information systems mostly simply accumulate data such as design and specification standards and provide the information thereon to users, and thus have yet to provide the information essential for the CE and support such efforts. This study sought to prepare a system designed for sharing outstanding design documents information necessary for the CE industry, by category of construction so as to support the technological enhancement of the CE field. Toward that end, this study presented measures for constructing the system and services designed to exchange and share the outstanding design documents information and know-how by construction category necessary between ordering agencies and CE companies.

The goal of this study is to explore and draw implicaitons from international and domestic media and information literacy (MIL) policies and educational systems. To this end, international policy documents issued by UNESCO, IFLA, OECD, and the EU as well as domestic South Korean laws and policies related to MIL and the fuctions of public libraries and related institutions were analyzed. The findings show that international organizations recognize public libraries as institutions that are responsible for providing information access and supporting knowledge sharing for citizens within and outside of formal education systems. Additionally, public libraries are seen as institutions responsible for supporting lifelong learning and civic education, as well as improving media, information, and digital literacy skills of their communities. In South Korea, the Library Act gives public libraries and librarians responsibility for improving citizens' MIL to support the public's right to know and to narrow the information gap. However, the functions of public libraries and librarians in South Korea have been limited or excluded in the domestic MIL policies. This study concludes that public libraries and librarians are responsible for reducing the information gap among citizens and should actively participate in policy development to improve citizens' MIL skills.

The Semantic Web and its related technologies have been opening the era of information sharing via the Web. There are, however, several huddles still to overcome in the new era, and one of the major huddles is the issue of information integration, unless a single unified and huge ontology could be built and used which could address everything in the world. Particularly in the e-business area, the problem of information integration is of a great concern for product search and comparison at various Internet shopping sites and e-marketplaces. To overcome this problem, we proposed an ontology-driven mapping algorithm between heterogeneous product classification and description frameworks. We also peformed a comparative evaluation of the proposed mapping algorithm against a well-Down ontology mapping tool, PROMPT.

This study aims to investigate the research equipment establishing relationship by looking at research equipment information transfer that follows the network's structural and positional characteristics and the research institute's responsibilities to increase the possibility of research equipment usage by using the SNA(Social Network Analysis) method. Consequently, with the given structural characteristics of research institute, it can be concluded that because of its low density, it appears to be difficult to transfer research equipment information within the network. Government-funded research institutes that can effectively deliver research equipment information within the network system through comparison positional characteristics are ETRI, KITECH, KRICT, Sungkyungwan University, and Kyungbook National University. In addition, a virtualization node not only invigorates the network system but also acts as an intermediary factor to effectively deliver research equipment information. As results, there can be three conceivable alternatives to increase the possibility of research equipment usage. Those includes: 1. policy to encourage relationship building among research institutes 2. utilizing suitable institutes for effective delivery of research equipment information and lastly, 3. establishing a virtual intermediary institute for information sharing and utilization of isolated institutes' research equipments.

To realize advanced collaboration environments for knowledge workers distributed geographically, there are extensive researches in ubiquitous computing environments. Especially, to cope with several known problems in traditional collaboration tools such as limited display resolution, uncomfortable shared documentation, difficult operation of collaboration environments, various approaches are attempted in the aspect of framework design. In this paper, we design a framework for collaboration environments covering hardware/software/networking architecture to flexibly coordinate a set of collaboration services and devices considering users' expectation and node capabilities. Based on the proposed framework, we develop the collaboration environment supporting the interactive networked tiled display enabling media/data sharing via networking, display interaction using pointing/tracking, and high-resolution tiled display. Finally the demonstration of the developed prototype is introduced to prove the possibility of its realization.

Aerospace industry is a combination of high technologies which has several characteristics such as product reliability, precision, light weight, and energy efficiency. Nowadays, each country is trying to invigorating knowledge and information sharing between the companies for the synergy effect of aerospace industry. However, the research and empirical analysis on the vitalization of aerospace industry cluster are insufficient. Therefore, this study aims to firstly classify the supporting functions of government for aerospace industry cluster into five types by analyzing existing literatures and status reports issued by government. Secondly, companies are surveyed on the five classified types of supporting functions by questionnaire. Questionnaire survey responded by 30 aerospace companies in Gyeongnam aerospace industry cluster are analyzed. Quantitative analysis methods were used for statistical analysis. Based on the analysis, improvement directions of government supporting functions are suggested. The results of this study is expected to help policy making for invigorating the aerospace industry cluster.

We need to seek after new direction and order of design that puts more value on the spirits and culture of human beings in the 21st century, creating a new, all-inclusive value in which individual human being, the society and the environment can co-exist in a peaceful relationship by overcoming the materialistic, analytical, competitive, and differentiated values of traditional industrial society. The aim of this study, then, is to present a new method of design that can meet the demands of the 21st century in a civic age of information, knowledge and culture, by focusing on Monistic ideals derived from a deeply rooted Oriental philosophy. The concept of Monism is embodied by a mind set that treasures the benefit to others over rewards to the self, puts more importance on the spiritual life hidden behind physical phenomena, thinks more of what lacks than what exceeds, elevates the mind over the body, and seeks after beauty via a total harmony of balance and development that can be feasible only by combining all these elements. Ultimately, the new design principle based on the Monism consists of three basic elements: (1) identification of the subject and the object between things under the perception that all things are one (Unification); (2) the ability that helps things exist with appropriate beauty maintaining balance and stability (Harmony); and (3) the attitude of sharing to maintain sustainable vitality by filling up what lacks or is missing in a whole(Change).

This study focuses on the role of supplier's organizational learning capacity in creating the outcomes of technological innovation based on buyer-supplier collaboration. In doing so, the study is carried out through mediating effect analysis using 221 small and medium enterprises among Korean manufacturers. As a result of empirical tests, buyer's indirect supports(knowledge, know-how, value, information sharing) have significant and positive effects on the outcomes of technological innovation, whereas direct supports(technical staff support, machine tools and test equipments support, education for facility utilization) show no statistical significance. In addition, a further test for mediation effects reveals that a full mediation exists between supplier learning capacity and buyer's direct support, while there is a partial medication effect for buyer's indirect support. The findings suggest that buyer's indirect support can take on more important role to enhance the outcomes of supplier's technological innovation.

The ontology is the underlying knowledge base to create the semantic web. Prerequisites for the success of the semantic web include widespread uses/sharing/merging of ontologies. In addition, it is very crucial to secure the integrity of ontology instances such as instance-identifying/referring integrity, and attribute domain constraints. In terms of ensuring instance-identifying integrity, OWL provides owl:sameAs property which is used to connect two separate ontology instances in order to represent that the two instances are the same. Recent semantic web works, however, have not sufficiently investigated the issues one may face in applying owl:sameAs to real semantic web applications. This study introduces our experiences of sameAs in developing a semantic web service framework for a research domain.
