With an advent of recent knowledge-based society, the interest in intellectual property has increased. Firms have tired to result in productive outcomes through continuous innovative activity. Especially, ICT firms which lead high-tech industry have tried to manage intellectual property more systematically. Firm's interest in the patent has increased in order to manage the innovative activity and Knowledge property. The patent involves not only simple information but also important values as information of technology, management and right. Moreover, as the patent has the detailed contents regarding technology development activity, it is regarded as valuable data. The patent which reflects technology spread and research outcomes and business performances are closely interrelated as the patent is considered as a significant the level of firm's innovation. As the patent information which represents companies' intellectual capital is accumulated continuously, it has become possible to do quantitative analysis. The advantages of patent in the related industry information and it's standardize information can be easily obtained. Through the patent, the flow of knowledge can be determined. The patent information can analyze in various levels from patent to nation. The patent information is used to analyze technical status and the effects on performance. The patent which has a high frequency of citation refers to having high technological values. Analyzing the patent information contains both citation index analysis using the number of citation and network analysis using citation relationship. Network analysis can provide the information on the flows of knowledge and technological changes, and it can show future research direction. Studies using the patent citation analysis vary academically and practically. For the citation index research, studies to analyze influential big patent has been conducted, and for the network analysis research, studies to find out the flows of technology in a certain industry has been conducted. Social network analysis is applied not only in the sociology, but also in a field of management consulting and company's knowledge management. Research of how the company's network position has an impact on business performances has been conducted from various aspects in a field of network analysis. Social network analysis can be based on the visual forms. Network indicators are available through the quantitative analysis. Social network analysis is used when analyzing outcomes in terms of the position of network. Social network analysis focuses largely on centrality and structural holes. Centrality indicates that actors having central positions among other actors have an advantage to exert stronger influence for exchange relationship. Degree centrality, betweenness centrality and closeness centrality are used for centrality analysis. Structural holes refer to an empty place in social structure and are defined as efficiency and constraints. This study stresses and analyzes firms' network in terms of the patent and how network characteristics have an influence on business performances. For the purpose of doing this, seventy-four ICT companies listed in S&P500 are chosen for the sample. UCINET6 is used to analyze the network structural characteristics such as outdegree centrality, betweenness centrality and efficiency. Then, regression analysis test is conducted to find out how these network characteristics are related to business performance. It is found that each network index has significant impacts on net income, i.e. business performance. However, it is found that efficiency is negatively associated with business performance. As the efficiency increases, net income decreases and it has a negative impact on business performances. Furthermore, it is shown that betweenness centrality solely has statistically significance for the multiple regression analysis with three network indexes. The patent citation network analysis shows the flows of knowledge between firms, and it can be expected to contribute to company's management strategies by analyzing company's network structural positions.

The purpose of this study was to survey the knowledge and awareness of dental hygienists and dental hygiene students about hepatitis B in an attempt to lay the solid foundation for the prevention of hepatitis B and infection control, as dental hygienists were highly likely to be exposed to HBV during job performance. The findings of the study were as follows: 1. 32.5% of the dental hygienists and 15.6% of the dental hygiene students were aware of their own HBsAg and HBsAb states. The dental hygienists who were cognizant of the states statistically significantly outnumbered the dental hygiene students who were (p=.000). 2. As for vaccination against hepatitis B, 71.8% of the dental hygienists and 47.3 % of the dental hygiene students were inoculated against it. The dental hygienists who were vaccinated against it outnumbered the dental hygiene students who were, and the disparity between the two was statistically significant (p=.000). 3. In the event of those who were vaccinated against hepatitis B, the dental hygienists were better cognizant than the dental hygiene students of the right time for the vaccination, required vaccination frequency (three times) and confirmation of the formation of hepatitis B antibody (p=.000). 4. Regarding awareness of hepatitis B infection route, the dental hygienists knew significantly better than the dental hygiene students that hepatitis B might be infected via blood (p=.030), sexual relations (p=.000), contaminated needle sticks (p=.000), mothers with hepatitis B positive during delivery (p=.000), toothbrushes/razors (p=.000) and exchange of drinking cups (p=.000). 5. As to the relationship between health status and knowledge on hepatitis B infection route, the respondents who were in bad shape had the best knowledge about that, followed by those in an average state of health and healthy respondents. And the dental hygienists had a significantly better knowledge than the dental hygiene students (p=.001). 6. Just a small number of the dental hygienists and students knew about the hepatitis B-related past experiences of their families, and the gap between the two was insignificant.

Recently the increasing collaborative research requires the remote medical and clinical data sharing and access of external institutions. In this paper, an interoperability framework between Grid and PACS using Web services is proposed and implemented in order to provide flexible and efficient medical data management. The Digital Imaging and Communications in Medicine(DICOM) standard defines medical image data exchange and transfer between PACSs and image databases. However, medical data exchange between hospitals is limited within the trusted and static environments. Moreover, DICOM does not provide medical data management and the Grid middleware does not include standard toolkit to access DICOM data. To address this issue, a Web services-based Grid Service Mediator (WGSM) which provides PACS integration and medical image data management is developed. The WGSM consists of several service mediators such as compress mediator, GridFTP mediator, RFT mediator, MyProxy mediator, MDS mediator, and RLS mediator and others. The proposed Web services-based framework provides user authentication and secure data access between PACSs in collaborative environments. In particular, the WGSM allows ordinary users to access remote PACS data in a simple and efficient manner without any the knowledge about underlying Grid middleware.

In modern society, private securities have developed their capabilities continuously. However, despite the fact that not only security industries have been considerably expanded in quantity, but also plenty of scholars published diverse papers relating to security problems, qualitative growths of private securities have not accomplished fully. Especially, securing the President would not be guaranteed only by PSS(Presidential Security Service). In order to secure the President successfully, it is necessary for all the social parts to strive to protect the President. In this respect, improving private securities, including academic fields, might be critical so as to succeed in securing the President. Without the supports from private securities, there might be lots of security problems in national context. Therefore, this study proposes several policy suggestions for the cooperation among PSS, private security industries and academic fields: (1) Providing a lot of practical knowledge from PSS to college students, (2) Personnel exchange between academic parts and PSS to promote the efficiency of securing the President, (3) Furnishing diverse information and knowledge about security to private securities, (4) Formulating security-searching standards, (5) Expanding educational institutions under PSS.

As the digital information infrastructure is established for the public library system in the contemporary age, expectations and demands surrounding the public library system are growing rapidly as the place of exchange and enjoyment of information and culture, and as the place of life-long learning. In addition, a new kind of information & culture services are needed to meet the demands of contemporary men and women, who are exploring information as the information environment undergoes rapid changes - from increase in the volume of digital publications, to increase in the usefulness of online information resources, to strides made in the media industry. The public library will continue to play its role and function by providing to all users all available information, whether it's available online or offline, whether it's in a physical format or in a digital format. As such, design and management of a space appropriate as a new information environment are needed. It is deemed that an information infrastructure for Daegu that can improve the quality of life in the region and can increase user accessibility to information in this information age is needed, as well as reorganization of the pertinent environment. Therefore more public libraries have to be built in Daegu as a necessity, and it is urgently needed that the information services be expanded through an organic linkage between local libraries such as between the central library and the branch libraries. This paper aims to provide basic data for building of public libraries in Daegu. To establish an information infrastructure for Daegu, a direction is given for the establishment of a local network of public libraries and ways for improvement are explored. This paper is significant in that, first, it helps in the planning of a local network of public libraries, which plays a crucial role in improving accessibility to information as well as the level of their use; and second, it helps in setting up guidelines for spatial configuration of the user space. As for the method, quantitative review of the information environment is to be done by analyzing the present situation of the public library network in Daegu from the perspectives of region, facility, and space, in order to present a method of user-centered spatial configuration that meets the changes in social roles and forms of information in the contemporary society.

The aim of this paper is to explore the role played by the endogenous farming organization sustaining rural community's competitiveness. Nulmi-Ri, Chungdo Kun in Kyongsangbuk-do chosen as a case study area is known to be one of the most competitive rural communities, making a living with a peach farming. This community maintains its competi- tiveness by operating a community-based filming organization which was organised in an endogenous way. Most of individual farmers in this community belong to the farming organization and they have cooperative relationships in the processes of production and distribution. In this respect, the exchange and circulation of knowledge, and collective learning, tend to be significantly taken place between the organization members. Based on the experience of the Nulmi-Ri's endogenous farming organization, we propose some constructive comments for rural community development.

The importance of the call center as a contact point for the enterprise is growing. However, call centers have difficulty with their operating agents due to the agents' lack of knowledge and owing to frequent agent turnover due to downturns in the business, which causes deterioration in the quality of customer service. Therefore, through an N-bank call center case study, we developed a system to reduce the burden of keeping up business knowledge and to improve customer service quality. It is a "real-time agent advisor" system that provides agents with answers to customer questions in real time by combining AI technology for speech recognition, natural language processing, and questions & answers for existing call center information systems, such as a private branch exchange (PBX) and computer telephony integration (CTI). As a result of the case study, we confirmed that the speech recognition system for real-time call analysis and the corpus construction method improves the natural speech processing performance of the query response system. Especially with name entity recognition (NER), the accuracy of the corpus learning improved by 31%. Also, after applying the agent advisor system, the positive feedback rate of agents about the answers from the agent advisor was 93.1%, which proved the system is helpful to the agents.
