This study compared the college students' dietary behavior for processed foods, who will be the main consumers in the future and looked for the measures to understand and establish the right food labeling system by surveying the level of understanding and utilization of food labeling. The data was analysed by SPSS win 17.0 program, and the results are as follows. For the standard of selecting processed foods, the group with high nutrition knowledge considered the reliability of foods as important and the group with low nutrition knowledge considered the products introduced in TV commercial as important. When purchasing processed foods, the group with high nutrition knowledge considered nutrition, taste, price, appearance(shape), and the consumable period more than the group with low nutrition knowledge. For trans fat, the group with high nutrition knowledge learned more about it than the group with low nutrition knowledge. The ratio of confirming food nutrition label was higher in the group with high nutrition knowledge. Regarding the level of confirming individual food labels, the highest level was for milk and dairy products. And there was significant difference for the processed products of meat, cookies, bread and noodles. It was found that the level of confirmation was higher in the group with high nutrition knowledge. And the most important indication for individual food product was the consumable period. To preserve the purchased foods, the group with high nutrition knowledge preserve the foods in line with the description written on the food cover sheet, and this group used to return or exchange the products when they found them spoiled or purchased by mistake. The group with high nutrition knowledge knew more about the nutrition indication than the group with low nutrition knowledge. The necessity of nutrition indication for processed foods and the need of education and PR(Public Relation) were acknowledged higher in the group with high nutrition knowledge. For the effect of nutrition indication, it showed that the group with high nutrition knowledge thought it would improve the quality and the group with low nutrition knowledge thought it would be helpful when comparing the product with others. The group with high nutrition knowledge showed higher understanding level about nutrition indication than the group with low nutrition knowledge.

This study was conducted to examine arthritis patients' knowledge level and its related factors. Data were collected from 100 people who suffered from arthritis in Seoul, Busan, Daegu, Daejun, Junjoo, and Pohang from June 1, 2000 to August 31, 2000. The results of this study are summarized as follows. 1. 61.0％ of the subjects was female. The incidence rate of arthritis was higher in the higher age group, lower educated group, and thinner group. In the case of male, the incidence rate was higher in the groups of single, residents in big cities, and technicians. In the case of female, it was higher in the groups of the married, residents in towns or villages, and housewives. 2. Among the sources of obtaining the knowledge related to arthritis, 38.0％ of the respondents obtained the knowledge from physicians and 24.1 ％ got it from TV or Radio. 14.6％ of them obtained it from family members, neighbors, and friends and 14.3％ got it from newspapers, magazines, and pamphlets. Only 5.8％ of them obtained the knowledge from pharmacists. The sources showed significant difference in the variables of age, occupation, marital status, religion, place of residence, and education level. 3. 47.2％ of them thought that education related to arthritis was needed without fail, while 12.5％ thought that it was not necessary. In the question related to concern about arthritis, ‘no concern’ was 31.2％, while ‘concern’ was 7.8％ and ‘a little concern’ was 45.1 ％. 4. The knowledge level of arthritis was 7.35 ± 1.51 points on the basis of 11 points. It showed significant difference in the variables of age, occupation, education level, and economic status. 5. The knowledge was influenced by the variables of economic status, necessity of publicity, treatment period, occupation, education level, and age. The arthritis patients did not have enough knowledge of arthritis because the education was not provided well for them. Therefore, related professionals and organizations must develop education program of arthritis in order to educate them.

Building a knowledge base effectively has been an important research area in the expert systems field. A variety of approaches have been studied including rules, semantic networks, and frames to represent the knowledge base for expert systems. As the size and complexity of the knowledge base get larger and more complicated, the integration of knowledge based with database technology cecomes more important to process the large amount of data. However, relational database management systems show many limitations in handing the complicated human knowledge due to its simple two dimensional table structure. In this paper, we propose Object-Oriented Knowledge Store (OOKS), a knowledge base model on the basis of a frame sturcture using an object-oriented database. In the proposed model, managing rules for inferencing and facts about objects in one uniform structure, knowledge and data can be tightly coupled and the performance of reasoning can be improved. For building a knowledge base, a knowledge script file representing rules and facts is used and the script file is transferred into a frame structure in database systems. Specifically, designing a frame structure in the database model as it is, it can facilitate management and utilization of knowledge in expert systems. To test the appropriateness of the proposed knowledge base model, a prototype system has been developed using a commercial ODBMS called ObjectStore and C++ programming language.

It is more important than ever for companies to distinguish themselves through knowledge management strategies. Without a constant creation of knowledge, a business is condemned to poor performance. However, it is still unclear how these strategies affect knowledge creation. Knowledge management strategies can be categorized as being either human or system oriented. This paper proposes a model to illustrate the link between the strategies and its creating process. It is found that human strategy is more likely to be effective for socialization while system strategy is more likely to be effective for combination. Furthermore, the result suggests that managers should adjust knowledge management strategies in view of the characteristics of their departments.

As an interest in the efficiency of public sector expenditures has spread across the world, Korea has operated a self-evaluation system for government projects as a part of the performance-based budget system. However, an evaluation system for public information technology project has been criticized for its lack of validity, which stems from the uniformity of performance management. This study draws insight from knowledge management literature in an attempt to address the problems with the extant performance evaluation system in public agencies. To realize benefits from IT investment, an agency needs to develop its own performance management model for information systems projects, with a focus on the interaction of IT and organizational system. The knowledge management-based framework for IT projects was verified through a case study, with which we discussed the applicability of knowledge management to the evaluation of public information systems projects.

The purpose of this study is to explore the process of knowledge creation at the infusion stage in IT adoption. Because of the lack of the prior research on the infusion and the process of individual knowledge creation we employed Grounded Theory Method which is a qualitative method for building a theory inductively. Collecting and analyzing data from 13 knowledge workers including medical doctors, project managers, and bankers, a process model is developed through the serial process of open, axial and selective coding. We conceptualized the knlowledge creation at the infusion stage as a social process where knowledge is expressed through private and public justifications. This study also found that organizational politics, top management supports, and organization strategy are important factors facilitating the knowledge creation process.

Online brand communities have become a major component of marketing strategy given that these communities encourage participation and share the culture of Web 2.0 core concepts to Internet users. This study investigated the effects of social capital and knowledge quality on the success of online brand communities. A research model suggests that trust among members and the identification derived from social capital theory and knowledge quality influence individual community participation; knowledge quality also influences brand trust. In turn, community participation and brand trust develop brand loyalty. The model was empirically analyzed using structural equation modeling with data from online brand community members in Korea. The results indicate that identification and knowledge quality significantly affects brand trust and brand loyalty through community participation. This study provides a basis for developing a success model for online brand communities. Also, this study identifies a new role of knowledge quality in an online brand community context.

Knowledge sharing occurs through voluntary interactions between human actors. In this paper, from the perspective of social interaction, the effect of transactive memory capability and social capital (bridging social capital and bonding social capital) on knowledge sharing intention was analyzed, and tenure was demonstrated as a moderating factor that can strengthen their relationship. Therefore, the results of this study are summarized as follows. First, it was verified that the transactive memory capability had a significant positive effect on the knowledge sharing intention. Second, it was found that the bridging social capital and bonding social capital held by individuals had a significant positive effect on knowledge sharing intention. Social capital is understood to form an individual's voluntary motivation for knowledge sharing. Third, it was verified that the moderating effect of tenure suggested in this study was not significant. Based on the results of this study, implications and future research directions were presented.

The purpose of this research is to find a better knowledge service R&D management process. There are four basic characteristics in service : intangibility, inseparability, inconsistency, and no inventory. These intrinsic characteristics require us to change the traditional manufacturing sector based R&D management process. It is necessary to develop an effective knowledge service R&D management model to improve the competitiveness of the service industry and Korean economy. A model case knowledge service R&D has been performed to find a better R&D management model. The whole cycle of R&D process, such as planning, selection, performing, and evaluation has been reviewed by real experience. Several important aspects of R&D process are compared between manufacturing R&D and service R&D. A knowledge service R&D management framework has been suggested. The results of this research can be used for building a better service R&D management process.

With the advent of knowledge-based economy and information society, information and telecommunications(IT) industry is reckoned as the crucial sector for the creation and diffusion of technological knowledge. In this study, we analyze the process of 'industrialization of IT'and 'informatization of industries' based on the technology linkage structure, or technological knowledge network. The former is defined as the process whereby IT industry absorbs technological knowledge from other industries to grow as an independent industrial sector. The latter is defined as the process whereby other industries adopt IT technology to enhance productivity and upgrade industrial structure, We employ the R&D stock as a proxy for technological knowledge of respective industries and measure the flow of technological knowledge between industries in terms of I/O relationship. By applying the network analysis, we examine the changing pattern of technology linkage structure of the Korean industry throughout the years from 1983 to 1997. Some policy implications are presented based on the findings from the analysis.
