Organizations are increasingly adopting Knowledge Management Systems (KMS) to effectively manage knowledge within the organization and realize firm and operational level benefits. However, many KMS implementations fail to yield desired outcomes due to the lack of understanding of the antecedent of successful knowledge management. Prior studies have established that organizational cultural values are one of the key enablers of knowledge management. We develop a computational model of organizational knowledge processes and employ simulations to examine the impact of KMS in different organizational cultural settings. We find that cultural values that govern the employees' predisposition towards seeking knowledge from others have a greater influence on KMS effectiveness than those that govern the employees' attitudes towards sharing their knowledge with others. We also find that organizations with cultures that foster high levels knowledge sharing behaviors can expect performance gains if KMS implementations incorporate knowledge seeking activities into the employees' work processes.

While past knowledge management researches have focused on conceptualization and strategic implications, knowledge asset researches attempt to provide practical guidelines for companies. However, each research classifies knowledge asset from its own perspective, and thus it is not a trivial task to leverage consistent and inclusive criteria in managing corporate knowledge asset. The objective of this paper is to develop a knowledge asset classification schema on the basis of the three business functions: customer relationship management, product innovation, and infrastructure management. To demonstrate the feasibility of our schema, it has been applied to 9 Korean corporations. Knowledge assets are evaluated according to core capabilities, which are main drivers of sustainable competitive advantages. The results of case study show that the leveraged classification schema reflects current knowledge asset management and characteristics of corporations. Our finding is that most top-quality knowledge management corporations are likely to develop well-balanced knowledge asset.

This paper aims to investigate a dynamic mechanism underlying the process of knowledge creation and growth with a focus on the 'knowledge-friendly culture' conceptually coined by Davenport and Prusak in 2000. To achieve this objective, key attributes of knowledge are first identified by exploring the generic characteristics and information and interpreting the definitions of knowledge, from which four modes of knowledge growth (Socialization, Externalization, Combination, Internalization) are delineated into a dynamic SECI model by identifying cultural attributes underlying each mode and modeling their casual relationships based on the systems thinking. Further, a series of sensitivity analysis through computer simulation were made to find how 'knowledge-friendly' cultural factors affect the knowledge growth. It is found that individual knowledge is most influenced by organization's cohesion whereas organizational knowledge is most affected by the openness of organization.

The current study investigates the relationship of antecedents of flow, organizational commitment, knowledge sharing, information technology usage for knowledge sharing, and job satisfaction of organizational employees. This study analyze the effects of psychological states of employees both on affective states of them and on knowledge sharing by applying the internet-based flow theory to knowledge sharing. The antecedents of flow are found to have positive effects on organizational commitment. In addition, it is found that organizational commitment has a positive effect on knowledge sharing, information technology usage for knowledge sharing, and job satisfaction. While it is found that knowledge sharing has a positive effect on job satisfaction, it is found that information technology usage for knowledge sharing does not have an effect on job satisfaction, but have a positive effect on knowledge sharing. The result of this study would not only provide significant insights to knowledge management researchers and practitioners but also contribute to applying the flow theory to knowledge sharing.

시맨틱 웹이나 지식기반 시스템에서 지식 검색의 핵심 컴포넌트는 온톨로지이다. 하지만 현재 실용적인 온톨로지가 구축된 경우를 찾아보기는 어렴다. 실용적인 온톨로지 구축을 위해서는 특정 도메인의 지식 전문가에 의한 지식의 개념화와 온톨로지 설계자에 의한 지식의 명세화가 필요하며 이를 바탕으로 개발 팀원들 사이에 공유할 수 있는 자세한 온톨로지 생성 가이드라인이 필요하다. 그러나 기존의 온톨로지 생성 방법론은 은톨로지 구축 프로세스의 단계들을 상위 수준에서 나열하는 절차 중심의 방법론이다 본 논문에서는 철학 학문의 지식을 구조화하는 실용적인 온톨로지를 구축하는 방법으로서 텍스트 내용에 들어있는 지식을 온톨로지로 생성하는 토픽맵 기반의 덱스트 온톨로지 방법론을 제시하였다. 이 방법론은 지식 자원으로부터 지식을 분석하고 추출하는 온톨로지 모델링 단계와 형식 언어와 데이타 모델을 이용하여 온톨로지를 생성하는 온톨로지 구현 단계로 구성된다. 방법론과 함께 본 논문에서는 철학 온톨로지에 기반한 철학 지식 검색의 효율성을 보이기 위해 철학 지식 포털을 구현하였다.

Purpose: The purpose of this study was to analyze the effects of simulation-based training on nursing students' knowledge and ability to perform advanced cardiovascular life support. Methods: A nonequivalent control group non-synchronized design was used. The participants were, in total, 59 junior college nursing students (experimental group: 30, control group: 29). The data were analyzed with a ${\chi}^2$-test, independent t-tests, and analysis of covariance (ANCOVA) using IBM SPSS Statistics 23 program. Results: The experimental group ($80.8{\pm}8.4$), who received simulation-based advanced cardiovascular life support education, showed a higher level of knowledge of advanced cardiovascular life support than the control group ($75.0{\pm}9.9$), who received lecture-based education. In addition, the experimental group ($106.4{\pm}11.9$) showed a higher level of ability to perform advanced cardiovascular life support than the control group ($86.5{\pm}9.9$). Conclusion: Simulation-based advanced cardiovascular life support education was more effective for increasing the knowledge and performance ability of college students than lecture-based education. Therefore, simulation-based training should be used to improve the knowledge and ability of nursing students and should be applied with reinforced systematic education programs.

This study evaluates nutrition knowledge, dietary behaviors and food group acceptability based on a sample of 514 of new employees in Gyeonggi area. Among the respondents, 70.6% of male, and their age was 30.7 Most were college graduates (94.9%) and unmarried (86.3%). Based on the BMI males tended to be overweight, whereas females, normal. In terms of health consciousness based on five-point Likert-type scale, the average score for the health status was 4.18 indicating good health, and health attention was 4.88 indicating high health attention. Dietary behaviors were evaluated using five-point Likert-type scale. According to the results, the total score for regular diet based on 5 items was 9.6; that for a balanced diet based on 7 items was 22.2; and that for practical diet action based on 8 items was 22.3. That is, the respondents were on an irregular diet but tried to balanced diet through appropriate diet action. Food acceptability was evaluated using a five-point Likert scale ranging from "strongly dislike(1)" to "strongly like(5)". The score of meat group was 3.67; that for the fish 3.43; and that for the vegetable group was 2.86. Females were slightly more like to accept fruits 3.60 than males 3.48;(p<0.05). The total score for nutrition knowledge based on 35 items was 20.5. A balanced diet was correlated with egg acceptability (p<0.01); energy-related knowledge with confectionery preferences (p<0.05); and vitamin knowledge, with snack affinity (p<0.05). Health attention was negatively correlated with seafood preferences for male(p<0.05) and with snacks for females(p<0.05). The respondents were strongly interested in and aware of their health, but this did not lead to their food preferences. These results suggests that dietary habits can lead to nutritional balance for maintaining the health of employees.

The purposes of this study were to segment outdoor wear market based on consumer knowledge and consumer demand for function/design development, and to examine the differences of demographic characteristics and purchase behavior among the segmented markets. Data were collected using a questionnaire survey. Respondents were adults aged over 20 and who have experiences of purchasing outdoor wear. The survey was made up of the questions on consumer knowledge to outdoor wear, consumer demand for product development, purchase behavior, and demographic characteristics. Frequency analysis, descriptive analysis and chi-squared test were used to conduct the data analysis on 454 questionnaires. The results of this study were as follows. It showed that the consumer knowledge was a little high and the consumer demands for function/design development were high. Six segmented markets based on consumer knowledge and consumer demand for function development were significantly different in terms of gender, income, purchase frequency and total item holdings. Also, six segmented markets based on consumer knowledge and consumer demand for design development were significantly different in terms of age, income, purchase frequency, purchase objective, purchase place and total item holdings. Compared to the segmented markets based on the consumer demands for product development, the gender was the key of the marketing strategies for the segmented markets by the consumer demand for function development while the age was the one in the markets by the consumer demand for design development. After considering all the results, the characteristics of the segmented markets were made out and the marketing strategies were established.
