Knowledge management has garnered attention due to its role of maintaining competitive advantage. Creating and sharing knowledge is an essential part of managing knowledge. However, the best knowledge is underutilized because employees tend to seek knowledge through their informal networks, not reach out to other sources for obtaining the best knowledge. Prior studies on informal networks pointed out a negative influence of heavy reliance on learning through informal networks but they paid little attention to a structure of informal networks and its impacts on diffusion of knowledge. The aim of our study is to show impacts of informal network on knowledge management by employing a network structure and investigating diffusion of knowledge within it. Our study found out that performance of learning becomes lower in a highly clustered network. Creating random links such as serendipitous learning can improve performance of knowledge management. When employees rely on a knowledge management system, creating random links is not necessary. Costs of adopting knowledge affect performance of knowledge management.

Objectives: Unprotected leisure time exposure to ultraviolet radiation from the sun or artificial tanning beds is the most important environmental risk factor for melanoma, a malignant skin cancer with increasing incidences over the past decades. The aim of the present study was to assess the impact of skin health information provided by several sources and different publishing issues on knowledge, risk perception, and sun protective behavior of sunbathers. Methods: A cross-sectional questionnaire survey was conducted among Austrian residents (n=563) spending leisure time outdoors in August 2010. Results: Print media, television, and family were perceived as the most relevant sources of information on skin health, whereas the source physician was only ranked as fourth important source. Compared to other sources, information provided by doctors positively influenced participants' knowledge on skin risk and sun protective behavior resulting in higher scores in the knowledge test (p=0.009), higher risk perception (p<0.001), and more sun protection (p<0.001). Regarding gender differences, internet was more often used by males as health information source, whereas females were more familiar with printed information material in general. Conclusions: The results of this survey put emphasis on the demand for information provided by medical professionals in order to attain effective, long-lasting promotion of photoprotective habits.

This review article addresses the role of safety professionals in the diffusion strategies for predictive analytics for safety performance. The article explores the models, definitions, roles, and relationships of safety professionals in knowledge application, access, management, and leadership in safety analytics. The article addresses challenges safety professionals face when integrating safety analytics in organizational settings in four operations areas: application, technology, management, and strategy. A review of existing conventional safety data sources (safety data, internal data, external data, and context data) is briefly summarized as a baseline. For each of these data sources, the article points out how emerging analytic data sources (such as Industry 4.0 and the Internet of Things) broaden and challenge the scope of work and operational roles throughout an organization. In doing so, the article defines four perspectives on the integration of predictive analytics into organizational safety practice: the programmatic perspective, the technological perspective, the sociocultural perspective, and knowledge-organization perspective. The article posits a four-level, organizational knowledge-skills-abilities matrix for analytics integration, indicating key organizational capacities needed for each area. The work shows the benefits of organizational alignment, clear stakeholder categorization, and the ability to predict future safety performance.

Virtual project organization may be recognized as one of the promising business models in which many knowledge sources externalize through cross boundaries of knowledge-based organizations. This paper proposes a knowledge competence evaluation of virtual project organization based on the following perspectives: 1) Individual knowledge perspective, 2) Activity-oriented knowledge perspective, and 3) Knowledge-driven social network perspective. In the framework, individual knowledge competence having experienced or learned from knowledge-based activities and virtual networks in the project, should be evaluated according to the assumption that knowledge and collaboration competence depends on the activities and networks acquired proportionally by the past participation to projects. An illustrative SI example is given in order to validate the proposed evaluation and computing procedure.

This paper investigates how internal knowledge dependency and its interaction with external knowledge adoption affect innovation performance in Korean companies. We categorize innovation performance into exploratory innovation and exploitative innovation. Especially, we examine business group effects as group headquarters and sister subsidiaries holistically form the boundary of the firm. Our empirical results first suggest that the degree of internal knowledge dependency is positively associated with exploitative innovation, but negatively with exploratory innovation. Second, internal knowledge dependency is more negatively related to exploratory innovation in independent firms than in business group affiliates. Third, independent firms' adoption of external knowledge tends to strengthen the positive relationship between internal knowledge dependency and exploitative innovation. Finally, exploitative external knowledge search appears to strengthen the negative relationship between internal knowledge dependency and exploratory innovation in both types of firms.

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.

This study was conducted to assess the information of food safety by college students according to mass-media reports. To accomplish this, a survey was conducted to investigate the preference and reliability, of primary mass-media sources of BSE information, and BSE-related knowledge of college students. The most common sources of media by male and female students were terrestrial television(60%), the internet(21%) and newspapers(11%) and terrestrial television(60%), newspapers (18%) and the internet(17%), respectively. The reliability of media of male students were terrestrial television(53%) and the internet(40%), while for female students these values were terrestrial television(55%) and internet(37%), respectively. In the case of male students, the primary sources of information regarding BSE were terrestrial television(54%) and the internet(38%), but for female students the primary sources were terrestrial television(57%) and the internet(37%). Both male and female students were found to have less knowledge regarding prions, SRM, and MM type genes associated with BSE when compared to the other factors associated with this disease. In addition, the important determining factors for the food purchase of male and female students both were the orders of taste, hygiene, price. The preferences for meats and the beef-alternative meats of male and female students were the orders of pork, chicken. Based on these results, greater efforts should be made to provide meaningful information regarding the safe production and distribution of meats.

Objectives: The aim of this study was to assess knowledge, attitudes, and practices regarding tuberculosis (TB) in the general population in Timor-Leste. Methods: In the nationally representative cross-sectional 2016 Timor-Leste Demographic and Health Survey, 4622 men (aged 15-59 years) and 12 607 women (aged 15-49 years) were randomly selected using stratified multistage sampling and interviewed. Results: Overall, 66.9% of men and 62.8% of women were aware of TB, 4.4% of men and 12.6% of women had TB courtesy stigma, and 83.3% of men and 88.6% of women reported intention to receive TB treatment. The $mean{\pm}standard$ deviation overall TB knowledge score was $3.9{\pm}2.0$ (out of 8) among men and $3.0{\pm}1.8$ among women. In a multivariable linear regression analysis, among both men and women, older age, higher education, rural residence, and sources of TB information (family/friends, school/workplace, health care provider, Internet, television, and newspaper) were associated with higher TB knowledge scores. In addition, among women, higher wealth status and having heard about TB from the radio were associated with higher TB knowledge scores. Negative associations with TB courtesy stigma were found for urban residence and having heard about TB from family or friends among men, and for older age, higher TB knowledge, and TB information sources (family/friends and school/workplace) among women. Among both men and women, higher TB knowledge scores and having heard of TB from a health care provider were associated with intention to receive TB treatment. Conclusions: This study identified socio-demographic risk factors for deficiences in population-based TB knowledge in Timor-Leste; these findings should be considered when designing TB communication, prevention, and control strategies.

An intelligent system embedded with multiple sources of knowledge may provide more robust intelligence with highly ill structured problems than the system with a single source of knowledge. This paper proposes the hybrid knowledge integration mechanism that yields the cooperated knowledge by integrating expert, user, and machine knowledge within the fuzzy logic-driven framework, and then refines it with a genetic algorithm (GA) to enhance the reasoning performance. The proposed knowledge integration mechanism is applied for the prediction of Korea stock price index (KOSPI). Empirical results show that the proposed mechanism can make an intelligent system with the more adaptable and robust intelligence.
