Compared to the industrial society, the knowledge-based economy of the 21st century has placed importance on intellectual capital as a sustainable competitive advantage of an organization. The ownership, creation, and interaction of intellectual capital is emerging as the main challenges of the management and, moreover, it might extend to the issue of intellectual capital management. This research found that the exploitation and sharing of knowledge was more efficient in a networked organization through a case study for A research institute, which attempted intellectual capital management domestically for the first time. The contribution of this exploratory research is to suggest new perspectives on the ownership of intangible asset, the evaluation of knowledge-based product, and the competitive advantage and complementarity of an organization in the knowledge-based economy. The limitation is that this research is just exploratory due to the inaccessibility of data. If the intellectual capital management would be more common, the diverse researches should be empirically carried out.

This study examined the effect of perceived risk, an under-explored area in the knowledge sharing literature. We proposed that employee perceptions of risk relate positively with their knowledge sharing behaviors (donating and collecting), and examined the mediating role of impression management strategies in the hypothesized relationships. We also explored the moderating effect of leader-member exchange (LMX) in the relationship between perceived risk and impression management strategies. Valid and reliable self-report and supervisory evaluation measures were collected from a sample of 251 railroad employees in safety-sensitive positions. The results indicate that perceived risk was not significantly associated with knowledge sharing, but rather the risk perception impacts were indirect through impression management strategies such as exemplification and supplication. The study also found that LMX has no moderating effect on the perceived risk and impression management strategies. In discussing these results, we present significant insights in terms of subjective risk judgment as a potential mechanism which can encourage organizational politics.

We present a framework of an intelligent design support system for embodiment design of machine tools which can support efficiently and systematically the machine design by utilizing design knowledge such as objects(part), know-how, public, evaluation, and procedures. The design knowledge of machining center has been accumulated through interview with design experts of machine tool companies. The processes of embodiment design of machining center are established. We also introduce a hybrid knowledge representation so that the systm can easily deal with various and complicated design knowledge. The intelligent design system is being developed on the basis of object-oriented programming, and all parts of a design object, machining center, are also classified by the object-oriented modeling. For the demonstration of effectiveness of the suggested system, a structural design system for machine tools is implemented.

This study examined the children's knowledge and behaviors towards food safety and hygiene. The data were collected from 521 elementary school students in Youngnam region by the self-administered questionnaires. Frequencies and analysis of variance (ANOVA) were conducted by SPSS WINDOWS. The results of the survey were as follows: first, the knowledge level of child towards food safety and hygiene was not that high. Additionally, behavior level was various according to the category of food safety and hygiene. Second, the knowledge and behavior levels for food safety and hygiene were high proportionated to the interest levels for them. Third, there were significant relationships between the knowledge and the behaviors for food safety and hygiene. These results suggest that the education for food safety and hygiene should be performed for the elementary school students to improve the levels of knowledge and behaviors of them.

Now, there are prodigiously expanding worldwide economic networks in the information society, which require their social structural changes through technology innovations. This paper so tries to formally define a process-centered knowledge model to be used to analyze policy-making procedures on technology innovations. The eventual goal of the proposed knowledge model is to apply itself to analyze a topic network based upon composite keywords from a document written in a natural language format during the technology innovation procedures. Knowledge model is created to topic network that compositing driven keyword through text mining from natural language in document. And we show that the way of analyzing knowledge model and automatically generating feature keyword and relation properties into topic networks.

The purpose of the study was to examine job satisfaction, work performance, work satisfaction, perceived needs and self-evaluation of knowledge and skills of nutrition teachers. Survey questionnaire was administered to 106 nutrition teachers in schools of Gyeonggi area. Subjects were categorized into high- or low-job satisfaction group, and study variables were examined by job satisfaction group. Overall job satisfaction was high, with a mean score of 14.9 out of 20. High-job satisfaction group had more favorable perception regarding human relations and workplace atmosphere compared to the counterparts (p < 0.001). Work performance, examined by 12 items, was not significantly different between the two groups. However, satisfaction regarding specific work of nutrition teachers was significantly different by job satisfaction (p < 0.001). High-job satisfaction group responded that they had more knowledge and skills in areas such as food purchase management, food sanitation and safety management, equipment and facility management, nutrition education, nutrition counseling (p < 0.01), and general management & marketing (p < 0.05). High-job satisfaction group also indicated that nutrition teachers need to have more knowledge and skills than the counterparts, regarding food purchase management (p < 0.001), nutrition education (p < 0.01), nutrition counseling, general management and marketing, and teaching practices (p < 0.05). In addition, study results showed significant positive correlations among study variables. This study suggested that job satisfaction of nutrition teachers might be increased by having favorable human relations and workplace atmosphere, increasing satisfaction with specific work of nutrition teachers, and by increasing the knowledge and skills required for the work of nutrition teachers.

Objectives: The study was conducted with the aim of evaluating applied occupational health teaching for final-year medical students at Hacettepe University, Faculty of Medicine. Methods: The study included all sixth grade medical students (n=293) during one academic year. Pre- and post-training tests were used to assess the magnitude of change in knowledge and attitude of students on occupational health, whereas the opinion of students on several aspects of the quality of teaching sessions were assessed by using post-training questionnaires. Results: Post-training tests revealed that the level of knowledge on all aspects of occupational health increased among medical students. An evaluation of the teaching sessions showed favorable results for the overall quality of the sessions: 81.3% of the students stated that the sessions were well organized, 81.7% remarked the workplace/factory visit was a valuable experience, and 91.0% stated feeling more competent on occupational health issues. Conclusion: There was a greater increase in students' knowledge on technical precautions than their knowledge on issues related to medical practice in the workplace. Visiting a workplace was found to contribute to the overall aim of knowledge and attitude change on occupational health issues. The scope of undergraduate medical education should be extended by improving occupational health education with respect to educational content, duration, and methods.

The purpose of this thesis is to study on the philosophical analysis model and its methodological application of information systems research evaluation from critical realist perspective. Fist of all, I examine ontological epistemological methodological assertions of critical realism. Because the philosophy of critical realism is an opportunity for information systems study. I examine Dobson and Mutch's critical realist perspective on actors-structure model. I suggest a critical realist actors-praxis-structure model. This model provides the potential for a new approach to social investigations in its provision of an ontology for the analytical separation of structure and agency. Of most importance might be the incorporation of non-humans into the analysis of social interaction and of technology into the elaboration of structures. I also examine Tsoukas's critical realistic meta-theory of management. I suggest a critical realist IS management model. This model elucidate the nature of management and delineate the scope of applicability of various perspectives on management. The causal powers of management reside in the real domain and, taken together, their logics are contradictory, the effects of their contradictory composition are contingent upon prevailing contingencies. I analyze Carlsson's theory of design knowledge. His framework builds on that the aim of IS design science research is to develop practical knowledge for the design and realization of different classes of IS initiatives, where IS are viewed as socio-technical systems and not just IT artefacts. The framework proposes that the output of IS design science research is practical IS design knowledge in the form of field-tested and grounded technological rules. The IS design knowledge is developed through an IS design science research cycle. In conclusion, I think that IS actors-praxis-structure model, meta-theoretical IS management model, and IS design knowledge model according to critical realistic approach are very useful for IS research evaluation. Nevertheless, important problems are left not resolved.

This study is to establish the domains and the standards of instructional evaluation on the teacher knowledge dealing with the knowledge of 'teaching and learning methods and assessment'. Especially, in this study, the instruction assessment standards are developed focused on the six types of mathematics competencies such as problem solving, communication, reasoning, creativity and collaboration, information and handling, attitude and practice which were emphasized in the mathematical curriculum revised in 2015. By the result, seventh evaluation domains such as an instruction involving problem-solving activity, an instruction involving reasoning activity, instruction involving communication activity, instruction on information and handling activity, instruction involving learners' achievement level and attitude, instruction involving the development of assessment method and tool, instruction applying on assessment result were new established. According to those domains, the 19 instructional evaluation standards were developed totally. This study is limited to consider the domain of 'teaching and learning methods and assessment' among the domains of teacher knowledge, while dealing with the elements of mathematics competencies in the standards. However, instructional evaluation standards reflecting these competencies should be developed in the other diverse domains of teacher knowledge.
