A knowledge-based system with CAD is widely used to implement a designer's know-how and a routine calculation within a system. An engineer needs to change several design parameters in an early design stage. However it is not easy to change the design parameters when it needs to update an existing model and data. In this paper, a module has been proposed to make it easy to change the design parameter so that the engineer can easily update and change the design model. Also a flexible interface of the module can easily add or extract the design knowledge.

This research presents distributed database and knowledge-base modeling approach for intelligent product design system. The product design information in this study is described by a collection of rules and design knowledge that are utilized according to the product development procedures. In this work, a network-based architecture has been developed to enable dispersed designers to simultaneously accomplish remote design tasks. A client/server communication diagram has also been proposed to facilitate consistent primary information modeling for multi-user access and reuse of designed results. An intelligent product design system has been studied with the concepts of distributed database and network-based architecture in order to support concurrent engineering design and automatic design part assembly. The system provides the capability of composing new designs from proper design elements stored in the database and knowledge-base. The distributed intelligent product design is applied to the design of an automobile part as an example.

Most of the existing studies on intellectual capital have focused on categorizing and measuring intellectual capital. In this study, the components of intellectual capital have been termed individual capital, organization capital, and relation capital, and the relations among these components as well their effects on other components have been examined. Thus, the indices of intellectual capital have been measured, hypotheses formed, and data collected from 62 knowledge-based companies. The results confirm some of the hypotheses. In all the companies that replied, individual capital was positively related to organization capital and organization capital was positively related to relation capital. The hypothesis that relation capital is positively related to performance, therefore, could be accepted. In the knowledge-based companies, the results were similar to the previous ones, but individual capital was not related to relation capital.

This study assessed knowledge-based environments for knowledge management in hospital dietetic departments. This study categorized the current knowledge management environment into routine habits, capability, culture and system. A questionnaire was conducted on dieticians in general hospitals with 400 beds in Seoul and Gyeong-in areas. Excluding responses with significant missing data, 160 usable questionnaires were analyzed by SPSS package programs for the study. The result of the study is summarized as follows. The average number of licensed beds in the hospitals was 717.5 and the average number of meals provided daily was 1,626.3. 53.2% of dieticians were aged between 26 and 35. Of the maximum score of 5 points, habits scored $3.65{\pm}.44$ points, capability scored $3.38{\pm}.44$ points, culture scored $3.21{\pm}.46$ points and system scored $2.77{\pm}.74$ points. Hospitals with a high ratio of occupied beds also had significantly higher points in capability, culture and system. The older the group the higher points it scored in habits and culture. The married group scored higher points in habits while the higher educated group scored higher points in habits and capability. The dietitians in charge of clinical nutrition scored higher points in habit, capability and culture while the higher salaried group scored higher points in habit, culture and capability. Therefore this study would provide useful information for the introduction of knowledge management in hospital dietetic departments.

In this research, we tried to suggest the guidelines to stakeholder of ICT startup for picking up the excellent startups and nurturing them. We designed the research model focused on the good startup team's knowledge based interaction mechanism. A research model and hypotheses were developed from literature review and empirically validated. The research model consisted relationship among the knowledge sharing (knowledge donation and knowledge collection), absorptive capacity (member's ability and member's motivation), team creativity, and innovation capability. Data were collected from ICT Service Startups, and a partial least squares (PLS) analysis was made on 175 data points. The analysis results showed that absorptive capacity has significant effect on team creativity and innovation capability directly. And also it has indirect effect on the dependent variable through team creativity. On the contrary, knowledge sharing does not have statistically significant effect on team creativity and innovation capability; only have an effect on absorptive capacity. Based on the results, we proposed several team management skills for ICT startup leaders and members, and the guidelines to stakeholder such as government and private investors. Also there are some ideas for startup nurturing polices for government officers. Theoretical contributions are discussed at the end with limitations and further studies.

Purpose: Knowledge, clinical reasoning, and self-confidence are the basis for undergraduate education, and determine students' level of competence. The purpose of this study was to assess the effects of the addition of a one-time simulation experience to the didactic curriculum on nursing students' knowledge acquisition, clinical reasoning skill, and self-confidence. Methods: Using a quasi-experimental crossover design consisted of intervention and wait-list control groups. Participants were non-randomly assigned to the first intervention group (Group A, n=48) or the wait-list control group (Group B, n=46). Knowledge level was assessed through a multiple choice written test, and clinical reasoning skill was measured using a nursing process model-based rubric. Self-confidence was measured using a self-reported questionnaire. Results: Results indicated that students in the simulation group scored significantly higher on clinical reasoning skill and related knowledge than those in the didactic lecture group; no difference was found for self-confidence. Conclusion: Findings suggest that undergraduate nursing education requires a simulation-based curriculum for clinical reasoning development and knowledge acquisition.

Purpose: This study proposes a model for future research agendas on knowledge management activities as a source of increasing sustainable competitive advantage. Based on the literature, the role of knowledge management in sustainable competitive advantage does not necessarily have a significant effect but involves other variables. For this reason, future research proposals on the role of knowledge management on sustainable competitive advantage and other relevant variables need to be carried out. Research design, data, and methodology: This research uses a literature study. The model development stage is (1) relevant research studies, (2) identification of relevant theories and related variables, (3) developing and making a hypothesis (4) proposed model. Results: From the literature study, it was found that knowledge management plays a role in increasing managerial competence, market orientation, and innovation. Furthermore, managerial competence, market orientation, and innovation significantly affect sustainable competitive advantage. However, other studies have found a different relationship. Conclusions: This study proposes a research model on the role of knowledge management, managerial competence, market orientation, and innovation to improve sustainable competitive advantage. The study results can be used for further research based on the proposed model and as a reference for company owners and management to increase competitive advantage.

This study divided pre-service elementary school teachers' knowledge conversion into four types, socialization, externalization, combination and internalization, based on their inquiry activities on the life cycle of cabbage butterfly. As research subjects, this study collected results from 24 pre-service elementary school teachers who carried out inquires on the life cycle of cabbage butterfly for about 2 months. The type of socialization indicates the conversion of tacit knowledge into tacit knowledge, and this study found out that pre-service elementary school teachers acquired and accumulated tacit knowledge from their fellow pre-service teachers, professors and even acquaintances inside and outside the lab. However, there appeared no process that they shared their tacit knowledge with other pre-service teachers or delivered it to them. The type of externalization indicates the conversion of tacit knowledge into explicit knowledge, and this study discovered some cases that pre-service elementary school teachers expressed their inner tacit knowledge into explicit knowledge. However, there was no case found that they converted the verbally-unexpressed tacit knowledge of their fellow teachers or experts into well-defined explicit knowledge. The type of combination indicates the conversion of explicit knowledge into explicit knowledge, and this study discovered some cases that they collected explicit knowledge and converted it into new explicit knowledge for the acquisition, integration and delivery or distribution of explicit knowledge. However, there were few cases that they creatively devised new explicit knowledge by acquiring new knowledge through direct observation and supplementing the existing explicit knowledge. The type of internalization indicates the conversion of explicit knowledge into tacit knowledge, and this study discovered both explicit knowledge embodied through personal experiences and explicit knowledge embodied through simulations and experiments that formed tacit knowledge in process of examining the existing explicit knowledge.

In this article we study a reconstruction of mathematical knowledge on trigonometry by the method of ascent from the abstract to the concrete from the pedagogical viewpoint of dialectic. The direction of education is shifting in a way that emphasizes the active constitution of knowledge by the learning subjects from the perspective that knowledge is transferred from the teacher to the student. In mathematics education, active discussions on the construction of mathematical knowledge by learners have been going on since the late 1990s. In Korea, concepts and aspects of constructivism such as operational constructivism, radical constructivism, and social constructivism were introduced. However, examples of practical construction according to the direction of construction of mathematical knowledge are very hard to find. In this study, we discuss the direction of the actual construction of mathematical knowledge and suggest a concrete example of the actual construction of trigonometry knowledge from a constructivist point of view. In particular, we discuss the process of the construction of theoretical knowledge, the ascent from the abstract to the concrete, based on the literature study from the pedagogical viewpoint of dialectic, and show how to construct the mathematical knowledge on trigonometry by the method of ascent from the abstract to the concrete. Through this study, it is expected to introduce the new direction and new method of knowledge construction as 'the ascent from the abstract to the concrete', and to present the possibility of applying dialectic concepts to mathematics education.
