In this study, we propose an efficient expert system (ES) construction mechanism by using dynamic knowledge map (DKM) and database management systems (DBMS). Generally, traditional ES and ES developing tools has some limitations such as, 1) a lot of time to extend the knowledge base (KB), 2) too difficult to change the inference path, 3) inflexible use of inference functions and operators. First, to overcome these limitations, we use DKM in extracting the complex relationships and causal rules from human expert and other knowledge resources. Then, elation database (RDB) and its management systems will help to transform the relationships from diagram to relational table. Therefore, our mechanism can help the ES or KBS (Knowledge-Based Systems) developers in several ways efficiently. In the experiment section, we used medical data to show the efficiency of our mechanism. Experimental results with various disease show that the mechanism is superior in terms of extension ability and flexible inference.

This society is rapidly changing into an information-oriented society. As such, revolutionary and efficient teaching methods are needed in school education rather than traditional methods. To be an efficient teaching lesson, teaching plans based on learners' prior knowledge are needed. The knowledge-space theory provides the methods of efficient analysis about learners' status of knowledge. This study designs and implements the support-learning tool based on the knowledge-space theory to increase the efficiency in classroom lessons through the development of various methods of analysis of learners' knowledge status.

The purpose of this study was to investigate the differences of clothing majors and non-majors in clothing knowledge and consumption behavior. Subjective and objective knowledge were compared and factors of clothing consumption behavior were analyzed across the two groups. The subjects of this study were female student who went to University in Seoul. Data from 150 college female students were analyzed using SPSS. Results indicated that clothing majors had significantly higher level of clothing knowledge. The differences were smaller for subjective knowledge levels than objective knowledge levels. Clothing majors tended to reform their clothes and coordinate their clothing items better than non-majors. They considered styles more importantly than brands but have some level of conformity. Among clothing consumption behavior factors, reform ability and coordination ability significantly affected clothing knowledge.

Existing CAD systems have configured geometry data and it is necessary to extend the configured geometry into a knowledge-based system. An intelligent CAD system emerged to provide such a knowledge-based system. However the intelligent CAD system has a limited product model to represent various knowledge models. This paper presents a model, called extended intelligent CAD model, which can extend the product model of the intelligent CAD system into further detailed knowledge model. The extended intelligent CAD model includes a whole design process knowledge and an efficiency of the model has been verified via a knowledge based wiper design system. The model can improve the functionality and efficiency of the existing CAD systems.

The management of enterprise knowledge has been increasingly important because knowledge emerges as the new basis of competition in postcapitalist society. One of the key issues in knowledge management is to put knowledge into a repository where it can be easily stored, reused, and recreated. This paper proposes a model repository and the corresponding knowledge management framework. The emphases of model repository is on abstraction knowledge in the form of schematic models. Two major benefits are model independence and model integration. A metaschema is constructed according to six conceptual components: separate unit, external link, internal link, separate unite descriptor, link descriptor, and composite descriptor, which can be applied for a variety of models. A prototype system with a case illustrates the practical usefulness of model repository for knowledge management.

The purpose of this study was to evaluate the effects of CPR education programs on seafarers and the retention period of the knowledge. The subjects of this study were 40 seafarers who took safety training courses at the Korea Institute of Maritime and Fisheries Technology. The seafarers were tested for their knowledge and attitude before, immediately after, 1 month after, and 3 months after the CPR education program. Data were analyzed for frequency, percentage, ${\chi}^2-test$, and t-test, and ANOVA was measured repeatedly using an SPSS statistical program. Knowledge, attitude, and performance ability were significantly increased post-education as compared to pre-education. Knowledge, attitude and performance ability were consistent when tested after 1 month, but knowledge, attitude, and performance ability were significantly decreased when tested three months later. Therefore, to maintain knowledge, attitude, and skills in performing CPR, appropriate renewal times are necessary in regular seafarers' safety training centers and sailing vessels.

In recent years, organizations have chosen a team-organization as a standard activity level and it leads a significant change in process of knowledge producing. Nevertheless team-organization for building up effective performance and a good communication in organization has influenced knowledge management performance, the empirical analysis and survey have not proved yet. This study, therefore, makes an analysis that the change of organization base on team activity influences knowledge management performance. This study, based on 312 data by using LISREL as a model for studying, provides a result that a team-based activity positively influences knowledge management efficiency.

There are so many researches about the search method for the most compatible dispatching rule to a manufacturing system state. Most of researches select the dispatching rule using simulation results. This paper touches upon two research topics: the clustering method for manufacturing system states using simulation, and the search method for the most compatible dispatching rule to a manufacturing system state. The manufacturing system state variables are given to ART II neural network as input. The ART II neural network is trained to cluster the system state. After being trained, the ART II neural network classifies any system state as one state of some clustered states. The simulation results using clustered system state information and those of various dispatching rules are compared and the most compatible dispatching rule to the system state is defined. Finally there are made two knowledge bases. The simulation experiments are given to compare the proposed methods with other scheduling methods. The result shows the superiority of the proposed knowledge base.

Objectives: This research has been conducted in order to conduct sex education using E-Learning which is currently taught to students of women's high school. 138 students at women's high school in Inchon were applied, and then they were divided two different groups: a comparison group of 69 students, a control group of 69 students. Method: A questionnaire used by the literature studies. After verifying content validity, it was modified and supplemented in this way: sex knowledge was 23, and sex attitude 25. Results: 1) Comparison group will show increased marks on sex knowledge after the education than before whereas those from control group. 2) Comparison group will show increased marks on sex attitude after the education than before whereas those from control group. Conclusion: From the results of this research, it can be said that the sex education using E-Learning was the most effective method in improving the sex knowledge and attitude of students at women's high school. Therefore, it is advisable that the sex education methods using E-Learning should be developed and applied continuously.

Purpose: This study was conducted to investigate how a program using video-audio media will affect the knowledge level and compliance of the sick role of patients admitted for coronary angiography. Method: A non-equivalent control group non-synchronized design was used. Subjects were selected from patients admitted to the internal ward of a hospital in B city for coronary angiography between July 1 and September 31, 2010. Twenty subjects were assigned to the control and experimental group, respectively. Video-audio media developed by the authors was used as the experimental tool. The effects of the program were analyzed using a knowledge assessment tool and questionnaire for compliance of the sick role. The SPSS/WIN 14.0 program was used for data analysis. Result: The first hypothesis that the "experimental group receiving the program using video-audio media will report a higher level of knowledge compared to the control group" was supported. The second hypothesis that the "experimental group that received the program using video-audio media will report a higher level of compliance of sick role" was supported. Conclusion: The program using video-audio media was effective in enhancing patients' knowledge about the disease and compliance of the sick role. Thus, it can be an effective nursing intervention for patients with coronary artery disease.
