The purpose of this research is to investigate characteristics of science content knowledge and pedagogical content knowledge shown in the primary school science classes. Through analysis of classroom teaching, explore the features and differences between primary and secondary school science PCK. Using open-ended interviews with the teachers and group discussions on a regular basis to analyze and compare classes of five primary school teachers, the relationship between CK and PCK. Regardless of the school level the teacher's PCK and professionalism is required with varying focus and emphasis. The features of the primary school teacher's PCK are as follows: Firstly, elementary teach secondary teach content, teachers value pedagogical knowledge (PK) content knowledge (CK). The primary school PCK requires more of understanding of students and teaching methods that to subject areas. PCK be without content knowledge, and the teacher's PCK is subject-specific In addition to the characteristics of PCK in the primary school science teaching, ways to set up professional exchange or collaboration between primary and secondary teachers, and to provide supplementary in-service training focused on content knowledge for primary school teachers.

There have been various attempts of Knowledge Management System in order to effectively support Knowledge Process and to manage a wide variety of unstructured knowledge. However, Knowledge Management System basically has some significant weakness for searching knowledge, extracting information and maintenance, and some difficulties to integrate such various knowledge resources. Several studies had been conducted to overcome these weaknesses and to improve the method of knowledge management. The purpose of this study is 1) to examine the effectiveness of Semantic Web Technology that has a great attention lately; whether it is useful to overcome the weaknesses, and 2) to review its strong points and some future uses. Further, differences of Semantic Web Technology compared to existing Knowledge Management System Architecture are reviewed. Finally, a new Semantic Web Enabled KMS Architecture is proposed. Also some prospects for future market direction are suggested.

As the importance of Knowledge Management System (KMS) in the military increases, Republic of Korea Army (ROK Army) developed Army Knowledge Portal. Although the members in the military are encouraged to use the portal, few members currently use it. This study was conducted to find variables to predict the user's intention to use the portal, which contributes to activating the use of Army Knowledge Portal in the army. On the basis of Technology Acceptance Model (TAM), ten variables such as perceived ease of use, general information security awareness, information security awareness, expectation for external rewards, expectation for relationships, sense of self-worth, attitude toward compliance with security policy, attitude toward knowledge sharing, intention of non-combat knowledge sharing, and intention of combat knowledge sharing were considered as independent variables. 105 participants on active duty who currently use or have experience to use the portal participated in this study. The results indicated that general information security awareness and information security awareness increases compliance with the information security policy. In addition, the attitude toward knowledge sharing is enhanced by expectations for relationship and sense of self-worth. Based on the results, the authors propose the need for policy alternatives to reinforce the reward system and security policy, which activates the use of Knowledge Portal Service for ROK Army.

The principal objective of this study was to determine the effects of mothers' nutrition knowledge on preschoolers' obesity and dietary habits. The subject population included 456 mothers and their preschoolers, aged 3 to 5 years, who were enrolling in kindergartens located in Seoul and KyongGi-Do, Korea. The results of this study are as follows: 1. The majority of mothers responded correctly to those questions concerning obesity-related nutritional knowledge, but responded incorrectly to questions regarding basic nutritional knowledge. 2. The mothers' nutritional knowledge was associated significantly with the mother's age (p<0.05) and degree of education (p<0.05). 3. The mothers' nutritional knowledge was significantly and negatively correlated with their obesity, but not with their preschoolers' obesity. 4. Mothers' nutritional knowledge was determined to be positively associated with higher interest in nutritional information and food selection in regard to weight management strategies for their kids. 5. In general, preschoolers whose mother had excellent nutrition knowledge evidenced better dietary habits than preschoolers whose mothers had poor nutrition knowledge. In particular, one question regarding serving size was significantly associated with mothers' general level of nutritional knowledge(p<0.05).

The purpose of this study is to analyze and evaluate the nature, role and development of pedagogical content knowledge in science teaching. Two research questions were considered: 1) What are the nature and the components of the pedagogical content knowledge in science teaching? 2) What is the value of pedagogical content knowledge and are there any routes and paths to developing pedagogical content knowledge for science teachers? In order to answer these questions instead of analyzing empirical data, former research literatures are reviewed. The results indicate that science pedagogical content knowledge is a special amalgam of science content knowledge and science method knowledge in a special context of science teaching that is uniquely the province of teacher based on their own special form of professional understanding. As a part of one's own distinctive bodies of knowledge, science teachers' pedagogical content knowledge is an important basis for professional development and competent teachers. It is knowledge of how to teach specific content in specific contexts, also it depends on each teachers' distinctive knowledge structure. Pedagogical content knowledge for science teaching is composed of five components: orientations toward science teaching, knowledge and beliefs about science curriculum, knowledge and beliefs about students' understanding of specific topics, knowledge and beliefs about assessment for teaching science, knowledge and beliefs about instructional strategies for teaching science. The development of science pedagogical content knowledge does not start until teachers have acquired a deeply principled conceptual knowledge of content, also it is promoted by the constant use of subject matter knowledge in teaching situations.

This study investigated elementary teachers' subject matter knowledge and pedagogical content knowledge of fractions. The subject for data collection were 12 in-service elementary teachers and data were collected through written test problems. The finding imply that most elementary teachers understand fraction construct as part-whole, show low level of understanding of operator, ratio, and measurement constructions and word problem posing, using models, and developing the algorithms to divide fractions. The research results indicates that experienced teachers possess poor knowledge of fractions against novice teachers.

The objective of this paper is to develop a knowledge assets measurement model in Korea. There are relatively many researches on measuring knowledge assets of an organization. These previous researches, however, lack of comprehensive view of knowledge management and view of Korean organizational culture. We surveyed and analyzed previous researches, and found common factors to measure knowledge assets. We developed an updated version of knowledge assets index. The developed model has been validated for its fitness with real data of Korean companies. The result of this research can be used as a measurement tool for knowledge assets of public institutions as well as private companies.
