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.

오늘날 지식관리시스템은 효과적으로 지식 프로세스를 지원하고. 다양한 비정형의 지식들을 처리하기 위한 다양한 시도들을 하고 있다. 그러나 지식 검색, 정보 추출, 관리 등에서 근본적인 약점을 갖고 있으며, 다양한 지식 자원들을 통합하고 연동하는데 어려움을 갖고 있다. 이런 한계들을 극복하고 지식관리 방식을 개선하기 위한 다양한 연구들이 시도되고 있다. 본 논문에서는 최근 주목받고 있는 시맨틱 웹 기술을 적용함으로써 지식관리시스템들이 직면한 한계들을 극복할 수 있는지, 그리고 어떤 장점과 기회들을 얻을 수 있는지 고찰하였다. 그리고 기존 지식관리시스템 아키텍처와 비교하여 변경되는 부분들을 살폈으며. 새로운 시맨틱 지식관리시스템 아키텍처와 향후 전망, 그리고 나아갈 바를 제시하고자 하였다.

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).

본 연구의 목적은 과학 교과교육학 지식의 본질과 역할이 무엇이며 어떻게 발달하는가를 알아보는데 있다. 구체적인 연구 문제는 첫째, 과학 교과교육학 지식의 본질과 구성 요소는 무엇인가? 둘째, 과학 교과교육학 지식의 가치와 교사의 과학 교과교육학 지식은 어떻게 발달하는가? 이다. 이를 해결하기 위해서 본 연구는 실증적이고 경험적인 데이터에 의한 문제해결보다는 문헌 연구를 통한 접근을 하였다. 연구 결과는 다음과 같다. 과학 교과교육학 지식의 본질은 첫째, 교사 개인이 특정한 과학 수업 상황 속에서 과학 교과를 가르치는데 사용하는 과학의 내용 지식과 과학 교수방법 지식의 합성체를 의미하는 것이다. 둘째, 교사 자신이 가지고 있는 교수를 위한 독특한 지식체로서 과학 교사 전문성의 요체가 되며, 자질 있는 과학 교사가 갖추어야 할 가장 핵심적이고 필수적인 사항이다. 셋째, 어떤 특수한 상황에서 특수한 내용을 어떻게 가르치느냐에 관한 지식으로서 이것은 각 교사마다 독특하게 구성된 지식 체계에 따라 달라진다. 과학 교과교육학 지식의 구성 요소는 과학 교수에 대한 지향, 과학 교육과정에 대한 지식과 신념, 특수한 과학 주제에 대한 학생들의 이해에 관한 지식과 신념, 과학에서 평가에 관한 지식과 신념, 과학 교수를 위한 수업전략에 관한지식과 신념이다. 과학 교과교육학 지식의 발달은 교과 내용에 대한 개념적 지식이 충분히 형성되어야 하며, 이 내용 지식을 실제적인 교수 경험을 통하여 반복적으로 사용함으로써 발달한다.

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.
