We investigated the conceptual and methodological characteristics of self-study as an innovational way with reflective research methods and explored the possibility of application of self-study in the field of science education by reviewing previous researches done in foreign countries. The results show that Self-study in education means the study of self, self-practice, self-thought, and so on in the teaching and learning context. It is a kind of new research method to pursue the improvement of teaching and learning practice with integrated perspectives on the context of instruction, identities of members, their beliefs and values, innovation agenda for better education, etc. This can be attained by collective and critical reflection in doing research. Most previous articles on the methodology of self-study suggested that the self-study should be more than just daily journals written only by her/him self. To do self-study in the academic way, they requested interaction with critical and cooperative colleagues, multiple but strict qualitative research methods, and participants' efforts for making better practice in instruction. Similar features to the above are found in the previous 14 self-study papers related to science education done in foreign countries. Based on the results, we concluded that self-study could be applied usefully into the field of science education in Korea. This paper could contribute to stimulation in the innovation of science instruction in a more practical way by increasing the attention to self-study and provoking its practice in Korea.

The purpose of this study is to analyze the research articles on social work practice and discuss tasks of social work practice research in broadening and deepening social welfare knowledge body in Korea. First, this paper arranges critical discussion and results on social work practice research since the dawn of history in Korean social welfare research. Second, this paper examines 874 research articles published in Korean Journal of Social Welfare from the volume one in 1998 to the volume 66(4) in 2014. The appearance rate of social work practice research was 16.6%(145 articles), and empirical research in relation to social work practice was 40.5%(363 articles). Among 145 articles, 8.6% were practitioners, and the rest of them were in the position of professors. In addition, 26.2% were researches on program effectiveness, and 29.0% were researches on social worker. Third, this paper was interviewed 8 professors who majored social work practice. They evaluate the present states of social work practice research as positioning to boundary, crisis and confusion. Finally, this paper discusses the tasks of Korean social work practice research in order to more solidly develop the knowledge body of social work practice in Korea.

정보화시대에 요구하는 인재는 문제를 인식하고 이런 문제를 풀기 위해 다양한 전문가들과 함께 창의적인 사고를 통해 해결책을 제시하는 인물이다. 정보영재교육의 목표 역시 창의적 인재를 기르는 데 있으나, 프로그래밍과 알고리즘 교육은 특정 프로그래밍 언어의 사용법이나 문법 위주의 교육, 정렬 및 탐색과 같은 알고리즘 그 자체에 치중함으로서 이러한 목표에 도달하고 있지 못하다는 지적이 많다. 이에 본 논문에서는 창의적인 알고리즘을 설계하고 개발하는데 필요한 사고력, 즉 사고 과정에 대해 안내하고 생각하는 알고리즘적 사고력을 기르기 위한 방안으로 실생활 주제의 이야기 쓰기를 활용하는 교수 학습 프로그램을 제안하였다. 반성적 사고와 창의성을 기르는 데 효과적인 것으로 알려진 이야기 쓰기 활동에서 출발하여 사건 요소 추출과 시간적 질서 분석하기, 순서도로 알고리즘 표현하기, 동료 학습자와 토의하기 등의 과정을 통해 알고리즘적 사고력을 향상시킬 수 있도록 하였다.

The purposes of this study are to examine what the participants experienced when developing Content Representation (CoRe) of "molecular motion" for the 7th grade in collaboration with experienced chemistry-trained teacher and non-chemistry-trained teacher and to investigate how the participants' PCK changed in their classes after developing CoRe. The participants were one experienced chemistry-trained teacher, two physics-trained teachers, and one researcher. The participants were selected by purposeful sampling. For this study, the discussions on developing CoRe was recorded and two physics-trained participants' classes were video-taped, and constructed/semiconstructed interviews were conducted. All data were transcribed for analysis. The participants experienced reflective thinking of their knowledge and previous classes, corrected their own misconception and clarified those conception, recognized the contents and the goals of "molecular motion" class, enhanced understanding of students' preconception during the development of CoRe. Especially, the two physics-trained teacher-participants confessed that they recognized clearly the contents and the goals of "molecular motion" class and identified their deficiency in 'particle viewpoint' in their previous classes. Their recognition was realized in the course of interaction with experienced chemistry-trained teacher. Among the components of PCK, knowledge of science curriculum was most influent on two physics-trained teacher-participants' classes, and they emphasized 'particle viewpoint' and 'molecular motion' in their classes. In addition, they introduced new teaching strategies that were discussed in the course of developing CoRe. The influence on the participants' PCK was different according to their reflective thinking on their own knowledge and previous classes and their affective characteristic. The implication of this study is that, the course of developing CoRe can promote reflective thinking that is essential for increasing teachers' professionalism and significantly influence on PCK. Especially, developing CoRe in collaboration with experienced chemistry-trained teacher and non-chemistry-trained teacher can identify deficiency in their classes and thereby, improve their classes. And, it takes time and effort to internalize the participant's recognition in their teaching practice.

지금까지 우리는 배합사료 가격의 생산비가 왜 높은지 더 절감할 수 있는 방법이 있는지 없는지에 대한 원인 분서과 대책은 생략되어 왔다. 이제 사료 문제를 근본적으로 개선하지 않고는 다 함께 익사할 수 밖에 없도록 국제 환경이 변화하고 있다. 우리는 사료산업의 문제를 사료가격 인상이라는 몰핀 투약으로 처리해 온것이 아닌지 반성해야 하며, 정부는 자가배합 등 양축가들이 경쟁할 수 있는 조건을 만들어 줘야 한다.

A model of STS (Science-Technology-Society) creativity education program for the gifted and talented children has been developed, based on GENEPLORE thinking process and Knowledge development theory. The GENEPLORE creative thinking process, developed by Finke et al. (1990, 1992), has two phases such as generative phase and exploratory phase. And The knowledge development theories of Piaget (1977) and Gallagher(1981) assume that knowledge-bases are developed on the basis of empirical as well as reflective abstraction, which could imply that knowledge-bases are crucial in creative thinking process. The creativity education model for the gifted and talented of the present study attempted to integrate 'the individual, creative thinking process, and social/scientific technology' by employing topics of the science-technology-society such as computer, network, biotech, robot, e-business, e-education, e-health, nanotech and entertainment and the structure and contents of the program are proposed

Local Feature Analysis(LFA)는 눈, 코, 턱 그리고 볼과 같은 얼굴의 지역적 특징을 잘 추출하는 것으로 알려져 있으나, 얼굴 인식에 이용하기에는 몇 가지 문제점이 있다. 본 논문에서는 LFA의 문제점을 개선하여 인식에 적합한 새로운 얼굴 특징 추출 방법을 제안한다. 제안 방법은 kernel 생성, 선택 그리고 중첩의 3 단계로 이루어진다. 첫 번째 단계에서 얼굴의 지역적 특징을 검출할 수 있는 kernel물 생성하고, 두 번째 단계에서 인식에 적합한 kernel을 선택한다. 마지막으로 선택된 kernel을 중첩시켜 적은 개수의 조밀한 형태의 kernel로 재 표현한다. 실험을 통하여 제안 방법이 적은 개수의 특징을 이용하여 좋은 인식율을 보임을 확인하였다.

This study, in the view of the particulars on mathematics, tried to criticize the way how they have reformed mathematics curriculums, which moreover have been executed without any official investigation of the ways up to the recent curriculum. On the basis of these critics, this study suggested a few desirable ideas about how to reform the mathematics curriculum which were investigated from a mathematics educational standpoint. For this purpose this study was executed as followings : first, there has been reflective investigations about the existing ways of reforming mathematics curriculums ; second, there suggested a new way of reforming the mathematics curriculum which we may consider as the way for the future mathematics curriculum reform.

This study aims to describe, explain, and understand the process of coteaching instruction in which two pre-service science teachers plan, perform, and reflect the instruction in a university lecture. Pre-service science teachers exchanged their perspectives on teaching, selected the learning model and the science content to teach, and prepared the teaching material together. They performed the coteaching using the lecture room effectively and exchanging the role of leading the instruction. The professor and other pre-service science teachers participated to the coteaching instruction directly or indirectly with the role of students or lesson critics, and shared the evaluation and reflection on the instruction. We discussed the meaning and implication of the coteaching instruction on the secondary education field, the science teacher education, and the science education.
