In this paper, we consider two-species periodic Gilpin-Ayala competition system with delay and impulsive effect. By using some analysis methods, sufficient conditions for the permanence of the system are derived. Further, we give the conditions of the existence and global asymptotic stable of positive periodic solution.

사서교사와 학부모의 협력 관계는 학교도서관의 학습 공동체적 성격과 경영의 확대 측면에서 매우 중요한 경영 요소이다. 이러한 협력 관계는 학생의 스트레스와 위험요소를 완화함으로써 학생의 자아 탄력성을 활성화하는데 기여한다. 본 연구에서는 10명의 현직 사서교사를 대상으로 학부모와의 협력 관계를 통한 학생지도 사례를 분석하고, 관계 형성에 어떠한 공식 또는 비공식 커뮤니케이션 채널을 활용하고 있는지 알아보았다. 분석 결과 사서교사는 학부모와의 협력이 필요하다고 인식하고 있으며, 학생의 생활지도, 진로지도, 독서상담 및 담임교사와 학부모 간의 갈등 조정 등의 경험이 있는 것으로 나타났다. 그리고 사서교사와 학부모의 공식 커뮤니케이션은 학교도서관운영위원회와 같은 제도적인 협의체 보다는 함께 참여하는 독서프로그램인 것으로 나타났다. 또한 사서교사는 학교도서관에서 이루어지는 학부모 모임이나 연수를 통해서 학부모와 비공식적으로 만나고 있다. 학부모를 위해서 학교도서관이 제공하는 정기 프로그램은 독서관련 행사와 연수이며, 주요 홍보 수단은 가정통신문과 학교홈페이지인 것으로 나타났다. 사서교사와 학부모가 협력을 통해서 학생의 자아 탄력성 강화에 기여하기 위해서는 학교도서관운영위원회에 학부모를 참여시킴으로써 공식적인 커뮤니케이션 채널을 확보해야 한다. 그리고 학부모의 도서관 운영 참여를 단순한 일손 돕기 보다는 책 읽어주기, 도서관 이용 안내, 사서교사의 도서관 활용수업 보조, 교수매체 제작 등으로 확대하는 것이 바람직하다.

본 연구는 중 고등학교 과학교사의 탐구수업 환경 요인에 대한 인식을 조사하였다. 조사도구는 근무 여건, 탐구수업 환경 요인, 탐구수업 장애 및 개선 요인 등의 3개 영역으로 구성되어 있다. 중 고등학교 과학교사간의 근무 여건에는 유의한 차이가 없었다. 탐구수업 환경 요인에는 '시설 및 장학지원', '업무량과 학습자료', '교사교육과 교과서', '탐구에 대한 지식과 실천', '필요성 인식과 교사의 만족도' 등 5개의 요인으로 구성되었으며, 중 고등학교 과학교사들은 '필요성 인식과 만족도'를 제외한 나머지 요인들에 대해 탐구수업을 실시하기에 부적절한 수준인 것으로 생각하였다. 탐구수업의 장애 및 개선 요인으로 중학교 과학교사들은 '다인수 학급', '교과서', '학습 자료'를 우선으로 생각하였으며, 고등학교 과학교사들은 '다인수 학급'과 '입시제도'를 우선으로 생각하였다. 중 고등학교 과학 탐구수업을 활성화시키기 위해서는 적절한 탐구 학습자료의 개발과 보급을 통해 업무량 및 심리적 부담을 감소시키고, 교사 교육의 체계적인 재조직 및 강화가 요구된다.

The hypothesis of the study of the article is that the use of elements of artificial intelligence will increase the effectiveness of the educational process of the university if: a set of pedagogical conditions for the construction and use of an expert system with elements of artificial intelligence in the educational process of the university is revealed; a model for preparing a future teacher of vocational training for the use of elements of artificial intelligence has been developed; a special course has been developed that contributes to the implementation of the professional orientation of education. In accordance with this, the following tasks were studied in the article: An analysis of scientific and methodological research in the field of the current state, prospects for the development and use of elements of artificial intelligence in the preparation of a future teacher of vocational training and to determine the dynamics of the introduction of intelligent expert systems in education; A set of pedagogical conditions for the construction and use of an expert system with elements of artificial intelligence in the educational process of a university is revealed; It is substantiated to develop a model for preparing a teacher of vocational training to use elements of artificial intelligence.

In this work, transient heat transfer analysis of functionally graded (FG) carbon nanotube reinforced nanocomposite (CNTRC) cylinders with various essential and natural boundary conditions is investigated by a mesh-free method. The cylinders are subjected to thermal flux, convection environments and constant temperature faces. The material properties of the nanocomposite are estimated by an extended micro mechanical model in volume fraction form. The distribution of carbon nanotube (CNT) has a linear variation along the radial direction of axisymmetric cylinder. In the mesh-free analysis, moving least squares shape functions are used for approximation of temperature field in the weak form of heat transform equation and the transformation method is used for the imposition of essential boundary conditions. Newmark method is applied for solution time depended problem. The effects of CNT distribution pattern and volume fraction, cylinder thickness and boundary conditions are investigated on the transient temperature field of the nanocomposite cylinders.

Elementary education in Korea has variously changed and developed during the last thirty years. Among all the progressive changes, the improvement of teaching conditions is considered to be the most fundamental one. The number of students assigned to a class or a teacher has decreased to a considerable extent. Cyber teaching-learning has been peformed at school and home, and English education has been emerged as a significant part of the Korean public education. The research issues constantly considered essential over the past three decades starting in the 1980's are those related to curricula, teaching-learning methods, training of teachers in-service, and education for upright characters. The practical and political issues should be dealt with to revise the three integrated subjects and text books into a sole integrated subject and text book, to double the credential of teachers in terms of professionalism and to decrease the number of students per teacher in Korea to the OECD level.

In their teaching practice, teachers encounter multi-dimensions of pedagogical challenges. The recognition and reflection on these challenges is crucial to advance our science teaching. This study looked into science teachers' dilemmas of their teaching practical work through their written cases. Dilemma cases are teachers' narratives organized around important events of teaching and learning. It can reveal teachers' situated cognition and be used as lens to investigate complex realities of science teaching and learning. 26 pre- and in-service elementary teachers' dilemma cases of science practical work were carefully collected and analysed to interpret what constitute tensions in elementary science practical works. They were largely grouped into three: Curriculum and Institutional Relevance, Students Relevance, Nature of School Experiments Relevance and divided into 7 subheadings: 'Authority of Curriculum(textbook)', 'Disappointment at external support', 'Students' interests and safety', 'Students' unscientific and inert attitude', 'Difficulty of showing expected results', 'Generalization through experiment', 'Knowledge acquisition and authentic inquiry'. Each dilemma was interpreted in terms of the tensions which constitute contradictory beliefs, values, expectation and realities. These dilemmas enabled to expose actual conditions of elementary science practical work and teachers' challenges otherwise can not be seen easily. Science teacher educators also can get some implications to overcome the gap between theory and practice in their teacher education.

This article tried to show a new paradigm for elementary school counseling in Korea. Counseling in Korean elementary school has focused on the individual child and/or group of the children without considering school circumstances. But school has some special features which have to be counted for the efficiency of child counseling. Take for an example, children have to spend most of their day time with a class teacher for 6 days a week. So the talks and behaviors of the class teacher have strong influence on the children. These factors should be included in the elementary school counseling to help children grow up and develop. : Six main topics discussed in this articles were as follows. 1. Developmental tasks of Korean children have to be searched and organized. 2. The concept of class management has to be combined with the concept of counseling. 3. Establishing the conditions to facilitate subject learning has to be emphasized in the school counseling. 4. Counseling instruments applicable to the children should be developed. 5. The proper knowledge of teacher's way cf talking and behaving in class life should be organized. 6. The resources of school counseling should be identified and interconnected to provide better counseling service to the children.

This study is mainly concerned with researching the perception and the actual conditions of the body education in the kindergarten. For the purpose of this study, the research was carried out using 150 early childhood teachers located in Pusan. Data were collected from survey and interview with early childhood teachers June 2014 to March 2015. Interview proceeded total 5 sessions by study participant and that was required about 1 hours. Questionnaire extracts basis category that analyzes literatures and researches related to body systematically and arranged question category and contents according to investigator's study objective. The results of the study were, first, There is need for deterritorialization and reterritorialization in perception of the teachers of the children's body. second, we need learning and teaching based on children body in teaching and learning activities. It begins with perception change of teacher. And these activity in the classroom are required accordingly. Third, the method for reducing the gap between teacher's perception of body and teaching activities have to be provided.
