The purpose of this research was to analyze the concept map of kindergarten teachers concerning their levels of contents knowledge and their overall level of competency in terms of multi-cultural education. The participants were 104 teachers from 11 kindergartens in Busan. Data were analyzed by Sim's (2008) method based on Novak & Gowin (1984) and Morine-Dershimer (1993). The results were as follows. First, a majority of participants made a limited concept map and used 22 representative categories regarding multi-cultural education and the category of 'various nations' was the most popular superordinate concept. Second, the level of knowledge in terms of the maps were generally low in so far as most of maps reached hierarchy 1. The results of the research suggested that kindergarten teachers were lacking in basic knowledge of multi-cultual education and therefore there is a real need for both conceptualization and teacher training for multi-cultual education, reviewing of current 'teachers', 'manuals', and follow-up research aimed at analyzing teacher's multi-cultual education competence.

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.

In this study, we created, implemented, and evaluated the impact of proportional reasoning authentic investigative activities on the mathematical content and pedagogical knowledge and attitudes of pre-service elementary and middle school mathematics teachers. For this purpose, a special teaching model was developed, implemented, and tested as part of the pre-service mathematics teacher training programs conducted in Israeli teacher colleges. The model was developed following pilot studies investigating the change in mathematical and pedagogical knowledge of pre- and in-service mathematics teachers, due to experience in authentic proportional reasoning activities. The conclusion of the study is that application of the model, through which the pre-service teachers gain experience and are exposed to authentic proportional reasoning activities with incorporation of theory (reading and analyzing relevant research reports) and practice, leads to a significant positive change in the pre-service teachers' mathematical content and pedagogical knowledge. In addition, improvement occurred in their attitudes and beliefs towards learning and teaching mathematics in general, and ratio and proportion in particular.

Self-compacting concrete is widely used around the globe today due to its special and unique properties. This study examines the effect of natural and crushed gravel combinations in different percentages in short-and long-term properties of concrete. The best utilized sand had a fineness modulus of 2.7. In the mentioned mix designs, silica fume was used with 0 and 7% of the weight of the cement. In order to check the properties of fresh and hardened concrete, 9 and 5 test types were performed, respectively. The carried out tests were slump flow, V-funnel, J-ring, L-box, U-box and column segregation for fresh concrete, and compressive, tensile and flexural strengths for hardened concrete. A mix with only 100% natural gravel was considered as the control mix. According to the results, the control mix design and the one containing 100% crushed gravel with silica fume were the best in fresh and hardened concrete tests, respectively. Finally, using the optimization method, a mix design with 25% natural gravel, 75% crushed gravel and silica fume was introduced as the best mix in terms of the results of both fresh and hardened concrete tests.

In response to a growing trend toward downward escalation of public school curriculum, the present study surveyed so-called extracurricular activities in kindergartens and analyzed teacher's perception of these activities. Questionnaires were mailed to 1300 private kindergartens and 1116 responses were received. Major findings were that over 89% of the respondents reported doing extracurricular activities in their kindergartens, mostly using 3-4 different kinds of special activities. The 3 most highly ranked lessons in order of frequency were English, art and physical activity. Whole group time was most often used for extracurricular activities. Kindergarten teachers were concerned with the qualifications of teachers for these activities. Teachers of these extra activities usually have no specialized training or supervised experience working with 3-through 5-year-old children.

The purpose of the present work was to study the dynamic instability of a three-layered, symmetric sandwich beam subjected to a periodic axial load resting on nonlinear elastic foundation. A higher-order theory was used for analysis of sandwich beams with soft core on elastic foundations. In the higher-order theory, the Reddy's third-order theory was used for the face sheets and quadratic and cubic functions were assumed for transverse and in-plane displacements of the core, respectively. The elastic foundation was modeled as nonlinear's type. The dynamic instability regions and free vibration were investigated for simply supported conditions by Bolotin's method. The results showed that the responses of the dynamic instability of the system were influenced by the excitation frequency, the coefficients of foundation, the core thickness, the dynamic and static load factor. Comparison of the present results with the published results in the literature for the special case confirmed the accuracy of the proposed theory.

This study examined students' menu preferences as well as the job satisfaction and specific considerations concerning foodservice operation of dieticians and nutrition teachers at special schools for the disabled. Semi-structured interview questionnaires were sent to all of the 21 special schools with direct school food service in Gyeonggi-do, and 16 dieticians and nutrition teachers agreed to participate in this study. Among the various menu groups, the subjects perceived the meat group as the most preferred and the vegetable group the least preferred. They were generally satisfactory with their job and duty, and had a strong sense of belonging to the school. However, most of them answered that they needed more time for nutritional education and counseling. While most had pride and pleasure in their job, they expressed a desire to change the system to better fit with their roles as professional nutritionists. The content analysis revealed that the subjects mainly focused on safety issues in planning the food menu and were thus limited in selecting menu items. They also felt difficulty in menu planning due to various tastes and preferences, since special schools tend to consist of a wider grade range. However, most subjects reported little trouble in food distribution and food leftovers owing to practical support from teachers and parents. The necessity for education concerning table manners and obesity prevention was generally a shared opinion, and education programs for parents were also perceived as necessary to better understand the special considerations for developing proper eating habits in their child. The study findings provide useful basic data to improve the foodservice system at special schools.

디지털 기술의 발달로 교육 현장에서는 뉴미디어 기술을 활용한 교육방법론이 다각도로 제기되고 있다. 특수교육 현장에서도 마찬가지로 뉴미디어 기술을 활용한 효과적인 교육 방안이 연구되고 있다. 이에 본 연구는 현재 특수교육 분야에서 뉴미디어 기술의 활용과 관련된 32개의 연구들을 주제 유형, 매체 유형, 교습 방식 유형에 따라 분류하여 분석하였다. 선행 연구 분석 결과, 실제 장애 아동의 교육 환경과 교수자에 대한 역할을 고려한 뉴미디어 중재 콘텐츠의 연구가 미진함을 확인하였다. 이 분석 결과에 따라 발달장애아동을 대상으로 한 상황이야기를 활용하여 사회성 성장을 기를 수 있도록 콘텐츠를 개발하였다. 콘텐츠의 기본 구조는 그림책과 같은 이야기 진행 속에서 선택의 상황을 만들고 선택에 따라 다른 결과를 경험하게 한다. 경미한 자폐증을 가지고 있는 미취학 아동을 대상으로 파일럿테스트를 수행한 결과, 아이의 콘텐츠 자체에 대한 집중과 교육현장에서의 사용 용이성을 확인하였으며, 이를 통해 중재 콘텐츠로서의 활용 가능성을 기대할 수 있다.
