Recently, with the development of technology, intuitive understanding of abstract mathematical concepts through visualizations is growing in popularity within college mathematics. In this study, we introduce free visualization tools developed for better understanding of topics which students learn in Calculus. We visualize important concepts of Calculus as much as we can according to the order of most Calculus textbooks. In this process, we utilized a well-known, free mathematical software called GeoGebra. Finally, we discuss our experience with visualizations in Calculus using GeoGebra in our class and discuss how it can be effectively adopted to other university math classes and high school math education.

In this research, we designed an educational activities of exploring mathematics programs in a course of mathematics education in teacher's college. We divided future mathematics teachers into 8 groups and suggested 8 mathematics programs to them. Each group explored one mathematics program. We asked to future mathematics teachers exploring some cases that use effectively a mathematics program in the teaching of school mathematics. In the process of an exploring, we designed some activities of teaching and learning. We provided opportunities of long-term exploration, group learning, presentations, exercises, reflections to mathematics teachers. As a result, future mathematics teachers acquired basic knowledge on the usage of mathematics programs in school mathematics textbook. In addition, their capabilities that are needed to explore mathematics programs have been enhanced. Also they had learned the teacher's positive attitude through the activities of teaching and learning.

최근 국내의 각종 공사장부근에서 일어나는 가축에 대한 환경분쟁(소음, 진동, 먼지 등)피해를 호소하는 농가가 지속적으로 늘고 있으나, 피해 농가의 피해를 입증할 수 있는 객관적인 자료가 부족한데 따라 보고서를 작성하는 데 여간 어려웠던 적이 한, 두번이 아님에 많은 아쉬움을 가졌다. 각종 공사로 인해 가축 사육 장소인 목장(농장)내 도로개설 및 관통으로 인한 목장의 지속여부, 겨울철 수렵시기에 총성으로 인한 한우 성장지연, 육질 저하 등에 미치는 영향, 태양광 발전소가 축사 인근에 있어 사육 한우가 성장지연 등의 피해를 호소하는 농가가 있으나, 이에 대한 관련 연구자들의 많은 연구가 이뤄졌으면 한다. 그런 가운데서 우리 임상수의사들의 관련 자료나 정보를 입수하여 보다 적극적으로 대처하여 피해 축산농가들에 대한 보상에 도움을 줘야 하나, 피해 목장내 사육가축의 진단서나 소견서등 발부요청에 미온적이거나 회피하는 경우들을 적잖게 목도를 하고 실망감을 감출 수가 없었다. 진단서 등의 각 항목의 기재 내용의 누락, 여러 마리를 한 장(1두 1매 원칙)에 작성한다거나 유 사 조산시 정확한 월(일)령의 비기재, 환경분쟁과 관련된 피해사실의 누락이나 전혀 무관한 병명으로 발급하는 경우 및 수의사법 등에서 승인된 양식을 이탈하여 임의로 작성하는 등의 예를 간혹 보아왔는 터라 개선이 시급하다 하겠다. 임상 수의사들이 발급하는 진단서나 소견서 등은 어디까지 관련 전문가나 법원 등의 감정시 어디까지나 참고용으로 활용되고, 발급에 따른 제 비용은 인정될 경우에는 피해농가들에게 되돌려주며, 절대적으로 피해를 주는 일이 없다는 것을 강조해두고 싶다. 따라서 필자는 환경분쟁사건을 현지조사내지는 보고서를 작성하면서 아직도 우리 임상 수의사들은 새로운 분야에 대한 능동적인 대처가 더더욱 요구되는 시기에 수동적이거나 미온적으로 대하는 사례에 안타까움을 호소하며, 환경분쟁시 가축에 미치는 영향과 최근 새로이 제시된 배상액의 산정기준을 소개하여 도움을 주고 싶다.

With the program outcomes of 'the Accreditation of Engineering Education' in Korea, the acquisition and assessment of ethical attitudes as an engineer is emphasized these days. In this study, we surveyed and investigated the attitudes and ethical minds of college students majoring in information and communication engineering regarding their professional attitude and ethical behavior at present and in the future by assuming their hire in this industry. The average score of engineer ethics was 2.25 out of 5. Multi-variate regression found that the unethical attitudes of information and communication engineer were more distinct for students of older age, students with 'rude and insulting' attitudes, students who had not served in army, students who are not idealistic, and students who do not live with parents. The results provide educators with useful understandings related to the engineering ethics education program for college students.

Under the banner "Toward Global Excellence in Teacher Education", Daegu National University of Education has strived for the single aim of excellence in pre-service and in-service for over fifty years. Specially the department of Mathematics education aims to develope students' mathematical power which is related to elementary school mathematical concepts & theories. However not a few of the students seem to have test-anxiety which is relate to teacher recruitment examination. In these view, we conclude that students must have been suffered from test anxiety. Consequently the results of the study are follow. $\cdot$ 2nd paper-pencil test of the elementary school teacher recruitment(2010) has been emphasized on statement of examinee logocal thought about all 10 subjects. $\cdot$ 3rd test of the elementary school teacher recruitment(2010) has been focused on only speaking english of examinee. Thus we conclude that these Recruitment Examination(2010) couldn't minimize the test anxiety of the students. Therefore next test of the elementary school Teacher Recruitment should contain on mathematical problem-solving in elementary school mathematics textbooks.

The college of education should support pre-service science teachers to develop various abilities as a teacher, in which the teaching ability is the most fundamental one. This study is the result of a longitudinal research project following the processes that pre-service science teachers develop their teaching ability in a college of education. The data gathered include movie clips of seminar presentation, teaching demonstration, secondary school science experiment, and classes in the practicum. In order to analyze the teaching abilities in various context, a framework was developed. The framework consists of 'content,' 'progress,' and 'verbal/nonverbal' with which the movie clips of 5 pre-service science teachers were analyzed. The teaching abilities of pre-service science teachers showed overall development, that include the understanding of learners and curriculum in the 'content,' the time-management and the interaction with learners in the 'progress,' and the nonverbal behavior in the 'verbal/nonverbal.' The implications were discussed on the education in the college of education, such as the increase of teaching opportunities for pre-service science teachers and the support for those opportunities.

This study was aimed to propose a framework for the design and implementation of a competency-based curriculum for higher education institutions. For achieving the purpose, surveys were conducted with 300 companies at the southern regional area to find out core work-competencies that are needed in the work places. In addition, general education curriculum from 4 universities from the same area were analyzed and compared with the survey results to examine if the university curriculum satisfy the need of work places by providing courses that nurturing work competencies. The study found that abilities to work as a team and self-regulation are the core competencies. However, the participating universities did not provide enough courses for students to achieve the core work competencies that are mostly needed in the work places. Based on the study results, the competency based-curriculum were suggested, and the process for implementing the curriculum was discussed.
