Cognitively Guided Instruction (CGI) is one of the most successful professional development programs for elementary mathematics teachers in US. This article introduces its theoretical background, research-based framework of addition and subtraction work, and how the program has been disseminated. Carpenter and Fennema started CGI aiming to develop a professional development program that focused on research knowledge of children"s thinking. Their goal was. to bring a significant change in teaching by helping teachers understand how children think mathematically. This 3-year NSF funded project grew to be 11-year long, and a number of publications have reported consistent successful learning and teaching by CGI students and teachers compared to counterparts throughout US. CGI′s success by focusing on improving teachers′ knowledge of children′s thinking offers possible opportunities for teacher educators to re-conceptualize teacher education in Korea.

Purpose: The purposes of this study were to provide information about safe actions during the practice of dental technology, promote belief in safe actions among the students of dental technology, and reinforce their knowledge about how to act safety. Methods: Open questions were asked to 120 sophomores majoring dental technology to understand the target group's belief about safe actions. Following the instructions by Ajzen & Fishbein, the collected data were grouped according to similar beliefs. Those beliefs of the highest frequency were given a priority and got to represent the belief level of the target group. Even with belief changes, however, they would not be able to practice safe actions if they had no knowledge about how to do safe actions. For desirable behavioral changes among the students, the students were then asked to discuss the current state of safety accidents and issues focusing on the materials and processes used in the practice and give presentations regarding the subjects to identify risk factors. Then the identified risk factors were used to devise the program contents so that the students could practice safe actions through accurate behavioral approaches and belief changes by educating them about how to act safely by the practice processes and the involved materials and devices. Results: Not only do the students of Dept. of Dental Technicians have difficulties with the complex practice processes while practicing to make dental prosthesis, but they are exposed to the risk of accidents as they're poor at dealing with the materials and devices. Although there is a definite need for accident prevention education programs before practice, the reality is that the school doesn't the schoosuch education. Based on the judgment that an education program designed to reinforce belief for behavioral changes would generate effgrams results, an education program was developed by applying the Theory of Planned Behavior(TPB). Along with their beliefs, the current state of accidents n. Basepractice, demand for safety education, and practice level of safe actions were used to device the contents of accident prevention education and to develop an accident prevention education program for dental technology. Conclusion: The study presents an accident prevention education program developed to reinforce dental technology students' beliefs and knowledge and to help them do safe actions during practice.

Gear tooth micro-geometry modifications include the intentional removal of material from the gear teeth flanks, so that the shape is no longer a perfect involute. If the gear shapes are perfect, then the gear tooth meshing is better, therefore the gears will transmit input torque in a more efficient manner without the generation of high frequency engine fluctuation noise. In this paper, we study tooth micro-geometry optimization of rear gear set in 2 speed planetary gear reducers. Analysis revealed problems which are need of modification. Based on the results, tooth micro-geometry was used to deal with load distributions on the rear gear set.

Since Environmental Education in Elementary School is taught separately in various subject area, a well-founded and organized curriculum in integrated Environmental Education is needed to educate teachers for professional development. In this research, a curriculum for elementary teacher in-service training program was developed in order to improve both environmental and educational competencies of elementary school teachers. The curriculum was based on the needs analysis on Environmental Education training for elementary school teachers. Also it was based on international and updated perspectives on Environmental Education, Education for Sustainable Development. The curriculum consists of the introduction and the particular perspectives. The particular is made of 60 hours, which covers 6 perspectives on environment. They are ecological perspective, environmental ethics perspective, social-cultural perspective, economic perspective, environmental hygienic perspective, and environmental policy. Environmental policies of Korea and the world were included so that teachers will understand efforts made at national level and participate more to environmental action in their schools. Lesson objectives were specified for teachers to apply this curriculum to their classroom easily. Related elementary curriculum and textbook were indicated at the end of each lesson so teachers can link their training setting with their classroom setting. Especially, in this curriculum various teaching and teaming methods for each lesson are introduced. Thus, this re- search is very practical for elementary school teachers who are planning to teach environment in their classroom.

This study is aimed at providing basic information necessary to set up education program and strategies to prevent high school students from smoking by school health care service. The main groups of study are 814 third-grade male students, 557 parents and 362 teachers, who were randomly chosen at 8 high schools in Seoul. Date analysis consisted of Chi-square test and percentage. The findings of the study are as follows: 1. The less interesting family life is, the more increasing current smoking rate is, (ex-smoking rate 53.5%, re-smoking rate 40.3%, current smoking rate 24.3%) 2. According th the results of $x^2$-test for the school life and the smoking, the students above ranking 41 showed th increase as 48.7% for continuous smoking, 18.9% for re-smoking, 67.6% for the present smoker. But it turned out that the students belonged to ranking 10 were not experienced the smoking. So it showed that there was a correlation between score and smoking. 3. It is noted that 93.3% of students, 93.3% of parents and 96.1% of teachers recognize harmful effect of smoking. But less than 70% those have recognized only half of all smoking knowledge. 4. There is a significant difference in the contends and types of education between parents and teachers. 5. For the time of home education and school health education to prevent the smoking, it turned out that 44.9% of students, 42.4% of parents, and 47.4% of teachers considered the optimal time as a high school' days. In addition it appeared that 40.5% of students, 33.4% of parents, and 54.6% of teachers recognized the necessity of the early education before the elementart school. For the optimal time to begin school health education, it showed that the middle school days were indicated from 56.6% of students, 52.7% of parents, the elementary school days were 54.6% of parents, the elementary school days were 54.6% of teachers.

The cooperation between universities and industries is already one of the most important factors driving the national economy in the knowledge-based society of the 21st century represented by the Fourth Industrial Revolution. The Korean government has also been carrying out legal and institutional re-adjustments to promote industrial-university cooperation in line with demands for such changes in the times. However, despite this industry-academic cooperation system, there is still a significant mismatch between industrial demand and the university's workforce development system. By the way, there is a Cooperative Education(CO-OP) in Canada and the United States. It's an innovative link between the university and the industry. The reason is that the CO-OP program not only allows students to gain experience with their majors in the industrial field, but also plays a positive role in improving their specialty expertise. In particular, field information, ideas, and job insights that students acquire through CO-OP also serve as motivation for starting a business beyond employment after graduation. Furthermore, CO-OP experience is an important opportunity for future researchers to come up with commercialized research results that are not separated from the field sites The purpose of this study is to overcome the gap between industrial demand and the college manpower training system, and develop a Korean-style coaching program model as a growth engine for creative talent-building policies, represented by 'creation of start-ups and new industry.' In addition, this study suggested measures that can be applied in real universities. In addition, the study also highlighted that the introduction of CO-OP programs with field practices in Korea could also boost start-ups. Based on the Korean CO-OP program model, the curricula applicable to domestic universities consisted of two types : general and research-oriented university types.

According to the Gartner Group, the market for ERP software in Korea is growing rapidly. However, the number of successful ERP implementations is quite few. Standard(unmodified) ERP's are built based on best practices. Improvements expected from successful implementation are based on best practices built into the software. Many improvements are lost through modification to "standard" software. Even minor changes in software can significantly reduce benefits. Both implementation time and risk factors are increased with modifications. We introduce a methodology, called package Enable Re-engineering (PER) and the main components of change management program by Ernst & Young. "To-Be" model could be developed through the software capabilities. And change management processes such as continuous education and self-developments are required. The philosophy of the change management processes is to let the software package drive the re-engineering practices and avoid moving the software toward the "As-IS" process. Extensive top management involvement, major focus on speed, extensive communication program, and "clear" picture of the future are essential components of change management. We are sure that the complied experiences and model have implications for practice and for academicians for their endeavors in their fields.
