Feature-based NC machining, which requires high quality of 3D CAD model, is widely used in machining aircraft structural part. However, there has been little research on how to automatically detect the CAD model errors. As a result, the user has to manually check the errors with great effort before NC programming. This paper proposes an automatic CAD model errors detection approach for aircraft structural part. First, the base faces are identified based on the reference directions corresponding to machining coordinate systems. Then, the CAD models are partitioned into multiple local regions based on the base faces. Finally, the CAD model error types are evaluated based on the heuristic rules. A prototype system based on CATIA has been developed to verify the effectiveness of the proposed approach.

The purpose of this study is to design a Content-based Korean Class model using Flipped learning for foreign students. The class model that presents on this paper will lead the language learning through content learning, also it will be enable the student more active and to have an initiative in the class. Prior to designing a Content-based Korean Class model using Flipped learning, the concepts and educational significance and characteristics of flip learning were reviewed through previous studies. Then, It emphasizes the necessity of teaching method adapting Flipped learning to Content-based teaching method in Korean language education. It also suggests standards and principles of composition in Contents-based teaching method using Flipped learning. After designing the instructional model based on the suggested standards and principles, it presents a course of instruction about how learning methods, contents and activities should be done step by step. The Content-based Korean class model using the Flipped learning will be an alternative approach to overcome the limitations of teacher-centered teaching methods and lecture-teaching methods which are the dominant of present classroom environment.

The domestic Radiation Technology is integrated into and utilized in various areas and is closely related to the industrial growth in Korea. The domestic use of radiation and RI (Radioisotope) increases in quantity every year, however the level of technology is poor when compared to other developed countries. Manpower training is essential for the development of Radiation Technology. Therefore, this study aimed to propose a methodology for designing systemic education and training model in the field of measurement and analysis of radiation. A survey was conducted to design education and training model and the training program for measurement and analysis of radiation was developed based on the survey results. The education and training program designed in this study will be utilized as a model for evaluating the professional development and effective recruitment of the professional workforce, and can be further applied to other radiation-related fields.

This article aims to analyze the experience of designing and operating a class model linking undergraduate and graduate students in engineering education and suggest its development direction. To achieve these objectives, the undergraduate-graduate linked class model was applied to community problem-solving education and a case was analyzed. It also specifically presented the process of how we design the class model and what the actual operational performances and improvements are. This study found that undergraduate and graduate students could build integrated and horizontal cooperative relationships in their classes through undergraduate-graduate linked education and, particularly, graduate students could gain meaningful educational experiences. However, it was difficult to obtain tangible performances through the team activities of these students within a semester. In order for engineering colleges to operate undergraduate-graduate linked education, it would be necessary to provide a longer and more systematic educational environment and better curriculum. The study tried to seek specific tasks and ways to improve them.

Most of a courseware evaluated negatively by short of instructional strategy to improve learning effects. Designing a courseware is a time-taking and challenging task. Therefore, a method is required that helps to easily design courseware that is effective to learning. This study proposed a method for designing and management courseware by utilizing a metacognitive strategy. We made a design the coursewase efficiently using concrete instructional model frameworks as metacognitive stragety and tried to improve the quality of courseware for learning effects. We applied our proposed method to teacher's college students in Korea who were taking the "Courseware Development" course. After analyzing it's effects, the responds can design courseware easily and monitor the design direction while their designing. Also, they can design the courseware systematically and implement detail instructional strategy by using concrete instruction model frameworks as metacognitive strategy. However, they were not easy to develop concrete instructional model frameworks at first and we need sharing it among the designers.

Students experience many problem solving activities in school mathematics. These activities have focused on finding the solution whose existence was known, and then again conjecture about existence of solution or posing of problems has been neglected. It needs to put more emphasis on conjecture and problem posing activities in school mathematics. To do this, a model and examples of designing mathematical activities centered on conjecture and problem posing are needed. In this article, we introduce some examples of designing such activities (from the pythagorean theorem, the determination condition of triangle, and existing solved-problems in textbook) and examine suggestions for mathematics education. Our examples can be used as instructional materials for mathematically able students at middle school.

Purpose: The purpose of this study was to improve the quality of fundamental nursing practice course. Methods: Participants were 132 students who took the fundamental nursing practice course at D university in N city. The study included processes of planning, action, observation, and reflection. Quantitative data were analyzed using SPSS 20.0 program and qualitative data were evaluated through content analysis. Results: The 12-step designing college courses model by Fink was applied in the planning. In the acting stage, the course was conducted according to the instruction in designing the course, students wrote reflective journals and the professor gave feedback to the reflective journal and the class observation journal was used for lessons. In the observation stage, the course evaluation was surveyed and analyzed, evaluations were positive with 47.1% of students positively evaluating the teaching strategy. In the reflecting stage, outcomes in course improvement were reflected on and, the number of students at the lower level-of-achievement decreased. Conclusion: Action research was a useful research method that could capture the quality improvement process in college courses. Expression of effort and passion to improve quality of education through action research in various ways and to share quality improvement strategies for nursing education are important.
