  • In this paper, we present a new approach for the automation of deburring process. An algorithm for teaching skills of a human expert to a robot manipulator is developed. This approach makes use of TSK fuzzy model that can express a highly nonlinear functional relation with small number of rules. Burr features such as height, width, area, cutting area are extracted from image processing by use of the vision system. Cutting depth, repeative number and normal cutting force are chosen as control signals representing actions of the human expert. It is verified that our processed fuzzy model can accurately express the skills of human experts for the deburring process.

  • The purpose of this paper is to report the process of curriculum renewal of an intensive English program with focus on the perceptions of the people involved. The researcher tries to describe the five years of curriculum change. The data collected through surveys, interviews, and observations were analyzed. The findings show that throughout the years, the students that participated in the program perceived that their English skills have improved. The teachers also thought that the student's overall English skills improved. The satisfaction on the chosen textbooks was higher in the student group than the teacher group. The main goal and objectives of the intensive English program in the study changed in the process of curriculum renewal. The program that launched in order to enhance students' conversational skills in 2004 started to include TOEIC instruction in late 2005 due to students' needs. The students were content with the fact that there were many teachers in the program whereas teachers had neutral opinion. The present study aims to suggest the importance of curriculum renewal through program evaluation which can be applied to similar language programs for the continuity and longevity of the programs.

  • 중학교 3학년 학생들이 과학적 탐구과정기능에 대한 자기평가를 신뢰롭게 할 수 있는지 알아보기 위해 학생의 평가가 교사의 평가와 얼마나 일치하는지, 교사에 비해 자신을 얼마나 높게 혹은 낮게 평가하는지 알아보았다. 학생들은 탐구과정 기능에 초점이 맞추어진 점검표를 이용하여 개방적 탐구 후에 작성한 보고서를 자기평가 하였다. 학생의 자기평가와 교사의 평가가 일치하는 정도는 평균 73% 이었다. '자기평가능력'의 남녀간 차이는 없었으나, '성취도'를 기준으로 한 상 중 하 집단의 차이가 있었다. '자기평가능력'은 '성취도와 상관이 있는 것으로 나타났고, 여학생의 경우 상관 관계가 더 높았다. 탐구과정기능의 영역 중에서 '자기평가능력'이 높은 영역은 결과정리 및 해석 영역이었고, 가장 낮은 영역은 결론도출영역이었다. '자기평가경향'을 분석한 결과 전체 학생들은 평균적으로 교사보다 자신의 능력을 조금 높게 평가하였다. 탐구계획 영역의 항목들과 변인통제 항목은 교사에 비해 자신을 낮게 평가하였고, 결론도출 영역의 항목들은 교사보다 자신을 높게 평가하였다. 상위권 학생들은 교사보다 평가항목에 대한 기대 수준이 높아 자신을 낮게 평가하였고, 특히 하위권 학생들은 평가항목에 대한 기대수준이 교사보다 낮아 자신을 교사보다 높게 평가하는 경향이 두드러졌다.

  • If we can evaluate the training results more appropriately and analyze the psychological changes in more objectively, the training can be more efficient and it can help to solve the problems during the training. This research analyzed the similarity and differences of Yangseng Qigong and psychological skill training's components and measurement methods. Also, the research further studied psychological skill training's measurement method. Results : The measurement type of Yangseng Qigong are Sagong, a record of Sagong, Damgong, IIgi, and Sogyeol. Similarly, the measurement type of psychological skills training are questionnaire, interview, personal profile, and observation of a single subject. Despite the similarities between the measurement type of Yangsaeng Qigong and psychological skills training, unfortunately there are differences in the contents. Thus, If we introduce strengths of each method to the other, we may have better measurement methods. The questionnaire method of psychological skills training is the most commonly used method, because it gives concrete, objective, reliable and highly reproducible results. If we refer to the questionnaire development process in psychological skills training, we can have objective and concrete measurement tool for Yangsaeng Qigong training. In the psychological skills training measurement tool development process, there are 5 stages; test conception, test preparation, test execution, question analysis, and test modification. Furthermore, the requirements for the good survey are reliability, validity, practicality, and cultural appropriateness. Through this study, we reached the conclusion that we need to combine two methods together to develop a better method because Yangsaeng Qigong places importance on comprehensive method and realization while psychological skills training places importance on analytical method and objective evaluation. And It seems that a practical study is needed to resolve the concerete problems of Yansaeng Qigong through these concrete cases.
