This study is one of the continuous work following the preceding analysis in 1977 which has suggested some data in the better improvement of evaluation methods on the students' achievement. Throughout the study, the academic records of 1,699 YJCT freshmen have been used as the reference materials. The main results obtained by this study have revealed the following: First, differences of standard in marking the test scores among the individual course subjects are still existing. Second, the achievement scores of the general selection students for the college admission are higher than the special selection students in the subjects of general education course such as Korean, Ethics, History, English and Mathematics, but contrary lower in the major subjects. Third, the scores for college admission including both Preliminary College Entrance Examination and High School Achievement are not so highly correlated with the college achievement scores as expected. Fourth, no distinct differences have been found according to the years passed after the high school graduation. The college academic achievement scores of the technical high school graduates, however, seemed to be influenced by the reputation of their parent schools. With the above results, it is suggested that a professional study to develop the better selection system of entrance examination, to improve the methods for instruction, evaluation and organization of the course subjects, and to render more effective student guidance should be continued.
지능형 교수 시스템(ITS)을 위한 전문가 모듈의 연구

This paper proposes an expertise module as Intelligent Debugger which is a component of Intelligent Tutoring System. The module organized with the programming knowledge of arithmetic expression in the Pascal language. The knowledge representation of the module uses both frame-based method and semantic network, and it is displayed through semantic analysis process. The module has the functions that discovers misconceptions and bugs of a novice student's programs, and provides them the solutions for their corrections. It is believed that repeated practice through ITS will help the novice students learn Pascal language more efficiently.
音樂敎育에서 育成될 精神的 效果 : 韓國 音樂敎育을 中心으로 with refernce to music education in Korea
金正斗 全北大學校 師範大學 1983 사대논문집 Vol.9 No.-
Psychological effect which will be fostered through music education means a mental process through which we can appreciate the beauty of thins with a fine sesibility. In other words, with such a feeling we can discriminate the beautiful from the ugly and appreciate the beautiful with an aesthetic sentiment. Musical aesthetics is spiritual reception through which we can approach the true nature of human being. Then what are the effects of music education? Music education enables us to purify and improve our characters. It can relieve our humanities properly and help them to be highly elevated. With the help of well-tained music education, we can get away from the complexity of human life and noise pollution. Music education makes our lives encouraged, hopeful and full of vitality. With only musical experience, music education enables us to express our creative feelings confidently. It also enables us to maintain warmth, interests, abilities, and hopes in the human life and preserve mutual aid, sincerity, affection and saintdom in the social life. To sum up, it is concluded that psychological effect fostered through music education is to elevate the absolute value of intellect and emotion which are prerequisite to the education of the whole man.
연속 방전드레싱에 의한 경취재료의 경면연삭에 관한 연구
김정두,이은상 대한기계학회 1994 대한기계학회논문집 Vol.18 No.3
Ferrite is widely used in the material of magnetic head, but is difficult of grinding because of their brittleness and hardness. Therefore, diamond wheel with superabrasive is required for surface grinding of this brittle material. But the conventional dressing method can not apply to the diamond wheel with superabrasive. In this study describes a newly proposed method for carrying out effective inprocess dressing of diamond wheel with superabrasive. Using the IEDD the surface roughness of workpiece was improved and grinding force was very low. Resently IEDD is good method to obtain the efficiency grinding and surface grinding of brittle materials.
반응표면분석법에 의한 화인세라믹스$(Al_{2}O_{3})$ 원통래핑의 최적화에 관한 연구
김정두,최민석 대한기계학회 1994 대한기계학회논문집 Vol.18 No.4
Cylindrical fine-ceramics, $Al_{2}O_{3}$, was lapped on its outer surface by vibrational lapping unit manufactured in the laboratory. Cylindrical lapping of fine-ceramics is necessarily be characterized and optimized because its process as other finishing methods is time-spending and, so, inefficient one, and because it is very complicated and random process affected by numerous factors in itself and in its environment. In this study, an efficient experimental approach, experimental design method, was used to analyze characteristics of the cylindrical lapping of fine-ceramics, $Al_{2}O_{3}$, and response surface methodology(RSM) to find out the optimal variables combination for the maximum improvement of surface roughness($R_a$). From the final surface roughness point of view in the given lapping conditions, a stationary point or optimal lapping conditions as well as the possible maximum improvement of surface roughness($R_a$) was predicted.

The systematic study from intuition to creative activities in music is much more needed than in other branch of art. The creative work is produced without intuition. Intuition is worked into creative activities through the sense and spirit. I have divided intuition into two parts ; positive and general intuition. They create the original and creative and work deveolped into revelational and intellectual sympathy inspired by spirit, and supported by music intuition such as the sense of phrase, rhythm, time, melody, harmony and composition. They also unify human behavior and music expression.
