본 연구는 애니메이션의 전문적인 특성을 고려한 드로잉 교수법을 연구하기위한 문헌분석 과정으로 뇌의 기능과 학습, 창작 기제를 고려한 교수법을 적용하면 애니메이션 드로잉능력이 효율적으로 신장될 것이라는 관점의 연구를 위한 원리분석 과정이다. 최근 들어 각 분야의 교육방법에 대한 대안적인 논의로 뇌기반 학습원리가 적용된 연구결과들이 발표되고 있다. 이는 미술과 드로잉 교육 뿐만 아니라, 예술전반적인 교육적 대안으로 적용 실시되고 있다. 반면, 애니메이션 드로잉은 미술적 소양을 필요로 함과 동시에 움직임에 대한 구조적 지식과 인지적 감각, 소통방식을 숙련할 수 있는 종합적인 교수법을 요하는 것에 비해 전문적인 교수법 개발 연구는 미진하다. 이에 효과적인 교육의 원리를 뇌의 기제로 바라보고 뇌가 학습하고 창의성을 발휘하게 되는 원리를 분석하여 본다. 또한 그림그리기와 뇌의 기능에 대한 원리관계를 통해 드로잉과 뇌의 관계를 알아본다. 그 결과 구조와 형태를 그릴 수 있는 인지적 정보를 관할하는 좌뇌 뿐만 아니라, 그리기와 직접적 관련이 있는 우뇌를 통합 발달시켜야 하며, 창의성이 발현되기 위해서는 물리적, 심리적 요소가 발현되는 통합적 뇌의 기제를 이해한 교수법이 개발되어야함이 드러났다. 애니메이션드로잉교육은 드로잉 능력에 필요한 예술적 창의 속성을 발휘하는 방법을 교육하는 것이기 때문이다. 이 과정은 기존의 애니메이션드로잉 교수법과의 차별성을 찾아내는 토대가 될 뿐만 아니라, 뇌기반-원리는 이후 교육의 전략과 방법 모형을 설계하는데 핵심적인 전략적 정의로 선정될 것이다.

This paper presents the experimental study of the static stiffness for the BT Shank(7/24 Long Taper) and the HSK Tool Shank(1/10 Short taper). The static stiffness test was performed under different experimental conditions. The results obtained are as follows ; As known in the analysis results of the Load-Deflection diagram of the 7/24 Test tool shank, it is turned out that the diagram is a linear characteristics without regard to axial drawing force and according as the axial drawing force get to the 6kN, the static stiffness of the shank increase linearly. Thus the effective axial drawing force which maintains the static stiffness of the Main spindle taper of Machine Tool is larger than 6kN. It is found that the Load-Deflection diagram with 6kN of drawing force in the 1/10 Test tool shank is characterized by non-linear. But according as the axial drawing force is increasing by the 8kN, the diagram is characterized by linear. And increasing amount of deflection is about 60%. Therefore commendable axial drawing force is larger than 8kN. As a result, considering that the actual drawing force of the Machining Center is about 1300kgf and axial drawing force 12kN is equivalent amount as a 1220kgf, it is turned out that 1/10 Test tool shank superior to 7/24 Test tool shank in the static stiffness.

This study investigated the characteristics of science imaginary pictures drawn by elementary school students and their perceptions of science imaginary drawing. To do this, $5^{th}$ graders (N=107) were selected from 1 elementary school in Gangwon province and were administered the questionnaires. Some of them were also interviewed deeply. The analyses of the results indicated that most students drew science imaginary pictures in 'land' or 'universe' of 'future' than non-science imaginary pictures. In the academic field, 'machine' was most frequently included in their pictures, and 'earth science' or 'building and traffic' was also frequently included. In addition, half of the pictures included two or more fields. Many students perceived positively the educational benefits of science imaginary drawing upon cognitive, affective, and aesthetic aspects. However, they also had several difficulties in the processes of scientific imaginary drawing such as 'difficulties in using artistic skills', 'difficulties in selecting the subject', 'difficulties in imagining', and 'difficulties in expressing my thoughts to pictures'. Educational implications of these findings are discussed.

Recently, the special alloy, for instance, such as Monel and Inconel, is used for valves, bolt/nuts, and fittings in semiconductor facility, FCEV(fuel cell electric vehicle) and hydrogen gas station, to reduce the hydrogen embrittlement. Even though the Monel material has high cost, it is recommended to use for the cases of ultra high pressure, ultra high leak-proof and so on. The purpose of this study is to investigate the characteristics of Monel material within elastic limit through the comparative analysis when Monel material is extruded or drawn. As the results, the deformation of Monel material was increased as the number of pass was increased, further, the deformation of Monel material by drawing was larger than that by extrusion. In the safety factor, the case that load is less than 420kN, the plastic deformation due to drawing could be happened faster than that due to extrusion. However, the case of more than 420kN, it showed that the plastic deformation for extrusion and drawing was almost similar.

The purpose of this study was to examine the relationship between characteristics of personality and respondent characteristics of Kinetic Family Drawing for young children. The subjects were 170 children(110 boys and 60 girls). The personal interview contained Personality Characteristic Test for young children(In-Sub Song, 1993) and Kinetic Family Drawing Test(Burns and Kaufman, 1982). Results of the test were analyzed by t-test and ANOVA by SAS program. Results are followings. First, chileren's sex and the general tendency of personal characteristic showed significant difference in the emotional personality among 4 personality characteristics. Girls show more positive tendency than boys in moral, physical, appearance and feature which expressed personal feeling and emotion. Also, girls showed more positive tendency than boys in personal characteristic which showed physical ability. Second, Children's sex and individual characteristic in Kinetic Family Drawing respondent characteristic showed significant difference in own's arm length. Also, Using a rare of paper and chapter 1 of the power among the family showed significant difference in styles and symbols. The boys drew lengther arms compared with their height than the girls. The girls were less complicative, anxious, comparative and aggressive for their family. Third, As a result of the study about the relationship between 4 personal characteristics of children and individual's behavior in Kinetic Family Drawing respondent characteristic, the significant difference is showed in academic personality and social personality had higher completion of their father's feature and drew bigger feet. In socal personality, negative behavior than positive children. Fourth, As a result of the study about the relationship between 4 personal characteristics of children and individual's characteristic, the significant difference were found in academic personality, social personality, family personality and emotional personality. Children with negative academic personality drew longer arms than children with positive academic personality, social personality and family personality. Also, Children with negative emotional personality drew more siblings than children with positive emotional personality. Fifth, The academic personality and the social personality had significant difference in the relationship between 4 personal characteristics of children and dynamics. In social personality, normal children were more tendencious to look at the important person with their mother's direction than positive children. Sixth, In terms of the relationship between 4 personal characteristics of children and mode, academic personality and family personality showed significant difference. Children with negative academic personality used more edge of papers than children with positive academic personality and children with positive academic personality and children with negative family personality fold more papers than children with positive family personality. At last, there were no significant difference between 4 personal characteristics of children and styles as well as symbols.
