Nowadays application of modem achievements of information technologies in science, engineering and education is usual phenomenon. Application of these technologies allows easily creating new methods of learning of mathematics. More of new methods of creation of multimedia electronic manuals on high mathematics are founded to application of multimedia and communication opportunities of the computer. But application only multimedia and communication opportunities of the computer at creation of multimedia electronic manuals on high mathematics is insufficient to elimination of 'gap' between training and studying high mathematics. So, we offer a new way of the decision of this problem: creation of a multimedia electronic manual on high mathematics with built-in a mathematical environment MathCad in the national language.

The design of injection molded polymeric parts has been done empirically, since it requires profound knowledge about the moldability and causal effects on the properties of the part, which are not available to designers through current CAD systems. An interactive computer-based design system is developed in order to realize the concept of rational design for the productivity and quality of mold making. The knowledge-based CAD system is constructed by adding the knowledge -base module for mold feature synthesis and appropriate CAE programs for mold design analysis in order to provide designers, at the initial design stage, with comprehensive process knowledge for feature synthesis, performance analysis and feature-based geometric modeling. A knowledge-based CAD system is a new tool which enables the concurrent design with integrated and balanced design decisions at the initial design stage of injection molding.

CAD system is a very important technology in designing the products which we are using today. This CAD technology has been enlarging its area into 3D CAD systems with the development of computer graphics technologies. In particular, such advances have been realized in special area such as the CAD system for designing shoes. However, because it is difficult to design a 3D CAD system, most CAD developments except for major CAD software companies usually have employed the AutoCAD which realizes 3D concepts. Also, many shoes' designers have been skilled with 2D shoe CAD systems and then they can make high achievements. Therefore, we design a new shoe CAD system with advantages of 2D CAD system and 3D CAD system. We also implement the scheme to transfer the data between 2D CAD system and 3D CAD system and also grading technologies to get patterns of various shoes size from a basic shoe's design.

80년대부터 국내에 도입된 CAD/CAM시스템은 금형 및 관련 제조업체, 자동차 제조업체, 플랜트 /조선업체 등에서도 제도, 설계 및 설계해석용, CAM을 이용한 NC 가공용 등으로 적용되고 있다. 그러나 CAD/CAM 시스템을 판매업체의 불충분한 교육과 아프터 서비스가 아직 미흡하여, 시 스템 사용업체의 경우 시스템 활용기술 부족, 기술인력 부족 등의 이유로 활용도가 높지 못하다. 그럼에도 불구하고 많은 업체들이 CAD/CAM 도입을 본격적으로 준비하고 있으며, 93년의 경우 90년에 비해 사용자수가 2배가 되리라는 전망이다. 많은 업체의 경우 인원절감, 시간단축, 경비 절감 등의 비용효과와 정밀도/정확도 효과 등의 업무수준 향상 효과를 기대하며 추진하고 있으나 표준화, 관리의 체계화 효과 및 기업이미지 개선, 직원의식 수준 향상 등의 상징적 효과도 크다고 볼 수 있다. 국내에 CAD/CAM 시스템 보급을 촉진하기 위해서는 소프트웨어의 한글화 작업이 이루어져야 하고 분야별로 다양한 데이터베이스가 구축되어야 할 것이며, 가격이 저렴하고 속 도가 빠른 형상 모델링 기술발전이 요구된다. 끝으로, 우리 실정에 맞는 CAD/CAM 소프트웨어의 국산화 작업이 우리가 풀어야 하는 최대 과제라 할 수 있다.

The purposes of this study were to investigate, analyze, and consider the feature and practical situation of Apparel CAD education and distribution situation of CAD system so that CAD education can be effectively operated and managed in various kinds of relevant schools and universities. 32 colleges and universities that are performing CAD educational system are selected for the study. The author of the study has investigated and obtained the information through questionnaires to 32 professors who are in charge of CAD lectures and 301 students who are receiving CAD education. The result is as follows. 1. It showed that 62.5% of CAD educational systems have been practically introduced after 1995. Regarding the using system, YUKA occupies 46.9%, PAD 21.8%, and GERBER 18.8% and these three kinds of system have been chiefly supplied. 40.6% of them own only one system, 37.5% of them own 2～5 systems and 78% of them own less than 5 systems. 2. The most seriously pointed problems during the operation of CAD system were the lack of experimental materials and the frustration of manpower supply. Thus, the CAD education programs in schools and universities are practiced in inferior environments internally and externally. 3. Regarding the practical situation of CAD education, 28 among 32 schools and universities are performing CAD as one of the regular subjects for the curriculum. 4. Regarding satisfaction degree of the using system, professors showed higher satisfaction degree than students did. In conclusion, it showed that although the practical situations of CAD education in schools and universities have been changed and improved so much since 1995 owing to the increase of the positive recognition of the necessity of CAD, many students in the educational sites cannot study their favorite subjects related with CAD program with interest due to the lack of experimental facilities, the poor computer management systems, and the problems of manpower supply, etc.

The purpose of this study is to suggest effective online pedagogical strategies for a fashion design CAD course to enhance student learning and satisfaction. The study investigated student experience of online learning and compared online learning with a face-to-face learning experience. Student concentration, participation, perceptions of effectiveness of teaching, utilization of learning materials, and satisfaction were analyzed using a 5-point Likert scale. Advantages and disadvantages of online learning as well as advantages of face-to-face learning were also analyzed both quantitatively and qualitatively. Student concentration, participation, and perception of effectiveness of teaching were greater for face-to-face learning with significantly higher concentration on individual practice. Students utilized video recording of synchronous online lectures more actively than PDF lecture notes. The advantages of face-to-face learning were plentiful communication and feedback and easy questioning process as well as high levels of understanding and concentration. Meanwhile, major disadvantages of online learning were the speed of the lecture, lower levels of understanding and concentration, limited peer interaction, and technical problems. Major advantages of online learning were flexibility and convenience, repetitive learning through videos, and instant communication and feedback. Students preferred a blended learning approach for the fashion design CAD course. For effective online learning, it is suggested that instructors frequently question and check student practice through screen share in a private online meeting room and engage activities that are demanding of student interaction. The video recording of synchronous online lectures is also suggested as a supplemental learning material for repetitive learning.

The purpose of this study is to observe the teaching method and cognition process in using the PAD, Lectra and Investronica pattern CAD system. It is necessary to gather information about apparel pattern CAD to enable clothing and textile educators to efficiently incorporate CAD into their curricula and to provide more substantial information. Interviews and questionnaires were used in the research and twenty four questionnaires were used for data analysis. The results of this study are as follows: 1) Students thought that new technology such as apparel pattern CAD is important in the apparel industry, and they have a positive vision toward such innovation. 2) Student who study harder during in CAD class worked easily of all PAD, Investronica and Lectra system. 3) The most preferred teaching method is to small group instruction by the instructor and then having feedback from the instructor. 4) Students realized that they needed to take prerequisites subjects like clothing construction. 5) The most interesting step is the pattern grading system and the least interesting but easiest step is digitize for patterns in the Investronica system.
