In this study, we organize and explain various ways to construct 3D models in the 2D plane using Geogebra, mathematical education software that enables us to visualize dynamically the interaction between algebra and geometry. In these ways, we construct three unit vectors for 3 dimensions at a point on the Cartesian coordinates, on the basis of which we can build up the 3D models by putting together basic mathematical objects like points, lines or planes. We can apply the ways of constructing the 3 dimensions on the Cartesian coordinates to modeling of various structures in the real world, and have chances to translate, rotate, zoom, and even animate the structures by means of slider, one of the very important functions in Geogebra features. This study suggests that the visualizing and dynamic features of Geogebra help for sure to make understood and maximize learning effectiveness on mechanical modeling or the 3D CAD.

The objective of this research is to develop an effective inspection planning strategy for sculptured surfaces by using 3-dimensional Coordinate Measuring Machine (CMM). First, the CAD/CAM database is generated by using the Bezier surface patch mathod and variable cutter step size approach for design and machining of the workpiece model. Then, optimum measuring point locations are determained based on the mean curvature analysis to obtain more effective inspection results for the given sample numbers. An optimal probe sequence generation method is proposed by implementing the Traveling Salesperson (TSP) algorithm and new guide point selection methods are suggested based on the concepts of the variable distance between the first and second guide points. Finally, simulation study and experimental work show the effectiveness of the proposed strategy.

본 연구는 실업고 활성화를 위한 방안의 하나로 실내디자인 전공 교육과정의 문제점과 개선방안을 제시함에 목적이 있다. 실업고, 2(4)년제대학의 교육과정이 각각 분석.비교되었고, 실업고 재학생, 교사, 업계 종사자를 대상으로 설문을 실시하였으며, 수집자료는 빈도분포와 백분율로 통계 처리되었다. 연구결과, (1실업고에서 전공교육의 비중은 왜 높았으나 실내 디자인과 직접적으로 연관된 교과내용은 그리 많지 않았고, 홍미도와 중요성에 따라 실내디자인 전공 교과서의 활용도를 더 높이되 공업계.상업계 교과서 중 실내디자인 관련 부분을 발췌.사용하여 전문성을 높이는 방안이 강구되어야할 것이다. (22년제와 4년제대학의 전공이수학점 수는 비슷하였고, 2년제가 실내디자인실기.컴퓨터디자인.표현기법 등 실무를 위한 교과목 비율과 중요도가 매우 높은 반면 4년제는 전공실내디자인 비율이 특히 높고 연구능력함양, 전공특화를 위한 교과목이 개설되어 있으며 전공선택의 폭이 높았다. (3실업고를 대학과 비교한 결과, 실업고는 대학과 근접한 교육을 지향 하나 전문기능인 양성을 위한 체계성.전문성이 부족하므로 실내디자인과 관련이 적은 교과목을 실무와 실기능력 함양을 위한 교과목으로 대체하는 것이 바람직하다.

지상LiDAR는 토탈스테이션에 비해 신속한 측량이 가능하기 때문에 터널의 내공단면 측량을 적기에 수행하고 중심선 오차와 여 미굴량 발생을 최소화할 수 있는 강점을 가지고 있어 지상LiDAR를 이용한 터널의 내공단면 측량 및 계측이 점점 증대되고 있으며 보다 효율적이고 정확한 지상LiDAR 활용을 위한 연구도 활발하게 진행 중이다. 현재 일반적으로 터널의 여 미굴량을 계산할 때 사용되는 양단면 평균법의 경우 기존 측량 방식인 토탈스테이션 및 사진측량 등과의 비교는 많이 이루어졌으나 터널 전체의 3차원 위치정보를 얻을 수 있는 지상LiDAR를 이용하여 터널의 내공단면을 측량 체적 및 여 미굴량을 구할 때 관측간격에 따른 기준이 없는 실정이다. 이에 본 연구에서는 시험터널에 대한 reverse engineering을 실시하여 터널 내공단면 측량 시 터널단면의 체적을 비교하여 가장 합리적인 간격을 결정하고 이 결과를 토대로 현재 설계 데이터가 존재하지 않는 시험터널에 대한 CAD도면을 제작하였다. 또한 지상LiDAR 기술의 정확도를 검증하기 위하여 토탈스테이션과의 비교를 통하여 타겟좌표 정확도, 입사각에 따른 정확도 분석을 실시하였다.

This study proposes an educational direction to be followed by the clothing departments of Korea's specialized high schools in order to help achieve high levels of job placements and to strengthen their students' competitiveness. A comparison was made of the curricula in Korea's specialized high schools and in several fashion schools in other countries including the United States, Italy, France, Taiwan, and Japan. To this end, publicly available educational records were retrieved from domestic school documentation, vocational high school portals, and domestic/overseas school web sites, and were then reviewed. The archival data extracted from these sources shows that the curricula of the three chosen domestic schools uniformly focus on foundational courses such as general computer skills, general design, accounting principles, design principles, and drawing, as well as practical courses such as the design of western clothing, fashion design, fashion CAD, management of clothing material, design of Korean clothing, and knitting. Unlike these standardized courses, it was found that overseas fashion schools provide a more technically-advanced and design-focused education based on the interests of the individual student. Moreover, their education system nurtures the students' creativity through adequate field experience and history/language education. The findings of this study suggest that Korean specialized high schools should find a way to accommodate their students' interests and to provide them with personalized fashion education by adopting a more flexible curriculum. An educational line that considers the individual student's aptitudes and career path will help foster creativity and novel ideas, which, in turn, will contribute to the development of the fashion industry.

The high-tech computer technology developments have greatly affected the area of design education. Starting from the mid 80s, innovations in visual presentation methods have heightened with 2D computer graphic programs, CAD & 3D modeling, and Rapid Prototype that allows dimensional generation. The specialty and quality in design studio education have advanced due to the development in presentation methods such as Power Point and Keynote. But there are many problems with the current method of presenting the visual outcome in a data format using beam projectors, which is a vertical presenting method compared to the old studio study method of conducting discussions and reviews based on the substantial outcome. The essence of studio study that allows for comparisons and analysis by horizontally opening up the various work outcomes is being offset. Also the requirement for manual idea sketching work that plays an important role in the initial design phase continuing to decrease due to the digital working process dependence and cumbersome procedures in the presentation. In order to resolve this problem, the CALM system (Class Applied LCD Modular System) has been developed that replaces the method of attaching the sketches or renderings on the wall with a digital multi-display system. In a nutshell, individuals will upload the outcomes online and display them on the CALM system studio that is composed of 32 LCD (Columns: 4 $\times$ Rows: 8) monitors that are 19 inches in size so that various personnel can openly study the design outcomes. Also the central 42 inch PDP monitor that offers touch pad capability allows each design outcome to be described and examined by expanding. The concept phase of this development process has elevated to the production of an operating prototype that is being reviewed of its practicality. It is considered that the development of this system will decrease the extreme tendency of depending on digital operation but achieve revitalization of a more realistic and opened studio study environment compared to the individual consulting method of the old study approach.
