평생 교육이 화두가 되는 현대 기술 및 지식정보화 사회에서, 사회인이 재교육 등을 위하여 전통적인 교육의 형태로 재교육을 받는 것은 쉬운 일이 아니다. 전통적인 교육 형태가 제공하지 못하는 교육의 기회를 현재 널리 응용되고 있는 Cyber 강의가 줄 수는 있지만, 실험 실습 등이 요구되는 산업체 기술 교육을 위한 Cyber 강의는 일반적인 이론 강의를 위한 Cyber 강의에 비하여 새로운 제작 방법 등이 요구되어진다. 본 논문은 산업체 기술 교육을 위한 Cyber강의 제작 방법을 제안하고 실제 구현을 통하여 그 활성화 방법을 보이고자 한다.

Ultra High Definition(hereafter UHD), Next-generation video technology, was quickening in the request of many years of the recipient and the authors who have been towards the higher sense of reality. The change of the medium has resulted in a mutation in the detailed content and the point of view overlooking the world as evidenced through the history. Thus the emergence of UHD will also be expected to require to manufacture unique technology. Therefore, this paper, especially in the documentary among the video content, tries to study the changes in the manufacturing process by UHD video technology. Moreover UHD video screen technology such as high resolution tries to analyse for the fitness for purpose of the documentary that transmission of the accuracy and the change from a documentary video production. In addition, I try to explore the improvement in the choice of shooting material expected to be a problem, even for the advance of the work on the second half and backup according to the enormous data. We derive the developmental aspects that UHD video technology in documentary production is brought about by the research plan described above. It is intended to contribute to the development of content production with the development of technology.

In the future there would be many kinds of digital images for many industrial markets. 3D stereoscopic images for variable fields; medical operation, film and animation, broadcasting, internet, game, or design for art and architecture. And many people to work about computer programming, and digital image making will concern about it more and more. However, these kinds works and studies are focused on the professional technical fields like 3D display or computer programming technology so far. To revitalize the market of a variable stereoscopic contents, there should build up the foundation for easy processing of the making stereoscopic images. This paper is based on stereoscopic making skills for anaglyph system. An anaglyph system has an old history about making stereoscopic images, and very simple method to produce the stereoscopic images. Particularly this study is focused on color compositing technique, and camera positioning on the compositing system. It will help optimization of the environments to create 3D motion graphic and animation contents.

본 논문에서는 기존의 채널기반의 오디오 기술에 대해 다양한 서비스가 가능하고, 재생환경에 독립적인 객체기반 실감음향 기술에 대해 논하고자 한다. 현재, 극장 사운드를 중심으로 객체기반 오디오 기술이 적용된 사운드가 점차 확산되고 있으며, 미국, 유럽 등 차세대 방송용 오디오에 객체기반 오디오 기술의 도입을 적극적으로 고려하고 있다. 객체기반 오디오 기술은 콘텐츠의 제작단계에서 재생환경을 고려할 필요가 없고, 현장의 음향을 신호와 3 차원 공간 정보로 구분하여 음향 공간의 정보를 그대로 표현함으로써, 재생환경에서는 3 차원 공간 정보를 활용하여 다양한 3 차원 음향 재생 기술을 활용하여 재생할 수 있다. 이러한 객체기반 실감음향 기술 개발을 위해서는 편리한 제작 및 3 차원 공간 정보 표현 기술이 필요하며, 청취환경에서는 객체기반 실감음향 콘텐츠를 제작자의 의도대로 렌더링할 수 있는 재생 및 제어 기술이 필요하다. 이에 객체기반 실감음향 기술의 기술동향과 객체기반 실감음향 서비스를 위한 콘텐츠 표현/제작 및 재생 기술에 대하여 고찰해 보고자 한다.

3D printing technology is a manufacturing process for products, in which polymer and metal materials are laminated to form structures. It is advantageous for manufacturing parts requiring a high degree of design freedom and functionality. In addition, it would be a suitable technology for the production of parts for railway vehicles in the future, due to the need to produce parts in small quantities. In order to fully exploit the advantages of 3D printing technology, it is necessary to consider the process characteristics during the design of the product. In this study, the redesign and manufacturing technology of the product considering the performance and process conditions were studied for the heat exchanger in the air compressor of railway vehicles, as a trial application of the 3D printing technique. First of all, the design concept to improve the performance of the heat exchanger was defined, and the design range was specified to satisfy the performance of the present heat exchanger analyzed experimentally. Then, the detailed design was revised considering the characteristics of the metal 3D printing process, such as the manufacturing restrictions and production time. Based on the final design, the product was fabricated by the 3D printing process using aluminum material, and it was confirmed that the dimensional accuracy was satisfied. The weight of the final product was reduced by 41% compared with the existing products. The results of this study will make it possible to develop an efficient product design process for 3D printing technology.

Recently, free-formed construction technology is becoming a new measure of representing technological superiority and sociocultural ingenuity. However, the CNC processing technology utilizing the existing wood and iron form has limitations in terms of the manufacturing time and material cost. Therefore, in this study, the method and process of manufacturing free-formed EPS form using S-LOM-based 3D printing technology were suggested. Furthermore, through the mock-up test, a comparative analysis of the manufacturing time and precision with CNC milling technology was conducted. The results show that S-LOM-based 3D printing technology has reduced manufacturing time about 57.4% compared to CNC milling technology during the free-formed EPS form manufacturing process. In addition, compared to the design drawings, the maximum error value was 20.5mm, proving the applicability of S-LOM-based 3D printing technology. The results of this study are expected to contribute to the improvement of S-LOM method and the activation of S-LOM method by verifying the applicability of S-LOM-based 3D printing technology.

지난 세기부터 MEMS 제작 기술을 이용하여 만들어진 시스템들을 의학이나 생물학적인 용도로 응용하기 위한 많은 연구가 활발히 이루어져 왔다. 기술적인 측면에서 이러한 연구들은 MEMS 분야의 초창기에 강조되어 온 표면 및 몸체 미세 가공 기술(surface ＆ bulk micromachining)과 같은 미세 구조물 제작 기술의 발전에 힘입은 바 크다. 그러나 MEMS 기술이 점차 발전되어 오면서, 가공 기술이 고도화되고 미세 시스템의 구조가 점차 복잡해짐에 따라, 많은 연구들이 단순한 가공기술을 넘어 미세 시스템을 조립하고 집적화할 수 있는 기술, 접합 (bonding) 기술, 패키징 (packaging) 기술, 3차원 형상의 제작 기술, 실리콘(silicon)이나 유리(glass)가 아닌 다른 재료를 이용한 미세 가공 기술 등의 개발을 중심으로 이루어지고 있다.(중략)
