In case that the datums chosen for dimension on engineering drawings are unsuitable for manufacturing and inspecting and inspection purposes and it is necessary to redimension the design from new datum. L. E. Farmer presented a theory for performing this change of datum, discussed a procedure for allocating tolerances to new dimensions and presented the procedure of change of datum as part of a computer aided design system. This paper deals with the development of the interactive computer program which is insufficiently presented without all coding list of program by L. E. Farmer.

This study aims to conduct a case study of the Science, Technology, Engineering, Arts, and Mathematics (STEAM) outreach program development and their application. This program was operated by 184 middle and high school students at C University on October 2014. The major results of these studies were as follows: First, The theme of the outreach program consisted of four engineering areas, aerospace engineering, chemical engineering, architectural engineering, and mechatronics (robot) engineering; moreover, the materials for the students' workbook, the guidebook for teachers, and the program operation manual for staffs in a university were developed by working with four authors and ten subject matter experts. Second, the satisfaction level with the contents and activities was ranged from 4.24-4.31 out of 5 points. Third, the vitalizing activation plan was discussed for the sustainable development and operation of the STEAM outreach program.

A CAD/CAM system has been developed for rapid prototyping (RP) of microfluidic devices based on excimer laser micromachining. The system comprises of two complementary softwares. One, the CAM tool, creates part programs from CAD models. The other, the Simulator Tool, uses a part program to generate the laser tool path and the 2D and 3D graphical representation of the machined microstructure. The CAM tool's algorithms use the 3D geometry of a microstructure, defined as an STL file exported from a CAD system, and process parameters (laser fluence, pulse repetition frequency, number of shots per area, wall angle), to automatically generate Numerical Control (NC) part programs for the machine controller. The performance of the system has been verified and demonstrated by machining a particle transportation device. The CAM tool simplifies part programming and replaces the tedious trial-and-error approach to creating programs. The simulator tool accepts manual or computer generated part programs, and displays the tool path and the machined structure. This enables error checking and editing of the program before machining, and development of programs for complex microstructures. Combined, the tools provide a user-friendly CAD/CAM system environment for rapid prototyping of microfluidic devices.

With rapidly changing modem information technology, the structure of our lifestyle has underwent much changes in our society. One of these changes is an immense distribution of computer desks, which became necessities of life in various organizations, companies and public offices as well as at home. Therefore, many companies are faced with the necessity of bringing about a new product with esthetic needs and new functions and come to have opportunities to make profits from top-quality products based on competitive design development. The academic design support program in collaboration with industry can provide design-related industry with a design assistance for a new product development, in addition, it can give to the professional faculty of the college the chances to contribute to advancement of design industry of the nation. To accomplish the need and purpose of this research, the design development of unified computer desks was carried out with the introduction of life-long Universal design concept named ‘Design For All.’ The theoretical background of this study researched all the literature on the terms definition of a computer desk, the concept and definition of Universal design and design support program in collaboration with industry and performed data analyses for a product development through an analysis of domestic products and a benchmarking of foreign products. On the basis of these theoretical background and analysis results, this research brought out a new product through designing processes and the information of this production could be utilized via the feedback of a new product. That is, this research was done for a practical use.

기술준비수준(TRL)은 미항공우주국(NASA)에서 1995년 처음 제안되었다. TRL의 정의는 하드웨어 및 소프트웨어 제품에 적합하도록 변형되어 사용되었다. 많은 국가 연구개발사업은 이와 유사한 평가기준을 가지고 있으나, 전문가의 개인적 역량에 따라 평가결과가 많은 영향을 받게 되며, 상대적으로 개발기술의 성능과 시작품의 신뢰성도 낮은 편이다. 본 연구의 목적은 부품소재사업에 TRL을 적용하는 것이다. 이를 위해서 부품소재사업에 적합한 TRL 개념을 정의하고, 기술 분야별로 세 가지로 나누어 구체적으로 다시 정의해 보았다. 이렇게 정의된 TRL 개념의 적용 가능성을 검토하기 위하여 2007년도 신규 제안서의 TRL을 평가하여 보았다. 이로부터, 부품소재사업 신청 과제들에 대한 TRL특성을 알 수 있었으며, TRL과 같은 객관적인 R&D사업 관리 요소 도입의 필요성을 인식할 수 있었다. 이를 위하여, 향후 기술 분류의 세분화를 통한 구체적인 TRL 판단기준을 개발하는 것이 중요한 요소이다.

In this paper, we performed the customization of CAE analysis in the process of product development and verification. The purpose of customized analysis is to implement collaboration framework of inter-corporate, inter-division for knowledge process based on product development. Customized analysis methodology using ANSYS Workbench API is presented for the web-based and workbench-based application. Cellular phone was selected as a CAD model, and template based process of analysis is conducted. By using this system, customized analysis is suitable to site or user oriented specific analysis and for user who has little experience on CAE analysis.

From 2010, an "excellent engineer" undergraduate and graduate program had been initiated in higher education of China to promote the development of industry and social economy. In this circumstance, the engineering education programs in Dalian Maritime University are reformed to satisfy the requirements of transportation industries. And the engineering practice, engineering activities, and engineering courses are emphasized. In this training program, industrial communities are deeply involved in the engineering education and training procedure; the students are educated and trained in university and enterprise according to the common standards and industrial standards; and the engineering competences and creative ability are emphasized and are to be enhanced in the training schedules and procedure. A joint-training mode has been established already between Dalian Maritime University and enterprises in transportation fields.
