  • This paper recommends to teach technical writing as a part of the curriculum of engineering design courses. Some features of both engineering design and keystone design course as well as capstone design course for engineering students are studied before the relationship of those features with written communication are investigated. After the characteristics of collaborative writing are reviewed, some aspects of integration of teaching technical writing into engineering design courses are evaluated. Technical writing for engineering students is best taught by collaborative writing approach in engineering design courses.

  • We have investigated printing techniques for processing organic light-emitting diodes (OLEDs). We succeeded to gravure print uniform organic thin films as well as screen print low work function cathode for OLED structure. Furthermore, by using roll-to-roll manufacturing methods, we have been able to fabricate all-printed flexible OLED demonstrator.

  • With speed-up of existing railway, a greater attention is paid to the riding safety and the comfort of the passengers. They are combined to some technical factors related to track such as alignment, derailment coefficient, and track bearing capacity, A quantitative analysis method for those technical factors is presented in this study. Calculating the allowable transit speed, the technical reviews of speed-up of Janghang-Line(Chunan∼Janghang) are conducted. And the alternatives for improving train speed in existing railway are proposed.

  • A newly designed magnetic annealing apparatus was used for the treatment of Fe-3%Si steels. With the help of this device, the effect of magnetic annealing on magnetostriction was studied in a wide spectrum of external elastic stresses. It was shown that magnetostriction properties of Fe-Si steels were improved in the compressed state through magnetic annealing, while those in the unstressed state or under tensiion were found to be practically unchanged.

  • 이 연구의 목적은 3 연속 사이클 교육과정과 통합 기술교육 클러스터를 기반으로 직업인을 양성하는 이집트의 직업교육 학제를 탐색함으로써 한국 직업교육 체제에 시사점을 제안하는 것이다. 이집트의 직업교육은 진학을 목적으로 하는 일반 보통교육과 노동시장 입직을 목적으로 하는 직업교육의 학제가 이원화되어 운영된다는 점에서 한국의 학제와 체제는 유사하다. 그러나, 중등 직업교육, 고등 직업교육, 대학 수준의 고급 기술교육을 통합한 3연속 사이클 교육과정을 운영하고, 이러한 교육과정 운영의 효과성을 높이기 위해 동일한 물리적 공간에 집적된 통합 기술교육 클러스터를 활용하며, 일부 유럽 국가들과 협력시스템을 구축하여 직업교육의 품질을 관리하는 점 등에서는 차이가 있다. 본 연구 분석을 통해 이집트의 직업교육 학제를 구체적으로 제시하고, 한국 직업교육의 질적 제고를 위한 다양한 혁신방안들을 제안하였다.

  • This article presents a new generation of empirical ground motion models for the prediction of response spectral accelerations in soil conditions, specifically developed for the Vrancea intermediate-depth seismic source. The strong ground motion database from which the ground motion prediction model is derived consists of over 800 horizontal components of acceleration recorded from nine Vrancea intermediate-depth seismic events as well as from other seventeen intermediate-depth earthquakes produced in other seismically active regions in the world. Among the main features of the new ground motion model are the prediction of spectral ordinates values (besides the prediction of the peak ground acceleration), the extension of the magnitudes range applicability, the use of consistent metrics (epicentral distance) for this type of seismic source, the extension of the distance range applicability to 300 km, the partition of total standard deviation in intra- and inter-event standard deviations and the use of a national strong ground motion database more than two times larger than in the previous studies. The results suggest that this model is an improvement of the previous generation of ground motion prediction models and can be properly employed in the analysis of the seismic hazard of Romania.

  • The purpose of this study is 1) to research how practitioners in fashion industry in South Korea perceive concepts of Technical Design/Designer, 2) to compare and analyze issues at work by occupation, 3) to research specific works in garment development process, and 4) to compare and analyze work involvement by occupation, type of a company and etc, and 5) to propose the role of Technical Designers in apparel companies in South Korea. There were two methods to conduct this study, which were in-depth interview and survey. Both methods were conducted to designers, merchandisers, pattern makers, technical designers, and production coordinators. Frequency analysis, ANOVA, Duncan test, and Factor analysis were performed to get results by using SPSS 18.0 program. The results are following. There were 50 works during garment development process from the result of in-depth interview, and 6 factors were obtained from the result of Factor analysis, which were 'Works about Sample in Sample Development Process', 'Works about Product's Pattern and Size Spec', 'Works about Development of Garment's Design', 'Works about Planning of Product Development and Management of Product in Stock', 'Works about Production Process', and 'Preparation Works for Sample Development'. In conclusion, technical designer in apparel companies in South Korea should be in charge of works about sample in sample development process and decision making of product' size spec, which is included in works about product's pattern and size spec. Also, they should complete technical package after product is developed by designers.
