본 고는 공학적 안전설비 작동계통 보조계전기 캐비넷의 설계과정을 위하여 작성되었다. 공학적 안전설비 작동계통 설계는 순차적인 과정을 밟아서 진행이 되므로, 설계담당자(Cognizant Engineer)는 그 작업순서를 이해하여야 하며, 각 과정마다 필요한 자료들과 생산해야될 결과물들을 정확히 파악하여야만 설계가 원활히 수행될 수 있다. 또한, 설계과정은 많은 연계 업무가 있으므로, 서로 주고받아야 할 자료들의 종류 및 그 시기를 예상할 수 있어야 한다. 그리하여, 본 내용에서는 공학적 안전설비 작동계통 보조전기 캐비넷의 특성에 따라 연계요건서, 설계시방서 및 개념적인 도면을 중심적으로 기술하였으며, 기기설계(Component Design)와 제작설계(Manufacturing Engineering) 및 현장지원(Field Supports)은 아직까지도 미비한 점이 많으나, 담당자(Cognizant Engineer)가 아는 바대로 작성하였다.

Though the history of finite element analysis in field of powder metallurgy is not short, industrial engineer is still being dependent on the trial and error approach based on engineer's experience in selecting process conditions. This problem is mainly due to the difficulty in establishing models for the behavior of a powder compact during compaction and sintering as well as finding material parameters for the models and the absence of CAE software with which industrial engineer can easily investigate the effect of process conditions on the quality of product. Therefore, we established very simple and cheap procedure to find material parameters for powder compaction behavior and implemented it in self-developed commercial CAE software for powder metallurgy, PMsolver. Basically, the development strategy of PMsolver lies on simplification and convenience so as for industrial engineers to use it with least training. Using PMsolver, optimal process conditions were found for some geometry and powders. Prior to process condition design, the accuracy of finite element analysis was verified.

New national certified license tests for the facility management of new and renewable energy is given from this year. There are three national certified licenses including craftsman, industrial engineer and engineer. The subjects for the craftsman are photovoltaic facility for written exam and practical business of photovoltaic facility for writing exam. The subjects for the industrial engineer are theory, construction, management and law of the photovoltaic system for written exam and practical business of photovoltaic system for writing exam. The subjects for the engineer add one more subject compared with the industrial engineer, such as design of photovoltaic system. The first tests were given in september 28 in this year. The tests will be given three in 2014.

The role of the Engineer in the era of nano-technology is explored, a trend in manufacture which is expected to yield a ＄20-30 billion per annum business throughout the world by the year 2020. The engineers who will be working in this subject will be required to have broadly based experience, over a range of traditional disciplines, such as physics. electronics, software engineering, control and mechanical engineering. As well as having an appreciation of other disciplines such as air conditioning, vibration analysis and its minimisation, the selection of materials for maximum stability and minimal thermal distortion as well as an understanding of ultra precision design and nano tribology. In other words the engineer who is to be successful in this new and emerging field, will have to be broader based than engineers of the past, where it was traditional to break up the elements of a discipline to smaller subsets. But as nano-technology advances and the subject brings about the evolution of nanotronics to provide a successful solution to emerging problems, it will be essential for a breed of engineers to develop who can consider the subject in a holistic manner. This paper therefore considers the emergence of nano-technology, predicts the subsets of the development and places them in context of the new engineer which will be required in increasing numbers. The paper summarises the skills of the proposed nanotronics engineer and provides a basis for their training and development.

Concern for noise problems of a commercial aircraft in community and cabin is increasing due to the more restrictive regulation and customer requirements. This paper introduces to the work packages of the aircraft noise engineer for the development of a commercial aircraft. First of all, the noise engineer establish the design requirement and objectives(DR&O). Then the design and analysis are performed to satisfy with the DR&O during the conceptual and preliminary design phase. And the test and evaluation(T&E) are carried out to verify the analysis results and to acquire the type certification.
