One of the objectives of any task design is to provide a safe and helpful workplace for the employees. The safety and health module may include means for confronting the design with safety and health regulations and standards as well as tools for obstacles and collisions detection (such as error models and simulators), Virtual Reality is a leading edge technology which has only very recently become available on platforms and at prices accessible to the majority of simulation engineers. The design of an automated manufacturing system is a complicated, multidisciplinary task that requires involvement of several specialists. In this paper, a design procedure that facilitates the safety and ergonomic considerations of an automated manufacturing system are described. The procedure consists of the following major steps. Data collection and analysis of the data, creation of a three-dimensional simulation model of the work environment, simulation for safety analysis and risk assessment, development of safety solutions, selection of the preferred solutions, implementation of the selected solutions, reporting, and training. When improving the safety of an existing system the three-dimensional simulation model helps the designer to perceive the work from operators point of view objectively and safely without the exposure to hazards of the actual system.

This study was limited Gangwon-do's manufacturing companies that participated in the educational-industrial consortium. These companies' present status and activities under implementation identified and interpreted by this study, therefore, are insufficient to be generalized into knowledge applicable to most of the companies in Gangwon-do. For more precise and detailed results, it is suggested to make further studies that cover not only those consortium companies but also non-consortium manufacturing companies in Gangwon-do. The results also suggest that it is necessary to promote some periodic manpower training programs in cooperation with local universities, to utilize professors and experts to build management strategies that can bring and secure the power of competition, and to construct a system of educational-industrial cooperation, as ways leading these companies to the 21 st century's type of business enterprise.

As part of an effort to systematize the operation planning for cutting processes, the neural network method has been applied to model the process of selecting cutting conditions and subsequently to arrive at effective and safe cutting conditions through learning during training of the model. New cutting conditions that are more effective and safer for the given circumstance are obtained. The proposed algorithm deletes the old information previously learned, and then makes the network make at improvement by learning. As a result, the new algorithm provides useful cutting conditions for safer manufacturing environments. A variety of simulation cases illustrate the performance of the proposed methodology. The simulation results are provided and discussed.

When newcomer countries consider a nuclear power programme, it is recognized that the most important organizations are the Nuclear Energy Programme Implementing Organization (NEPIO), the regulator, and an operating organization. Concerning the number of construction delays these days, one of the essential organizations is an Authorized Inspection Agency (AIA). According to World Nuclear Industry Status Report, all of the reactors under construction in eight out of the thirteen countries have experienced delays. Globally, the Flamanville 3 project and Sanmen Unit 1 are 6.5 years and 5 years late respectively. One of the major reasons of delay is due to inappropriate manufacturing and inspection on safety class components. The recommendations are made to develop such an organization: (i) find existing inspection organizations in relevant industries, (ii) contract with expatriates who have experience on nuclear inspection, (iii) develop a legislative framework to authorize the inspection organization with enforcement, (iv) include a contract clause in the BIS for developing the AIA, (v) hold training programmes from vendor country, (vi) during manufacturing and construction, domestic AIA shall be involved.

This study is to propose an 'education-training-certificate of qualification' design of fashion accessories production, which can be applied to education in universities and individuals. It is based on the National Competency Standards (NCS), which was developed through the '2013 National Competency Standards Development Project' for the fashion accessories production. FGI (Focus Group Interviews), which is a research methodology, is carried out on target groups of educational experts and specialists in the field of fashion accessories production. Through this, five courses were suggested; first, 'fashion accessories design' course was proposed for the education and training of 'design development' and 'development of raw materials'. Secondly, 'fashion product production' course was proposed for the education and training of 'production of samples'. Thirdly, 'fashion product manufacture and planning' course was proposed for the competency element units: 'calculation of cost', 'determination of mass production model and price', 'planning of the main manufacturing process' and 'ordering of raw materials'. Lastly, 'mass production of fashion products' course and the 'field practice of fashion product manufacture' course were proposed for the competency element units: 'planning for mass production', 'preparation for mass production', 'mass production' and 'inspection of completed products'. In addition, a new certificate of 'technician of fashion accessory production' was proposed in order to test qualified skills for the fashion accessories production. The test is composed of a written examination of short-answer questions, technical drawing and production.

During the past decade, there were many well-established theories for the adaptive control of linear systems, but there exists relatively little general theory for the adaptive control of nonlinear systems. Adaptive control technique is essential for providing a stable and robust performance for application of industrial robot control. Neural network computing methods provide one approach to the development of adaptive and learning behavior in robotic system for manufacturing. Computational neural networks have been demonstrated which exhibit capabilities for supervised learning, matching, and generalization for problems on an experimental scale. Supervised learning could improve the efficiency of training and development of robotic systems. In this paper, a new scheme of adaptive-neuro control system to implement real-time control of robot manipulator using digital signal processors is proposed. Digital signal processors, DSPs, are micro-processors that are developed particularly for fast numerical computations involving sums and products of variables. The proposed neuro control algorithm is one of learning a model based error back-propagation scheme using Lyapunov stability analysis method. The proposed adaptive-neuro control scheme is illustrated to be an efficient control scheme for implementation of real-time control for SCARA robot with four-axes by experiment.
