This paper outlines opportunities and challenges in the implementation of BPEL based WFMS(WorkFlow Management System) for the MES(Manufacturing Execution Systems) in semiconductor manufacturing. At present, the most MESs in semiconductor wafer fabrication shop have the problems in terms of application software integration, reactivity, and adaptability. When a plant has to produce new product mix, remodel the manufacturing execution process, or replace obsolete equipments, the principal road blocks for responding to new manufacturing environment are the difficulties in porting existing application software to new configurations. In this paper, the issues about WFMS technologies including BPEL standard applied for MES are presented. And then, we introduce the integrated development framework named nanoFlow which is optimized for developing the BPEL based WFMS application for automated manufacturing system. And we describe a WFMS implemented with using nanoFlow framework, review and evaluate the system.

For producing large numbers of professional nurses who could manage 21th century's human health, it is necessary to review the direction of registered nurses' national examination which evaluates the nursing education and is granted a licence. For adapting to social expectation of the nurse, we have to nurture the nurses' problem solving capability in clinical setting. Seven divisions of Korean Academy of Nursing suggested clinical competency according to their categories. This paper was presented in the work-shop for setting up direction of registered nurses' national examination. We expect that this paper would be more refine and confirm through reviewing subdivisions' learning objectives and discussing clinical minimum level of competence contents with clinical leaders.

Objective: This study aims to suggest different approaches in analyzing risks associated with musculoskeletal disorders (MSDS) for risk assessment. Background: Upon concluding that the changes in the industrial environments have made it hard to regulate diverse risk factors, the government has implemented a policy for risk assessment. Method: This study has proposed a method, creating programs using Excel that perform qualitative or quantitative analysis, for evaluating risk factors in risk assessments and has applied this in manufacture and service industries. Results: To verify the validity of the developed program, risk assessment has been performed on restaurant chefs as an example. For quantitative evaluation, the study has suggested approaches using the results for REBA evaluation and the analysis report on the work scenes of a fitting-shop in a shipbuilding industry. Application: Constructing and adapting a system using Excel in evaluating risk factors for risk assessments as this study suggests, is expected to contribute to revitalizing risk assessments.

The purpose of this study was to investigate women's indoor and outdoor everyday life including their housework, labor and leisure of the late Chosen period as expressed in paintings. Women's everyday life was classified into their indoor and outdoor life according to the custom of Naeoe, which had confined women's activities in the outdoors. This study analyzed 93 Paintings depicting the Due life of People. As a result, even though the Chosen period was a conservative society dominated by Confucian custom that confined women in the home, most women spent much of their time in the outdoors carrying water, washing clothes and doing farm work. Some common women participated in marketing household product, peddling and managing a drink shop. Especially, servant women such as Kineo, Muneo and Youneo labored in Public offices or Private Places. Consequently, this study suggests that the misconception should be corrected that traditional women's sex role had been confined exclusively in the home.

An automated manufacturing process mechanism for string musical instruments has been designed in this study. In contrast to other manufacturing products, classical string instruments try to preserve their traditional design shapes even in these days and involve variety of wood working(carpentry) characteristics including highly skilled curved surfaces treatments. Great efforts have been put to develop an integrated and automated system for improved product quality and process control, reduced physical labors, better safety etc. They, however, have been limited to devise jigs and tools with regard to selected processes due to lack of technology and research man-powers. We carefully examined the products and process characteristics, and an automated mechanism which overcome prevailing drawbacks has been derived.

In this paper, a determination method of number of AGVs fer introducing to the multi-path material handling systems is presented by using genetic algorithm. For serving the raw material to each work stations automatically, there needs to introduce a AGVs for transfer the raw martial. To reduce the overall production cost in the material handling systems, however, a trade off exists between the amount of inventory hold on the shop floor and the number of AGVs needed to provide adequate service. In this paper, firstly a objective function which included the net present fixed costs of each stations and each purchased AGVs, delivering cost. stock inventory cost, and safety stock inventory cost is presented. Secondly by using genetic algorithm, the optimal reorder quantity at each stations is decided, where the number of AGVs is increased step by step. From a simulation with different GA parameters, we can determine a optimal number of AGVs to reduce the overall production cost. Thus, the effectiveness of GA for determining the number of AGVs is verified in automated material handling systems.

Recently. AGV systems are used to serve the raw material to each work stations automatically. There exists a trade-off between the adequate service supply and the number of purchased AGVs. Also, to reduce the overall production cost, the amount of inventory hold on the shop floor should be considered. In this paper, we present a heuristic technique for determining the number of AGVs which includes the net present fixed costs of each station, each purchased AGV, delivering cost, stock inventory cost, and safety stock inventory cost. Secondly, by using a genetic algorithm, the optimal number of AGVs and the optimal reorder quantity at each station are decided. Lastly, to verify then heuristic algorithm, we have done a computer simulation with different GA parameters.

China's rapidly growing cities offer a unique opportunity to create highly sustainable communities. Architects and their clients, typically real estate developers, are highly focused on strategies that are effective at reducing energy and water usage at the scale of the individual building or within a master plan of multiple related buildings. However, a closer look at energy consumption reveals that transportation uses more energy worldwide than residential and commercial buildings combined. In light of this, it is appropriate that China is making massive investments in transportation infrastructure like heavy rail rapid transit and grade separated expressways, but the end result of these investments to date has been to enable people to live further from where they work and shop rather than closer - while simultaneously not creating walkable communities. Using positive and negative examples from Asia and the rest of the world, this article will investigate the specific urban design policies such as height limits, setbacks, land use restrictions, parking ratios, and parcel size which might change to enable the creation of truly sustainable communities for China's 21st century.
