Objectives: The purpose of this study was to investigate whether there were differences in manufacturing industry worker's health issues depending on job stress, fatigue, and health and safety services. Methods: The purpose of the questionnaire survey and its contents were explained to manufacturing industry health personnel, and the questionnaires were collected from 666 workers from 17 manufacturing workplaces. Questionnaires with missing data were excluded from the analysis so a total of 632 questionnaires were included. Results: Overall, 74.1% of the respondents had experienced health issues during the preceding month. The factors affecting worker health were number of workers(OR=1.000034, p=.013), job demand(OR=1.82, p=.009), MFS(OR=1.85, p=.003), provision of safety & health information(OR=1.85, p=.048), wearing protector(OR=2.58, p=.021). Conclusion: It is necessary to strengthen the safety and health education to mitigate hazardous and risk factors. Employers should provide health managers in charge of safety and health education to control workplace risk factors. In case of small businesses, it may be necessary to strengthen safety and health education in existing worker health centers and government support projects.

Entrepreneurship is a creation of new combinations of goods and services. Today, every aspect of business operations has been changing, which we call development. The conventional business included production and manufacturing of goods and serving things the customer needed. Today, the business has changed form so that the demands of customers are shaped by the good or service which has been created by the businesses. Entrepreneurship in Mongolia is not a new concept but nowadays the number of entrepreneurs in Mongolia has grown sharply. Mongolia was a nomadic culture during its history and is probably the only nomadic culture left in the world today. Mongolian herders are the largest and the most powerful representation of successful entrepreneurs in Mongolia. Another practice of herders in the world are in Australia. Along with a comparison of the policy and government support system of Australia, this study intends to assess how 6 factors of the entrepreneurial ecosystem fit herders in Mongolia. As a result of this assessment, we propose policy to support the entrepreneurial mechanism of herders and identify cultural factors which support the existence of herding.

With the improvement of the Information Technology and the change of the business environment, the dependency of business on the Information Technology shows sharply increase. The Information Technology, however, is centered on the support of the technology viewpoint and thus the influence and effect of Information Technology on the business is hardly analyzed. The information system, therefore, requires not only technology-centric support management but service-oriented and systematic introduction of Information Technology Service Management(ITSM). The domestic ITSM market is currently expanding into variety of industries like finance, telecommunication, manufacturing and public service and at the same time the consequent reconstruction process of information system is continuously under way so as to qualify for the ISO 20000 certification. Especially the public organizations rapidly adopt the ITSM, in order to improve the quality of public service together with a goal of realizing the electronic government and of managerial innovation. The existing ITSM still, however, shows the tendency of depending only on the system construction and the management on the visible requirements whereas the overall process is not likely being improved. Hence, this study suggests, focusing on the life cycle of service, the model of ITSM based on Information Technology Infrastructure Library(ITIL) v3 which is appropriate for the public service. We expect, as stated in this study, that our ITSM model shall be widely accepted to the public agencies who promote the advance campaign by setting up the ITSM or reconstructing the existing process.

Facility layout problems (FLP) are usually treated as design problems. Lack of systematic and objective tools to compare design alternatives results in decision-making to be dominated by the experiences or preferences of designers or managers. To increase objectivity and effectiveness of decision-making in facility layout selections, a decision support model is necessary. We proposed a decision model, which regards the FLP as a multi-attribute decision making (MADM) problem. We identify sets of attributes crucial to layout selections, quantitative indices for attributes, and methods of ranking alternatives. For a requested facility layout design, many alternatives could be developed. The enormous alternatives, various attributes, and comparison of assigned qualitative values to each attribute, form a complicated decision problem. To treat facility layout selection problems as a MADM problem, we used the linear assignment method to rank before selecting those high ranks as candidates. We modelled the application of the Nemawashi process to simulate the group decision-making procedure and help efficiently achieve agreement. The electronics manufacturing service (EMS) industry has frequent and costly facility layout modifications. Our models are helpful to them. We use an electronics manufacturing service company to illustrate the decision-making process of our models.

RFID has fundamental influences on today's business management. This research seeks to formulate the opportunities and challenges, the strengths and weaknesses and the perceived benefits of RFID implementation in three industries: manufacturing, medical-service, and distribution. Ten companies of successful RFID deployment in Korea are presented. Field interview and panel discussion were used to explore the research purpose. The core challenges include RFID readability issues, lack of best practices, increasing prime cost, visible ROI, implementation cost, and employee's resistance. The strengths include IT infrastructure, system integration competency, RFID business model creation ability, executive's support. There is little weakness in Korea companies, there are many perceived benefits in three industries. The most distinctive finding is that the visible ROI was found out in the manufacturing industry, not in the distribution industry. The opportunities and challenges, the strengths and weaknesses and the perceived benefits are some different in three industries, which provide valuable guidance for Korean companies in seeking the RFID opportunities. This case study represents a pioneer research of RFID adoption in Korea.

Data Warehouses integrate data from multiple heterogeneous information sources and transform them into a multidimensional representation for decision support applications. Data warehousing has emerged as one of the most powerful tools in delivering information to users. Most previous researches have focused on marketing, customer service, financing, and insurance industry. Further, relatively less research has been done on data warehouse systems in the complex manufacturing industry such as ship production, which is characterized complex product structures and production processes. In the ship production, data warehouse systems is a requisite for effective cost analysis because collecting and analysis of diverse and large of cost-related(material/production cost, productivity) data in its operational systems, was becoming increasingly cumbersome and time consuming. This paper proposes architecture of the data warehouse systems to support cost analysis in the ship production. Also, in order to illustrate the usefulness of the proposed architecture, the prototype system is designed and implemented with the object of the enterprise of producing a large-scale ship.

The present research aims to examine whether learning from the supervisor influences readiness for change with the mediating impact of planfulness. Drawing upon the theory of planned behavior, it is hypothesized that learning from the supervisor positively impacts planfulness ability in individuals, which in turn enhances the readiness for change. Through using convenience sampling, the sample of 451 was collected from employees working full-time in the manufacturing and I.T. service organizations in India. Structural equation modeling and regression analysis indicate that learning from the supervisor is positively associated with readiness for change and planfulness. Additionally, planfulness fully mediated the relationship between learning from the supervisor and readiness to change. The findings of the present research highlight that continuous support and learning from the supervisor enhances the planfulness ability of the individual and consequently enhances individual readiness for change. The current research is pioneering in testing the hypothetical model associating learning from the supervisor, planfulness, and readiness for change.
