It is well known that ISO 9001 and TQM have significant effects on business success. We analyzed the effects of ISO 9001 requirements and TQM on financial performance with structural equation modeling. Hypotheses are proposed and tested based on existing beliefs, proposition and prior research concerning quality. Survey data were collected from 291 manufacturing companies with ISO 9001 certifications. The data show that ISO 9001:2008 requirements have significant positive direct effects on TQM practices, but do not have positive direct effects on financial performance. As expected, TQM has significant positive direct effects on financial performance. One of the important results is that efforts to meet ISO 9001:2008 requirements enhance TQM practices which, in turn, helps to improve financial performance. Findings in this study support the claims that ISO 9001:2008 would be a good step toward total quality management and is a meaningful component of TQM.

Background: A group health service is a system that delegates workplace health management to an entrusted institution. There have been various studies on group health services to date, but recent changes, such as an increase in foreign workers, are rapidly changing industry characteristics. Methods: Satisfaction was assessed using a 27-question survey distributed among 203 workplaces employing health professionals. The survey items consisted of general characteristics, comprehensive satisfaction, requirements for health professionals' work, and satisfaction with work environment management, ergonomic management, and healthcare management. Multiple regression and frequency analyses were performed. Results: The comprehensive satisfaction was 4.08 points on average, out of 5. The comprehensive satisfaction of health professionals in the industry was positively correlated with each factor. Hazardous materials and chemical management (material safety data sheets, MSDSs) were the most common requirements. Conclusion: A low level of satisfaction with work environment management indicates high demand for healthcare management. The working environment should be improved by identifying characteristics of the workplace, examining harmful substances, inspecting equipment, and enhancing worker methods. The shorter the work experience of health professionals, the more dependent they are on group health services. The variables affecting comprehensive satisfaction were the period of work, healthcare management satisfaction, and work environment management satisfaction. Most of the requirements of health professionals in the workplace were practical improvement case presentations, MSDSs, and legal document management.

In order to manage essential parts that are required for the repairable parts services performed at the military maintenance depots, the United States Air Force developed the Repairability Forecasting Model (RFM). In the RFM, if the requirements of the parts are assumed to follow the normal probability distribution after applying means from the past data to the replacement rate and lead times, the chance of the AWP (Awaiting Parts) occurring is 50%. In this study, to counter the uncertainties of requirements and lead times from the RFM, the safety level concept is considered. To obtain the safety level for requirements, the binomial probability distribution is applied, while the safety level for lead time is obtained by applying the normal probability distribution. After adding this concept, the improved RFM is renamed as the ARFM (Advanced RFM), and by conducting the numerical stimulation, the effectiveness of the ARFM, minimizing the occurrence of the AWP, is shown by increasing the efficiency of the maintenance process and the operating rate of the weapon system.

Objectives: This study was established to ascertain the requirements and implementation of core competencies for employees of the a workers' health center. Methods: The study consisted of a four-step process: a literature review, focus group interviews, expert opinions, and a questionnaire. The survey was conducted online among 119 employees of the National Workers' Health Center. Results: As a result of the research, eleven core competencies and 37 sub-competencies were derived in three areas: Competence as a social worker, competence to perform duties, and competence for maintaining expertise. The key demands for core competencies were "health consultation" and "understanding of small businesses.". They responded that they needed to "maintain an ethical attitude" and "consult on workers' health.". The largest score difference between core competency requirements and competency implementation was "collaboration with the community.". Conclusions: It is necessary to increase competencies not only for competencies with high core requirements, but also for relatively low competencies. In addition, efforts should be made to improve the core competencies of the employees of the Workers' Health Center to effectively respond to changes in the industrial structure and crises such as COVID-19.

As the first step of risk management, risk identification is inevitable to understand the degree of work safety. However, the safety requirements can be divided in necessary factors and additional factors. Thus, we propose a safety requirements assessment model using Kano model derived from Herzberg's two-factor theory, classifying safety requirements into ideal elements and must-be elements. The Kano model is usually applied to evaluate customer satisfaction divided into three major requirements in the fields of product development and marketing: attractive, must-be, and one-dimensional requirements. Among them, attractive requirement and must-be requirement are matched with ideal element and must-be element for safety requirement classification, respectively. The ideal element is defined as preventive safety elements to make systems more safe and the must-be element is referred to as fatal elements to be essentially eliminated in systems. Also, coefficients of safety measurement and safety prevention are developed to classify different class of safety requirements. The positioning map is finally visualized in terms of both coefficients to compare the different features. Consequently, the proposed model enables safety managers to make a decision between safety measurement and prevention.
