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 this paper, we present the DEA (Data Envelopment Analysis) application case study to investigate the regionally distinctive telco management characteristics of the Asia-Pacific countries. This study attempts to exploit the implications of DEA for the assessments of core process capabilities of telcos. Accordingly, we extract input variables of CAPEX (capital expenditure), operating expense, marketing expense, and number of employees, each to reflect the competitiveness of the core processes such as fixed asset utilization, operation & sales efficiency, and white collar productivity. In conjunction with the input variables, the output variables are chosen as EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization), ARPU (Average Revenue per User), and number of subscribers. The computational testing results, conducted with total 37 telcos of the 12 Asia-Pacific countries, are analyzed in various ways to understand the distinctive performance characteristics across the region. The managerial implication captured from this study provides useful insight for using DEA as the international telco management purpose.

The characteristics of agricultural water rights were examined for the national rivers in Korea. We suggest that the national rivers could according to the actual management organization of agricultural water right be categorized into national management rivers KOWACO(Korea Agrcultural & Rural Infrastructure COrporation) management river. The agricultural water right between the national and KOWACO management rivers have different characteristics for irrigation period permit procedure water charge and type of water right. The agricultural water rights are granted in the natural discharge less than reference droughty discharge for most of national management rivers and in the developed discharge for the KOWACO and KARICO management rivers. The current system of agricultural water rights is complicated inconsistent and incapable of coping with unusual drought and therefore it needs to be improved.

The purpose of this study includes: the relationships between job characteristics and service quality and the mediating effect of the psychological ownership on the relationship between job characteristics and service quality. In order to verify the relationships and mediating effect, data were collected from 255 nurses in a university hospital at Ulsan city to test theoretical model and its hypotheses. All data collected from the survey were analyzed using with SPSS 18.0. and AMOS 18.0. This study reports findings as follows: first, the relationship between the job characteristics and the psychological ownership is positively related. Second, there was also a positive correlation between the psychological ownership and service quality. Third, the relationship between the job characteristics and the service quality is positively related. Finally, the psychological ownership played as a partial mediator on the relationship between job characteristics and service quality. Based on these findings, the implications and the limitations of the study were presented including some directions for future studies.
