According to the progress of national informatization throughout the world, infringement and threaten of privacy are happening in a variety of fields, so government is providing information security policy. In particular, South Korea has enhanced personal impact assessment based on the law of personal information protection law(2011). But it is not enough to effect the necessary cost calculation standards and changeable factors to effect PIA. That is, the budgets for PIA was calculated lower than the basic budget suggested by Ministry of Government Administration Home affairs(2011). Therefore, this study reviewed the cost calculation basis based on the literature review, cost basis of similar systems, and reports of PIA and obtained to the standard with Delphi analysis. As a result, the standards of PIA is consisted to the primary labors and is utilized to how the weights by division of target system, construction and operating costs of target system, type of target systems, etc. Thus, the results of this study tried to contribute to ensure the reliability of PIA as well as the transparency of the budget for privacy in public sector.

This study analyzed the effect of the operation system of human resource management. First, the primary operating direction of the goal, talent selection system, and personnel management personnel management affected almost all the performance variables. More than one primary goal of personnel management in the loyalty inspired workers more than the fixed labor costs, and external recruitment of short-term hiring favored internal training scheme for long-term employment, employee training, and development in the long term more than short-term performance improvement the more weight to quality and innovation in the productivity of labor, product and services, employee-driven innovation, reduce turnover, had a positive impact on labor relations. On the other hand, the primary goal of personnel management and personnel selection methods had a positive impact on financial performance. Personnel management operating direction did not significantly affect the financial results. Second, the main type of employee utilization affected the quality of products and services, and labor relations. Trying to take advantage of temporary workers more than regular workers had a positive impact on the quality of products and services, and labor relations. Third, the operating unit of Personnel Management had an impact on the degree of innovation of products and services. Both personal achievements and the performance of the operating units had a positive impact on the degree of innovation of products and services, more than teamwork and personnel management. This study provided practical implications for verifying the effect of detailed characteristics of human resource management on financial/non-financial business performance.

The purpose of this study is to analyze the impact of the financial performance of regional public hospitals on their efficiency. In addition, the analysis of their efficiency using environmental factors, such as the market share, operating mode, and size of the regional public hospitals, as well as the factors influencing their efficiency, are selected by selecting the input and output factors of the hospitals and some differences were found between them. The DEA index and financial performance of the 31 regional public hospitals were calculated for the three years from 2012 to 2014. ANOVA and hierarchical regression analysis were used. As a result, there was a significant difference in their efficiency according to the environmental factors, such as the city scale of the regional public hospital, the number of hospital beds, and their business performance, productivity, and publicness. The medical profit margin (p<0.05), labor cost investment efficiency (p<0.05) and HHI (p<0.05) were found to affect the efficiency. In order to identify the inefficiencies of the regional public hospitals and increase their efficiency, it is necessary to measure the efficiency of the input resources and to reduce their cost. In addition, if the regional public hospitals were to provide specialized services, such as specialized functions of medical care that would give them a competitive advantage over private hospitals, their operational efficiency would be enhanced and they would be able to fulfill their role as public medical institutions.

This paper compares the realities of the salary Peak Policy's status and management processes in Korea and Japan, with the aim of determining the development direction for Korea's salary Peak Policy's. Unlike Japan, which successfully achieved close cooperation between government, firms and workers in implementing the Retirement Age Extension Type salary Peak Policy, Korea experienced many problems due to lack of preparation. In order to rationally develop the salary Peak Policy, the government, firms, and workers must cooperate to increase the policy's efficiency via the following steps. First, gradually increase the proportion of retirement age extension. Second, career development that takes into account the various employment types, flexible working hours and aged workers. Third, development of training programs for senior citizen workers, as well as increasing support for changing of jobs and startups. Fourth, expansion of re-employment after retirement age and ways to make use of the skilled labor. Fifth, increasing work efficiency through bonuses and work evaluation that is specialized for aged workers. This paper argues that such measures are necessary for the co-existence of firms and workers, as well as for improving employment stability and labor market flexibility.

Since 1945, the periodical reforestation projects considered as the fundamental apparatus of the forest policy of the Government have been continuously carried out during last 40 years in Korea. As a result, some of the forests are ready to be harvested, especially in well-managed plantations as well as in the natural forests. This requires to pay more attention to harvesting the timber rather than planting trees. At the present, such timber harvesting operations such as cutting, felling, bucking, and skidding and yarding, particularly yarding operations in mountain areas with harsh terrains are in the most cases depend upon man power. However, the yarding operations should be more mechanized in the near future in Korea mainly because of the high cost of labour couppled with the lack of labour in forested areas. The Forest Work Training Center attached to the Forest Administration imported and tested the smallsized cable crane(K-300) with movable tower. The result of economic analysis of the yarding operation expenditures shows that the cable crane yarding costs more than the man yarding at the present time. As the labour cost will gradually increase and the efficiency of machine operation will improve, the results of the study indicates that the yarding operation by cable crane will be more cost-effective in the future.
