Process Capability ($C_{pk}$) is a representative measure of how well the producer manages dispersion and bias for the specifications needed by the consumer. This is expressed as a ratio of 6 times the natural tolerance to the specification. As the producer manages the dispersion small, the capacity index becomes higher. And it is classified into 5 grades according to the degree of management. It is a measure of the quality of processes used in most industrial fields. However, $C_{pk}$ is calculated by only reflecting the mean and dispersion of the process, there is a disadvantage that it can not give information about the economic loss caused by the inconsistency of the process with the target value. Overcoming these drawbacks, process capability indexes reflecting various types of loss functions such as $C_{pm}$, $C^+_{pm}$ and $C_{pl}$ have been developed. However, all of these previous studies have applied the limit to the consumer specification, which is based on the traditional and passive quality perception that the quality characteristic should exist within the limits of the consumer specification. In this study, we will develop 'Customer Satisfaction Quality Indicator (CSQI)' which is a quantitative indicator that can be fully evaluated when the manufacturer's specification limit, which is an aggressive quality strategy, is applied. This is expected to be useful decision information for both producers and consumers.

Background: This study aimed to prioritize policy measures to improve radiation safety management in medical institutions using the analytic hierarchy process. Materials and Methods: It adopted three policy options-engineering, education, and enforcement-to categorize safety management measures, the so-called Harvey's 3Es. Then, the radiation safety management measures obtained from the current system and other studies were organized into action plan categories. Using the derived model, this study surveyed 33 stakeholders of radiation safety management in medical institutions and analyzed the importance of each measure. Results and Discussion: As a result, these stakeholders generally identified enforcement as the most important factor for improving the safety management system. The study also found that radiation safety officers and medical physicists perceived different measures as important, indicating clear differences in opinions among stakeholders, especially in improving quality assurance in radiation therapy. Hence, the process of coordination and consensus is likely to be critical in improving the radiation safety management system. Conclusion: Stakeholders in the medical field consider enforcement as the most critical factor in improving their safety management systems. Specifically, the most crucial among the six specific action plans was the "reinforcement of the organization and workforce for safety management," with a relative importance of 25.7%.

In this study, we attempt to provide empirical evidence for the effect of the expenditure of the local governments on the air quality management. Based on the statistical data, the concentrations of air pollutants including $PM_{10}$, $O_3$, and $NO_2$ were analyzed in accordance with local characteristics of the local governments' environmental expenditure, demographic characteristics, and economic and human resources between 2008 and 2014. The results showed that government spending is estimated to have insignificant impact on air pollutants concentration. All these results are consistently corroborated from the analysis based on different alternative measure of local governments' expenditure (budget composition and measure of expenditure residuals). Subsequently, this study implies that environmental expenditures of local governments have not been effectively enforced to enhance the air quality of the region in Korea.

This study aims to estimate the consumption of antibiotics in Korea and to suggest the further studies. To measure the amount of antibiotics consumption, we referred to the statistic of NFHI(National Federation of Health Insurance) and a private institute of pharmaceutical information(Korea Intercontinental Medical Statistics; IMS Korea). There were 1,563 antibiotics produced in Korea in 1997. The total amount of antibiotics production was 1,197 billion won in 1997. Antibiotics accounted for 17.6% of the total pharmaceutical productions in 1997. Cephalosporins have taken the largest part of antibiotics production since 1992. The estimation using NFHI data showed that the total expenditure of antibiotics used in health facilities was 268 billion won, 608 billion won, 911 billion won in 1990, 1994, 1997 respectively. Tertiary hospitals spent 246 billion won, general hospitals 287 billion won, hospitals 78 billion won, clinics 300 billion won in 1997. The amount of expenditure and the intensity of antibiotics consumption in hospitals have increased more steeply than any other health facilities. The total expenditure of antibiotics consumption in health facilities and pharmacies was 778 billion won when estimated using the data from IMS Korea, and 999 billion won from NFHI. Cephalosporins was the fast growing antibiotics group in all of the market- hospitals, clinics, pharmacies since 1991. To measure the amount and patterns of antibiotics consumption more precisely, a pharmaceutical monitoring or surveillance system is needed.

Currently the forest area is 6,370,000 hectare (ha) which occupies 63.7% in Korea. The forest has good functions such as production of forest products, conservation of national land, prevention of disasters, etc. However constructing houses near the forest area make bad situation like illegal waste incineration by resident. So research subject is forest fire caused by waste incineration place including facility. And this study was conducted about statistical analysis and research analysis of the 100 waste incineration places including facilities at the country town. Statistical analysis shows that March is 27% which percentage is the highest number of forest fire in 10 years' average. The number of forest fire caused by waste incineration is 45 which is the third highest number in the fire statistic. The distance between waste incineration place including facility and forest area is 30m, 40m and 50m. That 40m (36%) is the most common distance from forest area. The types of waste incineration are ground (62%), the temporary facility made with oil drum can (35%) and other made with steel sheet, concrete, etc. The result of this study is that government and local government must conduct the improvement measure to reduce illegal incineration such as waste pickup area made with rain and wind proof type installed near residence, expenses for waste treatment, enlightenment and training, etc. Also considering their age and income are needed for realistic improvement.

Robot-based layout automation has been recently promoted for the purpose of improving productivity and quality. Marking robots have various functional demands to secure marking precision and environmental adaptability. In particular, in order to automate marking work of building structure, correction of the marking line through position recognition of rebars placed is required. Because the rebars must maintain a constant cover thickness from the formwork surface, if the rebars are out of planned position, the rebar or marking line need to be corrected to secure the cover thickness. Thus, the marking robot for structural work needs to have the function for determining the position correction of the rebar or the marking line. In order to judge the correction of marking line, it is required to measure the distance between the planned marking line and the rebar placed. Therefore, this study proposes an algorithm that can measure the distance between the planned line and the rebar, and correct marking line for the automatic operation of the marking robot. The results of this study will be utilized as a core function for unmanned operation of the marking robot and contribute to securing precise marking by reflecting construction errors.

Purpose - This paper examined the relation between Correction of Annual Reports and Earnings management. The annual reports are used as key reports for critical decision making by providing useful information to various stakeholders across the firm. Design/methodology/approach - The sequence of this study is analysed that each of the following two cases affects the earning management: 1. that corrections have been made; 2. Where financial information have been modified or non-financial information have been modified during the correction of the annual report. We draw an initial sample of firms listed on the Korea Stock Exchange from 2014 to 2017. Among these, we excluded firms that were not able to obtain the variables needed to measure the correction of Annual Reports and the earnings management. Finally, we use the 7,035 firm-year observations. Findings - Our empirical results of this study are as follows; First, it turned out that the earnings management of companies that report business reports on corrections is larger than those that do not. Second, among the types of annual report corrections, the correction of non-financial information is significantly larger on earnings management than the correction of financial information. Research implications or Originality - The correction disclosure of business reports is a very important issue in terms of accounting information accuracy and reliability. The results of this study will provide policy implications for correction disclosures and regulations due to an important issue as accounting information. An entity that initially prepares accounting information should advanced in such a way that it provides high quality accounting information and then complements and accepts it by various stakeholders.
