Job-wage is "a compensation system in which the basic pay is determined by the value of the task regardless of the nature of the person performing the task." The retirement age of workers in 2016 is trying to improve the wage system due to the enactment of the 60-year-old law. The performance salary system introduced in the previous administration try to switch the government of Moon Jae-in. In other words, the introduction of performance salary from the Seniority based Wage and the shift to the job payment system are taking place. This study analyzed case agencies in connection with the transition of job wage to public agencies. In other words, based on the awareness of the employees involved to the contents of the transition of the performance annual salary system to the job wage system analyze empirically. This study finds that there was strong negative perception of the performance-based pay system as a whole and the shift to a job wage system was also highly opposing. It was revealed that efforts to improve the problem are needed to improve performance annual salary system, to reverse the negative perception of job wage, to prepare fair evaluation criteria for performance and job duty and to persuade employees who oppose job change.

Objectives: The Ministry of Employment and Labor's enforcement programs, such as workplace monitoring inspection, are one of the major public efforts to protect worker's health. Therefore, a more effective inspection method is required for workplace monitoring, which is helpful for controlling health hazards in the workplace. Methods: For this study, we investigated the related safety and health laws, regulations, and inspection guidelines from the USA, Japan, and Korea. We also analyzed the provisions of industrial safety and health acts, which are related to enhancing the reliability of workplace monitoring. We applied the process of opinion convergence through an experts meeting for our research. Results: We proposed an efficient inspection scheme for workplace monitoring that includes how to select companies(mainly randomized inspections by using a workplace measurement database and workers' compensation insurance database), how to proceed with the inspection process(mainly unannounced visits), and who should carry out this project. Conclusions: We conclude that our proposal for the inspection of workplace monitoring could be a very effective tool for reducing the numbers of companies that do not undertake workplace monitoring and could produce reliable monitoring results.

Purpose: This study aimed at improving the indoor environment of the office building by measuring the indoor environment and conducting a survey. Method: The measurement was conducted from January 13 to March 16 in 2012, targeting 44 sites in same office building located in Seoul, South Korea. The lists of measurement such as dry-blub temperature, relative humidity, formaldehyde (HCHO), asbestos, carbon monoxide (CO), carbon dioxide (CO2), volatile organic compounds (VOCs) and particle pollution (PM10) were measured. In addition, illuminance which belongs to light environment and noise in sound[acoustical] environment were measured respectively. Result: The buildings showed overall pleasant conditions. In terms of the thermal, air, sound, and visual environment, each measurements were satisfied with the requirements in standard, within pleasant ranges, except several sites. However, the survey results were revealed that the office workers were mostly dissatisfied with their indoor environment. Given that the measured values were mostly within standards, the results of survey might have resulted from a compensation mentality biased toward the subjects in psychological terms.

Inhaled inorganic dusts, such as coal, can cause inflammation and fibrosis in the lungs, known as pneumoconiosis. Diagnosis of pneumoconiosis depends on morphological changes by radiological findings and functional change by pulmonary function test (PFT). Unfortunately, current diagnostic findings are limited only to lung fibrosis, which is usually irreversibly progressive. Therefore, it is important that research on potential and prospective biomarkers for pneumoconiosis should be conducted prior to initiation of irreversible radiological or functional changes in the lungs. Analytical techniques using exhaled breath condensate (EBC) or exhaled gas are non-invasive methods for detection of various respiratory diseases. The objective of this study is to investigate the relationship between inflammatory biomarkers, such as EBC pH or fractional exhaled nitric oxide ($FE_{NO}$), and pneumoconiosis among 120 retired coal miners (41 controls and 79 pneumoconiosis patients). Levels of EBC pH and FENO did not show a statistically significant difference between the pneumoconiosis patient group and pneumoconiosis patients with small opacity classified by International Labor Organization (ILO) classification. The mean concentration of $FE_{NO}$ in the low percentage $FEV_1$ (< 80%) was lower than that in the high percentage (80% $\leq$) (p = 0.023). The mean concentration of $FE_{NO}$ in current smokers was lower than that in non smokers (never or past smokers) (p = 0.027). Although there was no statistical significance, the levels of $FE_{NO}$ in smokers tended to decrease, compared with non smokers, regardless of pneumoconiosis. In conclusion, there was no significant relationship between the level of EBC pH or $FE_{NO}$ and radiological findings or PFT. The effects between exhaled biomarkers and pneumoconiosis progression, such as decreasing PFT and exacerbation of radiological findings, should be monitored.
