Prolonged in-plant personnel exposure to high noise levels results in permant hearing damage. There are no way to correct this hearing damage by treatment or use of hearing aids. Therefore, every employer is responsible for providing a workplace free of such hazards as excessive noise. This study was carried out to evalute and predict a given noise environment based on specific limit as the noise guarantee for a newly-founded petrochemical plant. The maximum total sound level should not exceed 85dBA in the work area, except where the area is defined as a restricted area and 70dBA at the plant boundary. Prediction of the noise levels within the plant area for a newly-founded petrochemical plant was achieved by dividing all plant area into 20m$\times$20m regular grid spaces and noise level inside the area or unit that in-plant personel exposure to high noise levels was estimated computed into 5m$\times$5m regular grid spaces. The noise level at the grid point that was propagated from each of the noise sources(equipments) computed using the methematical formula was defined as follows : $SPL_2$=$SPL_1-20log{\frac{r_2}{r_1}}$(dB) where $SPL_1$ =sound pressure level at distance $r_1$ from the source $SPL_2$=sound pressure level at distance $r_2$ from the source As a result, the equipments exceeded noise limit or irritaring noise levels were identified on the specific grid coordinates. As for equipments in the area that show high noise levels, appropriate counter-measures for noise control (by barriers, enclosure, silencers, or the change of equipments, for example) should be reviewed. Methods for identifying sources of noise applied in this study should be the model for prediction of the noise levels for any newly-founded plant.

Background: Since the Republic of Korea became a labor-force-importing country, the number of foreign workers has increased gradually, especially in the construction industry. The main objective of this study was to examine the differences in safety perception between domestic and foreign workers at Korean construction sites. Methods: A total of 891 Korean and foreign workers were surveyed: 140 foreign and 751 Korean workers. The general characteristics and 25 factors influencing safety perception were considered in the questionnaire. Regression and correlation analyses were conducted to examine the variables of workers' safety perception. Results: Differences of nationality (F = 7.379, p < 0.001) and workplace accidents were statistically significant for both domestic (F = 1.503, p < 0.05) and foreign workers (F = 7.868, p < 0.05). In contrast, age, education, and Korean language level were significant variables only for foreign workers. Correlation coefficients of $0.428^{**}$ for Korean and 0.148 for foreign workers between two items - namely, "management's commitment to safety" and "blaming staff when they make mistakes" - support the conclusion that foreign workers do not trust management's commitment to safety, while Korean workers have confidence in these commitments. Conclusion: Foreign workers' level of safety perception should rise to the same level as Korean workers, especially in terms of obeying safety rules, safety education performance, and safety beliefs. Therefore, an improvement plan for the Korean construction industry is suggested in order to have a better safety level at construction sites with foreign workers.

Recently as the reports on toxicity of some nanomaterials and the nanoproducts containing these nanomaterials are rapidly increasing, the safety management issues about nanomaterials and nanoproducts are emerging hot. Especially safety in the workplace and that of consumers and the protection of environment, in other words safeties throughout the life-cycle of nanomaterials and products become core issues. Despite the importance of such a safety management, however, it is very difficult to construct the hard regulatory framework for safety, owing to uncertainties and potentialities of nano-risk. In this paper I will look around the ethical principles and guidelines for safety management which are preferentially required before going into the discussion on the construction of hard-regulation such as law and something like that. Under the circumstance that hard-regulations for safety management are not implementable, these principles and guidelines are expected to play a leading part in building the responsible risk-governance framework for nanomaterials and nanoproducts, and finally to become a cornerstone of the hard risk-governance framework.

This study was conducted to raise awareness of careers in the Department of Library and Information Science (LIS) as well as to investigate current awareness and preferences for LIS Department as a strategy to cope with the rapidly changing university environment. To do this, a survey of high school students was carried out, with results as follows: First, awareness about the LIS Department and awareness about librarians in our country's high school students was very low. Second, for possible careers in LIS Department, students responded that a graduate of LIS department was likely to enter the workplace in public libraries, state libraries, university libraries, or school libraries, but they would like to work at broadcasting library, national libraries, school libraries, university libraries, public libraries, or portals. Third, awareness of the career path for the LIS Department showed a very large impact on a preference for the LIS Department. Therefore, students who have heard about the LIS Department are highly probable to select this department when they reach university.

Background: To identify work-family balance and level of happiness among married women dental hygienists in Seoul and Gyeonggi Province. The goal of this study is to use the outcome as basic data to determine the compatibility of dental hygienists with work and family, systems, and improvement of happiness levels. Methods: From July 3 to August 10, 2020, 250 dental hygienists in Seoul and Gyeonggi Province were targeted. The questionnaire comprised 65 questions, including general characteristics (perception of work-family balance, perception of work-family balance system, job satisfaction, parenting type, happiness level) whether or not they were implemented. The results were obtained through a self-control questionnaire. Results: The perception of work-family balance was significantly different in job rank and average income, while that of the work-family balance system had significant differences in workplace type, total work experience, current job work experience, childcare system status, and parental leave period. Happiness level and job satisfaction were significantly different in job rank, average income, and childcare system status. Additionally, the perception of work-family balance and that of the work-family balance system showed a positive correlation with job satisfaction and happiness level. Finally, the perception of married women dental hygienists toward work-family compatibility was determined, where the higher the satisfaction with the job, the higher the level of happiness. Conclusion: To improve the work-family balance and job satisfaction of dental hygienists and their levels of happiness, changes in social perception and improvement of the working environment such as proper staffing, flexible work systems, and incentive systems should be considered.

This study aims to examine whether the relationship between client violence and turnover intentions is mediated by job stress among community mental health social workers. Data of a sample of 1,429 drawn from a study of nation-wide mental health promotion centers in 2013 was analyzed in order to verify both the direct and mediating effects between client violence, turnover intentions, and job stress. The study found that 67.2%(n=961) of the sample experienced client violences in the workplace. Furthermore, the experience of client violences had a direct effect on turnover intentions and job stress had a partially mediating effect on the relationship between client violence and turnover intentions. Based on the results, implications were discussed to reduce the extent of job stress of mental health social workers and to provide a safer work environment.

Background: Workforce health is one of the primary and most challenging issues, particularly in industrialized countries. This article aims at modeling the major factors affecting accidents in the workplace, including general health, work-family conflict, effort-reward imbalance, and internal and external locus of control. Methods: A cross-sectional study was conducted in Esfahan Steel Company in Iran. A total of 450 participants were divided into two groups-control and case-and the questionnaires were distributed among them. Data were collected through a 7-part questionnaire. Finally, the results were analyzed using SPSS 22.0 and Amos software. Results: All the studied variables had a significant relationship with the accident proneness. In the case group, general health with a coefficient of -0.37, worke-family conflict with 0.10, effort-reward imbalance with 0.10, internal locus of control with -0.07, and external locus of control with 0.40 had a direct effect on occupational stress. Occupational stress also had a positive direct effect on accident proneness with a coefficient of 0.47. In addition, fitness indices of control group showed general health (-0.35), worke-family conflict (0.36), effort-reward imbalance (0.13), internal locus of control (-0.15), and external locus of control (0.12) have a direct effect on occupational stress. Besides, occupational stress with a coefficient of 0.09 had a direct effect on accident proneness. Conclusion: It can be concluded that although previous studies and the present study showed the effect of stress on accident and accident proneness, some hidden and external factors such as work-family conflict, effort-reward imbalance, and external locus of control that affect stress should also be considered. It helps industries face less occupational stress and, consequently, less occurrence rates of accidents.

This review aimed to identify risk factors for occupational accidents and illnesses among young workers in the Nordic countries and to attain knowledge on specific vulnerable groups within the young working force that may need special attention. We conducted a systematic review from 1994 to 2014 using five online databases. Of the 12,528 retrieved articles, 54 met the review criteria and were quality assessed, in which data were extracted focusing on identifying occupational safety, health risk factors, and vulnerable groups among the young workers. The review shows that mechanical factors such as heavy lifting, psychosocial factors such as low control over work pace, and organizational factors such as safety climate are all associated with increased injury risk for young Nordic workers. Results show that exposures to chemical substances were associated with skin reactions, e.g., hand eczema. Heavy lifting and awkward postures were risk factors for low back pain, and high job demands were risk factors for mental health outcomes. The review identified young unskilled workers including school drop-out workers as particularly vulnerable groups when it comes to occupational accidents. In addition, apprentices and young skilled workers were found to be vulnerable to work-related illnesses. It is essential to avoid stereotyping young Nordic workers into one group using only age as a factor, as young workers are a heterogeneous group and their vulnerabilities to occupational safety and health risks are contextual. Politicians, researchers, and practitioners should account for this complexity in the education, training and organization of work, and workplace health and safety culture.
