Purpose. This study assessed the actual status of oral health behaviors, oral health consciousness and oral health belief with workers at work sites in some regions and would utilize the results of changes in the hygiene status in the oral cavity as basic materials for developing an education program for the oral health promotion of workers at work sites with the implementation of oral health education and oral health promotion program. Methods. The subjects of the study were 106 workers who expressed their intention to participate in a program in SMEs that agreed on the activities of an oral health education program through an education once per week, of the SMEs with less than 500 persons, located in G. City. General characteristics and the questionnaires of the items on the survey were investigated with a self-administered method, and the collected data were statistically analyzed, using SPSS 20.0. Results. As a result of research, it was noted that PHP-Index, the dental plaque index in the oral cavity became lower from 2.02 points to 1.00 point with continuous management and practice of oral promotion behaviors, and that the oral hygiene status improved. Conclusions. In order to promote the oral health of workers at work sites, substantially, it would be necessary to introduce an oral health promotion program they can practice themselves and through continuous education of oral health by assessing their consciousness and the actual status of their oral health behaviors, and it is expected that their oral health would be promoted ultimately by changing workers' oral health behaviors and consciousness.

Purpose: The purpose of this study was to examine the impact of encounters with customer violence on the mental health of customer service workers, and to verify the moderating effect of coworker support. Methods: Workers who indicated that they engaged directly with individuals other than coworkers for more than 25% of their working hours, such as customers, passengers, students, and patients, were the focus of the 6th Korean Working Conditions Survey in 2020. A total of 13,682 people were chosen as the final research subjects, responses from dishonest respondents who had picked "don't know/no answer" or indicated "reject" to pertinent topics such mental health level, were discarded. After adjusting for socio-demographic and vocational characteristics that influence mental health in customer service workers, a hierarchical regression analysis was executed, which incorporated input on customer violence experiences, coworker support, and interaction terms on a step-by-step basis. Results: It transpired that interactions with customer violence had a negative impact on workers' mental health. Additionally, it was shown that workers' mental health status as coworker support increased. Conclusion: This study's limitations include differences in the period the questions were posed, and limitations in interpretation to all workers. And it is difficult to determine the relationship between the frequency of customer violence, occupational characteristics and mental health. Despite its limitations, this study makes an important contribution toward fostering an environment where coworkers can continue to help one another.

Purpose: We reviewed the cases of occupational diseases that occurred in healthcare workers from 2010 to 2019 and the cases of epidemiological investigations conducted by the Occupational Safety and Health Research Institute for them. Methods: In this study, gender, age, working period, occupational characteristics, and disease characteristics by occupation, which are general characteristics of healthcare workers approved for occupational diseases. In addition, 32 cases of epidemiological investigation of healthcare workers conducted by the Institute for Occupational Safety and Health for the past 10 years (2010~2019) were analyzed. Results: The gender, age, working period, occupational characteristics, and disease characteristics by occupation of medical workers recognized as occupational diseases were all statistically significant (p<.001). In the epidemiological investigation, ionizing radiation( 50.0%) and stress (33.3%) were recognized as disease-related factors, and even in cases of disapproval, ionizing radiation (60.0%) and shift work (25.5%) were designated as related factors. And it was statistically significant (p=.008). Conclusion: The current study identified the types of diseases, various causes, and general characteristics and occupational characteristics that occur frequently in healthcare workers. Therefore, if this study is used as basic information to set the priority and direction of disease prevention project for healthcare workers, it is judged that it will be helpful in preventing industrial accidents.

In order to investigate the prevalence of occupational disease in coal mine workers in Chonnam area, a cross sectional study was conducted in 1,097 workers from September to December in 1987. The results were as follows; 1. The prevalence of pneumoconiosis including suspected cases was 6.9% and was increased by age and working duration. 2. The prevalence of pneumoconiosis excluding suspected cases was 2.8%. 3. By the kind of job, prevalence of pneumoconiosis including suspected cases was l2.9% in tunnel drivers, 6.3% in coalface workers and 6.0% in other workers. 4. The prevalence of noise induced hearing loss was 5.1% and was increased by age and working duration. 5. The prevalence of noise induced hearing loss was the highest among tunnel drivers(7.3%), but it was not significantly different by the kind of job. 6. Occupational disease caused by vibration was not found in coal mine workers.

The conventional database evaluation method is carried out by the way in which the person in charge of each specialty database(DB manager) composes the evaluation sheets for corretionㆍrevision on the already-constructed database in a manual method and carries out the measurement and re-education of DB workers based upon it. As a result, that way consumes much time on career information and measurement works about DB workers, causing low time and cost efficiency and lack of systematic management of DB workers, resulting in becoming the hindrance factor of databases quality improvement. This research provides on-line, red-time results of measurements about the efficiency of DB production and DB workers by combining the static measurement with dynamic measurement by DB manager, both of which utilize the System. Therefore, the DB manager can contribute to the improvement of DB quality by determining the continuation of DB production by DB workers or carrying out the re-education of DB workers without being affected by time or spacial constraints.

This study analyzes the causes of increase in temporary workers observed in the recent Korean labor market. In the analysis of sectors with relatively high ratio of temporary workers, the manufacturing sector tends to hire temporary workers in order to raise profitability, while wholesale & retails and construction sectors tend to employ temporary workers due to the fluctuation of product demand. Another possibility is that with the expansion of college graduates, it is likely that temporary jobs are used as a screening device to reduce the uncertainty of workers quality.

Cloud computing is a new style of computing in which dynamically scalable and reconfigurable resources are provided as a service over the internet. The MapReduce framework is currently the most dominant programming model in cloud computing. It is necessary to protect the integrity of MapReduce data processing services. Malicious workers, who can be divided into collusive workers and non-collusive workers, try to generate bad results in order to attack the cloud computing. So, figuring out how to efficiently detect the malicious workers has been very important, as existing solutions are not effective enough in defeating malicious behavior. In this paper, we propose a security protection framework to detect the malicious workers and ensure computation integrity in the map phase of MapReduce. Our simulation results show that our proposed security protection framework can efficiently detect both collusive and non-collusive workers and guarantee high computation accuracy.

Effective and sustainable prevention of work-related musculoskeletal disorders (WR-MSDs) remains a challenge for preventers and policy makers. Coordination of stakeholders involved in the prevention of WR-MSDs is a key factor that requires greater reflection on common knowledge and shared representation of workers' activities among stakeholders. Information on workers' strategies and operational leeway should be the core of common representations, because it places workers at the center of the "work situation system" considered by the intervention models. Participatory ergonomics permitting debates among stakeholders about workers' activity and strategies to cope with the work constraints in practice could help them to share representations of the "work situation system" and cooperate. Sharing representation therefore represents a useful tool for prevention, and preventers should provide sufficient space and time for dialogue and discussion of workers' activities among stakeholders during the conception, implementation, and management of integrated prevention programs.

In the case of aviation maintenance work, several kinds of shift works are performed during day and night, and a lot of works are performed on the ramp due to the characteristics of the aircraft flight schedule. Maintenance workers are often exposed to the sun or in cold temperatures for aircraft maintenance works. The fatigue risk of the maintenance workers will be weighted. In particular, the work at night shift under normal biological rhythms can make maintenance workers feel sleepy during daytime work. It can also affect the safety of aircraft and individual workers. Accordingly, this study will consider fatigue-related previous researches in the field of aviation maintenance, review the effects of shift work, and how fatigue affects aviation mechanics during the day/night shifts. Considering these factors, we tried to present a plan that can minimize the fatigue of aviation workers through this study.
