This study investigated the current industrial hygiene status of China, a socialistic country, to explore the future direction of industrial hygiene of in Korea. In China, the industrial hygiene is called as labor hygiene, which includes industrial health and industrial hygiene. The main goal of labor hygiene is to protect the health of laborers, promote the productivity and ensure the development of industry and agriculture. Started since the foundation of People's Republic of China in 1949, the labor hygiene developed with the occupational disease science which belongs to clinical medicine, has grown today as an independent science. The labor hygiene has made a rapid progress, especially for the last 20 years. The scope of industrial hygiene was expanded from the prevention and treatment of silicosis to pneumoconiosis and o.ther occupational poisoning caused toxic substances. In addition, not only the prevention of industrial toxication but also the prevention of hazards of phisical causes were included in the scope of industrial hygiene. Based on activation of health centers, the organization for the prevention & treatment of occupational diseases was established at the city, county and state. The industrial hygiene monitoring is being carried out through clear division and partition system.

Objective: The objective of this paper is to examine the scope of ergonomics in relation to the discipline of industrial hygiene. Background: There has been increasing recognition of the importance of ergonomics in the practice of industrial hygiene. As a result, quite a number of ergonomics-related research articles have been published in major industrial hygiene journals. And the professional engineers in industrial hygiene have conducted ergonomics-related activities. Method: This paper reports the results from the literature review of the ergonomics papers published in major industrial hygiene journals for the last 5 years, and the certification of industrial hygiene and ergonomics. Results: It was found that 7.7~13% of the total published papers were about ergonomics, and the number of the professional engineers in industrial hygiene is almost double of that of ergonomics. Conclusion: It should be understood that the work of ergonomic is complementary to industrial hygiene and not in competition with it. Application: Some suggestions were proposed hopefully helpful to colleague ergonomists for future research.

Objectives: The aim of this study is to analyze main problems on occupational safety and hygiene in construction sites and to suggest some improvement methods. In order to decrease industrial accidents, I emphasize the approach paradigm shifts according to characteristics of construction workers. Methods: Pointing out the irrationality of current institutions by comparing bad outcomes of occupational safety and hygiene in construction industry and characteristics of construction workers. Results: In order to decrease industrial accidents, we need some approach paradigm shifts; the supply method of industrial safety and health fundamentals on the construction industry level, the accident rate calculation by using the actual construction workforce instead of an estimation, institutionalizing the prevention efforts themselves for industrial accidents, securing enough production costs for the precondition of occupational safety and hygiene in construction sites. Conclusions: I ascertain the need of the approach paradigm shifts for decreasing industrial accidents in the construction industry.

Objectives: This study investigated the perception and educational needs of the health care professionals in wake of the fourth industrial revolution. Methods: This study was conducted among 115 students from the Department of Dental Hygiene and 122 dental hygienists from Gwangju and Jeonnam, from June 25 to September 20, 2020. The questionnaire consisted of one question on the perception of the concept of the fourth industrial revolution and two questions on the influence of the fourth industrial revolution. It contained a total of eight questions on the desired education hours and education expenditure. Results: The degree of perception of the concept and influence of the fourth industrial revolution was 3.20 for both dental hygiene students and dental hygienists; the average of the two groups was the same. Regarding the educational experience, 'no experience' was the most marked response among both dental hygiene students and dental hygienists and no statistically significant difference was observed (p>0.05). Conclusions: As demanded by the changing times, it is necessary to identify the differences in educational demands of the two groups, develop educational programs according to the fourth industrial revolution, as demanded by the changing times, and apply educational programs that fit the educational needs of each group.

The airborne concentrations of the welding fumes produced during $CO_2$ arcwelding process at shipbuilding, shiprepairing, container manufacturing and car accessary manufacturing industry were investigated. The effects how much reduced the welding fume were checked when the portable fan was used. The results were as follows; 1.The geometric mean of welding fume concentration in shipbuilding factory was $10.05mg/m^3$. This exposure concentration was higher than other 3 manufacturing industries at 95% confidence level. 2. The sampling filters for welding fume could be digested with acid within 1 hour by microwave oven. The recoveries for investigated metal elements were all over 95%. 3. The optimal wavelength could be selected for the simultaneous analysis of 8 metal elements by ICP(Inductively Coupled Plasma). 4. Noxious gases($O_1,NO_2$) produced during $CO_1$ gas arc welding process were detected that the concentration of ozone($O_1$) was less than 0.01 ppm and that of nitrogen dioxide($NO_2$) was 0.01-0.03 ppm. 5. The geometric mean of welding fume particle diameter was $1.26{\mu}m$ and geometric standard deviation was 1.51 for the counts when particle an analyzer(ELZONE) had been used. 6. When the portable fan had been used,the reduced percent of total welding fume for workers was about 47.8% when portable fan was applied to blow and 71.7% when to exhaust.

This study was performed to evaluate the asbestos exposure levels and variations in textile, brake lining manufacturing and slate manufacturing industries. For this study, fifteen plants of brake lining manufacturing industry, 7 plants of textile industry, and 2 plants of slate manufacturing industry were selected and surveyed. Geometric means (GMs) of airborne asbestos concentrations in textile, brake lining manufacturing, and slate manufacturing industries were 1.42 f/cc(0.07-6.1O f/cc), 0.19 f/cc(<0.01-2.67 f/cc) and 0.08 f/cc(0.02-0.67 f/cc), respectively. In textile industry overall GMs of airborne asbestos concentrations in plants with less than 50 workers and in plants with more than 50 workers were 1.60 f/cc and 0.3 f/cc, respectively. Therefore, the size of plant showed some difference in the airborne asbestos concentrations. Three out of 7(42.9%) exceed the Korean standard, 2 f/cc, and every plant exceed the USA standard, 0.2 f/cc of the OSHA-Permissible Exposure Level(OSHA-PEL). Especially, one plant showed the highest average concentration of 2.87 f/cc. In brake lining manufacturing industry, the plants with less than 50 workers showed 0.22 f/cc. The plants with more than 50 workers showed 0.18 f/cc. All plants showed the exposure level below the Korean standard. Five of 15 (33.3%) were above the OSHA-PEL. One plant showed the highest average concentraton of 0.84 f/cc. In slate manufacturing industry, the average exposure level was 0.08 f/cc, and all of the plants were below the Korean standard and the OSHA-PEL.
