There has been a rapid growth in Korea since 1962 because of the success of the 5-year Economic Plan. The number of industrial work and workers has also made had a rapid increase. Consequently, the management of occupational health for the purpose of promoting health in industrial workers is needed especially in the health examination program. The purpose of this study was to analyze the Knowledge, and Attitude among industrial workers of health examination programs. The target population was 402 industrial workers from 4 factories in Kangwon province. A survey was conducted to collect data by a self administered questionnaire from October 29 to November 5. A sixty four item questionnaire was designed to collect data concerning Knowledge, and Attitude of health examination of industrial workers. The data was analyzed by means of percentage, mean, T-test, ANOVA, Pearson's correlation coefficient. The major findings were as follows : 1. The respondents presented the following picture : The male population was 88%. 57% of respondents were age 25-34 years old. 69.4% of respondents were married. 73.4% of respondents were high school graduates. 80.8% of the respondents were working over 48 hours per week. The respondents with over 10 years on the job were 31.9% of the respondents. Health examination were given to the respondents as: pre-employment health examination 90.5%, general health examination 91.5%, and special health examination 31.5%. 2. The Knowledge level was different in health examination items. 80.5% of respondents had knowledge about hearing test, body weight, visually, chest X-ray like simple things. Below 50% of respondents had knowledge of urine test, liver function test, and career history. 3. Attitude status about health examination showed an average score 36.5(median 33) of satisfaction, 26.93(median 21) of importance, 13.84 (median 21) of content, 10.46(median 12 of reliability on health examination results. 4. The level of Attitude on health examination was significantly different than the Knowledge level. 5. The relationship among stated variables such as satisfaction, the perceptions of importance on health, health examination, the result and follow up after health examination were shown to reflect neither positively nor negatively on each other.

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.

This study was carried out to examine information regarding usage of health improving agents and health status of male workers in the Chonnam Yeosu industrial area. We obtained data by means of a questionnaire from 329 men. Of the subjects 44.7% were in their forties, high school education was 43.0%, married was 83.0% and $1,500{\sim}3,000$ thousand won in monthly income was 35.8%. Average height and weight of the subjects was $171.8{\pm}5.4 cm$ and $70.5{\pm}8.1 kg$. Average BMI was $23.8{\pm}2.2$. Drinking rate of respondents was 85.5%, the drinking rate of daily workers was significantly higher than rotation workers (p < 0.05). Rotation workers exercised more regularly than daily workers (p < 0.001). Subjective symptoms of the subjects always had eye problems (11.7%), shoulder aches (5.8%), ache in one's empty stomach (4.7%) in decreasing order. 21.4% of the subjects had a disease, and liver disease was the highest in the subjects; the second was cardio-vascular disease. Interval of health food intake was highly irregular (62.7% of respondents), and keeping healthy was the main motivation fur the usage of health foods. Health improving agents included oriental medicine, animal protein based restorative foods, nutrition supplements, health supplements, and natural foods. 33.3% of the subjects took health supplements, nutrition supplements (29.1%), oriental medicine (20.6%), natural foods (16.7%) and animal protein based restorative foods (3.9%), in respective order. Health improving agents were consumed higher in liver disease than other diseases. This study suggests that nutritional education and monitoring should be implemented for industrial workers to prevent life-habit diseases and to keep proper self-management of health status under special environments.

A cross-sectional study was performed to estimate the nutritional status of Korean male lead workers and to assess the relationship between calcium nutritional status and blood lead levels. A flood consumption survey was conducted by the 24-hr recall method with 118 lead workers and 63 non-lead exposed controls. Blood lead levels were analyzed from whole blood and serum calcium concentrations were also assessed. Results of dietary analysis showed Korean lead workers consumed relatively sufficient nutrients (more than 75% of RDA) except, calcium. Mean dietary calcium intake of lead workers was 502.2mg(72% of RDA) while that of the non-lead workers was estimated as 600.8mg(86% of RDA). Intakes of protein, iron, niacin and vitamin C of lead workers were significantly lower than those of non-lead workers. There was a wide range of blood lead levels(5.5 to 73.5$\mu\textrm{g}$/㎗) observed while mean blood lead level of lead workers was 30.9$\mu\textrm{g}$/㎗. However, 98% of lead workers showed normal serum ca1cium concentrations (range ; 8.9 to 10.7mg/㎗, mean ; 9.77mg/㎗) while 66% of lead workers were estimated to intake a dietary calcium lower than 75% of RDA. Mean blood lead levels of non-1ead workers were significantly lower(mean ; 5.1$\mu\textrm{g}$/㎗, p ＜ 0.001) and the serum calcium concentration was significantly higher(mean ; 10.20mg/㎗, p ＜ 0.001) than lead workers. Results of unadjusted correlation showed that serum calcium level and dietary calcium intake were negatively correlated with blood lead concentration. In a multiple regression of blood lead levels with variables known as affecting blood lead 1eve1 such as age, body mass index and occupational lead exposure, serum calcium was insignificant while dietary calcium intake showed statistically significant(p ＜ 0.05) relation. Since calcium is a very important nutrient to reduce hazardous effects of lead, it should be strongly recommended that lead workers need to increase dietary calcium intake.

Today, we can see the more serious industrial accidents than in the past according to the high growth rate of industrial society. Therefore, from the corporate as well as the human viewpoint it pays to have workers adequately trained and safety - oriented. The cost of accidents is high in terms of medical insurance costs lost time on the job, legal fees for court cases, workers' compensation, disability insurance, and unemployment compensation. The cost of preventing occupational accidents or illnesses is much less then the cost of treatment or workers' compensation. In this study, we investigate the situations of industrial accidents and safety control of 277 coporates in Busan, analyze the causes of accidents and propose the countermeasures to each of causes.

Background: This study investigated the status of oral health promotion activities for adult workers in public health centers and industrial dental offices and provided basic data for the model development of oral health promotion program for adult workers in Korea. Methods: A questionnaire was developed separately according to the person who in charge of the oral health promotion activities in public health centers nationwide and dental hygienists working in 20 industrial dental offices. This survey was conducted through postal survey and consisted of 29 items and 35 items respectively, including 19 common items for general information, oral health promotion program status and opinion. Statistical analysis was performed using the IBM SPSS ver. 23.0. Results: We analyzed the data of 147 public health centers (57.9%) and 9 industrial dental offices (45.0%). A workforce with a lack of practice was the biggest barrier to oral health promotion activities for adult workers. However, both groups showed high intention for the practice of adult worker's oral health promotion activities. Also, they showed willingness to work together in an organic partnership to perform their roles (94.4% and 77.8%, respectively). Regarding the scope of cooperation in the implementation of the industrial oral health promotion activity linked to the public health center, dental hygienists of industrial dental offices responded that they could coordinate necessary matters and schedule management. Conclusion: The development of an oral health promotion program aided by the relationship between public health centers and industrial dental offices is essential for the oral health promotion of adult workers. The possibility of cooperation between the abovementioned centers was confirmed through this study. In a long-term perspective, it would be necessary to identify a method to institutionalize industrial dental hygienists for the provision of continuous oral health care in workplaces.

Background: This study aims to derive the characteristics of each work type for industrial radiography based on empirical evidence through expert advice and a survey of radiation workers of various types of industrial radiography. Materials and Methods: According to a Korean report, work types of industrial radiography are classified into indoor tests, underground pipe tests, tests in a shielded room (radiographic testing [RT] room test), outdoor field tests, and outdoor large structure tests. For each work type, exposure geometry and radiation sources were mainly identified through the expert advice and workers' survey as reliable empirical evidence. Results and Discussion: The expert advice and survey results were consistent as the proportion of the work types were high in the order of RT room test, outdoor large structure test, underground pipe test, outdoor field test, and indoor test. The outdoor large structure test is the highest exposure risk work type in the industrial radiography. In most types of industrial radiography, radiation workers generally used ¹⁹²Ir as the main source. In the results of the survey, the portion of sources was high in the order of ¹⁹²Ir, X-ray generator, ⁶⁰Co, and ⁷⁵Se. As the exposure geometry, the antero-posterior geometry is dominant, and the rotational and isotropic geometry should be also considered with the work type. Conclusion: In this study, through expert advice and a survey, the external exposure characteristics for each work type of industrial radiography workers were derived. This information will be used in the reconstruction of organ dose for health effects assessment of Korean radiation workers.
