Objectives: This study was conducted to identify the characterization of organics solvent exposure among painting workers in the shipbuilding painting process, especially for their daily variations(within worker variance). Methods: Charcoal passive dosimeters were worn throughout each work shift for 20 days for five painting workers from October 19 to November 26, 2015. A total of 100 samples were collected, analyzed and compared with statutory workplace environmental measurements. Results: The geometric mean(GM) and geometric standard deviation(GSD) of mixed organic solvent(six substances) exposure index(EI) for the 100 samples were 0.42 and 4.42 respectively. The median and range of GSD for within worker EI representing five workers' daily EI variation is 3.72 and 2.63 ~ 5.20, respectively, which is classified as a very large variation(GSD>3). We were able to divide the painting process into two similar exposure groups(SEGs), Touch-up and Spray. Spray painting workers were much more exposed to organic solvent than Touch-up painting workers(GM=0.71 vs. 0.19), but less variably (GSD=3.64 vs. 4.10). xylene is the substance to which the workers were most exposed(GM=16.19 ppm, GSD=4.36), and the exposure characteristics of six substances including xylene is similar to those of EI. Conclusions: The daily variation of organic solvent exposure in the shipbuilding painting process is so high that statutory Assessment of Reliability of Work Environment Monitoring needs to be conducted with statistically sufficient number of samples and evidence.

This study identified the health habits affecting health status of industrial workers. Data was collected from 965 workers in 58 companies at Buchon. The research conducted a self-administered questionnaire survey and obtained the workers' health examination records. The results were as follows: 1. Among 965 respondents, men were 82.4%, women were 17.6%, 44.5% were of the 30${\sim}$40 age group, the married were 67.4%, the single were 30.8%, high school graduates were 81.1% and 38.8% were of people who worked between 1 and 5 years 2. As far as the seven health habits, current smokers were 52.8%, people who regularly exercise was 28.5%, 7${\sim}$8 hour of sleep, on the average were 71.4%, people eating breakfast nearly every day were 8.8%, and people eating between meals almost every day were 46.5%. Heavy drinkers who drink 3${\sim}$4 times or more per week were 14.2%, 1${\sim}$2 times per week were 32.6% and the obese were 9.3%. 3, Health status of A and B, estimated by doctors in the health examination were 80.8% and C, D1, D2, the unhealthy were 19.2%. For men, those who reported more than women in unhealthy groups and the results regarding health status reflects those for gender, educational level and age. That is to say that, lower educational level group and over 30 years of age group perceive their health to be worse than the higher educational level and under 30 age group. And these differences were statistically significant. 4. The relationship between health habits and health status were examined based on the odds ratio. Current smokers had a consistently worse health status than a non smokers with a 1.98 odds ratio. The workers who reported eating breakfast rarely or never were more associated with the unhealthy group than the regular breakfast eating group with a 2.96 odds ratio. One or more drink per week had a worse health status than a never or a little drinker with a 1.56 odds ratio. 5. General health habit score and duration of work were selected as significant factors influencing health status from the result of logistic regression analysis. According to the results of this model, the odds ratio of good health status was 2.08 for good health habit score, 1.63 for workers who worked five years or more duration at work. In summary, good health habits were associated with good health status. In particular, the workers who had 5 or more desirable health habits had a significantly better health status than the workers who had 4 or less than 4 good health habits. Therefore, in order to provide the health promotion programs to workers it is necessary to organize clear health management plans based on effective health education and health service perspective. If further research examines health habits and health status using a prospective study design, More precise findings for health promotion program development in the worksite and worksite health management planning.

In all enterprises of Korea employing workers more than five, employeers have a duty of conducting a periodic health screening for improvement and maintaining healthful living and working conditions of employees. The health screening is performed annually in line workers and biennially in table workers under the supervision of the government. But there are some argument to the health screening programme in view of effectiveness, efficiency, reliability and etc. In order to obtain basic reference materials for increasing the efficiency of peridoic health screening programme for workers and understand the attitude of health screening institutions and enterprises toward the periodic health screening, mail questionnaire survey was conducted in July 1987. The questionnaire sent to 950 health screening institutions. and 700 enterprises in whole land but they were returned from 254 health istitutions and 187 enterprises, which were analyzed. The results were as follows: 1) The attitude of the respondents toward the necessity and benefit of the periodic health screening was showed highly positive responses in both of screening institutions and enterprises, and it was more positive in screening institutions. The attitude toward the affirmative and the contentment was showed less positive than that of the necessity and benefit. 2) The respondent recognized may problems on regard to the screening programme. The health screening institutions lie in the state of competition with other institutions for undertaking the screening programme. 3) One of major complaints from enterprises was the lack of sincerity in performing the screening programme. They wanted more practical and reliable health screening examination rather than showy one. 4) Health screening institutions and enterprises showed some mutual contradictions in the matter of screening fee, and so the screening fee should be adjusted to the appropriate cost.

For basic data to develop health management program of female workers. this study was intended to characterize factors affecting health problems of women at workplace which has less than 50 workers by Cornell Medical Index(CMI). 195 items of CMI questionnaire were simplified to 57 items which were composed of 35 items concerning physical health problems and 22 items concerning mental health problems. The data was collected during 6 months from July 10 to December 30 and analyzed with frequency, percentage, t-test and ANOVA. The 107 female workers included in this study was characterized to be mainly twenties(64.5%), single(69.2%) and working at production position(89.7%). The most frequent physical problem was fatigability and the next, neurological system and cardiovascular system. Main mental complaints were inadquacy. anger and tension. When the health problems were reviewed according to its general characteristics, anger in young age, adaptiveness in single and respiratory complaints in self-recognized unhealthy group were prevalent. According to life styles. the prevalent complaints were musculoskeletal one in alcoholic group and cardiovascular one in group who are sleeping just for four to five hours. The appropriateness of each items of CMI should be evaluated to reveal the reasons why meaningful results could not come from many items of this questionnaire. The repeated study should be carried out to figure out the health problems and its related factors of female workers at small scale workplace. Also, exercise program and abstinence from drinking and smoking should be carried out for female worker's health.

The possibility of eye exposure for workers participating in manufacturing of nanoparticles or consumers using products containing nanoparticles has been reported, but toxicity studies on the eye are scarce. In this study, cytotoxicity of five nanoparticles including silver, ceria, silica, titanium and zinc were tested using Statens Seruminstitut Rabbit Cornea (SIRC) cells. When cells were treated with nanoparticles with concentrations of $1-100{\mu}g/mL$ for 24 hr, zinc oxide nanoparticles showed higher toxicity to cornea cells. $LC_{50}$ of zinc oxide nanoparticles was less than $25{\mu}g/mL$ but those of other nanoparticles could not be calculated in this test, which means more than $100{\mu}g/mL$. Generation of reactive oxygen species was observed, and expression of apoptosis related biomarkers including Bax and Bcl-2 were changed after treatment of zinc oxide nanoparticles, while no other significant toxicity-related changes were observed in cornea cells treated with Ag, $CeO_2$, $SiO_2$ and $TiO_2$ nanoparticles.
