With the need for efficient maintenance technology to reduce maintenance costs for steel bridges, repainting robots are being developed to automate the work in narrow and poor bridge spaces. The repainting robot is equipped with a blasting module to remove paint layers and contaminants. This study developed a prototype monitoring module to be mounted on the repainting robot. The monitoring module analyzes the condition of the painting surface through a camera installed in the front, guides the direction of movement of the robot, and provides the operator with a video to check the working status after blasting through a camera installed in the back. Various image visibility enhancement technologies were applied to the monitoring module to overcome worksite challenges where incomplete lighting and dust occurs.

Objectives: Masked hypertension is associated with metabolic risks and increased risk of cardiovascular disease. The purpose of this study was to identify the frequency of and risk factors of masked hypertension in Korean workers. Methods: The study was conducted among 121 employees at a hotel in Gyeongju, Korea, from December 2008 to February 2009. We measured blood pressure (BP) both in the clinic and using 24-hour ambulatory BP monitors for all subjects. Hypertension was defined independently by both methods, and subjects were classified into four groups: true normotension, masked hypertension, white coat hypertension, and sustained hypertension. Results: The frequency of masked hypertension in our study group was 25.6%. Compared with true normotension, the factors related to masked hypertension were male gender (odds ratio [OR], 10.7; 95% confidence interval [CI], 1.41 to 81.09), aging one year (OR, 0.88; 95% CI, 0.78 to 0.99), clinic BP 120-129 /80-84 mmHg (OR, 8.42; 95% CI, 1.51 to 46.82), clinic BP 130-139 / 85-89 mmHg (OR, 12.14; 95% CI, 1.80 to 81.85), smoking (OR, 5.51; 95% CI, 1.15 to 26.54), and increase of total cholesterol 1 mg / dL (OR, 1.05; 95% CI, 1.02 to 1.08). In males only, these factors were clinic BP 120-129/ 80-84 mmHg (OR, 15.07; 95% CI, 1.55 to 146.19), clinic BP 130-139/ 85-89 mmHg (OR, 17.16; 95% CI, 1.56 to 189.45), smoking (OR, 11.61; 95% CI, 1.52 to 88.62), and increase of total cholesterol 1 mg/dL (OR, 1.05; 95% CI, 1.01 to 1.09). Conclusions: The frequency of masked hypertension was high in our study sample. Detection and management of masked hypertension, a known strong predictor of cardiovascular risk, could improve prognosis for at-risk populations.

The purpose of this study was to investigate the effect of nutrition counseling on improving metabolic syndrome (MS) risk factors. Sixty-eight subjects were grouped according to their numbers of MS risk factors. Subjects who have three or more risk factors of MS were defined as "High risk", subjects who have two risk factors of MS were defined as "low risk", and subjects who have below two risk factors of MS were defined as "no risk" group. All groups finished nutrition counseling every three weeks for 12 weeks. Anthropometric, dietary assessments (24 hr-recall) and blood samples were measured at 0 and 12 weeks nutrition counseling. After 12 weeks of intervention, anthropometric data (weight, BMl, body fat (%), and waist/hip ratio) were significantly decreased (p < 0.05) in all groups. Daily consumption of calorie was decreased significantly (p < 0.05) in the group of low risk and high risk. Blood level of fasting plasma glucose was significantly decreased (p < 0.001) in all groups after 12 weeks of intervention. Significantly, the fasting plasma glucose level was returned to normal range in the high risk group. The number of people who have three or more risk factors of MS (high risk group) was decreased from 25 to 12. Sum of MS Criteria decreased from 85 to 52 in the group of MS and decreased from 143 to 99 in all groups. These results indicate that nutrition counseling for male workers at the worksite proved to be helpful by reducing the risk factors of MS and thereby reducing the risk of cardiovascular disease. Continuing and systematic nutritional management programs should be developed and implemented for male workers at the worksites.

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.

Obesity, a state of having excessive body fat enough to attack one's health, is most blamed for causing chronical degenerative illness such as hypertension, diabetes mellitus as well as arteriosclerosis. According to many studies, the program for the weight control was the most demanded at the worksites. This study was designed to investigate the correlation between the degree of obesity and blood parameters of the employees at the worksites. The results of periodic medical examination for 571 employees(male: 418, female: 153) were analyzed; Age, BMI, systolic blood pressure(SBP), diastolic blood pressure(DBP), hemoglobin(Hb), fasting blood sugar(FBS), total-cholesterol(TC), serum glutamic oxaloacetic transaminase (sGOT), serum glutamic pyruvic transaminase(sGPT) and $gamma$-glutamyl transpeptidase($gamma$-GTP). Pearson correlation coefficient was used to find out the correlation between BMI and each blood parameters. In the case of male, 27.3% of the subjects were over-weight. The subject's age and their blood levels of uric acid, FBS, sGOT and sGPT did not show any significant difference regardless of BMI's, while SBP, DBP, Hb, TC and $gamma$-GTP levels of the overweight group were significantly higher than those of normal group. In the case of female, 9.2% of the subjects were over-weight. This study shows that the implementation of weight control program is required at the worksites

Increasing occupational cerebrovascular & cardiovascular disease, it becomes the most serious problem in the occupational health management. Hypertension is the most important risk factor of cerebrovascular & cardiovascular disease. Although treatment for hypertension has the priority, hypertension has not been managed systematically at the worksite. The objectives of this study were to investigate the actual situation of its treatment, figure out what factors can affect compliance for hypertension treatment and analyze the relations between compliance and employment status. Subjects were 28 workers who have been diagnosed as hypertension at periodic health examination, 20 workers who have been managed for hypertension at dispensary and 22 workers who were diagnosed during the study periods. The results of the study were as follows; 1. More women have been hired as part time workers and had lower education background and income than the full time workers. 2. Among the factors that have been known to affect the treatment compliance, part time workers had less supports from the company than full time workers. 3. We got the comparison of difference between compliance and variables that the factor grade of cure promotion and average ages are high in high compliance. In conclusion there were not the difference of compliance by employment status. But it was hard to rule out the selection vias because the sample size was so small. So it seems difficult to generalized the conclusion that employment status doesn't affect the treatment compliance.

Purpose: The purpose of this study was to examine perceived needs for exercise programs among adults in the workforce based on sociodemographic characteristics and health-related behaviors. Methods: The sample consisted of 182 office workers, sales workers, and service workers recruited at a worksite in Seoul (97 males and 85 females, Mean age=34.6, SD=7.71). Study participants completed a structured questionnaire on health-related behaviors and areas of needs for exercise programs. Analysis of data was performed using descriptive statistics and chi-square tests. Results: Workers with greater interest in exercise reported to engage in exercise. Significant differences were observed in goals of exercise, preferred exercise, preferred methods for delivery of exercise, preferred exercise monitoring, and social support for exercise maintenance according to age, sex, marital status, education, commuting time, occupation, alcohol use, smoking, and current participation in exercise. There were no differences in areas of exercise program needs by consumption of high calorie foods. Conclusion: Public health nurses can use these findings for development and implementation of tailored exercise programs to promote health for workers whose physical activity is insufficient.

Ethnography, a major research method in Anthropology, has been recently applied in human-centered design research. Since ethnography has empirical, naturalistic, holistic and eclectic characteristics, it is needed a guideline to apply ethnography into design research in accordance with a characteristic of project. Design project in which ethnography is applied can be categorized by two criteria; degree of newness of project goal(existing user-potential user) and limitedness of worksite(site-oriented-work-oriented). Among work-site activities, technology in use, and user group culture, it should be decided which content to content to focus more than others and thus what kinds of research techniques to apply in the ethnographic research.Case study was to design an interior of a Korean express train. This project is site-oriented and has an existing-potential users. Therefore, video ethnography was effectively applied to obtain chronological data of activity potential users. Therefore, video ethnography was effectively applied to obtain chronological data of activity flow, and participant observation was applied to obtain statistical data of synchronous activities. Case study shows a concrete process example of how to apply ethnography into design research.
