Let us study about the ophthalmology in the developing area of the environment of the aerospace. After the launch of Naroho (KSLV-I), Korean people are interested in the development of the technology and environment of the aerospace. It is important to the people who are engaged in the fields of the aerospace that the vision is affected by the environment of the aerospace so much. It can be hypoxia due to high altitude, blurred vision and lowering of the color sense due to mydriasis, disturbance of the light sense due to acceleration and vibration. But thanks to the development of refractive surgery, people can be an applicant for a pilot just 1 year after the surgery. The environment of the aerospace is also special to the area of the ophthalmology. There must be further study about the environment of the aerospace.

The Present State of Health Management and Related Factors in Small Enterprises.
Korean Journal of Aerospace and Environmental Medicine.2004;14(4):158-164.
BACKGROUND: The aims of the study are to investigate the present state of occupational health management (OHM) in small enterprises, to explore the related factors, and to provide the information for effective policy of OHM in those enterprises. METHODS: The study subjects were 155 small enterprises that had referred the measurement of workplace hazards to a hospital at the East Seoul, Korea. Self-administered questionnaire survey was conducted by Fax. The contents of the survey were present state of OHM and related factors. RESULTS: 1. The characteristics of OHM in charge were as follows; among the health manager (1) 81.9% had the high authority, (2) 63.2% could explain workplace hazard, (3) 52.9% had outside professional education, (4) 49.7% recognized the need for occupational health, and (5) 67.7% had pragmatic perspective on workers' health protection. 2. The occupational health activities that showed higher performance rate were as follows; periodic health examination (86.5%), measurement of workplace hazard (92.9%). The occupational health activities that showed lower performance rate were as follows; appointment of emergency hospital (26.5%), replacement health examination (18.1%), health education (30.0%), health promotion (23.3%), preparation of health statistics (14.8%), planning health management (9.7%) 3. As results of multiple logistic regression analysis, the factors associated with the higher activity of occupational health were longer duration(more than 5 years) of health manager in charge(OR=2.41), pragmatic perspective on workers' health protection (OR=3.79), experience of outside professional education (OR=2.40), repair of automobiles(OR=3.31), workplace that employed more than 10 workers (OR=4.02), history of workers' compensation (OR=8.05), employers' high concern (OR=4.61). CONCLUSION: These results suggest that interest of employers and appointment of suitable health manager in charge were important, and minimum regulations and the development of occupational health program integrated with promoting productivity are required to activate occupational health in small enterprise

Role of the Occupational Characteristics in the Effect on a Workplace Smoking Cessation Program.
Korean Journal of Aerospace and Environmental Medicine.2004;14(4):151-157.
BACKGROUND: The aims of the study are to evaluate the effectiveness of a workplace smoking cessation program, and to investigate the role of the occupational characteristics for planning better smoking cessation program (SCP). METHOD: 258 workers' smoking statuses were surveyed. A follow up survey was conducted after 6 Month SCP including campaign, health education, provision of nicotine patches, and smoking cessation incentives. Theup rate was 89.2%. RESULTS: 1. Thesmoking rate was reduced from 67.4% (before SCP) to 45.3 %. The rates after SCP were different by the type of job and the status of employment. The participation rate of the office workers was 32.8%, and that of the technician was 55.6% (p<0.01). The rate of the regular workers was 59.4%, and that of the irregular workers was 36.8% (p<0.05). 2. Among of 174 smokers, 55.9% participated in SCP. According to the type of job and the job position, the participation rate was different. The rate of office workers was 69.9%, and that of the technician was 47.5% (p<0.01). Among the managerial personnel 86.4% participated in SCP, and amongthe plain workers, 52.5% (p<0.01). 3. In multivariate analysis, the smoking cessation rate was higher in office workers (OR=3.21), the group of lower job demand (OR=3.12), that of absence of family stress (OR=2.91), and that of lower perceived stress (OR=3.51). CONCLUSION: The SCP based on social-cognitive theory reduced smoking rate, but increased the difference of the smoking rates by the type of the job. These results suggest that the SCP using social-context model is important to establish the better strategy to stop the smokin

Gender Difference in Work-related Musculoskeletal Disease.
Korean Journal of Aerospace and Environmental Medicine.2004;14(4):142-150.
BACKGROUND: We studied gender difference in prevalence, risk factors, medical management, workplace activities for the prevention of work-related musculoskeletal diseases (WMSDs), and the role of gender in analysis of the factors affecting the prevalence of WMSDs. METHODS: In 3, 339 workers at 29 workplace, questionaire survey was conducted. The questionaire was consisted of personal factors, perceived workload and ergonomic factors (modified KOSHA code H-30), perceived job stress (modified Karasek model). musculoskeletal symptoms, medical management, workplace activities for the prevention of WMSDs. RESULTS: Female workers' overall prevalence of WMSDs (37.4%) was higher than that of male workers (18.9%), and there are many differences in the prevalence by the involved site of the body. The rate of personal risk factors, perceived workload, ergonomic risk factors, and the perceived job stress were higher in female workers than those of male workers. In gender-sensitive multivariate analysis, female worker's prevalence of WMSDs was higher in regular workers (OR=2.08), manufacturing, professional, service workers (OR, 2.25, 3.89, 3.26, respectively)). It was also associated with higher perceived workload (OR, 1.48~1.74), higher ergonomic risk (OR, 1.86~3.65), high job demand (OR=1.62), and low social support by co-workers (OR=1.29). The prevalence of WMSDs of male workers was higher in people living with dependent (OR=1.39), manufacturing workers (OR=1.54), but lower in service workers (OR=0.54). It was also associated with high workload (OR=1.98), higher ergonomic risk (OR, 3.26~5.55), and lower job control (OR=1.39). CONCLUSION: These results showed that female workers' high prevalence of WMSDs is the reflection of 'gendered' workplace, i.e. all aspects of WMSDs have profound association with gender from risk factors to medical management. Therefore, gender-sensitive analysis can reveal more realistic factors affecting WMSDs, and provide more valuable implications in prevention of WMSDs.

Effect of Antioxidant Vitamin Supplementation on Hyperbaric Oxygen Injury in Rats.
Korean Journal of Aerospace and Environmental Medicine.2004;14(4):135-141.
BACKGROUND: Antioxidants vitamin C and vitamin E may protect against the toxic effect of oxygen free radicals that are preferentially produced after exposures to hyperbaric oxygen (HBO). This study investigated the effect of vitamin C and vitamin E on serum nitric oxide (NO) concentration and intercellular adhesion molecule-1 (ICAM-1) expression on lung after HBO exposure. METHODS: Male Sprague-Dawley rats weighing 200 to 250 g were exposed to HBO at 3 ATA of 100% O2 for 3 hours. The experimental groups were given vitamin C (125 mg/day per rat) and/or vitamin E (50 mg/day per rat) orally, from 5 days prior to the HBO exposure to the day of sacrifice. Serum NO concentrations were determined by measuring NO end product nitrite by non-enzymatic Griess assay. Expression of ICAM-1 on lung was observed by immunohistochemical analysis. RESULTS: The serum nitrite levels were significantly increased after HBO exposure and were higher at 24 hours after HBO exposure than at 0 h (P<0.05). The expression of ICAM-1 was weak immediately after HBO exposure and enhanced at 24 hours. There were no pronounced suppressive effects of vitamins on serum NO production and ICAM-1 expression induced by the 3 hours HBO exposure. CONCLUSION: The 3 hours HBO exposure induces the serum NO production and ICAM-1 expression on lung. The short-term supplementation of vitamin C or/and E do not suppress the NO production and ICAM-1 expression on lung.

Health States of Residents near by US Military Camps.
Korean Journal of Aerospace and Environmental Medicine.2004;14(4):126-134.
This study was conducted to evaluate the relation between health states of residents near by US military camps and noise caused by their aircrafts, in the cities of Chuncheon, Gunsan, and Daegue. From November 2001 to July 2002, we surveyed 426 residents for psychosocial well-being states, psychiatric problems, infertility and sleep disorders by questionnaire, and applied pure-tone audiometry to 83 residents for measuring hearing abilities at qualified medical institutes. The residents near by military camps were more suffered from psychosocial and psychiatric problems, infertility, and sleep disorders than residents of the control areas. In the aspects of psychiatric problems, residents living within 50m from the military camp boundaries had 5.42 times higher risk and those living at the outward had 3.57 times higher than the control residents. And nearby residents had more decreased hearing abilities than the control residents by over 10dB in whole frequencies, statistically confirmed by mixed model with age adjustment. The residents near by US military camps were suffered from psychosocial and psychiatric problems, infertility, sleep disorders and hearing disturbances, induced by noise of US military aircrafts.

Coronary Heart Disease in Air Travelers.
Korean Journal of Aerospace and Environmental Medicine.2004;14(4):123-125.
The air medical transport of coronary patients is a rapidly expanding practice. From time to time, the physician is called on to assess risk or advise coronary patients. Commericial aircraft flight presents a highly variable altitude exposure that may result in significant hypoxia for patients with coronary heart disease. When considering elective long-distance air travel of coronary patients, it is necessary to weigh the benefits against the potential risks of flight. Strong contraindications to air travel by coronary patients would appear to be new-onset angina and unstable angina. And myocardial infarction within several weeks or months constitutes a relative contraindication, with persistent angina, ventricular ectopy, and poor ventricular function. These patients and those coronary patients with obstructive lung disease maybe candidates for in-flight oxygen treatment.
