The purposes of the present study were: (1) to investigate aeromedical dissorders prevalent among ROK air force pilots and (2) to evaluate their detrimental effects on flight performance. The study examined the eight flight-induced disorders primarily responsible for permanent grounding and flying restrictions. According to the survey of 600 randomly selected pilots, 80.2% of the respondents have experienced low back pain, which was 20% higher than the lifetime prevalence in Swedish male workers. Bradyacusia ranked second (56.0%) resulting from continuous exposure to high aircraft noise. The cardiovascular disorders, the most common cause for permanent grounding of Canadian forces pilots, were found in 16.0% of the Korean pilots. Due to the high prevalence of the disorders, in 1993 the Korean pilots received medical treatments 10 times as many as factory workdes. Compared to the flight performance of Israeli and British pilots in wars, the flight performance of the Korean pilots was found to be inferior. Such poor performance can be attributable to the high incidence rates of disorders. Statistical analyses revealed that the aeromedical disorders were related to personal variables such as age, flight career- related factors, and fatigue. Cigarette smoking and drinking habit contributed to worsening back pain, barotitis media, and pulmonary disorders. More comprehensive research was recommended to identify health hazards, combined with intervention to minimize disorders that could lead to early termination of flight careers or excessive loss of flight time. This study further suggests that aeromedical institutions in Korean air force should be fostered more professionally and financially.

The aim of this study was to evaluate the safety and efficacy of treatment of mesoglycan. This study was conducted between September 2003 and May 2004. A total of 292 patients with vascular disorders including cerebral infarction were enrolled. The patients were administered with 50-100mg of mesoglycan by an oral route everyday for eight weeks. Subjective physicians' assessments of efficacy had ratings of 'improvement', 'invariability', 'exacerbation' and 'not being able to assess'. An improvement was observed in 241 patients out of 274; 18 patients were rules out. The efficacy rate was influenced statistically significantly by the duration of therapy (p=0.0392) and daily mean drug dose (p<0.0001). The adverse events were reported in 8 patients (9 cases) out of 292 patients: skin/appendages disorders (0.7%), liver/biliary system disorders (0.7%), cardiovascular system disorders (0.7%), neurologic disorders (0.3%). respiratory disorders (0.3%) and gastrointestinal system disorders (0.3%). There showed no serious adverse events. These results indicate that mesoglycan was well tolerated and effective for the prevention of vascular disorders.

Objectives : The aim of this study was to assess the distribution of general characteristics and risk factors according to onset time in acute stroke patients. Methods : We studied hospitalized patients within 4 wks after the onset of stroke who were admitted to the Department of Internal Medicine at Kyunghee University Oriental Medical Hospital, Kyunghee University East-West Neo Medical Hospital, Kyungwon University Songpa Oriental Medical Hospital, Kyungwon University Incheon Oriental Medical Hospital, and Dongguk University Ilsan Oriental Medical Hospital from April 2007 to August 2008. The 24-hour day was divided into quartiles (6:00 to 12:00, 12:00 to 18:00, 18:00 to 24:00 and 24:00 to 6:00). We analyzed the general characteristics and risk factors according to onset time in acute stroke patients. Results : 468 subjects were included into the final analysis. 1. The most common time period for ischemic stroke onset was between 6:00 and 12:00. It demonstrated a 50% excess risk between 6:00 and 12:00. 2. On the demographic variables of the patients, the rate of hypertension was significantly higher from 18: 00 to 24: 00 than 24:00 to 6:00. 3. There was no significant difference of stroke type, Sasang constitution, or lifestyle between times. 4. According to the blood test, high density lipoprotein cholesterol was significantly higher at 24:00 to 6:00 and lower at 12:00 to 18:00 than other time-groups. 5. The patients diagnosed with metabolic syndrome were significantly more at 12:00 to 18:00 and fewer at 24:00 to 6:00. 6. Hypertension and coffee drinking showed close relationship with patients whose stroke occurred while awake in multivariate analysis. Conclusions : The above results showed that the overall tendency of acute stage cerebral infarction patients varied according to their onset time. These results can be utilized in the future as a basis material.

Objectives : This study aimed to clarify the relationship between the Oriental medical diagnosis and arteriosclerosis by measuring carotid-ankle vascular index(CAVI) in acute cerebral infarction patients. Method : One hundred thirty-one subjects were recruited from the patients admitted to the Internal Medical Department at Kyunghee University Oriental Medical Center from April 2007 to August 2008. We sorted cerebral infarction patients and assessed one hundred fourteen patients' CAVI data. We diagnosed dampness-phlegm by Oriental medical diagnosis and evaluated stroke type by single or multiple infarctions. then, we analyzed their characteristics with type of stroke, risk factor, lifestyle, metabolic syndrome and dampness-phlegm diagnosis. Result : 1. On the demographic variables of the patients, age, hypertension, hyperlipidemia, multiple infarction group and metabolic syndrome and dampness-phlegm group were significantly higher in the high CAVI score group than in the control. 2. According to the significant difference in the dampness-phlegm group, we analyzed dampness-phlegm related index for pattern identifications by CAVI score. As a result, dark circles, insomnia, headache, white coating tongue. slippery pulse, and rough pulse were significantly higher in the high CAVI score group then in the control. 3. In multivariate analysis, age, hypertension, multiple infarction and dampness-phlegm groups showed a close relationship with the high CAVI score group. Conclusions : According to the analysis, significance between dampness-phlegm diagnosed patients group and high CAVI score were clarified. Moreover, multiple location infarctions also have a relationship with high CAVI score in cerebral infarction patients. These results can be utilized in the future as a basis material.

Objectives: This study was to assess characteristics in acute stroke patients according to Sasangconstitution (SC). Methods : We assessed the type of SC of acute stroke patients in $2^{nd}$ Department of Internal Medicine at KyungHee University Oriental Hospital from October 2005 to September 2006. Each subject's SC type was confirmed when the result of QSCC II+ was in accordance with the opinion of the Sasangconstitutional medicine specialist. We investigated general characteristics, stroke type, blood test results, alcohol drinking, smoking and dietary preferences according to SC. Results: 108 subjects were included in the final analysis. This study showed that out of the total patients, the proportion of So-yang to Tae-eum to So-eum was equal to 5.5 to 3.5 to 1. Especially, men were higher proportion So-yang while women recorded a more significant ratio of Tae-eum. Also, the BMI, waist circumference, hip circumference, and WC/HC ratio recorded significantly high results. The result indicated that even though the Tae-eum let on the highest numerical value in the aspect of their past history and the final diagnosis, no significant difference was revealed according to SC. The ratio of cerebral infarction to cerebral hemorrhage was 9 to 1. SVO, LAA, SUE are the 3 types of cerebral infarction classified by TOAST; SVO ranked the highest while SUE ranked the lowest in all constitutions. The blood test result displayed that averages of both TL and the T-chol were the highest in Tae-eum while that of hematocrit in So-yangand that of HDL-chol in So-eum. However, there was no significant difference. There were no significant differences classified by gender or by SC in the aspect of the alcohol drinking and smoking history. The majority of So-yang and Tae-eum demonstrated a preference for meat while So-eum and So-yang displayed high preferences for sea food. Conclusions : With respect to these results. we could observe the general disposition of various characteristic distributions according to SC of acute stroke patients. For further research in this field. it seems necessary to construct fundamental databases for the prevention and treatment of stroke by increasing the number of patients observed and by analyzing delicate characteristics of each constitution type.

The purpose of this study was to evaluate barriers to pharmacists' routine work in community setting. A survey was given to 281 pharmacists who enrolled in 16-week clinical pharmacy educating program in continuous education center for advanced pharmacy at Seoul National University. Three main questions that pharmacists were asked to answer were: (1) difficulties on dispensing prescription, (2) difficulties on communicating with doctors, (3) most difficult disease on patients counseling. The response rates for the survey were more than 60 % for each three questions (62.63 %, 63.7 %, and 64.41 %, respectively). The top three barriers to dispensing prescription were lack of professional knowledge about medications, prescription error and its solving ability and patient counseling. The top three barriers to communicating with doctors were lacking of opportunity to discuss about patients' medication due to unavailability of doctors, doctors' attitude using authoritative manner, and a pharmacist's lack of knowledge. The top 4 most difficult diseases on patients counseling were cardiovascular disorders, dermatologic disorders, endocrinologic disorders, and psychiatric disorders.

Objective: In this review we discuss the health effects among office workers. Background: Even if office workers are not exposed hazardous or harmful environment frequently, some problems could be happened to the office workers. Although serious occupational diseases rarely occur to the office workers, it is important to consider occupational risk factors for the office worker because the portion of the office workers is relatively high in all industries. Method: We divided possible health effects for the office workers into three categories; musculoskeletal disorders, indoor environment, and cerebro-cardiovascular diseases. We reviewed related articles, textbooks, and statistical materials non-systematically and described risk factors, related illnesses, and prevention strategies on each category. Results: Office workers have various musculoskeletal disorders to be intervened. By medical treatment, improving working environment, and ergonomic intervention, office workers can be prevented from musculoskeletal injuries. Poor indoor environment can cause many building-related illnesses or sick building syndrome. Although the etiology of some problems by poor indoor environment is not clear, it helps to maintain adequate humidity, temperature, and clarity of indoor air. Cerebro-cardiovascular diseases are a rising issue because office workers in Korea tend to work for a lot of time. To prevent the diseases, it is needed to work for adequate time, lengthen activity level, and manage other medical risk factors for the diseases. Conclusion: There is no distinct occupational disease for office workers. However, there are some aspects to consider the health effects of office workers and it is important to prevent the possible health problems. Application: A strategy against occupational diseases among office workers can be established by reviewing this article.
