OBJECTIVES: To investigate the relationship of serum uric acid to cardiovascular risk factors in Korean male workers. METHODS: We screened 522 male workers at an electrical manufacturing company by a periodic health examination and a questionnaire survey in 2000. We collected data relating to age, smoking status, alcohol drinking status, body mass index (BMI), blood pressure, serum lipid, fasting blood glucose and serum uric acid. The data were analyzed using a variety of methods, including ANOVA, Pearson's correlation, and multivariate regression analyses, to examine the association between uric acid and cardiovascular risk factors with a cross-sectional study design. RESULTS: The concentration of serum uric acid showed positive associations with BMI, total cholesterol, triglyceride, and LDL-cholesterol; it was also significantly correlated to systolic and diastolic blood pressures. Life-style characteristics, such as smoking and alcohol drinking showed no significant association. From the multivariate regression analyses, BMI, total cholesterol and fasting blood glucose levels were found to be independent positive predictors of uric acid; while age, blood pressure and smoking status give no independent contribution explaining the variability of serum uric acid levels. Conclusions : This study demonstrates that serum uric acid level have a significant association with cardiovascular risk factors, such as BMI, total cholesterol and blood glucose in some Korean male workers.

This study conducted to evaluate the association of work posture with cervical spine abnormality toward 106 microwave-oven assemblers. A self-administered questionnaire was used to obtain a general characteristics and a work history of workers. The posture of neck and shoulder joint of workers were measured with video tape recording and the simple X-ray of cervical spine was checked-up to observe the X-ray abnormality including degenerative change, curvature abnormality, disc space narrowing or disc canal narrowing. The result were as follows. 1. The prevalence of degenerative change among cervicobrachial disorder workers was 44.3%(47 persons), curvature abnormality was 43.4%(46 persons), disc space narrowing was 21.7%(23 persons), and disc canal narrowing was 21.7%(23 persons). 2. The prevalence of degenerative change at cervical spine was increased with the degree of neck flexion(flexed versus neutral; odds ratio (OR)=2.7), the total work posture of neck(mild or severe awkward versus neutral; OR=1.2, 3.4). 3. The prevalence of degenerative change at cervical spine was increased with the degree of the right shoulder flexion, the heaviness of the materials carried by the right hand and the degree of awkwardness at the total work posture of right shoulder(p<0.05). 4. There was no evidence of association between curvature abnormality, disc space narrowing, disc canal narrowing and work posture. In conclusion the awkward work posture was related with degenerative change of cervical spine among microwave oven assembling workers and the further study in these field must be made to prove the association objectively.

BACKGROUND: Korea Academy of Family Medicine recommands HBsAb and HBsAb test in youth health promotion program. Adequate management are necessary for prevention of vertical transmission at perinatal period, especially girls' high school students as a future's conceivable woman. Health examination program for the first grade students of high school which was established by the Educational Ministry has been acted since 1998. So, through the students health examination we'd like to find an adequate method of prevention and management in hepatitis B. METHODS: Our study examines HBs Ag/Ab about girls' high school students at two high schools in a city. According to the results of hepatitis B, active intervention in carrier group, passive intervention in candidate were done. And then a year later, hepatitis B management was investigated through the questionnaire. RESULTS: In active intervention group, regular check up of hepatitis B is 21.4%, hepatitis B blood test in family is 39.3% and in passive intervention group, hepatitis B vaccination rate after health examiantion is 9.1%. CONCLUSION: More active intervention such as mass vaccination are required in health examination for the purpose of hepatitis B management at youth.

BACKGROUND: Recently, the apartment complex is rapidly increasing as a new type of housing in a large city. So the purpose of the this survey is to research the experience rate of young children's allergic disease in an area of the apartment complex of a large city and to help the family medical doctor to diagnose and treat the young patients. METHODS: The experience rate of atopic dermatitis, bronchial asthma, allergic rhinitis, allergic conjunctivitis, food allergy was surveyed on June 1999 at an elementary school in a large apartment complex in Kwang ju. The survey group were 832 students attending elementary school from the second to sixth grade. Also this survey was used to elicit information about the relationship between allergic disease and factors such as age, sex, birth history, family history, and home environment. For analysis of our finding, we have been used chi square test. RESULTS: The survey shows that the experience rate of allergic disease is 40.4%. The experience rate of allergic disease was not related with sex, but the more ages the less experience rate. Allergic disease was not related with birth weight, gestational age, feeding method, use of carpet, breeding of pet, smoker in home, and the previous housing type. But experience rate of allergic disease was increased with positive family history. CONCLUSION: General facts of allergic disease in elementary school children had no differentiation between large city and the other region. The experience rate of allergic disease is 40.4%.

This study was performed to find the prevalence and the associated risk factors with low back pain(LBP) of the staffs in a university at Kwang-ju city. The data were collected by a questionnaire including SDS(Self-rating depression Scale) battery from September 1st to October 15th, 1996. The results were as follows; 1. The prevalence rate of LBP during lifetime was 73.1%, 53.1% for the last one year, and 23.6% for the last one week. 2. Statistically significant factors related to LBP during lifetime were sex and satisfaction with job. Sex, smoking, alcohol drinking, occupation, work posture, forward bending of trunk and satisfaction with job were selected as significant factors related to LBP during the last one year. The significant determinants related with LBP during the last one week were sex, smoking, alcohol drinking, occupation, forward bending of trunk and satisfaction with job. 3. Through the analysis of self-rating depression scores according to LBP during lifetime were selected to be female(OR=2.63, 95% CI: 1.08~6.40), dissatisfaction with job(OR=2.16, 95% CI: 1.16~4.15), those for the last one year were chosen to be female(OR=2.30, 95% CI: 1.03~5.12), forward bending of trunk(OR=2.18, 95% CI: 1.26~3.79), dissatisfaction with job(OR=1.84, 95% CI: 1.06~3.21), and those for the last one week were female(OR=3.00, 95% CI: 1.17~7.69), forward bending of trunk(OR=2.85, 95% CI: 1.38~5.88). In conclusion, for effective prevention of the LBP at work site, appropriate improvement of work posture and various psychological factors should be considered.

This paper evaluates the current state of work-related musculoskeletal disorders of Korean farmers. Korean farmers are exposed to a multitude of ergonomic risk factors, and have high rates of musculoskeletal disorders such as backpain and knee osteoarthritis, while hip osteoarthritis is relatively low. As of 2010, the average age of Korean farmers is 62.3, and the average period of their work in agriculture is 33.3 years. Therefore, it is difficult to distinguish the influence of natural aging and farm work on the development of musculoskeletal disorders. It is necessary to conduct research on a correlation between specific diagnosis such as rotator cuff syndrome, and farm work in general because farmers complain of a great deal of pain.

BACKGROUND: Bilateral interruption of the upper thoracic sympathetic chain at T2 level represents a selective cure for essential hyperhidrosis. Following the surgical sympathectomy, significant changes in pulmonary function has been observed. Our hypothesis was that thoracic sympathectomy may increase airway resistance during mechanical ventilation and which may be attenuated by the anticholinergics. METHODS: 21 patients with essential hyperhidrosis in ASA physical status class 1 under going thoracoscopic sympathectomy, they were randomizely divided into two groups: glycopyrrolate premedication group (n=13) and non-premedication, control group (n=9). Glycopyrrolate 0.2 mg was administered 30 minutes before the induction of anesthesia. Blood pressure, heart rate, peak airway pressure, plateau pressure were measured at before and immediate after sympathectomy. Respiratory compliance and resistance were calculated. RESULTS: After thoracoscopic sympathectomy, there was significant increase in mean peak airway pressure (15 +/- 3 vs 18 +/- 3 cmH2O, P<0.05) and decrease in respiratory compliance (52 +/- 12 vs 45 +/- 10 ml/cmH2O, P<0.05) compared to baseline. However there was no significant difference between glycopyrolate premedication group and non-premedication group. Conclusion: Thoracoscopic upper dorsal sympathectomy in patients with essential hyperhidrosis causes increase peak airway pressure and decrease the compliance of respiratory system during mechanical ventilation.

OBJECTIVES: The investigation of the degree of the relationship according to body part between occupational stress and musculoskeletal symptoms in the neck, shoulder, elbow, and hands of workers performing computer tasks. METHODS: In August and September 2009, we conducted a survey of 529 public office workers employed by the National Health Insurance Corporation using structured questionnaires in order to find demographic factors, work related factors, job stress, physical computer task load and musculoskeletal symptoms. Nordic musculoskeletal questionnaire, Quick DASH (Disabilities of the Arm, Shoulder and Hand Score), and the Northwick Park neck pain questionnaire were all used to evaluate their musculoskeletal symptoms. The presence of symptoms segregated by body part determined the dependent variables. The degree of job stress and other confounder variables determined the independent variables. We calculated the odds ratio employing multiple logistic regressions. RESULTS: A score of > or =5 in the VAS (Visual Analogue Scale) 10-point scale and the presence of symptoms lasting at least 1 week determined the musculoskeletal symptom group in regards to the Nordic musculoskeletal questionnaire. The neck pain odds ratio was adjusted by sex, age, work hours, employment duration, physical computer task load and depression. It was determined to be 2.92 (95% CI 1.76~4.84) in the higher to lower occupational stress group. The shoulder pain odds ratio was 1.96 (95% CI 1.18~3.24), elbow pain 0.55 (95% CI 0.21~1.43), and hand pain 1.71 (95% CI 0.99~2.95). A score of > or =10 in the 100-unit scale determined the musculoskeletal symptom group in regards to the Northwick Park neck pain questionnaire and the Quick DASH. The neck symptom odds ratio was 2.73 (95% CI 1.66~4.49) and the upper extremity symptom figure was 2.18 (95% CI 1.29~3.68). CONCLUSIONS: This study suggests that the relevance between neck and shoulder symptoms and occupational stress was obvious, however the relevance between elbow and hand pain and job stress was not as clear or ambiguous.

OBJECTIVES: This study investigated occupational contact dermatitis in a tire factory, prompted by a long history of complaints of skin ailments by the factory workers. METHODS: Participants (n=160) completed a questionnaire concerning job characteristics and skin symptoms, and received a medical examination. Fifty-four workers with suspected work-related contact dermatitis were chosen for a patch test of contact-related dermatitis. RESULTS: The most frequent positive reactions of patch test were produced by diphenylguanidine, formaldehyde and cobalt. Twenty-one of the 54 individuals (38.9%) were judged to have work-related skin disease. CONCLUSIONS: Exposure to natural and synthetic rubbers and additive materials pose a risk of contact dermatitis in a tire manufacturing environment. Improved sanitary work practices and public health awareness measures are suggested.
