PURPOSE: The construction worker has diverse harmful factors such as noise, dust, and dealing with chemicals. Therefore this research aimed to examine the necessity of appointing a health manager in the construction industry by examining the cost-benefit analysis when the construction industry appoints a health manager. METHODS: In order to calculate the healthcare staff employment cost and the benefits from their activities in 1,425 construction companies with the staff of 300 or more people during 2011, this study analyzed existing data and existing research data, as well as national data. RESULTS: Total annual costs were 99,920,070,900 won and total annual benefits were 324,807,182,625 won. Benefits were found to be 224,887,111,725 won exceeding costs. Benefit/cost ratio resulting from appointing a health manager in the construction industry workplaces was 3.25 times. CONCLUSION: The findings of this research can be used as the base data to make rational decision to positively encourage the employment of healthcare staff in construction companies pursuant to relevant laws.

BACKGROUND: The bronchial anthracofibrosis has been thought to be a unique clinical syndrome caused by a fibrotic response to active or old tuberculous infection, but recent studies suggest that long-term exposure to woodsmoke may be the cause of the development of bronchial anthracofibrosis and the tuberculosis is thought to be a disease frequently associated with bronchial anthrocofibrosis, not the main etiology. The purpose of this study was to elucidate the relationship between the bronchial anthracofibrosis and the long-term exposure to woodsmoke and tuberculosis through analyses of the clinical features of patients with bronchial anthracofibrosis. METHODS: 166 patients having bronchial anthracofibrosis confirmed by bronchoscopy were included in this study. They were 23 males and 143 females, having mean sge 72.4 years, ranging from 56 to 91. The epidemiologic features, distinctive clinical features, physiologic findings, radiologic findings and bronchoscopic findings were analyzed retrospectively. RESULTS: All the patients living in rural area (129 of 166) had experienced long-term exposure to woodsmoke. The history of tuberculosis was obtained in 52 patients without history of occupational exposure to dust. The predominant chest CT findings were atelectasis, bronchial stenosis and calcified or noncalcified lymph node enlargements. The most common abnormality of pulmonary function was obstructive pattern, observed in 47.8%. The bronchoscopic examination disclosed multifocal anthracotic plaques mostly at the bifurcation of lobar or segmental bronchi, particularly in upper lobe. The bronchial stenosis was frequently observed in right middle and upper lobe. The associated diseases were obstructive airway disease in 56, obstructive pneumonia in 40, active tuberculosis in 36, and lung cancer in 11 patients. CONCLUSION: The bronchial anthracofibrosis, in the patient who has long-term experience to woodsmoke inhalation without any history of environmental exposure to dust, is one of the manifestation of lung disease related to woodsmoke inhalation, and is frequently associated with various pulmonary diseases, including tuberculosis.

PURPOSE: To assess the clinical and radiological results of mobile bearing total knee arthroplasty using the LCS system and to analyse complications arising. MATERIALS AND METHODS: From Oct. 1992 to Dec. 1998, 135 cases of total knee arthroplasty was performed using the LCS mobile bearing system. Among those are evaluated 108 cases which were followed up for a mean of 4.8 years (3-9.2 years). Retrospective analysis was done by the clinical and radiological evaluations usinga ROM, tibio-femoral alignment, HSS score and radiological loosening. RESULTS: The preoperative mean HSS score (58.6) was improved to 89.5 at final follow up. Tibio-femoral angle changed from a varus of 3 degrees to a valgus of 5 degrees. Arc of motion was reduced from 121 degrees to 116 degrees in osteoarthritis and increased from 111 degrees to 118 degrees in rheumatoid arthritis. There were 16 cases of osteolysis, but no case provoked clinical problems or more than 4 points in the radiolucent score. Complications were one polyethylene dislocation and one intraoperative tibia plateau fracture. CONCLUSION: Mobile bearing knee system showed excellent and predictable clinical and radiological results at a mean 4.8 years follow-up.

PURPOSE: To analyze the results and complications arising from 1,000 cases of primary total knee arthroplasty (TKRA), as performed by one surgeon. MATERIALS AND METHODS: From February, 1992 to June, 2000, 1,000 cases of primary TKRA were performed by a single surgeon. Among the 1,000 cases, 573 cases followed up for more than one year (average 2.9 years) were evaluated try allocating special surgery (HSS) scores and by determining the range of motion (ROM), and presence of complications retrospectively. RESULTS: There were 872 cases of primary osteoarthritis, 70 cases of rheumatoid arthritis, 32 cases of osteonecrosis, and 26 cases of miscellaneous diseases. The HSS score increased from 57.8 preoperatively to 90.4 postoperatively, ROM increased from 111degrees to 113degrees and flexion contracture decreased from 9degrees to 2degrees, but no statistical differences in results were observed between diseases. Common causes of complications were superficial infection (3.6%), deep infection (2.4%) and deep vein thrombosis (1.8%). Two patients died, one due to myocardial infarct and the other due to an unknown etiology. Revision arthroplasties were performed in 19 cases. CONCLUSION: After primary TKRA, ROM and functional score improved satisfactorily. No statistical differences were apparent between diseases. Infection was the most common complication.

BACKGROUND AND OBJECTIVES: It has been reported that vibration applied either on the mastoid or the sternocleidomastoid (SCM) muscles induces nystagmus in patients after unilateral vestibular neuritis. The aims of the study were to characterize the vibration-induced nystagmus (VIN) in patients with various vestibular disorders and to compare the results of VIN to unilateral weakness in caloric test. MATERIALS AND METHODS:Fifthy-four patients with Meniere's disease, 58 patients with unilateral vestibular neuritis, 170 patients with migraine-associated dizziness, and 78 patients with chronic recurrent vestibulopathy were included. We recorded eye movements during unilateral 100-Hz vibration on the mastoids and SCM muscles. The bithermal caloric test was also performed. Abnormal criteria of VIN were slow-phase slow-phase velocity (SPV) at 4 all different conditions > or = 2degrees/s with the same directions or mean of SPV at vibration on both mastoids or both SCM muscles > or = 5degrees/s with the same directions. RESULTS: In Meniere's disease, 28 of 57 (49.1%) of patients show pathologic VIN, 21 of 57 (36.8%) show pathologic canal paresis. 14 of 57 (24.6%) show abnormalities in both tests, and 35 of 57 (61.4%) show any abnormalities in either test. In unilateral vestibular neuritis, 43 of 58 (77.6%) showed pathologic VIN, 58 of 58 (100%) show canal paresis. In migraine-associated dizziness, 48 of 170 (28.2%) showed pathologic VIN, 58 of 170 (18.8%) show canal paresis. 15 of 170 (8.8%) showed abnormalities in both tests, and 65 of 170 (38.2%) show any abnormalities in either test. In chronic recurrent vestibulopathy, 23 of 78 (29.5%) of patients show pathologic VIN and 17 of 78 (21.8%) show pathologic canal paresis. Seven of 78 (9.0%) showed abnormalities in both tests, and 33 of 78 (42.3%) show any abnormalities in either test. CONCLUSION: VIN test can increase the sensitivity in detecting vestibular imbalance in vestibular disorders when combined with caloric test.

BACKGROUND AND OBJECTIVES: It has been reported that vibration applied either on the mastoid or on the sternocleidomastoid (SCM) muscles induces nystagmus in normal subjects. The aims of the study were to characterize the direction and velocity of slow-phase eye movement which is induced by vibration in normal subjects and to propose the mechanism of vibration-induced nystagmus (VIN) in normal subjects. MATERIALS AND METHOD: We recorded eye movements during unilateral 100-Hz vibration on the mastoid bone and SCM muscles in 56 normal subjects. The subjects were divided into 4 groups in ages (20s, 30s, 40s, 50~60s). The directions of VIN, the degree of maximal slow-phase eye velocities were analyzed according to age. Positive value means slow-phase velocity (SPV) to the right side. RESULTS: In 20s, vibration on right/left mastoids induced SPV of 1.2+/-2.0degrees/sec, 0+/-2.1degrees/sec and on right/left SCM muscles, 1.1+/-1.9degrees/sec, -1.2+/-2.5degrees/sec. In 30s, vibration on right/left mastoids induced SPV of 3.3+/-3.8degrees/sec, -0.3+/-1.4degrees/sec and on right/left SCM muscles, 2.8+/-4.2degrees/sec, -1.0+/-1.5degrees/sec. In 40s, vibration on right/left mastoids induced SPV of 0+/-1.7degrees/sec, -0.2+/-1.2degrees/sec and on right/left SCM muscles, 0+/-1.8degrees/sec, 0+/-1.0degrees/sec. In 50~60s, vibration on the right/left mastoids induced SPV of -1.3+/-1.3degrees/sec, 1.2+/-1.3degrees/sec and on right/left SCM muscles, -0.6+/-0.9degrees/sec, 0.9 +/-1.5degrees/sec. The directional preponderance of the slow-phase eye movement to the vibrated side was statistically significant in 20s and 30s, however, the preponderance of the slow-phase eye movement changed into the non-vibrated side in 50~60s. CONCLUSION: The proprioceptive input, changing major rotator from the inferior oblique muscle to the sternocleidomastoid muscles might explain the change of the directional preponderance of the slow-phase eye movements in normal subjects according to ages. Although this directional preponderance is not consistent in all age groups, it is still important in discriminating normal responses from abnormal responses which can be induced by vibration.
