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 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.

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.

OBJECTIVES: The goals of the study were to compare the middle ear (ME) volumes from both normal and lesioned ears, and these ME volumes were measured by a digital image processing computed tomography (CT) program in patients with unilateral chronic otitis media, and we wanted to compare the ME volumes of the lesioned ears by comparing the ME volumes obtained by tympanometry with those ME volumes measured by the digital image processing CT program. METHODS: Forty-four patients who had unilateral chronic otitis media (COM) and contralateral normal tympanic membranes (TM) and 100 subjects with normal TMs were included in the study. The normal volumes of the external auditory canal (EAC) were measured in the normal group. The tympanometric ME volumes in the ears with a perforated TM were calculated as the difference of the tympanometric volumes measured from the both ears in patients with unilateral COM. The CT ME volumes were measured by a digital image processing program. RESULTS: The tympanometric volumes of the EACs in the ears with normal TMs were 1.4+/-0.3 mL. There were no significant differences according to gender, age and the side of the face the ear was on. The tympanometric volumes of the EAC in the normal-side ear of the patients with unilateral COM showed no significant differences when compared with those from the normal group. The ME volumes of the intact ears, as measured by CT, showed significantly higher values than those ME volumes of the lesioned ears. The ME volumes of the lesioned ears, as measured by tympanometry, showed a strong, significant linear correlation with those ME volumes calculated by CT; however, the ME volumes of the lesioned ears, as measured by tympanometry (1.5+/-1.4 mL), were significantly larger than those ME volumes measured by CT (1.1+/-0.8 mL). CONCLUSION: Our results show that chronic otitis media causes reduced ME volumes compared to those ME volumes of the contralateral normal ears. Tympanometry can provide a valuable estimation of the ME volumes in chronic ears, although it tends to overestimate the ME volumes, and especially for the ears with a larger ME volume.

OBJECTIVE: The objective of this study was to determine whether complications and nursing interventions during hemodialysis could be reduced by using gradient ultrafiltration(GUF) and high sodium dialysate(HSD). METHODS: Thirty outpatients who had been on hemodialysis for more than 3 months were enrolled. Patients received Conventional HD(Na+ 137 mEqX4 hrs, constant UF), GUF(UF 62.5%X2 hrs, UF 37.5 %X2 hrs), HSD(Na+ 145 mEqX2 hrs, Na+ 140 mEqX2 hrs) and HSUF(GUF and HSD). Each methods were prescribed for 2 weeks. The clinical features such as thirst, interdialytic weight gain, postdialytic weight loss and MAP(mean arterial pressure) and the frequency of intradialytic complications and nursing interventions were evaluated. RESULTS: The results were as followings. Interdialytic thirst, weight gain, postdialytic weight loss and MAP(pre/post HD) were not significantly different in each method. On the other hand, there was significant difference between 4 methods in serum sodium, osmolality and Hct. There were significantly fewer episodes of hypotention, muscle cramp and headache when using GUF, HSD and HSUF than CHD. The number of nursing interventions was significantly reduced in GUF, HSD and HSUF than CHD. CONCLUSION: Hemodialysis with gradient ultrafiltration and high sodium dialysate leads fewer complications and nursing interventions, more patient's well being.
