이현재,손지언,,홍영습,,이영일,예병진,유창훈,정갑열,김상훈,임형준,장은철,김정만,김준연 大韓産業醫學會 2006 대한직업환경의학회지 Vol.18 No.2

목적: 석면에 노출된 근로자에서 석면관련 폐질환의 양상을 분석하고 진단에 있어 HRCT의 유용성을 연구하여 석면에 대한 의학적 감시프로그램의 개발에 기여하고자 하였다. 방법: 석면에 직접 노출되는 작업자 68명과 간접 노출되는 작업자 94명 등 총 162명에 대해 OSHA 석면 표준, 의학적 감시 프로그램에 따라 단순 흉부방사선검사, 폐활량검사 및 우리나라 실정에 맞게 일부 수정한 의학적 설문지를 통해 면접조사의 방식으로 환자에 관한 정보를 수집하였으며, 자료의 신뢰성을 확보하기 위하여 면접조사는 1달 이상의 기간을 두고 2차례에 걸쳐 실시된 후 확인, 수정하였다. 또한, 석면관련 폐질환을 확진하기 위하여 HRCT를 추가적으로 실시하였다. 결과: HRCT결과 석면관련 폐질환의 유병율은 162명의 근로자중 17명으로 10.5%였는데, 직접 노출군에서 10명 (14.7%), 간접 노출군에서 7명 (7.4%)이었다. HRCT와 비교할 때 단순 흉부방사선검사의 민감도와 특이도는 각각 70.6%와 98.6%이었고, 양성 예측도와 음성 예측도는 각각 85.7%와 96.6%으로, HRCT는 단순흉부방사선검사에 비해 민감도가 높아 초기 석면관련 폐질환을 진단하는데 효과적이었다. 석면관련 폐질환의 진단에 있어 HRCT와 폐활량검사 사이에 유의한 관련성이 관찰되었다. HRCT 결과 석면관련 폐질환의 유무와 의학적 설문조사 결과의 빈도분석을 실시한 결과, 유의한 변수는 작업기간, 흡연량, 호흡기질환의 과거력, 기침, 호흡곤란이었다. 결론: HRCT는 석면관련 폐질환의 진단에 있어 단순 흉부방사선검사와 비교하여 민감도가 높아 초기 진단에 유용하므로 단순 흉부방사선선검사 결과 석면관련 폐질환소견을 보일 때뿐만 아니라, 정상소견을 보이더라도 폐활량 검사결과와 근무력, 흡연력, 호흡기질환의 과거력, 기침, 호흡곤란 등의 호흡기 증상을 참고하여 HRCT검사를 고려해야 한다. 또한, 본 연구에서 관련성이 없었던 요인들에 대해서도 향후 연관성을 규명하는 광범위한 전향적 연구가 필요하다. Objectives: This study was carried out to improve the medical surveillance program of workers exposed to asbestos by examining the usefulness of High Resolution Computed Tomography (HRCT) in the diagnosis of asbestos-related lung disease. Methods: The study subjects comprised 162 workers in a ship-repairing yard, 68 of whom had been directly exposed to asbestos and 94 indirectly exposed. The 'Occupational Safety & Health Administration (OSHA) asbestos standard, medical surveilance program' and HRCT were conducted to analyze the aspects of the asbestos-related lung disease. The OSHA asbestos standard, medical surveilance program consists of simple chest x-ray, spirometry and medical questionnarie. Results: Seventeen (10.5%) of the 162 subjects, 10 (14.7%) directly exposed and 7 (7.4%) indirectly exposed, revealed asbestos-related lung disease on HRCT. The sensitivity and specificity of simple chest x-ray for asbestos-related lung disease were 70.6% and 98.6%, and the positive and negative predictive values were 85.7% and 96.6% respectively, as compared with HRCT, HRCT was an effective diagnostic tool especially to detect early asbestos-related lung disease. The study results indicated a relative significant association between the results of spirometry and HRCT. The variables significantly associated with asbestos-related lung disease on HRCT were work duration, smoking history (pack-years), past history of respiratory disease, cough and dyspnea. Conclusions: In the diagnosis of asbestos-related lung disease, HRCT should be considered not only for workers with positive findings on simple chest x-ray, but also workers with specific findings on spirometry, occupational history, smoking history, and past history of respiratory disease, or with respiratory symptoms such as cough and dyspnea.

Statistical analysis of renal inpatients admitted to the department of pediatric ward of Chungnam National University Hospital from 1978 to 1988 was performed according to their annual incidence of each disease, disease pattern, and age distribution. Renal diseases were found in 628(6.16%) among 10,194 total inpatients from 1978 to 1988. Male to famale ratio of renal disease was 1.99 to 1. Annual incidence of acute glomerulonephritis was decreased but no significant change was noted in the incidence of nephrotic syndrome and urinary tract infection. Acute glomerulonephritis was the leading cause of admission in all age groups and it constituted 28.82% of total renal patients. It was followed by nephronic syndrome(23.24%), urinary tract infection(16.56%). Wilms’ tumor(7.64%), Henoch-Schonlein nephritis(6.21%), and recurrent hematuria(4.45%). Urinary tract infection showed relatively high incidence in infancy and acute glomerulonephritis and nephrotic syndrome were high in older age group. Renal diseases were most frequently found in 7-9 years old age group. Chronic renal failure and recurrent hematuria were relatively frequent in over 12 years old age group.

The determination of an optimal and economical coagulant dosage is a crucial problem in water treatment plants: low dosage generally yields a poor removal of raw water turbidity, whereas high dosage leads to sludges which are difficult to dewater. Existing dosage control methods such as jar test, computer controlled equation, zeta potential measurement have shown some limitations in the control of coagulation process. Recent trend of dosage control technology in the developed country is the use of SCD(Streaming Current Detector). SCD is an equipment which continuosely detects the surface charge of particles which are subject to vary with the addition of coagulant. In this study, a technique using SCD is tested and evaluated for the possible control of coagulation process in a water treatment plant. In a bench scale test, the method using jar test is compared with SCD method. Some advantages and disadvantages of SCD are discussed and sensitivity of SCD reading to several water quality parameters is examined. In a pilot scale test using a rapid mixing unit, both SCD and zeta meter reading are measured and compared. Both readings gave similar trends as the coagulant dosage, however, SCD is proven to be more useful because it can be measured on-line. Finally, in a full scale test, SCD is measured at an operating water treatment plant. SCD has the capability of detecting the variation of water quality as well as some problems resulting from clogging of sensors. Overall, SCD technique is proven to be useful and to give some scientifically sound basis for optimum coagulant control in a water treatment plant.

The purpose of this study is to define the spatial approach and aesthetic analysis in architecture since modern period. The essential meaning of architecture requires to be approached with empirical factors which has influences on architects, that is its intrinsic specialty of scientific practicality and aesthetic aspects. Especially when the peculiarities of architecture is understood with the view considering it as an art, it will be the concept of the space. Now, the study on architecture can be started with the aesthetic attitude which recognized it as the art of the space. It is on the premise of the change of the aesthetic recognition in architecture that its essence and central concept are in the space, its function and forms, and aesthetical embodiment. It is not until the late 19th century that the concept of the architectural space has been adapted and it has been changed showing various aspects through the 19th and 20th century. Therefore the periodical scope of this study is defined from the late 19th century until now. The conclusions of the study as per the above mentioned purpose and intentions are as follows ; The structure of the architectural space expressed as per the aesthetic recognition of the space shows the transforming aspects from the Enclosed Spatial Structure to the Topological Spatial Structure. And the aesthetic cognition viewpoint of the architectural spaces is classified as the objective speculating aesthetics where the subjects' transcendental cognition is developed subjectively as well as individually, and the objective empirical aesthetics in which the subjects' experience is working objectively and logically.

von Willebrand's disease (vWD) is the most common autosomal-dominant inherited disorder resulting from a quantitative or a qualitative defect of von Willebrand factor (vWF). The most diagnostic pattern is the combination of a prolonged bleeding time, a reduction in plasma vWF concentration, a parallel reduction in ristocetin cofactor activity, and reduced factor Ⅷ activity, In this case, ristocetin-induced platelet aggregation data were compatible with that of vWD. Bleeding times were prolonged over 4 minutes, vWF antigen levels were 45%. vWF ristocetin cofactor activities were 0~1% and factor Ⅷ levels were 31%, when compared to the normal control. We report the case of a family with vWD. characterized by a quantitative defect in vWF
