In order to work out a more effective method of guiding those physically-handicapped students whose practical physical traning has been neglected in their regular courses so far, I conducted an investigation, through questionnaires and interviews, into the training situation of 33 college students who are physically handicapped, and the guiding conditions of those professors who are leading their respective physical education department in 26 universities and colleges sellected for this study. I combined and analized the data which have resulted from my investigation, such as those about how the physically-handicapped students are actually trained and dealt with, and what are their requirements, etc. The results attained are as follows. 1. The physically-handicapped students should in no way be excluded from their regular activities of developing their physical abilities. 2. They should be given an ample recognition that the effect of rehabilitation is possible by means of physical activities. 3. The professors in charge of those students should be careful enough not to deal with them with prejudice and any fixed idea. 4. The most effective exerdise available for them is thought to be the individual one which mainly calls for the use of the upper half of their bodies. 5. The practical physical training, aiming at developing the physical abilities of the handicapped students, should be given to them in close consideration of their individual circumstances, to ave them adjusted and accustomed to one or two types of physical exercise as their daily activities. 6. they may as well be given individual training, although it is desirable to let them equally join their regular classes.

The interactions of various carcinogens, such as polyaromatic hydrocarbons, dimethylaminoazobenzene(DAB) and its derivatives and benzacridines with deoxyribonucleic acid(DNA) were investigated by means of second-order perturbation method. The most probable orientations of molecular complex between DNA-base pairs and carcinogen were defermined by the quantity of charge transfer from adenine-thymine pair (A=T pair) to carcinogen and from Guanine-Cytosine pair (G≡C) to carcinogen. It was found that the quantity of charge transfer from thymine part of A=T pair to carcinogen was considerably larger than that from guanine part of G≡C pair to carcinogen. A good parallelism was alos found between the quantity of charge transfer and experimenental carcinogenic activity.

목 적 : 장티푸스는 체액의 세균배양검사에서 Salmonella typhi의 분리로 확진하지만 조기진단을 위해서는 혈청학적인 검사가 도움이 된다. 저자 등은 1989년 이후 장티푸스진단에 S. typhi의 Vi항원을 이용한 간접형광항체법 (Vi-indirect fluorescent antibody test : Vi-IFAT)을 도입하였다. 이에 지난 7년간의 검사결과를 토대로 Vi-IFAT의 민감도 및 특이도를 규명하고자 하였다. 방 법 : 1989년부터 1996년까지 연세대학교 의과대학 세브란스 병원에 발열을 주소로 내원하여 Vi-IFAT가 의뢰된 환자 중 발열의 원인이 확진된 744명의 환자를 대상으로 하였으며, Vi-IFAT에 있어서 양성반응은 1:64이상으로 하였다. 결 과 : 1) 세균배양검사에서 확진된 장티푸스 환자 178예 중 168예에서 양성반응을 보여 민감도는 94.4%이었다. 항체가는 1:64가 89예, 1:128이 36예, 1:256이 27예, 그리고 1:512가 16예이었다. 위음성이었던 10예의 항체가는 1:32가 7예, 1:16이하가 3예이었다. 2) 발열을 주소로 내원한 환자 중 장티푸스 이외의 다른 질환으로 확진된 566예 중 538예에서 음성반응을 보여 특이도는 95.1%이었다. 항체가는 1:32가 117예, 1:16이하가 421예이었다. 위양성이었던 28예의 항체가는 1:64가 23예, 1:128이 5예이었으며, 장티푸스 이외의 살모넬라증이 4예, 요로계감염이 10예, 소화기계감염이 6예, 호흡기 계감염이 5예, 악성 종양이 2예, 그리고 바이러스 감염이 1예이었다. 3) Vi-IFAT 양성인 196예 중에서 장티푸스는 168예로 양성예측율은 85.7%이었으며, Vi-IFAT 음성인 548예 중 장티푸스 이외의 발열질환은 538예로 음성예측율 98.2%이었다. 4) 배양검사와 Widal test 사이의 일치율 (Kappa value)는 0.28로 poor agreement를 보였으며 Vi-IFAT와 Widal test 사이의 Kappa value는 0.74로 good agreement를 보였다. 그러나 배양검사와 Vi-IFAT 사이의 Kappa value는 0.86으로 excellent agreement를 보여 일치율이 가장 높은 검사는 배양검사와 Vi-IFAT라 할 수 있겠다. 5) 장티푸스 환자에 있어서 Vi-IFAT의 양성율은 발열기간이 1중 미만인 환자에서는 68%, 1내지 2주인 환자에서는 89.5%, 2주이상인 환자에서는 100%이었다. 결 론 : Vi 항원을 이용한 간접형광항체법 (Vi-IFAT)은 장티푸스 진단에 높은 민감도 및 특이도를 가지며, 또한 조기진단에 있어서도 임상적으로 유용함을 확인할 수 있었다. Background : Typhoid fever is diagnosed by culture or serological study. The confirmative diagnosis of typhoid fever is made by culture of the causative organism usually from body fluids. Serological test is a supportive diagnositic tool, which is useful for early diagnosis. In Severance Hospital, Vi-indirect foluorescent antibidy test(Vi-IFAT) using the Vi-antigen of Salmonella typhi has been used in the diagnosis of typhoid fever since 1989. We investigated the test results from the past 7 years, in order to clarify the sensitivity and specificity of Vi-IFAT. Methods : A retrospective study was done on patients whose chief complaint was fever and who were tested using Vi-IFAT in the Severance Hospital from 1989 to 1996. The positive value for Vi-IFAT was defined as 1:64 or higher. Results : The sensitivity and specificity of Vi-IFAT for typhoid fever was 94.4% and 95.1%, respectively. The positive and negative predictive values were 85.7% and 98.2% respectively. Positive rates of Vi-IFAT after fever onset increased with time and 68% were positive before the first week. From the first to the second week, 89.5% were positive and after the second week, 100% were positive. Conclusion : Vi-IFAT is not only a valuable serologic test for the diagnosis of typhoid fever, but also useful in the early diagnosis of the disease.

정용호,박병윤,손장열 대한건축학회 2004 대한건축학회논문집 Vol.20 No.7

Air filters of air conditioning system play a main role in improving indoor air quality. However there is not enough information about air filters and any official maintenance standards or guidelines for air filters in Korea. The aims of this study are proposal for air filter test methods after installation and basic data about air filter maintenance guidelines or standards. In this study, arrestances, pressure losses and microorganisms between the upstream and the downstream of air filters were measured with digital dust indicators, a micro manometer and blood agar plates. Measurements were conducted before and after washing out pre filters and outdoor air untake ratio varied between 10%, 20% and 30% under actual operating conditions. The results of this study is as follows. Arrestance increased depending on whether the input of outdoor air was added. However some cases did not follow the trend. Pressure loss decreased depending on whether the input of outdoor air was added to AHUs which have built-out type return fans and vice versa in the built-in type. In contrast, the colony counts of microorganisms increased in the downstream of air filters. The rates of increase dropped depending on the addition of the input of OA. Arrestance increased, pressure loss decreased and the rates of increase of microorganisms dropped after washing out prefilters. Medium filter replacement is the main factor for arrestance, prefilter replacement or washing is the main factor for microorganisms but the range of fluctuation in differential pressure was hard to recognize as 1∼4mmAq. As for the results, proper maintenance for air filters, periodical washing out prefilters are important and development air filter performance test methods, standards or guidelines of dust concentration and microorganisms in AHUs after installation are required.

Indoor Air Quality has been significantly degraded due to the improvement of the airtightness of residential and commercial combined high-rise apartment buildings. In order to handle the problems related to insufficient ventilation, the application of mechanical ventilation system is required in detached residences or apartments in the country. As an alternative, air-to-air heat recovery ventilators are used at initial stage for energy conservation using waste heat recovery and the improvement of IAQ in high-rise apartments, currently being more widely used even in apartments and detached residences. Due to this trend, relevant institutes and organizations are making standards for the evaluation of HRV(Heat Recovery Ventilator) performance, but research related to the evaluation of HRV performance are not sufficiently done in this circumstance before applying in real buildings. Therefore, the purpose of this study is to compare and evaluate international and domestic standards for the evaluation of HRV performance, and to provide guideline for the adequate selection of effective HRV by evaluating the performance synthetically in terms of major items.
