Objectives . A cross sectional study was carried out in the welders exposed to manganese and control group. The aim of this study was to assess the adverse effects of manganese on central nervous system of welders. Methods : The study group consisted of 49 welders and the reference group, 49 workers matched with welders for age and educational level In automobile manufacturing company. Concentration of manganese in welding huge, in blood, and cumulative exposure index (CEI) were determined for each subject. For each group, computerized neurobehavioral test including Simple Reaction Time, Digit Symbol, Digit Span, and Finger Tapping Speed of Swedish Performance Evaluation System were applied. Results : Exposure level of manganese in welders were very low (mean CEI, 0.069) . Welders exposed to manganese had slower response speed, slower motor steadiness, and shorter memory span than control group. But these differences were not statistically sign nificant. The performance of Finger Tapping Speed tended to lower as environmental and biological exposure index got higher, Other neurobehavioral tests were found to have a little association with the exposure indices. Conclusions . There was no significant difference of neurobehavioral performance between welders and control group. This study indicates that Finger Tapping Speed mea suring motor steadiness might be a one of useful tests for early detection of adverse effects of welding on central nervous system.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

Background and Objectives: Lower urinary tract injuries in pelvic bone fracture can lead to significant complication. We tried to find out the relationship between the fracture location and the bladder, urethra injury in patients who sustaining pelvic bone fracture. We thought that the fracture locations could serves as markers for injury. Materials and Methods: A clinical study was made on 43 patients who sustaining pelvic bone fracture with bladder or urethra injury in the Chosun University hospital during the period of 5 years from January, 2002 to December 2006. Diagnosis was done by retrograde cystography, retrograde urethragraphy, abdomenpelvic computed tomography. Results: Of the 43 patients reviewed, 27 patients had intraperitoneal type bladder rupture, and 12 patients had extra-peritoneal type bladder rupture. 9 patients had urethral rupture. Intraperitoneal type bladder rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum. but the statistically significance is abscent (p= 0.642). Also extraperitoneal type bladder rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum. but the statistically significance is abscent (p= 0.548). And all type bladder rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum. but the statistically significance is abscent (p= 0.775). And urethral rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum but the statistically significance is abscent (p= 0.528). Lastly, Combineded bladder rupture and urethral rupture cases are most commonly associated with infrapubic ramus, llium, Symphysis pubis. But the statistically significance is abscent (p= 0.462). Conclusions: In our study when there is a pelvic bone fracture, the fractured site of pelvic bone have no statistically association with lower urinary tract injury. But most common pelvic bone fracture site of all lower urinary tract injury cases is infrapubic ramus. Therefore, if infrapubic ramus fracture is found in the condition of pelvic bone fracture, it is highly likely to have lower urinary tract injury. More careful observation and diagnosis is necessary for this case.

Gradient Model Load Balancing 기법에 대한 분석

황대준 成均館大學校 科學技術硏究所 1988 論文集 Vol.39 No.1

In this paper, we analysed Lin's^1) Gradient Model dynamic load Balancing Scheme, in which the states of system and processing elements are described by the low-, and high-threshold, and showed that it has serious drawbacks in global load balancing. To address the limitation of Lin's model and more generalize it, we proposed a new dynamic load balancing scheme, the Extended Gradient Model, in which the dynamic threshold, D_t, is used as the state variable, and made critical assesments on both EGM model and GM model.

목적: 신축초등학교와 대조학교를 선정하여 교실 내 포름알데히드와 TVOCs를 측정하고 컴퓨터 신경행동검사를 이용하여 실내공기 오염물질이 학생들의 인지기능에 미치는 영향을 평가하였다. 방법: 신축초등학교 5학년 71명을 실내공기 오염물질 노출군으로 하고, 개교한지 12년째인 대구시의 일개 초등학교 5학년 2학급 63명을 대조군으로 하여 실내공기 오염물질농도 측정 및 컴퓨터 신경행동검사를 실시하였다. 결과: 신축학교에서 의도적으로 창문을 개방한 학급에서 1교시 포름알데히드 농도는 34.6 ㎍/㎥, 4교시에는 27.3 ㎍/㎥, 창문을 개방하지 않은 학급에서 1교시 80.2 ㎍/㎥, 4교시 127.1 ㎍/㎥, 대조학교에서는 2학급 각각 1교시에 12.6 ㎍/㎥, 7.5 ㎍/㎥, 4교시에 19.8 ㎍/㎥, 25.2 ㎍/㎥였다. TVOCs의 경우 신축학교의 의도적으로 창문을 개방한 학급에서 1교시에 농도는 487.2 ㎍/㎥, 4교시에 428.2 ㎍/㎥, 창문을 개방하지 않은 학급에서 1 교시에 농도는 1,283.5 ㎍/㎥, 4교시에 1,715.4 ㎍/㎥, 대조학교의 경우 2학급에서 각각 1교시에 농도는 240.9 ㎍/㎥, 150.8 ㎍/㎥, 4교시에 농도는 371.9 ㎍/㎥, 448.0 ㎍/㎥였다. 부호숫자 짝짓기의 평균반응시간은 대조학급이 1교시에 2,585 msec에서 4교시에 2,459 msec으로 감소한 반면 신축학교의 창문을 의도적으로 개방한 학급은 2,343 msec에서 2,510 msec으로, 평소대로 수업한 학급은 2,340 msec에서 2,563 msec으로 반응시간이 각각 167 msec, 223 msec 증가하였다. 1교시의 부호숫자 짝짓기 의 반응시간을 100%로 했을 때 창문을 의도적으로 개방 한 학급은 4교시에 5.9% 증가하였고(p<0.01), 평소대로 수업한 학급은8.3% 증가하였다(p<0.01). 반면에 대조학급은 4교시에 5.0% 감소하였다(p<0.01). 결론: 향후 학교의 실내공기질의 안전성 평가는 샘플링 된 공기의 오염수준의 측정뿐만 아니라 학생들의 건강영향도 함께 고려되는 것이 바람직할 것이다. Objectives: Most studies on the indoor air quality of newly built schools have focused only on the number of schools exceeding a standard or on subjective symptoms, such as sneezing, irritated eyes and an irritated nose. However, there has been no report on how poor indoor air quality affects children's academic performance. This study evaluated the effects of indoor air quality on the neurobehavioral performance of elementary school children. Methods: This study measured the indoor air pollutants and compared children's performance, using a computerized neurobehavioral test, between a newly built and a 12-year-old school. In addition, a questionnaire was administered regarding the indoor air quality related symptoms of children in a newly built and a 12-year-old school. Results: In the newly built school, the formaldehyde levels in the 1^(st) and 4^(th) classes with an open window were 34.6 and 27.3 μg/㎥, respectively. The levels in the 1^(st) and 4^(th) classes with the window closed were 80.2 and 127.1 μg/㎥, respectively. In the 12-year-old school, the formaldehyde levels in 1^(st) and 4^(th) class with open and closed window were 12.6 and 7.5 μg/㎥, and 19.8 and 25.2 μg/㎥, respectively. With respect to total volatile organic compounds, the levels in the 1^(st) and 4^(th) classes with the window open in the newly built school were 87.2 and 428.2 μg/㎥, respectively. In the 1^(st) and 4^(th) classes with the window closed, the total volatile organic compounds were 1,283.5 and 1,715.4 μg/㎥, respectively. In the 12-year-old school, the total volatile organic compounds were 240.9 and 150.8 μg/㎥, and 371.9 and 448.0 μg/㎥ in the 1^(st) and 4^(th) classes, respectively. In the case of a newly built school, the performance of the students in the neurobehavioral test in the 4^(th) class with the window closed was 8.3% lower than for those in the 1^(st) class with the window closed, but was only 5.9% lower when the windows were open. There was a statistical significant difference in the total numbers of symptoms between the two schools. Conclusions: These results suggest a proper evaluation of the indoor air quality within schools is required into both the level of contamination and the health effects of these contaminants toward children.
