Dong-A University Department of Health Care, Handong University Sunlin Presbyterian Hotpital1) Department of Occupational Medicine, College of Medicine, Dong-A University2) 0bjectives : This study was performed to determine the reference values of blood lead, manganese, aluminium, and silicon in healthy adults. Methods : The subjects were 132 (67 male and 65 female), and classified to three age groups (≤39,40∼49, and 50≤). Hood lead, manganese and aluminium were analyzed by atomic absorption spectrophotometer, and blood silicon was analyzed by direct current plasma optical omission spectrometer. Results : Blood lead levels(geometric mean, S.D) were (3.49, 1.70) ㎍/dL in male auld (3.04, 1.65) ㎍/dL in female, but the difference is not significant, and there was no significant difference between age groups. Mean blood manganese level was 0.99±0.41㎍/dL, and there was no significant difference between sex or age groups. Mean blood aluminium level was 0.59±0.35㎍/dL and there was no significant difference between sex or age groups. Mean blood silicon level was 54.41±27.64㎍/dL in male and 43.34±23.51㎍/dL in female, and the level in male was significantly higher than that in female (p〈0.05). There was significant difference between age groups, and the oldest showed the highest level in male (p〈0.05), but no significant difference between age groups in female. Conclusions : Authors hope that this study would provide basic data for determininig reference values and evaluating health effects.

본 연구는 김일의 일생과 업적을 재조명 하는데 그 목적을 두었다. 이를 위해 김일의 회고록, 다큐멘터리, 신문, 잡지, 기사, 동영상 등을 자료로 설정하여 '김일의 일생'과 '김일의 일생이 한국민의 정서에 미친 영향', 그리고 '김일의 스포츠 외교'에 중점을 두고 문헌 고찰하였다. 그 결과는 다음과 같다. 첫째, 김일은 WWA 세계 태그타이틀을 비롯하여 각종 세계 대회의 타이틀을 거머쥐었으며, 그 공로를 인정받아 국가로부터 국민훈장 석류장, 체육훈장 맹호장, 체육훈장 청룡장을 수상하였다. 둘째, 일본과 서양열강들로부터 끊임없는 간섭과 지배를 받아 실의에 빠져있던 우리 국민들은 김일이 경기에서 일본선수들을 강력한 박치기로 쓰러트리고, 서양열강 소속의 선수들을 발차기로 쓰러트리는 모습에 일제에 대한 복수감과 같은 대리만족을 느꼈을 것으로 해석된다. 셋째, 스포츠외교가 활발하지 않은 시점에서 김일이 일본과 한국을 비롯한 여러 국가를 돌아다니며 경기를 하였다. 특히 일본과의 교류를 활발히 가짐으로서 대한민국 엘리트스포츠발전의 일부요인이라고 할 수 있는 일본과의 체육 교류의 물꼬를 틀었다. 본 결과는 김일의 일생과 업적이 대한민국 사회에 일부 영향을 주었다는 것을 시사한다.

Alpha_1-fetoprotein (AFP) test was done by double immunodiffusion method in agar gel, on 41 carinoma of the liver and 92 cases of other various conditions including 28 healthy person, 56 cases of benign diseases of the liver and biliary tract and 8 cases of malignant diseases of the stomach and pancreas admitted during to the Department of Internal Medicine during the past 10 months from Oct., 1971. to July, 1972. The results can be summarized as follows: 1. Among 41 cases of primary carcinoma of the liver, AFP was positive in 51.2% while it was all negative in 92 cases of other various conditions. 2. There was no relationship between AFP positivity and age and sex of the case, of primary carcinoma of the liver. 3. AFP positive reaction was more frequent in the cases who showed a pattern of chronic liver disases by physical examination, liver chemistry and liver scanning than in those who did not. 4) All 5 cases of primary carcinoma of the liver who had bloody ascites showed of AFP positive reaction. 5) There was no relationship between the size of cold area in liver scanning and AFP positivity. 6) The grading of malignant cell by liver cytology revealed no appreciable relationship with the AFP positivity.

Generally, main problem of heterogeneous materials, composed with metal/ceramics, is wide difference of thermal expansion that exists in layers between metal and ceramics. So new materials are developing, so called FGM(Functionally Gradient Materials), that has relaxation of thermal stress and thermal barrier effect.

경희대학교 서울 캠퍼스에 재학중인 학생 211명을 대상으로 그들이 하루 일과를 어떻게 보내는지에 대해서 설문조사를 실시하였다. 학생들은 자신들이 갖는 수업시간, 수업준비시간, 교양독서시간, 운동시간, 대화시간, 오락시간 등을 설문지에 분단위로 기록하였다. 경희대학교 학생들은 하루 평균 약 2시간 40분의 수업을 받는 것으로 나타났으며, 이 수업을 위하여 약 1시간 16분 정도를 준비하는 것으로 나타났다. 놀랍게도, 학생들은 교양독서를 읽으면서 보내는 시간이 약 27분 정도에 지나지 않았으며, 신체적인 운동을 하면서 보내는 시간 역시 13분을 넘지 않는 것으로 나타났다. 본 연구에서는 설문조사의 결과와 시사점을 논의하였다. 211 students in Kyunghee University were questioned on how they spent a day to investigate their everyday life. They were asked the time spent on the lecture-taking lecture-preparation, the autonomous liberal reading, exercise, conversation, pleasure, etc. It was found that on the average the students spent 2 hours 40 minutes a day for the lectures and about 1 hour 16 minutes to prepare them. Surprisingly, they spent only about 27 minutes on the average for autonomous liberal reading. Moreover, they spent less than 13 minutes on physical exercise. The result and implication of this research were discussed.

A garlic harvester attached on tractor with pulling mechanism was developed in the study, based upon a kinematical analysis and related preliminary field tests on the conventional garlic harvesting method. The harvesting efficiency of the developed harvester was more than 80% in the garlic field irrigated before harvesting. The harvesting performance of the harvester was estimated to be about 400 Pyungs/hr in the irrigated field before garlic harvesting. for proper garlic drying and collection, the harvester discharged the harvested garlic on the ground uniformly at the angles of 135˚-150˚ to its forward direction with the garlic blb's placing toward the harvester. In the field test, the forward speed of the harvester ranged approximately from 0.2 m/s through 0.8 m/s. However, it was strongly recommended that the spacing of planting garlic seeds should be standardized in the near future for increasing its harvesting efficiency.

낮은 계수감도를 갖는 IIR 디지탈 필터의 제안

李俊模 관동대학교 1994 關大論文集 Vol.22 No.2

The complexity and accuracy of a finite wordlength implementation of an ideal digital filter depends primarily on the chosen filter structure,on the number of multiplications to be performed,and on the size of the multipliers. As the size of the multipliers depends on both the coefficient and state wordlength,any coefficient quantization will lead to a reduction in digital filter complexity at the expense of accuracy in approximating the ideal behaviour. The amount of possible coefficient wordlength reduction depends on the coefficient sensitivity properties of the digital structure. In this paper,a method is proposed for synthesizing very low multiplier coefficient sensitivity in IIR digital filter. The method applies to the case where the poles of the transfer function of the filter are near Z=1.

의약품은 약물을 생체에 적풋하기 위하여 유효성분의 효과가 언제나 일정하게 확보되고 사응에 편리하도록 만들어지는 것이므로 유효썽분 이외에 약효에 영향을 주지 않는 성분이 첨가되는 경운가 많다. 이 때 사용되는 용매들은 제피의 광택 및 건쪼시간의 단축 등을 위하여 휘발점이 낮을 용매들이 주로 사용되어진다. 본 연구는 의약품 필름코팅정제 중 잔류용매 4종(chlorofonr benzen, trichloro ethylen, 1,4-dioxane)에 대한 변형된 pirge & trap-GC 장치를 이용한 동시분석방법을 개발하였으며, 각 표준품의 RSD 값은 chloroform 3.03%, benzen 3.17%, trichloroethylen 3.69% and 1,4-dioxane 3.41%였다. 또한 시중 유통중인 의약품 50종에 대하여 잔류웅매 양을 측정하였으며, 검출되는 잔류용매는 한 건도 없었다. This study nras carried out to develope the analytical method for the mixture of chlorefonn, benzen, trichloroethylen and 1,4-dioxane simultaneously and determine the remainingorgauic solvents in coating tablets by Purge & Trap-GC. The results were as follouFs ; 1. Chloroform, benzen, trio:tloroethylen and 1,4-dioxane separated by tenax #5 trap by HP-624GC column by terrlperature programming. The peaks were separated completely at retentiontime of 6.88min for chloroform, 8.21min for benzen, 10.38miu for trichloroethylen and 11.95minfor 1,4-dioxane. 2. Standard RSD were individually chloroform 3.03%, benzen 3.17%, trichloroethylen 3.69%and 1,4-diorane 3.41%. 3. 60 samples were not detrcted chloroform, benzen, trichloroethylen and 1,4-dioxane.
