The aim of this study is to report 2 cases of acute promyelocytic leukemia who died from intracranial hemorrhage following leukapheresis and to provide proper preventive measures against hemorrhage following leukapheresis. From 1994 to 1997, a total of twenty-six patients with leukemia underwent leukapheresis to control hyperleukocytosis at Ajou University Hospital. Two patients with acute promyelocytic leukemia received all-trans retinoic acid but developed drug-induced hyperleukocytosis. Shortly after leukapheresis, they died from intracranial hemorrhage. The risk factors for fatal hemorrhage are thought to be coexisting disseminated intravascular coagulation(DIC), thrombocytopenia aggravated by leukapheresis, exacerbated coagulopathy related to mechanical trauma through leukapheresis and the excess use of citrate during leukapheresis. To reduce the risk of the bleeding associated with leukapheresis, it is necessary to replace platelet sufficiently before and after leukapheresis and to give calcium to correct coagulopathy induced by excess citrate which is used as anticoagulant as well as the correction of disseminated intravascular coagulation.

The purpose of this study was to investigate if there is any difference in the level of competitive state anxiety according to the level of motor skill before the game and to provide the players with basic data for the mental practice. The subjects of this study consist of 20 men's a middle school tennis players. The experimental group was divided into superior players group and inferior players group. And then by using a CSAI-2 questionnaire, three subfactors of competitive state anxiety, or cognitive state anxiety, somatic state anxiety and state self-confidence were measured. The method of measurement was carried out three times, or one week, one day and two hours before the game. The results of this study were as follows. First, About both cognitive state anxiety and somatic state anxiety, inferior players were significantly higher than superior players. Second, About state self-confidence, superior players were significantly higher than inferior players. Third, As the game was around, both cognitive state anxiety and somatic state anxiety which all the players including superior and inferior players had increased. But the state self-confidence of all players decreased.

A numerical study was performed to investigate characteristics of one-dimensional consolidation of soft clay. Results of consolidation tests with the remolded normally consolidation clay of having a very high initial void ratio were analyzed by using the numerical technique of finite difference method based on the finite strain consolidation theory, to evaluate consolidational characteristics of soft clay under surcharges on the top of clay. On the other hand, a numerical parametric study on soft clay consolidated due to its self-weight was also carried out to find its effect on one-dimensional consolidation. Terzaghi's conventional consolidation theory, finite strain consolidation theories with linear and non-linear interpolation of effective stress-void ratio -permeability realtion were used to analyze the test results and their results were compared to each other to figure out the difference between them.Therefore, the validity of theories was assessed.

The accurate wind speed information at the hub height of a wind turbine is very essential to the exact estimation of the wind turbine power performance testing. Several methods on the site calibration, which is a technique to estimate the wind speed at the wind turbine's hub height based on the measured wind data using a reference meteorological mast, are introduced. A site calibration result and the wind resource assessment for the Taekwanryung test site are presented using a one-month wind data from a reference meteorological mast and a temporal mast installed at the site of wind turbine. From this analysis, it turns out that the current location of the reference meteorological mast is wrongly determined, and the self-developed codes for the site calibration are working properly. Besides, an analysis on the uncertainty allocation for the wind speed correction using site calibration is performed.

김희정,김형용,권득철,윤남식 충북대학교 컴퓨터정보통신 연구소 2006 컴퓨터정보통신연구 Vol.14 No.1

여러 그룹들의 연구 결과로서 DC 방전 전산모사를 위한 여러 가지 수치해석적 방법들이 보고되어 왔다. 대부분의 방법들은 전극에 전압을 경계 조건으로 가정하고 전류를 구하는 방법인데, 때로는 전류값을 조건으로 주고 전극의 전압이 결정되는 방법이 필요한 경우도 있다. 본 연구에서는 전류값이 조건으로 주어진 경우에 전극의 전압이 결정되는 방법을 적용했으며, 1차원 전산모사를 통해 두 가지 방법에 의한 결과를 비교하였다. Various numerical simulation algorithms for simulating DC discharge were reported from many research groups. Most of reported methods uses terminal electrode voltage as a boundary condition to obtain current density. However, in some case, we need to obtain terminal voltage from boundary condition of current. In this paper, the method which obtain voltage under current condition is applied, and we compared the results of two methods through one-dimensional simulations.

목적: 우리나라에서 납에 직업적으로 노출되지 않은 일부 중년 성인들의 골중납량과 혈중납량의 수준과 상호관련성을 알아보기 위하여 40세 이상 남자 86명 여자 51명 총 137명을 대상으로 본 연구를 시도하였다. 방법: 연구변수로 골중납량인 경골납량,혈중납량을 택하였다. 경골납량은 K-shell XRF를 이용하여 각 대상 자들을 30분간 측정하였고,혈중납량은 원자흡광광도계법으로 분석하였다. 결과: 총대상자 137명의 경골납량의 평균±표준편차는 3.49±4.99 μg/g이었으며, 남자와 여자는 각각 3.90± 4.88 μg/g 및 2.80±5.14 μg/g이었으나 양군 평균의 통계적 차이는 없었다. 한편 총대상자 137명의 혈중납량의 평균±표준편차는 3.70±1.35 μg/dl이었으며,남자와 여자는 각각 3.93±1.25 μg/dl 및 3.30±1.42 μg/dl이었으나 양군 평균의 통계적 차이는 없었다. 음주,흡연 및 BMI를 통제한 후 혈중납량을 종속변수로 한 중 회귀분석에서 연령은 양의 영향을 주는 변수로 나타났다. 여자대상자만을 대상으로 한 중 회귀분석에서 교란변수를 통제한 후 연령은 경골납량에 경계수준의 양의영향을 나타내었다. 결론: 40세 이상의 우리나라 중년성인의 경골납량의 평균±표준편차는 3.49±4.99 μg/g이었으며,혈중납량의 평균±표준편차는 3.70±1.35 μg/dl이었다 혈중납량은 연령과 성과 유의한 양의 관련성이 있었으나,골중납량은 여자에서만 연령과 경계수준의 유의한 관련을 나타냈다. Objectives: In order to investigate the level and the association between bone lead and blood lead levels of non-occupationally, lead-exposed Koreans, the authors studied the lead biomarkers of 137 middle aged Koreans (86 males and 51 females) older than whose age were above 40 years. Methods: The tibia lead level was selected as the bone lead indicator of cortical bone, and the blood lead level was also measured. The tibia lead level was measured by K-shell XRF with 30-minute measurement of each subjects. The blood lead level was analyzed by AAS method. Results: The mean (SD) of the tibia lead level of the 137 study subjects was 3.49 (4.99) ,㎍/g, and tended to be higher. The mean (SD) of tibia lead level in male subjects (was 3.90 (4.88) ㎍/g) and larger than in that of female subjects (2.80 (5.14) ㎍/g), but without no statistical significance was observed. The mean (SD) of blood lead level of all total subjects was 3.70 (1.35) ,㎍/dl, and tended to be higher. The mean (SD) of blood lead level in male subjects (was 3.93 (1.25) ㎍/dl) and larger than in that of female subjects (3.30 (1.42) ㎍/dl), but without no statistical significance was observed. In multiple regression analysis of blood lead levels after adjusting for covariates, age was a significant independent variable. A weak association of age with tibia lead in female subjects was also observed in multiple regression analysis. Conclusion: The mean (SD) of tibia and blood lead levels of middle aged Koreans whose ages were over 40 years old were 3.49 (4.99) ㎍/g and 3.70 (1.35) ㎍/dl, respectively. Age and sex were positive predictors of blood lead level in multiple regression analysis after controlling for the covariates. However, in multiple regression analysis whereas age was weakly association with tibia lead level only in female subjects in multiple regression analysis.
