In order to evaluate the validity of current screening criteria of lead exposure and to provide effective information for the better health management of lead workers, author investigated the interrelationship between blood lead and blood zinc protoporphyrin(ZPP) and evaluate the validity of blood zinc protoporphyrin as the screening test and blood lead as gold standard of diagnostic test. The total of 2245 lead workers (male workers: 1982, female workers : 263) from 12 lead using industries were studied. Blood lead, ZPP, hemoglobin and hematocrit were selected as lead exposure variables. Personal information on sex, age and work duration were also checked. Blood lead was measured with flameless atomic absorption spectrometry (model: Hitachi 8100) using standard addition method. Blood ZPP was measured with portable hematoflurometer (model: Aviv 206). The results obtained were as follows: 1. The mean blood lead of all lead workers were 0.7±14.3㎍/㎗(Male: 31.0±14.4㎍/㎗, Female: 28.2±12.9㎍/㎗), whereas the mean blood ZPP of those were 68.1±47.5㎍/㎗(Male: 63.9±43.7㎍/㎗, Female: 100.1±61.0㎍/㎗). The mean value of hemoglobin and hematocrit of all lead workers were 14.5±1.5g/㎗(Male: 14.7±1.3g/㎗, Female: 12.3±1.2g/㎗) and 45.4±3.6(Male: 46.2±2.8, Female: 39.5±3.1) respectively. 2. Validity of test using blood zinc protoporphyrin as screening test for blood lead levels of 30㎍/㎗ as gold standard of diagnostic test revealed that the highest validity value for male and female lead workers were 50 and 90 ㎍/㎗ of ZPP respectively, showing 50 and 60 ㎍/㎗ of ZPP for all lead workers. While those test for blood lead levels of 40㎍/㎗ as gold standard of diagnostic test revealed that the highest validity value for male and female lead workers were 60 and 90 ㎍/㎗ of ZPP respectively, showing 60 ㎍/㎗ of ZPP for all lead workers, those test for blood lead levels of 50 and 60㎍/㎗ as gold standard of diagnostic test revealed that the highest validity value for male and female lead workers were 60 or 70 and 100 ㎍/㎗ ZPP respectively, showing 60and 70 or 80 ㎍/㎗ of ZPP for all lead workers. 3. Predictive value of test using blood zinc protoporphyrin as the screening test for different blood lead levels of 30, 40, 50 and 60㎍/㎗ as gold standard of diagnostic test revealed that positive predictive value of screening test were decreased by the increase of blood lead level regardless of csreening criteria value ZPP and negative predictive value of screening test were increased accordingly regardless of screening criteria value of ZPP. On the other hand, within same blood lead level as a gold standard positive predictive values were inceased by the increase of screening criteria value of ZPP, whereas the negative predictive value were decreased accordingly by the the increase of screening criteria value of ZPP. 4. The correlation analysis of all lead workers among study variables revealed that CPbB and natural log transformation ZPP(LZPP) were better correlated with other variables and found to be better estimate than PbB and ZPP themselves. The age was correlated with all other variables, but the work duration was not. The correlation analysis of male and female workers among study variables revealed the same results with all lead workers. 5. The slope of simple linear regression of CPbB (independent variable) with ZPP in female workers(3.223)was steeper than in male workers(2.144). That of lead workers with work duration of less than 1 year was steeper than that of lead workers whose work duration was more than 1 year. But there was no slope difference between two groups divided by their work duration of 2 years less and more. The slope of simple linear regression of CPbB lead (independent variable)with ZPP in lead workers whose blood lead were higher than 30㎍/㎗and 40㎍/㎗ were steeper than those whose blood lead were less than 30㎍/㎗ and 40㎍/㎗. 6. The slope of simple linear regression of CPbB (independent variable) with ZPP in lead industries with low mean blood lead were less steeper than those with high mean blood lead. 7. The slope of simple linear regression of CPbB (independent variable) with LZPP in female workers(0.0308was steeper than in male workers(0.0253). That of lead workers with work duration of less than 1 year was steeper than that of lead workers whose work duration was more than 1 year. But where was no slope difference between two groups divided by their work duration of 2 years less and more. While the slope of simple linear regression of CPbB lead (independent variable) with LZPP in lead workers whose blood lead were hogher than 30㎍/㎗ was not steeper than those whose blood lead were less than 30㎍/㎗, there was no slope difference between two groups whose blood lead were less than 40㎍/㎗ and more than 40㎍/㎗. 8. The slope of simple linear regression of CPbB (independent variable) with LZPP in lead industries with low mean blood lead were less steeper than those with high mean blood lead, but the difference was not significant then that of CPbB and ZPP. With above results, it is recommended that the screening criteria value of ZPP should be down to 60-70㎍/㎗ from 100㎍/㎗ for male lead workers and screening criteria of ZPP for female lead workers was all right with current value of 100㎍/㎗. So it is recommended to make different screening criteria of ZPP for male and female workers like the hemoglobin and hematocrit screening criteria. It is also preferable to use CPbB and LZPP rather than uncorrected PbB and ZPP in the evaluation of lead exposure for lead workers.

Subacute combined degeneration is a metabolic disorder of the spinal cord caused by vitamin B12 deficiency. A 72-year old man was admitted with weakness and tingling sensation of the bosh upper extremities. 9 years ago, he was diagnosed as having stomach cancer. So total gastrectomy with splenectomy was done at that time. The complete blood cell counts and morphology revealed megaloblastic anemia. Nerve conduction velocity study(NCV), electoromyography(EMG) and somatosensory evoked potentials(SEP) showed diffuse sensorimotor peripheral neuropathy. Magnetic resonance imaging(MRI) showed an increased T2-weighted signal, mild decreased T1-weighted signal, and slight contrast enhancement of the posterior columns of the cord in the cervical and upper thoracic spinal region. He was treated with vitamin B12 supplements and improved gradually. If abnormal sensation and muscle weakness was developed after gastrointestinal surgery, subacute combined degeneration should be considered in the differential diagnosis. We describe MRI findings of a typical case of subacute combined degeneration, which was induced by total gastrectomy.

In this paper, a fuzzy logic controller is designed for speed control of a hydraulic inverter elevator. Mathematical modeling of an elevator actuated with hydraulic system is presented and the friction characteristics of a cylinder is examined, which may cause the abrupt increase of the acceleration in the zero-crossing speed region. Simulation results show that the proposed fuzzy logic speed controller yields a better control performance than conventional PID controller.

연구목적 : 일반 청소년의 문제행동(내재화 문제, 외현화 문제)을 평가하고, 그들을 정상 집단과 문제행동 집단으로 나누어 집단간에 부모 각각의 양육행동이 어떠한 차이를 보이는지 알아보고자 한다. 방 법 : 서울 소재의 일반 고등학교 학생 792명을 대상으로 부모 양육행동 척도와 K-YSR을 실시하여 청소년이 지각하는 부모의 양육행동과 청소년의 문제행동을 평가하였다. 부모의 양육행동과 청소년의 문제행동과의 상관관계를 분석하였다. 학생들이 보고한 각 문제행동을 상/하위 25% tile을 기준으로 정상 집단과 문제행동 집단으로 나누어 부모의 양육행도의 차이를 분석하였다. 결 과 : 다음과 같다. 1) 부모의 애정, 합리적 설명, 감독의 긍정적인 양육행동은 대부분의 청소년 문제행동들과 유의한 부적 상관을 보였다. 반면에 학대, 과잉간섭, 과잉기대, 방임, 비일관성이 부정적인 양육행동은 문제행동들과 유의한 정적 상관이 있었다. 2)내재화 문제를 보이는 청소년들은 정상 집단에 비해 부모로부터 학대, 과잉간섭, 과잉기대, 방임, 비일관성의 양육행동을 유의하게 더 많이 받았고, 반면에 애정을 유의하게 더 적게 받았다고 지각하고 있었다. 외현화문제를 보이는 청소년들은 정상집단의 청소년들에 비해 부모로부터 학대, 과잉간섭, 과잉기대, 방임, 비일관성의 양육행동을 유의하게 더 많이 받았고, 반면에 감독을 유의하게 더 적게 받았다고 지각하고 있었다. 3) 내재화 및 외현화 문제를 모두 보이는 집단이 내재화 문제만 보이는 집단과 외현화 문제만 보이는 집단에 비해서 양쪽 부모로부터 유의하게 더 많은 과잉간섭을 받을 것으로 지각하고 있었다. 또한, 내재화-외현화 집단과 내재화 집단은 외현화 집단에 비해서 어머니로부터 유의하게 더 적은 애정과 더 많은 방임을 받고 있고, 아버지로부터 유의하게 더 많은 학대를 받은 것으로 지각하고 있었다. 결 론 : 이상의 결과로 미루어 볼 때, 청소녕이 지각한 부모의 학대, 과잉간섭, 과잉기대, 방임, 비일관성의 양육행동은 청소년의 내재화 및 외현화 문제 모두와 유의한 연관이 있고, 반면에 부모의 애정, 감독, 합리적 설명의 양육행동은 다양한 청소년기 문제행동을 줄일 수 있음을 시사하고 있다. Objectives : The purpose of this study is to evaluate the problem behaviors of adolescents and to discriminate between parenting behaviors of problem behavior groups and those of non-problem behavior group. Methods : The subjects of this study were 792 high school students in Seoul. We administered 'parenting behavior Inventory' and Korean version of Youth Self-Report(K-YSR) to the subjects in order to evaluate the parenting behaviors perceived by adolescents and the problem behaviors of adolescents. We analzed the relationship between parenting behaviors and problem behaviors. We classified the subjects into problem behavior groups(internalizing group, externalizing group, internalizing-externalizing group) and a non-problem behavior(normal) group. We studied the differences of parenting behaviors among the groups. Results : The results are as follows. 1) There were significant negative correlations between the positive parenting behaviors such as affection, reasoning, and monitoring and the problem behaviors of adolescents. By contrast, there were significant positive correlations between the negative parenting behaviors such as physical abuse, intrusiveness, over-expectation, neglect, and inconsistency and the problem behaviors of adolescents. 2) Adolescents of the internalizing group perceived significantly more parental abuse, intrusiveness, over-expectation, neglect, and inconsistency than those of normal group. Meanwhile, they perceived significantly less affection than normal adolescents. Adolescents of the externalizing group also perceived significantly more parental abuse, intrusiveness, over-expectation, neglect, and inconsistency than those of normal group. Also, they perceived significantly less monitoring than normal adolescents. 3) Adolescents of the internalizing-externalizing group perceived significantly more intrusiveness from both parents than those of either the internalizing or the externalizing groups. Adolescents of the internalizing-externalizing group perceived significantly less affection and more neglect from their mothers than those of the internalizing of the externalizing groups. In addition, adolescents of the internalizing-externalizing group perceived significantly more physical abuse from their fathers than those of the internalizing or the externalizing groups. Conclusion : Parenting behaviors such as abuse, intrusiveness, over-expectation, neglect, and inconsistency are associated with both internalizing and externalizing problems. In contrast, our results suggest that parenting behaviors such as affection, monitoring, and reasoning might decrease the various problem behaviors of adolescents.
