Twenty-four factories registered at the Ministry of Labor as factories using or producing cadmium in 1991 were investigated to know the present state of occupational exposure to cadmium in 1992. Nine factories among 24 stopped using or changed to other substances and 1 factory didn't produce any more, but delivered it to other factories through imports. Therefore, only 14 factories were producing or using cadmium. But, alloying materials were supplied to about 20 and more factories, however, they couldn't be investigated because of limited information. Three factories had less than 50 workers were 3,6 had 50-300 and 5 had more than 300. About 167 workers were exposed to cadmium. According to the classification by process, there were 4 alloy processes, 2 refinary, 2 elctroplating, 2 dry cell making, 1 industrial battery making, 1 duplicator drum making, 1 recycling of battery and 1 copper refinary. 8 factories used metal cadmium, 3 cadmium oxide, 2 cadmium sulfide, and 1 cadmium hyroxide. One factory was importing cadmium stearates only and supplying them to the PVC making factories. The amount of metal cadmium producing in 2 refinary factories was about 50-65 ton per month. The other cadmium compounds were imported. According to exposure level of cadmium air of the 10 factories examined, each factory could be divided into high, moderate and low exposure groups. 1 battery recycling factory and 3 alloy factories were in the high exposure group and their mean air concentrations were 0.06679, 0.05481, 0.02492, and 0.003㎎/㎥, respectively. Refinary and industrial battery making factories were in the middle exposure group and their mean air concentrations were 0.00773 and 0.00613 ㎎/㎥, respectively. Finally, low exposure group were copper smelting, dry cell case making, duplicator drum making and electroplating factory and their mean air concentrations were 0.00096, 0.00071, 0.00057 and 0.00054 ㎎/㎥ respectively.

김재표,이석희,문성배 부산대학교 사범대학 과학교육연구소 2000 科學敎育硏究報 Vol.27 No.-

Science Education has been mainly concerned with teaching scientific knowledge and method at class. And its focus on the conveyance of scientific knowledge itself resulted in the limited understanding of science to the students. So the Science-Society(STS) has put more emphasis on the understanding of science, technology, and society rather than the science knowledge only. The goal of STS education is to develop students to understand how science, technology and society interrelate and to use the knowledge they learned in everyday decision making. The purpose of this study was to evaluate the effect of the STS Model in chemistry chapter of Third Grade students' Science textbook in Middle School. 1. In the scholastic achievement, the experimental class showed higher scores by 12.8% points in the rate of correction especially in the problems which were demanding scientific inquiries. This indicated problem-solving through discussion could help the students have correct understanding of science. 2. In pretest, there were no statistically significant differences between 2 classes in the improvement of scientific inquiry abilities. However, in posttest, the experimental class showed higher scores by 2.0% points. 3. In the analysis of science-related attitude, students didn't take much interest in the science subject itself. The didn't prefer the jobs which are related with the science, either. But the STS teaching model received so much recognition that 63.8% of the showed their favor of the teaching method which required discussion in relation between science and society in their science class. And 80.7% of them believed that it would be more interesting when the contents of science textbooks would be changed about those of their authentic lives. 4. About the STS teaching method, 85.0% of the students become more interested n the group discussion and presentation. However, 55.0% of them complained about the lack of little time in preparing material and teachers' enough explanation.

연구목적 : 본 연구는 국제적인 정신장애 진단도구인 Composite International Diagnostic Interview(CIDI)를 한국의 사회문화적 상황에 적합하게 번역하고 신뢰도 및 타당도를 평가하여 한국어판으로 개발하기 위한 것이다. 방 법 : CIDI는 정신장애를 평가하고 진단할 수 있는 포괄적이고, 완전히 표준화된 진단도구로 훈련받은 일반인들이 적용할 수 있기 때문에 대규모 역학조사에 적합하다. 세계보건기구에서 제공하는 CIDI 번역 지침에 따라 한국어판 CIDI(K-CIDI)를 제작하였다. 영어권과 한국의 언어 및 사회문화적 차이를 고려하여 번역 및 개정을 하였고 역번역을 통하여 원본의 의미와 일치하는지를 확인하였다. 임상환자를 135명과 일반인 5명을 대상으로 신뢰도와 타당도 검사를 실시하였다. 두 명의 평가자가 K-CIDI를 이용하여 동일한 대상자를 동시에 면담하고 일주일 뒤에 재검사를 실시하였다. K-CIDI로 검사를 받은 대상자들을 정신과 전공의와 임상심리사가 한국어판 Structured Clinical Interview for DSM-Ⅳ를 이용하여 진단을 내렸다. 두 가지 진단의 일치도에 대한 kappa값을 산출하였다. 결 과 : CIDI의 번역에서 한국어 표현이 복잡하고 긴 문항은 두 개의 문장으로 분리하였고, 성과 관련된 표현과 의료체계 및 의료추구행태에서 사회문화적 차이를 반영하였다. 공포장애의 대상과 알코올 및 물질의 종류도 한국의 실정에 맞게 조정하였다. 현장 검사와 역번역 과정에서 K-CIDI가 적절하게 제작된 것으로 평가되었다. K-CIDI의 평가자간 신뢰도 검사는 140명에 대하여 이루어졌고 kappa값은 진단에 따라 0.86∼1.00범위였다. 검사/재검사 신뢰도 검사는 47명에 대해 이루어졌고 kappa값은 진단에 따라 0.42∼0.89였다. K-CIDI의 타당도 검사는 50명에 대해 이루어졌고 kappa값이 진단에 따라 0.50∼1.00의 범위였다. 결 론 : K-CIDI는 한국의 사회 문화적 배경에 적합하게 제작되었고 신뢰도 및 타당도 검사에서 역학연구에 적절한 진단도구로 평가되었다. Objectives : This study aims to develop a Korean version of the Composite International Diagnostic Interview(K-CIDI). Methods : The Composite International Diagnostic Interview(CIDI) is a comprehensive, fully standardized interview that can be used to assess psychiatric disorders and provide diagnoses. The K-CIDI was developed according to the guidelines provided by the WHO. The reliability and validity of the K-CIDI was evaluated by examining 135 psychiatric patients and five community residents. Subjects were jointly interviewed twice with a one-week interval. A psychiatric resident and clinical psychologist jointly determined clinical diagnoses using the Structured Clinical Interview for DSM-Ⅳ. Results : Notable modifications were done on sex-related expression, health system and help seeking behavior, subjects for phobic disorder, and kinds of alcohol and substance. Long and complex questions were divided into two or more questions. Field test and back-translation of the K-CIDI confirmed the appropriateness of the translation of the CIDI. The inter-rater reliability, test/retest reliability, and validity of the K-CIDI indicated kappa values ranging from 0.86-1.00, 0.42-0.89, and 0.50-1.00, respectively. Conclusion : The K-CIDI was deemed to be appropriate for the sociocultural background of Koreans. The reliability and validity of the K-CIDI were judged to be exceptionally acceptable.

This study analyzed the influence of paste fluidity and vibration time for fundamental properties of porous concrete. Results of this study were shown as follows: 1) Even if target void ratio is same, void ratio and compressive strength of porous concrete is different according to w/c, paste flow and vibration time. So, In case of target void ratio, we must consider the influence of w/c, past flow and vibration time. 2) Though w/c and vibration time is same, as paste flow increase, all void ratio, continuous void ratio, and compressive strength decrease and difference between upper and lower void ratio increase. 3) Though w/c and paste flow is same, as vibration time increase, all void ratio and continuous void ratio decrease and difference between upper and lower void ratio increase. Also, compressive strength increase by 10 seconds and decease after 10 seconds. 4) As types of superplasticizer is different, all void ratio, continuous void ratio, and compressive strength is different. So, we must give consideration to paste fluidity and vibration time in order that increase of strength of porous concrete and distribution of uniform void.

연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.
