Currently the evaluation of high school science and mathematics learning has been too much knowledge-centered without concerning the inquiring ability or scientific attitude. This study, therefore, was made for the purpose of establishing of evaluation model for high school science (biology and earth science) and mathematics learning and its evaluation items. In this paper, the research was done about three fields, biology, earth science and mathematics. 1. For the biology, the evaluation methods of inquiry learning were studied with the foreign references, and proper evaluation items were suggested. 2. For the earth science, after analizing 5 kinds of earth science textbook of current using in high school, essential 19 items were selected. 5 of them were tested in test group and control group, then, the results were analized. 3. For the mathematice, the teaching elements of「Set」and「Flow chart」in mathematics (Ⅰ) were selected and structured. Detailed teaching objects were established and evaluation items were introduced.

In order to evaluate the effects of trichloroethylene(TCE) on the central and autonomic nervous system, the brain stem auditory evoked potentials(BAEPs) and the electrocardiographic R-R interval variability(CVRR) were measured in three groups of workers(11) working in TCE degreasing process, workers(4) exposed to lead and two groups of workers(12) not exposed to any kinds of neurotoxicants. Two components of the CVRR reflecting parasympathetic activity(C-CVRSA) and sympathetic and parasympathetic activities(C-CVMWSA) were examined. The TCE workers were exposed to TCE at the level of less than 1 hour per week while the degreasing material was changed. There were no differences in the latencies of BAEPs and CVRR and the components of the CVRR between control and TCE and lead groups. However, two lead workers had the blood lead level of less than 60 g/dl recommended as present biological guideline by the Ministry of Labor, showed the delayed latencies of V5 and I-V in BAEP. This results suggested that intermittent TCE exposure didn't affect the auditory nervous pathway and the autonomic nervous system, however, lead exposure might affect the central nervous system at the level of less than 60 g/dl in blood lead.

지구과학의 개념형성학습에 관하여 : 변화에 대한 개념을 중심으로 Especially Concerning to Concepts about Changing Phenomena

姜用熙,林成圭 경북대학교 과학교육연구소 1989 科學敎育硏究誌 Vol.13 No.-

By analyzing Earth Science textbooks currently used in high schools. we tried to establish a basic conceptual system concerning to changing phenomena based on the ESCP's structuralizing scheme. Investigating facts about time and change, we have found 21 basic concepts which should be understood through concept-forming teaching and learning. By classifying the basic concepts to fit the four principles suggested by NSTA as a scientific basic-system. we also tried to generalize the selected concepts. We made test problems in order to test high school students' understanding about earth science concepts especially concerning the changing phenomena in the field of astronomy. Using questionnaire method, we applied the test problems to 160 high school students in Taegu and Kyungpook areas. The results were as follows : the mean score of concept-learned group was 56.0 and that of unlearned group was 48.5. This means that the learned-group had been improved by concept-forming teaching.

This study was investigated the Family APGAR. Scores which was introduced in 1978 as a utilitarian screening instrument for family function by Dr. Smilkstein. The Family APGAR Index Questionnaire consisted of five items : adaptation, partnership, growth, affection and resolve. The Index Score is ranged from 0 to 10 and is divided into three groups; severly dysfunctional 0-3, moderately dysfunctional 4-6, and highly functional 7-10, for evaluating the family function. For this study, 466 high school students were chosen and divided into two groups; Three-choice response format group (Group I) and five-choice response format group (Group Ⅱ ). For comparison, 200 reformatory students whose age were similar to the Group I were selected. The retest was carried out after an interval of two weeks to Group I . The results of this study are as follows. 1. In Group I, the mean Family APGAR Score is 5.45±2.17. The range of inter-item correlations are 0.18-0.34 and item to total correlations are 0.55-0.63. 2. In Group I , 31.4;% belongs to highly functional families, 48.3% moderately dysfunctional families and 20.3% severely dysfunctional families by Smilksteins' classification. 3. The three-choice response format results in good scale qualities and is simpler although fivechoice response format yields some improvement in psychometric qualities of the instrument. 4. The difference in Family APGAR Scores between high school students group and reformatory students group is statistically significant (P<0.01). 5. The coefficiency of test-retest reliability after and interval of two weeks is 0. 3225, which is statistically significant (P<0.001). As a result, this study suggested the possibility that the Family APGAR Scores could be applied to the Korean for evaluating family function.

88 workers exposed to cadmium were examined at the 12 factories using or producing cadmium in order to know the present state of cadmium exposure and renal dysfunction in 1992. Cadmium in blood and in urine were measured and compared by the 3 exposure level of cadmium in air. Cadmium in blood of low, moderate and high exposure group were 2.5, 3.8 and 7.6 ㎍/L, respectively. Cadmium in urine were 1.8(1.3), 3.8(2.6) and 7.9 ㎍/L(6.1 ㎍/g creatinine), respectively. However, there was no relationship between urinary cadmium and β₂-microglobulin. Cumulative exposure estimate(CEE) was calculated by multiplying the mean ambient cadmium level of the factory and working duration. CEE has a high correlation with cadmium in blood and urine, but no relation to β₂-microglobulin. Because working durations were relatively shorter than European workers', the highest CEE was just 300 ㎍·year/m³, which was not enough to induce renal tubular dysfunction. This study, however, suggested the possibility that renal tubular dysfunction caused by cadmium could be happened in Korea in the near future.

To investigete the obstacles of developing physics education in secondary schools and the countermeasure in present situtation, I distributed subject - description style answer sheets to middle & high school teachers in Cheju, which consist of 28 detail subjects under the big 8 themes. The recovery rate is 75%, and now I'm describing the result. According to the themes, total frequency is like this : Derection of Physics Leaming(412), Administration of Physics Facilities and Other Elements(298), Administration of Physics Education(268), Contents of Text( 183), Events of Science(163), Guiding of Students(l23), Grade and Evaluation of Students(101), 6th Education Cumculum(86). It suggests as the improvement that experiment training for teachers be reinforced, programs about new physicse teaching menthod be introduced, teachers try to motivate the students in class, teaching material for students?advanced learning be developed, usage of teaching material be presented, qualified experiment assistant be arranged and no less than two laboratories be provided by school unit and hours of teaching on physics teacher lessen. Besides, science events need to be held for every student by school unit, which should be eximined about when and how they would be he held.

우리나라 직업성 암의 역사와 현황

강성규 東國大學校醫學硏究所 2002 東國醫學 Vol.9 No.1

우리나라에서 암으로 인한 사망이 점차 증가 추세에 있다. 1999년 전체 사망자 중 22.3%(246,539명 중 55,005명)가 암으로 인해 사망하였는데 직업성 폭로가 몇 가지 암의 발생에 기여한다고 알려져 있다. 모든 암의 4% 혹은 폐암의 10%가 직업성 폭로에 의한다고 가정한다면 연간 2,000명이 넘는 암환자가 발생할 수 있지만, 현재까지 기대한만큼 직업성 암의 보고느 많지 않다. 공식적으로 우리나라에서 직업성 암의 발생을 처음으로 보고한 것은 1992년 석면포 공 장에서 근무한 근로자에서 석면에 폭로되어 발생한 중피종의 경우였다. 이어서 많은 직업성 암의 보고가 있었는데, 석면, 크롬, 배출가스, 코크스로배출물, 실리카 등에 의해 발생하는 폐암, 벤젠이나 다른 유기용제에 폭로되어 발생하는 백혈병, 벤조딘솔트에 폭로되어 발생하는 방광암 등 다양하였다. 1992년 부터 11개의 발암물질에 폭로되었던 근로자에서 직업성 암을 조기에 인지하기 위해 퇴직후 건강검진이 시작되었다. 그렇지만 지금까지 퇴직후 건강검진을 통해 밝혀진 직업성암은 아직 없다. 1992년부터 한국근로복지공단은 산업안전보건연구원에 직업성 암에 대한 105건의 심의를 요청하였고, 그중 29건이 직업성 암으로 인정되었다. 이중에는 13건의 폐암, 6건의 혈액암, 6건의 중피종이 있었다. 결론적으로 직업성 암은 잠복기가 길고 일잠적으로 퇴직후에 발견하는 경우가 많기 때문에 직업성 암을 인지하기 위해서는 특별한 관심이 필요하다. The proportion of cancer as a cause of death in Korean has been continuously incresing. In 1999, 22.3%(55,005 of 246,539) of death were caused by cancer. Occupational exposure would have contributed to the development of some cancers. It would have accounted for more than 2,000 cancers in a year if 4% of all cancer or 10% of lung cancer was regarded as arising from the work environment. However, occupational cancer has not been reported as much as expected. The first case of occupational cancer reported officially was mesothelioma caused by asbestos exposure at an asbestos textile industry in 1992. Following the report, many cause of occupational cancers have been reported such as lung cancer due to exposure to asbestos, chromium, exhaust gases, coke oven emissions, and silica, as well as leukemia due to exposure to benzene or other solvent and bladder cancer arising from exposure to benzidine salts. The Health Examination for retirees has been conducted since 1992 in order to detect occupational cancer early in workers who have been exposed to 11 carcinogenic substances. However, to date no occupational cancer has been detected through the Retirees' Health Examination. To date the Korea Labor Welfare Corporation (KLWC) has referred 105 claims for occupational cancer to the Korea Occupational Safety and Health Agency (KOSHA) from 1992. Twenty-nine cases were accepted, including 13 cases of lung cancer, six cases of hematopoietic cancer and six cases of mesothelioma. In conclusion, special attention is required to detect occupational cancer due to their long latency period and the fact they are usually found after retirement.

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.
