Bronchial Asthma could be developed by occupational origin. 4-16% of bronchial asthmas are known to be related to occupational exposure. However, occupational asthma has not been reported from the periodic occupational health examination, but reported through case report from clinicians. The authors analysed hospital records to find out work-related bronchial asthma and their occupational characteristics at a university hospital in Inchon. All records which were confirmed as bronchial asthma in adult by an allegist from June, 1996 to May, 1998 were selected. Through record reviewing, any suspected work related asthma was selected and the inteview was done by phone or at the out-patient clinic. The possible cases were confirmed by additional tests including specific bronchial provocation test. Sixteen(3.9%) out of 411 bronchial asthma were confirmed as work-related asthma. Eight cases out of 16 worked at furniture industry, three worked at dye manufacturing and two worked at musical instrument manufacturing industry. Others worked at farm and machinary industry. The confirmed asthmogen were toluene diisocyante(8), reactive dye(3), and grain dust(1). None of the cases was detected as work-related asthma in the periodic health examination. Twelve out of sixteen occupational asthma patients discontinued their work. The results suggested that many patients with occupational asthma were not reported and the periodic health examination was not an effective system for detecting the workrelated asthma. Thus setting up the surveillance system involving allergist or pulmonologist would be important to detect and prevent occupational asthma.

솔-젤공정에 의한 한외알루미나 여과막의 기공보정에 관한 연구

채만병,조원준,정은정,이진휘,서동호 서울産業大學校 1996 논문집 Vol.44 No.1

서로 다른 입자 크기의 3층 구조를 갖는 튜브 형태의 한외 알루미나 분리막은, 일반적으로 제조공정중 분리층에 결손부분이 발생하기 때문에 낮은 선택도 및 제거율을 보인다. 이와같은 결손부분을 보정하기위하여 습도조절에 의한 선택적 적심(alternative wetting by controlled humidity)을 한 수 colloidal silical 솔을 적용하여 처리하고 특성을 평가 하였다. Sealing처리한 분리막에 대한 누수여부를 평가하기 위하여 3가지의 염료로 조사하였고, 보정전분리막과 보정후분리막에 대한 SEM, 액체으 투고도, 선택도 및 P.E.G./물 혼합물의 제거율을 측정하였다. P.E.G 2000, 12000 및 35000에 대한 제거율은 각각 약 0.6, 18 및 17% 향상된 결과를 보였으나 colloidal silica 솔의 deposition에 기인하여 투과율의 감소는 77%였다. 이상의 결과에서 보면 습도조절에 의한 선택적 적심법은 비록 deposition에 의한 문제점을 내포하고 있으나 액체분리를 위한 알루미나 한외여과막의 보정에 효과적인 방법이다. The 3-layer type alumina membrane consisting of different pore size shows the decreased selectivity and rejection because of cracks in the separation layer generally occurred during the manufacturing process. To modify these cracks, the colloidal sol is applied by sol-gel process after treating by alternative wetting method using controlled humidity(Alternative Wetting Method by controlled humidity) and evaluated the characteristics. For the evaluation of the leakage for the sealed membrane, the sealed membranes were tested by 3 kinds of dyes. For the comparing of native and modified membranes, the modified membranes for the cracks treated by Alternative Wetting Method by controlled humidity were also tested by SEM, permeability by liquid equipment, selectivity and rejection of the P.E.G./water mixtures. The results showed that the rejections were increased ca. 0.6, 18 and 17 % for the P.E.G. polyethyleneglycol 2000, 12000 and 35000 individually. The permeabilities are decreased, however, 77% for the pure water caused by deposition of colloidal silica sol after caulking. In conclusion, the Alternative Wetting Method by humidity control had the effect for the modification of ultrafiltration alumina membrane for separation of liquids and gases, though having problem of deposition.

과학과 수행평가를 위한 평가체계의 개발 Ⅱ : 과학지식의 적용력 평가체계의 실제 Evaluation System of Applying Scientific Knowledge

김은진,임채성 부산교육대학교 과학교육연구소 2003 科學敎育硏究 Vol.28 No.-

In this study, we developed a evaluation system for performance assessment on applying science knowledge. It was based on theoretical background that we had studied previously. According to previous study, applying scientific knowledge is considered as science problem solving. So, we also developed a elementary science performance assessment tool based on science problem solving processes. the tool consist of a task, a response format and a scoring system, as other performance assessments with high quality the scoring system developed to assess students' responses contained in the response formats showed significant degrees of agreement among a science education expert, a in-service teacher an pre-service teachers. Therefore, by using the scoring system which based on assessment criteria, the whole processes of student learning could be assessed objectively.

In this study, the frequencies and types of questions about LIFE areas of the Science Curriculum of elementary school students were investigated through in-depth interviews with twelve 4th and 5th graders. The results of the research can be summarized as follows: (1) In conjectural question, the proportions of 'object exploration question' and 'object verification question' were high in all of the 4th graders and the students of low achievement level. (2) The numbers of causal questions generated by the 4th graders were much higher than those of the 5th graders. (3) The frequencies of the predictive, methodological, applicative questions were very low both in 4th and 5th grade students. (4) The numbers of conjectural questions were more in all students except the low achievement level of 4th graders at not-yet-taken contents than at already-taken ones. (5) The numbers of causal questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (6) The numbers of the predictive, methodological, applicative questions of the 4th graders were more at not-yet-taken contents than at already-taken ones, whereas opposite trend in the 5th graders. (7) The numbers of students' curriculum-related questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (8) As ways for solving or seeking answers about questions, the 4th graders suggested methods of consulting experts or teachers (23.9%), internet searching (21.6%), and books or science-related encyclopedia (20.3%), while the 5th graders suggested the internet searching (36.5%), consulting experts or teachers (24.8%), and books or science-related encyclopedia (17.7%). Based an these results, we suggest several ways for improving the question-posing abilities of the students and adequate use of students' questions in the process of science teaching learning.

김은진,임채성 한국초등과학교육학회 2003 초등과학교육 Vol.22 No.2

The purpose of this study was to investigate about current status of science field study in elementary schools. A total of 72 elementary teachers in Busan and Gyungnam districts were involved and the data from questionnaire was gathered. The questionnaire was comprised two parts: items on general level include the epistemological aspect and actual condition and items on concrete level according to chapters of elementary school science curriculum. The major findings are as follows: 1. May teachers cognize the requirement of science field study in 7th Korean elementary school science curriculum is larger than 6th one. But they respond the actual number of science field study in 7th curriculum is nearly equal to 6th. 2. In analysis to grades, the actual number of field study decrease as grade is high. 3. In the science content aspects, the requirement of field study is the largest on biology domain and earth science domain. 4. Many teachers have pointed out "the difficulty of administration for field study" and "inappropriated surrounding their school" as the problems of science field study in elementary school.

This study was carried out to survey origins of native plants and introduced flowers. Naming of native plants was divided into two types : one type is based on the internal properties of plants(shape, color, length, thickness, size) and the other type on such properties as person, animal, object, place and time which are compared to shapes and properties of plants. Names of native plants originate from shape > color > length > thickness > size > width > number, and also from characteristics > state > inhaitation place and place of origin > flowering and fruiting season > function and use. Prefixes were added in order to describe shapes and properties of plants in detail. About 50% of the names of the introduced flowers, originates from their shapes, about 15% from persons' names and about 13% from mythologies and legends. This shows that countries have different ways naming flowers from other countries and that survey of origins of flower names helps understand the characteristics of the flowers.
