Recently science curriculum in middle school was reformed the fifth and the science textbook of middle school is five species. In order to prompte educational effect, this study compared and analyzed five kinds of new science textbook with an old science textbook of the second year in middle school The results of this study can be summarized as follows. 1) Reformed five kinds of science textbook have various contents by participating 50 authors 2) Reformed science textbook increased 10 pages more than old science textbook of middle school in quantity. 3) It was found out that the numbers of the "Study and Observation" and "Exercises and Questions" in new science textbooks increased. 4) The numbers of Pictures were unchanged and the numbers of Tables. Experiments, Exercises and Composite Questions were decreased. 5) The 38∼42% was appeared the ratio of Experiments, Tables, Pictures, and Goethic type Terms in more than three kinds of science textbooks. 6) New science textbooks were reflected 61∼75% of an old science textbooks in Pictures, Goethic type Terms, Tables, and Experiments. As these results Terms and Contents reprented by Goethic type in science textbook should be selected carefully in order to prompte educational effect. The selection of Exercises, Composite Questions, Experiments and Observations should be allocated equally to each unit and behavior area. And this study suggests that there should be introduced experiments of an environment pollusion and its influence into a science textbook.

This survey is to study the corresponding degree of water pollution of the Kum river areas, covering the eight places of main stream of the river from the Daechung dam to Kangkyung county, and two trivutary streams of Kap stream, and Miho stream. Besides, the heavy metal content of the fishes, shellfish, moss, and soil in the main stream of Kum river is investigated, whose results are as follows: 1. The water quality The water quality of the area from the Daechung dam to the Sintanjin county is first grade for the standard of drinking water in terms of BOD, COD values, that of both Kap stream and Miho stream is third or fourth grade respectively, and the other areas are turned out to be second grade. The water of the Daechung dam to the Sintanjin has little NO₂-N and ??, which can be said to be possible for the drinking water. The quantity of ?? and ?? in the water of all the areas is below the standard for the available drinking water, but, that of Kap stream and Miho stream is about two or three times higher than other areas. 2. Heavy metal The content of Cd, Cu, Mn, and Zn are shown to be comparatively less than that of Co, Fe, Ni, and Pb. And the content of Cu, Mn, Zn are less than the possible standard value for the drinking water. The relationship of the heavy metal content of the fish and shellfish were in order of Co>Zn>Cu>Cd, for the moss, Zn>Pb>Co>Cu>Cd, and for the soil, Zn>Pb>Cu>Co>Cd. The most of collecting samples in the Kumnam area have lots of heavy metals, and Pb is well contained in shells than fishes. When summarize the above result, the water in the Daechung dam and Sintanjin area is comparatively favorable for the drinking water, and the water quality below the Kumnam areas appears to be wores because of influx of Kap stream and Miho stream. In short, the necessary counter measure is to be required for the good preservation of water of fine quality in Kum River.

오제직,홍춘표,김화영 공주대학교 사범대학 과학교육연구소 1994 과학교육연구 Vol.25 No.1

The purpose of this research is to compare and to analyze eight different science textbooks Ⅱ (the last volume) that are presently in use at the high school. The items that were compared and analrzed are as follows: The construction of each textbook in quantity. The construction of experimentation contents. The construction of contents in textbooks. This study will provide the basic data that is needed to effectively accomplish aims of science education and to enable a guidance teacher to reconstruct the textbook properly to the real condition exiting in each school. The findings of the research are as follows: 1. There is little difference in quantity of materials. But there is difference in quantity of each unit. 2. The number of Gothic-type terms used in each textbook is not unified. The sort of Gothic-type terms used in each textbook is also varied. 3. Photographs and pictures are presented in black and white. They are used for only explaining. 4. Material and method used in experimentation are showed in many ways. But some units are given too much importance. 5. Contents are consisted variously according to authors under the basic frame of education curriculum.

Developmental anomalies of the aortic arch, commonly known as vascular rings, are relatively rare congenital vascular anomalies which can compress the trachea and esophagus. One routine chest film of a patient who was checked and hepatoma-diagnosed in Internal Medicine, Chosun University Hospital left the room for doubt of mediastinal mass. But no subjective symptoms for the mass was told by the patient. This is to report our experience of a patient having right side aortic arch with aberrant left subclavian artery, as proved by diagnosis, but none of congenital heart disease. This right side aortic arch with aberrant left subclavian artery is the most frequent type among right aortic arch, the anomaly of which is usually detected from the incidental suspicion for mediastinal mass at routine chest film; because no symptoms are accompanied therewith.

Inspite of possible effects for emesis following chemotherapy including cisplatin, nausea and vomiting are the most unpleasant side effects of cancer chemotherapy. None of the currently available antiemetic agents is entirely effective preventing emesis. Ondansetron, a 5-HT(5-hydroxytryptamine)_(3) receptor antagonist, has been shown to be effective antiemetic agent in the control of cisplatin induced emesis. Twenty solid tumor patients who are scheduled to receive cisplatin containing combination chemotherapy participated in a prospectively randomized study to compare the antiemetic efficacy and safety of ondansetron and metoclopramide. Ondansetron was given in dose of 8mg intravenous 30min before cisplatin and then 4hours and 8hours after cisplatin on day 1, and Ⅰ.Ⅴ. every 8hours from day 2 to 5. In the metoclopramide group, metoclopramide was given in dose of 2 ㎎/㎏ intravenous every 8hours from day 1 to 5. The control of emesis was graded in the following way : complete response, no vomiting : major response, 1-2 emetic episodes : minor response, 3-5 emetic episodes : failure, above 5 emetic episodes. Complete or major response of emesis was achieved 10 of 12(83.2%) patients receiving ondansetron and in 5 of 8(62.5%) patients receiving metoclopramide, but effectiveness was not significantly different. Ondansetron was at least as effective as metoclopramide therapy in controlling cisplatin induced emesis. Side effects in ondansetron was less than in Metoclopramide.
