The purpose of this study is to manifest the effect of STAD cooperative learning which has not yet been explained in cooperative learning of an elementary school, on the academic achievement in science and science related attitudes. Therefore, in order to achieve that purpose, I established the following issues of study. First: What effect does STAD cooperative learning have on the elementary school students' academic achievement in science? Second: What effect does STAD cooperative learning have on the elementary school students' science related attitudes? The results of the study are as follows. First, while it was proven that the effect of STAD cooperative learning on academic achievement in science had no significant difference in pre·post achievement levels for both the experimental group and the control group, the experimental group showed larger changes in the mean value than control group; it can be inferred that classes to which cooperative learning is applied is more effective than traditional science classes. Second, in regard with the effect of STAD cooperative learnign on science related attitudes, while there was a significant difference between the experimental group and control group in pre examination, there was no significant difference, which means STAD cooperative learning does have effect on science related attitudes. In conclusion, the results of this study manifest that STAD cooperative learning is effective for science related attitudes in elementary school science classes, and assume that it can be effective for academic achievement.

The mass treatment trial of pyrantel pamoate on Ascaris lumbricoides and Ancylostoma duodenale infections was carried out to school-children and inhabitants in rural areas in the central part of Korea. Pyrantel pamoate ("Combantrin") tablet (123 mg base) was administered as a single dose of 10. 0 mg per kg. body weight to a total of 4,198 Ascaris infected cases selected out of 4,436 (41. 6%) positives, who were screened from the total 10,660 collected stool specimens. Of these, only 3,169. cases were followed up after treatment to provide an analysis in this study. Incidentally 161 cases with concomittently infected hookworm were also subjected to assess the efficacy of pyrantel pamoate against A. duodenale. The egg negative conversion rate on A. lumbricoides was 95.3%, and on A. duodenale, 97.5% four weeks following treatment. In failed cases, the egg reduction rates on both of the infections were 97.6% and 97.3% respectively. No side effects and no problem in drug administration were demonstrated. It is concluded that this study confirms the high efficacy of pyrantel pamoate in the treatment of Ascaris lumbricoides and Ancylostoma duodenale infections and also proves the acceptability and safety of this drug in the mass treatment of ascariasis in a population with relatively high worm burden.

독일 문예이론이 한국문학에 끼친 영향에 대한 비판적 고찰 : 게오르크 루카치의 경우

Georg Lukacs ist einer der einflußreichsten Literaturtheoretiker in Korea. Bis Mitte der 80er Jahre des letzten Jahrhunderts konnte man aber uber ihn nicht offentlich diskutieren wegen der Unterdruckung der Linden durch die militarische Diktatur. Und es ist gerade die Eignetumlichkeit seiner Rezeption in Korea, daß diese eher von den linken Literaturkritikern geleistet wurde als von den fahigeren Germanistikern. Unter den Einspruchen gegen Lukacs' Theorie spielten wohl die von Brecht und Adorno die vichtigste Rolle in Korea. Brechts Kritik, daß Lukacs Klassenkampf vergißt, reproduziert sich hier, wie im Ostblock, als die gegen seinen sogenannten Revisionismus, die spater in der leninistischen Partei-Literaturtheorie Resultiert. Letztere ruft heftige Reaktion auf der Seite der liberalistischen Kritiker hervor, die in dem Radikalismus der Literaturbewegung nur die verdeckte Begierde nach Hegemonie sehen mochten. Die Forderung der Gestaltung des Typischen -ein Kern von Lukacs' Realismustheorie- bildet die widerspruchslose Grundlage der Debatten zwischen radikalen Kritikern der 80er jahre, obwohl man mit zima den Verdacht der Eindeutigkeitsmythologie erheben kann, hinter dem Adorno steht. Aber jeder Vertreter der Literaturgruppen gibt andere Konstellation von Typen zu erkennen als die in der damaligen Situation der Veranderungsbewegung treffendste, was ein notwendiges Resultat der Theorie des Typischen ist, die immer mit der Wirklichkeit konfrontiert werden muß. Und die literaturpolitische Anregungskraft des Radikalen verfluchtigte sich mit der Verdunkelung der Perspektive der baldigen Umwalzung in Korea. Aber die wesentlichen Elemente von Lukacs' Literaturtheorie haben großere Tragjahigkeit und Dauerhaftigkeit bewiesen als jenes System, das ihm mehr Ehre gegeben hat als den Vorwurf des Revisionisten. Deren Lebenskraft stammt aus der repressiven kapitalistischen Wirklichkeit, und zwar aus ihrer Elastizitat, die von der materialistischen Dialektik nicht getrennt werden kann, und die sich z. B. in den differenzierten Bestimmungen vom Sieg des Rialismus klar darstellt, der auch in Korea einen heißen Streitpunkt gebildet hat.

The fundamental way in which fiber reinforced composites differ from conventional engineering materials such as metals is that the material properties are highly directional. This anisotropy affects the way in which the materials are used and the way in which the directions of the individual plies are selected. The stiffness properties needed for a plane-stress analysis are the modulus in the fiber direction E11, the modulus transverse to the fiber direction E22, the in-plane shear modulus G12, and one of the in-plane Poisson ratios ν12 and ν21. These properties are routinely characterized by laboratory experiments. Testing methods are examined to investigate mechanical characteristics of advanced composites, and basic properties are measured. Especially, the testing preparation, test processing, and results are examined in detail.

The mass treatment trial with low dosage of pyrantel pamoate against Ascaris lumbricoides infection was conducted to school children in rural areas of Korea. A comparative trial in the use of piperazine salt, santonin-kainic acid complex in the treatment of ascariasis was also attempted to evaluate the efficacy of' pyrantel pamoate. A total of 804 Ascaris infected school children selected out of 822-positives, who were screened from the total 1, 699 collected specimens, were classified into 7 groups. One of the three kinds of anthelmintics, i.e., pyrantel pamoate, piperazine adipate and santonin-kainic acid complex was administered to each group according to the planned regimen. For the evaluation, the egg negative conversion rate(cure rate) and egg reduction rate were calculated 4 weeks after treatment on 623 follow-up cases with the obtained results from the stool examinations (Cellophane Thick Smear Method and Stoll's Egg Counting Technique). The results obtained were; 1. The egg negative conversion rate was the highest in pyrantel treated groups (Group 1, 2, 3), santonin-kainic acid complex treated group (Group 7) coming next, and the lowest in piperazine treated groups (Group 4, 5, 6). 2. The reduction rates were also obtained just as the same order of the above results. 3. Among the pyrantel pamoate treated groups, the low dosage groups (Group 2 8: 3) showed 90.6% and 85.7% of negative conversion rate, and 99. 2% and 98. 2% of reduction rate respectively, while 94.1% of negative conversion rate and 97.9% of reduction rate were obtained in the conventional dosage group (Group 1). 4. On the analysis of efficacy in the groups treated with piperazine adipate, the best results were. shown in 2 or 3 consecutively treated groups (Group 4 &.- 6) under the supervision of qualified doctors, and the worst was in the group treated with 2 consecutive administration by teachers without supervision (Group 5). 5. The side reactions were so negligible in all the trial groups that none of the treated cases complained about the known side effect of those anthelmintics. From the present study, it can be suggested that the pyrantel pamoate is the most effective among three drugs, and also be recommended to apply the low dosage schedule of pyrantel pamoate in the masstreatment of ascariasis to reduce the expense of masstreatment.

In this paper, we has studied frequency dependence of impedance of FeCoB amorphous magnetic films. First, we investigated optimal composition and sputtering conditions for fabrication of zero magnetostrictive amorphous magnetic films. (Fe_(1-x)Co_x)_79Si_2B_19 was selected as the basic composition and then, the films were fabricated with x=0.94 and 0.95 respectively by using sputtering method at high frequency. In order to relieve the internal pressure and derive the magneto-anisotropic. we annealed the films in about 150[Oe] of magnetic field and in the range(280℃, 300℃ and 320℃ respectively) of crystallization temperature(360℃). In addition, we annealed the films under non-magnetic field and near crystallization temperatures (283℃/30min, 400℃/30min and 400℃/1hr respectively) in order to decrease magnetoanisotropic. Then, we investigated magnetic properties including magneto-impedence and inductance. As the results, we found excellent magnetic characteristics and high impedence changing rate(4.52[%/Oe]) when we fabricated a sample under the condition that input power 400[W], Ar gas pressure 6.4[mTorr]. sputtering time 30[min] and annealing time 30[min] at 300[℃] in 150[Oe] magnetic field Especially, the impedence changing rate which was basic characteristic of Ml element was 4.52[%/Oe] for x=0.94. Moreover, the inductance values of the samples annealed at 400[℃/30min] were higher by 132[%] to 197[%] than those of the non-annealed samples. In addition, the quality factor Q was below 0.7 for all samples. Consequently, we find that the zero magnetostrictive amorphous magnetic film can be used as a magnetic sensor material.

본 연구는 독일 Schumacher의 1m 크기의 세라믹 캔들 필터가 1개 설치된 실험장치를 구성하여 집진시 단일 필터 주위에서의 분진 속도분포를 PDPA를 이용하여 측정하고, 분진층의 유무와 분진 투입 위치에 따른 분진 속도분포의 변화를 관찰하였다. 측정 결과 집진이 계속되어 분진층이 발달함에 따라 접진 속도가 감소됨을 알 수 있었다. 특히, 투입구가 위치하는 필터표면에서 집중적으로 분진층이 발달하여 이곳에서의 분진 속도 감소가 크게 나타났다. 그리고 필터내부와 압력용기부사이의 압력 차에 의한 필터 표면에서의 분진 속도 평균값은 0.28m/sec 이었다. 또한 분진 투입을 암력용기부 하단에 위치한 투입구로 투입하였을 때 필터 주위의 분진의 고른 속도분포를 관찰할 수 있었다. The experimental set-up with a 1m long ceranic candle filter of Schumacher(Germany) was built in this work. The dust velocity field around the filter was measured using PDPA. The effects of dust cake laver and dust inlet position on the dust velocity field were also analyzed. It was found that the filtration velocity decreases as the dust cake builds up on the filter. The filtration velocity largely decreases around the filters near the dust inlet since the dust cake tlevelops fast there. The average dust velocity on the filter due to the pressure difference through the filter was measured to be 0.28m/s. More uniform dust velocity field around the filter was obtained when feeding dust in a lower position of the pressure vessel.

At here, we investigated the historical background, current stage, and concrete therapies of altematives in cancer therapy. We obatined the conclusion below. 1. Alternative medicine(AM) is a unothodoxial medical physiology, medical practice or intervension that overcome the side effects. faults, limits of coventional medicine. 2. Recentely, as emerging New-age movement, collgpse of Decarte's mecanical cosmology, and emphasis on patient rights, the interest of AM is increased, and foreign & domestic use rates of AM are risen. 3. After coventional medicine in cancer therapies tha depends on poerations, radiations, and chemotherapy is bounded, Altematives in cancer therapy are rapidly developed, and the majority of users are often considered satisfactory. 4. Alternatives in cancer therapy are classified six boundaries; Diet and Nutrition, MInd-body Technique, Integrated System, Pharmacologic and Biologictreatments, Immuno Enhanced Therapy, Immuno Enthaced Therapy, Natural and herbal medicine. 5. Looking at contents of Alternatives in cancer therapy, we get to know most of them are similar to the treatment of oriental medicine in holistic method, therapy, philosophy. If we synthesize the alternative medicine's treatment mentioned above and investigate it with oriental medical viewpoint, that may help us approach the conquest of cancer and improve the rate of cure. that may help us approach the conquest of cancer and improve the rate of cure. 6. It is certain that foreign AM will be imported reversely, and we must prepare for rebuilding of Korean traditional AM systemically, investing for activity positively, making national policy for medical system.
