The purpose of this study was carried out an epidemiological survey on the prevalence rate of the canine heartworms in Seoul City and the districts of Pa-Ju, Seong-Nam and Po-Chon in Kyonggi province of Korea from September 1994 to the end of September 1995. The blood samples from 292 male and 193 female dogs (pet, 363 ; fighting dogs, 60 ; working dogs, 62) were examined for the adult heartworms cuticle antibodies using the enzyme-linked immunosorbent assay (ELSA) kits. The test was designed to detect the antibodies of the host against the specific cuticle antigens produced with the adult heartworms.

이윤종,기우항,김영호,정원우,양승영,강용희,안병호,임성규,윤일희,김중욱,강동진 경북대학교 과학교육연구소 1996 科學敎育硏究誌 Vol.20 No.-

The status of facilities, management of the experiment, practices, and Science education teaching method in middle school have been investigated. The present status and reasonable management of middle school science education have been grasped from the questionaires. The results are as follows : The reasonable management for expeiments and practices of science education were scanty in the middle school around the urban and rural schools owing to the shortage of facilities and equipments, crowded class, excessive classes, work for teachers, excessive contents of present textbook and insufficience of administrative support etc. The current teaching method of middle school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of teaching method. Desirable directions for the improvement of present status of middle school science education were proposed in this paper.

An experimental study on the preparation of monolithic porous polymers by environmentally friend process in supercritical carbon dioxide has been carried out. Polymerization mixture composed of a cross-linking monomer, initiator and functional co-polymer was charged in the reactor with sapphire window. After the system was purged with a flow of CO₂ for 15 min, the reactor was pressurized with liquid CO₂ up to 100 bars. The reactor was isolated from and placed back to the system via quick connector for shaking until the mixture had become fully homogeneous. The reactor was then heated and pressurized to the required reaction conditions and left overnight. After cooling and CO₂ evacuation, the polymer was removed from the reactor as dry, white, continuous monoliths. The effect of experimental conditions on the physical properties of porous polymer was systematically examined, and it was found that monomer content had a major effect on the physical properties of the polymers.

The purpose of this study is to in-vestigate the effects of gradual and radical exercise load on the treadmill for PH, Sugar and Lactate in Blood by selecting 14 subjects in H university, All subjects began exercise by 6mPH for 4 minutes at start and increased exercise speed up to HR 140 by increasing every minute as gradual load. And subjects began exercise by 9mPH at first and increased load up to HR 140 as radical exercise load. The results are as follows: (1) In PH in Blood, gradual exercise load is lower than radical training in all subjects. (p<0.05) (2) In Sugar in Blood, radical exercise load is higher than gradual exercise load in all subjects. (p<0.05) (3) In Lactic Acid in Blood, gradual training is higher than radical exercise load in all subjects. (p<0.01) (4) In Lactic Acid, all subjects showed high value and its is also in Sugar, than the method of exercise load is according to anaerobic energy metabolism.

발효온도에 따른 백김치의 발효 특성에 관한 연구

강근옥,이성희,이현자 안성산업대학교 1997 論文集 Vol.29 No.2

백김치 담금시 가장 적절한 발효 온도를 알아보기 위하여 소금농도를 1.0%로 하여 10, 20, 30℃에서 각각 발효시켜가며 물리화학적 및 관능적 성질을 측정하였다. 발효시 pH와 총산도의 변화를 보면 온도가 증가함에 따라 pH 감소 속도는 빨랐으며 총산도 역시 pH와 같은 경향으로 증가하였는데 30℃에서 pH4.2-3.6사이의 총산도는 pH4.2에서 0.13%, pH4.0에서 0.20%, pH3.8에서 0.32% 그리고 pH 3.6에서는 0.44%로 pH가 낮을수록 총살도가 증가함을 알 수 있었다. 그리고 관능적 성질은 전체적으로 30℃가 다른 두 온도에서 보다 좋게 평가되었으며 p>0.05의 범위에서 유의성을 보였다. 또한 백김치의 가장 적절한 pH를 찾아내기 위하여 pH4.2-3.6에서 관능적 특성을 평가한 결과 pH3.8 부근이 가장 좋게 평가되었다. 이상의 결과를 종합하여 보면 백김치쥬스를 제조하기 위한 가장 적절한 백길치액의 조건은 소금농도 1.0%의 백김치를 제조하여 30℃에서 발효시키는 것으로 pH3.8부근, 총산도는 0.2, 0.3%의 백김치가 가장 기호도가 높은 것으로 나타났다. 이는 보통 배추김치의 경우 적숙기는 pH4.2, 총산도는 0.5-0.6%로 낮은 온도에서 발효시킨것이 가장 좋은 것으로 알려져 있는 것과는 다른 결과로 발효 온도가 높고 pH와 총산도는 일반 배추김치보다 낮은 것이 좋게 평가되었다. The Baik Kimchi, a kind of watery Kimchi, was fermentation at different temperatures and studied for its effection on pH, total acidity and organoleptic properties. The Kimchi was prepared by fermentation of brined Chinese cabbage having 1.0% NaCl concentration at 10, 20 and 30℃ with addition of water and some fresh spices. The higher temperature resulted an increase in fermentation rate in terms of pH and total acidity. Sensory evaluation on the Kimchi showed that fermentation at 30℃ was more acceptable when its pH reached 3.8 and acidity of 0.2~0.3%. This optimal pH and acidity were somewhat lower than those values of ordinary Kimchi which is in the range of pH 4.0~4.2 and acidity of 0.5~0.6%.

강성준,황희용 강원대학교 정보통신연구소 2008 정보통신논문지 Vol.12 No.-

In this paper, we analyzed the dual mode ring resonator of the recently reported Balun-BPF by network Y-parameter analysis. Using the derived Y-parameter and slope parameters, we also verified that the balun conditions of the Balun-BPF at center frequency. This makes it easy to design the Balun-BPF with arbitrary characteristics.

원격영상강의에서 발생하는 상호작용의 빈도와 유형이 학습 동기유발에 미치는 영향

강명희,김서영 한국교육정보방송학회 1996 교육정보미디어연구 Vol.1 No.2

본 연구에서는 원격영상 강의를 시범적으로 실시하고 있는 '한국방송대학교'의 2개 강좌-사회과학 계열 1개 과목과 인문과학 계열 1개 과목-를 모국과 자국 모두 관찰함으로써 원격교육에서 상호작용이 어떠한 빈도와 형태로 나타나고 있으며 이는 학습자의 동기유발에 어떠한 영향을 미치는가를 조사하였다. Flanders의 상호작용 분석법을 활용하여 비디오로 촬영한 강좌 상황을 분석한 결과는 다음과 같다. (1) 사회과학 계열의 과목이 인문과학 계열 과목보다 교사 대 학습자 (T-S), 학습자 대 교사(S-T), 학습자 대 학습자(S-S) 상호작용이 많이 일어난 것으로 관찰되었다. (2) 모국과 자국의 비교에서는 모국이 자국에 비해 일반적으로 상호작용이 많이 일어나며, 그 유형은 교사 대 학습자(T-S) 상호작용이 주를 이루었다. (3) 상호작용이 많은 것이 학습자의 동기를 전반적으로는 유발하지 않았으나. T-S 유형은 학습자 의 주의력에 S-T 유형은 학습자의 자신감에 의미있는 영향을 주는 것으로 나타났다. The purpose of the study is to investigate the frequencies and patterns of teacher-student interaction and gain insight on the student motivation regarding interaction through two video conferencing courses being implemented at Korea Open University during the fall semester of 1995. The results revealed the lecture K provided much more interaction than lecture M. In lecture K, teacher-student interaction was prevalent. On the other hand, student-teacher interaction was more observed in lecture M. The on-site location showed more interaction than remote-site in both lecture. On-site location, teacher-student interaction was more frequently observed and student-teacher interaction was shown more in remote-site. Analysis of the relationship between interaction pattern and student motivation revealed that there was no correlation between interaction pattern and student motivation. All pattern of interaction could not be directly correlated to overall students motivations. However, it was elucidated that the Teacher-Student pattern enhanced attention of the students and the Student-Teacher pattern positively influenced confidence of the students.

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.
