노태희,차정호,왕혜남 한국초등과학교육학회 2004 초등과학교육 Vol.23 No.1

이 연구는 제7차 교육과정기의 과학 교과서와 실험관찰 교과서에 제시된 삽화를 성역할 고정관념 측면에서 분석하고 6차 교육과정기의 과학 교과서와 비교하였다. 교재에 나타난 삽화에서 성별에 따른 등장인물의 빈도를 세고, 활동 유형을 분석하였다. 연구 결과는 다음과 같다. 1) 과학 교과서의 전체 삽화 수는 6차에 비해 7차에서 2배 정도 증가하였다. 2) 아동의 경우 학습활동에서는 성에 관계없이 등장 빈도가 대체적으로 균형을 이루었지만, 학습의 활동에서는 남학생의 등장 빈도가 여학생보다 더 높았다. 3) 행동 특성에서는 남녀 학생 모두 적극적으로 묘사되었고, 소극적으로 묘사되는 여학생의 비율은 6차 과학 교과서에 비해 감소하였다. 4) 성인의 경우에는 남성의 등장 빈도가 여성보다 높게 나타났다. 5) 가사 활동을 하는 모습에서는 여성의 등장 빈도가 40%로 높게 나타난 반면, 남성은 드물게 나타났다. The illustrations in elementary science textbooks and experimental workbooks based on the 7th national curriculum were analyzed for gender-role stereotyping, and compared with those of the 6th curriculum. The frequencies of men and women who appeared on text illustrations were counted and the types of roles assigned to males and females were investigated. The results were as follows. 1) The 7th national curriculum textbooks contained double the number of illustrations in the textbooks based on the 6th curriculum. 2) Boys and girls were illustrated in 'learning activities' with equal frequency, but boys were more frequently represented than girls in illustrations of 'other' activities. 3) Both boys and girls were generally depicted in 'active' processes and the ratio of 'passive girl' illustrations decreased as compared with the 6th national curriculum. 4) Male adults were more frequently represented than female adults in both textbooks and experimental workbooks. 5) 40% of female adults were illustrated doing housework, while male adults were rarely illustrated in such a role.

The relationship between adolescent children and parents has a profound effect on not only the adolescents development into healthy adults but also the psychological welfare of the parent. A program focused to improve adolescents relationship with parents has not been developed until now. To achieve the educational goals enhancing mutual understanding, it is more effective to educate both the parents and adolescent childern. Thus, this study developed and carried out a program in which adolescent children and mothers, being fully in charge of raising children, participated. The study analyzed the program effects after implementing on 6 pairs of adolescent children and mothers. The results are as follows: 1) adolescent children and mothers placed high values on the fact that they can understand each other well, 2) both parties accepted each other by recognizing the inevitability of the generation gap, and 3) the program gave them a chance to admit that they should try to communicate openly. Most of all, adolescent children could find self-confidence while mothers could collect valuable data essential to raise children and build a new mother's role model adapting to social changes.

류주희,차정호,김인환 대구대학교 사범대학 부설 교육연구소 2008 敎育硏究 Vol.3 No.2

본 연구에서는 과학 전자교과서의 동기유발전략을 분석하였다. 분석에는 Keller의 ARCS 동기이론이 사용되었다. 에듀넷의 중학교 1학년 화학 내용을 선택하였으며, 두 명의 연구자에 의해 동기 유발과 동기 유지 측면에서 분석되었다. 분석자간 일치도는 90%이상이었다. 연구 결과, 각 동기 전략이나 학습단계에 대한 차이는 없는 것으로 나타났다. 가장 많이 사용된 전략은 “사진의 패턴이나 글자를 돋보이게 하거나 거꾸로 나타내기”, “점진적으로 드러내기를 통한 교수 조각 맞추기”, “제목이나 키워드에 밑줄 긋기, 이탤릭체 또는 큰 글자크기를 사용하기”였다. “학습자의 집중력을 빼앗는 요소”는 가장 적은 빈도를 나타내었다. 학습의 마지막 단계에서는 전략 사용 빈도가 학습의 처음 단계에 비하여 상대적으로 낮았다. In this study, learning motivation strategies of the science e-textbooks, were analyzed. Keller's ARCS model was used for analysis. The 7th-grade chemistry contents ware selected from the EDUNET (edunet4u.net), then analyzed in aspect of gaining and sustaining attention by two researchers. Intercoder agreement of the analysis was over 90%. The results indicated that the frequencies of each motivation strategies were not different by learning stages. The most frequent strategies were "use inverse and flash in text and patterns in pictures as attention getters", "keep instructional segments relatively short with progressive disclosure", and "use underlines, italics, or bigger font sizes for the headings or key words". "Avoid disfunctional attention-getting effects such as a flashing word that distracts learners' concentration" was the lowest frequent strategy. At the end stage of learning, frequencies of the strategies were relatively low than those of early stage of learning. Educational implications are discussed.

녹차 및 결명자 추출물의 교정용 브라켓과 치면 사이의 경계부에서 분리된 mutans streptococci에 대한 항균작용

임성훈,서정순,윤영주,김광원,유소영,김화숙,국중기,이병래,차종희,박재윤 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.5

본 연구는 치아우식증에 관련된 Mutans streptococci 표준균주 및 임상분리 균주의 성장억제를 유도할 수 있는 천연 생약추출물을 검색하기 위하여 실시되었다. 녹차추출물은 CHMC-2032를 사용하였으며, 결명자 추출물은 50% 에탄올을 이용하여 얻었다. 이들 추출물의 Mutans streptococci 표준균주 및 교정환자들에서 브라켓과 치면 사이의 경계부에서 분리된 각각 10 균주씩의 S. mutans 및 S. sobrinus에 대한 최소성장억제농도를 액체배지 희석법으로 구하였다. 그 결과 CHMC-2032의 S. mutans 및 S. sobrinus의 표준 균주, S. sobrinus의 대부분 임상분리 균주에 대한 최소성장억제농도는 5 mg/ml이었다. 그러나 결명자 추출물에 의한 S. mutans 및 S. sobrinus에 대한 세균 성장억제 효과는 미미하였다. 본 연구 결과 치아우식증의 예방적 측면에서 결명자차보다는 녹차를 마시는 것이 유리하며, CHMC-2032를 이용하여 구강양치용액을 제조하여 사용할 경우 교정환자를 포함하여 대부분의 사람에게서 치아우식증 예방 효과가 있으리고 추정된다. Mutans streptococci is the major causative factor in dental caries. Especially, orthodontic patients with fixed appliance are a risk group for dental caries. Because fixed appliances attached on teeth may change the environment of dental plaque, the enamel decalcification or dental caries around the bracket and band is a major side effect of orthodontic treatment. The aim of this study was to search plant extracts that have antimicrobial effect on mutans streptococci. Seed-extract of Casio tora were prepared with ethanol and CHMC-2032, the leaf-extracts from Camellia sinensis extract, was obtained extract, 2 type strains and 20 clinical isolates of mutans streptococci isolated from the interface between orthodontic brackets and tooth surfaces in the orthodontic patients were used in this study. The minimal inhibitory concentration of CHMC-2032 was 5 mg/ml on the S. mutans KCTC 3065, S. sobrinus KCTC 3088, and 8 clinical isolates of S. sobrinus. However, there was no antibacterial effect of seed-extract of C. tora on mutans streptococci. These data suggest that green tea may be more effective than the tea prepared from C. tora in the prevention of enamel decalcification or dental caries around brackets.

The main goal of this program is to build a healthy adolescent culture by broadening the understanding of adolescents and recognition of the environment as well through the development of educational programs centering on the domains of peer relationships, intimacy in dating relationships and sex, leisure activities, and consumption life of adolescents. The program was carried out to 10 young boys and girls for two days/one night and the major findings of the effects of the program through a qualitative evaluation were as follows: First, the program provided adolescents with a proper opportunity to promote a sense of self-confidence through the self-reevaluation process. Secondly, the program provided adolescents with a chance to firmly recognize to become good friends with others though the enhancement of self-esteem, which helped them to build a healthy peer relationship. Thirdly, adolescents were able to promote their views on sex and sexual decision-making by acquiring a proper knowledge of intimacy in dating relationships and of sex, and by candidly expressing their own opinions on sex with instructors. Fourthly, the program provided adolescents with an opportunity to look back on their leisure life with family members which had been neglected thus far and to renew their recognition of active leisure activities. Fifthly, the program provided adolescents with a chance to reflect on their unplanned consumption life and to be firmly determined to refrain from impulsive purchasing and extravagance.

오원석,이차수,오규실,정원일,정재용,정다히,정규식 한국임상수의학회 2003 한국임상수의학회지 Vol.20 No.4

To investigate the renal effects of enrofloxacin administration on rats induced with dehydration or hyperoxaluria, male rats were treated with enrofloxacin of 50 mg to 500 mg/kg b.w.. The microscopical observations of kidney and urine sediment were carried out in the experimental groups. The result obtained were as follows; The male rats deprived of water for 72 hours and administered with enrofloxacin. As enrofloxacin administration dose was increased, clinical signs such as loss of appetite, depression, weakness, and loss of urine output became more severe. In the histopathological findings, there were hyperemia and hemorrhage in renal cortex, vacuolation and necrosis of renal tubular epithelia, proteinous casts within renal tubules. The male rats were orally administered with sodium oxalate and injected with enrofloxacin for 7days. As enrofloxacin administration dose was increased, clinical signs such as the loss of appetite and water consumption, and weakness became more severe. In the histopathological findings, there are hemorrhage of glomeruli and cortical hyperemia, vacuolation and necrosis of tubular epithelia, proteinous casts in renal tubules. In the microscopical findings of urine sediment, there are calcium oxalate crystal (diamond-like type) and magnesium ammonium phosphate crystals (rhomboid). The male rats were intraperitoneally injected with sodium oxalate and administered with enrofloxacin for 7days. As enrofloxacin administration dose was increased, clinical signs such as the loss of appetite and water consumption, weakness were more severe. In the histopathological findings, there were hyperemia and hemorrhage in both glomeruli and renal cortex. Severe necrosis of renal tubular epithelia, bluish materials within renal tubules were also found. In the microscopical findings of urine sediment, there were many calcium oxalate crystals. The present results suggest that enrofloxacin has some injurious effects in rats having dehydration or hyperoxaluria, and clinically, we should consider these renal injury effects when we use enrofloxacin in patients accompanied renal disease, dehydration and hyperoxaluria conditions.
