개인차를 고려한 미술과 교수·학습 연구

이형구,정경화 부산교육대학교 교육대학원 2004 논문집 Vol.6 No.-

2000학년도부터 연차 적용되고 있는 제 7 차 교육과정은 학습자 중심의 교육을 그 핵심으로 하고 있다. 다원화, 전문화, 정보화로 특징지을 수 있는 미래사회에서, 기초적인 학력 외에도 다양하고 우수한 학습능력을 찾아내어, 창의력과 개성을 갖춘 인격을 키워내는데 의의를 두고 있다. 이는 획일적 교육에 대한 일종의 반성으로, 현재의 교육을 개선하고자 하는 의도이며 새로운 방향의 교육추세에 맞춰나가는 것으로 볼 수 있다. 이에 따라. 국어, 수학, 과학, 영어, 사회와 같은 지적 능력 중심의 교과에서는 학습 능력과 속도의 차를 고려하여 수준별 교육과정을 운영하도록 하고 있다. 그러나, 도덕, 실과, 체육, 음악, 미술의 5개 교과에서는 국가수준의 교육과정 편성운영에서는 차별화가 되지 않았지만, "학생의 능력, 적성, 필요, 흥미에 대한 개인차를 최대한 고려한 수업으로 학생 개개인의 성장 잠재력과 교육의 효율성을 극대화 할 수 있도록"(교육개혁위원회, 1996: 43)이란 기술을 통해 학생의 다양한 특성에 적합한 교육을 요구하고 있다. 수준별 교육과정을 채택하지 않은 미술과의 경우, 학습자의 다양한 적성과 흥미를 교수 학습 상황에서 어떻게 고려하여 전개할 것인가에 대한 연구가 필요하게 되었다. The main object of the 7th curriculum applied annually since 2000, is the learner-centered education, which has been introduced in the demand that the education should change in order to lead the society of an information-oriented, specialization and variety by bringing up the creative and talented students. In five subjects - ehics, practical course, physical exercise, musics and art. The basic principle to educate the learners considering the individual differences is set up but regrettably there is no detailed explanation on how to educate the learners. I think there are much problems in teaching the students regarding the individual differences in the reality of many students and short teaching time. This study is to reveal the individual differences in the art course of elemenatry school, to develop the teaching and learning method balancing the minimizing of individual differences in one way and maximizing of that in the other way. And also this study is to show the evaluation on the leaners' special characters by the various instructors and methods from the various viewpoint. In chapter Ⅰ, This study present the object, necessity and outline of contents on the education regarding the individual differences. In chapter Ⅱ, This study analyze the individual teaching system, open education and education by students' study level. And this study present the general idea of the education considering the individual differences. Also, this study refer to the various theory - Aptitude Treatment Interaction, Adaptive Instruction. Multiple Intelligences, constructivism education of individual differences. In chapter Ⅲ, This study divide the factors causing individual differences into 3 ones - stuty ability, interest and concern, and study pattern - and present the guidance of the teaching and learning method and evaluation in accordance with these factors. I make emphasis differently among the major changing factors and minor ones in the course of teaching and learning. In order to evaluate the students considering the individual differences, this study present the variety of the evaluation point of time (diagnosis evaluation, process evaluation, result evaluation), variety of the evaluators (instructor's evaluation, self evaluation, interactive evaluation), variety of method (study paper, study report, observation, questions and etc). Also, in order to secure the objectivity, individual evaluation present 3 level - high, medium and low - and present the teachers' reflection in the viewpoint of improvement of the instruction method. Lastly this study present method and standard of portpolio evaluation which help grasping the general development and character of a student. In chapter Ⅳ as a result, this study emphasize the effort of gradual change toward the implementation of the education considering the individual differences.

블록체인 기반의 비트코인 거래를 위한 정책적 시사점

최경화 ( Kyung-hwa Choi ),이경현 ( Kyung-hyune Rhee ) 한국정보처리학회 2018 한국정보처리학회 학술대회논문집 Vol.25 No.1

최근 우리나라의 비트코인 거래량이 폭발적으로 증가하면서 블록체인 기반의 비트코인에 대한 관심이 높아지고 있다. 비트코인에 적용된 블록체인 기술은 중개기관의 개입이 없는 분산된 지급 형태로 위‧변조의 우려가 적고 거래가 간편하나 불법자금, 탈세, 이용자 도산 등의 문제가 발생할 가능성이 있다. 이에 본 논문에서는 블록체인 기반의 비트코인 거래에서 도출된 정책적 시사점과 향후 정책 도입 방안을 제언한다.

NiAs형 결정 구조를 갖는 두께 1000Å 자성 박막을 진공 증착방법으로 제작하고 시료 진동형 자기계를 사용하여 자기 특성을 조사한다. 증착시 유리 기판의 온도를 일정하게 유지하면서 증착방법은 Cr-Te-Cr 연속증착에 의하고 진공도는 ?? Torr를 유지한다. CrTe 박막으로서의 조성 여부를 확인하기 위하여 X선 회절장치를 사용하여 관측한다. 제작된 박막에 관하여 자화곡선을 관측하여 항자력, 포화자화도, 큐리온도를 측정하고 자화용이축이 C축이라는 것을 확인하였다. 그 박막의 자기적 성질들의 온도 의존성을 293 K에서 333 K 범위에 걸쳐 조사해 보았다.

건강한 한국인 여성에서의 골밀도와 혈청 렙틴의 연관성

이유미,김대중,김세화,안철우,차봉수,김경래,이현철,임승길 대한내분비학회 2003 Endocrinology and metabolism Vol.18 No.2

연구배경: 혈청 렙틴은 식욕억제 효과와 여러 기관에서의 기능 외에도 골대사에 중요한 영향을 주는 인자로 알려져 있다. 그러나 렙틴의 골대사에 관여하는 각 세포와 실제 사람의 골밀도와의 관계에 대한 논란은 많다. 이에 건강한 한국인 여성에서의 골밀도와 혈청 렙틴과의 관계를 살펴보고자 하였다. 방법: 만성질환이 없는 67명의 폐경 전 여성과 73명의 폐경 후 여성을 대상으로 하여 요추부 및 대퇴경부의 골밀도를 DNA를 이용하여 촬영하고 혈청 렙틴을 측정하여 비고 분석하였다. 결과: 폐경 후 여성에서만 요추부 골밀도와 혈청렙틴이 양의 상관관계를 보였으며 이 관계는 연령과체지방지수 및 폐경기간을 보정한 후에도 양의 관계를보이는 경향이었다. 또한 가장 낮은 혈청 렙틴 농도를 보인 폐경 후 여성의 경우 높은 농도를 보인 여성들에 비해 의미 있게 낮은 요추부 및 대퇴경부 골밀도를 보였다. 결론: 건강한 한국인 여성에서의 혈청 렙틴은 골밀도와 약한 양의 상관관계를 보였으나, 폐경 상태에 따라 달라짐을 볼 수 있었다. Background: Leptin is known to affect bone metabolism both centrally and peripherally. This study was performed to investigate the relationship between leptin and bone mineral density (BMD) in healthy premenopausal and postmenopausal Korean women. Methods: 140 women were recruited for a routine health check-up. Anthro-pometric and biochemical data were checked as usual. BMDs were measured by dual x-ray absorptiometry of the spine and femur in 67 premenopausal women and 73 postmenopausal women, in addition to their serum leptin levels. Results: Serum leptin level showed no correlation with BMD in premenopausal women, but there was a positive correlation betwen serum leptin and spinal BMD in postmenopausal women (r=0.468, p<O.001). After the correcting for age, body mass index, and duration of menopause, the serum leptin level and BMD still showed a positive correlation(r=0.217, p=0.088) although weak The women in the lowest quartile of serum leptin level showed significantly lower lumbar and femoral neck BMD. Conclusion: Leptin level seems to have a weak relationship with BMD showing different features in premenopausal and postmenopausal women (J Kor SOC Endocrinol 18: 177-183, 2003).

Synthesis, Cytotoxicity and Topoisomerase II Inhibitory Activity of Benzonaphthofurandiones

Rhee, Hee-Kyung,Kwon, Young-Joo,Chung, Hwa-Jin,Lee, Sang-Kook,ParkChoo, Hea-Young Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.7

Benzonaphthofurandiones containing four coplanar fused aromatic rings were synthesized and evaluated for their cytotoxicity against five human cancer cell lines, and their inhibitory activity on topoisomerases. These benzonaphthofurandiones were prepared by condensation of 2,3-dichloronaphthoquinone and three aromatic diols with base catalysts in alcohol. The synthesized compounds were o-alkylated with six dialkylaminoalkyl halides. The hydroxy derivatives (8a-8g) exhibited relatively potent cytotoxicity among the prepared compounds. These compounds were evaluated as excellent inhibitors against topoisomerase II (topo II). Especially, the hydroxy analogue with branched methyl side chain (8e) showed high cytotoxicity against cancer cell lines and good inhibitory activity on topo II.

The purpose of this study was to investigate change of physiological antioxidative system according to the time in streptozotocin-induced diabetic rats. Sprague-Dawley male rats weighing 150±10gm were randomly assigned to one normal and five STZ-induced diabetic groups. Diabetic groups were classified to experimental period. Diabetes was experimentally induced by intravenous injection of 55 mg/kg of body weight of STZ in citrate buffer(PH 4.3) after 6 weeks feeding of three experimental diets. Animals were sacrificed at 0, 3, 6, 12, 18th days of diabetic states. 1. Activity of superoxide dismutase(SOD) in liver was increased in that of diabetic mellitus(DM) groups at 3th day but that of DM groups was not significant from 6th day according to period. Glutathion peroxidase(GPX) was significantly decreased in DM groups from 6th day 2. Reduced glutathione(GSH) contents in liver significantly decreased in diabetic groups from 3rd day compared with those of DM groups according to the period. Oxidized glutathione(GSSG) was higher from 6th day. GSH/GSSG ratio was significantly lower than that of normal group from 3rd day to all experimental period 3. Contents of vitamin E in liver of DM groups were significantly decreased compared with that of normal group from 6th day. 4. Lipid peroxide(LPO) contents in liver of DM groups were significantly increased compared with that of normal group from 3rd day. The present results indicate that STZ-induced diabetic rats were reduced by antioxidative defense system and taken by peroxidate damage in tissue compared with normal group from 3rd day or 6rd day after injection STZ. It lended to acceleration all diabetic groups but no significance according to the experimental time.
