The level-based task learning had an effect on enhancing the math achievement of enrichment and ordinary classes. Besides, the analysis of mathematical attitude change showed that the level-based task learning took effect in the experimental class in every domain, including self-confidence, flexibility, will power, reaction and value, while it made little difference to the comparative class. The findings were as follows in detail. 1. The Outcome of the Achievement Test 1) The Enrichment Class In the first two tests, there were little differences in the enrichment class, But the disparity between the experimental and comparative classes became larger as this study advanced with 4.3 for the third test, 6.4 for the fourth and 6.1 for the fifth. 2) The Ordinary Class In the first to fifth achievement tests, the ordinary class made less difference than the enrichment class did. But there appeared some effect as this study progressed, since the mean grade disparity between the experimental and comparative classes was 2.1 for the first test, 3.5 for the second, 3.9 for the third, 4.4 for the fourth and 6.3 for the fifth. 3) The Supplementary Class The supplementary class showed no big difference in the first two tests. But, like the ordinary class, there was some effect with the lapse of the third 2.9 for the test, 3.2 for the fourth and 4.1 for the fifth. 2. The Change of Mathematical Attitude 1) The Experimental Class The task learning by level had a great deal of effect on the experimental class, as the pre-and post-comparative analyses showed that this class's grades were 5.1 for self-confidence, 10.8 for flexibility, 11.3 for will power, 9.7 for curiosity, 10.9 for reaction and 2.8 for value. 2) The Comparative Class The relative comparison between the comparative class and experimental class revealed that there was a hole effect on the comparative class. 3. The Outcome of Questionnaire Survey 1) They showed a positive reaction, as 40.1% of them answered the level-based task loaming served to raise their achievement, and 48.0% told so-so, and 11.9% replied they weren't helped by it. 2) The results after the experiment were;37.8% of the students say they under- stood practically everything while 12.6% of them say they under stood almost half. 3) The will to learn after the experiment shows dramatic changes between the two classes, The students in the enrichment class showed better will to learn than the students in the ordinary and supplementary classes did.

"LeiGongPaoZhiLun" is the first pharmaceutical book, and there are various opinion on when LeiXiao(雷斅), the author lived. From the aspect of several data, it is appropriate most that LeiXiao live in the period of Sui(隋) Dynasty, like SuSong(蘇頌) in the Sung Dynasty said, This book was not made at one time by one person. At the beginning, it was written by LeiXiao and the later generations enlarged to finish. The original of "LeiGongPaoZhiLun" disappeared already but a large amount of this book was quoted to "ZhengLeiBenCao(證類本草)" to be preserved. The contents of "LeiGongPaoZhiLun" are the first professional book about processing of medicinal, in which most of processing of medicinal that is generally used today, is included and some methods are unused. Besides, the regulations of this book are specific, the range is broad, and theoretical frame is established for the first time. This book has abundant contents, in which several processing of medicinal are written. There are 10 methods such as steaming(蒸法), boiling(煮法), baking(炮法), stir-frying(炒法), calcining(煅法), long time boiling(煉法), scorching(燒法), baking after wrapping(煨法), immersing(浸法), washing(洗法), flying(飛法), etc. How to remove some section that is not used for drug, how to separate according to medical use and region to be applied, how to smash, how to cut, how to dry, container for medicine, warning for making a prescription, time to make medicine and amount of medicine, how to distinguish superior and inferior and origin, how to make medicine partially, etc, are contained in this book. The contents of "LeiGongPaoZhiLun" can be mixture of processing of medicinal of medical scientists and taoists. In conclusion, however, the effect by the later medical generations of "LeiGongPaoZhiLun" was not great on processing of medicinal. It stemmed from the difference of processing of medicinal in this very taoistic book that realistic difficulties were disregarded by taoists for training and practical purpose, treatment that is the reason that later medical generations used processing of medicinal. Consequently, there is no great relation between the development of processing of medicinal in the Sung Dynasty and this book. "LeiGongYaoXingFu(雷公藥性賦)" that was abundant in medical market in Ming(明) and Qing(清) period has no relation with "LeiGongPaoZhiLun" is kind of a distribution-purposed book that was mnge in or after Ming Dynasty. However, since a book that is said to be written by 'LiGao(李杲)'PaoZhihis nof a dijust borrowed and focus on a brief summery, it is not desirable for beginners to learn medical knowledge. "LeiGongPaoZhiLun" is the first pharmaceutical book and is a model to show how a science in the history of the herb medicine generated and developed and how such a book is changed and modified to make a change of value.

The purpose of this study was to investigate the perception and eating behaviors of middle school students in Kwangju area about food and nutrition section of Home Economics course. The subjects were 480 middle school students. The major results were as follows： On the perception f food and nutrition section, the 1st graders learned ‘how to settle the problems related to food and nutrition and food choices’. The 2nd graders learned ‘the knowledge and principle of food and nutrition for improving dietary life’. The 3rd graders learned ‘actual dietary life functions like arranging menu and preparing meals’. Consequently, there was a significant difference in each grade and all boy and girl students have the highest response to the item ‘they learn how to settle the nutrition problem and foods choices’. On the interests in food and nutrition section, lower graders and girl students have higher interest than hgiher graders and boy students. The area which was considered as most interesting in food and nutrition sections was ‘cooking’ in all students. The perception of the concern on dietary life after learning food and nutrition section was higher in the 1st graders. On the perception of the area where was a great change in their own dietary life after learning food and nutrition section, the 1st graders responded there was a great change in ‘balanced dietary life’, the 2nd graders in ‘eating habit and nutrition of adolescence’and the 3rd graders in ‘cooking’. Especially, girl students showed more changes. On the perception of degree which food and nutrition section gives a help to actual life, students over 50% responded that it was helpful to their actual life. This showed that the lower the grades, the more help it gave to those students. On the perception of mother’s job, the students with working mother considered that they learned ‘actual dietary life functions like functions like arranging menu and preparing meals’from the food and nutrition section. In addition, they had high interests in the area of ‘cooking’. It was recognized that as the family size was greater, the food and nutrition section gave more helps to actual life. On eating behaviors of breakfast, the higher the grade, the more frequent they don’t have breakfast, boy students have more frequencies of having breakfast than girl students and the primary reason of not having breakfast is poor appetite. On whether going without a meal affects study or not, most of the 1st, 2nd and 3rd graders whether they are boys and girls or not responded it affected their study. On eating behaviors of lunch, most of boy and girl students in the 1st, 2nd 3rd grade have lunch box. On eating behaviors of supper, eating time is usually between 7：00 and 8：00 p.m and eating hour is mostly 10 or 15 minutes. On eating behaviors between meals, frequency of eating between meals is mostly once or twice a day and girl students have more frequencies of eating between meals, and the cause was hunger commonly in boy and girl students and ‘killing time’in girl students. The focus in getting the foods is ‘taste’and favorite food is fruit regardless of the grade.

제 7차 컴퓨터교과 교육과정은 소프트웨어 활용 부분에 치중되어 컴퓨터과학에 관한 원리교육이 이루어지지 못하고 있다. 한편, ACM K-12 컴퓨터과학 교육과정 모델에 관한 보고서에서는 현재의 컴퓨터교육이 그릇된 방향이며 컴퓨터과학 중심의 컴퓨터교육을 위해서 프로그래밍언어 교육을 통한 원리교육의 중요성을 강조하고 있다. 본 논문에서는 프로그래밍 체험학습을 위한 객체지향 기반의 새로운 교육용프로그래밍언어인 두리틀(Dolittle)을 소개한다. 두리틀은 간결한 구문과 한국어와의 대응성, 인크리멘탈 방식의 프로그래밍, 수치, 문자열, 배열과 같은 알고리즘과 구조화, 텍스트 위주의 프로그래밍 등의 설계방침을 적용한 언어이다. 중학생을 대상으로 실제 수업에 적용해 보고 학습효과를 분석한 결과, 객체지향기반이지만 클래스나 상속 등의 개념을 모르고도 활용 가능한 교육용프로그래밍언어라는 것을 확인할 수 있었다. 또한 객체와 메소드 활용을 통하여 프로그래밍 결과를 쉽게 확인할 수 있고 오류 수정이 용이하므로, 학생들의 높은 흥미도를 유지하면서 학업성취도를 향상시키고 차후 학습으로의 연계가 수월하였다.

IEA's Third International Mathematics and Science Study(TIMSS) from 1994-1995 has placed Korea as one of the top three countries among 45 countries that participated in the study in mathematics achievement for the 3rd, 4th, 7th, and 8th grade students. While the test scores were excellent, the study also showed that mathematics education in Korea needed improvements in student attitudes, technology incorporation, and gender difference in achievement. An analysis of the a survey conducted as part of the mathematics curriculum research program showed that very little progress has been made in these areas for the past 5 years. Moreover, the progressively declining attitudes towards mathematics for high school students is a problematic phenomena for educators as we believe that mathematics is becoming even more important in an information technology based society. A comparison between the top three TIMSS scoring countries (Korea, Singapore, and Japan) and low scored country (U.S.) was made In this paper. We also compare some of problematic results from TIMSS to those from EERI Curriculum Study implemented in 2000. The study shows that simply using technology and improving student attitudes do not necessarily guarantee improved performance. Most of educators agree that potential for technology is great for both changing the way students learn and improving the attitudes of students. However, improperly implemented technology can hinder rather than help the educational process. Therefore, as we begin to implement and use more and moore technology, it is critical to develop the proper curriculum, training for teachers and research programs to track the progress and to make the necessary adjustments to provide the best possible education for our students. Another TIMSS result shows for all four grade levels(3rd, 4th, 7th, 8th), Korea shows the highest gender difference among all the participating countries. TIMSS data such as this is valuable to benchmark all types of information to get a better understanding about what is happening for improvements in math curriculum in Korea. More research needs to be done in comparing the performance of Korean mathematics education to understand both the strengths and weaknesses of our curriculum so that improvements can be made.

Nowadays, there are a great number of various structures that have been retrofitted by using different FRP Composites. Due to this, more researches need to be conducted to know more the characteristics of these structures, not only that but also a comparison among them before and after the retrofitting is needed. In this research, a model steel structure is tested using a bench-scale earthquake simulator on the shake table, using recorded micro tremor data, in order to get the dynamic behaviors. Beams of the model steel structure are then retrofitted by using CFRP composite, and then tested on the Quanser shake table by using the recorded micro tremor data. At this stage, it is needed to evaluate the dynamic behaviors of the retrofitted model steel structure. Various types of methods of OMA, such as EFDD, SSI, etc. are used to take action in the ambient responses. Having a purpose to learn more about the effects of FRP composite, experimental model analysis of both types (retrofitted and no-retrofitted models) is conducted to evaluate their dynamic behaviors. There is a provision of ambient excitation to the shake table by using recorded micro tremor ambient vibration data on ground level. Furthermore, the Enhanced Frequency Domain decomposition is used through output-only modal identification. At the end of this study, moderate correlation is obtained between mode shapes, periods and damping ratios. The aim of this research is to show and determine the effects of CFRP Composite implementation on structural responses of the model steel structure, in terms of changing its dynamical behaviors. The frequencies for model steel structure and the retrofitted model steel structure are shown to be 34.43% in average difference. Finally, it is shown that, in order to evaluate the period and rigidity of retrofitted structures, OMA might be used.
