본 연구는 예비보육교사가 보육실습이라는 과정에서 프로젝트 접근법에 대한 관심은 어떠하며, 관심변화 여부를 사례중심으로 살펴보는 것을 목적으로 하였다. 이를 위하여 예비보육교사를 대상으로 보육실습 사전과 사후검사를 실시하였으며, 자세하고 구체적인 사실과 연구의 질적인 부분을 찾아보고자 인터뷰하였다. 그 결과, 첫째, 프로젝트에 대한 예비보육교사들의 관심은 전반적으로 무관심으로 나타났다. 둘째, 사전․사후검사 결과, 프로젝트 접근법에 대한 관심수준의 변화가 있었던 사례에서는 관심변화의 패턴도 다양하게 나타났으며, 관심변화가 크게 없었던 사례에서는 개인, 정보관심이 높게 나타났다. 이러한 결과는 프로젝트에 대한 예비보육교사의 관심수준은 보육환경, 보육과정, 실습지도 교사, 예비보육교사의 지각력, 프로젝트에 대한 사전지식이나 교육정도에 따라 다양하게 변할 수 있음을 알게 되었다. The purpose of this study is to analyze the case in which we can identify how the SoC of prospective child care teachers about the project approach changes and why these change appears during the child care practice when we assumpt that for prospective child care teachers to implement the project approach is that they participate in change during child care practice. In Case K, the SoC of the prospective child care teacher moves from Stage 0 awareness to Stage 2, Stage 3, Stage 4, and In Case M, the SoC moves from Stage 0 to Stage 1. In Case P, the SoC moves from Stage 1 to Stage 2, Stage 3, and in Case S, the SoC isn't changed. Above this, we identify the SoC of prospective child care teachers. Case K, M, and P changes SoC after child care practice, but Case S doesn't change. the reason why there is a difference is the mindset of prospective child care teachers. Anyone who wants to accomplish specific purposes can deal with diverse changes with flexibility, but others can easily have an effect on the changes. We suggest that instructor in organization for prospective child care teachers’ education need to have a class for prospective child care teachers to put theory into practice, give direct facilitation and intervention in the field to prospective child care teachers, make a learning environment for prospective child care teachers to make good use of teaching materials and instrument, develop guidebook for project approach and give support to prospective child care teachers.

창의성 관점에서 본 제 7차 초등 수학과 교육과정 : 규칙성과 함수를 중심으로 Focusing on Patterns and Functions

서경혜,유솔아,정진영 한국수학교육학회 2003 初等 數學敎育 Vol.7 No.1

The present study examined the 7th national elementary school mathematics curriculum from a perspective of mathematical creativity. The study investigated to what extent the activities in the Pattern and Function lessons in the national elementary school mathematics textbooks promoted the development of mathematical creativity. The results indicated that the current elementary school mathematics curriculum was limited in many ways to promote the development of mathematical creativity. Regarding the activities in Pattern lessons, for example, most activities presented closed tasks involving finding and extending patterns. The lesson provided little opportunities to explore the relationships among various patterns, apply patterns to different situations, or create ones own patterns. In regard to the Function lessons, the majority of activities were about computing the rate. This showed that the function was taught from an operational perspective, not a relational perspective. It was unlikely that students would develop the basic understanding of function through the activities involving the computing the rate. Further, the lessons had students use exclusively the numbers in representing the function. Students were provided little opportunities to use various representation methods involving pictures or graphs, explore the strengths and limitations of various representation methods, or to choose more effective representation methods in particular contexts. In conclusion, the lesson activities in the current elementary school mathematics textbooks were unlikely to promote the development of mathematical creativity.

We previously reported that the SbROMT3syn recombinant protein catalyzes the production of the methylated resveratrol derivatives pinostilbene and pterostilbene by methylating substrate resveratrol in recombinant E. coli. To further study the production of stilbene compounds in E. coli by the expression of enzymes involved in stilbene biosynthesis, we isolated three stilbene synthase (STS) genes from rhubarb, peanut, and grape as well as two resveratrol O-methyltransferase (ROMT) genes from grape and sorghum. The ability of RpSTS to produce resveratrol in recombinant E. coli was compared with other AhSTS and VrSTS genes. Out of three STS, only AhSTS was able to produce resveratrol from p-coumaric acid. Thus, to improve the solubility of RpSTS, VrROMT, and SbROMT3 in E. coli, we synthesized the RpSTS, VrROMT and SbROMT3 genes following codon-optimization and expressed one or both genes together with the cinnamate/4-coumarate:coenzyme A ligase (CCL) gene from Streptomyces coelicolor. Our HPLC and LC-MS analyses showed that recombinant E. coli expressing both ScCCL and RpSTSsyn led to the production of resveratrol when p-coumaric acid was used as the precursor. In addition, incorporation of SbROMT3syn in recombinant E. coli cells produced resveratrol and its mono-methylated derivative, pinostilbene, as the major products from p-coumaric acid. However, very small amounts of pterostilbene were only detectable in the recombinant E. coli cells expressing the ScCCL, RpSTSsyn and SbROMT3syn genes. These results suggest that RpSTSsyn exhibits an enhanced enzyme activity to produce resveratrol and SbROMT3syn catalyzes the methylation of resveratrol to produce pinostilbene in E. coli cells.

The high quality Chinese Fuzhuan brick-tea grows mainly a yellow colored fungus, Eurotium sp. which is called as a golden flowering tea. It is known that Eurotium species are the sexual states of Aspergillus species. A few studies reveal that extracts from microbial fermented teas contain natural antimicrobial components that have inhibitive effect on several food-borne pathogen and spoilage bacteria. In this study, golden flowering teas were manufactured using inoculated a single fungus, E. cristatum, fermented and identified the microbes in the fermented teas by means of pyrosequencing. The microbial fermented tea, which grows yellow colored fungi was manufactured through 5-step processing such as mother-tea preparation, inoculation, fermentation, ripeness and desiccation. The manufacturing processes were already applied to nation patent (2014-0010502). In order to grouping the microbes and survey some contamination with harmful microbes, the pyrosequencing was performed on 8-samples manufactured different conditions. The result have shown that the phylum was Ascomycota 99.8%, the class was Eurotiomycetes 99.8% among total 27 class, the order was Eurotiales 99.6~99.8% among total 41 order, the family was Trichocomaceae 99.6~99.8% among 48 family, and the genus was Aspergillus 94.3~97.9% among 63 genus. The8-samples had 100% similarity in above 5-classification except genus level, otherwise the genus level have shown 94.3~97.9% of Aspergillus and 1.8~5.3% of Penicillium. The microbial fermented tea was manufactured successfully by single fungus inoculation. The pyrosequencing results indicate that the genus Aspergillus is existed dominantly in the tea which is the asexual name of Eurotium.

This study was accomplished to assess the body composition and the nutritional status of high school rhythmic gymnasts (RG. n=10) and nonathletic control group (NCG, n=10). Body composition was assessed through (1) body circumference, (2) skinfold thickeness, (3) percent of body fat by underwarer weighing, BIA and EDXA, and (4) regional fat of abdomen and thigh by CT. Nutrient intakes were determined from 24hr recall test and 2-day diet records. Data was analyzed by student`s t-test and Pearson`s correlation at p<0.05. Body circumference except chest did not differ significantly between the two groups. Skinfold thicknesses of triceps, suprailiac, mid-thigh and abdomen were thinner in RG compared with control (P<0.05 or p<0.001). Percent of body fat and regional fat of abdomen and thigh were lower in RG compared with NCG (p<0.05 or p<0.001). All nutrient intakes except iron and vitamin C were lower in RG compared with NCG (p<0.05 or p<0.001). Nonathletic control group had intakes less than 75% of RDA for calcium, iron, Vit. A, Vit. B_(1), and Vit. B_(2) and RG group for all nutrients except Vit. C. Body composition was correlated with several nutrient intakes, especially with animal fat intakem. Animal fat intake was positively correlated with skinfold thicknesses of triceps, abdomen, suprailiac and thigh, percent of body fat by underwater weighing, and subcutaneous abdominal fat, but not with body weight. In conclusion, there were significant differences in the body composition of the two groups despite of their similar body weight and BMI, which could be due to the differences in the nutrient intakes, especially in animal fat intake, of them. We suggest RGs should modulate themselves not body weight but body composition by adjusting animal fat intake, when they have to control weight for their competition.

Background/Aims: Colonoscopy is a painful procedure. Therefore conscious sedation is often used. However, the value of adding analgesics to sedatives has not been well evaluated. Methods: The double blind, randomized controlled trial was carried out to compare patients` and endoscopist` assessments in both groups of patients: MP (Midazolam/Placebo) group (n=49) received midazolam plus placebo and MM (Midazolam/Meperidine) group (n=51) received midazolam plus meperidine. Results: There was no significant difference of baseline characteristics except previous operation history. There were no significant difference of grade of tolerance, pain and willingness to another colonoscopy between the two groups. In endoscopist` satisfaction, the degree of difficulty was higher in MP group than in MM group (39.0 vs. 31.7, p<0.05). After the colonoscopy, systolic blood pressure, oxygen saturation, and pulse rate were significantly decreased (p<0.05) in both groups. However, there was no difference in the degree of decrease between the two groups. The incidence of adverse effect was not different in the two groups. However, one case of orthostatic hypotension with presyncope was noted in MM group. Conclusions: Adding meperidine to the midazolam before the colonoscopy does not seem to bring more beneficial effect to patients, whereas endoscopist favored the use of both medications.

Reactive dyeing wastewater, a toxic and refractory pollutant, was treated by an electrochemical method using Ti/IrO₂ as anode and Stainless Steel 316 as cathode. A number of experiments were carried out in a batch and continuous system. Artificial samples and samples from mill were used for the treatment. Operation parameters, such as electrode shape(net or plate), the content of free chlorine evolution, effect of electrolyte, the effect of supporting electrolyte concentration, current density, pH and electrode gab were investigated for their influences on COD and color removal efficiencies during electrolysis. Finally, a continuous system using wastewater sampled from mill was operated. Results show that important factors for the increase in the pollutants removal efficiency were electrical properties of the electrode, the kind and concentration of electrolyte, and current density. The result indicate that the electrochemical treatment method is effective for the removal of color and COD from reactive dyeing wastewater.
