미국 Common Core State Standards for Mathematics 소개

김영옥,Kim, Young-Ok 영남수학회 2011 East Asian mathematical journal Vol.27 No.4

The purpose of this study is to introduce the Common Core State Standards (CCSS) for mathematics which is released on June 2, 2010 in the U.S.A. The common core state standards are aligned with college and work expectations, and include rigorous content and application of knowledge through high-order skills. The most distinguishable differences between the CCSS standards and the NCTM standards are that the CCSS standards considers the mathematical modeling as one of the mathematical content domains such as algebra, geometry, ets, and the standards are designed by working together with school leaders of all states.

Anticonvulsant hypersensitivity syndrome is a rare but fatal complication. It manifests as fever, skin rash, lymphadenopathy, and hepatitis. Phenytoin, phenobarbital, and carbamazepine are the most frequently involved drugs. We here report a case of phenytoin-induced anticonvulsant hypersensitivity syndrome. A 37-year-old woman presented with fever and generalized skin rash, 3 weeks following commencement of phenytoin 400mg daily for treatment of seizure after superficial temporal artery-middle cerebral artery(STA-MCA) anastomosis for moyamoya disease. Her temperature was $39.3^{\circ}C$ and her face was edematous. Laboratory findings showed elevated hepatic enzymes and eosinophilia. Blood and urine culture were all negative. Initially, prednisolone was commenced at 30 mg daily. But fever and skin rash did not improved and hepatic function was more aggravated. After increasing dose of steroid(methylprednisolone 125mg/day), fever and skin rash disappeared and hepatic enzymes returned to normal range.

Purpose : The survival rate of very low birth weight infants(VLBWI) has improved by virtue of specialized neonatal care. This study was performed to analyze the changes in incidence, survival rate and morbidity of VLBWI who admitted to Chonnam National University Hospital from 1996 to 2001. Methods : We enrolled 565 VLBWI, and compared the incidence and the survival rate according to the birth weight or gestational weeks between period I(1996 to 1998) and period II(1999 to 2001). The mortality rate according to the postnatal age, cause of death, morbidity and days of hospital stay were also compared. Morbidity is categorized into 'short term' which is curable until discharge, and 'long term' causing any types of sequelae after discharge. Results : Incidence of VLBWI significantly increased in period II over period I(6.0% vs. 11.0%, P< 0.001). The survival rate also increased in period II(71.8% vs. 80.1%, P<0.05), especially in 1,000 to 1,249 gm of birth weight(P<0.001) and in 28 to 30 weeks of gestation(P<0.001). The most common cause of death was respiratory distress syndrome in period I; however it was sepsis in period II. Although overall and short term morbidity rate increased, long term morbidity and days of hospital stay didn't increase in period II. Conclusion : Although the incidence of VLBWI significantly increased and the survival improved in period II compared to period I, especially in 1,000 to 1,249 gm of birth weight and 28 to 30 weeks of gestation, 'long term' morbidity rate and hospital days didn't increase.

This study was to analyze the research trend related to mathematics education evaluation in the analysis of the articles on <National mathematics education journal>, <Korea mathematics education journal>. The study explores the future direction of mathematics education assessment research by investigating whether such evaluation was suitable for the expectation about the assessment required in the current mathematics curriculum. This study was to classify the evaluation-related researches based on Korea educational curriculum revision from 1991-2010 to examine the research trend on the mathematics education evaluation in each season in Korea, analyze the articles by 'monitoring of student's progress', 'judgement on instruction', 'giving the value on mathematics achievement of students', 'value judgement of the program' that were the purpose of evaluation presented in 1995 NCTM(National Council of Teachers of Mathematics). As a result, looking at the research trend classified by the time of the educational curriculum revision, the 7th educational curriculum had the most number of the papers announced from 1997-2006. Despite 2007 educational curriculum revision was the short period from announced 2007-2008 before the next educational curriculum was placed, 11 papers(34.4%) were published. According to the category by the purpose of the assessment prescribed in NCTM, it showed that researches of 'monitoring of student's progress(46.9%)' were the most, those of 'value judgement of the program' and 'giving the value on mathematics achievement of students had a similar percentage.

Marine planktonic ciliates include two major groups, loricated tintinnids and naked oligotrichs. The study of marine ciliate plankton in Korea began with taxonomic efforts on tintinnids based on the morphology of lorica, a vase-shaped shell. Despite polymorphism in the lorica, it is utilized as a key characteristic in identification of tintinnid species. However, oligotrichs have been studied only recently in Korea due to challenges associated with the observation of ciliary arrangements and the technical development for cell staining. Species diversity and phylogenetic classification of the ciliates have been informed by recent advances in morphological and molecular analyses. Illustrations of the planktonic ciliate in Korea have been published on the basis of taxonomic data of tintinnids and oligotrichs. Planktonic ciliates acting as the major consumers of pico- and nanoplankton as well as the prey of mesozooplankton, has been monitored by spatial and temporal investigations in Korean coastal waters. A practical approach addressing the limitations and potential of marine ciliate studies in Korea is proposed here to improve the data quality of planktonic ciliates, providing an enhanced basis for quality control of ciliate monitoring.

Isotropic pitch based carbon fibers have been activated at different levels of burn-off by steam diluted in nitrogen. There is a slight uptake of CO₂ at 273 K indicating that some microporosity is already present in the unactivated fiber. These micropores are, however, unaccessible to N₂ at 77 K. The specific surface area and the micropore volume of carbon fiber were increased significantly upon activation, however after 60% burn-off, the micropore volume measured by D-R equation levels off where as the one determined by the as-method steadily increase with the extent of activation. The adsorption of iodine and the decolorization of methylene blue of activated carbon fiber from aqueous solution were excellent, especially adsorption rate was greatly fast. The adsorption capacity was enhanced with the burn-off increasing, but it was also dependent on micropore size distribution.

Trisomy 9 mosaic syndrome is a rarely reported chromosomal abnormality with high incidence of intrauterine growth retardation and perinatal death. Even a baby lives, he has severe mental retardation and significant malformations. The incidence and severity of malformations and mental retardation correlate with the percentage of trisomic cells in the different tissues. The characteristic craniofacial abnormalitis are narrow bifrontal diameter, up-slanted and short palpebral fissures, a prominent nasal bridge with a short root, a prominent lip covering a receding lower lip, low-set, posteriorly rotated, and misshapen ears. Ventricular septal defect is a main cardiac abnormality. Bony hypoplasia and dislocated hips have been frequently reported. Central nervous system, hepatobiliary, gastrointestinal and genitourinary abnormalities also had been reported. The authors report a baby who had characteristic abnormalities of trisomy 9 mosaicism with narrow temples, up-slanted palpebral fissures, a bulbous nose, thin and protruding upper lip, low set and malformed ears, hyperextended wrist and overlapping fingers. Cytogenetic analysis performed to confirm the chromosomal abnormality revealed trisomy 9, low level mosaic type.

Eccrine acrospiroma is a rare adnexal tumor of the skin. When the clinical presentation is that of a breast lump, diagnosis can be difficult. Also, most of the cytopathologists are not familial with the cytologic features of this tumor and this is responsible for diagnostic pitfalls. We experienced a case of eccrine acrospiroma of the right breast in a 41-year-old female, misdiagnosed by fine needle aspiration cytology (FNAC). FNAC was characterized by tight clusters or sheets of small round cells, polygonal cells, and spindle cells and tubule like structures within clusters. Myoepithelial cells were not noted in the clusters. The diagnosis of eccrine acrospiroma was confirmed by histology.

We isolated a marine bacterium, Pseudomonas sp,, which could produce the enzyme of alginate lyase, and cloned the alginate lyase gene in Escherichia coli. The cloned DNA was overexpressed with approximately $50\%$ amount of total proteins. In addition, the expressed proteins were not secreted into the medium, and most of them existed in the cytoplasm by the soluble form, but not observed any inclusion body by TIM. For the optimum enzyme activity, temperature was $20^{\circ}C$, pH was 7.0, and Km and Vmax values of the enzyme were $0.4\%$ and 625 units/mg, respectively.

The effect of carbohydrates, fat and protein consumption on the blood pressure of adolescents was investigated from the cross sectional data. The two major areas of inquiry were : 1)measuring the variation of blood pressure at various levels of macronutient intake. 2)measuring the relative importance between the factor of nutrient intake and physical growth. A total of 726 students(341 boys and 385 girls) in the first grade of middle school in Kangwha country were studied for their dietary consumption and physical growth as well as blood pressure. Multiple regression analysis was used as the analytical method to identify the relative importance between the factors. Besides the macronutrient consumption, other nutrients such as vitamin and mineral intakes were included in the regression model. The results showed a variation of blood pressure by macronutrient intake level was in consistant both in blood pressure and by gender. Systolic and diastolic blood pressure decreased with increasing protein intake for girls(p<0.05). However, it was not observed in the case of boys. The systolic blood pressure of boys showed a tendency to decrease with fat intake increase, while their diastolic blood pressure showed the opposite trend. Results of the regression analysis showed that physical growth was a more influential factor than nutrition on blood pressure for both sexes. This could imply that the dietary hypertension factors observed in adults may not be operative generally in a population with normotensive blood pressure during growth.
