Communicating about mathematics is an essential component in learning mathematics and is a key standard for successful learning in a mathematics classroom using stories and storytelling as a catalyst to mathematics instruction. This, however, can make learn-ing math for students with language deficiencies since they are working toward master-ing both basic language proficiency as well as the specialized language needed for math-ematics. This is a particular concern because the number of students of multicultural families is rapidly increasing. In this paper, we discuss the challenges and complexities of language-deficient students learning math in a classroom where communication is a key standard for successful learning, and suggest implications for teaching, by presenting an USA elementary teacher`s scaffolding to make reading and solving word problems less intimidating for her language learner students as well as native speaking students.

본 연구는 초등 예비교사의 교사지식 중 분수 나눗셈 스토리 문제 제기(problem posing) 수행 정도를 파악하고자 하였다. 나눗셈에 관한 스토리 문제 제기 능력은 나눗셈의 개념을 실생활 맥락에서 유연하게 사용하는 능력과도 관련이 있기 때문에 초등 예비교사들이 향후 교실에서 실생활 소재를 통해 나눗셈 교수 내용을 구성하고 가르치는데 있어 중요한 능력이라 할 수 있다. 이를 위하여 초등 예비교사 135명을 대상으로 자연수 나누기 분수 문제에 대한 설문조사를 실시하고, 분석틀 기준에 따라 ‘수학적정교성’과 ‘주요 오류 유형’ 그리고 ‘나눗셈 연산 모델’의 세 부분으로 나누어 자료를 분석함에 따라 초등 예비교사의 나눗셈 교사 지식에 대한 시사점을 제공하였다. This study examined pre-service teachers`` pedagogical content knowledge of fraction division in a context where they were asked to write a story problem for a symbolic expression illustrating a whole number divided by a proper fraction. Problem-posing is an important instructional strategy with the potential to create meaningful contexts for learning mathematical concepts, especially when real-world applications are intended. In this study, story problems written by 135 elementary pre-service teachers were analyzed with respect to mathematical correctness. error types, and division models. Patterns and tendencies in elementary pre-service teachers`` knowledge of fraction division were identified. Implicaitons for teaching and teacher education are discussed.

Dietary patterns are associated with physical growth among school girls aged 9-11 years

Noh, Hwa-Young,Song, Yoon-Ju,Lee, Jung-Eun,Joung, Hyo-Jee,Park, Min-Kyung,Li, Shan Ji,Paik, Hee-Young The Korean Nutrition Society 2011 Nutrition Research and Practice Vol. No.

The purpose of this study was to identify dietary patterns among Korean elementary school girls based on the change in body mass index (BMI), body fat, bone mineral density (BMD), and bone mineral content (BMC) during 22 months and to explore the characteristics of dietary patterns identified. Girls aged 9-11 years were recruited and 3-day dietary data were collected four times. Subjects with a diet record of 8 or more days and anthropometric data measured at baseline and 22 months later were included (n = 198). Reduced rank regression was utilized to derive dietary patterns using a change in BMI, body fat, and calcaneus BMD and BMC as response variables. Two dietary patterns were identified: the "Egg and Rice" dietary pattern and "Fruit, Nuts, Milk Beverage, Egg, Grain" (FNMBEG) dietary pattern. Subjects who had high score on the FNMBEG pattern consumed various food groups, including fruits, nuts and seeds, and dairy products, whereas subjects in the "Egg and Rice' dietary pattern group did not. Both dietary patterns showed a positive association with change in BMI and body fat. However, subjects who had a higher score on the "Egg and Rice" dietary pattern had less of a BMC increase, whereas subjects who had a higher score on the FMBEG dietary pattern had more increased BMC over 22 months after adjusting for age, body and bone mass, and Tanner stage at baseline. Our results provide evidence that a well-balanced diet contributes to lean body mass growth among young girls.

본 연구의 목적은 한반도 남부 지역에서의 지진동 감쇄식을 개발하는 것이다 활용가능한 계기 지진 자료로부터 지진원 및 지반 매질의 특성을 추정하고 그 값을 입력 요소로써 사용하였다 확률진동이론에 의하여 최대 지반가속도 및 의사 속도 응답스펙트럼을 모사하여 이로부터 최대지반 가속도 및 의사 속도 응답스펙트럼에 대한 감쇄식을 지역규모 및 진원거리의 함수로 개발하였다 The objective of the study is to develop attenuation equations of the ground motions in the southern part of the Korean peninsula. The earthquake source characteristics and the medium properties were estimated from available instrumental earthquake records and used as input parameters. The peak ground accelerations(PGA) and pseudo-velocity response spectra(PSV) were simulated by the random vibration theory. The attenuation equations for the PGA and PSV were constructed in terms of local magnitudes and hypocentral distances.

Vegetable-based diets have generally focused on their health benefits including negative associations with the serum cholesterol concentrations. The aim of this study was to investigate whether serum lipid concentrations are influenced by the amount of kimchi intake. For the study, 100 volunteers were assigned to 2 dietary groups, low (15g/day, n=50) and high (210g/day, n=50) kimchi intake, and were housed together in a dormitory for 7 days. Identical meals except with different amount of kimchi were provided and subjects were instructed to maintain their normal physical activity. Concentrations of fasting blood glucose (FBG), total glucose, total cholesterol and low density lipoprotein (LDL)-C significantly decreased in both groups after 7 days of kimchi intake, but the effects were dose dependent. Lipid lowering effects of kimchi were more profound in the subjects with total cholesterol and LDL-C level over 190 and 130mg/dL, respectively, in both groups. FBG was significantly decreased in the high kimchi intake as compared to the low intake group (P=.003). In conclusion, greater consumption of kimchi improved FBG and serum total cholesterol in young healthy adults.

Congenital cysts of the gallbladder are extremely rare, hence only a few ciliated foregut cysts of gallbladder have been reported.We report a case of a 20-year-old woman presenting with mild right upper quadrant abdominal discomfort, with normal levels of serum bilirubin and liver function tests. Abdominal ultrasonography revealed a well-defined cystic mass measured about 2 cm attached to the neck of gallbladder, with internal echogenic debris suggesting a complicated cyst, such as a hemorrhagic cyst. Abdominal computed tomography and magnetic resonance cholangiopancreatography revealed similar findings.Laparoscopic cholecystectomy showed a slightly distended gallbladder. The size of cyst on the neck was 1.6×1.2 cm, and it contained mucosa lined by ciliated pseudostratified columnar epithelium and underlying smooth muscle layers. Histopathology identified a ciliated foregut cyst of gallbladder.(Korean J Gastroenterol 2016;67:49-53)

Loss-of-function mutations in the Transcription Factor 7 (T cell factor-1) gene in hepatogastrointestinal cancers

Inappropriate activation of the Wnt signaling pathway has been repeatedly implicated in the tumorigenesis of colon, liver, and gastric cancers. There is accumulating evidences that transcriptional factor 7 (TCF7; also called T cell factor 1) might also be one of the tumor suppressor genes in the Wnt pathway. We performed PCR-based sequencing analysis of the TCF7 gene in 234 alimentary tract cancers. The TCF7 mutants detected in this study were functionally analyzed after they were generated by a QuickChange site-directed mutagenesis kit. We detected 7 somatic mutations in the TCF7 gene, including 4 missense, 2 frameshift, and one 28-bp deletion. In a yeast two-hybrid assay, most of the mutants showed varying degrees of decreased binding to an amino-terminal enhancer of split (ABS), a truncated form of Groucho-related protein lacking WD40 repeats. To determine whether mutant TCF7 proteins had decreased DNA binding, we performed electrophoretic mobility shift assays, and the 2 frameshift mutants were shown to have no DNA binding activity. Furthermore, luciferase reporter assays revealed that TCF7 mutants in the presence of AES failed in the AES-dependent transcriptional repression of the reporter gene. In addition, human embryonic kidney 293 cells transfected with TCF7 mutants expressed high levels of cyclin D1, up to 6 times more than cells transfected with wild-type TCF7. Therefore, the TCF7 mutations detected in this study seem to be "loss-of-function mutations" caused y loss of TCF7 repressor activity through decreased binding to Groucho-related protein and/or DNA, thereby contributing to neoplastic transformation by causing accumulation of cylin D1.
