본 연구에서는 유아의 연산 관련 표상유형의 특성을 분석하였다. 연구대상은 만 3세 37명, 만 4세 36명, 만 5세 37명, 만 6세 40명, 만 7세 35명의 총185명이었다. 연구기간은 10주 동안 유아 1인당 1~3회의 개별면접을 실시하였다. 연산 관련 표상유형의 분석은 예비연구 결과 나온 표상유형 범주에 의하여 면접 자료의 분류, 해석의 타당화가 이루어졌다. 그 결괴 유아의 연산 관련 표상유형은 자기만의 방식, 그림, 숫자, 수학기호, 언어로 표상하는 유형의 5가지로 나타났으며, 연령이 높아질수록 수학기호와 언어로 표상하는 유형이 증가하였다. To identify the types of representation of young children in arithmetical tasks, 185 children from 3 to 7 years old were interviewed individually one to three times per week for 10 weeks. The each individual interview was composed of arithmetic tasks, file-tasks, and words-tasks as well as in-depth interview after each task. The transcript of individual interviews was analyzed for the types of representation based on the categories from a preliminary study. Five types of representation such as idiosyncratic, pictorial, numerical, symbolic and written responses were observed in both addition and subtraction tasks. For addition tasks, idiosyncratic responses and pictorial responses were mostly used by 3 and 4 year old children, respectively. While pictorial and numeric responses were used mostly by 5 year old and symbolic response was used mostly by 6 and 7 year old children. For subtraction tasks, most 3 and 4 year old children used pictorial responses and most 5 year old children used pictorial and numeric responses as to symbolic responses by 6 and 7 year old children. In conclusion, all five types of representation, which are idiosyncratic, pictorial, numerical, symbolic and written responses, are used in both addition and subtraction tasks by young children. However, as they get older more symbolic and written responses are used for their arithmetic tasks.

최관우(Choi, Kwan-Woo),서성미(Seo, Sung-Mi),손순룡(Son, Soon-Yong) 한국산학기술학회 2014 한국산학기술학회논문지 Vol.15 No.8

조영제의 희석률 변화에 따른 신호강도를 분석하여 조영증강 자기공명혈관조영검사 시 점도와 삼투압에 따른 부작용 을 최소화하고 신호강도를 높여 영상의 질을 향상시키고자 하였다. 연구방법은 조영제가 혈관에 주입되면 혈액과 희석되어 mol 농도가 변화되고, 그에 따라 신호강도의 변화를 일으킴에 착안하여 phantom을 제작하였다. phantom 결과를 바탕으로 임상실험은 2013년 11월부터 2014년 1월까지 조영제를 희석한 군(30명)과 희석하지 않은 군(30명)으로 구분하여 뇌혈관의 신호강도를 비교하였다. 연구결과, 조영제 mol 농도 변화에 따른 phantom의 신호강도는 0.0125mmol부터 급격히 증가하다 20mmol에서 최고점을 이룬 후 200mmol부터 평형을 이루었다. 임상실험에서도 조영제를 희석하여 검사한 영상의 신호강도 가 모두 높게 나타나, 1000mmol 조영제 사용에 비해 500mmol로 희석하여 사용함이 최고점인 20mmol에 근접하여 우수함을 알 수 있었다. 결론적으로 조영제를 희석하여 사용함으로써 점도와 삼투압을 저하시키고, 영상의 질을 향상시킬 수 있었으므 로 임상적용의 유용성이 높다고 할 수 있다. Dilution of the contrast agent by analyzing the change in the signal intensity during MR angiography in accordance with the viscosity and osmotic pressure minimizes the side effects, and improves the image quality. The contrast agent molarity changes by the dilution of the contrast agent in the blood, as it is injected, which leads to a change in signal intensity. Based on this principle, a phantom was prepared and experiments were performed. After the phantom experiment, a clinical experiment was conducted using the results of the phantom experiment. From November 2013 to January 2014, a group of patients were classified into diluted contrast agent (30 persons) and undiluted (30 persons), and the signal intensity of the cerebral vessels was compared. The signal intensity of the phantom according to the molarity of the contrast agent increased sharply from 0.0125 mmol, reached a peak at 20 mmol, and achieved equilibrium from 200 mmol. Based on the study results, the signal intensity of the blood vessels in the brain through were compared in a clinical experiment. All the brain vessels in the imaging range with diluting a high content of the gadolinium contrast agent showed high signal intensity. This result supports the phantom experiment and means that using the 500mmol diluted contrast agent is better than using 1000mmol undiluted contrast agent because it is easier to approach the 20mmol level needed to achieve the highest signal intensity. This study has significance in that it can minimize the high viscosity and osmotic pressure, which can cause side effects and improve the image quality using the method of the dilution rate.
