수학영재학급 학생들과 일반학급 학생들의 통계적 사고 수준 비교 연구 : 변이성 모델링과 표집분포 이해 능력 중심으로

고은성 韓國英才學會 2012 영재교육연구 Vol.22 No.3

본 연구에서는 통계적 모델링과 표집분포 이해 능력을 중심으로 수학영재학생들과 일반학생들의 통계적 사고 수준을 비교한다. 연구결과 통계적 모델링에 대한 사고 수준에서 초등학교 수학영재학생들과 일반학생들, 그리고 중학교 수학영재학생들과 일반학생들 사이에 통계적으로 유의한 차이가 있는 것으로 나타났다. 그리고 표집분포의 이해에 대한 사고 수준에서 초등학교 수학영재학생들과 일반학생들 사이에서 통계적으로 유의한 차이가 있는 것으로 나타난 반면, 중학교 수학영재학생들과 일반학생들 사이에서는 통계적으로 유의한 차이가 나타나지 않았다. 그러나 수준별 빈도를 조사한 결과 수학영재학생들의 사고 수준이 상위 수준에 집약되어 분포하기보다는 일반학생들의 사고 수준이 상당부분 중첩되어 있는 것으로 나타났다. 이러한 연구결과는 수학영재학생들에게 통계를 지도하는 데 있어 유용한 시사점을 제공한다. This study compared levels of mathematically talented students' statistical thinking with those of non-talented students in statistical modeling and sampling distribution understanding. t tests were conducted to test for statistically significant differences between mathematically gifted students and non-gifted students. In case of statistical modeling, for both of elementary and middle school graders, the t test show that there is a statistically significant difference between mathematically gifted students and non-gifted students. Table of frequencies of each level, however, shows that levels of mathematically gifted students' thinking were not distributed at the high levels but were overlapped with those of non-gifted students. a similar tendency is also present in sampling distribution understanding. These results are thought-provoking results in statistics instruction for mathematically talented students.

The purposes of this study were to investigate species of attached algae, and determine these characteristics and relations of odor origin for estimating its source in tap water. Oscillatoria sp. and Mougeotia sp. were colonized at the upper and lower of sedimentation basin in water treatment plant, respectively. In the results that they were analysed to collect colonies of Oscillatoria sp. and Mougeotia sp, they did not detected inodorous Mougeotia sp. but Oscillatoria sp. of some decayed odor did geosmin 3.7ppt and Dimethyl-disulfide with trace. 20species compounds were found in each of sample that were incubated in room temperature for 5days, 4species of these were THMs originated tap water and concentration was 35㎍/ℓ, and 16species compounds were by algac. Especially, sulfur compounds of 10species such as Dimethyl-sulfide were initially not detected but did very much. Also, Indole and Naphthalene were small detected. Considering characteristics of decayed decomposed sampling, generated byproduct for decayed algae of 2species turned out to be nearly identical. If estimating course of odor generation in tap water, chlorine tolerative algae formed big colony to be attached in sedimentation basin and decay was advanced with varying anaerobic condition inside colony's algae. Therfore, a lump of algae detached in suspended state flowed in filter bed, and owing to decayed colony's algae, generated inodororus material could inflowed tap water.

The purpose of this study was to investigate psychological factors, including anxiety, depression, self-esteem, well-being. Eighty-nine subjects of this study were 60years of age or over and living either in institution or in the community. The data were collected from July 30, 2001 to October 20, 2001 by using structured questionnaire. The instruments were MSQ(Mental Status Questionnaire), the Self Rating Anxiety Scale for Anxiety(Zung, 1967), GDSK(Geriatric Depression Scale-Short Form, Korean Version, Brink, 1982 ; Chojuyeon, 1999), Self-Esteem Scale(Rosenberg, 1965) for Self-esteem, and Affect Balance Scale(Bradburn, 1969) for well-being which is a psychological measurement instrument. The data were analysed by SPSS WIN 10.0. using frequency, x2-test, t-test, and pearson's correlation coefficient. The findings of this study are as follows; 1. Anxiety was higher in the home-dwelling older people(40.83±9.29) than institutionalized older people(33.03±10.81) and there was statistically significant difference(t=-4.89, p<0.001). 2. Depression was lower in the home-dwelling older people(6.74±3.29) than institutionalized older people(7.41±3.16), but there was not statistically significant difference. 3. Self-esteem was higher in the home-dwelling older people(27.71±4.32) than institutionalized older people(26.56±6.28), but there was not statistically significant difference. 4. Well-being was higher in the home-dwelling older people(5.97±2.38) than institutionalized older people(5.08±2.46), and there was statistically significant difference(t=-2.271, p<0.05). 5. The correlations between psychological factors in institutionalized and home-dwelling older people were found. Anxiety was positively correlated(r=0.374, p<0.01) with depression and negatively correlated with self-esteem(r=-0.296, p<0.01) and well-being(r=-0.287, p<0.01). Depression was negatively correlated in self-esteem(r=-0.448, p<0.01) and well-being(r=-0.500, p<0.01). There was positive correlation between self-esteem and well-being(r=0.498, p<0.01).

은성수,이수용 한국항공대학교 1998 論文集 Vol.36 No.-

온도하중이 작용할 때 복합재료 하니콤 샌드위치 쉘 구조물의 거동을 파악하기 위해서 3차원 응축쉘 이론 그리고 일차전단 변형이론에 입각한 유한요소 해석이 수행되었다. 본 연구에서는 하니콤을 탄성보강재로 가정하여 온도가 증가함에 따라 하니콤과 적층쉘 사이에서 발생하는 분리현상을 규명하였다. 이러한 파손현상은 적층각도와 적층쉘 두께이 따라 다르게 나타났다. 준등방성 그리고 직교이방성 보다도 angle-ply 적층순서에서 파손이 많이 발생하였고 또한 적층쉘의 두께가 증가함에 따라 파손현상이 많이 발생하였다. Finite element analysis based on 3-D degenerated shell theory and first shear deformation theory was peformed to investigate the behavior of composite and honeycomb sandwich shell structures under thermal loading. In this study, the honeycomb was regarded as an elastic foundation and delamination phenomenon occurring between the laminated shell and the honeycomb was examined as temperature increases. The results shows that the delamination depends on lay-up angle and thickness in the composite shell. A lot of failure was occurred for angle-ply stacking sequence rather than for quasi-isotropic and cross-ply stacking sequences and a lot of failure was occurred as the thickness of the composite shell increases.

Robust camera parameters estimation

김태은,김상훈 남서울대학교 2009 남서울대학교 논문집 Vol.15 No.2

In this paper, we propose a new camera calibration method for the 3D-based image synthesis and 3D reconstruction. We improve the problem as changing the principle point for obtaining the linear equation. According to the error rate, we adapt the non-linear method that minimizes the intrinsic parameters. Namely, it minimizes the intrinsic parameters error with maintaining the computational conciseness. As a result, we can find optimized camera intrinsic parameters and adapt to image synthesis and reconstruction. Keywords : Camera Calibration, 3D-based image synthesis, 3D Reconstruction. 본 논문에서는, 우리는 synthesis이미지를 이용한 새로운 카메라 캘리브레이션 측정 방법을 제시한다. 우리는 선형 방정식을 얻기위한 기본적인 포인터를 바꾸기로 개선한다. 오류율에 따르면, 우리는 본질적인 매개변수를 극소화하는 비선형 방법을 적용하였다. 그것은 컴퓨터 간결함 유지를 가진 본질적인 매개변수 과실을 극소화한다. 그 결과로, 우리는 예상한 사진기 가장중요한 매개변수를 찾아내고 3D재구성에 적용이 가능하였다.
