The purpose of this study was to investigate the relation between the cognitive processes and the mathematical achievement of the 4th grade students. And according to the several studies, there were significant relation between cognitive processes and achievement. Based on the PASS(Planning-Attention-Simultaneous-Successive Processes) Model presented by Das and Naglieri, four cognitive process variables were selected. The results of this study as follows. First, there was not significant relation between attention and mathematical achievement. Second, there was significant relation between planning and mathematical achievement. Third, there was significant relation between simultaneous/successive processes and mathematical achievement. Fourth, the students who got higher scores in the two types (simultaneous/successive)of information processing had more mathematical achievement. Specially, the students who got higher scores in the type of simultaneous information processing had higher scores in mathematical achievement. These results indicated that planning and simultaneous information processing had influence on the mathematical achievement.

The purpose of this study was to examine the effects of young children's age and information processing style in understanding spatial coordinates. For sampling the subjects of this study, Korean version K-ABC Intelligence Test(Moon, Soo-Back, 1997)was conducted with 165 children aged 5-6 who were attending I and G kindergarten in D city. From this pool 30 children who possessed sequential processing style and 30 children who possessed simultaneous processing style were sampled. In order to analyze the understanding of spatial coordinates, a test tool was formulated according to methodology of Blades & Spencer(1989) which was modified. Acquired data was subjected to descriptive and comparative statistical analysis. The following conclusions were arrived at: Firstly, there was significant difference between 5-year-olds and 6-year-olds in understanding spatial coordinates. The 6-year-old group got statistically higher grades than the 5-year-old group in locating a point on the coordinate plane and reading the coordinate numbers. Secondly, there was significant difference between children's information processing style in understanding spatial coordinate. Children with high simultaneous-low sequential processing showed higher performance in locating a point on the coordinate plane and reading coordinate numbers than children with high sequential-low simultaneous processing. Thirdly, after verifying statistical significance of interactivity between young children's age and children's processing strength, there was significant interactive effects in both tasks.

We present the simultaneous growth of single-walled carbon nanotubes and graphene with the optimal conditions of the synthesizing parameters. The dense and vertically aligned SWNTs having the length of over 100 ㎛ was grown by 2 nm-thick Fe catalytic layer. From 650 ℃, the vertically well-grown SWNTs were obtained by increasing the temperature. The severallayered graphene was synthesized with the gas mixing ratio of 15 : 1(H2 : C2H2) at 650 ℃ and higher temperatures. With these optimal conditions, the vertically well-grown SWNTs and the several-layered graphene were synthesized simultaneously. The presence of SWNTs and the layer of graphene were verified by field emission scanning electron microscopy and high resolution transmission electron microscopy. From the result of this simultaneous synthesizing approach, the possibility of one step growth process of CNTs and grapheme could be verified.

The purpose of this study was to identify the relationships between children's information processing style and creativity. The subjects were 40 5-year-old kindergarten students in Busan. The K-ABC (Kaufman Assessment Battery for Children, 1987) test and Torrance's TTCT were used to examine the relationships between children's information processing style and creativity. This analysis showed no significant correlation between information processing style and creativity. On the other hand, the sequential processing style affected fluency and the simultaneous processing style affected originality, elaboration, and abstractness of titles.

본 연구는 유아의 정보처리능력인 동시처리 및 순차처리능력과 기초학습능력이 어떠한 관계가 있는지, 그리고 읽기, 쓰기, 기초수학을 포함하는 기초학습능력에 대한 정보처리능력의 상대적 설명력이 어떠한지를 알아보고자 하였다. 취학직전 만 5~6세 유아 99명을 대상으로 유아그림기초학습능력검사와 K-ABC 검사를 실시하여 기초학습능력과 정보처리능력을 측정하였다. 본 연구결과로써 첫째, 유아의 정보처리능력과 기초학습능력 간 상관을 살펴본 결과, 유아의 순차처리능력과 기초학습능력 간, 동시처리능력과 기초학습능력 간 유의미한 정적 상관이 있는 것으로 나타났다. 각 하위영역인 읽기, 쓰기, 기초수학 능력과 동시처리 및 순차처리능력 간에도 유의미한 정적 상관이 있는 것으로 나타났다. 둘째, 유아의 기초학습능력에 대한 정보처리능력의 상대적 설명력을 알아본 결과, 유아의 정보처리능력 중 동시처리능력이 기초학습능력에 22%의 설명력을 가지며, 여기에 순차처리능력이 첨가됨으로써 설명력이 3% 증가하여 25%의 설명력을 가지는 것으로 나타났다.

The purpose of this study was to examine the feasibility of validating the Kaufman Assessment Battery for Children(K-ABC) with Korean preschoolers. Subjects were 197 preschoolers of 3,4 and 5 years of age. The mean of the MPC(Mental Processing Composite) scores was 111.7 and SD was 12.26. According to the item discriminant method, most subtests of Sequential Processing and the triangle subtest of Simultaneous Processing were significant, but the other subtests were insignificant. All subtests were highly correlated with MPC, and both the Sequential Processing Scale and Simultaneous Processing Scale were highly correlated with MPC; but the correlation between the two scales was low. Internal consistency was satisfactory on both scales(Cronbach' ${\alpha}$=.76 -.86). A further study is needed to diminish cultural discriminants and to include more samples from diverse subject groups.

The synthesis of pure calcium carbonate nanocrystals was achieved using a simultaneous injection method to produce nano particles of uniform size. These were characterized using scanning electron microscopy and powder X-ray diffraction. The nano particles were needle-shaped aragonite polymorphs, approximately 100-200 nm in length. The aragonite polymorph of calcium carbonate was prepared using aqueous solutions of $CaCl_2$ and $Na_2CO_3$, which were injected simultaneously into double distilled water at $50^{\circ}C$ and then allowed to react for 1.5 h. The resulting whisker-type nano aragonite with high aspect ratio (30) is biocompatible and potentially suitable for applications in light weight plastics, as well as in the medical, pharmaceutical, cosmetic and paint industries.

The feature of resolution enhancement by derivative operation is linked to one of the multivariate analysis, which is multiple linear regression with two options, all possible and stepwise regression. Examined samples were synthetic mixtures of 5 vitamins, thiamine mononitrate, riboflavin phosphate, nicotinamide, pyridoxine hydrochloride and ascorbic acid. All components in mixture were quantified with reasonably good accuracy and precision. Whole data processing procedure was accomplished on-line by the development of three computer programs written in APPLESOFT BASIC language.

시계열반전처리는 시간과 공간영역 동시에 집속을 수행할 수 있는 효과적인 방법으로 증명되어 왔으며, 시간영역에서의 집속 특성은 수중음향통신에서 광범위하게 이용되고 있다. 최근에는 해양도파관에서 동시 다중 집속이 적응 시계열 반전처리에 의해 구현되었다. 본 연구에서 적응 시계열반전처리에 의한 동시 다중 집속은 다중 수신을 위한 수중음향 통신 알고리즘으로 확장되며, 개발된 알고리즘은 수치실험과 실 데이터를 통해 다중 수신 위치에 동시에 자기등화가 가능함을 보였다.
