  • 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.

  • 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.

  • The performance issues of screening large database compounds and multiple query compounds in virtual screening highlight a common concern in Chemoinformatics applications. This study investigates these problems by choosing group fusion as a pilot model and presents efficient parallel solutions in parallel platforms, specifically, the multi-core architecture of CPU and many-core architecture of graphical processing unit (GPU). A study of sequential group fusion and a proposed design of parallel CUDA group fusion are presented in this paper. The design involves solving two important stages of group fusion, namely, similarity search and fusion (MAX rule), while addressing embarrassingly parallel and parallel reduction models. The sequential, optimized sequential and parallel OpenMP of group fusion were implemented and evaluated. The outcome of the analysis from these three different design approaches influenced the design of parallel CUDA version in order to optimize and achieve high computation intensity. The proposed parallel CUDA performed better than sequential and parallel OpenMP in terms of both execution time and speedup. The parallel CUDA was 5-10x faster than sequential and parallel OpenMP as both similarity search and fusion MAX stages had been CUDA-optimized.

  • In this paper, we present an approach to transmit data from the source to the destination through a minimal path (least-cost path) in a computer network of n nodes. The motivation behind our approach is to address the problem of finding a minimal path between the source and destination. From the work we have studied, we found that a Steiner tree with bounded Steiner vertices offers a good solution. A novel algorithm to construct a Steiner tree with vertices and bounded Steiner vertices is proposed in this paper. The algorithm finds a path from each source to each destination at a minimum cost and minimum number of Steiner vertices. We propose both the sequential and parallel versions. We also conducted a comparative study of sequential and parallel versions based on time complexity, which proved that parallel implementation is more efficient than sequential.

  • 본 논문에서는 신경회로망을 이용하여 아날로그 시 계열정보를 직접 처리할 수 있는 연상기억 시스템을 제안한다. 제안하는 시스템은 시 계열정보를 상기할 때 현재의 정보와의 일치 결과만으로 출력(상기결과)을 결정하는 것 외에 과거의 일치결과도 고려한 상태에서 출력을 결정하는 시스템이다. 시스템의 기본적인 능력을 조사하기 위하여 기억패턴을 주기계열로 그리고 하중은 전부 고정하는 조건으로 단순화하여 시뮬레이션을 행하여 오류정정 능력을 갖는 것을 확인하였다. 시간축 방향의 하중을 적절하게 설정하면 기억용량의 증대나 상기 오류의 저감 등의 효과가 기대된다.

  • 지난 몇 년간 스마트폰은 굉장히 빠른 속도로 발전하면서 생활 속에서 큰 비중을 차지하고 있다. 이러한 스마트폰에는 에너지 효율, 크기, 속도 면에서 모바일 기기에 적합한 Flash storage가 탑재되고 있다. 이 논문에서는 스마트폰에 탑재된 Flash storage를 기반으로 한 버퍼 교체 알고리즘들 가운데 Spatial Clock 알고리즘에 초점을 맞추고 있다. 그리고 이 알고리즘이 Video Streaming workload에서 성능 발휘를 하지 못한다는 점을 해결하기 위해 SWSC(Sequential Write Spatial Clock) 알고리즘을 제안하였다. 이 알고리즘은 dirty 페이지들이 연속적인 경우 sequential write를 수행한다. 따라서 write 수행시간을 줄일 수 있고 결과적으로 Video Streaming workload에서도 좋은 성능을 발휘할 수 있다.

  • 본 논문에서는 새로운 ASIC 구조로 최근에 관심을 모으고 있는 TLU형 FPGA를 위한 순차회로 기술 매핑에 관한 것이다. 본 고에서 제안하는 TLU형 FPGA를 위한 순차회로 기술 매핑방법은 먼저 6개 또는 7개의입력을가지는 조합 및 순차 노드에대해서 전처리 기를 사용하여 한 출력 CLB에매핑하고, 매핑안된나머지 중 순차회로합병 조건에 만족 하는 6개 혹은 7개 입력 변수를 갖는 노드부터 CLB에 매핑한다. 본 고에서 제안한 순차 회로 기술 매핑 방법이 간단하면서 만족스런 수행 시간과 결과를 얻었다. 여러개의 벤치마크 화로를 sis-pga(map_together 및 map_scparate)순차회로 합성 시스템과 비교 하였으며, 실험결과는 본 시스템이 sis-pga 보다 17% 이상 성능이 좋다는 결과를 보여 주고 있다.

  • In this paper, we propose a displacement measurement method based on deep learning using image data obtained from tensile tests of a material specimen. We focus on the fact that the sequential images during the tension are generated and the displacement of the specimen is represented in the image data. So, we designed sample generation model which makes sequential images of specimen. The behavior of generated images are similar to the real specimen images under tensile force. Using generated images, we trained and validated our model. In the deep neural network, sequential images are assigned to a multi-channel input to train the network. The multi-channel images are composed of sequential images obtained along the time domain. As a result, the neural network learns the temporal information as the images express the correlation with each other along the time domain. In order to verify the proposed method, we conducted experiments by comparing the deformation measuring performance of the neural network changing the displacement range of images.
