21세기 들어 디지털 카메라가 널리 보급되면서 사진을 이용하거나 사진을 위한 많은 연구들이 컴퓨터 그래픽스 커뮤니티에 소개되고 있다. 이러한 연구들은 계산 사진학이라고 불리고 있는데, 이 논문에서는 계산 사진학이 수 천년 사진학의 역사에서 어떤 흐름을 거쳐 발생했는지 설명한다. 또한 사진학의 역사를 패러다임의 전환으로 나누고, 계산 사진학이 어떠한 패러다임 전환기 결과물인지 설명한다. 이를 통해 계산 사진학의 향후 연구 방향을 제시하려 한다.

In this paper, we present few technical notes about the distance distribution paradigm for Mosaab-metric using 1, 2, and 3 grams feature extraction techniques to analyze composite data points in high dimensional feature spaces. This technical analysis will help the specialist in bioinformatics and biotechnology to deeply explore the biodiversity of influenza virus genome as a composite data point. Various technical examples are presented in this paper, in addition, the integrated statistical learning pipeline to process segmented genomes of influenza virus is illustrated as sequential-parallel computational pipeline.

Many computational models using computer program in agricultural engineering were proposed and introduced until now. These programs were developed based on procedure and structural program paradigm, so it's hard to reuse because programs become bigger and complex. In this study proposals a program paradigm that is easy to combine and reuse. Embedded engineering techniques are Java, JavaBean model, object-oriented programming.

With the emergence of a new paradigm called Open Science and Big Data, the need for data sharing and collaboration is also emerging in the computational science field. This paper, we analyzed data-driven research cases for computational science by field; material design, bioinformatics, high energy physics. We also studied the characteristics of the computational science data and the data management issues. To manage computational science data effectively it is required to have data quality management, increased data reliability, flexibility to support a variety of data types, and tools for analysis and linkage to the computing infrastructure. In addition, we analyzed trends of platform technology for efficient sharing and management of computational science data. The main contribution of this paper is to review the various computational science data repositories and related platform technologies to analyze the characteristics of computational science data and the problems of data management, and to present design considerations for building a future computational science data platform.

Japan Aerospace Exploration Agency has introduced a new terascale clusterd SMP system as a main compute engine of Numerical Simulator III for aerospace science and engineering research purposes. The system is using Fujitsu PRIMEPOWER HPC2500; it has computing capability of 9.3Tflop/s peak performance and 3.6TB of user memory, with about 1,800 scalar processors for computation. In this paper, we first present the performance evaluation results for aerospace CFD applications with hybrid programming paradigm used at JAXA. Next we propose a performance prediction formula for hybrid codes based on a simple extension of AMhhal's law, and discuss about the predicted and measured performances for some typical hybrid CFD codes.

The pre- and post-processor for finite element structural analysis considering the user-friendly device are developed by using GUI. These can be used on WINDOWS' environment which is realized the multi-tasking and the concurrency by object-oriented paradigm. They are designed to control integratedly the pre-processing, execution and the post-processing of the finite element structural analysis program on multiple windows. These object-oriented modeling approach can be used for complex integrated engineering systems.

창의적 사고와 융합이 중요시되는 4차 산업 혁명 시대를 성공적으로 맞이하기 위해 전 세계적으로 컴퓨팅 사고력(Computational Thinking: CT) 증진을 위한 코딩(coding) 교육이 대두되고 있다. 특히 MIT 미디어 연구소에서 개발한 스크래치(Scratch)를 활용한 코딩 교육은 기존의 전통적인 교육패러다임을 벗어나서, 학습자들이 능동적이고 협력적 활동에 참여하는 구성주의 교수법을 강조하고 있다. 하지만 이러한 교육 패러다임 변화에 대한 인식이 부족하기 때문에 실제 학교나 사교육 현장에서는 코딩 교육이라는 명목하에 프로그래밍 언어에 관련된 테크닉이 주로 강조 되는 경향이 있다. 이에 본 연구는 구성주의적 교수-학습에 입각한 CT 평가 도구를 개발하고 실행하는 것에 초점을 두었다. 그리고 CT 자기 평가 도구의 교육적 가치를 연구하기 위해 '컴퓨팅 사고력을 활용한 문제해결'이라는 과목을 수강한 초등예비교사들이 CT 역량 평가 루브릭을 활용한 결과를 분석하였다. 본 연구의 결과를 통해 협력이 강조되는 구성주의 교수법을 반영한 CT 자기 평가를 디자인하고 실현하는 과정을 매개로 하여, 초등예비교사들이 문제해결 과정을 체험하고 CT역량을 증진시키는 것을 확인 할 수 있었다. 본 연구의 결과를 통해 도출된 CT 교육 및 평가에 대한 개선점을 제언하였다.

Nowadays personal users create a variety of multi-media contents and share them with others through various devices over the Internet since the concept of user created content (UCC) has been widely accepted as a new paradigm in today's multi-media market, which has broken the boundary of contents providers and consumers. This paradigm shift has also introduced a new business model that makes it possible for them to create their own multi-media contents for commercial purpose. This paper proposes a tangible virtual studio using augmented reality to author multi-media contents easily and intuitively for personal broadcasting and personal content generation. It provides a set of tangible interfaces and devices such as visual markers, cameras, movable and rotatable arms carrying cameras, and miniaturized set. They can offer an easy-to-use interface in an immersive environment and an easy switching mechanism between tangible environment and virtual environment. This paper also discusses how to remove inconsistency between real objects and virtual objects during the AR-enabled visualization with a context-adaptable tracking method. The context-adaptable tracking method not only adjusts the locations of invisible markers by interpolating the locations of existing reference markers, but also removes a jumping effect of movable virtual objects when their references are changed from one marker to another.

In this paper, we focus on a novel Internet architecture, based on the urbanization of virtual machines. In this approach, virtual networks are built linking specific virtual elements (router, switch, firewall, box, access point, etc.). A virtual network represents a network with an independent protocol stack that shares resources from the underlying network infrastructure. Virtualization divides a real computational environment into virtual computational environments that are isolated from each other, and interact with the upper computational layer, as would be expected from a real, non-virtualized environment. Metamorphic networks enhance several concepts related to future networks, and mainly the urbanization of virtual machines. We present this new paradigm, and the methodology, based on the worldwide metamorphic network platform "M-Net". The metamorphic approach could solve many complex problems, especially related to Cloud computing services.
