분산 시스템 환경에서 여러 시스템에 정보를 전송하기 위한 방법으로 최근 EAI 의 DB Trigger 및 Redo Log 등을 이용한 실시간 데이터 통합 방식을 적용해 왔다. 그러나 기업에서 순차적인 배치 프로세스들을 통해 처리하는 대량의 데이터에 대해 기존의 EAI 의 데이터 통합 방식을 사용할 경우 모든 변경 건수에 대해 이벤트가 발생하여 Source 시스템의 부하 및 통합 성능상의 문제점이 있다. 본 논문에서는 순차적인 배치 프로세스들을 EAI 의 프로세스 레벨 통합을 적용하여 최종 변경된 데이터에 대해서만 통합하도록 하여 통합 처리 시간을 단축할 수 있는 방법을 제시하고자 한다.

Edge detection is one of issues with essential importance in the area of image process. An edge in image is a boundary or contour which a significant change occurs in image intensity. In the paper, we process edge detection algorithms which are based on Potts automata. The dynamical behavior of these automata is completely determined by Lyapunov operators for sequential and parallel update. If Potts Automata convergence to fixed points, then it can be used to image processing. From the generalized Potts automata point of view, we propose a Potts Automata technique for detecting edge. Based on the experimental results we discuss the advantage and efficiency.

Current rendering processors are organized mainly to process a triangle as fast as possible and recently parallel 3D rendering processors, which can process multiple triangles in parallel with multiple rasterizers, begin to appear. For high performance in processing triangles, it is desirable for each rasterizer have its own local pixel cache. However, the consistency problem may occur in accessing the data at the same address simultaneously by more than one rasterizer. In this paper, we propose a parallel rendering processor architecture, called DAVID II, resolving such consistency problem effectively. Moreover, the proposed architecture reduces the latency due to a pixel cache miss significantly. The experimental results show that DAVID II achieves almost linear speedup at best case even in sixteen rasterizers.

Recently, most network communication chips are powered; which causes power consumption a heavily constraint. Since, there are a lot of expectations on TPM to have a high performance in terms of authentication of its device. During the design process there is a need to estimate the security of the design but it always when the chip has already been manufactured. This paper designed a power consumption control monitor in TPM device which evaluate the voltage drop during processing of use. Therefore we will analyze the power consumption profile. The result shows that the voltage drop leads to vulnerability of the system to attackers during communication process.

Personal Software Process (PSP)에서 개인 개발자들이 수행해야 되는 측정 및 분석 활동이 제시된다. 측정 및 분석 활동의 일관되고 지속적인 수행으로 개발자들은 소프트웨어 품질 향상, 보다 정확한 예측, 개인 역량의 객관적인 평가, 개인 프로세스의 정량적 관리 등의 이득을 얻을 수 있다. 측정 및 분석 활동에서 신뢰성 있는 데이터의 수집이 무엇보다 중요하다. 하지만, 데이터 수집의 높은 오버헤드(overhead)와 컨텍스트 스위칭(context switching)의 문제로 인하여 신뢰성 있는 데이터의 수집에 많은 어려움이 존재한다. 이러한 어려움을 감소시키기 위해 자동 데이터 수집 및 분석 기법이 연구되어 왔다. 본 논문에서는 기존의 자동 데이터 수집 및 분석 기법을 확장하여 웹 애플리케이션 개발에서의 개인 프로세스 데이터를 자동 수집 및 분석 하는 도구를 설명한다.

On account of the text based mail system has it's limit to support multimedia applications, GUI based mail system platform was developed to control document flow and automatize information process. The existing mail systems's to transmit data must need additional functions to automate document flow control. The platform of document flow control is deeply related to EDMAS(Electronic document Management System), workflow, Electronic Banking, DMS(Document Management System) automation, so it needs an ability to control proper data and document correctly. To resolve this problems, we are need of browser and engine to design work flow and to control documents flow. In this paper, we develope a mail browser to design document flow by follow user's requirements. This system can generate executive script code for document flow, and we add the function of workflow and process management to automatize the document flow in this system, and then we implement this Data flow engine.

Industrialization and modernization of the beginning of the IT industry is growing very fast. Since telecommunications industry was developed rapidly, technologies about miniaturization and high-precision of parts have been actively developed to lead information revolution. generally, the entire shear surface of the product applying fine blanking technology must be very precise. Fine blanking is used to save cost by avoiding post-processing of the product. When using press blanking, it spends a lot of money on the production by using many post-processing. Fine blanking typically used in 0.5~18 mm thick steel plate. Because a lot of post-processing cost can be used to process, except for fine blanking. In order to develop components "CHANCE CONTENTS" in the fine blanking process, the purpose of this study is to minimize the edge of the bridge, secured 95% of the material thickness of the shear surface using the 1.6 mm thickness of the material SPCC. Blanking process by introducing after changing thickness through forging process, due to change in vee-rring force and counter force, the experimental amount of depressions and flatness and the shear surface were analyzed.

Real life has been actively utilizing storage from anywhere automobiles and Aviation field etc to the development of storage. Recent Big Data is stored as a number of data storage and data distribution processing emerged in research has been actively conducted to process the data. But many bottlenecks or processing speed slows down when you request the data at the same time a problem arises. In this paper consider should be used in the field of big data storing and processing large amounts of data, the process data more efficiently when the number of data request and data suggest that the weight-effective, manageable data processing system algorithm.

Organizations are attempting a digital transformation that converts physical business processing into virtual business processing. Through this digital transformation, organizations are overcoming time and space constraints and creating competitiveness. The digital transformation of this work environment has been accelerated as many organizations have implemented remote work due to the recent COVID-19 pandemic. This study focused on business process virtualizability, which is the result of the rapid digital transformation of the work environment. Business process virtualizability is the resulting quality, such as the suitability or excellence of business processing in a virtual environment. This research model is the effect of process, IT and organizational characteristics on business process virtualizability. As a result of the verification of people who have experienced remote work in a virtual environment, first, it was confirmed that, in terms of process characteristics, sensory requirements affect business process virtualizability, but relationship requirements, synchronism requirements, and identification and control requirements do not. Second, in terms of IT characteristics, it was confirmed that representation and reach affect business process virtualizability. Third, it was confirmed that, in terms of organizational characteristics, job autonomy affects business process virtualizability, but evaluation unfairness does not. This study found that representation and reach of IT had the most significant influence on business process virtualizability, job autonomy was next, and sensory requirements had the lowest influence. This presents practical implications for organizations to increase the success potential of business process virtualizability.
