SURF is a compliance engine, checking document content against detail in an established agreement. It provides a single vehicle for handling documentary trade settlement, regardless of the risk profile and financing requirements of the parties involved. That is, SURF, a Value Added Service connected to the Core Messaging Platform, is a documentary trade settlement service. It offers users of the system automated document compliance checking and a tool to manage the workflow in connection with documentary trade settlement. The Service supports varying degrees of risk transfer between buyer, sellers and banks and supports transactions from open account to more complex Letters of Credit.

최근의 비즈니스 환경은 조직 내의 업무 프로세스 자동화뿐만 아니라, 조직간의 상호 운용을 통한 복잡하고 거대한 서비스들의 처리를 요구하고 있다. 업무 처리 복잡도와 요청 밀집도가 높은 워크플로우 서비스를 처리하기 위한 시스템이 e-chautuauqua 워크플로우 엔진이다. e-chautuaqua 워크플로우 엔진은 대량의 워크플로우 인스턴스 처리에 목적을 둔 초대형 워크플로우 기반의 엔진이기 때문에, 워크플로우 프로세스에 대한 예외 발생을 최소화하는데 목적을 둔 트랜잭션 워크플로우 기반의 엔진에 비해서 신뢰성 보장이 미흡하다는 문제점을 가진다. 따라서, 본 논문에서는 신뢰성 강화와 비즈니스 트랜잭션의 안정적인 처리를 위한 e-chautauqua 워크플로우 엔진의 예외 처리 메커니즘에 대해 기술하고자 한다.

워크플로우의 응용 분야 중에서 전자상거래의 B2B 나 B2C 에 적용하는 사례가 빈번히 발생하는 추세이다. 이에 따라 워크플로우 관리 시스템의 엔진의 구조 역시 변화가 이뤄져야 한다. 다수의 전자 상거래를 처리하기 위해서 시스템의 구성을 실행 객체가 아닌 데이터화를 시켰다. 이는 기존의 표준에서 제안된 구조와 다른 구조이다. 이를 통해 시스템의 부하와 비용을 줄이는 방법을 제시하고, 본 논문에서 제시한 엔진을 바탕으로 하는 워크플로우 관리 시스템을 소개한다.

워크플로우 시스템은 비즈니스 환경에서 프로세스의 자동화 수행을 통해 업무 처리의 효율성 및 성능을 극대화시켜주는 미들웨어 시스템이며 워크플로우 엔진은 이러한 비즈니스 서비스의 실질적인 수행을 컨트롤 및 관리해주는 역할을 한다. 워크플로우 클라이언트로부터의 서비스 요청에 대한 처리를 위해 워크플로우 엔진은 엔진 내부의 핵심 컴포넌트들의 연동에 의해 생성되는 서비스 인스턴스들의 처리 행위를 통해 서비스를 수행하며, 서비스 처리를 하면서 발생되는 이벤트들에 대해서 로그를 기록한다. 이러한 로그 데이터들은 워크플로우 모니터링 분석에 중요한 근거 자료로서 사용되며, 워크플로우 웨어하우징 및 마이닝등의 분야에서 주요 근간 데이터로서 사용될 수 있다. 본 논문에서는 자체 제작된 e-chautauqua 초대형 워크플로우 시스템을 배경으로 초대형 워크플로우 라는 환경에서 대용량의 로그를 어떻게 구성하는지에 대해서도 살펴볼 것이며, 워크플로우 엔진을 구성하는 핵심 컴포넌트들의 연동에 의해 수행되는 서비스 인스턴스들의 이벤트들이 어떠한 모습으로 로그 메시지를 구성하게 되는지에 대한 로그 메시지 포맷에 대한 전반적인 워크플로우 로깅 메커니즘에 대해 기술하고자 한다.

현재의 급변하고 있는 비즈니스 환경은 기업 내부의 인트라적인 업무 처리 뿐만 아니라, 기업과 기업간의 상호교환을 통한 업무 수행을 요구하고 있으며, 이러한 요구 사항에 적절하게 대응할 수 있는 전략 개념이 프로세스 상호운용성이다. 본 논문에서는 현재의 비즈니스 시장에서 이슈화되고 있는 프로세스 상호운용성을 실제적으로 구현하고자 하는 과정의 일환으로 워크플로우 표준 단체인 WfMC(Workflow Management Coalition)에서 제안하는 상호운용성 표준 메시지 프로토콜인 Wf-XML 2.0을 지원하는 프로세스 엔진의 시스템 아키텍쳐를 구성하고자 하며, 기반이 되는 프로세스 엔진은 자체 연구 제작된 e-chautauqua라는 워크플로우 시스템을 이용하여 프로세스 상호운용성이 가능할 수 있도록 확장 설계하고자 한다.

Common Criteria(CC) was announced in June, 1999 in order to solve a problem which be happened by applying a different evaluation criteria among nations. Currently, a official version is v2.2 and v3.0 is a draft version. Because an evaluation demand is increased in the inside and outside of the country, an evaluation market growth is expected. Also, It needs methodology and work automation and project management for evaluation. In this paper, we propose A CC based Security Evaluation Management System(CC-SEMS) that is managing evaluation resources(deliverables , evaluation criteria, evaluators) and is useful in evaluation environment efficiently. CC-SEMS is to have integrated project management, workflow management, process management and is composed of deliverables, Evaluation Activity Program(EAP), Management Object(MO), Evaluation Database(EDB), Evaluation Workflow Engine(EWE).

BPEL is used in various domains since it can describe the flow of works according to conditions and rules, and it can call web services in service-oriented computing environments. However, new functions that are not provided by BPEL grammar are required in specific domains. Generally, when new functions are required, the domain-specific language should be newly defined and developed, which requires high development cost. In this regard, a new function needs to be defined and added instead of developing domain-specific language with the new functions added. However, such methods only allow an addition of a single function, and it is difficult to design and add new functions according to the needs. This paper defines XAS4B document, which extends the BPEL grammar function through XML schema in order to add new functions, and proposes BPEL engine generator that generates BPEL engine with the new functions added by processing the document. The XAS4B document enables the creation of a new grammar added to BPEL using XML schema. It also shows the process of adding new functions to BPEL engine using AspectJ, JAVA implementation of aspect-oriented programming. The proposed system can add new functions using AspectJ without modifying BPEL engine. This allows the provision of new functions at low cost in various domains.

These days, VR contents are created in three ways: CG based method, game engine based method, and live action shooting method. The most universal method is live action shooting. So far, most live actions are shot with action cams. Therefore, this method is different from professional image production method for movies and TV dramas. This study tries to point out the difference between professional image production method and action cam based shooting method, and proposes an alternative. The proposed method is log shooting based HDR filming and editing. As the result of test shooting and editing, the proposed method was able to obtain more color information than conventional action cam based shooting method and thereby to implement high-definition images which are hard in an action cam.

Effective monitoring and testing during each step are essential for document verification in research and development (R&D) projects. In software development, proper testing is required to verify it carefully and constantly because of the invisibility features of software. However, not enough studies on test processes for R&D projects have been done. Thus, in this paper, we introduce a Test Maturity Model integration (TMMi)-based software field R&D test process that offers five integrity levels and makes the process compatible for different types of projects. The Software & Systems Process Engineering Metamodel (SPEM) is used widely in the software process-modeling context, but it lacks built-in enactment capabilities, so there is no tool or process engine that enables one to execute the process models described in SPEM. Business Process Model and Notation (BPMN)-based workflow engines can be a solution for process execution, but process models described in SPEM need to be converted to BPMN models. Thus, we propose an approach to support enactment of SPEM-based process models by converting them into business processes. We show the effectiveness of our approach through converting software R&D test processes specified in SPEM in a case study.

Achieving realistic visual quality while maintaining optimal real-time rendering performance is a major challenge in evolving computer graphics and interactive 3D applications. Normal mapping, as a core technology in 3D, has matured through continuous optimization and iteration. Hybrid normal mapping as a new mapping model has also made significant progress and has been applied in the 3D asset production pipeline. This study comprehensively explores the hybrid normal techniques, analyzing Linear Blending, Overlay Blending, Whiteout Blending, UDN Blending, and Reoriented Normal Mapping, and focuses on how the various hybrid normal techniques can be used to achieve rendering performance and visual fidelity. performance and visual fidelity. Under the consideration of computational efficiency, visual coherence, and adaptability in different 3D production scenes, we design comparative experiments to explore the optimal solutions of the hybrid normal techniques by analyzing and researching the code, the performance of different hybrid normal mapping in the engine, and analyzing and comparing the data. The purpose of the research and summary of the hybrid normal technology is to find out the most suitable choice for the mainstream workflow based on the objective reality. Provide an understanding of the hybrid normal mapping technique, so that practitioners can choose how to apply different hybrid normal techniques to the corresponding projects. The purpose of our research and summary of mixed normal technology is to find the most suitable choice for mainstream workflows based on objective reality. We summarized the hybrid normal mapping technology and experimentally obtained the advantages and disadvantages of different technologies, so that practitioners can choose to apply different hybrid normal mapping technologies to corresponding projects in a reasonable manner.
