This paper formally defines a role-driven security and access control model of a business process in order eventually to provide a theoretical basis for realizing the secured business process management systems. That is, we propose a graphical representation and formal description of the mechanism that generates a set of role-driven security and access control models from a business process modeled by the information control net(ICN) modeling methodology that is a typical business process modeling approach for defining and specifying business processes. Based upon the mechanism, we are able to design and accomplish a secured business process management system that provides an unified resource access control mechanism of the business process management engine domain's and the application domain's. Finally, we strongly believe that the secured access control policies from the role-driven security and access control model can be easily transformed into the RBAC(Role-based Access Control) model that is a standardized security technology for computer and communications systems of commercial and civilian government organizations.

In this paper deals with the problem of modeling customs information and the criterion for controlling its reliability in the process of managing customs clearance of goods is considered. As the main object of the study, the information of the cargo customs declaration, which is submitted to the customs authorities in electronic form for customs clearance of goods, is considered. The main criteria for determining the reliability of customs information, based on the classical methods used by other fields of science, are given.

Knowledge management is an essential part for gaining competitive advantage. The knowledge management system deals with information gathering, process, and implementation for the organizational performance advantage. The study integrates knowledge management in view of an internal organizational information processing structure and external strategic issue management system. This means that the coordination between internal systematic process and external scanning mechanism is essential for organizational success.

Design of manufacturing process, in general, facilitates the creation of new process that may potentially harm the workers. Design of safety-guaranteed manufacturing process is, therefore, very important since it determines the ultimate outcomes of manufacturing activities involving safety of workers. This study discusses application of information-theoretic measure (entropy) to safety assessment of manufacturing processes. The idea is based on the general principles of design and their applications. Some examples are given.

Over the past decade, changes in product development processes and increased consumer demands have dramatically influenced engineering working practices and targets. The information technology revolution has made its appearance concurrent to this relentless escalation in product engineering requirement. It has offered hopes for improved productivity despite these increasing demands. The wide availability of personal computing power, virtually inexhaustible sources of information and an abundance of computerized engineering tools have created great expectations. Knowledge information modeling system and database were developed using ASP and Microsoft SQL 2000 Server to share the DB that can be utilized to process on the web.

이 연구는 Sentaurus Process를 이용하여 실리콘(Si) 웨이퍼에 각각의 불순물들의 도핑 농도를 모의실험 하여 공정 방법과 순서, 온도, 깊이에 따른 도핑 농도의 변화를 나타내었다. 입력한 값에 대한 수치를 한눈에 알아 볼 수 있으며 공정이나 깊이, 도핑 농도에 따라 불순물의 집중도와 공정 방법에 따른 소자 특성의 변화를 한눈에 알아 볼 수 있어서 Sentaurus Process를 이용한 연구를 통해 우수한 소자를 개발하는데 도움이 되리라 본다. 이 연구에서는 공정 파라미터 값의 변화에 따른 도핑 분포를 Sentaurus Process 시뮬레이션을 통하여 관찰할 것이다.

The demands for continuous process optimization require a radical rethinking of how information systems are designed and constructed. Information systems must be capable of sustained, graceful change in response to evolving business requirements. This proposition is supported by the fact that information systems have helped increase productivity only when they were built to support new and better ways of conducting the business. In such context, business process engineering (BPF) is recognized the first but most critical stage in developing information systems as well as in launching business improvement and innovation projects. However, more often, there exist great gaps and inconsistencies between the results of BPE and the business itself, which turn into huge maintenance overhead during an information system lifecycle. In order to solve such an ever lasting problem, this paper orthogonal models, procedure, guide, and work flow are constructed in our engineering discussions focus on decentralized organizations, the method is general enough to be applied easily to other types of organizations without difficulties.

While considerable research suggests that users' uncertainty gradually decreases, as they proceed through the information seeking process, others argue that it can arise at any stage of their information seeking process. Reflecting the latter view, this study examined user perceptions of uncertainty in the final stage of users' information seeking process, the stage of search results evaluation. Considering the significance of Web search engines for academic study, this study investigated the relevance decision stage of scholarly researchers in the field of science, who use Web search engines for their academic study. Based on the analysis of the users' uncertainty, this study provided implications to improve information systems and Web contents design.

The Internet has made a huge impact on the way we, as humans, communicate. During the last decade a series of new communication mediums have emerged and communication protocols have come and gone. This puts new requirements on the development process and architecture of the communication platforms, operated by communities, in order to proactively ensure support for future communication protocols. Even further, additional requirements are added when the software itself will be maintained by a community. In this paper we explore the world of Open Source Software. We present our suggestions of usable design-principles and our process in developing a sustainable information system.

Effective information "query and retrieval" process is one of the fundamental problems in the field communication and information science and has become especially important due to dramatic increase in magnitude of information to be processed in modern era. Of particular importance at information exchange process, our study focuses on compositions of proper queries and retrieval of rural amenity resources. This particular task has been difficult because the rural amenity resources does not necessarily carry measurable traits and also contains huge amount of data. In this Letter, we propose an alternative approach to the architecture of the resource information system by use of a noble retrieval algorithm based on ontology. Test of efficiency and applicability of this new scheme was conducted, and it showed that this has possibility to be effective information retrieval process of rural amenity resources.
