Nowadays most vehicles are equipped with a variety of electronic devices to improve user convenience as well as its performance itself. In order to efficiently interconnect these devices with each other, Controller Area Network (CAN) is commonly used. However, the CAN requires reconfiguration of the entire network when a new device, which is capable of supporting both of transmission and reception of data, is added to the existing network. In addition, since CAN is based on the collision avoidance using address priority, it is difficult that a new node is assigned high priority and eventually it results in transmission delay of the entire network. Therefore, in this paper we propose a new system component, called CAN coordinator, and design a new CAN framework capable of supporting plug and play functionality. Through experiments, we also prove that the proposed framework can improve real-time ability based on plug and play functionality.

This study aims at what is required knowledge and ability to pre-service math teachers in teacher certificate examination. First, the items are analyzed and among questions of discipline of mathematics education in the last five years are analyzed and classified. Second, an analytical framework suitable for item analysis is examined and the items are analysed by the analytical framework. Finally, helpful implications for discipline of mathematics education assessment can be drawn from this study. It is found that the discipline of mathematics education assessment has the following characteristics: 1) It assesses specific content of the assessment component; 2) It assesses a teacher's theoretical knowledge, practical knowledge and creative knowledge in terms of teaching ability; 3) There are six cognitive assessments; 4) There is an item for difficulty adjustment.

Fiber reinforced materials have favorable mechanical properties. Moreover, the strength to weight ratios of this material is superior to those of most alloys. Comparing to the metals, it showed many other advantages as well, including non-corrosiveness, translucency and easy repair characteristic. Since, it has the potential for the chair-side and laboratory fabrication, it is not surprising that fiber reinforced composites offer the potential for use in various applications in dentistry. To make the well-fitted restorations, Fiber reinforced composite (FRC) has been suggested as an alternative framework material for the implant supported fixed prosthesis. Two fixed partial denture fabrication procedures were tried. Vectris fiber was pressed to the EsthetiCone gold cylinder on the implant positioned cast. And then, Targis were added on it. In the other method, we used the customized component using UCLA abutment. The beads for retaining the Vectris fiber were added on the abutment. If careful laboratory and clinical techniques were done, these two techniques would fulfill the demands of the esthetics and strength.

As the applications and services based on the augmented reality are widely spread in various industry and public domain information dissemination areas, it is naturally necessary to provide the common information framework which can describe required detailed information for services. JPSearch which is released for unified access to image repositories can be utilized in this kind of infrastructure due to that the framework for augmented reality needs a constituent component which supports image repositories. In this paper, we propose a metadata schema which is designed for information architectural framework in the environment of augmented reality based on workflow. The proposed information schema can support the workflow of augmented reality related production system and service implementation.

Due to recent growing interest in autonomous software agents and their potential application in areas such as electronic commerce, the autonomous negotiation become more important. Evidence from both theoretical analysis and observations of human interactions suggests that if decision makers have prior information on opponents and furthermore learn the behaviors of other agents from interaction, the overall payoff would increase. We propose a new methodology for a strategy finding process using data mining in autonomous negotiation system; ANSIA(Autonomous Negotiation System using Intelligent Agent). ANSIA is a strategy based negotiation system. The framework of ANSIA consists of three component layers; 1) search agent layer, 2) data mining agent layer and 3) negotiation agent layer. ANSIA is motivated by providing a computational framework for negotiation and by defining a strategy finding model with an autonomous negotiation process.

The rapid growth of communication and globalization has changed the software engineering process. Security has become a crucial component of any software system. However, software developers often lack the knowledge and skills needed to develop secure software. Clearly, the creation of secure software requires more than simply mandating the use of a secure software development lifecycle; the components produced by each stage of the lifecycle must be correctly implemented for the resulting system to achieve its intended goals. This study demonstrates that a more effective approach to the development of secure software can result from the integration of carefully selected security patterns into appropriate stages of the software development lifecycle to ensure that security designs are correctly implemented. The goal of this study is to provide developers with an Integrated Security Development Framework (ISDF) that can assist them in building more secure software.

로봇은 다양한 기능을 하는 기기들이 유기적으로 결합하여 동작한다. OPRoS (Open Platform for Robotic Services) 프레임웍은 여러 기관 및 개발자가 로봇에 탑재되는 부품을 컴포넌트 형태로 개발하여 자유롭게 결합시킬 수 있는 통합 개발 환경을 제공한다. 로봇의 신뢰성 있는 동작을 확보하기 위해 개발자는 또 다른 개발자가 만든 컴포넌트들과 상호 운용을 시험해야 한다. 이를 위해 가장 먼저, 개발된 컴포넌트와 의미 있는 결합을 할 수 있는 타 컴포넌트를 검색할 수 있어야 한다. 본 연구는 OPRoS 프레임웍이 제공하는 인터페이스에 의미를 부여하고 모델화 하여 의미 모델간의 매핑 기법으로 연계 가능한 타 컴포넌트를 검색할 수 있는 로봇 상호 운용성 평가 시스템을 제시한다.

Semantic clustering is important to various fields in the modem information society. In this work we applied the Independent Component Analysis method to the extraction of the features of latent concepts. We used verb and object noun information and formulated a concept as a linear combination of verbs. The proposed method is shown to be suitable for our framework and it performs better than a hierarchical clustering in latent semantic space for finding out invisible information from the data.

The objective of the paper is to clarify a methodology based on the use of the existing component mode synthesis methods for the case of two damped substructures which are coupled through a linking viscoelastic flexible substructure and for which the structural modes with free geometrical interface are used for each main substructure. The proposed methodology corresponds to a convenient alternative to the direct use either of the Craig-Bampton method applied to the three substructures (using the fixed geometric interface modes) or of the flexibility residual approaches initiated by MacNeal (using the free geometric interface modes). In opposite to a geometrical interface which is a topological interface on which there is a direct linkage between the degrees of freedom of substructures, we consider a physical flexible interface which exists in certain present technologies and for which the general framework linear viscoelasticity is used and yields a frequency-dependent damping and stiffness matrices of the physical flexible interface.
