In this letter, we analyze the problems with the existing telematics service systems that have been dependently developed and provided on a specific mobile network infrastructure. Then, we suggest methods to solve the problems and propose an architecture of the gateway and framework to implement our methods. We also verify the effectiveness of the suggested architecture through a comparison with an existing telematics system. With this architecture, it is possible to develop service applications without knowledge of the underlying mobile network technology and the system integration methods.

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.

In the recent business environment, risks related to product safety problems are increasing. These are arising from various factors such as increasing product and production complexity, supply chain diversification, enhanced PL (product liability) law and strengthening regulations of the government. Accordingly, ISO (international organization for standardization) published standards of PSMS (product safety management system) for suppliers such as ISO 10377 and ISO 10393. Meanwhile, the ISO 9001 QMS (quality management system) was revised in 2015, and it has established itself as an effective tool that can consistently meet the various requirements of stakeholders and promote customer satisfaction. This study aims to suggest an integration framework of QMS and PSMS based on the recent ISO international standards. To this end, firstly, the relationship between QMS and PSMS is studied based on the quality and product safety definitions, PDCA (plan-do-check-act) cycle and risk-based thinking. Secondly, the requirements of ISO 10377 and ISO 9001 are compared and classified as the common and ISO 10377 specific requirements. Finally, integration steps of two systems are suggested and guidelines that can systemize the integrated requirements are presented in the aspect of processes and documentation. This study is expected to be used as a guideline that helps companies those have already acquired QMS certification to build an international-level product safety management system early.

Typical multi-tier client/server architecture includes various and complex objects scattered around the network. Those objects must be clearly identified and designed. Then, their interface must be well-defined so that the integration can be done without major difficulties. This paper presents an application framework to increase reuse and to accomplish architectural simplicity in information systems development. Each component of the architecture is identified and designed. The proposed architecture of the application framework provides the fundamental structure for developing individual functions of an information system. Resulting architectural simplicity achieves effective and efficient maintenance throughout the lifecycle of the information systems. Although the framework aims at the reuse within a project, the productivity of information systems development across projects will be greatly improved eventually. Cases are discussed to evaluate the practicality of the architecture presented.

This paper tries to extend the conventional conceptual framework of the Internet of Things (IoT) so as to reify an advanced pervasive IoT-community collaboration concept, which is called the process-aware Internet of Things. The extended conceptual framework is embodied as a referential architecture that can be a standardized reference model supporting the conceptual integration of the Internet of Things and the process awareness. The extended referential architecture covers the full range of the architectural details from abstracting the process-aware behavioral semantics to reifying the IoT-process enactments. These extended framework and architecture ought to be the theoretical basis for implementing a process-aware IoT-community computing system supporting process-aware collaborations of Things in pervasive computing environments. In particular, we do point up that the proposed framework of the process-aware Internet of Things is revised from the Internet of Things framework announced in ITU-T SG13³ Y.2060 [26] by integrating the novel concept of process awareness. We strongly believe that the extended conceptual framework and its referential architecture are able to deliver the novel and meaningful insight as a standardized platform for describing and achieving the goals of IoT-communities and societies.

미래의 해양 전장 환경에 대비하고 다양한 요구사항을 만족하기 위해 함정을 구성하는 여러 체계의 기능이 고도화되고 다양화되고 있다. 함정의 승조원 수는 제한되어 있어 결국 한명의 승조원이 담당하는 임무와 운용 화면의 수는 늘어나고 있다. 본 논문에서는 REST 아키텍처를 이용하여 함정 내 각 체계와의 연동을 통해 체계의 정보와 서비스를 자함 객체로 통합하고 HTTP와 JSON 기반의 API 형태로 제공하는 함정 통합 서비스 프레임워크를 제안한다. 그리고 이를 전투체계 테스트베드에서 구현하고 성능을 측정하여 해군함정에 적용 가능함을 입증하였다. 본 논문에서 제시된 프레임워크를 실제 함정에 도입한다면, 체계 간의 기능이 통합된 화면의 설계가 가능하게 되어 승조원이 효율적으로 함정을 운용할 수 있을 것이다.

This paper introduces an adaptive and integrated utterance verification (UV) framework using minimum verification error (MVE) training as a new set of solutions suitable for real applications. UV is traditionally considered an add-on procedure to automatic speech recognition (ASR) and thus treated separately from the ASR system model design. This traditional two-stage approach often fails to cope with a wide range of variations, such as a new speaker or a new environment which is not matched with the original speaker population or the original acoustic environment that the ASR system is trained on. In this paper, we propose an integrated solution to enhance the overall UV system performance in such real applications. The integration is accomplished by adapting and merging the target model for UV with the acoustic model for ASR based on the common MVE principle at each iteration in the recognition stage. The proposed iterative procedure for UV model adaptation also involves revision of the data segmentation and the decoded hypotheses. Under this new framework, remarkable enhancement in not only recognition performance, but also verification performance has been obtained.
