  • This paper presents a novel method to design and implement mobile u-health system by defining the essential elements of mobile healthcare services. We choose common service elements for the proposed u-healthcare scheme and design the service platform. Especially we focus on automatic feces or urine sensing u-care scheme to prove the effectiveness of our platform. We construct the system with sensing part with a manikin and a diaper wireless communication part with feces or urine sensing data, and coordinator system based on the u-health platform defined in this paper. Experimental results show that our scheme is useful in the area of u-care service for the handicapped, the elderly, and patients who can hardly move by themselves. In addition the designed scheme offers a realized u-care scheme with the purpose of advanced developing tools for application or service developers.

  • Our platform introduced in this paper is based on DAVIC specifications which define high quality multimedia services with some extensions to provide user friendly and uniform interface to its users. We designed and implemented an integrated service platform for high quality interactive multimedia services, swithed digital broadcasting, and Internet services. The integration in terms of a service provider system, a delivery system, and a service user system is taken into account. Our research results in the development of integrated high quality interactive and digital broadcasting multimedia services with web-based common user interface and its experience will be feedback to the field trial service which will be launched from next year.

  • In this paper, we propose the design of railway safety common data model to provide common transformation method for collecting data from railway facility fields to Real-time railway safety monitoring and control system. This common data model is divided into five abstract sub-models according to the characteristics of data such as 'StateInfoMessage', 'ControlMessage', 'RequestMessage', 'ResponseMessage' and 'ExtendedXXXMessage'. This kind of model structure allows diverse heterogeneous data acquisitions and its common conversion method to DDS (Data Distribution Service) format to share data to the sub-systems of Real-time railway safety monitoring and control system. This paper contains the design of common data model and its DDS Topic expression for DDS communication, and presents two kinds of data transformation case studied for verification of the model design.

  • In this review, several new technologies considered when providing an open service environment in a mobile communication network are described. Recently, 3GPP developed some standards related to IoT services for opening a service platform in an SCS environment based on the OSA concept in a 3GPP LTE system. Similarly, the development of a new framework is underway to allow a plurality of services to commonly use an API environment in which a service provider or client accesses a 5G mobile communication system. Extending the existing LTE SCEF concept, the standardization of the northbound API is applied in the 5G CAPIF environment. Therefore, it is possible to construct a framework that facilitates access from outside, and takes advantage of the common management of various open service environments. An open service platform environment is expected to play an important role in transforming a network with simple connectivity services into a variety of new service markets, or into a service environment that can create added value.

  • 모바일 융합 서비스를 개발하기 위해 단순 컴포넌트의 조립(integration)이나 합병(merge)과 융합 서비스를 식별하는 기존의 개념만으로 부족하다. 비즈니스 서비스 모델에 적합한 비즈니스 기능을 가진 융합 서비스를 지원하는 응용 시스템 개발을 위해 비즈니스 서비스 모델에서부터 서비스 모델로의 매핑과 다양한 자산(assets)정보가 필요하며 이들을 설계 단계에서 구현 단계를 지원하는 적절한 프레임 워크가 절대적으로 필요하다. 따라서 본 논문에서는 소프트웨어 집약적인 신기술을 도입하여 시장 전략과 융합 모바일 도메인에 적합한 소프트웨어 개발 도구 및 환경 지원을 위한 모바일 융합 서비스 기반 공통 프레임워크(SOCF:Service Oriented Common Frameworks)를 연구하며 실생활의 모바일 서비스가 제공자와 고객 간에 재사용 단위의 추상화 수준을 단순 컴포넌트를 넘어 서비스 제공과 사용사이(provide/consume)의 서비스 수준까지 확대하여 다양한 서비스 자원들을 통합하고 재사용하여 서비스 융합 시스템 개발을 지원하는 프레임워크 설계 및 구현에 관한 내용을 서술한다.

  • This study aimed to evaluate how universal design principles are embodied in the Public Service Center. It will be used for planning the basic materials of the interior environmental design for Public Service Center facilities and for developing ways to improve interior environments in order for them to be conveniently used. In studying a method, we conducted an Universal Design check list to evaluate interior environment, targeting five Public Service Center facilities located in Gwangju Metropolitan city. This study investigated the Universal Design suitability of center interior Public Service Center on the basis of the tools for Universal Design check list which was composed of supportive design, adaptable design, communicability, safety-oriented design, and accessible design. Through theoretically considering the services of Gwangju's old city hall public service center, which got divided into common space, public service space, waiting space and informative material space. Evaluation on universal design application level showed that those with best universal design application are supportiveness and safety in public service space, communication efficacy and safety in waiting space and safety and accessibility in informative material space and acceptability in waiting space had the lowest application level.
