This study first introduces platform services and their business models. On the basis of the concepts of business ecosystem, we present a framework for distinguishing types of the platform service business models. Two key characteristics of business ecosystems-ecosystem configuration and value production process-are employed as fundamental dimensions for constructing typology. In particular, we also present the notion of value ecosystem, where not a single platform provider but a federation of platforms constitutes a virtual platform and completes a service system. The value ecosystem represents two distinct types of platform service business models : meta-platform ecosystem and platform coalition ecosystem. They show different governance structure in the platform federation and service flows across the ecosystem. We present detailed analyses of these two value ecosystems focusing on relevant cases of e-payment FinTech : Apple Pay as an example of meta-platform and Kakao Pay for platform coalition. Our conceptual typology contributes to platforms' proper strategy formulation and presents policy implications to, for example, platform neutrality.

A context-aware services platform supporting mobile agents consists of sensor nodes and a sensor coordinator. Sensor nodes collect environmental information and transmit the collected information to the sensor coordinator through wireless sensor networks. The sensor coordinator passes the information to the context-aware service module, and the mobile agent. The context-aware service module or the mobile agent performs services suitable for a user's situation based on the environmental information and a service actuation message is delivered to an actuation node through the sensor coordinator. In this paper, we present a context-aware services platform structure employed in our project, and describe context-aware services platform interfaces with a context-aware service module and mobile agents.

In this paper, we propose a connected car platform architecture called Mobile Second for developing of verity convergence services. A Mobile Second platform architecture is designed to provide more powerful and diverse convergence services for vehicles and drivers by applying technologies of Connected Car and ICT Convergence in various ways. The Mobile Second platform is implemented by applying Tizen IVI and Android to hardware platforms for IVI, Nexcom's VTC1010 and Freescale's i.MX6q/dl respectively. The Mobile Second platform provides the driver with the vehicle's information via IVI devices, mobile devices and PCs, etc., and provides Vehicle Selective Gateway(VSG) and Vehicle Control Framework for the driver to control his/her vehicle, and also provides a web framework to enable the use of VSG's APIs for the monitoring and controlling the vehicle information in various mobile environments as well as IVI devices. Since the Mobile Second platform aims to create new variety of services for Connected Car, it includes service frameworks for Smart Care / Self diagonostics, Mood & Entertainment services, and Runtime, libraries and APIs needed for the development of related applications. The libraries given by the Mobile Second Platform provides both a native library for native application support and a Java Script-based library for web application support, minimizing the dependency on the platform and contributing the convenience of developers at the same time.

In order for end-users in home networks to receive opportunities for useful services that go beyond legacy Internet Protocol TV (IPTV) services, this paper proposes a service platform that resides on the residential gateway (RG) for interworking between the home network and IPTV. This proposed service platform is called the home-oriented IPTV service platform (HISP) on the RG (HISP-RG). The proposed HISP-RG provides open architecture and functionalities to enable 3rd party IPTV service providers to locally and directly deliver home-oriented IPTV services to end-users in home networks. The HISP-RG can be an "add-on" and not a "built-in" solution for the existing standard RG. This paper introduces several home-oriented IPTV services that can be executed and delivered locally through the HISP-RG. Then, the open architecture and functionalities of the HISP-RG are defined and their requirements are specified. Finally, use cases of the HISP-RG for home-oriented IPTV services are presented.

Most important to financial institutions is to provide well designed and built services to the customers by accessing their core bank systems and affiliated systems in their partners. This will be essential to introduce new products and services and still be able to count on legacy and collaborative affiliated systems. Winning the war on such service competitions among financial institutions is attainable by seizing the "e-bank" opportunities in B2Bi and CRM (Customer Relationship Management). Such application integrations among systems and "e-bank" services need to be available in the new IT environment. In this article, an If and service architecture adopting unified e-business services platform is proposed. This architecture is able to achieve application integrations among legacy, affiliated, and e-business systems and services. We derive an architecture in unified e-business services platform by investigating current and future e-business services platforms involved in domestic and global international banks. Several financial interchange standards which are involved in B2B business of e-procurement, e-placement, e-payment are also investigated.

Currently, various technological models and services are emerging because of the development of information and communication technology and the convergence of industries. The ICT car field is expanding because of technological convergence in the automobile industry. However, ICT convergence services are still being developed based solely on technology; characterization of users and their needs is lacking. Therefore, two types of ICT car services that apply human-centered design processes are developed in this study. These processes create services and models while considering the quality and functions of products based on users (instead of technology) when developing products or services. Usability evaluation was performed on the developed services; a human-centered design process was applied to the results to confirm that the derived services resulted in high satisfaction. In the future, these research results will provide useful applications when developing ICT car services and strategies.
