  • Today, although most bluetooth hands-free devices within a vehicle provide telephone service functions such as voice communication, caller id display and SMS message display and so on, they do not provide a function that displays Internet-based text data. We need to develop a scheme that displays the internet-based text data including existing hands-free function because the request for using the Internet service is increasing within a vehicle recently. The proposed bluetooth device application includes advanced function such as SNS message arrival notification, the message display function and we chose Android as the implementation mobile platform giving consideration to the fact that most SNS applications operate on Android and the platform is easily embedded into small embedded device. Smartphone or tablet PC connected with the proposed bluetooth device is an Android-based device and we designed a form of Android app for the function implementation of the devices. When the audio-text gateway app receives SNS text data, it extracts title and sender information from the message header information in a form of text data and sends them via ACL (Asynchronous Connection-Oriented) link to the bluetooth device showing the data on the screen. Android-based bluetooth devices are not possible to play voice through speaker because the bluetooth hands-free or headset profile ported within Android platform normally only includes audio gateway's function. The proposed bluetooth device application, therefore, applies the streaming scheme that sends data via ACL link instead of the way that sending them via SCO (Synchronous Connection-Oriented) link.

  • This paper defines a diagram showing the characteristics of service connections in SOA, and it designs the connection testing with the diagram. The detail steps of building test requirements in the test design phase are explained, and the steps are applied to two different enterprise cases as examples. The cases are real SOA system of real enterprises. Recently, many enterprises have been trying to reconfigure their system as SOA systems. However, these projects are hard to be applied to their mission-critical real systems, since there is few testing technique understanding SOA characteristics, One of the missing characteristics of SOA in testing is that SOA needs a layering systems between business processes and applications. This paper focuses on the layering system of SOA to solve the testing problem in SOA.

  • This study takes note on the need for the consideration of the relationship between the service contents and service space which libraries provide, since at the moment the demands of library users, purpose of using it, etc. gradually become varied. In this study, type classification of public libraries was done focused on the relationship between service contents and service space, targeting Japanese public libraries. Through linking approach between service contents and service space, the analysis of Japanese public libraries' characteristics and type characteristics could be captured. This study has ultimately aimed to prepare for the basic data which will help Korean public libraries to make connection between service contents and service space in the future. The collected service contents and service space had been analyzed by multi-dimensional data analysis methods such as the "Quantification Theory Analysis Type III" and "Cluster Analysis". After characters of libraries were analyzed, the findings of this study show the views such as "the field of information provided, the method of information provision, and the object of service provision." And types of 44 libraries are classified into those which have 6 kinds of characteristics as follows : (1) group-oriented libraries which provide the jobs and employment information, (2) libraries which provide the jobs and employment information through the counselling space, (3) individual-oriented libraries which provide the information of education-related fields, (4) group-oriented libraries which provide the information of education-related fields, (5) libraries which provide information focusing on the counselling space, (6) individual-oriented libraries which focused on the service provision.

  • In order to implement e-trade infrastructure through the radical innovation of trade process, e-trade platform which is called 'uTradehub' has been developed for three years. After pilot operation of this platform in 2007, the formal service of e-trade such as logistics, customs and foreign exchanges had been provided in 2008. However, the usage of e-Trade platform is not the level of users' satisfaction because trade-related communities have not actively participated into e-trade platform and several functions with users requirements are necessary to develop additionally. In this regard, there are strong demands to suggest some strategies for application and usage proliferation of e-trade platform. Therefore, this paper would like to evaluate the current status of e-trade platform service and usage by the theoretical consideration of preceding researches and practical analysis of statistical data. Then, it will explore several service improvement ideas in terms of system supplementation and integration, electronic documents standardization, radical change of using fee, global connection, user oriented education and advertisement.

  • In highly dynamic IoT environments, the connection statuses of IoT resources and the availability of IoT-based services change frequently. Therefore, to successfully build distributed service registries for managing and finding the information about available services in an effective manner, it is crucial to minimize the overhead of message exchanges between registries and to reduce the time overhead for identifying the capabilities of available IoT resources and the services that can be provided by utilizing these capabilities. In this paper, we propose a lightweight messaging approach that uses hierarchical Bloom filters to efficiently represent service information to be exchanged and managed by distributed service registries for IoT environments with high mobility. We also propose a method for serializing the dimensions of a Bloom-filter-encoded search space. We conducted experiments to demonstrate the improvement in the service discovery performance, the reduction in message traffic among service registries, and the decrease in the latency when synchronizing distributed service registries.

  • From middle of 90's, SCM had emphasized the importance of connection of all companies which participate to a market, and outsourcing has emphasizes the slim structure of companies for pursing cost reduction and service improvement. But outsourcing as '2-1=1' and integration as '1+1=2' not adapt to the advanced market but return to the former state. Besides, it is impossible of subcontractors and logistics companies to execute these strategies which are win-win strategy and outsourcing. So many logistics companies have sharp competition in price recently. Therefore logistics companies have increased the need for a profitable business model and strategy. This paper researches the limitations of logistics market and redefines the role of logistics through the evolution of logistics. Also this paper proposes new role(Logister) and structure(Velcro structure) for not maker-oriented logistics but market-oriented logistics. The introductory case study will help to understand 2 terms(logister and velcro structure).

  • TTCN(Tree and Tabular Combined Notation), as an international standard, provides a concept and notation to describe a protocol test specification. In this paper, we explain some considerations on each components of Abstract Test Suite and propose naming conventions for Constraints and Test Cases based on the experience of describing Test Suite for real protocol. We also analyze some problems on real application of Test Suite and propose an approach to avoiding such problems in the stage of Test Suite specification. In this paper, we use the SSCOP(Service Specific Connection Oriented Protocol) protocol, that is a sub-layer of ATM Forum UNI 3.1 protocol stack, as an example to proposals on naming conventions on Constraints and Test Cases.
