Medical Gateway(MG), that integrates medical devices with its unique data format in various hospital information systems, provides effectiveness in the cost of the management unlike existing systems that uses PC as a gateway to hospital information systems because MG enables to interface medical devices with itself. However, in spite of using MG for integrating medical devices, we need additional programs or systems to interwork with EMR system of each hospital in accordance with the configuration of DB. In this paper, we design and implement the format of medical information and server system for interworking MG with EMR system. The proposed system makes easy exchanging medical data between MG and EMR system. Thus, the proposed system can contribute to a national project to export abroad advanced hospital setup converged with IT.

Hand posture recognition is an important technique to enable a natural and familiar interface in HCI(human computer interaction) field. In this paper, we introduce a hand posture recognition method by using a depth camera. Moreover, the hand posture recognition method is incorporated with MPEG-U based advanced user interaction (AUI) interface system, which can provide a natural interface with a variety of devices. The proposed method initially detects positions and lengths of all fingers opened and then it recognizes hand posture from pose of one or two hands and the number of fingers folded when user takes a gesture representing a pattern of AUI data format specified in the MPEG-U part 2. The AUI interface system represents user's hand posture as compliant MPEG-U schema structure. Experimental results show performance of the hand posture recognition and it is verified that the AUI interface system is compatible with the MPEG-U standard.

In this paper, we propose a monitoring method of smartphone to integrate IoT technology to monitor the state of the vehicle for fault diagnosis of E-Mobility power converter. In China, EV regulations are being implemented to promote technological development and market changes in electric vehicles. To meet this trend, E-Mobility should study suitable monitoring technology. The OBD-II method used in existing automobiles is a wired / wireless communication method. In order to apply it to E-Mobility, additional interface and communication link are required. In this paper, we propose a technology to monitor the status information of power converter for E-Mobility by combining existing technology with IoT. This technology simplifies the existing network protocol and hardware interface, and confirms that the E-Mobility power converter and smartphone can be interworked for easy user monitoring. And we have done research to make high value product design from the aspect of function.

By adding short-range wireless communication function such as Bluetooth and Wi-Fi to the last vehicle in conjunction with a smart phone, a modern automobile is becoming entertainment screen to determine a variety of information such as car location information, diagnosis information, etc. through the ECU vehicle electronic control unit. In this study, by utilizing short-range communications capability of the on-board diagnostic devices and smart phones in association with the on-board diagnostics, compatibility tests among a number of smart phone models, Bluetooth and NFC(Near Field Communication) were carried out and those results were analyzed. Furthermore, composition of on-board diagnostic device having Bluetooth and NFC interface function and the fault diagnosis function were implemented, and fault diagnosis debugging program was developed. In addition, fault diagnosis data of the vehicle via the OBD-II interface was extracted. Finally, the on-board diagnostics CAN Protocol implementation has been proposed, and the results of work was analyzed.

Recently, new computing technologies are emerging from various life environments, as a result of the spread of network environments and the advent of new computing devices. This trend in computing technology is called "Ubiquitous computing" and is being developed to provide a convenient lifestyle through the dynamic integration of physical objects and digital information. The hybrid tag interface suggested in this paper is a usage model that integrates widely used image codes and recently applied RFIDs in various applications. On the basis of this concept, we eventually designed five different models such as Dual, Partial, Relative, Rebind and Discrete types according to their interrelation. In this paper, the characteristics of tag interfaces in the form of image codes and RFIDs are analyzed and the hybrid tag interface is proposed here for more efficient and convenient interface.

AUI(Advanced User Interaction) interface aims to enhance interaction between various input/output devices and scene descriptions represented by video, audio, and graphic. Recently, MPEG-U part 2 standardization for the AUI interface is under development by MPEG(moving picture experts group). This paper introduces MPEG-U part 2 standard and presents MPEG-U part 2 AUI interface system. The AUI interface system consists of user interface in/output modules and MPEG-U XML generation/interpretation modules. The former and the latter are for UID data handling and XML data processing, respectively. This system MPEG-U standards-based input/output devices and to improve the interaction with the user can be used as a framework. By implementation of the proposed AUI interface system, MPEG-U usage scenario is introduced and it is verified that the AUI interface system conforms to MPEG-U standard.

Defense M&S software industry has carried out a variety of studies related to an efficient implementation of large-scale simulation and interoperability with respect to each of the system and HLA has been developed to provide a common architecture for distributed simulation of them. HLA defines Federate interface specification and provides services through RTI. Meanwhile, the difficulty lies in developing the software based HLA. Federate developer needs to understand how to handle Metadata produced RTI and has to modify the interface code whenever FDD is modified. This paper presents the implementation method of SOM interface using the code generation technique and middleware architecture for providing simple API. It solves the problem for implementing the framework of distributed object communication by using proposed method.

Recently, with the development of mobile communication technologies such as 5G, interest in oscilloscope technology based on high bandwidth and user-friendly UI is increasing. In this paper, we proposed a Python-based UI(user interface) SW for a high-bandwidth digital oscilloscope in connection with the study of a 13GHz band digital oscilloscope system. The proposed UI SW is designed not only to be executed integrally with the oscilloscope, but also to be run on a separate PC or laptop cooperating with the instrument through WiFi communication. Functions of the UI SW consists of displaying and analyzing signal data, storing signal data in an external storage device, generating test signal data, and reconfiguring the toolbar. Finally, we have shown that the proposed digital oscilloscope system operates normally by interworking test with the signal generator.
