  • Along with the growth of u-Healthcare, we propose a security enhancement based on network separation for CloudHIS with for handling healthcare information to cope with cyber attack. To protect against all security threats and to establish clear data security policies, we apply desktop computing servers to cloud computing services for CloudHIS. Use two PCs with a hypervisor architecture to apply physical network isolation and select the network using KVM switched controller. The other is a logical network separation using one PC with two OSs, but the network is divided through virtualization. Physical network separation is the physical connection of a PC to each network to block the access path from both the Internet and the business network. The proposed system is an independent desktop used to access an intranet or the Internet through server virtualization technology on a user's physical desktop computer. We can implement an adaptive solution to prevent hacking by configuring the CloudHIS, a cloud system that handles medical hospital information, through network separation for handling security enhancement.

  • The Mobile device like smart phone is a small computing device and easy to carry around. The Mobile devices are wildly being used as desktop personal computer and can served individual services. Because of compatibility of applications working on mobile devices are not good, so developer need to develop it that match changes in platform fetures. In this paper, we design and implementate ubiquitous healthcare monitoring system that can be runs on many different platforms using HTML5 as a standard web development language and jQuery as a javascript library. Ubiquitous healthcare monitoring system is runs on on many different platforms like mobile platforms and desktop web browsers.

  • We present a novel watercolor painting drawing system which can work even on low powered computing machine such as tablet PC. Most digital watercolor systems are generated to perform on desktop, not low powered mobile computing system such as iPad. Our system can be utilized for art education besides professional painters. Our system is not a naïve imitation of real watercolor painting, but handles with properties of watercolor such as diffusion, boundary salience, and mixing of water and pigment.

  • A remote measurement system for nerve conduction has been developed to aid patients with spinal cord injury by accident. Existing cooperation between rescuers and doctors can be supported through the introduction of multimedia desktop video conferencing. Such facilities provide several advantages over conventional video conferencing. In particular, patients may feel free because they can see a doctor through the video conferencing facilities. This paper describes the system implementation and evaluation. The author considers the network capability and image data handling, and introduces a method a transmit image data for this system.

  • As to the recent advances in computer technologies and high-speed networks, telecommunication services and provision of multimedia services will be provided on the basic of a new software architecture adapting networking infrastructure on open information networking architecture. In this paper, the video conference services has been selected as a target service example because it is expected to become one of the most important services on the full service network. In fact, it can be viewed as the basis for providing telecommunication services such as video telephony and video conferencing. This paper presents the prototyping of TINA (Telecommunication Information Networking Architecture) based desktop video conference system using the concepts of session management. The prototyping of desktop video conference system aims at assessing TINA concepts and refinement of the mapping between session graph and connection graph, and provides object modeling methodologies towards distribution and objected-orientation.

  • we can define the procedure of Authoring that it makes area cord and the reproduction prevent menu programmed into MPEG II video stream , Audio which is AC-3 audio stream and subtitle under its own category. And it makes process an attribute, an order and an operation, gives the last disk image (DVD). There are various types of Authoring tools in the market so that authoring tools can enable, encourage, and assist users ('authors') in the selection of tools that produce simple title and video production and editing suites. In this paper, we will compare and analyze authoring process in which image and sound are captured into DVD creation with IEEE 1394port with regard to Window system using generally with Desktop PC and the Macintosh of the PC on the system of Windows and OSX.

  • A PDA is used mainly for downloading data from a stationary server such as a desktop PC in an infrastructure network based on wireless LAN. Thus, the overall performance depends heavily on the performance of such downloading with PDA. Unfortunately, for a PDA the time taken to receive data from a PC is longer than the time taken to send it by 53%. Thus, we measured and analyzed all possible factors that could cause the receiving time of a PDA to be delayed with a test bed system. There are crucial factors: the TCP window size, file access time of a PDA, and the inter-packet delay that affects the receiving time of a PDA. The window size of a PDA during the downstream is reduced dramatically to 686 bytes from 32,581 bytes. In addition, because flash memory is embedded into a PDA, writing data into the flash memory takes twice as long as reading the data from it. To alleviate these, we propose three distinct remedies: First, in order to keep the window size at a sender constant, both the size of a socket send buffer for a desktop PC and the size of a socket receive buffer for a PDA should be increased. Second, to shorten its internal file access time, the size of an application buffer implemented in an application should be doubled. Finally, the inter-packet delay of a PDA and a desktop PC at the application layer should be adjusted asymmetrically to lower the traffic bottleneck between these heterogeneous terminals.

  • With the explosive proliferation of smart devices that may be connected to the fast Internet, virtual desktop interfaces(VDI) are being implemented in enterprises allowing employees to work anywhere anytime in the same technological environment. As this kind of systems are intended to raise the work performance, a research model is constructed from the review of research literature on service quality and work design. The model consists of VDI system service quality (ubiquity, availability, compatibility, security and ease of use), system satisfaction, task performance and job satisfaction. As VDI is designed as a support system for cooperative work, the task interdependence adopted from the work design theory is postulated here as moderating the effect of user satisfaction on task performance and job satisfaction. 147 data points were collected by a survey of VDI users in a global firm and subjected to PLS analysis. Interestingly, ubiquity and compatibility seem to be not statistically significant for user satisfaction while availability, security and ease of use of VDI system are statistically significant. Task interdependence is found to be a relatively strong mediator between system user satisfaction and task performance, however, interestingly, the coefficient come out as negative. This may indicate that the influence of VDI user satisfaction on task performance would not be high in highly interdependent tasks. Considering that VDI is intended for supporting 'interdependence' in cooperative work, this finding is a bit surprising. In-depth discussions are made in the discussion followed by future research directions.

  • In the conventional desktop PC environment, keyboard and mouse are used to process the user input and monitor displays the visual information as an output device. In order to manipulate the digital information, we move the virtual cursor to select the desired graphical icon on the monitor The cursor represents the relative motion of the physical mouse on the desk. This desktop metaphor does not provide intuitive interface through human sensation. In this paper, we introduce a novel tangible interface which allows the user to interact with computers using a physical tool called "Smartpuck". SmartPuck system bridges the gap between analog perception and response in human being and digital information on the computer. The system consists of table display based on a PDP, SmartPuck equipped with rotational part and button for the user's intuitive and tactile input, and a sensing system to track the position of SmartPuck. Finally, we will show examples working with the system.
