This study analyzed the effects of smart phone using for business on work performance in the field. We classified functional and practical aspects of smart phone affecting employee's work performance through former studies. As independent variables, we selected portability of equipment, rapidity of information and ease of use for functional side, and selected fit to work and subjective norms for practical side. And dependent variable was work performance. We also suggested that innovation resistance would be a moderator. The results showed that the effect of work performance was influenced by portability of equipment and fit to work. However, hypotheses on moderating effects of innovation resistance were not supported. This study made a discrimination in terms of an application phase of smart phone as against former studies. The results of this study will provide practical implications for related enterprises in the field to develop ways of using smart phone as an effective strategy.

The network configuration of SMS number moving service is a very important factor to improve the user convenience to Internet Telephone. To provide the service, The SMSC system is required the the function of DB process and management of the subscriber, In case of SMSG system to interconnects with the other network and SMSC, the function of the call processing of subscriber who has changed his number by interconnecting with NPDB(Number Portability DB) is required. This paper had studied the way to consist the efficient network by the number moving technique.

This study is The Effect of the on the purchase behavior of the Software Quality. To have purchased the software in a Consumer surveys were conducted. The following is a summary of results of this research. First, the software quality and significant consumer purchasing behavior (+) of influence. Functionality, usability, portability of software quality attributes the impulse buying and buy more of both the (+) showed the influence. Second, software quality is urge consumers to purchase significant (+) of influence. Functionality, reliability, usability, portability of software quality (+) showed the influence. Third, the software quality In the consumer buy more significant Chung (+) showed the influence. Software quality, functionality, usability, portability name (+) influence. In conclusion, the quality of the software in consumer purchasing behavior (+) were of significant influence. In particular, factors that functionality, usability factors, portability factor in the relatively large influence on the purchasing behavior. Software technology development, planning, development, testing, and in each step must keep in mind the following. First, the software, when used in certain conditions, Inherent ability to meet the needs and requirements set forth to provide the appropriate functionality and accuracy as the ability of software products each other with the capabilities to the effective and thorough security features should be required. Second, software, a user-specified criteria to use in understanding and learning, and must, and the ability to prefer. Software for users to understand and easy to use, whether the check. In particular, understanding the interface, Help understanding, understand the input and output data, and interface consistency, the user information, the message must be equipped and easy to understand. In addition, ease of learning to be self-learning, and help ease of access shall be required. Third, in certain circumstances, a different environment to transfer be equipped with the functionality of the software. Applying data structures and application environment, helping transplant convenience must keep in mind sex.

In a large scale parallel computation, failures of some nodes or communication links end up with waste of computing resources, Several fault-tolerant MPI libraries have been proposed so far, but the programs written by using such libraries have a portability problem since fault-tolerant features are not supported by the MPI standard yet, In this paper, we propose an application-level fault-tolerant linear system solver that uses the asynchronous iteration algorithm and the standard MPI functions only, which does not have a portability problem and is more efficient by adopting a simplified recovery mechanism.

The telecommunications market in European Union was fully liberalized as schedule except some member countries on and after January 1, 1998. The full liberalization of telecommunications market which will provide lower charges and various services to consumers. At present, the monopoly on voice telephony services is being maintained in five member countries authorized the implementation delay of liberalization. There are still remain many problems, such as pre-selection of carriers, number portability and interconnection, to solve by January 1, 2000. After examining the basic principle of telecommunication regulations and the liberalization trends of EU countries, we review the future assignments and prospects of European Union. finally we suggest implications for telecommunication policy and carriers in Korea.

Software reusability is one of key factors which impacts cost and schedule on a software development project. It is very crucial also in satellite simulator development since there are many commercial simulator models related to satellite and dynamics. If these models can be used in another simulator platform, great deal of confidence and cost/schedule reduction would be achieved. Simulation model portability (SMP) is maintained by European Space Agency and many models compatible with SMP/simulation model interface (SMI) are available. Korea Aerospace Research Institute (KARI) is developing hardware abstraction layer (HAL) supported satellite simulator to verify on-board software of satellite. From above reasons, KARI wants to port these SMI compatible models to the HAL supported satellite simulator. To port these SMI compatible models to the HAL supported satellite simulator, simulation scheduler is preliminary designed according to the SMI standard.

This paper, proposes concept of personal robot middleware core also called streaming layer. Based on openness and portability, the streaming layer is proposed in order to meet requirements of different kinds of applications. The streaming layer architecture provides effective management of data flows and allows integration of different systems with ease regardless software of hardware platform. With extensibility support additional features can be build in without affect to performance. Therefore, heterogeneous network support, real-time communications, embedded boards support can be easily achieved. In order to achieve high performance together with portability into different platforms, the most functions has to be implemented in C language, while critical parts, such as scheduling, priority assignment has to be made using native functions of tested platforms.
