The development of wireless communication MAC layer is usually released as SoC which is a combination in hardware and software. In this system development environment, an environment for software development and verification is necessary because the hardware development takes a lot of time priori to completion. In integrated development of hardware and software, simulation environment of hardware and software provided by hardware modeling using HDL at RTL and ISS respectively. By increasing the development complexity of system, ESL design modeling systems at higher abstraction level than RTL has already prompted. The ESL design is divided untime model and time model. This paper present design and implementation of MCU for untime model simulation, not time model. Proposed MCU can optimize the system at early step of system development and move up the development completion time by verifying the system function easily and rapidly than part required exact time in untime model. In this paper, we present an MCU module based on SystemC and UC/OS-II Module providing real-time operate system.

Interested in the importance of Consumer Education in school has recognized in modem society, due mainly to the development and change of consumption life. Among the many contributions to the study of consumer issues that Consumer Education in school is the most important thing to be rational consumer. However, There is no any system to support the Consumer Education in school even though we need it. And thus, this paper is used the method of Contents Analysis through critically reviewing the professional web-sites of Consumer Education Center in Japan and Europe in order to investigate what the goal is, what contents are, how they operate their Consumer Education System. Moreover, we compare two web-sites in aspects of system, structure. The Consumer Education in Japan and Europe is toward the value of life which is not the buy-man-ship but the way of thinking and philosophy of life. The school lead the Consumer Education through the integrated system which is invoked all of related subjects. Each related subject is gotten together for the Consumer Education. Most of all the Consumer Education Center in Japan and Europe is in the middle of Consumer Education in school, and then absolutely assist and support Consumer Education in school.

Recently, users' demands for multimedia service are increasing. But, server systems offer inefficient multimedia data service to users. In this paper, to transport multimedia data in the server system more efficiently, we propose the SRTPIO(Special RTP Input/Output) module that process the RTP(Real-time Transport Protocol) data in the kernel with the SIO(Special Input/Output) Mechanism. The SIO mechanism improve a transfer speed because it reduces overheads associated with data copying and context-switching between the user mode and the kernel mode occured in general server system in the kernel-level. The SRTPIO module, integrating the SIO mechanism and the RTP data processing in the kernel, support efficient multimedia data transfer architecture.

Database system benchmarks, which are usually evaluated to use the maximized resource in order to get the best results, arc not likely to simulate the real environment. We propose a workload generator that helps benchmarks be executed in the environment similar to a real world. The workload generator can create memory-bound, CPU-bound, and I/O-bound workloads. The workload generator allows users to create an integrated workload. which is similar to a real workload users run across in practice. Finally, we conducted the experiments that the Wisconsin benchmark was performed with the TPC-C and with the workload generation tool, and showed the feasibility of the proposed workload gen-eration tool comparing with two experimental results.

This study is to analyze and interpretate strategies and managing behaviors in order to propel village mini-library movement in Korea from the starting year of the village mini-library to 1980. The strategies conducted for propelling the movement can be divided into two: one is the strategies, as an output goal, related to establishing and managing mini-library; the other the strategies, as a support goal, related to carrying out the movement procedures. Therefore, the study is to examine the two strategies individually using by the qualitative research method such as analyzing related historical records and literatures, interviewing the persons concerned. and organizing the author’s experience.

This study aims to investigate the current status of the operation system of the curriculum support extra-curricular program, focusing on the extra-curricular program operation system of other universities, and suggest the desirable operation system and performance management plan of the extra-curricular program in cultural education. To this end, the analysis of the extra-curricular program operation system of eight four-year universities in the Seoul metropolitan area was conducted on the existence of core competencies, computer systems and extra curricula program guides, credit-linked and mileage scholarship programs, and the analysis focused on the characteristics, merits and demerits of each university's operating system. It was also intended to propose the desirable operation system and performance management plan of the extra curricula program in liberal arts education, focusing on the operation system of the extra curricula program of E University and the corresponding performance management. Conclusion To operate the extra curricula program efficiently, the computer system and the extra curricula program guide, credit link and mileage scholarship system should be introduced. In addition, the analysis of the operation system of the curriculum support program of E University shows that E University operates systematically with the direction of operation of the core competency-based curriculum support extra-curricular program, and the performance management of the extra curricula program of E University is carried out through the EU-TQM System Integrated Management System.

Today in Korea, various types of B2B or B2C businesses are carried out on the Internet and the catalog information is the molt important factor to make customers purchase the product. However, no case can be found where information is shared between the business partners, more specifically, each catalog supplier possesses data that are incompatible with others. Though the e-business market has rapidly expanded, it is still difficult for businesses to attract buyers unless an integrated system is provided for more fast and convenient B2B businesses. Such a systematic and integrated catalog system is highly demanded along with current database management system Therefore, this study suggests the E-Catalog system consists of a fixed and standardized catalog system offering product information and a network-based architecture offering products to customers through a search system. The proposed system also supports CRM (Customer Relation Management).

From a software engineering point of view, tracing is a special form of logging that records program execution information. Tracers using dedicated hardware are often used because of the characteristics of tracers that need to generate and decode huge amounts of data in real time. Intel(R) PT uses proprietary hardware to record all information about software execution on each hardware thread. When the software execution is completed, the PT can process the trace data of the software and reconstruct the correct program flow. The hardware trace program can be integrated into the operating system, but in the case of the window system, the integration is not tight due to problems such as the kernel opening. Also, it is possible to trace only a single process and not provide a way to trace multiple process streams. In this paper, we propose a method to extend existing PT trace program to support multi - process stream traceability in Windows environment in order to overcome these disadvantages.

In this study, I researched, analysed and compared the examples of civilian maritime search and rescue auxiliaries of world leading countries' such as Japan and America, and the Korean volunteer fire fighting team. Through this, I suggest that the decentralized civilian maritime search and rescue forces of Maritime Rescue and Salvage Association and KCG Civilian Auxiliary should be united into unified search and rescue system and establish legal basis for stabilized support and development. It seem that we should organize laws and regulations for the government to have centralized control of rescue mission as in the cases of America and Canada and elivate rescue mission capability with systemized education and training entrusted to specialized external training organization. I proposed to establish financial support such as fund for the stabilized status of civilian auxiliary, domestic and overseas training session for the civilian auxiliary to inspire integrity and sense of duty as a part of maritime search and rescue forces.

Humanities and social sciences researchers and database experts have teamed up to build a database of IPR materials prepared by the Institute of Pacific Relations (IPR). This paper presents the issues and solutions inherent in the database construction for ensuring the quality of IPR materials. For the accessibility of the database, we maintain the database on the Web so that researchers can access it via web browsers; for the convenience of the database construction, we provide an integrated interface that allows researchers to perform all tasks in it; for the completeness of IPR materials constructed, we support the responsible input and the responsible approval that identify responsibilities of each IPR material entered; and for the immediacy of the approval, we support an interactive approval process facilitating the input of researchers. We also use database design, query processing, transaction management, and search and sorting techniques to ensure the correctness of IPR materials entered. In particular, through concurrency control using existence dependency relationships between records, we ensure the correctness between the operating system files and their paths. Our future studies include content search, database download and upload, and copyright related work on IPR materials.
