Recently, many of organizations build up their performance measurement system (PMS) to measure their knowledge management performance. However, the system that doesn't well reflect the organization's strategies as well as surroundings could obstruct their performance improvement, instead. Therefore, It is really important to establish the PMS to reflect organization's surroundings and strategies. The purpose of this study is to make a diagnosis of a performance measurement practice of a domestic university's knowledge management. To serve this research purpose, we examine the uptight performance index and PMS from existing references. And we diagnose the specific practices and maturity rates of measuring performances, and the recognition of the performance index at "D" university recently adopting balanced scorecard to performance evaluation through the survey on academic affairs committee members, performance evaluation committee members, and administration members. The method analyzing data from the survey is a gap analysis which includes alignment analysis, congruence analysis, consensus analysis, and confusion analysis. We make a diagnosis of performance measurement practices at "D" university, raise several points of this performance measurement system, and present the improvement plans from these problems.

This paper describes a new method for performance improvement ultrasonic ranging system using V40 controller. Detectable range of ultrasonic ranging system depends on transducer frequency and bandwidth of the receiver, and damping of the transducer, etc. Conventional ranging systems are somewhat inaccurate because they do not have capability of compensating changes in medium condition. The novel ranging system overcomes this disadvantage by placing in the same medium a dummy sensor functioning as a standard calibrating instrument and by providing data processing capability using V40 controller.

In this paper, we analyzed the performance improvement of the DS-CDMA/dPSK cellular mobile communication system with CCI canceller and RAKE receiver techniques in mobile radio channel which is characterized by AWGN, Multi-user interference (mUI) and frequency-selective rayleigh fading. System capacity i.e., number of user per cell has been derived and the evaluated results are shown in figuraes as a function of PN code sequence length, number of RAKE receiver tap, BER and E$_{b}$/N$_{o}$. The voice activity factor is assumed to be 3/8 the number of sectors in a cell 3 and MUI is modeled as gaussian process. From the results, the capacity of the DS-CDMA/DPSK cellular mobile communication system is improved by adopting CCI canceller. When we adopt the RAKE receiver to mitigate the multipath fading, the error performance is improved and the amount of improvement is proportional ot the number of taps L in the case that each tap contains a signal component and the better of improvement can be obtained, the smaller of the SNR difference in each tap. The system capacity is more increased when the CCI canceller and the RAKE receiver is used in cascade.

The nuclear power Plant onsite AC electrical power sources are required to supply power to the engineering safety facility buses if the offsite power source is lost. Typically, Diesel Generators are used as the onsite power source. The 125 VAC buses are part of the onsite Class 1E AC and DC electrical power distribution system. The DC power distribution system ensure the availability of DC electrical power for system required to shutdown the reactor and maintain it in a safety condition after an anticipated operational occurrence or a postulated Design Base Accident. Recently, onsite DC power supply system trip occurs the loss of system function. To obtain the performance such as reliability and availability, we analyzed the cause of battery charger trip and described the improvement of DC power supply system reliability. Finally, we provide reliability performance criteria of charger in order to ensure the probabilistic goals for the safety of the nuclear power plants.

This paper covers a series of activities including initial proposal and actual development for the performance improvement of large-scale public facility management system under the application of green IT concept, which finally produced various excellent results in the administration of expense control, human resources, and general affairs. Actual development procedure starts from the analysis required by system users with the purpose of finding cost reduction opportunities under the application of green IT concept, which is followed by a series of activities including making a proposal for performance improvement, the development of trial system and the actual application into real system. As an example of large-scale public facility management system, national qualification management system was taken in order to convert the existing individual test storage unit into on-line storage space equipped with reinforced security function, resulting in acquisition of efficient productivity and greater savings in human resources as well as general expenses. A comparison with existing system and newly developed system was made in the area of number of operators, abnormal processing, system maintenances. It proved that efficiency increased to the minimum of 2 times and to the maximum 12 times with the 5 million savings of personal storage unit.

The national R&D project is a major strategy for the development of science and technology in the country. This is promoted for the purpose of improving the welfare of the people, such as creating jobs and fostering small and medium-sized enterprises, through the results of science and technology research conducted with support from the national budget. Therefore, analysis of the performance evaluation and budgeting system of the current national R&D project is one of the essential parts of preparing a system improvement plan. This study derived improvement plans through a comparative analysis of national R&D project performance evaluation and budget systems in Korea and leading countries such as the United States and Japan. As a result, it was confirmed that it may be difficult to derive innovative research results due to the lack of sustainability and a short period of time to require quantitative performance. To overcome these difficulties, the need for system improvement as follows was suggested. First, it is necessary to enlarge and prolong national R&D projects. Second, a plan for securing sustainability is needed in consideration of the main characteristics of each research field. Finally, it is necessary to strengthen the linkage between organizations in charge of national R&D projects. And also, there is a need for a system that can continuously identify problems and improve the system. In addition, the constitutional amendment will be necessary to separate science and technology from economic development, which states that Article 127, Paragraph 1, "Science and technology should be subordinated to economic development," which is the science and technology article of the current constitution.

In this paper, we have considered the performance improvement of Multi-Carrier DS-CDMA system using hybrid SC/MRC-Lc/L diversity receiving technique over multipath fading environment and compared with that of a Wideband DS-CDMA system. In the result, the PBI has caused a performance deterioration over partial bandwidth in Multi-Carrier DS-CDMA system. Also, Multi-Carrier DS-CDMA system using Hybrid SC/MRC-Lc/L diversity received can determined the complexity and the performance vs the expenses for the system that select the number of input branches.

Recently the construction of high-rise reinforced concrete building is progressively increased as the social demands. It is significantly important factors such as economy, the safety of structure, and the flexibility of internal space. Therefore new structural system is also required to be attained the reduction of story height, the flexibility and efficient use of space. The most suitable structural system is with the economy and flexibility, flat plate slab system in high-rise reinforced concrete building. In this research, it was focused in the improvement of shear performance in the flat plate system using high ductile fiber reinforced mortar. It was evaluated the shear performance in the critical region of slab-column connection. The flat plate system, designed by the high performance and safety, was developed as a new technique in the application of high-rise R/C building.
