Purpose: The purpose of this study is to propose useful idea and data by association analyzing MRA results of defense research and development. Methods: The collected data through the DTaQ MRA system are analyzed using three association analysis measurements. Results: The results of this study are as follows; some evaluation items are very highly associated according to confidence and lift. The result is also meaningful as contents of evaluation items. The result of this study suggests a direction for improvement of MRA system. Conclusion: Some evaluation items of MRA are meaningfully associated. Therefore, the result can support the improvement of MRA system.

In Korea, EMS Fund Operation seems to move the opposite direction to right way. The most initial EMS fund was consumed loan for some emergency patients without any particular results. Since 2002, the use of EMS fund also has shown a tendency to shift one side. By the results, it was 44.3% to support emergency medical centers, so called hospital EMS system and 28.4% to purchase ambulances and helicopters, and 1.6% to operate Central Medical Center, prehospital base in the EMS fund consumed in 2004. It was never supported for the environmental improvement and development of universities, colleges, and private EMS units having the primary responsibilities. The initial EMS fund using should be used for prehospital base, e.g., prehospital staffs, communications, and facilities and balanced development between public and private EMS units than any other fund using.

Since micropiles were conceived in Italy in the early 1950s, which have been widely used for In-situ reinforcement, bearing pile or the concept of combination in the world-wide. The meaning of micropiles usually differs from that of a general deep foundation. Because the load capacity of it was mainly affected by skin friction. Also, it could be obtained the improvement effects of load capacity or ground's rigidity by the unitary behavior of ground and micropiles. In this study, The model tests were peformed on the dense sand where micropiles are set to the vertical direction. Strip footing was used in it. Steel bars of dia. 2 and 4㎜ were used in model tests of which the sand was attached on the surface, and the length of it was changed as 2B to 6B(where, B is width of strip footing) Through this process, the load capacity were analyzed from the test results in the relationship between load and displacement.

In this paper, we present the AFP(antenna front plate)s which were designed to reduce the reflection for the sake of the improvement of DF(direction finding) accuracy. The AFP consists of front plate, absorber and radome. The AFPs were optimized respectively by real test and we performed the DF test using our AFPs in laboratory. The DF test shows that the DF accuracy is about 2 times better than the requirement capability. Then, the DF field test was executed using the AFPs, which were installed in helicopter in consideration of the reflection by platform. The result of the DF field test is superior to the requirement capability also, which shows the validity of our design method.

Construction safety should be considered prior to any other factors to execute construction projects smoothly and reduce the social expenses. Especially, the safety education is very important to the lives of labors and to control the four resources such as time, money, quality and safety. On this research, the present situation and related regulations of safety education are reviewed and the education contents and realities of the safety empirical education places are surveyed. Also questionnaire to education lecturers is performed to understand the satisfaction level of the education programs of the education places. Finally, the improvement directions are suggested to inspire trainees based on the results of the research.

Switching to organic farming practices in agricultural production reaches the end of the period it takes an average of five years. During this period, agricultural soil management to improve the investment must be sustained. Results of the survey of environment-friendly agricultural lease rates appear to approximately 54.2% lower than agricultural practices. Environmentally friendly agricultural land is leased on a long transition period of the contract cost, many buried incompleteness, uncertainty of contract fulfillment(opportunistic behavior) occurs when the transaction costs. This ultimately can hinder the spread of organic farming. Thus, the qualitative development of organic farming and land leasing in order to minimize transaction costs, should that occur. The alternative 'cooperative long-term lease contract' is a system.

The heavy equipment such as tracter has been studied to improve rather the performance of engine than comfort. The mufflers of tracters have various specifications according to their uses. The exact analysis of various mufflers is needed to reduce the level of exhaust moise, a major noise source of engine, to improve the ride quality of tracter. In this study, a software based on Green's function is developed to predict the performance of sound transmission loss for a muffler according to the locations of inlet/outlet pipes. The locations of inlet and outlet pipes can be fixed at different position individually. The conventional muffler has the locations of inlet/outlet pipes on the direction of longitudinal axes. On other hand, the inlet and outlet pipes may be located at the circumferential surface of a test muffler such as one of tracter. The software is verified by analysis and experiment on current muffler of tracter and the improvement technique is proposed to reduce the level of exhaust noise.

Currently the industrialization, the urbanization, and the phenomenon of nuclear family is mainstream of korean society. And our country enter into an aging society, on the contrary. The concept of support for aged person is dwindled away. The main reason can be summarized as the aged person's consciousness and the family's economical burden. So, the concern about the facility for the aged person has being issued as a necessary factor to be considered by public. Therefore. the problems of the facility were analyzed and the improvement direction for them were suggested in this study.

Business information system should utilize the provided various information services from information resources： namely, the improvement of business information can be achieved by the establishment of an business information center and by the employment of qualified librarians. Therefore. employers may get effective management and operation on theirs business when their adoption of innovative technologies, management strategies and information services are combined together. Especially, the information services they can get through Internet. prompt decision making adoption of new policies, flexible organization of business management and innovation of technology will be the core factors.

Keeping the polarization direction of the projection light unchanged is of crucial importance for high quality of images on a double-screen 3D projection display system. It has been found that the deposition of oxide layers on the surfaces of scattering polarizer film results in an improvement of polarization maintenance property of the film. The secondary image formed on the front screen by the light scattered from the rear screen decreases by 30% through the application of oxide layers on both surfaces of the screen. Since the oxide layer can also be used as an anti-reflection (AR) coating of the film, this method is very effective for the projection display applications.
