TEEE(Thermoplastic ether-ester elastomer) is expected to reduce the noise and vibration from railway because its unique properties such as porosity. in this study, after building TEEE rail pad at established rail, we conducted practical test and vibration test to inquire the field application and endurance of TEEE material. The test results showed that TEEE material was lower vibration than EVA material, therefore, TEEE material was effective from a vibration reduction point of view.

One solution to the estimation of product reliability during the development phase is to measure reliability improvement over time and compare this improvement to previous product development progress. This paper presents the reliability growth theory and applies it to some subsystems of vehicles during their design, development and prototype testing. The data presented illustrates explicitly the prediction of the reliability growth in the product development cycle. The application of these techniques is a part of the product assurance function that plays an important role in product reliability improvement.

Ferrite plating enables were grown by ferrite by plating method in solution at low temperature(<10$0^{\circ}C$). This faciltates the fabrication of new ferrite thin film devices using non- heat-resistant materials(plastic, GaAs ect) as substrates. Combining the ferrite plating with sonochemistry, application of power ultrasonic waves to stimulate chemical reactions, the crystallinity and qualities of films were improved. Modifying the reactions cell and plating conditions further improved the film quality.

This paper presents the practical pressure control of hydraulic oil-pump system using SR drive for industrial application. In order to get a high performance of pressure dynamics in actual application, a data based PID control scheme is proposed in this paper. The proposed control scheme is verified by the experimental test.

CO2 laser had enabled accurate and effective cutting. But its application has been limited to thin and small parts. Development of a high power oscillator and oscillator built-in cutting machine have realized cutting of thick and large steel parts. This machine brings also possibility of fully automated cutting systems to practical steel parts such as for construction machinery.

Force/torque sensors are now providing widespread practical solutions to manufacturing problems, particularly in the area of automated assembly. The current state of the industry is discussed, including the evolution of transducer and controller design, and the trend of robot manufacturers to integrate force/torque sensors into their robot systems thereby greatly improving cycle time and simplifying the application development task for the end-user. Current and future application areas are discussed as well as the benefits of force/torque sensing.

RI-Biomics is the new radiation fusion technology of which, such as the characteristics of radioisotope, is applied to the biomics. In order to sharing and overall analysis of data between the institutions through total management of information in the field of RI-Biomics, RI-Biomics Information portal 'RIBio-Info' was constructed by KARA (Korean Association for Radiation Application) in February 2015. For systematic operation of this 'RIBio-Info' system, it is required to develop system of collection-analysis-application of information. So, in this paper, we summarized development of document forms at each processes of collection-analysis-application of information and systematization of collection methods of information, establishment of characteristically analysis methods of reports such as issue paper, policy report, global market report and watch report. Therefore, these are expected to improving the practical applicability in this field through the vitalization of technology development of users by achieving the circular structure of collectionanalysis-application of information.

Sulfonylurea(SU)계 제초제에 대한 저항성 물옥잠이 최근 한국에서 발생되고 있는데, 저항성 물옥잠 을 시기적절하게 효과적으로 방제하기 위해서는 신속 정확하고 실용적인 조기진단법 개발이 매우 중요하다. 지금까지 제초제 저항성 검증은 종자를 파종하여 어린식물에 제초제를 살포하는 방법을 사용하였으나 이러한 방법은 많은 시간이 소요될 뿐만 아니라 비실용적이다. 그러나 본 연구는 지표로부터 $1\sim2cm$에서 식물체를 절단한 다음 제초제를 처리하여 식물체의 생존율과 재생된 초장에 의하여 저항성을 검증하는 신속 정확한 새로운 방법이다. 이 새로운 조기진단법에 의하여 SU계 제초제 저항성 물옥잠은 적어도 7일 이내 저항성 검증이 가능하였다. 제초제 저항성이 진단되면 잡초를 효과적으로 방제하기 위해서는 식물 생육 단계에 맞는 제초제를 선발하는 것이 매우 중요하다. SU계 혼합 제초제 처리 후 생존한 저항성 물옥잠은 butachlor+pyrazolate 입제나 bentazone 액제와 2,4-D 액제를 혼용하여 처리하는 것이 효과적이었다.
