This study was to compare the tensile bond strength and flexibility of four different soft liners(Coe-Soft, Soft Relining, Soft-Liner, Dura Base Soft) before & after thermocycling. Each soft liner was bonded to denture base resin block, and measured the tensile bond strength and modulus of elasticity using Universal testing machine. The mean value of tensile bond strength and modulus of elasticity for each experimental groups were statistically processed by SPSS(Statistical Package of Social Science). The obtained results were as follows : 1. Dura Base Soft had the highest tensile bond strength and Coe-Soft had the lowest tensile bond strength. 2. Coe-Soft had the lowest modulus of elasticity, and Dura Base Soft had the highest modulus of elasticity. 3. Thermocycling had no effects on the tensile bond strength and modulus of elasticity of all the soft liners. 4. The failure modes of Coe-Soft, Soft Relining, Soft Liner were mainly cohesive failure, and that of Dura Base Soft were mainly adhesive failure.

Recently, Most of diverse noise of vehicles has decreased competitively according to development of the automotive manufacturing technology. Especially, Passenger car manufacturers has been conducting buzz, squeak and rattle(BSR) noise test as a method of the noise evaluation tests to reduce an unpleasant sound from interior parts on the driving the car. The purpose of this paper is to confirm the change of the noise generated in the product after the reliability evaluation. Here by the BSR test procedure used the test regulation of G company.

In a state where ancient buildings was left a lot in the case of Korea, many parts do not remain the documentation, and there is a Kiwarisho lot in Japan, however, the present methods and tree split does not exist in the Korea. However, it is impossible to make a perfect building without splitting exact member when making a building. Thus will not be revealed simply by presumption that there is a similar way to wood comparatively far in Korea. Without a comparison of building dimensions and Korea calculation dimensions Kiwarisho In the first study about the proportionality of Korea, I do not know until now, other studies of the following documents which house a high approximation ratio and member size of Korea consider reason to have is impossible. View compared with respect to the axis of the building in the early stages of research first. In the case of Japan and Korea to form a tree frames in basic form that form the building, the shaft portion is easy to understand and easy compared in common is at most the shaft portion.

모듈은 동적으로 커널에 적재 가능한 오브젝트 파일로써 적재된 이후에는 커널의 권한으로 모든 자원에 대해 완벽한 접근 권한을 가진다. 따라서 잘못 작성된 모듈이나 혹은 정상적으로 작성된 모듈이라 할지라도 운영체제의 상황에 따라 비정상 수행되는 경우 시스템 전체의 안정성과 신뢰성에 치명적인 영향을 끼친다. 따라서 본 논문에서는 모듈이 발생시킬 수 있는 다양한 자원관련 문제를 해결하기 위해 커널 자원 보호자를 설계하였다. 커널 자원 보호자는 메모리, 주 번호, 워크 큐 등 운영체제가 관리하는 다양한 자원에 대한 보호를 제공한다. 제안된 기법은 리눅스 2.6.18에 실제 구현되었으며, 실험을 통해 본 논문에서 제안한 커널 자원 관리가 커널 자원을 효율적으로 보호하고 있음을 보였다. Module is an object file that can be loaded into operating system dynamically and has complete privileged access to all resources in kernel. Therefore trivial misuses in a module may cause critical system halts or deadlock situations. In this paper, we propose Kernel Resource Protector(KRP) scheme to reduce the various problems caused by module. KRP provides protections of a variety of kernel resources such as memory, major number and work queue resource. We implement the scheme onto linux kernel 2.6.18, and experimental results show that our scheme can protect kernel resources effectively.
