Landslide damage comprise most part of the damages from the earthquake and it only causes the damage to lives and structures directly but also cease the operation of social system by road or lifeline failure. For these reasons hazard assesment on the landslides has been recognized very important. And hazard maps have been used to visualize the hazard of the landslide. In this study as first step for application of hazard map to domestic cases hazard maps are made for the Ul-Joo Ul-san Korea, Where the Yan-san faults are located. For building hazard maps the degree of hazard are evaluated based on Newmark displacement and the resulting maps are constructed by GIS technique. In hazard assesment maximum ground acceleration obtained from attenuation equation of wave propagation and design earthquake acceleration suggested by Ministry of construction are used for acceleration term. Hazard maps are made by GIS programs Arc/Info and Arc/View based on the digital maps and data from lab tests and elastic wave surveys The maps show the possible landslide regions significantly and the displacements of slide are proportional to the slope angles.

The failure modes of pneumatic directional control valves include leakage, wear of the spool seal, and sticking of the spool. Among them, the main failure mode of the valve is leakage. The leakage is caused by the wear of the spool seal. However, due to the characteristics of the seal material, the leakage rate is fluctuated a lot rather than constantly increased over time. If life analysis is performed using the first time data of leakage failure, predicted life cycles can be different from the real life cycles. This paper predicts life cycles of the pilot pneumatic directional control valve based on the three point moving average which considers the average of the fluctuating leakage rate.

최근 새로운 평가 체제로 대두되고 있는 수행 평가에 대한 체계적인 선행 연구의 부족으로. 초등학교 교사들은 수행 평가 문제를 직접 연구, 개발해서 아동들에게 적용시켜야 하는 부담을 안고 있다. 본 논문에서는 현재 제주도내 초등학교에 근무하고 있는 교사들을 대상으로 지금교육 현장에서 실시되고 있는 수행 평가의 실태 및 수학 교과에서의 수행 평가 방법의 유형에 대한 선호도와 앞으로 개발되어야 할 수학 교과에서의 수행 평가 방법의 유형에 대한 선호도를 설문 조사하여, 각 학년에 투입 가능한 수행 평가 유형을 찾아보았다.

Recently, among those general contractors and construction material production companies in korea, this concept is lively obtained to reduce the floor impact sound. This attempt is continuously tried for developing the floor impact isolation material. However the assesment of the isolation performance is often ignored and even there seems no differences in comparison with the general the isolation performance of the floor impact. This is often occurred for their only respect with the material of the floor impact isolation performance. Therefore, this study analysed the expected problems for site application of currently applied the isolation material and its capacity which as the floor impact reducing material, and presented several major assesment items and checklist which should be inspected in advance of their development or site application.

The objective of the present study is to develop methodology for the assesment of combustion stability of liquid rocket injectors. To simulate actual combustion occurring inside of a thrust chamber, a full-scale injector has been employed in the study, which burns gaseous oxygen and mixture of methane and propane. The main idea of the experiment is that the mixing mechanism is considered as a dominant factor significantly affecting combustion instability in a full-scale thrust chamber. Single & multi split triplet injectors have been used with an open-end cylindrical combustion chamber. The characteristics revealed by excited dynamic pressures in gaseous combustion show degrees of relative acoustic damping depending on operating conditions. Upon test results, the direct comparison between various types of injectors can be realized for the selection of the best design among prospective injectors.
