The floor structure of a railway car in one of the main structure of the railway car should support the many things such as chairs, passengers and electronic units which are hung to the structure. One of main functions of the floor structure of the railway car besides the supporting function is fire-resistance performance for fire safety of the railway car. In this study a new type of a floor structure of a railway car adopted an aluminum porous sandwich panel and urethane foam are introduced for weight reduction and easiness of installation, respectively. The fire-resistance performance of the three specimens of the floor structure of a railway car are tested. Two of them are assembled the sandwich aluminum porous panel and the other is assembled a plywood as a supporting floor for the reference test. Urethane foam and glass fiber for of insulation materials are considered.

Coronary artery disease is the most important cause of mortality in patients with systemic lupus erythematous (SLE). After stenting for coronary artery disease in SLE patients similar to non-SLE patients, the risk of stent thrombosis is always present. Although there are reports of stent thrombosis in SLE patients, very late recurrent stent thrombosis is rare. We experienced a case of very late recurrent stent thrombosis (4 times) in a patient with SLE.

Thermal behaviors of combined weapon systems have been analyzed in this study by developed computational programs. Also, temperature distributions of the materials of the system have been measured for the experimental conditions. Field tests in the large environmental tester have been prepared by the calculated thermal flow characteristics and the measured temperature distributions of the materials for the weapon systems. The boundary conditions of the analysis are composed of inlet and outlet conditions of the environmental tester and the limit of low temperature of −32°C. The soaking time of the system including a fuel tank and a battery in the environmental tester has been obtained by developed programs in this study to carry out the experiment in the predicted conditions.
