  • In accordance with introducing extra high voltage system, system power plants have to be operated in underexcited condition, which causes temperature rise at the stator end portion of turbine generator. This Paper deals with (1) various elements affecting temperature rise and (2) methods of pre-estimating temperature rise.

  • A decrease in the birthrate and aging are progressing in Japan and several countries. In that society, it is important that physically weak persons such as elderly persons are able to take care of themselves. We have been developing exoskeletal robots for human (especially for physically weak persons) motion support. In this study, the controller controls the angular position and impedance of the exoskeltal robot system using multiple fuzzy-neuro controllers based on biological signals that reflect the human subject's intention. Skin surface electromyogram (EMG) signals and the generated wrist force by the human subject during the elbow motion have been used as input information of the controller. Since the activation level of working muscles tends to vary in accordance with the flexion angle of elbow, multiple fuzzy-neuro controllers are applied in the proposed method. The multiple fuzzy-neuro controllers are moderately switched in accordance with the elbow flexion angle. Because of the adaptation ability of the fuzzy-neuro controllers, the exoskeletal robot is flexible enough to deal with biological signal such as EMG. The experimental results show the effectiveness of the proposed controller.

  • When the Balise(the device to transmit information between the on-board equipment and the wayside equipment) failure occurs, it may not be able to transmit data(Telegram) required for the train running. And in some cases, it may be able to cause an accident. Therefore, both the Balise failure affecting train safety running and the hazard in accordance with Balise failure require some activities to establish them. General failure mode & hazard analysis associated with the Balise are described in UNISIG SUBSET-036 spec & UNISIG SUBSET-088 spec. And, with reference to these specifications, safety activities are being performed. In recent domestic railway, the train control system applying ETCS(European Train Control System) Level 1, 2 is being serviced and is being planned, and as part of this system, the Balise is being applied. The design-method of the Balise device for each manufacturer are different, therefore the Balise failure mode & failure rate are different, either. But the functionalities & transmission-data format(Telegram) of the Balise in ETCS Level 1, 2 application for each manufacturer are identical. Accordingly, the hazard caused by function-fail can be identical, either. In order to establish these hazard, in this paper, we analyzed the detailed functions of the Balise. And we analyzed the Balise failure types & failure effects in accordance with the detailed functions.

  • This study attempted to identify differences in Korean food consumption behaviors between groups of Japanese consumers segmented in accordance to their food-related lifestyles. This study was performed to provide Korean food service companies basic information to implement a strategy for the globalization of Korean food. As a result of the empirical analysis, the food-related lifestyles of Japanese consumers were deduced to the following four factors: "health and safetyoriented lifestyle", "palate and safety-oriented lifestyle", "economic efficiency-oriented lifestyle", and "simplicity-oriented lifestyle". Further, as a result of the cluster analysis, food-related lifestyles were classified into the following three groups: "a group highly interested in food-related life", "an economic efficiency-oriented group", and "a simplicity-oriented group". Second, there were significant differences in demographic characteristics and the characteristics of Korean food consumption behaviors between the groups. Third, also in a comparison of satisfaction with and loyalty to Korean restaurants with crucial attributes during the selection of Korean food, there were significant differences between the groups. Therefore, it is necessary to develop various Korean food products that will cater to Japanese consumers in accordance with each segmented group.
