    High frequency response of load which is connected to transmission line is complicated, so it's difficult to understand the response by relatively short time learning. As one of the solution of such problem, use of microwave circuit simulator is introduced. The class using the simulator is designed to deepen the understanding about behavior of a microwave circuit. This report describes contents and results of the teaching.

    This paper describes a basic research results on the engineering visibility evaluation of the horizontal scroll display character in the LCD screen.It is studied subjective visibility of Japanese text that flows through the LCD screen in a single line from the right to the left. Text information of the random arrangement “katakana” is used. The scroll speed, number of characters and the character size are investigated the effect on visibility. Certain of the character size and the number of characters that visibility is improved exist for the LCD screen size. To obtain a scroll speed suitable for the number of characters and character size, it is possible to improve the visibility. This study is considered to lead to obtain the guidelines for the future, improve the visibility of the dynamic character information.

    The purpose of this research is to develop the catchment lid of the precast concrete with the durability and the cost performance. At first, material characteristics of the concrete with which various short fiber was mixed were checked. An impact test of the catchment lid made with short fiber reinforced concrete was performed. It was showed that the concrete reinforced with short fiber increases in the strength to the impact. An experimental result of various short fiber reinforced concretes with the same aspect ratio was compared. The flexural toughness of the concrete mixed with polyvinyl alcohol fiber (PVA-fiber) was increased than others. Furthermore, a bending test of the catchment lid manufactured by PVA-fiber reinforced concrete was performed. It was indicated that this product is excellent in the building performance, the durability and the cost performance as a result of the experiment.

    A purpose of this paper is to clarify the architectural characteristics of Shimmuta Kato-jinja Shrine, Shima Amida-do and Shima Kannon-do in Yatsushiro-shi. Shinmuta Kato-jinja Shrine was founded in 1866, and the main shrine was built in 1886. After Sankaku-ji Temple was abolished, Shima Amida-do and Shima Kannon-do were founded. It is thought that the Amida-do was built in 1842. The main shrine of Shinmuta Kato-jinja Shrine has family crests of Kato Kiyomasa. The front shrine is architecture had module by span of Rokunima. The Amida-do and the Kannon-do are architectures have a module by scale of Kyoma-Tatami.

    A purpose of this paper is to clarify the architectural characteristics of Io-ji Temple, the Matsui family’s place of prayer, in Yatsushiro City. The temple keeps many cultural properties, and the Main hall itself is a cultural properties designated by Yatsushiro City. But there was not an investigation about the architecture until now. We made the survey drawings, arranged the historic change and compared that with the other prayer’s places in Yatsushiro City. The Main hall was built in 1665. It is the biggest and the most prestigious architecture for the place of prayer in Yatsushiro City. Particularly, the gate for the Matsui family exists.

    For evacuation drills, multiple events should also be considered as well as an evacuation route out of the school building, because many complex evacuation situations can possibly happen. This study aims to examine the consequences for remediation of school evacuation drill by predicting some different situations of evacuation, which have become more complicated than situations commonly used in evacuation drill. In this study, multi-agent pedestrian simulation application –SimTread- is applied to predict multiple different evacuation conditions. As a result of the study, the conclusions are as follows: 1) Under all evacuation situations, overcrowding tends to arise since many evacuees cross at connections between corridors and staircases, at downstairs narrower than adjacent corridors, and around the exit from the building. 2) Arrival time at the evacuation destination from each classroom increases due to complexity of evacuation situations. This tendency becomes clearer on the upper floors. 3) Even with students in the same class, their arrival time at the evacuation destination greatly differs depending on the classroom location. Particularly on the upper floors, the positional relationship between a classroom and downstairs affects significantly on the evacuation time.
