Effect of vertical layout and horizontal layout of three analog meters on reading errors was experimentally compared. Virtual meter panels with straight layout of three meters was instrumented by Visual Basic 2008 Express Edition. When eyes could move at right angles to the layout angle of meters,the magnitude of reading error hardly depends on the layout angle of meters. But if the virtual meter panel is designed carefully such as to avoid the motion of eyes at right angles to the layout angle of meters, the magnitude of reading error at vertical layout is smaller than that at horizontal layout.

In this paper, we proposed the real-time control system on non-real-time OS using the micro computer with USB interface. Generally, it was expensive and difficult to construct the real-time control system. However, we achieved proposed system inexpertly by using the micro computer as a scheduler.The characteristic are no special interface for the control software like MATLAB and the real-time control performance on the non-real-time system. Moreover, we developed the 2-link robot arm to evaluate the performance of the proposed system. As a result, the proposed system operated in the low-speed area.

This paper describes the improvement of originally proposed solar-cell circuit model applicable to more various different size solar panels including for home solar power generation system. Optimization of resistor values and transistor model selection of the equivalent circuit enables application to larger solar-cells which generate higher voltage and higher current. This circuit model is useful for total circuit simulation of electric system whose power is supplied by solar cells. Especially, it is useful for MPPT (Maximum Power Point Tracking) design to extract maximum solar electric power. Using these equivalent circuits connected to step-up converter or SEPIC(Single Ended Primary Inductance Converter) type step-up/down converter, maximum power point operation of solar-cells can be designed by circuit simulation.

Teaching materials of measurement and control systemsfor students in junior high school and freshmen in college of technology were discussed using visual programming language named Scratch.The interface board which connects light sensor,potentiometer and push switch to a PC was developed by using a PIC18F2550 microcontroller with USB interface. A DC Motor was connected to the interface board via H bridge circuit as output device. Temperature control experiments were realized using a thermistor and a Peltier device instead of the light sensor and DC Motor, respectively. Temperature control on Peltier device with high accuracy was performed by the PC running Scratch programs. Developed materials may be useful for ndustrial arts in junior high school and introductory education in college of technology.

In this paper we describe implementation and evaluation of a playout program for Monte Carlo Go playing system. Monte Carlo Go requires a huge number of random play called playout in each move, so its speed is very important. Our techniques are delaying calculation of the exact number of dames until really needed and excluding safe territory from the move candidate points. The playout program can perform 25,970 playouts per second for 9×9 grid Go board and 6,774 playouts per second for 19×19 grid board.

Reflection on classroom teaching practices and experiences has been commonly and correctly regarded as essential for in-service English teachers' development. In order to reinvent themselves day after day, teachers need to reflect upon professional experiences within a specific context and relate them to the broader issues of teaching and learning. The only problem, however, is that effective tools and strategies for reflection have not been developed yet. In this paper, 'Self-access Checklist Ver.1.1 for In-service English Teachers' Reflection of Classroom Teaching Practice' developed by the author, its application methods and usability are to be discussed for self-access and collaborative lesson studies by in-service English teachers wishing to manage their own professional development.

Light sources for plant leaf excitation were made by using ultraviolet LEDs (375nm) and near-ultraviolet LEDs (400nm) with optical filters which absorb visible light.The fluorescence spectra were able to be measured by the LEDs excitation of more than 30Wm-2 as well as the laser excitation. A Multipoint Measurement Device (MMD) of plant fluorescence was made by combining a macro lens, an imaging spectrometer, a chilled CCD camera and so on. By the ultraviolet LEDs excitation, the fluorescence spectra of a spider plant (Chlorophytum comosum) leaf, a pothos (Epipremnum aureum) leaf, and the partially UV-B treated peanut (Arachis hypogaea L.) leaf were measured with the MMD system. The distribution of fluorescence ratios (F430/F530, F685/F530, F740/F685) on each leaf were observed in detail. The accuracy of the plant growth monitoring can be improved by this technique.

The new approaches in chemical experiments for chemical education in KNCT are reported. Recent approaches are application of microscale chemistry, preparation of "chemistry box", introduction of molecular models, and utilization of computer soft wares. The improvements are evaluated using questionnaires to students. This report and the discussions would be useful for future education in chemistry.
