Fabrication and characterization of a dye-sensitized solar cell containing porphyrin derivative
Get PDFThis is a report on the fabrication and characterization of a dye-sensitized solar cell (DSSC) containing non-carboxylated porphyrin (5,10,15,20-tetrakis-(4-aminophenyl)porphyrin,TAPP)and various cyclodextrins(CDs).The photoelectric conversion of DSSC resulted from light harvesting of TAPP. The open-circuit voltage (Voc) was 0.41 V for DSSC without CD. On the other hand, it increased to 0.47 V, 0.47 V, 0.45 V, 0.49 V containing α-CD, β-CD, CM-β-CD, and γ-CD respectively. The photovoltaic performance increased by electron recombination, which is induced by the formation of an incorporation complex of TAPP with CDs(TAPP/CDs).As a result, we concluded that the TAPP/CDs act as photosensitizer for a DSSC.These results indicate that our techniques can be used for future research on the fabrication of porphyrin-dye DSSC.departmental bulletin pape
The Student Guidance Office 2017 Annual Report
Get PDFThis article reports statistics and some activities in the student guidance office as 2017annual report. From the results, there has been an increase in the number of counseling since 2012. Further, in this year, 65 out of 104 students who received counseling came to the student guidance office for the first time. Approximately, one-third of the students came there voluntarily and a quarter of them came there through screening interview after they took UPI test. These results implied that the student guidance office has come to be perceived as a place where many students feel free to counsel. In the future, it is necessary to consider group work aimed at improving students' communication skills and self-understanding according to the needs of students using the student guidance office.departmental bulletin pape
Optimization of Pulmonary Elastance Polynomial Model Using Immune System
Get PDFWhen patient give artificial respiration to the body, the suitable setting of ventilation condition is needed for every patient. However, the parameter setting of the respirator is decided by experience and the perception of the doctor now. Therefore, we proposed a setting method using a static P-V curve. In order to realize a proposed method, it is necessary to improve the estimation accuracy of the static P-V curve. This study proposes optimisation technique of pulmonary elastance polynomial model construction using Immune System from real patient data. First, we explain the embedding method of Immune System to this study. Then, we show the effectiveness of the algorithm by using a optimisation result.departmental bulletin pape
Developing a Simple Method for Estimating the Cross-sectional Area of Abdominal Muscles Using Ultrasound Imaging
Get PDFIn this study, we aimed to develop a simple and non-invasive method to estimate the cross-sectional area of abdominal muscles using images from an ultrasound imaging diagnostic device. The target sites were the rectus abdominis muscle, abdominal external oblique muscle, and abdominal internal oblique muscle. The subcutaneous tissues were imaged with the B mode and stored. Imaging sites were from the umbilical region to a point that intersected the line drawn straight down from the axilla (the edge of the external and internal oblique muscles). We obtained images by shifting the width of the probe. Using the analytical software developed in this study, we input the obtained images, adjusted the position for the images to line up, and identified the area of each muscle group and calculated the cross-sectional area. We hope that the analytical software developed in this study will be used as a simple and non-invasive method to estimate the cross-sectional area of muscles, regardless of the types of ultrasound imaging diagnostic devices.departmental bulletin pape
Evaluations of Psychology Education to Enhance Critical Thinking Ability and Meta-Cognition Skills for University students:Through Pre- and Post -Test, and One- and Two- year Follow-up Studies
Get PDFThis study examined evaluations of psychology education to enhance critical thinking ability and meta-cognition skills for university students. University students had taken lesson in critical thinking and meta-cognition and did worksheets after receiving lectures about them in “Introduction to Psychology" class. Although the results of pre- and post- tests demonstrated significantly improved higher levels of critical thinking ability, no significant results between the implementation and control groups have been demonstrated in the follow-up studies had about one year and two years after the class had finished. On meta-cognition skills, no significant results have been demonstrated at pre- and post-test and follow-up studies. The results showed that this study revealed the beneficial effect of implementing the program for developing critical thinking skills in the class although it was possible to maintain the effect. Moreover it suggested that it is necessary to design not only longitudinal study and qualitative research to examine factors for enhancing and maintaining students' critical thinking and meta-cognition skills.departmental bulletin pape
Comparison of the Site Scale in the Castle Town A Study on the Tradesmen's Premises in the Fukui Castle Town, part1
Get PDFThis paper compares of the site scale of the tradesmen's premises in the Fukui Castle Town. The towns with large area were Kyomachi along the HokurikuKaido, Gofukumachi, Honmachi and Chojamachi on the east side. Town such Honmachi, Gofukumachi, Chojamachi is central towns, and many houses have an area of more than 40 Tsubo. Town such as Komemachi, Daikukumachi and Uomachi were back streets, among them the site was narrow compared to the central towns. The central towns of 8 towns are over 35.3 Tsubo which was the average value of the number of squares. On the other hand, the average of site scales smaller than 20 towns such as Seigenjicho and Komemachi. The area of the west side of the Hokurikukaido was less than the average value, among them Hachimancho was the smallest.departmental bulletin pape
Studies of Servo Control System and Building Estimate System for Autonomous Proximity Operations of the Weeding Robot “TAMBA"
Get PDFIncreased public interest in food safety and clean agriculture (e.g., ecological agriculture, organic culture and agrochemical-free cultivation) is driving a production system change from dependence on and use of agrochemicals toward their elimination. However, this raises a huge time- and labor-consuming problem with weeds. The weeding robot “TAMBA" decreases weeds in paddy fields without resorting to herbicides. "TAMBA" autonomously travels while avoiding rice plant rootstocks. Final goal is to runs on schedule, return to the docking station and recharge like “ROOMBA". In this time, we studied servo control system for 4 servo-motors and 4 brushless-DC-motors. Additionally, we built up estimate system. We can use this estimate system for studying image processing algorithm on the Raspberry Pi with USB cameras.departmental bulletin pape
A Factorial Investigation into the English Language Learning Anxiety of First-Year University Students in Japan
Get PDFAnxiety in the foreign language classroom is an individual difference among learners that can have a direct impact on the success of learning a foreign language. Through factor analysis this study aimed to classify different types of anxiety present in the English language learning classroom at a rural private Japanese university. Using the Foreign Language Classroom Anxiety Scale (FLCAS), 146English language learners were surveyed. A five-factor solution was found with the factors interpreted as: anxiety related to oral production, attitudes regarding course enjoyment, degree of comfort when communicating with L1speakersof English, comparison anxiety, and the fear of being unsuccessful or falling behind. It was found that this particular group of learners experience anxiety when forced to produce unprepared language output, when communicating with native speakers, and when there is potential to be compared to classmates.departmental bulletin pape

Quality Monitoring of Paddy Rice Using Satellite Image Data
Get PDFWe have been researching to support production of rice with good taste by using satellite image data. Specifically, we aim to extract protein content of rice using satellite image data before harvesting. When comparing measured values such as growth condition and protein content of rice with satellite image data, it is necessary to consider the difference of phenology by varieties of rice. So, as a first step towards monitoring rice quality, a method for determining varieties of rice using Landsat-8 OLI data was proposed. Next, in order to estimate the protein content of rice using a vegetation index (NDVI) obtained from the satellite image, it was analyzed which satellite image (observed at which season) should be used. Furthermore, as a result of investigating the new vegetation index instead of NDVI, the estimation accuracy of rice protein content using the new index was greatly improved.departmental bulletin pape
