GTFS-JP is the data format for public transportation released by the Ministry of Land, Infrastructure, Transport and Tourism in March 31, 2017. This format contains several additional attributes in GTFS (General Transit Feed Specification) data format. In addition, this format was formed as a standard for data creation in small bus operators and community buses where the creation of electronic data has been delayed. Since the format was released, GTFS-JP data has been created in several cities and small bus companies. However, the number of created GTFS-JP data is still small, and there are few reference cases on how to enter data and how to use maintained data. In this paper, I report the details of the development of public transport open data visualization system based GTFS-JP.
New materials for cat litter were prepared using calcined scallop shells, Wakkanai Biosiliceous Shale and pregelatinized starch. Obtained particles which have two-layers structure consisted of inner calcined shell core and outer pregelatinized starch layer show good performances of deodorization ability for ammonia, water extraction efficiency and cohesive as same as goods on the market. Additionally, the particles exhibit remarkable antimicrobial activity against E.coli that doesn't be observed for any manufactured ones.
The purpose of this study was to analyze the change in physical fitness and motor abilities of students in National Institute of Technology in Hokkaido through the practice of physical training in physical education classes. In this study, the subjects were 133 male students. Physical fitness was measured using “The New Physical Fitness Test” developed by Ministry of Education,Culture, Sports, Science and Technology. All values of the physical fitness test of subjects after the classes were significantly lower than national median. However, the values of grip strength and side steps increased significantly from the previous year. Further, the values of 20-m shuttle running were increased of the second grader in the group of increased exercise time. These results suggest that increasing the opportunity to take daily exercise is important for improvement in physical fitness of students in National Institute of Technology.
We have analyzed a galaxy-galaxy merger simulations performed by Matsui et al. 2012 and researched properties of star clusters (SCs) in a galaxy-galaxy merger remnant. We find that whereas most SCs have single stellar population, the rest have multiple stellar populations. These SCs with multiple stellar populations are produced by capturing dense gas and forming next generation stars when they pass dense gas regions. Since the captured gas is contaminated with metal ejected from TypeII supernovae, such SCs consists of stars with different metallicity.
