Application of Matrix Thinking Method to Introduction Program in Engineering Education
Y. Satoh,K. Takahashi,Y. Takahata,김윤해,S. Kubota 한국공학교육학회 2010 공학교육연구 Vol.13 No.2
From a lot of survey, it is obvious that most students in universities lose their desire for learning just after enteringtheir universities. In order to solve this problem, we developed a novel educational tool for the students, named “Thethinking method based on matrix diagram”. If they try hard with the help of this tool, they will be able to learn how todesign and manage their splendid university lives in addition to get the basic knowledge and to improvetheir basic abilities.It is also found that they can earn the shared knowledge mutually after learning a common method, which supports to makethem to improve their communication abilities drastically.
Association of a polymorphism of BTN2A1 with myocardial infarction in East Asian populations
Yamada, Y.,Nishida, T.,Ichihara, S.,Sawabe, M.,Fuku, N.,Nishigaki, Y.,Aoyagi, Y.,Tanaka, M.,Fujiwara, Y.,Yoshida, H.,Shinkai, S.,Satoh, K.,Kato, K.,Fujimaki, T.,Yokoi, K.,Oguri, M.,Yoshida, T.,Watanab Elsevier Scientific Publ. Co 2011 Atherosclerosis Vol.215 No.1
Objective: We have performed a genome-wide association study (GWAS) to identify genetic variants that confer susceptibility to myocardial infarction (MI) in Japanese and Korean populations. Methods: A total of 17,447 Japanese or Korean individuals from four independent subject panels was examined. Japanese subject panels A, B, and C comprised 134 individuals with MI and 137 controls, 1431 individuals with MI and 3161 controls, and 643 individuals with MI and 1347 controls, respectively, whereas the Korean population comprised 1880 individuals with MI and 8714 controls. A GWAS for MI was performed in Japanese subject panel A with the use of the Affymetrix GeneChip Human Mapping 500K Array Set. Results: Seventy single nucleotide polymorphisms (SNPs) significantly (P<1.0x10<SUP>-7</SUP>) associated with MI by the GWAS were examined further in Japanese subject panel B, revealing two SNPs (rs6929846 of BTN2A1, rs2569512 of ILF3) to be significantly (P<0.0007) associated with MI. The rs6929846 SNP of BTN2A1, but not rs2569512 of ILF3, was also significantly associated with MI in Japanese subject panel C. However, the association of neither rs6929846 nor rs2569512 with MI was replicated in the Korean population. Conclusion: BTN2A1 may be a susceptibility gene for MI in Japanese individuals.
Neutron-Production Double-Differential Cross Sections from Heavy-Ion Interactions
D. Satoh,D. Moriguchi,T. Kajimoto,Y. Koba,Y. Nakamura,N. Shigyo,M. Ueyama,Y. Uozumi,M. Yoshioka,N. Matsufuji,M. Takada,T. Sanami 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.23
The existing data of neutron-production double-differential cross sections on C, Cu, and Pb targets bombarded with heavy-ions from He to Xe at 230 - 600 MeV/nucleon were revised by using a new set on neutron-detection efficiency values of an NE213-type liquid organic scintillator calculated with SCINFUL-QMD. The revised data were compared with the experimental data obtained by our new measurements, and the predictions of the Monte-Carlo particle transport codes, PHITS, FLUKA, MCNPX, and Geant4. While the revised and new experimental data showed good agreement, the Monte-Carlo codes failed to reproduce the high-energy peaks in the forward angular region.
Measurement of Neutron-Production Cross Sections for 290 MeV/u Carbon Ion Incidence
D. Moriguchi,Y. Nakamura,T. Kajimoto,Y. Koba,M. Ueyama,M. Yoshioka,N. Shigyo,Y. Uozumi,D. Satoh,T. Sanami,M. Takada,N. Matsufuji 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.23
Neutron-production double-differential cross sections for 290 MeV/u carbon-ion incidence on carbon target were measured with NE213 liquid organic scintillators by time-of-flight technique. NE213 liquid organic scintillators 12.7 cm in diameter and 12.7 cm thick were placed in the directions of 15˚, 30˚, 45˚, 60˚, 75˚, and 90˚. The typical flight path length was 4.0 m. In order to reduce neutrons from the beam dump, an iron and a concrete shield was placed between the detectors and the beam dump. For measurement of background, a shadow bar was set between the target and each detector. Neutron detection efficiencies were obtained by calculations with a Monte Carlo simulation code SCINFUL-QMD. The cross sections were obtained for neutron energy above 2.8 MeV. The experimental results were compared with the calculation data of the PHITS code.

Well-defined hydroxyl end-functionalized poly(n-hexyl isocyanate), PHIC-(OH)(2) and PHIC-(OH)(3), as rod-type macroinitiators were synthesized by the Cu-catalyzed azide-alkyne cycloaddition reactions of azido end-functionalized PHIC with ethynyl alcohol derivatives. The PHIC-(OH)(2) and PHIC-(OH) 3 were suitable macroinitiators for the ring-opening polymerization of L-LA and epsilon-CL leading to the synthesis of novel rod-coil type miktoarm star copolymers, PHIC-b-PLLA(2), PHIC-b-PLLA(3), PHIC-b-PCL2, and PHIC-b-PCL3, with controlled molecular weights, narrow polydispersities, and controlled arm numbers. Additionally, the thermal and solution properties of the obtained miktoarm star copolymers along with the corresponding block copolymers, PHIC-b-PLLA and PHIC-b-PCL, were characterized by TGA, DSC, and DLS analyses.
