A tool support for verifying consistency between UML diagrams by SMV
Shinji HARADA,Tomoyuki YOKOGAWA,Hisashi MIYAZAKI,Yoichiro SATO,Michiyoshi HAYASE 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7
We develop a tool to support verification of consistency between designs described by UML diagrams. This tool translates an XML data exported from a UML drawer into an input of SMV (called SMV program). This tool provides afront-end which parses an XML data and generates an intermediate data. This tool also provides a back-end which generates an SMV programfrom the intermediate data. We show the availability of our tool by applying it to an example.
The Effect of Magnetic Nozzle for Disk Magnetohydrodynamics Accelerator
Takeshita, Shinji,Harada, Nobuhiro The Korean Institute of Electrical Engineers 2013 The Journal of International Council on Electrical Vol.3 No.1
The purpose of this article is to investigate the effect of magnetic nozzle for disk Magnetohydrodynamics (MHD) accelerator using by Q1D (quasi-1-dimentional) numerical simulation. As results, as constant applied magnetic field of 2T is supplied to the MHD channel and 3, 6, 8 and 10T are supplied to the nozzle, acceleration performance for these cases could not observe the significant difference. However as applied magnetic field of 3, 6, 8 and 10T are supplied to downstream side of the MHD channel and the nozzle, gas velocity for case of 6T was accelerated to 3170m/s and 10T was accelerated to 3040m/s. Because of excessive applied magnetic field induced compression due to joule heating and friction loss.

Background: Although the utility of flaps for the treatment of sternal wound infections following median sternotomy has been reported for 30 years, there have been few reports on the risk factors for complications after reconstruction. The objective of this investigation was to identify factors related to complications after the reconstruction of sternal wound infections. Methods: A retrospective analysis of 74 patients with reconstructive surgery after sternal wound infection over a 5-year period was performed. Clinical data including age, sex, body mass index (BMI), comorbidities, bacterial culture, previous cardiac surgery, wound depth, mortality rate, type of reconstructive procedure, and complication rate were collected. Results: The patients’ BMI ranged from 15.2 to 33.6 kg/m2 (mean, 23.1±3.74 kg/m2). Wound closure complications after reconstructive surgery were observed in 36.5% of the cases. The mortality rate was 2.7%. Diabetes mellitus significantly affected the rate of wound closure complications (P=0.041). A significant difference in the number of complications was seen between Staphylococcus aureus (S. aureus) and coagulase-negative Staphylococci (P=0.011). There was a correlation between harvesting of the internal thoracic artery and postoperative complications (P=0.048). The complication rates of the pectoralis major flap, rectus abdominis flap, omentum flap, a combination of pectoralis major flap and rectus abdominis flap, and direct closure were 23.3%, 33.3%, 100%, 37.5%, and 35.7%, respectively. Conclusions: Diabetes mellitus, S. aureus, harvesting of the internal thoracic artery, and omentum flap were significant factors for complications after reconstruction. The omentum flap volume may be related to the complications associated with the omentum flap transfer in the present study.
Quantitative Analysis of ″Polymer-Balls″ in Aqueous Solutions by Small-Angle Neutron Scattering
Shibayama, Mitsuhiro,Okabe, Satoshi,Nagao, Michihiro,Sugihara, Shinji,Aoshima, Sadahito,Harada, Tamotsu,Matsuoka, Hideki The Polymer Society of Korea 2002 Macromolecular Research Vol.10 No.6
The quantitative analysis of polymer micelles consisting of amphiphilic block copolymers was carried out by small-angle neutron scattering (SANS). The block copolymers, made of poly(2-ethoxyethyl vinyl ether-b-2-hydroxyethyl vinyl ether)(poly(EOVE-b-HOVE)), exhibited a sharp morphological transition from a homogeneous solution to a micelle structure with increasing temperature. This transition is accompanied by a formation of spherical domains of poly(EOVE) with a radius around 200 $\AA$. The variations of the size and its distribution of the domains were investigated as a function of polymer concentration and temperature. The validity of SANS analysis, including the wavelength- and incident-beam-smearing effects of the SANS instrument, was examined with a pre-calibrated polystyrene latex.

Clinical data including age, sex, body mass index (BMI), comorbidities, bacterial culture, previous cardiac surgery, wound depth, mortality rate, type of reconstructive procedure, and complication rate were collected.
