Access Control with OpenID on the Web
Tadashi SHIROMA,Tetsuya HIGA,Tomokazu NAGATA,Yuji TANIGUCHI,Shiro TAMAKI,Morikazu NAKAMURA 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7
In recent years, Single Sign-On for the Web is demanded highly and OpenID was proposed. OpenID is usually used as a method for verifying the identifier of users. By contrast, we use OpenID as a method for proving the attributes or knowledge of users. In this article, we suggest an access control method using OpenID with the optional factors of the users on the Web.

This paper proposes a mathematical model of Caprine arthritis encephalitis (CAE), which is a disease causing significant economic damage to the goat farming industry, and reports the application of this model to the development of an information management system of animal quarantine to overcome this disease. The mathematical model of CAE was derived from the AIDs model in human case because epidemical characteristics of these diseases including infection pass are similar. This model can be expressed by simultaneous differential equations. Simulations using a new model were performed according Euler's and Runge-Kutta method using numerical analysis software. In each method, strong convergence was observed and the results were similar. The design of an information management system of animal quarantine was proposed as an application of the new model. System design was constructed on the assumption that in subtropical islands, the expected development of information infrastructure and utilization will become valuable in the future.
First Near-infrared Imaging Polarimetry of Young Stellar Objects in the Circinus Molecular Cloud

<P>We present the results of near-infrared (NIR) linear imaging polarimetry in the J, H, and K-s bands of the low-mass star cluster-forming region in the Circinus Molecular Cloud Complex. Using aperture polarimetry of point-like sources, positive detection of 314, 421, and 164 sources in the J, H, and Ks bands, respectively, was determined from among 749 sources whose photometric magnitudes were measured. For the source classification of the 133 point-like sources whose polarization could be measured in all 3 bands, a color-color diagram was used. While most of the NIR polarizations of point-like sources are well-aligned and can be explained by dichroic polarization produced by aligned interstellar dust grains in the cloud, 123 highly polarized sources have also been identified with some criteria. The projected direction on the sky of the magnetic field in the Cir-MMS region is indicated by the mean polarization position angles (70 degrees) of the point-like sources in the observed region, corresponding to approximately 1.6 x 1.6 pc(2). In addition, the magnetic field direction is compared with the outflow orientations associated with Infrared Astronomy Satellite sources, in which two sources were found to be aligned with each other and one source was not. We also show prominent polarization nebulosities over the Cir-MMS region for the first time. Our polarization data have revealed one clear infrared reflection nebula (IRN) and several candidate IRNe in the Cir-MMS field. In addition, the illuminating sources of the IRNe are identified with near-and mid-infrared sources.</P>

NEAR-IR POLARIMETRY AROUND 30 DORADUS: I. SEPARATION OF THE GALACTIC SOURCES
Kim, Jae-Yeong,Pak, Soo-Jong,Choi, Min-Ho,Kang, Won-Seok,Kandori, Ryo,Tamura, Motohide,Nagata, Tetsuya,Kwon, Jung-Mi,Kato, Daisuke,Jaffe, Daniel T. The Korean Astronomical Society 2011 Journal of The Korean Astronomical Society Vol.44 No.4
A $200'{\times}200'$ region around 30 Doradus in the Large Magellanic Cloud (LMC) is observed and analyzed in the near-infrared. We obtain polarimetry data in the J, H, and Ks bands using the SIRIUS polarimeter SIRPOL at the Infrared Survey Facility 1.4 m telescope. We measure the Stokes parameters of 2562 point-like sources to derive the degree of polarization and the polarization position angles. We discuss the statistics of the groups classified by color-magnitude diagram and proper motions of the sources, in order to separate the Galactic foreground sources from those present in the LMC. We notice that groups classified by the proper motion data show a tendency towards different polarimetric properties.
