On Einstein-Hilbert type action of superon-graviton model(SGM)
The fundamental action of superon-graviton model(SGM) of Einstein-Hilbert
type for space-time and matter is written down explicitly in terms of the
fields of the graviton and superons by using the affine connection formalism
and the spin connection formalism. Some characteristic structures including
some hidden symmetries of the gravitational coupling of superons are manifested
(in two dimensional space-time) with some details of the calculations. SGM
cosmology is discussed briefly.Comment: 20 pages, Latex, some more discussions and new references adde
New Einstein-Hilbert-type Action and Superon-Graviton Model(SGM) of Nature
A nonlinear supersymmetric(NLSUSY) Einstein-Hilbert(EH)-type new action for
unity of nature is obtained by performing the Einstein gravity analogue
geomtrical arguments in high symmetry spacetime inspired by NLSUSY. The new
action is unstable and breaks down spontaneously into E-H action with matter in
ordinary Riemann spacetime. All elementary particles except graviton are
composed of the fundamental fermion "superon" of Nambu-Goldstone(NG) fermion of
NLSUSY and regarded as the eigenstates of SO(10) super-Poincar\'e (SP) algebra,
called superon-graviton model(SGM) of nature. Some phenomenological
implications for the low energy particle physics and the cosmology are
discussed. The linearization of NLSUSY including N=1 SGM action is attempted
explicitly to obtain the linear SUSY local field theory, which is equivalent
and renormalizable.Comment: 37 pages, Latex, Based on a talk by K. Shima at International

Association between generation gap in interest, familiarity and application of information and communication technology
Given the introduction of information and communication technology and its rapid progress in every society, its use and application is different between various social institutions in that it demonstrates the difference between previous and present generation. Hence, the research was conducted in the school year 2012-2013 with the aim of applying information technology among female high school students and their mothers in Gorgan Province. The research method is a descriptive-analytical method; using a cluster sampling, of 34 female schools 8 schools were randomly chosen and 260 students were included in the study out of 1625 students. Using collected questionnaires and information obtained from independent t-test the results indicated that there was a significant difference between the mean of familiarity, interest and mothers' and their children's use of information technology. © Medwell Journals, 2016
