Escherichia coli O157：H7, Staphylococcus aureus and Salmonella enteritidis are food borne pathogens involved in food poisoning in numerous countries. This study aimed to obtain knowledges on the survival of Esc coli O157：H7, Sta aureus and Sal. enteritidis in the yoghurt added with water extract of Omija(Schizandra chinensis). The growth inhibition of Schizandra chinensis extract on the food borne pathogens were measured by total microbial count and effect of growth inhibition was correspondent to the concentration of Schizandra chinensis extract. The highest growth inhibition effect of Schizandra chinensis extract was shown on the Sta aureus followed by Sal. enteritidis and Esc. coli O157：H7. The number of surviving Esc. coli O157：H7 cell(3.55${\times}$10$\^$5/ CFU/mL) was decreased to 1.00${\times}$10$^1$∼3.00${\times}$10$^1$ CFU/mL after 24 hours incubation by the addition of 0.4∼l.0％ of Schizandra chinensis extract in the yoghurt. And also the viable cell counts of surviving Sta. aureus cells (initial inoculum 1.24${\times}$10$\^$5/ CFU/mL) were decreased gradually to 4.00${\times}$10$^2$∼8.50${\times}$10$^2$ CFU/mL after 48 hours of incubation, but the viable cells of Sal. enteritidis were not detected after 24 hours of incubation. Growth of the food borne pathogens was strongly inhibited by the addition and incubation of Schizandra chinensis extract for 48 hours in the yoghurt.

In this paper, we characterize the support for the Dunkl transform on the generalized Lebesgue spaces via the Dunkl resolvent function. The behavior of the sequence of $L^p_k$-norms of iterated Dunkl potentials is studied depending on the support of their Dunkl transform. We systematically develop real Paley-Wiener theory for the Dunkl transform on ${\mathbb{R}}^d$ for distributions, in an elementary treatment based on the inversion theorem. Next, we improve the Roe's theorem associated to the Dunkl operators.

Concentrations of Fe, Mn, Zn, Cu, Pb and Cd in two seaweed species (Sargassum miyabei and S. pallidum) from different areas in Amursky Bay near Vladivostok were determined. An assessment of heavy metal pollution in this bay was made and the results were compared with those from some localities in the world ocean.

In this study, we analyze the dependence structure of KOSPI and NYSE indices based on a two-step estimation procedure. In the rst step, we adopt ARMA-GARCH models with Gaussian mixture innovations for marginal processes. In the second step, time-varying copula parameters are estimated. By using these, we measure the dependence between the two returns with Kendall's tau and Spearman's rho. The two dependence measures for various copulas are illustrated.

We study the geometry of half lightlike sbmanifolds M of a semi-Riemannian space form $\tilde{M}(c)$ admitting a semi-symmetric metric connection subject to the conditions: (1) The screen distribution S(TM) is totally umbilical (geodesic) and (2) the co-screen distribution $S(TM^{\bot})$ of M is a conformal Killing one.

The aim of this paper is to obtain twenty five Eulerian type single integrals in the form of a general single integral involving $Kamp\acute{e}$ de $F\acute{e}riet$ function. The results are derived with the help of the generalized classical Watson's theorem obtained earlier by Lavoie, Grondin and Rathie. A few interesting special cases of our main result are also given.
