Abstract: Provided are a video on demand (VOD) transmission/reception method and system using a divided transport stream (TS). The VOD transmission method includes setting a division coefficient for dividing a TS; dividing the TS into a unicast segment and multicast segments according to the division coefficient; and transmitting the unicast segment by using a unicast method and transmitting the multicast segments by using a multicast method.

Abstract: A film formation process is performed to form a silicon nitride film on a target substrate within a process field configured to be selectively supplied with a first process gas containing a silane family gas and a second process gas containing a nitriding gas. The method is preset to compose the film formation process of a main stage with an auxiliary stage set at one or both of beginning and ending of the film formation process. The main stage includes an excitation period of supplying the second process gas to the process field while exciting the second process gas by an exciting mechanism. The auxiliary stage includes no excitation period of supplying the second process gas to the process field while exciting the second process gas by the exciting mechanism.

Abstract: There is provided a band gap reference voltage generation circuit capable of reducing wake up time during transition from an idle mode to a normal mode and further capable of removing the RF noise of an output voltage.

Abstract: A phytoestrogen composition comprising an extract of Chinese licorice root (Glycyrrhiza uralensis Fisch), liquiritin or isoliquiritin isolated therefrom, which show estrogen activity and inhibitory effect on proliferation of cancer cells, as an effective ingredient. The Chinese licorice root extract, as well as liquiritin or isoliquiritin isolated therefrom, show estrogenicity but not androgenicity, suppress activity of the endocrine disruptor bisphenol-A and inhibit proliferation of cancer cells, e.g., breast cancer cells. The composition is usefully employed as a phytoestrogen for hormone replacement therapy and/or prevention and treatment of breast cancer.
