We investigated the structure of bacterial communities present in livestock manure-based composting processes and evaluated the bacterial succession during the composting processes. Compost samples were derived separately from swine manure, dairy manure and sewage sludge. The structure of the bacterial community was analyzed by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) using universal eubacterial primers. The genus Bacillus and related genera were mainly detected following the thermophilic composting phase of swine and dairy manure composts, and the members of the phylum Bacteroidetes were mainly detected in the cattle manure waste-based and sewage sludge compost. We recovered and sequenced limited number of the bands; however, the PCR-DGGE analysis showed that predominant diversities during the composting processes were markedly changed. Although PCR-DGGE analysis revealed the presence of different phyla in the early stages of composting, the members of the phylum Firmicutes and Bacteroidetes were observed to be one of the predominant phyla after the thermophilic phase.

The imaging spectroscopic observations of the Magellanic irregular galaxy NGC 4449 were made to show the detailed kinematic structure of the galaxy. Many filamentary structures and Several bubble-like structures are recognized in a 3D data cube of H$\alpha$ emission line. Velocity field shows the kpc-scale mosaic structure and counter- rotation of ionized gas.
The rate-determining step in the dark state recovery process in the photocycle of PYP
Sasaki, Jun,Kumauchi, Masato,Hamada, Norio,Tokunaga, Fumio Korean Society of Photoscience 2002 Journal of Photosciences Vol.9 No.2
The last step in the photocycle of photoactive yellow protein (PYP) is a spontaneous recovery of the dark state from the active state in which the p-coumaric acid chromophore is thermally isomerized, concomitantly with the deprotona- tion of the chtomophore and the refolding of the protein moicty. For the purpose of understanding the mechanism of the thermal back-isomerization, we have investigated the rate-determining step by analyzing mutant PYPs of Met100, which was previously shown to play a major role in facilitating the reaction (1). The mutation to Lys, Leu, Ala, or Glu decelerated the dark state recovery by 1 to 3 three orders of magnitude. By evaluating temperature-dependence and pH-dependence of the kinetics of the dark state recovery, it was found that the retardation by mutations resulted from elevation of the activation enthalpy ( H$\^$┿/) and that the pKa of the chromophore, which was affected by the mutation, is in a linier correlation with the amplitude of the rate constants. It was, therefore, deduced from the correlation that the free energy for crossing the activated state in the dark recovery process is proportional to the free energy for the deprotonation of the chromophore, identifying the rate-determining step as the deprotonation of the chromophore.

The Writing System of an Artificial Language : For Efficient Orthographic Processing
Sasaki, Miho Institute for University Language Sejong Instituti 2003 Journal of Universal Language Vol.4 No.1
The major purpose of this paper is to explore the role of orthography in language and to propose new approaches to the development of an artificial language in relation to reading and spelling. Recent second language acquisition research has shown evidence that orthography is one of the most important features for acquisition of reading skills. For many years, effects of orthographic regularity on efficiency of language processing have been underestimated. This paper looks at the relationship between orthography and phonology across languages and examines what is the optimal writing system. The writing system of Esperanto is also investigated in terms of orthographic regularity to uncover possibility of a simpler writing system.
日本語の文字種と書物の關係について -寫本の時代から版本の時代まで-
( Sasaki Takahiro ) 연세대학교 인문학연구원 2015 人文科學 Vol.103 No.-
Originally lacking an alphabet of its own, Japan made use of abbreviated or cursive Chinese characters to create katakana and hiragana, which stripped a character’s original semantic meaning to act as pure phonograms. Eventually Japanese came to be written using a combination of these three types of characters. The books in which these characters were written down also made use of binding methods imported from China, five types of which were used in parallel in Japan. Three of these binding methods were particularly common, and there was a status hierarchy among them, with a correlation between the contents of the work and the type of binding used. If we turn to examine the relationship between binding method and orthography, there is a clear tendency for scroll-format manuscripts to use lined paper for Chinese-character texts, but not for hiragana texts. A corresponding tendency can be found in codex-format printed books, which make use of a frame around the page for Chinese-character texts, but not in the earliest commercially-printed hiragana texts. This seems to be because while the frame used in Chinese-character texts serve to demonstrate the text is printed, hiragana printed books eliminated these in order to reproduce a manuscript format. Though some continuity remains, there is a difference in the respective attitudes displayed by manuscript and printed books towards the presence of lineation around the text. Thus, it is clear that in Japan the physical construction of the book held an intimate relationship, not just with the genre of writing it contained, but with its orthography as well.
