This paper investigates the nature of Japanese argument cluster (Steedman 2000b). Based on Combinatory Categorial Grammar, a type-raising analysis of case particles which captures some aspects of the information structure in Japanese is discussed, including contrastive interpretation of coordination, wh-constructions, and some theme and rheme-related grammatical phenomena. These observations offer further support for the study of syntax, semantics, and phonology interface and the earlier analysis of English information structure.

This study is concerned with the stability of liquid crystal forming emulsifier with localized depend on change of pH using liquid crystal forming agent of advanced company. The liquid crystal emulsifying agent was localized using Sugar Crystal-LC (bio-tech Co., Ltd., Korea), and comparative samples were measured by using Nikkomulese-LC (Nikko Camicarls, Japan) and Alacel-LC (Croda Camicarls, UK). Liquid crystal formation was confirmed microscopically to show the formation of liquid crystal structure at acidic (pH=4.2), neutral (pH=7.0) and alkaline (pH=11.7). The particles of the liquid crystal were observed with a polarizing microscope according to the stirring speed. The stirring time was all the same for 3 minutes with a homo-mixer, and the stirring speed was increased to 2500 rpm, 3500 rpm and 4500 rpm to observe the liquid crystal state. As a result, it was found that the Korean surfactant was more stable and clear liquid crystal structure was formed than the two foreign acids. In the case of the UK in acid zone, the emulsion particle size was uniform and unstable. In the case of Japanese surfactant, it has similar structure and performance to those of localized Korean. It was found that Korean surfactant had superior emulsifying performance in acid zone compared with foreign products. It is possible to develop various formulations such as liquid crystal cream, lotion, eye cream, etc. using Sugar Crystal-LC emulsifier as an application cosmetic field, and it is expected that it can be widely applied as emulsifying technology for skin care external application in the pharmaceutical industry and the pharmaceutical industry as well as the cosmetics industry.
