诺曼.乔姆斯基所建立的转换生成理论,如“标准理论”、“扩展标准理论”、“管辖和约束理论”等被视为派生理论,而由Pollard and Sag(1987)提出的中心词驱动短语结构语法(HPSG)则是非派生的理论方法,被看作语法与语义学的综合理论。在建构上与“管辖约束理论”(简称“GB”)最重要的区别在于,中心词驱动短语结构语法理论没有任何转换生成的概念,并且它与“GB”所研究的层面不同,(HPSG)探讨的观点不在于语言结构中成分的移动问题,而在于结构共享。本文意在应用中心词驱动短语结构(HPSG)短语语法理论讨论韩语中敬语的一致性,其中有一套基于数据对于一致性的研究方法,它假设参与一致关系中的两个因素明确指出个别语言对象的信息。然而,本文是在语言中发现敬语的一致性,例如日语和韩语。在分析各类语用中的一致关系时,讨论语篇特征也是尤为重要的。韩语中敬语的建构是近似语用一致关系中的一部分,而非句法或语义的一致。

V2O5-WO3/TiO2 catalysts were prepared by impregnation method and in situ electrical conductivity measurements were carried out to investigate the reaction mechanism for ammonia SCR (selective catalytic reduction) of NOx. The electrical conductivity change with ammonia supply and the increase of electrical conductivity were mainly caused by reduction of the labile surface oxygen. The electrical conductivity change of catalysts shows close relationship with the conversion rate of NOx. Variation of conversion rate in atmosphere without gaseous oxygen also supports that the labile lattice oxygen is indispensable in the initial stage of the de NOx reaction. These results suggest that the liable lattice oxygen acts decisive role in the de NOx mechanism. They also support that De NOx reaction occurs through the Eley-Rideal type mechanism. The amount of labile oxygen can be estimated from the measurement of electrical conductivity change for catalysts with ammonia supply.

Photo-protective functions were investigated in phytoplankton assemblages at Kongsfjorden, Svalbard in spring, using their UV-absorbing compounds （mycosporine-like amino acids （MAAs））, xanthophyllpigments （diadinoxanthin （DD） and diatoxanthin （DT）） and〈beta〉-dimethylsulphoniopropionate （〈beta〉-DMSP）. The dominant phytoplankton species in the inner bay were dominated by Phaeocystis spp. and nanoflagellates, while the offshore waters were dominated by Thalassiosira spp. In the inner bay, UV- absorbing compounds and xanthophyll pigments exhibited higher ratios of MAA to chlorophyll a （MAA：chl a ratio）, and both DD and DT to chlorophyll a （DD：chl a ratio and DT：chl a ratio）, respectively. Thus, the photoprotective-pigrnents such as DD and DT appear to complement MAAs in the natural phytoplankton assemblage. However, the ratio of 〈beta〉-DMSP to chlorophyll a （〈beta〉-DMSP：chl a ratio） did not show a distinct spatial distribution according to environmental factors or interspecies differences. In this study, we found that photoprotective compounds occurred in a manner dependent on the phytoplankton species composition in Kongsfjorden Bay, where Phaeocystis is the dominant species.

We investigated the effects of the multilayer polymer-clay nanohybrid passivation films on the stability of pentacene organic thin-film transistors （OTFTs） exposed to air and UV irradiation. Well-ordered multilayer films were deposited by the spin-assisted layer-by-layer assembly method using photocrosslinkable poly（vinyl alcohol） with the N-methyl-4（4＇-formylstyryl）pyridinium methosulfate acetal group （SbQ-PVA） and Na＋-montmorillonite in a water-based solution process. When photocrosslinked, these SbQ-PVA/clay multilayers were found to serve as excellent barriers to 02 and UV-light. Moreover, when used as passivation layers, they enhanced the stability of pen- tacene OTFT devices exposed to air and UV radiation.

The expression of recombinant proteins in microorganism frequently leads to the formation of insoluble aggregates, inclusion bodies （IBs）. Thus, the additional in vitro protein refolding process is required to convert inactive IBs into water-soluble active proteins. This study investigated the effect of sulfur residue and hydrophobicity of imidazolium-based room temperature ionic liquids （RTILs） on the refolding of lysozyme as a model protein in the batch dilution method which is the most commonly used refolding method. When lysozyme was refolded in the refolding buffer containing [BF4]-based RTILs with a systematic variety of alkyl chain on cations varying from two to eight, less hydrophobic imidazolium cations having shorter alkyl chains were effective to facilitate lysozyme refolding. Compared to the conventional refolding buffer, 2 times higher lysozyme re- folding yield was obtained in l-ethyl-3-methylimidazolium tetrafluoroborate （[EMIM][BF4]） containing refolding buffer. The refolding yield of lysozyme was even more increased by 2.5 times when 1-butyl-3-methylimidazolium methylsulfate （[BMIM][MS]） containing sulfur residue on anion was used. The sulfur residue in [BMIM][MS] is supposed to improve the refolding yield of lysozyme which has 4 intrarnolecular disulfide bonds. For dilution-based refolding of lysozyme, the opti- mum concentrations of RTILs in refolding buffer were found to be 1.0 M [EMIM][BF4] and 0.5 M [PMIM][MS], respectively. The optimum temperate for dilution-based refolding of lysozyme with RTILs was 4 ℃.

Subcellular organelle-specific nanoparticles for simultaneous tumor targeting, imaging, and drug delivery are of enormous interest in cancer therapy. Herein, we report a selective mitochondria-targeting probe 1, which was synthesized by incorporating a triphenyl phosphine with a cyanostilbene and a long alkyl chain moiety. Probe 1 was found to display fluorescence via aggregation-induced emission （AIE）. The low molecular-weight cyanostilbene-based probe 1, with and without an anticancer drug, formed a narrow homogeneous nanorod with ca. 110 nm of length or nanopartides with ca. 20 nm diameter in aqueous media. The self-assembled cyanostilbene nanoparticles （N1） selectively accumulated in the mitochondria of cancer cells and emitted fluorescence. N1 was also able to deliver an anticancer drug, doxorubicin （DOX）, to the mitochondria with high efficiency. More importantl~ N1 exhibited highly selective cytotoxicity for cancer cells over normal cells. The great potential applications of this self-assembled nanoparticle to biological systems result from its ability to aggregate in the mitochondria. This aggregation led to a significant increase in the generation of intraceUular reactive oxygen species and to a decrease in the mitochondrial membrane potential in cancer cells. Furthermore, tumor tissue uptake experiments in mice proposed that the self-assembled N1 had the ability to internalize and deliver the anticancer drug into tumor tissues effectively. Moreover, both N1 and Nl-encapsulated doxorubicin （N1-DOX） effectively suppressed tumor growth in a xenograft model in vivo. Taken together, our findings indicate that applications of N1 as a mitochondrial targeting probe, drug delivery platform, and chemotherapeutic agent provide a unique strategy for potential image-guided therapy as well as a site-specific delivery system to cancer cells.
