LIUYUN 중국어문학연구회 2017 중국어문학논집 Vol.0 No.107
This paper investigates the form “ba/bei…gei VP” in contemporary Chinese language, which is endowed with many particularities. Firstly, this paper analyzes the overlap principle of the internal semantics of the form “ba/bei … gei VP” from the perspectives of semantic overlap and syntactic integration. The semantics of this form includes two categories of semantic overlap, “semantic overlap of similar meanings” and “semantic overlap of opposite meanings”. This form is also strengthened pragmatically due to the semantic overlap. on this question and idea. Second, this paper discusses from the syntactic point of view the type and characteristics of the VP in this form, and the characteristics of the negation form and other derived forms of it. Finally, the paper then goes on to investigate the syntactic generation of “ba/bei…gei VP” from the perspectives of semantics and generative syntax. It is believed that “ba/bei…gei VP” is derived from “NP gei VP” and “gei NP VP” through semantic and syntactic evolution. Since “gei” in sentences plays the role of introducing implicit arguments, when an argument is added, “ba” and “bei” are thus needed to mark and introduce the new argument. The form is in turn further extended and the “ba/bei … gei VP” form therefore takes the shape.

LIUYUN,김현철 중국어문학연구회 2018 중국어문학논집 Vol.0 No.109
The morphological reduplication of prepositions is synchronic, prescribing the combination of morphemes on the basis of word-formation rules. However, as for conditions in which reduplications make sense, semantics which are appropriate and causes which have led to the formation of syntaxes, the lexical diachronic evolution and development have the final say. This paper adopted the source-tracing approach to investigate “自, 从, 打, 由” and their respective reduplicated phrases in terms of the following three steps: semantic evolution, semantic models and reduplicated mechanisms. Firstly, it had adopted the method of reanalysis and grammatical path to parse the semantic evolutions of the four monosyllabic prepositions and how the derivational senses generated as well as how the implied semantic features embodied themselves on the syntactic level. Second, based on a full understanding of monosyllables and semantic features and functions of reduplicated preposition, it re-categorized the propositions and their corresponding features and unearthed the relations between semantic coverages and semantic features, which involved mutual selection, blending and reduplication.

This study focuses on the superimposed prepositions in modern Chinese, like “自从”, “自打”, “打从”, “从打”, “由打”. These prepositions is a special category of parallel superimposed prepositions in modern times Chinese. They are composed by monosyllabic prepositions with same or similar semantic meanings. These monosyllabic prepositions merge together and complement each other, so as to become a new category of disyllable prepositions with same semantic meaning. Chapter Two conducts a comparative analysis on superimposed prepositions and their superpositions on synchronic plane. Comparative analysis mainly takes three perspectives as below: first, the uses of prepositions are summarized from the perspective of semantic function. According to the semantic feature of the prepositions introducing the objects, we can categorize the prepositions into 4 types: a) time start, b) place start, c) scope start, d) origin. In each type of preposition, superimposed prepositions and monosyllabic prepositions have huge difference in the choice of object and VP. Second, the features of each preposition’s word order in sentence are analyzed, The syntactic position of preposition. The analysis focuses on the differences of before superposition and after superposition and also where these differences stem from. Finally, the topic function of superimposed prepositions is discussed. Almost all the superimposed prepositions can be place at the beginning of a sentence as a sub-clause or a preposition guide to introduce the objects followed, but they can’t be the topic in all the circumstance. Chapter Three explores the morpheme’s order within the superimposed prepositions based on the diachronic level. The morphemes’ order in a superimposed preposition are not random arrangement, but based on certain principle. Morphemes are mainly arranged in two ways: fixed order and temporary order, which is influenced by syntax, semantics, rhythm, etc. Fixed order is mainly decided by the lexicalization and part of speech. Temporary order is influenced greatly by the semantic meaning, and meeting the requirement of rhythm and avoiding repetition also influence the temporary order.

Sample Preparation and Stability of Human Serum and Urine Based on HPLC-DAD for Metabonomics Studies
Liu, Yun,Sun, Xiaoming,Di, Duolong,Feng, Yuxiang,Jin, Fengling Korean Chemical Society 2012 Bulletin of the Korean Chemical Society Vol.33 No.7
Many literatures focus on the biological relevance and the identification of biomarkers for disease activity assessment while less attention has been paid to the development of standard procedures for sample preparation and storage based on liquid chromatography technique. The influencing factors including protein precipitation, storage temperature, storage time, and reconstitution by ultra pure water were analyzed employing HPLC-DAD. The effects were investigated from five participants over three months by principal components analysis (PCA) and the values of percent changes (PC). The samples with protein precipitation might slow the rate of bacterial enzymatic conversion. After protein precipitation, the average PC of urine samples ($0.136{\pm}0.013$, n = 5) is relatively less than that of the serum samples ($0.173{\pm}0.026$, n = 5) for three months. Minimal effects on metabolic profiles of serum and urine (PC < 0.15) are reasonable for metabolomic studies after protein precipitation and storage at $-20^{\circ}C$ for two months.

Origins of the Stokes Shift in PbS Quantum Dots: Impact of Polydispersity, Ligands, and Defects
Liu, Yun,Kim, Donghun,Morris, Owen P.,Zhitomirsky, David,Grossman, Jeffrey C. American Chemical Society 2018 ACS NANO Vol.12 No.3
<P>Understanding the origins of the excessive Stokes shift in the lead chalcogenides family of colloidal quantum dots (CQDs) is of great importance at both the fundamental and applied levels; however, our current understanding is far from satisfactory. Here, utilizing a combination of <I>ab initio</I> computations and UV-vis and photoluminescence measurements, we investigated the contributions to the Stokes shift from polydispersity, ligands, and defects in PbS CQDs. The key results are as follows: (1) The size and energetic disorder of a polydisperse CQD film increase the Stokes shift by 20 to 50 meV compared to that of an isolated CQD; (2) Franck-Condon (FC) shifts increase as the electronegativities of the ligands increase, but the variations are small (<15 meV). (3) Unlike the aforementioned two minor factors, the presence of certain intrinsic defects such as V<SUB>Cl</SUB><SUP>+</SUP> (in Cl-passivated CQDs) can cause substantial electron density localization of the band edge states and consequent large FC shifts (100s of meV). This effect arising from defects can explain the excessive Stokes shifts in PbS CQDs and improve our understanding of the optical properties of PbS CQDs.</P> [FIG OMISSION]</BR>

Reforming Tar from Biomass Gasification using Limonite and Dolomite as Catalysts
Kim, Hee-Joon,Kunii, Hiroo,Li, Liuyun,Shimizu, Tadaaki,Kim, Lae-Hyun The Korean Society for Energy 2011 에너지공학 Vol.20 No.4
In this study, Catalytic reforming with vapor and biomass gasification was simultaneously performed in a same fixed bed reactor at $600-800^{\circ}C$. Light gases were produced from reformation of the tar (fuel gases) in biomass gasification by using limonite and dolomite, as catalysts. Hydrogen and carbon dioxide are main components in light gases. Hydrogen yields increased with temperature increasing in the range of $650-800^{\circ}C$, because the water shift reaction was promoted by catalyst. The yield of hydrogen gas was increased about 160% under catalyst with the mixture of limonite and dolomite comparing to limonite only.
