The purpose of this study is to investigate the influence of WeChat s characteristics on the perceived relationship benefits in WeChats official accountof Korean fashion brand, and also to grasp the influence of perceived relationship benefits on brand trust and word-of-mouth intention. The data on this study were collected with a questionnaire method in July, 2018 and 185 usable data were used for analysis. The subjects of this study were Chinese customers who have an experience with using a WeChat official account of Korean fashion brands. The collected data were carried out for factor analysis, independent sample t-test, and regression analysis by using SPSS Ver. 24.0 program. The result of this study is as follows. First, WeChat characteristics were classified into four factors such as usefulness, freshness, familiarity, and accessibility and three factors of relational benefits such as informative, psychological and economic benefit were extracted. Secondly, Four WeChat characteristics positively affected informative benefit. However, psychological benefit was influenced by only usefulness and familiarity, and familiarity was found to be the only characteristic of WeChat which had a significant effect on social benefit. Third, The three perceived relationship benefits in the Korean fashion brand account significantly influenced brand trust, but psychological benefit was not related to word-of-mouth intention.

The purpose of this study is to examine the effects of clothing and cosmetics consumption value on the use of information source and selection of purchase channel. In addition, this study aims to compare Korean consumers and Chinese consumers in terms of consumption value, information source, and purchase channel. An online survey was conducted in respondents in their 20s to 30s, and 440 Korean responses and 390 Chinese responses were analyzed using SPSS 24.0. The results showed that all six clothing consumption values significantly influenced the use of online clothing information source and four values except for economic and brand-conspicuous values had an effect on the offline source. Four cosmetics consumption values except for economic value had significant effects on the use of online cosmetics information source and all five values significantly influenced the offline source. The online information source had stronger effects on the purchase channel than the offline source in terms of both clothing and cosmetics. Korean and Chinese consumers significantly differed in terms of clothing consumption values except for hedonic and brand-conspicuous values and in all five cosmetics consumption values. They also differed in all information sources of clothing and cosmetics and purchase channels except for brand specialty store of clothing.
Experimental studies on gasification of the Shenmu coal char with CO2 at elevated pressures

The gasification rates of Shenmu coal chars with CO2 were experimentally studied with a pressurized thermo- gravimetric analyzer (PTGA). Shenmu coal is a typical Chinese coal, and the coal char was prepared by a fixedbed reactor in nitrogen at 900 oC. The experiments were carried out in the dynamic heating segments from 750 oC to 1,000 oC, and the reaction pressure increased from 0.1MPa to 3.1MPa with pure CO2. The external diffusion resistances were minimized by increasing the flow rates and decreasing the thickness of sample layer before the test, to ensure the reactions were under kinetic control. The results show that the gasification rates increase proportionally to the 0.1 power of the CO2 partial pressure. The unreacted-core shrinking model was applied to predict the reaction rate by changing the molar fraction of CO2 at 0.6Mpa and 1.6Mpa total pressures, which showed a good match with experimental data.
Identification a novel de novo RUNX2 frameshift mutation associated with cleidocranial dysplasia

Background: Cleidocranial dysplasia (CCD) is a rare genetic disorder affecting bone and cartilage development. Clinical features of CCD comprise short stature, delayed ossification of craniofacial structures with numerous Wormian bones, underdeveloped or aplastic clavicles and multiple dental anomalies. Several studies have revealed that CCD development is strongly linked with different mutations in runt-related transcription factor 2 (RUNX2) gene. Objective: Identification and functional characterization of RUNX2 mutation associated with CCD. Methods: We performed genetic testing of a patient with CCD using whole exome sequencing and found a novel RUNX2 frameshift mutation: c.1550delT in a sporadic case. We also compared the functional activity of the mutant and wild-type RUNX2 through immunofluorescence microscopy and osteocalcin promoter luciferase assay. Results: We found a novel RUNX2 frameshift mutation, c.1550delT (p.Trp518Glyfs*60). Both mutant RUNX2 and wild-type RUNX2 protein were similarly confined in the nuclei. The novel mutation caused abrogative transactivation activity of RUNX2 on osteocalcin promoter. Conclusions: We explored a novel RUNX2 deletion/frameshift mutation in a sporadic CCD patient. This finding suggests that the VWRPY domain may play a key role in RUNX2 transactivation ability.
