With the development of the e-commerce market, consumers shop online through the internet, and the scale of online shopping increases rapidly, especially through the use of smart phones. With the growth of online shopping in China, consumers demand for higher quality products and seek for personalization. Recently, new media such as mobile, internet and social media based on communication technology have grown rapidly. Meanwhile, the popularity of e-commerce around the world has a great impact on people’s lifestyle and consumption habit. With the growth of online shopping in China, consumers demand for higher quality products and seek for personalization. The main reason why Chinese consumers buy Korean fashion brands is because of the celebrity endorsement. According to the results, First, in brand characteristics, brand image, brand awareness, perceived quality and product diversity have prominent influence on consumer’s satisfaction degree and repurchasing intention.. Second, among consumer characteristics, fashion involvement, innovation and economy have prominent influence on consumer’s satisfaction degree and repurchasing intention. Third, impulsiveness in consumer characteristics has no prominent influence on satisfaction degree,Forth, the consumer’s satisfaction degree of fashion brands has significant influence on repurchasing intention.

An Access Control Model for Mobile Networks based on the Non-zero-sum Game Theory

Yi-xuan Zhang,Jing-sha He,Ruo-hong Liu 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.4

Access control is the basic of information security. It is always used to protect sensitive information and critical resources from malicious attacks. But the traditional access control models are more adapt to closed network environment. And there are more and more unknown threats and attacks in the open networks, especially the mobile networks. To solve this problem, we propose a new access control model which is applicable to the open mobile networks by using non-zero-sum game theory in this paper. The model is composed by six modules: access evaluation module, access permission determination module, non-zero-sum game theory analysis module, decision-making module, result evaluation module, access feedback module and a prior information database. And in this model, the subjects will choose to be more honest when they make access requests because they all want to get more permission next time. Then we do some experiments to prove this fact.

Objectives. Reactive oxygen species in the stria vascularis (SV) of the cochlea may be involved in the pathogenesis of sen-sorineural hearing loss. However, the effects of oxidative stress on SV endothelial cells (SV-ECs) remain largely un-known, and no feasible in vitro cell culture model exists for the functional study of SV-ECs. Methods. We isolated primary SV-ECs from the SV of neonatal mice. The apoptosis-reducing effects of fibronectin in SV-ECs cultured with serum-free medium were determined using β-galactosidase staining and flow cytometry. SV-ECsincubated in serum-free medium were treated with various H2O2 concentrations to evaluate the effects of H2O2 ontheir viability. The secretome of SV-ECs treated with or without H2O2 (100 μM or 500 μM) was analyzed using high-resolution mass spectrometry. The function of the SV-EC secretome was evaluated by a macrophage assay. Results. We successfully isolated and characterized the SV-ECs. Treatment with H2O2 at concentrations up to 500 μM for2 hours and further incubation with serum-free medium in plates precoated with fibronectin showed no significanteffect on apoptosis. Compared to the control SV-ECs, the amount of differential proteins in the secretome of SV-ECsstimulated with 500 μM H2O2 was much higher than in those treated with 100 μM H2O2. Kyoto Encyclopedia ofGenes and Genomes and Gene Ontology analyses suggested that the proteins differentially expressed in SV-ECstreated with 500 μM H2O2 were involved in the regulation of multiple signaling pathways and cellular processes. Thesecretome of H2O2-stimulated SV-ECs exhibited significant pro-inflammatory effects on macrophages. Conclusion. We successfully established an in vitro serum-free culture method, identified the differential proteins releasedby oxidative stress-induced ECs and their functions, and revealed the pro-inflammatory effects of the secretome ofH2O2-stimulated SV-ECs. Therefore, SV-ECs might elicit immunoregulatory effects on bystander cells in the microen-vironment of oxidative stress-induced cochlea, especially cochlear macrophages.

2010년대 대학 심벌마크 리뉴얼 전후의 선호도 비교 및 평가모형 연구

저우이쉬안 ( Yi-xuan Zhou ),김태완 ( Tai-wan Kim ) 한국디자인트렌드학회 2021 한국디자인포럼 Vol.26 No.2

연구배경 21세기 교육 글로벌화, 수험생 감소, 대학설립 자율화 등 교육환경이 급변하면서 대학들은 학생유치, 사회지원, 정부재정에 대한 경쟁이 치열해지고 있다. 국내 대학들이 이미지 혁신을 통해 경쟁력을 강화하기 위해 심벌마크 리뉴얼을 핵심으로 하는 대학 아이덴티티 혁신 전략을 펴고 있다. 하지만 리뉴얼 열풍 속에서 실제 효과에 대한 평가 메커니즘이 없기 때문에 회의적인 목소리가 나오고 있다. 따라서 최근 대학 심벌마크 리뉴얼 전후의 선호도 비교 및 평가모형이 필요하다. 연구방법 본 연구는 독립표본 t-검정을 이용하여 2010년~2020년 사이 심벌마크를 리뉴얼한 대학 16개교의 전후 비교 사례 32건 중 각 평가요인과 선호도에 대한 비교와 평가를 진행하였으며, 선형 회귀분석을 이용하여 각 평가요인이 대학 심벌마크의 선호도에 미치는 영향을 검증하고 회귀 방정식을 근거로 대학 심벌마크 리뉴얼의 평가모형을 구축한 것이다. 연구결과 2010년대 대학 심벌마크 리뉴얼 사례의 회귀 방정식을 바탕으로 역사와 전통성, 독창성, 심미성, 지속성, 식별성이 각각 16.5%, 16.4%, 15.6%, 23.6%, 27.9%로 대학 심벌마크 리뉴얼의 평가모형을 구축하였다. 결론 2010년대 대학 심벌마크 리뉴얼 후 사례는 리뉴얼 전 사례에 비해 지속성과 식별성이 크게 향상됐고 심미성과 독창성은 약간 향상됐지만 역사와 전통성은 크게 떨어졌다. 미래의 대학 심벌마크 리뉴얼 프로젝트에서는 대학 심벌마크의 지속성과 식별성을 유지하면서 대학의 문화와 역사를 상징하는 조형 요소를 간결화해 대학 심벌마크의 역사와 전통성을 높이고 이어가야 한다. Background With the dramatic changes in the educational environment in the 21st century, universities are increasingly competing for student retention, social support and so on. In order to strengthen their competitiveness through the innovation of image, domestic universities are implementing the innovation strategy of university identity which takes the renewal of symbol mark as the core. However, in the upsurge of renewal, because there is no evaluation mechanism for the actual effect, so there are voices of skepticism. Therefore, it is necessary to compare the degree of preference before and after the update of university symbol marks in recent years, and build an evaluation model. Methods This study compared and evaluated each evaluation factor and preference among 32 before and after comparison cases of 16 universities renewed between 2010 and 2020 using independent sample t-test, using linear regression to verify the impact of each evaluation factor on the preference of university symbol. Result Based on the regression equation, the evaluation model of University symbol mark renewal is constructed, which is 16.5%, 16.4%, 15.6%, 23.6%, and 27.9% respectively in history and traditional, originality, aesthetic, sustainability and identification. Conclusion Compared with the cases before the renewal, the cases after the renewal of university symbol marks from 2010 to 2020 have a great improvement in sustainability and identification, while the originality and aesthetic have been improved, but the historical and traditional characteristics have decreased significantly. In the future renewal project, we should keep the sustainability and identification of the University symbol mark, and simplify the design elements that symbolize the culture and history of the University, so as to enhance and continue the history and traditional of the University symbol mark.

Autophagy Involvement in Olanzapine-Mediated Cytotoxic Effects in Human Glioma Cells

Wang, Yi-Xuan,Xu, Shu-Qing,Chen, Xiang-Hui,Liu, Rui-Si,Liang, Zhong-Qin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.19

The aim of this study was to investigate the effects of olanzapine on growth inhibition as well as autophagy in glioma cells in vitro and in vivo. The proliferation of both LN229 and T98 glioma cells, measured by MTT assay, was suppressed in a concentration-dependent and time-dependent manner. Moreover, apoptosis of both cells was significantly increased with the treatment of olanzapine as evidenced by increased Bcl-2 expression, Hoechst 33258 staining and annexinV-FITC/PI staining. Olanzapine treatment also enhanced activation of autophagy with increased expression of LC3-II, expression of protein p62, a substrate of autophagy, being decreased. The growth inhibition by olanzapine in both glioma cell lines could be blocked by co-treatment with 3-MA, an autophagy inhibitor. Furthermore, olanzapine effectively blocked the growth of subcutaneous xenografts of LN229 glioma cells in vivo. The increased level of protein LC3-II and decreased level of p62 followed by a decreased level of Bcl-2, suggesting that autophagy may contribute to apoptosis. In addition, reduced proliferation of glioma cells was shown by a decrease of Ki-67 staining and increased caspase-3 staining indicative of apoptosis in mouse xenografts. These results indicated that olanzapine inhibited the growth of glioma cells accompanied by induction of autophagy and apoptosis both in vitro and in vivo. Olanzapine-induced autophagy plays a tumor-suppressing role in glioma cells.

Zhou, Yi-Li,Zhang, Wei,Gao, Er-Li,Dai, Xuan-Xuan,Yang, Han,Zhang, Xiao-Hua,Wang, Ou-Chen Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.4

Background and Objective: The optimal resection extent for clinically unilateral papillary thyroid microcarcinoma (PTMC) remains controversial. The objective was to investigate risk factors associated with occult contralateral carcinoma, and put emphasis on the predictive value of preoperative BRAF mutation. Materials and Methods: 100 clinically unilateral PTMC patients all newly diagnosed, previously untreated were analyzed in a prospective cohort study. We assessed the T1799A BRAF mutation status in FNAB specimens obtained from all PTMC patients before undergoing total thyroidectomy (TT) and central lymph node dissection (CLND) for PTMC. Univariate and multivariate analyses were used to reveal the incidence of contralateral occult cancer, difference of risk factors and predictive value, with respect to the following variables: preoperative BRAF mutation status, age, gender, tumor size, multifocality of primary tumor, capsular invasion, presence of Hashimoto thyroiditis and central lymph node metastasis. Results: 20 of 100 patients (20%) had occult contralateral lobe carcinoma. On multi-variate analysis, preoperative BRAF mutation (p = 0.030, OR = 3.439) and multifocality of the primary tumor (p = 0.004, OR = 9.570) were independent predictive factors for occult contralateral PTMC presence. However, there were no significant differences between the presence of occult contralateral carcinomas and age, gender, tumor size, capsular invasion, Hashimoto thyroiditis and central lymph node metastasis. Conclusions: Total thyroidectomy, including the contralateral lobe, should be considered for the treatment of unilateral PTMC if preoperative BRAF mutation is positive and/or if the observed lesion presents as a multifocal tumor in the unilateral lobe.
