Proposing value‑based technology acceptance model: testing on paid mobile media service

Song‑yi Youn,이규혜 한국의류학회 2019 Fashion and Textiles Vol.6 No.1

Rapid growth of online media markets among world populations led to attempts by companies to exploit mobile services as part of business planning practices. Relatedly, this study examines adoption of paid mobile media service (i.e., Amazon Prime Video) as a source of new information and communication technology with online-offline integrated mobile services. The study’s main objective is to identify a technology acceptance model from the perspective of consumer experiences of value perceptions. This study proposed a value-based technology acceptance model, deriving from classic variables related to technology acceptance with regard to relevant consumer value perception literature. The proposed model examined effects of positive and negative experiences of value perceptions on consumers’ beliefs about paid service which explained future use of the paid service. Results indicated that consumers’ positive experiences—social, emotional, and functional values—derived from using mobile media services positively explained consumers’ belief of the usefulness of the paid mobile media service. Consumers’ negative experiences with technological barriers negatively influenced consumers’ beliefs with regard to the ease of use for paid mobile service, while price risk negatively influenced perceived usefulness. Consequently, consumers’ perceptions of ease of use and usefulness related to using the paid service positively influenced behavioral intention for continuous use of the paid mobile media service.

The purpose of this study was to examine self images as antecedents of clothing innovativeness and conformity. A survey questionnaire was made for the empirical research. 206 university students living in Seoul metropolitan area participated in the study. The data were analyzed using factor analysis, Chi-square, t-test, ANOVA, and stepwise regression. The self image measures were classified six factors (free, affirmative, self-centered, traditional, sensual, and feminine image). According to regression analysis, fashion innovativeness was affected by free, traditional, sensual image, and conformity was only influenced by traditional image. Respondents were classified into four groups by innovativeness and conformity scores; Low innovativeness/Low conformity group(LI/LC), Low innovativeness/High conformity group(LI/HC), High innovativeness/Low conformity group(HI/LC), and High innovativeness/High conformity group(HI/HC). For LI/LC consumers, innovativeness was affacted by the sensual self image. For LI/HC consumers, and innovativenss was affected by the feminine self image. The conformity of HI/LC were influenced by traditional self image.

Conformity and nonconformity in dress are the two driving forces that make diffusion of new styles. More fundamental personal attributes that affect individuality in dress are masculine or feminine sex roles. Researchers reported that little differences were found between men and women in terms of conformity values. Fashion and clothing products are related to hedonic shopping and major hedonic shopping orientations in clothing shopping behavior of college students were often reported. This study was aimed to empirically test the effect of personality traits of masculinity-femininity on nonconformity and conformity in dress; the effects of nonconformity and conformity on major hedonic shopping orientations. A survey questionnaire was developed for the empirical research. Data from 181 students were used for statistical analysis using structural equation modeling. A conceptual model with masculinity and femininity as two exogenous variables, two shopping orientations as endogenous variables and nonconformity-conformity as two mediating variables were analyzed. Results confirm the significant structural paths from masculinity to nonconformity, from femininity to conformity and from nonconformity to novelty-seeking and conformity to fashion seeking) were statistically significant. The results of this study suggested that The personality traits and shopping orientation were antecedents and consequences of nonconformity-conformity in dress and clearer relationships do exist in the flow.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

( Song Yi Youn ),( Kyu Hye Lee ) 한국의류학회 2012 한국의류학회지 Vol.36 No.6

This study took the conceptual framework of acculturation styles into the empirical investigation of international students in Korea. This research identifies the differences in acculturation styles, the characteristics of each segment, the effect of acculturation styles on clothing involvement (clothing involvement and risk probability), and the effect of cultural orientation values (individualism and collectivism) as covariates. The participants were international students attending a university located in Seoul. Data from 153 international students were used for statistical analysis. Respondents were grouped into four acculturation styles (integration, assimilation, separation, and marginalization). The assimilation group had the highest mean score of clothing interest. Cultural orientation values showed a significant covariate effect. With individualism as covariates, the main effect of acculturation styles on clothing interest was significant. In clothing product evaluation criteria, the integration group regarded design, fit and trend as most important. The marginalization group showed a mean score that was significantly lower in brand preference and satisfaction; however, the assimilation group had a mean score that was significantly higher.

People are exposed to diverse images and naturally find images to express themselves to others for personalsatisfaction. They present ideal images that they desire to obtain or actual images that they already have. People find differences between ideal images and actual images as well astry to overcome differences by managing appearance or purchasing fashion items. The congruence between real and ideal self-images and perceived body images stimulate clothing involvement or consumer confidence to influence fashion innovativeness and fashion opinion leadership. Fashion leaders are known for confidence when making buying decisions on new fashion products and are more likely to influence other consumers to buy new items. This study useda structural equation model to understand the influence of perceived self and body image on clothing involvement and consumer confidence as well as define how perceived images influence fashion leadership through clothing involvement and consumer confidence. The results of this study indicated that self-image congruence has a positive impact on social body image and personal body image. A positive influence of perceived body image on clothing involvement and consumer confidence was also detected. Fashion opinion leadership could be explained by clothing involvement and consumer confidence; however, fashion innovativeness could only be explained by consumer confidence.

IM-412 inhibits the invasion of human breast carcinoma cells by blocking FGFR-mediated signaling.

Jung, Seung-Youn,Yi, Jae Youn,Kim, Mi-Hyoung,Song, Kyung-Hee,Kang, Seong-Mook,Ahn, Jiyeon,Hwang, Sang-Gu,Nam, Ky-Youb,Song, Jie-Young National Hellenic Research Foundation 2015 Oncology reports Vol.34 No.5

<P>Triple-negative breast cancer (TNBC) is an aggressive cancer with a poor prognosis due to its epithelial???to-mesenchymal transition (EMT) phenotype. Cancer patients often experience several detrimental effects of cancer treatment, such as chemoresistance, radioresistance and the maintenance of cancer stem cells due to EMT. Thus, EMT signaling is considered to be a valuable therapeutic target for cancer treatment, and its inhibition is being attempted as a new treatment option for TNBC patients. Previously, we showed that 3-(2-chlorobenzyl)-1,7-dimethyl-1H-imidazo[2,1-f]purine???2,4(3H,8H)-dione (IM-412) inhibits transforming growth factor-관 (TGF-관)-induced differentiation of human lung fibroblasts through both Smad-dependent and??-independent pathways. In the present study, we examined the inhibitory effect of IM-412 on EMT pathways and invasiveness in TNBC cells since the TGF-관 signaling pathway is a typical signaling pathway that functions in EMT. IM-412 not only potently suppressed the migration and invasion of MDA-MB-231??cells, but also lowered the expression of mesenchymal markers and EMT-activating transcription factors in these cells. IM-412 inhibited the activation of several signaling proteins, including Smad2/Smad3, p38MAPK, Akt and JNK, and it also attenuated the phosphorylation of FGFR1 and FGFR3. Collectively, our findings suggest that the synthetic compound IM-412 suppressed the EMT process in MDA-MB-231??cells and thereby effectively inhibited the migration and invasion of these cancer cells. Thus, IM-412 could serve as a novel therapeutic agent for malignant cancers.</P>

Three known triterpenoids were isolated from MeOH extract of C. apiifolia (Ranunculaceae). Their structures were identified as oleanolic acid (1), ursolic acid (2), hederagenic acid (3) by comparison of their physicochemical and spectral data with the literature values. Among them, 2 was isolated for the first time from this plant. The isolated compounds were evaluated for their cytotoxicity against L1210, HL-60, SK-OV-3 tumor cell lines. All compounds 1-3 were shown good activities with $IC_{50}$ values ranging from 7.7 to $25.6\;{\mu}g/ml. This result suggests that triterpenoids 1-3 are main cytotoxic principles of this plant.
