Congenital heart disease is now estimated to be the most prevalent chronic illness in children. The overall purpose of study is to enhance our understanding of mother's perception of family stress, perceived social support, and coping who has a child newly diagnosed with congenital heart disease. In this investigation, the relationship between family stress, perceived social support, and coping within the context of a acute, non life- threatening chronic illness in the situation of newly diagnosed as Rolland's typology of chronic illness. The study employed data from a subset of a large longitudinal study, children's chronic illness: parents and family adaptation conducted by M. McCubbin (5 R29 NR02563) which was funded by the NIH. The subject for this study were 92 mothers who have a child under age 12 who was newly diagnosed with congenital heart disease within the last 3-4 months. Results form correlational and regression analysis revealed that perceived social support operated as a resiliency factor between family stress and coping of mothers. Child and family characteristics appeared to be important predictors of perceived social support and mother's coping. Therefore, the findings provide an incremental contribution to the explanation of effects for perceived social support and may challenge resiliency model in previous literature. Further, these findings suggest that perceived social support and coping are both influencing in the resiliency of relatively high risk groups of families who has a child with congenital heart disease.

As the fast development of information technology (IT), abundant attractive alternatives have showed up and challenged to the traditional information technology (IT). Cloud services, the hottest representative among these alternatives, has attracted the attention from all walks of life. Considering the diversity of cloud services, this study attempts to find out the important factors affected on individual's switching intention from incumbent IT to cloud services mainly based on two-factor theory (switching enablers and switching inhibitors) and explore the direct influences of these factors on individual's switching intention. According to our findings, individual's switching intention to cloud services is not only positively influenced by switching enablers but also negatively influenced by switching inhibitors. All the switching enablers in this study (perceived omnipresence, perceived collaboration support and perceived compatibility of cloud services) have positively significant influences on individual's switching intention as well as the switching inhibitors (usage habit of incumbent IT and perceived risk of cloud services) have negatively significant influences on individual's switching intention. It's noteworthy that satisfaction of incumbent IT has insignificant influence on individual's switching intention in this study. Moreover, as we expected, both social influence and personal innovativeness have significant influences on the generation of individual's switching intention.

Stepping into the technological boom time, Vietnam has integrated into the trends of using Fintech applications as a new means of payment. This article evaluates the relationship between perceived security (including service security and platform security), knowledge, confirmation, perceived usefulness, satisfaction, attitude and lastly enterprise's images regarding the service and continuous intention to use Fintech services. The survey results of 352 Vietnamese customers using Fintech services, reliability test and extended post-acceptance model (EPAM) which is based on PAM and ECT models. From the survey, we further found out that perceived security (BSS) has no direct impact on continued intention to use, while perceived security (BSS) has positive impact on confirmation (CON), similarly, perceived usefulness (PU) and user's satisfaction (SES). Knowledge of the Mobile Fintech payment service (KNOW) has a positive impact on perceived security (BSS). Confirmation (CON) has a positive influence on perceived usefulness but in the meanwhile it has created a negative impact on user's satisfaction (SES). From the survey it can also tell that user's attitude (ATT) and enterprise image (IMG) both have a positive impact on continual intention to use Fintech services. From the research results, we also propose some recommendation to enhance the continual intention to use Fintech services in Vietnam.

This study aims to understand the effects of perceived usefulness, perceived ease, and expected matching on user satisfaction and continuous use intention for the learning management system (LMS). To this end, an online survey was conducted on K University students located in Chungcheongbuk-do, and 488 data were analyzed and utilized. First, it was found that the expected match of the learning management system had an effect on perceived usefulness and perceived ease. Second, it was found that perceived usefulness, perceived ease, and expected matching had an effect on user satisfaction. Perceived usefulness, user satisfaction and perceived ease of use were found to have an effect on the intention to continue using. It can be seen that the improvement of the quality of the university education system has an effect on the improvement of learners' learning effects and satisfaction. Accordingly, it is necessary to seek various ways to continuously manage the quality of the learning management system.

This study examines the impact of live commerce characteristics on customer responses in the ELM perspective. Based on ELM, the central route is composed of information completeness, accuracy, and currency, and the peripheral route is composed of streamer credibility, streamer reputation, social presence, and system quality. An online survey of female customers aged 20 to 49 who have purchased beauty products through live commerce within the past three months was conducted. The results demonstrate that information completeness and information currency exert significant impact on perceived usefulness and enjoyment. Social presence and system quality also exert significant impact on perceived usefulness and enjoyment. Moreover, perceived usefulness and enjoyment had significant impact on behavioral intention. The effect of information completeness on perceived usefulness and enjoyment was much stronger for high product involvement groups. Furthermore, the effect of streamer reputation on perceived enjoyment was much stronger for high product involvement groups. In contrast, the effect of social presence on perceived usefulness and enjoyment was much stronger for low product involvement groups. This study suggests theoretical implications for applying ELM to live commerce and practical implications for differentiated live commerce marketing strategies.

This study investigate the role of consumer's perception of quality in new technology adoption process in China which is given little attention in the field of Information System and Communication Technology. Here, we developed a simple model in the level of consumer perception by exploring the antecedent of perceived quality. Three factors are introduced as determinants of perceived quality: perceived usefulness, perceived risk and trialability. An empirical study is conducted with analysis of the adoption mechanism of a new innovative product. Data analysis results support some of our proposed hypotheses. It indicates that perceived quality is positively related to the adoption intention and fully mediates the relationship between triablility and purchase intention. And we conclude that a product's perceived quality plays an important role in adoption intention. And what makes Chinese customers perceive product's quality good is a trialability of a product. This suggests that when market managers plan to launch products in China, they need to craft an effective strategy based on the market system of the consumer especially understanding the consumers' critical factor for adopting a new product. Chinese are more interested to purchase a product with free trial and free experiential period, therefore, suggesting an advertisement highlighting the trialability of a product is possible in China.

Perceived age is defined as age estimated based on physical appearance. Perceived age is an important indicator of the overall health status of the elderly. This is because people who appear older tend to have higher rates of morbidity and mortality than people of the same chronological age. Although perceived age is an important indicator, there is a lack of objective methods to quantify perceived age. In this paper, we construct a quantified perceived age model from face images using a convolutional neural network. The face images are enlarged to super-resolution and the skin, an important feature in perceived age, is made clear. Moreover, through Tanh-polar transformation, the central area of the face occupies a relatively larger area than the boundary area, helping the neural network better recognize facial skin features. The experimental results show mean absolute error (MAE) of 6.59, showing that the proposed model is superior to existing method.

The purpose of this study was to understand effects of culinary staff's technology kitchen system upon perceived ease of use, usefulness, attitude, and job performance in the foodservice industry. Based on a total of 387 samples obtained from empirical research, this study reviewed the reliability and fitness of the research model and verified a total of four hypotheses using the Amos program. The hypothesized relationships in the model were tested simultaneously using a structural equation model (SEM). The proposed model provided an adequate fit to the data, ${\chi}^2$=226.501 (df=85), p<.001, CMIN/df 2.665, RMR .066, GFI .927, NFI .926, IFI .952, TLI .941, CFI .952. The results show that culinary staff's perceived ease of use(${\beta}$=.534) had a significant positive effect on perceived usefulness. Also, perceived ease of use (${\beta}$=.350) and perceived usefulness (${\beta}$=.297) had a positive significant effect on attitude. Further, attitude (${\beta}$=1.647) had a significant positive effect on job performance. Limitations and future research directions are also discussed.

The use of mobile payment services has recently increased in South Korea. Mobile payments allow consumers to purchase items digitally, using a mobile card in an app affiliated with a payment service. This study explores the predictors of intention to adopt mobile payment services. The study employed an A(affective)-B(behavioral)-C(cognitive) model with two antecedent variables: cognitive (perceived usefulness, perceived risk, perceived ease of use, and perceived herding behavior) and affective (satisfaction with the status quo, innovation resistance) responses. An online survey of 405 non-users of mobile payment services aged 20 to 49 years was conducted. The study used SPSS 23.0 for descriptive analysis and Amos 23.0 for confirmatory factor analysis and structural equation modelling. The results are as follows. First, perceived usefulness, perceived risk, and perceived herding behavior significantly influenced innovation resistance. Second, perceived herding behavior significantly influenced subjective norms. Third, innovation resistance and subjective norms significantly influenced the intention to adopt mobile payment services. The findings suggest that the A-B-C model can be useful in understanding consumers' adoption and resistance behaviors and that cognitive and affective responses are important antecedent variables affecting the decision to adopt mobile payment services.
