Electronic Commerce or e-commerce implies such an industry where goods and services are bought and sold over electronic systems. This is rapidly growing sectors in Bangladesh which influence local and international trade. Government of Bangladesh has also initiated quite a good number of measures for the expansion of e-commerce. However, low adoption of e-commerce is not uncommon in Bangladesh. The objective of this study is to determine the factors that influence the adoption of e-commerce services in Bangladesh. Extended version of Technology Acceptance Model (TAM) is envisaged as the theoretical backbone of the study. Reliability analysis using Cronbach's Alpha test indicates that the research model is internally consistent. The study reveals that 35 percent of respondents became interested in e-commerce services from advertisement on Internet or other electronic media. The findings of the study shows that all the four constructs, namely-Computer Self Efficacy, Perceived Credibility, Perceived Usefulness and Perceived Ease of Use have significant effect on the adoption of e-commerce. The study has also demonstrated that Perceived Usefulness appeared as the most important factor in describing user's adoption of e-commerce.

This study aimed to determine the effects of self-esteem, appearance satisfaction, and satisfaction in their major on the employment stress of nursing college students. The subjects were 194 students from four colleges of nursing in P-province in Korea. Data were collected from self-administered questionnaires, t-test, ANOVA, Pearson's and Spearman's correlation coefficients. Multiple regression with dummy variables was used for statistical analysis of the data. The results revealed the following scores: self-esteem 3.40±0.53, appearance satisfaction 2.96±0.56, satisfaction with the major 3.80±0.61, and employment stress 2.23±0.75. Significant differences in employment stress according to general characteristics of subjects were observed in gender (t=7.40, p=.007), entering nursing college motivation (F=3.24, p=.023), and college life satisfaction (F=16.722, p<.001). Employment stress showed a negative correlation with self-esteem (r=-.433, p<.001), appearance satisfaction (r=-.307, p<.001), and satisfaction in major (r=-.534, p<.001). The satisfaction with the major (β=-.371, p<.001), self-esteem (β=-.166, p=.026), appearance satisfaction (β=-.132, p=.045), entering nursing college motivation (β=.163, p=.006), and gender (β=.131, p=.033) confirmed as a factors affecting the employment stress and accounted for 35.6% of the variance. Based on the results, it is necessary to develop employment-competency reinforcement programs to increase the level of satisfaction in the major, appearance satisfaction, and self-esteem to reduce the employment stress of nursing college students.

As a practical and effective seismic resisting technology, the base isolation system has seen extensive applications in buildings and bridges. However, a few problems associated with conventional lead-rubber bearings have been identified after historical strong earthquakes, e.g., excessive permanent deformations of bearings and potential unseating of bridge decks. Recently the applications of shape memory alloys (SMA) have received growing interest in the area of seismic response mitigation. As a result, a variety of SMA-based base isolators have been developed. These novel isolators often lead to minimal permanent deformations due to the self-centering feature of SMA materials. However, a rational design approach is still missing because of the fact that conventional design method cannot be directly applied to these novel devices. In light of this limitation, a displacement-based design approach for highway bridges with SMA isolators is proposed in this paper. Nonlinear response spectra, derived from typical hysteretic models for SMA, are employed in the design procedure. SMA isolators and bridge piers are designed according to the prescribed performance objectives. A prototype reinforced concrete (RC) highway bridge is designed using the proposed design approach. Nonlinear dynamic analyses for different seismic intensity levels are carried out using a computer program called "OpenSees". The efficacy of the displacement-based design approach is validated by numerical simulations. Results indicate that a properly designed RC highway bridge with novel SMA isolators may achieve minor damage and minimal residual deformations under frequent and rare earthquakes. Nonlinear static analysis is also carried out to investigate the failure mechanism and the self-centering ability of the designed highway bridge.

The development of technology has enabled users to customize avatars using various combinations and appearances in MMORPG. This study investigated the loyalty and user immersion factors of MMORPG avatar customization, which included personal factors (self-esteem, self-efficacy) and environmental factors (challenging spirit, sense of unity). immersion factors were extracted and a research model was established by observing precedent studies conducted on Flow theory and on the development and transformation of avatars. This study established a theory based on a developed research model and by surveying the users of AION, a MMORPG game, who actively enjoyed avatar customization, after determining measurement items based on precedent studies. The research results showed that self-esteem, a challenging spirit and sense of unity must be enhanced to increase the customization immersion. In addition, research results showed that the degree of loyalty increased with higher customization immersion.

The purpose of this study is to identify the factors that influence users' intention to use mobile services in academic libraries, based on the Davis' Technology Acceptance Model. This study employed both perceived usefulness and perceived ease of use, which were core variables in TAM, and added perceived playfulness that was recently applied to many researches on mobile system acceptance intention. As external variables, ubiquitous ability, context awareness, and mobile internet self-efficacy were employed. The data was collected from 325 surveys from two academic libraries and was analyzed with SPSS 18.0 and AMOS 21.0. As a result, perceived usefulness was the most significant factor in predicting users' acceptance intention and perceived ease of use was an indirect determinant of service usage. But perceived playfulness was not significantly correlated. Ubiquitous ability among external variables had a significant effect on perceived usefulness, context awareness did on both perceived playfulness and ease of use, and mobile internet self-efficacy did on perceived ease of use. Based on the findings, this study discussed theoretical and practical implications in academic library mobile service area.

This study investigates the innovation resistance when blockchain technology is introduced for the shipping and port industry. For the development of a research model with suitable measures, we review and focus on innovation resistance factors with the blockchain technology derived from previous studies. In this research, we consider four factors (innovation characteristics, consumer characteristics, environmental characteristics, and cost characteristics) with innovation resistance as dependent variables. The innovation characteristics include relative benefits, complexity, and perceived risk. The consumer characteristics consider attitude toward existing products, innovation, and self-efficacy. Social impact variables are environmental characteristics and rationality of cost. In the statistical analysis, we set up eight hypotheses to test the significances between variables and find the following four empirical results. First, the relative advantage and the perceived risk have a significant effect on innovation characteristic, but the complexity of this characteristic has no significant effect on innovation resistance. Second, the rationality of cost has no significant effect on innovation resistance. Third, the attitude toward existing products has a positive effect and the innovation of the consumer characteristic has a negative effect on innovation resistance, while the self-efficacy has no significant effect. Finally, the social impact has a significant effect on innovation resistance to blockchain in the shipping and port industry.
