Smartwatch, one of the popular forms of wearable gadget and a converging point of information technology innovation and fashion, is gaining much acceptance in countries belonging to the Asia-Pacific region. However, little is known about factors affecting consumers' intention to use smartwatches in Bangladesh. Therefore, this study explores factors driving Bangladeshi consumers' intention to use smartwatches and expands the general understanding of the emerging Asia-Pacific region's market. The study extends the conventional Technology Acceptance Model (TAM) by incorporating perceived enjoyment, aesthetic appeal, healthology, and two fashion-related factors, such as fashion innovativeness and fashion involvement. Data representing 300 respondents were analyzed using the structural equation model (SEM). The results reveal that, among other predictors, attitude toward using has the strongest direct effect on behavioral intention to use smartwatches. Moreover, attitude toward using smartwatches is significantly influenced by perceived enjoyment, perceived usefulness, perceived ease of use, fashion innovativeness, and fashion involvement. The study further discusses some interesting theoretical contributions that would be important insights for future studies. The empirical findings of this study would benefit the manufacturers and marketers who are trying to enter or penetrate the market in the Asia-pacific region.

The general aspects for the future warfare shows that the concept of firepower and maneuver centric warfare has been replacing with that of information and knowledge centric warfare. Thus, some developed countries are now trying to establish the information systems to perform intelligent warfare and innovate defense operations. The C4I(Command, Control, Communication, Computers and Intelligence for the Warrior) systems make it possible to do modern and systematic war operations. The basic idea of this study is to investigate how TAM(Technology Acceptance Model) can explain the acceptance behavior in military organizations. Because TAM is inadequate in explaining the acceptance processes forcomplex technologies and strict organizations, a revised research model based upon TAM was developed in order to assess the usage of the C4I system. The purpose of this study is to investigate factors affecting the usage of C4I in the Korean Army. The research model, based upon TAM, was extended through a belief construct such as self-efficacy as one of mediating variables. The self-efficacy has been used as a mediating variable for technology acceptance, and the variable was included in the research model. The external variables were selected on the basis of previous research. The external variables can be classified into following: 1) technological, 2) organizational, and 3) environmental factors on the basis of TOE(Technology-Organization-Environment) framework. The technological factor includes the information quality and the task-technology fitness. The organizational factor includes the influence of senior colleagues. The environmental factor includes the education/train data. The external variables are considered very important for explaining the behavior patterns of information technology or systems. A structured questionnaire was developed and administrated to those who were using the C4I system. Total 329 data were used for statistical data analyses. A confirmatory factor analysis and structured equation model were used as main statistical methods. Model fitness Indexes for measurement and structured models were verified before all 18 hypotheses were tested. This study shows that the perceived usefulness and the self-efficacy played their roles more than the perceived ease of use did in TAM. In military organizations, the perceived usefulness showed its mediating effects between external variables and dependent variable, but the perceived ease of use did not. These results imply that the perceived usefulness can explain the acceptance processes better than the perceived ease of use in the army. The self-efficacy was also used as one of the three mediating variables, and showed its mediating effects in explaining the acceptance processes. Such results also show that the self-efficacy can be selected as one possible belief construct in TAM. The perceived usefulness was influenced by such factors as senior colleagues, the information quality, and the task-technology fitness. The self-efficacy was affected by education/train and task-technology fitness. The actual usage of C4I was influenced not by the perceived ease of use but by the perceived usefulness and selfefficacy. This study suggests the followings: (1) An extended TAM can be applied to such strict organizations as the army; (2) Three mediation variables are included in the research model and tested at real situations; and (3) Several other implications are discussed.

This study was performed to figure out the effects of perceived usefulness and ease of use in Technology Acceptance Model(TAM) affecting acceptance attitude and intention to use in smart learning. In addition, the study recognized the need for differentiation of learning time by analyzing the difference of effects influencing acceptance attitude of perceived usefulness and ease of use during learning time, which is at the beginning, midterm, and at the end of the term. As the results of the study, it showed that there were differences between the factors, the learning time of which was considered, affecting acceptance attitude and intention to use. Furthermore, in order to improve the effectiveness of building a smart campus, which is currently under the construction, the study argued that universities need to consider the learning relevance and subjective norm as important factors in perceived usefulness of smart learning. Finally, the need for the design of various smart learning types became accepted considering learning time.

Patients with advanced cancer cope with various issues, especially psychological symptoms, such as anxiety about death. Previous research from various countries indicates that most advanced cancer patients perceive distress before death, which means they cannot accept death peacefully. The purpose of this study was to examine the factors associated with death acceptance of Thai patients with advanced cancer. The participants were 242 adult patients with advanced cancer from three tertiary hospitals in Bangkok, Thailand. The research instruments consisted of 7 questionnaires: a personal information questionnaire, the death anxiety questionnaire, Buddhist beliefs about death questionnaire, the unfinished task questionnaire, general self-efficacy scale, family relationship questionnaire, and death acceptance scale. These instruments were tested for their content validity by a panel of experts. All instruments except the first one were tested for reliability, and their Cronbach's alpha coefficient were .86, .72, .74, .74, .89, and .70, respectively. Descriptive statistics, Pearson's correlation, Point-biserial correlation coefficient, and stepwise multiple regression were used to analyze the data. The results revealed that a total of 42% of variance of death acceptance among Thai patients with advanced cancer was explained by death anxiety, Buddhist beliefs about death, and self-efficacy. Knowing these factors provides further information for nurses to help patients to cope with their death. From this crucial knowledge, nurses can develop interventions in decreasing or controlling anxiety about death, promoting Buddhist beliefs about death, and enhancing self-efficacy of advanced cancer patients. Therefore, a better quality of life and good death can be achieved.

This study was done to determine the factors influencing smoking-cessation behavior in female university students. A total of 534 students participated in this cross sectional study by answering a questionnaire. The data collection was done between September 1 and October 31, 1997 The measurement tools used in this study were the self help change process scale (Cronbach's alpha＝.9930 : developed by Oh & Kim, 1996) for smoking-cessation behaviors, the self efficacy scale(Cronbach's alpha＝.8250 : developed by Sherer et al, 1982), the sex role acceptance scale (KR－20＝.7757 : developed by Kim, 1991) and the social support scale(Cronbach's alpha＝.9172 : developed by Park, 1985). The summarized results are follows : 1. The mean scores for smoking-cessation behaviors in smokers (N＝150) was 91.72 that was considered a middle score compared to the total possible score of measurement tool (150.0). The mean score for smoking-cessation behaviors by smoking-cessation step showed significant different between the groups(F＝11.71, p＝.000). 2. The group with no experience in smoking(N＝332) showed a high general self efficacy score (t＝5.24, p＝.000), and more openness to sex role acceptance(t＝-2.15, p＝.032) compared to the group with smoking experience (N＝202). 3. General self efficacy, sex role acceptance, and social support were not different significantly between the groups according to the steps in smoking-cessation. 4. Significant factors influencing smoking-cessation behavior (total, sub concepts) were religion, sex role acceptance, social support, smoking duration, smoking attitude, time of smoking onset, amount of smoking, drinking, and perception of health status. 5. Smoking-cessation behaviors which explained 11% of the variance were smoking attitude, and smoking duration. In conclusion, this study identified factors influencing smoking-cessation behavior. Thereby it will help in the development of smoking-cessation intervention strategies. For future research, exploration other determinants of smoking cessation behaviors, evaluation of intervention efficiency, and comparative study by gender characteristics are needed.
