This study develops a mediating model to explore the relationships between organizational characteristics, manager's knowledge, management commitment, user involvement, information quality, and management information system effectiveness in small- and medium-sized enterprises in Vietnam. Adapting scales from previous research, the authors designed questionnaires, which they distributed to respondents in Vietnamese small- and medium-sized enterprises. Also, by employing a meta-analytic path analysis throughout structural equation modelling (SEM) with sample of 356 respondents, authors indicate that organizational characteristics are directly related to management information systems effectiveness. Moreover, manager's knowledge, user involvement, and information quality show their important roles in the increase of management information system effectiveness, yet management commitment does not indicate a similar role in the growth of management information system effectiveness. Bootstrapping is utilized to discover the meditating role of information quality, illustrating that quality information mediates the linkages between user involvement, organizational characteristics, and management information systems. However, the mediating role of information quality in the relationship between management commitment, manager's knowledge, and management information systems is not significant. This study contributes to the management information system literature as well as to enhance MIS effects in small and medium-sized enterprises.

TQM is considered as a kind management innovation tools. Managers are apt to be embarrassed in face of too many emerging and diminishing faddish management innovation tools. In spite of their expected usefulness, the result of implementation used to be depressing. One of the most important things for successful implementation is to understand their correct usefulness and characteristics. This paper analyzes the characteristics of TQM as innovation tool by comparing TQM with other management innovation tools in terms of criteria derived in view of competitive strategy formulation.

Purpose: This study examines the relationship between content characteristics and customer viewing and purchase intention in live-streaming commerce. Research design, data, and methodology: For this purpose, seven independent factors such as entertainment, artistry, storytelling, informativity, interactivity, reliability, and technicality are extracted based on previous literature. The viewing intention and purchase intention are adopted as dependent factors. The role of 'immersion' is investigated as a mediating factor between the independent and dependent factors. Results: The results showed that entertainment, artistry, technicality, and reliability significantly affected immersion, and immersion affected viewing intention and purchase intention. Immersion was found to play a mediating role between content characteristics and consumer viewing and purchase intention. Conclusions: The results indicate that the content characteristics not only attract customers but also affect their immersion, viewing intention, and purchase intention directly or indirectly in the live-streaming commerce sector.

When designing the parameter on the multiple quality characteristics, there has been a study for optimization of problems, but there has been few former study on the possible conflicting phenomena in consideration of the correlations among the characteristics. To solve the issue on the optimal design for multiple quality characteristics, this study modelled the expected loss function with cross-product terms among the characteristics and derived range of the coefficients of the terms. The model will be used to determine the global optimal design parameters where there exists the conflict among the characteristics, which shows difference in optimal design parameters for the individual characteristics.

We purpose a decision model to select the optimal facilities for the Decision Making problems with multiple characteristics(nominal-is-best characteristics, larger-is -better characteristics, smaller- is -better characteristics). Using this model, concept of the loss function is used in this comprehensive method of for select the optimal preferred facilities. To solve the issue on the optimal preferred facilities for multiple characteristics, this study propose the loss function with cross-product terms among the characteristics and derived range of the coefficients of the terms.

This study analyzed the factors affecting the effectiveness of the Chemical Hazard Risk Management (CHARM). A survey was conducted on 104 learners who participated in the Risk Assessment training course at Occupational Safety and Health Training Institute. Through a self-administered questionnaire, the effect of personal characteristics, corporate characteristics, and safety and health level of the company on the effectiveness of chemical risk assessment was investigated. As a result of statistical analysis, the safety and health level of the company had a positive (+) effect on the effectiveness of Chemical Hazard Risk Management(CHARM), but personal characteristics and corporate characteristics had no relation to it. This study can be used as basic data for further research related to chemical risk assessment in workplaces.

The main objective of this paper is analyzing the effects of task uncertainty on EUC characteristics and end user satisfaction. Task uncertainty were identified as an important determinant of EUC characteristics. And the moderating effect of task uncertainty on the relationship between EUC characteristics and end user satisfaction was suggested. A field study was undertaken to test the hypothesized relationships among task uncertainty, EUC characteristics, and end user satisfaction Data were collected from 138 end-user of 19 Korean business organizations. The empirical results indicated that task uncertainty was significantly related to EUC characteristics and that task uncertainty had significant effect on the relationship between EUC characteristics and end user satisfaction. Implications and future research directions are drawn for the management of EUC and for further research on EUC.

This study was undertaken to explore the relationships between the personality characteristics (the rigidity and the acceptance of self and others) and the clothing behaviors according to the age and the occupation. The results were as follows; 1. In the clothing behavior, the subjects scored highest in aesthetics followed by comfort, modesty, management, dependence, interest, attention and approval in a descending order. 2. There was no significant relationship between the acceptance and the rigidity characteristics. 3. There was a highly significant relationship between the personality characteristics and the clothing behaviors. 4. There were significant differences in the rigidity characteristics and in modesty, comfort, management clothing variables according to the age. 5. There were significant differences in self-acceptance, rigidity characteristics and in management clothing variable according to the occupational status. 6. No significant interactions was found between age and occupation on personality characteristics and clothing behaviors.

A dual-mode power management for a hybrid-electric UAV with a cruise power of 200W is proposed and empirically verified. The subject vehicle is a low-speed long-endurance UAV powered by a solar cell, a fuel cell, and a battery pack, which operate in the same voltage bounds. These power sources of different operational characteristics can be managed in two different methods: passive management and active management. This study proposes a new power management system named PMS2, which employs a bypass circuit to control the individual power sources. The PMS2 normally operates in active mode, and the bypass circuit converts the system into passive mode when necessary. The output characteristics of the hybrid system with the PMS2 are investigated under simulated failures in the power sources and the conversion of the power management methods. The investigation also provides quantitative comparisons of efficiencies of the system under the two distinct power management modes. In the case of the solar cell, the efficiency difference between the active and the passive management is shown to be 0.34% when the SOC of the battery is between 25-65%. However, if the SOC is out of this given range, i.e. when the SOC is at 90%, using active management displays an improved efficiency of 6.9%. In the case of the fuel cell, the efficiency of 55% is shown for both active and passive managements, indicating negligible differences.
