Aircraft ground services are essential to the aviation industry and aviation services, yet management systems and improvement measures for operations and safety have not been adequately addressed in the revision of the old aviation law. This study utilized structural equation modeling and the UTAUT model to analyze the perceived acceptance of smart safety technologies among ground handling service workers. The findings indicated that perceived ease of use had a more significant than perceived usefulness impact on the acceptance of smart safety technologies among ground handling service workers. In light of these findings, it is recommended that the aviation safety management authority establish a policy vision for the adoption of smart safety technologies and consider implementing measures such as the introduction of smart safety technology test beds to enhance safety management and work efficiency of aircraft ground handling services.

Radio Frequency Identification (RFID) is one of Identification Technologies today. Many of the large retailers in the United States and Europe have established requirements for their suppliers to use RFID technology in 2004. Recently Airbus and Boeing have announced plans to develop a single RFID specification to be used by both companies to use RFID tags to identify commercial aircraft parts. However, it does not mean the end of barcode and it may take several years before the wide adoption of the RFID. This is because a precise business process reengineering is required with technology itself to get the potential benefits of RFID. In this paper, we introduce an RFID enabled air baggage handling process which has been developed and tested recently. We believe our study would give a good guideline for further researches on RFID application in the aviation industry.

TVarious studies in different industries have proven the effectiveness of nanotechnology, which is considered as a representative technology that makes lives faster and more convenient and economical. However, as nanomaterials are tiny, consumers are concerned on whether they can do any physical harm. Therefore, based on the perceived usefulness and ease of use from the generally used Technology Acceptance Model (TAM), this study added additional variables including perceived risk. Moreover, this study introduced three kinds of trust (institution, people, and technology trust) as moderating variables, which can reduce the negative effect of perceived risk. Based on the analysis using the Structural Equation Model, we determined that perceived usefulness and ease of use positively influenced the intention to adopt nanotechnology products. Thus, when consumers regarded nanotechnology products as efficient and convenient, they showed increased intention to adopt the technology. Furthermore, perceived risk negatively affected the intention to adopt nanotechnology products, that is, when customers' perceived risk increased, the adoption intention of nanotechnology product decreases because of the potential risk from nanotechnology. On the one hand, the negative effect of perceived risk on adoption intention decreased when trust in nanotechnology washigh and when consumers highlytrust experts or administrators. On the other hand, trust in government, public institutions, and companies which produce nanotechnology products showed no significant moderating effect. This study is meaningful as it generalized TAM by applying the model to new nanotechnology products and extended existing studies by the addition of perceived risk and various trust factors to the model.

There are several problems facing our society today that are caused by demographic changes, such as an increase in the ageing population. The rapid increase in the aging population leads to increases in medical costs and a higher demand for care services for the elderly. The needs and burdens associated with elderly care are growing, but the human resources and costs to meet these needs are limited. Welfare technology has been suggested as an effective way to solve the discrepancy between higher welfare needs and limited resources. This study aims to explore the current trends and challenges of using welfare technology related to elderly care through literature review. Practical ways to expand uses of welfare technology are also provided. In order to make effective and practical use of welfare technology, public awareness and education, the cooperation of related organizations, the expansion and utilization of Living Labs, and the development and adoption of welfare technology are required.

Clearly, the smartphone is increasingly playing a greater role in everyday life, thus providing opportunities to evaluate how well the use of the smartphone meets the requirements of undergraduate students in independent learning outside of a classroom setting. This study used the task-technology fit (TTF) model to explore the effectiveness of smartphone usage to interact with learning materials in independent learning outside of classrooms, the need for smartphone support, and the fit of devices to tasks as well as performance. First, the study used interviews, observation, and survey data to identify what are the most important constructs of smartphones that stimulate students to interact with learning materials in independent learning outside of classrooms. Based on the findings from the exploratory study and Task Technology Fit theory, we postulated the Navigation design, Ergonomic design, Content support, and Capacity as the essential dimension of the smartphone construct. Then, we proposed a research model and empirically tested hypotheses with the structural model analysis. The results reveal a significant positive impact of task and technology on TTF for smartphone usage to interact with learning materials in independent learning outside of classrooms; it also confirmed the TTF and performance have a direct effect on actual use.

Purpose - This study aims to provide a brief understanding of usability and its extended models with TAM as well as identifying additional determinants that had been suggested in previous studies on mobile services. Research design, data, and methodology - Empirical data were collected by conducting a field survey of potential mobile application service users. The call for participation was also made in mobile related application issues, which were widely discussed. Result - The ease of use and usefulness had a significantly positive influence on attitude and intention. It also was revealed that added value services can offer practical value to customers. Thus, positive attitudes toward the adoption of services by customers are present when they perceive higher usefulness and ease of use of mobile application services. Conclusion - It was indicated that customers who are more inclined to try new products or who have a higher demand for new things tend to think about those functionalities and added value mobile application services from the perspective of usefulness and ease of use and operation.

This study proposed a novel model to investigate influential factors affecting the intention to continue using increasingly popular food delivery apps (FDAs). The proposed theoretical model is developed and validated to extend traditional technology acceptance and adoption theories by identifying several determinant factors that capture the unique context of FDAs continuous usage. Hypotheses were tested using a partial least square structural equation modeling approach (PLS-SEM) on data collected from 331 actual FDAs users during the COVID-19 pandemic. The results reveal that convenience, perceived compatibility, delivery experience, and online reviews significantly influence the continuous usage of FDAs. The findings also confirm the importance of continuous intention on the actual use of FDAs. The research model of this study explains 65% of variance in continuous intention and 47% in actual use. The insights provided by this study suggest fruitful directions for future research. They can also help FDAs companies, developers and marketers with strategies and tips for further development and growth by ensuring users' continuous usage of these platforms.

Interest in the use of smart packaging systems for food products has increased in recent years. Therefore, food researchers are focusing on the development of new indicator based smart packaging technologies by using anthocyanin-based natural dye. Anthocyanins are one of the plant constituents known as flavonoids and responsible for the bright and attractive orange, red, purple, and blue colors of most fruits, vegetables, flowers, and some cereal grains. Indicators of natural dyes such as anthocyanins could express the quality and shelf life of perishable food products. However, the sensitivity and stability for their use in smart food packaging should be established to reach the market proposals. This review article focuses on recent studies related to use of natural dyes based on anthocyanin for smart food packaging applications. This study offers valuable insight that may be useful for identifying trends in the commercialization of natural dyes or for identifying new research areas. This review also provides food and packaging scientists with a thorough understanding of the benefits of anthocyanin-based natural dyes for shelf life indicator when applied to package material specific foods and hence can assist in accelerating commercial adoption.

RFID(Radio Frequency Identification) technologies enjoy an enormous interest in all throughout the world, not only from the research but also from corporate practice. Although bar code is gradually substituted with RFID technology, the use of RFID technology in the companies is at the early stages and it's potential value isn't fully realized yet. RFID-related-trust is needed to solve these problems because these phenomena are related to uncertainties or risks disturbing RFID diffusion. This paper focuses on trust in the adoption of RFID and analyzes the effect to RFID technology acceptance of trust. This paper proposes 5 second constructs of trust; institutional trust, trust between companies, trust within company, technology trust, and service provider trust. In order to analyze some relationships between trust variable and 4 variables in TAM, structural equation modeling(SEM) is developed and SPSS 12.0 and AMOS 7.0 are used for analyses.
