Smartwatches are wrist-mounted, therefore hold strong advantages because of their connection to the wrist and mount location. These characteristics have given smartwatches great opportunities in today’s health care and other applications market. The purpose of this study is to inspect the mediating effects of perceived ease of use, and perceived usefulness between important antecedent variables, and continuous intention to use smartwatch Electrocardiography (ECG) and Photoplethysmography (PPG) applications. The framework was extended by including Safety, Convenience, Affective Trust, and Cognitive trust. For this research, 340 samples were collected from Amazon Mechanical Turk, via an online survey and 331 respondents were found valid. The structural equation modeling technique was used since it allows simultaneous analysis. The results suggest that User Safety should be considered beyond experiential value and intention. This work robustly explores the continuous intention to use smartwatch ECG and PPG applications. But the primary purpose is to explore the affiliation among antecedents (i.e., Safety, Convenience, Affective Trust, Cognitive trust, perceived ease of use, perceived usefulness and continues intention to use). The results of the analyses show that Safety, Convenience, and Cognitive trust have positive impacts on perceived usefulness. Safety, Convenience, and Cognitive trust have positive impacts on perceived ease of use. A satisfactory overall model fit index supports most of the proposed hypotheses. The empirical findings of this research is intended to provide a new understanding and explain the fundamental mechanism under users’ decision-making process to trust and intention to use smartwatch ECG and PPG application.

Consumption of luxury on a lavish scale in order to increase one's prestige is referred to as conspicuous consumption. Conspicuous consumption is the act of buying products or services in order to showcase one's fortune and demonstrate one's social status, especially when products or services are displayed in public and are out of reach for other members of one's class. This study was conducted to examine the effects of Materialism and Conspicuous Consumption between some important antecedent variables and continuous intention. This framework was extended by including Self-Esteem, Public Self-Consciousness, Being Fashionable, and the Need for Uniqueness. The methodologies adopted for this study are conceptually and practically linked with previous studies, to grow on them while minimizing the limitations. The first phase was identifying the research objectives, scope, and research questions, as well as examining the literature, and creating and refining the research model. On the other hand, Materialism and Conspicuous Consumption to continuous intention are the focus of the second phase which was derived from the literature review and was empirically confirmed using data from an online survey. The third phase is analyzing the data and generating results. For this research, 276 samples were collected via an online survey and 270 respondents were found valid. The structural equation modeling technique was used since it allows simultaneous analysis. The model was examined using the data acquired for the research. This study used SmartPLS 3 and IBM SPSS version 20. This work robustly explores Materialism and Conspicuous Consumption. But the primary purpose is to explore the affiliation among antecedents (i.e., Self-Esteem, Public Self-Consciousness, Being Fashionable, Need for Uniqueness, Materialism, Conspicuous Consumption, and Continuous Intention). The results of the analyses show that Self-Esteem, Public Self-Consciousness, Being Fashionable, and the Need for Uniqueness have positive impacts on Conspicuous Consumption. Being Fashionable and the Need for Uniqueness have positive impacts on Materialism. A satisfactory overall model fit index supports most of the proposed hypotheses. The empirical findings of this research work provide a new understanding and explain the fundamental mechanism under users' decision-making process to Continuous intention.

Continuous glucose monitoring (CGM) devices are medical devices that continuously measure and display blood sugar levels in real time. A small sensor that is implanted just beneath the skin, a transmitter that transmits data from the sensor to a display device, and a display that shows the blood sugar levels in real-time are the typical components of these devices, the user might be warned via alarms on some CGM devices if their blood sugar levels are too high or too low [1]. Examining the fundamental mediating effects of the hedonic value, health interest, and utilitarian values between significant antecedents and continuous intention to use CGM devices is the general goal of this study. By integrating several significant antecedents to the hedonic and utilitarian values research framework, the study expanded the hedonic and utilitarian behavioral decision research model by adding health interest variable. The key antecedents included are Safety, interactivity, Result Accuracy, User interface, Self Efficacy, and Personal Innovativeness. The study also intends to improve user's comprehension of CGM device adoption and continue intention to use, the methodology used in the study is suitable for using an online survey to collect data and answer the research questions, the methodologies are also conceptually and practically linked with previous research, the focus of this research is on CGM devices systems having qualities that enable users to foel upbeat while using them and to have a good attitude toward using them in the future. This study were to use a complete approach to examine the data in a quantitative analysis, an expanded hedonic and utilitarian behavioral decision research framework for the adoption and continues intention to use CGM device. 109 samples were gathered from an online survey and 100 valid responses were analyzed after eliminating 9 invalid responses, the structural equation modeling technique was adopted for this study, it enables simultaneous analysis. SmartPLS 4.0 and IBM SPSS version 23 were used for the analysis. The results of the analyses show that Safety, Interactivity, Self-efficacy, Result Accuracy, User Interface, and Personal Innovativeness have positive impacts on hedonic value, health value, and utilitarian value to adoption and continuous using CGM devices.
