Digitalization and digital transformations have metamorphized the face of Financial Inclusion globally, more so, in cash obsessed economies like India. The purpose of our study is to empirically analyze the users' intention to adopt digital payment systems, post Demonetisation, during the COVID-19 pandemic in India. The conceptual framework for the study is based on the Unified Theory of Acceptance and Use of Technology (UTAUT) adoption model with added operationalized constructs of Perceived Risk and Stickiness to use Cash. A total of 326 respondents were surveyed using a pre-tested questionnaire during the Nationwide Lockdown 3.0 in India. These responses were analyzed using Partial Least Squares - Structural Equation Modelling (PLS-SEM) technique. The findings of the study revealed that performance expectancy and facilitating conditions directly influence the intention of individuals to use digital payment systems, whereas the effect of perceived ease of use on digital payment systems is mediated through the attitude towards the digital payment systems during COVID-19 pandemic situation. Implications of the proposed adoption model are discussed. This will enable the other developing economies to formulate a digital ecosystem, that is here to stay even after the pandemic.

Purpose - The purpose of this study is to assess the perceived importance and satisfaction of domestic tourists who visited Venice, Italy, regarding the attributes of overtourism. Design/methodology/approach - An online survey was conducted to measure the tourist perceived attributes of overtourism from November 8th to 22nd, 2023. Convenience sampling was employed to target study participants who are domestic tourists in Venice, Italy. A total of 127 responses were used for analysis, including frequency analysis, paired-sample t-tests, and Importance-Performance Analysis (IPA). Findings - First, the results of the IPA showed that attributes related to urban facilities and spaces directly associated with travel behavior were highly rated in both importance and satisfaction by tourists. Second, attributes related to carrying capacity were perceived as highly important but had lower satisfaction level. Third, tourists evaluated the management of affordable prices for tourism products as both less important and less satisfying. Lastly, attributes related to the protection of local businesses showed higher satisfaction levels compared to their perceived importance. Research implications or Originality - This study contributes to an extended understanding of overtourism by examining the phenomenon from the tourists' perspective.

As cultured plant cells can grow in high oxidative stress conditions, they form an excellent system to study antioxidant mechanisms and the mass production of antioxidants. Oxidative stress is a major cause of damage in plants exposed to various types of environmental stress, including heavy metals, such as cadmium (Cd). Heavy metal accumulation can interfere with many cell functions and plant growth. To evaluate the contribution of oxidative stress to Cd-induced toxicity, cultured sweetpotato (Ipomoea batatas) cells were treated with increasing concentrations of Cd (0, 10, 25, and 50 μM) and cultured further. Cell growth was significantly inhibited by 25 and 50 μM of Cd, and the total protein content increased with 50 μM of Cd. Additionally, the activity of peroxidase (POD) and ascorbate peroxidase (APX), antioxidant enzymes that remove hydrogen peroxide (a reactive oxygen species), increased in the cells after treatment with 50 μM of Cd. The expression analysis of POD, APX, and peroxiredoxin (PRX) isolated from sweetpotato cultured cells in a previous study revealed the differential expression of POD in response to Cd. In this study, the expression levels of several acidic POD (swpa2, swpa3, and swpa4) and basal POD (swpb1, swpb2, and swpb3) genes were increased in Cd-treated cultured cells. These results indicate that Cd-mediated oxidative stress is closely linked to improved POD-mediated antioxidant defense capacity in sweetpotato suspension-cultured cells.

Robotics applications are greatly needed in hazardous locations, e.g., fusion and fission reactors, where robots must perform delicate and complex tasks under ionizing radiation conditions. The drawback is that some robotic parts, such as active electronics, are susceptible to radiation. It can lead to unexpected failures and early termination of the robotic operation. This paper analyses the ionizing radiation effect from 0.09 to 1.5 Gy/s in robotic components (microcontrollers, servo motors and temperature sensors). The first experiment compares the performance of various microcontroller types and their actuators and sensors, where different mitigation strategies are applied, such as using Radiation-Hardened (Rad-Hard) microcontrollers or shielding. The second and third experiments analyze the performance of a 3-Degrees of Freedom (DoF) robotic arm, evaluating its components' responses and trajectory. This study enhances our understanding and expands our knowledge regarding radiation's impact on robotic arms and components, which is useful for defining the best strategies for extending the robots' operational lifespan, especially when performing maintenance or inspection tasks in radiation environments.

Many South Korean universities highly value and place much investment on the development of students' characteristics as their core competency, offering corresponding educational initiatives and programs. The present study specifically evaluated the level of characteristic competency among freshmen at C University, in which characteristic development is at the central to the institution's core competency. The researchers conducted the study to utilize the findings to inform the design of liberal arts courses and extracurricular programs. The study recruited 210 freshmen at C University in Changwon, South Korea. To ensure anonymity of the respondents, an online questionnaire was administered during the data collection period (i.e., between December 5th and 7th, 2022) with a total of 201 faithful responses finally analyzed. The results showed an average characteristic competency level of 4.21 out of 5 among the freshman participants. Notably, the highest score was ranked in the 'righteous domain' (4.27±0.66), whereas the 'behavioral domain' scored the lowest (4.08±0.77). These findings provide valuable insights for the development of educational programs that aim to promote characteristic competency among university students. The implications of the findings are further discussed.
