With the advancement of technology, people constantly use IT through the Internet. In this modern living environment, many individuals exploit this technological landscape for illegal gains and criminal activities. Judicial investigation units gather relevant evidence from the crime scene and process it when a crime occurs. When the medium used in criminal activity involves information technology, it is referred to as digital evidence. Unlike traditional evidence, which leaves traces if moved or altered, digital evidence can be copied without any detectable changes, posing challenges to maintaining its integrity and accuracy. This article explores how digital identification can ensure that the content of a report matches the evidence seized at the scene. It also addresses how the validity of digital evidence, as presented by the investigating authority, can be upheld in court. Additionally, it discusses the use of digital evidence and electronic handwritten signatures to enhance evidence preservation measures. © 2024 IEEE.

Today's pluralistic and globalized society requires a global perspective in how we think, view ourselves, and relate to others to collaborate successfully with people with different cultural backgrounds. To support the development of a global perspective, universities cultivate international co-operations to enable international mobility for students, faculty, and staff. However, in-person mobility can be inhibited due to various reasons. To support a wider pool of students gaining international experience, modern digital mediated course formats can be used to offer virtual instead of in-person mobility. This contribution evaluates a digital mediated course for mechanical engineering students (Global Engineering, GE) held in co-operation between an US and a Portuguese university, where internationally mixed student groups working on design projects in an Hyflex setting. Asides a literature driven discussion about the need for Global Engineers and a detailed description of the GE course, a longitudinal analysis was performed to assess the impact of the GE course on the students' development of a global perspective. The longitudinal analysis showed strong statistical support that the digitally mediated GE course improved the participating students' global perspective, assessed with the Global Perspective Inventory (GPI), tremendously. The observed improvements were in three of the six GPI dimensions comparable to an in-person semester abroad. Limitations of the study and future investigations are discussed. © 2023 IEEE.

Banking and Fintech are encouraged to collaborate to fill each other's deficiencies and further grow the digital economy. This collaboration will create benefits for both banks, Fintech, and customers. However, this collaboration also comes with risks. The Financial Services Authority has stated that several risk phenomena can occur in the collaboration of banks and Fintech. First, no law guarantees the protection and exchange of customer personal data. Second, the risk of customer data leakage. Third, the risk of cyberattacks. The fourth is the risk of outsourcing. This research aims to analyze the risk phenomenon of bank and fintech collaboration through the Enterprise Risk management Framework approach. This study uses a phenomenological research approach, which is a study to study how individuals subjectively experience and give meaning to the phenomenon. Data analysis based on this phenomenon data uses qualitative methods involving banking and fintech practitioners. The results of this study describe the phenomenon of risks that occur in banking-fintech collaboration, as approached by the Enterprise Risk management framework. Proper risk management will minimize risks when the Bank collaborates with FinTech. This study hopefully contributes to making brief policy recommendations on bank and fintech collaboration risk management for Indonesian financial regulators.

In this paper, the authors investigate the current state of the lighting design and control sector in Thailand’s creative industry. The government aims to promote the creative industry as a key source of income, but there needs more skilled professionals in the industry. The authors have found that successful cases have used the Internet for remote controlling in the creative industry in other countries. Therefore, the paper will explore the potential of using technology to improve professional efficiency and assess the feasibility of implementing remote lighting control systems via the Internet with Thai lighting designers and lighting console operators. Data will be collected through qualitative in-depth interviews and quantitative surveys. The results have shown a promising acceptance rate of wireless devices for lighting control due to their mobility, flexibility, cost-effectiveness, and positive attitudes toward adopting Internet technology. The authors have also proposed a concept design for an internet-based control system tailored to Thai users, focusing on simplicity, ease of connection, and user-friendliness to accommodate those with limited network configuration knowledge. The proposed system aims to reduce professionals, save time, and increase convenience, leveraging Thailand’s extensive wireless internet coverage. These systems could significantly benefit Thailand’s creative industry by addressing the shortage of skilled professionals and improving efficiency.

Statistical trends of rainfall (annual and seasonal rainfalls) in Kerala, India were characterised using the 44-years (1980–2023) data of Modern-Era Retrospective Analysis for Research and Applications (MERRA) version 2. Monthly rainfall data were collected from the selected fifty locations which represent the state as a whole, and the collected data were then categorised into annual as well as seasonal (winter, summer, monsoon and post-monsoon) datasets based on the classification proposed by Indian Meteorological Organisation (IMD). Lag-1 autocorrelation, modified Mann Kendall (mMK), Pettitt test and Theil-Sen’s slope methods were used to determine the statistical characteristics of rainfalls in Kerala. Mean rainfalls were 3124 mm, 66 mm, 527 mm, 1667 mm and 862 mm, respectively, for annual, winter, summer, monsoon and post-monsoon periods. mMK based statistical trend analysis revealed an overall decreasing trend characteristics in annual (-0.54 mm.y⁻¹), monsoon (-1.20 mm.y⁻¹), and post-monsoon (-0.93 mm.y⁻¹) seasons whereas winter and summer rainfalls showed an increasing trend (0.67 mm.y⁻¹ and 3.40 mm.y⁻¹, respectively) for the state as a single unit. Pettitt test indicated four dominant periods of change in rainfall characteristics in the study area that spanned over the decades of 1980, 1990, 2000 and 2010, in which major changes in annual and seasonal rainfalls were occurred during 1990’s, 2000’s and 2010’s. Theil-Sen’s slope-based estimation of rate of change in rainfall showed an average variation of -4.33 mm.y⁻¹, 0.17 mm.y⁻¹, 6.27 mm.y⁻¹, -6.54 mm.y⁻¹ and − 3.28 mm.y⁻¹ for annual, winter, summer, monsoon and post-monsoon seasons, respectively. Though the winter and summer rainfalls showed an increase in its rate during the period of analysis, annual rainfall showed an overall reduction in the amount of rainfall received in the state.

This study aimed to optimize the ultrasound-assisted extraction of phenolic compounds from the bagasse of umbu-cajá (Spondias bahiensis), a native Brazilian fruit, and to assess their bioaccessibility. Additionally, the influence of different concentrations of the umbu-cajá bagasse (SBB) extract on the oxidative stability of pre-cooked goat meatballs was investigated over a 10-day refrigerated storage period by quantifying lipid oxidation products. A central composite rotational design determined the optimal ethanol concentration, sonication time, and bagasse-solvent ratio. The optimized extract was applied to meatballs at two concentrations: EX2 (meatballs with 7.0 g/100 g of added SBB extract) and EX4 (meatballs with 13.7 g/100 g of added SBB extract). A control treatment (no antioxidant) and BHT-treated meatballs (0.02 g/100 g) were included as references. Meatballs were evaluated by measuring instrumental color, peroxide value, TBARS, carbonyl compounds, and through simulated digestion. Optimal extraction conditions were 55 % ethanol, 20 min of sonication, and a 1:36.8 bagasse-to-solvent ratio (m/v). The extract showed high antioxidant activity and bioaccessibility of catechin (1243.75 %), epicatechin gallate (918.75 %), procyanidins B2 (915.38 %), gallic acid (319.76 %) and procyanidins B1 (136.36 %). SBB extract slowed lipid oxidation until day 10 and protein oxidation until day 5 but did not inhibit color change. The meatballs had low content of oxidative compounds and high antioxidant capacity in the intestinal fraction, indicating that SBB extract can partially or totally replace the synthetic preservative. © 2025

This paper analyses how collaborative practices influence sustainability initiatives and the relational rents of Brazilian coffee companies supplying global supply chains (GSC)s. Multi-case study data was collected via interviews and documentary analysis and examined using the relational view theoretical lens. The results indicate that collaborative practices lead to significant improvements within the supplier’s sustainability initiatives and consequently within their processes related to the exportation of goods. Thus this study suggests that collaborative practices generate important relational rents in GSCs (for example through relationship-specific assets) and are important facilitators of sustainability for emerging economy suppliers. © 2021 Taylor & Francis Group, LLC.

Graph Neural Networks (GNNs) frequently face class imbalance issues, especially in heterogeneous graphs. Existing GNNs often assume balanced class sizes, which isn’t true in many cases. Applying them directly to imbalanced data can lead to sub-optimal performance. Traditional oversampling methods, while effective, risk overfitting and face difficulties in reintegrating synthetic samples into the original graph. In this study, we introduce Framework of Imbalanced Node Classification on heterogeneous graph neural network with GAN (FincGAN), a new framework that utilizes oversampling techniques to address class imbalance in heterogeneous graphs. Instead of duplicating existing samples, FincGAN employs a Generative Adversarial Network (GAN) to create synthetic samples and uses deep learning-based edge generators to connect them back to the original graph. Our evaluations on spam user detection in the Amazon and Yelp Review datasets show that FincGAN outperforms baseline models in all essential metrics, including F-score and AUC-PRC score, showing its effectiveness in addressing class imbalance.

The studies carried out in the area of cell preservation have been of significant importance in recent years. This process, known as cryopreservation, has been used for decades and aims to preserve various cellular materials at cryogenic temperatures. Different methods allow cryopreservation, where the best known are the slow freezing and vitrification processes. Regardless of the process, it is necessary to use cryoprotective agents (CPAs) in conjunction with the cells to avoid possible cell damage during cryopreservation. Regarding the methods, they differ in their cooling rates and the concentration of CPAs used. According to some studies, the method that has been most studied is that of vitrification, which seeks to increase the cooling rate, reaching values above 20,000 ∘ C/min. Evaporation by a thin film of liquid nitrogen is one of the methods of vitrification, which uses a microstructure with a finned or porous surface for evaporation, and in these conditions cooling rates of up to 150,000 ∘ C/min were found, which shows a significant advance and alternative for cell cryopreservation. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
