Abstract: Blockchain is a new emerging technology that is mainly used to add security layers to many applications. Studies showed that businesses and manufacturing industries suffer from cyber-attacks, especially after the emergence of Industry 4.0 and IoT devices connected to the cloud for data sharing purposes, these interactions between IoT devices and the information involved in the transactions between companies and customers produce a massive amount of data daily. This phenomenon becomes an easy target for attackers due to the security limitations, data corruption and compromised reliability of the traditional manufacturing systems during data transferring. Many have focused on the methods to address these security limitations of the manufacturing businesses. This paper shed the light on the major smart manufacturing sectors that can potentially benefit from blockchain technologies, including cloud manufacturing, collaborative manufacturing, digital twin manufacturing, robonomics based smart manufacturing and the supply chain industry. The blockchain can enhance the security by creating a decentralized environment for the data to be stored, which will make the data stored immutable for improved security. These immutable data are nearly impossible to manipulate, replace, or falsify the data stored on the blockchain secured network.

Abstract: Cryptocurrency price prediction is a challenging task due to the inherent volatility and complexity of the market. In this research, we propose a hybrid Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) neural network model for predicting Bitcoin prices. The model is implemented using the TensorFlow and Keras libraries and is evaluated on historical Bitcoin price data obtained from Yahoo Finance. Our approach aims to leverage the strengths of both LSTM and GRU architectures to enhance the accuracy of price predictions. The results suggest that the proposed hybrid LSTM-GRU model holds promise for effectively capturing the complex dynamics of cryptocurrency markets, addressing the challenges associated with traditional time-series analysis techniques.

Abstract: Gesture-based systems have emerged as a prominent breakthrough in the field of smart access control, effectively integrating security measures with user comfort. This study presents a novel gesture detection framework for smart entry systems that combines the computational capabilities of a Random Forest Classifier with the practicality of Arduino-based hardware. Central to methodology is the utilization of MediaPipe, an advanced computer vision library, to extract hand motion landmarks from live video streams. The selected landmarks function as a comprehensive dataset for training a Random Forest Classifier, which has been specifically chosen due to its high level of accuracy and efficiency in managing intricate classification jobs. The model exhibits outstanding competence in the categorization of gestures in real-time, attaining high levels of accuracy that are crucial for ensuring dependable entrance control. The Arduino microcontroller plays a vital role in the execution of the entry mechanism as it serves as the intermediary between the gesture detection software and the tangible entry control hardware. The incorporation of gesture recognition technology facilitates a cohesive and prompt user experience, wherein identified motions are directly converted into input commands. The system's practical use is demonstrated through a series of detailed tests, which highlight its dependability and efficiency across diverse climatic circumstances. The findings underscore the system's capacity as a flexible and safe solution for contactless access in many environments, including both private homes and highly protected establishments. Furthermore, the study makes a substantial contribution to the larger domain of human-computer interaction by showcasing the practicality of advanced gesture detection systems in many everyday contexts. The suggested framework presents a novel approach to smart entry systems and also paves the way for further investigation in the domains of smart home automation and interactive systems. In these areas, gesture-based interfaces have the potential to deliver user experiences that are both intuitive and efficient.

Abstract: Objectives This research was to investigated the implicit knowledge of creative teachers possessed by middle school teachers in Korea and China. the study aimed to analyzed the cross-country variances and contribute to comprehension of the educational systems and cultural characteristics of both nations.&#x0D; Methods A survey was administered to a total of 174 middle school teachers in Korea and 187 middle school teachers in China. Participants were requested to freely crticulate the characteristics of creative teachers. The col-lected responses were subsequently analyzed from both cognitive and affective perspectives.&#x0D; Results The results revealed that Korean teachers ranked fluency, communication skills, originality, expertise, flexibility, respect, openness, consideration, breaking stereotypes, and encouragement as the foremost charac-teristics of creative teachers, in that order. Conversely, Chinese teachers mentioned originality, communication skills, expertise, applicability, flexibility, progressiveness, passion for education, fluency, respect, and humor as the key traits. While certain cognitive characteristics of creative teachers displayed similarities across both coun-tries, disparities were observed in their affective characteristics. Additionally, both countries placed greater em-phasis on the cognitive aspect of identifying a creative teacher, rather than the affective aspect. Chinese teachers exhibited a higher emphasis on the cognitive aspect than their Korean counterparts.&#x0D; Conclusions This study has effectively demonstrated dissimilarties in implicit perceptions regarding creative teachers between Korean and Chinese educators. The findings of this research are anticipates to enhance the un-derstanding of the educational systems and cultural characteristics prevalent in both countries.

Abstract: Because credit cards are utilized so frequently, fraud appears to be a significant concern in the credit card industry. It is challenging to quantify the effects of misrepresentation. Globally, credit card fraud has cost institutions and consumers billions of dollars. Despite the existence of numerous anti-fraud mechanisms, fraudsters continue to seek out novel methods and strategies to commit fraud. An additional challenge in the estimation of credit card fraud loss is that the magnitude of unreported or undetected forgeries cannot be determined, only losses associated with those frauds that have been detected can be measured. Implementing effective fraud detection algorithms through the utilization of machine-learning techniques is crucial in order to mitigate these losses and provide support to fraud investigators. This paper presents a machine learning-based method for the detection of credit card fraud. Three methodologies are implemented on the raw and pre-processed data. Python is used to implement the work. By comparing the accuracy-based performance evaluations of k-nearest neighbor and logistic regression with Random Forest, it is determined that the former exhibits superior performance.

Abstract: Purpose: The purpose of this research is to detect vehicle types in various image conditions using YOLOv8n, YOLOv8s, and YOLOv8m with augmentation.Methods: This research utilizes the YOLOv8 method on the DAWN dataset. The method involves using pre-trained Convolutional Neural Networks (CNN) to process the images and output the bounding boxes and classes of the detected objects. Additionally, data augmentation applied to improve the model's ability to recognize vehicles from different directions and viewpoints.Result: The mAP values for the test results are as follows: Without data augmentation, YOLOv8n achieved approximately 58%, YOLOv8s scored around 68.5%, and YOLOv8m achieved roughly 68.9%. However, after applying horizontal flip data augmentation, YOLOv8n's mAP increased to about 60.9%, YOLOv8s improved to about 62%, and YOLOv8m excelled with a mAP of about 71.2%. Using horizontal flip data augmentation improves the performance of all three YOLOv8 models. The YOLOv8m model achieves the highest mAP value of 71.2%, indicating its high effectiveness in detecting objects after applying horizontal flip augmentation. Novelty: This research introduces novelty by employing the latest version of YOLO, YOLOv8, and comparing its performance with YOLOv8n, YOLOv8s, and YOLOv8m. The use of data augmentation techniques, such as horizontal flip, to increase data variation is also novel in expanding the dataset and improving the model's ability to recognize objects.
