With technology advancing quickly in today's world, education has become one of the significantly affected aspects. Technological progress facilitated access to educational materials, leading to the emergence of various new learning methods, including online courses. Online courses were widely favoured due to the customization and diverse variations of their learning materials. Visual design, user interface (UI), and user experience (UX) played a crucial role in attracting interest in learning, as evidenced by increased engagement among users of online courses with appealing designs. These critical UI/UX aspects provided a specific boost in understanding and exploring this field, as reflected in the provision of UI/UX materials on online course platforms. This study utilized the User Experience Questionnaire (UEQ) method to evaluate the satisfaction and experiences of students participating in UI/UX online courses across six aspects: Attractiveness, Efficiency, Perspicuity, Dependability, Stimulation, and Novelty. The study involved 41 students who took UI/UX online courses for one month. The results indicated a high level of satisfaction across these aspects, suggesting that UI/UX online courses could be considered effective and reliable methods for understanding and exploring this field.

Facial Emotion Recognition (FER) is a key technology for identifying emotions based on facial expressions, with applications in human-computer interaction, mental health monitoring, and customer analysis. This study presents the development of a real-time emotion recognition system using Convolutional Neural Networks (CNNs) and OpenCV, addressing challenges such as varying lighting and facial occlusions. The system, trained on the FER2013 dataset, achieved 85% accuracy in emotion classification, demonstrating high performance in detecting happiness, sadness, and surprise. The results highlight the system's effectiveness in real-time applications, offering potential for use in mental health and customer behavior analysis.

This study investigates directive speech acts in Chapter 1 of the Japanese manga *Dandadan*, focusing on how characters use language to influence others’ behavior. The objective is to classify the types of directive utterances and analyze their pragmatic functions based on the speaker and context. A qualitative descriptive method was employed, using pragmatic theory to analyze speech data taken directly from dialogue panels. The analysis identified nine instances of directive speech acts, which include commands, prohibitions, invitations, and requests. Ayase Momo emerges as the character who produces the most directive utterances, predominantly in the form of commands and prohibitions, indicating her dominant and assertive communication style. Okarun, in contrast, tends to use polite requests and prohibitions, suggesting a more cautious and respectful approach. The findings reveal that the types of directive speech acts used are closely related to each character’s personality and the emotional context of the scene. These results underscore the role of speech acts in character development and narrative dynamics within manga. The study’s implication lies in showing how linguistic choices in manga dialogue reflect interpersonal power relations and emotional intensity. Future research is encouraged to explore directive speech acts across multiple chapters for broader insights.

This research focuses on the development of a freelance e-commerce website for WardellTech using the Laravel framework. The objective is to build a web-based platform that is secure, responsive, and user-friendly, supporting freelance service transactions. Laravel was selected for its structured MVC architecture, built-in security features, and its ability to streamline development and maintenance. A Software Requirements Specification (SRS) document was created to define both functional and non-functional requirements in detail, ensuring that all stakeholders—developers, testers, and project managers—have a unified understanding of the system. WardellTech specializes in web and mobile application development, emphasizing quality design, user experience, and data security. Therefore, the website integrates key features such as secure payment gateways, intuitive navigation, and optimized performance. Continuous analysis and improvement of the user interface are also prioritized to enhance usability and customer satisfaction. The final system is expected to not only meet WardellTech’s business needs but also compete effectively in the freelance digital services market. Additionally, it is designed to adapt to ongoing technological advancements and evolving user demands in the dynamic e-commerce landscape.
