  • The e-commerce fashion market has experienced a remarkable growth, leading to an overwhelming availability of shared information and numerous choices for users. In light of this, chatbots have emerged as a promising technological solution to enhance personalized services in this context. This study aimed to develop user-product attributes for a chatbot-based personalized fashion recommendation service using big data text mining techniques. To accomplish this, over one million consumer reviews from Coupang, an e-commerce platform, were collected and analyzed using frequency analyses to identify the upper-level attributes of users and products. Attribute terms were then assigned to each user-product attribute, including user body shape (body proportion, BMI), user needs (functional, expressive, aesthetic), user TPO (time, place, occasion), product design elements (fit, color, material, detail), product size (label, measurement), and product care (laundry, maintenance). The classification of user-product attributes was found to be applicable to the knowledge graph of the Conversational Path Reasoning model. A testing environment was established to evaluate the usefulness of attributes based on real e-commerce users and purchased product information. This study is significant in proposing a new research methodology in the field of Fashion Informatics for constructing the knowledge base of a chatbot based on text mining analysis. The proposed research methodology is expected to enhance fashion technology and improve personalized fashion recommendation service and user experience with a chatbot in the e-commerce market.

  • This study aims to develop a comprehensive technological framework anchored in a theoretical model to assess user satisfaction with university library websites (ULWs) in Myanmar. Adopting a quantitative approach, data were obtained via convenience sampling and subsequent inferential analysis. The target population for this study investigated users of various ULWs in Myanmar who were utilizing six university libraries. Of the collected responses, 273 valid surveys were analyzed using SPSS (version 25) and AMOS. Tools such as structural equation modeling and confirmatory factor analysis played pivotal roles in data interpretation and hypothesis validation. The proposed model highlights the significance of information quality, system quality, and librarian services in influencing both perceived usefulness (PU) and perceived ease of use (PEOU), culminating in user satisfaction. Notably, information quality and librarian services primarily impact PU, while system quality is more influential on PEOU. Interestingly, while PU has a direct bearing on user satisfaction, PEOU does not. Moreover, demographic elements such as age, gender, and education level introduce considerable differences in the utilization of ULW services. Drawing from the study's findings, recommendations are made for ULW managers in Myanmar to bolster services, aligning with user preferences. The resulting framework offers tangible benefits to Myanmar's educational sector, including academia, government entities, librarians, and policy framers. This pioneering research delves into the realm of ULWs in Myanmar's higher education sector. Practically, the research underscores the necessity for stakeholders, encompassing Myanmar's library experts and governing bodies, to elevate the standard of ULWs. Theoretically, a salient takeaway is the direct linkage between heightened usefulness and increased user satisfaction.

  • The article examines the key constants of reengineering the modern educational cluster, associated with the processes of digital transformation of all spheres of modern socio-cultural space. The first constant is the strategic rethinking of the educational process organization and awareness of the new roles of all participants (tutors, applicants, controlling elements, etc.). The other constant involves practical re-design of the system of educational services, which consists in the reorientation from the traditional model of education functioning for society to the implementation of the educational format in the form of new projects (structural, target, business). Consequently, the purpose of the study is to highlight the attitudes relevant to the modern realities of information and technological support of education in the context of socio-economic interactions of society. The criteria for the reengineering of educational concepts and the structural organization of the educational sphere are defined. The modern world is going through a period of complete digital transformation of all spheres of public activity. The scientific intelligence notes that education is no exception in these processes, as the dependence of educational realities on information and computer technologies is now noted. The COVID-19 pandemic, for all its tragedy, was also a kind of trigger, clearly marking the new components that have become defined in the organization of the educational process. The conclusion is made that the use of digital technologies in the organization of the educational institution or in the organization of the educational process has become not an auxiliary element, but a dominant factor. Mobility, dynamism, interdisciplinarity, synergy - all these aspects are relevant for socio-economic interactions of society and should be provided by educational programs. The results of the study can be used in the reorganization processes of educational institutions and institutions. Further research requires aspects of the analysis of the foreign experience of reengineering in education, carried out taking into account digital transformations of modern sociocultural space.

  • The purpose of this study was to research modern reinterpretation of traditional Chinese culture and design development of fashion items in the context of globalization and technological advancements, reflecting fashion demands of young female consumers in their 20s in China. To achieve this, this study investigated fashion preferences of young women in major Chinese cities, focusing on design elements such as form, details, patterns, and colors in 'New Chinese Style' fashion. Results indicated a high preference for overlapping collars, Mandarin collars, oblique front pieces, and slit sleeves. Additionally, there was a strong preference for natural and eco-friendly materials such as plant dyes and embossed velvet. Based on survey results and analysis of the popular brand 'TUYUE,' this study proposed two design themes. The first theme, 'natural symbiosis,' focused on casual wear with a soft and free image with a simple design. The second theme, 'chivalrous guest,' targeted work attire with minimal designs emphasizing power and confidence. Both themes aimed to meet aesthetic and practical needs of modern women by incorporating overlapping collars, asymmetrical front pieces, slit sleeves, and preferred colors and patterns. In conclusion, although this study was limited to design preferences of young Chinese women in their 20s, results offer valuable direction for future design innovation, contributing to sustainable development of the fashion industry and the preservation and innovation of traditional culture.

  • Visual Effects have been revered as 'Spectacular' film elements for a long time, and once there was a misunderstanding that they destroyed the actual 'Story'. But, now they are becoming a valuable tool for storytellers. A film pursues a perfect narrative structure and visual reality so that the audience can believe the story as a real. Giving a narrative motif to the audience, they use Visual Effects that provide the technical solutions and -at the same time- they create and preserve the diegetic world that Is either believable or not. This research suggests that we analyze precisely and make a classified table of the narrative use of Visual Effects based on the previous research of Shilo T. McClean. First, we can ask if the narrative motif would be there in front of the camera, From there, we then can get two desired answers. One is, if there is nothing to visually stand up, Visual Effects can intervene as an alternative tool for creating the diegetic world. The other is that Visual Effects can be used for preserving the diegetic world as a necessary tool. Then, in the latter, we can consider whether there is a storyteller's purpose to be added, so we can distinguish the details. This classified Visual Effects for the narrative is able to dispense proof that they can be worthy as to provide a 'Spectacuiar' aura as to create and preserve the diegetic world. I would like to argue that this research could be a foundation for the inter-progress of future studies for visual effects as well as for their amazing technological improvements.
