Performance Evaluation of Convolutional Neural Network Using Superpixel Representations
Abstract : Recently, the integration of Robotic Process Automation (RPA) and Artificial Intelligence (AI), known as Intelligent Process Automation (IPA), has made a significant impact across various industries. However, its application in medical image analysis remains in the early stages. This study proposes a convolutional neural network (CNN)-based image classification system for diagnosing pneumoniachest X-ray images and compares the performance of models using original image data versus superpixel-based representations. Experimental results show that the superpixel-based CNN outperforms the original image-based model in terms of test accuracy, recall, and F1-score, particularly demonstrating higher recall for the pneumonia class, indicating its effectiveness in disease detection. Furthermore, the superpixel-based model exhibits greater stability in terms of training convergence speed and validation accuracy, suggesting superior generalization performance. These findings imply that the superpixel-based approach preserves structural features of medical images more effectively and enables robust learning against noise. As a meaningful case of applying IPA to medical image analysis, this study highlights the potential of improving diagnostic accuracy while contributing to enhanced operational efficiency, reduced diagnostic costs, and decreased patient wait times in medical institutions.

Abstract : Recently, music production systems that utilize generative artificial intelligence have been proliferating rapidly, making it easier for users to create music. In these systems, emotional vocabularies are used as the primary means of specifying the moodemotion of the music, acting as an emotional interface between the user and the system. However, the interfaces of currently commercialized AI music generation systems are organized around a limited number of structured emotion labels, which raises the issue of mismatch with the emotions that real users recognize and want to express. Based on this problem, this study exploratively analyzed the extent to which the emotional vocabulary of generative AI-based music generation systems accommodates real user language. To this end, we conducted experiments on 15 users to derive emotional vocabularies after listening to music and label them using card sorting techniques. The results showed that the match between user emotional vocabulary and commercial systems was very low, and that users' expressions reflected more granular and subjective emotional states. The results of the study suggest that the emotional interface of generative AI music systems needs to be redesigned to be more user-centered. This study provides a basis for interface design of emotion-based AI systems through empirically-based analysis of user emotional vocabulary and confirms the importance of strengthening user-system emotional communication.

Strategies for Utilizing Big Data in Traffic Volume Surveys
Abstract : This study aims to identify the limitations of road traffic volume statistics and propose improvement measures through the integration of external big data such as accident records, Digital Tachograph (DTG) data, and weather and air pollution information. A mixed-methods approach was used, combining a survey of traffic experts and a Focus Group Interview (FGI). Survey results showed that experts recognize limitations in real-time usability and data structure, with strong support for linking traffic data with accident (33.3%), DTG (24.8%), and weather data (23.4%). Additional data needs—such as speed, cumulative volume, and individual vehicle records—were also highlighted. FGI discussions emphasized the need for unified ID systems, consistent classification schemes, and improved documentation. Experts further stressed the importance of standardized, integrated data systems to enhance analysis and practical use. These findings suggest the urgent need to transitionstatic statistics to a big data-based, real-time traffic information framework that can support predictive analytics and effective policy development.

Abstract : This study aims to theoretically structure the sensory-based mechanism of sense of place and develop a validated evaluation framework applicable to spatial UX design. Core constructs such as placeness, sensory perception, sensory immersion, sense of place, and behavioral intention were defined, and survey items were initially developed based on prior studies on sensory UX and place experience. To refine these items, expert evaluations were conducted with five professionals in spatial design, UX, emotional engineering, and urban planning, based on five criteria: theoretical validity, structural fit, linguistic clarity, sensory recall inducement, and analytical feasibility. The final survey consists of 34 items, including 31 closed-ended and 3 open-ended questions, categorized into seven domains: place recall, placeness, sensory perception, sensory immersion, sense of place, behavioral intention, and sensory impression. Each item reflects theoretical definitions and subcomponents of its variable and uses a 7-point Likert scale to quantitatively assess users' emotional and behavioral responses. This instrument offers practical value for identifying sensory-based user reactions in early design stages and supporting emotional UX strategy development.

A Study on Use and Satisfaction of Autonomous Vehicle Indoor Space Focused on Generation Z
Abstract : As the recent mobility trend considers vehicles as simply another space in terms of transportation, methods of utilizing indoor space and consumer awareness have become very important. Electric vehicles require fewer parts than internal combustion vehicles, and their structure is simple, allowing them to use indoor space in a much more relaxed and diverse way. To this end, it is necessary to analyze consumer indoor behavior in indoor space. However, user needs analysis and indoor space categorization based on the younger generation, the main customers who will use vehicles in the future, have not yet progressed much. Therefore, this study analyzed the indoor behavior of autonomous vehicles based on the Z generation. A survey was conducted based on the Kano model, and the satisfaction coefficient, dissatisfaction coefficient, and PCSI index were also used for accurate result values. As a result of the analysis, the Z generation in Korea wanted to make the most of the interior space of vehicles as a 'private space'. This study is meaningful in that it has identified how they are satisfied in using indoor space for the Z generation, and it is expected that a new indoor private space design can be made based on this.

Cultural Preservation in Black Myth Wukong: A Gameotics-Based Semiotic Analysis
Abstract : This paper examines how the action role-playing game Black Myth: Wukong preserves and reinterprets Chinese cultural heritage through a semiotic lens. Adopting the Gameotics framework, which cross-analyzes Peircean sign categories (icon, index, symbol) with digital game elements (aesthetics, mechanics, narrative), conduct a close reading of the game’s content to identify and clarify its cultural signifiers. By refining a previously complex semiotic matrix, our analysis highlights clear examples of iconic, indexical, and symbolic representations of Chinese mythology and traditions within the game. The findings indicate that Black Myth: Wukong faithfully integrates classic Journey to the West characters, settings, and themes into its design, thereby acting as a digital medium of cultural preservation and soft power. At the same time, the game balances authenticity with modern gameplay conventions, illustrating both the potential and the constraints of using Gameotics for cultural analysis. This paper conclude with a discussion of the method’s limitations in capturing dynamic cultural nuance and the implications of cultural adaptation in game design.
