Effectiveness Analysis of Lane Detection and Warning Systems in Multi- Environments
Abstract : This study aimed to derive the quantitative effects of the lane recognition and warning system, one of the ADASs developed and commercialized to ensure the safety of road users in a multi- environment. In past studies, the effects were estimated based only on traffic accident data, making it difficult to determine the independent effects of the lane recognition and warning system. For this reason, this study analyzed the quantitative effects not in terms of traffic accidents, but rather as ive measures of effects such as driver reaction speed and number of departures. A driving simulator was used with 70 drivers, and experiments were conducted during the day and night, with and without the lane recognition and warning system installed. The results of the experiment showed that the lane recognition and warning system was effective for drivers who did not recognize the lane and departedthe lane during night driving, and the time of lane departure decreased with the installation of the system. However, the number of lane departures slightly increased, which can be considered to be a problem of decreased attention due to the increased dependence of the driver on the system.

Abstract : After COVID-19, travel patterns have become increasingly segmented, leading to a rise in demand for personalized travel products. In response to this trend, this study analyzed the user experience of personalized service features in three major travel applications: HanaTour, Triple, and Yeoda. The research methodology involved conducting surveys and in-depth interviews with male and female users who utilized the travel itinerary creation services within these applications. For the analysis, Peter Morville’s Honeycomb Model was applied, evaluating seven key factors: useful, credible, usable, convenient, accessible, desirable, and value. The findings revealed that users expressed high satisfaction with features that allowed them to easily plan and organize their travel itineraries, with simpler and more intuitive interfaces receiving particularly positive feedback. Therefore, in order to enhance usability, travel applications should incorporate intuitive interface designs while ensuring that users have the autonomy to create and modify their itineraries freely. This study provides a systematic analysis of user experiences with personalized travel services and is expected to serve as valuable reference material for improving and developing related services in the future.

Abstract : This study aims to analyze the impact of users' motivation and IT affordance on purchase intention in the Chinese second-hand trading platform Xianyu App and to examine the mediating role of payment convenience in these relationships. A total of 501 valid questionnaires were collected and analyzed. The results of the analysis are as follows. First, the key motivational factors for using the Xianyu App were identified as locality, economic benefit, and trust. Second, all three motivational factors were found to have a significant positive effect on purchase intention. Third, the three dimensions of IT affordance—visibility, shopping guidance, and meta-voicing—also had a significant positive impact on purchase intention. Fourth, the mediating role of payment convenience was confirmed, indicating that payment convenience partially mediates the relationship between user motivation (locality, economic benefit, and trust) and purchase intention, as well as the relationship between IT affordance (visibility, shopping guidance, and meta-voicing) and purchase intention. This study contributes to a deeper understanding of users' motivations and purchasing decisions in second-hand trading platforms, providing theoretical support for optimizing these platforms and enhancing user experience. Furthermore, the findings of this study serve as a valuable foundation for future research in this field.

Abstract : The purpose of this study is to study the characteristics of character influencer, focusing on para-social interaction, centering on Instagram characters. As the webtoon industry develops around large platforms, the quantitative expansion of users and works is rapidly taking place, and as a result, webtoons can be easily found on platforms such as SNS due to their attractiveness to content diversity. Since Instagram characters act as influencer and interact by increasing intimacy with readers, consumers' preference and use of SNS webtoons such as Instagram, which are provided for free, is high. Accordingly, three works were selected for everyday cartoons featuring artist characters, and all three works were analyzed to have attractiveness, intimacy, professionalism, and reliability as influencer. In addition, as a influencer with a large number of subscribers, it has been studied that para-social interactions with readers are active. In the future, it is expected that various SNS platform-based webtoons genres, diversity of contents, and research on webtoon characters will be expanded.

Abstract : The Stele for Buddhist Monk Tongil at Gagyeonsa Temple in Goesan is evaluated as a stone cultural heritage with high historical, academic, and artistic value, built during the Goryeo Dynasty. However, it has been damaged due to complex causes as it has been exposed to the outdoor environment for a long time. Therefore, non-destructive investigations such as visual examination, weathering damage assessment, and ultrasonic velocity measurement were conducted to diagnose the damage status. As a result, the biological damage rate of the tower stele was the highest at 75.8% on the east side, followed by similar rates of 59.6% and 58.1% on the north and west sides, respectively. In addition, physical damage rate was the highest at 40.4% for peeling and delamination on the north side. Chemical damage rate was 67.1% on the east side, 56.6% on the north side, and 53.5% on the west side. In addition, the weathering index results showed that the order of the dragon top of the stele, the turtle-shaped pedestal, and the stone body was high, and in the case of the capstone, the weathering index tended to increase as it went up to the wish-fulfilling jewel. The weathering grade of each component corresponds to an average rock between grades 3 and 4. Such damage has the potential to change the original shape of the stele, so conservation treatment and periodic management are necessary.

A Study on the Protection of Package Disposition Exhibition -In terms of design elements-
Abstract : Taking issue with the low percentage of correct answers to separate collection methods by consumers, we tried to present design elements as a way to activate the separate discharge mark, and as a result of a survey to find out the reality and knowledge of the separate discharge mark, the current separate discharge mark was receiving positive responses in terms of functional, practical, and aesthetic aspects, but in the case of visual perception, it was difficult to recognize due to its small size. Satisfaction was low in the suitability of information provision, which can be interpreted as not difficult to discharge using the mark in case of simple discharge, but the package date and time combined with multiple materials cannot be easily understood with the current mark. In terms of improvement measures, respondents felt the need to supplement them and agreed that they were suitable methods to induce correct discharge in relation to the addition of illustration elements, phrases, and size adjustment, and prototypes were completed based on the results. At a time when various packages are released with the development of the times and the importance of environmental issues increases, it is hoped that improvement measures and activation studies for correct separation discharge will have academic significance for environmental protection.

Hongdo Kim's 〈Hwangmyo Nongnyeok〉 XR Content Production
Abstract : It is self-evident that materials that can make the most of the advantages and characteristics of the region and local culture will have a competitive advantage in content creation.this perspective, I'd like to develop 〈Hwangmyo Nongchap〉, a work by Kim Hong-do, who worked in Ansan, as a local cultural content. The application of XR technology to the production of Joseon paintings as digital contents is a new way to preserve and disseminate cultural heritage. In this paper, we explore how XR technologies, including VR, MR, and AR can be used to create an immersive experience of Joseon paintings. In recent years, there have been dozens of studies on the cases and methods of applying immersive content to cultural heritage, but there are only a few studies that have directly created immersive local cultural heritage content and evaluated the impact of XR technology on the preservation and dissemination of local cultural heritage. Therefore, this study aims to investigate the feasibility and suitability of XR for local cultural heritage by implementing immersive local cultural heritage contents with XR technology. Based on the results, I propose a strategy for the development of immersive local cultural heritage content and contribute to its application to various cultural heritage contents in the future.
