PURPOSES : Basic research to calculate the appropriate gap acceptance for autonomous vehicles at merging section. Research on whether users prefer short or long gap acceptance. METHODS : Using a driving simulator, experience autonomous driving with different gap acceptance in different weather condition, and analyze which gap acceptance is preferred using survey and biometric data. RESULTS : Regardless of the weather condition, long gap acceptance was preferred, and difference was especially clear in rainy or foggy situation. CONCLUSIONS : It was analyzed that users prefer long gap acceptance over short gap acceptance, and that they feel less frustrated due to long gap acceptance when weather condition is poor.

PURPOSES : Evaluation of the effectiveness of changing the form of yellow carpet installation as a way to reduce child pedestrian traffic accidents. METHODS : Through expert opinion, two improvement plans for yellow carpet installation (oblique type, extended type) were derived. The improvement paln was built in virtual reality, and a virtual driving experiment was performed using a driving simulator and eye-trakcing device. The improvement effects of the two alternatives were evaluated by analyzing eye-tracking data and driving behavior. RESULTS : In the case of the oblique type, it was analyzed that it was effective in improving the total gaze time and first gaze position compared to the normal type. In the case of the extended type, it was analyzed that the workload during operation can be reduced. However, neither of them had a significant effect on driving behavior. CONCLUSIONS : Although the change in the yellow carpet installation type did not affect the driver's driving behavior, it had advantages in terms of visual behavior and workload while driving, so it can be considered as an alternative among measures to improve traffic accidents involving children and pedestrians.

In this study, complaints from visitors in the science museum satisfaction survey were categorized into four primary factors and ten sub-factors. This categorization aimed to provide recommendations for enhancing the Geochang Wolseong Space Creative Science Museum as an illustrative case study. Futhermore, the study examimed the relative importance of each factor by surveying 90 science museum visitors. The following results are obtained. Firstly, it was evident that the Geochang Wolseong Space Creative Science Museum requires urgent improvement. Certainly, in the primary factors, issues related to the utilization environment emerged as the most significant sources of dissatisfaction, while in the sub-factors, the adequacy of fees was identified as the most prominent concern. Secondly, through the result of the IPA (Importance-Performance Analysis) of the complaint factors, four primary issues were identified as top priorities for consideration: fare adequacy, lack of convenient facilities, in sufficient publicity, and a lack of distinctiveness compared to similar facilities. Lastly, when analyzing the relationship between complaints and overall satisfaction, factors related to human service, environment, and educational content had negative effects. In contrast, factors associated with science museum operation exhibited a different trend, suggestinga structural impact relationship with the overall impact of complaints.

In this study, a smart bench was developed and researched smart benches that can contribute to user convenience and satisfaction by installing them in parks, bus stops, and tourist attractions in line with the rapidly changing construction of smart cities. The smart bench is automatically operated by the control system according to the external temperature and provides additional functions such as charging, lighting, and advertising to improve general bench functions as well as heating in winter and cooling in summer, making it suitable for smart urbanization. The developed smart bench is designed to be strong enough to withstand loads of about 2,500 N. It minimizes the visible parts such as assembled bolts and 220V power supply wires, It can also give aesthetic effects. The development was carried out with the aim of waterproofing and dustproofing of IP44 grade in accordance with the climate of Republic of Korea, which has four seasons, and it is advantageous for long-term use because the paint was selected for the weather ability (discoloration) grade 3 or higher. If smart bench is commercialized, it is believed that various options can be provided to the smart bench market, where buyers had few product options, as the parts were developed in an assembled type so that all functions can be responded in an optional form according to the installation environment and the buyer's budget.

Humans turn to other humans for decision making. They don’t know how the algorithm operates but they understand how a human mind operates. Ergo, they would be more likely to follow a human’s recommendation.

Even though Mod is a cutting-edge business model that benefits a variety of multi-sided market participants, empirical research on Mod, the value co-creation activity of game users and game developers, is hard to come by. This study intends to look into how the combination of the Mod and the IP from the prior game affects user engagement. An experiment was carried out with Korean university students to examine the hypotheses. User engagement was found to increase with the use of the Mod and the IP from the previous games. On the other side, it was discovered that the impact of mod games on user engagement did not differ significantly from non-mod games when the previous game's IP was absent. The study's findings help establish the framework for afterwards empirical research by showing the effect of mod on user engagement.

Social media have emerged as one of the most important tools for firms to engage customers (e.g., Chandrasekaran et al., 2022; Cheng & Edwards, 2015; Lee et al., 2018; Wedel & Kannan, 2016). Within the tourism industry, scholars have investigated the role of social media communication in various contexts, such as online travel information search (Xiang & Gretzel, 2010), sharing travel experiences (So et al., 2018; Wang et al., 2022) and establishing positive customer relationships (Jamshidi et al., 2021). Insights into which social media content makes for generating positive engagement are, however, still largely based on marketers’ intuitions or focusing on message factors of social media posts such as message appeals (e.g., Wang & Lehto, 2020). It also often neglects the importance of the visual component of social media posts, and only a few research have investigated the effects of the image in social media on the travel industry (e.g., Fusté-Forné, 2022). The objective of this research is, therefore, to understand how textual features and image features generate user engagement in social media utilizing cutting-edge transfer learning techniques and to propose how these features should be customized to maximize user engagement for online travel shopping companies. We collect and analyze more than 10,000 Instagram posts from three online travel shopping companies, including Expedia, Priceline, and Kayak. The results from transfer learning algorithms utilizing 24 features, such as the number of people in the image, emotions expressed in the people in the image, hue, and RGB value, successfully predict the level of engagement measured by the number of likes and comments.

Voice assistance (VA) has been widely adopted in the tourism and hospitality industry to interact and communicate with tourists and provide useful travel recommendations. Although more companies in tourism have adopted environmental sustainability practices and tourists have increased their sustainability awareness, lack of research has been conducted to investigate the effectiveness of VA in promoting sustainable consumption of tourism products or services. This study proposes that customising environmental sustainability messages for tourists with different cultural orientations and VA use purposes can enhance their engagement with the VA, which can affect their consumption decision. The results from a scenario-based experiment demonstrate that tourists with interdependent/independent cultural orientation have higher engagement with the environmental sustainability messages communicated by the VA when they are with a non-transactional/transactional purpose. Implications for tourism marketing strategies are discussed.

This research presents a conceptual framework for a comprehensive understanding of the causes of user migration from social media networking sites. The results of our survey show that users’ intentions to switch social media platforms are influenced by user satisfaction, alternative attractiveness, peer influence, and perceived switching costs.

As one of the biggest service-oriented industries worldwide, the hotel industry significantly contributes to environmental degradation in several ways. Service marketers, consumers, and policy makers are increasingly aware of the damage that excessive natural resources depletion in the guise of water and energy consumption and CO2 emissions by hotels might bring about to the planet. As a result of the growing global concern about climate change, there has been an increase in consumer demand for environmentally-responsible hospitality options. One such option is green hotels, which are environmentally-conscious hospitality properties that are gaining popularity worldwide at a rapid pace. Consumers who prioritize eco-friendliness are willing to pay a premium for green hotels. However, unlike tangible products, services such as hotel experiences are subjective, emotional, and therefore, difficult to evaluate before actual usage. One of the prominent ways in which consumers assess green hotels’ credibility is through user generated content in the form of reviews.

In recent years, the trend of customer demand and personalization has become more and more obvious. The previous innovation model can no longer meet the diversified needs of consumers. Therefore, firms vigorously develop open innovation to promote internal and external innovation (von Hippel, 1988). With the rapid development of AI technology, open innovation communities have more interactions with the users. Organizations continue to rely on their open innovation community to collect innovative ideas from non-professional customers and then integrate them into their new product development process to produce innovative products that are more in line with customer preferences (Bayus, 2013). At present, the research on user design focuses on how to increase user design implementation and the idea popularity (Yang et al., 2022; Zhang et al., 2022). Few studies discussed how to motivate consumers to participate in innovative content output from the source. In addition, academic research on user design is mostly limited to management comments, lacking in-depth empirical research (Franke et al. 2008). Previous studies have proved that the number of leading users in the open innovation community is far less than that of non-leading users (Hofstetter et al., 2018), so it is very necessary to improve the willingness of users to participate in community creative activities. With the vigorous development of the new technology, it is an urgent problem to be solved to encourage users to participate in innovation activities and improve the innovation performance of firms (Chesbrough, 2012). Today, firms pay more and more attention on the implementation of AI technology. With AI and user design as the research background, “AI recommendation” and “willingness to design” as the key variables, and the “S-O-R model” and “Self-determination Theory” as the basis, this paper deeply explores whether AI recommendation can be used as a factor affecting user’s participation in design activities from the perspective of users, focusing on the intermediary role of user’s inspiration, competency and self-expression. It also puts forward that product involvement and aesthetic experience openness (Donghwy and Youn, 2018) are the boundary conditions that affect user’s willingness to participate in design. The results show that user’s willingness to participate in design is higher when providing AI recommedation, and the sense of inspiration, competence and self-expression play a mediating role in it. Furthermore, the results show that when product involvement is high, users are more willing to participate in design. Similarly, users with a high degree of aesthetic experience openness are more willing to participate in design activities. This study enriches the theory of enterprise community management, promote the internal information flow of the open innovation community, and provide theoretical guidance and reference for firms to optimize the new product design process.

통합항해시스템(INS)은 기존 항해 장비들을 통합하여 부가가치를 제공하는 장치로써 항해 업무 수행을 위한 정보와 기능을 다기능표시장치에(MFD)에 통합하는 것으로 정의된다. IMO 성능 기준은 각 업무에 대한 최소 요구사항을 명시하고 있지만, 장비 및 기 능의 목록은 정의하지 않아 제조사마다 INS의 구성이 상이하고 사용자 관점에 기반 한 지침 또한 부족한 실정이다. 본 연구는 선박 운 용상황 및 수행 업무에 따라 사용자가 요구하는 정보를 분석하고, 이를 INS의 MFD에 효과적으로 구조화하여 INS의 사용성을 높이기 위해 수행되었다. INS 관련 국제 기준 및 제조사의 구성 장비 목록을 분석하여 필수 항해 정보들을 선별하고 MFD 사용 경험이 있는 선박 운항자를 대상으로 카드 소팅 테스트를 실시하여 각 INS 업무에 요구되는 정보들을 분류하도록 하였다. 연구의 결과는 제조사들 이 제품 설계 시 사용자 경험을 반영한 정보 구성에 기본적인 가이드로 활용될 수 있을 것이다.

Identifying plausible scenarios is necessary to evaluate the performance of the repository reliably over a very long period. All features, events, and processes (FEPs) expected in the repository should be comprehensively well-defined and structured into scenarios based on the relation analysis. A platform for the FEP DB management and relation analysis is needed to facilitate the efficient composition of the scenarios. For this purpose, the CYPRUS program was developed, but abandoned due to suspended FEPs and scenario research. Thus, it became necessary to build a new easy-tomaintain platform that inherits the legacy of CYPRUS and reflects the latest research. The data structure and user interface configuration were derived to develop a new platform. The new platform provides extensive data such as the assessment context, the FEP DB, the interaction between FEP contents, the relevance to other project FEPs, the influence on performance, the scenarios for the TSPA, the AMF, and the PA Data. The platform displays the long-term evolution FEPs developed by KAERI, the international and major project FEPs in table format. The correlation between FEP items is composed of a detailed interaction matrix and visualized as the chord diagram or arc diagram. The relevance and linkages between the project FEP items are mapped and presented in the form of network diagrams and network tables. The platform designed in this study will be used to manage the FEP DB, analyze and visualize the relationship between the FEP and scenarios, and finally construct the performance assessment scenarios. It is expected that the platform itself will be used as a part of the knowledge management system and facilitate efficient collaboration and knowledge exchange among experts.

본 연구의 목적은 음성 인터페이스(Voice User Interface, VUI)를 이루는 설계변수 중 사용자에게 긍정적인 감성을 유발하는 설계변수를 확인하는 것이다. 특히, 사용자의 성별과 설계변수의 조절 효과를 분석하여 VUI와 상호작용하는 동안 사용자가 만족할 수 있는 적절한 설계변수 수준을 찾아보고자 하였다. 선행연구를 통해 VUI에 사용되는 음성 설계변수 중에서 사용자의 감성 만족도에 영향을 미칠 수 있는 설계변수 6가지를 도출하였다. 설계변수는 수준을 조절할 수 있도록 Wizard of OZ를 활용하여 VUI 시스템을 구현하였고, 6가지 설계변수의 수준을 조합하여 사용자와 음성으로 대화를 할 수 있도록 구성하였다. 실험에 참여한 사용자는 총 80명으로, 남/여 성비를 고려하여 각 40명씩 모집하였다. 사용자는 VUI와 주어진 임무에 대한 정답을 알아내기 위해 자연스러운 대화를 진행하며, 그동안의 얼굴 표정 변화에 대한 이미지 데이터를 수집 및 표정 분석 소프트웨어를 통해 Valence 점수로 변환하였다. Valence 데이터 를 기반으로 빈도 및 카이제곱 분석을 통해 확인한 결과, 사용자의 성별과 AI gender간의 조절효과가 유의한 것으로 나타났다. 이 결과는 VUI를 설계할 때 사용자의 성별 차이를 고려하는 것이 좋다는 것을 의미한다. 결론적으로, 남성사용자의 경우 성인/남성/높은 톤의 음성, 여성 사용자의 경우 성인/여성/중간톤의 음성이 향후 만족스러운 인터랙션 구현을 위한 VUI 설계에 주요한 가이드라인인 것을 확인하였다. 본 연구의 결과를 통해 향후 다양한 인적 요소를 고려하여 UX 관점에서 인간-AI 상호작용을 보다 섬세하게 분석할 수 있을 것이며, 표정을 통한 실시간 감성 측정을 위한 기초연구로 활용될 수 있을 것이다.

본 연구는 의인화와 긍정적인 사용자 경험의 기제를 밝히기 위해 수행되었다. 이때 CASA (Computers Are Social Actors) 패러다임 접근법을 차용해 사회적 반응과 의인화의 인과관계를 검증하고 이 패러다임에 대한 올바른 이해를 도모했다. 본 연구는 대인관계에서 나타나는 깊은 자기개방의 친밀감 형성 및 의인화 효과를 사람과 대화형에이전트 의 관계에 적용해 사회적 반응과 의인화를 모두 유도했다. 그리고 친밀감으로 치환되는 사회적 연결감과 의인화의 인과관계를 밝히는 심리학 모델로 깊은 자기개방의 의인화 효과에 대한 친밀감의 매개효과를 탐색했다. 더 나아가 대인 특성이 적용된 에이전트 사용 경험이 긍정적으로 나타나는 데 친밀감과 의인화가 어떻게 관여하는지 탐구했다. 연구 결과, 자기개방 깊이가 깊을수록 에이전트가 더 친밀하고 사람답게 지각됐으며, 사용자 경험이 더 긍정적이었 다. 그리고 자기개방 깊이가 의인화와 긍정적인 사용자 경험에 미치는 영향을 친밀감이 완전히 매개하였다. 사람이 사회적 단서를 가지는 대상에 사회적으로 반응하기 때문에 대인 특성이 반영된 컴퓨터를 의인화하고 긍정적으로 평 가하는 것이다. 본 연구는 CASA 패러다임과 의인화 연구를 연결하며 인간 - 컴퓨터 상호작용에 대한 심리학적 설명 가능성을 시사한다. 그리고 의인화와 긍정적인 사용자 경험의 충분조건으로서 사회적 반응 즉, 친밀감의 중요성을 강조한다.

수의사 보조원은 동물병원에서 동물에 대한 처치, 접수, 보호자 안내, 수납 업무 등을 통해 수의사를 지원하고 보조한다. 이러한 역할을 수행하기 위해서는 적극적 경청과 원활 한 의사소통 능력을 갖춰야 한다. 이것과 관련하여 조사와 분석을 통해 도출된 결과로 인 식의 함양이 필요하지만 현재 이와 관련된 선행연구가 부족한 실정이다. 본 연구는 동물 병원 서비스 이용 경험이 있는 전라북도 반려인의 이용 만족도 현황과 정도를 파악하고 이에 수의사 보조원의 언어적, 비언어적 의사소통 능력이 미치는 영향의 유무를 규명하고 자 한다. 또한, 전반적인 의사소통 능력의 중요성과 영향력을 인식하는 데 목적을 둔다. 2022년 4월 30일부터 2022년 5월 29일까지 온라인 설문조사를 실시하였다. 응답 결과 의 데이터는 빈도 분석, 신뢰도 분석, 상관 분석을 사용하여 인구통계학적 기준으로 분석 하였다. 첫째, 수의사 보조원의 언어적, 비언어적 의사소통 능력의 개념을 정리하기 위한 신뢰도 분석 결과 Cronbach’s alpha 계수는 모두 0.8 이상으로 나타나 신뢰도가 검증되 었다. 둘째, 수의사 보조원의 언어적, 비언어적 의사소통 능력이 동물병원 이용자의 만족 도에 미치는 영향의 여부와 정도를 파악하기 위해 상관분석을 실시하였다. 그 결과 모두 정(+)의 상관관계로 나타났다. 하여, 본 연구는 수의사 보조원의 언어적, 비언어적 의사 소통 능력의 영향력 인식을 통해 중요성 함양하고자 하는 데 의의가 있다.
