  • Recently, with the development of artificial intelligence technology, many technologies for user convenience are being developed. Among them, interest in autonomous vehicles is increasing day by day. Currently, many automobile companies are aiming to commercialize autonomous vehicles. In order to lay the foundation for the government's new and reasonable policy establishment to support commercialization, we tried to analyze changes and perceptions of public opinion through news article data. Therefore, in this paper, 35,891 news article data mentioning terms similar to 'autonomous vehicles' over the past three years were collected and network analyzed. As a result of the analysis, major keywords such as 'autonomous driving', 'AI', 'future', 'Hyundai Motor', 'autonomous driving vehicle', 'automobile', 'industrial', and 'electric vehicle' were derived. In addition, the autonomous vehicle industry is developing into a faster and more diverse platform and service industry by converging with various industries such as semiconductor companies and big tech companies as well as automobile companies and is paying attention to the convergence of industries. To continuously confirm changes and perceptions in public opinion, it is necessary to analyze perceptions through continuous analysis of SNS data or technology trends.

  • The Critical Consciousness Scale (CCS) is a scale developed by Diemer and colleagues (2017) that can measure the capacity of the oppressed or marginalized people to critically analyze their social and political conditions, support societal equality, and take action to change the perceived inequities. In this study, we validated the CCS for Korea by adapting and localizing the scale and validating it among university students. Content validity was verified by having five individuals with master's and doctoral degrees in psychology evaluate the suitability of the translated items. Afterwards, reliability and validity were verified through a survey of 314 university students nationwide using the CCS, along with the opportunity inequality recognition scale, recognition of the need for environmental change scale, social participation scale, and belief in a just world scale. To verify the scale's validity, exploratory factor analysis was conducted, confirming three subfactors. Then, a confirmatory factor analysis was carried out, where 14 items out of the original 22 were retained. The construct validity and reliability of these 14 items were found to be satisfactory. Additionally, in the correlation analysis between the CCS and similar scales, a significant clear relationship was found. The CCS showed a positive correlation with scales such as opportunity inequality recognition, need for environmental change recognition, and social participation, and a negative correlation with the belief in a just world scale. Based on these results, the CCS can be considered valid and reliable. Finally, the limitations and significance of this study were discussed.

  • This article examines psychological factors that contribute to educational achievement of Korean adolescents. By reviewing empirical research, three core areas are outlined. First, positive and negative roles that Korean society play on academic achievement are analyzed. Compared to other countries, Korean society places a high premium, pressure an investment on educational achievement. This has contributed to the rapid economic growth and development, but at the same time it has created numerous social problems. Second, psychological and relational dynamics of investing in and achieving success in education are delineated. Through indigenous psychological analysis, the role parents play in motivating and regulating their children to succeed academically is reviewed. In addition, the role of teachers and friends and the coordinated efforts of Korean society are outlined. Third, future directions and transformations in education that are needed in Korean society are discussed. Although Korean adolescents are high achievers in high school, this is not the case at the university level. Since Korean students are interested in entering a prestigious university, they have developed skills in doing well in standardized tests. Educational reforms need to take into consideration individuals' personal interests, skills and creativity to ensure that the knowledge that they acquired can be used to further their career and improve their subjective well-being. Educational transformation does not imply simply adopting Western models, but developing indigenous models that can maximize human and cultural potential and stimulate curiosity, diversity and creativity that are necessary in the global era.

  • In the case of a patients who have lost the centric stop and have a staggered occlusion of the residual teeth, various movements occur when the denture is loaded. Implant placement is necessary to reinforce the retention, support, and stabilization elements to reduce denture movement. However, in this case, considering the patient's age, aversion to surgery, and bone loss, implants were not placed and restoration was performed with a removable partial denture. In this case, it is important to set the correct mandibular position for restoration because the patient has a habit of chewing with the remaining teeth. In this case, a stable mandibular position was established using a gothic arch tracing, and good results were obtained by restoring with partial dentures, so this is reported.

  • This study aims to understand students' perceptions of the spatial characteristics of school libraries when they use them for reading. We selected a set of spatial characteristics by reviewing the literature and conducting a preliminary investigation. Then, we examined how students perceived the importance of and how satisfied they were with each characteristic. In addition, we investigated how students' perceptions differ by the library uses and reading-related activities. We also studied whether the satisfaction of school library users affects their continued use of the libraries. We also verified whether school library user satisfaction is an intervening variable in continued-use intention, which is affected by spatial characteristics perception. We conducted a survey of 342 students from four middle schools. The analysis of the survey outcomes shows differences in library use due to spatial characteristics such as convenience, communicability, diversity, and safety. Factors such as communicability, comfortability, and ambience affected user satisfaction positively. Both aesthetics and communicability also positively influenced the continued-use intention. Furthermore, we identified that communicability, comfortability, and ambience eventually impacted the continued-use intention via user satisfaction, an intervening variable. The significance of this study is that it considered the direction of the school library to support students' reading by regarding the school library as a space for reading.

  • Nowadays, the increasing number of religious travelers seeking inner healing has led to the popularity of Buddhist 'temple stays', Protestant and Catholic 'retreats' as alternative vacations. However, unlike Buddhist temples, which are inculturated, Christian retreat centers follow the formula of general recreational facilities and lack an overall framework due to relying on sponsorship. This study attempts to design appropriate outdoor environments for a retreat by reflecting 'theological aesthetics' based on the process of 'Spiritual Exercises', the main method of retreat. First, as the Spiritual Exercises are often described as an 'inner pilgrimage', the images and theological aesthetics experienced in prayer themes were examined. Next, the characteristics of the spaces required for the facility were analyzed, and the composition of religious spaces was proposed. Also the landscape resources of the site were investigated, and the retreatants' behavior to derive spatial preferences was analyzed. Overall, outdoor spaces were planned to induce a shift in consciousness and broaden the spectrum of the retreatants' experience through a physical environment consistent with the mechanism of prayer. This study aimed to implement theological aesthetics by selecting a retreat center with high potential for landscape resources. As a result, it was possible to reveal the 'poetic landscape' to effectively evoke images during 'contemplative prayer', and to support religious experience. The significance of this study lied in deriving various design vocabularies for outdoor spaces of religious facilities.

  • The International Association Marine Aids to Navigation and Lighthouse Authorities (IALA) proposed guidelines for VTS manual operation in 2016 for safe and efficient operation of ship. The Korea Coast Guard (KCG) established and operated 19 VTS centers in ports and coastal waters across the country by 2022 based on the IALA VTS manual and VTS operator's education and training guidelines. In addition, IALA proposed the Inter-VTS Exchange Format (IVEF) Service recommendation (V-145), a standard for data exchange between VTS, in 2011 for efficient e-Navigation system services and safe and efficient VTS service support by VTS authorities. The IVEF service in a common framework for ship information exchange, and it presents seven basic IVEF service (BISs) models. VTS service providers can provide safer and more efficient VTS services by sharing VTS information on joint area using IVEF standards. Based on the BIS data, interaction, and interfacing models, this paper introduced the development of the cloud-based VTS integration services performed by the KCG and the results of the VTS integration platform test-bed for IVEF service implementation. In addition, the results of establishing a cloud VTS integrated platform test-bed for the implementation of IVEF service and implementing the main functions of IVEF service were presented.

  • The introduction of Smart technologies such as Artificial Intelligence(AI) systems are have a powerful impact in a variety of industry fields. Some experts predict that smart technology will completely change people's daily life and work styles, causing technological innovation, productivity improvement, and discovery and emergence of new fields. On the one hand, this vision cannot ignore negative views and concerns. Despite many social debates about employment, such as job loss and rising unemployment, there have not been many studies based on employee experience that provide a fundamental solution to the conflict between AI and employment. Therefore, this study finds out the effects and related factors of AI concierge robots for hotel employees, focusing on the hotel industry, and how employees' perceptions of AI concierge robots affect user resistance and turnover intention. This study, conducted a questionnaire survey of 322 hotel employees who had experience working with AI concierge robots in China, and used SPSS and SmartPLS statistical analysis programs to draw conclusions. We found that hotel employees' perceptions of AI concierge robots were significantly related to user resistance and turnover intention, and this association was related to employee self-efficacy, perceived organizational support, quality of AI services and new tasks. In addition, it was found that the quality of AI concierge robots directly or indirectly had the greatest influence on user resistance and turnover intention. The findings of this study provide theoretical implications for academia and practical implications for industry practitioners.

  • This study utilizes system dynamics to examine the effects of fine dust reduction policies on PM10 concentration and health. System dynamics has the advantage of modeling the dynamic and circular relationship between PM10 emission sources, reduction policies, PM10 concentration, and health effect. The study created policy scenarios for Korea's representative fine dust reduction policies - industrial PM10 emission control, diesel vehicle regulation, expansion of electric vehicles, and expansion of parks and green areas - and compared the results with the 2030 baseline if the current trend is maintained. The analysis showed that the policy of supporting electric vehicles reduced PM10 concentration by 0.21 ㎍/m3 and reduced the number of people with circulatory diseases by 494, and the effect was evenly distributed across the country. The industrial emissions regulation scenario resulted in the highest PM10 concentration reduction of 0.22 ㎍/m3, but had a lower reduction in the number of people affected (358) than the EV support strategy, which could be attributed to the fact that this policy had a particularly high PM10 reduction effect in industrial areas such as Danyang-gun, Chungcheongbuk-do, and Sahagu, Busan. As a policy implication, this study suggests that it is necessary to apply fine dust policies tailored to the characteristics of local emission sources.

  • The purpose of this study is to develop and verify the Relational Self Scale(RSS). Based on the theoretical assumptions which relational self is multi-dimensional and constructed in social contexts, 10 categories with 102 items were yielded. In the process of content analysis, item analysis, exploratory factor analysis and correlation analysis by administering 102 items to korean adults, 31 items with 7 factors are extracted. The 7 factors are consisted of 'avoidance of relation', 'consciousness of others', 'agency', 'instrumental relation', 'empathy-care', 'perceived support from relation' and 'over-dependency to relation'. Next, Confirmatory factor analysis was conducted with 649 korean adults aged from 20's to 60's. The results of confirmatory factor analysis showed the RSS as a valid scale. The 7 factors of the RSS fitted well with men and women. The internal consistency of the RSS was proved to be acceptable. The latent mean analysis indicated that the relational self was not significantly different between men and women at 7 factors. Correlation analysis showed that the construct of relational self was significantly related to relational self-construal, self-esteem and attachment to parent and intimacy person. This study has implication in that relational self is defined and assessed as multi-dimensional construct, and that by administering RSS it is possible to evaluate distinctive korean people's relational self.
