In this article, we address this shortcoming by exploring the concept of AI-based sustainable service—an offering that embeds artificial intelligence in ways that meet the needs of current consumers by contributing to socio-economic equalities and conserving the natural environment.

The present study compared the effectiveness of virtual influencers (VIs) to human influencers through the theoretical lens of the uncanny valley and parasocial relationship using an online experiment. Specifically, we posited that highly humanlike VIs may evoke the feeling of the uncanny valley, as compared to human influencers or cartoonlike influencers, which, in turn, would act as a psychological barrier to building a parasocial relationship with the specific type of virtual influencer and decrease advertising attitude. The results indicated that people do feel the uncanniness from both highly humanlike and cartoonish influencers as compared to human influencers. This particular psychological experience negatively influenced the parasocial relationship, which, in turn, negatively affected the attitude toward a social media advertisement featuring the VIs. However, importantly, this effect was moderated by individual differences in anthropomorphism. This is one of the first studies that directly compared the effectiveness of different types of social media influencers in a rigorously designed experimental setting and expands the previous research on Vis, uncanny valley, and parasocial relationship. Both theoretical and managerial contributions of the study were discussed.

Sustainability issue has received growing attention from various stakeholders. To engage more people to participate in sustainable actions, the United Nations has promoted #actnow campaign since 2019. Among various sustainability initiatives and approaches, the UN’s #actnow campaign focuses on food and fashion sustainability since these two industries encompass various sustainability issues from production and post-consumption. By analyzing Twitter's big data, the study findings demonstrate that negative sentiment messages are powerful in driving the public’s engagement in social media message dissemination. The findings suggest that practitioners may use assertive and strong voice messages to lead consumers’ participation in sustainable message dissemination.

B2B marketers increasingly encounter a pressure to be digitally present in digital channels and to generate content that is tempting in driving potential customers to interact with the company online (Wiersema, 2013; Andersson & Wikström 2017). This is what B2B lead nurturing is about as the objective of lead nurturing is to provide the audience with relevant and valuable content which leads to an increased brand interest and awareness, with the goal of bringing in new customers (Marketo, 2023). To better understand how prospects and leads react to digital content, companies can build lead scoring into a strategic tool for the salespeople to qualify the prospective customers down to a list of leads, meaning prospects who are considered the most likely to convert to a positive business outcome and to be contacted in person by the salespeople (Järvinen & Taiminen 2016; Paschen et al. 2020).

Existing studies report that social media influencers’ number of followers is a determinant of their influence. However, not every consumer follows an influencer with a high number of followers. Therefore, differences in individual characteristics should be considered in the effectiveness of influencer marketing. This study draws on the cultural dimensional theory to examine the moderating role of consumers’ cultural values at the individual level in the effects of social media influencers with many followers. The results show that the relationship between social media influencer follower count and brand reputation depends on the cultural values of individual consumers. This study makes certain contributtions to the advancement of research on influencer marketing and cultural values by identifying the different impact of follower account of social media influencers with many influencers.

This study aims to understand the influence of authentic marketing on the formation of trust between brands and customers and consumers’ purchase intentions and to analyze the role that brand trust has in this process. In doing so, it examines the specific aspects of authentic marketing that increase brand trust and contribute to the formation of purchase intentions, which could then be leveraged as key elements of a company’s marketing strategy. Data in this study was used frequency analysis and factor analysis through SPSS 26.0, and reliability analysis using Cronbach’s alpha coefficient. Subsequently, confirmatory factor analysis, path model analysis, and mediated effect analysis were performed using AMOS. Finding indicate that, identity and truth in authentic marketing had a positive effect on brand trust but heritage and reality did not affect brand trust. It was also found that the factors of identity, heritage, reality, and trust did not significantly affect purchase intention. Additionally, brand trust was found to have a positive effect on purchase intention. Finally, the analysis indicates that brand trust plays a mediating role in the process of forming purchase intention through the factors of identity and truth in authentic marketing. Therefore, the core of authentic marketing is the sincere relationship between companies and consumers obtained from the clarity and integrity of messages, and in this process, mutual trust is built, which leads to product purchases. It can be surmised that the purpose of authentic marketing is to build relationships with consumers based on brand trust.

Construction industry is considered as one of the most high-risk industries for work-related injuries and fatalities, accounting for more than half of fatalities in Korea. Advanced countries have recognized the critical role of designers in preventing construction accidents and have established regulations on design for safety. In line with this, the Korean government have also implemented regulations that require owners and designers to review the safety of design outcomes. However, it has been observed that designers face challenges in identifying hazards and integrating design solutions at the design stage mainly due to their shortage of required knowledge and skills. This study aimed to examine design solutions that can be applied to prevent fall accidents in the construction industry, and to establish a relationship between these solutions and fatal fall accidents occurred over the past three years in Korea. This study also analyzed the relationships of four variables (construction type, cost, work type, and fall location) with design solutions. The results indicated that all four variables have significant relationships with design solutions, with fall location showing the strongest relationship. The design solutions and their relationships with fatal fall accidents identified in this study can be utilized in identifying hazard and integrating design solutions to ensure design for safety.

Zinc injection into the coolant system of nuclear power plants is an effective method for reducing corrosion and improving performance. The effectiveness of this method is influenced by various factors such as zinc concentration and injection rate. This paper provides an overview of the factors affecting the effectiveness of zinc injection in nuclear power plants, with a focus on zinc concentration and injection rate, and discusses various research results on the effects of these factors on corrosion reduction and coolant system performance. Zinc concentration is an important factor affecting the effectiveness of zinc injection. The research results show that gradual increases in zinc concentration are more effective for coolant system stability. However, the concentration should not exceed the recommended levels as high zinc concentrations can have negative effects on the system. Injection rate is also an important factor affecting the effectiveness of this method. The research results show that gradual increases in injection rate are more effective for coolant system stability. However, excessive injection rates can have negative effects on the system such as overload of the zinc injection facility and chemical shocks within the coolant system, and therefore, should be optimized. In conclusion, zinc concentration and injection rate are important factors affecting the effectiveness of zinc injection in nuclear power plants. The optimal concentration and injection rate should be determined based on specific reactor conditions and system requirements, and efforts should be made to maximize corrosion reduction and performance improvement.

With the introduction and implementation of the National Research and Development Innovation Act in 2021, researchers are required to have a greater understanding of research ethics and to comply more strictly. The range of misconduct in research and the standards for sanctions have been expanded with the introduction of the National Research and Development Innovation Act. In addition, researchperforming institutions and specialized agencies have been obligated to establish their own research management systems and standards according to the changed criteria. The Korea Institute of Nuclear Nonproliferation and Control (KINAC), a nuclear regulatory authority that is conducting national R&D in related fields, has sought to strengthen research ethics by revising related regulations, introducing a plagiarism detection system, and expanding related education in accordance with these policies. In this study, we analyzed the effectiveness of the plagiarism detection system as a basic quality control measure for research results and a tool for enhancing research ethics, which was introduced. KINAC did not simply introduce a plagiarism detection program but established institutional improvements and other regulatory measures to support it, with the aim of more effectively managing research results. To analyze the effectiveness of this system, we calculated the plagiarism rate by sampling 30 papers each year for the three years before the introduction of the plagiarism detection system. When comparing the plagiarism rates before and after the introduction of the plagiarism detection system, no exceptional cases of high plagiarism rates were found in papers published after the introduction of the system. Although most of the papers before the introduction of the system showed a satisfactory plagiarism rate, some cases showed high plagiarism rates. We analyzed the cause of such cases in detail. Some exceptional cases were also found to be included in the range of misconduct regulated by the National Research and Development Innovation Act. As no such cases were found after the introduction of the system, we could infer that the system is effectively functioning as a tool for basic quality control and enhancing research ethics. In the future, we plan to expand the sample qualitatively and quantitatively by including other forms of outcomes published by the institution, not just papers, and conduct a more detailed analysis. Based on the results, we will develop various improvement plans for enhancing the quality and research ethics of the institution’s research results.

The purpose of the study was to analyze effectiveness of Korea’s bilateral development cooperation for the agricultural sector in Myanmar using secondary time-series data from 1991 and 2018. This study utilized the Vector Error Correction Model (VECM). Results showed that Korea’s bilateral development cooperation in the agricultural sector had a positive effect on the agricultural GDP in Myanmar with a significant contribution. This study suggests that the Myanmar government needs to use ODA (Official Development Assistance) for efficient and sustainable agriculture in a more timely and manageable manner. Although the agricultural sector in Myanmar has great potential for development, there are various weaknesses such as the lack of access to foreign aid compared to other ASEAN countries due to the lack of stability in policy legislation. If it formulates better agricultural policies, laws, and legislation, there would be more support from Korea and other partner countries than ever before.

Background: This study was carried out to determine whether non-face-to-face physical therapy would have similar exercise effects to face-to-face physical therapy. Hence, we developed an approach for patients, unable to visit hospitals due to circumstances such as the COVID-19 pandemic, to conduct physical therapy comfortably at home. Objects: This study aimed to compare the effects of a face-to-face and a non-face-to-face physical therapy treatment on improving a rounded shoulder posture. Methods: The participants with rounded shoulders were randomly divided into a face-toface group (n = 15) and a non-face-to-face group (n = 15), and each group performed exercises for four weeks. The exercise program consisted of the bare hands exercise, Thera-Band exercise, and foam roller exercise. The participants in the face-to-face group came to a designated place to perform their exercises, and those in the non-face-to-face group performed the exercises at their own home using Google Meet (Google). Acromial height, total scapular distance (TSD), shoulder pain and dysfunction index (SPADI), and pectoralis minor thickness were measured. Data analysis was performed using the R Statistical Software (R Core Team), and a normality test was performed using the Shapiro-Wilk test. Results: There were no significant differences between the face-to-face and the non-face-toface groups (p > 0.05). When comparing the differences before and after the exercises, both the face-to-face and the non-face-to-face groups showed significant differences in acromial height, SPADI, and pectoralis minor thickness (p < 0.05), and both groups showed no significant difference in TSD before and after the exercises (p > 0.05). Conclusion: The results of this study support the results of previous studies reporting that shoulder stabilization exercise and pectoralis minor stretching training improves round shoulders. In addition, this study revealed that both the face-to-face and the non-face-to-face physical therapy treatments had therapeutic effects.

PURPOSES : The purpose of this study is to evaluate the effectiveness of self-luminescent road markings using driving simulation. METHODS : In this study, a driving simulation was conducted to evaluate the effectiveness of self-luminescent road markings. The details of this study are as follows. Highway sections were categorized as tunnels, tunnel approaches, bridges, merging areas, mainlines, and curbs. The luminance of the existing road markings was collected through field measurements. The luminance of the self-luminescent road markings was collected through experimental measurements. The luminance of the road markings is converted into a brightness ratio to be applied to the driving simulation. Road facilities at night were visualized during the driving simulation. Driving simulation was tested by 30 participants. Each participant rated the visibility perception of both the road markings ahead of 90 m with a 5-point scale. The log data generated from the driving simulation tests were analyzed. RESULTS : The luminance of the existing road markings and self-luminescent road markings was measured. The luminance of the existing and lab-based road markings was converted into a brightness ratio. The road facilities of highway sections were investigated for driving simulations. The driving simulation was tested by 30 participants. Visibility perception ratings and log data from the driving simulation were analyzed. The average of visibility point increased from 1.01 to 4.63 when self-luminescent road markings were added to the existing road markings. The average speed also increased when self-luminescent road markings were added to existing road markings. CONCLUSIONS : In conclusion, self-luminescent road markings can improve the visibility of road markings and driving speed, particularly in highway sections where driving speed decreases owing to low visibility.

Most of the steam turbine control valves used for the fossil and nuclear power plants operation in South Korea were developed by GE (General Electric) and manufactured by DHIC (Doosan Heavy Industry Company). For may years, DHIC have tried to develop their own technologies related to the power generation. DHIC has launched many R&D projects and ‘Development of a Control Valve Flow Code for Steam Turbine Operation Control of Fossil Power Plant’ was one of the R&D projects. Through our project, we accomplished the experimental method to obtain a steam turbine control valve characteristic curve using the atmospheric air and the reduced model instead using the steam and the real model. Also, we developed the correction method to calculate the real steam mass flow rate from the characteristic curve obtain by the experiment. In this paper, the effectiveness of the correction method was reviewed and it was concluded that the corrected mass flow rate complies well with the real steam mass flow rate.
