This study summarizes the research methods, subjects, research processes, and achievements of major researchers by analyzing previous research results on Korean food history. The goal of the current study aimed to seek the methodology and direction of 'food history research'. Literature data from 1945 to 2022 were examined. Results of excavation research on ancient food literature were divided into the following stages: the 1980s, when the foundation for 'cataloging' was laid, and the 2000s, when 'digitization' was achieved. Achievements of each period were collected, and the achievements and limitations were analyzed. Next, the research results were classified into 'Food technology history', 'Recipe change history', and 'Food culture and dietary history'. We observed that around the 2000s, anthropology and folklore research perspectives were reflected, and the research on 'history of diet' reached a turning point. Our results indicate the possibility that food history can develop as a special historical area. This could be achieved by establishing an exchange system with other disciplines and creating a systematic curriculum.

Branded service encounters, in which various aspects of frontline employees are strategically aligned with the firm's brand positioning, can be achieved along several dimensions such as employee appearance, manner, and personality. While previous research has mainly focused on behavioral traits of employees, this research examines the employee's physical appearance in association with the brand personality trait across two studies. Study 1 shows that salesperson look-brand personality congruence enhances brand affect by inducing positive affect. Specifically, a brand-congruent look of a salesperson increases positive affect among customers by confirming their prior expectations about what a salesperson of a certain brand should look like as a brand representative. Study 2 reveals that the positive impact of salesperson look-brand personality congruence on brand affect is significant only for customers with high social anxiety whereas this effect disappears for those with low social anxiety. These findings extend previous research on branded service encounters by showing why and when frontline employees' physical appearance shapes customers' affective responses toward the brand.

Advanced countries have mandated applying BIM in construction projects. Also, Public Procurement Service has planned to mandate applying BIM to all construction project that ordered in PPS from 2016 in KOREA. However, now Seumter that is building administration system is not supported BIM based construction license BIM information from Seumter. Thus, despite the applicant is preparing a BIM model, they do not take advantage of BIM information in Seumter. In previous studies. We developed a BIM based building approval submission system. In this study, we verified the system that developed in previous research. As a result, requirement information input time reduction in Seumter system showed high satisfaction. But there was as low usability because building approval submission system cannot support some information for building approval in seumter. If the system will do utilization and management with the building approval system, the applicant can be using BIM base design document information and saving the time that takes at building approval submission. Study about the system improvement is required for application to building approval system.

This paper introduces an approach to enhance the performance of magnetic manipulation systems for microrobot actuation. A variety of eight-electromagnet configurations have been proposed to date. The previous study revealed that achieving 5 degrees of freedom (5-DOF) control necessitates at least eight electromagnets without encountering workspace singularities. But so far, the research considering the influence of iron cores embedded in electromagnets has not been conducted. This paper offers a novel approach to optimizing electromagnet configurations that effectively consider the influence of iron cores. The proposed methodology integrates probabilistic optimization with finite element methods (FEM), using Bayesian Optimization (BO). The Bayesian optimization aims to optimize the worst-case magnetic force generation for enhancing the performance of magnetic manipulation system. The proposed simulation-based model achieves approximately 20% improvement compared to previous systems in terms of actuation performance. This study has the potential for enhancing magnetic manipulation systems for microrobot control, particularly in medical and microscale technology applications.

In a previous study, the suitability for use of inspection equipment was evaluated at temperatures outside the quality assurance range. The quality assurance operating temperature of the safeguards equipment is 0~+40℃, and previous studies have confirmed the performance of the safeguards equipment for temperatures ranging from -40~+70℃. The scintillator-based verification equipment showed a shift in the centroid channel and a change in the count rate in all temperature ranges, and the semiconductor-based safeguards equipment generated Leakage Current and equipment failure. In this study, a retrofit was performed applying a vacuum housing to the safeguards equipment (Inspector-2000-based inspection equipment), and performance evaluation was performed at a low temperature and snowy site, and it was confirmed that the same performance was observed as the measurement results at room temperature.

The purpose of this study is to suggest a revised model for library e-service quality research based on Zeithaml & Bitner's model. To achieve this purpose, this study reviews the previous literature related to the study of service quality and e-service. According to the study results, 'physical quality' is the most important factor which influences on the customer perceptions of library e-service quality. Furthermore, this study suggests eight service quality dimensions of 'physical quality' for library e-service. In addition, customer's personal factors and previous experiences with similar services can be regarded as important factors which influence on the 'physical quality' of library e-service.

Due to the low conversion rate of social commerce, its sustainability is questioned. To solve this problem, this study aims to verify the different antecedents between visit intention and purchase intention. For a visit intention, this study employs the concept of the scarcity heuristic and its momentary characteristic. The scarcity heuristic is created by a scarcity of time and quantity, and provisional coupons. In previous studies, the scarcity heuristic has often been treated as a major factor in which to influence purchase intention. However, this study examines the scarcity heuristic only as an antecedent of the visit intention, not of the purchase intention, because of its momentary characteristic. Contrary to previous studies, as this study expected, the attributes of the scarcity heuristic had a significant relationship only with the visit intention in social commerce. Additionally, the results suggest that there are two distinct intentions in social commerce: visit intention and purchase intention. This study verified that the antecedents of the two distinct intentions are different from one another. This study helps to understand why people visit social commerce sites regularly but do not buy.

The COVID-19 pandemic has brought about many changes in our daily lives and in industries as a whole. The most notable change was the spread of the untact culture to minimize face-to-face contact. The spread of the untact culture has changed the use of public transportation. Looking at the results of previous SARS and MERS studies, it was found that as the pandemic spreads, the use of public transportation decreased. Recently, the mobility sharing service is attracting attention as a personalized means of transportation instead of public transportation. Therefore, in this study, the factors affecting the intention to use the mobility sharing service were to be identified by the actual users. In this study, economic benefit, convenience, sustainability, and sense of belonging were set as independent variables based on previous studies. In addition, the relationship between the perceived usefulness and perceived pleasure of these factors of use on intention to use was empirically analyzed through PLS-SEM. As a result of the study, it was found that economic benefits, convenience, sustainability, and sense of belongingness had a significant effect on intention to use through perceived usefulness and enjoyment. This study was meaningful in that it was verified through the study that economic benefits, convenience, sustainability, and a sense of belongingness were significant variables affecting the intention to use through usefulness and pleasure.

Purpose - This study reviewed domestic empirical studies on abusive supervision published from 2009 to 2020 and summarized the accumulated results. In particular, this study classified previous studies on abusive supervision as antecedents (supervisor characteristics, subordinate characteristics, and contextual factors) and outcome variables (cognition/awareness, affection/emotion, attitude, behavior, and others). Based on the results, this study suggested potential issues of previous studies and future directions for abusive supervision. In addition, this study proposed the academic and practical implications and limitations. Design/methodology/approach - The domestic studies on abusive supervision can be divided into antecedents and outcome variables, and each study was organized into the characteristics of the supervisor, subordinate, and situational characteristics, and the resultant variables were divided into cognition/awareness, affection/emotion, attitude, behavior, and others. Finding - Prior studies on abusive supervision had several limitations in obtaining clear results with individual characteristics or fragmented approaches at the organizational level. In the future, more comprehensive approaches will be needed. Research implications or Originality - This study will provide academic and practical implications for future research on abusive supervision by deepening an understanding of the negative consequences of abusive supervision.
