In an acceleration of 'untact' society during the COVID-19 pandemic, video conferencing platforms have been provided to connect the isolated and to overcome the limit of having interpersonal relationships. While these services brought a great deal of benefits, they also increased the number of people who suffer from additional fatigue from video conferencing. This study, thus, aimed to identify the factors of using video conferencing services and further to examine the relationship between the factors and the users' overall fatigue. Through focus-group interviews and survey, four main factors of fatigue (restriction from untact communication, difficulty of use, background set-ups, discomfort from excessive attention) were identified. This study also found the positive relationships of restriction from untact communication and background set-ups on the users' overall fatigue. The results does not only provide implication on defining new fatigue factors from young generations but also help practitioners and service providers to improve the deficits of services that the real users currently experience.

Social Networking Service (SNS) is a part of our daily lives, with their positive and negative impacts. This study investigates SNS fatigue in men and women of different cultural backgrounds as well as the relationship between SNS fatigue and the intentions to cease SNS activities. The study results show that during SNS activities, women are more concerned for their reputation; participants with East Asian cultural backgrounds experience burdens with respect to relationships, and participants with Western cultural backgrounds experience fatigue with respect to privacy concerns. No statistical significance was identified between SNS fatigue and the intentions to cease SNS activity; although people experienced fatigue, they did not desire to stop SNS use. This study reveals that culture and gender impacts SNS fatigue, and few people quit SNS despite the fatigue.

The aim of this study is to investigate the relationship between communication motive, fatigue and loneliness in mobile environment. According to previous research, the most important communication motive in mobile environment is pleasure. Therefore, pleasure was selected as a representative communication motive. To do this, we collected data for empirical analysis from mobile messenger users using questionnaire. We found that pleasure has a negative effect on loneliness. Second, pleasure has a negative effect on connection, function, and focus. On the other hand, pleasure has no effect on delivery and relationship fatigue. Finally, function and focus have a positive effect on loneliness. On the other hand, connection, delivery, and relationship fatigue have no effect on loneliness. As a result of the research, it is possible to reduce the function and focus fatigue due to the use of the mobile messenger by adding the functions that cause the enjoyment of using the messenger. In addition, the addition of fun-inducing features can also reduce loneliness caused by the use of mobile messenger. Future research will also need to identify factors that may reduce connection and relationship fatigue.

Continuous use of SNS with having SNS fatigue influences users mentally as well as physically. Although it is reported that they eventually leave SNS due to experience of fatigue, the determinants of SNS fatigue have not been discovered yet. Thus this study aims to find the psychological factors causing SNS fatigue. This study (1) found out the factors causing SNS fatigue, and (2) explored the relationships between the factors and intentions to discontinue/continue to use SNS. Findings of the study suggested that there are seven types of determinants: Sense of relative deprivation, Relationship concern, Management burden, Information overload, Privacy concern, Reputation concern(after posting), Reputation concern(before posting). It is also found that sense of relative deprivation negatively predicted the intention to keep using SNS while management burden, reputation concern(before posting) predicted positively. Furthermore, the sense of relative deprivation and information overload positively predicted the intention to discontinue using SNS while reputation concern(before posting) predicted negatively. This research examined how the determinants of SNS fatigue affect the intentions to keep/stop using SNS from the two different points of view. The determinants of SNS fatigue experienced by SNS viewers influenced them to have intentions to stop using it, whereas those felt by SNS writers affected them to keep using it.

산업의 발전과 함께 소비3자의 욕구는 제품의 질적, 감성적 향상을 요구하고 있으며, 또한 최근 각종 공학의 눈부신 발전에 힘입어서 자동차의 성능, 안락성 등이 크게 향상되면서 운전자의 운전 중 피로감 제거에 관심이 높아지고 있다. 본 연구는 주관적인 피로감 평가 방식 중 졸림감(KSS), 피로감 용어 및 신체 불편도를 이용하여 평가를 수행하였다. 졸림감 및 피로감 용어는 차종 및 자세에 따라 약간의 차이가 있었지만, 대체적으로 시간이 지남에 따라 불편함의 정도가 심해졌다. 신체 불편도에 대한 평가결과 엉덩이, 요추, 어때, 좌우 발목 부위가 불편한 것으로 나타났다. 이러한 결과들은 차종별 또는 운전자세에 따라 통계적으로 유의한 차이를 보이기도 했다. 이러한 연구 결과를 통해서 동환경 시스템의 기초 데이터를 확보할 뿐만 아니라, 자동차를 설계하는데 있어, 보다 안락하고 편안한 운전환경을 만들 수 있는 기초자료로써 활용이 가능할 것이다.

This study empirically studied the factors affecting the intensity of use of mobile social media and fatigue. Theories for the research framework were based on the theory of planned behavior, the theory of private information protection, the theory of flow, and the theory of process incentives. As a result of data analysis, it was found that self-efficacy, user habits, and flow experience positively influence the intensity of mobile social media use. This study assumed that personal information protection issues negatively affect the intensity of mobile social media use, but have little influence on the use intensity. The intensity of media use had a positive effect on media fatigue. In other words, when the intensity of using mobile social media increased, the feeling of fatigue increased. The expected process incentives variable did not show a moderating effect between media use intensity and social media fatigue. The findings will have implications for social media-related companies and organizations that want to use social media tools for business and public services.

Recently, SNS users have begun to complain of fatigue attributed by the dependency on the Social Networking Services, and this trend seem to have them cease or leave the SNS despite its exponential growth. Although researchers devote their effort to identify negative effects of perceived SNS fatigue on the intention to keep using SNS, it still lacks dealing with users' personal characteristics. Thus, this study looked into (1) the differences of perceived SNS fatigue and the differences of intention to leave SNS based on the users' characteristics (demographic variables, personality traits, and SNS usages) and (2) the users' characteristics on the intention to discontinue SNS. The results show that the users with low self-esteem were more likely to feel higher SNS fatigue and to discontinue SNS than those with high self-esteem, and the users in 20s showed higher intention to discontinue SNS than those in 40s. Moreover, the younger the users were, and the lower the levels of self-esteem were, the users reported higher level of fatigue. Additionally, the female users showed that the higher the level of fatigue, the stronger intentions to discontinue SNS. This research sheds light on the fact that the characteristics of users give influences the intention to discontinue SNS, and is expected to suggest practical implications in the ever-expanding SNS market.

The purpose of this study is to find the relation between the detailed categories of the self-efficacy of workers in the field of railroad signaling and the detailed categories of their fatigue in the use of analysis of moment structure(AMOS) model. A self-administered questionnaire survey of workers in the field of railroad signaling had been conducted and a total of 341 copies were analyzed. This study had the assumption that their general self-efficacy and social self-efficacy would negatively influence their physical fatigue and mental fatigue. As a result, their general self-efficacy negatively influenced their physical fatigue and mental fatigue, whereas their social self-efficacy didn't influence their physical fatigue and mental fatigue. Therefore, it is possible to reduce the fatigue of the study subjects by enhancing corporate support to increase their general self-efficacy.
