The use of social media has many advantages such as knowledge sharing, social networking, and communicating with other people. However, it has given rise to various side effects including stress, Which is defined as social network stress in this study. This study aims to conceptualize social network stress and investigate its effect on switching behavior in social media. For this purpose, we present a research model that consists of the antecedents and consequences of social network stress and test it empirically using LISREL 8.7 based on the structural equation model. The empirical results showed that knowledge sharing and self-disclosure had positive impact on social network stress, which in turn positively influenced social media switching behaviors. In conclusion, we discussed both theoretical and practical implications of this research and suggested its limitations.

The ethics of Daesoon Jinrihoe is a system of contemporary practical morality, which contains religious features such as "One Dao" (一道), "Two Mountains" (二山, an allusion to Kang Jeungsan 姜甑山, and Jo Jeongson 趙鼎山), "Three Realms" (三界, means the realms of Heaven, Earth, and Humanity." For the purpose of my paper, "One Dao" is the ethical principle of Daesoon as well as the Tenets: "the Virtuous Concordance of Yin and Yang, Harmonious Union between Divine and Human Beings, the Resolution of Grievances for Mutual Beneficence, and Perfected Unification (jingyeong 眞境) with the Dao." "Two Mountains" are the Objects of belief. The Three Realms are the scopes of moral concern. In order to devote the Tenets of the ethical principle, ascetic practice in daily life has been emphasized as "Sincerity, Respectfulness, and Faithfulness" which are collectively called "Three Essential Attitudes." Meanwhile, "Quieting the Mind, Quieting the Body, Reverence for Heaven, and Cultivation (of oneself in accordance with doctrines)" are defined as the "Four Cardinal Mottoes." The ultimate belief is converted into guidelines for ethical conduct and religious rites. Through cultivation an interaction emerges between humankind and divine beings. The ethical ideal in Daesoon Jinrihoe includes personal "Perfected Unification with the Dao," nobility and cooperativity between humans and divine beings, and "the earthly paradise of the Later World." Compared to Buddhism, Christianity, and Daoism, Daesoon Jinrihoe's unique features are embodies by three aspects: the unity of mutual beneficence among the Three Realms, the cooperativity and nobility between humans and divinities, and the transcendental nature of the earthly paradise.

Laser-induced plasmonic sintering of metal nanoparticles (NPs) is a promising technology to fabricate flexible conducting electrodes, since it provides instantaneous, simple, and scalable manufacturing strategies without requiring costly facilities and complex processes. However, the metal NPs are quite expensive because complicated synthesis procedures are needed to achieve long-term reliability with regard to chemical deterioration and NP aggregation. Herein, we report laser-induced Ag NP self-generation and sequential sintering process based on low-cost Ag organometallic material for demonstrating high-quality microelectrodes. Upon the irradiation of laser with 532 nm wavelength, pre-baked Ag organometallic film coated on a transparent polyimide substrate was transformed into a high-performance Ag conductor (resistivity of 2.2 × 10^-4 Ω·cm). To verify the practical usefulness of the technology, we successfully demonstrated a wearable transparent heater by using Ag-mesh transparent electrodes, which exhibited a high transmittance of 80% and low sheet resistance of 7 Ω/square.

This study aims to lead the new discussion by looking at variables affecting the number of subscription channels and subscription satisfaction in the absence of academic discussion of users' YouTube subscriptions. To this end, we conducted an online survey and analyzed the factors affecting the number of subscription channels and subscription satisfaction of YouTube users. We conducted hierarchical regression to examine their subscription motivation with exploratory factor analysis and to examine the impact of subscription motivations and the intentionality of Youtubers and the usefulness of YouTube knowledge on the number of subscription channels and subscription satisfaction. The analysis results are as follows: First, YouTube's usage and convenience motivation have had a static impact on the number of subscription channels. Second, factors affecting subscription satisfaction have been shown to be convenience subscription motivation, communication with Youtubers motivation, and perceived usefulness of YouTube. The practical significance of this work is that it can be beneficial to platform and channel operators in the changing new media environment. Furthermore, it aims to expand the interaction research extensions between YouTuber and users in the new media environment.

The object of this study is through an empirical analysis, how cultural capital at the individual level and social welfare expenditure at the national level affect the life satisfaction of the elderly. In this study method, a Hierarchical Linear Model(HLM) analysis was performed on 3,297 elderly people aged 65 and older and 9 OECD countries. As a result of analysis, first, it was confirmed that life satisfaction and social class had a significant effect. Therefore, in to increase the satisfaction of the life of the elderly, policy and practical intervention measures that can narrow the gap between social classes should be prepared. Second, the old-age pension and survivor's pension had no significant effect on life satisfaction. However, as a result of the interaction, social class has a positive effect on life satisfaction, and it was confirmed that the lower the income inequality, the more positive the life satisfaction was. In conclusion, this implies that both individuals and countries should make efforts to variously increase the life satisfaction of the elderly.

This study compares two cases in which flipped learning is applied in the active learning classroom (ALC) and fixed classroom of advanced engineering education. To this end, the difference in pre-learning, academic achievement, and class satisfaction between ALC and fixed classroom flipped learning were compared. The results revealed that students in ALC flipped learning watched more video lectures for pre-learning than those in the fixed classroom flipped learning and achieved higher scores on final tests, though they obtained lower points on midterm exam. In addition, examination of class satisfaction with questions about class factors, instructor factors, and overall satisfaction revealed that ALC flipped learning showed higher satisfaction in all factors than the fixed classroom flipped learning. This case study suggests that the ALC environment, a learning space built to facilitate learner-centered activities, is more effective for flipped learning that requires active interaction in the classroom.
