Recently, the boundaries between people who produce and consume digital contents disappears due to the massive developments in information and communications technology (ICT) and the rapidly increasing spread of smartphones unlike in the traditional mass media (e.g., newspapers, radios, and TVs). Through the open service platform, the problem perception for each individual remains the same, but the problem solving methods varies as the service types have been diversified. The creation of added value through the growth of the new media platform industry is expected to enrich our lives, but it can also cause severe social side effects. For example, communication problems between social classes due to the information gap have led to generational conflict, and if such problems persist, it can cause national and social losses. Therefore, this paper analyzes the policy efforts to resolve the information gap and the necessity of the legalization of multimedia literary education to maximize the synergy effect through psychological model.

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.

Virtual humans are implemented with dedicated modeling tools like Unity 3D Engine in virtual space (virtual reality, mixed reality, metaverse, etc.). Various human modeling tools have been introduced to implement virtual human-like appearance, voice, expression, and behavior similar to real people, and virtual humans implemented via these tools can communicate with users to some extent. However, most of the virtual humans so far have stayed unimodal using only text or speech. As AI technologies advance, the outdated machine-centered dialogue system is now changing to a human-centered, natural multi-modal system. By using several pre-trained networks, we implemented an emotion-based multi-modal dialogue system, which generates human-like utterances and displays appropriate facial expressions in real-time.

Dental caries is a multifactorial disease influenced by interactions between teeth, biofilm, dietary factors, and various biological, behavioral, sociocultural, and genetic factors. Recent research has shown that dental caries results from dysbiosis, an imbalance in the oral microbial community, shifting the concept from an infectious disease to a non-communicable disease (NCD). Dental caries shares similarities with other chronic NCDs such as cardiovascular diseases and diabetes, as they all relate to dietary intake, lifestyle habits, and environmental factors. Considering the high prevalence of dental caries and its impact on people's health and quality of life, it is important to understand dental caries as an NCD and develop effective oral health management strategies. Ecological prevention methods and efficient public health policies should be provided to reduce risk factors associated with dental caries.

Gaze estimation, which automatically recognizes where a user is currently staring, and object detection based on estimated gaze point, can be a more accurate and efficient way to understand human visual behavior. in this paper, we propose a method to detect the objects within the region of interest around the gaze point. Specifically, after estimating the 3D gaze point, a region of interest based on the estimated gaze point is created to ensure that object detection occurs only within the region of interest. In our experiments, we compared the performance of general object detection, and the proposed object detection based on region of interest, and found that the processing time per frame was 1.4ms and 1.1ms, respectively, indicating that the proposed method was faster in terms of processing speed.

In this paper, we implement a learning efficiency verification system to inspire learning motivation and help improve concentration by detecting the situation of the user studying. To this aim, data on learning attitude and concentration are measured by extracting the movement of the user's face or body through a real-time camera. The Jetson board was used to implement the real-time embedded system, and a convolutional neural network (CNN) was implemented for image recognition. After detecting the feature part of the object using a CNN, motion detection is performed. The captured image is shown in a GUI written in PYQT5, and data is collected by sending push messages when each of the actions is obstructed. In addition, each function can be executed on the main screen made with the GUI, and functions such as a statistical graph that calculates the collected data, To do list, and white noise are performed. Through learning efficiency checking system, various functions including data collection and analysis of targets were provided to users.

This study examined the empathy relationship experiences of adolescents in relationships with school social workers. The researchers conducted individual interviews with 10 adolescents from low-SES families. The primary interview query was 'What have empathy relationship experiences with school social workers meant to you?' Interview responses were coded and the results were analyzed using phenomenological research methods. The empathy experiences of adolescents were identified as the following: 'tried to build empathy','understanding another's feelings', 'helpfulness'. The study's results summarized the adolescents' feelings of empathy resulting from their interactions with school social workers. In conclusion, the study suggested some useful strategies for school social workers in their work with adolescents from low-SES families. These strategies are designed to maximize adolescents' ability to feel empathy for others. Furthermore, based on the results of this study the researchers suggest some promising avenues for empathy research in various fields.

As people spend more time indoors due to the COVID-19 pandemic situation, content consumption is increasing, leading to the rapid demand for Over The Top(OTT) services. Thus, this study attempted to verify impacts of OTT traits on the value, satisfaction, and continuous use intention perceived by users. Through the survey, 437 responses were collected, and analysis was conducted using AMOS 26.0. Results found that the traits of OTT service had a positive effect on perceived value that had a positive effect on user satisfaction and continuous use intention. User satisfaction was also found to have a positive effect on the intention to continue using OTT services. Moreover, hedonic innovation moderated the relationships between OTT traits and perceived value with exception of ubiquity. The findings provide valuable information for OTT service providers in understading users' behaviors.

Covid-19 calls for minimizing gatherings of people in spaces such as offices. Organizations are encouraging information-sharing activities among employees by using online platform technology. Recently, Organizations are supporting their work using the metaverse. This study confirms the effect of metaverse presence on the intention to share knowledge by forming the intrinsic motivation of the employees and the moderating effect of the individual's digital technological competence. We presented research hypotheses through previous studies such as virtual reality and tested the hypotheses using 309 samples obtained through surveys. As a result, the social, tele, and self presence of the metaverse increased organizational-related intrinsic motivation(organizational identification, value congruence) and had a positive effect on the intention to share knowledge. In addition, digital technological competence moderated the relationship between value congruence and intention to share knowledge. This study suggests the importance of strategies to enhance the presence of metaverse for organizations to increase work productivity by using metaverse and the need to support individual digital competence reinforcement.

In this paper, we reviewed the community-based approaches to suicide prevention and national strategies for the decrement of suicide rate, and made some suggestions to decrease the suicide rate in South Korea. Until now, efforts to understand and prevent suicide have been pursued singularly by specialized interest groups such as psychiatrists, psychologists, mental health practitioners, and private organizations with little interaction between them, resulting in narrow approaches toward suicide that existed in relative isolation to one another and that have been largely ineffective. To decline the suicide rate in South Korea, the people lived in Korea community ought to have enough knowledge related to suicide and have to cooperate with other people. Through these efforts, Korea community would have established social safety networks to improve the community 's mental health. The most important factor in suicide prevention and declining the suicide rate is reducing the stigma and increase the self-help seeking behaviors associated with suicide and mental health. Therefore, suicide is not an individual problem solved by suicidal patient, but a community's problem solved by community in recognizing, managing and preventing suicide.
