Social media has dominated the online world in recent years. With this comes the question of whether social media use may lead to social comparison, and consequently, lower self-esteem. Kintsugi has come to answer this question by defining what self-representation on social media is, pinpointing its impact on the younger generations, and proposing some possible solutions.

In the past 20 years, the Internet and social networks have grown and attracted the attention of the young generation. The current situation of internet usage among Vietnamese young people today is very popular. The two most outstanding challenges are health and social life. The health challenges include physical and mental health, while the social life challenges focus on social relationships, cognitive development, and the safety of young people. Young people's adaptation to these influences is divided into two main ideas: awareness and actions. The right perception of harm leads to practical action. In terms of physical health, we suggest eating, exercising or taking care of skin according to videos on the internet. In terms of mental health, finding new hobbies and setting up a reasonable schedule are the two examples. In terms of social relationship, we highly recommend participating in extracurricular activities, in terms of the development of awareness, we should read reputable sources instead of unofficial ones, the Ministry of Information and Communication must control the content on social networks. In terms of safety, users spread good knowledge and protect personal security. Researching the impact of the cyber world on young generation in Viet Nam is extremely necessary. The research becomes more and more crucial in the age of international integration, in which young people need to understand how to protect themselves from the negative sides of the cyber world.

Carbon monoxide, the second-highest pollutant gas in the world after carbon dioxide, is a major pollution produced from the human-made machines or factories. This gas could be the air quality index as the higher carbon monoxide density, the worse air quality. The urban neighborhood’s cumulative carbon monoxide density is more than the others and has been a hazardous issue. The gas detection station is limited to detect gas in downwind areas and the overall image is not widely monitored, by that difficulty, this project adapted Sentinel-5P satellite to study carbon monoxide in the study area, Bangkok, for further modeling in the study of atmospheric pollutants in Thailand. TROPOMI sensors, attached to the satellite, could detect gas density by characteristic electromagnetic wave reflection of each gas. This project got accessed to satellite data by using Javascript in the Google Earth Engine Code Editor environment. The study perceived that carbon monoxide over Bangkok has its seasonal pattern in which the gas is inclined to undergo the highest density in the winter and lowest in the summer. From analyzing the meteorological variables derived from ERAS, the research team appraised that the surface pressure and west-to-east surface wind velocity were moderately and low correlated with carbon monoxide density in terms of Pearson correlation coefficient. Finally, the researchers collected gas density data above the Phayathai station to quantify tomorrow's computed gas prediction model in the linear multiple regression equation formation. The completed model presented a 0.00437 error value.

Online communities have grown at unprecedented rates in the past decade. Due to the COVID-19 pandemic, many people have sought out interactions in these online spaces and have started to build a community around them. Currently, there is no study examining the aspects of community building within online communities. Thus, this study examined the community building aspect of a Facebook group centered around the discovery and discussion of food. Specifically, this study discovered the kinds of topics being discussed in posts within these online communities, the factors that drive quality interaction within these posts, and the extent community building can be found in these communities, specifically in the food discourse that occurs within it. Using the community building framework adapted from Brown (2001), 2891 comments within 19 posts were examined using corpus analysis. Results show that most online interactions are short and tend to be with people they already know in real life. It is the people who post and share their food discoveries and experiences that keep these communities active. Interactions with online strangers centered around common interests. The results of the study may give insights on how to better structure online communities to encourage more meaningful interactions and foster a greater sense of online community. A similar approach to other online communities (political, academic, fandoms, interest-based, etc.) and other platforms (Reddit, Tumblr, etc.) may be investigated for a more comprehensive theory on online communities.
