The purpose of this study is to examine the probabilities and expenditures of game users' loot box purchases and to verify if there are differential effects on adults and teenagers. Results show that the purchasing probability of teenagers was significantly lower than that of adults, and the amount was also low or not significant. In addition, loot box purchasing has a positive correlation with the total expenditure on games, but teenage buyers have a lower game spending than adults do. This suggests the possibility that loot boxes are considered as cost-saving products for teenage gamers.

This study analyzed the self-identified cold tolerance and wearing behavior of teenagers inside and outside the classroom during winter, considering recent climate changes. A questionnaire was divided into four parts-general information, thermal and comfort sensation inside and outside classroom, self-identified cold tolerance, and wearing behavior to collect data from 322 students. Over several years, changes were noted in respondents' wearing behavior during winter outings, with the biggest being the purchase of a "long padded jacket" for warmth while outside. Most respondents showed similar wearing behavior, such as no difference between the number of clothes worn in a classroom maintained at 20℃ (girls: 8.0±3.1 layer, boys: 6.5±2.1 layer) and outside (girls: 8.8±3.4 layer, boys: 7.1±3.0 layer), despite feeling differently about the thermal sensation inside and outside the classroom. This difference may due to a teenager's lack of knowledge about temperature and their tendency to follow clothing trends. Female students were more sensitive to the cold and wore more garments inside and outside the classroom. Gender-related differences should be considered when educating teenagers about safe and healthy clothing.
