The aim of this study was to investigate the psychological impact of colored classroom walls on individuals. The research was conducted with eighth-grade students from an international school in Chiang Mai, Thailand. A total of 34 students with a variety of cultural backgrounds participated in this study. Students attended their regular classes with the three wall colors of purple, green, and red, while the Bourdon Attention Test was utilized as an assessment of the students' attention level. Data from the two conditions, control and experimental groups, each consisting of both pre-test and post-test, were collected and examined to find out the effects of different wall colors on the student's attention. The results indicate that the classroom with red-colored walls showed a significant impact on the participant’s attention. In summary, this paper will contribute to enhancing awareness of how wall colors in educational facilities affect student’s learning activity as well as to assist future designer’s decisions on the usage of appropriate colors.

This research paper examines the training hours, physical appearances, and on-screen personalities as potential factors of success in today’s K-pop industry in an attempt to understand such global success. The top 10 most popular male K-pop groups were chosen as this paper’s samples based on the criteria of album sales and music video views. The research method of content analysis was employed to measure certain aspects of each factor; the total training hours, average facial scores based on rules of symmetry, and frequencies of introverted or extroverted behaviors were collected for each group. For the majority, groups that went through extensive training periods, had high facial symmetry scores, and leaned more toward introverted personalities on average were found to be among the most popular and successful. It is important to note, however, that the last outcome may have been due to South Korea’s societal expectations and culture.
