  • We examine the extent to which students' performance relative to peers affects their career choice. Specifically, we analyze the relationship between a student's mathematics ranking in his/her school and the likelihood of choosing Mathematics and Science track in high school. Using a panel dataset of students in Seoul, we measure a student's performance using two variables: absolute performance and relative performance. The former measures a student's performance relative to the entire sample, while the latter measures performance relative to the student's peers in the same school. After controlling for test scores and other characteristics, we find that the students with a poor relative ranking are 11 percentage points less likely to choose the Mathematics and Science track. Relative performance affects girls more greatly than boys. Although relative performance affects a student's self-efficacy and class participation, our accounting exercise suggests that this channel accounts for only 12 percent of the impact, implying that students may respond to the relative ranking mostly due to other factors, such as strategic consideration to perform well in college applications.

  • The interaction between users and games is an important factor in game development. In this paper, we consider Leaderboard UI in shooting game and study user's performance level according to presence or frequency of providing Leaderboard UI. For this research, we developed a third person shooting game and conducted experiments for 80 college students. The results of the experiments were analyzed using statistical significance using the T-test method. Finally, in order to improve user's performance level, we conclude that the user's gaming experience is a bigger factor than the presence or frequency of providing Leaderboard, causing a significant difference.

  • The shift to the digital media era is increasing the importance of the ability to accept, produce and share news through digital media(news literacy), but there is a lack of diagnosis of the level of news literacy among Korean adults and discussions on how to improve news literacy. This study analyzed the news literacy level of Korean adults according to background variables (urbanization degree, gender, age, academic background) and examined the relationship between the amount of news literacy-related practices and the level of news literacy. The results showed that the overall level of news literacy among adults in Korea was not high and that differences between groups were also statistically significant. The significant relevance between the amount of news literacy-related practices and the level of news literacy has also been identified. Based on the findings, it was suggested that the need for policy support to improve news literacy among Korean adults, the need to prioritize the resources of news literacy education according to background variables of adult learners, and the need to continuously monitor news literacy levels of Korean adults.

  • The chemical composition and content of essential oils extracted by ASTM standard D 889-93 method from the leaves of thirty introduced varieties in Perilla frutescens Britton var. japonica $H_{ARA}$ was investigated and compared. The oil was analysed by gas chromatography. More than forty compounds were found and thirteen compounds were identified. The major three constituents representing about $56{\sim}88%$ of total oil were shown caryophyllene and 2 unknown oils in 25 varieties. The chemical composition and content had much differences in each of varieties. This result seemed to be corresponding to introduce that varieties had diverse essential oils.
