The effects of regular and active leisure activities on positive growth and development in adolescents are widely known. In our society, however, it is challenging to enjoy or expand such activities due to diverse constraints. Under unfavorable circumstances, this study attempted to investigate the application of time availability for liberal leisure activities as a way to help adolescents engage in active leisure activities. Specifically, this study examined the relationship between time availability (both individual and structural) and the time invested in leisure activities at youth training centers which support such leisure activities. The study found the following results: As both individual and structural time availability expanded, the time invested in leisure activities increased as well. Based on these results, this study discussed policy and practice implications regarding the support of adolescents' leisure activities.

Objectives: The purpose of this study was to evaluate the effect of nutrition education using materials based on social cognitive theory. Education topics focused on improving health-related and dietary self-awareness and behavior capability in adolescents. Methods: Participants were recruited from a middle school for girls; 67 students (educated group, n=34 and control group, n=33) participated. The education group received 12 lessons in club activity class. Self-administered surveys were conducted for each group before and after the nutrition education program. The questionnaires consisted of variables such as self-efficacy, outcome expectation, outcome expectancy, knowledge, and dietary practices based on the social cognitive theory. Education satisfaction was evaluated using a five-point Likert scale for two sections: a) teaching and learning and b) education results. The data were analyzed using a t-test and Chi Square-test (significance level: p < 0.05). Results: In the education group, post-education, there were significant differences in self-efficacy (p < 0.05), knowledge (p < 0.01), and dietary practices (p < 0.05), whereas outcome expectation and expectancy did not show any significant differences. None of the variables showed any significant differences in the control group. Educational satisfaction scores were $4.38{\pm}0.12$ (teaching and learning) and $4.14{\pm}0.15$ (education results). Conclusions: This study showed that improving adolescent's awareness and behavior capability has a positive effect on their dietary practices. Moreover, this study suggested that a theory-based determinant should be considered to improve dietary behavior among adolescents.
