The study proposes an exploratory analysis on the success of animation films in Korea industry. It identifies animation films that have been successful in the Korean film industry during 2004-2013 period and explores (1) how the number of screens allocated to the films have been changed; (2) what are the major factors that influence the success of the films; (3) what are the differences between Japan and the US animation in terms of plots and genres; and (4) how the characteristics of the US animations are related to the success of the US market, the global market, and Korean market. Analyses show that the number of screens allocated to the animation films has been consistently increased due to the vertical integration of Korean film industry; and the (FTA) period, months in year (summer and winter break months for middle and high school students), and the number of screens allocated to the films were the major factors influencing the financial success of animations. It also finds that specific characteristics embedded in its own cultural trait were shown in the plots and genres in the animations. Lastly the study also finds that specific set of characteristics extracted from IMDB site influence certain markets. Budgets and actor's power were found to influence the success in the US market while period (pre-FTA, FTA, post-FTA) only influence the success in Korean market. The study points out that the success of the US and Japan animations in Korean film industry are due to the historicity of animation cultures which are not found in Korean animation industry.

The modern society as a high-level information-oriented society lays a great emphasis on lifelong education. It emphasizes all the learners' creative learning ability and various teaching-learning methods as well. We need the self-directed learning to meet these requirements, and one of the solutions is the self-directed teaching-learning process employing the web. Though many educators, so far, developed a number of teaching materials, they are no more than web-based teaching materials for simple learning activities or simple item-bank systems. So, this paper suggests an problem-solving based and self-directed learning system on web in order to overcome such simplicities, and it shows design and implementation of the system. Suggested learning system enables learners to get thinking skill though self-directed control of learning level after they learn the basic concepts and principles on the web as self-directed learning. For example, the system was applied to mathematics education for a middle school students. It supports a test of questions chosen from the item bank in a self-directed way, and helps learners to understand their learning levels for themselves and to solve their questions through on-line discussions with their instructor. The system can also be helpful in improving the learners' learning effects by sharing mutual information through the data room or the Q&A between learners and learners or between learners and instructors.

Objectives: This study examined the association between dietary behaviors and perceived health status among Korean adolescents from multicultural families. Methods: This cross-sectional study included 2,459 Korean adolescents from multicultural families (aged 13 ~ 18 years) who participated in the 2017 ~ 2019 Korea Youth Risk Behavior Surveys. Information on the sociodemographic variables, dietary behaviors, and lifestyle variables was self-reported using a web-based questionnaire. The dietary behaviors analyzed in this study were the breakfast and food intake frequencies, including fruit, vegetable, milk, fast food, carbonated drink, sweet drink, and high caffeine/energy drinks. The adolescents' health perception was self-rated as healthy, average, or unhealthy. The dietary behaviors associated with health perception were examined using a multiple logistic regression after adjusting for the confounding variables. Results: In this study population, 7.6% of adolescents perceived their health status as unhealthy, and 25.4% perceived it as average. The adolescents who were girls, middle school students, and in households with a low economic status showed significantly higher percentages of poor health perception (P-values < 0.001). Skipping breakfast was significantly associated with a negative health perception. Compared to the adolescents who consumed fruits every day, those who did not consume fruits during the previous week showed a higher odd ratio (OR) for a negative health perception [OR = 2.29, 95% confidence interval (CI) = 1.32-3.97]. The adolescents who frequently consumed carbonated drinks (≥ 5 times/week) perceived their health status as unhealthy relative to those who did not consume carbonated drinks (OR = 2.15, 95% CI = 1.25-3.71). Skipping breakfast was significantly associated with an increased OR for a negative health perception in girls but not in boys. Compared to adolescents with a normal weight, those with overweight/obesity (OR = 1.75, 95% CI = 1.21-2.52) and underweight (OR = 2.19, 95% CI = 1.25-3.82) showed higher ORs for negative health perception. Positive associations of overweight/obesity and underweight with negative health perception were observed in boys but not in girls. Conclusions: Dietary behaviors and weight status were associated with the health perception in Korean adolescents from multicultural families. These findings suggest that nutrition interventions on breakfast intake and healthy food choices for this population might effectively improve their weight and perceived health status.
