This study examined smoking behavior of Korean female college students by applying the Ajzen's Theory of Planned Behavior, and tried to uncover the factors influencing smoking behavior. The main findings are as follows: First, the attitude toward smoking behavior and the perceived behavioral control were statistically significant in predicting smoking intention. The smoking intention was also significant in predicting smoking behavior. Thus, in order to promote to stop smoking, smoking prevention education emphasizing to reduce smoking intention, to lower the positive attitude toward smoking behavior and to enhance the capacity for perceived behavioral control seems to be helpful. Second, the smoking intention influenced significantly over the smoking behavior in all situations. But the influences of the attitude toward smoking behavior, the subjective norms, and the perceived behavioral control over the smoking intention varied from not significant in one situation to significant in the other situation. Thus, different prevention programs according to the characteristics of individuals need to be developed. Third, in a path analysis, the grade and the degree of satisfaction with college life had the indirect influence, and the growth place had the direct influence over the attitude toward smoking behavior and smoking intention. Thus the smoking prevention program focusing on the students who are the first grade, less satisfied with college life, and growing up in small cities should be developed.

Disordered eating behaviors, such as overeating, are known to be contagious in the general population. The objective of our research is to find an optimal control strategy to reduce the social burden of unhealthy overeating behavior by establishing and analyzing a mathematical model for the social transmission dynamics of unhealthy overeating. We consider four compartments in the population: normal weight with normal eating behavior, normal weight with overeating behavior, overweight with normal eating behavior, and overweight with overeating behavior. Simulation results under various control scenarios show that integrated control measures may be necessary to reduce the growth rate of the overeating population.

In 2000s, the rapid growth of domestic and foreign fast fashion brands led to an increase in the frequency of shopping for consumers and a significant reduction in the average life span of fashion products. As the kinds and quantity of fashion products owned by individuals increase, the problem of rational clothing management becomes a new concern. The purpose of this study was to investigate the demographic, socio-psychological and purchase behavior factors influencing the frequency of closet cleanup behavior. A total of 278 questionnaires were analyzed. Frequency, exploratory factor analysis, reliability, t-test and regression analysis were used for data analysis using SPSS 22.0. This study results were as follows. First, the frequency of women's closet cleanup behavior was higher than that of men's closet cleanup behavior. Second, the number of brothers and sisters significantly affected the frequency of closet cleanup behavior. Third, the stronger the attachment to fashion products, the higher the frequency of closet cleanup behavior. Fourth, the lower the fashion product retention tendency, the higher the frequency of closet cleanup behavior. Fifth, the higher the frequency of purchasing fashion products, the higher the frequency of closet cleanup behavior. The results of current study provide various implications for educators and marketers who are interested in reasonable management behavior of fashion goods.

In this study, to propose the prediction method of the crack growth under flight-simulation loading, crack growth tests are conducted on 2124-7851 aluminum alloy specimens. The prediction of crack growth under flight-simulation loading is performed by the stochastic crack growth model which was developed in previous study. First of all, to reduce the complex load history into a number of constant amplitude events, rainflow counting is applied to the flight-simulation loading wave. The crack growth, then, is predicted by the stochastic crack growth model that can describe the load interaction effect as well as the variability in crack growth process. The material constants required in this model are obtained from crack growth tests under constant amplitude loading and single tensile overload. The curves predicted by the proposed model well describe the crack growth behavior under flight-simulation loading and agree with experimental data. In addition, this model well predicts the variability of fatigue lives.
