The Implementation Semi-Public Management System of Intra-City Bus brings improvements of the position stability, work environment and welfare of the bus drivers. As these benefits prevent drivers' job changes, average age of the drivers increases. Some side effects such as fatality increase after the implementation of the new system are becoming social problems. To minimize such problems, it is necessary to prepare the measurements reflected drivers' age increase and driving characteristics of old drivers to decrease traffic accidents of intra-city buses. The existing measurements are mostly simple policy. To get over such limitations, this study grasped driving characteristics by surveys and driving aptitude test targeting old drivers and non-old drivers who brings about traffic accidents actually. As a result, the characteristics of the old drivers were understood precisely. The measures of decrease of the traffic accidents are suggested by the analysis of the behavior characteristics of the old drivers through the structural equation model.

This study verified the effects of violent PC games and aggressive personality on aggressive behavior and aggressive intention as predicted by GAM in Anderson and Bushman (2002), and a correlational study and experimental research were carried out to corroborate a differences of the effects of the two variables according to the developmental levels. The correlational study showed that aggressive personality was an explanatory variable for aggressive behavior; however, exposure to violent PC games was not a significant factor, contrary to the predictions by GAM. It has been clarified that the effects of the two variables influenced aggressive behavior in a different way according to the developmental levels. Further, no positive relation existed between repetitive (chronic) violent PC game plays and aggressive personality. The experimental research analyzed the differences of aggressive intention in each of the experimental conditions designed with a 2(PC games types: violent vs. non-violent) x 2(aggressive personality: high vs. low) x 2 (developmental levels: middle school boys and college students) between-subjects factorial design. As a result, violent PC games had an effect on aggressive intention for the middle school boy group, while it was supported that aggressive personality had an effect on aggressive intention for both middle school and college students. Noticeably, the primary hypothesis in the study has been supported that the effects of violent PC games and aggressive personality on aggressive intention vary according to different age groups. In conclusion, the effects of violent PC games and aggressive personality as predicted by GAM have been confirmed in parts; however, future studies on GAM must be necessarily supplemented with the developmental perspectives, as it has been ascertained that the effects of the variables vary according to the developmental levels.

This study analyzed the correlation of work values, career attitude maturity and employment preparation behavior by determining the sociodemographic characteristics, and the study confirmed the validity of the influence of work values and career attitude maturity on employment preparation behavior. The subjects of this study were 218 nursing students at a university located in Geonggi-do. The data was collected from June 4th to August 27th, 2019 by using structured questionnaires. As a result, female students scored significantly higher in work values and career attitude maturity than did the male students, and the students who had better grades showed higher employment preparation behavior. In addition, the result showed positive correlation between work values and employment preparation behavior, and the study showed correlation between career attitude maturity and employment preparation behavior. Greater independence, readiness, certainty, and decisiveness were higher and were sub-factors of career attitude maturity and employment preparation behavior. Moreover, the higher the students' patriotism and indoor activities, the higher was their employment preparation behavior. In conclusion, the employment preparation behavior was higher according to greater work values, while the influence of career attitude maturity on employment preparation behavior was not statistically significant.

This experiment was carried out to determine the effect of breed and sex on behavioral characteristics and economic traits of performance-tested pigs. Totally 32 tested pigs in 4 different breeds were assigned for behavioral observation. Behavior was recorded for 4 hours(each 2 hours, before and after none) of tested pigs in each tested pen. The average daily gain, age at 90 kg and feed efficiency on the basis of the performance data were collected from 8,477 performance-tested pigs in which pure breeds of Duroc, Yorkshire, Landrace and Berkshire at the Korea Swine Testing Station. The results obtained in this study are summarized as follows; The effect of breed was statistically significant for all traits studied. Average daily gain were the highest(P<0.05) in Duroc and ages at 90 kg were the highest(P<0.05) in Berkshire. In feed efficiency of male, Landrace and Yorkshire were the most efficient. The average daily gain and feed efficiency were superior to those of female, however, the age at 90 kg was not different. Overally, females were superior to males in various traits examined. Berkshire breed had more proportion of time spent in ventral tying and sitting whereas the proportion of time spent in walking, drinking and eating was less than that of other breeds. The male pigs showed more time spent in standing and social behavior.
