This study aimed to investigate the mediating effect of hope between stress and suicidal ideation of adolescents. For the study, 399 adolescents were surveyed at 10 cities of Korea from May to August in 2010. Main results of the study were in the followings. First, it was found out that stress of adolescents was positively correlated with suicidal ideation, hope was negatively correlated with suicidal ideation, and stress influenced more suicidal ideation than hope. Second, suicidal ideation of adolescents tended to be low, stress was in the middle level, and agency and pathways thinking of hope was higher than middle level. Third, it was proved that agency and pathways thinking of hope was mediated between stress and suicidal ideation of adolescents. Lastly, for the female adolescents living in the metropolitan and large cities, only agency thinking of hope was mediated but pathways thinking was not mediated. Policy implications for preventing and decreasing adolescent's suicide were suggested.

This study was conducted to check critical thinking disposition, academic self-efficacy, and self-directed learning ability, and to understand the effect on self-directed learning ability for nursing students. Data were collected from 268 nursing students in the 3rd and 4th grades of two universities. As a result of the study, it was found that there was a significant positive correlation between critical thinking disposition, academic self-efficacy, and self-directed learning ability of nursing students. The factors affecting the self-directed learning ability of nursing students were critical thinking disposition, academic self-efficacy, major satisfaction, and personality disposition, which accounted for 68% of self-directed learning ability. Therefore, in order to improve self-directed learning ability, it will be improved if the critical thinking disposition can be improved through the curriculum, and academic self-efficacy and major satisfaction are increased by applying various teaching and learning methods and programs.

In recent years, the rapid growth of vehicles have increased traffic crashes. Since they can cause the economic losses and have put the life qualify in danger, there should be numerous efforts to reduce traffic crashes. To reduce traffic crashes, this research seeks to improve the safety of intersections by analysing causations of injury severity with Ordered Probability Model. This research applied the Ordered Probit Model, which assumes that ${\epsilon}_i$(random error) is normally distributed, for model calibration and used $p^2$ (likelihood ratio) and $x^2$ (Chi-square) for model selection. The results show that minor road traffic, heavy vehicle rates, major and minor right-turn rates, presence of lightings, speed limits, instructive line for left-turn traffic are significant factors affecting crash severities at signalized intersections.

This study deals with the side right-angle collisions of 4-legged signalized intersections in Cheongju. The goals are to analyze the characteristics of accidents and to find out the accident factors that affect severity using ordered probit model. In pursuing the above, the study uses the data of 580 side right-angle collisions occurred at the 181 intersections(2004-2005). The analyses show that more accidents were occurred in the nighttime and in going straight. The main cause was analyzed to be the red-light violation. Also, the main results of modeling are the following, First, the likelihood ratio index is 0.094 and t-ratio values that explain goodness of fit are significant. Second, minor road traffic volumes, minor road lanes, major road left-turn lanes, major road left-turn signal, major road yellow signal time, cross angle, major and minor road speed limits are significant factors affecting crash severities at signalized intersections.
