Purposes： This study was to examine the effects of empowerment education programs on empowerment and mental health in high school students. Methods： This study involved a nonequivalent control group pre-test and post-test design. The subjects for this study consisted of 421 high school students who attended two general high schools in Busan. The 211 students in the experimental group received empowerment education training, while the 210 students in the control group did not. The data were collected from March 2, 2004 to July 20, 2004. The empowerment education program consisted of 17 separate 50-minute sessions. The questionnire was developedby authors and revised it based on experts' advice. SPSS 11.0 program was used to analyze the data. Chi-square test and t-test were used to test the homogeneity of general characteristics and dependent variables. Student's t-test was used to evaluate the differences between the experimental group and control group after the treatment. Results： Just as we hypothesized, the experimental group exhibited higher empowerment scores than the control group. For subcategory, Score of self-efficacy and self-esteem increased significantly in the experimental group compared to the control group. However, the score of decision-making ability did not increase significantly. The data failed to support our second hypothesis that the experimental group would have higher mental health scores than the control group. Although the score of self-scale increased significantly in the experimental group compared to the control group, the score of social-support and psychopathology did not. Conclusions： Empowerment education programs are effective for empowerment of high school students. However, such training is effective only for promoting the self scale but not overall mental health. Thus, we suggest the application of the empowerment education program to make high school students aware of their abilities. Furthermore, we suggest the implementation of mental health programs to supplement such empowerment education programs.

Compared with classical linear controllers, a nonlinear controller can result in better control performance for the nonlinear uncertainties of continuously variable transmission (CVT) systems that are driven by a synchronous reluctance motor (SynRM). Improved control performance can be seen in the nonlinear uncertainties behavior of CVT systems by using the proposed mingled revised recurrent Hermite polynomial neural network (MRRHPNN) control with mend ant colony optimization (ACO). The MRRHPNN control with mend ACO can carry out the overlooker control system, reformed recurrent Hermite polynomial neural network (RRHPNN) control with an adaptive law, and reimbursed control with an appraised law. Additionally, in accordance with the Lyapunov stability theorem, the adaptive law in the RRHPNN and the appraised law of the reimbursed control are established. Furthermore, to help improve convergence and to obtain better learning performance, the mend ACO is utilized for adjusting the two varied learning rates of the two parameters in the RRHPNN. Finally, comparative examples are illustrated by experimental results to confirm that the proposed control system can achieve better control performance.

The researcher has studied the types of accidents and injuries that most often occur to infants, toddlers and preschool children. Using this knowledge, a first aid program was developed for mothers. This researcher used a Quasi experimental study which consisted of a nonequivalent control group pretest - posttest design for injury first-aid knowle. The experimental group consisted of 32 mothers, and the control group consisted of 29. The education program consisted of the types of injury, the structure and function of skin, the methods of obsevation, first-aid awareness, and the standard of professional support in case of contusion, abrasion, laceration, fracture and burn. The education program was developed and based on 'the systemetic design of instruction' by Dick & Carey(1996) and utilized multimedia text book, pictures, examples, practice and discussions to increase understanding and effectiveness of learning. The data for this study was collected from September to early November, 2001. There were two fomative evauations, pretest and posttest with an intervention of education program. The analysis of the collected data was analyzed by descriptive analysis, ANOVA, t-test and paired t-test using the SPSS 10.0 program. The results as follows; 1. The experimental group, who was given an education program before the test, got higher marks on the injury first-aid knowledge than the control group. There was a significant difference in knowledge between experimental group and control group(t=6.578, p=.000). 2. The experimental group got higher marks on the action evaluation than the control group. There were significant differences in the certainity of action (t=8.546, p=.000) and the accuracy of action (t=7.654, p=.000) between experimental group and control group. This study examined how a first aid education program increased effectiveness in the knowledge and action of injury first-aid.
