This study attempted to compare the social interest, motivation, and attitude of nursing college students who participated in a voluntary program and the students who didn't participate in a voluntary program. The purpose of this study can be summarized as to find the effect of a voluntary program and to offer fundamental data for institutionalizing a voluntary program in college. The subjects were composed of two groups, one group attend the voluntary program and the other group doesn't. The subjects were 390 nursing students: 179 in the experimental group and 211 in the control group. The results of this study are as follows : 1. Before voluntary activities, the mean value of the control group was higher than that of the experimental group in social interest and altruistic motivation. The difference is statistically meaningful(t= -2.2.53, p=.25, t= -2.509, p= .013). 2. After voluntary activities, selfish motivation and altruistic motivation in the experimental group was higher than before. The difference is statistically meaningful(t= 2.404, p=.0l7, t=-2.751, p=.007). 3. The social interest, selfish motivation, altruistic motivation toward voluntary activities and selfish attitude, altruistic attitude toward voluntary activities will not have changed in the control group before or after voluntary program. However, the altruistic attitude lowered after voluntary activity. It is statistically meaningful(t=2.694, p=.008). 4. After the voluntary activities, there was a significant difference between the experimental and control groups in altruistic attitude. In the experimental group, the mean value of altruistic attitude increased significantly, but in the control group the mean value of altruistic attitude decreased ( t = 2.15, p = .032). The results of this study showed that voluntary activities not only increase social interest and altruistic attitude, but also the subject's understanding toward the community. 3. The social interest, selfish motivation, altruistic motivation toward voluntary activities and selfish attitude, altruistic attitude toward voluntary activities will not have changed in the control group before or after voluntary program. However, the altruistic attitude lowered after voluntary activity. It is statistically meaningful (t=2.694. p=.008). 4.

This research analyzed the effect of activity-centered reading band on Korean fairy tales on children's reading attitude and comprehension. The reading altitude of the experimental-group children exhibited more meaningful change in such subordinate areas as academic reading attitude. The academic reading attitude of the male experimental-group had higher improvement than that of the female experimental-group. In addition, the reading comprehension scores of the experimental-group children were higher than those of the control-group children. The reading program effects on reading comprehension were more meaningful in girls in the experimental group than boys in the group. Therefore, the results of this study have demonstrated the necessity of the development and application of a Korean fairy tales program for reading and an activity-centered reading program.
