Purpose : Acute gastroenteritis is a frequent childhood disease. The purpose of this study is to determine if certain pathogens are related to more severe clinical disease in children with acute gastroenteritis. Methods : Two hundred seventy one stool samples were obtained from pediatric patients with acute gastroenteritis that was associated with virus, bacteria and protozoa infection between January 2006 and December 2006. The clinical severity was assessed by using the 24 point scale Clark score. We evaluate the Clark score according to the pathogens. Results : One hundred thirty seven children were noted to have virus, bacteria or protozoal infection. Rotavirus was the most common pathogen found in the children with gastroenteritis (20.6%). Other frequent pathogens were norovirus (10.7%) and E. coli (12.9%). Vomiting (P=0.049) and diarrhea (P=0.003) symptoms were more frequent in the rotavirus group than that in the rotavirus negative group. There were no statistical differences in the Clark score between the virus positive group and the virus negative group. Conclusion : We concluded that rotavirus was the most common pathogen in children with gastroenteritis, yet the clinical severity was not dependent on the presence of viral or bacterial pathogens.

Purpose: The purpose of this study was to -retrospectively describe the childhood sports activity level of Korean adult men and women and to determine whether a higher level of childhood sports activity was positively associated with adult bone mineral density. Methods: A cross-sectional study of 100 Korean men (n=40) and women (n=60) was completed. Participants completed a detailed lifetime sports activity questionnaire and had their bone mineral density of the femur and lumbar spine measured using dual energy x-ray densitometry (DEXA). All sports activities were classified into four categories of peak strain score on the basis of ground reaction forces (GRF). Results: During the age of high school, women and men who participated in a high intensity sports activity demonstrated higher bone density in the femur site after adjustment for the effects of body weight, fat body mass, lean body mass, the level of calcium intake, and breast feeding period than those who did not participate in sports activity at all. Conclusion: These results highlight the need to participate in high intensity sports activity during high school age as a means of increasing peak bone mass in the femur site.

The present research investigated the influence of the enlistment motivation on an image of military organization, soldier's stress, a confidence of social life after discharge from military service and military life satisfaction in Korean military service. Participants of this research were 257 soldiers (121 conscript Army soldiers and 136 voluntary Marines) from 2 companies in the army and 2 companies in the Marine Corps located in South Korea. Results of this study showed that 1) conscript Army group(M=2.39, SD=.71)had a significantly higher score than voluntary Marines group(M=1.95, SD=.63)in extrinsic enlistment motivation. On the contrary, Marines group(M=4.16, SD=.76) had a significantly higher score than Army group(M=3.62, SD=.87) in intrinsic enlistment motivation. 2) Enlistment by intrinsic motivation has positive influence on the military life. Result of Regression analysis showed that enlistment by intrinsic motivation significantly predicted a military life satisfaction(𝛽=.402, t=6.424, p<.001), a confidence of social life(𝛽=.528, t=9.836, p<.001), and an image of military organization(𝛽=.494, t=8.486, p<.001). On the other hand, enlistment by extrinsic motivation has negative influence on the military life. Result of Regression analysis showed that enlistment by extrinsic motivation significantly predicted the soldier's stress in military life(𝛽=.415, t=6.642, p<.001), and no confidence of social life(𝛽=-.177, t=-3.306, p<.001). These results suggest that Korean military needs to focus on enhancing intrinsic enlistment motivation of young men of conscription age before conscription by educating, and advertising etc. And also, we discuss that Korean military needs to consider how to boost intrinsic motivation of military life.
