As the lifespan of concrete structures increases, their load carrying capacity decreases owing to cyclic loads and long-term effects such as creep and shrinkage. For these reasons, there is a necessity for stress state monitoring of concrete members. Particularly, it is necessary to evaluate the concrete structures for behavioral changes by using a technique that can overcome the measuring limitations of usual ultrasonic nondestructive evaluation methods. This paper proposes the use of a nonlinear ultrasonic method, namely, nonlinear resonant ultrasonic spectroscopy (NRUS) for the measurement of nonlinearity parameters for stress monitoring. An experiment compared the use of NRUS method and a linear ultrasonic method, namely, ultrasonic pulse velocity (UPV) to study the effects of continuously increasing loads and cyclic loads on the nonlinearity parameter. Both NRUS and UPV methods found a similar direct relationship between load level and that parameter. The NRUS method showed a higher sensitivity to micro-structural changes of concrete than UPV method. Thus, the experiment confirms the possibility of using the nonlinear ultrasonic method for stress state monitoring of concrete members.

Impact and process evaluations were performed in order to verify the effectiveness of a public health nutrition program developed for child-bearing aged women in Korea. Participants included 58 high school girls who were divided into two groups. Each group received four 50 - 60 minute nutrition education lectures regarding healthy eating, osteoporosis, constipation and nutrition labeling in every two weeks. Each session took 50- 60 minutes. Regarding nutrition knowledge, there was a significant increase of degree of perception (p = 0.0004) , but no change in degree of accuracy after implementation (p = 0.9522) . Nutrition education was also effective in attitude change, showing more participants were ready to change their eating behaviors in terms of meal regularity (p = 0.0455) and less processed food intake (p =0.0143) . After implementing nutrition education, effective behavioral changes were observed in milk consumption (p =0.0037) and meal regularity (p = 0.0882) as well as daily activity such as stair use (p = 0.0701) . However, nutrition education had no effect on body mass index and perceived health status. In process evaluation conducted by a 9 item questionnaire, grand mean score was $4.17 \pm$0.72 out of 5. Proportion of items with scores higher than 4 ranged $68-91\%$. These results suggest that the nutrition education program used in this study was effective and useful.

Objectives : This study examined psychopathology, abuse history and the relation of them in sheltered runaway adolescents. The purpose is to investigate characteristics of adolescents who are in shelters according to abuse type and then to offer basic data which are needed in establishing comprehensive protection policy for runaway adolescents. Methods : One hundred twenty eighty adolescents who stay in the runaway shelters were asked to complete self-report questionnaires including basic sociodemographic data, Korean Youth Self Report (K-YSR), Minnestota Multiphasic Personality Inventory (MMPI), and Symptom Checklist-90-Revised (SCL-90-R) and then examined the correlation of psychopathology and abuse in runaway adolescents. Results : In abused runaway adolescents, social performance scale of K-YSR was higher than school performance sealer and among scales of behavioral problem syndrome delinquent scale was highest. Scales of behavioral problem syndrome showed relatively significant correlation with abuse history. In MMPI scale of psychopathic deviate scale was highest, social introversion showed significant correlation with emotional abuse, and psychopathic deviate and hypomania showed significant correlation with physical abuse, neglect and sexual abuse. In SCL-90-R somatization scale was highest. Scales of somatization, hostility, and paranoid ideation scale were significantly high in adolescents with emotional abuse and neglect history, and scores of anxiety and depression scale were significantly high in sexually abused adolescents. Conclusion : Runaway adolescents who had abuse experience showed significantly higher level of psychopathology than general adolescents and there were various interrelations between them according to the presence and the type of abuse. More precise psychiatric evaluation and detailed treatment intervention for runaway adolescents are needed.
