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.

Inadequate military soldiers cause military fatigue and rejection such as reduced confidence in the military and combat power. The military developed and applied a self-adopting test as a psychological test system to identify soldiers who are not fit to serve in the military in advance and prevent accidents. In this paper, we propose the ontology design process to be used for identifying accident concerns and implement the behavioral patterns and symptoms of maladjustment soldiers as ontology. The ontology design process is validated consistency and suitability as a result of the performance evaluation of ontology implemented. Through ontology design for identifying maladjustment soldiers, it is expected to play an effective role in preventing accidents by providing objective criteria and sharing of information on accident concerns.

This study analyzed and verified the effects of a dietary education program for Korean young adults in single-person households. The dietary education program was conducted for five weeks (from November 10 to December 8, 2020) for Korean young adults in single-person households living in Seongbuk-gu, via four face-to-face education sessions and one online education session, including both theoretical lectures and practice. The effect of the dietary education program was analyzed through the Nutrition Quotient (NQ) questionnaire for adults provided by the Korean Nutrition Society, a dietary evaluation checklist questionnaire developed by the researchers, and photovoices. The average of 'Nutrition' score increased from 51.81 to 53.20, but there was no statistically significant difference. However, there was a significant change in the 'Moderation' category (p<0.05). As for the researcher-developed dietary evaluation, the average of the 'Importance' area rose from 3.77 to 3.99, but there was no statistically significant difference. The average of the 'Practice' area rose from 3.03 to 3.57, significant results were found (p<0.05). When the pre-/post-tests were compared by the sub-categories, four elements of 'Importance', i.e., balanced meals and avoided foods, and all five elements of 'Practice' were significantly improved (p<0.05). A total of 200 photovoices were analyzed according to Social Cognitive Theory. As a result of the analysis, the deterrents that help people eat healthy homemade food were 48% environmental factors, 30% behavioral factors, and 22% individual cognitive factors. The deterrents found to hinder participants from eating healthy homemade food were 72% environmental factors and 14% individual cognitive and behavioral factors. The results suggest that the dietary education program for Korean young adults in single-person households can be an effective tool that promotes self-motivation, behavioral changes, and improvements of the surrounding environment.

As PB market segments into premium market, PBs were drawing attentions in terms of creating profits as well as a means to differentiate building up store identity. The purpose of this study makes a comparative study on the difference of consumer attitude formation process in discount store and home-shopping distribution channel which are recently on the upswing. This paper investigated the consumer's attitude formation on the private apparel brand. Subjects of this study were consumers in their $20s{\sim}40s$ who are main customer groups of PBs. The data were analyzed by Structural Equation Modeling and Multi-Group Analysis of Amos 5.0 to verify the difference of the path between store PB and premium PB. Following are the results of the study. Consumer attitude formation path on PB grades showed statistically noticeable difference. In discount store PB, store evaluation didn't directly influence on consumer attitude formation but showed indirect effect. On the other hand, in home shopping premium PB case, product evaluation directly influenced on consumer attitudes with store evaluation. Hedonic attitude dimension connected with behavioral attitude(purchase intention) revealed difference in path. Also consumer's evaluation on variables in model turned out to be different according to brand grade.

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. For a wider use of this program, more research was recommend for a strategy development of program diffuse. (Korean J Nutrition 38(10): 873$\sim$879,2005)

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.
