The purpose of this study is to find the effect of group counseling program based on reality therapy that is developed by researcher and to investigate whether the program can decrease the academic stress of elementary school students. For this study, firstly a framework for academic stress decrease programs is established and a program is developed in accordance with the framework. Secondly, in order to verify the effect of the program, both quantitative and qualitative methods were applied to 6th grade students through a academic stress test. Experimental group and control group is composed of 18 students, each. During a two month-experimental period, group counseling program based on reality therapy was implemented to the experimental group for 10 sessions but not to the control group. The program included nicknaming, recreation activities to promote friendliness among participants and other various activities to decrease the academic stress. The results of the quantitative and statistical research are as follows: First, group counseling program based on reality therapy is effective to decrease of elementary school students' academic stress. Second, sub factor(such as perceptions of academic stress cause, symptoms of academic stress)of academic stress is significantly decreased in experimental group. But no significant difference is found in control group. Third, for some sub factor(career, friend-relationship, house-environment, behavior-symptom), an independent-sample test and a paired-sample test showed different results: the paired-sample test showed no significant differences in experimental group while the independent-sample test showed significant decrease of academic stress. The results of the qualitative research based on student commentaries on the program is as follows: First, experimental group students report that the program based on reality therapy was effective to decrease of academic stress. Second, experimental group students' commentaries shows that students could remember the WDEP, 'act' factor and acquire the solution of academic stress. Third, for a group counseling, students reported the interest about positive feedback, searching on themselves, growth of human-relationship. This means that the program developed on this study is suitable for group counseling program. In conclusion, this study proves that group counseling program based on reality therapy is effective to decrease of elementary school students' academic stress by increasing individual internal-control. Therefore, it is necessary that we should develop and apply similar program to elementary school students in other to decrease students' academic stress. school students in other to decrease students' academic stress.

The purpose of this study was to investigate the effects of elementary school students' stress and social support on smartphone addiction and school adjustment. Our hypothesis is that stress and social support of elementary school students affects smartphone addiction and school adjustment. In addition, the study model assumes that stress and social support of elementary school students were mediated by the effects of smartphone addiction. Analysis results found that elementary school students' stress affects smartphone addiction and school life adaptation, and social support influences school life adaptation. Elementary students' smartphone addiction has little influence on school life adjustment. Stress in elementary school students has a strong influence on smartphone addiction, social support, and adaptation to school life. In other words, higher stress levels results in higher frequency of use of smartphones, which may directly affect smartphone addiction and the ability to adapt to school life. The effects of stress and social support of elementary school students on school life adaptation and smartphone addiction were ultimately indirect. Based on the research results, this study suggests policy implications for elementary school students' addiction to smartphone and ability to adapt to school life.

Thermal barrier coating(TBC) applied to fighter and turbine engines is a technology that improves the durability of core parts by lowering the surface temperature of base material. The thermal stress caused by mis-match of the coefficient of thermal expansion between the top coating and the TGO interface is the main cause of TBC breakage. Since the thermal stress is dependent on the microstructure of the TBC, designing microstructure of TBC can improve the durability as well as lower the thermal stress. In this study, the effect of coating thickness, volume of porosity and vertical cracking on the thermal stress was analyzed through finite element analysis. Through the analysis results, a design range of a microstructure that can improve the durability of thermal barrier coating by lowering thermal stress is proposed.

The purpose of this study was to examine the effect of children's academic stress on school adaptation and to verify whether ego-resilience plays a mediating role in the relationship between academic stress and school adaptation. Based on the data from the 12th year of the Korean Children's Panel (2019), the general characteristics of the main subjects and the mean, standard deviation, skewness and kurtosis of the main variables were confirmed through basic statistical analysis, and correlation analysis was conducted between variables. In addition, to examine whether ego-resilience mediated the effect of academic stress on school adaptation, a three-step regression analysis was conducted following the procedure of Baron and Kenny. The results of this study were as follows. First, it was found that children's academic stress, school adaptation, and ego resilience were all significantly correlated. The higher the academic stress, the lower the ego-resilience and school adaptability. Second, it was confirmed that ego-resilience has a partial mediating effect in the relationship between children's academic stress and school adjustment. Ego resilience in the academic stress situation means that it acts as an important mediating factor to flexibly adapt to school life by objectively grasping and coping with the stress situation. Therefore, we need to recognize the need for flexible and resilient individual characteristics so that children can reduce academic stress and adapt well to school life, and seek active interest and intervention plans.

BACKGROUND/OBJECTIVES: Dietary behavior and life stress in adolescence is related to growth rate and learning ability. This study was conducted to identify the relations between dietary habits, dietary attitude nutritional knowledge and life stress among high school girls in Korea and China. SUBJECTS/METHODS: The subjects of this study were 221 high school girls in Korea and 227 high school girls in China. The questionnaire were about dietary habits, dietary attitude, nutritional knowledge and life stress. RESULTS: The dietary habits of chinese girls were healthier than those of Korean girls with a significant difference (P < .001). There was no significant difference in dietary attitude between Korean girls and Chinese girls. Korean girls had more nutritional knowledge than Chinese girls with a significant difference (P < .001). Korean girls did less physical exercise but spent more time watching TV and using PCs, compared to Chinese girls. Korean girls' degree of confidence in nutrition information that they had learned and their performance in their real lives were low. Also, they had a low level of awareness of the need for nutritional education. There was no significant difference in life stress between the two groups. Dietary habits had a significantly negative correlation with life stress in both Korean and Chinese girls (P < .01, P < .001). As for Chinese students, dietary attitude had a negative correlation with life stress with a significant difference (P < .05). As for Korean girls, nutritional knowledge had a negative correlation with life stress with a significant difference (P < .05), which means as life stress was less, dietary habits were better. CONCLUSIONS: This study shows that effective nutrition education programs should include components that encourage application of learned nutrition information to real life, increase physical exercise and reduce life stress.

Background: Obesity is a risk factor for aging and many diseases, and the disorder of lipid metabolism makes it prominent. This study aims to investigate the effect of ginsenoside Rg1 on aging, lipid metabolism and stress resistance Methods: Rg1 was administered to Caenorhabditis elegans (C. elegans) cultured in NGM or GNGM. The lifespan, locomotory activity, lipid accumulation, cold and heat stress resistance and related mRNA expression of the worms were examined. Gene knockout mutants were used to clarify the effect on lipid metabolism of Rg1. GFP-binding mutants were used to observe the changes in protein expression Results: We reported that Rg1 reduced lipid accumulation and improved stress resistance in C. elegans. Rg1 significantly reduced the expression of fatty acid synthesis-related genes and lipid metabolism-related genes in C. elegans. However, Rg1 did not affect the fat storage in fat-5/fat-6 double mutant or nhr-49 mutant. Combined with network pharmacology, we clarified the possible pathways and targets of Rg1 in lipid metabolism. In addition, Rg1-treated C. elegans showed a higher expression of anti-oxidative genes and heat shock proteins, which might contribute to stress resistance Conclusion: Rg1 reduced fat accumulation by regulating lipid metabolism via nhr-49 and enhanced stress resistance by its antioxidant effect in C. elegans.
