Purpose: This study was performed to determine the levels of psychosocial distress among high school students to reveal the various related factors. Methods: Self-administered questionnaires were administered between June 1st and July 31th, 2006, to 992 different high school students in Daejeon City. The survey items included questions concerning the subjects' family and school life characteristics, health-related behaviors, sense of self-esteem, and locus of control. Results: The results showed that 27.8% of the subjects were categorized as high risk stress, 66.6% as latent stress, and 5.5% as normal. The level of psychosocial distress was found to be influenced by various related factors such as family and school life characteristics, health-related behaviors and personality traits (locus of control, self-esteem). Conclusion: The above results of the study suggest that the more stresses the high school students felt, the higher the correlation with self esteem and self control. Therefore, it is required that there be more development of programs designed towards harmonizing human relationships, promoting regular life styles and positive self perceptions; as well as building self confidence and assisting in course selection. Also, there is a need for further research and education in accessing effective strategies for coping with stress.

The relationship among food behavior, psychological factor(life strees) and perceive tiredness was investigated in 514 adolescents. Tiredness was measured in four cases: in lessons, before school, in the early evening and at weekends. Adolescents felt most tired in lessons and before school, and leat at weekends. Irregularity of meal times and skipping breakfast were positively correlated with tiredness in lessons and befor school. Consumption of some foods was related to perceived tiredness. High sugar or fat containing ice-cream, hamburger of fizzy drinks in boys, and crisps and cookies in girls were positively associated with tiredness. Whereas beans and mushrooms were negatively associated with tiredness in girls. Life stress(by scholastic problem and personal problem) of adolescents was positively related to tiredness. The contribution of stress to tiredness was much greater than of food behavior according to multiple linear regression .There was no relationship between nutrients intake and tiredness in lessons and before school which were more strongly influenced by stress, whereas the relationship was found at weekend without influences of stress. The more tired, the lower NARs(nutrient adequacy ratio) of energy, phosphorus, vitamin A, vitamin B$_2$, and niacin were. In conclusion, some eating behavior and psychological factor can cause tiredness in adolescents, but tiredness in school and before school had more of a psychological cause than at weekend.

For assessing residual lift of the steam pipe in fossil power plants, inspections and analysis are usually focused on the critical locations such as butt welds, elbows, Y-piece and T-piece of the steam pipes. In predicting the residual life of T-piece, determination of local stress near welds considering system load as well as internal pressure is not a simple problem. In this study, stress analysis of a T-piece pipe was conducted using a three-dimensional model which represents the T-piece of a domestic fossil power station. Elastic and elastic-creep analysis showed the maximum stress level and its location. Residual creep rupture life was also calculated using the stress analysis results. It was argued that the calculated life is reasonably same as the measured one. The stress analysis results also support life prediction methodology based on in-field replication technique.

이 연구는 코로나19 상황에서 초·중·고 학생의 삶의 만족도에 영향을 미치는 요인을 분석하였다. 연구 대상은 G광역시 전체 초등학생 5-6학년, 중학생 1-3학년, 고등학생 1-2학년을 전수조사하였다. 초·중·고학생 총 13,672명이 조사에 참여하였고, 이 중 13,613부를 최종 자료 분석에 사용하였다. 초·중·고 학생의 삶의 만족도에 영향을 미치는 요인을 위계적 회귀분석한 결과 학교생활 요인은 22.2%, 가정생활 요인을 추가하면 4.7%, 일상적 스트레스 요인을 추가하면 10.7%의 설명력이 증가하였다. 코로나19 상황에서 초·중·고 학생의 삶의 만족도에 가장 큰 영향을 미치는 요인은 가정생활 만족도였고, 그다음으로는 초등학생은 외모 스트레스, 중·고등학생은 학업 스트레스였다. 이는 코로나19로 인해 비대면 수업이 늘어나 학생들이 가정에서 보내는 시간이 많아지면서 학생들의 삶의 만족도에 가정생활 요인이 더 크게 영향을 미친 것으로 볼 수 있다. 그럼에도 중·고등학생은 여전히 학업 스트레스가 삶의 만족도에 큰 영향을 미치고 있음을 알 수 있다. 이를 통해 코로나19에 대응하며 학생들이 가정에서 관계, 소통, 학업, 여가 등을 보다 원활히 할 수 있도록 지원해야 하며, 특히 가정환경에 따라 비대면 수업으로 인한 학력 격차가 심화되지 않도록 다각도의 교육정책이 수반되어야 할 것이다.

Effect of quercetin on NO production and regulation mode of quercetin on oxidative stress, $NF{\kappa}B$ activation, and iNOS expression, possible mechanisms of NO suppression in LPS-stimulated macrophages were investigated. Treatment of RAW 264.7 cells with quercetin significantly reduced lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production dose-dependently ($IC_{50}$, $9.2\;{\mu}M$). Expression of iNOS and specific DNA binding activities of nuclear factor kB ($NF{\kappa}B$) were significantly suppressed by quercetin pretreatment. Quercetin reduced thiobarbituric acid-reactive substances (TBARS) accumulation, enhancing GSH level and antioxidant activities of enzymes, such as superoxide dismutase (SOD) and catalase. These results demonstrate quercetin may ameliorate inflammatory diseases by suppressing NO production through inhibition of iNOS expression, $NF{\kappa}B$ transactivation, and oxidative stress, which may be mediated partially by antioxidative effect of quercetin. Thus, quercetin appears to be used as a potential therapeutic agent for treating LPS-induced inflammatory processes.

This study was conducted to investigate the influence of obesity stress on the eating behavior of elementary school students. Using a questionnaire, 300 students in the sixth grade from 2 schools in Kyunggi-do were surveyed (Boys: N=145, Girls: N=155). Data analysis was managed by SPSS software (version 13.0). The link between obesity stress and eating habits or behaviors was dependent on physical discomfort. There was also a large group of students experienced irregularity in their meal times during the day. Furthermore, there were significant differences in mealtime among boys under psychic stress caused by obesity. In the case of dairy intake during breakfast, the significant signs of obesity stress for were physical discomfort for boys and psychic stress for the girls. It was found for both boys and girls that more frequent midnight snacking decreased the efforts to overcome obesity stress. Therefore, a professional nutrition program that can educate school children must be implemented both in school and at home. In addition to overweight or obesity children, normal weight and underweight children can also benefit from this program that includes health counseling for weight and eating behaviors.
