Stress is a global menace exacerbated by the advancement of industrialization. Failure of stress management is to a breakdown of the psychological and physiological protection mechanisms against stress. The aim of present study was to investigate the anti-stress potential of ginseng against immobilization stress. Male Sprague-Dawley rats (n=24) were divided into three groups; (i) control, (ii) immobilization stress (2hr daily, for 2 weeks), and (iii) immobilization stress (2 hr daily, for 2 weeks) plus oral administration of ginseng (200 mg/kg BW Id). Immobilization stress resulted in a significant inhibition of body weight gain by 45 % and a significant decrease in the tissue weights of thymus and spleen (p < 0.05). The concentrations of blood GOT and GPT were significantly increased in the immobilization-stressed group compared to the control group (p < 0.05). There were no differences in the blood cholesterol levels among groups. Ginseng administration in the immobilization-stressed group tended to reverse the lack of body weight gain and food intake, though not significantly. The ginseng-administered group showed a significant reversal in the stress-induced effect on spleen and thymus weight, increasing the tissue weights by 16% and 20%, respectively, compared to immobilization-stressed group (p<0.05). The plasma corticosterone level was significantly increased in the stressed group by 39 % compared to the control group (p<0.05), but ginseng administration significantly reversed the stress-induced increase in plasma corticosterone by 15 % compared to the immobilization-stressed group. The present study suggests that the anti-stress effect of ginseng is mediated by normalization of stress-induced changes in the circulating hormones and a reversal of tissue weight loss, thereby returning the body to normal homeostasis.

The purpose of this study was to analyze the research trends in children's daily stress from 1990 to 2009. A total of 97 articles were selected from 30 Korean journals in the field of child development, early childhood education, psychology and so on. We analyzed the trends of research focusing specifically on the participants, themes, and methodology by 5 years, and discussed the features of major stress scales. The results were as follows. Firstly, research on children's stress started in the first half of the 1990s and drastically increased in the latter half of that decade. In the following decade, more various journals dealt with articles on children's stress, and more studies were conducted on the intervention of stress. Secondly, many studies investigated the developmental change in stress, rather than focusing on the same age group. The younger preschoolers participated in studies as years go by, indicating that the age of suffering from stress was downward. Thirdly, most research used stress as a dependent variable to examine the factors affecting stress. Fourthly, questionnaires, observation and interview were used as methods to measure children's stress, while qualitative research was rarely conducted. Lastly, scales to measure children's stress should be revised and developed, especially for succeeding research in the area of early childhood.

The purpose of this study was to examine the effect of stress types and coping styles on the relationship quality with mothers-in-law perceived by sons-in-law. The data was collected from 300 sons-in-law aged 20~49 by using a survey questionnaire. The main results of this study were as follows: first, factor analysis yielded 4 types of coping(cognitive understanding coping, avoidant coping, direct behavior coping, and indirect behavior coping) and 7 types of stress(despising poor ability and condition, interference in daily life, son-in-law discrimination, wife discrimination, uncomfortable interaction, differences in lifestyle, and excessive demand). Second, the total stress perceived by sons-in-law in the relationship with their mothers-in-law was affected by avoidant coping and cognitive understanding coping. Finally, the relationship quality between mothers-in-law and sons-in-law was influenced by avoidant coping, uncomfortable interaction stress, direct behavior coping, differences in lifestyle stress, son-in-law discrimination stress, interference in daily life stress, frequency of meeting, cognitive understanding coping, indirect behavior coping, and age. Consequently, it was confirmed that sons-in-law's coping styles with stress from their mothers-in-law was more influential than the amount of stress perceived by sons-in-law on the relationship quality with their mothers-in-law. Especially, 'avoidant coping' among 4 styles of coping and 'uncomfortable interaction stress' among 7 types of stress influenced the relationship quality between mothers-in-law and sons-in-law the most.

This study examined the influence of university students' stress in their daily lives on game addiction, and investigated whether the human relation skills has a moderating effect on their daily life stress. For this study, surveys of 222 university students were collected and analyzed with SPSS 18.0 program. The results of this study are as follows: First, the participants displayed lower human relation skills as the level of stress from the studies increased. In contrast, the participants displayed higher human relation skills as the level of stress from future plans and family relations increased. Second, as the level of game addiction increased, human relation skills were found to be lower. Third, the university students' stress from daily lives had a static effect on game addiction. The participants displayed tendency of game addiction as they had high levels of stress from their studies, financial issues, future plans, values, family relations, and human relations with people apart from their family. Among the listed factors of stress, the stress from the studies most strongly influenced the participants to be addicted to games. Fourth, among the sub-factors of stress in the university students, issues in future plans and family relations significantly control the game addiction. Studies on this area has been insufficient. From the study, it is found that in order to prevent university students to be addicted to games, they must cope well with their stress. Furthermore, this study carries its significance in finding the results that human relation skills contribute as a part of dealing with stress.

Objectives: The purpose of this study was to analyze Influence of stress on oral health and quality of life. Methods: The participants were 172 students from 4 universities located in DaeJeon, South Korea. A questionnaire was administered, assessing the impacts of the general characteristics of the participants, temporomandibular joint (TMJ) symptoms, xerostomia, and halitosis on stress. And oral impacts on daily performance were also investigated. Data were analyzed using the Statistical Package for the Social Sciences 18.0. Results: The level of stress was higher in female, and the causes of stress was reported scholastic achievement, relations with professors, get a job. The students who were higher stress were more conscious of TMJ symptoms, xerostomia and halitosis(p<0.05). Stress was significantly positively correlated with TMJ symptoms (r=0.376, p<0.001), dry mouth (r=0.360, p<0.001), and bad breath (r=0.343, p<0.001). Oral Impacts on Daily Performance (OIDP) scores were significantly positively correlated with dry mouth, bad breath, TMJ symptoms, and stress. Regression analysis showed that 54.5% of the independent variables were related to OIDP scores. Stress and TMJ symptoms exerted a significant effect on OIDP scores. Conclusions: Stress among university students affects oral health and quality of life. Stress coping mechanisms and oral health care education programs should be developed and applied at universities.

The barometric factor is estimated at five stations in the Bay of Biscay from the linear regression between daily mean sea level and atmospheric pressure. The results show that the adjusted sea level change is important in amplitude in spite of the barometric response of the sea level to the atmospheric pressure. The cross-correlations between adjusted sea levels and the two components of wind stress suggest that the adjusted sea level is highly related to the longshore wind stress. The observed phase and the time lag between adjusted sea levels at adjacent stations aree consistent with the hypothesis of the northward travelling continental shelf waves.

This study examined the effects of the daily noise stress on body weight, feed intake and clinicopathological findings in Korean indigenous goats. A total of 14 male goats was divided into 2 groups (test and control) with same number (n=7), and exam was started 2 weeks later. This study composed 2 stages. First was noise stage i.e., noise (80-100 dB) inflicted on the test for 70 minutes each time (5 times/day), and have continued for 2 months. Second was no noise for 2 months. Body weight and daily gain in stress group was decreased compared with control group after imposing noise (first stage). However, these results were reversed after ceasing noise (second stage). Average daily feed intake was not significant different between two groups throughout the experimental periods. But, feed conversion ratio was lowerin control group than another. Clinicopathological findings including total protein, albumin, globulin, total bilirubin, total cholesterol, triglyceride, aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose, amylase, blood urea nitrogen (BUN), cortisol, total leucocytes and hemoglobin value showed no significant different between stress and control group.

In this study, 110 adults aged 40 to 69 years were surveyed from April 28, 2016, to May 28, 2016 to analyze their periodontal status according to daily stress, coping methods, and oral health behavior. The collected data were analyzed using the t-test, one-way analysis of variance, and hierarchical multiple regression. Daily stress levels of all subjects were most frequent potential risk 64.5% of the subjects, the high risk 19.1% and 16.4% of the health group. Regarding stress coping methods, active methods recorded 2.46, passive methods recorded 2.32. Regarding oral health behaviors, subjects brushed an average of 2.45 times daily, for an average of 2 minutes. Futhermore, 69.1% of subjects brushed before bedtime and 89.1% practiced scaling. Regarding periodontal status, the O'Leary index was 73.45, gingivitis index was 1.30, an average of 2.83 quadrants possessed a periodontal pocket. The hierarchical multiple regression analysis identified, type of employment (${\beta}=-0.348$), scaling (${\beta}=-0.253$), and age (${\beta}=0.244$) as factors that influence the number of quadrants possessing a periodontal pocket. These results confirmed that the oral health behavior of scaling, but not stress levels of coping methods, strongly influenced periodontal status.

Purpose: This study was done to provide fundamental data for developing a depression prediction model by discovering main factors that affect depression in patients who do maintenance hemodialysis. Method: The subjects were 191 patients doing maintenance hemodialysis selected from outpatient dialysis clinics at 9 major general hospitals, The Instrument tools utilized in this study were adapted from depression, fatigue, sleep disturbance, stress, adaptation, symptoms, daily activities, and role limitation and thoroughly modified to verify reliability and validity. The collected data was analyzed with a SPSS-PC 11.0 Window Statistics Program for real numbers, percentage, average, standard deviation, and multiple regression. Results: The correlation factor for depression was (M=2.54) fatigue(M=3.12), sleep disturbance (M=2.82), stress(M=3.04), adaptation(M=2.53), daily activities(M=2.24), symptoms(M=2.37), and role limitation(M=2.24). The strongest factor that affected depression was explained by symptoms of the patients who performed hemodialysis. The analysis of the factors that affected depression revealed a $58.4\%$ prediction in symptoms, stress, role limitation, and adaptation. Conclusion: It has been confirmed that the regression equation model(Depression=7.351 + .266$^{\ast}$symptoms + .260$^{\ast}$stress -.l89$^{\ast}$adaptation + .057$^{\ast}$fatigue) of this research may serve as a prediction factor for depression in Hemodialysis Patients.

The purpose of this study was to investigate infants' development, parenting characteristics, and the infants' daily routines by monthly family income, and examine variables related to infants' development. The 2010 data of the panel study on Koreans were used. The sample for this analysis was 1,802 children aged 21-23 months and their parents. The data were analyzed with ANOVA, Pearson's correlation analysis, and multiple regression analysis with SPSS version 18.0. The results were as follows: First, the development of infants differed by the family income. Infants' communication and problem solving skills in families with an income at the 25th percentile or below was lower than those above the 25th percentile. Second, parenting characteristics differed by family income. In the lower income group, the mother's parenting stress was highest, but the father's parenting time on weekends was lowest. Third, the most frequent activity of infants differed by family income. Playing with friends or caregivers was lowest, but watching TV and videos was highest in the lower income family group. Fourth, there was a relation among infants' development (communication and fine motor skills) and parenting characteristics (mother's parenting style, stress, and father's parenting time on weekends), and the infants' daily routines (playing with friends or caregivers). Fine motor development was affected by playing with a caregiver.
