Purpose: This study was conducted to examine the longitudinal effects of parenting stress and parental control attitudes on problem behaviors in preschool children, using a latent growth model. Methods: Participants were 1,724 pairs of parents and 1,724 preschool children who had completed the panel survey on Korean children ($5^{th}{\sim}7^{th}$ survey panels). Results: An analysis of the multivariate latent growth model of parenting stress, parental control attitudes, and children's problem behaviors suggested that the parents' intercepts for parenting stress influenced their intercepts for parental control attitudes (father: ${\beta}=.21$, p<.001; mother: ${\beta}=.55$, p<.001). In addition, the slopes for fathers' parenting stress was the only aspect that affected the slopes for mothers' parental control attitudes (${\beta}=.77$, p<.001). Moreover, both the intercepts and slopes of parenting stress and parental control attitudes significantly affected the children's problem behaviors. Conclusion: This study is significant as it provides longitudinal evidence of the impact of parenting stress and parental control attitudes on children's problem behaviors. The findings suggest that accurately assessing changes in parenting stress and parental control attitudes and developing intervention programs to reduce them will be effective in reducing problem behaviors in children.

This study examined the moderated effects of self-control on the relationship between elementary school children's excessive use of the Internet and their stress levels. The participants were 403 elementary school children from Chungnam-do. The instruments used were the 'Internet Addiction Autodiagnosis Scale (K-Scale)', the 'Stress Scale' and the 'Self-control Rating Scale'. The collected data were analyzed by t test, F test and the Scheffe test for a post hoc test, Pearson's partial correlation and stepwise multiple regression, and Cronbach's ${\alpha}$ for reliability by SPSS program (17.0 version). The results were as follows : First, it was found that there were significant differences in terms of excessive use of the Internet, stress levels, and self-control by gender, grade, academic achievement, the beginning year of first Internet access and the number of hours of Internet usage hours per day. Second, there were significant positive correlations between excessive use of the Internet (r = .40, p < .001) and stress levels (r = .44, p < .001) and the immediate satisfaction of self-control. Finally, the immediate satisfaction of self control was seen to moderate the relationships between the total scores for the excessive use of the Internet and stress levels and between withdrawal of excessive use of the Internet and the accompanying stress levels.

To understand molecular mechanisms underlying adaptation of plant cells to saline stress and stress memory, we developed Arabidopsis callus suspension-cultured cells adapted to high salt. Adapted cells to high salt exhibited enhanced tolerance compared to control cells. Moreover, the salt tolerance of adapted cells was stably maintained even after the stress is relieved, indicating that the acquired salt tolerance of adapted cells was memorized. In order to characterize metabolic responses of plant cells during adaptation to high salt stress as well as stress memory, we compared metabolic profiles of salt-adapted and stress-memorized cells with control cells by using NMR spectroscopy. A principle component analysis showed clear metabolic discrimination among control, salt-adapted and stress-memorized cells. Compared with control cells, metabolites related to shikimate metabolism such as tyrosine, and flavonol glycosides, which are related to protective mechanism of plant against stresses were largely up-regulated in adapted cell lines. Moreover, coniferin, a precursor of lignin, was more abundant in salt-adapted cells than control cells. Cell morphology analysis using transmission electron microscopy indicated that cell wall thickness of salt-adapted cells was significantly induced compared to control cells. Consistently, salt adapted cells contained more lignin in their cell walls compared to control cells. The results provide new insight into mechanisms of plant adaptation to saline stress as well as stress memory in metabolic level.

Purpose: The purpose of this study was to compare self-care behavior, diabetes-related stress and stress coping style among 3 blood glucose control groups (good, inadequate, and poor blood glucose control groups). Methods: Participants were 102 type 2 diabetic patients (good group: 41, inadequate group: 31, poor group: 30). Data were collected from Feb 19 to Mar 24, 2010 and were analyzed using Chi-square, Fisher's exact test and ANCOVA with SPSS/WIN 12.0. Results: Using ANCOVA with frequency of admission, and illness duration as covariates, significant differences were found among the 3 groups in self-care behavior (total score) and the exercise subscale. Using ANCOVA significant differences were found among 3 groups in diabetes-related stress (total score), emotional burden subscale and regimen distress subscale. Using ANCOVA no difference in stress coping was found among the 3 groups, but there was a significant difference in the problem-oriented coping subscale. Conclusions: Self-care behavior, diabetes-related stress, and stress coping style are factors influencing blood glucose control. The results of this study suggest that for improving blood glucose control, self care education program focused on diet and exercise in addition to stress management program for promoting problem oriented coping capability are recommended.

Purpose: This study was conducted to examine the effects of solution-focused group counseling on the general stress, stress response and coping in the delinquent juveniles. Method: The subjects consisted of a convenience samlple of 60 delinquent juveniles who had been placed under probation in Kwang-ju, and recruited from Oct., 2000 to Dec., 2000. Solution-focused group counseling was conducted for the experimental group once a week for 120 to 180 minutes for 6 week. The control group received no group session. For both groups the level of general stress, stress response and coping were measured before and after the experiment. Result: General stress significantly decreased in the experimental group and increased in the control group, but showed no significant difference between the two groups. Stress response decreased significantly in the experimental group and increased in the control group, but showed no significant difference between the two groups. The problem-focused coping significantly increased in the experimental group and decreased in the control group, and showed a significant difference between the two groups. The emotion-focused coping significantly decreased in the experimental group and increased in the control group, and showed no significant difference between the two groups. Conclusion: This study showed that solution-focused group-counselling has a positive effect on variables like the general stress, stress response, emotion-focused coping and problem-focused coping. Further study needs to be conducted to verify results.

Purpose: The purpose of this study was to examine the effects of phytoncide aromatherapy on stress, symptoms of stress and heart rate variability among nursing students. Methods: This study is a randomized control-group non-synchronized design. The experimental group (n=31) underwent phytoncide aromatherapy for 2 weeks, while the control group (n=31) received placebo therapy. The data were collected using self-administration questionnaires and measurement of heart rate variability (HRV) and analyzed using SPSS WIN 18.0 program. A p value <.05 was considered statistically significant. Results: Total score of stress, individual score of intrapersonal stress, and score of peripheral manifestations in symptoms of stress in the experimental group were significantly lower than those of the control group. All indices of HRV were significantly different between the two groups. LF norm and LF/HF ratio in the experimental group were significantly lower than those of the control group, and HF norm in the experimental group was significantly higher than that of in the control group. Conclusion: Based on these results, it can be suggested that phytoncide aromatherapy was effective in decreasing stress and peripheral manifestations of stress and changing in HRV among nursing students.

The purpose of this study was to examine the effect of supportive nursing on stress reaction of breast cancer patients undergoing chemotherapy. The nonequivalent control group pre-test/post-test design was used for this experimental study. The subjects were 32 patients who were receiving chemotherapy after mastectomies at K hospital in Taegu from June, 1994 to June 1995. Among 32 subjects, 16 were placed in the experimental group and 16 in the control group. The experimental and control groups were tested for general characteristics, trait anxiety, health locus of control, family support, state anxiety, hopelessness, physical stress, and anxiety behavior. Collected data was analized by means of a chisquare test and a t-test for the comparative analysis of the general characteristics and homogeneity of subjects. ANOVA, and MANOVA were used for testing the hypothesis. Reliability of the tools were analyzed using the Pearson Correlation coefficient. The results of this study were as follows : 1. The hypothesis : The stress reaction of the experimental group which took supportive nursing was lower than the stress reaction of the control group : this was supported statistically. The main variable influenced in stress reaction was hopelessness. Supportive nursing for breast cancer patients, who are receiving chemotherapy, was especially effective in the reduction of hopelessness compared to state anxiety, physical stress, and anxiety behavior. 2. An analysis of the difference on stress reaction, according to the frequency of supportive nursing between the control and experimental group, showed the level of hopelessness of the experimental group was lower than the control group after four supportive meeting sessions. But there was no statistical difference in state anxiety, physical stress, and anxiety behavior. In conclusion, this study supported utilization of supportive care as well as demonstrating the effectiveness of the System-Developmental Stress Model developed by Chrisman and Riehl-Sisca.

The present study was conducted to determine the effect of cold stress on broiler performance and ascites susceptibility. Male chicks were obtained from a commercial strain of broiler breeders. The trial was divided into two treatments (control and cold stress groups). Ascites was induced in broiler chickens in the trial by exposing the chickens to low temperature (Ta) and by supplying a pelleted diet. The two experimental treatments consisted of: 1) Control group, $33.3^{\circ}C$ the $1^{st}$ wk, $30.2^{\circ}C$ the $2^{nd}$ wk, and $27.5^{\circ}C$ the $3^{rd}$ wk. 2) Cold stress group, $29.0^{\circ}C$ the $1^{st}$ wk, $26.4^{\circ}C$ the $2^{nd}$ wk, and $23.1^{\circ}C$ the $3^{rd}$ wk. From the end of the $3^{rd}$ wk all broilers were reared to 6 wk of age at a constant temperature of $21^{\circ}C$. There was significant difference in live BW during wk 1 to 5. The control group was consistently the heaviest; however, at 6 wk of age, both groups weighed the same. Body weight gain up to 3 wk was significantly decreased by cold stress. During wk 3 and 6 the chicks in the cold stress group had greater BW gain compared with the chicks in the control group. There were significant differences in mortality due to ascites between the groups. During wk 3 and 6 the cold stress group exhibited the most ascites mortality (9.52%) when compared with the control group (1.90%). At 5 wk of age cold stress condition caused significant changes in packed cell volume (PCV), hemoglobin (Hb) and red blood cell counts (RBC). Right ventricle weight was significantly heavier in the cold stress group than the control. There were also significant differences in right ventricle/total ventricle (RV/TV) ratios at 5 wk. the right ventricle/total ventricle ratios in the cold stress group was higher (0.25) than the control group (0.20). It was concluded that, fast growth and cold temperatures are the primary triggers for ascites during commercial broiler production.

This study was conducted to investigate the effects of a weight control programs on BMI, nutrition knowledge, physical fitness and stress level of adult obese women. The subjects of this study were 36 adult obese women aged 30-65 years whose BMI were above $23\;kg/m^2$. The weight control program for obese women included nutritional education, exercise and cognitive behavioral therapy for 12 weeks. The BMI of the subjects was significantly decreased (p < 0.001) from $27.1\;kg/m^2$ to $26.4\;kg/m^2$ after the 12 weeks of the weight control program. In addition, the weight of body fat was significantly decreased (p < 0.001) and % body fat was significantly decreased (p < 0.05) from 35.4% to 34.9% after completion of the weight control program. In addition, nutritional knowledge (p < 0.001) and eating behavior scores (p < 0.01) were significantly increased. However, the food intake scores were not changed after the program. Stress levels of the adult obese women were significantly decreased (p < 0.001) from 85.63 to 66.88 and also obesity stress levels were significantly decreased (p < 0.01) after the weight control program. In the physical fitness levels of the subjects, muscle endurance (p < 0.05) and ability of balance (p < 0.01) were significantly improved after completion of the weight control program. There were positive significant correlations between general stress and obesity stress level (p < 0.05), and negative correlations between stress level and food intake score (p < 0.05). These results showed that the weight control program for adult obese women may be effectively used to improve weight reduction, physical fitness and stress levels.
