Objective: Constraint induced aphasia therapy (CIAT) is a more intensive form of language treatment for aphasia as compared to traditional treatments. This study examined whether there are differences in cortisol stress levels between the two methods of aphasia treatment as well as effects on language skills. Design: Randomized controlled trial. Methods: A total of 20 participants with expressive aphasia were randomly placed into one of the two treatment groups. The CIAT group received 10 days of intensive treatment over two weeks. The traditional therapy group received 6 days of treatment over 2 weeks. All participants in each group provided salivary cortisol samples before treatment, at the mid-point of treatment, and at the conclusion of treatment. Language skills were assessed before treatment and at the conclusion of treatment. Results: A significantly higher proportion of individuals in the CIAT treatment group had increased salivary cortisol stress levels when compared to the traditional treatment group at the mid-point of the program (80% versus 30% respectively, p<0.05). There was no significant difference in the proportion of individuals with increased cortisol stress by the end of the treatment. Language scores for word repetition and overall aphasia quotient significantly improved for the CIAT group when compared to the traditional group (p<0.05). Conclusions: The CIAT treatment appears to initially create increased psychophysiological stress as compared to the traditional treatment. In spite of the initial increases in psychophysiological stress, participants appear to become conditioned to the challenge and ultimately have enhanced benefit from CIAT treatment.

The study examines the effects of local environmental factors on stress among young and senior single-person households. We analyzed the '2019 Community Health Survey' by employing logistic regression analysis. The empirical results are as follows: First, there are greater differences in stress factors between young single-and multi-person households than senior single-and multi-person households; Second, stress among young single-person households was mainly influenced by physical environmental factors while stress among senior single-person households was influenced by both physical and social environmental factors. The results suggest that customized support at the local level is necessary in consideration of age-specific characteristics and stress vulnerabilities when promoting policies for the promotion of mental health among single-person households.

In this paper, we propose a 2D-FE model in single impact with combined physical factors to obtain a unique residual stress by shot peening. Applied physical parameters consist of elastic-plastic deformation of shot ball, material damping coefficients, strain rate, dynamic friction coefficients. As a kinematical parameter, there is impact velocity. Single impact FE model consists of 2D axisymmetric elements. The FE model with combined factors showed converged and unique distributions of surface stress, maximum compressive residual stress and deformation depth. Further, in contrast to the FE models with rigid shot and elastic deformable shot, FE model with plastic deformable shot produces residual stresses very close to experimental solutions by X-ray diffraction. We therefore validated the 2D FE model with combined peening factors and plastic deformable shot. This FE model will be a base of the 3D FE model for residual stresses by multi-impact shot peening.

Purpose: The purpose of this study was to determine the stress, depression, and fetal attachment of pregnant women who underwent infertility treatment, and to identify factors associated with fetal attachment. Methods: As a correlation survey design, data were collected from 136 pregnant women who underwent infertility treatment. Data were analyzed using ${\chi}^2$-test, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: Stress, depression, and fetal attachment averaged $3.01{\pm}0.60$ (range of scale 1~5), $10.02{\pm}6.51$ (out of a possible 63), and $3.64{\pm}0.55$ (range of scale 1~5), respectively. Level of fetal attachment was higher when mother's age was less than 35, having other children, and having prenatal education experience. Lower score of depression and client's age less than 35 were significant factors affecting fetal attachment. Conclusion: Infertility is a life-affecting trauma for the individual, and personal and social changes due to infertility cause physical and psychological difficulties even after a successful pregnancy with infertility treatment. Therefore, prenatal management programs need to be developed giving consideration to the emotional and physical changes in order to promote physical and psychological stability in the women pregnant following infertility treatment.

Purpose: This study was done to identify the influence of workplace violence on anger and post traumatic stress disorder among nurses. Methods: The research design for this study was a descriptive survey design using a random sampling. Data collection was done using self-questionnaire with 477 nurses. The collected data were analyzed by descriptive statistics, ${\chi}^2$-test and logistics regression. Results: The incidences of total violence, verbal, physical, and sexual violence were 31.2%, 28.7%, 6.3%, 3.6% of the nurses, respectively. Anger was significantly associated with verbal violence (OR: 2.34, CI: 1.40~3.91) and physical violence (OR:4.85 CI: 1.67~14.13). Post traumatic stress disorder was significantly associated with verbal violence (OR: 15.99, CI: 9.58~26.69) and physical violence (OR: 5.37, CI: 1.66~17.40). Conclusion: To promote psychological health in nurses, there is a need to develop prevention programs to decrease workplace violence and to develop programs supporting psychological aspects of verbal violence that nurses experience.

The purpose of this study was to identify the effect of Korean traditional dance exercise on physical health (BMI; body mass index, BP; blood pressure, VC; vital capacity, TC; total cholesterol, HDL; high-density lipoprotein, TG; triglyceride), self-efficacy and stress in elderly women. A quasi-experimental research design(one group pretest and posttest) was used for this study. Participants were recruited in a metropolitan city and a total of 43 community dwelling elderly women completed the 12-week Korean traditional dance exercise program. Descriptive statistics and paired t-tests were used in the data analysis by SPSS/WIN 12.0. After the Korean traditional dance exercise program there was a significant difference in BMI, VC, TC, HDL, stress and self-efficacy. There were, however, no significant changes in BP, and TG level after completing this program. This study suggests that Korean traditional dance exercise may be one of the effective nursing interventions for elderly women.

Fighter pilot's ability to maintain both mental and physical capabilities in highly stressful situations is important for aviation safety as well as mission performance because pilot may confront frequently unexpected physical and psychological stimulation. Cumulative psychological stress and physical fatigue can be causes of mood distortion, declined alertness, and can lead to reduction of combat capability. We have investigated bio-signals and performance tests to monitor stress and fatigue levels, and developed a system to evaluate aviation mission suitability before flight. This study elucidated that stress and fatigue level of pilot can be monitored by psychomotor cognitive test(PCT) and heart rate variability(HRV), and that the best of reference for aviation mission suitability was confidential interval obtained from cumulative data of individuals. The system to evaluate aviation mission suitability was constructed with measuring part with PCT and HRV and control part with DB and algorithm.

Background: The myofascial release technique is known to be an effective technique for increasing posterior fascia flexibility in short hamstring syndrome (SHS) subjects. But therapeutic mechanism of myofascial relaxation remains unclear. Recently, the theory of autonomic nervous system domination has been raised, however, a proper study to test the theory has not been conducted. Objectives: To investigate whether the application of the myofascial release technique can induce changes in the autonomic nervous system and affect the secretion of stress hormones and myofascial relaxation. Design: Quasi-experimental study. Methods: Twenty-four subjects with SHS were randomly divided into two groups. In the experimental group, the suboccipital muscle inhibition (SMI) technique was applied to the subjects for 4 min in supine position, and in the control group, the subjects were lying in the supine position only. A forward flexion distance (FFD) was conducted, blood pressure, heart rate, and cortisol levels were measured before and after the intervention and 30 min after intervention to determine myofascial relaxation and stress hormone levels. The evaluation was conducted separately in blind by an evaluator. Results: A FFD decreased in the experimental group, no change in cortisol was observed. On the contrary, a decrease in cortisol appeared in the control group after 30 minutes. Conclusion: The myofascial release technique is an effective treatment to increase the range of motion through posterior superior myofascial chain, but there is no evidence that myofascial release technique can control the autonomic nervous system.

To determine the preventive effect of Samulanshintang (SA) on stress, we investigated the physiological change of rats which were applied immobilization stress. For immobilization stress, rats were placed in restrainer for 12 hours a day for 3 days. During application of stress, body weight of rats was measured. After sacrifice, 4 organs were taken for measurement of organ weight. Brain was homogenated and its catecholamine and serotonin contents were measured with HPLC. In our study, stress mainly induced increase of concentration of neurotransmitters in brain without other significant physical change of rats. SA inhibited stress induced changes of neurotransmitter content in brain.
