Purpose: Purpose of this study was to examine the effects of the Mindfulness Meditation program on perceived stress, ways of coping, salivary cortisol level, and psychological stress response in patients with breast cancer. Methods: This was a quasiexperimental study with a non-equivalent control group pre-post test design. Participants in this study were 50 patients who had completed breast cancer treatment (experimental group, 25, control group, 25). The experimental group received the Mindfulness Meditation program for 3 hours/session/ week for 8 weeks. Data were analyzed using $X^2$-test and t-test for subject homogeneity verification, and ANCOVA to examine the hypotheses. Results: The experimental group had significantly lower scores for perceived stress, emotional focused coping, salivary cortisol level, and psychological stress response compared to the control group. However, no significant differences were found between two groups for the scores on problem focused stress coping. Conclusion: According to the results, the Mindfulness Meditation program was useful for decreasing perceived stress, emotional focused coping, salivary cortisol level, and psychological stress response. Therefore, this program is an effective nursing intervention to decrease stress in patients with breast cancer.

To investigate effects of starvation on physiological changes, stress response, and survival of cobitid loach (Misgurnus anguillicaudatus) exposed to sodium nitrite (NaNO₂), a 4-week experiment was conducted. Fewer fish survived in the starved group than those in the fed group during the experiment. Starvation resulted in growth retardation, leading to differences in body length and body depth between fed and starved groups. The fed gorup continued to grow and remained in good condition. Blood chemical analysis (plasma cortisol and glucose) showed significant differences in stress response to nitrite exposure between fed and starved groups (p < 0.05). These results suggest that all parameters employed in this study to assess effects of starvation with NaNO₂ stress are useful information for researching nutritional status in cobitid loach.

Purpose: This study was performed to investigate the effects of aromatherapy on headache, stress and immune response of students with tension-type headache. Method: This study employed a two-group pre-post test study design. Data was collected from 44 subjects. Twenty-two subjects were assigned to the experimental group and received aromatherapy massage every other day for 3 weeks, but the other 22 subjects were in the control group and did not receive any intervention. Experiment had been conducted from Apr. 9 through Aug. 25, 2001 and intensity of headache, stress response (serum cortisol, life stress) and immune response(T-cell and natural killer cell ratio) were measured in the course of aromatherapy for both experimental group and control group. Data were analyzed by using $X^2$-test, t-test, Paired t-test and repeated measures ANOVA. Result: Headache scores, serum cortisol levels and life stress scores were significantly decreased in the experimental group after treatment compared to the control group. Conclusion: These findings is suggested that the aromatherapy could be an effective nursing intervention in relaxing and relieving the pain caused by tension-type headache for students.

In order to improve self-management of elderly hypertensives in this study, the researcher examined the effect of blood pressure regulation by an abdominal relaxed breathing training which regulates physical response to stress and lessens the activity of the sympathetic nerve. Method: A quasi-experimental pre-test and post-test design was used. Thirty elderly hypertensive patient ; Sixteen in the abdominal breathing group and fourteen in the control group participated in this study. The abdominal relaxed breathing training consisted of eight sessions twice a week for four weeks. There was no intervention for the control group. Result: 1. There was a significant decrease in systolic and diastolic blood pressure between the experimental group and control group over three different times, and interaction by groups and over time. 2. There was no significant difference in the level of total stress response, physical stress response, behavioral-cognitive stress response between the experimental group and control group over three different times, and interaction by groups and over time. Conclusion: Findings indicate that this study will contribute to develop nursing strategies for the regulation of blood pressure for the elderly, which is easy for the elderly to learn as a nonpharmacologic approach.

The objective of this study is to evaluate the liquefaction cyclic shear stress ratio considering the soil uncertainty. In this study, the probabilistic ground response analysis and the cyclic shear stress ratio analysis for the liquefaction potential evaluation are performed considering the soil variability. The statistical properties of input ground parameters were analyzed to investigate the parameters affecting the seismic response analysis. The Probabilistic analysis was carried out by Monte Carlo Simulation method. The ground response analysis was performed considering the soil variability and the probability distribution characteristics of the ground acceleration. The probability distribution of the peak ground acceleration by seismic characteristics was presented. The differences of liquefaction shear stress ratio results according to soil variability were compared and analyzed. The maximum acceleration of the ground by the deterministic method was analyzed to be overestimation of the ground amplification phenomenon. Also, the shear stress ratio was overestimated.

Thioltransferase, also known as glutaredoxin, is an enzyme that catalyzes the reduction of a variety of disulfide compounds. In Schizosaccharomyces pombe, two thioltransferases were reported and the cDNA of one of the thioltransferases (thioltransferase-1) was cloned. Using a Northern blot assay, we investigated the thioltransferase transcription in response to various stress conditions. When the culture was shifted to a high temperature, the thioltransferases transcription was not significantly changed compared to the unshifted $30^{\circ}C$ culture. Treatment of zinc chloride to exponentially-growing cells remarkably increased the thioltransferase transcription, whereas the treatment of mercury chloride greatly reduced the transcription. Treatment of hydrogen peroxide and cadmium chloride caused no significant effects on the transcription of the thioltransferase. These results suggest that the transcription of thioltransferase-1 in S. pombe is induced in response to metal stress that is caused by zinc chloride, but not in response to heat stress or oxidative stress that is caused by hydrogen peroxide.

This study was undertaken to assess the effect of sound stress on humoral and cellular immune responses to thymus-dependent and independent antigens in mice. After mice were exposed to 4 hr daily sound stessors(83㏈) for 4 days before or after immunization, the primary and / or secondary immune response to sheep red blood cells(SRBC), polyvinylpyrroridone(PVP) or picry1 chloride(TNCB) were assayed. When mice were exposed to sound stressor before or after immunization, delayed-type hypersensitivity reaction and contact sensitivity to TNCB was remarkably depressed compared with those of the unstressed control mice. However, the primary and secondary hemagglutinin response of the stresed mice to SRBC showed a pronounced increase compared with that of the unstressed mice, In contrast to antibody response to SRBC, the primary antibody response of the stressed mic to PVP was almost not detected. surprisingly, the secondary antibody response to PVP of the mice receiving the secondary sound stress was markedly increased when the immune-depressed mice received the secondary immunization with PVP at 46 days after the primary immunization. The susceptibility of mice to intraven-oulsy infected Candida albicans was not changed by the sound stress.

Purpose: This study was to evaluate the effects of a comprehensive life style modification program on glycemic control and stress response in type 2 diabetes. Method: The participants(n=34) with type 2 diabetes were divided into either a usual care(control) or treatment(experimental) group. The experimental group(n=21) received a program that was based on a comprehensive life style modification protocol at a weekly meeting for 16 weeks. They also participated in individually prescribed exercise and diet along with stress management and self monitoring. The participants were followed for 6 months, during which postprandial glucose, HbA$_{1C]$, and stress response inventory were measured. Result: The experimental group showed a significant lower postprandial glucose and stress response compared to those of the control group. However, there was no significant change in the HbA$_{1C]$ value in either group. Conclusions: These results suggest that a type 2 diabetes comprehensive lifestyle modification program may lead to clinical improvement in glycemic control and reduce the stress response.
