Objectives: Emotional support and a stress management program should be simultaneously provided to clients as effective preventive services for healthy behavioral change. This study was conducted to review various relaxation and meditation intervention methods and their applicability for a preventive service program. Methods and results: The author of this paper tried to find various relaxation and meditation programs through a literature review and program searching and to introduce them. The 'Relaxation Response' and 'Mindfulness Based Stress Reduction (MBSR)' are the most the widely used meditative programs in mainstream medical systems. Abdominal breathing, Progressive Musclular Relaxation (PMR), Relaxative Imagery, Autogenic Training (AT) and Biofeedback are other well-known techniques for relaxation and stress management. I have developed and implemented some programs using these methods. Relaxation and meditation classes for cancer patients and a meditation based stress coping workshop are examples of this program. Conclusions: Relaxation and meditation seem to be good and effective methods for primary, secondary and tertiary preventive service programs. Program development and standardization and further study are needed for more and wider use of the mindbody approach in the preventive service area of medicine.

In this paper, a new learning methodology for Kernel Methods is suggested that results in a sparse representation of kernel space from the training patterns for classification problems. Among the traditional algorithms of linear discriminant function(perceptron, relaxation, LMS(least mean squared), pseudoinverse), this paper shows that the relaxation procedure can obtain the maximum margin separating hyperplane of linearly separable pattern classification problem as SVM(Support Vector Machine) classifier does. The original relaxation method gives only the necessary condition of SV patterns. We suggest the sufficient condition to identify the SV patterns in the learning epochs. Experiment results show the new methods have the higher or equivalent performance compared to the conventional approach.

Twenty five cancer patients were assigned to two groups: The experimental group which received Progressive Muscle Relaxation (PMR) training and the control group without the training. Base line data for dependent variables -nausea and vomiting, state anxiety and symptom distress- were collected when the subjects of both groups received the first cycle chemotherapy. Then the experimental group was trained for PMR between the first and the second cycle chemotherapy. The same dependent variables were measured during the second cycle chemotherapy from the subjects. Results indicated that the PMR group showed no significant difference in severity of nausea and vomiting compared to the control group. Although the significance was not supported, the severity of nausea and vomiting in experimental group decreased while control group increased between the first and fifth day of the second cycle chemotherapy. The experimental group showed significantly less state anxiety during the second cycle than the control group (p＜0.01). Significantly low symptom distress was also reported in the experimental group compared to the control group(p<0.01). The result suggests that PMR training may be an effective procedure for helping cancer patients cope with the adverse effects of their chemotherapy.

Objective : The purpose of this research is to investigate the effects of Autogenic Training on autonomic nervous system for normal subjects with Heart Rate Variability(HRV). Then HRV of total subjects were analyzed by Sasang constitution, MBTI type and relaxation therapy experience. Method : Autogenic Training was applied on 39 subjects individually. Then HRV was examined each 5 minutes before and after Autogenic Training application. Results : 1. Mean HRV, SDNN, SDSD were significant different in HRV between before and after Autogenic Training application in total subjects. 2. SDNN, SDSD were significant different in HRV between before and after Autogenic Training application in Soeumin. Mean HRV, SDNN, SDSD were significant different in HRV between before and after Autogenic Training application in Taeeumin. Conclusion : The results suggest that Autogenic Training application have shown anti-stress effects. Autogenic Training application to Soeumin and Taeeumin have shown more anti -stress effects than application to Soyangin.

This paper a new simple PWM (Pulse Width Modulation) signal generation based on modified relaxation oscillator is introduced. Its advantages of the proposed principle are that the precise PWM signal can be easily achieved with a high frequency range up to several megahertz and a low-voltage power supply. The proposed circuit can accept either voltage or current modulating signal. It is very suitable for developing into Integrated Circuits (ICs) form in communication applications. The simulation and experimental results are also depicted, they shown good agreement with theoretical anticipation.

Biofeedback training is one of physiological self control methods for patients who has psychological problem and rehabilitational problem. It has been used to control blood pressure, heart rate, peripheral temperature, respiration, electromyography (ENG), and other biological signals-ENG, respiration, heat rate, peripheral temperature, skin conductance level-was developed in house. We applied this system to alcohol dependent patients to perform biofeedback training. In this experiment, the relaxation biofeedback training for alcohol dependent patient was carried out and the tension state for the change of biological signals were estimated using the fuzzy theory after relaxation biofeenback training. Eight alcohol dependent patients were agreed to participate in this experiment. Result showed that 1) the tension degree of patients were higher than the tension degree of normal subject. 2) The tension degree of patients were decreased as the training numbers were increased.

The purpose of this study is to examine the effect of voice improvement when vocal training, which relaxes the vocal contact, is applied to children with vocal nodules. Subjects included 20 5- to 12-year-old boys with vocal nodules in Otolaryngology and for whom voice therapy had been advised. The vocal therapy was conducted for 40 minutes per a week for a total of eight times. Results were evaluated by videostroboscopy, auditory-perceptual evaluation of GRBAS Scale, aerodynamic test, and acoustic analysis before and after therapy. As a result, first, the size of vocal nodules was reduced and the unstable pattern of vocal contact was improved. Glottic closure was increased and Phase symmetry was decreased during vocal vibration. Mucosal wave was increased and muscle tension of the larynx was reduced. Second, auditory-perceptual evaluation showed that subjects' overall quality of voice improved. GRBAS Scale Evaluation showed that the characteristics of the subjects' voice which were rough, breathy, and strained and breathy were reduced after therapy. Third, the measurements of acoustic parameters showed a statistically significant improvement. The fundamental frequency of the subejects' voice was increased and values of Jitter and Shimmer, NHR, [H1-H2] decreased. Fourth, the maximum phonation time of children was increased. These results imply that vocal relaxation training conducted in this study has a very positive effect to improve the voice of children with vocal nodules.

Psychogenic neurological conditions account for 1% to 9% of admissions at neurological unit. They are considered manifestations of underlying psychiatry disorders such as somatoform disorders and factitious disorders or malingering. Diagnosis for psychogenic tremor is difficult because mimic tremor is occurred at the secondary of the organic disorders or coexist in a patient with tremors of organic origin. A patient in this case report was diagnosed as psychogenic tremor, and she also complained the severe anger. A patient did not improved with the chemical medication for a long time. The patient received relaxation training, herbal medication and acupuncture for 20 days and showed short-term alleviation on tremor and decreased anger problem and other somatic problems.

PURPOSE: This study investigated the immediate effects of gluteus medius strengthening training and relaxation therapy on the static balance, muscle strength asymmetry, and proprioception. METHODS: In this research, 38 healthy adults were assigned randomly to strengthening groups (SG) and relaxation groups (RG). The static balance, muscle strength asymmetry, and proprioception were measured as a pre-measurement. The same measurements were performed after the intervention and follow-up. An independent sample t-test was used to compare each group, and one-way repeated ANOVA was used to compare the changes within the group. RESULTS: In the static balance, the comparison between groups SG was more significant than RG, and only SG showed significant differences in the intra-group comparisons. There was no significant difference in muscle strength asymmetry between SG and RG. On the other hand, the comparison within the group revealed only SG to be significant. In proprioception, SG produced more significant results than RG, and only SG had significant values in the within-group comparison. CONCLUSION: Strengthening training affects the changes in static balance, muscle strength asymmetry, and proprioception.
