This study was done in order to help alleviate or prevent the anxiety resulting from cardiac catheterization among adult patients. This goal may be re-ached through providing relaxation techenique to the patients. Such an informativeness would make it possible to establish a basis for comprehensive nursing intervention. The results of this study are summarized as fellows: 1. The first hypothesis:“The experimental group with relaxation informativeness will have less score of state anxiety level before cardiac catheterization than the control group without relaxation informativeness”was accepted. (t=3.72, p=.001). 2. The second hypothesis: “The experimental group with relaxation technique informativeness will have less score of distress level during the procedure than the control group without relaxation technique informativeness”was accepted. (t=2.36, p=.023) 3. Additional analysis; It is seen that most cardiac patients were satisfied with precardiac catheterization procedure information provided by medical teams. (experimental group: 90%, control group: 85%) The relaxation technique informativeness contributed to the decrease of anxiety level. Patients showed interest in reusing the relaxation technique informativeness in the event of further need. In conclusion, the researcher thinks that it is necessary that nurses provide Patients with relaxation technique to reduce the anxiety level with cardiac catheterigation. This will enable them to practice effective comprehensive nursing.

This Study is aimed at showing the effect of relaxation technique on reduction of anxiety of nursing students in the first clinical practice. The samples of this research were eighty fresh-man students of Dong San Junior College of Nursing. Of them thirty-eight were experimental group and remaining forty-two were control group. This study has been conducted from October 14 to 22, 1985. Subjects in all two groups had measured their trait anxiety, after then, the researcher carried out Byun's relaxation technique with experimental group every other day After the experimental period, subjects in all two groups had measured their state anxiety. The tools of this study were two kinds: Spielberg, Gorsuch & Lushene's STAI, and Byun's relaxation technique. To test the statistical difference in the subjects' trait anxiety, score of lecture in pre-clinical practice and score of practice pre-clinical practice, t-test was performed. To verify the hypotheses, ANCOVA was performed. Results of this study were as follows: The main hypothesis that the nursing students who use relaxation technique will have less degree of anxiety in the first clinical practice than the nursing students who don't use relaxation technique was accepted (P<.005). Conclusively, the researcher thinks that it is necessary that nursing students were prepared with relaxation technique to reduce anxiety in their first clinical practice.

Relaxation technique is an independent nursing intervention used in various stressful situations. The concept of relaxation must be explored for the meaning given by the people in their traditional thought and philosophy. Korean relaxation technique, wanting to become culturally acceptable and effective, is learning to recognize and develop Korean concepts, experiences, and musics of relaxation. This study was aimed at discovering Korean concepts, experiences and musics of relaxation and contributing the development of the relaxation technique for Korean people. The subjects were 59 mursing students, 39 hospitalized patients, 61 housewives, 21 rural residents and 16 researchers. Data were collected from September 4th to October 24th, 1991 by interviews or questionaires. The data analysis was done by qualitative research method, and validity assured by conformation of the concept and category by 2nursing scientists who had written a Master's thesis on the relaxation technique. The results of the study were summerized as follows; 1. The meaning of the relaxation concept; From 298 statements, 107 concepts were extracted and then 5 categories "Physical domain", "Psychological domain", "Complex domain", "Situation", and "environment" were organized. 'Don't have discomforts, 'don't have muscle tension', 'don't have energy(him in Korean)', 'don't have activities' subcategories were included in "Physical domain". 'Don't have anxiey', 'feel good', 'emotional stability', 'don't have wordly thoughts', 'feel one's brain muddled', 'loss of desire' subcategories were included in "physical domain" 'Comfort body and mind', 'don't have tension of body and mind', 'be sagged' 'liveliness of thoughts' subcategories were included in "Complex domain". 'Rest', 'sleep', 'others' subcategories were included in "Situation domain". And 'quite environment' & 'comfortable environment' subcategories were included in "Environmental domain". 2. The experiences of the relaxation; From 151 statements, 59 experiences were extracted. And then 9 categories-at rest after physical activities, after problem solving, fancy, bathing in the bed, situation, rest, particular time, others-were organized. 3. The musics of the relaxation; From 229 statements, 108 musics were extracted. and the 9 categories- Western classical music, semi classical music, Korean song, Korean popular classical music, song, western popular sonhg, hymn, characteristics of music, others - were organized. In conclusion, There are some differences between Korean concepts, experiences and musics of relasation and western concepts, experiences and musics of relaxation.

Postoperative pain is one of the most frequently occurred pain in hospitals, but it has been underestimated because it is only a part of postoperative physiological Process and may disappear in time. It is necessary that nurses me the relaxation technique, planning and implementing by themselves independently, to reduce this postoperative pain. This study is aimed at showing the effect of relaxation technique on reduction of postoperative pain, and exploring the factors influencing postoperative. pain Fifty-seven patients with abdominal surgery who admitted in attacked D Medical Center to K University in Daegu have been studied. Of them twenty-nine were experimental group and the remaining twenty-eight were control group. This study has been conducted for collecting data through interviews and observation from August 23 to October 24, 1984. The tools of this study were two kinds: Postoperative Pain Scale is obtained from a review of references by the researcher, and relaxation technique, designed to use postoperative setting adequately, is also obtained from a review of references by the researcher. After confiriming no significant differences between the two groups, the hypotheses were statistically verified by x²-test, t-test, and pearson Correlation Coefficient. The results of this study are summerized as follows; ＊ The nam hypothesis that the experimental group who use relaxation technique will have less degree of postoperative pain than the control group who don't use relaxation technique is devided into three sub-hypotheses. 1. The first sub-hypothesis that the experimental group will have less score of postoperative pain than control group was accepted (t=7.810, p <.01). Even with controlling pain threshold, showing difference in some degree between the two groups, the experimental group has less score of postoperative pain than the control group. Therefore this confirms the acceptance of the first sub-hypothesis more strongly. 2. The second sub-hypothesis that the expermental group will have less frequency of analgesics than the control group is accepted (x²=9.85, p <.01). 3. The third sub-hypothesis that the experimental group will have less variation of pulse, respiration, and blood pressure between pre End post operative periods than the control group is rejected. So this hypothesis is reverified through comparing the variation of pulse, respiration, and blood pressure between pre and post changing Position to measure the pure effect of relaxation technique. pulse and respiration is significantly lowered in the experimental group (t=7.209, p<.01, t=3.473, p<.01), but systolic and diastolic blood pressure is not different significantly between the two groups (t= 1.309, p＞.05, t=1. 727 p>.05). Therefore the third sub-hypothesis is partially accepted. Conclusively, the researcher thinks that it is necessary that nurses should provide patients with relaxation technique to reduce postoperative pain, and to increase independence of nursing.

It has been shown that the distribution of relaxation times, H(ln $\tau$), in semi-logarithmic time scale can easily be calculated numerically from the derivative of the relaxation function in semilogarithmic scale. In that, ln$\tau$, the abscissa, is divided into N different segments of equal size, then H is considered to be a linear function of ln $\tau$within each segment. The technique has been applied to a Williams-Watts function as well as to the relaxation function obtained by photon correlation spectroscopy from atactic polystyrene glass. It has been demonstrated that the relaxation functions can be precisely reproduced from the calculated distribution functions.

The relaxation response is a state of profound rest, creates physiological responses directly opposite to the stress response. The relaxation response can be used to counteract the harmful effects of stress. The relaxation response can be elicited by a number of techniques such as diaphragmatic breathing, meditation, progressive muscle relaxation, autogenic training, biofeedback, etc. These relaxation methods in any mental or physical conditions associated with distress and even in normal people have useful benefits for stress control and health enhancement. These relaxation techniques are but one part of a comprehensive stress management program, through regular and continuous practice appropriate for each person, they will make an effective role in stress management. In this review, author reviewed how to practically use meditation, progressive muscle relaxation and autogenic training, in more detail. In the treatment of various stress-related disease, especially in psychiatric disorders, the relaxation technique may be a useful complement to conventional treatment and serves as an intervention between stress and disease.

Background: The purpose of this study was to investigate the effect of various relaxation techniques on various dysfunction problems caused by shortening of the sagittal muscles. Method: The subjects were 44(18 males, 26 females). The subjects were composed of 3 groups. The experimental group consisted of 14 patients with proprioceptive neuromuscular facilitation stretching (PNF) technique, control group A 15 patients with self myofacial release (SMR) ball exercise, and control group B with 15 patients with Sling exercise. After 3 weeks of relaxation on the hamstring muscle, the length of the hamstring muscle before and after the intervention was compared. Results: The results of relaxation exercise of the snake muscles applied to passive PNF group, SMR ball group, and Sling relaxation group are as follows. 1. In the passive PNF group, the muscle length of the hamstring muscle was significantly increased after the intervention. 2. The muscle length of the hamstring muscle was significantly increased after the intervention in the SMR ball group. 3. Sling relaxation group significantly increased the muscle length of the hamstring muscle after sling exercise intervention. 4. Passive PNF group showed the greatest change in muscle length before and after intervention than SMR ball group and Sling relaxation group. Conclusion: Passive PNF relaxation therapy, SMR ball relaxation therapy, and Sling relaxation therapy applied to the hamstring muscle were effective in increasing muscle length of the hamstring muscle. PNF relaxation therapy showed the most significant effect after 3 weeks intervention.

We study the incomprssible Navier Stokes equations for the flow inside contraction geometry. The governing equations are expressed in the vorticity-stream function formulations. A rectangular computational domain is arised by elliptic grid generation technique. The numerical solution is based on a technique of automatic numerical generation of acurvilinear coordinate system by transforming the governing equation into computational plane. The transformed equations are approximated using central differences and solved simultaneously by successive over relaxation iteration. The time dependent of the vorticity equation solved by using explicit marching procedure. We will apply the technique on several irregular-shapes.
