The purpose of this study was to explore the effects of hand reflexology on the physiological.emotional responses and immunity of the patients with chronic illness. This study looked specifically at patients with chronic renal failure(CRF) and cancer patients. Method: This study was designed as a quasi-experimental nonequivalent control group pre and post test. Subjects were 54 patients who received dialysis and chemotherapy in one hospital. Thirty-one patients were assigned to the experimental group and 23 to the control group. The hand reflexology was applied to both hands of the experiment group for ten minutes each time, 5 times during three days. For data collection, physiological lab levels, immune cells of blood and questionnaires for emotional responses were measured before and after the program. Result: BT of the experiment group was decreased significantly on both of the 1st and the 5th application. PR & BP were decreased significantly on the 1st times, but not 5th times. Hb levels of the experimental group were significantly increased. And emotional responses, vigor and mood scores of the experiment group were significantly increased. B cell & CD19 were increased significantly on the experiment group. Suppressor T cell and NK cell showed significant decrease after the program, but no significant differences between the groups. Conclusion: We have found that the hand reflexology helps the chronic patients to improve physiological.emotional responses and the immune reaction. Through this result, the hand reflexology is effective as a intervention of psychoneuroimmunologic function.

The purpose of this study was to verify the effects of Yoga exercise as one way of the nursing intervention on stress and health status. This study was a quasi-experimental design with a non-equivalent control group pretest and posttest design. The study subjects were clinical nurses at K University hospital, in J city. Fifty one nurses were selected with 26 to a experimental group and 25 to a control group. The study data were collected from November, 2002 to January, 2003. During this period Yoga exercise was given to experimental group three times per week(one hour every time) for twelve weeks and no program was given to control group. The degree of general stress, job stress, health perception and health status was measured before and after experiment. The data were analyzed using SAS 8.1 program to obtain chi-square, paired, unpaired t-test. The results of this study are as follows. 1. After the experiment, the degree of general stress increased (t=-3.61, p=0.001) in experimental group, but in control group. There was significant difference between two groups (t=-2.10, p=0.041). However there was no significant difference in job stress between two groups and in each group (p=0.001), 2. After the experiment, the degree of health perception in experimental group increased (t=2.13, p=0.043) in control group. There was no significant difference between two groups. Health status in experimental group increased (t=3.14, 0.004) but in control group after the experiment. There was no significant difference between two groups. From the results, we are convinced that Yoga exercise is the nursing intervention that could decrease stress and promote health status in clinical nurses. Therefore Yoga exercise could be largely applied as one way of health care for nurses.

The experiment of rip current at successive ends of breaking wave crests was conducted in a laboratory wave basin, and its time-varying evolution according to incident wave durations was observed by using ortho-rectified images. The experiment utilized the generation of a quasi nodal line of the honeycomb-pattern waves (i.e., intersecting wave trains) formed by out-of-phase motion of two piston-type wave makers arranged in the transverse direction, instead of the original honeycomb pattern waves which are generated when two wave trains propagate with slightly different wave directions. The particle moving distance and velocity caused by the rip current were measured by using the particle tracking technique. As a result, the rip current was survived for a while even without incident waves after its generation due to several successive ends of wave crests, and it moved the particles further out to sea.

The experiment of unsteady rip current generated at the successive ends of breaking wave crests of honeycomb pattern waves was conducted in a laboratory wave basin, and its time-varying evolution was observed by using ortho-rectified images. The present experiment utilized the generation of a quasi nodal line of the honeycomb-pattern waves formed by out-of-phase motion of two piston-type wavemakers arranged in the transverse direction, instead of the original honeycomb pattern waves which are generated when two wave trains propagate with slightly different wave directions. The velocities of rip current were measured by using the LSPIV (Large-Scale Particle Image Velocimetry) technique. As a result, the unsteady rip current was generated between successive ends of wave crests, and evolved with its shear fluctuations in this experiment. Also, the time series of LSPIV velocity of the unsteady rip current showd its short component due to waves and its long component due to wave-induced currents.

Objectives : This study is a quasi-experiment with a pre-post design and a nonequivalent control group performed from May 1 to June 2, 2013 to verify the effects of a simulation based education program on nursing students' self-confidence, and clinical performance ability. Methods : The subjects of the study were a total of 60 students in their fourth year of a nursing program at a university located in G city and they were assigned to an experimental group of 30 students and a control group of 30 students by convenience sampling. Results : After being offered education, self-confidence, and clinical performance ability were significantly more improved than before in each group. In the comparison of the two groups, the self-confidence (t=3.00, p=.004) and clinical performance ability(t=3.14, p=.003) of the experiment group were significantly higher than those of the control group. Conclusions : The results indicated that instructional methods using a simulation-based emergency care program should be adopted maximize the effects of advanced cardiopulmonary life support education.

Recently the ab initio effective valence shell Hamiltonian method $H^v$ has been extended to treat spin-orbit coupling in atoms or molecules. The quasidegenerate many-body perturbation theory based $H^v$ method has an advantage of determining the spin-orbit coupling energies of all valence states for both the neutral species and its ions with a similar accuracy from a single computation of the effective spin-orbit coupling operator. The new spin-orbit $H^v$ method is applied to calculating the fine structure splittings of the valence states of SiH, $SiH^+$, and $SiH^{2+}$ not only to assess the accuracy of the method but also to investigate the spin-orbit interaction of highly excited states of SiH species. The computed spin-orbit splittings for ground states are in good agreement with experiment and the few available ab initio computations. The ordering of fine structure levels of the bound and quasi-bound spin-orbit coupled valence states of SiH and its ions, for which neither experiment nor theory is available, is predicted.

Purpose: The purpose of this study is to provide a disease management, nutrition education, and group exercise program for three months to the moderately frail elderly whose physical functions have deteriorated, and to investigate its effects in order to develop an intervention program. Methods: As a quasi-experiment, this study was conducted based on non-equivalence studies designed as a similar experiment. The milk intake group and calcium intake group participated in the disease education, individual nutrition education, and group exercise program for three months, and the control group was visited once in the three months by a nurse who provided disease education, nutrition education, and oral instruction of exercise, and asked them to exercise on their own every day. For the data analysis, ${\chi}^2$-test, ANOVA and $Scheff{\acute{e}}$ test were used. Results: After three months of intervention, there was a significant difference in the frailty level (p=.029) and bone density (p=.001) between the groups. Conclusion: The comprehensive intervention program had an effect on the bone density and the frailty level of the socially-vulnerable and moderately frail elderly, suggesting that the program can be used as a nursing intervention to prevent functional deterioration and damage of the moderately frail elderly.

Purpose: The present study is a quasi-experimental research for examining the effects of imagery on stress, anxiety and immune cells in acute leukemia patients receiving chemotherapy and utilizing the therapy for their self control and stress management. Methods: The subjects were 60 patients who were diagnosed with acute leukemia and scheduled to receive chemotherapy at A hospital in Seoul during the period from November 2006 to March 2007. After the start of chemotherapy, the experimental group received imagery for 4 weeks, three sessions a week, so a total of 12 sessions and 156 minutes. Results: The decrease of stress was larger in the experimental group than in the control group. Systolic blood pressure decreased significantly more in the experimental group than in the control group. In the experimental group, state anxiety decreased significantly in the 2nd week of the experiment and after the final stage of the experiment. The total number of white blood cells, and the absolute number of neutrophils and lymphocytes were showing significant differences between the time points. Conclusion: Imagery is an effective intervention for reducing stress and state anxiety and stabilizing blood pressure in acute leukemia patients receiving chemotherapy.

Purpose: This study was to evaluate effect of an educational program based upon experiment for smoking prevention in middle school students. Method: A quasi-experimental design was used. The participants were 107 middle school students (53 in the experimental group, 54 in the control group). Students in the experimental group participated in three 45-minute educational programs over a period of 2 weeks. The dependent variables were measured before and 2 & 4 weeks after the treatment. The data were analyzed using $x^2$ test, Fisher's exact test, t-test, and repeated measures ANOVA. SPSS was used to aid analysis. Results: 1) The experimental group showed higher levels of knowledge of smoking prevention compared to the control group. However this program did not affect their attitude towards smoking. 2) There was a higher possibility of smoking in the future among the students who had smoked than those who had not. 3) The majority (84.9%) of the experimental group said that the program was effective. Conclusion: Knowledge of smoking for the experimental group was increased, so it is assumed that the program itself had a positive effect on the students. To change attitudes regarding smoking, smoking prevention programs need to be conducted repeatedly, not just temporarily.

Background: Walking is a complex activity. The main components of walking include balance, coordination, and symmetrical posture. The characteristics of walking patterns of stroke patients include slow walking, measured by gait cycle and walking speed. This is an important factor that reflects post-stroke quality of life and walking ability. Objective: This study aimed to examine the effect of deep lumbar muscle stabilization exercise on the spatiotemporal walking ability of stroke patients. Design: Quasi-experial study Methods: The experiment was conducted 5 times per week for 4 weeks, with 30 minutes per session, on 10 subjects in the experimental group who performed the deep lumbar muscle stabilization exercise and 10 subjects in the control group who performed a regular exercise. Variables that represent the spatiotemporal walking ability (step length, stride length, step rate, and walking speed) were measured using GAITRrite before and after the experiment and were analyzed. Results: There was a significant difference in the pre- and post-exercise spatiotemporal walking ability between the two groups (p<.05). Furthermore, there was a significant difference in the step rate and walking speed between the two groups (p<.05). Conclusions: Deep lumbar muscle stabilization exercise is effective in improving the walking ability of stroke patients. Therefore, its application will help improve the spatiotemporal walking ability of stroke patients.
