  • The purpose of this study was to test the effect of the structured preoperative teaching on post-operative recovery and to observe the effects of an structured preoperative teaching on the adult surgical patient's ventilatory function ability, the length of hospital stay, the number of analgesics within a 72 hour postoperative period, the length of early ambulation. The research question investigated in this study was: What would be the effects of a structured preoperative teaching upon the adult surgical patients postoperative recovery? This study was based on a sample of 40 patients who were scheduled for abdominal surgery. They were asssigned alternately to experimental and control group. Among 40 subjects, 20 were placed in the experimental group and 20 in the control group. Preoperative ventilation function testing of control and experimental subjects was done the evening before surgery and before the patient received the structured preoperative teaching. A structured preoperative teaching was given to the subjects in the exporimental group only by writer. Postoperative testing was done the 5th postoperative day. The data were collected over a period of two months, from Aug. 8 to Oct. 31, 1983. For the analysis of the data and test for the hypotheses, the t-test with mean difference was used. The results of this study regarding the four-hypotheses were as follows: 1. Experimental group which received structured preoperative eaching will have more increase to-cough and deep breathe as measured byhis forced vital capacity(FVC), forced expiratory volume 1 (FEV1), maximal voluntary volume 15 (MVV 15) than control group without structured preoperative teaching. The ventilation function ability was more increase in experimental group than in control group, the mean difference was statistically significant at 0.01 level. Hypotheses 1 was supported. 2. Experimental group with structured preoperative teaching will have more reduced the length of hospital stay than control group without structured preoperative teaching. The length of hospital stay of the experimental group and control group were 11.90 days and 16.05 days respectively. However, the difference was. not statistically significant at .05 level. Therefore the hypothese 2 was not supported. 3. Experimental group with structured preoperative teaching will have more reduce the number of analgesics within a 72 hour postoperative period than control group. The number of analgesics within a 72 hour' postoperative period of experimental group and control group were 1.65 times and 2.4 times. The difference was not statically significant at .05 level. Therefore, the hypotheses 3 was not supported. 4. Experimental group with structured preoperative. teaching will have more reduce the length of early ambulation than control group without structured preoperative teaching. The length of early ambulation of experimental group and control group were 2.2 days and 3.5 days respectively The difference was statistically signficant at 0.05 level. Thus the hypothess 4 was supported.

  • The purpose of this study was to investigate the effects of strengthening exercise program on the improvement of balance in the elderly Subjects were forty members living in Daegu (20 males, 20 females), between 65 and 81 years of age. The subjects were divided into two groups; an experimental group and a control group, and each group included 10 males and 10 females. The subjects for the experimental group were participated in the strengthening exercise program for 8 weeks, between April 2001 and June 2001 The results of this study were as follows: 1. General characteristics statistically significantly affecting for CTSIB were mental status; weight, height, vision, systolic blood pressure, diastolic blood pressure, pulse rate, mental status, obesity and thigh BMD were BBT; age, weight, height, vision, blood pressure systolic, blood pressure diastolic, blood pulse rate, mental status, obesity, spine BMD and thigh BMD were for OLST. 2. After the exercise program, there was no significant difference in the balance ability between the experimental group and the control group in CTSIB. However, there was a significant difference in OLSTR on the hard (p<0.05) and soft (p<0.05) surface with open eyes condition between the experimental group and the control group. In the case of OLSTL, there was a significant difference on the hard surface with open eyes condition (p<0.05), and on the soft surface with open eyes condition (p<0.05) and closed eyes condition (p<0.05) between the experimental group and the control group. There was no significant difference in the balance ability between the experimental group and the control group in BBT.

  • Thirty-six sinus grafts were performed in 34 patients with an alveolar crest bone height in the posterior maxilla of 3 to 5 mm before grafting. The sinuses were grafted using Bio-Oss alone or mixed with fibrin glue. Group 1 was the control group and included 25 patients who received a xenograft mixed in saline. Group 2 comprised 9 patients who received a xenograft and fibrin glue. The study was further subdivided at the time of 9 months. This histologic study evaluated by hematoxylin-eosin (H&E) and histomorphometric analysis whether fibrin glue in combination with Bio-Oss enhances bone regeneration in sinus floor elevation in humans. The new bone formation was better in Group 2 than in Group 1, but the difference was not significant. The absorption of the graft material was faster in Group 2 than in Group 1, in the short term, but better in Group 1 over the long term, although the difference was not significant. Lamellar bone was formed earlier in Group 1 compared to Group 2, but the difference was not significant. Overall, the surgery site stabilized earlier with new bone formation in Group 2 than in Group 1, but the difference was not significant. Combining a fibrin sealant and Bio-Oss could lead to improved scaffolds for bone tissue engineering based on the synergistic effects of the biomaterials. Therefore, Bio-Oss or Bio-Oss plus Tisseel may be used depending on the situation.

  • Purpose : This study purposed on the understanding of psychology in the elderly women using depression scale and electroephalography. The subjects were thirty elderly women in geriatric care hospital. All participants were elderly women over 65 years old. The subjects signed up with informed consent and they were divided into a normal elderly group, an exercise elderly group and a hospital elderly group. They were randomly assigned with 10 persons. Methods : The study instruments were Geriatric Depression Scale(GDS) and Poly-G-I. Brain wave activity was measured by 'power spectrum analysis' of TeleScan program. Statistic analysis consisted of average, standard deviation, One-way ANOVA and post-hoc Tukey using SPSS 21.0 version. The significance was set at .05. Results : Depression scale results showed that the exercise elderly group were $10.60{\pm}5.36$ points which was the lowest among the three groups. The Normal elderly group was $16.20{\pm}5.59$, and the hospitalized elderly group was $16.70{\pm}6.76$ points. There was no significant difference between the normal elderly group, exercise elderly group and hospitalized elderly group. The hospitalized group showed statistical difference in relative theta power in the area of Fp1, F3, F4, T3, P3 as compared to the normal elderly group and the exercise elderly groups. There was no significant difference between relative beta power and relative gamma power in three groups. Conclusion : Geriatric depressed scale showed no significant difference in each group. This is indicated in the mental problems associated with depression. This indicates a higher level of depression in the hospitalized elderly women, more than in the normal elderly women and exercise elderly women groups.

  • 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.

  • Background: Maintenance of adequate vascular access for hemodialysis is important in patients with end-stage renal disease. Once arteriovenous fistula (AVF) occlusion occurs, the patient should be treated with rescue therapy. This study was performed to evaluate the results of a rescue therapy for AVF occlusion. Methods: From January 2008 to December 2012, 47 patients who underwent surgical rescue therapy for AVF occlusion after graft AVF formation, were enrolled in this study. The patients were divided into two groups, namely the graft repair group (group A, n=19) and the thrombectomy group (group B, n=28). Postoperative results of both groups were analyzed retrospectively. Results: There were no statistically significant differences in the clinical characteristics between the two groups. In terms of the duration of AVF patency after the first rescue therapy, group A showed a longer AVF patency duration than group B ($24.5{\pm}21.9$ months versus $17.7{\pm}13.6$ months), but there was no statistically significant difference (p=0.310). In terms of the annual frequency of AVF occlusion after the rescue therapy of group A was lower than that of group B (0.59 versus 0.71), but there was no statistically significant difference (p=0.540). The AVF patency rates at 1, 2, 3, and 5 years after the first rescue therapy in group A were 52.6%, 31.5%, 21.0%, and 15.7%, respectively, and those in group B, they were 32.1%, 25.0%, 17.8%, and 7.14%, respectively. There was no statistically significant difference (p=0.402). Conclusion: Graft repair revealed comparable results. Although there was no statistically significant difference, the patent duration and annual frequency of AVF occlusion of group A were better than those of group B. Therefore, graft repair is considered as a safe and useful procedure for maintaining graft AVF.

  • Background: The purpose of this study was to provide the basis for the treatment intervention by identifying the treatment effect when rehabilitation intervention is applied to patients with dysphagia due to stroke and by comparing the results of the treatment mediation according to the differences of the treatment methods and frequency. Design: Randomized Controlled Trial. Methods: 30 people diagnosed with dysphagia due to stroke were divided in accordance with the differences in treatment mediation techniques and treatment frequency- traditional swallowing rehabilitation coupled with neuromuscular electrical stimulation group and only neuromuscular electrical stimulation group/ 5 times per week group and 2 times per week group, and ten weeks of treatment intervention was performed. Paired t test was employed to show the efficacy of treatment intervention, Independent sample t test was used to compare the results according to difference and number of treatment intervention techniques. Results: There was a significant positive effect of treatment on traditional swallowing rehabilitation coupled with neuromuscular electrical stimulation group, only neuromuscular electrical stimulation group, 5 times per week group and 2 times per week group (p<0.05). There was no statistically significant difference in treatment effect between traditional swallowing rehabilitation coupled with neuromuscular electrical stimulation group and only neuromuscular electrical stimulation group (p<0.05). There was no statistically significant difference in treatment effect between 5 times per week group and 2 times per week group (p<0.05). Conclusion: There was no significant difference according to the technique or number of treatments of swallowing rehabilitation treatment interventions, but it was confirmed that rehabilitation intervention for dysphagia showed positive treatment effect.

  • This study was to evaluate the body composition and bone mineral density according to aging in adult and investigated the relationship between various parameters such as body mass index(BMI), bone mineral density(BMD), bone mineral content(BMC), lean body mass(LBM), fat mass(FM) and the value obtained from dual energy X-ray absorptiometry(DEXA). The subjects were composed of healthy adult male and female who were $20^{\sim}73$ years old and they were divided three group according to age (A group : 20-39 yrs., B group : 40-59 yrs., C group : more than 60 yrs.). The conclusion derived from statistical analysis was as follows : 1. Bone mineral content and density were significantly affected by lean body mass(relatively, R=0.85 - 0.63). 2. There was significant difference among age groups in total bone mineral density. 3. There was significant difference among age groups in bone mineral content of male and female. 4. Lean body mass is diminished according to age, but there was not significant difference among age groups. 5. Fat mass of A group in male had the highest mass and followed by C group and B group. In female groups, fat mass of A group had the highest mass and followed by B group and C group. Abdominal fat mass is increased according to age. This result suggest that aging was closely relation with loss of muscle mass, bone mineral density and bone mineral content.

  • The purpose of this study was to determine whether vitamin {TEX}$B_{6}${/TEX} deficiency and age affect the blood cho-lesterol profile in exercising rats. Fifty four rats were fed either a viramin {TEX}$B_{6}${/TEX} deficient dief(-{TEX}$B_{6}${/TEX}) of a control diet(+{TEX}$B_{6}${/TEX}) for 6 weeks, then subdivided into 3 groups:non-exercise group(NE), exercise and sacrifice group(ES), exercise and recuperation group(ER). ES group was exercised in treadmill({TEX}$10^{o}${/TEX}, 0.5~0.8km/h) for 2 hours and sacrifice. ER group was recuperated three days with respective diet after exercise. At week 3 and 6, and level of plasma total cholesterol(TC), high density lipoprotein cholesterol(HDL_C) and low density lipoprotein cholesterol(LDL_C) were compared. In NE group, there was no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats. The plasma levels of TC and LDL_C of 6 weeks were higher than those of 3 weeks and on difference in HDL_V between 3 weeks rats and 6 weeks rats. In ES group, there was also no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats and there was no difference in TC, LDL-cholesterol between 3 weeks rats and 6 weeks rats. The level of HDL_C pf 6 weeks was lower than that of 3 weeks rats. In ER group, there was no difference in the levels of TC and LDL_C not only between +{TEX}$B_{6}${/TEX} rats and-{TEX}$B_{6}${/TEX} rats but also between 3 weeks rats and 6 weeks rats. The level of HDL_C was lower in -{TEX}$B_{6}${/TEX} rats than in +{TEX}$B_{6}${/TEX} rats and higher in 6 weeks rats than in 3 weeks rats. These results suggest that vitamin {TEX}$B_{6}${/TEX} deficiency may affect the HDL_C during exercise and after recuperation. The desirable effect of exercise on plasma Cholesterol profile is strengthened in adult age than young age.
