This study examined effects of the communication accompanied with music therapy on the anxiety of patients during a MRI examination. In the experiment group consisting of thirty patients and the control group consisting of thirty patients, the experiment was performed from February 1st 2014 to March 31st 2014 in hospital C located in Daegu Korea. The research design was a non-equivalent control group quasi-experimental study. The results showed that the anxiety score (VAS score) on communication with music therapy of the experimental group was significantly lower (p=.001), than that of the control group. Among the vital signs, the blood pressure was similar in both groups. On the other hand, the pulse rate of the experiment group was significantly lower (p=.001). Four categories of the physical discomfort (perspiration, facial change, change in physical posture, and change in vocal sound) did not show any statistically significant difference between the control and experiment group. Among the mental discomforts, dizziness did not have a significant difference between the experiment group and the control group, but the experimental group had significantly low fear (p=.001) and anxiety (p=.001). From the above results, communication accompanying music therapy proves is an effective alternative examination method that reduces the anxiety of patients.

This study's purpose is to determine the effects of aroma inhalation on preoperative pain and anxiety of the elderly preparing to undergo a spine surgery. A Quasi-experimental design, with non-equivalent control group non-synchronized design was used in this study. Blended essential oils with frankincense, marjoram and mandarin were inhaled twice in the experimental group (n=30). The control group (n=30) was treated with the standard preoperative care. Pain, state anxiety, and vital sign were measured twice (before and after). The results of this study showed that pain (t=-1.223, p=.226), systolic blood pressure (t=-0.211, p=.833), diastolic blood pressure (t=0.638, p=.526), and respiration rate (t=0.734, p=.466) were not statistically significant in the experimental and the control group. There were significant differences in state anxiety (t=-3.202, p=.002) and pulse rate (t=-0.213, p=.037) in the experimental group compared to the control group. According to the results, aroma inhalation is an effective nursing intervention for relieving anxiety in surgical patients.

Hemorrhagic shock is a common cause of death in the emergency department. The purpose of this study was to investigate the relationship between blood loss as a percent of the total estimated blood volume (% blood loss) and changes in several physiological parameters. The other goal was to achieve an accurate prediction of percent blood loss for hemorrhagic shock in rats using a linear regression model. We allocated 60 Sprague-Dawley rats into four groups: 0ml, 2ml, 2.5ml, 3 mL/100 g during 15 min. We analyzed the heart rate, systolic and diastolic blood pressure, respiration rate, and body temperature in relation to the percent blood loss. We generated a linear regression model predicting the percent blood loss using a randomly chosen 360 data set and the R-square value of the model was 0.80. Root mean square error of the tested 360 data set using the linear regression was 5.7%. Even though the linear regression model is not directly applicable to clinical situation, our method of predicting % blood loss could be helpful in determining the necessary fluid volume for resuscitation in the future.

The purpose of this study is to find out the factors that affect the patient's exposure dose during the abdominal CT scan using the bolus tracking technique, and reducing the radiation exposure to the patient during the abdominal CT scan using the bolus tracking technique by adjusting the delay time according to the corresponding factor. The experiment was divided into two parts, and the first experiment was conducted with 300 patients There were 188 males and 112 females, and their average age was 58±12.18(19~85). In the second experiment, 150 subjects (100 males and 50 females) who were undergoing their follow-up examination among the first experiment subjects, and the difference in dose before and after was compared by applying the delay time according to the influencing factor. As a result of the first experiment, there was a relationship between the arrival time of the contrast media and the heart rate, and it was found that the arrival time decreased as the heart rate increased for both men and women. As a result of the second experiment, the average dose of CTDIvol and DLP before/after applying the delay time according to the heart rate decreased 4.98 mGy and 5.33 mGy·cm in the male group, and 3.54 mGy and 3.88 mGy·cm in the female group. By applying proper delay time according to the patient's heart rate during abdominal CT scan with the bolus tracking technique, the radiation exposure dose of the patient can be reduced.

This study is a quasi experimental study to investigate the effects of stroke prevention education program of Oriental Nursing on self-health perception, health behavior change, self-care and physiological index of adults over 55 years old and elderly people. The data were collected from August 12 to November 29, 2017. The 53 study subjects comprised 26 experimental subjects who agreed to participate in the education program and 27 control subjects. In the results, there was no statistically significant difference between the experimental group and the control group in general characteristics and research variables before the program; further, the two groups were homogenous. In the hypothesis test, the change in self-health perceptions of the experimental and control groups was t = -5.28 (p <.001), health behavior change was t = -4.24 (p <.001), self-care was t = -5.28 (p <.05), systolic blood pressure was t = 2.48 (p <.05), diastolic blood pressure was t = 2.78 (p <.05), and cholesterol was t = -3.94 (p <.001). There were statistically significant differences between the two groups and all four hypotheses were supported, which demonstrated the effectiveness of the program. These study results suggest that it is an effective program to change the self-perception of health and health behavior, improve self-care ability, and control the physiological index. It is expected that these findings will be useful in developing a future effective oriental nursing intervention. The education program should be continuously carried out, and the area needs to be expanded.

This study identified vitamin E associated with metabolic syndrome and metabolic syndrome components among Korean adults aged over 19 years. Secondary data from the 2016-2018 Korean National Health and Nutrition Examination Survey were used for this study. Data from 6,425 were analyzed by logistic regression analysis using a complex sample procedure. As a result of logistic regression analysis, the odds ratio was increased in the group with high vitamin E levels compared to the group with normal vitamin E levels. There are metabolic syndrome (Adjusted Odds Ratio [AOR]: 1.889, 95% Confidence Interval [CI]: 1.550-2.303, p<.001), abdominal obesity (AOR: 1.444, CI: 1.205-1.730, p<.001), hyperglyceridemia(AOR: 3.182, CI: 2.641-3.835, p<.001), systolic blood pressure (AOR: 1.711, CI: 1.446-2.026, p<.001), diastolic blood pressure (AOR: 1.806, CI: 1.521-2.144, p<.001), low high density lipoprotein cholesterol (AOR: 1.558, CI: 1.060-2.290, p=.024). Therefore vitamin E was associated with metaboic syndrome and metabolic syndrome components. So when providing nursing intervention for people with metabolic syndrome, education on vitamin E should be actively included.

The purpose of this study was to investigate the effects of 12-week training on changes in physical fitness and cardiovascular factors for firefighters. For this purpose, 40 men in their 20s and 30s who agreed to participate voluntarily were recruited. They were divided into four groups: the firefighters' physical fitness test training group (hereinafter referred to as PT group), firefighters' physical fitness test and aerobic training group (hereinafter referred to as PT+AR group), firefighters' physical fitness test and both aerobic and anaerobic training group (hereinafter referred to as PT+CO group). Physical fitness factors (grip strength, back muscle strength, seated forward bend, standing long jump, sit-ups, 20-meter shuttle run), cardiovascular factors (total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, glucose, waist circumference, systolic blood pressure, diastolic blood pressure) and the relationship between Framingham Heart Risk Score and physical/cardiovascular factors were compared and analyzed, and the following conclusions were obtained. Aerobic training, anaerobic training, and combined training, including 12 weeks of firefighter physical examinations, all had positive effects on fitness and cardiovascular factors, which would be an appropriate way for firefighter examinees to improve physical strength and reduce the risk of cardiovascular disease.

This study was aimed to examine the effects of intermittent walking on health related fitness and metabolic syndrome risk factors in elderly women. Forty five elderly women were randomly assigned to three groups: three 10-min walks per day, one 30-min walk per day or no exercise, respectively. Both walking groups exercised three days a week at moderate intensity for 12 weeks. Two-way repeated measures ANOVA was used to test the hypothesis with a significant level of α = .05. The results indicated that body composition(body weight, body mass index, percent body fat), muscle endurance, flexibility and cardiorespiratory fitness significantly increased after 12 weeks for both walking groups. However, it was found that muscle strength significantly increased only in a continuous walking group. Metabolic syndrome risk factors comprised of waist circumference, systolic blood pressure, triglyceride, high-density lipoprotein, and fasting glucose were significantly improved in both walking groups. In addition, there was a difference in these metabolic syndrome risk factors between pre and post exercise. The results of this study support the hypothesis that intermittent walking has a significant impact on health related physical fitness and metabolic syndrome rick factors in elderly women as continuous walking does.

Although alcohol drinking may cause fatty liver to induce hepatocytic injury, other factors lead to it. We designed this study to investigate the differences in serum iron, cardiac, and biochemical indices in men with fatty liver and the difference between alcohol drinkers (Alcohol group) and non-drinkers (Non-alcohol group). The alcohol group had higher body indices than the non-alcohol group. Systolic and diastolic blood pressure (SBP and DBP), and right and left intraocular pressure in the alcohol group were higher than those in the non-alcohol group. Hemoglobin, hematocrit, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and monocyte counts were higher in the alcohol group than in the non-alcohol group. Alanine aminotransferase, ${\gamma}$-glutamyltranspeptidase, total cholesterol, triglyceride, low-density lipoprotein cholesterol, glucose, creatinine, uric acid, iron, total iron binding capacity, and ferritin levels in the alcohol group were greater than those in the non-alcohol group. The present data reveals that alcohol-induced fatty liver has more elevated level of iron indices than in non-alcohol fatty liver as well as biochemical and cardiac indices, indicating that alcohol- induced fatty liver may cause possibility of adult diseases including cardiovascular disease and metabolic syndrome.

Background: Surgical closure of the PDA in premature infants with complications or contraindications to indomethacin use, or recurrence of symptomatic PDA is a safe and effective procedure with low operative risk and minimal complications. Material and Method: From April 1996 to August 1998, 11 premature infants with body weight under 1.5 kg at operation underwent operation for a symptomatic PDA (male:5, female: 6). Associated dise ases were congenital heart disease(7), hyaline membrane disease(6), intraventricular hemor rhage(4), pneumonia(4), pneumothorax(3), hyperbilirubinemia(2), necrotizing enterocolitis(2), renal failure(1), epilepsy(1), and hydrocephalus(1). Surgical techniques are hemoclipping(8) and ligation(3). The size of PDA was 3~6 mm (5.0$\pm$1.2). Result: Systolic and diastolic blood pressure rised and heart rates decreased after PDA closure. ABGA improved postoperatively. There were no surgical complications. Six infants with improved ABGA data were weaned from mechanical ventilatory support. The follow-up durations after discharge were 3 month to 12 month. Five deaths were not related to operation. The causes of death were hyaline membrane disease(2), bronchopulmonary dysplasia with pneumonia(1), sepsis(1), and con gestive heart failure with respiratory distress syndrome(1). Conclusion: Early operative closure is the treatment of choice in most premature infants with a hemodynamically significant shunt(PDA), recurrence of symptomatic PDA, complications of Indomethacin, or contraindi cations to Indomethacin.
