Invasive hemodynamic monitoring has become a valuable assessment parameters in critical care nursing in patients undergoing open heart surgery patients. During cardiac surgery, the Swan Ganz catheter is placed in the pulmonary artery. Critical care nurses routinely obtain cardiac output, cardiac index, and pulmonary arterial pressure in these patients. Traditionally, patients are positioned flat and supine for cardiac output measurement. Numerous studies have dealt with the effects of changing position on the hemodynamic variables. However, there are a few studies dealing with patients who undergo cardiac surgery in Korea. Thus, the purpose of this study was to determine the effects of changing position on cardiac output, PAP, CVP, BP, HR and discomfort in patients after cardiac surgery. A sample of 21 adults who had CABG and/or valve replacement with Swan Ganz catheters in place was studied. The data were collected in the cardiac ICU of a university hospital in Seoul during the period from July 28, 1999 to August 30. 1999. In this study, the independent variable is patient position in the supine, 30 degree, and 45 degree angles. Dependent variables are C.O., C.I., CVP, PAP, MAP, HR and patients' perceived discomforts. Subject discomfort was measured subjectively by visual analogue scale. Other hemodynamic data where collected by the thermodilution method and by direct measurement. The data were analyzed by percentile, t-test, ANOVA, Linear regression analysis using SPSS-/WIN program. The results are as follows : 1) Changes in cardiac output were absent in different angle positions, 0, 30. 45 degrees(F=.070, P=.932). Changes in cardiac index were absent in different angle positions, 0. 30, 45 degrees(P>.05). 2) Changes in central venous pressure were absent in different angle positions, 0, 30, 45 degree(P>.05). 3) PAP had no change in different angle 0, 30, 45 degree positions; systolic PAP(P>.05), diastolic PAP(P>.05). 4) Changes in systolic blood pressure were absent in different angle positions, 0, 30, 45 degree(P>.05). 5) Changes in heart rates were absent in different angle positions, 0, 30, 45 degree(P>.05). 6) Patients' perceived discomfort was absent in different angle positions, 0, 30, 45 degree(p<.05). In conclusion, critical care nurses can measure C.O., C.I., PAP, BP, & CVP in cardiac surgery patients at 30 degree or 45 degree positions. This can improve the patients' comfort.

This study was conducted to compare the validity of obese index among body mass index(BMI), waist to hip ratio(WHR), and waist circumference(WC) and to determine which is the best in relation to cardiovascular risk factors of middle aged Korean(40-64yr).Data from the 1998 Korean Health and Nutrition Survey were used(N=3380). Anthropometric indices and cardiovascular risk factors were measured. Chi-square test, analysis of variance following duncan's multiple range test, partial correlation analysis, and Receiver Operator characteristic(ROC) curves were used in the analysis. There was a significant increasing trend in WHR, systolic blood pressure(SBP), high density lipoprotein cholesterol(HDL), and fasting blood sugar(FBS) with age categories of male and in BMI, WC, WHR, diastolic blood pressure(DBP), SBP, total cholesterol(TC), low density lipoprotein cholesterol(LDL), triglycerol(TG), and FBS with those of female. Specially female had the characteristics of upper body fat and systolic blood pressure risk(p<0.05). Proportions of subjects with lifestyle factors related to cardiovascular risk in overweight or upper body fat group were higher than that of normal group. Higher proportions of subjects were practiced exercise in upper body fat group of male than in other groups. Among 7 cardiovascular risk factors in partial correlation analysis, BMI had the highest correlation coefficient in 6 risk factors in male, whereas WC in 4 risk factors in female. Mean of each obese index according to cardiovascular risk groups except smoker was higher than that of normal(p<0.05). These trends were shown in upper body fat group and female. In ROC analysis of 12 risk factors and health conditions, the largest area under curve among obese indices for risk factors were BMI in male and WHR in female. The optimal cutoff values of each index(BMI: WHR: WC) for one or more cardiovascular risk factors were 23.13: 0.89: 85.35 in male and 23.57: 0.84: 78.35 in female. The results showed that cardiovascular risk factors were prevalent in middle aged Koreans within normal limits of obese indices like another Asians. For the identification of cardiovascular risk factors of middle aged Koreans, BMI for men and WHR for women are appropriate indices. But it is recommended that BMI, WHR, and WC, all three indices should be considered, when using these indices.

Exercises are achievement oriented, the process is frequently perceived as hard and difficult Participants drop out from exercise programs in the middle of the training period. Dance movement, which is the deliberate and systematic use of movement, is enjoyable during the movement and provides opportunities for persons to express them-selves. Regular long term dance movement may in-duce a training effect with a decreased drop out rate. Dance movement could be one way to attain wellness, however, there have been few studies to evaluate both physiological and psychological aspects of dance movement. This study focused on evaluating the effects of dance movement training on body weight, resting blood pressure and heart rate, limb circumference and strength, stress response and subjective feelings. This quasi-experimental study was designed as a nonequivalent control group pre test -post test study. Ten healthy fe-male subjects, aged between 19 and 31 years volunteered for an eight week dance movement program. Ten healthy female subjects, between 19 and 21 years of age paticipated as controls. None of the subjects had performed regular physical activity for six months prior to the study. Dance movement was created with reference to Heber's movement guide. The Dance movement program consisted of approximately 30 minutes of dance, three days per week, for eight weeks. During each 30 minute work out, there were approximately 5 minutes of warm-up dancing, 20 minutes of conditioning dance and 5 minutes of cool-down dancing. The intensity for the conditioning phase was at between 60% and 65% of age-adjusted maximum heart rates. Body weight, resting blood pressure and heart rate, circumference of mid upper arm, mid thigh and mid calf, muscle strength of upper and lower limb, physical and psychological response to stress were measured prior to, and following the experimental treatment. Body weight was measured by digital weight scale(Kyung In Corp., Korea). Resting systolic and diastolic blood pressure were measured by sphygmomanometer, Resting heart rate was measured for one minute in a relaxed sitting position using the radial artery. Circumference of mid upper arm, mid thigh and mid calf was determined by tape measure. Muscle strength of the upper extremities was measured by a grip dynamometer (Takei Corp. No.1857, Japan) and that of the extremities was measured by the length of time the leg could be held at 45° Physical and psychological responses to stress were measured using the Symptoms of Stress (SOS)Scale. Paticipants in the dance movement were interviewed by the facilitator following the eight weeks, and their thematic responses about the dance movement were recorded. Following the eight week dance movement train-ing, body weight decreased significantly, circumference of mid thigh and mid calf increased. The length of time leg - raising could be held tended to increase following the dance movement training. Resting systolic and resting heart rate showed a tendency to decrease. Total mean score of stress response tended to de-crease, and mean score of habitual patterns, do-pression, anxiety / fear, anger and cognitive disorganization decreased remarkably following the eight week dance movement. Thematic responses about the dance movement were positive following the training.

Objectives : The purpose of this study is to identify the effect of tonifying or sedative manipulation on LI4 and KI7 for sweet deficiency under cold environment. Methods : The participants were divided into 4 groups; intact group without acupuncture(Intact), acupuncture group inserting straightly with LI4 & KI7 method((LI4-straight KI7-straight), acupuncture group inserting twisting with LI4 tonificaton & KI7 tonificaton method(LI4-tonify KI7-tonify) and acupuncture group inserting twisting with LI4 sedation & KI7 sedation method(LI4-purge KI7-purge). We obtained the baseline data under cold condition with the temperature $14{\pm}1^{\circ}C$. After making the participant staying under cold condition for 10 minute, we measured sweating rate on skin surface and biological responses such as body temperature, oxygen saturation, pulse rate, systolic blood pressure, diastolic blood pressure, deoxy-Hb and oxy-Hb in subcutaneous. Results : The sweating rate on skin surface was not different in all treatment groups compared to the intact group. The body temperature was significantly increased in LI4-straight KI7-straight group compared to the intact group. The oxygen saturation significantly increased in LI4-purge KI7-purge group compared to the intact group. The systolic blood pressure was significantly increased in LI4-purge KI7-purge group compared to the intact group. The deoxy-Hb was significantly decreased in LI4-purge KI7-purge group compared to the intact group. Conclusions : The above results, the effect of LI4, KI7 acupuncture due to the tonifying or sedative manipulation on sweating control could be observed. However, other biological responses with the acupuncture of tonifying or sedative manipulation were giving different expressions. We suggest that continued research of tonifying or sedative manipulation is of importance order to find these expressions.

This study was performed to find a relationship between each pattern identification and vascular status using the second derivative of photoplethysmogram waveform(SDPTG) indices. We analyzed 200 subjects who participated in stroke preventive examination. We classified the subjects into four groups of pattern identifications; Fire-Heat pattern(火熱證; FH), Yin Deficiency pattern(陰虛證; YD), Qi Deficiency pattern(氣虛證; QD) and Dampness-Phlegm pattern(濕痰證; DP) that based on Korean Standard Pattern Identifications for Stroke-Ⅲ. We studied a relationship between each pattern identification and the SDPTG. The total number of the subject group was 200, whereas the groups were divided into four groups; Fire-Heat pattern group(n=49), Yin Deficiency pattern(n=57), Qi Deficiency pattern(n=45), and Dampness-Phlegm pattern(n=49). b/a ratio was related with age and systolic blood pressure, c/a ratio was associated with age, systolic blood pressure, fasting blood sugar and Total cholesterol, d/a ratio was affected with age, diastolic blood pressure, and hypertension, e/a ratio was related with age and sex and SDPTG AI was associated with age. c/a ratio and d/a ratio were significantly higher in the Fire-Heat group than in the Qi Deficiency group. SDPTG AI was significantly higher in the Qi Deficiency group than in the Fire-Heat group. The Qi Deficiency group was significantly older than the Fire-Heat group and the number of hypertension patients was significantly more in the Fire-Heat group than in the Qi Deficiency group. Through this study, we found out some significant relationships between each pattern identification group and the SDPTG indices.

The purpose of this study was to provide obese middle school girls with walking and behavior modification program(WBMP) by investigating effects of the exercise on their body composition(BC), physical fitness(PF) and metabolic syndrome(MS). Analysis result of the difference between before and after the exercise(paired and independent t-test) was acquired by measuring BC, PF and MS for 12 weeks(60min/day, three a week). 24 Volunteers were 14 years over ${\geq}223.64kg/m^2$ and 15 years over ${\geq}24.00kg/m^2$. In the body composition, waist circumference(WC), body fat mass(BFM), %fat, arm muscle circumference(AMC), total body water(TBW), physical score(PS) were significant difference between the exercise group(EG) and the control group(CG), also including all factors in PF. The components of metabolic syndrome were significant difference between EG and CG, but HDL-C, systolic & diastolic blood pressure were no difference. The metabolic syndrome factors by separate of waist girth were no difference between EG and CG, but BMI, diastolic blood pressure were significant difference. The prevalence of metabolic syndrome was 4 of 24(16.7%) before intervention, but it dropped from 2 to 1 after intervention in WBMP. The components of metabolic syndrome was distributed a big WC>low HDL-C>high TG>hypertension. The changes of AMC, We, PS, BW, 50m run and BFM effect the factors on BMI(35%), WHR(waist-hip ratio, 69%), HDL-C(42%), fasting blood glucose(65%), HOMA-IR index(34%) and systolic blood pressure(39%) respectively. There were significantly increased in breakfast frequency, walking steps, and meal eating period, but decreased in snacks and eating out in exercise group.

The subjects for the study were twenty four obese women(50's) composed of the exercise group(n=12) and to a "no exercise" control group(n=12). The variables of health-related fitness, blood pressure, and blood vessel elasticity where measured in all the subjects before the start of the training program and after at the end of the 8 weeks circuit training. The test data were analyzed by t-test, paired t-test, and alpha level of p<.05 was set for all tests of significance. Health-related fitness was exercise group, the BMI had significantly decreased, and the 20m shuttle run, sit-ups and sit-and-reach had significantly increased. Blood pressure was exercise group, the systolic blood pressure, and diastolic blood pressure had significantly decreased. Also, after the circuit training program, the exercise group had significantly higher diastolic blood pressure than did the control group. blood vessel elasticity was exercise group, the blood vessel elasticity had significantly decreased. And exercise group had significantly higher diastolic blood vessel elasticity than did the control group. In conclusion, BMI, systolic blood pressure, and diastolic blood pressure had significantly decreased, but 20 m shuttle run, sit-ups and sit-and-reach had significantly increased in the combined exercise group after the 8 weeks circuit training. Therefore, regular and continuous circuit training were effective in improving the body composition, blood pressure, blood vessel elasticity and health-related fitness.

Various factors influencing the lymph flow from thoracic duct were investigated in an attempt to evaluate their contributing degree and the mechanisms. Sixteen mongrel dogs weighing between 10 and 16 kg were anesthetized and polyethylene catheters were inserted into the thoracic duct and femoral veins. Arterial blood pressure, heart rate, central venous pressure, lymph pressure and lymph flow were measured under various conditions. Electrical stimulation of left sciatic nerve, stepwise increase of central venous pressure, manual application of rhythmical depressions onto abdomen, injection of hypertonic saline solution and histamine infusion were employed. Measurement of cental venous pressure was performed through the recording catheter inserted into abdominal inferior vena cava. Changes in central venous pressure were made by an air-ballooning catheter located higher than the tip of the recording catheter in the inferior vena cava. Lymph flow from thoracic duct was measured directly with a graduated centrifuge tube allowing the lymph to flow freely outward through the inserted cannula. The average side pressure of thoracic lymph was $1.1\;cmH_2O$ and lymph flow was 0.40 ml/min or 1.9 ml/kg-hr. Hemodynamic parameters including lymph flow were measure immediately before and after (or during) applying a condition. Stimulation of left sciatic nerve with a square wave (5/sec, 2 msec, 10V) caused the lymph flow to increase 1.4 times. The pattern of lymph flow from thoracic duct was not continuous throughout the respiratory cycle, but was continuous only during Inspiration. Slow and deep respiration appeared to increase the lymph flow than a rapid and shallow respiration. Relationship between central venous pressure and the lymph flow revealed a relatively direct proportionality; Regression equation was Lymph Flow (ml/kg-hr)=0.09 CVP$(cmH_2O)$+0.55, r=0.67. Manual depressions onto the abdomen in accordance with the respiratory cycle caused the lymph flow to increase most remarkably, e.g,. 5.5 times. The application of manual depressions showed a fluctuation of central venous pressure superimposed on the respiratory fluctuation. Hypertonic saline solution (2% NaCl) administered Intravenously by the amount of 10 m1/kg increased the lymph flow 4.6 times. The injection also increased arterial blood pressure, especially systolic Pressure, and the central venous pressure. Slow intravenous infusion of histamine with a rate of 14-32 ${\mu}g/min$ resulted in a remarkable increase in the lymph flow (4.7 times), in spite of much decrease in the blood pressure and a slight decrease in the central venous pressure.

Purpose: With increasing prevalence of hypertension (HTN) in children and adolescent, pediatricians have become more interested in blood pressure (BP) measurements. The ambulatory blood pressure monitoring (ABPM) is known to be useful to differentiate true HTN and white coat HTN. The object of this study is to assess the clinical usefulness of ABPM in Korean children and adolescents. Methods: A retrospective review of 51 patients in Kyungpook National University Hospital from January 2002 to February 2010 was done. All patients were 6-18 years old and underwent ABPM. We calculated the mean value of ABP, BP load, nocturnal dip and compared the results with the patients' diagnosis and characteristics. Results: The mean age of the 51 patients was $17.8{\pm}1.8$ years and 19 children were obese. 37 patients (72.5%) were truly hypertensive and 1 patient was diagnosed as masked HTN and 7 children (14%) as white coat HTN. The rest of the patients were normotensive. Among patients with white coat HTN, 5 were in a prehypertensive state. Mean systolic and diastolic BP load of patients with true HTN were significantly higher than non-hypertensive children (P<0.001). Although the nocturnal dip of all patients were below 10%, there was no statistical significance. The obese patients showed higher systolic and diastolic BP. Their systolic and diastolic BP load were significantly higher than non-obese patients (P<0.001). Conclusion: ABPM in children and adolescents seems to be a valuable tool in the assessment of white coat HTN and in the confirmation of true HTN. A considerable number of white coat HTN patients are revealed to be in a prehypertensive state and need close follow-up.
