The purpose of this work is to predict the systolic blood pressure (BP) during exercise from pulse transit time (PTT) for warning of possible danger. PTT was calculated as the time between R-peak of ECG and the peak of differential photoplethysmograph (PPG). For the PTT-BP model, we used regress equations from previous studies and 3 kinds of new models combining linear and nonlinear regress equation. The model parameters were estimated with the data measured under low to middle intensity exercise, and then was tested with the data measured under high intensity exercise. Predicted BP values after high intensity exercise were compared with those measured by cuff-type sphygmomanometer. The results showed that the error between measured and predicted values were acceptable for the monitoring BP. We tested PTT-BP models 1 month after the identification without further calibration. Models could predict the BP and the errors between measured and predicted BP were about 5mmHg. The suggested system is expected to be helpful in recognizing any danger during exercise.

The aim of the experiments was to investigate the effect of Semen Cuscutae aqua-acupuncture at the meridian point BL 20(脾兪) and BL 23(賢兪) on the blood pressure, plasma renin activity, plasma levels of aldosterone and atrial natriuretic peptide (ANP) in spontaneously hypertensive rats (SHR). The results of this study were as follows: 1. Systolic blood pressure was decreased significantly after Semen Cuscutae aqua-acupuncture at the meridian point BL 20, BL 23. 2. Plasma renin activity was increased significantly after Semen Cuscutae aqua-acupuncture at meridian point BL 23, BL 20. 3. Plasma levels of aldosterone was increased significantly after Semen Cuscutae aqua-acupuncture at the meridian point BL 20. 4. Plasma levels of atrial natriuretic peptide (ANP) was increased significantly after Semen Cuscutae aqua-acupuncture at the meridian point BL 23, but it was decreased significantly after Semen Cuscutae aqua-acupuncture at the meridian point BL 20. These results suggest that the changes of the depressor response after Semen Cuscutae aqua-acupuncture at the meridian point BL 20, BL 23 are related to the changes of the plasma renin activity, plasma levels of atrial natriuretic peptide (ANP) and aldosterone.

Purpose: The study compared the hypertension care efficacy of a case management intervention program for registered clients. Methods: The nonequivalent control group pretest-posttest design involved 53 registered hypertensive patients of a customized visiting health care service in S-city(n=28 experimental group, n=25 control group). Data collection and case management intervention were carried out from April to July, 2009. The experimental group had six home visits and two phone calls, and the control group had two home visits during the 8-week period. Outcome variables for test hypotheses were changes in physiologic index (blood pressure and total cholesterol) and degree of self-management performance and confidence. Results: Repeated measure ANOVA and t-test of means revealed significant differences before and after program for systolic and diastolic blood pressure and self-management performance and confidence, but no significant difference concerning total cholesterol. Conclusion: A case management program can have positive effects on blood pressure control and self management. However, research is needed to create a more effective case management for vulnerable patient populations.

Purpose: This study aimed to verify the effects of preoperative video education on delirium and anxiety in elderly patients with general anesthesia. Methods: This study used quasi-experimental research with a non-equivalent control group non-synchronized design. Participants were 70 elderly patients who had undergone of surgery under general anesthesia (35 in the experimental group and 35 in the control group). Preoperative video education was given to the experimental group. Subjective anxiety, blood pressure, pulse and delirium were measured. Data were analyzed using descriptive statistics, test of homogeneity in pretest, independent t-tests, and two-way repeated measures ANOVA with the SPSS/Win 22.0 program. Results: Delirium of the experimental group was significantly lower than that of the control group. Subjective anxiety measured using visual analogue scale was not significantly different between the two groups. However, there was a significant difference in the interaction between the group and time. There was no significant difference in physiological anxiety measured using systolic blood pressure, diastolic blood pressure and pulse between the two groups. Conclusion: The findings suggest that preoperative video education may contribute to reducing delirium and subjective anxiety for elderly patients after surgery.

The isometric torque of the elbow flexor and extensor muscles were measured for 6 seconds at a joint angle of 90$^{\circ}$ , in 10 normal subjects (control group) and 10 hemiplegic subjects(patient group), using the Cybex NORMTM System. The peak torque, the time to peak torque were measured for each exercise. In addition, heart rate and blood pressure were recorded simultaneously at rest and immediately following exercise completion at 1 and 3m mutes. Statistical analysis was performed using SPSS 8.0 for Windows software and mean and standard deviations were calculated. The results are as follows. 1) In the patient involved group. the isometric values for flexors and extensors were significantly lower than in the normal nondominant group(p<.05). 2) The extensor to flexor strength ratio in the isometric mode was 121.0% in the patient involved group compared with 78.7%in the normal nondominant group, a significant difference(p<.05). 3) The mean increment ratio was increased 19.0% for systolic blood pressure and 25.2% for disatolic blood pressure in the patient group. 4) The mean increment ratio was increased 36.0% heart rate in the patient group.

The aim of this study was to investigate the interrelationship among urinary excretion dietary habit of Na, Ca intake and hormonal factors in 22 hypertensive and 30 normotensive hospitalized patients. The results were summarized as follows : 1. Urinary excretion of Na in normotensive patients was not significantly different from that of hypertensive patients, while Ca excretion(as expressed on the basis of mg of creatinine) was significantly higher in hypertensive patients. 2. Habitual dietary intake of Na, Ca in hypertensive patients were not significantly different from those of normotensive patients. 3. There were no significant differences in mean plasma renin activity, aldosterone and parathyroid hormone(PTH) level between two groups. However, systolic pressure significantly correlated with PTH(r=0.2597) and aldosterone level(r=0.24648)(P<0.05). In this study blood pressure did not show any significant relationship between urinary Na excretion and habitual dietary Na intake of Na. It is speculated that individual difference of Na sensitivity might result in heterogenous blood pressure response to dietary Na intake. Higher Ca excretion in hypertensive subjects suggested a future study on the interrelationship between Ca metabolism and aldosterone system in hypertension.
