This paper presents a method for predicting blood pressure using the photoplethysmography signals. First, after measuring the optical blood flow signal, artifacts are removed through a preprocessing process, and a signal for learning is obtained. In addition, weight and height, which affect blood pressure, are measured as additional information. Next, a system is built to estimate systolic and diastolic blood pressure by learning the photoplethysmography signals, height, and weight as input variables through an artificial intelligence algorithm. The constructed system predicts the systolic and diastolic blood pressures using the inputs. The proposed method can continuously predict blood pressure in real time by receiving photoplethysmography signals that reflect the state of the heart and blood vessels, and the height and weight of the subject in an unconstrained method. In order to confirm the usefulness of the artificial intelligence-based blood pressure prediction system presented in this study, the usefulness of the results is verified by comparing the measured blood pressure with the predicted blood pressure.

This study conducted the following experiment to examine effects of cardiovascular function on lumbar stabilization exercise(LSE) in floor or swiss ball. This experiment was conducted to compare heart rate, systolic blood pressure, diastolic blood pressure and peripheral vascular oxygen saturation effects by lumbar stabilization exercise in floor or swiss ball with 18 normal adult and it divided 9 subjects. experiment group (1) is applying LSE on floor group and (2) is applying LSE on swiss ball group. Heart rate was measured by portable heart rate manometer, blood pressure was measured by hemodynamometer, and peripheral vascular oxygen concentration was measured using a computerized NURYTEC measuring apparatus analysis. These result lead us to the conclusion that systolic blood pressure and peripheral vascular oxygen concentration were influenced by LSE. but there was not differential effect between each groups. These results suggest that LSE has the capability to improve heart rate, blood pressure, peripheral vascular oxygen concentration. Consequently, LSE would be lead to increment of cardiovascular function.

The purpose of this study was to investigate the changes of blood pressure and total cholesterol after eating Hizikia fusiforme for 8 weeks with 100g of rice per day. As a result, the systolic blood pressure of the group ingesting Hizikia fusiforme significantly decreased. Second, diastolic blood pressure decreased significantly in both groups, but there was no difference between groups. Third, the systolic - diastolic blood pressure difference showed a significant decrease in the group of ingestion of Hizikia fusiforme, while that of the group without intake of Hizikia fusiforme increased. Fourth, total cholesterol decreased significantly in the group consuming Hizikia fusiforme but increased in the group not consuming Hizikia fusiforme. The above results indicate that total intake of 100 g of dried Hizikia fusiforme per day was effective in decreasing total cholesterol and reducing systolic blood pressure.

The purpose of this study was to investigate the changes in the vital signs and anxiety reactions during scaling to patients who had received the dental hygiene treatment at department of Dental Hygiene in a university. A total of 189 patients were participated in the study. The level of anxiety was assessed through a dental anxiety questionnaire consisting of dental fear survey scale and dental anxiety survey scale. The vital signs were measured before and after scaling. The obtained results were as follows. The level of anxiety before scaling was 2.16 and after scaling was 1.96. This was significantly higher in women. The pulse and systolic blood pressure after scaling significantly decreased from 77.48 times to 74.36 times per minute and from 124.96 mmHg to 122.50 mmHg respectively. These changes are within the normal physiological variations. Individual changes in respiration, pulse, blood pressure, body temperature are affected by age, gender and previous dental experience, but previous scaling experience. The level of anxiety was significantly explained by respiration before scaling and pulse after scaling. As a result, scaling was associated with dental anxiety reactions and changes in vital signs.

The purpose of this study is to investigate the vasodilatation effect of kirenol isolated from Sigesbeckia pubescens on the rabbit basilar artery. In this study, to determine the vasodilatation effect of kirenol on the rabbit basilar artery, arterial rings with intact or damaged endothelium were used for the experiment. And used an organ bath and force transducer were contracted by endothelin. Kirenol, major active constituents of S. pubescens, showed a moderate vasodilatation effect on the basilar arteries of rabbits. Therefore, treatment with kirenol may selectively accelerate cerebral blood flow through dilatation of the basilar artery. This result suggests a potential role of kirenol isolated from S. pubescens as a source of vasodilatation agent.

Objective: The purpose of this study was to identify differences in measurement methods for blood pressure (Direct measurement, HP automatic indirect measurement, and SE 7000 Korean made indirect measurement), and to evaluate the clinical trial of the Korean made automatic indirect blood pressure measurement. Material & Methods: From June, 1999 to February, 2000, fifty five consecutive patients were randomized into hypertension group (n=20), normotension group (n=20), and hypotension group (n= 15). Measuring blood pressure by indirect methods (HP NIBP M 1008B and SE 7000 NIBP Korean made) was done simultaneously in the same arm with arterial line for direct blood pressure measurement (HP M1006A). The procedures were repeated ten times at intervals of 2 minutes. Statistical analysis was Performed using SPSS (version 8.0 for windows) software package. Values were expressed as means and standard deviation and means were compared using t-test. Statistical significance was considered present with a p value less than 0.05. Results: In the hypertension group and noromotension group, the disparity between HP direct measurement and indirect SE 7000 NIBP did not show any differences compared to the disparity between HP direct measurement and indirect HP NIBP. In the hypotension group, the disparity in the diastolic pressure between HP direct measurement and indirect SE 7000 NIBP was significantly different compared to the disparity between HP direct measurement and indirect HP NIBP (p<0.001), however, disparities in systolic pressure did not showed any differences. Conclusion: Direct blood pressure measurement (HP M1006A) can be replaced with indirect blood pressure measurements (HP NIBP M 1008B & SE 7000 NIBP) in normotension and hypertension patients. Korean made indirect measurement was found to be more accurate compared to HP indirect measurement in hypotension Patients, but more study is needed.

This research is to know about how $VO_2peak$ effects on Abdominal circumference, Blood lipids and blood presure with diabetes patients. After that, we have reached the final decision. in terms of the patients, there is significant indication that Abdominal circumference and HDL-cholesterol are related to $VO_2peak$. And Non-patients and $VO_2peak$ are related to each other though. $VO_2peak$ of the patients significantly effects on Abdominal circumference. Also, $VO_2peak$ of Nom-patients are same in aspect of Diastolic blood pressure As for Abdominal circumference, $VO_2peak$, High-density lipoprotein (HDL) cholesterol, Triglyceride, blood pressure, they are significantly associated to each other For These reasons, we have suggested that $VO_2peak$ seems to be possible to be handled by monitoring index for dangerous factors. Futhermore, exercise is really regarded as the best way of improving Cardiopulmonary capacity.

Background: We performed a phase IV clinical trial to examine the usefulness of a continuous infusion of nicardipine hydrochloride to control hypertension in patients with acute aortic dissection. material and Method: Systolic/diastolic blood pressure, and heart rate were monitored before and after the intravenous administration of nicardipine in 31 patients with aortic diseases. The period of nicardipine administration in each patient was from 3 to 14 days. Efficacy was evaluated by determining the average amount of blood pressure reduction on the 3rd day of drug administration. The dosage of another antihypertensive agent was slowly tapered down, and ultimately replaced by the test drug. Result: 28 patients were diagnosed as acute aortic dissection, 2 patients as rupture of the aortic arch aneurysm, and 1 patient as traumatic aortic rupture. Mean age was 53.9 $\pm$ 14.9(29~89) years, and 21 patients(67.7%) were male. 14 patients(32.3%) had complications associated with underlying aortic disease: aortic insufficiency in 7, hemopericardium in 6, acute renal failure in 1, paraplegia in 1, lower extremity ischemia in 1, and hemothorax in 1. The time needed to reach the target blood pressure was within 15 minutes in 16, from 15 to 30 minutes in 10, from 30 to 45 minutes in 3 and from 45 to 60 minutes in 2, and their baseline average systolic, diastolic, and mean arterial blood pressures(mmHg) were 147$\pm$23, 82.3$\pm$ 18.6, and 104 $\pm$ 18, respectively. Average systolic, diastolic, and mean arterial blood pressures(mmHg) on the third day of nicardipine infusion were 119$\pm$ 12, 69$\pm$9, and 86$\pm$8, and they all showed statistically significant decrease(p<0.05). The average systolic, diastolic, and mean arterial blood pressure(mmHg) after the discontinuation of the nicardipine infusion were 119 $\pm$ 15, 71 $\pm$ 14, and 86$\pm$ 13, respectively. No significant difference was observed between the average pressures measured on the third day and those measured after the discontinuation of the nicardipine infusion, and no definite side effects were observed during the study period. Conclusion: Nicardipine hydrochloride was both effective and safe at controlling blood pressure in patients with acute aortic dissection.
