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.

당뇨병 환자에서 고혈압의 빈도는 일반인에 비해 2배 이상 높고, 대개 환자의 약 40$\~$60$\%$에서 고혈압을 동반한다. 고혈압이 당뇨병과 같이 있는 경우는 대혈관 및 미세혈관 질환의 위험인자로서 작용하여 심장사, 관상동맥 질환, 울혈성 심부전, 뇌혈관질환, 그리고 말초혈관 질환의 발생 위험을 높여 당뇨병 환자 사망원인의 대부분을 차지하며, 고혈압이 동반되어 있지 않을 경우에는 장기생존률이 높다. 또한 당뇨병에서 확장기 및 수축기 혈압은 당뇨병성 신증과 망막증의 발생 및 경과 악화에도 영향을 미친다. 당뇨병에서 고혈압이 예후에 중대한 영향을 미치는 만큼, 고혈압을 동반한 당뇨병 환자에서, 혈당의 조절뿐 아니라 죽상경화증의 예방 및 고혈압의 치료가 당뇨병에 의한 혈관 합병증의 발생과 진행을 지연시키고 사망률을 감소시키는데 결정적이라 할 수 있다.

In this paper, an ECG-NIBP patient monitor is designed. This is an essential equipment to measure and monitor patient's physical condition - electrocardiogram(ECG) wave, heart rate(HR), and noninvasive blood pressure(NIBP) - in ICU, CCU, and operating room. The ECG is an electrical waveform produced by relaxation and contraction of the cardiac muscle. Most physicians diagnose patient's cardiac states from ECG pattern. A blood pressure is one of the clinical indexes measured in a emergency room or operating room. In this paper, the blood pressure is measured in artery by using the nonivasive oscillometric method. The developed patient monitor was inspected and compared with other instruments in operating rooms. The results were 1bpm of maximum difference in the heart rate, 15mmHg in the systolic pressure, 16mmHg in the diastolic pressure, and 25mmHg in the mean blood pressure. But the total results were 0.15bpm of the mean difference in the heart rate, 5mmHg in the systolic pressure, 10mmHg in the diastolic pressure, and 9mmHg in the mean blood pressure. The designed ECG-NIBP patient monitor can measure the ECG wave, HR, and BP. And the multi-tasking module of pulse oximetry . respiration . temperature monitor will be added in the near future.

The purpose of this study was to identify the effect of the Smart Care ubiquitous healthcare service on hypertension management. Fifty one patients with inadequately controlled blood pressure (Systolic Blood Pressure ${\geq}$ 140 mmHg despite prescribed antihypertensive medication) from 4 local clinics participated in this study. Remote biometric monitoring and healthcare consultation via videophone was provided to the participants during 24 week - Smart Care service. The average number of blood pressure monitoring and the average day of remote consult using Smart Care Service system was 121 and 14.8 per participant. As a result of analyzing change in blood pressure during 24 weeks, there was a significant difference in blood pressure between baseline and 24 weeks. Systolic blood pressures of 86.3% participants were dropped within a normal range at 24 week. Smart Care u-health service could be effective in reducing blood pressure.

Obesity is the risk factor of atherosclerosis and not only increases triglyceride concentration in blood but also decreases relatively the ratio of TG to HDL-Cholesterol in blood. In case of obesity, systolic blood pressure is also increased in responding the increase of TG in blood. Index of obesity in red ginseng-taking group (ginseng group) was lower as compared with non-red ginseng-taking group (control group). The TG concentration, the ratio of triglyceride to HDL-cholesterol in blood and systolic blood pressure were decreased in the subjects of ginseng group compared with that in control group. It is inferred that long-term intake of ginseng products may help to prevent the risk of atherosclerosis and obesity.

Purpose : Adolescent obesity is known to be associated with complications such as hypertension, coronary artery disease and insulin resistance. We measured the common carotid artery by ultrasound as a predictor of atherosclerosis, and investigated the relationship between carotid artery parameters and serum cytokines in obese adolescents. Methods : Twenty-nine obese adolescents(16-17 years old, obesity index>130 percent) and twentyseven normal controls were included. Obesity index and body mass index were calculated from their height and weight. Skin fold thickness was measured at the triceps, and fat mass and fat distribution by bioelectrical impedence analysis. Blood pressure was measured at resting state and serum lipid, insulin, and homocysteine levels after a 12-hour fasting period. Intimal wall thickness, systolic and diastolic diameters of the common carotid artery were measured by ultrasound, and compliance and distensibility calculated by equation. Results : Systolic and diastolic diameters of the carotid artery significantly correlated with arm circumference, body mass index, fat distribution and fat mass. The higher systolic blood pressure was, the larger systolic and diastolic diameter. The higher diastolic blood pressure was, the larger carotid intimal thickness. Insulin levels had positive correlations with systolic, diastolic diameters and serum homocysteine level with intimal thickness. Conclusion : The carotid artery diameter significantly increased with the degree of obesity and blood pressure. The carotid intimal wall thickness significantly correlated with diastolic blood pressure. Measurement of carotid artery thickness, insulin and homocysteine levels might be useful to predict the development of coronary artery disease.

Gene polymorphisms that are associated with sodium homeostasis in the body, such as $\alpha-adducin$ (ADDI, Gly460Trp), angiotensinogen (AGT, Met235Thr), and angiotensin converting enzyme (ACE, Ins/Del) may increase the risk for the development of hypertension. The purpose of this study was to elucidate the relationship between the singular and combined effects of ADD1, AGT, ACE genotypes, and blood pressure in elderly population. Moreover, we examined the interaction of sodium intake and polymorphisms of aforementioned genes and their effects on blood pressure. Among one hundred and nine female subjects, aged 60 and over (mean 75.9 yr), the major alleles for ADD1, AGT, and ACE polymorphisms in the studied population were Gly (66.1%), Thr (64.2%), Ins (83.5%), respectively. Analysis on the combined effects of genetic variation showed that subjects who were both ADD1 Trp/Trp and ACE Del/Del homozygotes had significantly higher systolic blood pressure (p=0.01). Similarly, ACE Del/Del homozygotes who had AGT Met allele had significantly higher diastolic blood pressure (p<0.001). However, in single-gene analyses, no association was found between any specific genotype and blood pressure. In subjects with low sodium intake, ADD1 Trp/Trp homozygotes had significantly higher systolic blood pressure than subjects who had ADD1 Gly allele (138 mmHg vs. 127 mmHg, p=0.03). There was no difference in blood pressure between ADD1 Trp/Trp and ADD1 Gly/Gly or Gly/Trp, in subjects with high sodium intake. In summary, this study shows that interactions between the ADD1, AGT and ACE genes influence systolic and diastolic blood pressure in elderly subjects, and dietary sodium intake can modulate the effects of ADD1 Gly460Trp polymorphisms on systolic blood pres sure.

Recently, product research has been continuously conducted to enhance accessibility to blood pressure measurement for the purpose of healthcare for the chronic patient. In previous studies, electrocardiogram (ECG) and photoelectric pulse wave (PPG) are analyzed to calculate systolic and diastolic blood pressure. The problem is the development of analysis algorithms for accuracy and reproducibility. In this study, in the development stage of a micro blood pressure measuring device, the size of the device was reduced and the measurement method was simplified, while the algorithm was to extract systolic blood pressure (SBP) using only two PPGs and obtain diastolic blood pressure (DBP). The difference value of PPG, DF_P, is inversely related to SBP, and has a proportional relationship with DBP, which can be leaked by algorithm, and DBP can be tracked through SBP.
