The body mass index, blood pressures and blood profiles of adults, who worked at three colleges in the Daejeon area, were evaluated for use in developing well-balanced menus at their workplace cafeterias and/or in creating nutrition education programs tailored to their health statuses. The data analyzed were from physical examinations performed in 2002 and in 2004 by the National Health Insurance Corporation. Overall, levels of systolic and diastolic blood pressure and serum cholesterol were lower in the 2004 samples than in those of 2002, but most samples in 2004 showed higher levels of SGOT. In 2002, statistical differences occured in the levels of blood pressure and serum cholesterol among age groups, but not in 2004. And in 2004, the older the age group, the higher the BMI. Among subjects in their twenties, three variables (systolic and diastolic blood pressure, and serum cholesterol) showed statistical differences; this increased to four variables (systolic and diastolic blood pressure, blood glucose and serum cholesterol) among subjects in their thirties and to six variables (Hb, SGOT, systolic and diastolic blood pressure, blood glucose and serum cholesterol) among those in their forties, followed by a decline to four variables (systolic and diastolic blood pressure, Hb and serum cholesterol) among subjects in their fifties. In general, the results of physical examinations showed improvements in blood pressure and blood profiles in 2004 in comparison with results in 2002. The level of SGOT was the exception. Despite these improvements, of those employees who had physical examinations in 2004, $5.2\%$ had high blood glucose and $18.1\%$ hypertension, $27.9\%$ hypercholesterolemia, $8.3\%$ registered abnormal liver functions, and $31.3\%$ were classified as overweight and obese. Moreover, because some vulnerable blood profiles were found in the older age groups, various programs, including nutrition education, and/or development of healthful diets as well as excercise activities, may be needed within their workplaces.
The purpose of this research was to evaluate the correlation between obesity, threshold of salty taste, optimal saltiness and blood pressure in middle school students in a fishing village. The subjects were 115 boys and 103 girls in middle school in a fishing village. The BMI index and systolic and diastolic blood pressures of subjects were measured, and the subjects were divided into a normal and obese group according to their BMI. The threshold of salty taste and salt preference for a semisolid dish (steamed egg dish), liquid dish (bean sprout soup), and a solid dish (raw radish salad), were estimated by sensory evaluation. Calorie intake was measured using the weighing plate method. The boys in the obese group showed significantly higher systolic and diastolic blood pressures than those in the normal, but girls did not. Furthermore, calorie intakes of the boys in the obese group were significantly higher than those in the normal group, but this was not shown in girls. On the threshold of salty taste, both boys and girls in the obese group needed higher concentration of salt than those in the normal group. The threshold of salty taste were significantly positively correlated with systolic pressure and diastolic pressure in boys. Regarding the salt preference in the steamed egg dish, bean-sprout soup, and raw radish salad, both boys and girls in the obese group preferred higher concentrations. The higher concentration they preferred, the higher the systolic and diastolic pressures were in boys, but only systolic blood pressure was higher in girls. From these results, it is evident that a nutritional education program is needed in school to help restricting middle school students salt consumption and decreasing obesity to prevent hypertension.

Objective : The aim of this research was to investigate the depressive effect of acupuncture on Gangap-point and depletion on Taech'u-point in stroke patients. Methods : We measured the blood pressure of the patients who were admitted in the Oriental Medical hopital of Dongeui medical center from 21. Oct. 2001. to 20. Jan. 2002. 19 stroke patients were devided into two groups. 12 patients were treated by acupunctured on Gangap-point. The other 7 patients were treated by depletion on Taech'u-point. The activity of daily living was measured. If systolic blood pressure was over 160 mmHg or diastolic blood pressure was over 90 mmHg, acupunctured on Gangap-point and depletion on Taech'u-point were performed. Then 30minutes and 60minutes later, systolic, diastolic blood pressure and pulse rates were measured Results : After 30 minute treatment. both acupuncture on Gnagap-point and depletion on Taech'u-point significantly depressed the systolic blood pressure. After 60 minute treatment. only depletion on Taech'u-point were statistically significant in depressing the systolic blood pressure. Pulse rates were not significantly changed. Conclusion : These results suggest that depletion on Taech'u-point is more effective in depressing the systolic blood pressure than acupuncture on Gnagap-point.

The finite-field division can be applied to the elliptic curve cryptosystems. However, an efficient algorithm and the hardware design are required since the finite-field division takes much time to compute. In this paper, we propose a radix-4 systolic divider on $GF(2^m)$ with comparative area and performance. The algorithm of the proposed divide, is mathematically developed and new counter structure is proposed to map on low-cost systolic cells, so that the proposed systolic architecture is suitable for YLSI design. Compared to the bit-parallel, bit-serial and digit-serial dividers, the proposed divider has relatively effective high performance and low cost. We design and synthesis $GF(2^{193})$ finite-field divider using Dongbuanam $0.18{\mu}m$ standard cell library and the maximum clock frequency is 400MHz.
The purpose of this study is to find the tracking of blood pressure in primary school-age children. A follow-up study was conducted from 1986 to 1990 on 330 first grade children attending primary schools in Kangwha County, Kyungki-Do. Basically we employed a linear regression model with random coefficients to figure out the relation between blood pressure changes and initial blood pressure. We obtained the following results ; 1. The mean blood pressures were increased grade went up in both sexs and were generally higher in female than male except for the systolic blood pressure at first grade. The size of difference was about 0.8 mmHg in mean systolic blood pressure and 1.5 mmHg in mean diastolic blood pressure. 2. The average annual increasing rates of systolic blood pressure were 2.5 mmHg in male and 3.1 mmHg in female respectively. For the diastolic blood pressure IV the average annual increasing rates were observed to be 3.0 mmHg in male and 2.9 mmHg in female respectively. Increasing rate of systolic blood pressure was significantly higher in female than male. 3. The adjusted regression coefficient of systolic blood pressure change on initial value was -0.11 in male and -0.13 in female and that coefficient of diastolic blood pressure change on initial value was -0.01 in male and -0.11 in female. This result shows that children with higher initial blood pressure do not pick up their blood pressure faster than others with lower initial blood pressure. There is no evidence of tracking of blood pressure in children. It is essential to find the earliest age having the tracking of blood pressure and we leave it for the further study.
For the purposes of analyzing the distribution and the change in blood pressure according to age and determining the factors affecting the change in blood pressure, a follow-up study had been conducted for 6 years from 1986 to 1991 for 430 primary school children aged 6 years old in 1986 in Kangwha County, Korea. The mean blood pressure increased according to age. Specifically mean systolic blood pressure increased from 97.3 mmHg for male and 96.4mmHg for female (at 6 years of age) to 108.8mmHg fur male and 112.1mmHg for female (at 11 years of age). Mean diastolic blood pressure increased from 60.0mmHg for male and 61.8mmHg for female (at 6 years of age) to 72.9mmHg for male and 73.8mmHg for female (at 11 years of age). The average annual increase in blood pressure was 2.3mmHg (in systolic blood pressure) and 2.6 mmHg (in diastolic blood pressure) for male : and 3.1mmHg (in systolic blood pressure) and 2.4mmHg (in diastolic blood pressure) for female, respectively. To determine the factors affecting the change in blood pressure, the stepwise regression analysis was conducted. Children were divided into the three groups(low, middle, and upper) according to the level of systolic and diastolic blood pressure at the age of 6, and the regression analysis was performed in each group. For the change in systolic blood pressure, the changes in weight and skinfold thickness or initial skinfold thickness fer male, and the change in weight for female were selected as significant factors for children in middle and upper group. For the change of blood pressure in diastolic blood pressure, no variables was significant.

A two-dimensional systolic array for fast Fourier transform, which has a regular and recursive VLSI architecture is presented. The array is constructed with identical processing elements (PE) in mesh type, and due to its modularity, it can be expanded to an arbitrary size. A processing element consists of two data routing units, a butterfly arithmetic unit and a simple control unit. The array computes FFT through three procedures` I/O pipelining, data shuffling and butterfly arithmetic. By utilizing parallelism, pipelining and local communication geometry during data movement, the two-dimensional systolic array eliminates global and irregular commutation problems, which have been a limiting factor in VLSI implementation of FFT processor. The systolic array executes a half butterfly arithmetic based on a distributed arithmetic that can carry out multiplication with only adders. Also, the systolic array provides 100% PE activity, i.e., none of the PEs are idle at any time. A chip for half butterfly arithmetic, which consists of two BLC adders and registers, has been fabricated using a 3-um single metal P-well CMOS technology. With the half butterfly arithmetic execution time of about 500 ns which has been obtained b critical path delay simulation, totla FFT execution time for 1024 points is estimated about 16.6 us at clock frequency of 20MHz. A one-PE chip expnsible to anly size of array is being fabricated using a 2-um, double metal, P-well CMOS process. The chip was layouted using standard cell library and macrocell of BLC adder with the aid of auto-routing software. It consists of around 6000 transistors and 68 I/O pads on 3.4x2.8mm\ulcornerarea. A built-i self-testing circuit, BILBO (Built-In Logic Block Observation), was employed at the expense of 3% hardware overhead.
Objectives This study is to investigate the related factors to contribute the metabolic syndrome according to Sasang Constitution. Methods Nine hundred twenty six persons out of 1774 persons, over 40 years old, participated in community-based cohort in Wonju City of South Korea from June 2006 to August 2009. The diagnosis of metabolic syndrome was carried out by NCEP-ATP III(National Cholesterol Education Program in Adult Treatment Panel III) and Asian Pacific Criteria for abdominal obesity. The related factors were checked using questionnaire and blood samples. Sasang Constitution was verified by a Sasang Constitution specialist using the results of PSSC(Phonetic System for Sasang Constitution), facial pictures and simplified Sasang Constitutional questionnaires. Metabolic syndrome incidence rate according to Sasang Constitution and binary logistic regression analysis were performed with SPSS 19.0. Results Metabolic syndrome incidence rate was 30.3% and the majority of newly categorized as metabolic syndrome was Taeeumin(40.7%). There were significant risk factors like systolic blood pressure, fasting blood sugar, triglyceride and female and a significant defense factor like HDL-cholesterol. In terms of constitutional view, there were significant risk factors like waist circumference, systolic blood pressure, triglyceride in Soyangin, female, waist circumference, systolic blood pressure, fasting blood sugar, triglyceride in Taeeumin, female, waist circumference, systolic blood pressure, triglyceride in Soeumin. And there was a significant defense factor like HDL-cholesterol in only Taeeumin. Conclusions Regimens on metabolic syndrome were considered to be changed according to Sasang Constitution. Taeeumin female and Soeumin female should be cautious of body weight and metabolic syndrome when elderly. There are more cautious risk factors in each constitution; systolic blood pressure and triglyceride in Soyangin and fasting blood sugar and serum lipids levels in Soeumin and Taeeumin.

Purpose of this study was to investigate correlation between blood pressure (systolic and diastolic) and dietary sodium, potassium intake pattern in the family members of normal cerebrovascular (CVA) disease, excluding patients themselves. Both mean values of systolic (125.8$\pm$23.7 vs 119.3$\pm$19.2mmHg) and diastolic(76.1$\pm$16.7 vs 71.6$\pm$12.5mmHg) bllood pressure in the family members of cerebrovascular disease patients were significantly higher than those of normal subjects. Systolic blood pressure was positively correlated with age, weibght, sodium in soybean paste, potassium in hotpepepr paste, soybean paste and meats in normal subjects group. In the family members of cerebrovascular patient, systolic blood pressure was possively correlated with age, weight, sodium in soy sauce, drinking water and potassium in soups. Interestingly, table salt intake was positively correlated with systosolic blood pressure in the family members of cerebrovascular disease patients. Diastolic bolld pressure was positively correlated with age, weight, table salt intake potassium in hotpepper paste and soybean paste in normal subjects group. Diastolic blood pressure was positively correlated with age, weight and table salt intake in the family members of cerebrovascular disease patients. Urinary potassium excretion was negatively correlated with both systolic and diastolic blood pressure in the family members of cerebrovascular disease patients.
Objective: The purpose of this study was to investigate the effect of levels of education on ground reaction force and center of pressure parameters during chest compression resuscitation. Method: Twenty male university students were divided into two groups; certified group (CG, n=10) and non-certified group (NCG, n=10). Two force plates were used to measure ground reaction force and center of pressure parameters during 30 times (three trials) chest compression resuscitation. Independent t-tests were used to compare ground reaction force and center of pressure parameters between two groups. An alpha level of 0.05 was used in all tests. Results: All chest-compression time parameters (total time, 1 systolic time, and diastolic time) in CG were significantly shorter than those in NCG (p<.05). Fy of the diastolic and Fz of the systolic in CG revealed significantly the larger GRF values and Fy of the systolic in CG showed significantly the smaller GRF value (p<.05). The standard deviation of Fz of the systolic and diastolic within the subject during 30 times chest-compression resuscitation revealed significantly the smaller values in CG (p<.05). Conclusion: First, CG performed chest compressions efficiently at an appropriate rate compared to NCG. Second, CG showed lower Fx and Fy values in both the mediolateral and anteroposterior axes compared to NCG, which reduced unnecessary chest-compression force consumption and minimized the movement in patients with cardiac arrest. Third, CG showed high Fz value of the systolic and low Fz value of the diastolic. Based on this, chest compression resuscitation was performed to increase the survival rate of cardiac arrest patients.
