Invasive methode and Non-invasive methode are used in blood pressure measurement. The Invasive methode can Set the correct measured blood pressure but, it has patient feels uncomfortable. So most of cases use Non-invasive methode. The Oscillometric method is commonly apply to modem electric sphygmomanometer and using various algorithm. In this paper describe about a algorithm it control and to determinate the cuff pressure, and filtering that data for measure the blood pressure. The communicating with personal computer can pressure deflation is by Solenoid valve and it uses RS-232 system in packet communication. The main using algorithm for blood pressure measurements are maximum amplitude algorithm and oscillometric algorithm. MAA(maximum amplitude algorithm) has various measured oscillation it depend on patient's age, height, weight and arm circumference size. In this paper, 1 studied the various measured oscillation apply to characteristic ratio and can get the result of systolic blood pressure, diastolic blood pressure, mean blood pressure. It was not used same ratio to measuring oscillation. In the MAA(maximum amplitude algorithm), we hope for reduce the difference with the real blood pressure and the measured blood pressure, when it applied with various specific ratio.

A nutrition survey of 198 children, 6 to 12 years old, in the Song Myeon Elementary School and Sam Song Elementary School, located in remote villages of Gaesan county, Chung Buk province, was undertaken between July 11 and 16, 1988, to investigate dietary and nutritional status. Mean values of height, weight, sitting height, arm circumference, girths of chest, and weight for height were 98%, 96%, 101%, 94%, 103% and 98%, respectively, of Korean standards. Compared with the standards for Korean children and values for Yun Jung Elementary School children of Youido, Seoul, anthropometric data of subjects surveyed showed slightly lower results than the standards and further lower results than those of Yun Jung Elementary School children. mean hematocrit value was 39.8±3.1%. 15.3% of subjects were proven to be anemic according to the hematocrit criterion established by the WHO. Mean urinary urea nitrogen/creatinine ratio was 7.9±3.3. Energy and nutrient intake were 61.2 to 134.4% of the RDA's; except for intake of ascorbic acid, most nutrients were below the RDA's. Carbohydrate provided 72% of total energy intake; protein accounted for 11%; fat provided 17%. Family environment, anthropometric data and results of biochemical tests were positively correlated with nutrient intake. The survey emphasizes the need for a nation wide school lunch program.

Objective : The purpose of this study was to investigate the characteristics of Gam-ki (double-arm winding) depending on the emotion being expressed. Gam-ki is one of the basic movements of Korean traditional dance. Method : We selected three Korean traditional dancers who belong to National Dance Company of Korea. They were asked to express four different emotions (anger, joy, sadness, and neutral) while performing Gam-ki. We analyzed elapsed time and time ratio, size of movement, ground reaction forces and ground impulses. Results : During Gam-ki the elapsed time for each phase as well as for one cycle was longest when "sadness" was expressed then followed by "neutral" and then "angry" and "joy." Except for the ankle in/eversion, the ROMs of the lower limb joints seem not to be an emotion-characteristic factor. The ROMs of the upper limb joints were largest when "anger" was expressed. Neck rotation is associated with expressing negative emotions ("angry" and "sadness"). For medial-lateral GRF "angry"> "joy" > "neutral" > "sadness" was in order. Therefore, it can be regarded as a factor indicating the activity of the emotion.

This study was carried out to identify the chromosome morphological structure and G-, C-banding pattern of Korean native fowl. The samples used in this study were early chick embryos, and the method of chromosomal analysis quoted from the protocal of Ohio univ. with more or less modified. The results were summerized as follow as； 1. In each of macrochromosomal morphology, the arm-ratio, centromeric index, and relative length of Korean native fowl were more or less different from improved breeds, but the designations were the same. 2. The graphical pecks, by densitometric recordings, in each macrochromosome number of 1, 2, 3, 4, Z, and 5, numbered 21, 14, 12, 8, 11, and 4 in G-banded, and 16, 13, 9, 9, 9, and 4 in C-banded, respectively. Those pecks could be explained as a consequence of chromosome condensation during mitosis and of genetic material differences.

Purpose: The primary objective of this research is to propose answers of rider's accident of food retailer in South Korea, in view of business sustainability of food retailer and his precious fate of rider who is a father that has a responsibility to the family. Research design, data, and methodology: We investigated previous studies such as food retailer, delivery, delivery application of mobile, rider's accident and statistics of delivery business agency, motorcycle accident ratio, annual fatalist, and further we analyzed cases of rider's accidents. Results: Rider's accident on the road toward food retailer is serious risky factor to their business reputation, corporate image, because claim amount related to death and physical/mental disability can be heavily damaged to food retailer. The point when rider dies is that rider is a person responsible for supporting his/her family, that is, a life itself issue together with downfall of family. Conclusions: In view of growth of South Korean' delivery rider industry, the authors recommended that focus of stability and sustainablity of both food retailer and delivery rider should establish to executable and practical ideas such as rider's readiness, abandon of speed guarantee, duty of delivery app business and legal aids.

Objectives : Atopic dermatitis(AD) assume an remarkable clinical aspect and it s diagnosis almost depends on clinical symptoms. Therefore, we aimed to study the clinical diagnostic standard of AD for more accurate treatment. We repert as follows; Methods : For 6 months from March to August in 2000 we selected fifty outpatients who were prognosis of AD in the department of dermatology, Oriental medical hospitol, Dong-eui University. Results and Conclusions : 1. We classified of the grade, the condition of AD patient was slight and severe, by the sum of total by the clinical index of AD (diagnostic features). 2. By consulting previous oriental medical theories, we divided symptom-complex of AD into two type ; one was damp-heat type and the other was deficiency of blood- wind-dryness type. 3. Male to female ratio was 17 : 33 and the third stage, more than half of the patients were adolescents. 4. According to the results of symptom-complex of AD patients, on the first examination damp-heat type was more than deficiency of blood-wind-dryness type and in progressing treatment, the condition has been change to deficiency of blood-wind-dryness type. 5. In the lesions of AD, arm and knee were most serious skin lesions and in symptoms of AD, pruritus was most complained, and in progressing treatment, erosion and erythema were greatly improved. 6. When we measured the levels of serum Total IgE, that of thirty eight patientswere higher than that of normal, but elevation of serum IgE levels was not correlated with the severity of AD.

Purpose: This study was conducted to measure adiposity and to investigate related factors in preschoolers born prematurely. Methods: A longitudinal follow-up study was conducted with 52 preschoolers at 5 years of corrected age among 343 preterm infants. Their adiposity status was evaluated based on measurements of body mass index, subscapular and triceps skin fold thickness (SFT), waist circumference, waist-to-height ratio, and mid-arm circumference at a home visit. Results: The findings showed that SFT measurements, particularly at the triceps, reflected the degree of adiposity more accurately than other conventional measures. A shorter gestation, older maternal age, and the mother having more years of formal education were associated with higher levels of adiposity in the preschoolers. Conclusion: The adiposity of children born prematurely needs to be thoroughly monitored with additional SFT measurements, considering the risk of accelerated growth patterns overriding regular catch-up growth in children born prematurely.

The purpose of this research is to suggest data available for being conducive to establishing a marketing strategy such as size of domestic clothing in global brand and producing a product of increasing consumers' satisfaction with the fit based on this research. A total of 177 questionnaires obtained from South Koreans in their 20s~50s who dwell in the state of North Carolina in America. The results follow; first, what there is significant difference in clothing purchase behavior of Koreans living according to income, duration of residence. Second, the reason for preferring Korean clothing according to educational level was the highest in the ratio of the response as saying of being 'size' with a decrease in the item of 'design'. This was because the higher in age and educational level leads to the more rise in importance of size according to a change in body type. Third, the outcome of evaluation on the fit by body part in American clothing was the largest in the response as saying of being 'similar' in the items of chest, waist, neck, arm, wrist circumference and crotch length.

In the field of prosthesis arm control, tile pattern classification of the EMG signal is a required basis process and also the estimation of force from col looted EMG data is another necessary duty. But unfortunately, what we've got is not real force but an EMG signal which contains the information of force. This is the reason why he estimate the force from the EMG data. In this paper, when we handle the EMG signal to estimate the force, spatial prewhitening process is applied from which the spatial correlation between the channels are removed. And after the orthogonal transformation, which is used in the force estimation process the transformed signal is inputed into the probabilistic model for pattern classification. To verify the different results of the multiple channels, SNR(signal to noire ratio) function is introduced.

This research described dynamic scapulohumeral rhythm though the measurement of inter relationship between humorous and scapular movement during elevation of the arm in the scapular plane. In the previous studies static plane film X-ray has usually been used, but the limitation of such method was that it did not show the real· movement. In this study, we investigated real movement of humorous and scapular bones by Digital fluoroscopy system. 1. In resting position, humorous was taken to lie at the average $5.97^{\circ}$ in abduction, and scapular at the average $3.66^{\circ}$ in internal rotation. 2. At the maximal abduction, humorous was abducted to the average of 181.25", and scapular was rotated externally to $51.43^{\circ}$. 3. This research has shown that there is a variety of scapulohumeral rhythm from resting position to $60^{\circ}$ abduction in elevation of humorous. This case study demonstrated that the ratio n of scapulohumeral rhythm is 3.46 to 1, but there was individual difference.
