Clinically healthy Korean adult cattle (20 females and 20 males) were selected and subjected to the experiments on the determination of erythrocytes and total leukocytes values at the stages of pre and post-slaughting. Throughout the studies the following results were obtained. 1. The erythrocytes values, at the stage of the pre-slaughter, of females and males were $6.070{\times}10^6/cmm$ and $6.175{\times}10^6/cmm$ respectively. In the case of post-slaughter stage, $7.780{\times}10^6/cmm$ and $7.705{\times}10^6/cmm$ were obtained for female and male respectively. In comparison on the values of erythrocytes between pre and post-slauglnter stages, the mean value of the latter has been increased significantly. 2. The total leukocytes value, at the stage of the pre-slaughter of females and males were 9,525/cmm and 9,630/cmm respectively. In the case of post-slaughter stage, 7,545/cmm and 7,510/cmm were obtained for females and males respectively. In comparison on the values of total leukocytes between pre and post-slaughter stages, the mean value of the latter has been decreased significantly.

Cleft palate or velopharyngeal incompetence shows many disorders and disabilities affecting speech transmission. including distortion. substitution. and the nasalization of the vowels. The nasalized vowels are produced primarily by lowering of the velum. resulting in opening a side passage for the air flow through the nasal cavity. These abnormal movements give rise to complex modification of the physical property of the sound or in the sound spectrum. The authors employed Sonagraph$^{\circledR}$ as a sound analyzer in order to ascertain the features which characterize the nasalization of vowels. Twenty healthy Korean male adult voluteers were analyzed in artificial conditions of anterior and posterior nasal obstruction. and velo-pharyngeal incompetence. The results were as follows : 1) Fundamental frequency was not changed by nasal obstruction or velopharyngeal incompetence. 2) There was no significant difference of the formant intensity between normal and nasal vowels. 3) In VPI, a decrease of the frequency of $F_2$ was observed in /e/ and /i/ vowels(p<0.001). 4) In VPI, the $F_2$ was frequently missed in /o/ and /u/ vowels. 5) In the consonant spectra of VPI, the 'release burst' was usually not observed.

Bovine abdominal fat necrosis (lipomatosis) is relatively common disorder in adult Korean indigenous cattle. Thirteen Korean indigenous cattle with bovine lipomatosis and five clinically healthy cattle were selected and serum biochemical profiles were analyzed. Serum free fatty acids level was significantly high, while total cholesterol, serum albumin and total calcium levels were significantly low in bovine lipomatosis group. In a case of necropsy, saponificated adipose masses surrounding colon was observed and hepatic fatty degeneration and fat deposition in the renal tubules were found in a histopathologic examination. These findings indicate that affected cattle have a predisposition to deposit more fat into adipose tissue than normal cattle. Such abnormalities might lead to the development of abdominal fat necrosis with fibroplasia and possibly compress the intestines and urinary organs.

Epidural morphine provides excellent analgesia for the management of postoperative pain, but nausea and vomiting are a commonly reported side effect. Scopolamine, a belladona alkaloid, is an effective antiemetic when nausea is induced by morphine. Transdermal scopolamine patches have the advantage of delivering a constant low dosage of the drug over a prolonged period. To evaluate the efficacy of prophylacitic transdermal scopolamine in reducing nausea or vomiting associated with postoperative epidural morphine analgesia, I studied 60 healthy adult patients. The patients were divided into 3 groups, each group consisting of 20 patients. Group 1; no scopolamine for control Group 2; transdermal scopolamine placebo patch Group 3; transdermal scopolamine patch All patients were anesthetized by epidural injection of 2% lidocaine 15 ml and 0.5% bupivacaine 10 ml with morphine 4 mg. A Comparison with the control group, the placebo group, and Group 3, indicated, that the transdermal scopolamine reduced the incidence of nausea or vomiting associated with postoperative epidural morphine analgesia (group 1; 35%, group 2; 25%, group 3; 10%). However there were no statistically significant differences between groups at a level of p>0.05.

A sensor and measuring system were implemented to measure both uroflow and urophonography signal during urination for diagnose the BPH(benign prostatic hypertrophy). The implemented system was composed of the uroflow sensor using the load-cell, the urophonography measurement sensor so as stethoscope type, pre-processing part for sensors signal detection, amplifier and filter, system control parts and PC measurement program. A simulator of the lower urinary system that is experimental equipment implemented for evaluates the developed system. The two signals were measured using implemented system and analyzed these signal by means of time domain and frequency domain for extraction of the characteristic parameter which can most effectively reflected by the occlusion of the lower urinary system. Furthermore two signals were measured and analyzed with the subject of 5 healthy adult for clinical application possibility of the implemented system. As a result, the most influence bandwidth of effect according to occlusion of the lower urinary system is $253{\sim}282Hz$ of the urophonography signal.

Airflow in the nasal cavity of a normal Korean adult is investigated experimentally by tomographic PIV measurement. Knowledge of airflow characteristics in nasal cavities is essential to understand the physiology and pathology aspects of nasal breathing. Several studies have utilized physical models of the healthy nasal cavity to investigate the relationship between nasal anatomy and airflow. All of these researches on nasal airflow are under the condition of constant flow-rate. In this study, nasal cavity flow with the physiological period is investigated by tomographic PIV, for the first time. A pumping system that can produce the periodic flow is created. Thanks to a new method for the model casting by a combination of the rapid prototyping and curing of clear silicone, a transparent rectangular box containing the complex nasal cavity can be made for PIV, The CBC PIV algorithm is used for analysis. Phase-averaged mean and RMS velocity distributions are obtained for inspirational and expiration nasal airflows. The comparison with the constant flow case is appreciated. There exist many flow patterns depending on each phase.

The purpose of this study was to develop a system dynamics model for management of glucose metabolism disorders that demonstrated dynamic relationships between insulin and plasma glucose levels over the time. The model was developed to 1) represent the physiology of glucose metabolism for an normal adult subject, 2) to draw causal loop diagram that demonstrate feedback systems of glucose regulation in normal condition and pathologic condition of the type 2 diabetes, 3) to develop an interactive computer simulation model for management of glucose metabolism disorders. The simulation results showed the plasma glucose level for normal persons varied from 75 to 140 which was consistent with clinical findings. As an example for patients we selected a case which varied from 110 to 310. Two types of interventions were chosen to review the model; meal control and insulin administration. The simulation results for those cases also matched well with clinical findings. The developed model can be used as an effective educational tool for patients to develop healthy lifestyle choices. The results also provide a blueprint for health providers to maintain normal blood glucose levels in diabetes patients.

The purpose of this study were to determine the changes between pre, during, intermed, post of each two groups of 16 persons and to compare the effect of transcutaneous electrical nerve stimulation(TENS) at shenmen of auricular point on experimental pressure pain and tactile threshold measured at both ulnar styloid process and medial malleoli. Sixteen healthy adult men and women, aged 20 to 28 years, were assigned randomly to eight of one groups. Control group received TENS to exception of auricular point. Experimental group received TENS to shenmen of auricular point. Experimental pressure pain and tactile pain threshold at the both ulnar styloid process and medial malleoli was determined with algometer and von frey filament before 10 minute, during 10 minute, intermediate and post 30 min of treatment. In pressure pain and tactile threshold showed a statistically significant increase(p<0.05) ipsilateral and contralateral of treatment group. These results suggest that TENS at shenmen of auricular point has the capability to higher pressure pain and tactile threshold in whole body.
