This study was performed to evaluate the prevalence of spinal disorders in dogs, as well as their breed, age, gender and body weight distributions. Seventy cases of caine spinal disoreders presented in the period 2001 and 2006 were reviewed. The diagnosis was obtained by survey radiographs, myelogram, CSF analysis, CT and MRI. The most frequent breed was Maltese(15 cases), and followed by Yorkshire Terrier (10 cases), Pekingese (9 cases). Canine spinal disorders occurred from 7 month to 17 year old dog, mean age was 5.3±3.7 year-old. Canine spinal disorders occurred more often in females(59.7%) than males. Mean body weight was 5.87±7.02 kg. Degenerative (39 cases, 43.3%) and anomalous (24 cases, 26.7%) disorders were dominant in 90 specific disease distribution. This results can be a reference data for the further study.

This paper describes the model identification and the discrete-time sliding mode control of electro-hydrauric servo systems which are composed of servo valves, double-rod cylinder and load mass. The controlled plant is identified as a 3th-order discrete-time ARMAX model obtained from the prediction error algorithm, where a nominal model and modeling errors are quantitatively constructed. The discrete sliding mode controller for 3th-order ARMAX model is designed in discrete-time domain, where all states are observed from Kalman filter. The discrete sliding mode controller has better tracking performance than that obtained from continuous-time sliding mode controller, in experiment.

This experiment was conducted to investigate the effect of temperature of extrusion processing on ruminal degradation characteristics of soybean meal. Four ruminally cannulated Holstein cows were employed to in situ trial and treatments were composed of soybean meals untreated(Control), extruded at 115, 130 and 155℃, and treated with 0.3% formaldehyde(HCHO). The nylon bags were suspended for 0, 3, 6, 9, 12 and 24 hours in the rumen, respectively. Animals fed the diet of 50 : 50 in concentrate and orchard grass hay at 110% of NRC(1988) requirements, and were freely access to water and mineral block. The regression equations for degradation characteristics and effective degradability(ED) of crude protein of soybean meals in the rumen were obtained as follows. Control P = 26.41 + 69.86(1-e^-0.041t) ; ED(k=0.05) = 57.89% 115℃ extrusion P = 3.39 + 44.76(1-e^-0.013t) ; ED(k=0.05) = 12.63% 130℃ extrusion P = 2.79 + 56.60(1-e^-0.015t) ; ED(k=0.05) = 15.85% 155℃ extrusion P = 1.71 + 31.48(1-e^-0.018t) ; ED(k=0.05) = 0.04% 0.3% HCHO P = 7.23 + 35.14(1-e^-0.015t) ; ED(k=0.05) = 15.34% where, P = Degradability during the time(t) suspended in the rumen, k = Passage rate at the rumen(%/hr/100). Ruminal degradabilities of dry matter, crude protein, organic matter and energy significantly (P<.01) decreased by extrusion or HCHO treatments, but did not affected by the temperature of extrusion processing. The ruminal degradation of soybean meals treated extrusion and formaldehyde, paticularly crude protein, was low beyond expectation.

This paper studies on the design of a ILQ(Inverse Linear Quadratic optimal control) looper control system for hot strip mills. The looper which is placed between each stand plays an important role in controlling strip width by regulating strip tension variation generated from the velocity difference of main work rolls. The mathematical model for looper is firstly obtained by Taylor's linearization of nonlinear differential equations, where it is given as a linear and time invariant state-space equation. Secondly, a looper servo controller is designed by ILQ control algorithm, which is an inverse problem of LQ(Linear Quadratic optimal control) control. By tunning control gain arbitration parameters and time constants, it is shown that the ILQ looper servo controller has the performance that makes well to follow desired trajectories of both strip tension and looper angle.

This study was analyzed the validity and the reliability of evaluation norm, which was used in choosing and grading events of the General Motor Ability Test. The General Motor Ability Test has been done for applicants for entrance to the department of physical education, college of education, Pusan National University. The subjects of this study were 200 applicants(men : 159, women : 41) for three years (1999-2001). They were tested in six events : 1) 100m Dash, 2) 1500m Run (men), 800m Run (women), 3) Wall Bound Pass, 4) Chinning(men),Push Up(wonen), 5) Zig Zag Run, 6) Trunk Flexion. The results could be summerized a s follows: 1. For women, their average records were shown normal distribution in 100m Dash. 1500m Run and Trunk Flexion. But in Wall Bound Pass and Chinning, their records were distributed over two extreme poles. Therefore it's necessary to regulate the interval sizes and rules of Wall Bound pass and Chinning. The interrelation between events were generally reliable. Between 100m Dash and Wall Bound Pass, and between Wall Bound Pass and Chinning are mutually related. so more studies must be done. 2. For women, their average records were shown normal distribution in 100m Dash, 800m Run and Trunk Flextion, too. But the interval sizes of Zig Zag Run. Push Up must be adjusted to higher. Also it's necessary to regulate the interval sizes and rules of Wall Bound Pass like men's instance. it's impossible to analyze correctly interrelation between events because of the small number of subject. From the analysis of the General Motor Ability Test, we could realized the necessity of regulation the standard and interval sizes in several events : Wall Bound Pass and Chinning for men, all events especially Wall Bound Pass for women.

Objectives : There are a number of preceding epidemiological studies reporting gender differences in the genetic etiology of alcohol dependence. The author investigated gender difference in the frequencies of ADH2 and ALDH2 genoypes between the patients with alcohol dependence and normal control. Methods : The subjects were 141 alcohol dependent patients (104 males, 37 females) and 138 normal control (79 males, 59 females). The frequencies of 1/1 and 1/2+2/2 (2+ afterward) genotypes for ADH2 and ALDH2 were investigated in male and female between alcohol dependence and normal control group. DNA was extracted from WBC in peripheral venous blood and PCR-RFLP method was used out for genotyping. Results : First, the frequency of ADH2 1/1 genotype was significantly higher in alcohol dependent patients than normal control in both genders. Second, while there was no gender difference in the frequency of ADH2 1/1 genotype in normal controls, in the patient group however, the frequency was significantly higher in females than males. Third, in male subjects with alcohol dependence, the frequency of ALDH2 1/1 genotype was significantly higher than in male normal control subjects. On the other hand, in female subjects with alcohol dependence, the frequency of ALDH2 2+ genotype was significantly higher than in female normal control subjects. Conclusion : These results suggest that while the risk of alcohol dependence is predominantly affected by ALDH2 1/1 geno-type in male, the female ADH2 1/1 genotype is mainly associated with the risk of alcohol dependence. This means that there are gender differences in the genetic etiology of alcohol dependence.

Appendicitis is the most common acute abdomen in Emergency Medical Center & outpatient department. But sometimes, it is difficult for us to diagnose because of clinically variable symptoms. We reviewed the ultrasonographic findings and analyse 521 cases of appendectomy patients about its distribution of sex and age, seasonal prevalence, clinical symptom and signs, laboratory findings, duration from onset of symptom to arrival at hospital, duration from arrival at hospital to operation, vital signs, operative results, and associated diseases, which were treated at the department of General Surgery & Emergency Medical Center in Chung Ang Gil Hospital from July, 1994 to June, 1995. The results were as follows : 1. The most common age group was second decade. And male to female ratio was 1.43:1. Seasonal variation was not significant. 2. Of 521 cases, 141 cases(27.1%) visited the hospital within 24 hours from the onset of symptom, and 259 cases(49.7%) visited between 24 to 48 hours. 3. In duration from arrival to operation, the cases within 6 hours were 263 (50.5%), the cases between 6 and 12 hours were 131(25..1%). 4. In systolic blood pressure, cases below 90mmHg were 19(3.6%), cases above 160mmHg were 23(4.4%). Below 60mmHg diastolic pressure were 55 cases(10.6%), cases above 110mmHg were 9(1.7%). In pulse rate, above 90 rate/min were 171(32.8%). 5. On admission leukocytosis was found in 413 cases(79.3%) and 342 cases of them were pathologic appendicitis. 6. Ultrasoundgraphy was performed in the 87 cases, but 23 cases were suggested appendicitis. Among 23 cases, 22(95.7%) revealed pathologic appendicitis at ooperation and labortatory examination. Of the 64 cases which were normal on ultrasonography, only 2 cases(3.1%) were proved to be appendicitis. 7. The results of 496 operations without ultrasonography were appendicitis in 390 cases(78.6%), mesenteric lymphadenopathy 36(7.3%), pelvic inflammatory disease 28(5.6%), fecalith 15(3.0%), terminal ileitis 8(1.6%), diverticulitis 7(1.4%), urinary tract stones 5(1.0%), cecal cancer 2 cases, right ovarian tumor 2 cases, tubo-ovarian abscess 2 cases, grater omentum internal hernia 1 case. Our results showed that the sensitivity of ultrasonohraphy was 95.8% and the specificity 98.4% in the diagnosis of appendicitis, It suggests that the ultrasonography is very helpful in the diagnosis & differential diagnosis of acute appeendiditis.
