Yeast infection is commonest fungal infection of human. And their incidence becomes to be increased as the frequency of altered host immune system is increased. Antibiotics, cytotoxic drug, malignancy, diabetes mellitus, operative procedures and catherizations are predisposition of fungal infection. Since antifungal drug within a selective or narrow range of activity are available, it is important that speciation of yeast in routine clinical microbiology practice should be effected rapidly and reliably. Author isolated 159 strains of yeast and that were identified by API 20C Auxanogram®. Patient charts were reviewed retrogradely in order to find predisposing factors of isolated yeast cells. Yeast isolation is 1.8(102:57) of male to female rtio and is more frequently below 1 year-old and above 30 year-old in both sexes. Septum(49.1%). urine(40.3%) were major specimens in which yeast isolated.

本 論文에서는 直交補剛平板에 純粹비틀림 모우멘트를 가하여 보강평판의 비틀림 剛性을 實驗的으로 解析하였다. 實驗은 2点支持 - 2点荷重 및 3点支持 - 1点荷重 方法으로 비틀림 모우멘트를 가하고 板의 中央点 및 荷重点의 처짐과 하중을 測定하여 비틀림 剛性을 구하였다. 두 實驗方法을 比較한 결과 後者의 方法이 정학하고 간단한 방법임을 알았다. 實驗의 정당성을 입증하기 위한 等方性平板의 비틀림 剛性의 측정은 理論값과 4% 이내로 잘 일치하였다. 補剛平板의 비틀림 剛性을 측정한 實驗값은 力學的 相互作用을 고려한 이론값과 비교적 잘 일치하며 補剛材 의 폭이 좁고 높이가 높을 때에는 14%의 오차를 보였다. The torsional rigidity of orthogonally stiffened plates is experimentally investigated by applying the pure twisting moment to the stiffened plate. The 2 point supporting-2 point loading condition and the 3 point supporting-1 point loading condition are employed to measure the loads and deflections at the center and loading points of the plate. The torsional rigidity is obtained from the experimental equation through the load-deflection slope. Comparing the above two experimental conditions, the 3 point supporting-1 point loading condition is found as a simple and accurate state in measuring the torsional rigidity. When compared with theoretical value for unstiffened plates, the experimental results performed for the validity of the two conditions show good agreement within 4%. For the orthogonally stiffened plates, the experimental result show relatively fair agreements with the theoretical values in which the mechanical interaction between plate and stiffener is considered. But, if the stiffener width is relatively narrow and the stiffener height increases, the deviation are in the range of 14%.

In this paper, it is presented a new approach to the design of intelligent control system of a autonomous robot with two drive wheel. The proposed control scheme uses a Gaussian function as a unit function in the fuzzy neural network, and back propagation algorithm to train the fuzzy neural network controller in the framework of the specialized learning architecture, It is proposed a learning controller consisting of two neural network-fuzzy based on independent reasoning and a connection net with fixed weights to simply the neural networks-fuzzy. The performance of the proposed controller is shown by performing the computer simulation for trajectory tracking of the speed and azimuth of a mobile robot driven by two independent wheels

In spite of the use of Bee Venom aqua-acupuncture in the clinics, the scientific evaluation of effects is not enough. Bee Venom aqua-acupuncture is used according to the stimulation of acupuncture point and the chemical effects of Bee Venom. The aims of this study is to investigate the analgegic effects of the Bee Venom aqua-acupuncture, through the change of writhing reflex and the change of c-fos in secondary neurons in the spinal cord. Materials and Methods : Pain animal model was used acetic acid method. The changes of writhing reflex of the mice which were derived pain by injecting acetic acid into the abdomen, after stimulating Bee Venom aqua-acupuncture on Chungwan(CV12) were measured. We used Fos immunohistochemical technique to study the neuronal activity in the spinal cord. Results : 1.Expression of c-fos in superficial dosal horn(SDH), nucleus proprius(NP) and neck of dorsal horn(N) on 6~9th thoracic spine decreased significantly at 2.5×10-4g/kg Bee Venom aqua-acupuncture, compared with saline-acetic acid group. 2.The numeral change of Fos-LI neurons on the NP, N, and ventral gray(V) on 6~9th thoracic spine, SDH on 9~11th thoracic spine, and SDH and V on 11~13th thoracic spine decreased significantly at Chungwan(CV12) Bee Venom aqua-acupuncture, compared with saline-acetic acid group. 3.The correlation between the numbers of writhing reflex and Fos-LI neurons in T6-13 segment was statistically statistically significant at Chungwan(CV12) Bee Venom aqua-acupuncture. Conclusion : This study shows that the Bee Venom aqua-acupuncture on Chungwan(CV12) decreases the numbers of Fos-LI neurons. As the analgegic effects of Bee Venom aqua-acupuncture is recognized. Bee Venom aqua-acupuncture treatment is expected for pain modulation. In order to use it in many ways. more researches are needed for the dose and stability of Bee Venom aqua-acupuncture.

In this dissertation a novel speed control system that implements the fuzzy logic controller(FLC) is proposed. The proposed FLC used the speed error its rate of change, and the drive current as three fuzzy variables. The real command output current is chosen by the defuzzification of fuzzy output extracted from the fuzzy control rules. The flex and the torque of the induction motor are estimated using the dynamic model with an excellent dynamic response over a wide speed range and with the rotor flux field-oriented scheme of the decoupling characteristics The performance of this control system is substantiated by computer simulations.

Purpose : Determination of urinary concentration in neonate is mandatory for precise management of fluid and electrolyte requirements. Although measurement of urine specific gravity has been proposed far monitoring fluid requirements, the reliability of specific gravity does not accurately predict urine osmolalities in the neonate period. So specific gravity should be checked by measuring the osmolality. Also the urinary excretion of creatinine has been used for the assessment of hydration state. We present the result of specific gravity, urine osmolality, urine creatinine in a spot urine sample during the first week of life as a reliable reference standard. Methods : Spontaneously-voided urine sample were obtained in 40 full term neonates. Two urine samples were available with a interval of 4 to 7days (A: 1st day, B: 4 - 7days), Urine sample was tested for specific gravity with a strip test. Also urinary osmolality, urinary creatinine, urinary creatinine/osmolality ratio were measured. Results : The mean of specific gravity tested by the strip test was 1.006±0.0040 (A) , 1.005±0.0036 (B). The mean of urine osmolality and creatinine were 177.7 ± 103.0 and 30.9±21.6 (A), 145.7 ±90.3 and 26.4± 17.7 (B). The mean of excretion rate of urine creatinine/osmolality ratio was 18.2 ±8.5 (A), 19.4 ±9.1 (B). There was correlation between urine specific gravity and osmolality in neonate(r=0.833(A), 0.842(B) p<0.001). Urinary creatinine/osmolality levels of the first urine samples were closely correlated with the second samples (r=0.617, p<0.001). Conclusion : Specific gravity of urine was enough to predict the osmolality in neonate. But Specific gravity should be checked by measuring the osmolality of urine. Urine osmolality and creatinine were spread over a wider range and did not used to urinary excretion of solute in neonate. Urinary creatinine/osmolality ratio can be used to standadise the urinary excretion on solute in the first week of life.
