This paper is the fuzzy learning control for an unstable and multivariable system used in many cases. Generally, it is very difficult to design the fuzzy controller for an unstable and multivariable system. The reason is that inputs and outputs are coupled and the system is more complex as the number of variables in it increase. To solve these problems we extend Chung's method to the multivariable system and apply it, this method can design fuzzy controller more easily and adapt more actively in work condition changed and obtain the best fuzzy rules. And we apply it to the inverted pendulum. The method which extended Chung's method needs conditions for the system which make stability system in initial time in an unstable system and prove the jacobian matrix of the system the monotonic function. So we make stabilization the system in initial time using 4-dimension fuzzy rules, and we prove the jacobian matrix of the system the monotonic function as experiment. Finally, we operate learning-variables in the fuzzy learning and obtain the optimal controller for inverted pendulum.

Unlike the general lighting systems, stage lighting system requires accurate dimming control and reduction of flicker phenomenon. In this paper, we studied PWM dimming control and linear voltage level control methods. PWM Dimming is easy control and flicker phenomenon of linear voltage level dimming does not happen by experiment result. We concluded that stage lighting dimming system required to combine two techniques of the PWM and linear voltage level dimming control method.

Purpose : This study was to identify intention of hospital revisit and hospital services satisfaction by inpatient. Method : The subjects were 257 inpatients in G city. The data were collected from August 2nd to August 31st, 2004 by structured questionnaire. The data were analyzed using descriptive statistics, x^(2)test. Results : About 86.0% of the subjects had intention of hospital revisit. Decisive factor to choose a hospital was high-tech medical equipments and facilities. Among the factors of hospital services satisfaction, service satisfaction by nurses was in the highest at average marks 3.97. Hospital services satisfaction according to decisive factors to choose a hospital, there were statistically significant differences in treatment effect(x^(2)=9.69, p<.05), kindness of doctor(x^(2)=18.60, p<.00), kindness of nurses(x^(2)=20.55, p<.00). Intention of hospital revisit according to decisive factors to choose a hospital, there were statistically significant differences in excellent medical personnel(x^(2)=4.44, p<.05), tradition and confidence of hospital(x^(2)=5.29, p<.02). Conclusion : If satisfied with hospital services, patients tend to revisit hospital. Therefore it is essentials to raise the satisfaction level with hospital services by analyzing the areas with low services satisfaction in order to increase the competition of hospital.

The Golden Notebook tells the story of Anna Wulf's transformation of personal and political consciousness, and it makes as well a transformation Lessing's artistic identity. With this novel, the writer who once held the view that the realist novel, the realist story, is the highest form of prose writing and higher than and out of the reach of any comparison with the greatest nineteenth writers, suddenly and emphatically rejects both the conventional novel and the modernist novel as model for her own. Seemingly overnight, the traditional novelist becomes not merely a modern novelist, but a postmodern novelist in this view and powerful identity, Lessing reshapes the form of the novel, giving it a postmodern order. Doris Lessing's The Golden Notebook operates on two principle modes, the outer and inner action. Towards the end of the Golden Notebook section that false dichotomy is resolved as Anna participates in practical life by negotiating with an inner voice. The novel consequently requires both linear and non-linear reading. The reader must employ his or her analytic faculties in comparing and elucidating different parts. The aim is the transcendence of the one-dimensional mode of experiencing reality so that a new equilibrium may become possible. The great power of the book comes from the way it interweaves all its levels and combines all its parts into balanced whole. Its structure builds a comprehensive and compelling picture, which fulfils its meaning hough both form and content. The form of Lessing's novel embodies this saving schizophrenia in that a many times split, yet in such a way as to reveal the underlying-saving- shape of one woman's experience. That shape is not a fixed form but a continual movement away from outworn form into chaos and toward new form. Acceptance this creative flus is one of the prerequisites of postmodern art The creation of a text patterned and textured so as to express it is Lessing's triumph in The Golden Notebook.

Generally, most of machining processes are done, according to the dimension of the draft made by CAD. However, there are many cases that a sample is given without the draft because of the simplicity of the shape in the machining of 2D objects. In order to cut the same shape as the given sample, this paper proposes the method to extract the geometric information about a large sample using the robot vision and to draw the dimensional draft for the machining. Because the resolution of one frame in the vision system is too low, it is necessary to set up a camera according to the desired resolution and to capture the image moving along the contour. And the overall outline can be compounded of the sequentially captured images. In the experiment, we compared the product after the cutting with the original sample and found that the size of two objects was coincided within the allowed error bound.

In an attempt to evaluate the cytotoxicity for lidocaine, tetracaine and bupivacaine, beating rates, tetrazolium MTT and lactate dehydrogenase activity were investigated in the medium containing the local anesthetic drugs for 24 hours after the neonatal rat myocardial cells were cultured for 72 hours. Light and electron microscopic studies were also carried out. The results were as follows: 1. Beating rates decreased dose-dependently. and beating myocardial cells were not observed at 10^-3M concentration of tetracaine and bupivacaine, and also beating activities were not recovered after 24hrs. 2. MTT_50 values were 995 μM in tetracaine and 983 μM in bupivacaine. 3. The amount of lactate dehydrogenase released into the medium at 10^-3M concentration were 123% in lidocaine, 156% in tetracaine and 182% in bupivacaine compared with control cells. 4. In the light microscopy, myocardial cells were decreased in number dosede-pendently, and showed a few cytoplasmic processes at 10^-3 M concentration of tetracaine and bupivacaine. 5. In electron microscopy, myocardial cells treated with tetracaine and bupivacaine showed destructed mitochondria and many dense bodies. These results suggest that high concentration of tetracaine and bupivacaine (10^-3M) induce remarkable toxicity compared with lidocaine on the cultured rat myocardial cells.
