Carcinous pain is severe and continuous so difficult to alleviate. Western drugs give rise to reaction such as anorexia, constipation, vomiting, general weakness and dyspnea, And they cause tolerence. External treatment is a way to put a patch or rub a liquid on the skin. The patch and liquid are made from herb medicine. In china, they have a good effect of alleviating carcinous pain to make use of external treatment. Usually they use the medicine with effect of reprecussion (消腫), removing obstruction(散結), activating blood flow and removing blood stasis (活血化瘀) such like Borneloum(?片). Bufonis Venenum (蟾?), Aconiti ciliane Tubber(草烏), Arisaematis Rhizoma(南星), Asari herba cum Radice (細辛) etc. We can get the alleviating effect more quickly and prevent reaction through external treatment.

An economical 4-axis CNC controller employing step motors is designed and implemented in this paper. By using the inherent ability of holding position of the motor, the CNC controller uses open-loop control for removing trajectory error and for a simple hardware. Each drive of axis has an 8-bit microprocessor 89C52 and a PC controls the axes and pendant by means of RS232C serial communication. Backlash is also compensated at the axis controller. While compensating the backlash, the feed rate becomes zero in order to minimize trajectory error. The trajectories of 16ms interval are computed on PC and are sent to motor drives. In the drives, the trajectories are linearly interpolated for 2ms interval. The developed CNC does not require add-on specific motion card on PC. From the experimental results, the validity of the CNC controller based on step motor is proved.

In this paper, speech quality is improved by removing abrupt noise intervals and then substituting the gaps with estimates of the previous speech waveform. An abrupt noise detection signal has been proposed as a prediction error signal by utilizing LP coefficients of the previous frame. Abrupt noise intervals are estimated by using spectral energy. After removing estimated noise intervals, we applied several waveform substitution techniques such as zero substitution, previous frame repetition, pattern matching, and pitch waveform replication. To prove the validity of our algorithm, the LPC spectral distortion test and the recognition test are executed and, the results show that the speech quality is fairly well improved.

Decapsulation technology is useful to inspect EMC of package device and the etching technology enable to check inside of device by removing plastic molding. Chemical etching method is used widely to fabricate a lot of semiconductor. But the method has some disadvantage due to wet process. Proposed method in this paper shows the application possibility such as fast processing time, processing accuracy and dry process. These result was obtained by directly removing of packed EMC using UV laser.

Typically, manganese (II) ions are incompletely removed from water as $MnO_2$ on increasing the pH of the water to 10. The water then has to be neutralized before it can be used. We propose a new and effective method for removing Mn (II) from water using a new combination of symbiotic microbes consisting of manganese-oxidizing bacteria and filamentous algae. The microbes rapidly oxidize Mn(II) to Mn (IV) at a neutral pH with no organic matter required as a nutrient and $MnO_2$is precipitated immediately. This differs from the use of heterotrophic manganese-oxidizing bacteria where organic nutrients are required. Our results suggest that this method will be useful in developing new systems for removal of manganese(II) ions from industrial and mining wastewater and drinking water. In addition, there are other possibilities such as recycling of dry batteries which are presently discarded without treatment

Flow defect of a piston-pin for automobile parts is investigated in this study. In combined cold extrusion of piston-pin, lapping defect, which is a kind of flow defect, appears by the dead metal zone. This appearance evidently happens in products with a thin thickness to be pierced for the dimensional accuracy and the decrease of material loss. The flow defect that occurs in piston-pin has bad effects on the strength and the fatigue life of piston-pin. Therefore, it is important to predict and prevent defects in the early stage of process design. The best method that can prevent flow defect is removing or reducing dead metal zone through material flow control. The finite element simulations are applied to analyze the flow defect. This study proposes processes for preventing flow defect by removing dead metal zone. Then the results are compared with the experimental ones for verification. These FE simulation results are in good agreement with the experimental ones.

Electrohydrodynamic jet printing (EHDP) technique is widely used for the direct writing. However, in the existing EHDP method, the printing characteristics are affected by the printing substrate used, and the line width of the printed is determined by the geometry of the nozzle. We propose an EHDP method which is capable of (1) removing the effect from the substrate, and (2) controlling the line width through the ON/OFF control of the each nozzle in the nozzle array. Printing characteristics of our EHDP system were examined and successful ON/OFF control of the nozzle array were demonstrated. By using the proposed EHDP, it is expected that stable meniscus regardless of the substrate and different line widths even using the same nozzle can be achieved.

A literature study was progressed for oriental medical treatment for atopic dermatitis. Atopic dermatitis is a chronic or chronically relapsing, pruritic dermatitis. In oriental medical treatment is classified into the treatment of inside(herb tea), treatment of outside(medicine for external application), treatment of inside & outside. The method of inside treatment is improving in health for the spleen and clearing wetness(健脾利濕), extinguishing wind and refreshing fever(消風淸熱), nourishing blood and making dryness gloss(養血潤燥). The method of outside treatment is refreshing fever and removing wetness(淸熱燥濕), counteracting the poison and getting rid of itch(解毒止痒), removing the boil and forming proud flesh(消腫生肌). The method of inside & outside is improving in health for the spleen and clearing wetness(健脾利濕), refreshing fever and getting rid of itch(淸熱止痒). refreshing blood and extinguishing wind(凉血祛風).

Signifying clothes can be defined as a process in which a clothes obtains a symbolic meaning by confining its use and purpose. In this paper we catagorize the process of signifying clothes that appears in the Byongkut as follows : first removing the clothes, secondly putting on the clothes, and thirdly burning off the clothes. Removing the clothes is a process of dramatic realization and clearly shows proven facts about the things that will occur in the process. Putting on the clothes is a process of falsified expression in which the interest is transferred from the person who wears the clothes to the clothes itself by the shaman's insinuation who leads an interpretation about the clothes. Buring off the clothes is a pro-cess of mystification in which the end of Byongkut is sublimated mistiriously by making the partici-pants believe with the burning that the clothes and the diseases have been curred, and therefore, the ritual is kept from spoiling. The clothes used in Byongkut that religious belief and belief system are expressed through behavior style, and that supernatural power is designed to reveal is related with the various aspects of symbolic life indicated by the clothes.
