With the development of industrial society, the interest of new material is growing even in machining center. Composite materials in the new materials are superior to the metals In measure stability of strength, modulus and heat, moreover when mould is prepared, it can be done net shape manufacturing so it can be used widely in all sorts of machine parts, interior materials of car structural construct ions, the space aerial industry, ship materials, sports goods and so on. Therefore in this study, the property of processing drill on CFRP in composite materials by experimental study and some problems were examined.

The root of Rumex crispus(Polygonaceae) has been used as one of many oriental medicines ofr the treatment of cathartics, juandice and skin diseases etc. Recently, it is reported as one of anticancer agents and a remedy of acute hepatitis in many traditional medicines. Also, the seed of this plant has been used as a folk medicine for the treatment of digestion problems, liver diseases and many sorts of tumors. In this study we have collected the seed of this plant in rural area and investigated the efficacy of hepatoprotective activity from liver cell damage induced by carbon tetrachloride on mice with methanol extracts, ethylacetate and butanol fractions of this plant

In this paper, collapse test of thin-walled structural member widely used for automobiles is carried out under static compression load to observe the effects of cross- sectional shape and material on the energy absorbing capacity in the viewpoint of cras- hworthiness. Specimens tested consist of two sorts(Aluminium, CFRP) and configur- ations(Circular, Square) with variation in thickness. Also, comparisons of Al circular and square specimens are made to find the influence of difference in shape on the energy absorbing capability according as the thickness of specimen varies.

Many kinds of methods for the psychological treatments are performed which are differentdepending on the patient's condition and the clinical character. Therefore, a great deal of good effects can be expected by the intention or knowledge of the carrer, although the patients are under the same symptom. The symptom of pain can be given different meanings considering the professional knowledge. It's the same case when the very same psychological condition can be iudged differently and the way of being treated can be variable. The physical treatment is a kind of method that cures illness or injury using all sorts of factors such as water, electricity, light, and exercises. In general, physical treatment as known to cure the physically tnjuried or the crippled. In this case, taking psychosomatic for example, I examined the idea that many kinds of physical treatments can be used in the field of psychotherapy. What's more, I suggest that the use of those methods be expanded to psychotherapy.

In order to have compressive strength tests and frost heaving tests, two sorts of soil samples at Chonbuk-Do area were used. According to this research, the compressive strength of soil which was mixed by quick lime, was largely increased until 28 days but after 28 days, the increment of strength was seldom found and its maximum compressive strength increasing rate for content of quick lime was $10{\sim}15%$ scope. In the mixed rates of quick lime and briquette ash, the compressive strength of soil which was mixed by quick lime and briquette ash, was increased by increasing mixed rates of quick lime and its compressive strength was increased by additional quantity. The compressive strength of mixed soil within freezing-thawing 1 cycle was diminished around 30% compared to non-freezing soil's 28 days compressive strength but there were no movements after 2 cycle.

The kitchen utensils, a part of dietary life, are tableware and everything needed for cooking, storing foods, arranging and housekeeping. This study has been made on the classification in comparison with utility regarding both the shape and the quality of material. The classifications by the quality of material were ceramicware, woodenware, metalware and stoneware. he classifications by the utility were utensils for cooking, utensils for storing and keeping, utensils for arranging, utensils for grinding and utensils for special use. At the stage of migrating and gathering provisions they needed only simple utensils, but by cultivating, fixing their residence and producing crops they prepared and developed all sorts of kitchen utensils to serve various purposes, social rank, poverty and wealth, season and ceremony.

Magnetic resonance imaging with its superior soft tissue contrast resolution and absence of beam hardening artifacts, combined with its ability to perform multiplanar imaging, is now effective tool in diagnostic imagings. Magnetic resonance is primarily a phenomenon that involves atomic nuclei. It provides totally new clinical informations with no known hazards through the use of very weak interactions with endogenous stable magnetic atomic nuclei. This article briefly summarizes the basic mechanism of generation and detection of the signals and general sorts of tissue properties which can influence the signals and thereby give rise to tissue contrast. It also describes how the machine-operating parameters can be used to manipulate the tissue contrast observed in the image.

In all sorts of primary factor which produce torque ripple of d.c brushless motor cogging torque which is generated from relation between permanent magnet rotor and salient pole cannot controled by external control system. So in this paper cogging torque is analysed by simple method in which slot fuctuion is introduced. And for reducing counterplan of cogging torque d.c brushless motor which plot auxiliary slot by inequality interval is proposed. Thus the quantitative torque characteristics of new motor which designed by this method is analysed by F.E.M and validity of this new design is proved.

In the result of investigating traditional chinese medical literatures to understand definite immun opharmacologic effects of drugs for clearing away heat and detoxicating such as Oldenlandiae Diffusae Herba, Fel Ursi, Fraxini Cortex, Pulsatillae Radix, Bruceae Fructus, Portulacea Herba, Patriniae Radix, we could reach conclusions as follows: 1. Oldenlandiae Diffusae Herba can increase voracity of leukocytes and immune function of splen ocytes. 2. Fel Ursi, Patriniae Radix can inhibit acute, chronic inflammation by decreasing voracity of macrophages, monocytes and recover lymphocytes. 3. Fraxini Cortex have anti-inflammatory effect then applied to treat with arthritis. Pulsatillae Radix, Bruceae Fructus, Portulacea Herba have anti-cancer, anti-biotic effects. Above results indicates that drugs for clearing away heat immunosuppressive effect that they can apply to all sorts of inflammatory diseases such as arthritis, DTH, SLE, and cancer.

This paper discusses about the implementation of a simulator for the Navigation Control System(NCS) of bimodal tram. To operate a NCS of bimodal tram, values of all sorts of sensors installed in bimodal tram should be transmitted to the NCS, and the NCS calculates the measured sensor values to determine traveling direction, traveling speed, current position etc. The implementation of the simulator consists of a device applying driver's input transaction function & virtual sensor program and a sub-rack device that controls communication with the NCS to evaluate navigation control function. The virtual sensor program can create routes (map), traveling profiles & seat information et cetera in order to transmit to the NCS, analyzes driver's input values and NCS output values to create virtual sensor values. The sub-rack device takes charge of communication with the NCS using CAN-OPEN, CAN-J1939, MVP protocols. This paper discusses about the implementation of the simulator and afterwards analyzes and evaluates the NCS simulation results.
