Parents play a very important role in propagating and utilizing of the traditional games for children, because the maximization of educational effect can be achieved when the traditional games are utilized in connection of infant education systems and homes. This study aimed at an inquiring of the parents' cognition and application about the Traditional Games for Children for the education connected with infant education systems and homes. This study was conducted by questionnaire which was answered by parents. The question papers were analyzed through SPSS 10.0 for Windows. The results of this research are as below. Af first, the results of the research about the parents' cognition and application about the Traditional Games for Children are as below. First, concerning the degree of interests and acknowledgements about the Traditional Games for Children, Parents regard the concept of the Traditional Games for Children as games which were passed on from ancient times and almost of them have interests of the Traditional Games for Children. Second, concerning the interests of the Traditional Games for Children in infant education systems, parents understand that traditional tales are most directed but the experiences of cultural remains are lacked. Third, most parents admit the necessity of the Traditional Games for Children because they think the Traditional Games for Children include our own traditional consciousness It indicates that parents are very interested in our own traditions. Fourth, concerning the interests of participating programs related with the Traditional Games for Children, 70% of answers admitted the necessity of them, and 60% of answers had experiences of participation programs. It means that infant education systems must give parents many chances of participating in the Traditional Games for Children and learning them. Secondly, the results of the research about the parents' application about the Traditional Games for Children are as below. First, concerning the kinds of the Traditional Games for Children which parents experience, Towel Turning Game(84.4%) is the highest, and Site Taking Game and Rubber Line Game are also high. They are the games which are enjoyed much today. Secondly, the kinds of the Traditional Games for Children which parents apply with their children, Hide-and-Seek is the highest in 72tradition games and the games answered above 50% are only 10 kinds. The interests of parents about the Traditional Games for Children are very high. Furthermore they not only think them very positively but also have very active intention of practical use of them. Therefore, the necessities of activating the Traditional Games for Children are verified through my research. Finally, 1 suggest that some programs connecting infant education systems and homes must be studied along with the parents' active interests and intention of practical use of the aditional Games for Children.

The present experiments were designed to investigate the effects of Ondamtang water extract(Ondamtang) on the blood circulation, bile acid secretion and mental tension in normal and hyperlipidemia induced rabbits. In order to control the precise chemical and physical conditions, the experimental rabbits were supplied with calorie limited food, and the hyperlipidemia rabbits were induced by oral administration of cholesterol(500㎎/㎏) for 3 weeks. The results obtained were summerized as follows: 1. Ondamtang increased the bile secretion and serum bile acid level in rabbits. 2. Bile solution decreased the blood pressure after injection through the ear vien in rabbits. 3. The blood pressure was decreased after injecting Ondamtang through the ear vein. And it was also decreased after oral administration of Ondamtang for 5 days. 4. The decrease of blood pressure was not dependant on the autonomic nervous system. 5. Ondamtang activated the Mg^2+ -Ca^2+ -ATPase activity of cardiac indoplasmic reticulum, and thus inhibited the cardiac muscle contraction. 6. Ondamtang stimulated the dilatation of the peripheral blood vessel. 7. Ondamtang decreased the serum creatinine level by stimulating the renal filtration and thus it increased the kidney function in hypelipidemia rabbits. 8. Ondamtang decreased the arteriosclerosis index by effecting the metabolism of cholesterol and lipid in hypdrlipidemia induced rabbits. 9. Ondamtang inhibited the Na^+ -K^+ -ATPase activity of the cerebral cortex, and decreased the sensitivity of the electrical shock. According to the above results, Ondamtang improved blood circulation by dilatation the capillary lumen and decreasing in blood viscosity, promoted bile acid secretion, inhibited the nerve transmission, and relieved the mental tension.

. The effect of concentrations of urea and melamin resin solutions on the impregnation, thermosetting, and physical properties of the preformed gypsum body was studied to improve the mechanical strength and water resistivity of the substrate material. A maximum impregnation was obtained when the urea and melamin resin concentrations were 60% and 50%, or the viscosities were 100 cp and 200 cp, respectively. High mechanical strength of the resin impregnated gypsum was observed in this range of concentrations. The amount of residual free water in a heat-treated gypsum was found to be increasing and the mechanical strength, consequently, was found to be lowered with decreasing the resin concentration. Since the resin was considered to be absorbed only on the surface of the substrate material, water resistivity of the composite was found to be increasing up to three times of that of a hydrated gypsum, say 3 to 5%, as the concentration of the resin solution increased up to 60%.

顫振(tremor)은 頭部나 四肢가 부자유스럽게 흔들리거나 혹은 떨면시 움직이는 疵狀을 말하는 것으로 顫振의 節時에는 頭搖,手顫, 足顫,身振搖,舌顫, ㅁ顫 等이 포함된다.顫振에 대한 文??的 考察을 통해 顫振을 部位 와 관계없이 全體的인 觀點에서 病因別로 分類할 수 있었고,顫振이 發顯되는 部位에 따라 分類하여 名名의 病因別로 分類할 수 있었다. 이 두가지의 分類틀 통해 相互 連繫性을 찾아 顫振의 治療에 도움이 되고자 顫振의 病因 및 治方을 調査하여 考察하였다. 考察한 結果 顫振의 治療는 共通的인 病因에 使用된 治方을 基本方으로 하고,顫振의 發顯部位에 따라 名名 特徵的으로 使用된 治方을 參照하여 應用해야 할 것으로 思料된다. Tremor is defined as involuntary motion of the head,limbs,and other parts of the body. Tremor is due to the general mechanism,so called "Malnutrition of Tendon (筋失濡養)",but various subtypes due to etiology exists. The disease is dassified in the view of the lesion and its pathogenesis. According to the lesion,it could be classified to tremor of head(頭搖),tremor of hand(手顫),tremor of foot(足顫),tremor of the whole body or truck (身振搖),tremor of toung(舌顫),tremor of lip(脣顫),etc. These subcategories are caused by exopathic wind (外感風邪),hyperactivity of the liver - yang (肝陽亢盛),up - stirring of liver (肝風內動),deficiency of both qi and blood(氣血虛弱),exuberance of the liver - wind (肝風盛),insufficency of the heart - fire (心火不足),insufficency of the heart - qi (心氣虛),failure of heart (心絶),deficiency of blood (血虛),wind - cold - dampness (風塞濕),deficiency of both qi and blood (氣血虛弱). blood depletion due to hypofunction of the spleen (脾虛血燥),deficiency of blood in the heart and spleen (心脾血虛). Out of these pathologic mechanisms,the former four conditions are the most common factors of the disease. And general drugs used to control the four common factors are Lingjiao Gouteng Tang (羚羊鉤藤湯),Tianma Gouteng Yin (天靡鉤藤欲),Renshen Yangying Tang (人蔘養榮湯),Bazhen Tang (八珍湯), Da Dingfeng Zhu (大定風珠),Da Buyin Wan (大補除丸),Daotan Tang (導痰湯),Cuigan Wan (崔肝丸) etc. In addition,there are specific factors and drugs to each lesion. To sum up,tremor of head(頭搖),tremor of hand(手顫), tremor of foot(足顫),tremor of the whole body or truck (身振搖),tremor of toung(舌顫),tremor of lip(脣顫) is resulted from up - stirring of liver (肝風內勤),insufficency of the heart - qi (氣血虛弱),wind - cold - dampness (風寒濕),deficiency of blood in the heart and spleen (心脾血虛),blood depletion due to hypofunction of the spleen (脾虛血燥),and the fire of Stomach Channel (胃經之火) respectively. Each symptoms treated by Lingjiao Gouteng Tang (羚羊鉤藤湯),Reinforcing the heart Wan (補心丸),Wuji San (五穰散),Guipi Tang (蹄脾湯),Shuangjie Tong sheng Shan (雙解通聖散),Siwu Shufeng Tang (四物疎風湯). (The last two elements are induded to the 脣顫) On the basis of this study, we can use basic drugs which is treat the common factor, additionally add specific medication as to the lesions. In this method, we can approach the disease effectively, and try more comprehensive solutions include etiology, pathology, and pharmacology.

High silicon Al-Si alloys with nanocrystalline structures have been produced by mechanical alloying process. Microstructural changes of the Al-Si alloys were investigated by scanning electron microscopy and the transmission electron microscopy. X-ray diffraction analysis was also made to characterize the lattice constant, crystallite size and misfit strain. It was found that the effective milling time by attrition milling was about 12hours for Al-70 wt%Si alloy system. The Al and Si crystallites were reduced to about 30 nm and 70 nm, respectively, by the mechanical alloying for more than 12hours. The misfit strains increased with milling time UD to 240 hours, and saturated to 5.73×10^(-3) for Al and Si crystallites, respectively.
