Hepatocellular carcinoma frequently metastasizes through direct extension, lymphatic, and hematogenous routes. The most common sites of metastasis are the lungs and the lymph nodes, glands, bones, spleen, kidneys, colon, and pleura are the sites of metastasis in decreasing order of frequency. But metastasis to the ovary is very rare. It is thought that metastasize to the ovary occurs through infiltration or dissemination. However, we observed ovarian metastasis of primary hepatic tumor in a 34-year old female who suffered from lower abdominal pain. At first, it was diagnosed as a primary ovarian tumor. But histologically, it presented sinusoidal pattern surrounded by the tumor cells and contained rounded by the tumor cells and contained round hyaline globules in minority of the cytoplasm. Then, the histologic features of percutaneous, sono-guided liver biopsy speecimen of the liver mass are similar to those of resected ovarian tissues. Therefore, we concluded that ovarian tumor was originated from hepatocellular carcinoma. In summary, this report examines a case of hepatocellular carcinoma with ovarian metastasis in a female and reviews the literature.

Skin-layer insert molding has a lot of merits. This reduces a process number and production costs, and improve an environmental problem as do not use a bond. However, a technology is still short. The following things shalI be equipped so that insert molding succeeds. A lot of information regarding a preferential skin-layer is necessary. And The injection machine that minuteness control is possible is necessary. Support analysis for technology development in this study. also Injcetion-compression molding certailny needs this researcher in order to be achieved.

The purpose of this thesis was to investigate plato's view of body and soul from the core of his philosophy Idea, and its influences of his physical thoughts. Some important points of plato's physical thoughts were as follows. 1. In contrast to the general concept that Plato was the mere philosopher of metaphysical dualism an regarded the body as inferior to the soul, he compared the baby to thing and the soul to Idea, and suggested an inseparable relations between body and soul. 2. Plato emphasized physical education to achieve his " Ideal state" in which the great citizens and rulers could be brought up. 3. Plato insisted that physical education should go along mental education of the perfect character building and for the first time promoted firmly the position of that to one of two maintenance in the history of the world physical education. 4. On the basis of ideological thought of physical thoughts, Plato regarded physical education as essential in order to bring up the whole man who was harmonized and balanced with in his mind and body. 5. Plato explained physical education in detail from nursing period, infant period, juvenile period to the youth period. 6. Plato regarded the proper ingestim of nutrition along with the exercise as the principle of physical education. 7. Plato demanded to build three Gymnasiums respectively in the city and in the suburbs. cavalry school and even the teacher's houses. And he insisted that the facilities should be always opened for the enough use. In case it could not be fulfilled, he suggested lawful settlements. 8. In the general rules of personnel administration, Plato discoursed on the duty, qualification and organization.

The purpose of this study was to find out if the mental practice for a certain period will influenced the record improvement of ball-throwing or not. We randomly picked out forty boy student subjects who were in the third grade in middle school. We divided the subjects into five groups-the first group (only mental practice), the second (physical practice after mental practice). the third (mental practice after physical one), the fourth(only mental practice), and the fifth (non practice)-and had each group try the practice three time, every week for eight weeks. through the close comparison and analysis over the records measured before and after the practice, we came to a conclusion like this : 1. Only mental Practice isn't effective. 2. Physical practice, physical after mental practice, mental practice after physical one, and all influence the record improvement of ball-throwing. 3. There is no any meaningful difference among physical practice, mental practice after physical one, and physical practice after mental one with each other. 4. Mental practice has no effect on the record improvement of ball-throwing.

In this study, 24 curved resin blocks were prepared by one of the following four methods: 1) Conventional technique using K-flexo files 2) Step-back technique using K-flexo files 3) Crown-down technique using K-flexo files 4) Canal Master instrumentation using Canal Master Resin blocks were sectioned, photographed, and evaluated the mean centering ratio and the mean area of dentin removed before and after the instrumentation. The results were as follows: 1) the mean centering ratio 1. In the level 1 and level 3, there was no significant difference in the mean centering ratio. 2. In the level 2, Step-back technique showed the worst mean centering ratio among the tested groups ( p<0.001 ) and there was no significant difference between the other three groups. 3. In the level 4, Canal Master instrumentation and Step-back technique showed better mean centering ratio than the other two techniques ( p<0.001 ) and there was no significant difference between the two techniques. 2) the mean area of dentin removed 1. In the level 1 and level 3, there was no significant difference in the mean area of dentin removed. 3. In the level 2, Canal Master instrumentation removed less dentin than the other three techniques ( P<0.01 ). 4. In the level 4, Crown-down technique removed less dentin than the other three techniques ( P<0.05).

The Mo¨ssbauer effect studies of the quenched glass and heat-treated glasses were performed. The Debye and Einstien temperatures of the quenched glass, determined using the center shift and kinetic temperature, are 540K and 430K respectively. The X-ray diffraction pattern showed that the heat-treated glasses were crystallized. Form the isomer shift of the heat-treated glasses, it was concluded that the Fe^(3+) ion is predominantly octahedrally coordinated.

Electron spin resonance studies of the radical DMPO-OH induced by Fenton reaction have been carried out at room temperature. The ESR spectra have 4 hyperfine lines due to interactions with the nuclei of nitrogen and hydrogen at the position of βin the radical DMPO-OH. As results of our analysis, the ESR parameters have been found that ?? , the hyperfine coupling constants are well accord with those of Chamulitrat et al. and Akira Hamata but ?? that is reported on this paper.

To make high speed spindle system work properly, sensors with outstanding resolution and dynamic characteristics are essential. An optical fiber displacement sensor is based on simple principles. Electrical signal responds to the optical flux change due to the displacement change between a target and a sensor probe. In this paper, the performance of optical fiber displacement sensor has been investigated according to properties of optical fiber. Firstly, optical loss has been measured before and after polishing optical fiber endface. Secondly, allowance of optical fiber bending has been tested. thirdly sensitivity and linear range of the sensor has been found out according to the shape of cross section of optical fiber.
