In this research, We connect the terrestrial magnetism sensor of the Philips to a bluetooth communication system and measured 360 degree of the azimuth change the angle with an incline of 5 degrees to an order direction. The value of the azimuth to be measured sent to the Bluetooth communication system and analyzed the measuring value in the 100m as moved. Using the bluetooth, we could send the measuring value of the azimuth without the bearing error in the plain without an electric wave obstacle within a distance in straight line 100M. We got the value of the azimuth have 98% reliability to maintain at a level with the terrestrial magnetism sensor. Based on this research. We send the measuring value of the azimuth which the accuracy is improved to a mobile intelligent robot moving a land inclined equipped with this system and can track the azimuth of it. 본 논문에서는 필립스사의 지자기센서를 블루투스 통신시스템에 연결하여 방위각을 $5^{\circ}$ 단위로 전후 방향으로 기울기 각도를 변화시켜 $360^{\circ}$를 측정하였다. 측정된 방위값은 100M 이내에서 이동하면서 측정값을 블루투스 통신시스템으로 전송하여 측정값을 분석하였다. 블루투스를 이용하여 전파 장애가 없는 평지에서 직선거리 100M 이내에서 방위 측정값은 에러 없이 전송할 수 있었다. 지자기센서를 수평을 유지하면 98%의 신뢰를 가지는 방위측정값을 얻었다. 본 연구를 바탕으로 기울기를 가지는 지형을 이동하는 이동형 지능로봇에 장착 정확도가 향상된 방위 측정값을 전송하여 이동형 로봇의 방위추적을 할 수 있다.

Biliary cystadenomas are rare cystic neoplasms of the biliary ductal system. Cystadenomas have a tendency to recur, particularly following their incomplete excision, with the potential for malignant transformation. Cystadenocarcinomas are very rare and; despite complete resection, can recur in a short time. A cystadenoma cannot be easily differentiated from a cystadenocarcinoma preoperatively or intraoperatively; therefore, complete surgical resection should be always considered. Four biliary cystadenoma and one biliary cystadenocarcinoma cases, treated at the Kyung Hee Medical Center, between 1998 and 2003, are reported. The patients were comprised of one man and four women, with a mean age of 45 years. Four patients presented with abdominal pain or jaundice, and the other was asymptomatic, with an incidentally discovered liver tumor. Preoperative CT scans demonstrated a multilocular cyst in four patients and a choledochal cyst-like appearance in the other. All patients underwent complete excision. One cystadenoma arose in the extrahepatic bile duct and the other four appeared in the liver. A histological examination revealed a mesenchymal stroma, which resembling ovary, in two cystadenomas. None of the four patients with a cystadenoma developed a recurrence. However, the patient with a cystadenocarcinoma underwent two pulmonary wedge resections for pulmonary metastases 14 and 21 months after the liver resection.

레오니트 안드레예프(Л.Н. Андреев)의 창작에 나타난 초인 형상 연구: 『생각(Мысль)』을 중심으로

Leonid Andreyev is one of the writers on whom Nietzsche exerted serious impact. Andreyev was hugely inspired with an idea of the superperson. A thin border between the good and evil which was fed by the specific demonic power of human thought and which with little effort can be destroyed was noted by him. The first attempt of Andreyev to embody an image of the superperson in the creativity was made in the story Story about Sergey Petrovich. In this story the hero wants to become the immortal free person through a suicide. In 1906 Andreyev publishes the story Savva. The main character of the story Savva believes that dishonourable people got rid of God and replaced it with hundreds of idols. The image of the superperson created by Andreyev gains development in the story My Notes (1908). The thought, destructive by the nature, creeps in the head of the main character imprisoned in a solitary confinement. The power peculiar to this thought is an essence of this story. The concept of power of thought is borrowed from the story Thought (1902). The image of the superperson was developed further in a number of Andreyev`s works. This image gained more distinct features in the play Thought of the same name. The main character of the play Kerzhentsev wants to replace the morals and an order established by God. Thereby the hero seeks to become a superperson by means of his own thought. However this attempt fails as his own thought betrays him. Andreyev`s heroes wish to become a superperson to step over the line between of the good and evil established by God, but all their plans are destroyed. They wanted to destroy God`s order, but as a result they destroy only themselves. In a word, Andreyev`s superperson is not the one who proclaims that God died, but the one who proves with all his being that it is impossible to resist God`s purposeful plan.

I embodied circle type 3-DOF 6 legged robot in order to install servomotor to maximum 24 in a process. 18 servomotor are used in joints for walk, and 6 servomotor was made so that you can use it in work achievement as robot later. Walking comparison is carried out for the experiment of horizontal type 2 line 2-DOF 6 legged robot in order to test efficiency of embodiment circle. According to testing result, circle type 3-DOF 6 legged robot could do average walking time with horizontal 2 line 6 legged robot as forward walking. Its 360° turning abilitys at place is two times faster than other robot in average walking time. It walked average 5sec faster than other robot in the target turning test and 45° sharp curve. Its center change was ±5mm stabler than other in horizontal walking type 3-DOF 6 legged robot. This showed that it can reduce robot s sensor error and has capability to work a chievement as horizontal migration. A load test shows possibility as work robot afterward because it walked straight in the central axis with 2.5kg load such as circle 3-DOF 6 legged robot. According to the result of experiment, circle 3-DOF 6 legged robot has more advantage as demand a lot of rotations or walk in a rapid radius of rotation.

Intraductal papillary mucinous neoplasms of the bile ducts (IPMNs-B) are uncommon lesions that are characterized by innumerable papillary fronds that contain fine vascular cores, enriched mucin production and bile duct dilatation. IPMNs-B are histologically similar to intraductal papillary mucinous neoplasms of the pancreas and they are occasionally associated with hepatolithiasis. IPMNs-B are considered to be relatively low- grade malignancy and they merit consideration for aggressive surgery. Thus, early and precise diagnosis is important to maximize patient survival. From July 2002 to March 2006, we identified four patients with IPMNs-B at our hospital. In three patients, intrahepatic or extrahepatic bile duct stones were associated with their condition. Computed tomography and magnetic resonance cholangiography were done in all four cases and this demonstrated marked dilatation of the biliary tree. Endoscopic retrograde cholangiography was done in two cases and a large amount of mucin that was draining from the patulous orifice of the duodenal papilla was seen on endoscopy. However, two cases were initially misdiagnosed as intrahepatic cholangiocarcinoma or choledochal cyst with intrahepatic bile duct stones. All the cases underwent ipsilateral hemihepatectomy with caudate lobectomy. Histologically, one case showed to be adenoma, one case was borderline and two cases were invasive adenocarcinoma.

Sweet potato powders made from eight Korean varieties, including purple-fleshed, orange-fleshed, and commercial dry type sweet potatoes, were investigated for physicochemical and pasting properties to develop processed food. Crude protein and lipid contents of Shinjami and Borami were higher than those of other varieties. The lightness value of raw sweet potato flesh was the highest value in Shinchunmi, and the lowest in Shinjami. Using the color difference (ΔE), color similarities compared to the white plate occurred in the following order; purple-fleshed>orange-fleshed>commercial dry type sweet potatoes. Total and damaged starch contents were significantly different (p<0.05). Total starch content of sweet potatoes was higher in commercial dry sweet potatoes (61.89-70.46%), particularly Shinchunmi (70.46%) but lower in orange-fleshed sweet potato (48.87 and 49.53%, respectively). Water binding capacity of Yeonwhangmi, swelling power and solubility of Shinyulmi were the highest values (174.70, 25.54 and 87.49%, respectively) among them (p<0.05). But oil absorptions of Shinyulmi and Shinchunmi showed lower values (97.08 and 97.54%, respectively). All sweet potato powders had an A type x-ray diffraction pattern. the initial pasting temperatures of sweet potato powders ranged from 69.50 to 75.95˚C and the amylolytic enzyme in sweet potato powder lowered pasting viscosity.

This study examined physicochemical properties of rice grains and qualities of cooked white rice of the high yielding, Japonica type, specifically Druryechanbyeo and Boramchanbyeo, and of the Tongil-type, specifically Hanarumbyeo and Andabyeo. The changes of water absorption rate of rice grains, their textural properties and a sensory evaluation of the cooked rice s were analyzed. All varieties were short grain. The length and width of Tongil type rice grains larger than those of Japonica type. The water absorption of white rice grains increased rapidly until 1 hr when soaking and after that increased slightly. The water absorption of Druryechan grain was higher than that of the Boramchan. The sensory evaluation results showed that the Japonica type cooked rices had a higher value for overall quality than the Tongil type cooked rices. With regard to the textural properties of the cooked rices, the hardness of Boramchan and Hanarum varieties showed higher than that of Druyechan and Anda varieties. Adhesiveness, springiness and chewiness were not significantly different between varieties (p<0.05).
