      • 지식의 공유 재이용을 위한 Group ontology에 관한 연구

        장영일 朝鮮大學校 1996 국내석사

        RANK : 247631

        Very Large-scale knowledge based system orients the approach of knowledge sharing and reuse, where a frame of knowledge called common ontology is requested. Many ontology are being build, but each of them is implemented in first-order logic by using knowledge representation language. In such present circumstances of ontology, it occurs the situation such as top-down approach, exclusion of multiplicity and so on, that contradict sharing and reuse approach. This study proposes the concept-map system, the mechanism using visual information, which is a kind of technology, the environment of bottom-up knowledge representation by group. The core of the concept-map system is simplification of logical relations, where human knowledge is supposed to be made from special metaphor. And the concept-map itself allows logical expression described in semantic network. We examined how to specialize the logical expressions and how to manage the specialized knowledge, and did some experiments an that.

        Henri Marie Raymond de Toulouse Lautrec Monfa was born on November 24, 1864, in Albi in south France. The castle came to be called Lautrec Street. He was physically delicate from ' he birth because of his parents' consanguineous marriage , and he was much interested in painting from the time when he was about three years old. Because of his delicate health, he was forced to withdraw from his school and persue his studies with a private tutor, some authorities on him say. In May 1878, he had his thighbone broken, and a year later he fell and badly fractured his another thighbone. We can imagine his appearance with the lower half of the body not having grown there after. Thus he grasped at painting as an escape from his brutally restrained existence. At the age of 18, he found himself in Paris. In 1886, the year his meeting of Van Gogh, he outfitted his own studio in Montmartre where he would stay until 1897. In 1893, at the Goupi1 Gallery he had a show of his works that had been inspired by Montmartre, and it won the approval of Degas. Degas had the greatest influence on his works and he also met the impressionist Manet. While the impressionsts in Paris tried to describe the gorgeousness of the high class. he endeavoured to find out the hidden truth of life through the insight into the dark side of life He didn't followed the impressionistic technics, but he was bold in apace make-up and influenced by Japanese woodcut printings, thus making his line uniquly heavy. His peculiar style shows a mood of decadence of the of a century in urban civilazation and counts as a record in the history of fine art. In this thesis, the fashion of his day having influence on his works, his woodcut printing. and his position in the history of. art Will be discovered.

        우리나라는 급속한 산업발전과 함께 생활수준이 향상됨과 반면에 자연환경 훼손과 무절제한 부존자원의 활용으로 자원의 고갈현상을 초래하고 있으며, 주거지역과 하천 및 연안해역의 오염이 심각하게 되어 생태계 파괴를 일으키게 되었다. 건설 분야에서도 도시개발 시 환경문제의 해결 및 경관의 향상을 위한 노력으로 콘크리트에 잔골재를 사용하지 않고 단입도의 굵은골재를 사용하여 인위적으로 연속공극을 형성시켜 투수성, 투기성, 흡음성, 수질정화 및 식생능력 등의 다기능을 가진 포러스콘크리트에 관심이 주목되고 전 세계는 물론 우리나라도 이에 관한 연구가 점점 증가하고 있는 추세에 있다. 본 연구는 포러스콘크리트의 성능향상을 위해 골재 입도별 탄소섬유와 실리카퓸을 혼입한 포러스콘크리트의 특성을 분석하여 성능향상에 필요한 최적조건을 제안하였다. 또한 골재의 입도와 공극률에 따른 포러스콘크리트를 식생·수질정화용으로 사용하기 위한 현장적용성 평가를 수행하였으며, 그 연구결과를 요약하면 다음과 같다. (1) 실리카퓸을 혼입한 포러스콘크리트는 실리카퓸의 혼입률이 증가함에 따라 공극률은 감소하였고, 압축강도는 동일 설계공극률에서 골재입도 5~13mm의 경우가 13~20mm의 경우 보다 4.8%~8.8%만큼 더 큰 강도가 발현되었다. 동일 입도에서는 실리카퓸을 10% 혼입한 경우가 가장 양호한 강도특성을 발현하였다. (2) 탄소섬유를 혼입한 포러스콘크리트는 탄소섬유의 혼입률이 증가함에 따라 공극률은 감소하였고, 탄소섬유를 3% 혼입한 경우가 가장 양호한 강도특성을 발현하였다. 또한 실리카퓸 10%와 탄소섬유 3%를 혼입한 포러스콘크리트는 보통포러스콘크리트 보다 1.6배의 등가휨강도를 발현하여 변형성능이 현저히 개선됨을 확인하였다. (3) 포러스콘크리트에 Setaria Viridis를 식재하여 식생능력을 평가한 결과, 파종 후 30일까지는 객토층에 존재하는 양분과 수분을 공급받아 양호한 생육상태를 나타내었으나, 파종 후 60일 후부터는 골재입도와 공극률이 작을수록 생육상태는 부진하였다. 따라서 포러스콘크리트의 식생능력은 골재입도에 의한 영향을 가장 크게 받으며 동일한 골재입도에서는 공극률에 영향을 받는다고 판단된다. (4) 포러스콘크리트를 하천에 침지시켜 미생물을 부착시킨 후 실내수질정화수로에서 수질정화 능력을 평가한 결과, 포러스콘크리트는 골재입도가 작을수록 또한 동일한 골재입도에서는 설계공극률이 클수록 인과 질소의 제거능력이 향상되었다. 따라서 포러스콘크리트의 수질정화 능력은 연속공극으로 형성된 비표면적의 크기에 큰 영향을 받는다고 판단된다. Industrialization has made Korea enjoy abundance in living, but in contrast, the destruction of the environment and uncontrolled exploitation of natural resources has exhausted resources with economics considerations replacing environmental ones. Inconseq uence to this development, the developed areas have been seriously contaminated destructing the eco-system in those areas. At the United Nations Conference on the Environment and Development, it was advocated that the combination of* A thesis submitted to the committee of the Graduate School, Chungnam National University in partial fulfillment of the requirements for the degree of Master of Engineering Conferred in February, 2005 environmental concerns together with development is more desirable than mere conservation. Consequently, in the construction sector, development is being made considering both environmental problems and improving scenic beauty of cities. The harmony between nature and concrete structures was also required. In view of this requirement, various research paths are being taken focusing on coarse aggregates to make multi-functional porous concrete having continuous voids so as to improve water and air permeability, acoustic absorption, water purification, and applicability to vegetation In this study, According to physical and mechanical properties of porous concrete using silica fume and carbon fiber were analyzed, the optimum condition that was needed to improvement in performance was proposed. Also, field application test was put in effect of using porous concrete for water purification and planting. The result of the study are as follows : (1) When the ratio of silica fume increased, the void ratio of porous concrete using silica fume decreased. the porous concrete containing 5mm to 13mm aggregate exhibited 4.8% to 8.8% greater equivalent strength than the porous concrete containing 13mm to 20mm aggregate. Porous concrete using the silica fume of 10% also has a excellent compressive strength when the target void ratio is identical. (2) When the ratio carbon fiber increased, the void ratio of porous concrete using carbon fiber decreased. and porous concrete using the carbon fiber of 3% has a excellent compressive strength when the target void ratio is identical. it also has a excellent strength when the silica fume mixing ratio was 10% and the carbon fiber mixing ratio was 3%. The porous concrete exhibited 1.6 times greater equivalent flexural strength than the general porous concrete when the silica fume mixing ratio was 10% and the carbon fiber mixing ratio was 3%. So we can confirm an improvement of porous concrete ability. (3) The planting ability of porous concrete is evaluated by the germination and Setaria Viridis. They grow up each other for 30 days similarly, because there is to improve the soil layer that has nutrient and moisture on the porous concrete. Growth had been decreased when the gradation of aggregate and void ratio were smaller after 60 days. Also, it have decreased in 5mm to 13mm aggregate. So the planting ability was gradation of aggregate especially. And when gradation of aggregate is identical, it was influenced by void ratio. (4) After porous concrete was immersed under water, and attach a microorganisms to it. The result of evaluation water purification ability at indoor water purifying channel, the porous concrete spend dissolved oxygen when gradation of aggregate was smaller. And when aggregate size is identical, the dissolved oxygen consumption increased in proportion to the target void ratio. The T-P and T-N removal capacity of the porous concrete containing 5mm to 13mm aggregate was higher removal capacity than in case of the porous concrete containing 13mm to 20mm aggregate. When aggregate size is identical, the quantity of removal increased in proportion to target void ratio, also the removal quantity of T-P and T-N were influenced by specific surface area and continuous void.

        Wireless Sensor Network(WSN) is researched in various filed. Underwater Sensor Network(UW-SN) is used various purpose such as underwater environment monitoring. But, WSN is researched in the terrestrial that uses mainly radio frequency, The existing terrestrial research is incongruent to apply to underwater. Therefore, we propose UW-SN architecture that considers underwater environment. In this paper, UW-SN applied cluster technique and functional node constructs. Each cluster collects and sends cluster data. Dual super cluster head receives cluster data and transmits each in the base-station. We implement UW-SN routing algorithm, and construct test-bed and analyze cluster data receive rate.

        Background: Sensitization increase responsiveness and reduce threshold of nociceptors to stimulation of their receptive field. The symptom of sensitization occurs in many disease related with nervous system or musculoskeletal system. Sensitization has two characteristics which are allodynia and hyperalgesia. Sensory and motor signals are connected and affect each other. Also, noxious sensory input “pain” affects the movement system. However, there are lack of studies investigating effects of pain induced sensitization to motor control. This study investigates the effects of sensitization induced pain on C8 dermatome on maximal voluntary force (MVF), finger enslaving (FE) and finger sharing (FS) in the maximal finger pressing tasks. Methods: Sixteen healthy right-handed young adults (eleven males and five females) performed MVF task during three days. In first day, all participants performed experimental protocol. In either second or third day, participants were divided into two groups randomly to determine the day of inducing sensitization by capsaicin on C8 dermatome of medial forearm and performed MVF task with same protocol. Before and after administering capsaicin, 42°C heat was applied for 10 minutes and 5 minutes respectively. The intensity of pain was measured by visual analog scale and von frey filaments were used to confirm sensitization in medial forearm and finger. Results: Results of this study showed that after sensitization, MVF of middle finger and all four fingers decreased significantly (p<0.05). However, FE and FS both did not show significantly difference on all fingers. Conclusion: Pain derived from sensitization of the C8 dermatome affected the finger flexor muscles together but did not affect individual finger muscles. Clinicians need to understand the characteristics of pain derived from sensitization and know the best methods of rehabilitation for patients.
