Through investigating the effects that result from the form and preference of Ahnsan (案山) and Jusan(主山) symbolizing ground in the cases of 21 of the Korean Academics for classical learning which called Seowon(書院) located in South Korea of the whole 47, to layout the Korean Academics for classical learning, what factor Sarim(士林) preferred to and how they analyzed the form of circumjacent mountains by Fengshui. While the Jusan has intrinsic attribute due to connecting with the place, Hyuljang(穴場), the Ahnsan has public and extrovert. It can be explained that the Sarim who established the Korean Academics for classical learning had their internal hope and external justification. To put it concretely, because of their necessity of concentrating on their study within nature and their situation as hermits apart from government through long time, they made the Korean Academics for classical learning stable and satisfactory. Therefore, they had to choose Moogocksung(武曲星) as a Jusan. And their study was essential method to take their justification. And It was attractive for them to be a public officer by their study. So they preferred to Moonpilbong(文筆峯) symbolizing their achievements on their study. So the layout of the Korean Academics for classical learning tells us that the Sarim sought internal stability and external scholarship.

A fuzzy logic for collision avoiding navigation of marine vehicles is proposed in this paper. VFF(Virtual Force Field) method, which is used widely in the field of mobile robots, is modifiel to apply to marine vehicles. The method is named MVFF (Modified Virtual Force Field) mothod. The MVFF consists of the determination of the heading angles far track-keeping mode ($\psi_{ca}$)and collision avoidance mode ($\psi_{ca}$). The operator can choose the pattern of the track-keeping mode in the proposed algorithm. The collision avoidance algorithm can handle static and/or moving obstacles. These functons are implemented using fuzzy logic. Various simulation results verify the proposed alogorithm.

Confucian doctors (儒醫) emerged who either voluntarily or involuntarily studied medical science and participated in clinical practices. This was made possible by a newly established position known as Euiseoseupdokgwan (醫書習讀官), made up of officials who had knowledgeable about medical books, during the reign of King Sejong. By the 16th century, Confucian doctors who acquired knowledge from medical books began to practice more broadly. Most of the Confucian doctors had either direct or indirect connections with the Sarim faction 士林派, and had interest in practicing medicine in provincial regions. In 1610, Donguibogam (東醫寶鑑) was published, providing the Confucian doctors with solid academic and clinical foundations. From the late 17th century onwards, the medical environment quickly became commercialized and the status of Confucian doctors gradually weakened.

This study looked into the process by which Haseo(河西) Kim In-hoo(金麟厚:1510~1560), a neo-confucian scholar of mid Joseon Dynasty, was recognized and adored as an inheritor of traditional academic genealogy of neo-confucianism of Joseon Dynasty. I intended to examine the process of personal embodiment affected or excluded in certain manners by various materials covering the lifetime of bygone persons based on the process of such embodiment. The part related to childhood of Haseo was arranged newly to highlight solid relationship between Kim In-hoo and King Injong(仁宗). That was because Kim In-hoo raised the issue of loyalty and fidelity, one of the most important and most contentious issues at that time, in connection with reinstatement of GimyoSarim(己卯士林, progressive political faction with young officials), and King Injong was the king who reinstated Gimyo Sarim. That played a decisive role in establishing the image of Haseo, a classical scholar with unwavering integrity and loyalty. During the Late Joseon Dynasty, canonization of Haseo was made under the leadership of King Jeongjo(正祖) and Seoin(西人) in royal court. In the 17th century, Seoin scholars revised the materials related to lifetime of Kim In-hoo in various way and proofread and published the collection of literary works by Kim In-hoo. That aimed to establish scholastic system associated with Seoin and legitimacy of study as pursued by Seoin. This made progress with adoration towards scholars affiliated with Seoin, including Yulgok(栗谷) Lee Yi(李珥). Finally, King Jeongjo showed strong intention to take the lead as sovereign in the process while Haseo was canonized into national academy in the 18th century. That came from the desire to solidify his status as a teacher who took pride in taking responsibility for the dynasty's authentic study, as well as the king heading the dynasty politically.

There are many problems in wire fabrication of long length Bi-2223 superconductor by using conventional extrusion method. They are mainly due to high surface resistance and inhomogeneous distribution of inner stress. Hydrostatic extrusion process will not only decrease the extrusion pressure but also enhance homogeneous deformation of material by reducing friction force between billet and container Hydrostatic extrusion method is considered to be useful fur fabrication of the homogeneous wire with high density. In this paper, hydrostatic extrusion process is introduced to fabricate Bi-2223 superconducting tape, and also discussed are the interface homogeneity and microstructural aspects of extruded BSCCO/Ag billet.

The Honam region has played an important role in the development of Korea poetry. So this study focuses on Song Soon among various factors of Honam architecture in 16th century. He was ahead of his times in development of Korean literature, and made buildings that become background and materials of his literature. Song Soon built Myonang-jong in Damyang for his life time and tried to design to pull in nature into his buildings. These buildings were built in beautiful landscape, and showed elegance as a retired scholar and Taoism characteristics. He provided basic ideas, that is, pulling in nature into architecture, and metaphysics morality, and his ideas also influenced Honam School Including Jung Chul. This study looks into Nujung architecture that had become materials of Myonang-jong Song Soon literature and characteristics of Honam architecture through his buildings at the same time.

Seowon(書院) is a representing institution in Choseon Dynasty not only educationally but also politically and economically. Due to the artificial crackdown by Daewon-gun in 1871 and destruction by wars, it is difficult to restore and interpret the Seowon accurately at present. It is well known that the 'Basic Form' of the Seowon consists of an inner court, enclosed by the rear gangdang (lecture hall), dongseo-jae (east and west dormitory), and the front munlu (gate pavilion or upper story bower for relaxation), represented by so called 'front-dormitory rear-lecture-hall type', that is, 'jeonjae hudang(前齋後堂) type'. However, it is overlooked that this Basic Form is a product of Youngnam School located only in Youngnam area. A different form, of 'front-lecture-hall rear-dormitory type', or 'jeonndang hujae(前堂後齋) type' is located only in Gyeonggi, Hoseo and Honam area. It has been wrongly analyzed that the type is a result of the later period, emphasizing the memorial service rather than the lecture itself, and worshipping loyalists than Confucian scholars. Analysis encompassing each Seowon architecture has been mistakenly made by historians as "deterioration" of the original educational purpose of the Seowon from the early period to the later period. This paper raises the fact that the form of jeondang hujae type has been established since the early period of Seowon in the 16th Century. It has a unique order of space itself. Here, the lecture hall faces toward sadang (shrine). The inner court, enclosed by east and west jae and the lecture hall, becomes the outer yard of the shrine, and as a result two main spaces of the shrine and lecture area is merged into one. While the munlu of the basic type encloses the inner court of the main area, the munlu of jeondang hujae type is located at the vicinity area. This paper reinterprets the jeondang hujae type not as a form coming out of degenerated period but as a type that belongs to a different Confucian school, the area of Kiho, and concludes that the Seowon is a product of political struggles between the two schools and of the local economical situation. Each school has maintained his own type of form, therefore the remaining Kiho Seowon architecture can be reevaluated.

Hanhweon-dang Kim Goeng-pil(1454~1504) sublimated ethics whose lead was opened up by Jeong Mong-ju in late Goryeo as one scholarly tendency. Kim Goeng-pil was called 'the father of ethics in Joseon' and has been respected as a model of ethicist for 400 years since then. Following Kim Goeng-pil, Confucian scholars of Joseon cultivated perseverance through Xiaoxue and the perseverance was sublimated to Confucian scholars' energy and then that of state, which served as driving force to keep the national legacy. Kim Goeng-pil suggested how to study with Xiaoxue and sought moral human beings and ethically ideal societies based on strong practicability which is required in Xiaoxue. Individuals' cultivation and social reform are not at a different dimension. Spirit of 'self-cultivation' that Kim Goeng-pil himself demonstrated advanced to pursuit of ethical, ideal state when reaching a level of Jo Kwang-jo. Kim Goeng-pil thought that teaching in Xiaoxue could be achieved through 'Gyeong (敬, respect).' It is the key of Neo-Confucianism in Joseon to control one's mind through the cultivating method of 'Gyeong.' Kim Goeng-pil settled Joseon's Confucianism as 'practical ethics(心學).' Before Kim Goeng-pil, no scholars had well presented the aspects of practical ethics. After King Myeongjong and Seonjo, Confucianism in Joseon worked as the cornerstone of practical ethics. Since mid-17th century, the system of practical ethics had been firmly established with focus on 'Gyeong. Literary men of Kim Goeng-pil and scholars they fostered led the academic and political world of Joseon after mid-16th century. They played the lead in Sarim faction's(士林派) ruling after King Seonjo came to throne. The very foundation which sublimated Joseon to the ethically ideal state and made the Dynasty a 'state of Sarim' was actually laid by Kim Goeng-pil.

Sewon was a new type of private academy established by a class landed Confucian scholars known as sarim. During Joseon dynasty, sewon had dual functions as a shrine and a place of learning. The site plan of seowon appeared mainly two types of site plan according to the indications of the age and school. This paper was done to analyze the site plan and construction history of Simgok seowon with historical materials and excavation investigation result. Simgok seowon is dedicated to Jo Gwang-jo(1482~1519). This private Confucian academy was founded in 1605 as a small shrine, which was destroyed in 1636. Thereafter, when the shrine received a royal warrant naming as Simgok seowon in 1650, the new site for the seowon was chosen, which is currently located in Gyeonggi-do Yongin-si Sanghyeon-ri 203. Since then, buildings of Simgok seowon was constructed and repaired couple of times. Through the investigation, it was found that the site plan of Simgok seowon was originally a type of 'jeonjaehudang', that is, dormitory building between the lecture hall and the outer gate, or dormitory building is in front and lecture hall is in behind.
