This paper is a study of Kim Si-seup's maniacal tendency. The properties of mania can be divided into two categories. One is mental mania wherein the mind has fallen into madness, and the other is morphological mania wherein madness is revealed in real world actions. This thesis analyzes two aspects of the madness of Kim Si-seup, who showed madness in the morphological dimension as well as madness of the mind in the Joseon Dynasty. One notion that is analyzed is 'Longing to never return', and the other is 'To live in obscurity, yet practice wonders.' Kim Si-seup was a promising talent when he was young and was a so-called "infant prodigy." However, when 'Saejo' took the throne of 'Danjong,' he left the house on the road to 'burn all the books' and became a monk as a way of disappearing from the world. Thereafter, Kim Si-seup gave up on the test to become a bureaucrat and lived in hiding while doing strange things while he falsely pretended to be "crazy." He never felt regret hearing others describe him as a strange person. He lived a life of not returning to the mundane world for a long time as he traveled through famous mountains and streams. Also, he pursued a life in 'the world outside the world' without any greed. Sometimes he expresses his own free spirit and madness through poetry with 'what he talks about' and 'wonderful words.' This life was far from a form of neutralization aesthetics achieved by pursuing a 'gentle and magnanimous' life as claimed by Confucian scholars. Kim Si-seup, sometimes referred to as 'a maniac with mental clarity,' directed his efforts at 'false maniacal behavior,' 'weird behavior,' 'life pursuing the world outside the world,' and 'life of breaking off one's relationship with the world.' This maniac-like life of Kim Si-seup was not crazy but conveyed a deep desire to criticize the absurd reality of Joseon society at the time. Regarding Kim Si-seup, Li Hwang criticizes him for wishing 'to live in obscurity yet practice wonders.' Unlike Li Hwang, Yi Yi, who wrote The Records of Kim Si-seup when commissioned to do so by Sun Jo, positively evaluated Kim Si-seup as "a Confucian who followed Buddhism." Although the contents of these evaluations of Kim Si-seup were different, both agreed that Kim Si-seup was a maniacally-oriented individual. Kim Si-seup, who was mentally maniacal and morphological maniacal, represents a unique case in the study history of the Joseon Dynasty, wherein the 'the doctrines of Zhu Zi' exerted great influence.

Bacterial cellulose based actuator with large displacement was developed for biomimetic robots. Bacterial cellulose has 3D nanostructure with high porosity which was composed of the nanofibers. Freeze dried bacterial cellulose was dipped into ionic liquid solution such as 1-butyl-3-methylimidazolium(BMIMCl) to enhance the actuation performance due to increase the ionexchange capacity and ionic conductivity. And Poly(3,4-ethylenedioxythiophene)-poly (styrnenesulfonate)(PEDOT:PSS) was used for the electrodes of both side of bacterial cellulose actuator by dipping and drying method. The FT-IR and XRD were conducted to examine the electrochemical changes of developed bacterial cellulose actuator. The biomimetic caudal fin was designed using bacterial cellulose actuator and PDMS to verify the possibility for biomimetic robot. The step and harmonic response were conducted to evaluate the performance of developed biomimetic actuator.

The purpose of this research was to find out the characteristics of secluded cultural landscapes that were retained by Eyogye Cho Lyeo(漁溪 趙旅) as a recluse or a schola at the early time of Chosun dynasty through his poems, residential site and his successors' landscapes. The study sites were selected such as Wonbukgae(院北齋), Chamijeong(採薇亭), Gomaam (叩馬巖) and his graveyard. In order to do that, Wonbukgae, Chamijeong, Gomaam and his cemetery were selected as studying sites. Also researching methods were used by grasping the landscape elements through reading ancient books such as "Eyogyezip(漁溪集)", field-researching, analyzing characters of his secluded landscapes and interpreting his poem's meaning. This research found that: 1) After Danjong(端宗)'s dethronement, he returned to his home town and never come out to the world again. He wanted to keep fidelity to his king forever. 2) He was affected for his seclusion from many people who were Ryu Gyebun(柳桂芬), Bae Junghu(裵仲厚) as his classmates at Sunggyungwan(成均館). Also Won ho(元昊) and Kim Sisyub(金時習) as members of Sangyuksin(生六臣) affected him for sake of their seclusion. 3) The meaning of his seclusion expressed the notation of seclusion as a fisherman from his pen name as 'Yeogye'. Also this kind culture has very particular behavior such as concentration phenomenon of action, absolute eccentricity of seclusion, tourism of nature and deep knoledge of feng shui, strong persistence of seclusion and confucian practical attitude of filial behavior. 4) The secluded cultural landscape is divided to four regions. They have two types of landscape such as secluded cultural landscape of his lifetime and landscape transmission of his posterity and scholars. 5) The interpretation of his poems and their aesthetic analysis found two characters. His poems were expressed by landscape substance like plants, natural and man-made elements. Their theme was confucian, peaceful and faithful seclusion.

In this paper, Han Yong-un's view point of Buddhism was examined in the traditional Zen Buddhism. He emphasized the essence of calm and awakened Zen in Wonhyo's theory of Jigwanssangun and Jinul's theory of Jeonghyessangsu. He criticized the behaviors of Zen priests at that time who turned their back on common people, secluded themselves in mountains and tried to stay calm in their places, and ideologically stressed that calm and awakened Zen should be realized in disciplinants' daily lives while enlightening the public. On the other hand, he had consistently stuck to Imjeseonpung(臨濟禪風) based on the spirit of saving the world, rather than depending on Jodongowi(曹洞 五位), when glossing "Sip-hyun-dam" with the traditional $S{\bar{o}}t{\bar{o}}$ Zen(曹洞宗) after Kim Si-seup Compared with Jodongowi, Siphyeondamjuhae(十玄談註解) emphasized Pyeonjungjeong (偏中正) where the right position(正位) of a true man(眞人) is founded in the middle of common people's partiality(偏位). In Siphyeondamjuhae, he intended to rebuke Japanese $S{\bar{o}}t{\bar{o}}$ Zen priests' brutality of trying to annihilate even the spirit of Zen Buddhism through Treaty of Alliance of Korea-Japan Buddhism(朝日佛敎同盟條約). Considering Han Yong-un's view point of Buddhism, it has the characteristic of patriotism and love of the people in the traditional Zen Buddhism.

This thesis examined interest and elucidation of Confucian scholars during the Chosun dynasty on the theory of self-cultivation. Taiji is the ultimate notion that surveys existence and value, however, the concern on the Taiji during the Chosun period lies more on the cultivation of mind. Confucian scholars understand the human world as a place for moral completion. Therefore, the self-cultivation theory of Confucianism rises against the disciplines of Taoism and Buddhism which are away from daily lives. And it also makes theoretical basis on the elucidation of Taiji distinguished from Taoist and Buddhist disciplines. The Confucian scholars in the Chosun dynasty saw Taiji as actual truth [實理] penetrating inside and outside and at the same time sincerity. On the discussion on "mind becomes Taiji[心爲太極]", they recognize taiji as a center supervising everything, human ultimate[人極], mind of the Way[道心]. The Confucian theory intending to comprehend tai-chi as a center of silent and stable mind, accepts methods of being calm, sitting in meditation, and breathing exercise at the time of before issuance[未發] This is reinterpreting the discipline methods of Taoism and Buddhism reasonably and including them as the parts of Confucian jing[敬] study.

This study aims to clarify the meaning of the Anapji which was one of the scenic places of historical interest during Silla Dynasty and of the Anapbupyeong(雁鴨浮萍) which was one of the greatest seven miracles (Dong-do-chil-gue(東都七怪) through appearance of the Anapji in poems. Anapji lies its original meanings on Anhaji(安夏池) and then it was shortened to Anji(雁池), apji(鴨池) while Dongho(東湖) has also been called since it is located in the South of Gyeongju. As of July 2011, the Ministry of Culture officially renamed Anapji and Imhaejeon Hall Site(臨海殿址) as the palace of Crown Prince-Gyonegju Donggung(慶州 東宮) and Wolji(月池) (Historical Site No. 18) and Wolji became the current name. While pond was made during Munmu of Silla, the name Anapji did not exist. Kim Si-Seup (1465~1471) in the early Chosun period referred to the pond as Anhaji(安夏池) and its name started being called as Anapji in the Geography of Korea (Sinjeung dongguk yeoji seungnam,(新增東國輿地勝覽)(Jungjong 25, 1530). Though modern scholar states that it was being called Anapji since there are always many ducks and wild geese in the pond, they fails to present the literature evidences. The author found the line in the poem -Anapji composed by writer Kim Chul Woo, which means that a wild duck and water bird get in and off the pond on their own and the record saying which means Dong-ho(東湖) from the phrase of Dongho-saw-sar-gi(東湖書社記) of Lee Su In(李樹仁)(1739-1822)-Confucian Scholar of Gyeongju was created due to the fact that many wild geese and ducks are flying over. Based on the facts foresaid, the literature evidences for the name of Anapji are presented in the paper. Anapji is a combined word between the Anapbupyeong(雁鴨浮萍) which is a flooding weed and Dong-do-chil-gue(東都七怪). Dong-do-chil-gue is an ancient form of Modern Eight Scenic Views. Eight Scenic Views -Gyeongju Parlgyong is just well-known as scenic places without grotesque elements Dong-do-chil-gue had before. However, the author also found the passage of Ilseongnok: Records of Daily Reflections saying that Anapji has a clod that is as wide as rock(盤石) and the clod also has moneywort on, which are undulating in the wind and clarified how the Anapbupyeong became one of the one of the greatest-seven miracles Dong-do-chil-gue and why the Anapbupyeong frequently appears in the poems of many writers.
