  • 96년 미국과 멕시코로 루이스 칸과 바라간 등의 건축 답사를 다녀온 후로, 우리 전통 문화유산을 두루 보러 다녔다. 그동안 가까이 있는 것은 언제건 보겠거니 하고 미뤄 온 터라, 우리 것을 너무 도외시해 온 것 같은 자책감이 생겼기 때문이다. 그리고 건축관에 변화가 있는건 아니지만, 답사하면서 이따금 좋은 느낌을 만나 반가웠다. 솔직히 말해서 다 그런 것은 아니고 손꼽아 말할 수 있었다. 그러면서 필자는 건축적 가치의 획득이 고전과 현대 또는 양식의 차이에 의해서가 아니고, 자체의 성공 여부에 있다는 것을 확신하게 되었다. 건축의 본질은 변함없으며, 건축에 반영된 시대 상황이 다를 따름이라 생각한다. 우리는 훌륭한 문화유산을 많이 갖고 있다. 하지만 국가나 개인의 살림이 넉넉해서 그렇게 되어졌다고 생각지는 않는다. 종묘가 만들어진 것은 정신적 힘에 의해 이룩됐을 것이다. 그렇게 해서 지금 우리에게 위대한 모습으로 남겨 있는 것이 감사하다. 전통건축은 현대 사유 체계로는 추구될 수 없는 이상적인 모습을 띠고 있다. 그리고 오늘날 건축의 자본주의 행태와 대조되는 교훈도 느낀다. 도대체 우리 선조들에게는 구도하듯 짓는 어떤 전통이 있었기에 그렇게 훌륭한 건축이 남겨질 수 있었을까? 그 흔적을 나름대로 찾아보고자 한다.

  • Graphene is a nanomaterial and is known to have very high mechanical strength, thermal and electrical properties. However, graphene is known to be difficult to disperse among carbon-based materials due to van der Waals force. In this study, to solve the dispersion problem of graphene nanoplatelet, oxidized graphene nanoplatelet was prepared by oxidizing GNP in nitric acid. The prepared GO was dispersed in ethanol and distilled water before incorporation into the epoxy paint to confirm dispersibility. In addition, GNP/Epoxy and GO/Epoxy tensile specimens were prepared by mixing GNP and GO at 0.1, 0.3, 0.5 and 1.0 wt.% In epoxy coatings and tensile stress-strain characteristics were investigated.

  • 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.

  • This study is to interpret how landscape aesthetic characteristics of moderation, which is the point of human-oriented neo-confucianism vision, are projected to the landscape organization of a Dodong-SeoWon, known for its overflow to neo-confucianism grounds and standards among domestic SeoWon. The aspects of neo-confucianism discussion in the shape of Dodong-SeoWon with the beauty of from and contents dominating the landscape of Dodong-SeoWon different from constructive completeness as 7 external and internal landscape organization including placement, circulation, setting, vista, fencing, naming, and decoration are as follows. The left direction of Dodong-SeoWon, part of external organization, is the result of landscape organization that emphasized the stage of moderation through the unification of man and nature by naturalizing natural direction to human-oriented directions. Important aspects to rule external orders and standards of Dodong-SeoWon are principles of one classes based on ranks and bilateral symmetry that is the unity of setting and circulation landscape organization from penetrating the spirit of moderation with no bias. By securing territoriality by fencing the unity of verticality and horizontality, the landscape organization to reach moderation is expressed. Meanwhile, Suwoloo(水月樓) perceived on the floor of central assembly hall, the formation of time frame from roof piles of Hwanjumun(喚主門) as well as pilars of Jungjeongdang(中正堂), and rime link method inducing visual balance and openness through segment, combination, and others are vista organization that show the ideality of unique neo-confucianism building. Also as part of landscape organization contents. semantically, building name including arrangement from Taegukdoseol, ideological naming following the name of Ssanggye-SeoWon, which is the former body, the name of the hall symbolizing the transfer of neo-confucianism enlightenment, impartiality with no bias, as well as Geoinjae(居仁齋) and Geoijae(居義齋) based on olympic, are also results of applying neo-confucianism standards. Additionally. the SeoHoe(瑞花) expressing the change of IleumIlyang(一陰一陽) on the stylobate of Jungjeongdang, Saeho(細虎) which goes up and down, as well as Simul made of four dragons, are artistic expression of the moderation that symbolizes the harmony of ying and yang with no exceeding or insufficiency. Humorous and unique rocks and stones evenly arranged in all spots of Dodong-SeoWon are to promote anti-strict organization by offsetting the image and external order of the lecture hall as strict as it is, and this is very ironic as it is the other landscape organization in different dimension as well as the expression of moderation.

  • Transparency orginated from a visual character of the object recognized to the backside without any obstacle is used as a word explaining the variety of an architectural character from the pre-mordern architecture. Transparency is expressed clearly without using of the material with a permeability like glass in the Korean traditional architecture. Thus the purpose of this study is to analyze an expression of the perceptive transparency focusing on the Dodong Seowon with the phenomenal transparency. In chapter one, the background, purpose and method of study are explained. In chapter two, general concept of transparency is inquired. In the process of searching for the formation of basic background, the characteristic of phenomenal transparency is recognized. In chapter three, the aspect of phenomenal tranparency expression in Korean traditional architecture is inquired. In chapter four, with the characteristics drawn from chapter three, the characteristics of Dodong-Seowon under its phenomenal tranparency are shown. In chapter five, synthetic conclusion is presented.

  • 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.

  • The purpose of this study was to investigate the characteristics of Chinese seowons and to obtain data based on the characteristics of waterscapes unique to Korean seowons. The conclusion of this study from the results of investigation and analysis of the location, water system, and design characteristics of 10 representative traditional seowons in China including Yuelu Seowon(嶽麓書院) conducted based on literature research and field observation is as follows. The water system of Chinese seowons is dualized into an inner and an outer water system, and in general, two and a maximum of three water bodies are superimposed on the outside. The locations of seowons are classified into five types: Four double-sided round water type sites, three converted face water type sites, one three-sided round water type site, a four-sided round water type, and a waterproofing type(依山傍水型). Therefore, compared to the typical Korean seowon facing water in the front and a mountain in the back(背山面水型), the Chinese seowons showed a highly hydrophilic property. The water shapes of the external water system were meandering(46.0%), mooring(36.0%), and broad and irregular(9.0%). In addition, water conception(水態) were streams(31.8%), rivers(27.3%), springs(13.6%), falls(9.1%), lakes(4.5%) and ponds(4.5%), in that order. As for waterscapes of the water system inside the seowon, there were seven in Akrok Seowon and four in Mansong Seowon, indicating a comparatively higher number of waterscapes. Since the 27 detailed waterscapes in 10 seowons that were the subject of the study were classified into six types including ponds and half-moon ponds, they appeared to be more diverse than the Korean seowon. It is noteworthy that in the interior waterscape of the traditional Chinese seowon, the ritualistic order, where at least one half-moon pond or square pond(方池) was arranged, is well displayed. In particular, the half-moon pond(伴池), which is difficult to find in Korean seowon, was found to be a representative waterscape element, accounting for 42.8%. If the square pond of Nanxi Seowon based on Zhu Xi's poem 「Gwanseoyugam(觀書有感)」 is also treated as a square-shaped half-moon pond, the proportion of half-moon ponds in the waterscape will be as high as 50%. The pond shapes consisted of 28% square, 24% each for free curve and round shape, 20% for semi-moon shape, and 3.8% for mountain stream type. This seems to differ greatly from the square-shaped Korean seowon. On the other hand, there were a total of 10 types of structures related to the waterscape inside the Chinese seowon: 11(26.8%) pavilion and bridge sites, five gate room sites(牌坊: 16.5%), four gate and tower sites(樓, 1.4%), two Jae sites(齋, 6.2%), and one site each(3.1%) of Heon(軒), Sa(祠), Dae(臺), and Gak(閣). In particular, the pavilions inside seowon were classified into three types: landscape pavilion(景觀亭 27.2%), tombstone pavilion(碑亭, 18.2%), and banquet pavilion(宴集亭, 54.5%). In general, it was confirmed that the half-moon pond with a pedestal bridge, and the pavilion were the major components with a high degree of connection that dominate the waterscape inside the Chinese seowon.
