This study evaluated how folly is experimented in the contemporary architecture after 30 years when Bernard Tchumi first introduced it to the public by the modern transformation as a garden ornament. First, folly project has been carried out based on the general concept of energizing dwindling cities. However, it has changed to the direction of adding specific programs. Also, along urban regeneration that does not change deterioration of previous structures, Folly changed in the emphasis on readjust existing structure. Second, by having different designers presenting their own follies during the Osaka Expo, folly now has part on visual exhibition element. This has similarity with public art project, yet it could more actively intervene for urban regeneration compared to conventional environment sculpture. Third, folly is experimented as the event-installation art combined form of architecture and art where people could experience the space and enjoy art. Fourth, folly enabled the landscaping of architecture and expanding city planning. Recently Gwangju Folly invited various arts, social, and cultural professionals to converge city design with architecture, landscaping, and other diverse genres.

Gwangju Metropolitan City has implemented a creative regeneration project of Gwangju Folly in the site of Gwangju-eup Fortress as part of the Gwangju Design Biennale by inviting well-known international architects. This study examined and analyzed the characteristics of location, place, and space through actual survey. The results were as follows. Gwangju Folly were mainly located at the four gates and corners of Gwangju-eup Fortress, main entrances of Asia Culture Complex, and historical places where the May 18 Democratization Movement occurred. The common place of Gwangju Folly was a footpath and common location types were the full location of footpath width and the partial location of footpath width. For the spatial types of Gwangju Folly, the practical type which people can stay was the most common(2/3). In the partial location of footpath width, the type which people take a rest and look out over the surroundings accounted for a half. In the full location of footpath width, the gate type which people pass accounted for 2/5. However, as footpath width was minimum for walking, both partial and full occupation types were narrow in place. It influenced the image of Gwangju Folly. Gwangju Folly did not play as a figure and show architects' intentions clearly because of their narrow locations. Therefore, it is very necessary to make a plan to maintain places so that Gwangju Folly do not have a cramped image and architects' intentions become clear with citizens' cultural competence. Also, urban property which creates the identity and attraction of Gwangju continuously should be settled down through helping citizens recognize the intention and value of artistic works.

Urban regeneration, which implies a certain type of change from what has previously existed, requires fundamental understandings of previous problematic ways of thinking for a meaningful change, as well as a new philosophy that is thought to support that change. This means a change in philosophy is needed to discuss 'newness' in urban regeneration. From this perspective, this paper explores the philosophies which shaped traditional cities as well as a philosophy that may be able to suggest changes to contemporary cities. This paper further proposes contextual novelty as necessary to pursue. This contextual novelty does not deny modern cities' problems but embraces them and carries them into contemporary cities. Arguing for qualitative novelty, this paper argues that contextualism, which explores the complex relationships of direct and indirect contributors of a given event, can help us to understand contemporary cities' heterogenic characteristics. In this context, this paper discusses the concept of novelty in contemporary discourse of urban regeneration by using the philosophy of contextualism. Finally a recent example of urban regeneration in the city of Gwangju, South Korea is interpreted using the concept of contextual novelty.

Browning intensity is a major factor to estimate the quality of red ginseng or red ginseng products. The Maillard type of browning reaction proceeds nonenzymatically during extraction and concentration of red ginseng. The present studies were carried out to investigate the effects of amino acids and sugars on the browning reaction during extraction and concentration of red ginseng. Red ginseng was pulverized to 115 mesh and then tenfold (v/w) of water was added to the powder to make the substrate of red ginseng. Solution (0.1 M) of fourteen amino acids and of folly silgars were added to the substrates of red ginseng powder and these were then extracted and concentrated to examine their browning intensities. Amino acids were more effective than sligars in acrelerating the browning reaction. Acceleration of the browning reaction in the concentrate was in the order of arginine> histidine>glycine>alanine>lysine phenyl alanine>aspartic acid>lelicine>threonine>gllitamic acid>tyrosine>valine>istleucine>methionine for amino acids, and was glucose>frlictose >silcrose, maltose for sugars.

As building becomes larger, taller and more complex due to industrialization and urbanization, it tends to be vulnerable to fire and establishment of effective measures for fire safety is demanded. Especially the fact that the smoke hinders evacuation and fire-fighting activities as well as becomes the major cause of life casualty emphasizes the importance of smoke control system. To design and operate the smoke control system success folly, it is necessary to analyze and predict precisely the thermoflow induced by fire in building. The unsteady three-dimensional analysis of thermoflow induced by fire with diverse variables such as building structure, fire conditions and smoke control facilities can be effectively carried out with numerical method In this study, using the FDS(Fire Dynamics Simulation) program that spreads widely as the analysis tool for thermoflow of fire, the analysis of thermoflow in partition of building induced by fire and comparison with the experimental results for assessment of numerical analysis are presented.

광주비엔날레를 통해 조성된 폴리는 역사성과 장소성을 강화하고, 공동화 되어가는 구도심을 활성화하는 도시 재생적 목적이었다. 그러나 이러한 애초의 목적과는 달리 옛 읍성 터 가장자리에 조성된 10여개의 폴리는 주변 상인들에게 피해를 주거나, 보행자에게 불편을 초래하며, 활발한 이용 대신 방치되어 있는 등 많은 문제점들을 드러내고 있다. 본 연구는 이러한 부정적 현상에 대한 원인을 파악하고, 폴리와 주변공간을 활성화하여 도시재생의 역할을 수행할 수 있는 방안을 제시하고자 하였다. 연구결과, 각 폴리들 간의 물리적 통일감을 부여하는 맥락이 없으며, 각각의 독립된 작가 중심의 작품으로 주변 환경에 대한 이해의 부족, 그리고 폴리 형성과정에서 시민과의 교감이 부족하였던 것으로 나타났다. 이러한 문제점들을 해소하고, 폴리조성 본래의 목적을 수행할 수 있는 결정적 해법으로써 폴리에 인간의 활동을 적용하는 것이 필요한 것으로 도출되었다. 따라서 본 연구에서는 그러한 인간 활동을 적용하는데 있어서 효과적 방안으로 스트리트 퍼포먼스(street performance)를 제안하였다. 원래 폴리라는 시설물은 어떠한 특정 활동이 정해진 공간이 아니나, 현재와 같이 그것이 이용되지 못하고, 외면 당하거나 방치될 때 스트리트 퍼포먼스의 적용은 부정적으로 문제시 되고 있는 광주폴리에 새로운 관계맺음, 창의적인 활동의 무대, 일상의 공간 등의 영역으로 탈바꿈할 수 있는 실질적인 대안이 될 수 있다. 현재 광주시가 최근 선보인 2차 폴리는 도서관, 화장실과 같은 명확한 목적을 가진 구조물 및 소규모 이동식 포장마차 등으로서 1차 폴리와는 그 성격을 달리하고 있다. 그러나 1차 폴리는 개관을 앞 둔 국립아시아문화전당 주변에 위치하고 있으며, 이동이나 철거가 되지 않고, 일부 폴리는 직접 아시아문화전당을 전망할 수 있는 설치물임에 따라 이들 폴리에 대한 지속적이며 효율적 활용이 필요하다. 또한, 향후 계속될 100여개의 폴리 설치계획에 의미 있는 지침의 역할을 할 것으로 기대한다.

The isolation of volatile compounds by vacuum-distillation with freeze-drying was tested 1 with fresh ginseng roots. The roots were frozen at-8$0^{\circ}C$; they were dried at-4$0^{\circ}C$ tinder vacuum(40 tory), for 24 hours; and the ice condensed at the silrface of condenser in the freeze-dryer was thauved at room temperature. The ether extract of the resulting aqueous solution was analyzed by gas chromatography (GC) equipped with a flame ionization detector (FID) or a nitrogen-phosphorils detecto(NPD) and by gas : chromatography/mass spectrometry(GC/MS). More than forty peaks were observed in the CG(FID) profile. and more than ten peaks were observed in the GC(NPD) profile. Among them, thirteen components 1including one aldehyde, four hydrocarbons, two esters, folly alcohols, and two vyrazines were identified: six components the molesuiar ions of which were m/z, 204 were estimated to be a series of azulene compounds; and the other components unidentified were estimated to have molecular weights of lower than 254. Therefore, the freeze-drying technicue is thought to be usefu1 for the isolation of volatile compounds of such low molecufilar weights from vegetables, fruits and biological fluids as well as fresh ginseng roots under the tested conditions.

KOGAS(Korea Gas Corporation) uses two-type vaporizers to send customers natural gas with imported LNG. In winter season, SMVs(SubMerged combustion Vaporizers) are mainly operated due to low seawater temperature. SMVs consume the natural gas of 1,520 $Nm^3/hr$ and emit a lot of $CO_2$ in winter time. If carbon taxes are activated on climate change, the tax burden will be severely heavy. Accordingly this work carried out numerical simulation with a commercail CFX code to investigate its possibility on the practical use of pure oxygen combustion of SMVs to reduce $CO_2$ and to improve its efficiency. First, a nozzle of a SMV's combustor is modelled. The combustion characteristics of Air/Fuel and Oxygen/Fuel are analyzed under folly insulated condition. Although we couldn't find the carbon reduction and the efficient elevation when the pure oxygen/fuel type was compared to the existing air/fuel one, we need a further study to investigate the effect of $CO_2$ recirculation.

Although small but eye-catching outdoor constructions are generally called follies in contemporary architecture, French landscape researchers found different features of the fabrique, which they called separately from the folly. Unlike the 18th-century English gardens, in which the landscape itself was emphasized more than decorative structures in it, French fabriques actively made the atmosphere of picturesque gardens. In this background, this paper, from the architectural point of view, studied the 18th-century garden theories in both Britain and France, which might influence the formation of the fabrique. Then, it tried to analyze the features of French major picturesque gardens and their fabriques, relating them to painting, drama, and culture. In conclusion, this study, focusing on the relationship between the garden and its fabriques or follies, compared the different features between the English landscape gardens and the French picturesque ones in the 18th century.
