건축외피 표현성의 재해석에 관한 연구 : 근대이전 구조와 장식 관계변화 분석을 중심으로 Focused on Analysis of Relationship Change Between Structure and Ornament during pre-Modern times

유진상 대한건축학회 2003 대한건축학회논문집 Vol.19 No.11

The Objectives of this study are to re-illuminate the role of the ornament in pre-modern times through reinterpreting discussions on the ornament and examining the changes in material bases of the ornament as well as to search for the possibility of rational and at the same time expressive modern ornament by reconsidering ornament needlessness and dichotomous classification of the structure and the ornament. Before 19th century, the desire for the expression was manifested mainly through revealing the constructional organization of the structural body, or through the ornaments attached to the structural body. That means, the structure and the exterior envelop were intimately integrated with each other, so that they served for the functions of each other. However, historians' dichotomous classification of the structure and the ornament makes it difficult for ornament to take a new role. As a result of re-examining the existing discussions regarding the structure and the ornaments in the view of integrity, it was possible to understand the both as essential and indispensible elements that satisfies structural rationality and exterior expression. In the early 1900, though it was regarded as the deloaded exterior envelop was abstracted or removed according to the economical and functional demands, actually, ornaments were interpreted and transformed in a new way. The modern architecture was just placed in a transitional period of new interpretation, when the modern architecture could not remove the ornament totally and the society or technology could not accept radically changing material basis in aesthetics.

Thermus caldophilus GK24 was selected as sources of thermostable $\beta$-galactosidase from a survey of genus Thermus. T. caldophilus GK24 (Tca) $\beta$-galactosidase was found to be inducible. The enzyme was optimally active at 75$\circ$C. Enzyme induction was achieved by addition of lactose, galactose and cellobiose to basal media. The addition of glucose to culture media had a repressive effect on further enzyme synthesis. T caldophilus GK24 was tested for production of $\beta$-galactosidase by addition of various concentration of lactose, galactose and cellobiose to standard media. Cellobiose was found to be effective for the $\beta$-galactosidase induction. The optimal induction medium for production of $\beta$-galactosidase was composed of 0.2% cellobiose, 0.3% bactotryptone, 0.3% yeast extract, basal salts and Tris/HCI(pH 7.8). The activity of the enzyme in the optimal induction medium increased nearly 16.5-fold compared to the standard medium. Tca $\beta$-galactosidase was detected when cell extracts was subjected to electrophoresis in a nondenaturing polyacryamide gel and stained for activity with 6-bromo-2-naphtyl-$\beta$-D-galactopyranoside(BNG).

A more efficient method for obtaining the fatigue life enhancement of a structure member with fastener holes is described. It is based on the combined process of cold-expansion and ring-indentation. Residual stresses were induced onto premachined holes using ring-indentation process near the fastener hole combined with cold-expansion. And residual stresses at the vicinity of a hole were evaluated using a fracture mechanics approach. The compressive residual stresses were larger using the combined process than is in the case of simple cold-expansion. Fatigue testing of aluminum specimens showed that the fatigue crack growth retardation emanating from a circular hole was greater for the combined process than for a simple cold-expansion alone.

This thesis aims to analyze user's Preference Tendency so as to prepare in case of dispersing planning Cultural · Sports center which are concentrated in middle area of Changwon, If those new facilities will be built we should design swimming pool, gym, yoga which are popular steadily and culture classroom which can be used other purposes. In addition we need new plans that are different from the existing facilities program's circumstances. Also we analyze that it is reasonable to design squash tennis, ice link, out-side space which are not in the existing facilities to avoid the duplicate investment

In developed countries, they have constructed the integrative transportation system which allows people to use bicycle, subway and train at a time. They also have tried actively to load bicycle in public transportation for using them at the same time. This thesis analyzed the problem and improvement of bicycle loading manners in public transportation to activate the connection system for them in Korea. In some subways and light rail, they have tried to load bicycles in public transportation, most of which are less effective and safe due to using the existing bicycle racks for non-driving. In particular we confirmed that the existing bicycle loading systems which are being used sporadically at the moment may cause expensive bicycles to crash one another and damage passengers in public transportation. The researchers confirmed that just the layout planning can carry 4 to 6 more bicycles than before without altering the existing layout largely through simulation or trial test and we can load bicycles inexpensively and effectively through improving ready made bicycle racks. To summarize as following. 1. In case of subway and light rail, we confirmed that after changing some general seats into handicap seats, we have spare capacity by arranging bicycles at an angle of 45 degrees which can load 3∼4 more bicycles than before. 2. It is better a pillar or a pillar rack style in subway and train. it is also good to change holders into vice type and to widen the space between holders to improve sway control problem. 3. It is possible to load the maximum 3 bicycles by arranging at an angle 45 or 60 degree using floor frame after taking the back door of the bus. But it is not suitable for hanging style because buses are normally narrower and worse swaying is worse than train. 4. It is good flooring rail or wheel holding type for buses. Because we have rear tires of bicycles load the holders which can adjust their height without lifting bicycles so that bicycles can be balanced safely. 5. Changing one of the two ready made holders axis into vice type can improve durability of the holder.

야간주행환경 개선을 위한 자전거도로 일체형 조명방식 연구

The bicycle night driving environment of our city is very poor. If the bike night using rate is enhanced, the public transportation sharing rate will be increased more 20%. This thesis suggests the most effective bicycle lighting design through analyzing bikeway structure beside main streets and night driving patterns. The research indicates that most bikeway night driving patterns rely on the intensity of illumination of the ground. Therefore we suggest bikeway integrated lighting design to improve inefficiency of the existing streetlight way. The integrated design can directly illuminate bikeway floor at the road boundary stone etc. without disturbing upper street trees or losing the intensity of illumination and have caution or warning lightings depending on driving conditions with cheap electric charges.

The management of the natural landscape in national park is getting improved. And its management at boundary of the Park would be more intensive by two institutions ; national Park and local government. But, Because of ambiguity of management authority, this area often is placed in shadow zone. The management of the landscape of Jirisan national park show also same phenomenon. While the collectives facilities districts is well managed in Jirisan park, the improving strategy of the landscape of boundary zone are discussed. This study aims to survey the actuels conditions of the landscape at the boundary area of Jirisna National Park and to suggest the improvement measurements for landscape management. Specially, Sancheong and Hadong area were selected for the survey zone by its dynamics between natural landscape and artificial landscape. First, we reviewed the theories and the cases of the former studies and analysed the legislations and the politics for managing natural landscapes of advanced countries. Secondly, we surveyed five types of landscape and analysed the strengths and weaknesses. finally, being based on the analysis, the strategy of landscape of boundary zone would be proposed. Comprehensives measurements would be required rather the simple management case by case. It contains divers methods ; convergence of tangible-intangible landscape, story-telling method, networking of landscape types. For the success of the measurements, Coorperative governance between differents actors in/around of national park is strong prerequisite.
