Clothing, as a signsystem, implies many different meanings according to different circumstances. Korean fashion designers’ designs also imply various meanings. Therefore, the purpose of this study is the exploration of Korean fashion designers’ design characteristics through Greimas’ Semiotic Square. As sublimity is the most representative characteristic of modern fashion design, this study discusses the in-depth aesthetic meaning innated in Korean fashion design through the semiotic square proposed by Greimas. To fulfill this goal, Korean fashion designers were sought after on the internet; consequently, four Korean designers became subjects for the analysis. Their collections were analyzed according to predefined criteria adopted and modified from previous studies. Sublimity characteristics were applied to Greimas’ and Floch’s semiotic squares for further interpretation. Results of the study indicate that sublimity, which is typically found in Korean fashion designs, varies depending on different points of view. In terms of culture, this study discovered a relationship of contrariety between sublimity and beauty. This finding opposes the theory of Greimas’ semiotic square, in which sublimity stands as a contradictory of the technician. According to the culture industry theory, suggested by Held, the technician is an implication of sublimity. Through a technician, sublimity may pose as a complementarity or implication of beauty. Finally, sublimity might substitute beauty as well; furthermore, it constitutes practical valorization in the semiotic square of Floch. Moreover, the artist present as a ludic valorization stands as a contradictory, while art, serving as a utopian valorization, enacts as a contrary.

본 연구는 감마스펙트럼 비율을 이용한 매립된 선원의 깊이 평가방법 개발 및 적용성 확인을 위해 진행되었다. 이를 위해 현장측정 HPGe 계측기 및 MCNP 전산모사를 이용하여 137Cs, 60Co, 152Eu 선원의 매질 내 깊이와 계측거리에 따른 Peak to Compton, Peak to Valley 비율(Q)의 변화를 평가하였다. 해당 결과를 이용해 계측거리 50 cm를 기준으로 PTV 및 PTC 비율(Q)과 매립 선원의 깊이 간의 상관 식을 도출하였다. 그리고 PTC 및 PTV 방법 이용 시 계측거리 변화에 따른 민감도를 평가한 결과, 50 cm 기준으로 계측거리가 20 cm로 감소할 경우 오차가 3 ~ 4 cm까지 증가하였다. 하지만 100 cm로 증가할 경우 계측거리에 의한 영향이 미미함을 확인하였다. 그리고 PTV 및 PTC 방법과 피크 영역의 계수율 변화를 통해 선원의 깊이를 평가하는 Two distance measurement 방법을 상호 비교하였다. 평가 결과 PTV 및 PTC 방법은 최대 1.87 cm의 오차, Two distance measurement 방법은 최대 2.69 cm의 오차를 나타내어 PTV, PTC 방법의 정확도가 비교적 높음을 확인하였다. 선원의 수평 방향 위치 변화 민감도 평가 결과 Two distance measurement 방법은 선원이 off-center 방향으로 30 cm 이동하였을 경우 최대 오차가 25.59 cm로 나타났다. 반면 PTV 및 PTC 방법은 최대 오차 8.04 cm로 현장 적용 시 높은 정확도를 나타낼 것으로 예상된다. 그리고 PTC 방법은 동일 시간 측정 시 다른 방법과 비교하여 낮은 표준편차를 나타내 신속한 평가가 가능할 것으로 기대된다.

Natural frequency changes of an in-service concrete bridge have been monitored to analyze the dynamic characteristic according to temperature and embedded depth changes. 7 acceleration sensors are attached to the bridge, and 11 time impact experiments have been done using the impact hammer. The natural frequency has a trend to drop as the surface temperature of the body goes up. And it also has a trend to decrease as the embedded depth of the bridge foundation increases.

The GFRP shear reinforcement is manufactured into a plate shape with several openings, and it is embedded into concrete with longitudinal steel reinforcements during construction stage. In this paper, the performance of the newly proposed shear reinforcement was investigated by carrying out a structural test on four concrete deep beam specimens. Test parameter is shear span-to-depth ratio, and the cracking pattern, failure mode and the effects of this parameter on the shear strength were examined.

This study suggests a method for estimating embedded depth of a scoured bridge foundation using inverse analysis with natural frequency, that is a lot affected by soil stiffness around the structure. And applicability of the inverse analysis is performed by comparison of test results
