폴 푸아레 (1879-1944)가 패션 역사상 혁명적이라고 할 수 있는 여성의 코르셋을 제거시켰다는 것은 익히 알려진 사실이다. 그리고 그러한 결과로 인해 발생된 새로운 직선형의 실루엣에 화려한 색채와 장식을 하여 이전 시대와는 전혀 다른 현대패션의 근원이 되었다. 본 연구는 푸아레의 새로운 직선 실루엣과 화려한 색채와 경이적 장식의 근원이 다름아닌 동양이라는데 중점을 두었다. 이미 국내의 몇편의 논문에서 이러한 논의가 지적되어 왔으나 다른 논제를 다루는 중에 언급이 되었고 당시의 작품이나 동시대의 자료를 분석한 것이 아닌 근래의 출판물에 의존한 연구가 대부분이었다. 따라서 본 연구에서는 그의 동양풍 디자인의 근원을 밝히는데 있어 가능한한 1 차적 자료의 접근을 시도하였다. 1912년 작품인 이브닝 드레스, 터번, 숄, 구두 각 1점과 그의 작품 의도와 생애의 추구를 말해주는 자서전(1930년 불어본 및 1931년 영어본)과 보그(Vogue)지의 기사(1920년 2월호, 9월호) 등을 통하여 그의 동양에 대한 관심을 살펴보았다. 그 결과 푸아레의 동양 영향의 근원은 19세기 말 유럽에서 절정을 이룬 'Sino-Japonism'(중국-일본주의)의 심취, 러시아 발레단의 의상과 색채, 천일야화의 영향에 의한 중동(페르시아)에 대한 열망, 그리고 인도 토민병의 복식에서 비롯된 터번에의 매료 등이었음을 알 수 있었다. 이러한 근원에서 탄생된 디자인으로는 직선형의 튜닉, 기모노 소매(처음엔 푸아레 자신도 중국의 것으로 혼동을 하기도 했지만), 하렘팬츠, 비대칭적인 카프탄식의 코트, 원색의 사용, 극동지역의 직물과 문양, 술장식, 터번 등으로 나타내었다. 따라서 폴 푸아레의 동양적인 관심은 단지 개인적 '취향 혹은 취미(taste)'가 아니라 한 시대양식으로 자리잡은 '동양주의(Orientalism)'라 할 수 있으며 이러한 푸아레의 동양주의는 당시의 패션에 있어 신체의 선을 부정하여 코르셋을 제거 시키게한 그의 모더니즘의 근거가 된다. 본연구의 제한점으로 1차적 자료를 수집하는데에 있어 보다 폭넓지 못했던 점을 밝혀둔다.

In this paper, vertical earth pressure by CANDE program is compared with that by some equations such as the equation by Janssen, Marston, Spangler, and Handy to calculate vertical earth pressure with respect to several factors acting on a rigid buried-pipe filled cohesionless soil. As a result of comparative analysis of vertical earth pressure with each equation, primary factors are affected by backfill width, backfill depth and wall friction. Moreover, vertical earth pressure is linearly increased with backfill depth and width from results of the finite element method. Handy's Equation is reasonable for finite element method while Marston equation is overestimated in case of the design of buried-pipe and box.

This study is about literature of Gosan Yn Sun-do(孤山 尹善道) and his life that haunted Gang-ho(江湖) natures and political realities repeatedly, Especially, it considers what aspect of cognition he had about two realities, Gang-ho(江湖) and the Imperial Court(朝廷) and how it throws image on his works. And through these, it is examined what his viewpoint of literature is. First of all, through a memorial to the Throne that put him in first political trial, we can know that he was so strict that he didn't compromise with political realities and at the same time, he has a strong political inclination hidden behind his character. These two aspects are reflected on his works as his confrontation will and his agony between the two realities two realities. And through analysing the contents of <金鎖洞記> tt recollect landscapes of 金鎖洞 where Yun Sun-do mostly stayed, it can be found that his total viewpoints of nature is complacency. This complacency including the satisfaction of Gang-ho life and his ethics is intactly reflected on his works. Finally, it is clearly revealed that he tried to embody the principle of nature and ethics in his literary works and his reference to the literary as well.

New experimental method to measure solid descending velocity in a vertical downcomer was presented and effects of downcomer diameter and particle properties on descending velocities for Geldart group A, B, and D particle have been measured and investigated. The effect of initial solid inventory on solid descending velocity was negligible. However, solid flow rate, solid circulation rate and solid descending velocity increased as the downcomer diameter increased. Moreover, solid descending velocity increased linearly as the downcomer diameter increased and showed distinguishable trend for Geldart group D particle from Geldart group A and B particles. Empirical correlations of solid descending velocity for Geldart group D and Geldart group A and B particles have been derived based on the measured values. The correlations could predict well the solid descending velocities.

Currently, as we enter the 21st century, the level and interest of society, culture, economy, and science are rapidly developing, but science education is still struggling. In order to increase the efficiency of science education, it is most important to focus on elementary education based on basic science. Therefore, this study aims to analyze the main causes of Korea's science museum's regression as a museum focusing on experience, interest, and fun such as simple science experience centers and science theme parks. To this end, the influencing factors were identified by applying the algorithm of the actor-based model based on the data on the exhibition space and the exhibition movement of the science museum completed and operated in Korea over the past 5 years, and the problem of the visitor movement in the exhibition space was analyzed through the space system. In this study, it was confirmed that the exhibition environment was the best when the linear plot movement system and the picalesque plot were applied simultaneously in the museum's exhibition narrative theory, and the arrangement of major exhibition spaces, width of exhibition spaces, and separation of spaces for exhibition purposes were derived.

Some iron(III)porphyrin complexes were prepared, and identified by the spectroscopic methods. Elution behavior of iron(III)porphyrin complexes was investigated by reversed-phase HPLC. The optimum conditions for the separation of iron(III)porphyrin complexes were examined with respect to flow rate and mobile phase strength. These complexes were successfully separated on NOVA-PAK $C_{18}$ column using methanol / water(95/5) for $[T_pCF_3PP)Fe(R)]$ and methanol / water (98/2) for $[(P)Fe(C_6F_5)]$ as a mobile phase. It was found that these complexes were largely eluted in an acceptable range of capacity factor value ($0{\leq}logk'{\leq}1$). The dependence of the capacity factor (k') on the volume fraction of water in the binary mobile phase as well as the dependence of k' on the liquid-liquid extraction distribution ratio$(D_c)$ in methanol-water / n-pentadecane extraction system showed a good linearity. It means that the retention of iron(III)porphyrin complexes on NOVA-PAK $C_{18}$ column is largely due to the solvophobic effect. Also, there was a good linear dependence of the capacity factor(k') on the column temperature and enthalpy calculated by van't Hoff plot. From these results, it was confirmed that the retention mechanism of iron(III)porphyrin complexes in reversed-phase liquid chromatography was invariant under the condition of various temperature, and the solvophobic binding process exhibited isoequilibrium behavior.

단련용 다결정 Ni기 초내열합금은 우수한 가공성, 내산화성, 고온특성 등으로 가스터빈 연소기, 디스크, 증기발생기 전열관 등 발전용 고온부품 소재에 널리 적용되고 있다. 최근 발전설비의 고효율화를 꾀하기 위해 작동 온도를 현격히 증가시키는 기술방향으로 발전하고 있고, 소재측면에서는 기존의 초내열합금 대비 고기능성을 확보할 수 있는 차세대 Ni기 초내열합금 개발이 유럽, 미국, 일본, 중국 등을 중심으로 활발히 이루어지고 있다. 이러한 소재의 고온강도 (온도수용성)를 향상시키기 위해서는 통상 규칙격자 금속간화합물인 $Ni_3(Al,Ti)-{\gamma}'$상의 분율을 증가시킬 수 있지만, ${\gamma}'$상분율이 증가할 경우 용접 및 후열처리 동안 용접열영향부 (HAZ)에서 액화균열이 발생할 가능성이 높아진다. 결정립계를 따라 발생하는 HAZ 액화균열은 입계특성에 의해 크게 영향을 받을 것으로 판단된다. 한편, 본 연구자들은 최근 입계 serration 현상을 단련용 합금에 도입시키는 특별한 열처리를 이론적 접근법을 통해 개발하였다. 형성된 파형입계는 결정학적인 관점에서 조밀 {111} 입계면을 갖도록 분해 (dissociation)되어 낮은 계면에너지를 갖게 됨을 확인하였으며, 입계형상 변화뿐만 아니라 탄화물 특성변화까지 유도하여 크리프 수명을 기존대비 약 40% 정도 향상시킴을 확인하였다. 이러한 직선형 입계 대비 'special boundary'로 간주되는 파형입계가 도입될 경우, HAZ 결정립크기 변화 및 액화거동에 미치는 영향을 고찰하고, 아울러 입계특성 제어가 용접성/용접부 품질 향상에 기여할 수 있는 가능성도 토의하고자 하였다. 본 연구에서는 재현 HAZ 열사이클 시험을 통해 미세구조를 정량적으로 비교하였다. 상대적으로 입계구조가 안정된 파형입계의 이동속도가 高계면 에너지를 갖는 직선형 입계보다 느려 HAZ 결정립 성장이 효과적으로 억제됨을 확인할 수 있었다. 입계 액화거동을 살펴보면, 두 시편 모두 $M_{23}C_6$, MC 등 입계탄화물 계면이 빠른 승온중 액화반응 (constitutional liquation)에 의해 입계가 액화되었으며, 이후 급냉에 의해 입계에 액상막이 존재한 흔적이 발견되었다. 최고온도별로 입계액화 폭/비율을 정량적으로 비교한 결과, 파형입계가 직선입계 대비 대체로 낮음을 확인할 수 있었으며, 때때로 액화되지 않고 잔존하는 입계 탄화물이 관찰되었다. 재현 HAZ 미세조직을 통해 Hot ductility 시험 결과를 유추하자면, 파형입계가 직선입계 보다 좁은 취성온도영역 (Brittle Temperature Range)을 나타낼 것으로 예상되어, 입계특성제어에 의해 Ni기 초내열합금의 용접성을 향상 가능성을 확인하였다.

Sewage separation which often involves installing a new pipe to separate wastewater flow from stormwater runoff flow can be costly and depends highly on its feasibility in a site. To be able to develop a potentially more economical alternative that can also lessen major road traffic disturbance during this process, a different approach where a smaller sewage separator pipe is installed inside an existing combined sewer pipe was investigated. A small-scale of a box sewer and the proposed sewage separator pipe was constructed in the laboratory to observe and compare the deposition of solids and other solid-associated major pollutants at different flow rates. In addition, three-dimensional flow simulations considering five different scenarios were conducted using Ansys Fluent to observe the effect of the proposed sewage separator pipe to the hydraulic flow if installed inside the combined sewer pipe. Results revealed that the deposition of TSS, TCOD, TN, and TP were reduced by at least 60% when the wastewater was conveyed by the sewage separator pipe instead of the combined sewer pipe. Moreover, the flow simulations conducted showed that there was little to no major disturbance in hydraulic flow and velocity distribution when the sewage separator was installed inside a straight pipe and even at pipe transitions such as intersections, turns, and drop in elevation. Considering the pipe dimensions and the results of the study, the proposed approach can be promising in terms of reduction in pollutant deposition without a major effect on the hydraulic flow. Further investigation and cost-analysis should be done in the future to support these preliminary findings and help alleviate the problems caused by combined sewer overflows by introducing an alternative approach.

Sixteen organochlorine pesticides extracted out from the crops and cleaned by solvent-solvent partitioning and Florisil column chromatography were determined by gas-liquid chromatography. The majority of the pesticides were well separated by being eluted through 5% QF-1 column and some of them through 3% OV-17 column and 2.596 DC-200/2.5% QF-1 column, and the eluted pesticides were detected by $^{63}Ni$ electron capture detector. The linear calibration curves were obtained for the most of pesticides while some curves were slightly deviated from the linearity. In the determination of 16 pesticides added to thirteen kinds of crops, the recoveries were showed over 85% for the most cases and the relative standard deviations of 5 analyses were less than 12.1%. The results were within the criteria of the AOAC method.
