The creation of clothing is a form of aesthetic expression through which feelings and ideas are conveyed. This study tried to find out the mental world and aesthetic consciousness of Ancient Egypt through the costume of the period. The beauty of human body was esteemed and expressed in body exposure, tight costumes and transparent fabrics. Through the silhouette of costume, wig and accessories, the beauty of simplicity was expressed. And the beauty of harmony was sought through the beauty of balance and emphasis. The aesthetic consciousness of Ancient Egypt is the refined elegance and it was composed on the basis of the ideas of nature worship and had been preserved by the spirit of traditionism for about 3, 000 years.

2012년 상용화가 목표인 국내 위그선 개발은 화물운송과 여객운송에 큰 변화를 가져올 것으로 판단된다. 특히 부산은 일본과의 여객에서 수요가 클 것으로 판단되며 이에 2012년 이후 상용화에 위그선 터미널 등 관계시설을 계획할 필요가 있지만 현재까지 북항재개발계획에 포함시키자는 단순 논의만 있을뿐 뚜렷한 계획이 없는 실정이다. 위그선의 경우 속도가 빨라서 현실적으로 북항지역에 터미널을 생성시 어려움이 있을것으로 판단되며 이에 현재 영도 동삼동 크루즈터미널이 북항재개발 지역에 신규 크루즈터미널이 만들어진 후 여유가 있을것으로 판단되어 이를 활용화할 필요가 있다. 이률 위해 영도 태종대와 롯데월드를 잇는 관광벨트와 부산역과 연계된 열차화물수송을 적극 활용할 수 있게 영도 경전철을 고려해 볼 필요가 있다.

Recently, there has been a serious effort to design a wing in ground effect (WIG) craft. Vehicles of this type might use low aspect ratio wings defined as those with smaller than 3. Design and prediction techniques for fixed wings of relatively large aspect ratio are reasonably well developed. However, Aerodynamic problems related to vortex lift on wings of low aspect ratio have made it difficult to use existing techniques. In this work, we firstly focus on understanding aerodynamic characteristics of low aspect ratio wings and comparing the results from experimental measurements and currently available numerical predictions for both inviscid and viscous flows. Second, we apply an improved numerical method, "B-spline based high panel method with wake roll-up modeling", to the same problem.

The iterative boundary element method (IBEM) developed originally before for cavitating two-dimensional (2-D) and three-dimensional (3-D) hydrofoils moving under free surface is modified and applied to the case of 2-D (two-dimensional) airfoils and 3-D (three-dimensional) wings over water. The calculation of the steady-state flow characteristics of an inviscid, incompressible fluid past 2-D airfoils and 3-D wings above free water surface is of practical importance for air-assisted marine vehicles such as some racing boats including catamarans with hydrofoils and WIG (Wing-In-Ground) effect crafts. In the present paper, the effects of free surface both on 2-D airfoils and 3-D wings moving steadily over free water surface are investigated in detail. The iterative numerical method (IBEM) based on the Green's theorem allows separating the airfoil or wing problems and the free surface problem. Both the 2-D airfoil surface (or 3-D wing surface) and the free surface are modeled with constant strength dipole and constant strength source panels. While the kinematic boundary condition is applied on the airfoil surface or on the wing surface, the linearized kinematic-dynamic combined condition is applied on the free surface. The source strengths on the free surface are expressed in terms of perturbation potential by applying the linearized free surface conditions. No radiation condition is enforced for downstream boundary in 2-D airfoil and 3-D wing cases and transverse boundaries in only 3-D wing case. The method is first applied to 2-D NACA0004 airfoil with angle of attack of four degrees to validate the method. The effects of height of 2-D airfoil from free surface and Froude number on lift and drag coefficients are investigated. The method is also applied to NACA0015 airfoil for another validation with experiments in case of ground effect. The lift coefficient with different clearance values are compared with those of experiments. The numerical method is then applied to NACA0012 airfoil with the angle of attack of five degrees and the effects of Froude number and clearance on the lift and drag coefficients are discussed. The method is lastly applied to a rectangular 3-D wing and the effects of Froude number on wing performance have been investigated. The numerical results for wing moving under free surface have also been compared with those of the same wing moving above free surface. It has been found that the free surface can affect the wing performance significantly.

이 연구는 현재 개발이 진행 중인 장갑차량 상부 공격용 지능형 탄약을 포함한 155mm 포병 탄약의 전시소요량을 산정하는 방법론을 정립하려는 것이다. 종래의 워게임 시뮬레이션에 의한 방법에서는 장갑표적 공격용 무기체계별 기대점유비율이 지상군 및 공군간에 과도하게 차이가 발생하고 있다. 또한 상향식 소요산정방법은 최소소요량에 비하여 너무나 과도하게 산출하는 경향이 있으므로 이러한 점들을 보완하기 위하여 표적 수량에 따른 무기체계별 할당에 의한 하향식 모형을 구성한 것이다. 이모형이 워게임에 의한 상향식 소요산정보다는 더 믿을 만한 결과를 산출한다.

The quality of an intravenous immunoglobulin preparation (IVIG) is reflected by the degree of nonspecific activation of complements, the so-called anticomplementary activity (ACA). ACA of aggregates in IVIG was investigated using method by the European Pharmacopoeia and Clq-coated microtiter enzyme-linked immunosorbent assay (ELISA). Both the EP method and the ELISA method showed a dose response curve with the amount of complements bound increasing with the percentage content of aggregates in immunoglobulin standard. The correlation between the two tests was good (r=0.96, r=0.99). However, the correlation was not found when the ACA (EP method) of IVIG product was compared with its aggregate percentage. These results emphasize that the method of aggregate formation affects ACA and that estimation of the percentage distribution of aggregates by HPLC may not reflect ACA. In analysing WIG product for Clq binding activity test with the ELISA, the result by using Protein A-HRP correlated with aggregate percentage (r=0.84). But the correlation decreased (r=0.48) when the result used Protein A-AP(having poorer sensitivity than HRP) was compared with aggregate percentage. As a result, some variation between the two methods, due to differences in assay principles, is to be expected. However, ELISA technique has the advantage in that it is easier to perform, more precise and less subject to reagent variability, and is the more suitable screening method than HPLC analysis.

This article studied women's headdresses that appeared in the paintings of Joseon Dynasty. This examined the shapes of women's headdresses painted in genre paintings, record paintings and nectar ritual paintings from Joseon Dynasty and compared them to literatures and relics in order to analyze their types and characteristics. Headdress can be categorized into three types: (1) square cloth worn on the top of the head; (2) a kind of small cap; (3) Cloth that completely covers the head. The first type of headdress resembles the shape of Garima. In the early period of Joseon Dynasty, it was worn not only by Gisaeng, but also by both upper and lower class women. The second type of headdress includes a cap made by connecting several cloths, round cap, and cone-shaped cap. These two types are worn on top of the head. However, sometimes these were worn between the head and the chignon to fix the chignon. Also, these were used as hair accessories for decorative purposes. In particular, old women wore these headdresses and braided their white hair around them to fix the chignon. This way, the headdress not only kept the head warm, but also hid the old women's scanty hair. Headdress was usually made of black fabric and it was a simple hair accessory that replaced the wig. The third type of headdress was widely worn among lower class women. The cloth completely covered the head so that the hair would not fall when working. It also provided protection from cold and hot weather. According to paintings, there were many ways of wearing the cloth around the head.
