Although the motion of the three-phase contact line on a solid substrate has been extensively studied thus far, the understanding of the dynamics of the contact line of liquid/liquid/gas phases is far from complete. Here we deposit a drop of isopropyl alcohol (IPA) on water and HFE-7100 whose free surfaces are exposed to air to observe the flow field around the contact line. By combining the shadowgraph and high-speed imaging techniques, we find that vortices are spontaneously generated at the contact line, which grow in size with time. The flow is attributed to the Marangoni stress that pulls a liquid of lower-surface tension toward a liquid surface having a higher surface tension. However, it is not still clear why the entrained lower-surface-tension liquid should whirl rapidly beneath the contact line. We also visualize the flow by the particle image velocimetry (PIV) to find out that the rotational velocity reaches the order of 1 mm/s near the free surface.

An experimental study was carried out in a channel cavity with square heat surface by visual¬ization equipment with Mach - Zehnder interferometer and laser apparatus. The image processing system consists of one commercial image board slit into a personal computer and 2-dimensional sheet light by Argon-Ion Laser with cylindrical lens and flow picture recording system. Instant simultaneous velocity vectors at whole field were measured by 2-D PIV system which adopted two¬frame grey-level cross correlation algorithm. Heat source was uniform heat flux(o.4W/cm$^2$, , O.8W/cm$^2$, 1.2W/cm$^2$). Obtained result showed various flow patterns such as kinetic energy distribution. Severe unsteady flow fluctuation within the cavity are remarkable and sheared mixing layer phenomena are also found at the region where inlet flow is collided with the counter-clockwise rotating main primary vortex. Photographs of Mach ~ Zehnder are also compared in terms of constant heat flux.

Present expression methods have close relations with popular culture in the active acceptance of various kinds of genre. Fashion illustration is no longer limited to sketching garments or technically explaining construction, it is accepted as an art that is expressed by the desire and consciousness of the artist. This study examines the expressional characteristics and effects of photo-image appropriation as an expression method in fashion illustration. The word 'appropriation' (to steal something) is used as euphemism and not meant to be derogatory. The methods of appropriation in art indicate that paintings are not inventions but are self-satisfactory creations that show that the idea of originality is false and that paintings should be uninhibited from the greed of the authority of the genius of artists. In postmodern paintings, the photo-image of appropriation are expressed through the methods of re-photography, photo collage, and photo painting. Photo-image appropriation methods in fashion illustration are re-photography, photo collage, image mixing of photography, drawing, and graphic expression of photography. Fashion illustrators are able to develop expression techniques for expanding a field of expression and enhance the ability of communication through the photo-image appropriation methods.

하천 합류부는 두 하천이 만나 형성되는 지역으로 합류부 구간의 혼합 매커니즘을 이해하기 위해서는 지류의 다양한 유입조건에 따른 본류와의 수체혼합의 공간적인 패턴을 분석하는 것이 중요하다. 그러나, 대부분의 합류부 연구들은 실측을 통한 현장데이터를 획득하기 어렵기 때문에 수리 및 수질 수치모형을 통한 연구가 주로 수행되어 왔다. 본 연구에서는 지류와 본류의 합류의 혼합 현상을 규명하는 인자로 유속과 수심 등 기본적인 수리학적 인자들 외에 최근 하천 유사측정을 위해 부유사농도의 지표로 연구되고 있는 ADCP의 초음파산란도를 활용하여 합류부에서 상이한 유사특성을 가진 두 수체가 혼합되는 양상을 측정하여 합류부의 혼합 특성을 해석하고자 하였다. 초음파산란도는 부유사와 관련되는 인자로 SonTek ADCP 이동식으로 측정된 초음파산란도(SNR)자료를 빔퍼짐에 대한 보정, 물에 의한 흡수를 고려하여 보정한 후 3차원 혼합거동의 공간적인 분포를 도출하였다. 그리고 측정기간 중 드론(UAV), LISST를 이용하여 합류부의 혼합양상을 모니터링하여 초음파산란도를 이용한 분석결과와 비교하였다. 분석결과, ADCP로부터 제공되는 초음파산란도를 보정한 결과 합류부의 3차원적인 유사 혼합의 공간적 특성을 규명하는 데 적합한 인자라고 할 수 있었고, 상이한 본류와 지류의 유입을 고려하였을 때 다양한 혼합 거동을 분석하는데 지표로 사용이 가능함을 확인할 수 있었다. 따라서 본 연구에서는 남강과 낙동강의 합류부에 대해 초음파산란도를 활용하여 합류부의 혼합 특성을 분석하였다.

The purpose of this study is to reviews the Chinesm expressed in the modern fashion world after the year 2000, and underlines the characteristics of Chinesm, as the Chinese fashion market is getting bigger and becomes the cynosure of the world. The method of this study is by research on precedence as well as related researches in Korean and foreign books. The results were as follows. First, the Chinesm recreates the historic motive which is the traditional costume, ornaments, or make-up etc. to maintain the harmony between the modernity and the past, preventing from following or mimicking. Second, the Chinesm expresses the combinational and harmonious manner with the combined image on the Chinese original symbolic factors mixing with the foreign spatial-temporal elements, the various styles of wear and decoration, and the different images to have the natural or equivocal relationship with one another. Third, The Chinesm magnifies the feminine atmosphere to express the sensual image by using effectively the traditional design factors, which is tight silhouette, coverture, and exposure. Fourth, the Chinesm professes the pro-naturalism embracing the human without conflicting with the human nature. It seems possible on the new value mixed with colors, materials, or patterns, etc.

The purpose of this study is to understand the concept of a sexual image and verify the method of its design expression through case studies of the sexual image evening dress shown in an Haute Couture Collection over the last 10 years (2005~2014). The results of analysis are as follows: First, "expression by the seeing through of the natural body" expressed a natural sexual image that combined fashion of the previous times with the beauty of the natural body by using a see-through material and classic or ethnic image. Second, "expression of a sexual-image look that emphasizes romantic detail" illustrated a romantic sexual image that emphasizes feminine sensitivity by mixing various ornamental elements such as see-through material and symbolism of underwear image. Third, "creation of a nude look using skin color" expressed sexual image of an evening dress by inducing erotic sexual association through a combination of opaque material of skin color and design shape that is intended for body exposure. Fourth, "combination of sexual symbol and heterogeneous elements" expressed a decadent, avant-garde and futuristic sexual images by using women's underwear and a sexual symbol as design motif and mixed with mismatching elements. Fifth, "use of a fantastic black image" expressed an exclusive and refined sexual image and a decadent and primitive sexual image by using a fantastic image of black color. The results of this study are expected to be used for the design process of the evening-dress industry that aims for quality improvement.

This study attempted to investigate the perspective of the skirts of male and female students by analyzing the differences in image evaluation according to the constituent elements (type, length, and wearing method) of men's skirt designs in modern fashion. The study included 109 male and female college students from Generation Z residing or whose life center was in Gwangju Metropolitan City, to evaluate 12 images depicting types of men's skirts. First, the constituent image evaluation factors according to the constituent design elements of men's skirts were analyzed. Second, the differences in each constituent image evaluation factor based on the constituent design elements of men's skirt designs were analyzed. Third, the gender-based differences in image evaluation by men and women concerning the constituent design elements of men's skirt designs were analyzed. The analysis included relatively more women than men. The results of the image recognition dimension included the following categories: "attractive image," "evaluable image," "gender image," and "personality image." In modern fashion, skirts are used to express the diverse personalities of men's fashion. Thus, they are used beyond the stereotype of women's clothing, toward expanding and diversifying the image of men's clothing through mixing and creating a dichotomous image of men and women. It can be used as a design that suggests a gender-fluid image.

This study is on the esthetic characteristics in the haute couture work of Chanel. It first reviews the lives and the fashion philosophy of Chanel, a senior designer and Lagerfeld as representatives of the maison, from the haute couture collection since 2000. The results of the study are the following. First, reinterpreting the tradition, Chanel reproduced historical dress items or silhouette with modern sense, or she created a new modern Chanel image through her original restructuring and dismantling. Second, Chanel expressed balanced beauty of compounded eclecticism by accord between simplicity and ornamentation, which meant her design showed impartial beauty with simple silhouette, decoration with colors, accessories, and ornaments. Third, Chanel did not divide the value between men and women, and instead expressed androgyny through dismantling each gender's characteristics by borrowing or mixing. As a result, she emphasized the female image or created a new style through expressing symbolic image embracing masculinity.
