The distance between livestock facilities and residential spaces is decreasing. Moreover, livestock odor complaints are increasing due to the large-scale and concentrated livestock breading industry. In order to reduce odor from livestock facilities, bio-curtain that are easy to install and inexpensive are commonly used in Korea. However, there is a lack of basic data on design standards and operation manuals for bio-curtains. The installation density of the bio-curtain material is an important factor that affects the odor reduction rate, increment of the load on the ventilation fans, and the structural stability of the curtain. There are limitations on deriving the design conditions of the bio-curtain by only field experiments targeting invisible air. Therefore, aerodynamic simulation such as CFD (computational fluid dynamics) can be used to obtain quantitative data according to various environmental conditions. Bio-curtain is a porous medium with a complex structure, and it is necessary to derive aerodynamic coefficients to analyze it. In this study, the wind speed and pressure difference according to the design density of the bio-curtain were monitored using the experimental chamber. Using the field results, a pressure resistance curve was created for each flow velocity and installation density. The viscosity and resistance coefficient of the bio-curtain were calculated through the derived resistance curve. .

This study aims to examine the tendency of Paintings in Korea during the Japanese occupation period through the various aspects of Oh Chiho’s portrait paintings, and to find out how one artist builds his own art world under such circumstances. In Oh Chiho’s paintings, three styles of painting and his geographic and temporal transfigurations were found: Firstly, the academic realism, learned and practiced from an Art school, secondly social realism, finally the Modernism. His ‘Charcoal Dessin based’ Nude is a academic figure painting. Country Little Girl is not an example of academism or a pure art work, but a participatory work set in the context of the times around 1930. After the fail of anti Japanese cultural movement, Oh Chiho found the colorist Van Gogh who can be said to have influenced on the work of Oh Chiho. He painted Portrait of Painters wife in modern style. 이 연구는 오지호의 인물화의 변화과정을 통해서, 일제 강점기라는 시대적 상황 아래에서 한 작가는 어떻게 자신의 예술세계를 구축해 나가는 가를 알아보기 위한 것이었다. 오지호의 인물화들에서 미술의 세 가지 양식과 그 지리적, 시대적 변용(變容)을 찾을 수 있었다. 미술학교에서 배우고 익힌 아카데미적 사실주의와 사회적 사실주의, 미술 그 자체만이 목적일 수 있는 모더니즘 양식이다. <누드>는 목탄 데생이 기초가 되는 아카데미즘의 인물화이고, <시골소녀>가 아카데미즘이나 순수미술작품이 아니라 1930년을 전후한 시대적 상황을 배경으로 한 현실참여적 작품이다. 계몽적 문화운동이 끝난 후, 오지호가 만난 색채주의자 반 고흐는 오지호의 작품이 모더니즘으로 가는데 영향을 주었다고 할 수 있고, 1937년 <처의 상>은 모더니즘적 인물화라고 할 수있다.

다다와 초현실주의

오병욱 圓光大學校 1996 論文集 Vol.32 No.2

New artistic movements in the beginning of this century did destruct out completely academic arts and erecting new style tradition. So called Avant-Garde art, in this style artist must be a forerunner and artistic works must encounter the future, not past nor present. So this Avant-garde art challenge unceasingly against the tradition to get new possibility. Cubism, Dadaism and Surrealism were the mainstream of this avant-garde. These styles had destruct tradition in different ways ; cubism destruct the formal aspect of traditional arts by experimental works, dadaism refused totally its tradition and surrealism broke it by exploring subconsciousness. This these is focused on dadaim and surrealism ; its beginning, development and characteristics in style. Dada was the movement of literatures and fine arts during 1915-1922, the nature of which was nihilism and destruction. It was deployed in Zurich, New York, Berlin, Paris etc. It's character was differentiated belong its native cities. Zurich, the center of Dada movement during the World War II, had a group of artists refugee of the war. They accused a crisis of the moral, political and culture by means of irony, provocation and hazard. In New York, out of the battle field, Dada was introduced by European artists. So its Dada had a character less aggressive and more conceptional on the arts ideas. They questioned on problems which concern on the nature of fine-arts, role of artists, etc. Berlin Dada had a very serious character, because Germany had defeated of the war in October, apparition of communists in December of the year 1918. Dada was a revolution for them, and it had political purposes. They expressed hopeless situation, fury, madness, death etc., mostly destructive anywhere else. After the end of the war Dada was accepted in Paris. Paris Dada succeeded Zurich's ironic, nihilistic spirit. They challenged against traditional concepts arts, accused bourgeoisie. They refused wars, morals, tastes and conventions superficial. Spirit resistant of Paris Dada was succeeded to surrealism. Ex-Dadaists Breton et Eluard had published in 1924 manifestation surrealists. They pursuited automatism of thinking, out of reason and prejudices for reaching in the ultimate truth. They used mainly power of imagination for the purpose of recovering true language, seeking for possibilities of subconsciousness world, and discovering a concord of reality and imagination. Surrealism movement could be divided in two period ; first one is period of automatism, Masson, Tanguy, Miro, Ernst worked with spontaneity fulfilled imagination. Second one is pursued by Dali, Magritte, they expressed fantastic images of dreams in realistic painting. Surrealists liberated and modified subconsciousness, representing the world more wide.

It has already been four years as of 2013 since the Departmentalized Classroom System was first introduced following the Korean government's policy. However, no investigation had been made yet on whether the system is properly being managed in practice according to the presented standards, guidelines, and policy direction. Hence, an in-depth investigation and analysis were called for. In line with this, documents were researched, deliberation meetings of experts were held, and the system pilot was tested to develop indices to investigate the state of block-scheduled classes and classes for each student's academic level for the educational classes field. For the school management field, we developed indices to investigate the teachers' organization and their division of labor, administrative officers and work reduction, improvement of teachers' expertise, and the guidance of the students' school life. Based on the indices, we investigated the state of 24 schools, which manage an advanced school system, nationwide. The results showed that the Departmentalized Classroom System has now reached the settling stage, which is beyond the introductory stage, and that it needs to be systematically supplemented for it to be settled in a stable manner.

Metal Face 기법을 이용한 인테리어 장식 타일에 관한 연구

오병욱 한국공예학회 2001 조형디자인연구 Vol.4 No.2

The interior which used to be viewed as one of the luxurious privileges of the upper class is expanding its world, even marking its territory in simple and humble homes, thanks to the heightened standard of living today. It has been man's innermost and eternal desire to decorate the space he belongs to. The perception of a house no longer involves the simple concept of possession, but the very instrument has taken its place to be decorated for the resident's expression of his or her personality. Art works including industrial arts have made their valuable contribution to the rise of interior since the beginning of it. The real value of art works reaches its highest point when they are among everyday living. This means art works should make an appropriate harmony with all the constituents of the interior, transcending the artistic feature they have as pure art. In particular, industrial arts have a clear distinction compared with paintings and sculpture. Sure they don't deliver big logics or messages, but they sure can avail themselves as a constituent of the interior with the most familiarity to it. Decorative tiles manufactured in the metal face technique is made of polyester which is economical and practical and has the surface treated to yield the handcraft metal-like effect. With this process, the tiles transform themselves into a whole new level of image with natural touch and feeling. The simple metal color will have the patination effect with coloration. The chemicals covering the sawdust grains will corrode and react in a still and smooth way, and then the colors of green, blue, orange red, and brown shall yield the pastel effect. Thus, tiles produced in the metal face technique will shed off the general cold and strong image of metal and be reborn as artwork tiles with warm and human space, thus presenting themselves as the best candidate to create a brand new image of the interior.

한국적 미에 대한 오해 -류종열, 고유섭, 윤희순의 논고 비교분석-

Art theorists support art productions by, introducing them to the public, explaining their meanings, and playing a crucial part in the development of art. These tasks seem like their opus. Because the principles of art production and the artistic languages are quite different from the ordinaries, we need 'interpreters' who can mediate us and the artists. Art works need interpretation. And the interpretation includes not only the characteristics of the given art work, but the customs, history, and the unique qualities of the race that produced the art work. The former director of the Korean National Museum, Choi Soon-woo wrote on the characteristics of Korean art as those that stem from the poised, arbitrary, and non-elaborate state of mind. The statement of the former Director of the National Museum has its weight far greater than just a personal opinion. In fact, we encounter the same resonance of this statement over and over reproduced in the mass media. The problem lies on that it deals with not only a single art work, but the entire Korean art. And going further, this kind of remarks are already infused into every sector of our thought on art appreciation. In this paper, I argue for a re-reading of the characteristics of Korean beauty based on two reasons. First, the characteristic of art work is contemporary, thus we cannot define the characteristics of entire Korean art in a few words without the context of the period of its making. Second, Director Choi defined the characteristics that I pointed out above as 'natural' and 'nature-friendly.' Nature or being natural is not an usual word that defines the characteristics of art work, which stands for the opposite side of the nature in the binary opposition of nature/culture. To delve into these misunderstandings of Korean beauty in the popular notions of Korean art, I suggest the re-reading of three major articles on Korean art: Ryoo Jong-yeol's "Korean race and its art," Ko You-seup's reiteration of Ryoo's thesis called "Discourses in Korean Art History and Aesthetics," and Yoon Hee-soon's antithesis of Ryoo Jong-yeol titiled "Studies on Korean Art History."

The internal environment in pig house is closely related to the animal productivity. In addition, it is important to consider a working environment insidethe pig house due to high gas and dust concentrations. The poor working environment inside the pig house can cause health problems includingrespiratory diseases. To analyze the working environment, it is important to evaluate the ventilation efficiency to effectively remove harmful gases anddust. The purpose of this study is to develop a 3D CFD model to analyze the working environment in the pig house. CFD model was validated bycomparing air temperature distributions between CFD computed and field measured data. The average air flow rate at the pig height was 40.1 % lowerthan the working height when incoming air was concentrated on upper layer by the installed ventilation system on the experimental pig house. Usingthe validated CFD model, the regional ventilation efficiency was computed by the TGD(tracer gas decay) method at the pig and working heights. Therewas a difference of ventilation efficiency on 14 % between the air stagnated section and the rest sections. Stagnated gas concentration can be effectedby animal and human health.
