Air cleaners in all of the automotive engines have been used for decades. In the early 1920's the oil bath type was the popular shape of air cleaners. The air cleaners of the oil wetted bath type were introduced in 1940's. The shape of the dry pleated paper type media was introduced in the 1950's. This trend still continues with new and innovative media being introduced. Engine air cleaners should have effectively removed and reduced harmful contaminants being ingested into engines. This studies show that both, the ingested contaminant size and concentration need to be controlled. This paper com pare and analyze the characteristics over the economics, engine performances and reduction of noises of power-plus air filters with wet paper which were sticked to heavy duty diesel engine.

Lee Sang, one of the representative poets of Korean Modern Poetry, wrote poems which present the existentialistic modernism in the 1920s, the chaotic era of Korean history. The characteristics of his works have been shown by various points of view. This paper especially explored the meaning and feature of mathematical expressions by numbers, symbols and other signs of mathematics in Lee's poems. His poems are composed by scientific and abstract rules in mathematics which are expressed as mathematical symbols. The paper focuses on analyzing seven poems which maximizes mathematical expressions among his poetry. This kind of work would be the one of ways to figure out the features of mathematics through literature.

This paper examines the service ideal preached by Bruce Barton, a bestselling American author in the 1920s. Based on archival sources and other historical materials, this paper presents Barton's endorsement of service ideal less as an adaptation to the looming consumerist society than an endeavor to revive the old producer ethos that was more coercive than therapeutic. Revisiting Barton's messages to Americans, this paper traces the intellectual root of Barton's service ideal to the Social Gospel and illustrates the ways his producer ethos evolved into a commonplace ideology of Christian meritocracy that endorsed individualism and small government.

In terms of modern design history, De Stijl movement had continued as one of influential groups by 1931, and it attempted to pursue universial reality that combined painting and architecture, seeking a new style based on Neo-Plasticism and succeeded the nineteen century's Art and Craft movement and Art Nouveau. Especially, the De Stijl movement provided 1920's rationalism with new space pattern and its ideas greatly affected the Bauhaus movement such as Walter Gropius or Mies van der Rohe. De Stijl's utopian idea that claimed on the conformity of art and life contributed modernism movement combined with scientific and rational view, and even now experts its lasting power with the concept of time and space free from simple cube in modern architecture and interior design. The tue meaning of the De Stijl movements is that is sis the basis of general ideas, and the change of modern architecture is based on this modern styled foundation. It may be the unchangeable fact like Russell Hitchocok says, "The architectural style and pattern which everyone admitts its importance has the value of living."

Peking has peculiar features as capital city, and has gone through various transformations, with its name changed from Peking to Peiping to Peking. Even when it did not serve as a capital city, it still played an unrivaled role in cultural aspects. Laoshe, a great writer of 'Peking flavour' literature, is famous for works full of cultural charms of Peking. In his works, which show the manners, norms, art, culture and optimistic life style of Peking, Peking culture is described as an extension of cultural traditions of Qiren. In addition, his critical view of reality is also expressed in the works. Linhaiyin's literary works show ordinary hutongs she experienced in the 1920s in Chengnan, the southern part of Peking, and the quiet and simple life of warm-hearted people living there. Her vague memories of Peking, along with her nostalgia for the city, let her describe the city with recreated happy memories of it instead of the harsh critical view. Her works express the city in her recreated memory full of hope, with her dark memories of the city being glossed over. As seen above, Laoshe realistically described the tragic and difficult life of low class people in hutongs of Peking as well as lower middle class people of the city. Meanwhile, in ChengnanJiushi, Linhaiyin expresses the daily routine and ordinary life of people in Peking from the perspective of middle class people. In addition, she showed the sympathetic view of middle class citizens towards their low-class neighbors. In Peking Menghualu, Wangdewei mentioned that the 'castle of memory' which old Peking people in Taiwan tried to establish fills an important gap for the continuity of Peking cultural history and cultural imagination. This indicates that the 'Peking castle of memories,' which Linhaiyin, a Taiwanese writer well known for 'Peking flavour,' has established plays a big role in filling part of such gap. ChengnanJiushi, Wuyigong's film based on Linhaiyin's novel of the same title, also describes the daily sceneries and culture of the southern Peking in the 1920s, which both Taiwanese and Chinese people miss, through sophisticated images with 'profound yearning tinted with calm sadness', accomplishing an artistic achievement different from that of the novel.

This study analyzed domestic media articles from 1920 to 2017 using R 3.4, a big data analysis tool. In addition, it examines the sexual minority discourse reproduced through the media for about 100 years, focused on the role of the film as an art of struggling with the projective aversion to sexual minorities. sexual minorities in movies are not abominable. They are people we already know in our daily lives, and they are just different in sexual orientation. In general, sexual minorities are less likely to encounter in everyday life, so they are experienced and perceived through what the media present. It is noteworthy that the representation of sexual minorities in the media is formed as a major agenda of our society by publicizing the problems underlying society on the surface. It causes social issues to be raised by revealing and highlighting the problems that are regarded as alienated and avoided from the mainstream's gaze. The content provided by the media enables a three-dimensional experience of subjects who have not experienced it by themselves, and has a decisive influence in correctly recognizing and judging society. Media content suggests that it can be a powerful weapon of recognition struggle that can naturally fight against social hatred without using methods such as demonstrations or protests.

The purpose of this paper is to study on colonial modernity of commercial space in the case of commercial companies in Kyungsung(Seoul) during Japanese colonial period. Commercial companies in Bonjung2jungmok had the greatest growth in the numbers and the scale of company's capital from 1920s to 1930s. Japanese's commercial companies had concentrated in Bonjung1jungmok and the scale of Japanese's capital had been the greatest in Hwanggumjung2jungmok. Korean merchants had tried to change their commercial organization to modern and capitalistic system in the face of infiltration of Japanese merchant capital in Kyungsung. They had established some modern stock companies and had managed a few companies of large capital such as Hwasbinyeonshejum(a multiple shop) in Jongro2jungmok. We may observe the modernity of commercial companies in some modern stock commercial companies and the activities of commercial merchants in Kyungsung. But Korean's commercial companies had been small-scale businesses in comparison with Japanese's commercial companies. Colonialism in commercial space in Kyungsung had been appeared doubly in ethnical segregation of commercial activities and the scale of commercial capital.

Damaged the Jeoguibon (patterns of the Queen's ceremonial robe) was found during repair work of Daejojeon, Changdeok Palace in 2011. Analytical study on seven colors painted in the patterns has been conducted by P-XRF and Micro-XRD analysis. The result displays that red lead, ultramarine blue, conichalcite or mixed pigment of emerald green and barium white, orpiment and white lead had been used on the patterns. Comparison of the pigments used for the Pyeseulbon (patterns of the Queen's belt ornament covering knees in the front) housed in National Museum of Korea has revealed that not only red lead but also cinnabar and organic pigment had been used in the Jeoguibon and the Pyeseulbon housed in National Museum of Korea. In addition the same pigments has been examined in green and yellow parts of both the Jeoguibon in Daejojeon and the Pyeseulbon housed in National Museum of Korea. The result has shown that western's synthetic green pigment such as emerald green was introduced and used in 1920's. The scientific result from this study expects to be used as useful referencing data for the comparative understanding on pigments used in palace during the 20th century.
