This paper focuses on Wajiro Kon (1888-1973) and his architectural efforts on theorizing Korean minka in the early 1920s. Wajiro Kon's unique phenomenological approach, so different from the positivistic analyses of his contemporaries, evident in his meticulous sketches and vivid descriptions, helped him theorize how the craft-oriented architectural development of Korean minka were shaped by people's everyday lives. In particular, he found that ondol had developed in various and complex ways, creating differences between the northern and southern Korean regions. Moreover, Kon identified the practical improvements in Korean minka made by inventive, creative people. However, the paper demonstrates that in this process, the new understanding retained the dual perspective of Korean minka as not only environmentally formulated, craft-oriented artifacts but also as re-formed objects that should be improved through an interplay with external factors.

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.

Architectural style is said to be product reflecting political, social and cultural condition. Especially, in colony, architectural style is strongly related to political condition or policy. After colonization in 1910, public buildings with western historical architectural style in Japanese version were widely built by Japanese colonial government in Korea. And in the late 1920s, modernism style in architecture became dominant in Korea as like other countries. In this situation, curious buildings in strange architectural styles came out. One example is railroad station buildings with traditional Korean architectural style and timber house station having a steep roof which is widely used in North Europe such as Alps area with good sights and mountains. Generally, the colonizer says that colonization is the only way to save the colony at crisis defined by colonizer and they insist that they can help the colony modernize. To justify colonization, the colonizer attributes the colonization to the characteristics of the nation and stagnation of the traditional culture etc.. Accordingly, the colonizer tries to depreciate colony's traditional value and culture. In case of colony which has similar cultural background historically (in this case, economical exploitation is less important than other Asian colony by European power), this depreciation of traditional value and culture in Korea was done more strongly than others. At this time, we should understand special relation between Korea and Japan historically. Even though, colony's locality is adopted by the colonizer in public fields, which is based on political purpose or exotic taste etc.. In early days of Japanese ruling period, Japan never use the Korean traditional facts in public. Therefore there is no use of Korean traditional architectural style in public field. In late 1920s, some railroad station buildings were constructed in new styles without precedence in modern Korea. One is railroad station buildings in Korean traditional architectural style, the other is railroad station buildings in timber house stations having a steep roof which is different form western historical architectural style. It was mystery that Japan had constructed railroad stations in Korean traditional style which Japan had tried to destroy together with Western style railroad station buildings. This paper is made to solve the mystery why the colonizer(Japan) constructed entirely different types of railroad stations at the same time in the late 1920s and 1930s. The key point to solve this mystery is tourism. In this paper, to solve this mystery, I try to use terminology' 'Colonial Tourism' in architecture why colonial power had constructed railroad stations with colony's traditional architectural style and Western style having a steep roof which can be seen north European region.

Various mathematical models have been widely studied recently in both fields of mathematics and ecology since they help us understand the dynamical process of population changes in biological species living in a certain habitat and give useful predictions. The world population model proposed by Malthus, a British economist, in his work 'An Essay on the Principle of Population' published in the period of 1789~1826 is one of the early mathematical models on population changes. Malthus' models and the carrying capacity models of Verhulst in 1845 were based on exponential type functions. The independent research field of mathematical ecology has been started from Lotka's works in 1920's. Since then various different mathematical models has been proposed and examined. This article mainly deals with single species population change models expressed in terms of ordinary differential equations.

This research is aimed at identifying the perception associated with urban regeneration and predicting policy implications of future directions by analyzing the trend of urban regeneration depicted in the mass media by utilizing SNA (Semantic-Network Analysis) techniques. As the number of articles has increased, it is noted through analysis that the interrelationships between social phenomena and issues have combined to form the meaning of urban regeneration. Overall, 'urban' and 'regeneration' keywords also appeared at different periods, with 'urban' closely related to 'regeneration' starting in 1970 when urbanization was becoming more prevalent. It was analyzed that the frequency of 'urban' appeared more frequently in the early 1990s, while the frequency of 'rural' decreased sharply. Until the 1990s, the slums and the recession that appeared as side effects of urban problem-solving policies were mostly concentrated in cities. Policy discussions were conducted with the goal of improving the physical environment of cities rather than concentrating on the surrounding rural areas. The distributions of the keywords 'development' and 'regeneration' have increased quantitatively since the 1970s, and urban polarization has exploded due to the development of the external growth of cities, mirroring the trend of accelerated environmental threats. In particular, the keywords for 'regeneration' emerged mainly related to environmental problems, which led to the need for urban regeneration, and environmentally and ecologically friendly development. The emergence of "urban," "regeneration" and "environment" as keywords having to do with urban regeneration grew in the 1990s. This suggests that urban regeneration is now linked to "environment", as that has become a social issue.

This paper, based on "Minhwa Chaekgeori" paintings from the collection of the National Museum of Korea, identifies and discusses fourteen similar works in domestic and international collections as products of the Seokdang workshop. First, the relevant paintings are identified as products of the workshop known as Seokdang (石堂, literally "stone hall") by the workshop's seal that is stamped on them. Second, analysis of the iconography indicates that the paintings were likely produced in the 1920s. Third, research on certain geographic names and addresses associated with this group of paintings suggests that they might not have been separately commissioned, but are rather examples of partially "ready-made" paintings. Fourth, the paper discusses how the designs of various cultural products in these paintings reflects contemporaneous changes in Korea's diplomatic and commercial relations, i.e., the decline of relations with China and rise of relations with the United States and Europe. Finally, a comparison of the Seokdang chaekgeori paintings with the popular chaekgeori paintings produced by Yi Hyeongrok and Yi Deokyeong in the early twentieth century provides important implications for the succession of tradition and innovation in visual culture.

This study analyzes how Princess Deokhye's photos before entering elementary school were exploited in newspapers during the Japanese colonial period by introducing Roland Barthes' semiological methodology for analysis of photography. In the early 1920s, the Japanese imperialists actively exploited Princess Deokhye, who was about to enter elementary school, to propagate their education policy. The Maeil Shinbo cooperated with their policies by publishing photos and articles of Princess Deokhye. In this paper, 2 photos and articles published in Maeilshinbo were analyzed. As a result, it was found that messages were produced that justified Japanese education policy by using various rhetorical techniques of photography and texts complementary to each other, and that the readers were induced to accept them naturally. In conclusion, it was possible to reveal the seriousness of the problem in that these articles were not merely for propaganda of policy, but were to encourage the disappearance of the traditional values of Joseon.

The professional alliance between disciplines of architecture and furniture design in the interwar years as displayed in the prominent architectural exhibitions of the era is interesting in the context of professionalization of American architecture. The way furniture design gradually became part of the architectural shows not only reflected but provided the practical field in which the architectural institution sought, under the new social order since the mid 1910s, a new professional cast-departing from the former milieu in the realm of high-art by the Beaux-Arts Movement. Exhibitions held by the Architectural League of New York in the 1920s revealed that the early impetus for reformation toward efficiency had been subsumed by the system of Beaux-Arts. By contrast, "The Architect and the Industrial Arts" show of the Metropolitan Museum of Art, in which the most prominent architects of the era exercised their professional expertise in the design of "Moderne Style" interior furnishings, clearly shows how architects, in the milieu of expanding commercial market, sought to align their profession as industrial designers.

The purpose of this study is to establish the relationship between Durand's architectural theory which provided reasonable architectural logic in the early 19th century, and architectural logic of the Modern Movement of Architecture led by avant-garde architects in the 1920's. The system of thought in architecture proposed by Durand which clarified a architectural design method(composition) is very similar to the one of the International Style(Book), which summarizes commonalities in the flow of modern architecture. This approach has something in common from the perspective of the systems of thought, despite differences in external forms and time gaps. Therefore, this study intends to examine the systems of thought in three ways. It is to examine how the two systems of thought define architecture, what is the logic of building production, and finally the value of architecture (including aesthetic values) while eliminating classical aesthetics.
