As the range of the customer choice becomes more diverse, the average life span of companies' products and services is becoming shorter. Most companies are striving to maximize the revenue by understanding the customer's needs and providing customized products and services. However, companies had to bear a significant burden, in terms of the time and cost involved in the process of determining each individual customer's needs. Therefore, an alternative method is employed that involves grouping the customers into different categories based on certain criteria and establishing a marketing strategy tailored for each group. In this way, customer segmentation and customer clustering are performed using demographic information and behavioral information. Demographic information included sex, age, income level, and etc., while behavioral information was usually identified indirectly through customers' purchase history and search history. However, there is a limitation regarding companies' customer behavioral information, because the information is usually obtained through the limited data provided by a customer on a company's website. This is because the pattern indicated when a customer accesses a particular site might not be representative of the general tendency of that customer. Therefore, in this study, rather than the pattern indicated through a particular site, a customer's interest is identified using that customer's access record pertaining to external news. Hence, by utilizing this method, we proposed a methodology to perform customer segmentation. In addition, by extracting the main issues through a topic analysis covering approximately 3,000 Internet news articles, the actual experiment applying customer segmentation is performed and the applicability of the proposed methodology is analyzed.

Shake table testing has been regarded as one of the most effective experimental approaches to evaluate seismic response of structural systems subjected to earthquakes. However, reproducing a prescribed acceleration time history precisely over the frequency of interest is challenging because shake table test systems are eventually nonlinear by nature. In addition, interaction between the table and specimen could affect the control accuracy of shake table testing significantly. Various novel control algorithms have been proposed to improve the control accuracy of shake table testing; however, reference values for control performance assessment remain rare. In this study, reference values for control performance assessment of shake table testing are specified based on the statistical analyses of 1,209 experimental data provided by the Seismic Simulator Laboratory of National Center for Research on Earthquake Engineering in Taiwan. Three individual reference values are considered for the assessment including the root-mean-square error of the achieved acceleration time history; the percentage of the spectral acceleration that exceeds the determined tolerance range over the frequency of interest; and the error-ratio of the achieved peak ground acceleration. Quartiles of the real experimental data in terms of the three objective variables are obtained, providing users with solid and simple references to evaluate the control performance of shake table testing. Finally, a set of experimental data of a newly developed control framework implementation for uni-axial shake tables are used as an application example to demonstrate the significant improvement of control accuracy according to the reference values provided in this study.

Main theme of this paper is the evaluation of the historical significance of Luciano Baldessari's exhibition works mainly during the Fifties. In order to understand the formal and logical basis of those project, his relationship with the historical Avant-gardes and the consequences expressed in his pavilion projects for the Breda Industrial Company are analyzed. The first part focuses on the influence of Italian Futurism, German Expressionism and Italian Rationalism on the formation and experience of Baldessari during the interwar years. The encounter with these movements determine the interest but also the principles along which Baldessari represents his idea of object, space and place. Specially his professional activities during Fascism would determine his attitude toward political power and the necessity of autonomy in artistic sphere. In the second part, different themes that Baldessari affronted in each project of Breda Pavilions is analyzed. Another important issue regard the historiography of the contemporary architecture. Often, many important works that lies in the threshold of the disciplines such as painting and sculpture and media art were excluded in the history of architecture just because they do not deal with the architectural object. Recently, many elements such as theatrical project and temporary objects are considered as part of urban reality and architecture with acknowledgment of their capacity to create event and situations. Along this thought, not just the reconfiguration on the territory of architecture in present but also the criterion to evaluate the past history of architecture is changing drastically. This study on the pavilions of Baldessari intends to contribute indirectly on the current issue of dominion of architecture, but also to evaluate objectively recent architecture. Consequently, architectural protagonists such as Baldessari and their ephemeral projects would be evaluated compressively in their multiplicity of significance.

Our investigation of the intricate relationship among nationalism, humanism, and imperialism begins from reading Song of Ariran, the auto/biography of Kim San recorded by Nym Wales, together with Margaret Drabble's fictional adaptation of Lady Hong's autobiography, The Memoirs of Lady $Hyegy{\breve{o}}ng$, in her novel The Red Queen, in which the story of Barbara Halliwell, a modern female envoy of Lady Hong, is interweaved with Lady Hong's narrative. In spite of their being seemingly disparate texts, Song of Ariran and The Red Queen are comparable: they are written by Western female writers who deal with Koreans, along with the Korean history and culture. Accordingly, both works cut across the boundary of fiction and fact, imagination and history, and the East and the West. In the age of globalization, Western women writing (about) Korea and Koreans traversing the historical and cultural limits inevitably engage us in post-colonial discussions. Despite the temporal differences--If Song of Ariran handles with the historical turmoils of the 1930s Asia, mostly surrounding Kim San's activities as a nationalist, The Red Queen is written by a twenty-first century British woman writer whose international interest grapples with the eighteenth-century Korean Crown Princess' spirit in order to reinscribe a story of Korean woman's within the contemporary culture--, both works appeal to the humanistic perspective, advocating the universal human beings' values transcending the historical and national limitations. While this sort of humanistic approach can provide sympathy transcending time and space, this 'idealistic' process can be problematic because the Western writers's appropriation of Korean culture and its history can easily reduce its particularities to comprehensive generalization, without giving proper names to the Korean history and culture. Nonetheless, the Western female writers' attempt to find a place of 'contact' is valuable since it opens a possibility of having meaningful communications between minor culture and dominating culture. Yet, these female writers do not seem to absolutely cross the border of race, gender, and culture, which leaves us to realize how difficult it is to reach a genuine understanding with what is different from mine even in these 'universal' narratives.

This study is to discuss the content of Posangkimun on the whole and to report the understanding of Seokgok Lee Gyujoon on western civilization. Through the overall analysis of Posangkimun, it is found the following facts: 1. Posangkimun aroused interest of academic circles as it covered theories of western civilization. Most of the introduction to western civilization contained in the book is related to astronomy and geography. Seokgok criticized all the western theories on revolution of the earth, astronomy, continents and oceans on the ground that these theories were not congruous with the teaching of the Oriental sages. 2. Seokgok found the reasons why the West had led the East from 'nationalism' of the West. The nationalism mentioned here were more similar to 'democracy' in modern sense, or rather 'democratism'. What is specially noteworthy is that he did not find the reasons of western advancement from the spiritual issues not from the machine civilization. In this way, Seokgok could avoid the fallacy of throwing away traditional ideas to concentrate in western machine civilization. 3. The content of Posangkimun shows that Seokgok was a person with a very conservative view. Notwithstanding his inclination, he had good knowledge about western theories, most of which were gathered from newspapers and magazines at that time. It means that newspapers and magazines should be treated with more importance when studying Korean intellectuals in late Joseon period or during the time of Japanese forced occupation.

최근, 유명 연예인과 인사들의 우리나라 위인에 대한 망언과 실언이 방송에 나감으로써 국민들에게 질타를 받는 안 좋은 이슈를 일으켰다. 반면에, 유명 예능 프로그램에서 특집 편성한 일련의 방송으로 인해 국민들의 역사의식이 높아지고 있다. 이렇게 국민들이 우리나라 역사에 대한 생각이 깊어졌을 때 반드시 짚고 넘어가야 할 점은 바로 역사의 사실성이다. 매체에는 '몰입'이라는 강력한 힘이 존재하기 때문에 수용자 즉, 플레이어가 그 게임에 흥미만 갖게 하는 것이 중요하다. 따라서 역사 사실을 바탕으로 제작된 게임들이 플레이어의 흥미 유발과 관심을 끌기 위해 또는 게임과 캐릭터의 특징을 만들기 위해 역사적 사실과 맞지 않게 제작하는 상황이 발생한다. 그래서 본 연구자는 플레이어들이 올바른 역사의식을 가질 수 있도록 역사 사실을 바탕으로 제작된 'HQ team'사에서 개발한 '천년의 신화'라는 게임을 선정해서 게임 속에 등장하는 '광개토대왕', '근초고왕', '무열왕'의 디자인과 역사적 사실을 비교 분석하고자 한다. 그 결과 역사적인 사실과 게임 속 캐릭터의 디자인이 일치하지 않는 것으로 나타났다.
