  • In order to correct the provided RPC and DEM generated from the high-resolution satellite images, the acquisition of the ground control point (GCP) must be preceded. This task is a very complicate that requires field surveys, GPS surveying, and image coordinate reading corresponding to GCPs. In addition, since it is difficult to set up and measure a GCP in areas where access is difficult or impossible (tidal flats, polar regions, volcanic regions, etc.), an alternative method is needed. In this paper, we propose a 3D surface matching technique using only the established ground coordinate package, avoiding the ground-image-location survey of the GCP to correct the DEM produced from WorldView-2 satellite images and the provided RPCs. The location data of the public control points were obtained from the National Geographic Information Institute website, and the DEM was corrected by performing 3D surface matching with this package. The accuracy of 3-axis translation and rotation obtained by the matching was evaluated using pre-measured GPS checkpoints. As a result, it was possible to obtain results within 2 m in the plane location and 1 m in height.

  • The Analog data is impossible to perfect reconstruct original data at a hologram data storage because of noise such as cross talk. So it is necessary that data can be stored by digital signal unavoidably. Therefore this work deals with experiments from this point of view through writing & reading of digital data. We stored 256bit digital data at one point on As-Ge-Se-S chalcogenide thin film and we reconstruct original data of 100% through the specified algorithm such as the histogram equalization, the interactive correction, etc. This result shows that the data is able to reconstruct under relative low diffraction efficiency. As the result, we expect the possibility of chalcogenide thin film for HDDS as the analysis of the effective resolution refer to reconstruction rate and diffraction efficiency.

  • This study would understand the overall perception of our society about public libraries, analyzing the texts related to public libraries, utilizing the semantic connection network & sentiment analysis. For this purpose, this study collected data from the last five years with keywords, 'Library' and 'Lifelong Learning Center' from January 1, 2016 through November 30, 2020 through the blogs and cafés of major domestic portal sites. With the collected data, text mining, centrality of keywords, network structure, structural equipotentiality, and sensitivity analyses were conducted. As a result of the analysis, First, 'reading' and 'book' were identified as representative keywords that form the social perception of public libraries. Second, it turned out that there were keywords related to the use of the library and the untact service due to the recent spread of COVID-19. Third, in seeking a plan for the development of public libraries through the keywords drawn to have positive meanings, it is necessary to create continuous services that can form a new image of the library, breaking away from the existing fixed role and image of the library and increase the convenience of use. Fourth, facilities and facilities for library services were recognized from a neutral point of view. Fifth, the spread of infectious diseases, social distancing, and temporary closure and closure of libraries are negatively related to public libraries, and awareness of librarians has been identified as negative keywords.

  • The purpose of this study was to derive the characteristics of fashion that appeared in the daily life of bourgeois women in Paris in the late 19th-century, and to examine the attitudes women showed toward fashion in the modernized city of Paris. The research method was a literature study and a visual data analysis study targeting fashion of bourgeois women from 1860s to 1900s out of Mary Cassatt's 155 works and Berthe Morisot's 147 works from Wikiart's digital images. The characteristics and attitudes showed in fashion in terms of women's painter's work, women's daily life, and women's space are as follows. First, while the subject matter of their works was restricted to the house, fashion was described with the sensual colors, elegance, and sophistication anticipated of a woman's nature. The represented attitude toward women and fashion includes advice for pursuing the dignity of maternal love and women's intellectual life, as well as an attempt to reflect a current point of view on the woman image. Second, the daily life of bourgeois women was childcare, needlework, reading, and grooming. They valued socialization and entertainment as well as intimacy and education with children, so they wore different clothes depending on the situation. This suggested that it was necessary to dress appropriately both at home and when going out. Third, despite the fact that the public space for women was limited, they dressed elegantly in a variety of trends when they went out. This was fashion worn only for appearance.

  • Autonomia movement that emerged in Italy in the 1960s from workerist (operaismo) communism gives historical and discursive context to Manfredo Tafuri's famous criticism of ideology. His thesis on the death of architecture was a radical criticism of Keynesian intervention which was a strategy to cope with the Great Depression. For him, this capitalist development had taken away ideological prefiguration from architecture. At least Tafuri's this early intellectual phase was formed in the wake of magazine Contrapiano and Antonio Negri's influence. Tafuri almost entirely adapted Negri's thought on the importance of capitalist innovation that was uncovered by Keynes, Schumpeter, and Manheim and the periodization in modern history. When we read Tafuri's text with this concrete context, we can avoid being plunged into his abstruseness. On the other hand, 1980's Korea cannot understand Tafuri comprehensibly. 1980's situation to struggle to acquire democracy prescribed only one mode of reception of Tafuri's historiography in Korea. Tafuri's so-called pessimist view point could not satisfy student activists. They want to take intellectual means to sustain student movement and to secure political dynamics of protest. But at the same time they have anxiety to understand tafuri's thesis that they consider ad a critical theory for Korean Architecture. Double contexts of Tafuri's criticism of ideology bring to light to historicize both Tafuri's historiography itself and reception of his text in Korea.

  • The purpose of this study is to re-read the film of Dead Poets Society, specially focused on a feminist view. The film hides the strategy of recovering the traditional Patriarchal Society. At the beginning, the film resists the values of traditional society through John Keating. His unorthodox methods of teaching literature smack against the traditions of Welton Academy. Furthermore, he stresses on "Carpe Diem"—Seize the Day, the romantic values of free thinking, creativity, and individuality. The forces opposing Keating's philosophy are personified by Welton's rigid, old headmaster, Mr. Nolan, and the cruel, stubborn parent, Mr. Perry. Keating's romantic values are failed by their powerful, dominating attitudes. Effected by Keating's philosophy, Neil decides to pursue acting rather than medicine. He conflicts with his strict father. Finally frustrated by his authority, Neil commits suicide. And Keating is accused of inciting the boys to restart the Dead Poets Society, and at last he is fired. Keating and Neil are victimized by the Patriarchal society. Even though the film concentrates male characters at the all boys' school, it reveals the male angle of binary oppositions between men and women, subject and object, activity and passivity, presence and absence. In the film's dramatic conclusion, English class is now being temporarily taught by Nolan, who has the boys read from the very Pritchard essay they had ripped out at the start of the film. It symbolizes the triumph of the traditional logocentric society. However, influenced by Keating's unconventional attitudes, ultimately Welton Academy will be changed as it is embodied in its closing scene.

  • An international survey of over 3600 academic researchers examined how trustworthiness is determined when making decisions on scholarly reading, citing, and publishing in the digital age and whether social media and open access publications are having an impact on judgements. In general, the study found that traditional scholarly methods and criteria remain important across the board. However, there are significant differences between younger (age 30 & under) and older researchers (over 30). Thus younger researchers: a) expend less effort to obtain information and more likely to compromise on quality in their selections; b) view open access publishing much more positively as it offers them more choices and helps to establish their reputation more quickly; c) compensate for their lack of experience by relying more heavily on trust markers and proxies, such as impact factors; d) use all the outlets available in order to improve the chances of getting their work published and, in this respect, make the most use of the social media with which they are more familiar.

  • ln this study, we analyzed 5 science textbooks currently used for the 7th graders quantitatively by using the science textbook rating system of Collette and Chiappetta(1986), making meta-analysis of the results of 17 graduate school students of Seoul National University. The rating system consists of 11 categories with detailed items respectively : content, organization, reading level, instruction approach, illustrations, end-chapter teaching aids, laboratory activities in text and/or accompanying manual, teacher aids, indices and glossaries and mechanical makeup of text. Each item in the checklist is to be given between one and five points and the total number of possible points in this rating system is 290. It was shown that 5 science textbooks currently used for 7th-year-students were all "poor" in terms of total points and had, at large, uniformed results especially in 10 items; 7 items concerning moral and ethical implications of science, vocabulary lists, accompanying laboratory manual, annotated editions for test, supply list for laboratory program, student workbook and glossary with low points, while 3 items concerning facilities needed for laboratory activities, activities relevant to the content and textbook size with high points. A Science teachers could get a broad view with a correct impression of the books usefulness in making an evaluation of available textbooks.

  • If an error occurs in the automatic mode when the advanced teleoperator system performs a task in hostile environment then the automatic mode changes into the manual mode. The operation by the control program and the operation by a human recover the error in the manual mode. The system resumes the automatic mode and continues the given task. It is necessary to improve the manual mode in order to make the best use of a man-robot system, as a part of the human interface technique. Therefore, the error recovery task is performed by combining the operation by the control program representing autonomy of a robot and the operation by a human representing versatility of a human operator effectively in the view point of human factors engineering. The geometric inverse kinematics is used for the calculation of the robot joint values in the operation by the control program. The singularity operation error and the parameter operation error often occur in this procedure. These two operation errors increase the movement time of the robot and the coordinate reading time, during the error recovery task. A singularity algorithm, parameter algorithm and fuzzy control are studied so as to remove the disadvantages of geometric inverse kinematics. And the geometric straight line motion is studied so as to improve the disadvantages of the operation by a human.
