박찬길,김정재,이경석,전문석,Park, Chan-Kil,Kim, Jung-Jae,Lee, Kyung-Seok,Jun, Moon-Seog 한국정보처리학회 2006 정보처리학회논문지 C : 정보통신,정보보안 Vol.13 No.7

본 논문에서는 기존의 암호화 방법보다 안전한 키를 생성하는 해쉬체인 알고리즘을 제안하며, 해쉬체인 알고리즘 기법을 통해 생성한 각각의 키를 각각의 블록에 적용한 암호화 방법을 사용하여 기존의 시스템보다 보안성이 높은 암호화 방법을 제안한다. 또한 사용자 인증기법을 통해 사용자를 유/무선으로 인증한 후, 키 분할 기법을 이용하여 분할된 키를 안전하게 전송하는 방법과 클라이언트에 키가 유출되어도 완전한 키를 얻지 못하도록 하는 세션키 분할 기법을 제안한다. 제안한 시스템을 설계하고 구현한 후 성능 평가를 위해 다양한 크기의 디지털콘텐츠 파일을 이용하여 실험을 수행하였으며, 제안한 시스템이 기존 시스템에 비해 안전한 키 전송을 할 수 있었고, 키 유출에도 전체 데이터를 복호화 할 수 없도록 암호화 하였다. 또한 클라이언트 시스템에서 비디오 데이터 파일 재생 시 암호화 복호화 시간은 기존 방법과 유사함을 확인하였다. This is devoted to first, to propose a hash chain algorithm that generates more secure key than conventional encryption method. Secondly, we proposes encryption method that is more secure than conventional system using a encryption method that encrypts each block with each key generated by a hash chain algorithm. Thirdly, After identifying the user via wired and wireless network using a user authentication method. We propose a divided session key method so that Although a client key is disclosed, Attackers cannot catch a complete key and method to safely transfer the key using a divided key method. We make an experiment using various size of digital contents files for performance analysis after performing the design and implementation of system. Proposed system can distribute key securely than conventional system and encrypt data to prevent attacker from decrypting complete data although key may be disclosed. The encryption and decryption time that client system takes to replay video data fie is analogous to the conventional method.

Wordsworth defined poetry as "spontaneous overflow of powerful feelings," but he never wrote his poems "spontaneously." Quite to the contrary, he revised the drafts again and again even after manuscripts were in the publisher`s hands giving him the notorious title of a "publishers` nightmare." The Prelude being the prime example, he sometimes decided not to publish the poems he had laboriously revised for a long time. The Ruined Cottage, generally regarded as one of the finest achievements of Wordsworth`s entire poetic career, was another example that was never given the chance to be published as a separate poem in Wordsworth`s lifetime. Wordsworth started to work on it from as early as 1796 and presented it to the world after many revisions in 1814 as the first book of The Excursion. Even after publication, the poet did not stop tinkering with the poem until as late as 1845, five years before he died. There is no doubt that the Cornell edition of The Ruined Cottage is an example of the best textual scholarship imaginable within the limits of print book technology, but its use has been by and large limited to Wordsworth specialists. My objective is to present a conceptual model of a multi-layered electronic edition of The Ruined Cottage, making use of recently developed encoding technique, which we hope will render the results of textual scholarship contained within the Cornell edition more readily available to the general readers through multimedia visualizing technology. Making the best of all the useful knowledge from the preceding research, we hope to contribute to the scholarship of electronic text with our multi-layered electronic text of The Ruined Cottage by incorporating: - User-friendly interface using multimedia visualization techniques - Three-dimensional graphic images showing the depth of multi-layered e-texts - VR navigation techniques to feel the volumetric effects of the layers - Comparison among various hypertext poems using XML techniques - Graphical rendering with the original calligraphy and material according to the change of some parts in the e-texts Wordsworth`s life-long textual manipulation of his major works makes him in hindsight a precursor to the hyper-textual author: he, for example, had an ambition to organize all his poetic texts into one great work allocating a proper place for each poetical text in the hierarchical structure of his poetic corpus where each poem is implicitly or explicitly cross-referenced ("linked") with each other, which was all done within the limits of print book technology. The textual history of any single poem of Wordsworth, therefore, cannot be revealed until it is shown within the complex web-like structure of his poetic corpus. The multi-layered electronic text with its three-dimensional visualizing technique could offer a clearer picture of a poem`s connection to the Wordsworthian docuverse system, The Ruined Cottage first to be show-cased.

시적 전통과 언어 실험: 『서정담시집』의 서정성

The real "lyrical ballads," the direct result of Wordsworth`s poetic experiment, are not only fewer in number but also less attractive as a research agenda in Wordsworth scholarship than the "other poems" of the Lyrical Ballads. This article is yet another attempt to understand what Wordsworth meant by "lyrical ballad" and to revaluate the "lyrical ballads" as the centerpiece of his poetic experiment. Wordsworth scholars have understood the idea of "lyrical ballad" in two ways: as a technical improvement of the "literary ballads" then in vogue, and as a new kind of ballad with an in-depth study of the human subjectivity. The "lyrical ballads" as are materialized in the collection, however, seem rather unique in having "lyrical moments" where the readers are made to share the poet`s (or the narrator`s) insight into something permanent and infinite, something beyond human imperfection. Such moments of lyrical recognition are achieved in various ways: sophisticated devices of meter with moral intention, lyric figures with inhuman innocence, and unique narrative frameworks containing lyric epiphany. The lyric nature of "lyrical ballad" seems meaningful because it allows us to establish the integrity of the "lyrical ballad" project as an experiment of poetic diction. It also allows us to comprehend the unity of Wordsworth`s poetic intention regarding various elements of the collection such as the proper lyrical ballads, traditional lyrics, and the new poetic theories presented in the Advertisement and the Preface. It is also helpful in repositioning Lyrical Ballads as the true starting point of the poetic revolution Wordsworth thought himself conducting to the end of his life.

The recent development in the university evaluation system in Korea has rumed out to be extremely detrimental to academic research, particularly in the humanities. The corporatization of higher education in Korea imposes a problematic evaluation system on humanist scholars in that ir places them under enormous pressure to publish at a rate incompatible with humanities scholarship. This paper critically examines the validity of the current university evaluation system in the humanities from a humanist scholar`s viewpoint. By analyzing the official statistics on humanities scholarship of Korean universities between 2011-2012, this paper argues that present publication requirements for humanities professors go well beyond their narural research capacity. It is highly unlikely, however, to rectifYsuch a problem without exempting humanities scholarship from the race of unlimited competition taking place in the global market of higher education represented by world university rankings. Research performance in the humanities should be assessed with a new evaluation system reflecting a good understanding of the nature of humanities scholarship such as distinctiveness, diversity, and locality.

This paper aims at examining the emerging academic discipline called "humanities computing" particularly in regard to the literary studies that finds itself within a strange cultural environment of new media. The first part is a general survey of the origin and the subsequent developments of humanities computing beginning from Roberto Busa`s concordance of Thomas Aquinas, which is followed by a critical discussion of Willard McCathy`s definition. John Unsworth`s theoretical explanation of humanities computing as an academic discipline is also examined. The second part is a full-scale discussion of the hypertext theory in regard to its enormous impact upon the topography of traditional literary studies. The theories of hypertext are critically examined particularly regarding its positive or negative effects on the traditional literary scholarship. Ted Nelson`s famous definition, James Bolter`s classic idea of hypertextual "writing space," George Landow`s quick-witted summary of hypertext as a perfect embodiment of deconstructive textual theories are all discussed in detail. The conclusion is that the humanities computing`s contribution to the literary scholarship is real and substantial enough by any standard, but have not quite lived up to what some enthusiasts had claimed; humanities computing has been useful more as a technical assistance than as a whole new academic discipline so far. But humanities computing has done enough to present itself as the most feasible way available for humanities scholars to adapt themselves to the quickly evolving culture of information society

"웹을 이용한 문화연구": HCRG의 디지털인문학 과목개발전략

This paper begins with the fundamental dilemmas of the culture class offered by the literature departments such as the obscure boundary of the culture class, the lack of professional qualification of the literature and linguistics major professors, and the inflexible curriculum of the current university system. "A Study of Culture with Web" is a pilot project to figure out a way to solve or alleviate such dilemmas with a new pedagogical paradigm materialized by a new model of an off-line culture class making the best of web-based cyber class environment. The main part of this paper is a detailed explanation of the rationale of the newly developed website containing "A Study of Culture with Web" with captured images of major menus: Webcontents, Exhibition, Database, and Hypertext Lecture Notes. These manual type descriptions however are given as the technological expressions of a series of new pedagogical disciplines such as teaching as collaboration rather than unilateral lecturing, active learning, bi-directional interchanges between teacher and student, and the curriculum as the continuum. The next section examines the possible constructive effects the new pedagogy of "A Study of Culture with Web" may bring about. This paper argues that the new pedagogical model materialized by the menus of HCRG website might be not only a possible way-out from the dilemmas of the culture class within the curriculum of literature departments but also a promising model of the liberal education in general that is under increasing pressure from the rapidly changing information society. This paper concludes the argument by offering a few conditions for the success of "A Study of Culture with Web": the continuous update of the database with quality contents, the correct understanding of the new pedagogical disciplines by both teachers and students, the priority of humanistic thinking over the technological maneuverings, and more systematic institutional supports for the pioneering teachers who develop, maintain, and upgrade the forward looking educational device of the information society.
