  • The purpose of this study was to provide a master plan for the establishment of a Korean National Museum of Natural History. The origin and development of the natural history and the natural history museum were surveyed by visiting not only Korean natural history museums but also foreign ones from 1987 to 2009. Based on the obtained information, the qualitative and quantitative status of Korean natural history museums was comparatively analyzed in terms of globalization. Results indicated that Korean natural history museums ranked more than 100th in the world, and the research, management, and publications were situated in a rudimentary stage. Particularly, the number of researchers within the area was too small, and the research environment was poor in its function and resources. In addition, the specialists on exhibition and education of the museums were too few to publish the research products and academic journal articles. For that matter, a strategy as the research-specimen management-publication-exhibition-education functions should be in place to operate before the construction of National Museum of Natural History begins.

  • Recently, the renewable energy resources play an important role as an energy resources of future due to an environmental pollution and lack of resources and so on. The development and diffusion of information systems related to renewable energy resources have been driven actively abroad. However, at domestic an efficient history management for renewable energy resource data and web retrieve service are not provided. Therefore, in this paper, we propose a history data management system for the renewable energy resources, which stores and manages vast history information of renewable energy resource data systematically. This system collects renewable energy resource data in the outside observation system and stores them in the history database. The stored Information is retrieved through the history query process and can be provided in various forms - table, graph, chart and counter line, etc. - on the internet. Especially, the proposed system manages the history data in real-time so the latest information is always provided to the users through the web interface.

  • Branch prediction accuracy is critical for the overall system performance. Branch miss-prediction penalty is the one of the significant performance limiters for improving processor performance, as the pipeline deepens and the instruction issued per cycle increases. In this paper, we propose "Dynamic Per-Branch History Length Fitting Method" by tracking the data dependencies among the register writing instructions. The proposed solution first identifies the key branches, and then it selectively uses the histories of the key branches. To support this mechanism, we provide a history length adjustment algorithm and a required hardware module. As the result of simulation, the proposed mechanism outperforms the previous fixed static method, up to 5.96% in prediction accuracy. Furthermore, our method introduces the performance improvement, compared to the profiled results which are generally considered as the optimal ones.

  • Branch prediction accuracy is critical for system performance in modern microprocessor architectures. The use of speculative update branch history provides substantial accuracy improvement in branch prediction. However, speculative update branch history is the information about uncommitted branch instruction and thus it may hurts program correctness, in case of miss-speculative execution. Therefore, speculative update branch history requires suitable recovery mechanisms to provide program correctness as well as performance improvement. In this paper, we propose recovery logics for speculative update branch history. The proposed solutions are recovery logics for both global history and local history. In simulation results, our solution provides performance improvement up to 5.64%. In addition, it guarantees the program correctness and almost 90% of additional hardware overhead is reduced, compared to previous works.

Julian Barnes' Reconstruction of Identity, Nationality and History: England, England as a Historiographic Metafiction (줄리언 반즈의 정체성, 민족성 그리고 역사의 재건축 -히스토리오그래픽 메타픽션으로서의 『잉글랜드, 잉글랜드』)

  • Many recent British novels engage with the construction and deconstruction of history and identity; and in dealing with these historical, or historicised novels it seems to be an untouchable ground that truth is beyond grasp. Even when approached, its authenticity should be examined under the post-modern "incredulity toward metanarrative" discourses. Julian Barnes's 1998 novel England, England may be one of these. Yet, unlike others it achieves a complicated and controversial status as a new kind of historiographic metafiction by providing selfconscious reflections on the invention of innocence and the questionable notion of historical authenticity against the background of current postmodern historical, cultural, and literary explorations. The book, set in a near-future, namely post-post-modern England, starts with a story of a young girl, Martha Cochrane, whose first memory goes back to her early infantile years. Yet, the narrator comments that it is a lie, "her first artfully, innocently arranged lie," since memory, or history, is a product of identity, and vice versa. Her memory of the jigsaw puzzle is both a reminiscent and a significant component of who she is now, both a simulacrum and the original of herself. The correlation between her individual memory and identity parallels that of a region, England, in formation of its history and nationality. "England, England" is the replicated miniature of the former glorious Kingdom as well as a becoming der Ding an sich (the thing itself). In search of the English history and identity, the author satirizes the modern mind's perception of the unreliability and arbitrariness of memory and history, and further explores the alternative to the postmodern discourses by suggesting the probability of inventing innocence glimpsed in children's face "believing while disbelieving." In doing so, the author reconstructs not only the history of Englishness on the ground where nothing seems to be solid, but more importantly also the postmodern theme of relativity in relation to memory, history and identity.

  • Absalom, Absalom! is not only about family history but also about the nature of reconstructing history. Faulkner shows us what will happen if we give too much credit to the person having the authority; he first makes us listen to Rosa, so we just listen without doubt until we arrive at the question of the objectivity of her narration, when we get to know Sutpen's design. Meanings of "facts" change depending on who perceives the facts. The incremental repetition of the narrative in the novel resembles the process of our thinking mind and the process of history being constructed. Time is a significant element in determining the meaning of an event, not only because the event cannot be understood without its social, cultural context of the contemporary, but also because only the later events make it possible for the perceiver to categorize it in its proper place in history. Furthermore, through his narrative strategy, Faulkner suggests that imagination play a large part in recreating history. He blurs the distinction between facts and imagination, making us regard Shreve's and Quentin's conjectures as facts in several ways. The conversation between father and son, and the two brothers, which is an imagination constructed through the clues Mr Compson has offered, becomes a fact willingly accepted by the readers as well as Shreve and Quentin. The people in the past, present, and future may be very much unlikely to agree on the same event, because the gap in temporality will keep widening our perceptions. Faulkner demonstrates the nature of history in such a way that we can compare our understanding of the Sutpens' history in the earlier and later part of the novel through repetitions.
