  • 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.

  • The aim of this study is to create a catalogue of amnesia synonyms in Traditional Korean Medicine for database utilization. A two-staged literature search was carried out. First, two databases(China National Knowledge Infrastructure:CNKI, Oriental Medicine Advanced Searching Integrated System:OASIS) were searched for eligible articles, and a set of candidate words was identified from the articles. Second, the candidate words were searched in 30 medical classics to check the frequency of use. As a result, 9 candidate words including 喜忘(huimang), 善忘(seonmang), 多忘(damang), 好忘(homang), 健忘(geonmang), 遂忘(sumang), 遺忘(yumang), 忘事(mangsa), and 易忘(imang) were identified from the 10 eligible articles. Among the 9 candidate words, 健忘(geonmang) was a descriptor and 7 other words including 喜忘(huimang), 善忘(seonmang), 多忘(damang), 好忘(homang), 遂忘(sumang), 遺忘(yumang), 忘事(mangsa) were non-descriptors. 易忘(imang) was not an adequate synonym for amnesia.

  • 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.

  • The Sa-am acupuncture is the acupuncture method created during Chosun Dynasty. It is a unique acupuncture method that was created solely in Korea. Its theories are based on the 69th article of "Classic of Difficult Issues", or Nanjing (難經), which says "tonify its mother when deficiency occurs, and purgate its son when excess occurs" (虛則補其母, 實則瀉其子); the concept of "controlling the viscera which restrains the target" "抑其官" was added to this theory to form the principle of Sa-am acupuncture. It is significant that it turns to the basic principles of the Five Viscera and Six Bowels rather than the 體針 or 阿是針 of the existing acupuncure. Sa-am acupuncture was established in the middle of Chosun Dynasty and was popularized to the practitioners of Korean Medicine through transcripts and printed books. The medical books of at the time of Japanese imperialism that introduced Sa-am acupuncture are "經絡學總論", "舍岩鍼灸訣", "經濟要訣", "靑囊訣", "察病要訣", "濟世寶鑑", "經驗寢具編", and "舍岩 靑囊訣". The magazine that mentions the Sa-am acupuncture is "韓方醫藥". The books on Traditional Medicine that is related to Sa-am acupuncture were of great help in reconstruction of Sa-am acupuncture after the liberation of Korea and explaining the principle of Sa-am acupunture in various angles.

  • 1) Objective External treatments have various curative effects. So it had been used to cure various patients. But, it has a limited sphere of application in the present South Korea. And the "Li-Yao-Pian-Won" had been written by Wu-Shang-Xian(吳尙先) in 1864. The book is the first technical book of external treatments. So, he has been held in respected as the father of external treatments by many people. Therefore we would like to bring out it's external treatments theory 2) Conclusions He had insisted that external treatments principles are identical with internal treatments. So, prescriptions of external treatment are selected and made by principles of internal treatment. But external treatments have following characteristics 1. Each of external treatment prescriptions have various effects. 2. Exchange of treatments is very easy. 3. We can make free use of various external treatments for care at a time. 4. External treatments are very economical. 5. External treatments are very easy to study. 6. External treatments are simple, speedy, precision.

  • This paper is the result of a research conducted for "Knowledge Resource Development by Excavation and preservation and DB Establishment of Traditional Home Remedy", a part of Korean Medicine knowledge infrastructure establishment and Korean Medicine therapy development project executed by Korea Institute of Oriental Medicine. This paper is a part of the plans to standardize Korean acupuncture and moxibustion and surgical techniques in order to make new techniques derived from Korean traditional medicine patentable, as presented in the Nagoya Protocol. By first reviewing traditional text sources and classifying them into index literature and index techniques, we can see a mutual relationship between these two categories. Based on current research papers, this study has established a total of 121 pieces of index literature as well as extracted 64 types of index techniques in acupuncture and surgery technique. Both index literature and index technique have been concurrently visualized in this paper in the "Korean Acupuncture & Moxibustion Technique and Surgical Manipulation Base Map".

  • When test tubes for PCM with melting point lower than a room temperature are installed vertically as the T-history method proposes, there exists a temperature distribution in the longitudinal direction by natural convection, which lowers the precision of measured heat-of-fusion. The purpose of the present work is to improve the precision by arranging the test tubes horizontally, while maintaining the simplicity and convenience. Assuming that the amount of heat transfer is very small through the vapor space formed in the upper part of the tubes by volumetric change, the obtained value by the T-history method using the latent heat period bounded by two inflection points is in good agreement with that of the literature. Also, the scattering of measured values by the proposed method decreases markedly compared to that of vertical positioning.

  • It is essential to determine a proper earthquake time history as a seismic load in a seismic design for a critical structure. In the code, a seismic load should satisfy a design response spectrum and include the characteristic of a target fault. The characteristic of a fault can be represented by a definition of a type of possible earthquake time history shape that occurred in a target fault. In this paper, the pseudo-basis function is proposed to be used to construct a specific type of earthquake, including the characteristic of a target fault. The pseudo-basis function is derived from analyzing the earthquake time history of specific fault harmonic wavelet transform. To show the feasibility of this method, the proposed method was applied to the faults causing the Gyeong-Ju ML5.8 and Pohang ML5.3 earthquakes.
