최근 방송의 디지털화에 따라 수많은 채널의 수용이 가능하게 되어, 현재와 같이 신문의 방송편성표를 보고 사용자가 원하는 프로그램의 시작 시간을 알아내는 것은 힘들어 졌다. 디지털방송에서는 신문 방송 편성표와 같은 기능을 하는 방송 프로그램에 대한 정보를 보여주는 EPG(Electronic Program Guide)를 제공하고 있다. 현재 서비스되고 있는 EPG를 보면, 프로그램의 시작 시간을 GUI로 사용자가 쉽게 알아 볼 수 있어 하고 있어 신문 편성표나 인터넷으로 제공되는 각 방송국의 편성표와 달리 TV 화면에서 프로그램 정보를 검색할 수 있어 편리해졌다. 그러나 이 EPG에서 제공되는 시간은 매우 부정확하기 때문에 시청자가 불편을 느낄 수 있다. 본 논문에서는 방송의 시작 시간을 정확히 알아내어 EPG를 정확히 갱신하는데 목적이 있다. 이를 위해 방송의 시작부분을 미리 저장한 후, 시작 부분을 Visual Rhythm을 이용해 shot들을 추출하여 데이터베이스를 구성하고, 이와 같은 방식으로 방송 스트림의 shot들도 추출하여 데이터베이스와의 Pattern Matching을 통해 보다 정확한 방송시간으로 EPG를 갱신하고자 한다.

The purpose of this study is to understand the dissipation pattern of excess pore pressure after liquefaction which governs the post-liquefaction behavior of liquefied sand deposits. 1-g shaking table tests were carried out on 5 different kinds of sands, all of which had high liquefaction potentials. During the tests excess pore pressure at various depths, and surface settlements were measured. The measured curve of the excess pore pressure dissipation was simulated using the solidification theory, and from the analysis of the velocity of dissipation, the dissipation pattern of excess pore pressure after liquefaction was examined. The dissipation velocity of excess pore pressure after liquefaction had a linear correlation with the effective grain size ( $D_{10}$) divided by the coefficient of uniformity ( $C_{u}$), and the increase in the initial relative density of the ground played a role in shifting this correlation curve toward an increased dissipation velocity. From the correlation, an approximate method was recommended for prediction of the dissipation curve of excess pore pressure after liquefaction in saturated sand deposits.s.s.

Methods : Data was collected by structured survey papers from Korean Medicine doctors participate in the Conference of The Korean Oriental Medical Ophthalmology & Otolaryngology & Dermatology Society in October 2012. We investigated their representative Patterns(변증) of every questions and used the mean results for assuming agreement rates. The importance order of 8 symptom domains for considering Pattern diagnostic steps were also asked and analyzed for inducing importance rates. Finally based on above two results, we developed weight points of each questions by multiplying agrement percents with importance rates. Results : 50 Korean medicine doctors described the informed consent and survey papers. Response agreement rates of each questions of Pattern diagnosis instruments were analyzed and described in Table 2. Comparing the survey results with diagnostic references, matched percent of 肺胃熱 was the 87.9%, 肺氣虛寒 was 62.5%, 肺脾氣虛 was 62.5% and 腎元虧虛 was 50%. Mean importance rates of rhinorrhea was 7.28, otoscope diagnosis 5.12, obstruction 5.04, sneeze 4.82, symptom duration 4.63, other body condition 3.54, tongue diagnosis 3.02, nasal pruritus 2.86, accordingly. Final importance rates of each questions were assumed, and the range of them was from 1.60 to 4.72, which were listed in Table 5. Conclusion : These results might provide the rational backgrounds and practical methods for developing and utilizing methods of Pattern diagnosis questionnaire for perennial allergic rhinitis.

The main purpose of this paper is to describe a DTC (direct torque control) method for four-switch brushless dc motor (BLDCM) drive. In the method, a novel voltage space vector modulation scheme, an optimal switching table, and a flux observation method are proposed. Eight voltage vectors are summarized, which are selected to control BLDCM in SVPWM pattern, and an optimal switching table is proposed to improve the torque distortion caused by midpoint current of the split capacitors. Unlike conventional flux observers, this observer does not require speed adaptation and is not susceptible to speed estimation errors, especially, at low speed. Global asymptotic stability of the flux observer is guaranteed by the Lyapunov stability analysis. DC-offset effects are mitigated by introducing a PI component in the observer gains. This method alleviates the undesired current and torque distortion which is caused by uncontrollable phase. The correctness and feasibility of the method are proved by simulation and experimental results.

By examining the existing Galot products in the market, we aimed to discover areas for new development and lay out the foundational system for establishing a database(DB) of their pattern grading. For the analysis, the team focused mainly on Galot in forms of casual korean traditional clothes, since they have the largest market share. The main accomplishments from this research are as follows. First, because adult females are the largest segment to consider in deciding the size system for grading, we selected three sizes that have to be compatible with the KS Clothing Standardized Sizing. Second, for basic pattern grading, we applied the reference size indicated in KS Clothing Standardized Size, and also used half dart sloper and dartless sloper. Third, we categorized designs according to the presence or absence of a dart, the structure of closure, and the shape of the sleeve and neck. We indicated the grading points with numbers and body area in Korean to make it easier for the users to understand when using the computer system and doing manual work. To further increase the user convenience, we provided diagrams for categorized designs, pattern grading layout, and a table for calculated grading points variation.

DNA sequencing provides fundamental data in genomics, bioinformatics, biology and many other research areas. With the emergent evolution in DNA sequencing technology, a massive amount of genomic data is produced every day, mainly DNA sequences, craving for more storage and bandwidth. Unfortunately, managing, analyzing and specifically storing these large amounts of data become a major scientific challenge for bioinformatics. Those large volumes of data also require a fast transmission, effective storage, superior functionality and provision of quick access to any record. Data storage costs have a considerable proportion of total cost in the formation and analysis of DNA sequences. In particular, there is a need of highly control of disk storage capacity of DNA sequences but the standard compression techniques unsuccessful to compress these sequences. Several specialized techniques were introduced for this purpose. Therefore, to overcome all these above challenges, lossless compression techniques have become necessary. In this paper, it is described a new DNA compression mechanism of pattern matching extended Compression algorithm that read the input sequence as segments and find the matching pattern and store it in a permanent or temporary table based on number of bases. The remaining unmatched sequence is been converted into the binary form and then it is been grouped into binary bits i.e. of seven bits and gain these bits are been converted into an ASCII form. Finally, the proposed algorithm dynamically calculates the compression ratio. Thus the results show that pattern matching extended Compression algorithm outperforms cutting-edge compressors and proves its efficiency in terms of compression ratio regardless of the file size of the data.
