In this paper, a low area timing synchronization structure for the IEEE 802.11a OFDM MODEM SoC is proposed. The timing synchronization block of the IEEE 802.11a OFDM MODEM SoC requires large implementation area. In the proposed timing synchronization structure, it is shown that the number of multiplication can be reduced by using the transposed direct form filter. Furthermore, implementation area of the proposed structure can be more reduced using CSD(Canonic Signed Digit) and Common Sub-expression Sharing techniques. Through Verilog-HDL coding and synthesis, it is shown that the 22.7 % of implementation area can be reduced compared with the conventional one.

Internet based on web service is growing rapidly and the effort to standardize the next generation web is wold-widely being made. When the web was developed for the first time, HTTP, HTML, and URL were designed based on the structure of text background. Through those asynchronous search and simple unified expression patterns have been used But recently many data on internet me becoming complicated Consequently new structure and expression patterns including synchronous multimedia information are requested The currently used standard language among user interface domain of W3C is SMIL which is XML-based one SMIL describes where and how long the multimedia factors are integrated on the web. In this paper the standardization trend and important issues related to SMIL are reviewed and analysed Also the development of technology is discussed.

The mid-schedule planning of the ship is making a schedule about the process from cutting to erection. The ship consists of lots of blocks. This block has different process because of the shape of the block varies in accordance with the ship-type and the part position of the ship. The type and order of each block process initially must be generated for the mid-schedule planning. In this paper, the process planning, described as above is preparing the basic information before scheduler make a plan with the prepared manhour. The scheduling is done with this process planning which includes the information of the process order. This paper shows the research about three methods to design the process planning. First, investigate the expression method about information of the process planning for the mid-schedule planning in real workplace. Second, design the object of the process planning on the basis of investigating the expression method. Finally, develop the prototype of object on the basis of this designed process planning and then find the practical use in the mid-schedule planning. The object, which is developed in this paper, contains the main algorithm. In case of developing The Mid-Schedule Planning System, this object is expected to be utilized very easily as consisting another object.

Unlike the feature of SNS, which strengthens two-way communication and promotes interaction through consistent on/off line identity management, passive use of Facebook to unilaterally accept other people's opinions is being strengthened, and more people tend to use Facebook anonymously or pseudonym to enjoy freedom of expression. To illustrate this transformative use behavior, this study suggests an integrated model including psychological and behavioral variables such as self-esteem, real name use, and opinion expression to explore the effect on social relationship value perception and satisfaction. Studies have shown that self-esteem affects the use of real names and self-exposure, and that the satisfaction and sustainability of relationships have increased as real-name users expose more information about themselves.

The purpose of this study is to comparatively examine techniques and expressive characteristics of batik by focusing on the work of DanZhai and that of ZhenNing Buyi. We collected 50 pieces of batik each from Miao and Buyi in Chinese GuiZhouSheng and then analyzed their colors and patterns. The findings show that most of Miao's batik had deep and soft tones, while that of Buyi most often had blackish tone since the number of dyes in the latter is higher than that in the former. Miao often used patterns expressing animals or animals and plants, while Buyi frequently used geometric ones. An examination of specific motifs demonstrated that butterflies, fish, and flowers were most often used by Miao, while dots, vortexes, lines, and lozenges were frequently utilized by Buyi. For expressive techniques, both Miao and Buyi commonly used simple stylized expression or complex expression combining stylized and geometric techniques. Maio's motifs were often decoratively expressed with delicate curves, while Buyi's motifs had simple structures, so pictures were neatly expressed with thick lines and wide and simple planes. For the composition of the motifs, incomplete symmetry between top and bottom and between left and right often appeared in Maio, while in Buyi complete symmetry was frequently shown.

Streptococcus mutans, one of a major causal agents of dental caries, is component of the dental plaque and produces various organic acids such as lactic acid as the end-product of glycolysis. In this study, we isolated S. mutans from Korean children with caries and also investigated the expression of protein under acid stress. S. mutans was identified at the species level using a 16S ribosomal DNA sequencing comparison method. The primer specificity was tested on eleven S. mutans strains isolated from Korean children with caries. The data showed that eleven strains are S. mutans. At treatment of concentration of 20 mM lactic acid in the mid-log phage, K-7 exhibited the highest maximum culture OD compared with those of other groups. As a consequence, we examined the expression of protein under 20 mM lactic acid stress using S. mutans K-7. The results of 2D gel electrophoresis by image analysis showed that thirteen proteins are up-regulated under the stress. Further study is being focused on amino acid analysis by mass spectrometry in order to analyze those spots.

Immune-inspired intrusion detection is a promising technology for network security, and well known for its diversity, adaptation, self-tolerance, etc. However, scalability and coverage are two major drawbacks of the immune-inspired intrusion detection systems (IIDSes). In this paper, we propose an IIDS framework, named GEP-IIDS, with improved basic system elements to address these two problems. First, an additional bio-inspired technique, gene expression programming (GEP), is introduced in detector (corresponding to detection rules) representation. In addition, inspired by the avidity model of immunology, new avidity/affinity functions taking the priority of attributes into account are given. Based on the above two improved elements, we also propose a novel immune algorithm that is capable of integrating two bio-inspired mechanisms (i.e., negative selection and positive selection) by using a balance factor. Finally, a pruning algorithm is given to reduce redundant detectors that consume footprint and detection time but do not contribute to improving performance. Our experimental results show the feasibility and effectiveness of our solution to handle the scalability and coverage problems of IIDS.

A scenario known as conflict in face recognition may arise as a result of some disparity-related issues (such as expression, distortion, occlusion and others) leading to a compromise of someone's identity or contradiction of the intended message. However, addressing this requires the determination and application of appropriate procedures among the various conflict theories both in terms of concepts as well as resolution strategies. Theories such as Marxist, Game theory (Prisoner's dilemma, Penny matching, Chicken problem), Lanchester theory and Information theory were analyzed in relation to facial images conflict and these were made possible by trying to provide answers to selected questions as far as resolving facial conflict is concerned. It has been observed that the scenarios presented in the Marxist theory agree with the form of resolution expected in the analysis of conflict and its related issues as they relate to face recognition. The study observed that the issue of conflict in facial images can better be analyzed using the concept introduced by the Marxist theory in relation to the Information theory. This is as a result of its resolution strategy which tends to seek a form of balance as result as opposed to the win or lose case scenarios applied in other concepts. This was also consolidated by making reference to the main mechanisms and result scenario applicable in Information theory.

Information visualization is divided into delivery, description, and beautiful fun. The dilemma is delivered to the user by emphasizing a certain part of the data as a visual rhetorical expression after grasping the table format and content of the data. The visual rhetoric representation used at this time helps users deliver content, but the data graphics used have a dilemma that becomes some false. In this study, errors that occur in rhetorical descriptions such as paradox, gradation, omission, synecdoche, meter, enumeration, and metaphor were discussed. Errors include graphic areas that differ from data values, showing only selective data, inappropriate use of grids, misunderstanding simple geometric depictions, and inappropriate graphic blocking.
