The purpose of this study is not only to widen and deepen the understanding of external environments of hairstyle but also to provide the basis of understanding and perspicacity as to the hairstyle which will be created under the influence of new music by contemplating distinctions between Glam Fashion and Punk Fashion of 1970s and by comparing and analyzing distinctions between Glam Hairstyle and Punk Hair Style of 1970s. As the method of this study, first of all four common factors, which are resistance, androgynous, beauty of ugliness and pursuit of pleasure through persona, were able to be ed from both Glam Fashion and Punk Fashion of 1970s, and then by using that factors as analyzing instrumental frame, the above two hairstyles were compared and analyzed through photographic materials in this study. According to the results of comparing and analyzing two hairstyles above, in Glam Hairstyle, the androgynous character is the most remarkable distinction. They tried to overturn the gender role by challenging the traditional color and form of hairstyle. In funk Hairstyle, the resistance is the most prominent distinction. They expressed their group identity resisting a pre-existing generation by putting on threatened and aggressive hairstyle.

The purpose of this paper is developing a speech recognition module in a wheelchair for the sake of convenience. of the disability. For this system, we used TMS320C32 as a main processor; eliminated noise by applying Winer filler while considering characteristics of noise environment in pre-processing stage, and; extracted 12 feature patterns per france using LPC&Cepstrum. Then, we implemented the hybrid form combining DTW (Dynamic Time Warping), which is generally used for isolated words in the conventional algorithms, in the recognition Part, and NN (Neural network) to prevent any error of recognition. In this research, we achieved a recognition rate of more than 96% on isolated words when DTW and Hybrid forms were individually experimented in noise environment

We examined some problems in speaker identification procedures: transformation of acoustic parameters into auditory scales, invalid measurement values, and comparability of spectral energy values across the frequency range. To resolve those problems, we analyzed the acoustic spectral energy of three Korean numbers produced by ten female students from narrow-band spectrograms at 19 proportional time points of each voiced segment. Then, cells of the first five spectral matrices were averaged to form a matrix model for each speaker. The correlation coefficients and sum of the absolute amplitude difference in each pair of the spectral models of the ten subjects were obtained. Also, some individual matrix models were compared to those of the same subject or the other subject with a similar spectral model. Results showed that in numbers '2' and '9' subjects could not be clearly distinguished from the others but in number '4' it shed some possibility of setting threshold values for speaker identification if we employed the coefficients and the sum of absolute difference. Further studies would be desirable on various combinations of the range of long-term average spectra and the degree of signal pre-emphasis.

This paper presents a new two-point approximation method based on the exponential intervening variable. To avoid the lack of definition of the conventional exponential intervening variables due to zero- or negative-valued design variables the shifting level into each exponential intervening variable is introduced. Then a new quadratic approximation, whose Hessian matrix has only diagonal elements of different values, is proposed in terms of these intervening variables. These diagonal elements are computed in a closed form, which correct the typical error in the approximate gradient of the TANA series due to the lack of definition of exponential type intervening variables and their incomplete second-order terms. Also, a correction coefficient is multiplied to the pre-determined quadratic term to match the value of approximate function with that of the original function at the previous point. Finally, the authors developed a sequential approximate optimizer, solved several typical design problems used in the literature and compared these optimization results with those of TANA-3. These comparisons show that the proposed method gives more efficient and reliable results than TANA-3.

This study action drama TV drama 'Ya-ha'(夜叉) the actual work practices of the pre-consultation stage through the Writers, Producer, Art directors and in consultation with the opinion of the character set the record of the contents and character changes over time in accordance with characters makeup the design elements were analyzed. The methods of study was used local and abroad related books, studies, publications and cases and the subjects were limited to be four male make up characters in drama 'Ya-cha'. As a result, TV action drama 'Ya-cha' make up design elements and representation techniques were classified as description of skin tone, wound, the shape of eyebrows, hair type, shape of beard and materials and carried out an important role in the character representation. First, presentation techniques changed skin tones depending on character and position and described wound shape as expression technique and materials were analyzed. Second, the shape of eyebrows was based on the physiognomy of the form. And hair type changed volume, thickness, length and texture depending on character. Third, shape of beard is expressed different kinds of volume, thickness, length and texture depending on character. There fore, that systematization of the make-up design elements is useful to express stable characters and make drama for make up in various image genres.

ADS-B(Automatic Dependent Surveillance-Broadcast) has been recognized as a key component of Surveillance and ATM in CNS/ATM System. In addition to providing surveillance for air traffic control(ATC), ADS-B also supports airborne applications such as enhanced traffic situational awareness through the display of other aircraft to pilots and flight crew. It provides the real-time and same air traffic information to pilots in the aircraft cockpit, air traffic controllers in tower and surface vehicles on the ground at the same time. Aircraft Cockpit Display Unit will display the given information precisely and accurately. This paper describes progress in the development of a Cockpit Display with ADS-B data that enable pilots to acquire, verify and maintain pre-defined spacing intervals from other aircraft for general aviation and small regional aircraft. The designed display provides analogous information in the form of traffic position, range, and ground speed, etc.

Six sigma management has obtained good results in manufacturing and service industry as a new innovation approach to improve the enterprise-wise quality processes. However, there are lacks of implementation cases in the construction industry and furthermore, a results from a few cases applied is not successful enough to draw an attraction against the six sigma method. The main goal of this paper is to provide a comparative study regarding the pre-requisite conditions for the application of six sigma to the construction industry. Then, it present a generic procedure model that can support the introduction of six sigma management. Finally, the model is verified through the case study and lessons learned form a case are presented.

This paper presents a simple method for relieving the ambiguity problems within the sub-voxel based surface-fitting approach for the surface construction. ECB algorithm is proposed to avoid the ambiguity problem which is the root of the holes within the resulting polygon based approximation. The basic idea of our disambiguation strategy is the use of a set of predefined modeling primitives (we call SMP) which guarantees the topological consistency of resulted surface polygons. 20 SMPs are derived from the extension of the concept of the elementary modeling primitives in the CB algorithm [3], and fit one to five faces of them to the iso-surface crossing a cell with no further processing. A look-up table which has a surface triangle list is pre-calculated using these 20 SMPs. All of surface triangles in the table are from the faces of SMPs and are stored in the form of edge list on which vertices of each surface triangle are located. The resulted polygon based approximation is unique at every threshold value and its validity is guaranteed without considering the complicated problems such as average of density and postprocessing. ECB algorithm could be free from the need for the time consuming post-processing, which eliminates holes by revisiting every boundary cell. Through three experiments of surface construction from volume data, its capability of hole avoidance is showed.

3D convolution is to stack multiple consecutive frames to form a cube, and then apply the 3D convolution kernel in the cube. In this structure, each feature map of the convolutional layer is connected to multiple adjacent sequential frames in the previous layer, thus capturing the motion information. However, due to the changes of pedestrian posture, motion and position, the convolution at the same place is inappropriate, and when the 3D convolution kernel is convoluted in the time domain, only time domain features of three consecutive frames can be extracted, which is not a good enough to get action information. This paper proposes an action recognition method based on feature fusion of 3D convolutional neural network. Based on the VGG16 network model, sending a pre-acquired optical flow image for learning, then get the time domain features, and then the feature of the time domain is extracted from the features extracted by the 3D convolutional neural network. Finally, the behavior classification is done by the SVM classifier.

Since the middle of 1990's, domestic apartment building suppliers have set up brand images to overcome the difficulties in financial situation after IMF foreign exchange crisis. The main trends in recent apartment buildings could be classified generally into several types, such as 'Ubiquitous Intelligent(standing for High-tech)', 'Walkable Community(community-friendly)', 'Eco-friendly', 'Ergonomic Humanity(Human Engineering)', 'e-easy Home through Internet(Digital Home)'. With those brand images, construction enterprises have been making inroads into local apartment markets, especially one of the region around Dae-gu. It is meaningful and worth researching and analyzing the local residents' preferences and tendencies to form marketing strategies of brand images. Here, this research and analysis is of pre-examination before getting down the study of this subject.
