In multimedia fingerprinting field, it is many used a code based on BIBD, which has a strong resiliency of anti-collusion. When a collusion-attack code is generated with a logical XOR operation using the code based on BIBD, then some cases are occurred that a colluded code could be generated to the same fingerprint of non-colluder on the other hand, the colluder is decided to the non-colluder so that he would be excepted in the colluder tracing. For solving the serious problem of the wrong decision of the colluder tracing in this paper, XOR-ACC is implemented using multi-layer perceptron neural network among (AND, OR, XOR and Averaging)-ACC by the measured correlation coefficient. Through the experiment, it confirms that XOR-ACC efficiency of multimedia fingerprinting code{7,3,1} based on BIBD is improved to 88.24% from the conventional 41.18%, so that a ratio of the colluder tracing is also improved to 100% from the conventional 53%. As a result, it could be traced and decided completely a sectional colluder and non-colluder about the collusion attacks.

Recently realistic descriptions have been frequently used in anti-smoking campaigns. The same trend can also be seen with regard to posters as a medium of visual communication. It was intended to examine how different types of visual images in anti-smoking campaign posters produced and distributed by the WHO can improve the effectiveness of health communication. This article aims to determine how each of abstract/stylized illustrations and realistic images might affect the three key variables of the Theory of Planned Behavior, which are Attitudes toward the Behavior, Subjective Norms and Perceived Behavioral Control, in relation to quitting smoking. Results showed that realistic images are different in improving the attitudes toward the behavior and subjective norms. However, there are no significant difference between abstract/stylized illustrations and realistic images in Perceived Behavioral Control. The findings of this study suggest that the above-mentioned types of visual information achieve different levels of effectiveness in health communication. It is desirable that more effort be devoted to the interdisciplinary study across the areas of visual design and social psychology, for example, with a view to developing better health communication strategies.

The purpose of this study is to examine a distinctive feature and meaning of Reggae fashion and to establish a form of design on the basis of the Reggae style appeared in the 1990s. For the study, we review a formative background and stream of the Reggae fashion. And then, characteristics of the Reggae fashion is clarified through analyzing street fashion and High-fashion. The result of the analysis demonstrates that the Reggae fashion as a general term of the fashion style is connected to the Reggae musci emerged from Such socio-cultural changes as the tendency of the anti-fashion , the influence of the Afro-fashion , and the popularity of the Reggae music. The reggae fashion has been altered in terms of its style with the lapse of time-Rastafaran style, Raggnuffins and Bhangra style, Hip-hop Reggae style. The Reggae fashion emerged in the 1990s falls into three styles ; Afro-Reggae style, Feminine Reggae style, and Sporty Reggae style. The above mentioned results demonstrate that the design of Reggae fashion targets fro a youth in one's early 20s following a tendency in the 1990s and the 2000s. The design concept represents Romantic Reggae.

Creative design acquires value-added quality in fashion business. The anti-aesthetic Belgian designers who have been rebelling within strict rules are admired internationally, having reached the top-ten lists in the Journal do Textile in the 1990s. Moreover, they have set the trend in new progressive fashion. In the age of domination by marketing, these people have succeeded in, their integrity, their free spirits, and their passion for what they do. The interaction between their creativity, which is visible throughout their design process, and commercial interests is the key to the success of Belgian fashion. It is also noteworthy that the designing process is strongly linked together with flexible coordination. This analysis on the creativity of Belgian fashion design based on theoretical studies and interviews with Belgian designers from magazines and newspapers. The research includes the following main topics: 1. Analysis on the creativity of designing process. 2. Analysis on characteristics of Belgian fashion design.

The attempt to find the origin of Post-modern aesthetics from the Middle Ages is easy to perceive the thinking system of contemporary design. The Middle Ages showed that things and God's relation were symbolized all things were connected with analogical ideas as mysticism(alchemy, gnosticism), and God's world was represented with the metaphor. While the hybrid style of Post-modern architecture expressed that the rationalism was opposed to Ideology, partly, the idea of irrational with mysterious, also unscientific with analogical discourse . And the Symbolism of Post-Modern Design is means of popular Communication. Exactly, the common feature of ideology with pre-rationalism and anti-rationalism are against the dominated ideology in present. In conclusion, the relation of significancy effect In Chaos and In composition can be considered inspirational source historically.

For a vehicle Anti-lock Braking System (ABS), the control target is to maintain friction coefficients within maximum range to ensure minimum stopping distance and vehicle stability. But in order to achieve a directionally stable maneuver, tire side forces must be considered along with the braking friction. Focusing on combined braking and turning operation conditions, this paper presents a new control scheme for an ABS controller design, which calculates optimal target wheel slip ratio on-line based on vehicle dynamic states and prevailing road condition. A fuzzy logic approach is applied to maintain the optimal target slip ratio so that the best compromise between braking deceleration, stopping distance and direction stability performances can be obtained for the vehicle. The scheme is implemented using an 8-DOF nonlinear vehicle model and simulation tests were carried out in different conditions. The simulation results show that the proposed scheme is robust and effective. Compared with a fixed-slip ratio scheme, the stopping distance can be decreased with satisfactory directional control performance meanwhile.

The tilting pad journal bearings have been widely used to support high pressure/high rotating turbine rotors owing to their inherent dynamic stability characteristics. However, fatigue damages in the upper unloaded pads and the break of locking pins etc. by pad fluttering are continuously taken place in the actual steam turbines. The purpose of this paper is to develop a new bearing model that can prevent bearing problems effectively by pad fluttering in a tilting pad journal bearing. A new bearing model which has a wedged groove is suggested from the studies of fluttering mechanism performed by previously research works. The fluttering characteristics of the upper unloaded pad are studied experimentally in order to verify the reliability of a new bearing model. It can be known that the phenomenon of pad fluttering nearly does not occurred in the new bearing model under the various experimental conditions. And it is observed that any kinds of bearing failures by pad fluttering does not detect in the application of acture steam turbines.

Frank O. Gehry is known to be an architect whose work ranges over different realms, especially between fine arts and architecture. He himself mentioned about this interdisciplinary aspect of his own work: he was inspired by, worked together with, and sometimes directly influenced by contemporary artists. Among the artists, the most influential ones are the sculptors, especially Richard Serra of Post-Minimalism and Claes Oldenburg of Pop Art. Based on this historically known fact, although very brief, this study explores how the features of Post-Minimal sculpture were transferred into Gerhy's architecture, and how Gehry has developed them into his own language. In Post-Minimal sculpture, the main concept 'Anti-Form' was realized by emphasis on materiality, process and intuitiveness of work of in. Those features appeared vividly in Gehry's works especially in his second stage of his life, but seemed to have disappeared in the third stage. However, in the fourth stage, Gehry went beyond the influence of Post-Minimalism, and he created very unique formal language dialectically formed between Post-Minimal sculptural language and his architectural language.
