One of the most popular approaches to parameter adaptation in hidden Markov model (HMM) based systems is the maximum likelihood linear regression (MLLR) technique. In our previous study, we proposed factored MLLR (FMLLR) where each MLLR parameter is defined as a function of a control vector. We presented a method to train the FMLLR parameters based on a general framework of the expectation-maximization (EM) algorithm. Using the proposed algorithm, supplementary information which cannot be included in the models is effectively reflected in the adaptation process. In this paper, we apply the FMLLR algorithm to a pitch sequence as well as spectrum parameters. In a series of experiments on artificial generation of expressive speech, we evaluate the performance of the FMLLR technique and also compare with other approaches to parameter adaptation in HMM-based speech synthesis.

The objectives of this study were 1) to ascertain whether there was a difference in product performance (expressive or instrumental), which consumer recognized after using, related to consumer involvement toward clothing, 2) to clarify the effect of product performance on consumption emotion(positive or negative), 3) to investigate the effect of consumption emotion on satisfaction, and 4) to find out whether product performance had a direct effect on satisfaction toward product. The study was conducted in three steps. Through the two steps, measurement instruments were developed. At the last step, judgement sampling method were utilized to collect the data and subjects were 614 university students. Confirmatory factor analysis and structural equation model analysis were used to analyze the data. The results were as follows: 1) Consumer involvement had an effect on product performances but it was related to the expressive product performance more than to the instrumental product performance. 2) Product performance had positive influence on positive consumption emotion, while it had negative influence on negative consumption emotion. The results revealed that there were significant relationships between product performance and consumption emotion. 3) Positive consumption emotion had a positive effect on consumer satisfaction, on the other hand negative consumption emotion had a negative effect on consumer satisfaction. 4) Although the direct effects of product performances on satisfaction were larger than the indirect effects, product performance was greatly influential in consumption emotion and consumption emotion was strongly related to consumer satisfaction. Therefore, consumption emotion is an important determinant variable in the process of consumer satisfaction.

This study was initiated to add value to fashion illustration as a genre of plastic art, as its importance as a progressive visual art is growing. The research purpose is to analyze characteristics of Grotesque, a subculture that emerged from the challenges and problems of groups which deviated from social and cultural trends, and to develop fashion design illustration utilizing the characteristics unique to that subculture. As a method of research, this study examined the characteristics and expression methods of Grotesque, which appeared in fashion literature, referenced a prior study of Grotesque, and developed fashion design illustration using Grotesque as a based. The result of this study are as follows. First, the characteristics of Grotesque that are applicable to fashion illustration were derived as 'evil, aversion, playfulness, heterogeneity, and abnormality'. Second, the expressive elements of Grotesques, reflecting the beauty of ugliness, present a methodology for developing new and creative fashion design illustrations. Third, it was found that Grotesque fashion illustration is a visual tool that is suitable for expressing the problematic origins of human existence, values, alienation, and social chaos. Fourth, 'arthropod' motifs were identified as a suitable theme for extracting the newly integrated Grotesque images through the process of contradiction and confrontation between humans and objects. Fifth, the Grotesque fashion illustrations could be understood in terms of plastic arts, and could provide a gateway to rediscovering human dignity. Based on the finding, we expect that creative design thinking and development that combines the motifs of various themes and Grotesque's expressive methods will proceed more deeply and specifically.

Background and Objectives The present study aimed to compare receptive and expressive language development in children who have undergone simultaneous bilateral cochlear implantation (SCI) and those who have undergone bimodal stimulation (unilateral CI+ hearing aid). Subjects and Method In a retrospective analysis of clinical data, 15 pediatric patients who have received SCI and nine patients who have received bimodal stimulation (BM group) were enrolled. CI was performed for all patients at 24 months of age. Category of Auditory Performance (CAP) scores, Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) scores, and developmental quotients (DQ) for expressive and receptive language were compared between the groups at 12 month of follow-up. The Percentage of Consonants Correct (PCC) of children evaluated at 4 years old was also compared. Results At 12 months of follow-up, significantly greater improvements in CAP scores (${\Delta}4.25{\pm}0.5$) were noted in the SCI group compared to the BM group (${\Delta}3.56{\pm}0.88$, p=0.041). Significantly greater improvements in IT-MAIS scores were also noted in the SCI group (${\Delta}36.17{\pm}4.09$) than in the BM group (${\Delta}30.17{\pm}2.91$, p=0.004). The DQ of receptive language was higher in the SCI group than in the BM group ($87.6{\pm}15.4%$ vs. $75.5{\pm}12.0%$, p=0.023) at 12 months of follow-up. Moreover, early SCI was associated with better receptive language skills. PCC index of children at 4 years old was higher in the SCI group than in the BM group ($88.5{\pm}13.2%$ vs. $62{\pm}15.8%$, p=0.014). Earlier SCI was associated with even greater improvements. Conclusion Bilateral SCI is associated with significant improvements in language development when compared with bimodal stimulation. Earlier SCI was associated with better outcomes.

This study is an architectural and landscaping analysis view to rural landscape paintings painted by Vincent van Gogh in the late 19th century. The purpose of this research is to discover the expressive techniques of Western art that Van Gogh's landscape paintings have, and to understand the characteristics of the architectural object in his landscape paintings from February 1888 to April 1889 in Arles, southern France. The method of this study is to analyze the landscape paintings of Van Gogh painted during 15 months in Arles. Among the total paintings in Arles, 47% of the paintings he made were landscapes. The following conclusions have three views. First, Vincent van Gogh was born into a Protestant family in the Netherlands and become an artist in his late twenties. While living in Arles, he painted prolific landscapes. Farming, farmers, and rural area related to normal living are the main subjects of paintings. It can be seen as showing the view that everyday life is sublime and should be included as a unitary value. Second, Gogh's rural landscape paintings were painted with linear and aerial perspective with other the expressive techniques, and plane painting structure that leads to two dimension. Third, from an architectural point of view, Van Gogh's paintings depicted simple vernacular architecture such as traditional rural house, mas, thatched houses, and mills in southern France. This means the normal value of the rural landscape through the eyes of the painter.

This study analyzes the characteristics of each element of neo-deconstructivist fashion design and examines fashion expression methods and techniques. This study combines theoretical research and case analysis to analyze the aesthetic characteristics of neo-deconstructivist fashion and the expressive characteristics of neo-deconstructivist fashion. Through analysis of previous research, the aesthetic characteristics of neo-deconstructivism were derived as inclusiveness, playfulness, communication, and intertextuality. Inclusivity in fashion refers to including various people, body types, aesthetics, and cultural backgrounds in the scope of design, and does not limit the scope of clothing design based on individual differences such as body type or gender. Playfulness is a neo-deconstructive fashion brand that combines exaggerated makeup, vibrant colors, intriguing designs, and imaginative fashion shows to spread upbeat and playful ideas. Communication in neo-deconstructivist fashion demonstrates communication through the use of creative themes and items that reflect consumers' needs through design and the consumer's fashion presentation method. Through the mutual quotation of aspects like traits, status, T.P.O., and materials that can reveal opposing texts, intertextuality emerged as a tendency to break up binary oppositions or break away from genres. The expressive qualities of neo-deconstructivist fashion design were examined and applied to the creation of innovative fashion design through examination of the case's silhouette, color, and material. Six sets of women's clothing were designed and produced. The results of this study can be used as basic data for the development of neo-deconstructivist fashion design, and are expected to provide a wide range of inspiration for fashion design ideas.

With development of digital technology and build-up of global network in the 21st century, Korea has recklessly accepted Western information and culture in recent years, thus causing damages to out identity. In the situation, restoration and development of traditions in a modern way will contribute to the creation of contemporary interiors. This study has analyzed and assessed the process through which traditional decorative elements have applied to contemporary interior decorations over the past ten years with a view to identify the trend of expressing traditional elements in comtemporary interiors. Designs that have applied traditional elements in a transfigure expression method amounted to 77 pieces, accounting for $43\%$ of the total investigated 178 designs, which was followed by 48 designs ($27\%$) of metaphor expression method and 39 designs ($22\%$) of symbol expression method, which express the tradition as interpreted by the designer. Designs that have adopted direct expression method amounted to no more than 14 pieces, accounting only for $8\%$ of the total designs. This result suggests that transformative, metaphoric and symbolic expressions that simplify or transform the original forms we more frequently used In the applications of traditional elements to modern interiors rather than directive expression that reproduces the original form as it was.

The purpose of this study was to investigate a comparison between method of depaysement of Surrealism and modern costume. Surrealism was based on Freud's theory of uncon\ulcornersciousness and Hegelian dialectic. I found that its method of expression and inspiration have a continuous influence on a field of fashion through preceding study. Surrealism stimulated Elsa Schiaparelli (1890-1973) to make creative and innovative costume which created a sensatio.i1 the world of fashion in 1930. And it have been influence on modern fashion. From this point of view, I examined surrealistic painter of Rene Magritte (1898-1967) to use shocking method of depaysement through literature and photographes. And I made researches on Paris London collcetions from 1989 to 1994 in the cause of analysis a comparison with depaysement in painting of R. Magritte. As the result of analysising main works of R.Magritte according classification of Suzi Gabric (an art critic), he was expressive of usual object in various of depaysement. I also proved that modern fashion which was new shocking, innovative and avant-garde presented unconsciousness through these expression of depaysement with common subject. In consequence, the method of expression of surrealism have been a durable influence on modern costume.

According to the computerization of railway signaling systems, the interface link between the signaling systems has been replaced by the digital communication channel. At the same time, the importance of the communication link is more pronounced than in the past. In this paper, new network-based protocol for Korean railway signaling has designed between CTC and SCADA system, and the overview of designed protocol is briefly represented. Using the informal method for specifying the communication protocol, a little ambiguity may be contained in the protocol. To clear the ambiguity contained in the designed protocol, we use LTS model to design the protocol for this interface link between CTC and SCADA, the LTS is an intermediate model for encoding the operational behavior of processes. And then, we verify automatically and formally the safety and the liveness properties through the model checking method. Especially, the modal ${\mu}$-calculus, which is a highly expressive method of temporal logic that has been applied to the model checking method. It will be expected to increase the safety, reliability and efficiency of maintenance of the signaling systems by using the designed protocol for railway signaling in Korea.

As a very important part in development of the protocol, verifications for developed protocol specification are complementary techniques that are used to increase the level of confidence in the system functions by their specifications. Using the informal method for specifying the protocol, some ambiguity may be contained therein. This indwelling ambiguity in control systems can cause the occurrence of accidents, especially in the case of safety-critical systems. To clear the vagueness contained in the designed protocol, we use the LTS (Labeled Transition System) model to design the protocol for railway signaling. And then, we verify the safety and the liveness properties formally through the model checking method. The modal ${\mu}$-calculus, which is an expressive method of temporal logic, has been applied to the model checking method. We verify the safety and liveness properties of Korean standard protocol for railway signaling systems. To perform automatic verification of the safety and liveness properties of the designed protocol, a communication verification tool is implemented. The developed tools are implemented by C++ language under Windows XP. It is expected to increase the safety and reliability of communication protocol for signaling systems by using the developed communication verification tool.
