Jazz derived from the blacks' work songs and made the frame of Jazz reaching blues and finally arrived at the recent time propagating itself as not only the blacks' music but all human being's music. This study has a purpose to suggest the Jazz image to the fashion design by examining the historical trace of Jazz which is one of popular music received by hearing sense. As for the result of the Jazz's effects by age, rhythmical beauty stressing dresses were in fashion by dance enjoying women in 1920's and dresses giving a mature atmosphere set the fashion in 1930's. in the beginning of 1990's, newly emerging Jazz was reflected to the popular culture along with the historical mode's fashion in the general society. The design's decided with two themes of Jazz Classic and Neo Fusion to modernly and naturally express the pursuit of strong color contrast which associated fast rhythm and lax image such as the counter melody of smooth Jazz. In that result, Jazz image with auditory feelings could suggest the various design motive and new idea to fashion design.

Viewed as a more systematic approach of creating high quality products and bringing them into market at a lower cost and in significantly less time, it attracts the attention of quality designers to quality function deployment (QFD) approach. In attempt to reduce the design cycle, the industry has responded with concurrent design effort. In a sense, concurrent engineering refers to the integration of various activities within the broad scope of the product life cycle ［17］. Over the last ten years, much has been written about QFD but little has been available in terms of the underlying guide methodology. The methodology of QFD is quite simple and many will say that they have done it in the past but just have not formalized it into the form that this discipline requires. QFD ties the product, user, value, and manufacturing viewpoints together in a continuous process of defining the product design and manufacturing requirements. The value viewpoint recognizes the cost to obtain certain functionality, and the manufacturing viewpoint addresses conformance to requirements, but in a broader sense, the variability in production. In this paper, the QFD system acquisitions are described, and two heuristic approaches solving for the complex design process, especially the size reduction of design process and precedence-constrained relationship in QFD are proposed, and the empirical example is illustrated.

The assessment of an urban site depends on the way whether it responds to multiple needs such as functionality, aesthetic and complex comfort of acoustic, thermal, lighting and air quality etc. This study aims to investigate the assessment of various urban soundscapes in the sense of acoustic amenity by the questionnaires. As a result, acoustic amenity assessment was influenced by the non-acoustic factors such as environment assessment of visual, thermal, air quality etc. In the sense of sound quality, urban environmental sound was interpreted as 3 factors of strength, evolution of time, spacial localization. So these factors would be considered in the new assessment method for acoustic amenity. And it was shown that the subjects tend to perceive the noise level less than $3{\sim}5dB\;L_{eqA}$ according to the urban landscapes under the similar noise exposure level.

In this paper, a temperature controller for a semiconductor test handler is proposed. First, a handware system for identification and control is established using RTD sensors, an A/D converter, solid state relays, a heater, and a computer system. Second, using ARMAX model and least square method, a chamber model for the design of a controller is identified through experiments. The identified model is verified to describe the real plant very well in the sense that it shows very similar input-output responses to those of the real system. With the identified model an LQG controller is designed. Frequency response of the designed controller shows that it has 15 dB of gainmargin and (-50˚, +50˚) of phase margin. Experiment with a real test handler demonstrates a good performance in the sense that its overshoot and steady state error are smaller and response time is faster, compared with those of a conventional PID controller.

The purpose of this study was to understanding the intrinsic meanings and aesthetic characteristics expressed by current fashion trends in neckties and to develop a new and unique fashion design for neckties. This study used precedent studies and related literatures to review the changes in neckties and the types of knots used over time. The findings were then verified by photographs from fashion magazines and collections from the 1990s. The results of this study are as follows. First, neckties, generally regarded as a symbol of masculinity, are often mixed with other men's or women's clothing items rather than being worn by themselves, and they provide an androgynous characteristic in women's fashion. This transcendence of femininity or masculinity reflects the human desire to be a more perfect being by sharing each others characteristics, and it can be seen in contemporary beauty trends. Second, neckties have been transformed into scarves, waist belts, front-fly omaments, and so forth. They are used to express a new and sensational sense, the sense of deconstructionism, by breaking away from stereotypes and changing the shape of neckties atypically.

This paper deals with the optimal filtering problem constrained to input noise signal corrupting the measurement output for linear discrete-time systems. The transfer matrix H$_2$and/or H$_{\infty}$ norms are used as criteria in an estimation error sense. In this paper, the mixed $H_2/H_{\infty}$ filtering Problem in lineal discrete-time systems is solved using the LMI approach, yielding a compromise between the H$_2$and H$_{\infty}$ filter designs. This filter design problems we formulated in a convex optimization framework using linear matrix inequalities. A numerical example is presented.

A quantitative evaluation of postural balance training using a virtual reality bicycle system was performed. In the experiment, the effectiveness of virtual reality bicycle system on postural balance training was analyzed with four male subjects in their twenties. The parameters measured during cycling were cycling time, average velocity, number of times subject deviated from path, and weight shift. Those parameters were evaluated for the quantification of the extent of control. We also measured the parameters on postural control capability after 5th trial and 10th trial in a balance testing system with a force plate to find out the effectiveness of the training. In the balance test with force plate, it was found out that the weight shift was almost zero and the deviation from the target trace reduced significantly after the training with the virtual cycle. The result showed that the virtual bicycle system was an effective system as a rehabilitation training device.

The field of brain science (or neuroscience in a broader sense) has inspired researchers in artificial intelligence (AI) for a long time. The outcomes of neuroscience such as Hebb's rule had profound effects on the early AI models, and the models have developed to become the current state-of-the-art artificial neural networks. However, the recent progress in AI led by deep learning architectures is mainly due to elaborate mathematical methods and the rapid growth of computing power rather than neuroscientific inspiration. Meanwhile, major limitations such as opacity, lack of common sense, narrowness, and brittleness have not been thoroughly resolved. To address those problems, many AI researchers turn their attention to neuroscience to get insights and inspirations again. Biologically plausible neural networks, spiking neural networks, and connectome-based networks exemplify such neuroscience-inspired approaches. In addition, the more recent field of brain network analysis is unveiling complex brain mechanisms by handling the brain as dynamic graph models. We argue that the progress toward the human-level AI, which is the goal of AI, can be accelerated by leveraging the novel findings of the human brain network.

This study is planned to help women in international marriages to develop their sense of self-esteem and their family life and to adapt to Korean society, The findings are as follows: First, the women in international marriage tend to have low self-esteem and difficulty to adapt themselves to the society due to language barrier, cultural conflicts, sense of alienation, isolation and so on. however, now they seem to have the strength of mind by themselves, to accept other people and to adapt to the society better than before the education program by having had communications with the program members and their allied mothers in the program. Second, the cohesion among the program members per session has improved over the sessions, and the members' interest in the education program has increased. moreover, the members have opened up themselves over time. Third, the alliances with Korean teachers as their allied mothers not only helped their Korean but also taught the members about family life. It helped the members to adjust to their family life and became a mental support.
