  • We propose a sound source localization method using the Head-Related-Transfer-Function (HRTF) to be implemented in a robot platform. In conventional localization methods, the location of a sound source is estimated from the time delays of wave fronts arriving in each microphone standing in an array formation in free-field. In case of a human head this corresponds to Interaural-Time-Delay (ITD) which is simply the time delay of incoming sound waves between the two ears. Although ITD is an excellent sound cue in stimulating a lateral perception on the horizontal plane, confusion is often raised when tracking the sound location from ITD alone because each sound source and its mirror image about the interaural axis share the same ITD. On the other hand, HRTFs associated with a dummy head microphone system or a robot platform with several microphones contain not only the information regarding proper time delays but also phase and magnitude distortions due to diffraction and scattering by the shading object such as the head and body of the platform. As a result, a set of HRTFs for any given platform provides a substantial amount of information as to the whereabouts of the source once proper analysis can be performed. In this study, we introduce new phase and magnitude criteria to be satisfied by a set of output signals from the microphones in order to find the sound source location in accordance with the HRTF database empirically obtained in an anechoic chamber with the given platform. The suggested method is verified through an experiment in a household environment and compared against the conventional method in performance.

  • Futurists objected the existent style, that is the conventional fashion, and took part in these disciplines of fashion to make clothes the instruments being able to represent the individuality. Giacomo Balla and fortunato Depero, pain-ters who in 1915 were to work with Diaghilev's company, were the first to see clothing as a dynamic interfaced between th body and the atmosphere, between physical gestures and the urban context, which could be translated into encounters between forms and colours, volumes and architecture. For them, clothing began to exist as an object and an event, something to be removed from a mainly static conception and made mobile, active. The interaction between movement and clothing was based on the relativity of perception : the appearance and disappearance of the body produced points without dimension or duration which served, as Balla wrote in the Futurist Mnaifesto of Men's Clothing to“renew incessantly the enjoyment and impetuous movement of the body”. The historical achievement in the effort for the reformation of Futurist, Art to Wear. First, for Futurist, clothing is removed from a static conception and focused on dynamics. Second, Balla used asymmetry in men's clothing. Moreover he supposed dynamic men's clothes by using optical intersection. Third, the after image of Chronophotograph represented rapidity. This rhythmic expression is the fore-runner in Optical and Kinetic Art of Visual Art. Fourth, Futurist emphasized flexibility in fashion. They aimed to create‘Clothing Machines’whose parts would interact to aceelerate the real and virtual, inner and outer movement of the human being. Fifth, the variety and short life of cutting skills and colors are focused and‘Fast Substance’in fashion is admitted by Futurists. Futurist concern with clothing was not lim-ited its appearance in terms of cut and colour. What important was also the way it appeared and disappeared according to fashion. It was a“fast substance”, able to reflect rapid, sudden changes of social and aesthetic taste. To reach to the aim of internationalization, Gesamtkunstwerk in our Art to Wear, it is extremely meaningful to examine art fashion which is created under the conception of Gesamtkunstwerk production of avang garde artist in the early 20th century and look at formative conscious of truth, goodess and beauty synthetically which they faced on their works of art.

  • Purpose: The purpose of this study is to develop golf wear textile design, produce simulation and samples, and create original designs using geometric patterns. Significance: If modern people's trend to pursue well-being is be associated with healthy and active lifestyle and the design which combines a sport sense into artistic image appears in golf wear, it is a very significant effort to settle the role of sport as a mega trend. Contents: This study examined the general concept of geometric patterns and the situation and characteristics of women's golf wear. Finally, the design and simulation of gold wear textile were proposed. Study Instruments: For theoretical research, articles, books, literatures, and Internet materials published at home and abroad were reviewed and collected. For empirical research, a dot, a stripe(a line), a square, and an oval were selected and simulation was tested visually after the development of textile designs. Finally it was directly produced and golf wear design was developed. Photoshop CS 3 and Wacom intuos 3 were used as a general-purpose program and hardware respectively. DTP printing was used for sample work. Based on research results, geometric patterns range broadly and diversely from prehistoric remains and relics to contemporary art, design, architecture, and fashion. It is a unique formative element with value and attraction as the infinite object of inquiry beyond an area and the times. The combination of geometric patterns with art touch could complement the rigidity of design. It contributed to the perception of important role of art in the design area, namely, the importance of design containing artistry.

  • This study determines the body size of preteen children and conducts questionnaire investigations into the awareness of real purchasers or parents of and satisfaction with children's clothes and fit, in order to provide the basic data for planning and setting up the size range for the preteens market in which the sales of children clothes are gradually increasing. The findings of this study are as follow: Analyzing the obesity of the children against the Rohrer index showed that almost 30% of the subjects were obese children and that it is necessary to research the sizes of the clothes for obese children. It was also found that older children selected a more appropriate clothe size. Investigations into the awareness of children on their body image found that there was a significant difference in the perception of body shape, body weight, shoulder breath, arm thickness, chest girt, waist girth, hip girth, and thigh thickness. Slim or standard type children had the greatest consideration for the length of clothes to purchase while obese children had the greatest consideration for bosom size and waist girth. However, in terms of the association between fitness and size selection, obese children did not select a bigger size but an appropriate one for their body. The findings show that it is imperative to develop appropriate size clothes for obese children.

  • We live in the era of unlimited design competition. As the importance of design is increasing in all areas including marketing, each country does its best effort on design development. However, the preparation on protecting interior design rights by intellectual property laws(IPLs) has not been enough even though they occupy an important place in the design field. It is not quite easy to make a judgement on the similarity between two images having a single common factor because the factors which are composed of interior design have complicated interactive relations between them. From the IPLs point of view, designs with the similar overall appearance are decided to be similar. Objective evaluation criteria not only for designers but also for design examiners and judges are required in order to protect interior design by the IPLs. The objective of this study is the analysis of the possibility that a computer algorithm method can be useful to decide the similarity of interior design images. According to this study, it is realized that the Img2 which is one of content-based image retrieval computer programs can be utilized to measure the degree of the similarity. The simulation results of three descriptors(CEDD, FCTH, JCD) in the Img2 showed the high degree of similar patterns compared with the results of perceptual judgment by observers. In particular, it was verified that the Img2 has high availability on interior design images with a high score of similarity below 60 which are perceptually judged by observers.

  • Due to the paradigm shift in fashion industry, its contribution to social activities and social enterprises' practice of ethical fashion has been on the rise lately. The surveillance and regulations of international community have increased in light of the betterment of working conditions and protection of the rights, and corporate social responsibility has been emphasized through consumers' interest in ethical consumption. In this regard, the fashion social enterprises' responsible and ethical management can both boost the trust in business and value-added. The study aims to propose feasible methods by exploring ways to induce support from central and local governments, which will lead to the activation of future fashion social enterprises and paradigms shift of consumers's perception and value. The sustainability of social enterprises requires management line or policies that consider social, environmental, economic, and political aspects of virtuous cycle, differentiated internally or externally. Fashion social enterprises also need ethic management and social responsibility management that are distinctive from general fashion enterprises. Thus, they will not be sustainable or differentiated unless entrepreneurial faith and role is not clear. Education and continuous promotion including upcycling are critical to build consumer base as they can make consumers spend ethically and recognize social enterprises. In addition, social education and public relations need to take place in order to internalize consumer pattern. The goal of sustainable corporate social activity is to change the awareness and become social investment that returns some profits to the society as members in line with reviewing corporate image. This can lead to establishing the foundation of securing a big comsumer market and winning the trust of the consumer's through corporate social responsibility and investment.

  • The purpose of this study is to delve into the identity of the New-Hanbok style in modern fashion, and to survey its formative characteristics and internal values from the perspective of vernacular design. Arguments can be summed up as follows. The study historically examines the changes in Hanbok and concludes that the social and cultural backgrounds and factors that caused the advent of the New Hanbok are (1) the change and expansion of the basic social, cultural, and popular perception toward the Korean image, (2) the rapid spread of a subculture centering on the younger generation, and (3) the voluntary and systematic activities of nonprofit clubs, communities and private organizations. This is the cycle of the spread of Hanbok, which shows the subcultural selection and development process of upward propagation. Furthermore, the public, in addition to holding fast to an independent attitude regarding their choices, also show that they tolerate diversity. As a perspective of analyzing the New Hanbok style, the study suggests the characteristics of the vernacular design perspective as (1) a spontaneous indigenous nature (2) living everydayness (3) and the subcultural-ness of the era. From such a perspective, the study examines the formative characteristics of the basic costume configuration of the New Hanbok style including jeogori, traditional Korean skirts, Cheollik one-pieces, and Trompe l'oeil one-pieces, and draws out the meanings contained in the New Hanbok style, which are (1) spontaneous indigenous nature and directivity toward tradition, (2) living everydayness and modernity, and (3) open subcultural-ness.

  • Objective: This qualitative study retrospectively examined the experience and psychological impact of contralateral prophylactic mastectomy (CPM) among Southern Chinese females with unilateral breast cancer history who underwent BRCA1/2 genetic testing. Limited knowledge is available on this topic especially among Asians; therefore, the aim of this study was to acquire insight from Chinese females' subjective perspectives. Methods: A total of 12 semi-structured in-depth interviews, with 11 female BRCA1/BRCA 2 mutated gene carriers and 1 non-carrier with a history of one-sided breast cancer and genetic testing performed by the Hong Kong Hereditary Breast Cancer Family Registry, who subsequently underwent CPM, were assessed using thematic analysis and a Stage Conceptual Model. Breast cancer history, procedures conducted, cosmetic satisfaction, pain, body image and sexuality issues, and cancer risk perception were discussed. Retrieval of medical records using a prospective database was also performed. Results: All participants opted for prophylaxis due to their reservations concerning the efficacy of surveillance and worries of recurrent breast cancer risk. Most participants were satisfied with the overall results and their decision. One-fourth expressed different extents of regrets. Psychological relief and decreased breast cancer risk were stated as major benefits. Spouses' reactions and support were crucial for post-surgery sexual satisfaction and long-term adjustment. Conclusions: Our findings indicate that thorough education on cancer risk and realistic expectations of surgery outcomes are crucial for positive adjustment after CPM. Appropriate genetic counseling and pre-and post-surgery psychological counseling were necessary. This study adds valuable contextual insights into the experiences of living with breast cancer fear and the importance of involving spouses when counseling these patients.

  • Purpose - The purpose of this study is to investigate the factors that cause consumers to frequently visit large - Super Store and goods for large - scale retailers using Super Store. Research design, data, and methodology - The purpose of this study is to present the empirical analysis of 53 adult males and females living in the Mokpo area on the relationship between perceived level of satisfaction and loyalty of the large - scale marts. The results were analyzed. The statistical data of the questionnaire were verified by the SPSS. Results - In the empirical analysis of this study, four variables were found to be the main loyalty factors, which were found to affect the satisfaction of Super Store and the decision to return again. Therefore, in this study, the quality of goods, price, diversity, and image were analyzed as loyalty factors, and it was analyzed as factors influencing satisfaction. It was confirmed that loyalty factors were important. In particular, consumers' perception of behaviors such as local specialties and community service that can be distinctly differentiated from other distribution agencies was very low. Conclusions - It is necessary to construct a comprehensive systematic system to analyze the detailed factors influencing the satisfaction and loyalty of users of Mokpo ticket consumers and to systematically manage and evaluate them. In order to raise awareness of consumer loyalty factors, consumer satisfaction and loyalty survey should be regularly conducted. Consumers should look for ways to improve them and develop improvement plans. The various direct and indirect services provided by Super Store to consumers include price, quality, assortment, customer service, accessibility, and feelings for large marts. However, since the services provided by the Super Store are different from those of the consumers, the loyalty factors for the different factors can be different. Therefore, in order to differentiate them from traditional markets or other distribution centers, it It should be used as a weapon of competition. In this study, it is generally recognized that the services provided by Super Store are very simple and inexpensive, so that consumers are not aware of the difference of particular stores.
