Modern fashion can be expressed as 'pursuit of cocktail effect', which means not unformed, not bounded by a rule, and mixed with various styles. Among them, the most outstanding trend of style is the'infra-syndrome'which designs underclothes like a ordinary wear, which has outstood since early 1980s. In 1990s, this syndrome made active progress and now facing 21th century, it becomes one of the big trends in fashion. Clothes of infra syndrome are one of attempts for freedom expressed by progressive designers who pursuit new and surrealistic design. The purpose of this study is to maximize the aesthetic beauty of'infra-syndrome'apparel centering on dresses of which designs are notable derived from underclothes. With the sewing techniques using the special facilities of the lingerie-manufacturing industry and making use of new material which can be used far lingerie wear, this research strives to expand new ideas in the lingerie industry as well as to contribute to promoting the dress culture by developing novel lines from a new form of dress and lingerie-foundations of dress suitable for human body.

The clinical application of aligners is accompanied by the ageing of the polymer appliances and the attachments used, which may result in inefficiency in reaching the predicted range of tooth movement, and release of compounds and microplastics in the oral cavity as a result of the friction, wear and attrition of the aligner and composite attachment. The purpose of this review is to present the mechanism and effects of in vivo ageing; describe the hydrolytic degradation of aligners and enzymatic degradation of composite attachments; examine the ageing pattern of aligners in vivo, under actual clinical scenarios; and identify a link to the discrepancy between predicted and actual clinical outcome. Lastly, strategies to deal with three potentially critical issues associated with the use of aligners, namely the necessity of weekly renewal, the dissimilar mechanical properties of aligner and attachment resulting in wear and plastic deformation of the aligner, and the development of integuments and biofilms with microbial colonization of the appliance, are discussed.

Studying awareness, importance, satisfaction, and wearing behavior of functional textiles for active silver generation related with gender and age is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, silver generation considered all the clothing comfort sensations important when wearing clothes, such as tactile sensation, clothing pressure sensation, thermal/wet sensation, and motion sensation in human physiological aspect. Also, stretchy fabrics were ranked first in awareness, the number of wearing times, and satisfaction of comfort functional fabrics. More than 30% of silver generation have fifteen items out of 36 functional clothes. Second, in analysis of awareness by gender on functional clothing products, women were more aware of health/safety-oriented fabrics than men were. Otherwise, men had more knowledge about the water-related properties of functional fabrics than women have, such as water/moisture absorptive and water-repellent/vapor permeable fabrics. While women have more indoor casual wear, men had more active sportswear. Also, women expressed a strong preference to the stretchy function of fabrics.

Martensitic stainless steel STS 431 has been nitrided by active screen ion nitriding under the various temperature and time. The thickness of diffusion layer, case depth, hardness and composition phases were investigated using field emission scanning electron microscopy (FE-SEM), micro-Vickers hardness tester, X-ray diffraction (XRD) and glow discharge spectroscopy (GDS). It was observed that the thickness of diffusion layer depends strongly on the treatment temperature and time. A sample, which was nitrided at $450^{\circ}C$ for 8hours, was a maximum hardness of Hv0.01 1558 and nitride layer of $70{\mu}m$. As shown in XRD patterns, $\varepsilon(Fe_{2-3}N)$ and expanded martensite (${\alpha}_N$) phases which was saturated with nitrogen solid solution were in the nitrided layer treated at $450^{\circ}C$ for 2 hours. Composition phases of $\varepsilon$ $(Fe_{2-3}N)$ and ${\gamma}'$ ($Fe_4N$) were observed after active screen nitriding at $450^{\circ}C$ for 8 hours.

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.

Understanding awareness and wearing behavior of functional textiles for silver generation is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, the level of awareness for both comfort-oriented and health/safetyoriented functional fabrics in high health-conscious group was much higher than that in low health-conscious group. In number of wearing times, health body and high-conscious group wear comfort-oriented fabrics more frequently, while weak body group wear health/safety-oriented fabrics more often. The health-consciousness significantly influenced the possession of active sportswear with various functions. Second, the awareness of functional fabrics in exercise activities groups was much higher than that in exercise-conscious groups. High exercise activities group know more about the wet sensation-related fabrics and clothing materials for outdoor activities. Low exercise-conscious group put on health/comfort-oriented fabrics for casuals more frequent than functional fabrics for sportswear. High exercise activities group preferred to wear sportswear suitable for outdoor activities. The aged people have a lot of health/comfort-oriented functional casual wear appropriate for indoor activities regardless of exercise-consciousness. However, the more they enjoy exercise activities the more they are interested in functional sportswear. Even though they were unconcerned with exercise, older people are interested in functional casual clothes. As a conclusion, the high interest in health and exuberant activities in silver generation arose the necessity of new multi-functional clothing products.

The service life of tools in metal forming technology is to a large extent limited by wear and fatigue fracture of the active elements. This presents a basic request for tool cost minimization and reduction of extensive machine down time, caused by premature tool failure. Currents developments are dominated by steps to reduce the causes of tool failure. A main problem of forming technology remains the insufficient reliability of tools due to a large and incalculable life time fluctuation. Only a systematic investigation of the failure mechanisms and operational loading of tools can lead to future improvements in tool layout, that is optimization of tool usage.
