The culture phenomenon, which the desire of self expression is noticeable and the diversity of gender identity is widely accepted, simply makes a difference in the lifestyle of one human being rather than the dichotomous classification of male and female. Now, the delicate and aesthetic sensitivity classified as the feminine characteristics is no longer the exclusive property of female and this refers to substituting it as a social gender from the concept of biological sex. This phenomenon has influenced on the male culture and is creating various codes according to the cultural gender extended from the gender as a social role. Also, the transition into the western lifestyle has extended the aesthetic emotion to accommodate new codes from the diversification and globalization of lifestyle. The mansumer power, which does not care too much about the money for the emotionally attached items, has enabled various fashion styles. After analyzing the diversified clothing behavior conducted by these people in connection with the social phenomenon, First, this shows the phenomenon of emotional value pursuit that finds pleasure over the clothing as the item of augmented reality is added to the concept of play, in which the real space referred to as garment and virtual space of playing the rock, paper and scissors game meet together within the augmented reality. Second, the convergence concept has enabled the coordination of new style by obscuring the area of design concept and this refers to the changes in design from the development of new items and transformation into double-style details. Third, the divergence that intensively provides specific use/convenience and specialized value shows a change in the fashion market from the phenomenon that admits various gene rations of culture and specifically, takes differently about the recognition of middle-aged males. Fourth, the variety seeking tendency receives attention as the value of future design together with the phenomenon of discriminative value pursuit. In the male fashion, it is linked to the collaboration with the design area and this tells that the fashion with the narcissistic cross-dressing and motto of neutral gender without being sided to male/female is rising.

Conventional paints for conversion coating applications in steel production derived mainly from water-based polymer dispersions containing several additives actually show good general performance, but suffer from poor scratch and abrasion resistance during use. The reason for this is because the relatively soft organic binder matrix dominates the mechanical surface properties. In order to maintain the high quality and decorative function of coated steel sheets, the mechanical performance of the surface needs to be improved significantly. In fact the wear resistance should be enhanced without affecting the optical appearance of the coatings by using appropriate nanoparticulate additives. In this direction, nanocomposite coating compositions (Nanomer$^{(R)}$) have been derived from water-based polymer dispersions with an increasing amount of surface-modified nanoparticles in aqueous dispersion in order to monitor the effect of degree of filling with rigid nanoparticles. The surface of nanoparticles has been modified for optimum compatibility with the polymer matrix in order to achieve homogeneous nanoparticle dispersion over the matrix. This approach has been extended in such a way that a more expanded hybrid network has been condensed on the nanoparticle surface by a hydrolytic condensation reaction in addition to the quasi-monolayer type small molecular surface modification. It was expected that this additional modification will lead to more intensive cross-linking in coating systems resulting in further improved scratch-resistance compared to simple addition of nanoparticles with quasi-monolayer surface modification. The resulting compositions have been coated on zinc-galvanized steel and cured. The wear resistance and the corrosion protection of the modified coating systems have been tested in dependence on the compositional change, the type of surface modification as well as the mixing conditions with different shear forces. It has been found out that for loading levels up to 50 wt.-% nanoparticles, the mechanical wear resistance remains almost unaffected compared to the unmodified resin. In addition, the corrosion resistance remained unaffected even after $180^{\circ}$ bending test showing that the flexibility of coating was not decreased by nanoparticle addition. Electron microscopy showed that the inorganic nanoparticles do not penetrate into the organic resin droplets during the mixing process but rather formed agglomerates outside the polymer droplet phase resulting in quite moderate cross linking while curing, because of viscosity. The proposed mechanisms of composite formation and cross linking could explain the poor effect regarding improvement of mechanical wear resistance and help to set up new synthesis strategies for improved nanocomposite morphologies, which should provide increased wear resistance.

This study intends to analyze the up-cycling trend that is attracting great attention these days and its internal meaning in the context of fashion art. And, based on this, to provide enhanced value and creativity in the future fashion artwork and design businesses, keeping abreast of further fashion art developments. As part of the study methodology, both a literature review and a case study were carried out, along with an examination of up-cycling and research into related pictures and content. The materials covered in this work include design and fashion related books and domestic and foreign magazines from 2000 to 2011, when the up-cycling movement was initiated as a form of eco-friendly design. For the analysis of fashion art pieces, generic terms included art wear, wearable art wear, and unwearable art. Case review was followed by the works of artists shaping their fashion concept and meaning entirely from abandoned clothes and fabrics, waste materials, and their art collection. Consequently, key elements of the value of up-cycling fashion art are that it is eco-friendly, has a unique identity, and reflects multi-dimensionalism. This research saw the integration of fashion with other variables, artistic attributes, and reuse of resources. This could lead to a new realm where value-addition is formed and extended, thus providing another chance for the fashion industry.

The occurrence and pattern of tooth wear are related to cultural, dietary, occupational, and geographic factors, Excessive occlusal wear can result in pulpal exposure, occlusal disharmony, functional inability. Surface loss can be differentiated into 3 general causal categories: i) mechanical loss, which includes attrition, ii) abrasion chemical loss including erosion, and finally iii) a proposed biomechanical category described as abfraction. Considering that mechanical wear is frequently asymptomatic, patients may have parafunctional habit. Structured clinical decision analysis in fixed prosthodontics, as other branches of dentistry do, allows the practitioner to consider the patient's problems more thoroughly based on the clinical data and extenuation factors. This discipline of decision making is intended to complement the experience level and educational background of the clinician in assisting the patient through the decision process. Additionally, CDA helps the clinician define not only the pre-existing condition of the patient prior to irreversible therapy, but also better treatment strategies for the patient over an extended period. The systematic nature of decision analysis stimulates the dentists to pay further attention to those factors, which is germane to the overall complexity of the case, and exclude factors, which have little influence on its final outcome. Further implementation of computerized databases, procedural outcome probabilities based on clinical and laboratory studies and the clinical experience of those who use it, may provide quite a promising future in the field of structured and formalized clinical decision analysis.

This study identified domestic and foreign golf clothing norms and extended recognition and attitude on golf clothing norms expressed in a golf wear style for golfer groups in their 20s-30s. Domestic golf clothing norms were derived from a theoretical research and case study; subsequently, golfers in their 20s-30s were classified into 4 groups. In-depth interviews were conducted using a serious leisure concept to analyze attitudes and stylistic expressions. Domestic golf clothing norms derived from stipulated and implicit norms varied as a type and situation of a golf course, gender of the golfer, and domestic golfers in their 20s-30s perceived such a point. For golfers in their 20s-30s, attitudes on golf clothing norms and their stylistic expressions showed differences according to gender and leisure type. As for gender characteristics, female golfers focused on 'look prettier' in stylistic expressions through experiences with a double-standard clothing norm; however, male golfers showed strict application and observance of a clothing norm in stylistic expressions compared to female golfers. However, male golfer groups in their 20s-30s as 'casual leisure participants' and those as 'serious leisure participants' showed differences becuase the former showed a tendency to observe clothing norms from other viewpoints and evaluations and the latter showed off their abilities and careers as a means of distinction. As for characteristic of stylistic expressions according to a leisure type, golfers in their 20s-30s showed distinction as serious leisure participants through forming new and independent clothing norms. Research findings are expected to provide an opportunity to reconsidering the influence of clothing norms in young people who have a strong tendency to express clothing style as a means to pursue individuality and taste.

This study examined personal protective clothing, specifically the D (M, L, XL) and C (L, XL, 2XL) levels with high sales rates. The goal was to collect essential data for developing Korean personal protective clothing. There were eight and twelve patterns for the D-level and C-level, respectively. While the pattern dimensions were similar, the chest and waist circumferences (relaxed) were larger in the C-level, and the waist (extended), hip, upper arm circumference, and total lengths were larger in the D-level. The D-level wear sensation worked well for average-sized Koreans in their twenties, but the C-level caused discomfort in multiple areas, such as the face, arms, armpits, hips, crotch, thighs, and knee during movement. Consequently, this region required pattern adjustments and resetting for improved comfort. The grading rules were 10 cm in the chest, waist, and hip circumference, regardless of the level, with slight differences in other parts depending on the levels. Thus, manufacturers should establish new grading rules to suit the Korean body shape.

Fashion appears as a similar sense of form in a regularly cyclical way. The part highlighted in the female body also becomes that way. The social and cultural problem of fashion is also a matter about the selection of a wearer on how to wear in what environment. Power dressing means an attire that makes you feel dignity, intelligence or power and an attire that is needed to succeed in the business society. It is based on the fact that women started wearing tailored suits that were regarded as the exclusive item of men as the women's social activity was actively progressing. The purpose of the study is to analyze the problem of styles in the social and cultural perspectives. The power dressing was repeatedly appeared in 1930s, 1980s and 2000s. Therefore, this study collected photo data and literature documents to analyze and compare shoulders represented during these three periods, and to examine what social cultural environment was operated for each period and how the designers of each period expressed with clothes. Power dressing is characterized by the use of shoulder pad for the first time for 1930s, the extended shoulder for 1980s and the design the extended shoulder with the more decorative method for 2000s. Power dressing has been utilized as women's gain and improvement of social status, flaunting of economical status and a symbol of individuality and identity.

Purpose: This study was to compare the habitual soft contact lens wear to recommended wearing schedule for subjects and suggest a clinical guideline for prescribing contact lens. Methods: 611 adults (39 men and 572 women) with contact lens experience took part in this study. The survey collected information about current wearing schedule (hours/day and days/week), types of lenses worn and awareness of recommended wear schedule. Results: The subjects wore the daily contact lens for $7.97{\pm}3.60$ hours/day in average. Of these, 247 subjects (40.4%) exceeded the recommended wear schedule and 36 (5.9%) wore for over 15 hours. It turned out that subjects with 3-month extended contact lenses and the ones with the conventional daily wear wore for $9.79{\pm}2.68$ hours and $8.98{\pm}3.30$ hours/day, respectively. For subjects wearing contact lenses longer than five days/week it tended to wear for over 9 hours. Those who were aware of the wear schedule were 293 (48.0%), and those not were 318 (52.0%). 56.7% of subjects who were aware of the wear schedule respected the recommendation whereas only 22.3% of those unaware of it were found to respect it. The possibility to respect the wear schedule was 4.55 times higher when wearers were aware of it. Conclusions: Korean office workers wearing contact lenses wore for $7.97{\pm}3.60$ hours/day. 247 (40.4%) of subjects wore contact lens longer than recommended wear schedule. This implies that it will need to educate contact lens wearer about recommended wear schedule and advice for the long time wearer.

An experimental modeling of cutting and structural dynamics and the on-line detection of malfunction process is substantial not only for the investigation of the static and dynamic characteristics of cutting process but also for the analytic realization of diagnostic systems. In this regard, We have discussed on the comparative assessment of two recursive time series modeling algorithms that can represent the machining process and detect the abnormal machining behaviors in precision round shape machining such as turning, drilling and boring in mold and die making. In this study, simulation and experimental work were performed to show the malfunctioned behaviors. For this purpose, two new recursive approach (REIVM, RLSM) were adopted fur the on-line system identification and monitoring of a machining process, we can apply these new algorithm in real process for the detection of abnormal machining behaviors such as chipping, chatter, wear and round shape lobe waviness.

The sintered parts are mainly used for automobile industry, and a part of air conditioners. In automobile industry, the application range of sintered parts is very broad and use for a driving and a lubricating system. And air conditioner uses them for compressor. Grinding of compressor and pump parts is very difficult these days, because these parts use High hardness materials and require high precision grinding. Tool life has to be extended to decrease production cost. We analyzed processing mechanism and developed new grinding wheels for Double Disk Grinding. And, we introduce new truing technology that improved tool-life and precision.
