The provision of support for the art of making these items needs to be considered with the focus on the following factors: the local situation of the areas where such traditional handicrafts are still made, the craftspeople involved in their production, and their communities. So far, discussion about how to reinvigorate traditional handicrafts, including those mentioned above, has been concentrated on the measures taken to promote them as part of the handicrafts industry and the allocation of the government's budget for important intangible cultural heritages. The government runs a traditional handicrafts management system and provides financial support for the craftspeople and spaces for exhibiting their work. This form of support has led to systematic management of traditional handicrafts and heightened public interest in cultural heritage, as well as publicizing the country's traditional crafts, but has made little progress in the following areas: the fostering of young people willing to learn traditional skills, diversification of the types of skills to be maintained, or establishment of the networks of collaboration among the craftspeople. The most important aspect among the efforts mentioned above is to maintain cultural traditions that are unique to each region by encouraging local craftspeople to engage in their work with a solid sense of pride backed up by financial support. This study was carried out in connection with the need to reinvigorate the art of making tanggeon (horsehair crown), manggeon (horsehair headband), and gat (black horsehair hat), which few people wear as they are used only for ornamental purposes nowadays. This study examined the circumstances surrounding the artisans engaged in the production of horsehair handicrafts prior to their designation as a cultural heritage, and the changes that occurred in the local communities associated with their production after the designation, in order to assess the status of inheritance of this tradition.

Titanium alloys have lightness, high strength and good corrosion resistant characteristics, and broadly used in manufacturing parts for military and aerospace industries. And these alloys also are recognized for organism materials comparatively and used as fixing ones in the human body. Nevertheless thess alloys have excellent properties such as corrosion resistance, heat resistance, and good tensile strength, it is difficult to machine by traditional methods because of high hardness and chemically activated property. So higher tool wear is expected when cutting by tools. Therefore, it is required nontraditional machining process. And the mechanical characteristics such as surface structure and shape, hardness and bending strength are studied for wire electrical discharge machined and surface ground titanium alloys for various heat-treated conditions.

This paper reports on a study of the morphological design trends and characteristics of vests in contemporary fashion for women. A review of the relevant literature was conducted, and visual images found in various collections displayed in local and foreign papers and on internet web sites over the period 2001 to 2009 were analysed. The analysis of the vest designs showed that 78% had no collar, 41.8% were waist-length, 70.5% used general fabrics of various colors and patterns, 98.2% had a single fastening system, 69.8% used buttons for fastening, and 67.4% were intended to be worn as outwear over inner wear items such as a shirt or blouse. The trends in vest design were characterized by the expression of an androgynous image, by creative diversity and by an escape from traditional forms.

In the manufacturing field, some traditional manufacturing and machining methods become weakened the productivity, the external competitive power, and accuracies of the products. In these point of view, the unmanned and intelligent manufacturing systems are proposed by some manufacturing companies. The real-time monitoring technology of the cutting tool conditions i.e. tool wear, tool breakage, crack, and chipping anre necessarily reauired to realize those system, especially. In this study, we constructed the multi- sensing system using the acceleration sensor, the current sensor, and the loadmeter of a machine tool. Also, we analyzed the nose breakage, the massive signal, and some monitoring features by means of the developed system.

Today's manufacturing industry is facing challenges from advanced difficult-to-machine materials (WC-Co alloys, ceramics, and composites), stringent design requirements (high precision, complex shapes, and high surface quality), and machining costs. Advanced materials play an increasingly important role in modem manufacturing industries, especially, in aircraft, automobile, tool, die and mold making industries. The greatly-improved thermal, chemical, and mechanical properties of the material (such as improved strength, heat resistance, wear resistance, and corrosion resistance), while having yielded enormous economic benefits to manufacturing industries through improved product performance and product design, are making traditional machining processes unable to machine them or unable to machine them economically. In this paper, mechanical characteristic evaluation test of fine powder type WC-Co alloy was accomplished to obtain clear data for miniaturized special die parts machining with high reliability and high quality.

Rental services have recently come to be provided in which people can experience traditional Korean culture in the form of Hanok villages, allowing everyone can easily rent and wear hanbok, a traditional Korean garment, regardless of gender and age. Users of hanbok rental services share photos of themselves wearing hanbok on social media, contributing to the increasing popularity of hanbok experiences. However, the trend of wearing hanbok has no become established in people's daily lives, apart from the specific places that offer hanbok experiences. To promote hanbok as everyday clothes, hanbok design should be developed to provide wearers with both convenience and emotional satisfaction. Using 28 emotion words that express consumers' emotions toward hanbok that were extracted from previous studies, this study measured consumers' emotions toward different types of hanbok with on a seven-point Likert scale. Emotion words and categories that obtained scores of five points or above, signifying a rating of "felt fairly" or higher in relation to specific hanbok types were extracted. This study also examined differences in the average scores for emotional categories according to hanbok types and gender. The results indicated that only average scores for the "favorable feeling" category showed a significant difference between men and women. Finally, differences in the average scores for emotional categories were examined by classifying hanbok types: traditional (e.g., baenaet-jeogori, saekdong-jeogori, traditional hanbok for adults, and traditional wedding clothes) and modern (e.g., daily hanbok for children, for women, and for men). The results indicated significant differences between traditional and modern hanbok in six emotional categories (i.e., the cheerful, esthetic, harmonious, fresh, favorable, and stable feeling). This study derived analytic results for terms related to emotions that hanbok wearers feel according to types of hanbok. The findings can be used by hanbok retailers and rental services to provide consumers with greater emotional satisfaction.

This study analyzed Korean middle-aged men's fashionable styles according to ageless trends as their representative characteristic and deriving their special features from men's magazines. Literature and case studies were conducted together. The research findings are as follows. First, it showed uniformity, conformity, passive clothing selection and consumption in 1990s as characteristics of middle-aged men's wear by period. However, clothing became an expressive way to pursue individuality and an ageless trend gradually, and middle-aged men positioned themselves as subjects of a consumer market for men's wear after 2010 through active clothing selection and consumption. Second, along with a trend change preferring a comfortable and active to formal atmosphere, it showed that casual style became diversified and segmented gradually in Korean middle-aged men's ageless trend and fashionable style. Third, as for formative characteristic changes in middle-aged men's fashionable style by period, it contained a slim silhouette, bright and splendid colors and patterns, increase of light, active and functional materials, generalization of casual items and pursuit of individuality by various mix & match styles. Fourth, in Korean men's ageless trend and changing fashionable style, four kinds of special characteristics were derived that included a change of the traditional clothing symbolism, weakened conformity & pursuit of personality, obscured boundaries between age and wearing style, and active embracing of a trend.

Interest in traditional culture has been increasing due to globalization. We need to create fashion items using Korea folk culture like the Hanbok. In this paper, the design development of toddler's pajamas was attempted by using women's Sokgot pants, which were worn by women in Joseon Dynasty period. The study involved a review of literature and an investigation of past relics. Traditional women's Sokgot pants had a 'mu' or 'dang' in the crotch which is called 'the mit' now. The opening of the mit will be used for designing toddler's pajamas. Design suggestions for four styles of toddler's pajamas, which reflect the formative characteristic of women's Sokgot pants, have been created. Research outcomes are as follow: the characteristics of Ran-pants are applied to design 1 and design 2. There have pleats along the waistband of the toddler's pajamas, making the Mu more hidden. Pleats of the waist part are achieved by using an elastic, which also makes the pajamas easier to fit and to wear. The characteristics of Gaedanggo, of which the crotch is opened, are applied to design 3 and design 4. The opened crotch is applied so that toddlers can relieve themselves easily while they are wearing these pajamas. There is also an opening in the centerline of the front Mu in design 4 which gives additional functionality and comfort. This work shows that items of traditional folk dress can be used to make present fashion items.

The aim of this study was comparative analysis of sediment-induced erosion on optimized design and traditional design of Francis runner blade. The analysis was conducted through laboratory experiments in a test rig called Rotating Disc Apparatus. The results showed that the extent of erosion was significantly less in the optimized design when compared based on the material loss. It was observed that the optimized design could reduce sediment erosion by about 14.4% if it was used in place of the reference design for entire duration of the experiment. Based on the observations and results obtained, it has been concluded that the optimization of hydraulic design of blade profile of Francis runner can significantly reduce the effect of sediment-induced erosion.
