The purpose of this study is to design fashion-cultural products by reviewing the symbolism in Changseung and Sotdae, which are folk belief sculptures. This study was performed by literature reviews of Changseung and Sotdae in order to look into the characteristics of folk belief and traditional culture, and the designs were developed from the symbolism extracted from Changseung and Sotdae with photoshop CS5 and illustrator CS5. The Symbolism of Changseung and Sotdae were as follows: First, Changseung and Sotdae express the 'symbiotic world view' that human beings need to devote one's life to nature. Second, original materials were saved in order to achieve the 'pursuit of essence'. Third, 'simple esthetic expression' was symbolized through the undivided condition between art, religion and life. And fourth, 'empathic humor' was seen through the basis of emotional sense of affinity. The first concept of design development was 'Pursuit of Essence', which was inspired by the characteristics of 'symbiotic world view' and 'pursuit of essence'. Changseungs were expressed as simple and abstract, and Sotdaes as simplified and modern by symmetrical and rotating copy. The second concept, 'Touch of Humor' was inspired by 'simple esthetic expression' and 'emphatic humor'. The face of Changseungs was exaggerated in a humorous ways and Sotdae was developed as sub-motives. The items for the fashion-cultural design were T-shirts, bags, and scarves. Total of 24 items were developed with 4 differently styled designs for each concept. This study was based on basic culture and attempted to diversify the traditional culture items. It hopes to raise the value of traditional culture, and furthermore help build up national competitiveness.

This study investigates the apparel sizing communication presented in online retail websites focusing on women's ready-to-wear tailored jackets and to analyze the meaning of these information as the actual product size guide factor. A total of 34 retail websites were selected based on the highest growth fashion companies list and the best fashion brands list. We collected size information in two types: size specifications including sizing code, body measurements, garment measurements, and size references including customized size guide tools, size information in customer reviews, model size information, and others. Most websites prefer to present garment measurements rather than body measurements that are recommended notations under Korean standards and related regulations. In addition, there was the absence of consistency in presenting measurements list and terms that can confuse consumers in size communication. This study found that the stature measurement was a key factor in size reference despite that it did not represent a proper garment size. The obsolete Korean numbering sizing code such as '55 and '66 was still used in many ways such as idiomatic expressions for body shape. It also implied that we can take advantage of the old sizing code for accessible size information. The finding of this study gives an in-depth diagnosis of current online sizing information problems and suggests useful basic data for developing online apparel size standards and marketing strategies.

Cheese is an excellent substrate for yeast and mold growth. These organisms can cause cheese spoilage, resulting in significant food wastage and economic losses. In the context of cheese spoilage, the presence and effects of spoilage or pathogenic bacteria are well documented. In contrast, although yeasts and molds are responsible for much dairy food wastage, only a few studies have examined the diversity of spoilage fungi. This article reviews the spoilage yeasts and molds affecting cheeses in various countries. The diversity and number of fungi present were found to depend on the type of cheese. Important fungi growing on cheese include Candida spp., Galactomyces spp., Debaryomyces spp., Yarrowia spp., Penicillium spp., Aspergillus spp., Cladosporium spp., Geotrichum spp., Mucor spp., and Trichoderma spp.. In addition, several mold spoilage species, such as Aspergillus spp. and Penicillium spp., are able to produce mycotoxins, which may also be toxic to humans. There are many ways to eliminate or reduce toxin levels in foods and feeds. However, the best way to avoid mycotoxins in cheese is to prevent mold contamination since there are limitations to mold degradation or detoxifications in cheese. Chemical preservatives, natural products, and modified atmosphere packaging have been used to prevent or delay mold spoilage and improve product shelf life and food safety.

In recognition of the transportation problems of the present and to prepare for the ever increasing demands of the future, government decided to develop the magnetically levitated train domestically and started R&D program office in Korea Institute of Machinery and Metals(KIMM). This office since has established three step by step goals : first to develop a 40 passenger exhibition vehicle for Daejon EXPO'93, second to develop the low to mid-speed maglev system for urban public transportation by 1997 and finally the high speed inter-city maglev train by year 2001. The first two maglev systems will use attractive levitation-LIM driven technologies and these technologies are the ones currently being developed by this office and others. The maglev train system is a product of wide range of technologies from electro-technologies to civil engineering technologies. Some of the technologies are currently available but more have to be developed in the near future and these technologies are owned by or to be developed by various institutions within the science & technology community. The level of the technologies available at the present time are still very rudimentary and their basis are very narrow. Recently we have made a few successes in terms of levitation and propulsion but they are only with small scale modules and results are very qualitative at best. A great deal of development work has yet to be done to refine the technologies and to gain confidence. Full scale levitation/propulsion modules will be tested on the curved guideway within 6 months by this office and another institution. This paper reviews the current status of the maglev technologies in Korea and discuss the development strategies. The Korean maglev program is very ambitious and the schedule is even more so. A steady financial support and strong system engineering and integration are essential to the success of this program.

This study aims to suggest a direction for interior space design for fashion flagship stores in the future where the brand identity can become correctly recognized by the consumers, and consumers can have various and differentiated experiences. As research method, theoretical concept review and case study on brand communication and VMD were used. Specifically, for review on brand communication, concept, strategies, and space types were explored, and, for review on VMD, concept, purpose, and expressive elements were researched. Also, the study looked at the relevance between and importance of strategy types of brand communication and VMD. Through these reviews, strategy types of brand communication and analysis criteria for VMD application were written based on the research and analysis of 8 cases in Korean and elsewhere. The results of this study is as follows: Based on marketing-oriented thinking with understanding of VMD, the plan must accurately understand the image and identity pursued by the brand, take into account the store layout, atmosphere, product concept, trend, and display, so that the store can communicate with the customers with cognitive consistency, diversity of senses, and differentiation from other companies. Currently, fashion flagship stores in Korea are concentrated on sales in expressing VMD, and, therefore, are difficult to deliver brand identity to consumers and they require diversity in expressive elements in doing so. Therefore, in the interior space design of fashion flagship stores in Korea, brand communication must enhance cognitive, behavioral, relationship, and culture marketing, and, requires confirming VMD expression in details by linking with brand communication and specific expressions based on it.

The convergence of artificial intelligence with smart factories or smart mechanical systems has been actively studied to maximize the efficiency and safety. Despite the high improvement of artificial neural networks, their application in the manufacturing industry has been difficult due to limitations in obtaining meaningful data from factories or mechanical systems. Accordingly, there have been active studies on manufacturing components with sensor integration allowing them to generate important data from themselves. Additive manufacturing enables the fabrication of a net shaped product with various materials including plastic, metal, or ceramic parts. With the principle of layer-by-layer adhesion of material, there has been active research to utilize this multi-step manufacturing process, such as changing the material at a certain step of adhesion or adding sensor components in the middle of the additive manufacturing process. Particularly for smart parts manufacturing, researchers have attempted to embed sensors or integrated circuit boards within a three-dimensional component during the additive manufacturing process. While most of the sensor embedding additive manufacturing was based on polymer material, there have also been studies on sensor integration within metal or ceramic materials. This study reviews the additive manufacturing technology for sensor integration into plastic, ceramic, and metal materials.

In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP) in aerospace, renewable energy and other industries, due to its low weight and relatively good mechanical properties compared with traditional metals. However, due to the high cost of petroleum-based precursors and their associated processing costs, CF remains a specialty product and as such has been limited to use in high-end aerospace, sporting goods, automotive, and specialist industrial applications. The high cost of CF is a problem in various applications and the use of CFRP has been impeded by the high cost of CF in various applications. This paper presents an overview of research related to the fabrication of low cost CF using polyethylene (PE) control technology, and identifies areas requiring additional research and development. It critically reviews the results of cross-linked PE control technology studies, and the development of promising control technologies, including acid, peroxide, radiation and silane cross-linking methods.
