ABSTRACT
Background White color jewelrys can be said to have been booming since a large number of diamond mines were discovered in the early 1900s. However, while demand for platinum increases over time, the production of platinum decreases, causing disruptions in supply. White gold, which is similar to platinum, is developed and distributed for commercial purposes when such a platinum substitute is desperately needed. Early white gold was not uniform in the type and content of elemental metals used as alloys, Gradually, the production method of standardized white gold will be created. According to the production method, it can be divided into nickel-based white gold and palladium-based white gold. However, nickel and palladium are not commonly used in modern white gold. Nickel causes contact allergens to cause harmful effects on the body, and palladium has soaring prices that have similar economic value to gold and cannot offer economic prices in a highly competitive modern market. Nevertheless, some luxury brand jewelery companies use palladium or platinum as alloy alloys in white gold jewelry. White gold produced in this way will have a clear white color without worry of discoloration. The white color is steadily maintained even without white plating, which means that luxury brands have kept their values.
Methods In the past, the palladium-based white gold alloy ratio was 4: 4: 2, which was made of 40% of gold, 40% of palladium, and 20% of other metals such as silver and platinum. Based on this method, white gold without plating was developed. And alloy alloy considering economic value was intended. Alloys made of 40% gold range from 9 to 10K, but this study attempted to study the white color of one of the most popular and jeweled 18K content. Since 18K is 75% gold, the remaining 25% alloy is the main experimental study on white color improvement. Several metal elements that induce white color are selected and alloyed with alloys up to 25%, the maximum ratio, to compare white color improvement. Among them, the subjects whose color improvements were made were studied whether or not there was any abnormality in the processing of the actual jewelry, the discoloration occurred over time, and whether the white luster was maintained even after the polishing operation. In addition, when expensive alloy material is used, it is produced by gradually reducing the alloy content in consideration of economical efficiency. By comparing and analyzing the created objects, the golden ratio that can achieve the maximum effect with the minimum value is presented.
Result Such research has disadvantages such as the high cost of alloys due to expensive alloys and the resulting increase in product prices, but color improvement can improve the quality of jewelry products and reduce unnecessary plating expenses. The retailer will be able to increase the stability of the display of precious metal products and will be able to construct a new color lineup of low priced existing white gold and expensive white gold. First of all, the seller's excuses due to the discoloration of white gold are unnecessary. It can improve sales performance and resolve dissatisfaction with consumers due to no discoloration. Consumers will also buy more jewelry.
Conclusion The beneficial effects of these studies are expected to be of great benefit to the jewelry market economy. It is expected to play an economic virtuous circle in all jewelry sectors, including the jewelry manufacturing industry and the wholesale and retail distribution industry.

ABSTRACT
Background This study is conducted to identify differences in appearance and motion functionality depending on the sleeve design type, in order to use it as a basis for the development of functional sleeve patterns in active casual clothes.
Methods After controlling all factors other than the sleeve shape, the appearance evaluation, the motion suitability, range of motion and clothing length change measurement according to movement were conducted for 10 subjects of average body type.
Result Appearance evaluation results showed that the Raglan sleeve and the Set-in sleeve were better than the Kimono sleeve in the overall sleeve shape, hanging shape, shoulder line, and front armhole line area(***p<.001). In most areas excluding the sleeves and sleeve lengths, the Kimono sleeve had more overall ease than the Raglan sleeve and the Set-in sleeve(*p<.05). As a result of the motion suitability evaluation, the Kimono sleeve was better than the Raglan sleeve and the Set-in sleeve from the vertical motion 45°(*p<.05), but the motion suitability of the Kimono sleeve also decreased in the vertical motion above 135°. As a result of measuring the range of motion, the range of 125.4°to 141.6°was obtained, but there was no significant difference in sleeve shape. The change in the length of the Kimono sleeve was the greatest at the motion 135°and above.
Conclusion This study showed that the motion functionality of clothing is influenced by several pattern components such as ease, sleeve hanging angle and inner sleeve length, not the design shape of sleeves such as a Set-in sleeve, a Raglan sl eeve and a Kimono sleeve. Therefore, it is important to desi gn a sleeve of an appropriate shape with aesthetic appearan ce and motion functionality according to the purpose of the garment.

ABSTRACT
Background In opposition to the increased rate of purchasing rice online, the dissatisfaction of rice consumers has been increased year by year, but existing studies have failed to provide consumer-centered solutions because they were conducted from the perspective of producers and local governments.
Methods This study seeks to apply the service design methodology to identify key factors that affect the satisfaction of rice purchasing experience from a consumer's perspective. To this end, literature surveys and customer interviews have been used to derive problems and solutions that consumers experience. After producing the prototype, the usability evaluation was conducted.
Result Involvement of the brand is low when customers buy rice, however, the freshness of rice is the most crucial factor for customer’s satisfaction. Therefore, this study proposes a region-based rice sales platform - with the offline store, online App/Kiosk - to reduce price and time of carrying, as solving other in-satisfactions regarding quality, saving, checking information, and delivery of rice.
Conclusion A region-based rice sales platform has been designed to meet key factors in consumer purchasing decisions. It is meaningful that this study has increased consumer satisfaction by applying service design methodology, based on the consumer's perspective, to propose a new consumer-oriented rice purchase platform.

ABSTRACT
Background Disney's animated live-action film "Aladdin" became an issue with colorful costumes as Princess Jasmine's role in the play was emphasized, even though the main character was Aladdin, the male character. In this study, from a feminist perspective, we looked at the women's images in Aladdin films through film costumes, and suggested the direction of visual expression of women's images in real-life movies.
Methods This work combines theoretical and case analysis studies. First, for theoretical research, we redefine terms based on professional books and prior research related to film costumes from a feminist perspective and examine the characteristics of film costumes from a feminist perspective. In addition, a total of nine sets were analyzed for the Jasmine Princess Film Awards of Aladdin, an animated real-life film, and the characteristics were derived by analyzing them according to the flow of the story.
Result The results of this study are as follows: First, perspectives based on the concept and characteristics of feminism theory have been shown to be appropriate as a methodology for character character characteristics and film costume analysis of the film Aladdin's Jasmine. Second, in the live-action film Aladdin, Jasmine's film costumes reflected the characteristics of the story and character in the play. Third, in Aladdin, Princess Jasmine's costume was derived from the characteristics of liberal feminism, radical feminism, and postmodern feminism in terms of feminism.
Conclusion Liberal feminism characteristics were expressed in a design that emphasized practicality and functionality that excluded modern pants and decorations in film costumes, along with Jasmine's story development against patriarchy and gender equality. Radical feminism emphasized the process of Jasmine's self-visiting in Aladdin, and proudly expressed her as a woman with exposure and human exaggeration emphasizing femininity. In postmodern feminism, the characters in the drama, which sympathizes with the people beyond the status of a princess and embraces the two sides of the sex, were displayed through costumes.

ABSTRACT
Background Co-working space has also emerged as a new paradigm, requiring a hybrid approach based on the flexibility, creativity, relationship, and convenience characteristics of co-working space.
Methods We would like to propose a spatial planning direction of the co-working space by dividing the hybrid spatial composition shown in the co-working space into spatial, functional, and morphological components and deriving the hybrid representation characteristics of the co-working space.
Result Through consideration and prior research, the characteristics of the co-working space were derived in four ways, and three components of the hybrid space and five hybrid spatial characteristics were derived. By analyzing the hybrid characteristics expressed in the co-working space, we wanted to find out the results of the work space design, which places a high importance on spatial diversification.
Conclusion Co-working space is where spaces of various personalities are fused with each other, and the working environment creates a de-regional space due to the diversification of spaces such as meetings, play, marketing, welfare facilities, and convenience facilities along with work. It breaks down and expands the boundaries of space for creative tasks, controls and controls boundaries to provide space for creative and enterprising tasks.
