The properties of 18 K red gold solder alloys were investigated by changing the content of In up to 10.0 wt% in order to replace the hazardous Cd element. Cupellation and energy dispersive X-ray spectroscopy (EDS) were used to check the composition of each alloy, and FE-SEM and UV-VIS-NIR-Colormeter were employed for microstructure and color characterization. The melting temperature, hardness, and wetting angle of the samples were determined by TGA-DTA, the Vickers hardness tester, and the Wetting angle tester. The cupellation result confirmed that all the samples had 18K above 75.0wt%-Au. EDS results showed that Cu and In elements were alloyed with the intended composition without segregation. The microstructure results showed that the amount of In increased, and the grain size became smaller. The color analysis revealed that the proposed solders up to 10.0 wt% In showed a color similar to the reference 18 K substrate like the 10.0 wt% Cd solder with a color difference of less than 7.50. TGA-DTA results confirmed that when more than 5.0 wt% of In was added, the melting temperature decreased enough for the soldering process. The Vickers hardness result revealed that more than 5.0 wt% In solder alloys had greater hardness than 10.0 wt% Cd solder, which suggested that it was more favorable in making a wire type solder. Moreover, all the In solders showed a lower wetting angle than the 10.0 wt% Cd solder. Our results suggested that the In alloyed 18 K red gold solders might replace the conventional 10.0 wt% Cd solder with appropriate properties for red gold jewelry soldering.

This study was started to study the artistic aesthetic value of the antique artwork which is gradually declining in the field of metal crafts. The aesthetic interpretation of the lines and faces that have been identified through previous researches has been defined as a vitality and repetitive beauty. The researchers here have tried to express the formative works which can be repeated and change. As a result, it was found that the object of inquiry which can express the aesthetic beauty felt in the simple change of the line and the face is possible without the advanced technique of the difficult technique or the molding method through the natural and gradual change of the line and the face rather than the regular repetition. Through this study, it was found that the use of future lines and surfaces could be utilized as a variety of aesthetic expression methods as molding elements.

In the past, commercial advertisements were produced mainly by advertisements that introduced functions, descriptions, or brands that the product had. However, the current advertising market appeals to the product by projecting emotion into the product in line with the consumer's expanded role of storytelling. Nudge effects can help you make the right choice in an economic and behavioral sense. Storytelling, which includes these nudge effects, allows people to communicate with people, thereby allowing consumers and businesses to move in the direction they want. This study understands the concept of nudge effect through commercial advertisement of Seoul Milk and studies the impact of corporate commercial advertisement on the analysis of the interactions between nudge effect and storytelling on the company's perception change as a consumer. The purpose of this study is to study the influence of the nudge effect. The results of this study have affected the perception of the entity, affected by the ripple effect of the nudge effects.

The Fourth Industrial Revolution has emerged, and technologies of various industries are being converged, compounded, or clouded computing, mobile, or big data. The emergence of a variety of skills and new jobs to match them is bringing the public out of the education and occupation of traditional metal crafts. In this change, craft education should find and study the education method suitable for the present times, and apply it to the educational field to raise public interest and revival. To this end, we will investigate the cases of education in other industries where new materials or technologies have been introduced, and use them in education of traditional metal craft techniques. In addition, we will investigate various cases and features of 3D printing technology and use it for education in craft techniques that have limited time, space and resources.

The purpose of this study is to understand the medieval culture and medieval religious costume by analysing and grasping the formative characteristics of image of medieval religious costume in the modern fashion that were represented to the modern fashion, and also to offer materials to predict the history of fashion in the future by considering the progress of modern fashion and recognizing the fashion to be progress. To examine the image of medieval religious costume in the modern fashion, this thesis divided it into avant-garde image, symbolic image, and mysterious image. These can be summarized as follows. First, in avant-garde image, the harmony between characteristic eroticism and heterogeneous materials are expressed and the formative change of religious costume into general costume are expressed. Second, in symbolic image, the symbolic meanings of the medieval clergy man's costume is expressed in modem fashion while its religious meanings and senses are expressed with symbolic image. Third, in mysterious image, the abundant and profound lights and colors express the mysterious senses of the costume and sanctity applied with mosaic painting and stained glass techniques, utilizing the splendor jewelry, spangle and materials, and most of its image reflects exotic and embellish tendency. As a result, this thesis could be described as follows; Previous religious costume of clergy man was used as a mediator between general devotee and God in ceremony, and it was worn by the general devotee to express devotion. This religious costume was utilized in modem fashion, and it gave the avant-garde image and symbolic image of religion. In addition to it, mysterious image was expressed with exotic and embellish tendency.

Casting process includes wax pattern, investment, dewaxing, curing, casting, etc., and each single process is important to achieve a good result. Since 2000, 3D printers have been developed and widely used; as more prefer UV Curavle resin method over wax method, resultant casting defects have become worse. To resolve such problem, preceding research revealed casting defects of existing wax method. In particular, defects of UV Curavle resin method showed difference in investment, dewaxing, deresinating and curing compared to the existing one. Accordingly, results were presented through casting tests; especially, a temperature rising curve only for UV Curavle resin was shown rather than one for the existing method. Lastly, this research classified those not available with direct casting and suggested mold manufacturing. This research is expected to be useful for 3D printer users or those who would conduct direct casting with UV Curavle resin.

This study, which was begun in order to create a metal molding by using lines, a basic element of design, examined various characteristics and concept of line and the beauty of lines based on previous research on the subject. The result showed that formative interpretation of lines largely depends on intentional expression by using thickness and rhythm of lines. In order to obtain a metal molding that provides both visual freedom and beauty, rather than the conventional formative expression of lines, I used red copper plate and Phosphor bronze line for creating a pattern based on transformation and repetition of lines and an artwork based on the pattern. The result was not only a creation of a plane but the senses of three-dimension, speed, and unity in the overall shape. Further research will need to be conducted regarding formative interpretation of lines and emotional and intrinsic beauty through expression of lines.

The Gaya Period is the period in which the nations of Gaya had existed in the Gimhae area. The term 'The Period of the Three Nations', which is widely used, is inappropriate because in ancient Korea, Gaya also existed besides Goguryeo, Baekje and Silla. This term should be corrected for the accurate reconstruction of the history of ancient Korea. Of course, the term 'The Gaya Period' cannot replace 'The Period of the Three Nations'. It just means the period in which the nations of Gaya existed. The Gaya Period refers to the period of about 600 years from about the first century, in which several nations of Gaya began to appear in the Gyeongsangnamdo area, through the falls of Daegarak of Kimhae in 532 A.D. and Daegaya of Goryeong in 562. When doing this, there should be no distortion of the original form of the relics. With the application of traditional techniques and excellent relics, it is believed that it helps to create the high added values by putting culture and tourism together with the development of various designs of cultural goods.
