현재 국내 주얼리(gold alloy) 제품을 생산함에 있어 주조 방법은 크게 대기 중 주조(흡입주조) 방법과 진공주조 방법으로 나누어진다. 국내 주얼리 제조업체의 약 90%이상이 대기 중에서 주조하는 흡입주조방법을 통해 제품을 제작하고 있고, 국외의 경우, 대다수 진공주조방법을 통해 제품을 제작하고 있다. 본 연구에서는 주얼리 제품을 생산할 때 사용되는 합금재료(master alloy)가 동일한 조건에서 주조방법을 달리하여 각각 24개씩 총 48개의 14K yellow gold alloy 제품을 제작한 후 열처리를 통해 각각의 기계적, 물리적 특성분석을 비교 분석하였다. EPMA (Electron Probe Micro Analysis)분석을 통해 합금재료 및 제품의 구성성분을 조사하였고, ICP-MS (Inductively Coupled Plasma Mass Spectroscopy)를 사용하여 성분에 대한 정량분석을 실시하였다. 용체화처리(solid solution treatment)는 $700^{\circ}C$, 30분의 조건으로 실시하였고, 시효경화처리(age-hardening)는 $200{\sim}300^{\circ}C$의 온도범위에서 $50^{\circ}C$ 간격으로 실시하였다. 열처리 전과 후 시료의 grain 들의 배열 및 size 변화를 관찰하기 위해 식각 후 OM (optical microscope) 및 SEM (Scanning Electron Microscope)를 통해 분석하였다. 열처리 전 제품의 경도측정결과 대기 중 흡입주조방법 및 진공 주조방법을 통해 제작된 제품이 각각 119 Hv, 126 Hv로 나타났고, 용체화 처리 후 98 Hv, 92 Hv로 감소하였다. 시효경화 처리 후의 경도변화는 대기 중 흡입주조 및 진공주조방법을 통해 제작된 제품 모두 $270^{\circ}C$에서 각각 154 HV, 166 HV로 가장 높은 경도 값을 나타내었고, $270^{\circ}C$ 이상에서는 과시효(over aging)현상으로 인해 경도 값이 다시 감소하는 경향을 나타내었다. EPMA mapping 분석을 통해 주조방법에 따라 각각 제품의 구성성분분포도를 확인하였다. 이를 통해 열처리 전 다소 불균일하게 분포되었던 성분들이 열처리 후 균일해짐을 확인할 수 있었다.

This research is aimed to discuss for Korean cultural contents; symbol structure of Minwha painting which not only expresses openness, flexible expression and methods of communication of our ancestors but also possibly passes down as precious cultural heritage to modern society with new developed mediums. From this perspectives, as a method of research, modern jewelry design is created through digital process with linguistics analysis of its symbol structure that contains universal wishes of people. As a result, this research showed jewelry design and design process, titled "Blossom" and "Big Smile" grafting modern technology of 3D digital tool onto universal meaning symbolized by Peony flower, wealth and honor, and also grafted modern manufacturing methods of 3D printing and laser cut onto openness and flexible thinking in symbol structure in Minwha.

This study is about the class model that can demonstrate the modeling ability using the spatial perception capability on basic modeling required for jewelry design majors and the most important perspective method in jewelry design. The outputs were obtained by presenting the topics for creative activities to students after theoretical explaining how to present a spatial sense and presenting practical classes on basic shapes, stereoscopic shapes and perspective methods. While the existing basic molding classes were only practical classes, this study presented students with a class model that allows them to use creativity, basic perspective, and spatial sense together. And it was found out evaluation method that both students and professors can relate to each other through the intensive education effects and clear evaluation standards. I hope that this paper will continue to study more diverse materials and convergent class models.

This study was conducted on the premise of the development of cultural products using relic assets of traditional culture in a knowledge and information society led by culture and soft power. It was conducted in the context of exploring the possibility of cultural content products of Wa-Dang relics excavated from traditional architecture in the Unified Silla Period and expanding the scalability of commercialization motifs that are highly useful in jewelry design. First, the original form, material, use, size, meaning, and formative aesthetics of Wa-Dang were identified through literature and media research. Among the considered Wa-Dang, 10 types of Wa-Dang which represent the category and have values in modules and patterns were selected, and, then, circular images were extracted and modularized with a "formal simplification technique." Based on the "mathematical symmetry analysis technique," which is a method of systematizing pattern composition arrangement format. we derived a planar formative element that can be used in the development of the cultural content industry and jewelry design. In order to expand its usability in the jewelry industry in the future, it was presented as a 2D digital image. In the future, we hope more studies on the various cultural content industry utilizing the traditional culture will be carried out.

Digital is the main topic of 21C design. Experts analyzed that pop art and related cultural products are becoming popular as digital generations of twenties to forties are centered of new art culture. This survey is to suggest the differentiated jewelry products which are out of the existing products as combining the embodiment of various colors by using celebrities who are taken kindly to and the lenticular which can be image converted through an optical illusion. As public's living standard is getting improved, design elements would come into the spotlight. Therefore, this research is expected to work as the part of an epoch-making design in the jewelry industry by extending the design field.

The purpose of this study is to examine the evolution of precious metal and gem stores, and to derive the characteristics of this period from the government, industry, and consumers. Correspondingly, the contents of daily newspaper articles during this period were analyzed using Naver's news library search engine. The historical development process is as follows. Before the Korean War, precious metal jewelers operated in Jongno, Namdaemun, and Chungmuro, dealing with gold, silver, and platinum. Large stores not only sold jewelry and watches, but also functioned as craftsmen and watch repairers. After the war, a shopping district for precious metals and jewelry was formed around Midopa Department Store. By 1963, the number of jewelry stores in Seoul increased to about 130 and to about 280 by 1966. The characteristics of the government, industry, and consumers are as follows. The government continued to implement a policy to regulate the precious metal and jewelry industry. Despite challenges, the industry exhibited the potential for foreign currency acquisition and growth through domestic amethyst. Consumers could access information regarding precious metal jewelry in daily newspapers. In the late 1960s, various types of jewelry were distributed in line with an increase in income levels.

The number of people living with a pets is increasing. The size of related industries are expanding. There is an increasing demand for various designs, functions, and materials for pet accessories. Therefore, this study proposes the development of a pet jewelry design using a phosphorescent pigment. The phosphorescent pigments have an advantage of emitting light by themselves even in dark places. The final design was derived by manufacturing this as a gemstone cutting-type resin and applying it to the development of jewelry design for pets.

It was developed exporting jewelry products so that export those goods by industrial-educational corporation. I concluded an agreement with Hyun-dai co. Ltd, known as a specialist of the cultural goods producing company. By differentiation of the designs for expressing cultural images of korea, we tried to make competitive goods so that it can give value-added profits to the company. And we tried to settle specialization, securing specialty, outsourcing and utilize the spearheaded instrument Jewel CAD, R/P System. Also we tried to contribute to achieve the aims that cost down, task cooperating, systematization by reporting those things to the jewelry business world.

The purpose of this study was to examine variables which influenced on fashion jewelry consumers' purchasing behavior. 565 respondents living in Seoul and its suburb were surveyed for this study. For data analysis, descriptive statistics, factor analysis, ANOVA, and regression were used for this study. As the result, the frequencies of purchasing toward the fashion jewelry products were associated with materialism, brand royalty, reference group influence. Also, results revealed that materialism and brand royalty accounted for 41% of the explained variance in the frequency of purchasing products on fashion jewelry. Based on these results, fashion jewelry marketing strategies would be suggested.
