Recently, Chemical Vapor Deposition (CVD) synthetic diamonds have been introduced to the jewelry gem market, as CVD technology has been making considerable advances. Unfortunately, CVD diamonds are not distinguishable from natural diamonds when using the conventional gemological characterization method. Therefore, we need to develop a new identification method that is non-destructive, fast, and inexpensive. In our study, we employed optical microscopy and spectroscopy techniques, including Fourier transform infra-red (FT-IR), UV-VIS-NIR, photoluminescence (PL), micro Raman, and cathodoluminescent (CL) spectroscopy, to determine the differences between a natural diamond (0.30 cts) and a CVD diamond (0.43 cts). The identification of a CVD diamond was difficult when using standard gemological techniques, UV-VIS-NIR, or micro-Raman spectroscopy. However, a CVD diamond could be identified using a FT-IR by the Type II peaks. In addition, we identified a CVD diamond conclusively with the uneven UV fluorescent local bands, additional satellite PL peaks, longer phosphorescence life time, and uneven streaks in the CL images. Our results suggest that using FT-IR combined with UV fluorescent images, PL, and CL analysis might be an appropriate method for identifying CVD diamonds.

Purpose: Unemployment in its general form is a result stemming from the decisions of workers to search for a new and better paying job. In this study, the view that unemployed workers were not simply desiring any job, but one that would maximize their expected future outcome, was examined. Research design, data, and methodology: In order for collection of data and analysis, the panel dates of individual applications for job openings on job search websites were utilized to examine search effort and period for individuals. Results: It was found that the number of applications sent by a job seeker declined over their period of job searching, and that job seekers over a long duration of time tend to send relatively more applications per week throughout their entire search period. The latter finding contradicts the implications of the standard labor search effort models. Conclusions: It can be observed that these job search models fail to capture several key elements in search efforts, and that the search time for an offer is not entirely predetermined by the labor market conditions and socio-economic (individual) characteristics of the searcher. It can be shortened as he or she intensifies their job search efforts.

The aim of the present study was to investigate and analyze a tendency of the Philippines furniture which are not well-known in Korean market yet, but have been emerging as an OEM base, through the Manila FAME 2012. The study was conducted by visiting some furniture companies in Philippines for the active understanding regarding the current status of the Philippines furniture, in consideration of the material, functional and structural aspects of the goods which were exhibited on the Manila FAME 2012. The methods of the investigation were to research the related literatures concerned and materials had been collected over the internet, to visit the Manila FAME 2012 at work and finally to visit furniture companies in Philippines. Manila FAME has been based on the DTI (DTI: Department of Trade and Industry) through CITEM (CITEM: The Center for International Trade Mission and Expositions) since 1983. The exhibition whichincludes various sorts from furniture, traditional artifacts, leisure goods, gifts, jewelry and clothes is becoming such a potent force by integrating three exhibitions such as Manila Now, CEBUNEXT and Bijoux Cebu, what all had been held before the world economic downturn. The features of the Philippines furniture shown on the Manila FAME are as follows: First, they are focusing on the maximum of function to the exclusion of the decoration and they were mostly made of various kinds of mahogany like jambilina, acacia, bamboo, wisteria and Manila hemp growing up in the Philippines indeed and finally there were a lot of the simple designs of the curved line which were exactly the material nature of the wisteria and Manila hemp.

As the international competitive landscape deepens, the need to understand foreign cultures and establish effective strategies is increasing. At the beginning of the 20th century, Cartier actively developed exotic designs to secure international competitiveness; theses designs have also been used as design prototypes for Cartier in modern times. The purpose of this study is to analyze the color characteristics and types of exotic designs in the early 20th century, which was a turning point in Cartier's design. After studying the literature, a total of 248 exotic designs were presented in Cartier catalogs. This study also selected overseas monographs from the early 20th century, and their design types were classified and color analysis was performed based on the Natural Color System(NCS). Cartier's exotic designs cover wide range of styles, such as Chinese, Japanese, Persian, Indian and Egyptian styles. Multicolor, primary colors, and contrast are all strongly expressed. 97% of designs contained multiple colors, with at least two colors and maximum of six colors. The most frequently used colors are red, green, and blue, which means that only 9% of the designs do not contain the three colors, showing a high preference for theses three colors. In addition, color combinations of red and green, red and blue, or all three colors are used to show high contrast and utilize complementary colors, or near complementary colors, for coloration. This study is meaningful in that it analyzes the color characteristics of Cartier's exotic designs and translates them into practical data for establishing the color strategies of companies in the global market.

과거 상업광고는 제품이 가지고 있는 기능, 설명, 또는 브랜드를 소개하는 식의 위주로 광고로 제작되었다. 그러나 지금의 광고시장은 스토리텔링 역할이 확대된 소비자의 감성에 맞추어 제품에 감성을 투영시켜 상품을 어필하고 있다. 넛지효과는 경제 행동학적 의미로 올바른 선택에 도움을 줄 수 있다. 이러한 넛지효과가 포함되어있는 스토리텔링에는 사람과 사람들을 소통하게 하고, 그로 인해 소비자와 기업을 소통하게 해주며, 기업이 원하는 방향으로 유도하게 한다. 본 연구는 서울우유의 상업광고를 통하여 넛지효과의 개념을 이해하고 광고 속의 넛지효과와 스토리텔링 사이 상호작용의 분석에 대한 기업의 상업광고가 소비자로 하여 기업의 인식변화에 준 영향을 연구한다. 본 연구는 넛지효과가 가진 영향력에 대한 연구를 목적으로 한다. 본 연구의 결론은 소비자는 넛지효과의 파급력에 영향을 받아 기업의 인식에 어떤 영향을 주었는지에 관한 결과를 보여준다.

산업혁명 이후 기계로 만든 공산품이 시장의 대부분을 차지하고 있지만, 최근에는 장인의 노력, 품질에 대한 믿음, 제품의 희소성, 제품을 사용함으로써 얻는 자부심 등을 이유로 많은 소비자들이 같은 범주의 공산품보다 더 비싼 가격을 주고 핸드메이드 제품을 구매하고 있다. Etsy.com은 세계 최대 온라인 핸드메이드 플랫폼으로 2015년 4월 기업공개에서 2조원이 넘는 자금을 조달하면서 온라인 핸드메이드 플랫폼의 잠재력을 증명하였다. 그러나 실제 온라인 플랫폼 환경에서 이루어진 지능형 서비스 관련 선행연구들을 살펴보면 대부분 공산품만을 대상으로 하고 있어, 핸드메이드 제품에 대한 학술적 접근이 충분히 이뤄지지 않고 있음을 알 수 있다. 이에, 본 연구에서는 신호 이론과 온라인 플랫폼에서의 구매자-판매자 관계 특성에 대한 선행연구를 바탕으로 온라인 핸드메이드 플랫폼에 적용 가능한 핵심 특성요인인 입점 상점 특성(명성, 규모)과 입점 상점 관계특성(정보공유, 관계기간)을 도출한 후, Etsy.com 웹사이트에서 웹 하베스팅 방법으로 수집된 데이터를 이용하여 실증 분석하였다. 분석 결과, 입점 상점 특성 가운데 명성과 규모, 그리고 입점 상점 관계특성 가운데 정보공유는 입점 상점의 총 판매량에 유의한 영향을 주는 것으로 확인되었다. 또한, 입점 상점 특성 중 명성, 그리고 입점 상점 관계특성 중 관계기간은 입점 상점의 가격 프리미엄에 유의한 영향을 주는 것으로 나타났다. 본 연구의 결과로 온라인 핸드메이드 플랫폼에서 지능형 서비스 도입 및 운영을 위한 효과적인 관리 기준을 제시하고, 나아가 입점 상점이 핸드메이드 제품에 대한 판매량 증진 및 가격 프리미엄 극대화를 위한 실질적 전략 마련에 도움이 될 수 있기를 기대한다.
