This study analyzes traditional women's Hu costumes of the Tang dynasty, and deploys a creative fashion design to converge contemporary and traditional styles. In this costume, women wear a robe with striped or plain patterns in the lower part of the pants, and it appears frequently in red and yellow colors. Depending on the sleeve, it is either a round collar or a turn down collar robe. In the Hu hat, the huntuomao and juanyanxumao were leather and mili and weimao were used to prevent the sand from flowing. This study uses the CLO 3D program with the "moment" theme based on the Hu costume for women to deploy 4 pairs of fashion design and to produce works for 2 pairs. The 3D virtual clothing program demonstrates important effects in design deployment and pattern arrangement through its efficiency and convenience of clothing production. The CLO 3D program was closely combined with the 2D design and the 3D affect, and it heightened the efficiency in saving the processing time and energy of the sample clothes. Through facilitating the 3D digital fashion design, the production may reduce time needed and contribute to an effective economy, and it may compare digital fashion design to actual products as well as illustrate the potential of digital fashion design.

The purpose of this study is to propose a modern use of traditional culture by developing creative fashion designs that combine modern and traditional styles based on an analysis of traditional costumes of women in the Tang Dynasty of China. The characteristics of the Tang Dynasty women's costume are as follows. The Tang Dynasty women's costume consists of a short coat (衫, Shan), skirt (裙, Qun), half-arm shawl (半臂, Banbi), and short embroidered cape (帔, Pei). The colors are succinct and elegant, commonly red, yellow, green and navy blue in its entirety. It may be classified by pattern that blend plant patterns, animal patterns, geometric patterns, and two or more mixed patterns. On the basis of the characteristics for traditional women's costume during the Tang Dynasty, the CLO 3D program is employed to develop digital fashion design for four pairs of 3D digital clothing and the production of two pairs of work product. The results are as follows. First, the development of fashion design reflecting the design characteristics of traditional women's clothing in the Tang Dynasty of China could be expressed as fashion design reflecting unique values while connecting tradition and modernity. Second, the 3D virtual clothing program displays an extremely important effect in design deployment and pattern arrangement by having efficiency and convenience in clothing production. The CLO 3D program is closely combined with the 2D design and 3D effect and heightened efficiency while being appropriate to realize sustainability while saving processing time and energy for the sample products.

오늘날의 지식기반경제에서 핵심적인 역할을 수행하고 있는 가상 커뮤니티의 성공을 위해 턴오버(turnover)는 매우 중요한 의미를 가지고 있다. 그런데, 이에 대한 연구는 많이 부족한 실정이다. 우선, 턴오버를 측정하는 방법부터가 명확하지 않다. 가상 커뮤니티에서 새로운 구성원의 유입은 비교적 확실하게 인지할 수 있지만, 탈퇴는 명시적으로 탈퇴 처리를 하는 사람들이 드물고 재방문 가능성이 상존하기 때문에 구별하기가 쉽지 않다. 그리고, 특정기간 동안 임의의 구성원이 해당 커뮤니티를 위해 활동하고 있는 진정한 구성원인지를 판단하는 방식이 분명하지 않아 전통적인 조직의 턴오버 공식을 그대로 적용하기 힘든 면이 있다. 본 연구에서는 이러한 한계점과 가상 커뮤니티 구성원의 행위 패턴을 고려하여, 일차적으로 턴오버를 포함한 가상 커뮤니티 구성원의 유동성(fluidity) 관련 척도들을 도출하고, 이를 토대로 유동성과 가상 협업 성과의 관계를 작업의 전문적인 특성을 반영하여 분석하였다. 요컨대, 대표적인 지식 협업 커뮤니티인 영어 위키피디아의 2,978개 피쳐드 아티클(featured article)에 대한 지식 협업 행위로부터 다음과 같은 결과를 얻었다. 첫째, 협업 효율성에 대한 턴오버의 관계는 오른쪽 부분이 짧은 U자 형태를 보이며, 똑같은 턴오버율에 대해 보다 학문적인 아티클을 완성하는 것이 더 오래 걸리고, 이 차이는 턴오버율이 증가함에 따라 감소한다. 둘째, 협업효율성에 대한 재방문기간의 관계는 왼쪽 부분이 짧은 U자 형태의 관계를 가지며, 전문적이지 않은 작업일수록 재방문기간의 일단위 변화에 대한 협업 효율성의 변화가 크다. 그리고, 똑같은 재방문기간에 대해 보다 학문적인 아티클을 완성하는 것이 더 오래 걸리며, 이 차이는 재방문기간이 평균이상으로 증가함에 따라 더욱 커진다. 셋째, 협업효율성에 대한 월(month)별 유입 신규 구성원 수의 관계는 왼쪽 부분이 짧은 역 U자 관계를 가지며, 이 관계에 대한 작업 특성의 영향은 유의하지 않은 것으로 보인다.

Recently, cosmetic shops are facing a complicate economy situation and a great number of brands are attempting two-way communication with customers, not one-way communication. 'Brand' equity is important to deliver virtual brand mark as visual image. We have 4 steps for brand identity structure, and this study is about the first 'brand-awareness' and the second step 'brand-image'. We investigated the correlation between brand-awareness and brand-image after searching which spatial elements are highly effective to both steps as we designated 5 cosmetic shops. We already organized the means of spatial analysis and we separated into two elements, constructive and decorative. For constructive element, a shop needs a distinct ceiling and wall design, and for decorative element, strong brand image communication is required through showcase design. We proved that brand awareness and brand image have the correlation, which also can be in direct proportion, by regression analysis. The result of this study shows that improving brand awareness as the primary element for cosmetic road shop can be an effective way to enhance brand image.

Bitcoin and blockchain are often making headlines not only on TV or media but also among the public in today's society. These technologies have been developed after the risk of the centralized financial system came to the fore during the 2007 global financial crisis. Since then, an anonymous inventor called Satoshi Nakamoto penned the bitcoin white paper where a blockchain-based reference implementation was introduced. Bitcoin was able to achieve unprecedented growth by positioning itself as one of the top global currencies in terms of market capitalization after five years since its development. The pace of Vietnam's economic development is notably fast among Asian nations, while the nation was expected to be a Southeast Asian blockchain hub but they have banned virtual currency trading recently. However, they've also designated the State Bank of Vietnam (SBV) as a responsible agency for the research of blockchain-based cryptocurrencies, the construction of a service ecosystem, and their test operations. The fast-growing economy, increasing number of smartphone users, and the Vietnam government's support policies for startups substantiate these efforts. Therefore, this paper attempts to study the current status of Vietnam's blockchain technology that has been considered to be the center of blockchain systems right behind Singapore, and its implications for Korean companies.
