수자원 수급계획은 보통 물수지분석에서 파악된 수자원의 양에 따라 수립한다. 그러나 그것은 상품의 이동과 같은 국제교역을 고려하지 않은 폐쇄적인 수급계획이다. 물수지분석에 가상수 개념을 도입하면 상품의 수출량과 수입량을 고려한 수자원 수급계획을 수립할 수 있다. 기존에 활용하는 직접적인 물 사용(지역 내에서 가용한 각종 수자원)과 가상수를 고려한 간접적인 물 사용(지역 외에서 수입한 상품생산에 소요된 타 지역의 수자원)을 종합적으로 고려하기 때문이다. 그러나 한국에서는 아직 가상수의 개념이 국가 수자원계획 수립에 본격적으로 반영되고 않고 있다. 국내외에서 발표된 가상수 산정연구 논문에서는 가상수 산정과정이 생략되거나 일부만 제시된 사례가 많다. 따라서 가상수의 산정과정 및 거래량의 적절성을 파악하여 실무에 활용하는데 큰 어려움이 존재하고 있다. 본 연구는 한국에서 수출입하는 가상수량 산정을 위한 물발자국 적용값을 구체적으로 제시하고자 한다. 농축산물의 국제 이동량, 물발자국 적용값, 가상수 거래량을 파악하는 과정을 기술하고, 이를 기존연구와 비교하고자 한다. 따라서 본 연구에서 제시한 산정과정과 산정기준은 물발자국 및 가상수 연구를 수행하는 연구자들에게 유용한 기초자료를 제공할 것이다.

Korea's original traditional costume designs have a great potential to be re-imagined from a global perspective and developed into high-value-added fashion culture products that can enter the international market. This study applied the structural features of traditional clothing to the design of fashion cultural products. This study developed designs using Beja, Sagyusam, Aekjuem-po, Danlyeong, Cheolrik, Jang-jegori of Korea. To the best of our knowledge, this study is the first to conduct a literature survey of traditional Korean clothing. We designed shirts using Adobe Illustrator and created a pattern with the Yuka program. This design was applied to a three dimensional virtual dressing system called CLO. A survey of individual interest in developed fashion cultural products was also conducted. The shirt designs were obtained by applying the details and structural characteristics of traditional Korean clothing. Among the six shirt designs, when asked which design would be suitable for wearing, gifting, or uniform, the shirts with the design of Danlyeong, Beja, and Sagyusam were generally highly preferred. This study can be used as basic data for the global market for fashion cultural products, and can contribute to the inheritance and development of culture and tradition by maintaining Korea's uniqueness in the modern global era and increasing tourism revenue.

Virtual idols have aroused wide attention as a novel product of the idol industry in the digital era over the past few years. The population of China determines that virtual idols have a huge fan market. As a digital cultural product closely connected with fans, virtual idols are im-portant to gain insights into the correlation between fan satisfaction and virtual idol functions. In accordance with the KANO demand model, this study first classifies and explains the specific functions of virtual idols into four quadrants, including attractive, must-be, 1D (One-Dimensional), and indifferent. Subsequently, the satisfaction of fans of virtual idols with specific functions in each quadrant are analyzed using a questionnaire. This study suggests that virtual idols have one at-tractive quality, three 1D quality, two must-be quality, and five indifferent quality functional elements. This study qualitatively analyzes the functional elements of virtual idols through fan satisfaction based on the KANO model, which provides valuable help for future research in the field of virtual idols and producers in this field.

Digital technology introduced into the clothing and fashion industry is evolving to digital virtual fashions and consumer-centered mass-customized production systems. Today the application of such 3D virtual try-on systems is being expanded gradually in the clothing industry. This study purposed to make virtual avatars and virtual garments using OptiTex and V-stitcher virtual software and compared the appearance of the virtual garments put on the virtual avatars. For this, we created virtual avatars and virtual garments using body measurements obtained from jive subjects of top jive body shapes, respectively, using $[TC]^2$ body scanner. According to the results of comparing the outcomes of the two different virtual software systems, virtual avatar II of V-Stitcher tended to have a more round and lifted hip and the waist line at a higher position. In addition, the body curves and shapes of a virtual avatar affect the appearance of virtual garments. This study applied the same body measurements to virtual avatars and the same pattern to virtual garments, but when different kinds of virtual software were used, the virtual avatars and virtual garments showed different appearance and fit. This result may mean that when customers buy apparel products using different kinds of virtual try-on systems, their evaluation of appearance can vary depending on the virtual try-on system. Therefore, research needs to be made actively for the development and use of linkage programs that can reflect actual body measurements between virtual software systems and 3D body scanning systems.

The rapid development of information technology has much influence on architectural design. Collaboration beyond time and space has been possible by networking the work environment and digital products. Thus, the virtual design studio on architectural design is getting more important than ever before. This research investigates a virtual design studio methodology for effective collaboration. The building design process and the communication model are studied and possible modes of design collaboration are defined. This paper proposes an internet-based Virtual Reality(VR) communication tool as well as new design methodology that we call the 'Hybrid Design Methodology'. We expect that this design methodology will dramatically increase design feedbacks, and thus results in better design alternatives. There are two issues involved in developing the collaborative virtual design studio: 1) an intuitive interface that presents collaborative relations, and 2) three-dimensional computer-mediated communication tool using sketch as a modeling method. Further research issues identified at the end of the research include developing algorithms that translate mapping images to polygons for the drafting phase in the design process.

The primary goal of virtual prototyping is to eliminate the need for fabricating physical prototypes, and to reduce cost and time for developing new products. A virtual prototyping seeks to create a virtual environment where the development of a new model can be flexible as well as rapid, and experiments can be carried out effectively concerning kinematics, dynamics, and control aspects of the model. This paper addresses the virtual environment used for virtual prototyping of a passenger vehicle. It has been developed using the dVISE environment that provides such useful features as actions, events, sounds, and light features. A vehicle model including features, and behaviors is constructed by employing an object-oriented paradigm and contains detailed information about a real-size vehicle. The human model is also implemented not only for visual and reach evaluations of the developed vehicle model, but also for behavioral visualization during a crash test. For the real time driving simulation, a neural network model is incorporated into the virtual environment. The cases of passing bumps with a vehicle are discussed in order to demonstrate the applicability of a set of developed models.
