With the success of the world's first 3D computer animated film, "Toy Story" in 1995, industrial development of 3D computer animation gained considerable momentum. Consequently, various 3D animations for TV were produced; in addition, high quality 3D computer animation games became common. To save a large amount of 3D animation production time and cost, technological development has been conducted actively, in accordance with the expansion of industrial demand in this field. Further, compared with the traditional approach of producing animations through hand-drawings, the efficiency of producing 3D computer animations is infinitely greater. In this study, an experiment and a comparative analysis of markerless motion capture systems for facial expression animation has been conducted that aims to improve the efficiency of 3D computer animation production. Faceware system, which is a product of Image Metrics, provides sophisticated production tools despite the complexity of motion capture recognition and application process. Faceshift system, which is a product of same-named Faceshift, though relatively less sophisticated, provides applications for rapid real-time motion recognition. It is hoped that the results of the comparative analysis presented in this paper become baseline data for selecting the appropriate motion capture and key frame animation method for the most efficient production of facial expression animation in accordance with production time and cost, and the degree of sophistication and media in use, when creating animation.

The Fourth Industrial Revolution, centered on intelligence and information, began to take hold in 2016. This study uses virtual reality technology, which is the most popular technology of the Fourth Industrial Revolution. The purpose of this study is to explore a Virtual Walk-through method, which can be easily applied to landscape architecture. At present, virtual reality technology is widely used in the fields of games, emergency training, and architectural design. However, in the field of landscape architecture, it is still in the development stage. In addition, most of the traditional ways to display virtual reality use 2D images, but such methods have some limitations. Therefore, this research addresses the three stages of "design-exhibition-experience" and puts forward a new simple method called 'Virtual Walk-through' that breaks from traditional landscape design exhibitions. The results show that compared with traditional methods, virtual reality has many advantages, such as the freedom of experience, a diversity of viewing angles, information supply, interaction, etc. It can show high quality images and effects, which are suitable for landscape design. It provides an evaluation method for garden design that can be utilized in the future. It is simple and has value as it can reflect the method and the expected effects. Virtual reality technology can bring an infinite number of prospects to the development of landscape architecture.

As the importance of Culture Technology (music, publication, mobile, film, video, cartoon, animation, character, game, broadcasting etc) is increased, the field of character industry recently has been recognized as an independent brand value beyond the existing view point of simple designing; it also has been given much attention as a main axis leading the cultural industry of the 21 st century. The character of a local government plays roles such as a symbolic part of a region, parts of tourism and public relations, and a profit-making function, which results into generation of regional image and activation of regional economy. However, the present application strategy of the character is only limited to an early stage of regional advertisements. In this context, this study is aimed to investigate and analyze the character development of local governments, especially 31 cities and goons of Gyeonggi Province, comparing with those of local governments of Japan. In the long run, this will provide some suggestions for strategy of character applications. Then, this research is expected to be used as basic reference materials for character development of other local governments and government agencies.

The voluntary agreement between industries and government on the recycling of wastes has been analysed. The agreement is one of the threatened voluntary agreements. Theoretically these agreements make it possible to fulfill recycling goals with minimized cost. It is the objective of this paper to evaluate the efficiency of the voluntary agreement on recycling wastes by examining of Nash Equilibrium. In the first place, the equilibrium of a bilateral agreement between the representative of industries (association of firms) and government will be analysed to confirm if cost minimization strategies by the association result in a sub-game perfect Nash Equilibrium. This is followed by an analysis of a multilateral agreement among the members of the association to see how the equilibrium and efficiency conditions change. We tried to find some implications that the result of the analysis casts on the environmental policy matters.

Focus level has been important mental state in user study. Cardiac response has been related to focus and less clarified. The study was to determine cardiac parameters for recognizing focus level. The sixty participants were asked to play shooting game designed to control two focus levels. Electrocardiogram was measured during task. The parameters of time domain and frequency domain were determined from ECG. As a result of independent t-test, RRI, SDNN, rMSSD and pNN50 of time domain indicator were statistically significant in recognizing focus level. LF, HF, lnLF and lnHF of frequency domain were observed to be significant indicator. The rule base for recognition has been developed by the combination of RRI, rMSSD and lnHF. The rule base has been verified from another sixty data samples. The recognition accuracy were 95%. This study proposed significant cardiac indicators for recognizing focus level. The results provides objective measurement of focus in user interaction design in the fields of contents industry and service design.
