Game technologies are now applied in various engineering areas such as the simulation of surgical operation or the implementation of a cyber model house. One of the essential and important technology in these applications is cutting of the 3D polygon model in real time. Real-time cutting technology is an essential technology needed to implement the simulation of a building demolition or a car assembly for training or educational purpose. Previous cutting method using the conventional BSP-Tree structure has some limitations in that they divide the whole world including the 3D model and its environment, only into two parts with respect to an infinite plane. In this paper, we show a technique cutting the 3D model in a finite extent in order to solve this problem. Specifically, we restricted the cut surface in a finite rectangular area and constructed the mesh for the divided surface. To show the usefulness of our partial cutting technique, an example of the dismantling process simulation of a nuclear reactor polygon model was illustrated.

It is important to analyze and offer specialized start-ups effect factors for collegians in order to systematically and successfully support technology-centered start-ups of collegians, whose social experience is insufficient. However, consistently changing start ups environmental analysis is difficult, which can be a problem, because technology-centered start-ups factor analysis is carried out depending on statistical package. This paper proposes an ATSA system that demonstrates effect factors on technology-centered start-ups decision making as a hierarchial structure by using AHP, inputs the effect factors to judgment matrix after pre-processing, calculates standardized values and weights, verifies consistency, and draws priorities through weights integration. It was confirmed that the ATSA system can efficiently support decision making for technology-centered start-ups by quantitatively analyzing qualitative factors through experiments by applying multi-criteria decision making to the analyses of start-ups founders' internal and external factors and various start-ups environments.

As a result of growth of digital music market in Korea, Creator's rights and interests have been at the heart of the debate in terms of legal system. In the music industry, digital music revenue has now overtaken records sales and compared to download service it is now clear that music streaming and subscription is mainstream model in the rise of the worldwide market of digital music. This trend is also indentical to the domestic and withholding regulations for music service and creator's rights and interests have become an ever growing issue. Ministry of Culture, Sports ad Tourism decided the revision of withholding regulations for the digital music service in 2013. The amendment is to change its policy of charging music service from the flat rate pricing to a usage-based system. This paper brought forward some disputable points such as fair division of profit, reasonable pricing for consumers etc. about the revision. Therefore, improvement of system and change in the perception of such copyrights are still required for both the encouragement of creator's activities and the high consumer satisfaction.

People observe lots of events around the environment and we can easily recognize the nature of an event from the resulting optic flow. The questions are how do people recognize events and what is the information in the optic flow that enables observers to recognize events. Motor theorists claim that human observers exhibit special sensitivity when perceiving events like speech or biological motion, because we both produce and perceive those events. However, direct perception theorists suggested that speech or biological motion is not special from the perception of all other kinds of event. The purpose of this review article is to address this controversy to critique the motor theory and to describe a direct realist approach to event perception. It is important to understand the fundamental information of how human perceive event perception for the convergence on robotics.

DOI : 10.14400/JDC.2015.13.4.417
Oil-in-water(o/w) nanoemulsions were prepared in the system of water/Span 80-Tween 80/long-chain paraffin oil via PIC method. With the increase of preparation temperature from 30 oC to 80 oC, the diameter of emulsion droplets decreased from 150 nm to 40 nm. By varying the HLB of mixed surfactants, we found that there was an optimum HLB around 13.0~14.0 corresponding to the minimum droplet size. The size of emulsion droplets increased upon increasing the ratio of oil/emulsifying agent. At
, the size of nanoemulsions could be kept constant more than 2 months. The increase in preparation temperature makes it possible for producing monodisperse nanoemulsions. Once the nanoemulsion is produced, the stability against Ostwald ripening is outstanding due to the extremely low solubility of the liquid paraffin oil in the continuous phase.
