본 논문에서는 PAR-트리라는 공간색인구조를 제안한다. PAR-트리는 object distribution heuristic(객체분할법)으로 absolute crowd index(절대 복잡도)를 사용하여 공간 데이터 객체를 여러 개의 데이터 공간에 균일하게 배치함으로써 질의처리 속도를 향상시킨다. PAR-트리는 MXR-트리에 비해 높은 공간활용도와 빠른 질의 반응시간을 보임으로써 다차원 데이터베이스를 위한 효율적인 색인구조로 사용이 될 것으로 기대된다.

Due to the recursive updating nature of background model, previous background modeling methods are often perturbed by crowd scenes where foreground pixels occurs more frequently than background pixels. To resolve this problem, an adaptive background modeling method, which is based on the well-known Gaussian mixture background model, is proposed. In the proposed method, the learning rate of background model is adaptively adjusted with respect to the crowdedness of the scene. Consequently, the learning process is suppressed in crowded scene to maintain proper background model. Experiments on real dataset revealed that the proposed method could perform background subtraction effectively even in crowd situation while the performance is almost the same to the previous method in normal scenes. Also, the F-measure was increased by 5-10% compared to the previous background modeling methods in the video of crowded situations.

The level-of-detail (LoD), which is a method of reducing polygons on mesh, is one of the most fundamental techniques in real-time rendering. In this paper, we propose a novel level-of-detail technique applied to the virtual character's motion (Motion LoD). The movement of a virtual character can be defined as the transformation of each joint and it's relation to the mesh. The basic idea of the proposed 'Motion LoD' method is to reduce number of joints in an articulated figure and minimize the error between original and simplified motion. For the motion optimization, we propose an error estimation method and a linear system reconstructed from this error estimation for a fast optimization. The proposed motion simplification method is effectively useful for motion editing and real-time crowd animation.

Platform finance is emerging as an alternative finance for SMEs by suggesting a new funding source based on a new technology named FinTech. The essence of this business is the adapting ICT challenges to the financial industry that can adequately reflect risk assessment using Big Data and effectively meet individual risk-return preference. Thus, this is evolving as an alternative to existing finance in the form of P2P loans for Micro Enterprises and supply-chain finance for SMEs that need more working capital. Platform finance in Korea, however, is still at an infant stage and requires policy support. This can be summarized as follows: "Participation of institutional investors and the public sector," meaning that public investors provide seed money for the private investors to crowd in for platform finance. "Negative system in financial regulations," with current regulations to be deferred for new projects, such as Sandbox in the UK. In addition, "Environment for generous use of data," allowing discretionary data sharing for new products," and "Spreading alternative investments," fostering platform finance products as alternative investments in the low interest-rate era.

Crowd funding can be understood that consumers are participated in production process before real commercialization. These days there are some expectancy and worry about foreign capital influence to Korea Wave. This study is to find out the possibility that Korea Wave can lead to investment to make new cultural contents and find possibility as new investment funding source. Expecially this research did survey at Gwangjou in China with 20s and find their possibility to invest money for crowd funding related to Korea Wave and we evaluate consumer's Korea Wave preference. The results showed that with more preference of Korea Wave decrease consumer's perceived risk and increase consumer's perceived benefit. With this research we can find some possibility of motive for consumer's direct investment to Korea Wave project in Korea.

Crowd Sourcing-based Social App Manufacturing environment, a small app development project by a team of anonymous virtual performed without the constraints of time and space, and manage it for the app development process need to be automated method. Virtual teams with anonymity is a feature of the Social App Manufacturing, is an important factor that increases the uncertainty of whether the completion of the project or reduction in visibility of the progress of the project. In this study, as one of how to manage the project of Social App Manufacturing environment, the impact of risk that can be used to quantitatively measure the impact of the risk of delay in development has on the project also proposes a measurement model. Effects of risk and type of the impact of risks associated with delays in the work schedule also define the characteristic function, measurement model that has been proposed, suggest the degree of influence measurement equation of risk of the project in accordance with the progressive. The advantage of this model, the project manager is able to ensure the visibility of the progress of the project. In addition, identify the project risk of work delays, and to take precautions.

In order to find methods to encourage active private participation for efficient road maintenance, this study examined the status of the road improvement project and the development of the private capital utilization improvement project. Based on this, the study conducted a case study and a financial feasibility study that applied the new business method and selected the applicable business method. As a result, it is analyzed that the method of using Crowd Funding is more advantageous than the private scheme of the private capital utilization improvement project. This is because it will be highly effective in raising funds from users of highway users, especially users of improvement projects. In addition, it can also mean that the road users who suffer from inconvenience due to the construction can return the toll profit of road construction to the user.
