The purpose of this study is to identify the limits of law on intellectual property generated from dance performance creation. It is based on literature research. It focus the way of dance works protection through current intellectual property laws after 21th century and the limits of them. First, it summarized copyright law, patent, trademark right, and trade secret. Second, it study the choreography of meaning and the process on field of the convergence. At last it summarized the limits of the intellectual property mentioned above. As a result, it is hard to fully protect the right by law whereas performing art create new form of style to communicate with audiences as develop convergence contents. There are significance on this study that summarize the intellectual property law and their limits when they applied to intellectual property from choreography, as a process of dance creation of today.

This study describe a new method to control posture and velocity for a wheeled mobile robot using visual feedback control method with a position based visual feedback. To slove the problem of vibration phenomena which were shown in the previous researches using a simple switching function based on a threshold, the proposed visual servo control law introduces the fusion function based on a blending function. The chattering problem and rapid motion of the mobile robot can be eliminated. And we consider the nonlinearity of the wheeled mobile robot unlike the previous visual servo control laws using linear control methods to improve the performances of the visual servo control law. The proposed posture control law using visual servoing is verified by a theoretical analysis and simulation and experimental results.

Private security guards are not given special legal privileges to the general public, and holds the same legal status. However, the private security industry has been the expansion of business areas, but some legal rights to bring a limited time you can claim that. In this study, major countries such as Japan, the United States and comparative analysis of the legal status of the security guards and private security guards in Korea about the legal status of the current law on the guards private security law Korea by analyzing the legal status of private security guards to the issue of the legal status and thereby derive an alternative proposes a purpose.

The quantum logic was introduced by G. Birkhoff and 1. von Neumann in order to study projections of a Hilbert space for a formulation of quantum mechanics, and Husimi proposed orthomodular law and orthomodular lattices to complement the quantum logic. Abott introduced orthoimplication algebras and its properties to investigate an implication of orthomodular lattice. The commuting relation is an important property on orthomodular lattice which is related with the distributive law and the modular law, etc. In this paper, we define a binary operation on orthoimplication algebra and the greatest lower bound by using this operation and research some properties of this operation. Also we define a homomorphism and characterize the commuting relation of orthoimplication algebra by the homomorphism.

A number of universities around the world provide various undergraduate and graduate programs for digital forensic. In this paper, we propose a cross-layer program suitable for senior students in the IT and law departments to learn multi-disciplinary convergence subjects. We have first analyzed the key ingredients of digital forensic and then the current programs in several universities. After describing the qualifications anticipated for digital forensic specialists, we have critically analyzed the courses currently offered in the IT and law departments. Based on the analysis and discussions, we have proposed an IT+law program and two flexible operation schemes of the program for securing the desired level of convergence education.

A stable neural network control scheme for unknown non-linear systems is developed in this paper. While the control variable is optimised to minimize the performance index, convergence of the index is guaranteed asymptotically stable by a Lyapnov control law. The optimization is achieved using a gradient descent searching algorithm and is consequently slow. A fast convergence algorithm using an adaptive learning rate is employed to speed up the convergence. Application of the stable control to a single input single output (SISO) non-linear system is simulated. The satisfactory control performance is obtained.

In this paper we introduce the concept of asymptotically almost negatively associated random variables in a Hilbert space and obtain the strong law of large numbers for a strictly stationary asymptotically almost negatively associated sequence of H-valued random variables with zero means and finite second moments. As an application we prove a strong law of large numbers for a linear process generated by asymptotically almost negatively random variables in a Hilbert space with this result.
