The control laws for cart-pole system are studied to see the schemes on which the control laws are made. Also, the odd symmetry of the relation between the output of the control laws and the system state vector is observed. Utilizing the symmetry in quantizing the system state variables and implementing the control laws into look-up table is discussed. Then, a CMAC is trained for a nonlinear control law for a cart-pole system such that the symmetry is conserved and its learning performance is evaluated. It is found that utilizing the symmetry is to reduce the memory requirement as well as the training period while improving the learning quality in terms of preserving the symmetry.

This study aims to stratify consumer market evaluation items from the Consumer Decision Journey(CDJ) perspective and understand the relationship between laws/systems and consumer orientation through the Korea Consumer Agency's '19 Korea Consumer Markets Evaluation Indicators. This study divided consumer market evaluation items into the selection comparison stage, selection decision stage, and post-purchase experience stage. And present a model that stratified the relationship with consumer orientation of laws/systems and verified using the CDJ model's experience as a control variable. Studies have shown that the relationship between the consumer market evaluation index that evaluates consumer orientation can be stratified according to the consumer decision-making stage and positively affects the relationship with consumer orientation of laws/systems. In addition, the impact of consumer market evaluation variables (reliability, and price) on the consumer orientation of laws/systems was different depending on the presence or absence of consumer damage experience.

The Maglev Train System in Korea has been developed as a type of Light Rail Transit systems meanwhile. LRT systems which is a type of Urban Railway System, has been standardizing and some of them are prescribed but the Maglev System is not in the law Along with planning the Urban Maglev Train Commercialization Project in recent time additionally, we reviewed the contents of the laws for the commercialization of the system, and emerged the way to revise the relative laws.

Having Efficient Contracting Laws and Regulations is one of the critical success factors for SI (System Integration) industry growth. This paper explores problems in contracting systems for SI business. Two perspectives have been used in this analysis. One is on law itself perspective, the other is on industry growth perspective. A comprehensive survey on contracting practices has been done, and the structure of SI industry has been analysed. Also, characteristics of SI contracting processes have been analysed. A framework for efficient contracting laws and regulations for SI industry has been discussed based on the characteristics of SI business and SI industry. Future research will be needed to expand the current framework and to examine the effectiveness of the proposed framework.

Until now, many guidance laws have been developed. They mainly used the classical tail-pursuit guidance method based on geometric angle information, the proportional navigation method based on the line of sight(LOS) rate, and the optimal guidance law based on optimal control theorem. In the augmented guidance law, target acceleration information and autopilot characteristics are added the guidance command. In this study, new guidance laws considering geometric angle are proposed. Two guidance laws are developed for the midcourse guidance law, and a guidance law is developed for the terminal guidance respectively. The proposed guidance laws utilize the LOS rate and the geometric angle information simultaneously. In the midcourse guidance, the guidance command is ...

In this paper, we consider the problem of designing decentralized sliding mode static output feedback control laws for a class of large scale systems with mismatched uncertainties. We derive a sufficient condition for the existence of a linear switching surface in terms of constrained linear matrix inequalities(LMIs), and we parameterize the linear switching surfaces in terms of the solution matrices to the given constrained LMI existence conditions. We also give an LMI-based algorithm for designing decentralized switching feedback control laws. Finally, we give a design example in order to show the effectiveness of our method.

In this paper, two side-attack guidance laws for an underwater vehicle are considered. In order to find the guidance command, we first make use of the optimal guidance law with terminal impact angle constraint. Secondly, the optimal solution of tracking problem is used. This paper shows some brief theory which is used in deriving the side-attack guidance laws, and the method of computing these guidance laws. Simulations on underwater vehicle for a constant moving target prove that the suggested side-attack guidance laws have enhanced side attack performance over the optimal guidance law with miss distance weighting only. Furthermore, from simulation results. we conclude that the guidance law using the optimal solution of tracking problem is more efficient for the side-attack guidance than the optimal guidance law with terminal impact angle constraint.

Recently, various platforms utilizing blockchains have appeared. In order to develop the blockchain, it is required to improve related laws and institutions. In this respect, we analysis of the laws and systems related to domestic blockchains, draw out the limitations, and suggest directions for improvement. The research method was analyzed the literature and related laws through literature review. It is difficult to analyze the whole law and system at one time, so we examined the necessary laws and systems to revitalize the blockchain. It is confirmed that legal improvement is needed on the scope of electronic transactions and electronic financial transactions, electronic commerce, digital signatures, import and export, personal information protection, blockchain industry promotion and research. Through this, we expect a balanced development of effective blockchain revitalization and protection of national fundamental rights. Individual studies on the legal provisions and systems for each item in the future can be conducted.
