The meaning of crosswalks and traffic lights in modern society has changed a lot as the enforcement of traffic signal violations has been strengthened. In this paper, we present a new next-generation traffic light method using radar and Can-bus communication methods suitable for the new traffic signal enforcement system. This method is a system that prevents accidents by transmitting information on the entry of a person and a car to a traffic light in a place where a person and a car passing through a mutually invisible traffic light cannot be seen. Since this system has only been developed for a month, it may be somewhat lacking in experimentation. However, in just one month, there have been no incidents except for a few people where the system has been installed.

This paper represent a method of next generation IT fields of embedded systems. we discuss the background why the embedded systems is the importance in the next generation IT fields. Also, we describe the hardware oriented embedded systems, the embedded hardware processor, specified processor. And we discuss the embedded system application fields, i.e. mobile phone application, STB application, telematics fields, home automation, personal digital assistant and so on.

A meaning of power quality has changed, which affects on an environmental change of existing electricity supply markets. Today, it should take both consumers and suppliers into consideration to develop information and communication technology and to increase the use of power and electronic equipments. As a result, it is necessary to develop a system to monitor power quality and to display data. In this paper, a system, as a power quality monitoring equipment, which can use protective replays with progress of microprocessor technology and provide information in the intranet/internet circumstances using web-based architecture is described.

This study is a discussion of business process reengineering for the next generation information system. To be concrete, we analyze and reengineer the current business process in administration of academic, general and research. This reengineering is conformed by 5 steps, as analyzing environmental status that figures out factors of inside or outside (environmental analyzing), analyzing current condition that diagnoses AS-IS process (current situation analysis), establishing information-oriented vision with strategic accomplishing goals accordingly (visioning), deducing detailed improving tasks (defining tasks), and engineering TO-BE process comprehending improving matters (engineering model). This paper shows BPR model for next generation information system.

This paper presents the methods to solve the problem about Power System Protection Program(PROSET). PROSET is a overall program system to protect power system and correct it. In the context of the PROSET, it is so difficult to edit database data when topology is changed. When the renewal of data is performed, all changed values are disappeared. Therefore, it will not be expected to know the present situation by using the information of the databases data. So it is necessary to solve this problem. Solution is copy of the user. Database of GRL,GRZ,KYP2D1,KYD2X1,L90 Relay module were developed. We made a database management system for PROSET, therefore I will show this management system briefly.

This paper studies a system design of testifying next generation convergence network. Next generation convergence network includes such elements as not only various gateway systems interworking with conventional PSTN(Public Switched Telephone Network) but also various protocols communicating between gateway systems and softswitches or gateway controllers. Discussed are an effective system solution to verify functionalities and performance of protocols professing. From such discussion, the study identifies functional blocks and operational flows required for establishing a test system, and then with a basis of these proposes a system architecture. Finally this paper presents system design results and its implemented functional details.

With the spread of COVID-19 infections, the need for next-generation learning management system for undact education is rapidly increasing, and the Ministry of Education is planning future education through the establishment of fourth-generation NEIS. If the fourth-generation NEIS System is well utilized, there are advantages such as providing personalized education services and activating the use of educational data, but a solution to the illegal access problem in an access control environment where strict authorization is difficult due to various user rights. In this paper, we propose a blockchain-based access control audit system for next-generation learning management. Sensitive personal information is encrypted and stored using the proposed system, and when the auditor performs an audit later, a secret key for decryption is issued to ensure auditing. In addition, in order to prevent modification and deletion of stored log information, log information was stored in the blockchain to ensure stability. In this paper, a hierarchical ID-based encryption and a private blockchain are used so that higher-level institutions such as the Ministry of Education can hierarchically manage the access rights of each institution.

Mobile users want to be provided with undisrupted network services when they navigate on the Next-Generation (NG) wireless networks. For that, interlocking with a heterogeneous network is important, but there have been few studies on the method for guaranteeing global mobility. Thus, this paper proposes the Proxy-LMA technique, the mobile IP-based global inter-networking system, to enhance global mobility and interoperability within the Next-Generation (NG) network environment. The purpose of the proposed Proxy-LMA system is to expand the boundary of the mobility with regards to the existing mobility management protocol (PMIPv6 and MIPv6) in order to guarantee global mobility and interoperability within the heterogeneous network environment. The results of the performance evaluation showed that the proposed Proxy-LMA system was more efficient than other methods from the standpoint of signaling cost and delay in the heterogeneous network environment.

This paper presents the methods to solve the problem about Power System Protection Program(PROSET) and describe the database relation and schema with UML. PROSET is a overall program system to protect power system and correct it. In the context of the PROSET it is so difficult to edit database data when topology is changed. When the renewal of data is performed. all changed values are disappeared. Therefore, it will not be expected to know the present situation by using the information of the databases data. So it is necessary to solve this problem. Solution is copy of the user. Only E.R diagram is used to express database schema and relation. So, in this paper, UML(Unified Modeling Language) will be used to express PROSET and database of MCD-H and MDT-H.
