개인정보 보호를 위한 통합 컨트롤 타워로서 2020년 8월에 개인정보보호위원회가 출범하였으나 개인정보보호 운영 체계상 몇 가지 문제점이 지적되고 있다. 먼저 우리나라의 개인정보 보호 체계는 공공과 민간을 함께 규율하는 통합법 체계를 가지고 있음에도 불구하고 개인신용정보 보호 기능은 금융위원회가 담당하고, 개인위치정보 보호 기능은 방송통신위원회가 그대로 담당하는 등 보호 기능의 불완전한 통합으로 원활한 개인정보 보호 기능을 하기 어렵다는 지적이 있다. 다음으로 공공부문 개인정보 유출 사고가 증가하고 있음에도 이를 효율적으로 조사할 전문성을 갖춘 인력과 전문 지원기관이 부족한 문제가 있고, 디지털 통상시대를 맞이하여 글로벌 IT 기업의 자국 내 개인정보 침해에 대한 효율적인 대응체계가 부족하여 국민의 개인정보 보호가 약화 될 우려가 있다. 이러한 문제를 해결하고자 해외사례와 문헌들을 검토하여 다음과 같은 방안을 제시하였다. 첫째, 신용정보와 위치정보에 대한 개인정보 보호 감독 기능을 개인정보보호위원회로 일원화 할 필요가 있다. 둘째, 공공부문 개인정보 유출 사고에 대응하기 위해 전문인력 확보와 전문기관 설립 등 전문성 확보가 필요하다. 셋째, 디지털 통상시대에 국민의 개인정보보호를 위한 국내 대리인지정제도 활성화와 국제 공조 체계 구축 필요성을 제기하였다. 이와 같은 개인정보 보호 체계 발전 방안으로 한층 체계화된 개인정보보호가 이루어질 것으로 생각한다.

Korean Industrial Standards for lightning protection system complies with IEC standards. However, the standards are applicable only to buildings and structures more than 20 meters in high. Therefore, it is necessary to determine whether lightning protection system should be installed on structures lower than 20 meters high. This paper proposes an efficient method of assessing risk against lightning of structures lower than 20 meters high. The method suggests simplified lightning protection system and provides selecting an appropriate protection level. The suggested method assumes that structure under assessment has no lightning protection system and there is no person around the structure at the moment of lightning stroke. A simplified method of assessing the risk to human within the structure is developed by adopting the general assessment factor. The selection of a protection level is possible by comparing tolerable risk with physical damage risk caused by a direct lightning. Finally, this paper gives ways to establish surge protection measures when a structure with lightning risk is within a radius of 2km from the assessed structure even if this structure requires no lightning protection system.

As the risk of technical leakage is increasing, technology protection support systems for small and medium-sized businesses have gained attention. This paper analyzed the perception gap of the user and policy-maker regarding technology protection support systems. First, to identify key elements of technology protection support systems and construct measurement factors, interviews with experts are conducted. Then, surveys are conducted to analyze the perception differences between the users and policy-makers. Factor analysis and ANOVA have been utilized to analyze survey results. The result shows that the perception gaps exist in the following areas: management system, cost reduction, copyright protection, customer satisfaction, leakage prevention, and awareness. To enhance the effectiveness of technology protection support systems, this paper suggests technology protection support systems should be customized in terms of the company's size and type of busines.

HVDC protection setting is difficult to be calculated analytically because of its strong nonlinearity. The currently used setting method is based on the empirical setting of previous projects and then verified by digital simulation. It entails a huge workload and low efficiency. To facilitate protection setting, this paper systematically summarizes the HVDC protection characteristics and then presents a classification of HVDC protections according to the protection principles. On the basis of the fault quantities, a novel setting procedure suitable for travelling wave protection, derivative and level protection, and differential protection is proposed. The proposed procedure is illustrated and verified in detail with the example of travelling wave protection. An HVDC protection setting system that has the functions of automatic protection setting and data management is developed utilizing the C# programming language.

In this Paper, We are going to propose the fire protection system with using CAN(Controller Area Network). The larger, higher and deeper buildings are, the more dangerous people are when fire happens. We are aware of the problems of prior Fire protection system. Therefore, we construct embedded system based on CAN communication that is capable of N:N communication, and build independent Fire protection system.

This paper presents a new protection concept to achieve the adaptive optimal function by introducing the multi-agent system technology. Making each relay an agent which consists of relay agent module and coordinator module, each agent works autonomously to improve protection capability by cooperating with other agents. It is applied to the overcurrent protection system of the industrial power system in order to show the feasibility of the proposed methodology.

The digital systems such as PLC or DCS have been applied to non-safety systems of nuclear power plants because of many difficulties in using analog systems. Nowadays, digital systems have been applied to safety systems of the plants such as reactor protection system. One of the main advantages of digital systems is applicability of automatic testing methods to the systems. The protection system requires high-reliability and high-availability because it shall minimize the propagation of abnormal or accident conditions of nuclear power plants. The calculation of reliability and availability of systems depends on the maintenance period of the system. In general, the maintenance period of the protection system is one-month in case of the manual test. However, the cycle of test can be shortened in several hours by using automatic periodic testing. The reliability and availability of the system is better when test period is shortened because the reliability and availability is inverse proportion to the test period. In this research, we developed the automatic periodic testing method for KNICS Reactor Protection System, which can test the system automatically without an operator or a tester. The automatic testing contained all functions of reaction protection systems from analog-to-digital conversion function of the bistable Processor to the coincident trip function of the coincident processor. By applying the automatic periodic testing to reaction system, the maintenance cost can be cut down and the reliability can be increased.

In this paper, physical scale modeling was employed to identify the configurations of ICCP system and the electric field signatures. Computational boundary element modeling technique has been used to simulate the performance of the CP system and to predict the associated electric fields signatures. The optimization methods combined with the computer models and physical scale modeling will be presented here, which enable the optimum system design to be achieved both in terms of the location and current output of the anode but also in the location of reference electrodes for impressed current cathodic protection(ICCP) systems. The combined methodology was utilized to determine optimal placement of ICCP components (anodes and reference electrodes) and to evaluate performance of ICCP system for the 2%, 10% and 14% wetted hull coatings loss. The objective is to design the system to minimise the electric field while at the same time provide adequate protection for the ship. The results show that experimental scale modeling and computational modeling techniques can be used in concert to design an optimum ICCP system and to provide information for quickly analysis of the system and its surrounding environment.
