SCADA (Supervisory Control and Data Acquisition) system has been used fur remote measurement and control on the critical infrastructures as well as modem industrial facilities. As cyber attacks increase on communication networks. SCADA network has been also exposed to cyber security problems. Especially, SCADA systems of energy industry such as electric power, gas and oil are vulnerable to targeted cyber attack and terrorism. Recently, many research efforts to solve the problems have made progress on SCADA network security. In this paper, we introduce recent security issue of SCADA network and propose the application of encryption method to Korea SCADA network.

As terrorist organizations like ISIL and Al-Qaeda attack multiple-use facilities such as subways and department stores that many unknown citizens are using, the fear and anxiety are expanding. If international terrorism occurs in Korea, it may attack multiple-use facilities. Therefore, we need to have countermeasures against the attack. However, as the concept of multiple-use facilities has multi-faceted meanings and the scope is wide, there is a limitation in the preparation for international terrorism. In this study, it was tried to find the solution through reviewing the multiple-use facilities related laws. First of all, as the multiple-use facilities related laws were legislated by government organizations according to the necessities, the concept and scope are very inclusive. Therefore, it is possible to have controversies on the scope of the review related to anti-terrorism. Next, the department responsible for the international terrorism is not clear, which can make issue of rights and responsibility. To overcome such limitations, this study tried to set the concept and scope of multiple-use facilities and discussed the issue of the responsible department.

The demand of the care facilities for the elderly will be increased, because of the social changes which desire well organized medical treatment service. However, they have been illogically administrating such as preparing service at living space because of lacking places which provide living service. So the side of administration, it is necessary to have a security and improvement in that kind of needed place. The studies of elderly care facilities have been placing too much emphasis on the living space of the residential facilities and their welfare facilities compare with the service providing place which is ignored just as a part of the living space. This study focus on a situation of elderly care facilities and analyze a service space using in facilities, so it can be applied to service place plan for the future.

The information transfer between the ground facilities and the ground facilities and exchange are necessary for an aircraft and ground facilities so that it is safe, it is economic, an aircraft tan operate an aircraft to the high efficiency until it arrives at the destination location from the stand-by for the fly. Presently, by using the AFTN which is closed network, a communication is made. However, by applying the leading edge communication technology, the aeronautical telecommunication network of the next generation is constructed and it is planning to be managed. Due to this, the ground facilities connected to the foreign network has the security vulnerability by an attack. Therefore, the vulnerability analysis for the safe operational environment build-up at the aeronautical telecommunication network and sorority requirement research are needed.

In the past, conservative concepts have been applied in terms of the characteristic of nuclear power plants(NPPs), resulting in analog-based equipment and closed networks. However, as digital technology has recently been applied to the design, digital-based facilities and communication networks have been used in nuclear power plants, increasing the risk of cybersecurity than using analog-based facilities. Nuclear power plant facilities are divided into a safety system and a non-safety system. It is essential to identify the difference and cope with cybersecurity threats to the safety system according to its characteristics. In this paper, we examine the cybersecurity regulatory guidelines for safety systems in nuclear power plant facilities. Also, we analyze cybersecurity threats to a programmable logic controller of the safety system and suggest cybersecurity requirements be applied to it to respond to the threats. By implementing security functions suitable for the programmable logic controller according to the suggested cybersecurity requirements, regulatory guidelines can be satisfied, and security functions can be extended according to other system requirements. Also, it can effectively cope with cybersecurity attacks that may occur during the operation of nuclear power plants.

The purpose of this research is to help outdoor space planning reflected real needs of apartment residents in the differentiation elements of outdoor space, by using USC trade-off game in three apartment complexes in Seoul. This game method was used to evaluate their preference, reliability of preference degree, satisfaction degree, requirement elements such as improvement, sacrifice, maintenance of present condition, and payment possibility for improving and maintaining present condition, in addition to their preference and payment possibility of differentiation of outdoor space in the apartment complex in the future. From the statical analysis, we found the following results: 1. Reliability of preference degree was valid, inasmuch as the first elements they preferred were the almost same as the last things. 2. Elements of preference were pedestrian ways, pedestrian security facilities, various athletic facilities, and variety and high-class facilities in a play ground. 3. Satisfaction degree of differentiation elements of outdoor space was low not only in total complexes but also in each complex. As a result of analysis, these elements were not satisfied with residents. 4. Most of the differentiation elements of outdoor space in three apartment complexes, except planting traditional trees, were required to improve and maintain present condition. The cost to improve and maintain these elements able to pay by them was about 2.18 million won. Through this result, these elements were not options but prerequisites for planning outdoor space in apartment complexes. 5. In the future preference elements of differentiation of outdoor space in apartment complexes were pedestrian and jogging ways, places with water, various athletic places and facilities, multi-function resting places, green spaces in experiences, pedestrian security facilities, various athletic facilities, variety and high-class facilities in a play ground, and payment possibility for these elements was about 3.20 million won.

The International Ship and Port Facility Security (ISPS) Code which was developed as the main response of the shipping sector to the miserable event of 11 September 2001 came into effect on 1 July 2004. The ISPS Code designed to detect and eliminate security threats affecting ships and port facilities used in international trade will significantly impact not only on the management and operation of the shipping industry but also on maritime law despite the fact that it is the regulatory framework of public law. It is expected that implementing the ISPS Code will contribute to reinforcement of maritime security on the one hand. However, on the other hand, more intensified security inspection and control measures of port states will also cause delay and additional costs which cause uncertainty in allocating security risk and cost between the contracting parties. Therefore, it is desire to insert new security clause dealing with main security issues or adapt existing clauses to new shipping environments to minimize disputes.

There are many attempts to apply AI technology to diagnose facilities or improve the work efficiency of the power industry. The emergence of new machine learning technologies, such as deep learning, is accelerating the digital transformation of the power sector. The problem is that traditional power systems face security risks when adopting state-of-the-art AI systems. This adoption has convergence characteristics and reveals new cybersecurity threats and vulnerabilities to the power system. This paper deals with the security measures and implementations of the power system using machine learning. Through building a commercial facility operations forecasting system using machine learning technology utilizing power big data, this paper identifies and addresses security vulnerabilities that must compensated to protect customer information and power system safety. Furthermore, it provides security guidelines by generalizing security measures to be considered when applying AI.
