Even though newly formed schools do struggle to strengthen their security in safety, existed schools have limitations for active response against natural disaster. From analyzing the results of accident cases and states in misfortune and the safety supervision of school facilities, it is said that damages by wind, flood and fire are typical types of disaster accidents. Also, according to the basic law of misfortune and the safety supervision, it emphasizes education, training, and actions that prevent from being a victim of natural disaster. In terms of these finding, establishing disaster safety organization, control system and having students an opportunity to learn how to response against disaster should be critical component in managing disaster safety of school facilities.

Sludge incineration facilities are socially recognized as a hate facility. Therefore, a careful deodorization plan must be established. Therefore, the incineration facility must conduct research on odor ventilation. In this study, a odor diffusion simulation in an incineration facility was conducted and analyzed. In particular, research was carried out on carry-in rooms, pre-treatment rooms, and storage facilities for crops, which are expected to rapidly spread odor. As a result, ammonia 1.62, hydrogen sulfide 0.63, and acetaldehyde 0.73 were found in the transfer room. In addition, pretreatment rooms and stencil storage facilities were found to be lower than regulatory standards.

A form of consumption has been changed to a form of pursuing rather qualitative sides than quantitative sides according to an improvement of the living level followed by an increase in national income and to an increase in women's advance to society in modern society. The above change had a lot of effects on children play space, a subsidiary means within commercial facilities. However, partial children play facilities have steady children injury cases by a lack of safety management facilities. Therefore, the study investigated indoor children play facilities installed in large-scale distribution stores as department stores and discount stores out of commercial facilities in Seoul. The study investigated actual conditions and collected picture data with a checklist drawn up on the basis of the safety management standard for three months from April, 2008 to June, 2008 by visiting five places under cooperation. The purpose of the study was to grasp actual conditions of safety management of play space within commercial facilities through the contents and picture data of the investigated checklist and to offer basic data in the side of safety management of commercial facilities and various indoor children play spaces by proposing security measures for the problems.

The utilization of underground space has recently increased with the complication of road, the rise of the land price, and the development of green technology. Underground space ranges from classical excavations to subway, underground cities, and shopping malls where there are crowds of people. At this time, government has spent a lot of money in installing various types of safety facilities for preparations of increasing potential disasters. Therefore, an effective facility management system is required. In this paper, we propose an information retrieval process to effectively extract the facilities' information based on the ontology and spatial analysis in underground space. The ontology-based searching supports hierarchical and associated results as well as knowledge sharing with hierarchy concepts. The spatial analysis based searching has "Buffer" and "Near" functions to operate on a map without understanding any property of the facility information.

This paper propose G-code and G-Pedigree system that are development based on the e-Pedigree and EPC, and RFID solutions for logistics management is proposed. The proposed G-Pedigree system to include the forward logistics and reverse logistics all logistics and management systems are appropriate for the event, with security features, security and accessibility of critical data was strengthened. The proposed G-code systems and the EPC code of the existing RFID readers, tags can be applied to, the more you can manage the logistics-related information.

Traditional Cloud Computing would be unable to safely host IoT data due to its high latency as the number of IoT sensors and physical devices accommodated on the Internet grows by the day. Because of the difficulty of processing all IoT large data on Cloud facilities, there hasn't been enough research done on automating the security of all components in the IoT-Cloud ecosystem that deal with big data and real-time jobs. It's difficult, for example, to build an automatic, secure data transfer from the IoT layer to the cloud layer, which incorporates a large number of scattered devices. Addressing this issue this article presents an intelligent algorithm that deals with enhancing security aspects in IoT cloud ecosystem using butterfly optimization algorithm.

In this paper, we have proposed a design for security network system passing through the non-security network which is commonly used for various networking services. Based on the security requirements which are assumed that the large classified data are bi-transmitted between a server and several terminals remotely located, some application methods of security techniques are suggested such as the network separation technique, the scale-down application technique of certification management system based on the PKI(Public Key Infrastructure), the double encryption application using the crypto-equipment and the asymmetric keys encryption algorithm, unrecoverable data deleting technique and system access control using USB device. It is expected that the application of this design technique for the security network causes to increase the efficiency of the existing network facilities and reduce the cost for developing and maintaining of new and traditional network security systems.
