In accordance with information security compliance and security regulations, there is a need to develop regular and real-time concepts for cyber-infringement attacks against network system vulnerabilities in branch and periodic forms. Vulnerability Analysis Analysis It is judged that it will be a countermeasure against new hacking attack in case of concept validation by interworking with TOOL. Vulnerability check module is standardized in event attribute management and ease of operation. Opening in terms of global sharing of vulnerability data, owasp zap / Angry ip Etc. were investigated in the SIEM system with interlocking design implementation method. As a result, it was proved that the inspection events were monitored and transmitted to the SIEM console by the vulnerability module of web and network target. In consideration of this, ESM And SIEM system In this paper, we propose a new vulnerability analysis method based on the existing information security consultation and the results of applying this study. Refer to the integrated interrelationship analysis and reference Vulnerability target Goal Hacking It is judged to be a new active concept against invasion attack.

The need for an environmental monitoring system that obtains and provides environmental information in real time is increasing. In particular, in the case of water quality management in public waters, regular management must be conducted through manual and automatic measurement by law, and air pollution also requires regular measurement and management to reduce fine dust and exhaust gas in connection with the realization of carbon neutrality. In this study, we implemented a system that can measure and monitor water pollution and air pollution information in real time. A hovercraft capable of moving on land and water simultaneously was used as a measurement tool. Water quality measurement and air pollution measurement sensors were installed on the hovercraft body, and a communication module was installed to transmit the information to the monitoring system in real time. The structure of a hovercraft for environmental measurement was designed, and a LoRa module capable of low-power, long-distance communication was applied as a real-time information transmission communication module. The operational performance of the proposed system was confirmed through actual hardware implementation.

기존의 수동적인 차량관리 시스템은 관리자가 정해진 위치에 상시 대기하여 관리를 해주어야 하며 아날로그 녹화 시스템의 화질저하와 저장공간의 부족이라는 단점이 있으므로 생산성이나 관리적으로 크게 비효율적이다. 본 논문에서는 이러한 아날로그적인 방법을 탈피하여 영상처리 기법을 이용해 보안카메라에서 받아온 영상정보를 이용해 차량정보를 파악하고 실시간으로 처리하며 Web이나 PDA등 디지털 이동매체에 접속하여 이동환경에서 활용할 수 있도록 통합 시스템을 구축하는 것을 제안한다.

Traffic volumes are the important basic data which are directly used for transportation network planning, highway design, highway management and so forth. They are collected by two types of collection methods, one of which is the continuous traffic counts and the other is the short duration traffic counts. The continuous traffic counts are conducted for 365 days a year using the permanent traffic counter and the short duration traffic counts are conducted for specific day(s). In case of the continuous traffic counts the missing of data occurs due to breakdown or malfunction of the counter from time to time. Thus, the diverse imputation methods have been developed and applied so far. In this study the applied exponential smoothing method, in which the data from the days before and after the missing day are used, is proposed and compared with other imputation methods. The comparison shows that the applied exponential smoothing method enhances the accuracy of imputation when the coefficient of traffic volume variation is low. In addition, it is verified that the variation of traffic volume at the site is an important factor for the accuracy of imputation. Therefore, it is necessary to apply different imputation methods depending upon site and time to raise the reliability of imputation for missing traffic values.

To investigate the effect of the midsummer drainage method on growth and lodging characters, Dongjinbyeo was direct seeded on dry paddy field under 4cm of soil depth at May 1 by seeding machine. Three kind of drainage methods were treated such as, once in 20day, towice in 20, 30 days and 3 times 20, 30, 40 days after flooding. As increase the drainage times, the culm and internode length were shorter, culm wall of 4th internode was thicker, breaking weight was heavier, height of center weight was lower, lodging index was reduced, and dry weight of root was increased. Field lodging occured seriously at none drainage but didn't, with two or three times of drainage. Grain yield was not shown significantly different compared with constant flooding irrespective of midsummer drainage times. Therefore two or three times of midsummer drainage could be recommended as the effective water management for the reduction of lodging occurance in direct seeding culture on dry paddy field.

Our society has evolved into a fully connected society in a mixed reality environment enabling various knowledge sharing / management / control / creation due to the expansion of broadband ICT infrastructure, smart devices, cloud services and social media services. Therefore cyber threats have increased with the convenience. The society of the future can cause more complex and subtle problems, if you do not have an effective response to cyber threats, due to fusion of logical space and physical space, organic connection of the smart object and the universalization of fully connected society. In this paper, we propose the strategy to build knowledge-base as the basis to actively respond to new cyber threats caused by future various environmental changes and the universalization of fully connected society.

The facility safety management in Korea does not secure efficiency as a safety management that is not constructed a maintenance manual. As such, disaster dangerous facilities are at a great danger for disaster occurrence. Accordingly, this study introduced revised requirement and revised level of requirement to field attendants to explore domestic facility safety management system, and set up and suggested a revised plan through brainstorming and attendants of central management institutions. This study is of importance that it reflects field attendants and attendants of central management institutions, suggests specific alternatives for realization to improve national level of institutional improvement.

Web Information Systems have many static HTML documents and dynamic CGI application programs. A hyperlinked information environment on Web systems include lots of mutually referenced documents. This cause problems of data consistency in a intra-document and among inter-documents. To solve the problems, we propose a management method of Web system which have hierarchical information structure, and an unified problem-solving approach. We construct a large scale practical Web system based upon the proposed architecture. The proposed results can provide many advantage to WebMasteters.
