  • Network administrator recognizes the abnormal phenomenon in the managed network by using the alert messages generated in the security devices including the intrusion detection system, intrusion prevention system, firewall, and etc. And then the series of task, which searches for the traffic related to the alert message and analyzes the traffic data, are required to determine where the abnormal phenomenon is the real network security threat or not. There are many alert messages to have to inspect in order to determine the network security situation. Also the much times are needed so that the network administrator can analyze the security condition using existing methods. Therefore, in this paper, we proposed an efficient method for analyzing network security situation using visualization. The proposed method monitors anomalies occurred in the entire IP address's space and displays the detail information of a security event. In addition, it represents the physical locations of the attackers or victims by linking GIS information and IP address. Therefore, it is helpful for network administrator to rapidly analyze the security status of managed network.

  • Background : With the CQI concepts, which emphasize doing the right things right the first time, we tried to enhance the timely completion of medical records by changing the review process from retrospective method to concurrent one. Methods : Against the current retrospective QA activity, Medical record administrator did the concurrent QA of the inpatient medical records with the deficiency sheets. One general surgery ward was chosen as a trial one. The deficiency rate of the medical records of the discharged patients was compared before and after the enforcement of the system. Job analysis of the medical record departments was done about four tertiary care hospitals located in Seoul to estimate the cost and the time consumed by current system. Results : There was a little improvement in the completion rate of the medical records after the trial. The new system was effective. And job analysis showed that much money and time were wasted by current retrospective feedback system. Conclusion : Though the result was not so satisfactory, it should be considered that this test was a voluntary one and the interns and residents were not forced to complete the medical records during this trial period. If there be any strong motivation to complete the medical record in time, this system is sure to be succeed. As the DRG system requires the concurrent review of the medical records to confirm severity of the patient's illness and to assure the timely discharge, it is desirable to enforce this method with the DRG system together. DRG coding and reducing deficiency rate of the medical records can be accomplished simultaneously.

  • VNC is one of popular thin client computing systems, which supports cross-platform remote control using the RFB protocol. Unfortunately, since VNC does not provide functions specially designed for collaboration, it is difficult to collaborate effectively through the remote control function of VNC. In this paper, we present the extension of the UltraVNC server and the JavaViewer client which are one of open-source VNC systems. For effective real-time collaboration, the extended VNC provides three kinds of access authorities to control the collaboration server: administrator, worker, and spectator. The administrator can control the access authorities of the users through the access control tool, newly provided in the extended JavaViewer. The workers can access the resources of the remote server, whereas the spectator cannot handle those remote resources, only monitoring the remote server. In addition, the extended VNC provides the one-click connection facility for easy connection to the collaboration server from many collaboration participants.

  • Purpose: This study was conducted to develop a web-based business management system to ensure the efficient operation and transparent management of government-subsidized agricultural machinery rental businesses. Methods: An MS_SQL2000 database management system (DBMS) solution was utilized in the system for high system compatibility and integrated management. This system was targeted to be compatible with Internet Explorer 6.0 or later and to ensure security and seamless web operations. The system administrator is able to manage a fleet of agricultural machinery, including various inventory codes, release and return, fleet registry, and business performance. Users (farmers) may search the database of rental machinery and reserve them. Results: With respect to rental reservations, the system administrator can manage the fleet by setting the rental status to Approved, Released, or Returned. Through the web, the administrator can also create a database that includes machinery specifications, features, and rental rates. In addition, business performance data can be analyzed using a diverse array of tools to streamline the rental business. Without having to go to the rental office, users can save time and money by searching for and renting agricultural machinery through the information available on the website, including availability, specifications, and rental fees. After deploying the system, the time required to analyze monthly performance and create reports was dramatically reduced from 20 days per person to one day per person. Conclusions: Since 2014, AMRB has been installed and is operating in agricultural machinery rental businesses in 31 cities and counties in South Korea. This study recommends continued expansion and dissemination of AMRB for the systematic and efficient management of agricultural machinery rental businesses.

  • The system used in the laboratory of chemistry and medical is management only by measuring the temperature inside the reagent management within and recording in handwriting. When you hold the reagent, it can not recognize in real time the problems that occur in the interior, an accident occurs. you can not find a use record reagent storage, a problem with the management of an efficient reagent can be generated. In this paper, we propose a reagent management system that leverages the embedded boards and sensors in the laboratory reagents effectively manage to resolve it. As a result, Converting the information of the reagent to the data using the NFC, the administrator can identify the reagent user to register and manage hazardous reagents. Converted by using the NFC information of the reagent to the data, the administrator can identify the reagent user to register and manage hazardous reagents, temperature, humidity, so that it can be controlled by utilizing the VOC sensor to. Also it is passes the message to the administrator in the event of a particular risk situation. This is believed to enable the effective administration in a laboratory reagent.

  • Because the log information provides some critical clues for solving the problem of illegal system access, it is very important for a system administrator to gather and analyze the log data. In a Linux system, the syslog utility has been used to gather various kinds of log data. Unfortunately, there is a limitation that a system administrator should rely on the services only provided by the syslog utility. To overcome this limitation, this paper suggests a syslog agent that allows the system administrator to gather log information for file access that is not serviced by syslog utility. The basic concept of the suggested syslog agent is that after creating a FUSE, it stores the accessed information of the files under the directory on which FUSE has been mounted into the log file via syslog utility. To review its functional validity, a FUSE file system was implemented on Linux (Ubunt 14.04), and the log information of a file access was collected and confirmed.

  • In this paper, using the Android App to remote database monitoring system is proposed. Existing remote database monitoring scheme CS(Client / Server) based. Conventional CS based systems are space constraints and a plurality of administrator to access the database at that degrade performance disadvantages. The advantage of the proposed system first, because the web -based interface allows the application program, and also the ease of maintenance, through a web browser, if you have Internet access anytime, anywhere environment without restrictions of time and space monitoring. Second, the proposed system because the App -based technology due to an increase in connection session and query execution does not affect the performance of your database. Third, if there is a problem with the remote database through which social networks immediately notify the administrator of the smartphone in real time so that the administrator can identify the problem.

  • The implementation of Daedongbeop of Gyeonggido after throne of Gwanghaegun, the Daedongbeop of Gangwondo afterthrone of Injo, and the Daedongbeop of Chongcheongdo and Chollado after throne of Hyojong were in expectation of new kings the greatest Governing Administrator who tried to improve the hard life of the people, It was possible because there was a great effort. However, after throne of these three kings, the enactment of the Daedongbeop is a major crisis. The difference of the crisis related to enforcement was that the enforcement of the Daedongbeop of the Gwanghaegun and the Injo was carried out immediately after the enforcement decision was made but soon it was put into a crisis of abolishment and the Chungcheongdo and Chollado provincial Daedongbeop encountered extreme opposition before the enforcement and it has been carried on continuously since the end of the abolition crisis. In this study, we examined the efforts of the Governing Administrator who succeeded in the enactment of the Daedongbeop for the peaceful life of the people, with the throne of these three kings and the expectation of the new king. In the case of at the time of Gwanghaegun, Hanbekgyeom, LeeWonik, and Hwangshin, Joeik and LeeWonik at the time of Injo, and Kimyuk at the time of Hyojong were common people who have tried to improve the troubles of the people. They did not focus only on the theoretical interpretation of Neo-Confucianism, but on the basis of the interpretation, they demonstrated the power of the Governing Administrator practicing the right politics for the people in reality. The result is policy formulation and enforcement for the implementation of the Daedongbeop.
