국제적인 규제와 정부차원의 지원과 관리가 이뤄지고 있음에도 불구하고 기관 등에서는 여전히 소프트웨어자산에 대한 인식과 관리 소홀의 문제점을 안고 있다. 이는 관리해야 할 소프트웨어자산 범위의 모호함과 소프트웨어의 특성상 복사 및 설치가 쉽고 눈에 보이지 않아 관리 자체가 어렵기 때문이다. 즉 기업내 소프트웨어관리자는 구매부터 조달, 배포, 유지, 처분까지의 전체적인 소프트웨어 라이프사이클의 각 단계별로 수시로 변화되는 정보를 정확히 일치시키기가 쉽지 않다는 문제점이 있다. 따라서 이를 해결하기 위해서는 점검용 시스템 개발이 필요하며 점검용 시스템 성능향상을 위해 소프트웨어의 권리관리 정보의 표준화 및 레지스트리 정보 활용이 필요하다.

While temporary construction work applies to a temporary facility, it has a high use frequency during the construction period accounting for around 10% of the construction cost, it requires systematic management. However, construction inspection information of temporary construction work often has no special specification in the design documents and specification items, with the items on various standards also being formidable. Because of this, related inspection are likely to be performed inefficiently with a high probability for occurrence of human errors when quality inspection is conducted for the temporary construction work. In the present study, therefore, apply to the electronic operation support system capable of supporting implementation of inspection of providing related information for the contemporary construction work. To achieve this, a prototype is developed by using IDEF0 to identify information flow by process and organizing EPSS-based quality inspection Task. And then, efficiency of the quality inspection and information accessibility for temporary construction work are to be improved by verification method of Sample Project.

Currently, most procedures in domestic facility management systems are performed by hand. However, these manually operated facility management systems involve critical limitations, such as a waste of manpower to store collected data into a database, intentional or accidental loss of data consistency (mainly due to a lack of the ability to recognize and deal with frequent changes of facility status in realtime), and so on. To overcome the limitations of such manually operated facility management systems, the following capabilities must be supported. First, the changes in facility status must be recognized in realtime. Second, the data collection process must be secure and reliable to prevent fabrication of collected data and preserve data integrity. Third, the data collection devices must be portable to help the manager collect data about their facilities. To address these problems, we design and implement a novel facility management system using portable RFID, which is designed to support these functionalities and thus help reduce administrative costs. Through extensive experiments, we observed that our system improved the accuracy and reliability of facility check process and helped cut administrative costs by significantly reducing failure frequency.

This study applied SONAR(Sound Navigation And Ranging) to the inspection and evaluation of underwater structures. Anactual river bridge was chosen for inspection and evaluation. SONAR and an optical camera were operated together to analyze the underwater image of the bridge. SONAR images were obtained by various methods to remove the environmental variables from the field experiment, and it was confirmed that the reliability of detecting damaged areas on piers was decreased when using SONAR alone. The SONAR equipment and the optical camera can be used simultaneously to overcome the limitations of SONAR in inspecting underwater structures.These results can be used as basic data for the development of similar technologies for underwater structure inspection.

Organizations and customers lose if business activities we discontinued by an incident of information systems under the current business environment because they pursue real time enterprise and on demand enterprise. The loss includes the intangible decline in brand image, customer separation, and the tangible loss such as decrease in business profits. Thus. it is necessary to have preparedness in advance and mitigation for minimization of a loss due to the business discontinuity and information system's operational risks. This paper suggests the mitigation model for minimizing the incidents of disk unit in information system's operational risks. The model will be represented by a network model which is composed of the three items as following: (1) causes, attributes, indicators of an operational risk, (2) a periodic time through an analysis of historical data, (3) an index or a regulation related to the examination of causes of an operational risk.

Various types of robots running on power transmission lines have been developed for the purpose of line patrol monitoring. They usually have complex mechanism to run and avoid obstacles on the power line, but nevertheless did not show satisfactory performance for going over the obstacles. Moreover, they were so heavy that they could not be easily installed on the lines. To compensate these problems, flying robots have been developed and recently, multi-copter drones with flight stability have been used in the electric power industry. The drones could be remotely controlled by human operators to monitor power distribution lines. In the case of transmission line patrol, however, transmission towers are huge and their spans are very long, and thus, it is very difficult for the pilot to control the patrol drones with the naked eye from a long distance away. This means that the risk of a drone crash onto electric power facilities always resides. In addition, there exists another danger of electromagnetic interference with the drones on autopilot waypoint tracking under ultra-high voltage environments. This paper presents a patrol monitoring plan of autopilot drones for power transmission lines and its field tests. First, the magnetic field effect on an autopilot patrol drone is investigated. Then, how to build the flight path to avoid the magnetic interference is proposed and our autopilot drone system is introduced. Finally, the effectiveness of the proposed patrol plan is confirmed through its field test results in the 154 kV, 345 kV and 765 kV transmission lines in Chungcheongnam-do.

With the increase in the types of information systems managed by public institutions and companies, a security certification system is being implemented in Korea to quickly respond to vulnerabilities that may arise due to insufficient security checks. The korea security evaluation system, such as ISMS-P, performs a systematic security evaluation for each category by dividing the categories for technical inspection items. NIST in the United States has developed SCAP that can create security checklists and automate vulnerability checks, and the security checklists used for SCAP can be written in OVAL. Each manufacturer prepares a security check list and shares it through the SCAP community, but it's difficult to use it in Korea because it is not categorized according to the korea security evaluation system. Therefore, in this paper, we present a mechanism to categorize the OVAL definition, which is an inspection item written in OVAL, to apply SCAP to the korea security evaluation system. It was shown that 189 out of 230 items of the Red Hat 8 STIG file could be applied to the korea security evaluation system, and the statistics of the categorized Redhat definition file could be analyzed to confirm the trend of system vulnerabilities by category.
