Purpose: The purpose of this study is to design a x-ray screening rating system to improve X-ray screening ability, which is a core job competency of security screener at Incheon International Airport, and to verify its effectiveness through empirical analysis to suggest ways to improve the level management system. Methods: In this study, the effectiveness of the research model was analyzed using T-test tests for effect analysis based on the empirical analysis results derived through the competency evaluation model, the screening rating system. Results: The results of this study are as follows. The average score for regular education before the implementation of the x-ray screening rating system was 94.1 points, but after the implementation of the x-ray screening rating system, the average score for regular education was 95.5 points, an average of 1.4 points increased. In addition, the proportion of those with 95 or more points classified as high scorers also increased significantly from 51.1% to 69.3%. Conclusion: The X-ray screening rating system of security inspectors will systematically manage the level of screening ability, which is a key job competency, and play a strong role in improving competency, while preventing security accidents through early identification and intensive training of level-lowers.

The purpose of this study verify to the effect of applying the X-ray screening ability rating for security screening persons in Incheon International Airport. Data collected through a evaluation score of 1,034 security screening persons in Incheon International Airport. Data analysis performed using paired sample t-test. The research results found that it was a statistically significant difference pre-test and post-test applying the X-ray screening ability rating. In this article, we asserts that the X-ray screening ability rating is effective in improving the X-ray screening ability of security screening persons. This paper contribute to the academic expansion of motivation theory and self-determination theory. This study is valuable as a preemptive empirical research that provides practical implications about the application of X-ray screening ability rating for security screening persons.

This article explores on the deploying of game rating system in the context of whole game governance. Rating system is critical apparatus of game policy because it works as a kind of counterweight between different actors. We analyse to apply the three form of governmentality by Faucault. Rating system can be commonly considered as security mechanism. Korean rating system has hoped to be so but its effect was not actually. We should see why that system evolve to disciplinary mechanism, not toward security mechanism. Sound governance shows to be ensure all actors to participate its procedures practically, through constituting more rich discourse.

SInce 2000, Instrumentation and Control(I&C) systems of Nuclear Power Plant(NPP) based on analog technology began to be applied to the digital technology. NPPs under construction in the country with domestic APR1400 I&C system, most devices were digitalized. Cyber security of NPP I&C systems has emerged as an important issue because digital devices compared to the existing analog equipment are vulnerable to cyber attacks. In this paper, We proposed the risk rating process of cyber security threats in NPP I&C system and applied the proposed process to the Reactor Protection System(RPS) developed through Korea Nuclear Instrumentation & Control System(KINCS) project for evaluating the risk of cyber security threats.

With an increasing awareness of information security, the market demand for better information security goods and services causes shortage in well trained information security manpower. This study analyzes the priorities of the options available to the qualitative information security manpower training policy. The analysis is conducted through four hierarchies: goals, criteria, sub-criteria and alternatives for each of which priorities are developed through the rating approach of the Analytic Hierarchy Process (AHP). 3 criteria and 8 sub-criteria are involved in the four hierarchies. The analysis result indicates that the fundamental information security technology is the most desirable.

This paper suggests the method that forecasts Dynamic Line Rating (DLR). Thermal Overload Risk Probability (TORP) of the next time is forecasted based on the present weather conditions and DLR value by Monte Carlo Simulation (MCS). To model weather elements of transmission line for MCS process, this paper will propose the use of statistical weather models that time series is applied. Also, through the case study, it is confirmed that the forecasted TORP can be utilized as a criterion that decides DLR of next time. In short, proposed method may be used usefully to keep security and reliability of transmission line by forecasting transmission capacity of the next time.

Currently, obtaining information about the housing studies through the internet web sites is one of the outstanding mediums. Those are of the housings, architecture, interior design, furniture products, hotels and its journals, etc., and out of all those informations are the highly expected value of use. But. it may causes the public users to experience a negative effect, because many of those informations provided on the internet web sites related to the housing studies/informations are not providing an equal quality of information. And measuring the quality is also not easy. This study focuses on the establishment of evaluation criterion for the housing information-related internet web sites. In such a vein, it proposes a clear model to evaluate the information qualities with the 43 questionnaires / examining items. To test the questionnaires/rating items, the analysis has been implemented which has shown the reciprocal effect between the 2 major factors. One major factor with 4 variables on the information searches are (1) the accuracy/reliability of contents and techniques, (2) the design of a picture and communication, (3) the readability and security, and (4) the security of private information, and the other factor with 3variables on the additional services are (1) the diversities of contents and ease of orderings, (2) the abilities of search and e-mail, and (3) the events and after services. This study/rating model will provide the users with a fundamental material in evaluating the quality of housing information on the internet web sites.

This Analyzed case study of measuring displacement, implemented laboratory investigation, and in-situ testing in order to interpret ground subsidence risk rating by excavation work. Since geological features of each country are different, it is necessary to objectify or classify quantitatively ground subsidence risk evaluation in accordance with Korean ground character. Induced main factor that could be evaluated and used to predicted ground subsidence risk through literature investigation and analysis study on research trend related to the ground subsidence. Major factors of ground subsidence might be classified by geological features as overburden, boundary surface of ground, soil, rock and water. These factors affect each other differently in accordance with type of ground that's classified soil, rock, or complex. Then rock could be classified including limestone element or not, also in case of the latter it might be classified whether brittle shear zone or not.

The game rating system of Korea has many issues in terms of 'censorship' and 'ambiguity', and has been pointed out as a factor that hinders industrial development. Although the Ministry of Culture, Sports and Tourism and other related organizations have made various efforts, it still seems to require more academic discussion. Therefore, in this study, the limitations of game rating system are reviewed, and the systems of foreign countries are analyzed to suggest the improvement direction.

Recently security related attacks occur in very diverse ways, aiming at people who operate the system rather than the system itself by exploiting vulnerabilities of the system. However, to the our best knowledge, there has been very few works to analyze and strategically to deal with the risks of social engineering attacks targeting people. In this paper, in order to access risks of social engineering attacks we analyze those attacks in terms of attack routes, attack means, attack steps, attack tools, attack goals. Then, with the purpose of accessing the organizational risks we consider the characteristics and environments of the organizations because the impacts of attacks on the organizations obviously depend on the characteristics and environments of the organizations. In addition, we analyze general attack risk assessment methods such as CVSS, CWSS, and OWASP Risk Rating Methodolog. Finally, we propose the risk access scheme of social engineering attacks for the organizations. The proposed scheme allows each organization to take its own proper actions to address social engineering attacks according to the changes of its environments.
