Personal Information Article2 defines personal authentication information, secret information, bio information for personal information and it is stipulated under article29 that the one who have duties must take adequate technological, administrative, physical measures to prevent from illegal reading and sneaking. Also it is stipulated under information communication network law28(1), enforcement regulation9, Korea Communications Commitee notice. To satisfy this, the one who have to take security actions of personal information are required to take technological measures and establish positive measures to continuously manage it.The insurance of technological security is possible by encryption of personal information, secure management and operation of encryption key,taking personal information security level of providin access control of personal information reading and audit.In this paper, we will analyze various technologies of personal information encryption which are essencial component in technological security measuresof personal information. This paper will help choose which technological measures you should take in personal information security.

From the perspective of the artist who produces modern ornaments, I wanted to see the future of modern ornaments in the hyperconnected era. I would like to find a practical way of converging information communication technology, which is one of them, and applying nfc tag among them. For the practical approach, after looking at the actual examples of commercial ring products using nfc tag technology, I tried to find a practical method that can be applied to modern ornaments produced in the workshop. As a result, two realistic alternatives were drawn: the investment method, which is free to converge, but has limited technical utilization, and an assembly method that requires high convergence from the design planning stage. After then, to know investment methods, have been produced that may have problems with real applications. I made a real sample, not a concept, to explain the technical factors and precautions necessary for applying nfc technology.

As the storm water runoff characteristics in urban areas have changed owing to urbanization, centralized facilities to reduce the urban flood runoff had been implemented. On the other hand, because they have their limitations, LID (Low Impact Development) of the distributed facilities for storm water runoff reduction is being actively planned and applied. The purpose of this study was to analyze the runoff characteristics for the spatial distribution of typical LID element techniques. This study set a study basin consisting of the five subbasins with the same basin and drainage systems, and analyzed the flood runoff characteristics from the two scenarios, one is for the locations and the other is for the number of green roofs (GR) and permeable pavement (PP), respectively, selected as typical LID element techniques. The SWMM implementation results showed that GR reduces 11.07% of the total and 3.42% of the peak amounts of storm water runoff, and PP leads to 18.09% of the total and 17.94% of the peak discharge reduction for a subbasin. Such a reduction rate is constant regardless of the LID locations, and increases linearly with the number of LID applications. The different runoff reduction rates between the GR and PP applications appear to be due to the effects of the different hydraulic conductivities in the control parameters for each LID.

This study aims to provide intellectual access to TV content using faceted classification. In order to describe the content of news and current affairs programs, a faceted approach was explored. Based on the Ranganathan's PMEST formula, the basic facets - 'who', 'what', 'how', 'where', 'when' - and their sub-facets were created, specifically for describing the news genre. Additionally, the formal structure and the contextual features of the news genre were mainly considered for creating sub-facets. These created facets were applied to a news genre program. The result shows that these suggested facets are useful for representing well the contextual components of the news genre. The application of faceted classification is expected to improve the identification of the specific TV content.

The boundary element method was newly implemented into an optical lithography simulator so that it could evaluate rigorously the topological effects of 2dimensional phase-shifting masks. Both transparent and periodic boundary conditions were applied for the method, and the continuity conditions were used for treating interface nodes. The accuracy of the module developed for simulating aerial images was verified by comparison with analytic solutions and published results. In addition, it was found that our simulator would be more efficient than the conventional method based on the rigorous coupled wave analysis in views of the convergence and the calculation speed. Finally, the optimal design of two phase-shifting masks was performed.

Full-scale test facility is a huge system which is integrated by many subsystems. There are several critical elements in test facility system. Those elements may cause undesirably test article failure during testing. Therefore, test facility monitoring system which indicates the operating status of the critical elements is required for performing full-scale structural test. Selection of critical element and design of this monitoring system are explained in detail in this paper. The monitoring system developed are being applied to T-50 full-scale static test, will be expended for full-scale fatigue test in the near future.

The convergence of education and game came from efforts to compensate for the boredom of learning. As the digital technology has been developed, this new integrated field accrued to the birth of the Educational Serious Game. It has been noted on both side of industry and academic research. Despite all natural concerns, studies of the educational Serious Game tend to show the partial directivity on the learning aspects rather than the nature of the Educational Serious Game. Therefore in this study the combination aspects of fun and learning in the Educational Serious Game through various case studies is to analyse.

Structural effects of several geometric parameters such as shroud thickness, edge roundness and fillet radius of turbopump turbine blade were investigated throughout transient finite element analyses. Usually shroud is inserted to increase aerodynamic efficiency, but blocks deformation of blades. Therefore it can increase stress level in a structural point of view. Likewise, edge roundness and fillet between blades are also parameters where aerodynamics and structural mechanics should compromise. In this study, overall stress levels according to the geometric parameters were thoroughly investigated and the results could be utilized to determine optimal geometries.

To enhance competitiveness of game industry and added value, it needs scientific research and bases that suggest satisfaction standard which quantitatively evaluates satisfaction to develop games which have high satisfaction for demanders. Specially, scoring of satisfaction factors and estimation of population distribution are important task. This allows which a game have high or low satisfaction compared to other games. Also we predict improvable factors and technical aspects to promote satisfaction. For it, in this paper we discuss ways to normalization of score distribution for satisfaction factors and estimate its density function using parametric density estimation by simulation.
