본 논문에서는 키 영상과 암호화 영상의 암호화 수준을 동등하게 하기 위해서 분할 영상을 제작하여 결합변환 상관기의 주파수 영역을 이용한 광 암호화 시스템을 제안하였다. 제안한 암호화 과정은 원 영상의 반조 영상을 만들고 이를 시각 암호화를 이용하여 두 개로 나누어 분할 영상으로 만든다 두 개의 분할 영상 각각 위상변조 한 후 위상변조된 무작위 영상을 곱하고, 이들을 각각 푸리에 변환하여 두 개의 최종 암호화 영상을 얻는다. 그 두 암호화 영상 중에 하나를 복호화 키로 사용하여 진위 여부를 판별하게 된다. 제안한 방법에 의해 제작된 암호화 영상은 1차로 시각 암호화를 이용하여 암호화시키고 2차로 위상변조된 무작위 영상을 곱해서 암호화하므로 복제와 위조를 통한 위상정보의 유출에도 원 영상의 복원을 막을 수 있으며, 원 영상 재생에 결합변환 상관기의 주파수 영역을 이용하기 때문에 시스템 구성이 간단하며 두 암호화 영상 중에 특정한 영상을 복호화 키로 쓰지 않아도 된다. 본 논문에서는 컴퓨터 모의 실험을 통해 제안한 방법의 타당성을 확인하였으며 잡음에 대한 영향을 분석하였다.

$Chos{\check{o}}n$ Dynasty was governed by the words of king, however, if they were not announced by the form of public document, they were useless. Therefore, the form of public document was the symbol of governing activity, and it was very important to manage the public record in operating the nation affairs. However, the point we should consider is that $Chos{\check{o}}n$ Dynasty, in the case of managing the public record, edited 'the original' instead of preserving them. And so, the preservation of the public record was deeply related to the editing of history. In Late Korea dynasty, the management of the public record got into utter confusion and so many troubles were occurred. In order to resolve these problems, the movements which innovated the public record managements system was gradually extended. This movements were continued in $Chos{\check{o}}n$ Dynasty. Finally, through the several modification procedures, the rules of public record management were legislated by 'Kyong Kuk Dae Jeon'(經國大典). Especially, by laws of 'Kyong Kuk Dae Jeon', not only the daily records of Secretary Department(承政院) but also the important documents which was related to the government branch should be booked in the last decade of the year and the number of the books had to be reported to the king. This rule made certification of the fact that the king was the last confirmer of the public record management. In addition, through the procedure of printing the record of the national affairs, and the diplomatic once in three years, and then preserving that public record in the National Department(議政府), other departments responsible and the archives, the National Department practically took part in the public record management. The management system was also changed in order that the public record was virtually used and consulted before taking the procedure of immortal preservation. All public documents were classified by the definite rule and filed in a same volume. After classifying and filing, certainly, for making convenience of reference and application of public record, records were indicated by the paper card. It may be that, after the step of reference, application and indicating, the public documents were gradually transferred to the next step. In these procedures, Early $Chos{\check{o}}n$ public documents system was confirmed.

Recently, the certification procedure for exhaust emission regulation of LDV has tested with the NEDC mode in the laboratory. But the on-road exhaust emissions exceed the standard emission limits. Therefore, it is important to analyze the real-driving emissions (RDE) with a portable emissions measurement system (PEMS). In present study, the on-road emissions were measured with a PEMS and evaluated by moving averaging window (MAW) method. Also, it was compared with the $CO_2$ and $NO_x$ emissions for real-driving and test modes from euro-6 light-duty vehicles equipped with SCR and LNT systems. In results, on-road $NO_x$ emission has been 2.3-10.0 times higher than the standard $NO_x$ emission limit on NEDC mode. The reason was that the test modes did not reflect traffic and various real-driving patterns sufficiently.

Conventionally, to measure derailment coefficient of a railway wheel, strain gauges for lateral force measurement are attached to both side of the wheel. But narrow gap between railway wheel and traction motor makes it difficult to attache the strain gauges at the inner side of wheel. In this study, to overcome the hard accessibility to the strain gauge points by narrow gap, a new Wheatstone bridge connection method is presented by attaching all the strain gauges at the outer side of wheel with a new bridge connection. We evaluate the running safety of railway vehicles in accordance with railway safety regulations. The experimental results obtained shows higher sensitivity than conventional methods and the derailment coefficient measurement procedure becomes simpler.

The helmet is an imperative personal protective equipment. This protective device must be able to guard the human head against potential risks. Helmets are classified according into the purpose of use; therefore, the required performance and specifications depend on the type of products. Military helmets are intended to protect the wearer's head from bullets and shrapnel. Generally, lightweight super fibers and fiber reinforced composite materials are used as helmet shell materials, and NIJ STD of U.S. Department of Justice is most widely used as international standard related to bulletproof helmets. Safety helmets are widely used for industrial application and sports leisure. In general, the performance of shock absorption must be ensured, and various lining systems are applied in material, design, and combination methods. Evaluation standards have also been classified and strictly controlled for each purpose; therefore, it is difficult to certify with the existing standards such as the recently developed convergence helmets. However, it is possible to launch the product through a separate national integrated certification procedure.
