  • 본고에서는 국제 규격에 있어 국제기구인 CISPR와 국가규격으로는 미국, 서독, 영국, 캐나다, 일본 그리고 특수한 규격으로 MIL-STD와 TEMPEST 규격에 관하여 살펴보고자 한다. EMI에 대한 국제규격은 초기에는 국제 무선 항행, 통신 및 서비스의 보호라는 차원에서 출발하여 최근 정보기기의 범람에 의한 제어 시스템에 의해 가능성에 대한 안전보장과, 본고에서는 언급되지 않으나 때로는 인체의 위해(Hazard)를 방지하기 위한 경우, 또 특별한 분야로써 중요 정보의 누출 보호(TEMPEST)기술 등 다양한 분야로 확대되고 있다.

  • Due to the rapid development of open source based Cloud management platforms such as OpenStack, many and various individuals and institutions are trying to construct Cloud computing systems based on open source software projects. It is essential, for those who install, administrate or operate a Cloud, to validate the integrity of the constructed Cloud system. This paper, therefore, proposes the design of a testing tool for validating the integrity of a constructed OpenStack-based Cloud system. Especially, the proposed testing tool utilizes the Tempest project which is an open source project that consists of OpenStack test cases. The proposed testing tool is expected to help developing Cloud technology and Cloud users.

A Study on Stage Costume of Shakespeare's "The Tempest" - Focusing on the Color Symbolism - (셰익스피어의 "The Tempest" 무대의상(舞臺衣裳) 연구(硏究) - 색채(色彩) 상징성(象徵性)을 중심(中心)으로 -)

  • The purpose of this study was illumination of the stage costume by applying the study of a subject of human expression, which establishes identity of dramatic characters. This study was conducted by referring a variety of theses, an extensive national and international literature. The color symbolism that is depicted in Shakespeare‘s work manifests the transition period of old days, which was influenced by the Renaissance and the Religious Reformation. And color preferences and the meanings I attach to them in his play, definitely reveal the Middle Ages Christian way of thinking which was obsessively dominated their mind. I also determine that the color preferences and use in Elizabeth Era also distinctively separate the social status, which were also influenced by its social conditions. Besides this, colors that were depicted in Shakespeare's work also shown many similarities from Italian Commedia dell‘arte, which were in vogue all over the Europe. Customary color symbolisms which from natural color experiences were also applied in "The Tempest". "The Tempest" was presented on the first day of November in 1611 for the first time. Following this, many plays and films have been produced in foreign countries and Korea. With an analysis of "The Tempest", costume designs for Miranda and Ferdinanad were illustrated at the end. The costumes for Miranda and Ferdinand were mainly considered to express pure love and vigorous youth of two lovers, symbolizing the image of the theme love, forgiveness, and reconciliation.

  • We proposed the Power-line EMI filter for vehicle-shelter which have attenuation performance of 100 dB from 10kHz to 1 GHz. The inductor and capacitor for EMI filter design was charactenzed using circuit simulator and then, we experimentally verified 100 dB attenuation for the conducted emission noise through power line. This results will be used for the application systems of protection weapons against EMI attacks as well as vehicle-shelter.

  • Generally, the compromising electromagnetic emanations are generated from LCD(Liquid Crystal Display) monitor which is typical output component of computer. Because display information transmitted to LCD monitor is included in these emanations, there are risks about information leakage of monitor by eavesdropping of leaked signal. So, analysis about possibility of information leakage is necessary because electromagnetic security through the electromagnetic emanations is being at issue. In this paper, the possibility of display information leakage are demonstrated by analyzing the electromagnetic emanations from desktop and laptop monitors. The characteristics of leaked signal from LCD monitor is verified by analyzing display mechanism and the electromagnetic emanations are measured in the long distance by eavesdropping experiment. Also, threat of information leakage is confirmed by recovering display information with several signal processing technique and comprising with target display.

  • Large sized marine structures are used under corrosion environment of seawater and applied by severe service loading such as an ocean current, a billow and a tempest. Marine structures are usually constructed by lots of thick wall steel pipes joining welded joints. The thickness of such as steel pipes is usually more than 40mm. The such as steels are called "Thermo-Mechanical Control Process steel (TMCP steel)" strengthened by a heat treatment in process of steel manufactures. The failure, especially crack initiation, of marine structures was starting at weld joints under service condition. Then they should be designed by basis of the fatigue strength under seawater corrosion environment of weld joints. To clarity the fatigue crack initiation behavior is important more than to clarify the crack propagation behavior on the strength design of marine structures, because it is very difficult to find out the crack initiation and propagation phenomena and then even if it will be able to find out, it is considered that the refit of the damaged parts of welded joints have a technical difficulty under the sea. Therefore, it is most important to clarify the corrosion fatigue crack initiation behavior under the seawater condition. But, there is one big difficulty to make a test for thick plate specimen, for example thicker than 40mm. Because, it is need large capacity loading apparatus to test such as thick plate specimen. In this research, the new configuration specimen for fatigue crack initiation tests was proposed. Using this new specimen, it is easy to carry out the fatigue clack initiation tests with relatively low cyclic loading and to observe a fatigue crack initiation behavior.
