  • A variety of sensory elements are used in video advertisements promoting products. Video advertising using visual and auditory elements is a representative means of marketing. The advertising video that promotes the product by using such a sensory element is imprinted on viewers by continuously or repeatedly exposing visual elements such as a logo or a specific image or phrase. Such visual images are used as an effective way to symbolize brand image effectively. If the visual elements were symbolized in the advertising images of most car brands, Kia's K5's advertising images symbolized auditory elements, or sounds, to produce K5's unique advertising images. In this paper, we compared Kia's K5 advertisement image symbolizing auditory elements with other brands' advertisement image of other companies, and studied the techniques and effects used in advertisement image production.

  • Works engraving enlightenment and ethnic identity by giving meaning and lesson to past events and great people against the past can be one of the good ideal art film contents. The animation reproduces the existing cultural archetypes, situation and history, when the 'Book of Kells' was produced, and the myths of the Kelts tribes. This thesis analyzes the history the kelts, traditional patterns and formative symbolism shown in , and studies the cultural preservation method unique to animation contents. In conclusion, the movie not only suggests a methodology that animation content is an effective way to preserve the culture and history of the native people, but also pursues the eternal, enlightening and teaching people for history.

  • In this paper, a formulation for obliquely incident electromagnetic wave has been presented for an analysis of highpower electromagnetic pulse penetration into multilayered dispersive media. Based on generalized models of measured dielectric constants and propagation channels reflecting the Earth's general features, the propagation phenomenon of the obliquely incident early-time(E1) high altitude electromagnetic pulse(HEMP) is analyzed. In addition, the polarization and critical angle are also considered. It is found that the total reflection occurs at an incident angle of about 38 degrees at the soil-rock interface, and that the parallel-polarized E1 HEMP penetrates better than the perpendicular-polarized one. The peak level of the penetrating electric field is found to be 5.6 kV/m at normal incidence, regardless of the type of polarization, and E1 HEMP is greatly reduced near the critical angle. Moreover, the penetrating E1 HEMP is analyzed as a variation of moisture content and depth of materials, resulting E1 HEMP could be useful in determining the levels of shielding required for buried facilities.

  • In this paper, we present a vision algorithm and method for input image improvement and preprocessing of dented and raised characters on the sidewall of tires. we define optical condition between reflect coefficient and reflectance by the physical vector calculate. On the contrary this work will recognize the engraved characters using the computer vision technique. Tire input images have all most same grey levels between the characters and backgrounds. The reflectance is little from a tire surface. therefore, it's very difficult segment the characters from the background. Moreover, one side of the character string is raised and the other is dented. So, the captured images are varied with the angle of camera and illumination. For optimum Input images, the angle between camera and illumination was found out to be with in 90$^{\circ}$. In addition, We used complex filtering with low-pass and high-pass band filters to improve input images, for clear input images. Finally we define equation reflect coefficient and reflectance. By doing this, we obtained good images of tires for pattern recognition.

  • Accurate cloud discrimination in satellite images strongly affects accuracy of remotely sensed parameter produced using it. Especially, cloud contaminated pixel over ocean is one of the major error factors such as Sea Surface Temperature (SST), ocean color, and chlorophyll-a retrievals,so accurate cloud detection is essential process and it can lead to understand ocean circulation. However, static threshold method using real-time algorithm such as Moderate Resolution Imaging Spectroradiometer (MODIS), Advanced Himawari Imager (AHI) can't fully explained reflectance variability over ocean as a function of relative positions between the sun - sea surface - satellite. In this paper, we assembled a reflectance spectral library as a function of Solar Zenith Angle (SZA) and Viewing Zenith Angle (VZA) from ocean surface reflectance with clear sky condition of Advanced Himawari Imager (AHI) identified by NOAA's cloud products and spectral library is used for applying the Dynamic Time Warping (DTW) to detect cloud pixels. We compared qualitatively between AHI cloud property and our results and it showed that AHI cloud property had general tendency toward overestimation and wrongly detected clear as unknown at high SZA. We validated by visual inspection with coincident imagery and it is generally appropriate.

  • The methods of providing available bandwidth adaptively using feedback to maximize the utilization of network as well as the quality of service have been the focus of recent research activities for ATM(Asynchronous Transfer Mode). This study has been extended from the point-to-point connection to a point-to-multipoint environment as the number of applications requiring multicast service increases. It is known that the effectiveness of feedback based congestion control scheme diminishes as propagation delay increases. Especially for a multicast connection consisting of various paths and destinations with different performance and congestion status, the problem of unfairness due to different propagation delays may occur. The degree of such unfairness may change depending on various aspects of congestion control schemes. These has been, however, relatively little study on these problems. In this paper, we present how various aspects of control schemes-length of the interval between feedback generations, point of time to coalesce feedback cells from child paths, decreasing factor of source rate in case of congestion-affect the degree of unfairness. Simulation results show that degree of unfairness changes according to when the feedback coalescing happens. Expecially it is shown that the effect of feedback coalescing time to the degree of unfairness is more significant for the smaller feedback interval. It is also found that as the source rate decreasing factor becomes larger the average ACR(Allowed Cell Rate) at the source gets lower and the degree of unfairness grow larger.

  • This study conducted scientific analysis and preservation treatment for the local 7 relics (depurator bottle, eagle patten button, rank insignia, mess tin, M1 Grand-gun cleaning tool kit, Carbine bullet, cartridge) of the fallen of Korean War excavated through the MND Agency for KIA Recovery & Identification that are possessed in the exhibition hall of the Ground Operations Command. FT-IR analysis results show that remainder of depurator bottle is assumed to play a role of water and food purifier during the war for its spectrum similar to Trisodium phosphate, and inscription carved on the cartridge that is hard to observe with naked eyes was also confirmed through 3D digital shooting method. This study also established directivity of preservation treatment of relics for stable treatment by carrying out a survey of conditions based on the microscope and visual observation. The result is expected to be used as basic data for establishment of future directivity of preservation treatment for a variety of war relics.
