The influence of digital media according to environmental change of multi-media came to have significance more than what we imagine. In accordance with high resolution of HDTV in digital media era, the cautious awareness is required for skin color by the immediate color such as replica of TV color, lighting and clothing. As for the broadcasting makeup expression technique caused by a change in broadcasting environment in the digital media era, the first, There is necessity for natural makeup technique, and for expressing the whole makeup evenly and very delicately. The makeup work gets much more delicate. For the delicate expression, more time is being required than the existing makeup time. Second, Lots of time and manpower are required for elaborate real-object processing on all the production fields such as background set, stage properties, and makeup. Third, Realistic expression is available on the screen. Importance of basic makeup is highlighted. Thus, even the skin care shop came to be prevalent. Development in only HD cosmetics is needed for foundation with fine particle in new material and with diverse colors hereafter. The video-media field is a method that is ignored a sense of distance through vehicles such as camera, picture tube, and several kinds of broadcasting machinery and equipment and that is delivered vividly to viewers through screen, unlike the stage makeup, thereby being needed the makeup technology proper for HDTV according to the changing broadcasting environment and media. The video machinery and equipment are proceeding with being gradually high-tech and precise. Thus, an expert in makeup needs to know common sense on the video machinery and equipment before makeup, and needs to make an effort according to it. And, a follow-up research can be said to be necessary on the advance in makeup method and on more diverse dedicated cosmetics along with a research on color tone proper for HDTV.

The purpose of this study is to analyze how the aesthetic characteristics of Brecht's V-Effekt is visually expressed of the costume in the Traditional Play of Korea, China and Japan. The method and the contents of the study were to refer to the antecedent studies and the related documents to peruse the characteristics of the traditional plays of the East and West, the origin and the concept of Brecht's Verfremdung and considered the relation of Brecht's V-Effekt and the Oriental plays, and then the researcher derived the aesthetic properties of Brecht's V-Effekt. This study analyzed how those qualities of the aesthetic characteristics on the V-Effekt are manifested on the stage costumes of Korean mask, Beijing opera and Kabuki. The aesthetic qualities of Brecht's V-Effekt are classified into symbolism, grotesque disposition, character of sing and dance, comicality. The symbolism in the traditional play costumes of the three nations is shown in the colors of the masks in Korean and the tone of the colors on the costumes and the make-up in Beijing opera and Kabuki. While the properties of bizarrerie and deformation coexist in masque and Beijing opera costumes in terms of grotesque disposition, Kabuki strongly displays bizarre grotesquerie. The character of sing and dance is visually expressed through the transformation of sleeves on the three nation's traditional play costumes; Masque on the Hansam and Chengsam, Beijing opera on the Water sleeves and Kabuki on Hurisode. The comic aspection is expressed in a humorous and comical way through the distortion and transformation of forms in Masque and Beijing opera but it cannot be seen in Kabuki costume. The study as above will form the aesthetic properties of the Oriental traditional play costumes and also it will contribute to establishing the identity of Korean mask costumes.

The feasibility of counting number of small vessels and position in Korean waters using the panchromatic imageries derived from the IRS-1C was tested. The parameters for interpretation of satellite's imageries of small vessels were location(position), size, shape, shadow, tone, texture and pattern, height and depth, situation and association with other vessels. The position of small vessels in the sea without GCP(ground control point) was considered to be inclusive in the satellite imagery with 35 km semi-diameter, denoting rough geographical position of the vessel. The size of vessel was measured by length from stem to stern of the vessel, distinguished by following wave on the surface water. Offshore fishing vessels were separated from merchant ships by their length smaller than 100 m. The shape of vessels on panchromatic imagery of IRS-1C appeared just streamline. In case of clouds which were similar to the shape of small vessels, we were able to distinguish between vessel and cloud by shadow of cloud in the water surface. The tone of sea surface was dark black while small vessel appeared bright white. Small vessel was distinguished from the rough texture of the sea surface and the regular pattern of the waves with white capes when weather was not so good. The situation of the fishing activity was estimated by information of fishing method related to the fishing boat such as the pair trawl in the Yellow Sea.

We studied the effects of vibration stimulation method on upper limbs spasticity in patients with brain lesion. 21 patients with spasticity of the upper limbs selected and divided randomly 3 groups. And then vibratory stimulation was applied to the triceps brachii muscle in group I(n=7), to biceps brachii muscle in group II (n=7), and to both muscles in group III (n=7). Using Neuro-EMG_Micro to investigate the changes in spinal neuronal excitability, F-waves were measured at before and directly after stimulation, and 10 minutes later and 20 minutes later after stimulation especially. MAS(Modified Ashworth Scale) test for muscle tone and MFT(Manual Function Test) for the upper extremity motor function were performed before stimulation and 20 minutes later after stimulation for the purpose of clinical evaluation. In our study, MAS was significant decreased in all groups, F wave and F/M ratio parameters were decreased in all groups and more decreased specially in group III. MFT was increased in group II and III, and more increased specially in group III. Vibration stimulation reduced the neuronal excitability of spinal cord and also muscle tone, and improved the motor function of the upper extremity. These results suggested that vibration stimulation giving to both muscles(triceps and biceps brachii muscle) at the same time was more efficiency in reducing the neuronal excitability of spinal cord and improving the motor function of the upper limbs.

With the development of display engineering and technology, the screen and sound quality of information devices such as TVs are improving. The screen used LEDs via LCD and PDP and a large flat panel in the early CRT to create super-high resolution. The sound is improved by directly vibrating a thin and simple panel, such as an OLED. In our previous study, the exciter speaker was attached to the rear of the OLED panel to be used as the diaphragm of the speaker, and the sound quality was as good as that of the TV using the existing dynamic speaker. This method supplied the viewer with the direct sound coming from the panel, delivering clear sound, and the sound and image came from the same location, thus giving the viewer high immersion and maximizing the effect of information transfer. OLED exciter speakers, however, have a special directivity, which tends to slightly attenuate the tone at the very center of the screen. This study improves the sound quality by improving the structure of the exciter speaker and the radiated sound of the flat panel display. A 2-in-1 Exciter is made into a single core to improve the speaker's radiation pattern.

Recently, Organic Light Emitting Diode (OLED) that is broadly applied as next generation display has various advantages. However, OLED display causes unbalanced color tone due to the difference of luminance efficiency among luminous elements. In this paper, we propose adaptive color shifter (ACS) to resolve the RGB channel unbalance and to have wide color range of a relatively weak channel using the image processing method. proposed ACS system was simulated using a variety of image. Also, we numerically analyzed using hue histogram, CIE-1931 xyz color space.

Spatial control of sound is essential to deliver better sound to the listener's position in space. As it can be experienced in many listening environments, the quality of sound can not be manifested over every position in a hall. This motivates us to control sound in a region we select. The primary focus of the developed method has to do with the brightness and contrast of acoustic image in space. In particular, the acoustic brightness control seeks a way to increase loudness of sound over a chosen area, and the contrast control aims to enhance loudness difference between two neighboring regions. This enables us to make two different kinds of zone - the zone of quiet and the zone of loud sound - at the same time. The other perspective of this study is on the direction of sound. It is shown that we can control the direction of perceived sound source by focusing acoustic energy in wavenumber domain. To begin with, the proposed approaches are formulated for pure-tone case. Then the control methods are extended to a more general case, where the excitation signal has broadband spectrum. In order to control the broadband signal in time domain, an inverse filter design problem is defined and solved in frequency domain. Numerical and experimental results obtained in various conditions certainly validate that the acoustic brightness, acoustic contrast, direction of wave front can be manipulated for some finite region in space and time.
