This study was performed on purpose to consider the charade function of props in directing animation. The prop is gradually expanded its role and scope in modern animation. Its scope covers dramatic factors, creating and changing characters, the means of psychological description or emotional expression, mise-en-scene, montage, creating products etc. Like this, the prop has an important function emotionally or indispensably in human life. Thus, the prop should be a subject that can speak to audiences or viewers, not worthless and silent subject. Hence, the prop should be recognized as a charade having productional function. Nevertheless, the prop has been unnoticed up to now. The function of props should be valued hereafter. The prop itself is meaningless, but it always speaks to audiences on the screen.

In the context of the 4th Industrial Revolution, IoT, Big Data, and VR are rapidly emerging as core sectors of future industries. In particular, the VR has been under the limelight as a new media content appealing to new generation. And the VR user is not merely a 'spectator', but the 'actor'. In other words, the newness of VR is not in the 'more likely representation of the virtual reality', but in the 'making it act more virtual (more technically, 'interactive')' in the virtual world. In this paper, we examine the VR cinema in terms of film composition unit, montage, cinematic space, mise-en-$sc{\grave{e}}ne$ and perspective. The VR cinema, which is in the early stage of evolution, is basically based on $360^{\circ}$ image that strengthens the autonomy of the audience's point of view, but other factors like haptic or sonic immersion are becoming increasingly important. In addition, the VR cinema will be combined with AR, MR, SR, and Interactive technologies, and will expand its horizon as it is produced in various forms. Therefore, it is expected that more detailed viewpoint will be applied in the subsequent study on VR cinema.

Recently, the computer vision has been applied to many automation fields. Especially, this paper presents a maritime traffic detection system using computer vision since the high level information can be obtained using obtained area information. The high level informations are obtained such as speed, queueing length, queueing time, ship size, and ship kind. To get ship speed, the two detection lines are set on the predetermined screen position. The speed is obtained the passing time and the predetermined distance between the first and second detection line on the screen. Also, queueing length and time are gotten using screen position of ship. Furthermore, the size and kind of ship are calculated using the ship database and camera calibration data. This developed system contributes to reduce the traffic accidents on the coast. Futhermore, the more information can be extracted using obtained area information.

This paper describes the method that voice traffic is served efficiently in BISDN. Voice is divided into talkspurt and silent period, and it is possible to transmit olny talksurt by the speech activity detection. This paper described the voice traffic control algorithm in the ATM network where cell discarding method is applied to the embedded ADPCM voice data. For traffic control, the cell discarding was used over low priority cells when it overflows the queue threshold. To estimate the efficiency of traffic control algorithm, the computer simuation was performed with cell loss probability, queue length and mean delay as performance parameters. The embedded ADPCM voice coding and cell disscarding resulted in improving the voice cell traffic efficiency and the dynamic control over network congestion.

The first zoea of Liomera bella belonging to the subfamily Liomerinae is described and illustrated for the first time. Its morphological characteristics are compared with those of other known species of the Xanthidae The general morphology of it corresponds well with zoeas of the Xanthidae. Based on the zoeal morphology, the zoea of L. bella shows a greatest affinity with those of Xontho incisus and Pseudomedaeus agassizii by having the exopod of antenna with two setae, the terminal segment of the endopod of the second maxilliped with six setae, and the fork of telson with one stout and one smaller lateral spines.

In this study, in Tongyeong area the distribution of marine products that were produced and treated through fishing and cultivating industry and the trend of main fisheries were investigated for fisheries distribution system and fisheries official circles, and then a structural model of fisheries distribution system for direct transaction was suggested under internet environment, which is an important scheme offering a necessary information rapidly and practically to both producers and consumers. Database system was structured according to distributed process. An op-elative scheme were suggested for sewers of local area information center, complementing functions to exceed each server's ability.

In this paper, we propose a fixed-complexity sphere encoder (FSE) for multi-user MIMO (MU-MIMO) systems. The Proposed FSE accomplishes a scalable tradeoff between performance and complexity. Also, because it has a parallel tree-search structure, the proposed encoder can be easily pipelined, leading to a tremendous reduction in the precoding latency. The complexity of the proposed encoder is also analyzed, and we propose two techniques that reduce it. Simulation and analytical results demonstrate that in a $4\times4$ MU-MIMO system, the complexity of the proposed FSE is 16% that of the conventional QRD-M encoder (QRDM-E). Also, the encoding throughput of the proposed endoder is 7.5 times that of the QRDM-E with tolerable degradation in the BER performance, while achieving the optimum diversity order.

In order to improve the sensitivity of the wafer type heat flux sensor, some heat flux sensors were manufactured and examined by using thermoelectric semiconductor material (bismuth telluride) whose Seebck coefficient is much larger than those of metallic thermocouple materials. Because the thermoelectric element cannot be bended or welded, a peculiar sensor structure and manufacturing process were designed. As a result, it is revealed that the characteristic sensitivity of the manufactured sensor is about 10 times larger than that of marketed sensor even though there are some troubles in stiffness for reciprocal use. If we make this kind of sensors smaller and thinner, it will be a useful method to measure the local heat flux from the surface of complex configuration.

A new fungivle material named Epoxy-Granite composite is applied to the column structure of drilling center in order to investigate the advanced dynamic charateristics comparing with a conventional cast iron material. The dimensions of new column structure are adjusted to keep the same stiffness (EI value) and the manufacturing conditions are formulated based on the preceeding research experience about the development of Epoxy-Granite structural material. The two kinds of experiments are set up, one of which is for the measurement of natural mode and frequency using experimental modal analysis, and the other one is for the measurement of vibration amplitude during idling operation of a machine tool. The comparison of maximum accelerance values at each natural frequency of bending mode shows a Epoxy-Granite column have larger modal damping ratios(over 2times) than a cast iron column. The vibration amplitude of Epoxy-Granite column measrued on the bed, motor base, and top of column are also much smaller (up to 12%) than the case of cast iron column. It is therefore confirmed that a Epoxy-Granite material exhibits a good anti- vibrational propderty even if it is used under the actual operational environments of machine tool as a practical structural element.

In this paper, a new closed form expression for the average symbol error rate(SER) of generalized selection combining(SC), whereby the two(three) signals with the two(three) largest amplitudes are combined from the original diversity branches in the channel, for MPSK signals in a frequency-nonselective slowly m-distributed Nakagami fading channel is derived. In order to analyze the error performance for a generalized SC, the Order-Statistics is applied. To derive the SER of MPSK signals with SC, the new expression of pdf is introduced and many other mathematical methods are used. Comparing the derived SER with that of MRC, we find adequate diversity branch number from total Lth-order diversity branches.
