As Damyang has preserved both beautiful natural environment and tradition very well, it needs colors which can coexist with Damyang while preserving it as it is rather than colorful and refined colors. However, the present Damyang deteriorates the quality of beautiful natural scenes by chaotic uses of colors. Therefore, colors which can represent symbolism based on the present colors of Damyang should be used so that everyone can be pleased with them. Finally, the basic colors decided were classified into main, supplement and highlight colors in consideration of characteristics of each scene and they were effectively arranged based on the colors decided. If such colors and color schemes are properly applied according to characteristics of scenes, ecological, historical, cultural and traditional scenes of Damyang can be preserved consistently. Academic literature uses the abstract to succinctly communicate complex research. An abstract may act as a stand-alone entity instead of a full paper. As such, an abstract is used by many organizations as the basis for selecting research that is proposed for presentation in the form of a poster, platform/oral presentation or workshop presentation at an academic conference. Most literature database search engines index only abstracts rather than providing the entire text of the paper. Full texts of scientific papers must often be purchased because of copyright and/or publisher fees and therefore the abstract is a significant selling point for the reprint or electronic version of the full-text. Abstracts are protected under copyright law just as any other form of written speech is protected. However, publishers of scientific articles invariably make abstracts publicly available, even when the article itself is protected by a toll barrier. For example, articles in the biomedical literature are available publicly from medline which is accessible through design. It is a common misconception that the abstracts in medline provide sufficient information for medical practitioners, students, scholars and patients. The abstract can convey the main results and conclusions of a scientific article but the full text article must be consulted for details of the methodology.

The electro-optical characteristics of the Liquid Crystal on Silicon (hereinafter "LCOS") micro-display on vertically alignment (VA) mode were studied with 3-dimensional LC code. 5 different cell gaps, such as 1.4 ${\mu}m$, 1.8 ${\mu}m$, 2.1 ${\mu}m$, 2.4 ${\mu}m$ and 2.8 ${\mu}m$, were selected. The reflectance-voltage (R-V) characteristics, distribution of reflected light, reflectance, optical fill factor and contrast ratio were calculated and investigated depending on various cell gaps. Due to the surface anchoring effect, higher cell gap showed higher reflectance. However, considering the optical fill factor and contrast ratio, middle-height 2.1 ${\mu}m$ showed the best electro-optical characteristic. 0.7 inch Full-HD LCOS panels having same geometry and material property were fabricated. The reflected light intensity and contrast ratio were measured and the measured results were well-matched to the calculated results.

This paper proposes road safety facilities applying Hot-dip zinc-aluminum-magnesium alloy-coated steel sheets and coils to reduce the loss of function caused by the corrosion of steel in the service state. Vehicle crash simulations and full-scale crash tests were carried out to provide reliable information on evaluating the crash performance with the products of road safety facilities built with hot-dip zinc-aluminum-magnesium alloy-coated steel. From the results of the simulations and full-scale crash tests, the impact behaviors evaluated by the three-dimensional crash simulations considering the strain-rate dependency in a constitutive model were similar to those obtained from the full-scale crash test results. The full-scale crash test results met the crashworthiness evaluation criteria; hence, the proposed bridge barrier in this paper is ready for field applications.

The advertisement system on TV is categorized into full duplex TV and Internet Protocol Television (IPTV). For the full duplex TV or the IPTV, channel providers need a number of advertisements and pay enormous expenses for them. Therefore, this study proposes how to reduce unnecessary expenses based on users' preferences. The advertisement system based on users' preferences is designed to decrease unnecessary advertisements with less expense. To identify preferences in usual advertisements and animation advertisements is to reduce expenses due to the necessity of a number of advertisements. The proposed system was designed to provide full duplex advertisements for profits of advertisement industry and considered users' disposition based on preferences of broadcasting advertisements, through which users can have advertisement desired and providers can expect less advertisement expenses and more profits.

In applying LCD to TV application, one of the most significant factors to be improved is image sticking on the moving picture. LCD is different from CRT in the sense that it's continuous passive device, which holds images in entire frame period, while impulse type device generate image in very short time. To reduce image sticking problem related to hold type display mode, we made an experiment to drive TN-LCD like CRT. We made articulate images by fast refreshing images, and we realized the ratio of refresh time by counting between on time and off time for video signal input during 1 frame (16.7ms). Conventional driving signal cannot follow fast on-off speed, so we evaluated new signal generator using SDI (Serial Data Interface) mode signal generator. We realized articulate image generation similar to CRT by high fast full HD (High Definition) signals and TN-LCD overdriving. As a result, reduced image sticking phenomenon was validated by naked eye and response time measurement.

In conventional cooperative communication data rate is 1/2 than non cooperative protocols. In this paper, we propose a full data rate DF (Decode and Forward) cooperative transmission scheme. Proposed scheme is based on time division multiplexing (TDM) channel access. When DF protocol has full data rate, it can not obtain diversity gain under the pairwise error probability (PEP) view point. If it increases time slot to obtain diversity gain, then data rate is reduced. The proposed algorithm uses orthogonal frequency and constellation rotation to obtain both full data rate and diversity order 2. Moreover, performance is analyzed according to distance and optimized components that affect the system performance by using computer simulation. The simulation results revealed that the cooperation can save the network power up to 7dB over direct transmission and 5dB over multi-hop transmission at BER of $10^{-2}$. Besides, it can improve date rate of system compared with the conventional DF protocol.

This paper investigates the capacity for the secondary user with the primary full duplex relay (FDR) network in spectrum sharing systems. For sharing the spectrum of the primary user, sharing scheme under the various primary network should be investigated. However, the conventional works only consider the point-to-point primary communication system. When the FDR node is used for the primary networks, both primary relay and destination suffer the interference from the secondary transmitter simultaneously. Thus, the strict interference constraint should be considered to share the spectrum of the primary user. Therefore, we investigate the capacity of the secondary user with the primary FDR network under the average and peak received-power constraints. In addition, we analyze the performance degradation by the selection of the worst interference channels to consider interference constraint in this system. Through the numerical results, the capacities of the primary and secondary users under the average received-power is superior to the that under the peak received-power constraint.

In this paper, a wide-input range CMOS multi-mode rectifier for wireless power transfer system is presented. The output voltage of multi-mode rectifier is sensed by comparator and switches are controlled based on it. The mode of multi-mode rectifier is automatically selected by the switches among full-wave rectifier, 1-stage voltage multiplier and 2-stage voltage multiplier. In full-wave rectifier mode, the rectified output DC voltage ranges from 9 V to 19 V for a input AC voltage from 10 V to 20 V. However, the input-range of the multi-mode rectifier is more improved than that of the conventional full-wave rectifier by 5V, so the rectified output DC voltage ranges from 7.5 V to 19 V for a input AC voltage from 5 V to 20 V. The power conversion efficiency of the multi-mode rectifier is 94 % in full-wave rectifier mode. The proposed multi-mode rectifier is fabricated in a $0.35{\mu}m$ CMOS process with an active area of $2500{\mu}m{\times}1750{\mu}m$.

This paper describes the new design technique of full wave rectifier (FWR) for precise measurement instrument and the chip implementation of this FWR circuit with measurement results. Conventional circuits have some problems of complex design and limited output range( $VDD/2{\sim}VLIIV1IT+$). Proposed FWR circuit was simply designed with two 2x1 MUXs, one high speed comparator, and one differential difference amplifier(DDA). One rail-to-rail differential difference amplifier(DDA) performs the DC level shifting to VSS and 2X amplification simultaneously, and enables the full range ($Vss{\sim}VDD$) operation. The proposed FWR circuits shows more than 50% reduction of chip area and power consumption compared to conventional one. Proposed circuit was implemented with 0.35um 1-poly 2-metal CMOS process. Core size is $150um{\times}450um$ and power dissipation is 840uW with 3.3V single supply.
