Companies, to establish a proper brand image of it, and to appeal to consumers effectively, mobilize advertisement and other publicity means through various communication media. In terms of access rates and degrees of interest of viewers among broadcast media, television is higher than other important media such as radio, newspaper, magazine, and DMB, etc. Since consumers get access to much commercials on television, television commercial activities of companies ultimately have effect on their brand images. Thus, this study, focusing on the screen image expression types among all the expression types of television commercials, examined what brand images consumers favor, and sought to know what characteristics in television commercials in Korea works as important factors in the formation of brand images.

Optical properties of aerosols associated with haze events over Seoul were examined using ground-based skyradiometer and satellite-borne CALIOP and MODIS measurements over the 2009~2010 period. It is shown that aerosol optical thickness (AOT), ${\AA}ngstr{\ddot{o}}m$ exponents (${\alpha}$), and fine-mode particles increase during the haze events. The CALIOP-measured vertical profiles of aerosol during the haze events revealed that most of aerosols are loaded within layers below 4 km altitude. A large portion of these events appear to be related to the long-range transport of aerosols from China; about 35% and 18% of the haze events observed over Seoul were traced back to northern China and southern China, respectively. Compared with optical properties for locally-induced haze events (25%), these long-range transported aerosols are found to have relatively higher AOTs.

The works of Vicenzo Scamozzi, the successor of Andrea Palladio are able to be comparable with Palladio's works in various ways. When comparing Villa Pisani of Scamozzi with Villa Rotonda of Palladio, their difference is evident. Both Villa Pisani and Rotonda are vacation villas located on low hills and have the magnificent beauty that overpowers their surrounding rural sceneries. However, Scamozzi doesn't show an obsession about Palladio's proportion. Palladio expressed the symbolic meaning of the villa as the center of surrounding rural scenery by having same porticos for all four facades of a square. On the contrary, Scamozzi built a portico only for one facade and constructed open loggias with serliana motif for other three facades. These loggias help lighting and ventilation of rooms located behind of loggias. Geometric innocence that is pursued by Palladio's villa can be understood as the archeological classism based on the nature interpretation from a classical viewpoint. On the contrary, Scamozzi pursued his own architectural characters that apply buildings to fit to their environment.

This paper studies how 2006 German World cup game gave World cup-aftermath to Korean people living in Korea. In order to study, the time exposure to soccer matches like Korea vs. Togo, Korea vs. Swiss, and Korea vs. France respectively was analyzed. Additionally, in order to evaluate media effect, respondents' demographics, and preference toward sports were controlled using a hierarchial regression method. Based on the results, exposure to radio was statistically significant to Koreans' indirect aftermath.

Concentration characteristics of the KIER solar furnace are analyzed with a heat flux measurement technique. Total heat capacity of 40kW was confirmed within 1.04% average error, and the normalized maximum heat flux of 3,452 $kW/m^2$ was proved. Non-Gaussian flux distribution in the vertical direction implies that reflectors should not be random rather inclined downwards. Moreover, we characterized flux distribution variations with furnace blind opening ratio, distance from the focal plane, and misalignment of the measurement system. Based on the results, the heat flux distribution can be simply estimated once reflectivity and direct normal insolation values are known. This study will be helpful to the design and the performance evaluation of receivers or chemical reactors.

Textile industry of Domestic has been descended in the sector of design, brand, recognition comparing with developed countries. And products of middle and low price do not have competitiveness against developing countries. In addition, textile industry market is changing from the provider market-oriented to consumer-driven market. RFID(Radio Frequency Identification) is the core technology to correspond in the these environmental change. RFID is a technology that is used to communicate with identified objects using radio waves, so that the objects can be recognized, tracked and traced. In this study, we reviewed characteristic and present condition of domestic textile industry and newest technology aspect of RFID. Also, we suggested application plan of RFID technology in textile industry through the analyzing RFID application case of domestic and outside the country textile industry.

우주측지 정밀도 향상을 위해 대류층 지연오차의 정확한 산출은 필수적이다. 한국천문연구원은 GPS 자료를 이용하여 대류층 지연오차 요인인 대기 중의 수증기량을 정확히 산출하는 연구를 수행하고 있다. 또한, 1999년부터 GPS 관측을 시작한 이래로 10년 이상의 연속 관측자료를 보유하고 있다. 이 연구에서는2000년부터 2008년까지 한국천문연구원의 GPS 상시관측소 5곳(서울, 대전, 목포, 밀양, 속초)의 GPS 가강수량을 산출하고 이들의 다년간 변화경향을 분석하였다. 산출된 GPS 가강수량을 라디오존데 관측값과 비교하여 신뢰도 검증하였다. 선형회귀방법을 통하여 GPS 가강수량에 대한 경향을 분석하면 관측 지역마다 기울기의 차는 있으나 전체적으로 시간이 지날수록 GPS 가강수량이 증가하는 경향을 보였다. 해당 기간동안 GPS 가강수량의 연간 변화량은 평균 0.20mm 증가하였고 목포의 경우 0.25mm로 가장 큰 변화량을 보였으며 서울이 0.16mm로 가장 작은 변화량을 보였다. 여름철 연간 변화량은 평균 0.32mm 증가하였고 겨울철은 평균 0.08mm 감소하였다. 일반적으로 기온이 상승하면 상대습도가 내려가 수증기의 증발이 활발해져 대기중의 수증기량이 증가한다. 최근 10년간 기상청의 기온은 매해 평균 $0.16^{\circ}C$씩 증가하였으며 대기 중의 수증기량과 직접적으로 연관되어 있는 GPS 가강수량의 변화 경향과 유사함을 확인하였다.

This paper implements RFID(radio-frequency identification)System to which the system was apply SS(Spread Spectrum) method. The system designed by using the algorithm for microprocessor with PLL of the receiver, PN spread, modulation and demodulation of the transceiver, and transistor amplifier for the output of stabilized BPSK (Binary Phase Shift Keying) signal. furthermore, it reduced the interference of the signal by designing the micro-strip narrow banded patch antenna, which is convenient for printing and producing, and decreased the volume of filter size in the system. It is also designed for the lower powered system with the possible application to UHF band of $860\sim930MHz$ for the international standard frequency band, which is the quota share of RFID distribution system.

In this paper, we analyze and simulate the performance of a pilot signal detection algorithm based on fast Fourier transform (FFT) for several system parameters in order to detect advanced television system committee digital television (ATSC DTV) signals. Requirements for detecting DTV signals are analyzed. And the detection performance is compared according to sensing frequency and time. Form the simulation results, it is confirmed that the signal detection performance increases as the sensing frequency rises. The results of this paper can be applied for implementing cognitive radio (CR) systems in the frequency band of DTV signals.

The public broadcasting in Korea are currently financed primarily through license fees paid by anyone who holds a TV set. This paper aimed for other options; How can we have a stable cash flow for public broadcasting account for right incentives, lack of sufficient government intervention, efficiency and quality? As this paper shows, bringing taxes more efficient and fairer, while a solid foundation for the public broadcasting finance; combined with an incentive based payment system this may be a sensible alternative to the forthcoming poll tax.
