본 연구에서는 멀티플랫폼 환경에서 지상파TV의 채널브랜드자산이 시청자들의 지상파 콘텐츠 선택과 이용에 미치는 영향을 점검하였다. 연구결과, 지상파TV 채널브랜드자산이 멀티플랫폼 상 지상파TV 콘텐츠 이용 정도에 미치는 영향은 SBS인지도만이 지상파TV 콘텐츠 이용 정도에 유의미한 영향을 미치는 것으로 나타났다. 지상파TV 채널브랜드자산이 지상파 콘텐츠 시청 매체의 다양성에 미치는 영향은 어떤 채널에서도 유의미하지 않은 것으로 나타났으며, 지상파 콘텐츠 시청 플랫폼 유형별 이용에 미치는 영향은 지상파TV 채널별로 플랫폼 유형에 따라 차이를 보이는 것으로 나타났다. 더불어, 지상파TV 채널브랜드자산이 지상파 콘텐츠 이용 장르의 다양성에 미치는 영향은 KBS인지도와 SBS인지도만이 지상파TV 콘텐츠 이용 장르의 다양성에 유의미한 영향을 미치는 것으로 나타났다. 마지막으로, 지상파 채널브랜드자산이 지상파TV 콘텐츠 장르 유형별 이용에 미치는 영향은 각 채널별로 특정 장르유형을 중심으로 다르게 나타났다. 본 연구의 결과는 채널브랜드자산이 멀티플랫폼 상에서 시청자들의 지상파TV 콘텐츠 선택 및 이용에 부분적이나마 영향을 미친다는 것을 제시해주며, 이는 경쟁적인 매체환경에서 방송채널의 경쟁력 강화를 위해 의미있는 시사점을 제공해 준다.

As public space such as plaza and square in the compact city type multi-use complex is a social public space that various communication and cultural exchange take places in city environment. The purpose of this study is to analyse and categorize the design elements as a valuation basis for the public space in the compact city type multi-use complex. The scope of contents of this study is focused on the Central City, COEX and Western Dome facilities in Korea. This study review based on the previous studies and statistical analysis about questionnaires obtained from 131 users of three facilities were conducted for this study. The results of the survey as follows accessibility, comfort, exchange were extracted as the aspects for evaluation for functional activity and connection, openness, hierarchy were extracted as the aspects for evaluation for space formation. The K facility's priority aspect is the accessibility and the S and the W facilities' are the openness.

It is important thing that air quality affects human health. And It is more important thing that Indoor Air Quality more affects human health than Outdoor Air Quality. The cause of that is indoor air pollutants are more absorbed than outdoor air pollutants. By the way, in case of Multi-use facility for example office, department store, school etc., it has a feature that there are more people than any other buildings. therethrough, effects of Indoor Air Quality of Multi-use facility affect more people's health than Indoor Air Quality of any other buildings. However, in multi-use facility, specifically retail store, chemical treated materials are used for interior finishing, showcase finishing and product finishing because esthetic element is more added for detention of customer. Consequently, in place where demands brisk sales, possibility that indoor air is polluted by VOCs is high. This study considered retail store's Indoor Air Quality. as result of experiment, figure of department store's air pollution exceed about 5~20 times in guideline of multi-use facility's Indoor Air Quality in any kind of shop of department store (guideline : $500{\mu}g/m^3$).

As a preliminary step for developing vulnerability assessment model of terrorism, this study aims to deduce and classify architectural design elements of multi-use buildings to protect them from terrorism using explosives. For these objectives, eleven domestic and foreign guidelines of anti-terrorism, including RVS which is one of the commonly used tools for assessing vulnerability to terrorism, were analyzed. As results, 2 scenarios of explosive attack, 4 layers of defense, and 58 architectural design elements for risk assessment of terrorism were deduced. And the design elements were categorized into 18 groups based on their purpose and function to take into account the supplementary effects among them. Then, the design measures applicable for each element were classified into several grades on the basis of its protection or risk level. Lastly, 11 multi-use buildings were selected and investigated how the elements suggested in this study were applied to them.

The paper presents a multi-objective optimization strategy for a multi-type sensor placement for Structural Health Monitoring (SHM) of long span bridges. The problem is formulated for simultaneous placement of strain sensors and accelerometers (heterogeneous network) based on application demands for SHM system. Modal Identification (MI) and Accurate Mode Shape Expansion (AMSE) were chosen as the application demands for SHM. The optimization problem is solved through the use of integer Genetic Algorithm (GA) to maximize a common metric to ensure adequate MI and AMSE. The performance of the joint optimization problem solved by GA is compared with other established methods for homogenous sensor placement. The results indicate that the use of a multi-type sensor system can improve the quality of SHM. It has also been demonstrated that use of GA improves the overall quality of the sensor placement compared to other methods for optimization of sensor placement.

Currently, geothermal heat pump systems are being installed in new official and commercial building, welfare facilities, and school but there are a few cases for the housing heat sink in Korea. The reason is that there are no progressive taxes for the household electrical use, no actual output for the application of geothermal technology, high initial investment. For the overall use in multi family apartment such as the Green Home etc, technology development and building of the relevant research team need to be done through preliminary study. Core subjects for overall use include cooling heating load estimation for the multi family apartment, economical efficiency of the geothermal cooling and heating system, design and construction technology of the geothermal cooling and heating system for the multi family apartment, commercialization plan, and state of the art analysis. Selection of the detailed subjects with respect to core subject, driving schedule and commercialization plan, driving system, presentation of the utilization plan.

This paper presents a new multi-machine robust control based on an electric differential system for electric vehicle (EV) applications which is composed of four in-wheel permanent magnet synchronous motors. It is based on a new master-slave direct torque control (DTC) algorithm, which is used for the control of bi-machine traction systems based on a speed model reference adaptive system observer. The use of an electric differential in the design of a new EV constitutes a technological breakthrough. A classical system with a multi-inverter and a multi-machine comprises a three-phase inverter for each machine to be controlled. Another approach consists of only one three-phase inverter for several permanent magnet synchronous machines. The control of multi-machine single-inverter systems is the subject of this study. Several methods have been proposed for the control of multi-machine single-inverter systems. In this study, a new master-slave based DTC strategy is developed to generate an electric differential system. The entire system is simulated by Matlab/Simulink. The simulation results show the effectiveness of the new multi-machine robust control based on an electric differential system for use in EV applications.

This paper presents a multi-phase ring VCO for low-cost, low-power GPS receiver. In the RF band used in GPS, L1 band is now in commercial-use and L2,L5 are predicting to be commercial-use soon. Thus Wide band PLL and Cost-effective IC solutions are required for future multi-band GPS receiver that received three types band at once. A new PLL architecture for multi-band GPS application is proposed. Ring VCO is even smaller than LC-VCO and a good alternative for low-cost solution. Proposed multi-phase ring VCO offers wide frequency range covering L1, L2, and L5 band, 20% reduction of area, 23% reduction of PLL power and can generate I/Q without extra I/Q generator.

In this paper, a communication module between Relay agents in a multi-agent system based power distribution network protection system is realized using DNP3.0(Distributed Network Protocol), which is the standard communication protocol of distribution automation system in KEPCO. The key words for agent communication in the multi-agent based protection system are defined and represented by use of DNP application function code. The communication module developed based on the proposed communication scheme is tested by use of the Communication Test Harness, a test tool for DNP protocol, then used to the multi-agent system based power distribution net work protection system.
