Tosolve complex and diverse social problems and ensure the quality of life of individuals, social robots that can interact with humans are attracting attention. In the past, robots were recognized as beings that provide labor force as they put into industrial sites on behalf of humans. However, the concept of todays robot has been extended to social robots that coexist with humans and enable social interaction with the advent of Smart technology, which is considered an important driver in most industries. Specifically, there are service robots that respond to customers, the robots that have the purpose of edutainment, and the emotionalrobots that can interact with humans intimately. However, popularization of robots is not felt despite the current information environment in the modern ICT service environment and the 4th industrial revolution. Considering social interaction with users which is an important function of social robots, not only the technology of the robots but also other factors should be considered. The design elements of the robot are more important than other factors tomake consumers purchase essentially a social robot. In fact, existing studies on social robots are at the level of proposing robot development methodology or testing the effects provided by social robots to users in pieces. On the other hand, consumer emotions felt from the robots appearance has an important influence in the process of forming users perception, reasoning, evaluation and expectation. Furthermore, it can affect attitude toward robots and good feeling and performance reasoning, etc. Therefore, this study aims to verify the effect of appearance of social robot and consumer emotions on consumers attitude toward social robot. At this time, a social robot design evaluation model is constructed by combining heterogeneous data from different sources. Specifically, the three quantitative indicator data for the appearance of social robots from the ABOT Database is included in the model. The consumer emotions of social robot design has been collected through (1) the existing design evaluation literature and (2) online buzzsuch as product reviews and blogs, (3) qualitative interviews for social robot design. Later, we collected the score of consumer emotions and attitudes toward various social robots through a large-scale consumer survey. First, we have derived the six major dimensions of consumer emotions for 23 pieces of detailed emotions through dimension reduction methodology. Then, statistical analysis was performed to verify the effect of derived consumer emotionson attitude toward social robots. Finally, the moderated regression analysis was performed to verify the effect of quantitatively collected indicators of social robot appearance on the relationship between consumer emotions and attitudes toward social robots. Interestingly, several significant moderation effects were identified, these effects are visualized with two-way interaction effect to interpret them from multidisciplinary perspectives. This study has theoretical contributions from the perspective of empirically verifying all stages from technical properties to consumers emotion and attitudes toward social robots by linking the data from heterogeneous sources. It has practical significance that the result helps to develop the design guidelines based on consumer emotions in the design stage of social robot development.

본 논문은 압축센싱을 위한 광대역 수신기를 0.13μm SiGe 프로세스를 사용하여 집적화 구현한 것이다. 제안 된 수신기는 광대역 능동 발룬으로 구성된 2-18 GHz 대역 구동 증폭기, 이중 평형 수동 믹서, 그리고 출력 구동 버퍼를 포함하는 700 MHz 4 단 가변 이득 증폭기 (VGA)로 구성된다. 광대역 버퍼는 -10dB 미만의 반사 손실로 20GHz 이상의 대역폭을 달성하기 위해 RF 입력단에서 의사 전송선로를 이용하였다. IF VGA는 15.49 dB에서 34.74 dB의 가변 이득을 조정할 수 있다. 구현 된 수신기는 통합된 64 비트 SPI 스캔 체인 회로에 의해 제어된다. 서브-나이퀴스트 샘플링 기능은 LO 신호용 외부 PRBS 생성기를 통해 검증되었다. 제작된 수신기의 크기는 0.5 × 0.77㎟이고, 2.5V 전원에서 약 27mA의 DC 전류를 소비한다. In this paper, an integrated broadband receiver capable of the compressed sensing is implemented using 0.13μm SiGe process. The proposed receiver consists of a 2-18 GHz driving amplifier configured as the broadband active balun, a double-balanced passive mixer, and a 700-MHz four stage variable gain amplifier (VGA) including an output driving buffer. The broadband buffer utilizes the pseudo transmission-line at the RF input to achieve the more than 20 GHz of the bandwidth with the return loss less than -10 dB. The IF VGA is capable of varying the gain from 15.5 dB to 34.7 dB. The implemented receiver is controlled by an integrated 64-bit SPI scan-chain block. The sub-Nyquist sampling operation has been verified with an external PRBS generator as the LO signal. The receiver chip size is 0.5 × 0.77㎟, and consumes around 27 mA of DC current under 2.5V supply voltage.

무인수상정 경로점 추종을 위한 강화학습 기반 Dynamic Window Approach
허진영,하지수,이준식,유재관,권용진,Heo, Jinyeong,Ha, Jeesoo,Lee, Junsik,Ryu, Jaekwan,Kwon, Yongjin 한국군사과학기술학회 2021 한국군사과학기술학회지 Vol.24 No.1
Recently, autonomous navigation technology is actively being developed due to the increasing demand of an unmanned surface vehicle(USV). Local planning is essential for the USV to safely reach its destination along paths. the dynamic window approach(DWA) algorithm is a well-known navigation scheme as a local path planning. However, the existing DWA algorithm does not consider path line tracking, and the fixed weight coefficient of the evaluation function, which is a core part, cannot provide flexible path planning for all situations. Therefore, in this paper, we propose a new DWA algorithm that can follow path lines in all situations. Fixed weight coefficients were trained using reinforcement learning(RL) which has been actively studied recently. We implemented the simulation and compared the existing DWA algorithm with the DWA algorithm proposed in this paper. As a result, we confirmed the effectiveness of the proposed algorithm.
