Evolving Adaptive Group Behavior in a Multi-Robot System
Saori Iwanaga,Kazuhiro Ohkura,Tomoya Matsuda 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
The field of multi-robot systems is sometimes called swarn robotics when the systems consist of many simple autonomous robots. However, each robot is usually assumed to have no learning mechanism for adapting to an embedded changing environment. Therefore, collective behavior is expected to emerge in the system only through interactions among the robots. This implies that they cannot be coordinating as a group. In this study, an evolutionary robotics approach is applied empirically to a multi-robot system to realize autonomous task allocation behavior as a kind of intelligent swarm robotics. Although artificial evolution has proven to be a promising approach to coordinate the controller of an autonomous robot, its effectiveness in developing beneficial collective behavior in a multi-robot system has not been verified. Serveral computer simulations are conducted to examine how artificial evolution contributes to autonomous task allocation in a multi-robot system.
Recent Findings about the Yersinia enterocolitica Phage Shock Protein Response
Saori Yamaguchi,Andrew J. Darwin 한국미생물학회 2012 The journal of microbiology Vol.50 No.1
The phage shock protein (Psp) system is a conserved extracytoplasmic stress response in bacteria that is essential for virulence of the human pathogen Yersinia enterocolitica. This article summarizes some recent findings about Y. enterocolitica Psp system function. Increased psp gene expression requires the transcription factor PspF, but under non-inducing conditions PspF is inhibited by an interaction with another protein, PspA, in the cytoplasm. A Psp-inducing stimulus causes PspA to relocate to the cytoplasmic membrane, freeing PspF to induce psp gene expression. This PspA relocation requires the integral cytoplasmic membrane proteins, PspB and PspC, which might sense an inducing trigger and sequester PspA by direct interaction. The subsequent induction of psp gene expression increases the PspA concentration, which also allows it to contact the membrane directly, perhaps for its physiological function. Mutational analysis of the PspB and PspC proteins has revealed that they both positively and negatively regulate psp gene expression and has also identified PspC domains associated with each function. We also compare the contrasting physiological roles of the Psp system in the virulence of Y. enterocolitica and Salmonella enterica sv. Typhimurium (S. Typhimurium). In S. Typhimurium, PspA maintains the proton motive force, which provides the energy needed to drive ion importers required for survival within macrophages. In contrast, in the extracellular pathogen Y. enterocolitica, PspB and PspC, but not PspA, are the Psp components needed for virulence. PspBC protect Y. enterocolitica from damage caused by the secretin component of its type 3 secretion system, an essential virulence factor.
The Pacific Ocean Route Optimization by Pittsburgh-style Learning Classifier System
Saori Iseya,Keiji Sato,Kiyohiko Hattori,Keiki Takadama 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
This paper proposes the optimization method which extends Pittsburg-style Learning Classifier System(LCS) for Pacific Ocean route. In detail, the following extensions are introduced:(1) the unrealistic route deletion, (2) the route integration, and (3) the route rest time minimization and the anchor order change. To investigate the effectiveness of the proposed methods, this paper applies them into LCS to optimize the Pacific Ocean liner route using the actual transportation data. The intensive simulations have revealed following indications: (1) the generated routes using the proposed methods can produce the feasible routes that are hard to be found by the conventional method; and (2) our proposed methods contribute to creating the effective route set which has the short rest time, a small number of vessels, and high profit.

The purpose of this study is to investigate the influence of self-brand connections (SBCs) on brand attachment. The author proposes two types of SBCs: those that are created through marketing systems (brand-based self-brand connections, [BBSBC]) and those that are created by the individual (consumer-based self-brand connections, [CBSBC]). To investigate the influence of these SBCs on brand attachment, this study analyses survey data through the use of structural equation modelling. The results show that both BBSBC and CBSBC have positive effects on brand attachment but that the influence of CBSBC is stronger. Furthermore, in the context of durable consumer goods, CBSBC have a stronger effect on brand attachment when fast-moving consumer goods and services are compared. For fast-moving goods, BBSBC and CBSBC affect brand attachment at the same level.

Objectives: Few studies examined the association between deterioration of masticatory ability assessed by objective marker and physical function. Therefore, we examined the association between salivary flow rate which is one of the objective and surrogate marker of masticatory ability and lower Timed Up & Go (TUG) performance which is one of major measurement of physical function among aging Japanese. Methods: This cross-sectional study enrolled 464 Japanese aged 60e84 years old. Participants chewed tasteless and odorless gum for 5 min, calculated stimulated salivary flow rate (g/min) during all chews. The 3 m TUG was conducted, and 75th percentile value (6.8 s for men and 7.0 s for women) or higher was defined as lower TUG performance. Logistic regression analysis was used to examine the association between stimulated salivary flow rate and lower TUG performance. Results: We found that the stimulated salivary flow rate tended to be negatively associated with the TUG time. We also observed significant negative association between stimulated salivary flow rate and lower TUG performance; the multivariable-adjusted OR (95% confidence interval, CIs) of lower TUG performance for the highest quartile of stimulated salivary flow rate compared with the lowest quartile was 0.34 (0.16-0.69, P for trend = 0.02). Further adjusting for BMI, the association was attenuated but remaind significant; the OR (95% CIs) in highest quartile was 0.37 (0.18-0.76, P for trend = 0.04). Conclusions: Higher stimulated salivary flow, which means well masticatory ability, was inversely associated with lower TUG performance in the aging Japanese population.
1876년 제1차 수신사를 통한 한일 의학교류: 우두법을 중심으로
SAORI HASEGAWA,최규진 동아시아일본학회 2022 일본문화연구 Vol.- No.82
본 연구는 1876년 제1차 수신사 파견 과정에서 이루어진 한일 의학교류에 대해서 살펴본 것이다. 특히 현석운과 시마다 슈카이, 박영선과 준텐도의원・사네요시 야스즈미, 홍현보와 야노 요시테쓰 사이에 이루어진 긴밀한 소통과 협력에 주목했다. 이러한 조선의 지식인들과 일본 의사들 간에 이루어진 교류를 통해 당시 조선에 서양의학 도입 시도가 이루어지고 있었음을 확인할 수 있었다. 아울러 지금까지 박영선이 수신사행에서 돌아와 지석영에게 『종두귀감』을 전달한 것이 계기가 됐다는 단편적인 에피소드처럼 설명돼왔던 우두법 도입의 역사가 사실은 박영선을 비롯해 조선과 일본의 여러 인물이 적극적으로 기여한 결과였다는 점도 확인할 수 있었다. 결론적으로, 이러한 의학교류를 통해 일본은 제생의원 설립을 추진하며 조선에 대한 내밀한 접근을 전개하였고, 조선의 개혁적 지식인들은 우두법 도입을 필두로 조선 사회의 근대적 변화를 도모했다. 즉 1876년 제1차 수신사를 통한 한일 의학교류는 이러한 두 흐름이 시작되는 기점이라고 할 수 있다.
