Journal of Civil Engineering and Architecture 2013年第7期7卷 827-832页

作者： Masako Sakai Akiko Watanabe Graduate School of Science and Technology for Future Life Tokyo Denki University Tokyo 120-8551 Japan Department of Architecture Tokyo Denki University Tokyo 120-8551 Japan

Recently, Japan has experienced a low birthrate and an aging population. The development of communication robots, such as cleaning and a care-giver robot, has been progressing. Care-giver robots provide daily assistance, including contacting emergency services. This study is part of the ＂study on planning techniques of living space in harmony with robots＂, and focused on the elderly. Minimum distance was the subjects felt ＂I do not want any more approached＂. Subjects were 21 elderly persons （eight males and thirteen females）, aged 66-86 years. The experimental room was an assembly room in a public accommodation （14 m× 6.5 m）. The small mobile robot used in this experiment was external form dimensions of 120 mm （W）× 130 mm （D）× 70 mm （H）, In this experiment, considering the personal space as the small mobile robot is watching robot without support function for person. The robot moved toward standing or sitting subjects at constant velocities from a distance 5 m apart. Research factors are 5 angles （0°, 45°, 90°, 135° and 180°） and 2 speeds （0.08 m/s and 0.24 m/s）.

Prevaccination Antibody Confers Additional Immune Responses to Repeated Yearly Influenza Vaccination in an elderly Population

引用

World Journal of Vaccines 2022年第2期12卷 11-19页

Annual vaccination is necessary to maintain humoral immunity in the elderly population. However, the factors influencing the response to influenza vaccination have not been completely identified. The aim of this study was to explore the factors that influenced antibody responses to repeated vaccination using measures that were both objective and quantitative. A total of 111 volunteers aged > 61 years were vaccinated subcutaneously with one dose of influenza vaccine from the 2005-2006 season through the 2009-2010 season. The factors that influenced antibody responses after vaccination were evaluated. The seroprotection rates (PRs) were significantly higher in responders (subjects with a higher antibody titer in the 2005-2006 season) than in nonresponders only in the 2006-2007 and 2007-2008 seasons. PRs after vaccination were significantly higher in seropositive individuals (subjects with a higher prevaccination antibody titer in the 2006-2007 season) than in seronegative individuals for all three virus strains in almost all of the 5 years. Age, gender, and vaccination in the 2004-2005 season did not influence the response. These results suggest that an immune response at a certain time point would predict immune responses only in the near future. However, prevaccination antibody titer in the following season is the ideal predictor for future responses that last over several influenza seasons.
