The proportion of elderly people in traffic accidents is increasing in Japan. It is therefore necessary to make transportation for the elderly safer by automating the electric wheelchair. Technologies that estimate the vehicle position and orientation are required to realize automated driving. One technology is simultaneous localization and mapping. This technology computes the current self-position by comparing a map and data from a sensor. The present study used the normal distributions transform algorithm for self-position estimation. The main aim of the study was to construct a three dimensional map required for self-position estimation on a sidewalk. For the evaluation of this map, self-position estimation was performed using the map and estimated distances were compared with actual distances measured, by a laser range finder. Results show a difference between the actual position and estimated position of approximately 0.05 m in the area of a sidewalk. The self position estimation on the sidewalk using the normal distributions transform was thus accurate. Future work will focus on a next-generation map that contains point data for the upper part of a building.

[Purpose] There have been concerns that the availability and usage of electrophysical agents have decreased, based on data from cross-sectional surveys. The aim of this study was to conduct the first five-year follow-up longitudinal survey to determine the changes in the availability and usage of electrophysical agents in Nagano Prefecture, Japan. [Participants and Methods] This longitudinal observational study employed the same postal questionnaire survey of practicing clinicians in 2014 and 2019. A total of 22 modalities had been selected for inclusion in the questionnaire based on what is used in clinical facilities and hospitals. [Results] The response rate was 71% and 63% for 2014 and 2019, respectively. The modalities that were high in availability and usage for both 2014 and 2019 were hot packs, ultrasound, cryotherapy and low frequency. While most modalities demonstrated a decreased trend in usage, electrical stimulation devices increased from 2014 to 2019. The results also demonstrated that usage was affected by gender (males greater than females), years of experience (older greater than younger), qualifications (diplomas greater than degrees), and confidence (confident greater than non-confident). [Conclusion] Our results may assist educators with designing educational curricula that is consistent with the needs of clinicians.

[Purpose] The aim of this study was to investigate the availability, usage, and factors affecting usage of electrophysical agents by physical therapists in Nagano Prefecture, Japan. [Subjects and Methods] Questionnaires were sent to all 1,571 physical therapists working in 245 institutions within Nagano Prefecture. A total of 1,110 questionnaires were returned, out of which 1,099 (70%) questionnaires containing valid responses were analyzed. Frequencies and percentages were calculated for 22 modalities with regards to availability, usage, rate of usage, and confidence level in usage. Factors affecting usage and the relationship between rate of usage and confidence level (Spearman’s rho) were also determined. [Results] The top three responses for the various outcome measures were as follows: (1) hot packs (88%), low frequency stimulators (76%), and ultrasound (68%) for availability; (2) hot packs (72%), ultrasound (61%), and cold packs (59%) for usage; (3) hot packs (75%), cold spray (49%), and ultrasound (44%) for confidence in usage; and (4) equipment availability (80%), past experience (79%), and research evidence (78%) for factors affecting usage. There was a significant positive relationship between confidence and usage for all modalities, except for ultraviolet radiation, iontophoresis, and magnetic field. [Conclusion] Usage was strongly correlated with confidence, with the top three used modalities also being the ones with the highest confidence in usage.
