At the dawn of the fourth industrial revolution, the healthcare industry is experiencing a momentous shift in the direction of increasingly pervasive technologization of care. If, up until the 2000s, imagining healthcare provided by robots was a purely futuristic fantasy, today, such a scenario is in fact a concrete reality, especially in some countries, such as Japan, where nursing care is largely delivered by assistive and social robots in both public and private healthcare settings, as well as in home care. This revolution in the context of care, already underway in many countries and destined to take place soon on a global scale, raises obvious ethical issues, related primarily to the progressive dehumanization of healthcare, a process which, moreover, has undergone an important acceleration following the outbreak of the COVID-19 pandemic, which has made it necessary to devise new systems to deliver healthcare services while minimizing interhuman contact. According to leading industry experts, nurses will be the primary users of healthcare robots in the short term. The aim of this study is to provide a general overview, through a scoping review approach, of the most relevant ethical issues that have emerged in the nursing care field in relation to the increasingly decisive role that service robots play in the provision of care. Specifically, through the adoption of the population-concept-context framework, we formulated this broad question: what are the most relevant ethical issues directly impacting clinical practice that arise in nursing care delivered by assistive and social robots? We conducted the review according to the five-step methodology outlined by Arksey and O'Malley. The first two steps, formulating the main research question and carrying out the literature search, were performed based on the population-context-concept (PCC) framework suggested by the Joanna Briggs Institute. Starting from an initial quota of 2,328 scientific papers, we performed an initial screening through a computer system by eliminating duplicated and non-English language articles. The next step consisted of selection based on a reading of the titles and abstracts, adopting four precise exclusion criteria: articles related to a nonnursing environment, articles dealing with bioethical aspects in a marginal way, articles related to technological devices other than robots, and articles that did not treat the dynamics of human-robot relationships in depth. Of the 2,328 titles and abstracts screened, we included 14. The results of the 14 papers revealed the existence of nonnegligible difficulties in the integration of robotic systems within nursing, leading to a lively search for new theoretical ethical frameworks, in which robots can find a place; concurrent with this exploration are the frantic attempts to identify the best ethical design system applicable to robots who work alongside nurses in hospital wards. In the final part of the paper, we also proposed considerations about the Italian nursing context and the legal implications of nursing care provided by robots in light of the Italian legislative panorama. Regarding future perspectives, this paper offers insights regarding robot engagement strategies within nursing. [ABSTRACT FROM AUTHOR]

Objective: To (1) examine the potentiality of using the robot PARO to mediate care provided by the family and (2) identify problems when utilizing PARO in the home context. Methods: Family members of 7 households were asked to use PARO for at least three times per week, over 1 to 3 months. Research data, including standardized assessments, interviews, and observations, were collected at initial and subsequent monthly visits. Collected data were analyzed through descriptive statistics and inductive thematic content analysis. Results: Out of the seven participants, five responded positively to PARO, thereby achieving their goals of improving activity engagement, relaxation, a respite from supervision, and improved mood. A positive initial interaction with PARO showed continued interest to it. Participants were observed to communicate with caregivers and relate to PARO. Discussion: The application of PARO at home is possibly influenced by the persons' initial level of interest toward PARO. It is crucial to perform careful observation and assessment before deciding to use PARO within the home context to support the life of older persons with dementia. [ABSTRACT FROM AUTHOR]

Aim: This study aimed to describe the interactions between healthcare robots and older persons in two selected institutions. Methods: A qualitative descriptive analysis study using simultaneous observations of healthcare robot and older person interactions was conducted at two healthcare institutions in Japan. The Pepper robot equipped with Care Prevention Gymnastics Exercise programs was used in two situations: (a) exercise regimen led by Pepper; and (b) interactive dialogue between Pepper and older persons during the exercise process. These interactions were recorded using audiovisual equipment and analyzed using content analysis thereby revealing four thematic categories. Interpretation and discussion were structured based on assumptions of the Transactive Relationship Theory of Nursing. Results: The analysis revealed four thematic categories: (a) intermediary participation of healthcare practitioners; (b) technologies of care for practice; (c) human-robot interactions involving artificial intelligence; and (d) valuing safety in nursing through technology. Conclusion: Interactions between healthcare robots and older persons may improve quality of care. However, issues regarding fidelity and functionality of dialogic conversations, and ensuring safety and security of using healthcare robots are recognized as critical nursing practice concerns in healthcare robot use in institutional settings.

Encouraging students to actively ask questions during lectures is a formidable challenge that can be addressed through innovative use of information technology. We developed a robotic system that allows students in a lecture to collaboratively decide questions to be asked by a humanoid robot. To verify whether the system reduces hesitation to ask questions during lectures, 62 university students were divided into two groups, and each attended two different mock lectures on the Nobel Prize in Physics. Two lectures were conducted with and without the proposed system in counterbalanced order. Results suggested that students who were usually hesitant to ask questions during lectures became less hesitant to ask questions face‐to‐face when they could use the proposed system. Moreover, the perceived activeness in the lectures increased when using the system. Multiple regression analyses revealed that certain student actions, particularly tweeting and showing agreement with the questions posted by others, were correlated with an increase in perceived activeness. Lay Description: What is already known about this topic: In‐class student passivity is a widespread problem at many schools.Information and robot technologies have focused on addressing student passivity.Existing audience response systems are supportive but with limited degrees of freedom.It is unclear how these systems can encourage face‐to‐face student interactions. What this paper adds: We developed a system for in‐class students to ask questions collaboratively via a humanoid robot.Japanese undergraduates attended two experimental mock lectures with and without the proposed system.Hesitant students felt less hesitation asking questions face‐to‐face in the class with our system. The implications of study findings for practitioners: Significant effects of the robotic system on lecture participation are shown.In particular, it can encourage hesitant students to actively participate in class.Lecturer–student supported communication expected to promote experiences without it.Experiments in real educational settings are recommended to verify system usefulness.

• Surveys for home-care robots were conducted in Japan, Ireland, and Finland. • The study built a model of ethical perceptions regarding the use of home-care robots. • Our final model had explanatory power across countries with different backgrounds. • This model can also be applied to explain ethical perceptions by attributes. To date, research on ethical issues regarding care robots for older adults, family caregivers, and care workers has not progressed sufficiently. This study aimed to build a model that universally explains the relationship between the use of care robots and ethical awareness, such as regarding personal information and privacy protection in home care. We examined data obtained from cross-sectional surveys conducted in Japan (n=528), Ireland (n=296), and Finland (n=180). We performed a confirmatory factor analysis by using responses to 11 items related to the ethical use of care robots. We evaluated the model based on the chi-square to degrees of freedom ratio, the comparative fit index, and the root mean square error of approximation. Subsequently, we compared the model with the Akaike's information criterion. Ten items were adopted in the final model. There were 4 factors in the model: 'acquisition of personal information', 'use of personal information for medical and long-term care', 'secondary use of personal information', and 'participation in research and development'. All factor loadings of the final model ranged between 0.63 and 0.92, which were greater than 0.6, showing that the factors had a high influence on the model. The final model was applied to each country; the fit was relatively good in Finland and poor in Ireland. Although the three countries have different geographies, cultures, demographics, and systems, this study showed that the impact of ethical issues regarding the use of care robots in home care can be universally explained by the same model.

Background: Growing evidence for the advantages of robotic pancreatoduodenectomy (RPD) has been demonstrated internationally. However, there has been no structured training program for RPD in Japan. Herein, we present the surgical training model of RPD and a standardized protocol for surgical technique. Methods: The surgical training model and surgical technique were standardized in order to implement RPD safely, based on the Dutch training system collaborated with the University of Pittsburgh Medical Center. Results: The surgical training model included various trainings such as basic robotic training, simulation training, biotissue training, and a surgical video review. Furthermore, a standardized protocol on the surgical technique was established to understand the tips, tricks, and pitfalls of RPD. Conclusions: Safe implementation of RPD can be achieved through the completion of a structured training program and learning surgical technique. A nationwide structured training system should be developed to implement the program safely in Japan. [ABSTRACT FROM AUTHOR]

Purpose: There are no definitive prognostic factors for patients with pathological Grade Group 5 (pGG 5) prostate cancer (PCa) undergoing robot-associated radical prostatectomy (RARP). This study aimed to explore the prognostic factors among patients with pGG 5 PCa in a large Japanese cohort (MSUG94)., Methods: This retrospective, multi-institutional cohort study was conducted between 2012 and 2021 at ten centers in Japan and included 3195 patients. Patients with clinically metastatic PCa (cN1 or cM1) and those receiving neoadjuvant and/or adjuvant therapy were excluded. Finally, 217 patients with pGG5 PCa were analyzed., Results: The median follow-up period was 28.0 months. The 3- and 5-year biochemical recurrence-free survival (BCRFS) rates of the overall population were 66.1% and 57.7%, respectively. The optimal threshold value (47.2%) for the percentage of positive cancer cores (PPCC) with any GG by systematic biopsy was chosen based on receiver operating characteristic curve analysis. Univariate analysis revealed that the prostate-specific antigen level at diagnosis, pT, pN, positive surgical margins (PSMs), lymphovascular invasion, and PPCC were independent prognostic factors for BCRFS. A multivariate analysis revealed that PSMs and PPCC were independent prognostic factors for BCRFS. Using these two predictors, we stratified BCRFS, metastasis-free survival (MFS), and castration-resistant PCa-free survival (CRPC-FS) among patients with pGG 5 PCa., Conclusion: The combination of PSMs and PPCC may be an important predictor of BCRFS, MFS, and CRPC-FS in patients with pGG 5 PCa undergoing RARP., (© 2024.

Background: The quality of life of patients is an important consideration when selecting treatments for localized prostate cancer (PCa). We retrospectively compared sexual function after robot-assisted radical prostatectomy (RARP) and carbon-ion radiotherapy (CIRT) using propensity score matching., Methods: In total, 127 Japanese PCa patients treated with RARP and 190 treated with CIRT monotherapy were evaluated. We evaluated the Expanded Prostate Cancer Index Composite (EPIC) score before treatment and 12 and 24 months after treatment. After propensity score matching, data from 101 patients from each group were analyzed. The study protocol was approved by the Institutional Review Board of Gunma University Hospital (no. IRB2020-050, 1839)., Results: After propensity score matching, the mean EPIC sexual function summary scores in the RARP and CIRT groups were 46.4 and 48.2, respectively. At 12 and 24 months after treatment, these scores were 27.9 (39.9% decrease) and 28.2 (39.2% decrease) in the RARP group and 41.4 (14.1% decrease) and 41.6 (13.7% decrease) in the CIRT group, respectively. Both groups demonstrated significantly decreased scores after 12 and 24 months of treatment compared to before treatment (all p < 0.05). At 12 and 24 months, the sexual function summary score was significantly higher in the CIRT group than in the RARP group (p < 0.001)., Conclusions: There was a smaller decrease in the EPIC sexual function score in the CIRT group than in the RARP group. These results provide useful information for treatment decision-making of Japanese PCa patients., (© 2024. The Author(s).)

Objectives: To investigate preoperative patient factors that may predict the occurrence of perioperative complications following robot-assisted radical cystectomy at a single center in Japan., Methods: From 2013 to 2022, 103 patients underwent RARC at our institution. Complications within 90 days after surgery were assessed using the Clavien-Dindo classification. Preoperative characteristics and surgical outcomes were compared between cohorts with and without complications ≥grade 3. Logistic regression analysis was used to identify the risk factors associated with perioperative complications., Results: Overall, 27% of patients (27/103) experienced grade 3 or higher complications. The cohort that developed complications ≥grade 3 exhibited significantly higher Charlson comorbidity index (p = 0.046) and significantly lower estimated glomerular filtration rate (p = 0.048). Charlson comorbidity index ≥2 (p = 0.037) and estimated glomerular filtration rate <53 (p = 0.008) were independent predictors for the occurrence of complications ≥grade 3. The incidence of complications ≥grade 3 was 61.5% in the group possessing both factors, which was significantly higher than those in the groups possessing neither factor nor only one of the two factors., Conclusions: Our results suggest that the Charlson comorbidity index and preoperative estimated glomerular filtration rate may be predictors of perioperative complications. It is important to evaluate the patient's preoperative characteristics and choose the surgical procedure accordingly., (© 2023 The Japanese Urological Association.)

Background: Robotic pancreaticoduodenectomy (RPD) is technically demanding, and 20-50 cases are required to surpass the learning curve. This study aimed to show our experience of 76 cases from the introduction of RPD and report the changes in surgical results owing to the accumulation of cases and optimization of surgical techniques., Methods: A total of 76 patients who underwent RPD between November 2009 and May 2023 at the Fujita Health University Hospital were divided into three groups: competency (n = 23, Nov 2009-Mar 2020), proficiency (n = 31, Apr 2020-Jun 2022), and mastery (n = 22, Jul 2022-May 2023) phases. In the mastery phase, for the education of new surgeons and maintenance of surgical quality, optimization of the procedure, including hanging maneuver with or without stapling transection of the retropancreatic tissue was implemented. The surgical outcomes were compared between the groups., Results: The mean operation time decreased over time despite of the participation of newly started operators in mastery phase [competency: 921.5 min (IQR 775-996 min) vs. proficiency: 802.8 min (IQR 715-887 min) vs. mastery: 609.2 min (IQR 514-699 min), p < 0.001]. Additionally, Clavien-Dindo ≥ grade IIIa complications decreased from 52.2% in competency phase to 35.5% and 9.1% in proficiency and mastery phases, respectively (p = 0.005)., Conclusion: Operation time and major complications decreased along the learning curve from the introduction of RPD. In addition, optimization of the procedure, including hanging maneuver of the retropancreatic tissue seemed to be effective in reducing operation time and educating new RPD surgeons., (© 2024.

To investigate the incidence and risk factors of inguinal hernia (IH) after robot-assisted radical prostatectomy (RARP) using a multicentric database. The present study used a multicentric database (the MSUG94) containing data on 3,195 Japanese patients undergoing RARP between 2012 and 2021. Surgical procedures utilized for IH prevention were as follows: isolation of the vas deferens, transection of the vas deferens, isolation of the spermatic vessels, and separation of the peritoneum from the internal inguinal ring. The primary and secondary endpoints were IH-free survival and any association between post-RARP IH and clinical covariates. The prophylactic effect of the above procedures were also assessed. IH prevention was attempted in 1,465 (46.4%) patients at five of the nine hospitals. During follow-up (median 24 months), post-RARP IH developed in 243 patients. The post-RARP IH-free survival rates at years 1, 2, and 3 were 94.3%, 91.7%, and 90.5%, respectively. Old age (hazard ratio [HR] 1.037; 95% confidence interval [CI] 1.014-1.061; p = 0.001), low BMI (HR 0.904; 95% CI 0.863-0.946: p < 0.001), and low hospital volume (HR 1.385; 95% CI 1.003-1.902; p = 0.048) were independently associated with IH development. None of the procedures for IH prevention were associated with IH development. Our findings may represent the current, real-world status of post-RARP IH in Japan. The prophylactic effects of the surgical procedures for IH prevention should be further investigated in well-designed, prospective studies to optimize the surgical technique., (© 2024.

Introduction: We aimed to evaluate the safety and short-term outcomes of robotic-assisted transabdominal preperitoneal repair for inguinal hernia in 12 pioneering hospitals in Japan., Methods: Clinical data of patients who underwent robotic-assisted transabdominal preperitoneal repair between September 1, 2016, and December 31, 2021 were collected. Primary outcome measures were intra-operative adverse events and post-operative complications, whereas secondary outcomes were surgical outcomes, including chronic pain, recurrence, and learning curve., Results: In total, 307 patients were included. One case of inferior epigastric arterial injury was reported; no cases of bowel or bladder injury were reported. Thirty-five seromas were observed, including four (1.3%) cases that required aspiration. The median operative time of a unilateral case was 108 minutes (interquartile range: 89.8-125.5), and post-operative pain was rated 1 (interquartile range: 0-2) on the numerical rating scale. In complicated cases, such as recurrent inguinal hernias and robotic-assisted radical prostatectomy-associated hernias, dissection and suture were safely achieved, and no complications were observed, except for non-symptomatic seroma. All patients underwent robotic procedures, and there was no chronic post-operative inguinal pain, although one case of hernia recurrence was reported. Regarding the learning curve, plateau performance was achieved after 7-10 cases in terms of operative time (P < .001)., Conclusion: Robotic-assisted transabdominal preperitoneal repair can be safely introduced in Japan. Regardless of the involvement of many surgeons, the mastery of robotic techniques was achieved relatively quickly. The advantage of robotic technology such as wristed instruments may expand the application of minimally invasive hernia repair for complicated cases., (© 2023 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

Precision agriculture has been developed in order to achieve more productive, more profitable and environmentally sound agriculture by adjusting the input level in the site-specific manner. Therefore, the delineation of management zone in spatially variable farmland was thought to be crucial for a site-specific management of crops. Recent introduction of ICT (Information and Communication Technology) to precision agriculture however, changed the concept of management zone. Advancement in ICT enable to produce prescriptions tailored to each field by integrating soil fertility map, quasi real-time crop growth data, and weather data. In this review, at first, history of development in the assessment of the spatial variability of soil, crop growth, and yield will be mentioned. Then, the problem of inter year variability of crop yield is considered, which was caused by the interaction between soil properties and fluctuating weather. To overcome this temporal variability, integration of soil data, crop data, and weather data are indispensable, and crop models play a pivotal role in the solution. ICT includes global navigation satellite systems (GNSS), various sensors including machine vision, robotic technology, artificial intelligence, internet of things, and cloud computer which could realize the big data analysis by using data base supplied from public and private domains and raw field data from farms. High performance of cloud computer enables to derive an appropriate management zone and prescriptions. Agricultural machineries equipped with ICT devices such as GNSS, on-the-go machine visions, and sensors such as ECa, are already in market. Automatic material application equipment and automatic steering or guidance system have contributed the widespread of precision agriculture considerably. The recent advancement of precision agriculture research in Japan for paddy and upland field is reviewed as well. [ABSTRACT FROM AUTHOR]

Background: Robot-assisted rehabilitation is an appealing strategy for patients after stroke, as it generates repetitive movements in a consistent, precise, and automated manner. Objective: To identify patients who will benefit most from robotic rehabilitation for upper extremity (UE) hemiparesis. Methods:We used data from our previous randomized clinical trial comparing 6 weeks of robotic therapy (ReoGeo system) plus standard therapy (n=30) with self-guided therapy plus standard therapy (n=26) for sub-acute phase rehabilitation in adults with mild to moderate UE hemiparesis. The outcome measures were three Fugl-Meyer (FMA) motor scores: total UE score, proximal UE score, and UE flexor synergy score. Based on pre-therapy UE flexor synergy scores, participants were categorized into mild (10–12 points), moderate (6–9 points), and severe (0–5 points) impairment classes. Results: In the robotic group, all outcome measures improved after therapy in patients with moderate or severe impairment. In the self-guided therapy, most outcomes did not improve, regardless of the impairment class. When changes from pre- to post-therapy were compared between robotic and self-guided groups, most outcomes were similar in all impairment classes. However, robotic therapy was associated with greater improvement in UE flexor synergy than self-guided therapy in patients with moderate impairment (2.3±1.3 vs. -0.1±2.8, P=0.027). Conclusions: Post-strokerobot-assisted rehabilitation, as an adjunct to standard rehabilitation therapy, improved UE function in patients with moderate or severe pre-therapy UE flexor synergy impairment. Adjunct robotic therapy produced greater improvement in UE flexor synergy motor function than adjunct self-guided rehabilitation in patients with moderate pre-therapy impairment.

Robotic gastrectomy (RG) using the da Vinci Surgical System for gastric cancer was approved for national medical insurance coverage in Japan in April, 2018, and has been used increasingly since. We reviewed the current evidence on RG, open gastrectomy (OG), and conventional laparoscopic gastrectomy (LG) to identify differences in surgical outcomes between Japan and other countries. Briefly, three independent reviewers systematically reviewed the data collected from a comprehensive literature search by an independent organization and focused on the following nine endpoints: mortality, morbidity, operative time, estimated volume of blood loss, length of postoperative hospital stay, long-term oncologic outcome, quality of life, learning curve, and cost. Overall, the mortality rate of the three approaches did not differ, but RG and LG had less intraoperative blood loss and resulted in a shorter postoperative hospital stay than OG. RG had longer operative times and incurred higher costs than LG and OG. However, in Japan, RG may be more effective than LG and OG for decreasing morbidity. Further studies are needed to establish the specific indications for RG, optimal robotic setup, and dissection methods to best utilize the surgical robot. [ABSTRACT FROM AUTHOR]

Background: Our group developed a rehabilitation robot to assist with repetitive, active reaching movement of a paretic upper extremity. The robot is equipped with a servo motor-controlled arm-weight support and works in conjunction with neuromuscular electrical stimulation and vibratory stimulation to facilitate agonist-muscle contraction. In this before-and-after pilot study, we assessed the feasibility of applying the robot to improve motor control and function of the hemiparetic upper extremity in patients who suffered chronic stroke.Methods: We enrolled 6 patients with chronic stroke and hemiparesis who, while sitting and without assistance, could reach 10 cm both sagitally and vertically (from a starting position located 10 cm forward from the patient's navel level) with the affected upper extremity. The patients were assigned to receive reaching exercise intervention with the robot (Yaskawa Electric Co., Ltd. Fukuoka, Japan) for 2 weeks at 15 min/day in addition to regular occupational therapy for 40 min/day. Outcomes assessed before and after 2 weeks of intervention included the upper extremity component of the Fugl-Meyer Assessment (UE-FMA), the Action Research Arm Test (ARAT), and, during reaching movement, kinematic analysis.Results: None of the patients experienced adverse events. The mean score of UE-FMA increased from 44.8 [SD 14.4] to 48.0 [SD 14.4] (p = 0.026, r = 0.91), and both the shoulder-elbow and wrist-hand scores increased after 2-week intervention. An increase was also observed in ARAT score, from mean 29.8 [SD 16.3] to 36.2 [SD 18.1] (p = 0.042, r = 0.83). Kinematic analysis during the reaching movement revealed a significant increase in active range of motion (AROM) at the elbow, and movement time tended to decrease. Furthermore, trajectory length for the wrist ("hand path") and the acromion ("trunk compensatory movement") showed a decreasing trend.Conclusions: This robot-assisted modality is feasible and our preliminary findings suggest it improved motor control and motor function of the hemiparetic upper extremity in patients with chronic stroke. Training with this robot might induce greater AROM for the elbow and decrease compensatory trunk movement, thus contributing to movement efficacy and efficiency.

Aim: The primary aim of this study was to examine the impact of age, gender and the stage of dementia on the results of an assistive technology intervention that make use of communication robots (com‐robots). The intervention was designed to improve the social participation and interactions of nursing home residents. While our previous study showed that the overall effects of com‐robot intervention were positive, it was unknown what impact age, gender and the stage of dementia of participants had on such an intervention. Methods: This was a non‐randomized, multicenter quasi‐experimental intervention study conducted in residential care homes in Japan. Two types of com‐robots were introduced for 8 weeks after baseline evaluation. The World Health Organization's ICF was used for evaluating any changes present after the 8‐week intervention. In total, 78 residents (68 women, 10 men, 86.5 ± 7.7 years old) participated in the study. The Degree of Daily Life Independence Score for People with Dementia (DDLIS‐PD) was employed for measuring the stage of dementia. Results: The results showed that the older participants aged ≥80 benefited more from the intervention than the younger cohort did (P < 0.05). A greater improvement was shown among those with a more advanced stage of dementia than those at a less advanced stage (P < 0.05), when using DDLIS‐PD. Conclusions: The overall findings support the use of com‐robots within the context of a care team for older people with moderate dementia, and those who are aged ≥80 years.

When Buddhism fails to live up to the projected promise of its doctrine or past forms, it is often the human nature of its adherents ("Bad Buddhists"), rather than the content of its teachings ("Bad Buddhism"), that is blamed. But what if such human failings--greed, corruption, violence, even mortality--could be transcended? In the quest for a "good Buddhism," high-tech designs that utilise robotics, artificial intelligence, algorithmic agency, and other advancements are increasingly pursued as solutions by innovators inside and outside Buddhist communities. In this paper, we interrogate two recent cases of what we call "Buddhist techno-salvationism." Firstly, Pepper, the semi-humanoid robot who performs funeral sutras to a rapidly secularising and aging population of parishioners in Japan. Secondly, the Lotos Network, a US start-up proposing to use blockchain technology to combat financial corruption within global sangha. We argue that such robotic and digital experiments are the logical outcome of techno-salvationist discourses that identify human failings as the principal barrier to perfect Buddhist praxis. If not always practical solutions, these interventions are powerful nonetheless as contested projections of Buddhist futures. [ABSTRACT FROM AUTHOR]

Construction of infrastructures, such as bridges and tunnels, has increased significantly in Japan in the past 50 years. Most of the civil infrastructure is now aging rapidly. Basic infrastructure maintenance and management require proper repairing and reinforcement, for which periodic inspections are indispensable. Inspection of civil infrastructure, however, requires a large amount of workforce for traffic regulation and accessing difficult-to-reach locations. Occupational safety is also an important issue that cannot be ignored. Furthermore, technologies related to emergency responses after the occurrence of natural disasters are important, especially with the increasing number of natural disasters recently. Executing a safe and quick disaster response action is very challenging. To meet the above problems, "Infrastructure Maintenance, Renovation and Management" was established in the Cross-ministerial Strategic Innovation Promotion Program (SIP). Research and development programs for infrastructure management systems using new technologies had been conducted since 2014. In this paper, the research and development programs related to robotic technologies are described. Specifically, robotic technologies for bridge inspection, tunnel inspection, and disaster responses are introduced. In addition, the scheme of the SIP regional bases that facilitates the availability of the developed technologies to local governments is also introduced. [ABSTRACT FROM AUTHOR]

Objectives: Recently, use of the Hybrid Assistive Limb (HAL) that is effective for improvement of gait ability in chronic stroke patients has been reported. However, how long the effects are maintained remains unknown. The purpose of the present study was to investigate whether the effect of gait training using the HAL on gait ability was maintained for 3 months after the intervention. Methods: A longitudinal, observational study with an intervention for a single group that adhered to the STROBE guidelines was performed. Nine chronic stroke patients were enrolled in this study. The patients performed gait training sessions using the HAL, 2–5 sessions/week for 3 weeks. Gait speed, stride length, cadence, and 2-minute walk distance (2MWD) were measured before and after intervention and at 3-month follow-up. The clinical trial registration number of this study is UMIN000012764 R000014756. Results: Compared to the initial status, gait speed (p =.02), stride length (p =.03), cadence (p =.01), and 2MWD (p <.05) were significantly increased immediately after the intervention. Moreover, gait speed (p <.01), cadence (p =.03), and 2MWD (p =.02) remained significantly higher 3 months after the intervention. There were no significant changes in all outcome measures between after intervention and at 3-month follow-up. Conclusions: This study showed that gait training using the HAL resulted in significant improvement of gait ability after the intervention and the effect was maintained for 3 months after the training.

The article focuses on the COVID-19 pandemic and organizational resilience as unanticipated outcome of introducing socially assistive robots in nursing homes. Topics discussed include the robots were introduced alongside a bedside infrared camera, which, in case of emergencies such as falls; and the 24-week-long, pre-post, quasi-experimental multicenter study in six nursing homes indicated improvements in residents' targeted activities and participation.

Purpose: We created a clinically applicable nomogram to predict locally advanced prostate cancer using preoperative parameters and performed external validation using an external independent validation cohort., Patients and Methods: From a retrospective multicenter cohort study of 3622 Japanese patients with prostate cancer who underwent robot-assisted radical prostatectomy at ten institutions, the patients were divided into two groups (MSUG cohort and validation cohort). Locally advanced prostate cancer was defined as pathological T stage ≥ 3a. A multivariable logistic regression model was used to identify factors strongly associated with locally advanced prostate cancer. Bootstrap area under the curve was calculated to assess the internal validity of the prediction model. A nomogram was created as a practical application of the prediction model, and a web application was released to predict the probability of locally advanced prostate cancer., Results: A total of 2530 and 427 patients in the MSUG and validation cohorts, respectively, met the criteria for this study. On multivariable analysis, initial prostate-specific antigen, prostate volume, number of cancer-positive and cancer-negative biopsy cores, biopsy grade group, and clinical T stage were independent predictors of locally advanced prostate cancer. The nomogram predicting locally advanced prostate cancer was demonstrated (area under the curve 0.72). Using a nomogram cutoff of 0.26, 464 of 1162 patients (39.9%) could be correctly diagnosed with pT3, and 2311 of 2524 patients (91.6%) could avoid underdiagnosis., Conclusions: We developed a clinically applicable nomogram with external validation to predict the probability of locally advanced prostate cancer in patients undergoing robot-assisted radical prostatectomy., (© 2023.

Background/aim: Technological solutions can support the elderly, improve their quality of life and reduce isolation and loneliness. The Euro-Japan ACCRA (Agile Co-Creation for Robots and Aging) project has the objective of building a reference co-creation methodology for the development of robotic solutions for ageing. The aim of this study is to provide a pilot qualitative analysis of the real needs of elderly people and their caregivers when exposed to conversational activities with robots and to identify priority needs that should be developed from end-user perspectives. Methods: A qualitative research design was adopted to define a pre-structured questionnaire that was administered to the elderly taking part in the piloting sessions. Three groups of end-users were included: subjects with an age ≥ 60 years, informal caregivers and formal caregivers. Results: The interviews were carried out in Italy and Japan. A total of 17 elderly and 36 caregivers were recruited. Common needs in the two sites were categorized into 3 groups: Communication; Emotion Detection and Safety. General robot acceptance level is good and perception is positive among participants in the pilot sites. Conclusion: A positive perception of the elderly on the application of a robotic solution was found and many are the needs that could be addressed by an appropriate and careful robotic development taking into account the real needs and capabilities of the involved subjects.

This paper presents several multi-modal 3D datasets for the problem of categorization of places. In this problem. a robotic agent should decide on the type of place/environment where it is located (residential area, forest, etc.) using information gathered by its sensors. In addition to the 3D depth information, the datasets include additional modalities such as RGB or reflectance images. The observations were taken in different indoor and outdoor environments in Fukuoka city, Japan. Outdoor place categories include forests, urban areas, indoor parking, outdoor parking, coastal areas, and residential areas. Indoor place categories include corridors, offices, study rooms, kitchens, laboratories, and toilets. The datasets are available to download at http://robotics.ait.kyushu-u.ac.jp/kyushu_datasets.

Background and Objectives Recent years have seen social robotic pets introduced as a means of treating behavioral and psychological symptoms of dementia, and many show promising potential. In this study, we sought to explore family members' perceptions of the Japanese-developed baby harp seal, Paro (version 9), and a look-alike, nonrobotic Plush Toy, when used by their relative with dementia for 15 min, 3 afternoons per week for 10 weeks. Research Design and Method The study employed a descriptive qualitative approach, which was nested within a larger cluster randomized controlled trial. A convenience sample of 20 family members (n = 10 each from the Paro and Plush Toy conditions) with relatives in 9 long-term care facilities in Queensland, Australia, completed individual semi-structured interviews (telephone or face-to-face). Inductive, data-driven thematic analysis of the data was undertaken with the assistance of the qualitative management software, ATLAS.ti®. Results Family members of long-term care residents with dementia expressed positive perceptions of the Paro, perceiving that it improved mood, reduced agitation, and provided opportunity for communication for their relative. Negative perceptions of the Plush Toy were given by family members, primarily because of its lack of movement and engagement. Conclusion Family members were keen for their older relative with dementia to use a social robot that moved and engaged with them, and Plush Toys that were static and unresponsive were perceived as being unimportant in improving quality of life. However, the current cost of Paro was identified by family members as a major limitation to use. [ABSTRACT FROM AUTHOR]

Purpose: The aim of the study was to analyze and compare elderly care personnel attitudes toward care robots in Finland and Japan. Design: Cross‐sectional survey in Finland and Japan. Methods: The Finnish sample was collected from care personnel in home care facilities in five municipalities in 2016. The Japanese sample was collected from personnel in two rehabilitative day centers and three residential care homes for the elderly in the north of Honshu Island in 2017. The data were analyzed using basic statistical methods and calculated descriptive statistics (frequencies). Differences between the Finnish and Japanese data have been analyzed using the Mann‐Whitney U test. Findings: Overall, Japanese care personnel assessed the usefulness of robots more positively than did their Finnish counterparts. The data showed substantial national differences in the perceived importance of various potential tasks for care robots. The findings show that there are also certain fears related to the introduction of care robots, in particular among the Finnish care personnel. Discussion: The data from the Japanese care personnel bring new perspectives to the concept of a close human–robot relationship. The differences seen in the results between Finland and Japan can be partly explained by cultural dissimilarity, but it is also known that Japan is a more developed country with regard to the use of robotics in nursing care. The research highlights the importance of cultural factors when examining the issue of care robotics. The factors affecting fear are a concern that care robots would be used to replace people, the dehumanization of treatment, and an increased loneliness in the elderly. Thus, further research is required to demonstrate the relationship between different cultural factors, and attitudes and conceptions toward care robots. Clinical Relevance: Management plays a key role when implementing robotics. It is important to help care personnel accept care robots, and to diminish any fears that their introduction would make the treatment of elderly people inhumane or in some way add to their loneliness. As such, education is crucial in changing attitudes and making care personnel understand that care robots can perform routine tasks, allowing care personnel to focus on providing improved care and nursing.

Background: We conducted a retrospective study to compare the perioperative course and lymph node (LN) counts of patients undergoing limited pelvic lymphadenectomy (lPLND) or extended pelvic lymphadenectomy (ePLND) during robot-assisted radical prostatectomy in an initial Japanese series.Methods: The cohort included 1333 patients who underwent either lPLND (n = 902) or ePLND (n = 431) during robot-assisted radical prostatectomy at five institutions in Japan. All complications within 28 days of surgery were recorded, and clinical data were collected retrospectively. The outcomes and complications were compared relative to the extent of lymphadenectomy, and we conducted univariate and multivariate logistic regression analyses to assess the predictors of the major complications.Results: On multivariate analysis for evaluating the associations between major complications and perioperative characteristics, console time (p = 0.001) was significantly associated with major complications, although the extent of lymphadenectomy (p = 0.272) was not significantly associated with major complications. In the distribution of positive LNs removed in the extended pelvic lymphadenectomy cohort, 60.4% of patients had positive LNs only in the obturator/internal iliac region. However, 22.6% of the patients with positive LNs had no positive LNs in the obturator/internal iliac region, but only in the external/common iliac region.Conclusions: ePLND, which significantly increased the console time and blood loss but nearly quadrupled the lymph node yield, is considered a relatively safe and acceptable procedure. Moreover, the results of this study suggest that ePLND improves staging and removes a greater number of metastatic nodes. [ABSTRACT FROM AUTHOR]

Abstract: This study investigated the responses of 4‐ and 5‐year‐old Japanese children to yes‐no questions about familiar and unfamiliar objects that were asked by a communicative or a non‐communicative humanoid robot. The children in the communicative condition watched a pretrial video in which a humanoid robot interacted with a human adult, and those in the non‐communicative condition watched a pretrial video in which the same humanoid robot was unresponsive to the same human adult's utterances and actions. Then, all the children watched a video in which the robot asked 24 yes‐no questions. The results indicated that 4‐ and 5‐year‐olds in the two conditions showed similar response tendencies, with no age differences. Further, the children showed no response biases to familiar objects and nay‐saying bias to unfamiliar objects. Children's perception of robots is discussed. Highlights: We investigated whether 4‐ to 5‐year‐olds answer humanoid robot's yes‐no questions. The children were asked yes‐no questions by either a communicative and non‐communicative humanoid robot. Children in both age groups in two conditions showed similar response tendencies to humanoid robot: They may have expectation for humanoid robots that they are communicative partner.

This study focuses on cultural differences in perceptions of comfortableness with robots that have either positive or negative anthropomorphic features. To clarify the effect of the valence of anthropomorphic features in addition to the effect of the number of features in different countries, this study investigated how Americans and Japanese perceive comfortableness with a positively or negatively featured robot. A total of 360 respondents (180 Americans and 180 Japanese) read a cover story about one robot. In the story, the valence and numbers of anthropomorphic features of the robot were manipulated and the respondents completed the comfortableness measurements including Comfort, Controllability and so on. The results demonstrated that Americans perceived more Comfort, Controllability, and Performance than did the Japanese respondents. The Americans show different levels of comfortableness perceptions in response to large number of features, and the Japanese respondents showed different levels of comfortableness in response to small number of features. We discuss the cultural background for the different patterns of perceived comfortableness between U.S. and Japan. [ABSTRACT FROM AUTHOR]

BACKGROUND: The robotic Hybrid Assistive Limb (HAL) provides motion according to the wearer's voluntary activity. HAL training effects on walking speed and capacity have not been clarified in subacute stroke. OBJECTIVES: To determine improvement in walking ability by HAL and the most effective improvement measure for use in future large-scale trials. METHODS: Sixteen first-ever hemiplegic stroke patients completed at least 20 sessions over 5 weeks. Per session, the experimental group received no more than 20 min of gait training with HAL (HT) and 40 min of conventional physiotherapy, whereas the control group received at least 60 min of conventional physiotherapy. Primary outcome was maximum walking speed (MWS). RESULTS: The change in MWS from baseline at week 5 was 11.6±10.6 m/min (HAL group) and 2.2±4.1 m/min (control group) (adjusted mean difference = 9.24 m/min, 95% confidence interval 0.48-18.01, P = 0.040). In HAL subjects there were significant increases in Self-selected walking speed (SWS; a secondary outcome) and in step length (a secondary outcome) at MWS and SWS compared with controls. CONCLUSIONS: HT improved walking speed in hemiplegic sub-acute stroke patients. In future, randomized controlled trials are needed to confirm the utility of HT. [ABSTRACT FROM AUTHOR]

Background: Robot-assisted valve surgery represents the latest development in the field of minimally invasive approaches. Robotic assistance may provide greater visualization, enhanced dexterity, and greater precision than traditional mini-thoracotomy aortic valve replacement., Methods and results: Aortic valve replacement operations using the da Vinci Xi Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA) were performed on 2 patients, 1 with severe aortic insufficiency and the other with aortic stenosis. Both patients had an uneventful postoperative course and were discharged without any adverse events., Conclusions: Robot-assisted assisted aortic valve replacement appears feasible and safe in limited cases.

Every research participant has their own personality characteristics. For example, older adults assisted by socially assistive robots (SAR) may have their own unique characteristics and may not be representative of the general population of older adults. In this research, we compared the average personality characteristics of participants in a workshop on robotics recruited directly through posting with those of older Japanese adults to examine participant selection bias and group representativeness for future study of SARs. After a one-week recruitment period, the workshop was attended by 20 older participants (nine males and 11 females) aged between 62 and 86 years. Extroversion among workshop participants was 4.38, 0.40 higher than the average for older adults in Japan. The workshop participants' openness was 4.55, 1.09 higher than the average for the Japanese elderly. Thus, the results indicate a slight selection bias in the personal characteristics of the participants depending on the recruitment method when compared to the Japan national average for older adults. In addition, only one of 20 participants was below the cutoff on the LSNS-6 score and considered to have a tendency toward social isolation. The development and introduction of socially assistive robots is often being considered to support people in social isolation in their daily lives; however, the results of this study showed that it is difficult to recruit people who tend to be socially isolated when gathering research participants by methods such as posting. Therefore, the effectiveness of the method of recruiting participants should be carefully verified in research regarding socially assistive robots., Competing Interests: The authors declare no conflict of interest.
