Background According to the US Bureau of Labor Statistics, nurses will be the largest labor pool in the United States by 2022, and more than 1.1 million nursing positions have to be filled by then in order to avoid a nursing shortage. In addition, the incidence rate of musculoskeletal disorders in nurses is above average in comparison with other occupations. Robot-assisted health care has the potential to alleviate the nursing shortage by automating mundane and routine nursing tasks. Furthermore, robots in health care environments may assist with safe patient mobility and handling and may thereby reduce the likelihood of musculoskeletal disorders. Objective This pilot study investigates the perceived ease of use and perceived usefulness (acceptability) of a customized service robot as determined by nursing students (as proxies for nursing staff in health care environments). This service robot, referred to as the Adaptive Robotic Nurse Assistant (ARNA), was developed to enhance the productivity of nurses through cooperation during physical tasks (eg, patient walking, item fetching, object delivery) as well as nonphysical tasks (eg, patient observation and feedback). This pilot study evaluated the acceptability of ARNA to provide ambulatory assistance to patients. Methods We conducted a trial with 24 participants to collect data and address the following research question: Is the use of ARNA as an ambulatory assistive device for patients acceptable to nurses? The experiments were conducted in a simulated hospital environment. Nursing students (as proxies for nursing staff) were grouped in dyads, with one participant serving as a nurse and the other acting as a patient. Two questionnaires were developed and administrated to the participants based on the Technology Acceptance Model with respect to the two subscales of perceived usefulness and perceived ease of use metrics. In order to evaluate the internal consistency/reliability of the questionnaires, we calculated Cronbach alpha coefficients. Furthermore, statistical analyses were conducted to evaluate the relation of each variable in the questionnaires with the overall perceived usefulness and perceived ease of use metrics. Results Both Cronbach alpha values were acceptably high (.93 and .82 for perceived usefulness and perceived ease of use questionnaires, respectively), indicating high internal consistency of the questionnaires. The correlation between the variables and the overall perceived usefulness and perceived ease of use metrics was moderate. The average perceived usefulness and perceived ease of use metrics among the participants were 4.13 and 5.42, respectively, out of possible score of 7, indicating a higher-than-average acceptability of this service robot. Conclusions The results served to identify factors that could affect nurses’ acceptance of ARNA and aspects needing improvement (eg, flexibility, ease of operation, and autonomy level).

The study investigated the risk behaviours on road traffic accident among commercial vehicle drivers in Jalingo Metropolitan, Taraba State. The descriptive survey research design was adopted for the study. The population was 2,000 commercial vehicle drivers registered with National Union of Road Transport Workers (NURTW) proportional sampling technique was used to sample 160 commercial vehicle drivers. Out of 160 copies of the questionnaire administered, 148 copies of questionnaires were returned for data analysis. The null hypotheses were tested at 0.05 level of significance. Therefore, the study recommend that Government and other relevant agencies such as National Road Safety Corps, vehicle inspection officers (VIO) should organize periodic workshop/ enlightenment programme in order to educate commercial vehicle drivers on the behaviours that predispose them to road accidents. Also commercial vehicle park owners should not only employ qualified drivers, but as well ensure that their drivers do not indulge in risky behaviour that are capable of causing road accident. Finally commercial vehicle drivers caught engaging in risk behaviour while on duty should be severely punished in order to deter others from the acts.
