An important recent trend in education has been the integration of different technologies such as digital games, online courses, and educational robots. The development of educational robots such as lego Mindstorms nxt allows students to learn to build their own robots. This paper describes the human-robot interaction (hri) focusing especially on the model lego Mindstorms nxt. A questionnaire among 250 Syrian school and university students was conducted to investigate the different perceptions about lego robots in 2016. The informants were grouped based on their age; participants in the first group were aged between 11 and 18 years while participants in the second between 19 and 24. The current study also focuses on the factors leading to the acceptance of lego robots. Another questionnaire was conducted to highlight what factors determine the degree of acceptance of lego robots by the studied groups. Significant age and gender effects were found. The results show a noticeable difference between the two age groups, with the younger group tending to accept lego robots more. Furthermore, it was found that male respondents show more positive reactions towards lego robots than females.

The present study examined the effect of warning labels in alcohol advertising on the perception of risk for alcohol consumption. Under incidental conditions, subjects from two age groups, young (M = 13.6 years) and older (M = 23.3 years), examined a collection of magazine ads. Three of the ads in the booklet were for alcoholic beverages and these were either accompanied by a warning or the warning was absent. When present, the warnings were manipulated by the orthogonal combination of text voice (2nd vs. 3rd person) and pictorial (presence vs. absence) in a between-subjects design. A fifth condition served as the no-warning control. After examining the magazine ads, subjects answered a questionnaire which assessed several dimensions related to the ads: number and type of ads, attractiveness of the ads, and number and type of warnings in the ads. Examination of the questions dealing with the risk of alcohol consumption indicated that adolescents rated their own risk lower than the risk to adolescents in general, but that this bias in risk ratings was not evident when warnings were present. There were also several other age and gender effects. While no individual warning manipulation was found to be consistently superior to another, the results suggest that warnings can be effective in producing proper estimations of risk in different age populations.

Abstract Objective The aim of this study is to measure the average corpus callosum (CC) volume of healthy Turkish humans and to analyze the effects of gender and age on volumes, including the genu, truncus, and splenium parts of the CC. Patients and Methods Magnetic resonance imaging brain scans were obtained from 301 healthy male and female subjects, aged 11 to 84 years. The median age was 42 years (min–max: 11–82) in females and 49 years (min–max: 12–84) in males. Corpus callosum and its parts were calculated by using MRICloud. CC volumes of each subject were compared with those of the age and gender groups. Results All volumes of the CC were significantly higher in males than females. All left volumes except BCC were significantly higher than the right volumes in both males and females. The oldest two age groups (50–69 and 70–84 years) were found to have higher bilateral CC volumes, and bilateral BCC volumes were also higher than in the other two age groups (11–29 and 30–49 years). Conclusion The results suggest that compared with females/males, females have a faster decline in the volume of all volumes of the CC. We think that quantitative structural magnetic resonance data of the brain is vital in understanding human brain function and development.

The influence of age and gender on the pharmacokinetics of levofloxacin in healthy subjects receiving a single oral 500-mg dose of levofloxacin was investigated in this parallel design study. Six young males (aged 18 to 40 years), six elderly males (aged > or = 65 years), six young females (aged 18 to 40 years), and six elderly females (aged > or = 65 years) were enrolled and completed the study. The study reveals that the bioavailability (rate and extent) of levofloxacin was not affected by either age or gender. In both age (young and elderly) and gender (male and female) groups of subjects, peak concentrations in plasma were reached at approximately 1.5 h after dosing; renal clearance of levofloxacin accounted for approximately 77% of total body clearance, and approximately 76% of the administered dose was recovered unchanged in urine over the 36 h of collection. The apparent differences in the calculated pharmacokinetic parameters for levofloxacin between the age groups (young versus elderly) and between the gender groups (males versus females) could be explained by differences in renal function among the subjects. A single dose of 500 mg of levofloxacin administered orally to both young and old, male and female healthy subjects was found to be safe and well tolerated. As the differences in levofloxacin kinetics between the young and the elderly or the males and the females are limited and are mainly related to the renal function of the subjects, dose adjustment based on age or gender alone is not necessary.

Abstract This paper focuses on the Iranian taaroff politeness system. We report a quantitative analysis of the attitudes to taaroff held by 60 Iranians (30 women and 30 men) of two age groups (20–29 and 40–59 years old) and their use of formulaic taaroff expressions in conversations. The data come from dialogues elicited from the participants in Iran via short scripted scenarios and from their answers to a questionnaire survey about their attitudes to taaroff. Taaroff expressions were manually extracted from the dialogue transcripts and their overall use as well as frequencies of each expression were compared across the gender and age groups with the help of t-tests. The participants’ answers to the survey questions were compared across the groups with Kruskal-Wallis H tests. The results show statistically significant differences in the participants’ attitudes to taaroff and in its use in dialogues by gender and age group.

Estimating distances between people and robots plays a crucial role in understanding social Human–Robot Interaction (HRI) from an egocentric view. It is a key step if robots should engage in social interactions, and to collaborate with people as part of human–robot teams. For distance estimation between a person and a robot, different sensors can be employed, and the number of challenges to be addressed by the distance estimation methods rise with the simplicity of the technology of a sensor. In the case of estimating distances using individual images from a single camera in a egocentric position, it is often required that individuals in the scene are facing the camera, do not occlude each other, and are fairly visible so specific facial or body features can be identified. In this paper, we propose a novel method for estimating distances between a robot and people using single images from a single egocentric camera. The method is based on previously proven 2D pose estimation, which allows partial occlusions, cluttered background, and relatively low resolution. The method estimates distance with respect to the camera based on the Euclidean distance between ear and torso of people in the image plane. Ear and torso characteristic points has been selected based on their relatively high visibility regardless of a person orientation and a certain degree of uniformity with regard to the age and gender. Experimental validation demonstrates effectiveness of the proposed method.

Test Retest Reliability

Most measures of auditory sensitivity at extended high frequencies (frequencies greater than 8 kHz) have been obtained from listeners with normal hearing less than 40 years of age. The purpose of this study was (a) to measure thresholds at frequencies above 8 kHz in older listeners who, as a group, have elevated thresholds at lower frequencies, and (b) to assess test-retest reliability, age and gender effects, and the influence of thresholds below 8 kHz. Extended high-frequency (EHF) thresholds were measured for 162 older listeners (60–79 years) using a commercially available high-frequency audiometer, with a frequency range of 8 to 18 kHz and an intensity range of 0 to 110 dB SPL. Thresholds were measured once at the beginning of a 1- to 2-hour test session and then remeasured at the end of the test session. EHF thresholds of older listeners with normal hearing at conventional audiometric frequencies were substantially higher than the thresholds reported for younger listeners with normal hearing by Dreschler and van der Hulst (1987). EHF thresholds of older listeners with hearing loss at conventional audiometric frequencies were further elevated as compared to older listeners with normal hearing. Differences in EHF thresholds between females and males were either not present or were reduced when gender differences in conventional audiometric thresholds were taken into account. No significant differences were seen in thresholds at 8 kHz and higher between the 60- to 69- and 70- to 79-year-old age groups. Results also indicated that thresholds above 8 kHz can be measured in older listeners within a clinically acceptable ±10 dB test-retest range.

At present, sexual robots have become a new paradigm of social robots. In this paper, we developed a systematic literature review about sexual robots (sexbots). To do this, we used the Scopus and WoS databases to answer different research questions regarding the design, interaction, and gender and ethical approaches from 1980 until 2020. In our review, we found a male bias in this discipline, and in recent years, articles have shown that user opinion has become more relevant. Some insights and recommendations on gender and ethics in designing sexual robots were also made.
