This article presents a system for soft human–robot handshaking, using a soft robot hand in conjunction with a lightweight and impedance-controlled robot arm. Using this system, we study how different factors influence the perceived naturalness, and give the robot different personality traits. Capitalizing on recent findings regarding handshake grasp force regulation, and on studies of the impedance control of the human arm, we investigate the role of arm stiffness as well as the kinesthetic synchronization of human and robot arm motions during the handshake. The system is implemented using a lightweight anthropomorphic arm, with a Pisa/IIT Softhand wearing a sensorized silicone glove as the end-effector. The robotic arm is impedance-controlled, and its stiffness changes according to different laws under investigation. An internal observer is employed to synchronize the human and robot arm motions. Thus, we simulate both active and passive behavior of the robotic arm during the interaction. Using the system, studies are conducted where 20 participants are asked to interact with the robot, and then rate the perceived quality of the interaction using Likert scales. Our results show that the control of the robotic arm kinesthetic behavior does have an effect on the interaction with the robot, in term of its perceived personality traits, responsiveness, and human-likeness. Our results pave the way towards robotic systems that are capable of performing human–robot interactions in a more human-like manner, and with personality.

Self–ratings of health (SRH) are widely used in large surveys and have been shown to predict mortality over and above more objective health measures. However, the debate still continues about what SRH actually represents and what the processes underlying people's assessments of their health are. The main aim of this study is to examine the role of the Five–Factor Model personality traits in general SRH assessment while controlling for the effects of objective health indicators, health–related quality of life and subjective well–being in a large population–based dataset of Estonian adults. A hierarchical linear regression analysis showed that only self–rated, but not informant–rated, neuroticism explained additional variance in SRH when the other aforementioned variables were taken into account. Our findings indicate that people's general SRH is a relatively good reflection of their objectively measured health status, but also that the way in which people experience and evaluate the quality of their lives—both in terms of subjective well–being and more specific aspects of health—plays a significant role in general SRH assessments.

Abstract:  Tehnlogical advances to date have grown increasingly sophisticated technolgy, especially in robotic technogy which is currently developed to achieve work result that are make human work easier welding process with manual systems need to be switched to automatic systems. The mechanical concept of the arm that will be applied to Automatic Welding Carrier Machine by applying the mechanical concept of a 3D machine which is expected to increase mobility, working range of the tool as well as increasing the quality of automatic welding results. In this research, the method used is experimental research methods and simulations that aim to know the results of the analysis on the mechanics of the robot arm. The data generated after performing calculations with provide a load on the leadscrew of  the compressive stress that occurs i the leadscrew is , the voltage bending is  and the shear stress that occurs is , so that  the lead crew is said to be able to encourge maximum allowable amount of . The torque required by the motor drive to push the received load on the Z ( ) axis is equal to , then the selection of the nema23 stepper motor is stated very capable as a robotic arm mover because have torque . With the loading of the 2020 profile arm rod at  using ansys simulation, the maximum total deformation that may occur is , so that the 2020 profile rod can be said to be safe for use on Automatic Welding Carrier Machine.

Personality traits of older adults and their contribution to life satisfaction and generative interest were assessed. A total of 342 older participants (66% women), mean age = 67.89 years old ( SD = 6.52, range = 55–84 years old), who attended the University of the Experience in Salamanca (Spain), were evaluated. Information on sociodemographic data, perceived health and activity, personality traits, generativity, and life satisfaction was collected using self-reported questionnaires. Results confirmed a relation between personality traits, life satisfaction, and generativity. In addition, generative concern, neuroticism, extraversion, agreeableness, and conscientiousness predicted life satisfaction at this stage. Moreover, the role of personality on generativity was confirmed. Individuals with interest and agreeableness toward others, who are organized, persistent, and motivated, are more predisposed to generativity. These results open the way to develop intervention programs that enhance positive personality traits and generative interest to improve quality of life of older people.

ABSTRACTBackground:Personality may predispose family caregivers to experience caregiving differently in similar situations and influence the outcomes of caregiving. A limited body of research has examined the role of some personality traits for health-related quality of life (HRQoL) among family caregivers of persons with dementia (PWD) in relation to burden and depression.Methods:Data from a large clinic-based national study in South Korea, the Caregivers of Alzheimer's Disease Research (CARE), were analyzed (N = 476). Path analysis was performed to explore the association between family caregivers’ personality traits and HRQoL. With depression and burden as mediating factors, direct and indirect associations between five personality traits and HRQoL of family caregivers were examined.Results:Results demonstrated the mediating role of caregiver burden and depression in linking two personality traits (neuroticism and extraversion) and HRQoL. Neuroticism and extraversion directly and indirectly influenced the mental HRQoL of caregivers. Neuroticism and extraversion only indirectly influenced their physical HRQoL. Neuroticism increased the caregiver's depression, whereas extraversion decreased it. Neuroticism only was mediated by burden to influence depression and mental and physical HRQoL.Conclusions:Personality traits can influence caregiving outcomes and be viewed as an individual resource of the caregiver. A family caregiver's personality characteristics need to be assessed for tailoring support programs to get the optimal benefits from caregiver interventions.

Background: The quality of sibling relationships is an important factor in the development of individuals, particularly in the context of a relationship with a brother or sister with disabilities. Aims: This research aims to assess the moderating role of the quality of the relationship with siblings between personality traits and coping strategies. Methods: The participants were 187 adults, of whom 97(51.9%) were Individuals with brothers or sisters with intellectual disabilities (S-IDs), aged 18 to 60 years (M=30.22; SD=12.17). The second group was 90 (48.1%) Individuals with typical developmental siblings (S-TDs) aged 18 to 76 years (M=28.56; SD=11.66). Respondents completed the Big Five Questionnaire (BFQ), the Coping Orientation to Problem Experiences (COPE), and the Adult Sibling Relationships Questionnaire (ASRQ). Results: The data show a correlation between personality traits and coping strategies. In addition, the size of the ASRQ was found to moderate the relationship between personality traits and coping strategies, albeit in a different way between the two groups. Conclusion: The quality of the reality with brothers or sisters turns out to be an important factor in the development, and it is found to mediate the relationship between personality traits and the development of coping strategies, both in S-TDs and S-IDs, presenting similarities and differences. Future research guidelines have been discussed.
