Abstract A passive aligning strategy for the assembly task of a ribbon cable is presented using a sliding surface gripper. Once the gripper grasps the ribbon cable, the sliding surface of the gripper pulls the cable in one direction, and at the end of the pulling process, the box-shaped structure of the fingertip of the gripper passively aligns the cable to a predictable pose. The relationship between the alignment speed of the cable on the sliding surface and the grasping force was modeled and verified by experiments. The maximum position error of the ribbon cable connector aligned by the proposed method was 0.7 mm, which was smaller than the mating tolerance between typical male-and-female connectors. The mating of the connectors was successfully conducted with an industrial robot (ABB IRB120) whose repeatability is less than a millimeter. The entire assembly process of ribbon cable connectors, including visual recognition of the ribbon cable pose, grasping and aligning of the ribbon cable, and mating a pair of cable connectors, was successfully implemented.

Abstract A planetarium imitates a starry sky with physical and technical limitations using a dome, projector, and light source. It is widely used for entertainment, and astronomy and physics educations. In our previous study, we investigated the evaluation for faithful reproduction of a star field in a planetarium by performing psychometric experiments with 20 observers for plural projection patterns with different reproduction factors (color, luminance, and size of projected stars). In this study, we investigate the relationship between faithfulness and preference of a star field in a planetarium through a psychometric experiment with 47 observers. The experimental procedure followed the previous study. The rating of faithfulness improved for the projection pattern with a smaller star size. For the preference evaluation, the projection pattern with low luminance significantly lowered the preference rating. The results of the experiment indicate that the preferable star reproduction was different between male and female observers, whereas the faithful star reproduction was not significantly different in the evaluations between male and female observers. The male observers sought a faithful star reproduction as the preferred reproduction. In contrast, the female observers did not feel the faithful star reproduction preferable, and evaluated the more brilliant star reproduction as the preferred reproduction. These results were not dependent on the experience in astronomical observations.

Based on the current situation of high precision and comparatively low APA (absolute positioning accuracy) in industrial robots, a calibration method to enhance the APA of industrial robots is proposed. In view of the "hidden" characteristics of the RBCS (robot base coordinate system) and the FCS (flange coordinate system) in the measurement process, a comparatively general measurement and calibration method of the RBCS and the FCS is proposed, and the source of the robot terminal position error is classified into three aspects: positioning error of industrial RBCS, kinematics parameter error of manipulator, and positioning error of industrial robot end FCS. The robot position error model is established, and the relation equation of the robot end position error and the industrial robot model parameter error is deduced. By solving the equation, the parameter error identification and the supplementary results are obtained, and the method of compensating the error by using the robot joint angle is realized. The Leica laser tracker is used to verify the calibration method on ABB IRB120 industrial robot. The experimental results show that the calibration method can effectively enhance the APA of the robot.

The associations for CAM use are only occasionally differentiated by gender in populations where both male and female cancer survivors occur. The aim of this study is to describe the prevalence of CAM use in individuals with a previous cancer diagnosis and to investigate gender differences regard to factors associated with use. A total of 12982 men and women filled in a questionnaire with questions about life style and health issues. Eight hundred of those had a previous cancer diagnosis of whom 630 answered three questions concerning CAM use in the last 12 months. A total of 33.8% of all cancer survivors reported CAM use, 39.4% of the women and 27.9% of the men (). The relationship between the demographic variables and being a CAM user differed significantly between men and women with regard to age (), education (), and income (). Female CAM users were more likely to have a university degree than the nonusers, while male CAM users were more likely to have a lower income than the nonusers. According to this study, prevalence and factors associated with CAM use differ significantly between male and female survivors of cancer.

<p>The present study was aimed to examine the relationship between psychological empowerment and spiritual intelligence with marital satisfaction in male and female teachers in Ahvaz from 2014 to 2015. Hence, 350 teachers were selected using random-stratified sampling method. Research tools were Spriters' psychological empowerment questionnaire (1995), Badie's et al. spiritual intelligence questionnaire (2010), Enrich's marital satisfaction questionnaire (1997); in order to do analysis, a Pearson Correlation Coefficient method and a regression method was used. Results showed that there is a relationship between psychological empowerment and spiritual intelligence with marital satisfaction in male and female teachers in Ahvaz. The results obtained from multi-fold regression analysis, using step-by-step method, showed that effectiveness, spiritual intelligence, and significance are able to predict marital satisfaction significantly. In addition, psychological empowerment has a closer relationship with spiritual intelligence, and spiritual intelligence has a closer relationship with marital satisfaction. </p>

The Relationship

The Psychological Skills Inventory for Sport (PSIS; Mahoney, 1988) identifies certain psychological skills or characteristics possessed by successful athletes. However, little has been done to connect the PSIS with other variables that may have an impact on the athletes’ psychological skills. Therefore the purpose of this study was twofold. First, the psychometric properties of the PSIS for all subjects and by gender were determined. Second, the relationship between the PSIS, experience, practice commitment, and gender of collegiate skiers was examined. A random sample of 131 male and female collegiate skiers responded to the 45-item PSIS. Overall, the six PSIS subscales (anxiety, concentration, confidence, mental preparation, motivation, and team emphasis) demonstrated acceptable internal reliability (coeff. alpha = .69−.84). Results of a 4 × 3 × 2 (Experience × Practice Commitment × Gender) MANOVA and follow-up univariate F tests revealed a significant gender effect on the team emphasis subscale. Female collegiate skiers were more team oriented than male collegiate skiers and placed more importance on the social and affiliative aspects of being on a team than did their male counterparts.

<p><strong>Objective</strong><strong>: </strong>This study investigated the relationship between foot type and ankle sprain incidence.</p><p><strong>Method</strong><strong>: </strong>In a prospective cohort study using the FPI, 68 adult male and female indoor football (Futsal) players were measured and their feet were classified according to foot posture index (FPI) as neutral, supinated and pronated. They were followed over 6 month as a one competition season and at the end, any injuries at the ankle during this period were detected.</p><p><strong>Result</strong><strong>: </strong>There was no significant association between FPI score (considering the total FPI score and its six components) and occurrence of ankle sprain. Also, no association was existed between gender, age, height, weight, BMI, duration of professional exercise, dominant foot and occurrence of ankle sprain. In this study, the history of previous ankle sprain was the only significant predictor of the occurrence of ankle sprain in the follow-up period. Participants with the positive history of previous ankle sprain were at higher risk of developing new ankle sprain (OR=6.02, 95% CI: (1.93, 18.84), p=0.002).</p><p><strong>Conclusion</strong><strong>: </strong>There was no significant association between FPI score and occurrence of ankle sprain.<strong></strong></p><p><strong>Limitation: </strong>there was scarce of supinated foot in the study so evaluation of relationship between supinated feet and ankle sprain was not applicable.</p>

The Relationship

Blood samples were collected from five pregnant sows from day 111 postbreeding to farrowing and from their piglets at regular intervals between birth and 48 h. The time between birth and first suckling (BTS) was recorded for each piglet. Maternal serum testosterone (T) levels were detectable only at the beginning of parturition and were highly correlated (r = 0.83) with litter BTS. Serum T levels of male and female piglets were similar at birth. In male piglets the T levels increased to a peak 2 h after birth and decreased gradually thereafter. In contrast, the T levels of female piglets declined rapidly after birth to baseline levels. The BTS of female piglets was shorter than that of male piglets. Body weight of males was higher than that of females and was influenced by litter size. These results suggest that the higher serum T levels of male piglets may have a detrimental effect on their teat-seeking ability. Key words: Serum testosterone, sex, piglets, teat-seeking ability, sow
