Erectile dysfunction frequently occurs with diabetes mellitus. A survey of diabetic men was conducted by anonymous questionnaire to investigate the associations of erectile dysfunction with various predictive factors. A total of 112 diabetic males without an obvious history of erectile dysfunction were available for analyses. The mean age and duration of diabetes were 53.7?±?12.2 years and 10.2?±?8.6 years (mean?±?standard deviation), respectively. The questionnaire included questions on the presence or absence of smoking, hypertension, libido and subjective symptoms of diabetic neuropathy that may be associated with erectile dysfunction. Analysis of the answers to the questionnaire revealed that 40% of the patients complained of erectile dysfunction (erection ‘always insufficient’). Erectile dysfunction was significantly correlated with age (p?=?0.005), but not with duration of diabetes (p?=?0.25), adjusted for age. Erectile dysfunction was also associated with sensory neuropathy and reduced libido, independently of age. The logistic regression analysis revealed that erectile dysfunction was positively associated with reduced libido and age. The odds ratio of erectile dysfunction for reduced compared to unreduced libido was 18.21, suggesting that psychogenic factors have a marked influence on erectile dysfunction. It is concluded that the presence of erectile dysfunction should be considered when symptoms related to diabetic neuropathy are observed; psychological approaches, such as sexual counseling, could be applied for the treatment of erectile dysfunction.  相似文献

People can discriminate cheaters from cooperators on the basis of negative facial expressions. However, such cheater detection is far from perfect in real-world situations. Therefore, it is possible that cheaters have the ability to disguise negative emotional expressions that signal their uncooperative attitude. To test this possibility, emotional intensity and trustworthiness were evaluated for facial photographs of cheaters and cooperators defined by scores in an economic game. The facial photographs had either posed happy or angry expressions. The angry expressions of cheaters were rated angrier and less trustworthy than those of cooperators. On the other hand, happy expressions of cheaters were higher in emotional intensity but comparable to those of cooperators in trustworthiness. These results suggest that cheater detection based on the processing of negative facial expressions can be thwarted by a posed or fake smile, which cheaters put on with higher intensity than cooperators.  相似文献

This paper discusses John Ogbu and his work in the context of Japan. First, his interest in Japan, his interactions with Japanese educators and researchers, and their responses to his work are discussed. Then Ogbu’s cultural model from the author’s fieldwork experiences is examined and a relational and dialectic perspective is proposed to study ‘the system’ and ‘community forces’ to capture generational changes and the interethnic dynamics of the school–community relationship.  相似文献

People tend to turn their left or right cheek to express or conceal emotions, respectively. We examined the lateral posing bias for displaying trustworthiness during a trust game in which participants and their virtual partners cooperated or did not cooperate with their counterparts to earn a monetary reward. Right-handed participants (N = 81) were asked to pose for a photograph and then play the trust game. Participants showed an overall left posing bias (i.e., showing their left cheek to the camera). The left cheek bias was more stable for participants that cooperated very little in the trust game (non-cooperators) than for those that cooperated a lot (cooperators). In the rating experiment (N = 28 and 25), non-cooperators showing their left cheek were rated equally as trustworthy as cooperators. On the other hand, non-cooperators who showed their right cheek were rated as less trustworthy than cooperators. These results suggest that non-cooperators intuitively use the left hemiface to exploit others in social interactions.  相似文献

This article aims to construct a new perspective for analyzing the recent omnipresence of screens, the diversity of images, and their impact on our daily lives. Because of the diversification of digitalized images today, research based on film and television studies is unable to grasp the fluid relationships among screen images, spaces, and the bodies of their audience, and important task for recent scholarship is to determine how to include these screen images in media and cultural studies. In response to this issue, this article seeks to reconstruct the concept of screen practice, guided by the perspectives of Jonathan Crary and Friedrich Kittler on media and practices; Koji Taki and Ai Maeda's historical research on Japanese modernity; and Erkki Huhtamo and Yussi Parikka's media archaeological perspectives for screen and visual culture. Although the notion of screen practice was originally proposed in the field of film history, it should be expanded for broader screen cultures as the sites at which scientific discourses and technologies act on the bodies of viewers. Taking the experiences of Japanese modernity as its subject, this is a critical issue, because at these sites we can find traces of dynamic negotiations between the circulation of science and media derived from Western modernity, and existing physical and cultural vernacular practices. Moreover, going back to the screen cultures at the end of the 19th century will make clear how the process of our contemporary media environment was formed.  相似文献

In order to determine the threshold amount of alcohol consumption for blood pressure, we calculated the benchmark dose (BMD) of alcohol consumption and its 95% lower confidence interval (BMDL) in Japanese workers. The subjects consisted of 4,383 males and 387 females in a Japanese steel company. The target variables were systolic, diastolic, and mean arterial pressures. The effects of other potential covariates such as age and body mass index were adjusted by including these covariates in the multiple linear regression models. In male workers, BMD/BMDL for alcohol consumption (g/week) at which the probability of an adverse response was estimated to increase by 5% relative to no alcohol consumption, were 396/315 (systolic blood pressure), 321/265 (diastolic blood pressure), and 326/269 (mean arterial pressures). These values were based on significant regression coefficients of alcohol consumption. In female workers, BMD/BMDL for alcohol consumption based on insignificant regression coefficients were 693/134 (systolic blood pressure), 199/90 (diastolic blood pressure), and 267/77 (mean arterial pressure). Therefore, BMDs/BMDLs in males were more informative than those in females as there was no significant relationship between alcohol and blood pressure in females. The threshold amount of alcohol consumption determined in this study provides valuable information for preventing alcohol-induced hypertension.  相似文献

The objective of this study was to calculate benchmark durations and lower 95% confidence limits for benchmark durations of working hours associated with subjective fatigue symptoms by applying the benchmark dose approach while adjusting for job‐related stress using multiple logistic regression analyses. A self‐administered questionnaire was completed by 3,069 male and 412 female daytime workers (age 18–67 years) in a Japanese steel company. The eight dependent variables in the Cumulative Fatigue Symptoms Index were decreased vitality, general fatigue, physical disorders, irritability, decreased willingness to work, anxiety, depressive feelings, and chronic tiredness. Independent variables were daily working hours, four subscales (job demand, job control, interpersonal relationship, and job suitability) of the Brief Job Stress Questionnaire, and other potential covariates. Using significant parameters for working hours and those for other covariates, the benchmark durations of working hours were calculated for the corresponding Index property. Benchmark response was set at 5% or 10%. Assuming a condition of worst job stress, the benchmark duration/lower 95% confidence limit for benchmark duration of working hours per day with a benchmark response of 5% or 10% were 10.0/9.4 or 11.7/10.7 (irritability) and 9.2/8.9 or 10.4/9.8 (chronic tiredness) in men and 8.9/8.4 or 9.8/8.9 (chronic tiredness) in women. The threshold amounts of working hours for fatigue symptoms under the worst job‐related stress were very close to the standard daily working hours in Japan. The results strongly suggest that special attention should be paid to employees whose working hours exceed threshold amounts based on individual levels of job‐related stress.  相似文献
