The objective is to study the psycho-emotional aspects and risk factors associated with civil servants onerous retirement. Methods: It was a descriptive and cross-sectional study which involved 233 pensioners met at the Public Treasury’s Revenue Office in Parakou from June 1 to August 30, 2013. Data were collected through an interview on vulnerability criteria, and Hamilton Depression Rating Scale was used in assessing both anxiety level and depressed mood. Results: Pensioners’ average age was 61.1 ± 6.7 years. Males aged 50 to 60 years represented 47.2%. Following the announcement of retirement, 88.9% had feelings of fear, and 75.8% showed moderate to severe anxiety prevalence of which 88.2% were females and 73.9% males. The distribution according to professional categories was as follow: A (77.3%);B (72.6%);C (69.2%);(85.5%);E (85.7%). Retirement risk factors were: dependants (73.1%), age-related disorders (40.3%), lack of health insurance coverage (24.6%) resulting in a depressed mood (36%) strongly associated with a feeling of family and social abandon (87.8% P = 0.02). Conclusion: Depending on job onerousness in each professional category and associated psycho-social risk factors, it is important to implement an adequate action plan in view of promoting pensioners mental health.展开更多

The calculation formulas of output power and average temperature of Stirling reversible heat engine were deduced, which disclosed the relationship between average temperature and ultimate pressure. A set of theoretical calculation formula of Stirling reversible heat engine was explored by combining definition of efficiency of heat engine. Research results provide theoretical references to design of parts and control system of Stirling reversible heat eneine.展开更多
