Objective: intervene a workline throughout ergonomic approach to diminish incidence of Carpal Tunnel Syndrome (CTS). Methods and Materials: an ergonomic intervention study was developed in workstations with highest index of musculoskeletal disorder (MED) associated to cumulative trauma. The Deparis method, Reba and Ocra check list methods were used, also morbility reviewes. National and international ethics criteria were carried out. Results: workers identified 3 fundamental issues using the Deparis method: repetitive activities, postures adopted and uncomfortable furniture. The analysis of the workstation with Reba and Ocra methods before the changes, evidenciated that 56% of postures adopted were high risk postures, the 44% remaining were medium and low-risk. Following the active pause program (APP), furniture changes and work rhythm decrease, was noted that the risk of suffering MED decreased. The morbility review, drop in consults of musculoskeletal system (MES) related to CTS observed. The APP was well accepted by women, but not initially men. Discussion: the research show that when the work rhythm decreases, the symptom of MES related to CTS have a remarkable decrease, also that changes in the furniture, generate great ergonomic differences and changes in the work environment are not possible if workers don't empower the tools to make-it.  相似文献

Employed individuals from a range of jobs (n=18) were interviewed using a repertory grid technique, to explore the criteria they used to distinguish between different jobs. The concepts of 'a good job' and 'a job good for health' were also discussed. Interactions with others and the job itself were the most commonly used criteria and were also the most common features of a 'good job'. Pay and security were mentioned frequently but were less important when comparing jobs and when defining a 'good job'. Physical activity was rarely associated by interviewees with a 'good job' but was frequently associated with a 'job good for health'. A comprehensive definition of a 'good job' needs to take all these factors into account.  相似文献

To predict the technology acceptance of a system before market release is one of the big challenges of today. Many models are concerned with the question if someone is going to accept the system or not. Within this work a first empirical investigation of a personal trait called Pleasure of Control (PoC) is presented. Pleasure of Control is a construct that divides people into those people enjoy having control over a technical system and those who do not. It is predicted that a high Pleasure of Control leads to a prolonged system usage and unwillingness to accept highly automated systems. This paper presents a first empirical investigation of Pleasure of Control with 10 Persons with focus on usage durations. An experimental study revealed differences in the usage durations of a technical system (Apple iPad) between users with high and user with low Pleasure of Control measures.  相似文献

In June 1986, Population and Development Review published a highly influential article by John Caldwell entitled “Routes to Low Mortality in Poor Countries.” Amid growing anxiety over decelerating world mortality decline, Caldwell explored social and political pathways to mortality success on the basis of two lists of superior mortality achievers and exceptionally poor mortality achievers, countries whose mortality rankings drastically differed from their income rankings. To mark the quarter-century since Caldwell's study and chart new pathways, this article looks at the subsequent performance of Caldwell's original exceptional achievers and develops an updated list of achievers. Analysis highlights the presence of many more poor achievers today; the rising importance of adult mortality as a marker of exceptional achievement; the increasing success of countries in Latin America and the Muslim world; the continued success of China, Vietnam, Cuba, and Costa Rica. dramatic improvements in schooling outcomes, particularly for women, have reduced the importance of education as a determinant of superior achievement. Reinforcing Caldwell's original assertions, the synthesis highlights how interactions between social consensus, health care systems, and human capital dependence offer a pathway to superior achievement. These forces may be especially powerful at moments of national crisis.  相似文献

Unmet need for behavioral health care is a serious problem for crossover youth, or those simultaneously involved with the child welfare and juvenile justice systems. Although a large percentage of crossover youth are serious emotionally disturbed, relatively few receive necessary behavioral health services. Few studies have examined the role of interagency collaboration in facilitating behavioral health service access for crossover youth. This study examined associations for three dimensions of collaboration between local child welfare and juvenile justice agencies - jurisdiction, shared information systems, and overall connectivity - and youths' odds of receiving behavioral health services. Data were drawn from the National Survey of Child and Adolescent Well-Being, a national survey of families engaged with the child welfare system. Having a single agency accountable for youth care increased youth odds of receiving outpatient and inpatient behavioral health services. Inter-agency sharing of administrative data increased youth odds of inpatient behavioral health service receipt. Clarifying agency accountability and linking databases across sectors may improve service access for youth involved with both the child welfare and juvenile justice systems.  相似文献

在美国威斯康星州的灵长目研究中心,研究者观察到一对熊猴幽会的情景:名叫琼伊和哈尼的两只熊猴悄悄离开猴群,从"里屋"溜到了空荡荡的"外屋",打算进行一次"爱的冒险".琼伊在群猴中排名第三,按规则,这种好事还轮不到他.但这名胆大妄为者达到了目的,并发出了兴奋的喊叫.这让哈尼有点紧张,她猛地回头看了琼伊一眼,目光中含着责备和威吓.琼伊似乎领会到了对方的意思,将噘成圆圈向前翻伸的嘴唇收了回来,开始安静地享受那一切.还好,先前的叫声没有引起其他熊猴的注意.  相似文献

Considerable interest in the area of youth gambling has prompted an increase in empirical investigations examining the correlates associated with youth experiencing severe gambling problems. Based upon the current state of knowledge and our clinical experience, the development of the treatment program for youth with serious gambling problems employed at the McGill University Youth Gambling Research and Treatment Clinic is described. The major tenets, underlying philosophy, and therapeutic processes are presented. A case study is included to illustrate the therapeutic approach. The authors present the need for greater funding for more basic and applied research and the necessity for further scientifically validated treatment and prevention programs.  相似文献
