资源搜索是P2P网络的关键问题。目前P2P网络中资源搜索有多种机制,按照资源搜索机制的不同有多种网络模型。其中采用洪泛机制的Gnutella网络模型最接近纯粹的P2P网络,但是Gnutella中资源搜索所采用的洪泛机制因为消息过多冗余导致效... 资源搜索是P2P网络的关键问题。目前P2P网络中资源搜索有多种机制,按照资源搜索机制的不同有多种网络模型。其中采用洪泛机制的Gnutella网络模型最接近纯粹的P2P网络,但是Gnutella中资源搜索所采用的洪泛机制因为消息过多冗余导致效率低下而遭到众多质疑。基于这个原因,文中对采用洪泛机制的Gnutella协议做了改进,给出了改进后的协议,实验证明它比Gnutella协议具有明显的优越性。 展开更多

Following the current epidemic of obesity, the worldwide prevalence of nonalcoholic fatty liver disease(NAFLD)has increased with potential serious health implications. While it is established that in adults NAFLD can progress to end-stage liver disease in many cases, the risk of progression during childhood is less well defined. Since most obese children are not adherent to lifestyle modifications and hypocaloric diets, there is a growing number of studies on pharmacological interventions with the risk of disease mongering, the practice of widening the boundaries of illness in order to expand the markets for treatment. Here, we propose a critical appraisal of the best available evidence about long-term course of pediatric NAFLD and efficacy of treatments other than hypocaloric diet and physical exercise. As a result, the number of NAFLD children with a poor outcome is small in spite of the alarming tones used in some papers; large-scale longitudinal studies with longterm follow-up of pediatric NAFLD patients are lacking; the studies on ancillary pharmacological interventions have been performed in few patients with inconclusive and conflicting results. 展开更多

The growing number of people suffering from depression has become a social problem in Japan. The problems associated with depression in Japan have been influenced by the pharmaceuticalization of mental health. Since selective serotonin reuptake inhibitors were introduced to Japan's pharmaceutical market in 1999, demand for anti-depressant medications has rapidly expanded. It seems likely then that the efforts of pharmaceutical companies, as part of their marketing strategies, to increase people's awareness of mental illness have led people who are not actually depressed to have medical consultations and drug treatments for it. This phenomenon is known as "disease mongering" and has been reported on. Problems exist from the medical perspective also and include the following: expansion of the diagnostic criteria for depression as formulated in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders; treatments that rely heavily on drugs; and biomedicalization. Another reason for the increase in medical consultations is the declining function of communal bodies. This has resulted in individuals struggling psychologically, for example, with anxiety, worry, and depression. In summary, this sociological research analyzed the problems of depression in |apan and revealed how the pharmaceuticalization of mental health accelerates the individualization of social problem. 展开更多
