The onset of the rainy season in this area is one such climate event, and it has occurred earlier and with less regularity in recent years. Not all households are able to cope with these changes. This study examines the ability of local farmers to cope with rice insufficiency. This investigation also clarifies household strategies in dealing with the climate event. We randomly interviewed 63 of 95 household heads, and performed a paired sample t test to examine the significance of differences in three household groups between the 2010 normal climate and the 2011 climate event. The groups were categorized according to rice selfsufficiency in 2011: groups I are households with rice self-sufficiency, group II are those facing a rice shortage of up to 3 months, and group III are those with insufficient rice for over 3 months. We also conducted a one-way ANOVA to examine the significance of differences in livelihood strategies among the three groups. We found that the household labor force was the most important factor in enhancing the villagers' ability to deal with the climate event and that the level of impact of that event shaped their coping strategies. Households with substantial labor force had more options for coping strategies than those with smaller ones. The villagers faced different levels of impact and adopted differentcoping strategies accordingly. Non-timber forest product collection was the principle livelihood strategy in response to non-climate factors such as education, access to health services, provision of equipment and clothing, and overcoming the impact of the climate event. Households heavily affected by the early rainy season onset tended to engage in intensive activities such as off-farm activity and outside work, rather than their major livelihood activities in the village(upland crop and livestock production).展开更多

Firstly, our paper analysis differences of overall and individual for the two groups of raters. The analysis method is： first check the score whether meets the normal distribution or not by Chi-square and then test whether the mean of the two group＇s ratings is equal or not, through t-test, to illustrate the differences of the two groups＇ ratings. Secondly this paper respectively characterizes the credibility of each group＇s rating with the variance and gray correlation. Both the results are highly consistent on the credibility, so they can support each other. This score comparison method can be further extended to a similar scoring system.展开更多
Objective: To observe the therapeutic effects of peridural injection of Mailuoning Compound Liquor (脉络宁复合液) for prolapse of lumbar intervertebral disc (PLID).

Methods: Peridural injection of Mailuoning Compound Liquor (MCL) was given to 100 cases of PLID, once a week, 4 sessions constituting a therapeutic course. By adopting the scoring method, observations were carried out on the total therapeutic effect and changes in the 13 items of the symptoms and signs. Results: After treatment, the JOA scores in this series of patients were markedly enhanced as compared with the scores before treatment, showing significant differences in the paired t test (P<0.05). The sum of the excellent and good rates was 64%, and the total effective rate was 97%. All the scores in the 13 items under observation were significantly raised as compared with the scores before treatment (P<0.05). Conclusion: Peridural injection of MCL is an effective and safe therapy for PLID, and with shorter treating course, quicker therapeutic effects, and less suffering for the patients.展开更多
