我国经济周期波动性与阶段性之间关联的非对称性检验——Plucking模型对中国经济的实证研究

In this paper we used the Plucking model to test the asymmetric patterns in China’s business cycle. We find the evidences that there is a significant plucking effect in output growth. The negative shock to output is not able to influence the growth trend in long run. The growth could return to its trend more quickly after the economy recoveries from the contracting phase in business cycle. These empirical findings suggest that the macroeconomic control has play the roles of stabilizing economy, and the abilities of keeping rapid and stable growth have been enforced.

Developing Situations of Tea Plucking Machine

To acquire the developing trend and ways of mechanization of tea plucking, with analyzing the developing backgrounds and situations of tea plucking machine both at home and abroad, this paper obtains the conclusion that there are several countries that have conducted a lot of studies on tea plucking machine, such as Japan, England, France, India, Australia and Argentina. Among others, Japan goes ahead, where lots of researches have been conducted in the highest developing level. The article also analyses the reason why China has a poor mechanization of tea plucking and points out existing problems. Finally, some advices and measures for developing Chinese domestic mechanization of tea plucking are given.

Clinical efficacy of HEGU needling method combined with tendon-stretching and plucking massage on trigger point in the treatment of acute thoracodorsal myofascitis

Objective:To observe the effect of Hegu neediling method combined with tendon-stretching and plucking massage on trigger point in the treatment of acute thoracodorsal myofascitis. Methods: A total of 84 patients with acute thoracodorsal myofascitis who met the diagnostic and inclusion criteria were assigned into the treatment group and the control group randomly, the treatment group was treated with Hegu neediling method combined with tendon-stretching and plucking massage, while the control group was treated with conventional electroacupuncture. Two groups of patients were treated for two weeks. VAS score and ODI were compared before treatment, after the first treatment and after the treatment course, and the clinical efficacy was evaluated after treatment.Results: The total effective rates of the treatment group and the control group were 97.62% and 80.95%, respectively. The treatment group was significantly better than the control group. The VAS and ODI scores of the treatment group decreased after the first treatment and the end of the treatment, and the treatment group was significantly better than the control group.Conclusion:Hegu neediling method combined with tendon-stretching and plucking massage can relieve pain and improve limb dysfunction in patients with acute thoracodorsal myofascitis.

Business Cycle Asymmetry in China:Evidence from Friedman's Plucking Model

Friedman＇s plucking model of business fluctuations suggests that output cannot exceed an upper limit, but it is occasionally ＂plucked＂ downward below trends as a result of economic recessions. This paper investigates China＇s business fluetuations using quarterly real GDP data for the period 1978 2009. Our results show some evidence supporting Friedman＇s plucking model. We find that a ceiling effect of real output exists, and that negative asymmetric shocks significantly affect the transitory component, which captures the plucking downward behavior during the recession. The results also suggest that the basic asymmetric unobserved component model is not appropriate for directly modeling China＇s real output because the business＂ cycle is inaccurately measured, but it works quite well when considering a structural break in the second quarter of 1992. The results reveal that although China＇s economy strengthened in the second quarter of 2009, it is essential for China＇s government to take further positive and effective measures to maintain sustainable development of the economy.

Comprehensive evaluation of Korla fragrant pears and optimization of plucking time during the harvest period

To optimize the harvest of Korla fragrant pears and to provide a theoretical basis for post-harvest processing,a total of 26 basic indices of Korla fragrant pears,including their morphology,quality,and softening age,were investigated.The harvest period ranged from August 22nd to October 6th,samples were collected every 5 d(totally 10 plucking days,indicated as H1-H10).The results indicated that changes in pectin content were the main causes of softening in fragrant pears.The scavenging of free radicals mainly occurred because of the collaborative effects of superoxide dismutase(SOD)and catalase(CAT).In the harvest periods H1-H3,the hardness,titratable acid(TA),chlorophyll content,density,and diameter of the stone cells,as well as the cellulose and hemicellulose content of the Korla fragrant pears were at their highest.During the periods H7-H10,the single-fruit weight,fruit horizontal and vertical diameter,color coordinates L,a*,b*,soluble-solids content(SSC),SOD activity,CAT activity,and water-soluble pectin were higher than in the other plucking periods.The highest vitamin C(VC)content and moderate values for a variety of indicators were observed during H3-H7.Variations in the Korla fragrant pears during H1-H3 mainly manifested through changes in softening-related parameters.During H3-H10,changes in the softening-related,aging-related,color-related,and quality indices had a dominant role.On this basis,some suggestions for the post-harvest processing of fragrant pears have been proposed.Fruit,during H1-H3,are suitable for transportation and storage;during H7-H10 are suitable for fresh-eating and further processing;and during H3-H7,exhibited moderate values for a variety of indicators and had the highest commercial value.This research provides a systematic evaluation of the characteristics of mature Korla fragrant pears during the harvest period and can form the basis for fruit quality control and processing of Korla fragrant pears.

小儿拇指狭窄性腱鞘炎案

A female patient,13 months old,suffering from limited extension of the right thumb for 7 days,diagnosed as stenosing tenosynovitis of the thumb in children.Tuina(Chinese massage) therapy was adopted,in which,stimulation was applied with fingers instead of needles,including pressing and kneading,twisting and kneading,plucking,dorsal extending,rotating as well as pushing and rubbing manipulations.The whole procedure of manipulation lasted around 15 min,once every two days,3 times weekly.Meanwhile,the parents were advised to bath the child patient's right hand into warm water every day and fix the affected thumb with splint at night.After 12 treatments with tuina therapy,the flexion and extension function of the affected thumb were returned to normal and the thumb motor function was recovered.In 2 months of follow-up,the thumb motor function was normal and the stenosing tenosynovitis was not recurred.In this case,tuina therapy is adopted in treatment of stenosing tenosynovitis of the thumb in children.As an alternative method of surgery,tuina therapy has a satisfactory clinical effect.
