An examination of financing structure in SMEs of China based on panel data
Xiaomao Zhang,Haizhen Li 인하대학교 정석물류통상연구원 2009 인하대학교 정석물류통상연구원 학술대회 Vol.2009 No.10
This paper using panel data investigates empirically how some main factors determine the financing structure of SMEs in China from 2002 to 2006. The empirical resutls reveal that the factors in a positive relationship with financing structure include the scale, the finance scrape, the asset structure, and the asset manage ability. The factors in a negative relationship with financing structure include the solvency, the profitability, the ability to generate internal resources, the revenue effect, the ability of convert assets to cash, and the ownership structure. Beside this, there is no significant relationship between financing structure and the character of ownership.

Adsorption, Mobility and Degradation of Diphenamid in Chinese Soils
Xiaomao Wu,Ming Li,Youhua Long,Renxiang Liu,Yunlong Yu,Hua Fang 대한토목학회 2012 KSCE Journal of Civil Engineering Vol.16 No.4
The present study was conducted to determine adsorption, mobility, and degradation characteristics of diphenamid in five Chinese soils and their relationships. The adsorption of diphenamid in soils tested could accurately be described by a Freundlich equation. Based on the mobility factor (Rf), diphenamid was seen to be slightly or moderately mobile in soils studied. Regression of Kf and Rf against selected soil properties indicated that Organic Matter (OM) was the most influential factor governing adsorption and mobility of diphenamid (r2 > 0.92 ) followed by clay (r2 > 0.61). There was a significant correlation (p < 0.01) between Kf and Rf of diphenamid. Diphenamid degradation data were fitted the first-order reaction equations, yielding half-lives (T1/2) ranging from 187.3to 247.5 days in unsterilized soils but prolonging to 577.5-630.0 days in sterilized soils. The prolonged T1/2 by sterilization showed that microbial degradation was the dominant pathway for diphenamid degradation in soils. Degradation of diphenamid in soils appeared to be influenced by soil OM (r2 > 0.97) and clay content (r2 > 0.85). The T1/2 of diphenamid was significantly related to both Kf and Rf (p < 0.05), indicating that either Kf or Rf might be used as a model for predicting degradation of diphenamid in soils involved.

Objective: To investigate the prognostic value of metabolic tumor volume (MTV) and totallesion glycolysis (TLG), measured by preoperative 18F-fluorodeoxyglucose positron emissiontomography/computed tomography (18F-FDG PET/CT), in risk stratification of patients withendometrial carcinoma (EC). Methods: The patients with pathological diagnosis of EC who underwent preoperative18F-FDG PET/CT imaging were retrospectively selected for analysis of the prognostic valuesof PET parameters in risk classification and lymph node metastases (LNMs). Receiveroperating-characteristic analysis was used to analyze the correlation of PET parameters cutoffvalues with deep myometrial invasion (MI), lymphovascular space involvement and LNM forprognostic values in risk stratification. Results: The sensitivity, specificity, positive predictive value, negative predictive value andaccuracy for detection of LNM are 83.3%, 99.7%, 90.9%, 99.5% and 99.2%, respectively. TheMTV and TLG of primary lesion of EC in the patients with LNM are notably higher than thosein patients without LNM, p<0.010. The MTV and TLG of the EC primary lesions in high-riskpatients are significantly higher than those in low-risk patients (p<0.010), but the maximumstandardized uptake value (SUVmax) is not. The MTV and TLG of primary lesions weresuperior to SUVmax for predicting of deep MI, LNM and high-risk of EC (p<0.005). Conclusion: MTV and TLG of primary lesions are more valuable in predicting riskstratification of EC patients. Preoperative 18F-FDG PET/CT imaging is useful in predictingthe LNM of EC and may help guide pelvic lymphadenectomy to avoid unnecessary pelviclymphadenectomy in EC patients with low-risk stratification.
