A numerical analysis technique that incorporates Voronkov's model were examined and used to estimate the distribution of defects during crystal growth. By comparisons of the distribution of the density of LSTd and the position of r-OSF in non-nitrogen-doped (non-N-doped) and nitrogen-doped (N-doped) silicon crystals, it is found that the results of the numerical analyses agree with practically evaluated data. The observations suggest that the r-OSF nucleus is a VO2 complex that is formed by bonds between oxygen atoms and residual vacancies consumed during the formation of void defects. This suggests that Voronkov's model can be used to accurately predict the generation and growth of defects in silicon crystals. This numerical analysis technique was also found to be an effective method of estimating the distribution of defects in silicon crystals during crystal growth.

＜正＞Since Kyoto COP3 meeting, general interest for reduction of carbon dioxide emission has been increasing. Furthermore, there is a global trend to regulate usage of hazardous materials in every commercial product, e.g. roHS and rEACH in Europe. It is believed that consciousness of global environmental issues has become the most critical matters of

AIM To assess the clinical characteristics of patients with complicated erosive esophagitis(EE) and their associated *** This prospective, cross-sectional study included patients diagnosed with EE by upper gastrointestinal endoscopy between October 2014 and March 2015 at 106 Japanese hospitals. data on medical history, general condition, gastrointestinal symptoms, lifestyle habits, comorbidities, and endoscopic findings were collected using a standard form to create a dedicated database. Logistic regression analysis was used to calculate adjusted odds ratios(aO r) and 95%CI for the association with complicated *** during the study period, 1749 patients diagnosed with EE, 38.3% of whom were prescribed proton pump inhibitors(PPIs) were included. Of them, 143(8.2%) had EE complications. Esophageal bleeding occurred in 84(4.8%) patients, esophageal strictures in 45(2.6%) patients, and 14(0.8%) patients experienced both. Multivariate analysis showed that increased age(a Or: 1.05; 95%CI: 1.03-1.08), concomitant use of psychotropic agents(a Or: 6.51; 95%CI: 3.01-13.61), and Los Angeles grades B(a Or: 2.69; 95%CI: 1.48-4.96), C(aO r: 15.38; 95%CI: 8.62-28.37), and d(aO r: 71.49; 95%CI: 37.47-142.01) were significantly associated with complications, whereas alcohol consumption 2-4 d/wk was negatively associated(a Or: 0.23; 95%CI: 0.06-0.61). Analyzing associated factors with each EE complication separately showed esophageal ulcer bleeding were associated with increased age(a Or: 1.05; 95%CI: 1.02-1.07) and Los Angeles grades B(aO r: 3.60; 95%CI: 1.52-8.50), C(a Or: 27.61; 95%CI: 12.34-61.80), and d(a Or: 119.09; 95%CI: 51.15-277.29), while esophageal strictures were associated with increased age(a Or: 1.07; 95%CI: 1.04-1.10), gastroesophageal reflux symptom(aO r: 2.51; 95%CI: 1.39-4.51), concomitantuse of psychotropic agents(a Or: 11.79; 95%CI: 5.06-27.48), Los Angeles grades C(aO r: 7.35; 95%CI: 3.32-16.25), and d(a Or: 20.34; 95%CI: 8.36-49.53) and long-
