The application capability of IT plays the critical role, which determines the efficiency and effectiveness of the aforementioned four processes. The process model of IT impacts on firm competitiveness can also be used to explain why, under what situations and how IT can generate positive organizational outcomes, as well as theoretical bases for further empirical study.展开更多

Based on broad literature search, this paper summarized the identification, composition, pharmacology, clinical applications, ecological value, and cultivation technologies of S. japonica（Sw.） Ohwi, aiming at providing scientific information for further research and development of S. japonica（Sw.） Ohwi.展开更多
Objective: To study the value of gastroenterultrasound developer in diagnosis of the stomach tumor. Methods: 38 patients who diagnosed as stomach tumor by gastroscopy were chosen, and their images before and after by ...Objective: To study the value of gastroenterultrasound developer in diagnosis of the stomach tumor. Methods: 38 patients who diagnosed as stomach tumor by gastroscopy were chosen, and their images before and after by using gastroenterultrasound developer were compared. Results: The difference between the detectable rate of stomach tumor before and after by using gastroenterultrasound developer was significant (P < 0.01). Conclusion: Gastroenterultrasound developer has a high diagnostic value in diagnosis of the stomach tumor.展开更多
