Research on the Computer Music Production Technology System under the Digital Background
Yong Mei Li,Jingqiu Liu,Yi Wen Zhang,Chen Chen,Xuan Guan 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.11
Computer music, as an important product of the information and digital age, belongs to the systems engineering combining the musical discipline with computer information control technology science. Through the applied research on digitalized acoustical signals, characteristic analysis of computer music, computer MIDI production technology, digital audio technology and computer music production software, this paper builds up a set of computer music production technology system based on a digital, informational and modernized background, and proves by experiments that this system makes the computer music production technology represent effects of simple and convenient usage, high-degree simulation and efficient extraction.

Purpose: To perform a retrospective review of the clinicopathological features of patients with conventional and non-conventional renal cell carcinoma (cRCC and ncRCC). Materials and Methods: A large prospectively maintained uro-oncological registry was accessed to extract clinicopathological data of patients diagnosed with renal tumors who subsequently underwent nephrectomy from 1990–2019. Demographics and operative parameters were extracted. Analyses of overall survival (OS) and cancer-specific survival (CSS) were performed using the Kaplan–Meier method. Cox proportional-hazards analysis was used to identify risk factors which influenced survival. Results: There were a total of 1,686 consecutive nephrectomies which was retrieved, with 1,286 cRCC and 400 ncRCC. The commonest ncRCC subtypes were papillary (n=198, 11.7%), clear cell papillary (n=50, 3.0%) and chromophobe (n=49, 2.9%) RCC. Kaplan–Meier estimates of OS were higher in cRCC (0.74; 95% confidence interval [CI], 0.71–0.78) than ncRCC (hazard ratio, 1.47; 95% CI, 1.16–1.87). Among individual subtypes, chromophobe RCC had the highest 5-year OS (0.90; 95% CI, 0.79–1.0). Among ncRCC subtypes, acquired cystic RCC demonstrated the highest association with end-stage renal failure and hypertension, with the highest CSS. MiT family translocation RCC had the youngest mean age at presentation (45.6±12.8 y) and excellent CSS. Factors associated with increased OS in the entire cohort included shorter operative time, partial nephrectomy and lower tumor stages. Conclusions: This study provides a comprehensive contemporary overview of ncRCCs which are yet poorly characterized, in comparison to cRCCs. Data from this study would contribute towards tailored patient counseling and healthcare resource planning.
