5G Wireless: Technology, Standard and Practice

5G wireless technology is developing at an explosive rate and is one of the biggest areas of research within academia and industry. With 2G, 3G and 4G, the peak service rate is the dominant metric that distinguishes these three generations. 5G will significantly increase the peak service rate but will also dramatically increase energy efficiency, frequency efficiency, spectral effi- ciency, and efficiency of other resources. It will dramatically increase flexibility, ca- pacity, coverage, compatibility and convergence. In this way, it will salisfy the in- creasing demands of emerging big-data, cloud, machine-to-machine, and other ap- plications. The successful development and deployment of 5G technologies will be challenging and will require huge effort from industrry, academia, standardizalion organizations, anti regulatory authorities.

Application Experience of Quality Feedback in Standardized Practical Skills Training for Clinicopathology Residents

In recent years,there are increasingly more standardized trainings for doctors based on the standardized training outline that is suitable for different grades.Hierarchical training has gradually formed a relatively sound training mode.In reflecting students’learning effect,there is a need for an ideal quality feedback system in the standardized practical skills training for clinical pathology residents.This feedback system can help students achieve the training objectives through understanding and grasping the learning content.

VR赋能的生产现场可视化管理标准实践——以铁路车辆检修车间安全培训为例

Safety training and visual management are important tasks for production companies.In the railway vehicle maintenance industry,the tasks are particularly complex.Relevant national standards point out the direction for enterprise visual management,but they still require detailed research in order to combine with advanced information technology.This paper develops a system for safety training of railway vehicle maintenance based on virtual simulation technology,and conducts the application verification in a real world scenario,which is expected to provide reference for the standardization construction of enterprise visual management.

Routine Episiotomy Practice at a Tertiary Care Center in Saudi Arabia

Background: Episiotomy is a common perineum incision preformed to facilitate the delivery. Although it was commonly performed especially in primigravida women, the new trend is to limit episiotomies as much as possible. This study aimed to find out the rate of episiotomy and to compare the rate in primigravida vs multigravida at King Abdulaziz university hospital. Methods: A retrospective chart review was performed at King Abdulaziz University Hospital, Jeddah from January 2012 to December 2015. Ethical approval was obtained. Results: 35% of the females in 2012 had episiotomy while the majority of the vaginal deliveries had no intervention (65%). In 2015, the rate of episiotomies has increased to 36.4%. However, the majority of the vaginal deliveries had no intervention (63.6%). Overall 87.6% primigravidas had episiotomy while only 12.4% delivered without intervention. On the other hand, only 16.1% multigravidas had episiotomy, while the largest portion of cases was delivered without intervention (83.9%). Conclusion: Rate of episiotomy has slightly increased in 2015 in comparison to 2012. To decrease the overall episiotomy rate, we have to review KAUH guidelines and evaluate the limitation of applying it in practice.

New European Union＇s Requirements and IFRS Practice Statement ＂Management Commentary＂： Does MD＆A Disclosure Quality Affect Analysts＇ Forecasts？

The Management Discussion and Analysis （MD＆A） is a mandatory document under the European Union＇s （EU） law. In 2003, the EU issued Directive 2003/51/EC, which broadened the information that firms have to provide in their MD＆A, and in 2010 the International Accounting Standards Board （IASB） issued the International Financial Reporting Standards （IFRS） Practice Statement ＂Management Commentary＂, a non-binding guidance for the presentation of this document. The aim of this paper is to examine the relationship between MD＆A disclosure quality and properties of analysts＇ forecasts. In fact, although most studies found that financial analysts mainly refer to financial statement data in forecasting earnings, there are few researches highlighting the importance of MD＆A disclosures for financial analysts. On this basis, Ramnath, Rock, and Shane （2008） called for researches in order to better understand the relationship between the information really used by analysts and their forecasts. To assess the quality of MD＆A disclosures, we developed a multidimensional measure on the basis of the EU requirements and the IFRS Practice Statement, and then we regressed this variable on both forecast accuracy and dispersion. The findings show that our measure of MD＆A disclosure quality is significantly and positively related to forecast accuracy. We conducted other analyses in order to better understand the previous relationship and we found that, if we analyze the different information contained in the MD＆A statement, financial analysts consider useful accounting and financial data in forecasting earnings. These results enhance our understanding of the role of MD＆A disclosures in the wide set of information that firms provide to financial statement users.

Sieving Error from Dry-Separating Silt-Sand-Gravel Soils

The dry-separation method is an alternative to the wet-preparation in the current European Standard for the determination of particle size distributions by the sieving of soils. Due to the risk of error, dry-separation is cautioned against in the standard;however, there is no additional guidance as to when it is unsuitable nor for the magnitude of error that it may introduce. This study investigates the dry-separation method as an alternative by comparing with the conventional method of Wet-preparation in terms of particle-size distributions of eight cohesionless sand-gravel soils with varying amounts of nonplastic fines. The findings indicate a gradually increasing sieving error for fractions at minus 0.5 mm with the amount of fines in the soil, and depending on the fines content of the soil, dry-separation introduced errors upwards of 45% in silt-sand-gravel soils. An empirical best-fit formula is proposed for the estimation of the error using the dry-preparation method on this type of soil. Furthermore, to avoid sieving errors, the results suggest that the dry-separation method should not be used for silt-sand-gravel soils exceeding 2% silt size fractions.
