Reliable and stable island power supply system is an important guarantee for the development of the island. Based on the island connected to the main network by cable, this paper proposes an interactive multi-energy complementary microgrid consisting of new energy generation, electric energy interaction, electric vehicle charging and discharging, home photovoltaic system, power distribution and emergency rescue. The electricity generated by the residents themselves can be used by themselves, and the excess can be sold back to the main network. This system makes full use of the characteristics of electric vehicles energy storage and mobility and participate in grid dispatching, which can improve the popularity of new energy power generation, balance the peaks and valleys of island electricity consumption and reduce the cost of electricity for residents.

Objective: Silent cerebral ischemia (SSI) is found on cranial imaging, with no signs of stroke and has similar risk factors as stroke. There are few studies evaluating the relationship between SSI and AF. In this study, we aimed to evaluate left atrial functions and atrial mechanical delay (AED) in SSI cases with noninvasive tissue doppler imaging (TDI). Method: 39 SSI and 29 healthy subjects as control group included in this study. Atrial conduction times calculated by Tissue Doppler Imaging (TDI), demographic features, laboratory findings, ECG, transthoracic ECO were recorded. AED was calculated by measuring the lateral mitral annulus (PA lateral), septal mitral annulus (PA septum) and right ventricular tricuspid annulus (PA tricuspid) by TDI. Left atrial volumes were measured in the apical fourchamber view with the disk method. Left atrial mechanical functions were evaluated. The heart rate variability parameters of the patient group were compared by the holter. Results: The mean age of 39 patients (32K/7E) was 51 ± 10 years and the mean age of 29 healthy controls (24K/5E) was 48.8±5.9 years. There was no difference between the two groups in demographic characteristics (p>0,05). Blood glucose was significantly higher in the SSI group (p=0.034). Parameters related to AED were not statistically significant in the SSI group but were found longer (p>0.05). The parameters of left atrial function such as LAPEF (0,3±0,1 versus 0,2±0,1, p=0,050), LAPEV (12,1± 6,8 versus 10,3±8, p=0,197) and LATEV (23,6±11,1 versus 21,6±9,4 p=0,496) were higher but were not statistically significant. Conduit volüm (26,8±12,7 versus 21,5±16,5, p=0,017), LVEDV (91,8±24,4 versus 74,8±25,3. P=0,002) and LVESV (41,4±13,4 versus 31,7,8±15,7. P=0,003) was found statistically significant. Conclusion: Regulation of blood glucose of SSI cases and follow-up the patienst for cardiac diastolic functions, and taking into consideration that these changes may lead to prolongation at the time of atrial conduction are important.

This paper is based on panel data of 30 provinces and cities in China from 2008 to 2017, The convergence of innovation efficiency is tested by σ convergence and β convergence test, Using stochastic frontier model and principal component analysis to analyze the impact of Chinese science and technology finance on entrepreneurial efficiency. The study found: Venture capital investment is more flexible than the output of entrepreneurial man-power investment, technology finance has a significant positive impact on entrepreneurial efficiency, but there is a problem of regional development imbalance. Convergence and divergence analysis found, the gap in entre-preneurial efficiency between the central, eastern and western regions is gradually narrow; Factors such as social capital, economic development level and foreign direct investment also have a positive impact on entrepreneurial efficiency. Finally, this paper also puts forward some suggestions on improv-ing the efficiency of entrepreneurship from the perspectives of upgrading science and technology financial services, developing science and technology financial innovation and entrepreneurial environment.

With the development of the times, the competition between enterprises and enterprises in the traditional mode has been transformed into competition between the supply chain and other supply chains, and enterprises are in-creasingly focusing on cooperation with other companies in the supply chain. And to be able to cooperate better, organizations and organizations have to consider the cost, especially the cost of the problem after the cooperation. How to define and reduce this cost is an important factor for the organization to achieve higher returns in the supply chain. Based on this problem, this paper focuses on the definition of inter-organizational interconnection costs and its influencing factors, and conducts relevant empirical analysis.

Increasing urbanisation, poor location of urban amenities and utilities in consideration to population concentration has made many cities face environmental, land use and socio-economic challenges. This can be mitigated against through the analysis of the interactions existing between urban natural and human systems as provided for by the geospatial technology notably Remote Sensing, Geographical Information Systems (GIS) and Photogrammetry. This has made geospatial technology gain primacy in the urban studies and literature on the utility of geospatial techniques in the analysis and modelling of urban morphology has grown over the years. This paper therefore, anchors an understanding on the urban morphology and the role of geospatial techniques in studying the same.

Using 2007-2017, securities regulatory commission announced on the administrative penalty, penalty and certified public accountant firm in the audit failure penalty as the research sample, respectively, from the audit failure of violating the frequency of the auditing standards, registered public accounting firm scale and the relationship between the financial fraud and audit failure three aspects to discusses the reasons of audit failure. It is found that “audit evidence” and “verification” account for a large proportion of audit failures. There is a positive correlation between the size of firms and audit quality, and the proportion of audit failures in “big firms” is low. There is no correlation between financial fraud and audit failure. , In view of the reasons for the audit failure, this paper puts forward some preventive strategies. ,

In China, the development and the wide usage of mobile Internet and intelligent terminal devices have exerted a huge impact on people’s reading patterns. Reading has entered the “Fragmentation Era”, and “Fragmented Reading” has become the major pattern of reading.This paper expounds the advantages and disadvantages of fragmented reading and the influence of the major trend of fragmented reading on college students’ reading and what role should university library play and what reading service should it provide in the age of fragmented reading.

Bangladesh is a developing country where 75% of total population lives in rural area. Subsequently they have poor healthcare access as 26% of rural professionals remain vacant and nearly 40%, absent. Although official documents indicate that 80% of the population has access to affordable essential drugs, there is plenty of evidence of a scarcity of essential drugs in government healthcare facilities. Nearly 45% rural people take medical assessment from unqualified health workers including medical assistants, mid-wives, village doctors, community health workers in comparison to that by qualified medical graduates (only 10%-20%). More than 75% women having complications sought treatment from an unqualified provider. These are mostly because concern over medical costs, and pronounced socioeconomic disparities found for care-seeking behavior in both urban and rural Bangladesh. However, the government’s expenditure on health is the third largest in the country, after education and defense. Diabetes is a complicated chronic disease; non-compliant patients are in a risk of moderate to severe complications, to much extent unexplored to maximum people of Bangladesh. Annually diabetes is responsible for 5% of all deaths globally, and its prevalence is increasing steadily. As reported by International Diabetes Federation (IDF), approximately 75–80% of people with diabetes die due to cardiovascular complications.

Nearly 80% of people with diabetes live in low- and middle-income countries. It increases healthcare expenditure and imposes a huge economic burden on the healthcare systems. The International Diabetes Federation estimated more than 7 million people with diabetes in Bangladesh and almost an equal number with unexplored diabetes. This number is estimated to double by 2025. It is a costly condition and may cause stroke, heart attack, chronic kidney diseases, neuropathy, visual impairment and amputations.
