ABSTRACT
Purpose: This paper presents a comprehensive study using bibliometric and social network analysis (SNA) to depict the academic community, research hotspots and the correlation between research performance and social network measurements within Library Hi Tech. Design/methodology/approach: Publications from Library Hi Tech between 2010 and 2022 are reviewed and analysed through coauthorship analysis, co-occurrence analysis, SNA and the Spearman rank correlation test. Findings: The annual number of publications in Library Hi Tech increased from 2016 to 2022, indicating that this research has gradually gained global attention. The USA and China are the most significant contributors to the relevant publications. Scholars in this field mainly engage in small-scale cooperation. Academic libraries, digital libraries, libraries, information technology and COVID-19 were hot topics during the study period. In light of the COVID-19 pandemic, there was a marked increase in research on healthcare. Academic interest in the internet of Things and social media has proliferated recently and may soon attract more attention. Spearman rank correlation analysis shows that research performance (i.e. publication count and citation count) is significantly and positively correlated with social network measurements (i.e. degree centrality, betweenness centrality, closeness centrality and eigenvector centrality) in studies of Library Hi Tech. Originality/value: This paper reveals a systematic picture of the research landscape of Library Hi Tech and provides a potential guide for future research. The relationship between scientific research performance and social network measurements can be objectively identified based on statistical knowledge. © 2023, Emerald Publishing Limited.
ABSTRACT
During the COVID-19 outbreak, many healthcare workers (HCWs) have been infected because they failed to comply with the correct process of donning and doffing personal protective equipment (PPE). Based on this, we develop a gesture-controlled system that not only can train HCWs but also can give HCWs real-time guidance during the process of donning and doffing PPE. It can effectively prevent the infection of HCWs. We first use the hand detection algorithm to locate the position of the HCWs, helping them to enter the proper area. Then they can use our gesture recognition algorithm to control the playback of the videos which guides them in donning and doffing PPE. We verify the effectiveness of the system through a series of experiments. The results show the great value of our system in the protection of HCWs. © 2022 IEEE.
ABSTRACT
Objective: Exploring the disinfection effect of high-pressure carbon dioxide (HPCD) on human coronavirus 229E (hCoV-229E). Methods: The human coronavirus 229E (hCoV-229E) was treated by HPCD at different temperatures (10, 25, and 37 ℃) and pressures (6.3 and 10 MPa) for different time (15 and 30 min). Result: Compared with the control groups under the corresponding temperatures, the virus titer in 50 mL tube treated with HPCD at 10 ℃ and 6.3 MPa for 30 min was significantly decreased (P<0.05). The virus titer was also significantly reduced after treatment with HPCD at 37 ℃ and 10 MPa for 15 min (P<0.01). Moreover, the virus titers inoculated on the surfaces of salmon meat, shrimp shell, and polyethylene packing materials were all significantly decreased after HPCD treatment at 37 ℃ and 10 MPa for 15 min as compared with the corresponding control groups (P<0.05). Conclusion: HPCD treatment at 37 ℃ and 10 MPa for 15 minutes could effectively disinfect hCoV-229E on the surface of food (salmon meat and shrimp shell) and polyethylene packaging materials. © 2023, Editorial Department of Science and Technology of Food Science.

ABSTRACT
-This research aimed to evaluate the current attitudes of Chinese travelers. We conducted a survey of Chinese tourists traveling in China's coastal area under the national Zero Covid-19 Policy. The surveys were conducted during two periods: the first was from September 28-October 7, 2022;the second from October 29-November 16, 2022. Both took place before China announced national Covid-19 tolerance in December 2022. All participants were interviewed face-to-face using a questionnaire created by our research team. The results of correspondence analyses revealed the following. Chinese travelers were somewhat indifferent about traveling during the Covid-19 restrictions, especially groups 20–29 and 30–39 years old. On the other hand, the Covid-19 restrictions appeared to have less effect on those under 20 years old. In imagining the after-Covid-19 era, although those 30–39 were willing to travel to Japan, those 20–29 were neutral about the idea. Although familiarity with the Tohoku area, especially Iwate Prefecture, was very low among Chinese travelers according to the results, we assume their willingness to visit Miyako City in Iwate Prefecture is rather high. To promote Chinese interest in the tourist resources of Miyako City, we assume that it would be better to use popular Chinese SNS systems such as Weibo, WeChat, and TikTok, rather than popular Japanese SNS systems. © 2023, World Scientific and Engineering Academy and Society.

ABSTRACT
Since the outbreak of a new round of COVID-19 in Xi'an on December 9, 2021, the response capability of the city's and even the province's health system to major public health emergencies has been severely tested and challenged. Faced with the rapid spread of the Delta strain and its multiple hidden transmission chains, The First Affiliated Hospital of Xi'an Jiaotong University, as the largest comprehensive tertiary hospital in Northwest China, has successfully applied the 4R crisis management theory to prevent the pandemic spread and continue the clinic work as well. Balancing of epidemic prevention and medical service with scientific, orderly and standardized procedures has been achieved. Hence, we have contributed to the "The First Affiliated Hospital of Xi'an Jiaotong University model" for controlling the epidemic and restoring normal production and life as soon as possible under the guidance and command of the National Health Commission and provincial and municipal health administrative institutions at all levels. The First Affiliated Hospital of Xi'an Jiaotong University has improved the present management system and enhanced its management level amid epidemic prevention and control. This paper aims to provide new epidemic prevention experience under the changeable environment by explaining and summarizing our theoretical basis, operation mode and practical effects of our management system.
ABSTRACT
Background: With the unprecedented morbidity and mortality associated with the COVID-19 pandemic, vaccine against COVID-19 has been more and more popularized in general population. However, the safety of COVID-19 vaccine injection in patients with malignant tumors, such as colorectal cancer (CRC), remains unclear. Methods: During January 2021 and January 2022, 148 CRC patients treated in the department of colorectal surgery in the Sixth Affiliated Hospital of Sun Yat-sen University were enrolled in this cohort. The clinical data and COVID-19 vaccine injection outcome data was collected and analyzed retrospectively. Patients who received at least one dose of COVID-19 vaccine injection were set as an observation group and those who did not get any vaccine injection were set as a control group. The median follow-up time was 8.0 months, vaccine-related adverse events (VRAEs) were collected by questionnaire. The disease progression status of CRC was also compared between the two groups. Results: Eighty-three CRC (male: female 44:39) patients enrolled in this study have got at least one dose of COVID-19 vaccine injection, with a median follow-up time of 8.0 (2.0-13.0) months and no VRAEs reported. Among the vaccinated patients, 51 patients were injected with inactivated vaccine (Sinovac Life Sciences Co., Ltd.), 10 patients were vaccinated with inactivated vaccine (Beijing Institute of Biological Products Co., Ltd.), others were injected another inactivated vaccine (Chengdu Institute of Biological Products Co., Ltd.). The reasons of the 65 patients (male: female 36:29) who did not injected COVID-19 vaccine including: 53 patients had a concern that vaccination will affect the progress of CRC, 8 patients had a concern of old age to get vaccinated and 4 patients did not give any reason. As for disease progression, 14 patients in the observation group had tumor recurrence or progression, while 8 patients in control group reported tumor recurrence or progression, with a median follow-up time of 8.0 (2.0-13.0) months. There was no significant difference in short-term disease progression between the observation group and the control group (P = 0.439). Conclusions: Under the background of COVID-19 pandemic and vaccination of general population, it might be necessary for the patients with malignant disease, such as CRC, to get vaccinated due to whose weaken immune system. COVID-19 vaccine injection is safe for CRC patients and COVID-19 vaccination would not affect the patients' prognosis.
ABSTRACT
Background: The coronavirus disease 2019 (COVID-19) struck China from late 2019 before its rapid spread across the country. Tianjin, as one of the largest cites in the north of China, reported a number of confirmed COVID-19 cases shortly after its outbreak in Wuhan province. After the pandemic was brought under control in May, strict control measures were put in place as routine to prevent cross-infection, which contributed to the change in vascular access practice. Therefore, a retrospective study was conducted to evaluate the impact of COVID-19 on vascular access in non-hot-spot region, north China. Methods: In this multicenter cross-sectional study, vascular access data was collected from the hemodialysis patients treated at 52 hospitals in Tianjin from 1 January to 14 Decmeber 2020. The practice of vascular access was estimated during the outbreak of Covid-19 since late 2019. Results: Among the 6885 hemodialysis patients included, 4719 arteriovenous fistulas were identified as the main type of vascular access, accounting for 68.54%. While 2114 patients (30.7%) had tunneled cuffed catheter. The proportion of arteriovenous graft reached as low as 1%. Overall, 1819 vascular access sites were placed in the patients newly diagnosed with uremia, of whom 990 (54.5%) underwent catheter insertion, 811 (44.6%) underwent AVF creation, and only 18 AVGs were created. In addition, the proportion of vascular access sites performed in general hospitals was 88.6%. During the period, tempt catheter insertion was carried out for 1371 (75%) incident hemodialysis patients. Due to stenosis of AVF, percutaneous transluminal angioplasty was conducted for 83 patients. However, no patient got diagnosed with Covid-19. Conclusions: Catheter was the primary vascular access type during the pandemic and the rate of catheter use for incident patients was high. Most of vascular access creation was carried out in general hospitals while the numbers of AVG and PTA were relatively low.
ABSTRACT
BACKGROUND: The impact of the coronavirus disease 2019 (COVID-19) outbreak shut down most conferences. To minimalize the influence, virtual meetings sprang up subsequently. International Microsurgery Club (IMC), as one of the largest professionals-only online microsurgery education groups worldwide, began to host regular weekend webinars during the pandemic to fill the knowledge gap. This study aims to discuss how webinars have fundamentally changed the way knowledge is delivered and exchanged. METHODS: From February 29, 2020 to March 14, 2021, 103 IMC webinars were reviewed and analyzed in detail to determine the use, benefit, and effect. A comparison between webinars hosted by the different societies was made as well. A questionnaire survey focusing on attendees' behavior, attitude, and using habit about webinars was also made. RESULTS: As for the 103 IMC webinar events, the peak participants were 112.3 people in average. The members requesting to join IMC abruptly increased during the pandemic, and the group activity increased dramatically. From the questionnaire (n = 68), the satisfaction level was high (8.88 ± 1.18/10). The respondents were most satisfied with the good quality of the speakers (73.5%). Not only hosts our webinar series but IMC also serves as the platform that welcomes webinars from other societies to share their information. In September 2020, International Microsurgery Webinar League was established via the significant webinar hosts, with more than 300 recorded webinar talks connected successfully. CONCLUSION: As the knowledge revolution driven by COVID-19 will continue, IMC will keep playing an essential role in exploring new and emerging opportunities to improve knowledge dissemination worldwide beyond the space-time boundary.

In China, more than 80,000 people have been diagnosed with COVID-19, and more than 3,000 people have lost their lives. It seems that there will be more deaths since the epidemic is not over. All the Chinese provinces have reported the COVID-19 cases. This chapter aims to explore the trend of COVID-19 treatment efficiency in Chinese provinces using the data released daily by China Center for Disease Control and Prevention. Since China Center for Disease Control and Prevention began to release data daily from January 24 to March 12, we have more than 40 groups of daily data for 31 provinces in China mainland. In the calculation, we take the daily data of each province as a sample and then we have more than 1,200 samples in this study. We use additive two-stage data envelopment analysis as an efficiency evaluation tool to calculate the COVID-19 treatment efficiency. In our framework, the first stage is to understand the infection rate and the second stage is to evaluate the treatment efficiency. In the first stage for the tth day, we use total population (p) and number of people infected in the previous day (inft21 ) as the inputs and cumulative number of people infected in the current day (inft ) as the output. In the second stage for the tth day, we use cumulative number of people infected in the current day (inft) as the input and cumulative death in the current day (deatht) and cumulative recovery in the current day (recovt ) as the outputs. Some techniques on how to deal with undesirable outputs such as inft and deatht are employed in this study. After we have the infection rate and treatment efficiency for the samples more than 1,200, we analyze the COVID-19 treatment efficiency and its development trend from January 24 to March 12 in 34 regions of China from static and dynamic aspects. The results show that, on the whole, the overall efficiency and phased efficiency of COVID-19 treatment efficiency in all regions of China are relatively high, which reflects the key factor for the Chinese government to quickly control the epidemic in the short term. Relatively speaking, the average efficiency value in the infection stage (first stage) is lower than the average efficiency value in the healing stage (second stage), which shows that the focus of anti-epidemic in China should be early detection and prevention rather than treatment process. In terms of trend, the total efficiency of COVID-19 treatment in each region shows a trend of “increasing first and then decreasing.” Our analysis indicates that in the initial stage, the continuous increase of various resources leads to the rise of the total efficiency, while in the later stage, the rapid decline of the number of infected people leads to the decrease of the total efficiency. Based on the results of the efficiency analysis, this study provides corresponding management implications and policy suggestions, hoping to provide some enlightenment and suggestions for the anti-epidemic work of other countries in the severe environment where the epidemic is spreading rapidly. © 2021 by Emerald Publishing Limited.
ABSTRACT
Objective: To evaluate the efficacy and safety of fibrinolysis strategy in patients with acute ST-segment elevation myocardial infarction (STEMI) during the COVID-19 epidemic, and to provide reference value for optimization of fibrinolytic process on the premise of prevention and control of COVID-19 transmission, including self-protection of medical staff. Methods: The efficacy and safety of fibrinolysis were retrospectively analyzed in 7 patients with acute STEM, who hospitalized from February 29, 2020 to April 3, 2020 in the Department of Cardiology, Wuhan Union Hospital of Tongji Medical College, Huazhong University of Science and Technology. To optimize the fibrinolytic process on the premise of prevention and control of COVID-19 transmission, including self-protection of medical staff, a full-time medical team in charge of fibrinolysis under third-grade protection was established. The acute STEMI patients were treated immediately in a fixed and isolated area in emergency department before receiving green channel fibrinolysis. Blood samples for complete blood count, COVID-19 antibody test and nasopharyngeal swab samples for COVID-19 nucleic acid test were made before fibrinolysis, while the chest CT examination was accomplished after fibrinolysis. By comparing differences of time from the first electrocardiogram (ECG) to fibrinolysis before and after the improvement of fibrinolytic process, the effect of optimization of the fibrinolytic process was evaluated. Results: In the present study, seven patients with acute STEMI received fibrinolysis therapy, 6 of them achieved reperfusion and no bleeding was observed in all of the patients. Five out of the 7 patients were hospitalized after fibrinolysis, and the hospitalization days were 19.6 days on average. By following up to April 14, 2020, none of the 7 patients died. The first 2 patients were treated according to the routine medical procedure and the time from the first ECG to fibrinolysis were 201 and 106 minutes, respectively. After the optimization of the fibrinolytic process, the time from the first ECG to fibrinolysis of the last 5 patients were 42, 46, 51, 43 and 54 minutes, respectivelyï¼which was significantly shorter than that before optimization. Conclusions: During the COVID-19 epidemic, fibrinolysis in patients with acute STEMI is safe, effective and easy to implement. Therefore, it is recommended as the top priority for the patients with acute STEMI with indications for fibrinolysis. On the premise of prevention and control of COVID-19 transmission, including self-protection of medical staff, the duration of myocardial ischemia can be shortened by optimization of the fibrinolytic process.
