Space tourism flow generated from social media data.

The data is for empirical studies derived from a related research article about space tourism [1], which is a conceptual article with a different aim of economic measurement scale. Most space tourism research is conceptual because data from the nascent industry is limited [2]. Thus this data is constrictive for conducting empirical studies to contribute to quantitative analysis in space tourism [3]. Data from this study were collected by recruiting 361 respondents through snowball and convenient sampling targeted to samples interested in space tourism; 339 responses were adopted after the valid screening of missing data or data bias [4]. Targeted groups of potential space tourism customers were investigated to collect data through a designed questionnaire on the platform, Wenjuanxing, with a majority population database providing functions equivalent to Amazon Mechanical Turk [2]. The reliability and validity of all constructs showed that the questionnaire was proper for measurement [3]. Data analysis applied the structural equation model with Mplus to examine the CFA model and research hypothesis. Structural equation modeling was used to conduct the hypotheses test and model fitness through the statistical tool Mplus. Results imply that the data is suitable for conducting replication studies. To enlighten space tourism emergence studies, this data shows its importance for further research models [5].

OBJECTIVES: Hip arthroplasty is the most important surgical method for the treatment of hip fractures and necrosis in the femoral head. Limb function recovery is an important criterion to reflect the efficacy of surgery and the quality for life of patients. Postoperative rehabilitation exercises are crucial for limb function recovery. Otago exercise programme (OEP) is a safe, effective, practical, and economical rehabilitation exercise, which has been proven to prevent falls, improve limb function and walking ability, and lower limb strength. This study aims to explore the effect of OEP on limb function rehabilitation in elderly patients with hip arthroplasty for femoral neck fractures. METHODS: A total of 77 elderly patients with hip arthroplasty for femoral neck fractures who met the criteria for inclusion and exclusion were enrolled for this study. They were randomly divided into a control group ( n =39) and an intervention group ( n =38). The control group was given routine rehabilitation training, and the intervention group performed OEP on the basis of the control group. Time get up and go test (TGUT), five times sit to stand test (FTSST), 10-meter walking test (10MWT), Harris Hip Score (HHS), Daily Activity Scale (Barthel index), and the Mos 36-Item Short Form Health Survey (SF-36) were used before the intervention, at discharge, and the 12th week after discharge. RESULTS: Before the intervention, there were no differences in TGUT, FTSST, 10MWT, HHS score, Barthel index, and SF-36 score between the 2 groups (all P >0.05). At the discharge after the intervention, there was no difference in TGUT between the 2 groups ( P >0.05), but the FTSST and 10MWT in the control group were longer than those in the intervention group (both P <0.05), and the HHS score, Barthel index, and SF-36 score in the control group were lower than those in the intervention group ( P <0.05). At the 12th week after discharge, TGUT, FTSST, 10MWT, HHS score, Barthel index, and SF-36 score in the intervention group were better than those in the control group ( P <0.05). CONCLUSIONS: OEP can effectively promote limb stability and hip function recovery in elderly patients with hip arthroplasty for femoral neck fractures, improve daily mobility and quality of life, and it is suitable for clinical application.

Hospitality education evolution observed in online learning dataset.

The research article "Realtime Online Courses Mutated amid the COVID-19 Pandemic: Empirical Study in Hospitality Program" aims to explore the education evolution amid the pandemic [1]. Data were collected by recruiting 956 respondents; 926 responses were adopted after the valid screening through a cooperative survey company. A random sampling of targeted groups was required when outsourcing the data collection to the survey company Wenjuanxing, a platform with a majority population database providing functions equivalent to Amazon Mechanical Turk [2]. We asked the company to deliver the designed questionnaire to teachers and students in hospitality programs. The reliability and validity of all constructs showed that the questionnaire is proper for measurement [3]. Data analysis applied the structural equation model with Mplus to examine the CFA model and research hypothesis. Structural equation modeling was applied to conduct the hypotheses test and model fitness through the statistical tool Mplus. Results imply that the data is suitable for conducting replication studies.

Realtime online courses mutated amid the COVID-19 pandemic: Empirical study in hospitality program.

Real-time online courses (RTOCs), a new online learning mode, have been developed because of a longitudinal suspension of classes amid the COVID-19 pandemic worldwide. We explore an information model to review the learning process and outcomes of RTOCs, which conducted educational activities via social media. Results show that social media can be a potent mediation factor with the moderation of structural differentiation to facilitate online learning outcomes. Conclusions imply that the life-changing impact of COVID-19 has caused an evolutionary online education mode that can be hybridized with face-to-face education and massive open online courses to flourish education approaches and pedagogies.

Manual lymphatic drainage for lymphedema in patients after breast cancer surgery: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Studies have shown that manual lymphatic drainage (MLD) has a beneficial effect on lymphedema related to breast cancer surgery. However, whether MLD reduces the risk of lymphedema is still debated. The purpose of this systematic review and meta-analysis was to summarize the current evidence to assess the effectiveness of MLD in preventing and treating lymphedema in patients after breast cancer surgery. METHODS: From inception to May 2019, PubMed, EMBASE, and Cochrane Library databases were systematically searched without language restriction. We included randomized controlled trials (RCTs) that compared the treatment and prevention effect of MLD with a control group on lymphedema in breast cancer patients. A random-effects model was used for all analyses. RESULTS: A total of 17 RCTs involving 1911 patients were included. A meta-analysis of 8 RCTs, including 338 patients, revealed that MLD did not significantly reduce lymphedema compared with the control group (standardized mean difference (SMD): -0.09, 95% confidence interval (CI): [-0.85 to 0.67]). Subgroup analysis was basically consistent with the main analysis according to the research region, the publication year, the sample size, the type of surgery, the statistical analysis method, the mean age, and the intervention time. However, we found that MLD could significantly reduce lymphedema in patients under the age of 60 years (SMD: -1.77, 95% CI: [-2.23 to -1.31]) and an intervention time of 1 month (SMD: -1.77, 95% CI: [-2.23 to -1.30]). Meanwhile, 4 RCTs including, 1364 patients, revealed that MLD could not significantly prevent the risk of lymphedema (risk ratio (RR): 0.61, 95% CI: [0.29-1.26]) for patients having breast cancer surgery. CONCLUSIONS: Overall, this meta-analysis of 12 RCTs showed that MLD cannot significantly reduce or prevent lymphedema in patients after breast cancer surgery. However, well-designed RCTs with a larger sample size are required, especially in patients under the age of 60 years or an intervention time of 1 month.

Improvements in dental care using a new mobile app with cloud services.

BACKGROUND/PURPOSE: Traditional dental care, which includes long-term oral hygiene maintenance and scheduled dental appointments, requires effective communication between dentists and patients. In this study, a new system was designed to provide a platform for direct communication between dentists and patients. METHODS: A new mobile app, Dental Calendar, combined with cloud services specific for dental care was created by a team constituted by dentists, computer scientists, and service scientists. This new system would remind patients about every scheduled appointment, and help them take pictures of their own oral cavity parts that require dental treatment and send them to dentists along with a symptom description. Dentists, by contrast, could confirm or change appointments easily and provide professional advice to their patients immediately. In this study, 26 dentists and 32 patients were evaluated by a questionnaire containing eight dental-service items before and after using this system. Paired sample t test was used for statistical analysis. RESULTS: After using the Dental Calendar combined with cloud services, dentists were able to improve appointment arrangements significantly, taking care of the patients with sudden worse prosthesis (p < 0.05). Patients also achieved significant improvement in appointment reminder systems, rearrangement of appointments in case of sudden worse prosthesis, and establishment of a direct relationship with dentists (p < 0.05). CONCLUSION: Our new mobile app, Dental Calendar, in combination with cloud services, provides efficient service to both dentists and patients, and helps establish a better relationship between them. It also helps dentists to arrange appointments for patients with sudden worsening of prosthesis function.
