Analysis of Chinese Tourists' Expectations and Satisfaction with Thai Tourism
Authors: Zhang Taolin 
Published: April 2022

With the development of economy, more and more Chinese tourists choose Thailand as their tourism destination, which
is both an opportunity and a challenge for the development of tourism in Thailand. Under this background, it is meaningful to
explore and analyze the tourism expectations and satisfaction of Chinese tourists after their on-site experience in Thailand.
On the basis of previous studies, this study compares the expected value of different tourism factors with the actual experience
satisfaction model, combines the results of the questionnaire survey, carries out data analysis with the help of software, verifies the
research hypothesis and draws conclusions. The study finds that Chinese tourists' satisfaction in Thailand is highly correlated with
the expectations of various tourism factors, and both of them are influenced by the differences of Chinese tourists' demographic
information. At the same time, the overall satisfaction is affected by various specific satisfaction factors, showing a linear additive
relationship. Finally, this study analyses the conclusions and problems found, and puts forward some countermeasures and
suggestions based on Thailand's relevant policies, economic and cultural status, to provide a suggestion for the sustainable and
healthy development of Thailand's tourism market to China.

No Brasil o modal rodoviário é o que possui a maior participação na matriz de transporte. O enfoque dessa pesquisa foi a Rua Bonaire, no município de Açailândia-MA, por ter conexão com a rodoviária e a zona central do município em questão. O objetivo do presente trabalho foi classificar o estado de qualidade de um trecho dessa rua, por meio da verificação dos parâmetros de irregularidade longitudinal através de uma metodologia prática, moderna e eficiente, empregando um equipamento MERLIN modificado com uma trena a laser. Os dados de medição foram analisados conforme a metodologia de Cundill, ou seja, através de um histograma de frequência, onde os dados foram marcados de acordo com a depreciação do trecho ou elevação do trecho. Para isso foram realizadas aferições em um trecho de 200 metros com o MERLIN modificado, calculando os parâmetros de: Índice de Irregularidade Internacional (IRI) e o Quociente de Irregularidade (QI) destes trechos analisados. Determinou-se com este trabalho que o conceito da condição de serventia da Rua Bonaire é péssimo e que as modificações feitas no MERLIN tradicional, tornaram o processo de coleta de dados mais prático e eficiente, facilitando assim o cálculo do IRI e QI. Por fim, através deste estudo, diversas oportunidades serão criadas acerca de futuras pesquisas sobre as condições de rodagens de outras vias, principalmente devido ao salto técnico que foi obtido do equipamento MERLIN tradicional para o MERLIN confeccionado neste trabalho.

PICO question
In adult horses with secondary sinusitis caused by dental disease, is computed tomography more accurate than radiography for the identification of apical dental pathology?

Clinical bottom line
Category of research question
Diagnosis
The number and type of study designs reviewed
The literature search identified four papers that were critically reviewed. The publications consist of two retrospective case-controlled studies, one clinical study and one descriptive study
Strength of evidence
Weak
Outcomes reported
Four studies reported the sensitivity of computed tomography (CT) for the diagnosis of apical dental pathology in horses presented for evaluation of clinical signs of sinus disease with histopathological evidence of apical dental pathology. All studies reported the radiographic changes present in these horses or used absence of definitive radiographic changes consistent with apical dental disease as a reason to undertake further CT evaluation. All four papers found that CT identified teeth with apical pathology that radiography had not
Conclusion
CT is more accurate than radiography for the diagnosis of equine maxillary apical dental pathology; however, clear guidelines on the CT changes associated with apical dental pathology are required. Loss of the lamina dura, infundibular changes or pulpal gas as singular findings on CT imaging can be seen in teeth with no underlying histopathological evidence of apical disease, and in maxillary teeth imaged in horses without clinical signs of maxillary cheek tooth pathology

How to apply this evidence in practice
The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.

Modeling of forest fires based on the Bayesian forecast model and geoinformation technologies
Authors: Barabash Oleg , Bandurka Olena 
Published: April 2022

Today, a variety of information about forest ecosystems can be obtained using remote sensing methods. The use of space data for forest monitoring is cost-effective because it allows you to quickly obtain the objective information needed by foresters to solve practical problems. Satellite data provide wide coverage of forest lands, high accuracy of results, as well as high frequency of data obtained. Space images of the Ovruch district of the Zhytomyr region of Ukraine in the summer of 2020 were selected for the study. Determination of breed composition was carried out by the methods of controlled classification, namely the Bayesian classifier. It was found that 70 % of forests are pine, less aspen, hornbeam, birch, alder and ash tree species. According to statistics, during 2000-2020, 51.4 thousand hectares of forest plantations in Ukraine were damaged and destroyed by forest fires. Therefore, objective and timely information on the consequences of fires is needed to solve a wide range of applied problems of forestry. An important task in assessing the environmental and economic damage caused to forestry as a result of forest fires is to determine the area of damaged forests. The paper considers technologies for determining the area of the forest where the fire took place, using space images of the Landsat 8 satellite. The normalized NBR fire index before and after the fire and the DNBR index are used to identify areas burned by fire and impression levels. To predict forest fires, a mathematical model based on Bayes' theorem was created and a thematic map with fire hazard classes on a quarterly basis was created. To check the accuracy of the results of the created forecast model, the thematic map was combined with a layer of defined fire areas. This software product is quite flexible and versatile, it can be easily adapted for use not only to identify burned forest lands, but also for other areas.
Outcomes Following Total Hip Arthroplasty for Osteonecrosis of the Femoral Head in Patients on Hemodialysis
Authors: Hoggard Timothy M. , Chen Dennis Q. , Quinlan Nicole D. , Bell Joshua E. , Werner Brian C. , Cui Quanjun 
Published: April 2022

Background:
Osteonecrosis of the femoral head (ONFH) is a potentially debilitating condition, often requiring total hip arthroplasty (THA). Patients on hemodialysis (HD) are at increased risk for complications after THA for osteoarthritis, however there is limited information on outcomes of THA for ONFH in patients on HD. With increasing prevalence of chronic kidney disease (CKD) requiring HD, studies are needed to characterize the risk of complications in these patients. Therefore, the purpose of this study was to evaluate HD as a potential risk factor for complication after THA in patients with ONFH on HD.

Methods:
Patients on HD with ONFH who underwent THA with at least 2 years of follow-up were identified using a combination of ICD-9 and CPT codes in a national insurance database. A 10:1 matched control cohort of patients with ONFH not on HD was created for comparison. A logistic regression analysis was used to evaluate rates of death, hospital readmission, emergency room (ER) visit, infection, revision, and dislocation between cohorts. Differences in hospital charges, reimbursement, and length of stay between the two groups were also assessed.

Results:
One thousand one hundred thirty-seven patients on HD who underwent THA for ONFH were compared to a matched control cohort of 11,182 non-HD patients who underwent THA for ONFH. Patients on HD experienced higher rates of death (HD 4.1%, non-HD 0.9%; odds ratio [OR] 3.35, p < 0.01), hospital readmission (HD 16.1%, non-HD 5.9%; OR 2.69, p < 0.01) and ER visit (HD 10.4%, non-HD 7.4% OR 1.5, p < 0.01). Hemodialysis was not associated with higher risk of infection, revision, or dislocation, but was associated with significantly higher charges (p < 0.01), reimbursement (p < 0.01), and hospital length of stay (p < 0.01).

Conclusions:
While patients on HD do not have increased risk of implant-related complications, they are at increased risk of developing medical complications following THA for ONFH and subsequently may require more resources. Orthopedic surgeons and nephrologists should be cognizant of the increased risk in this population to provide appropriate preoperative counseling and enhanced perioperative medical management.

Effect of Cutter Shape on the Resistance of PDC Cutters Against Tip Impacts
Authors: Wei Jiusen , Liu Wei , Gao Deli 
Published: April 2022

Summary
Under harsh downhole conditions, the quasibrittle characteristics of polycrystalline diamond compact (PDC) cutters are a serious drawback, which readily causes the cutters’ premature failure under impact loads. Innovating 3D cutter shapes is an effective solution for optimizing the cutter’s interaction with the rock and improving the impact resistance of PDC cutters. However, the mechanism of how the cutter shape affects the impact resistance is rarely studied or published.
In this work, the quantitative energy analysis method was used to create a cutter-impactor interaction model where the interaction was assumed as a process of energy transformation and dissipation. To validate the developed mathematical model, cutters with various geometric shapes were designed and evaluated by laboratory progressive drop tests (PDTs) as well as field trials. The investigations revealed that the predictions of the mathematical model were consistent with both the laboratory results and the field feedback when the relative sharpness evaluation parameter was less than 0.3. The tip impact resistance was positively related to the relative sharpness evaluation parameter. However, when the S is more than 0.3, the cutter shape will present poor tip impact resistance and is not recommended to fabricate in terms of tip impact resistance. In these cases, the protruding tip did not have sufficient support and caused a premature impact failure under the tangential forces. The developed cutter-impactor interaction model filled the technical void of current studies on shaped cutters, which could guide the innovations of the cutter shapes to obtain better tip impact resistance.
Field testing indicated that PDC cutters suffered both front and tip impacts under downhole. If the cutter shape matched with the front or tip impact form, the cutters would fulfill satisfactory field performance. Field testing also indicated that the vulnerability of PDC bit under impact loads was strongly related to the regions of the cutting structure. The bit’s impact resistance could be greatly improved by placing the cutters with the right cutter shape at the right regions of the cutting structure. For example, the rhino-horned cutters were placed at the nose and shoulder to fight against the front impacts but were not suggested to deploy at the regions near the gauge because of poor tip impact resistance.
Asymmetrical attention to gambling-related stimuli and pupillary dilation in response to wins and losses in problem gamblers
Authors: Shigemune Yayoi , Midorikawa Akira 
Published: April 2022

Abstract
Gambling disorder and problem gambling are characterized by persistent and repetitive problematic gambling behavior. Attentional bias toward gambling-related stimuli such as casino chips, dice, roulette, etc. have been observed in problem gamblers, but it remains unclear whether stimuli in gambling tasks elicit greater attention and pupillary responses in problem gamblers. To address this issue, we administrated problem and non-problem gamblers a gambling task accompanied by eye-tracking measurements, in which the participants were required to choose one of the paired pictures to receive monetary rewards and avoid punishments. Concerning attentional allocation, problem gamblers showed a greater attentional preference for the right-hand pictures in the decision and feedback phases, and compared to non-problem gamblers, problem gamblers’ attention was particularly high around the center. Concerning pupillary dynamics, pupillary dilation in response to rewards and punishments was observed only in problem gamblers. Accordingly, asymmetrical allocation of attention by problem gamblers may reflect greater concentration on the gambling task, and pupillary dynamics in problem gamblers may reflect hypersensitivity to wins and losses.
Advanced Optimization Models for Bandwidth Provisioning and Routing in Fixed Microwave Backhaul Networks
Authors: Mehadji Djamil , Kaddour Mejdi 
Published: April 2022

Abstract
This paper addresses the problem of determining bandwidth allocation and traffic routes in fixed microwave networks such that overall bandwidth cost is minimized while traffic demands are satisfied with a required reliability level. These networks exhibit high variability in link throughput as modulations schemes are adapted dynamically to ensure acceptable bit-error rate at the receivers according to external conditions such as the weather. First, we formulate an optimal optimization approach based on mixed-integer linear programming, which is subsequently reinforced by inserting problem-specific valid inequalities based on global network capacity and feasible bandwidth/modulation combinations. Then, we introduce a Lagrangian-based heuristic that provides near optimal solutions while reducing drastically the computation time. In comparison to previous work, our experimental results show that our approaches are capable to solve large real-world network instances in an effective manner. Furthermore, the results evaluate the impact of reliability and transported traffic demands on bandwidth cost.

Published: April 2022

Abstract
Background: Diuretic use in acute kidney injury (AKI) is debatable. Contrasting outcomes have been reported regarding its efficacy in AKI. Sequential nephron blockade (SNB) has never been studied in a diverse ICU population admitted with AKI.Methods: Consecutive patients admitted to medical ICU with oliguric AKI over 1-year period were recruited. SNB as a diuretic strategy was administered. Responders (R) and non-responders (NR) were compared. Demographic data, clinical profile, treatment and outcomes were compared between the groups using t-test and Chi-square test as appropriate. Predictors of mortality were explored using bivariate and multivariate logistic regression analysis and expressed as Odds ratio (OR) with 95% confidence interval (CI). Results: Of the 331 ICU patients admitted with AKI, 312 patients received SNB. The mean (SD) age was 64.14±14·79 years with male preponderance (196:116). Admission SOFA score was significantly (p<0·001) higher (9.6±3.8) in non-responders than responders (6·3±3.6). Overall, 80.13% patients were responders and 19.6% patients received RRT. Significant difference (p<0·001) for diuretic response and dialysis were seen with pre-existing diabetes, higher KDIGO stage and SOFA score (>9) at ICU admission, sepsis, shock, mechanical ventilation, positive fluid balance, lengthy ICU stay and mortality. On multivariate logistic regression analysis, SOFA score >9(OR 4.50; 95%CI 2.30-8.80), negative diuretic response (OR 0.45; 95%CI 0.34-0.59), RRT need (OR 1.78; 95%CI 1.25-2.19) and a higher positive fluid balance (OR 2.82; 95%CI 1.76-3.89) were independently associated with death. Conclusions: SNB in oliguric AKI patients resulted in lesser need for dialysis and better outcomes. A negative response, need for dialysis and a higher positive fluid balance were independently associated with mortality.
Is volume-controlled ventilation superior to pressure-controlled ventilation in patients with severe brain lesions? A pilot study
Authors: Roth Christian , Laakmann Jan-David , Gehling Markus 
Published: April 2022

Abstract
Background: Is there an advantage of volume-controlled ventilation (VCV) over pressure-controlled ventilation (PCV) in the management of patients with intracranial pathology? Methods: Between August 2015 and March 2017, a prospective monocentric crossover trial was performed in neurocritical care patients with invasive ICP monitoring and mechanically controlled ventilation. Two different ventilation modes (VCV and PCV) were applied during a night shift for two hours in each intervention group. The primary end point was the dispersion of ICP and CPP. Secondary endpoints included the differences between mean ICP and CPP, and the incidence of critical ICP or CPP values (ICP > 20 mmHg, CPP < 50 mmHg).Results: Data from a total of 32 patients were analysed. VCV was associated with increased dispersion of maximum ventilation pressure. PCV resulted in elevated dispersion of minute volume and tidal volume. Differences in the dispersion of ventilation parameters did not result in increased dispersion of ICP and CPP. However, we found a significant decrease in mean CPP values with VCV (76.2 mmHg versus 80.1 mmHg; p = 0.03). Furthermore, VCV was associated with a significantly increased rate of adverse events with a CPP < 50 mmHg (VCV: 4.4% versus PCV: 2.6%, p = 0.03). Conclusions: In our study population, VCV was not superior to PCV with regard to ICP and CPP. Moreover, our data suggest that PCV may lead to higher CPP values and may reduce the rate of decreased CPP in patients with acute brain diseases.

Managing clustering effects and learning effects in the design and analysis of randomised surgical trials: A review of existing guidance
Authors: Conroy Elizabeth Jane , Blazeby Jane M , Burnside Girvan , Cook Jonathan A , Gamble Carrol 
Published: April 2022

Abstract
BackgroundThe complexities associated with delivering randomised surgical trials, such as clustering effects, by centre or surgeon, and surgical learning, is well known. Despite this, approaches used to manage these complexities, and opinions on these, vary. Guidance documents have been developed to support clinical trial design and reporting. This work aimed to identify and examine existing guidance and consider their relevance to clustering effects and learning curves within surgical trials.MethodsA review of existing guidelines, developed to inform the design and analysis of randomised controlled trials, is undertaken. Guidelines were identified using an electronic search, within the Equator Network, and by a targeted search those endorsed by leading UK funding bodies, regulators, and medical journals. Eligible documents were compared against pre-specified key criteria to identify gaps or inconsistencies in recommendations. ResultsTwenty-eight documents were eligible (12: Equator Network; 16 targeted search). Twice the number of guidance documents targeted design (n/N=20/28, 71%) than analysis (n/N=10/28, 36%). Managing clustering by centre through design was well documented. Clustering by surgeon had less coverage and contained some inconsistencies. Managing the surgical learning curve, or changes in delivery over time, through design was contained within several documents (n/N=8/28, 29%), of which one provided guidance on reporting this and restricted to early phase studies only. Methods to analyse clustering effects and learning were provided in five and four documents respectively. (N=28)ConclusionsTo our knowledge this is the first review as to the extent to which existing guidance for designing and analysing randomised surgical trials covers the management of clustering, by centre or surgeon, and the surgical learning curve. Twice the number of identified documents targeted design aspects than analysis. Most notably, no single document exists for use when designing these studies, which may lead to inconsistencies in practice. The development of a single document, with agreed principles to guide trial design and analysis across a range of realistic clinical scenarios, is needed.RegistrationNot applicable.
