Background and Aims: The quality of recovery (QoR)-40 score has been used worldwide and validated in many surgical cohorts to assess global patient recovery. We aim to translate and culturally adapt the QoR-40 score into Hindi and test the validity and reliability of the translated version in patients undergoing cancer surgery. Methods: The translation of the QoR-40 questionnaire was based on the forward and backward translation methods. Patients filled out the translated version of the QoR-40 preoperatively, on the third postoperative day in the morning (POD3) and the evening. The reliability of the translated questionnaire was checked for internal consistency, test-retest reliability and split-half reliability. Construct validity was assessed with a correlation coefficient value between the total QoR-40 score, visual analogue scale (VAS) for pain and total length of hospital stay. Content validity was evaluated for feasibility and understanding. Results: The questionnaire was completed by 350 patients. The correlation coefficient r for repeatability was 0.21, the split-half test was 0.92, and Cronbach’s alpha was 0.82. The correlation between QoR-40 on POD3 with VAS score and length of stay was -0.35 and -0.67, respectively. The average time to complete the questionnaire was 3.8 minutes; 90% of the respondents found the translated questionnaire easy to understand, and 92% of the patients related the questions to their recovery. Conclusion: The Hindi translation of the QoR-40 questionnaire is a valid and reliable version of the original questionnaire in English to assess the QoR in Hindi-speaking patients after cancer surgery.

Abstract Background: Quality of recovery (QoR) after anesthesia is an important measure of the early postoperative health status of patients. The aim was to develop a short-form postoperative QoR score, and test its validity, reliability, responsiveness, and clinical acceptability and feasibility. Methods: Based on extensive clinical and research experience with the 40-item QoR-40, the strongest psychometrically performing items from each of the five dimensions of the QoR-40 were selected to create a short-form version, the QoR-15. This was then evaluated in 127 adult patients after general anesthesia and surgery. Results: There was good convergent validity between the QoR-15 and a global QoR visual analog scale (r = 0.68, P < 0.0005). Construct validity was supported by a negative correlation with duration of surgery (r = −0.49, P < 0.0005), time spent in the postanesthesia care unit (r = −0.41, P < 0.0005), and duration of hospital stay (r = −0.53, P < 0.0005). There was also excellent internal consistency (0.85), split-half reliability (0.78), and test–retest reliability (ri = 0.99), all P < 0.0005. Responsiveness was excellent with an effect size of 1.35 and a standardized response mean of 1.04. The mean ± SD time to complete the QoR-15 was 2.4 ± 0.8min. Conclusions: The QoR-15 provides a valid, extensive, and yet efficient evaluation of postoperative QoR.

Abstract Background Several quality of recovery (QoR) health status scales have been developed to quantify the patient’s experience after anesthesia and surgery, but to date, it is unclear what constitutes the minimal clinically important difference (MCID). That is, what minimal change in score would indicate a meaningful change in a patient’s health status? Methods The authors enrolled a sequential, unselected cohort of patients recovering from surgery and used three QoR scales (the 9-item QoR score, the 15-item QoR-15, and the 40-item QoR-40) to quantify a patient’s recovery after surgery and anesthesia. The authors compared changes in patient QoR scores with a global rating of change questionnaire using an anchor-based method and three distribution-based methods (0.3 SD, standard error of the measurement, and 5% range). The authors then averaged the change estimates to determine the MCID for each QoR scale. Results The authors enrolled 204 patients at the first postoperative visit, and 199 were available for a second interview; a further 24 patients were available at the third interview. The QoR scores improved significantly between the first two interviews. Triangulation of distribution- and anchor-based methods results in an MCID of 0.92, 8.0, and 6.3 for the QoR score, QoR-15, and QoR-40, respectively. Conclusion Perioperative interventions that result in a change of 0.9 for the QoR score, 8.0 for the QoR-15, or 6.3 for the QoR-40 signify a clinically important improvement or deterioration.

No studies are currently evaluating the quality of recovery (QoR) after open radical nephrectomy (ORN) and epidural morphine analgesia. This was a randomized, prospective, and controlled study that explored the QoR on the first postoperative day after ORN. Eighty subjects were randomized into two groups. The first group received general anesthesia combined with epidural anesthesia and postoperative epidural analgesia with morphine and ropivacaine. The second group received general anesthesia and continuous postoperative intravenous analgesia with tramadol. Both groups received multimodal analgesia with metamizole. The primary outcome measure was the total QoR-40 score. The secondary outcome measures were QoR-15, QoR-VAS, and the visual analog scale (VAS) for pain, anxiety, and nausea. The median difference in the QoR-40 score after 24 postoperative hours between the two groups of patients was 10 (95% CI: 15 to 5), p < 0.0001. The median score and IQR of QoR-40 during the first 24 postoperative hours in the epidural group was 180 (9.5), and in the control group, it was 170 (13). The general independence test for secondary outcomes between groups was significant (p < 0.01). QoR-VAS was correlated with QoR-40 (r = 0.63, p ≤ 0.001) and with QoR-15 (r = 0.54, p ≤ 0.001). The total QoR-40 and QoR-15 alpha coefficients with a 95% CI were 0.88 (0.85–0.92) and 0.73 (0.64–0.81), respectively. There was a significant difference in the QoR between the epidural and the control groups after ORN. The QoR-40 and QoR-15 showed good convergent validity and reliability.

Quality of recovery after anesthesia is an important measure of the early postoperative health status of patients. The Quality of Recovery-15 (QoR-15) questionnaire is a self-rated questionnaire used to assess the quality of postoperative recovery. This study is aimed at translating and validating the Korean version of QoR-15 (QoR-15K). One hundred fifty patients were included in this study. We translated the original version of QoR-15 into QoR-15K and evaluated its validity, reliability, responsiveness, and clinical feasibility. QoR-15K showed acceptable criterion, structure, and construct validities. Reliability was verified using Cronbach’s α (0.856), standard error of measurement (10.78), split-half reliability (0.831), test-retest reliability ( ρ = 0.945 , P ≤ 0.001 ), and intraclass correlation test-retest ( ρ = 0.903 , P ≤ 0.001 ). These results represent an acceptable reliability. Responsiveness was verified using Cohen’s effect size (1.39), standardized response mean (1.03), and the correlation between QoR-15K score and duration of anesthesia ( ρ = − 0.197 , P = 0.016 ). These results show acceptable responsiveness. The mean ± standard deviation time to complete QoR-15K was 138.1 ± 30.7 s . QoR-15K was rated more than adequate on the COnsensus-based Standards for the selection of health Measurement INstruments checklist. In conclusion, QoR-15K shows acceptable validity, reliability, responsiveness, and clinical feasibility and may help evaluate postoperative quality of recovery in Korean populations.

Introduction Patients’ perception of postoperative recovery is a key aspect of perioperative care. Self-reported quality of recovery (QoR) has evolved as a relevant endpoint in perioperative research. Several psychometric instruments have been introduced to assess self-reported recovery 24 hours after surgery. However, there is no questionnaire suitable for use in the postanesthesia care unit (PACU). We aimed to develop and psychometrically evaluate a QoR questionnaire for the PACU (QoR-PACU). Methods The QoR-PACU was developed in German language based on the 40-item QoR-40 questionnaire. Between March and November 2020, adult patients scheduled for elective urologic surgery completed the QoR-PACU preoperatively and during the PACU stay. We evaluated feasibility, validity, reliability, and responsiveness. Results We included 375 patients. After two piloting phases including 72 and 48 patients, respectively, we administered the final version of the QoR-PACU to 255 patients, with a completion rate of 96.5%. Patients completed the QoR-PACU at a median of 125.0 (83.0; 156.8) min after arrival in the PACU. Construct validity was good with postoperative QoR-PACU sum scores correlating with age (r = 0.23, 95% CI: 0.11 to 0.35, p < 0.001), length of PACU stay (r = -0.15, 95%CI: -0.27 to -0.03, p = 0.02), pain in the PACU (r = -0.48, 95% CI: -0.57 to -0.37, p < 0.001) and piritramide dose administered (r = -0.29, 95% CI: -0.40 to -0.17, p < 0.001). Cronbach’s alpha was 0.67 (95% CI: 0.61–0.73) with moderate test-retest reliability (ICC of 0.67, 95% CI: 0.38 to 0.83). Cohen’s effect size was 3.08 and the standardized response mean was 1.65 indicating adequate responsiveness. Conclusion The assessment of QoR in the early postoperative period is feasible. We found high acceptability, good validity, adequate responsiveness, and moderate reliability. Future studies should evaluate the psychometric properties of the QoR-PACU in more heterogeneous patient populations including female and gender-diverse patients with varying degress of perioperative risk.

ABSTRACT Background: Patient-centered outcome measures should be evaluated postoperatively as the recovery after surgery varies between patients. We aimed to evaluate the feasibility, reliability, and trajectory of the quality of recovery-15 (QoR-15) in patients undergoing cardiothoracic and aortic surgeries. Materials and Methods: This retrospective study included adult patients who underwent elective cardiothoracic and aortic surgeries. The primary outcome was the QoR-15, with a minimal clinically important difference of 6.8, assessed on postoperative days (POD) 2, 4, and 7. The final analysis included patients with at least one valid outcome. Feasibility and reliability were assessed by the successful completion rate on each POD and using Cronbach’s alpha of the QoR-15 on POD 4. A linear mixed model was used to evaluate the trajectory of the postoperative QoR-15 scores. Results: Of the 36 eligible patients, 30 with a mean age of 70 years were included in the final analysis. The successful completion rates on POD 2, 4, and 7 were 72.7%, 87.8%, and 87.8%, respectively. The mean QoR-15 scores on POD 2, 4, and 7 were 89.9, 98.0, and 108.3, respectively. The QoR-15 scores on POD 2 and 4 were not statistically different (P = 0.06) but were clinically significant. The QoR-15 score on POD 7 was statically (P < 0.001) and clinically higher than the QoR-15 score on POD 2. Cronbach’s alpha for the QoR-15 score measured on POD 4 was 0.85. Conclusion: The QoR-15 is a feasible and valid measurement after elective cardiothoracic surgery, which increases significantly over time after surgery.

Background Factors influencing quality of recovery in cranial and spinal neurosurgical patients are not known, possibly because of lack of a suitable instrument. Therefore, the authors measured quality of recovery using the QoR-40 score (a 40-item questionnaire on quality of recovery from anesthesia). Methods With informed consent, 200 patients undergoing elective neurosurgery were recruited. The QoR-40 score, visual analog scores for pain and quality of recovery, and data on complications were collected over 90 days. The psychometrics of the QoR-40 were tested and regression models were developed to determine predictors of quality of recovery and postoperative pain. Results The QoR-40 score demonstrated significant responsiveness, validity, and reliability. In cranial surgery patients, QoR-40 scores were lower on days 1 and 2 than either preoperatively or on days 3, 30, and 90. In spinal surgery patients, QoR-40 scores were lower preoperatively and on days 1 and 2 than on days 3, 30, and 90. Longer duration of surgery, more complications, and higher visual analog scores for pain were predictors of poor quality of recovery on day 3. Cranial surgery patients had moderately severe pain on days 1 and 2, whereas spinal surgery patients reported moderate pain for the whole study period. Neurologic deficits were negatively correlated with QoR-40 scores in cranial and spinal surgery patients. Conclusions The QoR-40 score is a useful instrument with which to assess quality of recovery in cranial and spinal surgery patients. Postoperative pain and neurologic deficits correlate with poor quality of recovery in these patients.

Abstract Background We used a ten-item postoperative quality of recovery score (QoR-10) to assess the perioperative quality of care in an in-hospital ambulatory surgical unit. Methods In Phase 1 of this secular trend study (n=300 patients, 3-months duration), we collected QoR-10 scores and potential confounders, including type of anesthesia and surgery; co-morbidities; and anesthesia components of the Amsterdam scale-measured anxiety scores. Phase 2 was the one-month performance feedback learning phase in which modifiable variables identified in Phase 1 were translated to actionable steps, reinforcing the already existing routine of our department’s clinical practices, including pain, shivering and anxiety. The anesthesiology team was instructed and reminded of these steps using performance feedback methods. In Phase 3 (n=300 patients, 3-month duration) we evaluated the efficacy of this performance feedback instruction. QoR-10 scores were compared between Phase 1 and Phase 3. Results Phase 1 identified three modifiable variables as targets for improvement: postoperative shivering; percentage of patients with numerical rating pain scale (NRS)<4; and preoperative anxiety from anesthesia scores. Compared to Phase 1, significantly fewer Phase 3 patients had severe shivering (2.3% vs. 7.3%, p = 0.023), and a greater percentage had NRS < 4 points (79% vs. 49.7%, p <0.001). The percentage of patients with a high anxiety score did not differ between phases. A direct association between anxiety score and QoR-10 score was not detected. The QoR-10 score (median (IQR)) was significantly higher in Phase 3 than Phase 1: 50 (49–50) vs. 49(49–50), p<0.001. In a multivariable logistic regression analysis, odds for a QoR-10 score of 49–50 were 1.92 higher in Phase 3 than Phase 1. Conclusion Considering the study limitations, team feedback education contributed to improvement of the QoR-10 score, reduced the proportion of patients with severe shivering and increased the percentage of patients with low pain scores.

In recent years, there has been a significant increase in the demand for streaming of high quality videos on the smart mobile phones. In order to meet the user quality requirements, it is important to maintain the end user quality while taking the resource consumption into consideration. This demand caught the attention of the research communities and network providers to prioritize Quality of Experience (QoE) in addition to the Quality of Service (QoS). In order to meet the users’ expectations, the QoE studies have gained utmost importance, thus creating the challenge of evaluating it in such a way that the quality, cost and energy consumption are taken into account. This gave way to the concept of QoE-aware sustainable throughput, which denotes the maximal throughput at which QoE problems can be still kept at a desired level. The aim of the thesis is to determine the sustainable throughput values from the QoE perspective. The values are observed for different delay and packet loss values in wireless and mobile scenarios. The evaluation is done using the subjective video quality assessment method. In the subjective assessment method, the evaluation is done using the ITU-T recommended Absolute Category Rating (ACR). The video quality ratings are taken from the users, and are then averaged to obtain the Mean Opinion Score (MOS). The obtained scores are used for analysis in determining the sustainable throughput values from the users’ perspective. From the results it is determined that, for all the video test cases, the videos are rated better quality at low packet loss values and low delay values. The quality of the videos with the presence of delay is rated high compared to the video quality in the case of packet loss. It was observed that the high resolution videos are feeble in the presence of higher disturbances i.e. high packet loss and larger delays. From considering all the cases, it can be observed that the QoE disturbances due to the delivery issues is at an acceptable minimum for the 360px video. Hence, the 480x360 video is the threshold to sustain the video quality.

Full textAbstract:
The web user usually expects a better Quality of Service (QoS) from the Internet Service Provider (ISP) for the best Quality of Experience (QoE). User satisfaction and feedback is one of the most important factors for the service providers to determine their QoS and improve the network performance. Service providers are more interested in QoE to provide a better service to their users to maintain their customers in the competitive market. Since there is no much study work conducted in the QoE on web browsing, only a few studies are available for getting user feedbacks. So the ISP is facing a difficulty in the assessment of the user experience in the real time network. Network level performance can be measured by the ISP for QoS and user feedback can be measured for QoE. There is no study available on relating both the QoS and QoE. Relating the network level performance and the user perception is a difficult task for the service providers. In this study we have correlated both the network level traffic performance and user experience. In our experiment the user QoE is tested by applying various off times applied to some specific packets. Our main aim is to evaluate the network level performance and correlate it with the user feedback. Later, on focusing the network level performance network traffic is analyzed for different sessions with off times applied in DNS response, Base file response and Object response. We have discussed in the results by correlating the different sessions of off times that we applied and user feedback MOS. We have also discussed the relation of the network off time in the network with the number of requests sent from client to server and the number of flag bits like SYN & ACK, FIN & ACK and RST flags between the client and server. In this study we also discussed about the user feedback and how the user suffers on varying long response time. Finally, we conclude from our results about the major factor that affects the user feedback and the user interest in using the service again.<br>chakri PH: +918008316269

Mobile data traffic will continue to show rapid growth in the coming years; however the data revenue is not rising fast enough to ensure the operators’ profitability. Therefore, mobile operators must seek new approaches to find out what service does the customers need and what quality makes the customers satisfied in order to keep their increasingly sophisticated customers satisfied at the same time minimizing their revenue gap. This paper investigate the effect of mobile cellular network performance and contextual factors on smartphone users’ satisfaction, this was done via crowdsourcing through an experiment where an Android Application and a user Survey were included, which is able to evaluate and analyze the perceived quality of experience (QoE) for YouTube service for Android Smartphone users. To achieve this goal, the App NPT performs measurements of objective quality of service (QoS) parameters, whereas the survey carriers out collecting subjective user opinion. The result show that network performance parameters do impact the MOS (Mean Opinion Score) exponentially, either in a positively or negatively way, however, multiple parameters need to be considered together in order to draw a more accurate correlation with QoE. In addition, QoE are heavily affected by many other contextual factors, such as age and gender as well as users location. QoE are also impacted by several subjective factors, such as user expectation. Not always the highest throughput will lead to the best QoE, and not always the best technology (LTE) deserves the best MOS. Even though user received very high downlink throughput, their MOS value may still be low due to they might think the video were not fun to watch and the quality has not meet their expectation.

Avec l'hétérogénéité des réseaux et la demande croissante de services multimédias, la Qualité d'Expérience (QoE) devient un facteur déterminant de réussite ou d’échec de ces services. Dans cette thèse, nous avons d’abord analysé l'impact des paramètres de qualité sur l'engagement de l'utilisateur, afin de comprendre l’effet des paramètres vidéo (temps de démarrage, qualité intrinsèque, taux de blocage) et la popularité du service sur l'engagement de l'utilisateur. Nos résultats ont montré que le taux de blocage et la popularité du service sont des paramètres critiques qui impactent fortement la satisfaction et l'engagement de l’utilisateur, tandis que, le temps de démarrage a moins d’impact. Ensuite, les approches subjectives de QoE comme le Mean Opinion Score (MOS) ont été traité dans cette thèse, où les utilisateurs sont appelés à donner une note de satisfaction en fonction des informations de contextes. Une analyse statistique des résultats obtenus à partir de tests utilisateurs a montré que le type de terminal et de contenu sont des paramètres qui impactent fortement le MOS. En plus, des modèles mathématiques d’estimation de QoE en fonction des informations de contextes ont été proposés. Enfin, deux techniques d’optimisations ont été proposées : Le MDASH (MOS Dynamic Adaptive Streaming over HTTP) pour l’optimisation vidéo de flux partageant les mêmes ressources, de manière à garantir une certaine QoE pour tous les utilisateurs. Et une optimisation de livraison, basée sur des fonctions d’utilités dans laquelle, une fonction globale d'utilité est calculée en fonction de différentes contraintes (qui dépendent fortement des stratégies des acteurs de la chaîne de livraison)<br>With the network heterogeneity and increasing demand of multimedia services, Quality of Experience (QoE) becomes a crucial determinant of the success or failure of these services. In this thesis, we first propose to analyze the impact of quality metrics on user engagement, in order to understand the effects of video metrics (video startup time, average bitrate, buffering ratio) and content popularity on user engagement. Our results show that video buffering and content popularity are critical parameters which strongly impacts the end-user’s satisfaction and user engagement, while the video startup time appears as less significant. On other hand, we consider subjective approaches such as the Mean Opinion Score (MOS) for evaluating QoE, in which users are required to give their assessment according to contextual information. A detailed statistical analysis of our study shows the existence of non-trivial parameters impacting MOS (the type of device and the content type). We propose mathematical models to develop functional relationships between the QoE and the context information which in turn permits us to estimate the QoE. A video content optimization technique called MDASH (for MOS Dynamic Adaptive Streaming over HTTP) is proposed, which improves the perceived QoE for different video sessions sharing the same local network, while taking QoE fairness among users as a leitmotiv. We also propose a utility-based approach for video delivery optimization, in which a global utility function is computed based on different constraints (e.g. target strategies coming from the actors of the delivery chain)

To be successful in today's competitive market, service providers should look at user's satisfaction as a critical key. In order to gain a better understanding of customers' expectations, a proper evaluations which considers intrinsic characteristics of perceived quality of service is needed. Due to the subjective nature of quality, the vagueness of human judgment and the uncertainty about the degree of users' linguistic satisfaction, fuzziness is associated with quality of experience. Considering the capability of Fuzzy logic in dealing with imprecision and qualitative knowledge, it would be wise to apply it as a powerful mathematical tool for analyzing the quality of experience (QoE). This thesis proposes a fuzzy procedure to evaluate the quality of experience. In our proposed methodology, we provide a fuzzy relationship between QoE and Quality of Service (QoS) parameters. To identify this fuzzy relationship a new term called Fuzzi ed Opinion Score (FOS) representing a fuzzy quality scale is introduced. A fuzzy data mining method is applied to construct the required number of fuzzy sets. Then, the appropriate membership functions describing fuzzy sets are modeled and compared with each other. The proposed methodology will assist service providers for better decision-making and resource management.

Avec l'hétérogénéité des réseaux et la demande croissante de services multimédias, la Qualité d'Expérience (QoE) devient un facteur déterminant de réussite ou d’échec de ces services. Dans cette thèse, nous avons d’abord analysé l'impact des paramètres de qualité sur l'engagement de l'utilisateur, afin de comprendre l’effet des paramètres vidéo (temps de démarrage, qualité intrinsèque, taux de blocage) et la popularité du service sur l'engagement de l'utilisateur. Nos résultats ont montré que le taux de blocage et la popularité du service sont des paramètres critiques qui impactent fortement la satisfaction et l'engagement de l’utilisateur, tandis que, le temps de démarrage a moins d’impact. Ensuite, les approches subjectives de QoE comme le Mean Opinion Score (MOS) ont été traité dans cette thèse, où les utilisateurs sont appelés à donner une note de satisfaction en fonction des informations de contextes. Une analyse statistique des résultats obtenus à partir de tests utilisateurs a montré que le type de terminal et de contenu sont des paramètres qui impactent fortement le MOS. En plus, des modèles mathématiques d’estimation de QoE en fonction des informations de contextes ont été proposés. Enfin, deux techniques d’optimisations ont été proposées : Le MDASH (MOS Dynamic Adaptive Streaming over HTTP) pour l’optimisation vidéo de flux partageant les mêmes ressources, de manière à garantir une certaine QoE pour tous les utilisateurs. Et une optimisation de livraison, basée sur des fonctions d’utilités dans laquelle, une fonction globale d'utilité est calculée en fonction de différentes contraintes (qui dépendent fortement des stratégies des acteurs de la chaîne de livraison)<br>With the network heterogeneity and increasing demand of multimedia services, Quality of Experience (QoE) becomes a crucial determinant of the success or failure of these services. In this thesis, we first propose to analyze the impact of quality metrics on user engagement, in order to understand the effects of video metrics (video startup time, average bitrate, buffering ratio) and content popularity on user engagement. Our results show that video buffering and content popularity are critical parameters which strongly impacts the end-user’s satisfaction and user engagement, while the video startup time appears as less significant. On other hand, we consider subjective approaches such as the Mean Opinion Score (MOS) for evaluating QoE, in which users are required to give their assessment according to contextual information. A detailed statistical analysis of our study shows the existence of non-trivial parameters impacting MOS (the type of device and the content type). We propose mathematical models to develop functional relationships between the QoE and the context information which in turn permits us to estimate the QoE. A video content optimization technique called MDASH (for MOS Dynamic Adaptive Streaming over HTTP) is proposed, which improves the perceived QoE for different video sessions sharing the same local network, while taking QoE fairness among users as a leitmotiv. We also propose a utility-based approach for video delivery optimization, in which a global utility function is computed based on different constraints (e.g. target strategies coming from the actors of the delivery chain)

Full textAbstract:
The EU has been promoting unbundling of the transmission grid from other stages
of the electricity supply chain with the aim of fostering competition in the upstream stage of
electricity generation. At presence, ownership unbundling is the predominant form of
unbundling in Europe. However, the benefits of increased competition from ownership
unbundling of the transmission grid may come at the cost of lost vertical synergies between the
formerly integrated stages of electricity supply. The policy debate generally neglects such
potential costs of unbundling, yet concentrates on its benefits. Therefore European crosscountry
evidence may shed some light on this issue. This study helps fill this void by
empirically estimating the magnitude of economies of vertical integration (EVI) between
electricity generation and transmission based on a quadratic cost function. For this purpose
we employ novel firm-level panel data of major European electricity utilities. Our results
confirm the presence of substantial EVI, which put the policy measure of transmission
ownership unbundling into question. (authors' abstract)<br>Series: Working Papers / Research Institute for Regulatory Economics

But user will get unpredicted loss by decoded fake QR Code at unknowing situation. Besides, the priority of decoding QR Code fail will upgrade because of some special features or the situation that same color module gather together appear on the QR Code. This topic that decoder how to get correct message quickly and correctly, and user how to known the message is correct in QR Code needs to be discussed. To discuss how to hiding secret message in QR Code, this paper proposes two methods by QR Code scoring mechanism as the starting scoring. Firstly, hide secret message in codeword symbol with high penalty scoring module. This method has high hiding capacity, and can reduce the penalty scoring of QR Code probably. Secondly, hide message base on the target that reducing the penalty scoring warranty. This method flips the codeword symbol carefully with high penalty scoring module which propose is deciding the total penalty scoring of QR
Code will go up or not. The QR Code with the embedded secret message by two method in this paper can decode original information if the decoder is general. Decode original information but also decode secret message by the decoder that proposed in this paper. Experiment results show the proposed methods are feasible.

Full textAbstract:
Mapping between many different applications and many different underlying technologies
is very complicated. Moreover, since users need service continuity and want to get the
service in a satisfactory level, firstly, their perception of the service should be measured and secondly, the changes in the underlying technologies should be transparent to users.
As a result, there should be ”virtualization layer” between application layer and underlying access technologies whose job is to abstract user perception of the application in terms of network parameters and transfer these requirements to underlying layers. In this thesis, we propose a generic mathematical expression to abstract user perception of application in a unified way for different applications. Since today applications are composite
applications, having a generalized expression that has the same form for various
applications can ease resource management calculations. We use application service map
which is based on quality of experience for resource management.

AbstractSexual activity is an important facet of social functioning and quality of life (QoL) reflected in its inclusion in the World Health Organization’s generic, 26-item, quality of life instrument, the WHOQOL-BREF, in the item “how satisfied are you with your sex life?” Several instruments designed to assess sexual activity, function or QoL have been developed, varying in their scope, measurement properties, and applicability to certain populations. Evidence from literature reviews of instruments was synthesized to (a) identify generic self-administered instruments, which have been developed for research or clinical practice in adults and (b) to investigate their scope, psychometric properties, and applicability. We then considered these methods together with emerging Quality of Life Technologies. In total, 110 instruments were identified via nine reviews and 31 generic instruments were retained. There was a good evidence of the instruments’ internal consistency and reliability, but limited evidence of their responsiveness to change. While 31 instruments provide an adequate assessment of function/sexual QoL, fitting with COSMIN guidance, their scope varied and only three of these were developed since the revision of the definition of sexual dysfunction in 2013. Computerized self-reported measures may facilitate data collection yet were rarely discussed by authors. This meta-review has compiled evidence on generic instruments that can improve the collection of data on sexual function/QoL in research and clinical practice. We also discuss the emerging use of applications, connected wearables and devices that may provide another less invasive avenue for the assessment of sexual function/QoL at the individual and population level.

Full textAbstract:
This paper investigates quantifiers and their scope in Persian, proposing that Persian is not a scope-rigid language, rather scope rigidity in this language is a construction-specific property controlled by scrambling. In other words, the availability of scrambling translates into lack of ambiguity (for similar arguments, see Hoji 1985, 1986 for Japanese; Ionin 2001 for Russian; Bobaljik & Wurmbrand 2012 for German). I further propose that in Persian, the nature and the size of scrambling is what dictates the presence or absence of scope ambiguity, whereby the vP-internal scrambling cases induce ambiguity while the vP-external ones do not. Examples from various sentences with two quantifiers show that although Persian exhibits a strong preference for surface scope in general, constructions involving inverse linking, for which only the inverse scope is possible, justify that a Quantifier Raising (QR) operation is available in this language, contradicting Karimi (2005). This paper draws on Bobaljik & Wurmbrand’s (2012) (B&W) constraint-based proposal and the negative correlation between scrambling and scope ambiguity.

Full textAbstract:
AbstractThe diagnosis of Graves’ orbitopathy is based on a typical clinical presentation, supported by a family history of Graves’ disease, in combination with typical findings on CT or MRI scans and/or elevated serum levels of TSH-receptor-binding immunoglobulins and anti-thyroid peroxidase. In order to treat patients with Graves’ orbitopathy, not only the diagnosis, but also the severity and activity scores have to be assessed. The impact of a diagnosis of Graves’ orbitopathy should not be underestimated. The disease-specific quality-of-life questionnaire for patients with Graves’ orbitopathy, the so-called GO-QOL, is very helpful to perceive the disease from the patient’s point of view.

Full textAbstract:
Scoliosis significantly impacts Quality of Life (QOL). Current quality of life questionnaires for adolescents with idiopathic scoliosis (AIS) have limitations. A new questionnaire for measuring QOL in AIS called the Italian Spine Youth Quality of Life (ISYQOL) has been developed to address these limitations but the English translation has not yet been validated. To determine the ceiling and floor effects, and the convergent validity of the ISYQOL questionnaire against established QOL questionnaires and Cobb angle in AIS. One hundred consecutive females with AIS, (10–18 years old), treated non-operatively. The English translation of the ISYQOL was compared to the following established questionnaires: Scoliosis Research Society-22r and the Spinal Appearance Questionnaire. The participants were 100 females (13.89+/-1.8 years) with 28.75+/-13.9° curve angles. The convergent validity of the ISYQOL score (60.3+/-12.44) was supported by significant correlation with the SRS-22r total score, function, pain, self-image, and mental health scores (r = 0.70, 0.54, 0.57, 0.52 and 0.50, respectively), and with the SAQ general, waist, and expectations domains (r = -0.6. -.52, and -0.56, respectively). Correlation with the Cobb angle was (r = -.37)(see Table 1). No ceiling effect was observed in the ISYQOL. Ceiling effects were observed for the SRS-22r and the SAQ. The ISYQOL demonstrated evidence of convergent validity. This study supports its suitability for QOL research in AIS. ISYQOL appears more likely to detect changes in evaluative studies than the SRS- 22r and the SAQ.

This work aims to enhance dependent persons’ quality of life (QOL) by examining various aspects of their lives and providing the required assistance to enhance each aspect of their QOL. We employ machine learning methods to evaluate the eight aspects of QOL and forecast the corresponding index value. Machine learning algorithms input eight aspects of QOL and predict the QOL index value. The QOL Index value says the requirement of the support to a person, and it depends on eight aspects of the QOL. We use our dataset to train the machine learning model. Dataset is collected using the GENCAT scale tool, which takes 69 items and provides the score value for each aspect of the QOL. We apply many linear and nonlinear machine learning regression algorithms. The multiple linear regression algorithm results show better performance for root mean squared error (1.4729) and R2 score (0.9918).

Full textAbstract:
Information on patient quality of life (QOL) is essential to many clinical decisions. Therefore, studies that aim to extract QOL information from patient narratives are increasingly drawing attention. Also, several studies have noted that web services for patients, such as patient social networking services, may represent promising resources for QOL research. However, it is still unclear whether patient narrative text contains corresponding amounts of QOL information as self-reported QOL. This study investigates if medical staff can accurately estimate patient QOL from only patient narrative texts. We analyzed (1) QOL of cancer patients estimated by medical staff from patient autobiographical texts and (2) self-reported QOL scores of cancer patients. We compared patients from the following 3 disease groups: (1) gastrointestinal cancer, (2) breast cancer, and (3) lymphoma. The SF-36v2&trade; Health Survey was used to measure patient QOL in both materials, and the QOLs were compared. We found significant differences between self-reported QOL and estimated QOL in breast cancer patients and lymphoma patients, but not in gastrointestinal cancer patients. In particular, the medical staff tended to underestimate physical QOL scores. Medical staff may underestimate several aspects of QOL scores. On the basis of these results, we may be able to achieve more precise QOL estimation from patient narratives.

This cross-sectional aimed to; 1) to explore the symptom management and quality of life (QoL) of palliative cancer patients, 2) to compare the perceived QoL outcomes between the patient who received standard treatment (ST) and who were treated with Cannabis treatment (CT). The study was carried out between 1st Febuary to 30st September 2021 from two hospitals in Roi-Et Regional Hospital and Sawang Dandin Crown Prince Hospital in Thailand. Using the EORTCQLQ-C30 and PPS assessment form, analysing with descriptive statistics, comparing mean scores for two patient groups by Independent T-test. The results found that patients of CT groups had a very high level of QoL while ST group had a high level. The consistency was statistically significant for overall QoL scores of CT higher than ST group (P-value < 001.0) both Cognitive functioning and Dyspnea symptoms (p-value=.05). However, the insomnia symptom indicated ST scores was higher than CT (P-value < 001.0). The results confirm that established the efficacy and safety of medical use of cannabis was benefit for patients. Therefore, it will be enhancing healthcare professionals to take opportunities for treatment for palliative patients’ care.

АBSTRACT Introduction: The Physiotherapy (PT) is an important part of cancer treatment and could be recovery PT, maintenance PT and palliative PT. The aim of the study is to investigate the impact of early postoperative PT on the functional and mental recovery of a 57-year-old patient with colon cancer. Research methods: On the second and seventh postoperative day, we applied a Quality of Recovery-40 (QoR-15) questionnaire, Cumulated Ambulation Score (CAS) and Hospital Anxiety and Depression Scale (HADS) and а 6 min walk-test – on the third and seventh postoperative day. The special PT is used to improve the respiratory function, to alleviate the unpleasant sensations of the gastrointestinal tract, to reduce pain, to restore mobility through training in painless sitting, standing up, and walking, as well as to reduce anxiety and to overcome depressive symptoms. Results: Applied PT in the early postoperative period in severe abdominal surgery for colon cancer prevented postoperative complications. The results show a significant improvement in the studied indicators and good quality of recovery; patient’s independence in standing up, sitting, and walking; pain relief; reduced anxiety and depressive moods. Conclusion: The application of early PT is an important part of patient’s post-surgical care. It helps for optimal recovery and prepares him for the next additional therapies such as chemotherapy, radiation therapy, etc.

Cloud gaming (CG) traffic requires high bandwidth and low latency to ensure Quality of Experience (QoE). We propose DCTPQ, an ML-based edge solution that dynamically identifies and prioritizes CG traffic on-the-fly, achieving 97.6% classification accuracy using packet-based and RTP frame-based features with Decision Tree (DT) and Random Forest (RF) models. DCTPQ employs separate queues for CG, UDP (Non-CG), and TCP traffic, with varied lengths and rates, implemented using P4 on the data plane. Leveraging Inband Network Telemetry (INT) and Device-in-the-Loop (DIL) techniques, we evaluate QoS (throughput, latency, packet sojourn time) and QoE (VMAF score) under congestion. The system is tested with three distinct CG games (Fortnite, Forza, Mortal Kombat) on the Xbox platform, while users play online, ensuring a realistic assessment of the deployed model’s impact on QoS and QoE.

Background: DBS is an established treatment option in refractory dystonia, and motor outcomes have been extensively evaluated instead of the usually neglected NMS (e.g., pain). Objective: To describe the non-motor symptoms (NMS) after Deep Brain Stimulation (DBS) surgery for refractory generalized inherited/idiopathic dystonia in a prospective study. Design and setting: A prospective study that evaluated patients in the Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo. Methods: This study evaluated patients before and one year after DBS surgery. We applied the following scales: Burke-Fahn-Marsden Rating Scale (BFMRS), Hospital Anxiety and Depression Scale (HADS), Non-Motor Symptoms Scale for Parkinson’s Disease (NMSS-PD), Parkinson’s Disease Questionnaire-8 (PDQ8) Brief Pain Inventory (BPI), Neuropathic Pain Symptom Inventory (NPSI) and McGill pain questionnaire. Results: 11 patients (38.35 ± 11.30 years) underwent surgery (36.3% women). Motor BFMRS subscore was 64.36 ± 22.94 at baseline and 33.55 ± 17.44 after surgery (p=0.003, 47.9% improvement on motor symptoms). HADS scores remained unchanged. NMSS-PD had a significant change after DBS, from 70.91 ± 59.07 to 37.18 ± 55.05 (p=0.013, 47,5% improvement). Seven patients reported pain before DBS surgery, and after one year, four patients reported chronic pain (i.e., pain improved by 42.28%). BPI’s severity and interference scores were 4.61 ± 2.84 and 4.12 ± 2.67, respectively before surgery, and 2.79 ± 2.31 (0.00–6.25) and 1.12 ± 1.32 (0.00–3.00) after DBS (p=0.043 and p=0.028). NPSI total score was 15.29 ± 13.94 before DBS, and reduced to 2.29 ± 2.98 afterward (p=0.028). McGill’s total score was 9.00 ± 3.32 before DBS, achieving 2.71 ± 2.93 after surgery (p=0.028), mostly driven by the sensory sub-score. Conclusions: We found that DBS improves NMS in dystonia, including chronic pain, anxiety, gastrointestinal symptoms, besides the already established improvement in QoL and motor symptoms.

Objective: Breast-conserving surgery (BCS), compared with mastectomy, guarantees equivalent local control and survival, with lower morbidity and higher quality of life (QOL). However, the cosmetic result (CR) of this surgery can be unsatisfactory and influence the survivor’s QOL. This issue exacerbates when the patient reports dissatisfaction despite good results determined by healthcare professionals and/or objective methods. Thus, it is necessary to understand the impact of CR on QOL, as well as potential influencing factors. Methodology: A cross-sectional, prospective study (ethical approval and FAPESP) was conducted, including patients undergoing BCS. Patients completed the EORTC-C30, QLQ-BR23, and BCTOS questionnaires, performed self-assessment of breast cosmetics, and had photographs taken. The photographs were analyzed using BCCT.core software. For categorical variables, frequencies were calculated, and for numerical variables, mean and standard deviation were determined. The results of BCCT.core were compared with patient self-assessment, analyzing four groups: satisfied, very satisfied, true-dissatisfied, and false-dissatisfied. Kappa was used to assess agreement between categorical variables, and Student t and Mann-Whitney tests were employed to evaluate the relationship between QOL and CR. ANOVA and Bonferroni adjustment was used to compare groups. Results: A total of 300 patients were evaluated, 298 completed self-assessment of their breasts (76.8% satisfactory result and 23.2% unsatisfactory) and 297 had BCCT.core evaluation (29.9% satisfactory result and 79.1% unsatisfactory), with a kappa of 0.095 (p=0.01). In self- -assessment, patients with unsatisfactory CR showed worse QOL scores in 17 items. Under software analysis, this relationship did not have the same proportion, with unsatisfied patients showing worse scores in only four items. In falsely dissatisfied patients (satisfactory result by software and unsatisfactory self-assessment), higher scores of pain and worse functionality were found on the treated side. Conclusion: Unsatisfactory CRs were associated with worse QOL scores, a fact that may be linked to other aspects such as breast pain and functionality.

INTRODUCTION The TB-PRACTECAL study trialed a shorter, more tolerable regimen of oral drugs than standard of care (SoC) – which can last for up to 20 months and involve both injectables and up to 20 tablets a day. In this sub-study, PRACTECAL-PRO, we measured and explored trial participant quality of life, experiences, and perspectives on treatment, to understand outcomes more fully. Both studies were conducted in Uzbekistan, South Africa, and Belarus. METHODS We conducted a mixed-methods evaluation using quality of life (QoL) surveys and in-depth interviews. Participants in investigational and SoC arms completed the Short Form 12 (SF-12) and St George’s Respiratory Questionnaire (SGRQ) at four timepoints (baseline, 12, 24, and 48 weeks). Healthy age- and sex-matched volunteers were surveyed at a single timepoint to establish locally relevant controls. Participants from investigational arms were purposively sampled for in-depth interviews to describe qualitatively patient satisfaction and experience with the investigational arm trial, including factors enabling toleration or rejection of a novel treatment by patients. ETHICS This study was approved by the MSF Ethics Review Board and by the ethics review committees of the Ministry of Health of the Republic of Uzbekistan; the Republican Scientific and Practical Centre for Pulmonology and Tuberculosis, Belarus; the regulatory authority of the Ministry of Health of the Republic of Belarus and Pharma Ethics Independent Ethics Committee, South Africa. RESULTS Overall, of 137 trial participants 28.5% (39) and 71.5% (98) were randomised to the SoC arm and one of three investigational arms, respectively. Statistically significant univariate scores by arm were observed at week 48 for SGRQ Impact domain (median -3.8, 95% confidence interval (CI), -5.7 to 0.0) and at week 24 for SF-12 physical component score (median 3.1, 95%CI 0.2 to 6.7). Longitudinal analysis showed that the proportional reduction in SGRQ scores per month was higher in the investigational group compared to the SoC for all domains and the total score. For both the SGRQ and SF-12, baseline scores indicated worse quality of life for the trial participant group (that is, investigational arms and SoC together) than for the healthy control group. Qualitative analysis showed early treatment satisfaction was a useful predictor of better adherence. Treatment acceptability was linked to participants’ support networks and their experience of counselling and clinical advice. Tolerability of the regimen helped reassure patients and household members on efficacy and value of the treatment. Participants reported that early improvement helped them return to productive lives sooner, with the potential to address social determinants with financial protection schemes for a shorter investment period. Patient perspectives around residual burden of disease can help inform clinicians about ongoing care. CONCLUSION All PRACTECAL-PRO participants reported worse generic and disease-specific QoL at baseline, compared to an age and sex-matched healthy control group. Participants taking a novel shortened oral regimens demonstrated both a quicker improvement in their respiratory disease-specific QoL over 48 weeks than those receiving SoC, and an improvement that exceeded the SGRQ’s minimum clinically important difference. In-depth interviews give insights suggesting investment toward patient-sensitive and socially responsive treatment and care. For interviewees, the supportive care experienced was as important as their satisfaction and tolerability of the novel drug regimen. Patient perspectives are an essential component of assessing clinical trial outcomes. CONFLCITS OF INTEREST None declared.

Objective: This study aimed to assess the quality of life (QoL) of breast cancer patients after surgical treatment, compare groups undergoing conservative, radical, and oncoplastic surgeries, and identify symptoms and treatment-related factors that worsen QoL. Methodology: This is an observational, cross-sectional, descriptive, and single-institution study that evaluated QoL in state public servants with breast cancer undergoing surgical treatment at the Hospital do Servidor Público Estadual de São Paulo (HSPE) from October 2021 to December 2022. The study included patients with in situ or non-metastatic invasive breast cancer who completed the assessment questionnaire. The European Organization for Research and Treatment of Cancer 30-Item Quality of Life Questionnaire instruments were used for QoL assessment. The study was submitted through Plataforma Brasil to the Research Ethics Committee of the Hospital do Servidor Público Estadual de São Paulo – Francisco Morato de Oliveira and filed on Platform Brasil with approval numbers (CAAE 68337823.4.0000.5463). All patients included in the study signed the TCLE. Results: A total of 300 patients with a mean age of 56.6 years were included in the study. The majority had a partner (55.69%) and completed higher education (72.15%). The most prevalent histological type was invasive breast carcinoma (79.74%), and 69.62% of tumors had a positive hormone receptor subtype. The most common surgical treatment was conservative surgery (77.21%). According to the questionnaire, the population’s global QoL level (70.6) was satisfactory and the most affected function was emotional (65.1). The majority were satisfied with their appearance after treatment (74.9), but sexual satisfaction was impaired (57.4). Conclusion: Patients surviving BC evaluated in this study showed significant changes in QoL. The symptoms most reported by them were insomnia, pain, and fatigue. Advanced clinical staging and triple-negative molecular subtypes were associated with worse QoL scores. Conservative surgical treatment interfered less with QoL and oncoplastic surgery was associated with lower scores. Adjuvant radiotherapy did not impair QoL. Adjuvant chemotherapy was the systemic treatment that most interfered with the QoL of the patients evaluated.

Review question / Objective: The patients should meet the internationally recognized diagnostic criteria for myasthenia gravis and be definitely diagnosed as myasthenia gravis, excluding MG patients caused by congenital, drug and other factors, as well as patients with serious primary diseases, autoimmune diseases or mental diseases. Patients are not restricted by race, region, gender, age, background, course of disease and other factors. We will focus on trials using vitamin D as an intervention at any dose and in any regimen (eg daily/weekly/monthly intake). The control group was routinely given western medicine, including cholinesterase inhibitors, glucocorticoids, immunosuppressants, alone or in combination, or placebo. The intervention group was treated with vitamin D on the basis of western medicine treatment in the control group. The specific dosage form and dose were not limited, and the shortest course of treatment should be 4 weeks. Main outcome measures: (1) Quantitative score of myasthenia gravis (QMG); (2) Recurrence rate; (3) Effective. Secondary outcome measures: (1) The level of serum acetylcholine receptor antibody (AchRab); (2) The levels of inflammatory factors such as IL-6 and IL-10; (3) Clinical absolute score; (4) TCM syndrome score scale; (5) Quality of life score (QOL); (6) Incidence rate of adverse events. All randomized controlled trials (RCT) literatures from the establishment to September 2022 were retrieved and classified.

Review question / Objective: P (Population): patients with neurogenic bladder (NB) after spinal cord injury; I (Intervention): sacral magnetic stimulation and routine rehabilitation training; C (Comparison): routine rehabilitation training and/or sham-sacral magnetic stimulation; O (Outcome): urinary frequency, voided volume, maximum urination volume，first sensation capacity, maximum bladder volume, maximum bladder pressure, QOL (Quality of Life Score), VAS(Visual Analogue Scale), LUTS (Lower Urinary Tract Symptoms); S (Study): Randomized controlled trial, RCT. Condition being studied: Spinal cord injury (SCI) leads to long-term disabilities with significant social and economic consequences. After SCI, bladder dysfunction is common and improved bladder function consistently ranks as the top quality of life priority in individuals with SCI. Patients with a neurogenic bladder following SCI often catheterize themselves to empty the bladder, and urinary tract infections and obstructive uropathies are common.
