Enhancing Quality of Experience in Malay Language Dyslexia Screening Test

Identifying dyslexia among Malaysian citizens, especially children nowadays is a prominent issue. The usual practice of dyslexia screening tests in the Malaysian school system is by teacher's observation and intervention. However, this is usually time-consuming, less accurate and lacking additional supporting tools. Moreover, dyslexic children enrolling in a normal education system will encounter many problems for the teacher and the children themselves. A Malay language mobile-based application for a dyslexia screening test named Kiddo Disleksia has been developed to solve this issue. However, it has not been tested in terms of Quality of Experience (QoE) as well as usability. Therefore, this research aims to test the QoE level of Kiddo Disleksia and also to compare the traditional dyslexia screening test with Kiddo Disleksia in terms of usability. To test the QoE, several special education teachers are required to rate Kiddo Disleksia using Mean Opinion Score (MOS). Ten children were tested using Kiddo Disleksia and 80% of them recognized as dyslexic. This result also similar with the traditional paper-based screening test. Therefore, the Kiddo Disleksia application is considered reliable for dyslexia screening tests for children. For QoE, the results show that the mean values of MOS are 3.9 and above. Therefore, the quality of experience during dyslexia screening tests can be enhanced using Kiddo Disleksia.

The Quality of Experience (QoE) evaluation for mobile streaming service over LTE network is essential for mobile networking development. However, few QoE researches for mobile streaming service focus on LTE network. Based on the research of QoE for mobile streaming service over other networks, this paper achieves the simulation for network transmission for different videos using H.264 format on the ns-3 LTE simulation platform. What’s more, exponential model fittings are performed for not only single Quality of Service (QoS) parameter and QoE, but also multiple QoS parameters and QoE. Simulation results show that the network parameters and the Mean Opinion Score (MOS) of QoE have strong exponential relationships for streaming service over LTE network.

Quality of Experience (QoE) of video streaming services has been attracting more and more attention recently. Therefore, in this work we designed and implemented a real-time QoE monitoring system for streaming services with Adaptive Media Playout (AMP), which was implemented into the VideoLAN Client (VLC) media player to dynamically adjust the playout rate of videos according to the buffer fullness of the client buffer. The QoE monitoring system reports the QoE of streaming services in real time so that network/content providers can monitor the qualities of their services and resolve troubles immediately whenever their subscribers encounter them. Several experiments including wired and wireless streaming were conducted to show the effectiveness of the implemented AMP and QoE monitoring system. Experimental results demonstrate that AMP significantly improves the QoE of streaming services according to the Mean Opinion Score (MOS) estimated by our developed program. Additionally, some challenging issues in wireless streaming have been easily identified using the developed QoE monitoring system.

Online multiplayer games require internet networks to play with opposing players more exciting because multiple players can fight each other. The game experiences lag, which is expressed as the quality of experience (QoE), is one of the most common problems for online multiplayer games, causing the games less exciting to play. This study examined the implementation of Message Queue Telemetry Transport (MQTT) as a communication protocol in multiplayer online games using Arduino and compared its performance against HTTP. QoE used data collected using the mean opinion score (MOS) method. The MQTT resulted in an average QoE score of 3.9 (Pingpong) and 4 (TicTacToe) MOS units, while on HTTP 3.8 (PingPong and TicTacToe). The use of the MQTT communication protocol can improve the QoE of multiplayer online game players compared to HTTP.

Proper peer review and quality of published articles are often regarded as signs of reliable scientific journals. The aim of this study was to compare whether the quality of statistical reporting and data presentation differs among articles published in ‘predatory dental journals’ and in other dental journals. We evaluated 50 articles published in ‘predatory open access (OA) journals’ and 100 clinical trials published in legitimate dental journals between 2019 and 2020. The quality of statistical reporting and data presentation of each paper was assessed on a scale from 0 (poor) to 10 (high). The mean (SD) quality score of the statistical reporting and data presentation was 2.5 (1.4) for the predatory OA journals, 4.8 (1.8) for the legitimate OA journals, and 5.6 (1.8) for the more visible dental journals. The mean values differed significantly (p < 0.001). The quality of statistical reporting of clinical studies published in predatory journals was found to be lower than in open access and highly cited journals. This difference in quality is a wake-up call to consume study results critically. Poor statistical reporting indicates wider general lower quality in publications where the authors and journals are less likely to be critiqued by peer review.

Background:Boolean remission criteria is one most popular and stringent criteria in treating patient with rheumatoid arthritis (RA), because it may guarantees a stable clinical course after attaining remission.Objectives:Impact of time span from initiation to achieving Boolean remission on maintaining disease activity, daily activities, and quality of life after attaining Boolean remission was investigated from daily clinical practice data.Methods:685 patients with RA since August 2010 under the T2T strategy were treated. They were monitored for their TJC, SJC, PGA, EGA, CRP, and disease activity indices such as CDAI, SDAI, DAS28, and Boolean criteria at every visit. HAQ-DI score, pain score using visual analog scale (PS-VAS), and EQ-5D were also monitored, and the quality of life score (QOLS) calculated from EQ-5D was determined at every visit from the time of diagnosis (baseline).Of 685 patients, 465 patients had achieved Boolean remission >1 times, and were consecutively followed up for >3 years. These patients were enrolled in the study. Time span from the first visit to first Boolean remission was calculated. The relationship between the time span and each of background parameters, and the relationship between the time span and each of the mean values of the SDAI score, HAQ score, PS-VAS, SHS, and QOLS at the first Boolean remission and thereafter was evaluated statistically.Patients were subsequently divided into the G ≤ 6 and G > 6 groups based on the achievement of first Boolean remission within two groups: time span G ≤ 6 months and G > 6 months. The two groups were compared with regard to the SDAI score, HAQ score, PS-VAS, SHS, and QOLS at first visit and at the time of first Boolean remission, and the mean values of these parameters after remission were evaluated statistically. Moreover, changes of these parameters and the mean Boolean remission rate after the first remission, and SDAI remission rate at the first Boolean remission to thereafter were compared between the two groups statistically.Results:Out of 465 patients, females comprised 343 (73.7%), and the mean age was 67.8 years (range, from 21–95 years). The mean disease duration at first visit was 6.1 years (range, from 1 months–45 years). The mean follow up length was 88.1 months (range: 36–122 months; median: 85 months) and mean time span from the first visit to the first Boolean remission was 8.1 months. The mean SDAI score, HAQ score, PS-VAS, and the QOLS at first visit were 13.3, 0.467, 33.2, and 0.834, respectively. Among the study parameters, PS-VAS and QOLS were significantly correlated with the time span. For parameters at the first Boolean remission, HAQ-DI score, PS-VAS, and QOLS demonstrated significant correlation with the time span, whereas SDAI, HAQ-DI score, PS-VAS, SHS, and QOLS after the Boolean remission demonstrated significant correlation with the time span.The comparison between the G ≤ 6 and the G > 6 groups revealed that the disease duration, HAQ score, and PS-VAS at baseline in the G > 6 were significantly higher than that in the G ≤ 6 group, and QOLS in the G ≤ 6 group was significantly higher than that in the G > 6 group at baseline. Similarly, the HAQ score and PS-VAS at the first Boolean remission in the G > 6 group were significantly higher than that in the G ≤ 6 group, whereas QOLS in the G ≤ 6 group demonstrated no significant difference compared with that in the G > 6 group.The mean value of the SDAI score after the first Boolean remission in the G > 6 group was significantly higher than that in the G ≤ 6 group. Similarly, the SDAI score, HAQ score, and PS-VAS after the first Boolean remission in the G > 6 group were also significantly higher than those in the G ≤ 6 group, and the mean value of the QOLS in the G ≤ 6 group were significantly higher than that in the G > 6 group. The Boolean remission rate and SDAI remission rate after the first Boolean remission were significantly higher in the G ≤ 6 group than those in the G > 6 group.Conclusion:Attaining Boolean remission ≤ 6 months for RA has significant benefit for more stable disease control, that leads good maintenance of ADL.Disclosure of Interests:None declared

ABSTRACT: Crambe is a rapeseed with high oil content and can be used as a winter cover or as a source of raw material for the production of biodiesel, however espite the growing interest in the culture, research on the subject is still incipient, especially concerning the seed production and analysis technology. The purpose of this study is to evaluate the physiological quality of crambe seeds, 'FMS Brilhante' cultivar, by testing the pH of exudate. Five seed lots were submitted to the determination of water content and the tests of germination and vigor (first count, emergence and tetrazolium). In the conduction of pH exudate test, temperatures (25 and 30oC), and periods of seed imbibition in water (15, 30 and 45 minutes) were tested. The experiment was conducted in a completely randomized manner, with four replicates, and the mean values were compared by the Tukey test at 5% probability; Pearson correlation between the pH of the exudate and initial tests was also made. Testing the pH of exudate is promising for separating lots of crambe seeds and the following combinations of 25°C/30 minutes or 30°C/45 minutes can be used.

An investigation was undertaken to compare the relative magnitudes of the differential effects of environment (i.e., stations) and of malting methods on the malting quality of barley varieties. Samples of Olli, O.A.C. 21, Hannchen, and Regal from four stations were malted by eight methods representing the combinations of germinating at 50° and 56° F., at 42 and 46% moisture, and for six and nine days.Statistical analyses showed that, with respect to diastatic activity, wort nitrogen, and extract yield, the variations due to the differential effect of environment on varieties were greater than the variations due to the differential effect of malting methods on varieties. As a result of this study and earlier ones, it appears that the former effect is the limiting factor in studies of the comparative malting qualities of varieties. The latter effect is of less importance but must be kept in mind if errors in the interpretation of the results of routine tests are to be avoided. In general, it appears that if routine tests show that the mean values for any variety, when grown at 12 stations representing a reasonable range of environment, differ from the values for the standard variety by more than 1% in extract, or 10% in diastatic activity or wort nitrogen, a real difference exists between the varieties, which cannot be overcome by any reasonable change in malting conditions.

At the moment the suitability of stored red blood cells (sRBC) for transfusion is checked by routine methods such as haemoglobin estimation and the level of haemolysis. These methods cannot characterize directly the quality of the membranes of sRBC. The aim of this work is to assess the quality of sRBC based on such criteria as the membrane’s stiffness and the size and the form of sRBC. Materials and Methods. We have investigated 5 series of dry cytosmears of the sRBC which had been kept in blood bank in a period from 1 to 35 days. After AFM imaging, in every specimen, 5 RBC were chosen at random; the diameter, the height, and the stiffness were measured on each of them. Results. The present study shows high increase of the mean values of YM and height of RBC after 35 days of storage and decrease of the mean values of their diameter. Conclusion. Statistically significant high increase of the mean values of YM indicates the decrease of the elasticity of the cells in the course of storing of the RBC. This parameter along with the morphological characteristics can be used as criterion for assessment of applicability of the sRBC for blood transfusion.

Introduction: The satisfaction level with health care reflects the quality of care from the patient’s perspective. The aim of this study is to assess patient satisfaction with anesthesia care in a Portuguese general hospital by using the “The Heidelberg Peri-anaesthetic Questionnaire”. Material and Methods: The questionnaire was translated and tested based on psychometric quality criteria in a sample of 107 patients who underwent elective surgery as inpatients at Hospital de São João. The global satisfaction and for each dimension of care were calculated. We analyzed the differences between patients with different levels of satisfaction, identifying potential confounding factors. Results: The Portuguese version of the questionnaire has 32 items distributed in three dimensions: ‘staff’, ‘discomfort’ and ‘fear’. The mean values of satisfaction for each dimension were 83.4%, 66.8% and 65.9%, respectively. The internal consistence was demonstrated by a Cronbach’s alpha coefficient ranging from 0.776 to 0.875 in the three dimensions. Satisfied and dissatisfied patients differed in the three dimensions, but to a lesser degree in ‘staff’. In the multivariate analysis we found significant influence of gender in the ‘discomfort’ dimension. Discussion: The questionnaire has good psychometric characteristics. The domain ‘staff’ includes three domains of the source questionnaire. Conclusions: Its application revealed high satisfaction levels regarding the staff. Dissatisfaction was mainly seen in the “fear” and “discomfort” dimensions, the latter being significantly lower in males.

Abstract Background: The efficacy of epoetin beta (E) is well documented in clinical trials in anemic cancer patients (pts). This study was conducted to assess E use, efficacy, safety and effect on quality of life in cancer pts, in usual practice. Methods: This prospective, multicenter, longitudinal, observational French study assessed a 4-month follow-up of informed consent cancer pts (including both solid tumors (ST) and non-myeloid hematological malignancies (H)) treated with E for chemotherapy-related anemia. Data were collected between January 2005 and March 2006. We only present here the results of the H subgroup. Results: Among 2809 pts, 675 had an H including 325 non-Hodgkin lymphoma (NHL), 181 multiple myeloma (MM) and 80 chronic lymphocytic leukemia (CLL). 52% of pts received their first line of chemotherapy, 24% their second one. At inclusion, Hb levels were distributed as follows: < 9 g/dl: 32%, [9–11[ g/dl, 56%, [11–13[ g/dl, 11%. At inclusion, endogenous erythropoietin rate was monitored for only 8% of pts, ferritin was available for 32%, transferrin saturation for 17% and reticulocytes for 24%. At initiation, pts received a median dose of 30000 U/week of E on a once weekly regimen schedule for 98% of pts. E was associated with iron supplementation in 20% of pts (1% IV). The mean Hb level increased from 10 g/dl [5 – 14] at baseline to 13 g/dl [7 – 17] in the entire cohort of H pts, from 10 g/dl [5 – 14] to 12 g/dl [7 – 16] in NHL pts, from 10 g/dl [6 – 13] to 13 g/dl [8 – 17] in MM pts and from 10 g/dl [6 – 13] to 13 g/dl [7 – 17] in CLL pts. Hb response rate (RR) was 56% (CI95: 51 – 61) in H pts, 53% (CI95: 46 – 60) in NHL pts, 57% (CI95: 48 – 66) in MM pts and 56% (CI95: 41 – 70) in CLL pts. 41% of patients were transfused at inclusion or during the study. Good performance status (PS≤1) (OR=1.6, CI95: 1.1–2.5), non platinum-based regimen (OR=2.4, CI95: 1.2–4.9) and iron supplementation (OR=2.6, CI95: 1.4–5.1) are identified both in univariate and multivariate analysis as predictive factors of Hb response. The mean of FACT score improved from 29 (CI95: 26–31) at initiation to 36 (CI95: 34–38) at the end of study (p<0.0001). Thromboembolic events were reported in 2% of patients. Conclusion: These results confirm the efficacy and safety of epoetin beta in routine practice for anemic patients with a non-myeloid hematological malignancy receiving chemotherapy. Epoetin beta improves the quality of life measured by FACT score.
