An Efficient Approach for Uncertain Event Detection in RFID Complex Event Processing

The globalization of manufacturing has increased the risk of counterfeiting as the demand grows, the production flow increases, and the availability expands. The intensifying counterfeit issues causing a worriment to companies and putting lives at risk. Companies have ploughed a large amount of money into defensive measures, but their efforts have not slowed counterfeiters. In such complex manufacturing processes, decision-making and real-time reactions to uncertain situations throughout the production process are one way to exploit the challenges. Detecting uncertain conditions such as counterfeit and missing items in the manufacturing environment requires a specialized set of technologies to deal with a flow of continuously created data. In this paper, we propose an uncertain detection algorithm (UDA), an approach to detect uncertain events such as counterfeit and missing items in the RFID distributed system for a manufacturing environment. The proposed method is based on the hashing and thread pool technique to solve high memory consumption, long processing time and low event throughput in the current detection approaches. The experimental results show that the execution time of the proposed method is averagely reduced 22% in different tests, and our proposed method has better performance in processing time based on RFID event streams.

A Novel Approach for More Effective Emergency Equipment Storage: The Task-Based Package-Organized Neonatal Emergency Backpack

Objectives: To evaluate a new task-based package-organized (TPO) neonatal emergency backpack and to compare it to the classical (ABC- and material-based) backpack.Methods: Simulation-based assessment of time to retrieve equipment for three different tasks [intraosseous access (IO), intubation and adrenaline administration] using the TPO and the classical emergency backpack was compared.Results: Equipment retrieval times for the three tasks were assessed for 24 nurses (12 intermediate care, 12 intensive care) and were significantly faster in the TPO than in the classical backpack (IO 33 vs. 75 s, p < 0.001; intubation 53 vs. 70 s, p = 0,001; adrenaline 22 vs. 45 s, p < 0.001). The number of missing items was significantly lower using the TPO backpack for IO and adrenaline retrieval (IO 0,9 vs. 2,3 items, p < 00001, adrenaline 0.04 vs. 1, p < 0.001) but not for intubation equipment (0.9 vs. 1, not significant). The subjective rating of overall clearness was significantly higher for the TPO compared with the classical backpack (5,9 vs. 3,5, p < 0.001).Conclusion: Task-based package organization of neonatal emergency backpacks is feasible and might be superior to ABC-/material-oriented storage.

Validation of the Thai version of the Prolapse and Incontinence Knowledge Questionnaire (PIKQ)

Introduction and hypothesis The Prolapse and Incontinence Knowledge Questionnaire (PIKQ) was developed and validated to assess women’s knowledge regarding etiology, diagnosis and treatment of pelvic organ prolapse (POP) and urinary incontinence (UI). We aimed to translate and validate a Thai version of the PIKQ to use as a tool to evaluate knowledge of POP and UI among Thai-speaking women. Methods The English PIKQ, which comprises the PIKQ-POP and PIKQ-UI sections, was translated into Thai. Psychometric properties of the final version of the Thai PIKQ were tested for content validity, construct validity, internal consistency and test-retest reliability among 168 women attending a gynecology clinic and 150 nurses. Results Regarding content validity of the final Thai PIKQ, the number of missing items was 0. Participants in the nurse group were more likely than those in the patient group to select the correct answer for all items for the POP scale and UI scale (P < 0.001). For internal consistency testing, Cronbach’s alpha coefficient was 0.745 for the PIKQ-POP and 0.754 for the PIKQ-UI scales, suggesting that the items had relatively high internal consistency. The item-total correlation values ranged from 0.204 to 0.539, showing an adequate correlation of each item with the scale overall. The correlation coefficients between the test and retest for PIKQ-POP and PIKQ-UI were 0.685 and 0.735, respectively (P < 0.001). Conclusions The Thai PIKQ is a simple instrument which shows good validity and high reliability and could be a useful tool for assessing knowledge regarding POP and UI in clinical practice.

Is assessment of oral health-related quality of life burdensome? An item nonresponse analysis of the oral health impact profile

Aim This study aimed to investigate if in the 49-item Oral Health Impact Profile (OHIP): (i) more missing data occurred when participants answered more questions, (ii) more missing data occurred in a particular item or set of related items, and (iii) item missingness was associated with the demographic characteristics and oral health-related quality of life (OHRQoL) impairment level. Methods We used OHIP data from the Dimensions of OHRQoL (DOQ) project, which consolidated data from 35 individual studies. Among these studies, we analyzed OHIP data from 19 studies (4,847 surveyed individuals, of which 3,481 were completed under supervision and 1,366 were completed unsupervised) that contained some missing information. We computed descriptive statistics to investigate the OHIP missingness. We also used logistic regression analyses, with missing information as the dependent variable, and number of questions filled in (OHIP item rank) as the independent variable for samples with and without supervision. To investigate whether missing data occurs more in a particular item or set of related items we fitted regression models with individual OHIP items and the OHRQoL dimensions as indicator variables. We also investigated age, gender, and OHRQoL level as predictor variables for missing OHIP items. Results We found very low levels of missingness across individual OHIP items and set of related items, and there was no particular item or set of related items that was associated with more missing data. Also, more missing data did not depend on whether the participants answered more questions. In studies without supervision, older persons and females were 5.47 and 2.66 times more likely to have missing items than younger persons and females. However, in studies with supervision, older persons, and participants with more OHRQoL impairment were 1.70 and 2.65 times more likely to have missing items. Conclusion The study participants from general and dental patient populations did not find OHIP-49 burdensome. OHIP item missingness did not depend on a particular OHIP item or set of related items, or if the study participants responded to a greater number of OHIP items. We did not find a consistent pattern of the influence of sociodemographic and OHRQoL magnitude information on OHIP missingness. The amount of missing OHIP information was low making any potential influence likely small in magnitude.

Effects of a conservative in-patient voice treatment on the voice-related self-concept

Purpose Observational study to determine if the voice-related self-concept as measured via the Fragebogen zur Erfassung des Stimmlichen Selbstkonzepts FESS (questionnaire for the assessment of the voice self-concept) can be improved through in-patient voice therapy. Methods 234 female and 80 male patients that underwent an intensive 3- to 4-week in-patient voice treatment due to varying types of dysphonia. After imputation of missing items but not missing questionnaires, 255 patients were eligible for FESS evaluation, 313 for VHI-12 evaluation. The German questionnaire for the assessment of the voice self-concept (FESS) and the German 12-item short-form of the Voice Handicap Index (VHI-12) were administered at the beginning and at the end of the hospital stay. Before–after comparisons are made visually and via t test. Results The Voice Handicap was significantly reduced, demonstrating the effectiveness of the administered therapy. Of the three scales of the FESS, the relationship with one's own voice and the awareness of the use of one's own voice was increased and thus improved. The connection between voice and emotional changes decreased significantly but only slightly. Conclusion Conservative voice rehabilitation can not only reduce the voice handicap, but also improve the voice self-concept and the results can be measured.

Development of Preschoolers’ Understanding of Zero

While knowledge on the development of understanding positive integers is rapidly growing, the development of understanding zero remains not well-understood. Here, we test several components of preschoolers’ understanding of zero: Whether they can use empty sets in numerical tasks (as measured with comparison, addition, and subtraction tasks); whether they can use empty sets soon after they understand the cardinality principle (cardinality-principle knowledge is measured with the give-N task); whether they know what the word “zero” refers to (tested in all tasks in this study); and whether they categorize zero as a number (as measured with the smallest-number and is-it-a-number tasks). The results show that preschoolers can handle empty sets in numerical tasks as soon as they can handle positive numbers and as soon as, or even earlier than, they understand the cardinality principle. Some also know that these sets are labeled as “zero.” However, preschoolers are unsure whether zero is a number. These results identify three components of knowledge about zero: operational knowledge, linguistic knowledge, and meta-knowledge. To account for these results, we propose that preschoolers may understand numbers as the properties of items or objects in a set. In this view, zero is not regarded as a number because an empty set does not include any items, and missing items cannot have any properties, therefore, they cannot have the number property either. This model can explain why zero is handled correctly in numerical tasks even though it is not regarded as a number.

OP0077 THE EMERGING EULAR NETWORK (EMEUNET): AN INTERNATIONAL SURVEY REFLECTING ON A TEN-YEAR JOURNEY

Background:The Emerging EULAR NETwork (EMEUNET), founded in 2009, aims to promote education, foster research collaborations and facilitate the integration of young researchers and rheumatologists within EULAR.Objectives:After 10 years, we aimed to interview our members to assess how EMEUNET is fulfilling its goals, understand if there are unmet needs and explore new ideas.Methods:In July 2019 a survey was circulated for 3 months among EMEUNET members via its social media channels. The survey contained 18 closed and 2 open items, in addition to general questions on age, job and country of origin and work.Results:Out of 124 total respondents, most completed all items (120/124) and only a minority had some missing items (4/124). A little over half of the respondents were female (n=69, 54.8%) and median age was 33y (range 25y-42y). Most respondents were born (n=109, 88.6%) and/or worked in Europe (n=114, 92.7%) (fig. 1), although there was also a representation from extra-European countries, which is in line with the general EMEUNET membership (https://emeunet.eular.org/map.cfm).Figure 1.Country of origin and where respondents work at the time of completing the EMEUNET VISE questionnaire.11 (9.1%) had been EMEUNET members for less than 2 years, 81 (66.9%) for 2-5years and 29 (24.0%) for more than 5 years.Figure 2 shows a clear link between the respondents’ perception of EMEUNET aim(s) and the actual aims of EMEUNET set out in our mission statement (https://emeunet.eular.org/mission_statement.cfm).Figure 2.The links between what participants would like to see as EMEUNET aims and the aims of EMEUNET as they are nowMost of the respondents got to know about EMEUNET through a friend/colleague in Rheumatology (n=67, 54.0%), at EULAR/ACR annual conferences (n=32, 25.8%), via social media (n=9, 7.3%), other international meeting (n=6, 4.8%), national Rheumatology meeting (n=6, 4.8%) or via the EMEUNETs country liaisons (n=4, 3.2%).29 respondents (24%) were part of the EMEUNET working group (WG), 43% (n=53) applied before to be part of the WG, 24% (n=29) never applied and 15% (n=19) did not know what the WG was. Most of the respondents who never applied to the WG thought it to be too time consuming. Only 21 (16.9%) felt there was a subgroup in the WG missing and most of those (n=8, 38.1%) found this should fully focus on research collaborations, which is actually part of the general aims of EMEUNET and a focus of all Working Groups.Only a relatively small portion of EMEUNET of respondents (<5%) stated to have approached EMEUNET with their ideas. Although 90.2% (n=110) felt that the opportunity to submit new ideas is a good initiative, only 52.5% (n=..) knew that such possibilities exists. This suggests that EMEUNET could do more to make members aware of this possibility. Additionally, while the main reasons for not contacting EMEUNET with an idea were ‘not having one’ (41.9%) or having ‘no time’ (34.9%), 20.9% feels their ideas would not be received well, which is another aspect offering room for improvement.Twice a year, EMEUNET organises networking events (NE) for their members to discuss their work in an informal setting. We found that 56/120 (46.7%) of the respondents prefer a low-budget (<€20) event, including an activity and the possibility to network, accompanied by drinks and bites. This is much in line with EMEUNETs past NE. In addition, past NEs were often mentioned as an example of ideal events.Conclusion:Awareness on EMEUNET often comes from colleagues and international conferences in rheumatology, which coincides with one of the focuses of EMEUNET to increase visibility in the last 10 years. Expectations about NE are in line with the previously organised NE.Areas for improvement are dissemination of information on the EMEUNET WG, the possibility to submit ideas -which is open to all members- and the increased focus on research collaboration, an aspect on which we are actively working as EMEUNET is fully engaged with the newly launched EULAR Virtual Research Centre.Disclosure of Interests:None declared

Feasibility and Concurrent Validity of Cerebral Palsy Quality of Life for Children (CP QOL-Child) in Thai Version

Background: The Cerebral Palsy Quality of Life for Children (CP QOL-Child) questionnaires are condition-specific QOL measures for children with CP focusing on perspectives of children with CP on their quality of life, not on their physical difficulties. The perspectives of well-being are core concepts of quality of life. The CP QOL-Child has already been translated in Thai and the reliability is excellent. The validity after the translation has not been conducted and is required. therefore, it is needed to examine the validity to ensure the clinical practicality. Objective: To examine feasibility and concurrent validity of the CP QOL-Child (Thai version). Materials and Methods: Eighty-five primary caregivers of 4- to 12-year-old children and 65 children between 9- and 12-years-old, who passed the inclusion criteria, completed three questionnaires including the CP QOL-Child (Thai version), the PedsQL 4.0 Generic Core Scales, and the PedsQL 3.0 CP module (Thai version). Results: For feasibility of the CP QOL-Child, no missing items were found in any items for the child self-report. For parent proxy report, missing items were scattered and from 1.2% to 7.1%. For concurrent validity, according to the total scores of both versions, the self-report and the parent proxy, the correlation coefficients between CP QOL-Child and PedsQL 4.0 Generic Core Scales were 0.23 to 0.25 meaning no or little correlations, at significance level of 0.05. The correlation coefficients between the CP QOL-Child and the PedsQL CP module were 0.38 to 0.49, meaning fair correlations, at significance level of 0.01. Conclusion: The feasibility of the CP QOL-Child (Thai version) was reportedly acceptable. The concurrent validity support that the CP QOL-Child may not measure the quality of life at the same constructs as the PedsQL. The CP QOL-Child asks the client’s perspectives of quality of life (QOL) while both PedsQL modules ask the client’s difficulties that might relate to QOL.

Study of regional stability by amplitude-frequency method

Interregional integration is the most important factor in the transformation of the national model of economic development. It facilitates the transition from a resource-based economy to an economy targeted at an innovative way of development. Such transformations promote an increase of competitiveness of the Russian economy. In this regard, the assessment of the level of interregional integrational interaction is an urgent task. The development of the theory and methodology of study of interregional economic integration processes, the development of mechanisms for assessing the instrumental and functional potential of interregional integration as a driver of the socio-economic development of partner regions for its improvement make it possible to replenish missing items in investigating the subject area under consideration. The new scientific results obtained in the paper on determining the indicators of interregional economic integration, characterizing the amplitudes of fluctuations in the value of the average per capita income in the regions of the Southern Federal District, develop a methodology for analyzing and forecasting the behavior of complex socio-economic systems and can act as a conceptual basis for creating a modernized instrumental and methodological apparatus for quantitative assessment, further formalized presentation and modeling of interregional interaction and substantiation of development directions and increasing the efficiency of interregional economic integration processes.
