Correlations between Bench-Scale and Large-Scale Extinction Metrics for Firefighting Foams

Locally weighted regressions (LWR) were calculated between MIL-PRF-24385 1.8 m diameter pool fire extinction results and various 19 cm pool fire metrics, as compiled in a recent database. The goal: to define correlations between bench and large-scale foam fire extinction experiments to improve bench-scale experiments to more rapidly screen the firefighting potential of environmentally-friendly foams. Bench-scale metrics included the area under the curve (AUC) for extinction time versus foam flow rate profiles, the average extinction times at binned foam flow rate ranges, and CO2-based extinction times, determined through tunable diode laser absorption spectroscopy (TDLAS) measurements above the pool fire. When cross-validation was implemented within the LWR algorithm, the AUC values, CO2-based extinction times, and extinction times for a flow rate-bin > 1500 ml/min showed the best correlations to large-scale data; however, the R2 values were all below 0.6, indicating a low level of correlation. Although differences between active versus passive firefighter and foam generation methods exist between the two scales, data accuracy and limited data are likely contributing the most to low R2 values. The LWR correlations are promising and can be improved with accurate data, providing confidence in bench-scale testing despite diminished radiation intensity and turbulence associated with larger fires.

Optimal quantum circuit generation for pixel segmentation in multiband images

A novel approach is proposed for multiband image processing via quantum models in real situations. Quantum circuits are automatically generated ad-hoc for each use case via multiobjective genetic algorithms. Using this universal method, image processing tasks such as segmentation can be carried out by considering the properties that constitute each pixel. The generated circuits present a low level of correlation between qubits, and thus can be considered quantum-inspired machine learning models. The effectiveness of this methodology has been validated by applying it to different segmentation use cases. Comparisons are made between optimized classical kernel methods and the generated quantum-inspired models to understand their behaviors. The results show that quantum models for multiband image processing achieve accuracies similar to those of classical methods.

Factors affecting the passing rate of licensure examination for teachers at Sulu State College

This study was a descriptive-correlational study that analyzed the perceptions on the factors affecting the passing rate of students in Licensure Exams for Teachers (LET) in Sulu State College (SCC). Quota sampling (n=100) was used to sample the participants from different school/college/departments in SCC. The primary participants were faculties from School of Education, School of Arts and Sciences, SSC Senior High School, SSC Laboratory High School, Other SCC departments with License for Public Teachers (LPT). A survey questionnaire was developed to elicit the responses from the faculty and staff with four scales—(i) Student-related factors, (ii) School-related factors, (iii) Home-related factors, and (iv) Teacher-related factors. Findings indicated that for SCC faculty and staff, the student-related factors, school-related factors, home-related factors, and teacher-related factors most likely influenced the student’s outcomes in LET. There were also significant correlations observed between the variables from high (home-teacher factors), moderate (student-school, home-school, teacher-school factors), and low (student-home, teacher-student factors) correlation levels. Recognizing the salience of student-related challenges, such as socio-economic backgrounds, motivation, and study habits, underscores the importance of providing targeted support mechanisms to address these issues. Similarly, focusing on enhancing school-related factors, such as curriculum design, teaching quality, and support services, can contribute to creating conducive learning environments conducive to students' success.

Anyone with A Charger? Correlation of Nomophobia, Leisure Boredom and Quality of Life in Youth at University

Aim: Along with affecting our daily lives and habits majorly, rapidly developing technology is known to increase the leisure boredom of youth in case they stay away from the technology. The fear of staying away from smartphones which is the most important material of portable technology is described as a recent disturbance and even a “a disorder of the modern world” (King et.al., 2010). In order for smartphones which have a significant place to meet the needs of life with aims such as pandemics, earthquakes etc. not to become an illness, it is important to investigate the reasons behind it. Considering these, the aim of the current study is to compare the digital game addiction, leisure boredom and quality of life of the students of Alanya Alaaddin Keykubat University in terms of different variables and to evaluate the correlation and effect sizes of these scales. Method: The study group consists of 405 university students (Meanage = 21.71± 4.13) studying at Alanya Alaaddin Keykubat University 239 of which are female (Meanage = 21.69± 4.30) and 166 of which are male (Meanage = 21.74± 3.88). As data collection tool, Leisure Boredom Scale (LBS) (Iso-Ahola & Weissinger 1990; Kara et.al, 2014), Nomophobia Scale (NFS) (Yıldırım & Correia 2015; Yıldırım et.al, 2016) and Quality of Life Scale – Short Form (QOL-SF) (Eser et.al, 2010) were used. In the analysis of the obtained data, descriptive statistics, t-test, ANOVA, Pearson Correlation and regression tests were used. To determine the reliability of scales, Cronbach Alpha intern coefficients were calculated. Findings: When the analysis results were evaluated, it is determined that there is a statistically significant difference in the total scores of LBS, NFS and QOL-SF in terms of “having difficulty in evaluating leisure”, “participation frequency in physical activity” and “evaluating oneself as smartphone addict”. Also, it is determined there is a statistically significant difference in the total scores of LBS and NFS in terms of “use of smartphone times/hour” (p<0.01). According to the Pearson correlation analysis, there is a positive and medium level correlation between NFS and LBS whereas there is a negative and low level of correlation between NFS and QOL-SF. Also, there is a negative and medium level of correlation between LBS and QOL-SF. The data showed that NFS has a negative impact on QOL-SF LBS has a negative impact on QOL-SF, and NFS has a positive impact on LBS. Conclusion: It is concluded that the group which has no difficulty in making use of leisure, who participates in physical activity regularly, who has less connection with their smartphones and who doesn’t see themselves as smartphone addicts have lower levels of leisure boredom perception and nomophobia whereas they have higher levels of quality of life. The fear of losing connections increases the level of boredom perception in students and it decreases the quality of life. Also, quality of life decreases due to the increase in boredom perception.

Correlating quadriceps patellar tendon angle and lateral patellar tilt angle in patients with irregular alignment: a cross-sectional study with retrospective data.

The newly defined angle, quadriceps-patella angle (QPA), reflects the combined force transmitted to the patella by the quadriceps muscles and patellar tendon. An increase in QPA may correlate with an increased force on the patella, which is significant in diagnosing patellofemoral instability and pain syndrome. In our study, we examined how various angles and pathologies vary depending on lateral patellar tilt angle (LPTA). QPA and patellar malalignment was investigated. Thus, the importance of understanding patellar malalignment and the research gap. Three hundred and fifty patients who underwent knee magnetic resonance imaging (MRI) examinations were included. The cross-sectional study conducted retrospectively between the years of 2018-2020 in a tertiary care outpatient clinic. Shapiro-Wilk normality, Chi-square, Mann-Whitney-U, Spearman correlation and receiver operating characteristic (ROC) curve analysis, statistical tests used for analysis. The patellar tendon length, patellar height, tibial tubercle-trochlear groove distance (TT-TG), patella angle, trochlear sulcus angle, trochlear groove depth (TGD), medial trochlea length (MT), lateral trochlea length (LT), medial trochlear/lateral trochlear length ratio (MT/LT), LPTA, patella-patellar tendon angle (PPTA), QPA, Insall-Salvati index (ISI), medial trochlear inclination (MTI), lateral trochlear inclination (LTI) were among these measurements. In addition, we aim to reveal whether there is a significant relationship between two important angles LPTA and QPA. Whether there is a significant increase in the development of chondromalacia for the patient group with LPTA >5°. We examined how the frequency of chondromalacia changes in the patient group with LPTA >5°. Two hundred and seventy seven patients included in the study and many measurements were performed on MRI. Fad-pad edema was found to be significantly higher in the group with LPTA <5° (P=0.046). TT-TG distance was significantly higher, TGD and MT were significantly lower in patients with higher LPTA (P=0.001, P=0.002 and P=0.017, respectively). A low level of significant positive correlation was found between QPA and patellar tendon length. There is no significant difference between QPA and PPTA angles between the groups with LPTA <5° and >5° (P=0.503, P=0.188). In the ROC analysis performed to determine the cut-off value, the LPTA value ≤14.2° which significantly predicted the presence of fad-pad edema, had the highest sensitivity and specificity [sensitivity: 76.71%, specificity: 39.90%, area under the curve (AUC): 0.588, P=0.024]. QPA is independent from many angles of the knee and does not change significantly. As the patellar tendon length increases, QPA angle also increases. In patients with abnormal LPTA, the frequency of TT-TG distance and chondromalacia increased, while TGD and MT decreased. Patients with a low LPTA can be more carefully examined for chondromalacia and fad-pad edema in clinical and MRI examination.

Agreement between Fetal Brain Ultrasonography and Magnetic Resonance Imaging in the Measurements of the Corpus Callosum and Transverse Cerebellar Diameter.

As the use of magnetic resonance imaging of the fetal brain has evolved, the need to understand its efficiency in the biometry of the fetal brain has broadened. This study aimed to assess the level of agreement and correlation between the two cardinal imaging methods of fetal neuroimaging, ultrasonography (US) and magnetic resonance imaging (MRI), by measuring the corpus callosum (CC) and transverse cerebellar diameter (TCD) in terms of length and percentile. Measurements of CC and TCD length and percentile were documented over a 7-year span in a tertiary referral medical center. All US and MRI examinations were performed in the customary planes and subcategorized by valid reference charts. Exclusion and inclusion criteria were set before the collection and processing of the data. A total of 156 fetuses out of 483 were included in the study. A positive, strong correlation and agreement were found (r = 0.78; ICC = 0.76) between US and MRI in TCD measurements. For CC length measurement, a moderate correlation and moderate agreement (r = 0.51; ICC = 0.49) between US and MRI was observed. TCD and CC percentiles had lower levels of correlation and agreement compared with the length variables. Our study indicates good agreement between MRI and US in the assessment of TCD measurement as a part of antenatal neuroimaging. Furthermore, while the two techniques are not always compatible, they are complementary methods.

Motives for Caffeine Consumption Questionnaire (MCCQ): validity and reliability of Turkish version

ObjectivesThe aims of this study are to make the Turkish validity and reliability of the scale that explain why caffeine intake. Additionally, it is crucial to highlight that the adaptation of the scale involved a confirmatory factor analysis (CFA) to validate its structure and the need for this adaptation in the Turkish context.Materials and methodsThe study was carried out with a total of 200 university students, comprised of 93.5% female and 6.5% male participants, with a mean age of 21.74 ± 6.15 years who were actively studying in the faculties of the universities who accepted to participate voluntarily in the study were included. The Turkish version of the Motives for Caffeine Consumption Questionnaire (MCCQ) scale and the MCCQ was used as the data collection tools. To evaluate the statistical analysis findings, the margin of error was taken as 5%. The entire application was carried out with the R-project software. CFA was used to test the adaptation of the MCCQ scale from English to Turkish.ResultsThe alpha internal consistency coefficient for the whole scale was calculated as 0.959. Just like the original scale, the Turkish version shows a six-factor structure: habit, alertness, mood, social, taste, and symptom management. In MCCQ-TR, it showed a low level of positive correlation with Yale Food Addiction Scale (YFAS). For the final scale with 23 items and 6 sub-dimensions, it was determined that the fit indices were at an acceptable level, and the internal consistency was highly reliable for all sub-dimensions and the total scale.ConclusionsIt has been determined that the Turkish version of the MCCQ is a valid and reliable measurement tool to operationalize the motives of caffeine consumption and to reveal possible differences in the motives regarding gender, age, and the type of caffeinated products consumed. The use of CFA in adapting the scale ensures the robustness of the structural validity in the Turkish context, making this adaptation a valuable contribution to the field.

The Correlation Study among EFL Learners’ Reticence, Motivation and Speaking Habit

This research aims to investigate the correlation between students' reticence, motivation, and their speaking habits which effected their speaking skills. The method used is a quantitative approach with a correlational design. The population was the eleventh-grade students of MA NW Montong Kubur comprising one class with a total of 35 students. The researcher used the total sampling method, in which all eleventh-grade students became respondents. Data collection was done through questionnaire and speaking test. The results showed that the correlation coefficient between students' speaking anxiety and their speaking achievement was r=0.312. Although these two variables have a negative correlation, the value of r=0.312 can still be classified as a significant correlation. Furthermore, the correlation coefficient between students' motivation and their speaking habits was found to be r=0.032. This means that there is a positive relationship between these variables, but the value of r=0.032 indicates a low correlation. Finally, the results showed that the correlation coefficient between students' speaking reticence, motivation, and speaking habits was r=0.105 which means that these three variables have a positive correlation, although the value of 0.105 indicates a very low level of correlation.

Tax Policy: Impact on Business Development and Economic Dynamics of the Country

"The optimal system, structure, and effectiveness of the tax system depend on many factors and are characterized by several differences depending on the country’s social and economic development. The purpose of the academic paper is to identify the features of the impact of the EU-27 countries’ tax policy on business development and economic dynamics to determine the differences in this correlation. Methodology. The statistical and regression analysis of the tax structure of the EU-27 countries is used in the scientific article to evaluate its correlation with economic dynamics for the period 2000-2022 based on the average values for the following periods: 2000-2005, 2006-2010, 2011-2015, and 2016-2022. The results demonstrate a slowdown in economic growth in the EU-27 in the long run from 2000 to 2019 and economic growth in 2021 to 2022 with no significant changes in the tax structure. The dynamics of tax revenues were revealed to be stable, despite their different shares in GDP. In general, it is possible to assert a low level of correlation between the share of tax revenues in GDP and the annual GDP growth rate. The established regression model shows only a 9% change in GDP dynamics depending on the change in the share of tax revenues to the budgets of the EU-27 countries. The research has identified three groups of countries by the share of tax revenues, by the share of taxes on income, profit and capital gains, and by the share of taxes on goods and services in the EU-27."

Correlations between p-wave velocity and SPT-N for saturated and unsaturated alluvial clays using dimensional analysis

The aim of this research is to establish practical and robust correlations between dilatational wave velocities (p-wave velocities, Vp) and the Standard Penetration Test blow count (SPT-N). Very low levels of correlation are recorded with the conventional single variable approaches, in consequence, a multivariable study is needed for higher precision. A dimensional analysis was conducted including other soil parameters that condition this physical phenomenon, such as the void ratio (e), the degree of saturation (Sr), the effective overburden pressure (σ′v), and the particle density (γs), for greater precision with Vp and SPT-N correlations. Over 100 seismic and SPT tests were performed around the coastal city of Juchitán de Zaragoza (Oaxaca), Mexico, to gather information for this research. As a result, two dimensionless indexes -DSIu (Undrained Dilatational Stiffness Index) and MDSIu (Modified Undrained Dilatational Stiffness Index)- yielded two alternative expressions between both indexes and Vp. In this way, a strong relationship between Vp and SPT-N was obtained with an adjusted coefficient of determination R2 value of 0.93.

Gowa but has a low level of relationship degree or weak correlation because it is negative, so it has an impact where the school literacy movement does not function at school due to lack of encouragement from teachers to use existing facilities, but beyond that students actually understand the existence of the school literacy movement but students rarely or even do not utilize existing facilities at school to increase interest in reading.

Effects of delayed diagnosis on tumor size, stage and grade in bladder cancer.

This study is planned based on the hypothesis that if bladder cancer is detected early, the disease would be less advanced and the possibility of treatment will increase, at least the recurrence-free survival will be longer. Regarding this hypothesis, it is aimed to investigate the effect of delayed diagnosis primarily on the disease factors. The study included 169 patients, who underwent TUR-BT with the suspicion of bladder cancer in the urology clinic of Afyonkarahisar Faculty of Medicine between April 2018 and April 2023. Demographic and clinical data of the patients were recorded and compared. It was observed that the delay in diagnosis was significantly longer in patients with tumors larger than 3cm compared to patients with tumors smaller than 3cm (p < 0.001). In the correlation analysis between tumor size, duration of diagnosis delay, age, T stage, and tumor grade, a low level of positive correlation was observed between tumor size and duration of diagnosis delay, and it was statistically significant (r = 0.215, p = 0.005). In our study, it was shown that the tumor size increases as the duration of diagnosis delay increases and this increase causes an increase of 0.088mm in the pathological size of the tumor in the 1-day delay period. Considering that tumor size changes the risk group of the disease in bladder tumors, and relatedly the follow-up and treatment process changes, we believe that these data will be valuable in the management of bladder cancer.

The Relationship among Patient Satisfaction, Patient Loyalty, and Compliance with Treatment

This study examined the relationship between patient loyalty and adherence to treatment and evaluated the mediating role of patient satisfaction in this relationship. This study consisted of 386 participants. Correlation and regression analyses were used. A low level of positive correlation was found between loyalty and compliance scores. It was determined that satisfaction did not mediate the relationship between loyalty and compliance. In addition, a moderately positive relationship was found between loyalty and satisfaction. It has been observed that patient loyalty can play a critical role in important health outcomes such as adherence to treatment and increasing satisfaction.

Factors determining shopping and selection of retail store outlets, A study

Retail business is in the limelight nowadays. Not only are their margins getting bigger but also are the sizes of the outlets. To intrude into the retail industry a questionnaire was designed wherein the following questions were asked. First of all the factors that drive customers to shop at certain and particular stores over others in the retail industry of Goa were looked into. Secondly, if there was any correlation between store digitization and consumer buying satisfaction. Thirdly, if there was any correlation between consumer buying behavior and brand loyalty. And lastly if there was any correlation between retail discount and consumer footfall. The findings were as follows: nearness to the residence was ranked number 1, followed by quality of the product, assortment of merchandise, ambience, discounts given and knowledgeable staff in the store. A low level of correlation existed between digitalization and consumer buying satisfaction, a high level of correlation existed between consumer buying behavior and brand loyalty and a high correlation existed between retail discount and store reputation.

Use of GNSS and ERA5 precipitable water vapor based standardized precipitation conversion index for drought monitoring in the Mediterranean coast: A first case study in Southern Spain

In this paper the Standardized Precipitation Conversion Index (SPCI), a PWV-based drought index, has been computed using GNSS and ERA5 PWV and its performance has been tested with respect to the Standardized Precipitation Evapotranspiration Index (SPEI) in Southern Spain. One of the climatic features of this area is the low correlation level between PWV and precipitation, in contrast with other areas in which SPCI has been previously tested. The GNSS-SPCI has been derived from validated ZTD time series estimated from local GNSS permanent stations’ data. All the needed meteorological values were derived from ERA5, excepting precipitation values and SPEI-SPI values which were extracted from a national high-resolution dataset.The resulting SPCI time series have shown high correlation coefficients with respect to the SPEI. The use of longer SPCI time series allowed by ERA5 model has provided the most coherent results, suggesting that the ERA5-PWV data can be interesting to overcome problems caused by the short timespan of GNSS time series in SPCI computation. In general, high correlation coefficients have been obtained compared to global results from previous studies. This shows that, even for regions with low correlation levels between PWV and precipitation, the SPCI can have an interesting potential for drought monitoring. The SPCI was found to perform better on higher timescales (12 and 24 months). The performance of SPCI has also been compared that of the SPI: SPCI is able to outperform SPI for the 24-month timescale for a limited geographical region. This supports that the inclusion of PWV data in drought monitoring indices could be promising and is worth keeping to be investigated.

Interpretation of odor complaint records with BTEX pollutants and meteorological factors: Çorlu case study

Air pollution in urban areas increases as a result of emitted air from different sources within the mixing layer of troposphere. Odor pollution is amongst the primary reasons behind environmental nuisance and occurrence of citizen complaints. Frequent exposure to odorous compounds and/or odor nuisance are increasingly associated with air pollution problems. Besides, there is no universally accepted environmental odor management method reported so far. Level of air pollutants emission, distance of emission sources to residential areas, to-pography, geographical and meteorological conditions have influence on imposed level of air pollution and odor pollution in cities.&#x0D; &#x0D; This study is built on the citizen odor complaint data (based on frequency, intensity, duration, odor tone and location (namely the FIDOL factors) collected in Çorlu/Tekirdağ through the GIS integrated public participated platform, namely the Çorlu KODER mobile application. The annual odor complaint data was briefly introduced and given an evaluation with the mo-bile app users demographic information. The obtained data between August 28-November 2 of 2021, was subjected to interpretative evaluation and statistical analysis with BTEX (benzene, toluene, ethylene benzene and xylen) concentrations, inorganic air pollution concentrations and meteorological factors. In light of the obtained results, temperature, wind speed, relative humidity and toluene concentration were found to play a significant role on the number of citizen odor complaints. The EU reported limit value, lower rating threshold and upper rating threshold for BTEX pollutants have been exceeded several times.&#x0D; &#x0D; The average Toluene/benzene ratios obtained during the study show that; non-traffic sources contribute significantly to VOC emissions. Air pollutants transportation mechanism from neighbouring OIZ settlements become a prominent justification and support the hypothesis that residential areas of Corlu are under the effect of industrial air pollution and odor pollution con-stituents. There is low level of negative correlation between the benzene measured in Çorlu and WS (r=-0.63). Below 2.4 m/s, the average number of odor complaints (ANOC) tend to increase, while above this level odor complaints are diminished). The ANOC remained around 4 for[C] &lt; 4 ug/m3 and reached to 18 for [C]BTEXtotal &gt; 8 ug/m3. Above [C]Toluen=3 ug/m3 conditions, Daily ANOC increase from 7 to 19. Over [C]Toluen= 4 ug/m3 conditions, it reached up to 23. Increses in the number of daily ANOC by temperature is distinct over 21 C0 and reaches to 35. &#x0D; &#x0D; The GIS integrated citizen complaint collection platforms are critical for real-time data collection of environmental complaints with high spatiotemporal accuracy. Citizen odor complaint surveys are useful monitoring tools and obtained data sets can be used to identify sensitive areas where and when specific actions should be taken and air pollutants measuement studies be performed.

Identification of Students' Online Learning Readiness (KBO) in the Post-Pandemic Period

This study aims to identify online learning readiness (KBO) students of FKIP University of Mataram. This type of research is quantitative with a descriptive approach. The study used a KBO questionnaire instrument which was compiled with a scoring system. Analysis of the data used is the Pearson product moment correlation to see the correlation between KBO scores and academic abilities possessed by students. The results showed that students' online learning readiness (KBO) was at a score of less than 80, meaning that students' online learning readiness was still not very good. Meanwhile, according to the Pearson product moment correlation data analysis, it shows that the student correlation value from JIP is 0.815. For students from JMIPA it is 0.10. Meanwhile, students from JPBI and JIPS got a correlation value of 0.386 and 0.59. Based on these data, it can be concluded that JIP and JIPS students have a strong correlation between academic ability and students' KBO scores. While JMIPA and JPBI, students' academic ability and KBO scores have a low level of correlation.

Profitability and Cost Analysis for Contract Broiler Production in Turkey

This study uses the data obtained from 63 broiler farms engaged in contract farming in Akhisar, Turkey. The average feed conversion ratio in the broiler farms is 1.75, the average live weight 2.25 kg, and the mean market age 38.9 days. The feed conversion rate and the income generated are highly correlated (r = −0.76). The production index is 313.4. According to this production index value, 47.6% of the enterprises are below the average production index. It is highest when the marketing age is greater than 38 days, less than and equal to 40. In other words, it is the optimum market age range where carcass yield is at maximum. The average mortality rate is 4.68%. In 52.4% of the enterprises, the mortality rate is above 5%. There is a low level of correlation between the mortality rate and income (r = −0.26). In broiler farming, mortality rate, and feed conversion ratio are factors that directly affect the success and income of the breeder. In broiler farming, the heating cost has the largest share of the total cost, followed by the litter cost. They are followed by labor, electricity, and pesticide costs. Variable costs account for three-quarters of the total operating costs. The farms have a mean gross value of production of $23.797 per m2 and $1.400 per broiler in a breeding period. The profit margin is 0.572 $/kg per broiler. The mean enterprise net income in the breeding period is $9.197 per m2 and $0.541 per broiler. These findings suggest that broiler farming is a profitable venture.
