In-situ empirical validation of common indoor climate parameters in an inhabited multizone dwelling

Combined building indoor climate and energy simulation models only recently gained vast popularity and their application has been moving from the research community to a broader audience. Yet, in-situ empirical validation of this new generation of complex multi-purpose dynamic simulation models has lagged behind. Using a dynamic multizone building indoor climate and energy simulation model in Modelica with the IDEAS library and buoyancy driven airflow components (validated with CONTAM), this research presents model validation results and lessons learned from an in-situ empirical validation study of common indoor climate parameters (i.e., indoor air temperature (), relative humidity (RH) and CO2 concentration (CO2)) for an inhabited and mechanically ventilated case study dwelling in The Netherlands. The simulation results show that the latest generation of building indoor climate and energy models in Modelica have great ability to accurately predict common indoor climate parameters in multizone inhabited dwellings (provided that user behavior info is available). Evaluation metrics for the three studied parameters show excellent calibration criteria (i.e., MAE between 0.60–0.78 °C (), 3.5–4.6% (RH) and 88–181 ppm (CO2)) and the accompanying graphs corroborate the findings. In the event that no motion sensor data is available, statistically generated occupancy profiles prove good representative alternatives on the condition that basic info is available about the number of inhabitants and the inhabitants’ lifestyle. In-situ monitoring for empirical model validation proves to be a real challenge full of (un)foreseen obstacles.

Creating a Policy for Coverage of Lymphatic Surgery: Addressing a Critical Unmet Need.

This article describes the key stakeholders and process involved in developing an insurance policy in the United States to establish medical necessity criteria for lymphatic surgery procedures. Lymphedema is a chronic health issue that impacts over 1.2 million patients and is associated with lifelong health, economic, and psychosocial costs. Patients affected have been described as "medical nomads," as they often interface with multiple providers before receiving an accurate diagnosis and treatment. This underscores the lack of attention and understanding about this disease across all sectors of the medical system. Unlike nations including Sweden and the United Kingdom, which provide insurance coverage for treatment, the United States has lagged behind. As a country, we have neglected to fully recognize the consequences of inadequate treatment of lymphedema, including chronic morbidities such as loss of mobility, psychosocial sequelae, recurrent infections, and even death. Recently, the authors' lymphatic center had the unique opportunity to help develop a policy that merged their clinical experience, recently established lymphatic care center of excellence criteria, and third-party payer policy expertise. This experience spanned 1 year from June of 2018 to June of 2019. The authors identify how key partnerships helped fill evidentiary gaps that ultimately resulted in policy change.

Grading Criteria of Anthurium DUS Quantitative Characteristics by Multiple Comparison.

The determination of the grades and interval of quantitative characteristics is an important job while we draft new distinctness, uniformity and stability (DUS) test guidelines. Grading criteria should be adjusted because of the effect of year and site; it is also a key task to establish applicable criteria in the DUS test. Excellent criteria will improve the accuracy of the DUS evaluation. In this study, we analyzed the variability and distribution patterns of nine quantitative characteristics of 251 anthurium varieties. Three methods were used to establish the grade criteria: the two standard deviation methods, the two LSD0.05 methods and the multiple comparison method. The results showed that the coefficient of variation within varieties varied from 6.96% to 10.11%. The quantitative characteristics observed in this study did not follow a normal distribution, except spadix thickness at the middle and spathe size. In most characteristics, the standard deviations and LSD0.05 were similar, except for spathe size. The state interval set by multiple comparison methods for every characteristic was variable, and its mean was about 1.25 times that of the other two methods. The process of establishing grading criteria using the multiple comparison method was simpler, and the criteria were more accurate, with a lower error rate.

Development and Evaluation of a Pragmatic Measure of Adherence to Dialectical Behavior Therapy: The DBT Adherence Checklist for Individual Therapy.

This paper presents two studies conducted to develop and evaluate a new pragmatic measure of therapist adherence to Dialectical Behavior Therapy (DBT): the DBT Adherence Checklist for Individual Therapy (DBT AC-I). Study 1 used item response analysis to select items from the gold standard DBT Adherence Coding Scale (DBT ACS) using archival data from 1271 DBT sessions. Items were then iteratively refined based on feedback from 33 target end-users to ensure relevance, usability, and understandability. Study 2 examined the psychometric properties of the DBT AC-I as a therapist self-report and observer-rated measure in 100 sessions from 50 therapist-client dyads, while also evaluating predictors of therapist accuracy in self-rated adherence. When used as a therapist self-report measure, concordance between therapist and observer ratings was at least moderate (AC1 ≥ 0.41) for all DBT AC-I items but overall concordance (ICC = 0.09) as well as convergent (r = 0.05) and criterion validity (AUC = 0.54) with the DBT ACS were poor. Higher therapist accuracy was predicted by greater DBT knowledge and adherence as well as more severe client suicidal ideation. When used by trained observers, the DBT AC-I had excellent interrater reliability (ICC = 0.93), convergent validity (r = 0.90), and criterion validity (AUC = 0.94). While therapists' self-rated adherence on the DBT AC-I should not be assumed to reflect their actual adherence, some therapists may self-rate accurately. The DBT AC-I offers an effective and relatively efficient method of evaluating adherence to DBT when used by trained observers.

Social capital and support from stakeholders, as well as community leaders, were found to strengthen community readiness for sustainable eco-health prevention and control of dengue fever.

Insurance Company Financial Performance Analysis

This study intends to examine the financial performance of insurance companies listed on the Indonesia Stock Exchange (IDX) between 2016 and 2019. This study employs the liquidity ratio, the profitability ratio, and the solvency ratio as indicators of financial performance. The sample comprises of thirteen insurance companies that are listed on the IDX and go public. The results revealed multiple findings. First, the liquidity ratio, which consists of the current ratio and the fast ratio, demonstrates fluctuations, particularly in the calculation of the current ratio. The maximum value for insurance companies with the AHAP code is 772 percent, which is included in the excellent criteria. In contrast, the insurance company with the code AMAG has the lowest value, 2%, which falls under the unfavorable criteria. The fast ratio also demonstrates positive results, with insurance companies having values greater than 1, indicating the availability of current assets to cover liabilities. The second variable is the solvency ratio, which comprises the total debt to equity ratio and the total debt to asset ratio. The insurance companies with the ASDM code have the highest total debt to equity ratio, which is 50%, indicating a solid equity-based return rate. Meanwhile, insurance companies with the AHAP code have the lowest value, 2%, indicating a weak equity-based return rate. The total debt to asset ratio is unfavorable, with insurance companies with the ASDM code having the highest value (83%) and insurance companies with the AHAP code having the lowest value (4%). Thirdly, return on assets (ROA) is used to compute the profitability ratio. ROA also fluctuates. Insurance companies with the AHAP code have the highest value, 5403%, which demonstrates the company's ability to generate exceptional returns on total assets. In contrast, insurance companies with the codes ABDA, AHAP, and AMAG have the lowest value, 6%, indicating a healthy rate of return on profits based on total assets.

Implementation of Digital-Based Authentic Assessment to Assess Observing, Inferring and Predicting Skills in Prospective Chemistry Teachers

As the spearhead of successful learning in the classroom, a prospective teacher must have qualified abilities and skills, teacher competence and teaching quality need to be ensured. One of the ways to measure the competence of prospective chemistry teachers is by using authentic assessments. This assessment can be done digitally through an authentic digital-based assessment with a project-based learning model. The model, research design and instrument development carried out in this study is an adaptation of the test preparation procedure with the following instrument preparation steps: (1) planning the test, (2) trying out the test, (3) establishing test validity, (4) establishing test reliability, (5) interpreting the score. In this study, there were three parameters studied, namely (1) Analysis of the needs of prospective teachers at school. (2) Preparation of authentic assessment instruments that have been developed based on validators, (3) Analysis of observing, inferring and predicting skills. Analysis of school needs is the basis for the preparation of authentic assessment instruments and models that are compiled. The results of the learning instruments that have been compiled and have been developed have excellent quality criteria with an average per aspect of 0.875 and are declared valid based on the assessment of material experts, media experts and peer reviewers. The validated instrument is then implemented where the Implementation Analysis on prospective teachers in the observing aspect gets a score of 3,374 including in the excellent category, as for inferring, it gets a score of 3,217 including in the good category, in the predicting aspect it gets a score of 3,553 including the excellent category, so that the average teacher candidate gets a score of 3,392 including the excellent category. Meanwhile, the affective instrument of students got a score of 3.22 on the persistence aspect and 3.16 on the attention aspect, both of which were in the good category. So that the average affective aspect of the participants got a score of 3.19 and was included in the good category

Digital capital and belonging in universities: quantifying social inequalities in the Philippines

This study examines social inequalities in Philippine universities that were exacerbated during the COVID-19 pandemic. A quantitative approach using a national sample of 677 university students was utilized to measure the mediating role of digital capital on social inequalities associated with belonging to academic spaces. For the purpose of determining direct and indirect impacts, structural equation modeling (SEM) was employed. Sociodemographic (i.e., gender, age, type of residence, and family income) and educational (i.e., type of university, year in the university, and excellence criterion) characteristics were the direct predictors that were examined as exogenous variables for both digital capital and belonging. Results indicate that type of residence (β=0.200, p<0.05), family income (β=0.220, p <0.001), and excellence criterion (β=0.271, p <0.01) are major determinants of digital capital. The model also shows that belonging is significantly predicted by age (β=0.087, p <0.05), family income (β=-0.207, p <0.001), and digital capital (β=0.576, p <0.001). Lastly, the findings reveal that the impacts of type of residence (β=0.116, p <0.05), family income (β=0.127, p <0.001), and excellence criterion (β=0.156, p <0.001) on belonging are successfully mediated by digital capital. These results suggest that there are indeed differences in students’ abilities to accumulate digital capital and that digital capital enhances the sense of belonging to and together in academic spaces for certain groups.

SAIL study of stroke, systemic embolism and bleeding outcomes with warfarin anticoagulation in non-valvular atrial fibrillation (S4-BOW-AF).

In patients with non-valvular atrial fibrillation (NVAF) prescribed warfarin, the association between guideline defined international normalised ratio (INR) control and adverse outcomes in unknown. We aimed to (i) determine stroke and systemic embolism (SSE) and bleeding events in NVAF patients prescribed warfarin; and (ii) estimate the increased risk of these adverse events associated with poor INR control in this population. Individual-level population-scale linked patient data were used to investigate the association between INR control and both SSE and bleeding events using (i) the National Institute for Health and Care Excellence (NICE) criteria of poor INR control [time in therapeutic range (TTR) <65%, two INRs <1.5 or two INRs >5 in a 6-month period or any INR >8]. A total of 35 891 patients were included for SSE and 35 035 for bleeding outcome analyses. Mean CHA2DS2-VASc score was 3.5 (SD = 1.7), and the mean follow up was 4.3 years for both analyses. Mean TTR was 71.9%, with 34% of time spent in poor INR control according to NICE criteria.SSE and bleeding event rates (per 100 patient years) were 1.01 (95%CI 0.95-1.08) and 3.4 (95%CI 3.3-3.5), respectively, during adequate INR control, rising to 1.82 (95%CI 1.70-1.94) and 4.8 (95% CI 4.6-5.0) during poor INR control.Poor INR control was independently associated with increased risk of both SSE [HR = 1.69 (95%CI = 1.54-1.86), P < 0.001] and bleeding [HR = 1.40 (95%CI 1.33-1.48), P < 0.001] in Cox-multivariable models. Guideline-defined poor INR control is associated with significantly higher SSE and bleeding event rates, independent of recognised risk factors for stroke or bleeding.

The Use and Efficacy of FFR-CT: Real-World Multicenter Audit of Clinical Data With Cost Analysis

BackgroundFractional flow reserve–computed tomography (FFR-CT) is endorsed by UK and U.S. chest pain guidelines, but its clinical effectiveness and cost benefit in real-world practice are unknown. ObjectivesThe purpose of this study was to audit the use of FFR-CT in clinical practice against England’s National Institute for Health and Care Excellence guidance and assess its diagnostic accuracy and cost. MethodsA multicenter audit was undertaken covering the 3 years when FFR-CT was centrally funded in England. For coronary computed tomographic angiograms (CCTAs) submitted for FFR-CT analysis, centers provided data on symptoms, CCTA and FFR-CT findings, and subsequent management. Audit standards included using FFR-CT only in patients with stable chest pain and equivocal stenosis (50%-69%). Diagnostic accuracy was evaluated against invasive FFR, when performed. Follow-up for nonfatal myocardial infarction and all-cause mortality was undertaken. The cost of an FFR-CT strategy was compared to alternative stress imaging pathways using cost analysis modeling. ResultsA total of 2,298 CCTAs from 12 centers underwent FFR-CT analysis. Stable chest pain was the main symptom in 77%, and 40% had equivocal stenosis. Positive and negative predictive values of FFR-CT were 49% and 76%, respectively. A total of 46 events (2%) occurred over a mean follow-up period of 17 months; FFR-CT (cutoff: 0.80) was not predictive. The FFR-CT strategy costs £2,102 per patient compared with an average of £1,411 for stress imaging. ConclusionsIn clinical practice, the National Institute for Health and Care Excellence criteria for using FFR-CT were met in three-fourths of patients for symptoms and 40% for stenosis. FFR-CT had a low positive predictive value, making its use potentially more expensive than conventional stress imaging strategies.

Pilot Study for the Assessment of the Best Radiomic Features for Bosniak Cyst Classification Using Phantom and Radiologist Inter-Observer Selection

Since the Bosniak cysts classification is highly reader-dependent, automated tools based on radiomics could help in the diagnosis of the lesion. This study is an initial step in the search for radiomic features that may be good classifiers of benign-malignant Bosniak cysts in machine learning models. A CCR phantom was used through five CT scanners. Registration was performed with ARIA software, while Quibim Precision was used for feature extraction. R software was used for the statistical analysis. Robust radiomic features based on repeatability and reproducibility criteria were chosen. Excellent correlation criteria between different radiologists during lesion segmentation were imposed. With the selected features, their classification ability in benignity-malignity terms was assessed. From the phantom study, 25.3% of the features were robust. For the study of inter-observer correlation (ICC) in the segmentation of cystic masses, 82 subjects were prospectively selected, finding 48.4% of the features as excellent regarding concordance. Comparing both datasets, 12 features were established as repeatable, reproducible, and useful for the classification of Bosniak cysts and could serve as initial candidates for the elaboration of a classification model. With those features, the Linear Discriminant Analysis model classified the Bosniak cysts in terms of benignity or malignancy with 88.2% accuracy.
