This study aims to determine the effect of the ability to understand mathematical concepts with anxiety and independence in learning mathematics in Tadris Mathematics students at UIN Fatmawati Sukarno Bengkulu. A good understanding of mathematical concepts is an important aspect of learning mathematics, while anxiety and independent learning can affect performance and learning outcomes in mathematics. The approach used in this study is quantitative where this research uses a correlational research design. The sample used in this study was Tadris Mathematics students at UIN Fatmawati Sukarno Bengkulu Class of 2021 who are taking lectures this semester. The instruments used included testing the understanding of mathematical concepts, the mathematics anxiety questionnaire, and the mathematics learning independence questionnaire. The description of mathematical concepts is one of the key aspects in the success of learning mathematics mathematics. The results of the information analysis show that there is a significant relationship between the description of the concept and anxiety and learning independence. Students who have a better understanding of concepts tend to have lower levels of anxiety and greater levels of learning independence. These findings indicate that conceptual understanding has an important role in reducing anxiety and increasing student learning independence. This research makes a crucial contribution to our understanding of the factors that influence students' learning anxiety and independence in mathematics. The practical implication of this research is that learning approaches that promote effective understanding of concepts can help reduce students' anxiety and increase their learning independence. Therefore, it is important for students in the Tadris Mathematics study program as prospective mathematics teachers to consider understanding concepts as a relevant factor in supporting learning success.

Background Diagnosis-based surveillance of COVID-19 underestimates COVID-19 burden. Questions about COVID-19-consistent symptoms were added to three population-based surveys to obtain representative estimates of COVID-19 period prevalence and monthly cumulative incidence. Objective To evaluate if estimates of COVID-19 period prevalence and cumulative monthly incidence differed when collected from surveys with different sampling frames and modes of administration. Methods Data were collected from adult New York City (NYC) residents via the Community Health Survey (CHS) (sampling frame: random digit dial with dual landline and cellphone frame; mode: phone) and the Citywide Mobility Survey (CMS) (sampling frame: probabilistically selected panel; mode: online) in July 2020 and via CHS and Healthy NYC (sampling frame: probabilistically selected panel; mode: online and phone) in August 2020. Persons with COVID-19-like illness (CLI) were identified based on reported symptoms in the past 30 days. To obtain COVID-19 estimates, CLI estimates were adjusted by the proportion of laboratory-confirmed SARS-CoV-2 infections among citywide emergency department CLI visits in which patients received SARS-CoV-2 testing. We used t-tests to compare estimated CLI period prevalence in July 2020 between CHS and CMS and CLI period prevalence and cumulative monthly incidence in August 2020 between CHS and Healthy NYC. Results CLI period prevalence was similar between CHS and CMS during July (12.2% vs. 9.9%, respectively, p=0.511); COVID-19 period prevalence was 1.7% and 1.3%, respectively. In contrast, CLI period prevalence was higher per Healthy NYC during August 2020 than CHS (18.1% vs. 11.3%, p=0.014); COVID-19 period prevalence was 0.7% and 0.4%, respectively. CLI cumulative monthly incidence in August was similar (5.7% and 4.0%, respectively; p=0.246) in both surveys. Conclusions Because estimates of CLI were not consistently different by sampling frame or mode of administration, additional research to understand the cause of differences between CHS and Healthy NYC can support use of symptom-based surveillance to monitor COVID-19 trends.

Published: September 2023

Slow-release fertilizer (SRF) with chitosan (CS) coating as a supply of plant nutrients is an alternative to the efficient use of conventional chemical fertilizers and reduces environmental pollution. However, its potential in woody plants is limited. This study aimed to analyze the effect of SRF on Falcataria moluccana germination and SRF phosphorus release rate. This study used SRF from polymerizing CS with methacrylic acid (MAA) to trap nutrients (CS-PMAA-nutrients SRF). The seeds of F. moluccana were germinated at six concentrations SRF: without fertilizer (F0), SRF CS dose 0.5% weight 0.03 g (F1), SRF CS 0.5% 0.01 g (F2), SRF CS 0.7% 0.03 g (F3), SRF CS 0.7% 0.01 g (F4), and conventional fertilizer (F5) for 21 days. SRF can increase the germination of F. moluccana. F4 increased normal sprout (10%) and germination power (16%) of F. moluccana. Furthermore, SRF with a concentration of 0.01 g produced a higher germination value than a concentration of 0.03 g. The release rate of SRF’s nutrients was slower (91.80% phosphorus) than conventional fertilizers. SRF application can reduce nutrients lost and increase the efficiency of nutrient absorption. Hence, it can improve F. moluccana growth.

Published: September 2023

Cavernous sinus syndrome is characterized by ophthalmoplegia, diplopia, facial hypoesthesia, Horner syndrome and proptosis. The authors present a clinical case of an 89-year-old woman presented to the emergency department with complaints of vomiting, severe left frontotemporal headache, photophobia, left ptosis and diplopia with less than 24 hours of evolution. Neurological examination revealed ptosis and limitation of all eye movements in the left eye. Cranioencephalic computed tomography and magnetic resonance imaging showed an expansive lesion with expression in the suprasellar cistern and in the left cavernous sinus, suggestive of a macroadenoma with signs of hemorrhagic transformation. Cavernous sinus syndrome has several etiologies, as cerebrovascular diseases, infectious diseases, and trauma. In addition to the clinical history and physical examination, imaging tests are essential to determine the etiology behind this syndrome.

Published: September 2023

Background:
Motor evoked potentials (MEPs) using transcranial magnetic stimulation (TMS) may give a functional assessment of corticospinal conduction. The aim of this study is to confirm the value of MEPs for the assessment of the dysfunction in spinal cord transmission in patients with clinically minimally symptomatic or asymptomatic and acute-subacute odontoid pathologies.
Methods:
We measured the MEPs of five cases with acute-subacute odontoid dislocations by using TMS. Demografic features, neurological examinations and neuroimaging findings of the patients have also been noted.
Results:
The CMCTs and MEP latencies after cortical stimulus of all patients with acute-subacute odontoid dislocation prolonged bilaterally. Additionally, MEP amplitudes were observed decreased in all cases.
Conclusions:
MEP is quite valuable to show involvement in clinically and radiologically silent cases. Our findings in acute-subacute cases without myelopathy showed us that the CMCTs were prolonged especially in the cases who had motor defisits but also in asymptomatic cases.

Emphysema is a chronic lung disease in which the walls of the alveoli in the lungs weaken and collapse; leaving abnormally large residual spaces filled with air even when the patient exhales. The most common symptoms of emphysema are shortness of breath (dyspnea); cough; fatigue; and weight loss. Emphysema often coexists with chronic obstructive pulmonary disease. The treatment of emphysema requires a multidisciplinary approach; including education; exercise; tobacco cessation; oral and inhaled medications; oxygen therapy; and lung transplantation. Lung volume reduction surgery (LVRS) may be an option for patients who experience shortness of breath and whose pulmonary function tests show severe obstruction and enlarged lungs. The surgery aims to remove the least functional part of the lung to improve airflow; diaphragm; and chest wall mechanics; as well as alveolar gas exchange in the remaining lung.
Objective — to familiarize doctors with the clinic’s experience in reducing lung volume in patients with bullous emphysema.
Materials and methods. Our clinic performed the following surgical interventions to reduce lung volume: VATS resection of large (giant) lung bullae — 14 (77.7 %) cases; VATS lo­­bec­tomy — 2 (11.1 %); lobectomy through thoracotomy — 1 (5.6 %); VATS sublobar resection — 1 (5.6 %).
Results and discussion. There were no fatalities. The following postoperative complications were recorded: prolonged under-expansion of the operated lung in 5 (27.7 %) cases; empyema of the residual pleural cavity with bronchial fistula in 1 (5.6 %). The overall incidence of postoperative complications was 33.3 %. Two patients with prolonged underdistension of the operated lung required reoperation (VATS revision of the pleural cavity and redilation). The patient who developed pleural empyema with a bronchial fistula underwent bronchial blockage with a satisfactory result. In all cases of LVRS; a positive clinical effect was recorded in the first 3 months after surgery. During the follow-up period of up to 2 years; only 2 (11.1 %) patients showed no clinical effect and signs of progression of chronic obstructive pulmonary disease and respiratory failure were observed.
Conclusions. Lung volume reduction surgery is a method of treating bullous lung disease that allows achieving overall treatment effectiveness in the follow-up period of up to 3 months in 100 % of cases; and in the follow-up period of up to 2 years — in 89.9 %. The high rate of postoperative complications in LVRS requires a physician to carefully select patients for surgery and monitor their condition daily in the postoperative period.

Purpose: The purpose of this study is to perform a systematic review of the scientific literature to compare single and double row techniques for rotator cuff tears in terms of functional, pain improvement and structural healing of the tendon.

Methods: In order to carry out the research, a systematic selection of scientific articles has been made by consulting PubMed and The Cochrane Library databases. The articles included in the present study compare the single-row and double-row techniques, with publication date between 2016 and 2021.

Results: Diverse results are observed in the UCLA, SST, Constant and ASES assessment scales and in the range of mobility, therefore, the superiority of one technique in terms of functional results is not established. The double row technique may show superiority in the strength variable, although there is a methodological variability in its measurement. The double-row technique may be related to more intense postoperative pain, while the single-row technique to residual shoulder pain. However, the variables strength and pain show non-homogeneous or coincident data. The superiority of the double row repair in the structural healing of the tendon and a lower re-tear rate than the single row technique is established with statistically significant results, being the most homogeneous and coincident studies.

Methods and software for capturing three-dimensional digital images using spatial demodulation
Authors: Borovytsky V. M. , Gudz О. E. 
Published: September 2023

The paper proposes the generalized technique of demodulation, which can be applied for capturing digital three-dimensional images in optical microscopes. This technique allows the calculation of the contrast of harmonic spatial modulation with any values of phase angles. The input data is a stack of digital images with harmonic spatial modulation. Three digital images with different phases of modulation captured in the same focus position are processed to get one data set about the contrast distribution. This data makes it possible to compose the three-dimensional images by the selection of the maximal values of the contrast in three-dimensional space. The paper contains the analytical solution of the system with three linear equations that helps to identify the principal parameters of harmonic spatial modulation, including its average value and contrast. As a result, the expression for contrast calculation is present in an analytical form. This expression is valid for any modulation phase angles that do not coincide. The paper contains MathCAD modeling, which illustrates the procedure of composing the three-dimensional images.
The modeling confirms the correctness of described calculations and demonstrates the built of the three-dimensional surface image as a composition of the contrast distribution map and the corresponded height map. The advantage of the proposed technique is the possibility to apply the economical units for the formation of a harmonious spatial modulation. These units can be installed on most optical microscopes with digital cameras and motorized focusing drives without purchasing expensive commercial software. It significantly reduces the price of transforming these optical microscopes into instruments for capturing digital three-dimensional images.
