Published: February 2022

Countries in various parts of the world make economic growth the initial goal of achieving a country, one indicator used to view economic growth and one of which is the increase in Gross Domestic Product. GDP is the total value of the production of goods or services in a country for one year. This study aims to see what are the factors that influence the economic growth of the superpowers with exports, inflation, and exchange rates, and unemployment as the independent variable and GDP as the dependent variable. This research uses secondary data in the form of a combination of cross-sectional data and time series (panel data). The analytical method used is a panel data regression with a flat model model, covering six countries, namely America, China, India, Korea, Japan, and Thailand during the period 1991-2019. The results show that the Export variable, Exchange Rate, has a significant effect on GDP. Meanwhile, two independent variables, namely inflation, unemployment, did not have a significant effect on the dependent variable.

Published: February 2022

Background: Diabetic retinopathy (DR) is one of the ocular complications among patients with type 2 diabetes (T2D) in both developed and developing countries. At present, epidemiological data of DR and the risk factors among patients with T2D especially in Thai community hospitals have been limited.
Methods: A retrospective cohort study was conducted between January 1, 2013 and December 31, 2020 to determine the incidence and risk factors of DR among patients with T2D visiting Tha Wung Hospital, Lop Buri Province, central Thailand. DR was determined according to the International Classification of Diseases, Tenth Revision codes in E113 presented in medical records. Multivariate Cox regression analysis was performed to obtain the adjusted hazard ratios (HR) and 95% confidence interval (CI) of the factors related to DR.
Results: A total of 2007 patients with T2D were enrolled in the present study. During the study period, participants (5.3%) had a diagnosis of DR; the incidence rate was 0.9 per 100 person-years (95% CI; 0.7-1.1). The independent risk factors for DR included HbA1c ≥8% (adjusted hazard ratio (AHR) = 4.7, 95% CI; 2.5-8.7), urine albumin 3+ (AHR = 2.4, 95% CI; 1.1-5.3), urine albumin 4+ (AHR = 20.3, 95% CI; 2.7-150.9), and a longer distance between residential area (AHR= 1.3, 95% CI; 1.2-1.4).
Conclusion: Patients with T2D should be encouraged to reach their glycemic control indicated by HbA1c level. Additionally, effective health interventions should be conducted to contribute appropriate access to diabetic care for patients residing in remote areas.
The Effect of Planning on Accuracy in Verbal Agreement in L2 Oral Performance
Authors: Qi Hongbo 
Published: February 2022

Accuracy is widely recognized as one of the main dimensions in evaluating task-based oral performance. Indicators of accuracy vary in the literature of the effects of pre-task planning on the oral production. Enlightened by previous studies in pre-task planning and third-person singular -s, this article intends to find out whether the rate of suppliance of thematic verbal agreement increases as a result of pre-task planning, and whether the rate of suppliance of thematic verbal agreement in third-person singular -s increases as a result of pre-task planning. A case study is carried on one subject who makes oral descriptions of a same graph which shows the number of people at London underground station from 6:00 to 22:00 on two separate occasions. The results of this study show that pre-task planning may have significant effect on accuracy of L2 oral output in thematic verbal agreement as a whole, but it may not affect L2 learners in their use of third-person singular -s.

Authors: Güneç Hüseyin Gürkan , Keskin Neslihan Büşra , Haznedaroğlu Faruk 
Published: February 2022

Aim: The aim of this study was to compare the cyclic fatigue resistance of different heat-treated nickel-titanium rotary systems at intracanal temperature.
Methodology: A total of 90 OneCurve (Micro-Mega, Besançon, France), VDW.ROTATE (VDW Dental, Munich, Germany), Typhoon (Clinician’s Choice, New Milford, CT, USA), HyFlex EDM (Coltene/Whaledent AG, Altstatten, Switzerland), and EndoArt Gold and Blue (Inci Dental, Istanbul, Turkey) (n = 15) rotary files (#25/0.06) were tested at intracanal temperature (35.5 ℃) using a dynamic model in a stainless-steel artificial canal with an inner diameter of 1.5 mm, 60° angle of curvature, and 2 mm radius of curvature. Testing was conducted until fracturing, at which time the device stopped automatically, and the number of rotations was calculated as seconds. Lengths of fractured parts were measured using a digital caliper. One-way ANOVA test followed by Tukey’s test was used to compare the groups. Scanning electron microscopic evaluation was performed to confirm the types of fracture.
Results: EndoArt Blue group had a significantly higher mean time to fracture in all groups, followed by the HyFlex EDM, VDW.ROTATE, OneCurve, EndoArt Gold, and Typhoon. In addition, the HyFlex EDM and VDW.ROTATE groups had no significant differences between each other and were significantly better than the others. No significant differences were found between the OneCurve, EndoArt Gold, and Typhoon groups (p>0.05).
Conclusion: This is the first study in the literature for EndoArt NiTi files and the second study for VDW.ROTATE that evaluated cyclic fatigue resistance. Novel EndoArt Blue files exhibited significantly greater cyclic fatigue resistance than the other NiTi files.

The evaluation of panoramic, periapical, and cephalometric radiographic errors in dentistry
Authors: Titiz Serap , Evirgen Şehrazat 
Published: February 2022

Aim: The aim of this study is to determine the effects of working days and hours on panoramic and periapical radiographic errors and investigate the association between patient-induced cephalometric radiographic errors and skeletal malocclusions.
Methodology: Obtained from archives of Manisa Dental Health Center, 1402 periapical, 1329 panoramic, and 309 cephalometric radiographs were investigated retrospectively between January-June 2018, and the radiographic errors were determined. Periapical, panoramic, and total errors were grouped according to the number of radiographs, day intensity, and acquisition date and time for each day. Cephalometric radiographs were not included to determine the effects of working hours and days on radiographic errors since the radiographs were taken over the weekend. Patient-induced cephalometric radiographic errors were investigated under the classification of skeletal malocclusions. The independent sample t-test was used to investigate the average range difference between two independent groups for normally distributed variables. However, in situations where the assumption of normality was not met, the Mann-Whitney U test was performed.
Results: Total errors were mostly detected on Tuesday (p=0.035). Errors of panoramic and periapical radiographs acquired in the afternoon were higher than those of the radiographs acquired before noon only on Monday (p=0.024, p=0.035). The most common errors observed in periapical radiographs were the positioning errors (23.9%) and cone cut (17.3%), respectively. The most common errors observed in panoramic radiographs were chin tipped high (17.00%), and head turned to one side (9.9%), respectively. Among Class I, II, and III malocclusions, open lips were observed as the most frequent cephalometric radiographic errors (28.6, 15.4, and 16.1%, respectively).
Conclusion: The percentage of radiographic errors increases with the intense workload. An anatomical structure may lead to patient-induced cephalometric radiographic errors.

Realizácia outdoorovej edukácie vo vybraných krajinách zapojených do Outward Bound International
Authors: Kancír Ján , Šolcová Sofia 
Published: February 2022

V edukačnom prostredí väčšiny vyspelých krajín sa v ostatných dekádach čoraz intenzívnejšie uplatňuje koncepcia outdoorovej edukácie. Pobyt vo vonkajšom prostredí je jednou z dôležitých podmienok zdravého rozvoja dieťaťa. Má veľký význam pre jeho telesný, kognitívny, sociálny, emocionálny vývin a taktiež prispieva k rozvoju jeho kľúčových kompetencií. Outdoorové aktivity majú nezastupiteľnú úlohu vo výchove a vzdelávaní dieťaťa. Pomáhajú mu porozumieť okolitému svetu, ktorý je reálnym priestorom jeho súčasnej i budúcej existencie. Z tohto hľadiska outdoorové vzdelávanie disponuje edukačným potenciálom, ktorý je nenahraditeľný pri optimalizácii komplexného rozvoja osobnosti žiaka. Cieľom predkladanej štúdie je poukázať na osobitosti outdoorovej edukácie, historický kontext, súčasnosť a budúcnosť jej uplatnenia v edukačnej praxi u nás i v zahraničí. V prvej časti sa venujeme filozofickým východiskám, teórii a praxi experienciálneho učenia. Nasleduje analytická komparácia realizácie outdoorovej edukácie vo vybraných krajinách. Tieto krajiny sú súčasťou svetovo etablovanej organizácie Outward Bound International zameranej (práve?) na outdoorovú edukáciu. Komparácia je spracovaná na báze analýzy informačných zdrojov z plno-textových databáz Proquest, Scopus, Web of science a ďalších. Boli využité literárne metódy, analýza pedagogických dokumentov a literárnych zdrojov našej i zahraničnej proveniencie. V závere ponúkame stručné zhrnutie predmetnej problematiky v podobe prehľadnej tabuľky. Súčasťou štúdie sú aj návrhy na uplatnenie pozitívnych zmien v edukačnej praxi na Slovensku.
Evolución de la igualdad desde la Constitución de 1978: del patriarcado fuerte hacia la igualdad de género
Authors: Lousada Arochena José Fernando 
Published: February 2022

The study analyzes the evolution of the Spanish legal system in matters of equality between women and men since the 1978 Constitution. For this purpose, the different theoretical models of legal systems are made explicit in order to treat equality of women and men: strong patriarchy, which corresponds to a sexist right; moderate patriarchy, which corresponds to a male right built on comparative-based equality laws (classical equality laws); and gender equality, built on equality laws based on overcoming prejudices associated with sex (modern equality laws). On this conceptual taxonomy, in Spain it is verified that the Constitution of 1978 allowed the overcoming of the strong patriarchy, progressively evolving towards gender equality, not yet achieved, but tended to be sought thanks to the transversal equality laws issued in this 21st century.
El estudio analiza la evolución del ordenamiento jurídico español en materia de igualdad de mujeres y hombres desde la Constitución de 1978. A estos efectos, se explicitan, con carácter previo, los distintos modelos teóricos de ordenamientos jurídicos en orden al tratamiento dado a la igualdad de mujeres y hombres: patriarcado fuerte, que se corresponde con un derecho machista; patriarcado moderado, que se corresponde con un derecho masculino construido sobre leyes de igualdad basadas en la comparativa (leyes de igualdad clásicas); e igualdad de género, construida sobre leyes de igualdad basadas en la superación de los prejuicios asociados al sexo (leyes de igualdad modernas). Sobre esta taxonomía conceptual, en España se comprueba que la Constitución de 1978 permitió la superación del patriarcado fuerte, evolucionando progresivamente hacia la igualdad de género, todavía no conseguida, pero tendencialmente buscada gracias a las leyes de igualdad transversales dictadas en este Siglo XXI.

Published: February 2022

This study mainly focused on impact of MIS on prices realization of selected minor forest produce (MFP) viz., honey (Apis dorsata), hill broom (Thysanolaena maxima), Naramamidi bark (Litsea deccanensis), Seeded Tamarind (Tamarindus indica), Marking nut (Semecarpus anacardium) and Myrobalan (Terminalia chebula). Propensity Score Matching (PSM) technique was employed to analyse impact of market information on price realization of MFP. Primary data was collected from 360 farmer respondents from HAT zone in Andhra Pradesh state. The Probit regression results indicated that considered variables has positive significant association and influenced to access market information in the study viz., experience, frequency of visit to Girijan Primary Co-operative Marketing Society (GPCMS), access to mobile phone, education and trainings on the importance of MIS in accessing market information from GPCMS and Primary Procurement Centres (PPCs). Access to market information by the tribal farmers revealed significant impact (P<0.001) on treated, as the impact indicator (prices) is higher for them compared to untreated. The treated were significantly benefited from market information by 15.19 per cent for honey, 37.95 per cent for hill broom and 89.16 per cent for Naramamidi bark, 60.27 per cent for seeded tamarind, 115.45 per cent for Marking nut and 133.34 per cent for myrobalan.
BCG Correlation with Latent Tuberculosis Can Lead to Spurious Correlation with Reduced COVID-19 Mortality
Authors: Raham Tareef Fadhil 
Published: February 2022

Background: Many factors have been suggested to confound coronavirus disease 2019 (COVID-19) studies, and BCG studies have been criticized for not adjusting for many confounders. We conducted this study to analyze the presumed effectiveness of the Bacillus Calmette–Guérin (BCG) vaccine in decreasing the COVID-19 mortality rate, and to answer the question of whether this is confounded by latent tuberculosis (LTB) prevalence.
Materials and Methods: We chose sixty-nine malaria-free countries with different BCG vaccination policies. TB prevalence was considered as a proxy for LTB. The BCG, TB prevalence, and COVID-19 mortality data are publically available. Contingency coefficients (C.C.) and a Receiver Operating Characteristic (ROC) analysis were used to assess the relationship between TB prevalence and BCG status, and identify cutoff points in each BCG group category. A stem–leaf plot was also used to explore the data’s apparent behavior concerning COVID-19 in relation to the BCG groups.
Results: TB prevalence was significantly associated with BCG status. There was a highly significant association according to (C.C.) between TB prevalence and BCG group categories. Countries not implementing BCG vaccinations had low TB prevalence, and vice versa (p value = 0.000). ROC analyses indicating that BCG group is significantly associated with corresponding TB prevalence.
Conclusions: BCG country status has a highly significant relationship with TB prevalence. This can confound BCG and COVID-19 mortality and morbidity studies. In the absence of a correlation ,this can lead to a spurious correlation between BCG and reduced COVID-19 mortality or morbidity.

AbstractObjectiveWhile the anticipated rise of disease‐modifying therapies calls for reliable trial outcome parameters, fluid biomarkers are lacking in spastic paraplegia type 4 (SPG4), the most prevalent form of hereditary spastic paraplegia. We therefore investigated serum neurofilament light chain (sNfL) as a potential therapy response, diagnostic, monitoring, and prognostic biomarker in SPG4.Methods: We assessed sNfL levels in 93 patients with SPG4 and 60 healthy controls. The longitudinal study of sNfL levels in SPG4 patients covered a baseline, 1‐year follow‐up and 2‐year follow‐up visit.ResultsLevels of sNfL were significantly increased in patients with genetically confirmed SPG4 compared to healthy controls matched in age and sex (p = 0.013, r = 0.2). Our cross‐sectional analysis revealed a greater difference in sNfL levels between patients and controls in younger ages with decreasing fold change of patient sNfL elevation at older ages. Over our observational period of 2 years, sNfL levels remained stable in SPG4 patients. Disease severity and progression did not correlate with sNfL levels.Interpretation: Our longitudinal data indicate a stable turnover of sNfL in manifest SPG4; therefore, sNfL levels are not suitable to monitor disease progression in SPG4. However, sNfL may be valuable as a therapy response biomarker, since its turnover could be modified by interventions. As the course of sNfL levels appears to be most dynamic around the onset of SPG4, the ability to detect a therapy response appears to be especially promising in younger patients, matching the need to initiate treatment in early disease stages.
Adaptive output feedback control for large‐scale time‐delay systems with output‐dependent uncertain growth rate
Authors: Jia Xianglei , Xu Shengyuan , Shi Xiaocheng , Lu Junwei , Du Baozhu 
Published: February 2022

SummaryIn this work, the problem of adaptive state regulation is addressed via output feedback for a wide class of large‐scale systems with strongly interconnected time‐delay nonlinearities. A design approach of partially decentralized adaptive controller is proposed, which gives a novel pair of reduced‐order observer and controller with nonidentifier‐based double adaptive gains. Compared with the existing results, the growth restrictions imposed on the interconnections are relaxed, where the growth rate includes not only an unknown constant but also the nonpolynomial functions of system output. The double dynamic gains are capable of compensating both the uncertain nonpolynomial growth rate and the unknown time‐varying delay. By constructing novel Lyapunov–Krasovskii functionals and combining dynamic‐scaling technique with 's lemma, it is shown that global adaptive state asymptotical regulation is achieved, that is all the closed‐loop signals are bounded, and the states of system and observer tend to zero as time goes to infinity. Finally, a simulation example is given to illustrate the proposed control scheme is independent of time delay and well universal.
