Reading skill is an important skill in the mastery of a language as the more the students read, the more exposed they are to the target language. Giving reading comprehension questions that suit the students’ thinking level has been widely known to foster the students’ critical thinking and reading comprehension. This study aimed (1) to explore the cognitive level of the reading comprehension questions found in EFL textbook based on the Revised Bloom’s Taxonomy and (2) to explore appropriate reading comprehension questions to supplement the EFL textbook to meet the Curriculum of 2013. This study analyzed an EFL textbook for year X of high school based on the cognitive domain of the Revised Bloom’s Taxonomy. The findings show that the proportion between LOTS and HOTS questions was 85.5% and 15.5%. Considering that the EFL textbook was dominated by LOTS questions, it was concluded that the EFL textbook was not appropriate for 10th grade students. Therefore, this study proposed 84 appropriate reading comprehension questions to supplement the EFL textbook so as to allow the students to hone their reading skill through various cognitive processes. There was an increase of 20.4% in the percentage of HOTS questions after the addition of the researcher’s supplementary questions, so the proportion between LOTS and HOTS questions became 65.1% (LOTS questions) and 34.9% (HOTS questions).

Published: August 2023

This developmental research aims at developing Higher-Order Thinking Skills (HOTS) reading comprehension questions for senior high school students. This is in line with the national educational goal which is to increase the national competitiveness in the global era while manipulating Higher-Oder Thinking Skills (HOTS) in the global communication. This research is supported by the theory that HOTS questions enable students to think critically. The ADDIE model of instructional design is applied in the process of creating the HOTS reading comprehension questions. Two authentic analytical exposition texts and two authentic explanation texts are used as the reading materials. Twenty five multiple-choice questions of the Analyzing, Evaluating, and Creating levels of the cognitive domain of the Revised Bloom’s Taxonomy (RBT) are developed. A blue print is used as the basis for the questions development to ensure the content validity of the questions. Fifteen students did the test and their answers were scored by the writers. K-R21 was applied to examine the reliability coefficient resulted in r=0.68. This is considered as a high reliability. It is expected that this paper would give beneficial insights for teachers and reading material developers that providing HOTS questions are important for students as reading exercises or tests and that a multiple-choice type of questions can be used. Hence, it is also recommended that other studies be conducted in the use of other types of questions at the level of HOTS to provide more variations of reading programs for students

Published: August 2023

This paper reports on a study which aims at describing the levels of teaching proficiency among the ECCE (Early Childhood Center Education) teachers based on their essential teaching skills in preparing lesson plans, carrying out teaching and learning activities, and assessing learning. This study involved ECCE teachers having a linear educational background (i.e., a bachelor’s degree in early childhood education) and those having a non-linear educational background (i.e., a non a bachelor’s degree in early childhood education). This study is descriptive quantitative in nature employing a survey design. There were 170 ECCE teachers in Sawahan, Nganjuk, East Java participated in this study. Of these participants, 120 had a linear educational background and 50 had a non-linear educational background. The research data were collected using a questionnaire with 30 questions. The results of the study showed that among the teachers involved in the study, 85.88% could be said to be very proficient, 2.94% could be said to be proficient, 8.82% teachers could be said to be less proficient and 2.36% of the teachers could be said to be not proficient. There is no difference in the levels of teaching proficiency between teachers who have linear and non-linear educational background because teachers who do not have linear educational background have got competency enrichment opportunities through teacher trainings, seminars, sharing knowledges with colleagues, and practices in ECCE teacher organizations

Juvenile black sea bass Centropristis striata populations are increasing in southern New England estuaries of the northeastern USA with possible trophodynamic effects on labrid species: tautog Tautoga onitis and cunner Tautogolabrus adspersus. In this study, we examined the abundance, size-structure, and feeding ecology of juvenile sea bass and labrids in Narragansett Bay (Rhode Island, USA) from June to October in 2018 and 2019 and evaluated potential interspecific competition using habitat, diet, and isotopic niche overlap indices. Juveniles (age-0+) of each fish species spatiotemporally co-occurred in shallow, polyhaline habitats throughout the estuary. Age-0 cohorts were numerically dominant across species and initially recruited to the study area in July (minimum total length, TL = 15-20 mm), reached peak abundances in mid- to late summer (maximum abundances = 12-140 fish 100 m-2), and emigrated from field sites in October (maximum TL = 85-96 mm). Stomach content and stable isotope (δ15N and δ13C) analyses determined that focal fishes were generalist carnivores that foraged in bentho-pelagic food webs. Fishes also overlapped in their respective ambit and core isotopic niche space, but interspecific dietary overlap was size-dependent. Dietary overlap was most pronounced between sea bass ≤49 mm TL and labrids ≤59 mm TL due to their mutual reliance on gammarid and caprellid amphipods. Ontogenetic dietary shifts then resulted in food niche segregation, such that sea bass 50-139 mm TL consumed decapod crustaceans and fish, whereas labrids 60-181 mm TL mainly fed on amphipods, worms, bivalves, and turf-associated biota, i.e. bryozoans, hydroids, and seaweeds. Habitat and trophic niche overlap between early juvenile sea bass and labrids purportedly have not caused opposite population trajectories or food resource limitation in Narragansett Bay, indicating an absence of exploitative competition. Alternatively, realized competition between species may be too spatiotemporally restricted to alter their population dynamics. Continuous monitoring of the sea bass’s bio-ecological effects in southern New England estuaries is warranted, however, given their recent range expansion and increasing abundances at northern latitudes.

El presente artículo evalúo la influencia de la Interacción Suelo – Estructura (ISE) en la respuesta estructural lineal de sistemas muro-pórtico regulares representativos de Bucaramanga-Colombia utilizando el enfoque de subestructura propuesto por Winkler. Se recopiló información de sistemas locales existentes utilizando base de datos oficiales. Mediante el diseño de experimentos factorial 22, se crearon nueve edificios artificiales con diferentes tipos de suelo y número de pisos. Estos edificios fueron diseñados y detallados bajo la idealización de base fija, siguiendo la normativa sismorresistente local. Se llevaron a cabo análisis incluyendo y excluyendo la ISE. Los resultados revelaron que la ISE tuvo influencia significativa en la respuesta lineal de las estructuras ubicadas en zonas de amenaza sísmica alta, presentando variación en el periodo fundamental, cambio en la respuesta modal, incremento de derivas y disminución en el cortante de base. Además, se encontró que también afecta el método de análisis utilizado para el diseño.
This paper evaluates the influence of Soil-Structure Interaction (SSI) on the linear structural response of regular wall-frame systems representative of Bucaramanga-Colombia using the substructure approach proposed by Winkler. Information was collected from existing local systems study using official databases. Using the 22 factorial design of experiments, nine artificial buildings were created with different soil types and number of floors. These buildings were designed and detailed under the fixed base idealization, following the local seismic-resistant regulations. Analyses were carried out including and excluding the ISE. The results revealed that the ISE had a significant influence on the linear response of structures located a high seismic hazard zone, presenting variation in the fundamental period, change in the modal response, increase in drifts and decrease in the base shear. In addition, it was found that it also affects the analysis method for the design.

Authors: Pellegrini Jorge , De Celis Jorge
Published: August 2023

El presente trabajo estudia el ajuste de los datos experimentales de las isotermas de adsorción en un sistema de cromo hexavalente como adsorbato y carbón activado como adsorbente. Los ensayos de adsorción consistieron en poner en contacto 0,1 gramo de adsorbente con soluciones de diferente concentración de cromo hexavalente durante 48 h a distintas temperaturas. Para el modelado se propuso un método distinto al tradicional, mediante el cual se optimiza la energía de activación de la adsorción de manera que se generen las contantes de equilibrio que minimicen el error cuadrático medio respecto a los datos experimentales. Para ello, se empleó Simulated Annealing como algoritmo de optimización. Una temperatura inicial de 1000, 10000 iteraciones y un tamaño de paso de 0,05 fueron los parámetros utilizados. Ambos métodos presentan ajustes adecuados, mostrando energías de activación del mismo orden. Esto indicaría que el algoritmo de optimización sería comparable a los procedimientos tradicionales. 
 
The present work studies the adjustment of the experimental data of the adsorption isotherms in a system of hexavalent chromium as adsorbate and activated carbon as adsorbent. The adsorption tests consisted of using 0.1 gram of adsorbent with solutions of different concentrations of hexavalent chromium for 48 h at different temperatures. For the modeling, a method different from the traditional one was proposed, where the adsorption activation energy is optimized to generate the equilibrium constants that minimize the mean square error with respect to the experimental data. For this, Simulated Annealing was used as the optimization algorithm. An initial temperature of 1,000, 10,000 iterations, and a step size of 0.05 were the parameters used. Both methods present adequate adjustments, showing activation energies of the same order. This would indicate that the optimization algorithm would be comparable to traditional procedures.

This is motivated by the low learning outcomes of students on the material price index and inflation. This is due to a lack of understanding of the material and the limitations of the learning media used for the learning delivery process. So this development research aims to find out how Android-based interactive media can improve student learning outcomes. This R&D research uses the thiagarajan model known as 4D namely Define, Design, Develop, and Disseminate. The subjects of this research were students of class XI IPS 2 at SMAN 15 Surabaya, which consisted of 34 students. Android-based interactive media obtained a material validity feasibility value of 97% and media experts 95%, namely with a very feasible interpretation. Meanwhile, the students' responses obtained a score of 96% with a very proper interpretation. In measuring the increase in learning outcomes carried out by the N-Gain test which obtained a result of 0.69 which is included in the medium category. Therefore it can be seen that there is an increase in student learning outcomes. This increase occurred because the presentation of media designs that were developed was attractive and fun, supplemented by animated video illustrations of material, supplemented by learning evaluations with multilevel methods, ease of operation and flexible use of media, and media designed interactively to increase student motivation in obtaining better learning outcomes. better. So the conclusion that is obtained is that Android-based interactive media is recommended for use in the learning process and is able to improve student learning outcomes.

The purpose of this study was to standardize the National Institute of Special Education- Korean·Autism Rating Scale for Teachers(NISE-K·ART). The NISE-K·ART assess two domains: social communication and social interaction(SC) and the restricted repetitive behaviors, interests, and activities(RRB). The scale was developed for preschoolers (3-5 years old), elementary school students (6-12 years old), and middle and high school student (13-18 years old) and is capable of assessing different grade levels. The NISE-K·ART was administered to 561 students with ASD for standardization and to 318 students with intellectual disabilities and 319 students without disabilities for assessing clinical utility. For item analysis, item difficulty and discrimination were analyzed based on item response theory. For validity, construct validity, quasi-validity, and discriminant validity were examined; and for reliability, internal consistency (Cronbach’s α), test-retest reliability, and inter-rater agreement were tested. The study revealed the following. First, after we examined the difficulty and discrimination of the NISE-K·ART, we found that the scale consisted of items of varying difficulty (severity) and had fair discrimination. Second, the reliability analysis showed that the NISE-K·ART had high internal consistency, test-retest reliability, and inter-rater agreement. Lastly, the study confirmed that the NISE-K·ART had high validity and high discrimination between groups. Based on these findings, we discuss the significance of the NISE-K·ART and how to utilize it.

In 2022 and at the beginning of 2023, the financial system of Ukraine proved its institutional capacity. The results of the banks' activities in 2022 confirm their significant contribution to its stabilization during the period of full-scale Russian aggression. The measures of the monetary authority were more balanced and effective compared to the events of 2014-2015. The current state of the banking system proved the integration of Ukrainian banks into the European financial space. Problem Statement. Systematization of problems and approaches to the strategic development of the banking system in the period of post-war economic recovery and its impact on the general security of money circulation in the country.The given calculations and graphs make it possible to compare the trends in the main markets of banking operations in 2014–2023. Purpose. To assess the current state of dynamics of active and passive operations of Ukrainian banks after the pandemic crisis and in the midst of full-scale Russian aggression, as well as the impact of their activities on the development of the real sector. Methods. General scientific and special methods are used: analysis, synthesis, grouping, description, comparison, theoretical generalization and abstract-logical. Results. The dynamics of changes in the resource base of banks at the expense of legal entities and individuals, as well as their credit and investment portfolios, are presented. The main macroeconomic strategies of monetary policy, which influenced the development of banks in 2014–2023, were considered. The importance of resuming the cooperation of the Government of Ukraine with international financial organizations in 2023 and further institutional development of the banking system was emphasized. Conclusions. The quality of management of the financial sector and the banking segment, in particular in 2022, is higher than in 2014. The bank-centric financial system that has developed in Ukraine should have a long-term strategy for the development of institutions along with a transparent mechanism for evaluating the quality of their management. For the development of the banking system in order to improve the resource provision of the economy, it is necessary to return to the idea of creating a national reconstruction and development bank, a bank of assets damaged and destroyed by the war.
Effect of Digitalization on Nursing Practices using the Lean Approach
Authors: UZUN Lütfiye Nur , CERİT Birgül
Published: August 2023

Objective: This study aimed to examine the effect of digitalization on nursing practices using the lean approach.

Method: This is a descriptive observational study. The data were collected using an activity chart to record nurses’ direct and indirect care practices and personal work and the Value Stream Map to compare and analyze work processes and determine both waste and value areas in the clinics. The study included a total of 15 nurses from two different internal medicine units of a hospital, including one digital clinic that uses digital applications for nurse work processes, and one partial digital clinic that has limited digital applications. The data were analyzed using current state value stream mapping, lean seven waste areas, and future state value stream mapping.

Results: In the digital clinic, 748.5 minutes were allocated for direct care, 129.1 minutes for indirect care, and 562.1 minutes for personal work. Total value-added time and non-value-added time was calculated as 1137.1 and 302.9 minutes, respectively. In the partial digital clinic, 623.9 minutes were allocated for direct care, 404.4 minutes for indirect care, and 411.1 minutes for personal work. Total value-added time and non-value-added time was calculated as 1006 and 433.4 minutes, respectively. According to the future state value stream map prepared in line with the improvement suggestions to eliminate unnecessary production, process, movement, transportation, waiting, and error waste in the current state of both clinics, it is predicted that 1354.3 minutes of value-added time will be obtained and non-value-added time will decrease to 85.7 minutes, by spending 910.9 minutes less on direct care, 190.2 minutes less on indirect care, and 259.2 minutes less on personal work.

Conclusion: The lean approach creates a repeated opportunity to review and improve processes. Analyzing nursing processes using the lean approach before and after digitalization and reviewing sources of both waste and value will contribute to implementing higher quality nursing care practices more effectively and safely and to using time and staff more efficiently.

Published: August 2023

This paper initially employs the gravity model in order to analyze the trade data of selected 23 OIC countries and its 4 different subgroups. Then it applies stochastic frontier analysis to the model to gain efficiency scores and uncapped trade potential among countries in order to determine whether the group would have trade creation effect once they go for a Common Market structure. According to the statistical results, the 23 country group gives statistically significant results while deriving a %62 uncapped trade potential among group countries. Additionally, the 13-country subgroup also gives statistically significant results while deriving a %59 uncapped trade potential among them.

While there are a number of studies which applies stochastic frontier analysis to the gravity model and gains efficiency scores, this study is the first to employ the method for OIC countries in order to determine the best possible country group for a Common Market without having trade diversion affect. The purpose of this study is to determine the Common Market options for Turkiye in the scope OIC in order to be a reference point for future Common Market initiatives.

Authors: Tang Chao , Lei Fenfang , Liu Jirong , Gong Fengxiang
Published: August 2023

The infection rate in the Neonatal Intensive Care Unit (NICU) is very high, which is also one of the important causes of morbidity and even death in critically ill neonates and premature infants. At present, the monitoring system of the Neonatal Intensive Care Unit is not very complete, and it is difficult to provide early warning of neonatal illness. Coupled with the untimely response measures, it has brought certain difficulties to the ward’s infection prevention and control work. The rapid development of the Internet of Things (IoT) in recent years has made the application fields of various sensor devices more and more extensive. This paper studied infection prevention and early warning in the Neonatal Intensive Care Unit based on physiological sensors. Combined with a wireless network and physiological sensors, this paper built an intelligent monitoring system for the Neonatal Intensive Care Unit, which aimed to monitor various physiological data of newborns in real-time and dynamically, and gave early warning signals, so that medical staff could take preventive measures in time. The experiments showed that the monitoring system proposed in this paper could obtain the physiological information of neonates in time, which brought convenience to prevention and early warning work, and reduced the infection rate of neonatal wards by 7.39%.

Bone regeneration is a dynamic process that involves angiogenesis and the balance of osteogenesis and osteoclastogenesis. In bone tissue engineering, the transplantation of mesenchymal stem cells (MSCs) is a promising approach to restore bone homeostasis. MSCs, particularly their small extracellular vesicles (sEVs), exert therapeutic effects due to their paracrine capability. Increasing evidence indicates that microRNAs (miRNAs) delivered by sEVs from MSCs (MSCs-sEVs) can alter gene expression in recipient cells and enhance bone regeneration. As an ideal delivery vehicle of miRNAs, MSCs-sEVs combine the high bioavailability and stability of sEVs with osteogenic ability of miRNAs, which can effectively overcome the challenge of low delivery efficiency in miRNA therapy. In this review, we focus on the recent advancements in the use of miRNAs delivered by MSCs-sEVs for bone regeneration and disorders. Additionally, we summarize the changes in miRNA expression in osteogenic-related MSCs-sEVs under different microenvironments.

Type 2 diabetes (T2D) has been rising in prevalence over the past few decades in the US and worldwide. T2D contributes to significant morbidity and premature mortality, primarily due to cardiovascular disease (CVD). Exercise is a major cornerstone of therapy for T2D as a result of its positive effects on glycemic control, blood pressure, weight loss and cardiovascular risk as well as other measures of health. However, studies show that a majority of people with T2D do not exercise regularly. The reasons given as to why exercise goals are not met are varied and include physiological, psychological, social, cultural and environmental barriers to exercise. One potential cause of inactivity in people with T2D is impaired cardiorespiratory fitness, even in the absence of clinically evident complications. The exercise impairment, although present in both sexes, is greater in women than men with T2D. Women with T2D also experience greater perceived exertion with exercise than their counterparts without diabetes. These physiological barriers are in addition to constructed societal barriers including cultural expectations of bearing the burden of childrearing for women and in some cultures, having limited access to exercise because of additional cultural expectations. People at risk for and with diabetes more commonly experience unfavorable social determinants of health (SDOH) than people without diabetes, represented by neighborhood deprivation. Neighborhood deprivation measures lack of resources in an area influencing socioeconomic status including many SDOH such as income, housing conditions, living environment, education and employment. Higher indices of neighborhood deprivation have been associated with increased risk of all-cause, cardiovascular and cancer related mortality. Unfavorable SDOH is also associated with obesity and lower levels of physical activity. Ideally regular physical activity should be incorporated into all communities as part of a productive and healthy lifestyle. One potential solution to improve access to physical activity is designing and building environments with increased walkability, greenspace and safe recreational areas. Other potential solutions include the use of continuous glucose monitors as real-time feedback tools aimed to increase motivation for physical activity, counseling aimed at improving self-efficacy towards exercise and even acquiring a dog to increase walking time. In this narrative review, we aim to examine some traditional and novel barriers to exercise, as well as present evidence on novel interventions or solutions to overcome barriers to increase exercise and physical activity in all people with prediabetes and T2D.

Phytoremediation techniques have been widely used in the treatment of heavy metal contaminated soils in recent years, but there is no effective post-treatment method for plant tissues containing heavy metals after remediation. Elsholtzia Harchowensis is a copper hyperaccumulator, commonly distributed in copper mining areas and often used for soil remediation of mine tailings. Moreover, copper-based catalysts are widely used in electrocatalytic reduction of carbon dioxide, which aims to convert carbon dioxide into useful fuels or chemicals. In this study, copper-modified biochar was prepared from Elsholtzia Harchowensis. Its specific surface area can reach as high as 1202.9 m2/g, with a certain porous structure and even distribution of copper on the amorphous carbon. Various products (such as carbon monoxide, methane, ethanol, and formic acid) could be obtained from the electrolytic reduction of carbon dioxide by using the as-prepared catalyst. Instantaneous current density of up to 15.3 mA/cm2 were achieved in 1.0 M KHCO3 solution at a potential of −0.82 V (vs. RHE). Electrolysis at a potential of −0.32 V (vs. RHE) for 8 h resulted in a stable current of about 0.25 mA/cm2, and the Faraday efficiency (FE) of carbon monoxide can reach as high as 74.6%. In addition, electrolysis at a potential of −0.52 V (vs. RHE) for 8 h led to a stable current of about 2.2 mA/cm2 and a FE of 8.7% for the C2 product. The rich variety of elements in plants leads to catalysts with complex structural and elemental characteristics as well, which facilitates the electrolytic reduction of carbon dioxide with a variety of useful products.

Wide bandgap oxidized graphenes have garnered particular interest among the materials explored for these applications because of their exceptional semiconducting and optical properties. This study aims to investigate the tunability of the related properties in reduced graphene oxide (rGO) for potential use in energy conversion, storage, and optoelectronic devices. To accomplish this, we scrutinized crucial parameters of the synthesis process such as reduction time and temperature. Our findings demonstrate that controlling these parameters makes it possible to customize the optical bandgap of reduced graphene oxide within a range of roughly 2.2 eV–1.6 eV. Additionally, we observed that reduced graphene oxide has strong and superior absorption in the visible region, which is attributable to the existence of OFGs and defects. Notably, our results indicate that the absorption coefficients of reduced graphene oxide are up to almost three times higher (7426 ml mg−1 m−1) than those observed in dispersions of exfoliated graphene and graphene oxide (GO). To complement our findings, we employed several spectroscopic and morphological characterizations, including scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and electrical measurements. The implications of our results are significant for the development and design of future semiconductors for energy conversion and optoelectronic applications.

Aim

COVID-19 pandemic has spread widely at unpreceded pace. Cardiovascular comorbidities are significantly correlated with severe and critical illness. Nevertheless, studies examining the impact of congenital heart disease on COVID-19 severity are scarce and restricted to hospitalized patients. This study aims to explore the course of COVID-19 illness, severity and complications in patients with concomitant congenital heart disease.

Methodology

This study is a cross sectional survey that includes patients with congenital heart disease who are registered at the Children Heart Center at the American University of Beirut Medical Center. The survey was conducted in the pediatric cardiology outpatient clinics or remotely via phone calls.

Results

A total of 238 patients participated in the study, of which 47.9% had suspected or confirmed diagnosis of SARS-CoV-2 infection. The majority of patients had mild illness. The symptoms ranged between rhinorrhea (15.6%), cough (15.6%), low-grade fever (11.2%), anosmia (2.7%), ageusia (2.5%), headache (9.8%), high-grade fever (8.5%), gastrointestinal symptoms (7.6%), lethargy (6.3%), muscle aches (5.6%), difficulty breathing (5.4%), joint pain (4.7%), and chills (4.7%). 20% of the surveyed patients required treatment at home. Hospitalization and oxygen therapy was required in 3.5% of cases, while only 1.5% demanded intensive care admission. Only one fatality was encountered.

Conclusion

COVID-19 infection in pateints with congenital heart disease exhibits a mild to moderate course, and doesn't necessarily increase risk of complicated disease. No correlation could be found between specific congenital heart lesion and disease severity.
