Role of Enforcement in Stabilization of Non-Proliferation Regime
Authors: Kalyadin A.
Published: April 2021

The practical use of nuclear weapons displayed the necessity to toughen the responsibility for serious contempt of the international legal non-proliferation norm, to make the NPT regime more "sharp-toothed", to fill vivid gaps in this regime and place a reliable safety screen in the way of nuclear arsenals creation. The author investigates the means and tools of nuclear proliferation interception, and suggests options to produce an essential positive effect by weakening of pressure on the world politics from some countries' powerful forces which make the case for other legitimized coercion sources referring to the "ineffectiveness" of the UN.

Long War against Terror
Authors: Nosenko T.
Published: April 2021

In the article, different reasons for the long-lasting war against international terrorism under the Islamist banner are analysed. Notwithstanding the "Al-Qaeda's" weakening, since autumn 2001, many new groups have sprung up threatening the international security. Till now, the war has been waged only against terrorists, but no serious attention has been paid to neutralization of radical Islamism as an ideology causing terrorism. In connection with the military actions in Iraq and Afghanistan, anti-western feelings have been growing up breeding radical Islamism. It is emphasized in the article that the antiterrorist coalition in its present state is unable to fulfill its mission. It can become really efficient only if Muslim régimes would increase their input into the common struggle. Standing on the ground of traditional Islam they could easier curb Islamism and thus cut the roots of terrorism.
Pricing Theories and Globalization
Authors: Dunayeva E.
Published: April 2021

The article considers the evolution of price-setting theories. Classic conceptions concentrated on processes occurring inside national economies. Since the mid-21st century, the analysis of external factors of pricing has become more significant. It is shown that the available concepts of price-setting cannot adequately explain ups and downs of international prices that were evidenced in the early 21st century.

TEOQUILOMBISMO: TEOLOGIA NEGRA ENTRE TEOLOGIA POLÍTICA E TEOLOGIA DA INCULTURAÇÃO
Authors: Caldeira Cleusa
Published: April 2021

O pensamento negro crítico há tempos vem denunciando o colonialismo como a maior fratura intersubjetiva da história moderna, que se revelou o mais eficaz e durável instrumento de dominação universal. Fratura esta que exigiu a classificação hierárquica da humanidade, isto é, a divisão entre humanos e subumanos, entre dominados e dominadores. Neste mundo maniqueísta, as pessoas de origem africana, suas culturas e suas espiritualidades foram relegadas ao primitivo, inferior e diabólico. A teologia negra surgiu como um protesto radical à essa pulsão genocida da modernidade e defesa da dignidade da vida negra. Entretanto, constata-se que o colonialismo perdura como colonialidade, em sua capacidade ilimitada de atualização. Isso demanda também uma atualização das ferramentas teóricas e conceituais para enfrentar o racismo contemporâneo. Da interlocução da teologia com o pensamento crítico negro surge o Teoquilombismo, uma reflexão teológica para pensar a libertação negra entre teologia negra política e teologia da inculturação.
On Spacetime Duality and Bounce Cosmology of a Dual Universe
Authors: Al-Fadhli Mohammed B.
Published: April 2021

The recent Planck Legacy release confirmed the existence of an enhanced lensing amplitude in the cosmic microwave background (CMB) power spectra, which endorses the positive curvature of the early Universe with a confidence level exceeding 99%. In this study, the pre-existing curvature is incorporated to extend the field equations where the derived wave function of the Universe is utilized to model Universe evolution with reference to the scale factor of the early Universe and its radius of curvature upon the emission of the CMB. The wave function reveals both positive and negative solutions, implying that matter and antimatter of early Universe plasma evolve in opposite directions as distinct Universe sides. The wave function indicates that a nascent hyperbolic expansion is followed by a first phase of decelerating expansion away from early plasma during the first 10 Gyr, and then, a second phase of accelerating expansion in reverse directions, whereby both Universe sides free-fall towards each other under gravitational acceleration. Simulations of the predicted conformal curvature evolution demonstrate the fast orbital speed of outer stars owing to the external fields exerted on galaxies as they travel through conformally curved space-time. Finally, the wave function predicts an eventual time-reversal phase comprising rapid spatial contraction that culminates in a Big Crunch, signalling a cyclic Universe. These findings reveal that early plasma could have separated and evolved into distinct sides that collectively and geometrically influencing the Universe evolution, physically explanting the effects attributed to dark matter and energy.
Time Series Analysis of Geotechnical Data From a Sensor Network Controlling the Remoted Pipeline
Authors: Vladova Alla Yu.
Published: April 2021

Extensive, but remote oil and gas fields of the United States, Canada, and Russia require the construction and operation of extremely long pipelines. Global warming and local heating effects lead to rising soil temperatures and thus a reduction in the sub-grade capacity of the soils; this causes changes in the spatial positions and forms of the pipelines, consequently increasing the number of accidents. Oil operators are compelled to monitor the soil temperature along the routes of the remoted pipelines in order to be able to perform remedial measures in time. They are therefore seeking methods for the analysis of volumetric diagnostic information. To forecast soil temperatures at the different depths we propose compiling a multidimensional dataset, defining descriptive statistics; selecting uncorrelated time series; generating synthetic features; robust scaling temperature series, tuning the additive regression model to forecast soil temperatures.

Published: April 2021

The dramatic increased rates of uncontrolled urbanization in various parts of the World have resulted in loss of native species and overall threats to biodiversity. Over the last few decades Saudi Arabia has witnessed a remarkably rapid population growth and unparalleled levels of urbanization, leading to threats to biodiversity. Ants were pitfall-trapped across an urban-rural gradient to evaluate ant assemblage responses to urbanization in Wadi Hanifa, Riyadh, Central Saudi Arabia. Fifteen sampling sites were selected along three different urbanization gradients, each traversing urban, suburban and rural zones. Within each site 10 traps were distributed and operated for 7 consecutive days, at 3-monthly intervals throughout one year. Vegetation, ground cover, and chemical and physical soil variables at sampling sites were analyzed concurrently. Ant abundance, species richness, evenness, and diversity indices of Shannon and Simpson were calculated for each site using PC-ORD to demonstrate diversity patterns along the urbanization gradients. Ant assemblages were assessed by detrended corresponding analysis (DCA), canonical correspondence analysis (CCA), and analysis of similarity (ANOSIM) using PC-ORD. Indicator species analysis was conducted to define representative species along the urbanization gradient. A total of 42 ant species were identified. The diversity parameters were consistent across the urbanization gradient. However, significant differences were observed in the ant assemblages between rural and urban, suburban and urban, but only marginal between rural and suburban. Eleven ant species were identified as indicator species (IV values between 50.7-80.7%). The ant assemblages were influenced by flora, ground cover, and soil variables.

Authors: Alam Shadab , Ahmad Reegu Faheem , Daud Salwani Mohd , Shuaib Mohammed
Published: April 2021

Electronic Health Record (EHR) is being used in most healthcare institutions to preserve and share health records instead of a paper-based method. Data records must be exchanged amongst various parties and users' privileges to manage access to their records should also be provided. In addition to the basic standards of secrecy, confidentiality and integrity of information, these facts further demonstrate the need for interoperability and consumer control to access their personal data. Electronic Health Record (EHR) system faces issues of protection of data, trust and management issues. In recent Covid-19 pandemic, various applications, tools and websites were launched that stores records. Also, many personal records related to health need to be shared among different parties for early detection, contact tracing, monitoring and the future prediction that requires accurate and reliable data. Simultaneously, the citizens will be hesitant in providing their personal details due to privacy concerns and social stigma. Blockchain technology has arisen as a powerful technology that can offer the immutability, confidentiality and user access properties of stored information and provided distributed storage. This paper analyses the blockchain suitability in EHR and its further applications in efficient Covid-19 pandemic management.

Published: April 2021

In the context of the COVID-19 pandemic, thousands of healthcare workers (HCWs) infected with COVID-19 have lost their lives worldwide. At the early stage of the epidemic, when COVID-19 was still not considered as a pandemic, a large number of Chinese HCWs were infected. Officials reported that more than 3,000 HCWs in Hubei contracted the virus at the early stage of the outbreak due to limited knowledge of the virus. Following reports of overloaded local hospitals, more than 42,000 medical staff, including those from the military, were dispatched to Hubei from across the country. At the peak of the fight, one in 10 intensive care medics in China were working in Wuhan. During fighting against COVID-19 in China, although a large number of HCWs were infected by SARS-CoV-2 in the early stages of the epidemic, the timely adoption of measures indicated that, a faster rate of diagnosis could be achieved, patients were isolated in-time, HCWs’ safety was prioritized, training on basic protective knowledge and unified management of HCWs was strengthened, and effective protective measures were implemented. This resulted in the accomplishment of zero SARS-CoV-2 infection among the 42,632 members of the national medical teams sent to Hubei, and the number of COVID-19 cases among HCWs in local hospitals also significantly decreased, thereby indicating that hospital-acquired infections of SARS-CoV-2 among HCWs are fully preventable.

Published: April 2021

Technology and smart devices have become ubiquitous staples in every aspect of human life. Given the rise of computation in everyday life, introducing technology to early childhood students requires exposure to logical thinking and problem-solving skills through programming approaches or computational thinking. This research addresses an inquiry into a comprehensive elaboration of the development of early childhood computational thinking. A novel programming toy was introduced as an educational tool based on designated themes in accordance with early childhood education curricula. Five stages were conducted to reveal parental and child engagement in robotics activities and later, interviews were conducted on children’s cognitive development from the parent's perspective. Children were observed exploring in various ways by concentrating and paying attention, doing the given activities and expressing their excitement and happiness. The notion that children learn from their social network environment was highlighted by the way in which the children involved in the KARIN programming toy’s hands-on activities were driven to be more actively engaged in the exercise. In addition to parent-student engagement, the use of the KARIN programming toy helps to shed light on how students in early childhood learn while away from their social relations during a pandemic.

Published: April 2021

Machining time estimation is essential for the due-date estimation of products as well as for production planning. Conventionally, machining time has been estimated by a computer aided manufacturing (CAM) system, which requires time and effort to create its numerical control (NC) program and requires machining expertise to operate it. In addition, among the problems with conventional methods, an error in the estimated machining time arises owing to the machine tool’s control characteristics. In this study, an artificial intelligence (AI)-based system capable of estimating machining time promptly and simply based on shape data without requiring any NC program is developed. The input data to the AI system are color information regarding the machined depths, which are used to estimate the rough-machining time, and color information regarding the machined surface curvature distributions to estimate the finish-machining time. Color information on the machined depths and machined surface curvature distributions is created using three-dimensional computer aided design (3D CAD) data. To build the AI system, the shape data and machining time data accumulated at the machining site are used, so that the machining time estimated reflects the machining method, machining expertise, and the machine tool characteristics employed.

Technology use in secondary level of English language teaching: A Literature Review
Authors: Luthfiyyah Roghibatul , Hafifah Gusti Nur , Ivone Francisca Maria , Tresnadewi Sintha
Published: April 2021

Technology has been widely used in the education field, especially for teaching language. Many teachers and students believe in the advantages of technology to enhance language learning. There have been many studies investigating the use of technology in secondary language classrooms. Some studies approve that technology can be applied to increase students' language competence. This paper comprehensively analysed the use of technology for English language teaching in the secondary level based on empirical studies. It reviews 57 articles from reputable journals and publishers. The existing literature shows that studying and reviewing the use of technology in ELT leads to a deeper understanding of its potential benefits. Many technology tools have been utilized to support the teaching of English skills. Kinds of learning activities that require technological tools and applications, such as presentation, discussion, assessment are also discussed. Additionally, problems and solutions encountered in the implementation of technology in secondary ELT levels are scrutinized in this study.

HIGHLIGTS:

Scholars need to set the content and pedagogy first before the technology to obtain meaningful and contextual experiments and discussion in academic circumstances.

The finding unveils a fact that technology use in the ELT context contributes more to students' learning strategies, such as learning motivation, engagement, collaborative work, rather than the improvement of students' learning outcomes.

This finding can be a rationale to rectify the common logical fallacy encountered among studies that claimed that technology can improve particular language skill.

It is currently accepted that language and culture are inseparable since culture becomes an essential aspect of learning a foreign language. In the Indonesian context, this broad understanding of the crucial role of culture in English teaching has raised challenges in different contexts for EFL teachers. The recent study focuses on Indonesian Junior High School teachers’ views on integrating culture in ELT and practices of textbook adaptation to help students build intercultural competence. Therefore, to meet these aims, a questionnaire and an open-ended question were employed to collect the data from fifteen participants teaching English at public and private schools in Indonesia. The study results reveal that Indonesian EFL teachers have positive attitudes on integrating intercultural competence in ELT. Still, some of the difficulties confronted by their implementation of textbook adaptation have been highlighted in promoting intercultural competence. This study suggests that EFL teachers in Indonesia should be provided with teacher training relating to textbooks adaptation and teaching culture. The implementation of ICT in ELT classrooms is also recommended. Finally, the redesign of the curriculum with more integrated intercultural competency materials should be taken into account.

HIGHLIGHTS:

The EFL teachers’ practices deal with textbook adaptation are not well implemented, although they believe that cultural competence in their teaching activities is crucial.

The English curriculum should give more room for teachers in serving the students based on their needs, preferences, and skills, especially for enhancing students’ mastery on the target language.

The coastal area of the Madura Strait stretches from Surabaya City to the east to Situbondo Regency and includes the southern part of Madura Island. The aim of this research is to map the suitability of the waters and coastal areas of the Madura Strait using GIS modeling. Mapping of the designation of the waters and coastal areas of the Madura Strait was carried out by overlaying spatial data covering bio-physical parameters including water transparency, pH, water substrate, temperature, salinity, and depth. The designation of water areas is divided into three classes, namely capture fisheries, tourism and conservation purposes. The spatial data used comes from several sources, namely the results of water quality surveys, Landsat 8 satellite imagery, bathymetry data / sea depth and Rupa Bumi Indonesia (RBI) maps at a scale of 1: 25,000. For water quality data comes from the results of a survey by the Marine and Fisheries Service of East Java Province in 2019 at 78 observation points in the waters of the Madura Strait. Water quality parameters used in GIS modeling are pH, salinity, brightness and temperature. The data for each observation point were then interpolated using the Kringing method. Landsat 8 satellite imagery is used to map the condition of the bottom substrate waters. Meanwhile, the depth data was downloaded from GEBCO (General Bathymetric Charts of the Oceans). The result of overlaying thematic maps shows that 37.69% (8586.69 km2) of the area of the Madura Strait is suitable for capture fisheries activities, then 10.28% (2341.02 km2) is suitable for marine tourism areas and 19.06 % (4343.4 km2) suitable for conservation areas. Meanwhile, 32.97% (7511.94 km2) can be used as conservation and tourism areas.

The present study aimed to evaluate the effects of dietary copper nanoparticles (Cu-NPs) and vitamin C (VC) supplementations on rainbow trout (Oncorhynchus mykiss) juveniles. Six trial diets were supplemented with Cu-NPs and VC including 0/0 (T1, control diet), 0/250 (T2), 0/500 (T3), 2/250 (T4), 2/500 (T5), and 2/0 (T6) mg Cu-NPs/VC per kg diet. After the feeding trial for 60 days, the fish were challenged with Yersinia ruckeri and the survival rate was calculated for 15 days. Based on the data analysis, weight gain (WG), feed conversion ratio (FCR), specific growth rate (SGR), protein efficiency ratio (PER), lysozyme, alternative complement activity (ACH50), catalase (CAT), glutathione peroxidase (GPX), hematocrit (Hct) and mean corpuscular volume (MCV) were significantly (p < 0.05) affected by the Cu-NPs factor. Meanwhile, VC was a significant factor for hemoglobin (Hb) and superoxide dismutase (SOD) (p < 0.05). The results showed that the Cu-NPs and/or VC-supplemented diets improved WG, FCR, SGR, PER, lysozyme, ACH50, SOD, CAT, GPX, Hb, Hct, and MCV when compared with the control group (p < 0.05). The expressions of TNF-α, IL-1ß, IL-10, SOD, CAT, and GPX genes were significantly (p < 0.05) decreased in the fish fed on T3, T4, and T5 diets versus the control. In addition, the dietary Cu-NPs and VC supplementations significantly enhanced resistance against pathogens and led to the control of infection in rainbow trout. In conclusion, Cu-NPs and VC administered as feed additive at 2/250–500 mg/kg elevated the growth performance, antioxidant capacity, and health of rainbow trout.

Background. The prognostic value of lactate dehydrogenase (LDH) in colorectal cancer patients has remained inconsistent between non-metastatic and metastatic settings. So far, very few studies have included LDH in the prognostic analysis of curative-intent surgery for colorectal liver metastases (CRLM).Patients and Methods. 580 consecutive metastatic colorectal cancer patients who underwent curative-intent CRLM resection from Blinded for peer review (434 patients) and Blinded for peer review (146 patients) treated in 2000-2019 were enrolled. Overall survival (OS) was the primary endpoint. Cox regression model was performed to identify the prognostic values of preoperative serum LDH levels and other clinicopathology variables. A modification of the established Fong CRS scoring system comprising LDH was developed within this Chinese population.Results. At the median follow-up time of 60.5 months, and median OS was 59.5 months in the pooled cohort. In the multivariate analysis, preoperative LDH > upper limit of normal (250 U/L) was the strongest independent prognostic factor for OS (HR 1.73, 95% confidence interval [CI], 1.22-2.44; P < .001). Patients with elevated LDH levels showed impaired OS than patients with normal LDH levels (27.6 months vs. 68.8 months). Five-year survival rates were 53.7% and 22.5% in the LDH-normal group and LDH-high group, respectively. Similar results were also confirmed in each cohort. In the subgroup analysis, LDH could distinguish the survival regardless of most established prognostic factors (number and size of CRLM, surgical margin, extrahepatic metastases, CEA and CA19-9 levels, etc.). Integrating LDH into the Fong score contributed to an improvement in the predictive value. Conclusion. Our study implicates serum LDH as a reliable and independent laboratory biomarker to predict the clinical outcome of curative-intent surgery for CRLM. Composite of LDH and Fong score is a potential stratification tool for CRLM resection. Prospective, international studies are needed to validate these results across diverse populations.
