Published: November 2022

With the development of modern technology and the rise of artificial intelligence, the application scenarios of identity authentication technology are becoming more and more complex, especially the current situation of the spread of the novel coronavirus, the traditional identity authentication technology can no longer meet people's actual needs, and the society urgently needs a secure and convenient identity authentication technology. Voice print recognition technology is an identity recognition method that uses specific feature extraction methods to extract the features that can identify the speaker's identity from the original speech input, and then uses these features to identify the speaker's identity. Aiming at the above problems, this paper proposes a deep learning-based voicing recognition algorithm, which is based on the theoretical knowledge of deep learning. The research work includes the following aspects: providing convolutional network to extract features; The "speech feature template library" is established by massive training. Research on matching and recognition algorithm; Research on check-in system based on voice print recognition. Based on this algorithm, this paper designs and implements a voiceprint recognition check-in system with clear interactive interface. The system has the functions of adding members, refreshing the voice library, checking in with the voice print, clearing the results and so on. The system interface will display the data of the voice print library and the historical check-in record, as well as the current recognition results, accuracy and check-in time. The average recognition rate of the system is about 95%, which can meet the requirement of practical application.

Published: November 2022

The basic task of feature learning is to use algorithms to allow machines to automatically learn useful data and its features during the model building process. The quality of the learned features will greatly affect the results of downstream tasks. Early feature learning methods relied on handcrafted features. Thanks to the development of deep learning, feature learning methods based on convolutional neural networks have greatly improved the quality of features. However, with the increasing scale of training data and the increasing complexity of modeling tasks, deep neural network Transformer based on self-attention mechanism and parallel data processing has gradually become a new research hotspot. Transformer can adaptively and selectively select contextual information and key semantic information in a scene by covering attention networks and fully connected layers and has become an important research area for computer vision and natural language processing tasks. This paper reviews the basic principles and development of Transformer, focuses on its application in CV and NLP, and analyzes effective Transformer-based models. Finally, the challenges faced, and future trends of transformer models are summarized.

Published: November 2022

Aiming at the sound absorption problem of anechoic coating in water seepage state, firstly, the sound absorption coefficient of anechoic coating in infinite water area with steel plate as backing is calculated based on transfer function method and finite element method, anAd the solution results are compared with the analytical result of uniform layered medium to verify the correctness of the solution method. Secondly, the calculation model of cavity containing anechoic coating with different seepage proportion is established to analyze the influence of water seepage on the sound absorption performance of anechoic coating. The calculation results show that within the calculated frequency band, water seepage proportion has different influence characteristics on different frequency bands of anechoic coating, and with the aggravation of water seepage, the peak point of sound absorption moves to medium and low frequency, and the singular value point of sound absorption coefficient moves to high frequency; and the singularity of the valley value of the sound absorption coefficient is mainly due to the change of the cavity resonance mode. The results of this paper can provide some reference for the acoustic performance evaluation of abnormal state of anechoic coating.

The severe circumstances caused by COVID-19 make online education the best replacement for regular face-to-face education for continuing the education process. One year ago, and till now most schools adopted online learning during this pandemic shutdown, which indicates the applicability of this teaching methodology. However, the efficiency of this method needs to be improved to guarantee its effectiveness. Although face-to-face teaching has many advantages over online education, there is a chance to promote online learning by utilizing the recent techniques of artificial intelligence. From this perspective, we propose a framework to detect and recognize emotions in the speech of students during virtual classes to keep instructors updated with the feelings of students so and can behave accordingly. The approach of detecting emotions from the speech is much more helpful for cases when turning on the cameras at the student's side could be embarrassing. This case is very common, especially for schools in Middle East countries. The proposed framework can also be applied to other similar scenarios such as online meetings.

One of the main methods used to provide security for medical records when exchanging these records through open networks is digital watermarking. In order to preserve the privacy of patients, this system also requires a means to secure images. In this paper, a watermarking based on discrete wavelet transform (DWT), and discrete and discrete cosine transform (DCT) in cascade provides more robustness and security. DCT divides the image into low and high-frequency regions, watermarking message can be embedded into low-frequency regions to prevent distortion of the original image. DWT splits the image into four frequency coefficients; horizontal, vertical, approximation, and detailed frequency component. The judgment factors for the strength of the watermark system are robustness, invisibility, and embedded message capacity. Invisibility means transparency of the watermark logo or data in the original or host image without any distortion. Capacity data payload means the size of the embedded image which is related to the amount of data or logo size that will be embedded in the host image. Robustness refers to the capability of the watermark to stand with the host image operations. In this paper, we propose an optimizer to trade-off between robustness, invisibility, and message capacity. Three metrics were employed to assess the results achieved by the proposed approach, namely, Peak Signal-to-Noise Ratio (PSNR), Normalized Cross Correlation (NCC), and Image Fidelity (IF). The achieved results confirmed the effectiveness and superiority of the proposed approach for real-world digital watermarking applications.

Identifying the talented university students plays an important role in higher education. Special curriculum can be developed for these students as an outcome from the identification process. This curriculum can be compacted, clustered, and accelerated to match and exploit students’ abilities. Current methods for identifying talented students are based on simple identification test in the form of a questionnaire, which is developed for specific age. However, this method of identification cannot cover all aspects of student abilities and inaccurate as it not an iterative process. In this paper, a machine learning approach is proposed for identifying talented students based on their academic performance, which is evaluated repeatedly through their study. In this approach, we measure a set of features representing student abilities, then cluster them based on their features similarity. The proposed approach is applied on a set of 100 university students and shows promising results in identifying the talented group. To emphasize their talent, this group is guided to participate in national competitions that match their abilities, and they could achieve significant ranks.

Authors: Ferst Marklea , Melo Juliana da Silva
Published: November 2022

A população de pessoas com deficiência ou mobilidade reduzida vem aumentando consideravelmente nos últimos anos. No Brasil, cerca de 35,8 milhões de pessoas possuem deficiência visual, sendo essa a mais recorrente no país e no estado do Amazonas, onde encontramos cerca de 651,2 mil pessoas com esta deficiência. Considerando a crescente demanda de pessoas com deficiência visual no estado, espera-se que os museus e centros culturais existentes no local proporcionem acessibilidade a esse público. Dessa forma, utilizando o Centro Cultural Palacete Provincial, que fica localizado na capital do estado e que possui um fluxo majoritário de visitantes locais, este estudo possui como objetivo geral analisar a acessibilidade no Palacete Provincial para o atendimento do turista com deficiência visual ou baixa visão. Trata-se de uma pesquisa descritiva, bibliográfica e de abordagem qualitativa, em que foram realizadas visitas guiadas de 5 pessoas com deficiência visual e aplicada uma pesquisa após a visita. Como resultados, verificou-se que o Centro Cultural Palacete Provincial não atende às necessidades de uma pessoa com deficiência visual relativamente a acessibilidade dos museus que integram o espaço. Como contribuição teórica, esta pesquisa, além de trazer informações históricas e descritivas do Centro Cultural objeto de estudo, apresenta a literatura a respeito do turismo acessível e a legislação brasileira a despeito da acessibilidade. Como contribuição prática, apresenta subsídios que podem contribuir para sensibilizar os gestores da necessidade de se investir em acessibilidade nos centros culturais, podendo ser replicada em outros museus e centros culturais.

O filósofo David Lapoujade discorre sobre a obra do escritor de ficção científica Philip K. Dick. Partindo de uma leitura muito particular, aponta como principal característica de seu universo ficcional o pensamento através de mundos. Mundos pensantes que colocam em questão a realidade dos próprios indivíduos, agora meros coadjuvantes. Em Dick, as fronteiras entre os humanos, as máquinas, os mundos, o sonho e a vigília estão irremediavelmente comprometidas, uma vez que somos confrontados por mundos que operam por meio de um delírio generalizado. Lapoujade nos mostra que o objetivo do autor é questionar o estatuto da realidade mesma.

Treading Lightly: China’s Footprint in a Taliban-led Afghanistan
Authors: Zhou Jiayi , Su Fei , Yuan Jingdong
Published: November 2022

This SIPRI Insights Paper provides a preliminary assessment of China’s attitudes to and policies on Afghanistan since the August 2021 Taliban takeover. It examines the scope of China’s security, economic and humanitarian interests, and the depth of its engagement so far. It finds that China’s footprint has been minimal not only due to China’s non-interference policy but also to a range of broader challenges: the militant extremist groups that continue to operate on Afghan soil, the risks of investing in a country where the government remains unrecognized by any member of the international community and a fragile stability that is far from conducive to long-term planning. While there may be prospects and opportunities for China to contribute to Afghan stability and development, particularly from a broader regional perspective, current realities mean that China’s overall approach to Afghanistan will remain cautious, pragmatic and limited.

Authors: Demir Aydin , Cakiroglu Evren Osman , Aydin Ismail
Published: November 2022

The processing of wood-based panels such as plywood, particleboard and fiberboard, which are widely used in the furniture industry, with CNC (Computer Numerical Control) milling machines has been increasing recently. Even though CNC milling machines have many advantages for furniture producers, it is difficult to set process parameters to obtain the desired surface quality of the material. Therefore, it is necessary to determine the most suitable of these parameters for the surface quality of each wood-based panel. This study aimed to determine the effects of processing parameters on the surface quality of plywood, particleboard and medium density fiberboard (MDF) panels processed in CNC milling machines. Furthermore, the average surface roughness values of these panels were compared after CNC processing. Three spindle rotational frequencies (10.000, 14.000 and 18.000 rpm), three feed rates (5, 7, and 9 m/min) and two cutting tool diameters (2 and 5 mm) were selected as CNC processing parameters. To determine the surface quality of wood-based panels, the surface roughness measurements were performed according to DIN 4768 standard and three surface roughness parameters (Ra, Rmax and Rz) were determined. According to the results of this study, it can be concluded that the surface roughness values of wood-based panels decreased with increasing spindle rotational frequency and feed rate, while they increased with increasing cutting tool diameter. Among the wood-based panels used in this study, the lowest average roughness values were obtained for plywood samples.
Fracture Behavior of Wood Under Mode I Loading in Tangential Direction
Authors: Konukcu Arif Caglar
Published: November 2022

The aim of this study was to determine the fracture behavior of southern yellow pine (Pinus taeda L.) and red oak (Quercus falcata) wood under mode I loading in the tangential-radial and tangential-longitudinal crack propagation systems by a compact tension test method. The results of the study indicated that, in general, red oak had a significantly different fracture behavior than southern yellow pine for each of the two crack propagation systems. The fracture toughness was higher in the tangential-radial crack propagation system than that in the tangential-longitudinal crack system, but there was no significant difference between the two crack propagation systems for southern yellow pine. The specific fracture energy of the tangential-longitudinal crack propagation system for both wood species was significantly lower than that of the tangential-radial crack propagation system. It means that more energy per unit area for the tangential-radial crack propagation system was needed to separate a wood sample into two halves. The difference in the fracture behavior of wood by the crack propagation system can be explained by the structural features of the tested samples since the crack propagation of the tangentialradial system crosses the annual ring and wood fibers can bridge the crack surface.

Authors: Uhrenholt Jonas Nygaard , Kristenses Jesper Hemdrup , Adamsen Sofie , Jensen Steffen Foldager , Colli Michele , Waehrens Brian Vejrum
Published: November 2022

The relation between digital technologies of the industry 4.0 agenda and the circular economy agenda is being coined as mutually beneficial in the twin transition agenda. However, the agenda is in a pre-paradigmatic stage where the dual relationship is primarily discussed at a conceptual level. At the same time, manufacturers are challenged in building sustained performance improvements from either transition. Therefore, this study adopts the multiple case study methodology for investigating the synergetic relation between the internet of things (IoT) and the circular economy (CE) in ten Danish manufacturers as representations of the constituting constructs of the twin transition agenda. Accordingly, this study proposes two empirically based propositions for the synergetic relationship between the two: IoT enables the circular economy engagement from the cumulative build-up of data capabilities and their connection to particular value propositions. At the same time, the value and purpose of digital technology are elevated to a strategic perspective when adopting circular economy as a design parameter

Remdesivir: a strategy to face the COVID-19 virus
Authors: Bessa Grasiela , Alcântara de Castro Michele , Barbosa Ferreira dos Santos Ramila , De Sousa Pinto Murillo , Vieira de Moraes Filho Aroldo
Published: November 2022

In December 2019, a new type of coronavirus was found to have emerged and the World Health Organization declared a state of public health emergency. In view of this, Remdesivir has been identified in many countries as a possible candidate for the treatment of Sars-Cov-2. Given these assumptions, this paper aims to highlight the current evidence on the mechanism of action of this drug in cells infected with COVID-19 through a literature review. Remdesivir is defined as a nucleoside analog prodrug substituted with 10-cyano. Its main function is to inhibit viral replication by competing with endogenous nucleotides for viral RNA incorporation. In a randomized double-blind study, intravenous Remdesivir had no efficacy on time to clinical improvement, mortality, or time to viral clearance in patients with severe COVID-19. In another study patients who received Remdesivir had a 10-day faster recovery compared to those who received placebo. It is concluded that one study was able to satisfactorily demonstrate the use of Remdesivir in patients with COVID-19, as patients had a short recovery time compared to placebo. However, more studies are needed to prove the efficacy of the drug to combat coronavirus.

The Sars-CoV-2 pandemic, called COVID-19, leads to a turning point in the historical process of changes in agri-food markets, especially with regard to food safety and quality. Although the reflections in this article were made at the beginning of the pandemic, its objective was to highlight the difficulty of the fish market to respond to the resulting impacts, a difficulty that stems from the failure to incorporate parameters inherent to foods with visibility and value, covering characteristics about safety and quality through technical aspects of production, sociocultural aspects on who, where and how the food is produced, ecological aspects of food production, nutrition and health that could result in segmentation. It is based on a literature review focused on structural obstacles in fish market, obstacles that result on more intense pandemic impacts. The situation generated by the Sars-CoV-2 pandemic is pointing to a radicalization of discussions on food that will culminate in the events associated with the Food Systems Feed Summit in 2021 around the principles raised by the SDG2030 Agenda. This article is divided into four parts. In the first part, the main characteristics of the fish market will be presented. In the second, the main profile of product consumption. The third part will deal with the impacts of the coronavirus on the fish market based on recent positioning of some representatives of large-scale fishing and commercialization sector. The fourth will bring the final considerations.

Marine plastics have been shown to affect all organisms across the trophic levels including the microbial communities, influencing their community assembly, composition, metabolic processes, and ecosystem functions. Thus, studying plastic-microbe interactions in the marine environment is important in understanding its implications alongside the growing issue of plastic pollution. The Philippines, despite being suggested as the third-largest contributor to marine plastic debris, currently does not have any existing national research programs on basic plastics research, resulting in our limited understanding of the extent and implications in the country. This paper then reviews the current status and knowledge of the plastic-microbe association focusing on how plastic surfaces serve as a new environment for marine microbes, how this system could become dispersal mechanisms of unwanted microorganisms, and how microbes possibly contribute to the biodegradation of plastics in the marine environment. These also translate to possible research opportunities for Filipino scientists to work on the topic.

Shifting from conventional transplanting to direct seeding of rice is an alternative option to save irrigation water and reduce labor cost. Weeds are one of the major challenges in direct seeding. Field experiments in split-plot design were conducted to evaluate the effects of different water and weed management modes on the weed density, grain yield, and water productivity of direct wet-seeded rice during two dry seasons (DSs) in Nueva Ecija, Philippines. Three water management (W) modes were used: continuous flooding (CF); safe alternate wetting and drying (AWD); and modified CF (mCF). The four weed management (M) modes were: unweeded (UW); hand-weeding at 21 and 42 days after seeding [DAS] (HW); application of pre-emergence herbicide [pretilachlor] at 5 DAS (PR); and application of post-emergence herbicide [bispyribac sodium] at 15 DAS (PO). M modes showed significant effects (p < 0.05) on the weed density and grain yields in both years, with UW obtaining the lowest grain yield and highest weed density. No significant differences in grain yields were noted among weed control treatments. They only increased grain yields by 18–52% relative to UW. HW and PR treatments showed maximum yields. The W modes did not affect the grain yields nor the weed density, but water productivity was highest in AWD in both years. The higher grain yield and lower total water input in AWD maximized water productivity relative to the conventional practice of CF.

The study characterized the quality properties of freeze-thawed quick-frozen intermediate amylose cooked rice PSB Rc 18 (Oryza sativa L.). Scanning electron microscopy (SEM), texture profile analysis (TPA), and differential scanning calorimetry (DSC) were employed to monitor structural, textural, and thermal properties including retrogradation in quick-frozen rice as subjected to 1, 3, and 5 freeze-thaw cycles (FTCs) (–18 °C for 16 h; 10 °C for 8 h). Data from SEM, TPA, and DSC explained progressive deteriorative quality changes with increasing FTC. The SEM micrographs revealed the formation of honeycomb structures. The TPA results showed significant (p < 0.05) increase in hardness, cohesiveness, chewiness, springiness; as well as a decrease in adhesiveness. The DSC analysis demonstrated the decreasing trend of thermal transition temperatures. Based on the obtained results, it is recommended that quick-frozen cooked rice should not be exposed to more than 3 FTCs.

Changes that occurred in the agriculture-food system – for instance, increase in disease incidence compounded by climate change, as well as changes in contractual arrangements and policies – pose challenges to small-scale Cavendish banana farmers in the Davao region, the top producer of Cavendish in the Philippines, in terms of their vulnerability and ability to survive. The current challenges can be addressed by increasing the opportunity of small-scale farmers to increase their profit by exploring alternative enterprises. The current system of the farmers is to allocate their entire harvested Cavendish bananas into the contractual market or the spot market. While these farmers can improve their profit by processing raw bananas into alternative products such as banana flour, very few of them have embarked on this enterprise. One reason for this is the limited understanding of this market potential and its profitability relative to contractual or spot market. Hence, in this study, we explored through a model simulation – a novel yet simplistic approach – different scenarios of a farmer’s profit as they venture into the banana flour market. Some model considerations include flour demand, the volatility of spot market prices, and banana production rates. Our simulations show that the total profit of the model farmer varies significantly with different allocations of bananas to contractual or spot markets for various demands in the banana flour market. Additionally, with our model assumptions, model farmers can further increase their profit if all their unsold fresh bananas have been processed to banana flour and sold them during high demand. Finally, we highlight the novelty of our approach as a diagnostic tool to initially assess the profitability of a commodity among different market options especially when there are unexplored scenarios and data is scarce.

Based on the most recent national nutrition survey from the Food and Nutrition Research Institute (FNRI), the number of Filipino children who are being exclusively breastfed slightly declined from 52.3% in 2013 to 48.8% in 2015. Workplace barriers and familial support may influence the decision of exclusive breastfeeding practices. Furthermore, the educational attainment of the mothers may also influence their employment status affecting their decision to breastfeed or not. The aim of this study is to find a correlation among employment status, educational attainment, and civil status of lactating mothers with their practice to conduct exclusive breastfeeding. Twenty-three (23) lactating mothers from Makati, Taguig, and Mandaluyong cities answered a questionnaire identifying their employment status, educational attainment, and if they practiced exclusive breastfeeding or not. Association of the identified factors was measured using Cramer’s V coefficient. Results generated in the study showed a strong relationship between employment status, educational attainment, and civil status with the practice of exclusive breastfeeding. Mothers who did not practice exclusive breastfeeding were found to be those who were employed, married, and with higher educational attainment. Based on the results it is recommended that more means, such as having nursery rooms in the company and allowing flexible working hours for the first two months from maternity leave to working mothers for them to be able to practice exclusive breastfeeding shall be provided. Mothers should also be given more information on how to provide breastmilk to their infants even if they are not at home, such as providing education on storing milk at home. Further studies are also encouraged to look into more factors, which affect breastfeeding practice.

This paper presents the newly documented single specimen of the North Philippine temple pitviper (Tropidolaemus subannulatus), one of the venomous endemic snakes of the Philippines. The species has never been recorded in Cebu Island in the last two waves of survey in 1986 and 2016. The new record for Cebu Island on 13 Apr 2018 was a male juvenile T. subannulatus in a diverse forest over limestone in Mount Lantoy key biodiversity area (KBA), with an elevation of 648 m having geographic coordinates of 9.91395ºN and 123.51207ºE in Barangay Cansuje, Argao, Cebu, Philippines. The specimen was recorded in the permanent vegetation plot no. 1, established within the secondary natural forest, perching on the vines (Piper sp.). Some tree species found within the collection area were the following; Garcinia rubra, Ficus ampelas, Canarium asperum, Calophyllum blancoi, Gomphandra luzoniensis, and Goniothalamus almeri. The distance of occurrence from the ground is approximately 3 m. It seemed that the microhabitat characteristics of Mt. Lantoy KBA, particularly the forest over limestone in Barangay Cansuje, is favoring the survival of T. subannulatus.
Water Pollution in India: An Overview

Most ancient civilizations grew along the banks of rivers. Even today, millions of people all over the world live on the banks of rivers and depend on them for their survival. All of us have seen a river large or small either flowing through our town or somewhere else. Rivers are nothing more than surface water flowing down from a higher altitude to a lower altitude due to the pull of gravity. One river might have its source in a glacier another in a spring or a lake. Rivers carry dissolved minerals organic compounds, small grains of sand gravel and other material as they flow downstream. Rivers begin as small streams which grow wider as smaller streams and rivers join them along their course across the land. Eventually they flow into seas or oceans. Unfortunately most of the world’s major rivers are heavily polluted. The pollution of environment is the gift of the Industrial revolution prior to this the agrarian cultures created significant environment deforestation and overgrazing. The Environmental degradation is a byproduct of modern civilization. Water Pollution is a major global problem which requires on going evaluation and revision of water resource policy at all levels. It has been suggested that water pollution is the leading worldwide cause of deaths and diseases and that it accounts for the deaths of more than 14,000 people daily. An estimated 580 people in India die of water pollution related illness every day.
