Authors: Nguyen Ket Doan
Published: June 2024

Automatic Speech Recognition, also known as ASR, has grownexponentially over the past decade and is used to recognize and translate humanspeech into readable text automatically. However, Vietnamese SpeechRecognition faces critical challenges such as easy to make mispronunciations aswell as a huge variant in Vietnamese speech. In this work, we dive into thedifficult challenge of Mispronunciation Detection (MD) in the Vietnameselanguage. As such a tonal language, Vietnamese is not only based on consonantsand vowels but also on variations in pitch or tone during pronunciation. In thispaper, we propose DaNangVMD model for detecting mispronunciations inVietnamese speech based on the audio speech and canonical transcript. Byleveraging multi-head attention-based multimodal representation from theembeddings of the phonetic encoder and linguistic encoder, DaNangVMD aimsto provide a robust solution for accurate mispronunciation detection anddiagnosis. Throughout the extensive evaluation, the proposed DaNangVMDexhibits superior performances rather than that of the PAPL baseline models by15% in F1 score and 13 % in accuracy.

Crianzas y cuidados: mujeres de origen africano en las ciudades de México y Querétaro, siglo XVIII
Authors: Velázquez Gutiérrez María Elisa
Published: June 2024

Este artículo tiene el objetivo de reflexionar sobre dos actividades desempeñadas por mujeres de origen africano en la Nueva España: la crianza de los niños y el cuidado de enfermos o ancianos en las ciudades de México y Querétaro en el siglo XVIII. Se analiza la importancia de estas tareas, como parte de los trabajos forzados y obligados que realizaban, pero también   como medios para establecer relaciones y vínculos afectivos, y en ocasiones la libertad y mejores condiciones de vida. Se hace hincapié en la importancia de la convivencia y el intercambio entre diversos grupos y en los prejuicios, que, sobre todo en el siglo XVIII, se desarrollaron sobre las costumbres de “negras y mulatas.”  El análisis de estos casos se basa en los conceptos de reproducción y recreación cultural de los antropólogos Mintz y Price, así como de estudios sobre la importancia de los cuidados en la vida cotidiana de tradición antropológica.

Published: June 2024

Using two solution-based techniques—solution growth technique (SGT) and sequential ionic layer adsorption and reaction (SILAR) AlS: ZnS alloyed thin films were successfully produced on glass substrates. The sources of Al, Zn, and S were aluminum sulphate (AlSO4.7H20), zinc sulphaate (ZnSO4.7H20), and sodium thiosulphate (Na2S2S03). The complexing agent that was utilized was ethylene diamine tetraacetic acid (EDTA). Using a Master Chef Annealing Machine, the deposited alloyed samples were annealed between 373K and 523K. The scanning electron microscope (SEM) and X-ray diffractometer (XRD) were used for the crystallographic investigations. Samples R1 and R6 AlS: ZnS alloyed thin films exhibit well-defined peaks in their XRD pattern, indicating that they are polycrystalline in nature. We computed their grain sizes. Spectroscopy using Rutherford backscattering (RBS). Analysis using Rutherford backscattering spectroscopy (RBS) verified the composition of aluminum, zinc, and sulfur in the alloyed thin films. The microstructure of the deposited alloyed thin films is revealed by the results of surface electron microscopy. Two significant semiconductor materials that have potential uses in optoelectronics, photovoltaics, and sensing devices are aluminum sulfide (AlS) and zinc sulfide (ZnS). Depositing these materials in thin films at a reasonable cost and with good efficiency is possible with dual solution synthesis. However, the annealing temperature, a crucial factor in establishing the crystal structure, morphology, and optical properties of these films, can have an impact on their structural characteristics. Prior studies have examined how the annealing temperature affects the structural characteristics of AlS and ZnS thin films separately; however, the dual solution-produced AlS: ZnS thin films have not received as much attention. The purpose of this work is to examine how the annealing temperature affects the crystal structure and surface morphology of AlS: ZnS thin films. The results of this investigation can offer significant understanding regarding the refinement of the annealing temperature to produce superior AlS: ZnS thin films for a range of uses. Based on their properties, sulphide alloyed thin films could find applications in microelectronics, window coating, and antireflection coating. They work well as coatings for eyeglasses and as absorber layers for photocells, among other applications.

Published: June 2024

Breast cancer is one of the leading causes of death in Canadian women.1This cancer can be detected early through screening and allow for higher chances of survival. However, the Canadian Cancer Statistics Advisory Committee found that it is still being diagnosed at late stages, even with organized screening programs implemented in Canadian provinces.1 In Ontario, mammography is recommended every two years for women ages 50-69 years where they receive a medical referral letter invitation, but women are still found to present in clinics with no history of screening or advanced cancer.2 In 2017, 26500 breast cancer cases were found and in that 5000 women did not survive, with a majority of these women being immigrant. Canada is a multicultural country where more than 20% of the populations are immigrants, but yet more immigrant women die from breast cancer than non-immigrant women.3,4 However, screening participation rates remain lower in immigrants than non-immigrants,5 possibly being fatal. It’s important to know the causes of screening avoidance. Thus, the purpose of this literature review is to investigate the avoidance of breast cancer screening of immigrant women in Canada.

Authors: Wardhani Citra Rachmania , Alamsjah Mochammad Amin , Sulmartiwi Laksmi
Published: June 2024

Lemuru fish (Sardinella lemuru) is rich in omega-3 so it is widely used as raw material for fisheries production such as fish canning which produces by-products in the form of crude fish oil which needs to be purified by adding adsorbents so that it becomes pure fish oil. The adsorbent that can be used in the purification of fish oil is activated charcoal. Fish oil can be used as raw material for making added value products such as margarine. The aim of this study is to analyse the characteristics of margarine as a value-added product made from fish oil. Research shows that purification with activated charcoal produces fish oil with %FFA and PV that are in accordance with IFOS. Fish oil margarine in this study showed organoleptic value of colour 7.4 and aroma 7.07, emulsion stability 100%, %FFA content 0.28 ± 0.08, PV 1.6 ± 0.173, and higher 0.39% EPA and 2.58% DHA content compared to commercial margarine. In previous study showed margarin from sardine fish oil contains 19.5% EPA and 10.5% DHA which is also not found in commercial margarine from palm oil. The difference in EPA and DHA content between this study and previous study may be due to the fact that the fish oil in this study was obtained from by-products of canning processing with high temperatures which may cause a decrease in fatty acid levels due to protein denaturation.

Drinking water quality is a crucial factor that influences livestock productivity. Regular evaluation of the quality of livestock drinking water is an essential activity. Blitar Regency is known as a center for egg production from laying hens (Gallus domesticus). This study aims to evaluate the quality of livestock drinking water and provide a literature review regarding the potential for improvement through phytoremediation methods. This research method involves laboratory analysis and literature review. Laboratory analysis is carried out to determine the quality of water chemical parameters, then the results are compared with livestock drinking water standards regulated by Regulation of the Minister of Health of the Republic of Indonesia Number 32 of 2017. If a discrepancy is found with the standards, it is continued with a literature study regarding the use of phytoremediation methods as a solution. Analysis of chemical parameters, including ion levels, using a reagent kit with the help of Spectroquant Pharo 300 UV Vis spectroscopy. The results of the analysis involve iron, fluoride, manganese, nitrate, nitrite, cyanide, hardness, cadmium, zinc metal and sulfate. All parameters meet quality standards, except for Fluoride (F-) levels which exceed the threshold of 1.5 mg/L, caused by the use of groundwater sources or wells which have the potential to have higher mineral content than surface water. The potential impacts of high fluoride levels on laying hens include reduced egg production, impaired growth, reproductive disorders, decreased water consumption, and decreased body weight. The literature review highlights phytoremediation methods involving plants as an economical and effective solution. Afforestation, such as planting grass or bushes around livestock areas and wells, or through creating ponds with aquatic plants, can significantly reduce fluoride levels in livestock drinking water.
Kadar Silika (SiO2) terhadap Kelimpahan Diatom Bentik di Sungai Jamblang Kabupaten Cirebon
Authors: Haque Maharani Zahiratun , Afiati Norma , Jati Oktavianto Eko
Published: June 2024

Jamblang River is a concern because it has a very turbid water color due to natural stone mining activities processed by the natural stone industry. One of the natural stones produced at the location of the Jamblang river is andesite rock which has a constituent component is silica. Silica is the second most abundant element in the Earth's crust after oxygen. Silica usually comes from minerals and rocks that dissolve in water. In fresh water, quartz silica is less soluble than amorphous silica. Enrichment of nutrients with silica favors the growth of diatoms, since diatoms need silica for cell wall biogenesis. The amount of silica present in water is not immediately absorbed by diatoms. The sampling method used is the purposive sampling method. The sampling locations set are 4 locations. The most interesting location is location 2 because there are 38 natural stone industries scattered around the location. There is also a simple linear regression statistical test on SPSS which shows the influence of silica levels on the abundance of benthic diatoms in the Jamblang river. The value of Sig. 0.000 shows that there is an influence of silica on plankton abundance in water because the value is < 0.05. The lowest silica content obtained at location 2 is also supported by the least abundance of diatoms found. The low abundance of diatoms is thought to be caused by high TSS numbers, low observed brightness, and low DO numbers.

The new policies included in the independent curriculum certainly have several different aspects. One of the differences here is in the teaching tools. In the independent curriculum, the Learning Implementation Plan (RPP) is referred to as a teaching module. Teachers can choose or even modify their own teaching modules that have been provided by the central government. Teachers need to develop teaching modules, but in reality there are still many teachers who experience difficulties in developing teaching modules. This research aims to determine the difficulties experienced by high school biology teachers in developing teaching modules. This study used qualitative research methods. The research subjects taken were the population of class X and XI Biology teachers at SMA Negeri 2 Temanggung, SMA Negeri 1 Candiroto, and SMA Negeri 1 Pringsurat. Data collection techniques used in research include observation, interviews and questionnaires. The research results show that the difficulty of Biology teachers in developing teaching modules is 45%. The level of difficulty is found in indicators of analysis and mapping of student needs, determining the dimensions of the Pancasila student profile, clarity of learning objectives, organizing teaching materials, determining learning models, determining and carrying out assessments, evaluating learning and following up on teaching modules, as well as difficulties in analyzing learning outcomes. will be reduced to a teaching module. The factors that make it difficult for Biology teachers to develop teaching modules are: 1) the number of students; 2) difficulty reading Learning Outcomes (CP); 3) the material is very short and unsystematic; 4) time constraints; 5) minimal reference for the implementation of the assessment; and 6) level of technological mastery. Thus, it can be concluded that the difficulties of high school biology teachers in developing teaching modules in the independent curriculum at Temanggung driving schools are in the "sufficient" category.

Background: Temporomandibular disorder (TMD) is a set of conditions with a multifactor etiology that affect the temporomandibular joint and muscles of mastication. Objective: The aim of the present study was to assess the effectiveness of treatment for myofascial TMD using acupuncture and low-level laser therapy compared to occlusal splint. Methods: 23 patients recruited through announcements and online publications. The diagnosis of TMD was confirmed using the Research Diagnostic Criteria for TDM (RDC/TMD) and all participants had moderate to severe pain upon palpation. The participants were randomly allocated to three groups: Group 1–occlusal splint; Group 2–10 sessions of acupuncture (once per week); Group 3–low-level laser therapy at 48-h intervals until the remission of symptoms or until completing 10 sessions. The participants were submitted to evaluations before and after treatment as well as 30 days after the end of treatment involving the determination of pain intensity, maximum vertical mandibular movement, as well as extraoral and intraoral palpations e analyze intra e extra group. Results: Statistically significant improvements in pain intensity were found in the acupuncture and laser groups (p=0.002). Improvements in the masseter and temporal muscles as well as the lateral pole of the temporomandibular joint were achieved with acupuncture and laser. Significant improvement was found in the posterior mandibular region using all three treatment modalities. Improvement in the submandibular region was only achieved with laser therapy. Conclusion: Treatments with acupuncture and low-level laser were more effective at reducing symptoms in individuals with myofascial TMD compared occlusal splint.
