Authors: Vdovin K. N. , Pivovarova K. G. , Feoktistov N. A. , Ponamareva T. B.
Published: October 2020

Zinc sulfate is the main component in the composition of the acidic zinc plating electrolyte. Deviation in the electrolyte composition from the optimum content leads to destabilization of the electrolysis process and deteriorate the quality of the resulting zinc coating. The proper quality of a zinc coating obtained by galvanic deposition can be ensured only with timely monitoring and adjustment of the electrolyte composition. A technique of X-ray fluorescence determination of zinc (in terms of zinc sulfate) in an acidic zinc plating electrolyte is proposed. The study was carried out using an ARL Quant’X energy dispersive spectrometer (Thermo Fisher Scientific, USA) with a semiconductor silicon-lithium detector. The features of the spectrometer design are presented. The optimal parameters of excitation and detection of zinc radiation were specified when the electrolyte sample was diluted 1:1000. The ZnKα1 line was used as an analytical line. The plotted calibration graph is linear, the correlation coefficient being 0.999234. The results of zinc determination according to the developed method were compared with the data of the reference method of complexometric titration to prove the reliability of the procedure. The results are characterized by good convergence and accuracy. The proposed method of X-ray fluorescence zinc determination in a zinc plating electrolyte equals complexometric titration in the limiting capabilities and even exceeds the latter in terms of the simplicity of sample preparation and rapidity. The developed method of X-ray fluorescence determination of zinc is implemented in analysis of the electrolyte used in the continuous galvanizing unit at «METSERVIS LLC».
Damage accumulation near a hole under low cycle fatigue proceeding from measurements of local deformation response

Published: October 2020

A new destructive method for quantitative determination of the damage accumulation in the vicinity of a stress concentrator has been proposed and verified. Increase of damage degree in local area with a high level of the strain gradient was achieved through preliminary low-cycle pull-push loading of plane specimens with central open holes. The above procedure is performed for three programs at the same stress range (333.3 MPa) and different stress ratio values 0.33, – 0.66 and – 1.0, and vice versa for two programs at the same stress ratio – 0.33 and different stress range 333.3 and 233.3 MPa. This process offers a set of the objects to be considered with different degree of accumulated fatigue damages. The key point of the developed approach consists in the fact that plane specimens with open holes are tested under real operation conditions without a preliminary notching of the specimen initiating the fatigue crack growth. The measured parameters necessary for a quantitative description of the damage accumulation process were obtained by removing the local volume of the material in the form of a sequence of narrow notches at a constant level of external tensile stress. External load can be considered an amplifier enhancing a useful signal responsible for revealing the material damage. The notch is intended for assessing the level of fatigue damage, just as probe holes are used to release residual stress energy in the hole drilling method. Measurements of the deformation response caused by local removing of the material are carried out by electronic speckle-pattern interferometry at different stages of low-cycle fatigue. The transition from measured in-plane displacements to the values of the stress intensity factor (SIF) and the T-stress was carried out on the basis of the relations of linear fracture mechanics. It was shown that the normalized dependences of the stress intensity factor on the durability percentage for the first notch (constructed for four programs of cyclic loading with different parameters), reflect the effect of the stress ratio and stress range of the loading cycle on the rate of damage accumulation. The data were used to obtain the explicit form of the damage accumulation function that quantitatively describes damage accumulation process. The functions were constructed for different stress ratios and stress ranges.

Authors: Vicen Martin , Bokůvka Otakar , Nikolić Ružica , Bronček Jozef
Published: October 2020

The tribological properties of the nitride layer applied to the low-alloyed steel were investigated in this research. Experimental work included determination if the chemical composition, wear resistance, Rockwell, Vickers and nano-indentation tests, both of the substrate material – the low-alloyed steel and the deposited nitride layer. From the results obtained in those experiments authors concluded that applying the nitride layer does not significantly improve the tribological properties of the tested lowalloyed steel samples, thus this process is not recommended for achieving that purpose.

Published: October 2020

In the past, it was enough for the airport to have a runway and a modest terminal. The development of air traffic has also increased customer requirements (passengers, airlines, etc.), which has affected the need for airport infrastructure development. Throughout the world, passenger terminals have been built, many of which, according to architectural solutions, represent works of art. The design and functionality are tailored in such a way as to enable longer stay and meet the requirements of passengers and other users. Content and concept offer solutions that airport operators provide for additional revenue. One part of the content and service is offered in passenger terminal buildings, while the other part is provided outside them, whether in or outside the airport. Part of this content is offered by Airport City (AC). AC phenomenon represents the integration of infrastructure, superstructures, information and operations. It represents a part of the Supply Chain (SC) and usually includes facilities such as: passenger terminals, runways and other airport activities such as: ground handling, logistics, office space, shops, hotels, etc. In this paper, authors use a method of systems theory, a modeling method and a comparative method as a general and some specific scientific methods of cognition, to researching the problem to which different AC models and their structure can contribute to the optimal SC flow as its essential part and bring the results of the AC phenomenon as a part of the SC.
The Effect of Gradation and Grain-Size Properties of Fine Aggregate on the Building Mortars
Authors: Mehmetoğulları Ebubekir , Güneyli Hakan , Karahan Süleyman
Published: October 2020

This work is about the effect of fine aggregate properties on the physicomechanical characteristics of hardened mortars. The results indicated that the increase in grain-size of fine aggregate increases the bulk density of hardened mortars. The strength of mortars including limestone fine aggregate is higher than that of the silica-sand. Regardless of the aggregate origin, the strength of the mortars with well-graded fine aggregate for all grain-size is greater than of with uniform fine aggregate. This indicates that grading of fine aggregate increases the strength, while uniformity decreases it.

The strength of mortars with well-graded fine aggregate increases as the grain-size increases. Regardless of the aggregate origin, the strength of mortars with uniform fine aggregate increases with increasing grain-size until the grain-size range of 425-1000 µm, but after this range it decreases with increasing grain-size. The thermal conductivity increases with the increase in the grain-size. Notedly, the relationship between thermal conductivity and maximum grain-size of well-graded fine aggregate has a very strong positive correlation. Further, the thermal conductivity value for mortars formed with uniform fine limestone aggregate is minimum at the grain-size range of 425-1000 µm, while it has greatest values close together from this grain-size range

Authors: Tikhonova O. A. , Gavrilova O. A. , Radchenko E. A. , Verzhuk V. G. , Pavlov A. V.
Published: October 2020

Background.Learning about morphological and biological features of pollen is very important to make correct estimations of plant productivity and breeding efficiency.

Materials and methods. The viability of black currant pollen was analyzed in 2019 at the Laboratory for Long-Term Storage of Plant Genetic Resources, N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR). Eleven black currant cultivars of various ecogeographic and genetic origin maintained at Pushkin and Pavlovsk Laboratories of VIR served as the material for the research. Pollen viability was tested on an artificial medium with 10% sucrose and 0.8% agar. Morphological studies were carried out using light and confocal laser scanning microscopy at the Palynology Laboratory and the Core Centrum of Cell and Molecular Technologies in Plant Science housed by the Komarov Botanical Institute (BIN).

Results and conclusion. The prevailing adverse weather conditions in 2019 produced a negative impact on the process of male generative structure formation. The level of pollen viability, depending on the cultivar, ranged from 17.98 to 58.60%. After exposure to liquid nitrogen (–196°C) for 6 months, the number of germinated pollen grains increased 1.1 to 3.2 times in all the studied cultivars, except one (‘Pozdnyaya poslevoennaya’, k-7652). A palynomorphological study revealed that reduced pollen viability in some cultivars (‘Krasnoyarskaya 1018’, k-7607; ‘Tsema’, k-25900; ‘Pozdnyaya poslevoennaya’, k-7652) was associated with morphological deviations in the sporoderm structure (small pollen grains, exine thickening and formation of verrucate mesoporium surfaces). A low positive correlation was observed between the level of pollen viability and the diameters of the pore (r = 0.43) and pollen grain (r = 0.27). An insignificant negative correlation was apparent between the level of viability and the exine thickness (r = –0.33).
Molecular genetic characteristics of broccoli (Brassica oleracea L. var. italica Plenck) from the VIR collection
Authors: Fateev D. A. , Artemyeva A. M.
Published: October 2020

Background. Broccoli is an early-ripening vegetable crop that contains many biologically active compounds and mineral elements. According to the Genesys database, the global genebank collections contain no more than 465 different broccoli accessions. Fourteen cultivars and hybrids developed in Russia are registered in the State Register of the Russian Federation. The need to improve the assortment in a number of important breeding target areas (small habitus, non-spawning, bud size, disease resistance, etc.) requires the use of new effective techniques, including marker-assisted selection methods and association mapping. In this regard, it seems relevant to evaluate the VIR collection of broccoli using molecular genetic markers, which will provide new source material for breeding.

Materials and methods. A molecular genetic study involved 39 broccoli cultivars and hybrid populations of different geographical origin, with various biological characteristics, and for various uses. For the analysis, 35 markers of microsatellite sequences specific to the Brassica L. genome were selected. PCR products were separated by electrophoresis on a 3% agarose gel.

Results and conclusions. As a result, 110 polymorphic fragments were identified. In the studied loci, 3 to 7 alleles were pinpointed. The discriminating power of markers ranged from 0.75 to 0.96, and averaged 0.91; the average number of fragments per marker was 4.4. Ten unique alleles and 12 rare alleles (found in less than 8% of the samples) were observed in the studied accessions. On the other hand, the 201 bp allele of the locus BC65 was found in 95% of accessions, that is, it was almost common. All used markers have a sufficiently high diagnostic value and can be recommended for DNA identification in broccoli cultivars. An analysis of the genetic similarity of the collection accessions, carried out in the DarWin program using the Unweighted Neighbor-Joining method, made it possible to establish four closely related clusters.

Authors: Pereira-Graterol Freddy , Salazar-Marcano Francisco , Venales-Barrios Yajaira
Published: October 2020

El síndrome de Mirizzi puede cursar con manifestaciones clínicas y hallazgos imagenológicos y de laboratorio, similares a los encontrados en las neoplasias biliares malignas.

Se describe el caso de un paciente cuyo enfoque clínico inicial y estudios de imágenes aportaron datos sugerentes de neoplasia de las vías biliares. Los marcadores tumorales (CA 19-9, CEA) resultaron elevados. Una nueva evaluación clínica y la exploración endoscópica por laparotomía de las vías biliares, permitieron establecer el diagnóstico de síndrome de Mirizzi. Después de la extracción del cálculo biliar y de la anastomosis entre el conducto hepático y el yeyuno, el paciente permaneció asintomático. En este caso, la reevaluación clínica y el uso del protocolo adecuado de estudio, contribuyeron a orientar y confirmar el diagnóstico de síndrome de Mirizzi, lo cual determinó la conducta terapéutica más acertada.

Published: October 2020

Introducción. La colecistectomía laparoscópica es el tratamiento estándar para la colecistitis aguda. En pacientes con coledocolitiasis, la colangiopancreatografía retrógrada endoscópica es el tratamiento de elección. Se ha reportado que, después de este procedimiento endoscópico, la colecistectomía laparoscópica es más difícil y son mayores las tasas de conversión, hemorragia y tiempo operatorio. El objetivo de este estudio fue determinar si en nuestro medio las colecistectomías laparoscópicas posteriores a este procedimiento endoscópico presentan más complicaciones posquirúrgicas y mayor dificultad técnica. Métodos. Estudio de cohorte prospectivo, en el que se comparó un grupo de pacientes sometidos a colecistectomía laparoscópica previa colangiopancreatografía retrógrada endoscópica, contra un grupo homogéneo de pacientes sin colangiografía previa, para evaluar la dificultad en la colecistectomía laparoscópica, la conversión, la reintervención y las complicaciones. Resultados. El 45,4 % de las cirugías fueron difíciles. No hay relación entre la realización previa de colangiopancreatografía retrógrada endoscópica y la dificultad de la colecistectomía laparoscópica. Con el modelo de regresión logística, se encontraron como factores predictores para una cirugía difícil, la edad, el sexo masculino, la cirugía abdominal previa, la colecistitis aguda y la mayor gravedad de la colecistitis aguda.  Conclusión. La colangiopancreatografía retrógrada endoscópica en nuestro medio no constituye un factor de riesgo para dificultad en la colecistectomía laparoscópica. Debe prestarse especial cuidado al sexo masculino, la gravedad de la colecistitis aguda, los antecedentes de cirugía abdominal y la presencia de comorbilidades a la hora de planear una colecistectomía laparoscópica, tomando precauciones adicionales en estos casos para prevenir complicaciones.

H63D CG genotype of HFE is associated with increased risk of sporadic amyotrophic lateral sclerosis in a single population
Authors: Zhang Qing-Qing , Jiang Hong , Li Chun-Yan , Liu Ya-Ling , Tian Xin-Ying
Published: October 2020

This paper describes the genetic etiology of sporadic amyotrophic lateral sclerosis in a single population. Polymerase chain reaction-restriction fragment length polymorphism and DNA sample sequencing of 3 common HFE gene variants (C282Y and H63D and S65C) were performed on 10 randomly selected samples of H63D gene variant (124 patients with sporadic amyotrophic lateral sclerosis) and 10 wild types of H63D samples (210 controls). The C282Y and S65C gene variant were absent. There were 24 cases (7.18%) with H63D heterozygous variants, including 16 cases (13%) in the sporadic amyotrophic lateral sclerosis group and 8 cases (4%) in the healthy control group. The polymorphism frequency of the H63D gene variant in the sporadic amyotrophic lateral sclerosis group was significantly different than that in the control group (p < 0.05), and the difference at allele level, which is still more significant (p < 0.05). H63D gene variant could be a risk factor for sporadic amyotrophic lateral sclerosis in a single population. The results showed HFE gene variants play a role in the occurrence of sporadic amyotrophic lateral sclerosis, but its effect should be carefully estimated.

MicroRNAs are reportedly involved in the pathogenesis of neurodegenerative diseases, including Parkinson’s disease and multiple system atrophy. We previously identified 7 differentially expressed microRNAs in Parkinson’s disease patients and control sera (miR-30c, miR-31, miR-141, miR-146b-5p, miR-181c, miR-214, and miR-193a-3p). To investigate the expression levels of the 7 serum microRNAs in Parkinson’s disease and multiple system atrophy, 23 early Parkinson’s disease patients (who did not take any anti- Parkinson’s disease drugs), 23 multiple system atrophy patients, and 24 normal controls were recruited at outpatient visits in this study. The expression levels of the 7 microRNAs in serum were detected using quantitative real-time polymerase chain reaction. A receiver operating characteristic curve was used to evaluate whether microRNAs can differentially diagnose Parkinson’s disease and multiple system atrophy. Clinical scales were used to analyze the correlations between serum microRNAs and clinical features. The results indicated that miR-214 could distinguish Parkinson’s disease from the controls, and another 3 microRNAs could differentiate multiple system atrophy from the controls (miR-141, miR-193a-3p, and miR-30c). The expression of miR-31, miR-141, miR-181c, miR-193a-3p, and miR-214 were lower in multiple system atrophy than in Parkinson’s disease (all P < 0.05). Combinations of microRNAs accurately discriminated Parkinson’s disease from multiple system atrophy (area under the receiver operating characteristic curve = 0.951). For the correlation analysis, negative correlations were discovered between the expression of miR-214 and the Hamilton Anxiety Scale and Parkinson’s Disease Non-Motor Symptom scores (all P < 0.05). Our results demonstrate that the distinctive characteristics of microRNAs differentiate Parkinson’s disease and multiple system atrophy patients from healthy controls and may be used for the early diagnosis of Parkinson’s disease and multiple system atrophy.

Published: October 2020

Anomalies in the ST segment, especially ST-segment elevation, require the ruling out of possible etiologies such as myocardial ischemia or pericarditis. However, other non-cardiac disorders such as increases in intra-abdominal and intrathoracic pressure, may cause ST-segment elevation as well and should be considered as possible etiologies due to the poor prognosis they imply in the clinical evolution of the patient. This is especially important in critically ill patients. In this respect, we herein present a case in which the increase in intra-abdominal pressure and thoracic cavity elevation due to gastric and intestinal distension, which was not present in the first CT, provoked a cardiac and coronary compression resulting in T-shaped dome wave, a QT prolongation and ST segment elevation in the inferior leads of the electrocardiogram, the patient did not present at the time of admission, ruling out other possible etiologies such as ionic imbalance or acute ischemia.
Enoxaparin related spontaneous fatal retroperitoneal hemorrhage in a patient with atrial fibrillation
Authors: Oh Tak-Hyuk , Jung Hanna , Lee Youngok
Published: October 2020

Spontaneous retroperitoneal hemorrhage (SRH) is a potentially lethal complication of anticoagulation therapy. The signs and symptoms vary from clinical silence to abdominal pain or hemorrhagic shock. The diagnosis of SRH may be difficult, especially in its early clinical course, due to its varied symptoms. Physicians need to have a high degree of suspicion for its early diagnosis. Delayed diagnosis of SRH can lead to serious complications or death. Bleeding complications in anticoagulated patients are well known; however, reports about SRH with fatal outcomes are sporadic. Here, we describe a case of massive SRH in a patient receiving enoxaparin. In our case, the patient died due to delayed diagnosis and treatment. We, therefore, emphasize that physicians should always consider SRH in any patient receiving anticoagulants who presents with abdominal pain.

Published: October 2020

Atrial fibrillation (AF) is the most common arrhythmia among the elderly, and more frequently occur in those with chronic kidney disease (CKD). Left atrial appendage occlusion (LAAO) is used as a mechanical alternative approach for prevention of AF-related thromboembolisms. This meta-analysis was conducted to provide suggestions for the clinical application of LAAO in AF patients with CKD. The incidence of perioperative adverse events and other clinical effects after operation was by a single rate meta-analysis. Results showed that incidence of adverse events in the perioperative period after LAAO was generally low, with only pericardial effusion / tamponade (1.90%) and mortality rate (1.10%). During the follow-up period, the incidence of stroke/transient ischemic attack (TIA) and bleeding were 2.17% and 4.53%, respectively. A low incidence rate of adverse events was found in the perioperative period following LAAO. These results indicate that LAAO more effectively prevents the occurrence of stroke/TIA and minimizes bleeding events than oral anticoagulants.
Relationship between cardio-ankle vascular index and obstructive sleep apnea
Authors: Tomita Yasuhiro , Kasai Takatoshi
Published: October 2020

Patients with obstructive sleep apnea (OSA) are susceptible to developing atherosclerosis. Consequently, such patients are at a high risk of developing cardiovascular diseases, leading to poor prognosis. Many physiological parameters have been previously used to predict the development of atherosclerosis. One such parameter, the cardio-ankle vascular index (CAVI), a measure of arterial stiffness, has garnered much attention as it can also predict the degree of atherosclerosis. The CAVI can be calculated based on noninvasive measurements, and is less susceptible to blood pressure variations at the time of measurement. Therefore, the CAVI can assess changes in arterial stiffness and the risk of developing atherosclerosis independent of blood pressure changes. Continuous positive airway pressure (CPAP) is a standard therapy for OSA and can suppress the issue significantly. Several studies have shown that CPAP treatment for OSA could also reduce the CAVI. In this review, we discuss the relationship between OSA and arterial stiffness, primarily focusing on the CAVI. Furthermore, we propose future perspectives for the CAVI and OSA.

Wirausaha seni, khususnya di bidang seni pertunjukan, menjadi hal penting dalam kaitan dengan perkembangan ekonomi dan industri kreatif. Bidang ini mendapat perhatian khusus dari pemerintan dalam 4 tahun belakangan, dengan dibentuknya sebuah badan khusus, BEKRAF. Mengembangkan wirausaha seni di antaranya dapat dilakukan melalui festival. Tulisan ini mengambil studi kasus Bandung Isola Performing Arts Festival (BIPAF) yang telah meletakkan dasar wirausaha seni sejak tahun 2016. Dengan menggunakan metode kualitatif melalui pendekatan teori social enterpreneurship, penelitian ini menghasilkan sejumlah rumusan bahwa (1) BIPAF telah menawarkan sebuah model pengembangan wirausaha seni dengan model pasar seni pertunjukan (performing arts market) yang menggunakan site specific stage, yakni Villa Isola UPI Bandung, untuk mempromosikan bentuk karya tari dan atau teater tari inovatif berbasis tradisi dan kolaborasi, serta mempertemukan para kreator dengan stakeholdernya, sekaligus berperan dalam pelestarian seni budaya; (2) untuk menjaga kualitas karya yang dihasilkan, karya-karya yang ditampilkan di BIPAF melalui sejumlah tahapan seleksi dan kurasi, inkubasi, pertunjukan hingga evaluasi. Indikator keberhasilan program ini di antaranya terlihat pada meningkatkan kuantitas pementasan para pentolan BIPAF yang dikelola secara profesional oleh para pengelola event, baik di dalam maupun di luar negeri.
The Covid-19 Pandemic and the Rights of the Individual in Terms of Private and Public Law

The principles of adjusting the regulation of civil relations in the context of the Covid-19 pandemic are analyzed. The admissibility of restricting human rights in the context of the conflict of private and public interests are researched. Besides, the authors tried to determine the optimal algorithm of government actions aimed at preventing the spread of the epidemic. The main approach to the understanding of human rights in the article is based on Dworkin's concept of “rights as trumps”. A system of such categories as “a man”, “a private person”, “natural private rights”, “private law” and “national civil law” is analyzed. The conclusion is that the importance of the category of “natural” human rights is underestimated, which exacerbates the problem of ensuring human rights in a pandemic, when the state actively uses public law to cope with the crisis. As a result, there is a conflict of basic principles of private and public law: “everything is allowed except what is prohibited by law” vs. “only what is allowed by law is possible”. It is proposed to assume that the usual way of the legal existence of a person is that he/she acts as a participant in civil relations of a private type, even in a pandemic. Private relations, which arise during the quarantine period, are proposed to be regulated mainly by private law methods, limiting the influence of the state. This will allow us to reach a compromise of private and public interests, without restricting the rights of individuals voluntarily.

Purpose. A social gradient in adolescent mental health exists: adolescents with higher so-cioeconomic status (SES) have fewer mental health problems than their peers with lower SES. Little is known about whether adolescents’ societal beliefs play a role in this social gradient. Belief in a just world (BJW) may be a mediator or moderator of the social gradient in adolescent mental health.Methods. Using data from 1,130 adolescents (Mage = 17) in the Netherlands, path analyses examined whether two indicators of BJW (general and personal) mediated or moderated the associations between two indicators of SES (family affluence and perceived family wealth), and four indicators of adolescent mental health problems (emotional symptoms, conduct problems, hyperactivity and peer problems).Results. Adolescents with lower perceived family wealth reported more emotional symp-toms and peer problems, and these associations were partly mediated by lower personal and general BJW. Furthermore, higher personal BJW amplified the negative association be-tween SES and peer problems.Conclusion. This study suggests BJW may both mediate and amplify the social gradient in adolescent mental health. Adolescents’ beliefs about society may be important to include in research aimed at understanding this social gradient.
Differential expression of topoisomerase IIα in cancers of the breast.

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We identified significant differential expression of the gene encoding the DNA topoisomerase IIα, TOP2A, when comparing primary tumors of the breast to the tissue of origin, the normal breast. Expression of TOP2A in primary tumors of the breast was significantly higher than in normal breast tissue, and patients with low expression of TOP2A in primary tumors had markedly superior overall and relapse-free survival. TOP2A may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Sap from various species palm trees in which known as neera generally produced by traditional technology in Indonesia. There are 5 well known palm species that produce Neera in Indonesia such as arenga palm, coconut tree, doub palm, nipa palm and palm oil. Neera can be utilized as raw material for various derivatives such as palm sugar, sweet palm toddy, and alcoholic toddy. Tapping of neera is a crucial step because neera prone to immediately degrade and causing poor quality of palm sugar. Traditional sugar processing has some drawbacks for example: low energy efficiency processing and off-specification products. On the other side, sugar palm neera has important antioxidant component which benefits for human that unavailable in normal white sugar from sugarcane. In this current review, characterization of neera from various palms in Indonesia and available technology on sugar palm processing such as spray dryer and membrane ultrafiltration will be discussed.

Suara menjadi komponen terpenting dalam perkembangan teknologi digital saat ini, untuk mempermudah kehidupan manusia. Berbagai sistem pengenalan suara atau Automatic Speech Recognation (ASR) telah banyak dikembangkan di berbagai negara dengan berbagai bahasa. Pengenalan suara dapat diaplikasikan di berbagai bidang kehidupan salah satunya pada sistem keamanan berbasis suara, berupa password. Di Indonesia sendiri banyak penelitian mengenai pengenalan suara menggunakan bahasa Indonesia dengan berbagai metode, tetapi masih dalam jumlah yang terbatas dan hanya berfungsi untuk perintah suatu aplikasi tertentu. Oleh karena itu, pada penelitian ini, penulis melakukan pengenalan suara berdasarkan suku kata bahasa Indonesia karena bahasa Indonesia sendiri memiliki suku kata yang terbilang banyak dibandingkan dengan suku kata bahasa asing lainnya. Sistem ini terdiri dari 4 proses yaitu proses perekaman suara, proses pre-processing, proses ekstraksi ciri menggunakan metode Linier Predictive Code (LPC), dan proses klasifikasi suara menggunakan metode Backpropagation Neural Network. Terdapat 115 suku kata dan 74 suku kata yang berbeda dari 50 kata bahasa Indonesia yang diucapkan. Total suku kata bahasa Indonesia yang digunakan berjumlah 690 suku kata dari 6 responden. Hasil akurasi pada sistem pengenalan suku kata bahasa Indonesia yaitu 100% mampu mengenali 74 data pelatihan dari setiap 6 responden dan 115 data pengujian belum dilatih didapatkan akurasi terbaik sebesar 69% dari 6 responden. Berdasarkan hasil pengujian yang telah dilakukan, semakin banyak data pelatihan yang diproses dalam jaringan maka semakin tinggi akurasi keberhasilan yang diperoleh (Sinyal suara dapat dikenali).

Statins are the integral medications for the management of patients with acute coronary syndrome including unstable angina (UA) with multiple pleiotropic effects. However, the influence of statins on the coagulation system is controversial. Our study aimed to explore the effects of atorvastatin and rosuvastatin in high doses on some coagulation parameters (prothrombin pool (PP) and soluble fibrin-monomer complexes (SFMC) concentration) after a 7-days follow-up period in patients with UA. We recruited 50 patients aged 55 to 70 years with progressive UA. Standard therapy according to ESC guidelines 2020 was recommended for all patients. Before treatment onset, they were divided into 2 groups: group A – 26 patients were prescribed atorvastatin, group R – 24 patients with rosuvastatin treatment. The blood samples to analyze the concentration of PP and SFMC were collected twice – before the treatment onset and 7 days after. We revealed significant decrease in PP concentration (p=0,02) and increase in SFMC concentration (p=0,01) in group A patients while there were no significant changes of investigated parameters (p=0,94, p=0,57 respectively) in group R. Additionally, we have noted significant negative correlation between baseline PP concentration and direction of PP changes (r=-0,803, p<0,001) as well as PP changes direction and SFMC concentration after treatment (r=-0,655, p<0,001). Thus, we may consider that atorvastatin and rosuvastatin are characterized by different influences on coagulation in patients with progressive UA with standard basic treatment. The rebound coagulation system activation after anticoagulant discontinuation is more pronounced in UA patients against a background of atorvastatin treatment in comparison with rosuvastatin.
