STYLISTIC TERMINOLOGY IN THE WORKS OF LINGUISTS OF THE KHARKIV PHILOLOGICAL SCHOOL ІN THE 20S–30S OF THE 20TH CENTURY
Authors: СHEREMSKA Olga
Published: May 2023

The article systematizes and analyzes the stylistic terminology presented in scientific studies, works on language culture, stylistics, and translation studies by representatives of the Kharkiv Philological School of the 20s-30s of the 20th century. Cross-cutting theoretical and practical issues related to the development of the terminological tools of Ukrainian linguistic stylistics during the period of its formation as a separate branch of linguistics are traced. The relevant stylistic categories relied on by researchers of the language and style of Ukrainian classical writers, the language of science and journalism are noted: modern literary language, living language, folk language, sense of language, linguistic taste, peculiarities of the Ukrainian language, scientific language, artistic language, language of the press, literary norm, literary form, verbal formulas, linguistic phenomenon, specific meaning, context, synonyms, construction not characteristic of the Ukrainian language, uzus. Emphasis is placed on the fact that in the works of M. Sumtsov, O. Kurylo, O. Sinyavskyi, M. Hladkyi, M. Sulima, M. Johansen, S. Smerechynskyi, L. Bulakhovskyi, B. Tkachenko, O. Finkel, the terms and facts of the language in the broad context of other languages, with the involvement of foreign language counterparts. Underscored the advantage of studying stylistic means in practical terms as an additional characteristic of lexical, phraseological, grammatical phenomena, as a means of diversification, development of general literary norms. The characteristic features of this period are noted: 1) the instability of terminology, 2) the presence of variants in the terminological system of stylistics, 3) the consistent use of the lexemes language and language in term compounds. Substantial achievements of scientists were the justification of stylistics as a separate educational discipline, the definition of the main concepts of stylistics, the systematization of linguistic phenomena according to separate functional styles and according to the carriers of the corresponding linguistic properties; formulation of practical advice on the use of lexical groups, phraseological units, grammatical forms; analysis of idiosyncratic features of Ukrainian literary classics. The study of a specific terminological system in diachrony outlines the trends in the development of linguistic terminology in general.
A Computational Technique for Low-Cycle Fatigue of LNG Mixing-Tee Weldment – An Industry Case Study
Authors: Abdul Matin Al-Barr Malek  , Abdul Rahim Othman  , Muhammad Firdaus Othman
Published: May 2023

This research describes a computational method for low-cycle fatigue cracks in LNG mixing-tee weldments. Using a combination of thorough finite element modelling and fatigue life prediction with the finite element software ABAQUS and FE-Safe, the approach is able to simulate the thermal stresses and fatigue damage of a mixing-tee subjected to thermal cycle. The approach consists of three primary phases. First, the thermal distribution at the mixing-tee junction caused by the mixing temperature of the liquefied natural gas (LNG) is predicted. These first-step solutions are then included into second-step modelling, which simulates the thermal stress of the mixing-tee. The next phase entails modelling the fatigue behaviour of the mixing-tee using the thermal stress data. The computed fatigue life cycle achieves a 92.8% accuracy level when compared to real on-site observations. The suggested method enables the accurate prediction of thermal and fatigue behaviours within a tolerable computational time.

Published: May 2023

Mesoscale–combustor is one component of the micropower generator. The mesoscale–combustor function is to produce heat energy from the combustion of chemical hydrocarbon compounds. The small dimensions of the meso-combustor cause large losses and short residence times for the reactants. These two factors lead to narrow flame flammability limits. This study aims to increase flammability limits by lengthening the reactant residence time and increasing reactant mixing with inserts of flow retardants called flame holders. There are two kinds of flame holders used in this study, namely holes and lines. Lines type produces flames at an equivalent ratio of Φ0.83–1.76 and speeds of 17.01 cm/s to 72.93 cm/s, while holes type produces flames at an equivalent ratio of Φ0.91–1.71 and a flow rate of 24.94 cm/s to 54.95 cm/s. This phenomenon shows that the line type flame holder is able to inhibit flow better and form vortices better, thereby increasing heat recirculation, flame stability, and widening flammability limits.

Published: May 2023

Flows in a microfluidic environment differ in their flow parameter changes compared to macro flows and should be handled carefully. Recently microfluidic innovations have been drawn into much consideration in biomedical, chemical synthesis, and cooling industries. There exists a need for a flow rate sensor for measuring tiny fluid flows in developing microfluidic Lab-on-chip products, Organ-on-chip, and other products for biological, chemical, and other flow analysis. Working with microfluidic products mainly revolves around flow measurement. The control of these frameworks is just conceivable with sensors that estimate flow rate. In this work, we understand the dynamics of microfluidic flow and try to determine its influence on sensor behavior. The paper presents the construction of flow-sensing techniques for microflows. The design of the microchannel opted for the study is also discussed. A microfluidic flow rate sensing technique is put forward using the physical principle of fluid dynamics; based on pressure in a rectangular microchannel. For rectangular microchannel, the variation in pressure had an impact on the flow rate measurement of the microflow sensor.

Published: May 2023

In current communication, the thin-film flow of Casson hybrid nanofluid consists of copper and alumina nanoparticles that dissolved in carboxymethyl cellulose (CMC) plus water over an unsteady stretching porous sheet is elucidated. Using suitable similarity variables, the resultant partial governing equations are turned into a set of nonlinear ordinary differential equations. The Keller box approach is then used to solve the transformed equations. The unknown thin-film thickness constant is determined by using the homotopy analysis approach. The thermal and velocity distributions, as well as the Nusselt number and skin friction of the fluid, are discussed for different values of relevant parameters such as thin-film thickness, nanoparticles volume fraction, and mass transition parameter. The distributions of temperature and velocity decrease when the thin-film thickness is increased. The velocity distribution is decreased by the Casson, nanoparticles volume fraction, and mass transition (injection) parameter. The temperature is enhanced by the nanoparticle's volume fraction and the Casson parameter, however, has an opposite tendency with the mass transition (injection) parameter. For the physical quantities, the skin friction has a negative function with all the parameters. The mass transition (injection) parameter increases the Nusselt number. The outcomes of the present study are useful for example in producing the smart contact lens that has been used in the biomedical field.

Published: May 2023

In modern applied mathematics, engineering, and the physiological world, the concept of peristalsis is of great significance. The present article concentrates on the peristaltic movement of Carreau-Yasuda fluid through planner micro-channel under the influence of applied magnetic field and partial slip conditions. The governing system of equations are nondimensionalized and transformed using basic assumptions such as long wavelength and low Reynolds number. A bulti-in route "ND solve" in Mathematica exercised to solve obtained nonlinear coupled equations with appropriate boundary conditions. Obtained results are elucidated by plotting graphs for different physiological constraints such as velocity, temperature, and concentration. Physical characteristics such as skin friction, Nusselt number and Sherwood number are discussed via table results. The typical character of this work e.g. flow index parameter exhibits that the apparent fluid viscosity becomes high when it has a higher value due to which fluid faces more resistance and the presence of a higher magnetic effect predicts the decreasing behavior on velocity. Additionally, the trapping phenomenon explains bolus movement and are discussed briefly.
TD 2876 - Trajetória recente e características regionais do consumo de energia elétrica para famílias de baixa renda no Brasil a partir dos dados do programa TSEE (2014-2021)
Authors: Silva Filho Edison Benedito da , Homsy Guilherme Vampré
Published: May 2023

Este estudo analisa a trajetória recente e as características regionais do consumo de energia elétrica entre as famílias de baixa renda no Brasil, utilizando dados de beneficiários do programa Tarifa Social de Energia Elétrica (TSEE). Busca-se avaliar os impactos das medidas restritivas e mudanças regulatórias implementadas ao longo de 2020 para contenção da pandemia sobre o comportamento dos consumidores residenciais de energia elétrica no Brasil. O trabalho apresenta uma nova metodologia para avaliação dos impactos econômicos da TSEE a partir do detalhamento dos dados do programa em nível regional, bem como da simulação de variações no consumo de energia elétrica dos beneficiários do programa em resposta a mudanças no preço do serviço público ofertado. Encontraram-se evidências de que a elevação de custos no fornecimento de energia elétrica no período recente (notadamente, a partir de 2014) produziu efeitos negativos significativos e diferenciados para as regiões do país, ampliando as desigualdades no acesso à energia elétrica e na quantidade consumida pelos domicílios de baixa renda do país. Por sua vez, as medidas de auxílio financeiro do governo federal às famílias de baixa renda no período considerado mais crítico para o enfrentamento da pandemia de covid-19, no segundo semestre de 2020, não parecem ter produzido grandes impactos em termos de alteração do seu padrão de consumo de energia, assim como nas discrepâncias regionais já observadas no mercado consumidor de baixa renda no Brasil.
Does overproduction of chaperone proteins favour the repair of DNA injuries induced by oxidative stress? (Mini review)
Authors: Chankova Stephka G. , Yurina Nadezhda P. , Todorova Teodora I. , Parvanova Petya N.
Published: May 2023

Genotype resistance to oxidative stress, induced by various physical/chemical stimuli has been the focus of scientists for the last decades, with several aspects – ecological (the formation of the genetic elite of population), agricultural and medical (radio-chemotherapy).

Genotype resistance to oxidative stress is regarded as the integration of different morphological, physiological, biochemical, metabolic and genetic characteristics. Currently, it is supposed that the mechanisms involved in the formation of genotype resistance to oxidative stress are inter-correlated and inter-dependent, comprising changes in genes, proteins, enzymes, different metabolic pathways and/or biological networks. According to the present state of knowledge, various cellular targets, resulting in genotoxic stress, induction of DNA damage, mutations, genomic instability or apoptosis can trigger different signal transduction pathways, activating DNA repair, antioxidant and chaperone defence systems.

Till now, a lot of experimental data have been accumulated concerning the contribution of DNA repair to the formation of genotype resistance to oxidative stress. At the same time, genotype resistance of organisms is largely determined by the ability of molecular chaperones to maintain conformational homeostasis of proteins (folding – misfolding – refolding or aggregation – degradation). The role of chaperones in protein homeostasis and cell death, especially in apoptosis, is well discussed in literature, but much less is known about their function in DNA repair. In this regard, here we addressed the question of whether the overproduction of chaperone proteins contributes to the repair of DNA damage caused by oxidative stress.

Published: May 2023

The incidence of consumption on Facebook around the world and its implications for university students is something that has necessarily been studied in the scientific literature (Gil et al., 2019). Fewer and far between are works focused on the study of social networks and academic procrastination in a population, particularly with a non-traditional teaching methodology (General Studies), even though this knowledge would allow us to obtain a profile of university students and identify their possible actions that could derive in academic problems. As a matter of fact, its importance has enabled the present study to analyze the relationship between the motivations for using Facebook and academic procrastination, and consequently determine the resulting correlation with certain indicators of use, satisfaction with Facebook and academic procrastination. For this purpose, the Facebook Usage Questionnaire was used (Igartua & Rodríguez de Dios, 2016), in addition to the Academic Procrastination Scale (Domínguez-Lara et al., 2014), with a sample of 150 students in their first year at a public university. In this manner, the results agree, showing a clear relationship between the motivations of “entertainment” and “virtual community” with moderate levels of procrastination, corresponding to greater implication with this social network. Significant differences in terms of gender and age are shown, which allows for a better understanding of the behavior pattern of these variables.
An improved signal detection algorithm for a mining-purposed MIMO-OFDM IoT-based system
Authors: Guo Jikun , Zhao Qing , Guo Lixuan , Guo Shize , Liang Gen
Published: May 2023

The coal mine internet of things (IoT) communication system is used for real-time monitoring of mining production to ensure the safety and reliability of personnel and equipment in the mine. To eliminate multipath fading in the process of wireless communication in mines, multiple-output multiplexing (MIMO) and orthogonal frequency division multiplexing (OFDM) technologies are introduced. In this paper, a wireless communication system architecture of IoT in mining based on MIMO-OFDM is constructed. Aiming to solve the problems of intersymbol interference and frequency selective fading at the receiver, an improved minimum mean square error ordered successive interferences cancellation (MMSE-OSIC) signal detection algorithm is proposed. First, the signal-to-interference plus noise ratio of the received signal is calculated and the calculation results are sorted. The lowest signal-to-noise ratio is selected as the weakest signal layer. Then, the MMSE-OSIC algorithm is used to extract all of the signals, except the weakest layer. Finally, a maximum likelihood (ML) algorithm is used to traverse the whole signal domain; the signal symbol with the smallest distance from the weakest signal layer is found as the original signal of the weakest signal layer, and it is combined with the signal detected by MMSE-OSIC; then, the final signal detection result is obtained. The simulation results show that, compared with three benchmark algorithms, the proposed MMSE-OSIC algorithm has better signal detection performance under the conditions of different modulation methods and different channel numbers.
Kolmogorov variation: KAM with knobs (à la Kolmogorov)
Authors: Sansottera Marco , Danesi Veronica
Published: May 2023

In this paper we reconsider the original Kolmogorov normal form algorithm [26] with a variation on the handling of the frequencies. At difference with respect to the Kolmogorov approach, we do not keep the frequencies fixed along the normalization procedure. Besides, we select the frequencies of the final invariant torus and determine a posteriori the corresponding starting ones. In particular, we replace the classical translation step with a change of the frequencies. The algorithm is based on the original scheme of Kolmogorov, thus exploiting the fast convergence of the Newton-Kantorovich method.
Koga nagovarjajo Shakespearovi soneti (v slovenščini)?
Authors: Zavrl Andrej
Published: May 2023

Shakespearovih 154 sonetov, ki so prvič izšli leta 1609, je literarna veda tradicionalno razvrščala v dve skupini: soneti 1–126 naj bi opevali čednega mladeniča, soneti 127–154 pa »črno damo«. Večinoma je veljalo tudi, da soneti pripovedujejo precej koherentno pripoved o odnosu lirskega subjekta z njima. Besedilna resnica pa je, da je nemogoče reči, koliko oseb Soneti nagovarjajo, poleg tega pa jih je večina spolsko nezaznamovanih. Analize se pri različnih raziskovalkah in raziskovalcih razlikujejo, avtor članka predlaga naslednjo: od 139 sonetov z eno nagovorjeno osebo je v izvirniku 115 spolsko nedoločenih, 14 jih izrecno opeva moškega, 10 pa žensko. Šest sonetov nagovarja dve osebi, preostali pa abstraktne pojme. V slovenščini sta doslej izšla dva integralna prevoda – leta 1965 prevod Janeza Menarta, štiri desetletja pozneje pa Srečka Fišerja – in prevajalca sta se morala soočiti tudi z vprašanjem spolske (ne)določenosti pesemskih besedil ter s fluidnostjo spola in seksualnosti v izhodiščnih besedilih. Oba sta pri obsežnem spolskem razdvoumljanju sledila tradicionalni razporeditvi sonetov v že omenjeni skupini, pri čemer je Fišer nevtralnost ohranil pri nekoliko večjem deležu sonetov kot Menart.

Blockchain is arguably the most disruptive technology of the 21st century. Although most known for its role in cryptocurrency, blockchain is utilized in several innovative ways. For example, an artist's copyright, royalties, and licensing information can be stored using smart contracts, a blockchain-backed technology. This chapter will address the role of blockchain-backed technology throughout the voting process and how state government plans of action may differ as they attempt to regulate and adopt this innovative yet disruptive technology. Additionally, it will compare different e-voting platforms and their underlying frameworks, languages, and consensus protocols. Ultimately, this chapter reveals how electoral practitioners and policymakers have responded to regulating blockchain-backed technologies and how cryptographic framework and technological advancements directly influence the e-voting ecosystem.

To gain insights into the forage morphological and anatomical characteristics in a silvopastoral system (SPS) with Bolsa de Pastor (Zeyheria tuberculosa) and palisadegrass ‘Marandu’ (Urochloa brizantha) monoculture (MONO). The SPS was established through natural regeneration of the tree species. Treatments were a SPS and MONO distributed in a completely randomized design with six replicates and repeated measures were the harvest periods. Response variables were morpho-physiological and anatomical characteristicss: green: dead material ratio, leaf blade: stem+sheath ratio, leaf area index, chlorophyll and carotenoid concentrations, proportions of non-lignified and achlorophyllous areas, lignified areas in stems, proportions of non-lignified and achlorophyllous areas, lignified and chlorophyllous areas in leaves, as well as cell length in longitudinal section of stem. Morpho-physiological patterns were altered (p < 0.05) under natural shading conditions due to higher photosynthetic efficiency in the SPS. There was no effect (p > 0.05) of the systems on anatomical patterns, proportions of non-lignified and achlorophyllous, lignified and chlorophyllous tissues, these proportions were influenced only by the periods of the year, both for stems and leaves. Cells of the internodes of the grasses of the studied systems had the same length. The SPS alters morpho-physiological characteristics of palisadegrass and increases the concentration of chlorophyll a and b.

Period Poverty: A Neglected Public Health Issue
Authors: Jaafar Hafiz , Ismail Suraya Yasmin , Azzeri Amirah
Published: May 2023

Period poverty is a global community health dilemma that has long been overlooked. This condition is described as having insufficient access to menstrual products, education, and sanitation facilities. Briefly, period poverty means that millions of women are subjected to injustice and inequity due to menstruation. This review aimed to explore the definition, challenges, and effects of period poverty on the community, especially among women at their productive ages. In addition, suggestions to minimize the impact of period poverty are discussed. A search strategy was applied using the keywords “period poverty,” “period equity,” “period poverty,” and “menstrual hygiene” in Google Scholar, ScienceDirect, SpringerLink, MEDLINE, and PubMed electronic databases, journals, and articles on relevant topics. Trained researchers conducted a keyword search from January 2021 to June 2022. Based on the reviewed studies, it has been proven that many countries are still affected by the period stigma and taboo, inadequate exposure to menstrual health and its management, lack of education about menstruation, and shortage of access to menstrual products and facilities. The next step is to reduce and slowly eliminate the period poverty issue by conducting more research to increase clinical evidence and future references. This narrative review could inform policymakers of the magnitude of the burden related to this issue and guide them to develop effective strategies to minimize the impact of poverty, especially during the challenging years of the post-coronavirus disease 2019 era.

We also study some related questions on moderate expanders over matrix rings, namely, for
$A, B, C\subseteq GL_2(\mathbb {F}_q)$
, we have
$$\begin{align*}|AB+C|, ~|(A+B)C|\gg q^4,\end{align*}$$

Cost-Effectiveness Analysis of Integrated Bite Case Management and Sustained Dog Vaccination for Rabies Control
Authors: Taylor Emma , Prada Joaquin M. , Del Rio Vilas Victor , Undurraga Eduardo A. , Wallace Ryan , Horton Daniel L.
Published: May 2023

The successful prevention, control, and elimination of dog-mediated rabies is challenging due to insufficient resource availability and inadequate placement. An integrated dog bite case management (IBCM) system plus dog vaccination can help address these challenges. Based on data from the IBCM system in Haiti, we conducted a cost-effectiveness evaluation of a newly established IBCM system plus sustained vaccination and compared it with 1) a no bite-case management (NBCM) and 2) a non–risk-based (NRB) program, where bite victims presenting at a health clinic would receive post-exposure prophylaxis regardless of risk assessment. We also provide cost-effectiveness guidance for an ongoing IBCM system and for sub-optimal dog vaccination coverages, considering that not all cost-effective interventions are affordable. Cost-effectiveness outcomes included average cost per human death averted (USD/death averted) and per life-year gained (LYG). The analysis used a governmental perspective. Considering a sustained 5-year implementation with 70% dog vaccination coverage, IBCM had a lower average cost per death averted (IBCM: $7,528, NBCM: $7,797, NRB: $15,244) and cost per LYG (IBCM: $152, NBCM: $158, NRB: $308) than NBCM and NRB programs. As sensitivity analysis, we estimated cost-effectiveness for alternative scenarios with lower dog-vaccination coverages (30%, 55%) and lower implementation costs. Our results suggest that better health and cost-effectiveness outcomes are achieved with the continued implementation of an IBCM program ($118 per life-year saved) compared with a newly established IBCM program ($152 per life-year saved). Our results suggest that IBCM is more cost-effective than non-integrated programs to eliminate dog-mediated human rabies.
Case Report: Vagal Nerve Neuritis Associated with Pulmonary Melioidosis Provides Potential Insights into the Pathophysiology of Neuromelioidosis
Authors: Matthews Rosie J. , Smith Simon , Wilson Ian , Tjahjono Richard , Young Soon , Hanson Josh
Published: May 2023

Encephalomyelitis is the most frequent manifestation of neuromelioidosis in Australia. It is hypothesized that Burkholderia pseudomallei causes encephalomyelitis after entering the brain directly, if complicating a scalp infection, or after traveling to the brain within peripheral or cranial nerves. A 76-year-old man presented with fever, dysphonia, and hiccups. Chest imaging demonstrated extensive bilateral pneumonia with mediastinal lymphadenopathy, blood cultures isolated B. pseudomallei, and nasendoscopy confirmed a left vocal cord palsy. Magnetic resonance imaging identified no intracranial abnormality but demonstrated an enlarged, enhancing left vagus nerve, consistent with neuritis. We hypothesize that B. pseudomallei invaded the vagus nerve in the thorax, was traveling proximally—involving the left recurrent laryngeal nerve and causing the left vocal cord palsy, but had not yet reached the brainstem. Given the frequency of pneumonia in cases of melioidosis, the vagus nerve may represent an alternative, and indeed common, route for B. pseudomallei to enter the brainstem in cases of melioidosis-related encephalomyelitis.
Roads and Ways of the South of Western Siberia on Russian Maps in the First Half and the Middle of the 18th century
Authors: Zaiceva Lyubov G. , Goncharov Yurij M. , Bobrov Denis S.
Published: May 2023

The development of the Russian periphery was characterized by the flexibility of the imperial strategy of power in the Early Modern period. Cartographic materials were important in influencing the formation of a spatial model of the region. In the frontier and border zones of Siberia and the north of Central Asia, roads and pathways, as well as their graphical representation on maps, served not only a utilitarian function by providing information about movement routes and trajectories, but also influenced the general concept of the territory by acting as markers for political and economic structures and their borders.

This article focuses on the characteristics of the traffic system description of the south of Western Siberia and the cross-border region in Russian cartographic materials from the first half and middle of the 18th century. The territorial scope of the study is limited to the space of the southern regions of the Ob-Irtysh interfluve area, the regions of the Upper Ob and Upper Irtysh, including parts of the Central Asian territories. The authors concluded that among the directions represented in the maps, the Irtysh meridional road stood out during the first third of the 18th century. Since the late 1720s, the north-eastern and northern roads linking the Altai metallurgical complex with the Kuznetsk, Berdsk, and Moscow tract dominated. Special maps appeared by the middle of the 18th century as a result of the increased importance of the Altai road system, recording the development of transport communication in the region.
Buddhist Coast of the Caspian Sea
Authors: Bicheev Baazr A.
Published: May 2023

The article analyzes the pragmatic and textological traditions of the ritual for “neutralizing evil words” in the tantric and folk forms of Kalmykia. The popularity of the ritual in the past and present justifies the focus on this aspect. The study aims to analyze the structure and content of the texts used in performing the tantric ritual and in practicing its popular forms. It employs comparative-historical and textological methods based on the principles of historicism and objectivity. The ritual is a traditional tantric practice that seeks the help of Buddhist deities to remove obstacles to spiritual growth through visualization. The tradition includes two types of texts: tantric sutras and texts of mantras (Dharani). However, most practitioners were not prepared for this level of practice, leading to the development of popular folk forms of protection such as “cutting a black tongue” and other textual traditions. The analysis reveals that the verbal tradition of popular forms is also represented by two types of texts. The popularity of folk forms indicates that Buddhist teachings have long included an organic combination of the tantric ritual and its folk forms.

Frontier Case of the Railroad Technician Luzhanskiy
Authors: Meshcheryakov Alexander Yu.
Published: May 2023

The article analyzes the situation in Southern Manchuria in the Chinese city of Telin in 1901 as a result of the actions of Luzhansky (Luzhanskiy), a railway technician who served in the CER Society. Luzhansky showed direct violence toward indigenous people and Chinese workers during the laying of the track. The established administrative system of administration in the territory of the CER right‑of-way could not resolve the conflict between the Chinese and Russian subjects. Luzhansky's case could have been regulated by the Tianjin Treaty of 1858 and the 1896 treaty for the construction and operation of the railroad, but the railway technician's actions extended beyond Northern Manchuria.

Given that the Luzhansky technician's trial caused a clash of Russian and Chinese jurisdictions, this article examines the formation of the judicial system in the CER right-of-way. Such cases of violations of Chinese rights by Russian railway engineers provoked a discussion between Russian ministers on the issue of organizing a Russian court in Manchuria. The specific case of engineer Luzhansky reflects the colonial behavior and the subject's reaction in frontier territory. This article considers only a local case of the exercise of a special imperial right by a railroad technician and the restriction of his activities as a result of violations of the law, corporate ethics, and the 1898 lease agreement.

Background: Previous studies show that fermentation using Aspergillus oryzae and Rhizopus oligopsorus increases the aglyconic isoflavone in soybean with the highest content reached on the seventh day. Still, no research has been done on edamame.
Objective: This study was conducted to validate the method and determine aglyconic isoflavone, daidzein, content in non-fermented and A. oryzae and R. oligopsorus fermented edamame using TLC densitometry.    
Method: TLC densitometry method used was validated, then used to determine daidzein content in non-fermented edamame, and edamame fermented with the combination of A. oryzae and R. oligopsorus for four days (D1 - D4).
Results: The TLC method met all the validation method, except for the selectivity. The daidzein content on non-fermented and fermented edamame (D1 - D4) was 0.0354+1.49*10-3, 0.0099+1.19*10-3, 0.0118+0.16*10-3,0.0156+0.65*10-3, and 0.0618+10.67*10-3, respectively.
Conclusion: The highest daidzein content was reached at the fourth day of fermentation.
