Authors: Nghi Tran Huu , Podstrigaev A. S. , Nhan Nguyen Trong , Ikonenko D. A.
Published: November 2023

Introduction. The signal recognition task for the purposes of RF spectrum management can be solved using a signal recognition algorithm with detection at two intermediate frequencies. This algorithm is based on time–frequency analysis using fast Fourier transform (FFT) and signal envelope processing. Due to the relative simplicity of transformations, this algorithm is implemented on commercially available field programmable gate arrays and allows processing received signals in near real-time. However, the justification of the algorithm parameters providing effective signal recognition by the criterion of minimizing the signal-to-noise ratio (SNR) has not performed so far.

   Aim. Justification of parameters of the developed signal recognition algorithm, providing the minimum required SNR at the algorithm input.

   Materials and methods. The efficiency of the developed algorithm was estimated by computer simulation in the MATLAB environment.

   Results. The influence of the parameters of functional blocks and received signals on the efficiency of the developed algorithm was investigated. For chirp, simple pulse, binary, and quadrature phase shift keying signals, the following parameters are recommended: a pulse duration of 5…20 μs; a chirp rate of 0.8…24 MHz/μs; a code duration of 0.5…1 μs. For these signal parameters, the parameters of the algorithm ensuring its efficiency according to the given criterion are as follows: the number of FFT points equals 1024; the Hamming weight window; bandwidths of band-pass filters are 4 MHz; signal envelope amplitude averaging coefficient equals 0.15…0.25.

   Conclusion. The algorithm with the scientifically valid parameters can be used for recognition of signals at the input minimum SNR for the given types and parameters of signals.

Authors: Luc Dao Van , Konovalov A. A. , Hoang Le Minh
Published: November 2023

Introduction. In the past few years, the rapid development and widespread use of unmanned aerial vehicles (UAVs) for solving a variety of tasks has created new threats. The problem of ensuring the safety of protected objects, especially in the area of critically important objects or in places with difficult ornithological conditions (airports, wind power facilities), is of particular importance. In this regard, the issue of detecting small air targets and recognizing their type and degree of danger is acquiring greater importance. This paper presents an algorithm for recognizing air targets based onartificial intelligence technology. The results of a comparative analysis of decision-making methods for recognizing small UAVs and birds based on their trajectory features are presented. The results obtained can be used in the development of systems for recognizing classes of small airborne targets in existing and future radar stations.

   Aim. Development of an algorithm for recognizing small air targets by trajectory features based on machine learning. Implementation and evaluation of the quality of decision-making methods in a given recognition problem.

   Materials and methods. Experimental data on the trajectories of UAVs and birds obtained in a passive bistatic radar system are used. The trajectory parameters of the targets and their statistical characteristics are calculated; a set of features for recognition is formed. Using the MATLAB software package, a program for implementing the recognition algorithm and analyzing the quality of decision-making methods was developed.

   Results. An algorithm for recognizing air targets based on artificial intelligence technology is presented. A comparative analysis of the six most common recognition methods based on machine learning (Naïve Bayes, decision trees, k-nearest neighbors, neural network recognition algorithm, support vector machine, random forests) was carried out, which showed that, under the conditions of this problem, the most effective are k-nearest neighbor method and support vector machine.

   Conclusion. The presented methods can be used to directly determine the class of targets from a set of marks of their trajectories. Further research will be aimed at developing and implementing a real-time recognition algorithm.

Introduction. The requirements for the performance of measuring devices, including their operating frequency, are constantly becoming stricter. This encourages the creation of wide-band microcircuits for application in microwave blocks of devices, such as vector network analyzers (VNA) and spectrum analyzers (SA). One of such microcircuits, used in the receiver system, is a frequency mixer. The operating range of the mixer determines the operating range of the measuring instrument.

   Aim. Research and development of an ultra-wideband integrated circuit for a 13…67 GHz frequency mixer based on the GaAs QSBD technology by Micran JSC.

   Materials and methods. An analysis of existing classic and modified circuit transformers used in mixers was conducted. A modification of the transformer circuit, which allowed a frequency range of 10…70 GHz to be achieved,was proposed. Based on the obtained transformer and GaAs diode technology of Micran JSC, a complete mixer topology was developed and produced. An electrodynamic analysis of the integrated circuit was carried out; measurements were performed using a VNA up to 67 GHz.

   Results. A wideband mixer with a frequency range of 10…67 GHz is developed. A circuit design is proposed based on a balanced circuit with modified transformers and an intermediate frequency output circuit. The calculated dependences and measurement results of the integrated circuit of the mixer are presented. The mixer exhibits a conversion loss of less than 10 dB in the range of 10…67 GHz.

   Conclusion. A new broadband transformer with a range of operating frequencies from 10 to 70 GHz was developed. On its basis, a mixer microcircuit was simulated and manufactured. This microcircuit can be used in the receiving and transmitting units of modern measuring instruments. In terms of its characteristics, the proposed microcircuit is an analog of the Marki Mikrowave MM1-1467L mixer.

Мета дослідження. Проаналізувати діяльність зареєстрованих баптистських громад (ВРЄХБ), п’ятидесятницьких громад (ХВЄ), нелегальних п’ятидесятницьких громад, еміграційні тенденції у них та об’єднавчі легальні процеси, які в останні роки тривалості радянської влади утворили свої самостійні об’єднання чи союзи, котрі діють і донині у всеукраїнському масштабі, на прикладі Львівської, Івано-Франківської і Тернопільської областей. Методологія дослідження базується на принципах наукового пізнання: історизму, об’єктивності, позаконфесійності, світоглядного плюралізму, толерантності, які уможливили вивчення і компаративістику подій і фактів в їх ґенезі та інтегральності, з проекцією на сучасні реалії державно-релігійної політики України. Методи дослідження пов’язані з метою, об’єктом, предметом і науковими завданнями дослідження. Наукова новизна. У наукових дослідженнях майже не охоплено західні області упродовж досліджуваного періоду, що не дає змоги мати цілісну картину їх діяльності, конфесійних трансформацій у них та глибшого розуміння їх служіння в сучасних умовах. Висновки і перспективи подальших розвідок цього питання. Трансформаційні процеси у баптистських і п’ятидесятницьких громадах у досліджуваний період в західних областях України можна поділити на два етапи: повільний – 1976–1987 рр. та інтенсивний – 1988–1991 рр. Якщо на першому етапі кількість громад зазначених конфесій та чисельність у них віруючих хоча й зростала, але незначними темпами, що пояснюється відносно активною атеїзацією суспільства партійно-державними органами радянської влади із використанням нею репресивних методів від так званих «бесід» із священнослужителями та активом цих громад до притягнення їх за порушення законодавства про релігійні культи до адміністративної, а то й кримінальної відповідальності, то на другому етапі спостерігаються швидкі та всеохоплюючі трансформаційні процеси у баптистських і п’ятидесятницьких громадах, які призводять до розпаду ВРЄХБ та утворення таких п’ятидесятницьких центрів, як ВСХВЄ – п’ятидесятників і СВЦХЄВУ, а також нададуть нового імпульсу діяльності РЦЄХБ та утвореному Союзу ЄХБ України, котрі будуть у наступних роках діяти під зазначеними назвами: ВСОЄХБ і СРЦЄХБ, які формують свої обласні релігійні структури і розпочинають багатовекторну діяльність на користь українського суспільства.

Проаналізовано особливості функціонування національної економіки в умовах дії воєнного стану. Розкрито зміст основних макроекономічних проблем, які постають для економіки в умовах дії воєнного стану, серед яких суттєва деформація структури сукупної пропозиції та сукупного попиту, глибока криза на ринку праці, фізичне руйнування інфраструктури та активів, втрата ринків збуту українськими підприємствами-експортерами, порушення економічних зв’язків, руйнування логістичних маршрутів, розрив ланцюгів формування доданої вартості. Проблематика повоєнного відновлення та розвитку української економіки є предметом різноманітних дискусій. Спрямування напрямів відновлення економіки України має враховувати новітні геополітичні й економіко-інституційні виміри. Доведено, що одним із найважливіших макроекономічних викликів для економіки України є її велика залежність від імпорту, що веде до зростання дефіциту торговельного балансу та загрожує макроекономічній стабільності. Визначено, що створення нової моделі економічного розвитку України після завершення воєнних дій має враховувати умови соціально-економічного розвитку в умовах глобальної конкуренції. Встановлено, що з позиції реалізації національних інтересів важливим є стимулювання державою реалізації підприємницького потенціалу внутрішнього виробництва на основі поглиблення дерегуляції, розширення кредитування та надання підтримки виходу на зовнішні ринки. Визначено, що в Україні потрібна економічна політика виваженого протекціонізму, активної підтримки підприємництва й стимулювання високотехнологічного експорту. Саме така політика вимагатиме й значного поглиблення обґрунтованості інструментарію реалізації заходів держави, спрямованих на стимулювання повоєнного відновлення української економіки.

Authors: Bing Zhang Jing , Yap Soon Cheng , Yie Leong Wai
Published: November 2023

Dialysis is the treatment for chronic kidney disease (CKD) patients, including acute or end-stage renal disease (ESRD), by performing the filtration of toxic or waste substances from the patient’s body. Haemodialysis (HD) and peritoneal dialysis (PD) are common treatments for dialysis patients with the use of extracorporeal dialysis machines such as haemodialysis machines or automated peritoneal dialysis (APD) for HD and PD, respectively. For HD, is required a dialyser act as a single-use consumable during the treatment of the patient. However, the major concern on the haemodialysis machine might be the issue on false sense during the treatment. The leakage detector of the dialysis machine is important to detect and sense the parameters when that is a leakage event, such as blood leakage at the dialyser or arteriovenous fistula (AVF) dysfunction. Thus, this study provides a review of leakage detection that has been developed with different methodologies of the sensing unit on a haemodialysis machine.

Remaja adalah dimana seorang anak beranjak dewasa sehingga memiliki perubahan di postur tubuh dan masa dimulainya organ reproduksi. Pemahaman tentang reproduksi harus di mengerti anak yang beranjak dewasa agar paham menjaga kesehatan pada perkembangan meranjak dewasa. Ada juga dampak jika remaja tidak memahami perkembangan organ yang mulai bereproduksi yaitu dapat timbul masalah karena kurangnya pengetahuan tentang kesehatan reproduksi, adanya penyakit yang timbul akibat kurangnya pemahaman yaitu penyakit menular seksual dan infeksi seksual menular. Tujuan dari penelitian ini adalah untuk menilai tingkat informasi yang dimiliki remaja mengenai kesehatan reproduksi. Periode pertumbuhan dan perkembangan manusia dikenal sebagai remaja, yang mengikuti masa bayi tetapi mendahului kedewasaan. (WHO 2011). Dimulainya masa peralihan anak menuju masa remaja akan membawa sejumlah perubahan yang dapat diamati pada ketiga dimensinya: hormonal, sosial, dan kognitif. Masa remaja merupakan masa tersulit dalam hidup seseorang, baik bagi remaja maupun bagi orang tuanya. Anak-anak diberi tugas baru saat mereka memasuki masa remaja dan diajar untuk berubah menjadi orang dewasa yang mandiri. Remaja harus bertanggung jawab untuk menjaga kesehatan seksual mereka dengan cara ini. Intinya, semua remaja harus menyadari pemahaman teman sebayanya tentang kesehatan reproduksi. Bukan hanya bagaimana agar alat reproduksi tetap sehat dan berfungsi dengan baik, tetapi juga bagaimana agar remaja tidak melakukan hal-hal yang melawan hukum. Oleh karena itu sebaiknya remaja diberikan pengarahan dan pengajaran yang tepat untuk memperoleh pengetahuan yang tepat yang harus diketahuinya dan untuk mendidik organ ini.

Constituting community through food charters: A rhetorical-genre analysis
Authors: Spoel Philippa , Derkatch Colleen
Published: November 2023

Communities across Canada are increasingly developing food charters, with at least 22 regional charters published in Ontario alone. As a rhetorical genre, food charters are persuasive actions that articulate not only the kind of food system to which a community aspires, but also the kind of community that it aspires to be. We argue that Ontario’s food charters play an important role in constituting a sense of community identity and values through the rhetorical action of the genre itself. We analyze how this is accomplished through two rhetorical features, the naming of community and the listing of community priorities, showing how these features simultaneously obscure and reveal ideological tensions and logical incongruities within each community’s vision for its food system. Our analysis illustrates how the genre of the food charter both responds to and shapes the diverse, possibly conflicting values that inform food policy and food security initiatives in Ontario, and it offers insight into how the genre itself may inadvertently constrain the action it is intended to perform. 
Exploratory Study for the Development of Road Safety Index on Indian Roads
Authors: Fatima Electricwala , Gupta Lokesh , Kumar Rakesh
Published: November 2023

Road Safety has always been a factor of great concern in India as well as across the world. Road Traffic Accidents have been consistently increasing, and to address this issue, the world's governments declared 2021 to 2030 as the 'Decade of Action' for Road Safety. This rise in accidents can be attributed to the increasing motorization escalation, increasing individual modes of transport, soaring speeds, drinking and driving, increasing transportation network patterns and inefficient enforcement, to name a few. If compendiously scrutinized, the losses due to road traffic incidences are wholly avoidable. A comprehensive study was thus conducted to identify the key aspects which can be attributed to road safety. The six key factors were identified, namely the design of roads, the design of vehicles, the role of the law enforcement agency, the part of the Indian judicial system, the function of the Indian medical system, and general public awareness for developing road safety index. Primary data collection among various population segments identified the relative importance of these factors. The weightage based on the importance of these factors was computed using the Logarithmic Goal Programming Model, and thus, the Road Safety Index was developed.
СТАН ПРАВОВОЇ РЕГЛАМЕНТАЦІЇ ЗАСТОСУВАННЯ ТЕХНОЛОГІЙ ШТУЧНОГО ІНТЕЛЕКТУ
Authors: Миколаєць В. А.
Published: November 2023

Стаття присвячена дослідженню актуальних питань використання досягнень світової науки і техніки, зокрема широкому застосуванню технологій штучного інтелекту у багатьох сферах суспільного життя: медицині, управлінні, обороні, судочинстві, мистецтві, побуті та інших сферах. Зокрема, увага приділяється поняттю штучного інтелекту, законодавству, що забезпечує правове існування вказаних технологій, порівняльному аналізу вирішенню питань, пов’язаних з існуванням та використанням штучного інтелекту у життєдіяльності суспільства у законодавствах країн континентального та загального права; також увага приділяється питанням, які потребують врегулювання під час розробки та вдосконаленні законодавства в цій сфері.

Методологічну основу дослідження склали ряд загальнонаукових та спеціально наукових методів, зокрема: діалектичний метод та формально-логічний метод, соціологічний та порівняльний аналіз, а також системний метод, метод індукції, дедукції, аналізу та синтезу.

Зважаючи на той факт, що використання технологій штучного інтелекту набуває більших масштабів, існує потреба у чіткій правовій регламентації ряду питань, пов’язаних з нормальним їх використанням: авторства, захисту персональних даних, відповідальності за некоректну роботу штучного інтелекту, правового статусу штучного інтелекту тощо. Оскільки законодавство України нині є обмеженим у питанні правового забезпечення зазначених технологій, натомість у кожному конкретному випадку застосовуються норми цивільного, господарського, адміністративного, кримінального та трудового права – існує об’єктивна необхідність нормативного визначення створення, використання технологій штучного інтелекту та забезпечення безпеки, пов’язаної з їх використанням. Найбільш розроблений механізм застосування технологій штучного інтелекту представлений у законодавстві країн Європейського товариства, а враховуючи курс на європейську інтеграцію нашої держави, очевидно, що саме стандарти ЄС у цій сфері будуть покладені в основу відповідних норм українського законодавства в майбутньому.

У результаті дослідження автор доходить висновку про те, що штучний інтелект варто розглядати як чергову нову технологію та правовий інститут, який потребує врегулювання нормами права. Серед питань, які потребують нормативного визначення, зокрема: правовий статус штучного інтелекту, авторські права на твори, створені штучним інтелектом, захист персональних даних, пов’язаних з доступом, збиранням і обробкою їх штучним інтелектом, кібербезпека і застосування штучного інтелекту, права людини і дискримінація, питання відповідальності за дії штучного інтелекту тощо.

Prevalence of Gallbladder Malignancy in Gallstone Diseases
Authors: Akter Shahana , Sharif Shah Muhammad Sharif , Manzur Manzila
Published: November 2023

Background & objective: Carcinoma (Ca) of the gallbladder is a rare disease. But its prognosis is poor. Early diagnosis of Ca gallbladder, though important, is rarely achieved due to lack of symptoms and physical signs. However, it is frequently associated with gallstone diseases. It is, therefore, of utmost importance to do a routine histopathological examination of all gallbladder specimens after cholecystectomy is done for gallstone diseases. The present study was undertaken to find the prevalence of Ca gallbladder in gallstone diseases.
Methods: This descriptive study was conducted in the Department of Surgery, BSMMU Hospital, and in the Public Medical College Hospitals of Dhaka over a period of eight months from July 2011 to February 2012. A total of 1012specimens of gallbladder were taken from the patients who underwent either laparoscopic or open cholecystectomy for gallstone diseases in the above-mentioned hospitals during the study period. Following the operation, the resected specimens or the biopsies taken from the gallbladder were collected in 10% formaldehyde solution and were sent to the Histopathology Departments of the respective hospitals, for confirmation of diagnoses as well as for histological grading and typing.
Result: Of the 1012 cases of operated gallbladder for cholelithiasis, 28(2.7%) cases were histopathologically diagnosed as having Ca gallbladder. The age incidence of Ca gallbladder varied from 43 – 71 years. The highest incidence was observed in the 6th decade (53.6%) followed by the 5th decade of life (28.5%). Out of 28 cases of Ca gallbladder, 15(53.6%) exhibited increased wall thickness. All 28 cases were adenocarcinoma; of them, 25(89.3%) were poorly differentiated and 3(10.7%) were well-differentiated carcinoma. Non-squamous cell carcinoma or other variants were found. The majority (82.1%) of the cases was of infiltrative scirrhous (a hard slow-growing malignant tumor having a preponderance of fibrous tissue) type and the rest (17.9%) fungating type. Staging of the disease stratified 4(14.3%) cases as Stage-IV, 3(10.7%) cases as Stage-Ill, 8(28.6%) cases as Stage-II, and 13(46.4%) cases of Stage-I.
Conclusion: The study concluded that the prevalence of malignancy in gallstone disease is rare. The incidence is highest in the 6th decade of life and females are more often affected than males. As older people with gallstone diseases are at increased risk of having gallbladder malignancy, it is imperative that older patients with gallstone diseases should be routinely examined for evidence of carcinoma.

Published: November 2023

Projects linking conservation and development have been implemented around protected areas with a trust to generate benefits for local communities to garner support for the conservation of biodiversity in Nigeria's protected areas. Hence, this study assessed the Park's benefits to surrounding communities and its impact on wildlife conservation in Kainji Lake National Park (KLNP), Nigeria, to provide park managers with additional information in planning their activities. Four (4) randomly selected villages: Luma, Malale, Wawa and Gada Oli were surveyed with 110 questionnaire copies. The results show that the majority of respondents (55.5%) are males, whereas most households (38.18%) comprise 6 to 10 members. The major occupation of the respondents revealed that 42.7% were farmers in the surrounding national park, followed by traders (20%) and civil servants (16.4%). Most of the respondents were non-indigenes of the communities, while 37.20% of the respondents indicated that their monthly income was between ₦20,001 and ₦40,000. Eighty four per cent (84%) of the respondents agreed that the host communities' derived lots of benefits from KLNP, which include the donation of farm inputs (38.18%), employment (18.18%), empowerment programmes (16.36%) and infrastructural development (14.55%) through a majority (65%) of respondents indicated that there is no communities' involvement in the planning of park-initiated projects. The study further established that there is a significant relationship between income and the perception of respondents to wildlife conservation. However, other variables, such as age, sex, occupation, education, and household size are not significant to the notion. This study shows that Kainji Lake National Park's surrounding communities have an overall positive attitude towards the park. However, local people's responses to specific concerns and benefits showed a mixed perception. It is imperative for park authority to build on the communities' perception of conservation and development outcomes.

An incubation experiment was undertaken to evaluate the effects of azolla, grass, water hyacinth, and peanut residues for amending some soil properties. The experiment was laid out in pots comprising 7 treatments, viz. T1: Control, T2: Azolla (Azolla pinnata) @ 100 g/pot, T3: Grass (Phleum pretense) @ 100 g/pot, T4: Water hyacinth (Pontederia crassipes) @100 g/pot, T5: Peanut (Arachis hypogaea) @ 100 g/pot, T6: Azolla @ 50 g/pot  + Water hyacinth @ 50 g/pot,  and T7: Peanut@ 50 g/pot + Grass @ 50 g/pot. The results revealed that peanut treated soils (T5) played an important role in enhancing soil properties significantly (p < 0.05) and the values of soil organic carbon (SOC), pH, nitrogen, moisture content and cation exchange capacity (CEC) reached at an optimum level to support microbial growth over a year.

Objetivo: determinar os impactos da pandemia da COVID-19 na saúde mental dos idosos de uma Unidade Básica de Saúde (UBS) em Guanambi, Bahia, Brasil. Método: Trata-se de um estudo quantitativo de corte transversal, realizado no segundo semestre de 2022, em que foram analisados dados relacionados a pandemia da COVID-19 coletados por meio de um questionário autoaplicado, assim como de sintomas depressivos e ansiosos-fóbicos investigados por meio da Escala de Depressão Geriátrica (GDS) e do Inventário de Ansiedade Geriátrica (GAI). Os dados foram analisados por estatística descritiva e análise bivariada por ANOVA e Test T de Student. Resultados: A amostra conteve 42 idosos, a maioria deles não teve COVID-19 (78,6%), entretanto 66,7% tiveram familiares diagnosticados e 61,9% perderam alguém conhecido pela doença. De modo geral, pontuaram baixo na GDS e no GAI, com uma média de 3,54 ± 2,49 na GDS e de 6,57 ± 5,82 no GAI. A perda de alguém conhecido por COVID-19 esteve associada a uma maior prevalência de sintomas ansiosos no GAI (p valor 0,003). O sexo, nível de escolaridade, renda familiar mensal, necessidade de atendimento médico, perdas econômicas na pandemia e a presença de comorbidades no momento do diagnóstico de COVID-19 não pareceram estar associadas à sintomas depressivos e ansiosos. Conclusão: a perda de conhecidos pela COVID-19 esteve associada ao desenvolvimento de sintomas depressivos e, principalmente, ansiosos. As perdas econômicas decorrentes da quarentena não pareceram influenciar sobre a prevalência de sintomas psiquiátricos.
Gambaran Jumlah Trombosit dan Leukosit Saat Awal Masuk Rumah Sakit Pada Pasien Demam Dengue di RSUD Wates Periode April 2020 - April 2021 dan Tinjauannya Menurut Perspektif Islam
Authors: Firdaus Aulia Najmi Yatrib Ul , Purnamasari Endah , Arifandi Firman
Published: November 2023

Latar belakang: Demam dengue adalah penyakit yang disebabkan oleh infeksi virus dengue yang ditularkan oleh gigitan nyamuk yang membawa virus dengue tersebut. Pada pasien dengue akan ditemukan kondisi rendahnya jumlah sel darah putih (leukopenia) dan kondisi rendahnya jumlah keping darah (trombositopenia). Leukopenia mencapai puncaknya sesaat sebelum demam turun dan normal kembali pada 2-3 hari setelah demam turun. Penurunan trombosit umumnya mengikuti turunnya leukosit. Dalam kitab Al furuq terdapat kaidah yang menyatakan bahwa hukum perantara mengikuti hukum tujuannya sehingga hukum pemeriksaan laboratorium dengue menjadi wajib mengikuti dengan hukum tujuannya yaitu untuk menjaga kesehatan.Metode: Jenis penelitian berupa deskriptif analitik dengan pendekatan cross sectional. Penelitian ini menggunakan hasil laboratorium pemeriksaan trombosit dan leukosit pasien demam dengue saat awal masuk RSUD Wates Periode April 2020 – April 2021. Analisis statistik dilakukan dengan Uji Korelasi Spearman untuk melihat hubungan antara usia dengan jumlah trombosit.Hasil: Pada pasien demam dengue saat awal diperiksa, jumlah leukosit menurun lebih dahulu sebesar 26 sampel (50%), jumlah leukosit dan trombosit menurun bersamaan sebanyak 15 sampel (28,8), jumlah leukosit dan trombosit normal sebanyak 7 sampel (13,5%), dan jumlah trombosit yang menurun lebih dahulu sebanyak 4 sampel (7,7%). Sehingga pada pasien demam dengue leukosit mengalami penurunan jumlah terlebih dahulu saat awal diperiksa. Kemudian berdasarkan uji statistik didapatkan nilai p lebih besar dari 0.05 sehingga dikatakan tidak terdapat hubungan yang signifikan antara usia dengan jumlah trombosit pada pasien demam dengue saat awal diperiksa.Kesimpulan: Penurunan trombosit mengikuti turunnya leukosit dan tidak ada hubungan antara usia dengan jumlah trombosit pasien demam dengue.
The Effect of Fermented Honey on Seminiferous Tubule Cells While being Induced by Cisplatin and Islamic Perspective Review
Authors: Ulviena Lulu , Hadi Restu Syamsul , Arifandi Firman
Published: November 2023

Background: Cisplatin is the most effective cancer treatment used in chemotherapy. Cisplatin works by inducing oxidative stress, but it also has toxic side effects on healthy cells in the male reproductive organs. Therefore, there is a need for a solution to reduce the side effects of cisplatin. Honey fermentation is a natural substance that can reduce the toxicity of cisplatin. Honey is known as “The food of God” which is a gift of sustenance from Allah SWT due to its extraordinary benefits. Methodology: This study utilized primary data with an experimental posttest-only control group design conducted in vivo. The research involved four experimental groups of rats: a control group without any treatment, a cisplatin group, a 5% honey fermentation group exposed to cisplatin, and a 10% honey fermentation group exposed to cisplatin. All rats were weighed before, during, and after the treatment. Subsequently, HE staining was performed for both descriptive and quantitative observations. Results: Honey fermentation can provide a protective effect on primary spermatocytes and Leydig interstitial cells, almost reaching normal levels. The highest improvement was observed in the 5% honey fermentation group for primary spermatocytes and the 10% group for Leydig interstitial cells. Conclusion: Honey fermentation administration can be protective for testicular organ cells against the side effects of cisplatin. From an Islamic perspective, Allah has created honey for consumption, as mentioned in Surah An-Nahl.

Published: November 2023

One of cryptography algorithm which used is beaufort cipher. Beaufort cipher has simple encryption procedure, but this algorithm has good enough endurance to attack. Unauthorized people cannot break up decrypt without know matrix key used. This algorithm used to encrypt data in the form of text called plaintext. The result of this algorithm is string called ciphertext which difficult to understood that can causing suspicious by other people. Beaufort cipher encryption tested with avalanche effect algorithm with modified one, two, three and all key matrix which resulting maximum 31.25% with all key modification so another algorithm is needed to get more secure. Least Significant Bit (LSB) used to insert ciphertext created to form of image. LSB chosen because easy to use and simple, just alter one of last bit image with bit from message. LSB tested with RGB, CMYK, CMY and YUV color modes inserted 6142 characters resulting highest PSNR value 51.2546 on YUV color mode. Applying steganography technique has much advantage in imperceptibility, for example the image product very similar with original cover image so the difference can not differentiate image with human eye vision. Image that tested as much ten images, that consist of five 512 x 512 and five 16 x 16 image. While string message that used is 240, 480 and 960 character to test 512 x 512 image and 24, 48 and 88 character to test 16 x 16 image. The result of experiment measured with Mean Square Error (MSE) and Peak Signal Ratio (PSNR) which has minimum PSNR 51.2907 dB it means stego image that produced hood enough. Computation time calculation using tic toc in matlab resulting fastest value 0.041636 to encrypt 2000 character and the longest time is 4.10699 second to encrypt 6000 character and inserting to image. Amount of character and amount of multi algorithm can affecting computation time calculation.
The ornithology of Agnes Block (1629–1704): Dutch naturalist, artist, collector and patron
Authors: Martinez Deniz
Published: November 2023

Agnes Block (1629–1704) was a Dutch Mennonite naturalist, collector and patron, as well as an artist herself. In a family portrait by Jan Weenix (1642–1719) depicting Block at her renowned garden estate De Vijverhof near Wageningen, it is the fruiting pineapple, Ananas comosus, believed to be the first to be successfully cultivated in the Dutch Republic, which usually receives the most attention. However, while best known for such horticultural achievements and botanical interests, little attention has been paid to her ornithological endeavours. Block is known to have kept an aviary as well as a natural history cabinet which probably included specimens of birds. She also commissioned at least 18 artists to work for her, and had her exotic birds documented on paper just as she did her plants. In Weenix's painting, it is a drawing of a bird she proudly displays. What bird is it, and why does it matter? This paper offers an identification of the bird depicted –  Cyanerpes cyaneus (red-legged honeycreeper) found only in Neotropical America – and considers what it can tell us about Block's unrecognized place in early modern European ornithology.
The Heriot of Ramornie annotated copy of Flora Glottiana: an early nineteenth-century Flora of Fife
Authors: Noltie Henry J.
Published: November 2023

The ownership of a copy of Flora Glottiana heavily annotated in the 1810s is discussed. The annotations are attributed to James Heriot ( né Maitland) or his wife Margaret ( née Dalgleish), owners of the estate of Ramornie in Fife. The marginalia turn the volume into a local Flora for Fife, vice-county (vc) 85; some of the more interesting species records and their localities are discussed. Many of the localities are estates that belonged to Maitland or Dalgleish relations, suggesting that botanical recording formed part of a network of familial and social interactions. Such links went beyond Scotland and connections with India are discussed, as is the question of how the volume ended up in the ownership of John Hutton Balfour.
Carved in Granite: C.S. Lewis’s Revivalism in The Nameless Isle
Authors: Wilson Wise Dennis
Published: November 2023

The alliterative poetics used by C.S. Lewis have often proved a critical challenge for scholars without the right kind of medievalist training. In Lewis’s most ambitious contribution to the Modern Alliterative Revival, The Nameless Isle, I argue that he has a strong interest in maintaining fidelity to the Old English alliterative metre, particularly in regards to Sievers types and hypermetric verses, yet he partakes of several adaptations and concessions to Modern English that makes his narrative romance, in some ways, a more successful model than Tolkien’s contemporary ‘arch-purist’ text, The Fall of Arthur. By and large, while questions about a poet’s faithfulness to a historical alliterative tradition are important, deviations from strict fidelity can be even more important yet – they reveal the specific metrical challenges faced by poets in trying to resurrect the alliterative metre. Only by analysing the metrical data behind a poem like The Nameless Isle can we understand what a revivalist may be specifically trying to accomplish with their revivalism.

Authors:   Institute of State and Law of the Russian Academy of Sciences, Moscow Russian Federation, LIZIKOVA M.S.
Published: November 2023

The article notes the objectively determined need for digitalization in the field of the use of atomic energy, its growing role in the development of innovative nuclear energy technologies, and identifies the problems caused by the widespread use of digital technologies in this area. The current state of the national legal regulation of digital transformation in general, and in the energy sector in particular, has been studied. Based on the assessment of the impact of digital transformation on international legal regulation in the field of the use of atomic energy, the author made an attempt to identify features that reflect its structural changes at this stage. It is concluded that international nuclear law responds in a timely manner to the rapid development and spread of digital technologies, which is manifested in its adaptability to changes, increased hybridization of legal regimes and the impact on values, as well as their interconnection and conditionality. The high pace of digital transformation of the legal regulation of the area under consideration requires regular comparative legal research in order to determine its scale and identify relevant changes.
