Authors: Rahman Sultana Nadira , Hossain S M Monowar , Ashraf Rashed
Published: December 2022

Introduction: Bacteria that enter the bloodstream and mobile to the brain cord cause bacterial meningitis. The disease is less frequent in developed countries compared to developing countries. In Bangladesh, bacterial meningitis constitutes 25% and the case fatality rate was 14%. The mortality from meningitis is near 100% in untreated individuals and can still be up to 40% in children who received appropriate antibiotic therapy in developing countries. Aim of the Study: The study aims to investigate the specificity, sensitivity, and diagnostic accuracy of CSF-CRP in the diagnosis of Acute Bacterial Meningitis (ABM). Methods: An observational cross-sectional study was carried out in the Department of Pediatric Medicine, Dhaka Shishu Hospital (DSH), from 01 Jan-2017 to 30 Jun-2017. A total of 100 patients were enrolled in this study following the inclusive criteria. Data were collected using the predesigned semi-structured questionnaire. Verbal consent was taken before recruiting the study population. Completed data forms were reviewed, edited, and processed for computer data entry. Result: Among the study population majority of patients (43, 43.0%) were 0-2 years old. One-third of bacterial meningitis (35,35.0%) occurs commonly at an early age (0-2 years). Out of fifty- seven cases (n=57) of bacterial meningitis, twenty-two cases were culture negative and thirty-five cases were culture positive. In the case of bacterial meningitis, in fifty-one cases (51,89.4%) out of fifty-seven, the CSF CRP test was truly positive, with mean±SD 21.7±10.9, false negative were only six cases (6, 10.5%). In aseptic meningitis thirty-nine cases (39,90.6%) out of forty-three cases, the CSF-CRP test was truly negative, and false positive were four cases (4,9.3%). The sensitivity of CSF CRP in differentiating bacterial meningitis from aseptic meningitis was 89.47%, specificity 90.69%, & diagnostic accuracy was 90%. Conclusion: Bacterial meningitis is fatal and more communal in children under one year of age to sixteen years of age. Increased consciousness and initial gratitude and apposite antibiotic treatment can decrease morbidity and mortality. Diagnostic accuracy can be applied as the initial test for the diagnosis of bacterial meningitis.
Consequences of Money Laundering and Persisting Losses of the Country: A Reference of Bangladesh
Authors: Ferdousy Laila
Published: December 2022

Money laundering is a multidisciplinary issue that has gained prominence since the late 1980s. The word "laundering" literally means "to wash" or "to remove dirt." It's been characterized as the transformation of illegal proceeds into assets that can't be linked to the original crime. Money is frequently transferred from one sector to another, and the same money is frequently transferred to another sector in such a way that it is challenging to identify the source. As a result, law enforcement is unable to identify the illicit source. This means through the transaction cycle; money laundering is the process of legalizing black money or transferring the amounts as lawful revenue while hiding the source of the money received. The objective of the study is to have a thorough understanding of the money laundering scenario and how it affects the domestic and global economy, assess the money laundering challenges facing financial institutions, and offer strategic methods for financial institutions to mitigate the risks. Bangladesh is a victim of money laundering and other forms of financial crime. In many ways, the competent authority provides additional opportunities to whiten money. This study first identifies the necessity of anti-money laundering for public and private banks and non-bank financial institutions operating in Bangladesh. The major finding is recurrent amnesties harm corruption and money laundering in Bangladesh. Corruption and money laundering in Bangladesh are projected to decrease if this report adopts recommendations. This will ensure fairness in society in many ways, such as prohibiting criminal activity and will help to prepare sustainable development programs and their achievement and allow honest taxpayers to purchase properties on an equal footing. Bangladesh's government should cooperate with other nations to combat money laundering and constantly upgrade its methods for enforcing laws and regulations.

Published: December 2022

Introduction: The intensity of the work and the diversity of the acts imposed, in the operating room, provided organization and complementarity of the different actors. The dysfunctions observed are the cause of delays, reports or additions to the operating program our study consisted in evaluating, within the our department of operating theaters, the deadlines of patients who were to be performed under general anesthesia in scheduled surgery, from their arrival in the operating room until the incision, and to identify the causes and possible consequences. Materials and Methods: This is a prospective observational study carried out at HMIMV, between March 1, 2018 and April 1, 2018, Results: The median waiting time in the reception room was 42 minutes, and 65% of patients waited between 25 and 62 minutes the main causes of delay in the operating room were at 38% of cases, the unavailability of the anesthesiologist. In more than 22% of cases the non-availability of State Certified Nurse Anesthesiologist in 19% of cases the unavailability of the surgeon. We then find almost 5% of expectations due to equipment defective or missing. Some causes were not specified for nearly 3% and about 3% of cases the non-availability of the State-certified operating room nurse. It is in the sectors of orthopedics and digestive endoscopy that predominates expectation of surgeons and to a lesser extent that of anesthesiologist-resuscitator. However the unavailability of the anesthesiologist-resuscitator was predominant in visceral surgery and in Gynecology. Conclusion: Optimizing an operating theater means making it possible to operate on more patients, in different better safety conditions and with a level of quality and comfort for the patient satisfied.

Published: December 2022

End-stage kidney disease (ESKD) is a serious condition that has a significant impact on patients' lives. The most preferred treatment is to get a kidney transplant, or the patient is shifted to dialysis options including haemodialysis (HD) and peritoneal dialysis (PD). Peritoneal dialysis is one of the effective modalities for the treatment of end-stage kidney disease (ESKD), but it was found to be associated with a serious complication called peritoneal dialysis- associated peritonitis (PDAP). The consequences of PDAP have been found to include removal of the catheter, relapse, transfer to haemodialysis, and death. Thus, it is usually treated using the appropriate antibiotic, which is based on the results of the culture. However, most of the conventional antibiotics used for the treatment of PDAP are not currently showing effectiveness, which is due to the growing resistance worldwide among the causative micro-organisms including Gram-positive and Gram-negative bacteria. Therefore, newer antibiotics that can eradicate these high-resistance microorganisms are required. This article reviews the available examples of novel antibiotics that can be used for peritonitis caused by strains that are showing resistance against conventional antibiotics. Examples include antibiotics like oxazolidinone, lipoglycopeptide, glycylcycline, moxifloxacin and cephalosporins.

Joint effusion is a common clinical problem throughout the world. Synovial fluid analysis is one of the most important diagnostic tests to differentiate various inflammatory and non-inflammatory joint diseases. Gross examination and cell count of synovial fluid are two important test modalities. A comparison of performances of the tests would enable us to emphasize on the diagnostic procedures for better outcomes. A total of 105 cases were included in this study, performances of the tests such as accuracy, sensitivity, specificity, positive and negative predictive values of each test modality were calculated for comparison. Joint effusions were diagnosed as 19 rheumatoid arthritis, 12 non- inflammatory, 15 inflammatory, 14 infective, 7 tubercular, 4 traumatic, 6 osteoarthritis, 5 crystal induced arthritis, 6 non- specific arthritis and 8 normal cases. Accuracy, sensitivity, specificity, PPV and NPV of cell count were 76.19%, 72.72%, 94.11%, 98.46% and 40% respectively and accuracy, sensitivity, specificity, PPV and NPV of gross examination were 71.42%, 68.18%, 88.23%, 96.77% and 34.88% respectively. The individual parameters of synovial fluid study overlaps among each other test modalities and a combination of test procedures would yield better performances for diagnosis.

The features of the multi-parameter process control based on individual observations, when sampling during monitoring is impossible due to the complexity of measurements or is not economically feasible, are considered. Monitoring of multidimensional scattering usually by using the generalized variance algorithm is carried out, however, when controlling for individual observations, a number of problems arise. An approach to estimating the covariance matrix to solve this problem is proposed.

TERRITÓRIOS LIBERTÁRIOS
Authors: Rodrigues Glauco Bruce
Published: December 2022

Durante a Guerra Civil Espanhola (1936-1939), uma grande parcela dos trabalhadores urbanos e camponeses espanhóis engendrou um processo de caráter revolucionário pautado nos ideais anarquistas formulados ao longo do século XIX e início do século XX. Reunidos em sindicatos e organizações autônomas, esses protagonistas iniciaram um vigoroso e consistente processo de expropriação e coletivização dos meios de produção e instituíram formas de autogestão política e econômica em diversas partes e escalas do território espanhol. Novas dinâmicas de organização da produção e da política foram instituídas a partir da criação de estruturas horizontais e autônomas do exercício do poder. Neste artigo vamos realizar uma análise da experiência anarquista no processo de autogestão e autoplanejamento urbanos na cidade de Barcelona. Na introdução apresentamos uma síntese do contexto em que se desenvolveu a Guerra Civil Espanhola, em seguida realizamos uma análise da dinâmica da cidade antes do início da guerra e, por fim, buscamos identificar e analisar as estratégias e práticas dos anarquistas espanhóis em relação aos processos de autogestão e autoplanejamento urbanos, destacando os serviços, a infraestrutura e a questão da habitação e, dessa forma, avaliar quais foram as transformações realizadas pelos trabalhadores na dinâmica do espaço urbano de Barcelona.

Authors: Sauer Sérgio
Published: December 2022

Este texto é um retorno à tese e às pesquisas realizadas em assentamentos e acampamentos no estado de Goiás, no início de 2000. O objetivo foi entender por que as pessoas lutam por terra ou o “sentido da terra”, analisando práticas sociais, representações, re-apropriação de valores, ou seja, a construção de habitus na luta pela terra, em meio às transformações sociais, econômicas, políticas e culturais da modernidade ocidental. Com base em noções de Pierre Bourdieu, as reflexões desvelaram habitus, representações e práticas sociais, forjadas nos acampamentos e assentamentos. A participação nas lutas e a terra (sonhada ou conquistada) produzem novas representações, ressignificações da identidade social, constituindo processos sociais e agentes na “recriação” do mundo e “reinvenção” da sociedade no campo brasileiro.elocation-id: e2230211Recebido: 8.jul.2022 • Aceito: 21.out.2022 • Publicado: 7.dez.2022Artigo original / Revisão por pares duplo-cego / Acesso aberto

Published: December 2022

В связи с развитием волоконно-оптической техники и полностью оптических сетей разработка оптических переключателей является актуальной задачей. При этом важно использование технологий создания систем без преобразования оптического сигнала в электрический сигнал и обратно.

Целью данной работы является определение возможности применения изгибов оптического волокна для создания оптических переключателей.

Для проведения исследований была разработана экспериментальная установка, позволяющая определять величину потерь мощности оптического излучения, вносимых изгибом оптического волокна.

В качестве объекта исследования в данной статье использовались одномодовые оптические волокна G652, G655 и G657, которые находят широкое применение для передачи информации в современных волоконно-оптических линиях связи.

Получено, что для оптического волокна G652 и G655 при длинах волн оптического излучения 1310, 1490, 1550, 1625 нм, а для оптического волокна G657 при длине волны - 1625 нм, существуют радиусы изгиба оптического волокна, при которых наблюдается практически полное ослабление мощности оптического излучения (более 80 дБ). Определено, что значение радиуса изгиба, для которого наблюдается практически полное ослабление мощности оптического излучения мощностью 1 мВт, зависит от типа оптического волокна. Для исследуемых типов оптических волокон наибольшее значение такого радиуса наблюдалось для волокна G655 при всех длинах волн.

Предложено устройство оптического переключателя на основе изгибов оптического волокна и представлены его характеристики. Также установлено, что в таком оптическом переключателе целесообразно использовать оптические волокна G652 и G655.

Результаты, полученные в этой статье, могут найти применение при разработке компонентов для волоконно-оптических систем передачи данных.
M-ARY CDMA SCHEME WITH CCSK MODULATION AND PARALLEL INTERFERENCE CANCELLATION TECHNIQUE
Authors: Гепко Ігор
Published: December 2022

In this paper, we tackle the problem of implementation a parallel interference cancellation scheme for multi-user detection (MUD) in M-ary CCSK-modulated CDMA system. Complexity remains the main obstacle to the practical implementation of MUD and a factor limiting, if not the very possibility, then the feasibility of using high order M-ary modulation formats for applications such as low-probability-of-intercept systems with a large spreading factor or, myriads of small self-powered IoT devices. The design of MUD algorithms for M-ary systems leads to a new round of growth in the receiver complexity comparing with the binary modulation. Demodulator has a major impact on the complexity of CDMA system. Cyclic code-shift keying (CCSK) is a modulation technique which is designed to reduce the complexity of M-ary signaling. In this, each symbol is a circularly shifted version of a single code sequence. Assuming synchronization, the receiver cyclically correlates the input signal plus noise with the base sequence and estimates the position of the correlation peak. The preliminary stage of the proposed scheme is a conventional multi-channel CDMA receiver. The preliminary estimates of the data is multiplied by user codes and amplitude estimates in the spreader, and then fed to the adder to generate the MAI estimates. After the latter are subtracted from the group signal, K-dimensional vector of cleared user signals is passed to the matched filter bank to form the refined estimates of the data. At each subsequent stage, the estimates of the output data of the previous stage are used as input data. The complexity gain is the ratio of the number of computations for finding cyclic convolution and, the amount of computations for finding M linear convolutions, i.e., M/log2M. Since the performance of the algorithm is sensitive to the reliability of the preliminary decisions, there are strict criteria for the selection of spreading codes: the length which must be an integer power of 2, the large family size, good periodic autocorrelation and good cross-correlation properties. To examine the proposed algorithm using computer simulation, we selected minimax periodic and odd-periodic complementary codes, the properties of which are close to the properties of the codes used in the CCSK scheme implemented in Link-16 protocol tactical data networks JTIDS and MIDS. Our study shows that the gain over the conventional receiver increases as the SNR increases, achieving 15 dB for BER 10-5. The system with complementary codes outperform system based on minimax PN-codes, achieving a target bit error rate at a lower SNR.

Kematian bayi adalah salah satu persoalan pelik yang kerap kali dihadapi oleh negara-negara berkembang. Kematian bayi merupakan faktor penting yang mencerminkan keadaan derajat kesehatan suatu masyarakat. Indikator  ini dilihat karena sensitifnya bayi merespon kesehatan lingkungan yang dibentuk dari kondisi sosial masyarakat, termasuk status sosial orang tua di lingkungan tersebut.

Di sinilah kemudian hadir kkonsep maqashid syariah yang memberikan peluang penafsiran dalam mengatasi tingginya Angka Kematian Bayi (AKB). Dalam memahami teks-teks al-Qur’an dan Sunnah, maqasid Syari’ah digunakan untuk menemukan adanya maksud atauu tujuan Allah dan Rasul-Nya dalam merumuskan hukum-hukum Islam. Abu Ishaq al-Syatibi menerangkan lebih tegas lagi dengan memerinci maksud atau tujuan tersebut menjadi 3 macam tingkatan, yaitu kebutuhan dharuriyat, kebutuhan hajiyat, dan kebutuhan tahsiniyat

The basic structural features of the Madden-Julian oscillation (MJO) in the lower and upper troposphere of the tropical zone are demonstrated. The problems associated with determining the main mechanisms of its formation are identified. Various approaches to the MJO quantification are considered. Using 850 and 200 hPa zonal wind speed from the ERA5 reanalysis datasets, as well as NCEP/NOAA satellite-derived data on outgoing longwave radiation, the main disadvantages and advantages are shown for one of the possible quantitative criteria of the MJO (RMM index). The results of the study are supposed to be operationally used in the NEACC’s subseasonal meteorological forecasts. Keywords: Madden-Julian Oscillation, RMM index, subseasonal foresact

The purpose of this study was to analyse the correlation among the health-related fitness, BDNF, and cognitive function in elderly. 27 male and 31 female participants who live in B city were performed health-related fitness test, body composition, blood analysis, and cognitive functional test. It was used Pearson’s correlation coefficient to verify the correlation among the variables. Cardiorespiratory fitness, muscle strength, flexibility and the score of cognitive functional test decrease according to aging. There was no correlation between BMI and health-related fitness factors. However, % of body fat was significantly correlated with BDNF. Cardiorespiratory fitness and muscle strength had statistically significant relationship with cognitive function, but flexibility was no relation with cognitive function. In conclusion, The exercise program which is to prevent from decreasing cognitive function and dementia for elderly may consist of improving cardiorespiratory fitness, muscle strength, and % of body fat.

Selective adaptation of German /r/: A role for perceptual saliency
Authors: Mitterer Holger , Reinisch Eva
Published: December 2022

In three experiments, we examined selective adaptation of German /r/ depending on the positional and allophonic overlap between adaptors and targets. A previous study had shown that selective adaptation effects with /r/ in Dutch require allophonic overlap between adaptor and target. We aimed at replicating this finding in German, which also has many allophones of /r/. German post-vocalic /r/ is often vocalized, and pre-vocalic /r/ can occur in at least three forms: uvular fricative [ʁ], uvular trill [ʀ] and alveolar trill [r]. We tested selective adaptation between these variants. The critical questions were whether an allophonic overlap is necessary for adaptation or whether phonemic overlap is sufficient to generate an adaptation effect. Surprisingly, our results show that both assertations are wrong: Adaptation does not require an allophonic overlap between adaptors and target and neither is phonemic overlap sufficient. Even more surprisingly, trilled adaptors led tomoreadaptation for a uvular-fricative target than uvular-fricative adaptors themselves. We suggest that the perceptual salience of the adaptors may be a hitherto underestimated influence on selective adaptation.
