The effect of mindfulness meditation on working memory: An observational study in MBBS students of RVM Institute of Medical Sciences and Research Center, Siddipet, Telangana
Authors: Chakrabarty Mousumi , Shinde Priya
Published: February 2023

Background: Meditation is a practice that has been shown to improve calmness, enhance attention, and produce a focused mind. Mindfulness is the quality of being fully engaged with whatever we are doing, being free from distraction. Students nowadays are stressed due to increasing competition relating to their academic performance and career building which, in turn, affects their performance and mental health. Most studies which show that mindfulness meditation improves focus, attention, or memory were done under supervision in serene environment away from the hustle and bustle of modern life. Our study aimed to see whether some benefit of such practice could also be attained in our everyday life settings when done for a short time and without much training or supervision.

Aims and Objectives: The aims of this study were to investigate the effectiveness of short-term mindfulness meditation on working memory in MBBS students using visual memory test
and compare with a control group.

Materials and Methods: Total 50 students were taken and divided into two groups-test and control. A baseline measurement of their working memory by visual memory test was done. A similar test was repeated after 8 weeks of regular mindfulness meditation exercise in the test group while the control group continued with their previous routine. The results were compared with their previous performance as well as with the control group using student t-test.

Results: The recorded changes were analyzed for statistical significance. The results showed statistically significant improvement in the score of test group (P < 0.01).

Conclusions: Our study showed that a period of 8 weeks of mindfulness meditation was helpful in improving working memory. By practicing mindfulness meditation, we train our mind to concentrate on the present moment, leaving aside our problems, worries, and stresses. This regular practice may improve brain network training which results in improvement in working memory.

Authors: Darmadi Darmadi , Ruslie Riska
Published: February 2023

Inflammatory bowel disease (IBD) comprises of Crohn’s disease (CD) and ulcerative colitis (UC). This is a chronic inflammation involving gastrointestinal tract. The prevalence of IBD is increasing recently. Approximately, 25% of all IBD cases develope during childhood. Intrinsic and extrinsic factors play important role in the pathogenesis of IBD. Mild form of IBD is more common in children with symptoms ranging from weight loss, rectal bleeding, diarrhea, and abdominal pain. Diagnosis is established based on history, physical examination, laboratory examination, imaging, endoscopy and colonoscopy, and ultimately, histopathology examination. Management includes utilization of aminosalicylates, corticosteroids, immunomodulators, and biologic agents. Nutritional support, psychosocial approach and surgical approach are other therapeutic options. The complications may occur such as micronutrient deficiency, growth failure, increased risk of malignancies, and psychiatric disorders. Routine monitoring of disease progress and growth achievement is mandatory in the management of IBD.

Comparison of the Diagnostic Value of MRCP, CT, and Ultrasonography in Choledochal Stones with the Results of ERCP: Evidence from 1152 Case
Authors: Ugurlu Esat , Dere Osman , Yilmaz Sezgin
Published: February 2023

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP), magnetic resonance cholangiopancreatography (MRCP), computed tomography (CT), and ultrasonography (US) are widely used in the diagnosis of choledochal stones. This study aims to determine the sensitivity and diagnostic contribution of US, CT, and MRCP in detecting common bile duct stones and to compare them with ERCP.
Materials and Methods: The study included 1152 patients who underwent ERCP diagnosed with choledochal stones. Initially, each patient underwent USG, CT, and MRCP. ERCP was performed 2-7 days later. The results were compared with the ERCP results. Sensitivity, specificity, positive predictive value (PPV), Negative Predictive Value (NPV), and F1 score were calculated.
Results: Compared to ERCP, the most effective method in the diagnosis of choledocholithiasis is MRCP (F score: 0.84), CT (F score: 0.73), MR+BT (F score: 0.75), MR+BT+USG (F score: 0.55), and US (F score: 0.43).
Conclusions: ERCP is the gold standard in treating stones in the common bile duct. However, since this method is invasive, its use for diagnostic purposes has decreased due to the possibility of complications. In diagnosing common choledochal stones, MRCP alone is sufficient regardless of other imaging methods.

Authors: Ugurlu Esat , Yilmaz Sezgin
Published: February 2023

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) is a method of diagnosing and treating pancreaticobiliary diseases. ERCP differs from other endoscopic procedures with a greater risk of developing complications. The study aims to share experiences in diagnosing and managing complications in 15000 ERCP cases performed by two general surgeons in two separate general surgery ERCP units in 13 years and to determine appropriate diagnosis and treatment approaches in patients with complications.
Materials and Methods: This study retrospectively evaluated the data of 15000 patients who underwent ERCP with various diagnoses between June 2009 and June 2022 in General Surgery Clinics in two different centers. Age, sex, ERCP indications, comorbidity, and clinical findings of the patients were recorded.
Results: All patients who underwent ERCP were divided into two groups according to the incidence of complications. The patients who developed complications had higher ages, hospitalization days, and intensive care unit admission rates. Comorbidity increased the rate of complication development: amylasemia and acute pancreatitis were the most developed complications, respectively. Women developed more post-ERCP pancreatitis (PEP). Pre-incision, the number of ERCPs applied was not found to affect PEP development. Choledochal stone was the most important indication for ERCP in patients who developed PEP.
Conclusion: ERCP is an invasive procedure, and complications such as acute pancreatitis, hemorrhage, perforation, cholangitis, and cholecystitis develop after this procedure. Determining these complications and related risk factors will be beneficial in terms of patient satisfaction and health expenditures.

The Forgotten Victims of the Atomic Bomb: North Korean Pipokja and the Politics of Victimhood in Japan-DPRK Relations
Authors: Richardson Lauren
Published: February 2023

This article examines the redress campaign waged by activists in Japan on behalf of roughly 2,000 North Korean A-bomb victims (pipokja). These victims were repatriated from Japan after being subjected to the 1945 US nuclear attacks on Hiroshima and Nagasaki, while under colonial
rule. From the early 1990s through to the twenty-first century, activists in Japan pursued redress for these A-bomb survivors in close synchronicity with the redress movements centred on South Korean victims. Highlighting the potential of the individual as entrepreneur within collective action
settings, the redress developments were initiated and largely driven by an activist, Lee Sil-gun (1929–2020).
 Although Tokyo and Pyongyang were initially reluctant to acknowledge that A-bomb survivors existed in North Korea, in the face of sustained pressure by the Japan-based
activists, the two governments facilitated a limited redress process for the victims by making various concessions on the issue. How did these activists navigate the structural constraints of the authoritarian North Korean state and the volatile bilateral relationship in enacting their transnational
activism? How were they able to elicit concessions on their redress objectives from Tokyo and Pyongyang in the absence of formalized diplomatic relations? Drawing on fieldwork conducted in Japan and South Korea, this article probes these questions by empirically tracing and analyzing the evolution
of the redress campaign for the North Korean A-bomb victims. I utilize the concept of polylateral diplomacy to elucidate the dynamic of engagement between the activists and the two governments.
National Research and Development Core Program - Continuity Support for Marine Research
Authors:   National Institute for Marine Research and Development “Grigore Antipa”, 300 Mamaia Blvd, 900581, Constanta, Romania, Pătrașcu Vasile
Published: February 2023

"Launched in 2003, the Core National Research and Development Programme has become an essential source of national funding for scientific research. The marine and coastal fields have had the necessary research support, through the continuous financing of several multi-annual Core Programme, which NIMRD has carried out over time. Thus, NIMRD has run six Core Programs so far. The paper presents funding details from 2003-2020, with an analysis of the financial distribution per program and over time, revealing the influence of political and internal management decisions. The paper ends with the presentation of the Core Program in progress, at the time of writing. An obvious conclusion is that without basic support, it is not possible to guarantee the functioning of the NIRDs and to cover the national research strategy evenly. This minimum basis also creates the conditions for international collaborations in the field, and involvement in European research programs, without forgetting the accomplishment of the external community obligations and the internal alignment in which Romania is taking part. NIMRD has been operating for over 50 years and continues to meet the increasingly complex requirements of environmental research. This is demonstrated by the experience of over 18 years of participation in the National Core Research-Development Programme."

Impact of rural and urban electricity access and economic growth in Ghana: Does line transmission losses matter?
Authors: Edward Amanfo Smart
Published: February 2023

This paper aimed to estimate the impact of rural and urban electricity access on Ghana’s economic growth between 1993 and 2018 by controlling for electricity transmission losses as a percentage of total electricity transmitted. The study used Stock-Watson Dynamic Ordinary Least Square (DOLS) to estimate the impact of electricity access and transmission losses on Ghana’s economic growth. The Engle-Granger, Phillips-Ouliaris, Park’s added variables and Hansen parameter instability cointegration methods were applied to test the long-run cointegration of the studied variables The results show that a 1% increase in electricity access was associated with a 0.073% decrease in economic growth. Additionally, a percentage increase in the rural electricity access rate was associated with a 0.527% increase in national income per capita. In contrast, urban population electricity access had no statistically significant association with economic growth in Ghana. The study suggests that improving population access to electricity infrastructure services while reducing power wastage through electricity transmission loss minimization is crucial to achieving the long-term impact of electric power on socio-economic development and environmental sustainability in Ghana, subject to other equally essential conditions.

Published: February 2023

An intrusion detection system, often known as IDS, is a piece of equipment or a piece of software that monitors a network or collection of devices in order to search for indications of possible intrusion. The frequency of cyber assaults has grown in recent years, and with it, the damage they do to society. The study of cyber security and the avoidance of cyber assaults, such as the use of intrusion detection as a defensive mechanism, is therefore needed. The internet services are widely used. Services based on computers, the internet, and other forms of technology are all considered part of the cyber world. The cyber world has advanced greatly thanks to new protocols and technologies. Cyber security is a major issue for every service that operates online. Network and host-based intrusion detection systems (NIDS/HIDS) are the backbones of any cyber security infrastructure. The NSL-KDD dataset is often used in algorithm research and verification and is widely employed in both the study and development of intrusion detection systems. In this study, we provide a neural network approach to intrusion detection system threat prediction. In this paper, the Python Spyder software is used for the simulation.

Amikor Budapest egyesítésének gondolata felmerült, elsősorban Buda és Pest szabad királyi városok nagy múltú, sűrűn beépített- és lakott, gazdaságilag is jelentős belső városrészeinek sorsát szerették volna szorosabban összekötni, amihez Óbuda mezőváros csatlakozása is eléggé kézenfekvőnek látszott. Később bizonyos megfontolások alapján egyes külterületek, vagy különleges helyzetű városrészek szabályozásáról is gondoskodtak – ilyen volt pl. a Margitsziget. Ugyanakkor Pestnek nagy kiterjedésű tartozékai is voltak, amelyek a lakosság számában, vagy az urbanizáció mértékében nem érhettek fel a belsőbb kerületekkel. Sokan így vélekedtek Kőbányáról is, holott az 1860-as évek végére itt már fontos előre lépések történtek a városiasodás felé, és az ide települt üzemek is jelentős gazdasági erőt képviseltek. Azonban ahhoz, hogy a honatyák Kőbányát komolyan vegyék, és végül tizedik kerületként csatlakozhasson a főváros területéhez, az itt érdekelt birtokosoknak, és gyártulajdonosoknak is össze kellett fogniuk. A következő írás erről számol be.

Authors: SINGH A K , KUMAR MUKESH , MITRA S
Published: February 2023

The study examines carbon and energy footprints of jute, kenaf, sunnhemp and flax fibre production systems. Energy productivity was lowest in flax fibre production as compared to other fibre crops. Flax fibre production consumed more chemical fertilizer, diesels, pesticides and seed energy in comparison to other fibre crops. The carbon footprints of the all fibres crops did not differ significantly and were in the order of 566, 520, 445 and 423 kg CO2-eq/tonne of fibre for jute, flax, kenaf and sunnhemp, respectively. The carbon based sustainability index for jute (2.27) and kenaf (2.07) were highest due to better carbon use efficiency. Sustainability index of flax was negative (-0.67) due to higher carbon emission. Fertilization and fibre processing contributed most to GHG emissions. Overall, the carbon footprint of bast fibres was 20â€“50% lower than that of synthetic/artificial fibres.

Published: February 2023

The medicinal plants are currently part of the sociocultural scenario in several countries, although their use has been described since the Egyptian peoples. Thus, in their most varied forms of use, medicinal plants play a fundamental role in people's lives, besides being used in the prospection of new molecules with biological action, and can be used as new therapeutic routes in disease treatments. Besides the recognition in popular medicine, research indicates that rosemary (Baccharis dracunculifolia) can be an ally for the treatment of numerous diseases due to its biological activities, such as antitumor, antibacterial, antiviral, antifungal, antiprotozoal, anti-inflammatory, antioxidant, immunomodulatory, and analgesic properties. Considering its high pharmacotherapeutic potential, it is important to analyze and compile knowledge about the bioactive compounds of rosemary and its biomedical applications. In this study, a bibliographical survey was carried out in order to collect data and information on the identification and description of the rosemary field bioactives, as well as their biological activities. Thus, some compounds stand out for their actions, such as p-coumaric, caffeic, chrysinic, 3,5-diprenyl-4-hydroxycinnamic, agathic, cuprésic, betuletol, 15-acetoxyisocuprésic, prenylated coumaric, 3,5 and 4,5-dicaffeoylquinic acids. These compounds have important biological actions, responsible for promising researches for innumerous treatments of diseases, with potential antitumor effect for several cell lines, promoting alterations in the cellular metabolism, in the respiratory chain, in the distribution and progression of the cell cycle and in the proliferation of tumor cells.
Scientific Evidence for the Use of Homeopathy for the Prevention and Treatment of COVID-19
Authors: Amaral Letícia Maria Silva , Pereira Neila de Paula
Published: February 2023

As of November 2, 2022, according to the World Health Organization (WHO), the total number of confirmed cases of COVID-19 in the world passed 620 million, and the total number of deaths due to the infection passed 6.5 million. Today, specific drugs against SARS-CoV-2 are still under study or starting to be marketed. In contrast, homeopathy is a long-established medical rationale, and is based on the patient's symptoms and individuality when choosing a medicine. Thus, the aim of this literature review was to gather available scientific evidence on the effectiveness of homeopathy in the prevention or treatment of COVID-19. We found 3 randomized clinical trial articles, 1 cohort study, and 7 descriptive observational studies. Of these, 73% repertorized the patients' symptoms and the prescription was individualized. The remaining articles were concerned with the analysis of homeopathic medicines as epidemic genius. Compiling the findings, it could be observed that homeopathy does indeed have a high beneficial adjuvant potential in the treatment of COVID-19 in mild, moderate and severe cases of the disease. However, more robust clinical trials and cohort studies are needed to investigate the prophylactic power of homeopathy in this case. Furthermore, Arsenicum album and Bryonia alba were the most prescribed drugs, with better results both in prevention and adjuvant treatment to allopathy, and therefore, are the ones suggested in this study as the epidemic genie.

This research explores the need for English for Academic Purposes (EAP) among Majmaah University students admitted into the Colleges of Medicine, Applied Medical Sciences, and Engineering. The purpose of this study was to persuade Majmaah University stakeholders that a needs analysis was the only objective method to inform the course design process. Data were collected from 180 participants using a questionnaire. The participants came from the Colleges of Medicine, Applied Medical Sciences, and Engineering. Data analysis revealed that there were significant differences in the students’ EAP skills. An interpretation of the results showed that these differences were attributable to the role of EAP in the academic activities in the three colleges. Based on the study findings, it was recommended that EAP courses should not be confined to the Deanship of Common First year. That is, colleges should consider adding more advanced courses to serve the students’ academic purposes at advanced levels. It was also recommended that a series of needs analyses should be conducted to update stakeholders’ perceptions of what constitutes a relevant EAP syllabus at advanced levels.

Sugarcane molasses are the largest produced waste in sugar mills; in the last harvesting cycle
2,178,131 tons were obtained and only 2.46% were used for transformation processes. Molasses has great potential to be the main feedstock in a biorefinery concept. Its composition rich in fermentable sugars and its availability are interesting features considered in this study. Through the Aspen Plus

software a multi-product biorefinery scenario was design and analyzed, technically and economically. The three main products considered were ethanol, lactic acid and succinic acid. The overall process consists of an initial stage of hydrolysis or inversion of the sucrose present in the molasses to reducing sugars followed by a specific dilution for fermentation of each of the products considered, as well as subsequent separation and purification operations.
Plant efficiencies conversions were 3.24 kg of molasses/L of ethanol, 3.08 kg of molasses/kg of lactic acid and 9.25 kg of molasses/kg of succinic acid. The economic assessment was positive for organic acids production. Ethanol production had a slightly worst economic performance compared to the other processes, but the proposed scenario managed to obtain a profitability index of 1.02. The expense recovery ratio of the whole biorefinery was 1.35 which means a surplus of 35% after the project investment has paid for itself. The biorefinery’s robustness in the economic aspect comes from organic acids production; meanwhile, the social and environmental impacts are from ethanol production.

Durante la última década ha habido un crecimiento exponencial de modelos de inteligencia artificial aplicados a los distintos campos del conocimiento incluida la psicología. Diversos estudios han utilizado dichos modelos con el objetivo de identificar precozmente potenciales riesgos. Sin embargo, pocos estudios enfocados en adolescentes han utilizado dichas técnicas. La presente revisión sistemática utilizó los pasos sugeridos por el modelo Prisma para identificar estudios que aplicaron técnicas de Machine Learning para identificar rasgos comportamentales en adolescentes. Al aplicar los criterios de inclusión y exclusión fueron identificados 5 estudios en las bases de datos PsycNET, PubMed, Scopus, Scielo, Web of Science y Science Direct. Los principales resultados muestran que los algoritmos de Machine learning principalmente utilizados de forma individual o combinada fueron regresión logística (n=4) y Support Vector Machine SVM (n=3) además de otros como Adaboost (n=1) Nested ten-fold crossvalidation (n=1), Random Forest (n=1), Artificial Neural Network ANN (n=1)  y Extreme gradient boosting XGB (n=1). Esta revisión resalta que la utilización de métodos de Machine learning proveen herramientas predictivas confiables tanto o más que los métodos estadísticos tradicionales. Por último, la presente revisión destaca la falta de estudios que utilicen dichas herramientas en el campo de la psicología principalmente en adolescentes.

Biophysical factors such as epicuticular wax,trichome density and leaf sheath thickness were analysed in the leaf sheath and laminae of plants treated with organic sources of nutrients. The results revealed that wax content and trichome density increased in plants as the age of the plant advanced. The difference in epicuticular wax content was significant among treatments. At 45 DAT, the treatments viz., FYM, biofertilizers, lignite fly ash and neem cake as basal and in splits and FYM plus neem cake as basal and in splits recorded maximum trichome density of 49.33, 49.67, 49.67 and 48.34 / cm2 leaf respectively. The same trend was also noticed on 60 DAT. On 60 DAT, the combination of FYM, biofertilizers and neem cake as basal was significantly superior in having maximum wax content (23.67 mg/g) which was on par with the combination of FYM, biofertilizers, lignite fly ash and neem cake as basal (22.00 mg / g). Treatments showed significant difference in leaf sheath thickness on 60 DAT. But the difference was not significant on 30 DAT and it varied from 0.24 to 0.35 mg/mm2 and the leaf sheath thickness was maximum in the combination of FYM, biofertilizers, lignite fly ash and neem cake in splits which recorded 0.58 mg/mm2.
Sistema adaptativo para teleoperação de uma base móvel através de reconhecimento gestual
Authors: Martinelli Dieisson , Fabro João Alberto , Oliveira André Schneider de
Published: February 2023

Este artigo apresenta o desenvolvimento de um sistema adaptativo para teleoperação de uma base móvel acoplada a um braço robótico com três graus de liberdade, através de captura de gestos apartir de uma câmera RGB. Este projeto utiliza o pipeline holístico do framework MediaPipe para capturar pontos 2D do corpo do operador através de imagens RGB e dois algoritmos são desenvolvidos através deste framework. O primeiro algoritmo é responsável por extrair características do operador que realiza o movimento solicitado para executar um determinado processo de movimento. O segundo algoritmo é responsável por utilizar os dados coletados do corpo do operador no momento do processo e identificar, por meio de classificação, a movimentação solicitada pelo operador. Após a classificação do movimento, é calculada a posição do ponto chave, que, por meio de técnicas propostas pelo algoritmo deste trabalho, resulta em um valor de 0 a 100 de ativação do movimento requerido. Este valor passa por um sistema de controle fuzzy, que emitirá o movimento do robô. Os testes são realizados com 20 operadores voluntários com o objetivo de seguir uma trajetória e recolher/entregar um objeto.

Controlar os movimentos de robôs projetados para atuar com ferramentas e em ambientes feitos para humanos tem se mostrado uma tarefa desafiadora. Essa dificuldade tem estimulado a investigação de novos métodos de controle que independam do modelo dinâmico dos robôs. A robô humanoide Marta, projetada e construída pelo grupo de trabalho, apresenta características construtivas diferenciadas: pés pequenos, pontas dos pés articuladas e junta esférica na cintura. Tendo em vista a arquitetura deste robô, o presente trabalho apresenta um controlador livre de modelo para a marcha de robôs humanoides composto por dois blocos desacoplados: i) um controlador clássico para a articulação esférica da cintura que foca na estabilidade do robô e ii) um controlador de trajetória para marcha baseada na Série Truncada de Fourier com parâmetros sintonizados por algoritmo genético. Os resultados mostram que a arquitetura mecânica e a estratégia de controle desacoplado têm juntas potencial para conferir robustez adicional ao caminhar de robôs bípedes em relação às técnicas convencionais.

Published: February 2023

Este artigo apresenta um framework multi domínio e multi perspectiva para localização de robôs submarinos, que não requer nenhuma informação do Sistema de Posicionamento Global (GPS). O método de localização proposto usa imagens aéreas coloridas e imagens acústicas subaquáticas para estimar a posição do robô. O método identifica a correlação entre imagens de domínios distintos, dada pelo casamento de imagens adquiridas em ambientes parcialmente estruturados com características compartilhadas. A validação do método proposto é feita usando um conjunto de dados real, que foi adquirido por um veículo submarino em uma marina. Além disso, foi realizada a comparação com Dead Reckoning e um método baseado em aprendizado. Os resultados experimentais apresentam a viabilidade do método proposto e seus avanços em relação ao estado da arte.

O OurGrid é um middleware que oferece suporte à execução de aplicações nos recursos disponíveis em um grid. Nesta ferramenta, o controle e o escalonamento das aplicações são feitos por um nó central, o que o torna um elemento crítico do sistema, em situação de falha. Visando diminuir a perda de computação causada por colapso no nó central do OurGrid, este trabalho apresenta uma implementação de mecanismo de checkpointing e respectiva recuperação. O impacto do mecanismo no desempenho do escalonador é avaliado em cenários com características distintas.
Using Dynamic Analysis Of Java Bytecode For Evolutionary Object-Oriented Unit Testing
Authors: Ribeiro José Carlos Bregieiro , Vega Francisco Fernández de , Zenha-Rela Mário
Published: February 2023

The focus of this paper is on presenting a methodology for generating and optimizing test data by employing evolutionary search techniques, with basis on the information provided by the analysis and interpretation of Java bytecode and on the dynamic execution of the instrumented test object. The main reason to work at the bytecode level is that even when the source code is unavailable, structural testing requirements can still be derived and used to assess the quality of a given test set and to guide the evolutionary search towards reaching specific test goals. Java bytecode retains enough high-level information about the original source code for an underlying model for program representation to be built. The observations required to select or generate test data are obtained by employing dynamic analysis techniques – i.e. by instrumenting, tracing and analysing Java bytecode.
