Various Plant Sources - A Brief Review
Authors: Saidul Sk , Das Susmita , Hoda Muddasarul
Published: May 2023

Resveratrol is a stilbene class of phenolic phytochemical that has a wide range of utilization in
several industries, including pharmaceutical, food and cosmetic industries. It is available in several plants,
including grapes, berries, and peanuts. Major focus of research regarding resveratrol has been its therapeutic potential against major diseases, including cardiovascular, inflammatory, cancer, microbial and
age-related diseases. However, its extraction methods have not been of much discussion. In this review,
nonconventional methods, including supercritical fluid extraction, subcritical water extraction, microwave-assisted extraction, ultrasound assisted extraction, and high hydrostatic pressure extraction have
been discussed in contrast to widely implemented conventional extraction methods. Nonconventional
methods are considerably advanced over conventional methods. In this review, the efficiency of various
nonconventional methods via optimization of their extraction parameters, such as the effects of modifiers,
solvents, pressure, temperature, and extraction time, have been evaluated. Improvised extraction methods
may result in cost-effective isolation of resveratrol.
Improving Intelligence Metrics using Frequency Domain Convolutions for
Improving Bug Prediction
Authors: Mishra Anurag , Sharma Ashish
Published: May 2023

Background:

The novelty of the work lies in the formulation of these frequency-based
generators, which reflects the lowest level of information loss in the intermediate calculations. The
core idea behind the approach presented in this work is that a module with complex logic involved
may have more probability of bugs. Software defect prediction is the area of research that enables
the development and operations team to have the probability of bug proneness of the software. Many
researchers have deployed multiple variations of machine learning and deep learning algorithms to
achieve better accuracy and more insights into predictions.

Objective:

To prevent this fractional data loss from different derived metrics generations, a few optimal
transformational engines capable of carrying forward formulations based on lossless computations
have been deployed.

Methods:

A model Sodprhym has been developed to model refined metrics. Then, using some classical
machine learning algorithms, accuracy measures have been observed and compared with the
recently published results, which used the same datasets and prediction techniques.

Results:

The teams could establish watchdogs thanks to the automated detection, but it also gave
them time to reflect on any potentially troublesome modules. For quality assurance teams, it has
therefore become a crucial step. Software defect prediction looks forward to evaluating error-prone
modules likely to contain bugs.

Conclusion:

Prior information can definitely align the teams with deploying more and more quality
assurance checks on predicted modules. Software metrics are the most important
component for defect prediction if we consider the different underlying aspects that define the defective
module. Later we deployed our refined approach in which we targeted the metrics to be considered.

Published: May 2023

This study aims to evaluate the combination of city branding and ecocity in Indonesia and critically examine the opportunities and challenges of developing both concepts. The background of this study was the increasing attention to the development of sustainable cities in Indonesia and the importance of city branding in enhancing a city's competitiveness. However, there is concern that city branding may overlook environmental sustainability aspects, which has led to the development of the ecocity concept as an alternative to improving the city's sustainability. The research method used in this study was a literature review. This literature review uses a systematic literature review approach with a narrative review method. The literature database used Google Scholar, CrossRef data, and Scopus data from 2010-2023. The results showed that developing a combination of City Branding and Ecocity has several opportunities and challenges that must be faced in Indonesia. The opportunities that arise are improving the positive image of cities in Indonesia, improving the quality of the environment in densely populated cities, and enhancing a city's competitiveness in investment and tourism. However, the challenges include limitations in resources, both financially and in terms of human resources, and obstacles in implementing sustainable policies and regulations. Nevertheless, Indonesia has significant opportunities to combine the concepts of City Branding and Ecocity.

Authors: van der Schyff Emma L , Ridout Brad , Amon Krestina L , Forsyth Rowena , Campbell Andrew J
Published: May 2023

Digital mental health services are becoming increasingly valuable for addressing the global public health burden of mental ill-health. There is significant demand for scalable and effective web-based mental health services. Artificial intelligence (AI) has the potential to improve mental health through the deployment of chatbots. These chatbots can provide round-the-clock support and triage individuals who are reluctant to access traditional health care due to stigma. The aim of this viewpoint paper is to consider the feasibility of AI-powered platforms to support mental well-being. The Leora model is considered a model with the potential to provide mental health support. Leora is a conversational agent that uses AI to engage in conversations with users about their mental health and provide support for minimal-to-mild symptoms of anxiety and depression. The tool is designed to be accessible, personalized, and discreet, offering strategies for promoting well-being and acting as a web-based self-care coach. Across all AI-powered mental health services, there are several challenges in the ethical development and deployment of AI in mental health treatment, including trust and transparency, bias and health inequity, and the potential for negative consequences. To ensure the effective and ethical use of AI in mental health care, researchers must carefully consider these challenges and engage with key stakeholders to provide high-quality mental health support. Validation of the Leora platform through rigorous user testing will be the next step in ensuring the model is effective.

The integration of large language models (LLMs), such as those in the Generative Pre-trained Transformers (GPT) series, into medical education has the potential to transform learning experiences for students and elevate their knowledge, skills, and competence. Drawing on a wealth of professional and academic experience, we propose that LLMs hold promise for revolutionizing medical curriculum development, teaching methodologies, personalized study plans and learning materials, student assessments, and more. However, we also critically examine the challenges that such integration might pose by addressing issues of algorithmic bias, overreliance, plagiarism, misinformation, inequity, privacy, and copyright concerns in medical education. As we navigate the shift from an information-driven educational paradigm to an artificial intelligence (AI)–driven educational paradigm, we argue that it is paramount to understand both the potential and the pitfalls of LLMs in medical education. This paper thus offers our perspective on the opportunities and challenges of using LLMs in this context. We believe that the insights gleaned from this analysis will serve as a foundation for future recommendations and best practices in the field, fostering the responsible and effective use of AI technologies in medical education.

Published: May 2023

This paper offers a historical and anthropological explanation for the unwillingness demonstrated by the Mapuche people from the free lands to accept the Christian model of matrimony in the 17th century. We argue that indigenous responses and attitudes toward the sacrament were conditioned by their own notions of family, the social implications of marital union and the adaptation of Christian marriage for indigenous evangelization and peaceful relations between the parties.

Published: May 2023

Abstract: All humans mainly rely on cultivation for food. Agriculture acts as a backbone for many countries’ economies One of the key factors of economic growth in Ghana is agriculture. It is believed that the agriculture sector forms a vital part of building a resilient economy. Food is an essential component of our daily existence and a significant portion of it is supplied by farms. The hard work of farmers who grow and cultivate crops sustains countless lives across the country and provides them with a source of income. Unfortunately, due to intermediaries involved in the selling of their final products, farmers often struggle to make a profit and are forced to live in poverty. Through this project, we will be able to connect farmers directly to the customer so that direct dealing of products can be accomplished. This will end in a big decrease in the prices of the products currently available within the market because the profit will directly reach the farmers pocket. It will also provide personalized views for farmers, suppliers, and admin by their different logins by that handling of the webpage will be comfortable.

Authors: Ninik Anisah
Published: May 2023

The Covid-19 pandemic has reduced economic growth in West Java, including investment growth explained by the decline in economic growth in the Gross Fixed Capital Formation component. Moreover, the primary measure that illustrates the economic region shows how much monetary value is formed to Gross Regional Domestic Product. This study looks at the investment conditions of Foreign Direct Investment, Domestic Direct Investment, and Government Capital Expenditures before and during the Covid-19 pandemic and the effect of these investments on the Regional Economic. The multiple regression analysis methods use the data to cross-section with individual districts and cities in West Java Province and the three investment variables. The analysis results explain that the Covid-19 pandemic has reduced Foreign Direct Investment and Government Capital Expenditure, on the other hand, increased Domestic Direct Investment. This increase in Domestic Direct Investment is related to the new businesses that are strongly related to the handling of the Covid-19 pandemic. Domestic Direct Investment and Government Capital Expenditure are still being felt on the region's economy before and during the Covid-19 pandemic, but Foreign Direct Investment has decreased.  Before the Covid-19 pandemic, the real impact of Foreign Direct Investment came from the first and second years after investment. In contrast, during the Covid-19 pandemic, the real impact came from three years after invested Foreign Direct Investment.

Authors: Rai Abyan
Published: May 2023

The agricultural sector plays an essential role in the economy of a country. This critical role cannot be separated from the main component of the farm sector, namely, farmers. To support economic growth and poverty alleviation through the agricultural industry, the welfare of farmers must be a concern. This study aims to analyze the effect of the income of farmers and farm laborers on agricultural economic growth. The method used is ECM with 24 quarterly data observations. The price index received by farmers approximates farmers' incomes, farm laborers' incomes are approximated by the daily real wages of farm laborers, and agricultural economic growth is approximated by the real GRDP of the agricultural sector. The results showed that the income of farmers and farm laborers during the research period had a positive trend. In the long-term and short-term equation, the payment of farmers and farm laborers has a significant positive effect on the economic growth of the agricultural sector. An increase in the income of farmers and farm laborers also followed the increase in agricultural economic development. These results can be used as a reference for the government to make policies to increase the income of farmers and farm laborers.

Political Power of Digital Transnational Corporations: To the Problem of Research
Authors: Zaytsev Stanislav Y.
Published: May 2023

The spread of digital technologies in the everyday life of citizens (social networks, streaming video, messengers) and in the socio-political sphere («smart city», e-government) has led to an increase in the power of transnational corporations specializing in the development and launch of these products and services on the market - digital TNCs. Thanks to the increase in financial power, such firms became actors that were able to influence the political sphere, for example, by influencing the views and attitudes of voters during electoral campaigns or mass protests, collecting confidential user data and providing it to intelligence agencies, etc. The purpose of the article is to characterize digital TNCs as actors with political power. To analyze the activities of digital TNCs at the present stage, the author applied the approach of Marius Busemeyer and Kathleen Thelen, who proposed to consider business representatives as actors with instrumental, structural and institutional sources of power. It is concluded that at the present stage, digital TNCs implement an instrumental and structural type of power, and also have the potential to implement institutional power, which involves the replacement of a number of government functions.

Published: May 2023

This study assessed user satisfaction with e-policing in Nigeria using a quantitative approach. The need for the study was necessitated due to insufficient empirical studies on the impact of information and communications technology on security in Nigeria, particularly the police. This study in particular examined the influence of the quality of the e-police information technology (service quality, system quality and information quality) on user satisfaction, while perceived usefulness was used as a mediator in the relationship. Data was gathered through a structured survey administered to Nigerians online, emphasis was given to citizens with earlier contact with the police online either through the web or social media. The collected data was analyzed using PLS-SEM and SmartPLS 4 as the analytical software. the result showed that all hypotheses were significant. In particular, all the quality dimensions were positive and significant with perceived usefulness and user satisfaction, while perceived usefulness partially mediate the relationships between the quality dimensions and user satisfaction with e-police. The result implies that the degree of satisfaction that users have with e-government services is connected with the level of perceived usefulness of those services. Therefore, it is noted that perceived usefulness is a crucial factor in determining whether or not people will adopt e-policing and that this factor has a substantial bearing on the degree to which users are satisfied with the system.
The Mobilization State as an Essential Characteristic of Russian Civilization: The Initial Stage of Formation
Authors: Ilinskaya Svetlana G.
Published: May 2023

The local-civilizational approach, shared by the author of the article, assumes the existence of various “cultural-historical types” (In the words of his pioneer N.Ya. Danilevsky), which have different “logics of culture” and types of “collective cognitive unconscious” (according to A.V. Smirnov). These qualitative differences formed under the influence of special climatic and geographical conditions (habitat), as well as historical Challenges and the Answers found to them (according to A. Toynbee), found their expression in political and economic institutions, algorithms for responding to crises. One of such institutions for the Russian civilization was the phenomenon of the mobilization state, born as a spontaneous response to a historical challenge, mentally and institutionally fixed later (as a tested means of response). In this article, using the method of historical reconstruction, the author stops at the initial stage of the formation of this very specific manifestation of traditional Russian collectivism.
Community Tradition in Pre-Romanov Russia
Authors: Yahshiyan Oleg Y.
Published: May 2023

The understanding of the basic laws of the political history of Russia will be obviously incomplete without a scientific understanding of the role of the community (agricultural, rural, peasant) in the development of national statehood at each appropriate stage. The unity and continuity of the national history up to and including the Soviet period was ensured by the reproduction of the community in its various concrete historical forms. The way out of the most significant points of bifurcation in the history of Russia is inextricably linked with the communal tradition: the revival of the national statehood both after the overthrow of the Horde yoke, and during the overcoming of the Troubles of the beginning of the XVII century. The article is devoted to the consideration of community tradition as a long-term factor in the history of national statehood. The markers of the civilizational specificity of Russia associated with the community (attitude to private property, neighborly character) are emphasized. The view of the politogenesis of the Eastern Slavs and the statehood of the lands of pre-Mongol Russia as the formation and development of a system of subordinate communities is consistently substantiated. The inclusion of the estate self-government of the tyagly posadsky and volost worlds in the system of state administration of Moscow Russia as a grassroots administration is revealed.

Authors: Fedorenko Konstantin A. , Miroshnichenko Inna V.
Published: May 2023

The article reveals essential characteristics and results of institutional foundations evolution of the Russian Federation public policy in the field of volunteering. The authors identify four stages in formation and development of institutional framework for regulation of the institution of volunteerism: the stage of implementation of Western norms and experiences (1990-1995); the stage of creating of legal norms for regulation of volunteering and orientation of volunteerism to the performance of significant social functions (1995-2005); the stage of integrating volunteering into long-term state development programs and expanding the practice of volunteer activity (2006-2018); the stage of consolidating national priorities in the field of volunteerism and formalizing it as a unified system of civic activities and intersectoral interaction (2018 - to date). The authors conclude that a national model for development of volunteerism has been already created in modern Russia. This model integrates ideological, legal, social, political, managerial and economic components; ensures close interaction between volunteer structures and public authorities. Prospects for institutional development of volunteerism are associated with formalization and generalization of practices that take shape in conditions of socio-political crises based on Russian civic identity. They are focused on mass participation of citizens of various ages, motivated by humanistic and civic motives.

The Wireless Sensor Network technologies has great advantage that provide us with cheap solution to deal with telecommunication infrastructure problem that don’t exist in extreme and isolated area. However, the biggest problem exist within wireless sensor network was WSN node limited power. In this paper we try to provide battery less power sources for Wireless Sensor Network Node using Redox method. Using 9 combinations of electrodes circuits, it can provide 6.53 volt and turn on Arduino Mini Pro microcontroller. However, the second it turns on Arduino Mini Pro the voltage drops to 1.73 Volts. Hence this energy harvester can provide power to the Arduino Mini Pro microcontroller with unstable power supply.

The focus of Indonesia's G20 Presidency lies on three main pillars, one of them is transition to sustainable energy. The development of these conditions forced PLN (State Electricity Company in Indonesia) to innovate by participating in implementing the latest digitalization technology in distribution electrical energy to customers, one way to do this is by implementing the smart grid concept, which is digital substation technology, is considered capable to response the challenges of digitizing the electricity system in the energy distribution sector. Digital substation technology in Indonesia is still in development stage and there are only six pilot projects in scattered locations, hence in-depth research is needed regarding equipment requirements and the amount of investment needed by PLN to build digital substations, especially the plan for implementing digital substations in Sulawesi. One of methods for developing digital substations in Indonesia is upgrading conventional into digital substation. Research is conducted by studying and observing the existing digital substation in Indonesia. Afterwards in this paper will be explained how to upgrade and what materials, or equipment that must be equipped to upgrading conventional substations. Then, what is the actual value of the investment needed by PLN to build or upgrading into a digital substation in Indonesia, especially in Sulawesi. Furthermore, whether the upgrading plans can be declared financially feasible.

Liver cancer represents the most common neoplasm in the liver. Among the
different existing subtypes of hepatocellular carcinoma, the
fibrolamellar variant represents less than 5% of liver carcinomas. We
present the case of a 25-year-old male with fibrolamellar
hepatocarcinoma managed with left hepatectomy with a pathological report
of negative margins, but with recurrence within the right hepatic duct.

The Santos Basin is the largest Brazilian offshore basin and is currently the main hydrocarbon producer in the country, comprising an area of approximately 350,000 km2 . Given the importance of understanding and analyzing its carbonate reservoirs (Itapema and Barra Velha formations), a tectono-stratigraphic model of the Wildcat Prospect was created. This area is in the Outer High of the Santos Basin, main region of the presalt carbonate reservoirs in the Santos Basin. The 3D model is focused on the presalt reservoir and the understanding of the main tectonic structures in this area and their relationships that conditioned the carbonate successions deposition. Four steps were followed to analyze the depositional and structural framework and build the tectono-stratigraphic model: (i) generation and analysis of seismic attributes to identify and characterize seismic terminations (erosional truncation, toplap, and onlap), seismic facies (debris, build-ups, platform carbonates, and bottom lake), and assist in the tectono-stratigraphic analysis; (ii) seismic interpretation of horizons and faults, which were used as input for the modeling as surfaces and fault planes, creating compartmentalized blocks; (iii) construction of the stratigraphic column to classify the succession of tectonic and sedimentary events; and (iv) the construction of the model. This study helps to understand the depositional and structural evolution of the presalt and provides a three-dimensional understanding of the influence of faults on the reservoir geometry. Faults influenced the eroded zone observed in the Upper Barra Velha Formation, since this erosion occurs mainly at the edges of the large-throw faults. The build-up seismic facies, the main reservoirs in the study area, have a trend NW-SE to N-S following the large-throw faults.

Introduction/Objective. Radical prostatectomy (RP) is a treatment option with high curative potential in patients with prostate cancer of moderate-risk. The aim of the study is to assess perioperative results of laparoscopic RP (LRP) and open retropubic RP (ORRP). Methods. From 2016 to 2020, a total of 244 patients undergone RP, as follow: 145 patients LRP and 99 patients ORRP. Demographic data, preoperative parameters, perioperative and pathological outcomes were analyzed and compared among LRP and ORRP groups. Results. In regard to demographic data and preoperative parameters (BMI, mean age, median pretreatment prostate-specific antigen, clinical stage and Gleason score from biopsy), there are no differences between the observed groups. Patients from ORRP group had significantly shorter operative time (p < 0.05). Patients from LRP group had major advantages in regard to estimated blood loss (EBL) (550 ml for LRP vs. 1450 ml for ORRP), hospitalization time (six days for LRP vs. nine days for ORRP), catheter removal (6.5 days for LRP vs. 12 days for ORRP), overall complication rates (29% for LRP vs. 48.4% for ORRP) and blood transfusion rates (22.7% for LRP and 37.4% for ORRP). Conclusion. Both LRP and ORRP provide favorable operative results in terms of efficacy, safety and oncologic outcome. However, patients undergoing LRP were more likely to have less EBL, shorter length of hospital stay, earlier catheter removal and lower rates of overall perioperative complications.

Background/Aim. The ability to effectively and consistently penetrate dentinal tubules is considered a favorable factor for the evaluation of root canal sealers (RCSs). The aim of the study was to assess the penetration depth into dentinal tubules of three RCSs combined with four obturation techniques. Methods. The mesial canals of 66 extracted human mandibular molars were endodontically prepared and randomly allocated into 12 experimental groups depending on the RCS type used (AH Plus?, EndoREZ?, Sealapex?) as well as the obturation technique applied [cold lateral compaction, cone-fit, carrier-based (with heated gutta-percha), warm vertical compaction]. Using scanning electron microscopy, transversal root cross-sections were analyzed, and the maximum depth of RCS penetration was measured (396 sections, in total, corresponded to the apical, middle, and coronary third). Results. Group AH Plus?/warm vertical compaction yielded the highest penetration depth ? 1,165 ?m, followed by EndoREZ?/cone-fit ? 1,154 ?m; the lowest depth was measured for EndoREZ?/warm vertical compaction ? 502 ?m. The mean value of the maximum penetration depth of RCS yielded 1,204 ?m in the coronary thirds, 1,005 ?m in the middle thirds, and 770 ?m in the apical thirds. The AH Plus? RCS penetrated deeper into dentinal tubules when the obturation techniques with heated gutta-percha were applied, while the opposite findings were obtained for the EndoREZ? RCS. Conclusion. According to our research, the RCS penetration depth appears to be influenced by the RCS type used, as well as the obturation technique applied.
