Published: June 2024

Photodynamic inactivation (PDI) is a technique to inhibit microbial biofilm growth through the toxicity of Reactive Oxygen Species (ROS) compounds. ROS can be attack membrane, lipids, DNA and nucleic acid then initiate cell necrosis. This study aims to analyze the potential of red and blue LEDs to activating silver nanoparticles (AgNPs) to produce significant amounts of ROS that are believed to be toxic and lethal to Candida albicans biofilm cells. The effectiveness of the treatment in this study was evaluated through cell viability represented by Optical Density values and malondialdehyde levels. There were 4 treatment groups used as samples, namely the control group, the photosensitizer group, the light group, and the combination group of light with photosensitizer. The duration of light exposure ranged from 2 to 10 min with a power of 100 MW. The biofilm staining done to detection some indicator as an impact of photodynamic against mortality and survive cell with 2 dyes are XTT assay as cell viability values and the Thiobarbituric Acid Reactive Substances assay for malondialdehyde levels. The results showed that photoinactivation of Candida albicans biofilm with the lowest viability occurred in the treatment group of the combination of blue light with AgNPs with an irradiation duration of 10 min, namely 0.076 ± 0.005 and the treatment group of the combination of red light with AgNPs with an irradiation duration of 10 min, namely 0.131 ± 0.021. The data resulted in an inactivation rate of 94.68 ± 0.55 % for blue light and 90.98 ± 0.02 % for red light. The malondialdehyde levels were 1.563 nmol/mL for blue light and 1.514 nmol/mL for red light. The comparison of blue light treatment with red light is based on penetration in the cell, where blue light has low penetration but high energy which gives more opportunities to produce ROS at the triplet level. The combination of blue LED spectrum with AgNPs is highly effective in inactivating the metabolic activity of pathogenic microbial cells.
HIGHLIGHTS
Candida albicans biofilm is very rigid and has strong potential as a chronic infection. The research focuses on the application of photodynamic inactivation with LED light and antimicrobial AgNPs. Identification of the results with XTT assay 94.65 % inhibition and TBARS assay at MDA level of 1,864 nmol/mL.
GRAPHICAL ABSTRACT
Autonomia e intersubjetividade como reconhecimento dos indivíduos em Honneth
Authors: Pereira Fernando Schell
Published: June 2024

A exposição que segue terá atenção à subjetividade na influência da agência moral, revelando que a construção do ethos gira viciosamente se o agente não intervir ciente de sua autonomia, a qual Axel Honneth e outros filósofos apontam na tradição. A intersecção do processo terapêutico e dialético de Honneth com a preocupação kantiana da instrumentalização do ethos leva ao exercício de atravessar a atual conjuntura utilitarista nos cuidados com a vida humana e não humana. Ao demonstrar a intersubjetividade, torna-se relevante para o bem-estar coletivo e a individuação aumenta as responsabilidades. O ethos no coletivo deve ser tensionado para a autonomia da subjetividade. Por fim, versa sobre a linguagem e suas perspectivas de mundos éticos, com breve relevância às virtudes como instrumento dos agentes para não perder o foco do exame da subjetividade na construção da moral, assim como não assumir projeções na construção de valores.

La renovación conceptual de la antropología de los pueblos indígenas de México es una labor que ha sido anunciada demasiadas veces, pero emprendida muchas menos de las necesarias; al grado que ha llegado al punto en el que ya no son suficientes los llamamientos teóricos para introducir en nuestra tradición antropológica paradigmas como la antropología de las ontologías y la cosmopolítica, ni tampoco basta la elaboración de artículos en los que dichas ideas jueguen un papel, sino que resulta indispensable la elaboración, desde cero, de monografías etnográficas que den sustento real a dichos llamados y pongan bastamente en escena dichas ideas, ya sea para sustentarlas, transformarlas o cuestionarlas a través de la experiencia de campo, fundamento inevitable de toda antropología seria.

Authors: Campble Price Ernesto Ariel
Published: June 2024

La Administración Aduanera en Panamá y su relación con el Sistema Internacional de Comercio, es un tema de obligatorio análisis, dado el grado de incertidumbre que existe en Panamá y otros países de la región, en lo referente a las relaciones comerciales con países como China y otras potencias comerciales que amenazan invadir los mercados americanos. Para tales fines, analizamos la administración aduanera en Panamá y su relación con los registros de comercio exterior a través del “Sistema Especial de Comercio y las estadísticas de la década pasada, presentadas por el Instituto Nacional de Estadística y Censo (INEC) de la Contraloría General de la República de Panamá. Recurrimos al organismo internacional regente de la administración de aduanas; La Organización Mundial de Aduanas (OMA), organismo intergubernamental independiente cuya misión es incrementar la eficiencia de las administraciones de aduanas. La selección de la muestra bibliográfica se basó en una perspectiva pragmática para atender las cuestiones aduanales a nivel nacional e internacional establecidos en la lista de control relativa a las medidas de comprobación del valor que la Administración de Aduanas de un país de importación debe tomar antes de solicitar información a la Administración de Aduanas del país de exportación. Finalmente, evidenciamos con esta investigación que, si bien es cierto las negociaciones del GATT, las nuevas políticas de la OMA y, posteriormente, OMC, los aranceles de los países desarrollados han bajado ininterrumpidamente, es de suma importancia establecer acuerdos que permitan una estandarización en los procesos de la administración aduanera en el comercio internacional.

Published: June 2024

Pipeline leaks are a frequent occurrence in oil and gas infrastructure worldwide. Though leak detection systems are expected to be installed on all pipelines in the near future, relying on human efforts to physically monitor these pipelines is and will continue to be challenging. Though today's leak detection techniques are not able to completely stop leaks from occurring or to detect most leaks, they are essential in lessening their effects. Despite recent developments toward solving this problem, the solution still falls short of expectations. This research presents an approach to pipeline leak detection by leveraging on the exceptional abilities of Convolutional Neural Network (CNN) and Internet of Things (IoT).  A comprehensive dataset on oil and pipeline leakage is collected, and the CNN model is developed and trained with the collected dataset. Thereafter, the trained model is integrated into the monitoring system to provide notifications of leaks. The model is adaptable and scalable and its performance, as evaluated, shows an improvement over existing systems with an accuracy of 97% hence well suited for deployment in various pipeline networks for the overall improvement of safety environment in the oil and gas sector.

Published: June 2024

Indonesia, as a country predominantly surrounded by the sea, holds significant potential in marine resources, fisheries, and other maritime fields. However, there is still a lack of awareness and understanding among the Indonesian population regarding these maritime aspects. Currently, there are various media and information sources related to this topic, ranging from websites and applications to supporting information systems. Nevertheless, users often struggle to find and comprehend this information easily and comprehensively. Existing information systems tend to be fragmented or operate independently, leaving many laypeople unable to fully optimize the existing potential. To address this, researchers aim to identify and model a comprehensive and integrated information system focused on marine and other maritime resources, known as SI-LAUT The research method employed in this study consists of literature review, stakeholder identification based on the Penta-Helix model, analysis of the existing system, and gap analysis in comparison to previous research that focused on the implementation of other maritime and marine information systems. The results of this research consists of a recommendation for an information system development model that can assist various stakeholders based on the Penta-Helix Model. These stakeholders include government bodies, entrepreneurs, academics, as well as the general public or other communities. The goal is to optimize the management and utilization of Indonesia’s marine resources, ultimately positioning it as a global maritime powerhouse.

Authors: Oluwatosin Ilori  , Nelly Tochi Nwosu  , Henry Nwapali Ndidi Naiho
Published: June 2024

This concept paper examines the integration of Agile methodologies into IT audit processes to enhance effectiveness and efficiency. In today's dynamic and rapidly evolving technological landscape, traditional audit approaches often struggle to keep pace with the speed and complexity of IT environments. Agile methodologies, originating from software development, offer a flexible and iterative framework that can revolutionize IT audit practices. The paper begins by highlighting the limitations of traditional audit methodologies in addressing the challenges posed by modern IT systems. It then introduces Agile principles and practices, explaining how they can be adapted and applied within the context of IT audits. By embracing Agile, auditors can shift from rigid, linear audit processes to iterative, collaborative approaches that promote adaptability, responsiveness, and continuous improvement. Key components of Agile methodologies, such as sprints, stand-up meetings, and user stories, are explored in the context of IT audits, demonstrating how they can streamline audit planning, execution, and reporting. The paper also discusses the cultural shift required for successful Agile adoption within audit teams and organizations, emphasizing the importance of communication, collaboration, and a mindset focused on delivering value. Through case studies and real-world examples, the paper illustrates the tangible benefits of applying Agile methodologies to IT audits. These include increased audit coverage, faster identification of risks and issues, enhanced stakeholder engagement, and improved alignment with business objectives. Additionally, Agile practices enable auditors to adapt to changing priorities and emerging risks more effectively, ensuring audit activities remain relevant and impactful in dynamic environments. Despite its potential benefits, Agile adoption in IT audits presents challenges such as cultural resistance, skill gaps, and the need for organizational support and buy-in. The paper addresses these challenges and proposes strategies for overcoming them, including training and development initiatives, stakeholder engagement, and pilot projects. In conclusion, the paper advocates for the integration of Agile methodologies into IT audit practices as a means to enhance effectiveness, responsiveness, and value delivery. By embracing Agile principles and practices, auditors can better meet the demands of today's digital landscape, driving continuous improvement and innovation in audit processes. In this concept paper, I analyze how the adoption of Agile methodologies, particularly Scrum, can revolutionize IT audits. I explore how these methodologies improve collaboration, adaptability, and overall audit effectiveness, supported by practical examples and insights from my professional experience.

LamaH-Ice: LArge-SaMple DAta for Hydrology and Environmental Sciences for Iceland
Authors: Helgason Hordur Bragi , Nijssen Bart
Published: June 2024

Abstract. Access to mountainous regions for monitoring streamflow, snow and glaciers is often difficult, and many rivers are thus not gauged and hydrological measurements are limited. Consequently, cold-region watersheds, particularly heavily glacierized ones, are poorly represented in large-sample hydrology (LSH) datasets. We present a new LSH dataset for Iceland, termed LamaH-Ice (LArge-SaMple DAta for Hydrology and Environmental Sciences for Iceland). Glaciers and ice caps cover about 10 % of Iceland and, while streamflow has been measured for several decades, these measurements have not previously been published in a consistent manner. The dataset provides daily and hourly hydrometeorological time series and catchment characteristics for 107 river basins in Iceland, covering an area of almost 46 000 km2 (45 % of Iceland's area), with catchment sizes ranging from 4 to 7500 km2. LamaH-Ice conforms to the structure of existing LSH datasets and includes most variables contained in these datasets as well as additional information relevant to cold-region hydrology, e.g., time series of snow cover, glacier mass balance and albedo. LamaH-Ice also includes dynamic catchment characteristics to account for changes in land cover, vegetation and glacier extent. A large majority of the watersheds in LamaH-Ice are not subject to human activities, such as diversions and flow regulations. Streamflow measurements under natural flow conditions are highly valuable to hydrologists seeking to model and comprehend the natural hydrological cycle or estimate climate change trends. The LamaH-Ice dataset (Helgason and Nijssen, 2024) is intended for the research community to improve the understanding of hydrology in cold-region environments. LamaH-Ice is publicly available on HydroShare at https://doi.org/10.4211/hs.86117a5f36cc4b7c90a5d54e18161c91 (Helgason and Nijssen, 2024).
2021 Alaska Earthquake: entropy approach to its precursors and aftershock regimes
Authors: Vogel Eugenio E. , Pastén Denisse , Saravia Gonzalo , Aguilera Michel , Posadas Antonio
Published: June 2024

Abstract. For the first time, an entropy analysis has been made in Alaska, a seismic-rich region located in a subduction zone that shows a nontrivial behavior: the subduction arc changes the seismic activity from the eastern zone to the western zone, showing a decrease in this activity along the subduction. We analyze this zone through the Tsallis entropy and the mutability (or dynamic entropy). The data set used for this analysis was measured between 2000 and 2023, considering 19549 seismic events. We have found an agreement between the results for the two entropies. We have followed the value of the q parameter of the Tsallis entropy, finding values between 1.70 and 1.85, in concordance with values previously found in other seismic regions of the planet. Also, the values of the q-parameter tend to decrease over time but show an increase before the main earthquakes. Mutability also shows a tendency to decrease over time and an increase previous to the main earthquakes. To deeply analyze this zone, we divided the region into four sub-zones. The results show how mutability can identify the seismic activity in each zone. This study shows how an entropy approach can shed light on understanding the seismicity in subduction zones.

Kerusakan irigasi secara visual terdapat tanda-tanda korosi pada tulangan beton, seperti karat dan lapisan korosi. Dalam bidang pembangunan irigasi, teknologi ferosemen menjadi hal yang penting. Komposisi utamanya, yang terdiri dari semen, pasir, air, dan tulangan, dapat ditingkatkan dengan bahan alternatif tambahan seperti silica fume untuk meningkatkan ketahanan terhadap korosi. Penelitian ini bertujuan untuk mengetahui pengaruh silica fume dengan berbagai persentase (0%, 6%, dan 9% dari berat semen) terhadap karakteristik mortar dalam penerapan beton pracetak ferosemen. Pengujian dilakukan melalui pengukuran kuat tekan pada berbagai umur (3, 7, 14, 21, dan 28 hari), serta pengujian resapan air dan rembesan air pada umur 28 hari setelah perawatan. Hasil penelitian menunjukkan bahwa penggunaan silica fume mengakibatkan penurunan kuat tekan pada benda uji kontrol sebesar 20,96 MPa. Hal ini disebabkan oleh reaksi antara silica fume dan semen, yang memperlambat proses pengerasan. Selain itu, penambahan silica fume mengurangi resapan air pada mortar, dengan penurunan yang lebih signifikan seiring dengan peningkatan persentase campuran. Pengujian rembesan air pada beton pracetak ferosemen menunjukkan tingkat rembesan yang rendah, dengan nilai sebesar 21% setelah 24 jam, menandakan bahwa campuran ini cocok untuk aplikasi beton pracetak ferosemen. Dengan demikian, penggunaan silica fume dapat meningkatkan kualitas dan ketahanan beton pracetak ferosemen terhadap korosi.
Certain problems with the use of terms in legislation

The author of the article expresses his views on the use of terms in the text of legislation in the state language.It should be noted that in the first years of independence, the language of legislation should be fluent and understandable, and the gross mistake of taking terms differently depending on the context still persists. Emphasizing the relevance of the problem of terminology in jurisprudence, the author focuses on the role of language in the accurate expression of the will of the legislator.He proves by examples in the current legislation that the invention of new terms, considering that it should be understood according to the meaning of the text while applying the legislation, impedes the implementation of the law, that a legal concept becomes a legal term only when it is enshrined in a legislative act and formalized in the appropriate official form.He notes that the different use of terms used in the law in the press confuses the public. The author refers to the article by Gulzhazira Aktorekyzy Ilyasova published in issue No.1 (46) of the Bulletin of the Institute of Legislation of the Republic of Kazakhstan in 2017, to prove that opinion as one word-one concept in normative acts is an invariable principle, that the use of polysemantic words, synonyms in one law and laws that are similar to each other leads to non-implementation of the law.Expressing his agreement with the author's opinion, he emphasizes that the structure of the sentence should not contradict the need for a deep and final nature of the regulated object, should not infringe the legal meaning, accuracy, clarity and completeness of the text of the legislation.

Modern data mining employs the use of statistics with other tools, ideas and approaches from computer science, database technology, machine learning, deep learning as well as other classical analytical tools. In this research, three distinct algorithms have been employed for modelling the performance properties of Diazepam (DIA) utilizing the method of high-performance liquid chromatography (HPLC). The algorithms developed include support vector machine (SVM), adaptive-neuro fuzzy inference systems (ANFIS), and linear regression (LR). Temperature and mobile phase inform of methanol (MeOH) were used as predictors, while the time recorded for the retention was deemed to be the dependent variable. The performance accuracy of the models was assessed using two statistical metrics, including determination co-efficient (R2) and root mean square error (RMSE). The obtained results were shown both qualitatively and graphically using different charts. The comparative performance accuracy of the models demonstrates that the non-linear models (ANFIS and SVM) displays a higher performance efficiency than LR and has the ability of enhancing its performance ability by 51.2% and 76.1% both throughout the training and testing phase.

The research investigated the dynamics affecting the implementation of target costing in startups in Thailand. Startups face turbulent and competitive environments, lack of market demand and regulatory hurdles, which require effective cost management strategies. The study used quantitative methodology to evaluate the effect of various factors - perceived environmental uncertainty, competitor influence, product diversity, firm revenue, and business strategy for the adoption of target costing. Primary data from a sample of 314 respondents were used. The constructs validity and reliability were analyzed using Confirmatory Factor Analysis while Multiple regression analysis was used to evaluate the study hypotheses. The findings indicated that adoption of target costing was positively and significantly influenced by perceived environmental uncertainty, competitor influence, firm revenue, and business strategy, while product diversity has an insignificant influence. The study recommended that startup managers should consider using complex cost management techniques, as a means of acquiring competitive market advantage, strategic alignment of cost management and using competitors as a benchmark to evaluate their market competitiveness.
Statistical Implementation for SD-RNN Model for Multi-Class Classification for Network Intrusion Detection System
Authors: Nekita Chavhan
Published: June 2024

With the increasing popularity of technologies that depend on computer networks, providing security is of paramount importance. Consequently, intrusion detection systems (IDS) play a vital role in monitoring these networks. An essential element in securing the network of an organization is the Intrusion Detection System (IDS), which serves as the primary barrier against cyber threats and is tasked with thwarting illegal entry into the network. Flow-based network traffic analysis is commonly used in IDS solutions to identify security concerns. In recent years, several innovative strategies have been proposed and implemented to address the issue of network security, with a specific focus on Intrusion Detection Systems (IDSs). The creation of intrusion detection systems using AI methods is a modern method for finding breaches in a network. Since there are many possible approaches, it is important to have a standardized method that facilitates good judgement when classifying intrusions. This paper presents a novel approach utilizing deep learning and machine learning modelling to develop a model for multi-class classification. The principal objective is to create IDS that can effectively detect anomalies using flow-based analysis. The latest CICIDS2017 dataset is used in experimentation for testing and training. The experiments performed with a deep learning model for IDS produced promising results, achieving a 99.77% accuracy rate for multi-class classification while employing the specific dataset.

A widespread prevalence of barotrauma among ventilated COVID-19 positive patients was observed during the pandemic. Some studies have associated COVID-19 related barotrauma with a longer length of hospitalization, longer ICU stay, and higher mortality. Pneumorrhachis is the presence of intra-spinal air, it is a rare finding and is associated with different etiologies and possible pathways of air entry into the spinal canal. Air within the spinal canal can be separated into primary and secondary pneumorrhachis, and then further classified into extra- or intradural pneumorrhachis. We present a case of severe COVID-19 infection requiring mechanical ventilation, proning, and subsequent barotrauma in the form of pneumomediastinum, and pneumorrhachis, that resolved with careful watching. This case demonstrates the ongoing challenges of mechanical ventilation and barotrauma in COVID-19 patients. Although uncommonly associated with viral pneumonia, a higher incidence of barotrauma is being observed with COVID-19 infection. Given how rare and the different causative factors are, no standardized guidelines exist for the treatment of pneumorrhachis. It is however, thought to be associated with an increased morbidity and mortality. In this case, the air appeared to be contained by the dural sac and there was no resulting pneumocephalus. Although in general, this phenomenon is usually self-limiting and without further consequences, prompt consideration of the underlying cause is of extreme importance.
