Background: The corona virus, a novel, enveloped single stranded RNA virus (sarscOv-2) which has mainly affected respiratory system with life threatening results. The SARS-CoV-2 has been detected in several body fluids including tear and discharge of patients suffering from conjunctivitis. The aim of this paper is to explore the nursing care of person with ophthalmic problems.

Methods: A literature review was conducted using data based of Google scholar, Google, Pubmed, Medline since 2015-2023.

Results: An ophthalmic nurse can play a key role in teaching a patient and their attendants about general eye care and protection of vision during COVID-19 monitoring the patient’s condition, as well as ophthalmic instruments after it’s use have been are two main responsibilities of the nurse working in the ophthalmic units. Nurses also have responsibilities to maintain the safe and clean working environment of the unit, making the environment clean and safe.

Conclusion: The environment of the eye ward must be clean, safe and free from organism. A nurse should warn the patients not to touch or rub the eyes and dressings or eye shields with unprotected hand during this COVID-19 pandemic.
A Review of the Impact of Nigerian Tourism Development in the Preservation of Arts and Culture
Authors: Adekunle Quawih
Published: April 2024

This study investigates the responsibilities that museums play in conserving art and culture. It argues that museums should be responsible for making historic values accessible and understandable to all visitors, rather than depending simply on traditional item displays. Museums provide opportunities for global travelers to learn about different perspectives on the importance of history and how to preserve their heritage. The method used in this research is qualitative. Research was carried out by compiling and analyzing existing studies. The obstacles to the preservation of art and culture, and how can research help museums use their physical, intentional forms to produce visitor experiences that are meaningful, active, ethical, and continuous, as well as a visible representation of tourism in Nigeria served as the focal points of this paper’s research.  The findings support the dual functions of museums, preserving our artistic heritage and acting as a significant source of revenue to support the travel and tourist industry. In addition to significantly increasing global income, tourism is now a key factor in the expansion of economies across the world.  The primary rationale behind the growth of tourism in many nations worldwide is often its capacity to have a favorable economic impact through the lens of modern heritage values and ethics. The findings of this research reflect the intricate ways by which tourism and culture are tightly correlated.

Published: April 2024

Objective : In Madurai, early childhood caries and pregnancy gingivitis are still common. The purpose of this study was to evaluate the knowledge and attitudes of expectant mothers on pregnancy gingivitis and the dental health of their unborn children. Study design: An awareness survey was conducted in a clinic offering prenatal care. Pregnant women were given a written dental hygiene questionnaire about early childhood caries and pregnancy gingivitis. Of the fifty expectant mothers who signed up for the research. Results: Just 33% of the 50 participants correctly identified the connection between pregnant gum disease and hormone changes. Just 34% of patients had gingivitis, which was indicated by swelling and redness of the gums. Furthermore, a majority of the pregnant mothers surveyed, 58% of them, were unaware of the recommended toothpaste dosage for a child between the ages of eighteen months and 5 years. Nearly 25% of respondents said that a replanted avulsed tooth wouldn't likely survive the brief extra-alveolar time of less than 60 minutes.. Conclusion: Most expectant mothers are ignorant of what constitutes appropriate oral health care for their unborn child and about a common mouth condition that develops during pregnancy. A before birth care program should include teaching in oral medical services.
A Comparative study on Short term load forecasting using BPNN and Extreme Learning Machine.
Authors: Pati J C
Published: April 2024

Short term load forecasting plays a very important role in planning and operation of electrical utilities. Accurate forecast of electrical load is highly essential for Energy Management System. Neural network uses artificial intelligence by adjusting weights and minimizing the error. The learning speed of feed forward neural network is very slow mainly due to two reasons :- i) slow gradient-based learning algorithms to train neural networks, ii) all the parameters of the networks are tuned iteratively by using such learning algorithms. This paper presents a comparative study of back propagation algorithm and an extremely fast learning technique. A final optimise set of weight are used for prediction of actual load with greater accuracy and less time using ELM.
Implementation of Cryptography Core
Authors: Santhosh Kumar M
Published: April 2024

The continuous increase in demand for security in electronic systems and communication systems which lacks a secure architecture has resulted in the need to provide cryptography architecture with high secure core. The hardware implementation of the cryptography core which incorporates multiple algorithm for security purpose was already developed but if the architecture is capable of switching between the algorithms used for encryption /decryption as controlled by the host computer dynamically, then the security over the data path will be increased by making the attempt for hacking too difficult. The switching between heterogeneous algorithms will also increase the confusion level. This proposed architecture implements three symmetric algorithms namely the standard AES, standard DES and proposed modified DES (MMDV) algorithms. Representing these algorithms in the functional block level and also using the new concept of common S-Box , results in operations that are common to all the three algorithms, allows us to merge them in a single architecture and thus there is an area reduction of 14.5% in cryptography core with 2 S-Boxes rather than using 11 S-Box. The operation of this cryptography core is controlled by the control signals, selecting which algorithm to work at time, making it difficult to hack the information transferred through the data line
Rough Set Approach to Development of a Knowledge-Based Expert System
Authors: Panda B S
Published: April 2024

In this paper we propose to model of a knowledge-based expert systems using the techniques of Rough Sets approach. In the real world problem solving is the process of finding a solution when the path leading to that solution is uncertain. The Expert Systems need to have the ability to handle vague associations, for example by accepting the degree of correlations as numerical certainty factors. When the data is incomplete or missing, the only solution is to accept the value “unknown” and proceed to an approximate reasoning with this missing value. Rough sets provides a framework to model uncertainity, the human way of thinking, reasoning and the perception process. To run an expert system, the engine reasons about the knowledge base like a human. In the 80's a third part appeared: a dialog interface to communicate with users. This ability to conduct a conversation with users was later called "conversational". Rough set theory is a technique deals with uncertainty.

Physico-Chemical analysis of drinking water samples of Pentapadu village
Authors: Madhava Sarma D
Published: April 2024

Water contains impurities depending upon its source of water. The physical and chemical impurities impart odour, colour and turbidity. Taste and odour may also be caused by dissolved organic matter or by microorganisms such as algae. Colour is generally due to the presence of colloidally dispersed organic matter or because of compounds like iron oxide. Odour is caused by the suspended or colloidal matter. Bacteriological impurities are caused by pathogenic bacteria such as E coli and typhoid bacillus. In the present work ground water samples are collected from various places in Pentapadu village. Pentapadu village is located between 16o45’-17o30’Northeren Latitude and 80o55’-81o55’Eastern Longitudes of West Godavari District of Andhra Pradesh. Water analysis was carried out and physico chemical properties are studied. It was observed that most of the parameters are differing from place to place and no uniformity was observed. Most of the people in Pentapadu village were using bore water and well water for drinking purposes. These waters are found to be hard waters and found to contain dissolved salts along with bacterial impurities.

In this research, some groundwater specifications were evaluated for 5 areas of well water located in different areas in Zawiya city. These areas included (Warshfana, Al-Zawiya Al-Markaz, Dilah, Sayyida Zeinab, South Al-Zawiya), where some of the physical and chemical properties of well water samples were studied and the results were compared with the Libyan standard of 2015 and the specifications of the World Health Organization (WHO). This study showed that the well water samples that were studied are not suitable for human drink because they do not conform to international standards for drinking water, except for the water samples that were collected from the Warshafana area, where it was found that the concentration of total dissolved salts in the water samples collected from the Al-Zawiya Al-Markaz area, Sayyida Zeinab area and the Dilah area fall within a range greater than (1000 ppm). As for the samples from the Dilah region, the salinity level was very high as it is an area close to the sea, and therefore the water needs treatment and desalination operations before it can be used.

NOVEL SYNTHETIC INVESTIGATION IN THE FIELD OF INDOLO[2,3-B]QUINOXALINE RING CONTAINING TETRACYCLIC AND PENTACYCLIC HETEROCYCLES
Authors:   Department of Chemistry, Faculty of Exact and Natural Sciences, Ivane Javakhishvili Tbilisi State University, Georgia, Bobokhidze Lia
Published: April 2024

A series of seven new indolo[2,3-b]quinoxaline ring containing compounds were efficiently synthesized in three different pathways. In the first case, the relevant pentacyclic systems (3,4) were received by the condensation reaction between 7-acetyl-1,5,6,7-tetrahydropyrrolo[3,2-f]indole-2,3-dione and o-phenylenediamine in glacial acetic acid. In the second case, tetracyclic indolo[2,3-b]qui-no¬xa¬li¬ne derivatives (7, 8a-d) were synthesised by a one-pot approach using Pd-catalyzed Sonogashira-hagihara C-C cross-coupling reaction between various terminal acetylenes and 9-iodo-6H-indo¬lo¬[2,3-b]quinoxaline in presence of various Pd catalysts. The third pathway is based on the Cu-catalyzed modified Ullmann protocol. The appropriate indolo-quinoxaline derivative (9) was successfully syn¬the¬sized by arylamination, using benzylamine (as a nucleophile) and 6-benzyl-9-iodo-6H-indolo[2,3-b]qui¬no¬xaline as an aryl halide. The reaction was performed in DMF in the presence of CuI.

Authors:   Department of Electronics and Automation, Azerbaijan State Oil and Industry University, Baku, Azerbaijan, Hashimov Kh.Kh.
Published: April 2024

The article is devoted to the physico-chemical and structural phenomena that occur under the influence of the partial replacement of Cu atoms with Ni atoms in Cu2S crystals on the mechanism and nature of the phase transition. For this purpose, X-ray phase analysis of single crystals Cu_(2-x) Ni_0.05 S (x=0.05,0,25,0,30) was performed, which were synthesized and grown in the laboratory for the first time. A diffractogram of the crystal Cu_1.70 Ni_0.05 C, Cu_1.75 Ni_0.05 C, Cu_1.95 Ni_0.05 C was prepared at a room temperature. The results were analyzed. Thus, it was found that, unlike non-stoichiometric Cu_(2-x)S compounds having two and three phases at room temperature, the obtained crystals Cu_1.70 Ni_0.05s, Cu_1.75 Ni_0.05s and Cu_1.95 Ni_0.05s are single-phase. The reliability of the experimental results were confirmed by the theoretical calculations using the example of the fragment taken from the diffractogram of the Cu1.95Ni0.05S crystal (radiation: CuKa (λα=1.5418 A0), filter-Ni, mode: 35 kV, 10 mA).

Opportunities for Citizens to Participate in Organising Elections in Europe
Authors:   Aarhus University, Albertsen Andreas , Lever Annabelle ,   Sciences Po Paris
Published: April 2024

Part of the aim of the REDEM project is to identify and develop new ways of engaging citizens in elections, whether they are currently willing or entitled to vote. This chapter discusses one particular idea for expanding citizens' electoral participation: To employ those currently disengaged with electoral democracy as electoral support staff (i.e., polling station staff) on election day. It focuses primarily on those who are too young to vote, and on adults who are not allowed or are not willing to vote. We examine the experiences and theoretical merits of a proposal that seeks to engage citizens with democratic elections by opening opportunities to take part in their administrative aspects, even if they are unwilling or ineligible to vote. The chapter first identifies a gap in the existing approach to engaging voters in a democracy and situates the current proposal as a halfway-house between approaches that engage citizens as voters and those that engage them through non-electoral measures. Engaging citizens as electoral support staff is different from engaging them as voters. To enhance our understanding of what the proposal entails the chapter provides a comprehensive overview of the tasks currently performed by electoral support staff. It then examines the barriers to introducing the proposal by looking at current limits to who is allowed to fill the roles of polling station staff across a wide range of European countries. Doing so provides a picture of current limits and opportunities for engaging the politically uninterested or disengaged in electoral democracies.
La Relación De La Fenomenología Y La Psicología Como Un Motor De La Fenomenología Trascendental.
Authors: Martín Javier San
Published: April 2024

Mi objetivo es explorar el núcleo aporético de la relación de la fenomenología con la psicología, que pasará por tres etapas, una primera en la que la fenomenología es un tipo de psicología; una segunda, en la que Husserl distingue perfectamente la fenomenología de la psicología; y una tercera, que podríamos calificar como un tránsito de la claridad de la separación, de la segunda etapa, a la imbricación. El ensayo tendrá, entonces, tres partes; primero, delinearé la exposición de Husserl de su fenomenología como una psicología descriptiva en la primera edición de las Investigaciones lógicas; la segunda, en la que, una vez superada la primera etapa en que la fenomenología se veía como psicología, se expondrá cómo Husserl, sobre todo en Ideas I, formula una fenomenología neutral apta para la psicología y la fenomenología trascendental. En esta parte mostraré el cambio que sucede a mitades de la década de los años veinte, con la aparición de la teoría de los tres yoes, fundamental para resolver las polémicas sobre la reducción y la epojé. En la tercera parte mostraré la necesidad de problematizar esa posición desde lo que se dice al final de la conferencia sobre “Fenomenología y Antropología”, y en el § 72 de La crisis.
A Ontologia de Sartre: Dualismo e "Ser Todo”
Authors: Sass Simeão Donizeti , Gallian Dante Marcello Claramonte
Published: April 2024

A intenção deste estudo é demonstrar como Sartre formula e soluciona a questão do dualismo na obra O Ser e o Nada. Tal questão surgiu sobretudo a partir das críticas de Alphonse de Waelhens e Maurice Merleau-Ponty. Essas críticas foram sintetizadas no prefácio da obra de Merleau-Ponty intitulada La Structure du Comportement. Essa temática se torna muito importante porque o suposto dualismo tornou-se uma ideia comum, um erro que foi persistentemente considerado como verdade. Para corrigir esse erro e recobrar a real face da filosofia sartriana, é importante ouvir a voz de Sartre. É indispensável o retorno ao que ele escreveu na Conclusão de O Ser e o Nada, para reaprender as bases de sua ontologia e para restaurar a verdade dos fatos.

Published: April 2024

Com o objetivo de esclarecer as principais determinações do nosso horizonte histórico e como elas aparecem nos modos de ser e estar do homem contemporâneo, realizamos pesquisa bibliográfica em uma Revisão Narrativa da Literatura. Guiados pela fenomenologia-hermenêutica de Heidegger, principalmente no seu texto A questão da técnica, seguimos nosso caminho na tentativa de uma apreensão mais originária dos sentidos que fundamentam nosso horizonte compreensivo. Considerando as reflexões de Bauman, em Modernidade líquida, e as análises de Duarte em Vidas em risco, propomo-nos a realizar uma caracterização da época contemporânea e descortinar outras possibilidades de compreensão da mesma, levando em consideração os modos de ser e estar do homem na cotidianidade mediana desta Era da técnica. Assim, pretendemos elencar elementos que tornem possível uma investigação psicológica inclinar-se sobre as questões sociais a partir das articulações historicamente constituídas na relação homem-mundo, superando as dicotomias vigentes entre uma interioridade psíquica e exterioridade social.
EL TERCERO INDISCRETO. PROYECTO DE FENOMENOLOGÍA GENÉTICA
Authors: Richir Marc , Suárez-Astaiza Jeison Andrés
Published: April 2024

¿Es posible hablar de una intimidad irreductible a una interioridad psicológica? El siguiente texto explora una respuesta a partir de las relaciones intimas y muy precoces del bebé con la madre, constituidas en la intimidad y que constituye a su vez la figura del tercero indis-creto. Esta relación de sí a sí fundada (fundiert) sobre la relación primitiva y primordial del sí--mismo al sí-mismo maternal es la relación que define la intimidad, y no tiene nada de espacial, ni siquiera de ek-stática, aunque suponga necesariamente, con el juego sin reglas (Winnicott), la mediación del objeto transicional. Esta intimidad la experimentamos todos ciertamente en grados muy diversos. Porque, precisamente, existe el tercero cuya función primitiva es la de la indiscreción. Es desde el concepto de “espacio transicional” que se tematiza lo no-posicional en fenomenología, aquello que se pone en juego antes de la institución simbólica y tiene lugar en un nivel transcendental sito no tanto en el registro de lo intersubjetivo sino en el de una interfacticidad transcendental dual y originaria.
La propension à s’engager dans l’entrepreneuriat chez les étudiants de l’IUT/UP : une analyse par la théorie de l’évènement entrepreneurial de Shapero et Sokol.
Authors:   CRECI/IUT – Université de Parakou, AIFA Emile
Published: April 2024

Résumé : Dans les universités béninoises, l’enseignement de l’entrepreneuriat semble être assimilé, de nos jours, à un précieux outil de création d’emplois et un levier important pour faire face au récurrent problème de chômage. Cependant, force est de constater malgré ce dispositif intéressant que nombre d’étudiants, après leur cursus universitaire, ont du mal à se lancer dans les affaires. Le but visé par cet article est de chercher à comprendre si la variable « attrait » fonde un tel comportement de la part des étudiants de l’Institut Universitaire de Technologie de l’Université de Parakou. A cet effet, cette étude s’est appuyée sur la théorie de l’évènement entrepreneurial de Shapero et Sokol (1982) pour estimer une régression logistique binaire. L’objectif visé est d’expliquer l’intention entrepreneuriale de ces étudiants. Les résultats obtenus montrent que si ces étudiants sont encouragés par leur entourage et ont l’aptitude ou la capacité requise pour aller à l’entrepreneuriat, un faible attrait caractérise leur comportement. Une révision du programme de formation en entrepreneuriat par l’introduction de modules professionnels cohérents fondés sur une logique d’incitation à l’entrepreneuriat est alors nécessaire. Mots-clés : Attrait – Intention – Entrepreneuriat – Etudiant – Formation. The propensity to engage in entrepreneurship among IUT/UP students: an analysis using Shapero and Sokol's entrepreneurial event theory. Summary: In Benin's universities, teaching entrepreneurship seems to be seen these days as a valuable job-creation tool and an important lever for tackling the recurring problem of unemployment. However, despite this interesting system, many students find it difficult to start their own business after graduating from university. The aim of this article is to understand whether the "attractiveness" variable underlies such behavior on the part of students at the University Institute of Technology of the University of Parakou. To this end, this study used Shapero and Sokol's (1982) theory of the entrepreneurial event to estimate a binary logistic regression. The aim was to explain the entrepreneurial intention of these students. The results obtained show that, while these students are encouraged by their entourage and have the aptitude or ability required to go into entrepreneurship, a weak attraction characterizes their behavior. It is therefore necessary to revise the entrepreneurship training program by introducing coherent professional modules based on an entrepreneurial incentive logic. Keywords: Attraction – Intention Entrepreneurship – Student – Training JEL Classification : A29 – L26 – I29 – M19.

Authors: Han Shuai , Yin Shi , Liu Lirui
Published: April 2024

This article explores in-depth entrepreneurship, focusing on business models and business plans. Taking the difficulties and challenges faced by college students as an example, it analyzes the importance of business model innovation to entrepreneurial enterprises and its key role in market competition. The article first summarizes the concept of entrepreneurship and the problems it faces, and then introduces the business model and its application in entrepreneurship, the definition and components of the business plan, and how to make an effective business plan according to market demand, technology trends, and the competitive environment. This paper points out that a successful business model needs to be closely combined with market positioning, product strategy, marketing means, profit model, and other elements, and the formulation of a business plan requires rigorous steps. The study has concluded that the business model is the core of the business plan, and the plan is the specific implementation of the model. The two need to adjust to each other and jointly determine the success of the enterprise. The future development trend of the business model and business plan is the trend of digitalization and intelligence, personalization and customization, flexibility, and adaptability. This paper puts forward suggestions for entrepreneurs represented by college students: an in-depth understanding of market and customer needs, the need to maintain innovative thinking, the feasibility of a socialist plan, etc., thus improving the success rate of entrepreneurship. This paper enriches the relevant theories of entrepreneurship, lays the foundation for in-depth research, and has certain theoretical significance.

ThreshNet: a Novel Machine Learning Technique to Optimize Sensitivity and Specificity Performance
Authors: Xu Shirley
Published: April 2024

In image classification applications for medical diagnosis, sensitivity and specificity are important performance metrics that are often inversely related. Both high sensitivity and high specificity are not always achievable for a given neural network; the trade-off and balance between them are not easily controllable. This paper proposes "ThreshNet", a novel method to address this dilemma. ThreshNet is composed of an ensemble of different neural networks. Many well-known networks were leveraged through transfer learning. With custom-designed dense layers, network parameters were tuned to optimize performance and enhance the diversity of members in the ThreshNet networks ensemble. To yield the ThreshNet system's decision, a threshold-based algorithm is proposed. Demonstrated with a brain tumor MRI dataset, ThreshNet systems consistently outperform individual networks. Specific sensitivity-specificity trade-offs and optimization goals can conveniently be achieved by adjusting the threshold parameter. Performance variance among ThreshNet systems is smaller than those among individual networks. To locate tumor(s) predicted by ThreshNet, a ResUNet-based image segmentation model was developed, achieving a Tversky index of 90.49% in predicting pixel-wise masks to mark tumor locations.

Authors: Juang Jengnan , Radharamanan R. , Lowe Spencer , Nguyen Thong , Williams Trenton
Published: April 2024

A portable, light weight, low-cost, dual-axis solar turtle prototype with dynamic self-tracking solar panel was designed and fabricated using 3D printed, machined, and purchased components to charge a battery large enough to run multiple devices. The base and body of the design housing is a locking lid rolling cooler that insures if the unit is tipped over the components inside will not be damaged. The design also makes the unit slightly weather resistant. Utilizing a fixed main post made from lightweight strong material allows for the main panel to have a height of 5 feet off the ground or 1 foot off the base of the design for the solar cell to operate. PVC was chosen due to its hollow center and strong and slightly flexible body that is lightweight. All parts needed for the prototype design were purchased along with some parts being 3D printed. Some aluminum milled pieces were used in the final design due to the large amount of load needed to handle at certain points of the build. Implementing a practical "yes/no" function will verify proper angle and exposure of the panel towards the sun, using miniature solar panels that will be eclipsed by the larger solar cell whenever directly facing the sun itself. The dual-axis solar turtle built is marketable and more efficient than static panels due to auto-tracking. When tested, it collected 19.9% more solar energy than static panels.

This study is intended to develop a life cycle impact assessment method, named as Life Cycle Risk Assessment (LCRA), that can evaluate the potential risk from hazardous chemicals exposed to human and ecosystem throughout product's life cycle. For this, this study considered three risk categories such as human cancer, human non-cancer and eco-toxicity. In addition, it developed the technical procedures that can calculate not only the potential risks of three categories but also total potential risk integrating each quantified risks. For calculating the potential risks under domestic environmental condition, this study developed exposure indices by applying both 146 Toxic Release Inventories (TRI) published from the ministry of environment and the data associated with domestic atmosphere volume, domestic waterborne volume, average span of life and duration time. Also a case study of laundry detergent is presented below as an example to explain the application of the LCRA method.

Published: April 2024

This study discusses how to stimulate the development of the eco-efficiency assessments in the Korean electronics industry. It surveyed best practices related to the eco-efficiency assessment and communication around the world. The applicability and usefulness of eco-efficiency assessments was tested through discussions with the Korean electronics industry. The semi-structured interviews with corporate managers revealed that an eco-efficiency has an appeal for the companies as a philosophical concept denoted as “doing more with less", while a lot of effort need to be made to get companies to actually initiate eco-efficiency assessments. There is an urgent need to increase the simplicity in the eco-efficiency assessment framework and to clarify its implications to the business operation.In addition, the role of the government related to capacity building is very important.

Published: April 2024

Eco products are developed to reduce environmental impacts throughout all life cycle phases from material acquisition to disposal. The present study proposed novel design solutions of electric hair dryer by considering performance and usability as well as eco-friendliness. Preferred design features were identified by benchmarking two electric hair dryers (companies ‘J’ and ‘V’) using performance measurements (temperature, air speed, noise, and electric power consumption), usability scores (informativeness, ease of learning, ease of button operation, grip fit, and overall satisfaction), and eco-friendliness indexes (global warming potential and recyclability rate). Design solutions (e.g., brushless DC motor, Teflon case, honey comb coil structure, memory button, removable dust filter, and recycling promotion) of electric hair dryer were proposed for better energy efficiency, user friendliness, and recyclability. These proposed concepts would be useful as a design guideline for an eco-friendly electric hair dryer.
