Authors: Islam Md Rafiqul , Muhammad Mahbubur Rahman  , Mohammed Ataur Rahman  , Muslin Har Sani Mohamad  , Abd Halim Embang
Published: April 2022

The alternative energy generation sources have increased drastically from centralized systems to distributed systems which increases the stability of energy distribution management systems and reduces the distribution cost as well. On the other hand, it reduces the probability of major area electricity blackout chances and decreases the energy distribution loss. For proper distribution and management of energy, there are different types of advanced technologies like artificial intelligence, and the Internet of Things (IoT) available, but a blockchain automated system is one of the best choices and is highly recommended. Various aspects of blockchain technology and energy management system have been discussed in this review paper where a total number of 423 journal papers, articles, and online information sources have been reviewed in the initial stage, and finally, 63 published research articles have been selected for review. There are several topics, including technology overview in energy management systems, blockchain application of energy trading, blockchain technology implementation challenges, distributed energy management system with Ethereum, and a conclusion with some recommendations have been discussed. Blockchain and Distributed Ledger Technology (DLT) are highly transparent, authenticate, and secure systems that can be used for distributing the energy between distributor and consumer without an intermediator which increases the overall efficiency of the system. This paper aims to highlight the blockchain and distributed ledger technology and how it works as well as optimize the transaction processing cost among the participants of the consortium network. This paper will make a significant contribution to the new research work and in the field of energy management systems.
Pedagogical Practices for Organizing Simulation-Based Healthcare Education
Authors: Keskitalo Tuulikki
Published: April 2022

Despite the positive findings on the results of simulation-based health-care education, what truly makes it successful remains unclear. We do not know enough about when and how the simulation-based learning environment (SBLE) should be applied. Thus, the specific aim of this thematic-review study was to determine what the facilitators’ peda-gogical activities are in the simulation-based education process. For this purpose, the study reviewed 83 previous studies in which the ped-agogical practices were explained or examined. Based on the literature review, the pedagogical practices have been clearly linked to facilita-tors’ activities before, during, or after simulation. Most of the research has focused on facilitators’ activities during simulation-based educa-tion, especially during the debriefing phase. Some studies have exam-ined pre-simulation activities, but the research concentrating on facili-tators’ post-simulation activities is limited. All in all, this thematic lit-erature review provided insights on the successful pedagogical prac-tices for implementing the simulation-based health-care education process. To further develop simulation-based health-care education and to optimize the use of such a learning environment, scholars should describe facilitators’ and learners’ activities more accurately; and they should use more rigorous research methods to analyze the teaching and the learning activities. Furthermore, such knowledge should be synthesized and used to develop pedagogical models and methods for simulation-based healthcare education and to integrate them into various learning contexts.

Authors: Mpisi Anthony , Alexander Gregory
Published: April 2022

The purpose of this paper is to report on a research study which explored the perceptions of black learners with regard to their teacher-learner and learner-learner relationships in multicultural spaces of Historically White Schools in the five educational districts of the Northern Cape province in South Africa. A quantitative research approach, embedded in a descriptive data method of data analysis was employed, where a self-designed 4-point Likert scale questionnaire was given to 1037 black high school learners attending Historically White Schools in the Northern Cape. Learners used for the study included learners in grades 10 to 12. Selected items related to black learners’ perceptions of their relationships with their teachers and fellow learners in Historically White Schools. Data were analysed using descriptive analyses. In general, the study revealed that black learners experienced relatively pleasing relationships with their teachers and fellow learners alike. The study is noteworthy, as it reveals that black learners attending Historically White Schools feel accepted and respected by their teachers and fellow learners, which, in turn, is favourable for learners’ emotional security, sense of belonging and academic achievement. The study further highlights the critical value of teacher-learner and learner-learner relationships to learning, interaction, socialisation and communication in Historically White Schools, noting the tendency of these schools to assimilate black learners into the existing school culture, which is fundamentally based on Eurocentric values.

Published: April 2022

Development of tailor-made indigenous teaching content, after assessing the target learners’ needs and proficiency, is necessary to address to specific needs of specific learners, ensure optimum learning and motivation. This quantitative investigation attempted to determine the communicative competence of SSETH in English language skills to develop indigenous teaching content. A Likert-scale questionnaire was developed and administered to 289 participants to record their perceived proficiency in English language skills and sub-skills. Independent-samples T-test was run to generate descriptive statistics and determine whether any significant differences exited in their perceived proficiency level. The results revealed medium low English language proficiency by the participants. SSETH reported comparatively higher proficiency in the productive skills of writing and speaking as compared to the receptive skills of listening and writing. The cohort form College of Tourism and Hospitality, Taif (CTHT) reported slightly higher competence as compared to their counterparts from College of Tourism and Hospitality, Madinah (CTHM). Comparative results generated by Independent-samples T-test rejected the null hypotheses as no statistically significant differences were found in the perceived communicative competence of both groups. It is recommended that various stake holders should work in close coordination to develop and implement indigenous teaching content which should be periodically assessed and modified to suit the changing ESP needs of SSETH. This procedure may be followed as a model for other disciplines to develop indigenous teaching material.

Authors: Jonáková Stanislava , Šikolová Mária , Veselá Magdalena
Published: April 2022

This paper aims to identify and compare aspects affecting English language syllabus design at military language centres in six NATO countries. Close attention is devoted to course syllabi for Level 1 (Survival; approximately corresponding to the Common European Framework of Reference for Languages (CEFR) Level A2) and Level 2 (Functional; approximately corresponding to CEFR Level B1). The descriptive quantitative research, conducted in 2019, concentrated on determining which stakeholders participated in creating the English language syllabi presently in use and which critical aspects of syllabus design the creators considered in the process of their compilation. The findings reveal that active teacher participation is one of the most prominent characteristics of the entire syllabus design process in all of the institutions examined, which results from the specific nature of the courses focused on preparing learners for final English examinations in a military context. Integrated syllabi, which are product-oriented and teacher-led, are another defining characteristic typical for both levels in all institutions. The syllabi in the countries studied are designed similarly, considering such crucial aspects as the learners’ entrance level, previous syllabus, exit requirements, and the type and length of courses. The study offers new insight into the organisational structure of courses at the elementary level, and an increase in the number of lessons in courses for Level 1 organised within the Czech army is strongly proposed.
Regulation on Intra-group Transactions of Financial Affiliates in Non-financial Groups: The Current Status and Issues
Authors: Shim Haerin
Published: April 2022

This study reviews the current status of the regulation of intra-group transactions of financial affiliates in non-financial groups and analyzes the limitations and loopholes in the regulatory environment surrounding these transactions. Intra-group transactions of group-affiliated financial firms are regulated under (1) the Monopoly Regulation and Fair Trade Act, (2) the Commercial Act, (3) tax laws, and (4) financial statutes and regulations. Despite the existence of various regulations, in practice, regulatory blind spots and loopholes for intra-group transactions undertaken by financial affiliates in non-financial groups remain because of the weakness of the supervisory framework and the nature of financial service transactions. This study contributes to the extant discussion on the regulation of intra-group transactions by focusing on the regulation of intra-group transactions undertaken by financial affiliates that have not received much attention. In addition, this study provides timely policy implications when the new Act on comprehensive group-wide supervision of financial affiliates becomes effective.
Discount Rates, Subscription Prices, and Subscription Rates in Equity Rights Offerings
Authors: Jang Seung-Hyun , Yoon Pyung Sig
Published: April 2022

This study analyzes the wealth effect of discount rates, subscription price announcement effects, and subscription rates with 407 equity rights offerings (with unsubscribed shares to the public) announced between 2004 and 2016. The major results of this study are as follows. First, the market not only responds negatively to the right offering announcements (3-day CAR of -13.83%) but also to announcements of final subscription prices (3-day CAR of -4.85%). The announcement effects of final subscription prices are not related to changes in subscription prices, but become more negative as announcements are delayed. Second, the discount rate significantly affects the wealth effects. This means that discount rates provide the information on firms’ future prospects. Firms with low information asymmetry and high ownership by the largest shareholders choose lower discount rates. Third, the non-subscription rate is about 14% and wealth transfer due to non-subscription is 7.08% of the amount raised by the right offerings. As the offering process is delayed, the subscription rates decrease. In addition, the listing of subscription rights have a significant positive impact on subscription rates. However, as market value decrease due to a right offering is similar to the amount raised, firms should consider alternative financing methods.
Do Equity Indices Remember Cash Dividends?
Authors: Ko Kwangsoo
Published: April 2022

Most equity indices we come across are calculated without taking cash dividends into account. Therefore, it does not properly represent the performance of equity market, and has several problems as an underlying asset of equity index derivatives. An equity index that does not take into account cash dividends is called a price index, and a equity index that considers cash dividends is called a return index. When a price index is used as an equity index, an inefficient phenomenon occurs in that the dividend yield has a positive (+) effect on the equity return the next day. Furthermore, the relationship between KOSPI 200 futures and spot returns on ex-dividend day goes away from the cost-of-carry model of futures prices, and the basis between their prices decreases in a few days after ex-dividend date. Considering this empirical evidence and the theoretical flaws of the current equity indices, it is now necessary to change the calculation method of equity indices from the price index to the return index method. This will allow equity indices to represent the performance of equity market without any distortion, and will help determine the correct price of equity index derivatives.

El cosmograma de los primeros memoriales
Authors: Camacho Angeles María Montserrat
Published: April 2022

En el códice de los Primeros Memoriales, encontramos una imagen que ha sido repetida en distintas obras. Se trata de la imagen del Recinto Sagrado de Tenochtitlan, que ha capturado el interés de diversos especialistas. A pesar de la gran atención que ha recibido, casi siempre se usa como ilustración o para reforzar algún detalle menor.

Aunque parece una imagen muy sencilla, el investigador pronto se encuentra con dificultades de envergadura. Aquí, intentaremos a partir de un análisis iconográfico, identificar sus elementos básicos: los personajes que aparecen en la lámina y sus elementos característicos, los recintos y muros arquitectónicos así como el rumbo cardinal al que pertenecen, lo cual nos ayuda a dar una mejor interpretación de cada uno de ellos. Para concluir con una lectura general que nos lleva a interpretar el plano terrestre como un cosmograma. Cabe aclarar que los pueblos mesoamericanos concebian al plano terrestre como una plancha cuadrangular, con cuatro postes en cada uno de los rumbos cardinales y un poste central y en tres espacios a nivel vertical el inframundo, el nivel terrestre y el plano celeste.

Authors: Enciso González Jesús
Published: April 2022

A finales del siglo XX aparecen en México una serie de obras, la nueva novela histórica, cuya narrativa manifiesta otra visión de la realidad pasada.  Su característica es que le da voz a los marginados: personajes femeninos y grupos minoritarios que no tienen precisamente la categoría de héroes en la historia oficial. En particular se analiza la novela de “Malinche” de la escritora mexicana Laura Esquivel. En dicho trabajo, se le da vida a Malinalli, quien en la guerra de conquista será conocida como Malintzin, Malinche y ya después como Doña Marina. La novela reivindica la figura de esta indígena y manifiesta, siguiendo las pautas de la nueva novela histórica, una perspectiva donde se aprecia su vida privada, emocional, sentimental y sexual; asimismo nos presenta una adolescente que  repentinamente se ve imbuida en grandes responsabilidades de negociación política, llenándola de incertidumbres, temores y mucho arrojo para conseguir su libertad individual.
The Rights of Royal Patronage and the Legitimacy of anti-Clericalism after the Independence of Mexico
Authors: Gómez Aiza Adriana
Published: April 2022

The Church-State statutory institutional relationship is particularly significant apropos the debate of cultural tolerance. Here, I review the mechanisms by which this relation circumscribes to an ethno-centric pattern in the reading of Mexican history, and examine the discursive atmosphere the Church and the State institutional struggle to master the symbols of nationhood, and account for the ethnic images ratified by institutional narratives with liberal pragmatic postulates. In particular, I focus on the complex netting of political demarcations between religious and civil institutions, and its distinctive tone they acquired under Hispanic Patronage; all of which set the background upon which the Church’s antagonism to official lay discourses on Mexican identity appears futile.

Authors: M. Nanak Zakaria  , Setiawan Achmad , Ahmad Wilda Y  , Lis Diana Mustafa
Published: April 2022

The random noise signal is widely used as a test signal to identify a physical or biological system. In particular, the Gaussian distributed white noise signal (Gaussian White Noise) is popularly used to simulate environmental noise in telecommunications system testing, input noise in testing ADC (Analog to Digital Converter) devices as well as testing other digital systems. Random noise signal generation can be done using resistors or diodes. The weakness of the noise generator system using physical components is the statistical distribution. An alternative solution is to use a Pseudo-Random System that can be adjusted for distribution and other statistical parameters. In this study, the implementation of the Gaussian distributed pseudo noise generation algorithm based on the Enhanced Box-Muller method is described. Prototype of noise generation system using a minimum system board based on Cortex Microcontroller or MCU-STM32F4. From the test results, it was found that the Enhanced Box-Muller (E Box-Muller) method can be applied to the MCU-STM32F4 efficiently, producing signal noise with Gaussian distribution. The resulting noise signal has an amplitude of ±1Volt, is Gaussian distributed and has a relatively wide frequency spectrum. The noise signal can be used as a jamming device in a certain frequency band using an Analog modulator.

Published: April 2022

The primary intent of the current research is to provide insights regarding the management of spare parts within the supply chain, in conjunction with offering some methods for enhancing forecasting and inventory management. In particular, to use classical forecasting methods, the use of weak and unstable demand is not recommended. Furthermore, statistical performance measures are not involved in this particular context. Furthermore, it is expected that maintenance contracts will be aligned with different levels. In addition to the examination of some literature reviews, some tools will guide us through this process. The article proposes new performance analysis methods that will help integrate inventory management and statistical performance while considering decision maker priorities through the use of different methodologies and parts age segmentation. The study will also identify critical level policies by comparing different types of spenders according to the inventory management model, also with separate and common inventory policies. Each process of the study is combined with a comparative analysis of different forecasting methods and inventory management models based on N.A.C.C. parts supply chain data, allowing us to identify a set of methodologies and parameter recommendations based on parts segmentation and supply chain prioritization.

Published: April 2022

Cigarette Smoking has been shown to induce hypercoagulability and a hyper thrombotic state, possibly by increased platelet aggregation and adhesiveness as a result of its nicotine content. During tissue and vascular injury, Fibrinogen (factor I) is converted enzymatically by thrombin to fibrin and subsequently to a fibrin-based blood clot. This study was aimed to determine the effect of cigarette smoking in plasma fibrinogen and platelet levels in male smoker in Nnewi, Anambra state. Apparently healthy 80 male cigarette smokers and 80 male non cigarette smokers, aged between 18 and 40 years, resident in Nnewi were recruited for this study. Four milliliters of blood were collected from each participants (test and control samples), 2ml in trisodium citrate anticoagulated tubes and 2ml in EDTA for the estimation of plasma fibrinogen levels and platelets count respectively. Fibrinogen was estimated using the method described by Clauss. Platelets were estimated using Mythic 22 Automated Hematological Analyzers. The results showed a significant difference between the mean plasma Fibrinogen level in cigarette smokers and non-cigarette smokers (365.90±66.79 vs 203.02±47.40; p= 0.001). There was no significant difference observed in the mean platelets count of cigarette smokers when compared to the mean values of non-cigarette smokers (242.80±94.70 VS 202.84±76.31; p = 0.564). The study concluded that cigarettes smoking elicits an increase in the plasma fibrinogen level.

Published: April 2022

A sequential water balance was performed using the Thorn Thwaite and Mather method in order to verify the contribution of water storage and damming in the municipality of São Bento do Una in relation to the water crisis. The monthly average climatological precipitation data were grouped into 95 years, characterizing a period of climatological normal, where the software was used in electronic spreadsheets to extract the values ​​of the monthly, annual averages of precipitation for the period from 1920 to 2018. Were estimated by the multiple regression line methods applied to the T-estima software, taking into account the geographic coordinates. Climatic impacts have caused changes in the region's water balance in the last decade. Environmental degradation, the local effect of human action, has by itself accelerated the process of modifying the regional climate, thus directly affecting the conditions of the rainfall regime and the availability of water in the soil. It is extremely necessary to use rainwater harvesting and other storage sources for human, animal and plant survival, thus contributing to the agricultural and poultry sector in the region. Climatic impacts may cause changes in the region's water balance, as heavy and short-lived rains are expected, leading to a drop in poultry and agricultural production.

This study investigates the causes, effects and remedies to defects on highway as it affects quality along Pipeline road in Kamazo, Chikun Local Government Area of Kaduna State. The methods used in data collection are, GIS used in mapping the congested area, use of questionnaire and oral interview. One hundred (100) copies of questionnaires were administered to drivers and passengers using the road, in which Cross-Tabulation and 5-point Likert Scale was used for the analysis. Common defects observed are: Potholes, cracks, silt deposit on roadway, honey combs, depression, grasses on shoulders, scouring, fade markings, road signs, vegetation in hydraulic structures, structural failure of hydraulic structures, loss of materials, failed pavement, etc. Common causes of quality defects on highways are: High volume and frequency of heavy duty trucks; roadway as predominant mode of transportation; Lack of maintenance culture; Poor budget allocation for maintenance. Poor funding; defective Design; Poor construction; Defective constructional materials; Poor supervision; Poor drainage system; Defective implementation of QC/QA protocols; Age of road, etc. Common effects of quality defects on highways are: Defective road quality; Inability to forecast travel time; Fuel consumption; Induces stress on road users; Frequent vehicle breakdown on the roadway; High cost of transportation fare indices for inflation; Loss of time on the roads; Accident; Defective distribution of goods and services; Defective security emergency response, etc. Possible remedies to these defects are: provision of adequate funding to maintenance agencies; collate data from monitoring and evaluation; schedule and plan for maintenance; diversify travel modes; improve on QA/QC required for roadwork; provide coordinated and computerized weigh bridge and regular collection of axle loads data; tax vehicles according to axle load beyond certain boundaries to generate fund required to maintain roads; road markings and furniture to be in place; provision of lightings; quality supervision; use of quality materials to required standard & specifications; adopt build-operate-transfer (road retainer ship).

Psychological impact gives more affects to the patient's desire to make a finger prosthesis. Retention is an important factor in the fabrication of finger prostheses. a fairly simple way is to use the vacuum effect which can be obtained from modifying the stone model of the finger. The present article uses a technique to get retention from passive vacuum fit. This method can be used to fabricate finger prostheses with simple materials and will reduce costs.

The study attempts to elucidate the problem of the management of snakebites and envenomations in rural areas. It aims to assess the management of snakebite cases in the Bonginda group in Equateur, DR Congo. A survey was conducted during the period from January 2019 to December 2020. In addition, doctors from the Bonginda Health Zone, traditional healers and a few resource persons such as herbalists and people who have been treated for cases bites were contacted. The nature of the retrospective study required the administration of a questionnaire to those involved in the investigation. These include traditional healers and doctors from the health structures of the General Reference Hospital of Bikoro, Ntende, Moheli, Iyembemoke and Momboyo. The healing score recorded by traditional healers in the event of envenomation is estimated at 93.94% against 23.94% in medical structures. The low score recorded in the latter would be justified by the lack of an appropriate protocol for the specific cases thus diagnosed on the basis of modern equipment. Thus, the care provided by traditional healers seems more effective.

Introduction: The garrafadas, mixtures of plants with medicinal purposes conveyed in alcoholic beverages, do not have regulation and, for being presented with many therapeutic indications and no contraindication, they can be risky for the population. Methods: For this reason, the objective of this study was to evaluate the Brix degree°, evaluate the presence of pathogenic microorganisms, analyze the chemical characteristics pH and mass spectrometry (FT-ICR MS) and evaluate the label of syrup samples and garrafadas suspicious of adulteration seized by police. Results: The degree Brix° value of the samples was within the standards. The chemical analysis of the pH of the garrafadas and syrups samples obtained acid pH values, which can cause chemical instability on the components. Through the mass spectrometry, it was possible to detect some fragments of compounds related to the plants described on the labels, and no synthetic chemicals or drugs of abuse were found. The result of the microbiological evaluation detected Staphylococcus spp. in 4 samples, and, in 2 syrups, fungus growth occurred, beeing for fungi the growth were within limits established in the Farmacopeia Brasileira for this microorganism. In only four of the twelve samples evaluated, it was possible to detect mass fragments related to chemical substances of the plants described on the labels of the packages and most of them was made up of sugars only. Conclusions: Based on the results found, these products are not safe for consumers, as there is no way to guarantee their safety and efficacy.

Nowadays, cattle breeding is a major economic issue throughout the world. However, gastrointestinal nematode parasitism remains a major sanitary threat on a global scale, affecting animal health, farm productivity and the well-being of farmers. Until recently, chemical anthelmintics occupied a prominent place in the fight against these parasites. But some of them have developed resistance to antiparasitic drugs. The objective of this study is to compare the anthelmintic effects of commercial albendazole (8.3 mg/kg body weight) and annual mugwort (Artemesia annua, 100 mg and 150 mg) powder on gastrointestinal roundworms in cattle. Lots of animals were formed in a population of 92 animals, and underwent different treatments: with albendazole and with annual mugwort powder. The results showed that the artemesia annua powder has a strong inhibition on the nematodes but failed to eliminate them completely. Albendazole, for its part, showed a very effective effect with a 100% elimination of nematodes. These results highlight the possibility of using annual mugwort as an alternative to albendazole on farms.
