The limited integrated mathematics teaching materials focusing on discussing reasoning are one in learning mathematics problems, especially in preparation for integrated mathematics Olympiads. This study aimed to develop teaching materials for mathematical reasoning abilities integrated with religious values and students' attitudes towards mathematics integrating religious values. This research method is the ADDIE model development research method. At the implementation stage, the teaching materials were tested on research samples from MAN in the Regency and City of Sukabumi, with 76 students as research subjects. The sampling technique was purposive sampling—implemented through the Schoology application. The study results are as follows: teaching materials in integrated mathematical materials and questions to improve critical, creative, and adaptive reasoning skills towards religious values have good results and need to be developed more broadly than various materials with the separate presentation of mathematical material, teaching materials can improve critical, creative, and adaptive reasoning abilities with good results with an average score using module 60 and without module 52 with a maximum score of 100. Students' attitudes towards learning this integration method are in a suitable category. Integrated mathematics learning provides new experiences for students because learning mathematics is accompanied by learning to understand the contents of the Qur'an verses.

Authors: Kubik Joanna , Pawlak Kamil
Published: May 2023

The process of epithelial-mesenchymal transition (EMT) occurs in both physiological and pathological states, and there are increasing links between EMT and tumor progression. During this process, dynamic changes in cell organization and function occur that promote migration and invasion. A better understanding of the mechanism of plastic EMT may help develop novel targeted therapies that can help treat cancers of varying degrees of malignancy. Our review helps to systematize knowledge of the molecular and biochemical mechanisms involved in the EMT process in both tumor and physiological backgrounds.

Published: May 2023

The study aimed to discover the role of vitamin D in improving the respiratory function in sickle cell disease patients. In this prospective study, 188 adults were enrolled, drawn from the out-patients unit of Thalassemia Cente The collected data were categorized into three groups: group 1 included the data of 100 healthy individuals of age range of 18-50 years as control; group 2 included the data of 88 (40 males and 48 females) sickle cell disease patients in steady state before supplementation of vitamin D; group 3 represented the data of the same 88 sickle cell disease patients as measured and recorded after 6 weeks of vitamin D supplementation. Laboratory measurements including pulmonary function tests and hematological parameters, while vitamin D levels were estimated for all groups to compare the data before and after supplementation of vitamin We found significant differences in the pulmonary function tests when comparing groups. Mean value of FEV1 revealed significant differences between group 1 and 2 (p >0.05), while vitamin D supplement created a significant difference between group 2 and 3 (p >0.05). The improvement in FEV1 did not reach to that of healthy (group 1), as referred by the significant variation between group 1 and group 3 (p>0.05). The same findings were indicative within most pulmonary function tests, and the percentages of combined cases (restrictive and obstructive) were also deceased in group 3. Conclusion: supplement of vitamin D in SCD patients could result in relative improvement in lung function.
Communal Holiness in the Liberation and Methodist Movements
Authors: Highfield Kevin
Published: May 2023

In this article, aspects of the Methodism tradition are put in dialogue with characteristics of Latin American liberation theology to explore communal holiness. The article focuses primarily on the words of John Wesley and Gustavo Gutiérrez, considered founders of these movements. The Wesleyan ‘means of grace’ by ‘works of mercy’ is a similar concept to Liberation's ‘encountering God in the poor and oppressed.’ Traits of liberation spirituality are compared to Methodism. The concluding section asserts that in order to be sanctified (made holy), Christians must do it together. This holiness can be activated through works of mercy with the poor and oppressed.

Published: May 2023

Alzheimer’s disease (AD) is a devastating neurodegenerative disorder and the most common cause of elderly dementia. One of the main features of AD diseased brain are amyloid plaques, pathological depositions made of β-amyloid peptide, derived from β- amyloid precursor protein (APP). To assess how AD pathology affects synapses in the hippocampus, brain region to be one of the earliest with obvious pathological changes, we examined APPPS1 mice, transgeneticaly expressing human APP mutation (“Swedish mutation”) and human presenilin-1 mutation under the neuron-specific promoter, which develop AD symptoms early in life. We analyzed inhibitory and excitatory synapses using immunoflourescent staining and laser scanning confocal microscopy. In APPPS1 mice, inhibitory synaptic terminals labeled with vesicular inhibitory transmitter transporter (VGAT) were reduced in CA1 and CA3 regions of the hippocampus in APPPS1 mice compared to controls. This was true for both parvalbumin-positive and parvalbumin-negative terminals. On the other hand, excitatory synapses, coming from either hippocampal or entorhinal projections were similar between the genotypes. We conclude that first changes in the hippocampus caused by amyloid pathology affect inhibitory, but not excitatory synapses.

Published: May 2023

Цель работы – оценка риска деградации лесных геосистем под воздействием загрязнения атмосферы (по данным съемки TROPOMI Sentinel-5P). Как индикаторы риска использованы содержания SO2 и NO2, измеряемые TROPOMI. Район исследований – восточная часть Белорусского Полесья. Определены фоновые значения содержаний SO2 и NO2 в летний период. Изучены особенности загрязнения атмосферы SO2 и NO2 в сельскохозяйственных, сельскохозяйственно-лесных и лесных ландшафтах. Установлено, что динамика SO2 преимущественно определяется трансграничным переносом. Аномалии повышенного содержания NO2 приурочены к крупным техногенным геосистемам. Риск деградации лесных ландшафтов под воздействием загрязнения атмосферы оценивается как очень низкий (80/3% территории) и низкий (19/7% территории).

Published: May 2023

This paper discussed the method of navigation and robot formation in a swarm using the Local Positioning System (LPS) which was applied to the mobile robot's differential steering platform. Navigation and formation of robots in swarm robotics could run well because of the presence of robot position coordinates. In the outdoor application of coordinates, the position of the robot could be obtained easily using the Global Positioning System (GPS), but GPS had drawbacks in indoor applications. In indoor use, signals from satellites were difficult to obtain and inaccurate for use with relatively short distances. In coordinate research, positioning used LPS which was built using Bluetooth Low Energy (BLE). LPS with BLE was successfully built with simple resources and at a low price but had optimal performance. The LPS accuracy built with BLE and the regression algorithm had an error of 4.33% on the X-axis, and 2.67% on the Y-axis. The robot formation utilized a combination of proximity sensors and position coordinates obtained from LPS. The proximity sensor served to detect obstacles that hold the robot towards a predetermined target. The combination of navigation algorithms and swarm formation robotics was proven to be faster at finding targets compared to a single robot.

The grounding system design of the 150 kV substation have resolve affect in lightning strike area. The purpose of this study is to determine the duration of the potential difference penetration that occurs due to direct or indirect lightning strikes. The parameter method grounding system uses a combination of  R and L for the grid section and a combination of RLC for the rod section. Simulations due to direct lightning strikes in nearby areas greatly affect the spike in the amount of potential difference. The potential difference in the area closest to the lightning strike with a maximum surge of 57.42 V with a neutralization duration of 0.21 μs. At the furthest distance from a lightning strike, the maximum potential difference spike is only 3.14 V with a neutralization duration of 2 μs. The average duration of neutralization due to lightning strikes is 2 μs. In the simulation of a direct lightning strike striking electrical equipment, it causes a very high potential difference spike in lightning strike area of ​​992.96 V with a spike duration of 0.012 μs. The farthest area point at the location of the lightning strike has a spike of 31.07 V with a spike duration of 0.06 μs. The duration of neutralization at a potential difference below 1 V, has a duration of more than 2 μs depending on the distance from the location of lightning strike. The grounding system design is able to perform good performance with a fast potential difference neutralization duration in the event of a direct or indirect lightning strike. Lightning strikes that occur will not cause dangerous step and touch voltages for personnel in the 150 kV substation area.

Authors: Ofori Charles , Robert Ofosu  , Ametepe Ernest Atsu
Published: May 2023

The electricity access rate in Niger is one of the worst in Sub-Saharan Africa and is an issue of paramount importance to the Government of Niger. This energy insecurity has negatively affected industrialization and developmental plans, making Niger one of the poorest countries in the world. With a large landmass and several pockets of habitation in Niger, mini-grids remain the optimal way of providing electricity to people living in rural areas. Nigerienne Agency for the Promotion of Rural Electrification (ANPER), which is the institute responsible for rural electrification, currently operates about 110 diesel-powered mini-grids in Niger. With global warming looming, the operation of these diesel generators is not only expensive but also has an adverse effect on the environment. This paper seeks to analyze the techno-economic feasibility of a hybrid system for rural electrification in Niger with Sekoukou village as a case study. Load assessment, component technical configuration and component cost are simulated in HOMER software as objective functions to find the optimal size and cost. Results show that the most economical and efficient system for mini-grid operation in Sekoukou in Niger, is the generator-photovoltaic (PV) hybrid mini-grid which produces a levelized cost of energy of $0.271. A load shifting approach is applied to the existing load profile, which further reduces the levelized cost of energy from $0.271 to $0.177. This hybrid mini-grid system coupled with the load shifting approach would help improve the village’s ability and willingness to pay for electricity.

Published: May 2023

This paper aims to design a semi-circular patch microstrip antenna that can work at a frequency of 2.4 GHz (band 2360 MHz - 2400 MHz) to support Wireless Body Area Network technology (WBAN). One of the devices connected to WBAN technology is a Holter monitor and medical data recorder that forms a medical network for post-operative or monitoring ICU patients (Intensive Care Unit). To support one of the WBAN technologies, an antenna is needed that has considerable gain and bandwidth characteristics. To increase the gain and bandwidth, the array method is used on antennas with inset feed unification. The antenna design was simulated using CST Studio Suite 2019. The use of array methods on microstrip antennas can increase the gain by 132.9%, which is 5.73 dB. The simulation results obtained a return loss of -17.223 dB with a bandwidth of 88.3 MHz in the frequency range of 2357.6 MHz - 2445.9 MHz

Published: May 2023

As a very large archipelago country, Indonesia has a high intensity of the natural disaster. In many cases, the telecommunication infrastructure collapse during the disaster. Therefore, a prominent and robust emergency telecommunication network is required. In this paper, an implementation of VoIP services over the WiMAX-WLAN integrated network is proposed. The integrated network is designed to provide an alternative of the emergency network during the disaster response. The VoIP service is selected for the study case because this service can be used as a complementary of the telephony service. In this paper, the WiMAX network is designed based on the IEEE Standard 802.16-2004 with the frequency band of 3.5 GHz while the WLAN network is designed based on the IEEE Standard 802.11n. To support many scenarios of network topology, the proposed integrated network is designed in P2P and PMP topologies. Within these network topologies, the network performance is evaluated in terms of delay, jitter, throughput and packet loss, as well as MOS value. The network performance is evaluated over various background traffic. From the experimental evaluation, it shows that the network becomes worse when the network load that is represented by the background traffic exceeding 3 Mbps. In general, there is no significant performance different between P2P and PMP network topology.

Published: May 2023

Chronic respiratory diseases (CRDs) are highly prevalent in low- and middle-income countries. In Africa, the burden of CRDs is set to worsen due to an increase in smoking prevalence and household air pollution. Chest physiotherapy (CP) and pulmonary rehabilitation (PR) are used to manage CRDs in Africa, but distinguishing between these terms is not clear common among health-care professionals (HCPs) and patients. Here, we provide clarity on the differences between PR and CP to facilitate a greater understanding of PR and remove barriers to research and implementation of PR across Africa. CP is a treatment aimed at clearing secretions within airways of the lungs, while PR, through exercise training, education and self-management, treats extrapulmonary or systemic impairments. We know that there is a need for PR among people living with CRDs in Africa. However, health professionals’ knowledge and training in PR remains insufficient. To implement PR services for people with CRDs in Africa, a strong understanding of what PR is, and its evidence base are needed. The development of PR in Africa will start by filling the gaps in knowledge, awareness, advocacy, and training.

Evaluating Corporate Social Responsibility Reporting Practices in the Sultanate of Oman (2016 to 2018)
Authors: المعولي Sultan Said
Published: May 2023

This study evaluates corporate social responsibility (CSR) reporting practices in the Sultanate of Oman by investigating how stakeholders perceive CSR reporting and practices in different sectors. Moreover, it examines if there is a difference in CSR reporting practices across different sectors over three years, from 2016 to 2018 inclusive. A quantitative multi-method is used in this study to address the objectives and the questions of this research. Overall, the analysis shows that the level of CSR reporting in Oman is moderate in terms of both the stakeholders’ views and the annual reports of the companies. Furthermore, both the stakeholders’ views and the report analysis show a match in the results. Therefore, this result supports the stakeholder theory, which states that companies should make decisions that meet the interests of stakeholders, which includes economic, environmental and social dimensions. Finally, the researcher has two recommendations based on these study findings. Firstly, Oman needs legislation on CSR since there is no legislation to date that defines organizing CSR in Oman. Secondly, Oman needs to give greater attention to spreading awareness to all stakeholders of their power in many corporate activities.
دور المستشار البريطاني تشارلز بلجريف في تأسيس دولة البحرين الحديثة: دراسة تاريخية (1926 - 1957)

تهدف هذه الدراسة إلى الكشف عن دور السير تشارلز بلجريف، المستشار البريطاني لحكومة البحرين (1926 – 1957)، في تأسيس دولة البحرين الحديثة استنادا إلى الوثائق التاريخية. كما تهدف الدراسة إلى الكشف عن آليات اتخاذ القرار السياسي في أثناء فترة عمل السير تشارلز بلجريف في البحرين، وربط القرارات التي اتخذها المستشار البريطاني بالمتغيِّرات والمستجدات الداخلية والخارجية. وقد استندت الدراسة على مجموعة من المصادر التاريخية، وخلصت الدراسة إلى أن تشارلز بلجريف لعب دورا سياسيا إيجابيا في بناء دولة البحرين الحديثة، وأنه كان، بصفته مستشارا، موظفا حكوميا لم يتصرّف إلا بإذن مسبق من السلطة الحاكمة، غير أن الصلاحيات الإدارية الواسعة التي مُنحت له في تسيير شئون أجهزة الدولة جعلته يعتقد أنه يمتلك السلطة المطلقة في اتخاذ القرار. أضف إلى ذلك أن القرارات التي اتخذها تشارلز بلجريف لم تكن في أغلب الأحيان فردية وارتجالية، بل جاءت ثمرة لتفاعل تأثير القوى الداخلية، مُمثلة في سلطة الحكم بالبحرين، وقادة الحركة الوطنية البحرينية في منتصف القرن العشرين، والقوى الخارجية، مُمثلة في قوى الاستعمار البريطاني في منطقة الخليج العربي.

The twenty-first century is witnessing an increasing and clear interest in studying the relationship between student teachers’ motivation and their participation in professional development programs. This study was designed to find out the student teachers’ motivation toward participation in professional development programs and to identify the role of motivation in influencing the ambition, perseverance, and desire of student teachers to be effective and active in carrying out activities and tasks. The descriptive survey design was employed, 75 student teachers were chosen to participate, and data were collected using a developed instrument after ensuring its validity and reliability. The results of the study showed that the level of student teachers’ motivation toward participation in professional development programs was very high and that they are aware of the fact that professional development programs are the most effective means for developing their ambition, perseverance, and desire to participate in activities and tasks. Based on these findings, a set of conclusions and recommendations were drawn. Doi: 10.28991/ESJ-2023-SIED2-06 Full Text: PDF
Clarifying the biological nature of the interaction between the systems-based epigenetic landscape and the epigenome
Authors: Caldú-Primo José Luis , Dávila-Velderrain José , Martínez-García Juan Carlos , Álvarez-Buylla Elena R.
Published: May 2023

The epigenetic landscape concept initially proposed by Conrad H. Waddington has become a powerful tool to quantitatively address constraints underlying cell differentiation and morphogenesis. In theoretical and experimental terms, this has been enabled by grounding gene regulatory network models on experimental data. Such models have, in turn, led to proposing epigenetic landscape models that entail functional and structural constraints of cell differentiation and morphogenetic dynamics, and thus the understanding of development from a systems–based perspective. Therefore, it is mainly in the context of the study of development where the epigenetic landscape has been anchored as a conceptual support. On the other hand, nonetheless, given the recent understanding of gene control by epigenomic modifications and the capacity to profile these modifications using high– throughput molecular techniques, the notion of epigenetics has been mainly related to non-genetic heritable modifications of the genome. Therefore, this approach, which until now has not been based on a systems–based dynamical treatment, has given proximal epigenomic modifications a central role in understanding development. The latter, has left the dynamic view of epigenetic landscape aside. In this paper we aim at establishing a conceptual link between both conceptualizations of epigenetic regulation.
Uncovering the particularities of the dynamical interaction between cancer-related Epithelial-Mesenchymal Transition and the Mammalian Cell Cycle: a feedback-based Boolean networks interconnection approach

Published: May 2023

Epithelial-to-Mesenchymal Transition (EMT) plays a key role in epithelial-cancer. The state trajectory of its underlying Gene Regulatory Network (GRN) includes three fixed-point attractors characterizing epithelial, senescent, and mesenchymal, cell phenotypes, which implies specific cell-to-cell and cell-to-tissue interactions. The interplay between the GRN driving EMT and the one regulating the Mammalian Cell Cycle (MCC) influences cancer- related cell growing and proliferation. We expose the characteristics of the network arising from the interconnection of the gene regulatory networks associated to EMT and MCC. Our purpose is twofold: first, to elucidate the dynamical properties of cancer-related gene regulatory networks. Subsequently, to propose a computational methodology to address the interconnection of networks related to cancer. Our approach is based on feedback-based interconnection of networks described in discrete Boolean terms.
Utilizing Functional Annotation of Disease Genes for Disease Clustering
Authors: Al-Mubaid Hisham , Aldwairi Tamer
Published: May 2023

We investigate the task of disease clustering with the functional annotations of disease genes from the Gene Ontology using the biological process aspect. As an unsupervised machine learning step, the clustering task places communities of similar diseases together based on their closeness to one another using functional annotations of their associated genes. The research work and studies for the similarity, relationship, or clustering of human diseases using the functional information associated with the disease genes are limited. This work builds on and benefits from the advances in gene disease association studies; also from the advances in the functional annotations of human disease genes from the Gene Ontology. We validated the experimental results by comparing the intra-cluster and inter-cluster disease similarity with their semantic similarity in the is-a hierarchy in both MeSH and DO disease ontology. The experimental results are highly encouraging and show that we can rely on the functional profiles using the biological process annotations of disease genes for the study of disease clustering and similarity.
On the Partition of Space by Hyperplanes
Authors: Bagdasaryan Armen
Published: May 2023

We consider the problem of partitioning of space by hyperplanes that arises in many application areas, where the number of regions the space is divided into is required to be determined, such as speech/pattern recognition, various classification problems, data analysis. We obtain some relations for the number of divisions and establish a recurrence relation for the maximum number of regions in d-dimensional Euclidean space cut by n hyperplanes. We also re-derive an explicit formula for the number of regions into which the space can be partitioned by n hyperplanes.
TIME OVERRUN AND ITS IMPACT ON COST OF CONSTRUCTION OF SMALL HYDROPOWER PROJECTS IN NEPAL
Authors: Thapa Suman , Mishra Anjay Kumar
Published: May 2023

Hydropower is one of the main sources of energy that can be produced as green energy highlights the timely complementation of construction projects. The study is focused to assess the causes of time overrun and its impact on the cost of construction of small hydropower projects in Nepal. The study is based on pragmatic philosophy using case study and survey along with document analysis using correlation and financial decision tools. The result of the study found that all sample projects were facing time overrun. Only 30 % of the cost was due to time increment. Along with time overrun direct cost was negatively related and the indirect cost was positively related, the direct cost was more significant than the indirect cost of the hydropower project resulting in the total cost being negatively related to time increment. Profitability was decreased due to time factors though it was positive till other factors were not impacting. The research concluded that social issues and land problems were the main cause of time overrun which was not properly addressed at the time of planning. Time overrun had become the norm rather than the exception on projects. Time was a partial factor of cost overrun causing it to reduce in its profitability. Besides time, another factor which was causing the cost overrun is to be identified and control for cost overrun. The developer should focus on reducing the direct cost using advance purchase agreement as of schedule and specific care should be taken for social demand. Methods of time allocation of contract should be estimated based on activities using theory of constraints for assuring timely completion and profitability of hydropower projects.

Published: May 2023

Background: Arterial catheters are commonly used in acute care units for hemodynamic monitoring in conjunction with blood pressure and blood gas analysis. Complications arising from the use of arterial catheters have been reported; however, few studies have focused on standard practice of arterial catheters.
Aim: To clarify the management, particularly the insertion frequency and timing, of peripheral radial arterial catheters in acute care units in Japan.
Methods: We developed 34 questions through an interactive process based on guidelines and clinical experience to create a digital survey. This survey was conducted over a month. Participants were nurses working in acute care units in Japan who received electronically distributed surveys through nursing-specific mailing lists and social network services.
Results: A total of 451 responses were collected; 224 were used for analysis. Respondents reported 35% implemented routine insertion of arterial catheters for all newly admitted patients, while 58% would insert the arterial catheter within 24 hours of admission.  Only 7% of respondents did not add heparin to the pressurized bag. Of the respondents, 51% had a rule to change the pressurized bag of fluids every 3 days. Splinting of the wrist was a routine procedure for 41% of respondents.
Conclusions: Arterial catheters were commonly used in all acute care units.  Based on the results of the survey, we recommend the use of heparin as a flush fluid should be reconsidered. The high rate of unnecessary arterial catheter insertions and the routine use of splinting need to be reassessed.

Published: May 2023

Background
In 2022, after two and a half long years of caring for COVID-19 patients on the frontlines, critical care nurses were burnt out and leaving the bedside. Aim To reinvigorate critical care nurses, a large multisystem healthcare organization’s Nurse Scholars Academy partnered with Springer Publishing to offer a dynamic self-paced online review course for the critical care certification exam.
Methods
Recruitment strategies for all regional critical care departments were implemented through education departments at each facility. Springer Publishing would provide participating nurses with access to the self-paced study program on ExamPrepConnect. The Nurse Scholars Academy would provide a prepaid certification exam voucher at no cost. In exchange, participants would commit to take the certification exam within 3 months of Pilot kick-off.
Results/Findings By month 4, 70 nurses took the Adult CCRN® certification exam. Of those 70 who took the exam, 58 passed. The pass rate was 82.8%, 11.3% above the national pass rate of 71.5% (AACN, 2021). Nurses spent more than 1,500 hours studying in ExamPrepConnect and successful ExamPrepConnect users studied for an average of 19 hours. Conclusions. The pass rate was a successful outcome. The overwhelming response from local critical care nurses who wanted to obtain their critical care certification was encouraging. The need was apparent, and the resources were there. Of note, only 30% of those participants took the certification exam, future implications for this study involve further brainstorming on effective promotion to improve awareness and support frontline staff to take full advantage of these unique programs.
