Intelligent Student Relationship Management Platform with Machine Learning for Student Empowerment
Authors: Issaro Sasitorn , Wannapiroon Panita
Published: February 2023

Students’ grades can affect their future studies at university. The COVID-19 situation has resulted in a greater amount of online teaching, in which teachers and learners rarely interact, causing additional problems with academic performance. This research aims to design and develop an intelligent student relationship management platform (an intelligent SRM platform) using machine learning prediction for student empowerment. This research begins with the synthesis of the factors, the machine learning prediction process, and the platform components. The results of the synthesis establish the design of the platform. Undergraduate students’ grades are then predicted using the decision tree algorithm. Students are divided into two groups, empowerment and non-empowerment groups, using this algorithm. The results show that the learning outcome prediction model has an accuracy of 100.00% and an F-measure of 100%. The most important factor for improving grades is the grade point average, with a weight of 0.637. Therefore, student empowerment to provide students with better grades is essential. This paper presents two approaches to student empowerment: using artificial intelligence technology from the intelligent SRM platform and empowering teachers.

Teaching Knowledge Sharing in Virtual Practice Teaching
Authors: Wang Li'e , Liu Fenshan
Published: February 2023

Physical education, skill training and other related courses with physical exercises and experience training as the main means are suitable for teaching with virtual reality technology. Constructing teaching knowledge sharing strategy can promote the sharing of virtual practical teaching resources among students. At present, no scholars have paid attention to how to promote the exchange of ideas and experiences among students participating in virtual practical teaching, so that teaching knowledge can spread among students faster and more effectively. Therefore, this article studies the teaching knowledge sharing method of virtual practice teaching and constructs BiLSTM-Attention relation extraction model to recognize named entities of teaching knowledge resources in virtual practice teaching, to record the information of knowledge points involved in teaching knowledge resources, and to explore the information hidden in knowledge resources more deeply. This article constructs a knowledge sharing model of virtual practice teaching based on traditional evolutionary game, and analyzes the local stability of the model based on Jacobin Matrix. Experimental results verify the effectiveness of the model.

Published: February 2023

The daily functioning of civilization depends heavily on transportation. In most cities, a sizable section of the working class consistently attends both employment and education. There are many different things you can do when commuting, such as unwinding, eating out, and other things. The most popular means of transportation in North Cyprus, particularly in developing cities, is island transportation, which includes the usage of both private cars and commercial vehicles. The advent of edge computing, which offers the opportunity to connect potent processing servers next to the mobile device, is a significant step toward improving user experience and reducing resource use. Mobile Edge Computing is the next trustworthy approach for how mobile devices consume communications and computing. Offloading computation is a key component developing mobile edge computing, which enables devices to get around clustering techniques' limitations and get around computing, storage, and energy constraints. However, computation offloading is not always the best strategy to use; making choosing unloading is a critical step that requires consideration of numerous factors. For instance, shifting the high-resource node to an edge server and granting similar capabilities to the low-resource nodes would delegate heavy duties to the external unit inside the network. The evaluations' results were noteworthy and substantial. Problems involving the vehicles of institutions and organizations can be resolved using the suggested solution to the school bus routing issue. We also test the impact of network latency on the delivery of a particular result using an Edge Computing simulator.
Exploring the overshadowed streams of the Red Cross Movement
Authors: Miyagawa Mayuka Tamura
Published: February 2023

This ePaper explores the endeavours and motivations of the leading figures of the Japanese Red Cross Society, which forms the streams of the Red Cross Movement that get overshadowed in the Eurocentric narrative of its history. Using various primary sources from archives and studying the historical context of the time, the paper highlights how the main protagonists with similar backgrounds to the founders of the International Committee of the Red Cross proactively sought to establish and develop the movement both at the national and international level from 1867 to 1919. Moreover, a close examination of their backgrounds as well as their thoughts as expressed in their writings suggests that their motivations to engage in Red Cross work were multiple and in part, if not entirely, shaped by various needs to fulfil their own desire and sense of obligation. We extend our heartfelt thanks to the Vahabzadeh Foundation for financially supporting the publication of best works by young researchers of the Graduate Institute, giving a priority to those who have been awarded academic prizes for their master’s dissertations.

Congenital long QT syndrome
Authors: Santi Aura Daniella , Restrepo Miguel
Published: February 2023

The diagnosis of long QT syndrome (LQTS) in utero presents many challenges for clinicians, and there is high risk for intrauterine fetal demise as life-threatening arrhythmias develop secondary to QT prolongation. We describe a challenging case of a fetus presenting with sinus bradycardia and second-degree atrioventricular block with episodes of ventricular tachycardia. A prenatal diagnosis of LQTS was suspected given the fetal echocardiographic findings of a short ventricular relaxation time, due to extremely prolonged refractory period. The patient was delivered emergently due to Torsade's with hydrops, with ongoing arrhythmia despite medical management requiring implantation of pacemaker and sympathectomy. Early recognition of LQTS is important to optimize fetal survival with prompt medical management.

Published: February 2023

Background:

Vasoactive medications are frequently used in the preoperative stage to balance the pulmonary and systemic blood flow. However, not much is known about the effects of these agents during this stage.

Aims:

The primary objective of this study was to characterize the acute effects of vasoactive medications in children with parallel circulation before either the hybrid or Norwood procedure.

Setting and Designs:

This is a single-center, cross-sectional, retrospective study.

Methods:

Hemodynamic and systemic oxygen delivery data were captured from patients’ vital signs, arterial blood gases, near-infrared spectroscopy monitoring (NIRS). Data for each patient were collected before the initiation of a vasoactive medication and again 6 h after.

Statistical Analysis:

Data were analyzed using paired t-tests, and analysis of covariance.

Results:

A total of 139 patients were identified. After data extraction the following patients were included before the initial intervention: 7 were on milrinone, 22 were on dopamine, and 17 were on dobutamine. Dopamine and dobutamine were found to significantly increase systolic blood pressure. Only dopamine increased pH (mean difference 0.04), decreased paCO2 (mean difference -7.1), decreased lactate (mean difference -0.6 mmol/L), and decreased in bedside Qp: Qs (mean difference -7.5) after continuous infusion for 6 h. Milrinone was not associated with any significant hemodynamic change.

Conclusion:

In this study, dopamine was independently associated with improvement in markers of systemic oxygen delivery 6 h after initiation. Dobutamine and dopamine were associated with increased in blood pressure. Well-powered studies are required to detect changes in lactate and NIRS.

Published: February 2023

Burkitt's lymphoma (BL) is a highly aggressive type of B-cell non-Hodgkin lymphoma. BL commonly occurs in children of age 4–7 years and is uncommon in adults, with a worse prognosis. Patients often present with a rapidly growing mass typically involving the abdomen (liver and spleen) and head and neck (nodes, jaw, and facial bones). Pancreas involvement is very rare and very few case reports have been documented so far. Fluorine-18 positron emission tomography/computed tomography (F-18 PET/CT) is a whole-body survey commonly used for initial staging evaluation. Here, we present an interesting case of BL in an adult female of 43 years, who presented with swelling in the left submandibular region after tooth extraction with multiorgan involvement found on F-18 fluorodeoxyglucose PET/CT.
Extensive Metastatic Vascular Calcification in a Patient with Chronic Renal Failure and Tubercular Osteomyelitis as Seen on F-18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography
Authors: Prakash Sneha , Damle Nishikant Avinash , Sethi Prayas , Jana Manisha
Published: February 2023

A 48-year-old male with known tubercular osteomyelitis of the left elbow and chronic renal failure presented with PTH independent hypercalcemia and underwent F-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) to look for any underlying malignancy that might be causing his hypercalcemia. The PET/CT did not reveal any malignancy, but extensive metastatic calcification of small- and medium-sized arteries was noted throughout the body with relative sparing of large vessels. Alkaline tissue such as lungs, gastric mucosa, and kidneys that are usually involved in metastatic calcification were also spared. The underlying pathology for this kind of metastatic calcification was most likely chronic granulomatous disease, which was tubercular osteomyelitis in this patient. We present the PET/CT scan images of this unusual case of metastatic vascular calcification.

Published: February 2023

Skeletal scintigraphy is one of the most widely performed investigations in any nuclear medicine department. However, there has been a paradigm shift in the indications for which bone scan was performed in the past 3 decades, mainly due to advancement in other imaging modalities, better disease understanding, and the development of newer disease-specific guidelines. The metastatic indications for bone scans accounted for 60.3% of cases in 1998 which reduced to 15.5% in 2021 and nonmetastatic indications rose from 39.7% in 1998 to 84.5% in 2021. Fewer bone scans are being performed for the metastatic survey, and more scans are being performed for nononcological orthopedic and rheumatological indications. This article captures the journey of skeletal scintigraphy in the past three decades.

Published: February 2023

Ectopic thyroid tissue can be present in the embryonal path of descent of the thyroglossal duct anywhere from the foramen caecum to the thyroid gland. However, for such ectopic thyroid tissue to be hyperfunctioning is quite rare. Here, we discuss a 56-year-old female patient who presented with persistent thyrotoxicosis for over 7 years. She had undergone thyroidectomy in 1982 for thyrotoxicosis and was rendered hypothyroid (thyroid-stimulating hormone of 75 μIU/mL). Whole-body technetium scan was done twice which did not show any uptake in the neck or other parts of the body and an empirical dose of 15 mCi of radioiodine therapy was also given to treat the thyrotoxicosis. She continued to be thyrotoxic and was on carbimazole 30 mg/day along with beta-blockers. In 2021, an Iodine131 whole-body scan revealed small remnant thyroid tissue and an ectopic thyroid tissue in a thyroglossal cyst. In such cases of persistent or recurrent thyrotoxicosis despite standard treatments, an ectopic location should be sought after and treated.

Authors: Raman Praveena , Pitty H. Raghuram
Published: February 2023

Background:

Recurrent aphthous stomatitis (RAS) is a common inflammatory condition affecting the oral mucosa causing interference with mastication and speech with significant impact on quality of life. The use of topical steroids remains the mainstay as the primary therapeutic approach and they are often considered to be the first choice of treatment. Turmeric has been used in the Indian traditional medicine for centuries. Its anti-inflammatory and wound healing activities are demonstrated by the rapid healing of the ulcers.

Aim:

The primary aim of this study was to assess and correlate pain score with ulcer size using topical curcumin 2% gel and triamcinolone acetonide oral paste 0.12% in recurrent minor oral aphthous ulcerations.

Methodology:

Following convenient sampling, 60 volunteered students with oral aphthous ulcers were included to take part in this single-blinded randomised study. Randomization was done by flip coin method. Group I received Topical Curcumin oral gel 2% and Group II received Topical Triamcinolone acetonide 0.1%.

Statistical Analysis:

Qualitative data was expressed in percentage and quantitative in mean (SD). Independent sample t test and correlation was done.

Results:

The ulcer size was smaller initially and gradually increased in the next few days and the size decreased upon ulcer healing. Initially, the pain score was higher and gradually decreased as the ulcer healed. Positive correlation of ulcer size and pain score was obtained in Group I on the 1st day, 4th day and 5th day with statistical significance of P < 0.001 and negative correlation on 2nd day without statistical significance. Ulcer size and pain score in Group II was correlated negatively on Day 1, 2, 6 and 7 without statistical significance and positively correlated from Day 3-5 without statistical significance. Ulcer size and pain score was negatively correlated with statistical significance for Day 6 and 7.

Conclusion:

Our study showed that Curcumin performed on par with triamcinolone and there is no positive correlation between ulcer size and pain score with topical management of Curcumin and Triamcinolone in aphthous ulcers. Though both the drug was effectively able to bring down the pain and size without any side effects, with a borderline favorable result with steroid.

Published: February 2023

Mc Cune Albright Syndrome (MAS) is a rare, sporadic disorder characterized by a triad of symptoms: fibrous dysplasia, cafe-au-lait spots, and endocrinopathy. It is thought to be caused by the mutation of the GNAS1 gene and is predominantly a disease of females. We hereby report a case of a 40-year-old man who presented with suppuration and mobility of teeth in the maxillary left posterior region. The patient also had a history of recurrent fractures of limbs since childhood. Clinical examination revealed asymmetry of the face, brownish-tan macules on the nape of the neck, back, and bilateral buccal mucosa as well as lower labial mucosa. The radiological investigation confirmed the presence of polyostotic fibro-osseous lesion while the biochemical investigations revealed endocrinopathy (hyperparathyroidism). This case report emphasizes the role of an oral physician in arriving at the diagnosis of a complex disorder like MAS.

Published: February 2023

Aim:

To find out the normal mean oral temperature in the Indian population as per a longitudinal study.

Background:

98.6°F is generally accepted as normal body temperature as defined by Wunderlich (1868) and later challenged by Mackowiak (1992) and Protsiv (2020) who concluded it as 98.2°F based on cross-sectional studies. Hence, the normal body temperature at present needs quantification as per a longitudinal study in Indians.

Patients and Methods:

A longitudinal study on the healthy population of Northern India was followed-up over 1 year. Participants were advised for self-monitoring of oral temperature with a standard digital thermometer in either left or right sublingual pocket and record it in the thermometry diary. The study was considered complete if the participant had all three phases of the study (i.e., non-febrile, febrile and post-febrile phases) or completed the duration of the study.

Results:

The mean oral temperature of the participants (n = 144) during the non-febrile and post-febrile phases (temperature readings = 6543) were 98.0°F (standard deviation [SD], 0.61) and 98.01°F (SD, 0.60), respectively (P < 0.001). With the diurnal variability, the morning (am), noon (an) and afternoon (pm) mean temperatures were 97.91°F, 98.08°F and 98.27°F (P < 0.001), respectively, during the non-febrile phase. Similar trends were observed in variability among men and women, seasons and across post-febrile phase.

Conclusions:

The mean oral temperature was 98.0°F (SD, 0.61). The temperature was as low as 96.9°F and as high as 99.1°F. The temperature during the post-febrile phase was found to be higher than the non-febrile phase temperature such as pm over an and am, women over men, summer over other seasons in the non-febrile phase and spring over others in the post-febrile phase.

Authors: Sharma Jyoti , Sharma Rakesh , Negi Rashmi , Jelly Prasuna
Published: February 2023

Background:

The nursing process is an important tool that has transformed the standards of nursing practices. Application of the nursing process required proper training, guidelines and resources to be used by the nurses.

Aim:

The objective of this study was to assess the knowledge and practice of nursing process among nurses and explore factors influencing its applications by nurses.

Methods:

An exploratory, descriptive study was conducted among 210 nurses using a simple random sampling technique. A pre-designed, self-structured questionnaire on knowledge and practice of nurses regarding nursing process and factors influencing its application were used to collect data. The data were analysed using descriptive and inferential statistics.

Results:

Most of the nurses were female (60.5%), had General Nursing and Midwifery (76.2%) as professional education, working in general medicine units (52.5%) and had more than 5 years of professional experience. The mean knowledge and practice score regarding nursing process were 13.93 ± 5.204 and 6.51 ± 0.96, respectively. Major hindering factors were the absence of a format for recording nursing process, poor nurse–patient ratio and excessive workload and never attended in-service education on the nursing process. Many nurses reported working in a stressful environment and were dissatisfied due to excessive clerical paperwork.

Conclusion:

The majority of nurses had average knowledge of nursing process, but they were not practicing. Certain factors such as no format, in-service education and equipment supplies affected the nursing process application in clinical areas. Hence, it is recommended to modify the above factors for proper application of nursing process.

Verfremdungseffekt
Authors: Kolb Martina
Published: February 2023

Verfremdungseffekt (V-effekt), usually translated as alienation effect (a-effect), is a concept developed by the German poet, playwright, and dramaturg Bertolt Brecht (1898–1956). His V-effekt is a term of the arts, not of philosophy or sociology. Brecht’s Verfremdung distinguishes itself from Hegelian and Marxist notions of alienation (Entfremdung) by being relentlessly focused on the theatre and its political and aesthetic impact on roles, actors, and audiences.

Cultural Anthropology
Authors: Manganaro Mark
Published: February 2023

The development of cultural anthropology, which is the study of human culture and its variations, in the late 19th and early 20th centuries played a major role in Modernism. Anthropological accounts of tribal peoples, often termed ‘primitive’ or ‘savage’, fascinated modernist artists, who found in the anthropologists’ descriptions of tribal behaviours, social organisation, material culture, and ritual practices exciting and exotic alternatives to modern cultural beliefs, practices, and ways of making art. Writers such as D.H. Lawrence found in anthropological accounts of tribal peoples intuitive modes of perception and behaviour that were at odds with civilised, ‘rational’ ways of thinking and acting. T.S. Eliot and others found in the evolutionary anthropology of James Frazer, author of the renowned The Golden Bough, forms of belief and ritual that could inspire the development of new modern art forms. Furthermore, Eliot found in Frazer’s textual method of comparing and juxtaposing ‘primitive’ and ‘civilised’, and ancient and modern peoples the basis for a non-narrative way of organising modern art, the ‘mythical method’ he called it, which in one review he claimed formed the basis of organisation for James Joyce’s Ulysses and which, arguably, also helped to shape his own poetic modernist masterwork The Waste Land (Ulysses and The Waste Land were published in the same year, 1922). Moreover, tribal tools, ornaments, and religious/ritual objects brought to the West by anthropologists and traders became inspirations for, and as well the formal basis of, important early modernist visual art by Pablo Picasso, Georges Braque, and others. In general terms, cultural anthropology participated in and produced a societal urge for the ‘primitive’ in the modern culture of the early 20th century.
Hughes, Langston (1902–1967)
Authors: Haddad Vincent
Published: February 2023

Langston Hughes was one of the most accomplished, influential writers of the 20th century. Influenced by the inclusive ‘I’ of Walt Whitman and the musical styling of Carl Sandburg, his innovative poetic syncopation of the blues, jazz, and Negro spirituals became an emblem of the Harlem Renaissance, for which his poetry collections The Weary Blues (1926) and Fine Clothes to the Jew (1927) are pioneering texts. Hughes was first and foremost an American writer, in the truest sense of the word: his involvement in the leftist cultural resistance to overthrow racial oppression, along with his immensely popular works in translation, made Hughes hugely significant in Latin America for artists and intellectuals such as Nicolás Guillén and Claude McKay.

Jacob Glatstein, or Yankev Glatshteyn, was a Polish-born Jewish American poet, novelist, and literary critic who primarily wrote in Yiddish. Glatstein was born in Lublin, Poland, in 1896 and immigrated to the United States in 1914, settling in New York City. He joined the Yiddish literary community, and following the First World War, alongside Aaron Glanz-Leyeles and Nahum B. Minkoff, he established the Introspectivist movement, which emphasised the self. Glatstein made major contributions to Yiddish and American modernist poetry, particularly through his linguistic experimentation and by writing on topics of international concern. His writing reflected the cultural exchange driven by Jewish migration from Europe to the Americas and demonstrated the cosmopolitanism of Jewish immigrants and travellers.

Published: February 2023

The widespread use of unmanned aerial vehicles during warfare has intensified the problem of their management, especially when they are used in large groups. One of the main tasks is to ensure coordinated movement of the group's aircraft in space. Optimizing the movement of each device of the group in three-dimensional space is expedient to use mathematical models. The movement of any unmanned aerial vehicle can be presented as a combination of translational and rotational movements, and its speed as a combination of translational and rotational velocities. Previously, these movements were modeled separately using a system of differential equations or quaternions. In this article, a mathematical model of rotational and translational movements of an aircraft based on the algebra of dual quaternions is developed. Dual quaternions consisting of eight scalars are a compact representation of rigid transformations in space. Therefore, their properties determine the advantage in the course of motion simulation, as they reduce the amount of calculations. Thus, with the help of one dual quaternion, it is possible to provide both translational and rotational motions at once, and the operation of non-commutative multiplication of dual quaternions is used to simulate the movement.
The model assumes that the real part of the dual quaternion determines the orientation of the UAV in space, and the dual part determines its position in three-dimensional space. In order to connect aircraft coordinate systems with the model, expressions for the transition from aircraft orientation angles (roll, yaw, and pitch) to dual quaternion parameters and vice versa are obtained.
The functionality of the proposed model was confirmed using the developed software for modeling the coordinated movement of aircraft. The software is adapted for graphical display of a large number of aircraft in web browsers with WebGl support.
Keywords: motion modeling; rotational and translational movement; unmanned aerial vehicles; quaternions; dual quaternions; algebra of quaternions.

The presence of a significant number of strike systems of high-precision weapons at the enemy causes an urgent need to create effective systems for the protection of infrastructural and military facilities. One of the elements of such systems can be the forces and means of radio-electronic warfare, which will allow to carry out protective actions in the electromagnetic spectrum.
But in the current conditions of resource and time limitations, the involvement of electronic warfare means in such protection systems is a certain scientific and practical problem that needs to be solved, in particular, through the determination of the predicted effectiveness of their functioning in the system of object protection.
The article proposes an approach according to which the actions of high-precision weapons in the process of aiming them at objects and the corresponding measures of defense systems used against them are considered antagonistic, since they are performed both with the use of transmitting and receiving radio-electronic means of high-precision weapons, and protection systems. The use of radio-electronic warfare in operations in the electromagnetic spectrum to counter high-precision weapons is being investigated as a component of operations in the electromagnetic spectrum. To conduct the research, a tactical combat episode was considered, in which the accepted assumptions and limitations do not distort the content and physical essence of the processes of radio-electronic warfare with high-precision weapons.
It is proposed to evaluate radio-electronic warfare based on the probability indicator of disorganization of the high-precision weapon guidance system. It is shown that, in accordance with the accepted conditions, in the numerical definition, the indicator is limited by the probability of successful guidance, which is provided by an inertial system that does not require the organization of radio communication lines, and data transmission is carried out in the internal control loop.
The proposed indicator can characterize the use of electronic warfare forces and means in defense systems against high-precision weapons, since it depends on:
from the technical characteristics of samples of high-precision weapons (indirectly determines the immunity of the radio lines of their guidance systems);
from the capabilities of the forces and means of radio-electronic warfare with high-precision weapons.
Keywords: high-precision weapons; operation in the electromagnetic spectrum; electronic warfare; guidance systems.

Analysis of the use of unmanned aerial systems in the combat zone indicates a constant increase in the requirements for intelligence data. One of the ways to increase the effectiveness of UaV application is the use of artificial intelligence methods. The basis for building a reliable neural network model is a large amount of various data, which helps to more accurately summarize information about the given task. The article considers an approach for increasing the accuracy of object image classification by convolutional neural networks based on data augmentation, which differs from existing ones in its adaptation to shooting factors and the specificity of aerial reconnaissance objects.
An important and most time-consuming step in building an accurate machine learning model is finding and annotating the data that will be used to train and test the accuracy of the neural network. The accuracy and stability of the network in real conditions depends on the amount of collected data. To date, such methods of object image augmentation as geometric transformations, color correction, and spatial image filtering have been well described and analyzed. The possibilities of optimal combinations of data augmentation methods to achieve the desired generalization of poorly visible invariant features of objects remain unexplored at the moment. Taking into account the conducted research, an approach was proposed for the formation of a set of a priori data of a neural network for object recognition on digital aerial photographs, which will significantly reduce the complexity of the process of collecting the necessary data and replace it with magnification methods that are much simpler, consume less computing resources, and increase the accuracy of work convolutional neural networks, simulation of the use of the proposed approach was carried out.
Keywords: unmanned aerial vehicle; convolutional neural network; data augmentation; automated processing of digital aerial photographs.

Based on the increased interest on bank size in literature, we sought to investigate the effect of large banks on bank earnings volatility in Kenya banking system. Our data cover the period from 2005 to 2020. Included in our analysis is ROA volatility (ROE volatility) and market volatility, as measures of bank earnings volatility at bank level and at market level respectively. In addition, we used bank risk, at individual bank level and at market level, for further analysis in our model. Our findings have shown that bank size positively and significantly affect the bank earnings volatility as measured using ROA volatility, but an inverse and insignificant effect on ROE volatility. We also find that growth in bank size positively and significantly affect their individual risk exposure, but does not increase the market risk. Our findings have policy implications in considering optimal bank size, bank risk and systemic risk.

Introduction: Acute Respiratory Infections, (ARI), and diarrhea represent major leading cause to under five morbidity and mortality all over the world. Majority of these cases occur in the poorest communities. This study aimed to assess different home management practices of pneumonia and diarrhea in Sana’a.
Methods: This is a hospital-based cross-sectional study with direct interview of Mothers recruited from major hospitals in Sana’a between January and May 2020.
Results Two hundred and six mothers were enrolled in this study. Hundred and sixty-six (80.6%) of mothers in this study used over-the-counter anti-cough preparations. The study reported 58.7% of mothers did not give their children Oral Rehydration Solution (ORS), during diarrhea. We found 45.1% and 35% gave antibiotics without prescription during ARI and acute diarrhea respectively. Majority of mothers continued breastfeeding. No association was detected between practices and demographic features or educational level of mothers.
Conclusion: Inappropriate self-medication practices regarding the management of acute diarrhea and ARI and under use of ORS for acute diarrhea were common home practices. There is a great need to increase awareness of mothers about home management through health education programs.

Introduction: Cytokine immunotherapy such as Interleukin-27 (IL-27) has been foreseen as a promising alternative anti-cancer treatment. Thus, this study aimed to investigate whether IL-27 gene therapy regulates crosstalk between breast cancer cells and macrophages in the sense of pro-apoptotic activities. Methods: This study has led to the development of recombinant pcDNA3.4-IL27. The recombinant pcDNA3.4-IL27 was transfected into 4T1 murine mammary carcinoma cells alone and co-culture of 4T1 with M2 macrophages. The successful expression of IL-27 in the cells were determine through the immunofluorescence staining and detection of CD206, M2 macrophages marker. Apoptotic effects of pcDNA3.4-IL27 were assessed through MTT assay, Annexin V flow cytometer analysis, and AO/PI dual staining. Results: Our findings shows that pcDNA3.4-IL27 has the ability to induce apoptosis in both of the cell group and performs better in the co-culture of 4T1 with M2 macrophages compared to 4T1 cells alone. PcDNA3.4-IL27 induced apoptosis through the altered cell morphology and reduction in the number of viable cells. Conclusion: These data demonstrate that pcDNA3.4-IL27 has the ability to induce apoptosis in both 4T1 cell alone and co-cultured 4T1 with M2 macrophages. Thus, could serve as a potential anti cancer candidate against breast cancer.
