Authors: Nguenang L.B. , Kamgnia Emmanuel , Philippe Bernard
Published: January 2021

This article deals with the localization of eigenvalues of a large sparse and not necessarilysymmetric matrix in a domain of the complex plane. It combines two studies carried out earlier.The first work deals with the effect of applying small perturbations on a matrix, and referred to ase -spectrum or pseudospectrum. The second study describes a procedure for counting the numberof eigenvalues of a matrix in a region of the complex plain surrounded by a closed curve. The twomethods are combined in order to share the LU factorization of the resolvent, that intervenes in thetwo methods, so as to reduce the cost. The codes obtained are parallelized.

L’article se consacre à la localisation de valeurs propres pour une grande matrice creuse, apriori non symétrique, dans un domaine du plan complexe. Il combine deux notions déjà étudiées. Lapremière précise l’effet de perturbations sur la matrice par la définition de e -spectre ou pseudospectre.La deuxième consiste à dénombrer les valeurs propres entourées par une courbe a priori donnéedans le plan complexe. A partir de travaux antérieurs, on combine ici les deux approches avec l’objectifde mettre en commun les factorisations LU de la résolvante nécessaire aux deux approches et d’endiminuer le nombre. Les codes obtenus sont parallélisés.
Nonparametric estimation for probability mass function with Disake: an R package for discrete associated kernel estimators
Authors: Wansouwé W.E. , Kokonendji C.C. , Kolyang D.T.
Published: January 2021

Kernel smoothing is one of the most widely used nonparametric data smoothing techniques. We introduce a new R package, Disake, for computing discrete associated kernel estimators for probability mass function. When working with a kernel estimator, two choices must be made: the kernel function and the smoothing parameter. The Disake package focuses on discrete associated kernels and also on cross-validation and local Bayesian techniques to select the appropriate bandwidth. Applications on simulated data and real data show that the binomial kernel is appropriate for small or moderate count data while the empirical estimator or the discrete triangular kernel is indicated for large samples.
Migrations in the Rosenzweig-MacArthur model and the "atto-fox" problem
Authors: Lobry Claude , Sari Tewfik
Published: January 2021

The Rosenzweig-MacArthur model is a system of two ODEs used in population dynamics to modelize the predator-prey relationship. For certain values of the parameters the differential system exhibits a unique stable limit cycle. When the dynamics of the prey is faster than the dynamics of the predator, during oscillations along the limit cycle, the density of preys take so small values that it cannot modelize any actual population. This phenomenon is known as the "atto-fox" problem. In this paper we assume that the populations are living in two patches and are able to migrate from one patch to another. We give conditions for which the migration can prevent the density of prey being too small.

Le modèle de Rosenzweig-MacArthur est un système de deux équations différentielles utilisé en dynamique des populations pour modéliser la relation entre un prédateur et sa proie. Pour certaines valeurs des paramètres le système différentiel possède un cycle limite unique stable. Lorsque la dynamique de la proie est plus rapide que celle du prédateur, durant les oscillations le long du cycle, la densité des proies atteint des valeurs tellement petites qu'elle ne peut modéliser une situation issue du monde réel. Ce phénomène est connu sous le nom du problème "atto-fox". Dans cet article on suppose que les populations sont réparties entre deux patches et qu'elles peuvent migrer de l'un à l'autre. Nous donnons des conditions qui assurent que la migration va empêcher la densité des proies de devenir trop petite.
Analysis of a model describing stage-structured population dynamics using hawk-dove tactics
Authors: Moussaoui Ali , Doanh Nguyen Ngoc , Auger Pierre
Published: January 2021

The purpose of this paper is to investigate the effects of conflicting tactics of resource acquisition on stage structured population dynamics. We present a population subdivided into two distinct stages (immature and mature). We assume that immature individual survival is density dependent. We also assume that mature individuals acquire resources required to survive and reproduce by using two contrasted behavioral tactics (hawk versus dove). Mature individual survival thus is assumed to depend on the average cost of fights while individual fecundity depends on the average gain in the competition to access the resource. Our model includes two parts: a fast part that describes the encounters and fights involves a game dynamic model based upon the replicator equations, and a slow part that describes the long-term effects of conflicting tactics on the population dynamics. The existence of two time scales let us investigate the complete system from a reduced one, which describes the dynamics of the total immature and mature densities at the slow time scale. Our analysis shows that an increase in resource value may decrease total population density, because it promotes individual (i.e. selfish) behavior. Our results may therefore find practical implications in animal conservation or biological control for instance.

Le but de cet article est d'étudier les effets de comportements agressifs dans l'acquisition de ressources sur la dynamique d'une population structurée en deux classes d'âge. Nous considérons une population divisée en deux sous populations distinctes (immatures et adultes matures). Nous supposons que la survie individuelle de la population immature est densité dépendante. Nous supposons également que les individus matures sont en compétition pour acquérir les ressources nécessaires pour leur survie et leur reproduction. Les adultes utilisent deux tactiques comportementales (faucon et colombe). Lors de confrontations entre adultes, la survie d'un individu mature est supposée être affectée par le coût moyen des combats alors que la fécondité dépend du gain moyen obtenu en accédant à la ressource. Notre modèle comprend deux parties : une partie rapide qui décrit les rencontres et les combats basée sur les équations du réplicateur, et une partie lente qui décrit les effets à long terme des tactiques conflictuelles sur la dynamique de la population. L'existence de deux échelles de temps nous permet d'étudier le système complet à partir d'un système réduit, qui décrit la dynamique des densités totales des immatures et des adultes à l'échelle de temps lente. Notre analyse montre que le taux de croissance global de la population dépend de la valeur de la ressource et du coût des combats entre adultes. Nos résultats trouvent des implications pratiques dans la conservation des espèces et le contrôle biologique.
Choice sequence and nonstandard extension of type theory
Authors: Wallet Guy
Published: January 2021

Partant de son travail Mathematics of Infinity (1989), Martin-Löf a développé l'idée d'un lien conceptuel profond entre les notions de suite de choix et d'objet mathématique nonstandard. Précisément, il a défini une extension nonstandard de la théorie des types en ajoutant une série d'axiomes nonstandard conçue comme une sorte de suite de choix. Enfin, dans une communication de 1999, il a présenté les grandes lignes d'une théorie des types nonstandard plus générale et munie d'un fort contenu computationnel. Le présent travail est une tentative de donner un développement complet d'une théorie de ce genre. Cependant, dans le but de garder un fort contrôle sur la théorie résultante et notablement pour éviter quelques problèmes en rapport avec l'égalité définitionnelle, le champ des axiomes nonstandard est moins général que ceux proposés dans sa communication de 1999. L'étude présente est poussée jusqu'à l' introduction d'une notion de proposition externe qui joue le même rôle que les propriétés externes si utiles dans l'analyse nonstandard usuelle. Du fait que ce texte débute par une introduction à la théorie des types de Martin-Löf, il peut intéresser les mathématiciens non familiers avec ce sujet.

Published: January 2021

La quantité des données produites par de nombreux domaines augmente constamment et rend leur traitement de plus en plus difficile à gérer. Parmi ces domaines nous nous intéressons à la biodiversité pour laquelle le GBIF (Global Biodiversity Information Facility) vise à fédérer et partager les données de biodiversité produites par de nombreux fournisseurs à l’échelle mondiale. Aujourd’hui, avec un nombre croissant d’utilisateurs caractérisés par un comportement versatile et une fréquence d’accès aux données très aléatoire, les solutions actuelles n’ont pas été conçues pour s’adapter dynamiquement à ce type de situation. Par ailleurs, avec un nombre croissant de fournisseurs de données et d’utilisateurs qui interrogent sa base, le GBIF est confronté à un problème d’efficacité difficile à résoudre. Nous visons, dans cet article, à résoudre les problèmes de performances du GBIF. Dans cette perspective, nous proposons une approche d’optimisation de requête d’analyse de données de biodiversité qui s’adapte dynamiquement au contexte des environnements répartis à large échelle pour garantir la disponibilité des données. L’implémentation de notre solution et les résultats des expériences sont satisfaisants pour la garantie de performance et du passage à l’échelle.

Authors: Metchebon Takougang Stéphane Aimé , Wethe Joseph
Published: January 2021

This work presents a web-based tool for predicting and evaluating sustainability with a case study in the framework of water delivery service project (WDSP). A decision support model is built, based on Multi-Criteria Decision Analysis (MCDA) and afterward implemented in Java EE platform for predicting and evaluating on-line the sustainability of WDSPs. An additive value function based assignment model is used to sort a WDSP to one of the ordered categories corresponding to various level of sustainability. The model allows to aggregate socioeconomic, technical, technological and environmental aspects in term of their impact on the sustainability. Knowing the sustainability level of a WDSP can serve as a basis for undertaking an intervention.

Ce travail propose un outil de prédiction et d'évaluation en ligne de la durabilité dans le cadre des projets de service d'approvisionnement en eau potable (PSAE). Un modèle de support d'aide à la décision basé sur l'aide multicritère à la décision (AMCD) est construit et ensuite implé-menté sur la plateforme Java EE pour la prédiction et l'évaluation en ligne de la durabilité des PSAE. Un modèle de tri basé sur une fonction de valeur additive est utilisé pour affecter un PSAE à une des catégories ordonnées reflétant différents niveaux de durabilité. Le modèle permet d'agréger les aspects socio-économique, technique, technologique et environnemental en termes d'impact sur la durabilité. Connaître le niveau de durabilité d'un PSAE peut servir de base pour intervenir.
Propriétés d'un circuit graphe minimum
Authors: Nzali Jean-Pierre
Published: January 2021

A graph circuit is a planar graph in which edges are oriented such that any finite face is a circuit. Such graph is said to be minimum if the number of edges oriented in two direction is minimum. In this article we study such graph properties. We prove that each finite face can be characterized by its orientation direction. We also present sum results on the disposition of edges oriented in two directions in a minimum graph circuit.

Un circuit graphe est un graphe planaire topologique dont les arcs sont orientés de telle sorte que chaque face finie soit un circuit. Il est minimum si le nombre d'arcs orientés dans les deux sens est minimum. Dans cet article nous étudions les propriétés d'un tel graphe. Nous montrons que chaque face finie peut être caractérisée par son sens d'orientation. Nous présentons aussi quelques résultats sur la disposition des arcs orientés dans les deux sens sur un circuit graphe minimum.
Self-adaptive structuring for P2P-based large-scale Grid environment
Authors: Gueye Bassirou , Flauzac Olivier , Rabat Cyril , Niang Ibrahima
Published: January 2021

In this paper, we propose an extension and experimental evaluation of our self-adaptive structuring solution in an large-scale P2P Grid environment. The proposed specification, enables both services deployment, location and invocation of while respecting the P2P networks paradigm. Moreover, the specification is generic i.e. not linked to a particular P2P architecture. The increasing size of resources and users in large-scale distributed systems has lead to a scalability problem. To ensure the scalability, we propose to organize the P2P grid nodes in virtual communities. A particular node called ISP (Information System Proxy) acts as service directory within each cluster. On the other hand, resource discovery is one of the essential challenges in large-scale Grid environment. In this sense, we propose to build a spanning tree which will be constituted by the set of formed ISPs in order to allow an efficient service lookup in the system. An experimental validation, through simulation, shows that our approach ensures a high scalability in terms of clusters distribution and communication cost.

Dans cet article, nous proposons une extension et une implémentation de notre solution de structuration auto-adaptative dans un environnement de grilles P2P à large échelle. La spécification que nous avons proposée permet aussi bien le déploiement, la recherche et l’invocation de services tout en respectant le paradigme des réseaux P2P. De plus, elle est générique, c’est-à-dire applicable sur toute architecture pair-à-pair. Pour garantir cette propriété, étant donné que les systèmes distribués à large échelle ont tendance à évoluer en termes de ressources, d’entités et d’utilisateurs, nous proposons de structurer l’environnement de grille pair-à-pair en communautés virtuelles. Au sein de chaque communauté un noeud appelé PSI (Proxys Système d’Information) joue le rôle de registre de services. Afin de permettre une recherche efficace dans le système, un arbre couvrant constitué uniquement des PSI est maintenu. Les résultats de simulations ont montrés que notre solution garantitun passage à l’échelle en termes de dimensionnement du réseau et aussi de coût de recherches.
Arabic topic identification based on empirical studies of topic models
Authors: Naili Marwa , Chaibi Anja , Ghézala Henda
Published: January 2021

This paper focuses on the topic identification for the Arabic language based on topic models. We study the Latent Dirichlet Allocation (LDA) as an unsupervised method for the Arabic topic identification. Thus, a deep study of LDA is carried out at two levels: Stemming process and the choice of LDA hyper-parameters. For the first level, we study the effect of different Arabic stemmers on LDA. For the second level, we focus on LDA hyper-parameters α and β and their impact on the topic identification. This study shows that LDA is an efficient method for Arabic topic identification especially with the right choice of hyper-parameters. Another important result is the high impact of the stemming algorithm on topic identification.

Cet article met l'accent sur l'identification thématique pour la langue arabe basée sur les topic models. Nous étudions l'Allocation de Dirichlet Latente (LDA) comme une méthode non supervisée pour l'identification thématique. Ainsi, une étude approfondie de LDA a été effectuée à deux niveaux: le processus de lemmatisation et le choix des hyper-paramètres. Pour le premier niveau, nous étudions l'effet des différents lemmatiseurs sur LDA. Pour le deuxième niveau, nous nous focalisons sur les hyper-paramètres α et β de LDA et leurs impacts sur l'identification. Cette étude montre que LDA est une méthode efficace pour l'identification thématique Arabe surtout avec le bon choix des hyper-paramètres. Un autre résultat important est l'impact élevé de l'algorithme de lemmatisation sur l'identification thématique.
Stochastic modeling for biotechnologies Anaerobic model AM2b
Authors: Campillo Fabien , Chebbi Mohsen , Toumi Salwa
Published: January 2021

Le modèle AM2b est classiquement représenté par un système d'équations différentielles. Toutefois ce modèle n'est valide qu'en grande population et notre objectif est d'établir plusieurs mo-dèles stochastiques à différentes échelles. À l'échelle microscopique, on propose un modèle sto-chastique de saut pur que l'on peut simuler de fa con exacte. Mais dans la plupart des situations ce genre de simulation n'est pas réaliste, et nous proposons des méthodes de simulation approchées de type poissonnien ou de type diffusif. La méthode de simulation de type diffusif peut être vue comme une discrétisation d'une équation différentielle stochastique. Nous présentons enfin de fa con infor-melle un résultat de type loi des grands nombres/théorème central limite fonctionnelle qui démontre la convergence de ses modèles stochastiques vers le modèles déterministe initial.

The model AM2b is conventionally represented by a system of differential equations. However, this model is valid only in a large population context and our objective is to establish several stochastic models at different scales. At a microscopic scale, we propose a pure jump stochastic model that can be simulated exactly. But in most situations this exact simulation is not feasible, and we propose approximate simulation methods of Poisson type and of diffusive type. The diffusive type simulation method can be seen as a discretization of a stochastic differential equation. Finally, we formally present a result of law of large numbers and of functional central limit theorem which demonstrates the convergence of these stochastic models towards the initial deterministic models.
Dynamics of an HBV infection model with cell-to-cell transmission and CTL immune response
Authors: Besbassi Hajar , Elrhoubari Zineb , Hattaf Khalid , Noura Yousfi
Published: January 2021

In this work, we propose a mathematical model to describe the dynamics of the hepatitis B virus (HBV) infection by taking into account the cure of infected cells, the export of precursor cytotoxic T lympho-cytes (CTL) cells from the thymus and both modes of transmission that are the virus-to-cell infection and the cell-to-cell transmission. The local stability of the disease-free equilibrium and the chronic infection equilibrium is obtained via characteristic equations. Furthermore, the global stability of both equilibria is established by using two techniques, the direct Lyapunov method for the disease-free equilibrium and the geometrical approach for the chronic infection equilibrium.

Dans ce travail, nous proposons un modèle mathématique pour décrire la dynamique du virus d'hépatite B (HBV) en prenant en compte le taux de guérison de cellules infectées, l'exportation de précurseur cytotoxic des lymphocytes T (CTL) des cellules du thymus et les deux modes de transmission qui sont l'infection virus-à-cellule et la transmission cellule-à-cellule.La stabilité locale de l'équilibre libre et l'équilibre d'infection chronique est obtenue via des équations caractéristiques. En outre, la stabilité globale des deux équilibres est établie en utilisant deux techniques, la méthode directe de Lyapunov pour l'équilibre libre et l'approche géométrique pour l'équilibre d'infection chronique.

Published: January 2021

Extending an existing model devoted to the interaction between β-Cell Mass, Insulin, Glucose, Receptor Dynamics and Free Fatty Acids in glucose regulatory system simulation, this paper proposes a mathematical model introducing the effect of growth hormone on the glucose homeostasis alongside the other variables. Stability analysis is carried out and pragmatic explanation of the equilibrium points is emphasized. Finally, simulation illustrated how β-Cell Mass, Insulin, Glucose, Receptor Dynamics, Free Fatty Acids and Growth Hormone may vary with different values of some parameters in the model.

L'analyse de stabilité a été suivie d'explication pratique des points d'équilibre. Enfin, la simulation a illustré comment les cellules beta, l'insuline, le glucose, les recpteurs d'insuline, les acides gras libres et l'hormone de croissance peuvent varier en fonction des différentes valeurs de certains paramètres.
Caste Formation in India.
Authors: D V Sajitha , M P Ajith Kumar
Published: January 2021

The purpose of this study is to look at how caste formation, a structural feature of Indian society and the changes that have taken place in caste formations over time, are used by caste in today’s society. The structure of Indian society is based on the caste system. But the caste system was only a product of the upper caste Brahmins of India. In fact, the upper castes enslaved the lower castes only for economic purposes. For that, they used caste as the first extreme. According to historians, the caste system in India was only part of a division of labor and was never caste-based. Because there is no mention in Manusmriti, Bhagavat Gita, Vedic and Later-Vedic literatues about a caste society that separates man from man on the basis of caste. That is why our social reformers proclaimed that caste evils should be eradicated from the society and they worked hard for it and succeeded to some extent. Thus, Independent India was able to build a casteless society as a result of the work of social reformers. But after independence we were able to see a caste politics. What we see today is that every political party is using caste as a tool for their vote bank during elections to consolidate their power. Therefore, caste politics is one of the major challenges facing India.

Authors:   Breast Division, Department of Surgery, Imam Abdulrahman Bin Faisal University, Dammam, Kingdom of Saudi Arabia, Maha SA Abdel Hadi
Published: January 2021

Based on a follow up update on a previous study performed 2 decades earlier (Ann SM; 2000; 20(2): 135-136). Portraying alarming results on knowledge and attitudes on breast cancer among healthcare professionals from and university hospital. This review aims to explore the current performance of healthcare professionals towards breast cancer awareness in a potentially developed era. Materials and Methods: This Cross-Sectional pilot tested study was conducted at a university hospital targeting all healthcare professionals between June 2017 - December 2017. Designed structured questionnaires were directly distributed to cover demographic data, high-risk factors, knowledge and attitudes towards breast cancer. The target population was 600. Results: The total respondents were 532(88%). Age ranged between 19-59 years with the mean age of 28 years. These where 200(37%) final year medical students, 118(22%) interns, 60(11%) residents 22(4%), specialist 30(5%), 28(5%) consultants, and 74(13%) nurses. High risk group accounted for 120(23%) of all participants. The highest scores were obtained from the younger group of staff, the interns\students (91%, 97%) as compared to the specialist\consultant categories (75%, 82%). Nurses unexpectedly had shown lower scores in knowledge (71%) which may suggest that the practical education in nursing practice supersedes knowledge in special fields. High risk group did not show significant difference in the overall knowledge scores (84%) yet, they scored higher in attitudes towards BCAP (94%). Conclusion: The necessity for (BCAP) cannot be overstated. The impressive and remarkable improvement of breast cancer awareness coupled with the availability and readiness of human resources assist in the planning, implementing and setting guidelines and strategies for breast cancer early detection programs. It can be declared that our community is equipped with knowledgeable medical staff, who can perform adequately run Breast Cancer Awareness Programs.

Published: January 2021

Gestation outside the uterine cavity in which the implantation occurs in any tissue other than the endometrium is referred as ectopic pregnancy. The most places for occurring ectopic pregnancy (97% of cases) are the fallopian tubes including ampulla (55%), isthmus (25%), and fimbria (17%), and in 3% of patient’s ectopic pregnancy occurs in the abdominal cavity, ovary, or cervix. The tubal twin ectopic pregnancy is a rare condition, and the first unilateral tubal twin was reported by De Ott in 1891, and the first live twin tubal ectopic pregnancy was reported in 1944. A live tubal twin ectopic pregnancy is a very rare condition and among >100 reports of tubal twin pregnancies, till now, only 8 cases were live. Early diagnosis and treatment of women with tubal twin ectopic pregnancy is very important and may decrease the risk of tubal rupture. I present three cases of tubal twin ectopic gestation. In the first case, spontaneous unilateral live tubal twin ectopic gestation. The second and third cases spontaneous ruptured twin ectopic gestation. All three cases were successfully managed and there was no history of assisted reproductive techninique fertilization or pelvic inflammatory disease.

The supra-patellar approach represents one approach to intramedullary nailing (IMN) of diaphyseal tibia fractures. Violation of the knee joint utilizing an intra-articular start point represents a risk for septic arthritis of the knee in the post-operative period. Previous retrospective studies of open tibia and femur fractures demonstrated that post-operative knee sepsis is rare, occurs in the chronic phase after injury, and due to extent of soft tissue injury rather than immune compromise. Here, we review current literature on post-operative knee sepsis, and present a case of acute septic arthritis of the knee following supra-patellar nailing of an open tibia fracture in a patient on chronic immune suppression. In this unique case, co-morbid patient factors likely led to this manifestation of a rare complication.

Acute confusional state is a challenging condition especially when present in young patients. I am presenting a challenging case of acute confusion in a young patient which was not diagnosed in a timely manner. A 33-year-old pleasant lady was initially admitted with fits and managed with sodium valproate. There were no past medical problems. No cause was found and she was discharged with outpatient neurologist follow up. One week later she re-admitted with confusion, bizarre behaviour and personality change. Her confusion got worse and her personality was changed to that extent that her family and other ward members including nursing staff felt about demonic possession. This presentation was considered secondary to sodium valproate which was changed to phenytoin. Afterward, she went through extensive investigations including CT head, MRI head and Spine, Lumbar puncture, Septic & autoimmune screen. Her pregnancy test was negative. LP results confirmed leucocytosis and EEG showed diffuse abnormality. MRI head showed encephalitis changes, MRV was normal. CSF culture did not grow any organism. She was treated with 14 days course of IV Aciclovir for? encephalitis which did not help and her condition deteriorated further and she was transferred to ITU. Neurologist subsequent review advised for VGKC, NMDA, GAD & Paraneoplastic antibodies. NMDA receptor antibodies result later came back positive. She had a CT TAP & TV ultrasound which ruled out any ovarian malignancy. She was treated with immunoglobins & IV steroids & her condition improved slightly however later she aspirated during fitting and was intubated and transferred to tertiary hospital where she received plasma exchange and got almost full recovery.

The abuse of benzodiazepines by pregnant women can cause intoxication in the neonate. Benzodiazepines can diffuse readily across the placenta to the fetus because of their high lipid solubility. After the sixth month of pregnancy, the loss of the cytotrophoblasts from the placenta further facilitates the transport of benzodiazepines across the placenta. They may persist for at least a week in pharmacologically active concentrations after administration of high dosages to the mother. We report about a floppy, drowsy and pulmonary impaired newborn delivered in the 36th week of gestation. The mother was a regular user of clorazepate, a long-acting benzodiazepine during pregnancy.

Pendidikan yang berkualitas adalah salah satu faktor yang berkontribusi terhadap pembangunan suatu negara dan merupakan salah satu dari 17 sasaran Sustainable Developmet Goals (SDGs). Matematika adalah salah satu mata pelajaran yang diajarkan di sekolah Indonesia. Berdasarkan data dari Program for International Student Assessment (PISA) pada tahun 2012 menyatakan bahwa kemampuan matematika siswa berusia 15 tahun di Indonesia berada di peringkat 63 dari 64 negara dengan skor rata – rata 375. Hal ini menunjukan bahwa, masih rendahya kualitas pendidikan matematika di Indonesia.Tidak hanya kualitas pendidikan matematika di Indonesia. Kecerdasan emosional peserta didik di Indonesia juga masih rendah. Hal ini dibuktikan dengan maraknya masalah – masalah millenial seperti, seks bebas, narkoba, dan kenakalan remaja lainnya. Contohnya, di daerah Ngajuk, dari data Unit PPA tahun 2018 tercatat ada 55 kasus kenakalan remaja dan tahun 2017 hanya 36 kasus atau naik hampir 50%. Selain itu, berdasarkan data KPAI tawuran pelajar di Indonesia pada tahun 2018 meningkat sekitar 1,1% dibandingkan tahun 2017. Berdasarkan pernyataan di atas, maka diperlukan solusi yang tepat guna meningkatkan kualitas pembelajaran matematika dan karakter peserta didik  di Indonesia. Solusi tersebut adalah religious math character. Religious math character merupakan sebuah strategi membelajarkan matematika dengan menanamkan nilai-nilai agama dalam pembelajarannya. Dalam pelaksanaannya, pembelajaran matematika ini menggunakan model pembelajaran pemaknaan. Bedasarkan hasil kajian pustaka, penggunaan strategi pembelajaran matematika berbasis religious math character ini mampu meningkatkan hasil belajar matematika sekaligus etika moral peserta didik melalui langkah – langkah pembelajaran bermakna. Melalui strategi ini pembelajaran matematika lebih bermakna karena mengaitkan konsep bukan hafalan, sehingga dapat meningkatkan kualitas pembelajaran matematika sekaligus karakter peserta didik di Indonesia.

In Ayurveda, Shalyatantra is one of the eminent branches based on six major methods of management among which Agnikarma is boon for local Vata and Kaphaja Vyadhi. Its effect can be assessed as Sthanik Karma (local action), Saarvadaihik Karma (Action throughout the body) and Vishista Karma (Special actions). Based on amount of Agni needed, the condition and site of disease, Dahanupakarana are used to produce therapeutic burns during Agnikarma Chikitsa. It can be classified according to Dravya used, site, disease, Akritiand Dhatu to be cauterized. Based on the Dagdha (Burn), it is again of four type viz. scorched burn, blistered burn, superficial burn and deep burn. Its indication is in all seasons except in summer and autumn. Indications and contraindications are well expounded in classics with detail information on Purva Karma, Pradhana Karma and Paschat Karma during Agnikarma as it is superior to every other procedure used in Ayurveda Surgery. In modern medicine, there is no use of therapeutical burn i.e., Samyak Dagdha Chikitsa but its use is in other form eg., Cauterization is used for coagulation and tissue destruction. Agnikarma is considered as the best therapy to pacify Kaphanubandha Vata Dosha because Agni possesses Ushna, Tikshna, Sukshma, Aashukari Gunas, which have anti Vataja and anti Kaphaja properties. It is done by red hot Shalaka. It gives quick relief to the patient and hence is termed as best therapy.
