Published: March 2021

The last twenty years the Department of Higher Mathematics and Applied Informatics of Samara State Technical University has been using tests on all chapters of the Mathematics course to control students' knowledge. To understand how objectively a particular test allows a given assessment, it is necessary to examine its quality. Many theories are devoted to this problem. This article will analyze test quality and test tasks based on classical test theory. The study consists of the following stages: compiling a control test; conducting it on a sample of students that meets all the requirements of statistical analysis; processing of this sample and calculation of basic characteristics; analysis of the resulting coefficients, which allows us to conclude whether the test under study can be used as a control of the level of knowledge of students and what changes need to be made in order to improve it. This article analyses some characteristics when examining the quality of the test on the topic "Series" of the course of mathematics, namely, discrimination and validity. To analyze the validity of the test, point biserial correlation coefficients were found - these are correlation coefficients of some task with the student's individual score. After that, the total validity coefficient was calculated. As the calculations showed, the total validity coefficient is 0.53. This is a fairly high indicator, which cannot be said about some point biserial correlation coefficients, namely, for tasks No. 2 and 9. Therefore, these tasks must either be modified or replaced by others. Analysis of the discrimination coefficients of test tasks showed that their values satisfy the requirements of experts.
PHENOMENOLOGICAL PORTRAIT OF SAMARA CHILDHOOD (BASED ON THE PROJECT "ENCYCLOPEDIA OF MODERN CHILDHOOD")
Authors:   Samara branch of the State Autonomous Educational Institution of Higher Education ", Naumova E.A. ,   Moscow City Pedagogical University"
Published: March 2021

The article deals with problems, main directions and methods of studying modern childhood in the humanities. The phenomenon of childhood is characterized as a special sociocultural phenomenon that requires an interdisciplinary methodology for its understanding, as well as implementation of a subjective approach to study rather than a traditional object one. The peculiarity of the research based on the phenomenological approach lies in the formulation and solution of both research and project tasks. Research tasks: fixation, description and interpretation of modern childhood markers based on the material of "Samara childhood"; project tasks: creation and distribution of a methodological product - "Encyclopedia of Modern Childhood" (manuals for adults, created by children), addressed to teachers and parents. The development of the encyclopedia was carried out by the project team of Samara branch MCPU students based on a sample of 2158 Samara schoolchildren. The concept, tools and product of the project "Encyclopedia of Modern Childhood" are characterized. The structure of the empirical content served as the basis for the sections of the manual: "Childhood: associations, thoughts and more", "Growing up, adults, addressing adults", "World of childhood", applications "Incomprehensible words for adults". The interpretive part of the research is represented by a selective content analysis of concepts "childhood", "adult" based on the secondary processing of the results. The analysis of the results reveals the following conclusions: the timeless archetype of child's consciousness maintains the dichotomous opposition of the "world of adults" (boring, problematic) and the "world of children" (carefree, sunny, positive); despite intensification, informatization of the way of life and transformation of the growing environment of a modern child, the perception of childhood as a special, inimitably happy chronotope is inherent in children.

Presenting modern society as a super system, which includes a significant number of subsystems, we distinguish education among them. Because it is education that is designed to respond to emerging social problems, thereby promoting trends that are in demand in society. In relation to today's reality, it is education that will be a kind of bridge to a prosperous future for society. One of the most important elements of the education system is the content of education, due to the fact that it should reflect all possible needs of society. The process of forming the content of education is the most important link in the chain of stages of achieving the goal of training, regardless of the direction of training specialists. In the current situation, educational organizations try to use their best practices in this matter, while the result of this process does not always suit the future employer. Among the reasons for such situations is ignorance of the existence or lack of knowledge of the requirements of regulatory legal documents regulating activities in certain industries. As a result, the formation of training programs without taking into account these features and a decrease in the quality of education. Unfortunately, a similar situation occurs in the training of specialists in the field of industrial safety. Although, it would seem, no one needs to explain the importance of high-quality training of personnel for the operation of hazardous production facilities. First of all, the trouble-free operation of enterprises and, consequently, the state of protection of citizens depends on its competent and prompt actions.

Authors: Larasati Manggiasih Dwiayu
Published: March 2021

Infertility is a global health problem faced by 8 - 10% of couples in the world. It means 50 - 80 million couples have infertility problem. Knowledge about comprehensive and profound reproductive system is main asset for managing infertility. When look at various factors those contribute to women infertility, so the role of endometrium is very important. The optimal endometrial environment for receiving blastocyst is a major factor in the process of implantation and pregnancy. This study attempts to review and compare sources from research article, case report, and reviews from reputable international journals. Research by Germeyer et all (2010) shows that optimal growth and development of endometrium are factors those greatly contributes for successful implantation which is continued to pregnancy. The same thing is revealed by Neykova review (2020) which states the success implantation process is determined by the quality of the embryo, the readiness of the endometrium to accept the result of conception and interaction, and communication of molecular cells. Currently, various studies are being developed for evaluating endometrium condition through genetic improvement, the use of new biomarkers, non-invasive method even sophisticated method such as proteomic technique Endometrial Receptivity Assay (ERA) in order to solve women infertility problem.

Published: March 2021

The
purpose of this study was to segment inbound tourists to Tanzania using
destination image. A self-administered structured questionnaire was
conveniently distributed to inbound tourist to Tanzania in two major
international airports in Tanzania. The questionnaire captured destination
image using a five point Likert type scale while the demographics, sources of
travel information, and travel behavior were captured using dichotomy or
multiple choice questions. A total of 625 dully filled questionnaires were used
for data analysis. A factor-cluster analysis was used in analyzing the data,
with factor analysis serving in reducing the items into few dimensions that
were subsequently subjected to stepwise cluster analysis. A hierarchical
cluster analysis was used to explore the possible numbers of clusters followed
by hierarchical cluster analysis (k-means) that confirmed the appropriate
number of clusters. A three cluster solution was obtained with follow up one
way ANOVA, t-tests, and Chi-square indicating statistical significance differences
between the clusters basing on travel motives and travel behavior. The findings
offer practical implications to destination managers on the use of destination
image in marketing destinations to different tourist segments. This study
explored the possible tourist segments basing on destination image of less
researched African context.

The article presents the results of studies on the epizootic and epidemiological situation in the territory of Yakutia for particularly dangerous invasive diseases-Diphyllobothriosis, Trichinosis, Echinococcosis and Teniarynchosis. The article reflects the results of the authors own research with such components as the infestation of fish, bears, wild and domestic animals and epidemiological surveillance of the disease of the population with these Helminthiasis. It is noted that the obtained data on the dynamics of the morbidity of the population in comparison with the indicators of Russia exceeds several times. Infection of animals and fish with pathogens of dangerous invasive diseases creates conditions for the formation of natural foci, and prevention issues remain relevant due to the high level of morbidity, infestations that transmit through fish, wild and domestic animals predominate.
Analysis of methods determining the value of the vessel’s critical speed when entering the lock chamber minimum width

Published: March 2021

The paper presents an analysis of analytical dependencies to determine the value of the critical speed of the vessel when entering the lock chamber. It is presented the analysis of analytical dependences for determining the value of the critical ship’s speed when entering the lock chamber, obtained by various authors earlier in the course of model and full-scale tests. The main factors affecting the safety of the approach process are noted. It was established that the critical velocity values calculated by various methods give a spread of values. However, some of them do not allow determining the value of the critical speed when the vessel enters the lock at high values of the constraint coefficient. It is indicated that the safe and effective speed of entry into the lock depends on the speed of the stream flowing around the hull of the vessel, which, in turn, is determined by the height of the shear wave in front of the ship’s bow (i.e., the slope of the free surface of the water). These factors lead to the conclusion that further research is necessary

Sustaining Star Formation in the Galactic Star Cluster M 36?
Authors: Panja Alik , Chen Wen Ping , Dutta Somnath , Sun Yan , Gao Yu , Mondal Soumen
Published: March 2021

We present comprehensive characterization of the Galactic open cluster M 36. Some 200 member candidates, with an estimated contamination rate of ∼8%, have been identified on the basis of proper motion and parallax measured by the Gaia DR2. The cluster has a proper motion grouping around (

mas yr−1, and μ

δ
= − 3.35 ± 0.02 mas yr−1), distinctly separated from the field population. Most member candidates have parallax values 0.7–0.9 mas, with a median value of 0.82 ± 0.07 mas (distance ∼1.20 ± 0.13 kpc). The angular diameter of

determined from the radial density profile then corresponds to a linear extent of 9.42 ± 0.14 pc. With an estimated age of ∼15 Myr, M 36 is free of nebulosity. To the southwest of the cluster, we discover a highly obscured (A

V
up to ∼23 mag), compact (∼

) dense cloud, within which three young stellar objects in their infancy (ages ≲0.2 Myr) are identified. The molecular gas, 3.6 pc in extent, contains a total mass of (2–3) × 102
M
⊙, and has a uniform velocity continuity across the cloud, with a velocity range of −20 to −22 km s−1, consistent with the radial velocities of known star members. In addition, the cloud has a derived kinematic distance marginally in agreement with that of the star cluster. If physical association between M 36 and the young stellar population can be unambiguously established, this manifests a convincing example of prolonged star formation activity spanning up to tens of Myr in molecular clouds.
Self-gravitating Equilibria of Non-minimally Coupled Dark Matter Halos
Authors: Gandolfi Giovanni , Lapi Andrea , Liberati Stefano
Published: March 2021

We investigate self-gravitating equilibria of halos constituted by dark matter (DM) non-minimally coupled to gravity. In particular, we consider a theoretically motivated non-minimal coupling that may arise when the averaging/coherence length L associated with the fluid description of the DM collective behavior is comparable to the local curvature scale. In the Newtonian limit, such a non-minimal coupling amounts to a modification of the Poisson equation by a term L
2∇2
ρ proportional to the Laplacian of the DM density ρ itself. We further adopt a general power-law equation of state p ∝ ρ
Γ

relating the DM dynamical pressure p to density ρ and radius r, as expected for phase-space density stratification during the gravitational assembly of halos in a cosmological context. We confirm previous findings that, in the absence of non-minimal coupling, the resulting density ρ(r) features a steep central cusp and an overall shape mirroring the outcomes of N-body simulations in the standard ΛCDM cosmology, as described by the classic Navarro–Frenk–White or Einasto profiles. Most importantly, we find that the non-minimal coupling causes the density distribution to develop an inner core and a shape that closely follows the Burkert profile out to several core scale radii. In fact, we highlight that the resulting mass distributions can fit, with an accuracy comparable to Burkert’s one, the coadded rotation curves of dwarf, DM-dominated galaxies. Finally, we show that non-minimally coupled DM halos are consistent with the observed scaling relation between the core radius r

The Wolf–Rayet + Black Hole Binary NGC 300 X-1: What is the Mass of the Black Hole?
Authors: Binder Breanna A. , Sy Janelle M. , Eracleous Michael , Christodoulou Dimitris M. , Bhattacharya Sayantan , Cappallo Rigel , Laycock Silas , Plucinsky Paul P. , Williams Benjamin F.
Published: March 2021

We present new X-ray and UV observations of the Wolf–Rayet + black hole (BH) binary system NGC 300 X-1 with the Chandra X-ray Observatory and the Hubble Space Telescope Cosmic Origins Spectrograph. When combined with archival X-ray observations, our X-ray and UV observations sample the entire binary orbit, providing clues to the system geometry and interaction between the BH accretion disk and the donor star wind. We measure a binary orbital period of 32.7921 ± 0.0003 hr, in agreement with previous studies, and perform phase-resolved spectroscopy using the X-ray data. The X-ray light curve reveals a deep eclipse, consistent with inclination angles of i = 60°–75°, and a pre-eclipse excess consistent with an accretion stream impacting the disk edge. We further measure radial velocity variations for several prominent far-UV spectral lines, most notably H ii
λ1640 and C iv
λ1550. We find that the He ii emission lines systematically lag the expected Wolf–Rayet star orbital motion by a phase difference of Δϕ ∼ 0.3, while C iv
λ1550 matches the phase of the anticipated radial velocity curve of the Wolf–Rayet donor. We assume the C iv
λ1550 emission line follows a sinusoidal radial velocity curve (semi-amplitude = 250 km s−1) and infer a BH mass of 17 ± 4 M
⊙. Our observations are consistent with the presence of a wind-Roche lobe overflow accretion disk, where an accretion stream forms from gravitationally focused wind material and impacts the edge of the BH accretion disk.
Thermodynamically Governed Interior Models of Uranus and Neptune
Authors: Bailey Elizabeth , Stevenson David J.
Published: March 2021

Interior models of Uranus and Neptune often assume discrete layers, but sharp interfaces are expected only if major constituents are immiscible. Diffuse interfaces could arise if accretion favored a central concentration of the least volatile constituents (also, incidentally, the most dense); compositional gradients arising in such a structure would likely inhibit convection. Currently, two lines of evidence suggest possible hydrogen–water immiscibility in ice giant interiors. The first arises from crude extrapolation of the experimental H2–H2O critical curve to ∼3 GPa. The data are obtained for an impure system containing silicates, though Uranus and Neptune could also be “dirty.” Current ab initio models disagree (Soubiran & Militzer 2015), though hydrogen and water are difficult to model from first-principles quantum mechanics with the necessary precision. The second argument for H2–H2O immiscibility in ice giants, outlined herein, invokes reasoning about the gravitational and magnetic fields. While consensus remains lacking, here we examine the immiscible case. Applying the resulting thermodynamic constraints, we find that Neptune models with envelopes containing a substantial water mole fraction, as much as

relative to hydrogen, can satisfy observations. In contrast, Uranus models appear to require

, potentially suggestive of fully demixed hydrogen and water. Enough gravitational potential energy would be available from gradual hydrogen–water demixing to supply Neptune’s present-day heat flow for roughly 10 solar system lifetimes. Hydrogen–water demixing could slow Neptune’s cooling rate by an order of magnitude; different hydrogen–water demixing states could account for the different heat flows of Uranus and Neptune.
Barcoding pest species in a biodiversity hot-spot: the South African polyphagous broad-nosed weevils (Coleoptera, Curculionidae, Entiminae)
Authors: Hansen Steffan , Addison Pia , Benoit Laure , Haran Julien
Published: March 2021

Polyphagous broad nosed weevils (Curculionidae: Entiminae) constitute a large and taxonomically challenging subfamily that contains economically significant agricultural pests worldwide. South Africa is a hot-spot for biodiversity and several species of indigenous and endemic genera of Entiminae have shifted onto cultivated plants, with some being phytosanitary pests. The sporadic nature of many species, and the presence of pest complexes and cryptic species presents an identification challenge to non-specialists. Furthermore no comprehensive identification tools to identify immature stages that may be found in crops/soil exist. In this paper a curated barcoding database with 70 COI sequences from 41 species (39 Entiminae, 2 Cyclominae) is initiated, to assist with the complexity of identification of species in this group.

Published: March 2021

Little is known about the life history, ecology, and distribution of the genus Allopaa (Dicroglossidae) and far less recent data is available about the larvae of this taxon. Here, we provide data on the larval stage of Allopaa hazarensis (Dubois and Khan, 1979) from northern Pakistan based on the examination of three tadpoles. Specimens were obtained from two sites in Buner, Khyber Pakhtunkhwa province, Pakistan. Morphological and genetic analysis (mtDNA and nDNA) confirmed the identity of the tadpoles as A. hazarensis. Tadpole characterizations were illustrated by detailed imagery. Basic measurements and details on oral apparatus provide relevant taxonomic characteristics to distinguish the tadpoles of this species from other spiny frogs. The illustration and description of the tadpole of A. hazarensis should facilitate the identification of this species in the field.

Ces nouvelles tensions mettent la lumière sur la rivalité historique entre les deux pays, qui remonte à leur indépendance. Des tensions qui ont été exacerbées par le dossier du Sahara et la question des frontières, qui sont fermées depuis 1994. Deux questions qui constituent deux points d’achoppement des relations entre Rabat et Alger. Les récentes tensions interviennent ainsi sur fond d’une rivalité régionale et continentale, poussant les deux pays vers une course aux armements. Des tensions qui bloquent tout espoir de dialogue et de coopération entre les deux pays, qui font face à d’énormes enjeux économiques et sécuritaires.
Conditions sociales des femmes dans la Tunisie contemporaine : entre symbolisme féministe et justice spatiale
Authors: Manaï Bochra
Published: March 2021

Dans l’ensemble des pays musulmans la Tunisie est souvent présentée comme un pays avant-gardiste en matière de droits des femmes, et ce depuis les premières années de la décolonisation. Malgré la visibilité politique des femmes élues sous diverses bannières politiques, ou leur accession à diverses instances de gouvernance, dans les institutions ou les entreprises, on peut se demander si les conditions socio-­économiques des femmes tunisiennes ont changé depuis 2010. Un féminisme symbolique n’a-t-il pas caché l’absence de redistribution sociale ? Dans cet article, nous évoquerons certains enjeux reliés à la place des femmes dans la société, notamment entre les diverses zones du pays où le littoral urbanisé domine économiquement l’arrière-pays.
Retour géopolitique sur la situation postcoloniale et l’histoire coloniale de l’Algérie et du Maroc
Authors: Lacoste Yves , Giblin Béatrice
Published: March 2021

Les rapports actuels entre les pays du Maghreb – Tunisie, Algérie, Maroc – et la France sont la conséquence géopolitique des colonisations et des décolonisations, pluriel qui indique que celles-ci furent spécifiques à chacun de ces trois États. Pourtant, nombre de discours parlent encore de colonisation et de décolonisation au singulier sans se préoccuper plus que ça de leurs différences, sans doute parce que de leur point de vue les ravages de la colonisation et de la décolonisation ont été tels que les différences en deviennent négligeables. Pour certains intellectuels et militants, il est urgent de décoloniser les mentalités françaises, le passif colonial continuant à structurer les représentations des Français blancs qui voient toujours les minorités noires et arabes comme des « indigènes » et non comme des Français à part entière. Sans toutefois s’interroger sur ce paradoxe que représente leur installation volontaire dans l’ancien pays colonisateur. C’est pourquoi, il nous est apparu utile de revenir sur les histoires coloniales de l’Algérie et du Maroc dans un entretien avec Yves Lacoste pour mieux comprendre la complexité des situations postcoloniales française, algérienne et marocaine.
Multi-aircraft cooperative path planning for maneuvering target detection
Authors: Wang Yongkun , He Fengshou , Deng Xiaobo
Published: March 2021

Multi-aircraft cooperative path planning is a key problem in modern and future air combat scenario. In this paper, this problem is studied in aspect of airborne radar detection to maintain a continuous tracking of a manoeuvring air target. Firstly, the objective function is established in combination with multiple constraints considered, including Doppler blind zone constraint, radar viewing aspect constraint, baseline constraint, and so on. Then, the above optimal control problem is transformed into a nonlinear programming problem with a series of algebraic constraints by hp-adaptive Gauss pseudospectral method (HPAGPM). And it is solved by GPOPS software package based on MATLAB. Simulation results show that the optimized cooperative paths can be got to achieve continuous tracking of maneuvering air target by HPAGPM.
Multi-objective optimization for a combined location-routing-inventory system considering carbon-capped differences
Authors: Ji Shoufeng , Tang Jinhuan , Sun Minghe , Luo Rongjuan
Published: March 2021

A combined location-routing-inventory system (CLRIS) in a three-echelon supply chain network is studied with environmental considerations. Specifically, a bi-objective mixed integer programming model is formulated for the CLRIS to deal with the trade-offs between the total cost and the carbon-capped difference (CCD). A multi-objective particle swarm optimization (MOPSO) heuristic solution procedure is developed and implemented to solve the bi-objective mixed integer programming problem. The bi-objective mixed integer programming model and the MOPSO heuristic procedure are applied to a real-life problem as an illustrative example. The approximate nondominated frontier formed by solutions not dominated by others can be used for the decision makers to make trade-offs between the total cost and the CCD. Sensitivity analyses are conducted, and the relationship among the carbon cap, CCD, the total cost and the carbon prices are examined, and relevant managerial insights are provided. Comparisons with other existing algorithms show that the MSPSO heuristic procedure has very good performance.

Among the other cancer types, the brain tumor is one the leading cause of cancer across globe. If the tumor is properly identified at an earlier stage, then the chances of the survival can be increased. To categorize the brain tumor there are several factors including texture, type and location of brain tumor. We proposed a novel reconstruction independent component analysis (RICA) feature extraction method to detect multi-class brain tumor types (pituitary, meningioma, and glioma). We then employed the robust machine learning techniques as support vector machine (SVM) with quadratic and linear kernels and linear discriminant analysis (LDA). For training and testing of the data validation, a 10-fold cross validation was employed. For the multi-class classification, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy and AUC were, respectively, 97.78%, 100%, 100%, 99.07, 99.34% and 0.9892 to detect pituitary using SVM Cubic followed by meningioma with accuracy (96.96%0, AUC (0.9348) and glioma with accuracy (95.88%), AUC (0.9635). The findings indicates that RICA feature based proposed methodology has more potential to detect the multiclass brain tumor types for improving diagnostic efficiency and can further improve the prediction accuracy to achieve the clinical outcomes.
Brexit and war rhetoric : an electoral strategy ?
Authors: Leggett Matthew
Published: March 2021

The English language is replete with bellicose expressions and references to different battles and wars involving British armed forces, in particular World War Two. Many such terms have entered the everyday lexicon of most Eurosceptics and Brexiteers alike. They had already become common currency in anti-European rhetoric since the 1990s, but have reached a greater level of intensity in the last four years since the Brexit referendum, when these groups or individuals discuss or denounce the EU or Brussels. Such emotionally charged words as ‘traitor’, ‘treason’, ‘collusion’, ‘collaboration’, ‘Nazi’ or ‘Gestapo’ alongside terms like ‘the Dunkirk spirit’, hark back to the 1940s, a period of great national pride among many Britons as the country stood fast, resisted and defeated the Nazi threat. Many Brexiteers perceive Brussels as the new Berlin and the European Commission the new Reichstag. These were both fought against in June 2016 and are still demonised in the same way as negotiations over UK/EU relations continue. Using verbatim records of debate from Hansard, references from various books and newspaper articles, this chapter will attempt to study the various military forms of language used in the debate over Britain’s place in the European Union and its withdrawal from it. It will culminate with one very heated exchange that took place on the floor of the House of Commons in late September 2019, when the repeated bellicose language of the Prime Minister, Boris Johnson, and several of his colleagues, were challenged by various members of the opposition parties, and even pro-remain Conservative MPs, in the House. Finally I shall consider whether this choice of words was not part of a greater electoral strategy on the part of Boris Johnson.
Trump’s populist contentment with Brexit
Authors: Smorag Pascale
Published: March 2021

The campaign for Brexit, then its adoption, has been under scrutiny by a pleased-as-punch Donald Trump eager to witness the dawn of a new day for US-UK trade agreements. Promising better economic deals for both countries, Brexit also signified that the UK had finally succeeded in disposing of the European yoke and could now exercise her regained freedom. The nationalist ingredient in supporting Brexit has been fueled by “politics of anger”, which resonate with Trump’s populist rhetoric based on accusations against corrupt elites, citizens’ enemies and conspirators, open borders, multilateral agreements, and die-hard world finance. The resonance between the two nations is even stronger when paralleled with the personalities of both leaders who share in demagogy, bigotry, performance skills, impulsivity, and narcissism. These resemblances become instrumental for D. Trump in implementing his policies, especially when driven, like Boris Johnson, by the urgency of bringing jobs and past glories back. This angry patriotism, as well as the rejection of international institutions and the establishment presented as the villains responsible for Britain’s and America’s dysfunction are very disturbing to Trump’s detractors. This paper examines American perceptions of Brexit, supporters and detractors alike, as well as studying the ambiguous and ambivalent, yet inevitable and indispensable relationship between the UK and the USA.
Zines
Authors: Smith Christopher
Published: March 2021

By using zines as a touchstone, this chapter introduces the idea of multidisciplinary writing through that medium. It focuses on the many elements that embody a zine, from the layout and design to the addition of artwork, publication details, and—of course—the content itself. In regards to the content, this chapter explores the diverse culture of zinesters, illustrating the wide variety of content and, even more, how that content often draws from multiple disciplines to achieve its purpose. By noting both real-life zine examples and assignments, this chapter melds the worlds of multidisciplinary writing and zines, introducing both to the readers.

Published: March 2021

This chapter discusses the implementation of a literacy achievement program, the Carnegie Kids Club (CKC), developed by Carnegie Writers, Inc. (CW), a nonprofit organization that focuses on writing and literacy education. CKC is a community-based program designed to assist children with the improvement of literacy skills as they relate to reading, writing, and creativity. With this, the program seeks to approach literacy development skills based on addressing critical thinking skills, as these are soft skills that promote the development of hard skills. The chapter includes relevant literature about literacy development, programs, instruction, and evaluation. Lastly, it provides the CKC current structural model, assessment, and future research.
