Authors: Zolotonosha Oleh
Published: March 2021

The article explores the scientific approaches to defining decentralization. It is analyzed what decentralization is, what is its purpose. The main possibilities are identified. It is emphasized that the benefits of decentralization are the implementation of differentiated policies, effective mobilization at the local level, namely: increasing interest, building partnerships and social cohesion, gaining experience and creating technical groups at the local level; greater flexibility in decision-making and management; possibility of direct physical control at the local level in addition to documentary control. The necessity and efficiency of decentralization are substantiated, through the implementation of reforms aimed at increasing the efficiency of activities of both central and local authorities, as well as creating favorable conditions for economic development. It has been determined that decentralization must necessarily support the functioning of democracy, the proper technical capacity of local self-government and the development of civil society and public organizations.
Coronavirus (COVID-19) and women in higher education in a South African University : Academic and social implications
Authors:   University of Fort Hare, Banda Chitsamatanga Bellita , Malinga Wayne ,   Lupane State University, Zimbabwe
Published: March 2021

History and present realities have presented a dual diachronic relationship between women in higher education and gender inequality. In quintessence, women are and continue to be faced by gendered disparities and practices by institutions of higher learning, coupled with the overarching demand of academic work vis-à-vis family responsibilities. The advent of the novel coronavirus disease (COVID-19) has presented new and continuing academic and social implications for women in academia. This paper adopted a mixed methods approach. Data collection was done using in-depth interviews and survey questionnaires with a sample of 30 respondents, ranging from different academic positions such as lecturer to professor. The paper observed that women face difficulties in balancing work and family responsibilities. Moreover, the adoption of online learning and other digital platforms during the pandemic has its own shortcomings, given the lack of resources and financial support that affect their historically disadvantaged institutions. This has negatively impacted the academic and administrative work of women in academia. The paper recommended that universities and other stakeholders need a comprehensive approach through capacity-building programmes and mentoring to overcome the obstacles and pave the way for the support of women academics to carry out their duties during and after this difficult COVID-19 crisis.

Authors: Bund Eva
Published: March 2021

Um Formen und Rahmenbedingungen von Innovationsprozessen in der öffentlichen Verwaltung zu identifizieren, werden die Veränderungsprozesse im Bundesamt für Migration und Flüchtlinge (BAMF), die während und als Folge der Flüchtlingskrise vollzogen wurden, analysiert. Dazu konzentriert sich dieser konzeptionelle Beitrag auf drei Spannungsfelder, die auf Basis der Erkenntnisse der Innovationsforschung in Unternehmen zentrale Aushandlungsorte von Veränderungen darstellen und auf das Fallbeispiel BAMF im Krisenkontext übertragen werden: 1) das Wechselspiel zwischen politischem und verwaltungsinternem Druck infolge angestiegener Asylzahlen als treibende Kraft für neuartige Lösungen und die dafür notwendige Ressourcenbereitstellung; 2) die Dialektik von Freiraum und Struktur, die von Führungsebenen gesteuert wird und bei einem ausgewogenen Verhältnis Innovationskultur befördern kann; 3) der Umgang mit bestehenden Strukturen im Modifikationsprozess, da Akzeptanz und Effizienz zur nachhaltigen Implementation von Innovation beitragen. Diese Spannungsfelder können als Analyserahmen dienen, um Behörden hinsichtlich ihrer Innovationsfähigkeit zu verorten und Ansatzpunkte für gezielten Spannungsausgleich oder -aufbau zur Förderung von Verwaltungsinnovationen abzuleiten.

Background: Vitamin D deficiency and altered body composition are common in Alzheimer’s disease (AD). Memantine with vitamin D supplementation can protect cortical axons against amyloid-β exposure and glutamate toxicity. Objective: To study the effects of vitamin D deprivation and subsequent treatment with memantine and vitamin D enrichment on whole-body composition using a mouse model of AD. Methods: Male APPswe/PS1dE9 mice were divided into four groups at 2.5 months of age: the control group (n = 14) was fed a standard diet throughout; the remaining mice were started on a vitamin D-deficient diet at month 6. The vitamin D-deficient group (n = 14) remained on the vitamin D-deficient diet for the rest of the study. Of the remaining two groups, one had memantine (n = 14), while the other had both memantine and 10 IU/g vitamin D (n = 14), added to their diet at month 9. Serum 25(OH)D levels measured at months 6, 9, 12, and 15 confirmed vitamin D levels were lower in mice on vitamin D-deficient diets and higher in the vitamin D-supplemented mice. Micro-computed tomography was performed at month 15 to determine whole-body composition. Results: In mice deprived of vitamin D, memantine increased bone mineral content (8.7% increase, p < 0.01) and absolute skeletal tissue mass (9.3% increase, p < 0.05) and volume (9.2% increase, p < 0.05) relative to controls. This was not observed when memantine treatment was combined with vitamin D enrichment. Conclusion: Combination treatment of vitamin D and memantine had no negative effects on body composition. Future studies should clarify whether vitamin D status impacts the effects of memantine treatment on bone physiology in people with AD.
A fuzzy-based check-and-spray geocast routing protocol for opportunistic networks
Authors: Khalid Khuram , Woungang Isaac , Dhurandher Sanjay K. , Singh Jagdeep , Barolli Leonard
Published: March 2021

Unlike communication networks which are traditionally assumed to be connected, Opportunistic networks (OppNets) are a type of wireless ad hoc networks with no guarantee of end-to-end path for data routing, which is due to node mobility, volatile links, and frequent disconnections. As such, data transmission among the nodes relies on their cooperation and this is realized in a store-and-carry fashion. To this end, several opportunistic routing techniques have been proposed in the literature, some of which using geocasting, a technique that consists of scheduling the message to a specific region toward its destination. This paper proposes a Fuzzy-based Check-and-Spray Geocast (FCSG) routing protocol for OppNets, in which a Check-and-Spray mechanism is used to control the message flooding within the destination cast and a fuzzy controller is used for selecting the suitable relay nodes to carry the message toward the destination, with the aim to improve the delivery ratio. Using simulations, the proposed FCSG protocol is shown to outperform the F-GSAF, GeoEpidemic and EECSG routing protocols in terms of overhead ratio, average latency, and delivery ratio, under varying number of nodes, buffer size, and Time-to-Live.
P2PCF: A collaborative filtering based recommender system for peer to peer social networks
Authors: Badis Lyes , Amad Mourad , Aïssani Djamil , Abbar Sofiane
Published: March 2021

The recent privacy incidents reported in major media about global social networks raised real public concerns about centralized architectures. P2P social networks constitute an interesting paradigm to give back users control over their data and relations. While basic social network functionalities such as commenting, following, sharing, and publishing content are widely available, more advanced features related to information retrieval and recommendation are still challenging. This is due to the absence of a central server that has a complete view of the network. In this paper, we propose a new recommender system called P2PCF. We use collaborative filtering approach to recommend content in P2P social networks. P2PCF enables privacy preserving and tackles the cold start problem for both users and content. Our proposed approach assumes that the rating matrix is distributed within peers, in such a way that each peer only sees interactions made by her friends on her timeline. Recommendations are then computed locally within each peer before they are sent back to the requester. Our evaluations prove the effectiveness of our proposal compared to a centralized scheme in terms of recall and coverage.

Long-distance running is an advantage of Chinese sports, but compared with the world level, there is still a big gap. Therefore, an advanced long-distance running training system is urgently needed to scientifically train our long-distance runners to change this situation. The purpose of this article is to study the long-distance running training system under inertial sensor network. According to the actual situation at home and abroad, a human gait analysis system based on inertial sensors is designed. Gait parameters are transformed into clinical medicine through related algorithms and software platforms. Experimental results show that although the step length calculated by the gait analysis system is different from the actual step length, the error value is small, kept below 3 cm, and the error percentage is less than 2%, which meets the accuracy requirements of gait analysis. This fully proves the feasibility of the zero-speed correction method in gait analysis.

Published: March 2021

Lung cancer is the most common cancer throughout the world and identification of malignant tumors at an early stage is needed for diagnosis and treatment of patient thus avoiding the progression to a later stage. In recent times, deep learning architectures such as CNN have shown promising results in effectively identifying malignant tumors in CT scans. In this paper, we combine the CNN features with texture features such as Haralick and Gray level run length matrix features to gather benefits of high level and spatial features extracted from the lung nodules to improve the accuracy of classification. These features are further classified using SVM classifier instead of softmax classifier in order to reduce the overfitting problem. Our model was validated on LUNA dataset and achieved an accuracy of 93.53%, sensitivity of 86.62%, the specificity of 96.55%, and positive predictive value of 94.02%.

Published: March 2021

Breast cancer is a severe disease for women health, however, with expensive diagnostic cost or obsolete medical technique, many patients are hard to obtain prompt medical treatment. Thus, efficient detection result of breast cancer while lower medical cost may be a promising way to protect women health. Breast cancer detection using all features will take a lot of time and computational resources. Thus, in this paper, we proposed a novel framework with surrogate-assisted firefly algorithm (FA) for breast cancer detection (SFA-BCD). As an advanced evolutionary algorithm (EA), FA is adopted to make feature selection, and the machine learning as classifier identify the breast cancer. Moreover, the surrogate model is utilized to decrease computation cost and expensive computation, which is the approximation function built by offline data to the real object function. The comprehensive experiments have been conducted under several breast cancer dataset derived from UCI. Experimental results verified that the proposed framework with surrogate-assisted FA significantly reduced the computation cost.

Study on center-of-sets type-reduction of interval type-2 fuzzy logic systems with noniterative algorithms
Authors: Chen Yang , Yang Jiaxiu
Published: March 2021

In recent years, interval type-2 fuzzy logic systems (IT2 FLSs) have become a hot topic for the capability of coping with uncertainties. Compared with the centroid type-reduction (TR), investigating the center-of-sets (COS) TR of IT2 FLSs is more favorable for applying IT2 FLSs. Actually, it is still an open question for comparing Karnik-Mendel (KM) types of algorithms and other types of alternative algorithms for COS TR. This paper gives the block of fuzzy reasoning, COS TR, and defuzzification of IT2 FLSs based on Nagar-Bardini (NB), Nie-Tan (NT) and Begian-Melek-Mendel (BMM) noniterative algorithms. Six simulation experiments are used to show the performances of three types of noniterative algorithms. The proposed noniterative algorithms can obtain much higher computational efficiencies compared with the KM algorithms, which give the potential value for designing T2 FLSs.
A novel model for semantic similarity measurement based on wordnet and word embedding
Authors: Zhao Fuqiang , Zhu Zhengyu , Han Ping
Published: March 2021

To measure semantic similarity between words, a novel model DFRVec that encodes multiple semantic information of a word in WordNet into a vector space is presented in this paper. Firstly, three different sub-models are proposed: 1) DefVec: encoding the definitions of a word in WordNet; 2) FormVec: encoding the part-of-speech (POS) of a word in WordNet; 3) RelVec: encoding the relations of a word in WordNet. Then by combining the three sub-models with an existing word embedding, the new model for generating the vector of a word is proposed. Finally, based on DFRVec and the path information in WordNet, a new method DFRVec+Path to measure semantic similarity between words is presented. The experiments on ten benchmark datasets show that DFRVec+Path can outperform many existing methods on semantic similarity measurement.

Published: March 2021

The application and analysis of effective blood supply chain network under natural disaster imposed many critical challenges which addressed through an optimization of multiple objectives functions. In this article, relies on reference point algorithm, a user-preference based enriched swarm optimization algorithm is proposed where, inner reference points were produced depending on the perturbed reference point. For each inner reference point, weakly/ɛ-properly Pareto optimal solution was generated using augmented achievement function. All the generated solutions (points) are presented as potential positions for particles in the particle swarm optimization PSO. The proposed algorithm has been reinforced with a novel chaotic contraction operator to retain the feasibility of the particles. To prove the validity of our algorithm, the obtained results are compared with true Pareto optimal front and three of the most salient evolutionary algorithms using inverted generational distance metric IGD. In addition it was implement to detect the most cost and time efficient blood supply chain to provide the required blood types demand on the blood transfusion center in emergence situation, where, it is required to solve this real life application with predefined supply time and predefined supply cost, which is considered as reference point to get the nearby Pareto optimal solution. By the experimental outcomes, we proved that the proposed algorithm is capable to find the set of Paetro optimal solutions nearby the predefined reference points.
Approach-oriented and avoidance-oriented measures under complex Pythagorean fuzzy information and an area-based model to multiple criteria decision-aiding systems
Authors: Chen Ting-Yu
Published: March 2021

The purpose of this paper is to evolve a novel area-based Pythagorean fuzzy decision model via an approach-oriented measure and an avoidance-oriented measure in support of multiple criteria decision analysis involving intricate uncertainty of Pythagorean fuzziness. Pythagorean membership grades embedded in a Pythagorean fuzzy set is featured by tensible functions of membership, non-membership, indeterminacy, strength, and direction, which delivers flexibility and adaptability in manipulating higher-order uncertainties. However, a well-defined ordered structure is never popular in real-life issues, seldom seen in Pythagorean fuzzy circumstances. Consider that point operators can make a systematic allocation of the indeterminacy composition contained in Pythagorean fuzzy information. This paper exploits the codomains of the point operations (i.e., the quantities that express the extents of point operators) to launch new measurements of approach orientation and avoidance orientation for performance ratings. This paper employs such measurements to develop an area-based performance index and an area-based comprehensive index for conducting a decision analysis. The applications and comparative analyses of the advanced area-based approach to some decision-making problems concerning sustainable recycling partner selection, company investment decisions, stock investment decisions, and working capital financing decisions give support to methodological advantages and practical effectiveness.

The matter of the experimental studies of the effect of coatings and technological methods of manufacturing guide elements of universal prefabricated readjustable tooling on their wear resistance are presented. The coatings investigated were made of VK15 carbide powder, which were applied by detonation spraying, and a titanium nitride-based coating produced by condensation with ion bombardment, as well as the surface hardening of guide elements by diamond burnishing for various steels: 20V, 12KhN3A, 40Kh, 38KhMYuA-B and others.During the process of diamond smoothing the roughness improves by 2 - 3 classes and the very nature of the roughness changes: a surface microrelief is created with rounded peaks and valleys instead of microroughness with sharp peaks and valleys, which are characteristic of surfaces after grinding. In this case the bearing surface of the samples increases essentially, and their running-in is accelerated. According to the results of tests under a load of 50, 75 and 100 kgf, a graph of the dependence of wear on the specific pressure was built and it was found that the wear of samples after burnishing decreases by 25 ... 40% compared to polished and at a load of 20 kgf/cm, respectively, is for steel 20 ... 2.7 and 1.9 μm, for steel 12XN3A – 2.3 and 1.6 μm, for steel 40X – 1.8 and 1.3 μm and for steel 38XMYUA – 1.4 and 0.8 μm.With increasing the load the wear of the ground specimens increases sharply, and for the flattened specimens this process is much slower. Based on the test results, graphs of the wear rate were plotted depending on the test duration, as well as for wear in relation to the number of cycles. According to the test results, it was found that steel 38KhMYuA has less wear, which is associated with its high hardness and insignificant tendency to metal seizure. Based on the research results, it was found that different methods of processing parts (previous) grinding and diamond burnishing have different wear. It has been found that diamond burnishing is a very effective surface hardening process.As a result of the tests carried out, it was found that the best performance in testing for wear resistance obtained for a column with TiN coating, the thickness of which does not exceed 0.1 μm, is 5 - 6 times less than the wear resistance of columns with a hard-alloy coating. For the system of directly changeable dies, a pair is recommended, which includes a guide column with a detonation coating VK15 and a holder (sleeve) with a CIB coating based on TiN, since these coatings showed high performance properties and had practically no wear.

Frente a los problemas ambientales y la actividad minera, es importante analizar la relación entre los problemas sociales y ambientales y de salud y las actividades mineras y sus relaciones directas con el desarrollo, especialmente la económica. El presente trabajo tuvo como objetivo evaluar los cambios socioambientales y de salud resultantes de la implementación de grandes proyectos mineros en Barcarena-PA, contextualizando el desarrollo y sus contradicciones en la Amazonía brasileña. Para ello, se utilizó la investigación bibliográfica, sobre la literatura publicada en libros, artículos científicos y documentales, relacionados con el tema en estudio. Se encontró que Brasil representa uno de los mayores potenciales de recursos minerales en el planeta, con aproximadamente 55 tipos de minerales que se pueden utilizar con fines de exploración económica. Por otro lado, además de contribuir al fortalecimiento de la economía regional y nacional y a la generación de empleos y al aumento de los ingresos de la población local, como es el caso del municipio de Barcarena-PA, esta región ha sufrido impactos socioambientales y de salud consecutivos, debido a las actividades mineras desarrolladas en la región. El entorno de los grandes proyectos mineros están habitados por familias que, desde su implementación tienen su forma de vida, su economía, su salud y su organización sociocultural impactada, como resultado de esta actividad y los sucesivos impactos ambientales que se producen en el sitio. Teniendo en cuenta todo lo que se ha analizado, es posible concluir que, debido a que se trata de un modelo de desarrollo económico acelerado, y a menudo no está debidamente planificado, sin tener en cuenta las peculiaridades de la Amazonía brasileña, termina generando numerosos impactos ambientales y sociales que incluso reflejan directamente graves problemas de salud de la población local. Por lo tanto, es esencial repensar urgentemente esta forma de implementación de proyectos de exploración mineral en la región amazónica, como es el caso de la ciudad de Barcarena, porque todavía pueden producirse grandes desastres socioambientales.

The learning process in the clasroom has been focused on teacher centered learning even though student actually also have the potential to gain knowledge independently. The implementation of learning the Pancasila and Citizenship Education subjects has so far impressed that only teachers have extensive knowledge so that lectures and notes are a way of providing material to students. Meanwhile, to get the desired competence, the learning process must be supported by adequate learning facilities. Answering this problem, teachers as facilitators in achieving student competence are required to creatively manage learning. One way is to find alternative solutions, including by developing Modules for learning. The development of this module aims to encourage students to seek their own knowledge without having to depend on the teacher. The development model chosen is based on the Borg and Gall models. The development process is carried out in five main steps, namely: (1) Conducting analysis, (2) Designing the initial product, (3) Validating and revising, (4) Small-scale field trials, and (5) Large group field trials. Based on the results of field trials, the PPKn subject modules are very well qualified, meaning that the PPKn subject modules are interesting, according to the needs and characteristics of students. Furthermore, with the results of the large group trial which concluded that by using the PPKn subject module, student scores increased, this was indicated by the value that was above the value of the minimum completeness criteria. With the existence of the PPKn subject module for vocational students, in the future students will no longer depend on the material presented by the teacher in class, but are able to obtain their knowledge independently. Furthermore, in the future learning is no longer focused on teachers but is already focused on students. Then for perfection in the future it is better if the trial use of the module is more expanded so that the results can be a reference for teachers to prepare learning teaching materials.

In general, the application of the concept of organizational culture in schools is actually not much different from the application of other organizational culture concepts. Even if there are differences, it may only lie in the type of dominant value it develops and the characteristics of its supporters. This is because the values developed in schools, of course, cannot be separated from the existence of the school itself as an educational organization, which has a role and function to try to develop, preserve and pass on cultural values to students in the school environment.Based on the results of research that has been carried out with data collected both through questionnaires and separate data collection processes (interviews, observation, and documentation), a conclusion is obtained which states that organizational culture and principal leadership together have positive values and affect teacher performance in SMA Negeri 9 Jambi City. This means that teacher performance does not only come from how a teacher is able to carry out the tasks assigned to him, but how the conditions and work environment are so that they are able to give their best.Thus, overall teachers can work well not only supported by the existence of complete learning facilities and facilities, but also several other factors. This is because the high or low performance of a teacher is none other than due to an underlying drive or need to be able to carry out their work load and responsibilities properly.

The use of archimedes screw has shifted its use from pumps to a source of hydropower at low heads as water turbines. Archimedes srew turbine performance is influenced by several parameters including turbine submersion level, turbine tilt angle, pitch ratio, and number of blades. The contour of the lowland Jambi city that is passed by the Batanghari watershed makes the drainage potential can be utilized to become a small-scale hydroelectric power plant using screw turbines, because the contour of Jambi City is low, resulting in small water pressure although the discharge is sometimes large due to the overflow of the Batanghari river, then the choice of turbine with a low head is the solution, in this study, a study was made to calculate the potential drainage flow in the city of Jambi, whether it can be used or not.
