ABSTRAKAngka kriminalitas yang meningkat menjadi salah satu permasalahan pembangunan di kota Balikpapan. Tindakan kriminalitas seperti pencurian, penculikan anak, tindakan asusila terhadap perempuan dan sebagainya sangat meresahkan warga. Tidak terkecuali untuk warga perumahan Griya Wiyata Asri (GWA) III, RT 19, Kelurahan Karang Joang, Balikpapan. Sejauh ini, pelaksanaan Siskamling terbukti efektif dalam meminimalisir terjadinya tindak kejahatan di perumahan GWA III, terutama pada malam hari. Namun, permasalahan terjadi pada siang hari karena mayoritas warga perumahan masuk dalam kategori produktif, bekerja sehingga berada di luar perumahan, bahkan ada yang di luar kota. Suasana perumahan sangat sepi, sehingga meninggalkan celah tindakan kriminalitas bisa terjadi pada siang hari. Oleh karena itu, dibutuhkan upaya penanggulan atau pencegahan tindak kriminalitas. Untuk membantu upaya pencegahan tindak kriminalitas, dirakitlah sebuah Unmanned Aerial Vehicle (UAV). UAV ini digunakan untuk memantau kondisi di perumahan GWA III. Metode evaluasi dari pengabdian masyarakat tahap awal ini adalah sebatas melalui  observasi hasil pemantauan udara. Dari hasil foto, kejernihan foto dan kondisi perumahan yang dapat diobservasi secara jelas per bingkai foto udara, maka UAV ini berpotensi untuk digunakan sebagai penunjang siskamling dengan permasalahan kurangnya sumber daya manusia pada siang hari di perumahan GWA III ini.     Kata kunci: UAV; siskamling; keamanan. ABSTRACTBalikpapan, a city of oil.

Authors: Belyaeva Natalia V. , Aristova Maria A. , Kritarova Zhanna N.
Published: November 2020

The article explains the purpose of creating an exemplary program of the subject “Native literature (Russian)” connected with the execution of the Federal Law on Education, supporting the main aim of the core course in literature – the development of a competent reader, as well as reinforcing the cultivating function of school literary education and preserving the Russian language, literature and culture against the background of Russian multi-ethnic and multicultural society. The following objectives of the new subject acquire particular significance: perceiving literature as one of the main cultural values of the nation (which reflects its national character, history, worldview); ensuring cultural self-identification, becoming aware of the communicative and aesthetic power of the mother tongue based on the study of outstanding literary creations of the Russian culture, the culture of one’s ethnic group, world culture. The methodological background to the exemplary program rests upon the idea of an ideological nature and educational potential of the Russian literature. In creating the didactic model in question, the authors of the program used theoretical and practical research methods, as well as the cognitive and system- and activity-based approaches. The results of the research were as follows: validation of the legal and regulatory framework of the new subject and the primary goals of its study, elaboration of the principles – which are based on the system of value codes shared by the whole nation’s cultural tradition – according to which the contents and structure of the course are selected. The article demonstrates what distinguishes “Native literature (Russian)” from the school subject “Literature”, how each of the three content branches of the program contributes to the development of subject knowledge and skills from grade to grade, why this or that recommended literary work is included in the topic-issue units, and which forms of the final subject assessment are most preferable. The exemplary program of the subject contributes to solving the issue of national and cultural identity and understanding what role the Russian literature plays in becoming aware of the national traits of the Russian culture. It also fosters the comprehension of cultural concepts that are crucial for the Russian national consciousness and the development of one’s ability to transform his/her reflections on works of native literature into personal convictions and positive values.
“To love nature means to love the Motherland...” (the poem “Sorokoust” at the lessons of studying the work of S.A. Yesenin’s in the 11th grade)
Authors: Belousova Elena I.
Published: November 2020

The article is devoted to the organization of work on S.A. Yesenin’s poem “Sorokoust” in the context of studying the work of S.A. Yesenin’s in the 11th grade. In the introduction to the article, its purpose is outlined, which the author defines as a justification for the choice of methodological tools for understanding and mastering the classical poetic text included in the school literary education program by high school students. A brief digression into the history of the development, justification, and classification of methods of interaction between teachers and students in literature classes confirms the relevance of the problem in terms of the variety of combinations and patterns not only at the level of methods, but also within the method itself, taking into account the introduction of learning technologies and the development of a modern digital educational environment. Based on the analysis of literary and methodological approaches to the study of S.A. Yesenin’s creativity at school, the author shows the effectiveness of combining various methods and their elements in the study of the poet’s biography (teacher’s recitation, lecture elements, students’ reports with the involvement of media sources and media resources) at the stages of reading and analyzing the poem “Sorokoust” (working with sources, comparing the poem with the life’s primary basis, reading a poem with the involvement of various types of commentary, preparing an expressive reading of the poem by students), at the final classes on the topic (questions and tasks of a problematic, research nature, creative tasks, conducting independent educational research, attracting various types of art). Based on the proposed approach, the article actualizes the direction of the work in which the diversity of methods used is determined by the ideological and artistic creativity of the writer, the poet’s worldview, the atmosphere of the era, becomes a way of understanding the poet’s personality and artistic method by the learners, to find new meanings. The article concerns the choice of methods with the most pronounced focus on the emotional effectiveness of a poetic work on high school students, contributing to the development of the artistic taste and improving the reading and general culture.

Published: November 2020

The generalized statement of theoretical principles of information support of R&D on forecasting and development of oil and gas fields of various geological and genetic types corresponding to modern challenges of objective factors of growth of technical complexity and geological prospecting, exploration and operational works cost is presented.

The main working tool is a targeted multi-scale information modeling of promising geological objects, based on the general theoretical scheme of forecast-paleoreconstructive retrospective-static model with the introduction of the concept of formation-material system of oil and gas accumulation, which includes three cognitive-functional components: initial source, transportation and objects of hydrocarbons localization.

This methodological apparatus provides solutions to the main forecasting and diagnostic tasks: development of localization criteria, forecasting of traps and assessment of the potential of their hydrocarbons realization. The proposed apparatus is multi-scale, i.e. one that provides forecasting at the zonal (group of deposits), local (deposits) and sublocal (productive beds) levels.

Prospects for further development of the direction are to develop a modern holistic theory of geoinformatic modeling and its subject methodological and methodological section – frame organization of the geological environment of oil and gas specialization in order to innovatively increase the efficiency of hydrocarbon field development. The examples of updated target information modeling of promising geological objects, basing upon methodological approach of infogeology with introducing of geological environment frame organization principles are demonstrated. As an object of modeling the regional formational complex of Tournaisian-Visean oil-gas horizon of the Dniprovsko-Donetska depression is considered. The solution of tasks, connected with this problem, comprises: the revision of initial data for innovative presenting of geoinformation modeling; defining of selected geological objects frame organization (structure); development of different scale promising geological objects frames and their transformation into geoinformatic format; preparing of recommendations for promising geological objects of different scales (zonal, local, sublocal) basing upon pertinent geoinformatic models. The expected result of this methodology introducing is to obtain innovative technology of information supervision for R&D aimed at efficient development of oil and gas fields.
Post-mining of the Ukraine’s mining regions as a new direction for the environmentally safe use of mineral resources
Authors: Rudko H. I. , Yakovlev Ye. O.
Published: November 2020

The growth of market requirements for socio-economic and environmental parameters of mineral resources in most developed (“old”) mining areas (MA) of Ukraine has led to the closure of mines and quarries, including by the method of “wet conservation” (autorehabilitation uncontrolled flooding). This process is most actively developing in the MA of the Donbas, including in areas affected by armed conflict.

In most developed EU countries, the decommissioning of coal mines (Ruhr, Lorraine, Wales), which have large depths (up to 1,0–1,5 km) and area (thousand sq. km) of minefields, is a research and production complex of post-mining (PM), which is based on scientific and technical measures to prevent dangerous changes in the geological environment (GE) - subsidence of the earth’s surface, flooding of lands, release of explosive and toxic gases, limiting the leakage of polluted water. In addition, the PM provides for the transformation of part of the mine workings into a hydraulic filtration system of mine water retention at a depth of 250–350 m in order to prevent the flow of pollutants into freshwater horizons and river network, preservation of regional aquicludes, degassing of mining space. In general, the set of PM measures is aimed at maintaining the balance and protective potential of the GE as a mineral and landscape base of the biosphere.

In this regard, the article compares the protective potential of the GE of the Chornobyl accident zone and the Donbas region, as well as performs an expert assessment of the environmental protection potential of the PM in the leading MA of Ukraine.

It is shown that a new model of mineral resourses use, structure of geological exploration works, scientific substantiation of maximum allowable changes of GE at closing of “old” and formation of new MA, improvement of environmental monitoring based on GIS technologies and remote sensing of the Earth are needed.
Deutsche Betriebsräte in multinationalen Unternehmen: Befunde zur Artikulation von Interessen in Mehrebenensystemen
Authors: Haipeter Thomas , Rosenbohm Sophie
Published: November 2020

Die deutschen Arbeitsbeziehungen zeichnen sich – gerade auch im internationalen Vergleich – durch ein komplexes Geflecht unterschiedlicher Akteure, Ebenen und Institutionen der kollektiven Interessenvertretung aus. Im Zentrum des Beitrags steht ein besonders komplexes Mehrebensystem: die Koordinierung und Integration von Arbeitnehmerinteressen in multinationalen Unternehmen. Basierend auf zehn Fallstudien wird analysiert, wie aus Sicht deutscher Betriebsräte Interessen integriert und koordiniert werden, welche Rolle hierbei Gesamt- und Konzernbetriebsräte sowie die Mitbestimmung im Aufsichtsrat spielen und welche Bedeutung deutsche Betriebsräte der transnationalen Interessenvertretungsebene zumessen. Die Analyse fördert drei zentrale Befunde zu Tage. Erstens bilden in den untersuchten Unternehmen jeweils der GBR oder auch der KBR das Zentrum der Interessenintegration und -koordination. In diesen Gremien werden Interessen gebündelt, um sie dann gegenüber der Unternehmensseite zur Geltung bringen zu können, und sie sind Sammelstellen der Information und der Interessenvertretungsmacht. Zweitens spielen die deutschen Interessenvertretungen eine zentrale Rolle für die transnationale Interessenvertretung, entweder als starke und einflussreiche Interessenvertretungen am Hauptsitz oder als wichtige Akteure in den transnationalen Gremien. Drittens sind zentrale Unterschiede zwischen den Betriebsräten in Unternehmen mit Sitz in Deutschland und den Betriebsräten in deutschen Tochtergesellschaften ausländischer Unternehmen zu beobachten.
Was beeinflusst die Weiterbildungsbereitschaft von Beschäftigten? Befunde aus einer Vignettenstudie
Authors: Osiander Christopher , Stephan Gesine
Published: November 2020

Berufliche Weiterbildung kann Beschäftigte dabei unterstützen, sich den wandelnden Anforderungen des Arbeitsmarktes anzupassen. Dies erfordert nicht nur, dass passende Weiterbildungsangebote zu Verfügung stehen und Betriebe ihren Beschäftigten eine Teilnahme ermöglichen. Beschäftigte müssen darüber hinaus auch bereit sein, sich weiterzubilden. Diese Studie untersucht mithilfe eines faktoriellen Surveys, wie die Ausgestaltungsmerkmale beruflicher Weiterbildung die selbsteingeschätzte Teilnahmewahrscheinlichkeit von Beschäftigten beeinflussen. Im Ergebnis schätzen Beschäftigte ihre Teilnahme als wahrscheinlicher ein, wenn die Weiterbildung vollständig auf die Arbeitszeit angerechnet wird, wenn der Arbeitgeber die Weiterbildungskosten komplett übernimmt, und wenn sich die Weiterbildung für den Arbeitnehmer oder die Arbeitnehmerin finanziell auszahlt. Längere Pendelzeiten zur Weiterbildungsstätte wirken sich hingegen negativ auf die wahrgenommene Teilnahmewahrscheinlichkeit aus. Insgesamt geben die Ergebnisse Hinweise darauf, wie sich die Weiterbildungsbereitschaft von Beschäftigten positiv oder negativ beeinflussen lässt. Besonders wichtig ist dies für Personengruppen, die bisher vergleichsweise wenig an beruflicher Weiterbildung teilnehmen.
Introduction to special issue algorithmic transparency in government: Towards a multi-level perspective
Authors: Giest Sarah , Grimmelikhuijsen Stephan
Published: November 2020

The editorial sets the stage for the special issue on algorithmic transparency in government. The papers in the issue bring together transparency challenges experienced across different levels of government, including macro-, meso-, and micro-levels. This highlights that transparency issues transcend different levels of government – from European regulation to individual public bureaucrats. With a special focus on these links, the editorial sketches a future research agenda for transparency-related challenges. Highlighting these linkages is a first step towards seeing the bigger picture of why transparency mechanisms are put in place in some scenarios and not in others. Finally, this introduction present an agenda for future research, which opens the door to comparative analyses for future research and new insights for policymakers.

Published: November 2020

Background: The cerebrospinal fluid (CSF) biomarkers amyloid-β 1–42 (Aβ42), total and phosphorylated tau (t-tau, p-tau) are increasingly used to assist in the clinical diagnosis of Alzheimer’s disease (AD). However, CSF biomarker levels can be affected by confounding factors. Objective: To investigate the association of white matter hyperintensities (WMHs) present in the brain with AD CSF biomarker levels. Methods: We included CSF biomarker and magnetic resonance imaging (MRI) data of 172 subjects (52 controls, 72 mild cognitive impairment (MCI), and 48 AD patients) from 9 European Memory Clinics. A computer aided detection system for standardized automated segmentation of WMHs was used on MRI scans to determine WMH volumes. Association of WMH volume with AD CSF biomarkers was determined using linear regression analysis. Results: A small, negative association of CSF Aβ42, but not p-tau and t-tau, levels with WMH volume was observed in the AD (r2 = 0.084, p = 0.046), but not the MCI and control groups, which was slightly increased when including the distance of WMHs to the ventricles in the analysis (r2 = 0.105, p = 0.025). Three global patterns of WMH distribution, either with 1) a low, 2) a peak close to the ventricles, or 3) a high, broadly-distributed WMH volume could be observed in brains of subjects in each diagnostic group. Conclusion: Despite an association of WMH volume with CSF Aβ42 levels in AD patients, the occurrence of WMHs is not accompanied by excess release of cellular proteins in the CSF, suggesting that WMHs are no major confounder for AD CSF biomarker assessment.

Objective: To evaluate: 1) possible retinal thickness changes following BACE inhibition; and 2) possible association between retinal thickness and brain atrophy. Methods: Retinal thickness was measured using spectral-domain optical coherence tomography in a 78-week randomized placebo-controlled trial of verubecestat in 1,785 patients with mild-to-moderate AD. Changes from baseline in retinal pigment epithelium, macular grid retinal nerve fiber layer, central subfield retinal thickness, and macular grid volume were evaluated for verubecestat versus placebo. Correlation analyses were performed to investigate the potential association between macular grid retinal nerve fiber layer and central subfield retinal thickness with brain volumetric magnetic resonance imaging (vMRI) data at baseline, as well as correlations for changes from baseline at Week 78 in patients receiving placebo. Results: Verubecestat did not significantly alter retinal thickness during the trial compared with placebo. At baseline, mean macular grid retinal nerve fiber layer and central subfield retinal thickness were weakly but significantly correlated (Pearson’s r values≤0.23, p-values < 0.01) with vMRI of several brain regions including whole brain, hippocampus, and thalamus. At Week 78, correlations between retinal thickness and brain vMRI changes from baseline in the placebo group were small and mostly not statistically significant. Conclusion: BACE inhibition by verubecestat was not associated with adverse effects on retinal thickness in patients with mild-to-moderate AD. Correlations between retinal thickness and brain volume were observed at baseline.

Robust multimodal biometric authentication algorithms using fingerprint, iris and voice features fusion
Authors: El_Tokhy Mohamed S.
Published: November 2020

Development of a robust triple multimodal biometric approach for human authentication using fingerprint, iris and voice biometric is the main objective of this manuscript. Accordingly, three essential algorithms for biometric authentication are presented. The extracted features from these multimodals are combined via feature fusion center (FFC) and feature scores. These features are trained through artificial neural network (ANN) and support vector machine (SVM) classifiers. The first algorithm depends on boundary energy method (BEM) extracted features from fingerprint, normalized combinational features from iris and dimensionality reduction methods (DRM) from voice using sum/average FFC. The second proposed algorithm uses extracted features from zoning method of fingerprint, SIFT of iris and higher order statistics (HOS) of voice signals. The third proposed algorithm consists of extracted features from zoning method for fingerprint, SIFT from iris and DRM from voice signals. Classification accuracy of implemented algorithms is estimated. Comparison between proposed algorithms is introduced in terms of equal error rate (EER) and ROC curves. The experimental results confirm superiority of second proposed algorithm which achieves a classification rate of 100% using SVM classifier and sum FFC. From computational point of view, the first algorithm consumes the lowest time using SVM classifier. On other hand, the lowest EER is achieved by first proposed algorithm for extracted features from Karhunen-Loeve transform (KLT) method of DRM. Additionally, the lowest ROC curves are accomplished respectively for extracted features from multidimensional scaling (MDS), generated ARMA synthesis and Isomap features. Their accuracy is improved with SVM. Also, the sum FFC introduces efficient results compared to average FFC. These algorithms have the advantages of robustness and the strength of selecting unimodal, double and triple biometric authentication. The obtained results accomplish a remarkable accuracy for authentication and security within multi practical applications.
The induced basis axioms for a closed G-V fuzzy matroid
Authors: Wu Deyin , Li Yonghong
Published: November 2020

In this paper, we research a class of axioms in closed G-V fuzzy matroids. The main research method is to transform fuzzy matroids into matroids. First, we study many properties of the basis family of induced matroids, and define a new mapping which can reflect the relationship between bases of induced matroids of a G-V fuzzy matroid. Second, we discuss the new mapping, and reveal the relationship and properties among the fundamental sequence, the induced basis family and the new mapping of a G-V fuzzy matroid. From these relationships and properties, we extract four key attributes: normativity property, inclusion property, exchange property, and right surjection. Finally, we propose and prove “the induced basis axioms for a closed G-V fuzzy matroid” by these key attributes. With the help of these axioms, a closed G-V fuzzy matroid can be uniquely determined by a finite number sequence, a subset family and a mapping on this subset family when they satisfy above four attributes, and vice versa.

Authors: Bai Luyi , Li Nan , Bai Huilei
Published: November 2020

With the growing importance of the fuzzy spatiotemporal data in information application, there is an increasing need for researching on the integration method of multi-source heterogeneous fuzzy spatiotemporal data. In this paper, we first propose a fuzzy spatiotemporal RDF graph model based on RDF (Resource Description Framework) that proposed by the World Wide Web Consortium (W3C) to represent data in triples (subject, predicate, object). Secondly, we analyze and classify the related heterogeneous problems of multi-source heterogeneous fuzzy spatiotemporal data, and use the fuzzy spatiotemporal RDF graph model to define the corresponding rules to solve these heterogeneous problems. In addition, based on the characteristics of RDF triples, we analyze the heterogeneous problem of multi-source heterogeneous fuzzy spatiotemporal data integration in RDF triples, and provide the integration methods FRDFG in this paper. Finally, we report our experiments results to validate our approach and show its significant superiority.

Images of green infrastructure (gardens, green corridor, green roofs and grasslands) large area can be captured and processed to provide spatial and temporal variation in colours of plant leaves. This may indicate average variation in plant growth over large urban landscape (community gardens, green corridor etc). Towards this direction, this short technical note explores development of a simple automated machine learning program that can accurately segregate colors from plant leaves. In this newly developed program, a machine learning algorithm has been modified and adapted to give the proportion of different colors present in a leaf. Python script is developed for an image processing. For validation, experiments are conducted in green house to grow Axonopus compressus. Script first extracts different RGB (Red Green and Blue) colors present in the leaf using the K-means clustering algorithm. Appropriate centroids required for the clusters of leaf colors are formed by the K-means algorithm. The new program provides saves computation time and gives output in form of different colors proportion as a CSV (Comma-Separated Values) file. This study is the first step towards the demonstration of using automated programs for the segregation of colors from the leaf in order to access the growth of the plant in an urban landscape.

The emerging technologies with IoT (Internet of Things) systems are elevated as a prototype and combination of the smart connectivity ecosystem. These ecosystems are appropriately connected in a smart healthcare system which are generating finest monitoring activities among the patients, well-organized diagnosis process, intensive support and care against the traditional healthcare operations. But facilitating these highly technological adaptations, the preserving personal information of the patients are on the risk with data leakage and privacy theft in the current revolution. Concerning secure protection and privacy theft of the patient’s information. We emphasized this paper on secure monitoring with the help of intelligently recorded summary’s keyframe extraction and applied two rounds lightweight cosine-transform encryption. This article includes firstly, a regimented process of keyframe extraction which is employed to retrieve meaningful frames of image through visual sensor with sending alert (quick notice) to authority. Secondly, employed two rounds of lightweight cosine-transform encryption operation of agreed (detected) keyframes to endure security and safety for the further any kinds of attacks from the adversary. The combined methodology corroborates highly usefulness with engendering appropriate results, little execution of encryption time (0.2277-0.2607), information entropy (7.9996), correlation coefficient (0.0010), robustness (NPCR 99.6383, UACI 33.3516), uniform histogram deviation (R 0.0359, G 0.0492, B 0.0582) and other well adopted secure ideology than any other keyframe or image encryption approaches. Furthermore, this incorporating method can effectively reduce vital communication cost, bandwidth issues, storage, data transmission cost and effective timely judicious analysis over the occurred activities and keep protection by using effective encryption methodology to remain attack free from any attacker or adversary, and provide confidentiality about patient’s privacy in the smart healthcare system.

Published: November 2020

Building energy consumption (BEC) prediction is very important for energy management and conservation. This paper presents a short-term energy consumption prediction method that integrates the Fuzzy Rough Set (FRS) theory and the Long Short-Term Memory (LSTM) model, and is thus named FRS-LSTM. This method can find the most directly related factors from the complex and diverse factors influencing the energy consumption, which improves the prediction accuracy and efficiency. First, the FRS is used to reduce the redundancy of the input features by the attribute reduction of the factors affecting the energy consumption forecasting, and solves the data loss problem caused by the data discretization of a classical rough set. Then, the final attribute set after reduction is taken as the input of the LSTM networks to obtain the final prediction results. To validate the effectiveness of the proposed model, this study used the actual data of a public building to predict the building’s energy consumption, and compared the proposed model with the LSTM, Levenberg-Marquardt Back Propagation (LM-BP), and Support Vector Regression (SVR) models. The experimental results reveal that the presented FRS-LSTM model achieves higher prediction accuracy compared with other comparative models.
