Penerapan Asas Keterbukaan Dalam Pembentukan Undang-Undang Tentang Cipta Kerja Dan Undang-Undang tentang Ibu Kota Negara
Authors: Fadillah Nor
Published: November 2022

The purpose of this study is to analyse the decision of the Constitutional Court in the judicial review of the Job Creation Law (CK Law) and the State Capital Law (IKN Law) and to measure the principle of transparency by the Constitutional Court (MK) in the judicial review of the two laws. This is based on Law Number 12 of 2011 on the Establishment of Legislation. The research method used is normative which positions the law as a system of norms to analyze the law that has been decided by the judge through the court process. The results of the study conclude that firstly, because the CK Law is proven not to apply the principle of openness, due to the lack of public participation and information that is difficult to access by the public. The Constitutional Court decided to partially grant case number 91/PUU-XVIII-2020 by being declared formally disabled and the Job Creation Law conditionally unconstitutional. While in the IKN Law, the Constitutional Court decided to reject the entire application with case number 25/PUU-XX/2022 and stated that the principle of openness was in accordance with the constitution and the IKN Law remained in effect. Second, the Constitutional Court does not yet have a definite measure or parameter regarding the principle of openness in the examination of the Law, because there are two laws which are almost the same in their formation procedure, namely the CK Law and the IKN Law but were decided with different decisions.

Published: November 2022

Orientia tsutsugamushi is an obligately intracellular bacterium and the etiological agent of scrub typhus. Human studies and animal models of scrub typhus have shown robust type 1-skewed proinflammatory responses during severe infection. Macrophages (Mφ) play a critical role in initiating such responses, yet mechanisms of innate recognition for O. tsutsugamushi remain unclear. In this study, we investigated whether Syk-dependent C-type lectin receptors (CLRs) contribute to innate immune recognition and the generation of proinflammatory responses. To validate a role of CLRs in scrub typhus, we infected murine bone marrow-derived (Mφ) with O. tsutsugamushi in the presence of selective Syk inhibitors and analysed a panel of CLRs and proinflammatory markers via qRT-PCR. We found that Mincle/Clec4a and Clec5a transcription was significantly abrogated upon Syk inhibition at 6 hours of infection. The effect of Syk inhibition on Mincle protein expression was validated via western blot. Syk-inhibited Mφ had diminished expression of type 1 cytokines/chemokines (Il12p40, Tnf, Il27p28, Cxcl1) during infection. Additionally, expression of innate immune cytosolic sensors (Mx1 and Oas1-3) was highly induced in the brain of lethally infected mice. We established that Mx1 and Oas1 expression was reduced in Syk-inhibited M, while Oas2, Oas3, and MerTK were not sensitive to Syk inhibition. This study reveals that Syk-dependent CLRs contribute to inflammatory responses to O. tsutsugamushi. It also provides the first evidence for Syk-dependent activation of intracellular defenses during infection, suggesting a role of pattern recognition receptor crosstalk in orchestrating macrophage-mediated responses to this poorly studied bacterium.
Assigning Fair and Defensible Grades to Clinical Interns
Authors: Foutch Brian , Ferguson Amy , Coates Russell , Maki Yutaka , Summers Janet
Published: November 2022

Background: Grades in clinical courses matter. They are often used to determine clinical academic awards, scholarships, and—most importantly—interns’ suitability for graduate medical education opportunities. Aware of these stakes, clinic preceptors may feel pressure to grade too leniently or uniformly. A fair method of adjusting for differences in preceptor bias is then needed. Approach: The authors propose a technique that employs the advantages of both criterion- and normative-based grading to adjust for differences in both grader leniency and uniformity. Evaluation: The technique produces fair adjustments to any raw assign grades, and the authors demonstrate how easily this process can be administered in any clinical setting where multiple preceptors are evaluating interns. Implications: This work provides a grading framework that is transparent to all stakeholders but places responsibilities at the appropriate level. That is, clinic performance evaluations are left to clinic preceptors but grading to clinic academic managers.
Energy and Information Fluxes at Upper Ocean Density Fronts
Authors: Cornejo Pablo , Bahamondes Adolfo
Published: November 2022

We present large eddy simulations of a mid-latitude open ocean front using a modified state of the art computational fluid dynamics code. We investigate the energy and information fluxes at the submesoscale/small-scale range in the absence of any atmospheric forcing. We find submesoscale conditions (Ro∼1, Ri∼1) near surface, within baroclinic structures related with partially imbalanced frontogenetic activity. Near surface, the simulations show a significant scale coupling on scales larger than ∼103(m). This is manifested as a strong direct energy cascade and intense mutual communication between scales, where the latter was evaluated using an estimator based on Mutual Information Theory. At scales smaller than ∼103(m) the results show near-zero energy flux, however, at this scale range, the estimator of mutual communication still shows values corresponding with a significant level of communication between them. This fact motivates to investigate the nature of the self-organized turbulent motion at this scale range with weak energetic coupling but where communication between scales is still significant and to inquire into the existence of synchronization or functional relationships between scales with emphasis on eventual underlying non-local processes.
A Closed-From Parametrization and an Alternative Computational Algorithm for Approximating Slices of Minkowski Sums of Ellipsoids in R3
Authors: Fahim Golestaneh Amirreza
Published: November 2022

The current work aims to develop an approximation of the slice of Minkowski sum of finite number of ellipsoids, sliced up by an arbitrarily oriented plane in Euclidean space $\mathbb{R}^3$ that, to the best of the author's knowledge, has not been addressed yet. This approximation of the actual slice is in a closed form of an explicit parametric equation in the case that the slice is not passing through those zones of the Minkowski surface with high curvatures, namely the "corners". At corners with high curvatures an alternative computational algorithm is introduced in which a family of ellipsoidal inner and outer bounds of the Minkowski's sum are used to construct a "narrow strip" for the actual slice of Minkowski sum. This strip can narrow persistently for a few more number of constructing bounds to precisely coincide on the actual slice of Minkowski sum. This algorithm is also applicable to the cases of slice of Minkowski sum of ellipsoids with high aspect ratio. In line with the main goal, some ellipsoidal inner and outer bounds of the Minkowski sum are reviewed, including the so called "Kurzhanski's" bounds. Also some ellipsoidal approximations are suggested for the Minkowski sum, which they can be used, as well as the inner and outer bounds, in calculation of the suggested parametric approximation of the slice of Minkowski sum.

Published: November 2022

Genome-scale metabolic models (GEMs) play an important role in the phenotype prediction of microorganisms, and their accuracy can be further improved by integrating other types of biological data such as enzyme concentrations and kinetic coefficients. Enzyme-constrained models (ecModels) have been constructed for several species and were successfully applied to increase the production of commodity chemicals. However, there was still no genome-scale ecModel for the important model organism Bacillus subtilis prior to this study. Here, we integrated enzyme kinetic and proteomic data to construct the first genome-scale ecModel of B. subtilis (ecBSU1) using the ECMpy workflow. We first used ecBSU1 to simulate overflow metabolism and explore the trade-off between biomass yield and enzyme usage efficiency. Then, we simulated the growth rate on eight previously published substrates and found that the simulation results of ecBSU1 were in good agreement with the literature. Finally, we identified target genes that enhance the yield of commodity chemicals using ecBSU1, most of which were consistent with the experimental data, and some of which may be potential novel targets for metabolic engineering. This work demonstrates that the integration of enzymatic constraints is an effective method to improve the performance of GEMs. The ecModel can predict overflow metabolism more precisely and can be used for the identification of target genes to guide the rational design of microbial cell factories.

Authors: Andreev Vyacheslav Viktorovich , Andreeva Olga Vyacheslavovna , Gai Vasiliy Evgenievich
Published: November 2022

The modeling of the process of destruction of structural materials under cyclic loads in the field of high-cycle fatigue was considered. A phenomenological analysis of the main stages of the formation of cracks, mechanisms and schemes of their initiation, formed in the process of destruction of real objects, was carried out. The implementation of these mechanisms using the tools of the percolation theory made it possible to increase the reliability of modeling the processes occurring in real conditions during the destruction of a structure. The parameter of the model of damage accumulation on the images of the microstructure of the surface of metals and alloys was formulated, which makes it possible to detect the moment of completion of the formation of a crack. The fractal dimension of the percolation cluster obtained on the cells belonging to the damage was chosen as a parameter. To calculate the sizes of percolation clusters the Hoshen – Kopelman multiple labeling algorithm was used. The existing algorithm was supplemented with an auxiliary label for open cells belonging to the percolation cluster, which made it possible to get rid of the additional operation of comparing labels and re-marking nodes when combining parts of a single cluster. To confirm the effectiveness of the proposed parameter, simulation the process of damage accumulation on images of the surface microstructure was made. The magnitude of the error did not exceed 6.6% for calculations using the values of the fractal dimension of percolation clusters built on the cells belonging to the crack.
External Control of ParaView Visualization

Published: November 2022

3D visualization is essential for many industrial applications. For instance, in the oil and gas industry, the visualization of reservoirs and their associated wells helps petroleum engineers to develop exploration and production strategies. For that purpose, there are integrated domain- oriented commercial software solutions. However, their 3D visualization part has significant limitations due to their closed source nature and dedicated domain. An alternative is to use general purpose open-source visualization platform such as ParaView. The challenge is to be used seamlessly in combination with in-house data management system which needs an integration effort. Embedding one application into another requires significant effort of programing, especially, when the technology stack of the data management application is different from the one ParaView is built on. In this study we present the solution of using ParaView along with a hypothetical corporate data-management application without embedding one into another. The inter-process communication protocol is based on ParaView Python API. The proposed approach allows using the full power of ParaView and data management application with minimal integration efforts.

Published: November 2022

Biomedical research is of great importance in modern medicine. The development of an interface for the intellectualization of medical research in microscopy is a relevant and practically significant task, since the creation of an effective and user-friendly UX/UI system design makes it possible to work out the existing business logic and analyze the existing data security problems. In developing the interface, it was investigated how to improve the quality, simplicity and usability of the laboratory information system (LIS) by medical researchers in order to simplify the work of medical staff and increase the speed of their work in daily tasks. The influence of the target group analysis on the design of quality systems is studied and the LIS user portrait is created; the process of UI interface design for the developed system of medical images analysis is presented, the justification of the adopted stylistic solutions is made. The created interface was tested on a target group represented by the employees of one of the branches of Nika Spring multidisciplinary clinics. The novelty of the solution lies in the development of a UX/UI design for the LIS, which has no counterpart on the market.

Published: November 2022

The safety of an aircraft depends on the wing flow process, therefore, the study of air flow in various flight conditions is one of the most important parts of the design and operation of an aircraft. A hydrodynamic tube is one of the most effective means for studying the processes of aircraft flow in aerodynamics. It allows you to simulate special conditions and study flow characteristics that cannot be studied in real flight. Standard flow visualization methods, such as colored jets or fine particles, allow us to obtain qualitative data on the flow behavior. But it is more important to have quantitative flow characteristics that allow you to predict the development of the process and develop recommendations on flight safety measures. In this paper, the possibility of conducting non-contact three-dimensional measurements in hydrodynamic tubes by photogrammetric methods is considered. The article presents the development of a system of remote three-dimensional measurements based on images to obtain an accurate three-dimensional visualization of the flow used to quantify the parameters of the flow of aerodynamic elements in a hydrodynamic tube. The results of experimental studies on the calibration of a three-dimensional measurement system for the case of shooting an object through two boundaries of optical media are presented. The developed method of calibration of a photogrammetric system for three-dimensional measurements in an aqueous medium has demonstrated its applicability to the problem of spatial analysis of flow flows in a hydrodynamic tube.

Published: November 2022

The paper presents the panoramic visualization of thermal fields in the discharge section of the UTRO-3 experimental device of the Lomonosov Moscow State University Faculty of Physics. The main purpose of the work was to study the heating and cooling processes in a rectangular channel region under the influence of pulsed surface high-current discharges sliding over the dielectric surface, taking into account the supersonic flow in a channel with an obstacle structures. A pulsed surface discharge initiated in a 24x48 mm channel in a high-speed flow (the delay time after the shock wave passage is up to 0.4 ms) is localized mainly in the downwind region behind the reverse step (rectangular insert). The discharge produces a pulsed (submicrosecond) energy input with a length of 30 mm in the localization zone. As a result, there is a short-term heating of the section of the channel wall adjacent to it. Using infrared thermographic imaging through the chamber quartz windows transparent to IR radiation, it was recorded in the discharge chamber that the induced discharge plasma noticeably heats the surface of the flat channel wall. Based on the obtained data of panoramic visualization with an exposure up from 100 µs, we studied the cooling time of the channel walls in the downwind region evolution, heated rapidly due to the interaction with the surface discharge plasma, at various free flow velocities.
Sub-pixel BSP images
Authors: Frolov Vladimir Alexandrovich , Shcherbakov Alexandr Stanislavovich
Published: November 2022

We propose new image representations that saves sub-pixel borders between objects. This provides a number of benefits in 4 scenarios: (1) anti-aliasing, (2) up-sampling, (3) de-noising, (4) differentiable rendering. For pixels containing borders, we store information about these borders using a small BSP tree. This allows us to restore the geometric shape of an object inside a pixel with high accuracy if is a need, for example, to significantly increase the image resolution (8-16 times). We demonstrate that the proposed method allows to save edge information with high accuracy and to make a qualitative increase in resolution with a slight increase in memory consumption relative to the original image by an average of (+1%) in typical scenarios. The scope of the proposed method is the synthesis of images in copmuter graphics.
Methodology of Visualization of non-Isothermal Mixing Processes Under the Influence of External Dynamic Forces
Authors: Sataev Alexandr Alexandrovich , Andreev Vyacheslav Viktorovich
Published: November 2022

This article considers the problem of taking into account the influence of a change in spatial orientation on thermal-hydraulic processes. To obtain the parameters of non-isothermal mixing and create a database of these processes, first of all, an experimental method was used to study these processes on a small-scale model. The obtained parameters were visualized and further graphic images were analyzed using the OpenCV library (Open Source Computer Vision Library - an open source computer vision library). A new approach to visualization of mixing processes of non- isothermal flows is proposed. The result of this analysis was the integral and local characteristics of the process of non-isothermal mixing of flows. To assess the degree of influence of a change in the nature of the problem on the integral characteristics of the process of mixing of non-isothermal flows, a series of experiments was carried out for various types of problems. The research is limited by the scale of the model, and there is also a need to develop other criteria for assessing the nonisothermal mixing of flows under the influence of external forces. The value of the article is a new approach to the evaluation of non-isothermal mixing processes. The analysis of the obtained images makes it possible to study the process of non-stationary heat transfer under the conditions of external dynamic influences and to identify areas of non-uniform mixing.

The developed methods can be scaled to analyze information events in different thematic areas.
Noise Level Estimation in Images Using Haar Wavelets
Authors: Pronkin A.V.
Published: November 2022

The paper investigates the possibility and expediency of using the Haar wavelet transform in the problem of estimating the level of discrete Gaussian noise in an image. An algorithm is proposed that uses Haar wavelets to obtain an estimate of the variance of discrete Gaussian noise in a digital image. To reduce the influence of image fragments with a large proportion of high-frequency oscillations of the useful signal, the image is divided into blocks, followed by the selection of blocks with a minimum dispersion. The proposed algorithm is compared with a method based on the use of difference operators for estimating the noise level. This method gives fairly accurate noise variance estimates and has low computational complexity. The results of estimating the variance of the noise of different intensity superimposed on the image by compared methods are presented. Based on the theoretical provisions and the results of experimental studies, it is concluded that the proposed algorithm has the best accuracy in estimating the noise level at lower computational costs.

Authors: Dmitriev Vladimir Timurovich , Baukov Andrew Alekseevich
Published: November 2022

The relevance of the task of detecting and eliminating rain and snow particles in television images taken with static cameras is shown. The procedure for detecting rain and snow particles on video images, which is supposed to be used as part of an algorithm for reducing the visibility of precipitation, has been developed. The approach developed is presented in the form of three-stage classification of frame pixels into zones with moving objects and areas of stationary background, distorted and undistorted by precipitation particles. The procedure proposed has been studied and optimal values of selected accumulated frames for its correct operation have been determined: 100 frames for video images with rain; and 140 frames for video with snow. The gain of the approach developed in comparison with known by levels of errors of the first and second kind is 0.8 % and 3.4...9.1 %. The described procedure can be used in TV systems where the delay of 3...5 seconds relative to video source is not critical.

Published: November 2022

The technology of detecting static hand gestures is considered. The technology includes four main stages of image processing: detection of palm contours; piecewise linear approximation of the palm contour; construction of the autocorrelation function (ACF) of the contour of the observed gesture; comparison of the calculated ACF with the ACF of reference gestures. Examples of identification of the main gestures with the palm using the proposed technology, as well as the resulting quantitative estimates of the similarity measure of gestures, are given. The proposed technology is characterized by high speed and lack of learning process. The presented approaches may be of interest in the construction of non-contact control systems.
Example-Based Object Detection in the Attached Image
Authors: Kharinov Mikhail Vyacheslavovich
Published: November 2022

The paper solves the problem of detecting exemplified objects in a color image. A solution provides the representation of similar objects in the same colors, and different objects in different colors. This is achieved by combining images of object examples and a target image into a single joint image, which is represented in sequential number 1, 2, ..., etc. colors. The mentioned effect is demonstrated by detecting irises and pupils in a test image. It is explained by the fact that: a) the joint image is approximated by a hierarchy of approximations in sequential color numbers; b) the hierarchy of approximations is described by a convex sequence of approximation errors (values of the total squared error ); c) due to the convexity, the approximation errors are reduced for all approximations of the joint image. In the last explanation item, it is applied the operation of combining hierarchically organized objects into a single object, which is introduced in this paper. To produce the required hierarchy of image approximations Ward's pixel clustering is used. Ward's method is generalized for image processing by parts (within pixel subsets) that provides generation of multiple proper approximation hierarchies and accelerates the calculations. To do so, the so- called split-and-merge pixel cluster CI-method is embedded into Ward's generalized method to provide a real-life minimization of the error for image approximation in a fixed number of colors.

Group Pursuit on a Plane with Modeling Detection Area
Authors: Dubanov A.A.
Published: November 2022

This article describes the pursuit model by the method of chasing a group of objects. All objects participating in the pursuit model move at a constant modulo velocity. The pursuing object moves along a certain trajectory and releases objects at specified intervals, whose task is to overtake the target by the chase method. A single target, in turn, is tasked to overtake the pursuer by the method of parallel convergence. A detection area is formed for each pursuing object. The detection area is formed by two beams. The velocity vector of an object is the bisector of the angle formed by such rays. If the target is in the detection area, then the object begins the pursuit by the chase method. If the target leaves the detection area, then the object makes a uniform and rectilinear movement. The task is to implement a dynamic model of multiple group pursuing, where each object has its own tasks, its own strategies. The model is developed using computer mathematics systems. According to the results of the research, animated images were created. Targeting methods such as the chase method, the parallel approach method and the proportional approach method are widely used in military affairs. But they, for the most part, require external control, such as pointing the target with a laser beam or satellite guidance to the target. There is no description of methods of targeting in offline mode in open sources of information. The research results may be in demand when designing unmanned aerial vehicles with elements of autonomous control and artificial intelligence.

Published: November 2022

The article considers traditional and modern approaches to the content of the academic discipline "Engineering Geometry and Computer Graphics". The need for such changes is dictated by the increased demand (including the development program "Advanced Engineering Schools") for the training of highly qualified engineering personnel. The organization of educational process for teaching the disciplines of engineering-graphic training requires appropriate software. In modern conditions, the possibility of using CAD in educational classes is determined by the condition of domestic product development. It is also proposed to introduce an applied component based on virtual reality technology into the teaching methodology. The choice of software - T-flex CAD together with T-flex VR, which will allow the student to design his or her own models for further work in the virtual environment, is substantiated. The arguments in favor of this software complex, based on the prospects and relevance of design solutions for modern engineering education, are given. A list of topics and types of classes that are appropriate to implement in the development of the mentioned discipline is formulated. As a practical example, the problem of constructing projections of a segment in electronic format for demonstration in the VR-environment is described. Conclusions are made about the prospects of implementing T-flex CAD and VR to provide the training discipline "Engineering Geometry and Computer Graphics" for students of the Aerospace Department of Perm Polytechnic University.

For the presented architectural objects the least resource intensive nodes and their bundles were selected. Nodes and their bundles in such a way as to optimally use the capabilities of programs and not overload computer resources were selected. The scripts developed in the Dynamo program for creating the presented models are briefly described. Explanations for the most significant fragments and full scripts used to work with models are given. The possibilities of the Dynamo program for visual (parametric) programming are briefly analyzed. Some possibilities of work of its bundle with Revit are studied. The two-way work of the Dynamo-Revit bundle for import-export of the model was analyzed, including when changing the code to correct the model. It is advisable to continue working in this direction in order to obtain more concise and universal algorithms (chains of nodes) that allow varying the initial data and options for the shape of plastic architectural objects.
Combinatorial-geometric Problems of Intelligent Information Technologies for Processing Graphic Documents with a Weakly Formalized Description of Objects of Various Physical Nature
Authors: Vasin D.Ju. , Rotkov S.I.
Published: November 2022

The article deals with combinatorial-geometric modern approaches to the creation and use of automatic / automated information technologies for processing complexly structured raster graphic documents with a poorly formalized description of objects. At the heart of the used combinatorialgeometric approach, the analysis of video data is considered from a unified point of view of building a hierarchy of interrelated models of description, representation of data structures and decision making, as well as highly specialized processing algorithms. At the lower level of the hierarchy, raster information is processed from a digital input device (scanners, digital video cameras, various sensors), and the upper level of the hierarchy corresponds to the description of a graphic document in terms of the corresponding subject area. The features of technologies for processing the specified class of documents are determined. The basic problems of analyzing graphic documents with a weakly formalized description of the depicted objects are formulated as problems of computational geometry on polygons (contours), broken lines and points. Combinatorial-geometric problems of image input are considered. Estimates of the time complexity of the main combinatorial-geometric algorithms are given. The issues of development of the methodological, algorithmic and software base are considered in order to further increase the efficiency of the developed software and hardware systems and automatic technologies for processing the specified class of documents.

The developed technique was tested on a limited group. The experiment was 55 people aged 18 to 25 years. The recruitment was carried out according to certain criteria: gender difference, education, artistic training. The data obtained as a result of the experiment revealed a statistically significant influence of the color factors of pictograms and their distance from the center of the stimulus. The technique was implemented and tested in the laboratory of Peter the Great St. Petersburg Polytechnic University.
Modeling Geometric Objects by Expanding the Dimensionality of Space
Authors: Konopatskiy E.V. , Rotkov S.I. , Lagunova M.V.
Published: November 2022

We consider the method of determining the exit points from the plane in the point calculus, which is analogous to the vector product of vectors in the vector calculus. It is generalized both in the direction of reducing the dimensionality of space, and in the direction of increasing it. The mathematical apparatus for determining the exit points from the space of different dimensionality is presented. The approach to modeling geometric objects with the help of points that expand the dimensionality of space has been proposed and implemented. As a result, by using the exit segment length function of different dimensionality the set of flat curves in one-dimensional simplex and spatial curves in two-dimensional ones are defined. Examples of definition of an elliptic cylinder and a spatial line on an elliptic cylinder in a planar simplex are given.
Reversibility of Modified Cyclographic Projection
Authors: Lyubchinov Evgeniy Vladimirivich , Panchuk Konstantin Leonidovich , Myasoedova Tatyana Mikhailovna
Published: November 2022

In cyclographic modeling of lines of space R3 direct and inverse problems and their solutions are known. In addition to the classic cyclographic projection, there is modified cyclographic projection of a line of space, developed on the basis of the classic one. The modified cyclographic projection has practical relevance in design of general purpose road surface forms. For this projection, the solution of the direct problem, i.e. to determine modified cyclographic projection given a curve of space (road axis), is known. In this paper, we propose a solution to the inverse problem - to restore the initial space curve given its modified cyclographic projection. The paper provides justification for solution to the inverse problem and considers on example an analytic solution to the inverse problem given second-order curves. The results of this study can be applied as the basis for development of computer-aided design systems for road surface forms, both in creation of new working surface forms, and in restoration the existing ones.

Pengumpulan data dilakukan pada 30 mahasiswa PGSD dengan isntrumen angket, observasi, dan wawancara. Uji keabsahan data dilakukan dengan triangulasi teknik, sumber, dan metode. Analisis interaktif Milles & Huberman digunakan sebagai teknik analisis data. Hasil penelitian menunjukkan bahwa: (1) mahasiswa lebih percaya diri pada praktik ketiga; (2) sebagian besar mahasiswa termotivasi oleh media teman sekelasnya; dan (3) dukungan teman sekelas mempengaruhi efikasi diri mahasiswa dalam praktik mengajar. Jadi, efikasi diri mahasiswa memiliki peran yang substansial terhadap mata kuliah micro teaching. Oleh karenanya, dosen pengampu mata kuliah juga perlu memperhatikan faktor pendukung dan penghambat perfoma mengajar mahasiswa, utamanya terkait pengkondisian situasi belajar pada perkuliahan.

Penelitian ini bertujuan untuk mengembangankan buku ajar pada matakuliah Statistika Dasar yang layak dijadikan sebagai sumber belajar oleh mahasiswa pendidikan Fisika dalam perkuliahan dan penyusunan tugas akhir. Research and Development (R&D) dipilih sebagai metode penelitian ini dan menggunakan model pengembangan ADDIE sampai pada tahap development. Pada penelitian ini, produk yang dikembangkan divalidasi dan diuji keterbacaan untuk menilai kelayakan. Sebanyak 20 orang mahasiswa pendidikan fisika dipilih menjadi sampel uji keterbacaan yang dipilih melalui teknik purposive sampling. Instrumen pengumpulan data menggunakan lembar angket validasi dan lembar angket uji keterbacaan produk. Adapun nilai rata-rata dari validator ahli materi dan ahli media adalah 93,1 dan hasil pengujian keterbacaan oleh mahasiswa pendidikan fisika diperoleh nilai sebesar 92,4. Berdasarkan data-data kuantitatif yang diperoleh dan diinterpretasikan ke dalam data kualitatif maka buku ajar Statistika Dasar untuk penelitian pendidikan Fisika masuk dalam ketegori layak untuk digunakan sebagai sumber belajar. Namun, dalam penelitian masih terdapat keterbatasan karena hanya dilaksanakan sampai tahap development sehingga perlu adanya penelitian lanjutan untuk menilai keefektifan buku ajar Statistika Dasar ini dengan cara melanjutkan ke tahap keempat yakni implementation dan tahap  kelima yakni evaluation.

The principal, as a leader, has a role and responsibility to improve the quality of education, especially in distance learning mode, which is prone to learning loss. The principal's paradigm is that the boss must change in the current era to become a servant to the school community. This is very much needed in improving the quality of managed education units. The purpose of this study is to describe the activities carried out by school principals in preparing for distance learning to obtain a policy on the evaluation seen. This study uses a qualitative descriptive approach, with data analysis using Miles and Huberman's steps. The research subject is the principal of the basic education unit in Yogyakarta. A total of 27 people. The results obtained, principals in elementary school education units in Yogyakarta have implemented distance learning following established guidelines. However, in the aspect of the care program, more action is still needed. Thus, in general, the conclusion is that the principal in the primary school education unit in the city of Yogyakarta has successfully implemented the existing guidelines.

ANALISIS FREKUENSI PENGGUNAAN ISTILAH KEAGAMAAN DALAM BUKU AJAR BAHASA INDONESIA SMA KELAS X-XII: KAJIAN BERBASIS KORPUS
Authors: Syarofi Abdullah , Nugraha Anandika Panca
Published: November 2022

Penelitian ini mengidentifikasi frekuensi istilah keagamaan dalam buku ajar bahasa Indonesia untuk siswa SMA kelas X-XII yang diterbitkan oleh Kemendikbud RI serta mengetahui apakah frekuensi tersebut mencerminkan profil demografis Indonesia berdasarkan pemeluk agama. Kajian ini menggunakan pendekatan kualitatif-kuantitatif deskriptif dengan metode corpus-based analysis. Dari 30 istilah keagamaan berfrekuensi tertinggi yang ditemukan, istilah dalam agama Islam memiliki frekuensi tertinggi, diikuti Hindu, Kristen, Konghucu dan yang terendah adalah Budha. Frekuensi tersebut tidak mencerminkan konstelasi demografis Indonesia secara komprehensif karena hanya merefleksikan muslim sebagai golongan mayoritas di Indonesia sedangkan frekuensi istilah agama lainnya tidak mencerminkan persentase pemeluk agama masing-masing.
Dados Abertos Governamentais e Mobilidade Urbana: Análise Comparada de Buenos Aires e Rio de Janeiro
Authors: Garcia Giulia , Vaz José Carlos , Matheus Ricardo , Martin Jayo
Published: November 2022

Objetivo da pesquisa: Caracterizar e interpretar as estratégias para uso e disponibilização de dados abertos de mobilidade urbana em duas metrópoles latino-americanas, Buenos Aires e Rio de Janeiro, entendidas como casos relevantes para o estudo da abertura de dados de mobilidade urbana no contexto regional, por conta de suas características e trajetórias de gestão, uso e abertura de dados.
Enquadramento teórico: Incorporou os principais modelos analíticos e explicativos sobre as estratégias e instrumentos de abertura de dados governamentais, com destaque para o modelo de Cinco Estrelas de Berners-Lee e os 15 Princípios de Dados Abertos do Opengovdata.
Metodologia: Baseou-se em um estudo de caso coletivo aplicado a dois casos, conforme Robert Stake (1995), sem prejuízo de sua expansão futura a mais casos.
Resultados: Tanto individualmente – para cada governo local – quanto nas comparações realizadas, foi possível compreender as estratégias utilizadas, bem como sua relação com o contexto e os limites e potenciais da abertura de dados nesse campo. Os casos guardam diferenças entre si, em suas políticas de governo aberto e mecanismos de dados abertos, mas também compartilham elementos comuns, como os tipos de dados de mobilidade urbana disponibilizados e a natureza de algumas estratégias e iniciativas de dados abertos adotadas.
Originalidade: Além da originalidade do modelo teórico, que pode embasar o estudo de outros casos, as análises produzidas aportam uma contribuição original para o estudo da abertura de dados em mobilidade urbana em duas significativas metrópoles latino-americanas.
Contribuições teóricas e práticas: O estudo abre caminho para a aplicação do modelo em outras cidades e para o aprofundamento do conhecimento sobre abertura de dados governamentais de mobilidade urbana.

Contexto do caso: Este caso de ensino apresenta uma situação vivenciada no setor público, apontando a complexidade de se resolver questões referentes à gestão dos bens públicos, especialmente quanto ao seu desfazimento.
Dilema do caso: No caso particular, os bens móveis não operacionais da extinta Rede Ferroviária Federal S.A. (RFFSA) foram destinados ao Departamento Nacional de Infraestrutura de Transportes (DNIT), contudo, a autarquia tem a intenção de realizar o desfazimento desses bens, haja vista serem inservíveis para o desempenho de suas atividades. O discente foi convidado a ocupar a posição da comissão de desfazimento, bem como dos gestores, indicando as possíveis ações para o reconhecimento, mensuração, evidenciação e destinação dos bens provenientes da RFFSA.
Fechamento do caso: No desfecho do caso, recomenda-se que o docente expositor comente, em linhas gerais, sobre como o DNIT vem procedendo em relação ao dilema, abordando tanto as questões contábeis quanto as de escolha da modalidade de desfazimento de bens.
