Worüber Thilo Sarrazin schweigt. Herausforderungen der Politischen Bildung in der Migrationsgesellschaft
Authors: Grabbert Tammo , Lange Dirk
Published: January 2022

Der Beitrag unterzieht die von Thilo Sarrazin in seinem Buch „Deutschland schafft sich ab“ aufgestellten Thesen zunächst einer wissenschaftlichen Prüfung und formuliert Erklärungsansätze für den großen Erfolg des Buches. Dabei zeigt sich, dass die Behauptungen Sarrazins weitgehend unhaltbar sind. Da diese sich aber einer hohen Popularität erfreuen, verweist der Sarrazin-Diskurs auf elementare soziale und politische Problemlagen, die letztendlich eine Gefahr für den gesellschaftlichen Zusammenhalt und die Funktionalität der Demokratie in Deutschland darstellen können. Als zentral für die Sympathien für Sarrazins Argumente erscheinen die seinem Buch immanente Verteidigung bürgerlicher Mittelschichtswerte und –privilegien, die aufgrund eines beschleunigten sozioökonomischen Wandels zunehmend infrage gestellt werden, sowie die vermeintliche Legitimierung tief in der Gesellschaft verwurzelter Ressentiments gegenüber Minderheiten. Vor diesem Hintergrund analysiert der Beitrag bestehende Möglichkeiten und Handlungsbedarfe für entsprechende Interventionen im Rahmen der migrationspolitischen Bildung. Abschließend werden neuere didaktische Ansätze vorgestellt, deren Implementierung im Bildungssystem aufgrund der analysierten Problemlage anempfohlen wird.
Integrierte Konzernsteuerung in der Kommunalverwaltung
Authors: Lasar Andreas , Buchholz Gabriele , Hellenbrand Andreas
Published: January 2022

In den vergangenen Jahren haben viele Kommunen ihre Aufgaben aus der Kernverwaltung in verselbstständigte Aufgabenträger ausgegliedert. Dieser Trend ist trotz einzelner Rekommunalisierungen ungebrochen. Es entsteht ein konzernähnliches Gebilde. Obwohl die Kommune, insbesondere Verwaltungsführung und Politik, für die Aufgabenerfüllung auch in den ausgegliederten Einheiten verantwortlich ist, werden die verselbstständigten Aufgabenträger oftmals nicht ausreichend in die Steuerung der Kommune einbezogen. Es fehlt an einer integrierten Konzernsteuerung. Ausgehend von der Begriffsklärung und Darstellung der spezifischen Merkmale des kommunalen Konzerns werden die Problemlagen der kommunalen Konzernsteuerung beschrieben und Anforderungen an eine integrierte Konzernsteuerung in der Kommune aufgezeigt.
Articulations and Products of Transition Systems and their Applications to Petri Net Synthesis
Authors: Devillers Raymond
Published: January 2022

In order to speed up the synthesis of Petri nets from labelled transition systems, a divide and conquer strategy consists in defining decompositions of labelled transition systems, such that each component is synthesisable iff so is the original system. Then corresponding Petri Net composition operators are searched to combine the solutions of the various components into a solution of the original system. The paper presents two such techniques, which may be combined: products and articulations. They may also be used to structure transition systems, and to analyse the performance of synthesis techniques when applied to such structures.
The Complexity of Synthesis of b-Bounded Petri Nets
Authors: Tredup Ronny
Published: January 2022

For a fixed type of Petri nets τ, τ-SYNTHESIS is the task of finding for a given transition system A a Petri net N of type τ(τ-net, for short) whose reachability graph is isomorphic to A if there is one. The decision version of this search problem is called τ-SOLVABILITY. If an input A allows a positive decision, then it is called τ-solvable and a sought net N τ-solves A. As a well known fact, A is τ-solvable if and only if it has the so-called τ-event state separation property (τ-ESSP, for short) and the τ-state separation property (τ-SSP, for short). The question whether A has the τ-ESSP or the τ-SSP defines also decision problems. In this paper, for all b ∈ ℕ, we completely characterize the computational complexity of τ-SOLVABILITY, τ-ESSP and τ-SSP for the types of pure b-bounded Place/Transition-nets, the b-bounded Place/Transitionnets and their corresponding ℤb+1-extensions.
Piecewise Affine Dynamical Models of Petri Nets – Application to Emergency Call Centers*
Authors: Allamigeon Xavier , Boyet Marin , Gaubert Stéphane
Published: January 2022

We study timed Petri nets, with preselection and priority routing. We represent the behavior of these systems by piecewise affine dynamical systems. We use tools from the theory of nonexpansive mappings to analyze these systems. We establish an equivalence theorem between priority-free fluid timed Petri nets and semi-Markov decision processes, from which we derive the convergence to a periodic regime and the polynomial-time computability of the throughput. More generally, we develop an approach inspired by tropical geometry, characterizing the congestion phases as the cells of a polyhedral complex. We illustrate these results by a current application to the performance evaluation of emergency call centers in the Paris area. We show that priorities can lead to a paradoxical behavior: in certain regimes, the throughput of the most prioritary task may not be an increasing function of the resources.
Inferring Unobserved Events in Systems with Shared Resources and Queues
Authors: Fahland Dirk , Denisov Vadim , van der Aalst Wil. M.P.
Published: January 2022

To identify the causes of performance problems or to predict process behavior, it is essential to have correct and complete event data. This is particularly important for distributed systems with shared resources, e.g., one case can block another case competing for the same machine, leading to inter-case dependencies in performance. However, due to a variety of reasons, real-life systems often record only a subset of all events taking place. To understand and analyze the behavior and performance of processes with shared resources, we aim to reconstruct bounds for timestamps of events in a case that must have happened but were not recorded by inference over events in other cases in the system. We formulate and solve the problem by systematically introducing multi-entity concepts in event logs and process models. We introduce a partial-order based model of a multi-entity event log and a corresponding compositional model for multi-entity processes. We define PQR-systems as a special class of multi-entity processes with shared resources and queues. We then study the problem of inferring from an incomplete event log unobserved events and their timestamps that are globally consistent with a PQR-system. We solve the problem by reconstructing unobserved traces of resources and queues according to the PQR-model and derive bounds for their timestamps using a linear program. While the problem is illustrated for material handling systems like baggage handling systems in airports, the approach can be applied to other settings where recording is incomplete. The ideas have been implemented in ProM and were evaluated using both synthetic and real-life event logs.
Beyond facts – a survey and conceptualisation of claims in online discourse analysis
Authors: Boland Katarina , Fafalios Pavlos , Tchechmedjiev Andon , Dietze Stefan , Todorov Konstantin
Published: January 2022

Analyzing statements of facts and claims in online discourse is subject of a multitude of research areas. Methods from natural language processing and computational linguistics help investigate issues such as the spread of biased narratives and falsehoods on the Web. Related tasks include fact-checking, stance detection and argumentation mining. Knowledge-based approaches, in particular works in knowledge base construction and augmentation, are concerned with mining, verifying and representing factual knowledge. While all these fields are concerned with strongly related notions, such as claims, facts and evidence, terminology and conceptualisations used across and within communities vary heavily, making it hard to assess commonalities and relations of related works and how research in one field may contribute to address problems in another. We survey the state-of-the-art from a range of fields in this interdisciplinary area across a range of research tasks. We assess varying definitions and propose a conceptual model – Open Claims – for claims and related notions that takes into consideration their inherent complexity, distinguishing between their meaning, linguistic representation and context. We also introduce an implementation of this model by using established vocabularies and discuss applications across various tasks related to online discourse analysis.
Effect of Exit Door Width on Flow Rate in Occupant-based Fire Evacuation Scenarios in Dormitories
Authors: Yaman Muammer
Published: January 2022

Student dormitories are intensely used buildings that meet the resting, accommodation and living needs of students. It is necessary to ensure the safety of students and to eliminate possible risks in dormitories as intensive use areas. Fires pose a great risk in dormitories and may cause serious casualties and injuries. The reduction of casualties and injuries can be achieved by analyzing occupant behaviour during fires according to the building use scenarios. In this paper, a type of dormitory that provides two alternative exits is explored. The building use scenarios of the dormitory were investigated by making on-site observations. Students’ use of sleeping units, dining units and partial sleeping/dining units and fire exit routes were determined. Pathfinder computer program was used to analyze the fire evacuation performance. This program was defined in accordance with occupant behaviour and different fire evacuation times were suggested depending on the building use scenarios. At the end of the study, based on the evacuation times, the flow rate at the exit doors according to the location of the occupants was analyzed. In the fire escape routes, as the upper floors are reached from the lower floors, the occupant flow rate decreases at the exit doors and the flow rates continue to be stable as the number of occupants is saturated according to the door width. The decrease in the number of occupants in the dining unit decreases the flow rate at the exit doors. It is important that various assembly units in dormitories, such as the dining unit, are designed on floors that can directly provide evacuation to a safe area. The results obtained are suitable for all dormitories, residences, hotels and other similar buildings.

Socioeconomic and behavioural determinants of oral health in 6- and 7-year-old schoolchildren from Palermo (Sicily)
Authors: d'Alba Simonetta , Giuliana Giovanna , Pizzo Giuseppe , Matranga Domenica , Maltese Anna Maria , Buttacavoli Fortunato
Published: January 2022

Caries and periodontal diseases are highly neglected disease affecting millions of Italian children; both diseases are preventable and the combination of high prevalence, high morbidity and a relative lack of attention of the Italian National Health Service make caries and periodontal disease a significant public health problem. 

To date none studies reported epidemiological data of 6–7-year-old-italian-children-population.

The aim of this survey was to describe the dental and periodontal health status in 6- and 7-year-old schoolchildren from Palermo and to evaluate the association between socioeconomic determinants and behavioural habits. 

A sample of 2701 children aged 6 and 7 from the selected public schools in all the eight districts of the town received a clinical intraoral examination carried out by trained dentists. Parents were asked to fill in a questionnaire investigating children’s eating habits, oral health related behaviours and socioeconomic determinants of the household.

The percentage of 6- and 7-year-old schoolchildren with at least one carious lesion was found to be 66.5%. A higher mother’s and father’s educational level were a protective factor for carious lesions; conversely, a paternal unemployment was found to be a risk factor. Living in II and VII districts was a risk factor for all stages of carious lesions.

Authors: Soerohardjo Indrawarman , Zulfiqqar Andy , Yuri Prahara , Hendri Ahmad Z.
Published: January 2022

Objective: This study aims to compare 4 years of experience of IC and TUUC in the same period and among similar experienced surgeons. Material & Methods: Between January 2016 and August 2019, 44 radical cystectomies were performed, but 4 patients were excluded due to incomplete data or who underwent neo-bladder procedures. The primary endpoint was 30 days of complication rate and intraoperative complications. Bowel movement, ambulation, and length of stay (LOS) postoperatively were followed-up over a period of 30-day postoperatively. Results: 12 male patients underwent TUUC and 24 male patients IC, while only 4 female patients underwent IC. The mean of LOS of IC was 12.72  8.6 and 10.08 3.5 for TUUC; there were no significant differences between arms. However, TUUC had lower intra-operatively bleeding (779.17  441.15 ml) compared to IC (1328.57  810.40 ml). There was no difference in early complications between arms. Conclusion: Our results suggest that TUU with UC diversion may be used as a viable option of urinary diversion in radical cystectomy. This technique provides similar safety both surgically and oncologically.

Objective: This study was conducted to find out the frequency and characteristics of urovaginal fistula patients. Material & Methods: This study design used a retrospective descriptive research design conducted at a tertiary hospital in West Java, Indonesia (Hasan Sadikin General Hospital) from 1 January 2010 to 31 December 2016. Results: Of all 22 urovaginal fistula patients, the majority in the age range of 41-50 years, and there was one patient in the age range of 61-70 years. Fourteen patients (63.6%) had defects in the bladder, and 36.5% of patients had defects in the ureters. There were nine patients (40.9%) who had urovaginal fistula after undergoing a hysterectomy procedure. The other causes were cervical carcinoma (40.9%), difficult labor (9.1%), radiotherapy (4.5%), carcinoma rectum (4.5%), cesarean section procedure (9.1%), and other gynecological procedures such as myomectomy or cystectomy (9.1%). Based on the type and location of the fistula, the majority of patients had vesicovaginal fistula/VVF (59%), ureterovaginal fistula/UVF (36%), and a combination of ureterovesicovaginal fistula (5%). The causes of VVF and UVF are different from each other. In patients with VVF, the most common cause is cervical carcinoma (35.7%). Meanwhile, the most common cause of UVF is hysterectomy (75%). Conclusion: Of the various types of urovaginal fistulas, vesicovaginal fistulas are the most frequently encountered. In general, the characteristics of urovaginal fistula patients in Hasan Sadikin General Hospital is slightly different from the literature, especially the cause of fistula. At Hasan Sadikin General Hospital, vesicovaginal fistulas are mostly caused by cervical cancer, not a hysterectomy. For ureterovaginal etiology, the characteristics of patients in Hasan Sadikin General Hospital are caused mainly by hysterectomy.

Objective: To evaluate the usage of MRI in prostate cancer staging, especially in nodal involvement (N-staging) and metastasis (M-staging) of prostate cancer. Methods: This is a systematic review and meta-analysis assessing role of MRI in nodal and metastasis staging of prostate cancer. Search of studies were done through search engine using Pubmed, Cochrane, and EBSCO Host and manual searching. Quality of eligible studies were assessed using a revised version of Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) and analyzed in pooled analysis according to nodal involvement or metastasis staging, modality of diagnosis used as the index test and gold standard used using STATA version 13. Results: Total 26 studies corresponding with study’s eligibility criteria were found. Overall, usage of MRI has a sensitivity of 47% (95% CI 35% - 60%; I2 83.08%) and a specificity of 93% (95% CI 89% - 96%, I2 82.21%) in nodal involvement staging of prostate cancer, while using of MRI in M-staging of prostate cancer shows a sensitivity of 94% (95% CI 86% - 97%) and a specificity of 99% (95% CI 97% - 99%). Using lymphotrophic superparamagnetic nanoparticle (LSN) - enhanced MRI gives higher sensitivity than using MRI without LSN for N-staging of prostate cancer. Conclusion: The usage of MRI in prostate cancer staging has a moderate sensitivity and relatively high specificity in detecting lymph node. Moreover, it plays an important role and even can be used as a modality of choice in assisting bone metastatic prostate cancer detection.

Sustainable Nutrient Management in Sugarcane Fields
Authors: Kusumawati Anna , Alam Syamsu
Published: January 2022

The state of sugar in Indonesia which is decreasing in terms of production, the imbalance between production and consumption, can occur due to two things, both on-farm and off-farm. Planting in monoculture for a long period of time will cause reduced soil fertility conditions so that sugarcane productivity decreases. Sustainable nutrient management in sugarcane plantations is an effort made to obtain optimal and profitable productivity, while still trying not to damage the environment so that it can be sustainable and its productivity can be maintained in the long term. Several concepts for sustainability have been put forward by many experts, including the use of site-specific fertilizers, maintaining soil fertility by using sugar processing by-products and the use of humic. It is hoped that some of these application methods can maintain sugarcane plantations to be sustainable.

Published: January 2022

The final project service is a supervision service from the lecturer for students who prepare the final project. Satisfactory service can be an effective promotion to prospective students. The Quality Control Group (GKM) of STMIK Indonesia Padang carries out one of their responsibilities, namely analyzing student satisfaction with final assignment services as an evaluation of the performance of final assignment supervisors and also to improve final assignment services. Therefore, we need an information system that can help GKM employees obtain accurate results to analyze student satisfaction. The system development method used is to use an object-oriented methodology. The website-based information system that was built (named WALTA (Final Project Service Satisfaction Analysis Website)) used the Likert scale measurement method to measure the level of student satisfaction with the services of the final assignment supervisor with 5 category levels, namely very satisfying, satisfying, quite satisfying, less satisfying and unsatisfactory. The existence of WALTA, GKM STMIK Indonesia Padang employees worked more effectively and efficiently because there was no need to collect students locally to fill out the questionnaire, no need to print out the questionnaire and process the questionnaire data, and the results of the questionnaire were immediately displayed on WALTA. 32 lecturers supervised the final assignment of Odd Semester 2018/2019. It was found 9 lecturers provided final assignment services with a very satisfying category and 23 lecturers with a satisfactory category. Furthermore, the results of this assessment were one of the lecturers' performance evaluation instruments.

Published: January 2022

Various normal and pathologic findings might occasionally be found on the tongue and might confuse some patients and clinician due to its atypical presentation. This case report aimed to present a case report of multiple oral findings related to variants of normal and pathological findings on the tongue: geographic tongue, fissured tongue, and central papillary atrophy. A 53-year-old male patient came to Universitas Indonesia Dental Hospital for a dental check-up. Objective examination in the tongue showed depapilated areas surrounded by keratinized lining in the ventral and lateral left and right area of the tongue, multiple fissures in all over the dorsum of the tongue, and an ovoid redness area in the middle of 2/3 posterior dorsum part of the tongue. All those findings were asymptomatic. Those clinical findings were diagnosed as geographic tongue, fissured tongue, and central papillary atrophy. This case presents unique multiple variants of normal and pathological findings in the tongue. It is important to an oral health professional to have knowledge and ability to determine normal anatomy, variants of normal and pathological lesions. Patients should be informed and educated about oral mucosa normal variations and related clinical findings so they would not develop unnecessary anxiety.

Evolutionary based system for qualification and evaluation
Authors: Szabó Ferenc János
Published: January 2022

In a previous paper the new EBSYQ (Evolutionary Based SYstem for Qualification and Evaluation of Group Achievements) system has been proposed for teachers and juries, helping them in making accurate and objective ranking. The analysis of the behaviour of the special characteristic sigmoid functions of the groups gives the possibility to discover some interesting points of view for qualifying the achievement and the standard of the groups (subgroups of talented and under- motivated students, spectrum of the group, eigenvalues, Lorentz function). This paper shows a case study of an international project of student groups competition in the field of product design, with Finnish and Hungarian students. Comparison of the decision process of the jury without using the EBSYQ system and with the application of the system shows the efficiency of the qualification system in realizing a well-founded and careful ranking of the groups, even in case of very close competition. Each point of view of the decision-making system is evaluated by numbers, which can increase the objectivity and accuracy of the decision.

Authors: Derekas Csaba , Kiss Dániel
Published: January 2022

In this paper, we present the design and construction of a rapid prototyping machine based on FDM (Fused Deposition Modeling) technology and the results of the test pieces made with it. The design basis of the machine was provided by an existing ISEL 5D milling machine, from which the two axes realizing the orientation movements were removed, and then the motion control of the three axes realizing the linear movements was realized with an Arduino Uno microcontroller. With the completed 3D printer, we printed test pieces from different raw materials and printing parameters during the testing, the results of which are reported.
Examination of possibilities of the strength modification in the case of FDM/FFF manufacturing technology
Authors: Ficzere Péter , Lukács Norbert László
Published: January 2022

In many situations the result of the topology optimization or generative design can be manufactured only by additive manufacturing technologies. It is also important to know how the optimised shape behaves from the mechanical stiffness, the manufacturing technology and beneficial point of view. These two different goals can be combined and just the infill properties can be changed and optimised within the main body of 3D printed part.

Conceptional cutting tool design for internal thread turning
Authors: Kiss Dániel , Mihályi Gergő
Published: January 2022

This article describes the different machining methods of the ball nut thread. One of the disadvantages of machining high pitch ball nuts by grinding process is to produce a modified tool profile to avoid collisions between the tool holder and the workpiece. However, by using profiled lathe inserts, it is possible to produce the thread profile of the ball nut using turning technology. The applicability of the technology is verified by tooling and experimental machining based on conceptual designs, the results of which are described at the end of the article.

Drag coefficient calculation of modified Myring-Savonius wind turbine with numerical simulations
Authors: Saleh Mahmoud , Kovács Endre
Published: January 2022

Nowadays the importance of renewable energy is growing, and the utilization of the low wind energy potential is getting crucial. There are turbines with low and high tip speed ratio. Turbines with low tip speed ratio such as the Savonius wind turbine can generate adequate amount of torque at low wind velocities. These types of turbines are also called drag machines. The geometry of the blade can greatly influence the efficiency of the device. With Computational Fluid Dynamics (CFD) method, several optimizations can be done before the production. In our paper the Savonius wind turbine blade geometry was designed based on the so-called Myring equation. The primary objective of this paper was to investigate the drag coefficient of the force acting on the surface of the blade. Also, the Karman vortex was investigated and the space ratio of that vortex in our simulation was compared to a typical one. The power coefficient of a new Savonius turbine was investigated at different values of top speed ratio (TSR). For the sake of simplicity, a 2D cross-sectional area was investigated in the simulation with ANSYS Fluent 19.2.

Project management success factors: in research of product development project specialities
Authors: Soltész László , Kamondi László , Berényi László
Published: January 2022

Project success is a multifactorial issue, including difficult to quantify, soft factors as well. Project management style, collaboration within the team, and the level of standardisation may have an essential influence on the deliverables, moreover, on corporate performance. A prescription answer is not achievable considering the individual characteristics of projects but finding best practices and critical factors help to improve the performance. This paper presents the results of a survey among product development project experts (n = 112) evaluating the relevance of some success factors and their practical experience in the field. The results show that keeping the project plan and managing long-term issues like lessons learned database or module database are the most critical factors of success. The analysis did not find patterns of the responses that confirms the need for unique management actions.

The effect of the contact zone of cylindrical helical gears on the meshing and some considerations for determining its shape
Authors: Drágár Zsuzsa , Kamondi László
Published: January 2022

The study deals with the meshing characteristics of cylindrical helical external gear pairs. The gear pairs, following the nowaday’s strength and quality requirements are becoming ever smaller. Accuracy in the background also attracts the importance of vibration and noise reduction. The inclined tooth meshing, in contrast to the straight tooth, due to the specificity of its zone of contact, is the subject of this study. This is of special importance because the meshing stiffness varies for one to more teeth pairs, the meshing contact lines are of continuously varying length during meshing, and as a consequence load sharing and distribution is changing with. This paper deals with the zone of contact and its geometric modification in order to light on a new type of vibrational excitation.
