Published: June 2020

Thrust testing units with a piezoelectric dynamometer have unique traits such as excessive stiffness, tremendous measurement accuracy, dynamic performance and no hysteresis. These are widely used in the applications requiring force/thrust measurements in the aerospace industry and high‐end tool condition monitoring. The performance of these units is necessary to be evaluated. In this study, an improved layout of six‐degree of freedom force/thrust measurement stand is proposed and analysed theoretically and experimentally. The measurement stand is a structural component to measure six components of force, such as axial force/thrust (FX, FY, and FZ ) and other components (MX, MY, and MZ ). Test stand consists of seven piezoelectric sensors in two sections. The front part consists of four piezoelectric force sensors, while the rear part consists of three sensors. The rear section is hexagonal, with three sensors mounted at 120°. The measurement stand can measure the principal force/thrust up to 50,000 N. A mathematical model is derived for every sensor against forces in all directions. To calibrate the stand, a calibration platform is designed and fabricated. The calibration platform can generate a range of forces/moments. Calibration experiments verifies that the measurement stand is fairly functional to measure variety of forces/moments with high repeatability.

ZusammenfassungEinleitung Die Hypothermiebehandlung (TH) verbessert bei Neugeborenen mit hypoxisch-ischämischer Enzephalopathie (HIE) das Outcome und sollte bei Hinweisen für eine perinatale Asphyxie und Zeichen einer moderaten oder schweren HIE angewendet werden.Material/Methode Die Häufigkeit der HIE und der Anwendung der TH wurde aus den Daten der Neonatalerhebung und den Daten des 2010 etablierten Hypothermieregisters extrahiert. Letztere wurden darüber hinaus zur Analyse des kurzfristigen Outcomes herangezogen.Ergebnisse Zwischen 2010 und 2017 schlossen sich 106 der 213 (Stand März 2020) deutschen Perinatalzentren dem Register an. Die Rückantwortquote lag zwischen 22 und 60%. Im Register wurden pro Jahr im Median 164 (IQR 115–224) TH bei Neugeborenen mit HIE erfasst, in der Neonatalerhebung 517 (382–664) bei 543 (432–583) Fällen von HIE. Seit 2014 lag die Zahl der TH über den berichteten Fällen von HIE. Nach TH bei klassischer Indikationsstellung verstarben 10,4% (8–13%) der Neugeborenen. 81% (78–82%) der Neugeborenen wurden nach Hause entlassen, 3,6% (3–5%) in eine Rehabilitationseinrichtung bzw. 5,4% (5–7%) in eine andere Klinik verlegt. Bei Entlassung wurden 89% (87–89%) der Patienten ausschließlich oral ernährt.Diskussion Nach Etablierung der TH in die klinische Routine stieg die Zahl der behandelten Neugeborenen kontinuierlich an. Aktuell liegt die Zahl der TH über der Anzahl der Neugeborenen mit HIE, was nur schwer zu erklären ist, da das Vorliegen einer moderaten oder schweren HIE Voraussetzung für die TH ist. Die Daten des Hypothermieregisters zeigen für den untersuchten Zeitraum keine deutlichen Veränderungen bezüglich Mortalität oder neurologischem Outcome.

Abstract
Objectives The aim of this study was to compare the effects of two margin designs (shoulderless and slight chamfer) with two occlusal thicknesses on fracture resistance and failure mode of the monolithic zirconia crowns.
Materials and Methods Forty nickel–chromium dies were duplicated from the previous two prepared teeth using a three-dimensional optical scanner. Nickel–chromium supporting dies were divided into two main groups (n = 20) according to the type of margin design: group A, slight chamfer margin design and group B, shoulderless margin design. These groups were further divided into two subgroups according to the occlusal thicknesses (0.5 and 1 mm). The digital imaging of each die was done using a three-dimensional optical scanner, then zirconia blocks were milled by 5-axis machine. The crowns were cleaned by alcohol, air dried, and cemented by resin cement. Next, the crowns were subjected to 500 hot and cold cycles (30 seconds for each cycle). The samples were subjected to a static load until failure using an electronic universal testing machine and fracture resistance was recorded in Newton (N).
Statistical Analysis Data were analyzed using the test of normality (Shapiro–Wilk test) and two-way analysis of variance (ANOVA) test.
Results  The highest mean fracture load was recorded by the shoulderless (1 mm occlusal thickness) subgroup (3,992.5 N), followed by shoulderless (0.5 mm occlusal thickness) subgroup (3,244.4 N), and the slight chamfer (1 mm occlusal thickness) subgroup (2,811 N). The lowest mean of fracture load was recorded by slight chamfer (0.5 mm occlusal thickness) subgroup (1,632.9 N). The two-way ANOVA test revealed a significant difference between the four subgroups. Regarding the fracture mode, the slight chamfer subgroups showed a severe fracture of the restoration while the shoulderless subgroups showed a fracture through the midline of the restoration.
Conclusion Within the limitation of the comparative study, shoulderless margin design has a more favorable outcome than a slight chamfer design in all thicknesses. Although the restoration with reduced occlusal thickness has lower fracture resistance than 1 mm occlusal thickness, the 0.5 mm restorations still can tolerate occlusal forces.

AbstractWomen in India perform a range of roles in wheat-based agricultural systems. However, data remain sparse. Cultural norms which construct men as farmers serve to conceal women’s contributions from researchers and rural advisory services. We use data from communities in four Indian states, selected to exemplify high and low gender gaps, to provide insights into how women are challenging norms which privilege male decision-making in order to participate in innovation processes. We hypothesized the transitioning of women from labourers in wheat to innovators and managers of wheat is likely to be far from straightforward. We further hypothesized that women are actively managing the processes unleashed by various sources of change. We use the concept of doxa—ideas and actions in a society that are taken for granted and are beyond questioning—as an analytic lens to help us understand the ways in which women deploy their agency to secure their goals. Our analysis allows us to develop a ‘A typology of women’s strategies to strengthen their managerial decision-making power in wheat’.
Covert hate speech
Authors: Baider Fabienne , Constantinou Maria 
Published: June 2020

AbstractPrevious research on extremist discourse has revealed that racism is linguistically shaped by its socio-cultural context. For instance, a comparison between Greek Cypriot and Greek online data indicated that the two communities use different linguistic means and strategies to express their aversion to the Other, and that Greek comments are more overtly insulting than Greek Cypriot comments (Baider and Constantinou 2017a;Assimakopoulos and Baider 2019). The present study focuses on how irony is used to disseminate hate speech, albeit covertly. Our dataset comprises online Greek and Greek Cypriot comments posted on social media and collected during the same period of time (2015- 2016) within an EU project. We use concepts such asverisimilitudeandovert untruthfulnessto deconstruct ironic racist comments. We conclude that irony in both datasets fulfils three socio-pragmatic functions: it serves to insult or humiliate members of groups targeted for their ethnic identity; it creates or reinforces negative feelings against such groups; it promotes beliefs that could be used to legitimate their mistreatment. Regarding socio-cultural differences, it emerges that the use of the Greek Cypriot vernacular and the appeal to indigenous in-group social stereotypes influence the way irony shapes racist comments and reinforces in-group membership.

Abstract
Inventory management is the main task of an organization to reach its objective of maintaining the number of stocks precisely and minimizing waste. Web-based inventory management in a university environment is expected to help the employees in keeping up with innovations on the status of tools and equipment. It is only fitting that inventory data management is also capable of accommodating distance. The use of the internet by using mobile computing which automatically can do tagging of inventories including information about the coordinate will broaden the potential of database using mobile computing technology with wireless data communication aided with 2D-barcode decoding automatization makes it possible to synchronize (record and track) on-line to the central database using some computers that work simultaneously and directly from the field. This inventory system can synchronize data directly from the field and the information can simultaneously be accessed by the users. Mobile computing (android Smartphone, computer tablet) is used as a mobile station that is capable of decoding the tags of inventories and buildings (in the 2D-barcode) and associating automatically with the database wireless networks and the internet to eliminate the distance factor and overhead-process (pre-processing of data from the field to the data storing station).

Published: June 2020

Abstract
Government policies related to electronic transactions provide many positive responses. Throughthis policy, government services relating to authentication such as population documents can be done electronically while still paying attention to their validity. In the current service process, the document archive is less organized both in village and sub-district offices and the completion of documents is hampered for days because the officials are not available. To overcome this, a system that can overcome these problems is needed. In this system, the validity of the document was still observed by digital signing using an electronic certificate (.p12). Then, the development of this system was conducted using the waterfall model. There were three tests carried out namely the black-box test, white-box, usability testing using the system usability scale, and the user response test. The development of this system has passed the black-box test and white-box test, the overall results were in line with expectations. As for the usability scale system, the results of the category are acceptable. Then the user response test was conducted on five user roles and obtained the results with an average percentage that is in very good range.

Published: June 2020

Abstract
Building is a physical form of construction work which is integrated with its domain, partly or fully on the surface and / or underneath the land and / or water, which functions as a place for people to carry out their activities. Buildings must be able to fulfill their functions. However, over the course of time and utilization, they will suffer from damage caused by various aspects, such as the mechanical components of the building. One of the efforts that can be done to reduce the damage is by doing preventive maintenance work. Preventive maintenance work includes tasks or measures taken to prevent the need for repairs. In the buildings preventive maintenance process, the scope of work can be arranged by using Work Breakdown Structure (WBS), hence a structured and activity oriented grouping can be achieved. However, in the application of government buildings there are no guidelines for WBS-based preventive maintenance work yet. Therefore, developing preventive maintenance work guidelines to improve care and maintenance performance is an important task in project management. The research methodology consisted of several stages, namely the literature study, archives analysis with data and information from previous research and related projects, case studies, and Delphi techniques through the validation of experienced experts. The result of this research was that WBS-based preventive maintenance work guidelines for mechanical components of government buildings could improve the quality of buildings and the effectiveness and efficiency of building maintenance.

Published: June 2020

Abstract
As one of vocational education in Indonesia, Politeknik Mekatronika Sanata Dharma must be able to produce graduates who are competent and skilled in the field of mechatronics. In order to achieve this, practical and workshop learning must be given a large portion. However, some practical tools available are limited, due to constraints in the cost of procuring equipment that is quite expensive. This paper presents an active learning through the practice of developing a simple industrial control simulation program, using Proteus and LabVIEW software. One example of the control simulation presented here is the control on the conveyor as a supplier of items. From the observation and learning evaluation, it was found that by making a simple simulation program, students more easily develop skills in mathematics, logical thinking and problem solving. The effectiveness of learning can be measured from the value of student satisfaction and involvement, which in the example here is quite high. Students were enthusiastic and involved, starting from the design of the conveyor simulation image, making the simulation circuit in Proteus, programming the microcontroller, and making the simulation program at LabVIEW, even to realizing it to the actual conveyor.

Abstract
The student-centered learning method is in line with the attitude of teachers and students who must be responsive in following and mastering the development of science and technology. This study aims to determine the effect of mind mapping learning methods on students’ understanding of concepts. The population in this study was Grade 10 Information and Communication Technology in Odd Semester 2019/2010 at SMK Wira Harapan, Bali, Indonesia. The samples in this study were 35 students. Data analysis was conducted using Paired T-Test Sample Test. The results showed that the application of the mind mapping learning method was able to increase the value of the learning outcomes of Computer System subjects from mean 76 to 87. With a 95% confidence level the results showed that this method was positively and significantly correlated with 47% student learning outcomes. The mind mapping learning method needs to be applied to subjects, which require more understanding based on logic understanding. Efforts to increase learning outcomes must also pay attention to the characteristics of students and other factors.
