Increasing digitalisation is fundamentally changing the understanding and possi-bilities of value creation as well as labour organisation. The systematic collection, storage and analysis of data is becoming a decisive competitive factor and is the basis for intelligent products, processes and production technology. This results in new competence requirements and roles in mechanical and plant engineering and in the manufacturing industry in general. Machine Learning in particular, as the basis of Artificial Intelligence, poses great challenges for companies, as the demand for experts, so-called Data Scientists, significantly exceeds the offer and furthermore, these experts rarely have the required domain knowledge - the core competences of manufacturing companies. In this context, the new job descrip-tion of the Citizen Data Scientist as a link between the most important disci-plines of information technology, domain knowledge and data science enters the focus of attention. The article presents a role model as a basis for team building and systematic development of required competences in the manufacturing in-dustry and combines the results of various research projects and industrial im-plementations. For this purpose, competences of the future are derived in sec-tion 1 and transferred into a transdisciplinary role model in section 2. Section 3 addresses the exemplary practical application in an industrial use case, while section 4 gives an outlook on the possibilities of target-oriented competence development for the individual roles and actors.

Published: September 2021

The purpose of this research is to aggregate and discuss the validity of challenges and design guidelines regarding industrial Virtual Reality (VR) training applications. Although VR has seen significant advancements in the last 20 years, the technology still faces multiple research challenges. The challenges towards industrial VR applications are imposed by a limited technological maturity and the need to achieve industrial stakeholders' technology acceptance. Technology acceptance is closely connected with the consideration of individual user requirements for user interfaces in virtual environments. This paper analyses the current state-of-the-art in industrial VR applications and provides a structured overview of the existing challenges and applicable guidelines for user interface design, such as ISO 9241-110. The validity of the identified challenges and guidelines is discussed against an industrial training scenario on electrical safety during maintenance tasks.

Musculoskeletal disorders are the major cause for incapacity for work in the Ger-man production industry. Accordingly, ergonomic work processes are particularly important in order to protect the health of employees and to reduce the high follow-up costs for companies and society. Therefore, on the one hand, it is necessary to make workplaces more ergonomic (so-called organisational prevention). On the other hand, employees need to be trained how to carry out work processes as ergonomically as possible and thus optimise their individual behav-iour at the workplace (so-called behavioural prevention). The article presents a learning assistance system for ergonomic be-havioural prevention in production that uses modern motion capture systems to record and analyse the movements of employees. With the help of digital human models, it is possible to visualise overload on the body comprehensively. The learning assistance system ena-bles the employee to perform two primary analyses: A capability analysis allows to measure and assess a worker’s individ-ual mobility with 14 standardised movement exercises and to esti-mate his or her strength with a grip strength measurement. The as-sessment of the results strengthens health literacy in the way that the worker becomes aware of possible physical limitations and can initiate general countermeasures, such as strength or mobility train-ing. An analysis of the specific work processes at the workplace makes it possible to record the workplace-induced stress of a worker and compare it with the worker’s capabilities. This comparison leads to the workplace-specific strain and shows which movements are par-ticularly critical for the health of the individual worker. It enables the worker to recognise the critical work processes and postures of his or her work spectrum, to initiate work-specific measures to in-crease the capabilities and to ergonomically improve the working posture. The latter is the main purpose of the learning assistance system. The use of a motion capture system permits to repeat critical work steps effortlessly in order to show the effect of a more ergo-nomic working posture. These short learning cycles can be repeated until the strain is not critical anymore.

This study aimed to evaluate the public knowledge and attitude toward how to use, store and discard unused and expired pharmaceutical drugs among the Saudi population. A descriptive cross-sectional study design was used to evaluate the knowledge, attitude, and practice of participants toward the usage and disposal of expired pharmaceutical products among the Saudi population via an online survey distributed throughout social media sites during the period of two months from March 2020 to May 2020. Microsoft Excel and graph pad software analyzed the cleaned data. Descriptive statistics on sample characteristics were computed in frequencies and percentages and presented using tables and figures. 650 participants enrolled in the study. 75% of the participants had unused medicine stored at home during study time. The common types of medications kept in households were analgesics (90%) and antibiotics (67%). Most participants showed a well understanding of medication waste (70%) and the potential risks associated with improper drug disposal (85%). There was a lack of received information about safe usage, storage, and disposal practice. About 55% of the participants discarded the unused and expired medications by throwing them in the trash. In light of this study's results, which showed a large percentage of participants kept unused or expired medications in their homes despite their knowledge of the seriousness of this situation. Therefore, it is essential to plan educational programs about the rational use and expiry date of drugs to improve their awareness, attitudes, and practices regarding the safe disposal of unused and expired medications. Guidelines on safe disposal are required, and an organized method of collecting unused and expired pharmaceuticals such as the "drug take-back program" is needed. The pharmacist also has a significant role as a drug expert in educating patients about the drug's uses and how to store and discard it. Keywords: Knowledge, attitude, expired pharmaceutical drugs.
“Gastrointestinal” comorbidity in irritable bowel syndrome
Authors: Gaus O. V. , Livzan M. A.
Published: September 2021

Among the large and heterogeneous group of patients with irritable bowel syndrome (IBS) comorbidity is characteristic feature. Comorbidity is an urgent problem in real clinical practice. Gastrointestinal comorbidity of a patient with IBS is associated with the presence of common pathogenetic links and is represented by combined pathology with functional disorders and the formation of “overlap syndrome” with organic diseases. Often, with a comorbid course, the phenomenon of “mutual burdening” is observed, when the severity of the course of each of them increases. All this requires optimization of approaches to the diagnosis and treatment of this cohort of patients. Obviously, with a comorbid course of IBS, it is advisable to prescribe drugs that affect the general links of pathogenesis, rather than focusing on individual symptoms. This article presents modern information on the gastrointestinal comorbidity of a patient with IBS.

Introduction. The prevalence of colorectal cancer in the world is increasing every year. In more than 40% of patients, the disease debuts with a clinical picture of acute intestinal obstruction, while in one third of cases the tumor is located in the right half of the colon. This leads to the necessity to perform colon resection or bypass surgery, the main stage of which is making entero- colic anastomosis. However, up to 15% of these anastomoses has a leakage. Development of methods of forming a reliable anastomosis is thus critical.

Materials and methods. 37 patients with acute intestinal obstruction, divided into 2 groups (17 and 20 people), are included into the study. All of them, as a surgical stage of treatment, underwent a right hemicolectomy with the formation of an entero- colic anastomosis or a bypass surgery. A double-row side-to-side anastomosis was used in the comparison group, and a single-row “end-to-side” anastomosis in the main group (patent No. 2709253). The incidence of anastomotic leakage and mortality were assessed. Comparison was performed using Fisher’s exact test.

Results. There were no cases of anastomotic leakage and mortality in the main group. In the comparison group, there were 5 leakages and 1 death.

Discussion. When a modified entero-colic anastomosis is formed, adequate blood flow is maintained in the walls of the anastomosed intestinal loops, which contributes to adequate regeneration.

Conclusion. The first clinical experience with the modified end-to-side entero- colic anastomosis is successful. It is planned to further recruit patients and study the features of the postoperative period.

Modeling and Monitoring Erosion of the Leading Edge of Wind Turbine Blades
Authors: Duthé Gregory , Abdallah Imad , Barber Sarah , Chatzi Eleni
Published: September 2021

Leading edge surface erosion is an emerging issue in wind turbine blade reliability, causing reduction in power performance, aerodynamic loads imbalance, increased noise emission and ultimately additional maintenance costs, and if left untreated, leads to the compromise of the functionality of the blade. In this work, we first propose an empirical spatio-temporal stochastic model for simulating leading edge erosion, to be used in conjunction with aeroelastic simulations, and subsequently propose a deep learning model trained on simulated data, which aims to monitor leading edge erosion by detecting and classifying the degradation severity. The main ingredients of the model include a damage process that progresses at random times, across multiple discrete states characterized by a non-homogeneous compound Poisson process, which is used to describe the random and time-dependent degradation of the blade surface, thus implicitly affecting its aerodynamic properties. The model allows for one, or more, zones along the span of the blades to be independently affected by erosion. The proposed model accounts for uncertainties in the local airfoil aerodynamics via parameterization of the lift and drag coefficients curves. The proposed model is used to generate a stochastic ensemble of degrading airfoil aerodynamic polars, for use in forward aero-servo-elastic simulations, where we compute the effect of leading edge erosion degradation on the dynamic response of a wind turbine under varying turbulent input inflow conditions. The dynamic response is chosen a defining output as this relates to the output variable that is most commonly monitored under a Structural Health Monitoring (SHM) regime. In this context, we further propose an approach for spatio-temporal dependent diagnostics of leading erosion, namely, a deep learning attention-based Transformer, which we modify for classification tasks on slow degradation processes with long sequence multivariate time-series as inputs. We perform multiple sets of numerical experiments, aiming to evaluate the Transformer for diagnostics and assess its limitations. The results reveal Transformers as a potent method for diagnosis of such degradation processes. The attention-based mechanism allows the network to focus on different features at different time intervals for better prediction accuracy, especially for long time-series sequences representing a slow degradation process.
SCALa: A blueprint for computational models of language acquisition in social context
Authors: Tsuji Sho , Cristia Alejandrina , Dupoux Emmanuel
Published: September 2021

Theories and data on language acquisition suggest a range of cues are used, ranging from information on structure found in the linguistic signal itself, to information gleaned from the environmental context or through social interaction. We propose a blueprint for computational models of the early language learner (SCALa, for Socio-Computational Architecture of Language Acquisition) that makes explicit the connection between the kinds of information available to the social learner and the computational mechanisms required to extract language-relevant information and learn from it. SCALa integrates a range of views on language acquisition, further allowing us to make precise recommendations for future large-scale empirical research.
Emotional arousal lingers across time to bind discrete episodes in memory
Authors: Clewett David , McClay Mason
Published: September 2021

Temporal stability and change in neutral contexts can transform continuous experiences into distinct and memorable events. However, less is known about how shifting emotional states influence these memory processes, despite ample evidence that emotion impacts non-temporal aspects of memory. Here, we examined if emotional stimuli influence temporal memory for recent event sequences. Participants encoded lists of neutral images while listening to auditory tones. At regular intervals within each list, participants heard emotional positive, negative, or neutral sounds, which served as ‘emotional event boundaries’ that divided each sequence into discrete events. Temporal order memory was tested for neutral item pairs that either spanned an emotional sound or were encountered within the same auditory event. Encountering a highly arousing event boundary led to faster response times for items encoded within the next event. Critically, we found that highly arousing sounds had different effects on binding ongoing versus ensuing sequential representations in memory. Specifically, highly arousing sounds were significantly more likely to enhance temporal order memory for ensuing information compared to information that spanned those boundaries, especially for boundaries with negative valence. These findings suggest that within aversive emotional contexts, fluctuations in arousal help shape the temporal organization of events in memory.

Developmental Idealism and a Half Century of Family Attitude Trends in the United States
Authors: Allendorf Keera , Young-DeMarco Linda , Thornton Arland
Published: September 2021

This paper examines a half century of trends in family attitudes and beliefs in the United States, including attitudes towards gender, marriage, childbearing, cohabitation, sex outside marriage, divorce, and same-sex relations. These trends are viewed through the lens of developmental idealism. We also describe how the developmental idealism framework applies to Western contexts generally and the United States specifically. We trace family attitudes from the 1960s through 2018 using four data sources: Intergenerational Panel Study of Parents and Children, Monitoring the Future, General Social Survey, and International Social Science Project. We find profound and largely consistent changes in Americans’ attitudes. We argue these changes can be understood as the expansion of developmental idealism in the United States. Americans increasingly endorsed family attributes long understood as modern under developmental idealism, as well as attributes more recently viewed as modern through extensions of freedom and equality. At the same time, sizable majorities remained committed to marriage and having children. While Americans increasingly supported all individuals’ freedom to choose among a diversity of family behaviors, most continued to view marriage and children favorably in their own lives.

The slaughterhouse wastewater is rich of oil and fat and it may inhabit by biosurfactant producing bacteria. Isolation of the bacteria is needed in order to find out a biosurfactant producing bacteria that can be used to maintain the oil and fat polluted area through bioremediation process. To isolate and identify the biosurfactant-producing bacteria, a study has been conducted on July to September 2020. The samples were obtained from slaughterhouse wastewater at Cipta Karya street Pekanbaru, Riau Province and samplings were conducted three times. The isolation was conducted by TSB (Tryptic Soy Broth)  and incubated for 24 hours. Then the bacterial samples were planted by TSA (Tryptic Soy Agar)  and isolated for 24 hours. Then, it was identified using biochemical and morphological tests were carried out to find out the types of bacteria. The Emulsification Index was then calculated by using TSB (Tryptic Soy Broth) and kerosene. Results shown that the emulsification index were Flavobacterium 53%, Agrobacterium 53%, Serratia 60%, Salmonella 52. 5%, Salmonella 52.4%, Proteus 65.7%, Clostridium 62% and Aeromonas 59.5%. As Proteus is shown the highest Emulsification Index, it was check using a PCR (Polymerase Chain Reaction) and it is proved that the species is Proteus vulgaris

Penelitian ini dilaksanakan pada bulan Desember 2016 s/d Februari 2017. Penelitian ini bertujuan untuk mengetahui jumlah tepung daun lemna fermentasi dalam pakan yang berpengaruh terhadap pertumbuhan dan efisiensi pakan ikan gurami (Osphronemus gouramy). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan satu faktor, lima taraf perlakuan dan tiga ulangan. Ikan yang digunakan berukuran bobot rata-rata 1,5 g dan panjang 4 cm. Ikan dipelihara dalam keramba berukuran 1 m3 dengan padat tebar 25 ekor/m3. Perlakuan pada penelitian ini adalah pemberian pakan dengan penggantian tepung kedelai dengan tepung daun lemna fermentasi, adapun perlakuannya adalah kontrol P0 (0:100%), P1 (10:90%), P2 (15:85%), P3 (20:80%) dan P4 (25:75%) untuk kandungan protein 30%. Hasil penelitian menunjukkan bahwa tepung daun lemna fermentasi berpengaruh nyata (P<0,05) terhadap pertumbuhan, efisiensi pakan dan retensi protein. Hasil penelitian ini menunjukkan bahwa protein bungkil daun lemna yang difermentasi dapat menggantikan hingga 10% dari tepung kedelai dalam pakan untuk pertumbuhan  ikan gurami.

This research is a classroom action research. The problem formulated in this study is whether through a mathematical realistic approach can improve the results of junior high school students' results on set material? The aim is to examine increasing mastery of set concepts. This research was conducted on students of class VII-C SMP PGRI Arjasari 2019/2020 school year with a total of 36 students. The instrument used was a test of learning outcomes as a test of students' mastery of mathematical concepts, for initial tests (before action), cycle I tests and II (after giving the action), and observation sheet at the time of giving and implementing the action. The results of the analysis obtained based on written tests carried out there was an increase in the average learning outcomes In the second cycle, the first meeting average value of 70.1 with the highest value of 90 and the lowest value of 45. After carrying out the actions in the second cycle of the second meeting there was an increase in the results student learning. This is seen in the average value of 80.92 with the highest value of 100 and the lowest value of 50. The percentage of classical completeness increased from the first cycle of meeting 1 by 25% and meeting 2 by 38%. Furthermore, in the second cycle also increased, at the first meeting 69% to 86%. Means that had reached more than or equal to the specified KKM 70. At the end of the first cycle student learning outcomes seen that at the end of the first cycle the percentage of learning completeness was 38% and does not meet the classical learning completeness criteria that have been determined, then the research is continued to the second cycle. After the implementation of the second cycle, shows that at the end of the second cycle learning achievement reached 86% with the number of students who completed as many as 31 students, meaning completeness based on the number of students when that is 36 people, because there are 5 people who haven't finished.
