Published: March 2021

Abstract
The realistic modeling of automatized manufacturing processes is part of the project Virtual Enterprise. Central issue of the project is the functional and shape oriented representation of a typical industrial enterprise. Based on the main business processes, the Virtual Enterprise displays the internal relations and information flows between the different departments of an enterprise (e.g. business planning, research & development, operations scheduling, manufacturing, sales etc.). The visualization of the Virtual Enterprise is realized by a virtual environment (VE) allowing the user to explore interactively the complex world of an industrial enterprise.
The paper outlines the key concepts as well as the basic architecture and the object oriented data model of the Virtual Enterprise. It describes the graphical submodels for the generation of the scene and the technical submodels for the realistic presentation of the behavior of the technical objects. The paper presents the implementation of the prototype of the Virtual Enterprise including a survey over the hard- and software configuration of the system. Goal of the prototype is the realistic representation of the manufacturing area with its machine tools, robots and transport systems. Finally the current state of work is given.
Collision Control by Graphic Simulation
Authors: Bao Zhuojun 
Published: March 2021

Abstract
In this paper the development of a function for the universally applicable collision control of kinematical mechanisms is presented for an integrated CAD/CAM system. A new method for the computer aided collision control between moving bodies starts from the computer representation model as a source of information. In solid modeling the boundary or CSG representations of components are converted into extended octrees (EO). With the extended octrees the collision control is possible on the basis of analytic 3d-geometric models. A discrete collision control is based on static min-max-tests between cubes or cuboids of EO by subdividing a given time interval into sufficiently small pieces. A dynamic and continuous collision control is realized by introduction of an effective space of a moving component for each time interval however. The effective space is determined by a novel method for modeling swept volume. Using the recursive hierarchical EO the intersection of a body with the effective space of another moving body is reduced to the intersection determination between nodes (cubes) of EO. In case of a possible collision the collision zone can be recognised and presented exactly by the intersection between relevant nodes using analytic tests. The collision recognition can be used to take measures for collision avoidance. The proposed method for computer aided collision control can be applied to the collision control in engineering design and planning of robotics, mechanics, manufacturing, assembling and disassembling processes.

Authors: Thomas Craig , Jones Helen , Whitworth-Turner Craig , Louis Julien 
Published: March 2021

Purpose: (1) To compare the sleep of female players from a professional soccer team to nonathlete controls across an in-season week and (2) to compare the sleep of core and fringe players from the same team on the night after a match to training nights. Methods: Using an observational design, 18 professional female soccer players and 18 female nonathlete controls were monitored for their sleep via wristwatch actigraphy across 1 week. Independent-sample t tests and Mann–Whitney U tests were performed to compare sleep between groups, while an analysis of variance compared sleep on training nights to the night after a match. Results: Soccer players had significantly greater sleep duration than nonathlete controls (+38 min; P = .009; d: 0.92), which may have resulted from an earlier bedtime (−00:31 h:min; P = .047; d: 0.70). The soccer players also had less intraindividual variation in bedtime than nonathletes (−00:08 h:min; P = .023; r: .38). Despite this, sleep-onset latency was significantly longer among soccer players (+8 min; P = .032; d: 0.78). On the night after a match, sleep duration of core players was significantly lower than on training nights (−49 min; P = .010; d: 0.77). In fringe players, there was no significant difference between nights for any sleep characteristic. Conclusions: During the in-season period, sleep duration of professional female soccer players is greater than nonathlete controls. However, the night after a match challenges the sleep of players with more match involvement and warrants priority of sleep hygiene strategies.
The age of dust—A new hydrological indicator in arid environments?

Published: March 2021

Abstract
Dust plays important roles in the environment, and there has been much interest in the formation, provenance, and age of the world's dust deposits. Ongoing debates are concerned with the importance of glacial grinding versus eolian abrasion and fluvial transport in the formation of silt-sized particles. Short-lived uranium-series isotopes afford new insights because they can be used both for provenance fingerprinting and for constraining the integrated age of chemical and physical weathering and subsequent transport and storage of sediments. Here we present trace element and Sr, Nd, and U-series isotope analyses from a number of Australian dusts and suspended river sediments remobilized during floods a year later. The inferred ages of the Australian dust appear to be linked to aridification and the loss of inland megalakes ∼30–120 k.y. ago. This provides preliminary evidence that the age of dust may provide a new hydrological indicator in arid environments.

Published: March 2021

The borehole sealing material is one of the key factors affecting the gas drainage effect of a borehole. This paper takes the compressive strength, fluidity, expansion rate, and setting time of the sealing material as the main research indicators and explores the influence of each key influencing factor on the performance of the high-fluid sealing material through the single factor experiment method. Using the Design-Expert 8.0.5 Trial software designed orthogonal experiments and establishing a quadratic model between liquidity and each test factor, which showed the impact of each key factor on the fluidity. Finally, by adjusting the amount of admixtures, the optimal ratio of high-fluidity borehole sealing materials was obtained. The results showed that the key factors had the following order of significance:

water
–
cement

reducing

agent
>
water
–
cement

ratio
>
retarder
>
expansion

agent

. With the water-cement ratio and the amount of water reducing agent increase, the fluidity of the material will increase; and with the increase of the retarder and expansion agent, the fluidity will decrease. In actual use, the fluidity is the main factor, but the expansion rate, compressive strength, and setting time are also considered. The optimal percentages were found for the high-fluidity borehole sealing material: a water-cement ratio of 1, along with 0.03% retarder, 0.5% water reducer, and 8% expansion agent. These research results could provide a reference for improving the performance of gas drainage borehole sealing materials and enhancing the effect of gas drainage.

Published: March 2021

Background
Cardiac sarcoidosis (CS) and giant cell myocarditis (GCM) share many histopathologic and clinical features. Whether they are parts of a one‐disease continuum has been discussed.

Methods and Results

We compared medical record data of 351 CS and 28 GCM cases diagnosed in Finland since the late 1980s and followed until February 2018 for a composite end point of cardiac death, aborted sudden death, and heart transplantation. Heart failure was the presenting manifestation in 50% versus 15% (
P
<0.001), and high‐grade atrioventricular block in 21% versus 43% (
P
=0.044), of GCM and CS, respectively. At presentation, left ventricular ejection fraction was ≤50% in 81% of cases of GCM versus in 48% of CS (
P
=0.004). The median (interquartile range) of plasma NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide) was 5273 (2782–11309) ng/L on admission in GCM versus 859 (290–1950) ng/L in CS (
P
<0.001), and cardiac troponin T exceeded 50 ng/L in 17 of 19 cases of GCM versus in 48 of 239 cases of CS (
P
<0.001). The 5‐year estimate of event‐free survival was 77% (95% CI, 72%–82%) in CS versus 27% (95% CI, 10%–45%) in GCM (
P
<0.001). By Cox regression analysis, GCM predicted cardiac events with a hazard ratio of 5.16 (95% CI, 2.82–9.45), which, however, decreased to 1.58 (95% CI, 0.71–3.52) after inclusion of markers of myocardial injury and dysfunction in the model.

Conclusions
GCM differs from CS in presenting with more extensive myocardial injury and having worse long‐term outcome. Yet the key determinant of prognosis appears to be the extent of myocardial injury rather than the histopathologic diagnosis.

AbstractBackgroundEtiologies of acute ischemic stroke in young adults are heterogeneous. Middle cerebral artery (MCA) stenosis is a common finding in Asians which may be an important cause of stroke in young adults. However, studies of stroke in young Asian populations are rare. Our study was to investigate the prevalence and outcome of young stroke patients with MCA stenosis in Chinese populations.MethodsYoung patients with MCA territory infarction between January 2013 and September 2018 were retrospectively recruited. Subjects were defined as stenosis group (MCA stenosis ≥50%) and no-stenosis group (MCA stenosis<50% or no stenosis) by their MCA stenosis. For patients in stenosis group, they were categorized as uni-MCA stenosis subgroup and multiple stenosis subgroup. Demographic data, risk factors, imaging feature and complications were compared between groups. Prevalence of MCA stenosis and risk factor score (score ≥ 2 or 3) in different age groups were investigated. Modified Rankin Scale (mRS) was used for evaluating functional outcome at discharge (unfavorable outcome: 3–6). Binary logistic regression was performed to determine independent risk factors of unfavorable outcome.ResultsTwo hundred forty-nine young stroke patients were included in our study and 110 (44.2%) patients were defined as stenosis group. 55 (50%) patients were categorized as uni-MCA stenosis subgroup and 55 (50%) were multiple stenosis subgroup. The most common traditional vascular risk factors included hypertension, hyperlipemia, smoking, hyperhomocysteinemia and alcohol consumption. Prevalence of risk factor score ≥ 2 or 3 increased with age, but not incidence of MCA stenosis. By TOAST classification, the most common etiologies were large-artery atherosclerosis (41.0%) and small vessel disease (33.7%). Compared with no-stenosis group, patients in stenosis group were more likely to have large territorial infarct, develop complications and have unfavorable outcome. No significant difference was found between patients in uni-MCA stenosis and multiple stenosis subgroups except history of stroke/TIA, risk factor score ≥ 3 and silent infarct. By logistic regression, hypertension (OR = 3.561; 95%CI, 1.494 to 8.492;p = 0.004), NIHSS scores at admission (OR = 1.438; 95%CI, 1.276 to 1.620;p = 0,000) and infarct size (p = 0.015) independently predicted unfavorable outcome.ConclusionsForty-four point two percent young Chinese adults with MCA territory infarction had MCA stenosis. Prevalence of MCA stenosis did not increase with age. Patients with MCA stenosis had worse clinical outcome, however, only hypertension, NIHSS scores at admission and infarct size were independent predictors.

AbstractBackgroundAlmost one-third of children under 5 years old in Indonesia suffer from stunting. Stunting can be prevented optimally during pregnancy as the initial phase of the first 1000 days of life. This study aims to determine the effect of nutrition and reproductive health education of pregnant women in Bogor Regency, Indonesia.MethodsA quasi-experimental study was conducted among 194 pregnant women from August to November 2019. The pregnant women were randomly selected from four different villages in Bogor Regency. The intervention group (n = 97) received 2 h of nutrition and reproductive health education in small groups (four or five mothers per group) every 2 weeks for 3 consecutive months. This interactive education was given by facilitators using techniques such as lectures, role-playing, simulation, and games. The control group (n = 97) received regular health care services. A structured questionnaire was applied to collect data consisting of maternal characteristics, nutritional and reproductive health knowledge, attitudes, and practices in the intervention and control groups. Data were analysed using t-test and chi-square analysis.ResultsPregnant women in the intervention group indicated a significant increase in knowledge, attitudes, and practices regarding nutrition and reproductive health after receiving education. The pre-test and post-test mean scores in the intervention group were 55.1 and 83.1 for overall knowledge, 40.2 and 49.0 for attitudes, and 36.2 and 40.2 for practices, respectively. In the control group, there was no significant difference between the pre-test and post-test mean scores for these three variables. There was a significant difference (P < 0.001) in the post-test mean between the intervention group and the control group, but the difference was not significant (P > 0.05) in the pre-test.ConclusionProviding nutrition and reproductive health education through small groups with interactive methods improves the knowledge, attitudes, and practices of pregnant women. This intervention has the potential to be replicated and developed for large-scale implementation by optimising collaboration between government, non-governmental organizations, and maternal and child health service providers.

Authors: Loosveld Lianne M. , Van Gerven Pascal W. M. , Driessen Erik W. , Vanassche Eline , Artino Anthony R. 
Published: March 2021

Abstract
Background
Essential to the professional development of mentors is making explicit and critically challenging the knowledge and beliefs underpinning their mentoring practice. This paper reports on the development of a survey instrument called MERIT, MEntor Reflection InstrumenT, which was designed to support mentors’ systematic reflection on the how, what and why of their practice.

Methods
In 2019, a twenty-item survey instrument was developed and piloted. Initial validation data (N = 228) were collected by distributing the survey through the authors’ network. An exploratory factor analysis (EFA) was conducted and internal consistency reliability coefficients were calculated.

Results
The Principal Axis EFA with Direct Oblimin rotation (Delta = 0) resulted in four factors: 1) supporting personal development, 2) modelling professional development, 3) fostering autonomy, and 4) monitoring performance. The four factors explained 43% of the total variance of item scores. The Cronbach’s alphas for the subscale scores were between .42 and .75.

Conclusions
The MERIT can help mentors reflect on their beliefs and professional knowhow. These reflections can serve as input for the faculty development initiatives mentors undertake, which may ultimately improve their knowledge and skills as a mentor.
Best approximations of the ϕ-Hadamard fractional Volterra integro-differential equation by matrix valued fuzzy control functions
Authors: Rezaei Aderyani Safoura , Saadati Reza 
Published: March 2021

AbstractIn this article, first, we present an example of fuzzy normed space by means of the Mittag-Leffler function. Next, we extend the concept of fuzzy normed space to matrix valued fuzzy normed space and also we introduce a class of matrix valued fuzzy control functions to stabilize a nonlinearϕ-Hadamard fractional Volterra integro-differential equation. In this sense, we investigate the Ulam–Hyers–Rassias stability for this kind of fractional equations in matrix valued fuzzy Banach space. Finally, as an application, we investigate the Ulam–Hyers–Rassias stability using matrix valued fuzzy control function obtained through the Mittag-Leffler function.
The prevalence of depression symptoms among infertile women: a systematic review and meta-analysis
Authors: Kiani Zahra , Simbar Masoumeh , Hajian Sepideh , Zayeri Farid 
Published: March 2021

Abstract
Background
Infertile women’s mental health problems, including depression, are key fertility health issues that affect infertile women more severely than infertile men. Depression may threaten the health of individuals and reduce the quality of their lives. Considering the role and impact of depression on responses to infertility treatments, a systematic review and meta-analysis were conducted to investigate the prevalence of depression symptoms among infertile women.

Methods
International databases (PubMed, Cochrane Library, Web of Sciences, Scopus, Embase, and PsycINFO), national databases (SID and Magiran), and Google Scholar were searched by two independent reviewers for articles published from 2000 to April 5, 2020. The search procedure was performed in both Persian and English using keywords such as “depression,” “disorders,” “infertility,” “prevalence,” and “epidemiology.” The articles were evaluated in terms of their titles, abstracts, and full texts. The reviewers evaluated the quality of the articles using the Newcastle–Ottawa Scale, after which they analyzed the findings using STATA version 14. The I2 and Egger’s tests were performed to examine heterogeneity and publication bias, respectively.

Results
Thirty-two articles were subjected to the meta-analysis, and a random effects model was used in the examination given the heterogeneity of the articles. The samples in the reviewed studies encompassed a total of 9679 infertile women. The lowest and highest pooled prevalence rates were 21.01% (95% confidence interval [CI]: 15.61–34.42), as determined using the Hospital Anxiety and Depression Scale, and 52.21% (95% CI: 43.51–60.91), as ascertained using the Beck Depression Inventory, respectively. The pooled prevalence values of depression among infertile women were 44.32% (95% CI: 35.65–52.99) in low- and middle-income countries and 28.03% (95% CI: 19.61–36.44) in high-income countries.

Conclusion
The prevalence of depression among infertile women was higher than that among the general population of a given country. Especially in low- and middle-income countries, appropriate measures, planning, and policy that target the negative effects of depression on infertile women’s lives should be established to reduce related problems.
The Nonlinear Linkage Between Earnings Homogamy and Earnings Inequality Among Married Couples
Authors: Shen Yifan 
Published: March 2021

Abstract
More married couples today consist of two high-earning or two low-earning partners (i.e., earnings homogamy), which leads to greater earnings inequality in married-couple families. Surprisingly few studies have examined this relationship by earnings level, leaving open the question of whether the increase in earnings homogamy at each level of earnings contributes equally to between-couple earnings inequality. I address this question using data on urban China during 1988–2013. Changes in earnings homogamy account for 6% to 11% of the increase in between-couple inequality, but importantly, decomposition reveals that 57% to 68% of the overall impact is driven by the growing earnings homogamy among the top 20% of husbands and their wives. I reach the same finding by replicating the analyses using data from the United States. Two explanations account for this finding: (1) earnings homogamy has increased more among high earners; and (2) all else being equal, increases among high earners are mechanically more influential in shaping the level of between-couple inequality. These findings have important theoretical and policy implications.

Published: March 2021

The Yogyakarta City Government launched an innovation in health promotion at mosques, named the "healthy inside and outside" in 2015. This program is a partnership with the mosque keeper to promote clean and healthy living habits. No studies have yet evaluated the extent of the success of the program. This study aims to see the effectiveness of the program in changing people's healthy behaviour. This type of research is an analytic survey with a cross-sectional study approach. The research location is in the working area of the Umbulharjo Community Health Center. The population is 4608 families. The number of samples is 108 people who live around the mosque. The inclusion criteria is housewives because they have a lot of time at home, so there are more opportunities to be exposed to Compact Disc (CD) in mosques than other people who work outside the home. The exclusion criteria were people who were unwilling and deaf. The sampling technique is a probability proportionate to size, namely by taking the sample referring to mosques that play CDs and those that do not play with 2: 1 ratio. The control variables are age and level of education. Data were collected through a questionnaire and analyzed by Mann Whitney-test. The results showed a difference in the community's mean knowledge and attitudes around the mosque playing (69.44) and not playing the health promotion CD (60.14). The Mann Whitney-test results obtained a p-value of 0.00, which means there is an effect of CD health promotion playing on the level of public knowledge about PHBS. The playing CD health promotion at mosques in Umbulharjo District, Yogyakarta, has benefited from increasing housewives' knowledge about healthy and clean behaviour.
