Nutzung von Standortrollen für die Fabrikkonzeptplanung
Authors: Berchtold Marc-André , Böhm Markus , Erlach Klaus , Bauernhansl Thomas 
Published: September 2021

Abstract
Bisher verwenden Fabrikplanungsansätze im frühen strategischen Planungsabschnitt oft sogenannte Fabriktypen. Diese Fabriktypen verfolgen jedoch nicht ein ganzheitliches Zielsystem, sondern fokussieren jeweils auf einzelne Ziele. Darüber hinaus ermöglichen die Fabriktypen nur eine isolierte Betrachtung der Einzelfabriken, weshalb deren Planung in Produktionsnetzwerken nicht mit Blick auf das Gesamtsystem erfolgt. Für Fabrikplanungen in Netzwerken sind gerade die Relationen zwischen den Fabriken relevant, was in den Fabriktypen nicht abgebildet ist. Die Perspektive „Standortrolle“ kann helfen, diese Lücke zu schließen.

Attention emotion recognition via ECG signals
Authors: Mao Aihua , Du Zihui , Lu Dayu , Luo Jie 
Published: September 2021

BackgroundPhysiological signal‐based research has been a hot topic in affective computing. Previous works mainly focus on some strong, short‐lived emotions ( e.g., joy, anger), while the attention, which is a weak and long‐lasting emotion, receives less attraction. In this paper, we present a study of attention recognition based on electrocardiogram (ECG) signals, which contain a wealth of information related to emotions.MethodsThe ECG dataset is derived from 10 subjects and specialized for attention detection. To relieve the impact of noise of baseline wondering and power‐line interference, we apply wavelet threshold denoising as preprocessing and extract rich features by pan‐tompkins and wavelet decomposition algorithms. To improve the generalized ability, we tested the performance of a variety of combinations of different feature selection algorithms and classifiers.ResultsExperiments show that the combination of generic algorithm and random forest achieve the highest correct classification rate (CCR) of 86.3%.ConclusionThis study indicates the feasibility and bright future of ECG‐based attention research.
Building a Bridge for Batten Disease
Authors: Feuerborn Melissa , Keirns Carla , Barohn Richard 
Published: September 2021

Background. Neuronal Ceroid Lipofuscinosis, or Batten disease, is a neurodegenerative disorder that results in seizures, vision loss, vegetative state, and premature death. This project aims to understand the value of disease organizations in the management of Batten disease progression.
Methods. Seven semi-structured interviews with caregivers of children with Batten disease were conducted at a national family conference. Also, five semi-structured telephone interviews with disease organizations were conducted, two of which were Batten disease specific.
Results. Most caregiver participants reported difficulties in getting a diagnosis. All participants reported significant benefit from involvement in the Batten Disease Support and Research Association (BDSRA) and associated family conference. Some of the most challenging aspects of care centered around a lack of in-home aid, medical equipment, and the education system. The disease advocacy organizations included Rare KC, the National Organization for Rare Disorders (NORD), Global Genes, Noah’s Hope, and Taylor’s Tale. Disease organizations encourage rare disease families to thrive by providing the bridge that connects patients, physicians, and researchers. A central organization implements an avenue for individuals to share information and meet people in the rare disease community.
Conclusions. The participants provided clear examples of the benefits families received from being involved in a rare disease organization.
Teleseismic waveform modeling including geometrical effects of superficial geological structures near to seismic sources
Authors: Gaffet Stéphane 
Published: September 2021

AbstractWe analyze observed seismograms of 21 events recorded at teleseismic distances in France from nuclear explosions detonated at Nevada Test Site (NTS). Variations of the displacement waveform, duration, and amplitude are studied in terms of influence of the explosion's source medium and location in the laterally heterogeneous Yucca Flat basin. The analysis is made using numerical modeling of data that simulate the modifications of the original source signal by the geometry of the surrounding geological structure. Spalling and nonlinear effects are not included in computations. The numerical simulations of the variations are processed using a mixed symbolic and numerical algorithm developed to simulate the ground motions that may be recorded in any kind of two-dimensional heterogeneous nonvertical structures. This algorithm is linked (1) to the discrete wavenumber-boundary integral equation method and to the reciprocity theorem to simulate the displacement field radiated to far-field distances by the source site geological structure, and (2) to ray propagation to propagate the displacement field across the mantle from the source region to the receiver. Variations of the computed displacement amplitudes are as large as a factor of 2 from one detonation point to another. The shapes of the observed seismograms are modeled with good reliability for most of the 21 events in the frequency band studied, i.e., 0.2 to 2.5 Hz. A set of 21 relative yield estimates are derived, which include the source site response and thus the amplitude variations induced by the heterogeneous structure of the source region.
Seismogram synthesis for multi-layered media with irregular interfaces by global generalized reflection/transmission matrices method. II. Applications for 2D SH case
Authors: Chen Xiaofei 
Published: September 2021

AbstractAs the second part of a series study attempting to present a new method of seismogram synthesis for the irregular multi-layered media problems, the present article is devoted to discussing the aspects of the implementation of our new formulation developed earlier in part I of this series study (Chen, 1990). In this article, we have verified the validity of the formulation by comparing our numerical results with the existing analytical solutions for the scattering problem of a semi-circular canyon, and have shown its applicability by computing the synthetic seismograms for several selected irregular multi-layered media cases. Finally, applying our algorithm to the Whittier-Narrows earthquake of 1987, we have successfully interpreted the observed records.

Published: September 2021

Propolis is one of the natural products produced by kelulut bees and is still not widely used. The type of stingless bee that is the prima donna in the community is Heterotrigona itama. This study aims to determine the phytochemical content of the n-hexane fraction of Heterotrigona itama bee propolis collected from Kutai Kartanegara, East Kalimantan. The n-hexane fraction was obtained from the methanol extract of H. itama propolis by the liquid-liquid partition method. After obtaining the n-hexane fraction, the research continued with a qualitative phytochemical test to identify the compound and determine total phenolic. Antibacterial activity was determined by the agar well diffusion method with a serial concentration in Escherichia coli bacteria. Qualitative phytochemical analysis in the form of color changes showed that the n-hexane fraction of H. itama propolis contained flavonoids, alkaloids, saponins, and tannins. Based on the results, the total phenolic content of the n-hexane fraction sample was 490 mgGAE/100 g. It caused the n-hexane fraction to have lower phenolic content than the methanol extract (792 mg GAE100 g). Furthermore, this result indicated that the non-polar fraction was not substantial enough to extracted phenolic compounds. It correlated to the antibacterial activity of the n-hexane fraction, which was very weak (2 mm ± 1.5) at 200µg/mL concentration.

Road traffic accidents are regarded as the most common non communicable epidemics of the world. They are also a major cause for morbidity and mortality. The most common and vulnerable part of the body which is affected during road accidents is the head. This study was done at KIMS hospital Bangalore with an aim to observe the range of cranio-cerebral injuries by analysing the postmortem records between January 2011 to December 2012 retrospectively, which would provide valuable data for implementing effective emergency services to reduce trauma related mortality. During the 2-year study period the study population had a total of 143 decedents ranging between age 5 years to 84 years. Victims of both sexes comprised the study population. The spectrum of head injuries with respect to incidence of skull fractures and type of intracranial haemorrhage were noted. Male predominance was seen over females in 83% of cases. The most common age group to be affected was between 21-30 years, who made 30% of study population. 52% of the decedents had skull fractures, of which 50% of them had sub-arachnoid haemorrhage followed by 47% of decedents with sub-dural hemorrhage. Pedestrians accounted to 38% of the decedents while the remainder 62% accounted for vehicular occupants.

Authors: Lomi Mosmi , Daniel M Jonathan 
Published: September 2021

Determining gender is one of the most important procedure in forensics. Teeth are made of the most enduring mineralized tissues in the body, as such, they have an extraordinary resistance to putrefaction and the effects of external agents (physical, thermal, mechanical, chemical or biological) which makes them invaluable material for anthropological, genetic, odontologic and forensic examinations.i)To assess the degree of sexual dimorphism in maxillary canine using maxillary canine index, maxillary first molar and central incisor using mesiodistal (MD) and buccolingual/buccopalatal (BL) dimensions of the crown. ii) To determine the accuracy of maxillary canine index, first molar and central incisor dimensions (mesiodistal and buccolingual/buccopalatal) in determining sex.This study consisted of total 30 participants (males=15, females=15) of age group ranging from 20 to 35 yrs. Measurement of dimensions of selected teeth were performed on maxillary cast using digital Vernier caliper, resolution 0.01mm. Data thus obtained were analyzed statistically.The mean values of all the measurements in males were greater than females. There was statistical significant difference in mean value of bucco-lingual width of molar, mesiodistal width of canine (on left side, right side and average) and the inter-canine distance between males and females. The buccolingual width of molar showed the highest % of sexual dimorphism (5.33%) and the mesiodistal width of molar showed the least % of dimorphism (0.7%). Bucco-lingual width of molar posed the highest prediction accuracy for gender determination. We conclude that buccolingual width of maxillary first molar can be used to predict the gender when only teeth of maxillary arch are available for forensic examination.

Published: September 2021

Road traffic accidents have become a major public health issue causing fatality and disabilities affecting and impacting the socio-economic development, an examination of the profiles of two-wheeler road traffic accidental injuries and a detailed forensic analysis is needed to reduce fatality and life altering disabilities. In our present study done during a study period of 5 years from 2015 to 2019 the total number of autopsies reported to the mortuary was 930 cases, of which 233 deaths were due to two wheeler accidents. Male victims predominated (217) amounting to 93.1% when compared with female victims in a ratio of 13.5 : 1 and 70.0% (163) of the victims were from rural areas. The cause of death in majority of cases was head injury in 157 (67.4%) cases. Fatal injuries were confined to a single region in 168 (72.1%) cases and to multiple regions in 65 (27.9%) cases. Skull fractures were noted in 148 cases with 70 cases of fissure fracture on calvaria alone and 30 cases of comminuted fracture. Haemorrhages were predominantly of subdural type in 160 cases, and subarachnoid type in 152 cases. About, 56.7% victims died in collision with 4 wheelers, 13.3% in collision with two wheelers, 15.0% due to collision with pedestrian, 2.1% victims died due to collision with 3 wheelers. Driver clothes with fluorescent marks, day-time running lights for two wheelers and helmets in white or mild colors are suggested for easy noticability and to prevent collisions.

Background: To investigate the protective effects of vitamin E and methylprednisolone on ischemia and reperfusion testicular injury after testicular torsion and detorsion in West African dwarf (WAD) goats. Methods: Thirty-two male WAD goats were randomly allocated into four groups (n=8); group A was treated with vitamin E, group B with methylprednisolone, group C with combo-therapy of vitamin E and methylprednisolone and group D was the control. The levels of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), total tissue protein (TTP) and catalase (CAT) were assayed while tissue biopsies were harvested for evaluation of degeneration of germinal cells, desquamation in germinal cells, interstitial edema and haemorrhage. Result: Findings revealed that Vitamin E administered immediately post ligature application significantly (p less than 0.05) decreased MDA level in groups A and C. Vitamin E monotherapy and its combination with methylprednisolone respectively ameliorated more the cellular damage and histological alterations caused by ischaemia and reperfusion injury. This study, therefor, suggests that vitamin E monotherapy and its combination with methylprednisolone is more beneficial in the management of short and long term ischemia/reperfusion injury respectively.

Higher-order thinking skills (HOTS) are needed to determine the student's ability to construct an answer. In this study, researchers analyzed the higher-order thinking skills of students of the Mathematics Education Study Program in constructing one of the test answers, namely constructing a binary representation of real numbers in the Introduction to Real Analysis course. Fifty-two students taking the Introduction to Real Analysis course in the odd semester 2020/2021 are the subjects of this research. Data was collected using a test that was analyzed based on the indicator of higher-order thinking ability created (C6). It was revealed that the students' higher-order thinking skills were in the sufficient category. This means that most students have not been able to construct and analyze information into the right strategy. The results of this study are expected to be a reference for the lecture process where students are familiarized with giving HOTS-oriented questions during exams and practice questions for lectures to help develop higher-order thinking skills.Keywords: Bloom's taxonomy-C6; higher order thinking skill; binary representation Kemampuan berpikir tingkat tinggi diperlukan untuk mengetahui kemampuan mahasiswa mengkonstruksi suatu jawaban.
