Published: May 2020

<p class="Abstract">Understanding that electrical engineering graduates who have experience and are able to know the electric power system in the industry are the main thoughts of the writer to conduct research. Through the manufacture of a three-phase ac motor control practicum module, which is the type of motor most often used in industrial activities, is expected to provide more knowledge to prospective graduates of electrical engineering engineers. The author determines the two previous research categories chosen as references, namely the training of electric motor modules and the final project of electrical engineering students. In this study the ATV12HU15M2 inverter is used to control changing the frequency value as an input variable to determine its effect on output variables such as voltage, current, power, rpm, and THD. Equipped with SoMove software that is connected to the laptop to be able to change the value of input variables such as motor power, number of poles, and power factors to match the specifications of the electric motor used, the software can also monitor if an error occurs in the system. At the measurement stage, the measuring instrument used is a Power Analyzer to measure the input power of a single-phase system at the source grid PLN, the output power of a three-phase electric motor system, and experimental measurements of motors coupled with a dc generator. For the purposes of data processing, DataView software is used to display the measurement results into a laptop, the resulting display can be in the form of a waveform graph, a graph of THD occurrence, and power information for which the displayed data can be stored. The THD result most optimal at 50Hz frequency with THDv value 18.69% and THDi value 9.04%.</p><p class="Keywords"> </p>
Special Issue on Machine Accuracy Evaluation
Authors: Ibaraki Soichi , Archenti Andreas 
Published: May 2020

The accuracy of a three-dimensional (3D) positioning system can ultimately be evaluated via measurement of a 3D vector between command and actual end-effector positions at arbitrary points over the entire workspace. This is a simple, yet challenging, metrological problem. The motion accuracy of a machine tool is traditionally evaluated on an axis-to-axis basis, with every error motion of every axis being independently measured as part of a one-dimensional measurement process in a different setup. Toward the ultimate goal of 3D position measurement over the entire workspace, research efforts have offered several new, practical measurement technologies.
This special issue covers the technical and academic efforts regarding the evaluation of machine tool accuracy. The papers in this special issue clarify the latest research frontiers regarding machine tool accuracy from a metrological viewpoint. In the first paper, by Montavon et al., error calibration technologies and their management are reviewed within the Internet of production concept. Long-term accuracy monitoring and management are clearly among the most crucial technical challenges faced regarding machine tools, and the work by Xing et al. is related to them. Ibaraki et al. presented machining tests to evaluate the thermal distortion of a machine tool. Peukert et al. studied the dynamic interaction between machine tools and their foundations. Various 3D measurement schemes for determining machine error motions have been investigated by many researchers, and some have been implemented in industrial applications. Kenno et al. and Florussen et al. investigated 3D measurement using the R-test for five-axis machines. Miller et al. studied simultaneous measurement of six-degree-of-freedom error motions of a linear axis. Nagao et al. presented an error calibration method for a parallel kinematic machine tool.
The editors appreciate the contributions of all the authors, as well as the work of the reviewers. We are confident that this special issue will further encourage research and engineering work for improving the accuracy and performance of machine tools.

Published: May 2020

Abstract:
The SARS-CoV-2 (severe acute respiratory syndrome-coronavirus 2) was reported in Wuhan, Hubei Province, People’s Republic of China, and, subsequently, in other provinces and regions across the People’s Republic of China and >212 countries. COVID-19, the disease caused by this coronavirus, was declared a worldwide pandemic by the World Health Organization (WHO). The incidence of patients with fracture who are also positive for COVID-19 is on the rise. The diagnosis and management of such patients can be complicated as their clinical characteristics are heterogeneous. Furthermore, a surgical procedure can be particularly challenging given that the use of high-speed devices results in aerosol generation. In this study, we develop and propose globally applicable guidelines to fill this knowledge gap and we identify and propose the necessary protective strategies for medical personnel in an orthopaedic emergency department and in the inpatient wards. We also introduce diagnostic criteria, surgical complication management, and follow-up strategies for infected patients. These guidelines may be helpful to decrease the infection rate of orthopaedic trauma personnel and to provide diagnosis and treatment therapy for patients with fracture and COVID-19.
« The Bishop’s Candlesticks » : une certaine tradition de la réception hollywoodienne des Misérables
Authors: Szabo Fabrice 
Published: May 2020

Lorsqu’il s’agit d’évoquer les adaptations des Misérables, l’énoncé le plus évident et le plus attendu est le suivant : c’est le destin de Jean Valjean. Pourtant il existe une toute première tradition cinématographique dans laquelle Les Misérables, c’est l’histoire des «Chandeliers de l’Evêque». Dans cet article, nous allons essayer de retrouver cette tradition, d’exhumer quelques films-jalons, en commençant par l’une des toutes premières adaptations du roman réalisée par Albert Capellani en 1906 ou encore celle de Lewis Milestone en 1953. L’essentiel de notre analyse se concentrera sur ce film dont l’originalité tient au fait qu’il propose une lecture conservatrice -au sens nord-américain du terme- du roman et qu’il constitue l’avatar le plus tardif de la tradition des «Chandeliers de l’Evêque».
Hidroterapia y actividad física terapéutica en el medio acuático
Authors: Salar Andreu Cristina 
Published: May 2020

El agua es el medio donde el desarrollo evolutivo se ve favorecido desde la edad temprana (Moreno & Borges, 2009; Pansu, 2010; Penik, 2011). Desarrollar la competencia acuática se ha convertido en uno de los objetivos importantes a tratar desde la más tierna infancia, y sus efectos en el organismo desde la infancia hasta la edad adulta han sido demostrados desde hace décadas (Diem, 1978, 1982; Parker & Blanksby, 1997).
Si a estos beneficios se le añade el carácter terapéutico del medio, permite contemplar este recurso dentro de las áreas de la atención temprana, la pediatría, la neurología, las afecciones musculo-esqueléticas, el deporte, el suelo pélvico, etc. y en cualquier área donde la prevención y el tratamiento de la salud pueda ser abordado.

La Organización Mundial de la Salud (OMS, 2002), define el término salud como “el estado completo de bienestar físico, mental y social y no la mera ausencia de enfermedad”. De ahí que afirmar que las prácticas acuáticas son beneficiosas, es confirmar la necesidad de que estas actividades formen parte de las experiencias que todo ser humano debiera tener en su vida, tanto en los procesos de salud como de enfermedad (Diem, Bresges & Hellmich, 1978; Fouace, 1979; Zuoziené, Akelyté & Zuoza, 2014)...
Bioinformatic screening for candidate biomarkers and their prognostic values in endometrial cancer
Authors: Li Yaowei , Li Li 
Published: May 2020

Abstract

Background:Endometrial cancer is a common gynecological cancer with annually increasing incidence worldwide. However, the biomarkers that provide prognosis and progression for this disease remain elusive.Methods:We analysed endometrial cancers mRNA and miRNA expression data from Gene Expression Omnibus, and searched for differentially expressed candidates, and subsequently validated them with the data from the Cancer Genome Atlas. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using the Database for Annotation, Visualization and Integrated Discovery (DAVID). A protein-protein interaction network was constructed by STRING and visualized using Cytoscape. The prognostic values of the identified hub genes were measured with OncoLnc. In addition, miRecords was used to predict target genes of differentially expressed miRNAs, and finally a miRNA-mRNA regulatory network was constructed.Results:Two eligible human endometrial cancer datasets (GSE17025 and GSE25405) were selected for the study. A total of 520 differentially expressed mRNAs and 30 differentially expressed miRNAs were identified. These mRNAs were mainly enriched in cell cycle, skeletal system development, vasculature development, oocyte maturation, and oocyte meiosis signalling pathways. A total of 160 pairs of differentially expressed miRNAs and mRNAs, including 22 differentially expressed miRNAs and 71 overlapping differentially expressed mRNAs, were validated in endometrial cancer samples using starBase v2.0 project. The prognosis analysis revealed that Cyclin E1 (CCNE1, one of the 82 hub genes, which correlated with hsa-miR-195 and hsa-miR-424) was significantly linked to a worse overall survival in endometrial cancer patients.Conclusions:The hub genes and differentially expressed miRNAs identified in this study might be used as prognostic biomarkers for endometrial cancer and molecular targets for its treatment.

The effect of treatment with a non-invasive foot worn biomechanical device on subjective and objective measures in patients with knee osteoarthritis- A retrospective analysis on a UK population
Authors: Miles Christopher , Greene Andrew 
Published: May 2020

Abstract
Background: Osteoarthritis is a major cause of pain and disability worldwide, therefore ways of treating this condition are paramount to a successful health system. The purpose of the study was to investigate the changes in spatial-temporal gait parameters and clinical measurements following treatment with a non-invasive foot-worn biomechanical device on patients with knee osteoarthritis within the UK. Methods: A retrospective analysis was carried out on 455 patients with knee osteoarthritis. All patients were evaluated using a computerized gait test and two self-assessment questionnaires (WOMAC and SF-36) at baseline and after 3 and 6 months of treatment. The biomechanical device is a shoe-like device with convex pods under the sole that have the capability of changing foot centre of pressure and training neuromuscular control. The device was individually calibrated for each patient to minimise symptoms whilst walking and train neuromuscular control. Patients used the device for short periods during activities of daily living. Repeated measures statistical analyses were performed to compare differences over time.Results: After 6 months of treatment significant improvements were seen in all gait parameters (p<0.01). Specifically, gait velocity, step length and single limb support of the more symptomatic knee improved by 13%, 7.8% and 3%, respectively. These were supported by significant improvements in pain, function and quality of life (48.6%, 45.7% and 22% respectively; p<0.001). A sub-group analysis revealed no baseline differences between those who were recommended joint replacement and those who were not. Both groups improved significantly over time (p<0.05 for all).Conclusions: Our results suggest that the personalised biomechanical treatment can improve gait patterns, pain, function and quality of life. It may provide an additional solution to managing UK patients suffering from knee osteoarthritis but needs to be tested in a controlled setting first.

Published: May 2020

Abstract
Background

It is important to use renewable resources to minimize the environmental risks and the composting is one of the most sustainable methods for the management of organic waste.
Methods

The objective of this work was to evaluate the physicochemical dynamics of microorganisms and to study cultivable microorganisms during the composting process of organic residues in a new model of bioreactor. The formulation of a possible cocktail of microorganisms selected for use as a compound accelerator will be further investigated. In addition, the use of two inoculants (non-commercial inoculum (NCI)) and commercial inoculum (CI)) and a control without inoculant during the composting process will be analyzed to evaluate its efficiency. Composting was performed by mixing organic waste from the garden waste and University Restaurant, obtaining an ideal C/N ratio of 30:1. The composting process was carried out in 1 m3 composters with controlled temperature and aeration.
Results

The thermophilic phase for all treatments was reached by the second day. Mature compost was obtained after an average of 120 days and composting in all treatments showed an increase in the availability of P and micronutrients. During composting, the population of bacteria and actinobacteria were higher than those of yeasts and filamentous fungi.
Conclusions

Increased composting efficiency was observed when starter cultures were used, the treatments presented advantages such as greater mineralization of P-available and micronutrients as Mn and Zn, in terms of the quality of the final product in comparison to the control treatment.
The Doctor’s Heart: A Qualitative Study Exploring Physicians’ Views on Their Professional Performance in Light of Excellence, Humanistic Practice and Accountability

Published: May 2020

Abstract
Background In a field as high-stakes as health care, professional values have long been recognized as an essential mediating force for good medical practice. In the current era of changing market forces, anchoring these values in the professional performance of daily practice can be challenging. In this study we explored how physicians reflect upon their own professional performance and whether they feel they are performing to their best ability in light of excellence, humanistic practice and accountability. Methods We conducted a thematic analysis of written reflections from 786 hospital-based physicians, representing 35 specialties and 18 hospitals. Results When reflecting on their professional performance, physicians differentiated between (i) their calling for being a doctor, (ii) the translation of this calling into daily practice, and (iii) threats to their performance. Reflecting on humanistic practice triggered thoughts about the essence of being a physician in terms of calling, meaning and purpose. Physicians described concrete actions regarding pursuit of excellence and accountability. Furthermore, they suggested that their ability to perform optimally was put under pressure, mainly by heavy workloads and collaboration issues. This pressure negatively affected their calling for being a doctor and hampered the ability to be a humanistic practitioner. Conclusions In this large inventory of reflections, humanistic practice was recognized as the core value of being a physician. However, physicians feel high performance and the ability to act as a humanistic practitioner is hindered by heavy workloads and collaboration issues. Decreasing the clinical burden and reinforcing humanistic and relational aspects of care could foster an environment where physicians can perform optimally.

Abstract
Background: The morbidity of infectious spondylitis is increasing year by year in the elderly. Due to difficulties in coping with open surgery, we aim at presenting a treatment method for infectious spinal inflammation by the combination of Percutaneous Endoscopic Discectomy and Drainage (PEDD) and Percutaneous Pedicle Screw Fixation (PPSF) which obtained satisfactory outcomes in this study.Method: We have retrospectively analyzed 33 patients who had suffered from lumbar infectious spondylitis and undergone PEDD combined with the PPSF treatment. Biopsy specimen was taken from each of them during their operation and the specimen was submitted without delay for microculture. The dynamic change of patient clinical symptoms and their satisfaction degree were assessed by careful physical examination, regular serologic test, imaging study, Odom’s criteria, Frankel score, and visual analog scale (VAS).Result: Among the 33 patients, 22 (66.7%) had excellent symptom relief and the remaining 11 (33.3%) had good symptom relief after PEDD treatment according to Odom’s criteria. Additionally, PPSF was performed on 5 patients in the second stage, and yielded satisfactory result. There were no severe surgery-related complications. The microculture from 24 patients（72.7%）obtained from the operation were positive.Conclusion: PEDD and PPSF were under the influence of local anesthesia, which had lower requirements of patients’ general condition comparing to the traditional open surgery. In addition, PEDD obtained higher positive rate of microorganisms cultured comparing to other minimally invasive methods. PPSF was performed at the second stage to alleviate pain and further improve vertebral stability.
Accuracy of acetabular cup implantation, as a function of body mass index and soft-tissue thickness, with a mechanical intraoperative support device: A retrospective observational study
Authors: Suzuki Hayato , Imai Norio , Hirano Yuki , Endo Naoto 
Published: May 2020

Abstract
Background

HipCOMPASS, a mechanical intraoperative support device used in total hip arthroplasty (THA), improves the cup-alignment accuracy. However, alignment accuracy in obese patients has not been examined. We aimed to compare the cup-alignment accuracy, using HipCOMPASS, between patients with and without obesity.
Methods

We retrospectively evaluated 448 consecutive patients who underwent primary THA using HipCOMPASS. We measured the soft-tissue thickness of the anterior-superior iliac spine (ASIS) and pubic symphysis using preoperative computed tomography (CT) images and the difference in cup angle pre- and postoperatively based on the cup-alignment error on CT. We used Pearson coefficients to determine the correlation of body mass index (BMI) and soft-tissue thickness with cup-alignment error. We created receiver operating characteristic (ROC) curves to determine the cutoff value for statistically significant cup-alignment error factors in radiographic inclination and anteversion of ≥ 5°.
Results

There were significant correlations between the absolute value of radiographic anteversion difference and BMI (r = 0.205), ASIS thickness (r = 0.419), and pubic symphysis thickness (r = 0.434). The absolute value of radiographic inclination difference was significantly correlated with ASIS (r = 0.257) and pubic symphysis thickness (r = 0.202). The ROC curve showed a pubic symphysis thickness of 37.2 mm for a ≥ 5° implantation error in both radiographic inclination and anteversion simultaneously. The cup-alignment error for HipCOMPASS was large in patients whose pubic symphysis thickness was ≥ 37.2 mm on preoperative CT.
Conclusion

We recommend using methods other than HipCOMPASS, including computed tomography-based navigation systems, in obese patients.
A novel technique of treating anterior cruciate ligament injury: combining the ACL reconstruction and repair.
Authors: Yang Yuan , Chen Kang , Feng Wenzhe , Zhu Weimin , Lai Yuxiao 
Published: May 2020

Abstract
Background

To illustrate a novel technique of treating anterior cruciate ligament injury.
Methods

If the ACL stump is strong enough and of good quality, we combine the ACL reconstruction and repair together.
Results

It is assumed that this will be better for the knee biomechanics in contrast to the simple reconstruction. This technique may also save the graft. That means we can only harvest one tendon gracilis or semitendinosus to satisfy the need of the knee stability.
Conclusions

This technique of combining the reconstruction and repair protects the knee proprioceptive feelings, accelerate the revascularization and strengthen the reconstructed ACL. This technique may also save the ligament graft and avoid the complications of the donor site. We are looking forward to comparing the outcomes of this technique to the outcomes of simple ACL reconstruction.

Published: May 2020

Abstract
Background

To analyze the effects of the administration of febuxostat, a selective xanthine oxidase (XO) inhibitor, on both in vitro and in vivo models of the waste of skeletal muscles, due to LM8 osteosarcoma cells.
Methods

C2C12 myotubes were incubated in the conditioned medium of LM8 osteosarcoma cells. At the same time, febuxostat was added at a concentration of 3 µM and 30 µM, and reactive oxygen species(ROS) was measured using 2’,7’-dichlorofluorescein diacetate (DCF-DA) at 2 h and 24 h after exposure. Furthermore, an in vivo study was performed on male C3H mice (5 weeks old) that were subcutaneously injected with LM8 osteosarcoma cells on their backs. Febuxostat was administrated in the drinking water at a concentration of 5 µg/ml (group F5), and 25 µg/ml (group F25). In addition, tumor-bearing mice without febuxostat (group TB) and control mice (group C) were established. At 4 weeks after the inoculation of tumor cells, body weight, wet weights of the gastrocnemius muscles, XO activity, 8-hydroxy-2’-deoxyguanosine(8-OHdG), and expression of TNF-α and IL-6 were evaluated and compared among the 4 groups.
Results

ROS generation was clearly observed in C2C12 myotubes following incubation in the conditioned medium of LM8 osteosarcoma cells. ROS generation was significantly inhibited by febuxostat administration. Furthermore, LM8-bearing mice showed significant loss of body weight and wet weight of the gastrocnemius muscles, in which XO activity, 8-OHdG, and expression of IL-6 were significantly increased compared to those in mice without injections of the tumor cells. Further, febuxostat administration not only significantly improved the body weight and wet weight of the skeletal muscles, but also reduced markers of oxidative stress and expression of pro-inflammatory cytokines. Febuxostat did not show anti-tumor effects, including inhibition of lung metastasis and improved overall survival.
Conclusion

Febuxostat, which is clinically used for treatment of hyperuricemia, is effective against the waste of the skeletal muscles induced by LM8 osteosarcoma cells.
