Pour une éducation sensorielle à travers les activités physiques : analyse de pratique et pistes professionnelles
Authors: Paintendre Aline , Schirrer Mary , Sève Carole 
Published: February 2020

Cet article présente une analyse de l’activité de lycéens en step. En référence au cadre du cours d’action (Theureau, 2006), il décrit les apprentissages sensoriels de lycéens débutants en step, et plus précisément la manière dont ils apprennent à être attentifs à leurs sensations corporelles et à les interpréter. L’enjeu est de mieux comprendre les processus de construction de « savoir-faire perceptifs » chez les pratiquants, en nous référant à leur vécu. En effet, la construction de compétences perceptives et sensibles apparaît fondamentale chez le pratiquant pour réguler les actions motrices, apprendre à gérer l’effort, mais aussi dans une logique de développement du bien-être et de la santé. Aussi, il s’agit d’explorer le développement de savoir-faire perceptifs, afin de proposer des stratégies d’intervention et des postures d’accompagnement singulières pour des acteurs de l’éducation par les APSA.

Published: February 2020

Cette étude s’intéresse à l’expérience d’arbitrage d’élèves dans des leçons d’EPS. Centrée sur des données d’expérience vécue, cette étude les enrichit avec des données relatives à la motivation des élèves dans le but de mettre à jour leurs stratégies pour occuper le rôle d’arbitre et expérimenter la responsabilité inhérente à ce rôle. Les données d’expérience ont été recueillies et traitées dans le cadre théorique et méthodologique du cours d’action (Theureau, 2004, 2006). Les données motivationnelles ont été recueillies et traitées dans le cadre théorique de la motivation auto-déterminée (Deci & Ryan, 2002). Les résultats font apparaitre (1) trois préoccupations typiques (tenir le rôle d’arbitre, s’aider des autres, se délester du rôle d’arbitre), et (2) des formes d’amotivation, de régulation externe et de motivation intrinsèque à la connaissance et à l’accomplissement, ainsi qu’un besoin d’autonomie plus faible que ceux de compétence et d’affiliation. Sur cette base sont (1) discutés le repérage de stratégies d’alternance entre ces préoccupations typiques caractérisant chez les élèves leur façon d’assumer des responsabilités, et (2) proposées des aides à l’intervention pour concevoir des environnements encourageant les élèves à occuper le rôle d’arbitre à partir de gestalts.
Traits of sub-kilometre F-region irregularities as seen with the Swarm satellites
Authors: Aol Sharon , Buchert Stephan , Jurua Edward 
Published: February 2020

Abstract. During the night, in the F-region, equatorial ionospheric irregularities manifest as plasma depletions observed by satellites, and they may cause radio signals to fluctuate. In this study, the distribution characteristics of ionospheric F-region irregularities in the low latitudes were investigated using 16 Hz electron density observations made by a faceplate which is a component of the electric field instrument (EFI) onboard Swarm satellites of the European Space Agency (ESA). The study covers the period from October 2014 to October 2018 when the 16 Hz electron density data were available. For comparison, both the absolute (dNe) and relative (dNe∕Ne) density perturbations were used to quantify the level of ionospheric irregularities. The two methods generally reproduced the local-time (LT), seasonal and longitudinal distribution of equatorial ionospheric irregularities as shown in earlier studies, demonstrating the ability of Swarm 16 Hz electron density data. A difference between the two methods was observed based on the latitudinal distribution of ionospheric irregularities where (dNe) showed a symmetrical distribution about the magnetic equator, while dNe∕Ne showed a magnetic-equator-centred Gaussian distribution. High values of dNe and dNe∕Ne were observed in spatial bins with steep gradients of electron density from a longitudinal and seasonal perspective. The response of ionospheric irregularities to geomagnetic and solar activities was also investigated using Kp index and solar radio flux index (F10.7), respectively. The reliance of dNe∕Ne on solar and magnetic activity showed little distinction in the correlation between equatorial and off-equatorial latitudes, whereas dNe showed significant differences. With regard to seasonal and longitudinal distribution, high dNe and dNe∕Ne values were often found during quiet magnetic periods compared to magnetically disturbed periods. The dNe increased approximately linearly from low to moderate solar activity. Using the high-resolution faceplate data, we were able to identify ionospheric irregularities on the scale of only a few hundred of metres.

Introduction:
Analysis of the Fundamentals of Arthroscopy Surgery Training (FAST) workstation regarding increased proficiency and retention of basic arthroscopy skills in novice subjects.

Methods:
First-year medical students from a single allopathic medical school performed weekly standardized FAST workstation modules for a consecutive 6 weeks. Primary outcomes evaluated were time to task completion and error rate on specific modules. Scores were analyzed using a one-way repeated measures analysis of variance design for overall trends in time and errors over the 6-week study. Psychomotor retention was analyzed after a 12-week and 24-week interlude.

Results:
Across the initial 6-week study, the average time to complete all modules at the workstation decreased significantly (P < 0.001) with a mean reduction in the total workstation time of 21.9 minutes (s = 8.12 minutes). Weekly comparisons showed the most significant improvement from week 1 to week 2 for the total workstation time (P < 0.001). Results after a 12-week and 24-week interval of inactivity demonstrated no significant difference in the mean workstation time or errors when compared with the original 6-week study.

Discussion:
The FAST workstation significantly improved the task performance of novice participants over a 6-week period with no significant deterioration in task performance after 12 and 24 weeks of inactivity.

In addition, the author’s original method for evaluating Health-Related Fitness components was presented.
Main findings. The pedagogical experiment was carried out during physical education classes with an experimental group comprising boys, using a continuous run for 40 lesson units as a warm-up in the form of running games and a control group performing standard tasks introducing the exercises. In the children from the control group, during the first and last classes of the experiment, during the run, the SPORT TESTER measured cardiovascular response. Experiment effectiveness was assessed based on the results of the analysis of heart rate stabilisation and the results of the 1,000-m run. It was proposed to evaluate the value of the 1-000-m run results compared to other Health-Related Fitness components, using the uni year scoring scale created by the author.
Results. During the final stage of the experiment, the process of stabilising exercise heart rate was found in boys from the experimental group, indicating muscle metabolism processes at the oxygen threshold level typical for jogging. All participants of the experiment completed the Punctual train 1,000-m race with a better result than before the experiment.
Conclusions.
1.	The conducted experiment allowed to achieve positive results in the scope of improving economy of continuous running. Ten-year-old children in the second exam, without signs of greater fatigue, covered a distance of 1,000 m.
2.	The proposed fun and game forms can be successfully used to teach continuous runs and serve as a standard and objective tool for assessing endurance.
3.	The uni year scoring scale can help students in self-assessment of Health-Related Fitness.
A Practical Method for Detecting Fluff Quality of Fabric Surface Using Optimal Sensing
Authors: Jin Shoufeng , Lin Qiangqiang , Bie Yu , Ma Qiurui , Li Zhixiong 
Published: February 2020

The raising process has been widely used in manufacturing fabric productions. After raising the surface of the fabric, productions are covered with a fluff layer. The quality of the fabric surface is often valuated by the fluffing type. In order to objectively assess the fluff quality of the fabric surface, an optimal sensing method is proposed in this paper. The fluff contour image was firstly collected by the light-cut imaging device. Then, the fluff region was segmented by the adaptive image segmentation method, the contour coordinates of the fabric were extracted using the freeman chain code and constructed in the form of the binary image. Lastly, a back-propagation neural network (BPNN) was used to learn the relationship between the contour coordinates and the fluff quality. On this basis, a practical fabric fluff detection platform was developed based on the optimal sensing technique. Experimental tests were conducted to evaluate the performance of the proposed method in detecting the fluff quality with four different colours and different fluffing processes. Furthermore, the actual fabric inspection was carried out. The detection correct rate can reach 94.17 %, which can meet the practical production requirement.

Published: February 2020

Aims: To assess the aquaculture potential of endogenous species in their habitat for domestication and preservation.
Study Design: Growth performances of fish caught was analyzed by family, species, sex and month.
Place and Duration: This study was conducted from April 12 to June 28, 2016 at CREVS (Cameroon Reptiles and Ecosystems Valorization Society) located in the District of Yabassi, Department of Nkam, Coastal Region of Cameroon.
Methodology: A total of 160 fishes were collected by quantitative sampling for 3 months in the Nkam River.
Results: It appears that two families of fish were recorded: the Cyprinidae (Labeo sanagaensis) and the Cichlidae (Tilapia cameronensis, Sarotherodon galilaeus sanagaensis, Sarotherodon nigripinnis dolloi, Tylochromis sudanensis, Hemichromis elongatus, Tylochromis trewavasae and Chromidotilapia gutheri gutheri). L. sanagaensis recorded the highest relative abundance (30%) against 3.13% (C. gutheri gutheri). Large fish were recorded in the majority of species in males, except in T. trewavasae and H. elongatus. The average total length was 23.71 ± 8.31 cm and the average total weight was 266.11 ± 200.96 g. Size frequency distribution of fish was bimodal with a large mode at size 20 cm and a small at size 36 cm. Small fish were abundant in catches especially in S. nigripinnis dolloi and C. gutheri gutheri. The allometric coefficient b of the weight-length relationship averaged 3.01 ± 0.87. The fish presented three types of growth: isometric, positive and negative allometric, and the condition factor K was greater than 1.
Conclusion: It was concluded that these fish species could in general be potential candidates for domestication.

The basic objectives of the study were to enquire in to the involvement of various types of costs, the returns per rupee invested and the benefit thereof in different agro-ecosystems in the state of Jammu and Kashmir in general and valley of Kashmir in particular, especially the sampled districts. This study was based upon primary and secondary data. A multi-stage random sampling was utilised for collection of date from 432 respondents of four different agro-ecological zones. For major crops, the cost of cultivation were estimated by concept utilised by Commission on Agricultural Costs and Prices (CACP), Government of India. The results revealed that fruit crop agro-ecosystem is highly remunerative than field crop and crop agro-ecosystems, though the fruit crop involve huge of investment in terms of different costs. The livestock based agro-ecosystem is also dominant in some parts of the Kashmir region with declining trend. The results revealed that the gross returns of paddy and apple, livestock and cash crop were Rs. 23250, Rs. 321000, Rs. 108920 and 106915 respectively. This study had its applicability in the daily routine life of any household dwelling in the sampled agro-ecosystems. The study could be of utmost importance in selecting the crop in which the region/agro-ecosystem had specialisation or absolute advantage.

Published: February 2020

AbstractA sodium thermal electrochemical converter (Na‐TEC) generates electricity directly from heat through isothermal expansion of sodium ions across a beta″‐alumina solid‐electrolyte. This heat engine has been considered for use with conventional concentrating solar power (CSP) systems before. However, unlike previous single‐stage devices, the improved design uses two stages with an interstage reheat, allowing more economical and efficient conversion up to 29% at a hot side temperature of 850 °C. Herein, a cost‐performance analysis for this improved design assesses opportunities for distributed‐CSP in the context of micro‐combined heat and power systems. A high‐level techno‐economic analysis (TEA) is presented that explores four scenarios where a Na‐TEC is used as the heat engine for a distributed‐CSP system. Overnight capital cost and levelized cost of electricity (LCOE) are estimated for a system lifetime of 30 years, revealing that overnight capital costs in a range from $3.57 to $17.71 per We are feasible, which equate to LCOEs from 6.9 to 17.2 cents kWhe−1. This analysis makes a significant contribution by concurrently quantifying the efficiency and unit costs for a range of multistage configurations, and demonstrating that a Na‐TEC may be a promising alternative to Stirling engines for distributed‐CSP systems at residential scale of 1–5 kWe.

Published: February 2020

AbstractEdamame, or vegetable soybean, has gained popularity in the United States, likely due to its nutritional quality, purported human health benefits, and flavor. Little information is available about the performance of current edamame cultivars in Florida areas. The objective of this study was to evaluate yield and production potential of edamame genotypes in northern Florida. Nineteen genotypes (based on preliminary study) were selected and planted at two locations (Jay and Citra) to evaluate phenotypic performance, including emergence, plant height, nodes per plant, 100‐green seed weight, fresh pod yield, percentage of 1‐, 2‐, and 3‐seeded pods, total lipid concentration, and total protein content. Genotypes and locations showed a significant effect on most of the traits studied. Edamame grown at Jay produced significantly higher yield and 100‐green seed weight than the plants grown at Citra. Two early maturing genotypes (PI614832 and PI584470) and one late maturing genotype (PI633424) showed high yield potential, >30 g of 100‐green seed weight, and high protein content at Jay. In addition, PI417206 showed the highest 100‐green seed weight across locations (50.81 g) and demonstrated moderate yield potential with high protein content and low lipid concentration and may be a suitable candidate for cultivation in different areas in Florida after further evaluation. Number of pods per plant and 100‐green seed weight significantly correlated with pod yield, could be considered as selection tool for edamame yield under Florida growing conditions. This study has established a basic knowledge on edamame production for Florida growers and selected lines suitable for the region.
Essential Updates 2018/2019: Essential Updates for esophageal cancer surgery
Authors: Seto Yasuyuki 
Published: February 2020

AbstractKey papers to treatment of esophageal cancer surgery and reduction of postoperative complications after esophagectomy published between 2018 and 2019 were reviewed. Within this review there was a focus on minimally invasive esophagectomy (MIE), robot‐assisted MIE (RAMIE), and centralization to high‐volume center. Advantages of MIE, irrespectively of hybrid or total MIE, to prevent postoperative complications, especially pneumonia, were shown in comparison to open procedure. However, whether total MIE has evident effects or not, as compared to hybrid MIEs, still remains unclear. Differences between RAMIE and MIE were reported to be marginal, though the advantage of lymphadenectomy, especially along recurrent laryngeal nerve, has been suggested. Centralization to high‐volume center evidently benefits esophageal cancer patients by improving short‐term outcomes. The definition of high‐volume center has not been established yet, though institutional structure and quality are thought to be important. Transmediastinal esophagectomy, currently developed, has a potential to be one radical option of MIE for esophageal cancer.

Published: February 2020

AbstractSevere gastrointestinal (GI) hemorrhage is a rare initial presentation in Crohn's disease (CD) and poses a therapeutic challenge for clinical care. Currently, there is no conclusive consensus or guideline on the treatment modalities for CD‐related GI bleeding. We present the case of a 21‐year‐old man with acute lower GI bleeding who accepted transcatheter arterial embolization to attain hemostasis. After 1 day of embolization, intractable abdominal pain happened and emergent laparoscopic exploration was arranged. Operation finding reported stenosis and chronic inflammation changes near ileal‐cecal valve. Besides, several bleeding sites and perforation are detected, which is different from splanchnic branch of embolization. Pathology of resected bowel reported transmural acute and chronic inflammation with fibrin and purulent exudates is shown on the serosa. CD is favored. In CD, the most common bleeding site in the literature is located at descending and sigmoid colon. To attain hemostasis, some literature studies raise concerns about embolic‐related complication of intestinal infarction. We would like to share a case of unusual bleeding site and provide consideration of embolization as an option for the treatment of CD.
