Les effacements de consommation électrique et le surplus des acteurs énergétiques
Authors: Clastres Cédric , Geoffron Patrice 
Published: January 2021

L’introduction et la valorisation des effacements de consommation dans le marché électrique suscitent un intérêt croissant, à mesure de la montée de besoin de flexibilité. À partir de la structure industrielle développée par Chao (2011) et des données du marché spot « day- ahead » fournies par la Bourse européenne de l’électricité (Epex), nous développons un modèle simulant l’introduction des effacements dans le marché électrique français avec fonctions d’offre et de demande estimées. Nous montrons que, pour que l’effacement améliore le bien-être collectif et soit créateur de valeur pour les différentes catégories d’acteurs impliqués, différentes conditions s’imposent, notamment des coûts de mise en place limités et des transferts entre agents dépendant du risque encouru ou de la désutilité subie.Classification JEL : D61, L11, L52, L94, Q41.

Authors: Nurunnabi Mohammad , Almusharraf Norah 
Published: January 2021

Background The coronavirus disease (COVID-19) has affected the entire globe, and various mythologies argue about its diagnosis, cure, and prevention. Globally, as of September 18th, 2020, there have been 30.055 million confirmed cases, including 0.943 million deaths. The nationwide closures are impacting over 60% of the world's student population. This study aimed to explore the social distancing policies and universities’ reopening after COVID-19 in G20 countries (19 member countries and the European Union). Design and Methods The study is based on documentary analysis. G20 members represent around 80% of the world's economic output, two-thirds of the global population (including more than half of the world's poor), and 75% of international trade. Based on documentary analysis, the study revealed that there is a policy dilemma among G20 countries regarding school reopening and a variety of conflicting policies within each country. Results Based on a sample of 838 universities in the USA, 66% of universities (552 of 838) plan for in-person instruction, while only 7% are planning for a completely online teaching mode in the fall 2020 semester. Conclusions Interestingly, none of the private universities in this study are planning to implement an online teaching mode. Policymakers need an integrated set of policy guidelines for school reopening, considering the evaluation of current COVID- 19 pandemic circumstances and social distancing capacity.

Published: January 2021

Background The spread of coronavirus (COVID-19) has resulted in a drastic alteration to billions of individuals’ emotional, physical, mental, social, and financial status. As of July 21st, 2020, there had been 14.35 million confirmed cases of COVID-19, including 0.60 million deaths in 216 countries. Design and Methods The study explores health and wellbeing in universities within the G20 countries (19 member countries and the European Union) during the COVID-19 pandemic. The sample selection of these countries was considered since it serves around 80% of the world's economic output, two-thirds of the global population (including more than half of the world's poor), and 75% of international trade. Specifically, due to this public health concern, schools’ nationwide closures are impacting over 60% of the world's student population to promote their quality of life and well-being. Results This study investigates the G20 policies and procedures within higher education regarding health and well-being measures during the COVID-19 epidemic. The findings reveal that the lockdown, social distancing, and self-isolation requirements are stressful and detrimental for many individuals and have caused students’ health and well-being concerns. Conclusions Several countries within the G20 have taken significant steps to support health and well-being issues for university students; however, numerous countries are far behind in addressing this issue. Hence, government leaders of G20 countries, policymakers, and health providers should promptly take the necessary measures to regulate the outbreak, improve safety measures to decrease disease transmission, and administer those who demand medical attention.

Authors: Chutia Happy , Srivastava Tripti , Bhattacharyya Himashree 
Published: January 2021

AIM:
The aim of this interventional study was to introduce classroom quality circles (QCs) among first-year MBBS students, to assess the effectiveness of QCs on learning experience of the students, and to evaluate the students' satisfaction level during the process of learning.

MATERIALS And METHODS:
A problem pool was created through a questionnaire. The study was carried out in the department of biochemistry, for a period of 6 months. Student's quality circle (SQC) group of five students was created. Then, feedbacks were collected from students by SQC after every class/topic delivered, and fortnightly meeting was held between the SQC group and faculty members of the department, and issues were brought to focus depending on these feedbacks collected by them. Possible initiatives and improvements were done on teaching–learning strategies depending on the outcome of these discussions.

RESULTS:
The effectiveness of SQC group was assessed by a pre-post questionnaire (Questionnaire-3) feedback from the students and scoring was done based on 5-point Likert scale. There was a statistically significant difference (P = 0.009) between the mean of pre-post questionnaire. To analyze the students' satisfaction level, a set of questionnaires were given to them and scoring was done. Thirty-four students agreed, 11 students were neutral, and 6 students were disagreed, that introduction of SQC was effective in solving their problems related to teaching and learning of biochemistry.

CONCLUSION:
SQC creates an environment of student centric, fairness, student empowerment, improving solving skills. Implementation of student-generated feedback through introduction of SQC has improved the quality of the course as well as its delivery. It complements and supplements in achieving students intended learning outcome and hence may contribute to overall learning quality in the long run.

Authors: Jothula Kishore Yadav , Sreeharshika D. 
Published: January 2021

BACKGROUND:
Road traffic continues to be a major developmental issue and a public health concern. Road accidents in India kill almost 1.5 lakh people annually, and India accounts for almost 11% of the accident-related deaths in the world. Prevention of road traffic accidents is very crucial by creating awareness and taking proper measures toward road safety.

AIMS:
The aims of this study were to assess the knowledge about road safety regulations and to assess the attitude and practices regarding road safety regulations.

SETTINGS AND DESIGN:
This cross-sectional study was conducted in a pharmacy college.

SUBJECTS AND METHODS:
Study participants were all 4 academic years' pharmacy students who know driving two- or four-wheeler motor vehicle. Data were collected from a sample of 132 by predesigned pretested semi-structured questionnaire.

STATISTICAL ANALYSIS USED:
Data were presented in proportions with confidence interval using SPSS ver. 22.

RESULTS:
81.1% of the participants knew the minimum age to obtain driving license. Only 16% follow the road signs strictly and 76% wear helmet for long-distance ride. Poor attitude was observed for wearing helmet for short-distance ride, pillion rider wearing helmet, and drink and drive.

CONCLUSIONS:
Majority of the participants were aware of road safety regulations. In spite of having positive attitude toward road safety measures by participants, they could not translate attitude into practice.

OBJECTIVE:
According to the World Health Organization, estimates about 1,800,000 people lived with disability in Tehran. Against there is little evidence of physical access to rehabilitation facilities in Tehran. This study is aimed to assess the physical access to physical rehabilitation facilities in Tehran and compare it with the country.

METHODS:
This is a cross-sectional study conducted since January to April 2017. We used a master facilities list of rehabilitation facility that developed in Iran to collect the information. The samples of this study included all existing physical rehabilitation centers in Tehran province. Data analysis was done using the SPSSr version 21.0 (SPSS Inc., Chicago, IL).

RESULTS:
The results showed that rehabilitation facilities existed at different levels, including inpatient (10.51), outpatient (224.28), community based (36.72), and long-term care (4.96)/1,000,000 populations. Rehabilitation services are provided by rehabilitation professional including: Physical medicine and rehabilitation specialists (8.7), physiotherapists (132.89), occupational therapists (57.4), speech therapists (42.11), and audiologists (48.84) (in 1,000,000 populations).

CONCLUSION:
Tehran needs to increase the physical access to rehabilitation facilities and compared with country was disproportionate physical access to facilities in most cases. It is necessary to establish an interdisciplinary referral system between different rehabilitation providers.

Published: January 2021

INTRODUCTION:
Childbearing is an important event in a couple's life. The parents might have children with disability that affected on their well-being after the children's birth. Well-being considered as an important aspect of a couple's quality of life which may alter the future of their fertility. The present study was conducted to the association of psychological well-being and fertility intention in parents with educable intellectually disabled children.

METHODS:
The study was a cross-sectional descriptive research conducted on parents of children with intellectual disability (n = 386). Parents were selected randomly of schools of exceptional education and welfare. The data were collected using Ryff's scale of psychological well-being, demographic information, and fertility intention questionnaire. Data were analyzed using descriptive and analytical tests including independent t-test, Chi-square test, Mann–Whitney U-test, and Logistic regression.

RESULTS:
The majority of parents (83.9%) reported the negative infertility intention. Despite the mean score of well-being in parents without fertility intention (75.71 ± 11.67) was lower than parents with fertility intention (76.90 ± 11.27), the difference was not statistically significant (P > 0.05). The logistic regression analysis indicated that the parents' age and number of children with intellectual disability were predictors of fertility intention (P < 0.05), and their increase decreased the fertility intention.

CONCLUSION:
It seems that the lack of difference in psychological well-being scores between the two groups of parents might be due to the equal severity of disability in children. The results also indicated parents' age and the number of children correlated with fertility intention. The findings can be used to advance counseling programs in the field of healthy reproduction for this group of parents.

Authors: Hafizi Leili , Razmjoo Nastaran , Yousefi Fatemeh , Azizi Hoda 
Published: January 2021

BACKGROUND:
During the immediate post delivery period, women are particularly susceptible to distension of the bladder. Complementary and alternative medicine is becoming an established intervention modality within the contemporary health care system. However, very little is known about the impact of foot reflexology on the urinary system. The aim of this study was to evaluate the effect of the most popular type of complementary therapy (the foot reflexology) on first voiding time following elective cesarean section without urinary catheter.

METHODS:
This experimental study was performed on 61 pregnant women in Pastor Hospital, Mashhad, Iran, who met the inclusion criteria. Accordingly, participants were randomly allotted to either treatment or control groups. The intervention group received a single 20-min foot re?exology session at 2–3 h after the surgery. The time taken for first void was recorded by research assistant that blinded to the allocation of groups. The findings were recorded and analyzed with the SPSS software by using of Chi-square, independent t-test, Mann–Whitney, and Fisher exact methods P < 0.05 was considered as statistically significant.

RESULTS:
Using General Linear Model (GLM) for controlling of confounding variables, the results of t-test showed significant differences between two groups in terms of first voiding time (P = 0.001) following surgery.

CONCLUSION:
It seems that the use of foot reflexology as a nursing care plan to prevent urinary retention after cesarean section without urinary catheter does shorten first voiding time and increase maternal satisfaction.

Published: January 2021

Background:
We investigated the effects of spirulina under high-intensity interval training (HIIT) on levels of nesfatin-1, omentin-1, and lipid profiles in overweight and obese females.

Materials and Methods:
This is a randomized, quasi-experimental controlled, single-blind with a pre- and post-test design, in which twenty overweight and obese women (body mass index = 29.32 ± 3.01 kg/m2, age = 21.55 ± 1.76 years), were randomly divided into the following groups: HIIT + spirulina (n = 10) and HIIT + placebo (n = 10). Running anaerobic sprint test was used for HIIT protocol consisting of six intervals at 35 m maximal speed runs, with a rest of 10 s in each trial (3 times/week, 4 weeks). HIIT + spirulina group received 500 mg of the spirulina pills twice daily for 4 weeks and the second group took placebo.

Results:
There was a significant increase in serum levels of nesfatin-1 in HIIT + spirulina (P < 0.0001) but not in HIIT + placebo (P = 0.61) group. Furthermore, results indicated a significant difference between two groups with respect to serum levels of nesfatin-1 (P = 0.04). Serum levels of omentin-1 significantly increased in both groups (P < 0.05). However, there was no significant difference between two groups (P = 0.49). In addition, results showed no significant inter- and intra-group differences in total cholesterol levels, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol between groups (P > 0.05).

Conclusion:
The spirulina under HIIT increased levels of nesfatin-1 and omentin-1 with no effects on the levels of lipid profiles in overweight and obese females.

Authors: Shekarriz Ramin , Alikhani Reza , Ghasemi Mohaddeseh , Navaei Reza Alizadeh , Hashemi-Soteh Mohammad Bagher 
Published: January 2021

Background:
E-cadherin (CDH1 gene) is a protein involved in cell-cell adhesion. There are reports on the association of –160C > A (rs16260) and –347GA > G (rs5030625) polymorphisms in the 5′-promoter region of the CDH1 gene with tumor development and progression of gastric cancer. This study aimed to examine the potential relationship between these two polymorphisms and gastric cancer in patients from Mazandaran province, Northern Iran.

Materials and Methods:
A case–control study was conducted to test 97 patients and 95 healthy controls. Genomic DNA was extracted from peripheral blood followed by polymerase chain reaction amplification. Genotyping analysis was carried out using restriction fragment length polymorphism analysis for two potentially functional polymorphisms.

Results:
Heterozygous genotype GA/G versus GA/GA of rs5030625 (–347 GA > G) was found to be associated with increased risk of gastric cancer in the people studied (odds ratio = 5.73, 95% confidence interval = 2.11–15.56, P = 0.001). Furthermore, AA or CA genotype in –160C > A polymorphism did not show any increased risk of gastric cancer (P = 0.559).

Conclusion:
The present study revealed that GA/G genotype of rs5030625 (–347 GA > G) polymorphism is associated with gastric cancer in Northern Iran.

Authors: Keya Tahmina Afrose , Fernandez Kevin , Kharkwal Kailash C. , Habib Nasrin 
Published: January 2021

Background:
Malaysia has a high standard of health-care system, including antenatal care (ANC) services.

Objective:
This cross-sectional study was carried out to assess the impact of regular ANC visits on outcome in a rural community in Malaysia from September to November, 2019, in village Kampung Merbok in Kedah, Malaysia.

Method and Materials:
A pretested semi-structured questionnaire was used as a tool for data collection among the women who gave birth in public or private health-care centers. Association between the various components of ANC and pregnancy outcome was examined using multivariate logistic regression analysis, and Chi-square test/Fisher's exact test was used to interpret the association between the ANC visits and the outcome variables.

Result:
Among the respondents, 39 (78%) had more than four ANC visits. Fourteen (28%) respondents had adverse pregnancy outcome. All nonattendees had adverse outcome. Only 6 (12%) women (95% confidence interval: 3.22, 20.78) had a history of cesarean section. This study found statistically significant association between maternal ANC visits and maternal and neonatal outcome variables (P < 0.05). Pearson's correlation test also revealed the strong relationship between ANC and the outcome variables (P < 0.0001).

Conclusion:
In this study, mothers having regular ANC visits experienced better pregnancy outcome compared to those nonattendees. Nevertheless, it is necessary to adhere to a minimum level of four ANC visits for all pregnant women. More health promotion programs are required focusing on improving women's awareness of the necessity of ANC throughout their pregnancy.

Published: January 2021

AbstractThe Parisi formula is a self-contained description of the infinite-volume limit of the free energy of mean-field spin glass models. We showthat this quantity can be recast as the solution of a Hamilton–Jacobi equation in the Wasserstein space of probability measures on the positive half-line.

Published: January 2021

Objectives: This study aims to evaluate nailfold capillaroscopic pattern in patents with fibromyalgia and to assess the relation of capillaroscopic parameters with clinical variables and disease-related measures.
Patients and methods: This cross-sectional, case-control study included 60 participants (4 males, 56 females; mean age: 44.0±8.2 years; range, 26 to 64 years) between August 2019 and November 2019. All participants were divided into two groups as the primary fibromyalgia group (n=30) who met the 2016 modified American College of Rheumatology Diagnostic Criteria for Fibromyalgia and the control group (n=30) consisting of age- and sex-matched healthy individuals. Nailfold capillaroscopy was performed by a digital microscope under a magnification of 200X. Capillary density, capillary loop diameter, number of dilated, giant and neoangiogenic capillaries, capillary shape, number of avascular areas, micro-aneurysms and micro-hemorrhages were evaluated by an assessor who was blind to the group allocation. In the fibromyalgia group, Widespread Pain Index, Symptom Severity Scale scores, and Fibromyalgia Severity scores were calculated. Health status and presence of benign joint hypermobility syndrome (BJHS) were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) and revised Brighton criteria, respectively.
Results: Of the capillaroscopic parameters, the mean capillary loop diameter, number of micro-aneurysms, avascular areas, and neoangiogenic capillaries were significantly higher in the patient group compared to the controls (p<0.001, p=0.016, p=0.038, and p=0.04, respectively). Nailfold capillaroscopic findings did not significantly differ between the patients with (n=16) and without concomitant BJHS (n=14). Of the disease-related measures, only FIQ score showed a weak correlation with the number of dilated capillaries (p=0.324).
Conclusion: Patients with fibromyalgia have distinct capillaroscopic patterns than healthy population. Capillaroscopic features, in general, are not related to clinical variables and disease-related measures.
