Objectives: To survey and analyze the distributive pattern of dentists working in private dental clinics in Al-Ahsa Governorate, Saudi Arabia. Methodology: This study used a unified questionnaire to survey private dental clinics in Al-Ahsa Governate from August to December 2019. Clinics were included if they had registered with the Ministry of Health and were operating in Al-Ahsa’s private sector. Clinics that were not available to visit during the survey period were excluded. During the study, participating clinics were visited and several data points were collected for each facility, including the total number of practicing dentists, year they joined the facility, and each clinician’s nationality, gender, and specialization. Results: The study showed 69 dental clinics registered with the Ministry of Health and serving the private sector in Al-Ahsa Governate. Sixty-six clinics (95.7%) agreed to participate. In the resulting survey of 301 practicing dentists, 73.8% were non-Saudi with Egyptians making up the largest national group at 27.2%. Among the Saudi dentists (n=79), 95% had joined their clinic in the last three years. For all participants the primary specialization was general dentistry (80.4%), the majority of whom were Saudi (31%) or Egyptian (27.7%). Among the dental specialists, 42.4% were orthodontists followed by maxillofacial surgeons at 27%. Conclusion: Private dental clinics in Al-Ahsa governorate are operated mainly by non-Saudi dentists. In the last three years, the number of Saudi general dentists joining private dental clinics has increased but there is still a need for dental specialists.

Marfan syndrome is an inherited autosomal dominant connective tissue disorder known for its multiple pathologies: musculoskeletal, pulmonary, ocular and cardiovascular. The criteria of Ghent facilitate its diagnosis. It requires a complete clinical examination as well as multiple imaging modalities. Early diagnosis and medical treatment with beta-blocker can delay the progression of aortic dilatation or possibly stop the pathological process of the aortic wall, as well as timely elective surgery are the key measures to improve the outcome of this disease. We report here the fortuitous discovery of a Marfan syndrome in a 19-year-old patient complicated with aortic dilatation.

The PISA report illustrates Indonesia's ranking in terms of critical thinking among students is still below the average of other countries from year to year. Critical thinking skills are very important skills that are trained in students to be able to compete in various fields.

In the Lubumbashi plain, the dominant soils are acidic Ferralsol that contain small amount of available phosphorus and nitrogen. The organic matter content is also limited. This study evaluated the effect of Arbuscular mycorrhizal fungi (AMF) on root colonization in Phaseolus beans growth performance and yield. Three soils with a pH 5.8; 6.2 and 6.5 respectively were included. We also studied the effect of increasing doses of P2O5 in beans by providing 25kg of P2O5/ha, 50kg P2O5 ha-1 in combination with AMF inoculation. The results show a high frequency of colonization at a pH of 5.8 (69%); a plant height of 56 to 58 cm with 10 leaves and 6 pods per plant for a yield of 2095kg ha-1. However, above pH 6.2, root colonization is low (31 to 61%) and plant height ranges from 27 to 39 cm with 4 to 6 pods for a yield between 631 and 1479 kg ha-1. The effect on plant response of 25kg P2O5 ha-1 in combination with AMF inoculation was statistically significant for all measured parameters. Finally, this study compared the efficacy of inoculum produced on three different way on colonisation efficiency of beans. Inoculum produced by using Plantago lanceolata as host species contained more spores and resulted in better-colonized roots compared to inoculum coming from Sorghum vulgare or clay inoculum.

L’observation de la pratique de classe et l’analyse didactique des programmes et des manuels de français d’avant l’introduction du curriculum basé sur les compétences au Rwanda, montre que la didactique de la grammaire de français suivait une démarche déductive qui met au centre de tout enseignement l’enseignant, le rôle de l’apprenant relégué au second plan. L’an 2008 fait que le français passe de la langue d’instruction à la langue objet d’enseignement, supplantée par l’anglais. L’intérêt d’apprendre et d’enseigner cette langue va sensiblement régresser. Aujourd’hui, pour relever l’enseignement efficace du français et de la grammaire en particulier, les efforts doivent converger vers l’intégration et la pratique des nouvelles démarches de la didactique de la grammaire. Leur coexistence n’y est pas pour rien car la résistance au changement persiste suite au degré de connaissance et d’utilisation de ces démarches et à l’attitude des enseignants et des apprenants face à la situation nouvelle. Notre recherche à la fois qualitative et quantitative, avait pour objectif de présenter la situation actuelle de la didactique de la grammaire du FLE dans les écoles secondaires au Rwanda, en vue de proposer une meilleure pratique de ses démarches. Elle a focalisé sur les élèves de la 2ème et de la5ème année, et leurs enseignants des six écoles sélectionnées du district de Kayonza au Rwanda. Leurs réponses au questionnaire et à l’entretien ont prouvé que l’enseignement de la grammaire du FLE dans ces écoles reste traditionnelle et déductive .Les démarches inductives et active de découverte sont quasiment inconnues et rarement utilisées, d’où la nécessité d’une formation et une pratique de ces nouvelles démarches pour une didactique efficace de la grammaire en particulier et du français en général.

Self-esteem is the basic human need or motivation. American psychologist Abraham Maslow for example included self-esteem in his hierarchy of needs for respect from others and inner self esteem. Respect from others entail recognition, acceptance, status and appreciation and was believed to be more fragile and easily lost than inner self esteem. According to Maslow, without the fulfillment of the self-esteem need, individuals will be driven to seek it and unable to grow and obtain self-esteem. The purpose of the study was to analyze the self-esteem between men and women physical education professionals. 17 women and 17 men undergoing Master of Physical Education students from Alagappa University College of Physical Education, Alagappa University, Karaikudi, Sivagangai district, Tamil Nadu were selected as subjects for the study at random. Self-esteem was measured by Self Esteem Inventory Scale by Dr. S. Karunanidhi (1996). The multidimensional questionnaire consists of 83 key items in the form of statements. It has both positive and negative items. The inventory measures six dimensions of self-esteem such as Competency, Global self-esteem, Moral and Self-control, Social esteem, Family self-esteem and Body and physical appearance. The data collected were statistically analyzed by using ‘t’ test to find out the significant difference between men and women physical education professionals on their self-esteem. The level of significance was fixed at 0.05. The result showed that men scored in global self-esteem and social self-esteem than women. No significant difference was found in Competency, Moral and Self-control Family self-esteem and Body and physical appearance between men and women physical education professionals.

Industrial actions are all forms of work dissatisfaction that can manifest in several ways like absenteeism, strike, high labour turnover among others. This has posed a lot of threats to all sectors of the economy and affected Nigeria society socially, economically and politically. Two theoretical postulations were used to investigate the perceived causes and effects of industrial actions in South West Nigeria. Survey research which involved 400 respondents from four randomly selected local governments was employed in the study. Data, which were sourced from both primary and secondary sources, were analysed using quantitative and qualitative methods. From the findings, the respondents revealed that hike petroleum price (85.3%), poor working conditions (66.3%), labour union interest (72.6%), members’ welfare (64.2%) and failure of management to keep to agreement (73.7%) were some of the factors responsible for industrial actions in Nigeria. Also, the respondents confirmed that undeveloped economy (70.6%), political stability (53.7%), development of entrepreneurial skills (66.3%), improved government administrative efficiency (70.5%), brain drain (80%), and increased poverty (60%) were the perceived outcomes of industrial actions on Nigeria political economy. On the efficacy of strike actions, respondents affirmed that labour union objectives are usually attained during strike (64.2%), and there were increases on wage labour (65.3%). Based on the findings, strike favours the workers, and negatively affects the nation and government in the long run. Thus, it was recommended that, there is need for stable labour-management relations between the government, industries and employees that will enhance a good bargaining environment. Also, there is need to improve on minimum wage policy of the government for the employees so as to improve the welfare of the employees and reduce the incidences of strike actions.

In view of the timeliness and accuracy of traditional state recognition algorithms, this paper proposes an improvement measure for foreground segmentation and target recognition. Foreground segmentation is to model the background information in the scene before recognizing the image, to separate the foreground target from the scene, at the same time to reduce the impact of noise, shadow and other environmental changes as much as possible, and then segment the target through a sliding window strategy. Target recognition is improved with reference to the PRN network and anchorboxes mechanism, and a more advanced clustering k-means++ algorithm is applied. The method has low error rate, high signal-to-noise ratio and fast processing speed. Finally, the proposed improved algorithm is applied to device status recognition, which shows the advanced nature of the algorithm.

Brief Background: Dentistry is facing its darkest hour yet, with the growth and spread of the Coronavirus pandemic. Dental surgeons are at the highest risk of contracting and transmitting the Coronavirus, alongside paramedics, nurses, and other healthcare workers. Dental clinics across the country were shut for over two months. With the pandemic still on the growth curve, there is no hope of revival anytime soon, compounded by zero earnings by dental practitioners and staff at clinics. To our knowledge, no study addresses the dentist’s perspective in such testing times, where they are entirely restricted to the confines of their homes. Aim: To assess the effects of COVID-19 and the lockdown on Indian Dentists and their practice. Materials and Methods: A self-designed online exploratory questionnaire of 18 questions was distributed to 400 potential responders. This cross-sectional study was conducted through an online survey questionnaire among dentists of Maharashtra in India. Dentists were enquired for demographics, experience, education and questions based on the current scenario and was used to give results among the study population. Results and Discussion: Out of the Four hundred dentists who were approached, a total of Two hundred and twenty subjects returned the questionnaire. 38.2% dentists' clinics were open but seeing lower patient volume than usual and 31.8% dentists were closed but seeing emergency patients. Also 28.2% dentists were closed and not seeing any patients. All the dentists replied in affirmative when asked if the virus and lockdown affected their practice. 69.1% dentists did attend to patients on emergency basis and the same percentage of dentists practiced teledentistry. 68.2% dentists were facing problems with their rents, wages and payments related to their practice. 80.9% of dentists were prepared to reopen their practice and 53.6% of dentists were planning to increase the treatment charges. 31.5% of dentists had a stock of PPE which would last those 1-6 days and 25% had a stock lasting them more than a month. 47.3% were highly concerned regarding the risk of transmission of Covid-19 to themselves, their team and the patients. Summary and Conclusion: With the recent claims the Covid-19 is here to stay for a while, it is essential that dentists must be fully prepared before providing services and must attain proper awareness to limit the disease spread.
