Published: September 2020

Objetivo: Discorrer a respeito da ponte miocárdica (PM), com destaque às descrições morfológicas, as implicações clínicas, o diagnóstico e o seu tratamento. Revisão bibliográfica: A PM acomete majoritariamente a artéria coronária descendente anterior esquerda. Na clínica, observa-se uma minoria sintomática, mas deve ser considerada em pacientes com baixo risco para doença coronariana aguda e com sintomas de angina instável ou estável. As principais implicações clínicas relacionadas à PM são aterosclerose e isquemia miocárdica. Para o diagnóstico, a tomografia computadorizada multislice das coronárias e a angiografia coronária convencional são os principais exames utilizados, em que avaliam a compressão da artéria coronária por PM durante a sístole. Há uma discrepância significativa entre a prevalência dos exames in vivo e na autópsia. Como tratamento, a intervenção medicamentosa, cirúrgica e/ou percutânea via stent podem ser realizadas, de acordo com o quadro clínico de cada paciente. Considerações finais: A PM permanece um tema controverso, visto sua elevada parcela assintomática, mas de suma importância para a cardiologia clínica e intervencionista nos casos sintomáticos.

Authors: Goncharov I. L. , Gorelova O. A.
Published: September 2020

The schemes of the decision-making process of an individual when consuming various goods and services using the components of economic psychology have been considered. Relevant from the point of view of economic psychology characteristics of buyer behavior that have a direct impact on his attitude to the price level of a product or service and on his reaction when the price changes for them have been presented and reviewed. The used “models” of consumer behavior of motivation, explaining not only the purchase by him of this product, but also his decision to have this product have been shown. Building models of purchase motivation allows manufacturers not only to explain consumer behavior, but also to influence it. Knowing all these nuances and skilful use of them, manufacturers have the opportunity significantly facilitate the pricing process for their goods and make a more accurate calculation of the “fair” price, which will not alienate the consumer. Two global approaches to segmentation of the consumer market have been considered, the use of which allows the manufacturer to assess the company’s competitiveness, assess the market size, and assess the customer’s commitment.

Published: September 2020

The reliability evaluation of the predicted binding constants in numerous models is also a challenge for supramolecular host-guest chemistry. Here, I briefly formulate binding isotherm with the derivation of the multivalent equilibrium model for the chemist who wants to determine the binding constants of their compounds. This article gives an in-depth understanding of the stoichiometry of binding equilibrium to take divalent binding equilibria bearing two structurally identical binding sites as an example. The stoichiometry of binding equilibrium is affected by (1) the cooperativity of complex, (2) the concentration of titration media, and (3) the equivalents of guests. The simulations were conducted with simple Python codes.

Condiciones y medio ambiente de trabajo en salud: modelo conceptual para áreas remotas y rurales
Authors: Antonietti Laura , Ortiz Zulma , Esandi María , Duré Isabel , Cho Malhi
Published: September 2020

Se propone un modelo conceptual sobre condiciones y medio ambiente de trabajo en salud que integra la evidencia disponible para facilitar el diseño y la evaluación de intervenciones orientadas a mejorar la atracción, captación y retención del personal de salud en el primer nivel de atención de áreas rurales y remotas.

Se consultó la evidencia teórica, empírica y testimonial para fundamentar la propuesta y se sintetizaron 15 modelos difundidos en los últimos 20 años. El artículo da cuenta de la diversidad de perspectivas y la complejidad que conlleva establecer las dimensiones que deben considerarse en una propuesta que sea útil para aplicar a las políticas de recursos humanos en salud.

El modelo propuesto incluye cuatro categorías de componentes: factores del contexto externo, factores organizacionales, condiciones del empleo y del trabajo, y factores individuales. Los límites entre los componentes –así como el peso y la influencia de cada uno– varían en función de la relación entre ellos y de la interacción con el medio, por lo que su interpretación debe adecuarse al ámbito en que se pretenda aplicar. A partir de este modelo conceptual, el diseño y la evaluación de las intervenciones dirigidas a incrementar la disponibilidad de personal de salud –en particular en el primer nivel de atención de áreas rurales y remotas de la Región de las Américas– deberían surgir de una interacción entre las políticas de salud y empleo, y las realidades y expectativas de los trabajadores y las comunidades.

Paradigma adalah cara berpikir, kerangka pikir atau cara pandang terhadap suatu obyek. Ada tiga paradigm yang penting yang mempengaruhi teori hukum. Paradigma Aristotelian adalah kerangka berpikir bahwa alam semesta ini adalah sebagai keteraturan atau suatu tertib (order) yang sudah pre-established, bahwa sudah tercipta dan terjadi sejak awal, yang bersifat mutlak. Kaitannya dengan hukum bahwa hukum adalah aturan yang terdapat dalam undang-undang yang bersifat mutlak sebagai norma. Paradigm Cartesian (Rasional) yang mengagungkan rasio-logika yang memandang bahwa alam gagasan dan kemampuan manusia sebagai sumber pengetahuan manusia tentang dunia berikut isinya. Paradigma Gallilean disebut Saintisme yaitu paham bahwa seluruh pengetahuan manusia harus diperoleh berdasarkan rasionya sebagaimana yang telah teruji berdasarkan fakta empirik. Kaitannya dengan hukum bahwa sebuah keniscayaan yang dapat diterima rasio. Ketiga paradigma tersebut mempengaruhi teori hukum, seperti teori hukum positif-rule of law. Paradigma Aristotelian lahir teori hukum positivis-post positivis, paradigm Cartesian lahir teori hukum kritis dan paradigm Gallilean lahir teori hukum konstruktivis.

Published: September 2020

This study was designed to investigate the relative effects of observing video, point-light, and stick-figure model demonstrations on the development of internal motor representation of a highly complex sport skill. Forty one novice female and male students were randomly assigned to video, point-light, stick-figure and no-demonstration control groups. Internal motor representation was evaluated by a computer - based test using the error detection paradigm. Participants had to view ten digital photos representing different phases of a Baseball pitching and were instructed to identify by mouse-clicking various movement errors. The test was respectively performed after 5 familiarization trials (pre-test), 3 acquisition blocks of 10 trials (post-test) and one week without practice (retention test). Participants observed related model demonstrations prior to each acquisition block. Results showed that demonstration groups improved their scores in either post-test or retention test; however these improvements were not statistically significant. Moreover, there was no significant difference between groups either in post-test or retention test. The findings are discussed in terms of difficulty of errors, insufficient amount of physical or observational practice, and small sample size.

Authors: Savu Vasile-Cătălin
Published: September 2020

The increase in players' performance due to the development of effort capacity has become more and more dominant in recent years, because of the ever-increasing contribution of science. The maximization of the connection between the physical, technical and tactical aspects of the soccer game focuses on designing the training session and on the clear justifications of the specific methods used in the modern game. To comply with a particular technical or tactical game system or plan, players must be able to physically carry out the requirements of this approach. If traditional football training used to focus primarily on player's technical and tactical development, to the detriment of physical training, the people involved in the educational processes have changed this with the intention of giving physical training a greater time span.

The study was conducted at the „Stefan cel Mare” Gymnasium School in Putna, on five children aged between 7 and 10 years old. This experiment took place during a school year. The research is based on the premise that play (playful activities) conceived as therapy is part of the new trend of teaching-learning methods, which aim to transform the role of the teacher and to give new possibilities to the child with certain psychomotor disorders. The results have highlighted that the application of different ludo-therapy activities in physical education and sport lessons to children without mental deficiencies, but which have different psychomotor disorders, has led to the improvement of some components of psychomotor, namely static and dinamic balance, general coordination, segmental coordination, ocular - motor coordination and spatial orientation.

Reaching certain goals that are specific to a field presupposes the creation of a plan through which the goals will be reached. Once created, the plan, the strategy aims to select and perform the methods so that the goals will be reached. This paper aims to emphasize the teaching strategies for reaching the goals of physical education that are specific to the schools of Romania and the United Arab Emirates. This research was based on the hypothesis stating that a comparative study regarding the teaching strategies in the "Al Nahda" National School and the ones in the "Dr. Alexandru Șafran" School could emphasize the cultural differences between the two schools and the elements that cold lead to common strategies in teaching physical education to 11-12 year old pupils, no matter where they are. The research methods that facilitated the study were: the documentation method, the inquiry method, the statistical-mathematical method for data interpretation.

Published: September 2020

School success is the mark of school performance and shows the level of adaptation of pupils to school tasks. School success implies the development of aptitudes, intelligence, practical spirit, applicative spirit and experimental spirit. An important role in remarking school success is played by teachers who need to know the potential of each pupil, to force it if necessary to be highlighted as functional and to engage in learning. Developing the student's self-esteem for the success of the school is a long-lasting process with many objective and subjective determinations. The degree of adaptation to school activity shows the student's ability to know, to assimilate, to accommodate the external requirements, the planned educational and educational influences along with his desire and ability to mold himself, to accommodate himself, sense. One of the basic factors of school success is school intelligence.

Authors: Leuciuc Florin Valentin
Published: September 2020

Sport performance in handball requires a cumulative amount of individual and collective factors that contribute to achieve the goals. The aim of this study is to contribute to the theory of the somatic model of top team handball players. The basic working method is a retrospective and descriptive analysis of the anthropometric indices of the players that participated in handball top competitions (European Championship, World Championship, Olympic Games). The data were collected and processed on the playing posts but also on the total of the top 4 teams. The monitored and analysed indicators are: height, weight, body mass index and height -100 / weight ratio. These data are a benchmark for updating the somatic model in the top female handball players, with implications up to the level of primary selection to ensure the base of handball from which top players will be raised.

Published: September 2020

This research study aim was to assess muscle fatigue of the dominant and non-dominant lower limb (knee flexion/extension, hip abduction/adduction and ankle plantar/dorsoflexion), using Biodex System 4 ProTM. This investigation tested the lower limb muscles during isokinetic concentric/concentric mode at 60o /sec,120o /sec, 300o /sec,450o /sec. Hip abduction/adduction of the right and left side values range for total work from 101.6 J to 528.1 J ; work first third from 32.7 J to 164.7 J; work last third from 25.2 J to 183.7 J. Knee flexion/extension of the right and left side values range for total work from 443.2 J to 792.2 J; work first third from 135.7 J to 258.7 J; work last third from 124.1 J to 249.2 J. The present study suggests that as we change the velocity, muscle fatigue can affect the kinetic lower limb chain.

Authors: Popescu Ofelia , Leonte Nicoleta
Published: September 2020

Intellectual disability is one of the most complex phenomena, involving interventions from the medical, psychological, pedagogical and sociological spheres, interventions that must be carried out as early as possible and that lead to the shaping of the child's personality. Despite the large number of problems and limitations, children with intellectual disabilities can acquire motor skills, but, for this, they need special conditions adapted to their own abilities, coupled with permanent supervision. This paper aims to analyze the level of handling skills training in children who suffer from the Down syndrome, following the implementation of a kinetic stimulation program that uses applicative paths. The research brought together a sample of 19 children suffering from the Down syndrome aged 3 to 8. The results obtained showed an improvement in the level of the fundamental motor skills training (objects handling) of the research subjects.
Vestibular Reeducation and Its Effectiveness in Reducing the Vertigo Symptoms
Authors: Șlicaru Adina-Camelia , Nemțanu Andra-Mihaela
Published: September 2020

Vertigo is a symptom that is common to multiple disorders, from orthopedic and cardiovascular to neurological, affecting in many cases the patient's daily life activities. That is why, to help fight this symptom, this paper aims to prove the effectiveness of vestibular reeducation therapy. French Alain Semont introduced and developed the vestibular reeducation in 1968, his work being continued by Michel Toupet. Vestibular physical therapy took off around 49 years ago, while in Romania it is still quite a new method, much less explored by the Romanian experts. Currently there are few studies in this field, being a specialization that is almost non-existent among the Romanian therapists.

Socializing in tourist march also targets the adolescent and the group. Skills and habits, as well as rules assimilated by adolescents in tourist march, will be effective in any other social sphere. Tourist activities including tourism marches are very attractive, and those who practice them are convinced of their benefits, including socializing. The social, economic and environmental aspects of the young people of the last years impose the necessity to use the pedagogical potential of the tourism marches, for the formation of the collectivism, the mutual assistance and the activity in the group and other social skills necessary for the adolescents. Thus, these aspects give us the possibility to mention that, the tourism marches have an enormous psychological and pedagogical potential for the socialization of adolescents. The analysis of scientific literature allowed us to determine basic and theoretical approaches that are based on ideas about various aspects of socialization.

Published: September 2020

The research was conducted at - Sulaimani Polytechnic Universit (SPU), Bakrajo Technical Institute in Sulaymaniyah city, Iraq in begging of 2018. Three different sizes and varieties Ecuadelje of bean seeds were used and treated. Water-soaking, dilute acid soaking, and dilute base with scarification soaking. They were distributed in 36 pots by using CRBD with three replicates. The results showed the significant differences only with the effect of seeds size from the period of sowing seeds to the end of germination. The small size seeds had significant differences compare to the others. But the effect of removal test was high significant in all studied characteristics. Seeds which socked with diluted base and diluted acid had significant differences compare to the other treatments form the initial to the final stage of seeds germination. The interaction between seeds sizes and removable testa treatment showed significant differences among small size seeds which treated with diluted HCl during the initial and final stage, and the large size seeds treated with diluted NaOH. Seeds scarification treatment did not show any positive effects in both of germination periods, but showed significant differences in the percentage of initial and final germination. We suggested to sock the broad bean seeds in one of diluted bases or diluted acids and scarification of seed treatment in order to stimulate germination percentage reduce of the germination period and develop broad beans stored seeds germination.
COST – BENEFIT ANALYSIS FOR NIGERIAN NATURAL GAS PIPELINE INVESTMENT
Authors: Nwabueze Gift , Ogbonna Joel , Nwaozuzu Chijioke
Published: September 2020

This paper performs cost-benefit analysis of a pipeline infrastructure project based on a given natural gas demand in order to estimate the net present value and payback time for natural gas pipeline investment in Nigeria. The result of the cost-benefit analysis indicates a positive net revenue and net present value (NPV) at the current regulated transport cost and availability factor for gas pipelines in Nigeria. However, with a payback period of 14 years, a natural gas pipeline project in Nigeria is likely to lose-out investment capital to other competing investments within the oil and gas sector. Scenario analysis indicates that by doubling the regulated transport cost with a 50% tax reduction, the pipeline investment results in a much higher NPV and a payback of 4 years, which is more acceptable to investors.
Investigating Science Researchers’ Presence on Academic Profile Websites: A Case Study of a Canadian Research University
Authors: Zhang Li , Li Chen
Published: September 2020

Researchers are increasingly using academic profile websites to organize and showcase their research outputs. Using the faculty at the science departments of the University of Saskatchewan, Canada as the study object, this research explores how science researchers used four academic profile websites: ResearchGate, Google Scholar Citations, Academia.edu, and ORCID. It was found that 78% of the researchers had established at least one academic profile, with ResearchGate being the most popular platform, Google Scholar Citations the second, followed at some distance by ORCID and Academia.edu. A high percentage of ORCID users did not list any of their publications, meaning their presence on ORCID was merely symbolic. We also found that the social interaction functions provided by ResearchGate were not well adopted. Findings from this study call for the improvement of the workflow of adding publications to ORCID profile.
