Published: November 2019

La política fiscal es una herramienta fundamental en la gestión pública y la ciencia económica del Ecuador, la estabilidad económica del país depende en gran medida de esta política, razón importante por la cual es necesario realizar análisis que permitan contextualizar su planificación, ejecución y resultados.

En el presente trabajo queremos analizar la relación que se presenta entre la inflación y el empleo, según Phillips la relación es inversamente proporcional, según The global economy la relación no se evidencia que cumpla con aquella característica, al contrario, gráficamente se observa una relación con tendencia directa.

Así mismo la relación entre el gasto público y la presión fiscal, también es necesario su análisis, del cual se desprende principalmente que a partir de 1993 hasta 1999, el gasto público es mayor y a partir del 2000, es la presión fiscal la mayor.

Balance state development and correction methods in preschool children
Authors: Bochkov Pavel
Published: November 2019

In the article the methods of balance function formation in preschool children with musculoskeletal system disorders are systematized and analyzed. In the basis of dynamic stability correction in this children contingent were laid phylogenetically predisposed mechanisms of the postural aplomb system, reflected in periods of early
child ontogeny: vestibular - visual - proprioceptive - gift - oculomotor. To improve each of these input channels of the aplomb postural system, a specific technique algorithm for the development and correction of the balance function in preschool children with motor disorders was developed. For the vestibular channel it is suggested to
use methods of hydraulic inverted (mirroring), "weightlessness", smoothness (metered angular accelerations). For the visual channel you can use the methods of "dark room", "tuning fork", "dawn". Proprioceptive channel improvement of the postural aplomb system involves the use of gradually reducing methods of bearing surface area,
strengthening proprioceptive sensations (the method of "two fans"). The given canal of the child vestibular system can be developed using such methods as "topographic", "two-axis – one-axis", sensory stimulation, contrast method, and also the method of "stilts". The oculomotor system of child with balance state disturbances can be
improved by the method of expanding oculomotor space-time eyes possibilities, the method of the ball, as well as the method of visual selective object capture, separating it from a variety of objects or from fleeting environment. This classification of methods are given with their conditional division into natural, phylogenetic and ontogenetic predetermined, and artificial, based on the use of the subject-spatial component (equipment, simulators and inventory), as well as the use of the possibilities of information and computer technologies with reverse biological bonds.
The prospects of studying the development methods and correction of balance function in preschool children with motor disorders is the development of specific exercise complexes for each of the developed methods, followed by their practical testing in this children contingent.

Authors: Varvaruk Mariana
Published: November 2019

The article presents the conceptual foundations of dialogical competence formation in the context of Ukrainian language education of elementary school students. The author emphasizes that the ability to formulate and express their thoughts correctly is the key to success in life. It is proved that broadcasting is the main means of communication, meeting the various personal needs of people in communication. The author argues that in linguistics, language is defined as a kind of sign system that provides human thinking, communication with other people, that is, serves as a means of forming thoughts, perception of the surrounding reality, the exchange of information. Attention is drawn to the fact that since language and speech accompany a person in all activities
throughout life, it is appropriate to talk about the interconnection of all activities in speech communication, that is, speech competence, which is a component of communicative. The author notes that the competence approach in education is understood as the orientation of the educational process to the formation and development of basic competencies of the individual. It is specified that competence should be understood as a real requirement for students to acquire a set of knowledge, methods of activity, experience, attitudes in a certain field of knowledge,
qualities of the personality acting in society, and competence - as really formed personal qualities of the student and experience. The author emphasizes that the communicative-activity approach is one of the basic principles in the teaching of the mother tongue, under which the process of mastering the mother tongue should be carried out in the course of solving the students' oral tasks, arranged in order of increasing their complexity. It is emphasized that the principles of experimental study construction were: communicative orientation of dialogue teaching; the principle of situationalism in the teaching of first-graders in dialog speech; language training as an activity; the principle of speech and mental activity of students; the principle of individualization; gradual and systematic approach to learning dialogue. The author emphasizes the importance of the principle of communicative orientation, which involves the construction of a language learning process as a process of real communication. The prospects for further research in this area are identified.

Risks from Breathing Elevated Oxygen
Authors: Shykoff Barbara E. , Lee Rees L.
Published: November 2019

INTRODUCTION: Effects of breathing gas with elevated oxygen partial pressure (Po2) and/or elevated inspired oxygen fraction (FIo2) at sea level or higher is discussed. High FIo2 is associated with absorption problems in the
lungs, middle ear, and paranasal sinuses, particularly if FIo2 > 80% and small airways, Eustachian tubes, or sinus passages are blocked. Absorption becomes faster as cabin altitude increases. Pulmonary oxygen toxicity and direct oxidative injuries, related to elevated
Po2, are improbable in flight; no pulmonary oxygen toxicity has been found when Po2 < 55 kPa [418 Torr; 100% O2 higher than 15,000 ft (4570 m)]. Symptoms with Po2 of 75 kPa [520 Torr; 100% O2 at 10,000 ft (3050 m)] were reported after
24 h and the earliest signs at Po2 of 100 kPa (760 Torr, 100% O2 at sea level) occurred after 6 h. However, treatment for decompression sickness entails a risk of pulmonary oxygen toxicity. Elevated Po2 also constricts blood vessels, changes blood pressure
control, and reduces the response to low blood sugar. With healthy lungs, gas transport and oxygen delivery are not improved by increasing Po2. Near zero humidity of the breathing gas in which oxygen is delivered may predispose susceptible individuals to bronchoconstriction.Shykoff

Third-Culture Kid Pilots and Multi-Cultural Identity Effects on Pilots’ Attitudes
Authors: Tsz-Kin Chan Wesley , Harris Don
Published: November 2019

BACKGROUND: Current attempts to culturally tailor human factors training in aviation segregates cultural identities based on geopolitical, passport nationality, and is therefore poorly suited for (adult) ‘Third Culture Kids’ (TCKs) whose cross-cultural upbringing
has led to the development of multicultural individual identities that do not reflect their passport nationalities. In this study, respondents’ self-categorization of personal cultural identity, as opposed to passport nationality, was used to determine whether there were cultural differences
in airline pilots’ behaviors.METHOD: A survey with items imported from established scales was distributed to pilots of an international airline to measure pilots’ work values, flight management attitudes, and cultural dimensions, with respondents segregated into Western,
TCK, or Asian cultural groups.RESULTS: TCKs shared similar work values with Westerners, were similarly individualistic, had comparable preference for shallow command gradients, were similarly pragmatic in self-evaluation of performance under stress, and both had lower dependency
and preference for rules and procedures. TCKs scored in the middle between Westerners and Asians in automation preference attitudes, and on the cultural dimensions of power distance and uncertainty avoidance. TCKs did not share any similarities with Asians at all.DISCUSSION: The
results show that TCKs were neither assimilated into a mainstream culture, nor culturally “middle of the pack” as may be expected from their “East meets West” backgrounds. Having identified TCK pilots’ unique values, attitudes, and dimensions, practical implications
include changing training design to better suit TCKs’ cultural characteristics and the adaptation of airline management to cater for TCKs’ work values.Chan WT-K, Harris D. Third-culture kid pilots and multi-cultural identity effects on pilots’ attitudes. Aerosp

U.S. Statement of Demonstrated Ability Aeromedical Waivers
Authors: Mills William D. , Davis Joshua T.
Published: November 2019

INTRODUCTION: The Statement of Demonstrated Ability (SODA) is a type of U.S. aeromedical waiver used for disqualifying conditions that are not expected to change. About 21,000 (2%) U.S. pilots possess a SODA waiver.METHODS: We matched all pilot medical exams from the
FAA’s medical certification database from 2002 through 2011 to their respective accidents in the National Transportation Safety Board accident database. The association of SODA waivers and SODA conditions with the odds of an accident were explored using logistic regression techniques.RESULTS:
For 3rd class flight exams, the presence of a SODA waiver was not associated with the odds of an accident. For the 1st and 2nd class exams, the accident odds ratio (OR = 1.45) was statistically significant. Crop dusting operations accounted for 17 of the 40
accidents where SODAs were present and returned a significant accident OR = 1.68. SODAs were not associated with the odds of accidents during other commercial operations. Six SODA conditions (amputation, internal eye, external eye, visual fields, bone and joint, and miscellaneous) were also
found to have elevated ORs but were based on very small accident counts. NTSB investigators and the authors reviewed all accidents and none thought the SODA condition to be contributory.DISCUSSION: SODA waivers were not associated with increased accident odds except for crop dusting
operations. Six specific SODA conditions also had elevated odds of an accident, but there was no evidence they contributed to the accidents. Overall, U.S. pilots with SODA waivers appear to have a satisfactory safety record.Mills WD, Davis JT. U.S. Statement of Demonstrated Ability

Colony-forming unit
(CFU) assay is a short-term culture assay used for the detection of
functionally active hematopoietic progenitor cells (HPCs) in the in vitro setting. This potency assay
enables the identification of colony-producing HPCs in any type of
hematopoietic stem cell/progenitor product (HSC/P) including bone marrow (BM),
cord blood (CB) and mobilized peripheral blood (MPB). It has been shown that
the frequency of HPCs in BM, MPB and CB cellular products directly correlates
with the engraftment of both neutrophils and platelets as well as with the
overall survival of recipients following hematopoietic stem cell
transplantation which makes the CFU assay a good quality parameter for the
prediction of engraftment success. The aim of this article is to provide an
overview of different approaches to setting up the CFU assay with an emphasis
on different sample preparation techniques, cell plating density and colony
identification and enumeration used by different laboratories.

The survey consisted of a questionnaire of fifteen questions pertaining to knowledge, awareness and practice of HBV. To further our understanding, the survey was extended to non medical undergraduate students in order to draw a comparable analysis between the general understandings of the viral infection amongst the uninitiated in this field.

RESULTS: The questionnaire was designed with equal number of questions regarding knowledge, awareness as well as practical handling of the disease. The survey was designed in a way which could be understood by population pertaining to medical as well as non medical background. The results of survey depicted statistically significant levels of knowledge, awareness and aptitude for practical handling of the disease. Moreover, comparatively, the level of awareness regarding the infectious disease was vastly lacking among the students of non professional courses.

CONCLUSION: Authors concluded that the students from the medical background may be involved to spread awareness among the general masses.

INTRODUCTION
Dentinal hypersensitivity is a common clinical condition and the treatment outcome is not consistently successful with any particular treatment modalities. Two chief methods of treatment of dentinal hypersensitivity are tubular occlusion and blockage of nerve activity. Clinicians have used many materials and techniques to treat dentinal hypersensitivity. Research has shown that Lasers effectively occlude the dentinal tubules leading to a decrease in dentinal tubule permeability, thus reducing hypersensitivity.

AIM AND OBJECTIVE
To evaluate the efficacy of Diode laser in dentinal hypersensitivity.

MATERIALS AND METHODS
The desensitizing effect of the laser was assessed in a split mouth study. 10 patients underwent the Diode laser therapy. In the test sites effect of laser application was evaluated at 30 sec, 15 mins and 7 days, whereas in the control group sham laser was used with the similar protocol as test side. Pre and post-operative score for sensitivity was recorded on a VAS scale, at 30 sec, 15 mins and 7 days based on response of the patient to the cold air blast.

RESULTS / CONCLUSION
Diode lasers can be used as an effective treatment option for desensitization.

Laser frenectomy of papilla penetrating frenulum- A case report
Authors: Pandey Patel Shruti
Published: November 2019

Aberrant labial frenum attachment hampers function and aesthetics in maxillary anterior region which can be managed by frenectomy or frenotomy using conventional scalpel incisions or Laser. I preferred to use diode laser due to its extremely precise cutting, clear and bloodless operating field, fast ablation, instant hemostasis, predictable tissue response and less posoperative pain due to coagulation effect on small blood vessels and sensory nerve endings reducing the use of analgesics and pre-operative anaesthesia.
I present a case of midline diastema caused by papilla penetrating labial frenulum attachment treated with diode laser frenectomy.

The Efficacy of Tranexamic Acid in the Reduction of Incidence of Dry Socket : Double Blind Study.
Authors: Vadane Ashvini , Garde Janardan
Published: November 2019

Introduction :- “Dry Socket” is the common complication which occur after tooth extraction.“Dry Socket” is also known as “Alveolar Osteitis” ,“Alveolitis” or “Alveolitis sicca dolorosa”. An incidence of Dry socket is at its peak in the fourth decade of life. Tranexamic acid is an antifibrinolytic drug. It is used in surgeries with the risk of heavy blood loss. Objectives :- The purpose of the stated study is to judge the efficacy of “tranexamic acid” regarding the reduction of incidence of dry socket following extraction of mandibular molar tooth , in comparison with a placebo.This study was based on two parameters ( pain and halitosis ) . Materials and Methods :- This was an institutional study.It was double blind type of study which was performed on 60 patients. These patients were indicated for extraction of mandibular molar tooth. Patients of 20 to 40 years of age group were eligible for this study and they were randomly selected. Patients in “Case group” were instructed to take tab. Tranexamic acid 500 mg and “Control group” patients were advised to take Tab. Paracetamol 500 mg, one hour prior to extraction. Postoperatively antibiotics and analgesics were prescribed for both group’s patients. Results :- The present study supported that local and systemic administration of tranexamic acid decreases the incidence of “alveolar osteitis” which is associated with the extraction of mandibular molars. Conclusion :- This study proved that there is decrease in the incidence of alveolar osteitis ,i.e, dry socket, if we use tranexamic acid , locally and systemically in patients undergoing extraction with mandibular molar teeth.

Published: November 2019

Penelitian ini bertujuan untuk mengetahui seberapa besar pengaruh mempelajari Ilmu Perbandingan Agama (IPA) terhadap keimanan seorang muslim. Penelitian berangkat dengan penggunaan metoe kuantitatif. Penelitian memualai dari pendekatan penelitian, melihat populasi dan mengambil sampel secara langsung dari masyarakat. Teknik pengumpulan data, analisis data, analisis lanjut, dan kesimpulan. Penelitian menuju langsung pada masyarakat dikarenakan masih banyak kaum awam yang kurang memahami ilmu perbandingan agama. Sehingga mereka masih kerap mengartikan IPA dengan ilmu yang sesat hingga mendangkalkan keimanan. Berdasarkan penelitian diatas, peneliti akhirnya dapat menyimpulkan bahwa IPA adalah ilmu yang pada dasarnya mempelajari tentang detailnya suatu agama, yang meliputi asal usus agama yang dipelajari, ciri-ciri agama, hingga struktur agama, dengan tujuan mendapat informasi persamaan hingga perbedaan antar agama. Serta hubungan agama satu dengan agama yang lain. Sehingga IPA sangat penting bagi seorang muslim, karena dengan mempelajarinya seorang muslim dapat memahami agama-agama lain selain islam, dapat menghormati agama lain sebab telah mengetahui perbedaan agama secara mendalam. Selanjutnya dapat mengetahui kelebihan agama Islam setelah dibandingkan dengan agama lain, yang dapat dijadikan sebuah wawasan untuk berdakwah.

Tulisan ini merupakan refleksi pemberdayaan bagi pengelola pendidikan dalam menerapkan kebijakan kurikulum pendidikan bagi anak inklusi. Tantangan dan hambatan dalam implementasi pendidikan inklusi menjadi tanggung jawab bersama yaitu pemerintah, dinas pendidikan, kepala sekolah, guru, orang tua, dan masyarakat. Karena itu diperlukan pengelolaan yang komprehensif mulai dari kurikulum, pendidik, tenaga kependidikan, dan sarana prasarana sekolah. Kurikulum di sekolah inklusi harus memperhatikan kebutuhan dasar anak yang beraneka ragam, tidak bisa disamakan kemampuan anak regular dengan anak berkebutuhan khusus sehingga perencanaan pembelajaran yang disusun oleh guru harus dapat mengakomodir hal tersebut.
Entre o religioso e o secular
Authors: Assis Thaís Silva de
Published: November 2019

Este artigo discute um aspecto da dinâmica do campo religioso contemporâneo dentro do qual, apesar da religião continuar a ser um domínio fundamental da sociedade, cada vez mais indivíduos se autoidentificam como “sem religião” ou “espirituais, mas não religiosos”. A proposta é empreender uma análise teórica que, por suspeitar dos usos acadêmicos e leigos das categorias de religião e irreligião, faz da reflexão sobre eles o ponto de partida para discutir as relações entre o que é considerado religioso e o que fica classificado às suas margens. Nesse sentido, o trabalho pretende contribuir com uma problematização sociológica dos processos de definição dos significados e de elaboração das fronteiras entre as noções de religião e espiritualidade.
A legitimidade do direito no contexto dos processos de validação discursiva e da democracia
Authors: Andrade Marcella Coelho
Published: November 2019

O presente artigo, através de uma metodologia teórica e comparativa, analisa o tema da legitimidade do direito, com foco nos processos de validação discursiva e nos espaços de formação do discurso diante do princípio da Democracia. Para abordagem da legitimidade do ordenamento jurídico são utilizados os pontos de vista de Max Weber e Jürgen Habermas, em razão das nuances trazidas pelos referidos autores a respeito do tema. A respeito da ação comunicativa também é feita uma breve abordagem da influência do conceito de poder comunicativo, de Hannah Arendt, no pensamento Habermasiano. Delineiam-se, ainda, os alicerces da Teoria Discursiva do Direito e seus critérios de legitimação, bem como o alcance da razão comunicativa diante do discurso jurídico, paralelamente ao tema da democracia. Conclui-se que os procedimentos dialógicos de elaboração da norma são essenciais para os sistemas democráticos atuais, sobretudo tendo em vista a configuração pluralista das sociedades modernas, mas é essencial a constante avaliação dos espaços de participação existentes, sob uma perspectiva de potencialidade de participação, para que o procedimento discursivo alcance seu intuito de promover normas racionalmente instituídas.

Católicos de esquerda e de direita, ou nem à esquerda nem à direita?
Authors: J. Silva Rei Pedro
Published: November 2019

Alguns estudos recentes em torno da problemática da secularização parecem tomarpor certo um conflito intrínseco entre crenças religiosas e exercício político, constituindo domínios de sentido e acção analiticamente distintos. Porém, à margem da relação conflitual, as relações entre os dois universos ganham particular importância quando apreciamos o caracter heterogéneo de ambos e a sua porosidade. Neste sentido, com a realização do presente artigo pretendemos retomar o debate em torno da problemática da observação do comportamento político dos católicos produzido no âmbito da historiografia francesa, confrontando as teses do dualismo político àquelas do conflito triangular, e equacionando as suas vantagens e desvantagens na observação do universo crente contemporâneo.
