Published: June 2017

O diagnóstico das lesões intraepiteliais e do carcinoma do colo uterino é realizado mediante a associação de três métodos, que são a citologia, colposcopia e histologia. O presente estudo representa uma pesquisa epidemiológica transversal retrospectiva e descritiva de prontuários de pacientes com achados citológicos e colposcópicos, compatíveiscom a infecção por HPV, atendidas na clínica Potengi, no ano de 2012 (Natal, RN). Foram analisados 111 prontuários de pacientes diagnosticadas com HPV e os dados coletados foram idade, menarca, início da vida sexual, estado civil, parceiros sexuais, métodos contraceptivos utilizados e resultados de exames citológicos, colposcópicos e histopatológicos. As pacientes tinham média de idade 30 anos, sendo a maioria casada (71,2%), com menarca aos 12 anos e início da vida sexual com aproximadamente 17 anos, com média de parceiros de 9,4. Aproximadamente 38% fazia uso de anticoncepcional oral, 37% não fazia uso de qualquer método e apenas 10% fazia uso de preservativo. O percentual de concordância entre citologia e colposcopia e entre a citologia e histologia foi bastante significativo (rs=0,953; p<0,05). A partir da análise do presente estudo, pode-se concluir que a associação dos métodos citológicos, colposcópicos e histológicos apresenta maior eficiência no diagnóstico de lesões causadas por vírus como o HPV e carcinoma, devendo, portanto, serem usados em conjunto.
A meta-analytic perspective on school climate studies in Turkey: The impact of some demographic variables
Authors: Sönmez Emre , Sezgin Ferudun
Published: June 2017

The purpose of this study is to analyze teachers' perceptions of school climate by gender and branch and have an overall idea on this issue. Meta-analysis method was employed in this study. Master's theses and doctoral dissertations as well as academic articles published in peer-reviewed journals dwelling on teachers' views on school climate in Turkey were analysed through various databases. A total of 30 studies meeting the criteria for inclusion in the study were included. In the analysis of research data, a random effects model was used. Results indicate that gender has no significant influence on the dimensions of disengagement, directiveness, and supportiveness of school climate, but has a significant influence on the dimensions of restrictiveness and intimacy. Gender was seen to have a significant but low influence on restrictiveness in favour of male teachers and on intimacy on behalf of female teachers. According to the study results, branch does not have a significant influence on the dimensions of school climate except for disengagement. Branch was seen to have a significant but low impact on disengagement in favour of subject teachers. In this sense, it was concluded that superficial variables like gender and branch do not have any determining influence on teachers' perceptions of school climate. Therefore, it may be recommended for researchers to study more primary factors concerning school climate.

Published: June 2017

Staphylococcus aureus (S. aureus) is the most common agent of contagious mastitis that causes serious health and economic problems. The ability to form biofilms is an important virulence factor of S. aureus for the establishment of persistent infections. This study is aimed to investigate the presence of icaA and icaD, two genes of importance for the biofilm formation in S. aureus bovine mastitis isolates. In order to isolate and identify S. aureus, 1555 milk samples were collected from 401 cows, located in different regions of the Republic of Serbia. Using the conventional microbiological methods 100 isolates were characterized as coagulase-positive staphylococci. After primary biochemical identification, the species confirmation of 44 S. aureus isolates was done using MALDI-TOF Mass Spectrometry and PCR technique, targeting the S. aureus-specific nuc gene. Among all investigated S. aureus isolates 25.0% harbored both icaA gene and icaD genes. The presence of icaD gene alone was confirmed in 40.9% of cases totaling icaD positive isolates to 65.9%. The remaining 34.1% of S. aureus isolates were negative for the presence of both genes. The results of the present study indicate the existence of potential biofilm-producer strains in different regions of the Republic of Serbia, both under intensive and semi-extensive cows breeding.
Variation in the Course and Termination of the Cephalic Vein in the Deltopectoral Triangle
Authors: Dogood Atoni Atoni , Aidemise Oyinbo Charles
Published: June 2017

The knowledge of cephalic vein variation would aid proper identification and prevent error in surgical emergencies. The path, distribution, and termination of the cephalic vein in relation to the deltopectoral triangle were studied in twenty formalin-embalmed cadavers.

Results show the bilateral presentation of the cephalic vein in all the shoulders examined. Thirty-seven (37) cases presented with a superficial and lateral course of the cephalic vein in the deltopectoral groove, while the rest three cases presented a deep course. Of these 37 cases with the superficial course, two cases ascended anteriorly and above the clavicle and drained into the external jugular vein in the neck. Another case presented a cephalic vein that ascended anteriorly and then above the clavicle and drained into an unnamed vein in the neck. In one case, the cephalic vein ascended superficially in the deltopectoral groove and laterally in the deltopectoral triangle. In one bilateral pattern, the cephalic vein in the deltopectoral triangle drained into the axillary vein. In all the three cases where the cephalic vein ascended deep within the deltopectoral groove, they terminated deep in the deltopectoral triangle. In one of these, the cephalic vein received a tributary that originated from a venous network beneath the deltoid muscle and then drained into athe xillary vein, deep in the deltopectoral triangle. In the other two cases, the cephalic vein gave a tributary to the axillary vein and continued deep and medially in the deltopectoral triangle, passed below the clavicle and drained into the subclavian vein.

The knowledge of these variations of the cephalic vein is essential to clinicians and surgeons for venous access during emergencies and surgery.

Authors: Baghdari Nasrin , Rad Mostafa , Sabzevari Marzie Torkmannejad
Published: June 2017

Due to the diversity of midwives’ responsibilities, the skill to deliver bad news is a vital need, and therefore the teaching approach in this matter is of utmost importance. Thus, this study has been conducted with the purpose of comparing the effect of SPIKES-based education of skills needed for delivering bad news, using two different approaches of role playing and multimedia in midwifery students.

This double-blind clinical trial was done on 90 midwifery students who were randomly assigned to three separate groups. Students’ skill in delivering bad news was recorded through a specific checklist before and after the educational intervention. The reliability and validity of this skill evaluation checklist was assessed and confirmed. The final data were analyzed using SPSS software.

After educational intervention, role playing and multimedia groups have gained more skills compared to their previous conditions as well as the control group. The skill of delivering bad news did not show a significant difference in role playing and multimedia groups after intervention.

The results showed that teaching the skills of delivering bad news using multimedia approach which was held as distance learning course would rival active educational methods such as role playing. Thus, it could be a suitable replacement for role playing methods in increasing the skill needed for delivering bad news.

Authors: Kozomara Slavica , Krstić Ivana
Published: June 2017

Cardiac rehabilitation is an integral part of the complex therapy of cardiac patients.

The aim of this study was to determine the effect of dynamic exercise and dynamic resistance training on exertion tolerance, muscle strength of the upper and lower extremities, and respiratory index in patients after surgical coronary revascularization.

The study included 84 patients divided into two groups. Both groups of respondents were included in the complex cardiac rehabilitation program of the interval type. In the first group, the patients performed dynamic exercise. The second group of patients received a combination of dynamic exercise and dynamic resistance training.

At the end of the rehabilitation treatment, which lasted 21 days, a statistically significant difference in muscle strength of the upper and lower limbs was observed in both groups (p < 0.05); statistically significant difference was found in relation to exertion tolerance in both groups (p < 0.001); a statistically significant difference in duration of exercise stress test was observed in the both groups (p < 0.05); respiratory index values showed statistically significant differences in both groups (p < 0.001).

After the rehabilitation treatment, in both groups of patients there were statistically significant differences in increasing the muscle strength of the upper and lower extremities, exertion tolerance, and respiratory index; however, beneficial effects of physical training were more pronounced in the group of subjects included in the program of resistance exercise for the upper and lower extremities.

In the present article, magneto-micropolar nanofluid flow with suction or injection in a porous medium over a stretching sheet for the heat and mass transfer is analyzed numerically. Both Hall and ion-slip effects are considered along with variable thermal diffusivity. The governing partial differential equations are transformed to ordinary differential equations using usual similarity transformations. These coupled non-linear differential equations are solved using the shooting method. Effects of prominent parameter on velocities, temperature and concentration are discussed graphically. Numerical values of skin-friction coefficient, local Nusselt number and local Sherwood number are also tabulated and discussed.
Regulation of the Dynamic Live Load Factor for Calculation of Bridge Structures on High-Speed Railway Mainlines
Authors: Dyachenko Leonid K. , Benin Andrey V.
Published: June 2017

When the high-speed railway traffic is being organized, it becomes necessary to elaborate bridge design standards for high-speed railways (HSR). Methodology of studying the issues of HSR bridge design is based on the comprehensive analysis of domestic research as well as international experience in design, construction and operation of high-speed railways. Serious requirements are imposed on the HSR artificial structures, which raise a number of scientific tasks associated mainly with the issues of the dynamic interaction of the rolling stock and the bridge elements. To ensure safety of traffic and reliability of bridges during the whole period of operation one needs to resolve the dynamic problems of various types of high-speed trains moving along the structures. The article analyses dependences of the magnitude of inertial response on the external stress parameters and proposes a simplified method of determination of the dynamic live load factor caused by the passage of high-speed trains. The usefulness of the given research arises from the reduction of complexity of the complicated dynamic calculations needed to describe a high-speed train travelling along the artificial structures.
Optimal Shakedown of the Thin-Wall Metal Structures Under Strength and Stiffness Constraints
Authors: Alawdin Piotr , Liepa Liudas
Published: June 2017

Classical optimization problems of metal structures confined mainly with 1st class cross-sections. But in practice it is common to use the cross-sections of higher classes. In this paper, a new mathematical model for described shakedown optimization problem for metal structures, which elements are designed from 1st to 4th class cross-sections, under variable quasi-static loads is presented. The features of limited plastic redistribution of forces in the structure with thin-walled elements there are taken into account. Authors assume the elastic-plastic flexural buckling in one plane without lateral torsional buckling behavior of members. Design formulae for Methods 1 and 2 for members are analyzed. Structures stiffness constrains are also incorporated in order to satisfy the limit serviceability state requirements. With the help of mathematical programming theory and extreme principles the structure optimization algorithm is developed and justified with the numerical experiment for the metal plane frames.
Inference for copula modeling of discrete data: a cautionary tale and some facts
Authors: Faugeras Olivier P.
Published: June 2017

In this note, we elucidate some of the mathematical, statistical and epistemological issues involved in using copulas to model discrete data. We contrast the possible use of (nonparametric) copula methods versus the problematic use of parametric copula models. For the latter, we stress, among other issues, the possibility of obtaining impossible models, arising from model misspecification or unidentifiability of the copula parameter.
Kant’s ethics as practical philosophy: On philosophy of freedom
Authors: Belás Ľubomír
Published: June 2017

The paper focuses on some important philosophical issues of Kant’s philosophical legacy, especially on Kant’s thoughts on man and his acting in community with other human beings, his fellows, (Conjectural Beginning of Human History) from the aspect of morality based on moral-practical terms and categories. The field of Kant’s practical-critical thoughts is not only unusually broad but also full of ideological dynamics offered in a precise and modern linguistic form. The paper claims that Kant offers his own answer for the fourth question “Was ist der Mensch” (“What is man?”), introduced in Logic (Kant, 1992, p. 538) and at the same it also introduces a historical dimension to the issue of man, included in his short writings, in a compact form.
Nurses in Poland — Immediate Action Needed
Authors: Haczyński Józef , Skrzypczak Zofia , Winter Małgorzata
Published: June 2017

The aim of the study is to analyse changes in the size of the population of nurses in Poland in the years 2004-2014, considering changes in their employment and the phenomenon of ageing. The analysis is based on the data published by the Central Register of Nurses and Midwives of the Central Statistical Office (GUS) and the Organisation for Economic Co-operation and Development (OECD). Nurses are the largest professional group in the healthcare sector. In 2014, only above 70% of licensed nurses were professionally active. The percentage of employed nurses compared to the number of licensed nurses varied between the lowest ratio of 65.1% in 2005 and the highest ratio of 71.7% in 2012. The latest ratio of 2014 was 70.9%, which was slightly lower compared to the highest ratio in 2012. The average age of a Polish nurse in 2008 was 44.19 years, increasing by about six years to 50.1 within the analysed period. The population of nurses aged above 65 years is almost 4.5 times bigger compared to the youngest age group, which is 21-25 years. Thus, 2/3 of the population of nurses are 41-60 years of age and nearly 85% are over 40. For two years (2000 and 2014), the number of practising nurses per 1000 inhabitants places Poland in the fifth bottom position among the European countries, which shows a significant reduction in patient access to nursing services. In Poland, the profession of nurses has no replacement generation. The article presents the shortage of professionally active nurses in Poland. The existing register of nurses does not contain complete information necessary to evaluate the current situation in Poland. There is a strong need to improve the tracking system of the register of nurses to accurately monitor the number of nurses in Poland The shortage of professionally active nurses and their ageing necessitates immediate action to reduce the shortage by increasing the appeal of the profession among young people and by encouraging nurses to return to the profession. It is also necessary to take action to delay the retirement of those nurses who want to work longer and to use their potential. This is also particularly important because of the gap in experience, which is going to become apparent the nearest future.
Criteria for Geo-Environmental Evaluation of Prospective Areas of Mineral Deposit Occurrence
Authors: Sikorska-Maykowska Małgorzata , Walentek Iwona , Andrzejewska-Kubrak Kamila
Published: June 2017

In this work, we present the problem of geo-environmental assessment of prospective areas of mineral deposits occurrence in Poland. T he issue is discussed mainly based on data from the database of Geo-environmental map of Poland, scale 1:50 000 (MGśP II). While for proven deposits a classification based on environmental conditions has been used for many years, for prospective areas of mineral occurrence such an assessment is not conducted. Taking into consideration not only protection of the natural environment, but also protection of mineral resources in Poland, it is necessary to review the approach to areas with prospective mineral resources from the point of view of their role in land use planning. Such prospective areas have - depending on the type of mineral in question, how large an area has been prospected, its geological structure - highly diverse surface area, from just a few to thousands of hectares. T his means the approach to environmental assessments of prospective areas of mineral occurrence must be different from that for already proven locations of mineral resources. The article presents quantitative characteristics of prospective areas of mineral occurrence presented on the aforementioned MGśP II map for Poland. We propose herein criteria for environmental evaluation of such prospective areas, differentiating them mainly depending on the type of mineral, manner of exploitation, surface area and land use legal forms, as well as possibility of future reclamation.

Authors: Aldret Randy L , Trahan Brittany A , Davis Greggory , Campbell Brian , Bellar David M
Published: June 2017

The purpose of this study was to determine the appropriateness of using an elastic hamstring assistance device to reduce perceived levels of soreness, increase isometric strength, increase passive range of motion, and decrease biomarkers of muscle damage after eccentric exercise, specifically, downhill running This study was conducted in a university exercise physiology laboratory placing sixteen apparently healthy males (X= 21.6 ± 2.5 years) into two groups using a pre-test/post-test design. Pre-intervention measures taken included participants’ body height, body mass, body fat, capillary blood samples, VO2max, isometric hamstring strength at 45 and 90 degrees of flexion and passive hamstring range of motion. Post-intervention measures included blood biomarkers, passive range of motion, the perceived level of soreness and isometric strength. An analysis of normality of data was initially conducted followed by multivariate analysis of variance (MANOVA) of hamstring strength at 45 and 90 degrees of flexion, blood myoglobin and passive range of motion of the hamstrings. Statistically significant changes were noted in subject-perceived muscle soreness and isometric strength at 90 degrees at the 24-hour post-exercise trial measure between the two groups. Results would suggest the findings could be explained by the decrease in muscle soreness from utilizing the device during the exercise trial. Further research should be conducted to address sample size issues and to determine if the results are comparable on different surfaces.
LARGE Estimation of the stress-strength reliability of progressively censored inverted exponentiated Rayleigh distributions
Authors: Kohansal Akram
Published: June 2017

Based on progressively Type-II censored samples, this paper deals with the estimation of R = P(X < Y) when X and Y come from two independent inverted exponentiated rayleigh distributions with different shape parameters, but having the same scale parameter. The maximum likelihood estimator and UMVUE of R is obtained. Different confidence intervals are presented. The Bayes estimator of R and the corresponding credible interval using the Gibbs sampling technique are also proposed. Monte Carlo simulations are performed to compare the performances of the different methods. One illustrative example is provided to demonstrate the application of the proposed method.
Organisational Pathologies Under Conditions of Economic Downswing
Authors: Pasieczny Jacek
Published: June 2017

The topic of organisational pathology is surprisingly absent in literature on management, especially when bearing in mind the theoretical and practical import of such questions. The intention of the author is to fill in this gap, at least partially. The paper is based on an analysis of literature and an empirical research conducted by the author. The research applied partially structured interviews as its method. These interviews were conducted with entrepreneurs and managers of various levels. They made possible the drawing of conclusions relating to conditions behind the genesis and growth of selected organisational pathologies in a situation of economic downswing. The article briefly presents the concept and influence of pathology on the functioning of an organisation. The author concentrates on the causes of the phenomenon and presents them from various perspectives. It is during times of economic downswing that an increase in unethical behaviour, including corruption, mobbing as well as others, becomes particularly visible. Also noticeable is concentrating on limiting costs, which can sometimes reach pathological scale. This can lead to a permanent loss of pro-development potential by the organisation. Moreover, numerous pathological phenomena emerge at the tangent point of the organisation and its surroundings. The source of many undesirable phenomena in the organisation and in its relations with its surroundings is a fall in trust, which makes its appearance in crisis situations. More often than not, managers facing a situation in which they have no choice perpetuate organisational pathologies, whilst, at the same time, being aware of the lack of validity of their actions. However, a more frequent source of problems is the differences in perspective in perceiving organisational phenomena by various actors and stakeholders.
The combined exposure to intra-amniotic inflammation and neonatal respiratory distress syndrome increases the risk of intraventricular hemorrhage in preterm neonates
Authors: Oh Kyung Joon , Park Jee Yoon , Lee JoonHo , Hong Joon-Seok , Romero Roberto , Yoon Bo Hyun
Published: June 2017

Objective:

To evaluate the impact of combined exposure to intra-amniotic inflammation and neonatal respiratory distress syndrome (RDS) on the development of intraventricular hemorrhage (IVH) in preterm neonates.

Methods:

This retrospective cohort study includes 207 consecutive preterm births (24.0–33.0 weeks of gestation). Intra-amniotic inflammation was defined as an amniotic fluid matrix metalloproteinase-8 concentration >23 ng/mL. According to McMenamin’s classification, IVH was defined as grade II or higher when detected by neurosonography within the first weeks of life.

Results:

(1) IVH was diagnosed in 6.8% (14/207) of neonates in the study population; (2) IVH was frequent among newborns exposed to intra-amniotic inflammation when followed by postnatal RDS [33% (6/18)]. The frequency of IVH was 7% (8/115) among neonates exposed to either of these conditions – intra-amniotic inflammation or RDS – and 0% (0/64) among those who were not exposed to these conditions; and (3) Neonates exposed to intra-amniotic inflammation and postnatal RDS had a significantly higher risk of IVH than those with only intra-amniotic inflammation [odds ratio (OR) 4.6, 95% confidence interval (CI) 1.1–19.3] and those with RDS alone (OR 5.6, 95% CI 1.0–30.9), after adjusting for gestational age.

Conclusion:

The combined exposure to intra-amniotic inflammation and postnatal RDS markedly increased the risk of IVH in preterm neonates.

Acquisition of adverbs and pronominal adverbs in a Czech child
Authors: Chejnová Pavla
Published: June 2017

This article addresses the acquisition of adverbs in a Czech monolingual boy from speech onset until age 6. This study is based on an analysis of authentic material: a corpus of transcriptions of audio recordings of the child in verbal interaction with adults, and diary records. The acquisition sequence and adverbial type frequency were analysed. The boy acquired adverbs of place first; although direction was acquired before location, location became more frequent. Adverbs relating to time were developed second, and location in time and repetition were the most frequent temporal aspects. Adverbs of degree followed; adverbs related to high degree were more frequently expressed than adverbs related to low degree. Adverbs of manner appeared last, in which adverbs related to a broader evaluative sense prevailed. Adverbs related to cause were manifested mostly by the interrogative proč / why. Interrelation between the acquisition of nominal and verbal categories was found: when the child acquired the category of nominal case and was able to use the construction of preposition + noun, the percentage of adverbs of place decreased. When he acquired the verbal aspect, the percentage of adverbs related to time decreased.

La vitalidad de una lengua depende de sus hablantes, pero ¿qué sucede cuándo los  hablantes deciden ya no hacer uso de ella? En este artículo se reportan los primeros resultados del análisis realizado a entrevistas de hablantes bilingües ¾náhuatl-español¾, de la comunidad de San Miguel Canoa, en el Estado de Puebla en México; en donde más del 60% de su población reporta conocer la lengua náhuatl (INEGI, 2010) y al mismo tiempo manifiesta que los usuarios activos de la lengua se encuentran en hablantes mayores de 25 años. El análisis de este trabajo: Teoría de la valoración; (Martin & White, 2003; Eggins, 2005; Matthiessen, 2013 ), muestra una significativa correlación entre la pérdida de la lengua náhuatl y la valoración que hacen los hablantes de la misma.

Relaxin (RLN) is a key hormone of pregnancy in mammals best known for its involvement in connective tissue remodeling. In the domestic dog, placental RLN is the only known endocrine marker of pregnancy. However, knowledge is sparse regarding the spatio-temporal expression of RLN and its receptors (RXFP1 and RXFP2) in the canine uterus and placenta. Here, their expression was investigated in the pre-implantation uterus and utero-placental compartments (UtPl) at selected time points during gestation: post-implantation, mid-gestation, and at normal and antigestagen-induced luteolysis/abortion. Immunohistochemistry with newly generated, canine-specific antisera,in situhybridization and semi-quantitative PCR were applied. In compartmentalization studies, placental and endometrialRLNincreased continuously toward prepartum. The placentalRXFP1was time-related and highest during post-implantation and decreased together withRXFP2at prepartum luteolysis. The endometrial levels of both receptors did not vary greatly, but myometrialRXFP2decreased from mid-gestation to prepartum luteolysis. Antigestagen treatment resulted in suppression ofRLNin UtPl and decreasedRXFP1andRXFP2in the uterus. The placental RLN was localized mainly in the cytotrophoblast. Additionally, RXFP1 stained strongly in placental endothelial cells while RXFP2 was found mainly in maternal decidual cells. Uterine staining for all targets was found in epithelial cellular constituents and in myometrium. Finally, besides its endocrine functions, RLN seems to be involved in auto-/paracrine regulation of utero-placental functions in dogs in a time-dependent manner. New insights into feto-maternal communication was provided, in particular regarding the localization of RXFP2 in the maternal decidual cells, implying functional roles of RLN during the decidualization process.

One of the most powerful ways to develop hypotheses regarding the biological functions of conserved genes in a given species, such as humans, is to first look at what is known about their function in another species. Model organism databases and other resources are rich with functional information but difficult to mine. Gene2Function addresses a broad need by integrating information about conserved genes in a single online resource.

Diabetes mellitus is a major health problem in the world. The total number of diabetic’s population is increasing every year. Currently used treatment of diabetes mellitus type 1 by controlling the blood sugar levels, doesn’t prevent complications which associate diabetes. The stem cell based therapy for diabetes aims to replace the diseased or lost cells of the pancreas with new cells using pluripotent or multipotent stem cells. Scientists successfully produced insulin secreting cell from different types of stem cells. In this article we briefly reviewed the progress made in the stem cell research for diabetes treatment.
The Role of Genetic Counseling in Pompe Disease After Patients Are Identified Through Newborn Screening
Authors: Atherton Andrea M. , Day-Salvatore Debra ,   on behalf of the Pompe Disease Newborn Screening Working Group
Published: June 2017

An important part of the coordinated care by experienced health care teams for all Pompe disease patients, whether diagnosed through newborn screening (NBS), clinical diagnosis, or prenatal diagnosis, is genetic counseling. Genetic counseling helps families better understand medical recommendations and options presented by the patient’s health care team so they can make informed decisions. In addition to providing important information about the inheritance and genetic risks, genetic counseling also provides information about Pompe disease and available treatments and resources and should be offered to families with an affected child and all adults diagnosed with Pompe disease. Although the need for genetic counseling after a positive newborn screen for Pompe disease is recognized, the role that genetic counseling plays for both families of affected patients and health care teams is not fully understood. Consistent best genetic counseling practices also are lacking. The guidance in this article in the “Newborn Screening, Diagnosis, and Treatment for Pompe Disease” supplement is derived from expert consensus from the Pompe Disease Newborn Screening Working Group. It is intended to help guide genetic counseling efforts and provide a clear understanding of the role for families or carriers of Pompe disease identified through NBS; explain special considerations (eg, diagnosis of late-onset Pompe disease before the appearance of symptoms) and the impact and implications associated with a diagnosis (eg, determination of genetic risk and carrier status and preconception counseling); and provide health care teams caring for patients with a framework for a standardized approach to genetic counseling for patients and at-risk family members.

Published: June 2017

This paper aims to examine the epistemology of thematic Qur’anic interpretation. The main characteristic of thematic Qur’anic interpretation that can answer questions comprehensively is rare. The focus of this paper is how to implement the holistic epistemology of thematic Qur’anic interpretation to be a source of reference in Qur’anic interpretation. Analytical study of thematic analysis on Qur’anic thematic epistemology conducted by researchers of Qur’anic studies offered a new term that is a holistic epistemology of Qur’anic interpretation. The formulations of its epistemology explained in table 1.2 and table 1.3 in the paper. This paper shows the correlation of the thematic tafsir with many issues occurred in reality. This concept argued to be a solution in a dialogical relation between text and context and give the solution to the problem faced in Muslim society.

Cell-free extracts of six strains of Enterococcus species obtained from fermented foods were used for the green synthesis of silver nanoparticles (AgNPs), which was characterized by UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The biosynthesized AgNPs were dark brown in colour having surface plasmon resonance in the range of 420-442 nm. The spherical shaped AgNPs had sizes of 4-55 nm, whose formations were facilitated by proteins as indicated by the presence of peaks 1,635-1,637 and 3,275-3,313 cm-1 in the FTIR spectra. The energy dispersive x-ray (EDX) showed prominent presence of silver in the AgNPs colloidal solution, while the selected area electron diffraction was typified by the face-centred crystalline nature of silver. The particles inhibited the growth of multi-drug resistant clinical isolates of Escherichia coli, Klebsiella pneumoniae and Proteus vulgaris, and also potentiated the activities of ampicillin, ciprofloxacin and cefuroxime in the AgNPs-antibiotic synergy studies. In addition, the prospective relevance of the particles as nanopreservative in paints was demonstrated with the inhibition of growth of Staphylococcus aureus, Pseudomonas aeruginosa, Aspergillus niger and A. flavus in AgNPs-paint admixture. This report further demonstrates the green synthesis of AgNPs by strains of Enterococcus species.

Reduction in the quality of fruits during storage has been a concern to the consumers and the effect can be felt on the economy of developing countries. Leaves of plants such as Canna indica, Megaphrynium macrostachyum and Thaumatococcus daniellii have been documented as food packaging materials in West Africa. Based on this, the quality of stored sweet orange juice was investigated using ethanolic extracts of leaves of C. indica, M. macrostachyum and T. daniellii to enhance the shelf life of the juice. The extracts were used to assess the quality of juice for 30 days using quantitative parameters such as total soluble solid, browning potential, pH, microbial analysis and turbidity at 4 oC and at room temperature (27-31 oC). The qualitative and quantitative phytochemical constituents of the extracts were determined. The extracts’ toxicity was determined using Brine shrimp. The quality assessment evidently revealed that the freshly squeezed orange juice with the extracts possess tolerable activity to enhance the shelf life of orange juice. The leaf extract of M. macrostachyum had the highest preservation rate on the juice after 30 days. The qualitative phytochemical screening revealed the presence of alkaloid, tannin, saponins, flavonoids, steroids and terpenoids in the three plants tested. The quantitative phytochemical analysis of the most active extracts in the three plants revealed that M. macrostachum had the highest contents of alkaloids (107.48 mg/g) and flavonoids (56.92 mg/g).The study showed that the extracts were non-lethal on Brine shrimp. This study ascertained the potential preservative qualities of the test plants for enhancing the shelf-life of orange juice.

Resumo A eficiência adquiriu maior relevância entre as organizações no cenário de mercados abertos, que teve início no Brasil por volta dos anos 1990. O objetivo deste artigo foi analisar, por envoltória de dados com bootstrap, a eficiência dos aeroportos brasileiros, utilizando as bases de dados da Agência Nacional de Aviação Civil (ANAC) e da Empresa Brasileira de Infraestrutura Aeroportuária (INFRAERO) de 2010, 2011 e 2012. Uma regressão múltipla foi utilizada para validar as variáveis do modelo proposto. Nesse modelo, a medida utilizada para representar o desempenho dos aeroportos foi a quantidade de passageiros processados (variável dependente); para as variáveis que determinam o desempenho (variáveis independentes) foram utilizados: número de pistas, número de balcões de check-in, número de estacionamento de aeronaves e área de passageiros. A partir de então, a técnica Análise Envoltória de Dados foi aplicada para os 16 aeroportos internacionais brasileiros, em abordagem operacional. Para corrigir os valores de eficiência encontrados, tendo em vista o erro aleatório inerente aos dados, aplicou-se uma abordagem da técnica de bootstrap. Os resultados encontrados apontam que a grandeza de um aeroporto não foi determinante para atribuir eficiência, embora seja critério relevante para impulsionar melhorias no seu desempenho. Convém salientar, também, que a utilização dos recursos (inputs) para o alcance do produto (output) foi o critério mais relevante na busca do bom desempenho e da eficiência aeroportuária no estudo aqui apresentado. Nesse sentido, o aeroporto de Curitiba, na Região Sul do país, foi classificado como o mais eficiente em todos os períodos, e os aeroportos do Galeão (Rio de Janeiro) e Manaus (Amazonas) como os menos eficientes.
