Konkurencyjność i innowacyjność regionów Unii Europejskiej – analiza porównawcza
Authors: Hamerla Ewa
Published: April 2019

Konkurencyjność to bardzo szerokie pojęcie. Jedni naukowcy wiążą silnie jej definicję z efektywnością ekonomiczną, inni z innowacyjnością, a są również tacy, którzy jej charakter pojęciowy będą uzależniać od otoczenia, w jakim może ona występować na rynku. Konkurencyjność można ująć zarówno w skali mikro(w przypadku pojedynczych przedsiębiorstw czy branż), jak i w skali makro (w tym przypadku będzie się ona odnosić do całych państw). Poziom konkurencyjności jest często uznawany za jeden z podstawowych czynników rozwoju gospodarczego państw (Żbikowski, s. 38 ). Głównym wskaźnikiem mierzącym poziom konkurencyjności regionów i krajów Unii Europejskiej jest indeks RCI (Regional Competitiveness Index). Na jego podstawie możemy wyciągnąć pewne wnioski dotyczące ich rozwoju. Celem niniejszych rozważań jest udzielenie odpowiedzi na pytania o to, jaki jest poziom konkurencyjności poszczególnych regionów Unii Europejskiej oraz w jakim stopniu innowacyjność państw członkowskich Unii Europejskiej wpływa na poziom ich konkurencyjności. W artykule podjęto również próbę ocenienia poziomu rozwoju państw członkowskich na podstawia analizowanych danych.

Published: April 2019

En este estudio se evaluó la remoción de sulfuros en aguas residuales del proceso de pelambre o depilado de pieles, utilizando ozono como agente oxidante. Se determinó el efecto del pH inicial sobre el proceso de remoción, para este fin se usó un diseño experimental completamente al azar, en el cual el pH del agua se varió entre 10, 11, 12 y 13, el ozono fue dosificado a una tasa de 0,5 g h-1 por un periodo de 3 horas tomando muestras cada 30 minutos. Los ensayos fueron realizados para el agua residual real, suministrada por una curtiembre y agua residual sintética, a fin de comparar la remoción alcanzada en cada caso. El análisis de los resultados obtenidos permitió señalar que la mayor remoción se logró a pH 11 en el agua residual real, alcanzando un valor de 77,78%, aproximadamente 39% superior al alcanzado al mismo pH para el agua residual sintética. También se evaluó la cinética del proceso, obteniendo que los resultados se ajustan a una cinética de pseudo primer orden para la cual el coeficiente cinético fue de -0,0001 s-1, por último, se observó que después de cada ensayo se presentó disminución pH, lo cual confirma lo que químicamente debería suceder, formación de H2SO4 por la oxidación de sulfuros a sulfatos. Finalmente, se concluye que la remoción de sulfuros empleando ozono es una técnica aplicable para pH alcalino, permitiendo reducir tiempos de oxidación y convirtiéndose en una alternativa viable para aplicar en la industria del curtido de pieles.
HERMENEUTIKA INSIDER-OUSIDER; STUDI ATAS PENGARUH HEREMENEUTIKA BARAT TERHADAP HEREMENEUTIKA ISLAM

Published: April 2019

Salah satu kekayaan khazanah intelektual Islam adalah peninggalan Kitab-kitab tafsir klasik yang ditulis oleh sarjanawan dan mufassir muslim ternama. Jumlahnya sangat mengagumkan, mengingat setiap mufassir dalam menafsirkan al-Qur’an melahirkan Kitab yang berjilid-jilid. Namun seiring dengan kemunduran umat Islam, khususnya dalam bidang pengetahuan, kuantitas (bahkan mungkin pula kualitas) volume tafsir tersebut mengalami penurunan tajam. Ditengarai salah satu penyebabnya adalah tertutupnya pintu ijtihad, sehingga masyarakat umum hanya mengikuti eksegesi yang telah dikembangkan dan digariskan oleh ulama’.

Penelitian ini mencoba mencari tahu tentang bagaimana perubahan secara fonemis pembentukan kosakata serapan bahasa Arab dalam bahasa Minangkabau (Padang, Sumatera Barat).  Kemudian adakah perubahan makna yang terjadi dengan adanya proses fonologi dan morfologi terhadap kosakata serapan bahasa Minang dari Bahasa Arab. Peneliti menggunakan metode agih dalam menganalisis data. Metode agih menurut Sudaryanto adalah metode analisis yang alat penentunya terdapat pada bahasa itu sendiri, dengan cara substitusi. Metode agih digunakan untuk menentukan pergeseran kata Bahasa Arab dalam bahasa Minangkabau. Selanjutnya dalam menganalisis hasil penelitian, penulis melibatkan dua bahasa; dengan demikian, penelitian ini juga menggunakan metode padan translasional. Pada tataran fonologis kosakata serapan bahasa Minang yang terambil dari bahasa Arab, beberapa fonem bisa diserap secara utuh dalam artian sesuai dengan transliterasi Arab-latin, namun ada juga yang tidak diserap secara utuh seperti fonem ف, karena fonem ini bukan diserap dengan menggunakan fonem /f/ dalam bahasa Minang namun diserap dengan /p/. Pada tataran morfologis dan semantik, beberapa perbedaan ditemukan antara bahasa Arab dan bahasa Minang. Sekalipun kosakata serapan bahasa Minang tersebut diambil dari bahasa Arab, namun urutan huruf dan kata terkadang tidak serupa. Begitu pula mengenai makna kata dalam bahasa Minang yang merupakan serapan dari bahasa Arab mengalami penyempitan dan perluasan, namun tidak sedikit juga yang tidak mengalami perubahan makna.

Authors: Awad Mohammedziyad Abu
Published: April 2019

Type2 diabetes is estimated to affect 380 million people worldwide in 2025. Patients of this disease are at increased risk of cardiovascular diseases (CVD).The CVD risk is greater when diabetic patients have metabolic syndrome. Thus, the management of metabolic syndrome and CVD is crucial for diabetic patient’s life progress. GLP-1 has positive biological influences on glucose metabolism control by inhibiting glucagon secretion, enhancing insulin secretion and protecting the effects of cells. GLP-1 was also found to have other positive influences including weight loss, appetite sensation and food intake. These are important factors in metabolic disturbances control and CVD management. The paper reviewed several studies regarding the GLP-1 positive concerns. In conclusion, the paper supports the modern proposal of GLP-1 RAs as a first line therapy in initially diagnosed type 2 diabetes patients.
Doctors as a Part of Nutrition Care of Patients (Srinagar, Jammu and Kashmir)
Authors: Masoodi Nayera , Seth Veenu , Singh Kalyani
Published: April 2019

Doctor’s main role and prior responsibility is medical treatment of patients. Doctors can also share their expertise in nutrition care of patients in hospitals. Optimum nutrition affects both the response to medical treatments and eventually recovery. Doctors are usually perceived as the best source of information, by patients. In addition, they must provide some nutrition information to patients, in order to provide good care to patients. Doctors can motivate patients to eat healthy and also guide patients for dietary modifications to help in recovery. The present study, exploratory in nature, was carried out in Srinagar to have an insight and know the role and perspective in patient care especially in context of nutrition services, in the hospitals. The objective of the study was to investigate about if doctors were a part of nutrition care. Study sample consisted of 62 doctors, representing 2% from each hospital. Data was gathered using an interview schedule followed by observation and discussion with doctors. A scoring pattern was formed to evaluate doctor’s perspective and their role in nutrition care of patients. Data was collected from 11 hospitals which provided nutrition services to patients which were included in the study. It was seen that doctors appeared to have a minimal role and little awareness of the assessment of nutritional needs of patients. Doctors reported that they briefly discussed the diet with some of their patients. Nutritional assessment was not done during the patients hospital stay. Their interaction with dietitians was also not adequate about patients nutrition care. It was concluded that there was a need to increase the awareness of doctors about the importance of nutrition care of patients. However what was encouraging was the response of the doctors towards the need for dietitians, providing a balanced diet and nutrition counselling, perhaps indicating some realization that dietitians were required for improving nutrition care of patients.
Vitamin B12 Status among Healthy Indian Population: A Review
Authors: Malik Anku , Kumar Geeta Trilok
Published: April 2019

Vitamin B12 is a water-soluble micronutrient found in animal foods. Its deficiency is not uncommon in India owing to vegetarianism but often unrecognized due to diverse clinical manifestations, involving hematologic and behavioral and neurologic deterioration. The present review is to collate the current data on vitamin B12status among healthy Indian population. A total of 620 studies were identified using PubMed, out of which 40 studies that matched the selection criteria, were shortlisted and reviewed. The results highlight inadequate vitamin B12 status in most age groups, with the prevalence of deficiency reaching 100%, 78.5%, 61.7% and 75.4% in infants, children and adolescents, adults, elderly and pregnant women, respectively based on varying cut offs. However, due to variation in the biomarkers and cutoffs used for defining clinical and sub-clinical vitamin B12 deficiency and varied laboratory techniques used for analysis, direct comparison of the prevalence of deficiency in the studied population is difficult. Nevertheless, this review highlights that vitamin B12 deficiency is an emerging public health concern that requires further research involving dietary intake of vitamin B12 and serum levels in population groups in India to understand many aspects of vitamin B12 absorption, bioavailability and metabolism.

Authors: Kumar Arun , Srinivasan V , Kavle R , Sharma R , Gariya B. C. , Panda D
Published: April 2019

PY-1 is one of the few fields in India producing hydrocarbons from Fractured Basement Reservoir. The field was developed with nine slot unmanned platform with gas exported through a 56 km 4" multiphase pipeline to landfall point at Pillaperumalnallur. Field was put on production in November 2009 with three extended reach wells.

The production performance of the field had some surprise and declined earlier than expected. As a result, based on the conclusions drawn from an integrated subsurface study, a two wells re-entry campaign to side track wells Mercury and Earth was planned to be executed in Q1 2018.

The objectives of this paper are twofold:Review the production performance of a granitic basement gas field and share learnings which may be useful for similar fields being developed elsewhere.Share the fit-for-purpose modelling workflow adopted to identify the opportunities and estimate reserves

Methods, procedures, process

The workflow consisted of following:Key uncertainties impacting GIIP and recovery were ascertained through subsurface and production data analysisAnalytical reservoir engineering tools such as material balance was used to estimate GIIP from production and pressure analysis. Importance of having PDG installed in offshore wells with unmanned platforms are highlighted.The uncertain petrophysical parameters such as porosity and was constrained based on GIIP estimates from material balanceProsper models were used to understand and predict the well performance and optimal tubing size to avoid liquid loadingFit-for-purpose simulation models were constructed to quantify impact of key uncertainties on production forecast and recovery

In order to mitigate the operational risks, drilling services were outsourced as a turnkey project to an industry leading service provider.
Automated Core Fracture Characterization by Computer Vision and Image Analytics of CT Images
Authors: Antle Ryan
Published: April 2019

Computer vision (CV) techniques were applied to X-ray computed tomographic (CT) images of reservoir cores to evaluate their potential for rapidly identifying fractures and other lithologic/geologic characteristics. The analyses utilized feature-labeled CT cross sectional images, themselves distributed submillimeter voxels of density- and atomic number-sensitive CT Numbers, as inputs to a Fully Convolutional Neural Network (FCN) for semantic segmentation of reservoir core features. In FCN, an image is interrogated using a series of sliding windows at various scales to create weighted filters to reduce error between classes in training images. These networks of filter layers were used to assign probabilities of classes, which were upscaled back to the original image dimensions resulting in probabilistic class assignments onto each pixel. FCN model accuracy, defined by its ability to replicate manually-assigned labels in the raw (unannotated) training image stack, was at least 80% and generally improved with the size of the training set. Once the labels were assigned, the underlying feature frequency, orientation, and size were measured in 3D volume reconstructions using algorithms modified from standard image analysis software. This method allowed users to endow a classification model with subject matter knowledge for further, autonomous label prediction. Thus, while initial image annotation was labor intensive, subsequent images were rapidly classified once the model was built. The classified labels were analyzed for abundance, orientation, and size of fractures were calculated to characterize spatial information of these features. FCN combined with fracture labeling improved knowledge capture and automation of fracture identification. Models trained by high quality 3D datasets can greatly reduce the time needed to describe subsequent core. The method demonstrated is not limited to fractures, other lithologic/geologic features could be trained using the same method, which may result in additional efficiencies.
Gas Huff and Puff Process in Eagle Ford Shale: Recovery Mechanism Study and Optimization
Authors: Wang Leizheng , Yu Wei
Published: April 2019

US unconventional resource production has developed tremendously in the past decade. Currently, the unconventional operators are trying many strategies such as refracturing, infill drillings and well spacing optimization to improve recovery factor of primary production. They are also employing big data and machine learning to explore the existed production data and geology information to screen the sweet spot from geology point of view. However, current recovery factor of most unconventional reservoirs is still very low (4~10%). A quick production rate decline pushes US operator to pursue gas EOR for unconventional reservoirs, lifting the ultimate recovery factor to another higher level. The goal of this work is to improve oil recovery by implementing gas Huff and Puff process and optimizing injection pattern for one of the US major tight oil reservoirs - Eagle Ford basin. Gas diffusion is regarded as critical for gas Huff and Puff process of tight oil reservoirs. Utilizing the dual permeability model, gas diffusion effect is systematically analyzed and compared with the widely used single porosity model to justify its importance. Transport in natural fractures is proved to be dominated recovery mechanism using dual permeability model. Uncertainty studies about reservoir heterogeneity and nature fracture permeability are performed to understand their influences on well productivity and gas EOR effectiveness. Moreover, three alternative gas injectant compositions including rich gas, lean gas and nitrogen are investigated in gas Huff and Puff processes for Eagle Ford tight oil fractured reservoir. The brief economic evaluation of Huff and Puff project is conducted for black oil region of the Eagle Ford basin.

Published: April 2019

Failures due to solid particles flowing with the production fluid is one of the main causes of interventions in wells with beam pumping systems. When this problem is accompanied with chemical deposition like scale, leads to a very common intervention during well operation. This paper proposes an analytical methodology that consists of evaluation of the particle size distribution, viability for the use of sand screens and centrifugal separation systems for sand control management in wells with short run time. These systems have proven effective for failure wells that requires a sand control management system when if not addressed increase the lifting costs leading many projects to be infeasible from an economic standpoint. All the technical considerations are explained focusing on the information required and the parameters analyzed to recommend the most accurate design for sand control; selected approaches and models that have been developed to improve the run time due to sand issues are shown in this paper.

A case study is showed in a well with average run time of 27 days indicating that identification of particle size distribution was a key factor to provide the right solution for sand control management. These novel applications help operators to reduced OPEX (operating expense), by minimizing well Interventions, decreasing failures in the pump; stabilizing the production and reducing the unforeseen interruption.
Reservoir Characterization Using NMR Data in Absence of Core - Breakthrough in NMR Data Utilization
Authors: Vij Jitesh , Nandi Anindya , Singh Sachit , Majumdar Chandan , Haldia Bhopal Kumar , Chaturvedi Praveen Chandra , Sarkar Sutanu
Published: April 2019

Considering the modern oil price environment, oil companies are more pressured than ever to reduce costs. This need affects tools used for reservoir characterization. Coring is important but expensive and is usually not available for the entire length of the well. A novel methodology is presented to perform reservoir characterization from wireline nuclear magnetic resonance (NMR) data, in the absence of any core, in offshore gas-bearing wells. This includes computing T2 cutoff, hydrocarbon saturation, permeability, and poro-fluid sand facies determination.

NMR is a shallow measurement and using wireline NMR measurements is even more challenging due to higher time after bit and increased mud filtrate invasion. Consequently, its use is restricted to quantifying porosity, and even the basic assessment of bound/free fluid require correct T2 cutoff to be determined from cores. Traditional formation evaluation methods use various equations like Archie’s, dual water, Waxman Smits, etc. to determine hydrocarbon saturation, all of which have many variables which, again, must be determined from cores. This makes it imperative to have core measurements to get precise results.

In this paper, we present the results of successful implementation of the proposed methodology, which functions without core data. It employs NMR data along with modern processing techniques like factor analysis and fluid substitution, and integrates density data to evaluate reservoir by 1) minimizing the mud signal, 2) using the virgin zone data to extract dominant peaks and repeated patterns on T2 distribution to divide the entire reservoir section into different poro-fluid types, 3) obtaining the T2 cutoffs for various poro-fluids facies, 4) calculating density magnetic resonance porosity (DMRP) and adopting it to drive fluid substitution, 5) obtaining original water equivalent porosity which is divided by DMRP to get water saturation, 6) employing the fluid substituted (water-only equivalent) T2 distribution along with the T2 cutoff determined by factor analysis to calculate permeability using the Timur-Coates equation.

Authors: Hazra Suchandra , Madrid Vanessa , Luzan Tatiana , Van Domelen Mark , Copeland Chase
Published: April 2019

This paper provides a detailed evaluation of the impact that field source water chemistry has on the performance of friction reducers being used for hydraulic fracturing. In this research, correlations are established between friction reducer performance and source water chemical composition, allowing operators to shorten the learning curve within their fracturing operations, use the most appropriate fluid systems, and potentially mitigate job failures.

Extensive testing has been conducted to evaluate friction reducer performance in the presence of different ionic components such as calcium, magnesium, iron and chloride. Performance testing was determined by varying individual ions, as well as using source waters from multiple field locations having total dissolved solid (TDS) levels of well over 100,000 ppm. Testing parameters included friction reduction, hydration rate via viscosity, and rheological characterization for viscosifying-type friction reducers. Principal component analysis was used as statistical tool to characterize the variation in water chemistry and to establish its relationship with friction reducer performance.
Extension of Oil Well Economic Life by Simultaneous Production of Oil and Electricity
Authors: Wang Kai , Wu Xingru
Published: April 2019

Oil production decline and excessive water production are prevalent in mature fields and unconventional plays, which significantly impact the profitability of the wells and result in costly water treatment and disposal. To seek for a sustainable development of those wells, reducing the operation cost and extending their economic lives, this paper presents a method of synergistic production of hydrocarbon and electricity, which could harvest the unexploited geothermal energy from the produced water and transfer heat to electricity in the wellbore. Such method is cost-effective, since it does not require any surface power plant facility, and it is replicable in numerous wells including both vertical wells and horizontal wells. By simultaneous coproduction of oil and electricity, the value of existing assets could be fully developed, operation cost could be offset, and the economic life of the well could be extended.

This recently proposed method incorporated thermoelectric power generation technology and oil production. In this method, electricity could be produced by thermoelectric generator (TEG) mounted outside of the tubing wall under temperature gradient created by produced fluid and injected fluids. The aim of this paper is to illustrate the economic practicability of oil-electricity coproduction by using thermoelectric technology in oil wells based on previously proposed design. We examined the technical data of high water-cut oil wells in North Dakota and collected required information with respect to performance thermoelectric power generations. Special emphasis was placed on the key parameters related to project economics, such as thermoelectric material, length of TEG and injection rate. Sensitive studies were carried out to characterize the impact of the key parameters on project profits. We showed that by simultaneously production of oil and electricity, $234,480 of additional value could be generated without interfering with oil production.

The proposed method capitalizes on the unexploited value of produced water and generates additional benefits. This study could provide a workflow for oil and gas operators to evaluate an oil-electricity coproduction project and could act as a guidance to perform and commercialize such project to balance parts of the operation cost and extend the life of the existing assets.

Published: April 2019

Optimization problems, such as optimal well-spacing or completion design, can be resolved rapidly via surrogate proxy models, and these models can be built using either data-based or physics-based methods. Each approach has its strengths and weaknesses with respect to management of uncertainty, data quality or validation. This paper explores how data- and physics-based proxy models can be used together to create a workflow that combines the strengths of each approach and delivers an improved representation of the overall system. This paper presents use cases that display reduced simulation computational costs and/or reduced uncertainty in the outcomes of the models. A Bayesian calibration technique is used to improve predictability by combining numerical simulations with data regressions. Discrepancies between observations and surrogate outcomes are then observed to calibrate the model and improve the prediction quality and further reduce uncertainty. Furthermore, Gaussian Process Regression is used to locate global minima/maxima, with a minimal number of samples. To demonstrate the methodology, a reservoir model involving two wells in a drill space unit (DSU) in the Bakken Formation was constructed using publicly available data. This reservoir model was tuned by history matching the production data for the two wells. A data-based regression model was constructed based on machine learning technologies using the same dataset. Both models were coupled in a system to build a hybrid model to test the proposed process of data and physics coupling for completion optimization and uncertainty reduction. Subsequently, Gaussian Process Model was used to explore optimization scenarios outside of the data region of confidence and to exploit the hybrid model to further reduce uncertainty and prediction. Overall, both the computation time to identify optimal completion scenarios and uncertainty were reduced. This technique creates a robust framework to improve operational efficiency and drive completion optimization in an optimal timeframe. The hybrid modeling workflow has also been piloted in other applications such as completion design, well placement and optimization, parent-child well interference analysis, and well performance analysis.
Comparison between Wedge Resection and Segmentectomy for Ground Glass Opacity-dominant Early Stage Non-Small Cell Lung Cancer (TSCI 002): Study protocol for a randomized controlled trial
Authors: Liao Hu , Pang Long , Ma Lin , Liu Chengwu , Pu Qiang , Mei Jiandong , Lin Feng , Liu Lunxu
Published: April 2019

Background: Currently, there are no universally recognized criteria to choose between segmentectomy and wedge resection. However, compared with segmentectomy, wedge resection is more accessible, less invasive, preserves more pulmonary tissues and presents a faster post-operative recovery process, which in turn, result in a higher quality of life. We hypothesize that wedge resection could be a potential alternative to anatomic segmentectomy for patients with very early non-small cell lung cancer (NSCLC), and we plan to conduct the first randomized trial comparing the effectiveness and safety of wedge resection and segmentectomy to guide the surgical decision.
Methods: We plan to conduct a prospective, multicentre, randomized, open, parallel control and non-inferiority verification adopted study. Patients from 21 sites of China who satisfy all the inclusion criteria and do not fall into any of the exclusion criteria are qualified to be included in this study. They will then be randomly allocated into two groups: lung wedge resection + hilar and mediastinal lymph node resection / sampling (study group) and segmentectomy + hilar and mediastinal lymph node resection/sampling (control group). A recruitment period of no more than two years is anticipated. The primary endpoint of the study is 5-year disease-free survival (DFS) between the two groups. The secondary endpoints are 3-year DFS, 5-year overall survival （OS）, 30-day morbidity and mortality rates, and pulmonary function.
Discussion: This is a multi-centre, randomized, open, parallel control, and non-inferiority verification adopted study to evaluate whether lung wedge resection and segmentectomy are equivalent in long-term oncological efficacy in patients with ground glass opacity (GGO)-dominant early stage peripheral non-small cell lung cancer.

Authors: Diriba Kuma , Kassa Tesfaye , Alemu Yared , Bekele Sisay
Published: April 2019

Background: Ocular disease with its complications is a major public health problem which significantly impacts on quality of life in developing countries. An ocular infection due to microbial agents, can lead to reduced vision and blindness. This study was aimed to assess the antimicrobial susceptibility pattern and biofilm forming potential of bacteria isolated from suspected external ocular infected patients attending Jimma University Medical Center (JUMC).
Method: A cross sectional facility based study was conducted on 319 suspect patients with external ocular infections from March 2017 to June 2017 at JUMC in Southwest Ethiopia. External ocular specimens were collected and standard operating procedures were followed to handle and culture throughout the study period. Antimicrobial susceptibility pattern of the isolates was determined by disk diffusion method according to CLSI 2015. Microtiter (96 wells) plate method was used to screen biofilm formation by measuring optical density at 570nm.
Result: Out of 319 study participants with external ocular infection, the prevalence of bacterial pathogens was 46.1%. The predominant bacterial isolates were Coagulase negative staphylococcus (CoNS) (27.7%) followed by Staphylococcus aureus (19.7%). Among Gram negatives, Pseudomonas aeroginosa (6.8%) was the leading isolate. Increased antimicrobial resistance was observed for tetracycline (64%), erthromycin (66.7%) and penicillin (77.1%). Amoxicillin-clavulanic acid, ciprofloxacin and gentamicin were the most effective drugs for both Gram negative and Gram positive ranging from about 70 to 100% with the later two drugs for external ocular infections. Methicillin resistant S. aureus (MRSA) accounted for 13.8% of S. aureus isolates.. Multidrug resistance (MDR) accounted for 68.7%. The overall biofilm formation rate of bacterial ocular pathogens was 66.1%; with P. aeruginosa (40%), CoNS (34.1%) and S. aureus (31%) formed strong biofilm phenotype.
Conclusion: The prevalence of bacterial isolates among external ocular infection was high. Almost all bacterial isolates were resistant to atleast one or more drugs. MDR pathogens were observed increasingly among biofilm formers or vice versa. Therefore, antimicrobial susceptibility testing should be practiced to guide treatment of external ocular cases and to control the emergence of drug resistant bacteria.
Interplay between Infarction Volume and Location to Mediate the Occurrence of Vertigo in patients with Vertebrobasilar Stroke

Published: April 2019

Background

Vertigo is a common presentation of cerebellar or dorsal brain stem infarctions. However, the relation between infarction volume and the development of vertigo in patients with vertebrobasilar stroke was never investigated. In this study, we aimed to examine the interaction between the infarction size and location on the development of vertigo in patients with vertebrobasilar stroke.

Methods

Fifty-nine consecutive patients presenting with vertebrobasilar stroke were recruited and stratified into the presence or absence of vertigo. National institute of health stroke scale (NIHSS) on admission as well as modified Rankin Scale (mRS) and Barthel-index on discharge were used as clinical scales. The infarction location and volume were assessed in the diffusion-weighted images of magnetic resonance imaging (MRI).

Results

The infarction volume did not correlate with NIHSS-score on admission (ρ=0.077, p=0.56) but correlated with mRS (Spearman ρ=0.37, p=0.004) and Barthel index on discharge (ρ=0.33, p=0.011), serum levels of HbA1c (ρ=0.3, p=0.02) as well as white blood cells (ρ=0.34, p=0.008). Patients with vertigo had less male predominance (53.1% versus 77.8%, p=0.049) and were less likely to have focal neurological manifestations (65.6% versus 96.3%, p=0.004) in comparison to those without vertigo. The median of the total infarction volumes were statistically significant larger among patients with vertigo (5.6 versus 0.42 cm3, p=0.008). In an age and sex adjusted multivariate binary logistic regression model, an infarction location either in the cerebellum or dorsal midbrain and a total infarction volume of >0.48 cm3 were found to have an OR (95% CI) of 16.97 (3.1-92.95), p=0.001 and 4.4 (1.05-18.58), p=0.043, respectively to be associated with vertigo.

Conclusion

In addition to the infarction location in the cerebellum and/or dorsal brain stem, it seems that the infarction volume plays a role in the development of vertigo among patients with vertebrobasilar stroke. In patients with vertebrobasilar stroke, increased serum levels of HbA1c and leukocytosis seems to mediate the development of large infarctions.

The objective of the study: to compare the clinical and X-ray signs of tuberculosis in HIV positive and HIV negative children, to identify factors that are more common in HIV infected children in the region with a high prevalence of both infections. Subjects and methods. 264 children with tuberculosis, and 41 children with HIV infection and tuberculosis undergoing inpatient treatment were enrolled in the study, which was the retrospective study of medical records. The patients underwent standard clinical and X-ray examinations, and microbiological tests. Results. Disseminated forms of tuberculosis (39.1%), tuberculous meningoencephalitis (4.9%) were more frequent in the HIV positive children, while in HIV negative children, it made 1.9 and 0.4% respectively. Among HIV positive children, 34% had several sites of tuberculosis, and 19.5% suffered from generalized forms. In HIV positive children, tuberculosis was more often detected in the infiltration phase, it was accompanied by severe intoxication symptoms, while when taking anti-tuberculosis therapy in combination with ART, they had more rapid positive changes.

Evaluación de sostenibilidad en proyectos de desarrollo
Authors: Hernández Medina Carlos Alberto , Báez Hernández Alexander , Carrasco Fuentes Magdalys Alibet
Published: April 2019

El desarrollo sostenible es un proceso permanente y una búsqueda perpetua de balance entre las demandas generadas para satisfacer las necesidades humanas y la capacidad de la Naturaleza para cubrirlas sin degradarse. Como en los proyectos hacia la sostenibilidad no se conoce el estado final, los procesos necesarios, ni los tiempos, eso lleva a la necesidad de utilizar procesos iterativos en que se repiten continuamente los pasos como una espiral de planificación, monitoreo y evaluación, en lugar de los procesos lineales. El monitoreo y evaluación de proyectos se concentra en el análisis de su desempeño y de sus impactos en forma regular a lo largo de su vida a fin de ir ajustando y refinando el trabajo del Proyecto sobre la marcha.

The main problem of the research is development of a conceptual framework for investment and innovation security, as well as the methodological approach to its assessment, which will allow monitoring and identifying the threats and achieving the desired security state of the national economy. It has been proved that investment and innovation security is a multi-level phenomenon, consisting of the following levels: global, national, corporate and household ones. Investment and innovation security is determined by three components, such as state security at the external and internal markets, security of enterprises (corporations) and individual households, which requires their balancing. The methodical approach to the integrated assessment of the investment and innovation security level is developed, which involves the development of integral index as the geometric mean of 3 sub-indices, which include single indices under the national, corporate and household level. The results of this methodological approach approbation allowed us to form preconditions for finding ways of growth, forecasting trends and building scenarios for strengthening the investment and economic security of Ukraine.
A videófelvétellel támogatott felidézés alkalmazása a nemzetközi pedagóguskutatásokban
Authors: Szivák Judit , Nagy Krisztina , Gazdag Emma
Published: April 2019

A pedagógusok reflektív gondolkodásának feltárására – más módszerek mellett – széles körben elfogadott és alkalmazott kutatási módszer a videófelvétellel támogatott felidézés (VSR). Korábbi tanulmányunkban (Neveléstudomány, 2018/3.) szisztematikus irodalomfeldolgozásunk alapján bemutattuk, hogy a VSR alkalmazása milyen változatos kutatási célokat szolgál, és milyen eredményeket hoz nemzetközi térben, jelen tanulmányunkban pedig a VSR módszertanának bemutatására vállalkozunk. Az irodalmi áttekintés tanulságai azt mutatják, hogy a VSR eljárást a pedagógusok reflektív gondolkodásának kutatásában többnyire kis mintán végezték, és kevert kutatási metódus keretében (a kutatás megbízhatósága, érvényessége és a módszertani trianguláció érdekében) további módszerekkel: az interjúval (Haggarty, Postlethwaite, Diment, & Ellins, 2011; Mak, 2011), a kérdőívvel (Freitas, Jiménez & Mellado, 2004), a reflektív naplók különböző típusaival (Stanulis, 1995; Yerrick & Hoving, 2003), a hangosan gondolkodással (Allison, 1990), az osztálytermi megfigyeléssel (Freitas et al., 2004; Gunckel, 2013), az esetmegbeszéléshez társított egyéb módszerekkel, például a gondolattérképpel (Näykki & Järvelä, 2008), valamint óratervek (Girotto Júnior & Fernandez, 2013), illetve videófelvételek (Stanulis, 1995; Zimmerman, 2015) elemzésével, feldolgozásával együtt alkalmazták a kutatók. A VSR a hozzá társított más módszerekkel együtt alkalmasnak bizonyult a pedagógusok és pedagógushallgatók gondolkodási mintáinak, osztálytermi döntéseinek, pedagógiai fejlődésének megismerésére és fejlesztésére.

Időskorúak nyelvtanulói autonómiájának fejlesztése tanulás-módszertani tanácsadással
Authors: Schiller Emese , Dorner Helga
Published: April 2019

Tanulmányunk az időskorúak nyelvtanulói autonómiájának tanulás-módszertani tanácsadáson keresztül történő fejlesztési lehetőségeit mutatja be. Az időskori tanulást befolyásoló belső, illetve külső tényezők bemutatása mellett a tanulmány célja, hogy a szenior korúak hatékony oktatásával foglalkozó szakirodalmat is bemutassa. Az időskorú tanulók autonóm viselkedésének kialakítására és annak támogatására alkalmas módszer a tanulás-módszertani tanácsadás, amely számos, egymásra épülő módszertani elemet tartalmaz. A tanulással kapcsolatos nehézség konkretizálásától a célkitűzésen, valamint az autonóm tanulást befolyásoló egyéb tényezők megismerésén keresztül megy végbe. A folyamat lezárása a tanulási folyamat egészére való reflektálás. A tanácsadás az időskorúak esetében az eddigi negatív tanulási tapasztalatok felülírására, tanulói motivációjuk támogatására, a nyelvtanulási stratégiák tudatosítására és az időskorúak tanulással töltött idejének hatékony megszervezésére fektet hangsúlyt. Végezetül megfogalmazunk olyan kutatási kérdéseket, amelyek az időskorúak tanulás-módszertani tanácsadásának mélyebb, empirikus úton történő megismerését szolgálhatják.
