A Classification System and Treatment Guidelines for PAH Associated with Congenital Heart Disease
Authors: Beghetti Maurice
Published: May 2019

Congenital heart defects are among the most common congenital malformations at birth, with an incidence of approximately 8/1000 live births. These defects are characterized by a heterogeneous group of abnormal communications and connections between the cardiac chambers and great vessels with different hemodynamic consequences and hence, varying need for follow-up and interventions. The most common forms are congenital cardiac systemic to pulmonary shunts (ie, ventricular septal defects, atrial septal defects, patent ductus arteriosus) that account for almost 60 % of congenital cardiac malformations.

Pulmonary Vascular Response Patterns to Exercise: Is There a Role for Pulmonary Arterial Pressure Assessment During Exercise in the Post-Dana Point Era?
Authors: Lewis Gregory D.
Published: May 2019

Pulmonary hypertension (PH) is often diagnosed late in its course when it purports a particularly poor prognosis. Exercise effectively unmasks early forms of several cardiopulmonary diseases but the role of performing pulmonary arterial pressure measurements during exercise in the evaluation of PH remains unclear. Whether pulmonary arterial pressure-flow relationships during exercise may provide a window into earlier diagnosis of functionally significant pulmonary arterial hypertension and left ventricular dysfunction or add incrementally to our armamentarium of diagnostic tests and prognostic indicators in PH is the topic of active ongoing investigation. Evidence is emerging that abnormal pulmonary arterial pressure response patterns to exercise, when properly indexed to increased blood flow, may help to identify early forms of heart failure and pulmonary arterial hypertension. This article will discuss approaches to performing hemodynamic measurements during exercise as well as the potential clinical utility of identifying normal and abnormal pulmonary vascular response patterns to exercise.

The Structure of Pulmonary Hypertension Health Care Delivery: Translating Ethical Considerations into Practice
Authors: McGoon Michael D.
Published: May 2019

The ethical imperative to provide optimal care to patients applies not only to individual caregivers, but also to the medical community as a whole. Best care frequently requires a team approach. This is the obvious basis for the common practice of referring a patient from one physician to another for all or part of the patient's management. The incremental benefit may occur by providing specialized knowledge to the medical issue at hand; by contributing a broad second perspective to an incompletely defined clinical problem; by applying particular technical skills; or by facilitating access to an infrastructure of management not otherwise available. Other less obvious advantages may result from referrals, such as reducing for the referring caregiver the intensity of labor involved in managing a complex patient and enhancing the breadth and depth of experience of the referred-to caregiver. This in turn may allow economies of scale to improve efficiency of clinical care, promote knowledge acquisition by observation of multiple cases, and facilitate opportunities for formal clinical research. Many of these issues are particularly relevant for diseases that occur relatively infrequently, especially if management is capable of influencing outcome. Pulmonary arterial hypertension is an example of this category of disease. Are there principles that can be articulated to guide collaboration among caregivers to promote the best possible outcome in the most patients?
Advances in Electrochemistry for Monitoring Cellular Chemical Flux
Authors: Messerli Mark A. , Sarkar Anyesha
Published: May 2019

The transport of molecules and inorganic ions across the plasma membrane results in chemical fluxes that reflect cellular function in healthy and diseased states. Measurement of these chemical fluxes enables the characterization of protein function and transporter stoichiometry, characterization of the viability of single cells and embryos prior to implantation, and screening of pharmaceutical agents. Electrochemical sensors are sensitive and noninvasive tools for measuring chemical fluxes immediately outside the cells in the boundary layer, that are capable of monitoring a diverse range of transported analytes including inorganic ions, gases, neurotransmitters, hormones, and pharmaceutical agents. Used on their own or in combination with other methods, these sensors continue to expand our understanding of the function of rare cells and small tissues. Advances in sensor construction and detection strategies continue to improve sensitivity under physiological conditions, diversify analyte detection, and increase throughput. These advances will be discussed in the context of addressing technical challenges to measuring in the boundary layer of cells and measuring the resultant changes to the chemical concentration in the bulk media.

Published: May 2019

Complex of computer models for study of effectiveness of application of space information facilities was developed for solution the tasks of orbits monitoring and space objects recognition. It is shown, that space information facilities provide minimal breaks in observations and can make a significant informational contribution to the solution of the problem of reducing the required time of orbits determination of space objects, including maneuvering ones on both low and high orbits. Comparative assessments of required time for estimation of space objects orbits parameters for various orbits of space information facilities were obtained. It is also shown, that space systems allow carrying out recognition and control of space objects state more effectively, due to the possibility of their observation from short distances in the optical waveband. Methods of space objects image processing are developed and estimates of their effectiveness are presented. Proposals are given for use of small spacecrafts for monitoring low-Earth-orbit space objects when flying on cross courses.

Authors: Bukhtiyarov D. A. , Gorbachev A. P.
Published: May 2019

The novel realization of printed Yagi-Uda antenna is presented in this paper. Such the aerials are widely used in the modern telecommunication and radiolocation systems. The described method uses the nontraditional center-end-fed in-phase excitation through the hybrid ring two-way power divider. This divider behaves acceptable behavior, when all the lengths and clearances between printed conductors are optimized for Russian dielectric material FAF-4. This material is the successful discovery, when the aerial is excited through the subminiature version A connector that satisfies double-sided printed circuit board realization. The simulation-derived results indicate that the proposed aerial is the fan-beam radiator. This radiator is a good candidate for the use in the novel printed planar equidistant phased arrays for various radio systems including radiolocation, radio-finder arrangements, navigation an so on.

Authors: Minaev V. A. , Korolev I. D. , Mukhortov V. V.
Published: May 2019

The article deals with the issues of integrated assessment of complex technical systems stability functioning in techno sphere and info sphere. It is shown that the concept of cyber stability, including its components such as cyber reliability, noise immunity and cyber survivability are insufficiently investigated and defined. The formal definition is given and the scale with various gradation of cyber survivability is entered. On the example of robotic systems in form of drones two variants of mathematical models of cyber survivability estimation are considered. The first variant is related to the description of drones functioning in the conditions of computer attacks without impact protection systems. The second variant reflects the functioning of drones under the conditions of impacts in the presence of adaptive combined cybernetic protection system. In both variants, two strategies are considered - with minimal and maximum intensity of effects on the drone. It is concluded that proposed in the paper approach enables to evaluate the integrated stability of complex technical systems in the techno sphere and info sphere at the same time.
CONTROLLABILITY AND REPAIRABILITY OF REE REPLACEABLE COMPONENTS WHEN BEING REPAIRED AS PART OF MOBILE SYSTEMS
Authors: Komarov M. V. , Strakhov A. F.
Published: May 2019

The required level of technical readiness of the AD WME pieces which are sophisticated restorable technical systems directly depends upon time duration necessary for restoration of their operability after failures. Restoration of the AD WME component parts operability at their deployment sites is usually performed by an aggregate method, i.e. by replacing faulty replaceable components with serviceable (operable) ones from the operational spare tools and accessories kits or with repaired components (in particular, with the use of the unified mobile organisational repair systems). Promptness of restoring repair of the faulty RCs within the unified mobile organisational repair systems depends upon their controllability and repairability. Due to this, it is required to have lists of controllable and repairable RCs in repair documentation used in case of organisational repair of the AD WME pieces with application of the advanced unified mobile organisational repair systems. The article explains specificity of work with the controllable and repairable REE RCs when performing organisational repair of the AD WME pieces at their deployment sites with application of the uni-fied mobile organisational repair systems.

Increase of numbers and complexity of the tasks performed by the AD WME is ensured by constant REE sophistication. In its turn, ensuring observance of the requirements for maintaining reliability of the AD WME pieces requires improvement of the system of the AD WME maintenance and organizational repair at their deployment sites. Primarily, it is related to improvement of the REE maintenance system. This article considers the issues of development and study of different REE maintenance system models. These studies are aimed at developing a rational option of the effective REE maintenance system which takes into account a set of existing limitations.

The problems of designing a hexapod control system - a mechanism with parallel kinematics, designed for guidance and positioning of instruments and antennas of orbiting satellite platforms are considered. Based on the solution of the extended kinematics problem, the algorithm for controlling linear drives with a kinematic pair of screw-nut and two two-axis hinges is specified. The hexapod control scheme with the spatial load position sensor is given, the feasibility of positional control algorithms is estimated on the basis of the modern domestic element base. The estimation is made by the method of mathematical modeling. An algorithm for adaptive neural network control of a hexapod is proposed. An artificial neural network has been developed, which together with a nonlinear controller regulates the force acting on linear actuators by control error. To assess the quality of hexapod control, a dynamic model of the hexapod control system was created in the simulation package SimMechanics of the MATLAB Simulink system. A description is given of the hardware part of the digital control system-the hexapod control unit).

One of the urgent problems civil and military aviation is providing information support to the crew. Control of the surface below and warnings of dangerous situations and objects are required. This problem is most acute in reduced visibility conditions due to low light conditions, heavy precipitation, fog, smoke or dust. Therefore, the developers of avionics seek to create systems that enable all-weather monitoring of the surrounding space. To solve this problem, modern aircraft on-Board survey systems are equipped with image sensors, both passive and active, working in different spectral ranges. In addition, the use of modern high-precision navigation systems and digital computing technology makes it possible to integrate information about the surface below from multispectral sensors with a priori geospatial data concentrated in digital maps.

Pucang Village was consisted of eruption materials of Merapi Volcano. The relatively high coefficient of permeability of the materials consisting this area caused rainwater to directly infiltrate into the ground. Evaluation of engineering geological conditions was conducted for construction of a detention pond in this area, which had limited water supply for daily activities. The evaluation was conducted on results of a 1:10.000 scale of engineering geological mapping and analyses of 1:10.000 scale of geological disaster maps produced by previous researchers. The engineering geological mapping involved mapping of morphological condition and active geomorphic process, lithological condition, existence of geological structure, and water source location. The evaluation results showed that the proposed location met the land suitability criteria for detention pond construction based on the morphological condition and active geomorphic process, existence of geological structure, and water source location, but did not meet those based on the lithological and vulnerability to Merapi Volcano eruption disaster. Construction of impermeable layer to prevent water seepage into the ground and periodic removal of sediment in the base of the detention pond were suggested to be carried out to keep the detention pond functioning properly.

Published: May 2019

El objetivo de este artículo es evaluar la estructuración de un portafolio con acciones de tres fondos de inversión colectiva del mercado colombiano, basados en el rendimiento del índice Modigliani y Modigliani (M2). La metodología utilizada es un modelo de optimización, cuya función objetivo es minimizar la varianza del portafolio conformado por los tres fondos hasta que se iguale con la varianza del mercado (índice Colcap). Los resultados permiten inferir que la optimización mejoraría el rendimiento de las acciones del fondo Indeacción, al pasar de 7,73% a 9,86% efectivo anual; mientras que las del fondo Fiduacción aumentarían su rendimiento de 5,58% a 27,33% efectivo anual. Se concluye que, ante el mayor nivel de incertidumbre en la economía y las particularidades del mercado colombiano, es relevante que los administradores de portafolios incluyan en sus análisis algunos performances para mejorar sus decisiones.

COMMUNITY SERVICE OF AGRO TOURISM IN SIBETAN VILLAGE
Authors: Krisna Adi
Published: May 2019

The development of tourism in Indonesia in line with the government’s program to promote tourism as an effort to increase foreign exchange outside the oil and fuel sector. One potential alternative which could be developed in the village was agro tourism, which has been started to be developed and many of them were already successfully managed. Rilla, et al (1999) stated that the agro tourism development should be an opportunity for local farmers to increase their income for their family. Two groups that became the partners in this community service were Abian Salak agro tourism farmer group and Kebun Salak agro tourism farmer group in Sibetan village. They were selected as the partner in the activities of this program because they had same problems, namely they had low knowledge in managing their agro tourism and low knowledge in promoting their agro tourism to the public especially for domestic or international travelers who have interest in agro tourism. The solutions that were done by the team to overcome these problems were providing the training of agro tourism management that was attractive and sustainable, assisting the farmer in providing essential facilities to support activities that was offered by agro-tourism as well as their knowledge to take care those facilities, and training the farmer in promoting their agro tourism by using offline media (brochures and joining some activities of tourism festival) and online media (agro-tourism website and the use of social media). The methods that were used in these activities were assisting and training the farmer in managing their agro tourism and promoting them to the costumers. Those problems could be solved and could give a positive impact to the agro tourism management that was attractive and sustainable.

THE COMPARISON BETWEEN AUDITORY LEARNERS AND VISUAL LEARNERS’ ACHIEVEMENT IN WRITING SKILLS OF THE STUDENTS IN THE ENGLISH EDUCATION DEPARTMENT UIN ALAUDDIN MAKASSAR
Authors: Rahim Muthi'ah
Published: May 2019

This quantitative research is aimed to find out (1) the writing quality of both visual and auditory learners; (2) whether or not the writing quality of auditory learners is significantly different from that of visual learners; and (3) which type of learners has better writing quality. This research applied causal-comparative design in analyzing and comparing the writing skills between the visual and auditory learners. The research participants were the sixth semester students of English Education Department UIN Alauddin Makassar in the academic year of 2017-2018. The data were collected using two kinds of instruments, namely Perceptual Learning Style Inventory and writing test. The results showed that both the visual and auditory learners are in normal criteria of writing quality, and also, there is not any significant difference of writing quality between auditory learners and visual learners. Nevertheless, auditory learners had a tendency to outweigh the visual learners in terms of the total score regardless the insignificancy of the difference. On the other hand, the significant difference of the mean score found from the t-test result underscores the ideas that the learning styles and other contributing factors to writing production to satisfy students’ learning are consistent with the theories used in this study. It proves that every individual’s learning preferences differ significantly, and the stronger the preference, the more important it is to provide compatible learning and teaching strategies which involve students’ strategies, knowledge and purposes.

This research aimed to investigate the meaning of enthusiasm, to observe the responses of enthusiastic students to the speaking activities in the speaking class, and to investigate the factors influencing students’ enthusiasm in speaking class. This research belongs to qualitative and it is placed within the phenomenology approach as the collection of information was qualifiedly by examining the phenomena of the factors influencing students’ enthusiasm in speaking class at the 5th semester students of English Education Department at UIN Alauddin Makassar. The data were analyzed and interpreted by using “coding technique” which covered three types: open coding, axial coding, and selective coding. The findings showed that Enthusiasm has several meanings such as; feeling or emotion, excitement, eagerness and achieving. Enthusiasm has several functions like; energy enhancer, goal maintainer, curiosity gripper, interest presenter, fire igniters, fear reducer, worry dissolver, and apathy eliminator. There are eight characteristics of enthusiastic students, they are; happiness, curiosity, satisfaction, endurance in speaking, courage, intolerance, agreement, and assistance. The factors influencing students’ enthusiasm in speaking class are; the instructional materials used by the lecturers or teachers, the lecturer/teacher competence and performance, the students’ attitude during the speaking activities, and the classroom environment.

Root rot caused by Phytophtora capsici is one of the most important root diseases of pepper. The experiment was conducted at Denbiya and Takusa district with aimed to evaluate effective red pepper varieties and types of seed bed against root rot disease. Five red pepper varieties namely Melka Dera, Melka Oli, Melka Zala, Marco Fana, local; and two seed bed types namely flat and raised bed were used as treatments. Treatments were arranged in a factorial combination in RCBD with three replication.  Result showed that the minimum incidence and severity of 28.13 % and 19.8%, respectively was recorded from Melka Oli variety transplanted in a raised bed while the maximum incidence and a severity of 51.03% and 42.8%, respectively were recorded from local red pepper in flat seed bed. The maximum grain yield of 28.81 q/ha and insignificance yield losses were recorded from Melka Oli in raised beds while the minimum grain yield and maximum yield losses 11.12q/ha and 61.44%, respectively were recorded from local red pepper in flat seed bed. Therefore, results suggested that the use of Melka Oli variety transplanted at raised seed bed is promising for significant reduction in root rot incidence and a corresponding increase in yield of red pepper.

Remarkable progress in the field of antibacterial herbal therapy has been made in recent decades in response to the development of drug-resistant pathogens in aquaculture. Studies have focused on the in vitro antimicrobial activity screening of ethanolic extracts of various plants belonging to the genus Ficus. The aim of the present study was to evaluate the antibacterial efficacy of ethanolic extracts of various Ficus species against Yersinia ruckeri. In vitro tests for antibacterial activity revealed that ethanolic leaf extracts of various Ficus species and their cultivars offer a promising alternative to antibiotics and chemotherapeutics for controlling the growth of Y. ruckeri. In our study, ethanolic extracts obtained from leaves of F. natalensis subsp. leprieurii and F. macrophylla proved effective against a bacterial strain at a dose of 400 pl standardized inoculum (108 CFU ml−1). It should be noted that Y. ruckeri demonstrated an intermediate susceptibility to more extracts derived from the leaves of Ficus species. Our investigation showed that among the various Ficus species, ethanolic leaf extracts of ten Ficus species against Y. ruckeri were the most effective. The effect of the leaf extracts that expressed the highest antimicrobial activity (F. macrophylla, F. natalensis subsp. leprieurii) against Y. ruckeri was comparable to that of gentamicin. Therefore, preliminary screening indicated that the ethanolic leaf extracts of some Ficus species with antibacterial properties can be used in aquaculture as therapeutic and prophylactic agents against fish pathogens, including Y. ruckeri.
Evaluation of Outcomes of a Pharmacist-Run, Outpatient Insulin Titration Telepharmacy Service
Authors: Deas Crystal , Stockton Katharine
Published: May 2019

Purpose: Diabetes can pose a significant disease burden for patients and is often challenging to manage in underserved patient populations with limited access to care. A pilot study was conducted to determine the impact of a pharmacist-run insulin titration service, provided via telephone, to patients of a local ambulatory care clinic with a large medically, underserved patient population.  The pilot service was implemented in Spring 2018 at Cooper Green Mercy Health Services (CGMHS) and was provided by an affiliate clinical pharmacist who is also on faculty at Samford University’s McWhorter School of Pharmacy. Patients who received care within the CGMHS diabetes clinic were eligible for referral to the service. The service was provided via a collaborative practice agreement. The purpose of this study was to evaluate and compare clinical outcomes of patients who received the telepharmacy service versus the standard of care.  Standard of care was defined as patients whose insulin therapy was managed solely by the primary care provider or by a diabetes clinic provider, without clinical pharmacist involvement in the patient’s care.

Methods: This manuscript presents the results of a retrospective chart review conducted at CGMHS of patients, ages 19 or older, with a documented diagnosis of type 1 or type 2 diabetes who received care during the timeframe of February 2018 through September 2018 – the initial months of the pilot telepharmacy service.

Results: Sixty-seven patients met criteria for inclusion in the analysis - 16 managed in the telepharmacy service, 28 in diabetes clinic, and 23 in primary care. Patients in the telepharmacy group achieved a mean A1c change of -1.14% compared with -0.88% in the diabetes clinic group and +0.21% in the primary care group (p=0.061). In the telepharmacy group, 43.75% of patients experienced at least a 1% reduction in A1c from baseline compared with 35.71% in the diabetes clinic group and 26.09% in primary care (p=0.51).

Conclusion: Integration of the clinical pharmacy services for insulin titration positively affected patients’ degree of glucose control. Although no statistically significant reductions in A1c were observed in this study, it should be noted that pharmacist intervention was associated with a modestly higher percent A1c reduction from baseline vs. the standard of care. The pharmacist-run service produced changes in clinical outcomes that numerically exceeded those experienced by patients receiving specialty care, in the diabetes clinic, and within primary care.  As a result of this study, the pilot program has remained in effect and is in the initial stages of expansion of the consult service to eligible primary care patients.

Proces rehabilitacyjny św. Joanny d’Arc (1450–1456)
Authors: Kuźba Mariusz

Inkwizycja, która w dużym stopniu determinuje ocenę Joanny d’Arc, rozwijała się przez wieki. Jej procedura prawna miała na celu uniknięcie niesprawiedliwych wyroków. Proces Joanny stanowi przykład licznych uchybień. Anglicy, dla których stanowiła symbol francuskiego oporu, postarali się nie tylko o wyeliminowanie jej z rzeczywistości politycznej, ale i o zniszczenie dobrego imienia (nieuzasadnione rozszerzenie składu sędziowskiego, opłacenie go, wyimaginowane posądzenia). Proces rehabilitacyjny św. Joanny d’Arc jest bezprecedensowym postępowaniem dokumentującym nadużycia. W związku z interwencją samego papieża, do którego apelację uprzednio uniemożliwiono, za sprawą działań króla Karola VII oraz dzięki zeznaniom wielu osób powiązanych z procesem skazującym, oczyszczono dobre imię „Dziewicy Orleańskiej”.
