Sustainable development of a domestic enterprise depends on the rational use of all types of resources, which necessitates the transition to an optimal cost management system. The urgency and significance of the cost management problem necessitates a thorough research and the determination of the optimal cost structure. The article proposes a modeling procedure for improvement of accounting and cost management. The article highlights the features of the management and cost optimization procedure based on functional modeling and re-designing of business processes in the context of the process approach chosen by the majority of enterprises.

In order to improve cost management and the activity of the machine-building enterprise, the article proposed the use of the IDEF0 (Integration Definition for Function Modeling business process) modeling methodologies, which reflects the process approach to the formation and identification of business processes of the enterprise.The article proposes to apply a modeling and redesign process for business processes to find reserves for cost reduction and improvement of cost management system, and presents models of cost management and business processes of freight transport of a structural unit of a machine-building plant.

To optimize the costs of the enterprise proposed the use of functional-cost analysis. The content is determined, application of modeling and redesign of business processes is grounded in order to find the reserves of cost reduction. The procedure of using modeling and re-designing of business processes at Ukrainian enterprises is determined.

The practical significance of the results obtained is to improve the accounting and cost management systems, the results of which can be simulated, which will allow planning, forecasting and cost modeling across the entire business processes chain, developing measures for obtaining the desired results for individual operations and, in general, for functional activities, etc.

1) Antecedentes: Las diferentes rutas migratorias que atraviesan el Mar Mediterráneo son consideradas las rutas más mortíferas de 2019. Son varios los organismos que recopilan información sobre estos movimientos migratorios, refugiados y migrantes deben ser asistidos cuando se encuentren en peligro según el Derecho Marítimo y trasladados a un puerto seguro en el cual se respeten sus Derechos Humanos. La OMS resalta que la hipotermia se sitúa entre los problemas de salud más frecuentes en el Mediterráneo seguido de quemaduras y lesiones accidentales. Las muertes por ahogamiento e hipotermia representan más del 50% de los casos según la OIM convirtiendo esta patología en una emergencia sanitaria cuyo abordaje prehospitalario definirá los resultados clínico-asistenciales. 2) Métodos: Revisión sistemática de tipo exploratoria para describir el conocimiento sanitario actual sobre la hipotermia accidental tras inmersión y como el correcto triaje, clasificación del grado de hipotermia y tratamiento influyen en los resultados clínicoasistenciales prehospitalarios. 3) Resultados: El triaje debe ser llevado a cabo por profesionales experimentados en el ámbito marítimo. El tratamiento recibido debe ser acorde al grado de hipotermia que presente el paciente, el cuál será definido por la clínica. Los casos de HA severa y PCR por hipotermia cumplen los criterios para una derivación hospitalaria urgente. 4) Conclusión: La hipotermia accidental es una patología ambiental, se considera una emergencia y tiene unos principios básicos de clasificación, tratamiento y reanimación. Conocer estos principios asegurará un buen manejo prehospitalario del paciente hipotérmico.
Un análisis del proyecto “Mejora del acceso de niños, niñas y adolescentes a los servicios de traumatología ortopédica en el sur de la Franja de Gaza” desde la visión de un traumatólogo (Intervención con Equipos Quirúrgicos Especializados, EQE)
Authors: Noya Álvarez Felipe
Published: February 2020

Se resume la actividad efectuada por el autor, traumatólogo miembro de un Equipo Quirúrgico Especializado (EQE) en un proyecto de Cirugía Ortopédica Infantil en hospitales de la Franja de Gaza. La organización Médicos del Mundo (MdM) es la que implementa el proyecto desde 2015 hasta hoy con varias misiones quirúrgicas. La situación de crisis y conflicto político mantenido en el tiempo en la zona, con estallidos violencia militar repetidos, hacen compleja la implementación del programa. Se pretende hacer una descripción del programa, del modo de trabajo de los EQE de cada misión, y resaltar las dificultades detectadas por los profesionales. Se enumeran los resultados de la actividad efectuada en cuanto a la labor asistencial con los pacientes y de formación y capacitación con los colegas locales. No se pueden entender las dificultades de implementación del proyecto si no se conoce el contexto del bloqueo a las personas y materiales que sufre la Franja, la debilidad de sus estructuras políticas, duplicadas en algunos casos, así como el contexto socioeconómico. Incluso se muestra este ámbito de la patología como poco dimensionada en importancia en términos de salud pública de una población. Las dificultades de movilidad de los profesionales de la Franja de Gaza hacen que tengan casi imposible la actualización y capacitación para el tratamiento de casos complejos. La falta de datos epidemiológicos fiables no permite organizar una respuesta asistencial ad hoc. La multiplicidad de actores en el ámbito asistencial tampoco ayuda a dar una respuesta organizada.

Serial Flaring in an Active Region: Exploring Why Only One Flare Is Eruptive
Authors: Woods Magnus M. , Inoue Satoshi , Harra Louise K. , Matthews Sarah A. , Kusano Kanya
Published: February 2020

Over a four hour period between 2014 June 12–13 a series of three flares were observed within AR 12087. This sequence of flares started with a non-eruptive M-class flare, followed by a non-eruptive C-class flare, and finally ended with a second C-class flare that had an associated filament eruption. In this paper we combine spectroscopic analysis of Interface Region Imaging Spectrometer observations of the Si iv line during the three flares along with a series of nonlinear force-free field (NLFFF) extrapolations in order to investigate the conditions that lead the final flare to be eruptive. From this analysis it is found to be unlikely that the eruption was triggered by either kink instability or by tether-cutting reconnection, allowing the flux rope to rise into a region where it would be susceptible to the torus instability. The NLFFF modeling does, however, suggest that the overlying magnetic field has a fan-spine topology, raising the possibility that breakout reconnection occurring during the first two flares weakened the overlying field, allowing the flux rope to erupt in the subsequent third flare.
Large-scale Dynamics of Winds Originating from Black Hole Accretion Flows. II. Magnetohydrodynamics
Authors: Cui Can , Yuan Feng
Published: February 2020

The great difference in dynamical range between small-scale accretion disk simulations and large-scale or cosmological simulations creates difficulties in tracking the disk wind kinematics. In the first paper of this series, we studied the dynamics of hydrodynamic winds from the outer edge of the accretion disk toward galactic scales. In this paper, we further incorporate magnetic fields by employing a one-dimensional magnetohydrodynamic model, with fiducial boundary conditions set for hot accretion flows. The wind solution is achieved through requiring gas to pass smoothly through the slow, Alfvén, and fast magnetosonic points. Beyond the fast magnetosonic point, physical quantities are found to show power-law dependences with cylindrical radius R, i.e.,

and

. The magnetization of wind is dominant in determining the wind properties. The wind is accelerated to greater terminal velocities with stronger magnetizations. The fiducial parameters result in a terminal velocity of about 0.016c. The dependence of the wind physical quantities on temperature, field line angular velocity, and adiabatic index is also discussed.
Accretion-driven Sources in Spatially Resolved Lyα Emitters

Published: February 2020

Lyα emission is a standard tracer of starburst galaxies at high redshift. However, a number of local Lyα emitters (LAEs) are X-ray sources, suggesting a possible origin of Lyα photons other than young, hot stars, and which may be active at much later ages relative to the parent starburst. Resolved, nearby LAEs offer the opportunity to discriminate between diffuse X-ray emission arising from supernova-heated gas, high-mass X-ray binaries (HMXBs), or low-luminosity active galactic nuclei (LLAGN). We examine archival X-ray imaging from Chandra and XMM-Newton for 11 galaxies with spatially resolved Lyα imaging to determine the luminosity, morphology, and spectral hardness of the X-ray sources. The data are consistent with 9 of the 12, bright Lyα sources being driven by luminous, >

X-ray sources. Half of the eight Chandra sources are unresolved. The data suggest that nuclear activity, whether from LLAGN or nuclear starbursts, may play an important role in Lyα emission. Our results also suggest a significant link between Lyα emission and HMXBs, ultraluminous X-ray sources, and/or LLAGN, which would imply that Lyα may be generated over timescales 1–2 orders of magnitude longer than produced by photoionization from OB stars. This highlights a critical need to quantify the relative contributions of different sources across cosmic time, to interpret Lyα observations and the resulting properties of distant galaxies.
Corps et anticorps. Les grands officiers de Provence durant le règne de Jeanne de Naples (1343-1382), un symptôme du délitement de l’État ?
Authors: Pécout Thierry
Published: February 2020

Le règne de Jeanne I re est considéré comme un moment de délitement de l’État angevin, de ses pratiques administratives, de son emprise juridictionnelle et de son autorité sur les élites. Mais ses méthodes n’ont rien de nouveau, leur généalogie s’enracine dans l’époque de Charles II. C’est une refondation des liens entre État angevin et oligarchies locales qui s’opère dès le règne de Robert et un changement de perspective politique. Pour les domaines provençaux, assez bien documentés (chartrier comtal, registres des officiers, édits de réformation, correspondance avec la papauté), il convient d’examiner plus précisément la mise en place progressive et chaotique de nouvelles relations avec l’oligarchie locale, en particulier les notables urbains. Dans ces nouveaux rapports de force, les grands officiers occupent une place centrale tant par leur milieu d’origine, que par leurs intérêts matériels. Ces derniers sont rivés à une conjoncture économique et démographique qui conduit ce groupe social à reconsidérer ses stratégies, au regard des rentes et revenus qui fondent son hégémonie. L’enjeu est ici de repenser la construction de l’État, en dépassant les taxinomies qui débouchent sur une échelle de valeurs destinée à mesurer leur degré de perfection et d’achèvement.
Meeting Communication Needs: Topics of Talk in the Nursing Home
Authors: Williams Kristine Nordlie , Ilten Teresa Buchhorn , Bower Helen
Published: February 2020

Nursing home residents primarily rely on staff for communication and interpersonal relationships. Challenged by staffing shortages and increasingly complex care, staff who provide the most communication with residents lack awareness and skills to effectively communicate with older adults. This study, a secondary analysis of staff-resident interactions from one nursing home, explored communication topics and the effects of an intervention.

Staff from one unit were recorded during 2 hours of caregiving to provide a representative sample of their communication with residents. Staff then attended an educational program targeting improved awareness of communication needs and reducing “elderspeak.” Recording was repeated post-intervention. Baseline conversations focused on activities of daily living (ADLs), personal-social, technical care, and health assessment. Post-intervention ADL talk decreased in staff-resident interactions, while personal-social topics increased. These findings suggest that residents' limited opportunities for communication with staff are primarily focused on care tasks. With increased communication awareness, staff can learn to modify conversational topics to better meet older adults' psychosocial needs.
Implementing a Smoking Ban in an Acute Psychiatric Admissions Unit
Authors: Matthews Linda S. , Diaz Beth , Bird Paula , Cook Alan , Stephenson Anne E. , Kraus John E. , Sheitman Brian B.
Published: February 2020

In contrast to general medical hospitals, psychiatric hospitals often allow patients to smoke cigarettes. In addition to obvious health concerns, smoking can also interfere with clinical assessments and therapeutic activities. Implementation of a smoking ban on an acute male admissions unit did not result in any increase in aggressive behaviors. In addition, staff attitudes following the ban improved, and most staff members believed the ban was both ethical and beneficial to patients. Our research indicates that banning smoking on an acute admissions unit is feasible and well tolerated by patients and staff, although it may require extra vigilance for smoking-related contraband.

Interpretive Structural Modeling
Authors: Behl Aastha , Pal Abhinav
Published: February 2020

The chapter explains the technique of ISM (Interpretive Structural Modeling) in Multi-criteria decision Analysis (MCDA). ISM is a method to identify inter relationship among various factors pertaining to the authors' research problem. This technique starts with identification of key factors, collected through an extensive literature review of the study. The factors are validated with the help of expert opinions. A pair wise comparative analysis helps in developing a structural self-interaction matrix (SSIM). This is followed by conversion of SSIM to Reachability Matrix, partitioned into different levels. This helps in developing a diagraph, with the help of which an ISM Model is developed. It is also accompanied by MICMAC Analysis which presents a graphical picture of the driving power and dependence power of each factor considered for the study. The chapter would help in understanding the steps involved in the application of ISM technique with the help of hypothetical cases.
Hybrid Multi-Criteria Models
Authors: Efe Ömer Faruk
Published: February 2020

JHSUs should have occupational safety specialists, workplace physicians, and other health personnel to establish and provide services. To provide occupational safety services in the most effective operating environment, it is necessary to select the most appropriate JHSU. This chapter provides a hybrid model to assist the JHSU selection process. Using fuzzy logic linguistic variables makes an important contribution to decision making in uncertain environment. The hybrid model using Fuzzy AHP (Analytical Hierarchy Process) and Fuzzy TOPSIS (Technique for Similarity Sorting Preference for Ideal Solution) approaches were used in JHSU selection. The most important criterion was found to be the references of JHSU. Candidate JHSUs were evaluated on the basis of criteria with fuzzy TOPSIS. Five alternative JHSU were evaluated. Alternative 2 was found to be the most appropriate choice. A numerical example is presented to demonstrate the effectiveness of the proposed hybrid model.
Development of a Charge Estimator for Piezoelectric Actuators
Authors: Mohammadzaheri Morteza , Emadi Mohammadreza , Ghodsi Mojtaba , Bahadur Issam M. , Zarog Musaab , Saleem Ashraf
Published: February 2020

Charge of a piezoelectric actuator is proportional to its displacement for a wide area of operating. Hence, a charge estimator can estimate displacement for such actuators. However, existing charge estimators take a sizable portion of the excitation voltage, i.e. voltage drop. Digital charge estimators have presented the smallest voltage drop. This article first investigates digital charge estimators and suggests a design guideline to (i) maximise accuracy and (ii) minimise the voltage drop. Digital charge estimators have a sensing resistor; an estimator with a constant resistance is shown to violate the design guideline; while, all existing digital charge estimators use one or a few intuitively chosen resistors. That is, existing estimators witness unnecessarily large inaccuracy and/or voltage drop. This research develops charge estimators with varying resistors, fulfilling the design guideline. Several methods are tested to estimates the sensing resistance based on operating conditions, and radial basis function networks models excel in terms of accuracy.

Published: February 2020

The expansion of Cloud computing is influencing various domains such as education, the banking sector, industries, government, health informatics, and individuals. The characteristics of an easy interface, on-demand access, scalability, and low infrastructure investment have to lead to the fast adaptation of Cloud computing based upon their needs. Despite the advantages, Cloud computing is open to more security risks and attacks especially in terms of communication due to the lack of secure authentication and privacy. In this article is presented a novel hash-based multifactor secure mutual authentication scheme that includes mathematical hashing properties, certificates, nonce values, traditional user ids, and password mechanisms that resist MITM attacks, replay attacks, and forgery attacks. We implemented our proposed method in the Microsoft Azure cloud and the results are evaluated. The security analysis is done by using the Scyther tool and with a formal analysis by using GNY belief logic. The results indicate the proposed scheme is capable of providing strong secure authentication.

A survey was carried out to study and collect data about the agricultural farmer injuries of Odisha in India. Five villages with major population with farming as occupation were selected. A total of 145 farmers were selected for the study. It was found that, the number of accidents by hand tools such as spades, plain edge sickles, serrated sickles, and shovels were 13 (16.45%), 6 (7.59%), 11 (13.92%), and 7 (8.86%), respectively. Also, it was observed that maximum number of male and female farmers who were victims of agricultural injury were in the age group of 31 to 45. A smaller number of injured farmers were found in the age group of 18 to 30. Factor analysis followed by the SWARA method was used to rank the important variables which were found as the causes for agricultural accidents or injuries by the responses obtained through questionnaires. Finally, QFD & Interpretive Structural Modeling (ISM) and MICMAC analysis was performed, to frame design requirements in the form of safety requirements.

Smart mobile devices of the present era offer many services i.e. SMS, gaming, a camera, navigation, the Internet, television, etc., and their utilization has significantly risen during the last decades. Today, individuals are addicted to mobiles and cannot think of living without using them. Conversely, these mobiles become obsolete due to certain shortcomings and are eventually replaced with new ones and thus create e-waste, which are alarmed as threat to the society. In this work, the authors describe mobiles and e-waste in a closed loop structure for supporting green issues. The work has rooted generalized interval-valued trapezoidal fuzzy numbers (GIVTFNs) with a degree of similarity measure approach to model the rationale and to furnish decision results. The authors developed a decision support system to prevent e-waste by defining significant inadequacy liable for the larger alteration of working mobiles. The present study demonstrates the technical model under an Indian context to verify its applicability, but it can be used it under any regional or worldwide scenario.
Bibliographic Analysis of Operations Research Citation in the Environmental Domain
Authors: Keenan Peter
Published: February 2020

This article uses bibliographic analysis techniques to examine the papers in the Web of Science database that have citation links to key operations research/management science (OR/MS) journals. The research identified the journals and papers in the environmental domains which cite these OR/MS journals and identify the key journals, papers, and themes. This research shows that environmental disciplines are becoming more important relative to the business and engineering domains that predominated in the previous years. However, much of the citation of OR/MS journals is for techniques like data envelopment analysis (DEA) which are used to conduct research rather than directly model environmental problems. Of the modelling techniques used to address problems in the environmental domains, MCDM methods are the most often cited, reflecting the importance of MCDM with the decision support systems (DSS) field. There are also significant numbers of applications relating to logistics and energy which cite OR/MS papers. Further research is needed to clarify the role of OR/MS techniques in the environmental sector, a domain outside the traditional areas of OR/MS application.

Published: February 2020

The self-efficacy of Brazilian data scientists' professional profiles was analyzed to launch new views on this profession, marked by fast technological changes and with a body of knowledge and an incommensurable scope of skills, as understood by these professionals. A grounded theory was built using a qualitative approach. It found the coping theory to explain the phenomenon after the emergence of self-preservation, as an adaptation strategy, and self-efficacy, as a striking feature of the profession. A practical implication is that self-efficacy has trade-offs both to threats and opportunities in the process of becoming a data scientist. The present article describes the value of the coping theory makes possible an in-depth view of the analytical expertise influence on threats and opportunities, and on technology adaptation choices.
Intent to Leave Versus Intent to Stay in Technology Organizations
Authors: Bello Janine Silva Alves , Steil Andrea Valéria
Published: February 2020

The intention to leave a job and the intention to stay at the job are considered the best predictors of staff turnover or retention. Based on this assumption, this study is aimed at analyzing the relationship between demographic variables (employee age, gender, marital status, kinship responsibility, education level), attitudinal variables (job satisfaction, affective commitment to organization, carrier commitment) and behavioral intentions (employees' intention to leave the job and employees' intention to stay at the job). From June to December 2016, on-line questionnaires were applied to knowledge-intensive organizations employees in Florianópolis, Santa Catarina State, Brazil. This article discusses the results and presents suggestions for further investigation.
Effect of Controlling Parameters of Tone Reservation Based on Null Subcarriers (TRNS) on the Performance of OFDM Systems
Authors: Mounir Mohamed , El Mashade Mohamed Bakry
Published: February 2020

High data rate communication systems usually implement Orthogonal Frequency Division Multiplexing (OFDM) to face frequency selectivity. High Peak to Average Power Ratio (PAPR) is an OFDM disadvantage that causes Bit Error Rate (BER) degradation and out-of-band (OOB) radiation when OFDM signal pass through nonlinear Power Amplifier (PA). In order to overcome this problem larger Input Back-Off (IBO) is required. However, large IBO decreases the PA efficiency. PAPR reduction techniques are used to reduce the required IBO, so that PA efficiency is saved. Several PAPR reduction methods are introduced in literature, among them Tone Reservation based on Null Subcarriers (TRNS) is downward compatible version of Tone Reservation (TR) with small excess in the average power and low computational complexity compared to others. As will be shown, TRNS is the best practical one of the four downward compatible techniques. Performance of TRNS is controlled by three parameters; number of peak reduction tones (PRTs), predefined threshold (Amax), and number of iterations (Itr). In order to increase PAPR reduction gain, enhance BER performance, and reduce the required IBO to follow the given power spectral density (PSD), we have to choose the values of these parameters adequately. Results showed that, we have to reduce the threshold value to the average (i.e. Amax =0 dB). Also, we have to increase number of PRTs. However, we have to maintain the spectrum shape. Finally, we have to choose moderate number of iterations (e.g. Itr ≈50), as excessive increase in number of iterations is not useful, especially at high PAPR values.
