Authors: Sandu R. B. , Pantiru M. I. , Cosman M. , Poeata I.
Published: September 2019

“Chiari zero malformation” is a rare and a relatively new described condition which associates syringohydromyelia without caudal displacement of the cerebellar tonsils through the foramen magnum. We present a case of a 40 years old woman with Chiari zero malformation with both syringomyelia and syringobulbia and a good clinical and radiological outcome after posterior fossa decompression. The presence of associated syringomyelia and syringobulbia in this condition is less frequent and it usually occurs in younger patients. In our case we considered syringobulbia as being an extension of syringomyelia.

Published: September 2019

Le travail alimentaire est déterminant dans l’activité des assistantes maternelles. D’une part, il constitue un espace dans lequel se construit la relation et la confiance entre les professionnelles et les parents et, d’autre part, il contribue à la socialisation présente et future de l’enfant. Cet article propose d’explorer le travail alimentaire et ses contraintes organisationnelles, de même que les processus normatifs à l’oeuvre dans la délégation éducative qui s’expriment à l’intérieur du travail alimentaire et de ses modalités de négociation. En dépit d’une faible valorisation de ce travail, voire d’une invisibilisation, l’alimentation est un domaine important de la profession.
GC-MS studies to map mechanistic aspects of photolytic decomposition of pesticides
Authors: Kiss Attila , Virág Diána
Published: September 2019

Transformation of pesticides in the environment is a highly complex process affected by different factors. Both biological and physical-chemical factors may play a role in the degradation, whose ratio depends on the actual environmental conditions.Our study aims to reveal specific details of photolytic degradation of pesticides as important soil contaminants. Significance of these studies is enhanced by the fact that pesticide decomposition may contribute to soil degradation, and have harmful biological effects by degrading to toxic products. The toxicity of the examined pesticides is well known, however very little information is available regarding their natural degradation processes, the quality, structure and biological impact of the degradation products.The photolytic degradation of frequently applied pesticides of distinctive types (acetochlor – acetanilide, simazine – triazine, chlorpyrifos – organophosphate, carbendazim – benzimidazole) was investigated. A special, immerseable UV-light source was applied in order to carry out photodegradation. The degradation processes were followed by thin layer chromatography (TLC) and mass spectrometry coupled with gas chromatography (GC/MS). EI mass spectrometry was used to identify the degradation species.Each of the studied pesticides underwent photolytic decomposition, and the detailed mechanism of photolytic transformation was established. At least four degradation species were detected and identified in each case. Loss of alkyl, alkyloxy, amino-alkyl and chloro groups might be regarded as typical decomposition patterns. Deamination occurred at the last stage of decomposition.

Published: September 2019

There are several methods used in the identification process of human remains. The most of them are based on comparing of antemortem and postmortem data available. Although the technique of fingerprinting is considered more accurate in many cases, it cannot be used when the bodies are mutilated, decomposed, burned, or fragmented. This article aims to compare the metric values obtained by Galvão (1994) and Saliba (2001) to differentiate male and female through dry skulls, using the measurement of the Radiocef Studio 2 Program. It was used 16 teleradiographs (11 females and 5 males). The linear measurements used in this article were: 1. The bodies stature of the mandible; and 2. Distance Nasium-Front Nasal Spine. Several radiological techniques are used to aid the human identification process for determining sex, ethnic group, and age. The analyses of X-rays and Computer Tomography (CT) scans, antemortem and postmortem, have been an important tool for human identification in forensic dentistry, especially with the refinement of techniques acquired with the advancement of radiology and CT scans. We concluded that the knowledge of the best method by forensic dentists with a careful application of the technique and report’s interpretation is essential to fulfilling the necessary characteristics for a successful identification of sex using skull measures.

CONCEPTS AND MODELS IN SOCIAL POLICY
Authors: Terziev Venelin , Dimitrova Preslava
Published: September 2019

The social policy of a country is a set of specific activities aimed at regulating the social relations between different in their social status subjects. This approach to clarifying social policy is also called functional and essentially addresses social policy as an activity to regulate the relationship of equality or inequality in society. It provides an opportunity to look for inequalities in the economic positions of individuals in relation to ownership, labor and working conditions, distribution of income and consumption, social security and health, to look for the sources of these inequalities and their social justification or undue application.The modern state takes on social functions that seek to regulate imbalances, to protect weak social positions and prevent the disintegration of the social system. It regulates the processes in society by harmonizing interests and opposing marginalization. Every modern country develops social activities that reflect the specifics of a particular society, correspond to its economic, political and cultural status. They are the result of political decisions aimed at directing and regulating the process of adaptation of the national society to the transformations of the market environment. Social policy is at the heart of the development and governance of each country. Despite the fact that too many factors and problems affect it, it largely determines the physical and mental state of the population as well as the relationships and interrelationships between people. On the other hand, social policy allows for a more global study and solving of vital social problems of civil society. On the basis of the programs and actions of political parties and state bodies, the guidelines for the development of society are outlined. Social policy should be seen as an activity to regulate the relationship of equality or inequality between different individuals and social groups in society. Its importance is determined by the possibility of establishing on the basis of the complex approach: the economic positions of the different social groups and individuals, by determining the differences between them in terms of income, consumption, working conditions, health, etc .; to explain the causes of inequality; to look for concrete and specific measures to overcome the emerging social disparities.
CONTRIBUTION OF EDUCATION TO SOCIAL CAPITAL DEVELOPMENT
Authors: Ilić Vojislav , Novaković Igor , Cvetanović Slobodan
Published: September 2019

During the last decade of the last century, the concept of capital in scientific literature has been significantly expanded. Namely, for decades, the belief that the category of capital includes only visible resources has been modified in terms of extending its comprehensiveness to intangible resources, such as human and social capital. Human capital encompasses knowledge, skills, competencies and characteristics embodied in the individual, which enable the creation of personal, social and economic well-being, while social capital represents the capital of cooperation, interaction, mutual trust and help. When it comes to education, the ability to acquire the necessary knowledge, skills and competences is crucial for the economic and social progress of individual countries. Unlike physical capital that is completely tangible, human and social capital are intangible. Recent approaches, as components of human capital, in addition to education and the level of health status of the population, outline the characteristics of people and societies that have an impact on the effects of work, including factors of ability, motivation and culture, etc. Some experts extend the content of human capital to individual characteristics of people such as creativity, innovation, motivation, attitudes (about life, business, etc.), diligence, responsibility, perseverance, self-initiative, communication success, problem solving, critical thinking, self-study, flexibility and adaptability. The paper considers the contribution of education as one of the basic and absolutely indisputable component of human capital to the development of social capital. It has come to the conclusion that countries with high education of the population tend to become richer and to invest more and more resources in the development of their own processing system. Therefore, in current business conditions in the process of creating human capital, the importance of activities focused on lifelong education and professional development is especially important. Both types of capital are developing in close interdependence. The increase in human capital corresponds significantly to the development of social capital. On the contrary, social capital represents an essential premise of increasing the efficiency of human capital. Moreover, there is not a small number of authors who regard certain attributes of social capital as human capital components. Considering the contribution of education as a component of human capital to the development of social capital, it can be concluded that education does so because it helps young people to recognize their duties as members of society, promote civil and social engagement of people and influence human behavior. Citizens with higher education have a high degree of civic and social engagement. The educated people are much more involved in their communities and take practical steps to improve the welfare of communities in which they live contributing, among other things, to the development of social capital.

In this type of environment a lot of competence is necessary for the leaders to survive. The aim of this study case was to explore i.e. gain a clearer picture of the position of the leader, their characteristics, functions, levels, the core and the factors affecting the leader and their leadership. To see what type of leader the people want simply to draw conclusions about the characteristics, qualities and techniques of a leader and their leadership. So that in the end, to have empirical proof of the leader. The set goal in this study case is today’s leaders in everyday process, starting from the very beginning of their work, to serve as an example in developing inter-personal skills at the same time as treating people with dignity and respect. In other words, they have to possess leadership skills, characteristics and the necessary actions. This research aims at finding out the real attributes that is the profile of a leader and their leadership running an organization regardless if it is economic, political, and military or some other non-governmental organization. The values are more than a set of rules, they are not only behavior code, and they say what a leader should be every day in every action that they take. The values shade the leaders’ identity and the organization that they run.
THE МEANING OF PUBLIC-PRIVATE PARTNERSHIP FOR DEVELOPMENT OF LOCAL SELF-GOVERNMENT
Authors: Risteska Sandra
Published: September 2019

Each country strives for growing economic development, but no country is able to implement it. Various experiences and projects from the countries of the European Union and other neighboring countries are taken and considered. Towards the end of the 20th century and at the beginning of the 21st century, economic movements are increasingly relying on public-private partnerships, which can lead to a rapid development process through the financing of infrastructure projects. Economic globalization, as well as the emergence of new opportunities for economic activity in the world, are aimed at cooperation of the authorities and businesses in the realization of the socio-economic policies. The implementation and realization of development projects through public-private partnerships is impossible without participation by the relevant institutions of the public and private sector. Above all, direct participation implies expertise, experience and education. Every project that will be realized through various forms of public-private partnership must fulfill certain conditions. Among the conditions for proper implementation of the project are: dialogue, transparency and monitoring. The main feature of PPP is the transfer of the risk to the financing, efficiency and quality of public services, which are usually the burden of the private partner. This paper analyzes and explores the essence of public-private partnership. The conceptual framework for public-private partnership, as well as its strengths and weaknesses, is set. With the application of PPP, the economic development of the infrastructure as a whole, and in particular the development of local infrastructure, is analyzed. The origin of PPPs, its characteristics, as well as the need and importance for their continuous implementation are explained. The application of PPP is considered through the experiences in certain countries of the European Union and the Republic of Macedonia. Then, the responses to previously hypothesized hypotheses are collected: what is the successful implementation of PPP, what is needed for PPPs and why. In the end, the data from the conducted research are collected, analyzed and determined the profile of certain activities, as well as the possible decisions for further strategies for the implementation of the PPPs.
SOURCES OF THE POWER AND THE AUTHORITY OF MANAGERS
Authors: Belovski Vojo , Todorova Biljana
Published: September 2019

The paper starts from the general approach to the content and essence of the categories of power and authority and their interrelationship at the level of theoretical analysis and practical existence and manifestation.The sources from which the power and the authority of managers emerge will be analyzed taking into account their position and role in the organizations and other forms of the existence of the managerial function.The power is the right to order and obligation to respect / apply the order - it is very present in the work and behavior of the managers. The power is visible in the area of the state activities, in the education system, among the family.The authority represents carrying out the will even when it is contrary to the interests of others. You can talk about economic, ideological, religious, media authority, the authority of political parties and interest groups.Organizations are composed of persons who perform greater or lesser degrees of authority and power. Sometimes the power and authority in the organization arise from the position of a person in the organization or from the knowledge and skills that a person possesses. Others express their authority in interpersonal relationships through their character. In practice, it is seen that individuals have formal power and no real authority.Most directly, the authority of managers is derived from their functions / activities in the enterprise, from the right to command and direct other people in their tasks and responsibilities. Their power stems from the right and the ability to create an environment in which other individuals will participate in the realization of the organization's goals, in other words, the right to create an atmosphere that will encourage people to dedicate themselves to the work and development of the enterprise.The authority of managers arises from their intellectual knowledge, often higher than the knowledge of employees, which also activates authority as a voluntary acknowledgment of influence on the subordinate.Through an analytical approach, analyzes will be made on some issues and aspects of the status of managers in the Macedonian society, through projected grouping / classification of types of managers. Also, an answer to the question of why the managerial function in the Republic of Macedonia is reviving.

Investigation of electric generator robust algorithm under measurement noises
Authors: Furtat Igor B. , Nekhoroshikh Artem N.
Published: September 2019

The paper considers the investigation of a novel robust control algorithm of an electric generator with unknown parameters under bounded disturbances and high-frequency measurement noises. It is assumed that only the load angle is available for measurement, but not the rotor speed. The electric generator model is described by a system of third-order nonlinear differential equations with algebraic coupling ones. The proposed algorithm consisting of static and dynamical terms is based on the separation of the filtering and estimating properties. Differently from existing results the proposed scheme provides the opportunity to control independently the quality of filtering and stabilization. Investigations show that the proposed algorithm attenuates parametric uncertainties and disturbances with accuracy that can be reduced by tuning algorithm parameters.
Longitudinal motion stability of electrons inside the plasma channel of LPWA
Authors: Polozov Sergey M. , Rashchikov Vladimir I.
Published: September 2019

The acceleration of electrons in laser-plasma channels is one of the contemporary ideas on the energy frontier of accelerators. Demands of low energy spectrum and emittance are especially important for discussed colliders and light sources based on acceleration in plasma channels. The idea to use a laser-plasma accelerator as injector for these installations instead of traditional RF linacs looks like as a very perceptive way to replace the conventional RF linac-injector or linac-driver by a very compact system. Therefore, the new results of beam dynamics simulations in laser-plasma channel having pre-bunching stage are discussed in paper. Main simulations were focused on the study of the longitudinal electron motion stability inside of the plasma channel.
It was shown that the form and the value of the plasma potential well are essentially depend on laser pulse amplitude, form and duration. The electron beam dynamics, in turn, is specified by plasma potential well parameters, which define the electrons capturing into acceleration and output parameters of the bunch. Electrons loosed from the synchronous motions in the plasma wave are defocusing soon after falling out from the potential well and are pushed to the plasma channel wall.

Published: September 2019

This paper provides stability analysis results for a linear mechanical system with a large parameter at the vector of gyroscopic forces and with delay in positional forces. Both cases of discrete and distributed delay are studied. Using the decomposition method and Lyapunov–Krasovskii functionals, conditions are found under which delay does not disturb the asymptotic stability of the considered system. The effectiveness of the obtained results is illustrated by a simulation example.

An experimental platform for statistical fault diagnosis in propelled mechanical systems: an academic exercise
Authors: Acho Leonardo , Caballero Pablo Buenestado
Published: September 2019

Statistical data analysis for fault diagnosis in mechanical systems is a fundamental tool, for instance, in applied mechanical engineering. In order to capture a feasible data set, a well designed electronic instrumentation and excitation system signal stages are mandatory.
Hence, one objective of this paper is to develop a low cost vibration sensor based on an inductive LC-tank oscillator (a resonant inductive-capacitive electronic circuit carefully designed to produce an harmonic electrical signal), and then to tune an effective excitation system signal to our experimental platform. This platform uses a propelled drone motor mounted on a beam structure to emulate a propelled rotating machine. Essentially, two data set were acquired. One for the healthy behaviour of the developed system, and the other for a programmed faulty scenario. This defective case was realized by introducing a small mechanical fault in one blade extreme of the mechanical propelled system. To note, this faulty scenario is almost impossible to deduce by just seen the raw data. The other objective of this paper is to analyze the obtained data sets by utilizing a statistical data analysis tool. Then, by employing box-plot diagrams, the healthy and faulty cases become evidenced. Finally, and due to we are proposing a low-cost academic experimental platform for fault diagnosis based on data analysis, our platform’s toll was around 120 euros. Hence, this platform results applicable to teach data analysis from dynamical systems.

Published: September 2019

This article proposes a design of 400 watt inverter with frequency of 50 Hz at voltage of 12 Vdc input and 220 Vac output. This inverter is designed to convert the Direct Current (DC) into Alternating Current (AC) voltage with the purpose to utilize DC electricity generated by renewable energy. Hence, the energy can be employed as the replacement of the commercial electricity. In this research, the inverter is designed with the use of Switching High Frequency (SHF) method as the amplifier system applied for step up input voltage. Besides, the proposed inverter also utilizes the Sinusoidal Pulse Width Modulation (SPWM) method as the driver resulting the output signal in the form of pure-sine-wave. Furthermore, the switching system for SHF method in this research employs Arduino nano as the control and EGS002 as the SPWM driver. To obtain the real data, the examination is performed with connecting the inverter directly to the load, e.g., bulb, fan, and solder. Finally, the examination and analysis of the implementation result confirm that the design works well and fulfills the expected specification. Hence, this inverter design can be expected to provide the scientific contribution and applied for renewable energy especially in Indonesia, and generally in the world.

El hombre habita un increíble planeta que le ha permitido desarrollarse a partir de inﬁnitos procesos de aprendizaje. La naturaleza le ha puesto innumerables obstáculos, diferentes desafíos que han producido, entre muchas consecuencias, el estado de avance de la tecnología en que nos encontramos. Junto a la maravillosa bendición de poder pensar y aprender día a día, también somos máximos responsables del cuidado de la Tierra y de todos los seres que la habitan en virtud de los procesos ajenos a la naturaleza que impulsamos. Uno de los oponentes de mayor magnitud al que nos enfrentamos es el de poder emplear las energías denominadas alternativas para disminuir el estado de deterioro en el que se encuentra nuestro hábitat consecuencia del mencionado accionar. Esta tesis no pretende de ninguna manera responder a cuestiones filosóficas especiales de índole alguna. No obstante, la conjunción de distintos aspectos le da un marco, tal vez especial al problema que trata. En respuesta a las cuestiones establecidas, el desarrollo del aprovechamiento de estas energías ha ido progresando (lentamente) con el transcurso del tiempo. Si además se suman las necesidades de agua en regiones remotas, la provisión del vital elemento a través de un medio alternativo de energía es una solución viable, punto en el que se centra este trabajo de tesis aplicando herramientas apropiadas, es decir, que garanticen robustez, conﬁabilidad y de bajo costo. El trabajo tiene por objetivo, establecida una problemática real, tratar de resolverla de manera práctica. Se ha tomado en cuenta además, el objetivo de maximizar la extracción de energía del recurso eólico disponible y si éste fuera excesivo, obtener lo máximo contemplando las limitaciones de los componentes del sistema. Respecto de emplear tecnología robusta, se han considerado elementos de probado uso y conﬁabilidad de trabajo y cuando esto no fuera evidente se ha demostrado tal característica. Debido a las características no lineales del sistema, a las perturbaciones y a la variabilidad de la fuente primaria de energía, a las restricciones en la medida de la velocidad del viento, la eﬁciencia, conﬁabilidad y robustez de este tipo de sistemas, están fuertemente ligadas a la efectividad de su control. Luego, en esta tesis se propone y se evalúa la aplicación de conceptos de regímenes deslizantes para optimizar el comportamiento del sistema. Es decir, el diseño del control se sustenta en una teoría con cualidades y características inherentemente robustas, además de una implementación relativamente sencilla y, por ende, de bajo costo. Luego, este trabajo se basa en la aplicación de un control que contenga las características citadas en el marco de una posible implementación práctica.

El presente trabajo sobre la participación de las organizaciones internacionales en el proceso de redemocratización del Perú, entre 1992 y 2000, nace a partir de la necesidad de contribuir a la reflexión sobre el desafío que implica el fortalecimiento de la institución democrática. Se evaluará la eficacia de estas organizaciones, frente a la crisis democrática que afrontó Perú. Entendiendo que se produjo una "interrupción abrupta del proceso institucional democrático o del ilegítimo ejercicio del poder por un gobierno democráticamente electo". Tiene especial importancia desentrañar este nefasto episodio que vivió mi país durante una década, dejando huellas imborrables que generaron resentimientos y brechas profundas.

La cultura organizacional como un determinante de la gestión en tiempos de cambios: períodos 1996-2008
Authors:   , Carrizo Carlos Alberto
Published: September 2019

La tesis que presentamos centra su exploración en la relación que se evidencia en aquellas cuestiones vinculadas de manera indivisible como ser lineal las trayectorias, identidades, relaciones sociales y el proyecto institucional de la gestión de grupos de gestión operativos (administrativos de carrera) y políticos de la Presidencia (generalmente denominado RECTORADO) de la Universidad Nacional de La Plata. Durante el aquí denominado proceso de post “normalización” de las universidades nacionales de La Plata desarrollado entre diciembre de 1995 y diciembre de 2007, consecuencia ello del proceso de Reforma de Estado Nacional. Centraremos nuestra atención en la cultura de control organizacional desde una perspectiva de gestión y experiencias que esos actores sociales desarrollaran en los ámbitos propios de su sociabilidad universitaria y en otros espacios de la vida social y política para legitimar su posición y orientar las decisiones institucionales, con especial referencia a las relativas a la gestión administrativa. A partir de indagar en el ambiente de control interno, reconocer cómo se reconfiguraron los procesos de trabajo de los distintos grupos administrativos, qué significados esos actores produjeron acerca de las políticas de control instrumentadas desde el Sector Público Nacional y qué prácticas desarrollaron para adaptarse al Control Externo e Interno emanados de la órbita pública.

Fundamentos y pautas para una Gestión Ética y Socialmente Responsable (GESR)
Authors:   , Fantasia José Augusto
Published: September 2019

Aunque los temas de ética y de responsabilidad social tienen un cierto carácter intangible, no pueden dejarse a la buena voluntad de las personas; pueden y deben gestionarse. Nace de esta manera el concepto de Gestión Ética y Socialmente Responsable (GESR), actualmente voluntaria, que requiere a la organización un compromiso que demuestre su integración en la estrategia y procesos; el impulso del diálogo y el conocimiento de las expectativas de los grupos de interés (entidades o individuos a los que pueden afectar de manera significativa las actividades, productos y/o servicios de la organización) y el fomento de la transparencia y la comunicación (publicación de la triple cuenta de resultados: económico, social y ambiental). Por cuestiones de naturaleza y de condiciones del mercado, en este trabajo se analizan las percepciones y acciones de cinco empresas del Sector Farmacéutico: Bagó, Bayer, Novartis, Roche y Roemmers, para evidenciar el compromiso que este Sector tiene con la GESR.

Segregación escolar por nivel socioeconómico
Authors:   , Vazquez Emmanuel José
Published: September 2019

Este trabajo hace uso de datos suministrados por el Programa Internacional de Evaluación de Alumnos (PISA) con el objetivo de proveer una cuantificación de los niveles y la evolución de la segregación escolar por nivel socioeconómico en el mundo y contribuir a la discusión de sus determinantes. Los resultados sugieren un ranking de países que muestra a América Latina como una región de alta segregación escolar en términos relativos y donde la segregación entre escuelas públicas y privadas es relevante. Se encuentra además que la segregación escolar por nivel socioeconómico es mayor en aquellos países y períodos de tiempo en los que la desigualdad y la participación del sector privado en la matrícula es mayor, en tanto ciertos patrones de localización geográfica pueden también jugar un rol importante.

Desarrollo y validación intra-laboratorio de una metodología para la detección de Salmonella spp. en carne bovina molida
Authors:   , Aliverti Virginia
Published: September 2019

La salmonelosis es una de las enfermedades transmitidas por alimentos más frecuente en el mundo. El Código Alimentario Argentino establece para carne molida la ausencia de Salmonella spp. y para su análisis recomienda la norma BAM. Esta metodología requiere tiempo hasta obtener el resultado final. La PCR se utiliza como método rápido para la detección de patógenos. El objetivo de este trabajo fue prevenir la presencia de Salmonella spp. en la carne molida destinada a consumo minorista. Se desarrolló una técnica de PCR en tiempo real (RT- PCR) con agentes intercalantes para la detección de Salmonella spp. y se realizó una validación intra-laboratorio. El límite de detección fue 104 UFC/20 μl de mezcla de reacción. En esta etapa la técnica presentó 100% de inclusividad y exclusividad. Se comparó el desempeño de esta técnica contra una PCR de punto final y una RT-PCR comercial mediante el análisis de 92 muestras de carne molida obtenidas de carnicerías de la ciudad de Berisso. Durante el muestreo se realizó una encuesta al responsable del comercio. Se obtuvieron 13 (14%) muestras positivas por aislamiento y por RT-PCR comercial y ocho (8,7%) muestras positivas al utilizar PCR de punto final y la técnica desarrollada. Se aislaron 5 serotipos de Salmonella. El desempeño de la RT-PCR desarrollada se puede mejorar mediante el rediseño de los oligonucleótidos cebadores en base a los clones circulantes aislados en la carne molida. En las encuestas se identificaron problemas como: falta de trazabilidad de la carne, falta de procedimientos de sanitización estandarizado y carencias edilicias. El Programa “Carnicerías Saludables” permitió detectar los puntos críticos en las etapas de triturado y envasado de la carne molida y de esta forma implementar estrategias de prevención y control de salmonelosis por medio de la capacitación de 167 manipuladores.
