Introducción: la apendicitis aguda representa la causa más común de abdomen agudo. El éxito en el manejo de la apendicitis aguda depende de su diagnóstico oportuno. Por este motivo el objetivo del estudio fue evaluar la utilidad de la escala de Alvarado como método diagnóstico para apendicitis aguda en el servicio de emergencia de un hospital general. Materiales y métodos: se realizó un estudio transversal desde julio 2011 hasta abril 2012 en el servicio de Emergencia del Hospital Luis Vernaza. Se incluyeron pacientes >15 años y <76 años que presentaron síntomas sugestivos de apendicitis aguda. Se obtuvo el puntaje de la escala de Alvarado y se recabaron los resultados de la histopatología posterior a la apendicetomía. Se calculó la sensibilidad, especificidad, valor predictivo positivo y valor predictivo negativo. Resultados: se obtuvo que 143 (53.4%) pacientes fueron hombres y 125 (46.6%) fueron mujeres con edad promedio de presentación de 35 años ±16.42 DS. La escala de Alvarado fue aplicada a todos los pacientes y se obtuvo ? 7 puntos en 231 (86.2%) pacientes y ? 6 puntos en 37 (13.8%) pacientes. Se confirmó el diagnóstico de apendicitis aguda en 234 (87.3%) pacientes y se reportaron 34 (12.7%) casos de apendicetomías negativas. Se calculó para esta escala una sensibilidad de 96.6%, especificidad de 85.3%, valor predictivo positivo de 97.8% y valor predictivo negativo de 78.4%. Discusión: la escala de Alvarado resulta útil para el diagnóstico de apendicitis aguda y consecuentemente reduciría la tasa de apendicetomías erradas; presenta alta sensibilidad, alto valor predictivo positivo y negativo y es aplicable en todos los pacientes con sintomatología sugestiva de apendicitis por ser un método sencillo, rápido y económico.

Background
The aim of the study was to compare three widely used algorithms for stratification of the global cardiovascular risk (GCVR): the Framingham Heart Study (FHS) score, the European systemic coronary risk estimation (SCORE) and the Italian ‘Progetto Cuore’ (heart project) score. It was also investigated how preclinical carotid atherosclerosis (pre-ATS) might influence the incidence and improve the risk prediction of cerebrovascular and cardiovascular events.

Methods
Subjects (n = 358) without previous history of cardiovascular disease (CVD) were recruited and the GCVR was calculated for each patient. An ultrasound evaluation of the carotid arteries was also performed.

Results
According to SCORE, the recruited population had globally a low risk of cardiovascular mortality and the risk equation estimated a GCVR of 2% in spite of the in spite of the observed rate of 0.8% (95% CI −0.001 to 0.02) of fatal events. The FHS and the ‘Progetto Cuore’ risk equations, regarding a 10-year risk of fatal and nonfatal events, predicted a low GCVR of 31 and 30%, an intermediate risk of 64 and 66%, and a high risk of 5 and 4% of the population respectively. They also estimated a general GCVR of 6.9 and 6.4% respectively versus an observed event rate 27.7 (95% CI 23.0 to 32.0). The discriminative power, calculated with the area under the receiving operator curve (AUROC), was 0.53 for SCORE, 0.54 for FHS and 0.55 for Progetto Cuore. Based on the ultrasound evaluation of carotid arteries, a first clinical event at 10-year follow-up was reported in 3% of subjects with normal ultrasound examination, 32% with intima-media thickening (IMT) and 62% with asymptomatic carotid plaque (ACP).

Conclusion
The present study has evaluated for the first time the prediction of GCVR in an asymptomatic population, comparing three different risk scores. Carotid pre-ATS was related to the major cardiovascular risk factors (RFs) and was independently associated with a major incidence of cerebro- and cardiovascular events, therefore enhancing the predictive value of the three different risk scores.
Specific Elements of Marketing in the Recruitment and Selection of Human Resources Process in Romanian Army
Authors: Alexandrescu Mihai-Bogdan 
Published: February 2019

Abstract
The issue of recruiting a quality human resource appears to be, more or less, a universal one, and it is not just an issue for the United States of America but also for Europe, as the modern armies are confronting with difficulties in recruiting and retaining military personnel. The reasons are generated by the changes of the values in civil society, as well as by the fact that the interest and motivation of joining the army are declining, especially among young people. The competition between the private labor market and the military organization is increasing due to the high level of education of the younger generation and the unemployment rate. Increasing the confidence of the population towards the army and emphasizing the its role of employer determine the connection with the young people, especially for stimulating the desire and attracting them to the military profession.
Analysis of the Types of Maintenance Systems of Technical Equipment and the Assessment of the Characteristics of These Systems for Selecting the Optimal Variant
Authors: Virca Ioan 
Published: February 2019

Abstract
The use and maintenance of technical systems throughout their lifecycle aims at achieving goals that allow for high values of productivity and availability characteristics of these systems. In the economic policy of each state or private organization or state institution, there is the right to determine the type of adequate maintenance system within the maintenance strategy adopted. Thus, the types of maintenance systems recognized in the technical domain are analyzed from the point of view of the two previously-mentioned features, productivity and availability, thus making the predictive maintenance system, derived from the preventively-planned one, advantageous for all organizations. It is obvious that the current trend is to spread this predictive maintenance system, according to which the interventions will be carried out before the malfunction occurs, depending on the periodically measured values of global pressure, flow, energy consumption, temperature, current, voltage, vibrations, etc.

An underwater spoiler on a warship: why, when and how?
Authors: Bouckaert Bruno 
Published: February 2019

Abstract
There are a lot of energy saving devices for ships on the market, but few have seen wide adoption on naval ships, with one exception: the bulbous bow. The bulbous bow was developed for naval ships in the early 20th century and is now widespread on a variety of ship designs. Many have wondered if the effect of the bulbous bow — reducing the resistance of a ship by reducing the bow wave — could be replicated somehow at the stern — by reducing the stern wave. This is exactly what is done by a novel and patented energy saving device called Hull Vane®.
Invented by Dutch hydrodynamicist Dr Peter van Oossanen for an America’s Cup sailing yacht in the early 21st century, research over the years has shown that this wing-shaped appendage works best on ships that combine a relatively high displacement with a relatively high top speed requirement — even if most sailing hours are done at half speed. Examples are certain offshore vessels, superyachts, patrol vessels and naval ships. On offshore patrol vessels, the resistance reduction from the Hull Vane® ranges typically from 10 to 20% over the entire useful speed range.
In this paper, the working principles of the Hull Vane® will be described to give a better under-standing of the device. An overview will be given of the work carried out on naval ships and coastguard ships (25 to 142 m), based on Computational Fluid Dynamics studies, model tests and full-scale applications. The question ‘Why?’ will be answered by translating the hydrodynamic effects to concrete capability improvements for naval ships: a lower fuel consumption, a longer range, reduced signature, a higher top speed and improved seakeeping.
The question ‘When?’ will zoom in on whether a Hull Vane® is something to be included in a newbuild or if it is something to be retrofitted to an existing ship. Finally the answer to the question ‘How?’ will explain the process of either integrating a Hull Vane® in a newbuild project or retrofitting it during a midlife upgrade of an existing ship.

Heavy metal pollution is one of serious problem for tropical mangrove ecosystem. Heavy metals can decrease the quality of a waters. The decreasing in water quality can caused by pollutants such as heavy metals with high concentrations greatly affects the aquatic environment, especially living organisms. The aimed of study is to determine the accumulation level of heavy metals such as Al, Cu, Pb, As, Ni, Cr, Ti, Mn, dan Fe, in root, leaves and stem of E. acoroides. The sampling was carried out in the northern and southern parts of Tunda Island, in March 2015. The method used for seagrass destruction is 6 mL 65% HNO3 and mL H2O2 30%, sediment destruction using Milestone Start D microwave labstation. and using ICP-OES (Inductive Coupled Plasma-Optical Emission Spectrometry) Thermo Scientific iCAP 700 Series. The result show that, the Al, was the dominant heavy metals observed both in sea water and sediment surrounding the observed sea grass areas. Similar result was also observed for seagrass. The dominant sediment grain size absorbing heavy metals is silt-clay because it has more organic matter to control the binding of heavy metals. Heavy metal bioaccumulation is predominant in seagrass leaves and stems due to heavy metal entry into seagrass, substance storage tissue, and seagrass characteristics that are completely submerged in water. Seagrass meadow ecosystem in Tunda Island has been contaminated by several heavy metals.
Ситуация на рынке продовольствия: новые сигналы и старые проблемы
Authors: Белова Т. Н. 
Published: February 2019

Современная ситуация на агропродовольственном рынке характеризуется, с одной стороны, дифференциацией его сегментов по степени насыщения, а с другой–снижением спроса. Падение реальных доходов населения обусловило снижение потребительского спроса и увеличение доли расходов на питание в домашних хозяйствах, о чем свидетельствует анализ региональной статистики. В последние годы растет расслоение как по производству, так и по потреблению продовольствия на душу населения. Опережающий рост цен на продовольствие ставит под сомнение верность выбора мер и инструментов политики протекционизма. Правильный протекционизм, по мнению автора, не может осуществляться за счет снижения уровня жизни населения, а должен сочетать рыночные механизмы с точечной временной поддержкой тех отраслей экономики, для которых характерны растущая доходность и высокая отдача на инвестиции. Автор считает необходимым использование инструментов «зеленой корзины» (в частности программу продовольственных карточек), отмену эмбарго на импорт продовольствия и дифференциацию экспортных и импортных таможенных пошлин в зависимости от степени насыщения и сформированности внутренних отраслевых рынков.
