Reconstrucción del Pabellón Auricular con Cartílago Costal Autólogo en Microtias - Técnica del Prof. Juarez Moraes Avelar, Primer Tiempo Quirúrgico
Authors: Suárez Oyhamburú Darío Lautaro
Published: December 2021

La reconstrucción del pabellón auricular es aún una cirugía poco frecuente en nuestro medio. La OMS reporta que 1 de cada 8000 nacidos vivos, presenta algún grado de malformación congénita auricular. En el presente trabajo utilizo la clasificación de Microtias de Avelar con sus características particulares que así las determina en severas o moderadas y empleo el modelo del tallado del cartílago autólogo también descrito por mi profesor. Dos son los tiempos operatorios principales aunque dejo un tercero para realizar afinamientos estéticos que sean necesarios. La edad apropiada para operar oscila entre los 6 a 8 años de edad donde la oreja sana ha alcanzado el 80 % del tamaño total y las costillas alcanzan un volumen considerable para ser talladas. Retiro el cartílago de la 8va. y/o 9na. costilla siempre del lado derecho y no así del lado izquierdo, tanto para las microtias del mismo lado como para las microtias del lado izquierdo, en este caso simplemente se evierte el segmento cartilaginoso a tallar guiándome con un molde de un pedacito de una radiografía tomado de la oreja sana contra lateral. No tengo experiencia empleando prótesis auriculares de silicona, porex, medpor o poliuretano. Dos son los pasos que sigo a la hora de operar cuando determino el tipo de Microtia presentada: 1ero. Modelar el esqueleto cartilaginoso y 2do. Lograr una cobertura cutánea del área temporo mastoidea que es muy poco distensible.

En vista que la cirugía de aumento mamario viene en ascenso en las ultimas décadas, es un reto para el cirujano plástico obtener buenos resultados con mínimas incisiones. Una de las preguntas de nuestras pacientes en el momento de realizar la consulta sobre aumentar el tamaño del busto y corregir la ptosis es sobre la cicatriz resultante. Temen abordajes grandes y heridas visibles que entorpezcan la apariencia estética de la mama. El desafío es colocar el implante y subir la mama al mismo tiempo.

Dependiendo el grado de ptosis se utilizan diferentes técnicas quirúrgicas, desde cicatrices periareolar, verticales y en T invertida.

Planteamos en nuestra presentación previa (1), un nuevo procedimiento quirúrgico de mastopexia con abordaje periareolar superior y colocación de implante para el manejo de ptosis mamaria leve a moderada.

Published: December 2021

La hipertrofia de los labios menores o ninfas es una característica física bien descripta en muchos trabajos quirúrgicos previamente publicados. En muchos casos puede provocar sintomatología clínica o social que motivan la consulta de las pacientes.

Aunque no existe un estándar anatómico establecido con respecto al tamaño de los labios menores para ser considerados “normales” la mayoría de los autores considera que dicha normalidad se basa en el concepto de que los labios mayores deben estar al mismo nivel o por debajo del borde de los labios mayores, y que deben converger superiormente y cubrir parcialmente el clítoris cuando se examina a la paciente en una posición anatómica, es decir, con las piernas levantadas.

Las características anatómicas y el aspecto externo de estas estructuras en muchas pacientes interfieren con la higiene personal las relaciones sexuales e incomodan durante el uso de ropas ajustadas por lo que cada vez mas mujeres llegan a nuestra consulta tratando de encontrar una solución a lo que consideran un problema.

La mayoría de las pacientes manifiestan que el aspecto de sus genitales afecta su autopercepción femenina y ese grado de afectación dependerá en mucho de la comparación entre pares o a través de las revistas o material visual de contenido sexual explícito.

Published: December 2021

The main purpose of Industry 4.0 applications is to provide maximum uptime throughout the production chain, to reduce production costs and to increase productivity. Thanks to Big Data, Internet of Things (IoT) and Machine Learning (ML), which are among the Industry 4.0 technologies, Predictive Maintenance (PdM) studies have gained speed. Implementing Predictive Maintenance in the industry reduces the number of breakdowns with long maintenance and repair times, and minimizes production losses and costs. With the use of machine learning, equipment malfunctions and equipment maintenance needs can be predicted for unknown reasons. A large amount of data is needed to train the machine learning algorithm, as well as adequate analytical method selection suitable for the problem. The important thing is to get the valuable signal by cleaning the data from noise with data processing. In order to create prediction models with machine learning, it is necessary to collect accurate information and to use many data from different systems. The existence of large amounts of data related to predictive maintenance and the need to monitor this data in real time, delays in data collection, network and server problems are major difficulties in this process. Another important issue concerns the use of artificial intelligence. For example, obtaining training data, dealing with variable environmental conditions, choosing the ML algorithm better suited to a specific scenario, necessity of information sensitive to operational conditions and production environment are of great importance for analysis. In this study, predictive maintenance studies for the transfer press machine used in the automotive industry, which can predict the maintenance need time and give warning messages to the relevant people when abnormal situations approach, are examined. First of all, various sensors have been placed in the machine for the detection of past malfunctions and it has been determined which data will be collected from these sensors. Then, machine learning algorithms used to detect anomalies with the collected data and model past failures were created and an application was made in a factory that produces automotive parts.

Published: December 2021

Since the invention of cameras, video shooting has become a passion for human. However, the quality of videos recorded with devices such as handheld cameras, head cameras, and vehicle cameras may be low due to shaking, jittering and unwanted periodic movements. Although the issue of video stabilization has been studied for decades, there is no consensus on how to measure the performance of a video stabilization method. In many studies in the literature, different metrics have been used for comparison of different methods. In this study, deep convolutional neural networks are used as a decision maker for video stabilization. VGG networks with different number of layers are used to determine the stability status of the videos. It was observed that VGG networks showed a classification performance up to 96.537% using only two consecutive scenes. These results show that deep learning networks can be utilized as a metric for video stabilization.

Published: December 2021

Cardiovascular diseases, which involve heart and blood vessel dysfunctions, cause a higher number of deaths than any other disease in the world. Throughout history, many approaches have been developed to analyze cardiovascular health by diagnosing such conditions. One of the methodologies is recording and analyzing heart sounds to distinguish normal and abnormal functioning of the heart, which is called Phonocardiography. With the emergence of machine learning applications in healthcare, this process can be automated via the extraction of various features from phonocardiography signals and performing classification with several machine learning algorithms. Many studies have been conducted to extract time and frequency domain features from the phonocardiography signals by segmenting them first into individual heart cycles, and then by classifying them using different machine learning and deep learning approaches. In this study, various time and frequency domain features have been extracted using the complete signal rather than just segments of it. Random Forest algorithm was found to be the most successful algorithm in terms of accuracy as well as recall and precision.

STATIC CONTROL OF DRAG-REDUCING AIR CAVITIES WITH VARIABLE CAVITATOR SHAPE
Authors: Matveev K I
Published: December 2021

Air ventilation of submerged surfaces of ship hulls is a promising technique for drag reduction. To ensure high performance of air cavities in a broad range of operational conditions, the cavity properties can be controlled with help of compact hydrodynamic actuators. In this study, a potential flow theory is applied to model an air cavity formed behind a wedge-shaped cavitator under a horizontal wall imitating a ship bottom. By varying the wedge angle, it is possible to achieve states with maximum drag reduction at given operational conditions. The dependence of the optimal wedge angle on Froude number and hull trim is investigated. The air-cavity ability to reduce frictional drag is found to increase with rising flow speed and bow-down hull trim.

Authors: Kocak G
Published: December 2021

Simulators can be used as sophisticated, flexible and realistic training tools which are capable of meeting many of the designated functions and tasks. An engine room simulator consists of simulation of various machinery systems in the engine room of a ship. This type of simulator is very significant and compulsory for marine engineering education. Istanbul Technical University Maritime Faculty (ITUMF) obtained a set of full-mission simulator and workstation simulators in 2001. However, it was realized that the ergonomic principles were not applied properly. Therefore it was not possible to generate the real engine room conditions with this simulator due to lack of some operations and displays on the mimic panel. Some of the mimics and displays were not similar to ones on board ship. This situation was negatively affecting the performance of engine room simulator training. And the mimic panel was re-designed and installed in 2006. In this study, the ergonomics principles for designing a mimic panel are determined and the application of ergonomic principles to a mimic panel is explained. The ergonomic gains of applied ergonomics principles are mentioned. Even more the effects on the marine engineering education are stated.
DERIVING SAFETY REQUIREMENT HIERARCHIES FOR FAMILIES OF MARITIME SYSTEMS
Authors: Rokseth B , Utne I B
Published: December 2021

Ensuring the safety of advanced maritime vessels is a challenging task. While technological developments provide new options for their design and operation, the criteria for certification, such as class rules intended to ensure safety, may not be flexible enough to accommodate rapid changes. Innovation may enable more efficient, greener, and smarter systems but it may also introduce new hazards that are not addressed by current safety requirements. This paper proposes a method aimed at developing requirement hierarchies that are generic for a family of systems (such as a class of ships) and that can be adapted and specialised for a subset of the family or a particular system. Systems-theoretic process analysis (STPA) is used to develop safety requirements that are structured in a way that ensures that they can easily be kept up to date to accommodate new technological solutions and new alternatives for the design and operation of maritime vessels.

Published: December 2021

The engine fuel piping in LNG-fuelled ships’ engine room presents potential gas explosion risks due to possible gas fuel leakage and dispersion. A 3D CFD model with chemical reaction was described, validated and then used to simulate the possible gas dispersion and the consequent explosions in an engine room with regulations commanded ventilations. The results show that, with the given minor leaking of a fuel pipe, no more than 1kg of methane would accumulate in the engine room. The flammable gas clouds only exit in limited region and could lead to explosions with an overpressure about 12 mbar, presenting no injury risk to personnel. With the given major leaking, large region in the engine room would be filled with flammable gas cloud within tens of seconds. The gas cloud might lead to an explosion pressure of about 1 bar or higher, which might result in serious casualties in the engine room.

The maritime institutions aim at contributing to reducing the adverse effects arising from the ships, machinery operation through the possibilities exit in the engine room simulators. The current paper explains the importance of engine room simulators in maritime education in general and focuses on their use in the field of evaluation and management of machinery within the engine room space. As a case study, an electric powered passenger ship and an oil tanker ship are investigated regarding applying ship energy management onboard. This investigation could be achieved using the possibilities available in TRANSIS ERS 5000. With reference to passenger ships, the results show the possibility of saving energy with a reduction of CO, SOx, CO2 and C emissions by about 7.97, 10.54, 12.36, and 20.11%, respectively. However, regarding tanker ships, the results reveal that a reduction of speed by 10% will achieve fuel saving by about 25%.

Container ships are the type of ships that produce the most emissions in maritime transport. In container transportation not only in navigation but also at container ports, a lot of emissions are formed. Ports are generally close by and highly interacted with the inner parts of the city, the impacts of the gas emissions are quite high on people. The study investigated port selection criteria, in terms of cost, efficiency and especially in terms of environmental impacts in order to create awareness. Container port selection problem was solved using fuzzy TOPSIS (The Technique for Order Preference by Similarity to Ideal Situation) method considering the perspective of carriers. In the study, the container port selection was carried out among the four largest container ports in Turkey.

Published: December 2021

The objective of this work is to analyse the operational behaviour of an offshore multipurpose support vessel designed to operate in the Eastern Mediterranean Sea. First, the seakeeping analysis is performed in a regular wave condition for different heading angles estimating heave and pitch motions through the strip theory. After that, the effects of the vertical acceleration on the bow, occurrence of slamming or hydrodynamic impact of the hull on the surface of the water; wetted deck, occurrence or invasion of water on the deck of the vessel and propeller emersion, motion sickness and wave-induced additional resistance are analysed. The present analysis is extended in an irregular sea condition, and the estimated seakeeping criteria are compared to the acceptable levels. In defining the most suitable operational mode of the offshore support vessels, multi-criteria decision techniques and probabilistic approach are employed to perform an adequate evaluation of the seakeeping performance accounting for different hazardous events through the service life.

Published: December 2021

In the recent years, seawater scrubbers have become an interesting option to reduce SO2 emissions in marine engines. In this regard, this paper proposes a numerical model to analyze SO2 absorption in seawater. A single seawater droplet was analyzed, and the developed model was used to predict the influence of several parameters on the desulphurization efficiency, such as the droplet diameter, SO2 concentration, alkalinity and temperature. It was found that a droplet of 200 μm initial diameter can absorb up to 1.77∙10-14 mol of S for the parameters analyzed, and this reduction improves when the alkalinity and SO2 concentration are increased and diameter, seawater temperature and gas temperature are reduced. Differences up to of 21.5%, 19.8%, 2.2% and 16.3% in the S reduction were obtaining varying the SO2 initial concentration, alkaline initial concentration, initial liquid temperature and initial gas temperature respectively.

Published: December 2021

The bridge crossing water way is in the risk of impact by vessel, and thus it is very important to estimate the collision force for the safety of bridge. The impact force between bridge pier and vessel is investigated by numerical simulation and various empirical formulae. The collision response between a 5000t DWT bulk carrier with bulb bow and rigid bridge pier is simulated in the explicit finite element code of ANSYS LS-DYNA. The difference of the impact force between the empirical formulae and FE analysis are discussed. Based on the comparison of the results, the coefficient in the formulae is suggested for obtaining more accurate assessment of impact force.

Published: December 2021

Specification of the frictional resistance values of tankers is the first step in managing their fuel consumption. Drag force of a very large crude oil carrier has been calculated using the numerical simulation method. With application of the ANSYS CFX software, the scaled model of the mentioned tanker with the length of 2.74 meters, width of 0.5 meters, draft of 0.17 meters was used for numerical simulation of the drag force in the tanker. Furthermore, the numerical solution of the drag force of the model was performed for 5 different speeds ranging from 0.65 to 0.85m/s. Based on the validations carried out, with mean drafts of 8 and 16.5cm, the difference between the results of the experimental and numerical models at low speeds was about 7%. However, the difference was observed to be up to 15% at higher Froude numbers. The results of the present study with respect to the SALINA are based on the method presented in ISO 19030 standard addressing the performance monitoring during vessel servicing.
EVALUATION OF SURVIVABILITY OF A SHIP AFTER DAMAGE WITH APPLICATION OF A RISK CALCULATION METHOD
Authors: Szulczewski P S
Published: December 2021

This paper contains calculations of risk for a selected damage case scenario. The calculations took place with use of a risk model designed for evaluating the safety of ships and were compared with the available and published industry standard (as included in SOLAS 2009) as well. The comparison of results is presented in the form of a discussion and concludes that exact risk levels can be obtained at any stage of the vessel's life. The currently valid method as included in SOLAS 2009 regulation provides limited information about the actual survivability of a vessel in emergency conditions. It is hence very difficult to compare the current probabilistic model with risk based survivability calculations to evaluate the actual safety provided by an investigated vessel should it subsequently be severely damaged.

Determination of hydrodynamic coefficients is a vital part of predicting the dynamic behavior of an Autonomous Underwater Vehicle (AUV). The aim of the present study was to determine the drag and lift related hydrodynamic coefficients of a research AUV, using Computational and Experimental Fluid Dynamics methods. Experimental tests were carried out at AUV speed of 1.5 m s-1 for two general cases: I. AUV without control surfaces (Hull) at various angles of attack in order to calculate Hull related hydrodynamic coefficients and II. AUV with control surfaces at zero angle of attack but in different stern angles to calculate hydrodynamic coefficients related to control surfaces. All the experiments carried out in a towing tank were also simulated by a commercial computational fluid dynamics (CFD) code. The hydrodynamic coefficients obtained from the numerical simulations were in close agreement with those obtained from the experiments.

Published: December 2021

The demand to increase port throughput has driven container ships to travel relatively fast in shallow water whilst avoiding grounding and hence, there is need for more accurate high-speed squat predictions. A study has been undertaken to determine the most suitable method to predict container ship squat when travelling at relatively high speeds (Frh ≥ 0.5) in finite water depth (1.1 ≤ h/T ≤ 1.3). The accuracy of two novel self-propelled URANS CFD squat model are compared with that of readily available empirical squat prediction formulae. Comparison of the CFD and empirical predictions with benchmark data demonstrates that for very low water depth (h/T < 1.14) and when Frh < 0.46; Barass II (1979), ICORELS (1980), and Millward’s (1992) formulae have the best correlation with benchmark data for all cases investigated. However, at relatively high speeds (Frh ≥ 0.5) which is achievable in deeper waters (h/T ≥ 1.14), most of the empirical formulae severely underestimated squat (7-49%) whereas the quasi-static CFD model presented has the best correlation. The changes in wave patterns and effective wake fraction with respect to h/T are also presented.
