Authors: Urrutia Aguilar María Esther , Ortiz León Silvia , Jaimes Medrano Aurora Leonila
Published: January 2021

Los estudios sobre brotes epidémicos generalmente reportan consecuencias negativas asociadas con el confinamiento y su impacto en la Salud Mental; en la educación es importante estudiar los efectos sobre todo en los docentes ya que, es un profesional que durante la pandemia tuvo que migrar de una modalidad presencial a una modalidad remota para impartir sus clases, generando en muchos estrés debido a que no contaban con la preparación suficiente para realizar esta tarea; además, en los docentes recae la responsabilidad deconducir los procesos de enseñanza y aprendizaje , por lo que deberán de fortalecer su resiliencia que puede ayudar a mitigar las repercusiones en los procesos cognitivos de los estudiantes. Por lo que este estudio tuvo como objetivo, identificar las emociones y reflexiones que experimentaron los profesores de bachillerato que se encontraban cursando, durante el confinamiento, la Maestría en Docencia para la Educación Media Superior, con el propósito de reconocer los componentes emocionales que participan en la construcción de la resiliencia frente a la adversidad. Se realizó un estudio exploratorio de corte transversal y analítico; a los participantes se les solicitó elegir un video y de ahí se establecieron las preguntas para la expresión de los sentimientos. El análisis de los resultados se llevó acabo por medio del programa worditout (software gratis) que transforma el texto en nubes de palabras,se realizó un análisis bivariado utilizando el paquete estadístico SPSS versión 20. Las preguntas con respuesta abierta fueron analizadas desde la construcción de la narrativa. Los resultados arrojaron que los profesores mostraron en su mayoría emociones positivas ante la crisis generada por el COVID-19, que pudieron estar asociadas a la construcción de la resiliencia y que les ayuda a tener una perspectiva constructiva a pesar de la contingencia o adversidades.

Published: January 2021

Analizamos previamente los requisitos psicológicos para la correcta adquisición de las competencias lingúisticas, tan importantes en una sociedad alfabetizada, centrándonos en el entrenamiento de la conciencia fonológica como buen predictor de la capacidad lectora. Se ha elegido el Programa LOLE (Mayor y Zubiauz, 2011) por su concepción del préstamos de ayudas al alumno/a, en la línea de la teoría vygoskyana. A partir de él se elabora un programa para entrenar en conciencia fonológica trabajando desde la perspectiva de la evaluación dinámica. Se usan las ayudas que presta el programa para adaptarnos a la ZDP de cada alumno. También se pretende dar a conocer a los maestros el programa. Se aplicó en una muestra de 25 alumnos de 5 y 6 años de edad de tercero de Educación Infantil de un colegio concertado de Valladolid. Se efectuó un registro detallado de las ayudas generales y específicas (en rima, sílaba y fonema) que precisó cada alumno y de su evolución. En la metodología se han utilizado técnicas para mejorar la atención, motivación y autoestima. La aplicación ha permitido detectar alumnos con necesidades específicas, así como mejorar y valorar sus progresos fonológicos (únicamente el 28% de los alumnos han logrado resolver las actividades de forma autónoma). Del análisis cuantitativo y cualitativo se concluye que un número importante de alumnos no ha asimilado aun convenientemente las actividades más elementales de concienciación fonológica y es necesario reforzar y optimizar el aprendizaje de éstas mediante un entrenamiento sistemático
Three Links in a Golden Chain
Authors:   Monash University, Clayton, Victoria, Australia, Bigelow John
Published: January 2021

One of Plato’s dialogues, the Timaeus (ca 370 BCE), describes an abstract numerical pattern that is said to have guided the creative work of an artisan, the Demiurge, who designed both the soul that animates the material world as a whole and the souls of each of the sentient beings that live within this world. Any artist or artisan who took this creation story seriously might reasonably be motivated to take guidance from this same numerical design in his or her own creative work, hoping thereby to mirror the macrocosm in the microcosm of a work of art. Have any artists in history tried to do that? Three likely candidates will be examined here. The first is Plato himself (in a short narrative of the generation of the pantheon of Greek gods, which he recounts in the Timaeus). The second is an unknown Medieval author of an epic poem about Charlemagne (The Song of Roland, ca. 1100 CE). The third is Iris Murdoch (in a novel, The Unicorn, 1963).
The Challenges of Attaining the Millennium Development Goals (MDGs)

Published: January 2021

The history of the millennium development goals (MDGs), the achievement of which experienced a major setback with the outbreak of the 2008 global economic and financial crisis, may provide some useful insights on the global partnership for the sustainable development goals (SDGs). There is a vast literature devoted to the MDGs. Most of the analysis is focused on the implementation and progress made toward achieving the MDGs. Fewer authors explore reasons for shortfalls or describe intrinsic limitations to the MDG framework, including limitations in the development, formulation and content of the MDGs themselves. This article reviews cooperation on the MDGs, exploring the priorities of different stakeholders and the challenges to progress inthe broader context of development and global governance.The review focuses on MDG 8, developing a global partnership for development. Added to the MDGs due to Kofi Annan’s leadership, MDG 8 helped to attract support from developing countries which viewed the MDGs as reflecting a one-sided deal favouring the interests of rich countries. Inclusion of the goal to reform the international economic system appeased some critics of the international development goals that were put forward by the Organisation for Economic Co-operation and Development (OECD) and taken as the basis for the MDGs. This article argues that despite the endeavour by the United Nations (UN) General Assembly to steer the development of global partnerships, extrinsic barriers such as lack of political will on the part of the key stakeholders, the financial crisis, and vested interests prevented deliveryon MDG 8’s key target ofdeveloping an open, predictable, rule-based, non-discriminatory trading and economic system. Achievement of this goal is necessary in order to create the equitable and inclusive international order demanded by developing countries for decades. Most markedly, a lack of progress on MDG 8’s goal of addressing systemic issues of global economic governance became the greatest challenge to achieving the MDGs, and the greatest disappointment. Systemic problems were inherited by the SDGs, the achievement of which requires a truly global partnership able to build a new economic order as a foundation for inclusive and sustainable development. This review draws on content analysis of General Assembly resolutions and the official records of its 55th to 70th sessions, documents from the three conferences on financing for development, the crisis summit, reports on MDG results, and public statements and analytical narratives about the MDGs
RNA-Stable Isotope Probing v5
Authors: Angel Roey , Petrova Eva , Lara Ana
Published: January 2021

The following protocol describes how to perform an RNA-Stable Isotope Probing experiment. The scope of this protocol only covers the parts involving separating labelled RNA from unlabelled RNA using ultracentrifugation in a caesium trifluoroacetate density gradient and downstream quantification to evaluate whether the labelling and separation of the RNA were successful. Total RNA should be extracted from an environmental sample or an enrichment culture that was incubated with an isotopically-labelled substrate. Labelling can be of the carbon, oxygen or nitrogen in the RNA (or any combination of the 3). For environmental samples, we recommend extracting RNA using our protocol Total Nucleic Acids Extraction from Soil and purifying it using the Purification of RNA from Crude NA Extract protocol. This protocol is based on the following papers: Whiteley et al. (2007); Dumont et al. (2011); Angel and Conrad (2013). For a comprehensive discussion on how to design a SIP experiment and how to analyse the resulting data, we recommend referring to the recent book on the subject: Stable Isotope Probing: Methods and Protocols, especially chapters: 1-3 and 9-18.

In this paper, a number of issues related to the use of word embeddings for solving the problem of classifying text documents were considered. Models of word embeddings have been a popular object of theoretical research since the mid-1970. The development of these models, including the transition from count based models to predictive ones, was stimulated by the need to reduce the large computational costs arising from their practical use. This problem is still relevant today. When solving practical problems, one often has to abandon the independent construction of word embeddings and use ready-made solutions. As a result, the problem of post-processing of the existing word embeddings, for example, reducing its dimension, becomes urgent. Recently, a number of works have appeared in which an unusual approach to using the principal component analysis to reduce the dimension of word embeddings has been investigated. In this approach, projections are removed not on the last, but on the first principal components. It turns out that in relation to the problems of determining the word similarity and word analogies, this approach can increase the accuracy of their solution. Experimental studies, the results of which are presented in this work, show that this effect is not observed in solving the problem of document classification. Removing projections to the first directions leads to a decrease in the classification accuracy. At the same time, the traditional approach, which removes projections to the last principal directions, in most cases gives the best result.
Low-Threshold Production of Peer-to-Peer Lecture Films
Authors:   University of Applied Sciences, Wilhelminenhofstraße 75A, 12459 Berlin, Germany, Pfennig Anja , Maier-Rothe Jörg
Published: January 2021

Lecture videos are more and more implemented in higher education to be used widely by students providing an audio and visual stimulus. To attract students and become a fully accepted learning material these videos need to be of a certain standard. An important factor to the success of these videos is to involve students directly into the concept and making-of (peer-to-peer approach). The peer-to-peer approach is an important aspect in terms of project success, quality of the content and lecture video quality because students` needs and their perspective on teaching material are directly included in the videos. To encourage lecturers this paper provides a short guidance to look at basic needs and requirements of the lecture film production and “just get started”. Good lecture videos may successfully be produced with low threshold.
The Effectiveness of Peer-to-Peer Lecture Films in Inverted Classroom Teaching Scenarios
Authors:   University of Applied Sciences, Wilhelminenhofstraße 75A, 12459 Berlin, Germany, Pfennig Anja
Published: January 2021

At HTW Berlin, Germany first year mechanical engineering students are taught material science as one of the fundamental courses with high work load in a blended learning environment with flipped classroom elements. Therefore peer-to-peer lecture films were established as source of theoretical background knowledge provided for self-study periods. Because the teaching method “inverted classroom” and class results directly relate to the quality of the video material one of the columns of lecture video production is the involvement of students in the lecture film production. First year students directly benefit from their fellow student learning experience, needs and perspective on teaching material. From the lecturers perspective students were generally more active and better prepared during class resulting in better grades. Practice examples introduce and evaluate both, the teaching method and videos.

One of the challenges of an intelligent tutoring system (ITS) is adapting the difficulty level of the questions posed to the student to suit the student’s academic level. Our study examines the task of adjusting the system’s level of challenges to the level of the learner and addresses the questions of how best to do so and whether there is any benefit from such adjustment. To answer these questions, we developed reading comprehension courseware that includes three adaptive algorithms for adjusting the level of the questions presented to the students: the random selection algorithm, the Q-learning based algorithm, and the Bayesian inference algorithm. We conduct a real-world experiment in which real high school students used the courseware to improve their reading comprehension skills. In order to compare and evaluate the performance of the algorithms, the courseware used by each student utilized one of the three adaptive algorithm alternatives. Our results demonstrate that when considering all of the students, there was significant improvement (learning gain) using each of the methods.

Published: January 2021

One of the frequently occurring tasks during the development of warehouse management systems is the implementation of routing algorithms of some kind. Whether it is for routing workers during order picking, delivery vehicles or company representatives, this task has proven to be challenging in the technical as well as the social sense. In other words, the task is heavily dependent on various general and company-specific constraints and it directly dictates the way employees should do their job. This paper describes a strategic approach to the development and gradual integration of such algorithms which makes sure that all constraints are satisfied and, more importantly, ensures that route suggestions are viewed by the employees as a helpful tool rather than a threat to their job. In the first part of this paper, the approach is described and evaluated on a warehouse representative routing problem through a real-world case study in a medium-to-large warehouse. In the second part, the same approach is adapted to a delivery vehicle routing problem for a smaller retailer company. In both cases, routing efficiency almost doubled in comparison to previous approaches used by the companies. The most important factors of the implementation and integration stages as well as the impact of the changes on employee satisfaction are aggregated, analysed in detail, and discussed throughout different stages of development.
Electronic Business and Trust – Anything is Possible
Authors:   University of Turku, P.O. Box 181, 28101 Pori, Finland, Sirkemaa Seppo J.
Published: January 2021

Electronic Business is based on trust between the seller and the buyer. Trust is not an issue if seller and buyer know each other, and they have an existing business relationship. However, when there are no earlier experiences, when the customer is not familiar with the vendor or the products and services are new – trust can be challenging. If there is no knowledge whether the vendor is trustworthy, the buyer is trying to find different kinds of reviews and experiences from other customers to make sure the buying decision is right. Here we look at how these cues could be made available, and in this way adding value to both vendor and buyer. Ultimately, better information increases trust and helps in developing successful business.

Peripheral nerve blocks and ultrasound navigation
Authors: Koryachkin V. A.
Published: January 2021

The use of ultrasound in anesthetic practice has contributed to the creation of new techniques for blocking peripheral nerves (PEC I, PEC II, TAP-block, QL-block, IPACK). At the same time, the creation of new blocks with ultrasound navigation deepens the gap between more experienced anesthesiologists and their younger colleagues who prefer to avoid the use of regional anesthesia. A way out of this situation seems to us to create and introduce into practice a list of basic methods of regional anesthesia, which can provide anesthesia during the most frequently performed surgical interventions. We believe that there is every reason to change the paradigm many blockades for the elite to several blockades for all.

Published: January 2021

Early diagnosis of psoriatic arthritis (PsA) is necessary for timely treatment and prevention of the disease progression with destruction of the joints. In most patients, comorbid PsA develops many years after the debut of the skin process. Consequently, the main role in timely diagnosis of PsA is played by a dermatologist, who is able to identify its initial signs and refer the patient to a rheumatologist. Early initiation of systemic therapy with the use of modern biological agents for progressive psoriatic arthritis and severe psoriasis can prevent the development of irreversible disability.

Published: January 2021

Pemanfaatan ikan hiu sebagai bahan baku produk olahan perikanan dapat menyebabkan berkurangnya populasi ikan hiu yang juga rentan akan kepunahan. Ikan hiu pada umumnya diperdagangkan dalam bentuk sirip, daging ikan yang diasinkan dan direbus, minyak ikan serta sebagai bahan subtitusi pada pakan hewan sehingga proses identifikasi menggunakan metode berbasis morfologi dan meristik sulit dilakukan. Sebagai alternatif proses autentikasi bahan baku produk olahan ikan hiu adalah menggunakan teknik DNA mini barcodes. Penelitian ini bertujuan untuk merancang dan mengaplikasikan primer DNA mini barcodes yang spesifik terhadap tiga species hiu terancam punah yang masuk dalam daftar CITES (Sphyrna lewini, Alopias pelagicus, Carcharhinus falciformis) serta mengaplikasikan pada berbagai produk olahan ikan hiu. Tahapan penelitian yang dilakukan meliputi koleksi sampel produk olahan perikanan, perancangan primer spesifik, isolasi DNA, pengujian kualitas dan kuantitas DNA, amplifikasi DNA, dan sekuensing. Berbagai produk olahan komersial berhasil diamplifikasi oleh primer spesifik yaitu pada target 300 pb (S. lewini), 285 pb (A. pelagicus) dan 352 pb (C. falciformes). Hasil sekuensing DNA sampel menunjukkan bahwa spesies teridentifikasi adalah S. lewini, A. pelagicus, C. falciformes dan Hemigaleus microstoma dengan kemiripan 99-100%. Hal tersebut menunjukkan bahwa masih terdapatnya pemanfaatan ikan hiu yang dilindungi secara ilegal, sehingga perlu penerapan regulasi yang lebih ketat untuk melestarikan spesies-spesies hiu yang terancam kepunahannya.
Managerial Ability and Future Banking Performance: The Role of Book-Tax Differences as Moderator
Authors: Herianti Eva , Suryani Arna , Marundha Amor
Published: January 2021

Research aims: This study aims to examine and analyze the effect of managerial ability on future banking performance moderated by book-tax differences.Design/Methodology/Approach: The research samples were banks listed on the Indonesia Stock Exchange from 2014 to 2018. A purposive sampling technique was conducted to collect 108 samples of future banking performance (t+1) and 81 samples of future banking performance (t+2). The data were then analyzed using eviews version 10 with the ordinary least square.Research findings: The results showed that managerial ability positively and significantly affected future banking performance (t+1 and t+2), while book-tax differences could reduce the effect of managerial ability on future banking performance (t+1 and t+2).Theoretical contribution/Originality: This study has provided implications to the literature that managers use their abilities to achieve sustainable competitive advantage through efficient and effective use of resources. Managers need an understanding of the relationship between resources, their abilities, competitive advantages, and future earnings achievement.Practitioner/Policy implication: Since managerial ability can increase future banking performance, this study’s results may affect how companies produce managerial ability through efficient use of inputs to produce optimal output that is useful for long-term banking performance.Research limitation/Implication: The conclusion is drawn based on various proxies to measure the managerial ability, book-tax differences, and future banking performance. Further research can develop the managerial ability proxies besides those proposed by Garcia-meca Garcia-Sanchez (2018).

Fenología reproductiva de tres especies de Pristimantis en un bosque de niebla andino
Authors: Ramírez-Pinilla Martha Patricia , Granados-Pérez Yamile
Published: January 2021

Estudiamos la fenología reproductiva en tres especies de Pristimantis que coexisten en un bosque de niebla tropical andino en la cordillera Oriental de Colombia. Las poblaciones estaban constituidas principalmente por juveniles, numerosos machos adultos, y pocas hembras adultas reproductivas, por lo que la proporción operacional de sexos estuvo muy sesgada hacia los machos, mas no así la proporción poblacional. La media de la longitud rostro-cloaca fue mayor en las hembras adultas que para los machos adultos, así como el tamaño mínimo  e madurez sexual, lo que indica que las hembras maduran con tamaños corporales más grandes que los machos y explica el sesgo en la proporción operacional de sexos. Los análisis histológicos de los testículos revelaron la presencia de esperma en casi todos los machos recolectados, lo que significa que son un recurso permanente para  a reproducción en las tres especies estudiadas. Los cuerpos grasos abdominales de los machos no mostraron variaciones temporales significativas, ni una relación con las lluvias. Se observaron tres patrones de actividad Reproductiva: 1) actividad reproductiva continua en P. miyatai; 2) actividad reproductiva en las estaciones lluviosas y reclutamiento de juveniles en las siguientes estaciones secas en P. merostictus, y 3) actividad reproductiva principalmente durante el segundo semestre del año y reclutamiento de juveniles en la siguiente estación seca (P. uisae). Los análisis de la actividad reproductiva y el reclutamiento de juveniles revelaron una superposición temporal entre las especies de Pristimantis, lo que sugiere que la fenología reproductiva no juega un papel importante en la segregación temporal de estas especies de anuros. Sin embargo, los diferentes patrones de reproducción podrían representar una estrategia que reduce la aglomeración de ranitas en los microhábitats de crecimiento, facilitando así la coexistencia entre taxones que potencialmente compiten.

Published: January 2021

Currently, the use of agro-industrial waste represents a viable alternative for obtaining valuable compounds that, in the case of biorefineries, is an opportunity for improvement. In this context, the aim of our study was to determine the flavonoid content and the antioxidant capacity of 30 byproducts from fruit processing in Colombia and propose possible applications. We analyzed the antioxidant capacity of the ethanolic extracts from each byproduct using the ferric reducing antioxidant power (FRAP) and the reducing power of antioxidant activity (RPAA) assays, as well as the oxygen radical absorbance capacity (ORAC) test. We found that tree tomato peels and stem and peach peels had a high flavonoid content, with values greater than 8,271.82 ± 702.70 μg quercetin per gram of dry sample. We also found that mango (22,676.57 ± 759.71 μg TE1/g Sdb, 3,692.38 ± 92.67 μg GAE/g Sdb), soursop (22,117.13 ± 754.94 μg TE1/g Sdb, 4,858.79 ± 156.71 μg GAE/g Sdb, 14,713.39 ± 757.95 μg TE2/g Sdb), grape (17,027.85 ± 765.11 μg TE1/g Sdb, 13,395.15 ± 659.31 μg TE2/g Sdb), peach peels (17,910.21 ± 1,424.33 μg TE2/g Sdb) and seeds (4,316.46 ± 112.00 μg GAE/g Sdb, 20,093.32 ± 1,317.93 μg TE2/g Sdb), and grape stalk (3,552.26 ± 31.63 μg GAE/g Sdb) showed a high antioxidant capacity in the different tests performed. Our results demonstrate that fruit byproducts have potential use in the pharmaceutical,  ood, and cosmetic industry due to  heir flavonoids content and their high antioxidant capacity.

Цель. Изучить в эксперименте на крысах интеграцию с костью металлических имплантатов из нержавеющей стали с алмазоподобным углеродным (DLC) покрытием. Материал и методы. Эксперимент проведен на 48 белых крысах-самцах в возрасте 6 месяцев. Животным имплантировали в метафизарные дефекты бедренной кости (диаметр 2 мм и глубина 3 мм) имплантаты из стали и стальные имплантаты с DLC-покрытием (по 24 крысы в контрольной и опытной группах). На поверхность стального имплантата наносили DLC-покрытие из отфильтрованных потоков вакуумно-дуговой плазмы. Материал покрытия не содержал примесей металлов и водорода. Нанотвердость нанесенного на образец покрытия составляла от 30 до 40 ГПа. Толщина DLC-покрытия составляла не менее 1 мкм. Эвтаназию крыс проводили через 7, 14, 30 и 90 дней после операции путем введения летальной дозы тиопентала натрия (90 мг/кг внутримышечно). Ремоделирование кости вокруг имплантатов исследовали гистологическими методами с морфометрической оценкой остеоинтеграции (контакт костной ткани с имплантатом в процентах). Результаты. Алмазоподобное углеродное покрытие на стальных имплантатах обладает высокими адгезионными качествами, о чем свидетельствует прикрепление клеток к поверхности в течение 7 дней после имплантации и формирование вокруг них костной ткани через 14 дней. Вокруг стальных имплантатов зафиксировано образование прослойки из соединительной ткани с участками костной ткани. Выявлено, что за весь период исследования вокруг имплантатов из стали с DLC-покрытием процент остеоинтеграции был выше по сравнению с имплантатами без покрытия: на 14-й день – в 2,6 раза, на 30-й день – в 2,1 раза, на 90-й день – в 1,5 раза. Заключение. Алмазоподобные углеродные покрытия на стальных имплантатах являются перспективным материалом для использования в ортопедии и травматологии благодаря биосовместимости, остеоинтеграции и отсутствию негативного ремоделирования прилегающей костной ткани. Научная новизна статьи Впервые в эксперименте изучена перестройка кости вокруг имплантатов с разработанным алмазоподобным углеродным покрытием. Установлено, что использованное покрытие обладает биосовместимостью и высокими показателями остеоинтеграции.

Лечение грыж является одним из самых древних разделов хирургии, и по настоящее время его развитие стремительно продолжается. В последние годы в арсенале хирургов появился целый ряд новых технологий, которые нашли свое место и в герниологии. Несмотря на бурное развитие хирургии грыж, сохраняется ряд дискуссионных вопросов. Не определена роль предоперационных методов обследования в алгоритме выбора метода лечения. Не существует однозначного мнения относительно пространств, в которые следует имплантировать сетчатый имплант, а также того, насколько выполнимы и целесообразны малоинвазивные методы. Кроме того, нет консенсуса по вопросам терминологии, используемой в современной герниологии. В данной статье затронуты эпидемиологические и исторические аспекты хирургии вентральных грыж, рассмотрены актуальные представления об анатомии передней брюшной стенки, современная терминология и классификации, описаны методы предоперационной подготовки и обследования пациентов с вентральными грыжами, показания к хирургическому лечению, разобраны существующие хирургические опции. На сегодняшний день остается актуальным проведение поисков наиболее физиологичных и функциональных методов лечения вентральных грыж, обеспечивающих минимальный риск рецидива и осложнений и повышающих качество жизни пациентов.
Increasing ship energy efficiency with diesel-electric propulsion system

Published: January 2021

Today, the goal of reducing fossil fuel consumption and increasing the use of renewable energy is one of the most important issues in the maritime field. Regulations created by IMO in order to prevent environmental and air pollution in the maritime field have increased its effect day by day and made it necessary to move away from conventional systems and turn to alternative systems. Although studies in the area of using fully electric marine vehicles or using fully renewable energy systems are also ongoing, they are not preferred due to the high costs and lack of sustainability. While the use of Diesel Electric (DE) Propulsion System in marine vehicles is one of the alternatives in this field, it may be the most efficient choice with the improvements made on this system. The aim of this study is to examine the increase in ship energy efficiency using diesel-electric propulsion systems rather than the original ferry system.In the study, the historical development of the DE Propulsion System was investigated and other studies on the subject were examined. Detailed navigation data of a ferry using fossil fuels in the Gulf of Izmir were recorded, and a case study was carried out to examine the status of this ship's DE Propulsion System by using data such as engine load and fuel consumption. According to the results obtained, it has been revealed that using the DE Propulsion System can be much more efficient in terms of fuel consumption and emissions. It has been observed that the system provides benefits in terms of reliability and reduction of noise pollution. For future studies, it may be aimed to provide the ferry to be charged from the port and to increase the benefits of the system by using renewable energy.

Authors: Bayraktar Murat , Cerit Güldem A.
Published: January 2021

Many improvements are performed in the maritime industry to ensure sustainability and energy efficiency. The use of hybrid propulsion systems (HPS) in marine vessels constitutes one of the developments in this field. In this study,both economic and environmental benefits are targeted. The study aims to reduce the high fuel consumption of the engine per unit power at low loads and minimization of emissions by sourcing them from main engine by HPS. Overcoming the limitations of Annex VI (Prevention of Air Pollution from Ships) of International Convention for the Prevention of Pollution from Ships (MARPOL) are desired and the research hopes for a beneficial result on Energy Efficiency Measures such as Energy Efficiency Operational Indicator (EEOI). A comprehensive study is accomplished on the hybrid propulsion system components and the keywords used in the literature review are revealed. Furthermore, the articles that have “efficiency”, “vessel”, “propulsion” and “marine” topics published in Web of Science (WOS) between 1975-2020 are examined and 44 studies are obtained. The studies that have been reached are analyzed and interests of them are collect under the 18 heading and the focal point of each study is highlighted in article. According to the results, the hybrid system provides low fuel consumption, minimizes emissions and  costs, complies with the regulations of the International Maritime Organization, uses renewable energy sources, encourages the use of electric motors in addition to internal combustion engines, increases the efficiency of energy storage systems among other things. This article will be a significant resource for academicians, experts and companies on the Hybrid propulsion system in setting their focus.

Is It “True” Pain? Pain Treatment Discharge Planning for Seriously Injured Patients
Authors: Aronowitz Shoshana V. , Richmond Therese S. , Compton Peggy , Jacoby Sara F.
Published: January 2021

Background: The United States is experi­encing an opioid overdose crisis accounting for as many as 130 deaths per day. As a result, health care providers are increas­ingly aware that prescribed opioids can be misused and diverted. Prescription of pain medication, including opioids, can be in­fluenced by how health care providers per­ceive the trustworthiness of their patients. These perceptions hinge on a multiplicity of characteristics that can include a patient’s race, ethnicity, gender, age, and present­ing health condition or injury. The purpose of this study was to identify how trauma care providers evaluate and plan hospital discharge pain treatment for patients who survive serious injuries.Methods: Using a semi-structured guide from November 2018 to January 2019, we interviewed 12 providers (physicians, nurse practitioners, physician assistants) who pre­scribe discharge pain treatment for injured patients at a trauma center in Philadelphia, PA. We used thematic analysis to interpret these data.Results: Participants identified the impor­tance of determining “true” pain, which was the overarching theme that emerged in analysis. Subthemes included perceptions of the influence of reliable methods for pain assessment, the trustworthiness of their patient population, and the consequences of not getting it right.Conclusions: Trauma care providers de­scribed a range of factors, beyond patient-elicited pain reports, in order to interpret their patients’ analgesic needs. These included consideration of both the risks of under treatment and unnecessary suffering, and overtreatment and contribution to opi­oid overdoses.Ethn Dis. 2021;31(1):139- 148; doi:10.18865/ed.31.1.139
Step 0: The Spirit of Inquiry

It stands to reason that competency in every area of practice, including the evidence-based practice process, improves through participation in the practice. But before engagement in the evidence-based practice process can occur, Melnyk and Fineout-Overholt1 assert, there must be a “spirit of inquiry.” This column describes strategies to spark and cultivate a spirit of inquiry for evidence-based practice and barriers that can dampen the spirit.
When Your Breasts Might Not Work: Anticipatory Guidance for Health-Care Professionals
Authors: Spatz Diane L. , Miller Jodie
Published: January 2021

There are many factors that can negatively impact a mother developing a copious milk supply and being able to exclusively breastfeed her infant. In this article, we present two case exemplars (glandular hypoplasia and breast reduction surgery) to illustrate that not all mothers may be able to develop a full milk supply, and that families should receive appropriate prenatal anticipatory education and guidance from childbirth educators and all health-care providers. Important considerations include the value of every drop of milk that the mother is able to produce, treating the milk as an important medical intervention, and developing a plan with the family for supplementation so the infant can receive adequate intake for growth.

Published: January 2021

Background: In the past six months, Croatia faced a short lockdown and a slow return to most hospitals’ everyday activities. During the lockdown, our center, as a part of the University Hospital Centre specialized for solid cancer, was enabled to maintain most of the routine practices with the one-month colonoscopy exception. Aim: To determine the oscillation in the number of endoscopies and colorectal surgery for 13 months (six months pre and post COVID-19 lockdown). Materials and methods: From August 1st, 2019, until August 31st 2020, the hospital analytics determine the number of colonoscopies, screening colonoscopies, and surgeries. Results: During the given period number of detected and operated colorectal cancers was stable, except for April, when we mostly did not perform colonoscopies. Conclusion: We maintained a pre-COVID-19 pace in colorectal cancer treatment, colonoscopies, and colorectal surgery after epidemiological guidelines for colonoscopies and colorectal surgery were applied, owing to the relatively stable overall epidemiological situation.
Comparison of two planning techniques (FiF/IMRT) for postoperative radiation therapy of prostate cancer
Authors:   Medical Physics Department, University Hospital Rijeka, Rijeka, Croatia, Obajdin Nevena
Published: January 2021

Introduction: Within the past two decades, we made significant progress in radiation therapy for prostate cancer. At UH Rijeka IMRT became the technique of choice for radiation therapy following radical prostatectomy since 2016. Previously, an advanced 3-DCRT technique using the field-in-field (FiF) method was used for dose distribution optimization around target volumes and organs-at-risk. This research has been performed to investigate the influence of planning technique choice (FiF or IMRT) on coverage of target volumes with prescribed dose and organs-at-risk sparing. Materials and methods: Comparison of dose distributions calculated using FiF and IMRT techniques was performed retrospectively for ten patients who underwent postoperative radiotherapy. The prescribed dose for all patients was delivered using IMRT, and for this research, we also calculated dose distributions using the FiF technique. For FiF and IMRT techniques, we used linear accelerator photon beams. To determine the influence of planning technique on dose distribution parameters related to target volumes (GTV, CTV, PTV1, PTV2) were analyzed. For organs-at-risk sparing evaluation (rectum, bladder, femoral heads), we used dose-volume constraints. Results and discussion: The analysis of parameters related to target volumes has shown that most of them had no statistically significant difference (V100%(GTV), V100%(CTV), V95%(PTV2), V95%(PTV1)). For both planning techniques, internationally set dose constraints were achieved. Statistically, we found a significant difference for V100%(PTV2), p=0,000534, and V100%(PTV1), p=0,042944 in favor of IMRT. A statistically significant difference (p=0,045966) was found for the volume of the rectum, which receives 40Gy, and for the volume of femoral heads, which receives 30Gy (p=0,000385), where the sparing is better for IMRT. For dose-volume constraints related to the bladder, no statistically significant differences were found. Conclusion: Results of this research show a statistically significant difference for V100% target volume coverage for PTV1 and PTV2, with better dose coverage accomplished by IMRT. Concerning organs-at-risk sparing, a statistically significant difference in favor of IMRT was found for rectum volume, which receives 40Gy. Expectedly, IMRT was superior to the FiF technique. However, differences between the two planning techniques were relatively small, which points to the fact that the FiF technique is viable as a technique of choice.
