Heart Transplantation in Singapore
Authors: Sivathasan Cumaraswamy
Published: October 2022

Introduction: The status of heart transplantation in Singapore is reviewed in this article.

Materials and Methods: The database of 40 consecutive heart transplantations from July 1990 through December 2007 is reviewed retrospectively. The data is compared with the 2008 registry data of the International Society for Heart and Lung Transplantation (ISHLT).

Results: The average age of recipients was 45.3 years. Ages ranged from 14 to 64 years. Ischaemic cardiomy- opathy (52.5%) and dilated cardiomyopathy (42.5%) were the major indications. From 1990 to 1999, 50% of the donors sustained brain death from road traffic accident, 25% from cerebrovascular accident and 25% from falling from height, whereas the cause of brain death in the donors from 2000 to 2007 was 33%, 47% and 9.5%, respectively. The average donor age increased from 28.3 to 38.1 years. The significant morbidities in the recipients were hypertension, cytomegalovirus (CMV) infection, cardiac allograft vasculopathy and renal dysfunction. Thirty- two required treatment for hypertension. 67.5% developed CMV disease requiring treatment. Cardiac allograft vasculopathy was diagnosed in 10. Rising creatinine levels reaching over 2.5 mg/dL was seen in 7. Three required renal dialysis. Epstein-Barr virus related lympho prolifera- tive disorder occurred in 2 patients. One patient developed adenocarcinoma of stomach. The 30-day mortality was 10% and half life was 10 years. Cardiac allograft vasculopathy and sepsis caused 41.7% of mortality each. 11.7% of the mortality was due to cerebrovascular accident.

Conclusion: The status of heart transplantation in Singapore is comparable to the ISHLT registry data. Transplant provides excellent early survival of 80%; however, the expected half life is around 10 years after cardiac transplantation. The late mortality is mainly caused by cardiac allograft vasculopathy (CAV) and renal failure. More effort and research needs to be directed towards these issues to improve the long-term results.

The Role of Research in Transplantation
Authors: Calne Sir Roy Y
Published: October 2022

In the past 50 years, organ transplantation has developed from an improbable laboratory exercise to a major therapeutic success. The surgical problems of organ grafting have, for the most part, been solved. Rejection of grafts is now partially understood and usually controllable by powerful immunosuppressive drugs. A steady improvement in patient outcome, especially following the introduction of cyclosporin as an immunosuppressive agent has resulted in a worldwide shortage of organs for transplantation. This has provoked serious ethical dilemmas in every country. These matters are summarised in the following text.

Leptin and Bone Mineral Density in Haemodialysis Patients
Authors: Yilmaz Abdulkerim , NUR Naim , Turgut Bulent
Published: October 2022

Introduction: There are very few data about relations between leptin and bone mineral density (BMD) in regular haemodialysed patients. We aimed to examine the relationship of serum leptin levels with BMD values in dialysed patients. We also assessed whether leptin is a significant predictor of BMD in haemodialysed patients.

Materials and Methods: Leptin levels were studied using commercially available kits and BMD values were calculated using dual energy X-ray absorptiometry (DEXA) at femoral neck and distal radius in 74 (30 men and 44 women ) haemodialysis patients.

Results: BMD values at the femoral neck and distal radius did not differ significantly between the 2 genders. BMD at the distal radius correlated positively with bone alkaline phosphatase (BAP) (r = 0.503, P = 0.005) in male patients and correlated positively with phosphorus (r = 0.343, P = 0.02) in female patients. The time on dialysis treatment was longer in men (59 ± 48 vs 44 ± 41) but the difference was not statistically significant. Leptin levels were negatively correlated with BMD at the distal radius (r = -0.250 and P = 0.03) in all patients. Serum leptin levels were also correlated with body mass index (BMI) in all the patients (r = 0.749 and P = 0.001) and in both genders (r = 0.653 and P = 0.001 in women, r = 0.704 and P = 0.001 in men). In multivariate regression analysis, it was found that leptin level was not an independent determinant of BMD at all skeleton sites measured.

Conclusions: There was significant difference between the 2 genders with reference to leptin levels, BMI, phosphorus and creatinine. Serum leptin levels are not significant predictors of BMD in the current study.

Neurobiology of Schizophrenia Spectrum Disorders: The Role of Oxidative Stress
Authors: Wood Stephen J , Yücel Murat , Pantelis Christos , Berk Michael
Published: October 2022

Mitochondrial dysfunction and oxidative stress are increasingly implicated in the pathophysiology of schizophrenia. The brain is the body’s highest energy consumer, and the glutathione system is the brain’s dominant free radical scavenger. In the current paper, we review the evidence of central and peripheral nervous system anomalies in the oxidative defences of individuals with schizophrenia, principally involving the glutathione system. This is reflected by evidence of the manifold consequences of oxidative stress that include lipid peroxidation, protein carboxylation, DNA damage and apoptosis – all potentially part of the process of neuroprogression in the disorder. Importantly, oxidative stress is amenable to intervention. We consider the clinical potential of some possible interventions that help reduce oxidative stress, via augmentation of the glutathione system, particularly N-acetyl cysteine. We argue that a better understanding of the mechanisms and pathways underlying oxidative stress will assist in developing the therapeutic potential of this area.

PHYSICS INFORMED NEURAL NETWORKS FOR TWO DIMENSIONAL INCOMPRESSIBLE THERMAL CONVECTION PROBLEMS
Authors: AYGUN Atakan , KARAKUS Ali
Published: October 2022

Physics-informed neural networks (PINNs) have drawn attention in recent years in engineering problems due to their effectiveness and ability to tackle problems without generating complex meshes. PINNs use automatic differentiation to evaluate differential operators in conservation laws and hence do not need a discretization scheme. Using this ability, PINNs satisfy governing laws of physics in the loss function without any training data. In this work, we solve various incompressible thermal convection problems, and compare the results with numerical or analytical results. To evaluate the accuracy of the model we solve a channel problem with an analytical solution. The model is highly dependent on the weights of individual loss terms. Increasing the weight of boundary condition loss improves the accuracy if the flow inside the domain is not complicated. To assess the performance of different type of networks and ability to capture the Neumann boundary conditions, we solve a thermal convection problem in a closed enclosure in which the flow occurs due to the temperature gradients on the boundaries. The simple fully connected network performs well in thermal convection problems, and we do not need a Fourier mapping in the network since there is no multiscale behavior. Lastly, we consider steady and unsteady partially blocked channel problems resembling industrial applications to power electronics and show that the method can be applied to transient problems as well.

Published: October 2022

Artan plastik kullanımı ve kullanılan plastiklerin bir süre sonra atık olarak birikmesi günümüzün başlıca sorunlarındandır. Atık plastiklerin yeniden değerlendirilmesi için termokimyasal dönüşüm prosesleri oldukça verimlidir. Atık plastiklerin tek başına ve çeşitli yerli kömürler ile birlikte gazlaştırılması sayesinde yakıt olarak kullanıma uygun CO, CH4 ve bir enerji taşıyıcısı olan H2 içeren sentez gazı üretimi mümkündür. Bu amaçla yapılan çalışmada, Himmetoğlu ve Seyitömer bitümlü şeylleri ile plastik atık karışımı (%56 polietilen, %28 polipropilen ve %16 polistiren) gazlaştırılmıştır. Deneysel çalışmalar, 4 cm iç çapında ve 110 cm boyundaki kuvars camdan imal edilen laboratuvar ölçekli akışkan yataklı sistemde gerçekleştirilmiş olup akışkanlaştırıcı gaz olarak hava ve gazlaştırıcı akışkan olarak da su buharı kullanılmıştır. Sıcaklığın (750◦C, 800◦C, 850◦C), su buharı akış hızının (5-10-15 g/dak) ve beslemedeki plastik oranının (%40 ve %70) sentez gazındaki H2 ve CH4 konsantrasyonuna etkileri incelenmiştir. 5-10 g/dak akış hızındaki su buharı kullanımı Himmetoğlu bitümlü şeylinin ve karışımlarının gazlaştırılması için uygundur. Seyitömer bitümlü şeyli ve karışımlarının gazlaştırılmasında ise 10-15 g/dak olacak şekilde daha yüksek akış hızlarının uygun olduğu görülmüştür. Himmetoğlu ve Seyitömer bitümlü şeyllerine %40 ve %70 oranında plastik atık karıştırıldığında üretilen sentez gazındaki H2 konsantrasyonu azalırken CH4 konsantrasyonu artmıştır. Çalışma sonucunda, en yüksek H2 konsantrasyonu %21,33 (750◦C - 10 g/dak- %60 Himmetoğlu bitümlü şeyli ve %40 plastik beslemesi) ve en yüksek CH4 konsantrasyonu ise %74,71 (850◦C - 10 g/dak- %30 Himmetoğlu bitümlü şeyli-%70 plastik atık) olarak elde edilmiştir. Üretilmesi planlanan sentez gazının kullanım alanına göre sıcaklık, su buharı akış hızı ve besleme karışım oranı değiştirilerek uygun çalışma koşulları belirlenebilir.
GuideDogNet: A Deep Learning Model for Guiding the Blind in Walking Environments
Authors: Hwang Yunseo , Yoon Taeseon , Park Kyuyong
Published: October 2022

A guide dog is a critical companion for the blind, which enables independent travel of the blind. However, due to the costly and time-consuming training process, only 1.7% of the blind who wish to adopt a guide dog can take it. In order to alleviate this social problem, previous studies have suggested several blind guiding systems heavily based on hardware devices, such as GPS(Global Positioning System), RFID(Radio-Frequency Identification), and ultrasonic devices. However, those techniques lack administrative feasibility to use in real-world environments. Moreover, those techniques are deficient in warning of obstacles, which makes the system non-user-friendly. To guide the blind universally and provide accurate information about the obstacles without cumbersome devices, we propose a novel deep learning-based blind guiding system, GuideDogNet. The proposed system consists of an object detection network, depth prediction network, and post-processing module. To provide user-friendly outputs for the blind, we propose a rule-based post-processing module that outputs the label, direction, and distance of the obstacles by combining the results of the object detection network and the depth prediction network. We achieved an mAP of 67.8 on the AI Hub Sidewalks dataset which is publicly available. To the best of our knowledge, this is the first attempt at a deep learning-based blind guiding system.

IoT and AI Based Integrated System to Detect Crop Diseases and Deficiency of Nutrients in a Large Farm
Authors: Kar Shraman , Willert Jeffrey
Published: October 2022

The world population is expected to increase by 2 billion by 2050. A person dies of hunger every 3.6 seconds. The UN has come up with a list of 17 goals to make the world a better place and ending hunger comes at second. A 119% increase in yield is required by 2050 to sustain life. As the amount of land cannot be increased, the only way is by increasing crop yield from the same land. Research has shown that disease and nutrient deficiency-related yield losses have cost the world 60% of global agricultural productivity.  Diagnosis of the disease and nutrient deficiency in a large farm is very difficult because of the number of crops. This project, “CropMates”, aims to identify crop diseases in a vast area of farmland by first surveying the acreage using a GPS-enabled drone. The camera-fitted drone captures video and pictures of the farm while flying over the field. A deep learning algorithm is created to identify leaves from these pictures. Another deep learning-based algorithm using AlexNet architecture is trained with 38 different classes of diseases on 87,000 images of leaves to identify diseases from these leaves.  An Artificial Neural Network is developed and is trained on 20,000 data points to identify nutrient deficiencies in the soil from IoT-enabled sensors put across the farm. An app is built to show the results and to recommend the type and amount of pesticide and fertilizer for optimum crop yield.
Health Habits and Attitudes of Adolescents during the COVID-19 Pandemic
Authors: Reicher Eugene , Ricci Jessica
Published: October 2022

The ongoing COVID-19 pandemic has significantly impacted adolescent health and lifestyle. This study aims to evaluate adolescent physical and mental health, and behaviors and attitudes related to the COVID-19 pandemic. We surveyed 7-12th grade students in one Los Angeles independent suburban school (Sierra Canyon School) and statistically analyzed their anonymous responses. Two surveys were administered: Survey 1 in March 2021, when the school had been closed to in-person learning for approximately one year, and Survey 2 in May 2021, about six weeks after the school had opened for voluntary in-person learning. Survey 2 included additional demographic questions about gender, political affiliation, and race/ethnicity to evaluate the correlation between these factors and COVID-related issues. We used linear regression to analyze correlations between parameters characterizing various aspects of health habits, attitudes, and behaviors and evaluated the statistical significance of the differences using Student’s t-test. We were most interested in analyzing the impact of school reopening by comparing the data in Survey 1 to Survey 2. The main result is that the return to in-school learning had a pronounced positive effect not only on the education quality but also on a number of various aspects of adolescent health and behavior. In addition, the survey showed interesting, sometimes surprising, correlations between distinct parameters, for example, the effects of gender on physical and mental health; or political affiliation on COVID-related attitudes and behavior.
Music With a Mood Opposite to The Movie Scene and Its Effects on Emotions
Authors: Keller Owen , Talarczyk Patricia
Published: October 2022

Music with a mood that does not match the movie scene is a form of film music that has been experimented with and explored over time. It has been recognized to have varying effects on audiences, specifically on mental processes like perceptions and moral judgment. One goal of this research was to explore a more underexplored aspect of this kind of film music: the emotions of the audience. Furthermore, the main goal was to determine if music with a mood opposite to the movie scene would convey and amplify emotions of the audience. To study how emotions of audiences are impacted by music with a mood that does not match the mood of the movie scene, multiple clips from movies with either music that matched or mismatched their original scenes were chosen to have new music edited onto them. This led to two groups: matched and mismatched mood clips. From this point, a survey with questions about emotions felt per each clip was distributed to participants, who watched the clips live. After participants responded about emotions that they felt and the intensities of those emotions, their results were analyzed to determine that music with a mood opposite to the movie scene does amplify the emotions of the audience and can convey new emotions, though results for newly conveyed emotions varied from clip to clip.

Published: October 2022

Purpose: The purpose of this paper was to assess the influence of process innovation on the performance of coffee cooperatives in Kenya.

Methodology: A descriptive research design was applied. The target population was 525 coffee cooperative societies in Kenya registered with the Commissioner for Cooperatives and licensed by AFFA (Coffee Directorate) as at 30th of October 2016. The sample size was 227 respondents which was arrive at using stratified random sampling technique. Structured questionnaires were used to collect primary data. Descriptive statistic such as means scores and standard deviation and inferential statistics such regressions were used.

Findings: The study found that there was a positive relationship between process innovation and the performance of the coffee cooperatives (β=0.591, p=0.027). This implied that an improvement in the aspects related to process through which the firm operates relatively multiplies the performance outcomes of cooperatives in a positive manner.  Investing in process innovation was found to have the largest and most significant effect compared to investing in organization, marketing and product innovations.

Recommendation: The study recommends that for prioritization purposes, coffee societies should prioritize investing in process innovations compared to other innovations, especially if there a limited budget. Policy makers should ensure a favorable environment for process innovations.

Neolitik dönemden günümüze kadar tarihsel süreç içerisinde teknoloji ile sürekli kendisini yenileyen seramik hayatımızın her döneminde önemli bir yeri olmuştur. Başlangıçta işlevsel, kullanım eşyası olarak görülürken, günümüzde kendine özgü üretim teknikleri, plastik ve anlatım dili plastik sanatlar içerisinde çağdaş seramik sanatı tanımıyla yerini almıştır. İnsan kendi varlığını hissettiği anda nesneler ve boşluklarla çevrili olan dünyasını sorgulamaya ve yaşadığı dünyayı tanımaya çabalamaya başlar. Nesneleri algılamasını ve görmesini sağlayan tarih boyunca sanat, bilim, felsefe gibi birçok alanda kaşımıza çıkan boşluk kavramı, bulunduğu toplum içerisinde ve döneminde bulunduğu yapıya göre şekillenerek, farklı biçimlerde karşımıza çıkmıştır. Seramik sanatında ise boşluk kavramı hem mekân içerisinde kapladığı alan olarak, hem de kendi içerisinde estetik görüntü ögesi olarak kullanımı ile çok önemli bir yere sahiptir. Matematiksel bir yapı olan fraktal yapılar birbirinin tekrarı olarak, doğada matematiksel denklemlerle oluşan karmaşık bir yapıdır. Doğada kendiliğinden oluşan bu yapılar matematik alanında olmasına rağmen günümüzde birçok alanda kullanılmaktadır. Sanat alanında da birçok sanatçının kullandığı fraktal yapı, matematik ve sanatın birlikteliği ile yaklaşımlarla oldukça önemli bir ilişki sağlamaktadır. Benzer küçük parçalarının birbirinin tekrarı olarak bir araya gelmesiyle oluşan fraktal yapılar dolu ve boş alan ilişkinin en güzel örneklerini oluşturmaktadır. Bu çalışmada da seramik sanatçılarının eserlerinde boşluk kavramını fraktal yapı içerisinde kullanımı irdelenerek fraktal yapı ve boşluk kavramı ilişkisi üzerinde değerlendirme yapılmıştır.

La comunicación digital en los museos de moda españoles: análisis de la presencia en las plataformas de social media
Authors: Gonzalez Liendo Julio Alexander
Published: October 2022

El desarrollo de estrategias de comunicación digital en los museos ya no es una opción, sino más bien una obligación impuesta por las propias audiencias. Si bien, antes de la pandemia,  algunas instituciones museísticas habían comenzado sus incursión en redes sociales como Facebook, Instagram y, cuando mucho, Twitter, con la llegada del COVID19, se vieron empujadas a asumir el reto de comunicarse con mayor énfasis en las plataformas de social media. Así, instituciones como el Museo Nacional El Prado se apoderó de Tiktok y, a través de vistas a espacios hasta entonces desconocidos por los usuarios, recorridos guiados por los curadores del museo, hasta experiencias en vivo, logró generar mucha conexión con sus audiencias, convirtiéndose en un punto de referencia para otros museos, tanto en España como internacionalmente. Pero ¿qué está sucediendo con los museos de moda?, ¿cómo se están comunicando? Este trabajo de investigación tiene por objeto de estudio analizar, con un enfoque cualitativo, el uso que los museos de moda en España le dan a las redes sociales Facebook, Instagram y Twitter, dentro de sus estrategias de comunicación. Luego de un recorrido por las ocho instituciones museísticas dedicadas exclusivamente a la moda, entre enero y junio de 2022, se concluye que estos museos aún no emprenden, de manera significativa, estrategias de comunicación digital acordes a la nueva realidad de la comunicación y, por ende, su impacto en las audiencias sigue siendo escaso y poco atractivo.

Authors: Cruz Barbosa Jennifer Carolina
Published: October 2022

Actualmente existen diversas formas por medio de las cuales los museos comparten sus colecciones, datos y experiencias disponibles hacia el público. Todas ellas enriquecen la comunicación y la interacción museo – usuarios. A la oferta de contenidos, puede ser agregado el aprendizaje en línea.El e-learning es una modalidad formativa que tiene como principal cualidad la flexibilidad, ya que permite a los estudiantes el consultar los contenidos sin depender de la ubicación geográfica, horarios o un dispositivo en específico. Esto refleja una ventaja al momento en que la entidad u organización desea compartir temas referentes a sus exposiciones.El e-learning se compone de multimedia, diseño instruccional y un aula virtual. Para desarrollar correctamente estos factores, existen metodologías de trabajo (el modelo ADDIE), softwares (suite de Adobe, Captivate, Articulate) y plataformas digitales (Moodle, YouTube, Wordpress), al alcance.Los museos cuentan con diferentes recursos y temas que pueden ser compartidos a través de este proceso de enseñanza. La narrativa en la museografía aplicada puede ser traducida a la narrativa aplicada en contenidos de aprendizaje en línea. Estos contenidos deben ser desarrollados siguiendo objetivos de enseñanza, de retribución económica – publicitaria y de respuesta positiva por parte de los participantes.Entre los contenidos que se pueden desarrollar en el e-learning, se encuentran videos, SCORM (contenidos interactivos), recorridos virtuales, lecturas, MOOCs, cuestionarios, infografías, entre otros. Estos deben ser alineados con las finalidades, las capacidades y necesidades del museo.La aplicación del e-learning permite tener un repositorio de materiales interactivos y brinda un nuevo canal para empatizar con el público, y se convierte en una herramienta para analizar su consumo, ya que se podrán obtener datos cuantitativos y cualitativos sobre qué temas del museo son claros y de interés, y cuales necesitan una mejora en su desarrollo y presentación.La propuesta dependerá siempre de las viabilidades y limitantes del museo. La presente comunicación brindará las pautas necesarias para dar los primeros pasos de acercamiento hacia la digitalización y creación de contenidos de enseñanza en las instituciones culturales.

Si las colecciones del museo son lo que configuran su identidad, esta no es explicable sin un relato sólido, pero en la sociedad postcovid no basta con el relato, puesto que los museos son invisibles sin una estrategia digital bien dirigida, que necesita de la creación constante de contenidos digitales. En esta encrucijada entre entorno físico y virtual, y entre colecciones y contenidos digitales, ¿cómo somos capaces de gestionar toda esta información desde la perspectiva del patrimonio cultural?El Museu de la Vida Rural lleva a cabo un proyecto de publicación de sus colecciones etnológicas sobre el mundo rural catalán, pero añadiéndole un relato contemporáneo (la sostenibilidad) con una intención educativa. La publicación online de sus colecciones fue concebida en 2020 superando formatos analógicos clásicos como el catálogo, para imaginar nuevos productos online adaptados al entorno digital: exposiciones online, interactivos educativos, un buscador o un webdoc. Todos ellos tienen un hilo en común: son nuevas formas de presentar el patrimonio que alberga el Museo, una propuesta de nueva museología en línea para las colecciones.Estos proyectos de publicación han supuesto llevar a cabo trabajos de documentación de las colecciones focalizados en la experiencia del usuario, de creación de vocabularios controlados para la indización de los elementos patrimoniales y la recuperación de la información en línea, a la vez que ha sido necesario crear nuevos contenidos digitales. Este cambio metodológico ha ido acompañado de un proceso de transformación de las herramientas de gestión y publicación (software), pasando de MuseumPlus a Dédalo, siendo este el sistema de gestión del patrimonio cultural que permite la convergencia entre lo físico y lo virtual, las colecciones y los contenidos digitales, resolviendo así la cuadratura del círculo.
Nuevas narrativas para las colecciones online del Museu Nacional: optimización y sostenibilidad de contenidos digitales
Authors: Perez Pena Laia , Gumà Marques Montse
Published: October 2022

Mappings, realidad aumentada, realidad virtual, gigafotos, 3D… toda una serie de recursos que debemos planificar e integrar en un marco global, el de la estrategia digital del museo, y que tenemos que fundamentar con dos premisas principales: por un lado, tenemos que plantearnos unos recursos que enriquezcan la colección y que sean consultables desde cualquier canal, y, por otro lado, tenemos que pensar en su sostenibilidad. No debemos dejarnos llevar por la tecnología, sino por el tipo de contenido que tenemos o podemos generar, lo que queremos contar y a quien queremos contárselo. Todo ello, un reto.Hemos constatado que las páginas más visitadas de la web, después de las de información práctica, son las del catálogo online y, por tanto, hemos apostado por enriquecer la web de contenido sobre la colección con el objetivo de fidelizar usuarios, aumentar los usuarios recurrentes y reducir la tasa de rebote. Para hacerlo de una forma sostenible en el tiempo, hemos procurado la optimización de los recursos, tanto por lo que se refiere a los contenidos como a las plataformas, siempre manteniendo la web en el centro. Teniendo todo esto en cuenta, hemos centrado nuestra estrategia en dos vías principales: la agenda (promoción de los eventos e informaciones prácticas del museo) y la colección, focalizando los esfuerzos en la creación y promoción de contenido relevante centrado en las colecciones del museo.El contenido es clave para conectar con el público y el no público, hacer las colecciones más accesibles, mejorar la experiencia del usuario, extender el conocimiento y trabajar para un museo más social. Por eso hemos apostado por consolidar diferentes proyectos: las exposiciones en línea vinculadas a la programación del museo pero que a la vez ofrecen una experiencia distinta a la presencial; apostando por formatos audiovisuales e inmersivos, como videomappings en grafitos de la pintura mural románica; itinerarios virtuales en súper alta resolución en la app del museo; fotografiado en súper alta resolución y creación de modelos 3D de las obras destacadas de la colección con finalidades educativas y de accesibilidad… En definitiva, enriquecer las colecciones online con nuevas narrativas que optimicen los contenidos digitales que van generando.
Preparation and Corrosion Resistance of an Al2O3/Ni Coating on 316 Stainless Steel in Molten 52MgCl2-48NaCl Chloride Salt
Authors: Wang Changxuan , Zhang Wenjiao , Wang Yanli
Published: October 2022

In this paper, in order to improve the corrosion resistance of 316 stainless steel (316 SS) in molten chloride salt, an in situ grown Al2O3 diffusion barrier is prepared through, first, electrodepositing an inner Ni-Al/NiO composite transition layer and an outer Ni layer through double-pulse composite electroplating technique, followed by annealing at 800°C for 12 h under Ar. The obtained Al2O3/Ni composite coating is dense and shows good adherence to the substrate. Then the corrosion resistance of Al2O3/Ni composite coating in molten 52MgCl2-48NaCl (wt%) is measured through electrochemical technique and immersion tests and the corrosion mechanism is also discussed. The results show that the 316 SS is effectively protected by the Al2O3/Ni composite coating from the corrosion of molten chloride salt.
Ghost of Tsushima Oyununun Greimas’ın Eyleyensel Modeline Göre Çözümlenmesi
Authors: BAKAN Uğur , BAKAN Ufuk , ÜSTÜNDAĞ E. Nilüfer
Published: October 2022

Dijital oyunların başarısı sürükleyici bir öykü ile mekân ve karakterlerin gerçeküstü bir şekilde tasvirleri ile mümkün olmaktadır. Yakın bir geçmişteki popüler oyunların hikâyeleri incelendiği zaman tarihi ve mitolojik olayları konu alan oyunların fazlalığı dikkat çekmektedir. Bu oyunlardan Ghost of Tsushima, 13. yüzyılda Moğol İmparatorluğu’nun doğu seferi sırasında işgal etmek istediği Japonya'ya bağlı Tsushima Adası’ndaki Jin Sakai komutasında halk direnişini konu almaktadır. Bu çalışma, 2020 yılında Sucker Punch Productions tarafından geliştirilen ve Sony Interactive Entertainment tarafından yayınlanan Ghost of Tsushima oyunundaki olay örgüsünün yapısı Greimas’ın Eyleyenler modeline göre incelenmiştir. Oyunun analizi, Greimas (1973) tarafından geleneksel olarak hikâye anlatımındaki farklı rolleri, işlevleri ve eylemleri incelemek ve tanımlamak için geliştirilen nitel bir yaklaşım olan örnekçeye göre yapılmıştır. Bu modelde senaryodaki ilişkilerin, işlevlerin ve olası eylemlerin birbirleriyle olan bağlantıları bir tabloda sunulmaktadır. Araştırma sonucunda oyundaki olay örgüsü edimsel anlatı modelinin temelini oluşturan ve göstergebilimsel kare olarak da bilinen özne, nesne, gönderici, alıcı, destekleyici ve engelleyici öğelere göre tanımlanarak eyleyenler arasındaki ilişkiler ve anlatının işleyiş şeması ortaya konulmuştur.
Bromas y veras en las nuevas medidas de protección por desempleo
Authors: Molina Navarrete Cristóbal
Published: October 2022

La obcecación de la crisis con España, el país que, junto a EE.UU., más sufre el desempleo, obliga a adoptar medidas de todo tipo, tanto de activación del empleo como de protección del desempleado, y tanto para los trabajadores asalariados como para los trabajadores autónomos, tanto individuales como los que llevan a cabo esa actividad a través de formas asociativas –cooperativas y sociedades laborales–. A los primeros dedica el Real Decreto-Ley 10/2009, de 13 de agosto, que introduce, eso sí de forma muy provisional, hasta que se tramite el Proyecto de Ley con el mismo fin arrancado por los Partidos Políticos de Oposición al Gobierno –y al Partido que lo sustenta–, la tan cuestionada ayuda «cheque-parado agotado a partir del 1 de agosto de 2009». A los segundos, destina algunas, muy limitadas, medidas, previstas en el Real Decreto 1300/2009. El estudio que aquí presentamos analiza con detenimiento las claves de uno y otro.
Sucesión de contratos de trabajo de duración determinada: abuso y utilización justificada en el sector público
Authors: Tapia Hermida Antonio
Published: October 2022

La sentencia objeto de comentario aborda un tema de especial actualidad, cual es el de la estabilidad en el empleo, tomando una actitud declaradamente favorable a la contratación indefinida, lo cual es de agradecer en pos de la justicia, la convivencia y la paz social en estos tiempos de tribulaciones y paro masivo, en los que se anatematiza cualquier referencia a que la relación laboral es por su propia naturaleza intrínseca, en cuanto que contrato más cercano a la asociación que a la simple colaboración duradera.
La cuestionable legitimidad de la extinción del contrato de trabajo y de la relación laboral por alcanzar el trabajador la edad de jubilación
Authors: Tapia Hermida Antonio
Published: October 2022

La prohibición de discriminación por edad naturalmente abarca a la relación laboral, de tal manera que aquella no puede, por sí misma, justificar un trato peyorativo para un trabajador. Bajo la eufemística denominación de jubilación convencional, se ha producido un ataque frontal al derecho a la estabilidad en el empleo de los trabajadores a partir de una determinada edad (generalmente la de jubilación establecida en los sistemas de Seguridad Social). La sentencia objeto de comentario reconduce el tratamiento deparado por la jurisprudencia comunitaria a semejante supuesto discriminatorio, y si bien permite nominalmente su pervivencia, las limitaciones y condicionamientos a los que lo somete prácticamente lo proscriben.
