Authors: Rybak Olena , Puskov Dmytro
Published: October 2020

Purpose. The aim of the article is the analysis of the current state of problem debts of Ukrainian banks, research of methods of restructuring problem loans and search for ways to optimize it in a crisis.
Methodology of research. The following methods are used to achieve this goal: dialectical ‒ when clarifying the economic meaning of concepts and terms; analysis, synthesis, sampling, graphic ‒ in the study of the state and structure of problem loans; induction and deduction ‒ to determine the impact of negative factors on the domestic development of lending by commercial banks; comparison ‒ in the study of methods of restructuring problem loans against the background of crisis phenomena and processes.
Findings. Such mechanism as restructuring is considered in the article for minimizing the level of problem loans. It is determined that the implementation of such procedure should take place on a systematic basis, according to uniform rules and apply to all banking institutions.
Taking into account the world experience of problem debt restructuring, the need to improve the legal and regulatory framework for problem debt restructuring in terms of providing tax benefits and the introduction of a balanced procedure for restructuring loans at the state level, providing government guarantees to clients in difficulty with the financial crisis. The necessity of creating an effective mechanism for selling problem assets of commercial banks is substantiated, namely the creation of appropriate asset management companies, companies for repurchase of non-performing loans, etc.
It is proposed to create a separate unit at the level of the banking institution, whose work will focus on choosing the best methods and scenarios for restructuring problem loans and monitoring this process, revealed the need to use automated methods to identify bad debts in banks, which will reduce the number of existing errors, eliminate the human factor and improve the quality of the credit process.
Originality. The necessity of restructuring application by commercial banks of Ukraine against the background of crisis phenomena and processes is substantiated, the influence of restructuring methods on the borrower and the bank is systematized and the ways of improvement of restructuring in the process of working with problem loans are offered.
Practical value. The proposed measures will provide an opportunity to achieve positive dynamics in working with problem loans both at the level of banks and at the state level; will allow to react quickly to unpredictable endogenous and exogenous destructive factors and to minimize risks of their influence on the basic financial and economic indicators of the deposit-taking corporation.
Key words: restructuring, credit, commercial bank, borrower, problem loans, crisis phenomena.

Nanoparticular systems, which have made great advances with the development of nanotechnology, have been used extensively recently in pesticide, herbicide plant growth regulators, fertilizer applications, gene transfer technologies and agriculture. It was aimed to synthesize and characterize 2,4-D loaded PLGA nanoparticles and investigate their biological activity in comparison with its free form. Here, the effects of 2,4-D loaded poly (lactic-co-glycolic) acid (PLGA) nanoparticles on biomass in Medicago sativa cell suspension cultures were investigated. Single emulsion solvent evaporation method is used in nanoparticle synthesis. As a result of the characterization of nanoparticles, 63.82% encapsulation efficiency, 60.73% reaction efficiency and 10.51% drug loading capacities were calculated. Particle size was measured as 181.7 ± 3.74 nm, zeta potential -18.3 ± 1.48 and polydispersity index as 0.081.

Compared with the free 2,4-D molecule, it was observed that the addition of 2,4-D to the medium using the nanoparticles drug release system increased the growth of plant cells and the yield of biomass in M. sativa cell suspension cultures.

One of the major challenges in studying the cosmic evolution of relativistic jets is the identification of the high-redshift (z > 3) BL Lacertae objects (BL Lacs), a class of jetted active galactic nuclei characterized by their quasi-featureless optical spectra. Here we report the identification of the first γ-ray emitting BL Lac, 4FGL J1219.0+3653 (J1219), beyond z = 3, i.e., within the first two billion years of the age of the universe. The optical and near-infrared spectra of J1219 taken from 10.4 m Gran Telescopio Canarias exhibit no emission lines down to an equivalent width of ∼3.5 Å supporting its BL Lac nature. The detection of a strong Lyα break at ∼5570 Å, on the other hand, confirms that J2119 is indeed a high-redshift (z ∼ 3.59) quasar. Based on the prediction of a recent BL Lac evolution model, J1219 is one of the only two such objects expected to be present within the comoving volume at z = 3.5. Future identifications of more z > 3 γ-ray emitting BL Lac sources, therefore, will be crucial to verify the theories of their cosmic evolution.

Authors: Nuralita Nanda Sari , Camellia Vita , Loebis Bahagia
Published: October 2020

BACKGROUND: Schizophrenia is a clinical syndrome that is variable, but highly disturbing; its psychopathology involves cognition, emotion, perception, and other aspects of behavior. Schizophrenic patients who are hospitalized, who return to a family environment characterized by high levels of criticism, excessive emotional involvement, or hostility (referred to as high expressed emotion), are more likely to experience the recurrence than schizophrenic patients returning to families characterized by low expressed emotion.
AIM: We aimed to investigate relationship between caregiver burden and expressed emotion in families of schizophrenic patients.
METHOD: This research is an analytic study with a cross-sectional approach. The research site is in the outpatient installation of BLUD Mental Health Hospital of North Sumatra Province using consecutive sampling non-probability sampling. The samples are family members who carry schizophrenic patients go to an outpatient installation at the BLUD Mental Health Hospital of North Sumatra Province that meets the inclusion and exclusion criteria.
RESULT: The burden of care for the families of the most schizophrenic patients was mid load as many as 36 people, namely 36%, light burden of 34 people, 34%, no burden of 18 people, 18%, and heavy burden of 12 people, 12%. There is a significant relationship between the burden of treatment with expressed emotion, which is 0.004 (p < 0.05).
CONCLUSION: In this study showed a significant relationship between the burden of treatment with expressed emotion (p = 0.004). This study is in accordance with the study conducted by Darwin in 2013, and Carra in 2012, which showed that there was a significant relationship between the burdens of treatment with expressed emotion in the families of schizophrenic patients. Other studies also show that the burden of care has an impact on emotional, physical health, social life, and financial status as a result of caring for sick people.

Published: October 2020

BACKGROUND: AMP-activated protein kinase (AMPK) and PGC-1α were crucial metabolism enzymes not only in the skeletal muscles but also in the liver. Exercise can modify metabolic enzymes to improve insulin resistance.
AIM: The aim of this study was to analyze the expression of mRNA liver metabolic enzymes gene, that is, AMPKα1, AMPKα2, and PGC-1α in different types and intensities of exercise.
METHODS: Healthy male Wistar rats aged 8 weeks in 150–180 g body weight were given a combination of high fat diet for five weeks and low doses of streptozotocin (30 mg/kgbw and 45 mg/kgbw in 0.1 citrate buffer pH 4,5) to develop type 2 diabetes mellitus (T2DM) rat model. Animals then were divided into five groups: One group was sedentary, and four groups were forced to run on the treadmill 3 times/week, 30 min each season, for 8 weeks. mRNA gene expression of AMPKα1, AMPKα2, and PGC-1α was determined with real-time PCR.
RESULTS: The results showed that expression of mRNA AMPKα1 in treatment groups was elevated than control and the much expression was showed in continuous types. The expression of mRNA AMPKα2 and PGC-1 α was declined in treatment group which little expression was showed in high intensity for AMPKα2 and moderate intensity for PGC-1 α. Base on type and exercise intensity, mRNA AMPKα1 gene expression much in moderate continuous, mRNA AMPKα2 gene expression higher in high intensity, both continuous and interval training, whereas mRNA PGC-1α gene expression higher in interval groups.
CONCLUSION: Various types of aerobic exercises with moderate-vigorous intensities gave different impact to mRNA liver metabolic enzyme genes.
Monomorium sahlbergi Emery, 1898 (Formicidae, Hymenoptera): a cryptic globally introduced species
Authors: Boer Peter , Loss Ana Carolina , Bakker Frederique , Beentjes Kevin , Fisher Brian L.
Published: October 2020

The discovery in the Netherlands in a shipping container of the ant Monomorium sahlbergi Emery, 1898, a species similar to the invasive pharaoh ant M. pharaonis (Linnaeus, 1758), led to a quest to better define the distribution of this species, which was initially obscure due to uncertain specimen identifications. Here it is shown that M. sahlbergi, like M. pharaonis, is found worldwide, almost certainly as a result of introductions. Including quarantine interceptions, this species is recorded from seven global biogeographic regions, but its established outdoor distribution is currently limited to the tropics and subtropics. Monomorium dichroum Forel, 1902 is here presented as a junior synonym of M. sahlbergisyn. nov. based on morphometric and CO1 analyses.

Dell Education Services Topic-Based Learning: Using Topic-Based Learning (TBL) to Improve the Learning Experience for our Data Protection Certification eLearning Course
Authors: Cronquist Bruce , Stone Todd
Published: October 2020

Traditional learning is often delivered as larger courses, requiring more development time, and containing substantial amounts of information. Often, that information is not relevant to the learner and, structured in poor sequence, isn't needed until later in the training (if it is even needed at all). Topic based learning, also often referred to as task-based learning, differs from traditional learning because it focuses on what the learner needs to do, versus what they should know. TBL focuses on providing need to know information, closer to the time of need.

This case study shows how using Topic Based Learning, or TBL, improved the learning experience for our Data Protection Certification eLearning course. We’ll also show how it saved not only time for the learners but also time and resources for the Dell Technologies Education Services Department.

Os livros didáticos da perspectiva da sociologia do conhecimento
Authors: Meucci Simone
Published: October 2020

Este artigo propõe uma abordagem dos livros didáticos inspirando-se nos pressupostos da sociologia configuracional e nas questões da sociologia do conhecimento. A abordagem se aplica a pesquisas sobre disciplinas escolares que tomam como unidade empírica um conjunto limitado de livros. Primeiro, apresentamos a definição das operações necessárias à constituição de um campo de conhecimento - identificáveis nos livros didáticos - que denominamos de sistematização, institucionalização e rotinização. Em seguida, identificamos níveis de análise para delinear a configuração da qual os livros são produtos e produtores: articulação entre agências e agentes produtores e consumidores dos livros; processos de formalização de conteúdo; dinâmicas de estabilização e significação do conhecimento. Esperamos, ao final, confirmar o valor heurístico dos livros didáticos para compreender aspectos decisivos da vida intelectual de uma sociedade.
Educação e brasilidade: a política de nacionalização getulista no contexto escolar em Lajeado, Rio Grande do Sul (1939-1943)
Authors: Weizenmann Tiago
Published: October 2020

Durante o Estado Novo (1937-1945), a política de nacionalização tornou-se uma das principais estratégias governamentais para a promoção de uma cultura cívico-patriótica no Brasil, direcionada, sobretudo, às regiões marcadas pela presença de grupos étnicos europeus e seus descendentes, a exemplo dos teuto-brasileiros no Rio Grande do Sul. Assim, o artigo analisa elementos que correspondem aos ímpetos nacionalizadores em uma escola do município de Lajeado/RS, entre 1939 e 1943, valendo-se de fontes documentais como atas, correspondências oficiais e preleções redigidas para horas cívicas, que permitem compreender, no âmbito escolar, traços do imaginário social, relacionados à nacionalidade brasileira.
"El espíritu del pueblo”: estéticas, maestros y folklore en Argentina de 1920s
Authors: Southwell Myriam
Published: October 2020

La década de 1920 fue sumamente rica en lo que respecta a procesos y problemas de singular relevancia y fue además una década prolífica en lo que a debates y generación de nuevas propuestas se refiere. El clima social del la post-guerra ponía en crisis los preceptos más racionalistas que había instalado el liberalismo decimonónico y propiciaba la inclusión de formas de conocimiento ligadas a la espiritual y sensibilidad, más allá de la preeminencia de la razón. Para explorar algunas de las prioridades educativas nos detendremos en el análisis de la Encuesta Nacional de Folklore o Encuesta del Magisterio que se llevó a cabo en 1921 y cuyos resultados fueron reunidos en la ‘Colección de Folklore’. Se trató de una iniciativa en la que se encargó a los maestros de las escuelas nacionales de todo el país la recolección de los elementos folklóricos que encontraran en su jurisdicción: creencias y costumbres, narraciones y refranes, arte y ciencia popular para conocer y prescribir sobre ‘el espíritu del pueblo’
Educação e mundo do trabalho

Published: October 2020

Neste artigo enfocamos as diretrizes e ações educativas da Indústria e Comércio de Minérios S. A. (Icomi), a empresa mineradora que por mais de quatro décadas extraiu e vendeu o manganês de Serra do Navio, no centro do atual Estado do Amapá, no extremo-norte do Brasil. A principal fonte de pesquisa foi a revista mensal da empresa denominada Icomi-Notícias, que durou de 1964 a 1967. Ao relacionar os textos (artigos) e o contexto (abertura de novas frentes de exploração dos recursos naturais amazônicos), foi possível compreender que a educação era pensada e realizada nas company towns da Icomi como uma estratégia de formação de um novo tipo de homem e de sociedade local. A centralidade do trabalho e a especialização profissional eram percebidas como pilares de um novo modo de vida a ser forjado. Para atingir esse objetivo a Icomi construiu duas escolas, dois centros de treinamento, promoveu cursos profissionalizantes, concedeu bolsas de estudos, entre outras ações. Ela também estimulava, por meio de textos publicados na sua revista, o engajamento dos trabalhadores nessa démarche.
Nacionalistas y libertarios
Authors: Ascolani Adrián
Published: October 2020

En el período 1910-1930, la educación nacionalista fue fundamental en el currículo de las escuelas primarias en la Argentina. El Consejo Nacional de educación, organismo dependiente del gobierno federal, estableció la normativa para adaptar a los inmigrantes a la cultura nacional y para contrarrestar la influencia de las teorías colectivistas e internacionalistas en las nuevas generaciones. La ‘historia patria’, con sus símbolos, ceremonias y prácticas escolares cotidianas fue un vehículo fundamental, dando un papel central a los episodios de la independencia política, lograda en 1816. En este artículo se analizan las continuidades y cambios del patriotismo escolar, en su relación con la renovación pedagógica y con la oposición sostenida desde la prensa anarquista, frente al militarismo y al adoctrinamiento de la infancia.

Authors: Mineiro Sergio Luiz , Gonçalo Débora Aparecida Cunha , Okamoto Sayuri , Tenório Plínio Ivo Gama
Published: October 2020

In this work are presented analyzes from calcination and sintering of zinc niobate ceramics by microwave processing. In order to obtain minimum processing parameters, the behavior of the material was first studied for the calcination at different temperatures in the range of 450 to 1150°C, with duration time of 10 minutes. The sintering was carried out between 950 and 1050°C. The results showed that the crystalline structure of the calcined and sintered samples was influenced by the temperature, because, according to the increase in temperature, the evolution of the formed crystalline phases was observed and only the Zn3Nb2O8 and ZnNb2O6 phases prevailed in the final microstructure. The densification of the sintered ceramics was influenced by the time and temperature of the heat treatment, with lower residual porosity and grain growth with the increase of the sintering temperature in the microwave oven.
The Influence of the Microstructure of an HHA Steel on the Formation of Adiabatic Shear Bands, after High Deformation Rates
Authors: de Sant’ana Oliveira Suzane , Weber Ricardo Pondé , Paula Andersan dos Santos , Monteiro Sergio Neves
Published: October 2020

High hardness armor (HHA) steels, when subjected to high deformation rates, are prone to adiabatic shear bands formation. These heterogeneities, formed in a narrow zone, are the result of an intense plastic deformation in which the rate of heat dissipation is low. The generated shear bands can lead to a decrease in ballistic performance and impose to an armor a catastrophic failures. The appearance of these bands may be related to the microstructure or the deformation rate to which the material is subjected. Therefore, this work aims to analyze the influence of the microstructure of an HHA steel, tempered at 310, 425 and 610° C for 2 h, after high deformation rates, in the appearance of adiabatic shear bands. Specimens were dynamic tested in a split Hopkinson pressure bar. It was shown that tempering temperature at 310 ° C for 2h, which produced bainite and martensite with high hardness, was the most susceptible to the adiabatic shear bands appearance.

In this work, it was proposed to study the feasibility of biodiesel production, from residues of vegetable oils used in domestic activities, employing (CaCO3) shells prepared like calcium oxide (CaO) as catalysts, in a batch reaction unit, on bench scale, installed at IPEN-CNEN/SP. This unit is capable of operating with high pressure hydrogen gas (up to 200bar) and high temperature (up to 500°C, using microwave - MW (2.450MHz, with up to 2kW continuous and 8kW pulsed) and conventional heating – (electric) MC. In the tests, the oil load (mL), type and mass of catalyst, with or without hydrogen gas pressure (bar), temperature (°C), reaction time (h), microwave power (W), the speed of the load (rpm) agitation and the conventional heating were evaluated. The analytical determinations of the samples were carried out by means of density, gas chromatography (GC) and X-ray fluorescence. Data were collected in order to be compared with other methodologies, already used in the literature. The purpose of this work was to analyze the efficiency of the use of these types of catalysts and oils in the production of biodiesel, as an alternative technology. The Ca and CaO contents found in the pink shell, before and after the calcination, were 36.2% and 98.8%, respectively. The best result obtained for the density was 0.875182g/cm3, for the test with 4g of calcined shell catalyst and reaction of 1h. As to the methyl ester content, the highest result was 95.33%, in a test with 4g of catalyst and reaction of 3h. In the non-calcined shell test (22.5g), although the amount of mass used was much larger (5% of the oil mass), the ester content was very low, 2.11%.

In order to minimize impacts caused to environment and to save natural resources, especially from non-renewable sources, recycling of polymeric materials has been object of study. In this scenery, are included elastomeric materials, such as rubber, especially used in tires manufacturing, considering that pneumatic industry consumes around 60% of rubber production. Taking into account that final tires destination is a requirement based on norms and national and international laws, this work aims to the development of a study on the efficacy of micro-wave irradiation in the process of de-vulcanization of tire powder to be used in recycling. Tire powder was subjected to micro-wave irradiation and further merged to SBR (butadiene-styrene rubber) polymeric matrix, at 5, 15, 25 phr; after mixture, resulting compound was characterized for evaluation of physico-chemical and mechanical properties. For the assessment of all samples containing SBR and rubber powder there were applied following essays: Infra-red spectroscopy (FTIR), Tensile strength and elongation at break, Swelling Index. It was verified higher values for mechanical properties imparted by an increased quantity of rubber powder incorporated to SBR matrix.

Published: October 2020

This work evaluates the mechanical and dynamic behavior of recycled polycarbonate (rPC) from industrial waste. This study aims to verify whether the recycled process adopted for polycarbonate promotes both mechanical and dynamic properties values under compressive stress, similar to those found for virgin polycarbonate. The mechanical recycling of the rPC was carried out using the thermoforming technique in a thermal press. Two tests were carried out to evaluate the dynamic response of rPC. The quasi-static compression test was performed on a universal machine. The dynamic in a split Hopkinson pressure bar was performed with three different strain rates. The results showed that the mechanical and primary recycling adopted in this work promoted values of yield stress in compression (77 MPa) and dynamic (up to 118 MPa), close to or superior to those reported so far in the literature.

Antiphospholipid antibodies (APAs) are developed antibodies to the phospholipid surfaces or to the proteins binding to phospholipids. Increased PS-expressed red blood cells (RBC) may be a risk factor in APAs development. There were only a few studies reported on APAs in thalassemia, and their associations to PS-expressing microparticles (MPs), remain unknown. The presence of antiphospholipid antibodies (APAs) in pediatric thalassemia patients and their associations with phosphatidylserine (PS)- expressing microparticles (MPs), a previously unexplored relationship, were the aims of this report. We identified that positive APA rates were highest in non-transfusion-dependent thalassemia (NTDT) subjects, followed by transfusion-dependent thalassemia (TDT) subjects and controls (29.5%, 18.2% and 17.9%, respectively).  Subgroup analysis demonstrated that positive anti- ?2 glycoprotein I (a?2-GPI)- IgG rates in NTDT subjects were significantly greater than in controls and that the percentage of MPs was also significantly elevated in thalassemia subjects. More specifically, there were significant correlations found between a?2GPI-IgG and anticardiolipin (aCL)-IgM APAs, and MPs.
PROLIFERATION AND APOPTOSIS OF B-CELL LYMPHOMA CELLS UNDER TARGETED REGULATION OF FOXO3 BY miR-155
Authors: Zheng Xiaoqiang , Rui Hongbing , Liu Ying , Dong Jinfeng
Published: October 2020

This study aimed to explore the proliferation and apoptosis of B-cell lymphoma cells under targeted regulation of FOXO3 by miR-155. We analyzed the differences between B-cell lymphoma cells and B lymphocytes in expressions of miR-155 and FOXO3, explored the effects of miR-155 on proliferation and apoptosis of B-cell lymphoma cells, and relevant mechanisms, and also analyzed the relationship between expressions of miR-155 and FOXO3 in 42 patients with diffuse large B-cell lymphoma (DLBCL) and clinical characteristics of them. B-cell lymphoma cells showed a higher expression of miR-155 and a low expression of FOXO3 than B lymphocytes (both P<0.05). B-cell lymphoma cells transfected with miR-155-inhibitor showed significantly decreased expression of miR-155, significantly weakened cell proliferation ability and increased cell apoptosis rate (all P<0.05), and they also showed up-regulated expression of FOXO3 (P<0.05). Dual luciferase reporter assay revealed that there were targeted binding sites between miR-155 and FOXO3. Compared with B-cell lymphoma cells transfected with miR-155-inhibitor alone, those with co-transfection showed lower expression of FOXO3, higher proliferation and lower cell apoptosis rate (all P<0.05). The expression of miR-155 in DLBCL tissues was higher than that in tumor-adjacent tissues (P<0.05), and the expressions of miR-155 and FOXO3 were closely related to the international prognostic index (IPI) and the 5-year prognosis and survival of the patients (P<0.05). miR-155 can promote the proliferation of B-cell lymphoma cells and suppress apoptosis of them by targeted inhibiting FOXO3, and both over-expression of miR-155 and low expression of FOXO3 are related to poor prognosis of DLBCL patients.

With the introduction of competency-based undergraduate curriculum in India, a paradigm shift in the assessment methods and tools will be the need of the hour. Competencies are complex combinations of various attributes, many of which being not assessable by objective methods. Assessment of affective and communication domains has always been neglected for want of objective methods. Areas like professionalism, ethics, altruism, and communication—so vital for being an Indian Medical Graduate, can be assessed longitudinally applying subjective means only. Though subjectivity has often been questioned as being biased, it has been proven time and again that a subjective assessment in expert hands gives comparable results as that of any objective assessment. By insisting on objectivity, we may compromise the validity of the assessment and deprive the students of enriched subjective feedback and judgement also. This review highlights the importance of subjective assessment in competency-based assessment and ways and means of improving the rigor of subjective assessment, with particular emphasis on the development and use of rubrics.

Viewpoint of COVID-19 in Africa and Latin America
Authors: HERBERT Ernest , FOURNİER Dominique
Published: October 2020

The spread of COVID-19 across the African continent and Latin American region is of great concern due to several influencing factors. Large and densely populated areas and townships with widespread poverty and high migration are the most vulnerable populations for a pandemic of this magnitude. The latter could be complicated since known communicable diseases such as chronic obstructive pulmonary disease (COPD), diabetes, cardiovascular disorder, hypertension and lack of basic healthcare delivery systems are known risks that may enhance the degree of mortality, via the pandemic in affected regions. The aim of this review is to focus on the clinical signs, transmission, case fatalities and influencing factors that might exacerbate the pandemic in these regions.
Acute aortic dissection case with stroke presentation.

Published: October 2020

The correct diagnosis of acute aortic syndrome complicated by neurologic symptoms is essential. Performing thrombolytic therapy for acute-stage cerebral infarction would probably be the reason for fatal outcomes. We herein report the case of a 63-year-old man who presented with left hemiparesis and paraparesis. An acute myocardial infarction was excluded by electrocardiography and blood tests. Head computed tomography (CT) showed no remarkable findings. Although there was no chest pain, it was found in CT-angiography that he has an intramural hematoma in the ascending aorta and a severe dissection in the descending aorta. Aortic dissection may mimic acute stroke, in order to make the right decision about the treatment of acute aortic syndrome with neurologic complications, the benefits and risks should therefore be considered in individual patients.

Objective: Kidney transplantation is one of the most important treatments in end-stage renal disease (ESRD). We aimed to share our experiences in 60 (57 deceased donors, 3 living donors) kidney transplantation cases performed in our center between July 2017 and August 2020. Material and methods: The demographic data of 60 patients with kidney transplantation performed in our kidney transplant center were evaluated in terms of causes and duration of renal failure human leucocyte antigen (HLA) tissue compatibility, immunosuppressive protocol used, antimicrobial agents, rejection status, graft loss, patient loss, postoperative surgical complications. Results: 57 of our kidney transplants were made from deceased donors and 3 from living donors. The mean age of the patients was 44.66 (23-68) years. Kidney transplantation was performed in 8 patients (13.33%) in the preemptive period. The mean number of mismatches in kidney transplants was 3.95 (2-5) and the mean duration of renal replacement therapy (RRT) was 54.73 (0-270) months. While the mean follow-up period after transplantation was 18.86 (2-37) months, it was observed that the mean cold ischemia time was 742.8 (60-1080) minutes. Serum creatinine levels of 56 patients with functional grafts at the end of the first month 1.39 (0.5-4.9) mg/dL, 54 patients at the end of the sixth month, creatinine levels 1.29 (0.56-5.9) mg/dL, The creatinine levels of the 52 patients as of October 2020 were 1.37 (0.75-5.16) mg/dL. As surgical complications, hematoma developed in 5 patients (8.33%) and lymphocele in 3 patients (5%). Early graft loss developed in one patient with renal artery embolism and two patients with renal vein thrombosis, while chronic rejection developed in two patients. We performed a deceased kidney transplant again 14 months later in a patient who developed graft loss in the early period due to renal vein thrombosis. The kidney inserted later is functional in the 10th postoperative month. One of our patients died due to rhino-orbital mucor mycosis in the postoperative 2nd month, and one patient due to the development of sepsis due to infection in the hip prosthesis in the postoperative 6th month, while another patient died due to myocardial infarction in the postoperative 2nd month. Conclusion: As a result, our kidney transplant center is in development. Our results obtained from 60 kidney transplants, almost all of which were performed from deceased donors, seem to be compatible with the literature. More detailed results can be obtained with the long-term follow-up results and the increase in the number of living donor transplants.

Published: October 2020

The purpose of this paper is to analyze the causes of delay in the work response of the actuator in controlling the action on the fuel injection pump rack when the ship is sailing. An actuator is a propulsion device that is driven by a pneumatic system (compressed air system) or a hydraulic system (hydraulic oil media) in the world of control applied as a safety device for machines. The accuracy of the actuator process as a tool used in security equipment on the ship's main engine plays a very important role in keeping the main propulsion engine working in safe conditions. Against the background of the weak work response of the actuator as a fuel rack propulsion on the fuel injection pump which results in damage to the main engine due to Overspeed. The problem that will be analyzed is the number of things that make the actuator work incompatible with its function. In its use, the actuator gets a signal command from the tachometer which functions to read the engine speed, which was previously sent to the Safety System Unit (SSU) to be processed and compared with the desired value/set according to the standard manual book of the machine. The method used is to use a qualitative descriptive approach. The conclusion of this paper is the need for good maintenance in the actuator system to prevent it from failing to protect engine work, such as checking the work response in pushing, pneumatic, or hydraulic drive systems, calibrating the output value of the tachometer or the system from the Safety System Unit (SSU).
