Published: November 2020

The burden of end of life in Internal Medicine wards is not neglegible. However, literature evidence about end of life care in Internal Medicine wards lacks. Therefore, the aim of this study was to report on end of life management in a Internal Medicine ward. We performed a retrospective study focusing on characteristics and management of patients consecutively died in an italian Internal Medicine ward between 2018, July-1 and 2019, June-30. Demographic, co-morbidity, pharmacological treatment at hospital admission and in the last 48- hours of life and procedures during hospital stay were collected. Study population was composed by 354 patients (190 females), corresponding to about ten percent of patients admitted in the ward, with mean age ± DS 83.5 ± 10.6 years. Eighty-four percent of deaths was exepected in the last 48 hours before exitus. The main co-morbidities were blood hypertension (66.3 %), solid or haematological malignancies (40.3%), arhythmias (34.7%), pressure ulcers (31.3%) and diabetes (27.4%). The main causes of hospitalization were infectious diseases (23.1%) and cardiac or respiratory failure (20.9%). In seven percent of patients palliative cares had been already activated before the hospital admission. No patient had written living wills or advance directives. In the last 48 hours of life, the main phramacological classes prescribed were opioids (63.2%), antibiotics (46.9%) and corticosteroids (46.3%). Compared with pharmacological classes prescribed at hospital admission, in the last 48 hours of life the prescription of antibiotics, corticosteroids, opioids and benzodiazepines was significantly increased, whereas the prescription of antihypertensive agents, proton pump inhibitors and antithrombotic drugs resulted significantly reduced. Written order to withdrawal of vital parameters relevation or active treatment were found in 30.7% and 31.9%, respectively. In the last 48 hours of life, 61% of patients underwent to at least one blood assay, 34% arterial blood gas analysis and about 35% at least one of radiography, computer tomography, magnetic resonance or endoscopy. During hospital stay 9% of patients underwent to blood transfusion. Of them 28.1% of patients received blood transfusion in the last 48 hours of life. Appropriate management of end of life represents a challenge in Internal Medicine wards.

Physical and chemical characteristics of 1300 lakes and ponds across the Canadian Arctic
Authors: Liang Tanner , Aherne Julian
Published: November 2020

Lakes and ponds are a major feature of the Arctic landscape and are recognized as effective ‘sentinels of change’. Here we present water chemistry characteristics of lakes and ponds (n=1300 with 26 variables) across the Canadian Arctic collated from published studies. We also extracted geological and ecoregion data in an attempt to determine the key drivers. In general, most lakes were shallow (85.4%, <10 m), nutrient (phosphorus) poor (oligotrophic = 45.6% and ultra-oligotrophic = 24.8%), located at low elevation (66.5%, <200 m asl), close to coastlines (72.5%, 0-50 km), and underlain by sedimentary geology (66.5%). The first two components from Principal Component Analysis explained 49.3% of the variation in the dataset; the first component was dominated by conductivity/carbonate materials, and the second component suggested allochthonous inputs of phosphorus. In general, bedrock geology is the primary driver of water chemistry; as such, there were major differences between lakes underlain by igneous and sedimentary rocks. Those on sedimentary bedrock tend to have higher pH, nutrients and higher inorganic ion concentrations.
L’essenziale nelle professioni sanitarie: riflessioni di un clinico
Authors: Lombardi Domenico
Published: November 2020

Nell’articolo vengono riportate alcune riflessioni sui principi di riferimento ed i comportamenti nelle professioni sanitarie. L’Autore ritiene che i mezzi idonei per qualificare il servizio al paziente e mantenere un alto livello di professionalità degli operatori siano tanto gli strumenti tecnico-scientifici quanto quelli etico-culturali, proprio al fine di una migliore soddisfazione della domanda di salute.

Si discute inoltre sulle finalità della professione sanitaria e sulla qualità della vita, quest’ultima intimamente connessa al concetto di salute. Nella professionalità sanitaria sono distinte quattro parti: fisica, psichica, conoscitiva e volitiva e si indicano alcuni riferimenti per migliorarla. Riguardo poi all’atto professionale, questo è da considerare adeguato laddove libero e responsabile, ed ancora l’approccio olistico al malato è ritenuto il più proficuo, anche per lo specialista.

Si tratta, poi, dello sviluppo della medicina specialistica e dell’attuale validità delle “discipline madri” (medicina interna e chirurgia generale) individuandosi altresì i requisiti che qualificano sia le strutture sanitarie sia la condotta degli operatori sanitari.

Per l’aspetto sociale della medicina si accenna ai principi che dovrebbero regolare la sanità, in cui la salute non deve mai diventare merce di scambio. Infine si ribadisce l’essenzialità del rapporto fiduciario tra paziente ed operatore sanitario; in esso andrebbero privilegiati, oltre che la competenza del curante, anche la conoscenza umana ed il rispetto del malato nella sua ontologica unità somatica, psichica e spirituale. Sono riportati peraltro alcuni riferimenti legali ed etico-deontologici che dovrebbero guidare i comportamenti degli operatori sanitari.
Storia della normativa italiana in materia di medicinali fino alle norme più recenti sulla valutazione bioetica della sperimentazione clinica
Authors: Scuderi Gabriella
Published: November 2020

Dopo un breve excursus storico dei provvedimenti normativi sui medicinali adottati nella Unione Europea e recepiti dall’Italia, vengono descritti gli sviluppi più recenti della normativa sulla valutazione bioetica della sperimentazione clinica (ossia della fase di sperimentazione del farmaco sui soggetti umani che succede alla fase di sperimentazione sull’animale). In particolare, l’Autrice prende in esame le Nuove Norme Europee di Good Clinical Practice (GCP) e le ricadute che hanno portato alla normativa emanata in Italia riguardo il “consenso informato” ed il ruolo dei Comitati Etici. Inoltre, sono illustrati gli ultimi provvedimenti della normativa italiana. Questo lavoro costituisce dunque una rassegna sull’argomento. Certamente, allo stato attuale in Italia sono stati realizzati molti progressi nella trasposizione della legislazione comunitaria in diritto nazionale soprattutto nel campo della sperimentazione sui soggetti umani in particolare ma, probabilmente, altro lavoro deve essere svolto per coprire più vaste necessità in molti altri campi della ricerca scientifica in generale.
Dimensioni culturali e tematiche del movimento pro-eutanasia: il caso particolare dell’Olanda
Authors: Schepens Philippe
Published: November 2020

L’articolo si occupa dell’eutanasia e particolarmente di questo tema nel contesto olandese, interrogandosi anzitutto sulle cause che indurrebbero il popolo olandese e in particolare i medici di quella nazione ad un atteggiamento maggiormente favorevole rispetto ad altre popolazioni europee o occidentali. Ad avviso dell’autore, la motivazioni è duplice: socio-culturale e filosofica.

Per un verso, sussiste in Olanda una cultura tesa tra la tolleranza e l’orgoglio della propria autosufficienza, che catalizza un’accelerazione dell’accettazione dell’eutanasia. D’altro canto, in quella nazione si risente come altrove del pensiero umanista secolarizzato, il cosiddetto “libero pensiero”, teso fra intellettualismo ed ateismo. Secondo tale orientamento, il bene essenziale per l’uomo è la sua salute. In tal modo, lo stesso medico è indotto ad abbandonare il classico ruolo ippocratico di essere al fianco del paziente per curarlo, per alleviarlo qualora sia impossibile la cura, e consolarlo se non può sollevarlo. Oggi, il medico rischia di diventare un esperto che giudica della vita e della morte, una sorta di sommo sacerdote della salute.

L’articolo, poi, si diffonde dettagliatamente sulla situazione legale ed epidemiologica olandese, concludendosi con una presa di posizione contraria all’eutanasia, sostenendo che quando il fondamentale diritto alla vita è negato a qualsiasi individuo umano, di fatto si abbandona la democrazia per entrare in una nuova era totalitaria.
Dimensioni culturali e tematiche dei movimenti pro-eutanasia: la situazione fuori dai Paesi Bassi
Authors: Herranz Gonzalo
Published: November 2020

Sorge all’interno del dibattito teologico, da parte di chi maggiormente ha sentito l’influsso del cosiddetto (ma solo cosiddetto…) “cattolicesimo liberale” e soprattutto nell’ambito medico, in cui la linea di pensiero liberista e utilitarista ha un ampio spazio, la riflessione sulla “libertà del morire”. A nostro parere siamo di fronte ad un’inopportuna e falsificata accezione del termine libertà, che viene ad essere invocata per costruire e fondare un altrettanto falso “diritto a morire”. Si tratta di una concezione di libertà non autenticamente tale: il “diritto a morire” secondo noi non può esistere, perché si tratterebbe di una contraddizione in terminis, che va a minacciare il diritto ben più accertato e riconosciuto che è quello “a vivere”: esiste se mai un diritto a vivere qualitativamente bene, e non solo dal punto di vista biologico, ma soprattutto antropologico, anche l’atto supremo della vita umana naturale che è appunto il morire, inteso a tutti gli effetti come atto della vita. Anche la volontà del paziente (living-will) non è il termine ultimo della sua libertà, la quale ha da confrontarsi con altre volontà, come del resto accade in tutte le azioni umane.

Saranno poi necessarie delle specificazioni, caso per caso, o per gruppo di casi, atte ad evitare le possibili forme di accanimento terapeutico, laddove si sostituisca un “vitalismo biologico”, il più delle volte artificiale e attuato con mezzi sproporzionati, alla vita propriamente intesa.

Cryptococcal empyema treated with tube thoracostomy and intrapleural fibrinolysis
Authors: Kohli Akshay , Sachdeva Ashutosh , Pickering Edward M.
Published: November 2020

A 55-year old woman with a history of relapsed T-cell ALL presented with right pleuritic chest pain and decreased breath sounds over the right hemithorax. Imaging of the chest showed loculated effusions. Tube thoracostomy was performed with intrapleural application of alteplase and dornase alpha over a 3-day period. Repeat imaging demonstrated a marked decrease in the volume of the effusion. In most prior published cases of pleural cryptococcosis, surgical drainage was required in addition to prolonged antifungal agents. More than 50% of patients with cryptococcal infection have severe underlying disease or immunodeficiency state making them high risk for surgery. This is the first case to our knowledge of cryptococcal empyema successfully treated with tube thoracostomy and intrapleural fibrinolysis.
Incorporating Retrieval Practice Into Intensive Care Unit Teaching Rounds: A Feasibility Study
Authors: Cooper Avraham Z. , Verbeck Nicole , McCallister Jennifer W. , Spitzer Carleen R.
Published: November 2020

Background

Teaching rounds are an important component of the learning environment for residents in the intensive care unit (ICU). Retrieval practice is a cognitive learning tool that helps learners consolidate information and might improve the quality and culture of teaching rounds.

Objective

We performed a feasibility study from October 2018 to June 2019 to investigate the incorporation of retrieval practice into ICU rounds.

Methods

Participants included internal medicine and family medicine residents and pulmonary and critical care medicine fellows and faculty on medical ICU (MICU) teams at a tertiary care academic medical center. For 1-week periods, residents were asked to use retrieval practice after rounds, sharing one learning point. Participants were anonymously surveyed about the feasibility and acceptability of this strategy and perceptions of the educational value of ICU rounds before and after incorporating retrieval practice.

Results

We enrolled 9 MICU teams, including 31 residents, 8 fellows, and 8 attendings. Pre- and postsurvey response rates were 89% and 91% (42 and 43 of 47, respectively). Sixty-nine percent of respondents (30 of 43) reported sharing learning points on at least 3 days of the intervention week. Eighty-six percent of respondents (37 of 43) said retrieval practice did not adversely affect the workflow at the end of rounds. The perception that teaching on rounds was a priority increased after the intervention (3.93 versus 4.28 on 1–5 Likert scale, P = .047).

Conclusions

Using retrieval practice on MICU rounds was feasible and acceptable and was associated with an increase in the perceived priority given to teaching on rounds.
PREOPTEREĆENOST UČENIKA ŠKOLSKIM OBAVEZAMA / STUDENTS OVERLOAD WITH SCHOOL DUTIES
Authors: Zvizdić Sibela , Dautbegović Amela
Published: November 2020

School in the modern society should provide an environment for students to feel safe and motivated for learning. There should be an optimal student workload with the schoolwork as well as with the homework. Unfortunately, student overload at all levels of education has been evident. Their overloaded schedule presents a significant challenge and may cause fatigue, exhaustion, distraction, mope, high levels of stress, apathy, superficially and campaign learning, and general lack of motivation. Due to the topicality of the issue, the authors of this paper have tried to offer a review of the sources of the student overload. Different sources, as well as negative consequences of student overload have been determined based on a significant number of empirical works so far. The article also suggests measures to relieve students. Psychologists, in cooperation with the students’ parents and experts from other branches of the education sector, can contribute in finding a way to prevent and reduce consequences of the overload. Empirical studies about sources of student overload are also necessary to determine evidence based guidelines for the education reform.
PROMJENA ZATVORSKE PARADIGME? / THE CHANGE OF THE PRISON PARADIGM
Authors: Kasumović Amila
Published: November 2020

The reform of the legal system that the Ottoman Empire conducted in the 1850s was systematically implemented in the period that followed, with an attempt to introduce new legal provisions concerning prisons in all parts of the Empire, including Bosnia. Displeasure of the western powers who had insisted on changes to the prison practices in the Ottoman Empire, the pace of which had been slow, was used by the Austro-Hungarian Monarchy following the occupation of Bosnia and Herzegovina. Having established that the existing conditions in BiH prisons were “miserable”, the new government promised radical changes. However, the question is if the changes really were ferocious in the decisive years in which the Ottoman administration was replaced by Austro-Hungarian? If so, to what extent was the prison paradigm changed? A more serious investigation of the prison system of a certain administration demands an analysis of a specific group within the prison population. One such group are women that needed a different treatment compared to other prisoners: a separate accommodation, female, not male, supervision, as well as special measures during pregnancy, delivery and breastfeeding. By using the documents from ZVS and ZMF funds, the paper aims to investigate if the Austro-Hungarian administration managed to achieve significant results in the treatment of female inmates in Bosnia and Herzegovina in the first years of the monarchy’s rule. Although the prison system and the treatment of prisoners are an important indicator of the civilizational advancement of a society, the local historiography has not paid significant attention to these issues. This paper is trying to fill that void.
MAPPING THE METAFICTIONAL / MAPIRANJE METAFIKCIJE
Authors: Stojanovic Aleksandra
Published: November 2020

The aim of the paper is to present Aleksandar Hemon’s The Lazarus Project as a postmodern narrative which employs various strategies such as an altered view of history, namely history serving purely as material to construct a new narrative, a growing emphasis on the manner in which space affects one’s identity and overall hybridity in both the narrative structure and the characters themselves. We shall discuss Linda Hutcheon’s notion of historiographic metafiction as the key concept around which the narrative is formed, followed by a view of the characters’ search for identity in the metafictional labyrinth through Fredric Jameson’s concept of cognitive mapping. These two theories combined give us a more detailed look into the narrative structure of the novel and provide evidence of its postmodernity. The aforementioned hybridity will be presented in the context of the narrative structure resembling a loop due to its metafictional nature and through the amalgam of various nationalities in each character. The paper ultimately strives to express the postmodern characteristics of the narrative and draw attention to the way the themes of the literary work are emphasized by such a structure, more so than if any other narrative structure had been used.

SUSRET HEIDEGGERA I WITTGENSTEINA / THE ENCOUNTER OF HEIDEGGER AND WITTGENSTEIN
Authors: Olovčić Adem
Published: November 2020

This paper focuses on language as a medium for a critique of the traditional metaphysical concepts, expressed in the philosophies of two contemporary philosophers, Martin Heidegger and Ludwig Wittgenstein, where the language is treated as a framework for understanding the world in a multitude of its, for philosophy significant determinants. Although Heidegger, in his philosophy, was primarily concerned about the question of the being, he seeks that sense in thought, which took him away to language, as the only place where the given questions can be examined. Considering that the truth of the being cannot be expressed in everyday, linguistically and instrumentally conceived language, Heidegger will in his thought reach the language of poetry, as place were the understanding of the truth of being and its related concepts is possible. Wittgenstein, on the other hand, will focus in philosophical thought on the problems of language, which, in his philosophy, will culminate in the notion of a language game. With this term, Wittgenstein, first of all had in mind the interconnectedness of the use of language and the life practice. Still, he did not think of a language as an everyday – practical instrument of communication, but rather, as a place where linguistic definitions of language, everyday life practices and real life events meet.  In doing so, these thinkers, through their interpretations of linguistic issues, have reached a point in which is possible to understand their encounter.

Ekspertni sistemi u sprintu
Authors: Pelemis Vladan , Pavlovic Slobodan , Solaja Anita
Published: November 2020

Cilj rada je da se prikažu i jasnije definišu eks­pertni sistemi u sprintu, tj. načini kontrole i ocenjivanje sprinta kao i evaluacija postignutih rezultata, kod dece selektovane za atletiku škol­skog uzrasta. U atletici još nije modelovan ni jedan ekspertni sistem koji bi omogućio trenerima sistematsko praćenje rezultata sportista različi­tog uzrasta, kao i predikciju njihovih rezultata u budućnosti. Brz razvoj tehno­logije omogućava nam dobijanje sve većeg broja objektivnih podataka na osnovu kojih možemo da dobijemo vernu sliku tehnike kretanja. Moramo ipak, naglasiti, da je većina metoda za ocenu tehnike atletskih disci­plina dosta komplikovana, zahteva posebne aparature i posebno obučen kadar. Predloženi kriterijumi za kontrolu i ocenu sprinta predstavljaju sponu između naučnih istraživanja i prakse. Implementacija izloženih kriteri­juma je primenjiva kako u školsko obrazovnom sistemu, kao kolevci mladih talenata, tako i u sportskim klubovima, kao kolevci svetskih rekordera.

\mathcal{I}- almost Lacunary vector valued sequence spaces in 2- normed spaces
Authors: SAVAS Rabia
Published: November 2020

One of the wide-ranging applications and research areas of Summability theory is the concept of statistical convergence. This concept was studied a related concept of convergence by using lacunary sequence by Fridy and Orhan. At the last quarter of the 20th century, lacunary statistical convergence has been discussed and captured significant aspect of creating the basis of several investigations conducted in many branches of mathematics. On the other hand, in 1961 Krasnoselskii and Rutisky presented the definition of Orlicz function. Also, in 1963 G\"{a}hler introduced the notion of 2-normed spaces. The main goal of this article is to introduce $\mathcal{I}-$ almost convergence of lacunary sequences with regard to an Orlicz function
in 2-normed spaces and other sequence spaces by considering the concept of
ideal that was presented by Kostyrko and others. Additionally, we examine the relationship between these sequence spaces and fundamental inclusion theorems are investigated.
Intellectual technology for computation control in the package of applied microservices
Authors: Bychkov I.V. , Oparin G.A. , Bogdanova V.G. , Pashinin A.A.
Published: November 2020

The complexity of exhaustive problems with the properties of large-scale, openness, unpredictable dynamics, and component mobility determines the relevance of developing microservice-oriented software for their solving in a hybrid computational environment. We propose an approach for adapting to this environment both the existing software and new ones developed using new automated technology for creating an applied microservice package and organizing control of computations in it. The distributed computational model is represented by a set of small, loosely coupled, replaceable, interacting with the use of lightweight communication mechanisms autonomous microservices that implement the functions of the program package modules. The decentralized management of the microservices interaction is carried out by a self-organizing multi-agent system, agents of which are delegated the rights to launch microservices. The paper discusses the models, methods, and software platform that form the basis of the proposed technology. We demonstrate the application of the applied microservice package, based on this technology, for solving the problems of qualitative analysis of binary dynamic system using the author's Boolean constraints method.
Framework for preparing subject data in testing modules of scientific applications
Authors: Fereferov E.S. , Feoktistov A.G. , Bychkov I.V.
Published: November 2020

The paper addresses the relevant problem of data preparation for testing modules of scientific applications. Such testing requires the multiple executions of modules with different parameters for various scenarios of solving problems in applications. Often, data sources for parameters used for problem-solving are subject data (experimental results, reports, statistical forms and other information resources) created earlier as a result of functioning various objects of a subject domain. Usually, such data are heterogeneous and weakly structured. The developer of scientific applications has to make additional efforts in extracting, cleaning, integrating, and formatting data in order to achieve the correctness and efficiency of their use in applications. The aim of the study is the development of a framework for automating the description of semi-structured data and their transformation into target structures used by scientific applications. We proposed a conceptual model that allows us to represent knowledge about the structure of the source data, determine their relations with the target structures and set the rules for data transformation. Additionally, we developed a framework prototype. It is integrated into the technological scheme of continuous integration for modules of scientific applications (distributed applied software packages) that are developed with the help of Orlando Tools. The effectiveness of this prototype functioning is confirmed by the results of experimental analysis.
Meta-monitoring system for ensuring a fault tolerance of the intelligent high-performance computing environment
Authors: Sidorov I.A. , Sidorova T.V. , Kurzibova Ya.V.
Published: November 2020

The high-performance computing systems include a large number of hardware and software components that can cause failures. Nowadays, the well-known approaches to monitoring and ensuring the fault tolerance of the high-performance computing systems do not allow to fully implement its integrated solution. The aim of this paper is to develop methods and tools for identifying abnormal situations during large-scale computational experiments in high-performance computing environments, localizing these malfunctions, automatically troubleshooting if this is possible, and automatically reconfiguring the computing environment otherwise. The proposed approach is based on the idea of integrating monitoring systems, used in different nodes of the environment, into a unified meta-monitoring system. The use of the proposed approach minimizes the time to perform diagnostics and troubleshooting through the use of parallel operations. It also improves the resiliency of the computing environment processes by preventive measures to diagnose and troubleshoot of failures. These advantages lead to increasing the reliability and efficiency of the environment functioning. The novelty of the proposed approach is underlined by the following elements: mechanisms of the decentralized collection, storage, and processing of monitoring data; a new technique of decision-making in reconfiguring the environment; the supporting the provision of fault tolerance and reliability not only for software and hardware, but also for environment management systems.
Estudo da influência do teor de fibras e de compatibilizante na obtenção de compósitos de polietileno de alta densidade pós-consumo (PEADpc) com fibras de bagaço de cana-de-açúcar (BCA)
Authors: Dias Gomes Líbano Elaine Vidal , Da Costa Pereira Patrícia Soares , Bastos Daniele Cruz , De Souza Coelho Karolina Vieira
Published: November 2020

A produção de novos materiais com reutilização de resíduos é uma tendência do mercado que visa ao mesmo tempo obter produtos ecologicamente corretos, reduzir o custo de produção, diminuir o desperdício, valorizar a matéria-prima e principalmente buscar a reutilização desses materiais. O polietileno de alta densidade (PEAD) é um dos principais resíduos sólidos gerados pelo homem, sendo facilmente encontrado nos aterros sanitários brasileiros. O Brasil é um grande produtor de cana-de-açúcar e gera milhares de toneladas de resíduos lignocelulósicos de bagaço de cana-de-açúcar (BCA). O PEAD e o bagaço podem ser reaproveitados na produção de materiais compósitos junto com os agentes compatibilizantes que agem na interface, proporcionando uma adesão mais adequada. Neste trabalho foram preparados compósitos de PEAD pós-consumo (PEADpc), BCA (10, 20 e 30% em peso) na ausência e presença de agente compatibilizante (3 e 5% em peso) em extrusora dupla-rosca. Os corpos de prova foram obtidos por compressão e caracterizados por ensaios físico-mecânicos, estruturais e térmicos. Os compósitos apresentaram diminuição da dureza e do índice de fluidez independente do teor de fibras e da presença do compatibilizante. Não houve mudança significativa nos valores de densidade.  Os resultados mostraram que a quantidade de fibras não exerceu muita influência na quantidade de água absorvida dentro de um mesmo intervalo de tempo. Os resultados de difratometria de raios X revelaram um discreto deslocamento do pico para ângulos menores e com menor intensidade. Na calorimetria diferencial de varredura não foram observadas alterações na Tm e Tc dos compósitos, enquanto a análise termogravimétrica mostrou uma redução na estabilidade térmica dos compósitos.

Todas as partes foram pesquisadas a partir de levantamento bibliográfico.
Caracterização termoanalítica do sulfato de cobre pentahidratado
Authors: Carneiro da Silva Lucas Rafael , Pinto Railson Machado
Published: November 2020

A análise térmica é o conjunto de técnicas, no qual, uma propriedade física é medida durante um período de tempo em que a amostra é sujeitada a um programa controlado de temperatura. O presente trabalho a partir de técnicas termoanalíticas, como a TG, DTG, DSC e DTA, avaliou a estabilidade térmica do Sulfato de Cobre Pentahidratado (CuSO4.5H2O). O estudo de termodecomposição do CuSO4.5H2O foi conduzido sob atmosfera dinâmica de Argônio (Ar) com o fluxo de 50 ml/min, da temperatura ambiente até 1000 °C e com razão de aquecimento de 10 °C/min. Com base nos resultados obtidos, pode-se concluir para a análise por TG e DTG que a termodecomposição do CuSO4.5H2O ocorreu em seis eventos térmicos, cada um relacionado à saída de uma molécula e indicado por uma perda de massa. Todos os picos da análise por DSC e DTA tiveram o caráter endotérmico. As técnicas se mostraram satisfatórias na caracterização térmica do material.
Dyskeratosis congenita: a case report on a rare disease

Published: November 2020

Abstract

Dyskeratosis congenita is a very rare inherited haematological disorder characterised by a classical clinical triad of leukoplakia, skin pigmentation and dystrophied nails. Here is a case of a young patient who presented with brittle nails, lacy hyperpigmentation of the skin and leukoplakia along with pancytopenia. Haematopoietic stem cell transplantation is the only cure for this disease but due to financial constraints of the family it was not possible. The patient was placed on androgen therapy and showed favourable response but later was lost to follow-up.

Patient’s expectations of privacy and confidentiality in Pakistan: a mixed-methods study
Authors: Bushra Shirazi  , Sualeha Shekhani
Published: November 2020

Abstract

Privacy and confidentiality are considered a cornerstone in the practice of medical ethics. However, these notions may play out differently in the cultural context of Pakistan. In order to understand the perceptions and expectations of privacy and confidentiality, a cross-sectional mixed method study was undertaken in a tertiary care hospital in Karachi, Pakistan. While the subjects demonstrated unfamiliarity with the Western terms, majority of them also exhibited a high expectation for privacy (both informational and physical) and confidentiality. Patients appeared most comfortable with sharing private medical information with the primary physician, indicating the level of trust placed in the physician. Participants also showed high expectations for confidentiality, thus, even in a collectivist society, patients may not want their private information shared across the medical team and also among family members. The onus is, therefore, on healthcare professionals to assess patients’ preferences and choices.

The economic life of the community has increased welfare through the empowerment of their customs. In the first year (2019) conducted research on indigenous peoples in 3 provinces: Bali which succeeded in developing the Village Credit Institution (LPD), the Batak indigenous people in North Sumatra succeeded in developing CU Ate Keleng, and the indigenous Dayak people in Central Kalimantan succeeded in developing CU Betang Asi. In the 2nd year (2020) conducted research on the indigenous peoples of 3 provinces: Betawi in DKI Jakarta which succeeded in developing the service cooperative "Jakarta Tentram Sejahtera", the Sundanese indigenous people in West Java succeeded in developing the North Bandung Cattle Breeders Cooperative (KPSBU) Lembang and Social Entrepreneurship The Big Price Cut Group, and the Acehnese indigenous people in Aceh have succeeded in developing the economy with the Baitulmal concept. With this business sector, it can empower indigenous peoples and at the same time improve the economy and welfare of their people. The empowerment of indigenous peoples is based on the concept that every member of the community has an obligation to support their respective customary activities. The customary institutions or types of businesses that exist in each location of this research aim to make it easy for the community to get capital in developing their respective businesses and in selling their products. With the existence of this financial institution, indigenous people experience an increase in their economy and welfare. To achieve this goal maximally and to find a model of economic empowerment for indigenous peoples that can be used as a model for the economy throughout Indonesia, in the 3rd year (2021) research will be continued in the Provinces of Maluku, West Sumatra, and South Sulawesi. In general, this research aims to produce an economic model for indigenous peoples as a strategy to accelerate national economic development. Specific objectives: To find out how indigenous peoples develop their economic systems; to identify forms of economic institutions for indigenous peoples in Indonesia, and to formulate a model for the economic empowerment of indigenous peoples as a strategy for accelerating national economic development. Researchers used qualitative and quantitative descriptive methods (mixed method) with a comparative case study type. Thus, this research is expected to obtain a model in order to accelerate national economic development. Data were collected and analyzed by means of observations, interviews, and documents. The mandatory output of this research is the economic model of indigenous peoples.

Authors: Pomareda Angulo Elena
Published: November 2020

El trabajo corresponde a una investigación básica, de naturaleza descriptiva correlacional debido a que está basado en especificar propiedades, características y determinar la relación de las variables de estudio: restricciones internas y competitividad de las MYPES del Sector Confecciones. Para tal propósito se consideró la información obtenida a través de la aplicación del cuestionario a 100 empresarios de las micro y pequeñas empresas del distrito de Tacna a fin de conocer las restricciones internas y la competitividad de las mismas.

El objetivo fue determinar de qué manera inciden las restricciones internas en la competitividad de las MYPES del sector confecciones textiles, del distrito de Tacna, en el periodo 2007- 2008.

Los resultados más importantes son las restricciones internas que inciden en la competitividad de las MYPES del sector confecciones textiles (las limitadas capacidades gerenciales, las escasas capacidades operativas y el bajo nivel de tecnología) evidenciándose sus limitadas capacidades empresariales. Los directivos, en su mayoría, han sido formados empíricamente; no desarrollan habilidades gerenciales para la mejor solución de la problemática existente; tales como: dirigir un equipo de trabajo, enfrentar situaciones difíciles de disciplina y de intereses que pudieran surgir en el grupo, logro de resultados.

Las MYPES se caracterizan por su bajo nivel de competitividad, debido a su bajo nivel de productividad; puesto que los empresarios no han hecho eficiente uso de los recursos (insumos) al producir sus productos.
Modelo recursivo de gestión holística de activos y pasivos (GHAP) para optimizar los resultados económico financieros en las cajas municipales de ahorro y crédito (CMACS) del Perú - 2009
Authors: Carita Monroy Fidel
Published: November 2020

optimizar los rendimientos del capital invertido, como resultado de un manejo adecuado de los flujos de activos y pasivos financieros involucrados en la esencia del negocio: Captaciones y colocaciones.

En los últimos 10 años las CMACs en el Perú muestran decrecimiento en su rentabilidad: razón que hace necesaria la implementación de un modelo de dirección que permita corregir este problema.

En este contexto se plantea el modelo GHAP, como un proceso holístico, sistemático y continuo en su estructura y en cada una de sus partes. Por lo tanto, obedece a una perspectiva integral (del todo), ordenada e iterativa.

Este modelo es ergódico y autopoiético; se establece y sustenta en tres componentes: de procesos, de redes y estructuras funcionales y de recursividad.
