IMPRESSION AS A PROBLEM IN MILITARY PSYCHOLOGY
Authors: Papucha M.
Published: July 2020

Psychological problem of an impression seems to be one of the most important problems in military psychology, its correct understanding will mean successful reference-points both in military operations and in coping with consequences of participation in hostilities, particularly PTSD. We consider concept of «impression» as an artifact which has absorbed enormous amount of nuances of values and senses. It took its place within subtle process of human cognition of one’s own internal world. Research analysis must provide answers about psychological essence of impression, its origin, further fate, disappearance and connections with other elements of psyche. We cannot agree with concept of an impression being referred as an image. In any case, even if we can speak about an image (focus on spontaneity and integrity of an impression is definitely suitable here), then it couldn’t be neither visual nor auditory; even if the impression is an image, then it is an amodal image of the world (A. N. Leontiev). Impressions occur to be related to perception, but at the same time are not reduced to the latter. An impression has very close and obvious relations to emotions and feelings. Experience indicates about pronounced individual character of impressions. It is reflected in the fact that not every complex irritant can facilitate emergence of one’s impression. On the other hand, different people in the same impression-causing situation can get very different impressions. Impressions remain as memory traces and personal experience accumulators.
MEANING OF LIFE STATES: THEORETICAL CONSIDERATIONS AND EMPIRICAL TYPOLOGY
Authors: Karpinski K.
Published: July 2020

The article presents the results of theoretical and empirical research devoted to the psychological regularities of the formation of the individual as a subject of life in the process of solving meaning of life tasks. This class of tasks of personal development includes the search, preservation and practical implementation of the individual meaning of life. Psychological indicators of the process and the results of solving life meaning tasks are subjective experiences of meaningfulness of life and crisis of meaning. In order to denote the integral form of feedback functioning in the system of self-regulation of the individual as a subject of life, the concept of «meaning of life state» is proposed and theoretically substantiated. Meaning of life states are understood as a specific category of permanent mental states that reflect the status of the subject-object relationship of the individual with his own life. Contrary to the common in psychological science notions of incompatibility and mutual exclusiveness of experiences of meaningfulness of life and meaning of life crisis, the hypothesis that the meaning of life is a specific form of conjugation and integration of these subjective experiences is theoretically argued. On the empirical material it is shown that there are typical combinations of these experiences, which form stable meaning-life states of the person: prosperous, crisis, conflict and stagnant. It is established that the dominant type of the meaning of life state of a person depends on its internal position in relation to the meaning of life tasks, expressed by their acceptance or non-acceptance, as well as on the productivity of their solution in everyday life. As a promising line of development of the present study longitudinal strategy, designed to reveal the psychological mechanisms and regularities of their mutual transitions and transformations, which are conditioned by the dynamics of solving meaning of life tasks.

Published: July 2020

VANET plays an important role in the Security terms. VANET network is due to their unique features like as a high dynamic network (topology) and Mobility prediction. It attracts so much attention to the industry. VANET wireless networks are rapidly increased commercial and academic interests. Mobile connectivity, Traffic congestion management and road safety are some applications that have arisen within this network model. The routing protocol is a reactive type which means if there is data to be sent then the way will create. On-demand Distance Vector routing protocol is a generally used network topology based on rules for VANET. In surveyed of the routing protocol implemented a balance AODV method used for identifying the malicious nodes in the network. A balanced AODV routing method is defined with following characteristics:- (i) Use of threshold adaptive according to the network situations and balance index i.e node nature. (ii) Detect the malicious node in the network. (iii) Detection and prevention methods in real-time and independent on each vehicle node. In research paper, implement a B-AODV routing protocol and RSA method for detection and prevention the malicious node in the vehicular network. In this proposed algorithm, each vehicle node is employing balance index for acceptable and reject able REQ information’s (Bits). The consequences of the simulation tool in MATLAB (Matrix Laboratory) indicates BAODV and RSA method is used to detect and prevent the flood attach and loss of network bandwidth. Comparison between AODV, BAODV, RSA in normal phase defines B-AODV is exactly matched with AODV in the vehicular network and performance analysis overhead, an end to end delay and packet delivery rate.
Review of Clocked Storage Elements in Digital Circuit Design

Storage of digital circuit is "state" or memory. These are called sequential circuits. The most fundamental sequential circuit type that we will ponder is known as the Flip-Flop. It is ponder four distinct assortments of these gadgets and their utilization in registers and register documents, which can be considered as one type of on– CPU memory. The traditional memory, called RAM, is ordinarily not on the CPU chip. Regular Slam and its assortments, including RAM, ROM, SRAM, Measure, and SDRAM. True single-phase clock (TSPC) method of reasoning has found wide use in advanced plan. At first as a quick topology, the TSPC structure in like manner eats up less power and includes less areas than various systems. In flip-flop plan only a single transistor is being clocked by short heartbeat get ready which is known as True Single Phase Clocking (TSPC) flip-flop.
Pseudoprospective Evaluation of UCERF3-ETAS Forecasts during the 2019 Ridgecrest Sequence

Published: July 2020

The 2019 Ridgecrest sequence provides the first opportunity to evaluate Uniform California Earthquake Rupture Forecast v.3 with epidemic-type aftershock sequences (UCERF3-ETAS) in a pseudoprospective sense. For comparison, we include a version of the model without explicit faults more closely mimicking traditional ETAS models (UCERF3-NoFaults). We evaluate the forecasts with new metrics developed within the Collaboratory for the Study of Earthquake Predictability (CSEP). The metrics consider synthetic catalogs simulated by the models rather than synoptic probability maps, thereby relaxing the Poisson assumption of previous CSEP tests. Our approach compares statistics from the synthetic catalogs directly against observations, providing a flexible approach that can account for dependencies and uncertainties encoded in the models. We find that, to the first order, both UCERF3-ETAS and UCERF3-NoFaults approximately capture the spatiotemporal evolution of the Ridgecrest sequence, adding to the growing body of evidence that ETAS models can be informative forecasting tools. However, we also find that both models mildly overpredict the seismicity rate, on average, aggregated over the evaluation period. More severe testing indicates the overpredictions occur too often for observations to be statistically indistinguishable from the model. Magnitude tests indicate that the models do not include enough variability in forecasted magnitude-number distributions to match the data. Spatial tests highlight discrepancies between the forecasts and observations, but the greatest differences between the two models appear when aftershocks occur on modeled UCERF3-ETAS faults. Therefore, any predictability associated with embedding earthquake triggering on the (modeled) fault network may only crystalize during the presumably rare sequences with aftershocks on these faults. Accounting for uncertainty in the model parameters could improve test results during future experiments.

Os quatro grandes desafios ao modelo de Ciência Aberta: (des)acreditação, informalidade, comodificação e predação
Authors: Lima Quintanilha Tiago
Published: July 2020

RESUMO:O modelo de Ciência Aberta, erguido da vontade de democratizar a produção e acesso ao conhecimento científico, surgiu no início do novo milênio como forma de combater o obsoletismo e fechamento da cultura acadêmica tradicional. Mais de uma década depois, cedendo não só às suas fraquezas idiossincráticas, como também à indústria parasitária e do lucro, o modelo de Ciência Aberta passou a enfrentar quatro grandes desafios que são simultaneamente um problema de (des)acreditação do conhecimento produzido, de informalidade das estruturas de avaliação e validação, de comodificação do conhecimento, e de predação do modelo de acesso aberto. Neste texto tentamos perceber aquilo que está na base desses desafios.

PALAVRAS-CHAVE: ciência aberta; desafios; (des)acreditação; informalidade; comodificação; predação.

 

ABSTRACT: The Open Science model arose in the beginning of the new millennium from the will to democratize the production and access to scientific knowledge, as a means to fight the obsolete/closed character of traditional academic culture. After more than a decade, conceding not only to its own idiosyncratic weaknesses, but also to a profit-seeking industry, the open science model now simultaneously faces four major challenges: the (dis)accreditation of the scientific knowledge produced, the informality of its validation structures, the commodification of knowledge, and the predation of the open access model. In this essay, we try to understand the basis of these challenges.

Do seu vasto currículo destaca-se sua mais recente experiência como pesquisador associado na Universidade de Luxemburgo, de dezembro de 2016 a março de 2019, em projeto de pesquisa industrial com uma empresa privada usando técnicas de aprendizado de máquina. Estabelecemos contato quando o pesquisador recém chegou ao Brasil, após estadia em Luxemburgo. Na ocasião eu estava produzindo uma reportagem sobre “tecnologia e educação” para um projeto de ensino do qual participo, voltado para a produção textual em gêneros jornalísticos por acadêmicos/as e pós-graduandos/as em Letras, da Universidade Estadual de Maringá (UEM). Convidei-o para participar como fonte-especialista em Inteligência Artificial (IA). Dada a complexidade do tema, passei um briefing do meu projeto discursivo e o pesquisador colaborou já na fase preliminar da pesquisa exploratória, sugerindo temas para elaboração das perguntas. A entrevista, concedida em língua portuguesa no dia 14 de abril de 2019, via formulário compartilhado no Google Docs, tem como objetivo tomar os argumentos do pesquisador de modo a localizar a IA como disciplina e área da engenharia, compreender sua especificidade, tendências, impactos na educação e estágio de desenvolvimento no Brasil. Os resultados constantes no texto permitem: i) recuperar a razão da existência da IA – emular a inteligência do ser humano; ii) retomar a classificação tanto como IA simbólica referindo-se à manipulação de símbolos como sistemas de inferência por lógica, quanto como IA conexionista que engloba modelos chamados redes neurais. Entre suas diversas aplicações, destacam-se a tradução automática, reconhecimento de fala e sistemas Q&R; iv) compreender que a popularização do termo IA nos últimos anos se dá graças ao desenvolvimento tecnológico. De acordo com o pesquisador, no mundo do trabalho, poderá ser critério de desempate, transferindo à escola o dever de ensinar o básico de ciência da computação a fim de garantir a empregabilidade. Finalizo minha asserção agradecendo a gentileza do pesquisador ao tornar possível a reelaboração desta temática emergente e urgente que congrega reflexões acerca de tecnologia, educação e trabalho e ao periódico Texto Livre: Linguagem e Tecnologia, que possibilita a circulação desta entrevista na íntegra para uma vasta comunidade, ampliando assim a discussão.
A mozaikcsaládok
Authors: Harcsa István , Monostori Judit
Published: July 2020

A tanulmány a hazai családszociológiai kutatások egyik „fehér foltjával”, a mozaikcsaládokkal foglalkozik. A mozaikcsaládok demográfiai és szociológiai jellemzőinek bemutatását az intakt és egyszülős családokkal ös - szevetve teszi, ezáltal számos ismérv mentén elhelyezi őket a gyermekes családok körében. Mindezek mellett megvizsgálja, hogy mindazon társadalmi hátrányok, amelyek a mozaikcsaládokban élőket jellemzik vajon magával a családszerkezettel vagy a szülők kedvezőtlen társadalmi státuszával függnek össze. Más szavakkal: a mozaikcsaládok társadalmi hátrányait mennyire határozza meg az a tény, hogy az alacsonyabb társadalmi státuszúak nagyobb valószínűséggel kerülnek be a köreikbe. Mindezeket alapvetően két dimenzióban vizsgáljuk: az egyik az anyagi jólét területe, ahol a jövedelmi szegénységet és a megélhetési nehézséget vizsgáltuk. A másik pedig a társas kapcsolatok, ahol a rokoni és a baráti kapcsolatokba való beágyazottság került a kérdéseink fókuszába. Mindkét területen azt állapítottuk meg, hogy a szülők társadalmi struktúrában elfoglalt pozíciójának, nevezetesen ennek egyik fő elemének az iskolai végzettségnek rendkívül erős a hatása, amely számos más ismérv kontrollálásával is megmarad. A mozaikcsaládok kedvezőtlenebb életkörülményeit tehát alapvetően azzal a szelekciós mechanizmussal magyarázhatjuk, hogy az alacsonyabb végzettségűek nagyobb eséllyel élnek ebben a családformában.

Jelen tanulmány célja az, hogy kísérletet tegyen a félelem jelenségének szisztematikusabb és empirikus politikatudományi értelmezésére, és a lokalitások szintjén tanulmányozza a félelem politikájának hatását kvalitatív interjús módszerrel. Az írás arra a kérdésre keresi a választ, hogyan jelennek meg, illetve megjelennek-e egyáltalán a migrációs válsághoz kapcsolódó félelem-narratívák az Ózdon élő munkanélküliek gondolkodásában, emellett milyen más típusú politikai szempontból releváns félelmekkel találkozhatunk a munkanélküliek által elmondott történetekben? A tanulmány legfontosabb megállapítása, hogy bár a migrációs félelmek ténylegesen jelen vannak a munkanélküliek gondolataiban, azonban azok szerepe csupán másodlagos. A migrációs félelmek lényegében „önmagukban állnak”, nem kapcsolódik hozzájuk valódi narratíva, hiszen a személyes élmények hiányát nem képesek pótolni a televíziós tapasztalatok. Az ózdi munkanélküliek a mindennapi életük problémái kötik le, ilyen módon számtalan esetben a bevándorlás helyett éppen az elvándorlás témája kerül középpontba, amelymagába sűríti a létbizonytalanság, a munkanélküliség és a beszűkült életlehetőségek negatív tapasztalatait. Mindemellett egy olyan társadalmi válság bontakozott ki a történeteikből, amelynek alapját az egymással- és az intézményekkel szembeni általános bizalmatlanság, valamint egy veszélyes, bűncselekményekkel teli külvilág képe jelentette. Mindez részben a városban mind a mai napig jelen lévő válságdiskurzus egyik elemeként is értelmezhető.
Az Ezüst Generáció a munkaerőpiacon
Authors: Csoba Judit , Ladancsik Tibor
Published: July 2020

Az idősödő társadalom munkaerőpiaci kihívásainak vizsgálata a nemzetközi és hazai szakirodalom egyik központi témája napjainkban. Az eddigi kutatások a legtöbb esetben az 55–65 évesek munkaerőpiaci jelenlétét elemezték. A nyugdíjkorhatár Európa számos országában napirenden lévő kiterjesztése miatt azonban a 65+ generáció munkavállalási képessége és hajlandósága is kulcskérdéssé vált. A Hajdú-Bihar megyében készültkérdőíves kutatásunk (N=2625, többlépcsős valószínűségi minta) erre a munkaerőpiaci szempontból viszonylag kevéssé kutatott generációra fókuszál. Vizsgálja a formális és informális munkaerőpiacon való szerepvállalást, a 65+ generáció időgazdálkodását és munkavállalását meghatározó tényezőket. Az elemzés során megállapítottuk, hogy a vizsgált célcsoport a formális gazdaságban igen alacsony arányban vesz rész (2,7%) és döntő többségük (93%) az informális gazdaságban sem vállal jövedelemszerző tevékenységet. A minta 68,7%-a esetében azonban olyan költséget kiváltó tevékenységet azonosíthatunk, amelyet kifejezett munkavégzésnek tekinthetünk. Az Ezüst Generáció tagjai tehát lényegesen nagyobb arányban végeznek munkát, mint ami a hivatalos foglalkoztatási statisztikákból kiolvasható. A nyílt munkaerőpiaci szerepvállalást elsődlegesen nem az életkor akadályozza, hanem az iskolai végzettség és az egészségi állapot. Kutatásaink szerint a 65+ generáció munkavállalására azonban a szocio-demográfiai tényezők mellett nagy hatással van az anyagi kényszerek hiánya és az ageizmus is. A megkérdezettek 99,2%-a rendelkezik az egzisztenciát biztosító transzferjövedelemmel, így körükben nincs anyagi kényszer a nyílt munkaerőpiacra való visszalépésre. Mindemellett az időskorúak munkavégzésével kapcsolatos, széles körben elterjedt sztereotípiák a 65+ generációkörében is erősen élnek (interiorizált ageizmus) és jelentősen csökkentik a munkavállalásra irányuló motivációt a formális gazdaságban a generáció munkaképes tagjai körében is.

This analysis of the supplier relationship between Drexel University and Aramark offers a demonstration of the potential for intensifying an anchor institution’s local economic inclusion strategies by leveraging the economic power of supplier partnerships. The operation of a major food service contract represents a substantial set of campus jobs and procurement, but this economic activity often remains outside the remit of economic inclusion efforts when the institution has no contractual influence over it. When an anchor institution can partner with a major supplier that shares a commitment to community impact, it offers opportunities to strengthen an anchor strategy. This article describes how Drexel University and Aramark used their campus food service relationship to deepen Drexel’s anchor mission and core strategic priorities and Aramark’s enterprise sustainability agenda, including the value of the negotiation process, and a set of outcomes in the form of initiatives in food insecurity, local economic inclusion and community engagement, research and technology transfer, and student co-op employment. Both the relationship building process and its outcomes offer a model for other institutions as they look to leverage the untapped economic activity of the major service suppliers.

Published: July 2020

Background: Infections pertaining to mankind particularly those affecting the periodontal tissues are of serious concerns worldwide and are increasing on a global scale particularly in the tropical and subtropical countries like India. The clinical presentation, though very typical of periodontal infection, is often confused with other oral infection, making laboratory diagnosis and confirmation necessary. The management of periodontal infections needs personal hygiene, awareness of infection, proper diagnosis and medication. The present study was undertaken to demonstrate the oral spirochete (Treponema denticola) from periodontal pathogens suffering from periodontal disease.

Methods: A total of 55 clinically diagnosed selected patients of periodontal infection attending the outpatient Department of Periodontics, V. K. Institute of Dental Science, KLE University, Belgaum were studied. Dental plaque was taken as specimens from the patients were processed by modified Fontana staining and observed in microscope.  

Results: A total number of 55 plaque samples were stained by modified Fontana staining technique. 30 cases were positive and 25 cases were negative. Males were affected more as compared to the females and the age group ranging from 15 to 65. Farmers were more affected compared to other occupation.

Conclusions: Microscopic method by modified silver nitrate staining can be a very useful screening method for evaluation of oral spirochetes in a clinical setting if used judiciously keeping in mind the variables that can affect the results.

The COVID-19 outbreak in several countries of the world is facing a challenging task to control the virus transmission as 3.7 million people are tested positive in all over world at the time of writing. India is also suffering with the virus outbreak in different states as on January 30, 2020, India reported its first confirmed case of coronavirus deadly disease (COVID-19) in Kerala state where three students returned from the epicentre of the disease, Wuhan, China. During the first week, India experienced a slow growth in the infected cases but soon after an outbreak has been found in several states and union territories, although strict measures are being made to control the outbreak. This study presents a comprehensive analysis to explore the current status of virus transmission at state and country level, infection growth, most affected age groups, available datasets and prediction models and strict control measures. Several data sources are analysed to collect the pandemic data such as Johns Hopkins University, Ministry of Health, COVID-19 India, Worldometer and media. The analysed study will be significant for scientist, researchers and health workers of India and also for the administrative tasks to consider the different strict measure to control COVID-19.
Knowledge regarding PICC (peripherally inserted central catheter) line care among primary caregivers of PICC line patients undergoing chemotherapy
Authors: Rani Ruchika , Kaur Amandeep
Published: July 2020

PICC lines are widely used for cancer patients receiving chemotherapy. Regardless of various benefits, poor maintenance can cause thrombosis, infections and multiple complications. The role of caregiver is to protect and maintain the patency of central line with early identification of warning signals to prevent complications. A descriptive study was conducted on 55 primary caregivers of PICC line patients to assess the knowledge of primary care givers regarding PICC line care with a view to develop an informational booklet on PICC line care at home in selected areas of tertiary care hospital, Ludhiana, Punjab. A self-structured questionnaire was prepared which was categorized into 4 sub-categories (general knowledge, care of PICC line, complications of PICC line, flushing PICC line) to assess the knowledge regarding PICC line care among primary caregivers. Data was collected using self-report (paper and pen technique) and observation method. Results revealed that majority (56.47%) of primary caregivers were having average knowledge followed by (38.18%) were having good knowledge while (5.35%) had below average knowledge related to PICC line care. The knowledge was found to be more in the category of general knowledge with mean (5.86±1.43) followed by care of PICC line (4.36±0.88) and complications of PICC line (2.98±1.23) and the least knowledge was found in the category of flushing of PICC line with mean (2.25±1.23). Hence it can be concluded that majority of primary caregivers were having average knowledge regarding PICC linecare, indicating the need to develop an informational booklet for caregivers to provide adequate PICC line care at home and prevent further complications.
La “tierra irrigada” y la mercantilización del agua en un nuevo paisaje hídrico de la agricultura pampeana: el caso del clúster de la semilla
Authors: Riera Constanza
Published: July 2020

Desde mediados de la década de 1990 la agricultura extensiva bajo riego creció aceleradamente en la Argentina. Donde tradicionalmente se producía en secano, la adopción de tecnología creó un nuevo paisaje hídrico: la “tierra irrigada”. Para comprender la creación de dicha categoría conceptual y su anclaje dentro de un modelo productivo específico, en este trabajo me propongo analizar la difusión del riego mecanizado en el norte de la provincia de Buenos Aires a partir de las principales políticas públicas que intervienen en esta transformación territorial: el Plan de Mejora Competitiva del clúster de la semilla, el Plan Nacional de Riego y la gestión del agua subterránea para el riego productivo. Recuperando aportes de la ecología política y de los estudios de la ciencia y la tecnología, argumento que la explotación del agua subterránea para riego implica una privatización del recurso que permanece invisibilizada. La “tierra irrigada” contiene dos de los recursos fundamentales para la producción de alimentos que, asociados, se resignifican. El agua adquiere sentido productivo como una mercancía a la que es factible asignar un valor monetario y se privatiza de hecho en el momento de su consumo productivo; mientras la tierra, gracias al agua, se valoriza económicamente al permitir nuevas alternativas de explotación con mayores márgenes de rentabilidad. Así, el agua es el “lubricante” que refuerza el proceso de acumulación.
The South China Sea Dispute: A Reflection of Southeast Asia’s Economic and Strategic Dilemmas (2009-2018)
Authors: Rubiolo M. Florencia
Published: July 2020

The asymmetric distribution of power in the Asian maritime region is favoring China, increasing theapprehension of its neighbors that, faced with their evident vulnerability, fear about Beijing’s intentions. In this context, the balance of power maintains the status quo and limits China’s behavior against other coastal countries. Given the disparity of military and economic power between Southeast Asia and China, this balance can only be achieved with the intervention of an extra-regional power, the United States. The renewed American participation as a guarantor of regional security has created new bonds of strategic dependence for Southeast Asia, which in turn have economies that mainly rely on China. The South China Sea conflict is then posing two dilemmas for the region: China’s increasing economic leverage and Washington’s reactive and challenging Indo-Pacific policy, which might make a stalemate in the maritime conflict possible.

Published: July 2020

Dayflower weeds are tolerant to some herbicides; an alternative for their control is the addition of adjuvants in the solution to be applied to improve the efficiency of these products. Thus, the objective of this work was to evaluate the effect of application of different herbicides with and without adjuvants on the control of dayflower weeds. The experiment was conducted under field conditions in April 2015 on the Santo Azarias Farm, Muzambinho, state of Minas Gerais, Brazil. The area had coffee crops (cultivar Catuaí/Vermelho 144) with plant spacing of 3.00 m × 1.00 m, which had been subjected to a hard pruning. A randomized block experimental design was used, with 9 treatments in 3 blocks, totaling 27 plots. The treatments consisted of four contact herbicides (Saflufenacil 700.0 g kg-1, at 140.0 g c.p. ha-1; Bentazon 600.0 g L-1, at 1.2 L c.p. ha-1; Paraquat 200.0 g L-1, at 3.0 L c.p. ha-1; and MSMA 720.0 g L-1, at 4.0 L c.p. ha-1) and an adjuvant (Nimbus®, mineral oil, 428.0 g L-1) at the rate of 0.3% of the solution volume. The plants in the treatments were evaluated visually by three people every three days, using a scale of grades of control. The plants were weighed every seven days after application of the herbicides to evaluate the percentage of water loss. The treatments MSMA, and MSMA combined with mineral oilpresented the best results for the control of dayflower weeds.

The multiple environmental dynamics of watersheds make these natural spaces interesting objects of study, and in areas with few scientific investigations, such as the Mestre Campo Stream watershed, the need for these investigations is even greater. The accomplishment of this paper sought to characterize the morphometry of Mestre Campo Stream Watershed, located in Piranga City, Minas Gerais, Brazil, as a first activity to create a management plan for the natural resources available in the area. Therefore, TOPODATA geomorphological data were used in a geographic information system (GIS) to extract the morphometric information – area and respective perimeter, length of axis and of drainage network – from the study area and, then, these variables were used to estimate the following indicators: form factor, circularity and compactness indexes, elongation ratio and drainage density, in order to describe the watershed. The morphometric indexes indicated an elongated behavior for the watershed, characterizing it as a space of low susceptibility to flooding under normal precipitation conditions. In addition, the drainage network showed fourth-order ramifications and a median capacity of drainage. The sub-watersheds that makes the Mestre Campo Stream Watershed were also characterized, the Sub-watershed of Brum Stream presented a rounded shape, while the Alto Mestre Campo Sub-watershed presented elongated characteristics. These results highlight the heterogeneity of Mestre Campo Stream Watershed, which must be considered when elaborating the management plan for the studied watershed, respecting the particularities of that geographic space in order to properly explore its natural resources.

The Rh blood group system is a complex blood group which includes different antigen specificities such as c antigen. Anti-c antibody is associated with both acute and delayed hemolytic transfusion reactions as well as hemolytic disease of the newborn (HDN). Rh mediated hemolytic transfusion reactions (HTR) are mostly immunoglobulin G (IgG) mediated and results in extravascular hemolysis and delayed HTR (DHTR). However, we are presenting a case of acute intravascular hemolytic transfusion reaction due to anti-c in a patient with acute subdural hematoma. A 77-year-old woman was referred to our hospital with a loss of conscious and left-sided hemiparesis. After an emergency MRI, she was diagnosed with Acute Subdural hematoma, and an emergency craniotomy was performed. Since Acute Subdural hematoma is a neurosurgery emergency, laboratory technician performed an Immediate-spincrossmatchedd for blood bag to preserve time. During the transfusion of the first packed cell, the patient developed severe hypotension and tachycardia. Thus, the transfusion was stopped. Laboratory results raised the suspicion of an Acute Intravascular Hemolysis. Antibody identification revealed that the patient had an irregular blood phenotype (C2+/c-/E-/e3+/K-), and the presence of alloantigen-c Rh antibody confirmed the suspicion of HTR. In patients with multi transfusion history and pregnant women, pre-transfusion screening of irregular antibodies must be performed. The immediate spincrossmatchh must be prevented in patients with a history of multi transfusions, even in emergency situations.

The aims of this study are to determine the prevalence of sexual dysfunction and to examine the relationships of sexual function and psychological factors of depression and anxiety and diabetes-related factors in Jordanian women with type 2 diabetes mellitus. This study employed a cross-sectional, descriptive, correlational design. All eligible participants with type 2 diabetes mellitus were consequently recruited from primary care centers. All enrolled participants were asked to complete questionnaires: Arabic version of the Female Sexual Function Index, Beck Depression Inventory-II, Beck Anxiety Inventory, and demographic questionnaires. Physical and biological measures were collected from the patient's medical records. 107 women with type 2 diabetes mellitus were recruited with a mean of age of 52.46±8.38 years. The prevalence of female sexual dysfunction was 94.4%. Regarding the mean scores of the Arabic version of the Female Sexual Function Index domains, the highest mean score was for pain (5.09±1.51), and the lowest mean score was for sexual arousal (2.44±1.28). This study found significant inverse relationships between female sexual function and age (r= -0.340, P<0.01), duration of diabetes (r= -0.211, P=0.029), fasting blood sugar (r= -0.234, P=0.015), anxiety (r= -0.375, P<0.01), and depression (r= -0.480, P<0.01). Our study found female sexual dysfunction is widely prevalent in Jordanian women with type 2 diabetes mellitus (94.4%). There were significant correlations between anxiety, depression, and female sexual function among women with type 2 diabetes mellitus.

The aim of this study was to determine the prevalence of overweight and obesity and their associated factors in the female population of Shiraz, South of Iran. This population-based cross-sectional study is based on a screening program on 11850 women referring to a gynecological clinic between 2004 and 2012. Overweight and obesity were defined as a body mass index (BMI) of 25-29.9 kg/m2 and a BMI ≥30 kg/m2, respectively. The mean age of participants was 41.1±10.6 yrs. Mean BMI were 27 kg/m2 (95% CI: 26.90-27.10). The total prevalence of overweight and obesity was 41.4% (95% CI: 40.5-42.3) and 24.10% (95% CI: 23.3-24.9), respectively. In addition, 50-54-year-old women were more likely to have a BMI ≥25 than Youngers. The high prevalence of obesity and overweight in the present study indicates the need for planning preventive programs for the health system in this population.

In this study, we compared regional recurrence in patients who had a dissection of levels I-III or levels I-IV. Patients with tongue SCC who were node-negative both clinically and radiologically, and underwent elective supraomohyoid neck dissection (SOHND) or extended supraomohyoid neck dissection (ESOHND) between March 2012, and March 2015 were retrospectively reviewed. The two therapeutic groups were analyzed for the incidence of tumor recurrence and survival. The two groups had statistically similar demographic qualities. Surgery duration and complications were the same in both groups. Complications mainly included internal jugular vein and thoracic duct injury. Tumour size was 46.2% T1, 40.4 % T2, and 13.3% Tx, being statistically similar in both groups. Tumour size had no meaningful correlation with the occurrence of occult neck metastasis in both groups. Local recurrence was more in ESOHND patients, but regional recurrence was similar in both groups. The survival rate was alike in both groups. No significant differences in tumor recurrence and mortality rate were found between patients treated with SOHND versus ESOHND. Thus, SOHND could be considered as a sufficient treatment for early-stage tongue SCC.

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disease, usually diagnosed with high index of suspicion. The pathophysiology of TTP is due to severe deficiency of von Willebrand factor cleaving protease, known as ADAMTS 13. Early diagnosis is crucial as without treatment TTP is associated with high mortality rate. Plasma exchange is currently the mainstay of treatment. Nonetheless, the classical pentad of microangiopathic hemolytic anemia (MAHA), thrombocytopenia, neurological dysfunction, kidney dysfunction and fever are seen only in 40 percent of the patients. MAHA and thrombocytopenia are the common presenting features. Presentation with thrombotic complication without hematological features (MAHA and thrombocytopenia) is rare and makes the diagnosis difficult. Herein, we report an unusual presentation of a 53-year-old male, who was initially presented in 2014 with classical features of TTP, however had an atypical presentation of TTP in 2016 with only neurological features without hematological features.
Evaluation of Reversed Administration Order of Busulfan (BU) and Cyclophosphamide (CY) as Conditioning on Liver Toxicity in Allogenic Hematopoietic Stem Cell Transplantation (ALLHSCT)
Authors: Ramzi Mani , Namdari Nasrin , Haghighat Shirin , Haghighinejad Hourvash
Published: July 2020

Background: Busulfan (BU) in combination with cyclophosphamide (CY) is used as an effective conditioning regimen in hematopoietic SCT. Busulfan, depletes glutathione level in liver and causes elevated levels of CY metabolites. Cyclophosphamide metabolites are highly toxic for sinusoidal endothelial cells and cause VOD/ SOS with high mortality rate.
Materials and Methods: Between September 2013 and September 2015, all adult patients with acute leukemia who were candidates for myeloablative allogenic SCT and were admitted to Stem Cell Transplantation center were enrolled in this prospective randomized clinical trial. We tested the hypothesis that reverse administration from BU-CY (n=28) to CY-BU group (n=27) would reduce liver toxicity.
Results: Liver function tests were significantly higher in the BU-CY group between day -1 and +4 (p<0.05), but VOD/SOS was not diagnosed in both groups. The incidence and severity of acute GVHD was higher in the BU-CY group, but not statistically significant. Engraftment and mortality rate were not different.
Conclusion: These data support the concept that CY-BU is associated with less liver toxicity, suggesting CY-BU is superior to BU-CY as conditioning.
Short Dysfunctional Telomere is Highly Predictive of Dismal Outcome in MDS but Not in AML Patients
Authors: Menshawy Nadia El , Ashwah Shaimaa El , Ebrahim Mohamed A.
Published: July 2020

Background: A trigger for initiation the clonal hematopoietic stem cells disorders could be short telomere length, probably due to chromosomal instability. The relationship between relative telomere length (RTL) and the two linked hematological stem cell disorders, myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML), is still unclear.
Materials and Methods: We evaluated the role of RTL in MDS (n=96) and AML (n=130) at the time of diagnosis using a real time quantitative polymerase chain reaction (RT-PCR) technique. The median value of RTL (1) was set as the cutoff for statistical comparison. Overall survival (OS) is defined as the time from diagnosis to death or last follow-up.
Results: RTL was significantly longer in both MDS and AML cases versus control (p<0.0001) and was significantly longer in MDS versus AML cases (p =0.03). RTL correlated negatively with age in MDS (p <0.0001) but not in AML cases. RTL was also significantly shorter in MDS cases with pancytopenia and poor risk cytogenetics (p < 0.0001 for each) and short RTL was significantly associated with inferior survival (p = 0.007), while RTL showed no significant impact on OS in AML cases. Moreover, short RTL retained independent prognostic value in multivariate analysis (HR= 3.42 [95% CI, 8.97-19.35], p = 0.004).
Conclusion: RTL showed an association with both AML and MDS; however, short RTL was an independent poor prognostic factor in MDS patients only.
