Accounting Perspective in Hospital
Authors: Meiryani Meiryani , Soepriyanto Gatot , Wahyuningtias Dianka , Dewi Kartika
Published: July 2020

The hospital is an organization whose main purpose is to provide services in the form of examinations, treatment, medical measures and other diagnostic measures needed by each patient within the limits of technological capabilities and facilities provided by the hospital. In addition the hospital also provides consulting services that provide information and advice to patients. Hospitals in carrying out operational and investment activities are inseparable from the costs. Various kinds of services in hospitals incur costs. Transaction cycle in Hospital: (1) Revenue cycle related to providing hospital services to patients or other parties and receiving patient payments or bills from other parties; (2) The expenditure cycle is related to the procurement of goods and / or services from other parties and the settlement of debts and obligations; (3) Production / service cycle related to the transformation of hospital resources into hospital services; (4) Financial cycles related to the acquisition and management of capital funds (capital funds), such as working capital (sources of cash funds or other liquid funds) and long-term funding sources; (5) The financial reporting cycle is not related to the operating cycle as the first four cycles above. This cycle obtains operating and accounting data from another cycle and processes them into financial statements in accordance with generally accepted accounting principles.

The University Challenge in the Collaboration Relationship With the Industry
Authors: Chedid Marcello , Teixeira Leonor
Published: July 2020

Universities suffer from the impact of (1) life cycles associated with technological innovations, (2) the globalization of the economy and culture, (3) the educational needs of an increasingly knowledge-driven society, and (4) the training needs for high-performing professional activities. Solutions to these factors may be found in a positive attitude toward knowledge sharing and collaboration relationships. Collaboration has been considered a way to address the challenges of the 21st century, fostering the necessary innovation, growth, and productivity for all parties involved. Several studies reveal that collaboration can be strongly influenced by knowledge sharing. Collaboration relationships, besides the creation of new knowledge, may result in several outcomes and benefits for the university and society. This chapter aims to address and discuss the university challenges in the collaboration relationships with the industry based on the main results of some empirical studies developed during a research project.

Published: July 2020

Quality test results generated by medical laboratories across the globe are critical for patient diagnosis and treatment. In addition, this is an area of healthcare that requires standardization. Accreditation is the formal recognition by an authoritative body noting that the clinical laboratory has an established quality management system and is competent to carry out specific tasks related to testing. The Strengthening Laboratory Management Toward Accreditation (SLMTA) program was established to strengthen national laboratory systems and to drive improvements that are immediate and measurable in developing countries, particularly those in Sub-Saharan Africa. This review seeks to look at opportunities that can be garnered by accredited medical laboratories and challenges in seeking accreditation during the implementation and operational states of the criteria of ISO 15189:2012. It also examines the progress toward clinical laboratories becoming accredited due to the enactment of the SLMTA in resource-limited settings.
Knowledge Sharing Mediating Information Technology Student Innovation
Authors: Ngugi James Kiarie , Goosen Leilani
Published: July 2020

Research has identified factors promoting innovative behavior (IB) among employees in organizations. However, the effect of knowledge sharing behavior (KSB), self-regulated learning (SRL), and course design characteristics (CDCs) in developing IB among information technology (IT) students in universities is not well understood. The purpose of the study was developing a structural equation model (SEM) of the drivers of IB among IT students. As very little research simultaneously explores the determinants of undergraduate students' IB, one of the study objectives is to plug the literature gap by examining how SRL and CDCs act as antecedents of IB, via the mediating action of KSB. The findings are summated in a KSB-IB SEM. The results largely support all the hypotheses and suggest a significant indirect relationship between SRL and IB, fully mediated by KSB. The indirect relationship between CDCs and IB was significantly and fully mediated by KSB. The results of the study reveal that both CDCs and SRL act as drivers of KSB and IB among IT students.

Towards Disability-Aware Social Media-Enriched Virtual Learning Environments
Authors: Nganji Julius T.
Published: July 2020

The increasing use of social media brings about the need to consider learners with disability when designing learning environments incorporating social learning. Additionally, there is need for educational institutions to consider social media-enriched learning environments. By default, designers and developers of virtual learning environments tend to design for learners without disabilities. The consequences for learners with disabilities are enormous. This chapter aims to propose a disability-aware approach to designing social learning environments that advocates that stakeholders consider the needs of learners with disabilities throughout development. The challenges that learners with disabilities face when interacting with learning systems are reviewed, and a disability-aware approach to designing social learning environments is presented, examining how this could be practically implemented. The opinions and recommendations of 48 students with disabilities from two universities in the United Kingdom and Canada are presented.
Mankind at a Crossroads
Authors: Saavedra-Rivano Neantro
Published: July 2020

The focus of this article is an examination of the impact that sentience of AI systems would have on mankind. Although the notion of sentience for AI systems is subject to controversy, we believe that its plausibility confers a sense of urgency to the kind of exercise developed here. For completeness, the article distinguishes the near-future and longer-term impacts of artificial intelligence. While the short-term impact is deemed to be mostly positive, the outlook for longer-term impact is considered to be negative under a variety of scenarios, including the adoption of man-machine symbiosis tools. The main reason for the negative outlook in the latter case is the heterogeneity of the world. This implies that only a privileged minority would benefit from symbiosis, an outcome that makes likely a world dominated by a minority of “superhumans.” These conclusions should not be taken lightly, and this article endeavors to raise the attention of scientists and policymakers. In this connection, the paper offers suggestions as to policy measures which could avert this disastrous outlook.

Authors: Sarmento Thaisa Sampaio , Gomes Alex Sandro , Moreira Fernando
Published: July 2020

Spatial conditions influence social relations and the development of cultural bonds inside a building. The traditional configuration of most school classrooms must be reconsidered to allow for changes in the educational paradigm to support ICT for learning. It is not clear which environmental aspects should be modified to improve performance in physical learning environments (LE), especially to accommodate hybrid models in classrooms. This article describes the process used to understand education conditions for attending to student needs, the connection between the LE, new technologies, and a social climate favourable to educational changes. This study was carried out in a public secondary school in North-eastern Brazil and adopted a design science research method to perform a participatory design exercise, to develop new classroom environment concepts. The results suggest a set of guidelines for LE suitable for active learning methods, considering activities modalities and environment quality criteria, focused on positive social climate conditions and on ergonomic recommendations.

The loss of killer cell Ig-like receptor ligands (KIR-Ls) due to the copy number–neutral loss of heterozygosity of chromosome 6p (6pLOH) in leukocytes of patients with acquired aplastic anemia (AA) may alter the susceptibility of the affected leukocytes to NK cell killing in vivo. We studied 408 AA patients, including 261 who were heterozygous for KIR-Ls, namely C1/C2 or Bw6/Bw4, for the presence of KIR-L–missing [KIR-L(−)] leukocytes. KIR-L(−) leukocytes were found in 14 (5.4%, C1 [n = 4], C2 [n = 3], and Bw4 [n = 7]) of the 261 patients, in whom corresponding KIR(+) licensed NK cells were detected. The incidence of 6pLOH in the 261 patients (18.0%) was comparable to that in 147 patients (13.6%) who were homozygous for KIR-L genes. The percentages of HLA-lacking granulocytes (0.8–50.3%, median 15.2%) in the total granulocytes of the patients with KIR-L(−) cells were significantly lower than those (1.2–99.4%, median 55.4%) in patients without KIR-L(−) cells. KIR2DS1 and KIR3DS1 were only possessed by three of the 14 patients, two of whom had C2/C2 leukocytes after losing C1 alleles. The expression of the KIR3DS1 ligand HLA-F was selectively lost on KIR-L(−) primitive hematopoietic stem cells derived from 6pLOH(+) induced pluripotent stem cells in one of the KIR3DS1(+) patients. These findings suggest that human NK cells are able to suppress the expansion of KIR-L(−) leukocytes but are unable to eliminate them partly due to the lack of activating KIRs on NK cells and the low HLA-F expression level on hematopoietic stem cells in AA patients.

Authors: González-Santander Juan Luis
Published: July 2020

Se deducen unas expresiones analíticas para calcular la flecha entre una cuerda y una curva lemniscata de Bernoulli. El interés de estas expresiones está en que, en los trazados ferroviarios, las lemniscatas se utilizan como curvas de transferencia entre un tramo recto y otro circular. Es más, según la normativa, la flecha que separa un vagón de la vía no debe exceder una determinada cantidad, por lo que las expresiones deducidas son de gran utilidad en las comprobaciones rutinarias de los trazados ferroviarios.

Determinación de la actividad tóxica de extractos optimizados de Palmaria y Porphyra para el tratamiento de la lesión por isquemia/reperfusión
Authors: Polanco Irisarri David , Padrón Sanz C.
Published: July 2020

La lesión por isquemia-reperfusión (I/R) puede provocar rechazos en los trasplantes de órganos debido al daño a nivel celular que producen los Radicales Libres de Oxígeno (ROS). Se ha comprobado que los antioxidantes naturales pueden reducir este daño. Los extractos de muchas algas poseen una actividad antioxidante notable, pero se necesita comprobar la toxicidad de estos antes de proponerlos como fármacos. En este estudio, se realizaron dos ensayos toxicológicos con queratinocitos humanos inmortalizados (HaCaT) y nauplios de Artemia salina para valorar la toxicidad de dos extractos con actividad antioxidante de Palmaria palmata y Porphyra sp. Se obtuvieron LC50 de 7,843% (v/v) de concentración de extracto en P. palmata en el ensayo con HaCaT y 3,2583% (v/v) en el ensayo con A. salina, mientras que con Porphyra sp. se obtuvo 10,7463% (v/v) en el ensayo con HaCaT y 6,5688% (v/v) en el ensayo con A. salina. Los Niveles Sin Efecto Adverso Observable (NOAEL) obtenidos para cada alga en cada ensayo mostraron significativamente una mayor toxicidad del extracto de P. palmata que del de Porphyra sp. (p < 0,05). Finalmente, se propuso un índice que tiene en cuenta la actividad antioxidante y la toxicidad de cada extracto para predecir su eficiencia in vivo, confirmando los resultados anteriores, y por ello se escogió el extracto de Porphyra sp. como el más idóneo para continuar con los ensayos preclínicos en el desarrollo de un fármaco para el tratamiento de la lesión por I/R.

Haloperidol is known to induce Parkinsonism by blocking dopamine-2 receptors (D2R). However, the mechanism in which Parkinsonism is induced is not well known. In this study, the mechanism of D2R inhibition model of Parkinsonism was proposed via neuromorphological findings observed in primary motor cortex and dorsal striatum. Sixteen female Wistar rats with average weight of 150 g were distributed into 4 groups (NS and -D2I, -D2II, -D2III). Parkinsonism was induced using 5 mg/kg, 10 mg/kg and 15 mg/kg of haloperidol for 21 days. Parkinsonism was accessed with the rotarod and parallel bar. Primary motor cortex (M1) and dorsal striatum (CPu) were processed and stained using haematoxylin and eosin (H&E) and Nissl stains. The density of Nissl bodies was examined with ImageJ software version 1.46. Data was analysed by one way analysis of variance and significant level was set at p ≤ 0.05. The results showed that prolong inhibition of D2R induces Parkinsonism by progressive deterioration of nuclear components, displacement and extrusion of nucleus leading to intracytoplasmic vacuoles in Betz cells of M1. This was projected to be associated with membrane damage. Neurofibrils were proposed to be lost following the numerous shrunken perikaryons observed in M1 and CPu. 70.6% of Nissl bodies were lost to high dose of haloperidol, this was purported to cause decline in protein synthesis and mitochondrial functions leading to decrease in synaptic plasticity and resulting in Parkinsonism.
In-cloud scavenging scheme for aerosol modules
Authors: Holopainen Eemeli , Kokkola Harri , Laakso Anton , Kühn Thomas
Published: July 2020

Abstract. In this study we introduce an in-cloud wet deposition scheme for liquid and ice phase clouds for global aerosol-climate models which use a size-segregated aerosol description. For in-cloud nucleation scavenging, the scheme uses cloud droplet activation and ice nucleation rates obtained from the host model. For in-cloud impaction scavenging, we used a method where the removal rate depends on the aerosol size and cloud droplet radii. The scheme was compared to a scheme that uses fixed scavenging coefficients. The comparison included vertical profiles and mass and number distributions of wet deposition fluxes of different aerosol compounds and for different latitude bands. Using the scheme presented here, mass concentrations for black carbon, organic carbon, sulfate, and the number concentration of particles with diameters larger than 100 nm are higher than using fixed scavenging coefficients, with the largest differences in the vertical profiles in the Arctic. On the other hand, the number concentrations of small particles show a decrease, especially in the Arctic region. These results indicate that, compared to using fixed scavenging coefficients, nucleation scavenging is less efficient and impaction scavenging is increased in the scheme introduced here. Without further adjustments in the host model, our wet deposition scheme produced unrealistically high aerosol concentrations, especially at high altitudes. This also leads to a spuriously long lifetime of black carbon aerosol. To find a better setup for simulating aerosol vertical profiles and transport, sensitivity simulations were conducted where aerosol emission distribution and hygroscopicity were altered. The simulated vertical profiles of aerosol in these sensitivity studies were evaluated against aircraft observations. The lifetimes of different aerosol compounds were also evaluated against the ensemble mean of models involved in the Aerosol Comparisons between Observations and Models (AEROCOM) project. The best comparison between the observations and the model was achieved with the new wet deposition scheme when black carbon was emitted internally mixed with soluble compounds instead of keeping it externally mixed. This also produced atmospheric lifetimes for the other species which were comparable to the AEROCOM model means.
An approach to the verification of high-resolution ocean models using spatial methods
Authors: Crocker Ric , Maksymczuk Jan , Mittermaier Marion , Tonani Marina , Pequignet Christine
Published: July 2020

Abstract. The Met Office currently runs two operational ocean forecasting
configurations for the North West European Shelf: an eddy-permitting model
with a resolution of 7 km (AMM7) and an eddy-resolving model at 1.5 km
(AMM15). Whilst qualitative assessments have demonstrated the benefits brought by the
increased resolution of AMM15, particularly in the ability to resolve
finer-scale features, it has been difficult to show this quantitatively,
especially in forecast mode. Applications of typical assessment metrics such
as the root mean square error have been inconclusive, as the high-resolution
model tends to be penalised more severely, referred to as the double-penalty
effect. This effect occurs in point-to-point comparisons whereby features
correctly forecast but misplaced with respect to the observations are
penalised twice: once for not occurring at the observed location, and
secondly for occurring at the forecast location, where they have not been
observed. An exploratory assessment of sea surface temperature (SST) has been made at
in situ observation locations using a
single-observation neighbourhood-forecast (SO-NF) spatial verification
method known as the High-Resolution Assessment (HiRA) framework. The primary
focus of the assessment was to capture important aspects of methodology to
consider when applying the HiRA framework. Forecast grid points within
neighbourhoods centred on the observing location are considered as pseudo
ensemble members, so that typical ensemble and probabilistic forecast
verification metrics such as the continuous ranked probability score (CRPS)
can be utilised. It is found that through the application of HiRA it is
possible to identify improvements in the higher-resolution model which were
not apparent using typical grid-scale assessments. This work suggests that future comparative assessments of ocean models with
different resolutions would benefit from using HiRA as part of the
evaluation process, as it gives a more equitable and appropriate reflection
of model performance at higher resolutions.

Conceptualizations of the Heart in Jordanian Arabic: A Cognitive Perspective
Authors: Mofarrej Omar Bani , Rabab'ah Ghaleb
Published: July 2020

The present paper examines the metaphorical and metonymical conceptualizations of the heart in Jordanian Arabic (JA) within the framework of Conceptual Metaphor Theory developed by Lakoff and Johnson (1980). The main aim is to explore how the human heart is conceptualized in JA, and to test the applicability of the different general cognitive mechanisms proposed by Niemeier (2003 and 2008) to those found in JA. The data were extracted from Idioms and Idiomatic Expressions in Levantine Arabic: Jordanian Dialect (Alzoubi, 2020), and other resources including articles, dissertations and books of Arabic proverbs. The findings revealed that all the four general cognitive mechanisms suggested by Niemeier (2003 and 2008) are applicable to JA. The findings also showed that the similarity derives from the universal aspects of the human body, which lends tremendous support to the embodiment hypothesis proposed by cognitive linguists.

Authors: Gaxa Luvo , Elliot Hlatshwayo Bafana , Hendry Modishi Magaroleng
Published: July 2020

Introduction: A vallecular cyst is a rare and a benign entity which is readily diagnosed in newborns and in early childhood and is associated with a high morbidity and mortality. The symptoms of a vallecular cyst include but not limited to failure to thrive, voice changes, feeding difficulties, stridor and shortness of breath while in adults the symptoms are commonly mild and the vallecular cyst in the latter tends to be diagnosed as an incidental finding. As early as the prenatal period, vallecular cysts can be diagnosed by using either ultrasonography or magnetic resonance imaging (MRI) scan, MRI scan proves superior and is highly recommended to diagnose and to obtain thorough information regarding the relationship of the cyst to the surrounding anatomical structures and that influences the patient's treatment greatly.
Case Report: We report a case of a seven-year-old boy referred from the peripheral hospital presented with snoring kind of breathing since six months ago. The patient had a difficulty in breathing when sleeping. The patient was able to take meals without any difficulty. No past medical history reported. On examination the oro-pharyngeal mass was noted. Blood pressure 105/57 mmHg, pulse 105 /minute, temperature 36.5°C, weight 13 kg, height 114 cm. The patient had normal developmental milestones. On laryngoscope, a cystic mass in the vallecular region measuring 2.4×2.7 cm and the mass was attached to the base of the tongue, pharyngeal wall and the lingual surface of the epiglottis. The diagnosis on left side vallecular cyst was made on clinical and radiological findings. The cyst was treated by marsupialization and the specimen was sent to the laboratory which confirmed a diagnosis of a vallecular cyst. There was no recurrence of a cyst on our patient's follow-up.
Conclusion: A vallecular cyst shows some typical imaging findings on computed tomography scan and on magnetic resonance imaging scan and a multi-disciplinary approach helps to secure the diagnosis.

Authors: Ghezala Hassen Ben , Salah Snouda , Samia Ferchichi , Fehmi Abbes , Imen Bechikh
Published: July 2020

Introduction: Hemoptysis is a medical emergency. Unusual causes may exist. We report a very rare case of hemoptysis, whose cause has proven an infestation of the respiratory mucosa by a Leech.
Case Report: An 80-year old male presented with a three-day history of hemoptysis. The patient was admitted to our intensive care unit for respiratory distress and hemodynamic instability. Endoscopic examination was performed following nasal packing under local anesthesia and oxygen. A worm was noticed adhered to the bronchial mucosa. This worm was removed under local anesthesia and identified as a leech.
Conclusion: The infestation by the leech remains relatively rare. The diagnosis should be considered in the presence of unexplained hemoptysis, in patients with a recent history of drinking stream water. Endoscopy is the cornerstone in the diagnosis and the treatment of this infestation.

Aims: Congenital clubfoot is a deformity of the lower extremity manifested by foot adduction/inversion, cavus and plantar flexion. Its incidence varies within 0.5–7 per 1000 live births worldwide. Genetic predisposition, environmental factors and combination of them are assumed to have etiological factor. A number of trials have been made to cure clubfoot long years ago. But none of them was as effective as the Ponseti method which is better for success rate and the outcome is affected by many factors. Early diagnosis and treatment should be the main paradigms to decrease the risk of physical disability due to clubfoot. The study was aimed at assessing the practice of management and its outcome. Methods: Facility based retrospective medical record assessment was carried out. The retrieved and qualified data was entered into statistical package for the social sciences for analysis and then output is described and discussed. Results: The basic Ponseti principles and guidelines were practiced in Mekelle hospital considering some limitations. Physiotherapists were the health professionals who make all the clinical decision makings in the setup. The incidence of case relapse was 14.7%, and the rate of tenotomy was 70.6%. However, the facility scored overall success rate of 77.9%. Conclusion: In Mekelle hospital, basic principles and guidelines of Ponseti method were practiced with some deviations. The rate of relapse and failure is also slightly higher. Deep social awareness about clubfoot management, grading the rate of tenotomy and reducing the treatment side effect is mandatory to achieve good outcome.

Authors: Lan Hoang Thi Quynh , Long Nguyen Tien , Hanh Nguyen Van
Published: July 2020

The COVID-19 epidemic has caused higher education institutions in Vietnam to immediately transfer from traditional classrooms to e-learning environments. This interacts with high expectations and habits of learning and training can adversely affect the mental health of students. The purpose of this study is to validate the DASS-21 scale for use in the mental health screening in Vietnamese students when they suffer an immediate psychological reaction in the e-learning environment. Strict statistical analyzes (including Cronbach's alpha, Exploratory Factor Analysis, Confirmatory Factor Analysis, Average Variance Extracted, Average Shared Variance) have led to a well-fitting model of DASS-18 with a three-factor structure to measure the mental health of Vietnamese students in an e-learning environment. Results DASS-18 reported the rates of depression, anxiety, and stress in levels of moderate severity or above in Vietnamese students at 50%, 19.7%, and 37.3%, respectively. However, a rate of anxiety up to 43.1% by using DASS-21 indicating that many students may be misdiagnosed for the level of anxiety. Finally, linear regression analyses are used to examine the influence of socio-demographic factors on the immediate psychological responses of students to an e-learning environment in the context of the COVID-19 epidemic.

Citrus fruit tree has great importance in Brazil. Despite having many commercial cultivars, the lemon crop in Brazil is basically from “Tahiti” cultivar and there is a lack of studies about the characterization and assay of genetic diversity of sweet lemon (Citrus limetta) fruits. Therefore, this work aimed to characterize and evaluate the genetic diversity from nine stock plants produced in Porto Nacional-TO. Fruits in fully physiologic ripening were harvested and evaluated for weight, length, diameter, juice yield, soluble solids content, and color of peel and pulp. The experimental design was completely randomized with 9 treatments (stock plants) and five replications. For the characterization, the data were subjected to Tukey’s test and similarity measure and clustering of the stock plants were performed by Tocher’s method and UPGMA dendrogram. Weight, length, and diameter of all stock plants have not differed from each other. The coordinate b* indicated that stock plant 1 had fruits with peel and pulp clear when compared to the yellow color of the other stock plants. There was genetic diversity between the assessed stock plants and three groups were created, which stock plant 1 and 2 were the most divergent and compose group 3, according to Tocher’s method. The features contributed similarly to total variation.

Two field experiments were carried out at the Experimental Farm of Gemmeiza Agriculture Research Station, Agricultural Research Center (ARC), Egypt after 2018 and 2019 summer growing seasons to determine the effect of intercropping pattern of yellow maize hybrid (single cross 168: “SC 168”) with watermelon pulp at three plant distributions (20 cm between hills and one plant/hill, 40 cm between hills and two plants/hill and 60 cm between hills and three plants/hill) and different levels of nitrogen fertilizer (25, 50, 75 and 100% of the recommended dose “120 kg N fad-1”) as well as their interactions on maize and watermelon pulp growth, yield and its attributes as well as competitive relationships and yield advantages. The experiments were carried out in split-plot design with four replicates. The main-plots were assigned to plant distributions of maize, the sub-plots were allocated to levels of nitrogen fertilizer for maize. The obtained results showed that planting maize plants on one side of terraces of 140 cm width with 20 cm between hills and leaving one plant/hill and planting watermelon pulp on the other side of the terraces produced the highest values of plant height, ear height, number of kernels row-1, 100-kernel weight and grain yield fad-1, at the same time the lowest values of ear leaf area, ear length, ear diameter and number of rows ear-1 of maize as well as the lowest values of growth, yield and its attributes of watermelon pulp during the both seasons. Mineral fertilizing maize plants with 75% of the recommended dose (90 kg N/fad) and watermelon pulp with the recommended dose produced the highest values of all studied growth characters, yield and its attributes of maize and watermelon pulp in both seasons. The highest values of land equivalent ratio (LER), relative crowding coefficient (RCC), area time equivalent ratio (ATER), land equivalent coefficient (LEC), aggressivity index (AI), monetary advantage index (MAI), actual yield (L.E.) of watermelon, Total income (L.E.) and economic return (L.E.) were obtained from planting maize plants on one side of terraces of 140 cm width with 60 cm between hills and leaving three plants/hill and planting watermelon pulp on the other side of the terraces besides fertilizing maize plants with 75% of the recommended dose (90 kg N/fad) and watermelon pulp with the recommended dose in both seasons. It can be recommended that planting maize on 60 cm between hills and leaving three plants/hill and planting watermelon pulp on the other side of the terraces besides fertilizing maize plants with 90 kg N/fad and watermelon pulp with the recommended dose to obtain the maximum values growth, yield and its attributes of watermelon pulp and competitive relationships and yield advantages of both crops under the climates conditions of Middle Delta, Egypt.

An investigation was done to assess the graft success on seedlings and canopy substitution using grafting techniques, retention of basal leaves on the rootstock, age of rootstock and period of grafting in a randomize complete block design with twenty plants per treatment and replicated three times. Young vigorously growing cashew seedlings were used for grafting whilst poor performing cashew trees (in yield and young trees) were stumped to produce shoots for the top working. Significantly (p < 0.05) higher grafting success was obtained for softwood grafting technique in the month of July with October recording the lowest for canopy substitution. Grafting on 60 days old seedlings with the retention of four (4) matured basal leaves on the rootstocks significantly (p < 0.05) gave high success in graft union whilst the root stocks without basal leaves recorded low graft successes. However, there was significant (p < 0.05) off-shoots development below the graft union of the rootstock. Softwood grafting was the best technique for high graft success with the month of July being suitable period for grafting in canopy substitution. Retaining four (4) matured leaves at the base of 60 days old rootstock was the best for achieving high graft success with reduction of infection.

Authors: Diniz Allan Márcio Oliveira , Bueno Janaína Maria
Published: July 2020

O presente trabalho tem como tema principal a gestão de hotelaria hospitalar e os serviços por ela desempenhados com o intuito de demonstrar a sua importância como serviço de apoio no contexto hospitalar, em especial o serviço de lavanderia. O seu objetivo foi analisar a produção científica brasileira na área de hotelaria hospitalar entre os anos de 2013 e 2018, por meio de revisão bibliométrica. Sobre as leis da bibliometria, indica-se que, no presente estudo, a Lei de Lotka não foi confirmada, à Lei de Bradford não foi confirmada e a Lei de Zipf foi confirmada. São diversas as áreas de conhecimento que tratam sobre gestão de hotelaria hospitalar com diferentes enfoques como: enfermagem, medicina, nutrição, psicologia, administração, economia, educação, trabalhando temas como humanização hospitalar, transporte hospitalar, lavanderia hospitalar, higienização e limpeza hospitalar e hotelaria hospitalar em si. Foi possível concluir que, apesar do desenvolvimento do tema, há lacunas, principalmente, no que diz respeito à gestão de hotelaria hospitalar em hospitais públicos.

Introduction: Muscle stretching is
defined as a approach of performing
exercises which improve flexibility of
the muscles. This is an important aspect
of normal human function because it can
influence the amplitude and economy of
a movement.
The aim: The aim of the study was to
reveal the role of stretching among
climbers.
Material and methods:The study
group consisted of 88 rock climbers, in
the range of 24 to 84 years old, including
34 women (39%) and 54 men (61%).
The study was conducted using
anonymous electronic questionnaire.
Results: The question about the
level of advancement in climbing
"beginner level" was declared by 22
(25%) climbers, "medium level" - 31
(35%), "intermediate level" - 23 (26%)
and "advanced" - 12 (14%). The most
frequent parts of the body stretching
through climbers are the shoulder and
upper limb - 42 (48%), lower limb - 27 (31%) and pelvis 19 (21%). Stretching
after each training was used by 39 (44%)
climbers, less than once a week 11

ŚWIADOMOŚĆ ZAWODOWA STUDENTÓW FIZJOTERAPII W GDAŃSKU
Authors: WASILEWSKI Jakub , MICHALSKI Łukasz , WASILEWSKA Agata , PERMODA Andrzej
Published: July 2020

Wstęp.
W 2016 roku w Polsce obowiązywać zaczęła Ustawa o Zawodzie Fizjoterapeuty co niewątpliwie podnosi i ugruntowuje status zawodu w sektorze medycznym. Autorzy poniższej pracy, doświadczeni sytuacją innych zawodów medycznych, a także zaniepokojeni pojawiającą się dezinformacją wśród samych fizjoterapeutów, podjęli się zweryfikowania obecnego stanu wiedzy dotyczącej świadomości zawodowej u studentów fizjoterapii oraz fizjo- terapeutów stawiających pierwsze zawodowe kroki. Badania wstępne.
Cel.
Celem pracy jest weryfikacja i analiza znajomości ustawy o zawodzie fizjoterapeuty w ujęciu świadomości zawodowej.
Materiały i metody.
Badania przeprowadzono w Akademii Wychowania Fizycznego i Sportu im. Jędrzeja Śniadeckiego w Gdańsku. W badaniach udział wzięło 88 studentów studiów stacjonarnych, z czego w pełni prawidłowo wypełnionych formularzy oddało 70 studentów. Kobiety stanowiły 68,5% badanych (N=48), mężczyźni 31,5% (N=22). W badaniu posłużono się specjalnie przygotowanym formula- rzem składającym się z trzech części (metryczką, tabelą z danymi staty- stycznymi, ankietą). Ankieta (załącznik nr1) składała się z pytań zamkniętych, wielokrotnego wyboru o równym poziomie trudności (MRQ).
Wyniki.
Ustawę o zawodzie fizjoterapeuty w całości zna 14%, we fragmentach 49% natomiast 47% przyszłych fizjo- terapeutów nie czytało jej w ogóle. W największym stopniu (47%) badani wykazali się znajomością Obowiązków Fizjoterapeuty. Na drugim miejscu tj. 34% Prawa Fizjoterapeuty, a w najmniejszym (19%) była wiedza dotycząca ogólnych możliwości i działań Krajowej Izby Fizjoterapeutów (KIF). Dzięki wnikliwej analizie badaczom udało się stworzyć Uśredniony Profil Studenta fizjoterapii (ryc.1 UPS).
Wnioski.
Brak uzupełnienia wiedzy pozamedycznej może szkodzić pacjentom jak i wizerunkowi zawodu fizjoterapeuty. Przyszli fizjoterapeuci, w większym stopniu znają swoje zawodowe obowiązki, niż prawa. Internet jest najskuteczniejszym nośnikiem informacji
