Authors: Košir Katja , Vršnik Perše Tina , Ograjšek Sabina , Ivanuš Grmek Milena
Published: June 2020

V zadnjih desetletjih se tudi v visokem šolstvu vse bolj poudarja pomen na študenta usmerjenega poučevanja, ki se kaže predvsem v spodbujanju študentove aktivne vloge v procesu lastnega učenja. Za spodbujanje smiselnega grajenja znanja pa je treba razumeti učni proces s perspektive študenta. V ta namen smo v kvantitativni raziskavi želele ugotoviti, kako študenti zaznavajo visokošolski pouk tako z vidika spodbujenosti k aktivnemu osmišljanju učnih vsebin kot tudi z vidika povezovanja teorij in raziskovalnih ugotovitev s prakso in urjenja v uporabi informacijsko-komunikacijske tehnologije (IKT). V raziskavi je sodelovalo 212 študentov različnih študijskih programov prve in druge bolonjske stopnje Univerze v Mariboru. Z namenom preveriti različne vidike visokošolskega pouka, kot ga zaznavajo študenti, smo uporabile dva sklopa trditev. Rezultati so pokazali, da študenti zaznavajo dokaj visoko stopnjo spodbude pri aktivnem študiju, še zlasti pri povezovanju novih vsebin z njihovim predznanjem, spodbujenosti k samoorganizaciji učenja ter vključevanju raznolikih primerov, ki so v pomoč pri osmišljanju znanja. Med študenti prve in druge stopnje smo ugotovile nekaj manjših razlik v zaznavah visokošolskega pouka, pri čemer študenti prve stopnje visokošolski pouk zaznavajo ugodneje. Prav tako smo ugotovile nekaj razlik v zaznavah študentov različnih usmeritev.
Možnosti za uporabo na študenta osredinjenih metod poučevanja in učenja bioloških predmetov na UP FAMNIT
Authors: Fišer Živa , Baruca Arbeiter Alenka
Published: June 2020

Za uspešno pridobivanje teoretičnega znanja in globlje razumevanje zgradbe in delovanja bioloških struktur ter pojavov je teoretični pouk bioloških predmetov na vseh stopnjah izobraževanja podprt s praktičnimi vajami. Na visokošolski stopnji so praktične vaje pri posameznih predmetih celo bolj ali manj enakovreden del predavanjem. Na študenta osredinjeni pristopi učenja in poučevanja, podprti z orodji informacijsko-komunikacijske tehnologije (IKT), lahko pripomorejo k učinkovitejšemu razvoju znanja, izjemnega pomena pa so lahko tudi z vidika pridobivanja digitalnih kompetenc pri študentih. Na Fakulteti za matematiko, naravoslovje in informacijske tehnologije Univerze na Primorskem (UP FAMNIT) smo izvedli anketno raziskavo, v kateri smo želeli ugotoviti, kakšne metode poučevanja uporabljajo izvajalci praktičnega pouka bioloških predmetov. Rezultati so pokazali, da le slaba polovica anketiranih izvajalcev v praktični pouk vključuje inovativne metode učenja in poučevanja. Med orodji IKT, po katerih smo spraševali v anketi, več kot 80 % vprašanih pozna in uporablja prosto dostopno virtualno učno okolje Moodle. Mnogi poznajo tudi druge spletne aplikacije, vendar jih ne vključujejo v pedagoški proces. Večina vprašanih je naklonjena uporabi orodij IKT, a jih največkrat ne uporabljajo zaradi stiske s časom ali zaradi njihovega slabega poznavanja.

Thông qua kết quả phỏng vấn sâu 11 người am hiểu là cán bộ kiểm lâm huyện, trưởng thôn, đại diện ban quản lý rừng cộng đồng; phỏng vấn 60 hộ dân, vàthảo luận 8 nhóm nam, nữ và trẻ em tại hai điểm nghiên cứu, đề tài đã xác định được có sự phân biệt giới trong các hoạt động quản lý, bảo vệ và phát triển rừng cộng đồng ở cả 2 nhóm dân tộc Kinh (xã Hương Lộc) và Cơ tu (xã Thượng Quảng). Mức độ tham gia của nữ giới và nam giới trong quản lý bảo vệ và phát triển rừng cộng đồng là không giống nhau và có sự tương đồng giữa 2 nhóm dân tộc. Nam giới thường tham gia vào các hoạt động quản lý bảo vệ rừng nhiều hơn nữ giới. Nam giới hầu như có quyền tham gia và quyết định tất cả mọi việc từ gia đình đến ngoài xã hội như: lập kế hoạch, xây dựng quy ước, tuần tra bảo vệ, phát triển rừng cộng đồng và tham gia lãnh đạo cộng đồng; Trong lúc đó phụ nữ rất ít có cơ hội để tham gia vào các hoạt động trên, đặc biệt là vị trí quản lý cộng đồng. Sở dĩ có sự khác biệt giới như vậy là do 2 nhân tố chi phối: định kiến giới và địa vị xã hội. Tuy nhiên, trên cơ sở phân tích kết quả thì sự khác biệt giới trong hoạt động quản lý bảo vệ rừng và phát triển rừng cộng đồng do địa vị xã hội ở nhóm người Cơ tu rõ nét hơn ở nhóm người Kinh.

ABSTRACT

11 knowledgeable people who were district forest rangers, village heads, representatives of community forest management boards were thoroughly interviewed; 60 households, 8 groups of men, women and children in two research sites were interviewed and discussed; the study identified that there was the gender discrimination in community forest management, protection and development activities in both 2 groups of Kinh people (Huong Loc commune) and Co tu people (Thuong Quang commune). The participation level of women and men was different from these activities, thus there were similarities between the two ethnic groups. Men were more involved in forest protection and  management activities than women. Most men had the rights to participate in and decide everything from their families to social activities such as making plans and regulations, patrolling, protecting and developing community forest and joining community leadership. At the same time, women had few opportunities to participate in these activities, especially community management positions. There were gender differences in the community forest  management, protection and development activities due to two main factors: Gender discrimination and social status. However, based on the analysis of the results, there were gender differences in forest protection and development of community forests due to the fact that social status in the Cotu group was clearer than the Kinh group.

Published: June 2020

eHealth ha permitido mejorar el desempeño de múltiples sistemas de salud alrededor del mundo, a través de estrategias nacionales de integración (estructurada y coordinada) de las Tecnologías de Información y Comunicación (TIC) al sector salud, sin embargo, una vez establecidas las bases para desarrollar e implementar soluciones eHealth, no existe un único camino para que los investigadores, ingenieros, médicos y otros interesados trabajen sobre la creación de soluciones eHealth. Por esta razón, se propone un método con enfoque sistémico-transdisciplinario para el diseño de dispositivos eHealth, con la intención de satisfacer los requerimientos y las necesidades de todos los involucrados en el uso del dispositivo, así como, con la normativa establecida en los diferentes países.

A partir del enfoque sistémico y transdisciplinar, se plantea la elaboración de un método que una sinérgicamente distintos métodos sistémicos, que permita la continua colaboración y compartición de experiencias de los involucrados. En consecuencia, el método permitirá el diseño de dispositivos eHealth que, sin importar su uso, estén apegados a las necesidades del usuario, requerimientos del personal que lo utilizará, normativas y reglamentación del país donde se desarrollen y que brinden la satisfacción total en el dispositivo. Finalmente, el diseño de soluciones eHealth a través del pensamiento sistémico permite, a partir del análisis de las necesidades y requerimientos, entregar un producto que satisfaga a todos los involucrados y sea sustentable, a través de la exploración de diversas perspectivas, la observación del contexto, la participación de los involucrados, discusión y concordancia de intereses.

Published: June 2020

Las turbinas de gas son utilizadas como impulsores primarios en la generación de energía eléctrica. El desempeño de una unidad de turbo gas es dependiente de la unidad de control que tenga, ya que en ella radica gran parte de la optimización en la ejecución del sistema. En este trabajo se presentan los resultados de la evaluación de la estabilidad del controlador en el desempeño de un modelo de un controlador neurodifuso para una unidad turbogás, lo anterior como un primer paso para su aplicación en un proceso real. El diseño del controlador neurodifuso se basa en un controlador PI digital del tipo velocidad. El análisis y evaluación del controlador se hacen mediante simulaciones en tiempo discreto con un sistema de primer orden con retardo. Las pruebas incluyen variaciones de los parámetros del proceso: ganancia, retardo y constante de tiempo. Se evalúa el efecto de perturbaciones determinísticas y estocásticas en la señal de control, la variable manipulada y la variable controlada. Los resultados obtenidos demuestran la factibilidad de utilizar un controlador neurodifuso, integrado en equipos digitales, para aplicaciones reales.

Occupational Deprivation Among Female Survivors of Intimate Partner Violence Who Have Physical Disabilities
Authors: Ballan Michelle S. , Freyer Molly
Published: June 2020

Importance: Women with disabilities face a heightened risk of intimate partner violence (IPV) compared with those without disabilities. The damaging impact of IPV compromises the ability of survivors with disabilities to competently and independently engage in daily occupations.

Objective: To examine the impact of occupational deprivation on survivors of IPV who have physical disabilities.

Design: The findings presented in this article are part of a larger qualitative study. Semistructured interviews were conducted over the course of 18 mo, primarily focusing on questions related to four areas: abuse experience and risk assessment, use and nonuse of self-protective strategies, necessary support services, and impact of disability in relation to these phenomena.

Setting: A nonresidential domestic violence agency serving people with disabilities located in New York City.

Participants: Twenty-five women with physical disabilities receiving services from a domestic violence agency that specializes in assisting people with disabilities.

Results: The findings reported here focus on educational, vocational, financial, and physical barriers to occupational engagement faced by IPV survivors with disabilities.

Conclusion and Relevance: The occupational deprivation experienced by IPV survivors with disabilities can entrap women in abusive relationships, preventing them from independently supporting themselves and their children. Occupational therapy practitioners can provide education and interventions that increase their ability to live independently.

What This Article Adds: This article provides a novel consideration of how occupational therapy practitioners can help survivors with disabilities escape IPV through occupational engagement.
Validation of the Clinical Assessment of Modes–Therapist Version (CAM–T) in Acute Rehabilitation Settings
Authors: Taylor Renée R. , Popova Evguenia S.
Published: June 2020

Importance: Assessments that evaluate health care providers’ communication in acute rehabilitation settings remain scarce; this article contributes to the knowledge base.

Objective: To assess the reliability and validity of the Clinical Assessment of Modes–Therapist version (CAM–T) from the provider’s perspective.

Design: Cross-sectional, psychometric study.

Setting: Acute care and acute inpatient rehabilitation.

Participants: Ninety-six clients and 32 providers (occupational therapy, physical therapy, and nursing).

Measures: The CAM–T was psychometrically evaluated using classical test theory and Rasch analytic approaches.

Results: The findings offer strong evidence for the CAM–T’s reliability and validity for evaluating overall communication and adequate evidence for evaluating individual communication modes.

Conclusion and Relevance: The CAM–T may be used by providers as a self-assessment of communication in occupational therapy and in associated rehabilitation professions.

What This Article Adds: This article offers evidence in support of the CAM–T’s reliability and validity for evaluating health care providers’ communication with clients in acute rehabilitation settings. The CAM–T may be used to evaluate providers’ overall communication and individual mode use as described in the Intentional Relationship Model.
Reliability and Preliminary Outcomes of a Protocol for Selection of Test Accommodations for Higher Education Students With Dysgraphia: A Pilot Study
Authors: Rosenberg-Adler Tali , Weintraub Naomi
Published: June 2020

Importance: Students with dysgraphia often receive test accommodations to enhance their handwriting legibility or speed. However, these accommodations are seldom individualized to ensure that they actually improve the performance of a specific student. Therefore, a need exists for an evidence-based protocol (henceforth, the Protocol) for selecting individually tailored test accommodations for students with dysgraphia.

Objective: To establish the Protocol’s content validity, interrater reliability, and preliminary outcomes through a pilot study.

Design: Descriptive and exploratory design.

Setting: Research laboratory at a large university in central Israel.

Participants: The sample consisted of 25 students (mean age = 24.9 yr, standard deviation = 2.1), of whom 88.0% were male. Inclusion criteria included a previous diagnosis of a specific learning disability and handwriting difficulties. Exclusion criteria were a physical condition or medication intake that may have affected students’ handwriting or typing ability.

Results: The Protocol was found to have face validity and high interrater reliability (κ = .80). Its initial use showed that the most suitable accommodations for students with dysgraphia varied and were not always intuitive (e.g., extended time was not always the best accommodation for students with slow handwriting).

Conclusions and Relevance: The Protocol appears to be a promising tool to assist occupational therapists in selecting the most appropriate accommodations for students with dysgraphia in a systematic manner. However, additional studies are required to further support these results.

What This Article Adds: This study indicates that the selection of the most appropriate accommodation for students with dysgraphia is not always intuitive. It describes a Protocol that enables occupational therapists to select accommodations that are tailored to students’ writing abilities, following a systematic process, while considering the students’ writing performance with and without accommodations.
Continuous methane concentration measurements at the Greenland ice sheet–atmosphere interface using a low-cost, low-power metal oxide sensor system
Authors: Jørgensen Christian Juncher , Mønster Jacob , Fuglsang Karsten , Christiansen Jesper Riis
Published: June 2020

Abstract. In this paper, the performance of a low-cost and low-power methane
(CH4) sensing system prototype based on a metal oxide sensor (MOS)
sensitive to CH4 is tested in a natural CH4-emitting environment at the Greenland ice sheet (GrIS). We investigate if the MOS could be used as a supplementary measurement technique for monitoring CH4 emissions from the GrIS with the scope of setting up a CH4 monitoring network along the GrIS. The performance of the MOS is evaluated on the basis of simultaneous measurements using a cavity ring-down spectroscopy (CRDS) reference instrument for CH4 over a field calibration period of approximately 100 h. Results from the field calibration period show that CH4 concentrations measured with the MOS are in very good agreement with the reference CRDS. The absolute concentration difference between the MOS and the CRDS reference values within the measured concentration range of approximately 2–100 ppm CH4 was generally lower than 5 ppm CH4, while the relative concentration deviations between the MOS and the CRDS were generally below 10 %. The calculated root-mean-square error (RMSE) for the entire field calibration period was 1.69 ppm (n=37 140). The results confirm that low-cost and low-power MOSs can be effectively used for atmospheric CH4 measurements under stable water vapor conditions. The primary scientific importance of the study is that it provides a clear example of how the application of low-cost technology can enhance our future understanding on the climatic feedbacks from the cryosphere to the
atmosphere.
A novel Mie lidar gradient cluster analysis method of nocturnal boundary layer detection during air pollution episodes
Authors: Zhang Yingchao , Chen Su , Chen Siying , Chen He , Guo Pan
Published: June 2020

Abstract. The observation of the nocturnal boundary layer height (NBLH) plays an important role in air pollution and monitoring. Through 39 days heavily polluted observation experiment over Beijing (China) and exhaustive evaluation of gradient method (GM), wavelet covariance transform method (WCT) and cubic roots gradient method (CRGM), a novel algorithm based on cluster analysis of gradient method (CA-GM) of lidar signal is developed to capture the multilayer structure and achieve stability in the nighttime. The CA-GM highlights its performance in comparison with radiosonde data, the best correlation (0.85), the weakest root mean square error (203 m), and the improved 25 % correlation coefficient by the GM. In comparison with long-term experiments with other algorithms, a reasonable parameter selection can distinguish layers with different properties, such as the cloud layer, elevated aerosol layers, and random noise. Consequently, the CA-GM can automatically deal with the uncertainty of the multiple structures and obtain a stable NBLH with a high time resolution, which expected to contribute to air pollution monitoring and climatologies, as well as model verification.
Optimization of Sulfate Aerosol Hygroscopicity Parameter in WRF-Chem version (3.8.1)
Authors: Kim Ah-Hyun , Yum Seong Soo , Chang Dong Yeong , Park Minsu
Published: June 2020

Abstract. A new sulfate aerosol hygroscopicity parameter (κSO4) parameterization is suggested that is capable of considering the two major sulfate aerosols, H2SO4 and (NH4)2SO4, using the molar ratio of ammonium to sulfate (R). An alternative κSO4 parameterization method is also suggested that utilizes typical geographical distribution patterns of sulfate and ammonium, which can be used when ammonium data is not available for model calculation. Using the Weather Research and Forecasting coupled with Chemistry model (WRF-Chem), impacts of different κSO4 parameterizations on cloud microphysical properties and cloud radiative effects in East Asia are examined. Comparisons with the observational data obtained from an aircraft field campaign suggest that the new κSO4 parameterizations simulate more reliable aerosol and CCN concentrations, especially over the sea in East Asia than the original κSO4 parameterization in WRF-Chem that assumes sulfate aerosols as (NH4)2SO4 only. With the new κSO4 parameterizations, the simulated cloud microphysical properties and precipitation became significantly different, resulting in greater cloud albedo effect of about −1.5 W m−2 in East Asia than that with the original κSO4 parameterization. The new κSO4 parameterizations are simple and readily applicable to numerical studies of investigating the impact of sulfate aerosols in aerosol-cloud interactions without additional computational expenses.
Assessing the impact of seasonal-rainfall anomalies on catchment-scale water balance components
Authors: Nasta Paolo , Allocca Carolina , Deidda Roberto , Romano Nunzio
Published: June 2020

Abstract. Although water balance components at the catchment scale
are strongly related to annual rainfall, the availability of water resources in
Mediterranean catchments also depends on rainfall seasonality. Observed
seasonal anomalies in historical records are fairly episodic, but an
increase in their frequency might exacerbate water deficit or water excess
if the rainy season shortens or extends its duration, e.g., due to climate
change. This study evaluates the sensitivity of water yield,
evapotranspiration, and groundwater recharge to changes in rainfall
seasonality by using the Soil Water Assessment Tool (SWAT) model applied to
the upper Alento River catchment (UARC) in southern Italy, where a long time
series of daily rainfall is available from 1920 to 2018. We compare two
distinct approaches: (i) a “static” approach, where three seasonal features
(namely rainy, dry, and transition fixed-duration 4-month seasons) are
identified through the standardized precipitation index (SPI) and (ii) a
“dynamic” approach based on a stochastic framework, where the duration of
two seasons (rainy and dry seasons) varies from year to year according to a
probability distribution. Seasonal anomalies occur when the transition
season is replaced by the rainy or dry season in the first approach and when
season duration occurs in the tails of its normal distribution in the second
approach. Results are presented within a probabilistic framework. We also
show that the Budyko curve is sensitive to the rainfall seasonality regime
in UARC by questioning the implicit assumption of a temporal steady state
between annual average dryness and the evaporative index. Although the
duration of the rainy season does not exert a major control on water
balance, we were able to identify season-dependent regression equations
linking water yield to the dryness index in the rainy season.

The aim of this study was to evaluate the Paspalum oteroi native grass and its adaptive responses to shading and foliar fertilization in two pasture systems in the Cerrado-Pantanal transition region. A completely randomized block design with factorial arrangement was adopted to this study: three types of fertilizers [no fertilization – control (C); Foliar fertilizer for pasture (FF) and Soil fertilizer + Foliar fertilizer (SF)] x two pasture systems (WS - with shading, wooded P. oteroi pasture; NS - no shading, exclusive P. oteroi pasture) with four repetitions. P. oteroi seedlings were transplanted in November 2015. Data collection was from May 2016 to September 2016, during dry season. There were differences (p<0.05) in the sward height variables (H), dry matter (DM), crude protein (CP) content, dry matter production (DMP) and shoot: root ratio (S:R). In the WS system increased of 8,61% of the CP content and fertilizer SF increased of 8.81% of the CP content. However, in the WS system was observed reduced DM, DMP and S:R and in the FF and SF fertilizers increased leaf area index (LAI), in the latter months of the application. Probably, P. oteroi grass developed adaptation strategies to deal with the environmental conditions to which it was submitted during this study, such as variations in its morphophysiological traits: low shoot / root ratio, height, chemical composition, leaf area index e light interception. In conclusion, P. oteroi showed adaptation to wooded pasture systems, during dry period, however, the use of fertilization depends on economic viability studies.
Reconsidering variation and change in the Medieval French subject system
Authors: Wolfe Sam
Published: June 2020

This article draws on a novel corpus of medieval texts to explore diachronic change in the French subject system. It is argued that the relative frequency of null, preverbal and postverbal subjects is affected by changes in the syntax-information structure mapping during the medieval period, with the discourse value of both preverbal and postverbal subjects diachronically variable across the textual records. Furthermore, the discourse value of both so-called Germanic- and Romance- inversion structures is subject to change in the syntax-pragmatics mapping.

Authors: Dick Angela Ngozi , Ugwumgbo Augustine Emeka
Published: June 2020

The 21st century is marked by increased interest in children’s literacy. Part of such academic revolution is more emphasis on child literacy and the increase in the production of Children’s books. Consequently, this research, studies the characteristics of Children’s Literature using the book Leo in the Library. It also understudies the hermeneutics of colour and spelling, showing how the author used them to express children’s innocence. It uses mimetic theory to analyze the book. Thus, it evaluates how the story book Leo in the Library imitates or mirrors the worldview, life and aspirations of children in this century. The research discovered and outlined many characteristics of children’s literature as can be perceived from the book Leo in the Library. They include childlike stories, simplicity of expressions, use of illustrations, attractive colours and pictorial representations, inculturation into social values, shaping the creativity of future writers, centres the child into the possibility of the demand of the emerging world, among others. The writer recommends that children’s literature texts have to be, colourful, didactic, attractive and full of illustrations. This research identifies the characteristics of children’s literature based on Leo in the Library using mimetic theory. It also looks into how child’s innocence is depicted by the use of colour and spelling on the cover page of Leo in the Library as shown in the illustration below.
Taking Family Call: Understanding How Orthopaedic Surgeons Manage Home, Family, and Life Responsibilities
Authors: Higgins Margaret J. , Kale Nisha N. , Brown Symone M. , Mulcahey Mary K.
Published: June 2020

Introduction:

Although women account for more than half of matriculating US medical students, they remain underrepresented in orthopaedic surgery, especially in leadership positions. This may, in part, be due to the disproportionate time spent on household responsibilities by women as compared to men. Understanding whether household responsibilities differ between female and male orthopaedic surgeons is critical to better understand how the demands of family life impacts their careers.

Methods:

A 28-question multiple-choice anonymous online survey was sent via e-mail to 2,107 orthopaedic surgeons practicing at academic institutions in the United States. Survey questions related to the demographics of respondents, respondents' household responsibilities, and childcare methods.

Results:

The survey was distributed to 2,043 orthopaedic surgeons, and 377 responded (response rate: 18.4%). Both female surgeons with and without children reported performing most household tasks, including grocery shopping, laundry, and meal preparation (P < 0.05). There was not a statistically significant difference between male and female surgeons without children who performed household repairs/maintenance in their homes (P = 0.186) and household finances (P = 1.00). Among surgeons with children, significantly more male surgeons completed financial tasks in the home (182 of 252 [72.2%] and 27 of 61 [44.3%]; M versus F, P < 0.0005) and completed household repairs (158 of 260 [60.8%] and 12 of 61 [19.7%]; M versus F, P < 0.0005).

Conclusion:

This study provides a quantitative breakdown of the hours of unwaged household work of male and female orthopaedic surgeons with and without children and asserts that although both male and female orthopaedic surgeons perform unwaged household work, women do substantially more than their male counterparts. Additional household responsibilities, or “family call,” create an environment of competing priorities for female orthopaedic surgeons, which may reduce the time they have to devote to clinical duties and professional advancement.
After Incision, the Skin Knife Blade Is No More Contaminated Than a Fresh Knife Blade

Published: June 2020

Introduction:

The rationale for discarding the skin knife blade and replacing it with another blade for deeper dissection is to prevent bacteria that may be present on the skin from being carried into the deeper layers of the wound. This practice is very controversial because numerous, yet limited, studies exist that support and refute the findings. The purpose of this study was to directly compare the rate of contamination of a skin knife blade with a control blade.

Methods:

We took the surface samples using Replicate Organism Detection and Counting plates of 344 knife blades immediately after making skin incision during the following four types of orthopaedic cases: total hip arthroplasty, total knee arthroplasty, lumbar spine surgery, and cervical spine surgery. At the same time, we sampled 344 control blades. The comparison of positives skin versus control, overall and within each subgroup was done using a bivariate two-sample z-test for the equality of proportions.

Results:

Overall, 35 (5.1%) of the 688 specimens had a positive result. No difference was noted in the rate of positive cultures for the 344 skin blades 4.9% and the 344 control blades 5.2%. No differences were observed in the rate of positive specimens for skin blades (7.4%, 3.4%, 7.7%, and 3.9%) and control blades (2.5%, 4.1%, 7.7%, and 9.2%) for total hip arthroplasty, total knee arthroplasty, C spine, and L spine, respectively. No differences were observed regarding skin prep, room number, case order, room turnover time, or in-room to incision time. Staphylococus species was the predominant bacteria identified.

Conclusion:

We found no evidence to support the theoretical advantage of changing the knife blade after making skin incision to avoid contamination. Contamination rates were the same for both the skin and control blades overall and for all subgroup analysis.
Mathematical Model and Data Analysis to Determine the Number of Confirmed Infections Due to Covid-19 in Spain
Authors: Sanglier Gaston , Cesteros Sonia , Lopez Eduardo J. , Gonzalez Roberto A.
Published: June 2020

Covid-19 initially started in China, although cases of infection by this virus are currently being identified in Europe since January and February of this year camouflaged within a strong outbreak of influenza that had not been identified before. What is certain is that in about a hundred days it has spread around the world threatening humanity. There seems to be a great need to find a rapid response to the speed at which the virus is spreading. In this work, different mathematical models are studied to accurately determine the speed of propagation or infection of people infected by Covid-19 based on data collected from the evolution of the pandemic in Spain. Several mathematical models are proposed and analyzed, but the model proposed as the most suitable is a fourth degree polynomial regression adjustment that presents an R-square statistic of 99.72% which gives a great adjustment of the model for the calculation of the number of infected confirmed by this virus in Spain.  Knowing these data is of vital importance to be able to take and undertake the most urgent health and social measures in an effective and orderly manner. This will have a great repercussion in being able to avoid a high number of possible infections.
Princípio da precaução, irreparabilidade dos danos ambientais e tutela do meio ambiente
Authors: Ravanello Tamires , Lunelli Carlos Alberto
Published: June 2020

O homem, desde os primórdios, degradou o ambiente, causando diversos reflexos negativos. Uma vez lesado o meio ambiente, torna-se muito difícil, ou mesmo impossível, retornar ao estado anterior. Ademais, a reparação pecuniária não se mostra equivalente, vez que o meio ambiente não possui valor monetário. O Princípio da Precaução, enquanto medida preventiva, pode ser medida efetiva para a preservação ambiental. O artigo objetiva analisar o dever de preservação ambiental ante à sua degradação, verificando a previsão constitucional e infraconstitucional em relação ao Princípio da Precaução, além de analisar se o princípio é medida efetiva na proteção do meio ambiente, para tanto, o método abordado será o hermenêutico. Concluiu-se que, o Princípio da Precaução, ao permitir a tomada de medidas que evitem danos ao ambiente, mesmo sem certeza científica, é meio hábil para tutelar o meio ambiente, não podendo, contudo, dissociar-se da proporcionalidade.
O caso Raposa Serra do Sol no Supremo Tribunal Federal: uma análise a partir do procedimentalismo democrático de Habermas e Nino
Authors: Petters Melo Milena , Burckhart Thiago Rafael
Published: June 2020

Desde a promulgação da Constituição de 1988 houve um exponencial aumento de casos judicializados no âmbito do controle de constitucionalidade relativos aos direitos de povos indígenas. O caso Raposa Serra do Sol (PET 3.388/RR), julgado em 2009 pelo STF, pode ser considerado o de maior repercussão jurídica. Neste caso, o STF atuou como legislador ativo ao criar 19 salvaguardas institucionais, além da tese do “marco temporal”, que passaram a ser utilizadas noutros casos como argumento jurídico para restringir direitos de povos indígenas, não obstante a contestação por parte de juristas, antropólogos e instituições indigenistas. Desse modo, nascem interrogativos sobre os limites da atuação da Suprema Corte no âmbito do controle de constitucionalidade, sobretudo no que diz respeito à sua legitimidade no caso em questão. A análise insere-se no campo da teoria constitucional e da teoria política, sendo realizada com base nas teorias do procedimentalismo democrático de Jürgen Habermas e Carlos Santiago Nino.
