Analysis of Waiting Time for Patient Service Using Lean Concept in Outstanding Installations Stella Maris Hospital, Makassar City in 2022
Authors: Janna Nur Miftahul , Sartina Ayu , Elly Aprilia
Published: January 2022

There is a growing worry among hospitals throughout the globe about the impact of outpatient services, which account for a considerable portion of their total income and are predicted to overtake their inpatient counterparts. As more people seek medical attention in the future, this might lead to more money coming in to the hospitals. The goal of this study is to use the lean concept to assess patient service wait times at Stella Maris Hospital Makassar's outpatient department. Mixed methods were used in the research, which included measuring the wait time for patient services for up to 100 patients and interviewing eight informants, including the head of the outpatient installation, the admission officer, three nurses, and the hospital director, all of whom were interviewed (3 people). Data reduction, data visualization, and conclusion writing were used to examine the respondents' replies. A patient care process flowchart is constructed to evaluate the data's quality. rs had not installed an rs sim, which resulted in long lines at the pick-up counter, doctors being late, and patients being unable to pick up their orders on time. It is also essential that hospital SIMRS be linked to each other throughout the whole facility, that repairs are made, and that the results are quantified and can be used for decision-making purposes.

Authors: Rahman Sarimagfirah , Saleh Saleh , Idawati Idawati
Published: January 2022

This study aims to describe the form and form of linguistic representation in the CNN Indonesia news text by using social change analysis from Norman Fairclough. The focus of this research is text analysis, text production, and sociocultural analysis with data in the form of grammatical features. This research is a discourse analysis study in the form of critical discourse analysis (AWK). The data source of this research is CNN Indonesia online media which contains words, phrases, clauses, and sentences. The research data was obtained by using documentation, reading, and note-taking techniques. The results show that there are grammatical features which include: (1) modality, (2) negation, (3) sentence mode, (4) transitivity, (5) personal pronouns, and (6) passivity which represents the form of linguistic representation through power in in the news text. Judging from the production of the text, it is shown that the producer of the text in presenting the news cannot be separated from the aspect of domination and power, either power or domination by groups or individuals. In addition, the power in the text serves to strengthen the position of a subject in the text so that the reader is focused on the discourse conveyed by the author of the text. Furthermore, as an implication of the research results, a critical reading enrichment book was compiled.

Haemophilus influenzae pelvic inflammatory disease with tubo-ovarian abscess: case report and literature overview

Background. Haemophilus influenzae (HI) is a known opportunistic pathogen of the respiratory tract, but is also reported as a potential pathogen of the genital tract.

Case. A 34-year-old woman with diffuse abdominal pain was referred to the emergency department. A transvaginal ultrasound and a CT scan revealed a tubo-ovarian abscess (TOA) of the pyosalpinx in the context of pelvic inflammatory disease (PID). Microbiological cultures revealed the presence of non-capsulated HI biotype II. The patient was treated with levofloxacin and metronidazole for 2 weeks. One and a half month later, she was readmitted for laparoscopic drainage and another 10 days of antibiotics.

Conclusion. Over the years, only a few case reports of HI causing a TOA have been published. The reported genital colonization rates are low. HI can be seen as a potential pathogen of the genital tract.

Authors: Gotama Putu Andyka Putra
Published: January 2022

ABSTRAK

Bahasa Bali merupakan salah satu bagian dari kebudayaan Bali. Kita ketahui bersama bahwa bahasa merupakan jati diri pemiliknya (Seloka, 2006: 6). Artinya, bahasa Bali merupakan jati diri dari masyarakat Bali. Oleh karena itu,  eksistensi bahasa Bali merupakan “harta” yang patut untuk dipertahankan. Namun, kenyataannya sekarang bahasa Bali sedikit demi sedikit telah mulai digeser keberadaannya oleh pengaruh bahasa lain. Buktinya adalah generasi muda Bali sekarang nampaknya mulai tidak memperhatikan bahasa Ibu mereka. Sebagian besar generasi muda tidak mengetahui apa arti kata telung benang, selikur, sasur, selaé dan yang lainnya. Oleh karena itu, penelitian ini dibuat dengan tujuan untuk mengetahui bentuk leksikal numeralia dalam bahasa Bali dan strategi pemertahanan  bentuk leksikal numeralia dalam bahasa Bali.

Penelitian ini termasuk ke dalam jenis penelitian kualitatif, dengan pendekatan empiris. Subjek dalam penelitian ini adalah tokoh masyarakat, pendidik (guru dan dosen) bahasa Bali, dan para pemerhati bahasa Bali. Kemudian, metode yang digunakan untuk mengumpulkan data adalah wawancara dan studi kepustakaan dengan teknis analisis data melalui reduksi, klasifikasi, display, dan interpretasi data.

Hasil penelitian menunjukkan bahwa pertama, dalam bahasa Bali terdapat bentuk-bentuk leksika numeralia mulai dari tingkat satuan, puluhan, ratusan, ribuan, sampai pada tingkat pecahan yang paling tinggi. Masing-masing bentuk memiliki nama atau sebutan tersendiri. Kedua, berdasarkan hasil wawancara, teridentifikasi adanya dua strategi yang efektif untuk diterapkan dalam mempertahankan bahasa Bali. Strategi tersebut adalah pembiasaan penggunaan bahasa Bali dalam situasi formal di Bali dan pembiasaan untuk menggunakan bentuk leksika numeralia dalam bahasa Bali pada komunikasi yang terjadi di rumah.

            Berdasarkan hasil tersebut peneliti merumuskan beberapa saran, di antaranya, untuk pemerintah diharapkan untuk lebih memperhatikan kaitannya dengan pemertahanan bahasa daerah, dalam hal ini adalah bahasa Bali, bagi masyarakat diharapkan senantiasa membudayakan penggunaan bahasa Bali dalam komunikasi sehari-hari. Selain itu, diharapkan untuk tetap mempertahankan bahasa Bali sebagai bahasa Ibu, bagi pendidik terutama pendidik bahasa Bali, diharapkan untuk menerapkan pembiasaan komunikasi menggunakan bahasa Bali baik di dalam kelas maupun di luar kelas, Bagi mahasiswa diharapkan untuk membudayakan penggunaan bahasa Bali dalam komunikasi sehari-hari di kampus dan di luar kampus, dan bagi peneliti lain diharapkan tetap melakukan kajian terhadap pemertahanan bahasa Bali, sehingga nantinya akan muncul strategi-strategi lainnya yang dapat diterapkan dalam kehidupan masyarakat.

Influence of accountability pressure on Science, Mathematics and English Language teachers’ classroom practices in senior high schools in Ghana
Authors: Anane Eric
Published: January 2022

In this study I investigated the sources and influence of accountability pressure on science, mathematics and English language teachers, and suggested ways teachers could better adapt their teaching without yielding to teaching to the test practices with its resultant narrowing of the curriculum. The research was conducted within the midlands of Ghana (Ashanti Region) with a cosmopolitan feature. High schools in the Region attract students from all parts of the nation and nearby regions in West Africa. A large sample of teachers (N = 251), made up of 208 males and 43 females were involved in the study. The distributions of teachers in the three core subjects were 87, 88 and 76 for science, English language and mathematics respectively. In this study, the researcher analysed the sources and effects of accountability threats to the various aspects of science, English language and mathematics teachers’ practices in the classroom with means, standard deviations and ANOVA. In the findings, there was pressure on teachers in the three subject categories to increase the performance of students in WAEC examinations. These pressures often came from school administrators, students and parents. It is recommended that school administrators should focus attention on holistic supervision of teachers to develop a well-informed and educated citizenry instead of leading teachers to achieving students’ gains in performance in external examinations. Also, teachers have to be self-efficacious in their day-to-day practices in the classroom and develop proactive attitudes to learning in students rather than drilling and prepping them on test preparation practices.
Relationships among self-knowledge, family influence, career knowledge and senior high school students’ aspirations for entrepreneurial careers in Ghana
Authors: Nyarko-Sampson Eric
Published: January 2022

Making a career choice is a major turning point in the lives of adolescents in senior high schools. For it is in the senior high schools that students are advised or counselled on future worthwhile occupations. The study set to establish the relationship among self-knowledge, family influence, career knowledge level and senior high school students’ aspirations for entrepreneurial careers. Four hypotheses were tested, whilst 1,004 Form 3 senior high school students were selected from 27 senior high schools nationwide using the multi-stage sampling approach. A 71-item questionnaire with an overall reliability of 0.79 was used to collect data. The three dependent variables were found to be significantly related to students’ aspirations for entrepreneurial careers. Again, a positive relationship was found between self-knowledge and aspirations for entrepreneurial careers. It was, therefore, concluded that senior high school students in Ghana rank high regarding their self-knowledge, family influence and career knowledge levels in their aspirations to entrepreneurial careers. It was recommended that students should be equipped with skills or assisted to know and understand themselves well with respect to making career choices, and also entrepreneurship education should be introduced in senior high school curriculum in Ghana. Implications of the study for counsellor education include taking the variables (personal and contextual) into consideration in counselling students on careers..
Pre-service teachers’ attitudes towards information communication technology
Authors: Ayebi-Arthur Kofi , Owusu Kofi Acheaw
Published: January 2022

Integration of Information and Communication Technologies (ICT) into education has been an important concern in many countries. The purpose of the study was to find out the attitudes of pre-service teachers towards Information and Communication Technology. Descriptive survey design was used for this study, and a semantic differential questionnaire with seven options was used to measure the attitudes of preservice teachers towards ICT. Three hundred students drawn from Level 400 of a department in the University of Cape Coast in Ghana were selected to form the sample for the study using the stratified random sampling technique. From the study, the preservice teachers showed positive attitude to ICT with a mean score of five for all the subscales of the questionnaire which translates as ‘slightly important’. The research reviewed that overall, preservice teachers can be categorised at the “understanding and application of process” stage of the technology adoption stages. A further analysis was conducted to find out the predominant stage of technology adoption among the preservice teachers. It was realised that majority of the respondents rated themselves at the “understanding and application of process” stage which was followed by “learning the process” stage. A one-way multivariate analysis of variance was conducted to investigate if the mean differences among stages of adoption of technology and attitudes towards technology being observed are statistically significant. The study revealed that preservice teachers technology adoption stage differed based on their attitudes towards technology. The preservice teachers showed positive attitude to ICT.
Socio-cultural factors: a missing variable in mathematics pedagogy in Ghana
Authors: Davis Ernest Kofi , Seah Wee Tiong
Published: January 2022

This study draws on theories relating to the local aspects of mathematical knowledge and to mathematics pedagogy to explore how the teaching and learning activities carried out in mathematics classrooms in Ghana deal with these aspects. It focussed on the teaching of measurement of money at the primary school level. The primary school level was considered in this study because it is during this period of time that pupils develop the foundation for learning mathematics at higher grade levels. The current Ghanaian primary school mathematics curriculum, three of the popular primary school mathematics textbooks, and lessons from two experienced primary school teachers constituted the main sources of data for the study. The data collected were analysed qualitatively and presented as narrative description with some illustrative examples. The study revealed amongst others that the approaches used by teachers in the lessons observed reflected those suggested in mathematics curriculum and the textbooks, and these approaches pay very little attention to the social and cultural contexts of the pupils. By way of recommendation the authors provide an alternative approach to the teaching of measurement of money in context, based on a three-tier teaching strategy.
Assessing the counselling needs of undergraduate students on multiple-site Sandwich programmes of institute of education, University of Cape Coast
Authors: Nyarko-Sampson Eric , Dabone Kyeremeh Tawiah
Published: January 2022

The study assessed the counselling needs of students on sandwich programmes of the Institute of Education, University of Cape Coast. Two research questions and four hypotheses were answered and tested respectively. A descriptive study in which 207 respondents were selected from four sandwich centres of the Institute of Education, using various sampling techniques and procedures. The Counselling Needs Inventory designed by the investigators were used to collect data. The predominant counselling need of the students was “I need help on how to get along with extrovert spouse”, whilst a majority of them preferred to talk to a counsellor. Statistically significant differences were found to exist between counselling needs by gender, and age with regards to their psychological needs. No statistically significant differences were found among the ages of the respondents and counselling needs such as Financial needs, Marital needs and Educational needs, and among marital status and number of years taught by the respondents and their counselling needs. It was therefore concluded that sandwich students of the Institute of Education, University of Cape have counselling needs. Among recommendations were that authorities/agencies should ensure that professional counselling services are rendered by universities that run programmes in the non-conventional mode. Implications of the study for counselling included the fact that professional counsellors should be attached to multiple sites of sandwich programmes. Again, students on sandwich programmes should be offered similar counselling services as those in the conventional mode.

The implications for counselling for these findings were emphasised.
NÃO MATE AS BIXAS, DEIXE-AS VIVER! PENSANDO O DIREITO À VIDA A PARTIR DOS APONTAMENTOS DE EMMANUELLEVINAS
Authors: Carvalho Thiago Henrique Almeida de , Araújo David Ferreira de
Published: January 2022

O presente trabalho busca refletir, a partir dos apontamentos teóricos de Emmanuel Levinas, o direito à vida, uma vez que alguns “cidadãos de bem” se acham no direito de escolher quem pode e deve viver. Assim, torna-se necessário questionar as constantes mortes e perseguições à comunidade LGBT+, tendo em vista a nossa atual situação política-ideológica heteronormativa que, através do atual presidente da república Jair Messias Bolsonaro e de suas pautas governamentais, faz por disseminar discursos de ódio contra tais minorias. Logo, torna-se fundamental discutir, além do atual cenário compulsório que legitima a heterossexualidade como forma “sadia” de viver a sexualidade, sobre a falta de cuidado com outro e as diferentes forma de viver. Assim, cremos existir somente uma forma de viver nossa sexualidade, fazendo das outras uma “aberração” e “pecado”. Tais idealizações refletem diretamente em formas de violência tanto simbólica quanto física, acarretando em mortes de pessoas LGBT’s. Desta forma, a partir dos apontamentos teóricos de Levinas (2010), refletiremos sobre o não matarás. Não matem as bixas, deixem-as viver e sonhar. Desse modo, para dar sustentação a discussão tecida aqui, seguimos os preceitos da pesquisa bibliográfica, que é desenvolvida diante de material já elaborado, constituído de livros e artigos científicos.
A ARTE COMO MODO DE CONSIDERAÇÃO INDEPENDENTE DO PRINCÍPIO DE RAZÃO
Authors: Viante Caio Miguel
Published: January 2022

O presente artigo tem por objetivo explicitar a concepção de puro sujeito do conhecimento e a concepção de gênio enquanto fundamentos da arte na filosofia de Arthur Schopenhauer. A arte é concebida pelo filósofo como modo de conhecimento independente do princípio de razão.  Se a representação que segue o princípio de razão é válida para ciência, a representação que prescinde desse princípio atua na arte. Por isso a arte como modo próprio de conhecer se distingue da ciência, visto ser uma forma de conhecimento que ergue o homem acima do indivíduo. Ao elevar o homem, arte proporciona um conhecimento puro que propicia um descanso momentâneo das intempéries da existência. Ocorre que, esse conhecimento puro é apreendido e sua posse pertence ao que Schopenhauer chamou de puro sujeito do conhecer. No puro sujeito do conhecer, encontra-se o artista, mas não o artista comum, e sim uma categoria muito particular: o gênio, pois é a ideia que ele almeja e, sua manifestação é exclusivamente artística. O puro sujeito do conhecimento possui duas acepções: (i) a primeira enquanto artista ou gênio; e (ii) enquanto espectador da obra de arte. Nesse artigo buscaremos analisar essas duas acepções dentro da concepção de arte de Schopenhauer.
O CONCEITO DE FILOSOFIA DO DIREITO E A TRANSFORMAÇÃO SOCIAL EM ALYSSON MASCARO
Authors: Baggio Costa Guilherme
Published: January 2022

O presente trabalho objetiva introduzir o pensamento crítico de Alysson Mascaro, por meio dos conceitos de filosofia e filosofia do direito que o autor sintetiza na obra Filosofia do Direito. Com a metodologia qualitativa, de análise bibliográfica, a pesquisa aborda as reflexões sobre a relação complexa existente entre o pensamento filosófico e a materialidade social, e por sua vez, a filosofia do direito como ferramenta conceitual teórica capaz de denunciar a forma-jurídica como legitimadora da reprodução capitalista. A filosofia, tal como uma árvore, possui suas raízes fincadas na tradição histórica com distintos métodos e diversos ramos, entre os ramos, está a filosofia do direito. Destaca-se a tradição marxista como caminho mais alto para pensar o direito e as suas contradições estruturais advindas da transição do feudalismo para a modernidade burguesa. Mascaro apresenta através das categorias marxistas, o desenvolvimento da filosofia do direito crítica na contemporaneidade, que constrói novos horizontes revolucionários para promover, estruturalmente, a transformação social.

Published: January 2022

The non – formal lessons, which take place outside school, teach pupils to cooperate and work in teams, and also they extend the information gained in the lessons. Moreover, they help apply the knowledge in practice, stimulate curiosity, creativity and good behaviour. Changing educational surroundings as well as teachers discipline pupils. The survey has shown that the pupils participate in such lessons willingly because socialising is informal: their activities are organised by the educators and the lessons take place in the museums. Acquiring knowledge through practice, not through theory, is more effective because it stimulates pupils‘ interest in the processes of real life. The idea of the Project " Chemistry and Kitchen " has revealed itself as an inseparable part of education.

The ecological environmental education is one of educational area directly related with safe and clean environment ant to keep it safe. This is so important to humanity. This insists changes of humans thinking and lifestyle. Scientists and educator practices unanimously highlights that for the ecological environmental education has to be paid big attention in the family, espacially in the preschool institution, because the environmental education in the childhood creates the strong foundation for the moral values, practical skilss and forms environmental motives. Also it is very important that in the preshool institutionthis education area would be scheduled and to use for that various tools of education. One of those tools are environmental events, which content considering to the specifity of the environmental education hould be orientate to prior of environmental areas: the pollution and protection of the air: the pollution and protection of the water; the pollution and protection of the soil; Biot (plants and animals) protection; the problem of rubbishes and also the protection from the phisical pollution (e.g. noise).
The empirical research analysed teachers of the preschool institutions the organising of the environmental events experience showed that at the preshool education period teachers organises various environmental events. Today the most often event for the children are various environmental projects, which the most ar about the water, as the component of the environment, its pollution and the protection.Also quite many events ar for animals and plants, their protection and guardenship. Less then half respondents organised projects for the very important and so much emphasizing rubbish problem. Very popular for the preschool children and often are used in the environmental education are exhibitions. They ar very various: drawings, crafts, pictures, creatures. The most of respondents organised exhibitions of rubbishes and its clearing, sorting area, dedicated to the variaty of plants and animals, their guardenship and protection.

Published: January 2022

Clay-supported silver nanoparticles were green synthesized using the aqueous leaf extract of Parkia biglobosa. The phytochemical analysis and FTIR results of the Parkia biglobosa showed that the leaf contains phenol, tanning, and flavonoids, which act as reducing, capping, and stabilizing agents required for the synthesis of the silver nanoparticles. The prepared adsorbent has good morphology, is rich in silica, and contains functional groups suitable for heavy metal binding. The adsorptions of Zn, Cu, and Pb from pharmaceutical wastewater onto the silver-modified clay were studied as an adsorbent dosage and contact time. From the percentage removal results obtained, the adsorbent had up to 99.96%, 99.5%, and 99.44% removal efficiency for Zn, Pb, and Cu, respectively. The present work shows that the synthesized silver nanoparticles supported on local clay can be used as a potentially low-cost adsorbent to remove heavy metal ions from industrial wastewater.

Authors: MAGARIO Ivana , SCILIPOTI José , BRANDOLÍN Salvador Eduardo
Published: January 2022

Carboxylic peroxy acids are organic oxidants of relevance in the cosmetic, food, and agrochemical industries. However, they are traditionally used as intermediaries in a process known as Prileschajew epoxidation and synthesized using sulfuric acid as a catalyst, promoting undesirable reactions on the final epoxides. Therefore, the study of selective catalysts such as enzymes is a topic of interest. In this work, peroctanoic acid synthesis was carried out using n-hexane as the solvent and an immobilized Candida Antarctica Lipase B commercial preparation as the catalyst. On the other hand, the oxidant, hydrogen peroxide was supplied as an aqueous solution, comprising the disperse phase of the reacting system. The reaction progression was quantified by iodometric and cerimetric titration of the peroctanoic acid concentration in the hexane phase. Four different initial amounts of octanoic acid were tested (0.74, 1.57, 10, and 20 millimoles). Substrate inhibition by octanoic acid was observed having at 1.57 millimoles the maximum initial reaction rate. The experimental data were fitted to a ping-pong bi-bi enzymatic kinetic model to estimate the initial reaction rate. Since this system constituted a liquid-liquid (organic-aqueous) two-phase system, the model was evaluated employing the thermodynamic activities of all species involved, assuming phase equilibria with time. The activities of all species were estimated using UNIFAC. As a result, the model was able to reproduce the trend of the initial rate with the change of the initial amount of octanoic acid.

Published: January 2022

The COVID-19 pandemic has thrown our lives out of gear, causing sweeping changes to nearly all aspects of human society. The shift from working or studying from a workplace (offices, colleges and schools) to WFH (Work From Home) or SFH (Study From Home), has been the most prominent change. To study the impacts of this change further, a questionnaire form consisting of 10 questions was circulated, in which 42 people across various age groups participated. Data analysis and visualisation of the collected data was done with the aim of answering the following research questions - whether there was a change in screen time before and during the pandemic, and whether there was any relation between number of vaccine doses taken and people’s decision to return to their workplaces. This study concludes that there was a marked increase in screen time for most people by an average of 2.7 hours. It also discovers that there is a mild positive correlation between the number of vaccination doses taken, and people’s decision to return to their workplaces

Los emisores analizados fueron un total de 20 de 10 fabricantes distintos y caudales comprendidos entre 2.0 y 4.0 l/h. Los tratamientos de riego fueron tres: AR (Agua Regenerada), AR-FR (Agua regenerada + fertilización con solución iónica estándar) y AR-FR-M (Agua regenerada + fertilización iónica estándar + mantenimiento). Los resultados muestran un mejor comportamiento del tratamiento AR-FR-M, no existiendo relación entre índices de calidad y tipo de emisor, aunque si con su forma de inserción. Los goteros compensantes muestran un mejor desempeño. Como conclusión, no se recomienda, en ninguna de las condiciones, fertirrigar sin mantenimiento, ya que, afecta al atascamiento de los emisores y, por tanto, a la uniformidad de la instalación.
Sumergencia en aforadores de pared gruesa mediante las ecuaciones unidimensionales de la Hidráulica clásica
Authors: Sánchez Raúl , Juana Luis
Published: January 2022

Se propone un procedimiento analítico para estudiar la sumergencia de aforadores de pared gruesa mediante la ecuación del equilibrio dinámico. Se determina numéricamente tanto el límite de sumergencia del aforador como la curva de gasto en situación de no sumergencia. En el cálculo de esta se consideran pérdidas de carga por rozamiento sobre el aforador. Los resultados del cálculo se han contrastado experimentalmente en un aforador de realce de solera con rampa de aproximación y salida completamente truncada. La condición de sumergencia que se obtiene, al igual que ocurre con la Ecuación de Gasto del aforador, puede ajustarse mediante una función potencial con objeto de facilitar su uso. La determinación de la sumergencia de un aforador de pared gruesa queda ahora fundamentada en la aplicación de los principios de la Hidráulica. Se mejora así el proyecto de aforadores y el límite de aplicación de la curva de gasto.

When the decisions are analytically supported they cannot be challenged and at the same time, the quality of decision increases. This paper is about proposing such a model which provides the analytical support to the decision for the selection of footwear articles to be produced. This paper aimed to suggest the analytically supported decision-making for deciding the number of pairs of different articles to be produced in a way that the cost and profit could be minimized and maximized respectively. This research was conducted at the ABC leather footwear company of Lahore Pakistan. The data was collected from the costing executive of the planning and costing department. Costing and profit analysis of the collected data was conducted in Microsoft Excel as per the company`s traditional method of calculations. The linear programming (LP) model was then formulated and implemented in Microsoft Excel by using solver add-in. Outputs of both the traditional method and LP model were compared. The comparison revealed that with 22% less production, 39% more profit could be earned if the selection of articles and their production quantity would be calculated accordingly. This model can be modified and used in fast-moving consumer goods (FMCGs) industries for making product mix strategies. A major limitation of the present developed model is that it is based on the scenario of the footwear industry so it cannot be used as general for other applications.

Desde el año 2000, el Zentrum für Mathematik de Bensheim (ZFM) y la Universidad Darmstadt (TUDa) organizan anualmente una escuela de otoño para alumnos con gran talento matemático que cursan el último año de estudios. Durante una semana, los participantes trabajan en grupos sobre problemas de aplicación, que primero hay que matematizar y luego resolver mediante análisis matemático y aproximación numérica. Finalmente, se presentan los resultados. Los problemas son muy realistas. Sólo se pueden omitir detalles menores, para facilitar el manejo del problema y centrarse en la cuestión principal, solo si no afectan al resultado básico. Para algunos de los problemas existen versiones más sencillas, que pueden resolverse en un periodo de tiempo más corto, incluso en un entorno escolar habitual. La resolución de esos problemas sencillos abre la perspectiva a los problemas difíciles si se introducen antes. En este trabajo se examinan dos aplicaciones que llevaron a problemas matemáticos problemas de análisis y geometría.
Cartografía del abandono de cultivos de cítricos mediante el uso de datos altimétricos: LiDAR y fotogrametría SfM

The Comunitat Valenciana region (Spain) is the largest citrus producer in Europe. However, it has suffered an accelerated land abandonment in recent decades. Agricultural land abandonment is a global phenomenon with environmental and socio-economic implications. The small size of the agricultural parcels, the highly fragmented landscape and the low spectral separability between productive and abandoned parcels make it difficult to detect abandoned crops using moderate resolution images. In this work, an approach is applied to monitor citrus crops using altimetric data. The study uses two sources of altimetry data: LiDAR from the National Plan for Aerial Orthophotography (PNOA) and altimetric data obtained through an unmanned aerial system applying photogrammetric processes (Structure from Motion). The results showed an overall accuracy of 67,9% for the LiDAR data and 83,6% for the photogrammetric data. The high density of points in the photogrammetric data allowed to extract texture features from the Gray Level Co-Occurrence Matrix derived from the Canopy Height Model. The results indicate the potential of altimetry information for monitoring abandoned citrus fields, especially high-density point clouds. Future research should explore the fusion of spectral, textural and altimetric data for the study of abandoned citrus crops.

Introdução: A pandemia da COVID-19 trouxe inúmeras incertezas e dentre elas a possibilidade de infecção a partir do contato com superfícies contaminadas. Objetivo: Desta forma, foi conduzido um estudo exploratório a fim de avaliar a presença de material genético do SARS-CoV-2 em superfícies sujeitas à alta manipulação. Material e métodos: Para tal, amostras de swab de superfície foram coletadas em 9 pontos do CIT SENAI e em 26 pontos em um hospital de atendimento à COVID-19 da grande Belo Horizonte. Foram utilizados swabs umedecidos em tampão de coleta e a amostragem foi realizada na maior área possível. Controles artificiais foram produzidos a partir de uma amostra positiva. Para os ensaios foram utilizados os parâmetros previamente validados para o RT-qPCR no laboratório a partir do protocolo CDC (alvos N1, N2 e RP). Resultados: Os controles artificiais produzidos em laboratório foram detectados em CTs aproximados de 33-34, sendo considerados satisfatórios para a técnica validada. Em relação aos pontos de amostragem do CIT SENAI, não houve detecção dos alvos virais, no entanto, foi observada alguma recuperação de material genético humano (RP). Na amostragem do hospital em apenas 8 pontos de coleta foram possíveis a recuperação de material genético humano RP dentro de um limite aceitável (CTs 35-37, sendo 35 o corte original validado para este alvo no laboratório). Em nenhum ponto amostrado foi recuperado material genético viral. Conclusão: Tendo em vista os dados apresentados é possível concluir que a detecção de SARS-CoV-2 em superfícies, apesar de possível, é improvável devido à estabilidade do vírus variar em diferentes tipos de superfícies. Fatores como temperatura, pH, luz solar e o uso de protocolos de limpeza diversos tendem a influenciar nesta estabilidade, não existindo um consenso absoluto sobre a sobrevivência do vírus em superfícies inanimadas.
