Deliberativna komunikacija u zdravstvenoj skrbi
Authors: Jakšetić Dubravka
Published: July 2022

Deliberativna komunikacija u zdravstvenoj skrbi noviji je pojam koji se javio prije tridesetak godina i preuzeo dominaciju u suvremenoj komunikaciji. Ovakva deliberativna procedura temelji se na racionalnoj i obostrano uvažavajućoj raspravi. Osnovna ideja polazi od činjenice da u donošenju odluka sudjeluju sve zainteresirane strane, a temelj je potpuno ravnopravna rasprava svih zainteresiranih subjekata. Nekada je dominirao konzervativni odnos između liječnika i pacijenta, gdje se liječnik ponašao očinski i imao dominantnu ulogu. No u novije se vrijeme sve više razvijaju partnerski elementi u tom odnosu, tako da pacijentu postupno raste partnerska uloga i jača njegova volja i utjecaj. To je prije svega posljedica višeg stupnja obrazovanja, dostupnosti informacija putem medija, razvoja moderne medicine i općenito više razine ljudskog znanja. Stvara se sve viši stupanj jednakosti koja se sastoji od ugovornog ili pravnog i moralnog elementa. Time nastaje odnos partnerstva u kojem postoji opasnost od smanjivanja ili ugrožavanja autoriteta zdravstvenih djelatnika, kredibiliteta i ugleda. Pozitivna je stvar u promicanju ovakvog partnerskog odnosa poštivanje samostalnosti pacijenta, kao i njegovo uključivanje u pojedine dijagnostičke i terapijske postupke.

The patients were divided between a case group consisting of minimally invasively treated patients and a control group of those operated on by conventional surgery. The research data were the following: age, gender, duration of symptoms, type of spinal pathology, type of surgical method, number of surgical levels treated, neurological status, pain intensity assessed by Visual Analogue Scale, duration of surgery and length of hospital stay. Modified Odom’s criteria were used as a primary outcome measure. All data were documented from electronic medical records, statistically analyzed, and correlated between The validity of minimally invasive surgery in treatment of lumbar spine degenerative disease the groups. The level of statistical significance was set at p<0.001.Results: A significant improvement of neurological status after surgery was recorded in all patients (case group, Fisher’s exact test, p=0.002, control group, Fisher’s exact test p=0.012). The pain intensity was significantly reduced after surgery in both groups (case group, Wilcoxon test, p<0.001, control group, Wilcoxon test, p<0.001). A statistically significant difference was observed between the case and the control group in the length of hospital stay (Mann-Whitney U test, p<0.001) and in time elapsed from surgery to patient mobilization (Mann-Whitney U test, p<0.001). In all other data examined, no statistically significant difference was noted between the case and control groups.Conclusion: Surgical treatment of lumbar spine degenerative disease results in significant improvement of neurological status and in reduced pain intensity. Minimally invasive surgery using tubular retractors results in shorter length of stay and earlier patient mobilization.

Authors: Ilmilati Ulya
Published: July 2022

FKDK (Kudus Disability Communication Forum) is a special community for people with disabilities located in Kudus Regency. The problem with FKDK is that the skills possessed by FKDK members are still relatively minimal and they have difficulty finding work. Regarding this, we want to provide knowledge, skills and efforts to improve the economy to the Kudus Regency Disability Communication Forum (FKDK) in the domain of empowering its members. Entrepreneurship training in processing Moringa leaves into hand sanitizers is one form of empowering that we will carry out. On the other hand, the use of Moringa leaves in Kudus Regency is currently still limited. In Menawan Village, there are 5 hectares of land planted with Moringa trees as shade plants. Moringa leaf extract has several ingredients including flavonoids, tannins, saponins, alkaloids, and other phenolic compounds that can function as antiseptics, antibacterials, and antioxidants. This content when mixed in a hand sanitizer will not make your skin hot and irritated.

Marcas de inabilidade em escrita alfabética em uma documentação epistolar de Coração de Maria (Bahia): aspectos da escriptualidade e aspectos da escrita fonética
Authors: Brito Patrícia Santos de Jesus , Lacerda Mariana Fagundes de Oliveira
Published: July 2022

A inabilidade em escrita alfabética tem sido encontrada em diferentes corpora de diferentes lugares e época. Esse fato evidencia que a mão de um redator inábil não é específica de uma época ou lugar, mas de suas caraterísticas atemporais, como afirma Barbosa (1999). Em língua portuguesa, as pesquisas desenvolvidas até o momento têm procurado demonstrar como se opera o controle de marcas de inabilidade e como identificar as mãos inábeis.  Nessa perspectiva, destacam-se os trabalhos de Marquilhas (1996, 2000), Barbosa (1999), Oliveira (2006), Santiago (2012, 2019), entre outros.  Neste trabalho, com base nas referidas pesquisas, fazemos uma descrição, caracterização e análise de marcas de inabilidade em escrita alfabética no corpus Cartas Marienses (Séc. XX) – documentação epistolar de caráter pessoal, escrita no século XX, na região rural semiárida baiana e representativa da vertente popular do português brasileiro (PB), que faz parte do banco de dados Corpus Eletrônico de Documentos Históricos do Sertão – a fim de identificar as mãos inábeis.
Registros da última expedição do Coronel P. H. Fawcett no Brasil: a análise paleográfica de um bilhete (1925)
Authors: Leme Deborah Lavorato
Published: July 2022

Neste artigo nosso objetivo foi utilizar o arcabouço teórico-metodológico da Paleografia para realizar a leitura e análise de um bilhete de autoria atribuída ao explorador britânico Percy Harrison Fawcett, escrito durante sua última expedição ao Brasil em 1925. Fawcett veio para a América do Sul pela primeira vez em 1906 a pedido da Royal Geographical Society para arbitrar o processo de demarcação de fronteiras entre Brasil e Bolívia como uma terceira parte isenta. Depois dessa ocasião ele ainda realizou mais sete expedições no continente sul-americano até finalmente desaparecer em 1925 no interior do estado do Mato Grosso. O bilhete que analisaremos aqui corresponde a um dos últimos indícios do paradeiro de Fawcett que se tem conhecimento até agora.  Em nossa análise consideramos a Paleografia como história da escrita, no sentido de melhor extrair as informações contidas no documento em questão para enriquecer o estudo das fontes referentes à passagem do referido explorador pelo Brasil no começo do século XX.
“[...] mas na lua seguinte se tornou a desconcertar [...]”: aspectos paleográficos e sociohistóricos relativos à saúde mental em uma correspondência oficial do século XVIII
Authors: Pereira Norma Suely Silva , Querino Carla Carolina Ferreira Gomes , Souza Rose Mary Souza de
Published: July 2022

Na perspectiva dos estudos filológicos, o artigo apresenta uma edição semidiplomática de um manuscrito da Bahia colonial e analisa seus aspectos paleográficos e sócio-históricos relativos à saúde mental. Trata-se de um ofício do século XVIII, pertencente ao acervo do Arquivo Histórico Ultramarino, no qual o Vice-rei do Estado do Brasil, 10º Conde de Attouguia, registra o processo de adoecimento psíquico de um agente público da Coroa portuguesa e o seu consequente internamento. Discute-se sobre a importância da correta decifração e transcrição do texto, para o que se faz necessário, tanto o conhecimento do seu contexto de produção e circulação, como a utilização de um referencial transdisciplinar que dê conta da leitura e interpretação da fonte selecionada. No desenvolvimento do estudo, utilizou-se um referencial teórico-metodológico transdisciplinar que integrou a Filologia, a Paleografia, a História cultural, a Terminologia e a Socioterminologia. Para o desenvolvimento da edição, parte-se de um conjunto de normas previamente definidas e explicitadas ao leitor, visando produzir uma edição confiável, que possa se prestar a outros estudos, a exemplo dos linguísticos, literários e históricos. O estudo além de discutir algumas das características da escrita colonial, confirma o caráter estigmatizante que a doença mental já possuía naquele período, evidenciando práticas excludentes, violentas e preconceituosas, revelando a origem de questões sociais e sanitárias que vigoram até os dias atuais.

New Event Based H
∞ State Estimation for Discrete-Time Recurrent Delayed Semi-Markov Jump Neural Networks Via a Novel Summation Inequality
Authors: Cao Yang , Maheswari K. , Dharani S. , Sivaranjani K.
Published: July 2022

This paper investigates the event-based state estimation for discrete-time recurrent delayed semi-Markovian neural networks. An event-triggering protocol is introduced to find measurement output with a specific triggering condition so as to lower the burden of the data communication. A novel summation inequality is established for the existence of asymptotic stability of the estimation error system. The problem addressed here is to construct an H
∞ state estimation that guarantees the asymptotic stability with the novel summation inequality, characterized by event-triggered transmission. By the Lyapunov functional technique, the explicit expressions for the gain are established. Finally, two examples are exploited numerically to illustrate the usefulness of the new methodology.
Accounting Automation: An Experimental Study
Authors: Stoica Oana Cristina , Ionescu-Feleagă Liliana
Published: July 2022

Accounting automation and especially robotic process automation (RPA) has received notable attention from researchers in the past few years. This technology is known as the use of software bots to perform rule-based tasks, which are normally performed by people, such as bookkeeping. Drawing on the theory of reasoned action (TRA) and changing management, the present paper investigates the accounting practitioners’ behavior toward bookkeeping automation through RPA and the extent to which the work experience is a factor that influences this change. Data is collected through experimental cases, having accounting practitioners from Romania as participants. Results show that employees in the accounting sector are more open to automation in comparison to manually working, but the work experience is not an influential factor. Some of the explanations could be related to the respondents’ age and the companies where participants perform their activities. The originality of the study comes from the method used which is rarely used at the level of accounting research, although it could provide objective findings and leaves no room for interpretation. Findings could be of interest to practice as it shows that accounting practitioners are not an obstacle to automation, instead, they are willing to embrace the digitalization changes.

Tornar-se um ativista do clima
Authors: Abajo-Sanchez Camille
Published: July 2022

Este artigo analisa o processo de socialização de jovens iniciados na Extinction Rebellion (XR) em Paris que os transforma em ‘ativistas’ desobedientes, um grupo de ativistas de elite treinados em ação direta não violenta. O artigo baseia-se numa etnografia de cursos de formação em desobediência civil ministrados na XR em 2019 e 2021. Estes cursos são “ritos de instituição”, de acordo com Bourdieu, que consagram ativistas operando uma seleção social. Assim, alguns indivíduos estão dispostos a envolver-se em atividades não violentas devido à sua origem social, ao seu capital cultural ou à sua socialização primária (religiosa em particular). Muito mais do que a transmissão de conhecimentos práticos, o objetivo destes cursos de formação é criar um “esprit de corps”, para utilizar o conceito de Blumer, específico do movimento. O simbolismo dos cursos é mais forte para estes ativistas do que a mera transmissão de conhecimentos técnicos, permitindo a interiorização de uma identidade política coletiva.

Authors: Alkhalifah Zahra
Published: July 2022

Background: Myelolipoma is a benign tumor of the adrenal region. However, it may exist in other regions such as presacral space, gastric, hepatic region, retroperitoneum, nasal cavity, testis, and even in thyroid.
Case Presentation: We present a 55-year-old male who was presented to the emergency department complaining of left lower abdominal pain and diarrhea. Physical examination and echocardiogram were normal. Radiological examination, including non-contrast and contrast CT, magnetic resonance imaging, and positron emission tomography, showed the presence of right paraspinal lobulated soft tissue mass. This finding confirmed the diagnosis of myelolipoma The patient was treated with video-assisted thoracic surgery (VATS), and the mass was examined microscopically and by immunohistochemistry.
Conclusion: Myelolipoma must be considered in the differential diagnosis of mediastinal tumors, it is rare, but it is possible to occur. Differential diagnosis of myelolipoma especially from extramedullary hematopoiesis is necessary. VATS is a feasible and safe treatment option for mediastinal myelolipoma.

Kotoran kucing dibuang menggunakan penyapu (yang digerakkan oleh motor servo) setelah mencapai berat tertentu (yang dideteksi menggunakan sensor load cell). Pakan kucing diberikan melalui saluran yang akan terbuka dan tertutup secara otomatis (yang digerakkan oleh motor servo) berdasarkan pendeteksian ada-tidaknya pakan oleh sensor inframerah. Rentang jarak pengindraan sensor infrared terhadap adanya penghalang pada penelitian ini adalah antara 3 cm hingga 43 cm. Load cell yang digunakan memiliki batas kemampuan penginderaan hingga 5 kg dengan keakuratan hingga 99,73%. Sistem secara keseluruan dikendalikan berdasarkan program yang ditanamkan di mikrokontroler ATMega328p pada modul Arduino Uno R3

Telah dilakukan rancang bangun sistem otomatisasi lampu belajar menggunakan sensor Passive Infrared dan sensor Load Cell berbasis mikrokontroler Arduino untuk mengontrol nyala lampu belajar secara otomatis. Sistem dilengkapi dengan pendeteksi sinar inframerah dari tubuh manusia menggunakan sensor Passive Infrared (PIR) dan penimbang berat badan menggunakan sensor Load Cell, Relay untuk mengontrol arus listrik pada lampu, dan RF433 sebagai komunikasi antar rangkaian. Sistem ini juga bekerja berbasis Arduino sebagai mikrokontroler. Hasil dari penelitian ini menunjukkan bahwa sensor PIR memiliki jarak pembacaan maksimal 6m dan sudut pembacaan maksimal 70o ke kiri dan kanan. Sensor Load Cell dapat menimbang berat badan secara akurat dengan persentase kesalahan 0.61%. Rangkaian keseluruhan pada sistem ini dapat bekerja dengan baik sesuai dengan program perangkat lunak yang dimasukkan, yaitu lampu akan menyala jika sensor keluaran sensor PIR 1 (HIGH) dan berat badan yang dideteksi sensor Load Cell lebih dari 15kg. Sebaliknya alat tidak akan bekerja dan lampu tidak akan menyala jika keluaran dari masing-masing sensor tidak sesuai dengan logika pemrograman.

Karbon aktif merupakan salah satu adsorben yang banyak digunakan sebagai material penjernihan air. Pada umumnya, karbon aktif dapat disintesis dari berbagai limbah biomassa yang tidak digunakan seperti bambu buluh (Schizosachyum brachycladum). Penelitian ini bertujuan untuk mendapatkan suhu karbonisasi optimum sintesis karbon aktif yang dilihat dari penyerapan tertinggi kadar besi pada air sumur gambut. Artikel ini juga menjabarkan Â hubungan antara suhu karbonisasi dan ukuran pori terhadap daya serap karbon aktif. Sintesis karbon aktif diawali dengan proses karbonisasi pada suhu 400, 450, 500, 550, dan 600Â°C (60 menit), kemudian dilanjutkan dengan proses aktivasi dengan mencampurkan bahan baku dengan larutan H3PO4 10% (24 jam) dilanjutkan pemanasan pada 900Â°C (60 menit). Ukuran pori dan morfologi permukaan karbon aktif digambarkan dengan menggunakan scanning electron microscope (SEM). Berdasarkan penelitian yang telah dilakukan, karbon aktif yang dikarbonisasi pada suhu 500Â°C memiliki daya serap dan ukuran pori optimal, dengan efektivitas serapan sebesar 73,03% dengan ukuran pori sebesar 40 Âµm. Semakin besar ukuran pori karbon aktif, maka kemampuannya menyerap Fe dalam air sampel semakin juga semakin besar Penggunaan suhu di atas 500Â°C dapat merusak dinding pori karbon aktif. Dengan demikian, sintesis karbon aktif dari bambu buluh akan optimal jika dilakukan karbonisasi pada suhu 500Â°C

Pada penelitian ini telah dilakukan sintesis dan karakterisasi komposit PANi/ZnO untuk mengetahui karakteristik komposit PANi/ZnO serta membandingkan nilai sensitivitas sensor terhadap gas metanol pada variasi konsentrasi gas metanol yang berbeda. Metode yang digunakan dalam sintesis komposit PANi/ZnO adalah polimerisasi in-situ dengan variasi komposisi ZnO yang digunakan yaitu 10%, 20% dan 30%. Hasil karakterisasi FTIR menunjukkan adanya beberapa jenis ikatan karakteristik PANi/ZnO dari semua sampel hasil sintesis. Pola XRD menunjukkan puncak tertinggi karakteristik ZnO terletak pada 36,19, sedangkan pola difraksi karakteristik PANi terletak pada 31,74Â dengan struktur kristal ortorombik. Morfologi sampel diamati menggunakan SEM hasilnya menunjukkan bahwa sampel PANi/ZnO 30% memiliki struktur ovoidal-shaped dan berpori dengan diamter 378 nm. Hasil pengukuran konduktivitas listrik menunjukkan nilai konduktivitas listrik dari sampel PANi murni memiliki nilai tertinggi yaitu 3,5810-6 S/cm, akan tetapi nilai konduktivitas listrik mengalami penurunan seiring dengan penambahan komposisi ZnO. Penggunaan komposit PANi/ZnO 30% sebagai bahan sensor gas metanol mampu menghasilkan nilai sensitivitas yang relatif tinggi, semakin tinggi konsentrasi gas metanol maka sensitivitas sensor semakin meningkat. Dengan demikian disimpulkan bahwa sampel komposit PANi/ZnO 30% merupakan sampel terbaik sebagai bahan sensor dalam mendeteksi gas metanol.

Insects of the family Neriidae deposited in the Insect Collection of “El Colegio de la Frontera Sur” (Tapachula, México) were revised. Taxonomic revision of 322 specimens provided distributional information about four genera and six species for the state of Chiapas (México). Glyphidops flavifrons (Bigot), Nerius pilifer Fabricius, Nerius plurivittatus Bigot and Odontoloxozus longicornis (Coquillet) are new state records, while Cerantichir enderleini Henning and Glyphidops filosus (Fabricius) are recorded for the first time in Mexico. In order to evaluate species delimitation in Neriidae, 14 landmarks of wing of G. filosus and G. flavifrons were analized with geometric morphometrics. We found significant differences in wing size and wing shape, with evidence of alometric effect. The results suggest that wing morphometrics is a suitable tool in the discrimination of neriid species.

A two-year study was conducted in a conservation area of the Ventania hill system where the Pampean grassy steppes and their headwater springs maintain conditions close to natural ones. The composition and the structure of Chironomidae (Insecta: Diptera) along two short hill pristine streams and their relationship with the physicochemical variables were analyzed. A total of 15444 individuals belonging to 37 species of four subfamilies were identified. An assemblage structure more similar to those described for Andean or Argentine extra-Andean hill streams than to those of the surrounding Pampas was observed. Orthocladiinae showed the highest and Podonominae the lowest taxonomic richness and density. Chironominae was best represented downstream by genera with wide distribution. From the five Podonominae genera reported in the Andean-Patagonic region, three of them (Podonomus Philippi, Parochlus Enderlein and Podonomopsis Brundin) were collected. The presence of Podonomus and Podonomopsis represent the reports at lower altitudes for both genera. The physicochemical variables differed between seasons, and only water conductivity showed an altitudinal gradient. Those species prevailing in piedmont sites correlated positively with conductivity. With few exceptions, the species collected were recorded in both seasons. In Toro stream, density was significantly highest in Spring of the second year. This study provides the ecological and systematic baseline knowledge of an insect group widely used in biomonitoring of aquatic environments, to provide biological information that supports the importance of preserving this area.
