Published: June 2022

Tisu merupakan salah satu jenis kertas yang terbuat dari serat kayu. Peningkatan kebutuhan tisu di masyarakat meningkatkan penebangan pohon. Tandan kosong kelapa sawit (TKKS) merupakan limbah dari kelapa sawit yang mengandung selulosa tinggi dan memiliki potensi untuk dimanfaatkan sebagai filler dalam pembuatan tisu. Penelaahan kajian pustaka ini dilakukan untuk mengetahui potensi pemanfaatan nanoselulosa TKKS sebagai filler pembuatan tisu toilet. Sesuai persyaratan, bahan untuk tisu diharapkan mempunyai kandungan selulosa 70 %. Perhitungan kadar selulosa optimum dengan delignifikasi ditentukan dari regresi linear menggunakan software SPSS Statistics 25. Rancangan variabel proses menggunakan software Minitab 19. Metode perancangan yang digunakan dalam percobaan adalah placket burman. Hasil delignifikasi optimum didapatkan pada suhu 150-160°C, NaOH 15-17,5%, dan waktu 20-40 menit. Ukuran diameter nanoselulosa terkecil sebesar 5-10 nm, didapatkan dengan proses hidrolisis asam menggunakan H2SO4 30% pada suhu 60°C selama 120 menit. Nanoselulosa dapat digunakan sebagai filler dalam pembuatan tisu toilet, karena dapat menghasilkan rongga yang dapat menyerap molekul air dan meningkatkan kekuatan lapisan kertas.
Tissue is a type of paper, made from wood fibers. The elevation of tissue necessity in the society will rise the trees logging. Oil palm empty fruit bunches (OPEFB) is waste from oil palm mill which contains high cellulose and has a lot of potential to be used, one of that is as a filler in the manufacture of tissue. The literature review was conducted to determine the potential utilization of cellulose in OPEFB as a filler in the manufacture of toilet paper. According to the requirements, the material for tissue is expected to have a cellulose content of 70%. Estimation of optimum cellulose content with delignification was determined by linear regression using SPSS Statistics 25 software. The optimum delignification results were obtained at a temperature of 150-1600C, NaOH 15-17.5%, and 20-40 minutes. The lowest diameter of nanocellulose is 5-10 nm, obtained by acid hydrolysis using 30% H2SO4 at 600C for 120 minutes. The nanocellulose is used as a filler in the manufacture of toilet paper, because it can produce holes that can absorb water molecules and increase the strength of the paper layer.

Published: June 2022

Los países iberoamericanos afrontan algunos problemas estructurales en el campo de la educación, fundamentalmente en lo que respecta a la repetición, la sobreedad y el abandono, que constituyen auténticos nudos críticos de nuestros sistemas educativos. Podría incluso decirse que la expansión escolar ha tenido el efecto paradójico de crear una nueva exclusión, en este caso educativa, que viene a sumarse a otros factores de riesgo y vulnerabilidad social.
Detrás de estos fenómenos aparece el fantasma del usualmente denominado «fracaso escolar». Este número está dedicado a analizarlo, con la convicción de que se trata de un asunto crucial para nuestro futuro educativo y social. Para ello, como es habitual, contamos con voces relevantes en el panorama iberoamericano que nos ayudan a adentrarnos en su realidad y sus dimensiones desde diversas perspectivas.

El desarrollo de estrategias de aula a través de elementos de comunicación diseñados para mejorar la formación participativa, convierte al aula en la primera red social colaborativa en la que puede diseñarse; no la intervención comunitaria, expresión que no compartimos por sus ingredientes destacadamente conductistas, sino, antes bien, la activación comunitaria, la conexión colectiva, sensible, entre el trabajo personal y grupal de la clase con el desarrollo del conocimiento en la comunidad; la necesidad de crear los valores sociales del conocimiento expuesto en clase, impregnándolos con las necesidades y las preguntas de la propia comunidad.
Universidad privada: ¿del botín económico al botín político?

Resulta evidente que en estos últimos años, algunos dueños de universidades privadas, de maneraabierta, descarada y sin control alguno, vienen orientando sus intenciones y acciones más en función de índole política que académica, en razón del uso y aprovechamiento que se hace de la institución universitaria con fines de proselitismo político, lo que debe ser cuestionado y sobre lo que es necesario alertar, por tratarse de una actitud poco ética e ilegal que va en perjuicio directo, tanto económica como académica, de los estudiantes y de la sociedad, razón de ser de toda Universidad

Paulo Freire falleció el 2 de mayo de 1997, hace ya 20 años; sin embargo, sus planteamientos filosóficos y pedagógicos permanecen vivos. Los intereses que ocuparon la existencia de este pensador brasileño: el ser humano, su incompletud y educabilidad; el conocimiento y sus posibilidades de construcción; el papel humanizador de la docencia; la naturaleza política de la educación y la educación popular; la concientización y su importancia en el proceso de liberación; la eticidad y los valores que entraña el acto pedagógico; la vocación ontológica de ser más y la crítica a una escuela que no educa; la ideología y las instituciones que alimentan la alienación y opresión; la alfabetización como lectura y escritura del mundo; y la participación política como intervención valiente en aras de la transformación social, entre otras inquietudes, llevaron a Freire a producir un cúmulo de textos que hoy representan para sus lectores un valioso legado y un enorme desafío para quien quiere releerlo y reinventarlo.
If I were a teacher…: Concepts of People on the Autism Spectrum About the Education System
Authors: Błeszyński Jacek 
Published: June 2022

Assumptions: This article is part of a wider study on adults with autism. The main assumption of the series of studies is concerned with listening to and hearing the voices of those most affected – those with a diagnosis of autism. The material, which is based on the experiences of people with autism, allows us to present views on the role of the teacher – the creator of the educational space. Thus far, we have presented the experiences and comments of teachers and therapists; now we can listen to the voices of not only students and parents, but people with autism. The research problem was to present the educational experiences described by autistic people in a paper on pedeutology. The aim of the study was to investigate the opinions on education held by people with autism.
Method. This study employed the netnographic method and involved a group of people with a diagnosis of autism who met online and agreed to participate.
Results. Reaching out to a large group made it possible to analyze their statements by ranking and creating meaning bundles.
Conclusions. The first conclusion is that there is a difference in the approach to the teaching/learning process. This is due to symptoms that are specific to autism, as well as to the different educational and therapeutic approaches. The second conclusion is related to the use of punishment that, in addition to forbidden forms (such as physical punishment), often evolve into psychological and social punishment, such as isolation, marginalization, or a lack of interest. It seems to be equally important to draw attention to the ineffective attempts to impose recognized normative forms of functioning (often referred to as a violation), as well as treating these people as not fully intellectually capable, which is not a condition (intellectual disability can co-occur in a few cases [see Casanova et al., 2000]).

Published: June 2022

Background & objective: Spinal anesthesia (SA) is preferred for fractured femur surgery but it requires proper positioning which is often very difficult to achieve due to pain. Different methods have been used to control the pain during patient positioning, but the results are inconsistent about the superiority of one over the other. We compared femoral nerve block (FNB) and intravenous ketamine for pain control during positioning for SA in elderly patients with femur fracture.
Methodology: A total of 66 patients above 60 y of age were randomly divided into two equal groups; FNB group to receive ultrasound guided FNB with 15-20 ml of bupivacaine 0.25% and ketamine group to receive IV ketamine 0.25 mg/kg. Assessment of VAS scores during positioning before SA was done. Rescue analgesia for pain during positioning was achieved by inj fentanyl IV, and after the surgery by inj morphine IV. Postoperative VAS scores, calculation of total morphine consumption during the first 24 h and any complications were recorded.
Results: The VAS score during positioning was lower in FNB group compared to ketamine group (P < 0.001). This was evident by lower recorded doses of pre-spinal rescue fentanyl. FNB group showed better postoperative analgesia, less morphine consumption and less complications.
Conclusion: FNB provided better analgesia during positioning for spinal blockade in fractured femur patients. Furthermore, FNB was associated with less adverse effects, better postoperative analgesia and less opioid consumption.

Comparison of high dose fentanyl, magnesium and lidocaine for effective and consistent attenuation of hemodynamic responses during laryngoscopy and intubation
Authors: Elsabeeny, MD Walaa Y. , Shehab, MD Nahla N. 
Published: June 2022

Background & objective: Laryngoscopy and endotracheal intubation provoke stress response with consequent hemodynamic instability. Fentanyl is a short acting potent opioid commonly used to control stress response. Magnesium sulphate can attenuate stress response through inhibiting catecholamines release. Systemic administration of lidocaine helps in blocking stress response. This study aimed to compare the effectiveness of high dose fentanyl, magnesium, and lidocaine versus conventional anesthesia on consistent attenuation of stress response to laryngoscopy and endotracheal intubation.
Methods: 160 patients were randomly allocated into one of the 4 study groups. Group C: received fentanyl 2µg/kg, Group F: received fentanyl 4 µg/kg, Group M: received magnesium sulphate 30mg/kg combined with fentanyl 2µg/kg and Group L: received lidocaine 1.5 mg/kg combined with fentanyl 2 µg/kg. Outcome measures included heart rate (HR) values and mean arterial blood pressure (MAP) values during endotracheal intubation and over the following 5 min in addition to coughing and lacrimation during intubation.
Results: HR in group C and group L increased compared to baseline readings following intubation and at 1,3,5 min and was statistically significant for group C but comparable for group L. In group F and group M, HR decreased significantly compared to baseline following intubation and the rest of the times studied. MAP in group C and L were maintained for the period of 5 min following intubation whereas group F and L showed a statistically significant reduction in their MAP values compared to baseline readings.
Conclusion: High dose fentanyl, fentanyl-magnesium combination, and fentanyl- lidocaine combination can attenuate stress response to laryngoscopy and endotracheal intubation when compared to conventional anesthesia. Furthermore, using high dose fentanyl and fentanyl-Magnesium combination results in consistent attenuation of the response.

Authors: Dore Mina Amiri , Torabizadeh Camellia , Keshtkaran Zahra 
Published: June 2022

Background & Objective: Every operating room has been associated with a variety of occupational hazards, but not many studies have been conducted to assess and address these hazards. We used a qualitative approach to explore operating room personnel’s experiences of workplace hazards and how these hazards threaten their occupational safety and health (OSH).
Methodology: This qualitative study was conducted in five teaching hospitals in the south-west of Iran from February 2019 to March 2021. The sample was 24 operating room personnel who were selected under convenient sampling technique. Data were collected using semi-structured, individual interviews, document review and non-participant observation. The collected data were analyzed according to the qualitative content analysis method using MAXQDA v. 2020.
Results: After prolonged analysis of the data, the researchers extracted 644 codes, 13 subcategories, 4 categories, and 1 main theme. The main theme of the study was working in a context of occupational hazards.
Conclusions: Operating rooms are full of potential dangers, which, when combined with the personnel’s negligence and management inefficiencies, increase the risk of occupational health and safety. Therefore, making working conditions safe by providing adequate personal protective equipment (PPE), in-service training, and identifying and managing the causes of personnel negligence are recommended. Moreover, strategies should be introduced to manage stress and conflicts among the healthcare personnel, thus controlling psychological hazards.

Extraction of Copper ion from its water solutions using plant waste (compost), sludge and Bentonite metal as cheap natural adsorbed materials. It was found that Copper ion extraction was based on concentration of Copper and amount of the adsorbed materials. Highest amount of adsorption was obtained at 180 µg Cu ml-1 as Bentonite, plant waste and sludge respectively. Thermal equilibrium of the system was studied by Langmuir equation, R2 gave a good linear relationship in succession. Maximum regulatory capacity and regulatory capacity at equilibrium is 1.0 , 0.99 and 0.96 to plant waste, sludge and Bentonite respectively, as the preference coefficient constant calculated by the Langmuir equation indicate that adsorption is preferable and irriversible for plant waste and sludge while not preferentially and reversible for bentonite. G adsorption reactions were automatic for the Bentonite metal, while for plant waste and sludge non-spontaneous reaction and needs extra activation energy. It is clear from the above that the use of natural materials in the extraction of copper ion is a very effective method and it is an inexpensive and friendly methods envirooment.
Development and validation of comprehensive closed formulas for atmospheric delay and altimetry correction in ground-based GNSS-R
Authors: Nikolaidou Thalia , Santos Marcelo , Williams Simon , Geremia-Nievinski Felipe 
Published: June 2022

<p>Radio wave propagation involved in Global Navigation Satellite System Reflectometry (GNSS-R) is subject to atmospheric refraction. Even for ground-based tracking stations, in applications such as coastal sea-level altimetry, the interferometric or reflection-minus-direct effect might be significant. Although atmospheric propagation delays are best investigated numerically via raytracing, including reflections, such a procedure is not trivial. We have developed simpler closed formulas to account for atmospheric refraction in ground-based GNSS-R, validated against independent raytracing. We provide specific expressions for the linear and angular components of the atmospheric interferometric delay and corresponding altimetry correction components, parameterized in terms of refractivity and bending angle. Assessment results showed excellent agreement for the angular component and good for the linear one. For the conditions analyzed, about half of the delay was found to originate above the receiving antenna, for satellites at low elevation angles. We define the interferometric slant factor used to map interferometric zenithal delays to individual satellites. We also provide an equivalent correction for the effective satellite elevation angle such that the refraction effect is nullified. Lastly, we present the limiting conditions for negligible atmospheric altimetry correction (sub-cm), over domain of satellite elevation angle and station height. For example, for a station five meters above sea level, observations for satellites below 20° elevation angle are subject to more than one centimeter of atmospheric altimetry error.</p>
