Abstract. Volcanic eruptions are among the most jeopardizing natural events due to their potential impacts on life, assets, and the environment. In particular, atmospheric dispersal of volcanic tephra and aerosols during explosive eruptions poses a serious threat to life and has significant consequences for infrastructures and global aviation safety. The volcanic island of Jan Mayen, located in the North Atlantic under trans-continental air traffic routes, is considered the northernmost active volcanic area in the world with at least five eruptive periods recorded during the last 200 years. However, quantitative hazard assessments on the possible consequences for the air traffic of a future ash-forming eruption at Jan Mayen are nonexistent. This study presents the first comprehensive long-term volcanic hazard assessment for the volcanic island of Jan Mayen in terms of ash dispersal and concentration at different flight levels. In order to delve into the characterization and modeling of that potential impact, a probabilistic approach based on merging a large number of numerical simulations is adopted, varying the volcano's eruption source parameters (ESPs) and meteorological scenario. Each ESP value is randomly sampled following a continuous probability density function (PDF) based on the Jan Mayen geological record. Over 20 years of meteorological data is considered in order to explore the natural variability associated with weather conditions and is used to run thousands of simulations of the ash dispersal model FALL3D on a 2 km resolution grid. The simulated scenarios are combined to produce probability maps of airborne ash concentration, arrival time, and persistence of unfavorable conditions at flight levels 50 and 250 (FL050 and FL250). The resulting maps can serve as an aid during the development of civil protection strategies, to decision-makers and aviation stakeholders, in assessing and preventing the potential impact of a future ash-rich eruption at Jan Mayen.

O estudo objetiva identificar perspectivas de professores de Educação Física em relação ao poder que o discurso midiático exerce sobre a formação de opinião do público, considerando os temas “corpo e saúde”; reconhecer suas concepções acerca o papel a ser desempenhado no trato do assunto; identificar espaços dedicados à questão nas aulas da Educação Básica; evidenciar possibilidades e desafios; refletir sobre os achados. Os dados foram produzidos pela Roda de Conversa. Há reconhecimento sobre o poder da mídia, mas não existe abordagem teleológica que a evolva. São reconhecidas poucas possibilidades e muitos desafios. Discussões norteadas por Boaventura de Sousa Santos iluminam alternativas, ficando explícita a urgência de descolonizar subjetividades ligadas a “corpo e saúde”.

Published: January 2022

With climate change resulting from the use of fossil fuel sources and the increasing use of energy, the sources of renewable energy is growing interest in, which includes direct use of the radiation from the sun through photo-voltaic cells. Photovoltaic solar cell covers in Sudan are exposed during the year to many environmental factors such as rainfall and dust accumulation in summer, autumn and winter, which weaken the performance of solar cells, as well as the shades of trees and tall buildings which affect the efficiency of these cells in the morning and afternoon. This paper aims to evaluate the effect of mud on the performance when one use glass and plastic covers for solar photovoltaic cells . Four different covers were installed on the photovoltaic solar cells, namely polycarbonate (PC), polymethylmethacrylate (PMMA), solar glass and ordinary glass for a study to assess their quality for resistance to mud. Experimental work shows that the drop rate of the maximum power and the drop rate of efficiency are 47%, 60%, 49%, and 46% for PC cover, PMMA cover, solar glass cover, and classic glass cover respectively. Thus it is not recommended to use PMMA coating as mud insulation for solar photovoltaic cells.

Allah subḥanah wa taʿalā telah mengabarkan bahwa Al-Qur’an terjaga dari segala kebatilan hingga saat ini dan seterusnya sesuai kehendak Allah, maka senantiasa dibutuhkan bantuan dan arahan dalam memahami Al-Qur’an. Di zaman Nabi ṣallallāh ʿalaih wa sallam beliaulah yang menjelaskan makna-makna Al-Qur’an kepada ummatnya, kemudian dilanjutkan oleh para sahabat raḍiyallāh ʿanhum sehingga orang-orang yang datng kemudian memiliki pemahaman seperti yang diajarkan Nabi ṣallallāh ʿalaih wa sallam. Demikian para ulama’ setalah mereka berpegang teguh dengan tafsir Nabi ṣallallāh ʿalaih wa sallam dan para sahabat beliau raḍiyallāh ʿanhum. Tafsir para ulama’ membantu kita dalam memahami Al-Qur’an agar tidak salah dalam memahami, terlbih lagi di zaman ini yang sudah sangat jauh dari zaman Nabi. Al-Imam Al-Shaukāniyy salah satu ulama’ Islam yang memiliki banyaj tulisan dalam berbagai bidang keilmuan. Diantara karya beliau yang terkenal adalah kitab Fatḥu al-Qadīr yang mengumpulkan antara al-Riwāyah dan al-Dirārayah dari ilmu tafsir. kitab ini mempergunakan metode Taḥlīliyah dan berusaha untuk menggabungkan antara dua jenis analisis al-Tafsīr bi al-Riwāyah dan al-Tafsīr bi al-Dirārayah. Analisis al-Tafsīr bi al-Riwāyah menurut al-Imām al-Shawkāny yaitu penafsiran dengan hadīth Nabi atau athar dari para sahabat, tābi’īn dan tābi’ al-tābīʿīn, yang semuanya itu sampai kepada kita dengan periwayatan sanad para perawi. Sedangkan yang dimaksud dengan al-Tafsīr bi al-Dirāyah atau al-tafsīr bi al-Ra’y yaitu penafsiran dengan akal dengan bantuan ilmu bahasa dan cabang-cabangnya seperti ʿilmu naḥwu, ʿilmu bayān, ilmu ma’āny dan yang lainnya, dan bukan dengan akal dan logika semata.

Authors: Diren Furkan , Boyalı Osman , Savrunlu Eyüp Can , Civelek Erdinç , Kabataş Serdar 
Published: January 2022

Background: It is known that interactions between programmable Ventriculoperitoneal Shunt (VPS) valves and electromagnetic and hearing devices may change the valve settings. We reported a patient using programmable VPS valves and hearing devices and reviewed the literature.
Case Description: A 71-year-old man was implanted with a programmable VPS valve with the diagnosis of Normal Pressure Hydrocephalus. A hearing device (behind-the-ear) was proposed because of hearing difficulties, but it was suggested that it be discontinued because it did not help. However, the patient used it twice because of his current dementia, forgetting the doctor’s recommendations. The setting of the valve has changed in these two different times that this behind-the-ear hearing device is used. Long-term follow-ups showed no change in valve settings except those two situations.
Conclusion: It is important to note that patients using hearing devices and programmable VPS valves are a unique group of patients. There are not enough studies showing the relationship between the behind-the-ear hearing devices and programmable VPS. It should be kept in mind that hearing devices with magnetic field strength may change the setting of the valves.

Published: January 2022

Amaç: Lomber disk hernisi, lomber intervertebral disklerin anulus fibrozlarının yırtılarak nukleus pulpozusun dışarı taşması sonucunda omurilik veya köklerin basıya uğramasıdır. Nüks lomber disk hernisi diskektomi cerrahisi sonrası en az 6 ay süreyle ağrısı geçen hastada aynı seviyede aynı taraf veya karşı tarafta disk herniasyonu gelişmesidir. Günümüzde nüks lomber disk herniasyonlarının görülme sıklığı farklı serilerde %5-15 aralığında bildirilmiştir. Bu çalışmamızda nüks lomber disk hernisi nedeniyle opere edilen olguların ilk operasyon öncesi yapılan radyolojik tetkiklerle ikinci operasyon (nüks) öncesi yapılan radyolojik tetkikleri kıyaslanarak nüks disk hernisi patofizyolojisindeki değişiklikler retrospektif olarak değerlendirildi.
Yöntem: Çalışmamızda retrospektif olarak nüks lomber disk hernisi tanısı ile ikinci kez opere edilen 50 olgunun ilk preoperatif ve ikinci preoperatif radyolojik tetkiklerdeki (lomber direk grafileri ve lomber MRG) değişikliklerin patofizyoloji açısından değerlendirilmesi yapılmıştır.
Bulgular: Çalışmaya alınan 50 hastanın ilk operasyon öncesi ve ikinci operasyon öncesi direkt radyografi ve MRG bulguları karşılaştırıldı. İleri yaş erkek hastalar, geniş tabanlı protrude diski olan, ileri derecede dejenerasyona sahip disk ve faset ekleme sahip hastalarda nüks oranı daha fazla bulundu.
Sonuç: Nüks lomber disk herniasyonu beyin cerrahları ile hastaları karşı karşıya getiren önemli bir sorundur. Preoperatif dönemde bakılacak bazı parametreler ile hastanın nüks oranının daha fazla olduğunu öngörmek ve hastayı bu yönde bilgilendirmek, ilerde oluşabilecek nüks sonrası süreci daha iyi ve olumlu yönetmemizi sağlayacaktır.

Published: January 2022

Introduction:
This study sought to examine prescribing practices for pediatric patients undergoing orthopaedic trauma surgery and assess the effect of state-mandated preoperative informed consent for opioids.

Methods:
A retrospective single-institution cohort study was done between 2016 and 2018 for surgically managed isolated orthopaedic trauma with cohorting based on the presence of preoperative opioid consent. Analyses examined cohort demographic and procedural factors associated with the number of opioid doses prescribed.

Results:
A total of 1,793 patients met the study criteria. The proportion of patients prescribed opioids (P = 0.0378) and the number of doses (P < 0.001) were lower in consented patients. Differences were greater among those receiving solution (versus tablets). No cohort differences were observed in refill needs. Nonopioid medications prescribing increased. Multivariate analysis identified multiple factors, including preoperative opioid consent (P = 0.013) associated with fewer prescribed opioid doses.

Discussion:
After the implementation of preoperative opioid consenting, patients were prescribed fewer opioid doses after pediatric orthopaedic trauma surgery. The increased utilization of nonopioid therapies was also evident. These changes occurred despite a shorter length of hospital stay and without changes in the studied proxies of postoperative pain control. An increased awareness of opioid risks through formal consent discussion may help to facilitate reduced reliance on opioids for children in the postoperative period.
Digital Trade Regulation in the Asia-Pacific: Where Does It Stand? Comparing the RCEP E-commerceChapter with the CPTPP and the JSI
Authors: Oh Eunjung 
Published: January 2022

Over the last two decades, the number of preferential trade agreements (PTAs) including provisions on electronic commerce (e-commerce) or digital trade displayed explosive growth. This phenomenon was especially notable in the Asia-Pacific (APAC), a region that has demonstrated rapid development of e-commerce. This article provides an up-to-date review of the Regional Comprehensive Economic Partnership (RCEP) agreement, focusing on its e-commerce chapter (Chapter 12). By evaluating the change in trends and developments of APAC PTAs covering digital trade, it demonstrates where the RCEP stands. The RCEP E-Commerce chapter is compared to the one in the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), to assess the scope of coverage along with points of convergence and divergence. The article also investigates the World TradeOrganization (WTO)’s Joint Statement Initiative on e-commerce (JSI) and how the provisions in the latest text being negotiated compare to the e-commerce chapters in the RCEP and CPTPP. The article assesses the RCEP’s key implications. Its core value lies on it being an Association of Southeast Asian Nations (ASEAN) - driven negotiation that encompasses the three digital powerhouses of Northeast Asia (China, Japan and South Korea), promoting regional economic integration by bringing together many members who did not have prior common commitments while providing a flexible approach, through variations in schedules and broad exceptions to cater for national sensitivities.
