The Relationship Between Obstructive Sleep Apnea And Levels Of Depression And Anxiety In Young Adults
Authors: Yunika Kanti 
Published: July 2022

ABSTRACTBackground: Obstructive sleep apnea (OSA) is one of the most common and serious sleep disorders that can cause various neurocognitive disorders such as depression and anxiety. OSA can occur in young adults, whom are in an important developmental age in human life. The relationship between OSA and levels of depression and anxiety has never been studied in young adults, especially college students. Early identification and treatment is expected to have an impact on better quality of life and productivity..Aim: To determine the relationship of OSA with levels of depression and anxiety in young adultsMethods: An observational study with a cross sectional design. Data were obtained from Berlin questionnaire, Zung Self-Rating Depression Scale and Zung Self-Rating Anxiety Scale which were filled out in September-November 2021. Bivariate analysis of OSA's relationship with depression and OSA with anxiety was tested using chi-square test. Multivariate logistic regression analysis was performed to test for confounding variables.Results: There was a significant relationship between OSA and depression (p=0,000, OR 4.07) and OSA and anxiety (p=0,000, OR 4.5) in young adults. Logistic regression analysis showed that gender was a confounding variable of anxiety (p=0.044) in young adults.Conclusion: There is a significant relationship between OSA and levels of depression and anxiety in young adults. Young adults who have OSA are 4.07 times more likely to be depressed than young adults who don’t have OSA. Young adults who have OSA are 4.5 times more likely to experience anxiety than young adults who don’t have OSA. There is a significant relationship between OSA and the level of anxiety controlled by the confounding variable, namely gender.

Abstract
This work presents a sterile concept for 3D cameras within sterile surgical environments. In the digital operating room (OR), such cameras can serve as a valuable data source for cognitive workflow assistance systems, e.g decision or mechatronic support systems. One recent example are robotic assistants for instrument handling, such as the robotic scrub nurse currently developed in the framework of the SASHA-OR research project1. In this context, we detect laparoscopic instruments and the surgical environment with a 3D camera, whereby hygienic requirements need to be met. Using a Zivid Two sensor, we generated point clouds of the laparoscopic instruments located in an instrument holder and a drop zone. We compared the effect of using different pane types and thicknesses for the sterile camera enclosure and compared the performance with and without protective pane in terms of the point cloud accuracy. When analyzing multiple pane types, polymethyl methacrylate with 0.5 mm thickness (PMMA 0.5) provided the best results. At a scan distance of 560 mm to the surface center, which is required for the complete acquisition of a laparoscopic instrument, PMMA 0.5 achieved the smallest Chamfer distance (CD) values for both the scans with the laparoscopic instruments in the instrument holder (0.23 ± 1.52 mm) and in the drop zone (0.12 ± 0.25 mm).

Warming Up the Cold Call
Authors: Metzger Kelsey J. , Via Zach 
Published: July 2022

Student populations in higher education are more diverse than ever before. Studies of classroom engagement have repeatedly shown that instructors act on implicit biases and that classroom participation is rarely equitable. What can instructors do to support diverse students, specifically with regard to managing classroom engagement and facilitating equitable participation? The practice of cold-calling—calling on a student who has not volunteered to contribute a response—has previously been suggested to support a number of desirable classroom outcomes. However, cold-calling is increasingly recognized to be a potential source of significant student anxiety, particularly for students already experiencing heightened stress due to stereotype threat or other barriers to learning. As such, the solicitation of random and immediate feedback may actually exacerbate inequities rather than ameliorate them as intended.
Here, we introduce a novel classroom participation approach that we call the warm call. This engagement method provides students with an advance warning, and the opportunity to opt out of sharing in front of the class. We describe two different approaches—the “in-class warm call” and the “before-class warm call”—which can be utilized by instructors in any level or size of class to support equitable student participation while also respecting student autonomy.
Interpretation of Oxygen Saturation in Congenital Heart Disease: Fact and Fallacy
Authors: Olsen Jillian , Puri Kriti 
Published: August 2022

Abstract
Oxygen saturation is the percentage of hemoglobin that is saturated with oxygen, converting it to oxyhemoglobin. Oxygen saturation is a critical part of the physical examination of children with congenital heart disease (CHD). The expected oxygen saturation of a patient with CHD depends on their anatomical lesion, their previous surgeries, and any additional pulmonary or systemic pathology that may derange their saturation. Oxygen saturation can be noninvasively measured using pulse oximetry. Pulse oximetry is based on the differential absorption of infrared and red light by oxyhemoglobin and deoxyhemoglobin, with the former absorbing more infrared than the latter. Pulse oximetry readings may be inaccurate in settings of low cardiac output, peripheral vasoconstriction, arrhythmia, hypothermia, and venous pulsations. The use of pulse oximetry in the care of a child with CHD begins with the newborn critical CHD screen. A failed screen indicates a need for further investigation, such as repeated pulse oximetry or echocardiography. The oxyhemoglobin dissociation curve may be used to estimate the partial pressure of oxygen in the blood at various oxygen saturations. It is also a marker of the affinity of hemoglobin for oxygen, with a right-shifted curve indicating a higher oxygen tension needed to saturate hemoglobin. This is a helpful adaptation of the body to situations of stress such as fever, acidosis, and hypercapnia. An understanding of these concepts is paramount for providers caring for patients with known or potential CHD in any setting to appropriately interpret and respond to abnormal saturations for each child.
KEBIJAKAN POLITIK DALAM TAFSIR NEGARA: STUDI ATAS AYAT-AYAT FIQIH DALAM TAFSIR KEMENAG AL-QUR’AN DAN TAFSIRNYA
Authors: Mursyid Achmad Yafik 
Published: July 2022

Penelitian ini membahas tentang corak penafsiran Al-Qur’an sebagai bagian dari kebijakan negara. Negara memiliki agenda untuk menjaga stabilitas sosial-politik dengan mengakomodir dan mengontrol ritual keagamaan masyarakatnya. Hal ini terlihat pada upaya negara dalam menerbitkan tafsir Al-Qur’an contohnya adalah yang diterbitkan oleh Kementerian Agama di Indonesia. Masyarakat Indonesia yang mayoritas mengikuti mazhab Shafi’i menjadi pertimbangan penting bagi negara dalam menerbitkan Tafsir Al-Qur’an, sehingga muncul karya-karya tafsir yang diinisiasi oleh negara melalui Kementerian Agama. Penelitian ini menggunakan pendekatan kualitatif dengan mengumpulkan ayat-ayat Al-Qur’an yang berorientasi hukum pada tafsir Kementerian Agama yang diberi judul Al-Qur’an dan Tafsirnya. Hasil penelitian ini menunjukkan bahwa karya-karya tafsir sebagai bagian dari produk negara memiliki karakter control-oriented. Hal ini terlihat pada karakter mazhab Shafi’i yang menonjol pada tafsir tersebut. Berdasarkan karakter tersebut maka perbedaan latar belakang mazhab cenderung mempengaruhi penafsiran Al-Qur’an dan membentuk ciri khas tersendiri dalam proses penafsiran khususnya pada penafsiran ayat-ayat hukum. Di samping itu, produk tafsir negara juga melahirkan genre baru dalam tradisi tafsir yaitu tafsir kolektif. Tafsir negara juga menunjukan bahwa kesadaran masyarakat Indonesia atas kebutuhan tafsir kontekstual cukup tinggi.

Published: July 2022

Penelitian ini mempunyai dua tujuan yaitu pertama untuk mengetahui bagaimana peran politik Habaib di Kontes Perpolitikan Indonesia dan untuk mengungkap bagaimana kiprah sosial politik Habaib di Indonesia. Metode yang digunakan dalam penelitian ini adalah metode penelitian sejarah dengan tahapan kerja pengumpulan data (heuristik), verifikasi (kritik), penafsiran (interpretasi) dan penulisan (historiografi). Hasil penelitian menunjukkan bahwa meski masih memerlukan pembuktian lebih lanjut, para habaib di Nusantara sudah mulai menunjukkan kiprahnya bukan hanya pada proses islamisasi dan dakwah Islam saja tapi juga masuk ke wilayah politik, pada masa colonial ada bebarapa habaib yang menjadi motor gerakan kemerdekaan bahkan pernah mendirikan Partai Arab Indonesia (PAI). Di masa kemerdekaan keterlibatan mereka dalam bidang sosial dan politik dimulai dari aktivitas di organisasi sosial keagamaan, gerakan-gerakan sosial, mejadi aktivis di partai politik, menjadi anggota parlemen baik di DPD maupun DPR dan terakhir menduduki jabatan politik seperti menteri, atau kepala daerah.
EVOLUTION OF A MULTISCALE SINGULARITY OF THE SOLUTION OF THE BURGERS EQUATION IN THE 4-DIMENSIONAL SPACE–TIME
Authors: Zakharov Sergey V. 
Published: July 2022

The solution of the Cauchy problem for the vector Burgers equation with a small parameter of dissipation \(\varepsilon\) in the \(4\)-dimensional space-time is studied: $$ \mathbf{u}_t + (\mathbf{u}\nabla) \mathbf{u} = \varepsilon \triangle \mathbf{u}, \quad u_{\nu} (\mathbf{x}, -1, \varepsilon) = - x_{\nu} + 4^{-\nu}(\nu + 1) x_{\nu}^{2\nu + 1}, $$ With the help of the Cole–Hopf transform \(\mathbf{u} = - 2 \varepsilon \nabla \ln H,\) the exact solution and its leading asymptotic approximation, depending on six space-time scales, near a singular point are found. A formula for the growth of partial derivatives of the components of the vector field \(\mathbf{u}\) on the time interval from the initial moment to the singular point, called the formula of the gradient catastrophe, is established: $$ \frac{\partial u_{\nu} (0, t, \varepsilon)}{\partial x_{\nu}} = \frac{1}{t} \left[ 1 + O \left( \varepsilon |t|^{- 1 - 1/\nu} \right) \right]\!, \quad \frac{t}{\varepsilon^{\nu /(\nu + 1)} } \to -\infty, \quad t \to -0.$$The asymptotics of the solution far from the singular point, involving a multistep reconstruction of the space-time scales, is also obtained: $$ u_{\nu} (\mathbf{x}, t, \varepsilon) \approx - 2 \left( \frac{t}{\nu + 1} \right)^{1/2\nu} \tanh \left[ \frac{x_{\nu}}{\varepsilon} \left( \frac{t}{\nu + 1} \right)^{1/2\nu} \right]\!, \quad \frac{t}{\varepsilon^{\nu /(\nu + 1)} } \to +\infty. $$
Complex modulus of cement-bitumen treated materials produced with different reclaimed asphalt gradations
Authors: Mignini Chiara , Cardone Fabrizio , Graziani Andrea 
Published: July 2022

AbstractThe increasing attention over cold recycling technologies as sustainable paving solutions requires a proper characterisation in terms of complex modulus for supporting the pavement design. Among cold recycled materials, cement bitumen treated materials (CBTM) benefit from the presence of both bituminous and cementitious binders. This research aims at characterising the complex modulus of CBTM mixtures produced with three different gradations, modified bitumen emulsion and two types of cement. The complex modulus measurements were modelled considering the usual viscous dissipation behaviour, linked to the bituminous component of the mixtures, along with a time- and temperature-independent dissipation component. The results showed that both the aggregate skeleton and the composition of the fine aggregate matrix affected the rheological behaviour. Furthermore, the role played by the aged binder contained in the reclaimed asphalt aggregate was highlighted by the parameters of the rheological model.

Published: July 2022

Culture is the result of the development of human life, and the two things cannot be separated because they are related. The Tabuik culture in Pairaman City, West Sumatra is one of the creations of the development process of human life. Tabuik is a culture that is held every 10th of Muharram, this Tabuik ceremony aims to commemorate the death of the grandson of the Prophet Muhammad S.A.W, namely Hussein bin Ali. This research method is library research with five stages, namely topic selection, source collection, verification, interpretation: analysis and synthesis, then writing. The Tabuik ceremony certainly has a meaning and value that is contained in the ceremony. The meaning of the Tabuik culture itself can be seen from the form of the Tabuik itself, such as the burqa is a symbol of an angel carrying the body of Husein flying, the peak of the tabuik has two meanings, namely as a news carrier and as a protector for all Muslims. The values of the culture are a picture of a combination of custom and religion, so that the values that exist in Tabuik are still not far from religious values.
Kebudayaan adalah hasil dari perkembangan hidup manusia, dan kedua hal itu tidak dapat dipisahkan karena saling berhubungan. Kebudayaan Tabuik yang berada pada Kota Pariaman Sumatera Barat adalah salah satu cipataan dari proses perkembangan hidup manusia. Tabuik ialah kebudayaan yang dilaksanakan setiap tanggal 10 Muharram, upacara Tabuik ini bertujuan untuk memperingati wafatnya cucu Nabi Muhammad S.A.W yaitu Hussein bin Ali. Metode penelitian ini adalah library research dengan lima tahapan yaitu pemilihan topik, pengumpulan sumber, verifikasi, interpretasi: analisis dan sintesis, lalu penulisan. Dalam upacara Tabuik pastinya memiliki sebuah makna dan nilai yang terkandung dalam upacara tersebut. Makna dari kebudayaan Tabuik sendiri dapat dilihat dari bentuk Tabuik itu sendiri seperti burqa adalah simbol dari malaikat yang membawa jasad Husein terbang, puncak tabuik memiliki dua makna yaitu sebagai pembawa berita dan sebagai pelindung bagi seluruh umat islam. Adapun nilai-nilai dari kebudayaan tersebut adalah gambaran perpaduan antara adat dan agama, sehingga nilai-nilai yang ada pada dalam Tabuik masih tidak jauh dalam nilai-nilai agama.

An examination of the links between marital satisfaction, decoding accuracy and conflict
Authors: Soucy Allison 
Published: July 2022

Marital satisfaction plays an important role in maintaining a healthy marriage. One of the major factors affecting satisfaction is communication, thus it is also important to understand the factors involved in communication like non-verbal decoding accuracy and conflict engagement that can affect spouses’ satisfaction with their marriage. The associations between marital satisfaction, non-verbal behaviour decoding accuracy and conflict engagement develop a greater understanding of how these constructs work together to affect satisfaction. This will be examined using a sample of 50 heterosexual couples from the north-eastern states using a longitudinal within-subjects design. We expect dissatisfied couples would be less accurate decoders, leading to increased levels of conflict engagement, and thus lower satisfaction, while satisfied couples would be more accurate decoders, leading to stable levels of conflict engagement, and thus stable or increased satisfaction. The findings from this study will provide important and valuable information, which can be used to improve therapeutic services, like couples counselling.

Authors: Bizuneh Shambel Molla 
Published: July 2022

This study describes deaf and hearing female adolescents’ resilience with their respective counterparts using the Connor–Davidson Resilience Scale. The study was conducted on 160 adolescent [80 deaf (40 females) and 80 hearing (40 females)] students who were randomly selected. Quantitative and qualitative data collections were made through the questionnaire and interviews. The study mainly used descriptive and inferential statistics for data analysis. The results revealed that hearing adolescent students’ average resilience score was significantly greater than deaf students. Female adolescent students’ score level was also found to be significantly lesser than their counterparts. The results further revealed that there was a significant difference in scores among deaf female, deaf male, hearing female and hearing male adolescent students in which deaf female adolescent students’ resilience scores were the lowest. The findings call for health and psychological professionals and families to provide adequate support for deaf and female adolescents to develop resilience.

Published: August 2022

Costa Rica podría generar 1,000,000 m3 de metano diariamente a partir de biogás, pero su aprovechamiento energético requiere del proceso de desulfuración, cuyos materiales filtrantes tienen elevados costos y no se producen localmente. En este estudio se analizaron sustratos naturales locales ricos en óxidos de hierro, suelos arcillosos (SR) y rocas rojas (RR), para la remoción del H2S del biogás. El desempeño de los medios filtrantes se estudió en un sistema de biodigestión anaerobia instalado en una finca porcina cuya producción diaria de biogás es 20-30 m3, 70% metano. Inicialmente se analizaron 6 muestras mediante Difracción de Rayos-X (XRD) y Fluorescencia de Rayos-X (XRF) para cuantificar los óxidos de hierro (Fe2O3) y se seleccionaron las 2 muestras de RR con mayor porcentaje de Fe2O3, RR2 con 4.8% w/w y RR3 con 7.2% w/w. La caracterización de las RR, antes y después de usarlas como medio filtrante, se realizó mediante Microscopia Electrónica de Barrido (SEM), Espectroscopía de Dispersión de Energía de Rayos-X (EDS), y XRD combinado con el método Rietveld (XRD-Rietveld). Tras la aplicación de las RR en el filtro desulfurizador, se comprobó la absorción superficial de azufre y una disminución de 4.8% wt. a 1.1% wt. de los Fe2O3. Las RR con un tamaño de partícula entre 2.4 y 6.3 mm tienen la capacidad de remover hasta un 28% de H2S. La baja eficiencia de remoción de H2S de las RR sugiere la búsqueda de materiales con mayor cantidad de óxidos de hierro para mejorar el proceso de desulfuración.
