Authors: Al-metwalli Roshdi R. , Khidr Alaa M. , Fallata Summayah M. , Elsayed Hitham M. A.
Published: March 2022

Background:

Preemptive analgesics are commonly used to increase analgesic efficacy and patient satisfaction. The aim of this study was to evaluate the preemptive analgesic effect of intramuscular diclofenac on minimal effective dose spinal anesthesia for perianal surgeries.

Materials and Methods:

Fifty patients ASA I&II were divided randomly into two groups, control group (GC N = 25) and Diclofenac group (GD N = 25), both groups received saddle block with 5% hyperbaric bupivacaine 0.5 mL (2.5 mg). Thirty minutes before the saddle block, patients in GD received 75 mg (3 mL) diclofenac intramuscularly, whereas patients in GC received 3 mL saline intramuscularly. The differences in the time for the first analgesic request, postoperative analgesic consumption as well as, visual analog scale, were our primary outcomes.

Results:

Fifty patients (25 in each group) undergoing perianal surgery completed the study successfully. The time to the first request of analgesia was significantly longer in GD 511.8 (108.07) min. compared to the GC 179.56 (49.24) min with P = 0.00001, as well as the total consumption of rescue analgesic (tramadol hydrochloride) was significantly less in GD 66 (23.8) mg compared to 104 (28.5) mg in the GC with P = 0.00001.

Conclusion:

Preemptive intramuscular diclofenac sodium with minimal dose bupivacaine saddle block significantly minimized the postoperative analgesic consumption and delayed the first analgesia request after perianal surgery.
Vertebral column length and abdominal girth as predictors for cephalad spread of intrathecal hyperbaric bupivacaine
Authors: Nigam Chanchal , Tyagi Asha , Bhatt Shuchi , Kumar Mahendra
Published: March 2022

Introduction:

In recent literature, there is some suggestion of vertebral column length (VCL) and abdominal girth (AG) in determining cephalad spread of spinal anesthetic. Bodily habitus including abdominal fat distribution, AG, and VCL may vary among individuals from different races/ethnicity. We thus aimed to evaluate the role of AG, and VCL measured with the patient in sitting as well as lateral position, in determining the cephalad spread of intrathecal hyperbaric bupivacaine.

Methods:

Prospective blinded study conducted in 60 consenting adult male patients of ASA status I or II, undergoing lower limb surgery using standardized combined spinal epidural performed. The cephalad spread of subarachnoid block was assessed using loss of discrimination to pin-prick and cold temperature. The VCL was measured from C7 vertebra to the sacral hiatus in sitting as well lateral decubitus position. The AG was measured at level of umbilicus during end of expiration.

Results:

The mean AG and VCL in sitting/lateral positions were: 78.4 ± 11.0, 60.9 ± 3.2, and 59.2 ± 3.2 cm, respectively. VCL in sitting position was significantly longer than in lateral position (P = 0.000). There was no significant correlation between the Smax (pin-prick) and AG (P = 0.138), or VCL in sitting position (P = 0.549), or VCL in lateral position (P = 0.323). Similar lack of correlation was noted with the Smax (cold) as well (P > 0.05).

Conclusions:

Contribution of AG or VCL on the extent of intrathecal drug spread is not a consistent finding.

Published: March 2022

There is limited data and studies that have assessed the co-joint influence of social media applications, social demographic, and individual factors on guests' choice of fine dining restaurants. Previous studies have shown increased use of social media applications by consumers and subsequently influenced decision-making. Thus, need for innovation to meet consumer expectations. A mixed-method approach was used to assess co-joint factors of influence on guests' choice of fine dining restaurants in Kenya. Questionnaires were used to collect quantitative data from purposively selected guests. Data were subsequently analyzed and presented in the form of descriptive and inferential statistics. Testing of the null hypothesis was also conducted. The calculated value of R-squared implies that the remaining variations or determinants in the choice of fine dining restaurants are attributed to factors other than the composite variable. Besides the significant influence of social media applications, there are other factors attributable to guests' selection process. This study contributes to the theory of consumer behaviour in the larger hospitality and tourism industry. The study further reveals new dimensions on the selection of restaurants' products and services. In this direction, managers and owners of restaurants need to embrace more technology in their businesses.
Son Dönem Türk Sinemasında Anti-Kahraman Kadınlar
Authors: KİRAZ DEMİR Selin
Published: March 2022

Türk sinemasının karakter temsilleri bağlamında yapısal dönüşümü düşünüldüğünde özellikle 80’ler sonrasında o güne dek tabu olarak kabul edilen eşcinsellik, etnik kimlikler ve inanç meselesi gibi birçok konunun beyaz perdeye taşındığı görülmektedir. Buna rağmen, günümüzde dahi Türk filmlerinin temalarında tam anlamıyla toplumsal cinsiyet kalıp yargılarının aşıldığı söylenemez. Genellikle ideolojik yaklaşımlar çerçevesinde şekillenen ve toplumsal yaşamda yazılı olmayan bir kural gibi işleyen bu roller, sinemada da karakterler aracılığıyla kendisini gösterir. Fakat bugün, toplumsal cinsiyet kalıplarının dışına çıkıyor olsa da izleyici tarafından benimsenen farklı bir karakter yapısı bulunmaktadır: Anti-kahramanlar. Çalışmada, Türk sinemasının son dönemde çekilen Nefesim Kesilene Kadar (2015) ve Sofra Sırları (2017) adlı filmleri üzerinden anti-kahraman kadın karakterler feminist kuram çerçevesinde betimsel analiz yöntemiyle incelenmiştir. Çalışmada, kadın karakterlerin filmlerdeki temsil biçimlerine odaklanılmaktadır. Dolayısıyla, her iki film de Türk sinemasında başrollerde yer alan anti-kahraman kadınların temsilini kadın ve erkek yönetmenlerin bakış açısıyla yansıtmasından dolayı çalışmaya dahil edilmiştir. Çalışmada, anti-kahraman kadınların sinemada toplumsal cinsiyet rollerinin sunulmasına ve karakter oluşumuna olan etkileri sorgulanmıştır. Buna göre, kadın karakterlerin anti-kahraman olarak konumlanması ile birlikte toplumsal cinsiyet kalıp yargılarını dönüştürme potansiyeli olduğu saptanmıştır.
Big History－General Education for the Anthropocene
Authors: Kim Gi-Bong
Published: March 2022

What is general education? This question usually presumes that general education exists as a substance. Following this presumption, “artes liberalis” and “Bildung” are considered as the archetypes of general education. These two have different meanings, but they both set human beings as the subject and they both teach humanities and living arts. The Anthropocene, which threatens the survival of mankind, let alone the sustainability of human civilization, demands a new concept of general education that breaks away from anthropocentrism. The conventional Humanities-centered general education must break out of the egg of humanism. Big History, which provides scientific knowledge on almost everything from the Big Bang to the Anthropocene, can present a post-human general education concept and a general education model. Therefore, this thesis aims to find a way for a general education Renaissance in the Anthropocene through Big History.
A Study on a Teaching & Learning Method for Basic and General Education in the Post-Corona－Focusing on the Blended Learning
Authors: Shin Jong Ho , Song Ha Suk
Published: March 2022

Considering the number of non-face-to-face classes occurring in the Covid-19 era, it is now widely recognized that blended learning will become the new normal for education in the post-Corona era. However, detailed discussions have not sufficiently taken place as to why blended learning is necessary in the post-Corona era, nor how this type of learning should be applied and practiced. Therefore, this paper discusses the necessity of applying blended learning as a teaching and learning method for basic and general education in the post-Corona era. It also examines the methods and requirements for effectively implementing blended learning for these future classes. As blended learning enables ‘'student-centered teaching’ or ‘active learning’in order to develop the various competencies without excluding knowledge education, it is suitable for basic and general education that aims to strengthen competencies as well as to acquire knowledge. As a method for practicing blended learning for basic liberal arts education, first, we suggest that it is necessary to develop standardized video-lectures for the uniformity of the students' learning experience and for the improvement of learning effectiveness, as well as the development of modular content in the form of micro-learning. Second, considering the characteristics of basic and general education subjects and and the learners themselves, it is suggested that we customize teaching-learning methods for each student level using learning analytics and artificial intelligence. Third, we emphasize that it is necessary to develop an educational model for blended learning for each subject and to strengthen the competencies of professors in order to effectively operate blended learning classes in basic and general education. Fourth, we suggest that an organization-oriented curriculum redesign project be implemented to change the educational method to blended learning and to spread it on a large scale at the university level.
A Teaching Methods of Structural Mapping as a Visualization Process of Summary Thinking
Authors: Kim Nammee
Published: March 2022

The purpose of this thesis is to propose a method of teaching abstract thinking through structural drawing that visualizes the macro structure in a liberal arts writing class at a university. First, by analyzing the results of the learner’s structure diagram from 2018 to 2021, we calculated notable issues for summary thinking training, and based on this, we proposed a practical class plan. First, it was important to clearly maintain the distance between the learner, who is the subject of the text summary, and the original author of the text. This is an important principle for accurately understanding the text and also for understanding the learners themselves, who again are the subjects of the summary. Second, it was important to adjust the level of abstraction and generalization of text information. This abstraction generalization process is a process of considering abstract thinking and the relationship between texts by reflecting the key elements constituting the text in the structural diagram. Third, it was important to understand the text composition principle through the activity to check the hierarchy among the core information constituting the text. Some examples of possible classes to help us achieve the main goal for this summary thinking were introduced. First, we presented the process of internalizing the thinking process involved in abstract thinking through multi-faceted feedback activities on the structural diagram using abstract thinking. Second, in order to strengthen the process of understanding the internal relationship of the text structure, a method for internalizing the concept and thought process used in actual thinking was suggested by comparatively analyzing the meta-activities identified in the previous feedback process. Finally, a method to strengthen the openness of summary thinking was suggested by imparting that the structure drawing activity itself has an open possibility.

Authors: Paul Arindam , Behera Jayanti , Sahoo Dukhabandhu
Published: March 2022

This paper examines the asymmetric impacts of renewable energy intensity (REI) and non-renewable energy intensity (NREI) on total factor productivity (TFP) growth in 17 Asia-Pacific countries during 1990–2018. The results reveal that REI positively impacts TFP growth in the long run, while NREI harms TFP growth in the short run. However, the study finds NREI has an asymmetric impact on TFP growth. This study suggests intensifying renewable energy usage in the production process to achieve sustainable growth.

Conexões entre a Boca do Mato e a Cidade Macuti: territorialização, discurso higienista e marginalização
Authors: Augusto de Mattos Regiane , Costa Araújo Luis Gustavo , Ali Aiúba Aiúba
Published: March 2022

Partindo de um passado conectado por experiências sociais compartilhadas de colonização e escravização na América Latina e em Moçambique, o artigo tem por objetivo refletir sobre processos históricos enfrentados por duas comunidades especificamente – a Boca do Mato no Rio de Janeiro e a Cidade Macuti, na Ilha de Moçambique. Destacamos os aspectos comuns que dizem respeito à ocupação desses espaços desde o início do século XIX por escravizados fugidos ou libertos, conhecidas como quilombos (Serra dos Pretos Forros) ou mussitos (Ilha de Moçambique), e que são fruto do processo de territorialização, percebido também em outras partes da América Latina, como os cumbes, na Venezuela e os palanques, na Colômbia; bem como a arquitetura das moradias que remontam às técnicas africanas com o uso da terra, madeira e cobertura com fibras vegetais. Quanto às representações sobre as populações e suas manifestações culturais analisamos alguns casos de perseguição e depreciação das práticas religiosas e culturais, como os cultos de matriz africana e os chamados batuques, resultado da produção de imaginários culturais ligados também ao processo de territorialização colonial. O segundo eixo apresenta uma reflexão sobre um processo marcado por ações sanitaristas e por discursos higienistas diante das epidemias que assolaram esses espaços entre meados do século XIX e o início do XX, e que foram atrelados a projetos “modernizadores” das cidades. Analisamos nessa seção como a febre amarela no Rio de Janeiro e a peste bubônica na Ilha de Moçambique, bem como as políticas de saúde pública atreladas a uma ideologia racial, impactaram as populações da Boca do Mato e da Cidade Macuti. Quanto ao restante da América Latina, uma conexão possível é feita com alastramento da chamada "febre do temperamento", do Brasil em direção a Montevidéu e Buenos Aires, em meados da década de 1850. Ambos resultaram na marginalização racial e na exclusão social de indivíduos negro-africanos habitantes dessas comunidades.

To do this, we use science and evidence to tackle the challenges of today, to identify and address emerging risks, and to ensure the UK food safety regulation framework is modern, agile and represents consumer interests. One way we build our understanding of consumer interests and concerns is through social media analysis, which permits real time monitoring of key issues relating to food safety and other consumer concerns.
Organizational and economic mechanism of strategic management of sustainability of supply chains of industrial enterprises
Authors: Hryhorak Mariia , Trushkina Nataliia , Kitrish Kateryna
Published: March 2022

The article deepens the theoretical and methodological foundations of the organization of strategic management of industrial enterprises` supply chains sustainability. The evolution of the concept of supply chain management is considered from the standpoint of the institutional theory, as well as the influencing of various factors on its development and integration with the concept of sustainable development is determined. The conceptual and categorical apparatus for researching supply chain sustainability management from the standpoint of network theory and stakeholder theory has been developed. On the example of a metallurgical enterprise, a system of indicators of sustainable development is proposed and strategic guidelines for three scenarios of sustainable development of an enterprise are determined. These three scenarios take into account the conditions for future development, which are defined as pessimistic, optimistic and such as to ensure balanced sustainable development. Calculations of strategic scenarios for sustainable development were based on the determination of threshold values of indicators for three components: economic (including the quality of corporate governance), environmental and social. Strategic benchmarks have been developed for each of the scenarios. In the course of the study, it was found that it is inappropriate to calculate the integral sustainability index for the entire supply chain as a whole. Such a calculation has no informative value and is technically practically impossible due to the incomparability of indicators of different business units included in the supply chain. A conclusion is drawn from this that the sustainability of each individual business unit in the chain should be assessed separately. An organizational and economic mechanism for managing the sustainability of the supply chain in a hybrid form is proposed, which provides for a combination of decentralized development of sustainable development strategies by individual enterprises and organizations within the supply chain and centralized coordination and monitoring of the implementation of strategies by a focal company based on a digital platform. The concept of this mechanism is based on a network approach and provides for the organization of collaboration of participants in the supply chain with the involvement of a wide range of stakeholders. The directions in which various digital technologies can be applied in managing the sustainability of the supply chain are considered, among which blockchain technology is recognized as the most suitable for use at the moment.
Modelling of a Conventional Piston of a Single Cylinder Four-Stroke Diesel Engine by Using SolidWorks
Authors: Isaac Festus O. , Abu Lukman
Published: March 2022

This paper presents a 3D modelling of a conventional piston of a single cylinder four-stroke diesel engine using ZS1115NM diesel engine specification. Piston in internal combustion engine (ICE) is a circular piece of metal which converts the rotary movement of the crankshaft into reciprocating motion thereby exerting a force on the air-fuel mixture in the cylinder. It converts thermal energy into mechanical energy in an internal combustion engine (ICE). The methodology applied was analytical design and modelling of the piston using SOLIDWORKS 2013 3D Computer Aided Design (CAD) software. This method was used because it provided a step by step designing of the various elements of the piston. The material chosen for the piston is an aluminium alloy designated as A92618 or simply A2618, due majorly to its high coefficient of thermal expansion (CTE) which enables the piston withstand high thermal stress without cracking or failure. Another important reason is that it has a high thermal conductivity (approximately 3 times than that of cast iron). It is seen that with given engine specification a suitable material for designing a conventional piston is chosen and the model manufactured. Keywords— 3D modelling, ZS1115NM, Internal combustion engine, SOLIDWORKS 2013, A2618, Coefficient of thermal expansion

Hydrocarbon production accompanied by the flow of sand from reservoirs is unavoidable as many of the formations are poorly consolidated. The deposition of the produced sand at low velocities or production of sand at very high velocity can pose serious challenges to the condition of the petroleum pipeline as it can lead to pipeline capacity reduction and degradation respectively. It is therefore important to investigate the minimum transport velocity that prevents sand deposition in the pipelines. In this study, the firefly optimization algorithm (FFA) was used in the development of the improved model for the prediction of minimum transport condition (MTC) in a multiphase pipeline. The model development was implemented using the MATLAB software package. The input parameters were sand concentration, particle diameter, viscosity, density and superficial velocity of the hydrocarbons. The developed model was observed to perform better than the base model with a R2 value of 0.9845 and 0.8149 for the developed model and base model respectively.  The newly developed model was also compared with some existing models and the statistical measures show that the developed model gave a better performance. This enhanced model can be used for the prediction of MTC in multiphase pipelinesKeywords— Algorithms, Artificial Neural Network (ANN), Firefly algorithm (FFA), Minimum Transport Condition (MTC)

Authors: Olarinoye Gbenga A. , Akorede Mudathir F. , Akinropo Charles D.
Published: March 2022

Three-phase Induction motors are increasingly used in a variety of applications such as fans, milling machines, transportation, etc. In applications requiring precise speed control such as robotics, centrifugal pumps, mills and other high-performance applications, it is essential that speed is maintained constant at a desired fixed value.  Many speed control techniques exist in literature but this paper presents the design of a simple PI controller and its use to control the speed of a three-phase induction motor. A controller design that applies the Phase margin (PM) as the stability criterion is employed. The cross-over frequency and phase margin of the open loop gain of motor and controller are specified in order to develop a stable control system. The three-phase induction motor model is presented and modified for the purpose of control. A comparative analysis between the motor performance with and without the PI controller was performed. The unit step response of the speed control loop is characterized by rise time, settling time, steady state error and peak overshoot of 0.0253s, 0.19s, 2.2e-14% and 24.03% respectively. Simulation results show that the speed of the uncontrolled motor changed whereas that of the controlled motor returned quickly to its initial value after the motor is subjected to load disturbances in steady state.Keywords— Controller, Induction motor, Model, Speed control, Steady state.

Milk is a rich nutrient white liquid food produced by the mammary gland of mammals vulnerable to bacteria that cause diseases to the human health. In a dairy plant, pasteurization process is the best heating procedure for a milk. It can be performed under High Temperature Short Time (HTST) or Low Temperature Long Time (LTLT). However, optimal temperature stability control has been a major challenge for milk pasteurization in a dairy plant due to non-linearity, time delay schemes, inaccuracy and unrealistic parameter variation of the modern and manual tuning techniques used without incorporate a numerous adaptive tuning control method. Therefore, this article proposed an optimization tuning technique of Extremum Seeking (ES) based Proportional Integral Derivative (PID) controller to optimize the heating process and eliminate the external perturbation of the system. In this article, a closed loop mathematical equation model using ES-PID controller was developed proposed to achieve the optimal performance characteristics. The due technique is expected to eliminate the offset of the system and minimize the percentage overshoot.Keywords- Milk Pasteurization, Temperature Control, Extremum Seeking, Proportional Integral Derivative.

Corrosion detection using advanced equipment could be sometimes unavailable in resource-limited settings. To make up for the corrosion testing gap, image capturing and processing with Convolutional Neural Networks (CNN) have gained prominence in corrosion studies. In this study, two CNN models were built and trained using images taken with a mobile phone camera and a digital microscope. The CNN models were built to categorize corroded images into three different classes based on the surface area of the sample that were covered by the corrosion products. The study shows that CNN corrosion classifiers perform very well with accuracy above 80% for both models. The use of CNN was found to be effective for multiclass corrosion.Keywords— Corrosion, Convolutional neural network, Corrosion detection, Image processing.

Javanese language is one of the lessons that students consider the most boring, especially for students at the level of Madrasah Ibtidaiyah or Elementary Schools. The teaching method of the teacher still uses conventional methods, namely the teacher explains with lectures and students listen to textbooks. The media used are limited to textbooks and white boards. Given the importance of these subjects, a new alternative is needed to support learning media for optimal learning. Although the learning media used currently exist, they are not optimal. So that development needs to be done in order to create more effective learning media. The methodology used is structured analysis and development, starting from analyzing the running system to the proposed system using UML. The final result achieved from this writing is the formation of a system procedure using UML. In addition, an android-based interactive learning media application design using APP Inventor was also produced. The formation of this interactive learning media application design is expected to optimize learning Javanese language subjects about word processing for Madrasah Ibtidaiyah students to support student learning at home and in the classroom.

Published: March 2022

The primary objective of this research is to investigate the major advantages of stem cell dental implants alongside their role in tooth regeneration and their potential to replace the already existing dental implant method. Dental implants are considered the latest teeth replacement technology in the 20th century. Despite its obvious purpose, the treatments are still uncommon due to their extensive healing process and other potential risks regarding infections. On the account of these concerns, scientists are looking into new possibilities of teeth replacement treatment and therapy. Stem cell therapy is commonly used for treating diseases by replacing tissues that are damaged due to injuries or diseases. Stem cells are unspecialized cells and are capable of diving and regrowing themselves. Due to these properties, stem cell dental implants are now considered to be a new alternative to teeth implants.

Authors: Supraptomo RTH
Published: March 2022

Seksio sesarea adalah sebuah prosedur dimana bayi dilahirkan melalui sebuah insisi pada dinding abdomen dan uterus ibu hamil. Selama persiapan dan pelaksanaan seksio sesarea, pada ibu hamil dengan asma, dapat terjadi serangan asma, yaitu hiperresponsif jalan nafas (respon penyempitan dan edema jalan napas yang berlebihan terhadap pemicu, seperti alergen dan olahraga), dengan gejala mengi, dispnea (sesak napas), dan batuk. Serangan asma ini dapat diakibatkan pelepasan epitel, fibrosis subepitel, peningkatan jumlah dan volume sel mukosa di epitel, hiperplasia otot polos jalan napas, dan hipertrofi, serta peningkatan vaskularisasi dinding jalan napas. Manajemen serangan asma pada seksio sesarea dipengaruhi oleh teknik anestesi yang digunakan. Manajemen serangan asma pada seksio sesarea dengan anestesi regional, dapat menggunakan lidokain 1-2 mg/kgBB IV. Serangan asma pada seksio sesarea dengan anestesi umum dapat dicegah dengan kortikosteroid inhalasi seperti beclomethason 400 μg per hari. Perawatan harus diambil untuk mencegah aspirasi selama intubasi. Jika mungkin, pasien harus ditempatkan dengan kepala tempat tidur ditinggikan untuk mencegah pneumonia terkait aspirasi dan eksaserbasi asma

Perlemakan hati akut pada kehamilan (acute fatty liver of pregnancy = AFLP) merupakan kasus yang jarang terjadi, tetapi dapat mengalami komplikasi yang mematikan. Hal tersebut dapat terjadi pada trimester ketiga kehamilan atau awal pasca persalinan. Insiden AFLP berkisar dari 1: 1,000 sampai 1: 20,000. Angka kematian ibu dengan AFLP rata-rata 12%. Kematian berkurang sampai dibawah 10% dengan terapi yang tepat. AFLP ditandai oleh penyusupan (infiltrasi) lemak mikrovesikuler sel hati (hepatosit) tanpa peradangan atau kematian jaringan (nekrosis). Penyebab penyakit AFLP secara tepat masih belum diketahui, diduga kekurangan mitochondrial trifunctional protein (MTP) dan long-chain 3-hydroxyacyl-coenzyme A dehydrogenase (LCHAD) mengakibatkan penumpukan asam lemak rantai sedang dan rantai panjang di hati. Kekurangan LCHAD merupakan kelainan otosom yang muncul (resesif) dan sering terjadi pada ibu memiliki kelainan gen heterozigot dengan janin homozigot, sehingga mengakibatkan kelebihan metabolit toksik. Seorang wanita 33 tahun G1P0A0 datang hamil 32 minggu dengan diagnosis AFLP mempunyai keluhan: nyeri kepala, lemah, mual dan muntah. Hasil laboratorium terjadi hiperbilirubinemia, hipoglikemia, dan gangguan koagulasi. Dilakukan seksio sesarea dengan anestesi umum. Intubasi dilakukan dengan rapid sequence induction dan setelah pipa endotrakheal masuk dijaga tanda vital supaya tetap stabil. Pasca operasi pasien masuk intensive care unit untuk pemantauan lebih lanjut. Kunci untuk bertahan hidup adalah diagnosis dini, persalinan segera, pengobatan segera hipoglikemia dan koagulopati, dan pencegahan komplikasi gagal hati.

Angka Kematian Ibu (AKI) di Indonesia tinggi dengan hipertensi pada kehamilan dan penyakit jantung sebagai salah satu penyebab utama. Sebagian besar pasien dengan preeklamsia dan gagal jantung menjalani operasi seksio sesarea dan memerlukan manajemen anestesi dengan mempertimbangkan luaran maternal dan janin. Wanita berusia 30 tahun dengan G2P1A0 gravida 32–33 minggu dengan hipertensi kronis diperberat preeklamsia induced Acute Decompensated Heart Failure (ADHF), sindrom Hemolysis Elevated Liver Enzyme Low Platelet (HELLP) dan gagal jantung kelas II-III dengan status fisik ASA IIIE. Dilakukan manajemen anestesi regional epidural dengan tujuan utama mempertahankan hemodinamik ibu. Hemodinamika selama durante operasi stabil. Dilahirkan bayi laki-laki hidup dengan APGAR 6–8. Pasien ditransfer ke High Care Unit (HCU) pascaoperasi. Manajemen anestesi perioperatif pada pasien harus menghindari perubahan hemodinamik yang ekstrem, menjaga aliran darah uteroplasental dan luaran bayi, dan menghindari risiko sulit intubasi dan aspirasi pada ibu hamil. Pada pasien ini dipilih manajemen anestesi epidural dengan monitoring hemodinamik ketat selama durante operasi. Pada pascaoperasi, pasien dirawat di ruang High Care Unit dan diberikan analgetik multimodal untuk menghindari lonjakan hemodinamik akibat nyeri. Pasien pulang ke rumah pada hari ke-5 pascaoperasi. Anestesi regional epidural merupakan pilihan yang dapat digunakan pada pasien preeklamsia berat dengan ADHF dan sindrom HELLP dengan mempertimbangkan keuntungan terhadap luaran maternal dan fetal

Authors: Jaas Allam
Published: March 2022

This article seeks to examine the role of the Islamic economy and finance in combating the phenomena of poverty and unemployment in Muslim countries. It also proposes mechanisms to address the problem of unemployment through Islamic banks with the aim of achieving economic development and social solidarity, as well as through the alms (Zakat) fund by establishing special funds to finance investment projects needed by the unemployed. Moreover, it studies the crisis of unemployment, as the article shows the role of waqf (which is an Islamic endowment of property to be held in trust and used for a charitable or religious purpose) as an economic institution that can provide jobs for its performers, and provide jobs through projects. The study also shows how the Islamic economy can address the problem of poverty (through zakat and waqf), by giving good loans, to finance small projects, as well as by providing social and economic services to the poor and needy.

Pada era modernisasi, terdapat banyak hal yang mengalami perkembangan di berbagai bidang. Misalnya di bidang bisnis, kini sudah mengenal sistem online, dimana pembeli dan penjual tidak perlu tatap muka untuk melakukan transaksi jual beli. Terlebih lagi pada masa pandemi Covid-19 yang membatasi sejumlah kegiatan mengakibatkan belanja online mendapat banyak perhatian. Tidak hanya produk pabrik, bahkan produk rumahan juga ikut terseret arus belanja online. Bahkan saat ini sudah terdapat berbagai macam metode pembayaran, baik itu melalui transfer rekening, melalui layanan aplikasi, bahkan ada beberapa toko yang mengantarkan produk mereka langsung ke tangan konsumen, yang kemudian dikenal dengan istilah COD. Metode pembayaran COD sendiri memiliki kelebihan dan kekurangan. Salah satu kekurangan COD adalah modal untuk melakukan transaksi bisa saja jauh lebih besar ketimbang pendapatan. Faktor yang mempengaruhi hal ini bisa jadi karena faktor kondisi jalanan, faktor cuaca dan faktor pemborosan bahan bakar kendaraan. Oleh sebab itu penelitian ini dilakukan untuk membantu para petugas COD mencari rute terpendek untuk penghematan biaya, yang akan direpresentasikan dengan graf menggunakan algoritma Floyd Warshall.

Persimpangan Jalan Kolonel Yos Sudarso merupakan salah satu persimpangan yang sering mengalami masalah kemacetan dikarenakan durasi nyala lampu hijau lebih sedikit dibandingkan dengan nyala lampu merah sehingga waktu tunggu bagi kendaraan belum optimal. Tujuan penelitian ini diharapkan mampu mengatasi kemacetan lalu lintas dengan pemodelan graf kompatibel menggunakan metode Webster. Pemodelan graf kompatibel digunakan untuk mengetahui fase lampu lalu lintas dan arus yang dapat berjalan dengan bersesuaian sedangkan metode Webster digunakan untuk mengetahui keoptimalan waktu tunggu bagi kendaraan di persimpangan. Hasil penelitian yang diperoleh adalah terdapat 3 fase lampu lalu lintas yang dioptimalkan. Pengoptimalan waktu tunggu total di persimpangan dengan menggunakan metode Webster menghasilkan siklus waktu yang optimum yaitu untuk setiap fase mendapatkan waktu 220 detik. Hasil dari metode ini dikatakan efektif karena tiap kaki simpang yang bervolume tinggi dengan lebar jalan yang lebih kecil terdapat penambahan dan pengurangan durasi nyala lampu lalu lintas.
