Authors: Nasution Fachri Ibrahim , Andasuryani Andasuryani , Putri Renny Eka 
Published: August 2022

Buah salak merupakan suatu hasil pertanian di Indonesia, daerah Kabupaten Tapanuli Selatan menjadi salah satu sentra produksi buah salak terbesar di Sumatera Utara. Penanganan pascapanen buah salak asal Tapanuli Selatan ini atau yang sering disebut buah salak Padang Sidempuan belum dilakukan secara maksimal, sehingga dibutuhkan suatu penanganan buah salak terutama dalam proses grading berdasarkan kualitas buah salak. Penelitian ini memiliki tujuan untuk pengembangan metode image processing buah salak Padang Sidempuan dalam pengelompokan ukuran buah salak menggunakan software Matlab R2015a, serta mengidentifikasi sifat fisik dan kadar air buah salak Padang Sidempuan dari Desa Parsalakan. Proses grading buah salak mengacu pada (SNI 3167, 2009) mengenai bobot buah salak. Hasil yang diperoleh dari penelitian ini adalah program grading model major (Bwarea) dengan tingkat kecocokan 65,0% dengan rata-rata kesalahan pada uji validasi 16,37% dan nilai validasi model yang diperoleh antara bobot buah salak dan Bwarea buah salak Padang Sidempuan dengan nilai R2 0,833. Model intermediate (Bwarea) dengan tingkat kecocokan 78,33% dengan rata-rata kesalahan pada uji validasi 18,45% dan nilai R2 0,882. Model minor (Bwarea) dengan tingkat kecocokan 70,0% dengan rata-rata kesalahan pada uji validasi 12,66% dan nilai R2 0,8879. Model mean (Bwarea) dengan tingkat kecocokan 76,67% dengan rata-rata kesalahan pada uji validasi 8,99% dan nilai R2 0,9528.

Background:
Convexity dural arteriovenous fistulae (dAVF) usually reflux into cortical veins without involving the venous sinuses. Although direct drainage ligation is curative, transarterial embolization (TAE) may be an alternative treatment.

Case Description:
Between September 2018 and January 2021, we encountered four patients with convexity dAVFs. They were three males and one female; their age ranged from 36 to 73 years. The initial symptom was headache (n = 1) or seizure (n = 2); one patient was asymptomatic. In all patients, the feeders were external carotid arteries with drainage into the cortical veins; in two patients, there was pial arterial supply from the middle cerebral artery. All patients were successfully treated by TAE alone using either Onyx or N-butyl cyanoacrylate embolization. Two patients required two sessions. All dAVFs were completely occluded and follow-up MRI or angiograms confirmed no recurrence.

Conclusion:
Our small series suggests that TAE with a liquid embolic material is an appropriate first-line treatment in patients with convexity dAVFs with or without pial arterial supply.
A case of refractory chronic subdural hematoma and internal carotid artery stenosis sequentially treated with surgical drainage, middle meningeal artery embolization, and carotid artery stenting
Authors: Imai Ryotaro , Akiyama Takenori , Mizutani Katsuhiro , Toda Masahiro 
Published: August 2022

Background:
Both chronic subdural hematoma (CSDH) and ischemic cerebrovascular disease are commonplace in the clinical context, and their combination is sometimes experienced. We describe a unique and challenging case in which both therapeutic interventions were indispensable and performed in a sequential manner. This report aims to discuss the management of hemorrhagic and ischemic conditions where CSDH and carotid artery stenosis coexist.

Case Description:
An 83-year-old male presented with the left cerebral infarction due to the left internal carotid artery (ICA) stenosis. The coexisting left CSDH was surgically drained first. Then, the left middle meningeal artery (MMA) was endovascularly embolized to prevent hematoma recurrence under antiplatelet therapy, before the left carotid artery stenting (CAS) was successfully conducted. The subdural hematoma gradually grew but remained asymptomatic. However, he later presented with another stroke due to the progressive right ICA stenosis that had been conservatively treated initially. Emergency right CAS was required eventually.

Conclusion:
Under the circumstances where CSDH is present but antiplatelet therapy is inevitable, MMA embolization could be a reasonable treatment option to avoid additional surgical procedures. Furthermore, early intervention should be considered even for asymptomatic carotid stenosis in terms of shortening the administration period of antiplatelet agents.
Accessory nerve ancient schwannoma: A case report
Authors: Otero-Fernández Paula , Ruiz-Escribano-Menchén Lourdes , Herrera-Montoro Violeta , Morcillo-Carratalá Rafael , Calvo-García Manuel , Llumiguano-Zaruma Carlos 
Published: August 2022

Background:
Lower cranial nerve schwannomas are rare and only 63 cases originating from the accessory nerve have been documented.

Case Description:
We report a 61-year-old man who presented with a 3-month history of dysmetria, ataxic gait, and frequent falls. Magnetic resonance imaging revealed a giant rim-enhancing cystic lesion at the right cerebellomedullary cistern, which markedly displaced the brainstem and caused a critical compression on surrounding structures and mild hydrocephalus. Even though the nature of this lesion was not clear, it received a radiological diagnosis of meningioma as first option. Surgery was performed through an extended far lateral retrosigmoid approach with C1 hemilaminectomy, with intraoperative neurophysiological monitoring. A near-total resection was achieved due to the adhesion of the lesion to the brainstem and to the cranial nerves VII, VIII, IX, X, XI, and XII. Intraoperatively, the tumor was found to arise from the accessory nerve. The histopathological analysis concluded with a final diagnosis of ancient schwannoma, a rare histological subtype characterized by degenerative changes, typical from long-standing tumors.

Conclusion:
Very few cases of intracranial ancient schwannomas have been described. To the best of our knowledge, this is the first report of this extremely rare histological variant arising from the intracisternal component of the XI nerve. The rarity of this disease at this location may lead to preoperative misdiagnosis.

AbstractThis research aims to analyze, design and create a Prisma Stamp ordering information system based on case studies at PT. Pos Indonesia KCU Bandung. Data collection techniques are using observation and interview methods. The software design method used is waterfall. The results of observations made, there are several factors that hamper the sales system of stamps and prisms because they still use manual means using notes and then the sales report is entered into the sales report file that is considered less effective and efficient, therefore, there are often errors at the time of recording transactions. Therefore, in this study created a postage stamp and prism sales system using Unified modeling language and implemented it using codeigniter framework with PHP programming language and MySQL database. The web-based information system is expected to facilitate transactions and expand the prism stamp sales network over the internet and allow administrators to manage product data and view sales reports easily, quickly, and accurately.Keywords: Information System, UML, Web

Published: August 2022

Abstract
In the building industry, it is a frequent cause of damage to elements at different stages: during transportation, operation, installation, etc. Since replacing an element is not always possible due to various circumstances, it entails significant financial losses, logistics, and others. For this reason, the expediency of studying the effect of damage on the bearing capacity of reinforced concrete elements is growing. This effect is dependent on its type and has significant variability. In the case of the combination of the defect and damage in reinforced concrete elements, the complexity of the research of this element increases significantly. In this article is discussed: a review of damaged reinforced concrete elements; researching the influence of the damage and additional factors on the element; developed testing methodology for bending reinforced concrete elements with damage to concrete in a compressed zone with insufficient reinforcement, when performing damage to the action of the load and during the action of the load, is presented; the influence on the deformability and bearing capacity of the variability of damage on the sample with insufficient reinforcement is reflected, taking into account the factor of change in the load at which the damage is performed; a comparison is made of the dependence of the change in the actual height of the compressed zone on the change in the load on the elements; implementation of conclusions on the result of the study.
Experimental studies of the possibility of laser processing as a cleaner method of achieving a surface with good adhesion
Authors: Ciecińska Barbara 
Published: August 2022

Abstract
In manufacturing processes many technological operations are designed, in which the adhesive properties of the treated surface are very important. These are processes related to application of any coating on the surface, such as gluing, painting, varnishing and others. Durability of coatings depends on proper preparation of the surface to which they are going to be applied. Conventional methods, such as grinding, sandblasting with subsequent washing and degreasing, as well as galvanic treatment applied to e.g. aluminium alloys - require the use of not only specific equipment but also chemical substances. They often lead to a significant burden on the environment due to their harmful properties. In an experimental study, attention was drawn to the significant environmental aspects of such a technological process and work was carried out to demonstrate whether it is possible to eliminate toxic and hazardous substances and to create good adhesion conditions by laser processing. To this purpose, samples were made out of two representative materials: X6Cr17 steel and AW-2024 aluminium alloy, abrasive surface treatment or in a galvanic bath and then washed, degreased and dried. Laser surface treatment without the use of additional chemicals was proposed as an environmentally cleaner technology. Surface roughness and adhesion of the test polymer coating were measured for comparative evaluation of the applied treatment methods. Obtained results were discussed in terms of the possibility of eliminating harmful influences and implementing laser treatment as a cleaner technology in the production of components requiring coating.
Антена кругового огляду на основі плазмових випромінювачів

Published: August 2022

В роботі вперше досліджено плоску фазовану антенну решітку, в якій окремим випромінювачем є циліндричний стовп холодної ізотропної плазми, вкритий діелектричною оболонкою. Показано, що випромінювання такої решітки являє собою достатньо вузький промінь при відсутності бічних пелюсток. Коефіцієнт перетворення енергії поверхневої хвилі у випромінювання дорівнює 9% - 15%. Знайдені відстані між окремими випромінювачами, коли взаємодією між хвилеводами можна знехтувати. Розглянуто декілька прикладів бокових граней для різних значень щільності плазми, відстаней між випромінювачами, діелектриками. Для кожного приклада обчислені розміри решітки та ширини діаграм направленості випромінювання. Показано, що при деяких параметрах решітки взаємодія окремих елементів між собою є малою. При цьому зменшується залежність опору випромінювання від кута сканування. Відомо, що ця залежність може призвести до провалів діаграми направленості при деяких кутах. В цих випадках антена “сліпне”. Розглянута ФАР може бути застосована як малопомітна скануюча антена. Показано, що при незмінній загальній кількості випромінювачів форма ФАР слабо впливає на направленість НДН та її ширину. Запропоновано модель антени кругового огляду у вигляді урізаної піраміди. Кожна з граней цієї піраміди є плоскою фазованою антенною решіткою з плазмово діелектричними випромінювачами.

SPEECH ACT PRESENTATION IN A LOCALLY-WRITTEN ENGLISH TEXTBOOK
Authors: Nurdiana Nurdiana Nurdiana 
Published: August 2022

<p><em>A textbook is developed to provide language input for language learners. The input should contain appropriate language use to assist learners to be able to communicate effectively from the communicative competence perspective which focuses on pragmatics. For this reason, the present study attempts to investigate speech act presentation in a local English textbook from metapragmatic, sociopragmatic, and pragmalinguistics point of view. The data were taken from common phrases or language expressions of particular functions integrated with conversations in the textbook. Findings revealed that the the speech acts investigated in the textbook were presented in more discrete items lacking sociopragmatic and pragmalinguistic information. Concerning metapragmatic information, there seems to be a significant correlation between metapragmatic, sociopragmatic, and pragmalinguistic aspects. Pedagogically, it implies that the speech acts exposed through the textbook may not serve communicative functions as it was supposed to be and therefore, the textbook did not contain adequate pragmatic knowledge which may cause fewer opportunities to reach communicative competence. </em></p><p> <strong></strong></p>
