A Deep Attention-based U-Net for Airways Segmentation in Computed
Tomography Images
Authors: Khanna Anita , Londhe Narendra Digambar , Gupta Shubhrata 
Published: July 2022

Background:
Airway segmentation is a way to quantify the diagnosis of pulmonary diseases,
including chronic obstructive problems and bronchiectasis. Manual analysis by radiologists is a
challenging task due to the complex airway structure. Additionally, tree-like patterns, varied shapes,
sizes, and intensity make the manual airway segmentation task more complex. Deeper airways are
even more difficult to segment as their intensity starts matching the lung parenchyma as the diameter
of the airway cross-section gets reduced.

Objective:
Many earlier works have proposed different deep learning networks for airway segmentation
but were unable to achieve the desired performance; hence the task of airway segmentation still
possesses challenges in this field.

Method:
This work proposes a convolutional neural network based on deep U-Net architecture and
employs an attention block technique for airway segmentation. The attention mechanism aids in the
extraction of the complicated and multi-sized airways found in the lung region, hence increasing the
efficiency of the U-Net architecture.

Results:
The model has been validated using VESSEL12 and EXACT09 datasets, individually and
combined, with and without trachea images. The best DSC scores on EXACT09 and VESSEL12 datasets
are 95.21% and 95.80%, respectively. The performance on both datasets combined gave a DSC
score of 94.1%, showing that the overall performance of the proposed methodology is quite satisfactory.
The generalizability of the model is also confirmed using k-fold cross-validation. The comparison
of the proposed model to existing research on airway segmentation found competitive results.

Conclusion:
The use of an attention unit in the proposed model highlights the relevant information and
reduces the irrelevant features, which helps to improve the performance and saves time.

Industry
Authors: Gujar Jotiram G. , Patil Sanjay S. , Sonawane Shriram S. 
Published: July 2022

Abstract:
Nanofluids are a new class of nanomaterials suspended in a base liquid. Nanofluids have shown extremely distinctive properties that give tremendous opportunities for a wide range of applications. Nanofluids are a novel group of heat transfer fluids that have attracted the attention of researchers from various fields due to their intensive thermal properties. This systematic review highlights the synthesis, stability, physical treatment, and applications of nanofluids in various sectors. Applications of nanofluids in different sectors like the coolant in machinery, cooling of electronics, in chillers, cooling of diesel electronics generators, in a boiler cool gas reductions, and the manufacturing industry. The manufacturing process is one of the most fundamental and well-proven industrial processes in product-based industries. Cutting fluids play a critical function in lowering manufacturing cycle time as well as cutting costs during the machining process. A review of the importance of the machining process, as well as the use of nanofluids as cutting fluids, has been investigated in this work. To achieve these goals, cutting force, surface quality, tool and workpiece interface temperature, tool geometry, and the impacts of environmental situations were studied. Various vital specifications, such as the type of nanoparticle, a cutting tool used, work material type, and machining processes like turning, milling, drilling, and grinding were studied and thoroughly summarised in this work. If the machining parameters were used correctly, a greater heat transfer rate would be observed due to changes in lubricating characteristics and physical parameters.

Published: July 2022

Introduction:
There have been 214 million confirmed cases of COVID-19 worldwide with a total death tally of 4.4 million. The current study aims to determine the predictive value of various scores in assessment of progression of mild COVID-19 infection at a tertiary care hospital in North India.

Methods:
The study population consisted of adults (age more than 18 years) with a confirmed diagnosis of COVID-19 by RT-PCR on nasopharyngeal specimens. Patients with only mild illness were enrolled. After the patients were admitted to the isolation ward, the presenting history, comorbidity status, vital signs and laboratory parameters were recorded. The 3 and 6 minute walk test was performed daily from admission till discharge or progression of severity of COVID-19 and it was used to calculate Borg dyspnoea score (BDS) and National Early Warning Score (NEWS2) scores.

Results:
Our study consisted of 50 patients with 34 (68%) males and the mean (SD) age of the patient population being 28.1 (6.4) years. The most common symptoms were fever, sore throat, and cough. All laboratory parameters were within normal ranges for all the patients. 96% recovered without progression, while only 4% of them progressed to moderate illness. Results of the 3 and 6 minutes walk tests, BDS and NEWS2 scores showed improvement over the course of hospital stay.

Conclusions:
Although the walk tests and the scores improved over time, they failed to predict the disease progression.

Authors: Astuti Endang Pudji , Nurmalina Rita , Rifin Amzul 
Published: July 2022

Membership in the G-20 forum is both a threat and an opportunity for Indonesian agricultural commodities. Indonesia must be able to take advantage of this great opportunity to increase international trade activities, especially exports. Although the G-20 market is a potential market, Indonesia faces challenges because it is considered not ready to compete and threatened to become a market for other countries. In 2020, Indonesia's agricultural exports (HS 01-24) are in ninth place compared to its competitors in G-20 market. In order to increase the export share, the purpose of this study is to analyze the development of exports from Indonesia to the G20 market and the competitiveness of agricultural products. The analyzes used are descriptive analysis, Revealed Comparative Advantage (RCA), and Dynamic Revealed Comparative Advantage (DRCA). The results showed that 63.25% of the five selected agricultural export commodities had comparative competitiveness in the G-20 market. From the trend of increasing exports, several countries that become non-traditional markets have the potential as a market diversification destination, including Saudi Arabia, Mexico, Turkey, and Argentina. DRCA analysis shows that the dynamics of the G-20 market are quite large, and some of them are experiencing a decline. The strategy to increase exports to the G-20 market is to maintain the competitiveness of commodities in the rising star quadrant, as well as increase the competitiveness of commodities that are in the lagging opportunity and lost opportunity quadrant due to high global demand for these commodities.

NDVI analysis was calculated based on the ratio of the reflection of red and near infrared waves. Aims of this study is to determine the density condition and health level of oil palm plants that have entered the age of replanting using the NDVI index from Landsat 8 satellite imagery and evaluate the plant health level based on the NDVI index compared with the LSU data. The research was conducted at Afdeling 1 Rantau Baru Plantation, PT. Pusaka Megah Bumi Nusantara, which is a plantation with old oil palm plant that have entered a period of replanting (22-29 years). The NDVI analysis results show the NDVI value is 0.034-0.469. Object identification shows that non-vegetation objects have an NDVI index value of 0.034-0.245 and vegetation objects have a value of 0.273-0.454. The result of the NDVI index shows the density of oil palm plants are categorized in the high category (dense). These results are appropriate with the actual condition of oil palm plantations which have an average density of 118 trees/hectare. The average NDVI value for vegetation objects is 0.423, that indicates the plants are in fairly healthy condition. The level of plant health as the result of the NDVI analysis was in appropriate with the LSU data which showed that the content of macro and micro nutrients in the leaves was quite high. Therefore, NDVI analysis can be an alternative to evaluate the condition of oil palm plantations efficiently. Keywords: Landsat 8 sattelite imagery, NDVI index, Oil palm, Plant density, Plant health

MORFOSINTAKSIS BAHASA MELAYU BATUBARA (Kajian Pada Verba Persepsi: teŋok (lihat) dan doŋo (dengar)
Authors: BASYARUDDIN BASYARUDDIN 
Published: July 2022

Dalam bahasan linguistik terdapat kajian morfologi dan sintaksis. Pada hakikatnya morfologi membicarakan struktur internal kata, yaitu proses pembentukan kata dasar menjadi kata jadian berdasarkan peristiwa afiksasi (kata berimbuhan), reduplikasi (kata ulang), dan komposisi (kata majemuk). Kata jadian dibicarakan dari segi bentuk, fungsi, dan maknanya. Sedangkan sintaksis membicarakan kata dalam hubungannya dengan kata lain sebagai suatu satuan ujaran. Morfosintaksis bukanlah kajian morfologi dan sintaksis yang terpisah antara keduanya. Morfosintaksis adalah sebuah bidang kajian dalam linguistik, yang keberadaannya sama dengan kajian morfologi dan sintaksis. Dengan demikian morfosintaksis adalah kajian mengenai perubahan-perubahan fungsi, peran, dan kategori di dalam kalimat yang diakibatkan perubahan morfem, dan sebaliknya perbedan-perbedaan morfem/ kata yang digunakan itu adalah akibat dari proses sintaksis. Dengan demikian morfosintaksis bukanlah kajian morfologis dan sintaksis yang masing-masing berdiri sendiri secara lepas hubungan, melainkan dua bidang kajian yang saling behubungan sebagai hubungan kausal. Dalam tulisan ini diperbincangkan morfosintaksis bahasa Melayu Batubara, karena bahasa Melayu Batubara secara fonologi dan kosakata berbeda dengan bahasa Melayu lainnya, seperti bahasa Melayu Langkat, Melayu Deli, dan Melayu Tanjungbalai. Kata Kunci: morfosintaksis bahasa Melayu Batubara

Authors: SEMBIRING PENGADILEN 
Published: July 2022

Pada dasarnya dalam sebuah teks judul biasanya ditulis pada bagian paling atas, atau tengah teks dengan tidak dibubuhi tanda baca. Namun ada judul-judul teks yang ditulis dengan disertai tanda baca. Kemudian judul juga terkadang diletakkan di bawah judul atas atau judul rubrik. Fenomena seperti ini menunjukkan bahwa analisis tentang para-teks juga penting dilakukan dalam melakukan analisis wacana. Atas dasar ini penulis tertarik untuk melakukan penelitian tentang teks narasi baik dari segi para-teks, skematika, konteks, dan realisasi aksi dan reaksi wacana yang bergenre narasi yang dalam hal ini merupakan teks cerita rakyat yang berasal dari masyarakat Toba Sumatera Utara. Dengan melakukan pengkajian secara menyeluruh, peneliti dapat membantu pemahaman mahasiswa mengenai analisis wacana dengan teori Linguistik Sistemik Fungsional, tetapi juga memajukan karya sastra Indonesia melalui penggunaan sumber data cerita rakyat asal mula "Danau Toba".
