Published: February 2021

Thanks to social media, people are now able to leave guiding comments quickly about their favorite restaurants, movies, etc. This has paved the way for the field of sentiment analysis, which brings together various disciplines. In this study, Yelp restaurant reviews and IMDB movie reviews dataset were used together with the data collected from Twitter. Word2Vec (W2V), Global Vector (GloVe) and Bidirectional Encoder Representation (BERT) word embedding methods, Term Frequency-Reverse Document Frequency (TF-IDF), and the Bag-of-Words (BOW) were used on these datasets. Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM), Recurrent Neural Network (RNN), Support Vector Machine (SVM), and Naive Bayes (NB) were used in the sentiment analysis models. Accuracy, F-measure (F), Sensitivity (Sens), Precision (Pre), and Receiver Operating Characteristics (ROC) were used in the evaluation of the model performance. The Accuracy rates of the models created by the Machine Learning (ML) and Deep Learning (DL) methods using the IMDB dataset were in the range of 81%-90% and 84%-94%, respectively. These rates were in the range of 80%-86% and 81%-89% for the Yelp dataset, and in the range of 75%-79% and 85%-98% for the Twitter dataset. The models that incorporated the BERT word embedding method have the best performance, compared to the other models with ML and DL. Therefore, BERT method is recommended for this type of analysis in future studies.

Published: February 2021

The purpose of this study is to investigate the impact of rumors on both individuals and the society at large in Saudi Arabia. Over the past several decades, the Internet has dramatically changed the manner in which modern society communicates. In particular, online media have altered how rumors are transmitted, from hearing those rumors - ranging from word of mouth among people to misleading online messages. Although the manner in which rumors are circulated has evolved over time, only a few studies have been conducted on the dynamics of how rumor spreads on the social media in Saudi Arabia. It is worthwhile to discuss the impact of rumors on individuals and the society in Saudi Arabia and determine the factors affecting the impact of rumors in Saudi Arabia. In this research study, two variables have been discussed, i.e. dependent and independent variables: the impact of rumors on both individuals and the society at Saudi Arabia, which shows dependency upon independent variables such as Uncertainty, Belief, Motivational Factors and Self-Enhancement. Quantitative research method has been used for this study that entails a total of 200 used survey questionnaires to collect vital information regarding the topic of investigation.
Impact of Task-Based vs. Presentation-Practice-Production Instructional Methods on Students’ Productivity Skills
Authors: Ho Pham Vu Phi , Huyen Do Thi
Published: February 2021

The article compares the impacts of two instructional methods— Presentation-Practice-Production and task-based language teaching—to understand if there are any differences between the two in terms of improving students’ productivity skills. Seventy-eight students at Van Lang University, Ho Chi Minh City, Vietnam participated in the study. Students in the control group were trained using the Presentation-Practice-Production method, while those in the experimental group were trained using the task-based instruction method. Data was collected pre-test and post-test in response to the three research questions. The findings indicated that the task-based instruction model had a great impact on students’ grammatical performance in both writing and speaking, but was not superior to the Presentation-Practice-Production model. New research results confirmed the effectiveness of both methods when teachers put significant effort into their instructional activities.
EFL Learners’ Perceptions about the Use of Mobile Learning during COVID-19
Authors: Rahman Mohammed Mahib Ur
Published: February 2021

Mobile learning has recently emerged as a powerful and frequently used tool in the teaching-learning curriculum. Besides, it also attracted the attention of EFL teachers and learners across the globe. Its acceptance in EFL learning is mainly because of the two fundamental functions, i.e., anytime and anywhere. As a result, the pioneers and scholars who work in second or foreign language learning have largely recognized its impact and importance. Furthermore, since the outbreak of the COVID-19 pandemic, the regular traditional classes have been severely affected, and teaching has been carried out by online method. As a result, mobiles and tablets have primarily been used along with other electronic gadgets. Therefore, this paper aims to examine EFL learners' perceptions about m-learning for their learning activities during COVID-19 at Qassim University, Saudi Arabia. A questionnaire has been prepared by keeping the use of the mobile device in view that can benefit Saudi EFL learners, and distributed among 50 EFL male and female students. Later, a quantitative analysis of the responses has been done by using SPSS 26. The study identified healthy and positive perceptions of m-learning. The significant findings will be valuable for the teachers and administrators concerning m-learning in language teaching.
Model For Mixing Process Improvement at Water Treatment Plant by Integrating Lean Manufacturing and Parameter Design
Authors: Tamjidillah Mastiadi , Irawansyah Herry
Published: February 2021

The aim of integrating lean manufacturing and parameter design is to minimize seven non-value wastes in addition to the traditional waste in clean water production. These additional wastes to be considered are overproduction, waiting, motion, transportation, inventory, overprocessing, and defects. Information obtained from each waste is the input for the parameter design of the mixing process. The result of interaction between these seven types of waste in the lean production of clean water reveals that overprocessing waste is the most influential input in the parameter design of the Taguchi method. In the process of adding the level of concentration of poly aluminium chloride coagulant in the mixing process, a turbidity level below 5 nephelometric turbidity units is obtained, which in fact is in accordance with the health standard for clean water. An observation was also made on the behavior of flocs as the effect of Brownian motion due to the attractive force of poly aluminium chloride coagulant and colloid particle. The particle was then examined using a scanning electron microscope to find out the dimension of grain-sized flocs as the result of sedimentation in the mixing process. By properly integrating lean manufacturing and parameter design to minimize waste, a quality water meeting the set standard would be produced.

Published: February 2021

On-site traditional methods to build items of homes with affordable prices are time-consuming. The adoption of ready and shaper technology, not only allows faster construction but also a better Economy. For many years Iraq engineering work for roof flatness used to use which is a square board with a length of 400, 600, or 1000mm, yet the procedure and the production need many improvements. One of the disadvantages of this production is the heavyweight and the big amounts of cement that need. So in this research, we made a trial to solve this difficulty using geopolymer concrete and lightweight artificial coarse aggregate. The article describes a new method used first time in Iraq based on the geopolymer concrete technique using fly ash as cementitious material and sodium silicate and hydroxide sodium as alkali-activated solutions and lightweight artificial coarse substances as aggregates enabling to produce lightweight tile. The produced tiles of research results have 35%, 50% less in weight, and thermal conductivity respectively than the normal tile which improved in Iraqi tiles and can be used for roof flatness.

Authors: Syaiful Syaiful , Iswahyudi Iswahyudi
Published: February 2021

This article explains the low noise that originates from the volume of public transportation and private transportation during COVID-19 (few vehicles are passing). The method used is surveying traffic data in the field (the noise is measured when the vehicle passes the roadside of the survey location), including when COVID-19 hits the city. This study refers to several cities, including the city of Bogor as the object of research. Traffic movements have slowed down due to the COVID-19 outbreak. This field method is effective in describing the current traffic conditions. In the findings, the indicator used to determine the vehicle volume noise contributes 12.10% of the calculation result of y = 70.718 + 0.013 x 1. The result is a significant effect seen on sound level meter (SLM) 3, with an increase of 70.718 dBA, distance from the sidewalk to the nearest building wall of 10.24 m, and vehicle speed of 80 km/hour. The results of this study will enhance the development of science and engineering technology as a contributor to cooperative support of government policies to comply with health protocols in this COVID-19 era.

O odpowiedzialności – w dialogu z Martinem Buberem
Authors: Gorczyca Jakub
Published: February 2021

Około trzydziestu lat temu G. Picht pisząc esej filozoficzny o pojęciu odpowiedzialnosci mógl stwierdzić, ze zna tylko jedną monografiię poswieconą temo zagadnieniu. Dzisiaj istnieje juz wiele studiów o odpowiedzialności, a wydana w niedługim czasie po publikacji Pichta rozprawa R. Ingardena, zdążyła stać się klasyczną. Pomimo tej obfitości analiz - a raczej, dzięki niej - pytania o odpowiedzialność i „do odpowiedzialności" powracają. Rodzą się one zresztą nie tylko w kontekscie uczonych dysput (i dysput uczonych); przynosi je „samo życie". To przecież codzienność jest miejscem „zdziwienia" i impulsem dla ruchu mysli filozoficznej. Do tejże codzienności filozofia nieustannie powraca, w zamiarze dochodzenia do tego, "jak jest naprawdę". W niniejszych rozważaniach o odpowiedzialności, nie rezygnując z odniesienia do potocznego doświadczenia, chcemy wejść w dialog z myslą Martina Bubera, który swoje zadanie filozoficzne pojmował jako "prowadzenie rozmowy" i wskazywanie „na coś w rzeczywistości, co nie zostalo zauważone lub jest za mało dostrzegane". Był on jednym z tych myślicieli, dzięki którym pojęcie odpowiedzialności zostało wprowadzone do filozofii i teologii w nowym, a przynajmniej „malo dostrzeganym" przez tradycję znaczeniu. Jakie to jest znaczenie? A jakie było tradycyjne?
Władza państwowa a społeczeństwo obywatelskie w świetle nauki społecznej Kościoła
Authors: Koperek Jerzy
Published: February 2021

Katoicka nauka spoleczna koncentruje się wokół zagadnień godności osoby ludzkiej oraz wynikających z niej uprawnień indywidualnych i spolecznych. Jednym ze szczególnych uprawnień jest prawo do wolności obywatelskiej, wyrażające się w wolności działania, myślenia, przekonań religijnych i możliwości budowania spoleczeństwa obywatelskiego. Prawo do wolności jest często rozpatrywane także w kontekście różnych filozoficznych koncepcji, a zwłaszcza w filozofii liberalnej. We współczesnej historii Polski tego rodzaju myśl wolnościowa związana była z istnieniem opozycyjnych ugrupowań dysydenckich i politycznych. Interesującym zagadnieniem z punktu widzenia powstawania neoliberalnej idei wolnosci w ramach opozycji demokratycznej przed 1989 rokiem w Europie Środkowo-Wschodniej jest zwrócenie uwagi na
dwa podstawowe elementy myslenia na przekór komunistycznej tradycji. Pierwszym z tych zagadnieh jest problematyka autonomii jednostki. Drugie zagadnienie natomiast mozna okreslic mianem spoleczehstwa
obywatelskiego.

Doświadczenie religijne w rozumieniu Antoniego Vergote'a
Authors: Głaz Stanisław
Published: February 2021

Historia religii jednoznacznie wskazuje, że religia nie stanowi wyłącznie jakiejs idei ani że nie jest jedynie systemem praktyk kultowych. Jest przede wszystkim spotkaniem czlowieka z sacrum, z boskością, i nawiązaniem dialogu z rzeczywistością transcendentną. Do spotkania z sacrum moze dojść na drodze poznania wewnętrznego, na podstawie obserwacji świata odczytywanego jako symbol czegoś ponad nim, słuchania słowa Bożego, doznawania wizji lub oświecenia. Jest ono uwarunkowane działaniem całego czlowieka, zarówno jego uczuć, jak i rozumu. W tym spotkaniu człowiek otwiera się na sacrum całym sobą, w swej psycho-fizycznej strukturze. Antoine Vergote, współczesny psycholog belgijski, ukończył studia fiozoficzne i teologiczne w Lowanium. Formację psychologiczną i psychoanalityczną zdobył w Paryżu. W praktyce zawodowej i w badaniach naukowych zajął sie problematyką religijnosci jednostki. Interesuje go przede wszystkim problem doświadczenia religijnego. Szuka odpowiedzi na pytanie: w jakim stopniu potrzeby, pragnienia i frustracje oddziałują na postawy religijną człowieka? W szczególności, w jakim stopniu obrazy ojca i matki mają wpływ na postawy religijny dziecka? Co sprawia, ze człowiek jest religijny?

Jeszcze niedawno spory koncentrowany się wokół zupełnie innego tematu - kwestii, czy i na ile mamy poddać się inżynieryjno-genetycznej samoinstrumentalizacji lub dążyć wręcz do samooptymalizacji. Właśnie o pierwsze kroki stawiane na tej drodze rozgorzał spór pomiędzy rzecznikami dwóch wielkich potęg wiary - zinstytucjonalizowanej nauki i Kościoła. Obawy pierwszej strony dotyczyły obskurantyzmu i kierowanego sceptycyzmem wobec nauki osłaniania archaicznych reliktów emocjonalnych, strona druga zwracała się przeciw scjentystycznej wierze w postęp głoszonej przez podkopujący moralność, brutalny naturalizm. Tymczasem 11 września napięcie pomiędzy społeczeństwem laickim a religią eksplodowało w całkiem inny sposób.

Design at the root of biophilia. Imitation. Nature.
Authors: Marciniak Marcin , Latała-Matysiak Dżoana
Published: February 2021

According to the current state of research on the phenomenon of biophilia, the positive influence of nature's elements on humans has long been widely understood. Since the negative impact of urbanised areas on quality of life was noticed, human-friendly architecture has been redefined, where the physical and mental well-being of people using buildings, remains highly dependent on their contact with the environment. Selected examples of existing buildings analyzed two different approaches to contemporary biophilic architecture; one where nature is the pedestal of the whole building and one where the interpretation of nature translates into technological, engineering or structural solutions. The architectural examples modelled on nature, have gained recognition in local communities and worldwide renown, so it can be concluded that the flourishing of organic and bionic architecture is fully justified. Biophilia determines human well-being, while remaining closely related to the natural environment.
Development of radiochromic dosimeters based on polyvinyl chloride films containing 2′-anilino-6′-di-n-pentylamino-3′-methylfluoran (Black305)
Authors: Kawamura Ichiro , Kawamoto Hiroki , Fujimoto Yutaka , Koshimizu Masanori , Asai Keisuke
Published: February 2021

We fabricated polyvinyl chloride (PVC) films containing 2′-anilino-6′-di-n-pentylamino-3′-methylfluoran (Black305) to develop radiochromic materials with high sensitivity to radiation. The optical absorption spectra of these films before and after X-ray irradiation were measured, and for comparison, we also investigated the absorption spectra of polyvinyl butyral, poly(methyl methacrylate), and polystyrene films containing Black305. The absorbance at 460 and 600 nm increased with the X-ray dose, and the change in the absorbance of the PVC film integrated over wavelengths 350–800 nm was 3.2 × 102–8.1 × 102times those of other films at a radiation dose of 0.5 kGy. This suggests that the oxidation of Black305 proceeds efficiently by radicals generated from PVC. The sensitivity to radiation of the PVC film was 4.4–51 times greater than that of conventional plastics containing leuco dyes, and the lower limit of detection of 1 mm PVC film containing 1 wt% Black305 was 0.11 Gy, suitable for radiotherapy dosimetry.
Influence of adsorbed oxygen concentration on characteristics of carbon-doped indium oxide thin-film transistors under bias stress
Authors: Kobayashi Riku , Nabatame Toshihide , Onaya Takashi , Ohi Akihiko , Ikeda Naoki , Nagata Takahiro , Tsukagoshi Kazuhito , Ogura Atsushi
Published: February 2021

To clarify a factor on the reliability, we investigated the characteristics of carbon-doped indium oxide (InO1.16C0.04) thin-film transistors by varying the O2 concentration from 0.001% to 100% at atmospheric pressure under negative bias stress (NBS) and positive bias stress (PBS). A positive threshold voltage (V
th) shift was observed when the bias stress was changed from NBS to PBS. The positive V
th shift increased with increasing bias voltage irrespective of the O2 concentration. This behavior was attributed to the reaction between adsorbed O2 molecules on the back side of the InO1.16C0.04 channel and the electrons in the channel being strongly enhanced under PBS. We have found the magnitude and direction of the bias stress play an important role in the positive V
th shift under environments included O2 at concentrations as low as 0.001%.
Resonance control by setting a phase adjuster or expanding phase adjuster for improving the performance of coaxial-type thermoacoustic system
Authors: Onishi Riku , Sakamoto Shin-Ichi , Kawashima Yuto , Hiramatsu Koto , Watanabe Yoshiaki
Published: February 2021

Sound field control to suppress resonance transition from fundamental mode to secondary mode, that was a significant problem in coaxial-type thermoacoustic system, is examined by modifying the acoustic tube. The experiments are carried out by applying a phase adjuster (PA) or an expanding phase adjuster (EPA) which has been used for a different thermoacoustic system. The position for installing PA or EPA is determined based on the experimental results for the sound field. It is demonstrated that the suppression effect of the secondary mode is enhanced as the thickness of PA or the inner diameter of EPA increases and PA and EPA then affect the phase of the sound field in the tube. Furthermore, an advantage for actual application that the phase at the setting position of HP approaches the phase of traveling wave and the system performance is improved by the increased traveling wave component is also confirmed.

Authors: Das Karuna Kanta , Dutta Bijoy Kumar , Gogoi Chintumoni
Published: February 2021

Objective- To compare the relative efficacy and success rate of combination of mifepristone and misoprostol with misoprostol alone in mid-trimester abortion by correlating induction abortion interval (IAI) between two study groups. Methods- A comparative study was carried out by dividing 100 women seeking for abortion into two groups (50 each). GroupA received 200mg mifepristone orally followed by 600mcg misoprostol vaginally (24 hours later) which was repeated 4 hourly by 400mcg sublingual misoprostol upto a maximum of 5 doses. GroupB received 600mcg misoprostol vaginally and dose was repeated 4 hourly by 400mcg of misoprostol sublingually. Result- the success rate in GroupA was 100%, whereas in Group B was 94%. The mean IAI in GroupA was lesser (10.8 hours) as compared to GroupB (13.5 hours) p value 0.01. The mean dose of misoprostol in GroupA was 1400mcg compared to GroupB 1760mcg (p value 0.0001). Conclusion- Pre-treatment with mifepristone significantly shortens the IAI and increase the successful abortion rate.
COMPARISON OF SEMI-AUTOMATED CT VOLUMETRY AND INTRAOPERATIVE GRAFT WEIGHT IN POTENTIAL DONORS FOR LIVING DONOR LIVER TRANSPLANTATION (LDLT)
Authors: Moorthy Srikanth , Shibu G. , Devarmani Sanjana
Published: February 2021

Aim:
The aim is to study the correlation between estimated graft weight (EGW) and actual graft weight (AGW) in potential donors for LDLT.
Materials and Methods:
The study cohort consisted of 133 right lobe (RL) with middle hepatic vein (MHV), 23 RL without MHV and 17 left lobe (LL) grafts assessed between August 2018 and August 2020. EGW was calculated using semi-automated volumetry technique in Philips IntelliSpace portal workstation and AGW was measured intra-operatively by the transplant team after graft retrieval from the donor. To find the agreement between AGW and EGW, intra-class correlation co-efficient (ICC) was computed. To find the degree of correlation between EGW and AGW, Spearman’s rho correlation co-efficient was computed. Bland Altman plot was used for assessing the level of agreement between two methods.
Results:
The mean age of donors was 38.9 +/- 9.9 years (Female:Male::121:52). The correlation between EGW and AGW for all three types of grafts was significant (p<0.001). RL with MHV: Spearman’s rho r=0.786, ICC=0.883; RL without MHV: Spearman’s rho r= 0.968, ICC=0.986 and LL: Spearman’s rho r= 0.809, ICC=0.937. Bland Altman’s analysis showed that CT volumetry overestimated 5 and underestimated 1 RL grafts with MHV, overestimated 1 RL grafts without MHV and underestimated 1 LL grafts.
Conclusion:
CT volumetry has a definitive role in the pre-operative evaluation of prospective liver donors. EGW calculated by semi-automated CT volumetry in potential LDLT donors is accurate and correlates well with AGW measured intra-operatively for both right and left lobe grafts.

Benign intrahepatic cholestasis (BRIC) is a rare genetic disorder characterized by episodic cholestasis. Each episode is characterized by repeated episodes of jaundice, intense pruritis last for weeks to months with complete remission. Although each episode is associated with significant morbidity, progressive liver injury and cirrhosis do not occur. In recent studies, few patients progressed to Progressive familial intrahepatic cholestasis. Here we report a case of 19 years boy with benign intrahepatic cholestasis due to an undulant course terminated by plasma exchange.

Authors: Naik D.V.Rama Siva , Kumar J.Sudheer
Published: February 2021

The physiological response to surgical stress and anaesthesia is well documented. Laparoscopic surgery which involves insufflation with carbon dioxideproduces undesirable responses like hypertension, tachycardia and dysrhythmias. Introduction of Dexmedetomidine which is highly specific and selectiveα2 adrenoceptor agonist has been tried in various studies to modify the stress response to surgery and to have a pleasant anaesthetic outcome with minimal cardiovascular changes. In our present study we have taken the pharmacological advantage of Dexmedetomidine to study the various cardiovascular parameters at different periods during the laparoscopic procedure. The aim is to studythe effectiveness of Dexmedetomidineinattenuating the sympathetic response tolaryngoscopy and endotracheal intubation and in maintaining the hemodynamic stability in laparoscopic cholecystectomy.
Materials & Methods:
30 ASA I and II patients of either sex, scheduled for elective Laparoscopic Cholecystectomy under General anaesthesia were randomly allocated to receive either 1mcg/kg of Dexmedetomidine in 100ml of 0.9% normal saline (Group D,n=30) or 100ml of 0.9% normal saline(Group S, n=30) 30min beforeinduction.
Results:
In patients who received Dexmedetomidine there was a statistically significant differencein heartrate, systolic blood pressure, diastolic blood pressure and meanarterial pressures during Laparoscopy and Intubation.
Conclusion:
Dexmedetomidine when given as a premedication before Laparoscopic Cholecystectomy attenuates the sympathetic response to laryngoscopy and intubation and provides stable intra operative hemodynamics.

Published: February 2021

Background: Living donor liver transplantation is being used as the main therapeutic option in the management of end-stage liver disease patients especially since there is inadequate availability of deceased donors. Degree of hepatic steatosis in prospective liver donors can affect the tissue regeneration in both donors and recipients and as well as the success of the surgery. MRI-PDFF is the best modality for the non-invasive assessment of hepatic steatosis in the literature, however CT is more commonly employed for the same. The qualitative data of hepatic fat using CT based methods are compared with MRI-PDFF based gradings.
Methods: The study included 35 prospective liver donors assessed between August 2018 to August 2020. All patients were evaluated with MRI- PDFF (IDEAL) sequence and fat fraction maps were obtained. The mean fat percentage was calculated and grading of hepatic steatosis was done. In plain MDCT 0.5 mm CT cuts, mean values of hepatic CT attenuation values corresponding MRI fat fraction maps were taken. Grading of the hepatic steatosis based on CT parameters like liver-spleen attenuation ratio (L/S) and liver-spleen attenuation difference(L-S) was done. Both CT and MRI based gradings were assessed for any statistical difference.
Results: The categorical data (grading) based on MR derived fat fraction and both CT based parameters mentioned above were evaluated with Chi Square test that showed no significant difference (p = 0.083).
Conclusion: Grading of hepatic steatosis using CT based parameters shows no statistically significant difference with MRI-PDFF based grading.

Authors: Sanyal Debasish , Mukherjee Priya
Published: February 2021

Background: Several studies have shown a relationship between depression and low levels of Vitamin D in the body. At the same time, somatisation is found to be a significant complaint in many patients of depression. Whether somatisation has any relationship with the low levels of Vitamin D, needs further research.
Aims: To compare the prevalence of Vitamin D deficiency between depressed and non depressed subjects, and see if somatic presentation of depression has any correlate with Vitamin D deficiency.
Design: Observational, cross-sectional, hospital- based study.
Materials & Methods: The study was conducted in the Department of Psychiatry, in a Private Hospital. Diagnosed MDD patients consenting to participate in the study, & sex matched controls, comprising of close family members of patients were selected. Detailed assessment of depression symptomatology was done. Assessment of somatization was done using Bradford Somatic Inventory. Blood samples were collected for routine tests and Vitamin D (total) estimation.
Results: In the group of MDD patients, the mean age of females is 52 years, & mean age of males is 50 years. In the MDD group, the mean Vitamin D level is 17.12; in the control group, the mean Vitamin D level is 22.19. The difference is statistically significant. Among MDD patients, 70% had deficiency of Vitamin D. In the Severe somatic symptom category, 68.3% had deficiency of Vitamin D; in the Mild somatic symptom category, 66.7% had deficiency of Vitamin D. The difference is not statistically significant.
Conclusion: Depression patients have significantly higher proportion of Vitamin D deficiency cases. Depressed patients with higher number of somatic symptoms have lower vitamin D level, but the difference is not significant.
