Removal of EOG Artefact from EEG – A Review
Authors: Anand Rohit , Radharapu Neha , Pradhan Pratiksha , Birok Rajesh
Published: November 2022

An electroencephalogram (EEG) is a medical examination that records the electrical activity of the human brain. In order to record these signals, electrodes are placed on the scalp, and these electrodes detect any activity of the brain cells. This result is used to diagnose patients with epilepsy, sleep disorders, brain tumors, seizure disorders, and brain disorders. However, these signals are often corrupted by various artefacts either generated from the human body(physiological) or the electrical apparatus used(non-physiological). The removal of these artefacts is vital as their presence may result in the wrong diagnosis of a disease. One of these artefacts is generated because of various kinds of eye movements, i.e. EOG. In this paper, we will be focusing on how ocular artefacts occur and how they affect the EEG signal. Later we will look into different types of artefact removal techniques and how they perform differently from each other on the basis of different factors such as signal-to-noise-ratio etc. The aim of this study is to get a detailed understanding of various ocular artefact removal techniques, challenges related to them and finding an efficient way to obtain an uncorrupted EEG signal.

Authors: Gupta Akhil , Joshi Rohan , Singh Mukhtiyar
Published: November 2022

Steganography is the study of concealing and sending a secret message by making the eavesdropper unaware of its presence. First ever attempt to propose steganography via quantum key distribution (QKD) was made by Martin in his paper where BB84 QKD was used for communicating steganographic messages. The protocol have recently been found to be insecure against a detection based steganalysis attack which uses ambiguous quantum state discrimination. In this work, we extend the previous methods to develop new continuous variable quantum steganographic protocols using QKD and analyze their performance against steganalysis.

Authors: Ram Nanak , Gautam Vijay
Published: November 2022

In the present work, three heats of Si-Mo-Cr ductile cast iron with varying amounts of major alloying elements are produced. The effect of the microstructural features on the microhardness, tensile strength and ductility is studied. Increasing the nodule count decreases the pearlite-ferrite ratio, which results in a decrease in tensile strength but an increase in percentage elongation. The spherical nodule plays a significant role in arresting the crack and reorients the crack path around the nodule, as evident from the results of scanning electron microscopy.

Background: Telemedicine (TM) contributes to bridge the gap between healthcare facilities and patients’ homes with neuromuscular disease (NMD) because of mobility issues. However, its deployment is limited due to difficulties evaluating subtle neurological signs such as mild weakness or sensory deficits. The COVID-19 pandemic has disrupted healthcare delivery worldwide, necessitating rapid measures implementation by health care providers (HCPs) to protect patients from acquiring SARS-CoV-2 while maintaining the best care and treatment. Objectives: Given the challenges faced by remote healthcare assistance of NMD patients, we aim to evaluate the use of TM in NMD during the COVID-19 pandemic. Methods: Based on the Model for Assessment-of-Telemedicine-Applications (MAST), we conducted a survey amongst clinicians of the ERN EURO NMD (European-Reference-Network-for-Rare-Neuromuscular-Diseases). Results: Based on 42 responses over 76 expected ones, our results show that the COVID-19 pandemic significantly increased the number of HCPs using TM (from 60% to 100%). The TM types most used during the COVID-19 period are teleconsultation and consultation by phone, particularly in the context of symptoms worsening in NMD patients with COVID-19 infection. Most European HCPs were satisfied when using TM but as a complementary option to physical consultations. Many responses addressed the issue of technical aspects needing improvement, particularly for elderly patients who need caregivers’ assistance for accessing the TM platform. Conclusions: TM has been essential during COVID-19, but its use still presents some limitations for NMD patients with cognitive deficits or for first-time diagnosis. Thus, TM should be used as complement to, rather than substitute, for face-to-face consultations.
Anomaly Detection in Industrial Control System Based on the Hierarchical Hidden Markov Model
Authors: Sukhostat Lyudmila
Published: November 2022

An approach based on a hierarchical hidden Markov model for anomaly detection in industrial control systems is proposed. The signals of the system components are fed to the input of the proposed model. The hidden state is an independent probabilistic model, so each state is also a hidden Markov model. In the proposed model, the detection of anomalies according to the readings of the industrial control system sensors is combined with modeling at the event level. The model has several levels, and the event is modeled at the highest level. The approach is evaluated on a secure water treatment dataset and compared with the results of the previous work, which showed that the proposed model is better in terms of recall and F-measure metrics and amounted to 0.9164 and 0.9563, respectively.

Authors: Seyhan Kübra , Akleylek Sedat
Published: November 2022

The production of quantum computers with fast processing power and practical use will adversely affect the foundations of secure communication, especially for public-key cryptosystems (PKCs). Potential problems and solution scenarios are created early to design quantum-resistant PKCs. In this paper, the emergence of the concept of post-quantum cryptography (PQC) and early precautionary actions are explained. In addition, cryptosystem families that are known/believed to be secure in the presence of quantum computers are discussed. Based on these classes, the selected encryption/key encapsulation (KEM) and signature schemes of the NIST PQC process are expressed. Finally, some open problems for the post-quantum era are summarized.

TASKS IN FORMING THE PEDESTRIAN NETWORK OF THE CITY
Authors: Sosnova Nadiia
Published: November 2022

The article raises the issue of assessment of pedestrian space assets as a means of supplementing the transport network and in the formation of urban communication systems. On the example of the city of Lviv, the possibility of optimizing the city’s radial-ring structure communications network in the conditions of the complicated development of rural transport communications in hilly terrain, by building circular pedestrian connections, is highlighted.
The basis of the research is a comparative cartographic analysis of the plan of Lviv with the use of geoinformation systems for the localization of pedestrian spaces, their dependence on the city structure.
The analysis of pedestrian traffic in Lviv shows that the existing pedestrian network – sidewalks, boulevards, pedestrian squares – duplicates the street and road network of the city. Most of the pedestrian spaces are located along the streets, bypassing the landscape areas of the city. Existing pedestrian communications do not provide connections between the main city districts with each other, with the city center and recreation places.
The task is assigned to pedestrian elements of the city – sidewalks, boulevards, alleys, etc. Three types of pedestrian communications can be distinguished according to the type of task. The first type of pedestrian communications is rationally combinated. It provids movement between point A and B. The second type is for walking and recreation. It is interpreted as rationally whole. Both involve city-wide movement. The third type of pedestrian communications is local. It involves movement within the vernacular district. It is classified as a "traditional" element in the structure of the city district.
The research considers the possibility of integrating pedestrian communications in transport network (in particular, the first type). To replace it in areas where the laying of transport connections is impossible due to planning restrictions. Consideration of pedestrian spaces as a full-fledged structural element of the city's transport and pedestrian network develops an alternative approach to overcoming communication problems between urbanized territories, separated by elements of the city's natural framework or other insurmountable planning restrictions (for example, as nature conservation landscapes or monuments).
PRINCIPLES AND TECHNIQUES OF AESTHETIC-FIGURATIVE TRANSFORMATION IN THE RECONSTRUCTION OF HISTORICAL INDUSTRIAL ENTERPRISES FOR A PUBLIC FUNCTION
Authors: Bridnia Larysa
Published: November 2022

The article deals with the issues of architectural and figurative transformation of buildings during the reconstruction of historical industrial enterprises (mid-eighteenth century – first half of the XX century). The main principles for the implementation of such a transformation are determined: ensuring urban integrity; preservation of the historical image of industrial architecture; nuances in their general architectural and spatial organization (symbiosis with the environment); contrast between old and new; compliance with national and regional cultural traditions; environmentally friendly solutions. Examples of the application of these principles in the world practice of the reconstruction of industrial buildings for various public functions are analyzed.

Techniques that allow to implement these principles in the renovation of historical buildings are defined. These methods are proposed to include: conservation and restoration of the characteristic elements of industrial architecture; reuse of authentic materials and designs; the inclusion of industrial equipment in the interiors and exteriors of objects of reconstruction; the use of forms, materials, structures, furniture – contrasting with the primary industrial structure while ensuring symbiosis with the environment due to the nuanced solution of the overall composition, the delicate inclusion of new elements, the preservation of rhythmic patterns, the use of building and finishing materials, elements of architectural «camouflage» (grids, perforations, glazing, openwork metal structures, etc.); «absorption» of old buildings or their parts by new structures. In addition, an accentuated appeal to the characteristic features of the national cultural traditions of the construction region, through the use of local building and finishing materials, forms, structures, the use of local ornaments, patterns, objects of arts and crafts is proposed. It is recommended to use environmentally friendly materials, landscaping elements in the interiors and exteriors of buildings, the formation of a building area using the natural landscape along with the inclusion of industrial elements of industrial architecture.
CHANGES IN MEDIA FORMATION OF ARCHITECTURE AND URBAN SPACES DURING THE WAR
Authors: Parneta Mariana
Published: November 2022

The article highlights the characteristics of the media formation of architecture and urban spaces during the Russian military aggression against Ukraine in 2022. There was dangerous atmosphere in the cities. Russia's invasion of Ukraine is not just an invasion, it is the beginning of a war against unity and human rights in the modern world. During the Russian military aggression, all spheres of life in Ukraine underwent changes. Everyday things have lost their meaning because the preservation of human life has become a priority. Many buildings have become shelters for refugees. The war spares nothing: neither cultural heritage sites nor human lives. The occupiers are attacking residential buildings and civilian infrastructure. As a result, peaceful people are suffering, there are victims among children. Urban spaces have undergone significant changes. The city's infrastructure has become martial law. The media formation of architecture has become a source of information for the security of the Ukrainians, has become a means of communication and expression of civic position. Sounds have also become an integral part of the media formation of the war in Ukrainian cities. First of all, it is the sound of sirens announcing – the air alarm and the urgent need to hide in a shelter. Information boards, banners, stands, and posters also remained an important element of the media formation of urban spaces during the war. To maintain the fighting spirit they depict revolutionary drawings and slogans. Russia's full-scale war with Ukraine is the agenda of the entire civilized world. So this difficult time has united not only Ukraine but the whole world. The Russian occupiers cannot conquer us. They will never reach our soul, our heart, our desire to live freely.
Challenges in identifying biomarkers for Smooth muscle tumors of uncertain malignant potential (STUMP)
Authors: Nishikawa Shoko , Hayashi Takuma , Yaegashi Nobuo , Abiko Kaoru , Konishi Ikuo
Published: November 2022

Benign uterine leiomyoma (U.LMA) and malignant uterine leiomyosarcoma (U.LMS), which are both uterine mesenchymal tumors, are distinguished by the number of cells with mitotic activity. However, uterine mesenchymal tumors contain tumor cells with various cell morphologies; therefore, making a diagnosis, including differentiation between benign tumors and malignant tumors, is difficult. For example, uterine smooth muscle tumors of uncertain malignant potential (STUMPs) are a group of uterine mesenchymal tumors for which performing a differential diagnosis is challenging. A standardized classification system for uterine mesenchymal tumors has not yet been established. Furthermore, definitive preoperative imaging techniques or hematological examinations for the potential inclusion of STUMP in the differential diagnosis have not been defined. Several clinical studies showed that there is no correlation between biomarker expression and mitotic rate or tumor recurrence. The current immunohistochemical biomarkers cannot effectively help determine the malignant potential of STUMPs in patients who wish to become pregnant in the future. The establishment of gene expression profiles or detection of pathogenic variants by employing next-generation molecular techniques can aid in disease prediction, diagnosis, treatment, and prognosis. Here, we describe the problems in diagnosing uterine mesenchymal tumors along with the results of the latest clinical studies.

Berbagai penelitian masih menyimpulkan hasil yang berbeda terkait hubungan antara investasi pro Sustainable Development Goals (SDGs) dengan return. Hal tersebut mengakibatkan adanya investor yang peduli dan yang tidak peduli terhadap SDGs dalam aktifitas investasinya.   Penelitian ini bertujuan untuk mengetahui apakah investor Indonesia peduli terhadap isu SDGs yang tergambar pada Environmental, Social, Governance (ESG) investing pada indeks SRI-KEHATI. Pendekatan yang digunakan untuk melihat ada tidaknya kepedulian investor terhadap SDGs adalah melalui perubahan volume transaksi saham sebelum dan sesudah pengumuman indeks SRI-KEHATI. Uji Shapiro-Wilk yang digunakan untuk melihat kenormalan data menunjukkan bahwa data yang digunakan dalam penelitian ini tidak berdistribusi normal. Lalu dengan menggunakan uji Wilcoxon, tidak ditemukan adanya perbedaan volume transaksi saham antara sebelum dan sesudah pengumuman baik pada saham – saham yang masuk maupun yang keluar. Dengan demikian dapat disimpulkan bahwa investor Indonesia tidak terpengaruh terhadap pengumuman indeks SRI-KEHATI. Temuan tersebut mengimplikasikan bahwa investor Indonesia masih belum peduli terhadap SDGs.

Authors: Jain Vidhi , Singh Saluja Manmeet
Published: November 2022

In the current research, rats will be given paracetamol (hepatotoxic), and the hydoethanol (HEESV) extract of the leaves of Sida veronicaefolia will be tested to see how well it protects the rats' livers from damage caused by the paracetamol. Liver function tests and serum profiles were used to provide an estimate of the hepatoprotective effects of HEESV at a dose of 500 mg/kg. According to the findings, the extracts of the chosen plant not only provide a strong hepatoprotective impact by lowering blood levels of serum transaminases (SGPT and SGOT), alkaline phosphate, and total bilirubin, but they also considerably enhance the levels of total protein. The effects of HEESV were quite similar to those of the standard medication silymarin.

Napjainkban az innovációk sűrűsödése és az értékteremtés módjának megváltozása figyelhető meg. Ez nemcsak a technológiai-gazdasági paradigmák kapcsán érzékelhető, hanem az innovációk tág körét is érinti. Az állam – kiemelten a védelmi ipar – igényei mindig is fontos szerepet játszottak a kutatás és kísérleti fejlesztés, valamint a – tág értelemben vett – piacon realizálódó innovációk ösztönzésében akár finanszírozói, akár megrendelői oldalon. Az innováció körüli „hype” és a terminológiai kakofónia miatt azonban indokolt a rendszerezés. Jelen tanulmány erre tesz kísérletet az idők folyamán fejlődött innovációdefiníciók, illetve az innovációhoz kötődő modellek áttekintésével, valamint az innovációs ökoszisztéma komplexitásának megértésére való törekvéssel.

A drogpolitika liberalizációjának társadalmi hatása
Authors: Bacsó Bernadett
Published: November 2022

A drogliberalizáció kérdésköre a mai napig vitatott téma a világban. A drogpolitika három fő pillére a drogmegelőzés,  a kábítószer-kereslet és -kínálat csökkentése, valamint az  ártalomcsökkentés. Az eltérő szigor igénye azt  eredményezte, hogy néhány országban még erősebben  tiltják a drogok birtoklását, a pszichoaktív szerek fogyasztását, mint korábban, viszont némely államban és országban dekriminalizálták az egyes kábítószerek használatát. Magyarországon a kormány jelenleg is a kényszer erejében látja a kábítószer-fogyasztás elleni küzdelem megvalósulását, nem pedig a törvények megváltoztatásában, enyhítésében. Jelenleg úgy tűnik, hazánkban a kriminalizáció nem javít a helyzeten. Érdekes  kutatások születtek a drogliberalizációval kapcsolatban,  hogy a különböző területeken hogyan hatott ez a jelenség a  fogyasztási szokásokra, illetve az orvosi kezelésekre. Ez a  tanulmány azt a célt szolgálja, hogy betekintést nyerjünk  abba, hogy az egyes országok milyen lépeseket tesznek a  gyógyászati célokat szolgáló droglegalizálással  kapcsolatosan, és ezek miként játszanak szerepet a  drogprobléma mérséklésében. A különböző országok  gyakorlata azt mutatja, hogy a gyógyászatban használt  legális drogok nem veszélyeztetik jobban az egészséget,  mint az orvostudományban alkalmazott gyógyszerek.

A bűnelkövetők körében készült nemzetközi kutatások alapján elmondható, hogy a pszichiátriai zavarok  gyakorisága kiugróan magas a normál populációhoz  képest. A bűnelkövetőket sújtó leggyakoribb pszichiátriai  állapotok között kiemelt helyen szerepelnek a  személyiségzavarok. A személyiségzavarok az Amerikai  Pszichiátriai Társaság megfogalmazása szerint azok az  eltérések, amelyek bizonyos élmény-és viselkedésbeli stabil  mintázatokban jelennek meg, és az egész személyiséget  áthatják. Ezek a kóros állapotok nagyban rontják az érintett  személy funkcionálását és alkalmazkodókészségét a környezetéhez, így nem egyszer vezethetnek deviáns attitűdhöz. A személyiségzavarok csoportjában több típust  különíthetünk el, amelyek eltérő  arányban hajlamosíthatnak deviáns, illetve erőszakos viselkedésre.  Jelen tanulmány célja az egyes személyiségzavarok  bemutatása azon aspektusaik kiemelésével, amelyek  hajlamosító tényezők lehetnek a kriminális viselkedés  kialakulásában, különös tekintettel az erőszakos  cselekményekre. Megvizsgáljuk, hogy a különböző  karakterzavarok jellemzően milyen jellegű erőszakhoz  vezetnek, illetve megkíséreljük feltárni azokat az egyes  patológiás állapotokkal járó pszichés jegyeket, amelyek  hajlamosíthatnak az agresszióra és a törvénysértő  viselkedésre.
Tájékoztatni jog vagy kötelesség? Egy ötrendbeli emberölés nyomai a magyar sajtóban
Authors: Dulai Péter
Published: November 2022

A kommunikáció minősége meghatározza a rendőrség és az állampolgárok viszonyát. Ez a megállapítás múltra-jelenre egyaránt érvényes és semmi nem utal arra, hogy ne  legyen az a jövőre nézve is. Mint minden sajtóterméknek, a  rendőrségi lapoknak is legfontosabb feladata a hiteles  tájékoztatás. Megkerülhetetlen cél és feladat emellett a  bűnmegelőzés és a bűnüldözés, ami a nyilvánosság  bevonásával történik. Vagy kellene történnie, ugyanis ez  még ma sem mindig valósul meg. Mi volt a helyzet a  közvetlen pártirányítás alatt átpolitizált rendészeti témákkal  a Kádár-korszakban? Ezt vizsgálom meg egy  kiemelt, 1961-ben Szegeden történt élet elleni  bűncselekmény kapcsán. A korszakban „szocialista  szeméremből” nem szívesen közölték azokat a bűntetteket,  amelyek az ideológia szerint távol álltak a rendszertől. A  Paprika utcai családirtásról még a helyi lapban sem  jelenhettek meg információk. Az ötrendbeli emberöléssel  kapcsolatban hetekig annak ellenére nem volt hajlandó  adatokat megosztani a rendőrség, hogy az elkövető  ismeretlen volt, és a tájékoztatás a nyomozást is előbbre  vihette volna. Befolyásolt, tájékoztatott vagy használta a  nyilvánosságot a rendőrség? Miért és hogyan tette ezt? A  21. században, mintegy hatvan évvel az események után  különösen érdekes és tanulságos megvizsgálni, hogy egy  ilyen súlyos bűncselekmény kapcsán milyen szempontok  alapján szorult háttérbe az állampolgárok védelme a  rendőrség részéről.

Translating Paralinguistic and Onomatopoeia: An Analysis on the Novel “Bumi Manusia” by Pramoedya Ananta Toer and its Translation ”This Earth of Mandkind” by Max Lane
Authors: Wiles Erna
Published: November 2022

This article is a descriptive qualitative study that aims to describe the challenges and strategies in translating paralinguistic and onomatopoeias. Data were collected from a novel by Pramoedya Ananta Toer “Bumi Manusia” and its translation “This Earth of Mankind” by Max Lane. Content and discourse analyses were performed through reductions, codings, displays, and verifications. The analyses came to a conclusion that paralinguistic (and non- linguistic) as well as onomatopoeic features are culturally bound. Ones can exist in a language community but may not in another, and the adoptions can also differ; thus, the equivalence cannot be fully maintained. Analyses on "Bumi Manusia" and its translation on its paralinguistic and non-linguistic features including onomatopoeia showed that to achieve the optimum equivalence, some steps need to be conducted. For paralinguistic and non-linguistic features two steps are needed i.e., following the target language syllabication system and adding more descriptions/illustrations on the scene to emphasize the clarity of the context; while four steps are needed to translate onomatopoeias i.e., by using onomatopoeias of the target language with the closest meaning to that of the source language, combining several onomatopoeias, lexicalizing, and using an onomatopoeia of different part of speech.Keywords: translation, paralinguistic, onomatopoeia

Consonant Production of an American-English Native Speaker from 3 to 6 Years Old: A Case Study on a Child named Brielle
Authors: Anwar Aghnia Dianah , Hardjanto Tofan Dwi
Published: November 2022

ABSTRACTChildren’s phonological development is somewhat foreseeable, yet there are certain sounds that appear at different ages across children. However, there are some general guidelines which can be used to analyze the phonological development of a child. This study aims to examine the phonological development process of an American English native speaker named Brielle in producing consonants from the age of three to six using the speech sound development milestones provided by Sander (1972). The data are taken from youtube videos of Brielle when appearing on an American talkshow called “The Ellen Show”. A descriptive qualitative method is used in this study to elaborate the phonological development of Brielle. The result shows that Brielle completed her phonological development at the age of six. It can also be concluded from the study that some consonants appear earlier or later thatn the phonological development milestones set by Sander (1972). During the process of acquiring consonants, she replaced the consonant which she could not produce with another sound with similar features, such as replacing the liquid sound /l/ with the glide sound /j/.
