A STUDY OF CULTURAL DIFFERENCES BETWEEN CHINA AND RUSSIA FROM THE RUSSIAN TV SERIES HOW I BECAME RNSSIAN
Authors: Чэнь Ц.
Published: September 2022

Кино и телевидение – один из важнейших способов содействия распространению и обмену культурами между различными этническими группами. Различные культурные группы знакомятся с культурой других стран через кино и телевидение, завершая процесс тонкой межкультурной коммуникации. В данной статье рассматриваются культурные различия между Россией и Китаем в пяти аспектах: винная культура, банная культура, культура суеверий, культура дарения подарков и культура смеха, на основе анализа содержания российского телесериала «Как я стал русским». В процессе культурного обмена важно понимать, ценить и терпимо относиться к культурным различиям между друг другом, чтобы разрушить культурные барьеры и способствовать взаимным обменам и контактам.

Film and television works are one of the important ways to promote the cultural communication and communication of various nationalities. Different cultural audiences understand other cultures through film and television works, and complete the process of cross-cultural communication imperceptible. This paper studies the cultural differences between China and Russia in five aspects: wine culture, bath culture, superstition culture, gift giving culture and laughing culture by analyzing the content of The Russian TV series How I Became Rnssian. In the process of cultural communication, only by understanding and tolerating each other’s cultural differences can cultural barriers be broken and exchanges and connections between each other be promoted.
People with Special Needs and Career Development Based on Strength
Authors: Drobnič Janez
Published: September 2022

The present work deals with career counselling for people with special needs based on the paradigm of positive psychology, which is becoming increasingly relevant in counselling and therapeutic processes. It is an approach to counselling and working with clients based on the strengths of the individual and represents a paradigm shift – a departure from the approach based on deficits and weaknesses. The empirical study established the prevalence of this approach in Slovenian elementary and secondary school counsellors. The results show that this way of counselling is a new strategy for mobilising various internal sources of strength and a supportive environment, which improves the individual’s ability to achieve the best possible self-sufficient education and integration into professional and social life. However, in the case of counselling for persons with special needs, a balance needs to be achieved between a strength approach and others that focus on personal problems and weaknesses.
Krim – Erkundungen am Rand Europas
Authors: Hofmann Tatjana
Published: September 2022

The Crimean peninsula in the Black Sea, rich in history and charm, is of great geostrategic importance. This leads to political conflicts time and again. But what is everyday life like in Crimea beyond the discourses about law, borders and war? What do local intellectuals think about the situation today? Can Geopoetry help to counteract the current crisis? Tatjana Hofmann's ethnographic long-term observation explores these questions. Her poetic essay, illustrated with magnificent photographs by Alexander Barbuch, transcends the usual boundaries of genre and searches for perspectives far removed from common patterns of interpretation. Tatjana Hofmann, a Slavist and author, lives in Zurich. "Krim – Erkundungen am Rand Europas" continues her 2015 novel "Sewastopologia" continues.

The objective of this study was to evaluate the different levels inclusion of corn DDG in the laying hens diet and its effects on the performance, egg quality, yolk pigmentation and economic analysis. A hundred fifty laying hens (Hisex Brown) were distributed in a completely randomized design with five treatments and six replicates, with five birds per experimental unit. The diet formulations met the nutritional requirements of the chickens, using the following treatments: control diet with the inclusion of 0% of DDG; inclusion of 5%, 10%, 15% and 20% of DDG. There was no effect (P> 0,05) on egg quality and performance parameters, the yolk coloring, by the colorimetric spectrum and digital colorimeter (L and a *); there was an effect with DDG inclusion (P <0,05).  The corn DDG has a coloring potential in the egg yolk, making it appear more yellow, without influencing the performance and egg quality on laying hens, besides being a more economical product.

Published: September 2022

A mastite bovina é considerada a doença de maior prevalência nos rebanhos leiteiros no mundo, impactando produtores, indústria de laticínios e influenciando negativamente a qualidade do leite, além do impacto na saúde pública. Nesse contexto, objetivou-se traçar o perfil microbiológico dos agentes causadores da mastite bovina em propriedades leiteiras da microrregião do Agreste e Brejo paraibano entre o período de agosto de 2018 a dezembro de 2019 e avaliar o comportamento da dinâmica do California mastitis test (CMT) em diferentes perfis microbiológicos do leite. Foram analisadas um total de 421 amostras de leite provenientes de 920 quartos mamários de 230 vacas que foram submetidas ao diagnóstico da mastite clínica (MC) e subclínica (MSC). Observou-se uma expressiva ocorrência de casos de MSC (n = 370, 40,22%) e de MC (n = 51, 5,54%). As amostras de quartos mamários com MC ou MSC resultou em 16,63% de ausência de crescimento no exame microbiológico. Das amostras com crescimento microbiológico, Staphylococcus spp. (26,36%), Corynebacterium spp. (22,32%) e Streptococcus spp. (12,59%) foram os microrganismos mais frequentemente isolados, já os agentes etiológicos ambientais foram esporadicamente isolados. Na avaliação da dinâmica do CMT observou-se que as amostras com resultado positivo no CMT e negativos no exame microbiológico apresentaram tendência a uma redução expressiva dos escores de CMT no momento da coleta subsequente (após 30 dias). Os resultados demonstram a necessidade de realizar educação no processo de ordenha na região, bem como, reforçar a importância do uso do CMT e do exame microbiológico de forma criteriosa no controle da mastite bovina.

Published: September 2022

Piolhos mastigadores são normalmente encontrados em aves e mamíferos. Esses insetos são divididos em duas subordens de importância nas aves, a Amblycera e a Ischnocera, sendo que nesta última apenas a família Philopteridae abrange os piolhos específicos desses animais. Possuem as peças bucais adaptadas à mastigação da pele e penas, e quando parasitam aves como as calopsitas (Nymphicus hollandicus) podem provocar diversas alterações dermatológicas, sistêmicas e até mesmo comportamentais. O objetivo deste estudo foi relatar o encontro de espécimes de piolhos do gênero Neopsittaconirmus infestando uma calopsita domiciliada em Teresina, PI, proveniente de um criatório comercial. O animal era de mutação lutina, com 3 meses de idade, que apresentou apatia, penas eriçadas e prurido. Ao atendimento veterinário observou-se a presença de piolhos sobre as penas da ave, sendo as mesmas colhidas e levadas ao Laboratório de Parasitologia da Universidade Federal do Piauí, confirmando infestação por piolhos Neopsittaconirmus spp. O animal foi tratado com selamectina tópica em dose única e suplemento vitamínico, observando melhora do quadro clínico e ausência de piolhos quinze dias após a terapia. Até o presente conhecimento, este relato apresenta a primeira descrição de piolhos do gênero Neopsittaconirmus em calopsita no nordeste do Brasil. Conclui-se que piolhos desse gênero podem infestar e provocar lesões nessas aves, sendo recomendado o diagnóstico precoce e um tratamento adequado para eliminar estes ectoparasitos.
Noise detection and suppression in ECG using adaptive filter algorithm
Authors: Chinmay Chandrakar
Published: September 2022

A novel Power Line Interference (PLI) detection and suppression algorithm is proposed to preprocess Electrocardiogram (ECG) signals. A distinctive feature of this algorithm is the ability to detect the presence or absence of PLI in the ECG signal before applying the PLI suppression algorithm in the ECG signal. Only after the detection of PLI, it can be suppressed. We propose a PLI detector employing a classifier designed based on observations of the Root Mean Square (RMS) values of noise and reference ECG signals. An efficient recursive Least Mean Square (LMS) adaptive notch filter was also developed to serve the purpose of PLI suppression. An adaptive filter consists of a digital filter with adjustable coefficients and an LMS algorithm to modify the coefficient values to filter each sample. Experimental results demonstrate superior performance of this proposed algorithm.

The Wide Variety of Acute Disseminated Encephalomyelitis in Children: A Clinical Perspective
Authors: Lim Hyunsuk , Hwang Su-Kyeong , Lee Yun-Jeong , Kwon Soonhak
Published: September 2022

Acute disseminated encephalomyelitis (ADEM) is an acute demyelinating inflammatory disorder of the central nervous system. It is characterized by encephalopathy, multifocal neurological deficits, and typical magnetic resonance imaging findings of widespread demyelinating lesions, predominantly involving the white matter of the brain and spinal cord. ADEM mainly affects children and is commonly associated with preceding viral and bacterial infections, and, rarely, vaccinations. Despite substantial advances in the understanding of the association of myelin oligodendrocyte glycoprotein antibody with recurrent forms of ADEM or other demyelinating conditions, specific etiologic agents or biological markers have not been identified. Therefore, the diagnosis of ADEM is still based on clinical and radiological findings and the exclusion of other conditions mimicking ADEM. However, a prompt diagnosis and adequate treatment are crucial because diagnostic delays or inappropriate treatment may lead to unwanted neurological sequelae in some children. There is no standardized treatment protocol for ADEM, but the use of corticosteroids, intravenous immunoglobulin, and plasmapheresis has been associated with good clinical outcomes. Adequate treatment has reportedly resulted in favorable outcomes, with full or almost full recovery in most children with ADEM, although some children may develop neurological sequelae, such as cognitive impairment and motor deficits. Further studies are needed to identify biological clues and optimal treatment protocols to minimize the incidence of neurological sequelae.
Jeszcze raz w sprawie pielgrzymki księcia szczecińskiego Świętobora I do Ziemi Świętej w 1411 r.
Authors: Zdrenka Joachim
Published: September 2022

The author of the commentary does not engage in a polemic with Krzysztof Kwiatkowski’s article “Niewola księcia pomorsko‑szczecińskiego Kazimierza [V] po bitwie grunwaldzkiej (1410/1411) – obserwacje historycznokulturalne” (Studia z Dziejów Średniowiecza 2017, vol. 21, pp. 111–126). However, he draws attention to Kwiatkowski’s erroneous interpretations, in which, without offering any new arguments, he asserts “facts” that do not emerge from the cited sources. The author suggests that we are dealing here with historical fantasy that has no place in serious history. Kwiatkowski also commits errors in citing sources and does not take account of the most important study of pilgrimages to the Holy Land. Summing up, the author of the commentary claims that the subject of Prince Świętobor I’s pilgrimage demands historical knowledge of material predating Kwiatkowski’s article.
O wykazach urzędników sieradzkich, łęczyckich, kujawskich i dobrzyńskich w Metryce Koronnej, ks. 14 i ich datacji raz jeszcze
Authors: Szybkowski Sobiesław
Published: September 2022

The article examines attempts to date the list of Central Polish officials (the Sieradz, Łęczyca, Dobrzyń, and Kujawy areas), given on fol. 211v–212 of the Crown Register (Metryka Koronna – MK) 14 kept in the Central Archives of Historical Records in Warsaw. Sobiesław Szybkowski dated the Kuyawa lists roughly to the years 1480–1484, and the Dobrzyń lists to 1485, with corrections made in them in the years 1491–1494. Janusz Bieniak, on the other hand, dated the original level of the Sieradz, Łęczyca, Dobrzyń and Kujawy lists to the spring or early summer of 1484, earlier additions to the Dobrzyń lists to the years 1485–1489, and later amendments to all lists to the period after 1491. A closer analysis of the external features of the original lists of officials from the areas of Sieradz, Łęczyca, Dobrzyńska, and Kujawy from fol. 2011v–212 MK 14, suggests somewhat different possibilities than before regarding the approximate dating of this important source. It seems that seven hands contributed to its final shape. The first level of the text came from hand no. 1, who planned the list concerning the areas of Sieradz, Łęczyca, Brzeg voivodship (fol. 211v MK 14), and Inowrocław voivodship (beginning of fol. 212 MK 14). It was probably written at the end of 1482 or at the beginning of 1483 (by late spring). The first additions to this list were made by hand no. 2, who also started the Dobrzyń list in free space at the bottom of the first column at fol. 211v. This probably happened in 1485. The next hands, nos 3–7, supplemented and modified the Central Poland lists up to the last years of the reign of Kazimierz Jagiellończyk. Interventions (in the form of deletions) took place during the reign of Jan Olbracht. The annex to the article is a full critical edition of the list of officials of Central Poland from Crown Register (Metryka Koronna) 14.

PRIORITIES OF GENDER POLICIES AND ESG TARGETS IN RUSSIAN PUBLIC COMPANIES’ NON-FINANCIAL REPORTS
Authors:   independent researcher, Zibrova Ekaterina A.
Published: September 2022

The article analyzes the reports of publicly traded Russian companies with a high level of capitalization Sber, Gazprom, Yandex and SIBUR for their gender policy and ESG goals. The incompleteness of non-financial information provided by companies means that when there is information about the ratio of women to men in the company, reports are not an accurate and comprehensive source of understanding how gender policy develops within the company. Reporting Russian public companies are consistent in their history of opening non-financial information, though there is a lack of direct recommendation and instruction from Russia’s adjustment organizations on how to make the process of reporting to be accurate. However, there is a lot of potential for improvement in terms of mainstreaming gender policy priorities and ESG goals: companies do not disclose the full amount of data specified in key documents describing global gender policy priorities; they do not always take into account Russia’s reporting to the UN on the progress of development the 2030 Agenda for Sustainable Development; rarely declare measures to deal with gender inequality issues.

Authors:   Lomonosov Moscow State University, Mankevich Yuliya V.
Published: September 2022

In the year 2015 the document “Transforming the World: An Agenda for Sustainable Development 2030” was adopted. At its core there is the notion of gender equality, which is not only a fundamental human right but also a necessary foundation for peace, prosperity and sustainable development. It is about the need to adjust realized solutions by taking into account the differences between women and men, and recognizing the difference between Millennial Generation Y and Generation Z. Such an approach would eliminate adverse effects and minimize risks. In addition, the possibility of a more efficient use of natural resources is emphasized.
GENDER ASSESSMENT OF THE INSTITUTE OF POLYGAMY (ON THE EXAMPLE OF DAGESTAN)
Authors:   Dagestan Federal Research Center of the Russian Academy of Sciences, Zagirova El’vira M.
Published: September 2022

In the family and marriage sphere of the Dagestan peoples, polygamy was widespread, although it was not a mass phenomenon in the recent past of the history of the peoples of Dagestan. According to the results of the study, it was found that the interviewed Dagestani women categorically do not accept the status of a “second wife” for themselves, moreover, they demonstrate a negative attitude in general to the emergence of the institution of polygamy at the present time. Empirical material shows that the marriage attitudes of the interviewed Dagestani women are not influenced by religion and attitude to religion (believer / non-believer), although Islam allows the possibility of having four wives for a follower of Islam. The author’s hypothesis about the positive attitude and assessment of polygamy by the followers of Islam was not confirmed by the results of the study, what indicates an unwillingness to fully accept the precepts of Islam in the family and marriage sphere. In addition, the survey data show that the interviewed Dagestan population has a negative attitude to the decision of their own children to have a “second wife” and to be a “second wife” with different argumentation.
GENDER SPECIFICITY OF RELIGIOUS BEHAVIOR (ON THE EXAMPLE OF THE DAGESTAN POPULATION)
Authors:   Dagestan Federal Research Russian Academy of Sciences Center, Shakhbanova Madina M.
Published: September 2022

The issue of religiosity and resulting from it religious behavior manifested itself vividly in the post-Soviet period against the background of secularization of Russian society. There is no doubt that religion in society as a whole and in the personal life of an individual plays an essential role, which may be ambiguous in different historical periods. Therefore, the vector of development for religious revival will determine the positive/negative scenario and the climate in society. The marker for diagnosing the religious behavior of the Dagestan population is the content of the concept “true believer”, which defines normative religious practice. Verification of the empirical material shows the existence of certain differences in the attitudes of the interviewed men and women in the designation “a true believer”: the latter focus on the moral and moral attribute, the presence of certain moral properties that allow identifying a person as a “true believer”.

Recent years has witnessed decline in national oil production at an alarming rates of  higher than 10% annually. On the other hand, national gas reserves and production situation  is much better even though problems such as unanticipated production shortfall of  existing fields and commerciality of new reserves have still to be faced. Analysis on history  of production and reserves and comparison between oil and gas discoveries in recent years  may lead into a conclusion natural gas may serve as an alternative source for energy and  national income in years ahead. However, challenges such as technology, infra-structures,  law enforcement, social unrests, tight regulations, and incentives are still day-to-day  reality. These challenges need to be addressed appropriately if sustainable gas, and also  oil, productions are to be achieved.

MODELING OF GRAVITY EFFECTS IN STREAMLINE-BASED SIMULATION FOR THERMAL RECOVERY
Authors: Usman Usman
Published: September 2022

Gravity effects are more prominent in thermal recovery simulations due to larger densitydifference between phases. Historically, the streamline method has been unable toaccount for gravity effects. This is a result of assuming that the fluid path follows thestreamline path and therefore no communication among streamlines. However with gravity,a fluid pathline is different from a fluid streamline. Each phase can move vertically asa result of the gravity segregation effect in addition to the flow along streamline.Gravity effects are accounted in the streamline method by an operator splitting technique.The idea is to isolate the convective flow from diffusion due to gravity for separatesolutions. The convective part is calculated along the common streamline trajectories andthe diffusion part is determined by the direction of gravity. While this has been done successfullyfor isothermal problems, it is still a challenge to obtain both accuracy and efficiencyfor non-isothermal flow. This paper further examines the mixed streamline methodwith an operator splitting technique for this class of problems. The pressure equation fordefining streamlines was derived by summing up the mass conservation equations. Then,the mass and heat transport equations in terms of the streamline time-of-flight coordinatewere solved for each streamline. A gravity step will be followed by solving the segregationequations over the dimensional grid. For simplification of modeling, heat was assumed totransfer by convection only, of which direction is parallel with the flowing phases and theinfluence of temperature in the simulation model is through changes in fluid viscosity only.The proposed approach was tested through simulation of heavy oil recovery by means ofhot waterflooding. The results were verified with those of a commercial fully implicit thermalsimulator.

Doğal Gaz Piyasasında Fiyat Balonları
Authors: ATAŞ Berkan
Published: September 2022

Doğal gaz hem verimliği hem de diğer fosil temelli enerji kaynaklarına göre daha çevreci bir alternatif olması nedeniyle günümüzde en çok kullanılan enerji kaynaklarından biridir. Covid-19 etkilerinin yavaş yavaş hafiflemeye başlaması ile birlikte toparlanan ekonomilerin enerji gereksinimlerinin artmasıyla birlikte gelişen arz talep dengesizlikleri sonucu fiyatlarda yukarı yönlü bir hareket gözlemlenmektedir. Çalışmanın amacı yurtiçi ve uluslararası doğalgaz piyasalarındaki fiyat balonlarını pandemi öncesi yakın dönemi de kapsar şekilde karşılaştırmalı olarak analiz etmektir. Fiyat balonlarının tespiti için Generalised Supremum Augmented Dickey Fuller (GSADF) yöntemi kullanılmıştır. Bulunan sonuçlara göre hem yurtiçi gaz referans fiyatında hem de uluslararası doğal gaz piyasında çok dönemli fiyat balonu bulgularına rastlanmıştır. Bununla birlikte uluslararası ve yurtiçi piyasadaki balonların büyük ölçüde birbirine yakın dönemde gerçekleşmesi yurtiçi fiyat politikalarının uluslararası patlayıcı fiyat değişimlerini sönümlendirmekte yetersiz olduğunu göstermektedir.

Masonry is one of the oldest materials that humans use for construction. It is durable, as seen on ancient structures built thousands of years ago, yet still in excellent shape. Recently, masonry walls have struggled to be competitive among other construction materials such as precast concrete, tilt-up walls, timber, etc. This is mainly due to construction practices and the lack of a standardized modular masonry system that prevents offsite construction. In this paper, new construction methods for concrete masonry walls are proposed. These methods are based on building partially grouted masonry panels that can be built onsite or offsite, then transported and assembled on the site. The methods commonly use a restrained unbonded post-tensioned (UPT) threaded bar to join panels. A full-scale experimental program campaign at the University of Alberta (UOA) is currently undergoing to test the proposed methods. Numerical models were developed before the experimental investigation to assess the behaviour of such techniques under out-of-plane loading. Bare joints, connecting panels reinforcement, and grouting joints are the three types of panel connections proposed here. The influences of the magnitude of prestressing and lateral restraints stiffness are also studied. The results show that the proposed approaches are comparable to traditionally constructed walls with improved serviceability. Also, because of the relative ease of construction and improved post-cracking behaviour, connecting panel reinforcement is the preferred method. Whereas the increasing level of prestressing enhances service conditions but leads to premature failure. Also, lateral restraints with high stiffness, such as grout or steel, are essential to enhance post-cracking behaviour.

Although Modular Construction (MC) is already known in Brazil mainly to due the fast construction of health facilities during the Covid 19 pandemic, very few developers and building companies have adopted it as an ordinary strategy. Previous studies do not focus on analysing how start-up companies can contribute to MC establishment in the country. This study aims to describe the journey of a local start-up company in adopting MC following a descriptive case-study approach. The findings suggest that the following drivers are crucial for the survival and success of a start-up MC company (i) the development of a variety of products that fits market segments and ensuring a minimal sale revenue regularly to pay fixed costs until it manages to capture investment to scale its business; (ii) taking into consideration it takes time and practice first on a smaller scale before going to larger projects, and multi-story modular buildings; (iii) training of skilled professionals and education on design and detailing on MC building technologies; (iv) standardization of building components, product and design to certain levels is inevitable.

Worksite communication is a key to boosting teamwork and improving worker performance on the construction worksite. Communication among workers on the construction site mostly consists of speech communication. However, construction sites are typically noisy due to construction tasks like drilling and operation of heavy equipment. Meanwhile, workers on construction sites typically represent a range of different ethnic and linguistic backgrounds and have different speaking accents. This can make it difficult for the listener to understand the speaker clearly, leading to miscommunication and errors in decision making on the construction site. Technological advancements in recent years can be leveraged to mitigate this problem. In this paper, a keyword identification framework is developed for speech communication on the construction site. For this framework, 12 hours of raw audio data containing 18 crane signalman speech commands (referred to as “keywords”) are collected. The crane signalman uses specific keywords to communicate with the crane operator and guide the crane operator in the crane operations. The 2-second audio clips (this being the approximate duration of each keyword) are extracted from the raw audio dataset, and construction site noise is added. Moreover, mel-frequency cepstral coefficients are extracted from the waveform audio dataset. The extracted mel-frequency cepstral coefficients, in turn, are used to train the 1-dimensional convolutional neural network. After training, the model is found to achieve a training accuracy of 97.3%, a validation accuracy of 96.1%, and a testing accuracy of 93.8%. The model is further deployed for real-time identification of keywords in speech, with the model achieving an accuracy of 95.3%. In light of these findings, it can be concluded that the developed framework is suitable for real-time application in noisy construction sites for identifying specific keywords in speech.

The construction industry's lack of materials, resources, and financial assets streamlined a shift toward using digital lean principles to obtain precise management over the limited resources. Steel fabrication companies rely heavily upon the enormous equipment to get promising results.  However, implementing lean principles in the fabrication process is not straightforward due to the non-repetitive nature of steel construction products. Hence, the time-based modeling for such a process lacks accuracy and reliability, especially for manual steel fabrication processes.  Accordingly, the current study aims to achieve a practical and accurate estimation of fabrication time aspects.  This study targets modeling manual steel fabrication processes (fitting and welding workstations) in terms of processing times (cycle time and value-added time). The proposed approach builds a machine learning (ML) model to estimate the identified processing time aspects. For performance assessment, the typical correlation analysis and linear regression (LR) approach was used as a benchmark to quantify the ML model's pros and cons in terms of practicality and accuracy. The required data source for this study is a steel fabrication industry partner. The results of this study show ML superiority in accuracy over LR processing time predictive models, particularly when predictive parameters increase ML presents a 13.2 % improvement in mean squared error compared to the LR predictive model. LR models need fewer data and are not computationally expensive like ML models, making them more practical. Additionally, the study introduces a precise and practical time estimation approach. Such an approach provides precious input for simulation models which support evidence-based decisions and benefits quantification of plans.

With the enormous population growth in the last few decades, there is a demand for infrastructure development and rapid urbanization that result in the depletion of natural resources, emission of greenhouse gases, and subsequently, exacerbation of the climate crisis. Moreover, waste materials generated by different industries such as the construction industry end up by burning or dumping them in landfills further posing serious health hazards. Besides, skyrocketing prices of housing and limited income of major population groups have resulted in the housing crisis. Therefore, it is imperative to find low-cost, environment friendly and sustainable solutions to mitigate aforementioned problems. The literature indicates that the modular construction method could be a viable solution that can reduce waste generation and construction costs. This method has been extensively used in many parts of the world in different applications mostly in the construction of low-rise buildings. However, with the advent of technological advancement in the construction industry, studies have shown that modular construction can also be successfully employed for medium and high-rise buildings. This paper presents a holistic review of the existing literature on the development of modular wall panels to foster sustainability and alleviate the housing gap. To this end, a proactive approach has been undertaken to identify key research areas to study the use of waste materials in the development of modular wall panels. The results of the literature review revealed that modular wall panels have the potential to substantially reduce the construction cost and carbon footprint. The barriers to the growth of modular construction were also discussed in this paper.
