Authors: M Abdul Aziz , WS Wan Ismail , N Bahar , R Mahadevan , S Azhar Shah
Published: November 2020

Introduction: Internet addiction is becoming a global problem and has been associated with mental health issues such as depression and anxiety. There is a strong need for local research, given the recent rise of mental health issues amongst children and adolescents in Malaysia, as well as lack of research in this field locally. Methods: This study assessed the prevalence of internet addiction, and its association with internetrelated factors, depressive symptoms, anxiety symptoms, and self-esteem, amongst selected secondary school students in the Klang Valley, Malaysia. In a cross-sectional study, 199 adolescents were conveniently chosen from six randomly selected secondary schools within Klang Valley. Subjects completed a demographic questionnaire, as well as Malay versions of the Internet Addiction Test (MVIAT), Children’s Depression Inventory (CDI), Depression Anxiety Stress Scales-21 anxiety subscale (DASS-21) and Rosenberg Self-Esteem Scale (RSES). Multiple logistic regression analysis was carried out. Results: This study found that 49.2% of students were addicted to the internet. Significant factors associated with internet addiction were spending longer hours online during the holidays (OR 1.20, CI 1.01-1.35), easy access to a computer (OR 4.01, CI 1.50 - 10.76), confiding on the internet (OR 4.07, CI 1.49-11.13), severe level of anxiety (OR 3.63, CI 1.04-12.73) and high depression scores (OR 1.10, CI 1.01-1.20). Contrary to previous studies, self-esteem was not found to be significantly associated with internet addiction. Conclusion: This study has important implications in relation to clinical practice, research, and policy-making in Malaysia.

Introduction: Good control of glycaemia negates potential maternal and fetal complications. A diet suitable for women with gestational diabetes mellitus (GDM) is a first line approach. However, little is said about suitable exercise in pregnancy that will potentially help control glycaemia. This pilot study seeks to understand the perceived barriers to exercise in women with GDM. Materials and Methods: This crosssectional study recruited patients with GDM on diet control at the antenatal clinic of Hospital Sultanah Aminah Johor Bahru, Malaysia between October 2017 and January 2018. Those who fulfilled the recruitment criteria were approached and 89 women consented to participate. Data was obtained from antenatal records and a self-administered questionnaire. Results: The mean age of the participants was 33.3 years. More than 80% were Para 1 and above. 69.6% were either overweight or obese at booking of pregnancy. 80.9% were aware that exercise was necessary for women with GDM. Only 6.7% say that healthcare professionals were their source of information on exercise in pregnancy. 77.3% of the women with low physical activity had full time jobs. Housewives (64.5%) had the highest level of physical activity. Tiredness (43.8%), childcare duties (38.2%) and lack of time (27.0%) were the most common perceived barriers to exercise. Nulliparity was significantly associated with tiredness. Conclusion: Main barriers to exercise are tiredness and childcare duties. Health care professionals did little in educating women with GDM on suitable exercise.

The article describes the Project, aimed at supporting a diverse group of the participants in their learning with the help of such Massive Open Online Courses (MOOCs) as English for Media Literacy and English for STEM and organized by Teachers of English Association of Kazakhstan (KazTEA) and the Regional English Language Office of the U.S. Embassy in Nur-Sultan (RELO). Amongst the project participants were students and teachers from all over Kazakhstan, including Karaganda, Almaty, Atyrau, Kyzylorda, Shymkent, etc. Foreign language skills among the participants ranged from beginner to advanced levels. To help adapt to the Courser's platform, ensure the maximum involvement of the participants, their cooperation, and mastery of new competencies in each group, a facilitator teacher, whose role was in contrast to a regular teacher, was involved. This project was the first, in which the main tasks and the principle of the facilitator's work were gradually clarified and defined. The experience gained helped to describe in detail the functions of the facilitator, their difference from the generally accepted ideas about a teacher-leader. Thanks to the facilitators’ sessions, all participants successfully completed both courses and later used the platform to proceed with other courses in their professional areas and interests.

Authors: Gomes da Silva Jonas
Published: November 2020

After 265 days, since the first reported case of Covid-19, the world has reported the lost of almost one million (969.018) precious lives (WORLDOMETERS, 2020). The pandemic is a challenge for all countries, most of them eager to learn from nations that are successful against the virus. In addition, an international survey, published on April/20, by Silva (2020, p. 600), concluded that although no country is prepared to face epidemics and pandemics (NTI, JHU, and EIU, 2019), among the 16 countries investigated, Thailand, Finland, Australia, South Korea, Denmark, and Sweden are cases that Brazil could study so as not to repeat the scenarios of China, USA, Italy, and Spain. Thus, this study investigates the performance and the best management practices adopted in Thailand to save lives against Covid-19, during the first 180 days facing the pandemic. The research is useful for academy, government policymakers and authorities. It is descriptive, with the application of an online questionnaire, bibliographic and documentary research, involving the study of official sites, articles, reports, manuals, and other technical documents. A new indicator was developed (Fatality Total Index), which allowed to identify that among 20 nations with the highest number of fatal cases, the ten most critical are 1st) Mexico; 2nd) Peru; 3rd) Italy; 4th) Ecuador; 5th) Iran; 6th) Chile; 7th) UK; 8th) Belgium; 9th) Colombia; and 10th) Brazil. Some conclusions are: first) Thailand`s FTI180 is the very low, indicating that this country has learned from the lessons of the past, reason by which is the best at saving lives against the Covid-19; Third) for 86 respondents living in Thailand, wear mask, not shake hands, not hug in public, wash hands, and not wearing shoes in the house, were the five most decisive cultural practices that saved lives; Fourth) For 96 respondents living in Thailand, the ten main policy measures adopted by Thailand Government that saved lives against the Covid-19 are: first) international travel control; 2nd) public event cancellations; 3rd) schools closures; 4th) restriction on internal movement; 5th) workplaces closures; 6th) public information campaigns; 7th) effective public-private collaboration; 8th) increase the medical and personal equipment capacity; 9th) support the expansion of testing system, and 10th) wage subsidies for workers; Fifth) to save lives against Covid-19, 28 innovative products or services were identified in Thailand, with majority led by Corporations, Universities, followed by Public Sector, Start Ups, and Others.

Authors: Da Silva de Souza Diego , De Souza Silva Paulo , Barbosa de Alencar David
Published: November 2020

The general objective of this article was to promote through bibliographic studies the two types of lamps, in addition to the comparative analysis of compact fluorescent lamps versus LED lamps: an economy factor. The specific objectives were: - to explain the conceptual precepts on: lighting engineering, definitions, characteristics, invention, operation, defect, quality and the environments used and the NBRs regulations; - address the economic impact generated by the choice of LED lamps and compact fluorescent lamps; - emphasize on an economic feasibility study on the use of LED lamps and compact fluorescent lamps. The justification of the study is related, in the promotion regarding the use of LED lamps and compact fluorescents, in the factor that generates savings. Since the areas related to artificial lighting are responsible for a significant portion of energy demand, both on a large scale - such as lighting for public roads or industrial buildings - and on smaller scales - in commercial and residential buildings. Therefore, its promotion is crucial in the context of economic viability. The lamps provide the luminous energy, through which a better luminous efficiency is obtained. Currently, there are several types of lamps available, different in several aspects: luminous intensity, reproduction colors, energy efficiency, physical composition, method for emitting light, specific purposes, prices, among others. It is worth mentioning that the lamps differ from each other not only by the different luminous fluxes that they radiate, but also by the different powers they consume. In order to compare them, it is necessary to know how many lumens are generated per absorbed watt. This greatness is called energy efficiency. Thus, the proposal of a study was evidenced, in order to promote these luminous resources, in addition to emphasizing their economic viability.
The Influence of Background Music Teaching on Accuracy and Fluency of Freshmen ’s Oral English in China
Authors: Song Yanbei
Published: November 2020

Many students like listening to music through mobile phones or computers when they are studying after class. Some students stated they were more efficiency when they were studying with the background music;some claimed they were distracted by the background music.In English teaching, students tend to have anxiety due to various subjective and objective reasons. If students are too anxious, it will affect their oral performance, especially accuracy and fluency. Therefore, to help students improve their oral English, we need to help them overcome their anxiety. In oral English teaching, an effective way to relieve students’ anxiety is to play background music. Because the musical background helps to create a relaxed atmosphere in which anxiety and tension are relieved and attention to the new content is aroused. The paper studied the influence of background music teaching on accuracy and fluency of freshmen’ s oral English. The results were in the following: 1). Background music teaching did not facilitate clear effect on oral accuracy of college students. To be specific, background music teaching only could help to reduce the rate of students’ pronunciation error. In terms of syntactic errors and self-repair, the traditional teaching has decreased more than background music teaching. Background music teaching did not help to reduce lexical errors. 2). Compared with traditional teaching, oral fluency in background music teaching has not improved significantly. 3). This research results challenged the traditional idea that background music could achieve better teaching effect. Although background music might reduce the pressure and relieve the atmosphere, it could not help students to acquire more comprehensive input. Students need more quiet teaching environment and relevant module training, especially the flexible use of vocabulary, are needed to improve the accuracy and fluency of students’ oral English to a greater extent.

Introduction: The family and reproductive planning program is offered in the instances of the Unified Health System (SUS), and makes free contraceptive methods and devices available to the entire population, seeking to make people aware of the advantages and disadvantages of each method. Despite citizens' rights, some communities live in a situation of vulnerability and have greater difficulty in accessing public services, as in that program. Objective: To analyze the knowledge and adherence of women to the family and reproductive planning program and contraceptive methods, in addition to carrying out health education activities on the subject, focusing on the copper IUD. Methodology: This is an action research, with random sampling and a quantitative-descriptive approach for data analysis and description. The target population is made up of women of childbearing age, or who have already started sex. The collection was carried out in the field by means of a questionnaire prepared by the researchers based on a literature review. Results: 195 (98%) women reported not knowing the reproductive planning program and, of these, 116 (59.5%) had at least one unwanted pregnancy; The contraceptive method of most frequent choice among women is ligation, of the 200 women 60 (30.5%) opted for it; and 30% of the population has had at least one abortion in their lifetime. Conclusion: There was little knowledge and low adherence to reproductive planning and contraceptive methods in this population, possibly due to the segregation of low-income, mixed-race and black women, with low education, who are marginalized, suggesting difficulty in accessing health services, lack knowledge and family structure, in addition to demonstrating gaps in the health system.

Published: November 2020

The disadvantage of using the digital antenna focusing (DAF) method to obtain an image of reflectors is a large volume of echo signals and an insufficiently high speed of their registration. To increase it, it is proposed to simultaneously emit sounding pulses by all elements of the antenna array (AR), formed by the sets of code sequences used in the Code Division Multiple Access (CDMA) technology. The measured echoes can be decoded using matched filtering (CF) and the reflectors can be reconstructed using the combined SAFT (C-SAFT) method. The image can be restored without decoding the measured echo signals by the ME method. The proposed technology was tested to obtain images of reflectors in samples of duralumin, steel 20 and steel 40.

Every industry has an impact on the environment, either good or bad, and leather and footwear industries are no exception. For the footwear industry, the main environmental impacts are the releasing of volatile organic compounds (VOCs) and solid wastes. The pressure of reducing harm to the environment is coming from both the consumers and the legislation. CO2 and VOCs are hazardous to human health and also trigger serious environment problems, such as ozone layer depletion, offensive odour, photochemical smog, acid rain and many others. Adhesives, finishing products and cleaners contribute to VOCs emissions in the footwear manufacturing industry. VOCs emission may also arise from primers, separating agents, printing inks or finishing pastes. Some most commonly produced VOCs in the footwear manufacturing industry are benzene, toluene, styrene, ethylene, xylene, acetaldehyde, formaldehyde, methyl ethyl ketone, chlorobenzene, phenol etc. All of these cause severe health problems in humans and have an adverse effect on the environment. An increasing number of footwear factories adversely affects the environment and human health. One of the largest environmental impacts of shoe industry comes from the manufacturing stages of the shoe’s life cycle. This study was carried out to measure the carbon footprint and VOCs emissions among ten selected footwear factories. The results revealed that the total energy footprint for one pair of shoes is 18.004826 MJ, the water footprint is 8.37167 litres and the carbon footprint is 9.174979 kg CO2 eq. The highest impact in terms of the carbon footprint lies in the shoe manufacturing process with a 5.85109 eq. CO2 (kg). The total VOCs consumption for a fashion shoe is around 36.5 g/pair on average. There should be an initiative taken with the aim of adjusting the choice of methods, materials, machines and the monitoring systems as well as the safety policy for the workers and the environment.

Published: November 2020

Introdução: A microcefalia e a microencefalia que lhe está associada pode ter início intrauterino ou pós-natal. A etiologia é diversa, englobando doenças genéticas, metabólicas, infeções intrauterinas ou exposições ambientais, exigindo uma abordagem diagnóstica específica. Descrição do caso: Apresenta-se uma lactente de 10 meses, com história de restrição do crescimento intrauterino, microcefalia, atraso do desenvolvimento psicomotor e dismorfias faciais. A mãe evidenciava atraso intelectual e tinha outro filho com microcefalia e atraso do desenvolvimento psicomotor. Suspeitou-se de um fator materno na génese deste quadro. Os níveis séricos maternos de fenilalanina foram compatíveis com o diagnóstico de fenilcetonúria clássica, identificando-se a síndroma de fenilcetonúria materna. Comentário: Níveis séricos elevados de fenilalanina durante a gravidez são teratogénicos para o feto e associam-se a restrição do crescimento intrauterino, microcefalia, cardiopatias congénitas, dismorfias faciais, atraso de crescimento pós-natal e atraso do desenvolvimento psicomotor. Esta embriopatia pode ser prevenida pela restrição dietética de fenilalanina, iniciada antes da conceção e mantida na gravidez.
Camptocormia: um relato de caso bizarro e a sua adequada referenciação
Authors:   Médico de Família, Hernâni-Eusébio Jorge , Silva Ricardo Jorge ,   Médico de Família, Machado Álvaro ,   Médico de Família
Published: November 2020

Introdução: A camptocormia (flexão anterior da coluna toraco-lombar) é um diagnóstico secundário a causas neurológicas (particularmente à doença de Parkinson), causas ortopédicas e outras (intoxicação farmacológica e síndromas paraneoplásicos). Quando associada a doenças neurológicas, esta reverte integralmente se o utente assumir o decúbito dorsal, o que não se verifica quando a causa é ortopédica. Este achado puramente clínico é fulcral para a referenciação de um utente da forma mais correta e tomada de decisão sobre o plano a adotar. Descrição do caso: Homem de 65 anos, sem antecedentes de relevo ou uso de medicação habitual. Observado em consulta de neurologia, entrando no consultório com marcada flexão anterior da coluna toraco-lombar (camptocormia). O utente foi previamente orientado pelo médico de família para consulta de ortopedia por esta queixa, com imagiologia de achatamento em cunha da vértebra T12. Também acompanhado por medicina física e reabilitação que, após tratamento fisiátrico, o referencia à neurologia por suspeita de causa neurológica da camptocormia. Ao exame objetivo apresentava camptocormia marcada que não revertia no decúbito dorsal. Sem tremor, rigidez, discinésia ou outros sintomas extrapiramidais. Sem incontinência esfincteriana. Comentário: A referenciação de casos de camptocormia pode ser complexa, permitindo a abordagem holística do utente compreender a sua globalidade e a dos seus sintomas, ponderando os achados indicativos da causa primária do problema. Neste caso, a não reversão da camptocormia com o decúbito dorsal, a ausência de tremor/sintomas extrapiramidais e a documentação imagiológica de possível causa ortopédica tornam a referenciação à consulta de neurologia menos pertinente que a referenciação feita pelo médico de família para consulta de ortopedia. Podemos, assim, gerir de forma mais profícua a situação do utente e as suas expectativas quanto à resolução do problema. Foi dado pelo utente o consentimento informado, livre e esclarecido para a recolha de dados clínicos e imagens fotográficas, assim como para publicação.

Authors: Do Minh Phuong , Ignatov P. A. , Phan Thi Hong , Nguyen Duy Hung , Tran Duan
Published: November 2020

Background. Complex Au-Cu-U mineralization is found in the metamorphic rocks of central Vietnam in the zones of their contact with Triassic granite intrusions. It is localized in tectonic breccias and cataclasites, which affected Triassic granitoids and Precambrian metaskarn rocks. The greatest differentiation is observed for tectonically disturbed granites of the Hai Van complex and the metasomatically reworked zones of contacts of this complex with metacarbonate and metaultramafic rocks of the Kham Duc complex.

Aim. To determine the mineral and elemental composition of complex occurrences of Cu, U and Au in Proterozoic rocks of the Kon Tum province of central Vietnam.

Materials and methods. The work was based on the authors’ data obtained during fieldwork and analytical laboratory studies in the 2016–2019 period. The diagnostics of ore mineral composition was carried out using 60 polished sections. The chemical composition of ores was determined for 214 samples by ICP MS and for 374 samples by atomic absorption spectrometry at the Vietnamese Centre for Geological and Experimental Analysis in the city of Hanoi. The geochemical relationships of ore components were established by the method of multivariate statistical correlations.

Results. The mineral composition includes pyrrhotite, pyrite, chalcopyrite, molybdenite, magnetite, martite, hematite, cubanite, marcasite, gold, xenotime, sphalerite, uraninite, chalcocite, covellite, goethite, malachite and limonite. According to the petrographic and petrochemical composition, the geological position and the data on isotopic age, the metamorphic formations of the Kham Duc complex can be considered as Neoproterozoic-Cambrian formations having experienced metamorphism in the Ordovician.

Conclusion. A scheme of the sequence of mineral formation was outlined. ICP MS results of primary ores showed that, in addition to Cu, the formations under study contain concentrations of Co, Mo, U, Au, Zn, Ni, V, Y, La, and As. A positive correlation was found between Cu, U and Au. A model of hydrothermal ore formation was proposed.

Published: November 2020

Background. Large-scale geological structures, such as lineaments, are of great research interest due to their potential to mark the presence of ore fields.

Aim. To determine the relationship between ore deposits, lineaments and large-scale faults in Iran using satellite imagery, digital relief modelling and structural mapping.

Materials and methods. In this study, we compiled a map of lineaments in the Iran, which were determined both automatically and manually. A database of the distribution of ore deposits and lineaments was compiled from available maps, publications and reports on ore deposits in Iran. These maps were overlaid to study the relationship between the locations of the lineaments, faults and ore deposits.

Results. An analysis of the lineaments revealed on geological maps indicates the presence of four dominant strike directions of large and small lineaments. The developed lineament map shows the main northwest trending longitudinal faults, which are parallel to the main strike of the Zagros orogenic belt; sublatitudinal and submeridional trending oblique faults; northeast trending transverse faults. A “Combined map of lineaments and deposits of copper, lead, zinc and iron in Iran” was compiled by the ArcGis software using maps of lineaments and mineral deposits. The ore deposits identified were analysed to determine the distribution of the distances between each deposit using the counting and cumulative methods the ArcGis software.

Conclusions. About 90% and 50% of ore deposits are located at a distance of less than 15 km and 5 km, respectively, from the centre line of the associated lineament. A direct relationship between the density of lineaments and the presence of deposits was observed. The obtained results demonstrate the potential of this method for assessing the prospects of ore fields in hard-to-reach and poorly studied regions.

A computer network is the infrastructure that allows two or more computers (called hosts) to communicate with each other. The network achieves this by providing a set of rules for communication, called protocols, which should be observed by all participating hosts. The need for a protocol should be obvious: it allows different computers from different vendors and with different operating characteristics to ‘speak the same language’. Communication protocols are formal descriptions of digital message formats and rules. They are required to exchange messages in or between computing systems and are required in telecommunications When two computer system (server and client) communicate with each other they may encounter data loss due to many obstructions like thick walls,jammers etc. these may cause the data packets to be lost while transmission. We used a protocol to minimize or avoid this loss. This can be done by intelligently routing the data packets via paths that are not jammed and time effective as well.If the messages or data packets are not delivered to the receiver the protocol will resend the data packet. If there is traffic means data packets are delayed due to some obstacles then the server will choose feasible route to deliver the data packets. We use random linear network coding (RLNC) based scheme for multipath communication in the presence of lossy links with different delay characteristics to obtain ultra-reliability and low latency. A sliding window version of RLNC is proposed where the coded packets are generated using packets in a window size and are inserted among systematic packets in different paths. The packets are scheduled in the paths in a round robin fashion proportional to the data rates. We use finite encoding and decoding window size and do not rely on feedback for closing the sliding window. Our implementation of two paths with LTE and WiFi characteristics shows that the proposed sliding window scheme achieves better latency compared to the block RLNC code. It is also shown that the proposed scheme achieves low latency communication through multiple paths compared to the individual paths for bursty traffic by translating the throughput on both the paths into latency gain.

Timetable generation is a complex job for the administration in terms of time and man power. The system proposed will help to generate it automatically thus saving time. It prevents the complexity of setting and managing Timetable manually. Different algorithms like genetic, heuristic, resource scheduling are used to minimise difficulties faced during generation of timetable. These algorithms consist of a numeral of strategy, aimed to improve the cooperativeness of the search operation. The system will take various inputs like number of subjects, professors, workload of a teacher, semester. Depending on these inputs, timetables for working days of the week for teaching staff will be generated. This will integrate by making optimal use of all the resources in a way that will best suit the constraints.
Improvement of Family Care Ability for Elderly with Depression through Psychoeducation Intervention Program
Authors: Riasmini Ni Made
Published: November 2020

The increase in the incidence of depression in the elderly can affect the elderly and their families' quality of life. Depression in the elderly is mostly caused by a lack of knowledge, attitudes, and family behavior caring for the elderly. It has an impact on the increasing cases of older people with depression in the community. To prevent increasing depression cases, it is necessary to empower family potential and social support. This study aims to obtain a description of the Psychoeducation Intervention Program (PIP) on families' ability to care for older people with depression in the community. The research method used is a Quasi-experiment with control group design. The sample is families who have elderly with depression by screening using the Geriatric Depression Scale Short Form (GDS-SF). The number of samples was 68 for the intervention group and 68 for the control group—statistical test using dependent t-test, independent t-test, and Mancova test. The results showed an increase in knowledge, attitudes, and family behavior in caring for the elderly before and after PIP. There were differences in the family's ability to care for the depressed elderly between the intervention and control groups. The resulting psycho-educational intervention program can serve as a basis for policymakers and health service managers to carry out various interventions related to family empowerment.
Change of Bike-share Usage in Five Cities of United States during COVID-19
Authors: Tokey Ahmad Ilderim
Published: November 2020

This study explores how bike-share usage varied over the six months of the coronavirus pandemic (March’20-August’20) in five US cities. First, it finds that in most of the months, the changes (both increase or decrease) of bike-share usage from the preceding months are significantly higher in central tracts than peripheral tracts. This finding has more statistical significance for cities that are popular for biking (e.g. DC, Boston, Portland). Second, biking is found to be positively associated with cities’ non-work trip rate and people’s COVID exposure and it was diminished with more people maintaining social distance and staying at home.

Social problems among students are to be observed as getting serious. Due to this, one question related to social and disciplinary problems has been brought up – how far have students learn to internalise and practise good values in their lives. Hence, this article presents findings related to internalization of good values ​​in current scenario among secondary school students. This study used a descriptive survey research design. Data collected through the questionnaire survey involving secondary school students selected in Peninsular Malaysia and supported by semi-structure interview data. The results showed that the overall internalization of good values ​​were at moderately high level. This study found that only three dimensional values ​​that indicate a high level of internalization. The good values are the value of gratitude, patriotism and the value of respect. The 14 dimensional values ​​indicate a moderately high level of internalization. Among these values, the lower is the value of independent, community spirit and the value ​​of diligent. In conclusion, some implications of the study are discussed in this paper in order to develop student’s values.

Published: November 2020

The paper deals with the issue of supporting public passenger transport and integration in order to ensure the sustainable mobility of population. It highlights the importance of public passenger transport and the reasons why the population prefers cars. The objective of the paper is to analyse public passenger transport without mutual integration of individual transport systems resulting in the fact that it is not sufficiently able to compete with individual automobile transport. It is suggested the process of public passenger transport integration as well as the design of key elements in order to increase road safety. In addition, the paper confirms the hypothesis that by supporting of public passenger transport and increasing the number of individuals transported by public passenger transport, road safety increase can be achieved.

cultural hybridization of digital society
Authors: Plenković Mario , Mustić Daria
Published: November 2020

The paper is analyzing basic operative terms of visual communication in contemporary digital media environment, which determinates analytical units of media communication and the new culture of communicating and message dissemination. Theory discussion is conducted by diachronic and synchrony analysis of elements of visual communication in digital environment and theory of public action. The main goal is to establish new communicative paradigm of media communication which includes the evaluation of digital skills, media literacy and the characteristics of the new hybrid dig-ital society. Authors observe modern media communication and visual digitalization, not only in technical sense of transmission and adjustment of analog signal into digital signal, but also, simultaneous development of digital culture and adaptation of media content, media production and distribution of content to the new web environment (Web 2.0, Web 3.0, Web 4.0 and theoretical possibilities
of so called Web 5.0) de-riving the new contexts of social power.

Authors: Kumar Rajendra , Mokashi Uma Mohan
Published: November 2020

The authors attempted to investigate how to resolve the growing work-life balance issue occurring due to COVID-19 Pandemic in the higher education sector. On the premise of prominent literature, the study conceptualized a framework to test if supervisor support and employee`s proactive work behavior could help address the work-life balance issue. Through applying the quantitative approach, the study collected data from employees working in a higher education institution in the UK. Results of the structural equation modeling found significant association and influence of supervisor support and work-life balance. The study also found a strong affiliation between proactive work behavior and work-life balance. However, proactive work behavior did not moderate supervisor support and work-life balance relationship. The study concluded that both supervisor support and proactive work behavior could be vital in helping employees to achieve their work goals effectively and efficiently without compromising their work-life balance. The study forwards prominent implications to guide practitioners, policymakers and researchers in this domain.
