Smart City governance from below: how Hungarian towns respond to the need for institutional design and digital capacity building
Authors: Kaiser Tamás
Published: July 2020

One of the most important focal points of the complex processes taking place in the world has been created by highly diverse urbanisation zones, which all face similar problems. At the same time, for historical, economic and cultural geopolitical reasons, each town needs an approach that is tailored to its specific characteristics and needs. However, relatively little attention has been paid to developing the elements of a supportive environment, the process of planning and capacity-building needed to manage a smart city, and exploring concrete cases and best practices. This study examines initiatives supporting the conditions for smart city governance within the framework of the Digital Welfare Programme (DWP) launched in Hungary, with particular focus on the development of a marketplace as an info-communication platform to support the planning process.
E-Cohesion: E-Solutions in the implementation of combined financial instruments
Authors: Nyikos Györgyi , Hajdu Szilvia , Laposa Tamás
Published: July 2020

Europe is facing an investment gap and the so-called financial instruments seem to be one of the solutions. They invest public sources on a repayable basis with a revolving character, which allows for a much greater efficiency in the allocation of public capital and the long-term sustainability of public investment. Policymakers see considerable value in supporting the further development of FIs and their use in both existing and new policy-related areas of activity3. The combined-credit is a unique financial development tool where credit and non-repayable assistance can be requested within a single financial product. [10,13]
The paper analyses the Hungarian practice using this special financial instrument with the application of information technology, both looking at the empirical evidences and seeking for an answer to the question, whether the combined utilization of financial instruments and grants is effective, useful or not, and how the different IT solutions could affect the efficiency of this financial product.
It is argued in this paper that the utilization of information technology can significantly improve the effectiveness of using financial instruments. This paper has three main aims: first, to review the legislation and the approach of Member States on the utilization of financial instruments; second, to analyse current and previous forms of IT support and their impact on the efficient utilization of the above instruments; third, to make proposals for further research on the e-government-based utilization of financial instruments.
An evaluation of an implementation of electronic document management in the Ostalb-county of Baden-Württemberg
Authors: Pahnke Dana-Maria , Kőnig Balázs , Müller-Török Robert
Published: July 2020

Whilst most of the literature on electronic document management in public administration focusses on the implementation, papers on evaluations after the implementation are quite rare. Some years ago, this electronic way of administration has been implemented at job centers run by the Ostalb-County (Federal State of Baden-Württemberg, Federal Republic of Germany); so an impartial evaluation was on the agenda. That particular Electronic Document Management, which by 2020 will become mandatory within the public administration of Baden-Württemberg, is a huge step towards a transparent, effective and customer-oriented public administration in the 21st century. Although, it is also obvious, that it is not a "sole remedy", and it is not good for anything on its own, without other aspects, like user awareness and user readiness, it is still a great technical asset. The current paper is mostly based on empirical analysis - except for the introduction of the technological, management and legal background, and connecting fields, like the relevant pieces of EU-regulation, and issues of data security. The assessment was done by staff of the Job Centers of Ostalbkreis, who were interviewed in extensio, so the article is in an overwhelming part based on primary data. This is why the reader will encounter only a few references to the otherwise vast professional literature of the topics involved. The interviews and the assessment carried out by the staff, have been digested in the bachelor thesis of the lead author, Ms. Pahnke. Hence valuablelessons learnt can hopefully be derived from this contribution.
Living labs - instruments of social innovation in rural areas
Authors: Tirziu Andreea-Maria , Vrabie Catalin
Published: July 2020

In a country where nearly half the population lives in rural areas, it is difficult to link concepts such as smart cities, Internet of Things to the local government’s priority list. However, lately there have been numerous initiatives to improve access to information using ICT in the rural communities as well. The purpose of this article is not to exhaustively measure the already adopted means, but merely to provide a series of items retrieved as barriers to ICT projects meant to develop these communities. Following the studies conducted so far (in Romania there are about 2,700 communes – the lowest administrative entities of our country), it was observed that the digital divide is found in 100% of these areas. At the urban level – especially in the big cities, pilot projects for developing digital literacy among the elder population had a relatively high success. Such programs have been initiated at the level of the communes whose living standard is higher (the ones that are located near large cities). Their successes, though certainly less visible than in the urban communities, are noteworthy. Most such programs have targeted educational and health fields. The article we propose aims to show these programs’ implementation degree in Romania, providing as examples the most successful cases that help the social innovation process. The intention with which we start this study is to create a list of objectives that the initiators of these programs have to take into account during the preparation of those programs.
The best practices of online presidential communication in democratic states Romania, Republic of Moldova and Russian Federation
Authors: Rusu Liliana
Published: July 2020

The Presidential Communication is defined as the dissemination, by the president or the presidential institution, of the public or national interest information. The interactive model, with its connotation of public deliberation renovated form, is the most egalitarian and democratic model of presidential political communication.
Currently, in most European democratic states, the "true public deliberation" is favored by political websites which allow the two-way communication and the three-way communication. Among the most interactive elements of the websites the researchers have identified the following: active email to political leader or contact forms, e-subscriptions, forums, site search engine.
Presidency website is the main form of new media involved in the presidential political communication of the Republic of Moldova. Mapping the website, content analysis, interpretation of results - are the methods which have been used for the purposes to assess the effectiveness of communication between Head of State and citizens from the online environment. Contrastive analysis of new media, applied for the presidential communication by Nicolae Timofti, Klaus Iohannis, Vladimir Putin, has served to determine the best practices and to develop recommendations for optimizing online presidential communication of the Republic of Moldova.
Voting advice applications in Hungary. Vokskabin in the multi-election year 2014 and beyond
Authors: Barlai Melani
Published: July 2020

The objective of the paper is to introduce the first Hungarian scientifically developed online voting advice application project Vokskabin (www.vokskabin.hu). It was established on the occasion of the Hungarian super election year 2014, when three elections - parliamentary, the European Parliament and the municipal elections – took place. As a first step the study describes the development phase of the project as well as its structure and purpose. Furthermore, it analyses the user-statistics of the answered questionnaires, generated by the online-tool, for all three Hungarian elections and for the two questionnaires “Equality of men and women in Hungary” and “Roma in Hungary” which were developed 2015 to keep the civic education aspect of Vokskabin alive and addressing politically and socially relevant issues like gender equality and minority situation, also outside the election period.
The paper raises two main questions: 1. Are there any regional differences of Vokskabin users’ behavior? 2. How does Vokskabin influence the voting behavior (with focus on the electoral participation) and the political knowledge? This part of the study is based on survey questionnaires addressed to the users of Vokskabin.
In addition to the analysis of the statistics the paper aims to highlight the role of voting advice applications in general and the role of Vokskabin in particular, as means of civic education in the 21st century Hungarian society.
Digital divide in the EU countries from the Danube Region
Authors: Şandor Sorin Dan
Published: July 2020

The paper analyzes digital divide in the EU Countries belonging to the Danube Region. Based on data from Eurobarometer 84.2 October 2015, digital divide (both in terms of access and usage) is assessed and then discussed in the light of the evolutions of digital divide in the last ten years for the countries from the region as reflected by Eurostat data. The influence of the most important factors mentioned in the literature (age, education, gender, rural-urban split, socio-economic status) is analyzed for each country.
The results show us that digital divide, while declining, is still of concern in the area. We found that age is a common factor for digital divide in all the cases and education is not influencing the digital divide in any of the countries in discussion. For the other factors their influence varies from country to country.
The difference of the impact between face to face communication compared to political debates in cyber space
Authors: Szarvas Hajnalka , Mező Tamás
Published: July 2020

Singularity or …?
The study will reveal one of the most burning questions of the field of e-governance and edemocracy, the question of the Center for Collective Intelligence of MTI, namely How can people and computers be connected so that—collectively—they act more intelligently than any person, group, or computer has ever done before? Is this possible at all? In the study it will be highlighted which are the neuropsychological effects of human to human communication compared to people and computers. Whether this latter is ever able to substitute personal face to face interactions. Are people more satisfied with electronic services where there is an artificial system in front of them? Which kind of psychological impact does it have on political behaviour and especially participation? Does it really encourage to be more active citizens? Or on the contrary it even deters? Which are the criterias of that? And finally in order to be able to answer these questions we should trace this back to the very original question of what is the real function of communication in human society?
The role of Internet of Things in developing smart cities
Authors: Tirziu Andreea-Maria , Vrabie Catalin
Published: July 2020

A main characteristic of smart cities is the use of information and communications technology in all aspects of city life. In this regard, Internet of Things (IoT) is a core element in the process of developing communities “ruled” by an improved communication, better understanding and wait times decrease. This paper aims to present the ways in which IoT networks and services can contribute to develop smart cities, giving as example various cities that have implemented this concept. The methodology used to carry out this research is both bibliographic – opting here to study the work of specialists in the field, authors from Romania and abroad, and empirical – formed by a case study on various smart cities around the world that use IoT. This type of smart cities is starting to transform all public institutions, changing their culture, from one control-based to one performance-centered. IoT is starting to play an important role in smart cities’ evolution and it brings an improvement in the government-citizens relationship. We have identified that although technology is a central element, there should also be considered the capability and willingness of citizens and public institutions to collaborate in order to implement the best solutions for the communities.
On e-Governance development opportunities in the Republic of Moldova
Authors: Grecu Mihai , Cojocaru Igor , Coşuleanu Ion
Published: July 2020

The process of e-Governance building in the Republic of Moldova, amplified with the adoption of the e-Transformation governmental program, highlighted the issues that require a proper approach to local conditions and specificities.
A specific feature of Moldovan society is that the country's population is mostly rural. In rural areas, the sensitivity to new services and the affordability of ICT tools are lower. Another feature is that the administrative structure at the local level is very fragmented; the administrations manage small budgets that cannot cover the needs of implementing e-Governance solutions.
In general, the capacity to finance ICT projects in the public sector is below the need. At the same time, some trends and indicators regarding the level of e-Governance development in the Republic of Moldova: literacy level, ICT skills, access to the Internet, use of mobile telephony, use of electronic services, etc. shows that there is significant potential to explore new opportunities, in particular, based on innovation and involvement of different social partners to support efforts to build e-Governance.
The article addresses the issue of identifying new opportunities for e-Governance solutions in the context of economic and social disparities present in the Republic of Moldova. The opportunities are based on more active involvement of social stakeholders, the use of more affordable new technologies, and the adoption of policies aimed at optimizing the use of available resources.
Open Government Data in Hungary
Authors: Orbán Anna
Published: July 2020

Today it is increasingly evident that data is the new determining element in the economy and society. Digital data is essential resources for economic growth, competitiveness, innovation, job creation and social development.
For well-founded decisions, real data containing all the necessary information are required. Public organizations are obliged to collect and store vast amounts of data. However, the question arises: who has access to them and for what purposes are they used for?
Open Data has become increasingly prevalent both on organizational and national levels. By making the datasets available to the public, institutions have become more transparent, efficient and more economical. There are EU and national strategies and programs to support open public administration by providing an appropriate legal environment and recommending practical measures.
Freedom of information guarantees the accessibility of public data. However, accessibility is blocked by several challenges and obstacles, such as traditional approaches, legal constraints, practical and technical problems.
The aim of this paper is to interpret the basic concepts of open government data, and present some of the problems of Hungarian data policy, legal regulations and practical implementations.

Authors: Domalewska Dorota
Published: July 2020

New media technologies provide new venues for political communication enabling politicians to wage a permanent campaign. Participatory platforms have paved the way for new forms of political communication during non-election period when those seeking or holding office can increase media coverage, create their public image and foster deeper relationships with the public. The purpose of the paper is to contribute to the discussion on permanent campaign; specifically, the study focuses on presenting the method of embracing new media technologies (in particular Twitter) by politicians’ during a non-election period in Poland. The analysis aims to investigate online activity, the design of Twitter profiles and the implementation of campaign-like techniques by the politicians. The findings shed light on the Polish MPs’ application of participatory platforms as a tool of strategic communication used to increase media visibility, and share messages across in a one-way communication.

Usability of digitized citizens' services
Authors: Stasch Laura , Steidle Anna
Published: July 2020

Germany's public administrations must go digital by law till 2022. The German Online Access Act (our translation for “Onlinezugangsgesetz”, OZG) forces most services offered by public administration on federal, federal state and municipal level to become digitized. For most of these services still being paper-based and Germany not being one of the leaders in e- government according to many sources, the question of user acceptance arises. For answering the question whether the approach used in the digitalization labs leads to the development of digital public services that are accepted by future users, we conducted a heuristic evaluation of a prototype that was developed within the implementation of the OZG. The paper describes the setting, the test undertaken and the outcome and concludes with an estimate, whether the huge paradigm change towards the development of digital public services that are accepted by future users will be successful or not.

The content of soil C-organic is strongly influenced by land management. Plants tend to increase soil organic C-stock, however an increase in soil temperature can increase the rate of decomposition of soil organic matter which will reduce soil organic C-stock. The aim of the study is to look at the relationship of soil organic carbon stock (SOCS) with changes in soil surface temperature. The study was conducted using a survey method consisting of 5 stages, namely preparation, pre-survey, main survey, soil analysis in the laboratory and data processing. Soil sampling is done by purposive random sampling under several land units (LU). LU is limited by the order of the soil, slope, and land use. Based on the land unit map, we found 14 land units in the study area. Soil samples were taken at a depth of 0-20 cm. Surface temperature measurements are carried out directly in the field using a room temperature thermometer. The parameters analyzed are organic-C, organic particulate-C, and bulk density (BD). The research data were processed statistically using simple linear regression equations. The results showed that the measurement of rice field surface temperature had the highest temperature of 34 0C, and rubber plantations had the lowest temperature of 28 0C. Organic-C affects soil BD, the higher the value of organic-C, the lower the BD value. The highest carbon stock was found in soil unit 10 with rubber plantations with a slope of 8-15%, 41 kg m-2 and decreased with increasing slope. The difference in the value of SOCS in rice fields is influenced by land management, because there is no return of crops residue in the form of straw to the ground. The results of the regression analysis showed that surface temperature did not have a significant effect on the SOCS value.Keywords : carbon stock, land use, Padang Laweh
Enigmatic provenance signature of sandstone from the Okwa Group, Botswana
Authors: Andersen T. , Elburg M.A. , Lehmann J.
Published: July 2020

Detrital zircon grains from three samples of sandstone from the Tswaane Formation of the Okwa Group of Botswana have been dated by U-Pb and analysed for Hf isotopes by multicollector LA-ICPMS. The detrital zircon age distribution pattern of the detrital zircons is dominated by a mid-Palaeoproterozoic age fraction (2 000 to 2 150 Ma) with minor late Archaean – early Palaeoproterozoic fractions. The 2 000 to 2 150 Ma zircon grains show a range of epsilon Hf from -12 to 0. The observed age and Hf isotope distributions overlap closely with those of sandstones of the Palaeoproterozoic Waterberg Group and Keis Supergroup of South Africa, but are very different from Neoproterozoic deposits in the region, and from the Takatswaane siltstone of the Okwa Group, all of which are dominated by detrital zircon grains younger than 1 950 Ma. The detrital zircon data indicate that the sources of Tswaane Formation sandstones were either Palaeoproterozoic rocks in the basement of the Kaapvaal Craton, or recycled Palaeoproterozoic sedimentary rocks similar to the Waterberg, Elim or Olifantshoek groups of South Africa. This implies a significant shift in provenance regime between the deposition of the Takatswaane and Tswaane formations. However, the detrital zircon data are also compatible with a completely different scenario in which the Tswaane Formation consists of Palaeoproterozoic sedimentary rock in tectonic rather than depositional contact with the other units of the Okwa Group.
A late Mesozoic – early Cenozoic sedimentary recycling system on the Gondwana rifted margin of southeast Africa
Authors: Andersen T. , Botha G.A. , Elburg M.A.
Published: July 2020

Detrital zircons in late Cretaceous – Palaeogene, calcareous sandstone and conglomerate deposited in continental basins on the southeastern African margin after the breakup of Gondwana have characteristic combinations of age and epsilon-Hf that indicate an origin by recycling of Palaeoproterozoic (Waterberg, Soutpansberg and Pretoria groups) and Phanerozoic (Karoo Supergroup) cover successions. The latter is dominant in the south and east (Boane, Mahosi, Chilojo Cliffs), and the Palaeoproterozoic sources in the northwest (Pafuri, Wright’s Tower, Masisi). This recycling and mixing regime was restricted to late Mesozoic and Palaeogene time in northeastern South Africa and adjoining parts of Mozambique and Zimbabwe. Detrital zircon distribution patterns in these deposits reflect the denudation history of the southern African continental surface after breakup of the Gondwana supercontinent.

Published: July 2020

Актуальність теми дослідження. Технологія високошвидкісного фрезерування є однією з найбільш сучасних і ефективних альтернатив класичним методам обробки, що значно відрізняється якістю і швидкістю обробки, а також можливістю виготовлення виробів із важкооброблюваних матеріалів.
Постановка проблеми. Швидкісне фрезерування переважно реалізується за допомогою багатокоординатних верстатів із числовим програмним керуванням (ЧПК), проте стійкий процес різання неможливо забезпечити на наявному обладнанні без модернізації системи ЧПК, приводу головного руху, який би забезпечував необхідну швидкість різання та використання спеціального інструменту. Аналіз останніх досліджень і публікацій. Основними вимогами до системи ЧПК при високошвидкісній обробці є її швидкодія, можливість забезпечення гладких траєкторій руху інструменту для рівномірного навантаження на нього без численних врізань і виходів. Використання ефективного змащувально-охолоджувального середовища (ЗОТС) зменшує пружні віджимання в технологічній системі при її фіксованій жорсткості. Виділення недосліджених частин загальної проблеми. Впровадження високошвидкісного фрезерування на верстатах із ЧПК стримується відсутністю практичних рекомендацій і потребує додаткових досліджень, зокрема жорсткості верстата.
Постановка завдання. Дослідити можливість модернізації універсально-заточувального верстата з ЧПК моделі ВЗ208Ф3 з метою розширення його технологічних можливостей для високошвидкісного фрезерування поверхонь обертання дисковою фрезою, оснащеною різальними елементами з кубічного нітриду бору. Виклад основного матеріалу. Високошвидкісне фрезерування – сучасний високотехнологічний метод обробки, що дозволяє отримувати найменші перетини зрізу металу при використанні високих швидкостей знімання. Сутність цієї технології полягає у використанні певного діапазону швидкостей різального інструменту, що веде до істотного зниження опору матеріалу при його обробці, чим забезпечується обробка важкооброблюваних матеріалів. Особливістю такої технології є те, що тепло, яке виділяється при обробці, практично повністю зосереджено в
стружці і не перебуває тривалий час у зоні обробки, через що фреза й деталь мало схильні до термічного впливу. Висновки відповідно до статті. У роботі досліджено технологічні можливості універсально-заточувального верстата з ЧПК моделі ВЗ208Ф3 з метою його використання для високошвидкісного фрезерування поверхонь обертання дисковою фрезою, оснащеною різальними елементами із кубічного нітриду бору та обґрунтовано модернізацію його системи ЧПК та вузлів.

MANAGING INFORMATION FOR WORK-INTEGRATED LEARNING AT HIGHER EDUCATION INSTITUTIONS
Authors: Brink Roelien , Mearns Martie , Du Plessis Tanya
Published: July 2020

Higher education institutions (HEIs) in South Africa require teaching and learning to include work-integrated learning (WIL) within specific learning offerings. The different learning options provided by various faculties have unique and diverse procedures which justify different WIL approaches at HEIs. A lack of structure regarding the information management (IM) for WIL across departments results in different processes being followed, which can impact negatively on the optimal utilisation of WIL. Frameworks for IM for WIL, however, have been developed at international HEIs. Using a qualitative approach and phenomenological research design and working with these frameworks as well as the Theory of Motivated Information Management, the researchers collected data using semi-structured individual interviews and group discussions from the University of Cincinnati (UC) and the Northwestern University (NWU) in Illinois, United States (US). This article presents the findings of an IM framework from these two US universities. After research was conducted at a South African university, a conceptual framework was developed for the IM for WIL based on the framework from the international universities that may be implemented at HEIs in South Africa. With time this framework could betested in a number of settings that could lead to the development of a model for IM for WIL in the South African context. The article, however, reports on the findings of the two international universities only and the conceptual framework requires further testing and validation before it can be published.

Published: July 2020

Due to technological developments, innovation and globalisation, research is becoming more complex, requiring wide-ranging skills. A lack of resources and publishing platforms has led to low research output in archives and records management (ARM) in most developing countries in Africa. However, experienced researchers from different countries can collaborate by sharing and transferring knowledge and making optimal use of resources that will lead to the sustainability of research output. Utilising informetrics analysis, as well as co-authorship as the measure for collaboration, this article examines the nature, trend and type of ARM research collaboration in Africa by identifying individuals, institutions and countries that collaborate in order to recommend ways of improving such activities. Quantitative data was extracted from the database of African Journals Online (AJOL) and analysed. The key finding suggested a low level of collaboration among ARM researchers, with the work produced emanating mostly from one institution. The study argues that social and physical proximity contribute to research collaboration in ARM in Africa. The scarcity of literature on ARM in Africa led the article to recommend more collaborative projects whereby established researchers nurture and mentor novice researchers to become self-sustainable in producing scholarly literature. Hopefully, this would help to formulate research agendas to address grand societal challenges, such as a lack of accountability, poor audit results and poor service delivery, which all stem from a breakdown in the records system and a non-sustainable ARM profession in Africa, in order to become on par with the rest of the world.
â€˜NAKED IN THE OPEN AIR â€¦ THE WAVES â€¦ INVITED HERâ€™: ECOCRITICISM AND THE PICTURE BOOK
Authors: Mckenzie John
Published: July 2020

It is an inconvenient truth that the state of the planet is likely to figure powerfully in both the real and the imagined lives of children, in whatever nation state children and young people are situated. Physical space as a literary trope, representing both outer and inner landscapes, has a long tradition in the telling of stories where the child listener/ reader/viewer is often positioned to see nature in terms of binary oppositions. From the survival story â€“ where the island is represented as personally malevolent â€“ to the country garden â€“ where nature is represented as a benign healer; from the wild forest of the folktale â€“ where the wolf-man/rapist roams â€“ to the benevolent beach where children play innocently, children â€˜readâ€™ contradictory ideas about the natural world in the word. This article unlocks some of these binary oppositions in childrenâ€™s literature through an examination of a range of South African and New Zealand picture books, seeking to reveal how various ideologies are inscribed in the visual and verbal space of the picture book. The article asserts that, in the context of globalisation, teachers must be awakened to the opportunity of including eco-criticism in a critical literacy curriculum, developing thus an emancipatory politic.
THE STATUS OF SCHOOL LIBRARIES IN KENYA: THE CASE OF PUBLIC SECONDARY SCHOOLS IN NAIROBI COUNTY

In order for school libraries to contribute sufficiently to better information skills development and the creation of a culture of lifelong learning among students, they require backing through well-articulated policies both at national and individual school level. This article reports on a study that investigated the prevailing status of school libraries in public secondary schools in Nairobi County, Kenya. Using a survey research design, with a response rate of 68 per cent for school principals and 66 per cent for school librarians, the study established that the majority of the schools had school libraries but these were as a result of individual schoolsâ€™ efforts and not a nationwide government policy. Moreover, the school libraries lacked policies; had not embraced contemporary trends in technology; and lacked financial support. The study concluded that school libraries in Nairobi County were inadequately resourced and supported and recommended that the government of Kenya should develop national policies to entrench and support school libraries in the education system.
INFORMATION SEEKING BEHAVIOUR OF BLIND AND VISUALLY IMPAIRED STUDENTS: A CASE STUDY OF THE UNIVERSITY OF KWAZULU-NATAL, PIETERMARITZBURG CAMPUS
Authors: Seyama Lungile , Morris Craig D. , Stilwell Christine
Published: July 2020

Based on a study for a masterâ€™s dissertation, this article reports on an investigation of the information seeking behaviour of blind and visually impaired students. It investigated whether the services provided by the University of KwaZulu-Natal on its Pietermaritzburg campus (hereafter UKZN-PMB) accommodated the information seeking behaviour of blind students and those with visual impairments. The theoretical framework for the study was Wilsonâ€™s (1996) Model of Information Behaviour, Belkinâ€™s (1982) Anomalous Stat of Knowledge approach and Oliverâ€™s (1996) Social Model of Disability. Blind students and those with visual impairments, the subject librarians from the Main Library and the Disability Unit (DU) Co-ordinator were surveyed. The study revealed that the students exhibited information seeking behaviour that included the DU staff as an indispensable part of information access. Recommendations include developing a strategy to implement the UKZN disability policy and allocating a sufficient budget for the purchase of assistive devices or, preferably, incorporating principles of universal design in the information system.

Objectives:

To evaluate anti-psoriatic activity of Phytochemicals on UV-Induced psoriasis in mouse tail model.

Materials and Methods:

Anti-psoriatic activity of selected phytochemicals on UV-Induced psoriasis in mouse tail model. The animals were dividing into 05 groups and each group contain 5 animals. Disease control group did not receive any treatment only exposure to UV-light, vehicle control treated with simple ointment, standard group treated with salicylic acid (1%w/w) ointment, remaining group are treated 1% and 2% selective phytochemical at two concentrations of ointment to topically on the tail skin. And the data were analysed using one way ANOVA followed by two-way ANOVA (Dunnett’s multiple comparisons test).

Results:

There was significant decrease in epidermal thickness (P < 0.05) as compared with control group. In 2% phytoconstituents has shown a significant reduction in the total epidermal thickness 8.4****±0.748, 7.6**±0.6781 and 8*±0.8366 in geraniol, glycyrrhizic acid and ellagic acid treated group, when compare to the disease induced animal, there was no lesion of Munro’s microabscess, capillary loop dilation along with elongation of rete ridges in the section of skin of rats. Psoriasis Severity Index was reduced in test treated groups as compared with that of disease control group. It was slowly reduced to 2nd week, totally (55-70%) reduction in PSI is observed at the time of third week of treatment period.

Conclusion:

The result of the study showed that the 2% of geraniol, ellagic acid, glycyrrhizicacid and hesperidin, exhibited significant activity on UV-induced psoriasis in rodents. The study implies that selected phytoconstituents are a promising research for further investigations to prove its anti-psoriatic activity.
Association of skipping breakfast and different domains of cognitive function among undergraduate medical students: A cross-sectional study
Authors: Kerwani Twinkle , Gupta Sandhya , Epari Venkatarao , Sahoo Jyotiranjan
Published: July 2020

Objectives:

To find out the prevalence of skipping breakfast and its association with different domains of cognitive function.

Materials and Methods:

Using inclusion and exclusion criteria, a representative sample of 184 under graduate students were included. Cognitive function was assessed using previously validated scales of measurement like FDS (Forward Digit Span) and BDS (Backward Digit Span) for assessing short-term and working memory respectively and MMSE (Mini Mental Scale Examination) for assessing global cognitive function. Categorical variables were expressed as a percentage and continuous variables were expressed in terms of mean and median. Mann Whitney U test was used to compare the medians. A P-value of <0.05 was considered statistically significant.

Results:

Almost three-quarter of the study participants were found to have skipped breakfast either once or more than once in a week. All the three scores (FDS, BDS and MMSE) were higher among those who took breakfast. However; only the differences in BDS and MMSE scores were statistically significant.

Conclusion:

It was observed that those who took breakfast had higher BDS and MMSE scores indicating positive association between having breakfast and certain domains of cognitive function. Further, studies with robust study designs are needed to elicit the association of skipping breakfast and cognitive function, which would contribute further to our existing knowledge.
