Abstract
Objective: The main goal of this paper is to visualize and draw the intellectual and cognitive structures of information retrieval (IR) in the medical sciences through the use of Science Mapping. Methods: This Scientometrics research has been undertaking using Mapping Knowledge Domain (MKD) methods and drawing scientific maps to analyze scientific products and show their trends. In this study, we recruited all documents indexed in the Web of Science database (WOS), with the topic of storing and retrieval of information in medical sciences. To analyze the results, 3 software SciMAT-v1.1.04, VOSviewer-v1.6.14, CitNetExplorer_v1.0.0 were used. Results: Our results show that most scientific productions in this field fall into two categories: 1. Effective methods of organizing information and 2. Application and operation of IR system in the process of intelligent questioning and answering, and analyzing information behaviors of physicians and health professionals". The results showed that the similarity index increased over time from 0.43 to 0.71. Analysis of the findings shows that Similarity measures, Expert systems, Concepts, Experience, Answers, and Multi-model IR clusters are considered as mature and completely centralized clusters in the first quarter of the strategic chart. Conclusions: The effectiveness of scientific documents based on answering clinical questions and focusing on health professionals' information behaviors has increased compared to search methods and tools.

Abstract
Improved control of malaria caused by Plasmodium vivax can be achieved with the discovery of new antimalarials with radical cure efficacy, including prevention of relapse caused by hypnozoites residing in the liver of vivax patients. We screened several compound libraries against P. vivax liver stages, including 1566 compounds against mature hypnozoites, resulting in one drug-like and several probe-like hits useful for investigating hypnozoite biology. Primaquine and tafenoquine, administered in combination with chloroquine, are currently the only FDA-approved antimalarials for radical cure, yet their activity against mature P. vivax hypnozoites has not yet been demonstrated in vitro. By developing an extended assay, we show both drugs are individually hypnozonticidal and made more potent when partnered with chloroquine, similar to clinically-relevant combinations. Post-hoc analyses of screening data revealed excellent performance of ionophore controls and the high quality of single point assays, demonstrating a platform able to support the screening of greater compound numbers. A comparison of P. vivax liver stage activity data with that of the P. cynomolgi blood, P. falciparum blood, and P. berghei liver stages reveals little activity overlap, indicating that the delivery of new radical curative agents killing P. vivax hypnozoites requires an independent, focused drug development test cascade.
Hochschullehre im Pandemiebetrieb
Authors: Karapanos Marios , Pelz Robert , Hawlitschek Patrick , Wollersheim Heinz-Werner 
Published: January 2021

Im Sommersemester 2020 beteiligten sich 3469 Studierende sächsischer Hochschulen an einer Onlinebefragung zum Studium während der Coronapandemie. Trotz Campusschliessungen konnten die Befragten ihr Studium weitgehend wie geplant fortführen. Während die technische Ausstattung der Studierenden eine Teilnahme an digitalen Lehrveranstaltungen zuliess, zeigten sich Defizite bei der Qualität der Internetverbindung. Im Vergleich zum Vorsemester wurden die Studienorganisation als moderat (d = -0.48, 95 % CI [-0.52, -0.45]), Lernaktivitäten als deutlich (d = -0.86, 95 % CI [-0.90, -0.82]) schwerer empfunden. Auch die Konzentration auf das Studium fiel den Befragten schwerer als im Semester davor (d = -0.69, 95 % CI [-0.72, -0.65]). Mit den angebotenen Lernmedien zeigten sich die Befragten tendenziell zufrieden. Vor allem Learning-Management-Systeme, digitale Texte und Präsentationen dominierten das Lerngeschehen an den sächsischen Hochschulen. Fehlende soziale Interaktionen mit Peers und fehlende lernbezogene Interaktionen mit Dozentinnen und Dozenten wurden als besonders nachteilig erlebt. Zeit- und Kostenersparnisse sowie mehr Autonomie beim Lernen sind die grössten Vorteile des Studierens von zu Hause. Es zeigen sich keine Hinweise, dass leistungsschwache Studierende von den veränderten Studienbedingungen stärker nachteilig betroffen waren.
Improving the integrated hydrological simulation on a data-scarce catchment with multi-objective calibration
Authors: He Qianwen , Molkenthin Frank 
Published: January 2021

Abstract
The process-based hydrological model Soil and Water Assessment Tool ensures the simulation's reliability by calibration. Compared to the commonly applied single-objective calibration, multi-objective calibration benefits the spatial parameterization and the simulation of specific processes. However, the requirements of additional observations and the practical procedure are among the reasons to prevent the wider application of the multi-objective calibration. This study proposes to consider three groups of objectives for the calibration: multisite, multi-objective function, and multi-metric. For the study catchment with limited observations like the Yuan River Catchment (YRC) in China, the three groups corresponded to discharge from three hydrometric stations, both Nash–Sutcliffe efficiency (NSE) and inversed NSE for discharge evaluation, and MODIS global terrestrial evapotranspiration product and baseflow filtered from discharge as metrics, respectively. The applicability of two multi-objective calibration approaches, the Euclidean distance and nondominated sorting genetic algorithm II, was analyzed to calibrate the above-mentioned objectives for the YRC. Results show that multi-objective calibration has simultaneously ensured the model's better performance in terms of the spatial parameterization, the magnitude of the output time series, and the water balance components, and it also reduces the parameter and prediction uncertainty. The study thus leads to a generalized, recommended procedure for catchments with data scarcity to perform the multi-objective calibration.

Published: January 2021

Abstract
This study compared the effects of four forest canopies on throughfall chemistry in the Qinling Mountains, China. Rainfall and throughfall samples were collected in stands of Quercus aliena (Qa) var. Acuteserrata, Pinus tabulaeformis (Pt), P. armandii (Pa), and mixed broad-leaved (Mb) trees from 2009 to 2011. The results indicated that the pH of the rainfall, which was mildly acidic, increased as it passed through the forest canopy. The pH increased more within the broad-leaved forest canopy than the coniferous forest. Concentrations of decreased as rainfall passed through the Qa canopy but increased after passing through the other species. The concentrations of and Zn, Cd and Pb decreased as rainfall passed through the four canopies. The coniferous forest canopy was more effective than the broad-leaved forest in reducing in rainwater. The decreases in Cd concentrations were similar among the four canopies. The Pb concentration decreased the most among the heavy metals, and the order of the decrease was Qa &gt; Pt &gt; Pa &gt; Mb. The results may provide a basis for the selection of tree species for afforestation in water sources in the Qinling Mountains and similar areas.
Decision support system for selection of appropriate water supply and sanitation technologies in developing countries
Authors: Bouabid Ali , Louis Garrick 
Published: January 2021

Abstract
Access to water supply and sanitation services remains a challenge in many parts of the world. The expected growth of the world's population, from about 7.8 billion people today to 9.8 billion people by 2050, and to around 11 billion people by the end of 2100, will create even higher demand and a greater strain on these basic services. Goal 6 of the United Nations Sustainable Development Goal (SDG) aims to ‘Ensure availability and sustainable management of water and sanitation for all’ by 2030. However, in a recent report, UN-Water warns us that if things continue on the current path, the world will miss the targets of SDG 6. The selection of appropriate water and sanitation technologies is key to meeting SDG 6 targets. This paper presents an original framework of a decision support system (DSS) for the selection of appropriate water supply and sanitation (Watsan) technologies in developing countries. The proposed DSS has three components. The first component is the user interface, where the inputs are the assessment of a community's capacity to manage a given water supply or sanitation system, and its regional specificity. The second component of the DSS is a database of Watsan technologies classified according to the capacity requirement level (CRL) metric, and finally, the third component is a matching algorithm for the selection of appropriate Watsan technology options. Case studies and simulations results are presented for the evaluation of the performance of the decision support system.

Abstract
Identification and quantification of environmental and socio-economic impact risks and effective monitoring of water projects are crucial for sustainable water resource management. Hence, the present study was conducted with the objectives of identifying potential environmental risks of different stages of the development of a new water supply scheme located in the wet zone of Sri Lanka, and categorizing identified impacts based on their significance. A rapid environmental assessment (REA) was followed to identify the upstream point source pollution and downstream water uses in the immediate catchment. Subsequently, a semi quantitative approach was conducted to screen the environmental, social, and economic risks concerning likelihood and sensitivity of the impact. Besides, an analysis of physico-chemical and biological parameters of water quality was conducted in the intake location. The semi quantitative method highlighted that low and medium risk with ecological impacts (50%), low risks towards sustainability of water source (75%), medium level constructional impacts (60%), and very high-level impacts at the operational stage were available (50%). A water quality monitoring program revealed that Escherichia coli count, total coliform bacterial count, and colour of the water were above the standard limits in the nearby freshwater source. In conclusion, a similar approach can be implemented worldwide as a reference to determine the potential socio-environmental consequences in water supply projects to minimize the adverse impacts. Through this study, sustainable mitigation measures were proposed accordingly to prevent the impacts and to strengthen the long-term viability of the new Rural Water Supply Scheme.

Published: January 2021

Background
Smartphones have become an essential part of everyday life and it is undeniable that apps offer enormous opportunities for dealing with future challenges in public health. Nevertheless, the exact patient requirements for medical apps in the field of orthopedic and trauma surgery are currently unknown.

Objective
The aim of this study was to define target groups, evaluate patient requirements, and the potential and pitfalls regarding medical apps specific for patients receiving orthopedic and trauma surgical care.

Methods
A prospective multicenter study was conducted between August 2018 and December 2019 at a German trauma center and 3 trauma surgery/orthopedic practices. A paper-based survey consisting of 15 questions evaluated information regarding smartphone and medical app usage behavior. In addition, suggested app functions were rated using Likert scales. Descriptive statistics and binary log-binomial regression were performed.

Results
A total of 1055 questionnaires were included in our statistical analysis. Approximately 89.57% (945/1055) of the patients in this study owned a smartphone. Smartphone ownership probability decreased with every decade of life and increased with higher levels of education. Medical information was obtained via mobile web access by 62.65% (661/1055) of the patients; this correlated with smartphone ownership in regard to age and educational level. Only 11.18% (118/1055) of the patients reported previous medical app usage, and 3.50% (37/1055) of the patients received an app recommendation from a physician. More than half (594/1055, 56.30%) of the patients were unwilling to pay for a medical app. The highest rated app functions were information about medication, behavioral guidelines, and medical record archival. An improved treatment experience was reported through the suggested app features by 71.18% (751/1055) of the patients.

Conclusions
Mobile devices are a widely used source of information for medical content, but only a minority of the population reported previous medical app usage. The main target group for medical apps among patients receiving orthopedic and trauma surgical care tends to be the younger population, which results in a danger of excluding fringe groups, especially the older adults. Education seems to be one of the most important pull factors to use smartphones or a mobile web connection to obtain health information. Medical apps primarily focusing on an optimized patient education and flow of information seem to have the potential to support patients in health issues, at least in their subjective perception. For future target group–oriented app developments, further evidence on the clinical application, feasibility, and acceptance of app usage are necessary in order to avoid patient endangerment and to limit socioeconomic costs.

Published: January 2021

This study discusses all the potential relationships between monetary, macroeconomic, social and income inequality in an integrated manner by making Indonesia a concrete case study. This empirical study discussed the relationship based on theoretical modelling and carried out through appropriate estimators applied to the data of 33 provinces in Indonesia. To achieve this objective, the simultaneous model of seemingly unrelated regressions (SUR) was used. The results concluded that there are variables that jointly determined the monetary, macroeconomic and social also income inequality. Like, consumption can increase inflation and macroeconomic while at the same time can reduce population growth and human development, and increases income inequality. Savings which determine credit also pushes macroeconomics while simultaneously increasing population growth, and it can reduce income inequality. Minimum wages can reduce inflation and encourage production growth, while increases human development and reduces population growth also can reduce income inequality. Unemployment can also reduce inflation and increase economic growth, at the same time reduces population growth and human development while increases income inequality. Education and health encourages economic growth and the level of human development then can reduce income inequality.

Published: January 2021

Conservation is an effort to return natural resources to their habitat to restore the ecosystem balance, which can be done in-situ and ex-situ. Coelogyne rochussenii orchid conservation efforts are essential to maintain its sustainability. The purpose of this study was to characterize C. rochussenii orchids from Bukit Rimbang and Bukit Baling Wildlife Sanctuary as a source of tissue culture explants to support ex-situ conservation efforts. Orchid plant samples were obtained through exploration in three locations with an altitude of 92 masl, and then the characterization of leaf morphology, pseudobulbs, roots, and fruit were carried out. The characterization results showed that the young pseudobulbs, young leaves, healthy roots, and physiologically ripe fruits of the C. rochussenii orchids obtained could be used as a source of explants to support ex-situ conservation efforts.Keywords: ex-situ conservation, physiologically mature, young pseudobulbs

Authors: Modupe Ogundola Cecilia 
Published: January 2021

This study examined the effects of non-verbal interaction pattern on students’ interest in keyboarding in Colleges of Education in Southwest, Nigeria. It adopted quasi-experimental research design of pre-test, post-test non-equivalent control group design. The population for the study was 109 year one students of Office Technology and Management in state owned Colleges of Education in Southwest, Nigeria. Multistage sampling procedure was used to select 35 NCE I students in two of the Colleges offering OTM in Southwest, Nigeria, this comprised of 26 females and 9 males. One research questions and three null hypotheses tested at 0.05 level of significance guided the study. The instrument used for data collection was the Keyboarding Interest Inventory (KII). The KII was developed by the researcher and was subjected to face and content validity by three OTM experts. Cronbach Alpha was used to determine the internal consistency of the KII items. The reliability coefficient computed for the KII was 0.89. Mean was used to answer the research questions, while t-test was employed to test the hypotheses. It was observed that non-verbal interaction technique was more effective in stimulating students’ interest than the conventional method in keyboarding. There was also no significant difference between the interests of students in the experimental (non-verbal) groups based on gender. It was thereafter recommended that NCCE should incorporate non-verbal interaction pattern into the teaching of keyboarding. Lecturers of keyboarding should prepare their classes in such a way that students are allowed ample opportunity to critically think, interact freely with one another, discourage students’ passiveness and improve performance in pair and group activities among other recommendations.
Herd Immunity in India: A Review
Authors: Khan Sheema Fatima 
Published: January 2021

Herd Immunity is a brilliant solution to tackle and control global pandemics, if taken proper route for immunization such as through vaccination. It is defined as the number of immune individuals against a transmissible virus in a completely susceptible population. The term herd protection or herd effect is the protection to the whole population due to herd immunity. Herd immunity threshold is the minimum proportion of immune population required for herd effect or herd protection. To calculate the threshold, we use basic reproduction number (R0) to measure the rate of transmission of pathogen, in this case SARS-CoV-2. However, a better measure is effective reproduction number (Re). India is major example of herd immunity. Despite strict lockdown and other Covid measure, due to already crowded area the virus could spread fast and to vast majority of people if one of them were to catch it. This explains the steady decline in the number of coronavirus cases in India. At the end, until an approved effective vaccination available, public will still need to follow all the CDC guidelines in order to avoid the large deaths along with natural infection.
