Freshwater: Towards a Better Understanding of a Wicked Problem
Authors: Sanya Tom 
Published: December 2020

Water begets intricate and profound linkages between multiple systems. Quantitative limits to freshwater availability for human needs, variabilities in the water cycle and environmental water requirements interact with water source pollution. The arising tensions are a great challenge of immense contemporary significance that can best be described as a wicked problem – a problem with multiple dimensions that presents unexpected consequences when engaged. Water challenges make vivid the compromises that must be made between the environment and development. These compromises surface in the conflict between ecocentric and technocentric discourse. Globally, there is evidence of numerous disciplinary and interdisciplinary water-related studies both in the past and ongoing. But there is no meta-mapping of various dimensions of such research to give a clear overview of what has been and what needs to be done. Consequences of this oversight may include unnecessary duplication of research, difficulty in articulating knowledge gaps, and inability to see beyond disciplinary boundaries. The author suggests an outline of how these difficulties can be engaged. This is done through a wide-ranging literature review to identify a range of issues of focus, which issues are then themed into imperatives for water research. These imperatives are subsequently systematised using four normative descriptors: problem, drivers, and mitigation measures. In combination, these descriptors articulate a spectrum of the key issues around water research. The key issues are mapped onto various academic disciplines and societal partners to outline a schema for the positioning of water research. The proposed mapping can facilitate interdisciplinary and transdisciplinary (IDTD) research by allowing researchers to benefit from relevant existing bodies of knowledge while also making explicit knowledge gaps and opportunities for collaboration. By locating academic fields within different worldviews, the outlined schema reveals common ground beyond disciplinary confines around which IDTD research can be instigated.

Published: December 2020

Abstract
Recently, the utilization of wastes, recovery of high value-added products from waste, and their use as raw materials in other industries with the logic of industrial symbiosis has become an important issue. In this study, removal efficiency of Reactive Orange 16 (RO16) dye from aqueous solution was studied using TiO2 catalyst recycled from an industrial waste effluent. The recycling of TiO2 waste from a paints manufacturing industry was carried out by sintering the TiO2-containing waste. The catalyst usability of TiO2-containing powder was then investigated in the removal of RO16 dye by photocatalytic oxidation process. In photocatalytic oxidation studies, TiO2/UV and TiO2/UV/H2O2 processes were investigated, where the effect of annealing temperature, the effect of H2O2 concentration, and the adsorption and photocatalytic effects on RO16 dye removal were studied. The results showed that 100% RO16 removal was obtained for the 10 mg/L initial RO16 concentration using the TiO2 (1 g/L)/UV process. At high initial RO16 concentration (50 mg/L), 100% RO16 removal was achieved by adding 10 mM H2O2.
The Quality of Instructional YouTube Videos for the Administration of Intranasal Spray: Observational Study
Authors: Peters-Geven Marije M , Rollema Corine , Metting Esther I , van Roon Eric N , de Vries Tjalling W 
Published: December 2020

Background
Allergic rhinitis is a common disorder affecting both children and adults. Recommended treatment consists of intranasal corticosteroid spray administration, but only few patients administer the nasal spray in the correct technical manner. A wrong administration technique may result in side effects and affect the efficacy and adherence, thus making accurate administration instructions indispensable. Unfortunately, information about intranasal drug administration is generally not explained accurately, thereby leading to confusion among patients and inaccuracy in the self-administration of drugs.

Objective
In this study, we analyzed instructional videos available on YouTube for the administration of nasal sprays for allergic rhinitis. Our aim was to determine if the videos provided instructions in accordance with the standardized nationwide patient protocol in the Netherlands for intranasal spray administration.

Methods
Instructional videos for the administration of aqueous formulations of nasal spray for allergic rhinitis were found on YouTube. All videos were reviewed by 2 researchers and scored using the instructions from the Dutch standardized protocol. Correct instructions were given a score of 1, while incorrect or missing instructions were given a score of 0. The interrater reliability using Cohen ĸ was used to determine the differences in the scores between the researchers.

Results
We identified 33 YouTube videos made by different health care professionals and pharmaceutical companies around the world. None of the videos displayed all the steps correctly, while 5 of the 33 (15%) videos displayed over 75% of the steps correctly. The median score of the correctly displayed steps was 11 out of 19 (range 2-17, IQR 6). The interrater reliability using Cohen ĸ was statistically significant (range 0.872-1.00, P<.001). The steps “neutral position of the head,” “breathing out through the mouth,” and “periodically cleaning with water” scored the lowest and were incorrectly displayed in 28 (85%), 28 (85%), and 30 (91%) of the 33 videos, respectively.

Conclusions
The findings of our study revealed that only few instructional videos on YouTube provided correct instructions for the administration of nasal sprays to patients. The inaccuracy of the instructions for nasal spray administration in the majority of the videos may lead to confusion in patients and incorrect use of nasal sprays. In the future, it is important to make evidence-based instructional videos that show patients the correct technique of nasal spray administration.

The Effects of Workplace-Based HIV Self-testing on Uptake of Testing and Linkage to HIV Care or Prevention by Men in Uganda (WISe-Men): Protocol for a Cluster Randomized Trial
Authors: Muwanguzi Patience A , Ngabirano Tom Denis , Kiwanuka Noah , Nelson LaRon E , Nasuuna Esther M , Osingada Charles Peter , Nabunya Racheal , Nakanjako Damalie , Sewankambo Nelson K 
Published: December 2020

Background
HIV testing uptake remains low among men in sub-Saharan Africa. HIV self-testing (HIVST) at the workplace is a novel approach to increase the availability of, and access to, testing among men. However, both access and linkage to posttest services remain a challenge.

Objective
The aim of this protocol is to describe a cluster randomized trial (CRT)—Workplace-Based HIV Self-testing Among Men (WISe-Men)—to evaluate the effect of HIVST in workplace settings on the uptake of HIV testing services (HTS) and linkage to treatment and prevention services among men employed in private security services in Uganda.

Methods
This is a two-arm CRT involving men employed in private security services in two Ugandan districts. The participants in the intervention clusters will undergo workplace-based HIVST using OraQuick test kits. Those in the control clusters will receive routine HTS at their work premises. In addition to HTS, participants in both the intervention and control arms will undergo other tests and assessments, which include blood pressure assessment, blood glucose and BMI measurement, and rapid diagnostic testing for syphilis. The primary outcome is the uptake of HIV testing. The secondary outcomes include HIV status reporting, linkage into HIV care and confirmatory testing following HIVST, initiation of antiretroviral therapy following a confirmatory HIV test, the uptake of voluntary medical male circumcision, consistent condom use, and the uptake of pre-exposure prophylaxis by the most at-risk populations.

Results
Participant enrollment commenced in February 2020, and the trial is still recruiting study participants. Follow-up for currently enrolled participants is ongoing. Data collection and analysis is expected to be completed in December 2021.

Conclusions
The WISe-Men trial will provide information regarding whether self-testing at worksites increases the uptake of HIV testing as well as the linkage to care and prevention services at male-dominated workplaces in Uganda. Additionally, the findings will help us propose strategies for improving men’s engagement in HTS and ways to improve linkage to further care following a reactive or nonreactive HIVST result.

Effect of Phosphate-Specific Diet Therapy on Phosphate Levels in Adults Undergoing Maintenance Hemodialysis
Authors: St-Jules David E. , Rozga Mary R. , Handu Deepa , Carrero Juan Jesus 
Published: December 2020

Background and objectives
Hyperphosphatemia is a persistent problem in individuals undergoing maintenance hemodialysis, which may contribute to vascular and bone complications. In some dialysis centers, dietitians work with patients to help them manage serum phosphate. Given the regularity of hyperphosphatemia in this population and constraints on kidney dietitian time, the authors aimed to evaluate the evidence for this practice.

Design, setting, participants, & measurements
There was a systematic review and meta-analysis of clinical trials. MEDLINE, Embase, CINAHL, Web of Science, Cochrane Central Register of Controlled Trials, and other databases were searched for controlled trials published from January 2000 until November 2019 in the English language. Included studies were required to examine the effect of phosphate-specific diet therapy provided by a dietitian on serum phosphate in individuals on hemodialysis. Risk of bias and certainty of evidence were assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) method.

Results
Of the 8054 titles/abstracts identified, 168 articles were reviewed, and 12 clinical trials (11 randomized, one nonrandomized) were included. Diet therapy reduced serum phosphate compared with controls in all studies, reaching statistical significance in eight studies, although overall certainty of evidence was low, primarily due to randomization issues and deviations from protocol. Monthly diet therapy (20–30 minutes) significantly lowered serum phosphate in patients with persistent hyperphosphatemia for 4–6 months, without compromising nutrition status (mean difference, −0.87 mg/dl; 95% confidence interval, −1.40 to −0.33 mg/dl), but appeared unlikely to maintain these effects if discontinued. Unfortunately, trials were too varied in design, setting, and approach to appropriately pool in meta-analysis, and were too limited in number to evaluate the timing, dose, and strategy of phosphate-specific diet therapy.

Conclusions
There is low-quality evidence that monthly diet therapy by a dietitian appears to be a safe and efficacious treatment for persistent hyperphosphatemia in patients on HD.
The analysis of a free two-layer composite beamon the elastic foundation
Authors: Filatov Vladimir V. , Kuzhin Bulat F. , Thi Linh Quyen Hoang  
Published: December 2020

Abstract
Introduction. This article offers a methodology for the analysis of a two-layer composite beam on an elastic foundation that represents a one-parameter Winkler model. The behaviour of two-layer beams is described by A.R. Rzhanitsyn in his theory of composite rods that have rigid transverse and elastic-yielding longitudinal connections between layers. The theory of composite rods allows to study the stress-strain state (SSS) of multilayer foundation beams, having a layer featuring low thermal conductivity, and perforated beams.
Materials and methods. However, analytical solutions to these problems involve certain difficulties; therefore, they are often inapplicable. We propose to apply a numerical method, a method of successive approximations (MSA), developed by professor R.F. Gabbasov at the Department of structural and theoretical mechanics of the Moscow State University of Civil Engineering. MSA has proven to be an effective and highly accurate method designated for analyzing static/dynamic loads, applied to beams, slabs and shells, and for making stability calculations. The difference-based variation of the MSA method has a number of advantages over difference equations of the “classical” finite difference method (FDM). The proposed methodology allows to take into account various types of boundary conditions without involving contour points. Сoncentrated forces, concentrated moments, and piecewise distributed loads can be taken into account as loading types.
The article describes a problem solving algorithm. The system of initial differential equations is solved using difference analogs. Typical difference equations for regular and boundary points are provided.
Results. The analysis of a composite free-lying beam on an elastic foundation illustrates the proposed approach. The qua-lity of the analysis results is controlled by performing a numerical study of the solution convergence using several nested meshes.
Conclusions. The proposed method can be used in the engineering practice of design organizations and the educational process of higher educational institutions training civil engineering specialists.
Knowledge Transfer About Earthquake Disaster Mitigation To Children Through TF-IDF
Authors: Umran Maria , Sarim Hafiz Mohd. 
Published: December 2020

Abstract: Past observations during a disaster identify that when children are separated from parents, they suffer due to the inability to comprehend disaster mitigation concepts. This study proposes a process from the existing framework K-Nearest Neighbor (KNN) and Term Frequency - Inverse Document Frequency (TF-IDF) for extracting a large body of knowledge in the form of documents into simple words. Those simple words can be arranged into contextual lyrics utilizing an Artificial Intelligence lyrics generator and then orchestrated into a song using a music generator. The piece, which is the output of the proposed process, is utilized to transfer the knowledge about earthquake disaster mitigation to children. A quantitative analysis of questionnaires on students aged 9-10 in Banda Aceh shows the song's highly significant effect in transferring the knowledge about earthquake disaster mitigation to children.

Praca to jeden z najważniejszych czynników resocjalizacji. Rozwija i kształtuje właściwe prospołeczne postawy więźniów. Stanowi narzędzie reedukacji i działań na rzecz zapobiegania powrotności do przestępstwa. Wysoki poziom poczucia sensu pracy prowadzi do zwiększenia satysfakcji i zaangażowania więźniów. Pomaga również w odnalezieniu się na rynku pracy po zakończeniu odbywania kary pozbawienia wolności. W badaniach uczestniczyło 198 pracujących osadzonych przebywających w Areszcie Śledczym w Lublinie. zastosowano kwestionariusz WAMI M. Steger’a, Skalę Satysfakcji z Pracy A. Zalewskiej oraz kwestionariusz autorski. Zbadano, czy istnieje związek między satysfakcją z pracy a poczuciem sensu pracy, a także jakie są deklaracje dotyczące zamiaru podjęcia pracy po odbyciu kary pozbawienia wolności. Więźniowie z wyższym osobistym poczuciem sensu pracy odczuwają większą satysfakcję z pracy, a także częściej chcą działać dla dobra społecznego, budują bardziej realistyczne plany wolnościowe, odczuwają mniejsze obawy przed odnalezieniem się na rynku pracy po zakończeniu odbywania kary. Odpłatność za pracę więźniów wpływa na poziom odczuwanej z niej satysfakcji. Wysokie poczucie sensu pracy i zadowolenia z możliwości jej wykonywania wśród pracujących więźniów są istotnym elementem warunkującym zaangażowanie osadzonych w proces resocjalizacji.
Znaczenie zasobów w przystosowaniu osobistym osób przyjmujących leki bez recepty
Authors: Modrzyński Robert , Radoń Aleksandra 
Published: December 2020

Przyjmowanie leków bez recepty stało się w Polsce powszechnym zjawiskiem. Co piąta osoba używa ich niezgodnie z zaleceniami, niejednokrotnie przekraczając dopuszczalnedawki. Problem ten dotyczy różnych grup społecznych i zawodowych. Nie zawsze wiąże się to jednak z uzależnieniem i może doprowadzić do strat na wielu różnych obszarach. Bezwątpienia poszukiwanie psychologicznych powiązań, stanowiących o potrzebie sięgania po lekarstwa bez zalecenia lekarskiego staje się pierwszoplanowe. Teoria Zachowania Zasobów Stevana E. Hobfolla (COR) może stanowić alternatywną koncepcję rozumienia zjawiska używania leków bez recepty. Teoria ta opiera się na założeniu, że aktywność człowieka jest skoncentrowana na zdobywaniu, utrzymywaniu i ochronie zasobów. Ich zdobywanie lub utrata ma fundamentalne znaczenie dla jakości życia i stanowi źródło motywacji do określonego zachowania. Z perspektywy COR utrata zasobów lub brak możliwości ich pozyskania może tłumaczyć wysoki odsetek osób używających leki bez zalecenia lekarskiego. Głównym celem pracy jest uzyskanie odpowiedzi na pytanie, jakie funkcje spełnia dystrybucja zasobów w kształtowaniu przystosowania osobistego. Ponadto równie ważne jest rozstrzygnięcie, jakie istnieją zależności pomiędzy czynnikami psychospołecznymi a przystosowaniem osobistym u osób przyjmujących leki bez recepty.
Materiał i metody: Badania miały charakter poprzeczny. Zastosowano kwestionariuszowe badania 300 osób używających leki bez zalecenia lekarskiego. Wykorzystano do tego Kwestionariusz Oceny Zachowania Zasobów S.E. Hobfolla (COR-E), Test Zdań Niedokończonych (RISB) J. Rottera, Inwentarz Depresji Beck’a (BDI) oraz Wielowymiarową Skalę Spostrzegania Wsparcia Społecznego (MSPSS) G. Zimeta.
Wyniki: Modelowanie równań strukturalnych wskazało na przyczynową relację pomiędzy zyskiem w zasobach a przystosowaniem osobistym (p = 0,001) jak i utraty zasobów i przystosowania osobistego (p = 0,003). Powiększająca się pula posiadanych zasobów oraz mniejsze doświadczanie ich utraty są predyktorami przystosowania. Potwierdzona została hipoteza mówiąca, że proces pozytywnej adaptacji u osób przyjmujących leki bez recepty zależy od dystrybucji zasobów.
Wnioski: Osoby przyjmujące leki bez recepty w sytuacji doświadczania utraty zasobów przejawiają symptomy nieprzystosowania osobistego. Umiejętność właściwego przystosowania siędo zmieniających się warunków życia i radzenia sobie z problemami zależy przede wszystkim od możliwości pozyskiwania zasobów.

Iron rust was an iron oxide compound that was less attractive, dirty, brown in color, and could pollute the environment, causing water to turn brown. To minimize iron contamination, conversion was carried out into iron (III) sulfate which was useful as an adsorbent for textile dyes. The purpose of this study was to determine the effect of sulfuric acid concentration and volume of H2O2 10% used to convert iron rust into optimal iron (III) sulfate compounds. The method used was a laboratory experiment on a batch scale and the hydrate content in iron (III) sulfate was carried out by the gravimetric method and its ability as an adsorbent was carried out based on the adsorption of dyes using the spectrophotometric method. The results showed that a reactor filled with 3 grams of iron rust powder and 100 mL of sulfuric acid was stirred at 425 rpm at 80 0C for 30 minutes, added 15 ml 10% H2O2 followed by stirring and heating until the solution was saturated, cooled to form crystals. The crystalline yield in these conditions was the increase in sulfuric acid concentration which resulted in low process efficiency, namely 30.34% at 50% sulfuric acid concentration and 15 mL 10% H2O2. The addition of 10% H2O2 solution to 50 mL of 20% sulfuric acid solution and 3.0 grams of a carat as much as 5 mL-10 mL 10% H2O2 produced iron (III) sulfate with 26.53% process efficiency. Iron (III) sulfate is a white, light gray crystal with the chemical formula Fe2 (SO4)3.5 H2O which was a rhombic shaped crystal. and able to absorb the dye which showed that 1.0 g of iron (III) sulfate was able to absorb the highest amount of red dye in a volume of 100 mL of textile dye solution.

Soil Quality Assessment in Relation to Food Crop Productivity to Support Agribusiness-Based of Dry Land Management by Scoring of Soil Quality
Authors: M Rachman L 
Published: December 2020

To support Indonesian’s food self-sufficiency program, more quantitative and accurate data are required on the character of soil data needed, which can be more easily understood, practical and suitable for crop selection as well as for the right fertilizer recommendations to support the agribusiness development, implementation and operation. The purpose of this research is to develop and assess soil quality in relation to the productivity of major food crops by using Soil Quality Score Plus (SQS Plus) to support agribusiness-based management of dry lands. The use of SQS for assessing soil quality in principle determines the weighted average score obtained from the score of each selected key parameter multiplied by its weight. The SQS for the 36 locations observed varies from 2.36 (low) to 4.12 (high). SQS Plus adds letter(s) after a score to indicate the limiting factor(s) of soil ecosystem. The most limiting factor is low carbon organic content (72.2 % from the 36 locations observed), followed by low P availability (58.3%), and low total organic N (41.7%). Data of correlation between SQS and crop productivity is not good as expected. Crop growth and crop production are not only determined by soil quality and its limiting factors.
