Published: July 2021

Graphical User Interface or better known as the user interface is the liaison of users with electronic devices such as computers. The Graphical User Interface uses icons, menus, and some other visual indicators to represent the information contained in the interface of the application being used. The Graphical User Interface I must pass the Graphical User Interface Testing stage to ensure that every element in the Graphical User Interface is not an error and by the specified one. Also, we know that Graphical User Interface Testing is a set of activities that aim to test the Graphical User Interface I of the test object to ensure that the Graphical User Interface complies with the specifications specified in the software design document. In this research, we try to compare four Graphical User Interface testing tools which ae: Robotium, Espresso, UI Automator, and Pix2Code. By exploring these 4 testing tools we find out that Pix2code can only identify objects, especially label objects. Pix2code can only meet 3 out of 7 predefined criteria. This indicates that there are still many objects of the android application that Pix2code has not been able to identify. In other words in the Graphical User Interface testing section, pix2code can play a role in identifying each object contained in the application and can be done at the design stage. The result that we get from this research is that the GUI testing tools could identify many parts and almost every object in the application except the Pix2code. For future development, Pix2code as a testing tool requires development in the form of a desktop display such as the UI Automatorviewer so that it can display every detail of the object including the attributes of the object.
Security Analysis and Improvement of Lighweight VANET Authentication Protocol (Case Study : Zhao et al. LVAP)
Authors: Siswantyo Sepha
Published: July 2021

VANET is an ad-hoc network implemented on vehicle communication to ensure traffic safety and traffic management efficiency. VANET security is a concern because of various vulnerabilities, especially from authentication criteria that the attacker can exploit. VANET is vulnerable to Sybil attack, entity impersonation, message modification, and identity falsification. Several mechanisms and protocols have been developed to address these vulnerabilities. The design of the VANET authentication protocol also needs to be proven using formal methods to ensure that the protocol meets the required security criteria.  In this research, the security of VANET authentication protocol developed by Zhao et al. was analyzed using the Datta et al. security protocol analysis method. Instead of BAN Logic, the Scyther tool was used to verify security claims and find possible attacks. Our Security analysis results show that Zhao et al.'s protocol does not meet confidentiality and entity authentication criteria. Scyther tool can find attacks on nonce confidentiality and man-in-the-middle attack. Therefore, we modify Zhao et al. protocol by adding signature and session key confirmation to improve its security. Based on analysis results, our modified Zhao et al. authentication protocol met confidentiality and entity authentication criteria. The use of signature and session key confirmation prevents man-in-the-middle attack and protects nonce confidentiality. Therefore, our research concludes that modified Zhao et al. authentication protocol more secure than the original protocol in terms of nonce and session key confidentiality, aliveness, weak agreement, non-injective agreement, and non-injective synchronization.

Published: July 2021

Islamic banking is one of the financial institutions whose activities are financial intermediation between the owners of capital and those who need capital. This study was conducted to know and analyze the impact of inflation as a moderating influence of financial performance on the growth of Islamic banking in Indonesia. The financial performance used consists of return on assets (ROA), non-performing financing (NPF), net operating margin (NOM), capital adequacy ratio (CAR), financing to Deposit Ratio (FDR), and operating expenses for operating income (BOPO). The data used is secondary data, obtained from the results of financial reports published on the official website of the Otoritas Jasa Keuangan (OJK) from January 2015 to December 2019. The analysis results show that, in general, inflation cannot moderate the influence of financial performance on rbanking growth—Sharia in Indonesia. Inflation can only be a predictor of the effect of return On Assets and net operating margin on the growth of Islamic banking in Indonesia. Meanwhile, the variables of non-performing financing (NPF), capital adequacy ratio (CAR), financing to deposit ratio (FDR), and operating expenses for operating income (BOPO) are not able to be a moderator or as a predictor

Published: July 2021

The core of the work is based on the replacement of carbon atoms by silicon atoms, on the basis of four standard bases of DNA: A, C, G and T (adenine, cytosine, guanine, thymine). Determining with minimum computational methods via ab initio Hartree-Fock methods, infrared spectrum and their peak absorbance frequencies. The option for simple replacement of carbon by silicon is due to the peculiar characteristics between both. Atomic interactions under non-carbon conditions were studied, with only the Hydrogen, Silicon, Nitrogen and Oxygen atoms, in CNTP, for the four standard bases of DNA, A, C, G and T, thus obtaining by quantum chemistry four new compounds, named here as: ASi, CSi, GSi and TSi. Computational calculations admit the possibility of the formation of such molecules, their existence being possible via quantum chemistry. Calculations obtained in the ab initio Unrestricted and Restrict Hartree-Fock method, (UHF and RHF) in the set of basis used Effective core potential (ECP) minimal basis, UHF CEP-31G (ECP split valance) and UHF CEP-121G (ECP triple-split basis), CC-pVTZ (Correlation-consistent valence-only basis sets triple-zeta) and 6-311G**(3df, 3pd) (Gaussian functions quadruple-zeta basis sets).

Authors: Hernández Mendoza Dulce Maripaz , San Martín del Ángel Pablo , Jiménez Torres Catya , Hernández Herrera Rosa Idalia
Published: July 2021

Vibrio es un género ampliamente distribuído en ambientes estuarinos y marinos, adaptable y con rápida propagación de sus cepas. Los moluscos bivalvos son reservorios potenciales de Vibrios, su consumo está relacionado con el desarrollo de vibriosis leve como gastroenteritis hasta septicemia grave o la muerte. Por lo cual es importante el monitoreo continuo en las áreas de extraccion y distribución para evaluar el riesgo para la salud humana derivado del consumo de moluscos y garantizar la inocuidad de estos bivalvos. En el presente estudio se determinaron las diferencias estacionales en la presencia y abundancia de Vibrios durante las fases de recolección (bancos ostrícolas) y post-recolección (cooperativas y restaurantes) en ostiones Crassostrea virginica de las lagunas de Tamiahua y Tampamachoco, Veracruz, México. Las muestras fueron obtenidas de trece sitios al azar durante el año 2018. El aislamiento bacteriano se realizó por el método de siembra por dilución en medio TCBS y recuento en placa de acuerdo a la NOM-031-SSA1-1993. El análisis estadístico indicó que no existieron diferencias espaciales significativas, no obstante, se presentaron diferencias estacionales. En esta investigación, se evidencia por primera vez, la presencia de Vibrio spp. en ostiones de las cooperativas de estudio. También se reporta la ausencia de este género bacteriano en los restaurantes adyacentes. En general, los resultados muestran la necesidad de aplicar medidas dirigidas a reducir la presencia de Vibrios durante la fase de post-recolección de ostiones, con la finalidad de disminuir el riesgo de infección por Vibrio spp. en los consumidores.

Le syndrome de Moymoya est une anomalie de l’angiogénèse, souvent responsable d’accidents vasculaires cérébraux par sténose progressive des artères de la base du cerveau. C’est la portion intracérébrale de la carotide interne qui est concernée ; d’où le développement d’un réseau collatéral de suppléance qui donnera l’aspect de « fumée de cigarette ». Les manifestations ischémiques sont fréquentes chez les enfants et les adultes mais les atteintes hémorragiques semblent plus fréquentes chez l’adulte et ne représentent que 10% des atteintes pédiatriques. Le pronostic peut être assombri par le risque de récidives mettant en jeu le pronostic neuro-intellectuel et même vital. Le diagnostic repose sur l’angiographie qui représente l’examen de référence alors que l’angio-IRM peut la remplacer si les lésions sont typiques. Le syndrome de Moyamoya peut être primitif ou secondaire à une autre pathologie dont la recherche étiologique reste primordiale. Nous allons décrire un cas de Moyamoya chez un jeune homme découvert à l’occasion d’AVC ischémiques à répétition dont l’origine toxique semble la plus probable.

Introduction : Nous rapportons un cas de néoplasie endocrinienne multiple de type 2 (NEM2) associé à une mutation du proto-oncogène RET. Objectifs : Rechercher et identifier une mutation du protooncogène RET chez le cas index de NEM2 pour confirmer le diagnostic clinique. Dépister, chez les apparentés, ceux qui portent la mutation familiale pour leur faire bénéficier d’une prise en charge médicale étroite et thérapeutique avant toute manifestation clinique et biologique. Matériels et méthodes : Il s’agit d’une patiente âgée de 18 ans qui présente un cancer médullaire. Un prélèvement sur tube EDTA a été acheminé au laboratoire de Biologie moléculaire accompagné d’une demande d’analyse génotypique du gène RET, d’un arbre généalogique et d’une fiche de consentement. L’extraction d’ADN a été faite par la méthode de précipitation aux sels. L’étude génétique a été réalisée par une amplification des différents exons par PCR suivie d’un séquençage sur ABI 3130 Applied Biosystems. Après avoir retrouvé la mutation chez le cas index, des apparentés ont bénéficiés de l’analyse génétique. Il s’agit du père âgé de 63 ans, de la mère âgée de 58 ans et de la sœur âgée de 22 ans. Résultats : Le cas index présente une mutation au niveau l'exon 11 du proto-oncogène RET. Cette mutation provoque le remplacement de la cystéine au niveau du codon 634 par l'arginine (mutation C634R). Le père, la mère et l’unique sœur qui sont apparemment en bonne santé, ne présentent pas la mutation. Conclusion : Cette mutation a été décrite et retrouvée spécifiquement dans des cas de NEM2A. Cela impose la recherche d’un phéochromocytome et surveillance biologique et médicale. Uniquement la patiente cliniquement affectée est porteuse de la mutation du gène RET. Cela signifie que cette mutation C634R est de novo. Les parents non porteurs de la mutation sont rassurés et il n’est pas nécessaire de faire l’étude génotypique d’autres apparentés sauf si la patiente a des enfants.

Objectifs : Décrire les aspects cliniques et thérapeutiques des urétérohydronéphroses sur ancien terrain de bilharziose dans le service d’urologie du CHU du Point-G. Matériel et méthodes : Il s’agissait d’une étude rétrospective et descriptive réalisée entre 2010 et 2014 sur tous les malades présentant une urétérohydronéphrose avec un antécédent de bilharziose traités au service d’urologie du CHU du Point-G. Les patients perdus de vue lors de l’étude n’ont pas été inclus. Résultats : Nous avons colligé 25 cas d’urétérohydronéphrose sur antécédent de bilharziose urinaire. L’âge moyen de nos patients a été de 36,1 ans avec des extrêmes de 10 et 62 ans. Le sexe masculin était le plus représenté soit 56,0%. Ségou était la région la plus représentée avec 28,0% des patients, suivie de Kayes et de Bamako. La douleur lombaire a été le motif de consultation le plus fréquent soit 64,0%. Tous nos patients avaient un antécédent de bilharziose urinaire. La notion de traitement traditionnel ressortait chez 13 patients. La recherche des œufs de bilharzies sur les urines et sur la biopsie de la muqueuse rectale était positive respectivement dans 36,0 % et 20,0%. La cystoscopie a mis en évidence des lésions bilharziennes soit à type de plages congestives, soit de granulations ou de tapis sableux. L’UIV a mis en évidence une urétérohydronéphrose bilatérale dans 10 cas. La réimplantation urétérovesicale directe fut réalisée chez 22 patients et une néphrectomie chez 3 patients. Nous avons enregistré un décès. Conclusion La prise en charge précoce de la bilharziose urinaire pourrait prévenir certaines urétérohydronéphroses et leur retentissement sur la fonction rénale.

Published: July 2021

Le syndrome douloureux régional complexe type1 (SDRCI) ou algodystrophie est défini comme un syndrome douloureux vasomoteur et trophique portant sur des structures sous-cutanées, articulaires, périarticulaires et osseuses, d’un segment de membre, le plus souvent après un traumatisme. Sa physiopathologie est complexe et n’est pas totalement élucidée. Elle implique un dysfonc-tionnement sympathique, des phénomènes inflam-matoires, neurogéniques, vasculaires, périphériques et centraux. L’incidence du SDRC I est forte entre 30 et 70 ans et la majorité des travaux rapportent la prédominance féminine. Les facteurs favorisants sont nombreux, mais dans certains cas, aucune cause n’est retrouvée. Sur le plan clinique, différentes phases caractérisent le SDRCI, la phase aigüe dite chaude douloureuse, la phase dystrophique caractérisée par l’amplification des troubles trophiques et la phase atrophique qui se confond parfois avec la 2ème et au cours de laquelle s’installent les attitudes vicieuses, pouvant devenir des séquelles permanentes. Le diagnostic est clinique et les examens biologiques dont le bilan inflammatoire sont habituellement sans anomalies. Des critères diagnostiques cliniques sont actuellement établis et validés sur le plan international. L’hyperfixation osseuse au technétium 99 précède l’apparition des signes radiologiques, mais elle peut totalement manquer chez l’enfant et l’adolescent. L’IRM n’a de place qu’en cas de difficulté diagnostique, particulièrement en cas d’atteinte de la hanche. Le traitement de SDRC de type I est n’est pas bien défini. La kinésithérapie, la physiothérapie sont essentielles. Pendant la phase douloureuse, les antalgiques de palier 1 et 2 sont utiles. La corticothérapie en cure courte a donné des résultats favorables. La calcitonine, considérée pendant longtemps comme le traitement de référence de l’algodystrophie, n’est plus recommandée. Les bisphosphonates ont un effet antalgique mais leur prescription reste hors AMM. La place de l’anesthésie thérapeutique dans les formes d’algodystrophie réfractaire reste à définir. Les blocs sympathiques sont remis en cause, la sympathectomie est rarement pratiquée. La prise en charge psychologique est indispensable et la prévention reste essentielle.

Le cancer représente la deuxième cause de mortalité dans le monde. Sa prise en charge est multidisciplinaire dont la part du biologiste est non négligeable. Le dosage des marqueurs tumoraux sériques permet d’identifier dans le sang des substances pouvant indiquer la présence d’un cancer. En pratique médicale, on assiste souvent à des prescriptions fréquentes du dosage de marqueurs tumoraux et qui ne sont pas toujours appropriées, entrainant ainsi un surcout financier important. Dans cet article, sont passés en revue les points particuliers concernant les dosages des marqueurs tumoraux sériques : classification, indications et intérêt de la prescription, ainsi que les bonnes pratiques que chaque médecin doit connaitre et bien maitriser.

Published: July 2021

We can see a person standing in front of our house from electricity board, whose duty is to read the energy meter and handover the bills to the owner of that house every two months. This is nothing but meter reading. According to that reading we have to pay the bills. The main drawback of this system is that person has to go area by area and he has to read the meter of every house and handover the bills. Many times errors like extra bill amount, or notification from electric board even though the bills are paid are common errors. To overcome this drawback we have come up with an idea which will eliminate the third party between the consumer and service provider, even the errors will be overcome. The idea of smart energy meter using IOT and Arduino has been introduced. In this method we are using Arduino because it is energy efficient i.e. it consume less power, it is fastest and has two UARTS. In this paper, energy meter which is already installed at our houses are no t replaced, but a small modification on the already installed meters can change the existing meters into smart meters.

SELECTION OF SHORT STATURE AND EARLY MATURING BADSHAH BHOG IN M2 FROM GAMMA RAY IRRADIATION
Authors: Imam Zafar , Chakraborty Nihar Ranjan , Gadi Jarman
Published: July 2021

Badshah Bhog is a non basmati aromatic traditional rice cultivar. which is not widely cultivated due to some unfavourable traits which were relatively high plant height, late maturity and low average yield. By the utilization of gamma ray irradiation in plant breeding attempted to overcome such problems in crops. The objective of this research is to observe and select M2 mutants of Badshah Bhog from gamma ray irradiation and obtain early maturing short stature plants. The research was conducted by Line sowing method. Established experimental plots for every irradiation doses and comparing the treatment result with the control to identify the effect of irradiation on the growth of Badshah Bhog. The result showed that there have been several plants with potential mutant traits supported the positive and negative character of every individual. The irradiated dose of 300 Grays has the shortest maturity duration of 131 days with the highest productive tiller of 6.67 but very low as compared to control. The irradiated dose of 400 Grays has the shortest Plant height of 97.8 cm. The plant yield of mutant lines in the present study was not affected significantly in any direction which could due to occurrence of polygenic mutations with ‘plus’ and ‘minus’ effect equally distributed. Together with short stature plants also plants bearing double spikelet at tip and mid region of panicle observed.

Published: July 2021

River-breeding foothill yellow-legged frogs (Rana boylii) are endemic to California and Oregon. Across this wide geographic range, many populations have declined due habitat loss, non-native competitors and predators (e.g., American bullfrogs [Lithobates catesbeianus], Centrarchid fish), and disrupted water flow due to dams. Even when flow conditions are not extensively regulated, managers still require basic and region-specific information about the breeding biology of this species to prevent further decline. To document spatiotemporal dynamics of reproductive output during drought and high flow years, we surveyed a 13.5 km reach of the lower Mad River, Humboldt County, CA approximately 70 km downstream of Matthews Dam. We found relatively high densities of egg masses (39 to 59 masses / km). Egg masses were generally laid on small cobbles (mean ±SE diameter = 11 ± 0.24 cm) at depths between 0 and 20 cm, and 95% of egg masses were laid within 6 m of the wetted edge. Egg masses were disproportionately found in the tailouts of fast runs and glides, and found less often than expected in side arms, runs, and riffles than would be expected by chance. Breeding timing appeared to be more related to rapid decreases in stream flow variance than air temperature. Taken with previous information about the species, our results suggest that R. boylii rely on multiple cues to initiate breeding. Our results can be used to help inform breeding timing and habitat use by R. boylii breeding under natural flow regimes in Northern California. Our recommendations for future research include further investigating upland habitat use by post-metamorphic life stages factors that influence breeding site selection.
Current status of the Mohave ground squirrel: an update covering the period 2013–2020
Authors: Leitner Philip
Published: July 2021

The Mohave ground squirrel (Xerospermophilus mohavensis) is endemic to the western Mojave Desert of California. It is restricted to a small geographic area and is listed as Threatened under the California Endangered Species Act. Human development has resulted in loss and degradation of its desert habitat and climate change is believed to pose an additional threat. To determine its current conservation status and geographic distribution, I have assembled all available data from field studies during the years 2013-2020. These data confirm that the species is still present in 4 core areas and that it continues to be widespread in the northern and central portions of its historical range. However, the recent data also confirm earlier conclusions that the Mohave ground squirrel is now extirpated from the southernmost portion of its range. Recent surveys raise concerns about its status in other areas as well. A large-scale trail camera survey on the South Range unit of China Lake Naval Air Weapons Station in 2019 failed to detect the Mohave ground squirrel over much of this large installation. Recent trail camera surveys on Fort Irwin strongly suggest that the closely-related round-tailed ground squirrel (Xerospermophilus tereticaudus) has now replaced the Mohave ground squirrel over most of the base. There is additional evidence that the round-tailed ground squirrel is present in disturbed habitats to the west of Barstow and that hybridization with the Mohave ground squirrel is occurring there. It will be important to protect and conserve currently occupied Mohave ground squirrel habitat in view of this new information.
The explicit integration of Species Conceptual Models and Species Distribution Models as a best practice for systematic conservation planning in California
Authors: Parisi Monica D. , Greco Steven E.
Published: July 2021

Natural Community Conservation Plans (NCCPs) represent the most powerful tool in statute for regional and systematic conservation planning for species at risk in California. This study examines the use of species conceptual models (SCMs) and species distribution models (SDMs) in such planning. Eighteen Natural Community Conservation Plans (NCCPs) were analyzed to determine if or how explicit connections were made between both types of models for a covered species and key components of its conservation strategy. Results indicate plans were strong in the use of SDMs, however, each deferred preparing or using SCMs to later management and monitoring phases. A more effective best planning practice for developing a conservation strategy is to explicitly integrate SCMs and SDMs during plan preparation.

San Joaquin kit foxes (Vulpes macrotis mutica) are federally endangered and California threatened, primarily due to profound habitat loss. Kit foxes are obligate den users and in some locations den availability may be limited due to natural or anthropogenic factors. We conducted a study during 2001–2004 to determine whether kit foxes would use artificial dens, and if so, whether they exhibited a preference for den designs or construction materials. We tested six different den designs, four different construction materials, and two different chamber types. We constructed 34 dens in 12 locations in Bakersfield, CA. We conducted 9,271 den checks and detected kit foxes or their sign on 1,198 of those checks. Kit foxes may not have found one of the locations, but kit foxes used (i.e., entered) 29 of the 31 dens at the other 11 locations. Kit foxes did not exhibit preferential use of any designs, materials, or chamber types. Internal conditions (i.e., temperature and relative humidity) within artificial dens can provide thermoregulatory and moisture conservation benefits to foxes, although these benefits were not as strong as those provided by natural dens. At least nine other species were documented using the artificial dens, including some that might compete with kit foxes. San Joaquin kit foxes readily used artificial dens and clearly such dens can be used to mitigate den losses or to enhance habitat for kit foxes. Due to lower cost and ease of installation, we recommend installing two-entrance dens constructed of high-density polyethylene plastic with an irrigation valve box for a subterranean chamber.

Proposta Metodológica Grupo Focal Educação Ambiental vertentes filosóficas e teóricas
Authors: Ribeiro Fernando da Costa
Published: July 2021

Este Material Pedagógico foi utilizado na palestra sobre “A Pesquisa Científica com Abordagem em Educação Ambiental”, na Oficina de Métodos e Técnicas de Pesquisa em Ciências realizada pelo Curso de Licenciatura em Ciências Naturais da Universidade do Estado do Amapá-UEAP, em dezembro de 2017.

O presente trabalho discorre sobre a Proposta Metodológica do Grupo Focal e como aplicar essa metodologia na Educação Ambiental vertentes filosóficas e teóricas.

O Grupo Focal-GF é um método de pesquisa qualitativa que reúne participantes em uma entrevista, na qual expõem opiniões sobre produtos ou serviços. É um tipo de pesquisa muito usada na área de Educação.

Algumas pessoas confundem grupos focais com entrevistas ou simples conversas informais. Porém, esse conceito está errado. Este Material é para que você saiba como esses grupos realmente funcionam e de que maneira são aplicados em estratégias para coletar, transcrever, tabular e analisar dados qualitativos na área educacional.

O principal objetivo do GF é reunir informações detalhadas sobre um tópico específico (sugerido por um pesquisador, coordenador ou moderador do grupo) a partir de um grupo de participantes selecionados. O GF busca colher informações que possam proporcionar a compreensão de percepções, crenças, atitudes sobre um tema, produto ou serviços.

Costuma reunir em torno de 5 a 12 pessoas e conta sempre com um moderador que lidera a discussão cujo tempo de duração pode variar de meia hora a uma hora e meia.

Assim, o moderador é o responsável por listar as perguntas e compartilhá-las com o grupo para que todos possam responder. A quantidade de perguntas pode variar de 10 a 15, sendo que elas têm o propósito de levantar as opiniões e ideias de cada participante.

Os grupos focais não são conversas informais como as que temos com um grupo de amigos. Por isso, é necessário conduzir a discussão pelo caminho certo, com foco no objetivo. Esse trabalho é feito pelo moderador.

As discussões no GF são válidas se forem utilizadas com cuidados para estudar um problema em que é adequada a utilização desta técnica.

No que diz respeito à questão da validade são muito semelhantes a outras formas de ciências sociais da investigação, em que a validade depende não só dos procedimentos utilizados, mas também do contexto, neste caso, devem ser levados em conta, a localização, o tipo de conversa, as reflexões.

New correction method for the scattering coefficient measurements of a three-wavelength nephelometer
Authors: Qiu Jie , Tan Wangshu , Zhao Gang , Yu Yingli , Zhao Chunsheng
Published: July 2021

Abstract. The aerosol scattering coefficient is an essential parameter for estimating aerosol direct radiative forcing and can be measured by
nephelometers. Nephelometers are problematic due to small errors of nonideal Lambetian light source and angle truncation. Hence, the observed raw
scattering coefficient data need to be corrected. In this study, based on
the random forest machine learning model and taking Aurora 3000 as an
example, we have proposed a new method to correct the scattering coefficient
measurements of a three-wavelength nephelometer under different relative
humidity conditions. The result shows that the empirical corrected values
match Mie-calculation values very well at all three wavelengths and
under all of the measured relative humidity conditions, with more than 85 %
of the corrected values having less than 2 % error. The correction method
obtains a scattering coefficient with high accuracy and there is no
need for additional observation data.
Latrine Utilisation and Associated Factors in Southern Ethiopia: Evidence from Selected Households in Holte Town, Ethiopia
Authors: Haligamo Demamu Tagele
Published: July 2021

Globally, over 2.5 billion people are still without access to improved sanitation. Almost a third of the world’s population suffers on a daily basis from a lack of access to a clean and functioning toilet. People are obliged to defecate in the open due to a lack of toilet facilities. Poor usage of latrines and excreta disposal are contributing factors to a high number of morbidity and mortality, especially among under-five children. Health improvement comes from proper sanitation facilities, not simply because of their mere physical presence. Therefore, this study assessed latrine utilisation and associated factors among households in Holte town of Derashe, especial Woreda, southern Ethiopia. A cross-sectional study was conducted on 356 households using an interviewer-administered questionnaire and checklist. An SPSS software Version.23 was used for analysis, and descriptive statistics and association among factors were finally calculated. From total respondents, 316 (88.76%) were using Latrine for 24 hours (good utilisation), 29 (8.1%) daily and the remaining 11 (3.0%) rarely (poor utilisation). Family members in each household were identified as using Latrine together. From the study respondents who have under-five children, 189 (53.1%) of the households do not allow their children to use Latrine. In conclusion, there is somewhat good latrine utilisation but poor hand washing practice after visiting Latrine in the study area. So, strengthening health information dissemination, appropriate technical support, and multi-sectorial collaboration should be key factors to improve the proper utilisation of latrines and handwashing practices.

STATISTICS: YOUR TICKET TO ANYWHERE
Authors: BILGIN AYSE AYSIN BOMBACI , BULGER DAVID , FUNG THOMAS
Published: July 2021

“We have too many first-year statistics students but too few who choose to major in statistics” is a common complaint among academics in the discipline of statistics, and our department is no exception. Many non-statistics academics appreciate the value of statistics to their discipline and include at least one statistics unit in their required units. However, students in such units often do not see the use of statistics within their discipline or the importance of learning statistics or quantitative skills in general, despite the current shortage of statisticians and deluge of data to be analysed. Our student numbers decline sharply by years of study, from first to second and from second to third. A handful of students who decide to major in statistics or decision science find themselves in high demand. In early 2016, just before the first semester started, we ran an event for the previous year’s successful first-year statistics students to encourage more students to choose statistics or decision science as a second major in addition to their existing majors. We worked with our alumni so that the second-year students heard talks mainly by people like them instead of like us – their lecturers. We called this event ‘Statistics: Your Ticket to Anywhere’. In this paper, we describe how we structured the event, its outcomes for the department, and how it helped us to “unveil the curtain” and to show the value of statistics to the students in their chosen fields of study.

STATISTICS EDUCATION THAT INSPIRES LONG-TERM RETENTION OF LEARNING – A QUALITATIVE MODEL
Authors: SOWEY ERIC R.
Published: July 2021

Statistical methods are an indispensable partner in all scientific work and in many other professional and commercial fields. So it is not surprising that statistics is widely studied at university. Yet most students never complete more than a single course in the discipline – and that is usually early in their studies. In this situation especially, it makes sense that teaching should aim at inspiring students to retain their learning for the long term. Here the author presents a comprehensive qualitative model of education designed for this goal. The model translates readily into practice and this is demonstrated by bridging it to a rich set of workable tools that are drawn from related papers by the author.

ENGAGING SCHOOL STUDENTS AND EDUCATORS WITH THE PRACTICE OF STATISTICS
Authors: HOWLEY PETER , ROBERTS TIM
Published: July 2021

This paper describes a national statistics-oriented project-based learning activity, which has been delivered annually for five years in Australia and the outcomes of a particular collaboration of this initiative with the discipline of environmental sustainability. The national initiative engages primary- and secondary-school students from varied backgrounds and education levels in quantitative-based investigations. It develops key future workplace skills aligned with national school-curriculum outcomes and motivates students by enabling them to take the lead, determine the context, collaborate, investigate, and create. An underlying delivery model connects primary- and secondary-school students with tertiary educators, industry, and the practice of statistics. A pre-post cross-sectional study revealed significant improvements in students’ and teachers’ confidence with, and awareness of, the field of statistics. Australian school teachers are saying, “21st Century learning at its best” and “motivates and engages students.” Industry mentors are saying, “provides students a unique opportunity.” Students are saying, “engaging, educational and enjoyable.” The activity has engaged some eighty schools, and annually several hundred students participate.
