The Utilization OpenCV to Measure the Water Pollutants Concentration

<strong>Abstract. </strong>Intensive water quality determination needs to be adjusted with technological developments to meet today's society's needs and increased water pollution due to urbanization. Therefore, early detection is essential for in site water quality determination and as a critical consideration in making health and environmental decisions. OpenCV is a library programming feature for Computer Vision which focuses on extracting information from images in real-time, this can be considered to be potential to measure the pollutant concentration. <strong>Objectives:</strong> This study identify the potential of colorimetry analysis method by using OpenCV as an alternative method for pollutant concentration measurement<strong>. Method and results:</strong> First stage, this study collecting the data of NH3 phenate and Pt-Co CU from the spectrophotometer. The first stage also was including the development of an OpenCV code. Then, the data was collected were processed to get the concentration of NH3 and Pt-Co both using OpenCV and spectrophotometer; factors that influence the Pt-Co sample image measurement process by using OpenCV-Python was analyzed too. Then in the analysis stage, the result of the two measurement method was tested by statistic determine its significant difference. The conclusion found whether OpenCV could be potential to measure the pollutant concentration or not. <strong>Conclusion:</strong> the OpenCV has potential to be use as alternative colorimetry measurement method to determine water pollutant as there is no significant difference in the spectrophotometric method results and the results from OpenCV for Pt-Co sample. Meanwhile, in this study found that the result of NH3 from spectrophotometer is nonlinear different with from OpenCV that is linear. Thus, further research is needed to test the validity of OpenCV method. The factor influence of measurement using OpenCV code is when determining the Region of Interest (ROI) and determining the pixel values for the normalized box filter

Some Thoughts Evoked by Peter Lor, Bradley Wiles, and Johannes Britz, “Re-thinking Information Ethics: Truth, Conspiracy Theories, and Librarians in the COVID-19 Era,” in LIBRI, March 2021

The paper offers some thoughts prompted by the research paper published by Peter Lor, Bradley Wiles, and Johannes Britz, “Re-Thinking Information Ethics: Truth, Conspiracy Theories, and Librarians in the COVID-19 Era,” in LIBRI, March 2021. It highlights two significant contributions, an analysis of the misinformation in the COVID-19 pandemic and the notion of alethic rights, the right of truth of patrons based on the work of D’Agostini. This reflection then situates the COVID-19 misinformation campaign within the broader disinformation ecology within which it exists. While it agrees that alethic rights are an important ethical framework, it wonders whether it practically advances work beyond that libraries and librarians are already doing, e.g., in collection decisions, approaches to reference questions, or library programming. It looks at the debate between John Swan and Noel Peattie on the inclusion of books representing outright lies in the collection (e.g., Holocaust denial). It then contrasts a right to information and authorities propagating and validating that information with a right to misinformation and authorities for propagating and validating that misinformation that exists within disinformation ecologies. The problem of truth, its authorities and its context appears to be more complicated than an appeal to alethic truths: for example, liberals and conservatives differ on the meaning of a rational consensus on contentious political matters, such as climate change. Given the dire consequences of misinformation on democracies and public health, an appeal to professional neutrality is woefully inadequate. There must be proactive resistance, if not outright repudiation.

Bonded design in the virtual environment: the transition of a participatory design methodology

PurposeThis paper examines how bonded design (BD), a participatory design methodology, was influenced by the transition to working in a virtual environment necessitated by the coronavirus disease 2019 (COVID-19) pandemic.Design/methodology/approachAbiding by the participatory design tenets of creativity, learning-by-doing and mutual learning, the BD methodology was created for the specific purpose of fostering meaningful communication and interaction between two disparate groups. Previous iterations of BD are discussed, including its naissance with intergenerational teams, its adaptation to provide a framework for a university-wide initiative, the Faculty Information Technology (IT) Liaison Program that brought together faculty members and IT professional staff, and its current use in helping public librarians to develop with older adults, targeted library programming and services.FindingsAnalysis of the findings from the assessment of the BD methodology in different physical contexts demonstrates that the flexibility in the makeup and order of design techniques (discussion, evaluation, brainstorming, prototyping, consensus-building) makes BD potentially adaptable to online spaces. Recommendations for implementing the BD methodology online are outlined. It is argued that BD’s adaptability makes it an ideal method for creating meaningful and productive collaborations within both physical and virtual environments.Originality/valueThe proposed iteration of the BD methodology responds to a need for innovative practices to foster collaborative work in a virtual environment. BD is a unique, inclusive and cost-effective methodology to encourage meaningful interaction and communication between disparate groups in physical or online contexts.

Reimagining public library programming during a pandemic

This article uses survey data to describe, discuss, and examine the ways in which small and rural public libraries adjusted their programming during the COVID-19 pandemic. The restrictions associated with the pandemic forced libraries to close their doors and reimagine how they would deliver programming to their community.

Educating and Empowering Teen Activists in Public Libraries: A Case Study of the Impact of Reading on Young Adult Social Justice Actions

This participatory case study, which consisted of a co-designed virtual program through the Camrose Public Library, investigates how teen readers engage with the social justice themes in YA fiction, how and if they find these themes useful for understanding and engaging in activism on their own, and the influence of public library programming on these actions. I approached my research from a teen-centred perspective, inviting the youth who participated to make adjustments to each stage of the process. My research design, data collection, and data analysis were informed by critical ethnography as theory and reader-response theory. This case study found that, on their own, neither social activism narratives nor library programs motivate teens to conduct social justice actions; instead, they contribute to a network of learning opportunities and information that leads to teens becoming motivated to make a difference in their communities. Thus, public libraries can provide teen programming that uses social activism narratives and collaborative discussions to teach teens more about social justice issues, show them how to get involved in social justice movements, and instill in them the confidence to do so.

Focusing the library on the reader

This study examined the effect of orientating library programming around the reading of manga by special education students in a secondary school. Data was collected through observation, student and teacher interviews, and videotaping student discussions of two novels. A social community of readers was established that altered student behaviour and views of reading.
