Performance Grading

This study reviewed new concept waterproofing performance gradation to respond to the limit of unified single standard performance standard used in each country from the past until now. This study was carried out using the standard test data from 34 products tested and evaluated by Korea’s national quality test institution for 2 years (2018~2019) based on national standard specification (KS F 4934, Self-Adhesive Rubberized Asphalt Sheet). Major proposal contents utilized the result values of 9 waterproofing performance evaluation criteria included in the national standard specification. Major study contents and results are as follows. Existing widely used domestic and overseas standard grading (Stanine, Sten Scores, Grade 5 Scale, energy consumption efficiency, and other grading) theories were investigated and analyzed. Based on the analysis contents, standard Grade 5 Scale system suitable for waterproofing material performance grading was selected and applied. Grade sections were set according to the application ratio for each grade section of Grade 5 Scale (grade 1 with 10%, grade 2 with 20%, grade 3 with 40%, grade 4 with 20% and grade 5 with 10%). According to the set sections, performance grades were derived for 9 test criteria of 34 products. Section setting standard for grade section was derived centered on the performance result values of 9 criteria. As a result, average value of waterproofing performance of each of 9 test criteria for 34 products was verified to have 1.2 times to 7.52 times higher performance value than the minimum quality standard (based on grade 5). Such results sufficiently showed the limit of the current unified single standard performance application. Also, as a solution for waterproofing quality degradation problem, possibility to apply the waterproofing performance grading of this study was verified. Therefore, through this study, it is decided that new concept quality standard to pursue future waterproofing industry development can be set, quality reinforcement is possible by performance grading for each product and sustainable waterproofing performance maintaining effect at the waterproofing construction site can be expected with the use of such gradation.

An important milestone in early childhood education and care is reached in 2021 as Belonging, Being and Becoming: The Early Years Learning Framework for Australia is reviewed. The Early Years Learning Framework (EYLF) was groundbreaking. It has been influential in providing national guidelines around pedagogical principles, practice and learning outcomes for children. This commentary is intended to contribute to the wider conversation that is taking place this year. It proposes that a refined EYLF retains the focus on child-centredness and playful learning, and advocates for the structure of the revised document to include continua of learning and development. The provision of learning trajectories would assist early childhood educators to enact the planning cycle, meet National Quality Standard Quality Area 1, and thus potentially increase the learning outcomes for all children.

A amostra consiste em 257 unidades de ECEC em três estados australianos. Os resultados indicaram: associações positivas modestas entre as pontuações do NQS e das escalas; alguma especificidade entre as áreas de qualidade do NQS (aspectos do projeto e práticas pedagógicas para as crianças; relações com crianças) e de uma escala de avaliação – a SSTEW; variabilidade das pontuações das escalas de qualidade dentro de cada classificação do NQS; e atenuação dessas associações quando  o tempo  entre  as avaliações  ultrapassa  24 meses. As conclusões sugerem que o NQS e as escalas de avaliação indicam um núcleo comum de qualidade, mas capturam aspectos diferentes da qualidade, sugerindo que ambos poderiam ser usados para melhorar os padrões de qualidade nas pré-escolas australianas, onde as escalas de avaliação potencializam a qualidade ainda mais do que o NQS.</p><p><strong>Palavras-chave:</strong> National Quality Standard, ECERS-E, SSTEW, Qualidade, Pré-Escola, Regulamentação</p><p> </p><p><strong>Comparando índices regulatorios y no regulatorios de calidad de la educación infantil en Australia</strong></p><p>Este estudio analiza las asociaciones entre los puntajes provenientes de procesos regulatorios   de evaluación de la calidad de la educación infantil australiana (Early Childhood Education and Care – ECEC) del National Quality Standard (NQS) y de las dos escalas de evaluación de calidad (SSTEW – Sustained Shared Thinking and Well Being; y ECERS-E – Early Childhood Environment Rating Scale-Extended).

There has been a fast-growing demand for cybersecurity professionals to defend cyber space and information systems. With more and more programs and course offerings in cybersecurity popping up in higher education, it is important to have a consistent and reliable quality standard to guide and evaluate the training and preparation of qualified cyber defense workforce. The national Centers of Academic Excellence in Cyber Defense Education (CAE-CDE) designation program jointly sponsored by the US National Security Agency (NSA) and Department of Homeland Security (DHS) is a rigorous national standard with specific criteria for maintaining the quality of cybersecurity education. This article explains the CAE-CDE program criteria and requirements and discusses the important role of the special designation in improving cyber defense education and workforce development. This article illustrates the educational value and quality impact of the CAE-CDE program with three case studies: (1) University of Missouri – St. Louis; (2) American Public University; and (3) Robert Morris University.

Regime Of Truth

IN THIS ARTICLE WE use feminist post-structuralist concepts of discourse and relations of power to question how a neoliberal regime of truth in Australian early childhood education impacts educators currently working for gender equity with children, prior to their entry to schooling. We show how this regime of truth is endorsed and transferred in and by key documents of the Australian National Quality Framework (NQF) including the National Quality Standard (NQS) and the Early Years Learning Framework (EYLF) in which discourses of universal rights, individual freedom and choice, and human capital dominate approaches to inclusion and diversity that govern gender equity work (ACECQA, 2011, 2017a, 2017b; DEEWR, 2009; NSW Education, 2016). Our article addresses how some educators use their understandings of feminism to negotiate spaces for gender equity work within the theoretical, political and ethical tensions arising in/between discourses that constitute this neoliberal regime of truth.

Children's Activities

Compelling evidence links childhood experiences in quasi-natural settings with learning and wellbeing, but, as cities grow, children's activities have been increasingly restricted to de-natured spaces that are designed or controlled by adults. In recent years, academics and education practitioners have campaigned to reverse this trend, and one result is that Australian early childhood centres and schools increasingly provide environments that enhance opportunities for children to engage with nature. These moves are also underpinned by higher-level policy initiatives. For example, the National Quality Standard, Element 3.2.1, requires that early childhood outdoor spaces are designed so that children experience natural environments (ACECQA, 2013). Similarly, the South Australian Department for Education and Child Development (2016, p. 5) Outdoor Learning Environments Standard mandates ‘balanced environments which instil a sense of wonder, generate curiosity and spark the imagination of children and young people’. However, despite recent interest and policy initiatives, the processes by which environments influence learning remain ‘under-researched’ (Engelen et al., 2013, p. 324) and constitute a ‘significant blind spot’ (Rickinson et al., 2004, p. 8) in the literature.

Node Count

As with other malignancies, lymph node metastasis is an important staging element and prognostic factor in colorectal carcinomas. The number of involved lymph nodes is directly related to decreased 5-year overall survival for all pT stages according to United States Surveillance, Epidemiology, and End Results (SEER) cancer registry database. The National Quality Forum specifies that the presence of at least 12 lymph nodes in a surgical resection is one of the key quality measures for the evaluation of colorectal cancer. Therefore, the harvesting of a minimum of twelve lymph nodes is the most widely accepted standard for evaluating colorectal cancer. Since this is an accepted quality standard, a second attempt at lymph node dissection in the gross specimen is often performed when the initial lymph node count is less than 12, incurring a delay in reporting and additional expense. However, this is an arbitrary number and not based on any hard scientific evidence. We decided to investigate whether the additional effort and expense of submitting additional lymph nodes had any effect on pathologic lymph node staging (pN). We identified a total of 99 colectomies for colorectal cancer in which the prosector subsequently submitted additional lymph nodes following initial review. The mean lymph node count increased from 8.3 ± 7.5 on initial search to 14.6 ± 8.0 following submission of additional sections. The number of cases meeting the target of 12 lymph nodes increased from 14 to 69. Examination of the additional lymph nodes resulted in pathologic upstaging (pN) of five cases. Gross reexamination and submission of additional lymph nodes may provide more accurate staging in a limited number of cases. Whether exhaustive submission of mesenteric fat or fat-clearing methods is justified will need to be further investigated.
