There is increasing concern for workers facing multiple chemical exposure. The accumulation of information on occupational conditions indicates the need to incorporate the concept of multiple exposures in the risk assessment process and to develop tools for assessing the potential impacts of multiple exposures on workers’ health. Our objective is to describe the MiXie online decision-making tool that can be used to assess the risk of exposure to multiple chemicals. The description includes the development of MiXie, the structure of its toxicological database according to the target organ or the mode of action, and the algorithm for quantitative analysis of a mixture. Two case studies of its use in evaluating the risks of multiple exposures in real workplace situations are presented. The case study in the printing industry showed increased risk for four toxicological classes (central nervous system damage, ocular damage, skin damage, and ototoxicity) associated with co-exposure to four chemicals during maintenance operations. The MiXie analysis also showed the presence of carcinogenic substances in the mixture and a risk to the development of the foetus. The case study in nail salons showed the presence of carcinogenic and sensitizing chemicals and an increased risk to upper airways. MiXie helps preventers evaluate the possible additive effects of mixtures, providing an easy-to-read diagnosis to identify risks incurred by co-exposed employees. In addition, MiXie identifies risky occupational situations that would go unnoticed without a multiple substance approach.

Outcome-based-education (OBE) is an educational theory that bases each part of an educational system around goals (outcomes). Pakistan Engineering Council (PEC) introduced the OBE in Pakistani engineering higher-education-institutions (HEIs),from 2018, in the replacement of previously followed Syllabus& Curriculum based education system. Key to success of OBE System is its continuous-quality-improvement (CQI) mechanism. The CQI mechanism design should be based on accurate assessment process and flawless evaluation of OBE System parameters; otherwise the OBE System’s benefits cannot be achieved. However, some HEIs have not devised an effective CQI mechanism and they still using classical procedures and academic tools in implementation of the OBE Framework, which cannot give desired results from the new System. This paper presents that; instead of presently employed loose-control, a modified stringent control strategy for academic activity and employment of latest technology, can make the CQI mechanism, more effective and efficient. This paper therefore presents a two-fold contribution. At first, the implementation problems of the OBE System are critically analyzed. Secondly, few modifications in the existing approaches have been introduced to achieve the desired results from the recently adopted OBE system.

Chemical pathology (clinical chemistry/biochemistry) is the branch of laboratory medicine concerned with the detection of alterations in the chemical constituents and biochemical mechanisms, which ensure health, culminating in disease. The disease itself is a pattern of response to some insult or injury resulting in a disturbed function or structure. It is often difficult to ascertain precisely the point of transition from health to a disease state. Pathological changes, including metabolic and molecular perturbations, with the potential to progress to clinical disease, are also present in healthy populations, noteworthy are the reactive oxygen species such as hydroxyl radicals with the propensity to cause oxidative DNA damage. Biochemical profiles or panels such as liver function tests, renal function tests, bone profile, lipid profile, acid-base, and critical care have served as biomarkers employed in indicating the presence of or measuring the progress of the disease, as well as the effect of treatment. Oxidative stress, an imbalance between bio-available antioxidants and reactive species, is now widely recognized as accompanying most pathological states. Hence, the exclusion of antioxidant components in biochemical profiles appears a grave oversight. Basic components of the antioxidant system, glutathione (GSH), zinc, uric acid, ascorbic acid, and α-tocopherol, may be selected for incorporation. GSH is particularly important; as a scavenger for damaging oxidative intermediates in cells, it promises to be a good predictor of disease progression and prognosis. Including the antioxidant component into traditional profiles may aid physicians in more confidently ruling out disease, enabling further investigations, and/or reassuring patients. It is proposed that redefining the traditional profiles in chemical pathology by incorporating the indexes of the antioxidant system promises considerable improvement in the risk assessment process, in disease detection and recognition of the threshold of clinical concern in disease management and biotherapy.

The global demand for acrylic acid (AA) is increasing due to its wide range of applications. Due to this growing demand, alternative AA production strategies must be explored to avoid the exacerbation of prevailing climate and global warming issues since current AA production strategies involve fossil resources. Investigations regarding alternative strategies for AA production therefore constitute an important research interest. The present study assesses waste apple pomace (WAP) as a feedstock for sustainable AA production. To undertake this assessment, process models based on two production pathways were designed, modelled and simulated in ASPEN plus® software. The two competing production pathways investigated included a process incorporating WAP conversion to lactic acid (LA) prior to LA dehydration to generate AA (denoted as the fermentation–dehydration, i.e., FD, pathway) and another process involving WAP conversion to propylene prior to propylene oxidation to generate AA (denoted as the thermochemical–fermentation–oxidation, i.e., TFO, pathway). Economic performance and potential environmental impact of the FD and TFO pathways were assessed using the metrics of minimum selling price (MSP) and potential environmental impacts per h (PEI/h). The study showed that the FD pathway presented an improved economic performance (MSP of AA: USD 1.17 per kg) compared to the economic performance (MSP of AA: USD 1.56 per kg) of the TFO pathway. Crucially, the TFO process was determined to present an improved environmental performance (2.07 kPEI/h) compared to the environmental performance of the FD process (8.72 kPEI/h). These observations suggested that the selection of the preferred AA production pathway or process will require a tradeoff between economic and environmental performance measures via the integration of a multicriteria decision assessment in future work.

Self-assessment has a direct impact on students’ achievement. Through self-assessment students have the opportunity to assess themselves in regards to learning goals and assess their achievement. The purpose of our research is to reflect on the use of the self-assessment practices of students in schools, as well as the impact that student self-assessment has on their achievement. Another purpose of this research is to evaluate if students compare their knowledge with other students in the class and to evaluate if students during the self-assessment process can overestimate or underestimate themselves. Two hundred and two students, from four classes of seventh grade (n=112) and four classes of eighth grade (n=90) of lower secondary schools from five urban schools and five rural schools in Kosovo, in the subject Civic Education, participated in the research. The results show that there is a significant difference between seventh-graders and eighth-graders on the use of student self-assessment. There is also a difference between schools in the city and schools in the village. There is a significant difference between classes and based on residence even when the students are asked if they are encouraged to have self-confidence and be independent.   Received: 13 October 2021 / Accepted: 26 November 2021 / Published: 3 January 2022

Assessment is a crucial aspect of any teaching and learning process. New tools such as educational games offer promising advantages: they can personalize feedback to students and save educators time by automating the assessment process. However, while many teachers agree that educational games increase motivation, learning, and retention, few are ready to fully trust them as an assessment tool. A likely reason behind this lack of trust is that educational games are distributed as black boxes, unmodifiable by educators and not providing enough insight about the gameplay. This chapter presents three systematic literature reviews looking into the integration of assessment, feedback, and learning analytics in educational games. It then proposes a framework and present a fully developed engine. The engine is used by both developers and educators. Designed to separate game and assessment, it allows teachers to modify the assessment after distribution and visualize gameplay data via a learning analytics dashboard.

Risk management is becoming increasingly more complex. Risk assessment, approached quantitatively, requires a factual database to define the likelihood of adverse health effects of workplace-related injuries and exposures, and it attempts to balance scientific knowledge with concerns of staff, investigators and administration. Practical guidance should be provided for Romanian coal mining companies to make progress in risk assessment process. Guidance is given on how to effectively introduce quantitative risk assessment in mining industry, the main goal being to highlight that the most valuable resource remains experience gained by effectively performing the process. Analyzing how various parameters are described/used, the paper aims to establish the place and role of quantitative risk analysis mining. Possibilities of developing safety/reliability database in coal mining are investigated. The block diagram describing the conceptual structure of a database on failures, safety of equipment and workers in the mining industry was developed. Because mining relies heavily on complex technologies - permanent mining facilities and large mobile equipment and support services - often located in isolated and hostile environments, the implementation of quantitative risk analysis and the development of a realistic database could be considered as a resilience business strategy and conversion of available knowledge into management actions.
