Authors: Setiawan Imam Eko , Zhang Zhengyang , Corder Glen , Matsubae Kazuyo
Published: June 2021

While the successful reclamation of coal post-mining land sites in Indonesia has been evaluated, no cost-benefit analysis has been carried out on the reclamation of mined land, and the impact of the reclamation work has not been determined. The results of this case study indicate that reclamation work is not an emission-free process, but that the benefits delivered from this work are considerable. It was found that the emissions involved at the coal mined reclamation in Indonesia were 25.4–26.6 t-CO2/ha, with topsoil management and land preparation contributing over 98% of the total emissions (9.5 t-CO2/ha and 16 t-CO2/ha, respectively). The ability of the trees on the reclaimed land to absorb CO2 emissions was calculated to be 26.4 t-CO2/ha, with the amount of oxygen produced calculated to be as much as 143 t-O2/ha of oxygen. The economic value of the ecosystem services delivered by reclamation was over USD 27,750/ha. This is higher than the USD 8642–9417/ha cost of establishing the reclamation work. Improvements to reclamation work could be designed mining and reclamation plans with attention paid to reducing fuel consumption, and therefore, reducing CO2 emissions. Furthermore, law enforcement and transparency, human resource development, and community participation are strongly required.
A Labeled GM-PHD Filter for Explicitly Tracking Multiple Targets
Authors: Gao Yiyue , Jiang Defu , Zhang Chao , Guo Su
Published: June 2021

In this study, an explicit track continuity algorithm is proposed for multitarget tracking (MTT) based on the Gaussian mixture (GM) implementation of the probability hypothesis density (PHD) filter. Trajectory maintenance and multitarget state extraction in the GM-PHD filter have not been effectively integrated to date. To address this problem, we propose an improved GM-PHD filter. In this approach, the Gaussian components are classified and labeled, and multitarget state extraction is converted into multiple single-state extractions. This provides the identity label of the individual target and can shield against the negative effects of clutter in the prior density region on the estimates, thus realizing the integration of trajectory maintenance with state extraction in the GM-PHD filter. As no additional associated procedures are required, the overall real-time performance of the proposed filter is similar to or slightly lower than that of the basic GM-PHD filter. The results of numerical experiments demonstrate that the proposed approach can achieve explicit track continuity.

Measurement of pH in aqueous-organic mixtures with different compositions is of high importance in science and technology, but it is, at the same time, challenging both from a conceptual and practical standpoint. A big part of the difficulty comes from the fundamental incomparability of conventional pH values between solvents (spH, solvent-specific scales). The recent introduction of the unified pH (pHabs) concept opens up the possibility of measuring pH, expressed as pHabsH2O, in a way that is comparable between solvent, and, thereby, removing the conceptual problem. However, practical issues remain. This work presents the experience of the authors with measuring pHabsH2O values in mixtures of methanol, ethanol, and acetonitrile, with water, but without the presence of buffers or other additives. The aim was to assigned pHabsH2O values to solvent–water mixtures using differential potentiometry and the ‘pHabs-ladder’ method. Measurements were made of the potential difference between glass electrodes immersed in different solutions, separated by an ionic liquid salt bridge. Data were acquired for a series of solutions of varying solvent content. This work includes experiences related to: a selection of commercial electrodes, purity of starting material, and comparability between laboratories. Ranges of pHabsH2O values for selected compositions of solvent–water mixtures are presented.
ReS2tAC—UAV-Borne Real-Time SGM Stereo Optimized for Embedded ARM and CUDA Devices

Published: June 2021

With the emergence of low-cost robotic systems, such as unmanned aerial vehicle, the importance of embedded high-performance image processing has increased. For a long time, FPGAs were the only processing hardware that were capable of high-performance computing, while at the same time preserving a low power consumption, essential for embedded systems. However, the recently increasing availability of embedded GPU-based systems, such as the NVIDIA Jetson series, comprised of an ARM CPU and a NVIDIA Tegra GPU, allows for massively parallel embedded computing on graphics hardware. With this in mind, we propose an approach for real-time embedded stereo processing on ARM and CUDA-enabled devices, which is based on the popular and widely used Semi-Global Matching algorithm. In this, we propose an optimization of the algorithm for embedded CUDA GPUs, by using massively parallel computing, as well as using the NEON intrinsics to optimize the algorithm for vectorized SIMD processing on embedded ARM CPUs. We have evaluated our approach with different configurations on two public stereo benchmark datasets to demonstrate that they can reach an error rate as low as 3.3%. Furthermore, our experiments show that the fastest configuration of our approach reaches up to 46 FPS on VGA image resolution. Finally, in a use-case specific qualitative evaluation, we have evaluated the power consumption of our approach and deployed it on the DJI Manifold 2-G attached to a DJI Matrix 210v2 RTK unmanned aerial vehicle (UAV), demonstrating its suitability for real-time stereo processing onboard a UAV.
Retrofitting Agricultural Self-Propelled Machines with Roll-Over and Tip-Over Protective Structures
Authors: Vita Leonardo , Gattamelata Davide , Pessina Domenico
Published: June 2021

In the agricultural sector, the loss of stability related to the use of self-propelled agricultural machinery (SPAM) has caused and continues to cause accidents, often with fatal outcomes. The probability of occurrence of this risk can be reduced by acting on various aspects, but above all the presence of a protective structure is necessary. Depending on the machine, the protective structure can be a roll-over protective structure (ROPS), or a tip-over protective structure (TOPS). Hence, to reduce this gap, a reverse engineering approach and virtual engineering methods were applied starting from the analysis of harmonized standards actually in force, with the goal of providing both a reference procedure to be used in the risk assessment analysis of SPAM’s protective structures and technical information to manufacture and install protective structure on old agricultural machinery. Two representative case studies were used to validate the procedure by means of finite element method (FEM) analyses and computer aided design (CAD) prototyping. Results show that the proposed approach can represent a useful indication for the safety update of this type of machinery.
Integrated IEW-TOPSIS and Fire Dynamics Simulation for Agent-Based Evacuation Modeling in Industrial Safety
Authors: Chanthakhot Wattana , Ransikarbum Kasin
Published: June 2021

Emergency events in the industrial sector have been increasingly reported during the past decade. However, studies that focus on emergency evacuation to improve industrial safety are still scarce. Existing evacuation-related studies also lack a perspective of fire assembly point’s analysis. In this research, location of assembly points is analyzed using the multi-criteria decision analysis (MCDA) technique based on the integrated information entropy weight (IEW) and techniques for order preference by similarity to ideal solution (TOPSIS) to support the fire evacuation plan. Next, we propose a novel simulation model that integrates fire dynamics simulation coupled with agent-based evacuation simulation to evaluate the impact of smoke and visibility from fire on evacuee behavior. Factors related to agent and building characteristics are examined for fire perception of evacuees, evacuees with physical disabilities, escape door width, fire location, and occupancy density. Then, the proposed model is applied to a case study of a home appliance factory in Chachoengsao, Thailand. Finally, results for the total evacuation time and the number of remaining occupants are statistically examined to suggest proper evacuation planning.
Model for the Evaluation of Teaching Competences in Teaching–Learning Situations
Authors: De Pro Chereguini Carlos , Ponce Gea Ana Isabel
Published: June 2021

Social changes have brought educational challenges at all levels of education. One of the most important elements has been adopting the development of competences as a main goal. As regards teacher training, competences have been included in university degrees responding to a traditional concern related to teacher training: the necessary relationship between theory and educational practice. The objective of this work, in the Spanish context, is to define a model for the evaluation of didactic-disciplinary competences (frequently taught in university classrooms, in a theoretical way) within the framework of the school practicums of the degree in early childhood education (the unique practical context where a real application of competences may be assessed before professional performance). For this purpose, we analyzed the legislation (the specific didactic-disciplinary competences of the ECI/3854/2007 Order) and the school practicum plans of Spanish universities, in order to provide a useful tool to know how students apply theoretical learning in their classroom practices. The resulting model, focused on the learning of natural sciences, social sciences and mathematics, enables understanding the level of development of the didactic-disciplinary competences and can be considered as a conceptual framework to design instruments for different contexts.
COVID-ized Ethnography: Challenges and Opportunities for Young Environmental Activists and Researchers
Authors: Arya Dena , Henn Matt
Published: June 2021

This article offers a critical and reflective examination of the impact of the enforced 2020/21 COVID-19 lockdown on ethnographic fieldwork conducted with UK-based young environmental activists. A matrix of researcher and activist challenges and opportunities has been co-created with young environmental activists using an emergent research design, incorporating a phased and intensive iterative process using online ethnography and online qualitative interviews. The article focuses on reflections emerging from the process of co-designing and then use of this matrix in practice. It offers an evidence base which others researching hard-to-reach youth populations may themselves deploy when negotiating face-to-face fieldwork approval at their own academic institutions. The pandemic and its associated control regimes, such as lockdown and social distancing measures, will have lasting effects for both activism and researchers. The methodological reflections we offer in this article have the potential to contribute to the learning of social science researchers with respect to how best to respond when carrying out online fieldwork in such contexts—particularly, but not only, with young activists.
“Is It Overtraining or Just Work Ethic?”: Coaches’ Perceptions of Overtraining in High-Performance Strength Sports
Authors: Bell Lee , Ruddock Alan , Maden-Wilkinson Tom , Hembrough Dave , Rogerson David
Published: June 2021

Optimal physical performance is achieved through the careful manipulation of training and recovery. Short-term increases in training demand can induce functional overreaching (FOR) that can lead to improved physical capabilities, whereas nonfunctional overreaching (NFOR) or the overtraining syndrome (OTS) occur when high training-demand is applied for extensive periods with limited recovery. To date, little is known about the OTS in strength sports, particularly from the perspective of the strength sport coach. Fourteen high-performance strength sport coaches from a range of strength sports (weightlifting; n = 5, powerlifting; n = 4, sprinting; n = 2, throws; n = 2, jumps; n = 1) participated in semistructured interviews (mean duration 57; SD = 10 min) to discuss their experiences of the OTS. Reflexive thematic analysis resulted in the identification of four higher order themes: definitions, symptoms, recovery and experiences and observations. Additional subthemes were created to facilitate organisation and presentation of data, and to aid both cohesiveness of reporting and publicising of results. Participants provided varied and sometimes dichotomous perceptions of the OTS and proposed a multifactorial profile of diagnostic symptoms. Prevalence of OTS within strength sports was considered low, with the majority of participants not observing or experiencing long-term reductions in performance with their athletes.
Financing Climate Change Adaptation: International Initiatives
Authors: Timilsina Govinda R.
Published: June 2021

Climate change adaptation is one of the main strategies to address global climate change. The least developed countries and the small island states that lack financial resources to adapt to climate change are the most vulnerable nations to climate change. Although it would be more economical to adapt to climate change compared to the anticipated damage of not doing so, the demand for capital is estimated to range to hundreds of billions. The crucial question is how to manage investments to adapt to climate change globally. This study provides an overview of existing international provisions on climate finance for adaptation. It includes provisions through international financial institutions, United Nations agencies, bilateral and multilateral channels, and the private sector. It also explores how private sector finance can be further attracted to invest in climate change adaptation.
Ecophysiological Aspects and sxt Genes Expression Underlying Induced Chemical Defense in STX-Producing Raphidiopsis raciborskii (Cyanobacteria) against the Zooplankter Daphnia gessneri

Published: June 2021

Cyanobacteria stand out among phytoplankton when they form massive blooms and produce toxins. Because cyanotoxin genes date to the origin of metazoans, the hypothesis that cyanotoxins function as a defense against herbivory is still debated. Although their primary cellular function might vary, these metabolites could have evolved as an anti-predator response. Here we evaluated the physiological and molecular responses of a saxitoxin-producing Raphidiopsis raciborskii to infochemicals released by the grazer Daphnia gessneri. Induced chemical defenses were evidenced in R. raciborskii as a significant increase in the transcription level of sxt genes, followed by an increase in saxitoxin content when exposed to predator cues. Moreover, cyanobacterial growth decreased, and no significant effects on photosynthesis or morphology were observed. Overall, the induced defense response was accompanied by a trade-off between toxin production and growth. These results shed light on the mechanisms underlying zooplankton–cyanobacteria interactions in aquatic food webs. The widespread occurrence of the cyanobacterium R. raciborskii in freshwater bodies has been attributed to its phenotypic plasticity. Assessing the potential of this species to thrive over interaction filters such as zooplankton grazing pressure can enhance our understanding of its adaptive success.
“You Can’t Manage What You Can’t Measure”: Perspectives of Transplant Recipients on Two Lifestyle Interventions for Weight Management
Authors: Anderson Suzanne , Brown Catherine , Venneri Katherine , Horne Justine R. , Matthews June I. , Madill Janet E.
Published: June 2021

Previous research suggests that effective lifestyle interventions for solid organ transplant (SOT) recipients must be tailored to address the unique life circumstances of this population. As few studies have investigated this design consideration, this study aimed to explore the perspectives and experiences of SOT recipients after completing a Group Lifestyle Balance™ [GLB]-based intervention incorporating either (a) standard population-based nutrition guidance or (b) nutrigenomics-based nutrition guidance. All active participants in the Nutrigenomics, Overweight/Obesity, and Weight Management-Transplant (NOW-Tx) pilot study were invited to participate. Data were collected through focus groups and individual interviews. Ninety-five percent (n = 18) of the NOW-Tx pilot study participants enrolled in the current study: 15 participated in 3 focus groups; 3 were interviewed individually. Three themes were common to both intervention groups: (1) the post-transplant experience; (2) beneficial program components; (3) suggestions for improvement. A unique theme was identified for the nutrigenomics-based intervention, comprising the sub-themes of intervention-specific advantages, challenges, and problem-solving. The readily available and adaptable GLB curriculum demonstrated both feasibility and acceptability and was aligned with participants’ needs and existing health self-management skills. The addition of nutrigenomics-based guidance to the GLB curriculum may enhance motivation for behaviour change in this patient population.
Objective and Subjective Evaluation of Saccadic Eye Movements in Healthy Children and Children with Neurodevelopmental Disorders: A Pilot Study
Authors: Bilbao Carmen , Piñero David P.
Published: June 2021

The objective of this study was to characterize saccades in children with neurodevelopmental disorders (NDDG, 17 children, age: 7–12 years) and compare them with a control group (CG, 15 children, age: 7–12 years), comparing the outcomes obtained with a subjective score system (Northeastern State University College of Optometry’s Oculomotor test, NSUCO) with the objective analysis obtained through a commercially available Eye Tracker (Tobii Eye X, Tobii, Stockholm, Sweden) and a specialized software analysis (Thomson Software Solutions, Welham Green, UK). Children from the NDDG obtained significantly lower NSUCO scores (p < 0.001) compared with CG. Concerning eye tracking analyses, we found a significantly higher number of hypometric saccades in NDGG (p ≤ 0.044). Likewise, we found a significantly higher percentage of regressions in the NDDG for a time interval of presentation of stimuli of 1 s (p = 0.012). Significant correlations were found between different NSUCO scores and percentage of regressions, number of saccades completed and number of hypometric saccades. The presence of hypometric saccades and regressions seems to be a differential characteristic sign of children with neurodevelopmental disorders that can be detected using an objective eye tracking analysis, but also using the subjective test NSUCO that can be easily implemented in all clinical settings.

Recently, a signifi cant number of livestock of specialized beef breeds is imported from abroad particularly from Australia. So the study of the adaptive ability and eff ectiveness of the use of Australian cattle of Hereford breed in the Amur region is relevant. The purpose of the work was to study the growth, development and reproductive capacity of Hereford cattle in the Amur region. Experimental studies have been carried out in the collective farm “Tomichevsky” in the Belogorsky district in the Amur region for four years. The reproductive ability of imported Hereford cows of Australian selection, as well as indicators of calving easy, live weight and height in the rump have been examined in the article. The assessment of similar indicators of progeny obtained from imported cows-dams and dams of local selection have been given. It has been found that the cows of the Australian breeding had a large live weight and were taller than the cows of Hereford breed the same age as the cows of Amur breeding. Fewer off spring were obtained from imported cows, a high percentage of dead calves were born, long open day’s period and calving interval, and a low coeffi cient of reproductive ability have been revealed. When analyzing the results of the study of the adaptive ability of Hereford cows obtained from imported Australian Hereford cows and Hereford cows of the Amur breeding, it has been found that all calving were successful in the cows, and no cases of dead calves were born. Indicators of reproductive ability were within the normal range, but were more optimal in the progeny of Australian breeding. The results obtained on base of researches we can conclude that the progeny of Australian Herefords have higher adaptive abilities in comparison with similar indicators of their mothers.

In order to ensure the growth of beef production, it is necessary to rationally use all available reserves and, fi rst of all, the allocation of intra-breed types and lines that ensure the improvement of herds and breeds of animals with high genetic potential under specifi c natural conditions. Therefore when breeding cattle of dual purposes breeds important role should be attached to the selection of animals of diff erent lines, body types, related groups that provide high fattening, and beef indicators with good adaptive traits. In relation with the above, it has been considered relevant to study the formation of beef productivity of steers of diff erent exterior and constitutional intra-breed types of Simmental breed with the determination of the energy and biological value of products under intensive rearing. As well as the infl uence of feeding conditions and maintenance of young animals of Simmental breed, taking into account the exterior and constitutional type, on the formation of live weight in the postnatal period, with a comparative assessment of the growth intensity depending on the body type. As a result of the research, the association between the live weight and the weight of the most active internal organs: heart, lungs, kidneys, which characterize the level and nature of metabolic processes that have a positive eff ect on the formation of beef productivity of experimental Simmental steers of domestic selection depending on the exterior and constitutional types. It has been found that to increase the production of high-quality beef, it is advisable to intensively rear Simmental steers of medium and compact types up to 18 months of age with a live weight of 460,2–517,8 kg, a carcass weight of 252,3–282,4 kg, a slaughter yield of 58,1–59,4 % and expenditures of feed of 3,7–4,0 thousand tons of EFU per 1 head.

The lack of a comprehensive quality evaluation often leads to the fact that meat products do not correspond to their name in composition or are of poor quality. The purpose of our researches shows how the comprehensive evaluation of the quality parameters of dry sausages is important to identify the composition of their name, the recipe and regulatory requirements. Dry sausages of diff erent brands of “Braunschweig” and “Jewish” varieties have been studied. Comprehensive researches of quality parameters have been carried out by organoleptic, physic and chemical methods, which determined the pH, mass fraction of moisture, content of sodium chloride and nitrite; microbiological methods, including the determination of Escherichia coli group bacteria, E. coli, S. aureus and sulfi tereducing clostridium; as well as microstructure methods and PCR, which determined the quality of raw meat raw materials and its possible falsifi cations. It has been found as a result that none of the studied samples fully meets the regulatory requirements. In particular, one of the samples was unsafe due to the presence of Escherichia coli group bacteria and E. coli. In some samples additives based on animal proteins were found not indicated on the label, and with the help of PCR some samples have been found to have a mismatch in the composition of the original meat raw materials GOST. At the same time, according to the results of analysis by separate methods, many samples fully met the requirements of the standards. Thus, the results obtained confi rm the need for comprehensive researches of food products, since only such the evaluation can ensure their safety and quality.

Published: June 2021

Primary changes in the physiological status of animals can be traced in the deviation from the norm of indicators of a number of substances in biological fl uids, since biochemical indicators are a kind of indicator of processes occurring in the body. Having knowledge of hematological changes in the body of cattle, managers and specialists of livestock farms can manage the productivity and health of highly productive animals. The purpose of the research was to determine and analyze the biochemical parameters of the blood of cows in the dry period and at the increasing the milk yield when wet crushed corn grain was introduced into their ration. The research has been carried out on cows of Black-and-White breed in LLC “Agrofi rma “Urozhai” in the Zonal district in the Altai Territory. During the research the prevalence of productivity indicators of cows of the experimental group over analogues from the control group was proved. Thus average daily milk yield for the accounting period (60 days) it was 30,9 kg, which was 5,2 kg more than the control herdmates (P > 0,95). The total productivity of one head was 1541,57 kg of milk in the control group and 1854,69 kg in the experimental group, which was 313,12 kg more (P > 0,95). It has been found that most of the studied biochemical parameters corresponded to the physiological norm. The exception was the increased content of total protein in the blood of lactating cows of the experimental group 5 g/l above the upper limit of the norm (P > 0,999). A low albumin content in the blood of animals of the experimental group has been noted, and this indicator was signifi cantly lower than that in the control group by 3,45 g/l (P > 0,99). An excess of the physiological norm of globulin in the blood of animals of both groups has been found, the indicators of the experimental group signifi cantly exceeded the control group by 9,5 g/l (P > 0,99). There was a low level of chlorides after the increasing the milk yield 88,1 mmol/l in the control group and 89,2 mmol/l in the experimental group, then excess of manganese after the increasing the milk yield was 4,50 mmol/l in the control group and 8,14 mmol/l in the experimental group, which could be associated with the increased content of this element in feed and soil.

Published: June 2021

This research is devoted to the variability of linear and weight growth of Sander lucioperca (Stizostedion lucioperca) in the Novosibirsk water-storage basin. The presented work is part of a comprehensive research of Sander lucioperca phenotypic pool of the Novosibirsk water-storage basin. 43 individuals have been selected for the analysis aged 3,0–4,5 years in the period October-November 2019. Measurements of Sander lucioperca have been carried out according to the “Manual for the study of fi sh”, the fi sh has been weighed on a technical scale VLKT-500 with an accuracy of 1 g. The fi rst time the linear and some aspects of the weight growth of Sander lucioperca in the Novosibirsk water-storage basin have been described in the paper, since the growth directly depends on the development and is one of its components. The biological characteristics and features of Sander lucioperca have been analyzed. For the development of the population of Sander lucioperca as well as other fi sh species one of the main biotic factors is the feed supply. The availability of feed for hydrobionts is determined by the quantity, quality and availability of feed in the reservoir, since the feed supply has a signifi cant impact on the biological parameters of fi sh. The ecological situation of the Novosibirsk water-storage basin has been studied. The obtained data on Sander lucioperca measurements can be used as average population values. Increasing the parameters of the assessment of living organisms makes it possible to more accurately assess the conformation of animals. A high level of correlation (r=0,878) between the linear and weight growth of Sander lucioperca has been established, and a regression equation describing the change in length as a function of live weight (y = 9,5853 x + 39,1164) has been calculated. There is a tendency to decrease the number of Sander lucioperca in the Novosibirsk water-storage basin.

Recently, many countries have tightened requirements for the quality of compound feed and its individual components including vitamins. However, the vitamins of grain and protein feed may not be available for assimilation by animals that have been destroyed or lost activity during storage. The purpose of this work was to provide scientific and practical substantiation of use in diets of sows biotin and folic acid to enhance their reproductive ability and improve the physiological state ensure, through the use of brooders, the best micro-climate in the area is received from off spring to enhance growth and the survival of piglets. The experimental part of the work has been performed at the pig breeding complex APC “Ovsyanka”, MAUE “Ovsyanka named after I. I. Melnik” in the Goretsky district in the Mogilev region in the Republic of Belarus. For the first time in the Republic of Belarus under the industrial technology of animal husbandry the use of biotin and folic acid additives in the diets of sows has been scientifically justified. The optimal doses of biotin and folic acid additives in the compound feed have been developed to increase reproductive ability and improve the physiological state of sows. The possibility of using cylindrical brooders with a truncated cone in combination with various sources of local heating in the piglets’ recreation area has been experimentally established. The economic feasibility of using biotin and folic acid additives in the diets of sows and brooders in the recreation area of their off spring has been proved.

Vitamins take signifi cant place among the factors of complete feeding of pigs, their lack in the diet causes metabolic disorders, reduced productivity. The purpose of this work was to provide a practical justifi cation of diets for rearing and fattening young pigs based on concentrate mixtures enriched with mineral and vitamin premix with an increased content of group B vitamins. The selection of animals in groups has been carried out taking into account live weight, origin and health status, per 10 animals in each group. Animals in the control group have been fed a basic diet and premix P-554-89 in the amount of 1,0 % of the daily weight of the grain mixture, to piglets of the experimental group to the main diet with the mineral and vitamin premix of 1,0 % of the weight of the grain mixture have been added. The eff ect of the mineral-vitamin premix with increased level of group B vitamins on the digestibility of nutrients and energy metabolism has been studied. The eff ectiveness of rearing and fattening young pigs on diets with a high content of group B vitamins (B1 , B2 , B3 , B5 , B6 , B12) has been proven. Inclusion of a premix with increased content of group B vitamins compared to the recipe P-55-4-89 in the amount of 1,0 % of the weight of the grain mixture increases the productivity of young animals on fattening. At 8 months of age piglets reached a live weight of 109,1 kg, which was 8,8 kg or 8,77 % more than in control animals. The use of this premix in the amount of 1,0 % of the weight of the grain mixture reduces the prime-cost by 7,01 %, and the profi tability of rearing fattening young animals increases by 9,20 %.

Health information technology (HIT) provides many benefits, but also facilitates certain types of errors, such as wrong-patient errors in which one patient is mistaken for another. These errors can have serious patient safety consequences and there has been significant effort to mitigate the risk of these errors through national patient safety goals, in-depth research, and the development of safety toolkits. Nonetheless, these errors persist. We analyzed 1,189 patient safety event reports using a safety science and resilience engineering approach, which focuses on identifying processes to discover errors before they reach the patient so these processes can be expanded. We analyzed the general care processes in which wrong-patient errors occurred, the clinical process step during which the error occurred and was discovered, and whether the error reached the patient. For those errors that reached the patient, we analyzed the impact on the patient, and for those that did not reach the patient, we analyzed how the error was caught. Our results demonstrate that errors occurred across multiple general care process areas, with 24.4% of wrong-patient error events reaching the patient. Analysis of clinical process steps indicated that most errors occurred during ordering/prescribing (n=498; 41.9%) and most errors were discovered during review of information (n=286; 24.1%). Patients were primarily impacted by inappropriate medication administration (n=110; 37.9%) and the wrong test or procedure being performed (n=65; 22.4%). When errors were caught before reaching the patient, this was primarily because of nurses, technicians, or other healthcare staff (n=303; 60.5%). The differences between the general care processes can inform wrong-patient error risk mitigation strategies. Based on these analyses and the broader literature, this study offers recommendations for addressing wrong-patient errors using safety science and resilience engineering, and it provides a unique lens for evaluating HIT wrong-patient errors.

Cerium oxide nanoparticle (CeO2NPs) has wide applications in pharmaceutical, biomedical and chemical industries. Albeit of their uses, bioavailability followed by toxicity of CeO2NPs in fresh water fishes, are yet to be understood in detail. In this evaluation, we have synthesized, characterized and assessed the biological effects (hematology, ionoregulatory, oxidative stress, histological and glutamate indices) of CeO2NPs at different doses (2.5mg/L and 25mg/L based on 1/10th LC50) on freshwater carps Cirrhinus mrigala, for short term exposure of 96 h. Impact of CeO2NPs at low concentration (2.5mg/L) confirmed a significant decrease in hematological parameters and also affecting serum Na+, Cl-, K+ levels along with gill Na+/K+-ATPase activity. The indicated variations oxidative stress enzymes superoxide dismutase, Catalase, glutathione peroxidase with relative elevation in lipid peroxidation (LPO) (22.47±0.198) compared to control groups. CeO2NPs at high concentration (25mg/L) revealed the alterations in neurotransmitter glutamate levels compared to control groups. Rise in glucose and decrease in plasma protein levels in response to both the concentrations was noted. Microscopic observations confirmed the tissue damages and alterations in gill architecture. By integrating all results obtained by short term exposure of juvenile carps to CeO2NPs at different doses, we reported nanoparticles have considerable deleterious effects on physiological and morphological condition of fishes.

Penelitian ini dilakukan untuk menganalisis konsep muhkam dan mutasyabih serta nilai-nilai pendidikan yang terdapat dalam kedua term tersebut. Istilah muhkam dan mutasyabih jarang difahami oleh guru selaku tenaga pengajar dalam prosesm pembelajaran. Kedua term ini hanya difahami oleh mereka yang khusus mengkaji dan menganaslis Al-Qur’an secara mendalam. Karena pada dasarnya Al-Qur’an adalah rujukan utama dalam pendidikan Islam, maka seyogyanya guru harus mengerti bagaimana konsep muhkam dan mutasyabih serta memahami nilai-nilai yang bisa dipetik dari adanya pengklasifikasian ayat-ayat Al-Qur’an berdasarkan kedua term tersebut. Penelitan yang dilakukan dalam tulisan ini adalah pendekatan kepustakaan. Hasil dari analisis ini mengungkapkan bahwa terdapat perbedaan pendapat para ulama dalam menganalsis ayat-ayat suci Al-Qur’an, terutama pada ayat-ayat yang masuk dalam kategori mutasyabihat. Dari perbedaan pendapat tersebut nilai-nilai pendidikan yang dapat dipetik dari adanya muhkam dan mutasyabih adalah nilai toleransi, nilai mujahadah, nilai tauhid, dan nilai pendidikan kontekstual.
