This study aims to analyze how much change is experienced by vocational training participants in paving block construction materials on learning in attitudes, knowledge, general skills, and specific skills (outcomes). In addition, this analysis is also intended to determine how the effect of vocational training on paving block construction materials on the results of the changes obtained. The training was held on December 21-24, 2020, at the Faculty of Engineering, University of IBA Palembang. Forty participants attended the training. The data in this analysis were obtained through pre-test and post-test. These changes are described in 4 predicates using simple regression analysis: excellent, better, already good, and not good. The regression results showed that an average of 15.625% of the participants experienced an increase in results, an average of 76.25% of the participants obtained stable/stable results, and an average of 8.125%. Of the participants experienced a decrease in results. The analysis results found that training had an effect of 3.1% on participants' attitudes, 15.8% on participants' knowledge, 19.8% on general skills of participants, and 0.2% on specific skills of participants. The R-square value is not very influential because most of the participants are craftsmen who have experience making paving blocks. It takes a strategy of activities focused on goals and an activity strategy to improve the final result. Thus, the participants' primary objective is to become competent construction workers of infrastructure, road construction, and settlements construction infrastructure can be achieved.

Background: Before interventions are implemented, the potential treatment benefit must be determined.Objectives: The primary objective of this feasibility study was to assess if peers’ attitudes towards children who stutter (CWS) change one month after the administration of the Classroom Communication Resource (CCR). The secondary objectives of the study were to determine if differences in peer attitudes were related to gender and to previous exposure to a person who stutters.Method: The study used a cluster randomised control trial design. The study included 211 Grade 7 participants from schools in the Cape Town Metropole. The CCR intervention was administered to 97 participants in the experimental group, whilst 114 participants in the control group did not receive the intervention. The Stuttering Resource Outcome Measure(SROM) used as the outcome measure during pre- and post-test period. STATISTICA was used for in-depth data analysis.Results: An overall positive direction of change in scores was observed for the experimental group compared with the control group. However, the magnitude of change in the experimental group was not statistically significant (p = 0.2683). Male and female participants did not differ significantly in their scores on the SROM across pre-test and post-test periods. Participants who had exposure to individuals who stutter had significantly more positive scores on the SROM in the pre-test and post-test periods compared to those who had no direct exposure to stuttering.Conclusion: This result indicated the beginning of positive attitude change which may be attributed to the intervention. Further investigation is warranted.

CREDO RADON UA software provides an automated calculation of the strength of the pavement structures of non-rigid and rigid types, as well as the calculation of the strengthening of existing structures. In the article, one can see the main features and functionality of the CREDO RADON UA software, the main points in the calculations according to the new regulations. Information support of the design process includes necessary databases, informational and helping materials that make up the full support of the pavement design process. The concept of CREDO RADON UA 1.0 software is made on the use of elasticity theory methods in calculations of initial information models of pavements. Performing optimization calculations, the roadwear in CREDO RADON UA is designed in such a way that no unacceptable residual deformation occurs under the influence of short-term dynamic or static loading in the working layer of the earth bed and in the structural layers during the lifetime of the structure. The calculation algorithms were made in accordance with the current regulatory documents of Ukraine. CREDO RADON UA software allows user to create information bases on road construction materials and vehicles as part of the traffic flow for calculations. The presented system of automated modeling makes it easier for the customer to control the quality of design solutions, to reasonably assign designs to layers of reinforcement, to quickly make comparisons of calculations of different designs for the optimal use of allocated funds. Prospects for further improvement of the program should be the results of theoretical and experimental studies on filling the databases, which are used as information support for automated design of road structures.

Abstract Objectives Neonates who develop moderate to severe encephalopathy following perinatal asphyxia will benefit from therapeutic hypothermia. Current National Institute of Child Health and Human Development (NICHD) criteria for identifying encephalopathic neonates needing therapeutic hypothermia has high specificity. This results in correctly identifying neonates who have already developed moderate to severe encephalopathy but miss out many potential beneficiaries who progress to develop moderate to severe encephalopathy later. The need is therefore not just to diagnose encephalopathy, but to predict development of encephalopathy and extend the therapeutic benefit for all eligible neonates. The primary objective of the study was to develop and validate the statistical model for prediction of moderate to severe encephalopathy following perinatal asphyxia and compare with current NICHD criteria. Methods The study was designed as prospective observational study. It was carried out in a single center Level 3 perinatal unit in India. Neonates>35 weeks of gestation and requiring resuscitation at birth were included. Levels of resuscitation and blood gas lactate were used to determine the pre-test probability, Thompson score between 3 and 5 h of life was used to determine post-test probability of developing encephalopathy. Primary outcome measure: Validation of Prediction of Encephalopathy in Perinatal Asphyxia (PEPA) score by Holdout method. Results A total of 55 babies were included in the study. The PEPA score was validated by Holdout method where the fitted receiver-operating characteristic (ROC) area for the training and test sample were comparable (p=0.758). The sensitivity and specificity of various PEPA scores for prediction of encephalopathy ranged between 74 and 100% in contrast to NICHD criteria which was 42%. PEPA score of 30 had a best combination of sensitivity and specificity of 95 and 89% respectively. Conclusions PEPA score has a higher sensitivity than NICHD criteria for prediction of Encephalopathy in asphyxiated neonates.

AbstractInvestigation into the cause of road failure has been carried out along a 60 km long Sagamu –Papalanto highway southwestern Nigeria. Geochemical, mineralogical, geotechnical and geophysical analyses were conducted to evaluate the cause of failure along the study area. The results of the laboratory tests showed that the percentage amount of fines ranges from 12 to 61.3%, natural moisture content from 6.8 to 19.7%, liquid limit in the range of 25.1–52.2%, linear shrinkage between 3.96 to 12.71%, plastic limit ranges from 18.2–35%, plasticity index ranges from 5.2 to 24.6%, free swell in the range from 5.17–43.9%, maximum dry density ranges from 1.51–1.74 g /cm3, specific gravity ranges from 2.52–2.64 and CBR between 3 and 12%. The Cone Penetrometer Test (CPT) shows a resistance value of 20–138 kgf/cm2. The major clay mineral that is predominant in the studied soil is kaolinite. The major oxides present are SiO2, Al2O3, Fe2O3, K2O, Na2O, MgO and CaO. The result of the 2D Electrical Resistivity Imaging revealed a low resistivity values for profile 2 and 3 ranging from 100 Ωm – 300 Ωm, between a distance of 20 m – 240 m along the profile to a depth of 7.60 m and a low resistivity value ranging from 50 Ωm – 111Ωm, between a distance of 80 m − 120 m along the profile to a depth of 15 m. It was concluded that the low CBR, low MDD and the class of subsoils namely A-26, A-7, A-2-7 (clayey soils) which were identified are responsible for the cause of failure experienced in the study area. These makes the soils unsuitable as road construction materials and hence, there is need for stabilization during the reconstruction and rehabilitation of the road.

The Individual

Context Vehicle-strike has been identified as a key threatening process for koala (Phascolarctos cinereus) survival and persistence in Australia. Roads and traffic act as barriers to koala movement and can impact dispersal and metapopulation dynamics. Given the high cost of wildlife mitigation structures such as purpose-built fauna-specific underpasses or overpasses (eco-passages), road construction and management agencies are constantly seeking cost-effective strategies that facilitate safe passage for fauna across roads. Here we report on an array of detection methods trialled to verify use of retrofitted road infrastructure (existing water culverts or bridge underpasses) by individual koalas in fragmented urban landscapes in south-east Queensland. Aims The study examined whether the retrofitting of existing road structures at six sites facilitated safe passage for koalas across roads. Our primary objective was to record utilisation of retrofitted infrastructure at the level of the individual. Methods We used a combination of existing monitoring methods such as GPS/VHF collars, camera traps, sand plots, and RFID tags, along with a newly developed animal-borne wireless identification (WID) tag and datalogging system, specifically designed for this project, to realise the study aims. Key results We were able to verify 130 crossings by koalas involving a retrofitted structure or a road surface over a 30-month period by using correlated data from complementary methods. We noted that crossings were generally uncommon and mostly undertaken by only a subset of our tagged individuals at each site (21% overall). Conclusions An important element of this study was that crossing events could be accurately determined at the level of the individual. This allowed for detailed assessment of eco-passage usage, rather than the more usual approach of simply recording species’ presence. Implications This study underscores the value of identifying the constraints of each individual monitoring method in relation to site conditions. It also highlights the benefits of contingency planning to limit data loss (i.e. using more than one method to collect data). We suggest an approach that uses complementary monitoring methods has significant advantages for researchers, particularly with reference to improving understanding of whether eco-passages are meeting their prescribed conservation goals.

A prototype for an expert system in road construction material selection system, which is based on the outcomes of Friedman and multiple comparisons statistical methods was developed. The outcomes were acquired through questionnaires from selected pavement experts. The factors affecting pavement materials under each particular site condition were incorporated into the specific rules of the system. The system knowledge-base was extracted from the statistical testing outcomes and then rearranged and compiled prior to the development of the system. Visual Basic 6.0 was adopted as the programming tool for development of the system, while the knowledge-base of the separate system was kept in Microsoft Access 2000. The prototype expert system can be used to emulate part of the professional reasoning capabilities based on the knowledge of a pavement expert or a specialist to solve problems on materials selection. The system can help road designers to improve their professional ability to evaluate all available materials even before carrying out any laboratory tests.
