Authors: Τσαλίκη Χριστίνα , Καριώτογλου Πέτρος 
Published: December 2023

Στην εργασία μελετώνται στοιχεία διδασκαλίας Φυσικών Επιστημών (ΦΕ) διερευνητικού τύπου όπως αυτά αναπτύχθηκαν σε ένα πρόγραμμα Επαγγελματικής Ανάπτυξης (ΕΑ) εκπαιδευτικών. Το πρόγραμμα διήρκησε ένα χρόνο και σε αυτό συμμετείχαν τέσσερις εκπαιδευτικοί Πρωτοβάθμιας και Δευτεροβάθμιας εκπαίδευσης. Ειδικότερα, οι πρακτικές τους μελετήθηκαν με μη συμμετοχική παρατήρηση τόσο κατά τη διάρκεια του προγράμματος όσο και ένα χρόνο μετά από τη λήξη του. Τα αποτελέσματα δείχνουν πως οι εκπαιδευτικοί ενσωμάτωσαν στοιχεία καθοδηγούμενης διερεύνησης στις πρακτικές τους, τα οποία παρέμεναν και μετά την ολοκλήρωση του προγράμματος. Παράλληλα, εμφανείς ήταν οι δυσκολίες που αντιμετωπίστηκαν στην υιοθέτηση περισσότερο ανοιχτών διερευνητικών πρακτικών.

Learning-Augmented Mechanism Design: Leveraging Predictions for Facility Location
Authors: Agrawal Priyank , Balkanski Eric , Gkatzelis Vasilis , Ou Tingting , Tan Xizhi 
Published: December 2023

In this work, we introduce an alternative model for the design and analysis of strategyproof mechanisms that is motivated by the recent surge of work in “learning-augmented algorithms.” Aiming to complement the traditional worst-case analysis approach in computer science, this line of work has focused on the design and analysis of algorithms that are enhanced with machine-learned predictions. The algorithms can use the predictions as a guide to inform their decisions, aiming to achieve much stronger performance guarantees when these predictions are accurate (consistency), while also maintaining near-optimal worst-case guarantees, even if these predictions are inaccurate (robustness). We initiate the design and analysis of strategyproof mechanisms that are augmented with predictions regarding the private information of the participating agents. To exhibit the important benefits of this approach, we revisit the canonical problem of facility location with strategic agents in the two-dimensional Euclidean space. We study both the egalitarian and utilitarian social cost functions, and we propose new strategyproof mechanisms that leverage predictions to guarantee an optimal trade-off between consistency and robustness. Furthermore, we also prove parameterized approximation results as a function of the prediction error, showing that our mechanisms perform well, even when the predictions are not fully accurate.

Metric information in cognitive maps: Euclidean embedding of non-Euclidean environments
Authors: Baumann Tristan , Mallot Hanspeter A. 
Published: December 2023

The structure of the internal representation of surrounding space, the so-calledcognitive map, has long been debated. A Euclidean metric map is the most straight-forward hypothesis, but human navigation has been shown to systematically deviate from the Euclidean ground truth. Vector navigation based on non-metric models can better explain the observed behavior, but also discards useful geometric properties such as fast shortcut estimation and cue integration.Here, we propose another alternative, a Euclidean metric map that is systematically distorted to account for the observed behavior. The map is found by embedding the non-metric model, a labeled graph, into 2D Euclidean coordinates. We compared these two models using data from a human behavioral study where participants had to learn and navigate a non-Euclidean maze (i.e., with wormholes) and perform direct shortcuts between different locations. Even though the Euclidean embedding cannot correctly represent the non-Euclidean environment, both models predicted the data equally well. We argue that the embedding naturally arises from integrating the local position information into a metric framework, which makes the model more powerful and robust than the non-metric alternative. It may therefore be a better model for the human cognitive map.

Published: December 2023

Background
Blood pressure, grip strength and lung function are frequently assessed in longitudinal population studies, but the measurement devices used differ between studies and within studies over time. We aimed to compare measurements ascertained from different commonly used devices.

Methods
We used a randomised cross-over study. Participants were 118 men and women aged 45–74 years whose blood pressure, grip strength and lung function were assessed using two sphygmomanometers (Omron 705-CP and Omron HEM-907), four handheld dynamometers (Jamar Hydraulic, Jamar Plus+ Digital, Nottingham Electronic and Smedley) and two spirometers (Micro Medical Plus turbine and ndd Easy on-PC ultrasonic flow-sensor) with multiple measurements taken on each device. Mean differences between pairs of devices were estimated along with limits of agreement from Bland-Altman plots. Sensitivity analyses were carried out using alternative exclusion criteria and summary measures, and using multilevel models to estimate mean differences.

Results
The mean difference between sphygmomanometers was 3.9mmHg for systolic blood pressure (95% Confidence Interval (CI):2.5,5.2) and 1.4mmHg for diastolic blood pressure (95% CI:0.3,2.4), with the Omron HEM-907 measuring higher. For maximum grip strength, the mean difference when either one of the electronic dynamometers was compared with either the hydraulic or spring-gauge device was 4-5kg, with the electronic devices measuring higher. The differences were small when comparing the two electronic devices (difference = 0.3kg, 95% CI:-0.9,1.4), and when comparing the hydraulic and spring-gauge devices (difference = 0.2kg, 95% CI:-0.8,1.3). In all cases limits of agreement were wide. The mean difference in FEV1 between spirometers was close to zero (95% CI:-0.03,0.03), limits of agreement were reasonably narrow, but a difference of 0.47l was observed for FVC (95% CI:0.53,0.42), with the ndd Easy on-PC measuring higher.

Conclusion
Our study highlights potentially important differences in measurement of key functions when different devices are used. These differences need to be considered when interpreting results from modelling intra-individual changes in function and when carrying out cross-study comparisons, and sensitivity analyses using correction factors may be helpful.
Early childhood trajectories of domain-specific developmental delay and gestational age at birth: An analysis of the All Our Families cohort
Authors: Stephenson Nikki L. , Tough Suzanne , Williamson Tyler , McDonald Sheila , McMorrris Carly , Metcalfe Amy 
Published: December 2023

Objective
To describe developmental domain-specific trajectories from ages 1 through 5 years and to estimate the association of trajectory group membership with gestational age for children born between ≥34 and <41 weeks gestation.

Methods
Using data from the All Our Families cohort, trajectories of the domain-specific Ages & Stages Questionnaire scores were identified and described using group-based trajectory modeling for children born ≥34 and <41 weeks of gestation (n = 2664). The trajectory groups association with gestational age was estimated using multinomial logistic regression.

Results
Across the five domains, 4–5 trajectory groups were identified, and most children experienced changing levels of risk for delay over time. Decreasing gestational age increases the Relative risk of delays in fine motor (emerging high risk: 1.46, 95% CI: 1.19–1.80; resolving moderate risk: 1.11, 95% CI: 1.03–1.21) and gross motor (resolving high risk: 1.21, 95% CI: 1.04–1.42; and consistent high risk: 1.64, 95% CI: 1.20–2.24) and problem solving (consistent high risk: 1.58 (1.09–2.28) trajectory groups compared to the consistent low risk trajectory groups.

Conclusion
This study highlights the importance of longitudinal analysis in understanding developmental processes; most children experienced changing levels of risk of domain-specific delay over time instead of having a consistent low risk pattern. Gestational age had differential effects on the individual developmental domains after adjustment for social, demographic and health factors, indicating a potential role of these factors on trajectory group membership.

Background
The incidence of falling has always been high among the elderly, and it was easy to cause injuries to the elderly and seriously affect their quality of life. There were many studies have been conducted on risk factors affecting the fall of the elderly, but the results widely, retirement institutions as a gathering place for the elderly, there was currently no comprehensive analysis of the factors related to elderly falls in pension institutions. This study aimed to explore the influencing factors of falls among older adults in Chinese nursing homes.

Methods
Chinese and English databases were searched for literature published from database inception to 5 April 2023 on the influencing factors of falls among older adults in Chinese nursing homes. Two reviewers independently screened articles, extracted data, and assessed the quality of the included studies. Meta-analysis was performed using RevMan 5.4 software.

Results
Eleven studies involving 3503 participants were included in the meta-analysis. The pooled estimate of falls among older adults in Chinese nursing homes was 32% [95% confidence interval (95%CI) (24.0%, 39.0%)]. The main influencing factors for falls among older adults in Chinese nursing homes were age (Odds Ratio (OR) = 1.53), gender (OR = 5.50), visual impairment (OR = 2.30), sedative-hypnotics (OR = 2.36), fear of falling (OR = 2.95), hypertension (OR = 3.72), static balance (OR = 2.02), three or more chronic diseases (OR = 5.63), cognitive status (OR = 2.64), walking aid use (OR = 1.98), fall-related chronic diseases (OR = 2.48), self-awareness of abilities (OR = 2.43), and frequent reminders for fall prevention (OR = 0.10).

Conclusion
Falls among older adults in Chinese nursing homes were common, and there were many influencing factors. Timely screening and intervention should be implemented to reduce the adverse consequences of falls on older adults.

Authors: Faruqi Muhammad Alfian , Mohammed Bashar S , Anwar Abdullah , Dharmawansyah Dedy , Hermansyah Hermansyah 
Published: December 2023

Improving the physical properties of problematic soil has became fundamental consideration in various constructions, especially geotechnical engineering, to avoid failures, increase stability and strength of soil. Silty sand is one of the problematic soils and often encountered in the field where the fine gradation contained in the soil allows the soil to easily deform under pressure and lateral forces. In this study, silty sand was mixed with three variations of crumb rubber content (5, 10, and 15% based on soil weight), 6% cement (based on soil weight), and 0.05% graphene oxide (based on cement weight) to measurement and analysis of physical and mechanical properties. Soil Consistency limits, compaction testing using the Proctor Apparatus, and direct shear test were carried out for each mixed variable. The test results showed that the consistency limits and dry density decreases with increasing rubber content in the soil-cement matrix containing graphene oxide. Substitution of graphene oxide into the soil-cement matrix was able to increase in the stress and shear strength of the soil at each in variation in rubber content.
Concrete corrosion in nuclear power plants and other nuclear installations and its mitigation techniques: a review
Authors: Rasheed Pathath Abdul , Nayar Sunitha K , AlFantazi Akram 
Published: December 2023

Abstract
Nuclear power plants (NPPs) have been affected by various failures through corrosion which causes economic losses, increased chance of the radiation exposure and environmental risk. One of the major durability issues in reinforced concrete is the corrosion of reinforcement which significantly reduces the life of reinforced concrete. Considering the increasing demand for longer service lives of NPPs, and the high cost involved in building and maintaining it, adequate preventive measures should be followed to minimize the corrosion. This review majorly discusses about the mechanism of corrosion of steel in NPP structures with emphasis on the mechanisms relevant to NPPs, possible reasons for the concrete corrosion as well as potential failure happening in NPPs. The majors reason for the concrete corrosion in nuclear power plants are mainly corrosive external and internal environment, thermal and mechanical stress, moisture content, microorganisms and stray electrical currents. The corrosion of NPPs may result in loss of structural integrity and leakage of radioactive material. The review also discusses about various corrosion prevention and protection techniques against concrete corrosion and concludes with an overview of present methods and possible future perspectives used to enhance the efficiency of concrete corrosion mitigation methods with focus of NPPs.
PharmoCo: a graph-based visualization of pharmacogenomic plausibility check reports for clinical decision support systems
Authors: Raupach Lena , Königs Cassandra 
Published: December 2023

Abstract
The first approaches in recent years for the integration of pharmacogenomic plausibility checks into clinical practice show both a promising improvement in the drug therapy safety, but also difficulties in application. One of the difficulties is the meaningful interpretation of the text-based results by the medical practitioner. We propose here as an appropriate and sensible solution to avoid misunderstandings and to include evidence-based, pharmacogenomic recommendations in prescriptions, which should be the graph-based visualization of the reports. This allows for a plausible interpretation and relate complex, even contradictory guidelines. The improved overview over the pharmacogenomics (PGx) guidelines using the graphical visualization makes the medical practitioner’s choice of dose and medication more patient-specific, improves the treatment outcome and thus, increases the drug therapy safety.

Published: December 2023

This paper considers the technological process of preparing carbamide-ammonium mixture using a multifunctional homogenizer assembly. The study object is the work process in the flow part of the multifunctional homogenizer assembly. Carbamide-ammonium mixture is used to feed plants with nitrogen, which is one of the main macro elements necessary for their growth and development. Nitrogen contributes to the formation of proteins, enzymes, and other important organic compounds, which are necessary for healthy plant growth and crop formation. Production of carbamide-ammonium mixture includes several stages, such as mechanical, hydromechanical, thermal, mass exchange, and chemical processes. To optimize these processes, a multifunctional homogenizer assembly of the rotary-dynamic principle of action was designed, which is capable of simultaneously performing all stages of carbamide-ammonium mixture preparation. A test bench was constructed to study the process of preparing carbamide-ammonium mixture and the sample was analyzed for nutrient content. The designed unit is capable of preparing about 30 liters of ready-made KAS-32 mixture in 10 minutes. The energy indicators obtained as a result of parametric tests are: head H=22.1 m, power N=27 kW, with productivity Q=5 m3/h. The use of such technology makes it possible to implement the principles of precision agriculture under the conditions of small-scale production, thereby increasing the efficiency of land cultivation. There is also the possibility of using equipment of this type for other needs, for example, for the preparation of liquid complex fertilizers and growth stimulants based on humates. Further development based on this assembly includes the construction of an automatic component supply line and the formation of a closed production cycle system

The article is devoted to the study of a nitrogen supply system for cooling an experimental device designed for testing in a pulsed reactor with a graphite moderator. To analyze emergency situations caused by disruption of the nitrogen supply system in the cooling paths of the fuel assembly cover and the experimental device power housing, a mathematical model has been developed to describe thermodynamic processes in a system of interconnected tanks that simulate individual sections of the experimental device hydrodynamic cooling system in a pulsed graphite reactor and implemented in the mathematical interactive package for engineering calculations in MATLAB/Simulink. To study the normal operation of the system and analyze possible emergencies, the cooling system of the experimental device was presented in the form of groups of interconnected sections of the hydrodynamic system-tanks, with specified volumes and hydraulic resistances of pipelines connecting these tanks. Verification of the model, calculations of the experimental device cooling system normal operation mode, calculations of emergency situations caused by a violation of the nitrogen supply system normal operation in the cooling paths of the fuel assembly cover were carried out, in particular, it was found that for the cooling system of the experimental device WF-2, the breakdown of the gearbox P-12 can cause depressurization of the fuel assembly cover and an increase in pressure in the power housing, the opening of the safety valve prevents exceeding the pressure limit in the housing, the device maintains integrity even in emergency situations, without being subjected to destruction of the power elements of the structure at a pressure of up to 8 MPa
