Authors: Irlayici Cakmak Pinar , Akturk Berkay
Published: July 2024

While initial costs in building economics cover a small portion of the costs incurred during its life-cycle, most occur in construction, operation, and subsequent processes. Despite its numerous contributions to building economics, the construction industry is slowly adapting to digital technologies. To overcome the barriers and crown the assets with their proper management, dynamic applications of digital tools and techniques of Industry 4.0 need to emerge in the construction industry. Therefore, this study aims to present an integrative approach that combines quantitative and qualitative analysis techniques to critically review the available literature on the potential contributions of digital construction technologies to building economics through the post-design phases of the life cycle. The primary focus of the investigation is how digital technologies can overcome prevalent problems and how they can impact building economics. The study contributes to the field by providing an awareness that will inform researchers and practitioners of the trends, gaps, and more profound exchange of ideas in future research efforts.
Editorial: Special Issue - Economics in Digital Construction
Authors: Kapogiannis Georgios
Published: July 2024

Welcome to this special issue of our CEB journal, dedicated to exploring the multifaceted economic dimensions of digital construction within the Architecture, Engineering, Construction, and Operation (AECO) sector. As digital technologies increasingly spread throughout this sector, they bring about transformative impacts not only on how projects are designed and managed but also on the broader economic landscape. The rapid adoption of technologies like Building Information Modelling (BIM) and digital asset management systems has set a new paradigm in project efficiency and data utilisation. These advancements promise substantial economic benefits, ranging from increased productivity to enhanced decision-making capabilities, which, in turn, can spur significant growth in the broader economy. However, efficient and fair distribution and diffusion of these benefits in society is not always given, as stronger economies can more efficiently utilise the benefits of Digital Construction compared to weaker economies. Consequently, there is a need signaled for structural reforms in the latter, to improve the rate of integration of digitalisation in the construction sector (Kapogiannis, et al., 2023). Climate change is also a factor that now poses challenges for the construction sector, with digitalisation a key element able to address these challenges.

Published: July 2024

Purpose: The study is the first part of a series presenting the primary results of multijoint hip flexion resistance training biomechanical investigation. The series evaluates the exercise in the context of possible implementation in hip flexors
shortening and hypertension. The described exercise was designed to use muscle hypertrophy as a solution for pelvis stabilizing muscles’ imbalance. This study aims to evaluate the work performed and power generated during hip flexion resistance training using two established methods and investigate the potential of IMU sensors as a cost-effective tool for measuring individual performance and progress in non-laboratory settings. Methods: The study was conducted with the use of training equipment constructed according to patent P.435615 allowing for the application of downward directed force to feet while performing hip flexion. Thirteen healthy students (7 females
and 6 males, body-height 176.00 ± 12.54 cm, body-mass 73.69 ± 18.08 kg, age: 21.77 ± 1.09 years) took part in the training session using three different additional loads (0, 2.5, and 5 kg). Techniques applied in the study included optical kinematics capture, strain gauges, and inertial sensors. Results: The average work of (TENS/IMU) were 56.57 ± 12.00 / 58.13 ± 13.07 - 76.54 ± 13.88 / 74.40 ± 13.93 J and an average power of 23.22 ± 6.43 / 23.65 ± 7.12 - 31.51 ± 9.42 / 31.62 ± 10.60 W were calculated for the additional load of 0 kg and 5 kg respectively. The correlation between values calculated with two tested methods was high both for power (R= .85 P< .001) and work (R= .86 P< .001).
Conclusions: Referenced data indicate a good correlation between the two methods but prove the need for further improvement of IMU-based method precision. It also allowed to determine a potential baseline of 15kg additional load for 1RM tests maximal value.

Moroccans’ Perceptions and Attitudes Towards radio Mohammed VI of the Holy Koran
Authors: Nabil Hamid
Published: July 2024

In 2002, the Moroccan communication authorities laid the legal platform of the audiovisual liberalization project. Four years later, the media landscape witnessed the birth of the first generation of private radio stations which were followed by the second generation three years later. Public media did no more benefit from the monopoly privilege. Instead, the media landscape was submerged by a constellation of alternatives attempting to forge a distinctive identity that would help achieve the largest audience. The real competition occurred between not only the private stations but also the public and private ones. This article examines the relationship between specialized media programs and the audience perceptions and attitudes. It puts under analysis the pioneering performance of radio Mohamed VI of the holy Koran as it is the only Moroccan radio station specialized in the Islamic religion. Throughout 11 years of broadcast, and with regard to the audience rate measurement bulletins, the station has consistently managed to outrun the others by realizing the highest audience rates. The study is based on field research that investigates the elements and reasons behind the station’s success; it also uses the conclusions and implications as references to scrutinize the dyadic relationship between Moroccans and their Muslim identity. The study is inspired from the audience rate bulletin published by Radio CIRAD which has confirmed it as a leading media model. This finding has also been solidified by the population sample that took part in the present study. The study adopts the mixed approach bringing together both quantitative and qualitative research instruments. The former includes CIRAD’s statistical platform whereas the latter refers to semi structured interviews recorded with 50 participants. The study seeks to answer two research questions namely (i) What are Moroccans’ perceptions and attitudes towards Radio M6 of the holy Koran? (ii) What are the underlying reasons behind its prevalence?

Published: July 2024

The disease known as esophageal varices is usually caused by portal hypertension. Portal hypertension is most commonly caused by extrahepatic portal vein thrombosis and other conditions, such as cardiac problems or hepatic cirrhosis. Clinical manifestations of esophageal varices can include melena, haematemesis, and gastrointestinal bleeding. Effective venous pressure reduction is achieved via the distal splenorenal shunt. We acquired the literature for our review from PubMed and Google Scholar. The search was done in English using terms that indicated a connection between improvements in bone grafting methods and the restoration of alveolar clefts. To expand the search results, we also looked through the papers cited in the literature. Almost all of the five gathered articles demonstrated that the distal splenorenal shunt (DSRS) is a beneficial surgical treatment that effectively avoids postoperative PH issues. Finally, DSRS is presented as a surgical long-term treatment for variceal esophageal reflux disease and portal hypertension. Because DSRS selectively decompresses the venous collaterals around the stomach and lower esophagus, it is a safe and effective therapy choice for decreasing bleeding over nonselective shunting surgeries as a selective shunt.

Do the equilibrium constants have units? A discussion on how general chemistry textbooks calculate and report the equilibrium constants
Authors: Quílez-Pardo Juan
Published: July 2024

An analysis of the literature concerning the dimensionality of equilibrium constants reveals that this topic manifests as a controversial issue. Based on this previous examination, this work studies if general chemistry textbooks accurately define and calculate equilibrium constants. In order to evaluate those textbooks, in the first part of this study the experimental equilibrium constants, Kp and Kc, and the thermodynamic equilibrium constant, Kº, are defined. Also, the equations that relate each constant to the other two are given. In the specific presentation of these quantities, an example is discussed both performing their accurate calculation and reporting them using the proper units. In the second part of this study, it is examined the way both first-year university chemistry textbooks and pre-university chemistry textbooks determine equilibrium constants, concentrating on how they handle the units of these quantities. Many textbooks treat Kp and Kc as dimensionless quantities. This misleading assumption is caused by a problem in the terminology used as in many cases Kp (or Kc) plays the role Kº. In order to avoid this misleading treatment of the equilibrium constants some suggestions are provided.
Modeling the Mole Understanding with Mathematical Reasoning
Authors: Sokolowski Andrzej
Published: July 2024

The amount of substance, expressed in the units of moles is an essential concept in chemistry and physics. Students entering physics courses usually possess a chemistry background. However, this study showed that their understanding of units of matter on the microscopic level is fragile, and needs improvement. Research shows that the complexity of interpretations of quantities expressed as ratios; molar mass or atomic mass makes formulating a dimensional analysis or proportion of these ratios unclear to students. Based on these findings, this study proposes applying equations of fundamental constants and proportional reasoning, instead of ratios, as the main building blocks to formulate conversion algorithms. In the line of that, a deductively designed lecture was delivered to a group (N=25) freshman college physics students. While on the pretest, only (N=4, 16%) correctly converted a mass of a substance expressed in kilograms to a number of moles, on the posttest the percentage of correct answers increased (N=20, 80%) suggesting that proportional reasoning coupled with fundamental constants brings clarity to the process and improves its understanding.

Published: July 2024

The purpose of this study was to examine the effect of certain variables chosen (gender, financial state of the family, educational background of the parents, a computer available for use at home and the number of siblings) and technology-supported project-based learning approach applied in the physics course on 11th-grade students’ attitudes towards computers and to evaluate the participating students’ views at the end of the study about the applications they actively took part in. In order to determine the students’ attitudes towards computers, the computer attitude scale was used. The study was carried out with thirty two 11th-grade students in the academic year of 2009-2010. Before starting the applications, the computer attitude scale was applied to the students as a pre-test. The three-hour physics courses were executed with simulations and animations in two course-hours and with the project-based learning approach in the other course-hour. At the end of the applications, the computer attitude scale was applied to the students as a post-test. In order to determine the students’ views about the process as well as about computers, semi-structured interviews were held with them. The results of the analysis demonstrated that there was a significant difference between the computer attitude mean scores of the students before and after the experimental process in favor of the post-test mean scores. But, there were no differences among their attitude scores according to certain variables. The interviews held with the students revealed that the students had positive views about the process and computers.

Does the computer-assisted teaching method as effective as the laboratory-assisted teaching method on student physics achievement and attitude towards physics? To seek for answering this question is the aim of the present study. The computer-assisted teaching method of the study includes the programs of Crocodile Physics and Edison 4.0 in the subject of “simple electric circuits” on 9th grade level. By using the experimental pre-test/post-test, experimental-control group design, “Physics Achievement Test” and “Physics Laboratory Attitude Scale” administered two times as pre-test and post-test were used as the data collection tools and they were administered to 50 9th grade students. The data were then analyzed by using SPSS 16.0 statistical analysis program and statistics such as mean, Standard Deviation were calculated and independent t-test statistical techniques were used. According to the data analysis, there is a significant difference on students’ physics achievements in favor of the computer-assisted teaching method and also both for two different teaching methods there is a significant difference on students’ attitudes towards physics. Thus, it can be said that to develop students’ physics achievements and attitudes towards physics using the computer-assisted teaching method can be more effective than the laboratory-assisted teaching method.

Authors: Uluçınar Sağır Şafak , Kılıç Ziya
Published: July 2024

Observing the argumentation of a scientific event and understanding skill is an important component of scientific literacy. In this paper, the effect of lecturing with argumentation-oriented activities in science classes on student success and the retention of knowledge has been analyzed. The study was conducted between 2006 and 2008 academic years in an elementary school in Amasya, Turkey. The study employed a quasi-experimental research method. Argumentation based teaching method was used in experimental group. Traditional teaching method was used in control group. Two different tests were developed for data collection in the study. A subject-related success test was developed in order to determine the success of students and a preliminary knowledge test was developed to check whether the classes were equivalent and to determine their preliminary knowledge. It has been found out that there was a significant difference in favor of the experimental group in terms of student success and the retention of knowledge. When experimental groups worked on for two years were compared, no significant difference was detected between student success rates; however, the scores of second year experimental group were found to be higher. It can be said that argumentation based teaching model affects students’ development of conceptual understanding and their information permanence. Argumentation can also be employed in teaching other subjects. Class activities have to be developed and argumentation norms have to be applied in science teaching so that young individuals can gain confidence in employing argumentation.

Published: July 2024

One of the key points in Late President Yar’adua’s 7- point agenda is the accomplishment of qualitative and functional Education. This can be monitored through assessing academic achievement of students. Chemistry Education occupies a central position to all disciplines. This study examined the correlates between age and gender on academic achievement (CGPA) of Chemistry students. The study used thirty six (36) females and forty (40) males giving a total of sample seventy eight (76). Scatter – plot, mean and standard deviation were used for the descriptive statistics while univariate analysis of variance (ANOVA) and multiple regression were used for inferential statistics. T-test was used to test the null hypothesis formulated (P<0.05). Result revealed a linear relationship between, age-CGPA and gender-CGPA.A low positive correlation coefficients was obtained for ages and gender (r=0.006 and 0.105) which were not significant. The predictor variables jointly accounted for 1.1% of the variance, age was the better predictor. The null hypothesis tested was accepted implying no significant difference in academic achievements of students. It was suggested that some more variables be included so as to determine significant correlation of students’ academic achievement of Chemistry students.
Chunking in Chemistry
Authors: Zhilin Denis M. , Tkachuk Larisa E.
Published: July 2024

Experts (2 groups, 41 participants) and non-experts (7 groups, 130 participants) in chemistry were exposed to sequences of chemical symbols for 30 seconds and then, after a minute, wrote them down. Four sequences were real chemical equations and four sequences were fakes got from the equations by random mixing the symbols. Experts in chemistry recalled real chemical equations (a) much better than fake sequences and (b) better than novices in chemistry. Meanwhile, no significant difference was found between the experts and the novices in recalling the fake sequences. Besides, the novices remember both real and fake sequences symbol-by-symbol from left to right, the frequency of mistakes increasing in the same order. The experts remember real equations as a whole and chunk some chains in the fake sequences remembering them better than others. All these results provide evidence that experts chunk chemical information and allow extending the chunking-based theories to chemistry teaching.
An Investigation of Teacher Response to National Science Curriculum Reforms in Turkey
Authors: Elmas Rıdvan , Öztürk Nilay , Irmak Meltem , Cobern William W.
Published: July 2024

Major science education curriculum reform is taking place in Turkey involving a substantial break with past science curricula. Such reform has significant implications for teachers but to date there has been little research on teacher response to these reforms. The purpose of this qualitative study was to investigate the impact on the teachers who are charged with implementing reforms. Semi-structured interviews with 18 elementary science teachers were conducted and additional observational data was recorded. The interview schedule comprised 23 questions in 9 themes. According to the data analysis, the main problem for teachers is that curriculum reforms involve overly big innovative ideas within unrealistically short timelines and with limited economic investment in human resources and supporting materials. In addition, there is a lack of organization and coherence between system stakeholders. Another drawback is the very centralized educational system and the idea that change can be driven from the top down.

The Orangist Appropriation of Erasmus
Authors: Steen Sanne
Published: July 2024

The attribution of an Erasmian spirit to William of Orange is tenuous but has nevertheless been made consistently since the early twentieth century. This article makes use of reception theory to connect this association to events of the early nineteenth century that happened in response to the French dominance in the Netherlands and their subsequent expulsion. In 1810 and 1813 Rotterdam Orangists and opponents of the French presence appropriated the Erasmus statue in the city for their own cause by adorning it with orange accessories and by attaching short verses to it. The repetitive recollection of these events throughout the nineteenth and early twentieth century culminated in the attribution of an Erasmian mind to William of Orange, who was himself associated with Orangism as of the twentieth century. While the initial Orangist actions were local and public endeavours, the association gradually entered the national political and academic sphere in the twentieth century. This transfer is exemplary for the changeability of ‘isms’ such as Orangism and Erasmianism. This article therefore ultimately emphasizes that besides the caution it requires, this changeability provides opportunities for reception histories.
Hopfield Type Phase Neural Network
Authors: Крыжановский Б. В.
Published: July 2024

исследованы свойства полносвязной нейронной сети, построенной на фазовых нейронах по правилу Хэбба. Сигналы, протекающие по межсвязям сети, представляют собой единичные импульсы с определенными фазами. Решающее правило срабатывания нейрона задается следующим образом: в суммарном сигнале, поступающем на вход нейрона, выделяется фазовая компонента с наибольшей амплитудой, и нейрон испускает единичный импульс с такой же фазой. Фазы, кодирующие компоненты векторов ассоциативной памяти, распределены случайным образом. Для оценки ошибки распознавания применяется техника Чернова–Чебышёва, не зависящая от типа распределения кодирующих фаз. Показано, что объем ассоциативной памяти такой нейросети в четыре раза больше, чем у классической сети хопфилдова типа, оперирующей бинарными паттернами. Соответственно, в четыре раза больше и радиус области притяжения.

this study examines the properties of a fully connected neural network composed of phase neurons, following the Hebbian learning rule. The signals transmitted through the network’s interconnections are single pulses with specific phases. A neuron’s firing rule is defined as follows: among the total signals received at a neuron’s input, the phase component with the highest amplitude is identified, and the neuron emits a single pulse with the same phase. The phases encoding the components of associative memory vectors are randomly distributed. To estimate the recognition error, we employ the Chernov-Chebyshev technique, which is independent of the phase encoding distribution type. Our findings demonstrate that the associative memory capacity of this neural network is four times greater than that of a traditional Hopfield network that operates with binary patterns. Consequently, the radius of the attraction region is also four times larger.

Metodologia: Revisão integrativa de literatura. As bases de dados eletrônicas utilizadas foram PubMed, SciELO e BVS. Foram incluídos estudos publicados em português e inglês, que abordaram intervenções fisioterapêuticas em gestantes asmáticas. Foram excluídos estudos que não apresentaram resultados claros ou que fossem revisões narrativas. Os dados foram analisados de forma qualitativa, destacando as intervenções fisioterapêuticas que demonstraram maior eficácia. Os principais resultados foram discutidos à luz da literatura existente, destacando as implicações clínicas e sugerindo direções para futuras pesquisas. Resultados: As principais intervenções identificadas foram exercícios respiratórios, exercícios físicos controlados, uso de dispositivos de pressão positiva expiratória e técnicas de relaxamento. Os estudos mostraram que essas intervenções contribuíram para a melhora da função pulmonar, redução da dispneia e alívio das dores musculoesqueléticas associadas à gestação. Além disso, houve uma diminuição na frequência de crises asmáticas e uma melhor qualidade de vida relatada pelas gestantes. Os resultados indicaram que as intervenções fisioterapêuticas foram eficazes no manejo da asma em gestantes, contribuindo significativamente para a saúde respiratória e o bem-estar geral das pacientes. A prática regular de exercícios respiratórios e físicos ajudou a aumentar a capacidade pulmonar e a eficiência respiratória, enquanto as técnicas de relaxamento reduziram o estresse e a ansiedade, fatores que podem desencadear crises asmáticas. A utilização de dispositivos de pressão positiva expiratória mostrou-se benéfica na melhora da ventilação pulmonar e na redução da retenção de secreções. Podemos concluir que as intervenções fisioterapêuticas não apenas melhoram a função respiratória e reduzem a frequência de crises asmáticas, mas também promovem um parto mais tranquilo e um período pós-parto mais confortável. Futuros estudos devem continuar a explorar novas intervenções e aprimorar as existentes, visando sempre a melhoria da qualidade de vida dessas pacientes.

Abstract. To investigate the historical levels of atmospheric ammonia (NH3) pollution in south-eastern Europe, a 182 m long ice core was extracted from Mount Elbrus in the Caucasus, Russia. This ice core contains a record of ammonium (NH4+) levels from ~1750 CE (Common Era) to 2009 CE. The NH4+ ice core record indicates a 3.5-fold increase of annual concentrations from 34 ± 7 ng g-1 (~1750–1830) to 117 ± 23 ng g-1 over the recent decades (1980–2009). The increase remained moderate until 1950 CE (mean concentration of 49 ± 14 ng g-1 over the 1830–1950 period), and then accelerated to reach a maximum close to 120 ng g-1 in 1989. This ice core trend is compared to estimated past anthropogenic NH3 emissions in Europe by using state-of-the-art atmospheric transport modeling of submicron aerosols (FLEXPART model driven with 0.5° x 0.5° ERA5 reanalysis data). It is shown that in summer, when both vertical atmospheric mixing and agricultural NH3 emissions are strengthened, the NH4+ ice core trend is in good agreement with the course of estimated NH3 emissions from south-eastern Europe since ~1750 with a main contribution from south European Russia, Turkey, Georgia, and Ukraine. Examination of Mount Elbrus ice deposited over the second half of the 18th century when agricultural activities were less than 10% of those during the 1990s, suggest a pre-1750 annual NH4+ ice concentration related to natural emissions of 25 ng g-1. This pre-1750 natural level mainly related to natural soil emissions represents ~20% of the 1980–2009 NH4+ level, a level mainly related to current agricultural emissions that almost completely outweigh biogenic emissions from natural soils.
Atmospheric Pressure Measurement Using a Smartphone

We believe that laboratory work deepens students' understanding and makes meteorology theory more directly relevant to the real world. In meteorology, the hydrostatic equation relates the pressure difference between two altitudes to the weight of the air column between those altitudes, which is determined by air density, gravitational acceleration, and the change in altitude. Therefore, we can compute the pressure difference based on the air density (1.293 g/m³ at STP), gravitational acceleration, and the known altitude difference.We incorporate laboratory activities using an iPhone, as modern smartphones have various applications that can indicate altitude and atmospheric pressure. Since our laboratory is located in a five-story building with a fire exit staircase and an open-air atrium, students are asked to measure the atmospheric pressure and altitude on each floor of both locations.First, the students plot the measured altitude versus the corresponding atmospheric pressures. The results should show a linear relationship between altitudes and pressures for all data. This is because a smartphone's application computes the altitude based on the measured pressure value, assuming a constant temperature.As we know the actual altitude of each floor in our building from the building's blueprints, students are asked to plot the known altitude of each floor versus the measured pressures. This time, they will find a linear relationship for both the fire exit staircase and the open-air atrium, but they will notice differences in the slopes of the linear regression lines for each location. The difference in slope is due to the temperature difference, as inferred from the hydrostatic equation and ideal gas law. As an extension, students may take data in the morning and afternoon and then compare the results to observe any potential temperature effects.Using the air density at STP and the known altitude difference, students can compute the expected pressure difference and then compare it with the measured value. The measured pressure difference should be smaller than the computed value. Asking why the measured value was smaller than expected will provide a good opportunity to confirm the students' understanding of the meaning of STP and the inverse relationship between air density and temperature.While pressure sensors in smartphones can accurately measure pressure differences, they cannot obtain absolute pressure values. Based on our experience, the accuracy of pressure difference measurements is generally quite good, but some phones may show strange results. Therefore, it is recommended that students work in groups, compare their data within the group, and collaborate on writing a report.Our experiment was initially designed for in-person laboratory activities in regular classes. However, the experiment can also be adapted for students working remotely in an online course setting. The designed activity can be implemented in a high-rise apartment building and/or a large shopping mall.
Quality Aspects of Effective CAP-based Early Warning Systems

Published: July 2024

The Common Alerting Protocol (CAP) is a key XML-based standard (ITU-T Recommendation X. 1303, governed by the OASIS Emergency Management Technical Committee, EMTC) for alerting all-hazards via all-media and one of the backbones of the UN Early Warnings For All (EW4All) Initiative. Several high level documents refer to "high-quality of CAP alerts" needed in order warning messages are able to reach as many people at risk as possible in near real-time and via various channels, including re-distributors such as Google, Apple or mobile alerting techniques such as Cell Broadcast (CB). Yet comprehensive guidelines for designers and developers of CAP-based Early Warning Systems are lacking, especially when it comes to the quality aspect of CAP alerts, leading to various obstacles when developing and deploying integrated CAP-based Early Warning Systems. Among other factors, this creates a considerable knowledge gap, significantly impacting the effectiveness of Early Warning Systems and hindering the development of open source solutions and thus sustainability of investments from donor organizations. This contribution provides an overview of what CAP is, what advantages and challenges are associated with CAP, how CAP alerts are generated and aggregated at regional and global level, which contentwise and technical aspects are needed to be met to ensure high-quality of CAP alerts, specific requirements of major re-distributors as well as recent initiatives and publications in that wider field. Finally key actors involved in the Early Warnings For All initiative are invited to jointly work on guidelines and common practices towards effective CAP-based Early Warning Systems outputting high-quality CAP.
