Exploring Variations in Abstract Writing Formats and Structures Among Ph.D. Students

Background: 
 The introduction, a crucial component of any research paper, must be well-written so that readers can evaluate its quality. A typical five-paragraph abstract includes an introduction, objective or purpose, methodology, findings/results, and conclusion. However, not all Ph.D. candidates follow this structure and format when writing their abstracts.
 Methodology: 
 The purpose of this study was to identify and describe variations in abstract writing formats and structures among Surabaya state university Ph.D. candidates. Using a qualitative descriptive methodology, the researchers analyzed 15 dissertation abstracts: eight from the Faculty of Civil Engineering and Planning at FTSP-ITS and seven from the Medical Science department at Airlangga University Surabaya. They examined the number of paragraphs and the structure of the abstract in each.
 Findings: 
 The study indicated various abstract structures and writing formats: 40% of the abstracts had three paragraphs, 26.66% had five paragraphs, 20% had four paragraphs, and 13.33% had one paragraph. In terms of abstract structure, 60% lacked a conclusion, 33.33% lacked an objective, 26.66% lacked all five abstract structures, 26.66% lacked both the objective and the conclusion, and 6.66% lacked an introduction.
 Conclusion: 
 In conclusion, the study found several variations in dissertation abstract writing formats regarding both paragraph count and abstract structure.
 Originality: 
 The novelty of this study rests in its focus on analyzing variations in abstract writing formats and structures among Surabaya state university Ph.D. candidates. By examining 15 dissertation abstracts from various faculties, this study sheds light on the inconsistencies and deviations from the standard format and structure of abstracts, which may impact readers' ability to comprehend and evaluate research papers. This study contributes to a better understanding of how Ph.D. students' abstract writing practices vary and identifies potential enhancement areas.

Experimental Analysis of Thermo-Technical Parameters of Windows Glazing in the Pavilion Laboratory

Improving the energy performance of buildings in the context of external climatic conditions and the requirements of indoor environments is a hot topic in the construction industry. It primarily concerns reducing the energy used for heating and cooling in buildings. In the EU sector, this is addressed by the Energy Performance Directive (EPBD), which is followed by relevant national standards. The energy performance of buildings is strongly influenced by the window structures that are part of the building envelope. Their influence on energy performance is represented by the heat transfer coefficient, which differs in the actual built-in window construction from the design value given by the manufacturer. In this paper, the authors deal with its measurement in situ using the heat flux measurement method. The measurement was carried out in the pavilion laboratory of the Department of Building Engineering and Urban Planning (DBEUP), Faculty of Civil Engineering (FCE), University of Zilina (UNIZA), on three window constructions of different material bases. During the measurements, surface temperatures on the glazing, heat flux density, and air temperatures were recorded in minute increments. The influence of the year-round cycle of the outdoor environment on the embedded window structures is presented and the results are presented in the conclusion of the paper.

Flat Roofs Renovation Planning on Public Buildings Using Fuzzy Multi-Criteria Analysis

Renovation of flat roofs typically involves repairing or replacing the existing roof to improve its performance and extend its lifespan. The renovation process may include a range of tasks depending on the condition of the roof, such as repairing leaks, replacing damaged or deteriorated materials, adding insulation, or upgrading drainage systems. This research aim was to establish the priority of renovation of flat roofs of the public building based on the principles of multi-criteria analysis and fuzzy set theory, using the multi-criteria method PROMETHEE II in fuzzy logic form (F-PROMETHEE II). The proposed approach is adequate due to its ability to transform the uncertain and vague information received from an expert into a fuzzy number. This way, the objective outcome can be obtained, the criteria conflict removed and the alternatives ranking and mutual comparison enabled. It was necessary to analyze the existing literature, the flat roofs of a public building in terms of their current condition, and define the main goals and criteria for the roof renovation project. Based on the defined goals and criteria, the roofs are evaluated and ranked according to the priority for renovation. The planning process of renovation of flat roofs was carried out specifically on the building of the Faculty of Civil Engineering, Architecture and Geodesy in Split.

Editorial to the Special Theme Sustainability

Sustainability represents a commonly agreed global development goal. It aims at ensuring the quality of life on Earth for current and future generations. Sustainability should thus become the fundamental overarching concept for the efficient/high-quality design and operation of any product or service throughout its lifecycle—focusing on all three pillars of sustainability—social, environmental, and economic. Among the different socioeconomic sectors, dealing with the impacts that the construction sector has is fundamental, as it strongly contributes to many of the pressing issues that need to be addressed. Not only do we need to improve the economic, environmental, and social performance of our built environment, but we also need to be better prepared for new conditions that are appearing as a cause of global challenges (e.g., climate change). The importance of this approach is all the more clear in light of an increasing number of man-made and natural disasters occurring globally. Thus, current developments and changes in the environment and socioeconomic situation require improvements in the technology of different processes that are involved in construction projects. In this context, concrete is a particularly interesting material, because it has a great potential for new technical solutions meeting new requirements, leading to the necessary reduction of environmental impacts and at the same time improvement of social and economic conditions, including safety and reliability during emergency situations. However, considering the huge volume of global concrete production and the negative impacts closely linked to its production, the overall environmental negative impact associated with the construction of concrete structures on a global scale is considerable. In view of the above global situation, it is of utmost importance to focus on the introduction of new production and construction technologies, advanced design techniques and efficient operation, maintenance, and recycling techniques of concrete structures. Concrete mixes, concrete products, and concrete structures should be designed to meet the requirements of sustainability—namely, to minimize their negative impacts and increase the positive impact on society, the environment, and the economy. This could be achieved by increasing the quality and durability of concrete structures throughout their life cycle, through (i) improvements in design methods, (ii) development of concrete mixtures, composite materials, and reinforcement methods, (iii) modernization of concrete technology, (iv) development of integrated design approaches, and (v) innovation in maintenance, repair, demolition, and recycling processes. This requires the involvement of all actors in the construction process, from material manufacturers, designers, and builders to users, and their conviction and initiative in the need to achieve better results in terms of sustainability requirements. This special theme of Structural Concrete journal: Sustainability of Concrete Structures collects a selection of contributions related to different aspects of sustainability showing potential of concrete structures to contribute to the achievement of the Sustainable Development Goals (SDGs) set by the United Nations in 2015 as an action plan until 2030. The content of this special theme volume covers issues related to Life Cycle Assessment of concrete structures, carbon neutrality, use of recycled concrete and other recycled components, optimization of concrete structures, and many other issues bringing the contribution of concrete research and development to SDGs. We trust that the presented selection of articles is of interest to the concrete community focusing on the development of concrete structures toward a sustainable and resilient built environment as a contribution for future generations.

Exploration and verification of fourth industrial revolution generic skills attributes for entry-level civil engineers

<span lang="EN-US">The fourth industrial revolution (4IR) requires the workforce to be equipped with new skills when existing skills need to be upgraded or improved because they are no longer in line with technological advancement in 4IR. Thus, it is crucial to determine what the new skills or 4IR skills are that can help the future workforce obtain a job after graduation. This study aimed to explore and verify the attributes of nine 4IR generic skills (GS4IR) for entry-level civil engineers in Malaysia by using a qualitative approach. An interview session was conducted with five senior engineers in the civil engineering (CE) field and three experts (two engineers in CE and one lecturer in CE faculty) for reliability data verification. The interview data were analyzed using coding analysis and presented in a matrix table. The results show 76 items identified as attributes of nine GS4IR constructs. Next, the verification of the constructs and attributes of GS4IR was obtained from Fleiss Kappa's reliability analysis to determine the overall approval index. The results of the analysis revealed an overall Kappa coefficient value of 0.61, which indicates a good level of agreement. The findings of this study consist of 58 attributes for nine constructs of GS4IR approved after the inter-rater reliability among the experts. The findings from this study are beneficial for the development of a framework of 4IR generic skills for civil engineering graduates as guidance to instill new skills in producing future engineers.</span>

Transformation of Delivery and Assessment for Laboratory Course During Covid-19 Pandemic: The Case Study of Soil Engineering Laboratory

Due to the spread of the COVID-19, many universities throughout the world are experiencing partial or complete disruptions to their academic programmes. As a result, more and more institutions are making the essential changes to their instruction in teaching and learning processes, including laboratory classes from face to face into a hybrid or online delivery format. Regardless of the actions done, lecturers must keep up their rigorous academic standards and offer a top-notch student as necessary for delivering the learning outcomes linked to courses especially laboratory courses that normally being conducted face to face in the laboratory or workshop to online or open distance learning (ODL). This transformation will present a challenge to academicians across the higher education sector, forcing them to switch from normal class delivery to online instruction and various laboratory delivery strategies. Students as a result will not receiving direct instruction from lecturers, and they have limited or no access at all to laboratory resources that necessary for delivering the learning outcomes linked to each programme courses. This paper reviews approaches taken by Faculty of Civil Engineering, UiTM and lecturers to deliver teaching and laboratory practices remotely, in consideration of the COVID-19 pandemic. This review is primarily focused on implementation on teaching delivery and laboratory assessments given to Civil Engineering Diploma Students in Soil Engineering Laboratory Course during COVID outbreaks. The findings of this study may be used to improve online engineering education during and after pandemics in other institutions or courses with a similar demographic.

Enhancing Student Understanding via Smart and Friendly Learning Mobile Application

In the sphere of education, testing and enhancing students' comprehension is not a simple process. This is mirrored in the assessment results, where particular courses have a high failure rate. On the UiTM system, the high failure rate is defined as the proportion of students who fail a subject that exceeds the threshold of 25 percent. Therefore, topics exceeding this limit are deemed incapable of meeting the Academic Quality UiTM objective. In this study, Basic Hydraulic courses is chosen to be a pilot study as the failure rate is high for few semesters. A creative strategy and method of teaching and learning is being proposed to increase students' understanding of the course’s content as to overcome the related issue. A smartphone application known as Sahabat Maya Pelajar (SMa2P) has been introduced and integrated into the teaching and learning process. According to the examination records of the Basic Hydraulics course at the Faculty of Civil Engineering at UiTM Johor, the failure rate of this course is decrease. This is shown by comparing results between semesters of 20204 and 20212 which indicate the course failure rate decreased by 22% in the latter semester. Therefore, it is crucial to improve students' performance and comprehension by using digital tools as this platform able to incorporate interactive teaching approaches into classroom activities through smartphone application.

Proposing a framework for introducing the concept of engineering digitization to develop curricula: case study - Tishreen University, Faculty of Civil Engineering

The emergence of Building Information Modeling (BIM) technology has made a major development in the fields of engineering and construction and has provided a means for documentation and design management throughout the building's life cycle. Despite this, the construction sector suffers from a clear shortage of specialists equipped with work skills, and therefore there is a gap and lack of skills. In order to meet the future needs for the skills of using (BIM) technology in the labor market, it was necessary to take serious steps to introduce BIM in education programs in Syrian universities to prepare future specialists, so this study aimed to identify the current reality of teaching Building Information Modeling (BIM) and to identify obstacles and challenges that prevent the application of (BIM) and propose a framework for introducing the concept of engineering digitization to develop curricula at Tishreen University, Faculty of Civil Engineering. The study used the descriptive survey method, and to collect data, two questionnaires were developed, which were applied to a sample of (32) faculty members from all disciplines of the Faculty of Civil Engineering. The study also used the statistical package for social sciences (SPSS) program to analyze the results of the questionnaire. The study showed a positive awareness of the culture of building information modeling among the various disciplines of civil engineering, despite the presence of many challenges and obstacles facing the implementation of BIM, and the study provided a general framework for the integration of building information modeling (BIM) technology with curricula The most important recommendations indicate the need to enhance awareness of the BIM culture and its applications by offering specialized training courses for academics in the use of modern technological tools based on BIM as an effective educational tool that can be integrated into the teaching curricula.

Research Results on Structural Strengthening with FRP Composites : State of the Art from Timişoara

Twenty-five years ago, no one could have expected that the use of Fiber Reinforced Polymer (FRP) composites in construction would be so widespread and so successful. It needed dedicated people like Prof. György L. Balázs, who saw the potential in this material, clearly understood the limits of these solutions, and devoted a lot of time to popularizing, improving, and implementing standards for secure applications. When we are discussing research related to the use of FRP in construction performed in Timișoara, two important personalities must be mentioned. The first is Prof. Balázs, who, starting from 1998, supported the development of FRP research in Timișoara with his advice and active participation by guiding the first BSc and MSc thesis and then taking part as an opponent in the first PhD defended in this field. The second person is Prof. Stoian Valeriu, a dedicated professor and excellent structural engineer who recognized the opportunities of the FRPs and trusted in this research direction. In the last 25 years, he has brought up a generation, conducting nine successfully defended PhD theses and several MSc theses in this domain. Congratulations to both! This paper briefly tries to summarize the main research results obtained in the field of structural application of FRP materials realized in the past two decades at the Politehnica University of Timișoara, Faculty of Civil Engineering.

History of Fib International PhD symposia in civil engineering

The International PhD Symposia in Civil Engineering were developed to increase the international exposure of young researchers preparing their PhD Theses. It has been realised that the PhD students needed a particular forum above their PhD programmes to present and discuss the results of their ongoing research and to collect pieces of advice on how to continue the research. This forum should have been very similar to what we generally have for technical or scientific presentations and to collect opinions on a large scale. It is called PhD Symposium. Many thanks for the continuous support of CEB (Committeé Euro- International du Béton) then to fib (International Fedération du Béton). The PhD Symposium in Civil Engineering system was initiated by the Faculty of Civil Engineering at the Budapest University of Technology (BME) in 1996. Many universities have successfully followed this idea in Europe, North America and Asia.

Mentalno zdravlje studentske populacije tokom pandemije COVID-19

The COVID-19 pandemic has not only affected the physical but also the mental health and well-being, causing many mental problems in the population around the world. This paper is trying to offer answers to questions about the impact of the pandemic on the level of stress, anxiety, depression and life satisfaction of the student population. The survey was conducted as a cross-sectional study. The studied population comprised students of the Faculty of Mechanical and Civil Engineering in Kraljevo and the Kraljevo Medical College. The standardised depression, anxiety and stress self-assessment scale - DASS-21 was used as the survey instrument. The largest number of students felt the fear of one of their relatives getting infected (80.2%), that is of endangering their family (77.6%). Approximately one in three students felt the fear of death (34.4%), the fear of getting infected (29.7%) and of ending up in hospital (36.5%). One in six respondents felt vulnerable during the state of emergency (16.3%), and one in ten felt very vulnerable (9.8%). 14.6% of them stated that the epidemic had affected their student responsibilities a lot, and 22.3% of students expressed the negative impact of isolation on them. The results of our study indicate a high percentage of reported symptoms of stress (44.2%), anxiety (47.1%) and depression (34.9%) among the student population. Pandemic conditions have led to considerable changes in the daily life of all people, while the impact of the pandemic and the consequences that are yet to emerge still cannot be fully understood. That is why it is of utmost importance to take care of the mental health of those who are in a sensitive period of life.

Unravelling The Deposition of Indoor Microplastics at Various Heights Across Rooms

Microplastics (MP) are widely present in both outdoor and indoor environments. Extensive research has thoroughly documented the potential negative impacts of MPs on human health. This study utilized a deposited sample method for 3 weeks, with eight-hour daily exposures, using funnels and bottles to investigate the properties of MPs in the office and laboratory settings of the Faculty of Civil Engineering & Technology (FCET), Universiti Malaysia Perlis. The characteristics examined included the deposition rate, size, form, and colour of the microplastics. Samples were collected at three different heights. The samples underwent pre-treatment procedures, such as physical counting and categorization (size, colour and shape). Micro-Raman analysis was performed to determine the primary polymer types. The deposition rate in the office was found to be 4,960 counts/(m2.h), while the rate in the laboratory was 6,940 counts/(m2.h). Human activities and the appearance of synthetic materials, especially from textiles, play a big role in the deposition rate of MPs in the environment. During the day, the rates were higher than at night. The results of the study showed that indoor MPs come in many different colours, with transparent and black being the most common. About 42% of the size range of fibrous MPs was between 200 µm and 2000 µm, and more than 15% of the particles were between 20 µm and 200 µm. Most of the time, fragments were smaller than strands. The most abundance polymers detected in both rooms were polycarbonate (PC), pigments and polymethyl methacrylate (PMMA).

Verification of window properties after 10 years of exploitation: results of measurements in the pavilion laboratory and the climate chamber

The article will deal with the analysis of measured data on a plastic window with thermal insulating triple glazing, which is suitable for low-energy or passive houses. The window was installed in 2011 in the test laboratory of the Department of Building Engineering and Urban planning, Faculty of Civil Engineering, University of Žilina (Slovakia), where it was tested under standard indoor climate conditions and real outdoor climate conditions. Surface temperatures on the frame friezes and glass system and heat flux density were recorded at a five-minute time step. In 2020, the window was removed from the laboratory and subsequently tested in a climate chamber. This paper will present the results of these measurements in terms of heat flow density waveforms, heat transfer coefficient, and total solar transmittance through the glazing. Subsequently, a simulation model of this window will be created in the environment of a computational program and its verification based on the measurements will be carried out. A series of calculations will be performed on the tuned model and analyses of the results and comparisons will be presented under the same climatic conditions as during the real measurements recorded by the meteorological station.
