Published: July 2024

This paper presents an analysis of the moderating effect of turnover intention on the relationship between intrinsic motivation and the employee performance model. The moderation effect analysis was conducted using SmartPLS software version 3.0. The model was constructed within the software, and the analysis was conducted in two stages. The first stage involved a bootstrapping process to generate and determine the significance level and strength of the path. The second stage employed the PLS Algorithm process, generating a simple slope graph. Results from the bootstrapping process revealed a noticeable moderating effect attributed to turnover intention, supported by a t-statistics value of 2.514 and a statistically significant p-value of 0.006. Investigating the specifics of the path coefficient, the moderating impact on the relationship was quantified at -0.097, indicating a negative moderating influence. In practical terms, this suggests that turnover intention exerts a dampening effect on the connection between motivation and employee job performance. Regarding the simple slope analysis, it was found that the moderation effect of turnover intention on the relationship between intrinsic motivation and employee performance is particularly robust when turnover intention is lower. However, this effect diminishes to some extent when turnover intention is higher. These findings provide valuable insights into how the dynamics of these variables interact under varying levels of turnover intention.

Unpredictable weather, global warming, and even air pollution result from human activities that harm the ecosystem, whether we like it or not. Since the publication of the Brundtland Report, the adverse effects on the environment have been the focus of discussion by many parties. The Brundtland report highlighted that the current physical development practices have less emphasis on environmental protection while planning physical growth. Since then, the construction sector has gradually embraced many green practices, such as green procurement. The people capability requirements that are crucial for speeding the adoption of green-oriented procurement will, therefore, be highlighted in this paper. This study uses an exploratory technique to uncover the people's capability criteria for green procurement of a construction project. The identification of the criteria is novel Several focus group discussion sessions were conducted involving stakeholders from various backgrounds who have been involved with green buildings. The results of this study will help the project stakeholders to enhance people capability plans for the project development. The ultimate aim is to ensure all the green project objectives are carried out in line with the urgent need to protect the environment and support government policies.

Building information modelling (BIM) has been theoretically proven to enhance the integration of design, construction, and operation processes, hence improving the holistic delivery of a construction project. Despite the many initiatives provided by the government across various countries to increase the uptake of BIM in project implementation, previous studies have discovered the many barriers to successfully applying BIM, among which are legal and contractual issues. Hence, the present study explores and reviews the current legal and contractual impediments that have restricted BIM-based applications in the construction industry. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were employed as a standard protocol for reviewing the current research in the existing literature. The overall search process resulted in a total of 44 articles, which were then thematically analysed to disclose the findings. The review derived eight key aspects, namely procurement method, contract documentation, time and cost, quality, coordination, liability, security and law and regulation and their respective subcomponents as the basis of legal and contractual impediments that could challenge the success of BIM application in construction projects. The study extends the existing knowledge of BIM application and the implications arising from its utilisation and offers some practical insights for design and construction practitioners to improve their roles, obligations, and compliance with BIM contractual requirements. Several recommendations are also made for future research on BIM functionalities for contract administration.

Published: July 2024

Structural strengthening is essential in civil engineering to ensure the integrity, safety, and longevity of various types of structures. Effective strengthening is required to solve these issues and lengthen the service life of structures as they naturally deteriorate with time. Hence, the use of various strengthening techniques to enhance the structural integrity of existing structures and infrastructure has gained prominence in recent years. This study demonstrates how Reinforced Concrete (RC) structures may benefit from Near-Surface Mounted (NSM) technology. The demonstration involves the experimental study on the performance of three different types of RC beams; unstrengthened RC beam, RC beam strengthened with NSM procedure using a conventional steel ribbed bar, and RC beam strengthened with NSM procedure using an iron-based smart memory alloy (Fe-SMA) ribbed bar. Consequently, three RC beams were evaluated at room temperature throughout the experimental testing, while the remaining three RC beams were examined after being exposed to a 200°C temperature exposure. The load-deflection, strain deformation and crack propagation were demonstrated to determine the behaviour of the RC beam. The experimental findings suggested that the performance of RC beams strengthened using NSM techniques was superior to that of RC beams that had not been strengthened. Although the results generally indicated a decrease in ultimate load obtained in the RC beams exposed to elevated temperature compared to RC beams tested at room temperature. It is shown that Fe-SMA RC beams performance better compared to steel strengthened RC beams. The RC beams strengthened with an Iron-based smart memory alloy ribbed bar recorded an increase in load-carrying capacity. These results demonstrate the substantial variations in load-bearing capacities among the beams and emphasise the efficiency of the strengthening application for RC beams in the constructions industry, particularly the use of iron-based smart memory alloy ribbed bars as strengthening materials.

Published: July 2024

FRP strengthening using near surface mounted (NSM)is recognized as a highly effective method for strengthening structures using FRP material. However, there are some drawbacks associated with this technique. One of the challenges is concrete cover separation failure, which leads to premature material failure and restricts NSM technique applicability. To address this issue, multinomial logistic regression (MLR) analysis is used. This analysis aimed to investigate the factors (Total Equivalent Steel Ratio TESR%, Stirrup Steel Ratio%, and presence of an anchorage) that can be used to predict the failure modes of reinforced concrete beams strengthened with the FRP-NSM system using a previously published dataset consisting of 131 beam tests from 25 studies. By using odds ratios, which are exponential coefficients, the MLR results were interpreted. The study indicated that a reduction in the TESR% predictor or increase in Stirrup Steel Ratio%, deceases the probability of conversion from concrete cover separation to other failure modes such as flexural failure, FRP bar debonding, and FRP bar rupture. Moreover, the reinforced concrete beams strengthened with the FRP-NSM system with anchorage has a positive contribution on the expected the failure modes: flexural failure, FRP bar debonding, and FRP bar rupture compared to concrete cover separation. Based on the classification table analysis, the model’s correct classification rate was 51.1%. The model is accurate in predicting failure modes, as its rate is higher than the chance accuracy rate of 36.4%.

POME is a biomass waste product from cooking oil in the food industry which requires well treatment before discharge to the main stream. It becomes problematic cause POME contains a lot of organic compounds, suspended solids, lipids, and others which is hazard. Proper treatment is necessary in order to avoid adverse effects on the aquatic and fresh water quality. As that concerned, FeCl3 was introduced to initiate the oxidation reaction and indirectly to degrade the organic compounds in the POME. Throughout the experiment, 0.005 M of FeCl3 solution was mixed into each untreated POME. Besides POME, Glucose and lignin has been used for comparative study. Since POME is biomass waste, UV-Vis Spectroscopy instrumentation is the best to characterize the degradation behavior of organic compounds contained in POME, as well as in glucose and lignin. Based on Lamda, λ Max, the absorbance value as the indicator to measure the degradation level. The experiment done in room temperature (±25 °C) and catalyst optimization was done by Cyclic Voltammetry, CV with potential window from -0.1 to 1.5 V and for UV-Vis spectroscopy, the wavelength(nm) range between 200-600 nm was set throughout the analysis.

This paper comprehensively investigates the dynamic viscoelastic behavior of shape memory polymer composites (SMPCs) reinforced with different weight percentages of kenaf fiber (KF) ranging from 0%, 5%, 10%, 15%, 20%, 30% and 40%. The dynamic mechanical behavior of these composites was characterized using dynamic mechanical analysis (DMA) over a range of temperatures. The objective was to determine the optimal fiber content of KF as reinforcement in SMPCs, specifically on viscoelastic response, storage modulus, loss modulus, damping and glass transition behaviour. The results revealed a clear correlation between the KF contents and the dynamic mechanical properties of SMPCs. The storage modulus significantly improves at higher KF content, particularly at elevated temperatures. Additionally, a quantitative assessment of coefficient C demonstrates strong interfacial bonding between fibers and the matrix in samples 30KF and 40KF. These samples also exhibit higher loss modulus and lower tan delta values, providing evidence for the efficacy of KF in enhancing composite properties. Moreover, higher KF contents induce a shift in the glass transition temperature, signifying enhanced in fiber-matrix interaction and thermal stability. The Cole-cole further demonstrates that at higher KF content, the sample surpasses Neat SMPU, presenting compelling evidence of improved matrix-fiber bonding. Statistical analysis through one-way analysis of variance (ANOVA) substantiates the statistical significance of the dynamic mechanical properties across the different weight percentages of KF-SMPCs. Based on these findings, 30KF is the optimal fiber content, balancing mechanical enhancement and feasible fabrication. This decision is grounded in challenges encountered at 40KF, where ensuring composite homogeneity becomes complex. This study contributes to the growing body of knowledge on utilization of natural fibers in development of advanced polymer composites while maintaining eco-sustainability.

Increasing population growth with high socio-economic development has changed the world landscape. These advancements have resulted to the water quality degradation and inadequate management of solid waste. In addressing these critical issues, a robust water treatment technology is required. Activated carbon (AC) in enhancing thewastewater effluent quality has proven to be a promising and sustainable solution. AC from sugarcane bagasse (SCB), empty fruit bunch (EFB), and rice husk (RH) have been identified as abundant bioresources in Malaysia. These materials possess unique compositions and potential for reuse. The production of AC involves both physical activation through a carbonization processat 600°C and chemical activation through impregnation with ZnCl2. In the study, samples from wastewater effluent were collected and analyzed for several parameters, including total suspended solids (TSS), chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammonia-nitrogen, nitrite-nitrogen, and nitrate-nitrogen. The samples have undergone treatment using activated carbon with various ratios. Here, the removal efficiency of pollutants was determined before and after the batch experiment. It can be denoted that AC, composed of SCB:EFB:RH in a ratio of 1.5:1:1, demonstrated an outstanding performance with an average percentage removal of 97%. Adetailed analysis of the physicochemical characteristics of the AC was conducted. The output revealed significant surface modifications and alterations in the functional groups of the AC due to the adsorption process. These findings set a remarkable implication for tertiary treatment in enhancing the quality of effluent and provides valuable insight into implementing sustainable practices in wastewater treatment operations.

The integration of Operational Modal Analysis (OMA) and Finite Element Model (FEM) techniques has proven to be a valuable approach for evaluating and maintaining the health of such structures. OMA extracts dynamic characteristics from a bridge's responses to ambient vibrations, while FEM employs computational models to simulate and compare these dynamic behaviours. This comprehensive methodology ensures an accurate representation of the bridge's behaviour and its correlation with real-world conditions. However, a significant challenge arises in assessing the Ultra High Performance Fiber Reinforced Concrete (UHPFRC) pedestrian bridge in Klang, Selangor, launched in October 2022, due to limited available information about OMA and FEM on UHPFRC. This research aims to develop FEM and conduct ambient vibration tests to obtain modal parameters. Moreover, the study investigates OMA techniques in the context of weak excitation sources, filling a critical knowledge gap. By comparing experimental results with FEM, this research provides insights into the feasibility and reliability of OMA under challenging environmental conditions. The principal results reveal significant percentage differences in natural frequencies between FEM and OMA, with the most notable disparities occurring in the first mode. Nevertheless, the mode shapes extracted from OMA closely resemble those from FEM. In conclusion, this research enhances the understanding of UHPFRC pedestrian bridge behaviour and modal analysis techniques.

Published: July 2024

Crop wild relative (CWR) species of the Sakhalin flora, as well as local cultivated species and varieties, represent a crucial source of plant genetic resources (PGR) on Russia's largest island. The purpose of the work was to inventory PGR of Sakhalin Island.

Species of wild relatives of fruit and berry, forage, vegetable, medicinal, and other crops of the Sakhalin region are of undeniable interest for their introduction into cultivation and for direct use in breeding. Due to the remoteness of most areas of Sakhalin, it is necessary to conduct a more detailed survey of the most demanded species from a breeding perspective in order to refine the distribution of these species, as well as to collect the most valuable genotypes.

As a results of the exploration, 186 herbarium specimens (over 220 herbarium sheets) were collected. For each collection site, a photo documentation was made with geographical coordinates indicated. The studied species are characterized by geographic diversity, ranging from Eurasian to Japanese-Chinese species. For the first time in the flora of Sakhalin, a species of dikuscha currant (Ribes dikuscha Fisch. ex Turcz.) has been discovered. Both wild and cultivated species of strawberries (Fragaria iinumae Makino, F. yezoensis Hara, F. × ananassa Duchesne, F. moschata (Duchesne) Weston) and Sakhalin raspberries (Rubus sachalinensis H. Lev.) were found, which exhibit wide intraspecific diversity and were sampled not only as herbarium specimens, but also for live plant studies. Five wild honeysuckle species were collected along with two species of kiwi (Actinidia arguta (Siebold & Zucc.) Planch. ex Miq., A. kolomikta (Maxim.) Maxim.); crimson glorywine (Vitis coignetiae Pulliat ex Planch.), etc. The collected PGR also included those used by humans as forage, vegetable, industrial, medicinal and flavoring species.

In 2023, field explorations of cultivated plants and their wild relatives were carried out in the regions of the Volga Upland, the western part of the Caspian Lowland and the Stavropol Upland with the aim of further replenishing seed and herbarium collections of VIR.

A total of 525 samples of CWR and cultivated plants were collected, including 200 are herbarium sheets, 323 seed samples of cultivated plants and CWR, and a couple of cuttings. The collected material encompasses 145 species, including 91 cultivars. Seeds of the cultivars were purchased at markets, in supermarket chains and from local residents. The following areas were examined in detail: the left bank of the Lower Volga (Peschany anabranch, Kigach anabranch, as well as the “Novaya Roshcha” protected area). In the Republic of Ingushetia the team collected samples of cherry plum, Caucasian pear, barberry, viburnum, Lonicera orientalis, sea buckthorn, raspberry, and Malus orientalis, which local residents use in their diet. Also, samples of spicy herbs such as savory, catnip, oregano, thyme, etc. were collected. Hops were sampled in the Tambov and Volgograd provinces, the Republics of Ingushetia, North Ossetia and Adygea, from abandoned household plots in Botanika village in Gulkevichi District (Krasnodar Territory). The exploration in vicinities of Derbent and of the wall of Naryn-Kala fortress in Derbent resulted in collecting a rare specimen of Secale sylvestre Host., which previously used to be a fairly common plant in the North Caucasus, but is very rare now. Vegetable crops were collected along the entire route of the collecting mission. It was not always possible to collect seeds, so a part of the material enriched the herbarium collection. The collected material reflects the use of a vast range of vegetable and spicy plant species by the local population.

Collecting missions help to understand which species are of primary importance for the conservation of natural processes, biodiversity and the maintenance of local ecosystems. The genetic diversity of a region is a key object of research for geneticists and plant breeders. Landraces of vegetable, cereal and other crops may have unique properties, such as adaptation to local climate conditions or disease resistance. Work on the mobilization and conservation of the plant genetic diversity is the basis for modern breeding and genetic research.

Heat exchangers with uniform heating ensure even heat distribution, improving heat transfer efficiency and lowering thermal stress. It contributes to increasing the effectiveness of solar energy conversion into thermal energy in solar collectors, improving system performance and sustainability. It is essential for enhancing performance in both home and industrial applications because of these advantages. An experimental investigation was conducted to study the natural convective flow between two isothermal concentric cylinders filled with porous media (silica sand) and equipped with annular fins attached to the inner cylinder. The fins varied in length (Hf = 3, 7, and 11 mm), and the radius ratios (Rr) between the cylinders were also considered during the study. This work examines and discusses the effects of independent characteristics, such as fin height (Hf), radius ratio (Rr), and Rayleigh number (Ra) from 10 to 500, on heat transfer outcomes. As the distance between the two cylinders expands, the average Nu remains relatively constant for low values of Ra. However, as Ra approaches 100, the average Nu increases. These values also rose when Rr decreased for the hot cylinder and vice versa for the cold cylinder. The average Nusselt number versus Ra was analyzed in graphical form to show the effect of the fin number on the average Nusselt number. The analysis includes a range of fin numbers. It is found that as the amount of fins increases from n = 12 to n = 23 and eventually to n = 45, there is a decrease in the average Nusselt number. The decrease in average Nusselt number can range from 19.2% to 26.6% for the same value of Ra.

Published: July 2024

The simultaneous advances in artificial neural networks and photonic integration technologies have spurred extensive research in optical computing and optical neural networks (ONNs). The potential to simultaneously exploit multiple physical dimensions of time, wavelength and space give ONNs the ability to achieve computing operations with high parallelism and large-data throughput. Different photonic multiplexing techniques based on these multiple degrees of freedom have enabled ONNs with large-scale interconnectivity and linear computing functions. Here, we review the recent advances of ONNs based on different approaches to photonic multiplexing, and present our outlook on key tech-nologies needed to further advance these photonic multiplexing/hybrid-multiplexing techniques of ONNs.

Published: July 2024

To demonstrate their contribution to society, guidance and counseling study programs in higher education must ensure that they meet the defined quality standards. One measure of this standard was the level of satisfaction among students with academic services. The objective of this study was to examine the level of student satisfaction with academic services provided by the study program. To achieve the objective, we utilized a survey method and administered the SERVQUAL-based Student Satisfaction Scale (SSS) to assess students' expectations and perceptions of academic services across five distinct dimensions. The respondents were undergraduate students enrolled in guidance and counseling program under the Education Science Department. We selected the students as respondents by using simple random sampling. Following data collection, we conducted descriptive and statistical analyses to assess variations in expectation and perception scores within and across academic years. The main findings were that students expressed satisfaction with teaching services but highlighted deficiencies in administration and facilities, underscoring the need for ongoing service improvements. Finally, the study highlighted the usefulness of utilizing SERVQUAL model as one of frameworks for assessing students’ satisfaction with academic services in study program.

In this study, it was aimed to investigate the piano lessons repertoire applied in the Music Education Departments based on the views of the teaching instructors. For this particular purpose, the qualitative method was utilized in the study and a case study in accordance with this method was used. The study group of the study consisted of 10 instructors who were assigned by the easily accessible sampling method and who conducted piano lessons from five different Music Education Departments. The data of the study were collected by using semi-structured interview technique, which is one of the interview technique types. As the data collection tool, a "piano lesson instructor interview form" developed by the researcher was utilized. The qualitative data obtained as a result of the interviews were analyzed using the content analysis technique in accordance with the descriptive analysis stages. In the light of the findings analyzed under eight themes in the study, it was concluded that the instructors considered various criteria for the students, repertoire and course while generating the repertoire they used in the piano lessons applied in the Music Education Departments; that they definitely considered the course achievements, chose the works that met the achievements as much as possible, and planned the course according to these achievements; that they included the works from each period and also the Turkish works in the repertoire they used in order for students to recognize each period, to have the necessary information about these periods, to apply the rendering styles of each period and to gain technical and musical achievements by recognizing the whole piano literature; that they included various etudes and exercise from different composers; that they failed to prefer the works of different genres such as atonal, impressionist and popular music from the contemporary period for various reasons; and that they encountered various problems while creating a repertoire and furthermore, the piano literature which had a wide range, should not be restricted to a common repertoire to be used in the Music Education Departments.

The collaborative research determined the basic obstacles and difficulties small-scale fisheries face to improve socio-economic quality and become more prosperous. The purpose was to explore the factors causing poverty despite providing aid and subsidies in the form of knowledge life skills and empowerment programs. Data were collected through in-depth interviews and focus group discussions on all phenomena and analyzed qualitatively. The results showed that the fishermen were lazy, resigned, apathetic, lacked initiative, irrational, and worked instinctively. Moreover, the attributes were identified as completely inconsistent with the efforts to improve the quality of life. In conclusion, without a rational work ethic, high discipline, hard work, material orientation, thrift, and savings, it is impossible to improve the quality of life.
