This study aims to analyze the financial performance of Indonesian Railway Company (PT KAI) before and after the COVID-19 spread to see whether the pandemic has any impact on its financial sustainability. The financial performance was assessed through the Altman Z-score Bankruptcy Prediction Model and some financial ratios such as liquidity, profitability, and leverage from 2019 to 2022. The discussion of the analysis employs trend analysis as it is done in one company. The performance from 2020 onward reflects the healthiness of PT KAI after the pandemic spread in Indonesia. The COVID-19 influences the financial performance of PT KAI, as indicated by the decrease in the Z-score in 2020. The performance then improves steadily in terms of profitability from 2021 to 2022. The increase in profitability is in line with the relaxation of people's mobility due to the success of vaccination in Indonesia. The results of the trend analysis applied in the PT KAI context may not be generalized to other companies. This study may give insight to the Ministry of State Owned Enterprises and the public at large regarding the financial healthiness of the monopolistic railway transportation company in Indonesia around the spread of the COVID-19 pandemic.

SCYTHIANS AND THE POPULATION OF THE LATE BRONZE— EARLY IRON AGE OF UKRAINE (Based on Craniological Materials)
Authors: Rudych T.
Published: January 2025

The issue of a possible anthropological link between the populations of the Scythian period and the Bronze Age on the territory of Ukraine in the light of new anthropological data is examined in the paper.
The population of Ukraine during the Scythian period, both in the steppe and forest-steppe zones, was anthropologically heterogeneous. The populations had different directions of the links with chronologically close series, as well as with groups from the territory of Ukraine from earlier periods.
Most of the steppe Scythian groups were morphologically and statistically distant from the population of Ukraine in the Bronze Age (with the Multi-band pottery culture, Zrubna and Bilozerska cultures), as well as from the population of pre-Scythian Ukraine, represented by the Chornogorivka culture which is associated with the historical Cimmerians.
Most of the steppe population of Scythia, both male and female, should be considered as later migrants from the East. Some steppe Scythian groups show parallels with Zrubna culture of the eastern region (Volga and Ural regions) which could also be linked to later migrations from eastern lands. Among the female series of steppe Scythians there are those that show the similarities with the series of the Multi-band pottery culture of Ukraine and Moldova on one hand, and with Zrubna culture of Ukraine on the other.
In the forest-steppe groups of the Scythian period the dominant anthropological links are directed to the western regions of Ukraine (Volhynia) from the Late Bronze Age. There are also anthropological analogies, although less pronounced, with the population of the Bilozerska culture, the Chornogoriv culture, and Zrubna cultures of both Ukraine and more easterly territories. Some forest-steppe groups have no analogies with earlier populations of Ukraine, and they can be linked to migrants from the Scythian period.
COUNT ALEKSEY UVAROV AS A RESEARCHER OF OLBIA AND ITS OUTSKIRTS
Authors: Kuzmishchev O. , Sapozhnykov I.
Published: January 2025

The paper is focused on the description of the visits of сount Aleksey Uvarov (1824—1884) to Olbia in 1848 and 1853. During the first visit, carried out as part of a scientific excursion to the Northwest Pontic coast, count Uvarov examined the ruins of Olbia and gathered information about the burial mounds excavated near it.
The article details his descriptions of the ruins of Olbia and the excavations of five burial mounds carried out before him in 1832—1844. Particular attention is paid to the finds from the burial mound excavated in 1842, including a golden mask, the only one found in Olbia. It was probably the burial of a member of the Sarmatian elite.
This information was published by him in the first volume of «Studies on the Antiquities of Southern Russia and the Black Sea Coast» (1851). In addition, thanks to the participation of a professional artist Moritz Webel (1821—1875) in the expedition, watercolors of Olbia’s views were painted. Also, on behalf of count Uvarov, two plans of Olbia and its surroundings were created, which are of important scientific interest. In 1853, count Uvarov excavated six burial mounds in the southern part of the Olbian necropolis, near Shiroka Balka, which had been looted before. In addition, several excavation areas were carried down in the lower city of Olbia, mainly in its southern part. Unfortunately, the information about these excavations is very limited. A separate subject is the exploration by count Uvarov in 1848 of the burial mound «Grave of Malaya Katarzha». This barrow is located on the top of the plateau formed by the shore of the Budak estuary and the Gulf of Shabalat, 2.5 km southwest of the village of Belenkoye (Shabalat) and 3.4 km northwest of the Black Sea. The participation of count Uvarov to the excavation of this particular, extant burial mound, is shown for the first time.

КОНСТРУКЦИИ С ДУБЛИРОВАНИЕМ ТОПИКА МЕСТОИМЕНИЕМ И КОНСТРУКЦИИ ТИПА «CONCERNING Х» КАК МАРКИРОВАНИЕ ТОПИКА
Authors: Хургес А.М.
Published: January 2025

В этой статье предлагается применить схему анализа маркеров топика, основанную на локусе маркирования (то есть схему, в которой позиция маркера может определяться либо относительно выражения топика, либо относительно всей конструкции), к стратегиям маркирования топика, обычно анализируемым отдельно от сегментного маркирования. Рассматриваются конструкции с дублированием топика местоимением и конструкции типа “concerning X”, различия между ними, а также проблемы, связанные с их анализом.

In this paper I argue that an approach based on the locus of marking (in which marking may be associated with the topic constituent it2024, self or with the entire construction) may be applied not only to dedicated topic markers, but to some other constructions typically analyzed separately, namely, to constructions where the topic constituent is doubled by a pronoun, and to constructions similar to the English “concerning X” construction. I describe the variation these types of constructions show (including the variation in how similar they are to clear segmental topic marking strategies) and the problems they pose for analysis.
EVALUATION OF STATISTICAL PROPERTIES OF ENCRYPTION RESULTS BASED ON INFORMATION-DRIVEN OPERATIONS
Authors: Rudnytskyi V. , Larin V. , Pidlasyi D.
Published: January 2025

The article evaluates the statistical properties of the results of encryption of pseudo-random sequences based on information-driven operations. The importance and significance of the use of pseudo-random sequences for optimizing the structural characteristics of systems (complexes, samples) of weapons and military equipment and their components are shown.
It is noted that the period of the pseudo-random sequence should be such that the final sequence of adequate length is periodic. Relatively short non-periodic subsequences should be as indistinguishable as possible from random sequences, in particular, meet various randomness criteria.
Based on the implemented software implementation of the information protection method, the generated pseudo-random sequences were tested using the NIST STS test software package. Analysis of the test results allowed us to conclude that the proposed method of cryptographic transformation based on information-driven operations is suitable for use in information resource protection systems.
The possibility of using various random initial states or entire sequences in the implementation of cryptographic transformations is considered. It is found that the stability of cryptographic transformation directly depends on the algorithm for generating random numbers and sequences, namely on their degree of randomness.
Pseudo-random sequence generators are the most important elements of any security system, the reliability of the latter is largely determined by the properties of the generators used. High-quality pseudo-random sequences, which are inherently deterministic, have almost all the properties of implementations of truly random processes and successfully replace them, since random sequences are extremely difficult to generate.

Authors: Trystan A. , Shulezhko A. , Berezhnyi A.
Published: January 2025

In the article considers the problem of building a swarm of unmanned aerial vehicles for signature formation during the testing of high-tech weapons and military equipment. The formation of accurate signatures is a critical task in the in the process of testing modern military systems, as it determines the effectiveness of their use in real- world conditions. In particular, it allows to assess the characteristics of weapons, optimise tactical algorithms for their algorithms for its use and ensure the reliability of control systems. The study proposes a methodology that combines modern approaches to modelling of unmanned aerial vehicles using artificial intelligence algorithms and decentralised intelligence algorithms and decentralised control systems. The proposed model takes into account the following key aspects: adaptability to external conditions, dynamic change of swarm parameters in real time and the ability to perform complex manoeuvres to achieve the specified parameters of signature formation. Particular attention is paid to synchronising the actions of unmanned aerial vehicles as part of a swarm, which ensures high accuracy of signature formation even in the face of interference and constraints caused by the environment. The methodology includes the analysis of functional and technical and technical characteristics of individual unmanned aerial vehicles and their interaction within the within the swarm. The algorithms of communication between the devices are described, based on the principles of self-organisation and cooperative decision-making. An important element of the study of the study is the development of models for predicting swarm behaviour in complex conditions, which can significantly increase the system's resistance to external disturbances. In the article presents simulation results that confirm the effectiveness of the of the proposed approach. In particular, the influence of different swarm configurations on the accuracy of signature formation, as well as the effectiveness of the application of decentralised control in comparison with centralised control. The main advantages of using a swarm of unmanned aerial vehicles for this task are identified, in particular, increasing the speed of task execution, reducing the cost of technical support, and increasing the reliability of the system as a whole. The results obtained have important practical implications for the development and improvement of methods for testing of military equipment, as well as the creation of innovative approaches to the management of swarms of unmanned aerial vehicles. In the future, the methodology can be adapted for other tasks, such as reconnaissance, patrolling, and rapid and rapid response to threats.
Russian Literature in Czech Catholic Periodicals of the 1920s (Magazine “Archa”)
Authors:   Institute of Slavic Studies of the Russian Academy of Sciences, Amelina Anna V.
Published: January 2025

The paper looks at the perception of Russian literature by the Czech Catholic magazine “Arсha” in the 1920s, when a high degree of politicization of culture contributed to the extreme ideological differentiation of periodicals, and at the same time to the reception of the work of Russian writers, which in turn often served as a means of ideological and political propaganda. In the literary magazine “Arсha”, which served as a platform for Moravian writers and critics, Catholicism was often identified with Christianity in general, that fact affected the perception of Russian literature, being assessed in the publications, on the one hand, from the point of view of the writers' attitude toward religion, and on the other hand - to the ideas of the Bolshevik revolution. When analyzing literary works, the magazine placed a strong emphasis on contrasting two cultures, Latin and Byzantine, but on the other hand, the value of the Christian community and the role played by Russian writers in the spread and strengthening of the true faith is undoubtedly recognized, sometimes even attempts are made to bring Russian culture closer to Catholicism. In addition, the moderate nationalism of the magazine’s authors forms an opposition between the Slavic and Germanic worlds on the pages of the magazine. This combination of opposition and at the same time the search for commonality for Czech and Russian cultures in the confessional and national fields makes the magazine “Arсha” a unique cultural phenomenon of the 1920s, which played a role in creating a positive image of Russian literature in the eyes of the Czech public.
The Metaphor “Jesus Christ - Sweetness” in the Choral Concerts of the East Slavic Baroque
Authors:   Pskov State University, Gerasimova Irina V.
Published: January 2025

The article analyzes the musical and poetic compositions of Baroque choral East Slavic concerts, including a "taste" metaphor - the naming of Jesus Christ as spiritual sweetness. The composers and singers of these concerts were mainly natives of the Kiev Metropolia. Choral works in which Jesus Christ is called "The Sweetest", "Sweetest", "All–sweet", "sweetness" in the refrain "About Mary, Mother of Sweetness" of the concert "Theotokos, the Most Holy Virgin Mary" and the concert "All is my Desire, all is Sweetness, Jesus!" were distributed in baroque parts for three-five voices from the last third of the XVIIth c. The article discusses by what artistic means this analogy is revealed in baroque choral concerts and what semantic shades are born in the interaction of musical and poetic texts. The assumption is put forward that the identified layer of compositions belongs to the Vilnian school of the partes concert of the second half of the XVIIth c. The analysis of the concerts showed a variety of interpretations of the metaphor of Christ the Savior, called sweetness. The sources for the creation of concert texts were well-known Orthodox prayers, Catholic Litany, Orthodox Akathist genre. The epithet "Sweetest" and other derivatives of the word "sweetness" were included in a number of epithets that make it possible to feel Jesus Christ with all the receptors of human perception, in this particular case, to taste spiritual sweetness. The epithet "sweetest" was used to characterize the third hypostasis of the Holy Trinity — the Holy Spirit, as one of the epithets of praise in the praise of the Lord, and, finally, as a basis for contrasting the sweet eternal life in Christ and the bitter life in the sinful world

Preimaginal stages of Areas galactina (Hoeven, 1840), a widespread tiger moth species of the Oriental region are described in this paper. The unique feature of the species is the presence of eight larval stages, whereas most of the subfamily Arctiinae have only six or seven of them. Additionally, the first records of Areas galactina are reported from four provinces of Laos: Phongsaly, Attopu, Champasak, and Sekong. The records from Attopu, Champasak, and Sekong provinces confirm the occurrence of this species in the south of Laos for the first time.
Finite Elementary Analysis of Electrical Performance for Glass Type Insulator Under the Inclination Effects
Authors: Su Ting Yan , Yaakob Shamshul Bahar , Mohd. Ariffen Amizah
Published: January 2025

This paper presents the modelling of a glass type of insulator with a voltage rating of 132 kV. The insulators play a critical role in transmission lines to ensure the stability and reliability of the system. Glass insulators are still widely used in overhead transmission systems because of their dielectric strength capability. Whenever faults occur in the transmission line or system, a considerable cost for maintenance and repair is required. The outdoor application of the insulator has resulted in exposure to various service conditions such as weather, pollution and lightning. Indeed, the inclination effect under the wind load is one of the significant challenges for outdoor insulators. Therefore, this paper studied the electrical performance of the 132 kV glass insulators under the inclination effects through Finite Elementary Modelling (FEM). In this simulation, the model of the glass insulator is constructed in four different inclination angles using the modelling software Ansys Maxwell 3D. From the results, the electric field distribution for the insulator became uneven when the insulator was inclined. With the reduction of clearance distance under inclination effects, the localised electric field form may increase the electrical discharge and arching likelihood. In a worst-case scenario, the flashover may cause faulty transmission equipment. In either case, the electrical performance of the insulator is reduced under the inclination effects.

Published: January 2025

Understanding Building Information Modelling (BIM) is not only a tool that visualization the concept of one’s design, but also a system that comprises the significant attributes throughout the entire building lifecycle including pre- and post-construction stages. Building undergoes the process of aging due to occupancy or environmental factors that affect the structural integrity. In Malaysia, non-destructive testing (NDT) for building condition assessment (BCA) often relies on visual inspections, overlooking the internal defects that could lead to structural failures if left untreated. To enhance the framework of the BIM integrated building’s health check, case studies on several industry examples that have employed different BCA approaches that can be linked to the digital twin to augment the visualization, improve efficiency in localizing the deterioration, and determine the geometrical extent of the concrete crack to assist in the maintenance decision-making process. This study aims to address these limitations by reviewing various NDTs and proposing a comprehensive, integrated approach combining conventional NDT with emerging trends like AI-driven methods and computing waveform analysis. This paper systematically evaluated the current methods using the benchmarks, including AI-assisted techniques, sensors, and stress wave analysis, to establish their efficiency, accuracy, and practical integration with digital twin technology. The findings emphasize that using a three-dimensional crack mapping model incorporating computing technology and machine learning to refine the result can more accurately identify areas of concrete deterioration, leading to better maintenance decisions. The key result from this paper paved the foundation for the development of an integrated three-dimensional (3D) crack mapping model to detect deterioration not only from the surface of the building’s element but also thoroughly and accurately identify the damage to the building to prevent catastrophic structural failure.

Subgrade materials are primarily defined by their capacity for sustained deformation under stress, which serves as an indicator of their strength or stiffness. The infiltration of rainwater into damaged pavement will have an impact on the performance of the subgrade. Submerging the subgrade in floodwater causes water to penetrate the subgrade pores, resulting in an increase in the subgrade's weight. This research aims to examine the effects of marble dust and coconut shell as additions to subgrade materials and further investigate the potential of utilising this hazardous waste to enhance the strength of the soil. This study investigates the hydraulic properties of the soil around the Universiti Pertahanan Nasional Malaysia (UPNM) campus, considering the addition of waste marble dust (MD) and crushed coconut shell (CS). The following ratio mixes of marble dust and coconut shell in this research are: MC1 (5:2.5), MC2 (10:2), MC3 (15:1.5), MC4 (20:1.0), MC5 (25:0.5), and a control sample without any additive. Laboratory experiments were conducted on the soil mixtures, which included sieve analysis, constant head pressure, and pressure plate extractor testing. The findings of the study indicate that the mixed-design MC1, consisting of 5% MD and 2.5% CS, demonstrates the most efficacy in improving the hydraulic properties of the subgrade. The primary focus of the Green Technology Master Plan Malaysia 2017–2030 is to enhance resilience to climate change and disasters by prioritising environmental sustainability. This is particularly highlighted in Chapter 6, which focuses on waste management.

Plastic waste poses a major environmental challenge in Southeast Asia, with Malaysia as the largest contributor. Recycling offers a solution by incorporating plastic waste as a substitute material in concrete production. This approach addresses environmental concerns while promoting sustainable construction practices. This study investigates the optimal ratios of cement, water, plastic replacement, and aggregate in concrete compositions. Furthermore, it examines the influence of domestically sourced waste plastic on concrete properties. A comparative analysis is conducted between concretes with and without plastic replacement, focusing on fine and coarse aggregates. Polyethylene terephthalate (PET) plastic is utilized at replacement levels of 10% and 20% in both fine and coarse aggregates. The appropriate concrete aggregate ratio is determined based on recommendations by the Department of Environment. Various tests, including slump, density for hardened concrete, water absorption, and compressive strength, are performed to assess concrete workability. The results indicate that the density of coarse aggregate plastic concretes (DP10C, DP20C) exceeds that of fine aggregate plastic concretes (DP10F, DP20F). Additionally, coarse aggregate plastic concretes (DP10C) exhibit lower water absorption rates compared to fine aggregate concretes (DP10F) at both 7-day and 28-day curing periods. Compressive strength testing reveals that concrete replacement with coarse aggregate (DP20C) yields higher strength compared to fine aggregate (DP20F). However, the replacement of fine aggregate is limited to 10%, as exceeding this percentage drastically reduces concrete strength. In conclusion, the incorporation of plastic waste in concrete production demonstrates positive environmental effects and aligns with the concept of sustainable concrete, thereby contributing to environmental conservation efforts.

In contemporary times, there is a growing inclination within the construction industry to advance sustainable and eco-friendly concrete production by making use of recycled components. The proliferation of glass products has led to a substantial accumulation of glass waste, posing environmental and human health concerns. This research presents the effects of glass waste on the strength and sound absorption properties of glass waste into foam concrete (GW-FC) for wall application. The main objective is determining the optimal ratio of Glass Waste to reinforce Foam Concrete (GW-FC) suitable for wall application purposes. The methodological approach various ratios of glass waste 0%, 5%, 10%, 15%, and 20% mixed with 3% of foaming agents. The glass waste is mixed with 50% cement, 30% quartz sand, and 20% water to yield a slurry concrete mixture poured into molds for 7 days, resulting in solidified cake-like concrete. After the curing process, the cake is transformed into Glass Waste into Foam Concrete (GW-FC) designed for wall applications. The results show increasing strength when adding the composition of glass waste with a 20% GW-FC ratio stands out, exhibiting optimal outcomes achieving the highest tensile strength of 5.8 MPa and the maximum Young's Modulus at 67.34 MPa, while for the lower tensile strength 0% GW-FC at 1.12 MPa. The 20% GW-FC composition attains acceptable density at 0.013 g/cm³ and a porosity of 83%. The. For sound absorption, the 20% GW-FC is the most significant Sound Absorption Coefficient (SAC) at 0.6 α when assessed at a frequency of 5000 Hz, denoting strong sound-absorbing capabilities. GW-FC with a 20% GW incorporation level yields the most capable outcomes concerning physical and mechanical attributes for applications involving walls.

This paper presents the experimental solutions for the influence of length to the behavior and settlement performance of stone column. Laboratory experiments were conducted to compare the results between the settlement performance of end bearing stone columns and floating stone columns. Unit cell concept is used to idealize the settlement performance of large column group under the uniform load. The parameters that investigated are the column length to diameter ratio. This experimental investigation used a small-scale unit cell model tank and investigated the column length of a single column. Furthermore, the physical test involved the use of a custom-made stone column model, constructed with a rectangular steel frame measuring 600 mm in height and 260*260 mm in length and width. The experiment incorporated three different column heights: 400 mm, 320 mm, and 240 mm. Additionally, three distinct area replacement ratios of 33%, 23% and 15% were employed in these testing experiments. The results indicated that an increase in the length of stone columns correlates with a reduction in settlement, together with the increase ability to dissipate excess water pressure leading to a faster consolidation rate. The settlement performance was compared with existing analytical solution where reasonable agreement was obtained.

Malaysia's industrial sector generates a lot of non-biodegradable solid waste. By products of industrialisation including plastic bags, PET bottles, and pulverised waste LDPE, coir must be disposed of. Reusing waste helps reduce pollution, and conserve non-renewable resources. However, the use of LDPE in mortar mixes as a partial replacement for sand adversely affects the compressive strength. In order to mitigate this issue, steel fibre was included as an addition. This study examined the use of LDPE recyclable plastic bags in cement mortar to determine the best proportion of LDPE to steel fibre. The study replaced 0% to 15% of fine aggregates in mortar mixes with LDPE, increasing by 5%. The mortar's density, compressive, and flexural strengths were measured at 7, 14, and 28 days. The experiment indicated that adding 15% of LDPE to cement mortar decreased density (1736 kg/m3), compressive strength (21.61 MPa), and flexural strength (3.562 MPa). From this, it can be concluding that 5% LDPE and 2% steel fiber are the optimum percentage that can be use in the future study.

The simulated isolator consisted of a constant area (25 mm by 30 mm) rectangular duct back-pressured by a triangular-shaped wedge with a vertex angle of 60 degrees. The CFD technique is used to investigate the performance of converging-diverging (CD) nozzles at different divergence angles ranging between 5° to13.5° with constant throat diameter and the isolator. The dimensions of the CD nozzle considered were 25.9 mm and 7.7 mm inlet and throat diameters, respectively, and nozzle pressure ratio (NPR) of 9. The study aims to isolate the shock wave inside the isolator so that fuel injection can be done at a supersonic Mach number. The 3D model is created on Inventor 2022 software, with a converging angle of 20° and a converging length of 25 mm. The results showed that the diverging angle is crucial in determining the back pressure and Mach number. An increase of diverging angle by 0.1° causes flow separation at the lip of the nozzle. Thus, the optimum diverging angle of 13.5° achieves maximum velocity for a given CD nozzle geometry at specific operating conditions.

This research investigates the effectiveness of composite coatings in preventing corrosion in petroleum pipelines, focusing on computational methods for thermal and structural analysis. A 3-meter section of a Basra, Iraq pipeline was selected for evaluation. The study begins by establishing a baseline with an uncoated pipeline, followed by applying composite coatings both internally and externally. Finite Element Analysis (FEA) is used to assess structural integrity under high pressure and to perform a detailed numerical heat transfer analysis over a 15-year operational period. The thermal analysis evaluates the temperature distribution and thermal stresses that contribute to coating degradation and pipeline failure. By integrating Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE), this study demonstrates the critical role of advanced computational tools in modeling heat transfer phenomena and enhancing pipeline safety and durability. The findings provide actionable insights for optimizing coating technologies with a focus on thermal performance in real-world applications.

Glagah Linggah Forest Farmer Group is a farmer group that was given the trust by the Manikliyu traditional village to manage Glagah Linggah Pine Tourism. So far, they have received assistance from various companies, one of which is PT Tirta Investama, one of the industrial partners of the International Business Management study program. In the coaching conducted by PT Tirta Investama, there were several problems faced and they needed help from the campus in training digital marketing, operations, and communication design in serving international guests. Because so far when there are international guests, officers are less able to communicate. In addition, in terms of operational management, to welcome international guests and explain the facilities are also still limited, so it requires service excellence training. Facilities for bilingual and digital information are also limited. Marketing advertisements, mostly in Indonesia, have not penetrated marketing for international guests. So that this Community Service will later collaborate with PT Tirta Investama, where the campus will conduct training on how to welcome guests through service excellence and create some marketing content; communication design is expected to help smooth the operation of this Glagah Linggah pine forest tour. With this Community Service, it is hoped that this forest tour can develop its marketing more broadly to the international market supported by the service capabilities of officers and visual communication that is more supportive for international guests.

Ensuring good audit quality has become germane in recent times following developments that have ridiculed the credibility of financial statements all over the world.  Achieving a strong audit quality entails an auditor identifying and reporting pertinent abnormalities in corporate financial reports, demonstrating his expertise as a professional auditor. Audit quality remains fundamental in giving credibility to information presented in ?nancial statements. Reduced audit quality behavior remains a serious area of accounting and auditing literature and this can be ascribed to the importance of quality audits in a global business environment. This study is aimed at ascertaining the determinants of Dysfunctional audit behaviors. One hundred duplicates of organized questionnaires were given to selected accountants in the South-South region of Nigeria. This study employed a multivariate regression technique to analyze data collected from respondents. The results showed that auditor tenure and organizational commitment are inversely proportionate to dysfunctional behavior. The result further showed Task complexity and Time Budget Pressure are directly proportionate with dysfunctional behavior. This study recommended that commitment to audit should be tested periodically and should be used as the basis for retention. This study further recommended that elongated auditor tenure should be encouraged

Secondary School Learners’ Transition to the University: A Qualitative Research Approach
Authors: Tshisikhawe Mbulaheni Paul , Dube Buyisani
Published: January 2025

The transition of learners from secondary school to university education, while inevitable, has always been marred by myriad uncertainties and challenges. This is especially so for secondary school learners who register in previously disadvantaged higher education institutions. The purpose of this study was to explore the challenges experienced by first-year learners who transition from secondary school to university. The study followed a post-positivist methodological stance. A phenomenological design of the qualitative research approach was used in this research. The study adopted a purposive sampling technique to select two lecturers and ten first-year learners, who were interviewed using face-to-face and focus group interviews. The sample was drawn from the lecturers who taught first-year modules and all first-year learners in the school of education. Data was analysed and interpreted thematically. The study findings showed that challenges related to the orientation of learners, class attendance, language of teaching and learner support compromise the transition of first-year learners, a majority of who end up failing or dropping out of the university. This implies that learner integration and academic growth require supportive interaction with all stakeholders and the provision of resources and facilities. The study concludes that learners should be adequately prepared for the transition from secondary to university to enable them to cope with the social and academic demands of university life. The study has shown that the assumptions of Maslow’s hierarchy of needs theory can profitably be infused in learner transition thinking and practices to yield a successful university life.
