DIJAGNOSTIKA ZEMLjOSPOJEVA NA NADZEMNIM VODOVIMA ANALIZOM MAGNETNOG POLJA
Authors:   Electrodistibution of Serbia, Živadinović Goran
Published: December 2023

The paper analyzes the components of the magnetic field of a three-phase overhead line at an arbitrary point on pole, where a device for detecting and diagnosing a earth-fault is usually placed. The work shows that by measuring the horizontal and vertical components of the magnetic field at some point on the pole under the conductor of the overhead line, it is possible to detect and diagnose not only the occurrence of a fault in the overhead network, but also the type of fault. Phase currents of an overhead line with an earth fault are calculated without using symmetrical components, but by writing Kirchhoff's rules for voltages and currents in a three-phase network. It is shown that the criterion for recognizing the type of failure, in addition to the increase and decrease of the magnetic field components, can also be the quotient of the vertical and horizontal components of the field, ⁄ The quotient modulus | ⁄ | and the phase angle ( ⁄ ) can be used to diagnose and determine the type of failure. A general mathematical model and a numerical example on a specific line on which the author installed devices, are given.

The integration of renewable energy sources brings significant changes in power systems. Considering that there is a huge number of requests for the analysis of the impact of the connection of wind farms to the transmission network of Serbia, the analysis of the possible effects of wind farms on the voltage conditions in the transmission network is of particular importance. Due to their variability and different geographical distribution, they affect various aspects and parameters of the network, among which is the effective value of the operating voltage. When examining the impact of wind farm integration on critical regimes in terms of voltage conditions in the transmission network, the practice is to observe regimes in which generators have maximum active power generation, while consumption in the network is minimal. It will be shown that this is not always the case, but sometimes the maximum operating voltages occur in modes when the generation of active power of wind power plants is not maximum, and it is necessary to take other influential factors into account when analyzing those operating modes.

The porcelain capand pin insulator is composed of a bell-shaped or disc- shaped insulating part and metal connecting parts. The segment of the insulating part of the porcelain cap insulator located between the two metal ends for connecting the porcelain cap insulators is subject to much higher electrical stress than the rest of the insulating part. These insulators are class B by construction, which means that the distance between the two metal ends to be joined is less than half of the jump distance. For the construction of cap porcelain insulators, it is characteristic that most failures are caused by the occurrence of a breakdown, that is, a destructive discharge through the solid insulating material of the insulator, which causes a constant loss of dielectric strength. This paper presents tests in accordance with relevant standards supported by results, as well as field tests that represent a practical way for users to detect a breakthrough in a timely manner.

This paper presents a practical problem of connecting the new solar power plant with maximum capacity of 150 MW in the southern part of Bosnia and Herzegovina to the existing 110 kV transmission line Trebinje - Komolac, whose conducor Al/Fe is with cross-section 150/50 mm2 . This transmission line does not have enough capacity for the new solar power plant connection. The conventional solution of the problem would be replacing conductor by new one with larger cross-section and ampacity. The use of new conductors with larger dimensions would cause an increase in the mechanical stress of the existing poles and the replacement of the poles would be necessary. In order to increase the transmission capacity of transmission lines without increasing the mechanical stress, new materials and constructions of conductors have been developed. In this paper, a solution to increase the transmission capacity of the monitored transmission line by replacing the existing Al/Fe conductor with a special HTLS ("High Temperature Low Sag") conductor is proposed. For this purpose, power flow and conditions in the network were analyzed when using Al/Fe and HTLS conductor on the monitored transmission line, and the obtained results were compared.

— Flashover on the insulation, as a result of the pollutants deposition present in the air on the surface of the insulator, has significant consequences on the reliability and safety of the power system due to its direct impact on the reduction of the availability of high-voltage electrical equipment that contains insulators for external installation. Although the occurrence of fault as a consequence of pollution is a known phenomenon since the beginning of electricity transmission, it has gained importance in recent decades with the increased scope of industrial development and more intensive cultivation and treatment of agricultural land. In this paper, the influence of the most common salt mixture present in agricultural fertilizers (NaCl, K2SO4, NaHCO3, CaSO4, KHCO3, MgSO4, NH42Fe(SO4)2x6H2O, iron ammonium sulphate, dust and urea) on the withstand voltages and the risk of flashover on cap and pin type insulator has been considered. The presented results show that soluble salts as well as solid insoluble deposits significantly affect the withstand voltages reduction of insulators, especially in the case of thicker solid insoluble deposits. Based on these results and the classification of the degree of pollution in accordance with the IEC 60815-1 standard, conclusions were drawn and guidelines were given for the dimensioning of insulation in the phase of developing projects for high-voltage transmission lines with the aim of achieving reliable behaviour of this electrical equipment in operational conditions with increased agricultural pollution.

Published: December 2023

The land mafia has undermined the legal order in Indonesia, not only at the level of investigations, but also at the end of the judicial system. Conflicts between the land mafia and the people often become conflicts between the strong and the weak. The rise of the land mafia shows that land is a high and promising economic investment community that attracts interest in owning and controlling it in various ways, resulting in lawlessness, disputes, and conflicts in the land sector. These land mafias have a variety of modes that can be used to be able to take over land owned by others. The eradication of the land mafia in Indonesia has been specially instructed by the President of the Republic of Indonesia Joko Widodo by deploying law enforcement officials and the Attorney General's Office to prevent the eradication of the land mafia in Indonesia. This research discusses law enforcement in the eradication of the land mafia in Indonesia and discusses the legal protection of Notaries /PPAT in the case of land mafia in Indonesia. This research is a normative juridical research using a statutory approach, a concept approach, and an analytical approach. Data collection techniques are obtained by means of literature research and data analysis using descriptive qualitative analysis. The establishment of the Anti-Land Mafia Task Force aims to eradicate criminal practices indicated by the land mafia and the modus mosud of the land mafia. The modes of the land mafia are very diverse such as falsifying data, entering the yards of houses without rights, taking away the property rights of others, etc. Law enforcement in the eradication of the land mafia should be a priority for the Government. The establishment of the Anti-Land Mafia Task Force is an instruction from the President of the Republic of Indonesia Joko Widodo, but the President who is the head of state should not only instruct but the President must also evaluate the performance of the Anti-Land Mafia Task Force. Notaries/PPAT do not have duties and obligations in eradicating the land mafia because Notaries/PPAT there are general officials and state officials who have the obligation to make an authentic deed. Notaries/PPAT need to protect themselves and their profession from land mafia cases. Notaries/PPAT need to apply the principles of accuracy and prudence in making authentic deeds. The principles of accuracy and prudence used by Notaries / PPAT are able to minimize the crime rate of the land mafia in Indonesia.

Road infrastructure is a vital component in fostering economic growth and human mobility. Well-maintained and safe roads enhance transportation effectiveness and efficiency. However, in reality, several road segments fall short of stringent standards, both in terms of suitability and safety. The road sections A.H. Nasution (Medan) and Ngumban Surbakti (Medan) have never undergone prior fitness assessments. Thus, this study aims to establish a ranking to determine their fitness levels. This research assesses the suitability of A.H. Nasution (Medan) and Ngumban Surbakti (Medan) roads using the Analytical Hierarchy Process (AHP) and the Multi-Attribute Utility Theory (MAUT) methods. The collected data is processed and analyzed using both AHP and MAUT methods to determine the relative weights of factors influencing road suitability. The AHP method, when applied to respondent data, revealed the highest weights for road geometric technical aspects, scoring 3,36 for A.H. Nasution and 3.04 for Ngumban Surbakti. Conversely, the lowest weights were assigned to road equipment technical aspects, with 0,592 for A.H. Nasution, and road section utilization, with 0,3 for Ngumban Surbakti. When employing the MAUT method, the highest weights were attributed to complementary road structure, scoring 1,265 for A.H. Nasution and 1,140 for Ngumban Surbakti, whereas the lowest weights pertained to road section utilization, with 0,04 for A.H. Nasution and 0,413 for Ngumban Surbakti. In future research, it is advisable to conduct a comparative study between AHP and MAUT in scenarios with a higher number of criteria or increased complexity. This may also explore the potential development of new methods that integrate the strengths of both approaches to address these issues.

Authors: Kipleting Rugut Cornelius , Kisilu Syomwene Ann
Published: December 2023

The vision for university education in Kenya is to provide globally competitive quality research and training. The aim is to produce highly trained researchers who can contribute significantly to the country’s national and economic development. However, several studies show that there are a number of supervision shortfalls in universities in Kenya; and this presents a great concern in the training of research students. The aim of this study therefore was to explore the perspectives of postgraduate students and supervisors on how postgraduate supervision can be strengthened in universities in Kenya. This was a qualitative study located within a social constructivist paradigm. Convenient and purposive sampling was utilised to select 18 participants from three public universities in Kenya. The participants were academic supervisors and postgraduate students doing Masters and Doctoral studies. Data collection was done using unstructured individual interviews with supervisors and focus group discussions with students. The data generated was analysed thematically and Vygotsky’s social-cultural theory was used to make meaning of the findings. The results revealed that supervisors need to be supported through capacity-building programs that shape their knowledge and skills and building physical and online structures that support the supervision process. It also revealed that there is a need to engage students in a comprehensive mentorship program and a constructive student-supervisor relationship. The study recommends that for the achievement of effective postgraduate supervision, there is a need for universities in Kenya to invest in developing the skills and knowledge of supervisors and improve the supervision environment by setting up the necessary support structures. Student–centered programs should also be put in place to enable students’ active participation and positive social interaction between the student and the supervisor.

THE "IMPORTANT VIEWPOINTS" OF G.S XI JINPING ON CHINESE EDUCATIONAL REFORM AND DEVELOPMENT: LESSONS FOR AFRICAN EDUCATION
Authors: Degreume D.
Published: December 2023

China has made significant investments in education since its reform and opening up. Today, China not only has the best education system in the world but also high-quality education, which is an excellent model for other countries, particularly African countries. As the country's leader and first actor, China's General Secretary Xi Jinping has delivered an unbroken stream of encouraging speeches in support of the country's long-term development and modernization of education. In his 2018 speech, Xi Jinping underlined the need to understand the "Nine-persistence" of education reform and development. It is obvious that Africa must take note of President Xi Jinping's significant remarks on the reform and growth of education in order to better the education system on the continent as China's first economic partner and closest ally. What may therefore be learned about Chinese education from General Secretary Xi Jinping's "Nine-persistence"? By making use of pertinent sources, this study attempted to provide an answer.

INCLUSIVE EDUCATION AND POLICY IMPLEMENTATION IN NIGERIA: AN IMPLICATION FOR EDUCATIONAL DEVELOPMENT IN THE 21ST CENTURY
Authors: Orlunga Bartholomew Godstime , Alikor Oroma
Published: December 2023

Even though it is a clear fact that inclusive education as a policy is stated in Nigeria’s national policy on education, our point of interest is centered on its practicability. This is because the issue of policy implementation is virtually in every policy outline in Nigeria up to this day. Inclusive education which is aimed at integrating persons with special needs and those without any form of impairment to learn side by side in the same classroom environment has failed largely in its regards, especially at its implementation stage, which is a result of the unperturbed nature of both government and other state actors who are piloting the affairs of the country. Certain constraints relating to corruption, lack of proper sensitization, inadequate educational facilities, location of institutions, etc. were some factors considered in this work as responsible for the failure of educational development in the 21st century in Nigeria. Hence, the workability of inclusive education now rests in the hands of every meaningful Nigerian. Those with questionable characters must not be involved in any policy-making process and the government must streamline approaches on how its policies will be attended to at all levels.

ACADEMIC ENJOYMENT AND PROFICIENCY IN ENGLISH: THE MEDIATING ROLE OF ORGANIZATIONAL STRATEGIES BY SECONDARY SCHOOL STUDENTS IN CHINA
Authors: Jiang Meihong
Published: December 2023

Previous studies have extensively explored the mediating mechanisms between academic enjoyment and achievement. However, few studies have examined the mediating effect of cognitive strategies between these two constructs, especially in teaching English as a foreign language (EFL). This research aimed to investigate whether foreign language organizational strategies (FLOS) mediate the association between foreign language enjoyment (FLE) and foreign language proficiency (FLP). Five hundred and twenty-four Chinese secondary EFL learners aged 11 to 15 participated in the questionnaire survey. Structural equation modelling (SEM) and mediation analysis results showed that FLE could affect FLP directly and indirectly through FLOS after controlling for gender and age. Also, it was found that FLOS partially mediated the association between FLE and FLP. This research deepened the understanding of the mediating mechanisms between FLE and FLP. Implications, deficiencies, and suggestions for future research are discussed.

TEACHING PHOTOSYNTHESIS USING AN INQUIRY-BASED APPROACH VIA A DIGITAL EDUCATIONAL PLATFORM TO PROMOTE STUDENTS’ UNDERSTANDING
Authors: Fermani Maria , Georgiou Martha
Published: December 2023

Our research aimed to identify whether inquiry-based learning via Go-LAB platform, could enhance students learning about photosynthesis. The study sample consisted of 92 second-year high-school students, and the educational intervention consisted of three teaching hours. We conducted a pre- and a post- test via a questionnaire with closed-ended questions to detect the possible results of our teaching intervention. The statistically significant difference between the pre- and post-test surveys indicated that the inquiry-based intervention via Go-LAB platform helped students to better understand the concept of photosynthesis. At the same time, positive learning effects in our study were found to be gender-independent, a finding that is in line with a multitude of studies. Students gave more correct answers about the photosynthesis process, and several alternative ideas seemed to be overturned. Consequently, according to our findings, inquiry-based learning supported by the Go-LAB platform seems to represent an efficient way of teaching complex biological concepts like photosynthesis.

POTENTIALS OF INTERCULTURAL COMPETENCE IN PROMOTING CRITICAL THINKING IN THAI TERTIARY EDUCATION
Authors: Namsaeng Pasara , Ambele Eric A.
Published: December 2023

Intercultural competence is a contemporary pedagogy in Thai tertiary education. The current study aims to explore the potentials of employing intercultural competence to promote critical thinking in Thai tertiary education. There are two constructs being reviewed: intercultural competence and critical thinking. The origin and benefits of intercultural competence are first discussed, followed by its frameworks. Then the challenges of teaching intercultural competence in Thai tertiary education are raised, followed by general knowledge of critical thinking. After that, the interconnection between intercultural competence and critical thinking is provided as a claim of the potentials of intercultural competence in enhancing critical thinking. This academic article proposes that there are five reasons why intercultural competence potentially enhances critical thinking. First, its matching characteristics of ‘holistic’ and ‘judiciousness’ in culture and critical thinking’s frameworks. Second, the shared characteristic of both constructs is that they are learnable through inquisitive, truth-seeking, and analytical skills. Third, the open-mindedness of CT skills as a dynamic process of thinking. Fourth, the confidence in reasoning towards ethnocentrism with high determination. Finally, the aforementioned aspects are mutually and systematically supportive of one another. With all these elements, there is high potential for using intercultural competence instruction to promote critical thinking in tertiary students.

SELF-INVESTIGATION INTO REPERCUSSIONS OF PERFECTIONIST BEHAVIOR ON ACADEMIC ANXIETY AND FLEXIBILITY AMONGST CHINESE POSTGRADUATES
Authors: Wei Li-Wei
Published: December 2023

Within the sphere of educational psychology, the impact of perfectionism on academic anxiety and flexibility has been closely examined, especially in the context of Chinese postgraduates. The current study analyzed these phenomena within a cohort of 218 postgraduates from a private international Chinese college in Thailand, reflecting an amalgam of Eastern academic culture and postgraduate educational expectations. Results indicated a notable degree of academic anxiety (X=3.70, SD=.75), alongside moderate levels of flexibility (X=2.94, SD=.84) and perfectionist behavior (X=3.23, SD=1.01). Disaggregating data by educational level, Masters students presented with moderate anxiety (X=3.38, SD=.87), low flexibility (X=2.53, SD=.74), and low perfectionism (X=2.74, SD=.66), whereas Ph.D. students exhibited significantly higher anxiety and perfectionism (X=4.51 and X=4.48, SD=.84 respectively), yet demonstrated greater flexibility (X=3.99, SD=.71). Gender and profession proved to be insubstantial factors in influencing these constructs. Contrastingly, educational level was a potent differentiator, with significant disparities evident. The interrelations highlighted a negative correlation between academic anxiety and flexibility (r=-.121), but a positive correlation between academic anxiety and perfectionist tendencies (r=.424). Flexibility and perfectionist behavior were also positively correlated (r=.153). To mitigate the adverse impacts of perfectionism, the study advocates for cognitive-behavioral interventions to reshape perfectionist thought patterns and bolster adaptive coping strategies. It encourages cultivating an educational ethos that emphasizes learning and psychological welfare over impeccable achievement and suggests normalizing mental health discourse within academic environments to alleviate the stigma surrounding perfectionism and anxiety.
