The study explained the impact of government spending on economic growth in Libya. Public spending is one of the tools of financial policy, where the government spends, to achieve its economic and social objectives. Public spending in Islam aims to advance production, increase investment, and its regulation of production allows more investments. The Libyan economy achieved a financial surplus in the period from 2000-2012 AD through measures taken by Libya in economic legislation in order to reduce the burdens on the public budget, and the Islamic economy treated public spending by adhering to the principle of moderation in every type of consumer spending, the investment, and the honest. It is possible to provide the necessary resources to carry out other types, to achieve the interests of the spenders and the deserving alike. Islam, and government spending raises growth rates in the gross domestic product, and addresses the imbalance in economic cycles. The Libyan economy works on government spending to enhance economic growth. This study recommended working to reduce dependence on the oil sector creating other alternative sources of local income by supporting economic sectors and increasing investment spending.

Authors: Letaru Prudence Butele
Published: January 2023

Introduction and problem: Adolescent pregnancy is a public health concern in both developed and developing countries. Globally, it affects more than 16 million girls and young women .It is estimated that about 11% of births worldwide are to adolescents aged 15-19 years, more than 90% of which occur in low and middle income countries (WHO, 2014). Adolescent pregnancy is a concern in Uganda despite the endless efforts put in place by Ministry of Health and the other health stakeholders to reduce and stop it. This study focused on assessing factors contributing to adolescent pregnancy in Pajulu Sub-county, Arua district. Objectives: To assess the health service related, individual, and social cultural factors contributing to the prevalence of adolescent pregnancy in Pajulu Sub-county, Arua district. Methodology: The study employed a descriptive cross-sectional research design involving both qualitative and quantitative approaches. It was conducted in Pajulu Sub-county, Arua district, West Nile region among adolescent girls, adolescent mothers and pregnant adolescents aged between 12 to 19 years, and some key informants in the community. Results: The prevalence of teenage pregnancy in Pajulu Sub County was found to be 22.7%. Negative attitude of the health workers, lack of adolescent specific S/RH services, contraceptive nonuse, peer pressure, alcohol, cultural norms, family neglect, adolescent’s education level, and adolescent’s poor social status were found to be significantly associated with adolescent pregnancy. Conclusions and recommendations: The relatively high prevalence of adolescent pregnancy and the factors contributing to it pose a task for all stakeholders in the communities and nationwide to work towards addressing the problem. Therefore parents, community members, schools, and health workers are recommended to adopt a culture of discussing sexual and reproductive health issues, advocating for abstinence and where necessary, contraception be made open and accepted without stigma.

This study aims to contribute to the body of knowledge by using social identity theory to investigate the function of shared leadership in teams. The study examines the impact shared leadership can have on creative work behavior. In addition, the study used positive social motivation as a mediator and moderating role of preparedness. In addition, the study suggests a change preparedness as a buffer for improving innovative work behavior among workers of information systems as a result of shared leadership. The material for this study came from the completion of questionnaires by 236 different people working in Pakistani information systems. The data-gathering process involved using a convenience sampling method, which is not a random sampling approach. The sample size was established using G*Power (Hair et al, 2014). To evaluate both direct and indirect impacts, the Model 4 specification of the process macros created by Hayes was employed. On the other hand, the Model 1 specification was applied to test the moderation hypothesis. For this study, the individuals working for information system firms served as the unit of analysis. According to the findings, shared leadership has a useful link that contributes positively to innovative workplace behavior. It was also determined that the willingness for change has a moderating function in the relationship between shared leadership and pro-social drive.

Published: January 2023

Beta-casein (β-CN) is a major dairy protein subject to preferential degradation during storage. Our study aimed to isolate β-casein from bovine milk under dissociative conditions by the electrophoretic technique using Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE) and optimize an immunochemical technique such as Mancini radial immunodiffusion in order to monitor the evolution of this milk protein during storage. For this purpose, a series of physicochemical and bacteriological analyses revealed conformity with international standards. This allowed us to use quality milk for more detailed studies of proteins, in particular β-casein, which was selected as a marker of milk protein quality. The total casein of mixed milk samples was isolated and then submitted to electrophoretic separation. Various combinations of acrylamide and bisacrylamide were used and the one corresponding to the ratio 8 g / 230 mg was retained. A total casein deposit of 833 µg provided an adequate b-casein concentration (300 µg) for consistent animal immunization. Thirty Wistar rats were subjected to an immunization protocol for 35 days. The obtained antisera were used to optimize the Mancini technique and to assay b-casein in our samples at different storage times ranging from 3 h to 69 h/+4°C. A decrease in b-casein content from 0.85 mg ml-1 to 0.32 mg ml-1 was detected. These results demonstrate the vulnerability of b-casein at low temperatures and provide information on the origin of milk and its application for dairy or cheese production. In addition, our study confirms the usefulness of immunochemical techniques such as the Mancini test in the determination of β-casein.

Juvenile drug-related crime in Serbia: Current situation and tendencies
Authors: Lajić Oliver , Didanović Ana
Published: January 2023

The growing involvement of minors in drug-related crimes is a problem that our country has been struggling with in recent years. First, it is necessary to point out the increase in the number of drug-related crimes in which juveniles appear in the role of perpetrators, which is the main goal of this paper. The need to highlight the increase in the number of criminal charges and convictions of juveniles for this group of crimes stems from the fact that in other categories of crimes there is a decrease in the number of juvenile offenders, and at the same time, in the group of crimes involving drug abuse the number of juvenile offenders is growing. A worrying circumstance is that juveniles keep pace with adult perpetrators of drug crimes, as in both categories there is a noticeable trend of increasing the representation of this group of crimes. Data from judicial statistics, imprimis of the Republic Bureau of Statistics, provide insight into the new state of juvenile drug crime, while data from the Ministry of the Interior show more detail in the development of this delicate phenomenon. The criminal offense of unauthorized production and distribution of narcotics and the of criminal offense of unauthorized possession of narcotics are committed by a large number of juveniles, and over a period of ten years there has been a marked increase in the number of committed offenses. The age structure of juvenile perpetrators of drug crimes is such that the majority of perpetrators are older juveniles, that is persons aged 16 and 17. When it comes to gender structure, boys constitute the dominant category. The goal of this paper is to draw attention to the prevalence of this problem by presenting the current situation and trends of juvenile drug crime.

Objective. To determine whether the method of acquiring IT knowledge affects computer literacy and how the implementation of HIS affects work and quality control. Methods. The research was conducted as a cross-sectional study, in the population of nurses. The sample consisted of 116 respondents, who voluntarily agreed to participate in the research. Results. Respondents who have formal education in informatics showed a higher level of knowledge than respondents who do not. It was established that there is a statistically significant difference in computer literacy between respondents who acquired IT knowledge in different ways. Those who rated themselves better have higher scores on the knowledge test. The data indicate the existence of statistical significance of differences depending on the self-assessment of one's own computer skills. Almost half (46.7%) of respondents believe that the implementation of HIS made work easier, while 26% of them believe that it had no impact on work or made work more difficult. The largest percentage (59.9%) of respondents believed that the health information system facilitated quality control. Conclusion. The way of acquiring knowledge has the greatest influence on the computer literacy of nurses: nurses who had formal IT education showed a higher level of computer literacy. Nurses believe that thanks to the implementation of HIS, the quality control of the provided services has been significantly improved. The majority of health workers in the initial stages of introduction, application and development of the health information system had no formal education. Nevertheless, with the support of the institutions, they made a significant contribution to the implementation of HIS in the Republic of Serbia.

Published: January 2023

The issues of the paper are given a concise overview, of the current state of capabilities of "small states" for informational action. In the context of "small states" specific abilities necessary for informational action are described and the basic challenges of their development analyzed. Also, a brief critical review of the theoretical and doctrinal bases of the information activity of the institutions of the Republic of Serbia is given. The emphasis in the description of capabilities is on those that are carried out by informative and perceptive methods (propaganda, managing the perception of the opponent, disinformation, psychological operations, deception), about those that are carried out by informational and technical means (by attacking critical objects of the national infrastructure, cyber-attacks), precisely because of their dominant base on knowledge, good organization and the use of easily available resources and means, and not on technical-technological supremacy, large material-financial investments and expensive technology, unattainable for "small states".

The issue of the annual volume of afforestation directly affects changes in the degree of forest cover and represents one of the most topical and complex activities of the forestry profession. Therefore the main aim of this research was to determine the current trends in the scope of afforestation and make projections about future courses by monitoring multi-year trends. Norway spruce and Austrian pine are coniferous forest species most frequently used in afforestation in Serbia. Oaks are broadleaved species most frequently used in afforestation, although beech forests are the most common forests in Serbia. For that reason, we analysed the trends in the scope of afforestation with these tree species in the period from 2002 to 2021. All species, except for beech, recorded a negative trend in the scope of afforestation. The analysis of data related to the extent of afforestation, together with the data related to the level of subsidisation provided by the state for afforestation, gives an insight into the dynamics of afforestation, based on which recommendations and guidelines can be given for planning and carrying out work on further afforestation, the establishment of new forests, which would, in turn, increase the degree of forest cover.

Insurance, as a source of society's aspirations, represents the association of all those who are exposed to the same danger. The coronavirus pandemic has affected various aspects of life, including the insurance industry. Life insurance is one of the types of insurance where the obligations of insurance companies to policyholders have increased during the coronavirus pandemic. The paper analyzes the normative complex of the insurance premium with the specifics and characteristics of this topic. We consider it important to comprehensively explain the premium as an essential element of the life insurance contract. The analysis includes how the coronavirus pandemic is affecting life insurance premiums. This period of change could be a turning point and lead to transformational changes in the life insurance industry.

Insulation stresses of power equipment exposed to non-standard overvoltage waveforms
Authors: Jasika Ranko , Mrvić Jovan , Obradović Stefan
Published: January 2023

During its operation, electrical equipment is constantly exposed to overvoltages of various waveforms, such as lightning discharges, switching operations, faults, etc. Therefore, adequate selection of overvoltage protection and equipment insulation withstand voltages are key factors in increasing system reliability. In general, insulation coordination is carried out by analyzing the insulation behavior for standard impulse and switching overvoltage waveforms. However, overvoltages that occur in operating conditions can significantly deviate from the standard waveforms of insulation withstand voltages, in terms of the front time, the duration of the wave, the existence of highfrequency components as result of reflections in the facility and other factors. This paper presents possible methods of assessing the behavior of equipment insulation for real voltage waves to which the insulation is exposed during exploitation and which deviate from standard waveforms, by analysis in the frequency domain. As there are different components in the overvoltage signal at different frequencies, which a different energy, the main goal of this paper is to analyze the insulation characteristics of a specific transformer from the point of view of the energy spectral density of the voltage wave that occurs at its terminals when an atmospheric discharge occurs. The analysis is based on the determination of the safety margin on the entire frequency spectrum of the overvoltage wave, that is, on the calculation of the so-called FDSF (Frequency Domain Severity Factor). The calculation results show that although the overvoltage amplitude is lower than the withstand voltage of the transformer insulation with an appropriate safety margin (the condition of the classic approach to insulation coordination is satisfied), the spectrum analysis of the voltage wave in the frequency domain shows that the insulation may still be compromised.
The examination of the specific thermal resistivity and moisture of cable bed in laboratory conditions
Authors: Simić Ninoslav , Obradović Stefan
Published: January 2023

This paper at first hand briefly presents examples of the maximum permitted current changes for one cable depending on the specific thermal resistance soil value rz. It is emphasized that the permanently permissible current load of the cable should be calculated using a constant value rz in design - Then, for two cases from field, two samples were examined. The first sample is undisturbed soil from the cable route and the second sample is specially prepared cable bed. The corresponding rz values were obtained using the needle probe method in the laboratory. The difference is pointed out between the measured values of specific thermal resistivity and moisture of the samples. Some samples were being dried in thermal chambers and the others were being dried on ambient temperature. For drying in thermal chambers, based on experience for cross-linked polyethylene cables, the temperatures of 60°C to 90°C were selected for the first case while in the second case the temperature of 20°C over a long period of time was applied. The results obtained were analyzed and shown in appropriate tables and graphs. At the end of this paper the moisture of the soil was calculated for sampled cable bed that corresponds to the value of rz of 1(Km/W). The composition of the cable bed that allows the designed value of the rated power of the cable to be achieved is proposed.

Published: January 2023

The paper analyzes the levels of magnetic flux density in the apartment located above the 10/0.4 kV distribution transformer station. During the first magnetic field testing, it was concluded that in the case of the rated load of the transformers, increased values of magnetic flux density would occur in the apartment. The main sources of magnetic field in the apartment were the busbars and cable lines connecting the transformers and the 0.4 kV distribution cabinets. For that reason it is proposed to apply measures to reduce the levels of magnetic flux density, which are described in detail in the paper. After implementing the proposed measures, magnetic field testing in the apartment was repeated. The paper presents magnetic field testing results before and after the application of the measures and gives a conclusion regarding the effectiveness of the applied measures as well as regarding the compliance of the levels of magnetic flux density with the exposure limit prescribed by the current national regulations.

Therefore of great operational importance is to have information about this temperature estimated with the utmost accuracy. It can be measured directly using built-in temperature sensors or determined indirectly. With the increasing penetration of renewable energy sources into the high-voltage transmission system, the fundamental changes happen in the way conventional generating units work, including hydrogenerators. They are facing the new operating modes characterized by rapid load changes and an increased number of start-stop cycles. These modes of operation lead to additional thermal stress of the hydrogenerator parts, including the rotor. In order to be able to respond to new demands that they are faced with, it is necessary to estimate the actual thermal capacity of the rotor and its influence on the dynamic hydrogenerator PQ capability curve.

The algorithm of reactive power dispatching "per generator" realization is presented in the paper. Dispatching "per generator" and "per grid" are two modes of reactive power dispatching used by coordinated reactive power and voltage regulator (GRRS). Reactive power dispatching "per generator" ensures equal heating of the generators, while dispatching "per grid" ensures maximal reactive power reserve when generated reactive power either increases, or decreases. Reactive power dispatching "per generator" is more complex for realization because the dispatching criterion may have wider generator's reactive power operation area than the working capability curve. In these cases, the additional limiting of the generator reactive power is necessary, while other generators take over the remaining reactive power, still considering the reactive power dispatching criteria "per generator" and the limits of the remaining generators. Both reactive power dispatching modes are presented in two examples, while operating near and far from the limit area. Eventually, as the verification of the algorithm and its realization, the operating results of GRRS while dispatching "per generator" is active, are presented.
Some penal and criminological aspects of criminal offences against economic interests
Authors: Milić Ivan
Published: January 2023

Criminal offences against economic interests are prescribed in the separate chapter of the Criminal Code of the Republic of Serbia. It is about 29 incriminations. Except that these offences are prescribed in the Criminal Code, such incriminations are prescribed and by the other laws. Author of this paper refers to certain penal and criminological aspects of the mentioned offences. At the beginning of paper there is a word about punishable acts in the field of economic interests. A chapter of work is dedicated to data on the frequency of occurrence of such offences. Author emphasizes certain specifics in regard to the enforcement of criminal sanctions against persons convicted for offences against economic interests.
Labor protection of nannies

Published: January 2023

Nannies work is specific and highly sensitive, considering that it includes keeping and caring for children according to their age, taking care of physical and psychological health, safety, nutrition and hygiene, respecting their rights, personal integrity and dignity. The nannies job description includes taking care of children's daily rest, play, entertainment, school duties, free activities, and may also include taking children to and from school, on recreational and additional educational activities, with continuous monitoring and improvement of their physical, emotional, intellectual and social development. Education and upbringing of children is also an important segment of the nannies activity, as well as teaching life and social skills, according to the parents instructions. Bearing in mind the peculiarities and nature of the job of a nanny, there is a need to more precisely determine their labor protection in the law of the Republic of Serbia. By creating a more precise legislative framework for the performance of nannies, multiple benefits would be achieved: nannies would receive a higher degree of labor law protection, and parents and children would have greater security, because it would be possible for children to be cared for by professionally qualified persons in an adequately arranged space, in the prescribed manner under the continuous supervision and control of competent institutions over their work.
Legal protection and empowerment of vulnerable adults in Serbia

Having in mind demographic trends and especially growing number of the population in the old age, it is very important that family law deals with the needs of the vulnerable adults. In 2021 in Serbia the percentage of the population aged 65 and older is 21.3%. The number of users in Centres for social work that are deprived of 'transactional' ('contractual') capacity is growing (in 2017 13.075 persons are deprived of the 'transactional' ('contractual') capacity. Having in mind UN Convention on the Rights of Persons with Disabilities (Serbia has ratified the Convention in 2009) in this paper authors analyse legal changes in the procedural law which aim is protection and empowerment of vulnerable adults in Serbian law. One solution is limitation of the deprivation of 'transactional' ('contractual') capacity in a way that the decision is to be to reexamine in the period of maximum three years (Law on Non-Contentious Proceedings amendments 2014). Other solution is the obligation of the court to define legal operations which the person deprived of the capacity can undertake by himself/herself and especially if this person can exercise his/her elective right (Law on Non-Contentious Proceedings amendments 2022). The authors analyse proposed legal changes in the family law which aim is to empower vulnerable adults. The recent Draft Law on Amendments to Family Act empowers vulnerable adults in the several ways. It is proposed to abandon the existing institution of "deprivation of legal capacity" and to keep only the institution of the "limitation of legal capacity". It is proposed that court in the decision on limitation of 'transactional' ('contractual') capacity should determine the legal operations that a person partially deprived of capacity may not undertake independently. The Draft Law on Amendments to Family Act adds the legal acts to legal operations which the person deprived of capacity may undertake. This solution empowers vulnerable adults giving them wider circle of independent rights. It is proposed that the guardianship authority is obliged to protect the dignity and well-being of the ward; try to limit the rights of the ward as little as possible; encourage the ward's independent decision-making; provide him/her support in decision-making, as well as the participation in community life; take into account all the specifics of the ward's personality and accept his decisions, opinions, wishes, and attitudes, unless it is in conflict with the welfare of the ward. In addition, it is proposed to stipulate the guardian's obligation to make sure that the adult ward receives all the information on issues that concern him/her in a timely manner and to take into account in the utmost extent possible the ward's decisions, opinion, wishes and attitudes when performing the guardian's duties.
Examples of provincial governors' jurisdictions in ius quod ad res pertinet in Rome
Authors: Kulauzov Maša , Milutin Milan

Several topics are covered in the paper. Firstly, a list of sources of law which regulates the issue of the jurisdictions of provincial governors is given form the broader ones to the narrower ones. Jurisdiction of a provincial governor used to come into being in the moment of his entrance to the province. In case he leaves it, his jurisdictions would stop and he would become a private individual. The substitution of the personal jurisdiction of provincial governors, which was significantly shaken by the constitution of Caracalla in 212, with the territorial one, appears to be obvious at the end of the Dominate. The governor used to have civil and military jurisdictions. The former included judicial and administrative powers. Judicial jurisdictions were comprised of those in criminal and those in civil matter. Out of scope of the civil matter, only the examples of the jurisdictions of provincial governors in the matter of property law have been covered in this paper, which, according to the tripartition of Gaius, amounts to ius quod ad res pertinet. Provincial governors were authorised to adjudicate on almost all disputes arising from the everyday life during the formation, protection and termination of rights, not only those related to possessio, dominium, and iura in re aliena, but also those in the matter of obligationes and inheritance.
