Examining the effectiveness of the existing safety and crime prevention mechanism in Mopani district municipality, South Africa
Authors: Madima Khethiwe
Published: January 2024

Crime prevention has been recognised as one of the key national priorities in South Africa since the establishment of the National Crime Prevention Strategy (NCPS) in 1996. It is viewed to be the responsibility and duty of the South African Police Service (SAPS); however, with a range of crimes, caused by different factors, it is impossible to rely exclusively on the police to prevent crime. Thus, various stakeholders, such as businesses, communities, Non-Government Organisations, civil society, law enforcement and Municipalities, need to take a stand in maintaining peace and ensuring safety for law-abiding citizens within their municipal boundaries. This article examines the effectiveness of the existing mechanisms in ensuring safety in Mopani District Municipality (MDM). The Constitution mandates municipalities to take a lead in crime prevention to increasing people's feelings of safety and building safer communities. Using a qualitative research approach, a purposive sampling was used to select four municipal officials. The face-to-face interviews were conducted in Letaba local municipality, Greater Tzaneen local municipality, Ba-Phalaborwa local municipality and Maruleng local municipality. Data was analysed through thematic analysis. The results revealed that most local municipalities are involved in crime prevention through the establishment of the Community Safety Forums (CSF) who participate in tourism safety, school safety, road, social crime prevention and health safety. The findings revealed lack of resources, funding (Budget), political instability, lack of knowledge, training and experience as some of the major challenges hindering the effectiveness of local government involvement in crime prevention. The study recommends the establishment of a safety section in a municipality, professionalization of the crime prevention space, exploring other avenue for funding and municipal accountability to address safety issues
Ensuring the safety of citizens by rescuers/police officers in case of a chemical attack (accident at a chemical enterprise) in the conditions of marital law
Authors: Vaida Taras
Published: January 2024

The work deals with the urgent problem of ensuring the safety of life of the population in the conditions of martial law, introduced in Ukraine – providing premedical assistance to victims of a chemical attack (as a result of the action of dangerous factors of a man-made accident at a specialized chemical enterprise).

The potential possibilities of means of defeating the units of the chemical forces of the aggressor state are analyzed, the cases of the use of chemical weapons by the occupiers in relation to both the units of the Armed Forces of Ukraine and the civilian population during the war in Ukraine, as well as the real situations of destroyed chemical plants in many regions of the country, are described and summarized.

On the basis of the analysis of operational publications in the Internet and scientific works of a great number of scientists, the general algorithm of rescue actions during the evacuation of victims of a chemical attack/accident (workers/residents) was considered, modern approaches in the order of providing premedical aid both at chemical enterprises and at home conditions when people are injured by the most common chemical substances were clarified, recommendations concerning compliance by police officers with established rules of conduct at the scene of the incident are offered.

The main signs that characterize the beginning of a chemical attack in the conditions of martial law and allow the population to identify it quickly are given: 1) chemical alarm signals; 2) features of air raids or enemy artillery fire; 3) simultaneous mass death of small animals, birds and insects.

The peculiarities of the effect on the human body of such substances as chlorine, ammonia, hydrogen chloride (hydrochloric acid), nitrogen (nitrogen N), nitric acid, oxide (dioxin) of nitrogen, for each of which characteristic symptoms of damage for the victim are determined, the procedure for providing premedical aid to victims in case of damage by them, as well as under the influence of chemical weapons (sarin, phosgene) has been specified.

Based on the analysis of special literature and the results of the conducted research, a generalization was made regarding the importance of training the population in effective (and therefore safe) actions in the event of a chemical attack by the military units of the aggressor state (a man-made accident at chemical enterprises), the need to observe the established rules of conduct and safety measures in the case of a missile/artillery attack by the occupiers, regardless of the region or territory of fighting actions in Ukraine
On the issue of codification of urban planning legislation
Authors: Kvasnitska Olga
Published: January 2024

The subject matter of the article is conditioned by the discourse on the necessity to codify the urban planning legislation, approve the Ukrainian Urban Planning Code, and align its provisions with the norms of related branches of the legislation.

The purpose of the study is to specify the subject matter of the Urban Development Code's regulation and the sectoral affiliation of urban development relations, to define the structure of the codified act, and to change the requirements of the Commercial Code of Ukraine.

The research methods are based on the concepts and theories that describe the current state of the problem of the current urban planning and economic legislation in Ukraine and summarize the content of scientific works to conduct a broad analysis of the codification of the urban planning legislation while taking into account the existing legal system in Ukraine.

Results. The codification of the urban planning legislation, it is argued, provides for: increased transparency and ease of use of the norm; equivalent integrated nature of spatial planning; achievement of consistency of spatial planning and development in decision-making and regulation; decentralization and limitation of discretionary powers; and optimization of governing bodies in the urban planning sphere. The structured act of the Code will solve the problems of inconsistency and uncertainty of the conceptual apparatus in the field of urban planning, inconsistency with the land, environmental, and monument protection legislation, problems of technological support of urban planning activities, procedures for spatial planning, and public control over the development and adoption of urban planning documentation, with the maximum reduction in the number of acts of the current legislation.

Conclusions. It is proposed that the subject matter of regulation of the Urban Development Code of Ukraine should include social relations arising, changing, and terminating in connection with urban development activities based on the principles of a comfortable living environment and life cycle management of construction objects

The paper describes the design and software features of an intelligent sensor mounted on the oar shaft to register dynamic parameters characterizing the athlete’s interaction with the oar and the surface of the water in the supporting (water) part of the stroke. As a result of the study, experimental data were obtained, an algorithm was developed to analyze the strain-load curve and calculate the components of the resulting force applied to the oar during rowing. Based on a review of the literature corresponding to the research problem, as well as the data obtained during the pilot experiment, the prospects of using intelligent sensor systems as a means of quantitative description of the performance of sports movements in natural conditions are proved. The presented mathematical algorithm for calculating the values of the individual components of the resulting effort allows us to evaluate the ratio of the efforts made by the athlete and the resulting load on the paddle blades. The results allow us to conclude that the use of the method of mobile wireless tensometry for assessing the biomechanical parameters of sports movements is promising. Ways of further improvement of the developed methodology are determined.
The problem of mutual orientation determination of the accelerometer unit relative to body of the motion capture system
Authors:   Lomonosov Moscow State University, Kruchinin Pavel , Latonov Vasily , Matveev Denis
Published: January 2024

Two algorithms for determination of the rotation matrix of the inertial unit relative to the motion capture 6DOF target are discussed. Solution of this problem is necessary for further co-operative data processing of these sensors in biomechanical researches. In particular, it is required to estimate the acceleration of a moving object in the field of gravity from the data of a 3D accelerometer and a motion capture system. In this case, the local vertical of the well calibrated motion capture system can be used to separate the gravity induced components from the accelerometer data. Both algorithms use measurements obtained for static positions, which differ in orientation of instrumental axes relative to gravitational vertical and at the same time allow us to estimate systematic errors of accelerometers. The first algorithm assumes orthogonality of instrumental axes of inertial unit and does not take into account errors in information on scale coefficients of accelerometers. The algorithm uses equations wich are linearized in the neighborhood of a priori estimates of the unknown values. The second algorithm does not use a priori information about axes of instrumental frame. In this case, the accelerometer unit is recalibrated, and in addition to the zeros and scale factors, the non-orthogonal angles of the instrumental axes of the unit are determined. The immediate result of its work is a matrix, which allows us to determine projections of apparent acceleration on body axes of the motion capture system. Algorithms are tested on experimental data. The comparison criteria is the repeatability of estimated results obtained from different measurement samples. Processing the results of the trial experiment showed that for inaccurate microelectromechanical systems, the second algorithm produced more stable results.

Objective: to study the effect of a conditioned medium of mesenchymal stromal cells (MSCs) from different sources on human chondrocyte proliferation.

Materials and methods. To confirm functional activity, chondrocytes were cultured in a cartilage cell-engineered construct (CEC), including 5 × 105 cells and 5 mg of tissue-specific matrix from decellularized cartilage. The conditioned medium was obtained after culturing MSCs derived from human adipose tissue (AT), MSCs derived from the pulp of primary teeth and MSCs isolated from umbilical cord-derived Wharton’s jelly in a complete cell growth medium (CCGM). To evaluate the effect of MSC-derived secretome on chondrocyte proliferation, the conditioned medium, diluted 1 : 1 with CCGM, was added to wells containing chondrocytes. The effect of MSCs on human chondrocyte proliferation was studied by indirectly coculturing cells in CCGM using Transwell inserts. 5 × 104 MSCs were applied to the bottom of the lower chamber, and 5 × 104 human chondrocytes and 5 mg of matrix were placed in the upper chamber. Chondrocyte proliferation was assessed at days 7 and 14 by DNA quantification. Interleukin-6 content was determined as a marker of secretory activity of MSCs in the conditioned medium. The morphology of the samples was studied using histological staining methods.

Results. The ability of chondrocytes to produce cartilage-specific extracellular matrix was confirmed when forming cartilage CEC with tissue-specific matrix in a chondrogenic differentiation medium. When comparing the effect of the conditioned medium of MSCs obtained from different sources on the growth of human chondrocytes in vitro, increased proliferation was observed in all samples compared to controls. Indirect co-culture of MSCs with chondrocytes as part of CEC showed increased DNA amount in all samples at day 14, with the amount of DNA in the sample with MSC conditioned medium significantly higher than the control.

Conclusion. Studies on the effect of MSC conditioned medium on chondrocyte proliferation in 2D culture indicate a possible regenerative potential of MSCs for cartilage tissue repair. Within the scope of this work, we did not identify significant differences in the effect of secretome derived from MSCs that were obtained from different sources on chondrocyte proliferation. However, additional in vivo studies are warranted in the future.

Development of minimally invasive diagnosis techniques for complications in recipients, based on analysis of the levels of molecular and genetic biomarkers, is an urgent task facing modern transplantology. Transforming growth factor beta 1 (TGF-β1), which has multiple effects in the body, among the potential indicators of complications.

Objective: to assess the diagnostic significance of serum TGF-β1 in kidney recipients with graft dysfunction.

Materials and methods. The study included 129 kidney recipients aged 17 to 68 years and 35 healthy subjects. Serum TGF-β1 levels in the recipients were determined by immunoenzyme technique.

Results. Kidney recipients included 95 patients with laboratory and clinical signs of graft dysfunction, who underwent biopsy of the transplanted kidney, followed by morphological examination, and 34 recipients with normal graft function. Serum TGF-β1 levels in the kidney recipients were significantly higher than in their healthy counterparts (p = 0.00001); it did not correlate with most blood test parameters; with the glomerular filtration rate (GFR). Kidney recipients with graft dysfunction had significantly higher TGF-β1 levels than other recipients (p = 0.018). In recipients with graft dysfunction, morphological study revealed the following: acute tubular necrosis (ATN, n = 11), acute T-cell mediated rejection (ACR, n = 26), acute antibody-mediated rejection (AMR, n = 35), non-immune-mediated nephrosclerosis with signs of calcineurin inhibitor nephrotoxicity (CNI nephrotoxicity, n = 13), and recurrent glomerulonephritis (chronic graft rejection, n = 10). Recipients with immune-mediated graft injury (ACR, AMR and chronic rejection) had higher serum TGF-β1 levels than recipients with graft dysfunction resulting from other causes, p < 0.0001. Kidney recipients with serum TGF-β1 levels above the threshold value of 94.3 ng/mL had a higher risk of immune-mediated graft dysfunction than other kidney recipients (RR = 2.2 ± 0.22 [95% CI 1.46–3.46]) with 77.5% test sensitivity and 60.3% specificity.

Conclusion. The calculated threshold serum TGF-β1 level in kidney recipients can be considered as an auxiliary indicator of graft dysfunction resulting from acute or chronic rejection.

Authors: Stepanov V. A. , Vetchinnikova O. N.
Published: January 2024

Patients with chronic kidney disease are susceptible to developing acute pancreatitis. We present a rare clinical case of acute pancreatitis with the formation of pancreatic necrosis in a patient on peritoneal dialysis (PD), debuted with PD–associated peritonitis. On hospitalization, there were no diagnostic criteria for acute pancreatitis; treatment for dialysis peritonitis was ineffective. Repeated ultrasound examination revealed signs of diffuse changes in the pancreas and multi-chamber formation of the small pelvis. Refractory peritonitis, inadequate ultrafiltration, and unclear nature of formation in the pelvic were the grounds for diagnostic laparoscopy and removal of the peritoneal catheter. Abdominal inspection revealed spots of stearin necrosis over the entire surface of the peritoneum and the greater omentum; in the pelvis there were adhesions between the uterus and the rectum. Development of pancreonecrosis was confirmed by abdominal CT scan. Treatment of acute pancreatitis was without effect, type 2 myocardial infarction developed, and with increasing symptoms of multiple organ failure, death occurred.
Entre inconformismo e reformismo
Authors: FURTADO CELSO
Published: January 2024

RESUMO Trata-se de um artigo-síntese, onde o autor resume sua teoria do desenvolvimento e do subdesenvolvimento. Algumas ideias básicas são aqui apresentadas: a teoria econômica do desenvolvimento deve começar com o estudo da história; o subdesenvolvimento é um fenômeno histórico e econômico específico, que não pode ser pensado em termos de etapas lineares da história; esse fenômeno histórico deve ser estudado em termos estruturais, relacionando a história e os aspectos econômicos; a característica básica do subdesenvolvimento é a relação de dependência, expressa no sistema centro-periferia; no estudo do desenvolvimento o conceito básico para começar é o conceito de excedente social, suas formas de apropriação e utilização. O artigo termina com uma análise das frustrações de um reformista. O protecionismo, que era justificável numa primeira fase da industrialização, foi mantido por muito tempo na América Latina; numa segunda fase, era necessária uma política econômica ativa para as exportações. Por outro lado, o risco populista sempre esteve presente, enquanto os reais problemas sociais relacionados ao alto nível de concentração de renda não foram resolvidos.
O Acordo de Bretton Woods e a evidência histórica. O sistema financeiro internacional no pós-guerra
Authors: KILSZTAJN SAMUEL
Published: January 2024

RESUMO O Acordo de Bretton Woods refletiu a hegemonia dos Estados Unidos no pós-guerra e o dólar estava vinculado à commodity que historicamente representou o dinheiro internacional - o ouro. No entanto, os demais países desenvolvidos não puderam permitir a conversibilidade da moeda até 1958 e em 1960 a crise do dólar já era evidente. Da “escassez do dólar” à crise do dólar, Bretton Woods foi, na verdade, apenas uma miragem. O aspecto mais significativo da crise do dólar foi certamente o desenvolvimento do mercado Euromoney. Na atualidade, com o “padrão ouro”, por um lado, e projetos de moeda artificial, por outro, o sistema monetário internacional está evoluindo para um sistema oligopolar.
Keynesian theories of investment: neo-, post-, and new
Authors: FAZZARI STEVEN
Published: January 2024

ABSTRACT The general objective of this piece is to analyze the formulations developed by three interpretative strands of Keynes’ investment theory, specifically with regard to the interrelationships between real and monetary-financial variables. After highlighting the innovative character of Keynes’ formulation on the issue, the author goes through the approaches of neo-Keynesians (neoclassical synthesis), post-Keynesians, and New Keynesians, in an attempt to focus on the central question of the article, that is, to assess the existence or not of possible relationships between the new Keynesians and the two other approaches with regard to the links between finance and investment. In particular, the author aims to assess whether or not the formulations of the new Keynesians represent a convergence between neo and post visions.

Abstract An insect gall inventory was carried out in two reserves of the Peruvian Amazon, Allpahuayo-Mishana National Reserve and Quistococha Regional Reserve, both situated in Iquitos, northeastern Peru. Four vegetation types were surveyed between December, 2021 and December, 2022: terra firme forest, white-sand wet forest, and white-sand dry forest in Allpahuayo-Mishana National Reserve, and palm swamp forest in Quistococha Regional Reserve. Overall, we found 262 gall morphotypes, distributed across 75 host species representing 66 plant genera and 30 families. Fabaceae was the plant family with the greatest number of gall morphotypes (n = 48), followed by Calophyllaceae (n = 21) and Euphorbiaceae (n = 20). The plant genera that supported the highest diversity of galls were Caraipa (n = 17), Eschweilera (n = 16), Tapirira (n = 16), Micrandra (n = 14), and Iryanthera (n = 10). The plant species Tapirira guianensis (n = 16), Caraipa utilis (n = 14), Micrandra elata (n = 14), Eschweilera coriacea (n = 11), and Sloanea parvifructa (n = 10) exhibited the highest richness of galls. Among the host plants, C. utilis stands alone as the only species noted as both endemic to the Amazonian region and bearing a Vulnerable (VU) conservation status. The leaves were the most attacked organs (90% of all galls). Most morphotypes are glabrous (89%), green (67%), globoid (53%), and one-chambered (91%). We found galling insects belonging to the orders Diptera, Thysanoptera, Lepidoptera, and Hemiptera. The galling insects of Cecidomyiidae (Diptera) were the most common, inducing 22% of the gall morphotypes. In addition to the gallers, we also observed the presence of successors, cecidophages, and parasitoids. Among the sampled vegetation types, the terra firme forest presented the highest richness of gall morphotypes and host plant species. This is the first systematic inventory of insect galls in this part of the Peruvian Amazon.

Published: January 2024

Bu makalede, Türkiye ekonomisine özgü bazı makro finansal istikrarsızlık değişkenlerinin kamu sermayeli bankaların finansal istikrar performansı üzerindeki etkisinin incelenmesi amaçlanmıştır. Çalışmada, 2017-2022 dönemi boyunca çeyreklik veriler kullanılmıştır. Çalışmanın eşbütünleşme, uzun ve kısa dönem ampirik amaçlarına ulaşmak için ekonometrik model olarak panel PMG/ARDL tekniği kullanılmıştır. Gelişmekte olan bir ekonomide yapılan bu çalışmanın bulgularında, modelde yer alan finansal istikrarsızlık göstergeleri ile bankaların finansal istikrarları arasında önemli düzeyde bir eşbütünleşmenin varlığına rastlanılmıştır. PMG etki analizlerinde ise, yurtiçi toplam kredi hacmi, kredi risk primi ile takipteki kredilerin oranı göstergelerinin uzun dönemde bankaların istikrarını azalttığı, kısa dönemde ise bankaların bu durumu pozitife dönüştürerek başarılı bir şekilde yönetebildikleri görülmüştür. Son olarak, istikrarsızlığa neden olan göstergelerin hem reel sektör hem de finansal hizmetler sektörü için ekonomik sistemde önemli bir işlev gören bankaların finansal istikrarı üzerinde uzun dönemde negatif bir etkiye ve eşbütünleşik bir ilişki içinde olduğuna dair kanıtlar istatistiksel olarak anlamlı bulunmuştur. Bu bağlamda, bankacılık sektörünün istikrarına yönelik elde edilen kanıtlar, bankacılık sektörüne yönelik politika yapıcılar, akademik çevre, düzenleyiciler ve yatırımcılar içinde çeşitli çıkarımlar sunmaktadır.
The construction history of the Ledenice castle: application of the archaeology of standing structures
Authors: Janeš Andrej , Karković Takalić Palma , Gligora Valerija
Published: January 2024

The remains of the Ledenice castle are situated on the top and the south slope of a hill named Gradina, in the hinter-land of Novi Vinodolski, on the southeast rim of the Vinodol valley. The castle is known from written sources at least from the mid-13th century. The castle and the settlement continued to flourish from the 13th till the 16th century, stag-nating during the 17th century, to be abandoned through the 18th and 19th centuries. Since 2019, the Department of Art History of the Faculty of Arts in Rijeka, in collaboration with the Croatian Conservation Institute, has been documenting the standing structures. The aim of the project is to document the remaining structures, analyze them, and establish the construction history of this site.During the 2021 campaign, the remains of the central castle have been surveyed and documented. Using the archeo-logical methodology of the stratigraphy of standing structures, the remains of the castle have been analyzed. Six dis-tinct construction phases have been identified among the standing structures. The earliest one is represented by the remains of a possible church dated to the 12th/13th centuries. That structure was supplemented by the construction of the castle that was enlarged during the next three construction phases, dated from the 13th to the end of the 15thcentury. The change of the owner, from the noble Frankopan family to the Habsburg Military Frontier, caused new construction changes during the 16th century. The last phase is represented by the physical remains of trenches and pill boxes of the Italian army during World War II. The aim of this paper is to present the results of the structural and field survey of the Ledenice castle and to show the possibilities of the analysis of standing structures in archaeology as one of the noninvasive field methods.

Published: January 2024

According to the Department of Health, diabetes is among the main causes of death among Filipinos. As a result, medical administrations must provide high-quality services. Patients, treatments, and particularly rural medical centers should all receive adequate screenings from the government. The goal of this study is to find out how satisfied diabetic patients are with the medical care they receive. Twenty-two (22) people with diabetes were included in the study. A survey will be utilized to gather information and data from a group of diabetic patients. The results show that: (1) there is no substantial difference in diabetic patients' satisfaction based on sex demographics; (2) there is no substantial difference in diabetic patients' satisfaction based on age demographics; (3) there is also no substantial difference in diabetic patients' satisfaction based on the establishment; and (4) there is a substantial difference between the patient's satisfaction and the medical services offered. When it comes to the score mean, diabetic patients' satisfactions are inside the extremely satisfied verbal description. The majority of the respondents were between the ages of 47 and 54. 12 females, 10 males, and 15 of them were in one medical establishment and the others were in the second. Despite their demographic differences, their satisfaction levels were quite close. Since there is a significant difference between the medical services dimension and the mean score of the overall medical structure and process is lower, there is a slight improvement for the medical establishments to focus on the medical structure and process, specifically the facilities, transportation convenience, and the length of waiting which the patients scored lower than the other parameters.

This study aims to educate Titi Laras Damina's learning in Kartika Senior High School students. The research was conducted on representatives of 10 grade-11 social studies students through 3 stages, namely (i) pre-test; (ii) theoretical and practical education using the Direct Instruction method; and (iii) post-test. The results showed that the average pretest theoretical value was 71 and the posttest average was 96.5. The results of the comparison of the pretest and posttest did not significantly increase after the learning was carried out. The results of the N-Gain calculation show that the average N-Gain value is 34% (N-Gain 40%) indicating that Titi Laras Damina's learning is theoretically ineffective for Senior High School students in grade 11 social studies. This is due to the comparison of pre-test scores. and the post-test was not so high and the students' knowledge was sufficient of Titi Laras theory. Practically there is a significant improvement because before learning students have not been able to mention the notes in each barrel. However, after learning using the direct instruction method there is an increase in musicality in students. Students can now say the notes in each barrel after it has been held. From this research, it is hoped that students can master the knowledge of Titi Laras Damina in theory and practice.

Published: January 2024

Information and communication technology (ICT) plays a critical role in improving educational quality. Because of its strengths in facilitating administration operations such as data storage, knowledge management, and decision-making, ICT solutions for administration and management are currently popular in universities. Here, to support teaching and learning processes as well as to achieve the veritable tools for administrators in private universities, the purpose of this study was to gain a better understanding of how ICT applications are used, the tools used by the school administrator, and the efficacy of ICT applications for administrative and managerial tasks at universities. It is obvious that lack of commitment by Administrators; lack of ICT strategy; lack of competent staff to manage the ICTs and low skill level of the administrators led to the reasons for poor use of the ICTs in Universities. Other reasons that added to the underuse of the ICTs are insufficient budget and irregular power supply. This paper presents a survey of the literature on ICT applications and their efficacy in university administration functions. The findings provided insight into how administrators might improve and expand their use of ICT in daily administrative duties to make their work more efficient and effective. Finally, recommendations for university administrations to improve their ICT understanding and practice will be explored.
