A method for quantitatively investigating the relationship between local structural properties (local basis weight, local thickness, local density and local load carrying factor (local fiber orientation)) and local tensile deformation (local strain and local temperature increase (thermal energy dissipation)) was introduced. It was found by utilizing the method for 70 g/m2 sack paper strips that relative basis weight, relative thickness, relative density and relative load carrying factor combined explain 31% and 26% of total variation in relative strain and relative temperature increase, respectively. Best single predictors for relative strain were relative basis weight (R2=0.14) and relative load carrying factor (R2=0.11). On the other hand, relative basis weight alone was the best predictor for relative temperature increase deformation distribution parameters from the perspective that high relative temperature increase is preceded by the high relative strain, it could be said that the relative strain explains 45% of the total variation in the relative temperature increase (R2=0.45). Thus, these two parameters describe the deformation in partially different ways. Based on this study, it can be concluded that the introduced method offers a promising tool to quantitatively investigate the separate/combined influence of local structure properties on the local deformation accumulation initializing the failure of paper.

Published: February 2024

¿Logra la educación superior de alta calidad nivelar las desigualdades de base que existen entre estudiantes de distintos orígenes socioeconómicos? En este artículo comparamos la inserción al mercado laboral de los beneficiarios del programa Ser Pilo Paga y sus compañeros de clase alta que se graduaron en Derecho e Ingeniería de Sistemas de una universidad de élite. Los resultados muestran que los ‘pilos’ han experimentado un grado importante de movilidad social y están teniendo un impacto positivo en sus comunidades, pero reciben salarios más bajos que sus pares y experimentan emociones difíciles al enfrentarse al mercado laboral. Así mismo, revelan que las experiencias de los ‘pilos’ varían considerablemente de una carrera a otra, lo cual parece explicarse por la calidad del mercado laboral y la importancia que tienen el capital social y cultural en las profesiones escogidas.
Reflexiones sobre equidad en la educación colombiana: una aproximación a las pruebas saber 11 del 2022 desde la perspectiva conceptual de Pierre Bourdieu
Authors: Pardo Mercado Jesús David , Orjuela Albarracín Darling Jeaneth
Published: February 2024

Este estudio analiza la relación entre los resultados de las pruebas Saber 11 y algunas variables sociodemográficas a la luz de diversos elementos conceptuales de Pierre Bourdieu. Para ello, explora la forma en la que nociones como capital cultural, habitus, capital económico o campo permiten comprender los resultados de este tipo de pruebas estandarizadas. La investigación busca esclarecer la manera en la que ciertos factores ajenos a lo estrictamente escolar podrían estar asociados al rendimiento en tales pruebas y a la forma como estas podrían contribuir en la reproducción y perpetuación de las desigualdades sociales.
Alain Touraine o la sociología del actor social. in memoriam
Authors: Valencia Gutiérrez Alberto
Published: February 2024

El 9 de junio de 2023 murió en París a la edad de 97 años el conocido sociólogo Alain Touraine, autor de un vasto conjunto de investigaciones y de libros que gira alrededor de dos problemas fundamentales: una nueva sociología del actor social y una indagación por las características de las sociedades contemporáneas. Su proyecto intelectual se podría resumir en la siguiente frase: refundar la sociología a partir del reconocimiento de la primacía de la acción social. Y todo ello en el marco inicial del debate con el modelo estructuralista de los años sesenta en Francia, pero igualmente con el funcionalismo parsoniano, predominante en la sociología norteamericana de la misma época. La sociología de los movimientos sociales, por la que es más conocido, es un corolario de su preocupación fundamental por el carácter creativo de la acción social. A estas dos orientaciones de su trabajo sociológico habría que agregar el interés por el estudio de América Latina, desde el Río Grande hasta la Patagonia. Este artículo pretende construir una presentación sintética de los aspectos centrales de su obra siguiendo sus propios criterios: “más que distinguir cronológicamente las fases de mi producción, lo que procuro es comprender su unidad, pues hoy tengo la convicción de que siempre me he planteado las mismas cuestiones, aunque no del mismo modo y probablemente con un grado de conciencia insuficiente” (2000, p. 114).
La vieja guerra de los jóvenes. ¿es el bono demográfico una causa del conflicto en Colombia?
Authors: Uprimny Añez Simón
Published: February 2024

En la teoría demográfica del conflicto, la composición de una población puede ser causa de violencia. En Colombia, este enfoque ha sido poco abordado, a pesar de que el conflicto se intensificó en los años noventa y, paralelamente, el país entró en un período de bono demográfico (poblaciones jóvenes y en edad de trabajar muy numerosas). Para determinar si esa particular estructura poblacional influyó en la evolución del conflicto, se escogieron municipios de cuatro regiones diferentes y se analizaron algunas variables de población, conflicto y condiciones socioeconómicas entre 1973 y 2005. No se encontró una relación automática población joven numerosa = conflicto, pero todos los municipios más violentos tenían poblaciones jóvenes y en edad de trabajar importantes y condiciones de vida deficientes, lo que invita a continuar investigando la relación entre bono demográfico y conflicto.
Cyclic liquefaction in transitional and non-transitional tailings
Authors: Cartwright Abigail , Coop Matthew , Wei Li , Fourie Andy
Published: February 2024

Tailings have previously been identified as having the types of mixed mineralogies and gradings that can make them susceptible to having non-unique critical states and normally compressed states in laboratory element tests. This paper addresses how this mode of behaviour would affect their resistance to undrained cyclic loading, contrasting two triaxial studies, one on a tailings that has a conventional behaviour and one transitional. To demonstrate the influence of transitional behaviour it was necessary to create samples with as wide a range of initial specific volumes as possible, while trying keep the sample preparation methods the same for loose and dense samples. It was also necessary to examine the cyclic data in non-conventional ways, notably in the volumetric plane to highlight better the effects of initial sample specific volume. It is shown that, as previously determined for monotonic loading, the initial density has much less influence on the cyclic behaviour of a soil with transitional behaviour than it would for a conventional soil, and it is instead the stress history that is very much more important. Samples following their respective normal compression lines exhibit similar behaviour, but overconsolidation significantly enhances resistance and a sample that arrives at a given state by the undrained reduction of p′ due to cycling also has a much higher resistance.

Authors: Angdiarto Stella Patricia , Chen Chun-Tao , Chang Ta-Peng , Shih Jeng-Ywan
Published: February 2024

To reduce environmental pollution and conserve natural resources, calcined oyster shell ash (COSA), class F fly ash (FFA) and flue gas desulfurisation gypsum (FGDG) were used in an attempt to improve the engineering properties of alkali-activated ternary cementitious paste. The COSA – obtained by calcining crushed oyster shells at 800°C for 3 h and then grinding to pass through a no. 100 sieve – was used to substitute FFA at rates of 2.5, 5.0 and 7.5 mass%. The alkali solution used was 10M sodium hydroxide and sodium silicate with a modulus of 2.5. The hardened paste with 7.5% COSA, 1% FGDG and ratio of weight of added water to dry binder of 0.09 at 56 days had the highest compressive strength of 62 MPa. Microstructural analyses (scanning electron microscopy and energy-dispersive X-ray spectroscopy) showed that the resulting calcium aluminosilicate hydrate gel was found to have a compact microstructure, which improved the compressive strength of specimens. In summary, COSA successfully replaced natural limestone as a calcium oxide activator to manufacture an alkali-activated ternary cementitious paste containing FFA and FGDG.

Published: February 2024

An investigation into the effects of external sulfate attack (ESA) on the mechanical and microstructural properties of steel fibre-reinforced sprayed concrete (SFRSC) was conducted. Crimped carbon steel fibres, 40 mm long, were used as reinforcement in three different mixtures with specified fibre contents of 30, 60 and 90 kg/m3. Cylindrical specimens, drilled from SFRSC panels, were subjected to sulfate attack for up to 270 days. Double-punch tests were used to determine the matrix crack strength and the post-crack tensile strength of the SFRSC. The effective fibre content of each specimen was determined by inductive tests and subsequently correlated with the mechanical results. Scanning electron microscopy was used to evaluate the phases formed in the concrete pores during the ESA. The results showed that fibre reinforcement may reduce cracking due to ESA.

Published: February 2024

An academic–industry team present the results of research conducted into the current benefits being derived from the use of digital twins across the entire life cycle of an asset. The team reviewed the benefits being derived by the asset-management community, as it is through this that through life productivity and effectiveness benefits will be realised. The team conducted a review of relevant literature, surveyed 122 practitioners and worked with their industry partner and a UK professional body to validate their conclusions. Specifically, (a) the authors examined the current application of digital twins in three industry sectors: process industries, infrastructure (civil engineering) and manufacturing. (b) The authors grouped the data according to role types – namely, professionals working predominantly in design and build and professionals in the operation and maintenance part of the life cycle. As regards the sector results, the responses were found to be contradictory. When controlling by role type, the results are more cohesive. Individuals involved in the operation and maintenance stages consistently indicated that digital twins are not delivering on their promise. The authors present a series of problem statements to define the current state, together with some managerial recommendations, and the authors propose further work to establish detailed guidance for infrastructure sector projects.
A phenomenological inquiry of Building Information Modelling macro-adoption in Uruguay

Published: February 2024

Building information modelling (BIM) application in the architecture, engineering and construction (AEC) sectors has received attention, particularly in most Global North countries. However, there is a dearth of literature on its application in the Global South context. This research explores insights into the uptake and use of BIM in the Uruguayan AEC sector and proposes recommendations for accelerating its adoption. This study adopted the phenomenological research design. Through interviews with experts, this study relies on phenomenological analysis of a purposely sampled group of (n = 7) experts in BIM in the Uruguayan AEC industry. The discoveries and findings confirm that BIM is still at an early stage of maturity, and many practitioners still need to be convinced of its benefits. Therefore, pilot projects and the development of BIM guidelines are essential to align industry procedures and demonstrate the benefits of implementing BIM to convince hesitant professionals and increase levels of adoption. Furthermore, organisations’ main implementation drivers are external forces such as client requirements or the need to acquire a competitive advantage. This study’s findings imply that BIM diffusion dynamics in Uruguay are more aligned with a top-down approach, thus highlighting a design for ‘push’ by authorities such as the government. Overall, this study fills a research gap in the Uruguayan AEC industry and provides an academic reference background for policymakers for future actions. The paper is of value, as it contributes to the current state-of-the-art BIM research by drawing insights from the AEC industry in a typical developing country context.

This paper presents the design of a drive system for a low-power fan. This system consists of a brushless DC motor (BLDC) and a low-voltage inverter. The rotor of the motor is built of four offset layers, inside which permanent magnets are placed. This design minimizes the cogging torque of the machine and guarantees trouble-free operation (no possibility of magnets breaking off). A lowvoltage inverter provides motor speed control over a wide range and limits the motor's starting current. The paper explains the algorithm of sensorless control reducing the price of the drive (no position sensors and their wiring), compares the legacy motor with the new motor and shows a significant reduction in power consumption of the new drive.

Ministry of Defence expenditures impact on economic growth of Ukraine
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, KOVAL Oles
Published: February 2024

B a c k g r o u n d . With the start of the second stage of the Russian-Ukrainian war, the Government of Ukraine and its military command faced an objective examination of the results of years of efforts to develop Ukraine's national security and defence sector. At the same time as defence capability was being enhanced, economic performance was on the rise. This led us to test the hypothesis of whether the increased defence capability caused this growth. This study aims to clarify the relationship between military expenditures and economic growth in Ukraine. The object of the study is a consistent and long-term process of economic growth of the state along with an increase in the level of defence capability as a result of military expenditures in the context of financial support from the Ministry of Defence of Ukraine. Methods. Theoretical methods: analysis, synthesis, abstraction, generalisation, induction, deduction, explanation, classification. Empirical methods: hypothesis, observation, experiment, description. Results. This paper defines "military capabilities" and their relationship with military potential. It has been established that the ability to use military potential (military power/strength) is a military capability. Military expenditures are used to develop capabilities in the Ministry of Defence of Ukraine's system. Thus, allocating and redistributing expenditures for the army's needs is financial support. The armed forces' financial support drives the country's economic growth. To establish this fact, the leading indicators of military expenditures in the Ministry of Defence of Ukraine (from now on – MoD) were analysed and the indicator of economic growth – gross domestic product (from now – GDP) from 2012 to 2021. This period is crucial for Ukraine's national security, defence, and economic growth, as the basic principles of state defence policy were established during this time. This motivated us to analyse financial and defence indicators to determine their interrelationship. C o n c l u s i o n s . Two variables were defined as military expenditures and the GDP, where the first variable is independent and the second is dependent. A high correlation between military spending and economic growth in Ukraine was found by constructing a scatter plot, performing the relevant calculations, obtaining the data in an ANOVA table, setting up a regression line, and conducting null hypothesis tests.

Background. An analysis of the sufficiency of the regulatory and legal support of the organization and the recruitment of citizens for military service during mobilization was conducted. It was established that the organizational and legal mechanisms for the organization and implementation of the enrollment of citizens for military service during mobilization, as well as the provision and registration of deferments to conscripts during mobilization and during wartime in the territorial recruitment and social support centers are not defined. The corresponding normative legal acts, which are necessary for the performance of tasks in the territorial recruitment and social support centers, remain undeveloped, in particular regarding the organization and conduct of proceedings in cases of administrative offenses, issuance, accounting and storage of military accounting documents. Methods . The basis of the work is the method of meaningful analysis, with the help of which the adequacy of the regulatory and legal support of the organization and the conscription of citizens for military service during mobilization was analyzed. Results . Practical recommendations for improving the regulatory and legal support for the activity of territorial recruitment and social support centers are provided, as well as the content of the procedure for organizing and conducting the enrollment of citizens for military service during mobilization is proposed. The directions of further research on the improvement of the methodology of regulatory and legal support of the activities of the territorial centers of recruitment and social support have been determined. Conclusions. The lack of organizational and legal mechanisms for holding territorial recruitment centers and social support for the enrollment of citizens for military service during mobilization and issuing deferments to conscripts for the period of mobilization and military service has been confirmed, as well as other regulatory and legal acts that need to be developed and improved to ensure activities of territorial recruitment and social support centers.

Background. The analysis of trends in land cover changes will allow to detect trends in land cover changes, which will contribute to the understanding of the reasons for changes in natural ecosystems and the development of strategies for their preservation and restoration. The analysis of land cover changes can be useful for assessing the impact of anthropogenic and natural factors on land using, which is important for making decisions about the rational using of natural resources, especially in the post-war period. The purpose of the research is to allow to detect the trends of land cover changes in Kharkiv region as a result of hostilities, using the satellite materials and statistical data from open sources. Methods. For the research, materials from remote sensing of the Earth were utilized, including methods of their processing and visualization. M a t h e m a t i c a l and statistical methods were applied to process statistical information and obtain index images resulting from the processing of satellite images and the generation of thematic raster data. The article conducts an analysis of the main trends in land cover changes in the Kharkiv region, highlighting trends for the most significantly altered land cover types, specifically forests and agricultural lands, for the period 2015-2022. Results. A general trend since 2015 has been the reduction of forested areas and agricultural lands, with a significant decrease in 2022, as a result of military actions and their consequences. Land cover degradation due to military activities is currently a prominent trend, representing the primary tendency in land cover changes. As a result of military actions in the Kharkiv region, all natural resources have suffered: lands from pollution and contamination with various types of waste, atmospheric air from emissions due to explosions and fires, water bodies, forest resources, and fauna from enemy equipment, pollution, and deliberate destruction. Conclusions. For a more detailed study of land cover changes related to military activities, especially regarding the destruction of the humus layer, soil pollution with metal fragments and explosive residues, field research and the use of high-resolution aerial or satellite imagery are necessary.

Authors: Ashrita Kovvuru , Lokesh Ethuri
Published: February 2024

Mucopolysaccharidosis (MPS) IVA, or Morquio syndrome, is a rare lysosomal storage disorder characterized by skeletal dysplasia. It is caused due to deficiency in the enzyme N-acetylgalactosamine-6-sulfatase (GALNS), which results from an autosomal recessive mutation in the GALNS gene. The frequency of this mutation is equivalent in men and women. Here in, we present the case of Morquio syndrome, in a male child of twin gestation with poor antenatal and natal history. The peculiar presentations are those of skeletal deformities, coarse facial features, recurrent respiratory tract infections, and a history of NICU admission for meconium aspiration syndrome. This case is unique because, despite a negative family and prenatal history, and one of the twins being unaffected which adds to its appeal. Later, on biochemical and radiological investigations, he was diagnosed with mucopolysaccharidoses IVA and ultimately managed him supportively.

Anemia is a very common condition in pregnancy. It represents one of the most common risk factors for maternal as well as fetal complications. Its early identification, treatment and prevention is necessary to avoid these complications.

The objective of this study was to evaluate prevalence of anemia in pregnant women attending outpatient department.

In this single center retrospective clinic-based study carried pregnant women attending for their regular ante-natal checkup were included. Demographic details, hemoglobin level and prior obstetric related history was noted. Prevalence of anemia was estimated based on the hemoglobin level. The severity of anemia was categorized as mild (Hb level 10 g/dL to 10.9 g/dL), moderate (Hb level 7 g/dL to 9.99 g/dL), severe (Hb level <7 g/dL).Corelates of anemia were examined based on the demographic parameters.

The study included 199 pregnant females with mean (SD) age was 29.6 (4.1) years. Mean (SD) hemoglobin of the study population was 10.6 (1.4) gm. A total of 174 (87.44%) females were house-makers and 165 (82.9%) were from the urban area. Anemia was observed in 76 (38.2%) pregnant females. Mild, moderate and severe anemia was observed in 32 (42.11%), 43 (56.58%) and 1 (1.3%) female respectively. Out of 76 pregnant females with anemia, 66 (86.8%) were housemakers. No significant difference was observed in the mean age (p=0.34) and body weight (p=0.69) of pregnant females with or without anemia. There was no significant difference in the anemia prevalence in rural versus urban pregnant females (p=0.33).

Prevalence of anemia in pregnant women was 38.2%. Moderate anemia was more common than mild and severe anemia. There was no significant difference in the mean age or residence of pregnant females with anemia versus without anemia.

Published: February 2024

Cervical cancer stands as the second most prevalent cancer among women in the reproductive age bracket. According to Globocan 2020, there were 604,100 newly diagnosed cases of cervical cancer worldwide, resulting in 341,831 fatalities. In India, there are 436.76 million women aged 15 and older who face the risk of developing cervical cancer.

To explore the basic knowledge of cervical cancer, its risk factors, and preventive measures among female healthcare professionals and medical students.

A cross-sectional study among all 205 female healthcare providers comprising of doctors, medical students (1st, 2nd & 3rd-year MBBS), and nurses was conducted at Gautam Buddha Chikitsa Mahavidyalaya, Jhajhra, Dehradun, in December 2023. Google Forms platform was used to conduct the pre-composed online survey. Data was entered and analyzed with SPSS software version 26.

A maximum number (141) of participants identified HPV infection as a risk factor for cervical cancer followed by multiple sexual partners (137) while 41.95% of subjects knew about early pregnancy as a risk factor for cervical cancer. Knowledge of risk factors for cervical cancer is highest among doctors followed by nurses and students. 81.95% of participants knew that cervical cancer is preventable and screening helps in the prevention of cervical cancer.

Regular upgradation of knowledge of female nursing personnel is crucial since women tend to seek advice from them more often. Similarly, HPV and cervical cancer should be strategically incorporated at the beginning of the medical curriculum.

Published: February 2024

: SARS COV-2 vaccination was a global effort to tackle the Covid-19 pandemic. During the vaccination drive, several concerns were raised about the potential adverse effects of the Covid-19 vaccines, which included the impact on menstruation and fertility in women. This study aimed to assess experiences of Indian Women with covid vaccination and its effects on their menstruation.

A prospective web-based survey was conducted targeting women aged 18years and above and who had taken atleast one dose of the covid vaccine.

: The total number of responses received were 363. After excluding those with missing details, 342 respondents were included in the analysis. The mean age of the participants was 38.02 ± 7.8 years. 68.1% of the respondents (233/342) reported no change in the periodicity of their cycles post vaccination and 79.5% (272/342) reported no change in the menstrual flow. Forty three women (12.6%) reported experiencing heavy flow post vaccination. In this group which experienced heavy menses, 81.5% (35/43) reported that the heavy menses was self-limiting and did not require any treatment. 9.3% (4/43) of these symptomatic women recorded that short term treatment was sought. Another 9.3% of women reported persisting menstrual changes, at the time of the survey, despite taking prescribed treatment. It was also noted that the changes in menstrual cycles were significantly more in vaccinated nulliparous women.

: Covid vaccination appears to have no or little impact on menstrual cycles in two-thirds of the women taking the vaccine. 31.9% of the women in the survey reported some change in their menstrual timing or flow. Most changes were self -limiting. About 1% (4/342) may have longer standing menstrual impact, requiring treatment.

Authors: Tayal Nikhil , Ramu Gopi , Gupta Rajkumar
Published: February 2024

Abdominal pain is a very common complaint during pregnancy, which can be because of a number of causes including surgical, non-surgical and pregnancy related factors. A rare cause of abdominal pain is adrenal haemorrhage, which can be traumatic as well as spontaneous. The exact incidence of spontaneous adrenal haemorrhage in pregnancy is not known, however various autopsy series have shown it to be 0.3-1.8% in general population. We present a case report of 27 year female with pain abdomen. On further evaluation, she was found to have left adrenal lesion for which she underwent left sided adrenalectomy. Common causes of adrenal haemorrhage include trauma, stress like surgery, sepsis, burns, pregnancy, anticoagulation or coagulopathy. Spontaneous adrenal haemorrhage is a rare diagnosis in pregnancy and a high degree of suspicion is needed for diagnosis. A preoperative diagnosis of adrenal hematoma is difficult to make and is usually made postoperatively.

Published: February 2024

Herlyn Werner Wunderlich syndrome is a very rare congenital anomaly of the urogenital tract involving Mullerian ducts and mesonephric ducts. It is synonymous with OHIVRA syndrome which is Obstructed Hemivagina with Ipsilateral Renal Agenesis syndrome. Very few case reports have been reported regarding the syndrome. Herein, we report a case of 20 year old unmarried female with unusual presentation of OHVIRA syndrome with complaints of spotting per vagina and with vaginal cyst on examination. Diagnosis was confirmed by MRI which showed features of OHVIRA with pyometra caused by the obstructed hemivagina. She was managed surgically by diagnostic laparoscopy and per vaginal resection of the vaginal septum and drainage of around 50cc of pyometra followed by visualisation of two separate cervical canals post procedure. As a rare entity, a high degree of clinical suspicion is necessary to diagnose and intervene at the right time to ensure optimum results and prevent complications and preserve fertility.
Placenta percreta in first trimester – A rarity and diagnostic dilemma

Published: February 2024

The diagnosis of placenta accreta spectrum (PAS) in pregnancy is associated with severe maternal complications and is potentially life threatening. Moreover, PAS is difficult to diagnose in the first trimester, and the accuracy is low. A prenatal diagnosis is pivotal for planning an optimal management in PAS. A first trimester US(Ultrasound) can detect PAS in good proportion of cases, although the sensitivity is lower than a second or third trimester US. An early first trimester US can further help predict severity of PAS and its surgical outcome. As the management and diagnosis remains a challenge as far as PAS in early pregnancy is concerned, a high clinical suspicion especially in cases of previous uterine scar and bleeding following a surgical evacuation cannot be overemphasised. We report a case of Placenta Percreta in First Trimester, its rarity and diagnostic dilemma.
Haemoglobin lepore and beta thalassaemia traits – Prenatal testing by both sequence analysis and MLPA for HBB gene: A case report
Authors: Mukhopadhyay Saswati
Published: February 2024

Hb Lepore is a fusion globin protein made of fused chains of delta and beta globin. It is a deletion haemoglobinopathy. In homozygote form, it is similar to transfusion dependent beta thalassaemia major, and in the heterozygous form, it causes mild microcytic hypochromic anaemia. In this case report, the couple has heterozygous Hb Lepore and heterozygous beta thalassaemia, with a pregnancy of 15weeks gestation. Prenatal testing by amniocentesis and HBB gene analysis for the fetus was done by sequencing and MLPA to detect the different types of mutations present in the parents. This case report reveals the importance of MLPA to be done along with sanger sequencing, to detect all types of mutations in the HBB gene.

Key to a successful outcome in a rare life threatening condition like cesarean scar ectopic pregnancy is early diagnosis and treatment. The risk of massive haemorrhage can lead inevitably to a hysterectomy in past. The most effective method of treatment is not yet found. We report a case of a previous LCSC and one D& E of 35-year-old female (G3P1A1L1) with 7 weeks of amenorrhea and vaginal bleeding. A gestational sac with an embryo in the cesarean scar canal was seen on ultrasonography. The fertility-sparing therapeutic strategy involved cesarean scar curettage to remove the trophoblastic under ultrasound.

: To report a case series on corneal trauma induced by forceps assisted vaginal delivery.

: Case records of six patients who had clinical features suggestive of corneal trauma induced by forceps delivery were retrospectively reviewed and analysed.

Vertical to oblique corneal Descemet’s membrane (DM) tears were noted in all 6 patients which included 2 males and 4 females. Right eye was involved in all patients and one patient had bilateral involvement. The age of presentation ranged from 5 to 39 years. Three patients had visual acuity better than 6/18 and three had worse than 6/18 in their affected eyes. All patients had corneal astigmatism in the range of 1.75 to 8 diopters.

: A complicated vaginal delivery should be anticipated at the earliest by the obstetrician and an apt decision on the mode of delivery has to be attempted in order to prevent avoidable ocular trauma, especially in forceps assisted vaginal deliveries. All neonates who are born by forceps assisted vaginal delivery require mandatory referral to an ophthalmologist to rule out any ocular trauma. Early intervention can prevent irreversible vision loss due to amblyopia.

In addition to having a busy course in college, some students also have activities outside of college; have a job. Dense lecture activities and busy work carried out can cause work-study conflicts in students. Work-study conflict is a work activity that interferes with student learning activities to meet demands and obligations related to school or campus. One of the factors that can reduce work-study conflict is resilience. The purpose of this study was to determine the relationship between resilience and work-study conflict. This study used quantitative methods with a correlation approach. The data collection procedure uses a nonprobability sampling technique of accidental sampling type with a sample of 170 people collected using google research form. The research measurement tool used the Work Study Conflict Scale (WSCS) with Alpha Croanbach (α) 0.777 and the Connor Davidson Resilience Scale (CD-RISC) with Alpha Croanbach (α) 0.930. The hypothesis test was carried out using the Spearman Correlation technique, obtaining a significance value (p) = 0.471 (p<0.05). The results showed there is no negative relationship between resilience and work-study conflict in working students. In addition, the results also showed that the majority of research subjects were in the high work-study conflict category and the high resilience category.

The purpose of the study was to determine the relationship between corporate misconduct announcements and share prices. The study employed an event study methodology where data was collected from a sample of 30 companies that were listed on the Johannesburg Stock Exchange (JSE). Data collected spanned a period of ten years, from 2011 to 2020. The study’s findings demonstrate that there is no significant relationship between announced incidents of ethical misconduct by JSE-listed companies and the returns of the underlying shares. Previous studies of a similar nature have asserted that the announced ethical misconduct of a company has a significantly negative effect on its share price. The study considers the dynamics that exist between principals (shareholders) and their agents (directors), who are charged with the governance of listed companies. It considers the morality of the actions taken by agents in governing organisations and the implications for the equity returns of principals. Contrary to the previous studies and studies in other countries, analysed results imply that equity holders of JSE-listed companies do not significantly punish companies that have incidents of ethical misconduct that are announced. The study’s findings have practical implications for the JSE and its requirements for disclosure of ethical issues to firm principals.

This paper investigates the dynamic conditional correlations and volatility spillovers between global stock markets and international green bonds. Envisaging the linkages between the emerging green bond markets and global equities given the unforeseen global pandemic. We use R software to run bivariate VAR-BEKK GARCH and BEKK GARCH models to investigate the time-varying conditional volatility between global stock indices and green bond indices. Daily prices of all variables from October 2014 to April 2023 are sourced from the Bloomberg database. The short-term influence of past events, as well as the long-term persistence of green bonds, on the current conditional volatility of global equity indices of developed and emerging economies is observed. Whereas from equity markets to green bond indices, the short-term as well as long-term impact is confined to only 2-3 indices. The results provide future direction for policymakers, researchers, and global investors in hedging and creating an optimal portfolio.

The purpose of this study is to investigate the effect of various leadership styles on employee performance in the Fast-Moving Consumer Goods (FMCG) industry in China. The unexpected global spread of the coronavirus pandemic and its complicated issues have created a substantial amount of uncertainty in consumer demand worldwide which has motivated this research and highlighted the crucial role that the FMCG industry's marketing relationship plays in determining enterprise profit. There is a growing concern among enterprise managers, academics and policymakers about employee performance and its overarching impact on the organization. The study is underpinned by social exchange theory and employs a cross-sectional design. An online survey was conducted with 384 employees from the FMCG industry to measure the impact of three independent variables: authentic leadership style, servant leadership style   and ethical leadership style. The findings reveal that authentic, servant and ethical leadership all significantly affect employee performance in the Chinese FMCG industry. Among these, ethical leadership is found to have the extreme effect. The implications of this study are of practical relevance to FMCG companies. FMCG companies can potentially navigate through the uncertainty in global consumer demand more effectively by reconfiguring their leadership styles to enhance employee performance. The study provides insights that can be used by FMCG companies to increase employee performance   which is directly linked to enterprise profit.
