A quasi-experimental study to evaluate the effectiveness of a structured teaching programme on knowledge regarding dysmenorrhea among adolescent girls at selected schools in Madurai district
Authors: Israel M Priyanka , Priscilla K 
Published: January 2024

Adolescence is indeed a transitional phase of growth and development that occurs between childhood and adulthood, typically spanning from 10 to 19 years of age, as defined by the World Health Organization (WHO). During this period, individuals undergo rapid physical, cognitive, and psychosocial changes, which can influence their emotions, thoughts, decision-making abilities, and interactions with the world. It is worth noting that psychological factors, including anxiety and anger, may contribute to dysmenorrheal problems, which are painful menstrual cramps. However, as women age, dysmenorrheal often decreases and may completely resolve after childbirth. The study aims to assess the effectiveness of a structured teaching program in improving knowledge about dysmenorrhea among adolescent girls. By implementing this program, researchers seek to measure the impact it has on enhancing the understanding and awareness of dysmenorrhea among this specific population. The evaluation will provide valuable insights into the effectiveness of structured teaching in improving knowledge about dysmenorrhea among adolescent girls.In a quasi-experimental research study conducted in the Madurai district, a one-group pre-test and post-test design was utilized. A simple random sample of 40 adolescent girls participated in the study. A structured teaching program was implemented, covering all aspects of dysmenorrhea. The knowledge of the adolescent girls was assessed both immediately before and a week after the structured teaching program. The results of the study indicated that the majority of the adolescent girls (47%) were 14 years old, and a significant proportion (62%) had no prior information about dysmenorrhea. In the pre-test, all of the adolescent girls (100%) demonstrated inadequate knowledge regarding dysmenorrhea. However, in the post-test, 80% of the participants showed adequate knowledge, while 20% had moderate knowledge on the subject. The paired t-test analysis revealed a statistically significant improvement in knowledge from the pre-test (10.3 ± 2.87) to the post-test (41.17 ± 8.75) (p &#60; 0.05), indicating that the structured teaching program was effective in enhancing knowledge about dysmenorrhea among the adolescent girls in the study. The present study concludes that recently dysmenorrhea is a quite common problem all over the world affecting the quality of life of women significantly. Despite the growing awareness, there remains a considerable deﬁciency of knowledge on causes, treatment, and home remedies of dysmenorrhea. Further research is required for a large population including women from various backgrounds to better assess and strategize to manage this rising problem. It will help future mothers to take care of them during menstruation, and they will educate the future generation regarding dysmenorrhea.
Education of special children within the scope of custody rights in the Turkish civil code
Authors: Canarslan Gokce 
Published: January 2024

The education of the child is both a right and an obligation for the mother and father who have the right of custody. For this reason, when exercising parental authority, the best interests of the child should be prioritized. Provisions regarding the education of children are regulated in the second book of the Turkish Civil Code titled Family Law, in the sixth section titled Custody under the second subsection titled Kinship. This study aims to discuss the education of special children within the scope of custody rights according to the Turkish civil code. The legislation has introduced a clear regulation to ensure that the educational rights of children with special education needs are not violated, even by the parents who have custody rights. The Turkish Civil Code reveals that when parents exercise their right of custody, which is both a right and an obligation, they must take into account the principle of protecting the interests of the children, and that the care and education of the children must be carried out with the decision taken in the light of this principle.

It has been shown that rotundone, the only identified aroma compound imparting peppery notes in red wine, was neutrally or positively perceived by consumers, except for young non-anosmic respondents who disliked it. This work aimed to explore the main negative driver of liking for this target of consumers in a peppery Duras red wine from a cool and wet season and for which other penalties might apply. A convenience panel of one-hundred and thirty-four young French consumers from Ecole d’Ingénieurs de Purpan in Toulouse (18–24 years) was recruited for the study. Panellists were asked to rate their overall liking on a 9-point hedonic scale of such wine and their perception of seven sensory attributes on a 5-point just-about-right (JAR) scale, with 3 corresponding to the central just-about-right word anchor. Results from penalty analysis demonstrated that a lack of fruity notes followed by an excessive sourness and an excessive intensity of peppery notes were the main penalising sensory characteristics. The findings, that are still preliminary and would deserve to be confirmed using a panel composed of young consumers with other social and cultural background, highlight that the intensity of peppery notes was not the main negative driver of young consumers’ liking of Duras wine produced during a vintage year with unfavourable cool and rainy climate conditions. However, the results of this study encourage Duras producers targeting such consumers to propose a wine exhibiting a good balance between fruity and peppery notes and a moderate acidity level that could be achieved during such season through deacidification. This research is a good illustration of the fact that the penalty analysis method can be implemented on a single wine sample.

Authors: Meyer Manuel de Figueiredo , Gonçalves José Alberto , Bio Ana Maria Ferreira 
Published: January 2024

This study assesses the applicability of different-resolution multispectral remote sensing images for mapping and estimating the aboveground biomass (AGB) of Carpobrotus edulis, a prominent invasive species in European coastal areas. The performance of three sets of multispectral images with different resolutions was compared: (i) 2.5 cm Ground Sample Distance (GSD), 5 cm GSD and 10 cm GSD images. The images were classified using the supervised classification algorithm Random Forest and later improved applying a sieve filter. The results show that the three tested image resolutions allow constructing reliable coverage maps of C. edulis, with Overall Accuracy values of 89%, 85% and 88% for the classification of the 2.5 cm, 5 cm and 10 cm GSD images, respectively. Samples were also collected, dried and weighed to estimate AGB using the relationship between the Dry Weight and Vegetation Indices (VI). The regressions were evaluated based on their R² and Normalised RMSE. The best-performing VI-DW regression models achieved: R² = 0.87 and NRMSE = 0.09 for the 2.5 cm resolution; R² = 0.77 and NRMSE = 0.12 for the 5 cm resolution; and, R² = 0.64 and NRMSE = 0.15 for the 10 cm resolution. C. edulis area and total AGB were: 3441.10 m² and 28,327.1 kg (with a Relative Error (RE) = 0.08), for the 2.5 cm resolution; 3070.04 m² and 29,170.8 kg (RE = 0.08), for the 5 cm resolution; and, 2305.06 m² and 22,135.7 kg (RE = 0.11), for the 10 cm resolution. Differences were analysed in detail, spatially, to determine their causes. Final analyses suggest that, for C. edulis, multispectral imagery of up to 5 cm GSD is adequate for the estimation of the species’ distribution and biomass.

Objectives. To assess COVID-19 vaccination rates among North Dakota residents who gave birth. Methods. We used data from North Dakota Vital Records and the North Dakota Immunization Information System for North Dakota residents who gave birth between April 1, 2021, and July 15, 2022. We evaluated vaccination with 1 dose, primary series, and monovalent booster for timing before and during pregnancy and postpartum. Results. Among North Dakota residents who gave birth, 44% received at least 1 COVID-19 vaccine, 34% received a complete primary series, and 10% received a monovalent booster dose. Among those who received a COVID-19 vaccine, the majority was vaccinated during pregnancy. Obstetrics and gynecology providers administered just 9.2% of COVID-19 vaccine doses. Conclusions. Most persons who gave birth in North Dakota did not receive the primary series of the COVID-19 vaccine while pregnant. Providers have an opportunity to counsel their pregnant and recently pregnant patients on vaccine recommendations.

Summary
The injection of carbon dioxide (CO2) into coal seams is a prominent technique that can provide carbon sequestration in addition to enhancing coalbed methane extraction. However, CO2 injection into the coal seams can alter the coal strength properties and their long-term integrity. In this work, the strength alteration of coals induced by CO2 exposure was modeled using 147 laboratory-measured unconfined compressive strength (UCS) data points and considering CO2 saturation pressure, CO2 interaction temperature, CO2 interaction time, and coal rank as input variables. Advanced white-box and black-box machine learning algorithms including Gaussian process regression (GPR) with rational quadratic kernel, extreme gradient boosting (XGBoost), categorical boosting (CatBoost), adaptive boosting decision tree (AdaBoost-DT), multivariate adaptive regression splines (MARS), K-nearest neighbor (KNN), gene expression programming (GEP), and group method of data handling (GMDH) were used in the modeling process. The results demonstrated that GPR-Rational Quadratic provided the most accurate estimates of UCS of coals having 3.53%, 3.62%, and 3.55% for the average absolute percent relative error (AAPRE) values of the train, test, and total data sets, respectively. Also, the overall determination coefficient (R2) value of 0.9979 was additional proof of the excellent accuracy of this model compared with other models. Moreover, the first mathematical correlations to estimate the change in coal strength induced by CO2 exposure were established in this work by the GMDH and GEP algorithms with acceptable accuracy. Sensitivity analysis revealed that the Spearman correlation coefficient shows the relative importance of the input parameters on the coal strength better than the Pearson correlation coefficient. Among the inputs, coal rank had the greatest influence on the coal strength (strong nonlinear relationship) based on the Spearman correlation coefficient. After that, CO2 interaction time and CO2 saturation pressure have shown relatively strong nonlinear relationships with model output, respectively. The CO2 interaction temperature had the smallest impact on coal strength alteration induced by CO2 exposure based on both Pearson and Spearman correlation coefficients. Finally, the leverage technique revealed that the laboratory database used for modeling CO2-induced strength alteration of coals was highly reliable, and the suggested GPR-Rational Quadratic model and GMDH correlation could be applied for predicting the UCS of coals exposed to CO2 with high statistical accuracy and reliability.
Speciation characterization and environmental stability of arsenic in arsenic-containing copper slag tailing
Authors: You Mu , Hu Yunhu , Zhou Chuncai 
Published: January 2024

Abstract
The increasing presence of arsenic-containing impurities within Cu ores can adversely affect the smelting process and aggravate the environmental impact of slag tailing. This study investigates the geochemical, mineralogical, and chemical speciation characteristics to better understand the association and environmental stability of metal(loid)s in copper slag tailing. The results indicate that the predominant chemical compositions of the selected slag tailing are Fe2O3 (54.8%) and SiO2 (28.1%). These tailings exhibit potential for multi-elemental contamination due to elevated concentrations of environmentally sensitive elements. Mineral phases identified within the slag tailings include silicate (fayalite), oxides (magnetite and hematite), and sulfides (galena, sphalerite, arsenopyrite, and chalcopyrite). The consistent presence of silicate, iron, arsenic, and oxygen in the elemental distribution suggests the existence of arsenic within silicate minerals in the form of Si-Fe-As-O phases. Additionally, arsenic shows association with sulfide minerals and oxides. The percentages of arsenite (As(III)) and arsenate (As(V)) within the selected slag tailings are 59.4% and 40.6%, respectively. While the slag tailings are deemed non-hazardous due to the minimal amounts of toxic elements in leachates, proper disposal measures should be taken due to the elevated carbonate-bound levels of As and Cu present in these tailings.

Published: January 2024

Abstract
The metabolic syndrome (MeTS) negatively affects male sexual function. Lifestyle changes improve erectile function. However, the effects of lifestyle changes on sexual function in men with and without MeTS on the visceral adiposity index (VAI) have not been adequately investigated. Patients with MeTS (n = 48) and those with no MeTS (n = 31) were recruited. Sexual functions and psychogenic status were assessed using the International Index of Erectile Dysfunction (IIEF) questionnaire and Beck’s depression inventory (BDI), respectively. The VAI was calculated using the gender-specific formula. Demographic, clinical, biochemical and hormonal data were recorded. Participants were advised to 8500 steps per day and dietary control. At least three months later, demographic and biochemical tests were repeated, and the VAI was calculated. Association between sexual functions, presence of MeTS and lifestyle changes via the VAI were analyzed. Each integer increase of the VAI was related to a 1.74-fold increased risk of ED in the MeTS group. The MeTS was related to moderate to severe ED than those with no MeTS (p = 0.033). A 24% decrease of the VAI was recorded in the MeTS group at the end of the study (p = 0.014). The MeTS criteria were disappeared in eight patients at the end of the study, with a slight decrease of VAI (p = 0.07). In the beginning, patients with MeTS and no-MeTS showed similar sexual satisfaction, orgasm, desire, and general satisfaction scores. Sexual satisfaction, orgasm and general satisfaction were improved in the non-MeTS group (p < 0.05). At the end of the study, the MeTS group showed similar sexual satisfaction, desire, orgasm and general satisfaction rates (p > 0.05). Higher VAI levels were related to the lower erectile function scores, particularly in patients with MeTS. Lifestyle changes improved male sexual function scores only in the non-MeTS group. Therefore, fighting against MeTS should be adopted as a global healthcare policy.

Abstract
Background
Vaccination of healthcare workers (HCWs) is pivotal to decrease the incidence of contagious infections in hospital settings. Herein, we assessed the knowledge, attitude, and practice regarding HCWs’ recommended vaccines among medical students and interns in Egypt.
Methods
A multicenter, cross-sectional study was conducted using a structured, pilot-tested, self-administered questionnaire among Egyptian medical students and interns. We invited 1332 participants to our survey using a systematic random sampling that included participants across nine medical schools in Egypt during the 2021–2022 academic year.
Result
Out of 1332 participants, 1141 completed our questionnaire with a response rate of 85.7%. Overall, 43% of our participants knew 2–3 HCWs recommended vaccines. Furthermore, 36.7% had received a booster dose of at least one of the HCWs’ recommended vaccines in the last 10 years with only 6.1% having received all recommended vaccines. Hepatitis B vaccine was the most widely known (71%) and received (66.7%). Interns were more likely to know, receive, and recommend HCWs’ recommended vaccines. The majority (> 90%) agreed that vaccination is beneficial and safe, with a median score of eight (interquartile range [IQR]: 2) out of ten concerning vaccine efficacy and eight (IQR: 1) for safety. However, the median score for hesitancy was five (IQR: 5). The most common influential and limiting factors for taking vaccines were scientific facts (60.1%) and fear of vaccine side effects (44.9%), respectively.
Conclusion
Although medical students in Egypt have good knowledge and attitudes toward vaccinations, there is a gap in their practices. Interventions are needed to improve the uptake of vaccinations among medical students in Egypt.
Concerning Trends in the Mental Health of Emerging Adults: 2011 to 2022

Published: January 2024

Abstract
Importance: There is a critical need to understand changes in the mental health of emerging adults. This study focused on identifying when and among who changes in the quality of life of US adults occurred between 2011 and 2022.
Objective: To identify changes in mental and physical health-related quality of life among adults by age cohort in the United States between 2011 and 2022.
Design: This was a survey-based observational study that included annual cohorts of more than 400,000 adults living in the United States between 2011 and 2022. Data was sourced from the US Centers for Disease Control and Prevention Behavioral Risk Factor Surveillance System, a national telephone-based health survey.
Setting: This study leveraged a large population-based sample living in the United States. The sample includes data from all 50 US states, the District of Columbia and three US territories.
Participants: Data were weighted based on age, sex, ethnicity, geographic regions within states, marital status, education level, home ownership, and type of phone ownership to represent the United States population.
Main Outcome(s) and Measure(s): The primary measures included the CDC Healthy Days items, which measure the number of mentally and physically unhealthy days experienced by survey respondents in the previous 30 days.
Results: The annual sample size ranged from N=438,693 to N=506,467. An 82% increase in the number of mentally unhealthy days was observed among adults aged 18-24 between 2011 (M=4.19, 95% CI 4.03-4.35) and 2022 (M=7.61, 95% CI = 7.41-7.82), with evidence of smaller but increasing rates among adults through mid-life. Minimal changes in physically unhealthy days were observed for all age groups over the same period.
Conclusions and Relevance: This study identified a clear need to address the mechanisms underlying a dramatic increase in mentally unhealthy days among young adults, which is also becoming increasingly common in mid-life. Special attention should be paid to the role social media plays in the way people perceive, interpret, and cope with stressors or traumatic events.
