ABSTRACT Background: Anemia during pregnancy is a global health issue affecting nearly 50% of pregnant women worldwide. In Indonesia, the increasing prevalence of anemia reflects a persistent public health challenge. One contributing factor is poor adherence to iron tablet (Fe) supplementation. This study aimed to determine the relationship between compliance with iron tablet consumption and the incidence of iron deficiency anemia in pregnant women at the Sei Langkai Public Health Center. Methods: This was a quantitative study using a cross-sectional design. The sampling technique was accidental sampling with a total of 56 pregnant women. Data were collected through questionnaires and hemoglobin levels were measured using the Easy Touch device. Data analysis was performed using the Chi-Square test. Results: The Chi-Square test showed a significant relationship between compliance with iron tablet intake and the incidence of iron deficiency anemia (p = 0.001). Conclusion: There is a significant relationship between iron tablet compliance and the incidence of iron deficiency anemia in pregnant women at the Sei Langkai Public Health Center.

Background: The mountain communities of the Pakistani Himalayas possess rich ethnobotanical traditions centered around high-value medicinal plants such as Trillium govanianum Wall. ex D. Don, Dactylorhiza hatagirea (D. Don) Soo, Aconitum heterophyllum Wall. ex Royle, and Podophyllum hexandrum Royle. These species play vital roles in local health care, livelihoods, and cultural identity. Despite this significance, systematic documentation is limited, posing risks to both traditional ecological knowledge (TEK) and biodiversity conservation. Methods: From May 2024 to June 2025, an ethnobotanical survey was conducted across 24 mountain villages in Azad Jammu and Kashmir (Neelum, Leepa, and Hattian) and Khyber Pakhtunkhwa (Kaghan, Siran, and Galliat), at altitudes of 2,000–3,300 m. Using purposive and snowball sampling, A total of 120 respondents were engaged, including 98 household respondents and 22 key informants (10 forestry officers and 12 herbal traders) interviews were completed. Field observations and gender-segregated focus groups provided complementary insights into plant use, harvesting practices, and trade. Voucher specimens were authenticated at the Pakistan Museum of Natural History. Data were analyzed thematically for TEK, gender, and governance dynamics, alongside quantitative summaries of market dependence. Results: Community governance structures revealed extensive reliance on TEK for species identification, collection timing, and sustainable use. However, weak institutional enforcement and rising market demand threaten traditional management systems. Conclusions: Integrating indigenous knowledge and women’s participation into formal conservation and livelihood policies is essential for safeguarding both cultural resilience and Himalayan biodiversity.

This study investigates the determinants of entrepreneurial mindset among university students by examining intrinsic motivation, self-efficacy, and financial literacy, with financial literacy as a moderating variable. Using a quantitative approach and PLS-SEM (Smart-PLS), data were collected from 81 undergraduate students who had completed introductory accounting, financial management, or entrepreneurship courses. The measurement model demonstrates satisfactory reliability and validity. The structural results show that intrinsic motivation and self-efficacy do not have a significant direct effect on entrepreneurial mindset, while financial literacy has a strong positive influence. Financial literacy significantly moderates the relationship between intrinsic motivation and entrepreneurial mindset but does not moderate the effect of self-efficacy. The model explains 93.8% of the variance in entrepreneurial mindset. The findings emphasize the importance of financial literacy and support effectuation-based entrepreneurship education.

Rock fragmentation is a key determinant of downstream excavation performance in surface mining operations. Among blasting design parameters, stemming depth governs explosive energy confinement; however, its field-scale influence on fragmentation quality and excavation efficiency remains insufficiently quantified. This study experimentally investigates the effect of two stemming depths (3 m and 4 m) on rock fragmentation characteristics and excavator cycle time through controlled field blasting trials conducted in a hard sandstone formation. All blasts were executed using identical drilling geometry, explosive type, and operational procedures, with stemming depth treated as the sole variable. Fragmentation outcomes were quantified using image-based analysis (Split Desktop), while excavator cycle time and its individual components were measured directly during loading operations. Statistical evaluation was performed using descriptive statistics, Mann–Whitney U tests, and one-way analysis of variance (ANOVA). The results show that a 3 m stemming depth produces consistently finer fragmentation, reflected by a lower median fragment size (D50 = 38.1 cm) compared to the 4 m configuration (D50 = 45.6 cm), along with a substantial reduction in oversize fragments (> 50 cm) from 27.9% to 12.4%. Improved fragmentation is associated with a statistically significant reduction in excavator digging time for 3 m stemming (14.2 ± 2.1 s) relative to 4 m stemming (18.6 ± 3.0 s; p = 0.004). In contrast, no statistically significant difference is observed in the mean total excavator cycle time between the two configurations. These findings are limited to a single lithology and blast geometry and should therefore be regarded as conditionally applicable to comparable geological and operational settings. Nevertheless, the study demonstrates that appropriate stemming depth selection can reduce oversize generation and improve excavation smoothness, providing practical, field-based guidance for blast design optimization. Field-scale blasting experiments demonstrate that reducing stemming depth from 4 m to 3 m significantly improves rock fragmentation quality in hard sandstone. A 3 m stemming depth decreases median fragment size (D50) from 45.6 cm to 38.1 cm and reduces oversize fragments (> 50 cm) from 27.9% to 12.4%. Improved fragmentation results in a statistically significant reduction in excavator digging time (from 18.6 ± 3.0 s to 14.2 ± 2.1 s; Mann–Whitney p = 0.004). No statistically significant difference is observed in mean total excavator cycle time, indicating that operational benefits are expressed through reduced variability and smoother excavation rather than faster average cycles. The findings provide site-specific, field-based evidence supporting stemming depth selection as a practical control parameter for improving excavation performance.

Main Purpose – This study examines the evolution of the Balanced Scorecard (BSC) into the Sustainability Balanced Scorecard (SBSC) and proposes a Resilience-Oriented SBSC (R-SBSC) that integrates sustainability performance, risk governance, and organisational adaptability.Method - A systematic literature review (SLR), guided by the PRISMA framework, was conducted on 41 SBSC-related articles published between 2020-2025. A thematic synthesis was applied to trace conceptual developments, sectoral trends, implementation patterns, and the ways resilience elements are incorporated into SBSC designs.Main Findings - The review shows a clear shift from the traditional BSC toward more contextual SBSC variants, including ESG-focused, health-inclusive, and circular SBSC models. Empirical evidence indicates improvements in strategic alignment, stakeholder trust, and sustainability performance. However, persistent challenges remain, particularly the complexity of SBSC design, indicator proliferation, and the limited explicit integration of resilience capabilities.Theory and Practical Implications - The proposed R-SBSC embeds adaptive capacity and risk intelligence within the SBSC cause–effect logic. It contributes to the development of dynamic capabilities and sustainability governance perspectives, while offering actionable guidance for managers to incorporate resilience considerations into sustainability performance management.Novelty - This study reframes the SBSC as a resilience-oriented management system through the R-SBSC model, positioning the SBSC not merely as a sustainability reporting tool but as an integrated framework for sustainability, risk, and organisational adaptation.

Background: Myxedema crisis, which occurs due to hypothyroidism, is a rare and life-threatening condition that can lead to severe myocardial infarction and lethal arrhythmia, as presented in this case. Case Presentation: A 63-year-old man presented with typical prolonged chest pain, palpitations leading to near syncope, severe fatigue, loss of appetite, dizziness, and somnolence 2 days before admission. The patient exhibited somnolence, hypotension, thin eyebrows, and pretibial pitting edema. Electrocardiography revealed sinus rhythm with a prolonged QT interval, inferolateral-anterior ischemia, and a troponin-T value five times above the upper limit of normal. Therefore, the working diagnosis included non–ST-elevation myocardial infarction Killip IV, severe biventricular heart failure, severe acute kidney injury, and severe acute liver injury. On the third day of treatment, the patient experienced two consecutive episodes of unstable ventricular tachycardia and one episode of return of spontaneous circulation cardiac arrest. Thyroid examination incidentally revealed severe hypothyroidism with severe hyperkalemia. After other causes were excluded, the diagnosis of myxedema crisis was assumed. Oral thyroid therapy, levothyroxine (100 µg once daily), was administered. Within 3 days of initiating all treatments, the patient experienced significant hemodynamic improvement, improved kidney function, and normalization of liver function, accompanied by the disappearance of dyspnea, chest pain, and edema, with a compos mentis status. The patient was discharged with stable hemodynamics without support on the tenth day of treatment and underwent a coronary computed tomography angiography at an outpatient facility, which showed near-normal coronary results. The patient has been on routine follow-up for almost 1 year with levothyroxine (50 µg once daily) and has recently demonstrated good left ventricular function (ejection fraction=50%) and good functional capacity on an exercise test. Conclusion: Clinicians should consider hypothyroidism crisis in the differential diagnosis for myocardial infarction, heart failure, and lethal arrhythmia, and treatment should be initiated immediately.

The Airbus A320 has two main engines and an Auxiliary Power Unit (APU) that generate high-temperature, high-pressure bleed air used for cabin cooling, anti-icing, and pressurization. Two temperature sensors, Fire Loop A and Fire Loop B, monitor the bleed air distribution line for hot air leaks. An Air Bleed Maintenance Message signals a malfunction in these fire protection loops and requires quick maintenance to avoid system failure. Leaks, especially near the wing and fuel tank, pose significant hazards. This study uses Fault Tree Analysis (FTA) to find the root causes of this message. The main causes identified are damaged interconnecting cables, failure in the Bleed Monitoring Computer (BMC), and faults in Fire Loop A or B. The FTA diagram helps technicians trace each component's role in the failure, aiding efficient inspection and maintenance. This method aims to boost system reliability and improve flight safety.
