Abstract

General Background: Labor unions advocate workers’ rights and welfare through structured communication and socialization activities that foster awareness and collective engagement. Specific Background: At PT Indal Steel Pipe, Gresik Regency, the labor union conducts socialization programs to encourage employee participation despite relatively low membership involvement. Knowledge Gap: Empirical insight remains limited regarding integrated organizational communication approaches used by company-based labor unions to address participation barriers. Aims: This study examines communication strategies applied by the labor union to promote unionization among employees. Results: Using a qualitative case study with interviews, observations, and documentation, the findings show that the union implements formal socialization through structured education and informal engagement through interpersonal and persuasive dialogue, supported by written, oral, and electronic communication channels. Transparency, management support, and employee trust support participation, while scheduling conflicts, apathy, stigma, and individualistic workplace culture remain challenges. These barriers are addressed through unit-based representatives and digital communication platforms. Novelty: The study presents an integrated model combining macro and micro organizational communication networks with formal and informal approaches in an industrial union context. Implications: The findings offer guidance for strengthening union communication capacity and organizational literacy to support sustainable employee participation in collective representation. Highlights: Structured Socialization and Interpersonal Dialogue Form Complementary Engagement Mechanisms. Transparency, Managerial Support, and Trust Facilitate Membership Involvement. Scheduling Conflicts, Stigma Concerns, and Individualistic Workplace Culture Restrict Organizational Engagement.

Abstract

General Background: Adversity quotient represents students’ capacity to confront academic challenges and persist in learning tasks. Specific Background: In junior high schools, variations in students’ adversity quotient are closely associated with psychological factors, particularly self efficacy. Knowledge Gap: Previous studies predominantly focused on senior high school populations, leaving limited evidence regarding junior high school contexts. Aims: This study aimed to examine the relationship between self efficacy and adversity quotient among students at SMP X Sidoarjo using a quantitative correlational approach. Results: Data from 131 students revealed that most participants were in the moderate category for both self efficacy (72%) and adversity quotient (70%). Simple linear regression indicated a significant positive relationship (β = 0.378; p < 0.05), with self efficacy accounting for 51.3% of the variance in adversity quotient. Novelty: This research provides empirical evidence from a junior high school setting supported by preliminary field observations, extending existing findings predominantly derived from SMA/SMK populations. Implications: The findings highlight the importance of strengthening students’ self efficacy through counseling services, guidance programs, and supportive learning environments to foster higher adversity quotient and academic resilience. Keywords: Self Efficacy, Adversity Quotient, Junior High Students, Educational Psychology, Learning Resilience Key Findings Highlights: Most students demonstrated moderate psychological readiness in facing academic difficulties. Regression analysis confirmed a strong positive statistical association between personal confidence and resilience. Self-belief explained over half of students’ persistence capacity, with remaining variance linked to external factors.

Abstract

General Background: Ischemic heart disease (IHD) remains a major global health burden, primarily driven by atherosclerosis, thrombosis, and chronic inflammation. Specific Background: Emerging evidence implicates amino acid metabolism, particularly the tryptophan (Trp)–kynurenine pathway, in cardiovascular pathogenesis through its interplay with inflammation and energy homeostasis. Knowledge Gap: While the kynurenine pathway has been linked to cardiovascular disease, the specific role of Trp degradation in IHD, especially regarding NAD+ metabolism and SIRT1 regulation, is not well established. Aims: This study examined the association between Trp catabolism, NAD+ availability, SIRT1 expression, and inflammatory markers in IHD patients. Results: Compared with healthy controls, IHD patients exhibited significantly reduced serum Trp and NAD+ levels, while SIRT1 expression was markedly elevated. In parallel, inflammatory markers including CRP and Troponin were consistently higher across myocardial infarction, angina, and heart failure groups. Novelty: These findings highlight a distinct metabolic-inflammatory axis in IHD, where enhanced Trp degradation coincides with disrupted NAD+ homeostasis and compensatory SIRT1 elevation. Implications: Targeting Trp metabolism, NAD+ pathways, and SIRT1 regulation may offer novel diagnostic biomarkers and therapeutic strategies for IHD and related cardiovascular conditions.Highlight : Serum tryptophan and NAD+ levels are lower in IHD patients. SIRT1 levels are significantly higher compared to controls. CRP and troponin confirm inflammation and heart damage. Keywords : Ischemic Heart Disease, Tryptophan, NAD+, SIRT1, CRP, Troponin

Abstract

Background: Endothelial dysfunction is a key factor linking hypertension, inflammation, and metabolic disturbances, yet its biomarker profile in chronic hypertension remains insufficiently clarified. Specific Background: The vascular endothelium regulates vascular tone and homeostasis, but persistent hypertension alters its function through inflammatory and oxidative pathways. Knowledge Gap: Although endothelial impairment is recognized in cardiovascular disease, comprehensive biomarker-based evidence in chronic hypertensive patients is limited, particularly in Middle Eastern populations. Aim: This study aimed to assess endothelial dysfunction biomarkers and their correlations with metabolic and inflammatory markers in patients with chronic hypertension. Results: A case-control study involving 100 hypertensive patients and 50 healthy controls revealed significantly elevated endothelin-1, VCAM-1, ICAM-1, E-selectin, CRP, IL-6, TNF-α, MDA, total cholesterol, LDL-C, triglycerides, and fasting glucose, alongside reduced NO, SOD, and HDL-C (p < 0.001). Biomarker levels correlated positively with age, BMI, hypertension duration, and inflammatory indices. Novelty: This study provides integrative evidence linking vascular, inflammatory, and metabolic biomarkers with disease severity, emphasizing endothelial dysfunction as a multifactorial process in hypertension. Implications: The findings underscore the potential of biomarker profiling to improve risk stratification, early detection of complications, and the design of targeted therapeutic interventions in chronic hypertension.Highlight : Hypertensive patients show higher endothelial dysfunction biomarkers and lower nitric oxide. Inflammation and oxidative stress are strongly associated with hypertension progression. Lipid and glucose abnormalities increase cardiovascular complication risks.
