Published: September 2023

Mangrove ecosystems have become a critical habitat for sustaining renewable energy production, and their management is essential to maintain their ecological, economic, and social functions. This study aimed to analyze the multidimensional aspects of mangrove ecosystem management for sustainable renewable energy production in the Tebing Tinggi, Kepulauan Meranti, Riau. This study formulates sustainable management schemes for the mangrove ecosystem in the Tebing Tinggi, Kepulauan Meranti, Riau by analyzing the ecological, economic, social, legal-institutional, and technological aspects of the ecosystem. To conduct this analysis, researchers used the Multidimensional Scaling (MDS) approach, which relies on an algorithm called the MDS algorithm. The findings from the study reveal that the use of mangroves can increase people's income, but the level of community education is still low, and there is a lack of community participation in mangrove ecosystem management activities. Based on the Rap-Mangrove analysis, the multidimensional index of mangrove ecosystem management is considered sufficiently sustainable. The findings emphasized the significance of community participation and education in managing mangrove ecosystems. The study concludes that sustainable management schemes for mangrove ecosystems are necessary to ensure their continued contribution to renewable energy production.

Published: September 2023

Introduction. A Nasogastric Tube (NGT) is a flexible tube inserted into the stomach through the nose (nares) to preserve nutritional support. The use of NGT is claimed to increase the risk of pathogenic bacteria colonization due to stagnation, ultimately worsening the patient's outcome. Proper identification of bacterial patterns is required as colonization grows to avoid further complications. This study aims to compare oropharyngeal microorganism patterns in patients with NGT to those without NGT at Dr. Mohammad Hoesin Palembang.
Methods. A cross-sectional observational study was used. From September 2022 to October 2022, data were collected using primary data from interviews (research questionnaires) and oropharyngeal swab results (bacterial culture) in 42 patients undergoing treatment at Dr. RSUP. Mohammad Hoesin Palembang's ENT department.
Results. Positive colonization was found in all patients with NGT (100%) and 90.47% in the group without NGT. P. aeruginosa was the most common pathogen in the NGT group (47.62%). The use of NGT, body weight, height, and body mass index were significant risk factors in the incidence of P. aeruginosa colonization (p=0,012).
Conclusion. There is a significant difference in P. aeruginosa colonization between NGT and non-NGT users. NGT use is the most important driving factors of colonization development. However, these findings were not found in colonization in general or specific bacteria categories.

This study aims to test the reliability and construct validity of the Holland RIASEC instrument, which is a psychometric approach to examining human personality based on six domains, namely Realistic, Investigative, Artistic, Social, Enterprising, and Conventional. This instrument is used to measure and recommend the type of work that suits students’ personalities in the vocational field. This study uses a non-experimental method with a quantitative research approach and involved 178 vocational students at Universitas Negeri Padang. The data analysis techniques used are Structural Equation Modeling (SEM) and Confirmatory Factor Analysis (CFA). The results showed that the reliability of the six Indonesian version of Holland’s personality was quite high, with Cronbach’s alpha values between 0.601 and 0.699. In addition, there was a positive correlation between Holland’s personality. Construct validity showed a fit model with a p-value of 0.26972 and RMSEA = 0.02. This indicates that the empirical data is in line with the RIASEC typology model, which is the theoretical concept.
In vivo tracing of the ascending vagal projections to the brain with manganese enhanced magnetic resonance imaging
Authors: Oleson Steven , Cao Jiayue , Wang Xiaokai , Liu Zhongming 
Published: September 2023

IntroductionThe vagus nerve, the primary neural pathway mediating brain-body interactions, plays an essential role in transmitting bodily signals to the brain. Despite its significance, our understanding of the detailed organization and functionality of vagal afferent projections remains incomplete.MethodsIn this study, we utilized manganese-enhanced magnetic resonance imaging (MEMRI) as a non-invasive and in vivo method for tracing vagal nerve projections to the brainstem and assessing their functional dependence on cervical vagus nerve stimulation (VNS). Manganese chloride solution was injected into the nodose ganglion of rats, and T1-weighted MRI scans were performed at both 12 and 24 h after the injection.ResultsOur findings reveal that vagal afferent neurons can uptake and transport manganese ions, serving as a surrogate for calcium ions, to the nucleus tractus solitarius (NTS) in the brainstem. In the absence of VNS, we observed significant contrast enhancements of around 19–24% in the NTS ipsilateral to the injection side. Application of VNS for 4 h further promoted nerve activity, leading to greater contrast enhancements of 40–43% in the NTS.DiscussionThese results demonstrate the potential of MEMRI for high-resolution, activity-dependent tracing of vagal afferents, providing a valuable tool for the structural and functional assessment of the vagus nerve and its influence on brain activity.
