Published: March 2024

The application of archaeobotany has been increasing for the last ten years in Indonesia, especially for studying the prehistoric human occupation. Indonesia has incredible biodiversity in flora, and the application of archaeobotanical methods and techniques is essential for understanding people-plant relationships in the past. It is also able to support and complement archaeological results and interpretations developed from analyses of other types of material culture. This paper examines archaeobotanical research in Indonesia through available published literature. The result demonstrates archaeobotanical analyses strengthen and enhance the interpretations of archaeological data and highlight the biases in the application towards prehistoric sites. Our research suggests that more recent archaeological sites have great potential for the application of archaeobotany. This approach needs to be introduced in the early stages of all project planning and research so that suitable recovery methods can be utilized, and adequate time and finances for analyses are factored in. The availability of facilities, infrastructure, and human resources to analyze archaeobotanical data will bring more opportunities for analyses in this field.

Published: March 2024

Starting in the 1970s, the captivating archaeological potency in the tropical rainforest area of West Kalimantan started to be revealed. Since then, several expeditions and research had been conducted by The National Research Center for Archaeology and Archaeology Office in South Kalimantan. One of them was an exploration and excavation led by Vida P.R. Kusmartono from 2013-2019. Previous studies have shown that the area of Upper Kapuas Basin possesses numerous archaeological resources, however, many of the areas remain uncovered. This condition is caused by the extensiveness and difficulty of this area to be reached. For that reason, in 2020, we created a predictive model to give an overview of the probability of archaeological caves in this area. This predictive model uses environmental variables and is based on the hypothesis of the environmental resources variables in choosing cave settlements in the prehistory era. The variables used are the elevation of the valley, the proximity distance from the water source, the steepness of the slope, the direction of the slope, and the lineament density. Analysis of the variable elevation of the valley, proximity distance from the water source, and the steepness of the slope produced a map of accessibility. This map was then integrated with the lineament density variable and considered the direction of the slope to produce a map of potential areas for cave settlements.

Introduction: Dyslipidemia is currently the most common risk factor for cardiovascular disease.Population-based studies have confirmed a relationship between dyslipidemia and overweightand obesity, resulting from the pro-inflammatory activity of excessive adipose tissue.

Aim: The aim of study was to compare selected lipid parameters and the prevalence of dyslipidemiain young, healthy normal-weight and overweight subjects.

Material and methods: Study included 60 individuals aged 25-40 years, non-smokers, withnormal fasting blood glucose. The group was divided by BMI value. In all subjects fasting plasmaglucose, TC, TG, HDL-C, apolipoprotein AI and B were measured and the values of LDL-C,non-HDL-C concentrations.

Results: In overweight subjects, higher concentrations of TC, TG, LDL-C, apoB, non-HDL-C andTG:HDL-C were found than in normal weight individuals. In the overweight group, positive correlationswere observed between WHR and TC, waist circumference and non-HDL-C. In normalweight subjects, positive correlations were found between BMI and TC, waist circumferenceand TG. Over 46% of the subjects had hypercholesterolemia, and over 50% had elevated LDL-Clevels. Increased incidence of hypertriglyceridemia, elevated apoB were observed in overweightsubjects, compared to the normal weight.

Conclusions: The prevalence of dyslipidemia is higher in overweight and abdominally obesesubjects, which indicates a higher risk of cardiovascular disease in this group. However, due tothe limitations of the study, primarily the small study group, the results require confirmation ina large population-based study.

Chronic pain affects more than 50 million Americans. Treatments remain inadequate, in large part, because thepathophysiological mechanisms underlying the development of chronic pain remain poorly understood. Painbiomarkers could potentially identify and measure biological pathways and phenotypical expressions that arealtered by pain, provide insight into biological treatment targets, and help identify at-risk patients who might benefit from early intervention. Biomarkers are used to diagnose, track, and treat other diseases, but no validated clinicalbiomarkers exist yet for chronic pain. To address this problem, the National Institutes of Health Common Fundlaunched the Acute to Chronic Pain Signatures (A2CPS) program to evaluate candidate biomarkers, develop theminto biosignatures, and discover novel biomarkers for chronification of pain after surgery. This article discussescandidate biomarkers identified by A2CPS for evaluation, including genomic, proteomic, metabolomic, lipidomic,neuroimaging, psychophysical, psychological, and behavioral measures. Acute to Chronic Pain Signatures will providethe most comprehensive investigation of biomarkers for the transition to chronic postsurgical pain undertaken todate. Data and analytic resources generated by A2CPS will be shared with the scientific community in hopes thatother investigators will extract valuable insights beyond A2CPS’s initial findings. This article will review the identifiedbiomarkers and rationale for including them, the current state of the science on biomarkers of the transition fromacute to chronic pain, gaps in the literature, and how A2CPS will address these gaps.

Published: March 2024

In the face of rapid urbanization, Beijing confronts the escalating challenge of the Urban Heat Island (UHI) effect, characterized by significantly higher temperatures in urban areas compared to their rural surroundings. This phenomenon not only exacerbates the thermal discomfort in city environments but also poses a substantial risk to public health and well-being. Amidst this urban climate crisis, the potential of green spaces emerges as a crucial mitigative and adaptive strategy. This comprehensive study embarks on an in-depth exploration of the multifaceted role that urban greenery plays in combatting the UHI effect and bolstering the well-being of Beijing’s residents. Employing a triangulated research methodology, the study harnesses high-resolution satellite imagery to delineate the thermal footprint of green spaces within the urban matrix of Beijing. Through detailed temperature analysis, it meticulously quantifies the extent to which parks, gardens, and tree-lined avenues contribute to cooling urban environments. Complementing this quantitative analysis, the study engages with the urban populace through extensive surveys, capturing perceptions and lived experiences of the thermal environment and the subjective well-being associated with access to green spaces. The findings reveal a significant cooling effect attributed to urban greenery, with marked temperature reductions in areas with dense vegetation cover. Beyond the thermal benefits, the research uncovers a positive correlation between access to green spaces and improvements in residents’ physical and psychological health, highlighting the critical role of green spaces in promoting urban livability and sustainability. This study advances the discourse on urban planning and public health by providing empirical evidence of the benefits of integrating green spaces into the urban fabric of Beijing. It underscores the urgency of adopting green infrastructure as a standard in urban development projects, not only as a countermeasure to the UHI effect but also as a foundational element for enhancing the quality of life in densely populated urban centers.

Dehydration has long been the preferred method of food preservation over all other techniques. In contrast to other techniques, dehydration uses heat to evaporate extra water from food. This can be simply obtained through solar energy. This work aims to apply appropriate engineering methods to use solar energy for food dehydration efficiently. This work prioritizes both food quality and cost equally. In addition, it features a backup system that operates at night to continuously dehydrate food items with drying times longer than 12 hours, in contrast to previous approaches that are either costly or result in lower-quality products. So, the solar collector is designed at an optimum angle of 27ᵒ with an area of 0.5153 m² to collect useful heat from the sun that develops enough temperature difference to dehydrate some selected food. Experiment results show that the desired purpose is greatly achieved by comparing the dehydrated products with the conventional or commercially available products.
