This research paper aimed to develop a constructive model that would explain the structure of relationships between emotional intelligence, self-efficacy, and psychological well-being in the light of perceived achievement and self-actualization. The research sample consisted of (346) students from the first and fourth years of the Faculty of Education - Damanhour University. They were between 18-22 years old. The emotional intelligence scale (Mayer, Salovey, & Caruso, 2002), General Self-Efficacy Scale (Schwarzer & Jerusalem, 1995) Psychological Well-Being Scale (Springer & Hauser, 2006), Perceived Achievement Scale and Self-Actualization Scale were all applied to the sample. The data was analyzed using path analysis found in the Liseral program (Liseral 8.8). The study results led to a causal constructive model that explains the relationship between emotional intelligence, self-efficacy and psychological well-being in the light of perceived achievement and self-actualization. The results also showed a statistically significant impact of self-efficacy on perceived achievement and psychological wellbeing. There was also a statistically significant impact of self-efficacy and perceived achievement on self-actualization and psychological wellbeing. It was also clear that emotional intelligence and self-efficacy had a statistically significant impact on self-actualization and psychological wellbeing. Self-efficacy had the highest impact, whereas perceived achievement and self-actualization had lesser impact; and emotional intelligence had the least impact.
Keywords: emotional Intelligence, self-efficacy, psychological wellbeing, perceived achievement, self-actualization.

Authors: Wróblewska Agnieszka , Bhatia Mohit , Matthews‑Brzozowska Teresa , Polańska Adriana 
Published: February 2021

Symmetry, among others, is the exponent of the correct face structure. 31 publications from the last 5 years were selected from medical databases, which discussed factors that may affect facial symmetry. According to the analyzed reports, the etiology of facial asymmetry is multifactorial through functional, neuromuscular, stomatognathic, environmental, congenital, acquired as a result of injuries, cancer, chronic skin diseases and aging process. Fluctuation asymmetry within the population average does not significantly affect the assessment of facial attractiveness, while a significant degree of fluctuation asymmetry can have a destructive impact on the multi‑faceted quality of life of an individual.

Semak Daun Island was part of the Kepulauan Seribu which was a marine tourism destination such as snorkeling and diving site. The existence of these activities had been affecting the condition of the biota community that lives in these waters including macroalgae. The condition of macroalgae communities can be observed by abundance, diversity, uniformity and dominance analysis that occur in these communities that are known as the community structure. The purpose of this study was to determine the structure of macroalgae communities (abundance, diversity, uniformity and dominance) in Semak Daun Island. This research results was found 3 divisions, 10 orders, 13 families, 15 genera and 20 species of macroalgae. The abundance of macroalgae ranges from 235 - 782 individuals/100m2, classified as low abundance. Diversity ranges from 0.96 to 1.83, classified as low diversity. Uniformity ranges from 0.4 to 0.71, including the moderate uniformity and Dominance ranges from 0.22 to 0.57 belong to the low to moderate category, with the most dominant species being Galaxaura rugosa. Physics-chemical parameters of water in general are included in the normal range to support macroalgae life. Based on this, the condition of the macroalgae community structure on Semak Daun Island which is in a less favorable condition is likely due to the existence of snorkeling and diving activities by tourists.

The Sunda Strait Tsunami (end of 2018) has an impact on the seagrass ecosystem in Tanjung Lesung. This paper described the seagrass ecosystem’s changes after the tsunami disaster. Sentinel-2 satellite image processing in 2018 and 2019 was used to see changes in the seagrass area. The field data were collected from May–July 2019, including the types of seagrass ecosystems based on data seagrass existence, density and biomass. Then, the seagrass sample was analyzed biomass after the tsunami disaster. The results showed that the data from 2018 – 2019 showed decreased seagrass area from 105.86 to 77.07 ha. Seagrass density dropped quite dramatically, and the species of Halodule uninervis was no longer found. The ratio of after tsunami BG/AbG dry biomass has doubled compared to before the tsunami, which indicates the seagrass's lower biomass is higher than the upper part allegedly due to tsunami impacts. Based on the results obtained, it can be concluded that the seagrass ecosystems changed and disrupted by the tsunami. Keywords: Seagrass, Tanjung Lesung, Tsunami, Sentinel-2

Decade-long shift in the rate of global mean sea-level rise
Authors: Cha Hyeonsoo , Moon Jae-Hong , Kim Taekyun , Song Yuhe Tony 
Published: February 2021

Abstract
Recent advances in satellite measurements and ocean heat-content estimates have enabled the monitoring of global mean sea level (GMSL) budget components and understanding of ocean effects on the Earth’s energy imbalance and hydrology. We observed a notable accelerating GMSL rise rate in the recent decade after the warming “hiatus” during the 2000s, and demonstrated that this was attributed to decade-long shifts in ocean heat storage and hydrology. Since ~2011, climate-driven changes have resulted in additional ocean mass gain (271±89 Gt yr-1) from glacier-free land water storage and increased ocean heat uptake (0.28±0.17 W m-2), accelerating the GMSL rise rate by 1.4±0.4 mm yr-1. The suggested estimates of sea-level and Earth’s energy budgets highlight the importance of natural variability in understanding the impacts of the ongoing sea-level rise.

Published: February 2021

Abstract
Introduction: Digoxin is used in patients with chronic heart failure (CHF) who remain symptomatic despite optimal medical treatment. Impaired renal function is commonly associated with CHF. We investigated the relation between digoxin use and change in renal function over time in patients with CHF. Methods: 1241 patients with symptoms and signs of CHF (average age 72 years (64% male), and median NTproBNP 1426 ng/l (interquartile range 632 - 2897) were divided into four groups: never on digoxin (N=394); digoxin throughout (N= 449); started digoxin at some point after baseline (N=367); and stopped digoxin at some point after baseline (N= 31). The rate of change of estimated glomerular filtration rate (eGFR) was calculated using linear regression. Results: Patients on digoxin throughout had a significantly greater rate of decline in eGFR per year than patients not on digoxin throughout (mean (± standard deviation); -5 (13) ml/min/1.73m2 per year v -2 (10) ml/min/1.73m2 per year, P= 0.02). In those patients who started digoxin during follow up, there was no significant difference in the rate of decline in eGFR before and after starting digoxin. There was no correlation between baseline eGFR (or rate of decline in eGFR) and age, haemoglobin or NTproBNP. Compared to patients taking both angiotensin-converting-enzyme inhibitor (ACEi) or angiotensin receptor blockers (ARB) and beta-blocker (BB), patients who were not taking an ACEi/ARB or BB had a numerically faster rate of decline in eGFR, although this was not statistically significant.Conclusion: The rate of decline in renal function is greater in patients with CHF who are taking digoxin.

Abstract
BackgroundRhizosphere microbes possess important effects on plant growth and quality. Here we collected tobacco roots and leaf samples from ten places in Yunnan province to investigate the interaction of the rhizosphere microbes, the soil physicochemical characteristics, and the tobacco leaf properties. ResultsA high-throughput sequencing method was used to sequence the V3–V4 region of 16S rRNA genes, and the operational taxonomic units (OTUs) were clustered using QIIME under 97% identity. A total of 4571 OTUs were obtained from the 30 tobacco root samples, and the top three phyla were Proteobacteria, Acidobacteria, and Actinobacteria, while the top three annotated genera were Gp6, Gemmatimonas, and Gp4. Redundancy analysis (RDA) showed that most of the soil physicochemical properties (10 out of 17) had a significant influence on the rhizosphere microbial community. Both correlation analysis and RDA analysis revealed that quick potassium (K) and Acidobacteria_Gp3 had a significant correlation with the tobacco leaf properties. The variance partitioning analysis showed that rhizosphere microbes had a bigger influence on the tobacco leaf properties. ConclusionsOur results showed great differences in the rhizosphere microbial diversity of tobacco and complex interaction among the microbial diversity, soil physicochemical characteristics, and tobacco leaf properties.
