In recent days, leadership quality considered as significant area. Various definitions and dimensions are theorized by different researches, generating the leadership shows the clear indication about the organization behaviour, society and people management in various countries. The organisations behaviours and various procedures modified for the employees reduction in the organization. Apart from all modifications the most significant aspect which is directly linked to the employee turnover reduction is the leadership quality and effectiveness. This study is performing a vigorous statistical analysis for figuring the relationship between employee and firm. Various issues have been addressed by the leadership and also job satisfaction, commitment and other factors exhibited from the different existing studies. To overcome these issues an empirical and quantitative analysis is carried out. A secondary data based approach with a sample size of 215 is done. The samples were gathered from the existing data which were published in various articles and journals earlier. The leadership quality is the prediction and the turnover intention is the outcome. Thus in human resource management practices, management of the employee turnover is essential with respect to the prediction and control of employee turnover. Existing studies analysis are concentrated and shows that the direct antecedents are turnover intention and employee turnover is thus predicted. The outcome proves that a strong leader with effe3ctive leadership qualities and prominent organisational culture and behaviour will lead to decrease the employee reduction.
The COVID-19 pandemic affected the entire world and created global public health problem. It is airborne and spreads rapidly. Many countries started COVID-19 disease surveillance and scaled up their hospital facilities. However, the number of COVID-19 infection cases is increasing due to new variants and lack of vaccines in poor countries. The healthcare workers (HCWs) are in the frontline to contain the spread of this disease. The hospital environment poses health hazard to the HCWs if proper safety precautions and procedure are not followed. The increase in COVID-19 cases among HCWs may reduce the strength of workforce which fights against the pandemic. Also, the lack of PPEs and unscientific disposal of hospital wastes related to COVID-19 may amplify the epidemic. The engineering intervention should be adopted to mitigate the spread of COVID-19 in hospital environment. This article reviews the source of COVID-19 in hospital environment and steps to be taken to mitigate COVID-19 spread.
This paper takes the supply situation of the tourism industry precision driven by big data as the research object. Based on the perspective of system service supply and demand, the basic framework of the tourism industry\'s precision service is constructed by data information method, qualitative and quantitative analysis method, etc. By reviewing the literature, the dominant indexes to the tourism industry refinement management were selected. The final tourism industry evaluation index system was constructed using principal component analysis. Each index\'s weights in the criterion and factor layers were calculated using Analytic Hierarchy Process ( AHP). Finally, the relevant cases are analyzed by using the fuzzy comprehensive evaluation method.
Soil provides all the basic needs to us and is the most essential medium for growing plants. Thirteen soil samples from 0 –15 cm depth were collected in the agricultural land near industry, Visakhapatnam, Andhra Pradesh (India). The physico – chemical parameters such as pH, EC, Organic matter, organic carbon, nitrogen, potassium and phosphorous of soil were analysed. The result reveals that soil exhibited alkaline characteristics, on an average in organic carbon and organic matter. An understanding of physical and chemical condition of any soil is essential for proper implementation of the other management practices. Therefore the physico-chemical study of soil is very important because both physical and chemical properties which affect the soil productivity. This knowledge will create awareness among the farmers about economic productivity.

The objectives of this research were to determine the variation in the amount and composition of the essential oil from the herbaceous plant and the essential oil from H. heterophyllum capsule-type fruits according to different harvesting periods. The samples of herbaceous plant in four different growth stages as before flowering, beginning flowering, 50% of flowering, and full flowering and capsule-type fruits in full maturity stage were taken from plants in natural environment. The highest essential oil rate (0.09%) in aerial parts was recorded in before flowering stage. Also, germacrene-D, δ-cadinene, spathulenol, and α-guaiene in the plant and germacrene-D, caryophyllene oxide, and α-guaiene in dry capsule-type fruits were determined as main components. The essential oil content and the components show variation depending on the developmental stages of the plant and the part used
Vernadsky's statement about the impact of the processes in the earth's crust on the processes and events in the biosphere was analyzed. The reason for the repeatability of biosphere events throughout the geological history of the Earth was considered. in the framework of the recently proposed (Ivlev 2015, 2019) model of the global carbon cycle. It was established that the reason for the repeatability of the processes and events in the biosphere is the orogenic cycles, caused by the uneven movement of lithosphere plates. Thanks to this movement, the evolution of global photosynthesis on the Earth occurs in a pulsation mode. Each pulse corresponds to a separate orogenic cycle. The corresponding processes and events in the biosphere are repeated in the subsequent orogenic cycles. The repetition takes place at the background of a continuous decrease of the CO2 content in the environment and an continues increase of oxygen concentration. These changes determine the unidirectional and irreversible nature of the evolution and ultimately bring carbon cycle to an ecological compensation point. The validity of the conclusions is based on the logic and facts as well as on the knowledge of the physical and chemical laws taking into account the actualism principle. The validity of the model itself is proved by the same sequence of biosphere events, which was established independently by different researchers. It is shown that the irreversible nature of the evolution of oxygenic photosynthesis ultimately leads the global carbon cycle to the ecological compensation point, where orogenic cycles are transformed into relatively short-term climatic oscillations.
Background: Blood borne diseases are important diseases that can transmit their etiological agents in the medical office. One of the most feared due to its contagious remains hepatitis B virus (HBV). This infection is vaccine preventable. The present study aimed to assess the HBV infection and HBV vaccination status of Romanian dental professionals exposed to Toxoplasma gondii, a very common parasitic worldwide infection. We assessed HBV vaccination status, attitudes, knowledge, and fears. Methods: In 2024, an analytical cross-sectional observational survey was carried out in six months, from February to August, in dental offices in Romania. Using SPSS (version 23), data collected through a self administered questionnaire were examined. Where applicable, chi-square tests were employed. Results: Responses from 1708 individuals were examined. The median age of the cohort under study was 31.22 ± 12.7 years (range: 18–76 years). 742 (43.44%) of the participants had worked in dental offices for more than three years, and 1470 (86.07%) were from urban dental offices. 322 (18.85%) nurses, 308 (18.03%) dental technicians, and 392 (22.95%) dentists were present. 1120 dentists (65.57%) had received an HBV vaccination. 420 (24.59%) had received an HBV vaccination before to beginning work at the dental clinic. The dental technician category had the highest rate of HBV not-vaccination, at 154 (13.75%). The urban dental office had a significant (p<0.05) correlation with HBV vaccination status (OR = 0.38; 95% CI: 0.28-0.51). More than half of the respondents, 1456 (85.25%), had not been exposed to HBV while working in a dental office, and 882 (51.64%) were unaware of post-exposure HBV prophylaxis. 98 dentists (5.74%) were unaware of the HBV transmission mechanism. Of the dental professionals who worked with or for patients infected with HBV, 812 (47.54%) expressed fear of contracting the virus. Testing for antiHBs antibodies (OR = 0.38; 95% CI:0.29–0.51), knowledge of pre-exposure to HBV prophylaxis (OR = 0.49; 95% CI:0.37-0.67), and the respondents' role/occupation in the dental office (OR = 0.70; 95% CI:0.56–0.88) were all significantly correlated with the fear of contracting HBV (p<0.05, nonparametric Chi-square test). Conclusions: The current study found disparities in knowledge, attitudes, and opinions within the group under investigation, as well as a low level of HBV immunization in the dentist’s office. The dental technicians were terrified of the possibility of contracting HBV and had received fewer HBV vaccinations. They were unaware of the possibility of contracting HBV. Dental professionals in Romania should be encouraged to learn about HBV prevention before and after exposure. The level or titer of protective antiHBs antibodies should be measured to lessen the concern of contracting HBV while working with or for patients who have the virus. Romanian dental offices need to enhance their HBV vaccination status.
