Physical fitness and health are reciprocal to each other and examining adiposity is an important parameter to assess physical fitness. The present study examines the relationship between different adiposity markers and physical fitness based on occupation. A cross sectional sample of 82 security guards (mean age: 36.86 ± 8.72) and 43 students (mean age: 23.4 ± 3.86) of Delhi University were studied. Anthropometric measurements (height, body weight, waist and hip circumference) and socio-demographic characteristics were ascertained. Body composition parameters (body fat percentage, fat mass, fat free mass, muscle mass, total body water, bone mass and visceral fat) were assessed by bioelectric-impedance method using Tanita Body Composition Analyzer (BCA). Harvard step test was performed to test the physical fitness using Rapid Fitness Index. Student’s t test was used to compare the physical fitness and adiposity markers between the security guards and the students. ANOVA was used to categorize the level of physical fitness with adiposity markers amongst the two groups. As RFI scores decreased, mean value of body weight, waist circumference, hip circumference, MUAC, fat mass, visceral fat and BMI increased among the security guards showing a trend which indicates that with an increase in adiposity, the tendency to perform physical work decreases. However, no consistent trend as such was observed amongst the students between the RFI categories. Nevertheless, Delhi University students were found to be more physically fit than the security guards that may be attributable to the differences in their leisure time physical activity preferences and occupational workloads besides the underlying genetic, metabolic or dietary influences. Workplace interventions to reduce occupational sitting among the university security guards may boost cardiorespiratory fitness in the long run. 展开更多

Background and aim: Occupational stress occurs when there is a disequilibrium between job demands and capabilities. Being employed as a security guard exposes the subject to potentially dangerous situations. Security guards are engaged in a profession that confronts violators of the law as well as violence and thus are more likely to be exposed to traumatic experiences. So it is very important to assess the level of stress they possess and make them aware of the harmful effects and how to manage it. Hence, there is a need to assess the level of occupational stress and to evaluate the effectiveness of PTP on knowledge regarding occupational stress and its management among security guards of a selected organization, Shimoga, Karnataka. Results: Demonstrated that the majority of the security guards were having a moderate level of occupational stress. Among 80 security guards, 59 (74%) were having a moderate level of occupational stress, 21 (26%) were having a severe level of occupational stress and none of them possessed a mild level of occupational stress. Conclusion: This study contributes to the emerging body of knowledge about occupational stress in their security profession and it is important to plan the healthy coping strategies to cope up with their occupational stress. 展开更多

The results of scientific studies of human social facts in the field of health show that the management of a patient should involve the patient’s entourage,whatever the status or size of the health establishment.In healthcare establishments in the Congo,the following are recognised as being responsible for medical care:specialist doctors,doctors,midwives,nurses and care assistants.The patient’s family and close friends are responsible for looking after the patient and financing care.The hospital infrastructure does not provide any space for the patient warden who accompany the patient during reception and hospitalisation.This makes Congolese hospitals inefficient for patient care.How can we integrate the function of the Sick guard and the assistance of the family,in order to reduce the mortality rate and repair the harm caused to patients requiring the presence of relatives during their stay in hospital,which is considered to be a dangerous place?This article examines the functional principles for configuring the space that patient warden would occupy in the patient care system.On the basis of a documentary analysis of sociological and architectural studies of existing facilities,this article proposes a typical accommodation model with the spaces needed to ensure the well-being and effectiveness of the patient warden with the patient.These are rooms with minimum space for 2 to 4 individual beds,equipped with toilets and showers.The accommodation has a dining area,kitchen and laundry facilities.In the future,this accommodation will become part of the hospital estate and may be occupied by orderlies and patient warden recruited by the hospital administration. 展开更多

Grape crops are a great source of income for farmers.The yield and quality of grapes can be improved by preventing and treating diseases.The farmer’s yield will be dramatically impacted if diseases are found on grape leaves.Automatic detection can reduce the chances of leaf diseases affecting other healthy plants.Several studies have been conducted to detect grape leaf diseases,but most fail to engage with end users and integrate the model with real-time mobile applications.This study developed a mobile-based grape leaf disease detection(GLDD)application to identify infected leaves,Grape Guard,based on a TensorFlow Lite(TFLite)model generated from the You Only Look Once(YOLO)v8 model.A public grape leaf disease dataset containing four classes was used to train the model.The results of this study were relied on the YOLO architecture,specifically YOLOv5 and YOLOv8.After extensive experiments with different image sizes,YOLOv8 performed better than YOLOv5.YOLOv8 achieved 99.9%precision,100%recall,99.5%mean average precision(mAP),and 88%mAP50-95 for all classes to detect grape leaf diseases.The Grape Guard android mobile application can accurately detect the grape leaf disease by capturing images from grape vines. 展开更多
