<span>The Dijkstra algorithm, also termed the shortest-route algorithm, is a model that is categorized within the search algorithms. Its purpose is to discover the shortest-route, from the beginning node (origin node) to any node on the tracks, and is applied to both directional and undirected graphs. However, all edges must have non-negative values. The problem of organizing inter-city flights is one of the most important challenges facing airplanes and how to transport passengers and commercial goods between large cities in less time and at a lower cost. In this paper, the authors implement the Dijkstra algorithm to solve this complex problem and also to update it to see the shortest-route from the origin node (city) to the destination node (other cities) in less time and cost for flights using simulation environment. Such as, when graph nodes describe cities and edge route costs represent driving distances between cities that are linked with the direct road. The experimental results show the ability of the simulation to locate the most cost-effective route in the shortest possible time (seconds), as the test achieved 95% to find the suitable route for flights in the shortest possible time and whatever the number of cities on the tracks application.</span>

It is felt that Modern Banking has become wholly customer – driven and technology driven. During the last decade, technology has been dramatically transforming the banking activities in India. Driven by challenges on competition, rising customer expectation and shrinking margins, banks have been using technology to reduce cost. Apart from competitive environment, there has been deregulation as to rate of interest, technology intensive delivery channel like Internet Banking, Tele Banking, Mobile banking and Automated Teller Machines (ATMs) etc. have created a multiple choice to user of the bank. The banking business is becoming more and more complex with the changes emanating from the liberalization and globalization. For a new bank, customer creation is important, but an established bank it is the retention is much more efficient and cost effective mechanism. Customer Relationship Management (CRM) would also make Indian bankers realize that the purpose of their business is to create and keep a customer and to view the entire business process as consisting of Highly Integrated effort to discover, create and satisfy customer needs. But it is surprising to note that much of the activities of the banking and financial remain focused on customer creation not retention.

Abstract: Today's engendering has a rage about faired bikes because they endeavour ergonomic glances as well as speeds. Although it has now graced a fact that most motorcycle accidents occur in darkness due to poor illumination and are more dangerous when the bike is cornering. As per the present contour of headlamps of fairing bikes, the headlamps become stable, giving rider vision at an upright position. These headlights do not provide enough illumination on bent roads and put riders in a vulnerable position. To overcome this dilemma, an alternative lighting system was needed. The goal of the project is to discover a cost-effective explication, increasing the safety and comfort of the rider. This called for cornering lights for faired bikes to persuade the road at the corner. The cornering lights serve riders by illuminating the shadowed area of the curve providing better vision. The Cornering lights can not only be useful in twilight but also bad weather, the rider can have a clear vision and control on the motorbike. The rider may react to the state of danger at an appropriate time. Keywords: Motorcycle Cornering Lights, Smart Headlights, Guidable headlight, Adaptive headlight, cornering headlight, safety technology, deflecting headlight.

Abstract Background Transmission of SARS-CoV-2 in health care facilities poses a challenge against pandemic control. Health care workers (HCWs) have frequent and high-risk interactions with COVID-19 patients. We undertook a cost-effectiveness analysis to determine optimal testing strategies for screening HCWs to inform strategic decision-making in health care settings. Methods We modeled the number of new infections, quality-adjusted life years lost, and net costs related to six testing strategies including no test. We applied our model to four strata of HCWs, defined by the presence and timing of symptoms. We conducted sensitivity analyses to account for uncertainty in inputs. Results When screening recently symptomatic HCWs, conducting only a PCR test is preferable; it saves costs and improves health outcomes in the first week post-symptom onset, and costs $83,000 per quality-adjusted life year gained in the second week post-symptom onset. When screening HCWs in the late clinical disease stage, none of the testing approaches is cost-effective and thus no testing is preferable, yielding $11 and 0.003 new infections per 10 HCWs. For screening asymptomatic HCWs, antigen testing is preferable to PCR testing due to its lower cost. Conclusions Both PCR and antigen testing are beneficial strategies to identify infected HCWs and reduce transmission of SARS-CoV-2 in health care settings. IgG tests’ value depends on test timing and immunity characteristics, however it is not cost-effective in a low prevalence setting. As the context of the pandemic evolves, our study provides insight to health-care decision makers to keep the health care workforce safe and transmissions low.

Background: Distal radius fractures are the third most common osteoporotic fractures and are frequently treated in emergency department. They have a trimodal peak of occurrence and there has been a significant increase in incidence of involvement in elderly females and young males. Management of these fractures comes with lots of treatment options and challenges to provide good functional outcome. This prospective study was done for the management of communited intra/juxta articular fractures of distal end radius using a bridging external fixator on 25 patients. The principle of ligamentotaxis was used for alignment of fracture fragments and wrist spanning external fixator was used to maintain the fracture reduction.Methods:25 patients of either sex with age group 16 to 80 years were taken from the orthopedic department. After proper primary care, cases were classified using Fernandez classification, and posted for surgery as soon as investigations and fitness were taken.Results:Patients involved in the study were in range of 16 to 78 years with 16 patients having dominant side with road traffic accident as leading cause.Radiological union was seen at an average of 7.3 weeks, 4 patients had superficial pin tract infection, 3 patients had stiffnes and a single case had malunion. Conclusions:Modified clinical scoring system of Green and O’Brien was used to evaluate the overall functional results which showed excellent to good results in 84% of cases. Hence, properly planned and executed bridging external fixator is an easy, cost-effective and reliable treatment modality through the “Principle of Ligamentotaxis”.

Background: Corrosive ingestion can cause severe chemical injury to upper gastrointestinal tract which leads to dysphagia, malnutrition and weight loss. Early nutritional assessment and support through feeding jejunostomy is important and it should be nutritionally optimum and economically balanced. The aim is to compare cost and nutritional status after nutritional support with traditional home kitchen made and commercial formula feed through feeding jejunostomy.Methods:A prospective study included patients on enteral nutrition based on traditional home kitchen feed (cohort-1) and on commercial formula feed (cohort-2). Patient’s body weight, BMI, haemoglobin, serum albumin, nutritional risk index, controlling nutritional status score were checked at the admission, 3rd and 6th month follow up.Results: In cohort 1 mean albumin and haemoglobin raised by 33.13% & 14.60% at 3rd month and 47.23% & 22.3% at 6th month respectively; In cohort 2 it was 9.12% & 2.69% at 3rd month and 17.62% & 6.53% at 6th month respectively. At 6th month in cohort 1 and 2 mean weight gain was 7.56% & 4.0%; mean increase in NRI was 34.78% & 11.5% respectively. Mean CONUT score at six months was better improved in cohort 1 which is 6 to 1 as compared to cohort 2 which was 6 to 3. Mean monthly cost of home-based feeds was significantly lower as compared to commercial feeds (62.14 Rs v/s 682-2354 Rs/day).Conclusions:In corrosive GI tract injury patient enteral nutrition with traditional home kitchen-based feeds is safe, cost effective and associated with better improvement in nutritional status objective parameters.

AbstractThe purpose of this scoping review is to establish the state of the art on economic evaluations in the field of HIV/STI prevention in high-income countries with concentrated epidemic settings and to assess what we know about the cost-effectiveness of different measures. We reviewed economic evaluations of HIV/STI prevention measures published in the Web of Science and Cost-Effectiveness Registry databases. We included a total of 157 studies focusing on structural, behavioural, and biomedical interventions, covering a variety of contexts, target populations and approaches. The majority of studies are based on mathematical modelling and demonstrate that the preventive measures under scrutiny are cost-effective. Interventions targeted at high-risk populations yield the most favourable results. The generalisability and transferability of the study results are limited due to the heterogeneity of the populations, settings and methods involved. Furthermore, the results depend heavily on modelling assumptions. Since evidence is unequally distributed, we discuss implications for future research.
