“…We identified 42 Louisiana RTFs treating BC patients from the LTR database. The distances from patients' residential addresses to the nearest government‐owned RTFs, and private RTFs in Louisiana were calculated using the Haversine formula, 34 which calculates the shortest great‐circle distance between two points on a sphere from their longitudes and latitudes.…”

Background Breast‐conserving surgery plus radiation (BCT) yields equivalent or better survival than mastectomy for early‐stage breast cancer (ESBC) women. However, nationwide mastectomy trends increased in recent decades, attracting studies on underlying causes. Prior research identified that long distance to the radiation treatment facility (RTF) was associated with mastectomy. Still, it is unclear whether such association applies to young and old ESBC women comparably. We sought to delineate such impacts by age. Methods Women diagnosed with stages 0–II breast cancer in 2013–2017 receiving either BCT or mastectomy were identified from the Louisiana Tumor Registry. We assessed the association of surgery (mastectomy vs. BCT) with the distance to the nearest or nearest accessible RTFs using multivariable logistic regression adjusting the socio‐demographic and tumor characteristics. The nearest accessible RTF was determined based on patients' health insurance. For Medicaid, uninsured, and unknown insurance patients, the nearest accessible RTF is the nearest RTF owned by the government. The interaction effect of age and distance was evaluated as well. Results Of 11,604 patients, 46.7% received mastectomy. Compared with distance ≤5 miles to the nearest RTF, those with distance ≥40 miles or 15–40 miles had higher odds of mastectomy (adjusted (adj) OR = 1.39, 95% CI = 1.07–1.82; adj OR = 1.17, 95% CI = 1.02–1.34). To the nearest accessible RTF, the adj ORs were 1.25 (95% CI = 1.03–1.51) and 1.19 (95% CI = 1.04–1.35), respectively. Age‐stratified analysis showed the significant association ( p < 0.05) only presented among women aged ≥65, but not those aged <65 years. Conclusion Distance to the nearest or nearest accessible RTF influences the surgery choice, especially among women in Louisiana ≥65 years with ESBC. Further understanding of factors leading to the decision for mastectomy in this age group is needed.

“…The development of the application is carried out by using the PHP programming language and the Haversine method to determine the closest distance of a restaurant. The results of the obtained data were tested by using a black box to show that a test by using this application is similar to the manual method [10]. Aulia Aulia, Zakir, Dafitri, Siregar, & Hasdiana conducted research that related to the situation in the restaurant.…”

Purus village in Padang City which has an area of 0.86 km2 consisting of 8 RW and 28 RT has a population of 8,075 people with a density of 11,875. As a result, people are always haunted by fear and always feel threatened if an earthquake occurs. If an earthquake and tsunami occur, what the community needs at that time is information about a safe zone that can be reached to save themselves and their families. For this reason, there needs to be an educational process for the community so that they have a culture of disaster awareness in the form of a system that is able to inform the community where the closest safe zone they can reach is the route they must take when a disaster strikes so that it can provide a sense of security because of safety guarantees. This study aims to determine the shortest route that can be taken by the user (community) during a disaster to reduce the risk of a greater number of victims by using the Breadth first search algorithm which is integrated into a web-based GIS application. By determining the starting point which is the user's position when the disaster occurs, and then determining the end point which is the location of the closest shelter, it will be possible to calculate the shortest distance that can be reached by the user at that time. The method chosen in this study is a waterfall because each step of the research carried out must be sequential and structured to avoid the risk of errors in each sequence of processes carried out. The results of this study can be proven by doing manual calculations to determine the shortest distance which will later be compared with the results of applications that have been designed using the BFS algorithm.

Beauty salons and barber shop are a necessity for almost everyone. Nowadays, the business processes of them mostly still use conventional methods. The method gives obstacles to customers who have a lot of activities, for example, they have to come directly to the beauty salon or barber shop to take the queue. In addition, it is hard to promote, communicate and assess without E-CRM media. The location is also difficult to find because there is no guide mark on Google Maps. The Geographic Information System for Booking Beauty Salon and Barber Shop provides solutions for making scheduled bookings and transactions by using the e-CRM approach as in the application of promotional features to attract customers. There are some features offered in the application, such as chat features for communication, rating and review features to assess the services obtained, and route feature as a solution to show the location of selected vendors. The implementation process requires an Android smartphone and a computer device with software including Android Studio, SQLYog, XAMPP, and Visual Studio Code. The results of the implementation of the system based on the questionnaire showed 25.8% answered 'excellent', 45.7% answered 'good', 28.3% answered 'enough', and 0.2% answered 'bad'.
