In this paper, an automatic transmission system of traffic information is presented. Here, a traffic event is defined as an obstacle to an emergency vehicle such as an ambulance or a fire truck. When a traffic event is detected from a video recorded by a black box installed in a vehicle, the implemented system automatically transmits a proof image and corresponding information to the control center through an e-mail. For this purpose, we realize an algorithm of identifying the numbers and a character from the license plate, and an algorithm for determining the occurrence of a traffic event. To report the event, a function for automatic transmission of the text and image files through e-mail and file transfer protocol (FTP) is also appended. Therefore, if the traffic event is extended and applied to the presented system, it will be possible to establish a convenient reporting system for the violation of various traffic regulations. In addition, it will contribute to significantly reduce the number of traffic violations against the regulations.

A communications profile is a system that acquires information from communication links to an ambulance or other vehicle moving on a road and compiles a database based on this information. The equipment (six sets of HDTVs, fish-eye camera, satellite antenna with tracking system, and receiving power from the satellite beacon of the N-star) mounted on the roof of the vehicle, image data were obtained at Yokohama Japan. From these data, the polygon of the building was actually produced and has arranged on the map of the Geographical Survey Institute of a 50 m-mesh. The optical study (relationship between visibility rate and elevation angle) were performed on actual data taken by fish-eye lens, and simulated data by 3D-Map with polygons. There was no big difference. This 3D map system then predicts the communication links that will be available at a given location. For line-of-sight communication, optical analysis allows approximation if the frequency is sufficiently high. For non-line-of-sight communication, previously obtained electric power data can be used as reference information for approximation in certain cases when combined with predicted values calculated based on a 3D map. 3D maps are more effective than 2D maps for landing emergency medical helicopters on public roadways in the event of a disaster. Using advanced imaging technologies, we have produced a semi-automatic creation of a high-precision 3D map at Yokohama Yamashita Park and vicinity and assessed its effectiveness on telecommunications and ambulatory merits.

Purpose: This study aimed to obtain, categorize, and analyze baseline data regarding the subjective perception of ambulances from the consumers' perspective, which can be utilized for improving emergency medical service systems. Methods: Fifty people aged 20 to 40 years old were selected as P samples. Data from 35 statements of Q-cards and Q-sample distribution plots were gathered using Q-sort and analyzed using the PC-QUANL program for major factor analysis. Results: We found four unique characteristics which accounted for 57.57% of the total variation: "Considerate of emergency situations," "Identifying emergency patients," "Trusting emergency vehicles," and "Sympathizing with emergency patients." Conclusion: Organizations that provide emergency medical services using ambulances should plan and render patient care according to the four types of public perception of ambulances.

As services for citizens' security and protection offered at the national and social levels become more widely recognized across society, the more frequent use of ambulances by patients with both minor and major injuries is being observed. However, the number of safety accidents during transport by ambulances, which are responsible for the prompt transport of patients, has been rising in tandem with the increase in their use. This is due not only to their inconspicuousness both on the road and in other environments where these vehicles are exposed, but also to the high chance of secondary accidents, putting the lives of both patients and emergency responders at risk. It is important to study and develop designs that guarantee protection against safety accidents, noting that ambulances are completely exposed and unprotected on the road on cloudy days and at night-time. In addition, by identifying colors and design motives that enhance the conspicuity of ambulances from a distance and increase their security, emergency responders and patients can be safely protected, the identity of the ambulances can be reinforced and modernized, and the sense oppression which can be visually imposed on patients in a psychologically unstable condition can be eased. Against this backdrop, this study presents the process involved in deriving the exteriors of ambulances in Korea, including their colors and patterns, by examining the established global best practices and identifying the need for more studies into colors, even unconventional ones, that improve their safety.

This research was conducted to improve the image of female emergency workers in a fire service organization by studying the perception trends of the increasing number of female paramedics. This human resource can be utilized more effectively by using the study results as baseline data. We conducted a survey from May 1 to June 30, 2013. The survey was analyzed using Q methodology and the program QUANL. For the Q sample, 31 emergency rescue paramedic students who had experienced ambulance field education were selected. As a result, four types of female paramedics were found; "superwoman," "hero" (who pushes against limits of stamina), "delicate guardian angel," and "skillful desk worker." The explanation powers were as follows: type I: 42.2%; type II: 4.8%; type III: 4%; and type IV: 3.6%. The sum of the figures explained 54.7% of the total variables. Generally, the students recognized female paramedics as professionals, but physical strength, baby care, and caring were considered as burdens. This requires changes in the organization's perception of female paramedics and an institutional strategy.
