In this paper, we propose a road surface detection methods by strian gauge sensor applicable to conventional prosthetic systems to improve stability when walking the ramp for the low-powered artificial limbs. Research prosthesis for patients not cut domestic situation is not very lacking cutting patients are using the low power prosthesis using costly imported products sold in developed foreign countries, or with minimal functionality. In the case of low-powered prosthetic gait plains can cause a hazard when walking can be a ramp. The purpose of this paper, by using the ground reaction forces to prevent dangerous situations when walking the ramp for the low-power artificial leg offers a pedestrian road surface condition estimation techniques can identify. Femoral cutting device for making an analysis of the patient"s gait in the walking type and configuration of the lab environment was similar to the sensor for detecting changes in the ground reaction force of the road surface is used in a strain gauge. It confirmed the distinction between the plains and the ramp using the sensors and you want to use as a resource for improving patient safety during the ramp walk of the femoral cutting using the existing power prosthesis system

The accidents that occur on at-grade intersection have a different characteristics in terms of location and type. So, analysis that is adequate for studying accident characteristics by types and locations is needed. In this paper, accidents on at-grade intersections are divided into Straight accident and Turn accidents. In Straight accident analysis, this paper seized the relationships between geometric elements of rural highway and Straight accidents by using total accident data. And in Turn accident analysis, this paper seized the conflict between two moving flows by using collision diagram.

This thesis is to cast a light upon theoretical background of journalistic illustrations, which have recently been playing an important role in visual journalism together with a more conventional tool of photographs. It is also meant to illuminate the status quo and direction of journalistic illustration by analyzing various types of formative characteristics and information-conveying methods that are being employed in newspaper and magazine cartoons on current events.

This study focused on normal force based on the inclination of the surface. To experiment a similar system to a patient with an amputation below the femoral region, we built an artificial leg as a replacement. The center of mass moves as a person walks on a flat ground to inclined one so we used strain gauge to measure normal force of both situation simultaneously. We have used 70kg and 80kg for the test and we discovered 25% potential difference when walking upward and 30.5% when walking downward. With the data, you will be able to see the changes of angle and with that, we provide you the best joint angle for every possible situation. Currently we are about to overcome the defects of artificial leg as well.
