ADAS(Advanced Driver Assistance System) for automobiles is being developed based on evaluation protocols. Radars, LiDars, and cameras are also being developed by many auto parts suppliers including automobile manufacturer, for automobile safety, but protocols following weather condition are still weak. In South Korea, typhoons that occur in summer in four seasons are the most damaging to property. Therefore, the research is needed based on the virtual environmental conditions of typhoons such as precipitation, wind speed, and temperature. In this study, it was derived that the average error rate for each typhoons condition such as SNR (Signal to Noise Ratio) and RCS (Radar Cross Section) is different by analyzing the effect of typhoons occurring in South Korea on radar according to virtual environmental conditions. It is expected that radar’s analysis from typhoon conditions data can be used to develop radar sensors.

In this study, the Euro NCAP-based AEB system evaluation simulation was conducted by applying the calculated corrected TTC by road condition estimation of scenarios (CPFA, CPNC, CPLA) of the V2P situation scenario using PC-Crash, a program used for traffic accident analysis. The scenario was evaluated in consideration of the two road conditions. the low-speed conditions among every scenarios avoided collision, but in the medium and high-speed conditions has been collided with pedestrian. It was confirmed that the time point at recognizing pedestrian was lower than set TTC at which AEB system was operated, even though the AEB was operated immediately, a collision occurred due to insufficient braking distance. As in this study, if studies such as V2V, V2P, and V2B considering road friction are actively conducted, it is expected to be useful data for automobile accident prevention and accident analysis.

The event recording devices such as EDR and DTG have recently been developed and installed in automobiles. The reliability of EDR application is being conducted in many previous studies, but with the development and development of autonomous vehicles, it is necessary to study the reliability of EDR and DTG application results for programs that can analyze autonomous driving. Therefore, in this study, the analysis was carried out in a way to secure the reliability of the application results of EDR and DTG of Carmaker, which can analyze the traffic accident analysis program PC-Crash and autonomous driving, and secure the reliability of the Carmaker program that applied EDR in Korea and abroad. As a result of the analysis, it was found that the speed error rate gradually increased from high speed to low speed, and the maximum error speed was less than 5 km/h through the average error rate for each speed. In the future, it is thought that it can be usefully used for analysis of traffic accidents in the event of autonomous vehicle accidents.

Recently the incidence of rollover accidents has increased due to the increase of SUV, and the probability of occupant injury in rollover accidents is very high, so research is needed accordingly. In this study, PC-CRASH, which is a program used for traffic accident analysis, is used for checking rollover speed and rollover angle of each situation in case of rollover accident, and applied to design variables of LS-DYNA which is finite element analysis program, so deformation displacements of roof according to collision velocity and angle were derived. Also, it is possible to predict rollover vehicle speed by using the derived value and the measured deformation displacement of roof in actual rollover accident, and it is possible to reconstruct accident more accurately by applying to PC-Crash which is traffic accident reconstruction program, so it is thought that it can be utilized analyzing traffic accident usefully.

The Korean daily intake of vegetable oils has increased about 2.5-fold from 17 g/day to 46 g/day for the last several decades. Perilla (Perilla frutescens var. frutescens) has been cultivated in Korea for a long time as a dietary oil seed which has the highest content of α-linolenic acid, accounting for nearly 60%. It is known that the main role of ALA is as a precursor to the longer-chain ω-3, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), the metabolic products of α-linolenic acid (ALA, ω-3). Dietary ω-3 fatty acids reduce inflammation and the risk of chronic diseases such as heart disease, cancer, and arthritis, but they also may act as functional components for cognitive and behavioral function. Thus, α -linolenic acid is one of the essential nutrients in modern dietary patterns in which much linoleic acid is consumed. Nevertheless, perilla oil, rich in α-linolenic acid, can be easily oxidized, giving rise to controversies with respect to shelf life, the deterioration of the product’s commercial value, and further related toxicity. Recent research using genetic modifications has tried to develop new plant oil seeds that balance the ratio of ω-6/ω-3 fatty acids. Such trials could be a strategy for improving an easily oxidizable property of perilla oil due to high α-linolenic acid. Alternatively, appropriate application of antioxidant to the oil can be considerable.

The main objective of the study was to investigate the phytic acid contents of various cereals and legumes produced in Korea. The results showed that the phytic acid contents of buckwheat, foxtail millets, sorghum, millet, barley, jobs' tears, yellow corn and wheat flour (Urimil) were in a range of 0.13 to 2.27%. The contents of the phytic acid ranged from 1.03 to 1.16% for legumes including red Indian bean, black Indian bean, mung bean, and black soybean. The phytic acid content of brown rice was five times higher than those of 100% polished rice. The polishing process of the rice decreased significantly the content of the phytic acid. We estimate that the daily phytic acid intake from rice was changed from 653 mg/day in 1995 to 430 mg/day in 2005 based on the results of a national nutrition survey.
