In the case of the cooperative intelligent transportation system (C-ITS), one of the advanced technologies to improve the drivability of existing vehicles and driver safety, including commercial vehicles, we need additional consideration of the C-ITS service at the driver level. In particular, it is necessary to identify and improve C-ITS functions and service issues at the HMI level in advance through scenario development and driver reaction simulation. In this paper, we developed C-ITS driver HMI scenarios. For the development, we first investigated the current C-ITS service and in-vehicle HMI analysis for driver scenarios. We also measured the driver's reaction speed using Simio simulation. Given our analysis, we developed service blueprinting maps for commercial vehicle drivers, including user journeys, and we analyzed C-ITS services from various user HMI perspectives.

The purpose of this study is to classify the types of street parking in low-rise residential areas. First of all, prior research was reviewed to examine the background of occurance and the process of change of low-rise residential areas. and derive factors that affect the street environment. Next, based on the selection criteria, the residential area of Bangi 2-dong, Songpa-gu was selected as the site of the case and the status analysis was conducted on streets, buildings, and on-road parking. The summary of the results is on-road parking usually occurs on residential streets where social consensus is difficult to reach, suggesting that alternatives to on-road parking in residential areas are needed. Based on the results of the previous analysis, street types were classified considering the characteristics of streets, structures and street parking. Then, the characteristics of each type of street were analyzed and implication for improving the street environment were suggested. In addition, the results of the classification of street types confirmed that different street parking occurred depending on the width of the street and the use of the lower floors, even if it was the same area, and that a solution was needed accordingly.

This study is a descriptive and exploratory one aiming to develop a systematic/diagnostic manual that is necessary for the improvement of the pedestrian safety of a neighborhood and show the practical application and usefulness of the manual through a case study. The diagnostic manual developed on the basis of the previous research review adopted a mixed research method including three investigation tools of map/data analysis using secondary data, field observation by investigators, and resident survey interview. In the case study applying the manual to Changsin-dong, Seoul, the author analyzed the results of the three investigations in integrative ways and showed the usefulness of the manual by systematically deriving the places prone to pedestrian-vehicle accidents and the influencing factors. This study contributes to the practical field in that it provides planners with a systematic tool to diagnose the pedestrian safety in the neighborhood environment while it contributes to the academic field in that it provides the concrete process that empirically compares the differences between different environmental investigative methods and deduce integrative implication from them. In a follow-up study, the author plan to apply the diagnostic manual presented in this study to more cases and improve them to work in various contexts. [ABSTRACT FROM AUTHOR]

‘Dahye’, a new covered cultivar derived from the crosses between ‘Suwon318' and‘Suwon311' developed at the Honam Agricultural Research Institute (HARI), NICS, RDA in 2007. The initial crossing was made in 1996 and an elite line, ‘SB964008-B-B-B-92' was selected from under yield trial test in 2004. It was designed as ‘Iksan409' and showed a high yield and had good quality in the regional yield trials (RYT) from 2005 to 2007. It was released with the name of ‘Dahye’.‘Dahye’had a rate Ⅲ growth habit, green leaf and stem, compact spike and long rough awns. The heading date was April 29 in upland and April 20 in paddy field, which was 2 and 5 days earlier than that of check cultivar,‘Olbori', respectively. It had 88 cm of culm length, 4.2 cm of spike length and 666 spikes per m2, 52 grains per spike, 35.6 g of 1,000-grain weight and 702 g of test weight. It showed stronger winter hardiness and higher resistance to barley yellow mosaic virus (BaYMV) than those of check cultivar. It had similar protein content with check cultivar and higher whiteness and diastatic power (DP) than those of Olbori. The average yield of the pearled grain in the regional yield trial (RYT) was 4.00 ton ha-1 in upland and 4.11 ton ha-1 in paddy field. This cultivar would be suitable for the area that the daily minimum mean temperature is above -8℃ in January in Korean peninsula. [ABSTRACT FROM AUTHOR]
