This study examined spatial disposition of wildlife highway mortality using road-kill GIS database and Naver panoramic 360 degree views to find out which habitat and road variables most influenced road-kill numbers for each mammal species and how the landscape and road elements are connected on highway. Road-kills on Yeongdong(YD) and Jungbu highway(JB) generally tended to be higher in natural barren, grassland and cropland due to its value of preferred habitats of nocturnal and multihabitat species like water deer(Hydropotes inermis argyropus), raccoon(Nyctereutes procyonoides) and hare(Lepus coreanus). Land cover in YD showed no difference between species (p=0.165) while JB did by species (p=0.001). This may be explained by disparate landscape between mountain and urban or the fact that YD in long term operation might have enabled consistent crossing pattern compared to JB experiencing continuous extension works which may in turn have deviated the road crossing. Although road-kill prevention effect of local topography alone was appreciable, compared to less significant or ineffective fence and guardrail, gentle slope declining in a direction to the road turned out to offset the preventive effect of juxtaposed fence. Furthermore, green patches on road near intersection were deemed a visual stepping stone facilitating wildlife attempted crossing and local roads juxtaposed with a highway were especially left defenceless to road-kill without road barriers.

This thesis is about the system where the solar module is attached to the high functional guardrail posts with anti-weed, anti-plant, and road-kill applied to produce internal power, enabling the integrated control and real-time monitoring of appearance of wildlife and road conditions using the USN. The whole system consists of a photovoltaic module(PV), a detection sensor(pyroelectric), a controller(operation select and motion sensor), the USN system, the DB(sound and flash), an output unit of sound and flash, and the control system of road-kill prevention and safety induction for vehicles. Thus this study aims to address the remote control and monitoring system of multipurpose guardrails to improve road environment, prevent road-kills, protect wild animals, and guide cars safely by using the USN which is combined with new renewable energy and IT convergence technology. As a result of the study on the remote control and monitoring system using the USN, it was ascertained that the response time of the unmanned sensing system was within 5.1 ms with the current consumption of 0.328 mA, and the data transmission speed of the remote control system was 250 kbps with the current consumption of 0.283 mA.

Hongdo and Huksando belong to the Dadohae national park parks in Korea and are famous sightseeing spots in Shinahn-gun. One of the keystone species in this area is otter (Lutra lutra). We accomplished field works for finding its present habitat and condition analyses for the potential habitat in the area via spatial analyses with digital elevation model and satellite imagery. Isolated condition with coastal cliffs was one of the superior conditions over habitat in the main land, but the road kills of small animals were also observed. Three underground eco-corridors were suggested for the protection of otter habitat in the Shinahn-gun area. Regional development strategies of Shinahn-gun should be focused on the protection of safe and pristine habitat for otter population.

The objective of this paper was to investigate the potential of road-crossing structures as biological corridors that can overcome wildlife habitat fragmentation caused by road construction. Snow tracking on animal trace adjacent to and under bridges, underpasses, and culverts of eight rural highways in Korea was carried out. A total 89 structures were monitored and the results follow. First, the probability of road crossing increases with the increasing cross sectional size of crossing structures. Second, small to medium sized carnivores such as raccoon dog, leopard cat, and Siberian weasel use all types of structures. Finally, water deer, or large herbivore crossed only under bridges. Consequently, further studies are necessary to identify suitable types of road crossing structures that can mitigate the probability of road-kills and habitat fragmentation of water deer.

This study aims to assess habitat feature on the large-scale spawning ground of the Boreal Digging Frog Kaloula borealis in Daemyung retarding basin of Daegu, and to analyze the relationships between species abundance and meteorological factors for each habitat. Fifty-seven(57) pitfalls were installed to collect species abundance of 4 survey regions, and high-resolution satellite image, soil sampling equipment, digital topographic map, and GPS were used to develop habitat features such as terrain, soil, vegetation, human disturbance. The analysis shows that the frog is most abundant in sloped region with densely herbaceous cover in southern part of the retarding basin. In the breeding season, lowland regions, where Phragmites communis and P. japonica dominant wetlands and temporary ponds distributed, are heavily concentrated by the species for spawning and foraging. Located in between legally protected Dalsung wetands and lowland regions of the retarding basin, riverine natural levee is ecologically important area as core habitat for Kaloula borealis, and high number of individuals were detected both breeding and non-breeding seasons. Temperate- and pressure-related meteorological elements are selected as statistically significant variables in species abundance of non-breeding season in lowland and highland regions. However, in sloped regions, only a few variables are statistically significant during non-breeding season. Moreover, breeding activities in sloped regions are statistically significant with minimum temperature, grass minimum temperature, dew point temperature, and vapor pressure. Significant meteorological factors with habitat features are effectively applied to establish species conservation strategy of the retarding basin and to construct for avoiding massive road-kills on neighboring roads of the study sites, particularly post-breeding movements from spawning to burrowing areas.

In 2019, a child died by a school zone traffic accident in Asan, Chungcheongnam-do, the Republic of Korea. Just after the accident, under the name of the "Minsik Law", the Road Traffic Act and the Specific Crime Aggravated Punishment Act were partially revised and went into effect in Korea on March 25, 2020. The new Korean law providing for harsh penalties is designed to reduce automobile accidents in school zones. However, the penalties under the new law seems to be unconstitutionally and unduly harsh. Under the new law, a negligent driver who kills a child at a school zone could be sentenced to indefinite imprisonment, or imprisonment for 3 years or more. The criminal responsibility of a negligent driver at a school zone is the same as serious intentional felonies such as rape, robbery, abandonment resulting in death. Also, even in the case of a school zone accident, if an accident driver complies with the speed limit and other traffic laws and it is impossible to avoid the accident, the driver should not be punished. So, in order to meet the principle of proportionality, the new Korean law should be revised again. In order to find out the appropriate level and punishment method for drivers who cause accidents in school zones, this thesis will compare and analyze the laws of Korea with those of the United States, Germany, and Japan. This paper also reviews the decision of the Constitutional Court of the Republic of Korea in February 2023 that the "Minsik Law" was constitutional. Based on these analyses, this thesis seeks the direction and amendments to properly revise Korean law. In addition, this thesis is intended to present exemplary measures to improve the school zone safety.
