Wind-drag estimation in a traffic accident involving a motor scooter and a tractor-trailer

This case report describes a noncontact traffic accident involving a motor scooter and a tractor-trailer with a focus on the wind-drag effect. We used load cells to measure the drag force acting on a substantially similar motor scooter when a substantially similar tractor-trailer passes by it, taking into consideration various speeds of the tractor-trailer and distances between the two vehicles. A three-dimensional steady-state flow analysis was also performed by using the CFX program for computational fluid dynamics to examine the streamlines and the pressure distribution around the tractor-trailer at various speeds. From the experiment, for a separation distance of 1.0 m (3.28 ft) and a speed of 90 km/h (55.9 mph), the maximum resultant drag force is 124.5 N (28 lb); this constitutes a degree of force that could abruptly disrupt the stability in maneuvering by an operator who is unaware of the approaching tractor-trailer. In addition, a single equation that relates the tractor-trailer speed to the drag force that acts on the motor scooter was derived on the basis of the Reynolds number (Re) and the wind-drag coefficient (C(d)): C(d) = 1.298 × 10(-7) Re.     

Measuring the crime displacement and diffusion of benefit effects of open-street CCTV in South Korea

Crime prevention strategies are implemented to reduce the damage caused by crimes with CCTV (Closed-Circuit Television) being broadly accepted as one of the main strategies. However, along with CCTV's perceived high expectations as crime deterrent, there is also a growing controversy over CCTV's potentially unexpected limitations. For example, the crime displacement (the presence of CCTV will change the locations of crime and its total number will not change) and the diffusion effects of crime control benefits (the crime prevention effect of CCTV may filter through to neighboring areas) are the representative controversial issues. In this study, we aimed to verify the crime displacement and the diffusion of benefit of open-street CCTV by analyzing the crime tendencies empirically.Gwang Myeong City in Gyeonggi Province, South Korea was chosen to analyze the crime displacement using the WDQ (Weighted Displacement Quotient) which compares the crime tendency of a location with that of its neighboring areas. The results showed that the crime prevention effect of the CCTV was significant. The number of robberies and thefts in the areas with CCTV installed reduced by 47.4%, while the areas without CCTV showed practically no change in the number of crimes. The crime displacement caused by the CCTV was not either found or inconsequential, and the crime rates in the neighboring areas also decreased slightly. Of major cause for concern was the fact that CCTV was marginally effective in deterring violence and as such, there should be a more detailed scientific analysis of the pattern and type of crimes committed in an area where CCTV's are being installed.     

Pedestrian accident analysis with a silicone dummy block

When a car is parked in an inclined plane in a parking lot, the car can roll down the slope and cause a pedestrian accident, even when the angle of inclination is small. A rolling car on a gentle slope seems to be easily halted by human power to prevent damage to the car or a possible accident. However, even if the car rolls down very slowly, it can cause severe injuries to a pedestrian, especially when the pedestrian cannot avoid the rolling car. In an accident case that happened in our province, a pedestrian was injured by a rolling car, which had been parked on a slope the night before. The accident occurred in the parking lot of an apartment complex. The parking lot seemed almost flat with the naked eye. We conducted a rolling test with the accident vehicle at the site. The car was made to roll down the slope by purely gravitational pull and was made to collide with the silicone block leaning against the retaining wall. Silicone has characteristics similar to those of a human body, especially with respect to stiffness. In the experiment, we measured the shock power quantitatively. The results showed that a rolling car could severely damage the chest of a pedestrian, even if it moved very slowly.     

Facial Soft Tissue Thickness Database for Craniofacial Reconstruction in Korean Adults

Abstract: One hundred Korean adults (50 men, 50 women) were scanned in the upright position using a cone‐beam CT (CBCT) scanner. The soft tissue (ST) thicknesses were measured at 31 landmarks, 10 midline and 21 bilateral landmark sites, and the means and standard deviations were obtained for male and female subjects. While 18 of 31 landmarks showed sex differences, the majority showed higher values for male subjects with the exception of a few landmark sites corresponding to the zygoma area, which showed smaller values in men than in women. The mandibular area showed greater differences between the right and left sides. Overall, the ST thickness measurements obtained in this study can be used as a database for the forensic craniofacial reconstruction of Korean adult faces.

Be Careful What You Wish For: Security Challenges Facing the Korean Peninsula During a Potential Unification Process

There is a lacuna in the literature analyzing the mid-term (6-24 months) period after a DPRK contingency that results in the Pyongyang regime’s relatively sudden and unmanaged fall. This article helps fill that gap, particularly with respect to security issues that would challenge Korean unification efforts during such a period. Following an Introduction, Section I first makes the case for a DPRK contingency being the most plausible end to the Pyongyang regime. Assuming the scenarios from Section I, Section II addresses the question of what critical issues a unifying Korea will face over the mid-term, and how dealing with these challenges will condition the type of end-state that a unified Korea will embody. In particular we examine three challenges: (a) mid-term security provision related to potential weapons proliferation, cyber-security, organized criminality, and human security; (b) the foundations of institution-building through measures dealing with issues of transitional justice, disputed land title claims, and generating broad domestic stakeholder buy-in in a unifying Korea; (c) the disposition of Korea’s strategic alignment in a Northeast Asia that will have undergone a major alteration of the regional system. Section III concludes with policy recommendations concerning what efforts should be made now to prepare for the situations described in Sections I and II.     

Drivers of Policy Instrument Selection for Environmental Management by Local Governments

Local governments commonly pursue environmental objectives that exceed state and federal minimum requirements. Although research informs our understanding of factors that lead cities to adopt such policy goals, the underlying mechanisms employed to achieve them are not well understood. This article examines factors that drive the choice of policy instruments that cities use to pursue local environmental objectives. The literature links the structure of the local governing body, characteristics of the community and target populations, and the nature of the policy problem to instrument selection. Building on this, the authors model the dynamics shaping cities' use of regulations, financial incentives, or combination thereof, to pursue a variety of different environmental objectives. Results indicate that community racial composition and political leaning influence instrument choice when policy targets the public at large. Alternatively, when policy targets particular stakeholder groups, such as developers, the characteristics of the local governing body are of greater importance.     

Administrative reorganization as a signal: Bounded rationality,agency merger,and salience of policy issues

Although administrative reorganization has been a major political instrument in many democracies, there has been limited research on its effects. Aiming to address this gap, this study examines the reorganization of Korean government ministries, specifically, the impact of reorganization in the form of a merger of ministries performing interrelated but dissimilar functions. Examining the salience of policy issues expressed in official government press releases during the 12‐year period from 2001 to 2012, we found that administrative reorganization in the form of a merger has a significant impact on the relative salience of government policy agendas. Specifically, the interrupted time series estimates indicate that the salience of science and technology policy issues (in relation to education policy issues) decreased by approximately 12% to 17% following the dissolution of the Ministry of Science and Technology. We explain this finding based on the bounded rationality view of bureaucratic information processing.
