After heated discussion, National Police Agency decided not to install Red Arrow signal at such major intersections as Gwanghwamoon, Sejongro. The major issues can be summarized in the following reasons. The one is the conflict of color and symbol (red means STOP and arrow means PROGRESS), and it would confuse drivers and may cause traffic accident. The other includes high replacement cost. This paper delivered how much red arrow signal would affect (1) drivers start up delay time, (2) saturation flow rate and (3) vehicle headway. The result showed that there was no statistical difference in those even when a red arrow signal is placed.

According to the statistics of the National Police Agency, red light running (RLR) crashes represent a significant safety issue throughout Korea. This study deals with the RLR crashes occurred at signalized intersections in Cheongju. The objectives of this study are to comparatively analyze the characteristics of between RLR crashes and the Non-RLR crashes, and to find out factors using a Binary Logistic Regression(BLR) model. In pursuing the above, the study gives particular attentions to testing the differences between the above two groups with the data of 2,246 RLR/ 3,884 Non-RLR crashes (2007-2011). The main results are as follows. First, many RLR crashes were occurred in the nighttime and in going straight. Second, the difference between RLR and Non-RLR crashes were clearly defined by crash type, maneuver of vehicle before crash, age of driver (30s, 50s), alcohol use and accident pattern. Finally, a statistically significant model (Hosmer and Lemeshow test : 7.052, p-value : 0.531) was developed through the BLR model.

Objective : To investigate the effectiveness of radiographic parameters on segmental instability in the lumbar spine using Kinetic magnetic resonance imaging (MRI). Methods : Segmental motion, defined as excessive (more than 3 mm) translational motion from flexion to extension, was investigated in 309 subjects (927 segments) using Kinetic MRI. Radiographic parameters which can help indicate segmental instability include disc degeneration (DD), facet joint osteoarthritis (FJO), and ligament flavum hypertrophy (LFH). These three radiographic parameters were simultaneously evaluated, and the combinations corresponding to significant segmental instability at each level were determined. Results : The overall incidence of segmental instability was 10.5% at L3-L4, 16.5% at L4-L5, and 7.3% at L5-S1. DD and LFH at L3-L4 and FJO and LFH at L4-L5 were individually associated with segmental instability (p<0.05). At L4-L5, the following combinations had a higher incidence of segmental instability (p<0.05) when compared to other segments : (1) Grade IV DD with grade 3 FJO, (2) Grade 2 or 3 FJO with the presence of LFH, and (3) Grade IV DD with the presence of LFH. At L5-S1, the group with Grade III disc and Grade 3 FJO had a higher incidence of segmental instability than the group with Grade I or II DD and Grade 1 FJO. Conclusion : This study showed that the presences of either Grade IV DD or grade 3 FJO with LFH at L4-L5 were good indicators for segmental instability. Therefore, using these parameters simultaneously in patients with segmental instability would be useful for determining candidacy for surgical treatment.

In this paper, we analyzed current states and spatial characteristics of crime occurring in A city of Colombia using big data of crime. The analysis draws on the crime statistics of Colombia National Police Agency from 2013 January to September. We also investigated spatial autocorrelation of crime using global and local Moran's Index. Spatial autocorrelation analysis shows significant spatial autocorrelation in the high frequency of crime. Global Moran's I analysis indicates that there are statistically significant value of crime area. Using local Moran's Index analysis, we also implement Local Indicators of Spatial Association(LISA) map and hot spot analysis helps us identify crime distribution.

2004 summer, most of Korean were shocked from serial killer Ryo young chul's criminal behavior. He had kept anger to society and selected the victim randomly. He killed many females and senior persons. Korean National Police's investigation method to homicide depend on traditional homicide investigative methods. But serial killer's criminal behaviour is evolving frequently. Therefore traditional investigative method is no effective to serial homicide anymore. If traditional investigative method is old version virus vaccine, serial killer's criminal behaviour is newly appeared computer virus. Fortunately all of criminal has modus operandi independently. Any person comes into contact with an object or another persons, a cross-transfer of physical evidence happens. In the future it is impossible to escape from confrontation with serial killer. It can be prospect that more severe copycat serial killer will appear in Korean society. Based on the Ryo young chul's criminal behavior. I'll try to analyse the serial killer's modus operandi through various aspects.

Last year, over 800 Australian live cattle were imported, underwent quarantine procedure for one month in the port of Incheon and Busan and distributed to general farm house holds in Gyeongju city, Gyeongbuk province, and Gimhae city, Namhae county, Gyeongnam province. But Hanwoo association took violent actions to prevent from entering the country for fear that the imported live cattle would destroy the 'Hanwoo industry', and in turn leads to the collapse of the industry. In Australia, national animal protection body 'Animals Australia' investigated the level of cruelty involved in this trade and made a report 'The death file'. Australia governments drive to expand Its market for 'live animal exports' and it has resulted in a corresponding increase In casualties associated with the long-haul overseas trade in live livestock animals over the past years. After the stress of transportation, all the surviving cattle and sheep face death on foreign soil, many into countries which have no animal welfare laws or, at best, inadequate laws. They will usually be killed without pre-stunning and often even without adequate restraint facilities. The result is inherent and persistent suffering. West Australian(WA) Police acting on behalf of the West Australian Government and the Office of the WA State Solicitor have laid animal cruelty charges against a leading WA live export company for breaching the WA Animal Welfare Act. With the aim of eventually substituting it for the live sheep trade, the Senate Select Committee on Animal Welfare (SCCAW) recommended that the Federal Government 'promote and encourage the expansion of the refrigerated sheep meat trade to the Middle East and other countries'. Animal welfare standards have been improved time after time, there is another incident, another public outcry, another inquiry and more assurances.

Improvement of roadway environments to accommodate elderly drivers' declining driving capabilities are required. Currently, even the types of roadway designs vulnerable to elderly drivers have not been revealed in Korea. Thus, this study aims to analyze the types and vulnerabilities of the roadway designs that elderly drivers experience more accidents based on crash data of the Korean National Police Agency. This study has also reviewed foreign guidelines enhancing their safety on different roadway designs. Compared with normal drivers, elderly drivers tend to be more frequently involved in traffic accidents on intersections and vehicle-to-vehicle accidents on curved roadway segments. Assuming freeway interchanges are also risky sections, this study has also examined several methods to reduce elderly driver-related accidents on freeway ramp areas.

The national police agency has executed the project for the advancement of traffic control and operation systems in order to mitigate chronic traffic problems and to meet the global standards regarding the traffic control and operation systems. This study effort was initiated to evaluate the effects of various policies proposed for the advancement of traffic control and operation systems. The evaluation results indicated that the policies proposed for the advancement of traffic control and operation systems showed apparent and positive effects in terms of transportation mobility and safety. However, there have been many difficulties to overcome in order to settle down the policies proposed for the advancement of traffic control and operation systems as smooth as possible. For example, the violation of intersection passing method has been increased after the implementation of the advancement of traffic control and operation systems in majority of evaluation sites. In addition, lacks of awareness as well as improper operations of the advancement of traffic control and operation systems have caused drivers' confusions, which generated more traffic congestion and risks. Currently, the policies for the advancement of traffic control and operation systems focused on the improvements of traffic signal operations, including leading through movements and permissive left-turns. However, synergy effects may be expected if all of the policies including the improvements of traffic signal operations are executed together.
