This paper studies changes in people's social security awareness during Lee Myung-Bak government, and based on the result, suggests future Park Geun-Hye government's social-security-related administration management plan. In specific, the changes in people's social security awareness in the period of 2008 ~ 2012 have been analyzed, and the result has been utilized to draw suggestions on the future social-security-related administration management plan The result is as the following: First, comprehensive social-security-related policy must be continuously pushed. In terms of the fact that social security is closely related to people's daily lives and life itself, every major component of social security cannot be overlooked. Therefore, comprehensive administration management and policies on each of those components are necessary. Second, social security policies must be reinforced enough for people to actually witness. In case of crime rate, 57.1% of people are pointing it as one of the main causes of social unrest; therefore, this national anxiety must be met with focusing awareness on the subject nation-widely and with thorough national defense preparedness. Third, mutual cooperation between social-security-related branches, and systematic management within the each branches are required. In order to systematically manage every aspect of social security, not only the big agencies - such as Ministry of Security and Public Administration, Ministry of National Defense, Prosecution Service, or National Police Agency -, but most of other parts of administration must cooperate as well. Fourth, consistency in social security policies is necessary. As Park Geun-Hye government's administrative slogans are, "secure and integrated society," "establishing a foundation for happy unification era," which are similar to that of previous administration, the administration should be consistent on its social-security-related politics, rather than differentiating themselves from the previous administration.

Researchers have used the visual criteria to compare the effectiveness of fingerprint enhancement techniques. However, since the visual criteria is subjective, bias can occur. Therefore, many researchers have tried to make the criteria objective using the contrast index (CI). However, there is a constraint that the CI was only validated on inked fingerprints or color-change fingerprints. In this study, we compared enhancement of fluorescence fingerprints on colored papers using the CI. The CI values differ according to the color of the background, reagent, and light source, even though the same standard fingerprints were used. Through the comparison of values, we could compare the enhancement of fluorescence fingerprints according to these factors. When visual evaluation criteria were used, the same peak score was obtained regardless of the reagent and light source. However, we could get a more detailed score comparison in this study using the CI. Therefore, it is confirmed that for comparison of enhancement of fluorescence fingerprints, the CI can be used as a basis for determining which light source and reagent are appropriate according to the background.

The objective of this study was to understand the degree of conflict in team teaching nursery teachers and also differences in conflict management methods and job satisfaction in accordance with conflict level. For this, a survey was conducted targeting 241 team teaching nursery teachers. In the results of the study, conflict management methods in accordance with conflict level of team teaching nursery teachers showed significant differences in the type of 'integration' and 'avoidance' between groups. Second, job satisfaction in accordance with the conflict level of team teaching nursery teachers showed significant differences in the whole like 'director's operation method & attitude', 'social perception & treatment', 'childcare environment and welfare', 'childcare work', 'relation with colleagues', and 'relation with parents' between groups. In other words, the group with low conflict showed higher job satisfaction than groups with middle or high conflict levels. Based on the results of the study, the efficient operation of team teaching nursery teachers was also discussed.

PURPOSES: According to accident statistics for road built in 2004, the ratio of accidents on frozen roads to normal roads is 0.9%, whereas the fatality ratio is 2.7%. The risk of accidents on frozen roads is very high. Measures taken every year to prevent traffic accidents of frozen roads in the winter season are still insufficient. Additionally, measures have been established mainly on rural roads. Therefore, for urban roads, analyses and measures to prevent accidents are lacking. In this study, data on accidents on frozen roads was used to search for the causes behind these accidents and measures to reduce accidents have been recommended. METHODS: In this study, collected data from the TAMS (Traffic Accident Management System), which were collected by the Seoul National Police Agency was used. The data were divided into vehicle, people, and condition of road. The analytical model used here was the Logistic Regression Model, which is frequently used for traffic safety and accident analysis. This study uses the odds ratio analysis to search for variables related to frozen road traffic accidents in each category. A total of 18 out of 47 variables were found to be the causes of accidents. RESULTS: From the results of the comparative analysis of 18 variables, the category of the condition of the road was found to be the most critical. Contrary to expectations, more accidents occurred in clear weather than in other conditions. Accidents on bridges occurred frequently, and its odds ratio was the highest compared with other road types. When BPT is operated, the probability of accidents on frozen roads is lower than in general conditions, and accidents occurred frequently on roads with less than four lanes. CONCLUSIONS : Based on the results of this study, suggestions for reducing the risk of future domestic road accidents in freezing conditions are indicated as follows. First, it is necessary to perform a technical review of the urban road traffic accidents caused by frozen roads. Second, it is necessary to establish criteria for the study of the road environment based on the major causes of road accidents on frozen roads. Third, improvements in urban road environmental factors should be made.

In order to reduce traffic accidents at long road sections involving high risks of traffic accidents, including tunnels, bridges or curves, the National Police Agency have decided a tentative installation and operation of an automated point-to-point speed enforcement system based on cameras at January, 2007. The first system was established at the direction to Kangreung of Dunnae Tunnel at December, 2007. Currently, the automated point-to-point speed enforcement system operates at 11 sections including eight sections on expressways and three sections on national highways. However, there have been few researches on the effects of the system upon the reduction of traffic accidents in a scientific way. To this end, this research effort was initiated to evaluate the effect of the automated point-to-point speed enforcement system on traffic safety by comparing the number of traffic accidents before and after the installation of the system using a comparison-group(C-G) method. Three-year-long traffic accident data for the expressways were collected in order to evaluate the system. As a result, the installation of the system was found to reduce traffic accidents by 49.97% in average.

This study aims to propose efficient way to operate the security guarding system from the perspective of administration, policy, law, institution and operation as to the private security guarding system as the Korean security guarding system needs multifaced analysis and measure to ensure efficient operation. The growth strategy has to be restructured and segmentation market needs to be driven in order to cope with the changing conditions of company from the perspective of administration. And private security guarding service companies must refrain from excessive competition while improving the contracting method such as minimum price bidding, etc. From the perspective of policy, the functions of relevant organizations such as the National Police Agency, security association, etc, and mutual cooperation must expand. Also, the profit generation event needs to be privatized and the more positive perception toward the private security guarding service is necessary. In addition, security exhibition and seminar can be expanded to lay the groundwork for the advancement of private security system. From the legal and institutional perspective, the security guarding service related law must be revised and the certification system must b introduced to cope with the changing requirement. The security guarding instructor system must be strengthened to ensure a faithful and earnest implementation of duty to instruct, supervise and educate security guarding personnel. From the perspective of security guarding system's operation, professional security technique must be introduced and applied, and the volunteer application system must be established. In addition, standard 'security guarding manual' must be crafted, and the equipment for security guarding must be modernized to ensure an efficient operation of private security guarding services.
