This study aims to analyze the causes of the disabled people's fear of crimes and to provide the implication to relevant policies. For this, we scrutinize how the disabled perceive the fear toward felonies and the police action. Further, we empirically tested how police action and their recognition toward it affects the fear toward crimes, on the basis of collective efficacy and victimization which is believed to have effects on people's fear of crimes. As the physically disabled are incompetent to respond to the questions, we survey 122 person with physical disability for 25 branches of Seoul Association of Person Physically Disabled. Our regression results show negative correlations between collective efficacy and fear of crimes, which is in accord with preceding researches of the non-handicapped. While indirect victimization shows positive correlations with their fear toward crime, it is ot statistically significant in conventional confidence level. Contrarily, direct victimization shows positive correlation with it, and the coefficient is different from zero in conventional level. As it is proven from preceding studies, confidence in police action and their perception toward it has negative correlations with their fear of crimes.

Background: Police work is generally sedentary although there may be situations that require physical endurance and strength, such as foot chases and arresting suspects. Factors such as excessive body fat can impede an officer's physical ability to deal with such occurrences. Our objective was to examine associations between officers' body fat percentage (BF%) and performance on a standardized fitness protocol. Methods: Data were obtained from fitness screening among 1,826 male and 115 female officers in a large US police agency. The screening consisted of a 2.4-km run, push-ups, sit-ups, and sit-and-reach test. Sex-specific body fat percentages were estimated from skinfold thickness measured using calipers. Linear regression models were used to examine unadjusted and adjusted mean scores of fitness tests across BF% tertiles. Results: The prevalence of overall fitness was 4.3 times greater in male officers and 3.6 times greater in female officers having the lowest BF% tertile compared with the highest tertile (30.3% vs 7.1% and 46.0% vs 12.8%, respectively). BF% was linearly and positively associated with the time of 2.4-km run (p < 0.001), and linearly and inversely associated with the number of push-ups (p < 0.001), sit-ups (p < 0.001), and the distance of sit-and-reach (p < 0.001) in men. Similar associations were observed in women with the exception of sit-and-reach (p = 0.122). Associations were independent of age, race/ethnicity, rank, and duty station. Conclusion: Overall, BF% was inversely associated with fitness levels in male and female officers. Future longitudinal studies should be initiated to explore the potentially causal relationship between BF% and fitness in law enforcement officers.

This thesis attempts to provide a foundation for effective preventative education of middle school students regarding school violence after identifying the level of perception of school violence as well as analyzing perception of preventive education among students. The study compiled data on 474 middle school students from middle schools in Jeollanamdo. The findings of the study are as follows. First, most of the students were aware of the necessity for preventive education regarding school violence. By gender, girls and those of lower grades showed great class participation and satisfaction. Second, research on the preventive education found differences in the seriousness of school violence according to school location. Fourth, preventive education conducted once or twice a month was the most desirable condition for middle school students. As a result, schools should consider gender differences and grade level when, developing an education program in order to prevent school violence.

This paper describes Listening Decision Aid Simulator (LDAS) to provide a decision-supporting tool that can reproduce real-like listening situations focused on the duty officer's two ears. The sound propagation mechanism from a whistle to listener's two ears is established at first, and the spatial transfer coefficients of a bridge door are measured at training vessel. Then, the construction works with the spatial transfer coefficients and its evaluation experiments with five collision accidents are carried out. As results from tests, the five cases can be judge by LDAS; it led to the insight of practical use of LDAS as one of the decision supporting system in collision accidents.

The changed environment on marine security and the security activities such as coast guard and sea patrol in civil domain are analyzed. In order to respond diverse threats and requirements of sea petrol, the system of civil patrolman and coast guard's auxiliary are discussed. The civil boats and aircraft and civilian's security activities make an important role to enhance the effectiveness and the efficiency of coast guard and patrol.

The system of civil security service is analyzed and reviewed in order to induce it to maritime security domain. A system of civil maritime guarder who provides security service and cooperates with coast guard at sea is proposed. It is expected not only that some expecters on the field of maritime security service are built up but that the Qualities of security services are improved in considering characteristics of sea control and coast guard.
