It is essential to increase the implementation rate in order to increase the effectiveness of mitigation measures that can mitigate the negative impact of development projects. In the case of Environmental Impact Assessment (EIA),research on the implementation evaluation of development projects is insufficient, even though the effectiveness of mitigation measures has been steadily raised. Therefore, this study evaluated the implementation rate of the mitigation measures and identified the cause of the difference in the implementation rate for each mitigation measures in order to understand the current status of the ecological mitigation measures. The implementation rate of urban and road development projects mitigation measures was 56.0% and 64.4%, respectively. the implementation rate of 'Monitoring' mitigation measures was the highest in all development project. But, 'Habitat creation' and 'Accident prevention measures' were low. In addition, it was found that the implementation rate of the mitigation measures were high when the contents of the mitigation measure described in the report were specific. Through this study, it was found that in order to increase the implementation rate of the EIA ecological environment animal mitigation measures, it is necessary to reflect the environmental and geographical characteristics of the target site in detail. Furthermore, it is judged that this study can be used as a basic basis for enhancing the effectiveness of the EIA system introduced to mitigate the negative impact on the environment.

The concrete median barrier used currently in South Korea was developed the impact level of SB5-B(270kJ). However, the impact level of SB6(420kJ) should be considered in many placed with the increased accident of heavy vehicles. In order to increase the impact resistance of newly developed concrete median barrier, the computer simulation was conducted before real field test. For the accurate behavior of concrete, the parameter, such as impact vehicle, concrete cover depth and deterioration, was important. In this paper, a parametric study was conducted depending on vehicle curb weight, concrete cover depth and level of deterioration. The impact resistance of concrete median barrier was severely changed depending on vehicle curb weight and concrete cover depth. Furthermore, the impact resistance of concrete median barrier was also decreased due to deterioration of concrete, therefore the repair and rehabilitation should be conducted for damaged concrete depending on deterioration level. Therefore, vehicle curb weight, cover depth of concrete structures and deterioration level of concrete should be carefully considered for conducting analysis of concrete structure to vehicle collision.

Purpose: The COVID-19 pandemic led to significant changes in the lifestyle patterns of children and affected the patterns of pediatric injuries. This study analyzed the changing patterns of pediatric injury overall and by age groups, based on the datasets before and during the COVID-19 pandemic. Methods: This study is based on the data of patients who presented with injuries at 23 hospital emergency departments participating in the Emergency Department-based Injury In-depth Surveillance (EDIIS) conducted by the Korea Disease Control and Prevention Agency. The surveillance data was categorized by injury mechanism, location, activity, and severity. We analyzed the injury patterns of pediatric patients aged 0 to 15 years. Subgroup analysis was conducted by age group in children aged 7 to 15 years, 1 to 6 years, and <1 year. Results: When comparing the COVID-19 pandemic period to the pre-COVID-19 period, the total number of pediatric patients with injuries decreased by 38.7%, while the proportions of in-home injuries (57.9% vs. 67.9%), and minor injuries (38.9% vs. 39.7%) increased. In the 7 to 15 years group, bicycle riding injuries (50.9% vs. 65.6%) and personal mobility device injuries (2.4% vs. 4.6%) increased. The 1 to 6 years group also showed an increase in bicycle accident injuries (15.8% vs. 22.4%). In the <1 year group, injuries from falls increased (44.5% vs. 49.9%). Self-harm injuries in the 7 to 15 years group also increased (1.6% vs. 2.8%). Conclusions: During the COVID-19 pandemic period, the overall number of pediatric injuries decreased, while injuries occurring at home and during indoor activities increased. Traffic accidents involving bicycles and personal mobility devices and self-harm injuries increased in the 7 to 15 years group. In the <1 year group, the incidence of falls increased. Medical and societal preparedness is needed so that we might anticipate these changes in the patterns of pediatric injuries during future infectious disease pandemics.

This study analyzes the risks of explosions of small LPG storage tanks installed at highway rest areas. For this purpose, the ranges of the effect of thermal radiation and overpressure caused by the BLEVE(Boiling Liquid Expansion Vapor Explosion)and VCE(Vapor Cloud Explosion) of a 2900-kg small LPG storage tank installed at highway rest areas were quantitatively evaluated by applying the Areal Location of Hazardous Atmospheres program. The ranges of influence of the derived explosion overpressure and thermal radiation were found to have a maximum radii of 336 m and 423 m, respectively. The study determined that those within 269 m could be severely injured by an explosion overpressure of 3.5 psi, and fatalities from thermal radiation of 10 kw/m² could occur within 192 m of the exploded storage tank. The safety management plan for the LPG storage tank was discussed while considering the auxiliary facilities of highway rest areas and the extent of the damage impact. These research results will help improve safety accident prevention regulations considering the environment and facilities of the rest areas as well as the safety management of small LPG storage tanks installed at highway rest areas.

Motorcycle patrol is used for traffic control and enforcement in highly congested areas. One of the major problems with this form of patrol is that it is extremely dangerous since just about any type of accident tends to cause harm to the rider. The purpose of this study is to analyze the effectiveness of police motorcycle patrol, and to suggest the methods for improving the effectiveness of police motorcycle patrol. This study conducts the survey on 139 policemen that belong to Daejeon Provincial Police Agency that had implemented motorcycle patrol. By factor analysis, the intimacy between policemen and citizens, the excellence of patrol devices, the speed of response, and the appropriacy of patrol method are grouped as the independent variables. And the dependent variable is the effectiveness of police motorcycle patrol. The results of this study demonstrates that the effectiveness of police motorcycle patrol is affected statistically by the speed of response, the appropriacy of patrol, and the intimacy between policemen and citizens. But, the intimacy between policemen and citizens affected the effectiveness negatively. Therefore, police department must make the effort for increasing the speed of response and enhancing the appropriacy of patrol. Also, police department must make patrolmen sincerely conscious of the value of police-community relation.

This study was carried out to investigate the current state of occupational health management and characteristics of employees working in small-scale-enterprises (SSE) employing less than 50 workers. Samples were chosen among the two thousands employees working in 838 factories where located in Youngdungpo-Ku, Seoul, Korea. The study results were as followed: 1. Most factories investigated in the study were manufactures (68.6%) which were established in 5 to 10 years ago (29.2%), employing less than 5 workers (72.9%) and registered in accident compensation insurance (23.0%). 2. Health screening was undertaken in 24.9% workplaces for periodic health examination and in 1.5% for special health examination. Environmental monitoring was done in 3.3% factories. Very few factories displayed Material Substance Data Sheet (MSDS) in 3.1% among the total factories. 3. Workplaces usually had their own toilets in 75.9% and washing basin in 58.6% as types of sociowelfare facilities. 4. Employees responded in the study were mostly in the range of age from 30 to 39 in 34.7%. male in 84.8%. the married in 70.3%. manual workers in 42.0%. mostly working regularly 51 hours per a week in 48.2% and earned 710.000 Won to 1.000.000 Won per month in 35.0%. Medical utilization for employees were covered by factories sponsored medical insurance in 12.7% and by provincial sponsored medical insurance in 83.4%. 5. Two point six percents of employees were suffered by diseases. The health complaints indicated were mainly digestive problems in 46.7% and hypertension in 24.4%. 6. Employees wore personal protective equipments for work such as gloves in 48.1%. safety shoes in 30.5%. ear plug in 5.5% and mask in 6.9%. Based on the results of study, we recommend that various types of occupational health management should be developed according to workplace working condition of each factory. In addition to the development of occupational health strategies. we think that it is more important to monitor and to allocate how effectively they operate each other on the basis of longitudinal continuity. Besides, we would like to insist that these all management effort should be focused on prevention of disease and occupational health education of employees.

The importance of marine pollution prevention is increasing day by day both at home and overseas. Against this context, this study proposes policy directions to forge an improved system of coastal control for local governments. I have analyzed the coastal pollution response capacity of local governments to find out how the central government can better support these efforts to reinforce capacity. For the purposes of this research, I carried out a number of case studies on large-scale marine pollution accidents that occurred at home and abroad. According to the results, I identified the implications of the coastal pollution response capacity of local governments and suggested several alternatives such as construction of step by step response system, strengthening education and training, part of human network activation, establishment of grounds for securing response resources, and establishment of dedicated department to prepare for potential future marine pollution accidents. However, as little research has been done on the coastal pollution response capacity of local governments, this work may be regarded as an experimental study to help facilitate follow-up research in the future.

In this study, the authors analyzed the limit of IOPC Fund system, such as limit of compensation, amount of FC, long period of assessment by IOPC Fund, issue of non verification by poor claimant or small business, issue of poor claimant subsistence in early stage of accidents, and comparatively analyzed how the three countries resolved these limits by enacting special laws and government policy. Until recently most governments have carried out prevention policy for maritime safety, oil spill response, investigation of maritime accidents, and restoration of marine environment when oil spill accidents happened. However, governments have not actively participated in the oil spill compensation process because it is a matter of private sectors between the polluter and claimant. The governments have only limited their role in ratifying Civil Liability Convention and Fund Convention and enacted relevant domestic laws. However, the governments of France, Spain, and Korea have actively participated in the compensation process of oil pollution incidents of M/T Erika, M/T Prestige, and M/T Hebei Spirit. This is because they had experiences of unsuccessful compensation in M/T Amoco Cadiz, M/T Agean Sea, and M/T Sea Prince.

In this paper, effects on industrial accident prevention based on better safety and health environment by utilizing ergonomics expert were studied. This study was mainly based on the data from 'the survey for occupational safety and health trend' conducted by Occupational Safety and Health Research Institute. The number of industries participated in the survey was 2,084. Main results of the study were as follows; 1) Only 22.9% of the industries participated in the survey utilized ergonomics expert. The rest of the industries have never had an ergonomics expert due to the reasons such as lack of knowledge for the field of ergonomics, etc. 2) Specific activities done by the industries with ergonomics expert in order to have better safety & health were 'providing work orders'(94.8%), 'providing monitoring guidelines'(85.5%), 'providing information for dangerous work'(95.8%), 'providing safety education'(96.6%), and 'other safety management'(94.1%). 3) When the odds ratio for the levels of communication and the levels of environmental stability regarding safety & health for the different groups(with experts and without experts), it was found that the group with ergonomics experts had a significant higher ORs(2.391, 95% confidence interval(1.949-2.932) and 2.128, 95% confidence interval(1.786-2.537)) respectively than those of the industries without ergonomics expert. The results suggested that ergonomics expert has been unique in most of time in terms of his/her contributions in the field of industrial safety and health.
