This technology is to let rainwater flow into a waterway that is located side gutter of a street with blocking garbage including cigarette butts at the same time. The first waterway is located beside the sidewalk and it enhances the water circulation in a city. This waterway is filled with aggregates and filter media, which removes fine dust that is washed out of the street and let water flow down to the earth. The second waterway is located beside the street and it retains rainwater temporarily with decreasing its flow speed. The second waterway shall reduce flooding damages by avoiding bottleneck situation in the street inlets and storm water pipelines which is the main causation of flooding in a city.

Korea Government promotes the installation of buffering retention facility to protect the water environment and prevent the environmental contamination event by toxic materials. Although the buffering retention facility is very important to protect the natural environment through the retention of accidental pollution and initial runoff, much study has not been done to suggest the guide line for the design of the facility. In this study, we suggested the rational items for the design of buffering retention facility based on many experts after we investigated and compared the previous results of many design materials.

In this study, the amount of debris flow was calculated through the empirical equations of RUSLE, NILIM, and Marchi, which are widely used to calculate areas affected by debris flow, and debris flow measured through precise measurements and field surveys was compared. The RUSLE method over estimated by 2.13 times in the average sense compared with the measured sediment quantify and Marchi's empirical equation over estimated by 2.83 times while NILIM's empirical equation 1.26 times, which is the lowest error among the three empirical equation.

Hate crimes should be viewed as a social problem, not a personal crime, and a preventive system should be established to have an acceptance system for people who can engage in antisocial behavior outside of the social integrated value norms. In particular, in order to reduce tragic hate crimes, society and the government should actively work to resolve polarization, and personality education linked to families, schools, and society should be provided, and policies to establish social safety network such as social security systems should be prepared. In addition, it is necessary to switch to a society in which principles are emphasized, and a society that cares for the weak rather than the strong, rather than the expedient policy of words.

After the 10.29 Itaewon disaster, interests in the crowd crush injury increased, but it is pointed out that the academic and practical basis related to crowd crush is still weak in Korea. Therefore, in this study, terms and concepts related to crowd crush were investigated and proposed, and representative cases of crowd crush events were investigated and summarized. Approaches based on representative cases were investigated, and among them, video analysis, simulation, questionnaire survey and interview methods were derived as an essential approach methods. Through this research, it is expected that standardization of Korean terminology, concept establishment, evaluation, and systematization of approach methods of crowd crush can be accomplished.

This study conducted an empirical analysis based on the results of a survey conducted to determine the level of awareness of disaster safety management work of public officials working in disaster-related departments in 22 cities and counties in Jeollanam-do. Men were found to have more positive perceptions of individual competencies and organizational environments according to gender, and women were found to have more positive perceptions of disaster education than men. It was found that men and women had the same positive perception of departmental competency. Respondents to individual competency, organizational environment, departmental competency, and disaster education according to individual characteristic factors generally had positive perceptions.

According to the disaster statistics issued by the Ministry of Public Safety and Security, traffic accidents, fire, collapses and others are classified into twenty-three (23) categories. In the past, disasters were mainly caused by the influence of nature, such as typhoon or drought. On the other hand, as society has become city-centered, social disasters' types, frequencies and scales are becoming more diversified and ever-increasing. However, there are no specific criteria and assessment methods that can measure degrees of social disasters-related risks objectively. Therefore, this study targeted traffic accidents, fire and collapses from major social disasters, utilized data that are related to occurrence rate, scale of casualties and scale of property loss in past eight years, and calculated the disaster risk index using the distance (Euclidean distance) between two points on the 3D spatial coordinates, in order to make the objective assessment by social disaster type possible. These results will enable the objective evaluation of risk index of major social disaster to be used as the foundational data when building the national disaster management system.

Notwithstanding industrial accident decrease generally, Construction industry is on the rise recently. Most accident occurs in the small scale like as multiflex housing, remodeling, neighbourhood facility more than safety supervisor appointed large scale construction site. By the size of business place, 81.6% of total accident occurs mostly in small scale site that is bellow 120 billion won and 50 manpower. This paper aimed that small scale housing company achieve a zero hazard practising and understanding the safety adminstration standar d model easily and it applied firstly after investigating the operation condition of construction site safety control in small scale company propelling the complex style multiflex housing business.

The recent earthquakes in the peninsula've called safe areas prone to earthquakes occurred the unprecedented human and material damage. It does not have the seismic design of buildings for less than three layers, with the exception of some experts and organizations, and it does not have to read about the seriousness and evacuation tips for earthquake damage is thought to have been weighted. As mentioned above, most people are unaware of the evacuation tips or saengjonbeop, emergency supplies, such as earthquakes compared to a situation without the various needs education. So we were prepared for an earthquake is now managing investigate the cause and correct entities for the earthquake is considered as the time to prepare and formulate a policy. In this study, we investigated the cause to frequent earthquakes with respect to the Korean Peninsula and to organize for our government and local governments, NGOs, the media and individuals on how to proceed.

Domestic harbor yard storage facilities are a place specifically located in a container terminal for import and export of packaged dangerous goods, and due to the recent relaxed criteria for the secured open area, concerns for the extended damage upon accidents are increasing. In this study, the impact of damages by radiant heat was analyzed through a simulation of a pool fire caused by the leakage of flammable liquids from a tank container. As a result, it was analyzed that the distance of radiant heat according to threshold damage levels was beyond the current criteria of the secured open area, and the structural damage of adjacent containers could happen within a very short time if they were exposed to the early pool fire continuously. It is considered that this study will be helpful in preparing the proper criteria for the secured open area between yard storage facilities in a container terminal.
