  • In the case that high-rise building is constructed, the surrounding wind velocity increase more than 50~100%. From this cause, many wind environmental problems can be occurred. For example, ordinary wind environmental disaster may be occurred in a region, or walking disturbed. In developed countries including USA, EU, and Japan, many efforts have been made for building wind prevention by grasping previously the effects before building constructed. But, We are bearing risk of wind environmental disaster because we have not enough recognition about building wind, and have not architectural prevention counterplans. This study aims to examine wind environmental characteristics of domestic apartment complex, and effective architectural counterplans. As the basic stage for this, we investigated pre-estimate tools and risk assessment methods of building wind in apartment complex, applied to two apart complex in Cheon-An region by CFD. As the result, serious damages were not presented. But, it is obvious that various architectural counterplans will be presented by this example researches.

  • Annually, many parts of the Korea have been damaged from the localized heavy rain and/or typhoons which peak between June and September, which result in extensive financial and human loss. Especially, because the most area of Gangwon province is composed of the steep slope mountains, the damages by the debris flow or land-sliding are more frequent and the frequency has been increased. To analyze the characteristics and causes of these debris flow disasters, lots of study are recently being conducted through database of weather, hydrologic, soil etc using a GIS or remote sensing. In this study, we applied GIS method to analyze the risk of the debris flow area. With the statistical analysis and infinite slope stability model(SINMAP), the debris flow risk level of the mountain slope was generated. As a result, the GIS statistical analysis showed high correlation that former model of SINMAP in determining the debris flow risk area.

  • Construction sites have various risks, and safety managements are enforced based on the law such as Industrial Safety and Health Act, etc. Safety management by the law saves lives and preserves health of workers by removing and understanding risks in advance. When the emergency situation has come, poor response causes loss of lives and physical damages. This study suggests basic strategy that can mitigate the industrial disaster in all construction sites. A survey was conducted to identify the current safety consciousness and to evaluate first aid ability of coworkers. Finally, four measures were suggested: (1) designating muster points; (2) hiring occupational health managers; (3) increasing the first aid ability of coworkers; and (4) carrying safety brochure. The proposed suggestions can be helpful in mitigating the construction disaster, and in responding the major accident efficiently within a short time.

  • A debris flow is known as that flood and landslide of water cause much physical human damages worldwide to complex natural disaster that happen combining and happy event is happening mainly in urgent mountains area in domestic. Because happen about debris flow that happen from each place every year and is drift, mechanism of accumulation definitely make clear and great many damage is not running out. Must grasp actual conditions of priority debris flow to need debris flow prevention countermeasure and lay countermeasure to take away damage by debris flow. Because collecting actual conditions of debris flow that happen by objective investigation methods and accuracy, proposed about investigation calamity investigation method so that can calculate debris flow damage and prepare in subsequentness damage.

  • The aim of these studies is to confirm the red and blue painting damages during the fire suppression of wooden cultural assets by using the loaded stream charge extinguishant. As a results of these experiments, the ingredients of extinguishant existing on the surface of wooden cultural assets were perfectly eliminated by the water washing only. Any changes on the surface of wooden cultural assets couldn't be detected. Moreover, any color changes of the red and blue painting didn't occur.

  • The amount of damages caused by natural hazards is consistently growing due to the unusual weather and extreme events. At the same time, property damage by natural hazards is rapidly increasing as well. Hence, we need systematic anti-disaster activities and consulting that can react to such a situation. To address these needs, we investigated and analyzed insured claim payouts from natural hazards by administrative area, and calculate the risk index utilizing GIS. According to the index, this map is identifying the areas of greatest natural hazard risk. The ranking of natural disaster vulnerability based on the risk index, and risk grades were divided into five based on the ranking. This map integrates the natural hazard losses to assist in comprehensive and effective loss prevention activities using analysis of regional loss claims from natural hazards. Moreover, this map can be as utilized as loss mitigation and prevention activities to verify the distribution of exposure and hazards.

  • In this paper, warm asphalt binder was proposed as a substitute for the polymer-modified asphalt binder to get higher viscosity than that of the polymer-modified at the same temperature. Performance grade test and rotational viscosity of warm asphalt binder were conducted to evaluate the property variations due to the addition of admixture. Research results showed that the viscosity of warm asphalt binder at $100^{\circ}C$ was similar to that of the conventional asphalt binder. The performance and durability of warm asphalt binder were also comparable to those of the polymer-modified. It is considered that the active applications of warm asphalt binder can reduce environmental damages due to less diffusions of carbon dioxide compared to the conventional.

  • This paper presents the field applications of polymer-modified warm asphalt mixture which can reduce the temperature during the production and field constructions. The amount of fuel consumptions and $CO_2$ diffusions can be reduced by much using the polymer-modified warm asphalt mixture instead of the conventional polymer-modified asphalt mixture. According to the research results, the polymer-modified warm asphalt mixture can be utilized without additional temperature increasement and performance sacrifice during the plant production and public service, respectively. As a result, it is considered that the application of the polymer-modified warm asphalt mixture has the potential of convenience in constructions management and reducing the environmental damages.

  • Asphalt concrete pavements are often destroyed within the intended design life due to the increasement in traffic volume. The most common types of asphalt concrete pavement damages are permanent deformation and fatigue cracking, and so on. In this research, characteristics of traffic loadings and lateral wheel path distributions are analyzed using the field survey on traffic flow. The obtained traffic characteristics can be used to the decision making for the maintenance policy of roads. According to the traffic lane analysis for the 2nd and 3rd lanes, inner lane vehicles tended to pass to the right side to avoid the opposite side vehicles. In addition, the outside lane vehicles were deviated to the left side to avoid passengers. It is also noted that the lateral wheel path distributions was close to the normal distribution.
