This study aims to create a disaster management system after an earthquake. Japan's earthquake disaster management system, including the Disaster Countermeasures Basic Act, addresses all of the disaster phases of prevention, mitigation, preparedness and emergency response as well as recovery and reconstruction with roles and responsibilities among the national and local governments clearly defined. Korea's earthquake disaster management system are including the Disaster Countermeasures Basic, but when the 9.12 earthquake occurred, problems such as insufficient early response, study on the earthquake lack were revealed. This study conducted a field survey and analyzed coping process after Po Hang earthquake. Therefore, this study have found that Disaster Management Headquarters are operated rapidly. They are coped with urgent safety inspection for damage facilities and soil liquefaction with advanced equipment. And The headquarters interviewed with victims. So they found out What the victims needed. However, when carrying out relief activities, Research of temporary housing and allocation of donations was not rapid. Further, this study have found that earthquake specialists were lack and disaster information transfer was not working. This study will be utilized as fundamental data in planning disaster management system after an earthquake.

Strong earthquakes have caused substantial losses in recent years, and earthquake risk prevention has aroused a significant amount of attention. Earthquake risk prevention products can help improve the self and mutual-rescue abilities of people, and can create convenient conditions for earthquake relief and reconstruction work. At present, it is difficult for earthquake risk prevention information systems to meet the information requirements of multiple scenarios, as they are highly specialized. Aiming at mitigating this shortcoming, this study investigates and analyzes four user roles (government users, public users, social force users, insurance market users), and summarizes their requirements for earthquake risk prevention products in the whole disaster chain, which comprises three scenarios (pre-quake preparedness, in-quake warning, and post-quake relief). A targeted recommendation rule base is then constructed based on the case analysis method. Considering the user's location, the earthquake magnitude, and the time that has passed since the earthquake occurred, a targeted recommendation model is built. Finally, an Android APP is implemented to realize the developed model. The APP can recommend multi-form earthquake risk prevention products to users according to their requirements under the three scenarios. Taking the 2019 Lushan earthquake as an example, the APP exhibits that the model can transfer real-time information to everyone to reduce the damage caused by an earthquake.

Performance-based design concepts require the next generation of codes. To implement the main concepts several design methodologies have been proposed. This paper reviews the framework of Korea Seismic Code and shows necessary modification for adoption of appropriate design methods. The selection of design earthquake levels with the introduction of risk factor is discussed for proper risk levels for all earthquake hazards. Displacement-based design, energy-based design, comprehensive design, and force-strength design methods are reviewed as one of possible next generation design methods. This paper proposes the direction of reconstruction for design earthquake levels with performance matrix, introduction of new design methods, and emphasis on non- structural components.

This paper presents the development of Artificial Neural Network models for forecasting the cost and contract duration of school reconstruction projects to assist the planners' decision-making in the early stage of the projects. 132 schools reconstruction projects in central Taiwan, which received the most serious damage from the Chi-Chi Earthquake, were collected. The developed Artificial Neural Network prediction models demonstrate good prediction abilities with average error rates under 10% for school reconstruction projects. The analytical results indicate that the Artificial Neural Network model with back-propagation learning is a feasible method to produce accurate prediction results to assist planners' decision-making process.

이 글은 동일본대지진 피해지의 부흥계획 속에서 제기된 공간쟁점을 분석하여, 그 현황과 전망을 제시하는 것을 목적으로 한다. 특히 지진해일 피해를 입은 시가지 재생에 초점을 두고, 지방도시가 지닌 지역개발의 과제가 이번 진재를 통해 어떻게 전개되는지 고찰하였다. 연구지역에서는 고밀도 도시, 어촌의 집약화, 지속가능한 도시 담론이 재해부흥을 위한 이상적인 방안으로 등장하였다. 그러나 현실적 한계로 인해 공간재편은 장벽에 부딪쳤으며, 재건이 늦어지면서 지역에서는 공동화 현상이 심각해지고 있다. 이는 재해 이후 거의 필연적으로 발생하는 지역의 쇠퇴를 방지하기 위해서, 응급 복구뿐 아니라 장기적인 부흥을 시야에 넣고 재해연구의 영역이 확대될 필요가 있음을 시사한다.

The purpose of this study is to investigate the cause of repeated accidents through the investigation and analysis of the collapse cases of domestic earthquakes in order to prevent the earthquake disaster in the urban redevelopment and reconstruction. It is designed and constructed to draw out various problem factors and to find solutions to these problems. And the contents related to various laws and systems of the construction project management stage. Especially. In the management of the construction management centered on the safety management and quality control of the technical aspect design, supervision, construction phase through the cause of the accident and improvement measures based on the investigation report of the collapse of the construction site near Sangdo Kindergarten in Seoul. Supervisor. And constructors should be settled on the responsibility and responsibility of God. In order to achieve the purpose of the project, a system is established to link worker-centered occupational safety and health management with technology-based safety construction management, and analysis of how the quality control of the earthquake prevention affects safety construction management The purpose of this study is to prepare the optimum management plan of construction business.As a result of this study, it is aimed to accomplish the purpose of small scale redevelopment and reconstruction construction project by providing optimization method in the stage of construction project management in order to prevent collapse caused by differences in design,Is expected.

It is very important to allocate valuable resources efficiently when reconstructing buildings after earthquake damage. This paper proposes the use of a simple seismic retrofitting system to make buildings more resilient than the stiffer systems such as the shear walls implemented in Chile after the earthquake in 2010. The proposal is based on the use of steel chevron-type braces in RC buildings as a dual system to improve the seismic performance of multistory buildings. A case study was carried out to compare the proposal with the shear wall solution for the typical seismic Chilean RC building from the structural and economic perspectives. The results show that it is more resilient than other stiffer seismic solutions, such as shear walls, reduces the demand, minimizes seismic damage, gives reliable earthquake protection and facilitates future upgrades and repairs while achieving the level of immediate occupancy without the costs of the shear walls system.

This paper collected 132 schools reconstruction projects in central Taiwan, which received the most serious damage from the Chi-Chi Earthquake. Regression analysis was implemented to build the prediction model of the cost and the duration for the collected projects. It is found that the cubic regression models are capable for predicting the cost and the duration of the projects contracted by the central agency of which the contracting awarding approach was based on the most advantageous tendering (MAT) approach. On the other hand, power regression models are capable for predicting the cost and the duration of the projects contracted through the low bid tendering (LBT) approach. It is also found that the performance of the regression prediction model differs in accordance with organizations that contracted the reconstruction projects.

Damage to earth structures for roads, railways and residential areas, as well as dams and river levees, during the 2004 Niigata-ken Chuetsu earthquake in Japan, and their rehabilitation works are overviewed. Several influential factors are pointed out, such as a) heavy rainfall preceding the earthquake, b) large aftershocks, c) geological conditions for subsoil including existence of liquefiable layers, d) compaction degrees for embankment, and e) drainage capacity from subsoil/embankments. It is also reported that, in the reconstruction works of damaged roads and railways, preferred use of geogrid-reinforced soil retaining walls was implemented.
