Purpose: This study has developed economical and environmentally friendly storage type infiltration facilities that securing storage space inside the infiltration facility. It focused on preventing flooding rainfall as well as securing more groundwater through rainwater infiltration that is valuable for the dry season. In addition, this study compares the installation cost of the storage-type infiltration facility to the cost of the conventional rainwater management facilities to demonstrate the economic efficiency of the storage-based infiltration facility. Method: Unit infiltration of this facility is calculated and when it was applied to a certain capacity, the amount of countermeasures are proposed in case study. Result: Unit infiltration of it is $0.2541m^3/hr$ and un it Temporary storage of it is $1.054m^3/m$. As a result, the infiltration effect of this facility is $1.306m^3/hr$. The cost was approximately 30% reduction in time to apply the storage type infiltration facility as compared with the case to apply the existing penetration of the facilities. Since the penetration of the existing facilities is smaller than that and it has much securing volume to process the same the amount of countermeasures. Therefore, it is determined that the cost significantly increases in material cost part. On the other hand, storage type infiltration facility is installed a small quantity because Unit Temporary storage and infiltration are bigger than that. So, it occurred to reduce material and installation costs.

The study aims to identify the existing problems and suggests the implication for the planning of emergency shelter in terms of users' habitability. The results of the study show that the concept of shelters for disaster victims need to set up and be distinctively defined as emergency phase and temporary residency phase. In emergency phase, the various types of buildings and facilities should be considered as temporary shelters for disaster victims such as transitional shelters including the public facilities. Based on the results of the critical review, this research proposed an analytic framework emphasizing habitability for disaster victims including vulnerable people such as the disabled, the aged, women and children. The framework is composed of four dimensions: safety, health, convenience and comfortability. The manual guidelines for emergency shelters should reflect the barrier-free design or universal design for various types of disaster victims considering habitability to provide the positive opportunity and future hope for restoration after disaster. This research can be a basis for the planning and application of temporary shelters for disaster victims.

The purpose of this study is to analyse the characteristics of Korean railway architectural facilities constructed during the Japanese ruling period through an examination on the historical documents. The findings of this study are as follows: Firstly, the Japanese railway adminstration authority in Korea defined the criterion for each architectural facilities according to the climate zone. Secondly, these criterion were object to modification by the geo-political. changes and the augmentation of demands. Thirdly, each architectural facilities had been remodeled or expanded, from a temporary building type to a more permanent type, consequently by the development of the Korean railway network.

During excavation works for underground facilities, temporary tieback wall with earth anchor system was investigated for safety's sake. An excavation 9.7 meter deep was monitored by slope inclinometer in twelve measuring points. Instrumented lateral displacements of the wall during 177 days are represented. Especially, lateral displacements of the two positions under completely different condition are compared to investigate the effect of backfilling between soldier pile and the soil behind wall. The deformation behaviors of the wall according to both depth and elasped time are discussed. Finally, a numerical analysis by the program FLAC was performed, and calculated displacements are compared to measured ones.

Recently, natural disasters have unexpectedly occurred at various places in the world and the countermeasure of them become the social issues. Many of victims in disasters need temporary residential facilities above all things and many of researches have been conducted in order to develop simple, safe, and economic designs of them. Moreover, indoor thermal comfort and air quality must be considered in the facilities against a disaster, because clean and healthy space should be provided to the suffered victims. In this research, in order to estimate the indoor environment of the developed modular building for disaster preparation, CFD simulation was conducted in the various condition. In this paper, indoor air quality such as the age of air, the concentration of $CO_2$ was estimated by the case study

Determining the layout of temporary facilities that support construction activities at a site is an important planning activity, as layout can significantly affect cost, quality of work, safety, and other aspects of the project. The construction site layout problem involves difficult combinatorial optimization. Recently, various artificial intelligence(AI)-based algorithms have been applied to solving many complex optimization problems, including neural networks(NN), genetic algorithms(GA), and swarm intelligence(SI) which relates to the collective behavior of social systems such as honey bees and birds. This study proposes a site facility layout optimization algorithm based on self-organizing maps(SOM). Computational experiments are carried out to justify the efficiency of the proposed method and compare it with particle swarm optimization(PSO). The results show that the proposed algorithm can be efficiently employed to solve the problem of site layout.

The key role in safety management is to identify any possible hazard before it occurs by identifying any possible risk factors which are critical to risk assessment. This planning/assessment process is considered to be tedious and requires a lot of attention due to the following reasons: firstly, falsework (temporary structures) in construction projects is fundamentally important. However, the installation and dismantling of those facilities are one of the high risk activities in the job sites. Secondly, temporary facilities are generally not clearly delineated on the building drawings. It is our strong belief that safety tools have to be simple and convenient enough for the jobsite people to manage them easily and be flexible for any occasions to be occurred at various degrees. In order to develop the safety assessment system, this research utilizes the BIM technology and collects important information by importing data from BIM models and use it in the planning stage.

The object of this study is the safety insurance of the dam to provide for the extraordinary flood. The safety insurance of the reservoir was taken by the preparatory discharge using the temporary division tunnel used during the reservoir construction. In this study, the Sungju reservoir was simulated. The existing discharge facilities of the intake tower of the Sungju reservoir could nat have influence on the flood control. When the Sungju reservoir operated to begin preparatory discharge for 48 hrs by the temporary diversion tunnel that have discharge of an 20-years frequency, the water level was lowered about 20 cm. When the Sungju reservoir operated to begin the continuous discharge after the preparatory discharge, the water level was lowered over 1m but the downstream at risk was caused by the resulted. If it is possible to operate to begin the preparatory discharge of the reservoir for 24 hrs by the temporary diversion tunnel, that will improve the flood control faculty of the reservoir without other hydraulic structure and safety of the Sungju reservoir will be higher.
