In South Korea, a certain number of temporary housings are pre-produced and stored in a warehouse, which are later relocated and installed in the areas damaged by disasters. Through the supply of temporary housings upon the occurrence of a disaster, disaster victims are able to rapidly go back to their everyday lives, and the social confusion formed after the occurrence of a disaster is reduced. Although temporary housings can be used for various purposes, they are currently being used only for helping disaster victims and are thus facing the difficulty of continuing technology development due to their low marketability. To increase the use of temporary housings, this study was conducted to formulate a plan for the recycled use of temporary housings in non-disaster situations. This study intended to open wide the possibility of operating temporary housings regardless of the type, period, and scale of the disaster, and to propose a plan for the reuse of temporary housings in non-disaster situations.

현재 도시재생은 대부분 영구적이고 고정적인 계획방식으로 진행되고 있으며, 종합계획 특성상 주민들의 의견을 즉각적으로 수용하기에는 한계가 있다. 본 연구에서는 일시적 활용의 전략을 기반으로 유휴공간의 활용요소를 도출하여 주민 인식조사 및 선호도 조사와 전문가 중요도 분석을 비교하여 일시적 활용 기법을 적용한 유휴공간 활용의 방향성을 제시하였다. 분석 결과, 거주민은 대상지 특성상 노후화된 물리적 환경을 먼저 개선하는 것을 선호하는 반면, 전문가는 빠르게 도시의 환경을 개선시킬 수 있는 일시적 활용의 특성을 담고 있는 활용방안을 중요도에 반영하여 그 순위의 차이가 있었다. 따라서 일시적 활용 전략의 중요성을 인식하고 두 집단의 우선순위 차이를 세분화하여 한시적으로 테스트(Test)를 진행함으로써 최적의 활용방안을 도출하여 종합계획에 반영하는 것이 바람직하다. 향후 일시적 활용 전략을 시행하고자 할 때 대상지 특성과 이용 패턴 분석을 통해 면밀한 사전조사와 이를 반영한 공간 활용 계획이 제시되어야 할 것이다.

The use of temporary Gondola has been steadily increasing. The temporary Gondola is required to get a safety certification review during installation and to be inspected during use within every six months. Most of them, however, are dismantled before six months, and inappropriate activities are conducted frequently for shorter working hours and convenience of work. In this study, the characteristics of the temporary Gondola and the domestic accident cases that occurred over the past 10 years(2008-2017) are analyzed for the type of accident, the state of the accident by year, and the actions of the workers in the event of an accident. Also comprehensive accident reduction measures were proposed by identifying the fundamental causes of temporary Gondola accidents, problems of existing preventive measures, and system defects by utilizing Bow-Tie techniques.

The Temporary construction refers to the construction or dismantling of temporary structures installed for the construction of the main structure at the construction site, and the members constituting this temporary facility are called temporary equipment. Temporary equipment used in construction sites is mostly used products that are reused rather than new products, and it is necessary to consider performance degradation due to repeated use. This study is a preliminary study to develop the performance evaluation criteria applied to temporary equipment that is distributed and reused for secondhand. This study is to analyze the performance status of temporary equipment of used goods owned by rental companies by condition grade through performance tests.

With the development of wireless networks and the use of mobile devices, mobile user's privacy issue is becoming more and more important. Privacy includes ID anonymity and unlinkability. Unlinkability requires that any two temporary IDs which have been used before should not be associated with each other. In other words, these temporary IDs should be generated in such a way that no direct relationship among them should be derived. The existing schemes only focus on ID anonymity of mobile users. In this paper, we proposed a scheme not only holding all the merits of previous works, but also achieving unlinkability which is guaranteed by using one-time-use temporary ID. And the mobile user can also updates its one-time-use temporary ID with the help of the visited foreign agent.

Concrete construction requires utilization of many temporary facilities such as formwork, shoring, and scaffolding. Appropriate use of these temporary facilities greatly impacts the quality, cost, schedule, and safety of concrete construction. The current practice in design and planning of temporary facilities is often manual, error-prone, and re-active based on construction site layout, status, and progress in the field. Early design and planning of temporary facilities for concrete construction using Building Information Modeling (BIM) technology offers a potential solution. Although some commercially-available software exists that assists in the generation of temporary facility designs, the construction industry lacks tools that support detailed planning and design of many other temporary facilities. This research presents our early work in automating the design and planning of temporary facilities utilizing BIM. Algorithms were developed to automatically assess geometric conditions of work space to detect required temporary facilities and design them. The proposed methodology was implemented in a test model. By automatically incorporating temporary facilities into BIM, more realistic construction models can be created with less effort and errors. Temporary facilities-loaded models can finally be used for communication, bill of materials, scheduling, etc. and as a benchmark for field installation of temporary formwork, shoring, and scaffolding systems.

Background Although the use of temporary shunts in proximal extremity amputations has been reported, no study has described the use of temporary shunts in distal extremity amputations that require vein grafting. Moreover, the total volume of blood loss when temporary shunts are used has not been reported. The aim of this study was to investigate the applicability of a temporary shunt for distal extremity amputations requiring repair by vessel grafting with an ischemia time of >6 hours. This study also aimed to determine the total volume of blood loss when temporary shunts were used. Methods Patients who underwent distal major extremity replantation and/or revascularization with a vessel graft and who experienced ischemia for 6-8 hours between 2013 and 2014 were included in the study. A 6-Fr suction catheter was cut to 5 cm in length after the infusion of heparin, and secured with a 5-0 silk suture between the distal and the proximal ends of the artery. While bleeding continued, the bones were shortened and fixed. After the complete restoration of circulation, the arterial shunt created using the catheter was also repaired with a vein graft. Results Six patients were included in this study. The mean duration of ischemia was 7.25 hours. The mean duration of suction catheter use during limb revascularization was 7 minutes. The mean transfusion volume was 7.5 units. No losses of the extremity were observed. Conclusions This procedure should be considered in distal extremity amputations requiring repair by vessel grafting during critical ischemia.

Purpose : When natural disaster occurs, the victims are evacuated to temporary shelters such as indoor gymnasiums or large space buildings until their homes are recovered. If someone in this temporary shelter is infected with an airborne infectious disease, it becomes easier for the disease to spread to the other people in the shelter than it would be under normal conditions. Therefore, temporary shelters need to provide not only water and food but also hygienic indoor conditions. Methods : In this study, the use of mechanical systems such as ultraviolet germicidal irradiation (UVGI) systems and air cleaners were simulated using numerical analysis to find out how these systems can control airborne infection in temporary shelters. An indoor gymnasium was selected as a temporary shelter for the numerical simulation model considering Korea's post-disaster response system. Influenza A virus was assumed as an airborne infectious disease and the diffusion of the virus was made by one person in the shelter. Results : The result of this study showed that the UVGI systems disinfected the virus more effectively than the air cleaners by creating a more stable airflow after the disinfection process. The air cleaners could remove the virus but since it created an unstable airflow in the temporary shelter, the virus was condensed to a certain area to show a higher virus concentration level than the source location. Implications : In the temporary shelter, it is necessary to use UVGI systems or air cleaners for hygienic indoor conditions.

The use of temporary container classrooms has increased in recent years due to the development of the construction industry and renovation or rehabilitation of schools. Therefore, various problems, such as errors during assembling, design and insulation issues, and noise problems, have surfaced during the construction of temporary container classrooms. This study analyzes the causes of assembly errors during the manufacturing and installation processes to improve the quality of temporary container classrooms. Assembly errors are caused by non-level planes and inaccurate cutting during the manufacturing process. In the installation process, poor leveling is a major factor that causes errors during the assembly of temporary container classrooms. These causes result in uneven horizontal or vertical planes and uneven height. To solve these problems, quality improvement measures, such as pin connection, jig, joint coupling, and surface plates are proposed in this study.
