This paper presents the design of attachments for dual arms of disaster responding heavy machine. The heavy machine handles a variety of tasks such as cutting, shredding, picking and moving in unstructured environment. Despite the need for rapid response, the heavy machine has difficulty in repeatedly replacing the attachment depending on the task. Thus, we propose a method to solve this physical and functional contradiction relation by using TRIZ separation principles. Above all, the existing equipment and the required working scenarios were surveyed and summarized in order to separate the attachments functionally for right-handed, left-handed and two-handed operation. Then, we proposed the design directions and conceptual design as following: multi function type attachment A, for precise operation and various operations; grab type attachment B, for grasping irregular objects and auxiliary device for both arms to handle bulky objects.

We are concerned with the dual-arm manipulation for disaster-responding special-purpose machinery. This paper presents a control strategy for performing complex work in an irregular environment, the control algorithm, the hydraulic circuit, and the master devices. The occurrence of collapse accidents at disaster sites such as natural disasters and building collapses is increasing, which is emerging as a social problem. In particular, for the initial response, various tasks must be performed in an irregular environment. The Marionette algorithm for intuitive control of 'as if the operator's arm is moving' was presented as a control strategy for dual-arm manipulators with attachments and the prototype. Next, the hydraulic circuit, control system, and wearable-type master device presented to implement the Marionette algorithm were explained and verified through an experiment in which rebar-cutting, drum-lifting, and lifting a bottle with one arm and pouring the water into the bucket with the other arm were tested.

This paper introduces the results of analysis of questionnaries for developing the effective responding method against social disasters by using ICT technologies. Over 200 peoples including 146 citizens and 55 officials and fireman responded on the questionnaries. In analytical results, approximately 87% citizens answered that the current disaster responding system has some problems, and also over 82% citizens is expecting that ICT is available to reduce the social disaster. For the question of necessity and efficiency of ICT implementation, many officials answered that the information of GIS and facilities would be mostly useful information to respond the social disaster.

The need for the development of practical manuals for responding to disasters in public libraries has emerged after COVID-19 was confirmed in Korea in January 2020. The library is a social organization directed affected by COVID-19. Therefore, a reasonable and consistent disaster response manual should be developed and used as a guideline for responding to disasters at the library sites. This study aims to derive implications by examining the current situation of public library manuals for both domestic and international. Furthermore, the responses of overseas libraries experiencing major disasters were analyzed and issued to reflect the current domestic situation. As a result of the study, it was suggested that the library's role as a social organization for disaster response should be enhanced, and that disaster experience needs to be implemented, as guidelines, toolkits, and archive.

Caused by the Cheonanham attack and the Yeonpyeongdo bombardment occurred a few years ago, and the recent North Korea's nuclear test, the war crisis between South and North Korea has been increasing. Accordingly, an interest in obtaining a temporary residential space, for the case of the outbreak of war, where people can reside safely over a period of time has been escalating. However, in the disaster relief planning guidelines of the National Emergency Management Agency, the standards on the temporary residential spaces in preparation for storm and flood or earthquake are included, but the standards on the ones in responding to war are not yet equipped. In particular, the standards on the underground temporary residential spaces that can accommodate massive victims should be developed in preparation. In this study, through a requirements analysis based on the survey of war victims and a comparative analysis between disaster-related laws and regulations, the direction of relevant system improvement for the utilization of temporary residential spaces in responding to war is established.

Korea, old buildings do not currently have earth-resistant facilities, and disaster prevention facilities have some limitation in responding properly to damage arising from natural disaster as they do not reflect recently occurring climatic changes. Accordingly, it is necessary to select vulnerable districts by taking into consideration the possibility of disaster occurrence and the current situation of infrastructures for disaster prevention in order to responding efficiently to future unexpected disasters. For this purpose, national government has recently formed the DB linkage council for disaster prevention under the participation of related agencies and constructed integrated database. But local governments have not properly provided it with basic data necessary to construct database, resulting in the delay of the project. Therefore, it is thought that national government needs to provide them with manpower and financial support.

Recently, localized heavy rain is increased by climatic changes and landslide is increased. Also, because of landslide occurred in urban area, life and property damages are increased. Therefore, standard operation procedure of disasters should be established by steps and institutions so as to respond landslide. This thesis investigated application of current disaster manual so as to write SOP of landslide for disaster prevention related experts and accepted opinion for responding necessaries by using landslide SOP and important matters by step of disaster management. As the result of investigation, application of manual was low during the current response to disasters and application was the highest in responding step among the steps of disaster management. In case of landslide, they responded that response with SOP is necessary. During the organization of landslide SOP, they responded that training and education for landslide disaster are important at the step of prevention, conduction of landslide disaster broadcasting and provision of information are important at the step of preparation, guidance for evasion and behavior methods is important at the step of response and investigation of landslide disaster damages and reflection of record and evaluation are important at the step of recovery. In addition, for the requests for landslide SOP application, there was an importance of secondary factors such as expansion of professional manpower, strengthening of law and institution, education and training for SOP acquisition, etc.

Recently, the COVID-19 Pandemic is not an infectious disease-level disaster, but a complex disaster, making it difficult to respond with traditional disaster response management methods. As a result, experiencing psychological stress and trauma such as COVID-19 has emerged as a new social problem. In preemptively predicting and effectively responding to these psychological disasters and crises, the necessity and direction of non-face-to-face disaster psychological support using ICT technology in traditional services are discussed.

On 11 March 2011, earthquake occurred in Japan were left with the significant human and material damage. Among these, social media has emerged as a very useful communication channel by playing a important roles in the process of safety checking and disaster recovery. In fact, however, we have no specific response methods or systems to these occurrence of disaster in Korea. Therefore, we investigate the relevant literature in order to analyze the current status of foreign and domestic utilization of social media, and draw the ideal ways to use social media for responding to unpredictable disasters based on the relevant literature reviews. The results of this study are summarized as follows. First, Institutions such as Meteorological Administration or National Emergency Management Agency are able to utilize social media as the communication systems to public in emergency. Second, social media are able to used for building disaster information systems including location information such as emergency call for help or requests for dissemination materials. Lastly, online donation services via Facebook or Twitter are able to be provided. The findings have significant implications for official responsible for disaster response and academic researchers.
