The purpose of Serious games in immersive Metaverse platform to provide users both fun and intriguing learning experiences. We proposes a serious game for self-trainable fire evacuation drill with collaboration among avatars synchronized with multiple trainees and optionally with real-time supervising placed at different remote physical locations. The proposed system architecture is composed of wearable motion sensors and a Head Mounted Display to synchronize each user's intended motions to her/his avatar activities in a cyberspace in Metaverse environment. The proposed system provides immersive as well as inexpensive environments for easy-to-use user interface for cyber experience-based fire evacuation training system. The proposed configuration of the user-avatar interface, the collaborative learning environment, and the evaluation system on the VR serious game are expected to be applied to other serious games. The game was implemented only for the predefined fire scenario for buildings, but the platform can extend its configuration for various disaster situations that may happen to the public.

Purpose: The purpose of this study was to investigate the disaster experience (accidents, education etc) and the concern for disaster preparedness of college students. Methods: This research design was a descriptive study. Data were collected from November 1, 2011 to December 30, 2011 and analyzed by the SPSS PASW statistics 18.0 program. Results: There were statistical significances in major (p<.050), grade(p<.001), and a completed disaster class(p<.001) between general characteristics and concern for disaster preparedness. The major disaster events that occurred from 2003 to 2010 in Korea were the 2007 Taean oil spill (85.4%), the 2003 Daegu subway fire (82.7%), and the 2008 Sungnyemun fire (62.9%). The possible disaster events in Korea were hurricanes, floods, fires (including wildfire), and the shutdown of communication lines. Subjects learned about cardiopulmonary resuscitation (18.2%), first aid for bleeding and fractures (17.8%), a fire drill (14.3%), and an escape drill for an earthquake (14.0%). They wanted to learn the fire drill (11.33%), the escape drill for an earthquake (9.7%), a war drill (9.0%), a disaster confrontation drill on the subway (8.6%), and a fire and explosion evacuation drill (8.4%). Half of subjects were not prepared with emergency supplies for disasters because they thought that a disaster would not occur. Conclusion: It is necessary to develop the disaster educational programs according to subject's demands in Korea.

In a daily life these days, the safety and the comfort are considered very important. As the same as other areas, the good maintenance of fire protection systems and the fire drill plans in buildings can minimize the loss of human life and the property in case of fires. In this paper, a survey has been conducted to investigate the maintenance status of the fire protection systems of apartment buildings, shopping center and office buildings. Both practical procedures for checking the systems and for fire drills and strategic plans to minimize the losses in case of fires are suggested by analyzing how well the occupants in the buildings acknowledge the evacuation drills when the fire occurs.

As building height is increased, more careful decisions about the required safe egress time is needed for evacuation. This study analyzed the influence of three training sessions on the vertical speed of evacuation in the high rise building. Evacuation experiments were done in a high-rise office building in Seoul, and we analyzed the vertical evacuation speed as a function of density using a camera. Controlled and uncontrolled total evacuation were compared using the Pathfinder simulation. The process of repeated training, changed the specific stair utilization rate from 6.3% to 39.5%. The vertical evacuation speed as a function of density was analyzed using the equation s = 1.004 ? 0.288D, which is very similar to the equation used in a different study. The total evacuation time of the special controlled total evacuation was reduced by about 25% compared to the simultaneous evacuation.

This study is intended to suggest some ideal measures available in the course of construction from the viewpoint of an architect to reduce damage of human lives and Properties caused by fire accidents in buildings. For this study, 7 buildings burnt by conflaguration in Seoul during the years of 1985 and 1987 are picked up, and 105 withnesses, who were present in one of them at them at fire, are traced for personal interview and respones to the written questionaire about 5 main issues; their perceptional behaviour, their emotional state at that time, their reactions to avoid danger, their escape routes, and their usual awareness to prevent fire. Some desirable measures suggested here are ;making Provisions to install fire centers in large buildings and underground structures in the fire fighting law, and requlating to compose fire units appropriate to the quantity of combustibles inside, limit the length of a blind corridor, furnish balustrade, and limit the width of the landing of the stairs in building code and regulations. Such measures should be considered from the time of planning to construct a building, and some drill and education in fire prevention is demanded for the occupants of the buildings too.

This study focused on the architectural, interior and management guidelines in rehabilitation center for visually impaired persons. For these purposes, we reviewed the movement behaviors and the characteristics of fire drill in rehabilitation center for visually impaired persons. The results are as follows. : First, the liner circulation paths and interior landmarks are recommended, and dwelling units and program rooms should be located in ground floor for barrier free evacuation. Second, It is important to establish continuous handrail, variations of paving patterns and materials, good color definition, tactile informations and directional sound. Third, it is necessary to serve more specified architectural, interior, and management guidelines according to impaired prototypes.

The purpose of this paper is to improve the evacuation stability of residents in apartment fire. For this purpose, the actual condition survey about the obstacles was conducted on 3,056 escape stairs in the 183 apartments. In addition, the questionnaire investigation was carried out a survey targeting the residents of apartments about their experience of fire safety education, perception on safety management of escape stairs, and perception on fire safety. As a result of investigation, we confirmed that the obstacles were formed in the 1,916 escape stairs among the 3,056 escape stairs of the 183 apartments (percent of barricades in escape stairs: 62.70%). Furthermore, it showed that fire safety education experience was found to be 83.10% of subject. The perception on safety management of the subjects in the escape step and the perception on fire safety were $3.84{\pm}0.75%$, and $3.49{\pm}0.61$, respectively. In the results, most of the subjects had a fire safety education and knew how to safety management the escape stairs but, the practice of the safety management action was low. Based on the results in the paper, the policy proposal is that the fire safety education is emphasized to change from the perception to action.

The occurrence a fire on a training ship with a large number of people on board can lead to severe casualties. Hence the Seafarers' Act and Safety Life At Sea(SOLAS) emphasizes the importance of the abandon ship drill. Therefore, in this study, the training ship of Mokpo National Maritime University, Segero, which has a large number of people on board, was selected as the target ship and the likelihood and severity of fire accidents on each deck were predicted through the preliminary hazard analysis(PHA) qualitative risk assessment. Additionally, assuming a fire in a high-risk area, a simulation of evacuation time and population density was performed to quantitatively predict the risk. The the total evacuation time was predicted to be the longest at 501s in the meal time scenario, in which the population distribution was concentrated in one area. Depending on the scenario, some decks had relatively high population densities of over 1.4pers/m², preventing stagnation in the number of evacuees. The results of this study are expected to be used as basic data to develop training scenarios for training ships by quantifying evacuation time and population density according to various evacuation scenarios, and the research can be expanded in the future through comparison of mathematical models and experimental values.

The Ministry of Public Safety and Security plans to expand fire safety education infrastructure to provide customized fire safety education, spread fire safety culture and develop a tailored fire safety education system as a part of the 2016 Citizens' Safety Improvement Policy. This study has also been designed to improve safety problems in the Republic of Korea. Even though safety education has been given, citizens aren't still able to experience a close-to-real situation. In addition, their understanding and satisfaction with the curriculum are very low. Therefore, this study offers VR fire-extinguishing experience education contents as an effective alternative. With a goal of having the participants experience fire extinguishing and evacuation drill in a virtual space, this program has the following advantages: i) safe fire-extinguishing experience; ii) UI to create fun ; iii) useful in fire-extinguishing education; iv) budget saving. we configure the VR fire experience system structure and hardware by applying UX design methodology. We also develop for VR-specific motion recognition plug-in and controller that can be feeling in HMD environment.
