This study simulates and compares the evacuation time and characteristics according to the living patterns on board a training ship which was launched in Dec. 2005, on the viewpoint of the various activities being possible on board a cruise ship. Based on interviews with personnels on board, 3 living patterns are set as representative living conditions; Pattern A(all personnels are positioned at their cabins), Pattern B(all personnels are positioned at lecture rooms, offices or else), Pattern C(all personnels are positioned at restaurant or cafeteria). The simulation results show that Pattern B is comparatively ideal because the evacuation time is short and there is less delay of personnels' movement on each deck. On the contrary, Pattern C is evaluated as the worst because the average evacuation time took more than 360 seconds and the bottle-neck happened at Upper deck. As a result, this study proposes the needs of various countermeasures against the fire and/or disaster, considering the various living patterns on cruiser(s) and/or passenger ship(s).

본 연구는 국내의 고령화 추세와 고령자시설 현황을 고찰하고 일반인과 고령자의 군집형성시 보행속도를 측정하여 고령자를 고려한 피난안전설계의 기초자료로 제시하기 위한 연구이다. 군집보행속도 측정결과 고령자가 전방에 배치되었을 때 평균 0.81m/s로 가장 감소하였으며, 고령자 비율이 증가할수록 전체 보행속도는 감소하였다. 향후 피난안전설계를 위하여 고령자의 피난행동특성을 고려한 다양한 연구를 통한 DATA 확보가 필요할 것으로 판단된다.

전 세계적으로 평균수명이 연장되고 있으며 고령자의 수가 증가하고 있는 가운데 특히 국내는 빠르게 고령화 사회로 진입하고 있다. 그러나 건축물 화재시 일반성인보다 피난이 난해한 고령자가 거주하는 시설의 피난안전규정은 제대로 이루어지지 않고 있으며 구체적인 방안 또한 미흡한 실정이다. 따라서 본 연구에서는 시니어장비를 이용해 일반성인과 고령자의 자유보행속도 및 군집형성시 보행속도를 조사하여 재해약자의 존재가 전체의 보행에 미치는 영향을 파악하고 향 후 고령자, 유아등 재해약자의 피난안전을 위한 방안의 기초 DATA의 자료로 사용하고자 한다.

Korea is rapidly becoming an aging society. As a basic research on increasing evacuation safety design at silver facilities, the study was conducted in consideration of different foot's pace according to the number of seniors and their locations in a crowding of ordinary people and seniors all together. When the seniors were located at the front, the pace reduced to 0.81m/s on average. With 10 seniors which covered 50% of the crowd, the pace decreased to 0.85m/s. It is true that Korea has no existing researches on evacuation behaviour, and functions mentioned in its evacuation safety design is lack of practicality. Therefore, it is certainly necessary to secure any data of the evacuation behavior through various studies on seniors' evacuation behaviors.

본 연구는 고령자시설의 현황과 고령자의 군집보행속도를 조사한 전보에 이어 고령자를 고려한 피난안전설계를 위한 기초연구로서 노인요양시설의 근무자의 소방안전관리실태에 관한 설문조사를 실시 및 분석하였으며 그 결과 화재시 재실자의 피난가능여부와 소방서와의 연락체계에 관한 질문에서 초기피난의 문제점을 도출할 수 있었으며 노인요양시설의 비상구 및 주야간 상시 관리자 수 및 피난시설에서 대응책이 필요할 것으로 사료되어 향후 체계적인 피난안전계획의 구축이 필요할 것으로 판단된다.

Purpose: The purpose of this study is to present an evacuation performance analysis model that can derive vulnerable evacuation spaces with considering the movement behavior as per the elderly groups in the event of a fire in a geriatric hospital. Methods: The evacuation characteristics of geriatric hospital users were investigated through the review of precedent studies. First, the occupant conditions and the evacuation scenario were set to analyze a study target hospital. Then, the evacuation simulation was carried out considering the group types and the density of each group. Finally, an evacuation performance analysis model according to the group type was presented based on the simulation results. Results: The results of this study are as follows: (1) The evacuation performance according to the group type is to be clarified through the suggested study model. (2) It is necessary to secure a ramp or an emergency elevator to distribute the evacuation personnel at the design stage because congestion occurs due to collisions between evacuees on the stairs and delays the evacuation time. (3) It is necessary to consider the evacuation stairs and openings of sufficient size by analyzing the frequency of congestion occurrence and the escape routes of occupants in advance to identify the space where the evacuation flow overlaps. Implications: It is expected that the study result is to be used as primary data for studies that consider the elderly and clustering evacuation behavior in the event of a fire in a geriatric hospital.

Recently the consideration for occupant's security has been raised as very important design element from the fire by building's large sized, higher storied, and its compounded. But the domestic laws regulated the predicative laws according to the technical standard which has no difference from the past domestic evacuation regulation. Therefore, regulation of escape code and developing technology for Korean conditions are needed to reduce victims during disaster by protecting occupant and guiding people to safe places.

This study developed an algorithm to predict the most efficient evacuation protocol in an elementary school that has an irregular type of architectural planning. The assumption of this study takes a stand point that today's elementary schools are designed in unusual and irregular floor type and, therefore, past architect's knowledge regarding efficient evacuation will no longer effective to save lives. In this regard, this study applied an algorithm that is especially designed to find appropriate locations in general in the field of industrial engineering, which has been proven for many decades. Furthermore, this study not only adapted an engineering model but also conversed to examine spatial relationship and added the concept of group evacuation, which will delay the whole evacuation process, in the tested algorithm to make it more architectural. Consequently, this study compared its outcome with an existing elementary school and questioned its effectiveness in evacuation process based on the algorithm.

This study predicts and compares the evacuation times of a training ship, which is easily influenced by gathering patterns of crews' onboard life style. As the results, the evacuation times of the high density, like meal time, take 1.5 times longer than the low density, like normal time. And it is also evaluated that the evacuation times of high density affected by evacuation speeds show 4 times higher than the low density.

The effort of transferring some parts of urban functions to the underground space is growing trend among modem cities because of the limit of horizontal land use, the rise of land value, the diversification of human desire, etc. Thus, the basement of building and the subway station have deepened. It calls our attention to safety about evacuation from the underground space to the ground. Until now, the study about crowding walk in stairs has been progressed, focusing on the crowding walk that is going down the stairs, and there is no study about crowding walk that is going up the stairs. This study measured walking pace by crowd density that is going up the stairs in the subway station stairs making one-way movement of crowd. The actual survey showed that the mathematical relation 'V=0.638-0.0949p' determines going up walking velocity at a gradient of $23^{\circ}$, and the mathematical relation will be 'V=0.597-0.1067p' at a gradient of $30^{\circ}$, when it is converted, based on the average walking velocity of crowd by the slope of the stairs which is recommended by Architectural Institute of Japan.
