Development of Disaster Simulator "Legends of KAWAUCHI" as a Disaster Response Training Software: Overcoming the COVID-19 Pandemic

A. Hasegawa, M. Kato, K Iyama (Fukushima Medical University, Japan)


Background

It is one of our important missions to hand down the lessons learned by the responders of the Fukushima disaster. As a part of this mission, we have held three face-to-face disaster response training sessions in Kawauchi Village for both domestic and international students to deal with unclear hazards. However, due to the recent COVID-19 pandemic, face-to-face training has become difficult.


Objective

The purpose of this project is to develop a means to practice medical response to unclear hazards in a non-face-to-face setting and to continue to hand down the lessons of the Fukushima accident to the next generation.


Methods

We developed the Disaster Simulator "Legends of KAWAUCHI" as a disaster response training software. The contents of the software were developed by the Department of Radiation Emergency Medicine of Fukushima Medical University and the Kawauchi Branch of the Futaba Fire Department, and the software was produced by Mark-on Ltd. The above software was developed with a grant from the R2 Science and Research Support Program (a project to promote the Fukushima Innovation Coast Project using the "reconstruction wisdom" of universities and other institutions). And the above was used in a webinar "Emergency response for the uncertain hazard" hosted by the Fukushima Medical University on October 19-21, 2020.


Results

Fourteen students participated in the webinar. There were 10 domestic participants, 4 international participants, 4 Japanese and 10 foreign participants. We provided the participants with three scenes on the software: disaster scene rescue, triage, and medical first aid station, built on a screen. The participants were able to manipulate their own avatars to select and evaluate any detector and monitor, set up any protective clothing and equipment at any location, lay out the scene, and then share the above information in real time with other participants on a screen. Participants practiced each of the following items in groups: command and control, safety management of self-scene-survivors, communication, assessment, triage, treatment, and transport using the above. They were also able to compare the results of their own group with those of the other groups.


Discussion

We developed software to hand down the disaster response experience of the Fukushima accident. The software developed by us is not able to replace all the effects of face-to-face practical training. However, it was found to be at least sufficiently effective as a substitute for the desk-based face-to-face exercises. Even in the event of a COVID-19 pandemic, we would like to continue to innovate measures to maintain the quality of education in the future. And we would like to continue to pass on the lessons of the Fukushima accident in the future.

災害対応訓練ソフトウエアとしてDisaster Simulator "Legends of KAWAUCHI"の開発 -COVID-19パンデミックを乗り越える

長谷川 有史、加藤 美喜子、井山 慶大 (Fukushima Medical University, Japan)


背景

福島事故の災害対応者が得た教訓を伝承することは我々の重要な使命の一つである。その一環として、我々は川内村において、国内外の学生に対して不明確なハザードに対する災害対応実習をこれまで3回開催してきた。しかし昨今のCOVID-19パンデミックにより対面実習が困難となったため代替手段を模索してきた。


目的

不明確なハザードに対する医療対応実習を非対面で行うための手段を開発し、福島事故の教訓を伝承し続けること。


方法

我々は災害対応訓練ソフトウエアとしてDisaster simulator ”Legends of KAWAUCHI ”を開発した。その内容は福島医大放射線災害医療学講座と双葉広域消防本部川内分署で策定し、製作は(株)Mark-onに委託した。上記はR2学術研究活動支援事業補助金(大学等の「復興知」を活用した福島イノベーション・コースト構想促進事業)の補助を受けて作成した。上記を2020年10月19-21日に当学が主催したWebセミナー「Emergency response for the uncertain hazard」で実運用した。


結果

セミナーには14名の学生が参加した。その内訳は国内参加10名、国外参加4名、日本人4名、外国人10名であった。我々は参加者に、災害現場救助、トリアージ、医療救護所のPC上に構築された3つのシーンをソフトウエア上で提供した。参加者は、画面上で自分自身のアバターを操作して、任意の検知器やモニター選択と状況評価を行い、任意の防護衣や防護資器材を任意の位置に設定してシーンレイアウトを行い、上記を参加者間で同時共有できた。参加者はセミナーでCommand and control, Safety management of self-scene-survivors, Communication, Assessment, Triage, Treatment, Transport の各項目をグループ実習し、他のグループの内容と比較できた。


考察

福島事故の災害対応経験を伝承するためのソフトウエアを開発した。我々が開発したソフトウエアでは、対面実習で得られる全ての効果代替できる訳ではない。しかし、少なくとも対面机上演習の代替手段としては十分に効果を発揮できると考えられた。COVID-19パンデミックの状況でも、教育の質を維持する対策を講じ福島事故の教訓を伝え続けてゆきたい。
