이 논문에서는 재난 안전사고의 증가에 따른 인명 피해, 안전의식 저조 등을 방지하기 위해 스마트폰을 통해 쉽게 접할 수 있는 재난 안전사고에 대응하는 시나리오를 구현하는 모바일 어플리케이션을 구현한다. 기존의 사고 대응 시나리오와 관련한 모바일 어플리케이션들은 수가 적으며, 대부분 매뉴얼 형식으로 구성되어 있다. 따라서 이 논문에서는 지진이나 쓰나미와 같은 재난이나 일상에서 발생 가능한 안전사고 등의 다양한 시나리오들을 친근한 캐릭터들이 등장하는 진행하는 모바일 어플리케이션을 구현한다. 이 어플리케이션은 캐릭터를 통한 행동 선택지 형식으로 구성하여 연령대에 구애받지 않고 이용할 수 있으며, 명확한 대응방안을 제공함으로써 만일의 사고 상황에 올바른 대응할 수 있도록 한다.

Nuclear energy is considerably cheap and clean compared to other fossil fuels. Yet, there are rising safety concerns of nuclear power plants including the possibility of radiation releasing nuclear accidents. In light of the Fukushima nuclear crisis in 2011, Japan has been re-evaluating their existing energy policies and increasing the share of alternative energy. This paper first tracks the major historical changes of energy policy in Japan by time period. Next, energy security, reignited concerns and alternative energy are covered to examine Japan's energy security situation and its transition after the Fukushima disaster. Lastly, a short survey based on thematic analysis was conducted in South Korea and Japan to understand the public awareness of nuclear. This paper postulates that the case of Fukushima will contribute to establish and operate a safe-future nuclear program in South Korea, given that the country is not only geographically neighbouring Japan but also the world's fourth largest producer of nuclear energy.

A special purpose machine with two manipulators and quadruped crawler system is being developed to work at disaster sites where it is intended to quickly respond in the initial stages after the event. In this study, a terrain recognition module is developed so that the above special purpose machine can quickly obtain ground information to help choose its path while recognizing objects in its way, this is intended to enhance the remote driver's limited situational awareness. Terrain recognition modules were developed for two tasks (real-time path guidance, precision terrain measurements). The real-time path guidance analyzes terrain and obstacles while moving, while the precision terrain measurement feature provides more accurate terrain information by precisely measuring the ground in front of the vehicle while stationary. In this study, an air-cooled sensor protection module was developed so that the terrain recognition module can continue its vital tasks in the event of exposure to foreign substances, including scattered dust, mist and rainfall, as well as high temperatures.

Recently, the criteria for assessing industrial accidents have been replaced by the mortality rate. It was found that the number of deaths from excavation work was the highest among construction machinery. The risk assessment is being conducted, however the industrial accident mortality rate has not decreased. Accordingly, this study aims to provide the basic for the create of a risk assessment model specialized in construction work at excavator. It provides absolute value from the risk model which is capable of delivery the probability of a disaster. In addition, we provide a relative risk model that compares the risk through scores between detailed works. The relative risk model is combined by likelihood and severity; the likelihood indicates the frequency of accidents and the severity indicates seriousness of fatal accidents. A variable that reflects the conditions of the construction site was added to the risk assessment model based on past disaster cases. And using the concepts of probability and average, the risk assessment process was quantified and used as an objective indicator. Therefore, the model is expected to reduce disasters by raising the awareness of disasters.

On the basis of the guideline "2012-104(2012.9.26.)" notified by the ministry of employment and labor, this paper provided the baseline data and the improvement proposal in applying risk assessment to a construction site by group interview & survey of construction workers. The worker's awareness and action plan of safety and health were investigated by numerical analysis. From the result of group interview and the survey of construction workers, it was found that most of construction workers feel the danger during the work. The results also shows that risk assessment can help to change & raise the awareness of safety and to reduce the industrial disaster. In addition, simple safety management activity such as TBM & active education of safety will be necessary for safe workspace and the active TBT(tool box talk) which combines TBM & the education of safety will be also effective.

Context-awareness techniques in ubiquitous computing environment provide various services to users who need to get information via the analysis of collected information from sensors in a spatial area. Context-awareness has been increased in ubiquitous computing and is applied to many different applications such as disaster management system, intelligent robot system, transportation management system, shopping management system, and digital home service. Many researches have recently focused on services that provide the appropriate information, which are collected from Internet by different kinds of sensors, to users according to context of their surrounding environment. In this paper, we propose an abstraction model to manage the large-scale contextual information and their metadata which are collected from different kinds of in-situ sensors in a spatial area and are presented them on the web. This model is composed of the modules expressing functional elements of sensors using sensorML(Sensor Model Language) based on XML language and the modules managing contextual information, which is transmitted from the sensors.

This study aims to verify the impact of a metaverse-based safety education program on the fire safety awareness of elementary school students. Utilizing the National Fire Agency's 119 metaverse program, an educational program was implemented for two months, and the experimental group was examined using paired-sample t-tests, while comparisons with the control group were made using independent-sample t-tests. The results revealed statistically significant differences between the experimental and control groups in the area of fire prevention. Although no statistically significant differences were observed over time within each group, the overall average scores for the entire class improved across all areas. Based on these findings, the effectiveness of metaverse-based safety education is suggested; however, a significant difference compared to traditional education was not detected. The study concludes by exploring implications for considerations in the implementation of metaverse safety education in the future.

최근 노량진 수몰사고, 방화대교 붕괴사고 등의 대규모 건설재해가 끊이지 않고 발생하고 있다. 이에 건설공사 현장에서 재해 저감을 위한 다양한 공사참여자의 역할 및 책임이 중요한 요소로 인식되고 있는 실정이다. 건설 산업은 계획, 설계, 시공, 유지관리 단계를 거치면서 발주자를 비롯한 설계자, 시공자 등 다수의 행위주체들이 참여하여 공사목적물을 만들어 가는 일련의 과정이다. 그러나 현행 안전관리의 주체는 근로자를 직접 고용하는 원도급자인 시공사에게만 책임이 집중되고 최상위에서 의사결정 권한을 행사하는 발주자의 안전활동 참여는 배제되고 있다. 이에 본 연구는 각 공사참여자를 대상으로 안전활동에 대한 인식수준 및 실태에 대하여 파악하고, 이를 통해 발주자 중심의 안전관리체계에 대한 개선방안을 제시하였다.

어린이 보호구역은 교통사고의 위험으로부터 어린이를 보호하기 위해 학교, 보육시설, 학원 등과 같은 시설 가운데 지정된 일정 구간을 말한다. 어린이 보호구역은 1995년 9월 제정된 이래, 2021년 1월까지 총 9번의 개정을 통해 강화가 됐음에도 어린이 보호구역 사고는 줄어들지 않고 있다. 본 논문은 방재디자인 기반의 어린이 보호구역 표준모델을 제시하고자 하였다. 연구의 방법으로는 문헌조사, 실증조사, 인식도 조사를 진행했다. 인식도 조사 대상은 어린이, 학부모, 운전자를 대상으로 조사를 진행하였다. 환경 조사 대상으로는 횡단보도, 자동차도로, 보행자도로, 신호등을 대상으로 조사하였다. 조사 결과 차량 운전자의 어린이 보호구역 시각적 인지가 어렵다는 점이 발견되었고, 보행자 도로를 이용하는 오토바이가 어린이에게 매우 위협적인 요소로 다가왔음을 알게 되었다. 이에 따라 방재디자인 중심의 개선된 어린이 보호구역 표준모델 디자인을 제시하였다.
