The government of South Korea has made great efforts in the area of railway safety management by means of a railway safety law and an integrated railway safety plan established in 2004 after the Daegu subway fire accident. However, after certain railway incidents, a reactive railway safety management system has been implemented that has led to fatal accidents caused by the collision, derailment, and fire every year. Hence, this study is intended to propose a framework that integrates data from distributed detection devices into a real-time railway safety monitoring and control system for proactive safety management. Furthermore, we will provide a future development direction for safety performance monitoring indicators to determine whether the railway safety monitoring and control system works effectively. The proposed framework is expected to be a cornerstone for the real-time railway safety monitoring and control system to be implemented in the future.

Globally, various disasters such as typhoons, floods, earthquakes, fires, explosions have caused work to be halted. If there is a large-scale disaster at public institutions in charge of major national affairs and their works are interrupted, not only will there be property damage, but there will also lead to a decline in national credibility and direct and indirect impacts on the people. Therefore, it is necessary to ensure continuity of operation by minimizing the interruption period of critical operations due to disasters. Overseas advanced countries such as the United States and Japan developed guidelines for Continuity of Operation (COOP) to prevent unexpected work disruptions caused by disasters. Recognizing the necessity of COOP in South Korea, a relevant law has been newly established in 「the Framework Act on the Management of Disasters and Safety」 to enable public institutions to establish the COOP in response to this situation. In this study, the definition, the necessity and overseas cases of COOP were investigated and described. Using the templates developed by these results, operational impact analysis, risk assessment, operational continuity strategies and operational continuity procedures were applied to "A" City Hall in Gyeonggi-do province and those results were described. The objective of this study is to substantially contribute to the introduction of COOP to local governments through their pilot application and implications of COOP.

The comprehensive natural disaster reduction plan, the highest plan in the disaster prevention field, was implemented by local governments. second plan is currently being formulated. In order to minimize human and property damage, structural and non-structural measures for each of the nine disaster types are established and implemented for 10 years. Structural measures are based on engineering and quantitative analysis, and the criteria for setting reduction measures are clear. Non-structural measures, however, currently lack the set criteria. the basic disaster and safety management law included the safety vulnerable class in 2018. Currently, the safety vulnerable class of the detailed establishment criteria of the comprehensive natural disaster reduction plan is being established, including children, the elderly, and the disabled. However, due to the lack of data securing and database construction by local governments, it is difficult to prepare a location map for establishing reduction measures for the safety vulnerable. Therefore, in this study, OPEN API data of the safety vulnerable class were collected and statistical information and GIS of SGIS information services were used. The distribution diagram of the safety vulnerable class in Samcheok, Gangwon-do, which is a sample area, and the distribution diagram of the safety vulnerable class in units of the output area (OA) in Geundeok-myeon were prepared.

Public sports facilities, which have increased in number due to continued government attention and investment, are used by a large number of residents in the province. However, the safety management in some facilities is limited due to being carried out with reference to safety management standard manuals as a mere formality. The purpose of this study was to analyze the current safety management status of public sports facilities in Gangwon and to seek out a policy direction that can be used safely by provincial residents. To this end. the study made a comprehensive review of central government and Gangwon government policy trends in sports facility safety management in Gangwon along with actual cases, from which it made the following suggestions for policy directions. First, it proposed the designation and operation of specialized institutions using locally established development and municipal companeie,. universities and cooperatives. and the training and fostering of safety managers for sports facilities. Secod, it proposed the establishment of a foundation to promote a sport facility safety culture such as designation of and commendation for excellent facility safety management on the provincial level. holding case presentations on safety and responsiveness. sports safety experience plazas, sports safety classes, and cartoons for public relations. Third, it proposed setting the foundation for a safety management system that takes into account the greater quantity of leisure sports facilities compared to other cities and provinces. Fourth, it proposed the establishment of an institutional basis to establish support ordinance for sports facility safety management that meets the local conditions in Gangwon. Fifth, it proposed safety management measures for sports facilities at the central government level in parallel with a basic plan for sports facility safety management tailored to Gangwon that matches the conditions on the ground in the region.

수문순환과 수질오염과정의 제반 기작들이 완벽하게 규명되지 않은 상황에서 인위적 또는 자연적 조건에 따른 수질의 평가는 수질모형으로서 추정하는 것이 유일한 대안이며, 다양한 관리대안에 따른 수질환경변화를 예측함으로서 합리적인 관리방안을 도출하는데 유용한 수단이 되고 있다. 현재 시행 중인 수질오염총량관리제에서 또한 수질모형은 핵심적인 역할을 담당하고 있으며, 보다 구체적으로는 단위유역의 목표수질을 결정하는 것에서부터 기본계획 또는 시행계획에 따른 오염부하량 등 환경요인의 변화와 이에 따른 목표수질 설정지점의 수질 변화 등을 모의하는데 이용되고 있다. 그러나 모형에 사용되는 입력 매개변수의 불확실성과 이에 관련된 수질 모형 자체의 불확실성은 수질오염총량관리제와 같이 많은 이해당사자가 관여된 정책의 결정 시에는 공학적으로 많은 부담으로 작용하고 있는 것 또한 현실이다. 실제로 미국의 오염총량관리제의 경우를 살펴보면 모형의 불확실성 분석이 전체 과정의 진행에서 가장 핵심적인 지위를 차지하고 있다고 볼 수 있다. 많은 연구들이 수질모형에 있어서의 불확실성을 정량화하기 위하여 수행되어 왔으며, 특히 미국의 오염총량관리계획의 수립 시에는 이러한 불확실성 분석을 토대로 하여 안전율을 산정하도록 되어있다. 그러나 이러한 연구들의 대부분은 수질모형의 매개변수 중 수질기작에 관련된 매개변수들(예를 들어, DO, BOD, N, P 등에 대한 반응계수)에 대한 연구에 집중되어 있다. 하천의 수질을 적절하게 모델링하기 위해서는 이러한 수질에 직접적으로 관련한 매개변수들 이외에 하천의 수리특성에 관한 올바른 이해를 바탕으로 그와 관련된 수리학적 매개변수들에 대한 연구가 뒷받침되어야 한다. 그동안 수행되어온 수질 모델링의 적용 사례를 살펴본 바에 따르면 하천을 모델링하기 위해서는 현장 특성 자료의 중요성, 특히 하천수리특성에 관련된 기초 자료의 가용성 여부가 모형의 성패에 매우 중요한 역할을 함을 알 수 있다. 이는 유량, 유속 및 폭과 깊이로 대변되는 하천 지형은 물질 이송에 대한 주요 외력 함수이며, 다른 모든 예측치들은 이들에 의존적일 수밖에 없기 때문이다. 따라서 이들의 정확한 표현은 올바른 수질 예측에 있어서 필수적일 수밖에 없다. 많은 모형매개변수들이 유속과 깊이에 의존적이나, 이들에 관한 정보는 종종 현장관측에서 조차 무시되는 경우가 많다. 이에 본 연구에서는 수질모형의 매개변수 중 특히 수리특성에 관련된 매개변수들이 수질에 미치는 영향을 파악하는 것을 목적으로 하고 있다. 이를 위해 적용된 수질모형은 QualKo를 사용하였으며, 대상 하천은 낙동강 본류 경남구간 시점 부근인 회천 합류 전부터 낙동강 본류 경남구간 종점 부근인 밀양강 합류 전까지의 경남 오염총량관리 기본계획 시 구축된 모형 매개변수를 바탕으로 분석을 수행하였다. 일차오차분석을 이용하여 수리매개변수와 수질매개변수의 수질항목별 상대적 기여도를 파악해 본 결과, 수리매개변수는 DO, BOD, 유기질소, 유기인 모든 항목에 일정 정도의 상대적 기여도를 가지고 있는 것을 알 수 있었다. 이로부터 수질 모형의 적용 시 수리 매개변수 또한 수질 매개변수의 추정 시와 같이 보다 세심한 주의를 기울여 추정할 필요가 있을 것으로 판단된다.

Although the school-age population is continuously decreasing, the number of people eligible for special education is increasing every year. Special schools, which are comprised entirely of students with special education needs, are vulnerable due to restrictions on evacuation in the event of a fire. However, the characteristics of special schools are not reflected in the plans related to firefighting and safety in special schools. In this study, essential items such as placement of helpers were selected through analysis of firefighting and school safety plans and collection of faculty and staff opinions. Afterwards, through analysis of experts' opinions, a basic fire evacuation scenario was presented that reflected the characteristics of special schools. We hope that this scenario will contribute to the development of customized fire evacuation scenarios for each special school in the future.
