The 'alert' is to provide a signal or information beforehand, in order to prepare against situations in which abrupt incidents or disasters are expected. In other words, the purpose of alert is to help people or respondents to take precautions against and quickly cope with disasters or incidents, before those actually occur. This paper draws requirements of alert system from definitions of the alert and cases of it home and abroad. Following requirements of alert system are derived to allow subjects responsible for alert issue to quickly handle changes of situations; 1) identification of subjects responsible for alert issue, 2) use of definite terms regarding alert levels, for prompt actions, and 3) distinct separations among alert levels. This paper suggests improvement directions by extracting several problems of National Crisis Alert System according to such requirements.

This study tried to suggest crisis management compliance to prevent personal information infringement accidents that may occur in the process because the data including personal information is being processed in the artificial intelligence (AI) service process. To this end, first, the AI service provision process is divided into 3 processes such as service planning/data design and collection process, data pre-processing and purification process, and algorithm development and utilization process. And 3 processes are subdivided into 9 stages following to personal information processing stages to infringe personal information. All processes were investigated with literature and experts' Delphi. Second, the investigated personal information infringement factors were selected through FGI, Delphi, etc. for experts. Third, a survey was conducted with experts on the severity and possibility of each personal information infringement factor, and the validity and adequacy of the 94 responses were verified. Fourth, to present appropriate risk management compliance for personal information infringement factors in AI services, a method for calculating the risk level of personal information infringement is prepared by utilizing the asset value of personal information, personal information infringement factors, and the possibility of infringement accidents. Through this, the countermeasures for personal information infringement incidents were suggested according to the scored risk level.

This study is about the development of emergency response guidance by safety index of seakeeping performance which is based on emergency response procedures in the ship through HAZID. These emergency response guidances will contribute to respond ship's abnormal conditions related to seakeeping performance effectively and efficiently to reduce marine accidents.

해상교통혼잡도와 선박사고는 연관성이 높다. 이에 본 논문은 자본 등의 이유로 위기상황 대응에 취약한 소형 선박에 특정된 위험을 인식하고, 유사시 일부 선착장으로 선박이 집중되는 것을 방지하기 위한 시스템을 제안한다. 안드로이드 APP과 클라우드 서비스, 알고리즘을 통해 최적의 정박지 및 경로를 제공함으로써 소형 선박이 향후 위기상황에 효과적으로 대응할 수 있을 것으로 기대한다.

경제성장과 국민소득의 증대에 따른 교통수요의 증대는 필연적으로 자동차 대수의 증가를 초래하게 되었다. 교통은 국가산업의 발전, 지역 간의 격차해소 및 문화교류에 기여하고 있으며, 작게는 국민의 일상적인 대중 교통수단으로서의 역할을 맡아 개인생활의 향상에 이바지하고 있다. 그러나 이러한 교통의 양적 발달의 이면에는 교통사고라는 부정적인 요소를 내포하고 있으며, 우리나라의 경우 유래 없이 높은 교통사고율로 말미암아 교통사고로 인한 재해의 위기에 처해 있다하여도 과언이 아니다.(중략)

본 논문에서는 위험지역 주위의 사고 관련 상황 인지를 위한 정보 수집 방안을 고려한다. 사고 상황에 대한 인지는 위험상황에 대응하기 위한 것으로 위기에 대한 신속한 대응을 처리하도록 유도한다. 위험지역에서 수집된 정보가 특정상황에 대한 인지로 연결되기 위하여 각각의 상황을 실시간으로 분석해야 한다. 이것을 위하여 위험지역에 대한 정보수집 방안을 설계하도록 한다.

An emergency manual is designed to minimize the extent and effect of lives and assets; it is not designed to prevent an accident. There have been continuous arguments in terms of manual effectiveness regardless of the fact that much effort and great cost have been invested in emergency planning and operations. The problems are that there are a number of different emergency manuals, that these manuals are hard to understand and rarely used due to their complexity, that they provide little direction toward the taking of action, and that coordination is difficult between those involved; all of these problems are related to two different pieces of legislations that define emergency manuals in different ways in terms of the contents required. The study has tried to respond to these arguments by exploring relevant legislation to identify emergency manuals that can be used to respond to rail incidents/accidents, for which previous responses have seemed inefficient. Further, some parts of the emergency manual contents are found to overlap, including the ways of differentiating incident responses, personnel roles and responsibilities by types of accident, and threat levels, all of which has resulted in unnecessary pages of the manuals. In preparing and operating such manuals, this study recommends that one piece of legislation that directly affects rail undertakings must be applied in an effort to increase effectiveness.

In response to Incheon tap water accident in 2019, the Ministry of Environment has created the "Comprehensive Measures for Water Safety Management" to improve water operation management, provide systematic technical support, and respond to accidents. Accordingly, K-water is making a smart water supply management system for the entire process of tap water. In order to advance the response to water accidents, it is essential to secure the reliability of real-time water operation data such as flow rate, pressure, and water level, and to develop and apply a warning algorithm in advance using big data analysis techniques. In this paper, various statistical techniques are applied using water supply operation data (flow, pressure, water level, etc) to prepare the foundation for the selection of the optimal operating range and advancement of the monitoring and alarm system. In addition, the arrival time is analyzed through cross-correlation analysis of changes in raw water turbidity between the water intake and water treatment plants. The purpose of this paper is to study the model that predicts the raw water turbidity of a water treatment plant by applying raw water turbidity data considering the time delay according to the flow rate change.

21세기 지식 기반 사회를 준비하기 위한 신교육의 방향은 교사 중심의 교수 교육(teaching ed.)과 학생중심의 학습 교육(learning ed.)에서 교사와 학생이 함께 주도하는 사고중심 교육(thinking ed.)으로 옮겨가고 있다. 그리고 수학은 우리의 마음에 존재하는 모든 관념적 대상을 다루는 도구로서, 인간 사회의 여러 분야에서 인간의 사고를 도우며 인간이 직면하는 어려운 문제들을 합리적으로 풀어 나갈 수 있는 능력을 키우고 또 항상 새로운 것을 창조하는 학문이다. 이와 같이 창의적 사고를 필요로 하는 신교육 사조와 창조적 사고를 특정으로 하는 가장 유용하고 매력적인 수학은 본질적으로 서로 맥을 같이 하고 있다. 이런 관점에서 21세기 수학교육의 필요성은 더욱 중대되어 가고 있는 것이 국제적 추세이다. 그럼에도 불구하고 공교육 위기설이 나돌고 있는 우리 나라 중등교육 현장에서 수학교육의 나아갈 길은 과연 무엇인가?

The study, on the one hand, reflects the recent social interest in crisis management including user safety and library disaster preparation, and, on the other hand, presents a detailed safety management manual that is a reference for library work sites concerning accidents that may occur in public libraries. The proposed safety management manual consists of safety management elements for the four areas of 'safety management planning', 'safety management for each crisis type', 'information resource restoration', and 'safety management checklist', as well as their detailed sub-categories. This allows each public library site to use the manual to establish safety management plans according to their situation and educate their employees.
