Currently, autonomous vehicle markets are commercializing a third-level autonomous vehicle, but there is a possibility that an accident may occur even during fully autonomous driving due to stability issues. In fact, autonomous vehicles have recorded 81 accidents. This is because, unlike level 3, autonomous vehicles after level 4 have to judge and respond to emergency situations by themselves. Therefore, this paper proposes a vehicle crisis detection system(VCDS) that collects and stores information outside the vehicle through CNN, and uses the stored information and vehicle sensor data to output the crisis situation of the vehicle as a number between 0 and 1. The VCDS consists of two modules. The vehicle external situation collection module collects surrounding vehicle and pedestrian data using a CNN-based neural network model. The vehicle crisis situation determination module detects a crisis situation in the vehicle by using the output of the vehicle external situation collection module and the vehicle internal sensor data. As a result of the experiment, the average operation time of VESCM was 55ms, R-CNN was 74ms, and CNN was 101ms. In particular, R-CNN shows similar computation time to VESCM when the number of pedestrians is small, but it takes more computation time than VESCM as the number of pedestrians increases. On average, VESCM had 25.68% faster computation time than R-CNN and 45.54% faster than CNN, and the accuracy of all three models did not decrease below 80% and showed high accuracy.

21세기에 인류는 먹는 문제로 해서 어느 때보다 심각한 위기에 직면할 것이다. 유엔 식량농업기구(FAO)는 최근 세계 곡물재고량이 계속 감소되어 최소 안전기준인 소비량의 17%에도 못미치는 수준에 있으며 이미 북한을 비롯한 38개국이 극심한 식량위기에 직면해 있다고 경고하고 있다. 이같은 세계적인 식량위기 상황 속에 21세기 한국의 식량문제는 어떠하며 식량위기를 극복하기 위한 첨단기술의 현황을 점검해 보았다.

The purpose of this research is to figure out the effects of media framing and image restoration strategies on the public's crisis perceptions. The literature review revealed that the public perceives crises through the media lens and image restoration strategies heralded by the organization interact with media frames in the process of the public's perceiving the crisis. The news content analysis and the experiment were conducted to accomplish the research purpose. Also food-related crises were selected for a research case because they have a great impact on the society. The content analysis showed that image restoration strategies designed by the crisis organization tend to be conveyed through anecdote-type news frames. Most image restoration strategies were close to defensive communications and not differentiated by the crisis type. The experiment outcomes demonstrated that the organization's image restoration strategies were not consistent with what the public preferred in the crisis situation. Such public perceptions also were changed according to media frames. Media frames and image restoration strategies have an interaction effect on the public's crisis perception.

Modern society is exposed to various types of crises. In particular, since the September 11 attacks, each country has been increasingly responsible for managing non-military crises. Therefore, the purpose of this study is to consider ways to utilize artificial intelligence(AI) for national crisis management in the era of the fourth industrial revolution. To this end, we analyzed the effectiveness of artificial intelligence(AI) operated and under research and development(R&D) to support human decision-making and examined the possibility of using artificial intelligence(AI) to national crisis management. As a result of the study, artificial intelligence(AI) provides objective judgment of the data-based situation and optimal countermeasures to policymakers, enabling them to make decisions in urgent crisis situations, indicating that it is efficient to use artificial intelligence(AI) for national crisis. These findings suggest the possibility of using artificial intelligence(AI) to respond quickly and efficiently to the national crisis.

For over 60 years, public libraries in Korea has made an essential contribution to the social, educational, cultural well-being of local communities throughout the country. In spite of these contributions, the public library is regarded as being in crisis. If the current crisis is serious situation, the library and librarian should seek ways to overcome the such crisis. The aim of the paper is to analyse the various factors of the current crisis through an fish-bone diagram and to suggest the solutions to overcome the crisis.

일본최대의 기업 NTT는 민영화 5년째를 맞이하면서 심각한 위기에 직면하고 있다. 지난해말 리쿠르트 파문으로 신토 전회장의 사임으로 시작된 NTT의 위기는 분할론에 휩싸이면서 주가폭락등으로 이어져 상황은 더욱 악화일로에 있다. 우정성이 미 ATT분할이 성공적이었다는 평가를 내리고 NTT분할에 긍정적 입장을 취하고 있는데다 여론과 국민까지 분할을 지지하고 있는 상황이어서 앞으로 NTT의 향방은 일본내 뿐만 아니라 세계적 관심으로 부상하고 있다. "NTT는 과연 어떻게 될 것인가?" NTT 분할에 대한 일본 각계의 시각을 종합해 본다.

Since the 1960s, the United States' (U.S.) deinstitutionalization policy has reinstated people with mental illness into communities. Unfortunately, when untreated, some people with psychiatric disorders become homeless, and some commit serious crimes during a psychological crisis. Assisted Outpatient Treatment (AOT), also known as Kendra's Law in New York and Laura's Law in California, provides treatment, services and support to people with mental illness in the community. AOT has repeatedly been found effective and is recognized as an evidence-based practice. The response to the mental health crisis (crisis intervention) in the U.S. has also been successful in preventing worsening mental illness and related criminality and other issues. This paper provides an opportunity to create a platform from which to learn how to successfully apply the AOT and crisis intervention of the U.S. to South Korea within the cultural and societal context when establishing social services for people with mental illness in South Korea's communities.

The purpose of this study is to provide practical implications on government crisis management strategies and on the use of SNS in crisis management. Specifically, this study analyzed Ministry of Drug and Food Safety's responses to paraben toothpaste issue, media coverage of paraben toothpaste issue, and public responses to paraben toothpaste issue. Through textual analysis and the network analysis of 45 news articles and 645 tweets, this study found that Ministry used one-way communication strategy and mostly negative issues regarding Ministry's crisis response strategies were diffused via the media and Twitter. This study was meaningful in that it highlighted the importance of media relations and use of SNS in crisis management. The findings of this study provide useful implications for government officials and PR practitioners in their crisis management and communication strategy.

The present study examined the factors influencing individuals' risk information seeking and processing using the case of 2015 MERS outbreak in Korea. Analyses of two-wave online panel data demonstrated that perceived risk, negative affect, subjective norm, and information insufficiency predicted the risk information seeking/avoiding as well as information processing mode, which validates the Risk Information Seeking and Processing(RISP) model. More importantly, this study found new evidence that information seeking and systematic processing promoted MERS preventive behaviors. In addition, active SNS use moderated the link between perceived risk and negative affects about MERS crisis as well as the relationship between social normative pressure and to seek the risk related information.
