This study applied LDA topic modeling analysis to collect and analyze news media big data related to face masks in the three waves of the COVID-19 pandemic in Korea. The results empirically show that media reports focused on mask production and distribution policies in the first wave and the mandatory mask wearing in the second wave. In contrast, more reports on trivial, gossipy events consist of the media coverage in the second and third waves. The findings imply that Korea's governmental interventions to address the shortage of face masks and to regulate mask wearing were successful relatively in a short time. In contrast, the study also reports that there may be relative less number of science-based news reports like the ones on the effectiveness of face masks or different levels of filter types. This study exemplifies how a big data analysis can be applied to evaluate and enhance public health communication.

2005년 9월 26일 컨테이너선 Cast Prosperity 호와 탱커선 Hyde Park은 Quebec 주 Trois-Riveres 로부터 남서쪽으로 12마일 떨어진 Lac Saint-Pierre 의 Channel 을 통과하던 중 충돌한다. Cast Prosperity 호는 VDR(Vessel Data Recorder)를 탑재하고 있었고 이 VDR의 기록과 양 선박의 AIS 기록을 토대로 사고를 재현하게 된다. 또한, 선주사로부터 제공된 자료를 바탕으로 사고 선박의 Database 및 사고 해역의 Database를 제작하여 ECS 의 항해 기록 및 각종 기상 Data 를 활용하여 사고 당시 선박의 항해과정을 3차원 영상으로 재현하여 사고의 원인을 규명한 사건이다.

운수 회사의 사업장 소재지나 이 사건 차량의 차고지 및 원고의 주거지 관계에 비추어 원고가 이 사건 차량 이외에 청주나 송탄사료공장까지 출 퇴근하는 방법이 있었다고 보이지 않고, 그에 따라 원고의 입사 당시 사업주가 이 사건 차량을 원고의 주거지 부근에 주차한 후 이를 이용하여 청주나 송탄사료공장으로 가서 사료를 공급받아 업무를 수행하도록 용인하였던 점, 그에 따라 이 사건 차량에 대한 관리 이용권이 전적으로 원고에게 전담되어 있었고, 원고의 주된 업무가 빈 화물차량을 운전하여 사료공장으로 가서 사료를 공급받은 후 각 양계농장에 사료를 운반 배송하는 업무로 이러한 업무내용이나 근무형태 등에 비추어 원고가 화물차에 탑승하여 운전을 개시하는 때로부터는 업무수행이 시작되어 사업주의 지배 관리하에 있다고 보이는 점(원고가 자택에서 이 사건 차량에 도착할 때까지가 출근에 해당하고, 그 이후 차량에 탑승한 이후에는 바로 업무의 개시가 있었다고 할 것이다) 등에 비추어 보면, 원고가 재해 당일 새벽 청주사료공장으로 가기 위하여 이 사건 차량을 운전하다가 발생한 이 사건 재해는 업무상 재해라고 봄이 상당하다.

A number of maritime accidents, and accident response activities, including the command and control procedures that were implemented at accident scenes, are analyzed to derive useful information about responding to maritime accidents, and to understand how the chain of events developed after the initial accident. In this research, a new concept of a 'risk based accident response support system' is proposed. In order to identify the event chains and associated hazards related to the accident response activities, this study proposes a 'Brainstorming technique for scenario identification', based on the concept of the HAZID technique. A modified version of Event Tree Analysis was used for quantitative risk analysis of maritime accident response activities. PERT/CPM was used to analyze accident response activities and for calculating overall (expected) response activity completion time. Also, the risk based accident response support system proposed in this paper is explained using a simple case study of risk analysis for oil tanker grounding accident response.

원자력발전소의 안전성을 평가하는 확률론적 안전성평가(PSA) 기법 내에서 인간신뢰도분석(HRA： Human Reliability Analysis)은 파악된 사고경위 중 부적절한 인적행위사건에 대한 분석 및 평가를 담당하고 있다. 여러 HRA 전문가들이 제기하고 있는 기존 PSA HRA의 개선점 중 정성적 분석 관점에서 중요하게 고려되는 사항을 정리하면 다음과 같다. 첫째, 운전원의 진단 및 상황판단 또는 의사결정 단계에서의 특정한 오류 유발사항(error producing conditions or error forcing context)을 분석할 수 있는 방법이 필요하며, 둘째, 다양한 인적오류사건의 고려이다.(중략)

옛 속담에 '소 잃고 외양간 고친다'는 말이 있지만, 속담의 의도와는 다르게 때로는 소를 잃고도 더 튼튼한 외양간을 지어야 하는 경우도 있다. 지난 2003년 발생했던 1.25 인터넷 침해사고는 국내 정보통신망의 보호체계에 허점이 드러난 대표적인 사건으로 회자되고 있지만, 당시 경험을 바탕으로 국내 침해사고 대응체계는 예방활동만으로 약 5조 3,000억원의 효과를 거두는 등 한 단계 발전하는 계기를 마련했다. 대규모 침해사고가 발생한 지 5년이 지난 현재, 국내의 침해사고 대응체계는 어떻게 변모되고 또 발전돼 왔는지 살펴보자.

This study selected the Marine Corps camp accident in 2013 as its subject and analyzed it in order to explore the relevance of media framing on discourse on the safety of outdoor experience activities. Data were collected from search sites provided by news coverage data from March 26, 2010 when the sinking of the South Korean Navy corvette Cheonan occurred in South Korea, which had seen a surge in Marine Corps experience camps, to July 21, 2013, a few days after the Marine Corps camp accident. Data about a total of 211 cases 138 cases before the Marine Corps camp accident, and 73 cases after the accident were inductively analyzed. According to the results, news coverages on the Marine Corps camp were largely divided into positive framing that glamorized outdoor experience activities before the accident and negative framing after the accident. To put it concretely, the framing before the accident tended to glamorize outdoor experience activity as the best educational program which helped the participants to enhance their patience and sense of independence through boot camp experience, thereby increasing their self-esteem and arousing their cooperative spirit as members of society. However, after the accident media framing tended to publicize insensitivity to safety. The media framing characterized by dualistic coverage is considered to be an obstacle to the spread of safety culture, which is required in South Korean society. Therefore, media need to maintain more cool-headed and objective attitudes when reporting news.

최근 AI 를 비롯한 데이터 기반의 비즈니스 모델 증가에 따라, 데이터 유출 등의 기업 정보보안 사고가 빈번하게 발생하고 있다. 해당 사고들은 종종 법적 분쟁으로 이어지며, 이는 기업의 막대한 경제적 손실을 초래하며 정보보안 사고를 선제적으로 대비하기 위한 기술적, 관리적 조치 마련을 위한 기업의 관심이 증가하고 있다. 이에 본 연구에서는 최근 들어 급증한 기업의 정보보안 관련 판례를 대상으로 BERTopic, Top2Vec, LDA 를 활용하여 토픽 모델링을 수행하여 산출된 토픽 기반의 기업 정보보안 사고를 유형화하고자 한다. 전통적으로 각각 다른 법적 요소와 판결을 담고 있어, 유사 사건 간의 비교 및 분석이 어려운 판례 데이터의 특징을 반영하여 본 연구에서는 앞서 제시된 3가지의 모델을 각각 적용한다. 이를 통하여 각 모델 수행 결과의 성능 비교를 통하여 기업의 정보보안 사건의 유형화 및 동향을 파악하는 동시에 판례 데이터를 분석하기 위한 최적의 모델을 확인한다.

As IT environment has changed, paths of information security in financial environment which is based on IT have become more diverse and damage caused by information leakage has been more serious. Among security incidents, personal information leakage incident is liable to give the greatest damage. Personal information leakage incident is more serious than any other types of information leakage incidents in that it may lead to secondary damage. The purpose of this study is to find how much personal information leakage incident influences corporate value by analyzing 21 cases of personal information leakage incident for the last 15 years 1,899 listing firm through case research method and inferring investors' response of to personal information leakage incident surveying a change in transaction before and after personal information leakage incident. This study made a quantitative analysis of what influence personal information leakage incident has on outcome of investment by types of investors by classifying types of investors into foreign investors, private investors and institutional investors. This study is significant in that it helps improve awareness of importance of personal information security by providing data that personal information leakage incident can have a significant influence on outcome of investment as well as corporate value in Korea stock market.

The purpose of this paper is to examine the concept of "accident" under the Warsaw system including the Warsaw Convention for the Unification of certain Rules for International Carriage by Air of 1929 and the Montreal Convention of 1999. Most leading case on this subject is Air France v. Saks(470 U.S. 392 (1985)). In the Saks case, it was held that the definition of an accident must be applied flexibly, and most courts have adhered to the definition of accident in Saks case, the application of accident has been less than consistent. However, most cases have held that if the event is usual and expected operation of the aircraft, then no accident has occurred. Courts have also held that where the injury results from passenger's own internal reaction to the usual, normal, and expected operations of the aircraft, it is not caused by an accident. As the Warsaw drafters intended to create a system of liability rules that would cover all hazards of air travel, the carrier should liable for the inherent risks of air travel. It is right in that the carrier is in a better position than the passenger to control the risks during air travel. Most US courts have held that carriers are not liable for one passenger's assault on the other passenger. The interactions between passengers are not part of the normal operations of the aircraft and are therefore not covered by the word "accident" under Art 17 of the Warsaw Convention. It is regretful that the Montreal Convention did not attempt to clarify the concepts of accident in itself. In the light of an emerging tendency to hold the air carrier liable for occurrences that do not exactly go to the operation of the aircraft, it is desirable to regulate that the carrier is liable for an "event" instead of an "accident" in accordance with the Guatemala City protocol.
