담배를 끊는 사람들의 마음은 애절하다. 물론 애절함이 더 욱 크기에 완전한 '금연'에 도달하는 사람 또한 드물다. 매년 연말이 되면, 새해 꼭 지켜야 할 자신과의 약속 몇 가지를 품게 된다. 아마 흡연자들의 가장 큰 목표가 금연일 것이다. 하지만 지키기 가장 어려운 것 또한 금연이다. 매해 연초, 담배 판매량이 줄었다가도 이내 제자리로 돌아오는 것은 그만큼 금연이 힘들다는 방증이다. TV 뉴스에서는 흡연의 폐해를 수시로 보도하고, 대표적인 난치병인 각종 암을 소개할 때도 '흡연자가 비흡연자보다 발생률이 몇 배 더 높다'라는 멘트를 귀에 딱지 앉을 만큼 자주 듣게 된다. 이처럼 담배, 즉 흡연의 위험성을 알면서도 사람들은 왜 죽음(?)을 각오하면서 담배를 피우는 걸까?

The development in smartphone technology has brought convenience to the life of the mankind, but an excessive use of smartphones sometimes causes various accidents. This research tried to propose an application service 'Smombie Safe Go' UI(User Interface) that allows the prevention of such accident while using smartphones when walking. For this, after research and user observations, produced walker journey maps and derived necessary main functions needed for safety, and the result showed that transparent interface, obstacle location alert, warning of dangers functions were necessary. To make the contents of the service more detailed, hazardous situations faced during smartphone use when walking were classified into 3 situations : 1. Obstacle appearing in front, 2. traffic lights on crosswalks 3. No traffic lights on crosswalks. Scenarios by hazardous situation were written, and the flow and UI of the app service that warns its users in each situation of hazards were designed. it is predicted that 'Smombie Safe Go' may be possible to be utilized as an app service that provides a safe walking experience for not only regular pedestrians but also the blind population.

산업현장의 안전을 이룩하는데 화재 및 폭발 사고의 방지는 매우 중요하다. 또한 우리 제품의 수출활성화를 위해서도 국제적으로 표준화되고 인정받는 방폭전기기기의 규격 및 성능보장이 필수적인 요건으로 대두되고 있다. 이를 위해 정부차원에서도 본격적으로 법규를 개정하고 관련규격을 제정하는 등의 제도적 뒷받침을 시작하였으며, 그 일환으로서 폭발위험지역에서의 방폭형 전기기기의 사용을 의무화하고 이들 기기의 성능검정을 실시하게 되었다. 그러나 우리나라의 전기기기 방폭기술은 아직 초기단계에 있는 만큼 관련업체, 성능 검정기관 및 정부기관의 적극적인 설비투자와 학계 및 연구기관 등의 적극적이고 지속적인 연구개발을 통하여 이를 본격적인 궤도에 올려 놓아야 할 것이다. 최근 매스콤의 잦은 보도를 통하여 알 수 있듯이 재산에 막대한 손실을 가져오므로 철저한 사전 대비에 의하여 예방토록 하여야 할 것이다. 이를 위해 위험지역에서 사용하는 전기기기의 방폭화는 필수적이다.

언론보도에 따르면 우리나라 어린이들의 사망률이 인구 10만명당 25.6명으로 OECD회원국 가운데 가장 높은 것으로 나타나고 있다. 모든 위험상황으로부터 최우선적으로 보호되어야 할 대상인 어린이들이 우리 사회에서는 상당한 위험에 노출되어 있는 것이 현실이다. 지난 30년간의 급속한 산업화로 인해 물질의 풍요는 누렸지만 그 이면에 나타난 각종 안전사고는 점차 증가 추세이며 더욱 늘어날 것으로 예상되고 있다. 어린이의 귀중한 생명과 재산을 보호하기 위해서는 무엇보다도 어릴적부터 철저한 안전교육을 통한 안전 습관화와 함께 범 국가적인 차원의 안전대책이 마련되어야 할 것이다. 이에 우리나라도 올해를 어린이 안전 원년의 해로 정하여 각종 안전대책을 마련하고 있으며 학교안전 교육의 중요성이 부각되면서 안전교육을 위한 프로그램의 개발 보급이 요구되고 있다. 이전의 안전교육용 프로그램이 한국산업안전공단, 교통안전공단 둥 주로 외부기관에 의해 제작되어 초등학교 현장에 직접 투입하기에는 적절치 않아 초등학생들의 발달단계와 교육과정 분석을 통해 초등학교 학생들의 수준에 알맞은 내용으로 재구성하여 본 프로그램을 설계하게 되었다.

This paper describes the system for detecting vehicles in the rear and rear-side that access between sidewalk and bus stopped to city road at day by computer vision-based method. This system informs appearance of vehicles to bus driver and passenger for the safety of a bus passenger getting off. The camera mounted on the top portion of the bus exit door gets the rear and rear-side image of the bus whenever a bus stops at the stop. The system sets search area between bus and sidewalk from this image and detects a vehicle by using change of image and sobel filtering in this area. From a central point of the vehicle detected, we can find out the distance, speed and direction by its location, width and length. It alarms the driver and passengers when it's judged that dangerous situation for the passenger getting off happens. This experiment results in a detection rate more than 87% in driving by bus on the road.

This paper aims to compare and analyze the major keywords according to the political orientation of progressive and conservative newspapers by utilizing the big data of the four major domestic daily newspapers related to COVID-19, which has entered a long-term war. To this end, 93,917 news reports from Jan. 20 to Sept. 15, 2020 were divided into four stages and the major keywords of the four newspapers were implemented and analyzed in WordCloud. According to the analysis, the conservative newspaper focused on the government's response, criticism, and China's responsibility by mentioning the keywords "government," "president," "state of affairs" and "mask" more than the progressive newspaper, while the progressive newspaper uses keywords that emphasize the seriousness of the disease and the occurrence of a dangerous situation. The Chosun Ilbo found that the use of various keywords during the massive outbreak of collective infections (2.18-5.15), and that the JoongAng Ilbo used keywords criticizing government policies in relation to reports of infectious diseases such as COVID-19, but also used keywords that emphasize the seriousness of diseases used by progressive newspapers and the occurrence of dangerous situations.

Purpose: Most of cybersecurity breaches occur in SMEs. As the existing cybersecurity framework and certification system are mainly focused on financial and large companies, it is difficult for SMEs to utilize it due to lack of cybersecurity budget and manpower. So it is necessary to come up with measures to allow SMEs to voluntarily manage cyber risks. Method: After reviewing Cybersecurity market, cybersecurity items of financial institutions, cybersecurity framework comparison and cybersecurity incidents reported in the media, the criticality of cybersecurity items was analyzed through AHP analysis. And cybersecurity items of non-life insurers were also investigated and made a comparison between them. Result: Cyber risk management methods for SMEs were proposed for 20 major causes of cyber accidents. Conclusion: We hope that the cybersecurity risk assessment measures of SMEs in Korea will help them assess their risks when they sign up for cyber insurance, and that cyber risk assessment also needs to be linked to ERM standardization.

The study aims to find the characteristics of children's crossing behavior on crosswalk in school zones. It considers accident occurrence and physical form of school zones. Seven elementary school zones were investigated. Using data collected by field observation and video recording, statistical analysis, CHAID algorithm analysis, and pattern analysis were performed. As a result, it was found that children's waiting, attention and distraction were related to the accident occurrence. While 69.1% children showed waiting-before-crossing behavior in low-accident occurrence crosswalk, 83.6% children showed non waiting-before-crossing behavior in high-accident occurrence crosswalk. Moreover, the ratio of waiting, attention behavior was found to be higher when the width of the crosswalk was wide and the distance from the school's entrance to the crosswalk was long. These research findings showed that children's behavior-oriented approach was required to improve safety in school zone.

Pedestrian deaths account for a high percentage of deaths in traffic accidents in Korea, raising interest in pedestrian safety policy. However, since the walk signal time is applied based on the length of the crosswalk without considering the walker and the signal cycle, the walk waiting time is relatively longer than the crosswalk, causing pedestrian jaywalking. In this study, due to an unreasonable signal time plan during a road crossing where a signal is installed, the pedestrian's walk signal was given twice a cycle of crossings, and the operational and safety effects of the signal system were quantitatively and qualitatively analyzed, and the operational effects of the signal interval and jaywalking rate were assessed by different signal intervals. The results showed that jaywalking and waiting time decreased, and the shorter the interval between the application of the walk signal time, the less jaywalking is analyzed. However, there is a risk of vehicle conflict due to pedestrian exposure, and measures for expanding safety for operation were proposed.

In this paper, we propose an on-line mechanism that simultaneously detects cracks and profiling pavement blocks to detect the displacement of ground surface adjacent to the excavation in the urban area. The proposed method utilizes a 2D laser to profile the information about pavement blocks including the depth and distance among them. In particular, it is designed to enable the detection of cracks and portholes at runtime. For the experiment, real data was collected through Gocator, and trainng was carried out using Faster R-CNN. The performance evaluation shows that our detection precision and recall are more than 90% and the pavement blocks are profiled at the same time. Our proposed mechanism can be used for monitoring management to quantitatively detect the level of excavation risk before a large-scale ground collapse occurs.
