Swift and appropriate responses in emergency situations like objects falling on the road can bring convenience to road users and effectively reduces secondary traffic accidents. In Korea, current intelligent transportation system (ITS)-based detection systems for emergency road situations mainly rely on loop detectors and CCTV cameras, which only capture road data within detection range of the equipment. Therefore, a new detection method is needed to identify emergency situations in spatially shaded areas that existing ITS detection systems cannot reach. In this study, we propose a ResNet-based algorithm that detects and classifies emergency situations from vehicle camera footage. We collected front-view driving videos recorded on Korean highways, labeling each video by defining the type of emergency, and training the proposed algorithm with the data.

Recently, the awareness of the domestic information security is very higher due to cyber war and hacking incidents. Yet, the information security professional is very scarce situation. In these circumstances are increasing of a opening the information security related departments of the domestic universities. And the Educational institutions are developed various curriculums. However, the domestic information security curriculum is different depending on the university or department. And there tends to be concentrated on the practical education rather than theoretical education. Therefore, in this paper will be analyzed to the Information security curriculum situation of the domestic Information Security related universities. This is expected to be utilized in a systematic curriculum development of the domestic information security education in a future.

최근 통계자료에 의하면 국내 제방붕괴 유형 중 11.5%가 제체 불안정에 의한 붕괴로 보고되고 있다. 홍수시 노후화된 제방이 붕괴하여 발생하는 인명 및 재산피해는 점차 증가하고 있는 상황이어서, 이에 대한 제방 시설물의 보강 및 안전관리 대책이 필요한 상황이다. 하천시설물 주변의 흐름특성에 의하여 세굴이 발생할 수 있는 지점에는 보호공을 설치하여 시설물의 안정성을 확보하도록 하천설계기준 해설(2009)에서 제안하고 있다. 그러나 구조물을 보완하는 보호공의 공종 및 규격 등을 설계하기 위한 세부적인 설계지침이 미흡하여 외국의 연구 또는 설계사례를 참고하여 국내 하천에 적용하고 있는 상황이다. 해외의 연구사례를 살펴보면, 설계공식에 적용된 설계인자인 유속 및 수심 등을 1차원 단면평균값을 활용하는 경우가 많아서 복잡한 하천의 흐름특성을 반영하기에 미흡한 상황이다. 본 연구에서는 국내 하천해석에서 주로 활용되고 있는 수치모형을 이용하여 실험수로의 흐름을 재현하고 수리실험을 통하여 관측한 유속 및 수위분포 결과와 비교하였다. 2차원 수치모형으로는 RMA2, CCHE2D, FLUMEN 등의 상용모형과 최근 연구가 활발히 진행되고 있는 Approximate Riemann 기법을 적용하여 개발된 유한체적모형을 적용하였다. 제방 부근에서 형성되는 흐름을 상세하게 모의하기 위하여 국내 하천시설물 설계에서 많이 활용되고 있는 FLOW-3D 모형을 적용하여 3차원 모의결과와 수리실험결과를 비교하였다. 수리실험에서 관측된 사석호안공의 이탈시 흐름현상을 재현하여 호안공 이탈에 영향을 미치는 국부유속 및 전단응력을 산정하여 호안설계에 적합한 설계인자를 분석하였다. 연구결과를 활용하여 사석호안공 설계 기법에 적용되는 수치모형을 통하여 산정되는 설계인자의 정확성을 향상시킴으로써, 정량적이고 합리적인 사석호안공 설계기법개발에 도움이 될 것으로 판단된다.

IT분야의 벤처기업 창업 활성화의 일환으로 정보통신부는 '98년도부터 투자 사업을 통해 IT전문투자조합에 출자해 오고 있다. 이글에서는 정보통신부가 출자한 IT전문투자조합의 운영 현황을 구체적으로 살펴보고, 최근까지 IT전문투자 조합을 통해 이루어진 투자 내역을 토대로 지난 4년간 국내 벤처캐피탈의 IT부문 벤처 투자 동향을 분석해 보았다. 이번글은 아직 벤처캐피탈 투자에 대한 정보가 부족한 상황에서 IT부분을 중심으로 과거 국내 밴처 캐피탈의 투자에 대한 분석을 수행했다는 점에서 의의를 지닌다 이글을 통해 향후 IT전문 투자조합 및 국내 벤처캐피탈의 투자조합 운영에 있어 개선점을 제시해 국내 벤처캐피탈의 선진화에 기여하고자 한다.

This study sought to find out the status of medical libraries in Korea that provide information services related to the Covid-19 situation, and how the librarian's perception of the Covid-19 situation, the main body of the library's information provision, affects the provision of related information services. For this purpose, we checked the website for Covid-19 information service. In order to understand the degree of awareness of Covid-19, Grunig's Situational Theory was applied to classify four types of librarians according to the degree of problem recognition, constraint recognition, and involvement recognition, and to analyze how the three perceptions affect Covid-19 related information services. As a result, only 25 out of 144 korean medical libraries provided information services related to Covid-19. The librarian, the main agent of the library's information provision, found that the problem recognition and involvement recognition in the Covid-19 situation were high, constraint recognition were low, and the level of information service was very active. And only constraint recognition has been shown to have a significant impact on providing Covid-19 related information services. Further research when future sources are available and follow-up research on how librarians' perceptions affect library operations are also proposed.

The need for the development of practical manuals for responding to disasters in public libraries has emerged after COVID-19 was confirmed in Korea in January 2020. The library is a social organization directed affected by COVID-19. Therefore, a reasonable and consistent disaster response manual should be developed and used as a guideline for responding to disasters at the library sites. This study aims to derive implications by examining the current situation of public library manuals for both domestic and international. Furthermore, the responses of overseas libraries experiencing major disasters were analyzed and issued to reflect the current domestic situation. As a result of the study, it was suggested that the library's role as a social organization for disaster response should be enhanced, and that disaster experience needs to be implemented, as guidelines, toolkits, and archive.

In 2020, the novel coronavirus disease (COVID-19) struck the world. This study examined Korean public libraries' responses during the COVID-19 pandemic to determine their working practices, service patterns, applied strategies, and roles played. The study administered an online survey to 317 public librarians in South Korea. The results indicated that librarians reported significant transitions regarding the services provided. However, only 15.5% of the survey respondents reported that they had experienced trainings/workshops for library staff members. Survey participants also identified challenges such as the limitations of non-face-to-face services, complaints from library patrons, and overwork due to epidemic prevention. When it comes to the expected roles of public libraries in upcoming disasters, the study contends that information providers, who guide the public through various information resources, would play the most critical role. An analysis of a few open-ended questions' answers proliferated the highlighted findings. Based on the key findings, this paper also discussed implications for information professionals and future research.
