현재 엘리베이터 내에서는 수많은 범죄들이 발생하고 있으며, 그 대담성 또한 날로 증가하고 있다. 본 논문에서는 불법한 유형력의 행사인 폭행과 이러한 폭행에 동반되는 물리적인 행사인 폭력에 대하여 의미를 알아본다. 그리고 엘리베이터 내에서 발생하는 폭행과 폭력을 추출하는 방법을 제시하도록 한다. 장면 전환 검출 방법 중의 하나인 컬러히스토그램 기법을 사용하여 키프레임을 추출한다. 추출된 키 프레임들은 영상 포렌식에서 범죄 현장을 담은 장면의 증거자료인 프레임이 된다.

유치장은 피의자나 경범죄를 지은 사람 등을 잠시 수감하는 곳으로, 질서가 유지되어야 하는 공간이지만 수감자 간의 폭행과 같은 사건이 발생하는 문제가 있다. 따라서 유치장 내 폭행 사건의 신속한 대응은 질서를 유지하기 위한 핵심 과제 중 하나이다. 이 문제를 해결하기 위해 본 연구에서는 수감자들의 객체를 통합 바운딩박스의 변화율을 통해 격렬한 움직임을 포착하고 스켈레톤 키-포인트의 속도를 측정해 폭행인지 판단한다. 연구 결과, 제안하는 알고리즘의 정확도는 91%로 실시간 폭행 탐지에 유의미하다는 것을 확인할 수 있다.

Object：The purpose of this study was to investigate frequency and risk factor of violence toward parents seen in adolescents. We also want to apply this data toward developing a prevention program for adolescent violence. Method：A total of 1,345 students from 5 middle schools in Seoul, participated in this study：675 males, 670 females. We administered self-reporting questionnaire including violence toward parents, exposure to violence, family history of alcoholism, substance abuse of adolescetnt and dermographic data etc. Result：The frequency of boys’ violence toward parent was 2.8%, which was significantly higher than girls’(p<0.001). The frequency of violence toward the father was higher than the mother. The risk factors for violence toward parents were sex, parental alcohol problem, adolescent alcohol-smoking-drug problem, exposure to violence at home in the last year and exposure to violence in the life(p<0.0001). The grade, punishment, socioeconomic status, educational level of parent were not significantly related to violence toward parents. Conclusion：These suggest that adolescent violence toward parents is not rare problem any more and preventive intervention is needed for high-risk groups, that is related with experience domestic violence, substance abuse, alcoholic parent.

In this paper, we see the means for the assault, the type of unlawful exercise of power. Also, we see the violence, the physical exercise accompanying with assault. Now, it has caused numerous crimes in elevators. This paper is to present a way to extract the violence and assault that occurred in elevators. Key frame was extract by color histogram method, one of the ways to scene change detection techniques. Extracted key frames are key frames of a scene containing a forensic crime scene video. Also, the key frames of the scene should be submitted to the forensic evidence.

통합관제센터에서 제공하는 서비스 중에서 주정차 단속, 쓰레기 투기방지 등 일차적인 영상감시 외의 어린이 유괴, 폭행 등의 복합적인 상황에 대한 지능형 영상감시를 위하여 본 논문에서는 폭행이라는 특정 상황을 가정하고 이에 대한 상황 발생 시나리오 및 상황 코드를 정의하여 실제 시스템에 도입할 수 있는 방안을 제안하였다.

Assault said to contact the opponent's body with the power to superior opponent. In other words, it is the act of hitting an opponent with the fist. In this paper, the violence and assaults that occur in elevators extracted using a color histogram of scene change detection technique.

There have been various discussions to prevent violence to 119 emergency medical technicians, and the aims of the were as follow ; first, the staff dispatched to the scene should be reinforced so that the patients committing violent acts can be subdued. Secondly, self-defense devices should be provided to 119 emergency medical technicians so that they can use them in a dangerous situation and escape from it. And finally, 119 emergency medical technicians should be allowed to refuse to transport the patients when they or their guardians do violence to them in order to prevent potential violent cases. When countermeasures after violence is committed, it is important to secure evidence and determine strongly to bring charges to the offenders rather than agree to overlook the violence in order to correct them right. It is necessary to introduce a support program to help the victim technicians concentrate on their physical and mental treatment. Violence to 119 EMT should be punished so that the society will think it is natural to punish such offenders. In a safer environment, 119 EMT can perform their duties and it is very important to draw this consensus.

The attack refers to the act deliberately to stimulate an abomination to the people. Of violence, such as physical aggression, direct physical forcing. Assault said to contact the opponent's body with the power to superior opponent. In other words, it is the act of hitting an opponent with the fist. In this paper, the violence and assaults that occur in elevators extracted using a color histogram of scene change detection technique.

본 논문에서는 엘리베이터 내에서의 폭행 장면을 효율적으로 추출하기 위해 컬러-$x^2$ 히스토그램을 이용하였다. 컬러-$x^2$ 히스토그램은 컬러히스토그램의 장점과 $x^2$ 히스토그램의 장점을 결합한 추출 방법이다. 또한 기존의 컬러-$x^2$ 히스토그램을 이용하여 키 프레임을 찾아내기 위해 임계값을 찾아낼 때, 실제 폭행 장면 인지 아닌지를 판별하는 확률을 높이기 위해 20개의 샘플영상을 이용하여 통계적인 판단을 이용하였다.
