  • The demand of violence detection techniques using a video analysis to help prevent crimes is increasing recently. Many researchers have studied vision based behavior recognition but, violent behavior analysis techniques usually focus on violent scenes in television and movie content. Many methods previously published usually used both a color(e.g., skin and blood) and motion information for detecting violent scenes because violences usually involve blood scenes in movies. However, color information (e.g., blood scenes) may not be useful cues for violence detection in surveillance videos, because they are rarely taken in real world situations. In this paper, we propose a method of violent behavior detection in surveillance videos using motion vectors such as flow vector magnitudes and changes in direction except the color information. In order to evaluate the proposed algorithm, we test both USI dataset and various real world surveillance videos from YouTube.

  • 기억 인출 단서는 학습을 통해 장기기억 공간에 저장된 정보를 인출하는 과정에서 중요하며, 서로 다른 종류의 기억 인출 단서에 따른 기억 인출 결과 및 이에 대한 인지 학습적 특성 규명은 교육, 범죄 수사, 그리고 인간의 뇌 기능을 모방한 기계학습 연구 등에서 중요하게 다루어져야 할 문제이다. 본 논문에서는 비디오 데이터를 이용하여 학습한 내용을 인출하는 과정에서 텍스트와 이미지가 각각 인출 단서로서 기억인출 결과에 미치는 영향을 분석하고, 기억 정보 및 시각 정보 처리와 관련된 뇌 영역에서의 뇌전도 분석을 이용하여 이를 해석하였다. 실험 결과를 통해 기억 인출을 위해 이미지-텍스트를 제시할 경우 전전두엽의 기억인출 관련 부위와 시각 피질이 위치한 후두엽의 인터랙션이 높게 이루어지면서 암묵적인 시각적기억 표상의 인출이 발생하는 것을 알 수 있었다.

  • Hwaseong serial murders are not now having any significant concern either with Hwaseong City or Dongtan New Town, a region in Hwaseong City, both spatial and temporal manners. However, despite that, people have come to see Hwaseong City with negative ideas as the mass media drove the people to do so. In this study, how films and newspaper articles have created those negative images of Hwaseong City was investigated and afterwards, residents and students living in Dongtan New Town had interviews on what they think about the negative regional images. The study, then, worked on a mental map and others based on what it learned from the interviews. Regional identity confusion is now being discovered out of the people's resistance against the negative images of the city and through such research process described before, the study discussed this regional identity confusion caused by living as residents in Hwaseong and living as residents in Dongtan New Town. In addition, the study revealed sense of place of Dongtan New Town and aspects of the regional identity confusion with this Dongtan New Town growing both with symbolic meanings as a place of murders, an awful crime, and spatial meanings as another place of dynamic developments and improvements.

  • Biographical information about people is usually collected and provided by a company or an institute which has a specific standard to select people for service. Recently, user oriented contents service like Wikipedia has started biographical information service, Wikipedia Biography Portal, in which users select people and freely describe about them. This study collected 500 biographical data from three categories of Wikipedia biography portal such as criminals, faculty, and directors. The contents of data from each category were analyzed with the word frequency and the divergence indicator to identify the characteristics of each category. As a result, divergency indicator is effective to represent the differential factors of each category. This study provides word clouds of top 100 word with divergence indicator and top 100 common words of three categories with word frequency as a guide for users to write about a person in these categories and for editors to accept and monitor the biography from users.

  • As for the various pathological phenomena of the society which is getting worse without any improvement, the film paints the phenomenon nakedly with the cold and cynical gaze on the basis of realism. These attempts originated in the Chinese art world, and they cynically sketched a Chinese society that lost hope after 6·4. The cynicism of the art world contains meanings such as instruction, meanness, passion, indifference, and mockery. In particular, the distrust of the social system after 6·4 and the collapse of the Soviet and Eastern European socialist nations gave the Chinese people a skeptical view of socialism. This situation of the times has a cynical viewpoint to face as it is instead of prudent criticism. This cynical view was embraced by filmmakers who were not silent on The pathological phenomenon of society, and they were directed to films. is a film about the love, separation, suicide, frustration and reconciliation of youth in the era of identity confusion after 6·4. The characters in the film did not mention a single word about the state power that made them do it. based on the characteristics of women in northeast China and the murder that occurred around a woman with a beauty that was not like a laundry employee. Centered around the unresolved slice murder case, expressed human moral ambiguity that does not distinguish good fortune from human instinct for struggle for survival, and portrayed the scenery of a very cold northeast small city. But it does not show any criticism of the crime. Based on the true story of the 2000s, the portrays the uncomfortable aspects of China that established Chinese socialism. A film composed of four short episodes conveys the destiny set by God.

  • Since mechanical security systems are mostly composed of electronic, information and communication devices, they have effects in the aspects of overall social environment and crime-oriented environment. Also, the importance is increasing for wireless recognition of RFID and tracing function, which will be usefully utilized in controlling the incomings and outgoings of people/vehicles or allowance, surveillance and control. This is resulting from the increase in the care for the elderly according to the overall social environment, namely, the aging society, and the number of women entering, as well as the increase in the number of heinous crimes. The purpose of this study is to examine the theoretical considerations on ubiquitous sensor network and present a direction for securities companies for their development by focusing on the technological and application areas. To present strategies of response to a new environment for security companies, First, a diversification strategy is needed for security companies. The survival of only high level of security companies in accordance with the principle of liberal market competition will bring forth qualitative growth and competitiveness of security market. Second, active promotion by security companies is needed. It is no exaggeration to say that we are living in the modern society in the sea of advertisements and propaganda. The promotional activities that emphasize the areas of activity or importance of security need to be actively carried out using the mass media to change the aware of people regarding security companies, and they need to come up with a plan to simultaneously carry out the promotional activities that emphasize the public aspect of security by well utilizing the recent trend that the activities of security agents are being used as a topic in movies or TV dramas. Third, technically complementary establishment of ubiquitous sensor network and electronic tag is needed. Since they are used in mobile electronic tag services such as U-Home and U-Health Care, they are used throughout our lives by forming electronic tag environment within safe ubiquitous sensor network based on the existing privacy guideline for the support of mobile electronic tag terminal commercialization, reduction in communication and information usage costs, continuous technical development and strengthening of privacy protection, and the system of cooperation of academic-industrial-research needs to be established among the academic world and private research institutes for these parts.
