  • Due to the recent developments in computer vision technology, complex actions can be recognized with reasonable accuracy in smart cities. In contrast, violence recognition such as events related to fight and knife, has gained less attention. The capability of visual surveillance can be used for detecting fight in streets or in prison centers. In this paper, we proposed a deep learning-based violence recognition method for surveillance cameras. A convolutional neural network (CNN) model is trained and fine-tuned on available benchmark datasets of fights and knives for violence recognition. When an abnormal event is detected, an alarm can be sent to the nearest police station to take immediate action. Moreover, when the probabilities of fight and knife classes are predicted very low, this situation is considered as normal situation. The experimental results of the proposed method outperformed other state-of-the-art CNN models with high margin by achieving maximum 99.21% accuracy.

  • With the increased frequency of crime such as assaults and sexual violence, the reliance on CCTV in arresting criminals has increased as well. However, CCTV, which should be monitored by human labor force at all times, has limits in terms of budget and man-power. Thereby, the interest in intelligent security system is growing nowadays. Expanding the techniques of an objects behavior recognition in previous studies, we propose a system to detect forms of violence between 2~3 objects from images obtained in CCTV. It perceives by detecting the object with the difference operation and the morphology of the background image. The determinant criteria to define violent behaviors are suggested. Moreover, provable decision metric values through measurements of the number of violent condition are derived. As a result of the experiments with the threshold values, showed more than 80% recognition success rate. A future research for abnormal behaviors recognition system in a crowded circumstance remains to be developed.

  • The government has defined domestic violence as one of the four major social evils and tried to prepare laws and systems to prevent it. Nevertheless, domestic violence has emerged as a serious social issue, and compare to the number of domestic violence cases that are constantly increasing, the report rate of domestic violence is significantly lower. This suggests the need to improve citizens' perception of domestic violence as the issue to solve it together in society, not as a private matter at home. Most of existing contents for preventing domestic violence and improving awareness are simple viewing forms of video contents, which have little effect on recognition. We aim to confirm the possibility of improving social awareness about domestic violence by producing Virtual Reality (VR) contents that have great features of user's immersion and empathy. In this VR content, the user can interact with various objects in the virtual reality of domestic violence and directly or indirectly experience the victim's position. Users who view the violent environment from the victim's point of view can have a subjective empathy for the problem, which is expected to induce more active awareness about domestic violence.

From Law/Superego to Love: Law, Violence, and the Possibility of Love in Herman Melville's Billy Budd, Sailor (법/초자아에서 사랑으로 -허먼 멜빌의 『빌리 버드』에 나타나는 법, 폭력, 그리고 사랑의 가능성)

  • This essay aims to explore Herman Melville's recognition and resolution of the vicious link between law and violence in his posthumous Billy Budd, Sailor (1924). In order to investigate the issues, this essay refers to Freud, Benjamin, Derrida, Lacan, and Žižek, all perceptive to the uncanny affinity of law and violence. Especially, Žižek's arguments of "superego" as an embodiment of cruel and destructive violence supplementing the official law and of "love" as an ethical possibility beyond the limit of the problematic law are introduced in this study to make Melville's reflection of the inseparableness between law and violence much clearer. John Claggart and Captain Vere embody the legal (superegoic) violence. Claggart even procurs secret enjoyment, in the name of maintaining positive law. Billy Budd discloses another violence defending his justness according to natural law. However, Melville suggests the possibility of suspending the problematic tie of law/violence through "love," as portrayed at the last part of the story. The two final words from Billy and Vere, as a sort of delayed dialogue between them after the event of their secret interview before Billy's hanging, suggest that they finally distance from the obscene nightly law of superego-respectively from outward punitiveness toward Vere and from inward punishment for Vere's excessive enforcement of Billy's hanging-and identify each other's lack as their own. Their love implicated in the last words is for the real other-in Lacan's sense-who discloses the constitutive lack or incompleteness of beings and aporia of the law. This essay's examination of Melville's representations about the superegoic violence as the (im-)possible condition of law and the possibility of withdrawing from it would help us recognize Billy Budd, Sailor as the author's own last word for the possible vision of love cutting the vicious knot of law/violence.

  • The purpose of this study was to analyze the differences in dating violence perception of dating violence perception of university students. As a research tool, CTS2 was used as a measure of dating violence, a measure developed by Kim(1999) was used, and a measure of dating violence by Jeong(2013) was used. Data analysis was performed using independent sample t-test and multi-variate analyses. The results are summarized as follows. First, female students showed higher differences in total violence against violence and psychological violence than boys, while boys showed higher physical violence than girls. Health majors were significantly higher in total dating violence and psychological violence than students in humanities and social sciences. There was no significant difference in dating violence offenses with or without sexual experience. Only psychological violence showed an interaction effect between gender and sex experience. Second, female students were significantly higher than male students with significant differences in recognition and sub-factors. Health majors were significantly higher in both date violence perception and lower factors than humanities and social sciences. Students without sexual experience perceived overall dating violence more than students with sexual, physical and cyber violence being significantly higher.

  • Purpose: This study was to explore health experiences of victims of sexual violence reflected in Newman's health as expanding consciousness theory. Method: Nurse as researcher use Newman's praxis methodology because it is good for showing the process of interaction between researcher and sexual abuse victims. Results: The significant characteristics of early health experiences during negative situations were a lot of suffering. However, after a turning point in health experience, the health experiences of most of the participants evolved as expanding consciousness. Conclusion: The study has provided support for Newman's theory of health. Most of the participants recognised meanings in their patterns and trustful caring relationships with the nurse as researcher. Pattern recognition as a nursing practice was a meaningful transforming process in the participant-nurse partnership.
