  • Recently, CCTV installations are rapidly increasing in the public and private sectors to prevent various crimes. In accordance with the increasing number of CCTVs, video-based abnormal behavior detection in control systems is one of the key technologies for safety. This is because it is difficult for the surveillance personnel who control multiple CCTVs to manually monitor all abnormal behaviors in the video. In order to solve this problem, research to recognize abnormal behavior using deep learning is being actively conducted. In this paper, we propose a model for detecting abnormal behavior based on the deep learning model that is currently widely used. Based on the abnormal behavior video data provided by AI Hub, we performed a comparative experiment to detect anomalous behavior through violence learning and fainting in videos using 2D CNN-LSTM, 3D CNN, and I3D models. We hope that the experimental results of this abnormal behavior learning model will be helpful in developing intelligent CCTV.

  • Objectives: The purpose of this study was to investigate the perception of workplace bullying in the dental hygienists to use them as basic data for improving the organizational relationship of the dental hygienists. Methods: The subjects were 302 dental hygienists that had been working at the dental clinics and dental hospitals. These data were analyzed by SPSS Version 20.0 (IBM Co., Armonk, NY, USA). Factor analysis was used for exploratory and confirmatory data. Independent t-test and one-way ANOVA were used to find out mean differences for verbal violence, improper business, and improper work environment according to characteristics of subjects. Results: Upon the study results, there were statistically significant differences between the verbal violence and working patterns according to the mean differences of the subfactors on subject's characteristics. Also, there were statistically significant differences between the improper work environment and all of subject's characteristics. However, there was no statistically significant differences in the improper business. The factor analysis showed that the Workplace Bullying of the dental hygienists was composed of three elements, namely 'verbal violence', 'improper business,' and 'improper work environment.' The validity of the model examined by a confirmatory factor analysis satisfied most of the relevant requirements. The Cronbach's aplha shows a good reliability. Conclusions: In conclusion, it was proven that dental hygienist's Workplace Bullying measurement tool had high validity and reliability. Furthermore, this study can be used to improve dental hygienists' organizational relationship. Therefore, by identifying the recognition of the dental hygienists, this study can contribute to affect a positive influence in the dental hospitals.

  • Recent incidents of lethal violence in the Rakhine State of Myanmar between the majority Buddhist Rakhine and the Muslim Rohingya have been the source of much concern for the international community. Unlike the past, the killings and incendiary attacks by both communities have intensified to a critical level, proving to be a great liability for the forward-thinking Myanmar government, whose recent transition to civilian rule after a long military one has made it eager to move on. The roots of the conflict trace back to the military regime, who branded the Rohingyas living in Rakhine state as illegal immigrants and refused to confer upon them official recognition as Myanmar citizens. The discord then moved to an ethnic conflict, pitting the Rohingya not merely against the Myanmar government but rather the majority Buddhist Rakhine. The conflict, as it has developed into the present, is an immensely complicated one that simultaneously encompasses ethnic and religious issues, all intertwined together. This study aims to see how the two ethnic groups have come to resort to such violence, despite having lived in each other's presence for many centuries, and why the violence persists. It will attempt to reconcile the fact that Rakhine had historically been a place of convergence for two groups, the Buddhist Rakhine and the Rakhine Muslim(the Rohingya). Based on the argument, this study also seeks to uncover, identify, and understand the Rohingya identity with the extreme arguments exhibited by both sides, and from there, locate the underlying causes of the greater religio-ethnic conflict in Rakhine that has so ravaged the place as of recent.

  • In this paper, we proposed an automatic monitoring system for contact center in order to manage customer's complaint and agent's quality. The proposed system allows more accurate monitoring using emotion recognition and keyword spotting method for neutral/anger voice emotion. The system can provide professional consultation and management for the customer with language violence, such as abuse and sexual harassment. We developed a method of building robust algorithm on heterogeneous speech DB of many unspecified customers. Experimental results confirm the stable and improved performance using real contact center speech data.

  • The purpose of this study was to provide the basic data for establishing school education environment protection measures, on the basis of comparing and analyzing the realities and students' recognition degree of the environment and hygiene around the middle and high schools located in the rural areas. These study data were investigated by the self-administered questionnaires, taking as subject the 805 students in the middle and high schools located rural areas. And the results were as follows: First, as the result of having investigated the distribution degree of harmful environment within the purification zone around schools, it was found out that students responded: within the purification zone around the middle school, there were cartoon rooms (46.2%), electronic game rooms (45.9%), and singing rooms (45.0%). within the purification zone around the high school, there were electronic game rooms (46.3%), singing rooms (42.3%), billiard halls (41.4%), PC rooms (40.1 %), and Soju-room (35.2%). Secondly, as having analyzed student's recognition degree of the harmful environment around the school, it was found out that middle school students responded that sexual utensils-treating shops (3.74 points) were most harmful, and next corrupted bathhouses (3.52 points), and Soju-room (3.47 points), and high school students also responded relating to harmfulness in a similar sequence. Thirdly, in case of students' recognition degree of the harmful environment around the school according to general characteristics, 1) girl students had a higher ratio of recognition that the environment around the school was harmful than boy students (p〈0.001). 2) groups of students whose living standard was high had a higher ratio of recognition that the environment around the school was harmful than groups of students whose living standard was low (p〈0.05). 3) groups of students whose school was located near the park or the residential street had a higher degree of recognition that the environment around the school was harmful than groups of students whose school was located near the factory or the shopping area (p〈0.01). 4) groups of students whose school was located near the park or the residential street had a higher degree of recognition that the environment around the school was harmful than groups of students whose school was located near the amusement area or the shopping area (p〈0.05). Fourthly, 1) relating to the harmful shops where they experienced most highly the behavior of drinking and smoking, middle school students responded that they did so in the electronic game room (22.5%) and high school students did so in the singing room (31.4%), and high school students had a very high experience ratio of drinking and smoking, compared with middle school students (p〈0.001). 2) relating to the harmful shops where they could get in contact with lewd articles, both of middle school students (5.3%) and high school students (8.3%) responded that they could do so in the video room. 3) relating to the harmful shops where they experienced unsound opposite sex acquaintance, both of middle school students (5.8%) and high school students (16.6%) responded that they did so most highly in hotels, and high school students had a remarkably high experience ratio of unsound opposite sex acquaintance, compared with middle school students (p〈0.05). 4) relating to the harmful shops where they experienced violence, middle school students responded that they did so in the electronic game room (14.0%) and then in the singing room (3.7%), and high school students responded that they did so in the electronic game room (9.3%), the nightclub (4.6%), Soju-room (4.1 %), and high school students had a remarkably high experience ratio of violence, compared with middle school students (p〈0.05). 5) relating to the harmful places where they experienced drugs both of middle school students (0.8%) and high school students (2.4%) responded that they did so in the hotels. Fifthly, when going to the harmful shops, students had the experience of being guided and regulated roughly 1 time - 2 times, and middle school students (16.4%) and high school students (16.7%) had almost similar experience ratios of being guided and regulated. Conclusively, there was a limit in controlling the environment and purification zone only by legal regulations and institutional controls, the self-control purification effort for the school and the surrounding environment was required greatly, in order to protect students from harmful environment. In addition, the constant study to establish the educational environment purification measures must be carried out.

  • 본 연구에서는 다중 감시 카메라 환경에서 폭력행위를 감지하기 위한 알고리즘을 제안하는 것을 목표로 한다. 폭력행위를 하나의 감시 카메라에서 인식하는 것을 포함할 뿐만 아니라 다중 감시 카메라 환경에서 사전에 폭력행위를 인식하여 미리 방지한다면 더욱 안전성을 보장하게 되는 것이다. 폭력행위의 사전 징후는 다중카메라가 있는 모든 지역에 스토킹, 두 사람의 장시간 대치상황, 여러 사람의 장시간 대치상황 등으로 생각할 수 있다. 무엇보다도 각 카메라의 영역이 다르므로 한 객체의 이력을 파악하기 위해 카메라 간의 정보제공 및 동일객체 확인이 필수적이다. 따라서 본 논문은 카메라 간의 동일 객체 확인을 위한 알고리즘과 스토킹 행위인식을 위한 멤버함수를 정의한다.

  • In this paper, we propose a real-time drone-based violent protest detection system. Our proposed system uses drones to detect scenes of violent protest in real-time. The important problem is that the victims and violent actions have to be manually searched in videos when the evidence has been collected. Firstly, we focused to solve the limitations of existing collecting evidence devices by using drone to collect evidence live and upload in AWS(Amazon Web Service)[1]. Secondly, we built a Deep Learning based violence detection model from the videos using Yolov3 Feature Pyramid Network for human activity recognition, in order to detect three types of violent action. The built model classifies people with possession of gun, swinging pipe, and violent activity with the accuracy of 92, 91 and 80.5% respectively. This system is expected to significantly save time and human resource of the existing collecting evidence.

  • The definition of Crime Indictable Upon Complaint (CIC) is crimes which can be prosecuted only with complaints from the victim or his/her direct parents. Sex crimes are the representative examples, rapes and indecent assaults. According to the research referenced in this paper, 74% of sex crimes which had been penalized based on Republic of Korea (ROK) Criminal Code amounts rape and indecent assault are CIC. However, only 20% of perpetrators were confined, and the rest received non-confinement or non-prosecution determination. The review of criminal history checks reveals that 67% of the perpetrators had criminal histories and 39% of them had more than three documented offenses. The CIC was established in order to protect the victim's rights and dignity, respecting the victim's opinion regarding the incident. All kinds of sex crimes then should have been the CIC, but those crimes such as Injury Resulting from Rape, Special Rape, Rape by Special Modus Operandi, Sexual Assault among Relatives and Domestic Violence which have to guarantee the opinion of the victims are prescribed as non-CIC. We therefore conclude that the CIC should be abolished. The abolition of CIC will play an important role in crime prevention because severe penalties for sex crimes will be imposed on the perpetrators. In addition, it will help the sex crime victims retrieve their dignity by spreading recognition widely through the community that sexual assault is not only a social assault but an infringement against human rights.
