본 논문은 4차산업이 발달함에 따라 일반인들도 쉽게 인공지능과 결합한 CCTV를 구축할 수 있는 것을 목표로 하며, 더 나아가 1급보안시설인 항만에서 자주 발생하는 입국자 월담, 행방불명들을 인공지능 CCTV로 감시하여 보다 쉽게 잡고 인력감소로 경제적 이익을 도모할 수 있다.

Intelligent video analysis systems require techniques which can predict accidents and provide alarms to the monitoring personnel. In this paper, we present an abnormal behavior analysis technique based on adaptive background generation. More specifically, abnormal behaviors include fence climbing, abandoned objects, fainting persons, and loitering persons. The proposed video analysis system consists of (i) background generation and (ii) abnormal behavior analysis modules. For robust background generation, the proposed system updates static regions by detecting motion changes at each frame. In addition, noise and shadow removal steps are also were added to improve the accuracy of the object detection. The abnormal behavior analysis module extracts object information, such as centroid, silhouette, size, and trajectory. As the result of the behavior analysis function objects' behavior is configured and analyzed based on the a priori specified scenarios, such as fence climbing, abandoning objects, fainting, and loitering. In the experimental results, the proposed system was able to detect the moving object and analyze the abnormal behavior in complex environments.

The author conducted a records research named 'daily life and records.' The purpose of the research was to find an archive, if possible, that would be effective in promoting exchange and cooperation among people in their daily lives, and to distinguish what type of archive it would be, as well as how to let it naturally take place in their ordinary lives. For 4 months (August-December 2019) with 100 college students in their 20s, trial and error were repeated. There was no separate laboratory for the research, and it used regular school hours at universities. Although it is true that there was a control through power by the college system, the plot was centered on the sunshine policy. To human being there is a voluntary and positive attitude. If anyone begins to take this attitude it is difficult to stop such action. Through emotional support, this voluntary action was encouraged to take root. The experiment was an attempt to doubt the obvious, and to search for something new. From afar, this may seem irrelevant to archives. However, for the author who is a professional archivist, it was a time of records through control by Records principles. By organizing into a form of story, its archival implications are observed.

The statistics of committing suicide in S. Korea is ranked in top with serious attempts of falling among OECD countries since 2003. The rates is slightly dropped by 5 percent point, nevertheless the falling is still high for the age of over 10 years old and this matter must be solved. Most of the case of suicides are the falling based on a trend view of falling which is serious matter and cannot be solved easily for both domestic and foreign countries. For example, the steel net of falling prevent was installed in the Golden Gate Bridge costed by 200 million-dollar. In New Zealand, the steel net of falling prevention had been removed and re-installed beccause of the high suicide rates. Canada and Australia also surrounded the bridge with steel fences to prevent suicide without consideration of the beauty of bridge. Therefore, this paper suggested a comparison study on both falling prevention systems in all countries and patent technologies. Also, it covers the blocking skills of approach in both security and limited area. This paper suggested the technical Rollinder system equipped with the mechanical apprentice to prevent effectively the falling sucides and wall passing. Before the installation of Rollinder System by 2016, there were 33 person who tried to fall in the river in Machang Bridge. However, the number of the committing suicides were dramatically reduced to zero after the installation of the system.
