Recently, as the demand for Generative Artificial Intelligence (AI) and artificial intelligence has increased, the seriousness of misuse and abuse has emerged. However, intelligent CCTV, which maximizes detection of abnormal behavior, is of great help to prevent crime in the military and police. AI performs learning as taught by humans and then proceeds with self-learning. Since AI makes judgments according to the learned results, it is necessary to clearly understand the characteristics of learning. However, it is often difficult to visually judge strange and abnormal behaviors that are ambiguous even for humans to judge. It is very difficult to learn this with the eyes of artificial intelligence, and the result of learning is very many False Positive, False Negative, and True Negative. In response, this paper presented standards and methods for clarifying the learning of AI's strange and abnormal behaviors, and presented learning measures to maximize the judgment ability of intelligent CCTV's False Positive, False Negative, and True Negative. Through this paper, it is expected that the artificial intelligence engine performance of intelligent CCTV currently in use can be maximized, and the ratio of False Positive and False Negative can be minimized..

Recently, medical accidents related to surgical procedures have increased. In addition, the media reported that some of these accidents were involved in health crimes. Patient-advocate groups have called for mandatory establishment and management of CCTV in operating rooms. There is a lot of discussion among the interested parties, so it is necessary to review the relevant laws and regulations. The purpose of this study is to identify the characteristics of CCTV in operating rooms and to review legislations related to establishment and management of the CCTV in operating rooms. Medical institutions use CCTV for management of facilities and patient safety and install it in operating rooms optionally. The Constitution guarantees the privacy and the privacy of correspondence of every citizen, but it can be limited by the law for public welfare. Currently, however, there is no existing law about establishment and management of the CCTV in operating rooms and it can be defect of legal system. Under the current legislations, it is likely that the Self-determination can be violated due to the characteristic of healthcare provider when CCTV is mandatorily installed in operating room. In addition, the regulations on access and leakage of confidential information known by operator are insufficient. So that, the safety of the visual data might be threatened. Furthermore, unless the period and the place of storage of the visual data are clearly defined, it is highly unlikely to meet the original purpose of patient safety and prevention of medical accidents. This study is meaningful as there is few previous study on this topic although the need for legal review about this is growing and several bills are being proposed. It is expected that the results of this study can be utilized as basic data for enactment or amendment of the laws and regulations about establishment and management of CCTV in operating rooms.

As CCTV can be an effective tool to prevent or suppress crime at low cost, they have been widesoread in developed countries. In spite of their effectiveness, they infringe some constitutional rights such as the right to privacy, the right of likeness and the right to control over personal information. The police and ward offices install CCTV in public areas to prevent crimes without a legal basis or standard. When information obtained in such a way is used as investigation data for the police or as an evidence in a court, it can cause serious trouble. To solve this problem, legal restriction on the installation of CCTV as should be clearer. Since current laws on public agencies' protection of personal information are too general, they are not effective enough to protect personal information. Therefore, Personal Information Protection Organic Act should be enacted to make a legal basis for protecting comprehensive personal information. It should be obvious who installs CCTVs, who pay for the cost and how they are managed. Before installation, the police and ward offices should obtain residents' consent through a public hearing or voting (on the range and purpose of installation), or conduct an impact assessment. During installation, CCTVs should be limited to prevent or suppress crimes, keep public order and void dangers. In case of making a sign of installation, it must specify its rights. After installation(operation/management phase), they should abide by principles of information protection and try not to infringe constitutional right. In the cognitive aspect, the police should constitutional rights must be secured although it is important to carry out their missions. The police should serve citizens and change to the police of communities. Citizens should understand that constitutional right can be infringed if public order is not maintained. When citizens cooperate with the police, they fear of crimes will decrease.

The purpose of this research is to study, through the Delphi method, using an expert panel of 14 persons, effective workforce plans for CCTV applications. The need for professional manpower for activities related to CCTV has emerged through technological development and increased utilization of the CCTV industry sectors. Efficient workforce improvement for the CCTV sector presented in this study are in regards to student education. This study proposes an appropriate description for curriculum and related promotional information. This study should create an environment for overcoming the lack of student involvement and commitment to the environment and ensure training after qualification status after the training provided, including measures to maintain. In order to prevent employee turnover, CCTV training is necessary to actively review government support measures. This study also proposes providing a proper educational environment and supply of replacement staff members brought on by training courses. In terms of education administration bodies, we propose that education and training in CCTV management provide a variety of benefits including participation in education, adequate publicity through cooperation with relevant institutions, and introduces new educational programs. We propose providing adequate training that meets the needs of consumer, as well as education, course selection and expanded curriculum in accordance with operating options and the costs of training. In addition, senior student-selected personnel are needed to address the shortage of operators starting work-experience or training.

Objective: The purpose of this study is to critically analyze the process of framing child abuse cases through the news coverage after the enforcement of mandatory CCTV installation policy which was initiated in 2015. Methods: The research uses the revised and supplemented frame analysis tools developed by Iyengar (1990) and Semetko and Valkenburg (2000) to investigate 25 broadcasting news reported by KBS, from September 2015 to December 2017. Results: First, according to the formal analysis, the reports on abuse cases prove to be either a mixed or episodic frame which covers the cases heavily based on a particular incident rather than holistically looks into the situation. Second, in content analysis, child abuse news is delivered mainly through "human interest frame." Conclusion/Implications: The study identifies three dominant discourses formed as a result of the child abuse CCTV news: 'CCTV is a all-around player' discourse, 'preschool teachers as potential criminals' discourse and 'preschool teachers as nonprofessionals' discourse. This study is significant in that it presents that mass media do not always say the truth, but frame social issues within an ideological delivery system.

We propose a method to train a model that can predict the probability of a crime being committed. CCTV data by matching criminal events are required to train the crime prediction model. However, collecting CCTV data appropriate for training is difficult. Thus, we collected actual criminal records and converted them to an appropriate format using variables by considering a crime prediction environment and the availability of real-time data collection from CCTV. In addition, we identified new specific crime types according to the characteristics of criminal events and trained and tested the prediction model by applying neural network partial least squares for each crime type. Results show a level of predictive accuracy sufficiently significant to demonstrate the applicability of CCTV to real-time crime prediction.

Recently CCTV system is installed widely purpose to enhanced physical security, gathering criminal evidence and management of facilities. In spite of supporting strong management function, CCTV system has weak security function. Therefore high security management function is required. Generally it's not easy to control the devices under NAT using a NMS(Network Management System). So we design and implement alive check algorithm of CCTV devices under NAT using DVRNS address resolution and TCP session check. We evaluated and analyzed of developed system on real environment which includes about 100 DVRs under NAT. As a result of test, it showed that device alive check and DVRNS address resolution were well performed without any error.

CCTV inspection method has been used in Korea for more than 20 years, but there is no proper assessment system for sewer failure severity that considers the domestic circumstances. This study classified the defects caused by the overburden load of reinforced concrete sewer pipes depending on severity and developed defect code by analyzing the domestic CCTV inspection videos. The defect score was assigned to each defect code, and it was classified into 5 grades for the decision-making of repair and rehabilitation. The result of this study is expected to be useful for domestic CCTV inspectors to assess the sewer condition and helpful for managers to make a decision of repair and rehabilitation.

CCTV 는 범죄상황 발생시 보안과 증거확보를 위해 사용되어 왔다. 실제 상황에서 범죄가 발생하기 전 예방을 하는 것 보다 사후 처리에 용도를 두고 있으며, 범죄 상황에서의 보행자에 대한 행동을 미리 예측하기 어렵다. 본 논문에서는 노상에서 CCTV 로 수집된 데이터를 통해 객체 인식 및 객체간의 관계를 파악한다. 파악된 객체를 다중의 CCTV 연동 카메라가 추적하고 객체의 행동을 분석한다. 객체가 이상행동이라고 판단될 시 위협을 받는 객체 및 가까운 기관에 알림을 줄 수 있는 모델을 제안한다. 이를 통해 범죄 발생 전 즉각적인 대응이 가능하며 빠른 상황판단이 가능하다.
