Recently, controversy has been raised over the security and safety of Chinese-made network equipment (Huawei 5G), apps (TikTok, etc.). In particular, according to the results of the Ministry of Defense investigation in 2020, malicious codes were found in CCTVs made in China that were delivered as military surveillance equipment used as a coast guard system, and specific information was remotely transmitted to a Chinese server. The safety issues of these Chinese security products can be questioned as being systematically led by the state rather than by companies or individuals. In this paper, we perform network and process level analysis of 360 Total Security(360 TS), a Chinese antivirus software. In addition, it compares and analyzes the domestic cloud-based vaccine V3 Lite product. Through this, the safety of Chinese security solutions is checked and information leakage and risks are suggested.

This study is to examine the relationship between leisure activities, job satisfaction and quality of life among security agents. To attain the goal of the study described above paragraphs, private guards held in Seoul and Gyeong-Gi were set as a collected group. Then, using judgment sampling method, finally drewout and analyzed 333 peoples in total. The result of reliability analysis check up was here below; Chronbach's $\alpha$= .665-.816. The conclusion drawn from this study is as follows: First, it make no difference between leisure types in job satisfaction. Second, there is a difference between leisure type in quality of life. Third, the level of leisure activities results in the indirect, direct effect on quality of life through job satisfaction. Job satisfaction is an important variable intermediating the relationship between leisure activiteis and quality of life.

The object of this study is to examine the relations between leisure activity and duty stress and separation intention in private guards. The subject of this study is set up the private guards who are working at private guard company in a capital sphere. This study applyed the way of judgement abstraction and abstracted the total of 360 persons. However, the number used in the final analysis is 333 persons. The last conclusion in this study is as follows. Firstly, the relation between duty stress and separation intention has a matual effect meaningfully. Secondly, the physical stress hasn't an effect on the term of leisure activity, and separation intention. affects meaningfully the physical stress. Thirdly, the relation beween leisure activity and separation intention exerts a meaningful influence mutually in all sphere. Duty stress is a important parameter between leisure activity and separation intention.

The secondhand market in Korea has been showing steady growth. However, the number of fraud cases and the amount of damages from fraudulent activities in secondhand transactions are also increasing. As of 2021, the size of the secondhand market reached 24 trillion won, but the total amount of fraud-related damages reached 360.6 billion won. In order to prevent fraud between individuals, secondhand trading platforms have implemented a safety payment system. However, new types of fraud methods exploiting the safety payment system have emerged, undermining the security of secondhand transaction safety payments. In this study, we aim to utilize text mining to examine the current state of the safety payment system in secondhand transactions and propose improvement measures by analyzing the system through text mining and network analysis.

This study analyzed the direct costs of fall accidents, which have the highest accident rate, for domestic construction industry workers. Firstly, the average insurance payment per person due to fall accidents in the construction industry is around 19 million won (18,971,000 won). Given that the average number of workers suffering fall accidents over ten years is 5,863, the total cost of losses from fall accidents is about 1.1 trillion won (111,360,000,000 won). Secondly, a cost-based economic feasibility analysis was done to develop nonstructural preventive measures for fall accidents. Since there was no data expressing the costs and effects of preventive measures in terms of monetary value, the economic feasibility analysis was attempted with a focus on how much the newly introduced preventive measures can reduce the accident loss costs due to fall accidents. Thirdly, if the accident loss size is grasped and the preventive measures for the causes of fall accidents are developed and strictly implemented, the insurance fee that can reduce the accident loss costs can be determined. Further study is needed to estimate the benefit of the accident loss cost reduction seen from the cost-based approach method.
