Objectives: Using data from the 1styear of the 7th National Health and Nutrition Survey, this study administered a questionnaire to patients with oral damage and examined the type of medical care used based on the nature of the injury, further characterized by age group and sex. Methods: Of the 8,150 respondents, this study selected those who participated in the health survey and oral exam survey, excluding surveys with missing values, and set 7,681 people as the research participants. This study used SPSS Windows version 23.0(SPSS Inc. IL, USA) as the statistics program and applied the chi-square test (p) based on a complex sample and logistic regression analysis. Results: In the analysis of the type of tooth damage, there was a significant difference (p<.001) in the number of male patients who were injured due to exercise, violence, and safety accidents compared to females. However, there was no significant difference in their type of medical security and whether or not they visited a dental clinic. The patients with private insurance showed relatively high use for tooth extraction and oral surgery (p<.001). Conclusions: The best way to prevent tooth damage is to prevent the accident. For sports or exercises which may cause tooth damage, protective gear, such as a mouthpiece, should be used to prevent tooth damage.

The data wiping is a technique which perfectly deletes data in a storage to prevent data recovery. Currently, management of stored data is important because of increasing an accident of personal information leakage. Especially, if you need to discard data contained personal information, using a wiping tool which permanently deletes data to prevent unnecessary personal information leakage. The data wiping is also used for data security and privacy protection. However the data wiping can be used intentionally destruction of evidence. This intentionally destruction of evidence is important clues of forensic investigation. This paper demonstrates the methods for detecting the usage of wiping tools in digital forensic investigation.

This article summarizes the structure of China's current social health insurance system and reviews the development status of China's private health insurance (PHI). China's medical security system is mainly composed of two parts: basic medical insurance (BMI) and PHI. Among them, the BMI provides reimbursement of basic medical expenses for the insured persons according to different proportions. PHI is a necessary supplement to the BMI and provides assistance to the insured persons in the event of illness or accident. By having PHI, people can obtain medical protection outside the coverage of BMI. In the development of PHI in China, the total medical cost is high and the insurance market size is large, but the proportion of PHI expenditure is low and the personal burden is high. Through this Chinese case, it will be helpful for mutual development between Korean PHI and national health insurance, for Korean insurance companies to enter the Chinese market, and for removing the medical burden on the people.

As the safety level of nuclear power plants (NPPs) relates to the safety of individuals, society, and the environment, it is important to establish NPP safety goals. In Korea, two quantitative health objectives and one large release frequency (LRF) criterion were formally set as quantitative safety goals for NPPs by the Nuclear Safety and Security Commission in 2016. The risks of prompt and cancer fatalities from NPPs should be less than 0.1% of the overall risk, and the frequency of nuclear accidents releasing more than 100 TBq of Cs-137 should not exceed 1E-06 per reactor year. This paper reviews the hierarchical structure of safety goals in Korea, its relationship with those of other countries, and the relationships among safety goals and subsidiary criteria like core damage frequency and large early release frequency. By analyzing the effect of the release of 100 TBq of Cs-137 via consequence analysis codes in eight different accident scenarios, it was shown that meeting the LRF criterion results in negligible prompt fatalities in the surrounding area. Hence, the LRF criterion dominates the safety goals for Korean NPPs. Safety goals must be consistent with national policy, international standards, and the goals of other counties.

As the number of kids cafes, one of the children's playgrounds, is increasing rapidly, safety accidents in the kids cafe are also increasing rapidly. The facility is also increasing as the need increases, but it is spreading without ensuring safety. In particular, the Ministry of Public Administration and Security for children's play facilities in the kids cafe, and the Ministry of Culture, Sports and Tourism for organic organizations are divided into different departments, so it is not easy for local governments to manage and supervise the actual business, and there are safety blind spots. Kids cafes have changed rapidly according to needs of children and guardians who are users, and there are many problems associated with them. Therefore, we identified problems that may arise due to insufficient safety management systems for kids cafes, investigated the safety management related to kids cafes in advanced countries, and compared and analysed them with domestic systems. As a result of the research, we proposed a safety management reinforcement system, and we hope to contribute to the reduction and prevention of kids café safety accidents.
