For improving social safety, It is important to build Web DB of criminal prevention and open to the public. It could be help to mitigate social damage of crimes and accidents. In this study, the main goal is to analyze and apply the applicable contents from user demands studies and case studies for a domestic life safety Web DB. For this study 31 cases of international life safety Web DB were collected and analyzed. Customer participation style of Web service was reviewed. And demand survey for crime weakness group like students, and young women was examined. As a results people needed to know the un-safety area in their usual life and their ways; school to home, work to home. While creating the Web DB for domestic life safety, user content according to different economic status and publicity for Web DB proved to be important factors.

The purpose of this study was to develop and evaluate the educational program of life safety for low grade elementary school students. The objectives of the life safety education were established, and the contents and instructions of the educational program were organized according to the needs of the 560 children and their mothers. Both experimental and control groups were evaluated before, immediately after and 3 weeks after the education in terms of knowledge about safety, attitudes and behaviors. The results of this study were as follows: 1. Twelve contents for safety education consisted of safety for electronic games, playing facility, mobile exercise machines, elevator/escalators, traffic and prevention for injury, pricking/cutting, collision/fall/slippery, drowning, burning, electric shock, food toxicity and child missing/sexual harassment/kidnapping. 2. The score of knowledge for safety, attitude, and behavior of the experimental group was improved after the post-tests. Thus, the educational effects were demonstrated to be significant in all evaluation sections.

In spite of frequent defect in industrial boilers, life assessment or diagnostic method for them has not been actively studied. In this research, SS400 carbon steel used in industrial boilers is simulated with artificial aging heat treatment. To do qualitative life assessment, differences in micro-structures and hardness of SS400 by the degradation time are studied. In addition, variation in material properties by aging was observed with the tensile test at room temperature and $179^{\circ}C$ and changes in ductile to brittle transition temperature was observed with the charpy impact test performed at several test temperature.

There is no satisfactory level of active living safety platform that collects, stores and intelligently analyzes disasters such as natural disasters, social disasters, and cyber disasters that threaten the safety of civic life. The purpose of this study is to contribute to the improvement of quality of life through the development of science and technology through the design of a life safety platform that actively services the safety of citizens' lives.

The purpose of this study is to reveal the causal relationship between the demographic characteristics of international students living in Korea and the effect of Korean language level on safety awareness. It was confirmed that there was a significant difference in all areas such as life safety awareness, fire safety awareness, and disaster safety awareness depending on the area of residence. The results to analyze the effect of Korean language expression and comprehension ability on safety consciousness are as follows. First, it was found that Korean expression ability had a positive (+) effect on life safety awareness but did not have a significant effect. Comprehension ability had a negative (-) effect on life safety awareness but did not have a significant effect. Second, it was found that Korean expression ability had a significant effect on fire safety awareness and had a positive (+) influence relationship. Finally, it was found that the Korean language expression ability had a significant effect on disaster safety awareness and had a positive (+) influence relationship. It is necessary to strengthen the awareness of safety for international students while staying and living in Korea, and when teaching Korean, Korean language comprehension education on safety-related topics as well as daily Korean must be strengthened.

LysR-type transcriptional regulators (LTTRs) contain an N-terminal DNA binding domain (DBD) and a C-terminal regulatory domain (RD). Typically, LTTRs function as homotetramers. VV2_1132 was identified in Vibrio vulnificus as an LTTR that is a homologue of HypT (also known as YjiE or QseD) in Escherichia coli. In this study, we determined the crystal structure of full-length VV2_1132 at a resolution of $2.2{\AA}$, thereby revealing a novel combination of the domains in the tetrameric assembly. Only one DBD dimer in the tetramer can bind to DNA, because the DNA binding motifs of the other DBD dimer are completely buried in the tetrameric assembly. Structural and functional analyses of VV2_1132 suggest that it might not perform the same role as E. coli HypT, indicating that further study is required to elucidate the function of this gene in V. vulnificus. The unique structure of VV2_1132 extends our knowledge of LTTR function and mechanisms of action.

Purpose: The purpose of this study is to enable users to conveniently report risks by automatically classifying risk categories in real time using AI for images reported in the life safety prevention service app. Method: Through a system consisting of a life safety prevention service platform, life safety prevention service app, AI model serving server and sftp server interconnected through the Internet, the reported life safety images are automatically classified in real time, and the AI model used at this time An AI learning algorithm for generation was also developed. Result: Images can be automatically classified by AI processing in real time, making it easier for reporters to report matters related to life safety.Conclusion: The AI image automatic classification system presented in this paper automatically classifies reported images in real time with a classification accuracy of over 90%, enabling reporters to easily report images related to life safety. It is necessary to develop faster and more accurate AI models and improve system processing capacity.

Asian Branches of International Life Science Institute (ILSI), i.e. China, India, Japan, Korea and South East Asian Region, identified five key public health issue priorities of each region and compared the results. In case of China, India and South East Asian countries (Indonesia, Malaysia, Philippines, Thailand etc. ASEAN countries), communicable diseases were the first priority issue, while elderly issue and food safety were prime issues for Japan and Korea, respectively. Malnutrition was the second priority issue for India and ASEAN countries, whereas non-communicable disease like cancer and degenerative diseases was for Korea and China, and obesity far Japan. Typical issues were smoking for China, nutrition education for China and Japan, biotechnology aiming GMO for India, and functional food causing health claim problem for Korea and Japan. Although the priority varied with the socioeconomic situation of each county, food and water safety recorded the highest priority of all the countries. The key public health issues of Korea were discussed in detail.
