This study is a demand research for the selection of public safety science and technology equipment and suggests an empirical research method. The technology demand survey is the beginning of the selection of innovative technology. And it is the basis of collecting information required for the technology required in the market and helping to apply it to the field. The demand survey for police science and technology can reduce the uncertainty of crime prevention and help the smooth implementation of security policies. However, in Korea, adoption of security science and technology equipment was centered on social issues or researchers' opinions rather than the demands of field users. Until, there was no research has been conducted on the demands of field police officers for selection of security science and technology equipment in Korea. Also, there was no preferential study for the demand for security science and technology equipment. Therefore, this study proposes a methodology that can systematically identify the needs for the technology and equipment of field experts suitable for the public security situation for the selection of security science and technology equipment. Specifically, we propose a sample design for a technology classification system and a survey tool for technology awareness and satisfaction. It is expected that this tool will provide a classification system for security science and technology equipment selected for the Korean police and will help determine the priority of equipment suitable for the field.

In this study, factors such as improvement of a fishing process and safety, reduction of the labor force and headcount and development of the automation technology for offshore (eel and crab) pot fishing vessels were analyzed. A questionnaire survey was conducted to analyze and select the key factors using independent/paired sample t-test and correlation analysis, and a living lab was operated with ship owners, skippers and experts to discuss practical needs of the site. From the result of questionnaire survey and field requirements, it was possible to understand the level of awareness of ship safety, general safety equipment, fishing work process and fishing safety equipment from the point of view of the field. In addition, there were differences in the measurement results of each items because the working environment and experience were different according to the position of the ship owner and the skipper. The results of the questionnaire survey and various perceptions of field stakeholders were reflected when analyzing the fishing system and fishing process to choose the development equipment applicable to the field. From the analysis results, the selected development equipment based on the fishing equipment and process currently in operation are pot washing device, catch separation and fish hold injection device, length limit regulations and bait ejection device after use, automatic main line winding device, bait crusher, automatic (crab) pot hauling separator and so on.

The purpose of the study is to analyze how to document survey and repair data on wooden architecture culture assets. Documentation was analyzed in comparison to digital developments from the past to the present. Although the accuracy of survey equipment has been improved by digital development, survey drawing has not changed. For example, a 3D Scanner, survey equipment, was introduced but is being used for conversion into 2D data. Data provided by the drawing included in the survey and repair reports were not accumulated. As it stands, it is inaccessible and disorganized. Data generated from the survey, repair, and maintenance has to be consistent. A BIM system was proposed to integrate information on wooden architecture cultural assets.

Purpose: This study aimed to evaluate the effect of information regarding health and safety risks on the subjective health status of workers using data from the Fifth Korean Working Conditions Survey. Methods: Among the survey respondents, 30,094 people classified as salaried workers, of which 8,513 (28.3%) used protective equipment. Results: Although the majority of workers using protective equipment reported being well-informed about safety and health risks, 15% of them were still insufficiently informed. Multivariate analyses have shown that the subjective health status of workers using protective equipment was significantly better if they received sufficient information. When the workers using protective equipment were classified by the kinds of hazards they were exposed to, the satisfaction of information was also significantly beneficial for the subjective health status of all groups. However, in workers who did not use protective equipment, information satisfaction did not appear to be a significant factor. Conclusion: These results suggest that when providing information on safety and health risks, it is necessary to focus on workers using protective equipment, for whom the effects of the policy are clearly expected.

PURPOSES : Most of the traffic surveys are carried out by an inspection method by the manpower. In some cases, the video equipment is used only in some regions when the traffic volume is surveyed. In this case, there is environmental restriction that the road equipment to fix the video equipment should exist. Also, in areas where information such as digital maps and satellite photographs is old or not provided, they are forced to rely on manpower research, but it is difficult to put huge amounts of time and money into the research in places where labor supply and demand is difficult. This difficulty is particularly pronounced in overseas business. METHODS : The purpose of this study is to improve the efficiency of business by using the drones in the traffic investigation through analysis of the cost reduction effect between the existing method and the proposed method in the overseas business traffic survey. The scope of the research is limited to the scope of research, and based on the case of overseas projects, the method of using drone for each research sector is suggested. RESULTS : In the traffic condition survey section, we propose the use of drone for traffic survey and queue length survey, and it is confirmed that there is a cost saving effect of 16% ~ 27% compared with the existing method. In the road condition survey, we propose the use of drones for road surface linear survey, geometry survey, and obstacle survey, and it was confirmed that the cost reduction effect is 39% ~ 93% compared to the existing method. CONCLUSIONS : In addition to overseas business, it is expected that it will have a positive effect on research time and cost reduction by using drone in traffic survey in domestic area where labor supply is not easy or basic data is insufficient.
