The Korea's safety standards for vehicle have been strengthened to reduce casualties from traffic accidents since 1962. The standards have a rather complicated structure. The safety standards are composed of the main text and asterisks, and the safety standard implementation rules are composed of the main text, asterisks and appendices, and items of the same name are stipulated in other chapters within the safety standards. This study is to suggest improvement measures such as simplifying the structure of these safety standards and integrating safety standard items with the same name. Through this, users' understanding of the standards will be improved, and it is expected that the system will be more efficient such as securing safety quickly through harmonization with international standards following the development of rapidly changing new technologies such as automated vehicles.

Safety has once again emerged as a social issue due to the enforcement of the Serious Disasters Punishment Act and the occurrence of major disasters recently. As such, the safety culture related to unsafe human behavior is drawing attention as various discussions about the importance of safety and accident prevention are currently being undertaken. This study aims to determine whether changes in the level of safety culture in companies affect the accident rate. To this end, we targeted three workplaces in the same company in the domestic manufacturing industry, and 2,790 people were surveyed using DNV's Safety Will(ISRS-C version 4.0) for safety culture level diagnosis. The change in safety culture level and accident rate were compared and analyzed after carrying out safety culture level improvement activities for 5 years. As a result, the level of safety culture increased by 5.8 points, an overall improvement of 9.5%, while the total number of accidents decreased by 20%, from 5 to 4, indicating a general decreasing trend in accident occurrence. Results confirmed that the change in the level of safety culture affects the accident rate, and the improvement in the level of safety culture affects a reduction in accidents. Therefore, this study suggests that efforts to improve the level of safety culture within a company can be associated with accident reduction and accident prevention outcomes.

Many railway safety measures reduce railway fatalities into half for last 10 years. But more improvement in railway safety is required to meet the social need after railway fire accident in Daegue. Reasonable railway safety index is needed to find out the weak point and efficiencies of various safety measures. But we still have only 2 kinds of safety index which are set for 10 years ago. In order to derive guideline for setting up safety index, we analyze accident cause, previous studies for railway safety improvement in Korea, and other countries safety plan. As a result some proposal for safety index was driven in this study.

Recently, the number of facilities and users of zipline which is the most popular among extreme leisure facilities has been increasing year by year. Zipline is a means of transporting durable wire between two timber or stay and moving the trolley connected to the passenger at high speed in the opposite direction. However, due to the nature of the zip line facility, the risk of accidents is always present and safety accidents are frequently occurring. Therefore, this study investigates the current state of safety management and extract the problem in terms of safety management through analyzing the installation state of zipline facilities in the case of accidents and reviewing of similar facility regulations. In order to solve this problem, we will contribute to establishment of comprehensive and systematic countermeasures and establishment of safety improvement system by suggesting measures to improve safety management through analyzing foreign regulations and safety management regulations for zipline and other extreme leisure facilities.

This paper introduces stress monitoring system for buried gas pipeline in poor ground. During the six months of improvement construction of poor ground, maximum settlement of gas pipeline is about 40 cm. This value represents relative small compared to the initial settlement estimation of ground improvement construction plan, 90 cm. Also, this paper includes the result of finite element analysis of gas pipeline to confirm safety of pipelines in poor ground. The stress monitoring system for gas pipeline was developed to guarantee the safety of buried gas pipeline in poor ground. Eventually, the ground improvement workings are ended safely and it is proved that the pipeline has no safety problem.

Public rental housing in Korea has been initially provided for residential stability of low-income household focusing on solving quantitative insufficiency since 1980s. In the process of early stage of designing and planning public rental housing, qualitative aspects of considering children were not primary concern. This study aims to analyze the priority of environmental improvement of outdoor spaces for children's safety in public rental housing. First, literature review was performed in the reference of local residential safety guidelines, Universal Design, and CPTED guidelines. In each guidelines, common safety planning factors for children were extracted within different types of outdoor spaces. Second, based on literature analysis, residents evaluated importance and satisfaction level by different safety types, outdoor space type, and environmental planning factors. In results, residents evaluated high importance and showed low satisfaction for crime and traffic safety. Through IPA, facilities and parking space was evaluated where improvement is needed for the first priority, and planning factors were mostly concerned with surveillance and safety management system. Result shows general concern of public rental housing residents, about weak facility management and security system, and about socially isolated environment which heightened the fear of crime safety. Overall, poor maintenance of the complex environment and decrepit facilities are constantly raising risk of safety accidents especially for children. Considering residents' concern, environmental improvement should be considered in perspective of not only physical repair, but also facility management and security system.

The purpose of this study is to assess legal improvements needed for extended application of smart technologies in construction sites. To achieve the objective of this study, at first, a literature review is conducted to define the concept of construction safety. Secondly, the statistics of construction accidents are assessed and systems and policies for construction safety in developed countries are then analyzed. Also, the applicability of smart safety technologies in the field is examined through recent application cases of construction & related industries. Finally, institutional issues related to the application of smart technology are assessed and policy improvement directions are then introduced. As a result, additional development of smart technologies for small construction sites and continuous policy supports are required. This study will be used as a baseline data for the institutional improvement related to smart construction technologies for domestic construction sites.

The improvement of safety and health education method in construction site was investigated through the survey for workers and delphi technique. The results of preliminary survey done for workers were analyzed using the multi variance analyses, and the questionnaires for delphi survey were composed based on the results of preliminary survey. Finally, the participatory safety and health education method was suggested. The result showed that most of workers were very interested in accident prevention and health. On the contrary, they did not actively participate in safety activities in sites including safety and health education. In order to improve workers' levels of safety consciousness and prevent the construction accident, the participatory safety and health education method that construction workers directly examine and give presentations about accident causes and measures was suggested and verified by tests. One-way instructor-led safety and health education used widely and participatory safety and health education with workers were carried out by dividing participants into two groups. After education, the examination is done for two groups. The test results found that the average score of safety consciousness of the worker group that received participatory safety education was higher than that of the work group that received instructor-led safety education. And the Delphi technique utilizing experts was analyzed that participatory safety education has a great effect on improvement of workers' level of safety consciousness.

In this paper, we studied the structural design for safety improvement of the winch mount of the armored recovery vehicle. From the finite element analysis using the safety factor of the original winch mount, the results determined that the safety factor was very low, namely 1.14 at $-15^{\circ}$ when towing the maximum force. For considering the usage and safety, the safety factor needs to increase to between 1.4 and 1.6. To improve the safety factor, a re-design, such as shape modification and strengthening the welded zone, was performed. After the improvement of the structural design, the safety factor of the improved mount was calculated at 1.78, an increase of about 56.1% from that of the original mount.
