  • The International Maritime Organization (IMO) is promoting the introduction of e-Navigation that prevents maritime accidents by fusion of Information & Communication Technology (ICT) with ship operation technology. In Korea, Korean e-Navigation is also being developed for fishing vessels and small vessels sailing offshore, which are vulnerable to maritime accidents. However, for the successful development of Korean e-Navigation, it is necessary to develop an indicator that can evaluate the development performance so that the development performance that has been progressed so far can be evaluated and the development direction can be re-established. Therefore, this study attempted to develop an evaluation index tailored to the development goal of e-Navigation service centering on the collision accident, which is a major maritime accident. In this study, a collision accident evaluation index for e-Navigation service was developed by deriving and quantifying the root cause of maritime collision accidents using Root cause analysis(RCA) and fault tree analysis (FTA) techniques. This indicator is considered to be helpful in reducing maritime accidents as it is used as a development indicator for e-Navigation and an indicator for maritime collision accident analysis.

  • There is no safety evaluation index with marine accidents and information of ship's safety management result for good grasp of safety management level of shipping company and effective monitoring. In this paper, we proposed a SMEI(Safety Management Evaluation Index) for evaluation of shipping companies. The SMEI is consist of MAR(marine accidents ratio), SSMR(ship safety management ratio) and SAP(safety advantage point) through brainstorming of the expert group and AHP(analysis hierarchy process)in previous study. And weights of SMEI are calculated using experts's opinions through the Delphi method. We also verified the validity of proposed SMEI to 119 Korean shipping companies with 916 ocean-going ships of Korean flag, which grouped three part (small, mid and big) by number of ship and gross tonnage. And we found out 19 shipping companies, 8 companies in group1 & group2 respectively and 3 companies in group 3, with score below 1.0 by SMEI. In these companies, there are no marine accidents in recent 3 years and appeared low frequency remarkably in the detention and mojor non-conformity by data analysis.

  • This study quantitatively and qualitatively analyzes the physical environment for health promotion in urban parks by indicators that were selected in consideration of overseas cases and previous studies. To evenly distribute the areas to be evaluated by region, Seodaemun Independence Park, Hongneung Park, Gocheok Park, Sillim Park, Cheongdam Park, Gaepo Park, and Sungin Park were selected among the old neighborhood parks already established in Seoul. The evaluation indicators consist of quantitative indicators (12 factors classified into the three categories of the surrounding environment, the park characteristics, and the park facilities) and qualitative indicators (14 factors classified according to the five categories of accessibility, safety, convenience, activities, and amenities). These indicators were selected after conducting advisory meetings with experts in the field. The physical environment perception factors were evaluated by experts and investigators by field inspections and were rated on a three-point scale (high, medium, low). According to the results of the analysis, first, not only were exercise facilities and trails, but also various factors which support health activities, such as rest areas, leisure spots, and cultural facilities, as well as accessibility, cleanliness, and drinking water facilities are important indicators for health promotion. Second, even if the requirements are met for quantitative factors, several inconveniences hinder the actual implementation or use in the qualitative evaluation. Thus, both quantitative and qualitative evaluations must be simultaneously performed for the proper judging of the physical environment of a park. Third, upon conducting a qualitative evaluation of the physical environmental factors, score differences depended on the evaluated categories in each park. These differences show that indirect indicators, such as accessibility, safety, and facility convenience are insufficiently equipped compared to direct indicators, such as activity, which includes exercise facilities and fitness centers for health promotion. As the utilization rate of parks is increasing due to COVID-19, more efforts should be made to improve park services in the post-corona era. To promote such services, it is necessary to regularly evaluate parks based on both quantitative and qualitative indicators and to contemplate services not only through direct factors but also indirect factors and security measures.

  • In-vehicle warning information systems(IWIS) is an effective countermeasure for preventing traffic crashes. It provides drivers with warnng messages about upcoming hazards to draw proper evasive maneuvering. This study developed a methodology for evaluating the effectiveness of IWIS based on an integrated index to identify driver's responsive behavior. The proposed index consists of characteristics of longitudinal and lateral behavior of vehicle maneuverings. Also, a method to assign mixed-weights in the context of multi-criteria decision making framework was adopted to develop the evaluation method. It is expected that the outcome of this study is useful in designing more effective in-vehicle warning information systems.

  • This study aims to analyze safety indicators for various types of pedestrian accidents (traffic accidents, crimes, crowd crush incidents, and falls) in urban community roads. The need for this research arises from the complexity and narrowness of these streets, which significantly threaten pedestrian safety. The study employed literature reviews, case studies, and field surveys to identify risk factors for pedestrian accidents. These risk factors were then systematically evaluated using the Analytic Hierarchy Process (AHP) to determine the relative importance of each safety indicator. The analysis revealed that for traffic accidents, factors such as the separation of pedestrian and vehicle paths and the effective sidewalk width are critical. For crime-related incidents, lighting and CCTV coverage were found to be the most important. In crowd crush incidents, pedestrian traffic volume and effective sidewalk width were identified as key indicators, while slope and effective sidewalk width were crucial for preventing falls. These findings contribute to the development of targeted safety improvement measures for urban community roads.

  • Korea Post service provides public services to the public, including mail, deposits, and insurance. The work of the postal activities is labor-intensive and physically intensive. Postal workers are exposed to the risk of injury and musculoskeletal disorders, and delivery workers are exposed to the risk of traffic accidents. The Postal Service Headquarters has strengthened safety and health activities to improve hazardous risk factors in the field. In addition, we are promoting activities to spread safety culture continuously. However, it is difficult to determine whether these activities were applied well to the site of the affiliated institution, and it is not known whether they were effective in preventing safety accidents. In addition, there is no objective evaluation system, so the current level of safety and health and problems related to workplace safety and health cannot be identified. Therefore, in this study, we tried to prepare basic data to propose an evaluation system, standard, and evaluation index suitable for the postal business so that the safety level of the public postal business can be evaluated efficiently and objectively. In other words, it was intended to analyze the characteristics of the public postal business and prepare the basis for the development of evaluation indicators considering it, and through this, an effective level evaluation can be performed and problems in safety and health management by institution can be identified.
