Analyses were performed with Rosenberg Self-esteem Scale. The population was 1,391 Korean workers in total. Subjects who get scores of self-esteem lower than those before the accidents were 539 people(42.34%). On the other hand, subjects who get the same or higher scores of self-esteem than those before the accidents were 802 people(57.66%). The average score of the whole showed 30.09 point that is higher than 29.99 points that were analyzed from primary panel data. The odds ratio of self-esteem is analyzed to find that what is the most important factor for improving self-esteem of the workers group. The result of odds ratio analysis was 1.60 in the not-to-return-to-work group, significantly higher of the score of self-esteem than the return-to-work group. The statistically significant odds ratio of unemployed workers group from the group of workers who return to work prove the academically conventional social norms. This result shows that the workers condition, whether or not they can return to their work, affects the workers‘ self-esteem. Therefore, the workers' condition for returning to the work should be considered the most important service for Korean workers' compensation and welfare services.

The risk-based assessment, also called time-based assessment of structure is usually performed to provide seismic risk evaluation of a target structure for its entire life-cycle, e.g. 50 years. The prediction of collapse probability is the estimator in the risk-based assessment. While the risk-based assessment is the key in the performance-based earthquake engineering, its application is very limited because this evaluation method is very expensive in terms of simulation and computational efforts. So the evaluation database for many archetype structures usually serve as representative of the specific system. However, there is no such an assessment performed for building stocks in Korea. Consequently, the performance objective of current building code, KBC is not clear at least in a quantitative way. This shortcoming gives an unresolved issue to insurance industry, socio-economic impact, seismic safety policy in national and local governments. In this study, we evaluate the comprehensive seismic performance of an low-rise residential buildings with discontinuous structural walls, so called piloti-type structure which is commonly found in low-rise domestic building stocks. The collapse probability is obtained using the risk integral of a conditioned collapse capacity function and regression of current hazard curve. Based on this approach it is expected to provide a robust tool to seismic safety policy as well as seismic risk analysis such as Probable Maximum Loss (PML) commonly used in the insurance industry.

The safety accident has been repeatedly abolished and resurrected according to the social atmosphere and the issue of the effectiveness of education has been constantly raised. As shown in [Figure 1], the training of the manager, During the ten years of revival due to the amendment of the law in 2007, the accident rate further increased. Industrial accidents often occur in combination with unsafe behavior and unsafe conditions. Unsafe behaviors are indispensable factors in the work that human beings engage in. In order to prevent accidents, it is imperative to establish systems and measures to understand the more obvious causes.

A confined space means places where the risk of damage to health caused by lack of oxygen or hazardous gases in inadequate ventilation conditions and the risk of fire and explosion caused by flammable substances. Asphyxiation accidents in a confined space occured every year and also occurred more than two people at the same time. In this study, we surveyed the domestic statistical data occurred the lack of oxygen in confined space for the last 10 years(2006-2015) and, analyzed the accident by industries sector, workplace size etc. 17 fatal work accidents that occurred in confined spaces in Korea between 2013 and 2015 were investigated and analyzed using the database of the KOSHA and suggested interventions to minimize asphyxiation accidents in confined spaces. This paper is expected to be used to establish interventions planning and training as a preventive measures in workplace having confined spaces.

The regulation for industrial accident rate level assessment of construction companies was introduced to the construction industry in the Republic of Korea since 1993 and has brought positive outcome on industrial accidents reduction at construction work sites. There were considerable decrease of industrial accident ratio and enforcing of contrators' safety organizations from the beginning of the regulation for industrial accident rate level assessment. In spite of these positive outcomes, there were some negative effects such as contractors' shrinking accident reports to keep good accident ratios since these figures had a great impact on pre-qualification stage of bidding when general contractors were competing for new construction projects. In addition, Comprehensive evaluation bid system, which replaces the lowest price bid system is applied to government-ordered construction projects since 2016. Comprehensive evaluation bid system includes construction company's accident rate as one of the evaluation items and carries out with the industrial accident rate level assessment of construction companies at the same time. The regulations of two systems have been called for improvement to unify these different procedures and standards which have led business stakeholders to confusion for several years. This study aims to devote on lessening shrinking accident reports and to reduce the waste of business stakeholders through changing the regulation for industrial accident rate level assessment.

The trawl fishery is an important fishery accounting for around 30.0% of adjacent water fishery production in Korea, and the commercial fishing is associated with high rate of fatal and non-fatal occupational injury. The hazard analysis for the fishermen's safety of offshore trawler was conducted to serve as basic data for improving the healthy and safe working environment of fishermen using fishermen's occupational accidents of the national federation of fisheries cooperatives (NFFC) from 2012 to 2014 (n=464). As a result, the occupational accident occurrence rate of large powered trawl fishery was 241.4‰ in east sea trawl fishery, 6.9 times the rate of that. In addition, death and missing rate was found to have very serious level management to 97.7‱ in east sea trawl fishery of death at 6.2 times. The accident occurred in 91.7 to 100.0% was happened at sea. The slipping, others and struck by object and son on occurred more frequently in order in the frequency of accident occurrence pattern. However, the occurrence rate of death and missing did not match the frequency of accident pattern. In other words, slipping occurred more frequently while death and missing risk was not high. The fall in the waters was low while death and missing risk was high. The results are expected to help identify and assess safety hazard occurred in offshore trawlers.

Due to increased demand for remodeling and repair in construction market in recent year, the usage of horse scaffold is increasing in the indoor finish works. Injuries related horse scaffold are mainly caused by poor installation or of careless handling of scaffold. Approximately 300 workers are injuried at construction site every year, it is accounting for about 1.5% of the total construction sector and has increased on a year-to-year trends. But the main contents between national standards and speccifications related to the manufacture and usage of horse scaffolds are mutually inconsistent, In particular, the rules on occupational safety and health standards are the basis for the prevention of industrial injuries, there is no explicit application being made to the horse scaffold commonly used on construction sites. The purpose of this study was to analye the manufacture and usage situations in order to reduce construction injuries that occur at the horse scaffolds. It will be utilized the results of the analysis as the basis data for unifying the major domestic standards and specifications associated with the manufacture and usage of horse scaffold.

This study of small ＆ Medium-Sized construction sites construction disaster prevention technology conduction-site visits from the map results report by the inspector on-site advice and technical guidance for the analysis of deficiencies and potential construction of disaster revealed the potential factors causing an accident as follows. As a results, Should not be a once a month visits. Therefore should be changed at least twice a month to help prevent accidents of this system is to be judged.

This study conducted an on-the-spot survey on the 21 national and private forest roads in the Jeollabuk-do area in order to construct a GIS-based map of the disaster-prone zones in forest roads, and built the database of the locations of the disaster-occurrence and disaster-prone zones and disaster-prone zones. In addition, it built the DB with the Raster of size 10m x 10m using the GIS program after extracting the gradients, the forest shapes, the age of stand, and the soil properties factors by referring to a 1: 25,000 digital map, a detailed soil map, and a digital map of the forest shapes in connection with forest road disasters, and then built a rainfall distribution chart(Raster) after extracting the rainfall factors using the rainfall data of the Korea Water Resources Development Corporation. The map of the disaster-prone zone in forest roads was constructed through the combination of all the completed Raster charts and the applications of the Raster calculation(Raster calculator) technique. It is expected that with a more localized and more quantitative assessment, these study results will provide the base line data for a structural and managerial improvement of the forest roads.

Safety accident rate of small-medium construction site is high. because of lack of safety management system, lack of safety management capacity, lack of investment for safety, Owner's insufficient awareness about safety. In order to improve this, Currently in Occupational Safety and Health Act, Construction site of amounts more than 300 million won less than 120 billion (architectural),150 billion won(civil) mandatory subject to the technical guidance on construction accident prevention. Context of construction accident causes with construction accident rate relationship analysis and case analysis of technical guidance, through a survey of stakeholders in the technical guidance drawn the problems of the construction accident prevention technical guidance system and ways to improve on this.

In addition to improving economic growth and development of advanced production technology brings many benefits to our society, but if the growth of this still has the shadow of accidents exists. In particular, the construction site has seen a significantly higher accident rate figures despite efforts on disaster prevention. Among the various methods of reducing the need for disaster safety education industry it has become very stressed its importance through many studies. When a disaster causes significant share of the construction industry due to the lack of educational causes, including technical causes, managerial causes, classification and educational causes of this ateumyeo safety awareness and knowledge account for large proportion. In the health and safety education, centered on the subjects of education supervisors will be able to reduce the real and effective industrial disaster education should be run.

Earthquake event keeps increasing every year, and the recent cases of earthquake hazards invoke the necessity of seismic study in Korea, as geotechnical earthquake hazards, such as strong ground motion, liquefaction and landslides, are a significant threat to structures in industrial hub areas including coastal facilities. In this study, systemized framework of integrated assessment of earthquake-induced geotechnical hazard was established using advanced geospatial database. And a visible simulation of the framework was specifically conducted at two coastal facility areas in Incheon. First, the geospatial-grid information in the 3D domain were constructed with geostatistical interpolation method composed of multiple geospatial coverage mapping and 3D integration of geo-layer construction considering spatial outliers and geotechnical uncertainty. Second, the behavior of site-specific seismic responses were assessed by incorporating the depth to bedrock, mean shear wave velocity of the upper 30 m, and characteristic site period based on the geospatial-grid. Third, the normalized correlations between rock-outcrop accelerations and the maximum accelerations of each grid were determined considering the site-specific seismic response characteristics. Fourth, the potential damage due to liquefaction was estimated by combining the geospatial-grid and accelerations correlation grid based on the simplified liquefaction potential index evaluation method.
