Recently, carelessness on safety management in construction sites has caused a sharper upward trend in accidents and disasters, compared to the past. Therefore, this study analyzes the causes of accidents that occurred on construction sites in the year of 2010, and proposes preventive measures. The construction industry had a heavy death rate with 279 out of 418 deaths from falls in all industrial sites, accounting for 66.7%. And the causation analysis found a particularly high incidence of temporary structure-related accidents, with falling off scaffolding as the most common cause of accidents. According to the causation analysis of fall-down accident cases, accidents induced by protrusion on construction sites are a big contributor resulting in the deaths of 312, accounting for 74.8%, which is deemed to be due to site disorderliness. And to remove floor protrusions and to secure workers' traffic line and safety, neat and thorough site arrangement is necessary. Against collision, efforts must be made to prevent equipment-pedestrian crashes on site, which necessarily requires emergency lamps, alarm bells, and safety poles and blocks to be installed, lighting systems to be improved, obstacles to be removed, site supervisors to be assigned to construction equipment works, and workers to be more intensely trained and supervised.

Korea reached an aging society in 2000, and it is progressed quickly now. Government forecasts that the number of aged people over 65 years old will increase from 7.2%(2000) to above 14.3% among total population in 2018. Workers over fifty years old are increasing in construction field every year. These aged workers are exposed to various construction accidents, and also their accident rate is very high because of physical and psychological changes by aging. Specially, a disaster of aged workers more than 50 years old is fronted at the serious situation in the construction industry which has variable working environment. Thus, the purpose of this study is to suggest the precaution by analysing disaster characteristics of aged construction workers. Also, this study aims to present a basic counter-plan according to important safety management list which is abstracted from the work, aged construction workers' accident rate is high.

Recently, the importance of disaster prevention has emerged as serious accidents have occurred frequently, in which workers died or seriously injured at industrial sites. In response, the government enacted the 'Act on the Punishment of Major Disasters' to strengthen the responsibility, punishment intensity, and regulation of business owners for accidents at the site. In particular, the construction industry accounts for a large proportion of serious accidents, so safety levels need to be raised through on-site management. This study aims to reduce the occurrence of disasters at construction sites and to improve the work efficiency of safety managers. To derive detailed elements of the safety manager's work, domestic and overseas cases were investigated. The derived items were analyzed for the difficulty and preventive effects of the work through a survey of experts, and they will contribute to disaster prevention by presenting tasks to be focused and suggesting ways to improve inefficient tasks.

Industrial disasters cause lots of damages from individuals to companies and country. Especially, damages caused by constructional disasters take very large portion in the whole industry and are accompanied by huge personal physical damages. For the prevention of disasters, roles of safety manager are very important and especially, effects of disaster prevention can be changed by occupational ability of construction safety manager. To improve job abilities of safety manager, job education is very important. This research suggested a model for job education management of construction safety manager and proposed improvements as a study on improvement of curriculum for vitalization of job education of construction safety manager so as to improve occupational ability of safety manager. To achieve them, this research examined standard and operation status of current job education of safety manager and the problems and suggested a model materializing job educational contents as a measure to vitalize job education system of safety manager.

최근 산업재해의 전반적인 감소에도 불구하고, 건설업은 증가추세이다. 사고의 대부분은 안전관리자가 선임되어있는 규모가 큰 공사현장보다 다세대주택, 리모델링, 근생시설 등 규모가 작은 공사현장에서 많이 발생한다. 실제 사업장 규모별로 보면 전체 재해의 81.6%, 대부분이 120억원미만 50인미만 소규모 사업장에서 발생됐다. 본 연구에서는 단지형 다세대주택신축사업을 추진하는 소규모 주택업체의 안전관리 운영실태를 조사하고 분석하여 효시적으로 안전경영모델을 표준화시켜 적용했으며, 소규모 주택업체가 표준화된 안전경영모델을 쉽게 이해하고 실천하여 무재해를 달성하는데 목적이 있다.

Proper pre-safety training is one of core mandatory in order to reduce injuries at the construction fields. In this study, we investigate the employee's opinions of safety training, safety recognition, the actual conditions of safety through survey. As a result of study, incident factors are roughly divided into technical factor, managerial factor, and educational factor. We confirmed that the educational factor led by deficiency of safety awareness and knowledge was the major factor. It needs to be resettled or revised properly to match with the incident trends and the safety training curriculum should also be improved and drastically revised with special quality. The managerial workers' safety recognition is lower than the site ones regarding the correct understanding of the importance of the training.. It suggest that the education method and system in construction fields might have fundamental problems.

Purpose. Because traditional statistics approach had limitations in learning future forecasting and major factors causing occupational injuries in each industry, this paper develops a model forecasting and evaluating occupational injury rate by using a system dynamics model through the analysis of the industry injury statistics and the project for industry injury prevention. Method. The model of this paper consists of 12 total models such as a model of employees, of industrial disaster victims, of injury rate, etc.; In the analysis of firm size, it is classified and developed according to 12 groups on the basis of the number of employees, and in the analysis of industrial classification, it is done according to 10 total business fields such as manufacturing business, construction one, etc. Results. This paper suggests the methodology which forecasts industry injury rate by business field and size on the basis of developed model, and evaluates an industry injury prevention project from various angles. Conclusions. This paper deduced problem through the analysis of an industry injury by business fields and a comparative analysis of foreign cases, and analyzed to affect industry injury prevention by industry. And it also analyzed actual condition of industry injury, and did a difference in the level of safety consciousness according to the general characteristics of workers and occupational safety and health education related characteristics. In result, this paper suggests that analyzing occupational injury related factors, a safety budgetary allocation, and industry injury related factors can reduce illness costs such as employees' injury and medical care, and also assist cost for a disability.

The construction industry is the highest safety accident causing industry as 28.55% portion of all industries' accidents in Korea. In particular, falling is the highest accidents type composed of 60.16% among the construction field accidents. Therefore, we analyzed the factors of major disaster affecting the fall accident and then derived feature importances by considering various variables. We used data collected from Korea Occupational Safety & Health Agency (KOSHA) for learning and predicting in the proposed model. We have an effort to predict the degree of occupational fall accidents by using the machine learning model, i.e., Adaboost, short for Adaptive Boosting. Adaboost is a machine learning meta-algorithm which can be used in conjunction with many other types of learning algorithms to improve performance. Decision trees were combined with AdaBoost in this model to predict and classify the degree of occupational fall accidents. HyOperpt was also used to optimize hyperparameters and to combine k-fold cross validation by hierarchy. We extracted and analyzed feature importances and affecting fall disaster by permutation technique. In this study, we verified the degree of fall accidents with predictive accuracy. The machine learning model was also confirmed to be applicable to the safety accident analysis in construction site. In the future, if the safety accident data is accumulated automatically in the network system using IoT(Internet of things) technology in real time in the construction site, it will be possible to analyze the factors and types of accidents according to the site conditions from the real time data.
