Accident rate in the construction industry of South Korea is increasing every year, and it represents the highest percentage among industries. This shows that activities performed to prevent safety accidents in the country are not efficient when it comes to reduce the accident rate. In order to resolve this issue, a model for the prediction of human accidents should be established. In addition, it is required a quantification study based on pattern of human accidents. Therefore, the objective of this study is to quantify uncertainty of human accidents risk and predict how to change in various circumstances by using Monte Carlo Simulation. To achieve the objective, first, pattern of human accidents was defined. Second, insurance claim payout and information of human accidents during 14 years in construction site were collected. Third, descriptive analysis is conducted to determine the characteristics of the accident pattern. Fourth, to quantitatively analyze the pattern of the human accidents, the population of each accident occurrence and payout were estimated. Finally, estimated populations was analyzed according to characteristics of distribution by using Monte carlo simulation. In the future, this study can be used as a reference for developing the safety management checklist in construction site and development of prediction models of human accident.

산업재해라고 하면 으레 육중한 기계장비가 시끄럽게 돌아가는 공장이나 위험이 항상 도사리는 건설공사현장과 같이 육체노동을 주로 요하는 사업장엣 일어나는 사고를 떠올리곤 한다. 그러나 현대 산업사회에서는 오히려 업무와 관련한 스트레스나 과로, 정신적 노동으로 인한 질병 등에 의한 산업재해가 많은 비중을 차지하고 있고, 법원 역시 근로자인 원고 측에서 인관관계를 구체적이고 직접적으로 입증하지 못하더라도 어느 정보 개연성이 인정된다면 산업재해를 인정해 주는 추세에 있다. 근로자에게 예상치 못한 재해가 발생하면 피해자 개인에게도 매우 불행하고 힘든 일이지만, 회사 입장에서도 금전적 측면에서나 대외적 이미지 면에서 큰 손실이 아닐 수 없다. 그래서 산업재해를 당한 근로자에게 신속하게 보상이 이루어지도록 하고, 사업주(기업가)에게는 갑작스러운 경제적 부담을 덜어주기 위해 산재보험제도가 도입된 것이다. 회사를 위해 열심히 일하다 재해를 입은 직원의 조속한 업무복귀를 도모하고 기업의 사회적 책무를 다 하기 위해서라도 기업을 경영하는 사업주 역시 산업재해에 대해 기본적인 지식을 알아 둘 필요가 있다.

Simple statistical frequency based analysis, such as Pareto analysis, are widely used in conventional accident analysis. However, due to the dynamic and complex nature of construction works, many factors can simultaneously affect or involve the occurrence of accidents in construction projects. Therefore, the identification of the complex relationship between such factors is important to establish relevant and effective safety management policies and/or programs. In this study, characteristic factors and their relationships' contribution to non-fatal accidents in construction projects are analyzed using the association rule mining (ARM) technique. To this end, a total of 59,202 construction accident data are collected from 2015 to 2019 and the ARM is performed to retrieve specific relationships -named as association rules-among classified factors in the data. Characteristics of the retrieved relationships are analyzed and compared with the results of conventional Pareto analysis. Based on the results, it is found that both fall and trip are notable accident forms having characteristic relations with other factors for non-fatal accidents in construction projects. It is also found that small-scale construction, age of 50s, less than 1 month of working period, and architectural construction are important factors for non-fatal accidents in construction projects.

The converted accident rates that included in Pre-Qualification (PQ) are to evaluate the results of accidents which have occurred. Therefore, it is demanded the development of proactive evaluation contents to evaluate the safety management activities and efforts on construction companies. The purpose of this study is to provide basic data for the establishment of proactive evaluation contents at public construction project in Korea through the collected and analyzed the PQ documentation applied by public agencies in Los Angeles, USA. The results indicated that diverse reactive safety evaluations are implemented to examine accidents which occurred in past projects such as occupational health insurance, regulation violation. And also, when the accidents occurred, it is evaluated the proactive safety management actions such as safety education, accident prevention programs, and safety management plans are reflected on the evaluation. Thus, if proactive safety related evaluation contents are established and reflected in PQ examinations together with diverse existing reactive safety evaluations considering converted accident rates, not only the existing function of converted accident rates can be reinforced but also businesses' active safety management activities can be induced and decreases in the construction industry's accident rate can be expected.

Issues have arisen over the monopoly of housing sales guarantees by the Housing and Urban Guarantee Corporation. If the Ministry of Land, Infrastructure and Transport appoints an additional guarantee institution, there is concern that the property protection between the two parties is insufficient due to excessive competition and the weakening of urban regeneration resources. It argues that housing supply policies for stabilization of the housing market can be smoothly implemented through monopoly projects. This is judged to be an abuse of market dominant position under the Fair Trade Act, and excessive restrictions on pre-sale guarantee requirements may cause delays in business and infringement of property rights of members. First, the establishment of a designation system for market dominant operators of the Fair Trade Commission enables new entry of private guarantee institutions. Second, it is necessary to improve regulations under Article 63 of the Fair Trade Act (consultation on the establishment of laws restricting competition, etc.). Third, through the establishment of the 「Rules on Housing Supply」 under Article 15 (2), the Minister of Land, Infrastructure and Transport can additionally designate a guarantee institution, thereby guaranteeing the right to select a pre-sale guarantee for the business entity. In addition, it is expected that at least one of a number of guarantee insurance companies can be designated to improve the efficiency of the distribution of social benefits, thereby lowering the volatility of housing prices. Listen and suggest.
