The purpose of this study is to analyze the influence of the economic and workforce factors on the annual number of occupational accident fatalities occurring at the construction sites. The considered variables of the economic factor are the amount of economic losses caused by industrial accidents, the GDP, and the total monthly wage for each economically active population. And, the variables related to the workforce factor are the number of economically active population, the number of female economically active population, and the number of labor union members. The multiple regression analysis was conducted to determine the effect of two factors on the total number of occupational fatalities in the construction industry. The results show that GDP among considered variables in the economic factor had a statistically significant negative relationship with the number of the construction accident fatalities in the construction industry. Among variables related to the workforce factor, economically active population showed a statistically significant negative relationship with the number of the construction accident fatalities.

The purpose of this study is to determine whether the variables of the agency factors affected the number of occupational fatalities in the construction industry in order to determine whether there is a relationship between the number of occupational fatalities occurring at the construction sites and the agency. The considered agencies are KOSHA (Korea Occupational Safety and Health Agency) and MOEL (Ministry of Employment and Labor). The variables of two agency factors are classified as follows: the variables of two agency factors are the number of employees, budget amounts, technical support and guidance for construction sites of KOSHA, and the number of labor inspectors, the number of inspection and oversight workplace, the number of criminally punished construction sites and fines levied on them in the industrial accident prevention departments of Regional Employment and Labor Office. The multiple regression analysis was conducted to determine the effect of two agency factors on the total number of occupational fatalities in the construction industry. The policy implications derived from this study are that, in order to reduce the fatalities of construction sites by KOSHA, the appropriate level of increased budget for KOSHA must be secured every year. In addition, the amount of fines levied on construction sites by the labor inspector in the industrial accident prevention departments of Regional Employment and Labor Office reduces the occupational fatalities at the construction sites.

우리나라의 도로는 종류별로 관리주체가 서로 다르다. 고속국도는 한국도로공사, 일반국도는 건설교통부, 지방도는 광역자치단체, 시 군도는 기초자치단체에서 건설 관리 및 운영 책임을 맡고 있다. 본 연구에서는 이렇듯 관리주체가 다른 우리나라의 도로에서 발생하고 있는 교통사고발생 추세를 도로종류별로 분석하는데 목적이 있다. 이를 위해 과거로부터 축적된 도로종류별 교통사고건수, 사망자수, 부상자수의 자료를 기반으로 사고위험을 단순건수, 도로연장 당 건수, 그리고 대 km당 건수로 비교하였다. 그 결과 단순 건수에 의한 비교에서는 도시부 도로가 전 부문에서 가장 위험하고 고속국도는 전 부문에서 가장 안전한 것으로 분석되었다. 그러나 1km당 발생건수는 일반국도가 가장 위험하고 지방도가 가장 안전한 것으로 분석되었다. 교통사고 발생률을 가장 객관적으로 비교할 수 있는 지표인 10만 차량 대 km당 비교에서는 일반국도가 가장 위험하고, 고속국도가 상대적으로 안전한 것으로 분석되었다. 한편, 도로종류별 사망자수 추세를 설명하는 시계열 분석모형을 개발한 결과 고속국도, 지방도, 도시부도로의 경우 AR(1)모형이 추세를 잘 설명 할 수 있는 것으로 분석되었고, 일반국도의 경우 ARIMA(2, 3, 0)모형이 추세를 설명할 수 있는 것으로 분석되었다. 이러한 모형은 장래 교통안전계획의 목표치를 수립하거나 평가하는데 근거자료로 활용될 수 있을 것으로 보인다.

Proportion of falling from height accident at construction work accounts for more than 40%, and the number of injuries is getting increased. So without considering falling from height, we can say that it's hard to achieve our goal(accident prevention). Another critical point that we have to think about theses days is the fact that construction workers are getting older. To be specific, the number of workers who are above 50 years old accounts for 65.6% among the fatalities(2007~2011, KOSHA inspection). Accordingly, to effectively prevent construction accedents, especially falls from height, we need to focus on motion analysis of older construction workers and then make suitable measures for growing accident rates at construction work.

According to the statistics, occupational fatal injuries by mobile cranes were about 12 per year in whole industrial. Mobile cranes are widely used in various parts of industries to improve the efficiency of the work. However considerable number of fatal injuries happen each year during the operation of the machines. In this study, the current regulations to be adequate in industrial site have to be renew in order to prevent the fatal injuries by mobile cranes. Fatal injury analyses were conducted with several accident cases by the mobile cranes. For each accident, the causes of the injuries were examined and proper safety measures were proposed. In this study, the mobile crane showed a high fatality rate in industrial accidents and no detailed cause analysis of fatal accidents was conducted in terms of unsafe acts or conditions. This study proposed a revision of the standard guideline as an accident prevention measures through in-depth analysis of fatal accidents. First, among the mainly five machines caused the accidents, mobile crane was higher for the second showed 0.6% for number of fatalities compared to number of mobil cranes and for the third showed 11% for number of fatalities compared to number of injuries. Second, main cause of cognitive engineering agenda was visibility, responsibility, affordance. As the measures to prevent accidents before starting operation, alternative revision for the fool proof including visibility, responsibility, affordance etc. for the fool proof measures was proposed. Third, alternative revision as cognitive accident prevention for the fail safe measures was proposed.

According to 'The Analysis of Industrial Accidents in 2016' by Ministry of Employment and Labor, the number of deaths caused by accidents in the construction field is 391, accounting for 47% of 826 industrial fatalities in all industries. The breakdown of the 391 fatalities of the construction industry shows that 'struck by an object' accident had 30 fatalities, the 3rd in frequency following falling (235) and crashing (32) accidents. This study aims to explore ways to reduce the 'struck by an object' accident with emphasis on safety education and certificate system for rigging and slinging works. This study reviews literature on rigging and slinging works and analyzes 'struck by an object' accidents. The rules and regulation on the rigging and slinging works are also reviewed both for Korea and other countries with best practices in construction safety such as Singapore, Japan, U.K., and U.S. The rigging and slinging certificate systems of those countries are also reviewed to find any advantage in the construction safety management. In addition, a pilot rigging and slinging certificate system was executed in one of domestic construction site followed by two surveys: one on the riggers who participated in the pilot operation and the other on general managers in domestic construction sites. Based on the analysis of the 'struck by an object' accidents and pilot operation, this study proposes a rigging and slinging certificate system to reduce accidents, enhancing safety condition of construction sites. The certificate system was proposed in a way to accommodate working practice of construction sites. Depending on rigging careers and a crane load capacity, riggers are eligible to apply either basic or master certificate which makes difference in the level of rigging works. The safety condition of rigging and slinging work could be substantially enhanced if workers, managers, supervisors, administrators, and policy makers work together consistently.

In the mid of the December 2019, the virus has been started to spread from China namely Corona virus. It causes fatalities globally and WHO has been declared as pandemic in the whole world. There are different methods which can fit such types of values which obtain peak and get flattened by the time. The main aim of the paper is to find the best or nearly appropriate modeling of such data. The three different models has been deployed for the fitting of the data of Coronavirus confirmed patients in Pakistan till the date of 20^th November 2020. In this paper, we have conducted analysis based on data obtained from National Institute of Health (NIH) Islamabad and produced a forecast of COVID-19 confirmed cases as well as the number of deaths and recoveries in Pakistan using the Logistic model, Gompertz model and Auto-Regressive Integrated Moving Average Model (ARIMA) model. The fitted models revealed high exponential growth in the number of confirmed cases, deaths and recoveries in Pakistan.
