This study analyzed the relationship between occupational accidents in the construction industry and business cycle factors. Multiple regression analyses were conducted to achieve the research purpose; additionally, time-varying parameter estimations were performed to interpret the results. The results obtained for the construction industry revealed a statistically significant relationship between occupational accidents and wage increase rate, unemployment, construction starts, and other factors. The wage increase rate plays a role in reducing occupational accidents because efforts are made to prevent accidents owing to the increase in income loss due to accidents and the demand for increased safety levels. The number of construction starts affects occupational accidents with a time lag of 1 to 2 or 4 months; therefore, it is likely to be used as a leading indicator for estimating fatal accidents in the construction industry. This study highlighted the importance of monitoring socioeconomic changes that could affect the working conditions of workers and workplaces, and production activities in the workplace for the effective prevention of occupational accidents. This study also reveals the necessity of developing a method to operate prevention projects flexibly and the seasonality of industrial characteristics, particularly those of the construction industry where the highest number of fatal occupational injuries occur.

This paper presents incentive application strategies and delay prevention strategies as schematic approaches to improve time performance of highway construction contracts. This research recognizes the importance of improving time performance during highway construction. Strategic solutions of the most core issues on time performance incentive contracting are identified. The suggested incentive application strategies develop criteria for applying time classification to projects, for assigning project time classifications to contractors and designers, and for determining appropriate incentive values in A (cost) + B (time cost) and other performance incentive contracts. The suggested delay prevention strategies develop criteria for determining the appropriate subsurface utility engineering (SUE) level and to develop best practices for avoiding utility relocation delays. A schematic approach for each strategy is developed. This paper also introduces current incentive contracting practices in Florida. The researchers obtained the information from experienced persons in the highway construction industry, including key highway contractors, designers, and Department of Transportation (DOT) and Federal Highway Administration (FHWA) personnel. The major focus of this research is to develop strategies and suggest approaches to improve time performance of highway construction contracts. For future study, practical tools to facilitate implementation of the suggested strategies should be developed, so that the criteria, implementation processes, and best practices developed may contribute to the current industry-wide effort to improve time performance.

With regard to industrial accidents, large corporations and public institutions are continuously reducing disasters through systematic management. However, industrial accidents continue to increase in small-scale workplaces. In order to ensure the safety of workers, the government supports the purchasing of industrial accident prevention equitments through financial support projects for small business. However, despite the financial support, the effectiveness of the project is hardly verified. In this study, we analyze the policy effectiveness of the financial support program for industrial accident prevention in a small-scale workplace using the difference-in-difference method. To achieve research purposes, we used the data on the occurrence of industrial accidents, the status of workplaces by year and the data on the status of workplace benefiting from financial support program for the past 10 years. This study is significant in that it analyzed the net effect of financial support programs for disaster reduction in the small business site.

The delay of the completion of the construction project occurs frequently because the origin schedule is affected by numerous factors that contribute to the overall delay in completing the project. But in our country. the dealing with a claim is not sufficient yet by reasons of fairl relation between owner and constructor, cognitive shortage in claim, and such. especially they have make a wrong application of baseless the rule. In this study. we make a rational model ; that includes calculating of dispute costs, and suggest the solution and the prevention for claim by considerating the law followed liquidated damages.

Injury Ratio Survey Regulations(IRS) was introduced to the construction industry in the Republic of Korea since 1992 and brought positive effect on occupational accidents reduction. There were tremendous decrease of injury ratios and enforcing of contractors' safety organizations from the beginning of IRS. In spite of these positive results, there were some negative effects such as contractors' shrinking injury reports to keep good injury ratios since these figures had a great impact on pre-qualification stage of bidding when general contractors were competing for new construction projects. Thus, this study aims to devote on lessening construction injury and elimination of above negative impacts through the quantitative statistic analysis of the effectiveness on the occupational accidents prevention of IRS. According to this assessment, there were decrease of from 6.37% to 44.34% in the accident ratios compared to those of non-IRS groups and decrease of from 3.32% to 83.51 % in the accident ratios compared to those of general industry including the unreported accidents.

Geotube is made of permeable but soil-tight geotextile, hydraulically filled with soil include dredged sand and mud, which has been successfully applied in hydraulic and coastal engineering projects. Ceotube method is getting popular and being used a lot in many countries of the world because of the simplicity of the placement and construction, cost effectiveness and minimum impact on the environment, and enable to store & isolate contaminated materials as obtained by harbor dredging. Laboratory tests and field construction were performed to determine the design methodology and construction procedures. From the results of laboratory and field construction, the retention ratio of solid particle is a minimum 86%. The minimum permeability and the tensile strength of geotextile are $\alpha$ x 10$^{-4}$ cm/sec and 20t/m, respectively Also, based on the environmental test results, it can be concluded that this method does meet the Korean EPA standards.

Prevention of the disasters is the best welfare to workers and it brings the growth and stability of an enterprise, finally uplifts the national competitiveness. Because small-scale businesses do not have safety and health managers, the government provides a wide range of safety and health management supports to small-scale businesses. However despite of this government's effort, the industrial accident rate of small-scale businesses does not decline, which is mainly because the projects are not differentiated according to the risk level of individual business. Therefore, this paper aims to obtain implications concerning a plan to conduct a reliable assessment of education through a safety job assessment, and to build a framework which may improve a technical area through the AHP analysis.
