재해자수를 상시근로자수로 나눈 값이 재해율이다. 건설공사의 경우 공사실적과 노무비율을 기준으로 하여 상시근로자수를 추정하고 이를 이용하여 재해율을 산정하므로 재해율의 정확도가 낮아질 수 있다. 또한 현행 재해율 산정기준은 공사유형간의 특성을 반영하고 있지 않다. 본 연구는 공사종류별 특성을 고려한 재해율 보완방식을 제시하는 것으로 목적으로 진행하였으며, 지난 18년간의 공사실적 및 재해건수 통계자료를 바탕으로 상관분석과 선형회귀분석, 중회귀분석 등을 실시하여 공사유형과 재해유형간의 관계를 나타내는 회귀식을 도출하였다. 본 연구에서 제시한 수식은 기존의 건설공사 재해율의 단점을 보완하여 재해의 증감 및 예년대비 재해율의 높고낮음을 판단하는 보조지표로서의 활용이 가능할 것으로 기대된다.

Depending on the growth of the construction industry, size of construction sites are becoming enlarged, and construction work is becoming diversified as well. However, this increases risks of safety accidents. In order to alleviate this problem, some large construction companies have implemented a Safety Patrol Management System (SPMS) in order to reduce accidents on construction sites. Aimed at the construction sites where SPMS has been applied, the purpose of this research is to calculate the proper number of SPMS safety mangers by comparing and contrasting the number of safety managers per person for each site with different sizes and the converted accident ratio. In addition, we also aim to calculate the adequate amount of SPMS safety management costs compared to the total amount of construction expenses required once SPMS is introduced.

In consideration of current circumstances which management activities for safety performance on construction sites are mostly controlled by safety personnel, it is necessary to maintain qualified safety personnel those who are experienced and have adequate ability. This is a major factor in order to prevent any of work related incident in the construction site. However, the existing standard which enforces certain number of safety personnel in the construction site aligning with respective contract amount could lead to difficulties for proactive safety management. So, it is required to get improvement on the existing standard. In nominating the proper number of safety personnel, it would be more efficient to consider the level of risk for characteristic of work itself and the total number of manpower mobilized in respective construction work, rather than to follow the existing standard of manpower ratio as per the contract amount. Hence, this study aims to propose several plans which enable to improve the existing standard for assignment of safety personnel on construction sites.

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 construction arbitration field has developed considerably since the latter half of the 1990s. Through analysis of construction arbitration cases taken up by KCAB, this paper intends to show the present condition and the improvement direction of construction arbitration in Korea. The number of construction arbitration cases filed at KCAB has been increasing rapidly after 1997, but recently the rate of increase has tended to decline. From 2000 to 2003 the number of arbitration cases increased 23％ each year, on average, but in 2003 the increase was only 7.6％. In the very beginning, public construction claims made up the majority of all construction cases, however, civil construction claims are increasing gradually. The arbitration amount in the construction field is very high, owing to public construction claims. For example, the arbitration amount per case was 5 billion won, on average,. in the public construction field. It is shown that the claimants of arbitration are mostly constructors and the main reasons for making claims are to demand payment for construction and payment for additional work. KCAB investigated the performance status of arbitration awards. The voluntary performance rate for awards in construction arbitration is nearly 80％ and in 11％, a suit was filed to appeal the arbitration award. In spite of the development of construction arbitration, some improvements are requested. There have been arguments about the effectiveness of selective arbitration agreement in the General Terms of Construction Contract. This has caused a decrease in arbitration cases, so improvements in this dispute settlement clause need to be made. Enforcement of arbitration awards is granted by the judgment of a court. Resulting from this, appeals for arbitration awards are not allowed, however, up to three appeals for the enforcement of awards are allowed in court. As such, the enforcement system for arbitration awards needs to be improved and simplified.

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.

The number of defect disputes occurring in apartment houses is increasing year by year, and among them, disputes caused by defects in tiles account for 28.2% of the total, which is an important defect in tiles. A representative tile defect in the defect dispute is the lack of tile backfill. Another dispute occurred that the standards for each organization are different as the 100% standard of the Ministry of Land, Infrastructure and Transport's building construction standard and 80% standard of the Architectural Institute of Korea's Building Technology Guidelines. In this study, it was analyzed the relationship between the amount of tile backfill and the amount of tile defects based on 100 defect litigation court appraisal documents. It was observed that the amount of defect in tile works tended to decrease as the amount of tile backfill increased. By presenting an appropriate amount of mortar to fill behind tiles in a defect dispute, the effect of reducing the defect dispute can be expected.
