In construction work, safety accidents often occur in combination with unstable physical and human conditions during preparation and execution of work. In Korea, the accident rate is higher to that of any country in the world. Therefore, it is necessary to take measures by fundamental prescription. In this paper, in the case of construction safety management, we tried to find a reasonable alternative through a questionnaire survey to apply to subcontracting and small-scale construction. In conclusion, workers who are well aware of the task could be able to reduce the accident rate by deploying them as safety management officers after receiving the training.

Many industrial accidents have occurred continuously in the manufacturing industries, construction industries, and service industries of Korea. Fatal accidents have occurred most frequently in the construction industries of Korea. Especially, the trend analysis of the accident rate and fatal accident rate is very important in order to prevent industrial accidents in the construction industries systematically. This paper considers forecasting of the accident rate and fatal accident rate with static and dynamic time series analysis methods in the construction industries. Therefore, this paper describes the optimal accident rate and fatal accident rate by minimization of the sum of square errors (SSE) among regression analysis method (RAM), exponential smoothing method (ESM), double exponential smoothing method (DESM), auto-regressive integrated moving average (ARIMA) model, proposed analytic function model (PAFM), and kalman filtering model (KFM) with existing accident data in construction industries. In this paper, microsoft foundation class (MFC) soft of Visual Studio 2008 was used to predict the accident rate and fatal accident rate. Zero Accident Program developed in this paper is defined as the predicted accident rate and fatal accident rate, the zero accident target time, and the zero accident time based on the achievement probability calculated rationally and practically. The minimum value for minimizing SSE in the construction industries was found in 0.1666 and 1.4579 in the accident rate and fatal accident rate, respectively. Accordingly, RAM and ARIMA model are ideally applied in the accident rate and fatal accident rate, respectively. Finally, the trend analysis of this paper provides decisive information in order to prevent industrial accidents in construction industries very systematically.

This paper provides a basic organizational commitment research for the study was conducted academic research, especially acidic improvements in the construction industry for a job commitment on organizational commitment. In this paper, first results are derived for literature to study and improve productivity and derive a major cause of job involvement of construction companies based on it for critical that the rationale organization.

Full embroidery industrial accidents in recent years has shown a declining trend. But disaster embroidery of domestic construction industry were more than 20,000 deaths per year is about 500 people. The government has introduced a construction site often changing the recruitment of new construction based on health and safety as an alternative to road safety education training yisuje of construction workers, daily work periods short. Certificate of Basic OSH Training in Constructions had also been evaluated as successful by reducing the accident rate problem. It is conducted in private educational institutions has occurred on the friction between workers and employers and training costs are difficult to approach workers in the education standards for such facilities due to the superintendent. Educational institutions are institutions that have been caused by excessive competition lowered levels of education. There is also a lack of evaluation that the training is limited to the basic safety knowledge. These details are brought formal safety education purposes only and is introducing the results of other self jyeotgi difficult to reap the proceeds to good effect. In this study, we propose a plan for improving operational problems and enemy status based on research data presented after the Certificate of Basic OSH Training in Construction.

The scope of this study is the construction conformity assessment system according to the new paradigm of construction management To minimize the differences between domestic and international state, construction Conformity Assessment is subdivided into system certification and product certification. For the former, WASCON(Worldwide Assessment System of Construction Quality Maturity Stage) is applied. For the latter, AQUA(Advanced Quality Assessment System) was developed and adopted to model project for demonstration. Both systems are designed to enable quantified rating, integrated into PQCS(Project Quality Certification), which is an advanced project quality certification system. The construction work observing PQCS will gain quality score on its own quality certificate(Quality mark on construction itself or facilities is also available, if needed or preferred by customers). This Quality Rating System will inspire and encourage any related parties. PQCS score would let supplier/constructor recognize how much themselves are operating effectively and efficiently, offering them the opportunity of redeeming their weaknesses.

In the construction sites, rush (speedy construction) work have recently been overused because of budget reductions by reducing the construction duration after the long-term economic recession and construction business stagnation with institutional change including the instruction of the duration shortening bidding system and the introduction of the post-construction sales system by the Korea Research Institute for Human Settlements. Due to this, negligent accidents have frequently occurred by forcing manpower, equipment, finance, and material procurement and pressing ahead with impractical construction wok at night according to the reduction of construction schedules. Therefore, this paper has the necessity of this study to seek for alternatives to prevent negligent accidents by finding factors related to rush work in the reality that the importance for preventing negligent accidents is more emphasized while they have not been reduced in construction sites.

Recently, industrial accidents rate has been gradually decreasing due to the development of safety management methods, but until now, the accident rate in the construction sector is higher than other industries. Large-scale construction sites are operating systematic safety systems to reduce industrial accidents. However, small and medium sized construction sites do not have systematic safety system and lack safety management ability, so that disaster is not reduced compared with large scale construction site. As a result, disaster prevention technology instruction system has been implemented to reduce the disasters of small and medium scale construction sites. However, in the case of a small construction site less than 2 billion won, there is little decrease in the accident rate, and in some cases, the accident rate increases. After the technical guidance system has been implemented, it is necessary to identify the performance and problems of implementation and to improve its effectiveness. In this study, we suggest the improvement plan to improve the efficiency of the technical guidance system by analyzing the problems and actual conditions of technical guidance operation in small and medium sized construction work sites.

OBJECTIVES: This study aims to review a plan to reduce the shoulder width of a deformed round-trip two-lane highway with low traffic volume. METHODS: Installation of a passing lane on a round-trip two-lane (one-way one-lane) highway, and reduction of a shoulder for a round-trip four-lane highway. RESULTS : It is necessary to establish a design criterion for various highways, because the plan to reduce the lane or shoulder width of a highway with low traffic volume was analyzed to have an economic efficiency of 6.8~7.0%. CONCLUSIONS: It is necessary to seek for a plan to establish a national trunk net early by efficiently using the limited financial resources to cope with the traffic demand elastically.

The safety accident has been repeatedly abolished and resurrected according to the social atmosphere and the issue of the effectiveness of education has been constantly raised. As shown in [Figure 1], the training of the manager, During the ten years of revival due to the amendment of the law in 2007, the accident rate further increased. Industrial accidents often occur in combination with unsafe behavior and unsafe conditions. Unsafe behaviors are indispensable factors in the work that human beings engage in. In order to prevent accidents, it is imperative to establish systems and measures to understand the more obvious causes.

Safety accident in Building construction work in the process of preparation and implementation of the insecure human, material status is often caused by combining the reality is that many things. Accident rate is a similar level in the case of Korea and foreign countries than any country in the measures by the higher fundamental prescription is needed. In this paper, construction safety management of subcontracting work and small construction plan to apply through a survey to reach a sensible alternative. I did In conclusion, the educated workers know well, and so on the work schedule then quickly if safety management personnel in disaster will be able to reduce the rate to a miracle appeared.
