The continuing urbanization and industrialization around the world has required a large amount of power. Therefore, construction of major infrastructure, including nuclear power plants in coastal areas, has accelerated. In addition, the intensity of natural disasters is increasing due to global warming and abnormal climate phenomena. Natural disasters are difficult to predict in terms of occurrence, location, and scale, resulting in human casualties and property damage. For these reasons, the disaster scale and damage estimation in coastal areas have become important issues. The present study examined the predictable weather data and regional ratings and developed estimating functions for wind wave damage based on the disaster statistics in the southern areas. The results of the present study are expected to help disaster management in advance of the wind wave damage. The NRMSE was used for verification. The accuracy of the NRMSE results ranged from 1.61% to 21.73%.

If industrial safety statistics are analyzed, among the total of 2,114 dead people from industrial disasters in 2011, construction workers took 29.4% with 621. The construction industry makes a lot of efforts to reduce the death toll. However, since the measures are not from the analysis of root causes but from superficial countermeasure plans near general matters, it is in a situation that the actual effectiveness is marginal. Therefore, in this paper, improvement measures were intended to be prepared in order to reduce accidents, by inspecting safety control systems of target companies with high accident rates among major construction firms and extracting overall problems of them.

Recently, a series of massive earthquakes have been occurred northeast Asia and there has also been constant sensible earthquakes in South Korea. Particularly, after diagnosing educational facilities with Sichuan earthquake momentum, remodeling construction of old educational facilities and buildings which were not designed not to resist earthquake are actively underway. Remodeling construction sites, however, are mostly small construction sites which consist of less than 30 full-time laborers, where a number of deaths from a fall occur by improper uses of protective gear. Therefore, to reduce the disaster from a fall caused by inadequate uses of protective gear in domestic small construction sites such as those for remodeling, this study conducts research into ways of decreasing accident rates by suggesting providing and administering protective gear as a national project so that donning protective gear is activated.

The Korean society, which faces a new issue of foreign labores, is actively conducing safety consciousness of foreign labors. Foreign labors of domestic industry reached about 360,000 recently. it has become the essential resources to fill up insufficient labor in construction industry. Although most foreign labors participate in safety education well and understand its object, some foreign labors have negative recognition of it. Some foreign labors well comprehend the importance of safety facilities but think those unnecessary. Based on these results, this research pointed out the need to review training manuals, the development of educational programs, improvement of educational facilities to improve safety education of construction, and finally to discussed these issues.

Construction victims have increased year by year. Disaster proportion is also increasing continuously. Looking over the causes of disasters by each type of work, fall from working platform indicate the highest rate above all so that it is urgently required to set up safety measures. This study is to grasp the present status of construction accidents, to identify areal characteristics of the top 20% accidents on the basis of working platforms with the highest accident rate, to grasp the causes of accidents after their analyses, and to present methods to reduce casualties related to working platforms. As measures to reduce construction disasters, this study proposes to improve safety management and training on working platforms, to complement safety regulations, and to better performance including the development and expansion of certified products suitable for safety regulations.

Construction companies economic to lighten the restrictions on safety education and training due to the domestic recession as long as the global downturn. With this, the Korean government lightened that restrictions, but the incidents are being sharply increased nowadays. The construction industry is more hazardous than any others, so, they insist to reinforce the training for incidents prevention, but it is prone to be disregarded at the subcontractors of the bigger construction companies due to their financial problems. According to these matters, this study hereby surveyed regarding their suggestions for the improvements of the training concepts through questionnaires below.

In terms of deregulation requests from business, incidents at construction sites are rapidly increasing after reducing the regular safety training hours. Especially, to prevent incidents through safety trainings for construction site workers, who have lots of hazardous tasks than general manufacturing, is not only to protect property of both the companies and the country but also to increase their profits. That is why there are loud voices regarding that the safety training is a core mandatory to prevent industrial incidents. But, most companies, as soon as the deregulation for safety training is implemented, mitigated conducting safety trainings to prevent incidents. With this, theincidents are currently to be increased and caught in a vicious circle of many incidents at the smaller companies because of their absentmindedness regarding safety training due to their poorness as subcontractors of major companies, comparing to major companies. This study explains that incident factors are roughly divided into technical factor, managerial factor, and educational factor. And, we confirmed that the educational factor led by deficiency safety awareness and knowledge was the major factor.

Death disaster among the disasters in construction field is mainly occurred by crash, and the work plate is the main objects causing crash. This study was performed by interview with workers in construction field to evaluate the consciousness on safety and to analyze the type of use and the state. Finally the problems while using work plate were appeared with its requirements for the improved use. Based on the results from this study, amendments were proposed for some parts of regulation related, and further four types of development on the safe work plate were presented. It is expected that the safer construction environment could be composed by using the results.

More often than not, cost claims which are legitimately due and entitled to the contractor for works done, or for loss and expense incurred arising from disruption, prolongation and delay, are surprising not successfully recovered, whether in whole or in part, or none at all. One of the main reasons attributing to such scenario, is due to either the contractor, employer or the consultants and their poor understanding of and adherence to established and proper contractual rubric that is embodied in the building construction contract for the works. This paper explores some such pitfalls that could very well spell the ultimate financial disaster for many contractors, and highlights salient and essential intimations that contractors and consultants should watch out for.

Looking at recent construction cases at winter construction sites, there is a risk that heat sources such as kerosene fans and fossil fuels (brown coal, molded carbon) used in concrete will cure rapidly, so in situations where further curing is impossible after formwork removal, the outer wall and the entire slab are exposed to rapid external deterioration, resulting in delays in concrete strength expression and until collapse accidents. In this study, we applied kerosene fans and tropical circulating electric heat fans mainly used as curing heat sources at construction sites, comparative analysis. also verified the performance of structures during concrete curing due to thermal convention / circulation performance, concrete demand strength expression, and implementation of electric heat fans by heavy disaster methods.
