Since 1990 in South Korea, the considerable concern for the safety of construction sights has been increased due to serious accidents. There have been numerous big improvements in preventing the accidents by strengthening legal enforcement and by continuing to emphasize the safety management. Further, the safety standards and criteria for temporary constructional work have been enacted and established in order to maintain safe work environments in temporary construction and structure settings. However, the death rate from fall accidents is still high in the temporary constructional and structural settings in comparison to other work places in construction. According to the analysis of accidents in the field of construction between 2000 and 2007, the death rate from fall accidents in the temporary constructional settings was highest. In addition, there have been more fall accidents in the work setting by small or medium construction enterprises rather than large enterprises due to the relative lack of the safety management. Thus, in this study, the analysis of the causes of fall accidents in the temporary constructional and structural settings between 2000 and 2007 was conducted. Moreover, a survey study was carried out in order to investigate further causes based on the analysis. Finally, this study was also conducted in order to provide basic information and knowledge about the prevention of future accidents.

Scaffold is the most commonly used equipment in various types of construction works. Since various types of construction works use the same scaffold equipment, it becomes more difficult to be controlled and managed, thus resulting hazard frequently. According to the information announced in July 2012 by Council of Labor Affairs Executive Yan, the site collapse or incomplete anti-falling protection has led the site to accident frequently, and this is the main reason that causes construction industry occupational disasters. The labor death occupational hazard ratio rises up to 13% in scaffold activity, and the Council of Labor Affairs Executive Yan has showed that the death ratio is higher when using the scaffold in construction site, the total number of death has reached to 139 from 2005 to 2010. In order to ensure the safety of scaffold user, this study tends to build a wireless sensor monitoring system to detect the reliability and safety of the scaffold. The wireless sensor technique applies in this study is different with the traditional monitoring technique which is limited with wired monitoring. Wireless sensor technique does not need wire, it just needs to consider the power supply for establishing the network and receiving stable information, and it can become a monitoring system. In addition, this study also integrates strain gauge technique in this scaffold monitoring system, to develop a real-time monitoring data transfer mechanism and replace the traditional wired single project monitoring equipment. This study hopes to build a scaffold collapse monitoring system to effectively monitor the safety of the scaffold as well as provide the timesaving installation, low-cost and portable features.

The construction industry has the highest death rate related to safety accidents of any industry. Furthermore, in contrast to other industries, where the death rate related to safety accidents has been steadily declining, both the death toll and the number of accidents in the construction industry have been on the rise. Construction accidents occur when various risks increase in an intertwined way to reach a tipping point; a moment when such factors cannot be tolerated any longer Conventional safety management methods have restrictions in terms of their ability to fully prevent all types of safety accidents. This research considers ways in which USN technology can be applied to safety management on a construction site, and derives a method of applying USN technology for safety management monitoring. The tasks related to safety management on construction sites, as well as the occurrence of accidents, are first analyzed. By analyzing the characteristics of construction accidents, the factors that must be a priority and the factors that can be a lower priority are derived. Finally, the configuration of a monitoring system for safety management on a construction site to which USN technology is applied is presented. It is expected that safety accidents can be prevented from occurring on construction sites by applying this cutting-edge USN technology.

The construction environment has been declared as a hazard prone area due to high number of accident and death. The study aims to identify influential factors that contribute to poor safety practices and its consequences on construction workers in Cape Coast Metropolis. Seventy respondents were taken as the sample size for the study. Descriptive analysis was used to analyze the data obtained from the field. Findings show that poor site management, working without safety gadgets, failure to use their Personal Protective Equipment (PPE) and negligence of workers were the main causes of accidents on sites. Poor site management had the highest ranking among the seven variables. Effects of poor safety practices on building construction site and delays in work execution were due to injury of workers, extra cost due to payment of compensation to injured victims, not motivated due to injury of worker and declined reputation of firm. Management team should motivate workers for safe work done, provide adequate PPE for their workers on site and have documented health and safety policy on site. Site authorities and management team should be on site regularly to ensure proper safety practices on construction site.

Many construction accidents can be lead to a death occurring at construction sites. These are considerably due to potentially-hazardous equipment and machine or unexpected collapsion at earth work due to land slide and so on. Almost 50% of the total death and injury, occurred in construction sites in 2015. 66% of those serious accidents are due to falling occurring from construction sites when they work. Therefore, causes and recommendations of each accident should be deeply thought and analysed The indirect causes are directly related to safe consciousness of the construction workers. Actually, their safety consciousness are not high, even very low, it is thought. Questionnaire survey sheets have been distributed to Seoul, Incheon, and Gyunggi-Do area, first. And then, the authors have collected those directly at sites, in order to increase collection rate of the sheets. The totally, collected sheets are 295 sheets. And, they are analysed using SPSS version 19 package program. Workers internal consciousness has been investigated and reviewed and analysed by statistical method such as frequency rate, crossed, and correlated analysis. And finally the conclusions for the above analyses are as follows; Heavy weight worth a crew of more than two workers should be necessarily considered for the advanced safety plan and needed for making a highly potential hazard group at construction sites. Safety consciousness, earing p.p.e, workman ship should be mainly considered for investing safety costs with an aspect of human factor.

Construction fall accidents have been investigated by many researchers. Construction workers are prone to fall when elevations of the construction site is high. And falls are the most fatal accidents: it can be directly linked to the death. Construction fall accidents might be reduced by predetermining several areas which are highly probable to have fall accidents and by controlling such areas until the completion of the building construction. In this paper, a fall prevention system is suggested which can identify the areas where the focus on fall protection is perhaps most needed from the process characteristics. Main methodologies for this research are summarized as follows: 1. A data base on elements and types of falls is constructed from the data analysis of last 10 years fall accidents history. 2. Guideline is derived by identifying the highly probable areas of fall accidents with respect to the specific construction process. 3. Developed system is verified by applying the system to construction sites. 4. Finally a fall prevention system is suggested by utilizing the fall accidents data.

The purpose of this study is to identify the expression methods of uncanny images shown in contemporary fashion through the visual expression methods of plastic arts. The study results are as following. First, there is a concept-forming element of 'The return of Repressed', which is a psychological mechanism for generating uncanny sets to the component of 'repression' and 'return'. 'Repression' herein consisted of 'unconsciousness', 'the other', and 'anxiety', while the return was composed of 'trauma' and 'repetition compulsion'. Second, there are visual expression methods of the uncanny in contemporary art. The subject of 'repressed things' was expressed as grotesque and having a terrible look. 'Fragmented body' was analyzed as 'dismantling' by mutilation, 'combination' placing cut body parts in other places, and 'damage' suffering from an illness or accident. 'Fear of death' was shown as 'anatomy' reminiscent of death and 'iconography of death' meaning return of the dead. 'Post-human' was a surrealistic being such as a monster and mechanized human, and was analyzed as 'gene variation' and 'cyborg'. Third, the methods of visual expression of the uncanny reflected on contemporary fashion was analyzed as 'fragmented body', 'fear of death', and 'post-human'. 'Fragmented body' appeared as the object reminiscent of the fragmented body, 'dismantling and combination of the body', and 'damage of the body' through the distortion of the clothing construction principle. 'Fear of death' visualized the characteristic elements of the subject reminiscent of death as 'iconography of death' and 'symbolic object of death' through the motif. 'Post-human' was the description of the subject beyond the body's function and form, and was shown as 'gene variation' and 'cyborg'.
