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 the case of a disaster, the damage caused by the disability vulnerability of persons with disabilities is significantly increased, discussing about a problem for the protection of the vulnerable class. However, until now policy, technology and response guidelines for disaster and safety have been focused on the general public. Therefore, it is necessary to develop customized support technology for disaster and safety considering vulnerable characteristics of vulnerable class. Firstly, it is necessary to prepare draft improvement proposal of act and support system related disaster and safety for persons with disabilities and older persons. So, this study was carried out analysis of act, policy and support system on disaster and safety for persons with disabilities and older persons of domestic and overseas in order to draw implication. Furthermore, we established direction for improvement of act and policy on disaster and safety for persons with disabilities based on the analysis, and suggested draft improvement proposal.

Anti-theft safety caps for bolted joints are necessary to ensure the safety of citizens and prevent theft of manholes, bridge guardrails, bulletin boards, subway safety handrails and others. Safety caps enhance the look of bolted joints, avert accidents that involve hitting the head of bolts, hamper them from coming loose by covering the head of bolts. This study focuses on press die design methods and press molding condition setting to resolve bursting and cracks in products, and on molding material selection and heat treatment technologies to boost life extension.

As a result of increasing power demand and concern about power supply shortage in the world, various energy sources without depletion of fossil fuel are installed to electrical network. Above all, nuclear energy can be considered as the most economical energy source to generate electricity. But recently, due to problem of safety which has emerged as a key social issue, additional construction of nuclear power plants is difficult. In order to replace nuclear power, researches on the emergency generator have been actively conducting. This study conducted a survey of public institutions about specification of backup generator system and current states to secure available capacity.

A forklift accident occurs in the logisitcs center. there are many kinds of accidents such as a casualty accident or a minor accident, etc. there are many other causes of accident, including poor visibility and habitual operational mistakes The result of the accident is the phenomenon of cutting, falling, scratching of the product. In the case of minor accidents, workers do not report accidents, so the occurrence of accidents is unknown. The customer receives the goods and then notifies them that they are defective product. After the product is returned, we can see that the forklift accident caused the problem of the product The result of the late response affects the image of the enterprise. In this study, we recognized the need for safety education to prevent accidents and found out which of the education items could raise awareness of safety. As result of the study, disinfection and forklift maneuverability regarding speed were mentioned as the most important items in education.

This paper presents an information system of noise and vibration caused by people as a major source of the environmental problem in residential areas with which people are dissatisfied. Therefore, it is important to monitor the influence of noise and vibration in residential areas. Generally, Geographical Information Systems (GIS) play an important role in noise and vibration mapping. The purpose of this paper is to investigate noise and vibration effects in an urban area and develop a new information network in GIS. Noise and vibration measurements were carried out at a road randomly chosen near INJE University. The obtained values are graphically represented with GIS. Therefore, it is possible to predict noise and vibration in GIS when establishing effective urban plans.

Many firms have applied flexible manufacturing systems as a means of increasing productivity, profitability, and quality. Therefore, the purpose of this paper is to develop the more efficient justification model through an analytical scoring model with the quantitative factors, flexibility factors, and safety factors under uncertainty. In this paper, the three factors for properly comparing and evaluating of flexible manufacturing systems are presented. Especially, this paper has emphasized the flexibility and safety factor; the one consists of organization assessment, process treatment function, products and products quantity, useful life assesment, and software function, the other presents risk assesment, Y2K problem, safety device analysis, total productive management system, safety management. Finally, a normalized scoring model by the new flexibility and safety factors can be used in real fields for flexible manufacturing systems project selection under uncertainty.

With the development of the Korean economy, the number of arson fire has been radically increased and become a huge problem and issue in Korea Society for last several decades. This study is to establish the fire life safety strategy regarding the arson fire through researching domestic fire statistics and performing the computer simulation based on fire scenarios with cutting edge techniques and methods for fire characteristics and fire dynamic. In addition, to design the fire life safety strategy depending on the arson fire pattern, the flow and characteristics of fire flames and smoke are analyzed by the computer modeling.

Safety management cost, US$ one thousand billion has been input to the construction area from 1995 to 2000 but the management quality is still in the developing country level. The above mentioned increase of accident rate are attributed to the generous code regulation, net fit to the sense, varying with time change, but the more fundamental reason of this is no practical construction safety management system, up to now. Hardware-orienting operation for the system could be a main reason of this problem. In this paper, we developed a model for efficent construction safety system. It was found from the case study that the model result in high efficient with low cost.

Estimating the cost of injuries and "accidents" to an organization is very important to figure out about how much well each organization has run his company and how much efficiently he has got the results using a certain amount of the expense for safety. Despite the potential usefulness to management of information as to the cost of a company's "accidents", it is not customary accounting practice to make these data available. Of the two general kinds of costs forced on a company by its occupational injuries and "accidents", the insurance cost and uninsured cost, -the former is by far the easier to find out. But actually, this uninsured cost should be figured out at each company. Authors have designed the generalized model to figure out the above problem costs to establish its efficient safety control. One construction company has been a pilot for this study. It is found that efficient safety control cost should be 1.2%~l.3% of total selling amount by analyzing actual data for three years.g actual data for three years.
