The number of the lifts installed and used in Korea totals up to 526,676 units as of the end of December 2014, due to the development and urbanization of this country. Since the lift is one of the convenience facilities and especially a kind of essential transportation facilities used by a majority of passengers everyday, it is necessarily required to manage the lift safety. Therefore, this study aims to determine the 5 factors(kinds of lifts, ages of victims, causes of accidents, seasons in accidents, usages of buildings) affecting the types(caught in, trip over, falling, collision) and the injury levels(death, serious injury, minor injury) of the lift accidents based on the analysis of the total victims of 1,514 people due to the 1,146 accidents which have occurred for the past 15 years, and to find the frequency and ratio of each factor in the accidents, and to make a correlation among the factors. As the result of the analysis, it shows that there exists a statistically significant correlation among the factors.

The more the lift environment eastern idea, culture, factory automation system and information technology complicates, the more the various human error brings about. It brings about all kind of accidents and occupational diseases. Also the death and sickness or injury by psychological stress among the human error has increased every year. Therefore this paper describes the Korean lift change unit model through statistical testing with the proposed life change unit factors on the married workers living the middle area. The proposed model can be simply used in order to minimize the industrial accident and human error in real fields. Finally, the result will be helpful for the better safety management.

As buildings become higher, larger, and more complex, safety issues for construction workers working at such environments become more important. We analyzed 140 critical accident cases reported to the KOSHA(Korea Occupational Safety & Health Agency) for construction cranes and lifts by types of cranes and by patterns of accidents and causes. By finding out the accident's types and causes, we expect to develop an efficient measure for preventing similar accidents in the near future. The cases will be studied further and reexamined using the FMEA(Failure Mode and Effect Analysis) as a quantitative analysis method.

According to the statistics, occupational fatal injuries by the fork lifts were about 30 per year in whole industrial. Fork lifts are widely used in various parts of industries to improve the efficiency of the work. In this study, the current regulations to be adequate in industrial site have to be renew in order to prevent the fatal injuries by the fork lifts. Fatal injury analysis were conducted with several accident cases by the fork lifts. For each accident, the causes of the injuries were examined and proper safety measures were proposed. In this study, the fork lift showed a high fatality rate in industrial accidents and no detailed cause analysis of fatal accidents was conducted in terms of unsafe acts or conditions. First, fork lifts were the highest of the machines caused the accidents. In order to prevent fatal injuries by the fork lifts, the tarket was manufacturing industry. Second, the order of the cause of cognitive engineering agenda in the manufacture industrial was visibility, responsibility and affordance, and revision of acts was proposed. Third, there was not a lots of different points of human error between occurrence types and business sizes. Forth, number of fatalities by the attacker was more than by the inducer.

The DC part of the DC microgrid power conversion system uses capacitors for buffers of charge and discharge energy for smoothing voltage and plays important roles such as high frequency component absorption, power balancing, and voltage ripple reduction. The capacitor uses an aluminum electrolytic capacitor, which has advantages of capacity, low price, and relatively fast charging/discharging characteristics. Aluminum electrolytic capacitors(AEC) have previous advantages, but over time, the capacity of the capacitors decreases due to deterioration and an increase in internal temperature, resulting in a decrease in use efficiency or an accident such as steam extraction due to electrolyte evaporation. It is necessary to take measures to prevent accidents because the failure diagnosis and detection of such capacitors are a very important part of the long-term operation, safety of use, and reliability of the power conversion system because the failure of the capacitor leads to not only a single problem but also a short circuit accident of the power conversion system.

Although automotive safety technologies have been developed steadily, the efforts for pedestrian protection still seems to be insufficient. In a car-pedestrian accident, the structures such as the engine under a hood, the lower part of a windshield and the A-pillar are the major causes of fatal pedestrian injuries. Recently, there have been several studies on the active safety system to reduce the pedestrian injuries. The safety system consists of an active hood lift system and a pedestrian airbag. In this research, the safety performance of the active hood lift system and the pedestrian airbag is investigated by using the finite element method. The finite element model of the system is set up based on the head impact test, and the impact analyses are performed. The necessity and the usefulness of the safety system are verified.

The Serial Securities and the Social Welfare, as the national policy aimed at securing generals' lives, are the policies or systems for the stabilization in lift; especially of law-incomers and workers, for which the povernment has to establish the Social Security System. No wonder the Social Insurance System is a part of the Social Security System and the most important. The Social Insurance System, along with Public Assistance, is underlying the Social Security System. Social Security System includes medical insurance, industrial accident Compensation insurance, national pention insurance and employment insurance. The study is on 'The Oriental Medical Insurance and the Industrial Accident Compensation in the Social Security System' . The rate of industrial accident in Korea marks the highest rank in the world. for laborer, industrial accident do not merely mean the loss of health but the question of the right to live in terms of their loss of opportunity of life. The industrial accident compensation system should be established as the es post facto remedy system to guarantee the injured worker and his/her family's life. The oriental medical insurance system which began to operate in 1987 in Korea is based on unionism and divided into 3 parts; one part for the worker, a second part for the community inhabitants, and a third part for the public service personnel and private school personnel. Today the medical problem must be the most important social assignment to be considered. The medical system of contemporary industrial society has began greatly stood out in relief as a part of social welfare not emphasized on gainings of physicians. Accordingly systematization of the oriental medical insurance was strongly Pursued and it was developed to to the extent of entire nation insurance. Though the history of it is very short, most of the people are getting benefit from the insurance system by the social security system method. This study develops the Oriental Medical Insurance, the Workmen's Accident Compensation Insurance, the Pension System in relation to the industrial accident compensation of Employees, along with the ideas and principles of social insurance.

Construction machinery has been utilized to carry out construction works effectively. Using construction machinery enables a builder to reduce the time and the cost needed for the construction, but the fatal accident caused by it has been increased. This study is intended to identify risk magnitude of accident by kind of construction machinery through interviews with experts. Construction machineries surveyed in this research are excavator, tower crane, lift, mobile crane and forklift, those are the machinery which accident occurs more often than the other machinery. To evaluate the risk of the accidents identified, risk category was determined according to the US DOD system safety program (MIL-STD-882B) considering the risk degree and intensity. As a result, accident occurred in the process of material transport & handling was found to be the most dangerous. On the other hand, the accidents caused by the defective machinery and the poor safety gear were considered to be less dangerous relatively. The risk category by type of construction machinery suggested in this study is expected to provide the basic data in developing the safety guidance for construction project.
