To assess the status of safety accidents, authors reviewed and analysed the records of safety accidents of a welding material manufacturing factory at Pohang city from January 1989 to December 1993. The results are; 1. The total incidence of safety accidents was 295 spells for five years. 2. Average age of workers with accident was 35.7 years. Average duration of employment was 6.2 years and the duration of employment increased as the year increased. 3. There was no statistical significance on season, month, weekday and time by year in the incidence of safety accidents. The most frequent part of body injured was upper extremities and the most frequent type of injury was abrasion. 4. Mean admission rate of safety accidents was 12.6% and the ratio of treated spells as occupational injury was 7.8%. 5. The most frequent cause of injury was worker's mistake and the most frequent action for the prevention of further accidents was safety education. 6. The incidence rate of safety accidents on 1993 was 116.2 spells per 1,000 persons. Above results suggest that to prevent safety accidents, safety education should be done continuously, the environmental and human factors were controlled and more exact reporting system of safety accidents was needed.

Background & Objectives: International radiation protection committee recognized the importance of radiation protection from medical practices because the exposure to the radiation in medical practice is higher than any other exposure. The factors on knowledge, attitude and practice of radiation safety of the medical workers engaged in radiation were analyzed in order to improve radiation safety technology. Method: Questionnaires were used for 1200 radiation workers in medical institution from July 23 through September 4 and collected for analysis. Results: Different level of safety measures were practiced by age, marital status, career, and medical facility. The difference was statistically significant. Higher levels of safety measures were practiced in the age group of 50s and married persons. The workers who have more than 20 years experience have higher level of safety measures. The workers of health centers have higher level of safety measures to compare with other workers. The factors which give more concerns on safety practice were self efficacy, practice and knowledge in order. Conclusion: Safety conscious operators should get additional education program to maintain higher level of safety. The operators who do not have much safety concern should be intensive training program for self efficacy and safety.

Clinical research is a necessity, not an option, for developing better and new medicines and therapeutic modalities. But in the course of clinical research, there are rules and guidelines that should be followed to ensure the due respect for persons, beneficence, and justice for persons who voluntarily participate in the research as described in the Belmont Report. Good Clinical Practice (GCP) is an "international scientific and ethical quality standard for designing, conducting, recording, and reporting" clinical trials. The main purposes of GCP would be to protect rights, safety, and well-being of trial subjects, in compliance with the principles of Declaration of Helsinki, and to assure that the data obtained from clinical trials are credible. In order to achieve these, investigators must be fully aware of the meanings as well as actual procedures involved in the research and should make the best effort to comply with GCP. For those individuals who belong to vulnerable populations, such as neonates, in addition to the general principles of GCP, further measures to ensure added protection should be implemented. It is our duty to develop and provide better care through clinical research even for neonates. But in doing so, we have to make sure that the importance of protecting the rights, safety, and well-being of the subjects supersede the interests of science and society.

This study was conducted to develop a dummy in an environment similar to the human body, to prepare a standard for evaluation and to present the process of the production in order to evaluate the performance of the robot that can detect the persons needing rescue in a confined space, who are difficult for fire-fighting officials to rescue in case of fire and disaster. As a result, a standard for evaluation was developed and standardized into four parts 'Normal,' 'Risk Stage 1,' 'Risk Stage 2' and 'Risk Stage 3'based on the number of breath cycles, carbon dioxide concentration, core temperature and criteria for hearing to recognize the voice. In addition, in order to produce a dummy, fever, breathing capacity and voice output function were compared and analyzed. This study has significance that it built up basic data of the method of producing the actual dummy, by presenting characteristics and controlling methods using the waterproof insulation heating coil for the function, solenoid valve for the consecutive output of breathing capacity and USB program sound board for voice output.

The objective of this study was to understand which type of fire hose should be placed in indoor fireplug box upon analyzing the preparation time between rack-type fire hose and reel-type one. With respect to the type of hose, rack-type stacking method was used and hose preparation time was measured with 5 times of repeat test, separating men and women. Study results reveal that preparation time of reel-type fire hose took longer than that of rack-type one in both men and women. For both rack-type hose and reel-type hose, preparation time by two persons took shorter than that by one man. Also, preparation time by three persons took shorted than that by two women. Preparation time for both rack-type hose and reel-type one by men took shorter than that by women. In summary, it was confirmed that rack-type hose could be prepared within shorter time than reel-type one. Since the size of drum set in the reel-type fire hose is relatively small, it had some difficulty in preparation of fire hose timely.

Because ships are very isolated and independent objects when sailing on the ocean, if a fire and smoke occurs, nobody can be sure to escape safely from ship at the moment. On the focus of the relationship between the sight transmissivity by fire smoke density and the life safety, this study performs simulations and experiments, respectively. To evaluate the theoretical evacuation time, CFAST software which is known as a 2 zone model analysis tool is used, and the result is 54 seconds from ECR(Engine Control Room) exit to upper deck exit and 34 seconds from bosun store to upper deck exit. And totally 12 types of experiments are performed with other 10 persons per experiment. As the result, it is cleared that the low sight transmissivity leads to the low life safety and the obstruction which can be happen unexpectedly on the evacuation way on fire makes it worse. At the condition of the smoke density 0%, over 90% people arrive at upper deck exit safely. But with the transmissivity of 8%, 70%(from ECR) and 30%(from bosun store) among experiment persons of each can survive, and with same density and unexpected obstruction, the survival ratio goes down to only 20% and 10%.

Objectives : The purpose of this study is to establish guideline for tooth whitening by investigating the awareness towards tooth whitening. Methods : The subjects were recruited in Seoul and Gyeonggi-do from June to August, 2011. A total of self-reported 395 questionnaire data were analyzed except for 5 incomplete answers. Results : 1. Smoking and coffee had no significant influence on the intention to whiten the tooth according to gender(p<0.001), age(p<0.001) and marital status(p<0.001). 2. Seventy persons (64.8%) tried to whiten tooth for color change. Half of the respondents (50.0%) bleached teeth by themselves. Of 295 persons, 66 persons (61.1%) were satisfied with self-whitening of teeth. Conclusions : Majority of the respondents wanted to whiten their teeth and they tried whiten by themselves because the whitening procedure was easy to do. It is necessary to establish the guideline for whitening teeth for safety.

In the current domestic, many industrial accidents have happened. And these are analyzed according to several factors. But it is difficult that they evaluate their business safety. Thus, we conducted a study on business specific safety assessment techniques in order that business know their safety level and perform appropriative safety activities. Study methods are survey and AHP (Analytic Hierarchy Process). Each specific weighting factors to calculate the survey was conducted for safety and consulting experts (20 persons). Weight factor was used to AHP decision support as one of the ways through a number of alternatives to the ratings for the Minesota Multiphasic. Factors are each type of industry, specific industrial scale, disaster type and strength, worker age and tenure period, and region. First, survey was conducted with 20 professionals to estimate the weighting factors. Weights between factors using the AHP analysis tool based on the mean values were calculated. Second, last 3 years between the industrial accidents statistics were used to calculate the weights for each of the rating factors in the Occupational Safety and Health Agency. Grade weights between each factor which was based on the rating of each factor was calculated as the average of three years. Finally, the weights between each factor and the grade weights for each factor using the safety level of the enterprise were calculated so that you can evaluate the weighting.

In this study, through a survey on traffic safety campaigns for electric wheelchairs for the disabled, we found out what is necessary to solve the inconvenience of disabled people driving electric wheelchairs and living in society. The conclusions for each role of the severely disabled are as follows. The government has enacted a law on fostering convenience facilities for the disabled in accordance with reality so that the disabled, who are vulnerable to transportation, do not have any inconvenience in their social lives. However, it is not kept in reality, so there are many obstacles to the social activities of the disabled. In addition, local governments should subscribe to electric wheelchair insurance for the disabled to minimize the damage to the disabled in the event of an electric wheelchair accident. Organizations related to the disabled provide safety wheelchair driving education to prevent electric wheelchair accidents in advance and receive complaints about inconvenience. It can be concluded that people with severe disabilities can prevent accidents in advance by installing a moving ring tone on an electric wheelchair so that they can know the movement of the surrounding wheelchair.

Predict-Plan-Do is the main point to settle Safety management well, but we have neither Predict nor Plan. So just like the system of English CDM is necessary to be adapted in construction work which makes them work in full responsibility by clarifying the responsibility located step by step from planning to designing & constructing-To adapt this system needs more money for Safety than now, but this system makes companies earn maximum confidence & profit by accident prevention. Furthermore leads the nation and the society to earn large profit, then open the road to Welfare State. If you sees only the things such as money, profit, etc before your eyes, no more safety remains. That means no more respect of persons and no more welfare state.
