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.

The flow and heat transfer characteristics of the ex-vessel core melt (corium) were investigated using a commercial CFD code along with the experimental data on the spreading of corium available in the literature (VULCANO VE-U7 test). In the numerical simulation of the unsteady two-phase flow, the volume-of-fluid model was applied for the spreading and interfacial surface formation of corium with the surrounding air. The effects of the key parameters were evaluated for the corium spreading, including the radiation, decay heat, temperature-dependent viscosity and initial temperature of corium. The results showed a reasonable trend of corium progression influenced by the changes in the radiation, decay heat, temperature-dependent viscosity and initial temperature of corium. The modeling of the viscosity appropriate for corium and the radiative heat transfer was critical, since the front progression and temperature profiles were strongly dependent on the models. Further development is required for the code to consider the formation of crust on the surfaces of corium and the interaction with the substrate.

Korea reached an aging society in 2000, and it is progressed quickly now. Government forecasts that the number of aged people over 65 years old will increase from 7.2%(2000) to above 14.3% among total population in 2018. Workers over fifty years old are increasing in construction field every year. These aged workers are exposed to various construction accidents, and also their accident rate is very high because of physical and psychological changes by aging. Specially, a disaster of aged workers more than 50 years old is fronted at the serious situation in the construction industry which has variable working environment. Thus, the purpose of this study is to suggest the precaution by analysing disaster characteristics of aged construction workers. Also, this study aims to present a basic counter-plan according to important safety management list which is abstracted from the work, aged construction workers' accident rate is high.

Purpose: The purpose of this study was to investigate the risk factors of intracranial hemorrhage in children with skull fractures from head trauma. Methods: The retrospective study included 205 patients diagnosed with a skull fracture in a pediatric emergency room. Data were analyzed using 𝓍²-test, Fisher's exact test, t-test, and logistic regression analysis with the SPSS/WIN24.0 program. Results: Intracranial hemorrhage was diagnosed in 71 patients. There were statistically significant differences between the hemorrhagic group and non-hemorrhagic group in age group, places of accident, type of accident, location of the fracture, and symptoms. Intracranial hemorrhage by age group was higher in school-age and adolescence than in infancy. The places of accidents of hemorrhage were higher in street and school than in the home. The types of an accident of bleeding were higher in the case of knock and traffic accident than in fall. Symptoms of nausea, headache, and loss of consciousness were associated with higher intracranial hemorrhage. Multivariable logistic regression analysis showed that knock (OR= 3.29, 95% CI= 1.50-7.22), traffic accident (OR= 4.78, 95% CI= 1.31-17.43), nausea (OR= 4.18, 95% CI= 1.42-12.31), and loss of consciousness (OR= 3.29, 95% CI= 1.41-9.50) were risk factors for intracranial hemorrhage. Conclusion: In this study, the risk factors of intracranial hemorrhage were identified in pediatric patients with skull fractures caused by head trauma. It is recommended that the results of this study be used to manage and educate patients, caregivers, and medical staff after head trauma hemorrhage.

In respect of incidence, there were the highest frequency in July, and the lowest frequency in May. The number of patients has not been increased year after year due to competition with other department in our hospital. 2. The age frequency was the highest in the 2nd decade(38.9%) and the ratio of man to women was 4.9 : 1. 3. The most frequent cause of mandibular fracture was traffic accident(43.4%), and the next was fall down(24.3%), fist blow(71%), industrial accident(21%) and others in order. In the traffic accident, autobicycle accident was 14.1%. 4. The most common location of mandibular fracture was symphysis(38.8%), condyle(20.7% ), angle(19.9%) and body(15.1%) were next in order of frequency. The classification by location of fracture, the frequency of single fracture was 54.8%. 5. In 334 patients of mandibular fracture, the frequency of associated injuries was facial laceration(58.4%), teeth injuries(37.7%), extremity injuries(13.2%) were next in order of frequency. 6. The patients arrived in hospital immediately within 24 hours after accident wee 61.4% of all. In respect of treatment, open reduction was 68.7% of all. 7.

This paper reports the aging driver traffic accident severity modeling results. For the modeling, Poisson regression approach is applied using the data set obtained from the Korea Transportation Safety Authority's simulator-based driver aptitude test results. The test items include the estimations of moving objects' speed and stopping distance, drivers' multi-task capability, and kinetic depth perception and so on. The resulting model with the response variable of equivalent property damage only(EPDO) indicated that EPDO is significantly influenced by moving objects' speed estimation and drivers' multi-task capabilities. More interestingly, a comparison with the younger driver model revealed that the degradation of such capabilities may result in severer crashes for older drivers as suggested by the higher estimated parameters for the older driver model.

The purpose of this study was to investigate the awareness of elementary school teachers on the socio-scientific issues. Fukushima Nuclear Power Plant Accident was used by concrete issue connected with SSI for this study. Participants in this study were twelve elementary school teachers studying at K University Graduate School of Education, located in the central region, who underwent a semi-structured interview. The study method was the phenomenological research method which is one of the qualitative research methods, and the interview papers had been examined by three scientific experts. As a result of the study, it was divided into twenty six themes, eight theme clusters, and two categories, and considered the thoughts on the Fukushima nuclear power plant accident, its influence on Korea, the relationship between science and society as a result of the Fukushima nuclear power plant accident, interested in social issues related to science, application in class, response from students and the influence on students. Teachers had a general understanding of science-related social issues, but did not have much interest in the subject. However, they mentioned that to apply the issues in the curriculum would have a positive influence and encourage scientific motivation in students and, furthermore, helped them to develop the awareness of science in their surroundings. A greater interest in socio-scientific issues need to require from teachers and, through including these issues in the curriculum, we should have positive influence in developing science education.

Efforts are being made to prevent traffic accidents within the child protection zone. Efforts are being made to prevent accidents by enacting safety facilities and laws to prevent traffic accidents in the school zone. However, traffic accidents in school zones continue to occur. If the driver can know the situation in the child protection zone in advance, accidents can be reduced. In this paper, we design a camera that eliminates blind spots in school zones and a number recognition camera system that can collect pre-traffic information. Design a LIDAR system that recognizes vehicle speed and pedestrians. Design an LED guidance system that delivers information to drivers without smart devices. We study time series analysis and artificial intelligence algorithms that collect and process pedestrian and vehicle information recognized by cameras and LIDAR. In the artificial intelligence traffic accident prevention system learned by deep learning, before entering the school zone, the school zone information is sent to the driver through the Force Push Service and the school zone information is delivered to the driver on the LED sign. try to reduce accidents.

Through this study, we developed a model for predicting chemical accidents lead to casualties. The model was derived from the logistic regression analysis model and applied to the variables affecting the accident. The accident data used in the model was analyzed by studying the statistics of past chemical accidents, and applying independent variables that were statistically significant through data analysis, such as the type of accident, cause, place of occurrence, status of casualties, and type of chemical accident that caused the casualties. A significance of p < 0.05 was applied. The model developed in this study is meaningful for the prevention of casualties caused by chemical accidents and the establishment of safety systems in the workplace. The analysis using the model found that the most influential factor in the occurrence of casualty in accidents was chemical explosions. Therefore, there is an urgent need to prepare countermeasures to prevent chemical accidents, specifically explosions, from occurring in the workplace.

Exactly 25 years after the Chernobyl nuclear disaster, 11th of March 2011 the Fukushima nuclear accident occurred in Japan and was ranked at level 7 same to the Chernobyl. A Korean and Japanese joint civil survey was conducted around Fukushima on April 13-17. The radiation survey data clearly shows a large hotspot area between 20 km and 50 km radius north and west direction from the accident reactors, with the highest radiation recorded being 55.64 ${\mu}Sv/hr$ in the air, 99.89 ${\mu}Sv/hr$ in the surface air, and 36.16 ${\mu}Sv/hr$ in a car, respectively. 3.65 ${\mu}Sv/hr$ in the air and 6.89 ${\mu}Sv/hr$ in the surface air were detected at the playground of an elementary school in Fukushima City. Spring came with full cherry blossoms in Fukushima, but it was silent spring of radiation contamination. Interviews with Fukushima nuclear refugees reveal serious problems about Japanese nuclear safety systems, such as there was no practical evacuation drill within 1-10 km and no plan at all for 10-30 km areas. Several reforms items for Korean nuclear safety system can be suggested: minimization of accident damage, clear separation of regulatory and safety bureaus with a new and independent administrating agency, community participation and agreement regarding the safety system and levels, which is the major concern of 80% Korean. To tackle threats of nuclear disaster in neighboring nations like China, a new position entitled 'Ambassador for nuclear safety diplomacy' is highly necessary. The nuclear safety of Korea should no longer be the monopoly of those nuclear engineers and limited technocrats criticized as a 'nuclear mafia'.
