  • The automotive headrest is intended to provide comfort, safety, convenience and durability to a vehicle's passengers and driver. In this study, impact and fatigue analyses were carried out for three headrest shape models-A, B and C. These models have the same material properties and the same force was applied to them. Impact and fatigue analyses demonstrated that all of the models obtained almost the exact same result values. This study found that all models had similar equivalent stress, deformation, fatigue life and main damage parts due to the fact that the shared same material properties. Better safety and fatigue life can be anticipated by changing the material of the headrest in order to secure more stable safety. An automotive headrest optimized for safety and durability is thought to have been developed through the impact and fatigue analyses of this study.

  • Due to the frequent occurrence of large-scale disasters such as recent earthquakes, the problem of the safety of old school buildings has emerged. The need to secure safety management technology through constant monitoring is increasing in an attempt to supplement old school buildings with weak disaster response capabilities. Traditional research is approaching the development of an existing sensor-based risk precursor information monitoring system. However, unlike this, in this study, we will focus on the development of a data analysis platform as part of the development of a continuous monitoring system that can be prepared for earthquakes, collapses, and fires, based on constantly measured data. For this reason, the development of a safety diagnostic algorithm based on the optimal sensor-attached points and sensor data reflecting the fragile characteristics of old school buildings was derived. Utilizing this, a message and action manual system for each management / use entity of school buildings after retirement was constructed.

  • Recently in the construction business construction companies has been ordered to survive in the terriblly competitive environment. Aa a result, most of the project with low-priced contract needs a speedy progress during all construction period. For the last five years major incident frequently occurs and results in the death of 189 workers at major top 6 construction builders. In most recent 10 years, the cause of major incidents happened in construction company is the speedy construction work that is affecting on the safety management. To prevent these accidents in the speedy construction work, four factors were chosed and analysed such as the personnel/organization, the working budget, the subcontractor selection and the employee motivation. The head office taked the support plan and tested it at the pilot work site. It showed a reduced accident and the harmful factors can be eliminated. It should be able to apply to the field to secure safety and prevent accidents.

  • When the foundation work of the underground part of the building structure or the excavation work of the civil engineering structure is carried out, there is the earthwork work by the inevitable process. As the economic situation continues to develop, construction in urban areas is becoming bigger and higher in scale due to the expansion of infrastructure and the rescue of urban dwellings in urban areas, and excavation of underground roads is inevitable. Excavation of the underground part may cause problems in the process difficulty and safety of the earthworks due to the complexity and various characteristics of the ground selected without consideration of the ground characteristics and site conditions. In order to complete the required facilities, it is necessary to secure the design and construction of the retaining walls. In order to complete the required construction, It is an important factor satisfying construction period and economical efficiency.

  • Recently, carelessness on safety management in construction sites has caused a sharper upward trend in accidents and disasters, compared to the past. Therefore, this study analyzes the causes of accidents that occurred on construction sites in the year of 2007, and proposes preventive measures. The construction industry had a heavy death rate with 279 out of 418 deaths from falls in all industrial sites, accounting for 66.7%. And the causation analysis found a particularly high incidence of temporary structure-related accidents, with falling off scaffolding as the most common cause of accidents. According to the causation analysis of fall-down accident cases, accidents induced by protrusion on construction sites are a big contributor resulting in the deaths of 312, accounting for 74.8%, which is deemed to be due to site disorderliness. And to remove floor protrusions and to secure workers' traffic line and safety, neat and thorough site arrangement is necessary. Against collision, efforts must be made to prevent equipment-pedestrian crashes on site, which necessarily requires emergency lamps, alarm bells, and safety poles and blocks to be installed, lighting systems to be improved, obstacles to be removed, site supervisors to be assigned to construction equipment works, and workers to be more intensely trained and supervised.

  • The crash cushion has drawn a great attention because of its versatility, efficiency and simplicity in reducing the mortality and damages from traffic accidents. However, the existing cushion systems are high priced or have limited functions. The purpose of the study was to devise an improved crash cushion which can offer higher safety compared to the available ones at present. In addition, the conformity of the cushion with the facility standards was assessed through computer simulation for collision with vehicles. The novel cushion system adopts the used tires as shock absorber, which can not only secure cushioning effect but also reduce the production cost. Moreover, it is highly durable and easy to maintain and repair the damaged parts. According to the simulation using BARRIER VII program, the novel cushion system showed PHD of 17.4 g and 10.1 g for a frontal collision and a side collision, respectively. Based on the results, it could be concluded that the novel cushion system met the test standards in the guideline for road safety facility installation and management.

  • Through the survey on the current status of hazardous substances in laboratories, the research institute is designed to establish measures to improve the management of university laboratories and to create a safe laboratory. We intend to explore countermeasures by confirming and reviewing the recognition of the statutes in the "Guidelines for the Implementation of the Laboratory Pre-Hazard Factors Analysis" through the questionnaire. Although there are various parts to create a pleasant environment for a laboratory, the most important part is the role of a laboratory manager in the area where each and every one of the laboratory's directors is the "Act on the Establishment of a Safety Environment in a Laboratory", but if the laboratory is not to be accident-prone, the laboratory's responsibility is to be more secure. This research is intended to be funded by research to reasonably implement" Guidelines for the Implementation of the Laboratory Pre-Hazard Factors Analysis" before applying to universities and to protect field-based research activities and to reasonably reduce safety accident prevention and risk.

  • This paper analyzes quality management of aviation safety services in Korea and proposes practical implications for improvement. We look into how quality management is conducted in the Korean aviation industry and confirm aviation authority's efforts for a quality management system. We also compare and analyze international standard ISO 9001 and aviation safety oversight system quality management cases of International Civil Aviation Organization (ICAO) and U.S. Federal Aviation Administration (FAA) with a Korean case. Results find the difference in defining the scope of ISO 9001 management between ICAO/FAA and the Korean authority which causes unnecessary misunderstanding in oversight perception. The Korean aviation authority strives to provide a high level of safety oversight services by educating aviation safety inspectors as well as establishing a quality management system. We believe that our proposals can help Korean aviation safety oversight system secure objective credibility and seek a safe growth and development of the aviation industry.
