Marine casualties and environmental pollution have increased recently. Especially, the rate of incident of Coastal tankers is higher, but the assessment tool for safety management system is lack in this fields. However Oil Major Vetting System being professional assessment tool for tanker is widely applied in ocean going tanker by the worldwide Oil Majors. According to the analysis of the marine tankers' incidents which applied Oil Major Vetting System, the incidents were reduced rapidly for recent about 5 years. Using Oil Major Vetting System is helped to improve safety management and to prevent marine incidents. Therefore if applying a parts of the Oil Major Vetting Systems to the coastal tankers' Safety Management System, the Coastal tankers incidents would be reduced and improved gradually.

Introduction: Despite huge investments in new technology and transportation infrastructure, terrible accidents still remain a reality of traffic. Methods: Severe traffic accidents were analyzed from four prevailing modes of today's transportations: sea, air, railway, and road. Main root causes of all four accidents were defined with implementation of the approach, based on Flanagan's critical incident technique. In accordance with Molan's Availability Humanization model (AH model), possible preventive or humanization interventions were defined with the focus on technology, environment, organization, and human factors. Results: According to our analyses, there are significant similarities between accidents. Root causes of accidents, human behavioral patterns, and possible humanization measures were presented with rooted graphs. It is possible to create a generalized model graph, which is similar to rooted graphs, for identification of possible humanization measures, intended to prevent similar accidents in the future. Majority of proposed humanization interventions are focused on organization. Organizational interventions are effective in assurance of adequate and safe behavior. Conclusions: Formalization of root cause analysis with rooted graphs in a model offers possibility for implementation of presented methods in analysis of particular events. Implementation of proposed humanization measures in a particular analyzed situation is the basis for creation of safety culture.

Grenfell Tower was renovated in 2014 and 2016 at a high cost to replace the exterior materials, windows and co-heating facilities of the building. The exterior materials used during the repair work were sandwich panels filled with polyethylene and plastic, which were expanded on the aluminum metal surface. It is a product called Celotex RS 5000, a low-resolution but inexpensive repair material, and is currently an external material that cannot be used in high-rise buildings. Similar domestic fire cases began to focus social attention on the safety of high-rise buildings through the Busan Residential Complex Fire (2010), Uijeongbu Urban Living Housing Fire (2015), and Ulsan Residential Complex Fire (2020), and residents' safety concerns are increasing. In Korea, the occurrence and risk of similar fires are high, so setting up fire prevention measures through fire case investigation is considered the most basic measure in securing human safety. Therefore, the purpose of this study is to examine the status of fire damage caused by domestic and foreign eruptions, domestic and international research status and related regulations on external materials and windows starting from the Grenfell Tower fire in England.

This paper has two objectives. One is to introduce a software package, "FASTLite" for fire safety engineering calculation, the other to show the modeling result of a backdraft incident on the 62 WATTS street. A classic backdraft usually persists only seconds before exhausting their fuel supply but in this case the flame had persists for at least 6 and a half minutes. It is truly necessary to find out where the fuel came from to feed this flame for so long. The backdraft is successfully modelled by using FASTLite. To help understanding of this backdraft, the calculation with the door open is also carried out and compared to the backdraft.

To prevent incident of demolition work the Building Management Act was implemented to manage demolition work. According to this law, buildings with the scale upper than 500㎡ of floor area are classified as permission to conduct the demolition work, however it may be hard to perform safety management at demolition work. In addition, the risk level of demolition work is varied with related to the structure type. So, the purpose of this study is to suggest the improvements of criteria on demolition work considering building structure types including small-scale structures such as masonry, wooden, and other structure. The research process was conducted by three steps. (I) Application of Building Management Act; (II) Analysis of demolition work by structure types; and (III) Subdivision of permission targets by building structure types. The result of this study, permission ratio was only 10% for total demolition work and 2.43% for masonry. Because the masonry, wooden, and other structure types are concentrated on a floor area of small-scale, the separate criteria of demolition work is need to prevent the accident and fatal incident. Through the results, the decision maker can be utilized (1) For the special building structure types, the criteria of enhanced safety management are applied by referring to the overseas law ; and (2) The demolition work can be considered by the criteria of separate permission in terms of structure types.

An emergency manual is designed to minimize the extent and effect of lives and assets; it is not designed to prevent an accident. There have been continuous arguments in terms of manual effectiveness regardless of the fact that much effort and great cost have been invested in emergency planning and operations. The problems are that there are a number of different emergency manuals, that these manuals are hard to understand and rarely used due to their complexity, that they provide little direction toward the taking of action, and that coordination is difficult between those involved; all of these problems are related to two different pieces of legislations that define emergency manuals in different ways in terms of the contents required. The study has tried to respond to these arguments by exploring relevant legislation to identify emergency manuals that can be used to respond to rail incidents/accidents, for which previous responses have seemed inefficient. Further, some parts of the emergency manual contents are found to overlap, including the ways of differentiating incident responses, personnel roles and responsibilities by types of accident, and threat levels, all of which has resulted in unnecessary pages of the manuals. In preparing and operating such manuals, this study recommends that one piece of legislation that directly affects rail undertakings must be applied in an effort to increase effectiveness.

Purpose: The aim of this study was to compare job satisfaction, quality of life (QOL), incident report rate and overtime hours for 12-hour shifts and for 8-hour shifts in a pediatric intensive care unit (PICU). Methods: A descriptive survey was conducted with a convenience sample of 36 staff nurses from a PICU in a regional hospital in Korea. Data were collected using self-administrated questionnaires regarding job satisfaction and QOL at 6 months before and after the beginning of 12-hour shifts. Incident report rate and overtime hours for both 12-hour and 8-hour shifts were compared. Comparisons were made using $x^2$-test, paired t-test and Mann-Whitney U test. Results: After 12-hour shifts were initiated, job satisfaction significantly increased (t=3.93, p<.001) and QOL was higher for nurses on 12-hour shifts compared to 8-hour (t=7.83, p<.001). There was no statistically significant change in incident report rate ($x^2=0.15$, p=.720). The overtimes decreased from $36.3{\pm}34.7$ to $17.3{\pm}34.9$ minutes (Z=-8.91, p<.001). Conclusion: These results provide evidence that 12-hour shifts can be an effective ways of scheduling for staff nurses to increase job satisfaction and quality of life without increasing patient safety incidents or prolonged overtime work hours.
