  • Many of the falling which is the number one risk factor in lethal accidents in construction could have been prevented if the right activity or supervising had been taken in time. All other measures do not preventive the fall, but rather intercept the fallen itself or preventive severe injury. The most common and the bets measures on the preventive measures are guardrails which are to be worn on the site. Workers always exposed the risk of serious accidents induced by causal effects related with environments around construction sites. In order to represent how to decrease the risk of workers, this study was accomplished with a number of interview with experienced site director, cheief of instructors, workers. And the questionaire survey (2012. 5~2012. 10) were used to make proposed policies which are expected to reduce critical disastrous accidents and strength authorized limits of director's management automatically.

  • The accidents which occurred between during february of 1997 to December of 2004 at the 2nd Daegu subway construction site have been classified. The accident types of injuries include accidental falls, falling objects which consist 53.4% of all accidents. This result is higher than the same types of accidents occurring at construction sites which are 46.3%. It was found that the 3.4 times more accidents are caused from safety measures and working methods than problems caused by lack of supervision. 78.0% of the accidents occurred at stations and at the ventilation area. 31.9% of the accidents occurred when the operation was near completion($81.0%{\sim}100.0%$) which means there was pressure to complete the operation to meet the set due date. In the case of 50.0% of the accidents were caused by workers with less than two month work experience. And lumbago is 6.9%, especially lumbago didn't showed before. Maybe accident should increase if not reduce a possibility of danger. In this study a literature search has been conducted for the cause of these accident types and respective suggestions are provided.

  • Purpose: The recent increase in electric scooter (e-scooter) use has been accompanied by an increase in injuries from e-scooter-related accidents. Studies have reported that most such injuries are minor, and physicians may therefore underestimate the severity of such injuries. This study investigated the types and severity of injuries caused by isolated e-scooter accidents (i.e., those that did not involve colliding with other cars or falling from heights). Methods: This prospective observational study was conducted from May to December 2021 at Dankook University Hospital tertiary medical center. The demographic data of patients injured in isolated e-scooter-related accidents were collected. All injuries were categorized by body part. Results: Fifty eligible patients visited our emergency department during the study period. Of these, 76% were categorized as nonemergency, and 62% were discharged after initial evaluation and treatment at the emergency department. Another 10% were admitted to the intensive care unit (ICU) and 18% to the ward, with nine patients receiving at least one operation. The average hospital stays were 2.4 days in the ICU and 9 days in the ward. One death occurred due to traumatic brain injury (overall mortality rate, 2%). Multiple fractures of the left third through ninth ribs combined with lung laceration and fractures of T12 and L4 were noted. Conclusions: Various types and severities of injuries can occur in isolated e-scooter accidents. While most such injuries are minor, some will require ICU admission or surgery, and deaths can occur. Physicians should not underestimate the severity of such injuries.

  • Even though the potential for an accident in nuclear power plants is very low, multiple emergency plans are necessary because the impact of such an accident to the public is enormous. One of these emergency plans involves a robotic system for investigating accidents under conditions of high radiation and contaminated air. To develop a robot suitable for operation in a nuclear power plant, we focused on eliminating the three major obstacles that challenge robots in such conditions: the disconnection of radio communication, falling on uneven floors, and loss of localization. To solve the radio problem, a Wi-Fi extender was used in radio shadow areas. To reinforce the walking, we developed two- and four-leg convertible walking, a floor adaptive foot, a roly-poly defensive falling design, and automatic standing recovery after falling methods were developed. To allow the robot to determine its location in the containment building, a bar code landmark reading method was chosen. When a severe accident occurs, this robot will be useful for accident condition monitoring. We also anticipate the robot can serve as a workman aid in a high radiation area during normal operations.

  • Due to the rapidly aging population, the death rate of elderly people by safety accidents has been increasing. In particular, precautions are needed for falls prevention because they either directly or indirectly cause death. In the case of elderly people, most of the fall accidents occur in dense residential areas, and particularly, the staircase poses a risk of falling. Therefore, a safety assessment should be performed from the design phase. However, in general, staircases are designed using existing stair data or only aims to satisfy the installation criteria. Laws and regulations only define minimum requirements for safety, so it is not possible to prevent fall accidents even if they satisfy the requirements. Therefore, this study proposes a simulation-based method for evaluating the safety of staircases. The behavioral characteristics of the elderly are implemented to an virtual user in a virtual space including staircases, and fall accidents are evaluated by the evaluation logic related to the behavioral characteristics. The result shows that the safety of staircases can be preevaluated and reflected on the design to reduce the possibility of fall accidents of the elderly.

  • Mobile scaffold is used as a work platform in construction sites. According to industrial accident data, 10 fatalities occur annually on average due to falling from mobile scaffold in construction sites. To prevent such fatal accidents, safety standards must be improved by analyzing the causes of fatal accidents related to mobile scaffold. Accordingly, we analyzed domestic and international safety standards for mobile scaffold and analyzed the fatalities (117 persons) caused by mobile scaffold accidents in domestic construction sites during 2011-2020 and found that fall, overturn, and collapse accounted for 88% (103 persons), 10.3% (12 persons), and 1.7% (2 persons) of fatalities, respectively. The main causes of fatal accidents were found to be non-installation or insufficient installation of safety rails and outriggers and incorrect sequence of work. Based on the analysis results, we proposed strategies for improving the safety standards, such as the use of advanced guard rails and wheel-attached outriggers, to enhance the safety and field applicability of the mobile scaffold. Technology development and improvements in the safety standards for the use of mobile scaffold will aid in the prevention of fatal accidents caused by mobile scaffold.

  • The purpose of this study was conducted with senior women of ages 65 in Community Center to identify effective exercise methods for preventing falling accidents by enhancing balancing skills through aerobic and foam roller exercise programs. There were 24 subjects : 11 aerobics group and 13 foam roller group. 30 minute exercise programs were conducted against both groups 12 times 6 weeks. Various tests, including Time up and go test, Forward reach test, One-leg standing with eyes open/closed and Y-Balance were conducted prior to commencing the exercise program. Wilcoxon's Signed-ranks test was executed to analyze the changes in balance of the aerobic and foam roller exercise group prior to and after the experiment, and Mann-Whitney test was executed to compare the difference between the two groups. The Y-Balance(post. medial) show statistically significant differences in the amount of change before and after exercise between the two groups, except for Timed up and go test, Forward reach test, Y-Balance(ant.), and Y-Balance(post. lateral), which did not showed statistically significant difference (p<0.05). Foam roller exercises are effective methods to enhance the balancing skills in senior women to prevent falling accidents.

  • In 2015, the number of senior citizens aged 65 and over in Korea was 6,662,400, accounting for 13.1% of the total population. Along with these social phenomena, risk information related to the elderly is increasing every year. In particular, a fall accident caused by a fall can cause serious injury to an elderly person, so special attention is required. Therefore, in this paper, we implemented a system that monitors fall accidents and informs them in real time to minimize damage caused by falls. To this end, beacon-based indoor location positioning was performed and biometric information based on an integrated module was collected using various sensors. In other words, a multi-functional sensor integration module was designed based on Arduino to collect and monitor user's temperature, heart rate, and motion data in real time. Finally, through the analysis and prediction of measurement signals from the integrated module, damage from fall accidents can be reduced and rapid emergency treatment is possible. Through this, it is possible to reduce the damage caused by a fall accident, and rapid emergency treatment will be possible. In addition, it is expected to lead a new paradigm of safety systems through expansion and application to socially vulnerable groups.

  • Many kinds of falling prevention systems with a safety block have been supplied in order to prevent falling accidents and acquire the long life and cost down for the maintenance. However, there are not the reliable and domestic the falling prevention system until now. Almost systems were imported from U.S.A, Japan, U.K and Germany. The structural safety of the imported safety block is satisfied sufficiently, but it has heavy weight due to the cover with the aluminum and thickness. Especially, the falling prevention system as the safety block is very expensive. It brings about flow the enormous money out of country. Furthermore it has a heavy weight when workers climbed the ladder with a falling prevention system and moved, many workers are not feeling themselves. Thus, the aim of this work is to develop a commercial self-escape SRL(Self Retracting Lifeline) with the safety block function that has a light weight and an advanced strength. The cost efficiency and convenience of the system and safety for workers also will be improved remarkably even though this system has a light weight. The results show that the maximum stress is obtained in each part by the lower more than yield strength and has sufficient safety in the developed new safety block.

  • The main purpose of this study was to survey baby-sitters who have experienced safety accidents of children ; the causes of safety accidents, wounded parts of the body caused by safety accidents and how to handle emergency situation. The research participants consisted of 31 baby-sitters who have experienced safety accidents of children and have been participating in Baby-Sitter Programs at S university, in Suwon Kyunggi Province. The data were collected from June 13th to July 4th, 2007 using open questionnaires on semi-structure. The data were analyzed using a SPSS PC+ statistical program. The results of this study were as follows ; First, according to the general demographics, it has indicated that 32.2% of baby-sitters who participated in this research are mostly the age group of between 41 and 50years old. And 48.3% of baby-sitters are graduated from high school. In addition, 83.9% of baby-sitters go married and 41.9% of them have only one child. Second, in terms of experiences about baby-sitting, 51.6% of baby-sitters mostly do their jobs in the afternoon. They usually cared 1 or 2years old babies in the afternoon time. 48.3% of baby-sitters experienced baby-sitting for less than 6months. And the financial support was the main reason why they decided to do baby-sitting jobs. Third, the causes of safety accidents while caring children, included 'falling down(22.6%)', 'baby-walker(19.4%)'. Also, it was found that 61.3% of children who had accidents were male. When safety accidents occurred, the baby-sitters had been doing 'feeding milk(29.1%)', 'going out(16.1%)' and 'self-care(16.1%)'. Also, it has shown that the accidents mostly occurred in the afternoon(64.5%). Fourth, the parts of the injuries in safety accidents, predominantly involved the parts of arms(38.7%), legs(25.8%) and head and neck(12.8%). In conclusion, this research was intended to provide the basic data in safety accidents of children who were cared by baby-sitters. In the further research, it is suggested that studying for safety accidents of children and safety education programs for baby-sitters should be necessary.
