The construction industry has the highest occupational fatality and injury rates related to accidents of any industry. Accordingly, safety managers closely monitor to prevent accidents in real-time by installing surveillance cameras at construction sites. However, due to human cognitive ability limitations, it is impossible to monitor many videos simultaneously, and the fatigue of the person monitoring surveillance cameras is also very high. Thus, to help safety managers monitor work and reduce the occupational accident rate, a study on object recognition in construction sites was conducted through surveillance cameras. In this study, we applied to the instance segmentation to identify the classification and location of objects and extract the size and shape of objects in construction sites. This research considers ways in which deep learning-based computer vision technology can be applied to safety management on a construction site.

Objectives : The purpose of this study was to investigate accident cases involving electronic assistive devices, to determine how these accidents can be avoided and to devise preventative instructions for the handicapped who use these devices. Methods : This study was carried out from July 20 to October 3, 2015. A consent-based survey was conducted via mail and mobile phones targeting 700 electronic assistive device users, of which questionnaires from 290 users were collected and used in the analysis. Results : Accidents involving electronic assistive devices were investigated, especially the causes of the accidents and accident prevention education, as well as the status of the electronic assistive devices. The most common accident types were collision and falling, and it was found that the victims of the accidents usually suffered severe injury to their lower limbs. Most users used electronic assistive devices every day but rarely wore a safety belt because of discomfort. There were more incidents of collision and falling for older aged handicapped users, and the injury rate to the lower limbs was highest in handicapped elderly aged 50 years or older. Conclusions : In order to prevent accidents with electronic assistive devices in the future, a or management organizations must prepare specific safety guidelines and manage these accidents.

Occupational fatal injury rate per 10,000 population of Korea is still higher among the OECD member countries. To prevent fatal injuries, the causes of accidents including human error should be analyzed and then appropriate countermeasures should be established. There was an severe converter furnace accident resulting in five people death by chocking in 2013. Although the accident type of the furnace accident was suffocation, many safety problems were included before reaching the death of suffocation. If the safety problems are reviewed throughly, the alternative measures based on the review would be very useful in preventing similar accidents. In this study, we investigated the converter furnace accident by using human error analysis and accident scenario analysis. As a result, it was found that the accident was caused by some human errors, inappropriate task sequence and lack of control in coordinating work by several subordinating companies. From the review of this case, the followings are suggested: First, systematic human error analysis should be included in the investigation of fatal injury accidents. Second, multi man-machine accident scenario analyis is useful in most of coordinating work. Third, the more provision of information on system state will lessen human errors. Fourth, the coordinating control in safety should be performed in the work conducting by several different companies.

This study examines the relationship between safety factors and health management systems based on accident statistics in the construction industry stipulated in the Serious Disaster Punishment Act. To determine the level of safety achieved by companies through their health management system, the top 1000 construction firms in the country were surveyed online. Four hundred sixty companies responded to the survey by providing their statistics on major accidents (mortality, accidental mortality, and injury rates). Statistical tests showed that companies with a team dedicated to the oversight of safety and health management had fewer accidents than those without one. Factor and regression analyses revealed that three factors affected the mortality and accident rates: safety and health plan, safety and health professionals, and safety and health activities. Moreover, two factors significantly influenced the injury rate: safety management supported by a cooperative company and implementation of on-site safety and health activities. The findings of this study can be used as a fundamental reference for further research and consultation on the formulation of safety and health management systems for construction companies.

Background: Motorcycles are one of the important members of commercial transportation because of the convenient use during congested traffic conditions and the ease of parking in narrow streets. This study investigates the characteristics of crashes and traffic signal violations caused by motorcycle couriers. Methods: From the national compensation data, this study analyzed the traffic crashes caused by 671 motorcycle couriers. Results: Among 671 injured couriers, 50.6% were aged less than 40 years, 49.2% run in a small business of <5 employees, and 47.2% had work experience of <6 months. Motorcycle crashes occurred mainly due to "rider overturned alone" (67.5%), in the daytime (73.5%), or on cloudy or clear days (77.2%). However, the violation rate caused by motorcycle couriers was high in couriers in a small business of <5 employees (13.9%), with work experience of <6 months (13.9%), on cloudy or clear days (12.4%), on an intersection (29.8%), in the type of "crash with a vehicle" (31.2%), or in a death accident (35.7%) Conclusion: The findings of this study can be used as a baseline in devising policies for preventing crashes of motorcycle couriers.

Purpose: Needlestick injuries (NSI) is the most frequent occupational hazard for healthcare personnel (HCP), and immediate report and adequate post-exposure prophylaxis (PEP) is essential in preventing occupational transmission of blood-borne pathogens. Methods: From June 2010 to October 2010, 544 NSI were reported through websites from 21 general hospitals in Korea. Among those, 499 cases of NSI were analyzed to identify the rate of follow-up treatment completion and for seroconversion. Results: 88.2% of the cases were completed with follow-up treatment, 8.8% of the NSI were not completed with follow-up treatment, and 5 cases were unavailable to trace. 4.2% cases of NSI required a hepatitis B vaccination concurrent with hepatitis B immunoglobulin. 41.1% of the cases and 31.1% of the cases needed to be tested for anti HCV and anti HIV, respectively. Prophylaxis medication for HIV was prescribed in 3 cases, and all cases completed required 1 month of medication. There was 1 case (0.2%) of seroconversion to HCV. Conclusion: The PEP completion rate was not satisfactory, and the importance of completion of PEP treatment should be emphasized through education and counseling. Also, a careful risk assessment is needed for HCP who are exposed to HCV or HIV.

Purpose: The aim of the present study was to investigate the effect of a PNF orofacial exercise program on diadochokinesis in subacute stroke patients with dysarthria. Methods: Thirteen subacute stroke inpatients with dysarthria were recruited for the study. All participants were randomly assigned to two groups: an experimental group (n=7) and a control group (n=6). The experimental group performed a PNF orofacial exercise program, and the control group carried out an orofacial self-exercise. Both groups received the treatments 30 minutes per day, 5 days per week, for 4 weeks. The outcome measures were assessed before and after the intervention, including an alternating motion rate (AMR) and sequential motion rate for diadochokinesis. Results: After the intervention, both groups showed significant improvement in diadochokinesis (p<0.05). In the change values for both groups, the experimental group showed a more significant improvement than the control group did in /pə/ of AMR (p<0.05). Conclusion: These findings suggest that PNF orofacial exercise programs may have positive effects on the improvement of diadochokinesis in subacute stroke patients with dysarthria.

In Korea, based on the Revised Law of Occupational Safety and Health a new entity of institution was set up in 1990 to provide occupational health services to SSE in which three sorts of personnel as a team have to be involved. These institutions, in charge of scores to hundreds of workplace area-wide, have been providing occupational health services without payment from employers or employees, and government reimburses through the Occupational Injury Prevention Insurance since 1993. As a service provider, a team is composed of doctors, nurses and industrial hygienists. Undergraduate and postgraduate educations for the SSE occupational health are not specified and the question on the performance of the personnel has been raised. This study was designed to analyze the facilitating factors of and barriers to the performance and its improvement of these personnel. In 1997, the survey was conducted with all 58 institutions. Structured questionnaires were mailed to 200 personnel who were providing the occupational health service for SSE. The response rate was 51.7% for doctors, 58.6% for nurses, and 60.3% for industrial hygienist, respectively. Results are as follows : 1) There is a guideline for occupational service mandated by the government. Under the guideline, the minimum frequency of visiting workplace is assured with six times of doctors, 17 times for nurse and industrial hygienist in a year. There are one doctor for every 200 factories, one nurse and one hygienist for every 100 factories. 2) All respondents have basic qualification for occupational health service. About 16.7%. of doctors are certified in industrial medicine or preventive medicine, and 64.7% of industrial hygienists had first grade certification. Totally 66.7% of personnel have been involved in occupational health for more than one year. 3) As a support system for the performance improvement, 66.3% respond that they have been provided with educational materials, advice related to industrial environment and guidance of MSDS from Korea Industrial Safety Corporation. Most respondents indicate the lack of concern of employers and employees as a main barrier to the improvement of the service. Also they are in the need of the training opportunity more focused on SSE. The Governments policy for SSE is a principal facilitating factor. Training program focused on SSE situation, manpower, technical support, etc. are areas to be improved to have a better occupational health service for SSE in Korea.

The history of occupational health in Korea s covered the era of the Republic of Korea after the Liberation from the Japanese colonialism. But the number of Korean workers exceeded about 2 millions at the times of liberation in 1945, so that it is expected that many occupational health problems inflicted Korean workers under the Japanese colonialism. The authors reviewed medical literatures, administrative documents, and other available data which were published under the colonial state, and collected things which had reference to the health status of Korean workers. The results were as follows : 1. Nutritional status of Korean workers was supposed to be inferior to that of general population, some students, and poor inhabitants in a remote mountain villages. 2. It was supposed that the constitution of Korean workers was near lower limit of average build of contemporary Koreans. 3. The accidents rate in mines was significantly high but decreasing year after year, and the most important cause of accidents was the fall of roof in the mine. The medical facilities and equipments for miners were supposed to be not sufficient in the mines and workshops. 4. Some occupational disease including silicosis, noise-induced hearing impairment, and decompression disease were known. But, overall incidence or prevalence of these diseases could not be identified. 5. On the whole, the fatalities of acute infectious diseases of Korean workers were higher than those of Japanese inhabitants in Korea and Korean inhabitants. The prevalence of pulmonary tuberculosis of Korean workers was increasing with every passing year. 6. The medical personnels and facilities were so deficient that most Korean workers were out of adequate medical use. We discussed only a part of the health status of Korean workers under the Japanese colonialism, so it would be necessary to have a better grasp of details of occupational health policy and health status in the era of afflicting.
