In recent studies, construction industry workers with higher job stress and lower work ability were more likely to experience accidents at their workplace. Likewise, fatal accidents rate was higher among simple labor workers compared to technical workers. Therefore the evaluation of a worker's job stress and work ability seems to be important in preventing the occurrence of fatal accidents. To search for ways to reduce job stress and to improve work ability, the current study conducted a job stress analysis based on age, years of service, skill level, hobbies, sleep patterns, and monthly income. For this, the Korean occupational stress questionnaire short form and the Work Ability Index (WAI) developed by the Finnish Institute of Occupational Health (FIOH) were used. In this study, SPSS 12.0K statistics program was used for statistical analysis and significance was verified by the Kruskal-Wallis test and non-parametric tests. The results of this study can be summarized as follows : (1) Simple labor workers had higher job stress and less work ability than technical workers. (2) The more experienced workers had lower job stress and higher work ability. (3) In the case of workers who slept a lot, work ability was higher and job stress was less. (4) Monthly income influenced on the job stress and work ability. (5) Job stress and work ability in accordance with the age difference was not significant.

As the workers are getting old, they need to be expert in their fields. Expertise is an invaluable means of shipbuilding industries because of the technological advancements. Therefore, the workers have to attend training seminars and upgrade their technical knowledge. In shipbuilding industries, most workers operate transporters based on experience not on learning from specialization in the shipyard. It is needed for the workers of transporters to be educated technical manual and system. Thus, this research shows that educational system which is interactive and very effective with Augmented Reality(AR) for the non-specialist workers. The educational interactive system based on AR is very supportive and worth for the workers. This study considers the system which makes the workers reduce malfunction of the products and mistakes.

Poor working conditions in the construction industry have made young people reluctant to enter it, resulting in supply/demand unbalance of construction skilled worker. Currently, most construction workers in Korea acquire skills through apprenticeships. Against this background, this study aimed to identify problems in apprenticeship-based methods of technical education, and to suggest measures that could improve these methods. As a measure to improve current apprenticeship-based methods of technical education, technical education needs to be regularly provided on construction sites, and each construction company needs to issue a certificate to workers confirming their completion of technical education. It is also necessary to establish a system in which this certificate is recognized as education experience. In addition, it is recommended to form partnerships with construction technology education institutes supported by the government in order to provide construction workers with opportunities to receive new technologies and construction methods free of charge, and it is urgently necessary to establish and implement a policy to adequately support their cost of living during this period.

Objective: The aim of this study is to analyze the reliability assessment of work environment measurement, and to propose ways of improving the system. Methods: We have reviewed reports and articles on the reliability assessment written by KOSHA and academia in order to analyze problems related with the system and propose the alternatives. Results: There are three ways to improve the system of the reliability assessment. First of all, it is necessary to perform the reliability assessment by measuring the work environment when workers raise questions about the results so we can make workers trust these results of the reliability assessment. Secondly, we should inspect the workplace at first, not the work environment service provider, so we can increase the employer's recognition of his duty to practice the work environment measurement. Thirdly, the technical committee is needed for technical issues related with the work environment measurement. Conclusions: Above all, it is crucial to get the workers' interest and trust to improve the work environment measurement. The reliability assessment should support the meaning and value of the work environment measurement by practicing the reliability assessment whenever workers have a demand for this and operating the technical committee.

The distribution live-line work method is an operation method of working in a state in which electricity flows through overhead distribution lines to minimize inconvenience to electric customers due to power failure. In June 2016, to strengthen the safety of electrical workers, Korea Electric Power Corporation announced that it would in principle abolish the rubber glove method, in which workers wore protective equipment such as rubber gloves and performed their maintenance work. In addition, KEPCO announced that it would develop a short-range live working method using smart sticks and an advanced live-line maintenance robot system where workers work without touching wires directly. This paper is a preliminary study for the development of the live-line maintenance robot system, and deals with the results of analyzing the technical feasibility of whether the live works performed by workers can be replaced by robots or not.

Objective : Solitaire AB stent-assisted coiling facilitates the endovascular treatment of wide-necked intracranial aneurysms. We present our experience of coiling the micro-aneurysms of wide-neck with Solitaire AB stent assisting in a single center. Methods : Thirty-one Solitaire AB stents were used to treat via endovascular approach patients with 31 wide-neck micro aneurysms in a single center in China. Technical and clinical complications were recorded. Modified Rankin Scale was used to evaluate the patients' conditions via clinic and telephone follow-up. Results : The mean width of aneurysm sac was $2.30{\pm}0.42mm$, and the mean diameter of aneurysm neck was $2.83{\pm}.48mm$. Complete occlusion was achieved in 28 aneurysms (90.32%); neck remnant was seen in 3 aneurysms (9.68%). Technical and clinical complications related to the procedure were encountered in four patients (12.5%). Two patients died (6.25%). No patient had a permanent deficit. Conclusion : Solitaire AB stent was a safe and efficiency tool in assisting coiling of micro aneurysms with wide neck, but may be not suitable for a blaster-like one. Mid- and long-term follow-up will be required to elucidate the impact of the Solitaire AB stent on recanalization rate.

Background: During 2011, a study was undertaken to assess safety conditions in Serbian underground coalmines by analysis of injury data. The study covered all Serbian coalmines, identified week spots from the aspect of safety, and recommended possible courses of action. Since then, Serbia has made changes to safety and health legislation; all coalmines introduced new preventive measures, adopted international standards, and made procedures for risk management. After 10 years a new study has been performed to analyze the impact of these changes. Materials and methods: In this study, the injuries that have occurred in the Serbian underground coal mines over the last 20 years were analyzed. Statistical data analysis was performed by IBM SPSS Statistics v23. The injuries that occurred in the last ten years were compared with the results of the previous study (2000-2009). The average values of injury rates for both periods were compared for each of the categories (severity, age, body part, qualification), and the results were presented as absolute difference or percentile difference. Results: The results showed reduction in the number of injuries in the category of 20-30 years old workers, where the new training procedures for workers, which were set by mandatory legal regulations, certainly contributed. They also showed an increase in the number of injuries in the category of old workers, which indicates that the law did not have a positive effect on this category. Conclusion: The total number of injuries is still high; therefore, it is necessary to introduce mechanization and automation in mines and have a better policy for older workers who retire later nowadays.

Metro subway construction is a field that requires a great deal of professional manpower. The aging of professionals has a negative impact on both productivity and health, owing to poor working environments, heavy lifting, underground work, and other factors. To address this issue, the government is progressively revising and enforcing health management law and regulation in the construction industry. Thus, the job stress and work ability of many professional subway construction workers, who are rapidly aging, are being analyzed to ensure their safety and improve their health. In this study, the Macpa stress index of Busan Metro Subway construction workers from Sasang to Hadan line was measured by using a Macpa measurement machine, and a work ability survey was conducted by using the questionnaire that was developed by the FIOH. The independent variables were age, years of service, job position, employment type, and occupation. While, the dependent variables were the Macpa stress index and work ability. The Kruskal-Wallis test was used because it was difficult to assume that the statistics of this study represented a normal distribution. The results showed that age, job position, and employment type affected Macpa stress index and revealed that as the age of the workers increased, their stress levels increased as well. Additionally, job position and employment type affected the work ability of the metro subway construction workers. In terms of job position, the technical engineers were under a lot of stress, and whereas the managers had the best work ability. The technical engineers were more stressed than the other workers because of a poor working environment. In terms of employment type, daily workers were under more stress and lower work ability than others.

The children of sex workers in Bangladesh are denied even the most basic human rights. This article is based on recent research focused on the children of sex workers in the context of their everyday lives. The study focused on access to education and how education could be a vehicle for them to break the vicious cycle of exploitation. This was a mixed method interpretative study which employed qualitative and quantitative approaches, but in this paper only qualitative data which was generated through in-depth interviews and focus group discussions is used. Data was collected from sex workers, their children, teachers and NGO workers who participated in the study. Information has been collected for analysing the expectation of the children of sex workers and hope for the future, and the opportunities available to them during their schooling. Thematic analysis technique was used to understand the challenges and barriers faced by the children of sex workers in fulfilling their educational aspirations. The lives of the children of sex workers are marginalised by the mainstream society. Though it is very difficult to break the vicious cycle of exploitation, this research finds that education may be a stepping stone for them to create a better future. However, it is argued that the children of sex workers need income generating vocational and technical education to enable them to earn and support their family. Policy recommendations have been made in order to achieve Education For All targets and Millennium Development Goals, and to provide a second chance for these vulnerable young people to have a better life.
