Construction work is a labor-intensive industry, which is required systematic production activities using materials, manpower, and equipment. Among them, manpower resources play a very important role in achieving efficiently production in the organization. Construction work is highly dependent on construction craft workers, and the level of proficiency can be directly related to the construction productivity and quality. However, a rapidly aging construction craft workers in Korea, is being replaced by a foreign construction craft workers because of advoidance of new laborers in the construction site. In the future, if the continuous development and management of construction manpower is not made properly, it may be lead to adverse effects such as setbacks in production, delayed completion, faulty construction, industrial disasters, and decreased productivity in construction site. In this study, it was proposed four important factors for work capacity management of construction craft workers. These were ensuring of physical strength through the health management of construction craft workers, securing of proficiency through career management, ensuring of productivity through work capacity and establing of informatization through work capacity management. By introducing a systematic system, it is possible to improve construction craft workers' professionalism, enhancing the level of welfare, reflecting the realities of labor costs, increasing the quantitative and qualitative levels of construction craft workers, Futhermore it was demanded the continued interest and policy support for the realization of effective management of construction craft workers.

The construction craft workers have been getting older and have become drained, in spite of the vital factor that it directly affects productivity and quality as a final producer. This situation in the construction industry is ultimately due to evasion of performances by young craft workers. Therefore, the aim of this study is to propose the certification and level system of construction craft workers and to extract young craft workers from the market for construction craft workers so as to supply and demand high quality of craft workers. First of all, the present status and problems of the domestic construction craft workers are considered in this study. Furthermore, the appropriate way to establish its certification and level system is suggested from the Interview with experts, as well as references of German and Australian case. The revitalization of certification and level system provided in this study is expected to ensure that the craft workers are not simple laborers, but are required the professional knowledge and skill. Besides, it will lead to strengthen specificity and to break from aging, by taking young and qualified craft workers into the construction industry. Also, it will promote an employment stability by connecting the social security system.

Unlike other craft workers, construction craft workers perform their work under diverse working conditions, which means that their working pattern and postures continuously change. While construction craft workers are vulnerable to musculoskeletal disorders, due to the unique factors of their working conditions, their actual condition has not yet been accurately investigated. For this reason, this research aims to develop a method of measuring the musculoskeletal load of construction workers by reviewing various motion measuring methods to which state-of-the-art sensors are applied. This research is expected to serve as the basis for developing a system to measure the musculoskeletal load of construction workers.

The characteristics of construction work cause excessive strain on specific body parts of the construction craft workers. However, there are few tools to mane an accurate measurement of the load on the musculoskeletal system, and the musculoskeletal disorders (MSDs) experienced by the workers have not been properly understood. So, there is an urgent need for development of a tool to measure the load on the musculoskeletal system. Therefore, this research aims to develop a musculoskeletal load measuring device for construction workers. In order to eliminate the noise and errors, an accelerometer, gyro sensors and the Kalman Filter are used in the device developed in this research.

The construction industry has been experiencing a major challenge in its work force, 'the shortage of skilled craft workers.' This problem has been caused by several factors such as the poor image of the construction industry, lack of training and education, unclear career path, declining wages, and changing work force demographics. A 'step-change' approach called the 'Two-Tier Work Force Strategy' has been proposed by the Center for Construction Industry Studies (CCIS) to deal with the work force related issues in a radical way. It is composed of two separate strategies, Tier I and II. The Tier I strategy uses less skilled and task trained craft workers, and has a larger administrative site management team than the Tier II strategy. The Tier II strategy utilizes fewer, better-educated, and higher skilled workers who perform some lower-management functions in addition to craft functions. They are paid more, but produce more through higher skills, stay on the job longer through multi-skilling, and deliver improved project performance in safety, quality, schedule, and cost The Two-Tier Work Force Strategy has the potential to resolve the current work force problems and foster a better work force environment in the future.

The 7,993 cases of Survey Report of Fatal Industrial Accidents conducted jointly by the MEOL and the KOSHA for the recent seven years(2007-2013) were categorized according to personal and occupational characteristics, industry types, business sizes, job types, activities at the time accident, types of accidents, material agents(assailing materials), unsafe conditions, and unsafe acts. And it is found that among the 72.2 percent of fatal occupational accidents in the construction and manufacturing industries are caused by falling, sticking, bumping and being caught under objects & overturning. For this study, through the empirical analysis on causes of fatal industrial accidents, was used to identity high risk groups based on total data of 7,993 victims of occupational accidents. An annual fatal occupational injury (FOI) rate per 10,000 workers was about 0.47‱. The middle-aged group and the elderly group showed the highest FOI rates per 10,000 workers (0.73‱, 0.80‱), and the daily workers showed the highest FOI rate (1.46‱), and the craft and related trades workers showed the highest FOI rate (2.17‱). In case of industry type the mining industry (7.26‱) showed the highest FOI rate, followed by the sewerage, waste management, materials recovery and remediation activity industry (3.91‱) and the construction industry (2.71‱). The primary high risk target group that requires a strategy designed to reduce fatal occupation injuries caused by falling and bumping & contact(collision) is the construction industry, and the secondary high risk target group in the construction industry is classified as the equipment, machine operating and assembling workers in the construction industry, those aged 50 years old and above need the prevention measures against bumping & contact(collision) and being caught under an object & falling(objects), while those aged less than 50 years old need prevention measures against falling(persons).

Background: Due to an increasing number of workers aged 50 years and above, the number of those employed is also on the rise, and those workers aged 50 and over has exceeded 50% of the total fatal occupational injuries. Therefore, it is necessary to implement the selection and concentration by identifying the characteristics of high-risk groups necessary for an effective prevention against and reduction of fatal occupational injuries. Methods: This study analyzed the characteristics of high-risk groups and the occupational injury fatality rate per 10,000 workers among the workers aged 50 and over through a multi-dimensional analysis by sex, employment status of workers, industry and occupation by targeting 4,079 persons who died in fatal occupational injuries from January 2007 to December 12. Results: The share of the workers aged 50 years and above is increasing every year in the total fatal occupational injuries occurrence, and the high-risk groups include 'male workers' by sex, 'daily workers' by worker's status, 'craft and related-trades workers' by occupation, and 'mining' by industry. Conclusion: The most frequent causal objects of fatal occupational injuries of the workers aged 50 years and above are found out to be 'installment and dismantlement of temporary equipment and material on work platforms including scaffold' in the construction industry and 'mobile crane, conveyor belt and fork lifts' in the manufacturing industry.

The goal of this study was to investigate some significant factors to influence level of safety at plant construction field and analyze degree of risk by work classification. Currently, there are lots of construction fields for the nuclear power plant for electricity generation, and our government also planned constructing more nuclear power plant in near future. However, much of the safety literature neglected the degree of risk factors on the plant construction field. Safety managers participated in the brainstorming session for drawing decision criteria of the degree of risk (i.e., significant factors). Then, they were asked to answer a structured questionnaire which was developed for drawing most important factors. Finally, the analytic hierarchy process (AHP) was used to analyze level of risk by work classification. The following results were obtained. First, total twelve factors judging degree of risk were found in the brainstorming session. Second, the questionnaire showed four significant factors, including number of workers, working environments, skill of craft and accident experience. Third, the results of AHP showed Architecture work is the most dangerous work among 6 work types. The results could be used to reduce degree of risk in construction field of the nuclear power plant.
