  • The construction inspection is conducted by the contractor or construction supervisor after a certain stage of work has been completed. As the consturction inspection task is dependant on construction schedule, however, it is difficult to plan inspection task systematically, resulting in increased supervision costs, delays in construction, and disputes. Therefore, this study aims to integrate inspection work with schedule management to systematize inspection procedures. Firstly, the inspection work is defined based on the construction supervision checklist. Then its relationship with the construction process, required time, and resources for inspection tasks are defined in construction schedule. Lastly, a process management program is used to assess the effects of applying the inspection work and examine changes in the overall construction period and process management. The proposed method in this study can support to plan construction inspection more systematically and to improve the effectiveness of construction quality management.

  • Objectives: The purpose of this study was to evaluate the characteristics of worker exposure to hazardous chemical substances and propose the direction of work environment management for protecting worker's health in the semiconductor assembly process. Methods: Four assembly lines at two semiconductor manufacturing companies were selected for this study. We investigated the types of chemicals that were used and generated during the assembly process, and evaluated the workers' exposure levels to hazardous chemicals such as benzene and formaldehyde and the current work environment management in the semiconductor assembly process. Results: Most of the chemicals used at the assembly process are complex mixtures with high molecular weight such as adhesives and epoxy molding compounds(EMCs). These complex mixtures are stable when they are used at room temperature. However workers can be exposed to volatile organic compounds(VOCs) such as benzene and formaldehyde when they are used at high temperature over $100^{\circ}C$. The concentration levels of benzene and formaldehyde in chip molding process were higher than other processes. The reason was that by-products were generated during the mold process due to thermal decomposition of EMC and machine cleaner at the process temperature($180^{\circ}C$). Conclusions: Most of the employees working at semiconductor assembly process are exposed directly or indirectly to various chemicals. Although the concentration levels are very lower than occupational exposure limits, workers can be exposed to carcinogens such as benzene and formaldehyde. Therefore, workers employed in the semiconductor assembly process should be informed of these exposure characteristics.

  • The article reviews the issue of formation of information culture of social work bachelors in the process of their professional training. The main internal / external factors that determine the need for the information culture formation of social workers-to-be have been identified. To determine the levels of information culture formed in bachelors of social work criteria and their indicators have been substantiated. The model of information culture formation in BSW has been developed and implemented in Ukrainian universities under the following pedagogic conditions: organized informational environment; interconnection between general and professionally-directed courses; curriculum includes course directed on IC formation. The model contained interconnected components: aim - to achieve higher level of information culture formed; specific principles; content, interactive methods and forms of organization of educational process, methods of control and correction; components of information culture. The implemented mastered learning procedure has contributed to the leveling up of information culture formed in social work bachelors.

  • This study aims to standardize the work classification system in spatial data. It is the base frame to classify the general information systematically in spatial data construction process. Work process of the surveying firm and rules for basic surveying which is being accomplished in the NGII(National Geographic Information Institute) are investigated and analysed. Therefore, types, individual process, and results of surveying work is standardized. If the work classification system from this study is adopted as the national standard and is also advanced by construction methodology, the spatial data will be managed futuristically and systematically.

  • There are insufficient models that find problems and solutions for accident prevention through risk assessment and suggest safe work process and work instruction from foundation works to finish work for accident decrease. This paper presents a quantitative risk assessment model by analysis of risk factors in each process such as earth works, drainage works, pavement works, appurtenant works and etc based on accident examples and investigation on actual condition in roads construction work. In addition, the safety management system was developed to perform risk assessment of construction and use it for effective safety training for labor.

  • The existing safety-management manual is confined to list data based on regulations, and only provide ways to prevent accidents/incidents for particular work which accidents occur frequently. As it is difficult to understand the complete process involved the work, we can not expect the manual to function as a guide to prevent unfortunate events. When establishing WBS(work breakdown structure) of railway line engineering, consideration of the characteristics of train operation will enable many benefits. Therefore in this research it is conducted to materialize it in the manual. Main contents in this research are to review the way that change complete work performance process and person in charge of different tasks into WBS(work breakdown structure), and trough the newly developed WBS , the ways to improve roles and functions of the manual which Korean Railroad made are recommended.

  • Since many resources are put into the work of changing the railway operation within limited time, it is important to have a specific work plan and safety management. For this reason, the work schedule is shared in advance, and parallel work is being carried out simultaneously by rail system, such as tracks, trolly wires, and signals. However, due to the nature of the transfer work, the work is carried out at night when the railway operation is finished, and many resources are put into the limited area of the operating line, so the risk of safety accidents and failure to change the operating line is recognized as high. Nevertheless, there is still not enough research done in korea regarding the operation line change construction. Therefore, this study is conducted a survey on the track exchange work of railroad for working people, and analyzed the results of the survey. Finally, a standard work process was suggested to reduce the risk of track exchange work.

  • Since construction materials have been towards larger and heavier, the rate of accident associated with installation works of heavy construction materials is increasing. Installation works of heavy construction materials lead to frequent accidents, increasing the WMSDs(Work-Related Musculo-Skeletal Disorders) in construction site. In case of installation work of heavy glass ceiling, the rate of accidents such as falling and collision is increasing as well. This paper describes a ergonomic design of working platform(deck) in a glass ceiling installation robot. As well as, a design of working process is considered to accomplish an efficient installation work. As a result of the design, an installation work of heavy glass ceiling by the robot will be expected safety assurance and retrenchment of the construction cost and period.
