Objectives: The utility of the system was analyzed by applying the smart safety technology system to the aging pipe rehabilitation facility construction classified as a confined space. Methods: Smart safety management system was applied to a site where the aging pipe rehabilitation work was in progress. The working environment was measured for 25 days, and the toxic gas saturation was analyzed according to the working time and working place. Results: Based on the measured results, two characteristic environmental changes in the confined space were confirmed. First, when working inside an aging pipe, the tendency of carbon dioxide saturation increases with working time and the number of workers. Second, oxygen decreases when working in a space away from the entrance. Conclusions: Various applications of smart safety technology have been confirmed based on the measured data, and this is expected to be useful for environmental characteristic analysis and safety management when applied to a confined space composed with various conditions in the future.

In shipyards hull forming is performed by the line heating method using a gas torch and by cold treatment using a roll-press. However, this forming process has some issues, such as difficulties in controlling and accurately estimating the amount of the heat input, as well as a harsh working environment due to exposure to loud noises and air pollution. The induction heating method, which is introduced in this paper, exhibits good control and allows for the estimation of precise heat input. Also, workers can carry out the induction heating in a comfortable working environment. In this research, the induction heating simulation, which consists of electro-magnetic, heat transfer and thermal elasto-plastic analysis, was developed and modified through induction heating experiments. Finally, the effective heating coil was designed for the automatic hull forming system based on the results of induction heating simulation. For the purposes of a future study, if an algorithm to obtain optimal working conditions is developed, automatic systems for hull forming can then be constructed.

The purpose of this study is to evaluate work values of hospital employees. Their work values was compared with that of other corporate's employees or among that of specialties in hospital. It was surveyed to 893 persons; 164 in hospital and 709 in others. The work values of hospital employees are similar to that of other corporate's employees. But they have first priority to working environment, and emphasize monetary incentive much more than hierarchical development. There are some gap in work value between age groups in hospital, different from other corporate. That means hospital manager need to development the more developed work value in hospital. The work values are different in monetary incentive, hierarchical development, safety, working environment, creativity among specialties in hospital. The more special employees emphasize much more to monetary incentive, hierarchical development, working environment and the less special employees have priority to safety work value. Specially, because the hospital managers want to have safety than creativity, it must to make some changing program of work value for advance of future hospital.

Due to various industrial accident that occur to the staff in the broadcasting production sites, the issue of safety at the broadcast production site is becoming a social issue. Nevertheless, not many researches have been carried out on the actual conditions of the staff's production environment and its safety issues. Therefore, the purpose of this study was to prepare a countermeasure based on engineering knowledge by analyzing working environment to improve the poor working environment of staff. First, this study analyzed statistical data of industrial accidents over the past five years to find out the current status of disasters at broadcasting production sites. As a result, the intensity of the accident was not weak in that the loss days was more than one month in 85% of accident. In addition, the type of accident was high in the fall/trip accidents. Second, this study visited 10 broadcasting production sites for risk assessment. By analyzing the characteristics of the working environment and 104 questionnaires, we predicted the types of accidents that can occur in the broadcasting production site. As a result, accident types such as fall, collision, and trip were relatively high, similar to the characteristics of construction site. Third, it was possible to quantify the scale of the risk in the broadcasting production, and as a result, the quantity of temporary structure and accident risk were proportional. In other words, this study analyzes broadcasting work environment and defines risk factors based on safety engineering knowledge. Finally, this study suggested a guideline to improve the safety of the broadcasting production site.

The purpose of this study is to research the actual condition of working environment, working clothes and personal protective equipments on workers at a construction site in winter. The one to one interview by questionnaire was performed with 33 males and 2 females workers of a construction site in Daegu at $1.3^{\circ}C$ air temperature, 28% R.H., 4.7m/sec air velocity. The questionnaire consisted of 21 questions including 4 personal characteristics questions, 12 working environment/performance questions and 5 working clothes/personal protective equipments questions. It was modified from the original questionnaire developed by Finnish Institute Occupational Health. We found that physical stress of workers increased and the ability of performance decreased. The workers felt the coldest at hands/fingers, feet/toes and the face part of cheek, nose and ears. They rarely wore thermal clothing for winter and answered that the thermal gloves for winter did not provided enough warmth. Even if the workers recognized the necessity of personal protective equipments for their safety, they did not wear them for efficiency of working performance. These results will be useful elementary materials for development of working clothes and personal protective equipments from the viewpoint of improving both working performance and comfort.

Recently, the scale of buildings has been increasing because of the high-rise trend and complexity of underground spaces. A significant number of steel structures have therefore been adopted for building construction. Since workers need to work in high places to install steel beams, many industrial accidents easily occur during steel-frame work. Furthermore, considering the increasing trend of building steel structures, the safety of the workers during the steel beam erection work is of concern. To improve the safety, a new type of joint, located between the steel column and beam, which can eliminate the need for working at the elevated height during steel beam erection has been developed in Korea. Using the newly developed technology in the construction field, the safety performance needs to be evaluated. This study presented the safety evaluation approach for the newly developed technology from the literature review, and applied the method to a self-supported steel joint. The result showed that applying the self-supported steel joint improved the safety of the steel erection work in terms of working posture, working environment, and risk exposure time.
