This study is to investigate the degree of field awareness of how each provision of the Serious Disaster Punishment Act will affect accident prevention. As a result of conducting a survey of construction site workers, it was analyzed that construction site workers had a low sense of safety and did not voluntarily engage in safety activities. And it can be seen that they are taking a very passive position that it is efficient to implement safety under the supervision of the supervisor. Workers who need voluntary construction site safety activities are most aware of the situation at the site, but the problem was pointed out as "lack of procedures for listening to opinions and preparing improvement measures" for these problems. Future research is needed to see if this is a problem for individual workers or for those in charge of safety and health who do not correct it even though active opinions have been submitted.

Hydrogen is difficult to accurately measure the amount of charge due to sudden temperature changes and pressure rise when charging the vehicle. In order to construct a hydrogen infrastructure, it is important to precisely measure the amount of charge that can be a sensitive issue in commercial transactions. In this study, the accuracy of metering of domestic hydrogen stations was evaluated as a study for metering management of hydrogen dispenser. For the experiment, we constructed metering system using master meter method and measured the flow rate in the actual hydrogen vehicle charging environment. As a result of error occurred about 10% on average, and the hydrogen loss per one charge was found to be up to 60g.

The port, differently from general working place, is a closed area to execute security, customs, and quarantine procedures. The loading and unloading is being done differently by cargoes, ships, berths, and equipments. To load and unload a lot of equipments and different types of labor are required, in which work flow is very complicated. As above mentioned the port is very unique and deteriorated working place including danger. The purpose of this thesis is to propose ways to analyze and establish the preventive measure for cargo handling accidents in port. We have collected 923 accidents happened at Incheon Port during the period from 1994 to 2003. And to analyze and establish the preventive measure we have employed an advanced 6sigma DMAIC technology presently in spotlight as the best tool for management innovation. For the purpose of effective safety management of cargo handling in port, this thesis will help to revise and establish the law, system, standard, and standard working manual with respect to the port loading and unloading system. Now frequency of cargo handling accidents in port is highest for the second time among all industries, so we proposed the new safety management system to substitute port safety committee and to take full charge of safety in Ministry of Maritime Affairs and Fisheries.

Electrodes were fabricated based on activated carbon powder BP-20, conducting agent such as Super P, vapor grown carbon fiber (VGCF) and acetylene black (AB), and the mixed binders of flexible poly(vinylidenefluoridehexafluoropropylene) [P(VdF-co-HFP)] and cross linking dispersion agent of polyvinylpyrrolidone (PVP) to increase mechanical strength. According to impedance measurement of the electrode with the addition of conducting agent, we found that it was possible to charge rapidly by the fast steady-state current convergence due to low equivalent series resistance (AC-ESR, fast charge transfer rate at interface between electrode and electrolyte and low RC time constant. The self-discharge of unit cell showed that diffusion process was controlled by the ion concentration difference of initial electrolyte due to the characteristics of Electric Double Layer Capacitor (EDLC) charged by ion adsorption in the beginning, but this by current leakage through the double-layer at the electrode/electrolyte interface had a minor effect and voltages of curves were remained constant regardless of electrode material. We found that the 2.3V/230F grade EDLC would be applied to industrial safety usage such as uninterrupted power supply (UPS) because of the constant DC-ESR by IR drop regardless of discharge current.

This study examined the current status of foodservice management in elderly welfare facilities and evaluated food service workers' food safety practices and knowledge. For this, the directors of 20 elderly welfare facilities (each with fewer than 50 residents) located in Seoul were interviewed and a survey of 40 foodservice workers was conducted to determine their food safety knowledge and practices. The facilities accommodated an average of 28 residents. All the facilities were self-operated and approximately 62% were dependent on payments by residents. Only 15% had a dietitian in charge of menu planning, food purchasing, and food safety management. Approximately 50% had their facility managers take responsibilities for menu planning and food safety management. Most of the facilities provided food safety training within their own facility and sanitized their utensils, cutting boards, and dishcloths on a daily basis. A limited number of foodservice workers, insufficient training programs, and budget constraints were some of the major barriers to food safety management. Their average score on food safety practices was 1.62, and that on food safety knowledge was 17.6 out of 19 points. These results indicate that the foodservice workers had good food safety knowledge and appropriate food safety practices. There was a significant correlation only between food safety practices related to receiving and storing food products and knowledge of personal hygiene.
