The purpose of this study was to provide an operational model of the rehabilitation room for fire officers at disaster sites to improve the safety and resilience of fire officers. Therefore, we analyzed the operation related elements of the rehabilitation room-such as overseas rehabilitation room operation cases and previous studies- and managed different factors including, but not limited to, management and human resources, equipment and facility, and accessibility and convenience factors; afterward, the relative importance and importance of sub-layers in each field were measured. The priority of items for the operation of the rehabilitation room for fire officers at disaster sites was elucidated; after expert analysis, it was found that human resources were the most crucial factor. Finally, it was found that, in descending order, accessibility and convenience, administrative, equipment, and facility factors were also essential. Based on this, we proposed a rehabilitation room operation guideline for disaster sites.

There have been many research papers and practical implementations on the various EC(Electronic Commerce) aspects such as merchant system, security, payment gateway, legal and policy issues. However, it is very hard to find the systematic approaches and business process models from the viewpoint of the company willing to start B2C(Business-To-Customer) EC. Therefore, we develop business process models for the planning, systems analysis and design, implementation, and operation of internet shopping mall to suggest a guideline and reference model for the realization of successful B2C EC.

This work aims to develop a platform to investigate the effect of operation schedules on the building energy consumption and to derive a simulation model based optimal start and stop daily strategy. An open-source building energy simulation tool DOE2 is used for the engine, and the developed simulation model is validated using ASHRAE guideline 14. The effect of late-start/early-stop operation of HVAC system on the daily building energy consumption was analyzed using the developed simulation model. It was found that about 10% of energy consumption cut was possible using the control strategy for an hour of advance of the stop operation, and about 3% per an hour of delay of the start operation.

As a guideline for desulfurization and dehumidification pretreatment facility for optimizing utilization of biogas, the $H_2S$ concentration is set at 150 % which can be treated with iron salts, dehumidification is the optimum value for generator operation, and the relative humidity applied at the utilization of biogas in EU is set at 60 %. We have set up the generator facility guidelines to optimize utilization of biogas. The appropriate amount of biogas should be at least 90 % of the total gas generation, and the capacity of generator facility should be set at 20~30 %. In order to equalize the pressure of the incoming gas the generator, a gas equalization tank should be installed and the generator room average temperature should be kept at $45^{\circ}C$ or less. Since the gas is not produced at a certain methane concentration in the digester, the efficiency is lowered. Therefore, it is required to install an air fuel ratio control system according to the change in methane concentration. Therefore, it is necessary to compensate for the disadvantages of biogasification facilities of organic waste resources and optimize utilization of biogas and improve operation of facilities. This study was conducted to optimize biogas utilization of type of organic waste(containing sewage sludge and food waste, animal manure), investigate the facilities problem and propose design, operation guidelines such as pre-treatment facilities and generators.

The common life with modern urban residence, spending more than 80~90% of daily life in indoor environment, makes the importance of indoor air quality (IAQ) even higher. Many efforts have made to improve indoor air quality (IAQ), which requires those systematic approaches for field practice. A recent study reported that no general approach cannot be made for IAQ improvement due to the great deal of variety in different indoor environments. Those indoor spaces included in Korean IAQ regulation were classified based on their characteristics and the IAQ guideline was suggested for each group of indoor spaces. Apart from those indoor spaces, the classroom in elementary school has different characteristics. By introducing the systematic approaches, the elementary classroom was surveyed and analyzed to understand its characteristics in due IAQ consideration. Based on the characteristics, there are several IAQ control measures suggested, including ventilation operation, dust mat installation, and white board. $CO_2$ and airborne dust were monitored and analyzed in order to evaluate the effectiveness of each control measure to IAQ. It was found that the general level of $CO_2$ concentration was managed under the IAQ guideline by applying the ventilator operation. The ventilation was also effective to the fugitive airborne particulate in elementary classroom environment.
