  • In this paper, a control method for field weakening region of induction machine drive which is based on indirect field oriented control was implemented. Also, application method of direct field oriented control in the field weakening region using maximum torque control methods which is adaptable for parking facilities was studied. The implemented method which is based on direct field oriented control method ensures the full utilization of the output torque capability of the machine over the conventional 1/${\omega}_r$ method. And machine drive system can obtain the robustness to motor parameter variation.

  • Studying the operation of urban control plan and control program of urban plan facilities to present development direction of urban plan in the future by performing multi-variate analysis, the research acquired the following conclusion. It is required to institutionally activate the inhabitants' participation by reflecting spontaneous participation and opinion of inhabitants to adminstration so that the effect of business can be maximized in the stage of establishing urban control plan. Furthermore, the participation of role dividing type is necessary to adjust and connect the interest of expert that has experience in practical business of overall urban plan, inhabitant and self-governing body. It is required to reduce the service supplied by government so as to enhance policy of plan-first and development last for facilities with high importance and utility such as road, park and water supply/sewage, etc as well as to seek control program that expands the participation of private sector for administration for which private service is possible.

  • In this study, we identify the suitability of monitoring the hygiene control of meals using ATP bioluminescence assay in children's foodservice facilities. Most ATP measured value by measurement area in childcare centers were lower in the second round than in the first round, and most hygiene control suitable rate by measurement area in childcare centers and kindergartens was higher in the second round. Also, in childcare centers, there was a positive correlation between the number of ATP measurement and the average score. In conclusion, ATP bioluminescence assay could be available as a monitoring tool for meal hygiene control in children's foodservice facilities, especially in childcare centers.

  • Usually, it is possible for human administrator to control the facilities manually or automatically using sensors in order to manage the fixed electricity facilities. However, it is difficult to collect the status data of those facilities in the central management system. In this paper, we propose the electricity facility management system to collect the status of facilities using the Zigbee networks. the proposed system exploits the various types of sensors, such as motion, heat, optical, etc, to measure the states of the facilities.

  • It is important to estimate the capability for the facilities and the condition of schools continually and correctly because the structure's life is remained more longer through the effective building control and preservation. In accordance with above of that, it is required to understand the knowledge about all matters at the stage of management for educational facilities and establish the procedure of the facility management consistently. This research suggests the method, which remains consistent and objective and deals with the total functional degree by following ㄴthe way to systemize the management plan of the facility estimation. The functional estimation of the existing facilities will be useful to make an plan for repair, maintain and checking of them as well as be the standard for remodeling and the educational facility duration, including long period project for building mending.

  • Recently, the rural village development projects are proceeding as enhancement of the rural landscape as the interest toward rural tourism and rural immigrant has increased. However, the projects are solely to support construction of community space and there has been a lack of community facility remodeling in term of both deterioration facilities and abandoned facilities. Thus in this study proposes rural community facility remodeling process to utilize remodeling of rural deterioration facilities and abandoned facilities. For setting rural community remodeling process, this study analysed preceding research data and suggested rural community remodeling process stage ; planning, spacial resolution, remodeling factor analysis, implementation, maintenance control, based on research data. For systematic performed this process, this study regulated role of local resident, expert and local government on remodeling process stage.

  • This study discusses application of the storm water management model (SWMM) to designing the sponge city facilities in the Athletes Village of Military World Games in Wuhan in October 2019. The SWMM was used to simulate the runoff processes and reduction efficiencies of the sponge city facilities. The runoffs of the sponge city facilities were compared with those of traditional drainage system for the design rainfall of 35.2mm and the rainfalls with different recurrence periods. The results show that the hign density sponge city facilities could meet the requirements for 80% of annual runoff control rate, SWMM can determine the scales of the sponge city facilities and effectively simulate the hydrological processes for different layout schemes. The simulation model is also helpful to making optimization of the sponge city facility layout.

  • The purpose of this study is to provide basic data needed for planning and designing apartment community facilities in order to vitalize rental apartments. Outdoors community facilities of six rental apartments in Seoul were examined. The results are as follows. Firstly, the conditions of planning characteristics showed that the convenience is ranked as the highest priority of planning, compared to safety, friendliness and finally comfortableness. Community facilities are connected with the apartments and sidewalk providing convenient access for all apartment residents, there was little regard given to the features of comfortableness. Secondly, comfortableness of community facilities were shown to the lowest, compared to any characteristics. It is not easy to control noise and privacy in facility, and there are lack of near community facilities, for washing hands, drinking water and shielding from snow or rain, respectively. Thirdly, green facilities were shown to the highest applied friendliness more than other facilities. They were well outfitted with water space and gardening spaces, and robustly applied environment friendly materials and colors. Fourthly, resting facilities were shown to the lowest applied safety more than other facilities. Structure and material of facility are favorable but there is an absence of nonskid material and night-lightening system.
