Various disasters have been continuously occurred in Korea from 1990s to now. However, there is no substantial improvement against damages as compared with the past due to various reasons such as lack of fundamental recognition, ineffective response systems and widespread insensitivity to safety. More worse, new types of disasters have been frequently generated due to rapid changes in social structures and industrial development, unusual changes in weather and changes of international situations. These disasters request comprehensive countermeasures. In particular, while material damages by disasters can be recovered, the losses of precious lives cannot be recuperated in any ways. Thus, it is critical to set effective disaster medical plans. The first way to minimize damages by disasters is the prevention and the next is to set the disaster medical plans focusing on preliminarily activating the emergency medical system to rapidly rescue and take appropriate emergency medical services for casualties in the early stage when any disaster occurs. Nevertheless, no sufficient researches or references do not exist up to now. Even worse, effective emergency medical systems that play critical roles in increasing survival rates of casualties in actual disaster areas is not deployed. For the United States, the consistent countermeasure system is established in FEMA through a close cooperative system with relevant organizations for serious accidents including terrorists' attacks or natural disasters. For the emergency medical services in disasters, the disaster medical plan is set to cope with any disasters in perfect order by special area as operating the National Disaster Medical SystemESF#8 Role by FEMA. Accordingly, we need to set the extensive and integrated disaster prevention system for rapid and flexible operation against various kinds of serious accidents. This study identified overall problems in disaster control plans in Korea and suggested how to improve the emergency medical service system in disaster areas. Furthermore, it aims to prepare the basic data to set the effective emergency medical service plans when substantial casualties break out and more reasonable and systematic disaster control plans to cope with the future occurrence of serious disasters.

This study aimed to compare the performance of previous optimization algorithms against new a photon optimizer (PO) algorithm for intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) plans for prostate cancer. Eighteen patients with prostate cancer were retrospectively selected and planned to receive 78 Gy in 39 fractions of the planning target volume (PTV). All plans for each patient optimized with the dose volume optimizer (DVO) and progressive resolution optimizer (PRO) algorithms for IMRT and VMAT were compared against plans optimized with the PO within Eclipse version 13.7. No interactive action was performed during optimization. Dosimetric and radiobiological indices for the PTV and organs at risk were analyzed. The monitor units (MU) per plan were recorded. Based on the plan quality for the target coverage, prostate IMRT and VMAT plans using the PO showed an improvement over DVO and PRO. In addition, the PO generally showed improvement in the tumor control probability for the PTV and normal tissue control probability for the rectum. From a technical perspective, the PO generated IMRT treatment plans with fewer MUs than DVO, whereas it produced slightly more MUs in the VMAT plan, compared with PRO. The PO showed over potentiality of DVO and PRO whenever available, although it led to more MUs in VMAT than PRO. Therefore, the PO has become the preferred choice for planning prostate IMRT and VMAT at our institution.

The purposes of this study are to comprehend the importance of policy in improving the operation of the public arboretum and survey the program satisfaction of participants and operators based on the case of the Daegu arboretum. According to the order of policy priority regarding the Daegu arboretum, the expansion of the education program topped the list with 0.155 points, followed by the establishment of a vision and goal, and the reestablishment of function, which scored 0.135 and 0.135 points, respectively. Fostering citizens' participation through volunteer work was in the upper ranks with 0.131 points. Building networks among public arboretums and constructing a research cooperation system with universities turned up with 0.09 and 0.075 points. As the result of program satisfaction, participants' satisfaction was around 0.66 points higher than that of operators' satisfaction. In the case of participants, comprehensive satisfaction, including that with the program operation method, was very high at 4.85 points. Out of the entire program, the operators were the most satisfied with the benefits. This study aims to share improvement plans for public arboretums constructed in urban areas, analyzing policy priorities and satisfaction related to the Daegu arboretum. The results of this study can be utilized as data for the improvement plans of public arboretums. If improvement plans for public arboretums are modeled with other follow-up case studies, it will help ensure that public arboretums become evolving rather than fixed areas for citizens.

The number of accidents in school zone is decreasing than before with the introduction of strengthening traffic safety policy since January 2011, but the danger still exists. The School zone sign is widely known to have much effect in protecting children from risks of traffic accidents, but design improvement is being demanded to improve a sense of safety and legibility of safety signs in School zone due to the lack of understanding on the safety signs in crosswalk and School zone. This study analyzed differences in shape and color of existing safety signs through a case analysis of traffic developed countries as America, England, Japan, and Germany and suggested improvement plans for drivers to clearly perceive the school zone. For improvement methods, this study suggested the importance of delivering definite and unified warning message for school zone to drivers by using indication sign and caution sign together, and to use yellow, a safety color, and to unify the safety sign into triangle shape that symbolizes warning and caution to conform the international standards. Actual design production and experiment through improvement plans are needed in the future, and it is expected to secure safety of children and to provide international standardization of safety signs in school zone.

Purpose: A main purpose is to increase the operational rate and reduce operating maintenance costs by Improving the durability of Blower of Military Armored Vehicle and Self-propelled Artillery. As a result, it is expected to improve the service quality of customers. Methods: After analyzing the cause of the stop of the blower, the improvement plans were established and the effectiveness of each improvement plans were verified by testing. Results: Mechanical, electrical and environmental factors affecting brush wear were reviewed, but it was difficult to specify the cause, which necessitated a review of the application of the BLDC motor. Conclusion: After applying the BLDC motor to the blower, tests proved that the existing blower can be replaced. It is expected that this study will help improve the durability life of similar equipment that is applied with Brushed DC motors as well as blowers.
