Recently many small and mid-sized hospitals are closing down or experiencing financial difficulties. As a result, in order to provide exceptional service that would increase their competitiveness, they implemented telemedicine service for the prescription of medicine necessary before a colonoscopy. This study is an analysis of how telemedicine service affects patient satisfaction. Through the focus group interview (FGI) of medical service providers, regarding telemedicine service and face-to-face service, it was appraised that telemedicine service was more effective than face-to-face service. Afterward, a second survey aimed at endoscopy patients was conducted in order to find out the value of telemedicine service. First, through the analysis of the three main factors of telemedicine service, conclusions were drawn(safety/reliability, convenience/rapidity, and economics). A follow-up analysis showed that convenience/rapidity had the greatest effect on telemedicine service satisfaction. Next the factors of the quality of medical service were analyzed and 3 main factors were deduced (the superiority of the external and internal environments/appropriateness, superiority of the medical team, telemedicine service). A follow-up analysis found that telemedicine service had the greatest effect on patient satisfaction. This study found that providing exceptional medical service that utilizes telemedicine service would improve patient satisfaction. Therefore, we would be able to form a strategic plan that would strengthen the competitiveness of small and mid-sized hospitals.

Fire detectors are designed to minimize loss of life from a fire alarm system as an alarm to help evacuate more quickly until the completion of the evacuation alarm should be continued. the purpose of such alarms in order to achieve the characteristic fire heat release rate reaches a certain level, or when a certain time has elapsed, when the heat detector is to be alarms to answer. Requires a quick response, it is desirable to install the sensor as much as possible, but taking into account the cost of installation problems by engineering approach to minimize the quantity and rapidity of detection capability should be increased. In order to increase the rapidity of fire detectors in a room according to the height of the sensing period is to be maintained the optimum distance of the fire detector detects characteristics should be considered. Differential spot-type heat detectors installed domestic basis, depending on the type of sensor that can detect one sensor area is limited and less than 4m ceiling height regulations and simply double the number in excess of 4m and intended to be installed.

본 연구의 목적은 기존 자동심장충격기인 T-AED와 새롭게 개발된 SC-AED의 제세동 신속성 및 사용자가 느끼는 주관적 편의성을 비교하는 것이다. 2017년 2월부터 2018년 4월까지 전남지역의 D대학, C대학병원의 기본인명소생술 교육센터에서 의료종사자 및 일반인을 위한 기본소생술과정에 참여한 156명을 T-AED (n = 77) 및 SC-AED (n = 79) 그룹에 무작위할당 하였다. 각 그룹은 제세동을 실시한 후, 총 제세동 지연시간, 제세동 지연시간, 쇼크버튼 누름 지연시간, 후속 흉부압박 재개시간까지의 시간을 측정하였고 이를 t-검정을 통해 분석했다. 실험 후 조작자신감, 사용편의성, 의사결정 도움, 이상 3가지 요인에 대한 자료를 설문으로 수집하였고 각각 t-검정을 통해 분석하였다. SC-AED는 T-AED와 비교하여 총 제세동 지연시간(11.22 초), 제세동 지연시간(11.04 초) 및 쇼크버튼 누름지연시간(2.15 초)가 현저히 단축되었습니다 (p<0.001). 주관적 편의성 측면에서 자신감(T-AED : 7.62±1.25VAS vs. SC-AED : 7.80±0.98VAS, p = .358)는 중요하지 않았지만, 편의성(T-AED : 7.05±1.36VAS vs. SC) -AED : 8.95±0.89VAS, p<0.001) 및 의사결정도움(T-AED : 6.58 ± 1.73VAS vs. SC-AED : 9.08±0.98VAS, p = 0.001)은 유의한 차이를 보여주었다. 결론적으로 T-AED에 비해 의료종사자 및 일반인 집단 모두에서 더욱 신속한 제세동을 가능하게 하였으며, 사용자의 편의성과 명확한 의사결정을 크게 도와주었다. SC-AED에 적용된 기술이 향후 보편적인 자동심장충격기에 상용화된다면 더욱 효과적인 PAD를 통해 심정지 환자의 생존율 제고에도 이바지할 것이다.

The wetlands are facing environmental changes such as desiccation that occurs with the passage of time and reduced ecosystem services from wetlands in the city. In order to maintain the ecosystem services provided by wetlands in urban areas, a system thinking about the trade-off phenomenon of ecosystem services occurring as the wetlands undergo environmental changes is needed. Therefore, the purpose of this study is to develop strategies for wetland design using system thinking approach to enhance the resilience of ecosystem services degraded by the desiccation of wetlands and other disturbances. The objectives of this study include the system boundary and variables. Second, analyzing the dynamics of wetland design strategy. Third, it analyzes the trade-off phenomenon of ecosystem services in terms of the hydrology, hydric soil, and plants strategies to mitigate these effects. Fourth, wetland basic design to improve the resilience of ecosystem services. A wetland in Abuk-Mountain Neighborhood Park, Miryang-si, Gyeongsangnam-do, has been selected as a case study. Causal loop diagrams(CLDs) are used to analyze feedback in the wetland regime. In summary, hydrology, hydric soil, and plants is suggested as system boundaries to design plan. Design strategies for the wetland focused on robustness, redundancy, rapidity, and resourcefulness as a result of CLD analysis are first proposed in order to effectively maintain the wetland regime over the long term. Secondly, in a section related to hydrology, the CLD results show the trade-offs between provisioning-cultural services and regulating services. In order to control these services, a "water cycling system" has been implemented due to its strength in terms of robustness. The CLDs for hydric soil showed the trade-offs between regulating services and supporting services. An "installation of storm drainage for maintaining water levels" was selected due to the strength offered in terms of redundancy and rapidity. The CLDs for plants showed the trade-offs between provisioning - cultural services and regulating services. In order to control the strategic points, the "planting of indigenous vegetation" was suggested given the strength in terms of redundancy. In this study, a wetland design method is proposed that can improve the resilience of wetland ecosystem services by analyzing the dynamics overtime. The results of this research can theoretically be applied to help restore ecosystem services in wetlands using ecological landscape design. In addition, this study will contribute to reducing maintenance costs by improving wetland resilience.
