Meconium aspiration syndrome (MAS) is an important cause of respiratory distress in neonates. Surfactant therapy has been used to improve oxygenation for infants with MAS recently. The object of this study is to estimate the number of candidates for surfactant use in MAS and the cost for surfactant, and to analyze its cost-effectiveness in Korea. Using Korean Health Insurance Review and Assessment Service reimbursement data, the number of neonates with a diagnosis of MAS receiving mechanical ventilation was counted. The annual cost for surfactant use was calculated using the number of patients receiving mechanical ventilation for at least three days who were considered potential candidates for surfactant use. The cost-effectiveness was evaluated using the effectiveness data from a previous metaanalysis. Infants with a diagnosis of MAS receiving mechanical ventilation were 0.92 per 1,000live births annually. Among them, 55% were potential candidates for surfactant use. The expected annual cost for surfactant was 990 million Korean won and 500 million Korean won and the number needed to treat was 14.3 and 6.7 in surfactant bolus therapy and surfactant lavage therapy, respectively. Sixty-four million won was estimated as the cost to prevent one infant death by surfactant bolus therapy and 15 million won by surfactant lavage therapy. The surfactant therapy for MAS is presently not covered by the Korean national health insurance and its application to MAS is limited because of the high financial burden to the patients’ family. This study’s results could help healthcare decision makers establish a policy in the future.

어떤 유형의 원조가 평화에 기여하는가?

최현진,박지연 제주평화연구원 2021 JPI 정책포럼 Vol.2021 No.5

지속적인 국제사회의 원조 공여에도 불구하고, 아프리카의 분쟁국들은 여전히 심각한 수준의 폭력과 빈곤에 노출되어 있다. 과연 공여국은 원조 제공을 통해 분쟁의 종료를 이끌어낼 수 있을까? 어떤 유형의 원조가 내전의 종료에 기여하는가? 본 연구는 정부와 반군이 보유한 자원 간의 균형이 깨짐으로써 대치 상태가 종료 즉, 내전이 종료될 수 있을 것이라 전제하고, 어떤 유형의 원조가 해당 균형의 깨짐에 유의미한 영향을 미치는가를 살펴본다. 구체적으로 OECD 구분에 따른 7가지 유형의 원조를 독립변수로 다루며 2002년부터 2019년까지 아프리카 34개 국가에서 관찰된 모든 내전을 종속변수로 활용하여, 원조 공여와 분쟁 종료 간의 관계를 탐색한다. 콕스비례위험함수모형(Cox Proportional Hazard Model)을 사용한 분석 결과, 아프리카 내전의 종료에 가장 큰 영향을 미치는 원조의 유형은 ‘예산지원(budget support)’이다. 수원국에 대한 예산지원 규모가 큰 경우 혹은 수원국에 대한 예산지원이 급격히 감소하는 경우에 내전이 종료될 확률이 높아지는 것을 확인하였다. 예산지원의 절대 규모가 큰 경우에 정부는 자원 보유에서 우위를 확정함으로써, 반면 절대 규모와 무관하게 예산지원이 급격히 감소하는 경우에는 반군이 자원 보유에서 우위를 점함으로써 상호 간 자원 보유의 균형이 무너지게 되고, 결과적으로 내전의 종료가 관찰되는 것으로 해석할 수 있다.

The purpose of this study was to apply treadmill training through motor learning to cerebral palsy children and examine its effects on their Gross Motor Functions. The subjects of this study were 13 spastic diplegia children who had difficulty in independent gait, and GMFCS level III, IV. We performed treadmill gait training using the principle of weight bearing, based on 4times a week for 30 minutes before and after each session physical therapy we gave weight bearing treadmill training 5 to 10 minutes, during 7 weeks(April 9, 2012~May 26, 2012) fittingly for the children's gait characteristics. In order to test how the weight bearing treadmill training affects spastic diplegia children's gross motor functions, we measured body mobility with Gross Motor Function Measure (GMFM). These data were collected before and after the experiment and analyzed through comparison. Data collected from the 13 spastic diplegia children the results were as follows. For evaluating with regard to change in body mobility, significant difference was observed between before and after the experiment in measured gross motor functions, which were crawling, kneeling, standing, walking, jumping and running(p<0.05). According to the results of this study, when gait training through motor learning was applied to spastic cerebral palsy children, it made significant changes in their body mobility. Accordingly, for the effective application of gait training through motor learning to cerebral palsy children, it is considered necessary to make research from different angle on how such training affects children's mobility, activity of muscles in the lower limbs, and gait characteristics.

Unmanned Aerial Vehicles(UAVs) require collision avoidance capabilities equivalent to the capabilities of manned aircraft to enter the airspace of manned aircraft. In the case of Visual Flight Rules of manned aircraft, collision avoidance is performed by ‘See-and-Avoid’ of pilots. To obtain those capabilities of UAVs named as ‘Sense-and-Avoid’, sensor-system-based intruder tracking and collision avoidance methods are required. In this study, a multi-sensor-based tracking, data fusion, and collision avoidance algorithm is designed by using a model-based design tool MATLAB/SIMULINK, and validations of the designed model and code using numerical simulations and processor-in-the-loop simulations are performed.

최현진,최성대,이태호,김기홍 대한시과학회 2011 대한시과학회지 Vol.13 No.1

목 적: 본 연구에서는 CA(Cellulose Acetate; CA)안경테 전용 가공장비의 40,000 rpm급 고속 주축시스템에 대하여 구조설계 단계에서 안정성을 검토하였다. 방 법: 안경테 전용 주축시스템의 베어링 윤활과 예압구조 선정 및 주축계의 정/동/열적 특성 분석을 통하여 고유진동수, 최대변형, 열변위를 예측하였다. 결 과: 안경테 가공장비 주축의 윤활시스템은 최소미량급유방식인 오일-에어 방식을 채택하였으며 정동적분석 결과 안정성이 확보되었으나, 열변위량은 최대 0.135 mm로 고속 회전 시 주축 발란싱과 성능에 문제가 발생 할 것으로 예측되었다. 결 론: CA안경테 전용 가공장비의 40,000 rpm급 고속 주축시스템을 설계 단계에서부터 윤활 및 예압구조를 선정하였으며, 정동적분석을 통하여 구조안정성이 우수함을 예측하였다. 그러나 회전에 따른 열상승 및 열적변형에 취약하여 이에 대한 대책이 필요할 것으로 나타났다. Purpose: In this study, the stability of high-speed spindle system of CA(Cellulose Acetate) frame equipment for eyewear with 40,000 rpm was examined at the stage of structure design. Methods: Natural frequency characteristics, maximum deformation, and thermal deflection were estimated by analyzing the static/dynamic/thermal characteristics through bearing lubrication and pre-load structure of spindle system. Results: Oil-air type was applied to spindle`s lubrication system, which is the minimal micro-lubrication method. As the result of Static and Dynamic analysis, stability was guaranteed but the maximum 0.135 mm of thermal deflection was found. There were some problems with spindle balancing and performance. Conclusions: High-speed spindle system of CA frame equipment for eyewear with 40,000 rpm, lubrication and pre-load structure were selected from the design stage. Through static and dynamic analysis, excellent stability of structure was proved but thermal rise caused by rotation and thermal deformation were reported. Therefore, this study shows that the related measures may be needed.
