The present study has been conducted to design a high efficiency impeller for a centrifugal chiller with the refrigerant R134a. In this study, we considered a harmony between impeller and diffuser in full load and part load condition. To get a high efficiency and reliability in suitable range, the numerical analyses were carried out at the various flow rate. A finally designed compressor was investigated experimentally to check the performance. The analysis data coincides with the test result of the compressor quite well and also the data in this study would be useful for an expanded capacity of an impeller to improve compressor efficiency.

During the Crimean War in 1859, Nightingale, who served as a nurse during the War, claimed that the treatment environment had a significant impact on the mortality of the wounded. They figured that Hospital Architecture, Design, Light, and Ventilation System are the factors that enhance the health of the patient"s. Therefore, they suggested Pavilion hospital environment which brings well-lighted Ventilation System. Despite these reasons, the hospital, which is currently the target of this study, is still unable to provide the necessary treatment environment for patients. Therefore, by understanding the concepts of hospitals and renovations, and by analyzing the quality of the facility, this study seeks the rehabilitation plan in order to provide a pleasant treatment environment for patients.

증례보고 : 특발성 척추 측만증 수술 중에 발생한 악성 고열증

Malignant hyperthermia is a potentially fatal hypermetabolic syndrome characterized by skeletal muscle rigidity and hyperpyrexia. We had an 11-year-old female presented for a surgery for idiopathic scoliosis of the thoracic vertebra. Generalized muscle rigidity and tachycardia were revealed 1 hour 35 minutes after isoflurane administration. Then the body temperature was risen to 43℃ within 10 minutes and the arterial blood gas analysis showed a severe respiratory and metabolic acidosis. Under the suspicion of malignant hyperthermia, the patient was treated by discontinuing all anesthetic agents, hyperventilation with 100% oxygen, surface cooling with ice pack and the administration of dantrolene sodium. But, the patient died of renal failure and disseminated intravascular coagulation after 50 days postoperatively. (Korean J Anesthesiol 2009;57:656∼61)

This paper describes the results of the performance analysis of the airfoil-shaped concentration device installed above a building for BiWP(Building-integrated Wind Power) which recently attracts attention as a local power. The effects of the airfoil-shaped concentration device above a building on the wind velocity increasement examined by a series of detailed numerical analysis using CFD and wind tunnel test. The results show that the airfoil-shaped concentration device above a building increase the wind velocity from 120% to 150%.

최근 건축물에너지 절감 및 온실가스 감축에 획기적으로 기여할 수 있는 제로에너지빌딩에 대한 관심이 높아지고 있으며 신재생에너지 의무화 비율 만족을 위하여 신재생에너지 중 태양광과 지열에너지의 공동주택으로의 적용에 대한 시도가 건설사 위주로 적용이 활발히 진행되고 있으나, 태양광 에너지만으로는 부지면적 확보등과 같이 의무화 비율 만족이 어렵기 때문에 지열에너지의 활용과 같이 융합에너지 적용이 절실한 실정이다. 저탄소 녹색성장 실현 및 에너지 소비 최소화를 위하여 신재생에너지 사용은 필수사항이며, 다양한 부하패턴에 대한 대응과 냉난방 부분 에너지 소비 최소화 및 열원간 경쟁력 확보를 위해서는 지열시스템의 최적화 설계가 진행되어야 하고, 에너지 절감 운영에 대한 방안이 필요하다.

한국의 교통계정 개발과 적용에 관한 연구

김한영(Han-Young Kim),이원영(Won-Young Lee) 한국철도학회 2009 한국철도학회논문집 Vol.12 No.6

본 논문은 우리 실정에 맞고 국제비교에도 활용할 수 있는 국가차원의 교통계정 기본틀을 제시하였다. 기본틀은 비용ㆍ수입항목과 산정 방법론으로 구성되어 있다. 그리고 제시된 우리나라의 교통계정을 적용해본 결과, 국내총생산 대비 도로교통의 총비용은 유럽보다 3.23% 높은 것으로 나타났고 철도교통의 총비용은 유럽보다 0.67% 낮은 것으로 나타났다. 또한 도로교통과 철도교통의 단위당 비용을 비교한 결과, 여객의 인-km당 도로교통 비용이 철도교통 비용의 약 4.8배, 화물의 톤-km당 도로교통 비용은 철도교통 비용의 약 2.4배로 나타났다. This paper proposed the framework for the Korean transport accounts which is suitable to Korean situation and can be used for international comparison. The framework is composed of the costs, the revenues and the estimation methodology. This framework is applied to both the Korean road and rail transport, respectively. The result showed that the total cost compared to GDP for the road was higher than the Europe's by 3.23% and that for the rail was lower than the Europe's by 0.67%. Also, the result showed that, in terms of the unit cost, the passenger cost per person-kilometer of road transport was 4.8 times higher than that of rail transport and the freight cost per ton-kilometer of road transport was 2.4 times higher than that of rail transport.

Therapeutic Applications of Stem Cell-Engineered Nanovesicles Endowed with Magnetic Properties

Han Young Kim(김한영) 한국고분자학회 2021 한국고분자학회 학술대회 연구논문 초록집 Vol.46 No.2

Owing to their unique properties, mesenchymal stem cell (MSC)-derived exosomes have been actively studied for treatment of wide variety of diseases. However, it still remains challenging to improve the therapeutic outcomes of using exosomes to treat those diseases. Very small quantities of exosomes are released from MSC, and MSC-exosomes poorly accumulate in target tissue after systemic administration. In this study, iron oxide nanoparticles (IONP) were introduced to MSC and the exosome-mimetic nanovesicles were isolated. Treatment of IONP contribute to enhanced expression of therapeutic growth factors in MSC, which are attributed to IONP that are slowly ionized to iron ions. Isolated nanovesicles incorporate not only IONP which act as magnet-navigating tool, but also large amount of therapeutic growth factors. In this thesis, in vivo systemic delivery of IONP-harboring nanovesicles and their therapeutic effects in central nervous system lesions or in injured myocardium are presented.
