기계적 합금화법을 이용한 FeTi 수소저장 합금의 개발

申美植,李龍鎬 弘益大學校 科學技術硏究所 1997 科學技術硏究論文集 Vol.8 No.-

In this study, Fe and Ti powders are mechanically alloyed in order to form the FeTi intermetallic compound at ambient temperatures. Fe and Ti powders were weighted to 1:1 molar ratio and the mecahnical alloying was carried out using the Spex mill. The alloying time was varied from 5 hours to 60 hours. Alloying up to 60 hours did not lead to the formation of single phase FeTi compound, instead the peak broadening continued. Most of the unalloyed Fe phase was found to be due to the contaminations from steel container and balls. The heat treatment of the mechanically alloyed powder to 500℃ at a heating rate of 10℃/min followed by furnace cooling in hygrogen atmosphere resulted in the conversion of unreacted Fe and Ti to FeTi as well as activation. The absorption temperature was kept at 30℃. The absorption pressure was measured to be 15.5 atm, the desorption pressure was measured to be 5.4 atm.

김치에서 분리한 Pediococcus pentosaceus 와 Lactobacillus brevis에 대한 녹차 물추출물의 항균효과

신미경,신용서 동아시아식생활학회 1995 동아시아식생활학회지 Vol.5 No.3

In this study, we isolated lactic acid bacteria from kimchi, which were identified as Pediococcus pentosaceus and Lactobacillus bevis by using API 50 CHL Kit, some morphological and physiological tests. The water extract of green tea(50, 100, 500, 1000ppm) inhibited the growth of Pediococcus pentosaceus and Lactobacillus brevis in broth system. Furthermore, their time were prolonged to about 4 hours at 500 to 1000ppm. The leakage amount of intracellular materials and Mg^(++) in tested bacteria cells increased with increasing concentration of green tea water extract.

The heavy metal removability of four kinds of tea was investigated in the various conditions: particle size of tea(10, 35, 70, 100 mesh), concentration of heavy metal(25. 50, 100ppm) and extraction temperature(30, 50. 70, 100℃). The removabilities by the tea solids were increased as the particle size decreased, concentration of heavy metal increased, and extracting temperature increased. Of the four kinds of tea Pb, Cd and Cu removability by Eucommia ulmoides Oliv tea was the highest. In addition, heavy metal removability by Schizandra chinensis Baillon tea was better than that of other tea as extraction temperature was increased.

Abstract-In order to investigate pharmacological properties of New Wonbang Woohwangchungsimwon Pill(NSCH) and Wonbang Woohwangchungsimwon Pill (SCH), the effects of NSCH and SCH on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in mongolian gerbils. The histological observations showed preventive effects of NSCH and SCH treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by SCH treatment. In contrast to what was seen with ATP, lipid peroxide were elevated in vehicle-treated ischemic gerbils. This elevation was inhibited by NSCH and SCH treatments. While NSCH and SCH had no effects on the hexobarbital-induced sleeping time, they prevented the seizures induced by eletric shock and strychnine. NSCH and SCH showed sedative effect in rotarod and spontaneous activity test. Furthermore, NSCH and SCH showed anti-stress effect. Our findings suggest that the pharmacological profiles of NSCH on cerebral ischemia and central nervous system are similar to those of SCH.

Abstract-In order to investigate pharmacological properties of New Wonbang Woohwangchungsimwon Liquid(NSCL) and Wonbang Woohwangchungsimwon Liquid(SCL), the effects of NSCL and SCL on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in mongolian gerbils. The histological observations showed a preventive effect of NSCL and SCL treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by NSCL and SCL treatment. In contrast to what was seen with ATP, lipid peroxide were elevated in vehicle-treated ischemic gerbils. This elevation was inhibited by NSCL and SCL treatments. While NSCL and SCL had no effects on the hexobarbital-induced sleeping time, they showed sedative effect in rotarod and spontaneous activity test. NSCL and SCL prevented the seizures induced by electric shock and strychnine, but the effect of NSCL was less than that of SCL. Furthermore, NSCL and SCL showed anti-stress effect. Our findings suggest that the phamacological profiles of NSCL on cerebral ischemia and central nervous system are similar to those of SCL.

계란 알레르기의 최신 지견

신미용 ( Mee Yong Shin ) 대한천식알레르기학회 2015 Allergy Asthma & Respiratory Disease Vol.3 No.1

Egg allergy is one of the most common food allergies in children and has a wide spectrum of clinical presentation including anaphylaxis. Many studies suggested egg-specific IgE cutoff values (diagnostic decision point) and skin prick test size that predict a clinical allergic reaction without oral food challenges. Some patients may react to all forms of egg including raw egg, but many egg-allergic patients tolerate baked egg products. A few studies reported that a high concentration of ovomucoid-specific IgE antibody indicates a high risk of reacting to heated egg white. Recently it has been suggested that regular ingestion of baked egg products may hasten tolerance development. Egg allergy may be more persistent than previously thought. The treatment of egg allergy still relies on dietary avoidance of egg-containing foods until tolerance has developed. In recent years there has been increasing success in clinical trials of egg oral immunotherapy, and oral immunotherapy can be a promising treatment modality for providing protection from reactions caused by accidental egg exposure. However, concerns regarding the safety and long-term efficacy still preclude the general use of oral immunotherapy in clinical practice. In this article, the recent literature regarding egg allergens, clinical presentation, diagnosis, management and natural history of egg allergy will be reviewed.

국내 모바일 지급결제 서비스에 대한 역사적 고찰 및 시사점

신용재(Yong-Jae Shin*),신영미(Young-Mee Shin) 韓國經營史學會 2016 經營史學 Vol.78 No.-

일반적으로 지급결제란 경제주체들이 경제활동에 따른 채권채무관계를 지급수단을 이용하여 해소하는 행위로 정의된다. 지급결제 방식은 통화를 사용하는 방식으로부터 신용카드 결제 및 계좌 이체와 같은 가상 거래의 방식으로 진화되었다. 특히 근래에 들어서는 스마트폰의 확산에 따라 모바일 지급결제와 같은 방식으로 발전되기에 이르렀다. 그러나 당초 기대와 달리 현재까지 모바일 지급결제 서비스가 충분히 확산되지 못하고 있으며, 일부 서비스의 경우 소비자의 욕구를 충족시키지 못한 채 시장에서 소멸되는 현상을 겪기도 하였다. 본 연구는 그동안 국내에 등장하였던 모바일 지급결제 서비스를 대상으로 한 역사적 고찰을 통해 관련 서비스의 현황을 분석하여 시사점을 제시함으로써 모바일 지급결제 서비스의 활성화에 기여하고자 한다. 본 연구에서 사용된 모바일 지급결제 서비스의 유형은 휴대폰 소액결제, 모바일 신용카드, 모바일 뱅킹, 모바일 지갑 등과 같은 서비스 모델 등이다. 모바일 지급결제 서비스에 대한 현황 분석은 각 서비스의 이용 주체인 사용자를 중심으로 하되 사용자 이외에도 금융권, 이동통신사, 단말기 제조사, 모바일 서비스업자, 가맹점 등의 이해관계자와 함께 정부의 입장도 고려하였다. 본 연구는 모바일 지급결제 서비스를 제공하는 국내 업체들이 대내외 경쟁력을 갖추기 위해 고려할 사항이 무엇인가에 대한 논의의 일환으로 시도되었다. 이러한 점에서 본 연구는 국내 모바일 지급결제 서비스 산업의 활성화 및 발전에 기여할 것으로 기대한다 Along with the widespread of smartphones, firms have agonized over ways to make transactions easier for consumers. These approaches have been attempted from several different angles, as well as by various industries, subsequently leading to the high diversity of mobile payment types provided to consumers. However, unlike the firms expected, mobile payment has not yet widespread enough, and despite their efforts and investments, numerous services have failed due to a lack of consumer endorsement. This thesis aims to historically retrace the mobile payment services that have been attempted domestically, as well as to study the problems the failed services had and the factors the moderately successful services had to be selected. As a frame to view the matter, service models such as mobile micropayments, mobile credit cards, mobile banking, and mobile wallets have been used for distinction, and the positions of each service and their related entities, which are the user, the finance industry, mobile carriers, cell phone manufacturers, mobile service providers, retailers, and government, have all been taken into consideration in the examination. This attempt intends to provide suggestions on points to consider for survival within the competition among global payment services, to prospective domestic mobile payment service firms
