study focusing the changes of repiratory function and blood gas exchange was performed during a control period, during oligemic hypotension and following return of blood to the dogs. Intramuscular morphine and lcoal anesthesia were used. 1. Respiratory rate was variable. It decreased during hypotension. 2. Minute ventilation volume decreased markedly after bleeding and remained at lower level following re-infusion. 3. O_2 utilization of the animals increased shortly after bleeding, but decreased markedly later stage of oligemic hypotension. After return of blood, O_2 utilization returned over to normal levels. 4. Arterial pH showed acidosis during prolonged oligemia and hypotension and showed gradual return to normal after re-infusion. 5. Heart rat increased during hemorrhang and failed to restore normal value. 6. Blood pressure was lower than control after re-infusion. 7. The central venous pressure started at -7∼45mmH_2O. During oligemic hypotension, the pressure fell t -8∼-65mmH_2O and remaine at this level. Following re-infusion the cen venous pressure increased slightly. 8. Arterial hemoglobulin decreased after bleeding and returned to normal after re-infusion. 9. Arterial hemmatocrit dropped during hypoten and returned to normal value with re-infusion. 10. Arterial oxygen content of the animals decreased after bleeding and following reinfusion the oxygen content returned to normal levels. 11. Venous oxygen content decreased markedly during oligemic hypotension and failed to restore normal value with re-infusion. 12. There was a marked increase in the arteriovenous oxygen difference during hemorrhagic hypotension and after re-infusion failed to return to normal. 13. Cardiac output decreased markedly during ligemia and failed to return to normal level after re-infusion. 14. Arterial O_2 saturation decreased after bleeding and returned to normal after re-infusion. 15. Amount of bled blood ranged between 27.2∼37.3cc/kg. It took 3∼4minutes to achiev oligemic hypotension and 2∼3.5 minutes for re-infusion. 16. Rectal temperature was down 0.5∼2.5℃ during hemorrhage and after reinfusion it failed to be normal.

Studies of cardiopulmonary function and acid-base balance were performed on 29 dogs during control period, during oligemic hypotension and following return of blood to the animals. Intravenous morphine and local anesthesia were used. Fifteen of the 29 animals survived the complete experiment. The 14 animals that failed to survive the experimental period died between 15 to 90 minutes after the onset of bleeding. The results were as follows. 1. The heart rate increased after the onset of bleeding and failed to return to control level following reinfusion. Stroke volume decreased markedly after bleeding and failed to recover after return of blood from the reservoir. Cardiac output also decreased during oligemic hypotension and was maintained at this level after re-infusion. Total peripheral resistance decreased significantly immediately after bleeding, however it increased soon over the pre-bleeding level. Central venous pressure decreased after the onset of bleeding and remained at lower level for the rest of the experimental period. Arterial blood pressure, clown to 40-45 mmHg by acute hemorrhage, was elevated near to control level. Left ventricular work decreased tremendously during oligemic hypotension and failed to return to control level with the re-infusion of blood. Hematocrit value showed no significant decrease after bleeding and increased after re-infusion. Hemoglobin decreased after the onset of bleeding and recovered to control value after re-infusion. 2. The respiratory rate fell rapidly after bleeding from 124 to 29 and remained at this lower level for the remainder of the experiment. The tidal volume increased after bleeding and was maintained at this level for the remainder of the experiment. The respiratory minute volume showed no significant changes throughout the experimental period. Oxygen consumption fell lightly in all animals during oligemic hypotension and returned to normal levels following re-infusion. Arterial oxygen content and arterial oxygen saturation decreased following bleeding and the values returned to normal levels after the return of blood from the reservoir The arterio-venous oxygen difference increased after the onset of bleeding. It failed to return to normal values following re-infusion. Arterial $Pco_2$ decreased in all animals after the beginning of the bleeding. Partial pressure of $Co_2$ continued to fall until re-infusion, after which the values returned toward normal. Animals became acidotic. The pH fell to lower level following bleeding. Lactic acid and lactate: pyruvate ratio also increased during same period. Arterial pH and lactic acid failed to return to control value and lactate: pyruvate ratio increased more after re-infusion. Sodium bicarbonate decreased after bleeding and returned to control value following re-infusion.
Na-aginate를 이용한 달맞이유의 캡슐화와 Chitosan을 이용한 2차 코팅

캡슐화는 코팅물질로 내부 물질을 보호하는 기술로서 산패방지등에 대한 보관능력의 개선을 목적으로 많은 연구자들이 식품, 제약, 향료 산업등 여러분야에 적용하기 위해 연구하고 있다. 본연구에서는 달맞이유를 Na-alginate만으로 캡슐화 하는 경우 누출의 문제가 발생하여 Chitosan으로 2차 코팅하여 이를 방지하고자 하였다. 또한, Na-alginate만을 사용한 단일 코팅의 경우와 Chitosan을 이용한 2차 코팅의 경우의 차이점을 비교 분석하였다.
multilingual.js:다국어 웹 타이포그래피를 위한 섞어쓰기 라이브러리
강이룬,소원영 한국타이포그라피학회 2016 글짜씨 Vol.8 No.1
An important issue when typesetting a multilingual article is the visual harmony of multiple typefaces displaying different language systems in the same paragraph. This paper looks at the limitations of user interfaces when dealing with properties of diverse typefaces; provides a survey of existing efforts to overcome such limitations within publishing software; and suggests a method to apply similar functionalities in web browsers. multilingual.js is an open-source JavaScript library first developed during the process of creating the website for 4th ‹Typojanchi›. The library is distributed at http://multilingualjs.github.io, so that it can easily be used by designers working with East Asian languages.
