This study was performed to investigate the effects of peking-duck extracts added with medicinal herbs(DJ) on the intoxication of heavy metals (Hg, Pb, Cd, As) in rats. Sprague-Dawley rats weighing 150±15g, were randomly assigned to 5 groups: basal diet only in normal control group(NCG); basal diet and heavy metals without DJ injection in heavy metal control group(HMC); basal diet, heavy metals and DJ(3㎎/㎖) injection in heavy metal low duck juice group(HMLD), basal diet, heavy metals and DJ(30㎎/㎖) injection in heavy metal middle duck juice group(HMMlD); basal diet, heavy metal and DJ(300㎎/㎖) injection in heavy metal high duck juice group(HMHD). Hg and As was injected by 50ppm and Cd and Pb by 25ppm for 17days. Also DJ oral feeding was conducted for 28days. The result of this study were as follows: Food intake and body weight gain in heavy metal administered groups were lower than those of NCG. Liver, kidney and testis weights were not significantly different among 5 groups. GOT, GPT and BUN activities were significantly reduced in DJ treated groups as compared to HMC. DJ showed the suppressing effect on the accumulation of Hg, Pb and Cd in serum, liver and kidney. Fecal Hg and Cd excretions increased with DJ feeding. The results suggested that DJ may have some protective effects on Hg, Cd and Pb intoxication by reducing the accumulation m tissues and increasing excretion. This study also showed the effective way of using duck-extract and its application to the oriental medicine.

변위된 미맹출 상악 견치의 교정 치험례 : CASE REPORT

임혜정,최남기,김선미,양규호 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.3

상악 견치는 가장 긴 치근을 가지며 저작기능과 함께 하악의 측방운동을 유도하고 심미적으로도 치열궁의 구각부위에 위치하여 교합관계의 조화와 대칭을 유지하는 등의 중요한 기능을 수행한다. 상악 견치는 발육기간이 가장 길며 형성되어 맹출하기까지 복잡한 경로를 갖기 때문에 다른 치아보다 매복의 빈도가 높다. 이러한 매복치를 치료하기 위해 임상의는 관찰을 하거나 외과적 노출과 교정적 견인, 자가치아이식, 발치 등 다양한 치료방법을 고려할 수 있다. 외과적 노출과 교정치료는 견치를 교합선상에 배치할 수 있기 때문에 가장 이상적인 접근으로 생각할 수 있다. 본 증례 보고는 구개측으로 매복된 상악 견치를 외과적 노출과 교정적 치아이동을 통해 기능적, 심미적으로 양호한 결과를 얻었다. The maxillary canine is especially important as it has the longest root, provides guidance for lateral movement of the mandible and masticatory function and is a key in esthetics due to its position. Maxillary canine has the longest time to develop and a complex route from the place of formation to the site of eruption, and so it is prone to impaction more than other teeth. The clinician should consider the various treatment options : (a) No treatment and observation, (b) surgical exposure and orthodontic traction (c) autotransplantation (d) extraction. Surgical exposure of the canine and orthodontic treatment to bring the tooth into the line of occlusion is considered the most desirable approach. This case presents the results of treatment for impacted maxillary canine by surgical exposure and orthodontic tooth movement.

윈도우즈에서 지원하는 미디어 플레이어는 기본적인 재생기의 기능과 더욱 다양한 음악과 선택 기능을 제공하며 최신 휴대용 장치에 고품질의 음악과 비디오, 사진을 동기화할 수 있는 기능 등 다양한 기능을 가지고 잇지만, DVD 등의 매체에서 지원하는 동영상 검색 기능은 지원하지 않는다. 재생기의 고유 기능인 재생에 초첨을 맞추고 재생과 관련한 여러 기능을 Microsoft에서 지원하는 DirectShow을 이용하여 구현한다. Free Player는 다양한 시간에 따른 검색기능, 노트 입력 기능, 내용에 따른 목차(TOC: Table of Contents) 지원 등을 제공한다. 이는 이용자의 동영상 검색에 도움을 줄 것으로 기대된다. Recent advances in multimedia processing technologies, internet-working technologies, and the World Wide Web phenomenon have resulted in a vast creation and use of digital videos. However, the functions of a video player has not been changed significantly since the analog video-cassette recorder (VCR) has been invented in 1970s and 80s. In this paper, we present the design and implementation of a video browsing system that lets the user view a summary of a selected video and give her feedback so that the user can use relevance of the video provided by herself or other users. We called the player as 'Free player'. The 'free player' is implemented with Visuall C++ and DirectShow supported from Microsoft. In addition to basic VCR-style functions, play, stop, and pause, the proposed player has speed-up playback features, audio featurs, search features using time, and a full-screen feature. The highlights of the proposed player are personal notes that are anchored to the video timeline and TOC that help for navigation.

김혜숙,윤영임,조은정,최윤희,오미영,김영관 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A

This research was carried out to find out the possibility of using Faraday's law in analyzing the electrocoagulation system. Bench-scale reactor equipped with aluminum electrode plates was operated using synthetic wastewater which received sodium chloride for conductivity adjustment. Phosphate was added to the wastewater to induce the precipitation with Al. The amount of aluminum dissolved from the electrodes could be predicted by Faraday's law with a difference less than 5%. This difference was greater at a higher electric current, probably due to the increased solution temperature. However, effect of pH on the dissolution of the aluminum was negligible. The result of this study suggested that the operating condition of electrocoagulation system could be developed using the Faraday's law when the pollutant concentration is given.

Purpose : We have evaluated the outcomes of peritoneal dialysis in patients with metabolic crises caused by in born error of metabolism. Methods : There are 6 patients(8 episodes, 4 males and 2 females) who had inherited inborn errors of metabolism and were admitted to the department of pediatrics, Shoonchunhyang university hospital in Seoul from December 1991 to December 1994. The technique of dialysis is discribed, in short: A Tenckhoff catheter was inserted surgically in all patients through the lateral abdominal wall. Commerically available dialysate solutions(Peritosol, Korea Green Cross Co.) was applied to 5 patients(7 cases) with hyperammonemia. In a patient with propionic acidemia, we used a special custiom made dialysate that replaces lactate by bicarbonate. Results : 1) The mean age was 5.3 months old. There were 6 patients with 8 episodes. Six cases had Ornithin transcarbamylase deficiency. The remaining cases are Multiple carboxylase deficiency and Propionic acidemia (Table 1) 2) In 7 cases with hyperammonemia, mean levels of pre and post 24hrs peritoneal dialysis serum ammonia were 1000.2±310.9 ㎍/dl and 388.8 ±156.7 ㎍/dl at 24 hours respectively. Time on serum ammonia levels reached below 300 ㎍/dl was 88.7 ±39.6 ㎍/dl hours. 3) Four out of seven cases were a recorvert of mental status. Each episode of serum ammonia mean levels was 388.8 ±156.7 ㎍/dl after 19.7 ±5.8 hours of peritoneal dialysis (Table 3). 4) Peak serum ammonia levels of the survived group reached 1356.5 ㎍/dl, higher than the expired group of 847.5 ㎍/dl and time period of starting peritoneal dialysis after onset of the survived group was 15.5 hours earlier than the expired group of 23 hours(P>0.05)(Table 4). 5) 3 out of 7 cases of hyperammonemia died. The cause if death were 3 brain edema, 1 hyperkalemla and 1 intracranlal hemorrhage. 6) In onecase with Multiple carboxylase deficiency, serum ammonia level was normalized after 12 hours of peritoneal dialysis. The reduction of serum levels of the branched amino acid was also observed. 7) In a case of Propionic acidemia with severe metabolic acidosis, the prior serum bicarbonate level was 8 mmol/L and was increased up to 18 mmol/L by peritoneal dialysis lasting 19 hours. 8) Among 8 cases, complications of peritoneal dialysis were 5 hypoalbuminemia, 4 hyoercalcemia, 4 hyperglycemia and leakage of peritoneal dialysate. Conclusions : In cases of hyperammonemia, survival rate is 57.1%. They are showed excellant efficacy of treatment of peritoneal dialysis for metabolic crises. In a case of propinic acidemia is fastly corrected by peritoneal dialysis. But unfortunally clinical manifestations is not improved. Therefore, further studies is required with treatment of severe metabolic acidic conditions.

성장기 아동의 Ⅲ급 부정교합의 치료에는 많은 악기능 정형장치가 사용되어 왔으며 다양한 형태로 변화하여 발전되어 왔다. Horseshoe appliance는 Schwarz에 의해 소개된 장치로서 elastic의 견인력으로 장치의 free sliding 효과를 통해, 하악와와 과두의 관계를 재정립시켜, 악골 주위의 연조직이나 muscle matrix와 조화되는 새로운 위치에 하악골을 repositioning시켜 악골관계를 개선시킬 수 있다. 또한 하악의 후하방 회전 효과를 극소화시켜 전안면고경의 증가를 방지할 수 있고, 구외 장치에 비해 환자의 협조도가 좋다. 저자들은 전치부 반대교합을 주소로 전북대학교 치과병원 소아치과에 내원한 Ⅲ급 부정교합 환자에게 Horseshoe appliance를 사용한 결과 하악골에 대한 상대적인 상악골의 전방 성장과 교합평면의 반시계방향 회전, 상악 전치의 순측 경사와 하악 전치의 설측 경사로. 3개월 내에 전치부 반대교합이 해소되는 효과를 얻었다. The Horseshoe appliance was introduced by Dr. Schwarz, and it is used to correct sagittal relationships by elastic force in class Ⅲmalocclusion.It minimizes the increment of lower anterior facial height and allows the mandible to be repositioned harmoniously with the soft tissue and muscle matrix of the jaw. It has the advantages of better patient cooperation, easier construction, and more effective modification. In the patients who were treated with Horseshoe appliance, forward growth of maxilla and counterclockwise rotation of occlusal plane with labioversion of maxillary incisors and linguoversion of mandibular incisors were obtained Minimum downward and backward rotation of mandible was accepted, so increasing of lower anterior facial height was minimized.

楊善惠,崔東勳,지혜미,金恩貞,金彰昊 동아대학교 환경문제연구소 1996 硏究報告 Vol.19 No.1

This study was carried out to interpret hydraulic behavior and CO₂gas desorption in countercurrent packing tower which packed 50 mm plastic Hiflow-ring. The results are as follows: 1. To compare with conventional packing, 50mm Hiflow-ring could save energy because of low pressure drop under high load. 2. As relative error between calculated value and investigated value was less than 6% in the loading point and flooding point we found that we can predict results mathematically which occurres in the packing tower. 3. The unique magnituteds of packing which was used are as follows. C_(L) = 2.1×10^(-4), n = 0.787 so we can predict efficency which occurres.
